Экономические последствия COVID-19 для регионов России
Authors: Коломак Е. А. 
Published: December 2020

<span>В работе исследованы экономические последствия ограничительных мер, вызванных COVID-19, и степень их пространственной неоднородности в России. На основе данных мониторинга социально-экономического положения субъектов Российской Федерации строится индикатор уровня экономической активности регионов в апреле-мае 2020 г. Значимость факторов определялась на основе регрессионного анализа. Тестировались гипотезы, предполагающие, что больше пострадают развитые регионы, крупные города и малый бизнес, учитывалось влияние сокращения спроса на мировых сырьевых рынках. Оценки показали, что экономическая активность в стране после введения ограничений сократилась почти на четверть, запреты имели разные отклики в регионах, степень которых различалась более чем вдвое, однако основная часть предположений не подтвердилась. Городская экономика оказалась более устойчивой к ограничительным мероприятиям по сравнению со средними показателями в стране. Малый бизнес, несмотря на опасения, оказался фактором, поддерживающим экономику регионов. Подтвердилось, что более развитые регионы при прочих равных условиях страдали сильнее. Однако это влияние было перекрыто другими факторами, и ожидаемой тенденции к пространственной конвергенции не наметилось.</span>

Published: December 2020

Considering that today intestinal dysbiosis to some extent affects about 90 % of the population of Ukraine, it is advisable to develop confectionery products with functional ingredients that can affect the microflora and are used to restore the disturbed balance of intestinal ecostructure. Such ingredients include synbiotics. This paper substantiates the need to develop recipes for confectioneries, including marshmallows, to create new types of pastilles with functional properties. Marshmallow production includes the usage of egg whites in fresh, frozen, or dried form as a foaming agent. In recent years, companies use dry egg whites, which have a number of advantages: increasing the sanitary level of production, reducing production area, improving safety and quality stability of finished products that included it in the formula. The functional and technological properties of dry egg whites have been studied regarding the possibility of obtaining pastille products with high-quality stable foam structure. It has been experimentally established that dry protein should be reduced at 30…40 °C and the optimal foaming ability of the protein is at 40…45 °C. The regularities of the foaming process in confectionery masses with a synbiotic have been determined. It has been found that the marshmallow mass with microencapsulated bifidobacteria and lactulose (5; 7.5; and 10 %) requires 6, 5 and 4 minutes of whisking at 400 rpm to form foam, respectively, whereas the control sample required 8 minutes. The dependence of quality indicators of marshmallow masses (density and air volume concentration) on the foaming temperature has been studied. It has been established that the production of marshmallow mass with a synbiotic of a certain density occurs at 38 °C and the study of air volume concentration confirms that the maximum temperature allowing to produce a high-quality mass is 40 °C. Thus, the whisking temperature required to obtain high-quality and stable foam has been experimentally determined for the marshmallow mass. This research allows us to state with confidence that introducing a synbiotic complex into the structure of a marshmallow mass improves the foaming process which allows to produce high-quality products with soft texture and stable foam structure.

Published: December 2020

One of the most significant current discussions in fluid transport industry is how to prolong the service life of a metallic pipeline system under severe physical and chemical conditions. Electrochemical corrosion is a persistent problem, causing material degradation and sometimes resulting in serious consequences. Here more than 150 three-point bending tests were done on 82 corroded carbon steel pipes to examine their remaining strength. The current work proposes an artificial protocol to accelerate the electrochemical corrosion of ferrous tubes in a controllable system and analyzed correlations between removed iron mass, the depth of corroded sites, and the deterioration in the mechanical properties of the sample pipes. Based on these correlations, a rough estimate for the retirement life of pipelines is put forward as a referable option.

Published: December 2020

On the basis of the one-dimensional theory of calculating the operation of steam turbine stages the method for determining the idle mode, the initial data for which are the geometric characteristics of the blade rows is proposed. Formulas have been obtained that make it possible to calculate the efficiency in the proximity of Rotor Blades (RB) at operating modes from nominal to the idle mode, depending on the flow rate of the stage and taking into account the use of kinetic energy with the runaway velocity and losses arising at off-design angles of flow on the Rotor Blade (RB). The results of possible computational studies and their comparison for an incompressible working fluid with the results of experimental studies showed the good possibilities of the proposed method for determining the idle mode in a wide range of the characteristics of stages.

BackgroundEndometrial cancer (EC) is one of the most common gynecological cancers. Epithelial–mesenchymal transition (EMT) is believed to be significantly associated with the malignant progression of tumors. However, there is no relevant study on the relationship between EMT-related gene (ERG) signatures and the prognosis of EC patients.MethodsWe extracted the mRNA expression profiles of 543 tumor and 23 normal tissues from The Cancer Genome Atlas database. Then, we selected differentially expressed ERGs (DEERGs) among these mRNAs. Next, univariate and multivariate Cox regression analyses were performed to select the ERGs with predictive ability for the prognosis of EC patients. In addition, risk score models were constructed based on the selected genes to predict patients’ overall survival (OS), progression-free survival (PFS), and disease-free survival (DFS). Finally, nomograms were constructed to estimate the OS and PFS of EC patients, and pan-cancer analysis was performed to further analyze the functions of a certain gene.ResultsSix OS-, ten PFS-, and five DFS-related ERGs were obtained. By constructing the prognostic risk score model, we found that the OS, PFS, and DFS of the high-risk group were notably poorer. Last, we found that AQP5 appeared in all three gene signatures, and through pan-cancer analysis, it was also found to play an important role in immunity in lower grade glioma (LGG), which may contribute to the poor prognosis of LGG patients.ConclusionsWe constructed ERG signatures to predict the prognosis of EC patients using bioinformatics methods. Our findings provide a thorough understanding of the effect of EMT in patients with EC and provide new targets and ideas for individualized treatment, which has important clinical significance.

Objective: Patients with hypochondriasis hold unexplainable beliefs and a fear of having a lethal disease, with poor compliances and treatment response to psychotropic drugs. Although several studies have demonstrated that patients with hypochondriasis demonstrate abnormalities in brain structure and function, gray matter volume (GMV) and functional connectivity (FC) in hypochondriasis still remain unclear.Methods: The present study collected T1-weighted and resting-state functional magnetic resonance images from 21 hypochondriasis patients and 22 well-matched healthy controls (HCs). We first analyzed the difference in the GMV between the two groups. We then used the regions showing a difference in GMV between two groups as seeds to perform functional connectivity (FC) analysis. Finally, a support vector machine (SVM) was applied to the imaging data to distinguish hypochondriasis patients from HCs.Results: Compared with the HCs, the hypochondriasis group showed decreased GMV in the left precuneus, and increased GMV in the left medial frontal gyrus. FC analyses revealed decreased FC between the left medial frontal gyrus and cuneus, and between the left precuneus and cuneus. A combination of both GMV and FC in the left precuneus, medial frontal gyrus, and cuneus was able to discriminate the hypochondriasis patients from HCs with a sensitivity of 0.98, specificity of 0.93, and accuracy of 0.95.Conclusion: Our study suggests that smaller left precuneus volumes and decreased FC between the left precuneus and cuneus seem to play an important role of hypochondriasis. Future studies are needed to confirm whether this finding is generalizable to patients with hypochondriasis.

The problem connected with the methodology of research on old binders remains unsolved. The reason of this situation raises from the impossibility of creating one formula according to which all old binders ally known. One might think that a simultaneous use of all the methods for research on binders coming from historical objects would guarantee complete information on the binders. At the same time the information would be helpful in restoration process, especially those of reconstruction would in the identifying of the causes of damages. A considerable difficulty with talking samples is an additional problem. This refers first of all to plasters located below paintings, where the possibility of talking samples is very limited because of a possible damaging of the painting. It is especially do research which will provide maximum information, because after carrying out restoration works many marks may be impossible to remake. Therefore making a decision on the type of research one should find such information which will provide the line of further research. The introductory information may be collected through the observation of thin sections in transmitted light with a polarizing microscope. An analysis analogous to that which is done at the identification of rocks–petrography analysis.

Authors: Herandez -Trujillo Sergio , Esqueda Escárcega Gabriela Ma. 
Published: December 2020

Estimates of secondary production through indicators from pelagic copepods under laboratory conditions were carried out in Mexican waters of the eastern tropical Pacific. Copepods were collected during April 2015, separated and in three oceanographic stations off the coast of Guerrero, Mexico. Only Labidocera acutifrons, Subeucalanus pileatus and Centropages furcatus presented reproductive activity. Secondary production indicators were the rate of egg production (TPH), the mass-length relationship and condition factor. The species with the highest TPH and the highest value of condition factor (K) was Labidocera acutifrons. In all three species allometric growth was observed. This is the first estimate of secondary production for zooplankton in the Mexican Central Pacific. Thus it should be extended to a larger number of taxa and for a wider seasonal space-time scale

This research aims to findout the influence of transformational leadership and motivation to excel on teacher teaching performance at Dirgantara Senior High School Center. The population in the study was teachers at SMA Dirgantara Center which numbered 34 teachers, while the sample determination technique was. So the sample in this study was 34 people. This type of research is quantitative research. Quantitative research is a study that aims to find out the degree of relationship and pattern/form of influence between two or more variables, where by this research will be built a theory that serves to explain, predict and control a symptom. As for the data sources in this study from primary data and secondary data. Where is the primary data from observations, interviews and questionnaires? While secondary data can be from documented data.
Test results (t) or partial tests show that transformational leadership has a positive and significant effect on teacher teaching performance as well as motivational variables that also have a positive and significant effect on teacher teaching performance. Simultaneously transformational leadership and motivation of achievement havea positive and significant impact on the teaching performance of teachers. The result of determination is obtained a correlation regression value of 0.770, meaning that together transformational leadership and motivation to excel against the teaching performance of teachers at SMA Dirgantara Center has contributed to a close and positive level. Then the determination coefficient (R2) is 0.566 (56.6%). So it can be said that 56.6% variation of bound variables i.e. transformational leadership and motivation to excel on the model has a contribution to teacher teaching performance at SMA Dirgantara Center while the remaining 43.4% is influenced by other variables outside the model.
