Based on the successful experience and lessons of Chinese agricultural development,Deng Xiaoping creatively set forth a series of thoughts on agriculture,rural areas and peasants from emancipating the mind and seeking truth from facts.The thoughts are the most basic theory which instructs the work of Chinese agriculture and rural areas.Scientific analysis of these thoughts has the great significance in deepening agricultural reform,developing agricultural economy and promoting cross-century development of Chinese agriculture and rural economy.


Abstract Phytochemical studies on the leaves of Ailanthusaltissima (Simaroubaceae) have not been reported previously.Thus, the authors isolated and identified secondary metabolitesfrom A. altissima. Dried and powdered leaves were extracted with80% aqueous methanol, and the concentrated extract wassuccessively partitioned with ethyl acetate, n-butanol, and water.Four flavonoids were isolated from the ethyl acetate fractionthrough repeated silica gel and octadecyl silica gel columnchromatography. Spectroscopic data including NMR, MS, and IRallowed for identification of the chemical structures as quercetin(1), afzelin (2), quercitrin (3), and isoquercitrin (4). This is the firstreport of the isolation of these compounds from A. altissima. Thefour isolated flavonoids 1–4 as well as solvent fractions (ethylacetate, n-butanol, and water), were evaluated for DPPH radicalscavenging activity.Keywords afzelin · Ailanthus altissima · DPPH assay · isoquercitrin · quercetin · quercitrinIntroductionAilanthus altissima Swingle (Simaroubaceae), also known as tree-of-heaven, is a deciduous tree distributed mainly in China,Mongolia, Japan, and Korea (Feo et al., 2005). The diameter of amature A. altissima tree is about 50 cm with stems grows up to30 m. The upper sides of the leaves of A. altissima are dark green,while the under side is dark red. Flowers of A. altissima appearbeginning from the end of June and the seeds is included in flowerinside of the propeller shape. A. altissima has been used inChinese traditional medicine as a bitter aromatic drug for thetreatment of colds and gastric diseases (Feo et al., 2003; 2005).Some compounds isolated from the root and bark of the planthave been reported to have insecticidal (Kraus et al., 1994),antimalarial (O'Neill et al., 1986; Bray et al., 1987), antitumor(Casinovi et al., 1983), antitubercular (Rahman et al., 1997),nervous depressant (Crespi-Perellino et al., 1988), antiproliferative(Hwang et al., 2002), anti-Epstein-Barr virus (Kubota et al., 1997),alleropathy (Heisey et al., 1990; 1996), anti-inflammatory (Jin etal., 2009), and antioxidant activities (Okunade et al., 2003; Lee etal., 2005; Tamura et al., 2006; Zhang et al., 2007; Rahman et al.,2009). There have been some reports on the isolation of secondarymetabolites from the cortex and roots of A. altissima. However,there are only a few studies that have evaluated the leaves of A.altissima with respect to their biological and phytochemicalproperties. In addition, DPPH assay performed with an alcoholextract of A. altissima leaves showed significant activity. Therefore,this study was initiated to identify the principal antioxidantcompounds from A. altissima leaves.Antioxidants are useful chemical materials for preventingoxidative deterioration of biomolecules and are widely applicableas ingredients of food supplements, cosmetics, and medicines.Many plants contain substantial amounts of antioxidants such asvitamin C, vitamin E, carotenoids, flavonoids and tannins that canbe utilized to scavenge excess free radicals from the human body.Indeed, many researchers have found efficient antioxidants in plants.


Since the reform and opening up,China's economy has a rapid development,and the factory has sprung up all over the country.As an important part of enterprise production cost,power consumption of factory is closely related to the economic benefits of the enterprise to a great extent and is the key for enterprise survival and long-term development.Therefore,with the degree of China's energy saving and emission reduction increasing and the energy cost rising,how to realize the energy-saving of electrical engineering and promote enterprise energy conservation has become the problem that most enterprise face and need to solve.This article mainly discussed the application of energy-saving technology in electrical engineering of China's factories and put forward corresponding opinions.


Laonome calida Capa, 2007, a feather-duster worm discovered in 2007 in estuaries and open water of tropical and subtropical Australia, was recently found at many locations in fresh and brackish waters of the delta region of the rivers Rhine, Meuse, and Scheldt in the Netherlands. Morphological differences between specimens from Australia and the Netherlands are insufficient to warrant specific distinction. A recent translocation from Australia to Europe, or from a third country to both, may explain the disjunct distribution of this species. A table with translocated and cryptogenic sabellids reported to date is provided.


This study begins to explore ways in which the principles underpinning the traditional 'nurture group' model could be altered and age ranges extended while continuing to deliver the proven success of nurture groups in promoting children's social and emotional development. Part-time nurture groups were established in four different primary schools within the same council area. A total of 25 pupils ranging from age four to ten years attended the nurture groups for the 2006/7 school session and a control group was established within each school. All fifty children were tested using the Boxall Profile, literacy, numeracy and motor skills baseline assessments at pre-, mid- and post-nurture group intervention. Analysis of the results showed that for the children who had received a part-time nurture group experience, statistically significant gains were made in the areas of development assessed by the Boxall Profile. Gains were also made in the areas of literacy, numeracy and motor skills; however, these gains were not at a statistically significant level. Results also show that the younger the pupil accessed the nurture group, the more significant gains were made in the measures used. [ABSTRACT FROM AUTHOR]


Smart radiation device (SRD) based on the asymmetrical Fabry-Perot cavity automatically tune its IR emittance depending on the ambient temperature, making it an ideal choice for thermal control system of spacecrafts. The low solar absorption is desirable for SRD to prevent the spacecraft from overheating by sun light. In this paper, a multilayer highly reflective film with LH stacking layers is designed to reduce the solar absorptance (A ) of the Ag/Al2O3/VO2 structured SRD. The reflective film achieves a high reflection band in ~220 nm bandwidth from 460 nm to 680 nm, which results in a reduction of the solar absorptance by 25.56 % for SRD working at low temperature and 24.27 % at high temperature as the stacking factor k 5. The simulation results indicate that an economic reflective film with k 3 can achieve effective suppression of A of SRD, demonstrating the promising potential of the proposed reflective film in thermal control application of spacecrafts.


Some Chinese cities are now notoriously known as "ghost cities" for their empty skyscrapers, luxury apartments and magnificent squares. These "ghost cities" are a result of excessive housing and infrastructure construction, and speculation on property demand. The emergence of ghost cities is a consequence of China's land-centred urbanisation. Land-centred urbanisation is rooted in local GDPism, which in turn results in aggressive developmentalism and excessive investment among China's local governments.


The utility model relates to an LED (Light Emitting Diode) lamp tube with a rotational lamp cap. The LED lamp tube is characterized by comprising a lamp panel (1), wherein an LED lamp (2) is arranged on the lamp panel (1); a heat-radiating element (3) is connected to the bottom surface of the lamp panel (1); a lamp shade (4) is arranged above the LED lamp (2); a lamp cap tubular seat assembly (5) is connected to one end of the lamp panel (1); a lamp cap socket assembly (6) which can rotate in the lamp cap tubular seat assembly (5) is connected to one end of the lamp cap tubular seat assembly (5); and the lamp panel (1), the LED lamp (2) and the lamp cap socket assembly (6) are electrically connected. The lamp cap socket assembly and the lamp cap tubular seat assembly of the LED lamp can relatively rotate, thus changing the illumination angle and widening the application range of the LED lamp.


Heart diseases still contribute as the highest cause of death globally. It is also well-known that hypertension and high blood cholesterol are the key risk factors for heart diseases. This emphasizes that more preventive efforts are urgently needed. One common preventive method is to conduct a 24-hour ambulatory setting for blood pressure (BP) monitoring. With this monitoring, the doctors can give the patients a more precise treatment/medication at the earliest stage before the disease develops into a much-worsening state. However, the established methods use cuff-based devices. This is indeed very inconvenient and painful for the patients. Hence, a cuff-less BP monitoring device and system becomes the ideal solution. Furthermore, our daily activities including habits and food/drink intake can also trigger the increase/decrease of BP. This where the use of wearable and flexible devices for BP monitoring plays an important role. Thus, we provide a minireview on how the BP can be estimated using cuff-less methods and also how the flexible materials crucially support the realization of wearable cuff-less BP monitoring devices and systems by providing more comfort to wear and more cardiovascular health assessment as well as more electronics functionalities.


In the last three years, the world has experienced one of the worst banking catastrophes in its history. In the United States alone, some 282 banks have failed since January 2008. This burgeoning devastation has catapulted the Federal Deposit Insurance Corporation ("FDIC") to the forefront of crisis-management as it acts as receiver for each of these failed institutions. With high stakes, vast consequences, and little time to dither, the receivership process and its participants require stable, clear and predictable jurisprudence. One issue, however, continues to elude these jurisprudential virtues: is the FDIC, when acting as a failed bank's receiver, considered an agency of the United States, or merely a private party? Surprisingly, the answer is far from clear, and the ramifications significant and numerous. Years of judicial analysis have produced cacophony, not chorus, and there is a startling absence of scholarly exposition. This article, after outlining the problem, delineates and critically evaluates two solutions.

Through the in-depth analysis of a single fanwork, Luminosity's concept-vid Scooby Road (2005), made with images appropriated from the acclaimed TV series Buffy the Vampire Slayer, this paper will investigate the strong and complex relationship between fan communities and media. A vid is a form of remix that consists in appropriating clips from movies or TV shows, and setting them to music. The author of the remixed work, the vidder, uses editing strategies in order to comment upon the sources, criticize them or praise them. Building on the concept of fandom ecology, and providing an overview of the main characteristics of the vidding community, this paper will focus on how the shared knowledge of both the original work and of fannish interpretations of such work, combined with fannish conventions and modes of media consumption, shape fandom creative productions. After examining the relevance of Buffy the Vampire Slayer for the vidding community and its history, we will then focus on Scooby Road's peculiar context of creation and distribution, and proceed to analyze several of the fifteen vids that compose this peculiar, 42- minute concept-vid.


The solution-phase thermolysis of (formazanate)boron dihydrides (LBH2; 2) results in the formation of aminoborane compounds (4) via a series of boron-to-ligand intramolecular hydride transfer reactions. Monitoring the reactions by NMR spectroscopy allowed identification of several intermediates, and a reaction mechanism is proposed. In the case of a ligand with an N-Mes substituent it was possible to characterize an intermediate (7b-i) during this transformation that shows an unexpected cyclohexadiene moiety, which results from hydride transfer to the ortho-position of the mesityl substituent. Two consecutive boron-to-ligand hydride transfers eventually result in reductive N–N bond cleavage to give triazaboroles as the final product.


An integrated reaction–distillation process for the production of methylal from aqueous, methanolic formaldehyde solutions is developed. The process consists of a serial connection of a reactor in which the feed is converted to chemical equilibrium by a heterogeneously catalyzed reaction followed by a pressure-swing distillation sequence, in which a heterogeneously catalyzed reactive section as well as a vapor side draw are used. The catalyst is an acidic ion-exchange resin. The process yields methylal in purities over 0.999 g/g; methanol can be recovered in purities over 0.94 g/g, and water is withdrawn in a purity of 0.99 g/g. The conversion of formaldehyde is above 99.9%. The process development is carried out based on steady-state simulations with a model which explicitly accounts for the oligomerization reactions of formaldehyde in aqueous, methanolic formaldehyde solutions. The model is validated by a comparison to experiments that are carried out in a laboratory glass distillation column.


Background: Congenital heart diseases are malformations formed during the first weeks of life. Thanks to advances in medicine, they could be cared properly and pregnancies on heart diseases could be continued and completed. These malformations are sources of morbidity even high maternal fetal mortality. Whence our motivation to carry out this study and improve its care.Methods: This is a retrospective observational study reporting clinical cases of congenital heart disease pregnancies, only seen at the UHC-GOB over a seven years period (01 February 2007 - 28 February 2014).Results: We have identified 10 cases of congenital heart diseases out of 56 320 deliveries, that is, an incidence of 0.12 per 1000 deliveries. Isolated arterial canal persistence is predominant. The average age is 26±1. Four cases of congenital heart diseases diagnosed and repaired during childhood, have been noted as well as 02 cases of fortuitous discovery during pregnancy. No joint obstetric and cardiac follow up was performed for our patients. Delivery by high way is recommended in 70% of cases which 57% under peridural anesthesia. Half of the patients had peri-gestational cardiac decompensation such as dyspnea, pre-eclampsia and vacuo-shock progressively decreasing in post-partum. On the fetal side, we recorded 01 intra-uterine delayed growths, 03 premature births and 02 deaths.Conclusions: Pregnancy prognosis on congenital heart disease is based on the type of malformation, close follow up and a multidisciplinary care (Gyneco-obstetrician, Cardiologist, Reanimator, Pediatrician and Geneticist.

The cy-pres doctrine is a well-known privilege of charity law. In the testamentary context, its function is to keep property in charity which might otherwise lapse into residue and then fall into private hands. In wills cases, the doctrine applies where a testator has made a failed gift. It permits a scheme to be written correcting the defect in the bequest. The change made by the scheme is often far-reaching. Turning a failed gift into a successful one will normally mean a substantial rewrite of the donor's wishes. And so it is a doctrine of consequence, allowing direct intervention into the disposition of property.

PROCEEDINGS IN PETTY OFFENCE CASES RELATED TO EMPLOYEES AND OTHER PERSONS ENGAGING IN GAINFUL OCCUPATIONIn the study, the proceedings in petty offences have been described in terms of the tasks imposed by law on work inspectors. Liability for an offence is a criminal liability sensu largo, and the proceedings in petty offence cases are similar to criminal proceedings. In cases provided for in the act, a work inspector conducts explanatory investigation in the course of which he may impose a fine on the offender, be satisfied with applying educational measures only or decide to file a motion for punishment in the court. In the latter case, after instituting the proceedings by the court, the work inspector acts as a public prosecutor. Issuing a sentence punishing for an offence, the court, as a rule, specifies the character of legal relationship between the employer and the wronged person.

The utility model has the advantages that the pollution source real-time monitoring system can analyze data in real time, can display the processing result in real time and can solve the problems that the data is not acquired in real time and the acquired data is in idle state because the acquired data is not analyzed and utilized in real time; and the impact of the pollution source on the environmental quality can be reflected in real time and the problems of pollution emission abnormality and the like are handled as early as possible, so proper countermeasures can be taken.


Background: Global structural changes occur in the ryanodine receptor (RyR) upon ligand activation. Results: Different ligands induce different conformational changes in the clamp region of RyR. Conclusion: Conformational changes in the clamp region of RyR are ligand-dependent. Significance: RyR possesses multiple, ligand-dependent gating mechanisms associated with distinct structural changes. Global conformational changes in the three-dimensional structure of the Ca2+ release channel/ryanodine receptor (RyR) occur upon ligand activation. A number of ligands are able to activate the RyR channel, but whether these structurally diverse ligands induce the same or different conformational changes in the channel is largely unknown. Here we constructed a fluorescence resonance energy transfer (FRET)-based probe by inserting a CFP after residue Ser-2367 and a YFP after residue Tyr-2801 in the cardiac RyR (RyR2) to yield a CFP- and YFP-dual labeled RyR2 (RyR2Ser-2367-CFP/Tyr-2801-YFP). Both of these insertion sites have previously been mapped to the "clamp" region in the four corners of the square-shaped cytoplasmic assembly of the three-dimensional structure of RyR2. Using this novel FRET probe, we monitored the extent of conformational changes in the clamp region of RyR2Ser-2367-CFP/Tyr-2801-YFP induced by various ligands. We also monitored the extent of Ca2+ release induced by the same ligands in HEK293 cells expressing RyR2Ser-2367-CFP/Tyr-2801-YFP. We detected conformational changes in the clamp region for the ligands caffeine, aminophylline, theophylline, ATP, and ryanodine but not for Ca2+ or 4-chloro-m-cresol, although they all induced Ca2+ release. Interestingly, caffeine is able to induce further conformational changes in the clamp region of the ryanodine-modified channel, suggesting that ryanodine does not lock RyR in a fixed conformation. Our data demonstrate that conformational changes in the clamp region of RyR are ligand-dependent and suggest the existence of multiple ligand dependent RyR activation mechanisms associated with distinct conformational changes.

Electron‐beam array lithography (EBAL) uses array optics to expose 108 to 1010 resolution elements without mechanical motion. The array optics are based on the use of a first stage of deflection (coarse deflection) which selects one of an array of lenslets. The lenslet array is followed by a second stage of deflection (fine deflection) which selects the final spot position. In order to maximize exposure rate and also minimize mechanical motion, it is proposed to use a 3×3 array of array optics channels to expose a 100 mm wafer. As a numerical example of the projected throughput of such a system consider a 20 MHz stepping rate per channel and 0.5 μm pixels. Then (3×1010 pixels)/(9×2×107 pixels per s) ≊170 s. Now if variable spot sizes and vector writing are used such that only 10% of the pattern is exposed using the smallest feature (pixel), the exposure time is reduced to ∠20 s. Consistent with these calculations, EBAL systems are presently under development with engineering goals of 0.5 μm smallest featu...


Nonlinear evolution of modulational instability by using the nonlinear Schrodinger equation in one dimension reveals a periodic reoccurrence of initial conditions. The nonlinear Schrodinger equation is the adiabatic limit of Zakharov equations, which couples the electrostatic electron plasma wave and ion-acoustic wave propagation. In the present paper nonlinear evolution of modulational instability is investigated by using one-dimensional Zakharov equations numerically. A simplified model is predicted that establishes the fact that the effect of relaxing the condition of adiabaticity is drastic on the nonlinear evolution patterns of modulational instability. These evolutions are quite sensitive to initial conditions, Fermi–Pasta–Ulam recurrence is broken up and a chaotic state develops. Next, quantitative methods like calculation of Lyapunov exponents and their variation with wave number is used to study spatial and temporally chaotic behavior. It is shown that regular patterns with a periodic sequence in space and time and spatiotemporal chaos with irregular localized patterns are formed in different regions of unstable wave numbers.


Matrix completion (MC) is a technique of recovering a low rank matrix from partial observed elements and their corresponding subset of the entries, which has been applied in synthetic aperture radar (SAR) and inverse synthetic aperture radar (ISAR) imaging for compressing the sampling data. It is effective for undersampled data with random echo elements missing, but will not work well for situation that there are some random rows and columns with none of entries observed because the echo matrix will not satisfy the required condition of MC. However, it is easier to operate in practical application for the latter way and it needs to store limited number of corresponding subset. Thus, a novel way of matrix rearrangement is proposed for ISAR data based on the characteristics of ISAR echo. The new matrix satisfies the condition of MC, and it has better low rank property while reduces the computational time compared with the existing methods of matrix rearrangement. The effectiveness of the proposed method can be demonstrated by the simulation and experimental results.

Learning-based image registration approaches typically learn to map from input images to a transformation matrix. Regarding the current deep-learning-based image rigid registration approaches learn a transformation matrix in a one-shot way. Our purpose is to present a deep reinforcement learning (DRL) based method for image registration to explicitly model the step-wise nature of the human registration process. We cast an image registration process as a Markov Decision Process (MDP) where actions are defined as global image adjustment operations. Then we train our proxy to learn the optimal action sequences to achieve a good registration. More specifically, we propose a DRL proxy incorporating an attention mechanism to address the challenge of large differences in appearance between images from different modalities. Registration experiments on 3D CT-MR image pairs of patients with nasopharyngeal carcinoma and on publicly available 3D PET-MR image pairs show that our approach significantly outperforms other methods, and achieves state-of-the-art performance in multi-m-modal medical image registration.


Since recent studies have shown that scientific misconduct is anything but a rare phenomenon, and given the harmful effects of such misconduct both for science itself and for the society at large, it is obvious that violations of integrity norms in scientific research should be taken seriously. The promotion of a culture of scientific integrity and the furthering of responsible research by their employees deserve a high priority within universities and research institutes. Proper disciplinary actions and preventive measures should be based on an analysis of the possible motives and causes underlying such misbehaviour. In this article three categories of causal factors are distinguished: Deceit as an individual vice, an existing culture of sloppiness and irresponsibility within certain disciplines or institutes, and the pernicious influence of today's research climate with its pressure for production and the 'metrification' of performance and output. Suggestions for dealing with cases of misconduct, resulting from these three distinct views, are presented and discussed.


Eleven species of Cyperaceae collected from central Nepal were karyomorphologically studied. Chromosome counts are reported for the first time to be 2n=42 for Carex cruciata, 2n=44 for C. cruenta, 2n=44 for C. fusiformis, 2n=44 for C. longipes var. nepalensis, 2n=44 for C. myosurus, n=14 for Isolepis setacea, and 2n=ca. 122 for Kobresia nepalensis. The chromosome counts of 2n=46 for C. remota and 2n=44 for Eleocharis kamtschatica are different from those presented in previous reports. The karyotypes of E. palustris (2n=16) and E. tetraquetra (2n=20) were the same as those presented in previous reports. One individual of E. palustris collected from Titigaon, Mustang District, showed 2n=15 chromosomes, which is considered to have been derived by fusion of 2 small chromosomes of the 2n=16 individual, forming one large chromosome.


The column, as an advanced fine coal cleaning equipment, has been developed for more than 20 years. The Microcel, Jameson cell and other types of columns have been used in the coal industry. Since 1990, the cyclonic micro-bubble flotation column has been developed. The test of 1.5 M packed column is underway in the Shitai coal preparation plant. Chinese fine coal is quite difficult to separate. Its native ash content is high and the floatability is difficult. There is not compressed air available in the small coal mine. The high cost for waste-water treatment limited the usage of wash water. It is necessary to study the column under Chinese conditions. Laboratory tests have been done for five coals. Conventional flotation tests were also done in a one-liter flotation cell in order to compare with the results of static column. Compared with a conventional flotation cell, lower ash content and higher combustion recovery are obtained from the static column. In addition, the static column can produce super-low-ash clean coal and treat very fine and high ash content slurry, which is difficult for conventional flotation cell to separate. Test results also show that the construction of the bubble generator and the aerationmore » rate are important for the performance of the static column. An one-meter diameter by six-meter high FXZ-1 static column has been used in four coal preparation plants for more than one year. The results are satisfactory. An additional three columns with the diameter of 1 M and 1.25 M in another 3 coal mines have been fabricated and will be put into use soon. The three-meter column has been designed for MaTou coal preparation plant and is in the course of fabrication now. The static column does not need any high-pressure air and usually does not use wash-water. The power consumption is very low and manual operation is easy. The investment and operating cost is low. In addition, the separation results are quite satisfactory. It has been recommended to be adopted in the coal preparation plants in China.« less


Studied is the influence of volume of hydrogen-air mixture, its composition and energy of its initiation on the formation of ignition centers before the front of spherical flame. During the experiments the mixture was placed into thin rubber envelopes of spherical shape having the initial volume of 7 and 40 m3. The mixture was initiated in the center of the reaction volume by the energy which was several times less than the critical energy of direct initiation of detonation. With increasing the initial volume of the mixture with the identical composition, registered is a decrease of the initiation energy at which the ignition centers before the front of spherical flame are formed.


In this letter, a high-resolution synthetic aperture radar (SAR) imaging algorithm based on a modified omega-K algorithm is proposed. The proposed algorithm first multiplies the reference signal. Then, the azimuth nonstationary phase error (ANSPE) is considered after performing the interpolation process based on the generalized frequency scale transformation. Finally, a well-focused SAR image can be obtained after compensating the ANSPE and correcting the residual spatial variant range migration by utilizing the range segmentation technique. The simulation results of point targets and the real-measured airborne high-resolution SAR data simultaneously verify the effectiveness and feasibility of the proposed algorithm.


Thiopurines and topoisomerase II‐targeted drugs (e.g., etoposide) are widely used anticancer drugs. However, topoisomerase II‐targeted drugs can cause acute myeloid leukemia, with the risk of this secondary leukemia linked to a genetic defect in thiopurine catabolism. Chronic thiopurines result in thioguanine substitution in DNA. The effect of these substitutions on DNA topoisomerase II activity is not known. Our goal was to determine whether deoxythioguanosine substitution alters DNA cleavage stabilized by human topoisomerase II. We studied four variations of a 40 mer oligonucleotide with a topoisomerase II cleavage site, each with a single deoxythioguanosine in a different position relative to the cleavage site (‐1 or +2 in the top and +2 or +4 in the bottom strand). Deoxythioguanosine substitution caused position‐dependent quantitative effects on cleavage. With the ‐ 1 or + 2 top and + 2 or+ 4 bottom substitutions, mean topoisomerase II‐induced cleavage was 0.6‐, 2.0‐, 1.1‐, and 3.3‐fold that with the wild‐type substrate (P=0.011, < 0.008, 0.51, and < 0.001, respectively). In the presence of 100 µ? etoposide, cleavage was enhanced for wild‐type and all thioguanosine‐modified substrates relative to no etoposide, with the + 4 bottom substitution showing greater etoposide‐induced cleavage than the wild‐type substrate (P=0.015). We conclude that thioguanine incorporation alters the DNA cleavage induced by topoisomerase II in the presence and absence of etoposide, providing new insights to the mechanism of thiopurine effect and on the leukemogenesis of thiopurines, with or without topoisomerase inhibitors.—Krynetskaia, N. F., Cai, X., Nitiss, J. L., Krynetski, E. Y., Relling, M. V. Thioguanine substitution alters DNA cleavage mediated by topoisomerase II. FASEB J. 14, 2339‐2344 (2000)


The high-resolution imaging spectroscopy remote sensing mission EnMAP (Environmental Mapping and Analysis Program, enmap.org) will cover the spectral range from 420 nm to 2450 nm with a spectral sampling distance varying between 4.8 nm and 12.0 nm. It will acquire 30 km in the across-track direction with a ground sampling distance of 30 m and the across-track tilt capability of 30° will enable a target revisit time of less than 4 days. The launch is scheduled for 2020. The high-quality products will be freely available to international scientific users for measuring and analyzing diagnostic parameters which describe vital processes on the Earth's surface. Based on the status of all segments of the mission the expected image product quality is analyzed and thereby it is illustrated how the requirements are met. The methodology relies on precise simulations of image acquisitions and the independently realized fully-automatic on-ground processing chain.


There has been considerable interest in surface-emitting laser diodes, because they are potentially very important for one- and two-dimensional monolithic laser arrays. There are several approaches to achieve surface-emitting lasers, such as (a) vertical resonator cavity [1], (b) 45° mirror [2], (c) parabolic mirror [3], and (d) grating-coupler [4-7]. Among them, grating-coupled lasers have the advantages of a narrow beam divergence and a dynamic single mode operation. However, the quantum efficiencies of grating-coupled lasers have been low. The maximum differential quantum efficiencies reported so far were 8% in distributed feedback (DFB) lasers [6] and 9% in distributed Bragg reflector (DBR) lasers [7]. In this paper, we report a three-stripe surface-emitting multiquantum well (MQW) DBR laser array with a very high differential quantum efficiency of 37% and a high output power of 500mW.


AIM: To investigate the SALL4 expression,proliferation and apoptosis in the LNCa P cells after transfection of SALL4 siRNA. METHODS: The expression of SALL4 at mRNA and protein levels was detected by realtime PCR and Western blotting. MTS assay,colony formation assay and flow cytometry were used to determine the proliferation,colony formation ability and apoptosis of the LNCa P cells. The effect of SALL4 on the expression of Bax and Bcl-2was analyzed by Western blotting. RESULTS: Compared with negative control group,the expression of SALL4 at mRNA and protein levels in LNCa P cells was down-regulated by transfection of SALL4 siRNA( P 0. 05). The proliferation rate and colony formation ability were decreased,while apoptosis rate increased in si-SALL4 group( P 0. 05). Higher expression of Bax and lower expression of Bcl-2 in si-SALL4 group were observed( P 0. 05). CONCLUSION: Down-regulation of SALL4 by siRNA not only suppresses LNCa P cell proliferation and colony formation,but also inhibits Bcl-2 expression and activates Bax expression to induce apoptosis.


The NSW Police Force Rural Crime Prevention Team (RCPT) was created to prevent, disrupt, and respond to crimes that impact specifically on the agricultural, pastoral and aquaculture industries. Since its inception in early 2018, the team has developed and delivered a number of novel and innovative policing initiatives which seek to make rural communities safer and increase their resilience. In this paper, we offer practical insights on a number of these developments. Specifically, we will examine innovations deployed in relation to rural policing across five key areas, including 1) investigating rural crime within New South Wales and identifying interstate links and trends; 2) identifying inhibitors within legislation and policy impacting the ability of Law Enforcement Agencies to prevent, disrupt and respond to rural crime; 3) enhancing the education and knowledge of Law Enforcement Officers regarding rural crime; 4) raising the public awareness of rural crime and increasing community engagement with relevant stakeholders within rural communities and industries; and, finally, 5) collaborating and engaging with academic research/higher education toward the shared goal of safe rural spaces. We conclude the paper by discussing these practical developments in the context of farm crime research and, more specifically, how these collective efforts may serve to address established limitations and gaps in the policing and prevention of crime in rural spaces.


Recent studies in industrialized countries have shown that equivalence scales are income-dependent. We investigate whether this dependence also holds in poorer, services oriented countries, by considering the case of Cyprus. We also examine whether household economies of scale and relative children costs differ from those found for industrialized countries.


The function f(x) may be given explicitly as, for example, a polynomial or a transcendental function. Frequently, however, f(x) may be known only implicitly in that only a rule for evaluating it on any argument is known. In rare cases it may be possible to obtain the exact roots such as in the case of a factorizable polynomial. In general, however, we can hope to obtain only approximate values of the roots, relying on some computational techniques to produce the approximation. In this lecture, we will introduce some elementary iterative methods for finding a root of equation (1), in other words, a zero of f(x).


This paper describes a system for handwritten Chinese text recognition integrating language model. On a text line image, the system generates character segmentation and word segmentation candidates, and the candidate paths are evaluated by character recognition scores and language model. The optimal path, giving segmentation and recognition result, is found using a pruned dynamic programming search method. We evaluate various language models, including the character-based n-gram, word-based n-gram, and hybrid n-gram models. Experimental results on the HIT-HW database show that the language models improve the recognition performance remarkably.


This article first introduces the theoretical basis and concepts related to cold chain logistics of agricultural products, analyzes the cold chain logistics market of agricultural products and the necessity of developing cold chain logistics, and then finds that there is a lack of overall planning for cold chain logistics of agricultural products. Subsequently, it carried out the "Internet +"-based agricultural product cold chain logistics system planning and based on agricultural product development logistics' actual situation, and it gave cold chain system optimization suggestions. Finally, a cold chain logistics enterprise for agricultural products is used to construct a cold chain logistics system for agricultural products, including business models, information platforms, and system functions.


The present paper analyzes scientific research studies on the familiarization of children at pre-school age with the natural environment to the effect of forming an appreciative attitude to nature as a cultural value. The basic structural components of the concept are outlined: the cognitive, the affective, and the behavioural one. Arguments from the theory and practice of education have been advanced which prove the necessity for developing a theoretical model of pedagogical intervention for the formation of an appreciative attitude to nature as a cultural value.


The utility model discloses a self-lubricating corrosion-resistant and eccentric wear-resistant oil pipe, which is applied to an oil field production well. The self-lubricating corrosion-resistant and eccentric wear-resistant oil pipe mainly comprises an oil pipe and a self-lubricating corrosion-resistant and eccentric wear-resistant coating, wherein the self-lubricating corrosion-resistant and eccentric wear-resistant coating is formed on the inner wall of the oil pipe through electrostatic spraying, is uniformly sprayed on the inner wall of the oil pipe and has thickness of 500-800 microns. The oil pipe has the effects that: the self-lubricating corrosion-resistant and eccentric wear-resistant coating has high self-lubrication, corrosion resistance and wear resistance, superior thermal resistance and high wear resistance at high temperature, can be used at the well temperature of less than 150 DEG C, has high adhesion and strong chemical stability, and does not fall off in flakes; and the mechanical strength and the application performance are not influenced.


The following notes are intended to make a small digression on the topics mentioned in the title of the same, since these were not addressed in the past tribute by the Institute of Physics of the UdeA. We believe more than platitude try to justify the importance and effectiveness in the development of mathematics and physics during the eighteenth century and present such issues, therefore a brief description of the methods and problems attacked by Euler and his contemporaries using the heuristics. Note in advance that they constitute a strong impoverished attempt to honor the memory of who is considered the Shakespeare of Mathematics: Universal, rich in detail and inexhaustible.


In this article I aim to rise to the bait thrown my way by Greta Olson where she posits ( From Law and Literature to Legality and Affect, p.121) that law-and-affect scholarship is anti-narrative, and provocatively imagines that I would shake my head and chuckle, asking what one is to do with the questions asked by scholarship on emotion and affect in actual legal practice. As one spending most of her time in judicial practice I am not only firmly convinced of the importance of narrative in law, what is more, I often have to steep myself in the legal effects of emotion and affect and ask what consequences they should have for the people involved. I will therefore consider the trial as a performance, i.e., a show trial in the positive sense that as a performance shows and tells that it has read well what is brought before the court.

All developed countries have been struggling with a trend toward health care absorbing an ever-larger fraction of government and private budgets. Adopting any treatment that improves health outcomes, no matter what the cost, can worsen allocative inefficiency by paying dearly for small health gains. One potential solution is to rely more heavily on studies of the costs and effectiveness of new technologies in an effort to ensure that new spending is justified by a commensurate gain in consumer benefits. But not everyone is a fan of such studies and we discuss the merits of comparative effectiveness studies and its cousin, cost-effectiveness analysis. We argue that effectiveness research can generate some moderating effects on cost growth in healthcare if such research can be used to nudge patients away from less-effective therapies, whether through improved decision making or by encouraging beefed-up copayments for cost-ineffective procedures. More promising still for reducing growth is the use of a cost-effectiveness framework to better understand where the real savings lie—and the real savings may well lie in figuring out the complex interaction and fragmentation of healthcare systems.

One approach to securing radio signals in wireless sensor networks is frequency hopping in which transmitters and receivers change frequencies at a predetermined interval using a pattern of frequencies that is programmed a priori or calculated dynamically via ashared seeding mechanism. For these systems, if an adversary can physically capture a node in the network and steal the seed or hopping set, it can compromise the network. To protect against this weakness, we propose Signal Strength Seed Frequency Hopping, a hopping set selection scheme in which the seed used to calculate a dynamic hopping set is generated using signal strength measurements collected after the network has been deployed. We show our scheme has sufficient stochasticity to produce hopping sets that cannot be easily reproduced by an adversary.


The pretraining model has the problems of large number of parameters, complex structure, and difficult to be compressed into a small model with both performance in practical deployment. Aiming at the above problems, this paper proposes a lightweight entity recognition model with good performance by using the framework of knowledge distillation to supervise and guide the student entity recognition model through the teacher entity recognition model. Finally, the feasibility and effectiveness of the method proposed in this chapter are verified by experiments.


Out-wintering beef cattle has several potential advantages over housing but these have to be very carefully weighed against possible concerns over cow welfare during severe weather and under unsuitable field conditions. Out-wintering really only applies to adult beef cows calving in the spring. Young calves and store cattle should only be outwintered if they are in areas of the UK which have reliably mild winter weather conditions.


Massive perivillous fibrin deposition (MPFD) and maternal floor infarction (MFI) are rare and poorly understood placental lesions often leading to preterm delivery, intrauterine fetal growth restriction (IUGR), and fetal death. An association between MPFD and thrombophilia has been reported. Here, we report two cases in which MPFD followed a previous uncomplicated term pregnancy. MPFD was diagnosed on the basis of standard criteria (transmural fibrinoid deposition).
Case 1 was a 33-year-old woman who presented with IUGR at 21 weeks; intrauterine fetal death occurred at 25 weeks.
Case 2, a 32-year-old woman, noted reduced fetal movements and was diagnosed with IUGR at 29 weeks. Despite immediate cesarean section, the newborn survived for just a few days. Autopsy showed no abnormalities in either fetus.
Placental histology showed villi (>60% of placental mass in both cases) entrapped by large amounts of deposited fibrinoid material. Neither woman had a medical history of autoimmune disease or any blood coagulation disorder. Complete thrombophilia screening was not performed.
Our data show that MPFD may occur in women after a previous normal term pregnancy. Given the high reported recurrence rate (~50%) of this placental pathology, further pregnancies should be considered at risk of MPFD. Women should be tested for thrombophilia in order to improve the management and fetal outcome of subsequent pregnancies


We propose a method for merging soil moisture retrievals from spaceborne active and passive microwave instruments based on weighted averaging taking into account the error characteristics of the individual data sets. The merging scheme is parameterized using error variance estimates obtained from using triple collocation analysis (TCA). In regions where TCA is deemed unreliable, we use correlation significance levels (<inline-formula> <tex-math notation="LaTeX">$p$ </tex-math></inline-formula>-values) as indicator for retrieval quality to decide whether to use active data only, passive data only, or an unweighted average. We apply the proposed merging scheme to active retrievals from advanced scatterometer and passive retrievals from the Advanced Microwave Scanning Radiometer—Earth Observing System using Global Land Data Assimilation System-Noah to complement the triplet required for TCA. The merged time series is evaluated against soil moisture estimates from ERA-Interim/Land and <italic>in situ</italic> measurements from the International Soil Moisture Network using the European Space Agency's (ESA's) current Climate Change Initiative—Soil Moisture (ESA CCI SM) product version v02.3 as benchmark merging scheme. Results show that the <inline-formula> <tex-math notation="LaTeX">$p$ </tex-math></inline-formula>-value classification provides a robust basis for decisions regarding using either active or passive data alone, or an unweighted average in cases where relative weights cannot be estimated reliably, and that the weights estimated from TCA in almost all cases outperform the ternary decision upon which the ESA CCI SM v02.3 is based. The proposed method forms the basis for the new ESA CCI SM product version v03.x and higher.


In the last few years, multicasting is increasingly used as an efficient communication mechanism for group-oriented applications in the Internet. Some multicast applications require confidentiality for transmitted data. So, a traffic encryption key is used to assure this confidentiality and has to be changed and distributed to all valid members whenever a membership change (join or leave) occurs in the group. The bandwidth used for re-keying operations could be high when the group size is large. To cope with this limitation, many solutions propose to organize group members into subgroups that use independent traffic encryption keys in order to mitigate the scope of key management and thereby to scale better to large groups. Unfortunately, these solutions require the decryption and re-encryption of multicast messages whenever they pass from one subgroup to another. Moreover, the decryption/re-encryption operations induce delays in packet delivery throughout the delivery path. In order to avoid delays in packet delivery and perturbations caused by re-keying, we propose in this paper an adaptive solution for key management which organizes group members into dynamic and homogeneous clusters according to the application level requirements. First, we show that partitioning the group into clusters of subgroups that use independent traffic encryption keys can be formulated as tree partitioning problem. Then, we propose a protocol to solve the problem with respect to the application requirements and membership behavior. We conducted several simulations of the proposed protocol and the obtained results show that our solution is efficient and achieves better performance trade-offs compared to other schemes.


For the identification of cashmere,the statistical regularities of scale pattern genetic code under optical microscope are studied. These results show that fiber diameter is even and its coefficient of variation is smaller than that of other scale pattern gene codes. Among all scale pattern gene codes,the optimal fitting of scale rectangle factor follows normal distribution and that of all other shape parameters follow lognormal distribution with a correlation higher than 0. 99. Further comparisons show that among all scale pattern gene codes,the dispersion of relative shape parameters is smaller than that of absolute shape parameters. The dispersion in scale rectangle factor is smallest and largest in scale area. Scale looks more like a square or narrow rectangle.


The addition of PHA-stimulated human lymphocytes inhibits the continued proliferation of autologous lymphocytes growing in a feeder-layer system in response to mitogen. Velocity sedimentation and 3HTdR autoradiographic studies of the suppressive population indicated that the effect is mediated by proliferating, large cells ("blasts"). Other populations of actively dividing cells, including normal lymphocytes stimulated with pokeweed mitogen or the calcium ionophore A23187, the Raji B cell line, and human and mouse fibroblasts, suppressed 3HTdR uptake as well, in a similar dose range. The suppressive effect of these cells could be roughly correlated with the proportion of blasts in the cell population.
 Inhibitory activity in this system was not demonstrated in supernatants from PHA blasts compared to saline controls, but intact cells suppressed across a nucleopore membrane but not a dialysis membrane. Supplementing the assay culture with low m.w. constituents of the medium did not decrease the suppressive effect. However, when fresh serum was added in increasing concentrations with the inhibitory cells, their suppressive effect was partially abrogated.
 These results may be interpreted in at least two ways that are not mutually exclusive: i) PHA blasts may elaborate a labile inhibitory substance that may be bound, inactivated, or degraded to some degree by serum and/or ii) actively proliferating cells may exhaust an essential high m.w. nutrient in the assay culture. It is likely that the inhibitory effects observed in many culture systems involving mitogen-induced suppressor lymphocytes are not restricted to immunologic phenomena but may include a more general function of actively dividing cells, which is neither tissue nor species specific.


Partition coefficients, as values of log P, between water and two room-temperature ionic liquids and between water and an aqueous biphasic system have been correlated with Abraham's solute descriptors to yield linear free energy relationships that can be used to predict further values of log P, to ascertain the solute properties that lead to increased or decreased log P values, and to characterize the partition systems. It is shown that, in all three of the systems, an increase in solute hydrogen-bond basicity leads to a decrease in log P and an increase in solute volume leads to an increase in log P. For the two ionic liquid systems, an increase in solute hydrogen-bond acidity similarly decreases log P, but for the aqueous biphasic system, solute hydrogen-bond acidity has no effect on log P. These effects are rather smaller than those observed in traditional water−solvent systems. However, the ionic liquids appear to have an increased affinity for polyaromatic hydrocarbons as compared to traditional orga...


Electrical load forecasting for buildings plays a key role in the smart-grid paradigm, since accurate forecasts help in efficient energy management. This paper presents a practical solution, which can be readily deployed, by considering various real-life issues. Load forecasting algorithms are developed using Non-linear AutoRegressive model with eXogenous input (NARX) neural network and Support Vector Regression (SVR) to forecast the power consumption for day ahead, week ahead and month ahead at 15 minute granularity. Missing values, outliers in the power consumption data are treated using simple but effective techniques based on the thorough understanding of the power consumption time-series data. Autoregressive features, temperature and some efficacious contextual information, which are completely pertinent to this problem, are being derived to model this heterogeneous time series that consists of disparate patterns on weekdays, weekends and holidays. The novelty of the solution lies in the fact that it extensively models all the variations and produces accurate long term predictions at high granularity (15 min). The algorithms are validated using the actual power consumption data from three Office buildings; forecasting accuracy of both SVR and NARX neural network are comparable, the latter performs better by a thin margin. The average forecasting accuracy is nearly 93%, 88–90% and 85–87% for day ahead, week ahead and month ahead forecasting respectively.


Abstract This paper intends to provide a short assessment on how Marx and Weber approached social inequality. The assessment is conducted using evolutionary rationality. Even though Marx and Weber had seemingly contrasting approaches, I argue that in reality both are complementary and can be better understood using Darwinian evolutionary theory or "Universal Darwinism" as the locus in which the two rationalities described formation processes based on competition for the survival of social forces and the crafting of adaptive and advantageous strategies that allow for the synchronic and diachronic reproduction of social groups.


PURPOSE: To improve traveling stability and riding comfort of a road surface traveling vehicle by furnishing a stationary cover made of a non-magnetic material with a sensor coil, providing a permanent magnet on the guiding closed side on a free end of a damper cylinder and providing an evaluation circuit. CONSTITUTION: A vibration damper is connected to a wheel mass by a connecting member 4, and a piston rod 2 is connected to a car body mass through a fixed member. The rod 2 passes through a guiding closed member 36, a permanent magnet 10 is fixed on the member 36, a cover 35 made of a non-magnetic material is fixed on the rod 2 through a connecting means 19 and a sensor coil 8 is buried in it outside of a damper cylinder 1. When the cylinder 1 is pushed up by a non-planar property of a road surface, the magnet 10 moves upward in the coil 8, and voltage in proportion to speed is induced in the coil 8. This induced voltage is transmitted to a filter 20 through a connecting line 12, supplied to a microprocessor 28, and this evaluation circuit eliminates work of the vibration damper and prevents transmission to the car body mass.


Objective: The aim of this study was to observe the effects of 5- aza- 2'– deoxycytidine on the DNMTs expression in nerval cell line NG108- 15 which repeatedly exposed to autoprogressive hypoxia and to investigate the possible neuroprotection mechanism in it. Methods: NG108- 15 cells were divided into 5- aza- cdR( 10. 0 μmol / L) group and control group. Each group were treated with hypoxic( H),hypoxic preconditioning( HP) and no hypoxia( C). The mRNA levels of DNMTs were analyzed by QPCR. Results: DNMT1 was not found difference between 5- aza- cdR treatment group and control group. Hypoxia preconditioning treatment can change the expression of DNMT3 A and DNMT3 B in control group. The DNMT3 A mRNA of HP group( P 0. 05 vs H) and the DNMT3 B mRNA of HP( P 0. 05 vs C) in control group. DNMT3 B mRNA of H was found to be decreased in 5- aza- cdR( P 0. 05 vs H and C); DNMT3 B mRNA of HP was different between the 5- aza- cdR group and control group( P 0. 05). Conclusion: Hypoxic preconditioning can change the expression of DNMT3 A and DNMT3 B mRNA. Hypoxic preconditioning combined with 5- aza- cdR can affect the expreesion of DNMT3 B mRNA.


A new catalyst system is developed for regiocontrolled synthesis of poly(2,5-dialkyl-1,4-phenylene oxide)s by oxidative coupling polymerization of 2,5-dialkylphenol. The treatment of the α-benzoin oxime with manganese chloride in methanol under basic condition led to the formation of manganese benziloxime complex in which α-benzoin oxime was converted to benziloxime and coordinated to manganese as bidentate ligands. The polymerizations were conducted in toluene using manganese benziloxime complex and dibutylamine in a continuous flow of oxygen, and the structures, properties of the catalyst, and polymers were studied by nuclear magnetic resonance spectroscopy (NMR), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and gel permeation chromatography (GPC). The catalyst showed high regioselectivity and reasonably good yields to afford the poly(2,5-dimethyl-1,4-phenylene oxide)s with 1,4-C-O linkage structure which possessed melting point higher than the poly(p-phenylene sulfide) or type II liquid crystalline polymer. The regioselectivity was enhanced when employing molecular sieves-supported manganese catalyst system at 90°C and the crystallinity of poly(2,5-dimethyl-1,4-phenylene oxide)s was estimated by wide-angle X-ray scattering (WAXS) and DSC. The crystallinity was calculated about 23.7% and a heat-reversible melting and crystallization behavior occurred at 327.8 and 306.8°C, respectively. © 2008 Wiley Periodicals, Inc.

APP,PER,MEL and Al(OH)3 were selected as non-halogen flame-retardant additives for polypropylene(PP).The effect of the flame-retardant on the impact strength,melt flow rate, thermal properties, and combustion characteristics of PP were studied by orthogonal design.The results showed that polyammonium phosphate (APP),pentaerythritol (PER),MEL and Al(OH)3 had good synergistic flame-retardant effect on PP,and PP had good combination property when the proportion of PP to flame retardant were PP/APP/PER/MEL/Al(OH)3=100∶30∶10∶3∶5,and the oxygen index of PP reached as high as 32.1 %.


Abstract This article deals with the process of community structuring in a section of the Hispanic Caribbean population living on the margins of society due to its socioeconomic status as well as its sexual tendencies. It also analyses the development of a series of strategies that will give the individuals belonging to those groups the possibility of accepting their historical origins, and their social and sexual identities. One of the main strategies is to control the economic system that gave rise to them in the first place: capitalism. Mastering the rules of the system, knowing the name of the game, helps them acquire a knowledge and awareness of who they are, and makes it easier for them to generate small entrepreneurial projects. The capacity to understand and to take part in the economic system allows them to achieve a new and positive identity, which will in turn redefine them as members of their minority group.


Conceptual modeling is important for developing databases that maintain the integrity and quality of stored information. However, classical conceptual models have often been assumed to work on well-maintained and high-quality data. With the advancement and expansion of data science, it is no longer the case. The need to model and store data has emerged for settings with lower data quality, which creates the need to update and augment conceptual models to represent lower-quality data. In this paper, we focus on the intersection between data completeness (an important aspect of data quality) and complex class semantics (where a complex class entity represents information that spans more than one simple class entity). We propose a new disaggregation construct to allow the modeling of incomplete information. We demonstrate the use of our disaggregation construct for diverse modeling problems and discuss the anomalies that could occur without this construct. We provide formal definitions and thorough comparisons between various types of complex constructs to guide future application and prove the unique interpretation of our newly proposed disaggregation construct.

The utility model discloses a light emitting diode (LED) columnar lamp of a heat-dissipating lamp bracket, and aims to provide an LED columnar lamp of a heat-dissipating lamp bracket, which has the advantages of good heat-dissipating effect, reasonable structure, convenient manufacture, long service life and good lighting effect. The utility model comprises a columnar lamp bracket; a lamp cap with a socket or a screw socket is connected to the back end of the columnar lamp bracket; and an LED which is arranged in a circumferential direction is mounted on the surface of the outer side of the columnar lamp bracket and communicated with a corresponding contact terminal on the lamp cap through a conducting wire. The LED columnar lamp is characterized in that the columnar lamp bracket is made of an aluminum alloy; and a lamp shade made of transparent plastics is mounted in the front of the LED. After the lamp shade made of the transparent plastics is mounted in the front of the LED, light rays look soft, the LED is difficultly damaged due to the protection of the lamp shade, and the heat in the lamp shade can be quickly released from the outer surface of the lamp bracket through the conduction of the aluminum alloy, thereby effectively reducing the temperature in the LED columnar lamp. Furthermore, the utility model has the advantages that the service life of the LED columnar lamp is prolonged.


Objective To observe the primary clinical results of Gore (R) Viabahn endoprosthesis for atherosclerotic stenosis or occlusion in superficial femoral artery (SFA).Methods From March 2013 to November 2013,45 consecutive patients (54 limbs) who had ischemic symptom due to stenosis or occlusion of superficial femoral artery were treated by endovascular deployment of Gore (R) Viabahn endoprosthesis.We observed patency rate,improvement of Rutherford classification and ankle-brachial index,limb salvage rate and survival rate after 1,3 and 6 months.Results 43 patients (52 limbs)were followed-up,among which 32 patients(38 limbs)belonged to TASC Ⅱ type C or type D lesion.The mean (± SD) length of treated segment in 52 limbs was(19 ±4)cm.The rate of postoperative patency on duplex ultrasonography:one month,3 months and 6 months were 96.15% (50 limbs),92.31% (48 limbs)and 90.38% (47 limbs) ; Ankle-brachial index increased from(0.32 ±0.20)to(0.68 ±0.18) (t =3.180,P < 0.005) after 6 months ; at 6 months limb salvage rate was 96.08 percent (49 limbs),and survival rate was 97.67% (42 patients).Conclusions Implantation of Gore (R) Viabahn endoprosthesis in atherosclerotic stenotic or occluded superficial femoral artery safely achieves a definite primary clinical effectiveness.

Hot water supply of 85℃ is needed to bottle washer in the beer brewing process (Kalogirou, 2003). For this purpose it is more appropriate to choose an evacuated tubular solar collector (ETSC) system rather than the flat plate types which are mostly used to produce water temperatures around 60℃ for domestic use (KIER Report, 2004; Kalogirou, 2004; Niemann et al., 1997). In the present study, simulation was performed through the system modeling for the process heat system installed in beer brewery of Gwangju Korea. Simulation model of TRNSYS was confirmed first, and four days of examination period from August 8 to 11 at year 2003 were taken. Here it can be observed that analysis results are in good agreement with experimental data. Full one year simulation was conducted for the prediction of long term performance of ETSC system in Gwangju. The system was analyzed with TRNSYS using the hourly weather data of the Gwangju. And additional simulations were conducted for one year term under the weather conditions of four locations as Daejeon, Busan, Seoul, and Daegu as well. Based on these TRNSYS simulations, long term thermal performance of the ETSC system has been predicted for various weather conditions. The system efficiency and heat transfer rate by hot water supply were obtained, and their effects on the long term performance of the system were compared and analyzed.


Philip Roeder is one of the leading scholars studying secessionist movements, and he has been at the forefront of this research for many decades. In his previous work, he emphasized that ethnic minorities whose leaders control a substate—a province, for example—are more prone to develop secessionist movements because they have the institutional resources to do so. This often leads to violent confrontations with the center, and many new nation-states originate from such movements (Where Nation-States Come From: Institutional Change in the Age of Nationalism, 2007). Roeder's new book builds on these insights but also takes the analysis in a new direction. Overall, I find the theory proposed in National Secession exciting and promising, but was somewhat disappointed by how it was empirically specified and tested. The theory moves away from structuralist accounts that dominate the study of secessionist movements. Previous scholarship related these movements to memories of previous independent statehood, to political exclusion from central-level government, to geographic settlement patterns, and so on. Instead, Roeder's theory focuses on the leadership of secessionist movements and their strategic decisions. Taking as a model Lenin's advice on how to build a successful revolutionary movement, Roeder outlines the challenges that secessionist leaders face and how best to overcome them. Most importantly, they must convince rank-and-file members of a would-be nation that their national identity is indeed the most salient form of collective identification, that the current lack of independence has negative consequences for all of them, and so forth. Propaganda that links many different individual concerns, including material ones, to the problem of political dependency and promises a bright future in a new nation-state is therefore crucial. Too close an association with the concerns of a particular group of co-nationals is to be avoided, and strict ideological linkages between national independence and as many grievances as possible need to be established, thus building a large coalition centered around the nationalist agenda. Leaders also must recruit a group of dedicated cadres who are willing to sacrifice their lives to the cause and can endure and survive harsh setbacks. They need to keep the movement united and avoid defections and factionalism by providing or promising incentives, both ideological and material. Finally, leaders must encourage, channel, and at the same time control activists who take pleasure in marching in protest, attacking police officers, or throwing bombs. For Roeder, skilled leadership that excels in these three tasks is the sine qua non in getting an independence project off the ground and pushing it onto the national and international political agenda. Focusing on the post-1945 world, he shows that most independence movements did not achieve their goal by prevailing on the battlefield. Much more often, they were able to create a new nation-state with the help of international (mostly Western) support or because the central government collapsed (as was the case in the Soviet Union) or was simply no longer interested in dealing with an annoying independence movement (leading to the independence of Singapore and Slovakia). Because independence leaders know this history, they keep their campaigns alive even when they have minimal chances to win the armed battle, waiting for an opportunity to arise that will allow them to declare and maintain independence. Violence is therefore more often symbolic, meant to encourage supporters by providing examples of heroic dedication rather than to actually win the battle militarily. Because state sovereignty is a zerosum-game, which reduces the inclination of central elites to compromise, most of these conflicts then become entrenched, difficult to solve, and very long-lasting. Roeder's focus on leadership represents a bold and innovative move in a literature that is very heavily tilted toward macro-structuralist accounts (as is perhaps characteristic of political science in general, but see James Read and Ian Shapiro, "Transforming Power Relationships: Leadership, Risk, and Hope," American Political Science Review 108 [1], 2014). I wish, however, that Roeder had connected his arguments to the vast literature on social movements in political sociology, where many scholars have worked on similar problems; for example, "frame resonance" was identified as a crucial mechanism to understand how movement propaganda works (see David


The influence of humic acids on Pisum sativum L. seed swelling process was studied. Humic acids (HA) were applied during seed swelling by watering the seeds for one hour in the first, fourth and eight hour of the process. Three different concentrations of HA 0.005 [gC dm-3]; 0.01 [gC dm-3]; 0.02 [gC dm-3] in buffer phosphate solution at pH=6.5 were used. The control sample was the pea seeds watered in buffer phosphate solution at pH=6.5 without humic acids. All of the pea seeds were placed on Petri dishes onto full water capacity filter paper. Humic acids at concentration 0.02 [gC dm-3] increased the fresh mass of swelling seeds when applied in the first hour of experiment. It was also noted that all concentrations of humic acids applied in the  first hour of experiment increased the percentage of pea seeds with visible radicle at the end of experiment.


Background. Networks are scenarios for coordination and joint, affections, love and hate among actors who are part of them. The actors are mediated by interests according to their contexts and experiences. Objective. To show the learning experienced during the process of leading the network of Community Based Rehabilitation (CBR) in the Americas based on the principles of Jose Bernardo Toro. Development of the subject. Three stages in our experience were identified. First, setting up the network; second, living the network, and third, recovering the learning derived from it. The article includes an overview of the structure of RBC networks in the world and a description of the networks that are consolidated around disability in the Americas. This with purpose of reflectinf on both network work and teamwork. Conclusions. The learning experienced, in the last three years, is related to learning not to attack the congener, communicating, interacting, and deciding as a group and to value social knowledge. Finally, some recommendations on the way forward are provided.


Cotton (Gossypium hirsutum L.) is an important cash crop in Zambia. The national seed cotton yield (SCY) per hectare ranges from 200-500 kg/ ha as compared to the potential of up to 2500 kg/ ha. Understanding the specific performance of several genotypes across different environments is an option, which may maximize specific genotypic performance. In addition, the performance of specific environments if known concerning specific and mean genotypic performance may guide the breeding approaches to these environments. This study therefore investigated the presence of SCY mega-production environments in Zambia and delineated the environments and identified the ideal test environment capable of discriminating yield differences among genotypes. Thirty (30) genotypes, were planted following a 6 x 5 lattice design with three replications in seven environments of Zambia. Additive main effects and multiplicative interaction (AMMI) model and genotype plus genotype by environment (GGE) biplot were used to explore the genotype by genotypic environmental interaction (GEI). Three mega environments (M1, M2 and M3) were identified. Genotype G27, G26 and G28 were the best performing genotypes in M1, M2 and M3 with overall mean SCY of 1416, 1320 and 960 kg/ ha respectively. Among the locations, Masumba was identified as an ideal test environment with mean SCY of 1249 kg/ ha. Therefore, testing seed cotton genotypic yield and selecting desirable genotypes in Masumba may be sufficient for evaluation.


In many textbooks of Thermodynamics and Statistical Physics is asserted that a real gas carrying out a free adiabatic expansion always is cooled. As a typical example of this behavior, the expansion of a van der Waals gas is mentioned. And in fact, this is true for such a gas, due to its intermolecular potential, which is of the hard spheres type. Nevertheless, Roulet and Goussard [5], in 1993, showed that, such as occurs in the Joule-Kelvin expansion (process of strangulation), a real gas in free adiabatic expansion, can be cooled or heated, depending on the nature of the intermolecular potential in which the corresponding equation of state is based. In this thesis, diverse intermolecular potentials are explored, finding that there are some, for which an inversion temperature Ti exists. If the initial temperature of the gas in expansion is smaller than Ti cooling occurs and if it is larger than Ti warming occurs. The causes of this behavior are also discussed.


Cathodic polarization curves were determined when surfactant was used singly or mixed with others under the condition of pH=2.3 at room temperature. The results show that chemicals such as sodium diphenylaminesulfonate, rhodamine B, sodium citrate, methyl naphthylamine and sodium selenite could obviously cause movement of the polarization curves in the negative direction if the scanning electriode potential was lower than -0.85V, indicating that they had an obvious anti-hydrogen effect.


Abstract : The research conducted in this project demonstrated that TNT can be removed effectively by native soil bacteria via a co-metabolic process. The aerobic bacterial consoflium developed from the TNT-contaminated soil successfully removed TNT in liquid cultures. Various co-substrates (glucose. succinate, acetate. malate, citrate. and molasses) were studied and evaluated. Among these. molasses was identified as the best substrate for TNT removal. Aerobic optimization studies revealed that a pH of 7.0. a temperature of 22-24 deg C. and an ammonium concentration of 0.5 g/L are optimal for degradation of TNT by the bacterial consoflium. The successful operation of an aerobiclanoxic laboratory-scale soil slurry reactor showed that contaminated soil could be treated. Batch treatment resulted in 100% removal of TNT within 21 days. Semicontinuous treatment also resulted in complete degradation of TNT.

Result of observations and interviews with several informants indicate that this hospital still has a low service quality and customer satisfaction have not been optimally viewed from the dimensions of service quality. Quality improvement and quality of these services should be started from a strong commitment and high professionalism that existing systems can run optimally so as to achieve customer satisfaction.


The town Cleves (in German, Kleve) is a small county town on the Dutch border. The town was almost completely destroyed during the Second World War. Since then it has been rebuilt and today it is, once again, the bustling economic and administrative centre of the surrounding rural area.


In robust M estimations for linear regression models, median absolute deviation often used as the scale parameter estimator. In this paper, we introduce another robust scale estimation originally proposed by Rousseeuw under univariate situation into linear regression. Some property about this scale estimation is mentioned and a limited Monte Carlo study conducted. It shows that this robust scale estimation can enhance the estimate efficiency of regression coefficients for Huber′s M estimators.


Transductive support vector machine (SVM) is to construct theoretical frame for recognizing specifically unlabelling sample based on labelling sample effectively. Compared to traditional inductive SVM, transductive SVM is more economical, and has more perfect classification ability. However, fatal shortcoming of transductive SVM consumes a great deal of training time.Therefore,training algorithm was proposed for transductive SVM based on incremental learning. That was,the set of sample for next interative training was made of two part: sample of support vector got from currently interative training and some testing sample enduced with label newly.The aim was to reduce training sample and save training time.At the same time, the method of pair labelling and back searching operation according to mistakenly classified testing sample were applied in the course of training to guarantee that the traning algorithm was convergent and had high precision of classification. Practical result of state judgement proves the method is valid.

As a nontoxic substitute for mercury electrodes, bismuth electrodes attained a lot of attention during the last years. In this report we describe for the first time the preparation of two different directly heatable bismuth-modified microwire electrodes. We characterized the electrochemical behaviour using cyclic voltammetry in acetate buffer and alkaline tartrate solution. The bismuth electrodes show a significantly wider potential window compared with bare gold wires. In the presence of picric acid as one example for the detection of explosives, the bismuth electrodes deliver higher signals. By applying heat during the measurements, the signals can be enhanced further. We used the temperature pulse amperometry (TPA) technique to improve the electrochemical response at the different types of electrodes. In this preliminary study, we were able to detect 3 ppm traces of picric acid.


Erin Labbie, Advisor "Encountering Cannibalism: A Cultural History" explores the relationship between the trope of cannibalism and the notions of civilization and savagery. This thesis intervenes in scholarship on cannibalism by analyzing the surrounding discourses from a cultural studies position. Despite the advancements in scholarship in the past fifty years that have seen the breakdown of many binary systems, criticism that addresses cannibalism continues to perpetuate the civilization/savagery binary. Working from a meta-discursive position in American Culture Studies, my thesis interrogates the history of cannibalism in order to understand this stubborn persistence of the civilization/savagery binary in studies of cannibalism across other disciplines. Tracing the development of cannibal discourse, we discover the place of the cannibal within a fantasy of wholeness of American identity. The cannibal is both a disruption of civilization and a foundational element as neither civilization nor savagery can exist independently. The trope of cannibalism allows the scholar to make connections and draw conclusions across disciplines, time periods, and theoretical positionings, and provides a unique entry point for discussions of race and gender. Chapter I: Encountering Cannibalism explores the development of cannibal discourse. In order to understand the discursive development of the cannibal, one must first interrogate European understandings of civilization and savagery. The early writers of the New World


Based on the analysis of the mechanism and the reason of the residual stresses in injection molding process, CAE software was used to simulate experimental approach to study the effect of different molding condition on the residual stresses in PS injection molded part.The gapwise profile of the residual stresses and solidification pressure were obtained from the simulation results.The results showed that the gapwise distribution of residual stresses was tensile-compressive-tensile (surface layer-sub surface layer-mid layer).The residual stresses increased with the rise of the melt temperature and the increase of the holding pressure,while the solidification pressure was an dominate influence factor on the gapwise residual stresses distribution.


Techniques are provided for establishment of multiple concurrent virtual networks. In one example, there is provided a method operable by a virtual network controller (VNC) or the like. The method may involve establishing communication links with a plurality of virtual network interfaces (VNIs) operatively coupled to a plurality of virtual networks. The method may involve establishing a single port communication link with an operating system. The method may involve allowing the virtual networks to be transported on top of a physical network, and facilitating communication between the operating system and the virtual networks via the single port communication link.


The infrared spectrum of diaqua tetra- m - formato dichromium (II) complex has been obtained in the frequency range 4000 to 400cm-1. A normal coordinate treatment performed on the 1:1 model of the complex gives calculated frequencies in good agreement with the observed ones. In order to assign bands and to see the coupling between various vibrational modes, the potential energy distribution in each normal vibration was calculated with respect to each symmetry coordinate for all the in-plane vibrations. The results show that in spite of the effect of coordination some of the formate ligand based vibrational modes remain localized, though others such as nas(COO) and ds(HCO) couple strongly with ring deformation. The analysis also indicate that bands at 464, 537 and 540 cm-1 are assignable to ns (CrOO) coupled with ring deformation, Cr-Cr mode coupled with ds (Cr-Cr-O) bending and nas (CrOO) coupled with das (C-O-Cr) bending, respectively.
Keywords: Infrared spectrum, normal coordinate treatment, in-plane fundamental vibrations, tetra- m- formato dichromium (II) complex, 1:1 (Cr24+: HCOO-) complex model.

Bayesian model averaging attempts to combine parameter estimation and model uncertainty in one coherent framework. The choice of prior is then critical. Within an explicit framework of ignorance we define a 'suitable' prior as one which leads to a continuous and suitable analog to the pretest estimator. The normal prior, used in standard Bayesian model averaging, is shown to be unsuitable. The Laplace (or lasso) prior is almost suitable. A suitable prior (the Subbotin prior) is proposed and its properties are investigated.


During the fermentation of corn stalk bio-feed, the quantity of bacteria in corn stalk bio-feed was counted by fluorescence quantitative PCR and plate colony counting respectively. The comparative analysis of these studies was used to explore the feasibility of fluorescence quantification methods and changes in microbiota during fermentation. The results showed that the standard deviation of fluorescence quantitative method was smaller than that of plate method, but the trend was similar. The biomass of Bacillus subtilis, Lactobacillus plantarum and Saccharomyces cerevisiae reached their maximum on the third, fifth and fifth day respectively, and then decreased gradually and maintained at a certain level. The experiment showed that the fluorescence quantitative PCR method can accurately quantify the number of bacteria in corn stalk bio-feed, and it is a better method to quantitatively detect the dynamic changes of different kinds of bacteria in corn stalk bio-feed.


The study aimed to identify the direct effects of both psychological empowerment and work flow on professional commitment, and this study was applied to all employees of the Jordanian Ministry of Education. The descriptive analytical approach was used, and the study sample consisted of (463) employees in the ministry, and the researchers prepared three measures for each of psychological empowerment, work flow and professional commitment. The results of the study concluded that there is a direct and positive semantic effect of psychological empowerment and work flow in professional commitment, in addition to the presence of a direct and positive semantic effect of work flow in professional commitment. The study recommended conducting a similar study for other ministries in order to generalize the results.


Printed read-only memory (ROM) would be a key component for many envisioned printed electronics applications such as item identification, anti-counterfeiting, brand protection and supply chain management. This paper will firstly introduce the electrical requirements on the memories to be operated in power constrained mobile readout systems for these targeted applications. Then, two types of printed ROMs, including polymer resistive type ROM and fuse-type electrically programmable write-once-read-many (WORM) ROM, will be presented. For the former, the instability issues associated with the conventional PEDOT: PSS and its interface with contact electrodes will be revealed. This work proves that, by removing the hydrophilic acidic groups in conventional PEDOT: PSS, these instability issues can be well addressed. The ROM tags fabricated based on the modified PEDOT: PSS of neutral pH and inkjet printed silver electrodes present extremely stable performance under both aging and electrical stress tests in air ambient. For the latter, fuse-type WORM ROMs are fabricated using a common material inkjet printer to form both the contact pads and the resistor tracks with the same silver ink and process settings. Based on the dependence of the fusing voltage on the length of the printed resistor track, a new cell structure is proposed to achieve multi-bit memories with greatly saved contact pad numbers for easier external electrical connections than the conventional design. The memory cells also present excellent long-term storage and operation stabilities. The function of the printed ROMs are finally demonstrated with mobile readout hardware systems.

Background & Objective: Female athletes are at an increasing risk of depleting their iron stores and iron deficiency. It has recently been suggested that hepcidin may be an important regulator of whole-body iron homeostasis. Then, the purpose of the present study was to investigate the effects of exhaustive exercises on hepcidin hormone, iron, ferritin, and hemoglobin of female athletes. Materials & Methods: 30 female athletes were selected for the study and were randomly assigned to experimental and control groups. The participants' fasting blood samples were taken 2 h before exercise (including 3*6 repetition), just 3 and 24 hours after exhaustive exercise. Data analysis was carried out using repeated measure and ANOVA. Results: The results showed that hepcidin increased significantly after the exercise in the experimental group (P= 0.001) and the highest increase was 3 hours after exercise (P= 0.004). Also Iron (P= 0.001), ferritin (P= 0.001) and hemoglobin (P= 0.001) increased significantly just after exercise. However, the hemoglobin value during 3 hours post exercise decreased compared to pre-exercise (P= 0.01). Conclusion: It is concluded that a session of acute exercise can increase the hepcidin and hence help absorb and maintain iron.

From the pioneering work that the Buchanan group started in the late 1960s, we know that the division of photosynthesis into light and dark reactions is inadequate because the activity of a number of chloroplast enzymes, many involved in the Calvin–Benson cycle, is strictly controlled by light; that is, they are activated in the light and deactivated in the dark. An exception is glucose-6-phosphate dehydrogenase, which is regulated in an opposite manner; that is, activation in the dark and deactivation in the light. It took a decade to biochemically dissect the newly identifed redox regulatory pathway responsible for this regulation. Known as the ferredoxin-thioredoxin system, the pathway is composed of three components: ferredoxin, ferredoxin-thioredoxin reductase (FTR), and thioredoxin (Trx) that relay the reducing power generated at photosystem 1 (PSI) to target regulatory enzymes (1, 2).

Over the last four decades there have been a number of milestones in the field of redox regulation in plants. The first step was to identify ferredoxin, FTR, and Trx as key components of the regulatory system. We then observed that there were multiple Trxs with differential selectivities in plant eukaryotic cells, and although this seems of little significance now, in the genomic era it was the subject of intense debate at the time. A very important contribution was the elucidation of the 3D structures and catalytic mechanisms of FTRs and Trxs. A lot of effort has also been …

By the MP2 method,the fully optimized geometries of transition states in the process of the CH2O and CHO reactions to N,to NH and to NH2 respectively were calculated at the level of 6-311G** and 6-311++G**,and then such geometries were confirmed through vibration analysis.Changes of bond lengths of interacting molecules were analyzed along the minimum energy paths(MEP) with the IRC theory.Finally,the reaction potential barriers were figured out by computing the single point energy at the same level in the way of QCISD.It was found that the whole process of the C—H bond breaking and the N—H bond forming went in the way of concerted reactions,ranging from the reactants like CH2O and N to the final products like CO and NH3.The chain reaction(reaction(1)and(5)) was the most favorable path in all six reactions,and through topological analysis of the major critical points along the reaction pathway in the CH2O reactions to N,to NH and to NH2,we found all reactions around the transition states(S=0) that the chemical bonds forming or breaking happened after such states in the case of the three CHO reactions.
