ObjectivesDespite the potential link between mental skills and athletic performance, little is done to examine handball players’ present level of mental skills concerning their performance. To begin with, the study has three folded aims; the first one is to examine the factor structure of Bull’s Mental Skills Questionnaire, which was developed in the United Kingdom to measure selected mental skill, of Serbian athlete population. The second aim is to determine gender differences in those mental skills, and the third aim is to determine differences between the playing positions in the mental skills of handball players to create a mental profile of Serbian handball players.Materials and methodsThe sample consisted of 170 handball players, aged 14 to 39, who have played handball at the semi-elite, competitive-elite, and successful-elite level. The modified exploratory factor analysis was used to determine the latent dimensions of the Bull’s Mental Skills Questionnaire. For examining gender differences in the manifestation of mental skills Mann–Whitney U test was used.ResultsCompared to the original structure of the questionnaire, which singles out seven factors of mental skills (imagery ability, mental preparation, self-confidence, anxiety and worry management, concentration ability, relaxation ability, and motivation), five factors were singled out in the sample of Serbian male and female handball players (anxiety and concentration management—α = 0.74; self-confidence—α = 0.75; relaxation ability—α = 0.66; mental preparation—α = 0.68, and imagery ability—α = 0.66). With these five subscales as dependent variables, results of the Mann–Whitney U test show that there are significant gender differences in variable anxiety and concentration management (U = 2893.5, p = 0.049) and relaxation ability (U = 2833.0, p = 0.031). Female handball players score higher on anxiety and concentration management and lower on relaxation ability. When playing positions are in question, results of Kruskal–Wallis‘s one-way analysis of variance, i.e., Mann–Whitney’s post hoc analysis, suggest that statistically significant differences were observed between wings and center backs and wings and goalkeepers in the imagery ability.ConclusionThe Bull’s Mental Skills Questionnaire in Serbian sample of handball players show satisfactory psychometric characteristics but has singled out five factors of mental skills compared to the original questionnaire.

Authors: Pitros Christos , Mansi Pietro , Kakkos Stavros 
Published: August 2022

BackgroundEndovascular aortic repair (EVAR) of abdominal aortic aneurysms (AAAs) has emerged as a better alternative to conventional open surgery for AAAs. The purpose of the review is to define the improvement in the clinical management of the patient with hostile neck AAAs due to the introduction of new endografts while giving a thorough description of their instructions for use (IFUs), main characteristics and part sizing, reporting their outcomes from clinical studies and categorizing their usability.MethodsA MEDLINE search was conducted using keyword-specific combinations. Clinical studies were searched via the clinicaltrials.gov website. Relevant articles' references were also hand-searched.ResultsWe retrieved 640 records describing Alto, Ovation iX, Treovance, Aorfix, Anaconda, Conformable, and Endurant II/IIs endografts. Aortic necks &gt;60° can be managed with Anaconda, Aorfix, and Conformable, which can treat up to 90° necks requiring ≥15 mm (Anaconda ≥20 mm), and Treovance, which is eligible for necks ≤75° with ≥15 mm length. Ovation's innovation of combining polymer-filled O-rings with integral anchors can treat conical necked AAAs giving Ovation iX and Alto an advantage. Short-necked AAAs can be treated with Alto, eligible for necks as short as 7 mm, and Endurant II, which can treat ≥10 mm necks or 4 mm if used in conjunction with the EndoAnchors system, respectively. Alto and Conformable report a 100% technical success rate, absence of AAA-related death, migration, ruptures, and limb occlusion during follow-up. Endurant II and Ovation iX report &gt;99% technical success rate and are almost free from the AAA mortality rate, ruptures, migration, and limb occlusion, while Ovation iX has a high rate of sac dilation (15.5%) in a 5-year follow-up. Anaconda is slightly better than Aorfix and Treovance, which are related to the lowest technical success rates, 98.3%, 96.3%, and 96%, respectively. Aorfix has the highest AAA mortality rate, 4% in a 60 month follow-up.ConclusionMost new generation endografts described have comparable results. They broaden the eligibility of patients for EVAR due to their unique technical characteristics described. There is a lack of comparative studies for newer endografts and postmarket clinical studies with long-term results concerning the most recently approved devices described, Alto and Conformable.

Published: August 2022

This work presents a complete review of the literature on and a critical evaluation and thermodynamic optimization of the Li-Se and Na-Se binary systems. The modified quasi-chemical model in the pair approximation (MQMPA) was employed to describe the liquid solution exhibiting a high degree of short-range ordering behavior of atoms. The thermodynamic properties of the compounds Li2Se (cF12_Fm3¯m), Na2Se (cF12_Fm3¯m), NaSe (hP8_P63/mmc), and NaSe2 (tI48_I4¯2d) were also calculated by using first-principles density functional theory (DFT) calculations to assist the thermodynamic description of these two binary systems. All the available and reliable experimental data are reproduced within experimental error limits. Moreover, the phase equilibria of these two systems at low total pressure were analyzed by using the developed thermodynamic model.

Photocurrent diffusion of organic photodetector between pixels for fingerprint sensor by using interdigitated electrodes
Authors: Misran Muhamad Affiq Bin , Khan Rauf , Bilgaiyan Anubha , Hattori Reiji 
Published: August 2022

Abstract
The organic photodetectors (OPDs) with an interdigitated electrodes structure are analyzed to evaluate the optical crosstalk between neighboring pixels for the organic image sensor used in the fingerprint-on-display authentication system. The shorter exciton diffusion length of organic semiconductors in the OPD can promote the high resolution of the organic image sensor for full-display sensing applications. We demonstrated the photocurrent diffusion from the exposed area to the hidden electrodes by changing the distance to predict the minimum pixel pitch for the organic image sensor. Unexpectedly, the photocurrent diffusion was observed, even at 10 μm length, as more significant than the expected exciton diffusion length.

Published: August 2022

Abstract
GaN layers are grown on 2 inch ScAlMgO4 (0001) nominally on-axis substrates by metalorganic vapor phase epitaxy. The epilayer structural qualities are comparable to those of conventional GaN on sapphire (0001) substrates. The wafer curvature is investigated using X-ray diffraction, and the results suggest suppressed bowing in the GaN/ScAlMgO4 heterostructures compared with the GaN/sapphire heterostructures. This result is attributed to a smaller mismatch of the thermal expansion coefficients in GaN/ScAlMgO4. The suppressed bowing can be beneficial for device processes.

Aim. The presented study aims to develop a scientifically based method of obtaining quantitative indicators for the staffing of priority areas through the training of highly qualified scientific personnel. Tasks. The authors create a methodology for comparing the topics of dissertation research (scientific specialties and dissertation topics) with the priority areas formulated in the Strategy for the Scientific and Technological Development of the Russian Federation (STD RF); conduct a survey of candidates of sciences to learn their assessment of the compliance ofdissertation research topics with the priority areas of the STD RF strategy and to identify the peculiarities of the professional development of candidates of sciences after the defense of their dissertations; analyze the staffing of the priority areas of the STD RF strategy through the training of highly qualified personnel (HQP) based on the results of the survey and the developed methodology for matching the topic of the dissertation with the topics of the priority areas of the STD RF strategy and the retention of the trained HQP in the scientific and technological field corresponding to such priority areas; identify Competence Centers for the training of HQP for the staffing of the priority directions of the STD RF strategy. Methods. A methodology of step-by-step matching of dissertation research and priority areas according to the criteria of "scientific specialty" and "dissertation title" is developed using three approaches: expert, keyword-based, and embedding-based. A sociological survey of 8,402 candidates of sciences was conducted to obtain quantitative indicators. Results. It is found that only one out of three candidates of sciences who defended a dissertation in one of the priority areas continues to engage in scientific activity on the subject of his dissertation after the defense. Over half of the candidates of sciences (around 60 %) whose dissertation topic corresponds to the priorities of the STD RF strategy occasionally engage in scientific activities on the subject of their dissertation research. Around 12 % of candidates of sciences stopped developing their research topics after defending their dissertations. Conclusions. The potential of HQP trained in the subject of priority areas is not fully realized. The number of HQP that remain focused on the topics of the priority areas of the STD RF strategy can serve as a benchmark for the formation of indicators of staffing efficiency in the priority areas of scientific and technological development.

Frente à pior pandemia do último século, a estratégia viável para os sistemas de ensino foi realizar atividades educacionais por aplicativos e plataformas que facilitem a comunicação entre a escola e estudantes. Diante deste cenário, a presente pesquisa qualitativa objetivou analisar as percepções dos professores, das redes estaduais de Mato Grosso e do Rio Grande do Sul, nos municípios de Querência e Arroio do Sal respectivamente, em relação ao ensino remoto e as tecnologias digitais. Foi realizada entre no mês de novembro de 2020, por meio de formulário eletrônico encaminhado para unidades escolares de Querência e de Arroio do Sal. Foram 82 respondentes que consentiram e responderam na íntegra ao solicitado. Como maiores dificuldades encontradas pelos professores com o retorno às aulas, sobrecarga de trabalho – 93,80% para Querência e 82,40% para Arroio do Sal – a falta de acesso e de conhecimento por parte dos estudantes – 79,30% em Querência e 73,30% em Arroio do Sal. Todavia, o que se pode constatar é que a falta de formação foi maior em Querência – 41,70% – reflexo da não atenção devida pela Secretaria Estadual de Educação de Mato Grosso, que se soma a falta de conhecimento sobre as Tecnologias Digitais da Informação e Comunicação (TDICs).

Published: August 2022

El presente ensayo argumenta y recoge el pensamiento y sentir existencial que alrededor de la figura del docente universitario se explaya desde La educación, como un agente motivador y un propulsor de los cambios sociales, donde la praxis del docente universitario, posee la capacidad de transformar su entorno, enriqueciendo la condición humana de sus estudiantes, porque dicha labor, es mucho más compleja que cualquier otra actividad profesional, pues implica el desarrollar y formar el carácter, la inteligencia y la personalidad de los estudiantes, que serán los futuros profesionales del país. El docente universitario trae consigo un mundo de valores, ser docente ayer, hoy y en el futuro ha sido, es y será una enorme responsabilidad la que, a la vez, se constituye en un privilegio singular que todos los que ejercemos la docencia conocemos. La posibilidad de contribuir a la formación de personas es, sin duda, una tarea ardua y, por qué no decirlo, envidiable, que hoy tiene posibilidades reales de tener alcance global. El que escoge la profesión docente, comienza un camino que está profundamente marcado por el fin último y primera prioridad que incluye su práctica: que los estudiantes aprendan y se desarrollen. Esa prioridad involucra una responsabilidad enorme, y requiere de personas que tengan grandes capacidades.

Probing Magnetic Fields in Protoplanetary Disk Atmospheres through Polarized Near-IR Light Scattered by Aligned Grains
Authors: Yang 杨 Haifeng 海峰 , Li Zhi-Yun 
Published: August 2022

Abstract
Magnetic fields play essential roles in protoplanetary disks. Magnetic fields in the disk atmosphere are of particular interest, as they are connected to the wind-launching mechanism. In this work, we study the polarization of the light scattered off of magnetically aligned grains in the disk atmosphere, focusing on the deviation of the polarization orientation from the canonical azimuthal direction, which may be detectable in near-IR polarimetry with instruments such as VLT/SPHERE. We show with a simple disk model that the polarization can even be oriented along the radial (rather than azimuthal) direction, especially in highly inclined disks with toroidally dominated magnetic fields. This polarization reversal is caused by the anisotropy in the polarizability of aligned grains and is thus a telltale sign of such grains. We show that the near-IR light is scattered mostly by μm-sized grains or smaller at the τ = 1 surface and such grains can be magnetically aligned if they contain superparamagnetic inclusions. For comparison with observations, we generate synthetic maps of the ratios of U

ϕ
/I and Q

ϕ
/I, which can be used to infer the existence of (magnetically) aligned grains through a negative Q

ϕ
(polarization reversal) and/or a significant level of U

ϕ
/I. We show that two features observed in the existing data, an asymmetric distribution of U

ϕ
with respect to the disk minor axis and a spatial distribution of U

ϕ
that is predominantly positive or negative, are incompatible with scattering by spherical grains in an axisymmetric disk. They provide indirect evidence for scattering by aligned nonspherical grains.

Published: August 2022

The problem of urban soil contamination with heavy metals due to rapid urbanization and industrialization has been a major concern in recent years. A university can be considered as a product of industrialization and urbanization which is associated with different activities that may induce heavy metals pollution into the environment. Therefore, this research work assessed the contamination level of chromium (Cr), copper (Cu), lead (Pb), zinc (Zn) and manganese (Mn) in surface soils of Afe-Babalola university (ABUAD) using various indices. Soil samples were taken from ten (10) different functional sites in the university. These samples were taken to the laboratory and analyzed for chromium (Cr), copper (Cu), lead (Pb), zinc (Zn) and manganese (Mn) using standard method. The mean concentrations of copper (Cu), chromium (Cr) and lead (Pb) were up to 0.75, 0.66 and 0.36 mg/g respectively, while manganese (Mn) and zinc (Zn) were 1.37 and 0.49 mg/g respectively. The average concentration of manganese (Mn) was comparable to its corresponding natural background value, but the average concentration of chromium (Cr), copper (Cu), zinc (Zn) and lead (Pb) were higher. They were approximately of the ratio 1:7, 1:2, 1:3 and 1:2 respectively compared to their corresponding natural background value. The multivariate statistical analyses indicated that vehicles, power generating sets, petrol station, machine workshops, production plants and emissions from outdoor roasted food spots were the major sources of heavy metals contamination on the universitys’ soil. The results from contamination indices and assessment showed that the contamination level of soils within the university can generally be classified as moderately contaminated. Therefore, periodic assessment of the sources and associated ecological risks of the heavy metals is highly recommended. This is to enable decision-makers to effectively manage the environment in the manner that will preserve public and ecosystem health.
