Resumo: O presente trabalho teve como objetivo a determinação dos parâmetros ótimos do processo de manufatura aditiva de Fusão Seletiva a Laser (FSL) para o aço 316L visando a obtenção de peças com alta densidade, utilizando equipamento fabricado no Brasil. Foi realizada também uma completa caracterização estrutural tanto da matéria prima utilizada (pó comercial) quanto das peças mais densas obtidas. As propriedades mecânicas das peças produzidas por FSL também foram avaliadas e comparadas com peça fabricada de forma convencional. Foi observado que a densidade das peças aumenta com o aumento da densidade volumétrica de energia fornecida pelo laser até atingir um patamar de máxima densidade. Um modelo polinomial foi proposto correlacionando a densidade volumétrica de energia utilizada com a densidade final da peça. As peças produzidas por FSL mostraram uma elevada densificação (densidade relativa superior a 99,49%) com uma reduzida porosidade homogeneamente dispersa no material. Uma microestrutura austenítica celular, típica do processo FSL, foi obtida. A dureza e a microestrutura das peças se mostrou constante ao longo do comprimento das mesmas e os resultados obtidos em ensaio de compressão mostraram que as peças obtidas por FSL possuem uma resistência mecânica e ductilidade próximas às observadas para amostra fabricada de forma convencional.

Authors: Dias Ana Paula de Melo , Vieira Ellen da Fonseca , Gomes Elisete Ribeiro
Published: September 2020

A Atenção Primária à Saúde (APS) é um cenário capaz de produzir cuidado em todas as fases da vida, desde o nascer ao morrer. Porém, o cuidado de saúde de pessoas gravemente enfermas requer uma abordagem complexa e holística desses sujeitos e famílias, sendo muitas vezes prestado em domicílio. Uma das atribuições relacionadas aos cuidados em fim de vida é a emissão da declaração de óbito quando este ocorre em domicílio. Pela perspectiva de uma médica de Família e Comunidade, relatou-se, de modo narrativo e reflexivo, uma experiência de um atendimento domiciliar para emissão de declaração de óbito. A partir dessa narrativa, discutiu-se sobre como a visita para declaração de óbito nos convida a entrar em um território repleto de subjetividades, que nos evoca muitas reflexões sobre o processo de morte e morrer, provocando transformações em nossa vida pessoal e profissional.

Published: September 2020

Abstract A histopathological survey was conducted to investigate the presence of microparasites in fish Archosargus probatocephalus in a river near Maceió, Brazil. Light microscope observations of fragments of gill showed the presence of small cysts containing numerous myxospores that were morphologically identified as Henneguya. Transmission electron microscopy observations further revealed several gill cells containing groups of prokaryotic cells within large cytoplasmic vacuoles. Each infected host cell displayed a single vacuole containing a variable number of Rickettsia-like cells (up to 11), some of which presented the dumbbell shape characteristic of binary fission. The Rickettsia-like cells were pleomorphic, without a nucleus and with chromatin dispersed in the cytoplasm. They had a thin electron-dense wall of Gram-negative type. The morphology of these prokaryotic was similar to those of the order Rickettsiales and was described as a Rickettsia-like organism. Histopathological evaluation showed that several vacuole membranes had a lysed appearance. Some had ruptured, thus allowing direct contact between the Rickettsia-like organism and the cytoplasm of the host cell. The rupturing of the branchial epithelium may have contributed towards reduction of the surface area of the gills, but it is not possible to say that this was the cause of the host’s death.

Published: September 2020

Safflower is a conspicuous energy crop might be used as a biofuel and raw material source for vegetable oil and animal feed sectors. It has a potential to reduce energy and oil dependency of Turkey reached to a high level due to its capacity. Weeds can cause yield loss because they compete with the crop for water, light, space, and nutrients in safflower. Weed control practices, therefore, should be made efficiently to gain high safflower yield. The aim of this study is to determine the efficacy of pendimethalin, s-metolachlor, and chlorsulfuron to control weeds and the response of safflower to them. The field experiments were conducted during 2017-2019 in Gölbaşı, Ankara, Turkey. Pendimethalin and s-metolachlor were applied to the soil surface before crop sowing at 675.0, 1012.5, 1350 and 2700, and 686.25, 915.0, 1372.5 and 2745.0 g active ingredient (ai) ha-1, respectively. Chlorsulfuron was treated at 3.75, 4.95, 5.625, 7.5 and 15.0 g ai ha-1 to the weeds when they were 2-4 true leaf stage. Responses of safflower to the herbicides and the efficacy of these herbicides on the weed were visually evaluated 14 and 28 days after treatment (DAT) and before the harvest. Pendimethalin caused very slight crop injury, and the symptoms were disappeared at 28 DAT in 2017, but same symptoms were not observed in 2018. The crop injury caused by chlorsulfuron was transient when it was applied lower than at 5.625 g ai ha-1; however, chlorsulfuron at 7.5 and 15 g ai ha-1 injured persistently safflower plants. Pendimethalin provided moderate control on wild mustard and redroot pigweed at 1350 g ai ha-1 while s-metolachlor at 1372.5 g ai ha-1 sufficiently controlled redroot pigweeds, but not wild mustard. Weed control with chlorsulfuron at higher than 4.95 g ai ha-1 was good compared to lower rates.

Published: September 2020

Development of regional situational centres in the Russian Federation is one of the priority trends of digitalization which leads the organization of state management to a new level. Integration of such centres into a unified system of distributed situational centers will allow performing monitoring of social, economic and ecological spheres both locally and in the whole country which increases the efficiency of state management. The main difference of the situational centres of the new generation is the development of analytical unit which exploits the opportunities of economic and mathematical and computer modeling of social processes in the systems for maintaining of management decisions. Modern systems for maintaining of management decisions are able to maintain search and visualization of data and can be used for estimating the consequences of implementation of management decisions planned. Thus, within the regional situational centre it is possible to create a polygon for approbating management decisions and choosing the most appropriate options. The authors introduce the concept of agent-oriented social ecological economical model as a digital analogue of the Kemerovo region. The model is assigned for making computer experiments on forecasting social-economic and ecological indexes of the region under different conditions of outer environment and during realization of different projects. The tool can be developed further on depending on the region’s specificity and the current tasks of the local authorities.

Published: September 2020

Governmental support in the formation of economic and intellectual potential of Kuzbass contributes to more comfortable conditions for development of business and improvement of life quality of the population. Strategic branding tools are an effective mechanism which allows building up long-term and trusting relationship with the local people and introducing certain values. The effect of external shocks including the COVID-19 pandemics on the functioning of social and economic spheres also reveal the necessity of their structural transformation and the need for raising digitalization level. The authors of the article suggest a number of strategic initiatives aimed at improving the business reputation of Kuzbass. Kuzbass Trading House can become a centre for promoting Russian hi-tech companies abroad, presenting investment projects. It also can act as an integrator of international engineering projects and a driver for technology transfer. As digitalization tends to spread wider and wider the authors suggest creating an electronic platform «KuzbassTrade» to improve the performance of Kuzbass Trading Centre and build the financial stability of the region. The platform will function as a virtual presentation of products, services and technologies of local representatives of corporate and scientific sectors. State institution «Agency for Investments Attraction and Protection» and leading higher educational institutions and research organizations of Kuzbass should strategically take direct part in creating a unified chain for determining innovative technologies to be implemented (including patent landscape and market niche analysis) and form investment package offers for building new manufactures and consortiums.
Conocimiento tradicional campesino, una posibilidad de visualizar lo rural a propósito de la enseñanza de la biología en contexto
Authors: Pacheco Calderón Diana
Published: September 2020

Indagar por los conocimientos tradicionales campesinos a través de la recuperación de la memoria biocultural, la experiencia del maestro que trabaja en el entorno rural en Colombia y el lugar que ocupa la enseñanza de la Biología en este contexto, se convierte en una posibilidad de problematizar y reflexionar en torno al panorama de tensiones y complejidades que se dan desde las formas de pensar, actuar y habitar la vida rural, en el cual se ve una necesidad imperante de cuidar la vida, no solo la humana, sino la de los otros seres vivos. En este sentido, se pretende hacer visible la importancia del empoderamiento del rol político que tiene el sujeto maestro y la posibilidad de visualizar lo rural desde abordajes del conocimiento con una perspectiva transdisciplinar, en aras de crear ambientes de aprendizaje que fomenten prácticas para el cuidado de la vida desde diálogos de conocimientos entre la Biología y las comunidades rurales que permitan la reconstrucción del carácter pedagógico del concepto Vida.
Matemos al bicho: la huerta escolar como escenario educativo para la argumentación y la toma de decisiones
Authors: Guerrero Gerardo Juan , Peñaloza Gonzalo
Published: September 2020

El huerto escolar ha sido una estrategia ampliamente utilizada como recurso didáctico para la enseñanza de la biología y para la educación ambiental. Este artículo de investigación explora las posibilidades de dicho escenario educativo para plantear dilemas éticos y ambientales en los que se relacionan intereses y beneficios, y que implican decisiones sobre la vida y la muerte de un organismo. Para esto se llevó a cabo una investigación con estudiantes de los grados tercero (n = 21) y sexto (n = 42) de educación básica, quienes se involucraron en el cultivo de una huerta y en discusiones sobre dilemas en torno a la conservación o erradicación de un insecto en la huerta. A través de las justificaciones de sus decisiones, se evidencian las posibilidades que tiene este escenario para el desarrollo de las habilidades argumentativas y de toma de decisiones. Los hallazgos sugieren que los estudiantes privilegian el dominio afectivo sobre el cognitivo en sus justificaciones, es decir, que los estudiantes no incluyen frecuentemente conceptos biológicos en las razones que son parte de sus argumentos.

Authors: İLHAN Aziz , ASLANER Recep
Published: September 2020

In the study, the correlations between visual mathematics literacy perceptions, reasoning skills on geometrical shapes and geometrical performances of pre-service mathematics teachers were investigated. The study participants included 384 pre-service mathematics teachers, who were attending education departments in two universities located in Eastern and Southeastern Anatolia regions in Turkey. In the study, due to time and workforce limitations, convenience sampling method was preferred, and relational screening model was adopted. The study data was collected with visual mathematics literacy perception scale, reasoning skills on geometric shapes and geometry performance tests developed by the authors. Analysis of the correlation between the variables demonstrated that there was a moderate correlation between visual mathematics literacy perception and both the reasoning skills on geometrical shapes and the geometry performance, and there was a high correlation between the reasoning skills on geometric shapes and geometry performance. Primary model path analysis demonstrated that visual mathematics literacy perception had a moderate effect on reasoning skills on geometrical shapes and geometry performance. It was also determined that reasoning skills on geometric shapes had a strong effect on geometry performance. The findings of the path analysis conducted on the sub-dimensions revealed that all sub-dimensions had a moderate positive effect on reasoning skills on geometric shapes. It was also found that visual mathematics literacy perception had a moderate positive effect on visual perception, geometry knowledge, spatial intelligence and concretization sub-dimensions and geometry performance.

This protocol describes the preparation of biological samples (specifically from a marine environment e.g. hatchery or RAS unit) for amplicon sequencing. Starting with a biological sample stored in Qiagen buffer ATL, or similar, it begins with a bead beating process to homogenise the sample. Enzymatic lysis using Metapolyzyme and Proteinase K are emplyed to ensure efficient DNA release. The Qiagen DNeasy kit is used to column extract DNA from lysates. Following concentration estimates of DNA elutions, samples are diluted >1:10 to avoid PCR inhibition during amplicon library preparation.
Early Years Math: A Study with Undergraduates in Mathematics based on the Principles of Cultural - Historical Theory
Authors: Giacomelli Camila Porto , Vieira Lopes Anemari Roesler Luersen
Published: September 2020

Background: It is common the idea that the responsibility for learning mathematics worked in the first years of schooling rests solely with the teacher at this stage. This is a mistake since these contents run throughout basic education, and it is important that teachers at other levels understand the mathematics of the early years of elementary school. Objectives: The article aims to discuss the knowledge of mathematics undergraduate students about mathematics in the early years of elementary school. Design: The theoretical and methodological support is based on the assumptions of cultural-historical theory (CHT), which shows that the subject develops and impacts the reality where he/she lives by interactions with others through the acquired knowledge. Setting and participants: The study space consisted of workshops on the operations of addition, subtraction, multiplication, and division, carried out in the project “Knowing the mathematics taught in the early years” and the participants were seven undergraduates from the mathematics degree course. Data collection and analysis: The empirical data were systematised by the organization of the episode "Understanding the teaching of basic mathematics", composed of four scenes. Results: They reveal that when it comes to teaching mathematics in the early years, students show a weakness in relation to basic mathematical knowledge and didactic knowledge to teach them. Conclusions: Although the results come from a specific context, we concluded that it is important for mathematics undergraduates to be able to discuss mathematics teaching in all stages of basic education.

Published: September 2020

Background: Some inconsistencies that appeared when teaching Geometry - using Dynamical Geometry Softwares - to Mathematics undergraduate students, inspired this work . Objectives: To stress the potentialities and, specially, the limitations of Dynamical Geometry Softwares in order of using it correctly by teachers, pre-service teachers and students for learning and teaching situations and investigations in Geometry. Design: Critical analysis study of situations, with examples produced using Dynamical Geometry Softwares, in order to reveal some inconsistencies with respect to the theory. In particular, Geogebra was the software used. Setting and participants: Some of the examples presented here, elaborated in GeoGebra, were briefly discussed in classes of pre-service teachers of mathematics aiming at an awareness of the inconsistencies that may appear using a Dynamical Geometry Software. The authors are the unique participants of the elaboration of those examples. Data collection and analysis: There was not data collection, but only elaboration of examples in order to provide some arguments for future discussions. Results: Examples production shows some limitations of Dynamical Geometry Softwares and that those limitations are insurmountable due to epistemological reasons. Conclusions: Awareness of Dynamical Geometry Software limitations is fundamental for its correct use. Those limitations do not invalidate the software potential. On the contrary, being conscious of both potentialities and limitations of a hardware is a necessary condition to a fruitful use of it.

Background. Highly migrated disc herniations are usually localized in the area of pars interarticularis medially to the vertebral pedicle. Removal of disk herniations of this localization is a difficult technical task.

The study objective is to demonstrate the effectiveness of the transpedicular endoscopic discectomy in the treatment of patients with highly migrated disc herniations.

Materials and methods. The results of treatment of 12 patients with Macnab zone herniations who were in hospital from 2016 to 2018 were analyzed. All patients underwent transpedicular endoscopic sequestrectomy.

Results. Leg pain after surgery regressed in all patients from the initial 7.41 points (visual-analog scale) to 0.67 points by the end of the 1st day, and it was 0.35 points a year later. The average level of back pain by VAS before surgery was 5.25, on the 1st day after surgery – 1.25 points, 1 year after – 0.67 points. Neurological disorders completely regressed in 10 (91.6 %) patients, there were a slight residual L4 dermatome hypesthesia in 2 patients, without disrupting their quality of life. The average Oswestry Disability Index before surgery was 69.17, and 1 year after surgery was 14.12. There were no complications and reoperations.

Conclusion. Transpedicular endoscopic discectomy allowed us to achieve good treatment results in patients with migration of a lumbar hernia by the pedicle. It can be a safe and effective alternative to the transforaminal or interlaminar endoscopic technique.

Authors: Aziz Rasul , Mohammed Aram , Ahmad Faraydwn , Ali Ari
Published: September 2020

The research was conducted at the College of Agricultural Sciences Engineering/University of Sulaimani/ Kurdistan Region-Iraqi to investigate effects of different concentrations of IBA (0, 3000, 4000 and 5000 ppm) and soaking in water for 24 hours on propagation black mulberry (Morus nigra L.) by hardwood cuttings. In this research the parameters of rooting percentage, root number, root length, sprout bud number, shoot length and shoot diameter were measured. Effect of individual factors showed that the highest rooting percentage (15%) was achieved in cuttings soaked in water for 24 hours, as well as improving other traits. Also, the best (23.33%) rooting was found in cuttings dipped in 4000 ppm IBA. Interaction effects of the two factors showed that cuttings treated with 4000 ppm IBA and soaked in water for 24 hours gave the highest (40%) rooting, and the highest other root and shoot traits were achieved in the same interaction as well.
Prediction of Crack Porosity from Other Easily Soil Properties Using Ridge Regression Analysis
Authors: Khurshid Shadan
Published: September 2020

The development of accurate, easy, and low-cost method to determine soil cracks porosity (SCP) is important in the evaluation of ecosystem to manage the hydrological, erosional, and geochemical cycles. Indeed, these procedures are cumbersome, time-and energy-consuming, and costly. Accordingly, intensive efforts are being made to formulate a high-performance model to estimate SCP. Pedotransfer functions (PTFs) have often been developed using multiple linear regression models with no distinction about their involvement in multicollinearity. The paper was focused on ridge regression (RR) to overcome multicollinearity problems via regularizing the regression coefficients by imposing a penalty on their magnitudes. In the application of RR,choosing the ridge parameter (k) is important to control the amount of shrinkage of the regression coefficients. A total of 61 soil samples were analyzed from different land uses (forest, cropland, and pasture) inIraqi Kurdistan Region. Eighty-two percent of the soil sampleswere selected as the training set, and the rest of 11 soil samples (18%) were used as the testing set. Threemethods of modeling regression (simple linear regression SLR, multiple linear regression MLR, and ridge regression RR) were used to formulate accurate PTFs for predicting SCP. The results clearly showed multicollinearity problem (wrong sing and value of regression coefficient) in SMR and the most of MLR; therefore,they are not recommended to be used in predicting SCP. Soil crack porosity was positively correlated with each of clay (C), liquid limit (LL), plastic limit (PL), and percent of shrinkage limit (PLS). While, the most influential variable for predicting SCP is liquid limit (RMSE=126.194 cm2 m-2; adj.R2=0.884). The best model (RMSE=122.786 cm2 m-2, adj. R2=0.891) to predict SCP among all the models is formulated by RR technique when k=0.31395 which gave the lowest intercept value with very low VIF (0.582).

Authors: Mohammed Saman , Al-Jaff Bahrouz
Published: September 2020

Dermatophytosis is a common skin infection especially in closed area with high temperature and humidity. Prisons are considered as closed areas especially for long times existed inmates in addition to some risk factors that may increase dermatophytosis. To investigate the prevalence and the risk factors of dermatophytosis in Suse federal prison for men at Sulaimani, northern Iraq, a total of 1620 inmates were clinically screened. Clinically suspected dermatophytosis by specialists were 139 (8.5%), they distributed on 102 (73%) Tinea pedis, 18 (12%) Tinea cruris, 14 (10%) Tinea corporis, 4 (3%) Onychomycosis, and 1 (0.7%) tinea mannum. By microscopical, cultural and PCR-RFLP typing procedures 50 cases were confirmed that distributed on 25 (50%) tinea pedis, 15 (30%) tinea cruris, 9 (18%) tinea corporis and 1 (2%) onychomycosis. The causative agents were Trichophyton rubrum 16 (32%), Trichophyton mentagrophytes and Trichophyton interdigitale 14 (28%) for each, Epidermophyton floccosum 4 (8%) and Trichophyton schoenleinii 2 (4%). Trichophyton interdigitale was the most frequently isolated from tinea pedis (40%), Trichophyton rubrum and Trichophyton mentagrophytes from tinea corporis (33% for each) and Trichophyton rubrum from onychomycosis and tinea cruris (%100 and 40% respectively).  Antifungal administration and frequency of bathing were with significant effect on identification of the causative agent by direct KOH test (P= 0.000 and P= 0.026 respectively) and on its recovery by culture method (P= 0.000 and P= 0.016 respectively). The non-significant risk factors were age (P= 0.07), education level (P= 0.82), smoking (P= 0.61), and duration of imprison (P= 0.557). KOH exam was fast and cheap but it is less specific and sensitive. Culture method of identification is essential to identify species of dermatophytes, but it was time consuming and with problems related with confusion in dissemination between species morphologically that could be avoided by PCR-RFLP method which we consider it as a golden method for identification in spite of its high cost but it is with less time, correct identification, and highest sensitivity.

Both F. hepatica and F. gigantica are considered as the main causes of human and animal fascioliasis that have much medical and economic importance worldwide. Nowadays, identification and description of Fasciola species using molecular-based techniques are critical and reliable approach in most laboratories and research centers. Thus, this research aimed to investigate the prevalence of fascioliasis and molecular characterization of isolated Fasciola species in sheep and goats in Sulaimaniyah province, Northern Iraq. Briefly, a total of 100 liver samples from slaughterhouse and 100 fecal samples from the animal field were collected from sheep and goats. In overall collected liver specimens, only 30 (15%) samples were found to be positive using polymerase chain reaction (PCR) assay, from which only 6 samples were selected for sequencing of the partial mitochondrial 28S rRNA gene and codon analysis. Simultaneously, the collected fecal samples were also analyzed using the Fecal Egg Count Reduction Test (FECRT), in which only 4 samples were positive. The results revealed that the identified four field sequences strains were F. hepatica and the other two field sequences were F. gigantica. In conclusion, we revealed that both F. hepatica and F. gigantica were distributed in Sulaimaniyah province and the mitochondrial 28S rRNA gene is confirmed as a potential biomarker in identifying various Fasciola species.

Reservoir rock properties of the tight carbonate of Upper Cretaceous Shiranish Formation was studied in three selected wells in Taq Taq Oilfield/ Iraqi Kurdistan Region. The penetrated thickness of the formation by the studied wells of TT-04, TT-20, and TT-21 were 249, 290.8, and 236m respectively. The available logs and core test data were mainly dependant in characterizing the formation. The dominant limestone lithology of the formation was identified using Neutron-Density and M-N crossplots. The shale content, as calculated from the Gamma ray log, appeared to be highest in the lower part of the formation with about 15-30%. The shale content of Shiranish Formation are mainly consists of Glauconite, Illite, and Micas with a little contribution from other kinds of clay minerals like Montmorillonite. The total porosity of Shiranish Formation is generally less than 10% whereas the lower part of the formation has the lowest porosity (less than 5%). The calculated permeability through Multiple Regression Analysis method and by using the available core test data showed that The formation is generally of less than 10mD permeability. The lower part of the formation (at the two wells of TT-20 and TT-21) has relatively higher permeability compared to the middle and upper part of the formation. Three distinctive reservoir units were identified in this study in Shiranish Formation depending on variations in the shale content, porosity, and permeability. Reservoir unit (RU-1) at the upper part of the formation in the well TT-21is considered to be of the best reservoir property among the identified reservoir units in the three studied wells. The expected contribution of minor and large fractures in enhancing the permeability of the formation approved through output of the existed Formation Micro Image log for the lower part of the formation in the well TT-21.

Continuation of pregnancy may sometimes be life threatening for the mother and the fetus if the indication is frequently prolonged. Sometimes, it is necessary to bring on labor artificially because of safety concerns for the mother and her baby. A descriptive observational study performed in 200 postdate pregnant women who attended to the delivery room for induction of labor. The Purposive data collection took 3 consecutive months starting from February 28th,  2019 until May 26th 2019. A questionnaire and a checklist were designed for the purpose of the study and Bishop score, APGAR and patient’s chart were used. Content and Face Validity of the instrument was established and the reliability was measured by using Cronbach’s alpha = 0.96. Formula for research, instrument. Descriptive & inferential statistical used for analysis  data  it was done with the SPSS version 22.0 software. Women’s education, body mass index and method of delivery with mode of delivery had significant association. The overall caesarean section rate in this study was quartered. Half of them had a variety of complications and 44% of newborn needed admission to the neonatal intensive care unit. The rate of cesarean section was higher among participant were induced with misoprostol than who were induced by oxytocin. The statistically no significant relationship between the birth outcome with socio-demographic factors (age, residency, occupation and educational level), gravidity and Bishop score and the mode of delivering was determined in the study.

A systematic analysis of vascular paroxysm pathophysiology in perimenopause: methods for nutritional correction
Authors: Gromova O. A. , Torshin I. Yu. , Limanova O. A. , Tapilskaya N. I.
Published: September 2020

Materials and Methods. A systematic analysis of publications retrieved from PubMed/MEDLINE database as well as in the list of primary sources of the identified scientific papers was carried out by using current methods for large data analysis within the framework of topological and metric approaches applied for data recognition/classification. A map of molecular-pathophysiological processes was compiled followed by performing analysis of metric condensations.

Results. Three clusters of terms describing an impact of various biological processes into the pathophysiology of hot flushes were identified: inflammation combined with insulin resistance (cluster 1), the presence of chronic comorbid pathologies in patients (cluster 2), and disorders of serotonin metabolism (cluster 3). The use of menopausal hormone therapy (MHT) is not accepted for all patients. A promising direction in treatment of mild and moderate hot flushes is based on using nutraceuticals: vitamins, trace elements and substances obtained from plant extracts (isoflavones, phytoestrogens, etc.). Here, this set of interactions between pathophysiology of hot flushes and deficiency of certain micronutrients, inflammation, insulin resistance, chronic comorbid pathologies and disorders of serotonin metabolism is described. Replenished deficiency of vitamins C, E, A, B2, PP, B6, B12, and folates aids to reduce chronic inflammation, insulin resistance and normalize functioning of the autonomic nervous system. Natural and synthetic agonists of GABA receptors and tryptophan derivatives are necessary for serotonin biosynthesis and elimination of other neurotransmitter imbalances in order to normalize activity of the hypothalamic thermoregulatory region.

Conclusion. Plant isoflavones (including phytoestrogens) together with vitamins and other micronutrients help to overcome estrogen-dependent withdrawal symptoms and eliminate dysfunction of autonomic nervous system
Electronic characteristics of asymmetric triple GaAlAs/GaAs and GaInAs/GaAs quantum wells depending on Al and In concentration

Published: September 2020

Herein, the electronic characteristics of asymmetric triple Ga1-x Alx As/GaAs quantum wells (A model) and Ga1-x Inx As/GaAs quantum wells (B model) have been examined as dependent on Al and In concentration. The energy levels, the wave functions and the finding probability of electron in quantum well (QW) of these systems under effective mass approach were concluded by Schrödinger equation solution. According to our results, the main differences between models A and B are effective mass and energy gap. For A model, GaAlAs is the barrier and GaAs is the well. Whereas for B model, GaAs is the barrier and GaInAs is the well. Also, the energy levels and the potential height of B model are unceasingly higher than of B model. The concentration ratio has a great impact on the electronic features of the asymmetric triple quantum well (ATQW). These features have a convenient attention for the purpose of adjustable semiconductor devices.

This review summarizes the core principles of immediate and early rehabilitation with aerobic exercises of various intensity in patients following cardiac surgery.

One of the main principles of cardiac rehabilitation is early mobilization of patients after cardiac surgery with the subsequent expansion of physical activity modes. The optimal time for commencing early rehabilitation and its intensity in patients who have undergone cardiac surgery remain controversial. In addition, cardiac rehabilitation programs for elderly patients and those with severe with comorbidities have not been studied yet. This review presents the results of the recent meta-analyzes and studies, focusing on the efficacy and safety of immediate and early aerobic exercise as a core component of rehabilitation in different cohorts of patients, who have undergone cardiac surgery.
ELECTRONIC LEGITIMATION AND INTERACTION OF ENTREPRENEURSHIPS WITH REGISTRATION (TAX) AUTHORITY
Authors: Trofimova E. V.
Published: September 2020

The article studies legal aspects of transformation entrepreneurships and registration authorities (tax authorities) to mostly electronic form. Digital transformation of state legal services improves quality, reducing cost of provision and enhances accessibility thereof for business and individuals. Digitalization of control activity of authorities lets not only to raise key performance indicators but, as well, to develop new control approaches to shift them to prevention rather than repression way. Digitalization of the control area together with positive consequences can bring implications of unauthorized access to entrepreneurial data in electronic registries with intent to disclosure or corruption thereof. Solution to address the implications requires taking complex measures including legal, organizational, human resource development and technical activities.
