Microscopic Derivation of Ginzburg-Landau Theory

We give the first rigorous derivation of the celebrated Ginzburg-Landau (GL) theory, starting from the microscopic Bardeen-Cooper-Schrieffer (BCS) model. Close to the critical temperature, GL arises as an effective theory on the macroscopic scale. The relevant scaling limit is semiclassical in nature, and semiclassical analysis, with minimal regularity assumptions, plays an important part in our proof.
Contextual Constructivism: The Impact of Culture on the Learning and Teaching of Science.

Though rooted in neo-Piagetian research, constructivism is an avenue of research that departed from the neo-Piagetian mainstream 20 yearn ago and has continued on a distinct path of development. For constructivists, learning is not knowledge written on, or transplanted to, a person's mind as if the mind were a blank slate waiting to be written on or an empty gallery waitiag to be filled. Teaching, furthermore, is mediating. A constructivist teacher works at the interface of curriculum and student to bring them together in a way that is meaningful for the learner. Constructivists use the metaphor of construction because it aptly summarizes the view that individuals build knowledge. Carrying the metaphor to its logical conclusion, construction implies a foundation upon which, or a context in which the individual builds knowledge. Contextual constructivism is thus about understanding the fundamental, culturally based beliefs that both students and teachers bring to class, and how these beliefs are supported by culture. Contextual constructivi6trJ not only raise new research questions, they also call for a new research paradigm. The focus on contextualization means that qualitative, especially ethnographic techniques are to be preferred. (Over 75 references are included.)

UV-Assisted Photochemical Synthesis of Reduced Graphene Oxide/ZnO Nanowires Composite for Photoresponse Enhancement in UV Photodetectors

The weak photon absorption and high recombination rate of electron-hole pairs in disordered zinc oxide nanowires (ZNWs) limit its application in UV photodetection. This limitation can be overcome by introducing graphene sheets to the ZNWs. Herein we report a high-performance photodetector based on one-dimensional (1D) wide band-gap semiconductor disordered ZNWs composited with reduced graphene oxide (RGO) for ultraviolet (UV) photoresponse enhancement. The RGO/ZNWs composites have been successfully synthetized through UV-assisted photochemical reduction of GO in ZNWs suspension. The material characterizations in morphology, Raman scattering, and Ultraviolet-visible light absorption verified the formation of graphene sheets attached in ZNWs network and the enhancement of UV absorption due to the introduction of graphene. In comparison with photodetectors based on pure ZNWs, the photodetectors based on RGO/ZNWs composite exhibit enhanced photoresponse with photocurrent density of 5.87 mA·cm−2, on/off current ratio of 3.01 × 104, and responsivity of 1.83 A·W−1 when a UV irradiation of 3.26 mW·cm−2 and 1.0 V bias were used. Theory analysis is also presented to get insight into the inherent mechanisms of separation and transportation of photo-excited carriers in RGO/ZNWs composite.
Positive correlation of the serum angiopoietin-like protein 3 levels with the aortic augmentation index in patients with coronary artery disease

Purpose Angiopoietin-like protein 3 (ANGPTL3) plays an important role in lipid metabolism and angiogenesis and is elevated in familial hypercholesterolemia, metabolic syndrome, and insulin resistance. This study aims to evaluate the relationship between the fasting serum ANGPTL3 levels and the aortic augmentation index (AIx) in patients with coronary artery disease (CAD). Materials and methods Fasting blood samples were obtained from 100 patients with CAD. The AIx was measured using a validated tonometry system (SphygmoCor). The serum ANGPTL3 levels were assessed using a commercial enzyme-linked immunosorbent assay kit. Results The aortic AIx values were higher in female patients with CAD (P=0.003) than those in male patients with CAD. The univariate linear analysis of the aortic AIx values reveals that the height (r=−0.363; P<0.001) and body weight (r=−0.350; P<0.001) were negatively correlated, whereas the age (r=0.202; P=0.044) and logarithmically transformed ANGPTL3 (log-ANGPTL3, r=0.357; P<0.001) were positively correlated with the aortic AIx values in patients with CAD. The multivariate forward stepwise linear regression analysis of the factors significantly associated with the aortic AIx revealed that the height (β=−0.269; adjusted R2 change=0.123; P=0.007) and serum log-ANGPTL3 level (β=0.259; adjusted R2 change=0.051; P=0.010) were independent predictors of the aortic AIx values in patients with CAD. Conclusion The fasting serum ANGPTL3 level positively correlated with the aortic AIx values among patients with CAD.
Direction-Dependent Effects of Combined Static and ELF Magnetic Fields on Cell Proliferation and Superoxide Radical Production

Proliferation of human umbilical vein endothelial cells was stimulated by a nearly vertical 60 or 120 μT static magnetic field (MF) in comparison to cells that were shielded against MFs. When the static field was combined with an extremely low frequency (ELF) MF (18 Hz, 30 μT), proliferation was suppressed by a horizontal but not by a vertical ELF field. As these results suggested that the effects of an ELF MF depend on its direction in relation to the static MF, independent experiments were carried out to confirm such dependence using 50 Hz MFs and a different experimental model. Cytosolic superoxide level in rat glioma C6 cells exposed in the presence of a nearly vertical 33 μT static MF was increased by a horizontal 50 Hz, 30 μT MF, but not affected by a vertical 50 Hz MF. The results suggest that a weak ELF MF may interact with the static geomagnetic field in producing biological effects, but the effect depends on the relative directions of the static and ELF MFs.
Diagnostic Value of Fine Needle Aspiration Cytology in Gouty Tophi

UNLABELLED BACKGROUND The diagnosis of gout can be problematic when the presentation is atypical and serum uric acid is borderline elevated. Demonstration of monosodium urate (MSU) crystals in fine needle aspiration (FNA) smears from nodular masses clinically suspected to be tophi establishes the diagnosis unequivocally. CASES Of the 7 cases in this study, 4 were suspected clinically to have gouty tophi. Giant cell tumor of tendon sheath, giant cell tumor of bone and metastatic tumor with multicentric involvement of bone were the clinical diagnoses in 1 case each. Serum uric acid levels high enough to be in the diagnostic range for gout were reported in 3 cases, within normal limits in 3 cases and low in 1 chronic alcoholic patient. Bright field microscopy of FNA smears revealed singly scattered or stacks of MSU crystals with variable number of inflammatory cells, with or without foreign body giant cells in 6 cases. In 1 patient, FNA showed stacks of MSU crystals only. Characteristic birefringence of MSU crystals was observed on polarizing microscopy. CONCLUSION FNA demonstration of MSU crystals on polarizing microscopy can easily establish the nature of the nodules in and around the joints and in soft tissue as gouty tophi and is thus an investigation differentiating this lesion from other masses clinically simulating it.
Catastrophic Health Expenditure in Iran: A Review Article

Background: One of the main challenges of healthcare systems is to protect people from consequences of health expenditures. Such expenditures may lead to catastrophic financial loss in families so that many people deny demanding necessary healthcare services, which results in harms to their health status. The aim of this systematic review was to investigate the catastrophic health expenditures trend and its related factors in Iran. Methods: This systematic review and meta-analysis was conducted on studies conducted between 1984 and 2014. Data were collected through searching electronic databases and searching engines of PubMed, Scopus, EconLit, Google Scholar, Science Direct, MagIran, and Scientific Information Database (SID). The random effects were used with 95% confidence interval for the meta-analysis. Results: Out of 561 initially retrieved articles, finally 42 were included in the final analysis. The studies were conducted between 1984 and 2014. The overall proportion of exposure to catastrophic health expenditure in Iran was 7.5% (95% CI, 6.2 – 9.1). In the urban and rural areas, the proportion was 2.3% (95% CI, 1.8 – 2.9) and 3.4% (95% CI, 2.8 – 4.1) respectively. The overall proportion of exposure to the catastrophic health expenditure in hospitals was 35.9% (95% CI, 23.5 – 54.3). Conclusion: The catastrophic expenditures proportion of healthcare is relatively high in Iran and the government is expected to adopt effective measures in this regard, especially for the inpatient care. There are needs for special supporting policies for the financial protection of specific patients, the poor and villagers.
The Intergenerational Impact of Genetic and Psychological Factors on Blood Pressure (InterGEN) Study

The Intergenerational Impact of Genetic and Psychological Factors on Blood Pressure (InterGEN) study aims to delineate the independent and interaction effects of genomic (genetic and epigenetic) and psychological–environmental (maternally perceived racial discrimination, mental health, and parenting behavior) factors on blood pressure (BP) among African American mother–child dyads over time. The purpose of this article is to describe the two-step genetic and epigenetic approach that will be executed to explore Gene × Environment interactions on BP using a longitudinal cohort design. Procedure for the single collection of DNA at Time 1 includes the use of the Oragene 500-format saliva sample collection tube, which provides enough DNA for both the Illumina Multi-Ethnic Genotyping and 850K EPIC methylation analyses. BP readings, height, weight, percentage of body fat, and percentage of body water will be measured on all participants every 6 months for 2 years for a total of 4 time points. Genomic data analyses to be completed include multivariate modeling, assessment of population admixture and structure, and extended analyses including Bonferroni correction, false discovery rate methods, Monte Carlo approach, EIGENSTRAT methods, and so on, to determine relationships among both main and interaction effects of genetic, epigenetic, and psychological environmental factors on BP.
Estimating common dolphin bycatch in the pole-and-line tuna fishery in the Azores

Small-scale artisanal fisheries can have a significant negative impact in cetacean populations. Cetacean bycatch has been documented in the pole-and-line tuna fishery in the Azores with common dolphins being the species more frequently taken. Based on data collected by observers on ∼50% of vessels operating from 1998 to 2012, we investigate the influence of various environmental and fisheries-related factors in common dolphin bycatch and calculate fleet-wide estimates of total bycatch using design-based and model-based methods. Over the 15-year study dolphin bycatch occurred in less than 0.4% of the observed fishing events. Generalized additive modelling results suggest a significant relationship between common dolphin bycatch and duration of fishing events, sea surface temperature and location. Total bycatch calculated from the traditional stratified ratio estimation approach was 196 (95% CI: 186–205), while the negative binomial GAM estimated 262 (95% CI: 249–274) dolphins. Bycatch estimates of common dolphin were similar using statistical approaches suggesting that either of these methods may be used in future bycatch assessments for this fishery. Our work shows that rates of common dolphin bycatch in the pole-and-line tuna fishery in the Azores are low, despite considerable variations between years. Dolphins caught were released alive although the fate of these individuals is unknown. Continued monitoring will provide a better understanding of dolphin bycatch and more accurate estimates essential in the development of potential mitigation measures.
Enhancing Toughness of Low-Density Polyethylene Filaments Through Infusion of Multiwalled Carbon Nanotubes and Ultrahigh Molecular Weight Polyethylene

We report enhancement in fracture strain and toughness of low-density polyethylene by infusing multiwalled carbon nanotubes (MWCNT) and a second-phase polymer; ultrahigh molecular weight polyethylene (UHMWPE). Infusion of MWCNT improved strength and modulus by about 23 and 57%, respectively, but reduced fracture strain (∼45%) and toughness (∼36%). UHMWPE was then dispersed as a minor phase, and the resulting nanocomposites showed a 55% increase in toughness without any loss of strength or modulus. The loading of MWCNT and UHMWPE was 2 and 8% by weight, respectively. Nanocomposites were in the form of filaments and were extruded through a melt extrusion process. Differential scanning calorimetry and X-ray diffraction studies revealed increase in crystallinity and crystallite size. Scanning electron microscope micrographs showed sliding of polymer interfaces and changes in fracture process. Strain hardening experiments also showed improvement in strength and modulus but reduction in toughness. POLYM. ENG. SCI., 2011. © 2010 Society of Plastics Engineers.
Strength Prediction for Jute Polyester Composite for Transverse Fiber Reinforcement

The composites are very useful in present era due to weight saving and economy of construction by tailoring material to structural application. In order to save the crop from extinction and to ensure a reasonable return to the farmers, non-traditional outlets have to be explored for the jute fiber. Jute fiber due to its adequate tensile strength and good specific modulus enjoys the right potential for usage in composites. In the present work the experimentations were conducted for the strength of composite by varying volume fraction of fiber in the range of 12 % to 42 %. The tensile strengths of specimen were measured as per ASTM D 3039-76, and the amount of voids fraction is measured to evaluate actual contributing volume fraction of fiber and volume fraction of matrix. The prediction of strength is proposed by considering efficiency terms f η and m η representing effective contribution of fiber and matrix and an additional efficiencies t1 η and t 2 η representing effectiveness from fiber and matrix for transverse reinforcement case. The results are also compared with FEM results obtained using standard package ANSYS and IDEAS. The results obtained by experiments are observed to be within 0.9 % with developed model and 2.85 % and 3.21 % with ANSYS and IDEAS simulated results. The deviation of proposed model is observed under predictive for experimental data available in literature while the experimental results obtained in present work is also found to be on lower side to that of available predictive models from literature.
Environmental heterogeneity and biotic interactions mediate climate impacts on tropical forest regeneration

Predicting the fate of tropical forests under a changing climate requires understanding species responses to climatic variability and extremes. Seedlings may be particularly vulnerable to climatic stress given low stored resources and undeveloped roots; they also portend the potential effects of climate change on future forest composition. Here we use data for ca. 50,000 tropical seedlings representing 25 woody species to assess (i) the effects of interannual variation in rainfall and solar radiation between 2007 and 2016 on seedling survival over 9 years in a subtropical forest; and (ii) how spatial heterogeneity in three environmental factors—soil moisture, understory light, and conspecific neighborhood density—modulate these responses. Community‐wide seedling survival was not sensitive to interannual rainfall variability but interspecific variation in these responses was large, overwhelming the average community response. In contrast, community‐wide responses to solar radiation were predominantly positive. Spatial heterogeneity in soil moisture and conspecific density were the predominant and most consistent drivers of seedling survival, with the majority of species exhibiting greater survival at low conspecific densities and positive or nonlinear responses to soil moisture. This environmental heterogeneity modulated impacts of rainfall and solar radiation. Negative conspecific effects were amplified during rainy years and at dry sites, whereas the positive effects of radiation on survival were more pronounced for seedlings existing at high understory light levels. These results demonstrate that environmental heterogeneity is not only the main driver of seedling survival in this forest but also plays a central role in buffering or exacerbating impacts of climate fluctuations on forest regeneration. Since seedlings represent a key bottleneck in the demographic cycle of trees, efforts to predict the long‐term effects of a changing climate on tropical forests must take into account this environmental heterogeneity and how its effects on regeneration dynamics play out in long‐term stand dynamics.
The Intimate Partner Violence Responsibility Attribution Scale (IPVRAS)

The aim of this study is to present a psychometrically sound instrument to assess intimate partner violence offenders’ responsibility attributions: the Intimate Partner Violence Responsibility Attribution Scale. The scale was administrated to 423 adult male intimate partner violence offenders court-mandated to a community-based intervention program. A three factor structure (responsibility attribution to the legal system, responsibility attribution to the victim, and responsibility attribution to the offender personal context) was supported using confirmatory factor analysis. Reliability of the scales in this study was estimated using Cronbach’s alpha, ρ and greatest lower bound. The Intimate Partner Violence Responsibility Attribution Scale correlated in theoretically expected ways with variables used to assess construct validity (system blaming, problems with partner, and responsibility assumption) and with variables used to assess criterion-related validity (satisfaction with legal system, victim-blaming attitudes, alcohol consumption, hostile sexism, stressful life events, social desirability, impulsivity and household income). Results support the validity and reliability of the Intimate Partner Violence Responsibility Attribution Scale.
Quantization of quasi-Lie bialgebras

The main result of this paper is the construction of quantization functors of quasi-Lie bialgebras. We first recall the situation of this problem in the theory of quantum groups. This theory started, on the mathematical side, with the discovery by Drinfeld and Jimbo of a noncocommutative deformation Uqg, in the category of Hopf algebras, of the enveloping algebra of a Kac-Moody Lie algebra. This discovery was soon related to important developments in knot theory and representation theory. At the same time, Drinfeld developed a program of formal deformation of enveloping algebras in the category of Hopf algebras (such a deformation is called a quantized universal enveloping, or QUE, algebra). Any QUE algebra leads to Lie algebraic data (more precisely, a Lie bialgebra), its “classical limit”, and Drinfeld asked whether a QUE algebra could be reconstructed from its classical limit; this question was solved by Etingof and Kazhdan, who constructed “quantization” functors from the category of Lie bialgebras to that of QUE algebras. The introduction of Uqg was motivated by mathematical physics, more precisely, the Wess-Zumino-Novikov-Witten model in conformal field theory. One of the mathematical incarnations of this model is the differential system obeyed by its correlation functions, the Knizhnik-Zamolodchikov (KZ) system. The relation between the KZ system and Uqg was first made precise by Kohno, who expressed the monodromy representation of the KZ system using the representation theory of Uqg, when g is finite dimensional. This theorem was then reproved by Drinfeld, who developed for this purpose the theory of quasi-Hopf algebras (QHAs). The main novel feature of this theory with respect to that of Hopf algebras is that the coassociativity axiom of the coproduct is weakened: namely the coassociativity identity (id⊗Δ)(Δ(x)) = (Δ ⊗ id)(Δ(x)) for x ∈ A is replaced by (id⊗Δ)(Δ(x)) = Φ(Δ⊗ id)(Δ(x))Φ−1, where Φ ∈ A⊗3 is invertible and subject to a “pentagon” consistency condition. Similarly to Hopf algebras, QHAs lead to tensor categories via their categories of representations; finite-dimensional QHAs play an important role in the ongoing program of classification of finite tensor categories. Drinfeld also developed a program for constructing a particular class of QHAs (the quasi-Hopf quantum universal enveloping, or QHQUE algebras) using formal
Experimental investigation of wind effect on solar panels

Photovoltaic Solar Panels for electricity generation are outdoor low-rise structures that are vulnerable to damage by the wind. The existing building codes do not contain information about the impact of the wind on these structures and hence do not provide comprehensive guidelines to mitigate such impact. The present study is a contribution to the ongoing efforts to codify the wind loading on solar panels. In this study, experimental investigations were conducted on the scaled model of a ground-mounted solar panel structure whose surface is geometrically similar to an inclined flat plate and mounted on three-legged support. The panel comprises of gaps, which divide it into an array of 24 smaller units. The objective of this study is to determine the wind pressure distribution on the panel and characterize the flow dynamics around it. The pressure measurements were conducted through taps connected to pressure transducers for both head-on (0o, 180o) and oblique (30o, 150o) wind directions with the panel inclined at 25o and 40o. The results indicate that larger inclination angles increased the wind forcing on the panel. At a panel inclination of 25o, velocity fields of the wind approaching head-on at 0o were captured to examine the flow field using particle image velocimetry (PIV) technique. The mean and turbulent velocities around the panel are computed and presented. The results indicate that the gaps between each unit of the panel influenced the wind loading pattern on the solar panel.
