Problem-Based Methods As A Means Of Compositional Thinking Development Of Artist Students

The article discusses the problems of a professional art education, teaching one of the main academic disciplines composition, which studies the laws of art forms creation using the means of artistic expression, techniques and the organization of image perception. A compositional way of thinking according to the authors is of an artistic and plastic nature and is based on operating the language of art and is aimed at creating a new, holistic, original artistic image. The authors distinguish a compositional thinking as one of the most important professional qualities of the artist, and disclose the methodology of its formation among students of artistic directions. The process of teaching to compose: creation of a picture, a drawing, a sculpture or design an object cannot be built as a simple linear process of teaching image methods, compositional rules and techniques. The author’s methodology is based on the method of problem tasks, which involves setting a creative task, creating a problem situation; comprehension, acceptance and resolution of the problem when students master the generalized methods of artistic and creative activity. Moreover, the creative process is considered as a series of successive stages associated with the work of a productive or creative imagination requiring the provision of visual or other information in the process of work. The article presents the results of the ascertaining and forming stages of experimental work on the development of compositional thinking of artist students in the development of expressive means, as well as compositional techniques and rules. 2357-1330 © 2020 Published by European Publisher.
Grand canonical Monte Carlo simulation study of water structure on hydrophilic mesoporous and plane silica substrates

The radial distribution functions obtained by grand canonical Monte Carlo simulations of water adsorbed on disordered mesoporous and ordered plane silica surfaces at 300 K are investigated. The plane surfaces are crystallographic faces of cristobalite. The disordered mesoporous Vycor-like glass was previously obtained by off-lattice reconstruction known to reproduce in a realistic way the geometrical complexity of the real Vycor of high specific surface, in terms of surface area, chord distribution, and correlation peak in small angle neutron scattering spectra. The SPC model is used for water, and water–substrate interactions are described by the PN-TrAZ model without any adjustment of parameter. It is shown that the water confined in Vycor is slightly more structured than bulk water, mainly due to the interaction of the first layer with the substrate. The vapor pressure is reduced so as to obtain a mono-layer coverage for each surface. On ordered crystalline faces, the water mono-layer has long range co.
Atmospheric deposition and land-surface runoff driven nutrient flushing in Ganga River (India)

ABSTRACT Disproportionate addition of nutrients can alter the nutrient stoichiometric balance of surface water bodies. In the present study, we investigated the atmospheric deposition (AD) and runoff-induced nutrient enrichment and N:P stoichiometric shifts in the Ganga River along a 35 km stretch of Varanasi city. The region receives 8–42 kg ha−1 of reactive-N (NO3 − + NH4 +) and 0.40–3.10 kg ha−1 of PO4 3- through AD annually. The most polluted Rajghat Site receives ~770.50 tons of reactive-N (Nr) and ~64.50 tons of PO4 3- annually as AD input in the sub-watershed; and ~25.10 tons of Nr and 2.09 tons of PO4 3- directly on the water surface. Concentrations of nutrients in surface runoff increased with AD input irrespective of land use. Among land use categories, the runoff nitrate was highest from agricultural catchment while NH4 + and PO4 3- were highest from urban areas. The study showed that the AD-runoff coupled with additional supplies could substantially alter the overall load and stoichiometric ratios of critical nutrients with a consequent effect on ecological functioning of the river in long-run.
Surface Modification of Catalysts via Atomic Layer Deposition for Pollutants Elimination

In recent years, atomic layer deposition (ALD) is widely used for surface modification of materials to improve the catalytic performance for removing pollutants, e.g., CO, hydrocarbons, heavy metal ions, and organic pollutants, and much progress has been achieved. In this review, we summarize the recent development of ALD applications in environmental remediation from the perspective of surface modification approaches, including conformal coating, uniform particle deposition, and area-selective deposition. Through the ALD conformal coating, the activity of photocatalysts improved. Uniform particle deposition is used to prepare nanostructured catalysts via ALD for removal of air pollutions and dyes. Area-selective deposition is adopted to cover the specific defects on the surface of materials and synthesize bimetallic catalysts to remove CO and other contaminations. In addition, the design strategy of catalysts and shortcomings of current studies are discussed in each section. At last, this review points out some potential research trends and comes up with a few routes to further improve the performance of catalysts via ALD surface modification and deeper investigate the ALD reaction mechanisms.
Interactive effect of boron and zinc on growth and metabolism of mustard

Abstract Mustard (Brassica campestris L.) cv. T9 was grown in refined sand at three levels of boron (B), deficient (0.0033 ppm), normal (0.33 ppm), and excess (3.3 ppm), each at three levels of zinc (Zn), low (0.00065 ppm) adequate (0.065 ppm), and high (6.5 ppm). The B deficiency effects were accentuated by low zinc viz., the decreased biomass, B and Zn concentrations in leaves and seeds and the activity of carbonic anhydrase and accumulation of reducing sugars and stimulated activities of peroxidase, ribonuclease, and acid phosphatase in B deficient leaves were aggravated further. Synergism was also observed between the two nutrients when both B and Zn were in excess together as excess B accelerated the effects of high Zn by lowering further the reduced biomass, economic yield, and carbonic anhydrase activity and raised further the increased concentration of B and Zn in leaves and seeds, reducing sugars and activity of peroxidase obtained in excess Zn. In mustard, additive effects of high Zn and low B was reflected when high Zn increased the reduced biomass, seed yield, leaf B, and decreased the stimulated activities of peroxidase, ribonuclease, acid phosphatase, and high concentration of non‐reducing sugars to some extent in low B.

Intersection of Polycystic Ovary Syndrome and the Gut Microbiome

Abstract The etiology of polycystic ovary syndrome (PCOS) remains unclear, although studies indicate that both genetic and environmental factors contribute to the syndrome. In 2012, Tremellen and Pearce proposed the idea that dysbiosis of the intestinal (gut) microbiome is a causative factor of metabolic and reproductive manifestations of PCOS. In the past 5 years, studies in both humans and rodent models have demonstrated that changes in the taxonomic composition of gut bacteria are associated with PCOS. Studies have also clearly shown that these changes in gut microbiota are associated with PCOS as opposed to obesity, since these changes are observed in women with PCOS that are both of a normal weight or obese, as well as in adolescent girls with PCOS and obesity compared with body mass index- and age-matched females without the disorder. Additionally, studies in both women with PCOS and rodent models of PCOS demonstrated that hyperandrogenism is associated with gut microbial dysbiosis, indicating that androgens may modulate the gut microbial community in females. One study reported that the fecal microbiome transplantation of stool from women with PCOS or exposure to certain bacteria resulted in a PCOS-like phenotype in mice, while other studies showed that exposure to a healthy gut microbiome, pre/probiotics, or specific gut metabolites resulted in protection from developing PCOS-like traits in mice. Altogether, these results suggest that dysbiosis of the gut microbiome may be sufficient to develop PCOS-like symptoms and that modulation of the gut microbiome may be a potential therapeutic target for PCOS.
Reactions of platinum(II) aqua complexes. 1. Multinuclear (platinum-195, nitrogen-15, and phosphorus-31) NMR study of reactions between the cis-diamminediaquaplatinum(II) cation and the oxygen-donor ligands hydroxide, perchlorate, nitrate, sulfate, phosphate, and acetate

Reactions in aqueous solution between cis-[Pt(NH)(HO)] (C1O) and anions A (C1O , OH, NO , SO , HPO , CHCO ) have been studied with use of Pt, N, and, for phosphate, P NMR. The monohydroxo-bridged complex (Pt(NH)(HO))(μ-OH) has been obtained in solution by reaction of [Pt(NH)(μ-OH)] with acid or as an intermediate in the formation of these oligomers from cis-Pt(NH)(OH)(HO). Perchlorate does not coordinate. Nitrate and sulfate each gives a complex cis-Pt(NH)(A)(HO), with A unidentate. In acidic solution (pH 1.5), phosphate gives only cis-Pt(NH)(OPOH)(HO). When deprotonated, this complex is in equilibrium with (Pt(NH))(μ-OH)(μ-POH) and other complexes containing bridging phosphate. Reaction with oxygen gives blue solids and solutions. Analogous phosphate complexes are formed with methylamine and ethylenediamine, although blue solutions with methylamine are obtained only after prolonged exposure to light. In solution, acetate gives cis-P(NH)(OCCH)(HO), and Pt(NH)(OCCH), with smaller amounts of (Pt(NH))(μ-OH)(μ-OCCH). With perchlorate, a solid [Pt(NH)(OCCH)]C1O-HO crystallizes, which probably contains bridging acetate. Solutions turn blue-black when heated, indicating that oligomers with mixed oxidation states of platinum form. Solid cis-Pt(NH)(OCCH)-2HO may be isolated. It is quite soluble in water.
Modulation of Oral Biofilm and Immune Response Associated to Mucosa with Probiotic Bacteria as a Potential Approach in the Prevention of Dental Caries: A Systematic Review

Background: A variety of approaches have been developed for the control of dental caries, a pathology with high incidence and prevalence worldwide. The use of probiotic strains for the modulation of dental biofilm in the prevention of caries has been studied, but the available evidence shows varied methodologies; and the strains tested differ from one study to another. Objective: To analyse through a systematic review of clinical trials, the efficacy of using probiotic strains to prevent dental caries. Methods: A search was made in the scientific bases PubMed, Cochrane and Science Direct, prioritizing randomized double and triple-blind clinical trials from 2010 to 2020, including a total of 20 studies to be analysed. The selection criteria were consistent with the Preferred Reporting Items for Systematic Reviews protocol. Results: Within the studies, different types of probiotic bacteria were analysed, dominating Lactobacillus Paracasei. While most clinical trials show a favorable response in terms of a significant reduction of Streptococcus mutans in the oral microbiota, very few studies evaluated salivary pH and sIgA levels. Conclusion: The heterogeneity of the studies analysed and the multifactorial nature of dental caries do not allow us to ensure that probiotic therapy is completely effective in preventing this pathology. Although probiotic therapy can help by regulating the microbiological factor, there are other determinants that can favor the development of caries and that are barely approached in their relationship with bacteriotherapy. Future studies that homogeneously evaluate the use of probiotics could give us a clearer idea of their effectiveness.
Experimental dispersion of the third-order optical susceptibility of graphene oxide

We experimentally determined the dispersion of third-order optical susceptibility χ(3) of graphene oxide (GO) in the visible region (450 - 750 nm) by combining spectroscopic ellipsometry and ultrafast pump and probe spectroscopy in the femtosecond regime. In order to mitigate the damage of wide-spectrum laser to photonic devices, GO has become a promising material for optical limiting (OL) devices. However, there is no report about the χ(3) dispersion of GO, which is a complex quantity that directly corresponds to nonlinear refraction and absorption and is a crucial parameter for the manipulation and application of its OL properties. Here, we identified that the linear optical response of GO shows a flat dispersion in the visible region. In contrast, its nonlinear optical response exhibits saturable absorption (SA) at the short wavelength and reverse saturable absorption (RSA) at the long wavelength. These results propel the application of GO in the broadband OL devices based on the RSA behavior. In addition, by controlling the fraction of sp2 and sp3 hybridizations, it also provides opportunities to tailor the NLO properties and OL performance of GO.
A X-Ray Analysis of the Structure of Water.

X‐ray diffraction patterns of water were obtained at five temperatures: 1.5°, 13°, 30°, 62°, and 83°C. The radiation was Cu Kα and Mo Kα, monochromated by reflection from a rocksalt crystal. Radial distribution curves for water at the five temperatures were obtained by a Fourier analysis of the x‐ray intensity curves. The first peak is only partially resolved, and it is not possible to interpret the distribution curves uniquely in terms of a definite number of neighbors at definite distances. The results can be interpreted in terms of a structure in which the tendency of a water molecule to bond itself tetrahedrally to 4 neighboring molecules is only partially satisfied.

Doing feminist physical cultural research in digital spaces: reflections, learnings and ways forward

ABSTRACT In this article we draw on our varied experiences of conducting feminist sport and leisure scholarship in digital spaces to offer some reflections, learnings and ways forward for navigating the challenges of digital and social media research. The paper outlines our methodological and ethical relationships to doing feminist research with and about women and girls, taking Margaret McClaren’s activist lens as a starting point to consider issues of positionality and reflexivity when researching lived experiences of gender in digital spaces. We then analyse our own actions across four dimensions of the research process: (1) connecting with communities and participants, (2) conceptualising and managing data, (3) navigating the ethics of representation and (4) vulnerabilities and self-care. In sharing our learnings from a range of projects, this paper offers insights into the methodological implications of conducting digital research on the moving body, as well as practical considerations for those doing feminist research on sporting and physical cultures in digital spaces. This article contributes to emerging conversations amongst qualitative sport and physical activity researchers about the challenges of digitisation for feminist engagements with power, context and situated knowledges.
Aplicação retrospectiva dos escores KDPI e EPTS em pacientes de um Centro de Transplantes Brasileiro / Retrospective application of the KDPI and EPTS scores in patients from a Brazilian Transplant Center

Introduction: KDPI and EPTS are scores implemented in the United States in 2014 to guide the allocation of kidney grafts. The objective of this work is to correlate values of these scores with outcomes of kidney transplants performed in a Brazilian Transplant Center, evaluating their ability to predict prognosis in this population. Methods: Observational, individual, longitudinal and retrospective study with 163 recipient-donor pairs of kidney transplants with deceased donors, carried out between 2012 and 2017, with follow-up until 2019. Results: Patients with grafts with KDPI less than or equal to the median had lower mortality after one year (p = 0.02); lower graft loss rate up to one year (p = 0.00) and after one year (p = 0.03) and lower creatinine level (p = 0.00). Recipients with EPTS less than or equal to the median had a significantly lower graft loss rate, compared to those with values greater than the median (p = 0.01). The correlation coefficient between KDPI and EPTS was of about 0.016 (p = 0.84). Conclusion: KDPI proved to be an objective and easy to apply tool to predict prognosis and, thus, direct the kidneys to be transplanted. EPTS showed a promising character for the evaluation of kidney recipients. These data can be complemented with future national studies for possible validation and implementation of such scores in the country. Finally, it was observed that there was no direct correlation between the KDPI values of grafts and the EPTS values of its recipients, distancing from what is recommended by the North American literature.
Design of Insertion Mechanism for Cannula Flexible Needle Based on TRIZ

Insertion mechanism is one of the basic parts in robot assisted surgery system. In this study, we designed an insertion mechanism for a cannula flexible needle based on TRIZ. According to the degree of freedom (DOF) requirement for the insertion movements, the nesting principle was used to solve the complexity problem of the traditional design. The nested screw nut mechanism effectively reduced the volume and the weight of the insertion mechanism and made the whole structure more compact. The extraction principle and the separation principle were used to solve the supporting problem, and the scheme of separated supporting blocks was proposed. According to the finite element analysis results, the initial supporting position of each supporting block was obtained. Then the substance-field analysis method was utilized to solve the dynamic supporting problem. An elastic connecting band was introduced linking each supporting block to realize a linkage motion of the supporting blocks. This not only improved the supporting effect by adjusting each block to the right position in real time, but it can reset each block to its original position as well. Finally, we used the proposed mechanism to perform the insertion experiments, and the error was within 0.4mm, which confirmed the validity of the proposed insertion mechanism.
Properties of aliphatic polyesters with n-paraffinic side branches

Effect of ethyl and n-octyl branches on the properties of poly(ethylene adipate) (PEA) and poly(butylene succinate) (PBS) were investigated. Glass transition and melting temperature, crystallinity, melt viscosity, and spherulite growth rate were decreased with an increase in the degree of the chain branches. Introduction of ethyl branches as well as n-octyl branches into PEA did not improve the tensile strength and modulus, while it reduced elongation and tear strength significantly. The presence of glycerol units less than 0.05 mol/mol of diacid units in PEA as well as in PSB also brought about damaging effects on the properties. Additional amount of glycerol units in the polyesters resulted in the formation of gel. However, addition of n-octyl branches improved elongation and tear strength of PBS considerably without a notable decrease of tensile strength and modulus. © 2000 John Wiley & Sons, Inc.

Language, Psychology, and New New Media: The Hyperpersonal Model of Mediated Communication at Twenty-Five Years

Research on the hyperpersonal model originally described how the substitution of language for nonverbal cues, necessitated by text-based computer-mediated communication systems, transforms users’ reception, self-presentation, composition, and reciprocal reinforcement of messages in ways that create socially desirable relationships online. This article reviews the model after 25 years. It explicates the original model and mentions a sample of illustrative findings. It reflects on the state of internet diffusion and research traditions in the 1990s that affected the model’s original focus, and how these conditions have changed. It enumerates contexts that continue to meet the model’s original boundary assumptions, and some boundary expansions. It explores ways in which the model’s principles extend into contemporary multi-modal social media. It illustrates the evolutionary applicability of the model through cases of deceptive online romances, including contemporary online romance scams. It concludes by suggesting future research examining how many contemporary social media performances and responses comport with and illustrate the model’s tenets, at scale.
