The Role of Psychology in Addressing Worldwide Challenges of Poverty and Gender Inequality
Authors: Antonucci Toni C. , Bial Martha , Cox Carole , Finkelstein Ruth , Marchado Laura
Published: June 2019

Abstract. The United Nations has identified 17 Sustainable Development Goals (SDGs) designed to improve the health and well-being of the world’s most vulnerable populations. The authors illustrate the potential role of psychology – in particular, illustrative theories and research – in achieving two SDGs: SDG 1 (reduce poverty) and SDG 5 (achieve gender equality and empowerment). We selectively consider life span (individual) developmental and life course (environmental structure) theories as useful for explaining how poverty and inequality influence the individual and community at individual points in time and over time. Further, we use both the theoretical approach outlined in the convoy model of social relations as well as multinational empirical evidence to illustrate how naturally occurring resources can be garnered to better explain, understand, identify, and create successful intervention programs. We emphasize that psychology is fundamental to achieving SDGs and that we should focus on how to change the behavior and expectations of individuals and societies to achieve sustainable development that contributes to a world that celebrates optimal and sustainable development for all.

Published: June 2019

Abstract. Youth-led early childhood care and education (ECCE) programs offer a promising model for achieving multiple Sustainable Development Goal targets. The program “Youth Leaders for Early Childhood Assuring Children are Prepared for School” (LEAPS) was developed to address the educational needs of children and female youth in rural Sindh, Pakistan. In LEAPS, community youth leaders (CYLs), aged 18–24 years, implement an ECCE program after receiving targeted, practical training and engaging in continuous mentoring and communities of practice. This paper focuses on the experience of LEAPS participation for ten CYLs. Using random intercept generalized linear latent and mixed models, significant improvements were observed in ECCE and professional skills. Quantitative analyses were triangulated with results from a qualitative analysis of two CYL exit focus group discussions. Findings suggest that, in some contexts, youth-led ECCE models can feasibly address ECCE workforce gaps while offering leadership and professional development opportunities for youth.

Published: June 2019

Abstract. Economic changes in the context of globalization have left adolescents from Latin American contexts with few opportunities to make satisfactory transitions into adulthood. Recent studies indicate that there is a protracted period between the end of schooling and entering into formal working activities. While in this “limbo,” illicit activities, such as drug trafficking may emerge as an alternative for young people to ensure their social participation. This article aims to deepen the understanding of Brazilian youth’s involvement in drug trafficking and its intersection with their schooling, work, and aspirations, connecting with Sustainable Development Goals (SDGs) 4 and 16 as proposed in the 2030 Agenda for Sustainable Development adopted by the United Nations in 2015 .

Published: June 2019

Human activities interacting with coastal waters lead to large amounts of nutrient loading and severe water pollution in China's near Seas. In this context, a comprehensive quantitative characterization of the spatiotemporal variation of nutrient pollutant concentrations is a key component of any reliable seawater quality assessment and integrated coastal management plan. The present work combines the Bayesian maximum entropy method with stochastic site indicators to estimate monthly nitrate and phosphate concentrations in China's near seas during 2015, explore their spatiotemporal variation, and provide an explicit quantitative assessment of seawater quality in conditions of in situ uncertainty. This makes it the first study of space‐time nutrient pollutant characterization at a national‐scale in a coastal seawater environment. The results showed that nitrate and phosphate distributions exhibit the same spatial trends along China's near seas, whereas high nutrient pollution levels are found in the Yangtze River, Liaohe River, and Pearl River estuaries. Local differences of temporal trends exist between nitrate and phosphate distributions, which suggest that distinct remediation strategies are needed to properly satisfy the required seawater quality standards. The average nitrate and phosphate concentrations across space‐time were found to be equal to 0.271 and 0.015 mg/L, respectively. The nitrate and phosphate concentrations exceeding the fourth grade seawater quality standard during 2015 were about 11% and 2.6%, respectively. The study of both the seasonal changes in human activities along the coastal cities and the temporal marine hydrodynamics can offer a better understanding of the seawater quality and the biogeochemical process of nutrient transport and distribution.
Statistics of chromatin organization during cell differentiation revealed by heterogeneous cross-linked polymers
Authors: Shukron O. , Piras V. , Noordermeer D. , Holcman D.
Published: June 2019

Chromatin of mammalian nucleus folds into discrete contact enriched regions such as Topologically Associating Domains (TADs). Folding hierarchy and internal organization of TADs is highly dynamic throughout cellular differentiation, and are correlated with gene activation and silencing. To account for multiple interacting TADs, we developed a parsimonious randomly cross-linked (RCL) polymer model that maps high frequency Hi-C encounters within and between TADs into direct loci interactions using cross-links at a given base-pair resolution. We reconstruct three TADs of the mammalian X chromosome for three stages of differentiation. We compute the radius of gyration of TADs and the encounter probability between genomic segments. We found 1) a synchronous compaction and decompaction of TADs throughout differentiation and 2) high order organization into meta-TADs resulting from weak inter-TAD interactions. Finally, the present framework allows to infer transient properties of the chromatin from steady-state statistics embedded in the Hi-C/5C data.

Multidrug efflux pumps actively expel a wide range of toxic substrates from the cell and play a major role in intrinsic and acquired drug resistance. In Gram-negative bacteria, these pumps form tripartite assemblies that span the cell envelope. However, the in situ structure and assembly mechanism of multidrug efflux pumps remain unknown. Here we report the in situ structure of the Escherichia coli AcrAB-TolC multidrug efflux pump obtained by electron cryo-tomography and subtomogram averaging. The fully assembled efflux pump is observed in a closed state under conditions of antibiotic challenge and in an open state in the presence of AcrB inhibitor. We also observe intermediate AcrAB complexes without TolC and discover that AcrA contacts the peptidoglycan layer of the periplasm. Our data point to a sequential assembly process in living bacteria, beginning with formation of the AcrAB subcomplex and suggest domains to target with efflux pump inhibitors.

Published: June 2019

Polaritons are widely investigated quasiparticles with fundamental and technological significance due to their unique properties. They have been studied most extensively in semiconductors when photons interact with various elementary excitations. However, other strongly coupled excitations demonstrate similar dynamics. Specifically, when magnon and phonon modes are coupled, a hybridized magnon–phonon quasiparticle can form. Here, we report on the direct observation of coupled magnon–phonon dynamics within a single thin nickel nanomagnet. We develop an analytic description to model the dynamics in two dimensions, enabling us to isolate the parameters influencing the frequency splitting. Furthermore, we demonstrate tuning of the magnon–phonon interaction into the strong coupling regime via the orientation of the applied magnetic field.

The brain stores and recalls memories through a set of neurons, termed engram cells. However, it is unclear how these cells are organized to constitute a corresponding memory trace. We established a unique imaging system that combines Ca2+ imaging and engram identification to extract the characteristics of engram activity by visualizing and discriminating between engram and non-engram cells. Here, we show that engram cells detected in the hippocampus display higher repetitive activity than non-engram cells during novel context learning. The total activity pattern of the engram cells during learning is stable across post-learning memory processing. Within a single engram population, we detected several sub-ensembles composed of neurons collectively activated during learning. Some sub-ensembles preferentially reappear during post-learning sleep, and these replayed sub-ensembles are more likely to be reactivated during retrieval. These results indicate that sub-ensembles represent distinct pieces of information, which are then orchestrated to constitute an entire memory.

Published: June 2019

Flexible electronics is one of the fundamental technologies for the development of electronic skin, implant wearables, or ubiquitous biosensing. In this context, graphene-derived materials have attracted great interest due to their unique properties to fulfill the demands of these applications. Here we report a simple one-step method for the fabrication of electrophysical electrodes based on the photothermal production of porous nanographene structures on the surface of flexible polyimide substrates. This approach constitutes an inexpensive alternative to the commercial medical electrodes, leading to a lower and much more stable skin–electrode contact resistance and providing comparable signal transduction. This technology has been framed inside the IoT paradigm through the development of a denoising and signal classification clustering algorithm suitable for its implementation in wearable devices. The experiments have shown promising achievements regarding noise reduction, increasing the crest factor ~3.7 dB, as well as for the over 90% heart rate-monitoring accuracy.
What we learned from creating one of the world’s most popular MOOCs
Authors: Oakley Barbara A. , Sejnowski Terrence J.
Published: June 2019

Learning How to Learn (LHTL) is currently one of the world’s most popular massive open online course (MOOC), with nearly 2.5 million registered learners in its first 4 years. Here, we “reverse engineer” the design of the course’s videos to show how creative application of well-known principles of multimedia learning in an MOOC context appear to have fueled the course’s popularity. Gaps in knowledge of multimedia learning are also noted. There have been some 50 years of experience researching effective classroom teaching, but less there have been only 5 years since MOOCs became widespread. The success of LHTL may provide further insight into the importance of the principles of multimedia learning, and how those principles might be practically implemented to improve MOOC making and the general design of instructional videos.
Combinatorial perturbation analysis reveals divergent regulations of mesenchymal genes during epithelial-to-mesenchymal transition
Authors: Watanabe Kazuhide , Panchy Nicholas , Noguchi Shuhei , Suzuki Harukazu , Hong Tian
Published: June 2019

Epithelial-to-mesenchymal transition (EMT), a fundamental transdifferentiation process in development, produces diverse phenotypes in different physiological or pathological conditions. Many genes involved in EMT have been identified to date, but mechanisms contributing to the phenotypic diversity and those governing the coupling between the dynamics of epithelial (E) genes and that of the mesenchymal (M) genes are unclear. In this study, we employed combinatorial perturbations to mammary epithelial cells to induce a series of EMT phenotypes by manipulating two essential EMT-inducing elements, namely TGF-β and ZEB1. By measuring transcriptional changes in more than 700 E-genes and M-genes, we discovered that the M-genes exhibit a significant diversity in their dependency to these regulatory elements and identified three groups of M-genes that are controlled by different regulatory circuits. Notably, functional differences were detected among the M-gene clusters in motility regulation and in survival of breast cancer patients. We computationally predicted and experimentally confirmed that the reciprocity and reversibility of EMT are jointly regulated by ZEB1. Our integrative analysis reveals the key roles of ZEB1 in coordinating the dynamics of a large number of genes during EMT, and it provides new insights into the mechanisms for the diversity of EMT phenotypes.

Assemblage structure of ichthyoplankton in the NE Atlantic in spring under contrasting hydrographic conditions
Authors: Rodriguez J. M.
Published: June 2019

The ichthyoplankton assemblage in the Atlantic region off the NW Iberian peninsula (AR) and in the southern Bay of Biscay (SBB) and the response of the larval fish species distribution to the relatively rapidly changing hydrographic conditions in spring 2010 were studied using two ichthyoplankton cruises. The SBB showed a more abundant and diverse ichthyoplankton assemblage than the AR, although the larval fish assemblage (LFA) was structured into on-shelf and off-shelf assemblages in both regions. Inter-sampling variability related to downwelling/upwelling regimes was observed in the cross-shelf assemblage distribution in the SBB but not in the AR. This suggests that LFA distributions in the area of this study are good indicators of downwelling and weak coastal upwelling regimes but not of relatively strong coastal upwelling or upwelling filaments. Although depth was identified by multivariate analyses as being the most important variable explaining larval fish species distributions, a shelf-breakfront in the SBB and the surface offshore (onshore) flows associated with coastal downwelling (upwelling) in the AR seems to have been key in defining and maintaining assemblage boundaries. Results of this study should also encourage marine research institutions to use routine ichthyoplankton sampling to monitor fish communities and their responses to global warming.

Sesamin is a furofuran-type lignan that is found abundantly in seeds of Sesamum indicum (sesame) and has been widely accepted as a dietary supplement with positive effects on human health. The biological activity of sesamin in human cells and organs has been analysed extensively, although comparatively few studies show biological functions for sesamin in planta. Herein we screened sesamin-binding proteins (SBP) from sesame seedling extracts using sesamin-immobilized nano-beads. In subsequent peptide mass fingerprinting analyses, we identified a SBP, Steroleosin B, which is one of the membrane proteins found in oil bodies. In addition, pull-down assays and saturation transfer difference-nuclear magnetic resonance (STD-NMR) experiments demonstrated that sesamin binds directly to recombinant Steroleosin B in vitro. Finally, ectopic accumulations of sesamin and Steroleosin B in transgenic Arabidopsis thaliana plants induced severe growth defects including suppression of leaf expansion and root elongation. Collectively, these results indicate that sesamin influences tissue development in the presence of Steroleosin B.
Strengthen of magnetic anisotropy of Au/Co/Au nanostructure by surface plasmon resonance
Authors: Kikuchi Yusuke , Tanaka Takuo
Published: June 2019

We experimentally demonstrated the increase of in-plane magnetic anisotropy in Au/Co/Au nanostructures by localized surface plasmon resonance (LSPR). When an array of Au/Co/Au square patch nanostructures was illuminated with linearly polarized light whose wavelength was 750 nm, the localized surface plasmons were resonantly excited in the nanostructures. From the measurement results of polar magneto-optical Kerr effect curves, we observed the magnetic anisotropy field increase in the Au/Co/Au nanostructure due to the excited surface plasmons. The in-plane magnetic anisotropy energy density was increased about 24%.
miR-29c overexpression and COL4A1 downregulation in infertile human endometrium reduces endometrial epithelial cell adhesive capacity in vitro implying roles in receptivity
Authors: Griffiths Meaghan , Van Sinderen Michelle , Rainczuk Katarzyna , Dimitriadis Evdokia
Published: June 2019

The endometrium is a highly complex tissue that is vulnerable to subtle gene expression changes and is the first point of contact for an implanting blastocyst. Successful blastocyst implantation can only occur when the endometrium is receptive during a short window with each menstrual cycle. microRNAs are small, non-coding RNAs that negatively regulate their gene targets. miR-29c has previously been identified to be differentially regulated across the fertile menstrual cycle, however it has not been investigated in association with infertility. We hypothesised that miR-29c dysregulation in the infertile endometrium would negatively influence endometrial adhesion and blastocyst implantation outcomes during the mid-secretory, receptive phase. miR-29c expression was elevated in early and mid-secretory phase infertile endometrium and localised to the epithelial compartments of endometrial tissue. Overexpression of miR-29c in vitro impaired endometrial epithelial adhesion, and reduced collagen type IV alpha 1 (COL4A1) mRNA expression. COL4A1 was immunolocalised to the luminal and glandular epithelial basement membranes in early and mid-secretory phase fertile and infertile endometrium for the first time. Knockdown of COL4A1 impaired endometrial epithelial adhesion suggesting a role in endometrial receptivity and implantation. Our data suggests miR-29c overexpression with infertility may impair the adhesive capacity of the endometrium, potentially contributing to implantation failure and infertility.

Published: June 2019

To compare two broadly used 4D-flow- with a 2D-flow-sequence in healthy volunteers, regarding absolute flow parameters, image quality (IQ), and eddy current correction (ECC). Forty volunteers (42 ± 11.8 years, 22 females) were examined with a 3T scanner. Thoracic aortic flow was assessed using a 3D-T2w-SPACE-STIR-sequence for morphology and two accelerated 4D-flow sequences for comparison, one with k-t undersampling and one with standard GRAPPA parallel-imaging. 2D-flow was used as reference standard. The custom-made software tool Bloodline enabled flow measurements for all analyses at the same location. Quantitative flow analyses were performed with and without ECC. One reader assessed pathline IQ (IQ-PATH) and occurrence of motion artefacts (IQ-ART) on a 3-point grading scale, the higher the better. k-t GRAPPA allowed a significant mean scan time reduction of 46% (17:56 ± 5:26 min vs. 10:40 ± 3:15 min) and provided significantly fewer motion artefacts than standard GRAPPA (IQ-ART 1.57 ± 0.55 vs. 0.84 ± 0.48; p < 0.001). Neither 4D-flow sequence significantly differed in flow volume nor peak velocity results with or without ECC. Nevertheless, the correlation between both 4D-flow sequences and 2D-flow was better with ECC; the k-t GRAPPA sequence performed best (R = 0.96 vs. 0.90). k-t GRAPPA 4D-flow was not inferior to a standard GRAPPA-sequence, showed fewer artefacts, comparable IQ and was almost two-fold faster.
Strong charge polarization effect enabled by surface oxidized titanium nitride for lithium-sulfur batteries

Published: June 2019

The commercialization of high-energy-density and low-cost lithium-sulfur batteries has been severely impeded by capacity fading and electrochemical polarization. Here we report a strategy to entrap polysulfides and boost the cathodic redox kinetics by embedding the surface oxidized quantum-dot-size TiN (TiN-O) within the highly ordered mesoporous carbon matrix. While the carbon scaffold offers sufficient electrical contact to the insulate sulfur, benefiting the full usage of sulfur and physical confinement of polysulfides. The surface oxygen renders TiN-O with a strong charge polarization effect for polysulfides via S-O-Ti bond as verified experimentally and theoretically. The suppressed shuttle effect and high lithium ion diffusion coefficient (7.9 × 10−8 cm2 s−1) lead to a high capacity of 1264 mA h g−1 at 0.2 C with a negligible capacity fading rate of 0.06% per cycle. Additionally, TiN-O based prototype soft-package cells also exhibit excellent cycling stability with flexibility, demonstrating their potential for practical applications.
A sustainable mesoporous palladium-alumina catalyst for efficient hydrogen release from N-heterocyclic liquid organic hydrogen carriers
Authors: Oh Jinho , Bathula Hari Babu , Park Ji Hoon , Suh Young-Woong
Published: June 2019

Liquid organic hydrogen carriers (LOHC) are interesting hydrogen vectors which can exploit existing infrastructure. Specifically, N-heterocyclic compounds are attractive due to lower dehydrogenation enthalpy than homocyclic ones and demand a viable palladium catalyst to guarantee high dehydrogenation activity at low temperatures and stability in recycle runs. Here, we employ one-pot solvent deficient precipitation yielding a mesoporous palladium-alumina. The prepared catalyst system offers higher hydrogen release capability by 20% than conventional palladium/γ-Al2O3 in the dehydrogenation of four different N-heterocyclic compounds at or below 250 °C. Futhermore, it shows negligible activity loss up to five consecutive runs for perhydro 2-(n-methylbenzyl)pyridine and perhydro 2-methylindole. Such dehydrogenation performance is caused by the solvent deficient environment that restricts palladium mobility by contiguous alumina particles and produces well-dispersed palladium phase with a higher density of (111) plane. Therefore, the reported synthesis method may contribute to the production of innovative dehydrogenation catalysts for LOHC compounds.

Word-Final Repetition in an Adult With Attention-Deficit/Hyperactivity Disorder: A Case Report
Authors: Evans David L. , Owens K. Leann
Published: June 2019

Purpose

The purpose of this report was to describe the nature of word-final repetition (WFR) in an adult with normal intelligence and attention-deficit/hyperactivity disorder.

Method

A 25-year-old man completed speaking tasks that differed in linguistic complexity to examine the nature of his WFRs and the effect a stimulant medication had on his frequency of WFR.

Results

WFR occurred as a single iteration on sentences containing 2 or more clauses and occurred most often during monologue speaking tasks, on the final complete syllable of multisyllabic words, on content words, and on words in the utterance-final position. A minimal increase in WFR occurred when the participant completed a speaking task with a stimulant medication than the same speaking task without a stimulant medication.

Conclusion

Findings are similar to previous cases of WFR among school-age children, which have reported the majority of WFRs during propositional speaking tasks and a limited awareness of WFR. Linguistic, motor, coexisting conditions, and genetic explanations of WFR are considered relative to this case. Intervention of WFR should consider the individual needs of the client and the client's awareness of WFR.
Electrical Energy Demand in Rural India - A Case Study of Arunachal Pradesh and Uttar Pradesh
Authors: Seppälä Anna-Kaarina , Gaihre Nabin Raj , Pereira Rinald
Published: June 2019

India currently has the biggest unelectrified population in the world. Renewable-based microgrids could provide a sustainable solution to providing universal energy access. However, the potential electricity demand in rural areas is unknown and hard to predict. This data is needed to analyse the purchasing power and potential market for microgrids, and to assess their success rate. This study surveyed 73 households in Arunachal Pradesh and Uttar Pradesh in India, to study the energy need in rural communities. The data shows that many unelectrified households are already using electrical appliances powered by small photovoltaic panels or batteries. The consumption is not income-generating but potential productive use cases are widely present. In Uttar Pradesh, small-scale microgrids are already providing homes with enough power for lighting and mobile chargers. An average unelectrified household was found to consume 2.48 kWhe monthly, and to spend ₹ 155 on energy services. Villagers wish for more appliances and more power, and have the required finances to pay for it.

The temporal and spatial prediction of nitrogen dioxide (NO2) is very essential because of its harmful impacts on the environment. Its forecasting would help, for example, to regulate predictively the traffic flow. Traditionally, air quality measurements are performed at fixed locations or dedicated mobile laboratories. In this work, we installed a measurement technology in a vehicle and connected it to the vehicle measuring system in order to be able to evaluate further parameters. To this end, we selected one route profile and continuously measured the NO2concentration in real-time traffic. We have driven this route profile several times in succession. The rationale of this approach is the idea that several vehicles are equipped with the same measurement technology and drive on the same route profile within the same time. The contribution of this work is to forecast the NO2concentration for a given route profile under constant weather conditions based on mobile measurements. To this end, we divided the recorded data into training and test data and investigated five different approaches for forecasting the NO2concentration on the respective route profile. Among other aspects, we used cross-validation methods in order to assess the prediction quality. Results show that sliding-window approaches using the averaging of previous rounds are most suitable for predicting NO2concentration. Furthermore, our data reveal that the prediction quality is improved when the test data immediately follow the training data.
Study of Monsoonal Features Using Regional Climate Model over Heterogeneous Monsoon Dominated Region
Authors: Srivastava Rohit , Shah Ruchita
Published: June 2019

Global warming is an increase in average global temperature of the earth which lead to climate change. Heterogeneity in the earth-atmosphere system becomes difficult to capture at low resolution (1°x1°) by satellite. Such features may be captured by using high resolution model such as regional climate model (0.5°x 0.5°). This type of study is quite important for a monsoon dominated country like India where Indo-Gangetic Plains (IGP) faces highest heterogeneity due to its geographic location. Present study compares high resolution model features with satellite data over IGP for monsoon season during a normal rainfall year 2010 to understand the actual performance of model. Almost whole IGP simulates relative humidity (RH) with wide range (~50-100%), whereas satellite shows it with narrow range (~60-80%) during September, 2010. Thus model is able to pick the features which were missed by satellite. Hence further model simulation extends over India and adjoining oceanic regions which simulates data of southwest monsoon with high (~70-100%) RH, high (~0.4-0.7) cloud fraction (CF) and low (~80-200 W/m2) outgoing longwave radiation (OLR) over Arabian Sea during June, 2010. Such type of study can be useful to understand heterogeneity at regional scale with the help of high resolution model generated data.

Cigu wetland consists of industrial salt ponds and lagoon is situated at the coast in the southwestern of Taiwan which is demarcated as Coastal Nature Reserve. The salt ponds experienced declines in bird species diversity and population compared with those within the lagoon area due to the deeper water depths. Different kinds of measures to alter water depths of salt ponds by filling soil are proposed. The hydrodynamic simulations were conducted for studying the hydrodynamic response to proposed reconstruction alternatives. The potential waterbird abundance was then estimated for the alternative recommendation. The methodology proposed in this study can reduce the risk of unexpected results by implementing the reconstruction project directly.

Aviation, as every type of transport, is responsible for a number of negative external effects to the environment. The main goal of this study is to reveal the relation between the noise level in the urban areas near to the Burgas airport and the air traffic. Our main research tasks are: to make a literature review of the problem; to gather data for the noise levels; to gather data for the air traffic; to choose relevant statistical methods and models for the revealing of the relation between the noise level and air traffic; to draw conclusions and to make recommendations about the noise pollution in the vicinity of Burgas Airport. The data are on monthly basis and cover the period from January 2015 to December 2017, i.e. 36 months. In our regression model we use three traffic indicators as independent variables: aircraft movements; passengers and freight. In the established regression model we introduce ‘the time’ as an additional factor, which provides concrete practical advantages. Our results show that two independent variables (aircraft movements and freight) affect the Twenty-four hours average equivalent level of noise due to flights. Aircraft movements are the most important factor and we expect their increasing in the future. This will lead to increased noise levels.

Environmental Education is the key for creating a clean energy future for not only the nation, but the world. World Energy Consumption relies heavily on coal, oil, and natural gas. Fossil fuels are non-renewable, that is, they rely on finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve. In contrast, renewable energy resources, such as wind and solar energy, are constantly replenished and will never run out. Due to the rising need for professionals and academics with a background and understanding in the Energy field, Holon Institute of Technology (HIT) developed an integral system of environmental education and training and a new program at the Faculty of Electrical Engineering. The Renewable Energy program gives the students technical and practical aspects of energy use (technology and methodology of the study) and energy efficiency. The program also deals with minimizing the environmental impacts of energy use, as well as with energy economy and environmental policy. This article presents a new challenge. Teach environmental issues with language difficulties. Israeli Hebrew speaker students, teach environmental education in Arab school with Arabic speaker pupils’.
Problem of conjugate heat transfer between main gas pipeline and frozen ground
Authors: Bondarev Edward , Rozhin Igor , Argunova Kira
Published: June 2019

Mathematical model of non-isothermal gas flow within the framework of tube hydraulics including change of tube cross-section due to hydrate formation and the dependence of coefficient of heat transfer between gas and hydrate layer on varying flow area is proposed. The corresponding conjugate problem of heat exchange between imperfect gas in the pipeline and the environment is reduced to the solution of differential equations describing non-isothermal flow of gas in pipes and heat transfer equations in ground with the corresponding conjugation conditions. In the quasi-stationary mathematical model of hydrate formation (dissociation), the dependence of gas-hydrate transition temperature on gas pressure is taken into account. Some decisions taken in the design of the first section of the main gas pipeline «Power of Siberia» have been analyzed. It has been shown that if gas is not sufficiently dried, outlet pressure may drop below the technological limit in about 6-7 hours. At the same time, for completely dry gas ,it is possible to reduce the cost of thermal insulation of the pipeline at least two fold.

The current algorithm for calculating mass flow rate in gas production and transportation systems via outlet pressure measurements is generalized to the case when the inner cross section of pipe changes with time and is also to be determined while solving the general problem. The algorithm is recommended for identification of gas hydrate formation in the above-mentioned systems.
Existence, uniqueness and monotonic behavior of the solution of classical flow distribution problem for hydraulic networks with pressure-dependent closure relations
Authors: Korelstein Leonid
Published: June 2019

Existence, uniqueness and monotonic behavior of the solution of classical flow distribution problem for hydraulic networks with pressure-dependent closure relations was proved. The closure relation can have very general form, restricted only by continuity and monotonicity conditions necessary for providing existence, uniqueness and continuity of flow distribution problem for each branch. It is shown that network as a whole “inherits” monotonicity and continuity of its branches behavior, and this provides existence and uniqueness of solution.

Published: June 2019

An alternative to conventional Cu(In,Ga)Se2 module structure is proposed and experimentally investigated. This alternative module structure, which consists in applying metallic buses to connect monolithically adjacent cells in series, is likely to offer the opportunity of minimizing both optical and electrical losses observed in conventional module structure compared to small area cells. The fabrication process of such alternative modules is presented. The performances achieved are discussed in comparison with a standard small-area-cell elaborated simultaneously. Despite slightly lower output voltage per cell, the alternative module structure demonstrates an efficiency of 17.2% (with 81% fill factor), against 16.4% (with 75% fill factor) for the standard cell. This promising result opens new routes to decrease the gap observed between small-area-cells and industrial modules.
Do high emotional intelligent soccer referees better cope with competitive stressors?
Authors: Louvet Benoît , Campo Mickaël
Published: June 2019

Refereeing in sport is a particularly stressful task that requires coping effectively with interpersonal pressures. Emotional intelligence could participate to promote soccer referees’ better adjustment. The relations between emotional intelligence and coping could also discriminate soccer referees according to their level of expertise. Thus, the aim of this study is to explore the influences of emotional intelligence among soccer officials, by analyzing the relations between emotional intelligence, the level of expertise level, and the use of coping strategies. Two studies were conducted in which 116 and 75 soccer referees participated. They completed two inventories related to emotional intelligence and coping. Results indicated the presence of two profiles of emotional intelligence. In comparison to the moderate emotional intelligence cluster, most of the high-skilled referees belonged to the moderately high emotional intelligence profile. Furthermore, the dimensions of emotional intelligence predicted significantly and positively the use of task-oriented coping. These results provide a new contribution to the literature in sport psychology on emotional intelligence and coping and propose further perspectives for sport officials’ psychological preparation.
