Published: October 2021

В настоящей работе приводятся результаты измерения температурной зависимости сопротивления твердых растворов Ga(1-х)MnхAs со значением х=0.0156. Установлено, что температурные зависимости сопротивления, измеренные вдоль кристаллических осей [110] и [110] в области температур ниже 150 К, носят существенно различный характер. Показано, что при температурах ниже температуры Кюри данные различия могут быть связаны с анизотропией магнитных свойств эпитаксиального слоя Ga(1-х)MnхAs, тогда как при температурах выше температуры Кюри, наблюдаемые различия могут быть связаны с анизотропией подвижности носителей заряда, возникающей из-за наличия в объеме эпитаксиального слоя пространственно ориентированных структур.

Published: October 2021

Одним из важнейших технологических параметров при газофазном получении эпитаксиальных кремниевых Si/Si или гетероструктур типа Si-Ge/Si является содержание галогенидa, осаждаемого из газовой фазы полупроводника в парогазовый смеси с водородом. В работе предложена новая методика расчета концентрации тетрахлорида кремния или любого легирующего галогенида в составе парогазовoй смеси. Эта методика даёт более точное совпадение с результатами прямых измерений содержания тетрахлорида кремния, проведённых различными методами. Использование новой методики расчёта позволяет снизить уровень брака на производстве и повысить однородность параметров наращиваемых слоёв по задаваемым толщине и удельному сопротивлению как внутри, так и между партиями изготавливаемых структур.

Published: October 2021

Повышена стабильность полиэлектролитного антиадгезионного состава добавлением наночастиц SiO2 концентрации от 0.1 до 1.0 мас.%. Использовались наночастицы SiO2 марки Aerоsil размером 100−200 нм, распределение по размерам и трекинг анализ которых производили на анализаторе NanoSight LM10. Дисперсная среда состояла из бидистиллированной воды. В качестве дисперсной фазы использовано индустриальное масло. Исследуемые образцы готовили с использованием воды с наночастицами SiO2, образцы сравнения готовили аналогично, но с бидистилированной водой без наночастиц. Фазовую устойчивость образцов определяли через определенные промежутки времени по выделению дисперсионной фазы и/или появлению границы расслаивания образца. Увеличение стабильности на 20% достигнуто образованием монослоя наночастиц на межфазных границах дисперсной фазы и несущей среды.

Published: October 2021

La SRP (« Space Reference Points ») est une base mondiale, précise, dense et homogène de points 3D géoréférencés qui est réalisée à partir de l’archive d’images SPOT6/7. Ce projet, mené en partenariat entre l’Institut national de l’information géographique et forestière (IGN) et Airbus Defense and Space (ADS), permet le calage géométrique automatique d’images très haute résolution avec une précision de l’ordre de 3m partout dans le monde.

La SRP sur l’Afrique a été produite au cours de l’année 2019. Les contrôles qualité confirment le respect des spécifications attendues pour ce produit. Les particularités des paysages rencontrés sur ce continent ont conduit à intégrer de nouvelles fonctionnalités à la chaîne de production. Tout d’abord, la sélection des images SPOT6/7 a été enrichie sur la zone intertropicale en prenant en compte les masques de nuage fournis avec les produits, permettant d’obtenir une densité de points SRP optimale pour la zone. Ensuite, un prototype de socle de calage exploitant des ortho-images Sentinel-2 a montré la capacité de cette méthodologie à assurer la spécification de localisation à 3m sur un archipel d’îles (ici le Cap Vert). Afin de valider pleinement le produit, l’article présente deux tests d’exploitation sur le Nigéria pour des productions 2D et sur la ville de Marrakech pour des productions 3D. Ils démontrent la capacité de la SRP à caler différents types d’images et à atteindre la cible de précision de la base. La SRP est destinée, dès 2021, à assurer le calage d’images dans différents projets et notamment, de façon massive, dans le segment sol Pléiades Neo.

Published: October 2021

Purpose: This retrospective study compares point-of-care ocular ultrasound to MRI in order to establish preliminary data for and identify challenges to a multicenter study into the utility of ocular ultrasound for diagnosing optic neuritis. Methods: Our ultrasound archive was queried to identify subjects suspected of having optic neuritis who underwent ocular ultrasound and MRI of the brain or orbit. Blinded ultrasounds were reviewed by ultrasound faculty. The presence of optic disc elevation, optic nerve, or sheath dilation, and overall impression were recorded and compared to MRI results. Sensitivity and specificity of each ultrasound finding and the overall impression, as well as agreement between the raters, were calculated. Results: Sensitivity and specificity of ultrasound for MRI confirmed optic neuritis was 100 % (95 % CI 54.1-100) and 58.3 % (95 % CI 27.7-84.8). Optic nerve sheath diameter had nearly perfect agreement (κ = 0.8828), however agreement on optic disc elevation (κ = 0.5641), nerve diameter (κ = 0.2174), and overall agreement (κ = 0.1818) were moderate, fair, and poor, respectively. Conclusions: This preliminary study estimates test characteristics of ocular ultrasound for the diagnosis of optic neuritis for the purposes of power analysis and to identify potential pitfalls in preparation for a larger prospective investigation.

Authors: Frances McNamara Isabella , Rizzi Scott , Still Bryan , Shah Harsh
Published: October 2021

A 69-year-old woman presented with progressive lethargy and encephalopathy of two weeks duration. Initial laboratory workup revealed hypercalcemia; imaging was notable for a 16 cm by 16 cm right lower quadrant abdominal mass. Core biopsy revealed germinal center Diffuse Large B-Cell Lymphoma (DLBCL). Despite correction of her hypercalcemia, the patient’s encephalopathy persisted. Brain imaging, thyroid stimulating hormone (TSH), folate, B12, urinalysis and culture, antinuclear antibody (ANA), and ammonia were normal. Cerebrospinal fluid (CSF) was negative for leptomeningeal disease. A thiamine level was sent and found to be low. Aggressive repletion was pursued; following the first cycle of chemotherapy, the patient’s mental status normalized. This is a rare case in which the rapid turnover of cells in the setting of active malignancy is believed to play a role in the development of thiamine depletion and resultant encephalopathy.

Students in higher education have been shown to have difficulties in developing their critical thinking skills, such as analysis and problem solving, reasoning and argumentation. Open-ended tasks offer opportunities for students to develop their own interpretations of various sources, to critically analyse domain-specific knowledge and utilize that knowledge in their argumentation. This study focuses on the ability of new Master’s students (n=37) to utilize pharmaceutical knowledge from different sources in producing written arguments and counter-arguments in the context of open-ended assignment task. The data were analysed by qualitative content analysis. The results showed that there was substantial variation in how students analysed and processed pharmaceutical knowledge as well as how they utilized that knowledge in their argumentation. While some students were able to provide comprehensive analysis of the different sources, others superficially analysed and processed the sources and struggled to generate convincing arguments. Students’ written responses were typically one-sided: only a few students provided counter-arguments associated with the pharmaceutical problem-solving situation presented in the task. Understanding the nature of the challenges in argumentation and knowledge processing encountered by pharmacy students can help pharmacy educators to modify their pedagogical practices to better support students’ learning.

The level of fatigue among medical students is increasing. Exhaustion is an essential symptom of burnout, which may occur even while a student. Our exploratory study sought to identify the characteristics of tired students and to describe factors determining fatigue among medical students. The studied group consisted of second-year medical students (N=193) from a Polish medical university. Statistically significant differences in fatigue appeared between male and female students. We obtained positive correlations between intensity of fatigue and sleepiness, pain intensity, stress, anxiety, depression and negative health conditions, life satisfaction, emotional stability, conscientiousness, and self-efficacy. Predictors relevant for female fatigue were sleepiness, health condition, depression, and conscientiousness (the whole model explains 46% of variance in fatigue). Predictors relevant for male fatigue were sleepiness, health condition, anxiety, and agreeableness (the whole model explains 55% of variance in fatigue). We did not observe differences in fatigue between sleepless, overloaded, or stressed people. Explaining the differences between male and female predictors and levels of fatigue in terms of personality traits through the prism of defined stereotypical social roles is worth considering.

Based on many years of research experience of water techno-ecosystems of thermal and nuclear power plants a brief review of the main patterns of formation of the composition, cenotic structure, elements of the functional organization of benthos and periphyton communities was made. It was shown that the composition of zoobenthos and zooperiphyton in some cooling ponds, other technical water bodies and watercourses was quite rich. In addition, due to the rather intensive invasive process, the list of taxa is constantly expanding. Species of tropical and subtropical origin have been recorded. Of particular importance is the invasion of species that may be the cause of bio-hindrances in the operation of power plant equipment. Techno-ecosystems have been studied to varying degrees. One of the most studied for a long time are the cooling ponds of Khmelnitsky and Chernobyl nuclear power plants. Hydrobiological research and monitoring at the first one has been carried out for more than 20 years. It was found that the influence of biotic invasion (invasion of Dreissenidae) may have a significant impact, comparable to extreme technogenic factors, on both the ecosystem and technical water supply facilities. The stages of contourisation and decontourisation processes in the Khmelnitsky NPP techno-ecosystem were established. At the Chernobyl NPP cooling pond, studies were carried out during all periods of the existence of the reservoir and the power plant, until the process of uncontrolled pond descent and transforming it into a unique wetland. Based on the obtained data, practical recommendations relating to the organization of hydrobiological and environmental monitoring, as well as reducing biological hindrances and improving the reliability of power plant equipment have been developed.

Objective: To explore the therapeutic mechanism of microporous sheep acellular dermal matrix (ADM) combined with human umbilical cord mesenchymal stem cell (hUCMSC) to promote the healing of full-thickness skin defect.Methods: hUCMSC was co-cultured on microporous sheep ADM to form composite biological dressings. Seventy-two nude mice were selected to make full-thickness skin injury models and randomly divided into 3 groups (hUCMSC + microporous sheep ADM group, sheep ADM group and iodophor gauze group), with 24 mice in each group. The wound healing rate of each group was detected at 14 d, 21 d and 28 d after operation, qRT-PCR technique was used to detect the expression of Bax and Bcl-2 in the wound tissues, and the immunohistochemical staining technique was used to detect the expression of Collagen I and vascular endothelial growth factor (VEGF). Data were analyzed with one-way ANOVA and t test.Results: At 14 d after operation, the wound healing rate of the hUCMSC + microporous sheep ADM group was (65.34 ± 14.72)%, which was significantly higher than that of the iodophor gauze group [(37.54 ± 10.21)%], and higher than that of the sheep ADM group [(49.08 ± 11.16)%], the differences were statistically significant (t = 19.52, 14.72; p < .05). With the gradual healing of the wound, at 28 d after operation, the wound healing rate of the hUCMSC + microporous sheep ADM group was (98.63 ± 15.41)%, which was significantly higher than that of the iodophor gauze group [(81.74 ± 16.27)%], and higher than that of the sheep ADM group [(63.47 ± 14.80)%], the differences were statistically significant (t = -16.42, 20.35; p < .05). The expression of Bax in the wound tissues of the hUCMSC + microporous sheep ADM group was significantly reduced, especially at 21 d after operation, the expression level was 0.25 ± 0.06, which was significantly lower than the iodophor gauze group (0.53 ± 0.16) and the sheep ADM group (0.41 ± 0.12), the differences were statistically significant (t = 3.52, -2.83; p < .05). The expression of Bcl-2 in the wound tissues of the hUCMSC + microporous sheep ADM group was significantly higher than those ofthe other two groups, especially at 21 d after operation, the expression level was 0.63 ± 0.19, which was significantly higher than the iodophor gauze group (0.34 ± 0.09) and the sheep ADM group (0.46 ± 0.13), the differences were statistically significant (t = 5.31, -6.07; p < .05). Immunohistochemical detection showed that the expression of Collagen I and VEGF in the hUCMSC + microporous sheep ADM group was slightly more than that of the sheep ADM group and the iodophor gauze group, but the effect was not remarkable.Conclusions: hUCMSC + microporous sheep ADM composite dressing can promote the healing of the full-thickness skin injury and reduce the production of apoptotic cells by carrying hUCMSC.

This research aimed to investigate the level of test anxiety and the relationship between test anxiety and self-esteem among the students of the faculty of Science and Arts in Rafha campus, Northern Border University, KSA during the COVID-19 pandemic. In addition, it intended to identify the differences in test anxiety among the students according to gender variable. The researcher applied the descriptive method, prepared a preliminary data form, and used the Westside Test Anxiety Scale by Driscoll (2007) and the Self-esteem Scale by El Sayed (2019). The data were collected online, and the sample size was (336) students. The results showed that the level of test anxiety among the students of the faculty of Science and Arts during the COVID-19 pandemic was high. The correlation coefficient between the impairment subscale and self-esteem was negative but statistically insignificant. Moreover, the correlation coefficients between both the worry subscale and the test anxiety total scores with the self-esteem resulted in a negative sign and statistically significant. There were significant differences in test anxiety among the students in the impairment subscale, the P-value was (0.005), which indicates that the difference between the two means is statistically significant, and the males’ mean is greater. While the P-value for the worry subscale was (0.226), which indicates that the difference was insignificant, the P-value of the test anxiety total scores was (0.029), which reveals that the difference between the two means is statistically significant, and the males’ mean is greater.

This study was part of the Manipulation of Moisture and Nutrient Availability in Young Regrowth Forests in Eastern Amazonia Project (MANFLORA). The experiment was designed in completely randomized blocks containing control and irrigated treatments during the dry period (5 mm of water/day), with four repetitions each. The monthly mean litter values ranged from 316.10 to 997.90 kg ha-1 month-1. The magnitude of this phenomenon can be explained by the functional role of the floristic structure, represented by the species Myrcia sylvatica (G. mey) DC., Myrcia bracteata (Rich) DC., Miconia ciliata (Rich) DC., Lacistema pubescens Mart., Lacistema aggregatum (Berg.) Rusby, Vismia guianensis (Aubl.) Choisy, Cupania scrobiculata Rich. and Ocotea guianensis Aubl., which constituted the determinant factors, associated with the hydroperiodic effect and ecosystem manipulation. The monthly mean of the analytical results of mass treatments were significant (P < 0.05), however, when compared annually there was no significance, which indicates seasonal influence, since the period of greatest deposition is the dry one, regardless of the water manipulation along the period studied. Only in time the mass values of Ca and Mg were not significant for treatment (P < 0.05). The amount of Ca was significantly (P < 0.05) higher than that of Mg.
Seasonal and Regional Chemical Variability of the Wild Population of Lantana camara Leaf Essential Oil From Kenya

Published: October 2021

Studies examining the variability in wild plant metabolic expression propose that environmental factors significantly influence the essential oil (EO) quality and quantity in a plant. Lantana camara is a widely distributed invasive plant species worldwide. However, its immense metabolites can become a source of novel compounds to produce biopesticides in the agricultural industry. Although, the quality aspect has to be considered due to the environmental influence on the metabolites synthesised. Therefore, this research aimed to understand the influence of environmental factors and how it shapes the plant’s metabolite profile in multiple populations of L. camara. Leaf samples were collected from six different geographic regions of Kenya and the corresponding monthly climatic data and soil samples. GC-MS data from leaf EO were analysed with environmental variables (climate and soil data) using unimodally unconstrained and constrained ordination methods for untargeted metabolomics analysis. Partial Least Squares-Discriminant Analysis (PLS-DA) and Random Forests (RF) were used to confirm the variability further. Seasonal and regional variability was observed for secondary metabolites (SMs) in the leaf EO, which correlated to climatic factors and soil attributes. We highlight the season-al-geographic metabolism relationship for L. camara and the combined analytical approach to obtain data that contributes to understanding the influence of environmental factors on the synthesis and accumulation of SMs. This research will have all-embracing implications for maximising phytochemical uniformity.
New sperm whale remains from the late Miocene of the North Sea and a revised family attribution for the small crown physeteroid Thalassocetus Abel, 1905
Authors: ALFSEN Apolline , BOSSELAERS Mark , LAMBERT Olivier
Published: October 2021

In spite of a continuously expanding physeteroid fossil record, our understanding of the origin and early radiation of the two modern sperm whale families Kogiidae Gill, 1871 (including the pygmy and dwarf sperm whales, Kogia spp.) and Physeteridae Gray, 1821 (including the great sperm whale, Physeter Linnaeus, 1758) remains limited, especially due to the poorly resolved phylogenetic relationships of a number of extinct species. Among those, based on fragmentary cranial material from the late early to middle Miocene of Antwerp (Belgium, North Sea basin), the small-sized Thalassocetus antwerpiensis Abel, 1905 has been recognized for some time as the earliest branching kogiid. The discovery of a new diminutive physeteroid cranium from the late Miocene (Tortonian) of Antwerp leads to the description and comparison of a close relative of T. antwerpiensis. Thanks to the relatively young ontogenetic stage of this new specimen, the highly modified plate-like bones making the floor of its supracranial basin could be individually removed, a fact that greatly helped deciphering their identity and geometry. Close morphological similarities with T. antwerpiensis allow for the reassessment of several facial structures in the latter; the most important reinterpretation is the one of a crest-like structure, previously identified as a sagittal facial crest, typical for kogiids, and here revised as the left posterolateral wall of the supracranial basin, comprised of the left nasal (lost in kogiids for which the postnarial region is known) and the left maxilla. Implemented in a phylogenetic analysis, the new anatomical interpretations result in the new Belgian specimen and T. antwerpiensis being recovered as sister-groups in the family Physeteridae. Consequently, the geologically oldest kogiids are now dated from the Tortonian, further extending the ghost lineage separating these early late Miocene kogiid records from the estimated latest Oligocene to earliest Miocene divergence of kogiids and physeterids.
Entrepreneurship in Serbian enclaves in region of Kosovo and Metohia: Post-conflict situation and possible moderating function of small enterprises regulation

Published: October 2021

On the sample of 84 Serbian companies which operate on Kosovo territory (Serbian enclaves) in post-conflict situation we explored which factors are crucial for their survival and success. Also, we want to find out is EU regulatory document for small enterprises helpful for them in this situation. We did not find EU document helpful in this situation. The results have confirmed that the enterprises are aware that expanding the market range is the only real and sustainable method of developing their activities. The key limiting factor in expanding the market range is the unfair competition. Furthermore, we are particularly pleased with the fact that enterprises from the northern part of Kosovo and Metohia are aware of the importance of innovative activities, and they realized that in contemporary business world it is possible to survive and grow in the market only by developing and introducing innovations. There are no universal solutions in a post-conflict situation. Search for ideal solution for developing the entrepreneur activities and it depends on the combination of social/political, institutional, cultural and economic aspects.
Organic plant products are of more improved chemical composition than conventional ones
Authors: Golijan Jelena , Sečanski Mile
Published: October 2021

Considering the negative effects of conventional agricultural production, organic food production is a sustainable approach to production, which preserves the environment and protects human health. Organic products are products of high quality, without residues of pesticides and other harmful chemicals. Through the review of literature data, the authors of this paper presented a comparative study on the chemical compositions of organically vs. conventionally grown plants and their products. Dry matter, nitrates, sugars, vitamins, macro-and microelements, as well as, secondary metabolites have been singled out. The analysis of collected data revealed that organic products contained more dry matter, significantly fewer nitrates, fewer proteins and a higher proportion of amino acids, more sugars, vitamin C, numerous macro-and microelements (particularly Fe, Mg and P), more polyphenols and they had higher total antioxidant capacity than conventional products. Although many authors have been dealing for many years with the comparison of the nutritional composition of organic and conventional food products, a clear consensus whether organic products have an improved chemical composition compared to conventional products has not been reached yet, i.e. the conclusions are ambivalent. Therefore, further long-term studies are necessary to clarify the existing doubts.
Questões de gênero e sexualidade na educação brasileira
Authors: Gomes Filho Antoniel dos Santos , Silva Lielton Maia
Published: October 2021

O presente estudo, em tela ou em mãos, tem como objetivo: apresentar e discutir como as questões de gênero e sexualidade perpassam a educação brasileira. Metodologicamente, possui uma abordagem qualitativa, em nível exploratório, de tipo bibliográfico. Destaca-se que autores/as como Guacira Lopes Louro, Judith Butler, Miguel Arroyo são apresentados no desenvolvimento da discussão. Pode-se considerar a partir do estudo que os processos educacionais (formais e informais) são atravessados por uma norma que toma como base a heterossexualidade como norteadora, e que as escola e universidades constituem-se como espaços de violência (física e simbólica) onde as pessoas LGBTQI+ podem ser alvos de homofobia por conta de suas vivências no âmbito da sexualidade.
