Structure of finite groups, in which any pronormal subgroup is either normal or abnormal
Authors: Pypka A.A.
Published: March 2021

A subgroup $H$ of a group $G$ is said to be abnormal in $G$ if, for each element $g \in G$, we have $g \in {<}H, H^g{>}$. A subgroup $H$ of a group $G$ is said to be pronormal in $G$ if, for each element $g \in G$, the subgroups $H$ and $H^g$ are conjugate in ${<}H, H^g{>}$. We describe all finite groups, each pronormal subgroup in which is either normal or abnormal.

Authors: Suljević D. , Hamzić A. , Islamagić E. , Fejzić E. , Alijagić A.
Published: March 2021

This research presents the first findings on thrombopoiesis for Wistar rats. Haemopoietic cells from the femur and the sternum were analysed by light microscopy in combination with infrared and near-ultraviolet light for fine cytoplasmic structure analysis. Five main types of thrombocyte precursor cells were identified in the bone marrow samples: megakaryoblast, promegakaryocyte and megakaryocyte (basophilic, acidophilic and thrombocytogenic). More intensive thrombopoiesis and morphologically differentiated cells were found in sternum samples.
The “Last Word” in Pictures: Enhanced Visual Interpretation of Revelation in Luther’s High German Bible (1534)
Authors: Campbell W. Gordon
Published: March 2021

For the last twenty-five years of his life, Martin Luther and his associates were active in Bible translation, publishing first the New Testament, from 1522 onwards, and by 1534—at roughly the mid-point of these endeavours—the whole Bible in German. Across this entire period, until his death, Luther continuously offered reader-viewers of the final New Testament book, Revelation, not only verbal commentary—in a preface (1522), or replacement preface with accompanying marginal notes (1530)—but visual exegesis, in the form of successive series of woodcut engravings designed to illustrate the text. A set of images commissioned for Luther’s 1534 German Bible was the crowning achievement of this visual interpretation: the 1534 Bible even extended pictorial illustration and adornment to the Gospels and Epistles, as well as Old Testament texts. From the perspective of art history, to regard these acclaimed illustrations as “the last word in pictures” represents no novelty, for the 1534 Luther Bible has long been counted among “the finest things that the art of printing produced in the Reformation period” (Schramm 1923, 22–23; my translation). However, to make the same assertion about the Revelation illustrations specifically, from an explicitly exegetical standpoint—and in English—is new and requires substantiation through supporting evidence. I will provide this through close analysis and evaluation of the interpretative moves that the 1534 images make, in conjunction with Luther’s translation and comment, over and against the visual exegesis of their predecessors created, from 1522 onwards, for Luther’s German New Testament.
Sitting Alone with a Text
Authors: Lohr Joel N.
Published: March 2021

This essay explores how frameworks of education in the United States have been shaped by particularly Protestant ideals—and, especially, how notions concerning individuals and their engagement with texts have had an outsized influence on educational practice. Following an examination of a number of historical issues related to our topic, and in particular Protestantism and the rise of the printing press, I examine the foundations of American education, including Puritan models of schooling as religious instruction. This leads to a discussion of the birth of Pluralism and Fundamentalism in the United States, which in turn leads to some reflections on the current educational milieu in this context, especially as related to religious identity in the classroom and higher education more generally. I suggest that a greater awareness of the cultural values that are embedded in our educational practices is vital if we are going to be responsive to the needs of increasingly diverse student populations.
Ehud, Stigma, and the Management of Spoiled Identity
Authors: Chalcraft David J.
Published: March 2021

The story of Ehud, and his assassination of the Moabite King Eglon (Judges 3: 12–30), continues to entertain readers and hearers alike. The story also perplexes, largely on moral grounds. This paper utilises the sociology of Erving Goffman and insights from disability studies to re-tell the story of Ehud as someone who is doubly stigmatised. That is, Ehud not only carriers the stigma of left-handedness but is also disabled; moreover, the Moabite King is also disabled/immobile because of his obesity. I take the biblical text as conveying that Ehud is left-handed by necessity given the impairment in his right hand/arm. Adopting a social model of disability, I apply Goffman’s account of the management of spoiled identity developed in his book Stigma (1963) to explore how the narrative depicts various dimensions of social stigma and Ehud’s moral career as he attempts to manage his spoiled identity and the degrees of societal acceptance and rejection he experiences in different contexts. The key arguments of Goffman are summarised before I apply central concepts from Goffman to the biblical story. Concepts include “moral career,” the distinction between social, personal and ego (self-) identity, and the key distinction between a person with a stigma being discredited (because the impairment is obvious and seen by all), on the one hand, or bearing a stigma that is discreditable (that is, it would discredit them if found out), on the other.

The number of criminal cases against doctors has increased in recent years. The major reason for them was failure in delivery of any medical services that resulted in harm to health or death of the patient. The legislation of the Russian Federation for the medical industry is imperfect, however, the health care delivery failure can be associated with doctors’ non-compliance to the action algorithms specified by regulatory acts. The review has collected up-to-date legislative information regarding polypharmacy, off-label drug administration, irrational antibiotic therapy, that are neglected by doctors. Although, these problems become more and more crucial and they arouse interest of investigation bodies.
Mecânica estatística de sistemas complexos
Authors: Tsallis Constantino
Published: March 2021

A magnífica mecânica estatística de Boltzmann-Gibbs, amálgama de primeiros princípios e teoria de probabilidades, constitui um dos pilares da física teórica contemporânea. Entretanto, ela não se aplica a grande número dos sistemas ditos complexos, caracterizados essencialmente por um forte emaranhamento espaço-temporal de seus elementos. Revisamos aqui a proposta de generalização chamada mecânica estatística não extensiva, que emergiu em 1988. Ela está baseada em entropias não aditivas (com índice q ≠ 1), em contraste com a entropia de Boltzmann-Gibbs-von Neumann-Shannon, que é aditiva (com índice q = 1). Sua fundamentação básica, assim como aplicações selecionadas em física e fora dela, são brevemente descritas.
Física estatística aplicada à neurociência de estados alterados: o cérebro sob influência de psicodélicos
Authors: Viol A. , Felippe Jr. H. , Palhano-Fontes Fernanda , Onias Heloisa , de Araujo Draulio B. , Viswanathan G. M.
Published: March 2021

O objetivo principal da mecânica estatística é relacionar a física microscópica regida pelas leis de Newton, ou então pela mecânica quântica, com a física macroscópica regida pelas leis da termodinâmica. Conceitos macroscópicos, tais como a temperatura, que não fazem sentido do ponto de vista microscópico, surgem na mecânica estatística como propriedades emergentes quando o número de partículas torna-se suficientemente grande. O sucesso da mecânica estatística em explicar e prever uma variedade de fenômenos macroscópicos motivou a aplicação de conceitos e métodos da física estatística ao estudo de sistemas complexos e redes complexas, inclusive em neurociência. Nosso objetivo neste trabalho é aplicar essa abordagem a um problema chave na neurociência: como entender quantitativamente os correlatos neurais de estados mentais alterados de consciência induzidos por substâncias psicodélicas? Vamos primeiro introduzir alguns conceitos básicos sobre a conectividade funcional das regiões do cérebro. Discutimos então a fenomenologia e a neurociência relacionadas aos psicodélicos. Finalmente, resumimos alguns estudos que aplicaram a física estatística e a teoria de redes complexas para tentar melhor entender o comportamento do cérebro sob influência dos psicodélicos.

Authors: Bacelete Viviane Souza Bicalho , Gama Ana Cristina Côrtes
Published: March 2021

ABSTRACT Purpose: to conduct a literature review on the therapeutic effects of photobiomodulation applicable to speech-language-hearing therapy. Methods: the databases searched were the Cochrane Library, Virtual Health Library, Medical Literature Analysis and Retrieval System Online (MEDLINE) via PubMed, and Web of Science/ISI.The selected articles were original ones whose abstracts were available and that evaluated the therapeutic effect of photobiomodulation in situations related to speech-language-hearing practice. Results: the sample comprised 23 articles, most of them being indexed in PubMed. The fields of health with the largest number of publications were Physical Therapy and Medicine. The sample size ranged from1 to 99 people, aged 15 to 77 years, and the most applied wavelength was the infrared one. Most of the studies had positive photobiomodulation application results - although in a few publications the effects of this treatment modality were assessed in a combination with rehabilitation exercises. Conclusion: photobiomodulation benefits different disorders treated by speech-language-hearing therapists, however, there is a broad methodological diversity, lacking specific protocols for the ideal dosimetry for each disorder.

The 30th Anniversary of Fall of the Berlin Wall and Russian-German Relations as Reflected in the Media
Authors: Voronenkova Galina , Gaponova Elena
Published: March 2021

The article deals with mass media impact on Russian-German relationships after the fall of the Berlin Wall, which used to divide the world into two socio-political systems. This remarkable event of the XX century has never lost its topicality in the media. The authors make a retrospective analysis of stages of the two countries bilateral relations development. The research shows that the bilateral and world wars have greatly influenced Russians and their perception of Germany and its subjects. At the same time, due to the wars, perception of Russians by Germans has also been ambiguous. The article studies the role of the mass media in the deterioration in state-to-state relations in the recent years in the context of the information war. The current shift in the vector of Russian-German relations has inevitably found its reflection in the media. It was the commentariat that, being a powerful international political and communication tool, gave impetus to the massive promotion of the negative image of Russia, which was fuelled by the crisis in the EU and global sanctions. All this has resulted in Russias becoming a key villain-like character in the global media landscape whose image is influencing a large number of current processes in the world. The authors have analyzed interpretations of over 500 media texts dealing with Russian-German relations, both in Russian and in German, and highlighted such components as fake news and post-truth as applied in political media discourse.

Analysis of the influence of coke quality on the production of pig iron in the conditions of JSC “Ural Steel”
Authors: Ganin D. R. , Fuks A. Yu.
Published: March 2021

The purpose of the study was to conformity of the quality of coke used in the blast-furnace shop of JSC “Ural Steel” meets the requirements recommended in the scientific literature, and to study its impact on the consumption of coke and the production of pig iron at the enterprise. For the study, the blast furnace № 1 with a useful volume of 1007 m3 and the blast furnace No. 4 with a useful volume of 2002 m3 were selected. The results of the analysis of data on the quality of coke over a three-year period: ash content, volatile matter and sulphur in the coke, the moisture content in the coke, the coke uniformity coefficient, indicators of the cold strength of coke (M25 and M10), indicators of coke hot strength (CSR) and reactivity of coke after high-temperature interaction with CO2 (CRI). Studies have revealed significant instability of the moisture content in the coke, which affects the change in its consumption, and heterogeneity of the granulometric composition of the coke, increasing the stability and uniformity of which would favorably affect the indicators of the blast furnace process. It was found that the values of the indicators of M10 coke attrition, hot strength of coke (CSR) and reactivity of coke (CRI) do not meet the recommendations of domestic and foreign scientists. Measures are proposed to improve the quality of coke, the implementation of which will increase the productivity of blast furnaces and reduce the consumption of coke per ton of pig iron.
Silver 50 kopecks coins made by the metallurgist and the Mining Institute graduate Petr Latyshev

Published: March 2021

This paper continues a series of publications on the history of Russian silver 1 Rouble coins and the contribution of the Saint Petersburg münzmeisters, who graduated from the Mining University, to the coin business. The study focused on silver 50 Kopecks coins of the 1922–1924ss made by the former münzmeister of the Saint Petersburg Mint Petr Latyshev, who graduated from the Mining School. A study of archives confirmed his involvement in the minting of the first silver coins issued by the Soviet State in the 1920s at both the Leningrad Mint and the London Mint. The authors examined silver 50 Kopecks coins of the 1922–1925ss and established certain features of their production. By means of modern technology, the authors examined the distribution of chemical elements across the surface and defined the structure of the silver matrix. A relationship was established between certain elements and the hardness of different areas of the coin. All experiments were conducted using state-of-the-art equipment of specialized laboratories at the Saint Petersburg Mining University. The new approach to the study of historic artefacts enables to get a deeper insight into the production technology that was used. Vickers microhardness tests helped establish that the segregation can be primarily linked to such elements as nickel, copper and lead, which may affect the quality of the final product if their concentration is high. This research study was carried out as part of the preparation research work for the exhibition of the Coin Collection of the Saint Petersburg Mining University’s Museum of Mining, as well as in the framework of the cooperation agreement signed on 29/11/2019 between the Saint Petersburg Mining University and the Museum für Naturkunde at the Leibnitz Institute for Evolution and Biodiversity Science in Berlin, Germany.
Properties of welded joints of the Al – Zn – Mg – Ca alloy doped by microadditivies of zirconium and scandium
Authors: Shurkin P. K. , Karpova Zh. A. , Musin A. F. , Latypov R. A.
Published: March 2021

This work is devoted to the study of the structure and properties of welded joints of hot-rolled sheets from the aluminum alloy Al – 4%Zn – 2.5%Mg – 2.5%Ca – 0.2%Zr – 0.1%Sc. The joints were obtained by manual argon-arc method (TIG-welding) using a wire of own production from the base metal composition (sample AlCa) and standard welding wire Of SvAMg5 alloy (sample AlMg). It is shown that in the cast state the alloy structure consists of an aluminum solid solution (Al) (which contains 2.9% Zn, 2.5% Mg, 0.28% Zr and 0.12% Sc) and eutectic crystals of the phase (Al, Zn)4Ca with a volume fraction of ~7.6%. Microstructural investigation of wrought products showed that the formation of a structure consisting of an aluminum matrix and uniformly distributed spherical particles with a diameter of less than 2 microns occurs as a result of hot rolling with a compression ratio of 95%. The quality of welded joints produced using different additives meets the requirements for the absence of internal defects. The structure in the middle of the joints corresponds to the cast structure of the alloy and has hardness (~80 HV) inferior to the hardness (~105 HV) of the main deformed alloy. Heat-affected zone retains a relatively high hardness (at 95 HV), which is associated with a stabilizing effect of dispersed particles of the eutectic phase (Al, Zn)4Ca, and also presence of nanoparticles of the phase Al3(Zr,Sc) in the original sheet. Additional annealing of welds at 350 oC resulted in degradation of the hardness of the AlMg sample to less than 70 HV and relative cross-sectional hardness equalization in the AlCa sample to more than 90 HV. This effect can be explained by the dispersion hardening in case of the AlCa sample due to the separation of coherent nanoparticles of the Al3(Zr, Sc) phase with the L12 structure during the decay of a supersaturated aluminum solid solution. The results of mechanical tests confirmed the advantages of the strength properties of the AlCa sample over the values of the AlMg sample. All samples in the initial state and annealed sample AlMg have strength coefficients relative to the base metal from 72.4 to 75.3. The greatest mechanical properties can be achieved in the welded joint AlCa in the annealed state: UTS = 274±2 MPa, YS = 181±20 MPa, El = 2.9±0.8 %, which corresponds to a coefficient of more than 80%. This paper was prepared in the framework of the Assignment No. 11.2072.2017/4.6 for implementing a project on the following subject: Developing a process for obtaining deformed semi-finished products made of aluminium-matrix eutectic composites hardened with L12 phase nanoparticles with no quenching applied.
Humor y registros lingüísticos: un análisis de las columnas "Cuarentena en la España vacía", de Daniel Gascón

Snowfall and snow cover evolution in the Eastern Pre-Pyrenees (NE Iberian Peninsula)
Authors: Bonsoms J. , Salvador-Franch F. , Oliva M.
Published: March 2021

Snow cover has significant impacts on geoecological dynamics as well as on socio-economical systems. An accurate quantification of snow precipitation patterns in mountain regions is needed to better understand the spatio-temporal implications of snow cover. The objective of this work is to characterize the patterns of solid precipitation and snow cover in two high Mediterranean massifs. To this purpose, we analyse instrumental data series of snowfall and snow depth of Port del Comte (2316 m a.s.l.) and Cadí-Nord (2134 m). Both stations are situated in the eastern Pre-Pyrenees and include 14 consecutive snow seasons from November to May, allowing to (i) explore the dependence of the main drivers of snowpack: temperature and snowfall; (ii) find out the most frequent circulation weather types associated with high intensity snowfall events, and finally (iii) investigate the role of the North Atlantic Oceanic (NAO) teleconnection pattern explaining snow cover evolution during the winter season. Data show that snowfall is controlled by similar weather types in both stations that resulted in similar snowfall averages: 205 cm and 258 cm at Port del Comte and Cadí-Nord, respectively. Nevertheless, local factors interfere with the amount of snow depth recorded, which is moderately different between stations. Whereas Cadí-Nord records a seasonal mean of 66 cm, Port del Comte records a smaller quantity of 25 cm with a high interannual and seasonal variability. In fact, snowfall recurrence, snow amount or duration in the ground is considerably variable among years (CV>20). In these stations, snow cover duration is determined by the precipitation in the form of snow falling during the previous months. Snowfalls in moderate to severe episodes (>15 cm in 24 h) are mainly driven by Atlantic flows, mostly from NW. In addition, NAO pattern is negatively correlated with snowfall in November and December months (R>-0.50), showing a weaker and not statistically significant correlation during the rest of the winter season.

Published: March 2021

Sexual abuse is committed not only by adults but also by minors. The legal process upon children who have committed sexual abuse refers to the Law Number 11 of 2012 on the Juvenile Court System. The purpose of this study is to find out the factors to be considered by the panel of judges in imposing penalty upon the perpetrators. The study employs both normative and empirical approaches. It is found with regard to the liability issue, the panel of judges relies on both juridical and non- juridical consideration. In sexual abuse case that was tried in Kebumen District Court, beside imposing imprisonment, the panel of judges also ordered the perpetrators to undergo work training as a substitute of fine.

This study investigated associated risk factors for bacterial urinary tract infection among internally displaced pregnant women in Niger Delta camps. The objectives of the study were to determine the association between age, parity, trimester of pregnancy, religion and the incidence of bacterial urinary tract infection among internally displaced pregnant women. The population of the study comprised 108 internally displaced pregnant women who also formed the study sample as no sampling method was adopted due to the limited number of study participants. The tools for data collection was midstream urine samples collected using sterile screw-capped universal containers, the instruments used in isolating the bacterial uropathogens, include Cysteine-Lactose Deficient (CLED) agar, MacConkey and Nutrient agar plates as well as a structured checklist in socio-demographic characteristics of the pregnant women. Descriptive statistics of frequency and percentage were used for data analysis and the Statistical Package for Social Sciences (SPSS) software was employed in the analytical process. Results from the study showed there was no significant association between age, parity, trimester of pregnancy, and the incidence of bacterial urinary tract infection among internally displaced pregnant women (P>0.05). However, religion was significantly associated with the incidence of bacterial urinary tract infection among internally displaced pregnant women (P<0.05).  The study concluded that there is an increasing incidence of bacterial urinary tract infections among internally displaced pregnant women linked to religious beliefs.  Based on the study findings, early routine screening of all internally pregnant women presenting or not presenting with clinical symptoms of urinary tract infection is recommended. The need for good personal and environmental hygiene to be encouraged in internally displaced persons’ camps.

Relevance. Providing the population with functional, environmentally friendly and high-quality food is an urgent scientific and state problem. With prolonged use of contaminated products, the risk of various diseases increases. Therefore, the human diet should consist of functional, environmentally friendly products. The main goal of this research work was the production of high-quality jam from environmentally friendly raw materials of plant origin.

Methods. For the preparation of the jam, the fruits of the Sosnovsky zucchini variety and the Lada melon of the technical and biological degree of maturity were used. The technological process of making jam took place in accordance with the technological requirements for this type of product. The content of biochemical parameters: dry matter, the amount of sugars, pectin and nitrates) were determined in fresh and finished (after the fermentation period) products.

Results. Jam with a melon aroma was obtained with a glucose content of 4.5-6.73%, fructose - 4.66-7.17% with an accumulation of nitrates in the range of 127.1 mg / kg (fruits of biological maturity) and 131.6 mg / kg (fruits of technical maturity), which is 3.0-3.1 times lower than the maximum permissible concentration. The tasting committee rated the jam made from fruits of technical maturity at 4.3 points, and biological at 4.8 points. Thus, summarizing the results of our research, we can conclude that the jam made from zucchini fruits with the addition of melon is a functional, high-vitamin, environmentally friendly food product with high taste.
Nowy system warunkowości w prawie Unii Europejskiej
Authors: Gontarski Waldemar
Published: March 2021

Autor omawia zgodność z prawem traktatowym projektowanego systemu warunkowości, dotyczącego zawieszania wypłaty funduszy unijnych państwom członkowskim w związku z zarzutem naruszania praworządności i innych zasad ogólnych. Tak rozumiana nowa warunkowość rozpatrzona została w kontekście dotychczasowego uzależniania wydatkowania funduszy unijnych (a wcześniej wspólnotowych) od spełnienia określonych kryteriów jako utrwalonej praktyki zarządzania funduszami.

Celem niniejszego opracowania jest zbadanie zgodności z prawem traktatowym nowego systemu warunkowości dotyczącego ochrony praworządności i innych zasad ogólnych postulowanego w konkluzjach Rady Europejskiej z 17–21.07.2020 r. jako kontynuacji prac nad projektowanym przez Komisję rozporządzeniem Parlamentu Europejskiego i Rady w sprawie ochrony budżetu Unii w przypadku uogólnionych braków w zakresie praworządności w państwach członkowskich z 2.05.2018 r.
Leasing jako źródło finansowania samodzielnych publicznych zakładów opieki zdrowotnej w Polsce w latach 2013–2019
Authors: Politowska-Iwaszko Małgorzata
Published: March 2021

Rozwój i funkcjonowanie publicznej służby zdrowia w sytuacji ograniczonych środków budżetowych wymaga pozyskiwania dodatkowych źródeł finansowania. Działania takie nie powinny skutkować powstawaniem spirali zobowiązań, do której mogą doprowadzić np. kredyty krótkoterminowe. Ważne jest także, aby pozyskane źródło było elastyczne, obciążające budżet w stopniu niższym od korzyści, które można uzyskać dzięki jego uruchomieniu. W gospodarce rynkowej sprawdzonym, dodatkowym źródłem finansowania sektora prywatnego jest leasing. Podobnie jak podmioty prywatne, jednostki publicznej służby zdrowia mogą wykorzystać leasing jako dodatkowe źródło finansowania swojej działalności. W pracy przedstawiono wyniki badania empirycznego przeprowadzonego na próbie czasowej z lat 2013–2019, dotyczącego wykorzystania leasingu przez publiczną służbę zdrowia.

Las pudriciones radicales limitan el rendimiento del frijol (Phaseolus vulgaris), y aunque en Costa Rica son frecuentes, la identidad de los hongos asociados a ellas es incierta. El objetivo de esta investigación fue identificar molecularmente los hongos asociados a las pudriciones radicales y marchitez del frijol en las dos principales zonas productoras del país. Entre 2017 y 2020, se recolectaron 120 plantas en 20 fincas de las regiones Huetar Norte y Brunca. Se muestrearon líneas experimentales (IBC 302-29 y ALS 0536-6) y variedades comerciales (Brunca, Cabécar, Chánguena, Guaymí, Nambí y Tayní). Se describieron los síntomas observados en campo y se efectuaron aislamientos en agar agua rosa de bengala cloranfenicol, luego cultivos puros de punta de hifa en agar agua, que se trasfirieron a papa dextrosa agar para determinar morfotipos con el uso de claves taxonómicas. Los hongos aislados también se identificaron mediante secuenciación de la región ITS del ADN nuclear ribosomal. Se calculó el porcentaje de frecuencia relativa de morfotipos. Los más frecuentes fueron Macrophomina phaseolina (26.7%), Fusarium oxysporum (13.6%) y Athelia rolfsii (5.6%). A partir de los síntomas de marchitez observados en campo se aislaron los hongos comúnmente descritos en frijol para esas patologías. Es necesario realizar pruebas de patogenicidad para confirmar que son los agentes causales.
The Role of Financial Analysis in Mitigating Banking Default " Study on Yemeni Islamic Banks"
Authors: Dr. Zahair Ahmed Ali Ahmed  , Ameen Abdulgaleel Saeed Saeed
Published: March 2021

The study problem was that Yemeni Islamic banks did not rely on the results and outputs of financial analysis to predict failure before it occurs. Accordingly, the study aimed to find out to what extent Yemeni banks depend on financial analysis as a tool for predicting the default, and the extent of its ability to mitigate bank default at these banks. It also aimed to identify whether these banks use all financial analysis tools for making credit decisions. The researchers used the descriptive analytical method and distributed a questionnaire to the sample (50) of the credit employees at Yemeni Islamic banks. The data were analyzed using SPSS. The findings revealed that the Yemeni Islamic banks depend on financial analysis as a basis for disclosure of default, which has a main role in mitigating banking default. The banks usually use multi financial analysis tools when evaluating the credit status of clients; they do not use predicting financial default models as a main tool to predict failure before it occurs; and they do not have early warning systems to predict any possibility of customers’ default.

O envelhecimento favorece algumas mudanças no corpo, o que agrava o estado de saúde e gera riscos de quedas, por isso torna-se importante o estudo das características de idosos com maior risco de quedas. Este estudo procurou comparar as características clínicas, físico-funcionais e laboratoriais de idosos com baixo e alto risco de quedas, classificados pelo teste de Timed up and Go (TUG). Trata-se de um estudo transversal com amostra de conveniência, realizado na Universidade de Maturidade da Universidade Federal do Tocantins. Participaram do estudo 40 idosos que foram submetidos à avaliação da composição corporal, flexibilidade, força de preensão palmar, velocidade de caminhada e exames laboratoriais.  Um ponto de corte de 12,47s no teste TUG classificou os idosos em alto risco de quedas (ARQ) e baixo risco de quedas (BRQ), sendo que, 70% dos idosos foram classificados como BRQ e 30% como ARQ. Os idosos com ARQ são mais velhos, possuem maior gordura corporal e uso de polifarmácia (63%), além de baixa flexibilidade, funcionalidade e força muscular.

Cereal crops, such as oats and barley, possess a number of valuable properties that meet the requirements for functional diet components. This review summarized the available information about bioactive compounds of oat and barley grain. The results of studying the structure and physicochemical properties of the cell wall polysaccharides of barley and oat are presented. The main components of the flavonoids formation pathway are shown and data, concerning anthocyanins biosynthesis in various barley tissues, are discussed. Moreover, we analyzed the available information about structural and regulatory genes of anthocyanin biosynthesis in Hordeum vulgare L. genome, including β-glucan biosynthesis genes in Avena sativa L species. However, there is not enough knowledge about genes responsible for biosynthesis of β-glucans and corresponding enzymes and plant polyphenols. The review also covers contemporary studies about collections of oat and barley genetic resources held by VIR. This review intended to provide information on the processes of biosynthesis of biologically active compounds in cereals that will promote further researches devoted to transcription factors controlling expression of structural genes and their role in other physiological processes in higher plants. Found achievements will allow breeders to create new highly productive varieties with the desirable properties.

Authors: Anastassiou George
Published: March 2021

Here are given tight probabilistic inequalities that provide nearly best estimates for the Csiszar's f-divergence. These use the right and left psi -Hilfer fractional derivatives of the directing function f. Csiszar's f- divergence or the so called Csiszar's discrimination is used as a measure of dependence between two random variables which is a very essential aspect of stochastics, we apply our results there. The Csiszar's discrimination is the most important and general measure for the comparison between two probability measures. We give also other applications.
