Lead was suggested as an etiological factor in multiple sclerosis by Putnam. 1 Cone, et al., 2 examined a series of 40 spinal fluids for lead, using the qualitative hexanitrite test of Fairhall. 3 In their series were 8 patients with multiple sclerosis. In 6 of these the tests for lead were positive. Rabinowitch, et al., 4 about the same time reported the results of tests of 50 spinal fluids, including those from 27 cases of multiple sclerosis. These authors used the Fairhall hexanitrite method and checked their results by spectographic determinations. These authors found positive tests for lead in only 2 of their 27 cases of multiple sclerosis; in 2 additional cases they obtained positive tests after administering ammonium chloride to their patients. Boshes 5 tested 28 specimens of spinal fluid for lead, by the same method. Sixteen of his patients had multiple sclerosis; in only one of these did the spinal fluid yield a positive test for lead. All the above authors found occasional positive tests for lead among their control cases. Because the above findings depended on a qualitative test that is difficult to control, we believed it would be worth while to investigate the lead content of a series of spinal fluids, using a precise quantitative micro-chemical method. Such a method has been devised by Wilkins, et al. 6 This method involves the titrimetric extraction of lead with a standard solution of diphenylthiocarbazone in the presence of ammoniacal cyanide. The original method was designed for use with blood; we have adapted it to spinal fluids in the manner described below. Lumbar puncture was done with a dry, sterilized needle, and the fluid allowed to drop directly into a lead-free Pyrex flask. A measured volume of fluid, varying from 25–50 cc. was transferred to a Pyrex evaporating dish, and evaporated to dryness on a steam bath. The Pyrex dish was then transferred to an electric muffle furnace and ashed for 16 hours at 450°C. The ashed sample was dissolved in warm 5% nitric acid and transferred to a Pyrex separatory funnel, in which the titrimetric extraction was carried out. Simultaneous blanks were run with each set of determinations.

The protected cyclopentanecarboxylic acids (6) and (14), obtained from 8,9,10-trinorborn-5-en-2-ol, are useful intermediates for the synthesis of carbocyclic ribo- and 2′-deoxyribo-C-nucleoside analogues. This is exemplified by their conversion into the imidazo[1,5-a]pyridine carbocyclic C-nucleosides (18) and (22).

Downward turbulent bubbly flow in pipes was numerically studied. A bubble population balance model (BPBM) has been incorporated into computational fluid dynamics (CFD) and drag force, lift force, wall lubrication force and turbulence dispersion forces are considered into account. Flow parameters for liquid single phase and two-phase air-water bubbly flow in a 57.15 mm diameter and 3.06 m length vertical pipe were predicted. CFD-BPBM model predictions are in good agreement with experimental data.


In all digital communications, knowledge of the propagation channel between the transmitter and the receiver is essential. For transmitting of data through solid bodies, such as metal plates, pipe walls, etc., ultrasound is a viable alternative to radio communication and wired transmission. In ultrasound communication, the channel consists of two parts, the combined response of the transducers used as transmitter and receiver, and the impulse response of the propagation medium itself. For a thin plate with parallel surfaces, this results in a reverberating channel that significantly reduces the achievable bitrate if not handled properly. In this paper we show with simulations how the bit-error rate in Orthogonal Frequency Division Multiplexing (OFDM) communications, is affected by the reverberating nature of the plate, and how this can be overcome by the introduction of a channel shortening filter placed in front of the OFDM conventional receiver. The results show that this significantly reduces the bit-error rate, especially for thin plates. If the reverberations instead were to be compensated by the conventional channel equalization method in OFDM, we show that for the example in the simulations, the bitrate would drop by almost 25 %, from about 3.9 Mbit/s to about 2.9 Mbit/s.

Ten participants (5M, 5F) completed 3 × 30‐min bouts of exercise (Ex 1, 2, 3) at a metabolic heat load (M‐W) of 505±7 W separated by 3 × 15‐min recovery (Rec 1, 2, 3) in an air calorimeter at 30°C, 30% RH. Rates of evaporative heat loss (EHL), dry heat loss (DHL) and M‐W were measured throughout by whole‐body direct calorimetry, giving changes in body heat content (ΔHb). Rectal (Tre), quadriceps (Tquad) and triceps (Ttri) temperature were measured throughout. ΔHb progressively increased from the end of Ex 1 (242±18 kJ) to end Ex 2 (308±29 kJ), to end Ex 3 (341±46 kJ). Heat content dissipated during Rec 1 (−63±10 kJ) was similar to Rec 2 (−74±9 kJ) and Rec 3 (−73±7 kJ). Tre progressively increased from 36.88±0.11°C at rest to 37.41±0.12°C at the end of Ex 1, 37.64±0.12°C (Ex 2), and 37.74±0.12°C (Ex 3). Ttri increased from 33.91±0.19°C at rest, to 34.86±0.25°C (Ex 1), 35.23±0.28°C (Ex 2), and 35.40±0.33°C (Ex 3). However, after an initial increase in Tquad from 34.62±0.14°C at rest to 36.82±0.16°C (Ex 1), no further significant elevations were observed. DHL was between ~50 and 65 W throughout. At the end of Ex 1 (383±25 W), Ex 2 (398±9 W) and Ex 3 (413±9 W) EHL was similar; however EHL increased at a greater rate during Ex 2 and 3 relative to Ex 1. Progressive elevations in body heat content, core temperature and inactive muscle temperature occurred with intermittent exercise.


The Schrödinger-Virasoro Lie algebra sv is an extension of the Virasoro Lie algebra by a nilpotent Lie algebra formed with a bosonic current of weight 3 2 and a bosonic current of weight 1. It is also a natural infinite-dimensional extension of the Schrödinger Lie algebra, which – leaving aside the invariance under time-translation – has been proved to be a symmetry algebra for many statistical physics models undergoing a dynamics with dynamical exponent z = 2 ; it should consequently play a role akin to that of the Virasoro Lie algebra in two-dimensional equilibrium statistical physics. We define in this article general Schrödinger-Virasoro primary fields by analogy with conformal field theory, characterized by a 'spin' index and a (non-relativistic) mass, and construct vertex algebra representations of sv out of a charged symplectic boson and a free boson and its associated vertex operators. We also compute twoand three-point functions of still conjectural massive fields that are defined by an analytic continuation with respect to a formal parameter.

We study the physical properties of a ballistic heterostructure made of a ferromagnet (FM) and a spin-triplet superconductor (TSC) with a layered structure stacking along the direction perpendicular to the planes where a chiral px+ipy pairing occurs and assuming spin dependent processes at the interface. We use a self-consistent Bogoliubov-de Gennes approach on a three-dimensional lattice to obtain the spatial profiles of the pairing amplitude and the magnetization. We find that, depending on the strength of the ferromagnetic exchange field, the ground state of the system can have two distinct configurations with a parallel or anti-parallel collinearity between the magnetic moments in the bulk and at the interface. We demonstrate that a magnetic state having non coplanar interface, bulk and Cooper pairs spins may be stabilized if the bulk magnetization is assumed to be fixed along a given direction. The study of the density of states reveals that the modification of the electronic spectrum in the FM plays an important role in the setting of the optimal magnetic configuration. Finally, we find the existence of induced spin-polarized pair correlations in the FM-TSC system.


Two-yr-old Norway (Picea abies (L.) Karst.), red (P. rubens Sarg.), black (P. mariana (Mill.) B.S.P.) and white (P. glauca (Moench.) Voss) spruce seedlings were exposed from bud break for 35 or 63 d (4·5 h irradiance d−1) to a gradient of biologically effective u.v.-B radiation (λ=280–315 nm) ranging from 0·61 kJ m−2 d−1 to 5·99 kJ m−2 d−1. No visible symptoms of u.v.-B injury were observed. Epicuticular wax production was not affected by needle exposure to increasing u.v.-B irradiance. Seven constituent classes were resolved by GC and confirmed by GC–MS in wax recovered from needles of the four species. Wax composition of Norway, black and red spruce was altered following needle exposure to increasing u.v.-B dose. White spruce wax composition was unaffected. Direction and magnitude of wax composition response was species-dependent. The proportion of nonacosane diols on Norway spruce needles increased (P<0·05) whereas that of alkyl esters decreased with increasing u.v.-B dose. The proportion of fatty acids in black spruce needle wax increased (P<0·05), and that of estolides (GC-identified) in red spruce needle wax increased (P<0·05) with increasing u.v.-B dose. Changes in wax chemical composition reported were induced following to daily, 4-h duration exposures of needles to u.v.-B centred on 1200 hours. Affected variables exhibited a continuum of response. The highest dose applied was within the range of measured or predicted increases in mid-northern latitudes. Such changes in conifer needle epicuticular wax chemical composition might result in increased seedling sensitivity to the changing atmospheric environment, especially from co-exposure to tropospheric ozone in mid-northern latitudes where much of Canada's productive forest is located.

A steel building at a cement plant un Utah was originally supported by spread footings. Shallow wetting of the coarse granular soils supporting the footings resulted in over three inches of settlement. Piles were used to underpin the building. The northeast corner column was supported by two 12 × 54 WF piles driven to depth 98 feet. About two years after the underpinning a deep wetting of the soils at the northeast corner occurred. The result was several inches of additional settlement on this corner of the building and twelve inches of ground subsidence adjacent to it. Excavation around the pile cap revealed that one of the piles was eight inches below the pile cap. A pull out test performed on the failed pile indicated the skin friction force was at least 182 tons. The building corner was underpinned again with three BP 12 × 74 piles driven to depth 145 feet. The upper 50 feet of each new pile was sleeved with an outer casing. Performance has been satisfactory since.

This paper proposes a novel carrier-based implementation strategy of a standard space-vector pulse-width modulation (SVPWM) technique of three-phase (3ϕ) three-level inverter (TLI). To synthesize the reference voltage vector, the selected SVPWM technique uses nearest three voltage space-vectors in order to reduce output voltage THD and partially balance the neutral point voltage. The implementation complexity of this SVPWM technique is reduced by introducing the concept of common-mode signal in duty-ratio calculation of 3ϕ-TLI. Following the modulation strategy of the selected SVPWM technique, general expression of common-mode signal has been derived in terms of maximum, middle and minimum values of input 3ϕ modulation signals. It is shown in the paper that six duty ratios of 3ϕ-TLI can be directly calculated from the input 3ϕ modulation signals and the derived common-mode signal. Thus, calculation-intensive steps of SVPWM technique, like, identification of reference voltage vector location, calculation of dwell-times of individual vectors, are avoided. The proposed algorithm is validated through simulation in MATLAB and experiment on 1.5 kW hardware prototype.


A brazed heat exchanger, having a block consisting of flat tubes and fins, having header tubes arranged at opposite ends of the flat tubes and having an additional tube, which is connected to one of the header tubes. To reduce brazing defects, provision is made for at least a significant part of an outer surface of the additional tube and/or of the header tubes to be of enlarged design.


A laterally gated Al/SiO2/SiC structure composed of an inner circular tunnel diode (TD) and an outer annular TD is investigated in this work to demonstrate the improved ultraviolet (UV) response in comparison with a single metal–oxide–semiconductor (MOS) TD or a conventional photodiode scheme. The current of the inner TD (ID) can interrelate with the bias of the outer TD (VG) against the voltage of inner TD (VD). This coupling effect will increase if the outer TD is negatively biased, thereby augmenting the optical current ratio and the responsivity. The lateral flow of holes is determined by the variation of the intermediate hole barrier between the inner and outer TDs. Once the hole potential at the outer TD overtops that at the inner TD, photogenerated holes from the outer TD can flow to the inner TD. Moreover, the suggested coupled TD design exhibits distinct increments in photocurrent under various illumination levels because of the coupling effect. For VD = −1.5 V and VG = −2 V, the optical current ...


We use QCD sum rules, in the framework of the Heavy Quark Effective Theory, to calculate the universal form factor $\tau_{1/2}(y)$ parameterizing the semileptonic transitions $B \to D_0 \ell \bar \nu$, $B \to D_1^* \ell \bar \nu$, where $D_0$ and $D^*_1$ are the members of the excited charmed doublet with $J^P=(0^+_{1/2},1^+_{1/2})$. We include two-loop corrections in the perturbative contribution to the sum rule, and present a complete next-to-leading order result. As a preliminary part of our analysis we also compute, up to order $\alpha_s$, the leptonic constant $F^+$ of the doublet $D_0$, $D_1^*$. Finally, we discuss the phenomenological implications of this calculation.

This article presents a resonant frequency tuning (RFT) delta–sigma (<inline-formula><tex-math notation="LaTeX">$\Delta$</tex-math></inline-formula>–<inline-formula><tex-math notation="LaTeX">$\Sigma$</tex-math></inline-formula>) signal-transformed pulse density modulation (PDM) class-D converter for inductive power transfer (IPT) applications. The proposed power controller provides a load-adaptive pulse modulation by tuning a zero phase angle and peak-power frequency, i.e., resonant frequency in the primary-side high-frequency inverter. The switching frequency is regulated in accordance with the variations of the load and coupling coefficient between the transmitting (Tx) and receiving (Rx) coils. The output power is controlled by the RFT-<inline-formula><tex-math notation="LaTeX">$\Delta$</tex-math></inline-formula><inline-formula><tex-math notation="LaTeX">$\Sigma$</tex-math></inline-formula> PDM, which is effective for reducing a low-frequency oscillation (subharmonics); thereby, the high-efficiency power transmission can be attained. The essential performances of the proposed IPT power controller are demonstrated in an experiment of a 400 W–500 kHz of prototype, whereby the feasibility is clarified from a practical point of view.


A collaborative National Science Foundation Research Experience for Teacher program involving three regional universities in the Midwest recently hosted its final cohort of teachers, preservice teachers and engineering students. This collaborative RET site placed the participant teams at one of the three regional universities to work on engineering research projects that connect with regional strengths in advanced manufacturing and materials. This paper will discuss the lessons learned from managing and facilitating a collaborative program. It will also discuss how this program was able to leverage regional assets to provide a deep and meaningful experiential learning opportunity for the participants. Finally, it will discuss how the participants were guided through a process to develop curriculum that connected their experiences and employed research based best practices for encouraging underrepresented populations to pursue engineering. INTRODUCTION Global competitiveness in future manufacturing will depend upon the maturation and adoption of advanced manufacturing technologies. These technologies include robotics [1], artificial intelligence [2], 3D printing [3-6], and nanotechnology [7, 8] that will offer much more cost-effective alternatives to so-called cheap labor costs offered by various countries. To complement this new era of manufacturing, engineers and scientists are to develop new types of materials that are compatible with the manufacturing technique, yet they are stronger, lighter, more energy-efficient, and more durable than existing manufactured goods. Thus, future global manufacturing will require more scientists and engineers in the field which is achievable if middle school and high school students are inspired and motivated to pursue college careers in related STEM disciplines. Our goal is to provide G6-12 teachers with training and tools such as curricular modules to use to inspire their respective classes in advanced materials and manufacturing. To achieve this overarching goal, three regional universities received a three-year NSF-Research Experience for Teachers (RET) in engineering grant titled "Inspiring the Next Generation of a Highly-Skilled Workforce in Advanced Manufacturing and Materials." The advanced manufacturing and materials focus was selected based on the regional needs and strengths in addition to the fact that all three participating universities have strengths in this area. The overall goals of this program were to: 1. Transfer the program's team-based applied engineering research activities into the teacher participants' classrooms through experience and the development and dissemination of new curriculum associated with these activities; 2. Provide the teacher participants with new knowledge of engineering disciplines and careers, particularly those related to advanced manufacturing and materials and generate a new appreciation for the value of diverse team-based learning environments; and 3. Provide the participants with beneficial professional development activities integrated into the RET programming. During the three year program, a total of 36 in-service and pre-service teachers were involved in hands-on research in advanced materials and manufacturing, curricular training, and a series of professional development activities. Each year most of the activities except for the onsite group research were performed collectively as an entire cohort. This paper presents a brief overview of the collaborative yearly activities designed for the RET teachers. Lessons learned are summarized. PROGRAM OBJECTIVES The collaborative program consisted of nine objectives to achieve the three broad goals as given in Introduction section. A. Teach engineering concepts to over 1,000 PK-12 students over the project period, including students from schools with a significant minority population (Goal 1). B. Develop inquiryand team-based STEM curriculum and innovative pedagogy to encourage interest in STEM and, in particular, engineering (Goal 1). C. Disseminate curriculum deliverables through the Teach Engineering digital library, and professional development workshops such as the STEM Think Tank (Goal 1). D. Have their STEM interest sparked by using modern engineering tools and gaining new knowledge of engineering careers (Goal 2). E. Understand the social relevance and ethical implications of engineering activities related to manufacturing (human rights, environmental impact, etc.) (Goal 2). F. Share knowledge, ideas and concepts working on teams with professional and preservice teachers, research mentors and industry partners (Goal 2). G. Acquire collaboration and networking possibilities through interaction with real-world engineering industry and government mentors and partners (Goal 3). H. Attain leadership roles in K-12 setting through the RET program's professional development component (Goal 3). I. Achieve long-term collaborative partnerships with the regional university research community and engineering professionals during substantial follow-up activities (Goal 3). COLLABORATIVE ACTIVITIES Most of the nine program objectives were carried out through a set of collaborative professional development and curricular activities that took place as an entire cohort. PI, co-PIs, and senior personnel from three universities participated in collaborative activities. The collaborative activities are discussed next. Recruitment and Participant Selection The recruitment effort included sending emails to school districts and posting announcements in the RET website [9] that appeared to be very effective in recruiting teachers from schools serving underrepresented populations. In three project years, a total of 36 in-service teachers were selected from approximately 75 applicants from different schools including urban, rural and suburban public, private and charter schools and one career technology center. In year 1, participants represented twelve different rural, urban and suburban Grade 5-12 schools. These schools have a percentage of students on free/reduced lunch that ranges from 4.3% to 100% and a non-white population that ranges from less than 1% to greater than 95%. [10]. More targeted recruiting was done for the years 2 and 3 cohorts to increase the impact to minority serving schools. In year 2, the majority of schools participating in cohort 2 had 14% or fewer nonwhites and less than 40% considered to be from economically disadvantaged districts [11]. In year 3, participants represented Grade K-12 schools, the majority of which had over 50% non-whites and over 80% economically disadvantaged. ASM Materials Camp Each year, the entire cohort of RET participants joined other teachers in the area to participate in the ASM Materials Camp. One of the participating universities hosted the ASM materials camp [12] during the first two years. In the third year, the camp was held in a local High School. During this one-week workshop, participants learned the basics of Materials Science and Technology (MST). They worked hands-on with metals, ceramics, polymers and composites, and developed a greater appreciation for the importance of these materials in modern life. This experience helped the RET teachers engage more quickly and fully with their research projects that happened in the weeks following this weeklong experience. Participants were provided with curricular tools; supplies needed to replicate some of the classroom activities and a one-year membership in ASM. Curriculum Development Activities Each year, the entire cohort of RET participants worked in small teams to develop curriculum under the guidance of a curriculum coach. In year 1 (2015), the curriculum development was facilitated by the City Regional STEM Center (DRSC). For the remaining cohorts, a teacher with expertise in curriculum development was added to the project team to serve as the curriculum coach for the RET participants. Additionally, a key addition for the 2016 and 2017 cohorts was a structured curriculum ideation session to help generate robust and highly innovative ideas for their lessons. These modifications to the curriculum development process resulted in lessons that were developed using the TeachEngineering Format. A total of 15 STEM curricular units were developed in three years. Year 1 and 2 units (10) are already piloted and the remaining five year 3 curricula are currently being piloted. Two curricula are published in TeachEngineering website [13, 14] and one is currently being edited/modified for publication on the same site [15]. Examples of curricular units developed include: Doghouse Design (Grades 4-5), Can You Hear Me Now? (Grade 8-10), Out-of-the Box: A Furniture Design + Engineering Challenge (Grade 8-10), Cell Phone Packaging Design (Grade 8-10), etc. Professional Development Activities Industry and University Tours: The cohort toured three campuses as well as local and state additive manufacturing (AM) and advanced manufacturing industries. These tours helped them become acquainted with the regional AM facilities so that they could talk about it to their students and inspire them to pursue college education in STEM. Research Seminars: Engineers and scientists from the participating region universities, industries, Wright-Patterson AFB, and other organization were invited to give informational and motivational speeches to the entire cohorts. Seminars were given on the day when the entire cohort was gathered for curriculum development. It was ensured that the content of each lecture was appropriate for teachers. Supplementary presentations: The RET participants were given additional informative presentations on various topics as needed. For example, they participated in training sessions given by a librarian on how to perform a literature review on a given topic. The RET participants presented their developed curricula and research work at a day-long symposium at the end of the RET. This helped them


Traditionally, metaphors were perceived as a mere ornamental device used by poets to embellish their language. With the advent of cognitive linguistics, the perception of metaphor has been "revolutionized." Metaphor has ceased to be considered as a purely linguistic device. It is studied as a cognitive instrument, shaping our language, thought and action (Lakoff & Johnson, 1980; Kὅvecses, 2002). Metaphors are found to be very pervasive in everyday language. They are used by native speakers to express abstract concepts such as emotions and time. This paper aims at filling this gap, at least partially, by providing a cross-linguistic analysis of happiness metaphors in these three unrelated languages. The Conceptual Metaphor Theory (the CMT), as proposed by Lakoff and Johnson (1980), is adopted in this study as the analytical framework. Thus the methodological tools provided by the CMT, such as "conceptual metaphors", "linguistic metaphors", and "cognitive transfer" are used for the analysis of the data at hand. The results suggest that English, Tunisian Arabic and Spanish share many conceptual metaphors for happiness, such as HAPPINESS IS A FLUID IN A CONTAINER, HAPPINESS IS LIGHT, HAPPINESS IS BEING OFF THE GROUND. Some differences are observed at the conceptual and linguistic levels, which can be attributed to cultural differences.


Imagine that you are a teenager and have cancer. You undergo a year of chemotherapy and after a brief return to normal life, you have a relapse. Your physician says that chemotherapy and radiation therapy could be tried, but a bone marrow transplant (BMT) is your only chance of a real cure. He tells you and your parents that you could die as a result of complications from the transplant, but without it you would only be expected to live one year. You and your family discuss the alternatives and decide to have the transplant. You ask what will happen if the BMT fails, but both your physician and your family tell you that right now you must fight to get better and not think negative thoughts. You do not ask any more questions.


Context: The incidence and mortality of thrombotic disorders are rapidly increasing throughout the world. Therefore, attempts have been made to develop new anticoagulant and antithrombotic drugs. Our previous studies showed that a novel protein, named Fu-P, had fibrinogenolytic activity and much higher fibrinolytic activity on the fibrin plate than urokinase in vitro. Objective: The antithrombotic activities of Fu-P in vivo are investigated here for the first time. Materials and methods: Antithrombotic activity of Fu-P was studied in a rat model of artery-vein bypass thrombosis. The anticoagulant activity of Fu-P was measured by clotting assay of activated partial thrombinplastin time and prothrombin time (PT). The effects of Fu-P on the factor Xa and thrombin were assayed using the chromogenic substrate S-2765 and S-2238. Results: Intravenous injection of Fu-P produced a 58.4% inhibition ratio of thrombus formation at 0.1 mg/kg body weight, while heparin produced 42.5% inhibition ratio of thrombus formation at 0.6 mg/kg body weight. Fu-P significantly prolonged fibrinogen clotting time, activated partial thrombinplastin time and thrombin time, which also prolonged PT. The inhibition assay of the coagulant factors using chromogenic substrates S-2238 and S-2765 showed that Fu-P was not the inhibitor of the thrombin and Xa. Discussion and conclusion: These findings demonstrated that the novel fibrinolytic enzyme (Fu-P) might also be used as a natural agent for thrombolytic therapy or thrombosis prevention.


OBJECTIVES
This study evaluated buccal bone crest remodeling, socket composition after healing, and dimensional ridge preservation after flapless tooth extraction procedures with or without a xenograft comparing histomorphometric and microcomputed tomographic (micro-CT) data.

MATERIAL AND METHODS
The mandibular premolars of eight dogs were extracted without flaps. One socket on each side received a grafting material (test group), and the other remained only with a blood clot (control group). Twelve weeks after treatment, buccal bone crest, alveolar ridge dimensions, and composition were analyzed by histomorphometry and micro-CT.

RESULTS
Two- and three-dimensional evaluations showed better results for the grafted group when compared to the non-grafted group.

CONCLUSION
The flapless alveolar ridge preservation procedure with deproteinized bovine bone material enhanced buccal bone crest, alveolar ridge dimensions and bone formation when compared to sockets with the blood clot only, as observed by histomorphometric and micro-CT analysis.

The object of research was the first-calf cows of Black-and-White breed. The groups were formed taking into account the part of blood of Holstein breed. The 1st group included animals with the part of blood than 50 % (an average of 37 % in the group), the 2nd with the part of blood of 50 % and the 3rd more than 50 % (an average of 63 % in the group). An increase in the part of blood in animals in the farm to 63 % had a positive effect on changing the shape of the udder. Thus, in the group of low the part of blood animals there were 78,2 % of cows with a cup-shaped shape and 21,8 % with a rounded one. Among half-blood cows with the cup-shaped udder accounted for 92,2 %, and with the rounded one it was 7,8 %, among the high part of blood it was 94,8 and 5,2 %%, respectively. In terms of udder length and depth measurements, cows with the high part of blood outperformed cows with the low part of blood by 2,5 cm (р < 0,01) and 2,1 cm (р < 0,01), respectively. In terms of udder decline, the difference between these groups of animals was 5,7 abs.% (р < 0,01) in favor of animals with the higher proportion of Holstein breed blood. First-calf cows with half part of blood and the high part of blood of Holstein breed were ahead of their herd mates with the low part of blood in terms of the rate of milk speed out the difference was 0,3 kg/min (р < 0,05) and 0,4 kg/min (р < 0,001), respectively. The most common udder defect (10 %)was narrow rear teats, while in the group with the high part of blood cows its occurrence was the lowest 6,7 %. The sum of the frequencies of udder defects in cows with the high part of blood was 16,7 % versus 23,3 % in the other two groups. We recommend to use purebred Holstein sires for mating with low-blood heifers and cows, and using sires with the part of blood of Holstein breed of 62 to 75 % or breeding "inter se" on heifers and cows with the higher proportion of blood of Holstein breed.

The intermetallic thitkness and morphology change during aging were characterized using SEM, EDS and XRD. and were observed in the solder/pt interface and the intermetallic formation was governed by diffusion. The activation energy of intermetallic formation was 145.3 kJ/mol for specimens for specimens from the measurement of the intermetallic thickness with aging temperature and time.


With technological advancements and constant changes of Internet, cloud computing has been today's trend. With the lower cost and convenience of cloud computing services, users have increasingly put their Web resources and information in the cloud environment. The availability and reliability of the client systems will become increasingly important. Today cloud applications slightest interruption, the impact will be significant for users. It is an important issue that how to ensure reliability and stability of the cloud sites. Load balancing would be one good solution. This paper presents a framework for global server load balancing of the Web sites in a cloud with two-level load balancing model. The proposed framework is intended for adapting an open-source load-balancing system and the framework allows the network service provider to deploy a load balancer in different data centers dynamically while the customers need more load balancers for increasing the availability.


Using two‐step laser excitation it is shown that the state distributions of highly excited barium atoms are substantially altered by inelastic collisions with barium atoms. For ''pure'' Rydberg states the initially produced ns or nd eigenstates are rapidly mixed with nearly degenerate n'l' states. For initially produced states that may be viewed as admixtures of Rydberg and doubly excited independent electron eigenstates, collisions convert the distribution to one with nearly pure, albeit state‐mixed, Rydberg character. Broadening of the absorption profiles of the highly excited states is also observed.

We evolved from herbivores to a meat eating "commons" in hunter-gatherer days and then to a non-egalitarian meat power struggle between classes and countries. Egalitarian-ism, trans-egalitarianism and extremes of inequality and hierarchy revolve around the fair-unfair distribution of meat surpluses and ownership of the means of meat production. Poor people on poor diets with too few micronutrients may explain many inequalities of human capital, height and health and divergent development of individuals and nations. Learning from past successes and collapses from switching trophic levels the lesson is that meat moderation toward the top of Engel's curves, not calorie-centrism, is the best recipe for countries and classes. Improved health with longer lives and higher crystallised intelligence comes with an ample supply of micronutrients from animal products namely iron, zinc, vitamin A, vitamin B12 and other methyl-donors (such as choline), and nicotinamide (vitamin B3). We concentrate on nicotinamide whose deficits cause the degenerative condition pellagra that manifests as poor emotional and degenerative cognitive states with stunted lives and complex antisocial and dysbiotic effects caused by and causing poverty.


The Agiasmati cave in SW Crete, investigated as part of the Sphakia Survey, served as a sanctuary in the Hellenistic-Early Roman period. It has four points of interest, (1) Two of its principal types of artefacts, ladles and multiple-nozzle lamps are rare or even unique to this site. (2) Fabric analysis has enabled significant progress to be made with the interpretation of the pottery. (3) Cave worship in this period is not well known on Crete. (4) Intensive exploration by the Sphakia Survey of the region in which the cave lies enables us to place the cave in the context of the contemporary settlement pattern and to reconfirm the value of archaeological survey.


In this paper, we report the room-temperature ferromagnetism (FM) of a pure SnO 2 nanostructure with various morphologies synthesized by a chemical vapor deposition (CVD) method and study the growth condition dependences of morphology and magnetic property. As the growth temperature is increased from 700 to 900°C, the average diameter of Sn0 2 nanowires (NW) increases from 20 to 60 nm, while magnetization decreases from 0.223 to 0.081 emu/g. However, morphology and FM are not sensitive to the argon flow rate during the CVD synthesis. Selected area electron diffraction, X-ray diffraction, and X-ray photoelectron spectroscopy measurements show that all the samples possess a typical rutile structure, and no other impurity phases are observed. The results demonstrate that the ferromagnetic properties of the samples are related to the morphology and exhibit an increment trend with the increasing surface-to-volume ratio. With a combined study of photoluminescence, our results reveal that the oxygen vacancies mainly at the surface of NW contribute to the FM of SnO 2 nanostructures.

Classical plasma with arbitrary degree of degeneration of electronic gas is considered. In plasma N (N>2) collinear electromagnatic waves are propagated. It is required to find the response of plasma to these waves. Distribution function in square-law approximation on quantities of two small parameters from Vlasov equation is received. The formula for electric current calculation is deduced. It is demonstrated that the nonlinearity account leads to occurrence of the longitudinal electric current directed along a wave vector. This longitudinal current is orthogonal to the known transversal current received at the linear analysis. The case of small values of wave number is considered.


Plasma scientists have rushed to take advantage of a new $13 million federal program aimed at generating more basic knowledge about these ionized gases. Jointly sponsored by the Department of Energy and the National Science Foundation, the program aims to reverse a decades-long pattern of viewing plasma science as a large collection of applications, from fusion energy to plasma processing of semiconductors, and revitalize its scientific underpinnings.


The six-, eight- and twelve-membered cyclo-siloxanes, cyclo-[R2SiOSi(Ot-Bu)2O]2 (R = Me (1), Ph (2)), cyclo-(t-BuO)2Si(OSiR2)2O (R = Me (3), Ph (4)), cyclo-R2Si[OSi(Ot-Bu)2]2O (R = Me (5), Ph (6)) and cyclo-[(t-BuO)2Si(OSiMe2)2O]2 (3a) were synthesized in high yields by the reaction of (t-BuO)2Si(OH)2 and [(t-BuO)2SiOH]2O with R2SiCl2 and (R2SiCl)2O (R = Me, Ph). Compounds 1—6 were characterized by solution and solid-state 29Si NMR spectroscopy, electrospray mass spectrometry and osmometric molecular weight determination. The molecular structure of 4 has been determined by single crystal X-ray diffraction and features a six-membered cyclo-siloxane ring that is essentially planar. The reduction of 1—6 with i-Bu2AlH (DIBAL-H) led to the formation of the metastable aluminosiloxane (t-BuO)2Si(OAli-Bu2)2 (7) along with Me2SiH2 and Ph2SiH2.

Die Verbindungen 1—6 wurden durch Losungs- und Festkorper- 29Si- Kernresonanzspektroskopie, Elektrospraymassenspektrometrie und mittels osmometrischer Molekulargewichtsbestimmung charakterisiert. Die Molekulstruktur von 4 wurde durch Rontgenbeugung am Einkristall bestimmt und beschreibt einen nahezu ebenen sechsgliedrigen cyclo-Siloxanring. Die Reduktion von 1—6 mit i-Bu2AlH (DIBAL-H) fuhrte zur Bildung des metastabilen Aluminosiloxans (t-BuO)2Si(OAli-Bu2)2 (7) und Me2SiH2 bzw. Ph2SiH2.


The Wellbeing Economy is an emerging paradigm with useful assumptions for framing economic, environmental, social and political goals. Finding the route to reaching these goals is part of what advocates are seriously concerned about. They are mainly concerned about how to improve the wellbeing of people and ecosystems. This certainly did not make much sense to me prior to November 2015. The director of the Centre for the Study of Governance Innovation at University of Pretoria, South Africa, Professor Lorenzo Fioramonti, had invited me to participate in an initial meeting of would-be members of the Wellbeing Economy Africa Network (WE-Africa Network, for short). It was illuminating. Between that time and November 2017, Lorenzo, convener of the wellbeing economy conferences and main driver of the dream of a wellbeing economy movement in Africa, launched a new book, Wellbeing Economy, Success in a World without Growth. 1 Apart from the intellectual engagement with issues of conceptualization and indicative arguments about what the concept means, this book echoes a tacit call for theory and praxis, in the aspirations for change across Africa. The political economy background of the book presents good reading of the African situation. The quick message was, as now, an arrival of a paradigm, which is not necessarily new in postcolonial engagement with development discourses and critique of global capitalism. The wellbeing economy framework is intended to guide development thinking and action. It is about desire for change in the way countries organize their economies, away from the growth mantra. Clearly, the framework is a pointer to an effort by advocates seeking a paradigmatic shift, strong enough to serve as conceptual and analytical tool for activism and change. Within the period, at the instance of Lorenzo's leadership, a Wellbeing Economy Lab was created, with innovation as a key goal. This has

Through the exchange of nonverbal and verbal behaviors, a man and a woman on a date negotiate situated identities. However, a woman's nonverbal and verbal behaviors may reflect an identity discrepant from the one she intended to project, leading to miscommunication between men and women regarding the woman's desire for sexual activity. In Experiment 1, subjects read scenarios in which a woman, Mary, engaged in behaviors that were low, moderate, or high in the degree to which they connotated a desire for sex. In addition, they learned that Mary responded to her date's sexual advances either by saying "no," or by slapping him, or they received no information regarding Mary's verbal response. Subjects were also informed that Mary's date either did or did not force her to have sexual intercourse. Subjects perceived Mary more sexually as her behaviors increased in sexual connotation. In addition, they perceived that Mary desired sex more when no information about her verbal response was provided than when she ...


The development of new functional foods is an opportunity to improve the quality of food offered to consumers in order to positively affect their health. Food products with added value are subjected to increasing industrial and social interest in the contemporary society. The selection of strains of lactobacilli, bifidobacteria and propionic acid bacteria and yeasts for the development of starters for a wide range of food products dairy, meat, cereals, etc. is especially prospective for production and development of functional foods. Thus the currently used preservatives in food production can be reduced or replaced. According to FuFoSE, in a coordination with ILSI, Europe a food product can be considered functional if together with its basic nutritional effects it has beneficial effects on one or more functions of the human body, thereby improving the overall and the physiological condition, or reducing the risk of developing a disease. Lactic acid bacteria play a key role in food fermentations, contributing to the development of desired organoleptic properties of the final product and the microbiological safety [3, 8]. For many years, chocolate was consumed entirely for pleasure, but in the last 20 years, several studies have shown that dark chocolate and cocoa may have beneficial effects on human health due to the high content of polyphenols. Many studies have shown that polyphenols and/or polyphenol-rich foods play an important role for the health of the consumer due to their antioxidant properties [2, 4, 6]. These properties allow them to act as anticarcinogenic, anti-inflammatory, antihepatotoxic, antibacterial, antiviral and antiallergic compounds [1, 7, 9]. In addition to reducing blood pressure levels, cocoa polyphenols probably influence the control of cholesterol. Chocolate and cocoa contain not only polyphenols but also methylxanthines, which could further contribute to the impact of these foods on health [5]. The purpose of the present study was to investigate the possibilities for applying probiotic Lactobacillus strains in the manufacture of milk chocolate.


The launch of the United Nations Decade of Education for Sustainable Development (UNDESD) gives the education community opportunity to reflect on and discuss major issues that will affect the future well-being of our world. Discussions should include questions such as, "What is my discipline's contribution to a more sustainable future?" and "What are the ties and linkages between my discipline and ESD?" In this article we look at the similarities between environmental education (EE) and education for sustainable development (ESD). We also describe some lessons learned from more than 35 years of EE history. These lessons could help ESD avoid pitfalls common to nascent disciplines and to advance its efforts and chance of success.


One of the greatest challenges for the modern world is the ever-increasing demand of energy, which may soon outstrip the amount of natural resources that can be obtained using currently known energy conversion and energy storage technologies such as solar cells, fuel cells, lithium ion batteries, and supercapacitors. It appears that the maximum output efficiencies of these devices have already reached the intrinsic limits of almost all electrocatalyst materials. Hence, it is a high time to think about new material architectures by controlling size, shape, and geometry, as well as composition that can potentially make a significant improvement in the performance of these electrochemical devices. Among several known electrocatalyst materials are nanomaterials and their composites due to their unique electrical, mechanical, physical, chemical, and structural characteristics. These materials have opened a whole new territory of possibilities in designing high performance energy storage and conversion devices. In this chapter, the authors review the recent progress in energy storage and conversion devices that utilize various nanomaterials and their composite materials and identify future directions in which the field is likely to develop.


The secondary instability with respect to the existing 2-D nonlinear coherent structures was studied by using of the theory of secondary instability.The results showed that the subharmonic instability was most unstable in the 2D limit,while for the fundamental instability,3-D wave with a certain spanwise wavenumber was most unstable.Comparison between the calculated spanwise wavelength for the most unstable wave and the observed one showed that the theoretical and experiental results agree each other reasonably well.


The double-bounded contingent valuation method (DBCVM) has long been criticized as an inappropriate estimation method because of respondents' inconsistent behavior during a course of DBCVM survey. Many experimental studies have reported that two subsequent answers are not made independently, but the second answer depends upon the first. There are many kinds of hypotheses, each of which contends a different pattern of dependence of the answers. In this study, it will be tested which hypothesis is more appropriate in explaining the dependence of the answers. For the test, the DBCVM under uncertainty is newly developed here in which some uncertainties associated with the CVM are recognized and the risk premium plays a criterion for respondents to answer.

Magnetic nanoparticles (MNP) enhanced microwave imaging could provide an effective approach for an early stage diagnosis of breast cancer, if encouraging results coming from accurate and realistic numerical studies are confirmed by an experimental proof of concept framework. To this end, an ad hoc laboratory setup has been designed and built up to verify the possibility of detecting the low signal scattered by MNP when embedded into a simplified but realistic breast phantom. This paper describes the developed measurement setup and the results coming from a first run of experiments, which confirm the possibility to detecting realistic amounts of accumulated nanoparticles. Moreover, the experimental results analysis allows addressing the future developments required to determine the ultimate detection limits of the technique, giving relevant information to plan the preclinical assessment.


Housekeeping is the smallest community of a society. Household a happy, safe, and secure into everyone's dream. Wholeness and harmony of a household can be impaired if the attitude, behavior, and self-control can not be controlled. Ultimately can occur domestic violence causing insecurity or injustice against people who are within the scope of the household. From the result of the violence, the victim should be restored to rise physical and psychological conditions. Inhibiting factors is a recovery of victims of domestic violence is that most of the victims do not want to restore condition, efforts to resolve it provides socialization, convincing victims of domestic violence to want to restore, to supervise the victims have been recovered. Supporting factors is the facility is being used in the recovery process is adequate, the victim does not charge at all during the recovery process. In conclusion, the service process and the recovery of victims of domestic violence conducted by the relevant institutions have been equally effective and in accordance with the legislation in force. Saran, We suggest to set up a special team to handle the implementation of the recovery of victims of domestic violence.


Along with the development of the electric power ind ustr y and the urban network construction, the XLPE cable has been broadly adapted in the distribution network, i n order to utilize it more excellent, and promote development of the distributio n network, the paper makes research and analysis about the verification of the X LPE cable, and indicates the theory basis of inadvisable applying the DC voltage -withstand method, as well as proposes the rationality of the low-frequency ver ification method and its developing prospect.


Seasonal variations of human body functions are well documented,l but it has been a matter of debate whether or not the human circadian rhythms are influenced by, for instance, seasonal changes in a day length or ambient temperature. In our previous study? human circadian rhythms were demonstrated to phase-shift in response to bright lights. The finding suggests that the seasonal variation in the day length might change the phase of human circadian rhythms. To examine this possibility, we measured circadian rhythms in sleep-wakefulness, rectal temperature and plasma melatonin level in four seasons.


The present article describes the experimental characterization of construction-technology parameters of 3D micro-contacts, implemented in IC package to PCB assembly and micro mechanical actuators. This paper presents experimental results of the horizontal elements investigation, relative to the 3D micro-contacts. Thermal simulations of the proposed structures are also included. This issue is of a great importance, due to the nature of the horizontal elements - actuator type and bending features. The test structures are made electro-chemically of two micro-junction elements: a pin over a chip-carrier and a ring over a substrate-carrier. The tight contact between the pin and the ring during the fitting of micro-junction structures is a guarantee for the electric contact and heat transfer. The thermal optimization of construction-technology parameters of the 3D micro-contacts from stud-ring type is achieved by use of CFD simulations. A 3D numerical model, based on computational fluid dynamics, was constructed to represent the whole package. For the sake of model simplicity, during the modeling procedure it was considered the components that have the most representative size and power dissipation.


It is appropriate that on pages 279-80 of Less than Nothing: Hegel and the Shadow of Dialectical Materialism Slavoj Žižek refers to Pierre Bayard's How to Talk about Books You Haven't Read. Appropriate because, by the time we get to page 280, there are still some 730 pages to go and it feels like Less than Nothing will be a book we will never read, or – the book is so long – by the time we get to the end we will not remember whether we have read it or not, or – such is the size of the book – it is not really a book that can be read or is even meant to be read. And let us not begin to make jokes about a book 1010 pages long being called Less than Nothing! (Indeed, in a first Hegelian touch – insofar as for Hegel it is always a matter of the "subject's position of enunciation having to be included" (553), and everything in the book, again as in Hegel, is a staging of itself – we wonder whether Žižek, given his previous famous admissions that he never saw the end of Spartacus before writing about it and did not see any of Avatar before writing about it, has actually read Bayard's book before putting it to such good use here.) And we might put all of this another way, which is to suggest that, such is its length, the fact that we will never get to the end of reading Less than Nothing is the strict correlate of the fact that, even from the beginning, we can only ever re-read it.


A novel design of an adaptive artificial neural network technique (ANN) for controlling of the essential parameters, like as speed, torque, flux, voltage, current, and power etc of the induction motor is presented in this paper. Induction motors are characterized by way of incredibly non-linear, complicated and time-various dynamics and inaccessibility of its states and outputs for measurements. Thus it can be considered as a challenging engineering difficulty in the industrial sector. A few of them, such as PI, fuzzy strategies, Fuzzy logic based controllers are regarded as capability candidates for such application for operating induction motor. Hence of which, the outcome of the controller is also random and high-rated results are probably not obtained. Resolution of the proper rule base application upon the drawback can be achieved by the use of an ANN controller, which becomes a built-in system of method for the manipulate purposes and yields results, which is the focus of this paper. Within the designed ANN scheme, neural community tactics are used to prefer an appropriate rule base, which is utilizing the back propagation algorithm. The simulation outcome provided on this paper is exhibit the effectiveness of the developed approach, which has acquired faster response time or settling times. Additionally, the procedure developed has got a huge number of benefits within the industrial sector will also be converted into a real time application making use of some interfacing cards.


Utilising archival Chandra X-ray Observatory data and Hubble Space Telescope globular cluster catalogues, we probe the time-domain properties of the low mass X-ray binary population in the elliptical galaxy NGC 4261. Of the 98 unique X-ray sources identified in this study, 62 sources are within the optical field of view and, of those, 33% are aligned with an optical cluster counterpart. We find twenty X-ray sources coincident with globular clusters; two are previously discovered ultra-luminous X-ray sources (ULXs) and eighteen are low mass X-ray binaries (GCLMXBs) with LX < 1039 erg s−1. ULXs are a heterogeneous class of extremely bright X-ray binaries (LX > 1039 erg s−1) and ULXs located in globular clusters (GCULXs) and may be indicators of black holes. Identifying these unusually X-ray bright sources and measuring their optical properties can provide valuable constraints on the progenitors of gravitational wave sources. We compare observations of these sources to the twenty previously-studied GCULXs from five other early-type galaxies, and find that GCULXs in NGC 4261 are of similar colour and luminosity and do not significantly deviate from the rest of the sample in terms of distance from the galaxy centre or X-ray luminosity. Both the GCULX and low mass X-ray binary (GCLMXB) populations of NGC 4261 show long term variability; the former may have implications for fast radio bursts originating in globular clusters and the latter will likely introduce additional scatter into the low mass end of GCLMXB X-ray luminosity functions.


Abstract Women bodybuilders exemplify gendered deviance and risk a social stigma on top of the physical risk of partaking in this demanding sport. In the current study, we utilize Stephen Lyng's (1990, 2005) theoretical concept of "edgework" to understand what motivates women bodybuilders to engage in this high-risk behavior. Our qualitative analysis of 29 women bodybuilders' responses to open-ended survey questions reveals that the three components of edgework (activity, skill, and sensation) are evident in their training and dietary regimens. Overall, this study offers an important theoretical contribution to the study of women's bodybuilding while also extending Lyng's edgework model to this understudied phenomenon.


Objective To analyze molecular biology characteristics of measles virus isolated and master the genetic characteristics of measles epidemic strains in Jiangxi Province. Methods Measles virus was isolated from throat swabs of suspected measles patients from 2008 to 2012 using Vero/SLAM cells. RT-PCR method was employed to amplify N gene fragment of measles isolates for sequencing. Then the homogeneity of the sequence between these measles virus and the representative strains with each genotype in Gen Bank were analyzed. Results All measles virus isolated in Jiangxi Province from 2008 to 2012 belonged to genotype H1, which had been a main genotype in China. The isolates shared 98.1%-100% identity of amino acid sequence on N gen. When compared to the virus of H1 genotype strain(China93-7), there were 97.5%-98.7% homogeneties on N gene. Compared to the China vaccine strain(Shanghai 191), there were 95.0%-96.2% homogeneties on N gene. Conclusion Data from phylogenic trees of N gene revealed that the wide-type measles viruses isolated in Jiangxi Province in 2008-2012 both belonged to genotype H1.


Non-dipping of blood pressure refers to the absence of at least a 10% reduction in average nighttime (asleep) ambulatory blood pressure (ABP) when compared to average daytime (awake) ABP (1–4). Non-dipping may predict increased cardiovascular risk (1), and identifying correlates of non-dipping has been the topic of a number of studies (2,5–7). Indeed, in common in black non-Hispanic low perceived racism in a sample of 180 community-dwelling Hispanic participants. This paper an ABP (ABPM) device for measuring non-dipping, we were by the "Only one had to the ABP due to initial poor-quality Otherwise, there no protocol technical failures, or insufficient number of ABP readings 842)"


Background: In the last decades, there has been an escalating consumption of antibiotics with the number of antibiotic prescriptions increasing worldwide. Since children are more vulnerable to infectious disease than adults, more antibiotics are prescribed for them. Inappropriate use of antibiotics has resulted in a major increase in the development of multi-drug resistant pathogens with great implication in terms of morbidity, mortality and costs. The objective of this study was to determine the irrational use of antibiotics prescribed for children under the age of 15 years in Mekelle general hospital. Methods: A retrospective cross sectional study was conducted. Four hundred three children's prescriptions and corresponding cards which were recorded by the year 2012 were selected by systematic random sampling proportionally from each month in the year. Results: Of all antibiotic prescriptions reviewed, the numbers of outpatient antibiotic prescriptions were 222 (55.1%) while inpatient prescriptions were 181 (44.9%).The predefined antibiotics indicators like percentage of antibiotics prescribed, frequency of route of administration, antibiotics prescribed from Standard treatment guideline, proportion of antibiotics, cost of antibiotics per antibiotics days, incidence and antibiotics utilization ratio were determined and 141(35.1%) were treated with different antibiotics irrationally. Conclusion: The finding of this study indicated that antibiotics were prescribed irrationally. Prescriptions containing one or more antibiotics constituted 73.68% of all prescriptions and around 5.9% of encounters were treated without any diagnosis.

The invention discloses a configuration and application method of a semicontinuous scheduling resource. The method comprises the following steps: when a user accesses, a base station distributes a semicontinuous scheduling resource for the user based on the principle that the nearest idle semicontinuous scheduling resource block at present is allocated preferentially to the user; and for an idle semicontinuous scheduling subframe, the semicontinuous scheduling resource can be used in a scheduling mode. By adopting method in the invention, the utilization of the semicontinuous scheduling resource can be effectively improved.


: The present study aims to innovate small hybrid desalination plants suitable for remote regions working with higher productivity and lower cost of the produced fresh water. To achieve this idea, the small RO desalination plant was combined with the solar still, as well as this innovative hybrid desalination system was combined with the photovoltaic/thermal panel and the evacuated tube solar collector as preheating units to heat the water before it entered the proposed innovative small hybrid desalination plant. To illustrate the characterized of the proposed innovative small hybrid desalination plant, the performance of an innovative small hybrid desalination plant was compared to the conventional small RO desalination plant experimentally under the climate conditions of Tanta city, Egypt. The results presented that the annual permeate water that can be produced from the conventional small RO desalination plant without modification reached 173.74 m3/year, but for the proposed innovative small hybrid desalination plant the annual permeate water that can be produced will be increased to 352.59 m3/year, with an improvement of 102.94%. Also, the economic analysis presented that the cost of permeate water produced from the conventional RO plant without modification reached 0.915 $/m3. But the permeate water cost produced from an innovative small hybrid desalination plant will be reduced to 0.8178 $/m3, saving 10.62%.


Summary form only given.Thin films of ordered organic semiconductors are being investigated as channel materials in field-effect transistors for a variety of applications. A detailed understanding of charge transport in such organic thin- film semiconductors used in field-effect transistors is of fundamental interest and is also essential to improve device performance. Our work examines the dynamic response of organic transistors in detail and extracts the drift velocity and mobility directly. The drift mobility and field-effect mobility are compared for pentacene and a liquid crystalline polymer with high mobility. The switching speed of FETs with channel length in the 2-8 micron range and scaling behavior of organic transistors (with channel lengths from 10 nm to 5 microns) are described. Frequency domain measurements have been made on diode connected transistors. Comparisons between frequency domain and time domain measurements will be presented. Finally, two important applications of organic transistors: RFID Tags and display drivers are discussed with regard to speed/mobility requirements and future trends.


From contents, methods, links and soft environment of teaching this paper analyzes problems currently existing in the teaching programming in C++, and then presents a new teaching idea which primarily aims to cultivate programming ability for students. The idea, which organizes contents of teaching from learning the use of C++ language, developing simple programs to developing programs for solving difficult problems, hence to developing software on some large scale, will combine corresponding computer knowledge and guide students to construct a self-contained software knowledge system. According to properties of contents, different teaching methods will be flexibly used to optimize overall teaching results. After the course is completed, research-based course design will be set for students to efficiently promote their transitions from mastering the use of C++ language to applying it to solve realistic problems.


A graph labeling is an assignment of integers to the vertices or edges or both subject to some conditions. The concept of cordial labeling was introduced by Ibrahim Cahit in 1987 as a weaker version of graceful and harmonious labeling. A product cordial labeling of a graph 𝐺 = (𝑉(𝐺), 𝐸(𝐺)) is a function 𝑓: 𝑉(𝐺) → {0,1} with each edge 𝑢𝑣 assign label 𝑓(𝑢)𝑓(𝑣) , such that the number of vertices with label 0 and the number of vertices with label 1 differ at most by 1, and the number of edges with label 0 and the number of edges with label 1 differ by at most 1. In this paper we investigate product cordial labeling of the graphs obtained by duplication of some graph elements in crown, helm and wheel graph.


The paper presents two solutions for the design of a 45/spl deg/-incidence S/X/Ka-band dichroic mirror for a European Space Agency ground station supporting deep space missions. The dichroic mirror is required to reflect completely in S band (2.025-2.3 GHz) and X band (7.145-8.5 GHz) and to be transparent in Ka band (31.8-34.7 GHz). The first mirror, consisting of a thick metal screen perforated periodically with rounded rectangular holes, has been fabricated and measured. A second design, based on a metal screen with hexagonal holes, has also been investigated, and it has been proved that this solution provides better overall antenna performance.


This article summarises the information that is currently available on the manuscripts of the medieval Castillian translation of the book, Vida de Crist, by Francesc Eiximenis. Following that, the author describes the manuscript at the Escorial Library, h. 111.22, and the manuscripts 780 and 12688 at the Madrid National Library, which contain texts from Eiximenis' translation, interpolated in the Medieval Spanish translation of the book Flos Sanctorum. These interpolations like the other manuscripts, almost all of them fragmented, of Eiximienis' medieval Castillian translation, along with the translations of the book Llibre dels Angels and Llibre de les Dones, show the interest in Castille for the work of the menoret (Friar Minor) from Girona, a topic which has only just started to be studied.


In late modernity masculinity and gender differences might be seen as commodities in the labour market. This article discusses from a poststructural perspective different concepts of masculinity and gender equality among men working as pre-school teachers and hairdressers in Sweden. The men both reproduce and renegotiate gender relations. The same man uses different, sometimes arbitrary, discourses. Stereotypes linked to the occupations and the male body are actualizing the heterosexual matrix in the workplace. Two strategies are found. Some men do not stress gender as a categorization and emphasize similarities between men and women while other men actualize gender difference.


Presentation of Case A 70-year-old woman was admitted to the hospital because of back pain and diarrhea. At least 30 years earlier she began to experience Raynaud's phenomenon that affected the fingers and later the feet. Twenty-six years before admission bilateral dorsal sympathectomy was performed, with only transient benefit. Twenty years before entry there was the onset of intermittent abdominal cramps and diarrhea. For many years she experienced postprandial distention without pain, often accompanied by nausea. Ten years before admission there was an attack of severe abdominal pain, with syncope and diarrhea, that persisted for three days; a barium-enema examination . . .

The local structural properties of representative amorphous oxides, ZnO, HfO2, ZrO2, and In2Ga2ZnO7 were investigated by using X-ray absorption spectroscopy and an ab-initio theoretical calculation (FEFF). The X-ray absorption near-edge structures of the amorphous systems were compared with those of their crystalline counterparts, and were interpreted in terms of weakened structural orders (in the case of ZnO, HfO2, and In2Ga2ZnO7) or fundamentally different local structures (ZrO2; monoclinic-like local structure favoured in amorphous phase in contrast to the tetragonal structure in crystalline film).


Abstract The experiences of researchers, historians, and other scholars of cryptologic records have, for a long time, been aware that confines of historic cryptologic material do not lie at the borders of Record groups 457 and 38. Yet, to know what other record groups to peruse, one needs to understand the bureaucratic structures within which the cryptologic organizations reside. Similarly, researchers need to consider record groups of organizations outside the collections of cryptologic records which had relations with cryptologic elements, either as production partners or consumers of communications intelligence.


The half-filled two-dimensional Hubbard model in presence of a uniform and static parallel magnetic field has been studied by means of the Composite Operator Method. A fully self-consistent solution, fulfilling all the constrains coming from the Pauli principle, has been found. The relevant features of a metal-insulator transition in presence of a magnetic field have been analyzed. The results qualitatively agree with the ones recently obtained by means of experimental investigations.


This study describes how the scientific and technical literature can be used as a source of data to analyze the emergence of new fields. In particular, the literature is used to determine the length ofcontribution spans ofindividual researchers in afield Through the use ofstatistical technicjues, such as survival analysis, the authors examine the probability that a researcher will contribute to the fieldfor a specified length oftime and the probability that a researcher, having contributed to the field for a specified period of time, will cease to contribute in the future. The authors aLo test the significance of several variables in explaining researchers' contribution spans.

This paper
considers the asymptotic dynamics of steady states to the Lotka-Volterra
competition diffusion systems with random perturbations by two-parameter white
noise on the whole real line. By the fundamental solution of heat equation, we
get the asymptotic fluctuating behaviors near the stable states respectively.
That is, near the steady state (u,v)=(0,1), the mean value Eu(x,t) is shifted above the equilibrium u=0 and Ev(x,t) is shifted below the equilibrium v=1. However, near the steady state (u,v)=(1,0), the mean
value Eu(x,t) is shifted below the
equilibrium u =1 and Eu(x,t)=0.


This paper deals with the problems of stochastic dynamic delay output feedback(SDDOF) stabilization and H∞ control for stochastic system. The stochastic system state is without time delay and is not available directly. The aim is the design of a full order SDDOF controller ensuring exponential mean-square stable and a prescribed H∞ performance level for the resulting closed-loop system. The sufficient conditions of stochastic stabilization and H∞ control for the existence of SDDOF controller are obtained and the expression of the desired controller is given in the form of matrix inequality. Moreover, an illustrate numerical example with simulation is given to demonstrate the applicability of the proposed design approach.


This study attempts to examine travel motivations from a hybrid cultural perspective in the context of Chinese niche hotels. Using an in-depth netnographic methodology, the paper analyzed 659 online reviews on 12 niche hotels from 6 travel websites to identify the motivations of Chinese independent travelers' hotel selection. The research findings revealed that travelers' motivations include the following: attractive environment, quality, uniqueness, spiritual well-being, traditional architecture, family togetherness, foreign style offerings and service, luxury amenities, and entertainment. These motivations can be classified into modern Chinese cultural motivations, traditional Chinese cultural motivations and foreign cultural motivations. The study identifies the characteristics of the market segment of Chinese independent travelers and offers valuable insights into the role of this emergent travel group. The theoretical implications suggest a hybridization effect of culturally oriented motivations showing that hotel choice and perhaps domestic tourism destination choice are driven by both Chinese and Western cultures. Management implications are discussed, and marketing suggestions are made to better understand what attracts this growing market segment in China.


The O2 pressure, saturation and capacity, the pH and CO2 pressure in the arterial blood of nonanaesthetized sheep were measured at two altitudes (1600 and 4340 metres). At high altitude sheep carriers of A haemoglobin had a mean arterial saturation significantly higher than the B haemoglobin carriers (86·4 ± 0·6 vs. 67·5 ± 1·0). The carriers of a mixture of A and B haemoglobins had an intermediate saturation: 77·0 ± 1·0. There was no significant difference among the three groups in arterial PO2, pH, PCO2, oxygen capacity and haematocrit.


blue lines indicate the flight path, satellite altitude, GMI swath, DPR Ku-band (or KuPR) swath and DPR Ka-band (or KaPR) swath, respectively. The three-dimensional rainfall is heaviest where there is red, and lightest where there is blue; note how three-dimensional measurements are only available from the DPR segment of the swath. The Ka-band swath was extended to 245km to match the Ku-band swath on 21 May 2018; refer to Iguchi (2020) for more details.

an apologia for Mary Piggott's highly recommended work. The book is not a textbook on cataloguing in the Hunter/Bakewell sense but rather it complements existing textbooks by including much of the interesting background information necessary for teaching cataloguing and for placing cataloguing in a true context of document retrieval (1). Nor is it a manual in the sense of the much older Manual of cataloguing practice by Bakewell because it lacks the cataloguing detail and depth of the manual (2). This work puts the information on cataloguing within the total sphere of librarianship and resists the temptation to make document retrieval the ultimate goal of all librarians. It refers to MARC or SWALCAP or PRECIS but always within the world of librarianship. It is a well-written, scholarly work compiled with the authority of an eminent academic; it is easy to read and to understand


A magnetoelectric (ME) dipole antenna with a single-layer microstrip line feeding network is proposed for either dual-linear or dual-circular-polarizations. To achieve better isolation, a hook and fork-shaped feedlines are designed to excite dual linear polarizations, which are combined with a quadratic hybrid to provide dual-circular polarizations. Furthermore, in the proposed feeding configuration, the isolation level is tuned properly according to the requirements. The operational bandwidth of the antenna (impedance bandwidth < -10 dB, Isolation > 30 dB (linear) and > 20 dB (circular), and Axial Ration < 3 dB) is 23% at 30 GHz. The average radiation efficiency and maximum gain of the antenna are calculated to be 95% and 9.2 dBi, respectively.


unpredictable movement, but also with art and its way of 'creating another reality that nevertheless reflects reality in this paradoxical way' (p. 225), while Charles Bernstein, with his edgier irreverence, forces a humorous polyphony to recast yet again the Bakhtinian chronotope; or, as Probstein nicely puts it, in Bernstein's work '[t]he present [is] stretched to the future in the form of a poetic line uniting time with space' (p. 241). I am reminded once again of Brodsky's fine account of Anna Akhmatova's ability to see the tragic events of her time 'first through the prism of the individual heart, then through the prism of history'. What remains so striking about such a vision, continues Brodsky, is that 'These two perspectives were brought into sharp focus through prosody, which is simply a repository of time within language'. Simply? Ian Probstein's The River of Time offers the help we need to gauge the real complexity of that word 'simply'.


In vivo uncoating of tobacco mosaic virus (TMV) was studied. As Shaw had reported, initiation of uncoating reaction takes place very efficiently. Coat protein is removed from the virus as a peptide which is precipitable with trichloroacetic acid. Short rod particles with partly exposed RNA are thus formed. Further uncoating to coat protein-free TMV-RNA (28S) seems to take place with very low efficiency which is comparable to that of formation of local lesions on the inoculated leaf. From the data on the intracellular distribution of these products of uncoating reaction, mechanisms and significance of these reactions are discussed.


Aiming at the problem of common-frequency jamming between airborne radars of same model, oblique projection polarization filtering technique was introduced into common frequency jamming countermeasure. The basic principle of oblique projection polarization filtering was analyzed; the anti-interference system's construction scheme and implementation steps for airborne radar were presented. Oblique projection polarization filtering method does not need signal and interference with orthogonal polarization, as long as they are difference, this method can completely suppress common frequency interference, and keep the signal amplitude and phase property, so it has extensive engineering application prospects. Computer simulation all proves the conclusion. Keywords-common frequency jamming; polarization filtering; two-axis tracking; anti-jamming; formation flight


Introduction: A
 nti-neoplastic agents that target vascular endothelial growth factor (VEGF) are known to have cardiovascular toxicities, principally hypertension, with a reported incidence of 21-40% in first-time users. Anti-VEGF induced hypertension can be challenging to control, and significant enough to lead to a dose reduction or discontinuation of the VEGF-targeted therapy, preventing patients from completing their cancer therapy.

 Methods:
 A single center prospective cohort of patients with cancer starting anti-VEGF therapy was compared to a retrospective control cohort that was 1:1 matched on gender, race, ethnicity, cancer type, and anti-VEGF therapy. For the prospective cohort, antihypertensive medications were started per an anti-VEGF hypertension algorithm. Elevated blood pressure was defined as consecutive blood pressure readings above 140/90 mmHg and control of blood pressure defined as consecutive readings <140/90 mmHg. Time to development of elevated blood pressure and blood pressure control, number of anti-hypertensive medications needed to control blood pressure were recorded.

 Results:
 The prospective cohort consisted of 31 patients which were 1:1 matched to 31 controls who received antihypertensives per standard of care. There were 50% female patients with mean age 61.0 ± 11.9 years. The most common anti-VEGF therapies received included lenvatinib (39%) and bevacizumab (33%) and the most common cancers being treated were kidney (43%) and liver (39%). In the prospective cohort
 ,
 24 (77%) developed hypertension greater than 140/90 mmHg compared to 18 (42%) in the control cohort (p=0.174). Of those who developed hypertension the time to control of blood pressure (<140/90mmHg) was improved in the prospective algorithmic approach to anti-VEGF hypertension compared to control (30.5 ± 35.6 days vs 104.9 ± 121.2 days respectively, p=0.007). More anti-hypertensive medications were used in the prospective cohort compared to the matched control (2.6 ± 1.1 vs 1.3 ± 1.0 respectively, p<0.001).

 Conclusion:
 A significant proportion of patients receiving VEGF-targeted therapy will develop hypertension. An algorithmic approach to anti-VEGF hypertension leads to earlier blood pressure control.


In this work, we evaluated the effectiveness of the automation capability offered by the ANKOM Dietary Fibre Analyzer to automate the current manual practice of fibre analysis (AOAC Method 991.43). Further, we also validated the automated fibre analysis via cross-checking with fibre analysis by the manual operation using fruit-, grainand nut-based samples. Automated fibre analysis showed relative standard deviations (TDF: 13.8%; IDF: 17.2%; and SDF: 24.6% at 95% CI reported by the AOAC in the method 991.43) that are consistent to the manual methods. Thus, this current work serves as a valuable assessment of a novel filtration system with disposable filter bag developed by ANKOM Technology. The new instrumentation automates the enzymatic-gravimetric processing by eliminating several laborious, time-consuming manual operations, saving over 50% of analyst time that converts to 60% overall cost savings and improved laboratory productivity, efficiency and safety. Industry-wide adoption of such instrumentation not only reduces the analysis cost but also harmonises the fibre amounts reported among the global food and beverage industry.

Spatial regulation zoning is an effective way in land use development to reduce its negative impact on regional ecological environment. We developed a spatial regulation zoning method based on the ecological tolerance for each land use type using geographic information system(GIS)and applied it to the regulation zoning in Lianyungang City,China.This proposed method includes three steps:(1)Identifying ecological limitation elements for each land use type;(2)Data procession and extraction; and(3) Spatial regulation zoning based on established regulation rules associated with the overlay of limitation element maps. Our results indicate that(1)The whole study area can be divided into five levels of regulation zones:The non-regulation zone(84. 38%,6328. 5km2),the mild-regulation zone(11. 53%,864. 8km2),the moderate-regulation zone(2.60%,195. 2km2),the severe-regulation zone(0. 95%,70. 6km2),and the extremely severe-regulation zone(0. 54%,40. 8km2);(2)Spatial regulation rules established for each level reflect the corresponding ecological limitation elements for each land use type;(3) The assessment of the land use planning using our proposed method suggested that the scheme of our proposed method is suitable for the regulation zone to effectively reduce the negative impact of land use development on the regional ecosystems;and(4) GIS-based spatial regulation zoning provides an effective framework in land use planning to assess the spatial characteristics of the potential ecological impacts of the land use development.
