Based on previous theoretical studies, the main design parameters of the device were established, such as angle of installation of wire screens, the number of wire screens in hopper, the location of wire screens in hopper, and the minimum size of the gap and bridge in wire screens. It is established that in order to determine the optimal width of the gap in the wire screen, it is necessary to know the height of bulk material layer passing through the gap of the hopper device element and speed of bulk material on the second bridge. To ensure optimal operation of the element (wire screen) of the device for controlling technological process of loading, storage and unloading, it is necessary that loaded material passes evenly through the wire screen that is throughput capacity of each slot of the device is the same. The obtained equations allow us to determine the minimum gap width depending on the radius of bulk material particle, falling speed of the material on the screen, coefficient of friction and width of crossbar of the screen. For experimental research, a laboratory model of a bunker-type device was created and tested. The model allows you to quickly change parameters such as the angle of inclination of wire screen, gap width in the wire screen, the length of the wire screen, the distance between the wire screens and the height of the loaded layer. At the same time, it was found that the loading process is influenced by the coefficients of uniformity of distribution of bulk material over the entire cross-section of container, as well as the coefficient of material segregation when filling the loading device. The method of conducting experiments included determining the parameters of developed hopper device: the angle of inclination of the wire screen, the length of the wire screen, gap width in the screen and the interval between the sieves. The initial levels were selected based on analysis of previous studies of the bulk material loading process. The results of these studies identified the optimal values of main parameters of the developed device depending on the downloadable material: the angle of inclination of wire screen - 36...38°; length of wire screen...0,19 0,28 m; the distance between screens - 2,3...2,8 m. The obtained numerical values of parameters can be used in the design of bunkers or silos for similar purposes.

Published: November 2020

The research was carried out on the experimental field of FSBEI HE Ulyanovsk SAU in 2017-2019. The purpose of the research was to identify the influence of agroclimatic conditions in the region on the formation of yield and quality of winter wheat grain Saratovskaya 17 against various doses of mineral fertilizers. The experience scheme provided 4 options: 1. Control (without fertilizers); 2. N20P20K20; 3. N40P40K40; 4. N60P60K60. It was found that precipitation during the resumption of vegetation-flowering had a significant impact on the yield of winter wheat grain (R2=0,78). To characterize the humidification of the territory, hydrothermal coefficient was calculated according to G. T. Selyaninov. In 2019, it was 0.21, which characterizes the period as very dry. In 2017 and 2018 weather conditions for winter wheat were more favorable (SCC 0.92 and 0.75-insufficiently moist). An increase in yield was observed at a SCC of 0.92 (2017) in all variants of the experiment. The correlation coefficient between the yield of the studied crop and the SCC indicator was 0.84, which indicates a significant dependence of winter wheat productivity on hydrothermal conditions that develop during the period from the resumption of vegetation to flowering of the crop. It is important to note that the main factor affecting the accumulation of gluten in winter wheat grain Saratovskaya 17 and changes in its elastic-elastic properties are the conditions of mineral nutrition of plants. The coefficient of determination shows that 60% of the gluten quality was determined by the conditions of plant nutrition and did not depend on the prevailing weather conditions.

Authors:   FSBEI HE Don state agrarian university, Ryabtseva N. А.
Published: November 2020

In the article we show arguments for achieving the research goal- to get economically feasible crop yield growth of sunflower , spring barley and winter wheat in zone of low moisture of Rostov region against common and soil protective technology. The experiment was two-factorial: factor А – crop rotation link, factor B – crop cultivation technology. Soil protective technology with after harvesting and plant residues on soil surface affected moisture collection and conservation in soil at the cost of best preservation of snow cover, decrease of aeration. Soil protective technology allowed to preserve in the field from 84,5 to 95,1 % of plant residues, which increased show cover for 16,5-28,4%. Significant impact on soil density soil protective technology didn’t demonstrate. Compared to common, it helped to increase the number of earthworms in 4,3 times, which is the evidence of environmentally safe soil quality. Influence of soil protective technology on field emergence of studied cultures is established. Survival of cereal crops was higher for 2-5 %, and sunflower was lower for 5,4 %. All the cultures increased crop yield when using soil protective technology. Effect of transition to soil protective technology grew from year to year. Profitability raised in the first year for 11%, in the second for 13%, in the third for 36%. Spring barley and sunflower showed big response on this technology. Introduction of soil protective technology in average in years of experiments improved profitability for 20 %.

The aim of the study is to search for new sources of resistance to stinking smut among the ITMI population lines. The article presents analysis of data on the study of reaction of spring soft wheat, which is resistant to stinking smut, to the introduction of pathogen. The experimental part of the work was carried out in 2016-2018 on an infectious background of a phyto-stage in the conditions of the forest-steppe of the Middle Volga region (Samara ARI-branch of SamRC RAS, Bezenchuk country). 77 lines of ITMI mapping population were used as objects, as well as a population of Tilletia caries pathogen collected from zoned and susceptible varieties. In the experiment, healthy seeds (control) and seeds infected with pathogen were sown. For inoculation of wheat seeds with this pathogen, the A. I. Borggardt-Anpilogov method was used. Cleaning was carried out manually, by cutting plants from the plot in the phase of full ripeness. Accounting for damage to samples of stinking smut was carried out in the phase of milk-wax stage of the grain, carefully viewing and counting all the spikes on the plot. A five-grade scale created by V. I. Krivchenko was used for classing the samples resistance to stinking smut. Weather conditions in the years of research were different, but developed mainly favorable for creating an infectious background, as well as for the growth of spring wheat plants. 4 lines had immunity (ITMI-40, 75, 90, 91). Practical stability was observed on 5 lines (damage from 4.3 to 10.0%). 8 lines were poorly susceptible (the maximum lesion was 21.0%). With an average susceptibility, 21 lines were isolated, the remaining lines were mostly affected by more than 50%. Selected samples can serve as a valuable source material for use in immunological breeding programs.

Published: November 2020

Although there have been many studies on the effects of electromagnetic fields on humans, scientists still have no agreement on the effects found because several studies showed no statistically significant effects. The effects of radiofrequency electromagnetic fields exposure on the immune system are varied, ranging from no effects to genotoxic effects on lymphocytes. Our study aimed to investigate whether exposure to 1800 MHz radiofrequency electromagnetic fields (RF-EMF) in variable durations and distances could lead to the dysregulation of T helper 1, 2, and 17. The peripheral blood mononuclear cells (PBMCs) cultures from healthy human subjects were exposed to 1800 MHz RF-EMF, with durations of 15, 30, 45, and 60 minutes and distances of 5 and 25 cm. We evaluated the effects of RF-EMF exposure on the number of CD4+ T cells, IL-2, IL-10, and IL-17a after 48 hours of culture with the flow cytometer. The closer the distance, the lower the number of CD4+ T cells. The longer the exposure, the lower the number of CD4+ T cells and the number of IL-2, IL-10, and IL-17a decreases significantly. CD4+ T cells expressing IL-2 increased significantly with the increase of the duration of 1800 MHz RF-EMF exposure (15, 30, and 45 min), but decreased at 60 minutes of exposure when compared to PBMCs without exposure. Sixty minutes of PBMC exposure to RF-EMF with a distance of 5 cm causes a significant reduction in the number of CD4+ T cells, the expression of IL-2, IL-10, and IL-17a.

Bayesian Joint Modeling of Skew-Positive Longitudinal-Survival Data Using Birnbaum-Saunders Distribution
Authors: Jafari-Koshki Tohid , Hosseini Sayed Mohsen , Arsang-Jang Shahram
Published: November 2020

Background: There has been a great interest in joint modeling of longitudinal and survival data in recent two decades. Joint models have less restrictive assumptions in multivariate modeling and could address various research questions. This has led to their wide applications in practice. However, earlier models had normality assumption on the distribution in longitudinal part that is usually violated in real data. Hence, recent research have focused on circumventing this issue. Using various skewed distributions has been proposed and applied in the literature. Nevertheless, the flexibility of the proposed methods is limited especially when the data are skew positive.
Methods: In this paper, we introduce the use of Birnbaum-Saunders (BS) distribution in joint modeling context. BS distribution is more flexible and could cover a wide range of skew, kurtotic or bimodal data.
Results: We analyzed publicly available ddI/ddC data both with normal and BS distributions in Bayesian setting and compared their fit by Widely Applicable Information Criterion (WAIC). The joint BS model showed a better fit to the data.
Conclusion: We introduced and applied BS distribution in joint modeling of longitudinal-survival data. Using multi-parameter distributions such as BS in Bayesian setting could improve the fit of models without limitations that arise in transformation of data from original scale.

Authors: Sule Ibrahim , Ibrahim Doguwa Sani , Isah Audu , Muhammad Jibril Haruna
Published: November 2020

Background: In the last few years, statisticians have introduced new generated families of univariate distributions. These new generators are obtained by adding one or more extra shape parameters to the underlying distribution to get more flexibility in fitting data in different areas such as medical sciences, economics, finance and environmental sciences. The addition of parameter(s) has been proven useful in exploring tail properties and also for improving the goodness-of-fit of the family of distributions under study.
Methods: A new three-parameter family of distributions was introduced by using the idea of T-X methodology. Some statistical properties of the new family were derived and studied.
Results: A new Topp Leone Kumaraswamy-G family of distributions was introduced. Two special sub-models, that is, the Topp Leone Kumaraswamy exponential distribution and Topp Leone Kumaraswamy log-logistic distribution were investigated. Two real data sets were used to assess the flexibility of the sub-models.
Conclusion: The results suggest that the two sub-models performed better than their competitors.

Published: November 2020

Background: Over the past years, there has been a great deal of interest in applying statistical machine learning methods to survival analysis. Ensemble-based methods, especially random survival forest, have been developed in various fields, especially medical sciences, due to their high accuracy and non-parametric nature and applicability in high-dimensional data sets. This paper aims to provide a methodological review and how to use random survival forests in the analysis of right-censored survival data.
Method: We present a review article based on the latest research in the PubMed database on random survival forest model methodology.
Results: This article begins with an introduction to tree-based methods, ensemble algorithms, and random forest (RF) method, followed by random survival forest framework, bootstrapped data and out-of-bag (OOB) ensemble estimators, review of performance evaluation indicators, how to select important variables, and other advanced topics of random survival forests for time-to-event data.
Conclusion: When analyzing right-censored survival data with high-dimensional data, while the relationships between variables are complex and their interactions are taken into account, the nonparametric random survival forest (RSF) method determines important variables affecting survival times with high accuracy and speed and also does not need to test the restrictive assumptions.

Published: November 2020

Aim: Many studies have showed that myalgia is a common onset symptom in coronavirus disease 2019 (COVID-19). This study aimed to determine the frequency of muscle pain in patients followed with COVID-19 diagnosis, and to investigate the relationship between muscle pain and creatine kinase (CK), pH, lactate and lactate dehydrogenase (LDH) levels.

Material and Methods: One hundred ten patients diagnosed with COVID-19 in our hospital were included retrospectively in this study. Presence of myalgia at the time of admission and on the 14th day of control were investigated. The first admission laboratory findings, 3rd day CK values and 14th day control CK values of all patients were recorded retrospectively from their files.

Results: The study included 110 patients diagnosed with COVID-19. Fifty patients (45.5%) had muscle pain at the time of admission, and it was one of the most common musculoskeletal complaints. High CK results were obtained in 48 (43.6%) of the 110 patients at the time of admission. Thirty-two (66.7%) of 48 patients with high CK had muscle pain (p

Phenotypic and genotypic variations within the genus Sambucus are limited. They could be efficiently increased by genetic recombination involving different species. The aim of the presented investigation was to assess the possibility of using molecular approach (i.e., microsattelites) in determination of unknown hybrid structures. The study involved 47 Sambucus genotypes (parental species and intespecific hybrids), and six microsatellite loci were analysed. The clustering method grouped the analysed genotypes into four main groups. The first main group involved two sub-groups: one with taxons and hybrids involving S. racemosa (in broad sense) and the other involving two botanical varieties of S. nigra. In the second main group, there was a sub-group involving hybrids between S. javanica and S. nigra, and a sub-group involving F1 hybrids between S. javanica and S. ebulus. The third main group contained a sub-group with hybrids between S. javanica and S. nigra ‘Black Beauty’, a sub-group with hybrids involving S. javanica, S. nigra and S. racemosa (miquelii), a sub-group with backcrosses S. javanica × (S. javanica × S. ebulus), and un unknown hybrid. The fourth main group included a subgroup with F1 hybrids S. javanica × S. ebulus, a sub-group involving various taxons of S. racemosa (in broad sense), and a sub-group involving hybrids between S. cerulea and S. javanica, with and without S. nigra. Our study shows that molecular analysis can be helpful in determining some of the unknown but simple interspecific hybrids of Sambucus. In the cases of complex hybrid combinations, the use of SSRs is most probably not the best solution.

Актуальность исследования экзогенных процессов, в том числе дефляции, обусловлена как положительным, так и отрицательным воздействием их на природные компоненты и хозяйственную деятельность человека. Кроме того, не до конца выявлены особенности региональной миграции вещества при развитии этих процессов и интенсивность аккумуляции эолового наноса, его вещественный состав. Изучение факторов развития эрозии и дефляции в геосистемах юго-востока Томской области показало, что природные и социально-экономические факторы региона благоприятны для развития эоловых процессов. Цель: оценка интенсивности аккумуляции эолового осадка и его вещественного состава в ландшафтах юго-востока Томской области. Объекты: природные и антропогенные комплексы Томь-Яйского междуречья в пределах бассейна р. Басандайки – правого притока р. Томи. Методы: полевые (маршрутные) наблюдения с отбором проб, лабораторные и аналитические исследования. Результаты многолетних наблюдений показали, что в холодный период года эоловые процессы в агроландшафтах юго-востока лесной зоны Западно-Сибирской равнины проявляются ежегодно, но с разной степенью интенсивности. Наиболее активно они развиваются в малоснежные годы. В гранулометрическом составе эолового наноса преобладает пыль, в минералогическом – кварц и мусковит. Эоловые отложения содержат значительное количество элементов питания растений – гумуса – до 10 %. Не исключая притока атмосферных выпадений из других регионов, считаем, что основная масса эолового осадка ключевых участков (юго-восток Томской области) в холодное время года имеет местное происхождение, об этом свидетельствует большое сходство его гранулометрического, химического и минералогического состава с почвами региона.
Clown in the City
Authors: de Beer Stephan
Published: November 2020

At opening this book, everything one has learned or thought about “urban ministry” is challenged, and changed. Stephan de Beer offers a fresh, exciting and thoroughly engaging approach. The title is enticing and playful, but the book is a serious grappling with the daunting realities of a shadowed, marginalised, urban life. It does not theorise or pontificate about a concept. The author is not a distant, neutral observer. He is an engaged minister to the people, a struggler in their struggles, prophet to the powerful. This book invites the reader to join the people of the cities under siege by failed policies, empty promises, and disastrous politics, in their struggles for meaningful life, and it makes a powerful, persuasive case. Stephan de Beer has offered us a great gift and a wonderful opportunity to think and hope anew, and differently, about the life, reality, and future of the city.
Lactation Care of Families in the Community Health Setting During the COVID Pandemic
Authors: Altman Denise
Published: November 2020

Background

The COVID pandemic challenged IBCLCs and other heathcare providers to determine how to meet the needs of new families while maintaining safety for both patients and caregivers. In addition, both workplace and personal stressors triggered by ongoing changes increased the risk of compassion fatigue.

Program

Initial patient support was offered at a free-standing lactation medicine clinic. After office closure, lactation services moved to multiple pediatric offices.

Result

Although the worksite changed after the first six weeks of the pandemic, direct patient care providing lactation support remained uninterrupted, and continues to this day. The IBCLCs are addressing the issue of compassion fatigue with awareness along with peer to peer support.

Abstract

As a political communicator, members of the DPR RI need to realize good political communication for the sake of the continuation of democracy. The Indonesian Parliament as a political actor that has an important role in the sustainability of democracy needs to manage their political communication from the front stage, back stage, and impression management aspects according to Goffman's theory as well as possible. In this study, it was examined how the political communication of the Indonesian Parliament in revising Law No. 32 of 2002 using the Goffman drama theory. The method used in this research is qualitative research using observation data collection techniques to three groups of the Republic of Indonesia DPR. From this dramaturgical analysis the researchers found that DPR groups had three front stages and one backstage each. Also found was a shadowing stage faced by the DPR in carrying out political communication activities. Political communication behavior carried out at the front stage is more formal and prioritizes the interests of the community. As is the case at the back stage, political communication is more relaxed and personal and group interests emerge.

Abstrak

Sebagai komunikator politik, anggota DPR RI perlu mewujudkan komunikasi politik yang baik demi kelangsungan demokrasi. DPR RI sebagai aktor politik yang memiliki peran penting dalam keberlangsungan demokrasi perlu mengelola komunikasi politik mereka dari aspek front stage, back stage, serta impression management sesuai dengan teori Goffman sebaik mungkin. Dalam penelitian ini diteliti bagaimana komunikasi politik DPR RI dalam melakukan revisi UU No. 32 tahun 2002 dengan menggunakan teori dramatugri Goffman. Metode yang digunakan dalam penelitian ini ialah penelitian kualitatif menggunakan teknik pengumpulan data observasi kepada tiga kelompok DPR RI. Dari analisis dramaturgi ini peneliti menemukan temuan bahwa kelompok-kelompok DPR memiliki masing-masing tiga pangung depan dan satu panggung belakang. Ditemukan juga panggung bayangan yang dihadapi oleh DPR dalam menjalankan kegiatan komunikasi politik. Perilaku komunikasi politik yang dilakukan pada front stage bersifat lebih formal dan mengutamakan kepentingan masyarakat. Lain halnya dengan yang dilakukan pada back stage, komunikasi politik bersifat lebih santai dan muncul kepentingan-kepentingan pribadi maupun kelompok.

Self-Quantification Systems to Support Physical Activity: From Theory to Implementation Principles
Authors: Dulaud Paul , Di Loreto Ines , Mottet Denis
Published: November 2020

Since the emergence of the quantified self movement, users aim at health behavior change, but only those who are sufficiently motivated and competent with the tools will succeed. Our literature review shows that theoretical models for quantified self exist but they are too abstract to guide the design of effective user support systems. Here, we propose principles linking theory and implementation to arrive at a hierarchical model for an adaptable and personalized self-quantification system for physical activity support. We show that such a modeling approach should include a multi-factors user model (activity, context, personality, motivation), a hierarchy of multiple time scales (week, day, hour), and a multi-criteria decision analysis (user activity preference, user measured activity, external parameters). While implementation still poses many challenges, principles linking theory to implementation should facilitate the design of effective self-quantification systems. In this way, users who wish to improve their physical activity levels could be better supported.

Electrical remodelling as a result of the homeodomain transcription factor 2 (Pitx2)‐dependent gene regulation was linked to atrial fibrillation (AF) and AF patients with single nucleotide polymorphisms at chromosome 4q25 responded favorably to Class I antiarrhythmic drugs (AADs). The possible reasons behind this remain elusive. The purpose of this study was to assess the efficacy of AADs disopyramide, quinidine, and propafenone on human atrial arrhythmias mediated by Pitx2-induced remodelling, from a single cell to the tissue level, using drug binding models with multi-channel pharmacology. Experimentally calibrated populations of human atrial action potential (AP) models in both sinus rhythm (SR) and Pitx2-induced AF conditions were constructed by using two distinct models to represent morphological subtypes of AP. Multi-channel pharmacological effects of disopyramide, quinidine, and propafenone on ionic currents were considered. Simulated results showed that Pitx2-induced remodelling increased maximum upstroke velocity (dVdtmax) and conduction velocity (CV), and decreased AP duration (APD) and wavelength (WL). At the concentrations tested in this study, these AADs decreased dVdtmax and CV and prolonged APD in the setting of Pitx2-induced AF. Our findings of alterations in WL indicated that quinidine and disopyramide may be more effective against Pitx2-induced AF than propafenone by prolonging WL.
