The complex permittivity at 5.8 GHz of the composites of epoxy resin with multi-walled carbon nanotubes (MWCNTs) with their 20-70 nm diameters and 10-20 mum lengths at the concentration of 0.1-0.5% in weight was measured using a waveguide in order to develop the electromagnetic wave absorber (EMA) in the GHz frequency region. The EM absorbing efficiency was the highest at the MWCNT concentration of 0.2%, although the electric resistivity of the composite decreased and the electromagnetic interference shielding efficiency at 1-18 GHz increased with concentration of MWCNT over 0.5%. Such was observed even in various polymers including polycarbonate, polyacetal, polystyrene, acrylonitrile-butadiene-styrene copolymer, polymethylmethacrylate, and poly-etheretherketone


We Believe In the Systems That Keep Us Alive is a body of work that uses parallels identified between writing and media critique of contemporary events. The parallels are labeled as four specific systems: nutritional, administrative, life-support, and nurturing. Through a combination of interactive and object based sculpture, each system is represented with visual metaphor and allegory to place the viewer in a direct and specialized paradox. Paradoxes audience members encounter are intended to illustrate to the audience what conflicts can arise by being included in a system where governing agency of any sort does not meet with individual desires.


Leptospirosis is an infectious disease that affects practically all domestic and wild animals, which can become carriers and, as a consequence, will contribute to the spread of the microorganism in nature. The present study aims to detect the occurrence of leptospirosis against by the microscopic serum agglutination test in animals at the Zoo of the Centro Universitário da Amazônia (ZOOUNAMA). 26 adult animals of both sexes and of the following species: 9 Sapajus apella, 2 Cebus kaapori, 3 Ateles marginatus, 10 Ateles paniscus, 1 Chiropetes satanas, 1 Allouata belzebul. Of the animals studied, 3 (11.5%) were reagents to be taken against Leptospira spp. The serovars found in the different species were: Icterohaemorragiae, Balum, Hardjo and Grippothyphosa. SAM proved to be efficient to detect against leptospira in non-human primates. Icterohaemorragiae type serum occurred with research results showing that it is also important in leptospirosis in non-human primates.


ABSTRACT... Objectives: To compare the efficacy of 0.2% glyceryl trinitrate ointment versus internal sphincterotomy after hemorrhoidectomy. Study Design: Randomized Controlled Trial. Setting: Department of Surgery Unit III, at Lahore General Hospital, Lahore. Period: 6 months (August 2017 to February 2018). Material & Methods: The OPD of the Department of Surgery included 124 patients who satisfied the inclusion criteria. There were two groups of patients, Group A and Group B. Group-A was told to use gloved finger three times daily for 0.2 percent GTN ointment topically. For Group B, lateral internal sphincterotomy was performed as day care procedure. On visit, patients were assessed for pain relief by using VAS. All data was collected using a pre-designed (attached) proforma. In SPSS v23.0 the data were input and analyzed. It was stratified for age, sex, disease duration and hemorrhoid stage. The effectiveness of both groups was compared by using a p-value of 0.05 as significant for a chi-square test. Results: Male predominance; in group-A, 41(66.1%) patients were male and 21(33.9%) were female, while in group-B, 52(83.9%) patients were male and 10(16.1%) were females. Efficacy was found in 11(17.7%) patients in group-A (0.2% GTN) while in 25(40.3%) patients in group-B (Internal sphincterotomy) with p-value of 0.006 which is statistically significant. Conclusion: Open hemorrhoidectomy internal sphincterotomy is an effective method to reduce pain after hemorrhoidectomy in contrast to Glyceryl Trinitrate (GTN) topical cream of 0.2 percent.


Abstract In this paper, effects of the defect in an adhesively bonded joint have been investigated using cohesive zone modeling. Consequently, a 3D finite element model of a single lap-joint is constructed and validated with experiments. Strength prediction of current model is found desirable. Accordingly, different sizes of square shape defects are imported to model in the form of changing (raised or degraded) material properties (heterogeneity) and locally delaminated areas (as inclusion/void), respectively. Joint strength is investigated and a stress analysis is carried out for adhesive layer and adherends. Obtained Results show that, defect has significant impact on the results. It is found that at constant size of defect, local delamination has more impact on bonded joint strength than the heterogeneity. Furthermore, stress analyses demonstrate that the stress field does not change in adherends by taking defects into account. However, stress values decrease with degraded material properties and joint's strength. Through evaluation of peel and transverse shear stresses in adhesive layer it is found that there is a change of stress distribution for both types of defects. Whereas, there is a considerable stress concentration in the delaminated adhesive layer.

Abstract Starting from the relations between entries of block pulse operational matrices, block pulse regression equations corresponding to the original differential equation models with time-varying parameters are obtained. Based on simple forms of the regression equations, algorithms developed in discrete-time model identification can be applied directly to estimate the time-varying parameters of the continuous models without much modification. Compared with other identification methods for the same problem, this new method is simple, and can be applied to both batch and recursive estimations of continuous time-varying linear systems from their sampled input and output data by means of digital computers.


The microscopic flame structure of a composite propellant is expected to change significantly as the particle size distribution is varied. However, until recently it has not been possible to observe the flame structure in a burning composite propellant. In this paper we report observations of the diffusion flame structures above ammonium perchlorate (AP) composite propellants with varying ratios of coarse AP and fine AP. The coarse-to-fine (C/F) ratio was varied between 1:16 (mostly fine AP) to 16:1 (mostly coarse AP). Flame structures were imaged at atmospheric and elevated pressures using 5 kHz OH planar laser induced fluorescence (PLIF) that allows imaging of these highly transient microscale (100s of microns) flames. Single AP particle ignition delay, burning rate, and lifetime were measured at one atmosphere. While the coarse AP particle lifetime is similar across C/F ratios, the coarse particle ignition delay and the percent of coarse crystal lifetime spent in ignition delay differ between the 1:16 C/F ratio and higher C/F ratio propellants, indicating that nearby particles affect ignition. Jet-like diffusion flames are seen for all C/F ratio propellants at one atmosphere. At elevated pressures, lifted inverted overventilated diffusion flames (IOFs) are seen for all C/F ratio propellants except the lowest, for which jet-like flames are observed. Differences in the flame structures at elevated pressures are postulated to be due to the dissimilar local burning rates of the fine AP/binder matrix (or "dirty binder") as C/F ratios change. Interacting diffusion flames of adjacent coarse AP particles were observed and indicate group combustion. This was observed at all pressures and C/F ratios, except for the 1:16 C/F ratio propellant. Group combustion is more often observed for higher C/F ratios. We present examples of group combustion of particles that are typically not considered in simple models. It is found that at one atmosphere the largest effect of group combustion is on ignition delay. There are also effects on flame height due to group combustion of crystals. At elevated pressures, group combustion is also suspected to distort the bowl-like shape of the lifted IOF.


Background and purpose: The midwife's self-efficacy in supporting mothers during labor affects the onset of midwifery support in labor and childbirth. To date, there is no appropriate national instrument for measuring midwives self-efficacy of labor support in Iran. The present study aimed to investigate the factorial structure, validity and reliability of the Persian version of the self-efficacy for labor support scale. Materials and methods: A methodological study was carried out in which 213 midwives from selected hospitals affiliated to Tehran University of Medical Sciences enrolled between January 2017 and September 2017. The participants completed a demographic questionnaire and the self-efficacy for labor support scale. In order to assess the validity of the instrument, qualitative face and content validity was performed. Construct validity was also evaluated using confirmatory factor analysis. Finally, the reliability of the scale was studied by Spearman's correlation coefficient and internal consistency. Results: The qualitative face and content validity of the Persian version of labor support selfefficacy scale was confirmed, and a confirmatory factor analysis showed that it was well structured. The reliability of the scale using Cronbach's alpha coefficient was 0.93 and the Spearman's coefficient correlation was 0.72 indicating a good reliability of the Persian version of the scale. Conclusion: The findings showed that the Persian version of the self-efficacy for labor support scale has good validity and reliability and could be used as an appropriate instrument for assessing selfefficacy for labor support by midwives in Iran.


Aim: To evaluate the tendency, knowledge, awareness and behavior
patterns of urology residents training at different institutions in
Turkey about the use of fluoroscopy in operations. Methods: The
13-questioned survey prepared using "Google Forms©" as of 01.03.2021
was shared for four weeks in the "WhatsApp®" application group, which
includes 279 urology residents studying with university hospitals and
training and research hospitals in Turkey. One hundred and thirteen
participants, who completed the questionnaire were included in the
study. Results: Of the 113 urology residents included in the study, 56
(49.6%) were studying in university hospitals and 57 (50.4%) were in
training and research hospitals. 67.3% of the residents stated that
they never hesitated to participate in the operations which fluoroscopy
was used. Additionally, the residents stated that, also 43.4% of the
auxiliary healthcare staff frequently refrain from being involved in
these cases(p <0.001). While 21 (37.5%) of the residents
trained in the university hospital reported that they hesitated from
these cases, this rate was found that 16 (28.2%) of the residents who
were trained in the training and research hospitals and a significant
difference was observed between two groups (p <0.016). Among
residents, the rate of using radioprotective lead apron was 94.7%, and
the rate of thyroid shield use was 98.2%. While the rate of using
radiation protective glasses was 1.8%, it was learned that none of the
residents used radioprotective gloves. Only 5.3% of the residents
stated that they are trained in subjects about the harmful radiation
effect. Conclusion: Urology residents in Turkey do not receive
sufficient training on the harmful effects of fluoroscopy, which they
frequently use in their daily practice. In addition, the residents whom
training in university hospitals are more scared of the radiation
exposure from fluoroscopy than their colleagues working in training and
research hospitals.


3D parcels and their assembly are the primary objects in 3D land administration system.Unfortunately,many methods are developed to validate the single existed solid afterwards,rather than to build the valid 3D solid straightforwardly from the input facets.An effective direct approach is developed to construct the valid solid based on discrete geometric facets,which is vital for 3D cadastral modeling,especially for the collections of 3D property units.The 3D topological mode and the relationships among basic primitives(vertex,edge,facet and solid) are proposed.Based on the prerequisite constraints about initial geometrics and topologies of the input facets,the process of automatic construction of valid solids and their collections is detailed.The approach,automatic construction of valid solids and their aggregation based on discrete facets,satisfies the validation and supports various singularities of 3D solids.


This study aims to develop student worksheets based on mathematical communication skills. It used the ADDIE model (Analysis, Design, Development, Implementation, Evaluation) to develop and evaluate the worksheet. The subjects of this study were students of class VII in one of the junior high schools in Yogyakarta. The testing consisted of two stages, namely the small-scale trial consisting of 5 students and a large-scale trial consisting of 31 students. We collected the data using questionnaire for material and media experts' judgment as well as for the students' responses. Then, we analyzed the validity and practicality of the worksheet. Finally, the results of the assessment of material experts and media experts obtained an overall average score of 4.29 (very good category), so that the mathematical communication skills worksheet considered valid. Meanwhile, the students' responses to the worksheets were practical with an average score of 3.1 (good category).


10 Recent studies suggest that as many as 25% of all students who enter first grade will not graduate from a traditional high school (O'Sullivan, 1988; Phlegar & Rose, 1988). Previous efforts to both identify and/or rehabilitate students at risk has traditionally focused on the high school level. Educators are now realizing that the best way to prevent high school students from dropping out is to address their problems in the elementary or middle school. This article will focus on the middle school where students


Objective Studies on maladaptive daydreaming have shown that it has a number of comorbidities including dissociative disorders, yet no studies have examined the reciprocal relationship. The aim of this study was to determine the frequency of maladaptive daydreaming in a sample of psychiatric inpatients with high levels of dissociation. Methods The Dissociative Experiences Scale (DES), Self‐Report Dissociative Disorders Interview Schedule, Maladaptive Daydreaming Scale‐16 (MDS‐16), Structured Clinical Interview for Maladaptive Daydreaming, and the Obsessive Compulsive Inventory were administered to a sample of 100 inpatients in a psychiatric hospital program specializing in dissociative disorders. Results Of the 100 participants, 93 reported childhood physical and/or sexual abuse, 33 met criteria for dissociative identity disorder; 56 met criteria for other specified dissociative disorder, 49 met criteria for maladaptive daydreaming disorder, and 23 met criteria for unspecified maladaptive daydreaming. The average score on the DES was 39.1 and the average score on the MDS‐16 was 33.9. Individuals with maladaptive daydreaming disorder scored significantly higher than those without on many different symptom clusters. Conclusions This sample of 100 highly traumatized and dissociative inpatients reported high levels of maladaptive daydreaming along with many other forms of comorbidity. Maladaptive daydreaming is a previously under‐recognized aspect of complex dissociative disorders and requires further attention in both research and clinical practice.

The Hanford Waste Vitrification Plant will be constructed to treat the high-level fraction of the radioactive liquid waste stored in tanks at the Hanford Site. Normal permitting practices under the Washington State Dangerous Waste Regulations require a facility to apply for and receive a final facility permit based on a completed design prior to the start of facility construction. However, the enormity and complexity of a project the size of the Hanford Waste Vitrification Plant dictates that construction begin before design is complete. An innovative permitting strategy has been developed to initiate timely construction of the Hanford Waste Vitrification Plant while providing the Washington State Department of Ecology with the necessary regulatory oversight. This strategy calls for a multi-stage'' permitting process, a process in which permits will be issued at various stages of facility design, construction, and operation. This process will also include Washington State Department of Ecology staff participation in the review of draft drawings and specifications, monthly meetings with the US Department of Energy, and onsite inspections. The concept of permitting the Hanford Waste Vitrification Plant at various stages in the design and construction process is a novel approach to the normal regulatory procedure of a single finalmore » permit. This approach will allow the Hanford Waste Vitrification Plant Project to stay on schedule while still maintaining the regulatory agency's oversight role. 6 refs., 5 figs.« less

The NASA Space Radiation Laboratory (NSRL) at BNL was commissioned in October 2002 and the facility became operational in July 2003. NSRL was constructed in collaboration with NASA for the purpose of performing radiation effect studies for the NASA space program. NSRL can accept a wide variety of ions from BNL's AGS Booster; these are slow extracted with kinetic energies ranging from 0.3 to 3 GeV/n. Fast extraction from Booster to NSRL has also been developed and used. Many different beam conditions have been produced for experiments at NSRL, including very low intensity. In this report we will describe the facility and its performance over the eight experimental run periods that have taken place since it became operational. We will also describe the current and future capabilities of the NSRL.


The opioid epidemic has become a national crisis. The number of overdose deaths involving opioids has quadrupled since 1999.[1][1] Indeed, the United States, with 5% of the global population, consumes 80% of the global opioid supply.[2][2] This epidemic has rightly entered the national consciousness


It has been 20 years since the fall of the Berlin Wall. We are 'celebrating' this anniversary at a time when global capitalism and liberal democracy, the so-called winners of the Cold War struggle between East and West, find themselves
in one of the deepest economic and political crises since the Wall Street crash in 1929 and the global turmoil that followed. Perhaps more significantly, however, this is the first crisis that Eastern Europeans are experiencing since
their so-called 'transition' from a state socialist to a capitalist ideology. What should we make of this transition since 1989? Rather than engaging in a traditional analysis of the winners and losers of this transition, I am interested in what today's capitalist crisis has perhaps in
common with the crisis of state socialism in 1989. I will explore this question by engaging with the German film

In the modern conditions of the development of digitalization, an increase in the volume of the information used and the speed of decision-making, there comes an understanding that the effective control of various business processes can be ensured as promptly and efficiently as possible only through intra-production administration. Management control is designed to provide this function. At the same time, the implementation of control measures in relation to the accomplished facts of economic life is not enough to make effective management decisions. Therefore, it is necessary to carry out both the retrospective and prospective control. This problem determined the aim of this study, which is the development of such methodology for organizing management control, which will ensure the tax security of an economic entity through the application of preliminary and subsequent control procedures. This goal is achieved by clarifying the control environment elements available in the scientific literature and developing a list of relevant procedures for the management control of tax liabilities. The result of this study is the developed methodology for organizing management control, through which an acceptable level of tax security of enterprises is ensured. Within the framework of the study, the author paid special attention to the managerial control procedures, which allow realizing its prospective nature – tax analysis and tax passport completion. Within tax analysis, the author proposes separating the strategic and subsequent analysis. To assess the state of the tax system of an economic entity, a number of coefficients corresponding to the areas of tax analysis were developed and proposed for use in practice. Besides, the author proposed to form a tax passport of an enterprise and determined its structure. The organization of managerial control according to the proposed methodology contributes to the consistency of intra-production tax administration with the requirements of state tax control and ensures the stable tax security of an economic entity and the necessary information component for making management decisions related to tax liabilities.


This study examines the impact of conditional and unconditional conservatism on earnings quality of listed companies in Tehran Stock Exchange during 1385 to 1390. This study uses temporal asymmetry Basoo models with adding of certain variables to measure conservatism. In this study, panel data analysis is used for stock exchange listed companies. This research was presented in the form of two hypotheses, and the statistical results have shown that DR*RET variable is significantly valid at the 0.05. This shows that the samples in this study are conservative in reporting their financial statements. Coefficient of earnings quality (CFO/NI) is not significant, which indicates that there is no significant relationship between earnings quality and conditional conservatism reflected in corporate profits. Earning quality variable coefficient equals to 0.0004 and adding MTB variable is not significant, this finding indicates that there is no significant relationship between earnings quality and unconditional conservatism on firms. Therefore, the first and the second hypothesis of this study cannot be approved.

Previous studies have shown declining rates of pulpal anesthesia over 60 minutes when a cartridge of 4% articaine is used with 1:100,000 epinephrine for buccal infiltration in the mandibular first molar. The authors conducted a prospective, randomized, single-blind, crossover study comparing the degree of pulpal anesthesia obtained with 2 sets of mandibular first molar buccal infiltrations, given in 2 separate appointments, to 86 adult subjects: an initial infiltration of a cartridge of 4% articaine with 1:100,000 epinephrine plus a repeated infiltration of the same anesthetic and dose given 25 minutes following the initial infiltration versus an initial infiltration of a cartridge of 4% articaine with 1:100,000 epinephrine plus a mock repeated infiltration given 25 minutes following the initial infiltration. The authors used an electric pulp tester to test the first molar for anesthesia in 3-minute cycles for 112 minutes after the injections. The repeated infiltration significantly improved pulpal anesthesia from 28 minutes through 109 minutes in the mandibular first molar. A repeated infiltration of a cartridge of 4% articaine with 1:100,000 epinephrine given 25 minutes after an initial infiltration of the same type and dose of anesthetic significantly improved the duration of pulpal anesthesia, when compared with only an initial buccal infiltration, in the mandibular first molar.


Variable time-step numerical schemes applied to an autonomous differential equation generate cocycles rather than semigroups, so their asymptotic behaviour must be described in terms of cocycle attractors consisting of an equivariant family of sets in contrast to the single invariant set forming the attractor of a constant time-step scheme. The existence of such cocycle attractors is established here for a special linear-implicit versio of the Euler scheme with variable time-steps that is applied to a class of autonomous linear-quadratic differential equations of similar structure to the Lorenz equations. The relationship between the numerical cocycle attractors and the original global attractor of the differential equation is also investigated.


The morphology of the first damage occurring on either single layer materials or multilayer HR coatings are studied using Scanning Electron Microscopy. For single layers obtained by electron beam evaporation or ion beam sputtering, the damages are always centered on a small size center of about 0.1 micrometers . This center triggers the degradation which presents a well defined shape and size. Two kinds of damage mechanisms occur, either melting of the layer or mechanical breaking of the layer. The same behavior is observed on HR coatings with damage centers located at the interfaces between the high and low index materials of the stack. From these experiments an impurity dominated model is proposed which enables the main features of UV damages to be understood.

There has been a tremendous amount of research in the area of image halftoning. Where the goal has been to find the most visually accurate representation given a limited palette of gray- levels (often just two, black and white). This paper focuses on the inverse problem, that of finding efficient techniques for reconstructing high-quality continuous-tone images from their halftoned versions. The proposed algorithms are based on a maximum a posteriori (MAP) estimation criteria using a Markov random field model for the prior image distribution. Image estimates obtained with the proposed model accurately reconstruct both the smooth regions of the image and the discontinuities along the edges. Algorithms are developed and example gray-level reconstructions are presented generated from both dithered and error diffused halftone originals.


Ginger is a tuber that is consumed whole as delicacy, medicine, or a spice. Ginger cultivation began in Asia and has since spread to West Africa and the Caribbean. Ginger is cultivated in many parts of India; on a large scale in the warm, moist regions, chiefly in Madras, Cochin and Travancore, and to a somewhat less extent in Bengal and Punjab. Medicinal properties of the ginger mentioned in classical Unani text have been explored in this paper and chemical constituents of the drug have also been cited.


Objectives: To report the anatomic parameters and the anti-stretch property of transverse ligament of atlas. Methods: 24 adult C 1~C 2 fixated specimens and 9 fresh transverse ligament specimens were used. To observe the anatomic characters of the transverse ligament of atlas, the length, thickness and the width in center and the widths in both sides were measured. Two of the nine fresh transverse ligament specimens were observed in histology, and seven of them were used to test the anti-stretch property on a material testing machine (MTS 858 Bionix test system, USA). Results: The length of the transverse ligament of atlas was 20.0±2.4 mm, the thickness of the center was 2.1±0.5 mm, the width of the center was 10.7±1.6 mm, the widths of left and right end were 6.6±1.1 mm and 6.7±1.0 mm respectively, and the thickness of the two end were 3.8±1.1 mm and 3.7±1.1 mm respectively. The relationship between the transverse ligament of atlas and the odontoid process of axis was classified by three types: 1. The odontoid process was completely coated by the transverse ligament from behind, 10 of 33 (30.3%) were observed in our study. 2. The odontoid process was partly, but more than 1/2, coated by the transverse ligament, 18 of 33 (54.5%) were observed in our study. 3. The odontoid process was partly, but less than 1/2, coated by the transverse ligament, 5 of 33 (15.2%) were observed in our study. In the central part of the surface of the transverse ligament, which was facing the odontoid process, some longitudinal fibers had been found and confirmed to be loose connective tissue in histology. The average of the max load of the transverse ligament was 605.5±89.6N, and the average of the max deformation of the transverse ligament was 4.3±0.5mm. Conclusions: Contrast to the foreigner's, the transverse ligament of atlas of Chinese people is shorter than that of White race, and it almost the same as that of Yellow race. In the surface of the transverse ligament of atlas, which is facing the odontoid process, there may have some loose connective tissue. The relationship between the transverse ligament and the odontoid process is not invariable which may be the anatomic base of the dens fracture.


Event-based software architectures are commonly used to solve a variety of problems. These architectures are complex to design and implement, however, especially with conventional, textual programming languages. We describe our recent work in developing visual languages and support environments for the design and implementation of a range of event-based software architectures. A synthesis of this work to produce a more general architecture description language and support environment is described.


In this paper we consider the problem of organizing networks of spatially embedded oscillators to maximize the propensity for synchronization for limited availability of wire, needed to realize the physical connections between the oscillators. We consider two extensions of previous work (Brede, 2010b): (i) oscillators that can flexibly arrange in space during the optimization process and (ii) a generalization to weighted networks. In the first case, we discuss the emergence of spatially and relationally modular network organizations, while in the second case the emphasis of our analysis is on link heterogeneity and the particular organization of strong and weak links that facilitates synchronization in space.


Walnut propagation is one of the limitations to expanding the crop of this species. The production of grafted material is expensive and needs time. This situation seems to be changing, nowadays it is possible to get self-rooted material, in vitro, of the most important cultivars. However, information on the performance of these materials in orchards is not well known. In order to evaluate walnut production according the origin of the material (self-rooted or grafted), in February 1999, two trials were planted, one with 'Chander' cv. and the other with 'Vina' cv. in Gimenells, Lleida (North-West Spain). Both cultivars showed a different behaviour in growth between self rooted and grafted. 'Vina' cv. did not show any differences during the juvenile period, however, after the 8 th leaf self-rooted material showed higher values. 'Chandler' cv. presented differences during the juvenile period, grafted material having better growth, although the difference disappeared at the 8 th leaf. Important differences were observed in the phenology. The leafing out date of in vitro material was late in both cultivars; ranging from three to nine days. This gap was present also in flowering and harvest time. The different rootstock caused the male flower presence to appear some years earlier than for self-rooted material. In the first 3 harvest years, tree production of grafted plants exceeded the production of in vitro plants in both cultivars. From the 4 th production year (8 th leaf) the harvest of both material types was similar in `Chandler' and 'Vina' cvs.

The paper Efficient Query Processing for Dynamically Changing Datasets, by Muhammad Idris, Mart´n Ugarte, Stijn Vansummeren, Hannes Voigt, and Wolfgang Lehner studies two central aspects of answering queries: (1) enumerating the answers to a query and (2) changing data. It is based on two papers by the same authors or a subset thereof, namely The Dynamic Yannakakis Algorithm: Compact and Efficient Query Processing Under Updates [4] and Conjunctive Queries with Inequalities Under Updates [5].


In this paper we wish to highlight the role played by the town of Tarifa during the cantonal insurrectionthat took place in Spain in the summer of 1873. During the short period of Glorious Revolution Spain underwent a series of transformations that involved the country in a democratic adventure ending with the Bourbon Restoration through the sudden proclamation of Alfonso XII as king. During those years, and after the abdication of Amadeo of Savoy, the first Spanish Republic was established. This lasted less than a year due to, among other reasons, a revolt originating in Cartagena that spread to numerous towns and brought the recently founded republic to an end. The canton established in Cartagena is undoubtedly well-known, this being the earliest one and also the last one to be reduced. However, besides Cartagena and other Spanish areas, cantonalism had a great impact in the province of Cadiz, especially in the town of Tarifa which thus played one of its latest significant roles in the history Spain.


Jasmonic acid (JA) is a lipid-derived plant hormone that mediates diverse biological phenomena. It is one of major goals in JA research field to elucidate the regulatory mechanism of JA level. Recently, we have demonstrated cooperative and differentiated roles of two chloroplast localized galactolipases, DGL (DONGLE) and DAD1 (DEFECTIVE IN ANTHER DEHISCENCE 1), for the regulation of JA content. The DGL maintains a basal level of JA in unwounded vegetative tissues, while the DAD1 is involved in JA production in floral tissues. The JA in vegetative tissues regulates cell expansion while the JA produced in flowers regulates pollen maturation. After wounding, the cooperative function of DGL and DAD1 causes drastic increase of JA. The analysis of induction kinetics showed that the two enzymes have temporally separated roles in wound response; DGL in early phase and DAD1 in late phase of JA production. In this addendum, we discuss the implications of our recent findings and extend our working model for JA homeostasis in plants.

BACKGROUND: Polypropylene (PP) is one of the most widely used polyolefins but gets restricted in surface applications due to its non-polar nature. Surface properties of films made of PP were modified to improve their adhesion to elastomeric polymers such as thermoplastic polyurethanes (TPU), especially to Pebax® [poly(ether-block-amide)].

RESULTS: Surface modification of PP was brought about by blending it with glycidyl methacrylate (GMA)-containing polymer to increase its surface energy. Films of modified PP were analyzed to determine the blending efficiency and characterized using contact angle measurements, differential scanning calorimetry, X-ray photoelectron spectroscopy and scanning electron microscopy. Molecular dynamics simulations were done to determine surface and bulk properties of PP blended with GMA. The computational results correlated very well with the experimental data and revealed that the changes in the surface energy can be linked to the position of the functional group within the sample. T-Peel tests indicated a 2.4 times increase in adhesion to Pebax® and only 1.7 times increase in adhesion to TPU compared to unmodified PP.

CONCLUSION: The surface energy and enhanced adhesion proved that PP was successfully modified and its surface made more polar. Copyright © 2008 Society of Chemical Industry


Abstract The purpose of this paper is to investigate whether audit firm reputation provides insight into financial reporting quality of listed companies in Vietnam. Earning management measured by accrual earning management and real earning management is compared between firms audited by Big 4 auditors and non-Big 4. Using difference in differences approach on the sample of 331 listed companies in Vietnam during 2013–2020, the study finds that Big 4 improves financial report quality through decreasing earning management. The role of Big 4 auditor in monitoring real earing management is more significant than accrual earning management in auditing year because real earning management has been preferred over accrual in years before. This study could provide valuable information for investors and shareholders when using financial report as well as the Government administration in preventing earning management practices and promoting high level of accounting and auditing compliance.

Gallium nitride (GaN) is one of the most significant elements to achieve effective use of energy in space not only for communications but also for power transmissions. This is because that GaN has the features such as high efficiency, high breakdown voltage, and harsh environment robustness and it is expected to fit the requirements for space use. Using GaN, the flexibilities for future missions in terms of size, weight, and power consumption etc. will be improved significantly. In this research, as a high power and high efficiency device, use of a GaN device was tried in a high power FET amplifier and in a single shunt rectifier diode. Circuits operating at S-band were designed, produced, and evaluated experimentally with the DC-RF conversion of 63.3% in the power amplifier and with the RF-DC one of 35.5% in the rectifier diode. A wireless power transmission (WPT) experiment using HPA and rectenna was conducted. As a result, it was confirmed that a battery could be charged up to 133.7 Ws in about 1500 s (25 min) by the DC power generated by the rectifier, where the EIRP was 57.2 dBm, the rectifier input power was 32.5 dBm, and the distance between a power transmitter and the receiver was 1.2 m.

Biochar is environmental friendly materials that can be used for environmental protection. In the research, the application of biochar for phosphate adsorption and recovery from wastewater was examined. The material surface characterization analysis, include Transmission Electron Microscope with energy dispersive X-ray spectroscopy and Fourier Transform Infrared spectroscopy, was performed to characterize the prepared biochar. The application analysis, include optimal solution pH and interfering ions effect, was performed for phosphate adsorption and recovery from wastewater. The research conclusions were drawn as follow: (1) material surface characterization demonstrated the prepared biochar was coarse, unshaped, irregular, and contained a great deal of carbon; (2) application analysis indicated biochar adsorption amount for phosphate was decrease with an increase in solution pH, and biochar adsorption amount for phosphate was also decrease with an increase in interfering ions concentration.


OBJECTIVES: Nonalcoholic steatohepatitis (NASH) and fibrosis play critical roles for the prognosis of patients with nonalcoholic fatty liver disease (NAFLD). Identification of patients at risk of NASH and fibrosis is therefore critical for disease management. NAFLD Fibrosis Score (NFS) and transient elastography (TE) have been suggested to exclude advanced fibrosis. However, there is increasing evidence that also patients with NASH and early fibrosis are at risk of disease progression and complications, emphasizing the need for improved noninvasive risk stratification in NAFLD. METHODS: Because hepatocyte apoptosis plays an early role in NASH pathogenesis, we evaluated whether the apoptosis biomarker M30 might identify NAFLD patients who are at risk of NASH and fibrosis despite low NFS or TE values. Serum M30 levels were assessed by enzyme-linked immunosorbent assay in combination with NFS and/or TE in an exploration (n = 103) and validation (n = 100) cohort of patients with biopsy-proven NAFLD. RESULTS: Most patients with low NFS (cutoff value < −1.455) revealed increased M30 levels (>200 U/L) in the exploration (62%) and validation (67%) cohort, and more than 70% of them had NASH, mostly with histological fibrosis. Vice versa, most patients with NFS < −1.455 but nonelevated M30 levels showed no NASH. NASH was also detected in most patients with indeterminate NFS (−1.455 to 0.676) but elevated M30 levels, from which ∼90% showed fibrosis. Similar results were obtained when using TE instead of NFS. DISCUSSION: The combination of the M30 biomarker with NFS or TE enables a more reliable identification of patients with an increased risk of progressed NAFLD and improves patient stratification.


This paper presents air suspended broadband gap coupled E-shaped microstrip antenna. Single E-shaped microstrip antenna realizes impedance bandwidth of 152 MHz. Further bandwidth enhancement is achieved using gap coupling with parasitically coupled rectangular patch without slots. This configuration achieves bandwidth of about 171 MHz. Further, slots are cut inside the parasitically coupled rectangular patch and bandwidth of 201 MHz has been realized. The proposed antenna structure is designed and fabricated using FR4 substrate and suspended in air to improve the radiation characteristics. The antenna radiates in broadside direction. The antenna offers peak gain more than 9 dBi at lower frequency band which is the novelty in the proposed design. The fabricated antenna is tested and the measured results are presented. The detailed parametric analysis of proposed antenna has been carried out to optimize the dimensions of antenna. The equivalent circuit of antenna have been prepared and presented in this paper.

We illustrate three dimensions which come under the notion of work and draw up a genealogy of each one. The anthropological dimension of work deals with the technical act upon nature, creator of social worlds. The economic dimension of work is concerned with the production of goods. The social dimension of work deals with the legal status of workers and the rights which come from employment. First at all we study the philosophy of work by looking at works by Marx and Simone Weil, and we consider in what ways the French working-class movement is suited to this. Secondly, we consider the French economic evolution from 1945 to the present day. We demonstrate the ways in which the society of production has transformed and diversified the different paid activities that exist. Finally, we question the emergence of the notion of social links. This notion denotes partly, the interdependence of workers (employees, management, independent workers) thanks to Social Security, and also, the sociability (meetings, dialogues, communication). If employment today – the work relationship – allows the realisation of these two sides to the social link, it means that it integrates elements which deal with neither the act of work, nor the product of work. But it acts in such a way as to import a dimension of production to the sociability, to reduce the latter to a means to an end: the preservation of a society of employment.

Arsenic is one of the materials that has a worldwide concern because of its high toxicity and chronic effects on human health. The existence of arsenic as As (III) is about 56 times poisonous as As (V) and more difficult to process. The investigation takes the pyrite as an adsorbent to remove As (III) from waste water. Different morphology and granularity of pyrite were synthesized by hydrothermal and liquid-phase precipitation methods, respectively. The findings show that the addition of pyrite nanoparticles to the solution provided highest As (III) removal efficiency of 88.53%. 1 gL−1 pyrite nanoparticles can reduce the concentration of arsenite in the waste water from an initial As content of 30 mgL−1 to 3.4 mgL−1 at pH 11. Under the similar operating conditions, the synthetic micropyrite and natural pyrite have a lower As (III) removal; both were less than 70%. In addition, the synthetic pyrite nanowires obtained 86.70% removal efficiency of arsenite. The results confirmed that the morphology and granularity of pyrite can significantly influence the adsorption of arsenite removal from aqueous solution.


A diode-pumped Q-cw (quasi-continuous wave) with simultaneous dual-wavelength laser operation at 744.8 nm and 860.9 nm in a single Ti: sapphire crystal is demonstrated. The birefringent filter is employed as the tuning apparatus for its low loss. A total output power of 4.8 W at the two wavelengths was achieved at the incident pump power of 23 W. To our knowledge, this is the highest value of the all-solid-state quasi-continuous dual-wavelength lasers which employ the Ti: sapphire as the gain medium.


Abstract Three dominant legume species (Tephrosia virginiana (L.) Pers., Rhynchosia reniformis DC., and Centrosema virginianum (L.) Benth.) found in frequently burned longleaf pine woodlands were grown in a garden plot and treated with a factorial arrangement of shade treatments (±) and burning (±) treatments. Nitrogen fixation was measured using 15N Isotope dilution method with whole plant recovery (including root systems). Burning treatments decreased total biomass (P < 0.001) and increased root to shoot ratios (P < 0.001). N2-fixation rates were generally reduced by burning, but there was a complex interaction among species, shade, and burn treatments. For Tephrosia, contrasts of shade (F1,42 4.48, P < 0.05) and burn (F1,42 4.42, P < 0.05) indicate that both main treatment effects significantly reduced N2-fixation rates. Relative to all other treatment combinations, Rhynchosia had elevated levels of N2-fixation under the no shade by burn treatment. Centrosema showed no effect of shade on N2-fixation (F1,42 1.65, P > 0.05), but burns significantly lowered N2-fixation rates for both shaded and unshaded plants (F1,42 19.31, P < 0.001). Despite the diverse response of species N2-fixation activity to treatments, a regression of all individuals regardless of species shows a curvilinear relationship of % N derived from the atmosphere to total plant biomass. The diverse response of these herbaceous legumes to light and fire challenges the conventional wisdom that legumes maintain functional redundancy as a guild across environmental gradients within longleaf pine woodlands.


Opinions are used to express views and reviews are used to provide information about how a product is perceived. People contributions lie in posting text messages in the form their opinions and emotions which may be based on different topics such as movie, book, product, and politics and so on. The reviews available online can be available in thousands, so making the right decision to select a product becomes a very tedious task. Several research works has been proposed in the past but they were limited to certain issues discussed in this paper. The reviews are collected which periodically updates itself using crawler discussed in our previous work. Further after applying certain preprocessing tasks in order to filter reviews and remove unwanted tokens, the sentiments are classified according to the novel unsupervised algorithm proposed. Our algorithm does not require annotated training data and is adequate to sufficiently classify the raw text into each domain and it is applicable enough to categorize complex cases of reviews as well. Therefore, we propose a novel unsupervised algorithm for categorizing sentiments into positive, negative and neutral category. The accuracy of the designed algorithm is evaluated using the standard datasets like IRIS, MTCARS, and HAR.


The design of optimum air-heating vaporizer is needed to compensate for the low heat capacity of air as its heat source. In this study, numerical analysis of air heating vaporizer is conducted. A longitudinally-finned vertical-pipe was used as CFD model to represent the air-heating vaporizer. Cryogenic nitrogen was used as the working fluid and the ambient air was assumed to contain no water vapor. The convective heat transfer coefficient inside the pipe (hi) which is derived from CFD analysis has a good agreement with the convective heat transfer coefficient derived from Perkins' Nusselt correlation. Then, the convective heat transfer coefficient outside the pipe (h o ) was calculated and then it was continued to find the relation between the Rayleigh (Ra) number and Nusselt number outside the pipe, Nu o . The results show that the Ra number and Nu o number have proportional trend in the range of Raleigh number of 1.3674×10¹³≤Ra≤2.8343≤10¹³ and then the Nusselt number correlation outside the pipe, Nu o , was proposed.

In wireless communication system, the receiver side Bit error ratio (BER) strongly affected by channel error, interference, distortion, synchronization error and wireless multipath fading channels. Multiple-input and multipleoutput, (MIMO ) is the use of multiple antennas at both the end in wireless communication to improve Bit error ratio (BER) performance. In this paper, has been performed evalution of QAM-OFDM with transmission schemes. This model is used for performance evaluation of the OFDM with QAM modulation schemes and fading channel. The throughput and packet error rate are used to evaluate the performance of MAC layer with the change in physical layer parameter, the using FEC code. The results has been shown in the paper for the simulation in various condition.


The phenomenon of intermodulation generation due to passive components is generally called passive intermodulation (PIM for short).In high power multichannel communications systems, once PIM product falls within receiving frequency band, it can become one of the spurious interference. This paper simplifies PIM problem assumption of composite interference model and characteristic function method.An analysis is made of the statistical properties of total interference including PIM interference.Furthermore,a numerical simulation is carried out to the effects of PIM on the anti noise property of communications systems,which provides important reference for designing communications systems. Analytical and simulated results show that tail distribution is very different from Gaussian and the effects of passive intermodulation interference on communication systems are mainly in region of low bit error rates.


Audre Lorde likes to refer to herself as black, lesbian, feminist, mother, poet, and warrior. Later in life, she also identifies herself as a survivor of cancer. She refuses absolutely to confine herself, even temporarily, to any one aspect of her heterogeneous identity, whether to support a political program or to make others feel comfortable. And each part of the self she constructs is based on a sense of corporeal materiality that she attempts to render in both her prose and poetry. Her writing calls to mind Rosi Braidotti's vision of the embodied self. In Patterns of Dissonance: A Study of Women in Contemporary Philosophy, Braidotti explains, "The body, far from being an essentialist notion, is situated at the intersection of the biological and the symbolic; as such it marks a metaphysical surface of integrated material and symbolic elements that defy separation." 1 When speaking of Lorde's use of embodiment to reverse the balance of power between the oppressed body and the written text, we must ask how the body relates to a text. On the one hand, there is no way to discuss the body as prior to sign without resorting to signification. On the other hand, in Bodies That Matter: On the Discursive Limits of "Sex," Judith Butler reminds us of the materiality of the signifier itself, for materiality and signification are indissoluble.2 As a writer, Lorde is acutely aware of this indissolubility. She perceives her body as a text and is conscious of her texts as emerging from her body. Although embodying oneself and naming one's subject positions are not perfectly synonymous, they overlap in Lorde's writing because of her awareness of her presence in Western society as both experience and sign. Writing about The Cancer Journals, Jeanne Perrault applies the idea of the embodied self to Lorde's work, expressing her belief that Lorde creates "a writing of self that makes the female body a site and source of written subjectivity, yet inhabits that body with the ethics of a deeply and precisely historical, political, sexual, and racial consciousness." 3 In Lorde's writing, the conjunction of body,


Radiation‐induced brain injury (RBI) usually occurs six months to three years after irradiation, often shows cognitive dysfunction, epilepsy, and other neurological dysfunction. In severe cases, it can cause a wide range of cerebral edema, even herniation. It seriously threatens the survival of patients and their quality of life, and it becomes a key factor in limiting the radiation dose and lowering the therapeutic efficacy in recent years. Therefore, studying the pathogenesis of RBI and exploring new therapeutic targets are of great significance.

The new edition of this substantially enhanced and superbly illustrated "classic" textbook encompasses detailed and authoritative descriptions of our current understanding of disease mechanisms and their pathologic sequelae. As in previous editions, the book is organized into two major sections of unequal length. The first one-third encompasses 10 chapters dealing with molecular, cellular, and tissue reactions to injury caused by agents and/or pathophysiological processes that may affect any organ system, e.g., infections or environmental agents, nutritional deficiencies, vascular or immunologic reactions, and neoplasia. The remaining two-thirds of the book consists of 20 chapters describing etiologic mechanisms, pathologic lesions, diagnostic tests, when appropriate, and clinicopathologic correlations of diseases affecting specific organs or organ systems. Between the two sections, a substantially improved chapter on diseases of infancy and childhood has been …


A printed, planar multi‐loop‐antenna system having high‐gain, quasi‐dual‐polarized radiation properties for concurrent, dual‐band WLAN operation in the 2.4 and 5.2 GHz bands is presented. The multi‐antenna design comprises four printed loop antennas arranged to be of a orthogonal configuration, printed on the same‐layer of a 1.6‐mm thick FR4 substrate, and one system PCB serving as an efficient reflector for the loops. The four antennas are set within the boundary of the PCB of the typical size for compact, outdoor access‐point (AP) applications and stacked there above by a small distance. In this study, the design integrates the system PCB of an AP into an internal multi‐antenna solution for compact outdoor APs. The results show that good input matching with 10‐dB return loss over the 2.4 and 5.2 GHz bands can be attained. Directional radiation patterns with comparable Eθ and Eφ fields were also obtained. © 2010 Wiley Periodicals, Inc.

Introduction. Traditionally, the hygienic assessment of working conditions when using glyphosate preparations, an extremely popular herbicide in the world, is based on the use of thin layer chromatography. In this paper, alternative approaches are considered. On the basis of experimental data, the conditions for the analysis of glyphosate content in air by high performance liquid chromatography were optimized. Material and methods. All work with glyphosate solutions was carried out in polypropylene vessels. Sampling from the air medium was carried out on a medium filtration filter ("blue ribbon"). Subsequent extraction was carried out with water. The measurements were performed by high performance liquid chromatography with a fluorimetric detector at an excitation wavelength of 270 nm and an emission wavelength of 313 nm. To transfer glyphosate to a molecule with fluorimetric properties after derivatization of glyphosate in an alkaline medium using 9-fluorenylmethyl chloroformate by heating and washing off the excess of the reagent with toluene. A C18 reverse phase column was used; ammonium acetate with the addition of acetic acid and acetonitrile were used as eluents. Results. Approbation of the developed technique was carried out on real samples taken during ground treatment of fallow fields and lands of industrial territories with glyphosate preparations. The detected levels of glyphosate did not exceed the lower limit of quantitative determination: 0.5 mg/m3 in the air of the working area and 0.025 mg/m3 in the atmospheric air (with maximum allowable concentrations of 1.0 and 0.1 mg/m3, respectively). Limitations. The study considers a limited number of chromatographic columns. The study is performed on 25 model samples of the air of the working area and atmospheric air. Conclusion. Based on the results of the work performed, methodological instructions "Measurement of glyphosate concentrations in the air by high-performance liquid chromatography" were formed and sent for metrological certification in the approved manner.


Background: quality of life of cancer survivors is adversely impacted by bowel toxicity; result from pelvic radiation therapy. In the UK, 12000 patients are treated with radiation therapy for pelvic cancer, mostly with curative intent; this carries a considerable risk for normal surrounding tissues side effects.Objective: the aim of this study was to determine the frequency, types and grade of acute gastrointestinal toxicity in radical pelvic radiation therapy in our patients so that a comparison could be made with the Western countries.Patients and Methods: a prospective analytic study was carried out in Radiotherapy department / Oncology teaching hospital / Medical city complex, from the 2nd of January to the 30th of April 2016. A total of 53 patients with histologically confirmed uterine, cervical, rectal, urinary bladder or prostatic cancer, treated by radical radiation therapy, were enrolled in the study. Patients were assessed for the frequency, types and grade of acute gastrointestinal toxicities according to grading criteria of CTC (Common Toxicities Criteria), at the start, during and at the end of the treatment. The data was analyzed by the Statistical Package for Social Sciences (SPSS 20).Result: out of 53 patients, 60.37% (32) were female and 39.62% (21) were male. Endometrial cancers represent 30.18% of the cases, cervical cancers were 24.52%, and rectal cancers 11.32%, urinary bladder cancers 24.52% and prostatic cancers were 9.43% of the total cases. Diarrhea was present in 50.9% of the patients; nausea and vomiting were present in 22.6% for each. The majority had grade 1 toxicities and only 2 patients developed grade 3 diarrhea (4.7%).Conclusion: The type and incidence of acute gastrointestinal toxicities in pelvic radiation therapy were mostly related to; Radiation dose, a combined used of chemotherapy with radiation therapy and surgery.


This paper presents results obtained by applying periodic clock changes multiple access (PCCMA) to the uplink of mobile multiuser communication systems. Emitted signals are subjected to periodic clock changes based on linear time variant filters. At the reception side, we transpose the system in the time invariant domain and apply inverse filtering.


Since many of the quantitative plant characters of economic values are highly influenced by environmental condition, the progress in breeding in such a population is primarily conditioned by the magnitude, nature and inter-relations of genotypic and non-genotypic variations in plant characters. Therefore we estimated phenotypic, genotypic and environmental correlation coefficients and path coefficients among eight quantitative traits of bread wheat to make selection efforts more efficient. These traits were measured in 30 wheat genotypes, which were laid out in a randomized block design with three replications in Khumaltar, Kathmandu during 2003. The highest genotypic correlation (0.81) was between heading and maturity days. Tiller number was negatively correlated with grain number per spike (-0.78) at genetic level. Phenotypically, number of grains and grain weight per spike showed the largest coefficient (0.92) and maturity days exhibited negative association with plant height (-0.37). Environmental correlation coefficient was the highest between tillers number and grain yield (0.5) and heading days showed negative relationship with grain yield (-0.28). It indicates that number of tiller and grains per spike are the most important traits for yield. In most of the cases, genotypic correlations were higher than phenotypic correlations. Maturity days exerted the greatest influence (2.41) directly upon yield. Negative direct effect of heading days and positive effect of tiller number on yield was also considerable on magnitude. Indirect effect of heading days via maturity days was the highest followed by spike grain weight via maturity on grain yield. Results showed that grain filling period is an important factor and number of tillers and grains per spike should also be considered during selection for getting high yielding genotypes.

We describe a very simple technique for obtaining an instantaneous display of the electron energy distribution in a plasma. We electronically doubly differentiate the current‐voltage characteristic of the Langmuir probe, following the method of Druyvesteyn. In our technique, we use operational amplifiers for differentiation. Our new contributions are: First, we have discovered where the noise is produced that formerly made operational amplifiers unsatisfactory; second, we have demonstrated that this noise can be eliminated; and third, we have produced simple techniques for cross checking our double‐differentiating system to demonstrate that the noise‐elimination process does not appreciably distort the desired information.


This paper is devoted to studying the statistical approximation properties of a sequence of univariate and bivariate blending-type Bernstein operators that includes shape parameters α and λ and a positive integer. An estimate of the corresponding rates was obtained, and a Voronovskaja-type theorem is given by a weighted A-statistical convergence. A Korovkin-type theorem is provided for the univariate and bivariate cases of the blending-type operators. Moreover, the convergence behavior of the univariate and bivariate new blending basis and new blending operators are exhaustively demonstrated by computer graphics. The studied univariate and bivariate blending-type operators reduce to the well-known Bernstein operators in the literature for the special cases of shape parameters α and λ, and they propose better approximation results.


At present, for most LHC type physics beams, six buckets of the PS operated with harmonic number h=7 are filled in two transfers, and each of the PS Booster rings provides only one bunch. The scheme presented aims at replacing the double batch transfer by a single batch transfer and is of interest (i) for the nominal 25 ns LHC beams once the Booster injection energy has been increased after completion of Linac4 and (ii) already now for 50 ns and 75 ns LHC beams less demanding for the Booster in terms of beam brightness. Two bunches with the correct spacing must be generated in the Booster rings by superposition of an h=2 RF system and a smaller h=1 component. Theoretical considerations and first experimental results will be presented.

A highly efficient protocol for the induction of callus and establishment of cell suspension culture was developed for Actinidia deliciosa. Germination of Actinidia seeds were carried out on full strength MS medium without any growth hormone and the leaves from In vitro grown plantlets were used for the induction of callus. Maximum amount of friable calli were obtained on full strength MS medium supplemented with 1.0 mg/L IBA (Indole-3-butyric acid) and 0.5 mg/L BAP (6-Benzyl amino purine) with the 16 hrs illumination period. Cell suspension cultures were established using MS medium with higher amount of IBA (2.0 mg/L) and BAP (0.5 mg/L), by rotating the culture flasks at 110 rpm on a gyratory shaker. Biotransformation ability of the suspension culture of Actinidia deliciosa was also determined by adding (-)-Ambrox to the cultures as a substrate. Six transforms were isolated after 15 days of incubation while two of them were found novel.


Coronavirus disease-2019 (COVID-19) has disrupted cancer care services globally. The present review of cause of deaths was conducted in a tertiary care cancer center in the North East India. In our institute, all cancer patients requiring admission for surgery, chemotherapy, and other daycare procedures require testing for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). From 09 July 2020 to 16 May 2021, 119 cancer patients with SARS-CoV-2 positive report or COVID-19 have been admitted at our institute Covid ward. A total of 19 cancer patients with COVID-19 succumbed. Of 19 deaths, 13 (68.4%) patients were men and 6 (31.6%) patients were women. The age range from 27 years to 74 years (median =55 years). Vomiting alone or with diarrhea was the most common symptom requiring admission after testing (4/19, 21.0%), followed by bleeding from primary tumour site (3/19, 15.7%). The antecedent and underlying cause of deaths in 19 (100%) patients was cancer. SARS-CoV-2 infection should not be a hindrance for cancer treatment and management.


Trust in "green" practices emerges as a crucial determinant in consumer decision-making, reflecting the value placed on a hotel's sustainability endeavors. This study investigates the factors influencing trust in green hotels by analyzing demographic data obtained from 172 participants in Latin America. Employing statistical methods, including ANOVA and SEM, the research explores the relationship between trust in green practices and demographic variables, with a focus on identifying potential significant differences. The findings highlight the pivotal role of age, particularly the 18–24 years old, in fostering greater environmental commitment. Additionally, the study reveals that prior experience, knowledge, and commitment significantly explain green trust levels. This study offers insights into the Latin American consumer profile, thereby aiding hoteliers and environmental practitioners in comprehending consumer behavior toward eco-friendly lodging options.


Objective To evaluate the expression of μ opioid receptor of the knee joint synovium tissue in patients with chronic inflammation. Methods The patients were divided into inflammatory group and control group(n=25 for both). Those who were allocated to the inflammatory group were diagnosed as osteoarthritis by arthroscopy, and in the control group, the patients were having dislocation of patella and took internal fixation with arthroscopy. The synovium tissues were harvested from suprapateller bursa, articulation vestibule, intercondylar fossa and articulation metacele. The synovium were taken to measure μ opioid receptor by immunohistochemistry and RT-PCR in both groups. Results Immunohistochemical and RT-PCR results revealed that the expression of mRNA and the optical density (OD) of immunoreaction of μ-opioid receptor in the knee synovium tissue in the chronic inflammation group were significantly higher than those in the control group (P0.05). There was no significant difference in the expression of mRNA and the OD of immunoreaction of μ-opioid receptor in the four parts of knee synorium tissue in each group (P0.05). Conclusion The expression of μ opioid receptor of the knee joint synovium tissue in chronic inflammation was significantly up-regulated. It may play a partial role in the peripheral mechanism of morphine.

Superconductors and in particular superconducting tunnel junctions can be used to detect phonons, electromagnetic radiation, x rays, and nuclear particles by the mechanism of Cooper‐pair breaking to produce excess quasiparticles and phonons. We show that the sensitivity can be increased by a factor of 100 or more by trapping the quasiparticles in another superconductor of lower gap in the region of the tunnel junction. Moreover, if the ratio of the gap energies is >3 a multiplication process can occur due to the interaction of the relaxation phonons. This leads to the concept of the quasiparticle multiplier, a device which could have wider applications than the Gray effect transistor or the quiteron.


Traditional cognitive psychology relies on concepts bordering idealism, an issue that has been known since the end of the 19th century. At best, the underlying assumptions are misleading and do not bring us closer to an understanding of human enterprise. Also, psychology in general is not a unified paradigm; its sub-disciplines rely on different conceptual bases. Ecological Psychology can change that. Getting rid of the non-sequitur "it is all in the brain" is a start and not that controversial, but, this is simply a stepping stone to a complete change in perspective. Organisms are born into an ever-changing environment, which they constantly interact with, perceive themselves in, constantly change and are changed by. An attempt is made to contrast computational and ecological assumptions about how the brain works by having participants intercept an object on a computer screen. Hypothesis is that participants will favour an ecological strategy over a computational. Results speak in favour of reliance on ecological assumptions rather than computational and also indicates that representations may not be necessary even for objects that are temporarily imperceptible.


In this paper, we describe the biochemical properties and biological activity of a series of cholinesterase reactivators (symmetrical bisquaternary xylene-linked compounds, K106-K114) with ctDNA. The interaction of the studied derivatives with ctDNA was investigated using UV-Vis, fluorescence, CD and LD spectrometry, and electrophoretic and viscometric methods. The binding constants K were estimated to be in the range 1.05 × 10(5)-5.14 × 10(6) M(-1) and the percentage of hypochromism was found to be 10.64-19.28% (from UV-Vis titration). The used methods indicate that the studied samples are groove binders. Electrophoretic methods proved that the studied compounds clearly influence calf thymus Topo I (at 5 μM concentration, except for compounds K107, K111 and K114 which were effective at higher concentrations) and human Topo II (K110 partially inhibited Topo II effects even at 5 μM concentration) activity.


A frequency estimator is to find the frequency of the received signal distorted by noise, and it has been found in systems such as radar, sonar, etc. In this research, the linear frequency modulation signal(LFM)of the radar system, the detection of the moving target and its frequency estimation were highlighted. The pre-trained convolutional neural network algorithm was used, which proved highly accurate in detecting the target and estimating its frequency, despite the lower level of the signal to the noise ratio(SNR) where it was dealt with. On the basis of the signals received as a two-dimensional image and taking into account the Doppler effect, as the target moves at different speeds and accelerations, the signals have been classified into single-frequency signals and LFM signals


To reduce the computation cost, Deriche (1987, 1990) extended the work from Canny (1986) on optimal edge detectors to the use of recursive filters. Nevertheless, this cost is still too high for real time implementation on FGGA circuits. Here, we optimized both the algorithmic and architectural aspects of the original Deriche filter. A new organization of the filter is proposed at the 2D and 1D levels which reduces the memory size and the computation cost by a factor of two for both software and hardware implementations. We prove that the use of only 3 bits to code the scale parameter does not reduce the quality. The result from this choice is that the first order recursive filter which is the basic block of the entire architecture can be built with only 4 adders. The architecture of a 10 Mpixels/second filter on an unique FPGA is described.

The Heart and Stomach of a King: Elizabeth I and the Politics of Sex and Power Second edition, by Carole Levin. 2014. University of Pennsylvania Press, Philadelphia. Pp xx + 264. Includes 12 illustrations and index. $27.50 paperback. ISBN 978-0-2240-1 In the twenty years separating the initial publication of Carole Levin's The Heart and Stomach of a King in 1994 from the second edition under review here, Queen Elizabeth I has been, according to Wikipedia, the subject of two Hollywood films (Elizabeth (1998) and Elizabeth: The Golden Age (2007), both starring Cate Blanchett), two BBC miniseries (The Virgin Queen (2005) with Anne-Marie Duff and Elizabeth I (2005) with Helen Mirren), and has appeared in smaller roles in several films, television shows, works of fiction, and video games; she even has a Twitter hashtag (#queenelizabethI). For an English monarch who has been dead for more than 400 years, Elizabeth I (1533-1603; reigned 1558-1603) continues to hold a powerful sway over both the popular and the academic imagination in the 21st century. For Levin, the key to Elizabeth's fascination lies in the two terms she highlights in her subtitle: sex and power. Elizabeth I successfully ruled England for 45 years as an unmarried woman, something unparalleled by any other female ruler of the period but also a source of cultural anxiety: Elizabeth along with her sister Queen Mary I (reigned 1553-1558) were the first women to be crowned Queen of England since the Norman Conquest in 1066. Elizabeth I remains a significant figure for us today not only as a resource for popular culture but also because, as Levin notes, despite our many differences from sixteenth-century England, women in positions of power still face difficulties that do not trouble their male counterparts. Levin points to Hillary Clinton and Sarah Palin in the United States, Michelle Bachelet in Chile, Angela Merkel in Germany, and Ellen Johnson Sirleaf of Liberia as examples of contemporary women in power behind whom "we perhaps can see the shadow of a long-dead queen" (xvi). Levin's work is not a biography in the traditional sense. In her Preface to the Second Edition, Levin prefers the term "cultural biography" for her project. Inspired by the "poetics of culture" model offered by Stephen Greenblatt's Renaissance Self-Fashioning, Levin's Heart and Stomach of a King goes beyond the facts of Elizabeth's life to consider "how Elizabeth represented herself and how people in turn responded to her as an unmarried woman in power" (xiii), looking not only at conventional historical sources but also at how Elizabeth was constructed socially in gossip, in rumors, in slander, and even in dreams. Levin begins with a brief Introduction outlining Elizabeth's life prior to assuming the throne in 1558 as well as some of the basic challenges Elizabeth faced as a woman in a position of power. Some of Levin's central questions include "how did [Elizabeth] transcend her gender and her unmarried, childless state, and in what ways was she trapped by it? What strategies did she use that were successful and which ones failed? What were the different ways in which her people responded to her? How did the image of the queen change in the reign of her successor, James I?" (4). The remaining chapters proceed in approximate chronological order and skilfully weave together the biographical and cultural elements of this cultural biography. Chapter 2, "Elizabeth as Sacred Monarch" focuses on Elizabeth's engagement with religion. As monarch, Elizabeth gained authority over the English church, but Parliament in 1559 was reluctant to grant her the title "Supreme Head" of the Church, the title held by her brother, Edward VI, and her father, Henry VIII. As the Archbishop of York explained, "Her highness, beyinge a woman by birthe and nature, is not qualyfied by God's worde to feed the flock of Chryst, it appeareth most playnley.... Therefor she cannot be supreme head of Christ's militant churche" (14). …


AIM: To evaluate whether semen processing at 37°C yield sperm with better DNA integrity compared to centrifugation and processing at room temperature (RT) by swim-up method. SETTINGS: This study was done at tertiary care center attached to Reproductive Medicine Unit and Medical College. DESIGN: Prospective pilot study. PATIENTS: Normozoospermic men (n = 50) undergoing diagnostic semen analysis. MATERIALS AND METHODS: Normozoospermic samples (World Health Organization, 2010 criteria) after analysis was divided into two aliquots (0.5 mL each); one was processed at 37°C and the other at RT by swim-up method. DNA fragmentation of both samples post wash was calculated by acridine orange method. STATISTICAL ANALYSIS USED: The values of sperm DNA fragmentation were represented as mean and standard error (mean ± SEM) of the mean. Paired t-test was used for calculating the sperm DNA integrity difference between post wash at RT and 37°C. RESULTS: Statistically significant difference was not observed in post wash sperm DNA fragmentation values at 37°C compared to RT. CONCLUSION: Our data represents that there was no significant difference in sperm DNA fragmentation values of samples processed at 37°C and at RT. Hence, sperm processing at 37°C does not yield sperm with better DNA integrity compared to centrifugation and processing at RT.

This paper describes the hardware and software ecosystem encompassing the brain-inspired TrueNorth processor – a 70mW reconfigurable silicon chip with 1 million neurons, 256 million synapses, and 4096 parallel and distributed neural cores. For systems, we present a scale-out system loosely coupling 16 single-chip boards and a scale-up system tightly integrating 16 chips in a 4 × 4 configuration by exploiting TrueNorth's native tiling. For software, we present an end-to-end ecosystem consisting of a simulator, a programming language, an integrated programming environment, a library of algorithms and applications, firmware, tools for deep learning, a teaching curriculum, and cloud enablement. For the scale-up systems we summarize our approach to physical placement of neural network, to reduce intra- and inter-chip network traffic. The ecosystem is in use at over 30 universities and government/corporate labs. Our platform is a substrate for a spectrum of applications from mobile and embedded computing to cloud and supercomputers.


The article describes functional and semantic features of the words with the stem жи(ть) in the poetry of one of the less known and prohibited for a long time representative of the Silver century Nikolay Kluev. In the poetry of N. Kluev we come across a lot of words, which are not used now and nearly forgotten: dialect, religious, out of date. We find it important to study the functional and semantic properties of this ancient Indo-European stem in the metaphoric allegoric language of N. Kluev.


Crystal structure and transport properties of the mixed praseodymium cobaltites-ferrites PrCo1−xFexO3 have been studied in the temperature range of 298–1173 K by a combination of in situ X-ray synchrotron powder diffraction and temperature dependent impedance spectroscopy measurements. In situ high temperature powder diffraction examination of PrCo1−xFexO3 series revealed considerable anomalies in the lattice expansion which are especially pronounced for the cobalt-rich specimens. These anomalies, which are reflected in a sigmoidal dependence of the unit cell dimensions and in the considerable increase of the thermal expansion coefficients, are obviously associated with transitions of Co ions from low spin to the higher spin states and the coupled metal–insulator transitions, occurring in in rare earth cobaltites at the elevated temperatures. Indeed, the temperature-dependent impedance measurements clearly prove the change of conductivity type from dielectric to the metallic behaviour in the mixed cobaltite-ferrites PrCo1−xFexO3 at the elevated temperatures.


The "APC3RH" is a 16 channel CMOS analogue buffer chip designed to facilitate the readout of silicon diode based particle detectors. It is a radiation hard successor to the "APC3 chip". Each channel consists of a fast pre-amplifier, integrator, 160 storage capacitors and a readout amplifier. The amplified current from the detector is integrated continuously, the resulting charge being stored every 25 ns on one of the capacitors. An on-chip control system selects another capacitor to store charge at the end of each integration period, avoiding those which are being read out or which contain charge destined to be read out. Charges are held on the capacitors until they are connected to the readout buffer or overwritten by new data, depending on the value of an external signal. The storage and reading cycles run concurrently. The on-chip buffer control circuitry ensures that data is read out in the chronological order of storage. The chip has been fabricated using a radiation hard technology capable of withstanding 10 Mrad. This paper describes its design and also the results of testing, the latter before and after irradiation. The purpose of the design was to evaluate the Harris AVLSIRA radiation hard process suitability for LHC applications. In this paper the performance of the design is compared with that of its non "rad hard" predecessor the APC3. Also the results of measurements made on the performance of the chip before and after irradiation are presented.<<ETX>>


CPNS' new Working Paper examines the latest findings from a national survey of professional advisers on the topic of philanthropy assistance to high-net-worth individuals. Findings confirm a growing willingness within the Australian advisory sector to provide philanthropy advice to clients with means, although the rate of change has slowed since 2005. Advisers are now more likely to see benefits in providing this type of counselling, as well as benefits for their clients in engaging in philanthropy.
