FEATURES OF THE SPATIAL-ENERGY PROFILE FORMATION FOR THE VISIBILITY ZONE OF ACTIVE-PULSE VISION SYSTEMS ON INCLINED PATHS
Authors: Kuntsevich B. F. , Shabrov D. V. 
Published: May 2022

We numerically investigated the features of the formation of the space-energy profile of the visibility zone by active-pulse vision systems (APVS) on inclined paths with the diffuse reflection of vertically and horizontally oriented objects. We proposed to take into account the presence of a noise threshold in APVS and
introduced the concept of signal contrast that permited to bring the results of the numerical modeling of the potential capabilities of APVS closer to those realized experimentally. It is shown that the position used earlier, when the length of the visibility zone was uniquely determined by the sum of the duration of the illumination and strobing pulses, is valid if the signal contrast is close to unity. With the considered typical parameters, the maximum observation range of vertical objects is approximately 3.8 times higher than the similar value for horizontal objects. When the APVS installation height increases, the signal value for vertical objects decreases monotonically, and for horizontal objects this dependence has a maximum. For the first time, a decrease in the length of the visibility zone for fixed durations of illumination and strobing pulses with an increasing delay distance is experimentally confirmed.

Cauchy Problem Solvability with the Data Specified on the Rectangle Boundary for a One-Dimensional Parabolic Equation
Authors: Пятков С. Г. 
Published: May 2022

Рассматривается одномерное параболическое уравнение в прямоугольнике (0,T)× (a,b), на одной из боковых сторон которого заданы данные Коши, а также задано условие Коши в начальный момент времени. Решение этой задачи ищется в пространстве Соболева. Построен класс данных, для которого решение задачи Коши с данными Коши на боковой поверхности прямоугольника существует и единственно. Класс является минимальным, т. е. условия гладкости на данные нельзя ослабить, они необходимы и достаточны для существования решений в данном классе Соболева. Решение является регулярным, это означает, что все производные, входящие в уравнение, принадлежат пространству L2. Задача сама по себе некорректна по Адамару. Математические модели такого типа возникают при описании процессов тепломассопереноса. Имеется большое количество работ, посвященных задачам такого типа, как в одномерном, так и в многомерном случае. В литературе основное внимание уделено численному решению задачи, поскольку она возникает во многих приложениях. Кроме того, известны теоремы единственности решений, оценки устойчивости решений и теоремы существования решений в классах Хольгрена. Мы немного уточняем последние результаты и получаем теорему существования решений в классах конечной гладкости.
We consider a one-dimensional parabolic equation in the (0,T) × (a,b) rectangle. The Cauchy data are specified on one of its lateral sides. The Cauchy condition is also specified at the initial moment. The solution to this problem is sought in the Sobolev space. A data class was constructed for which there is a unique solution to the Cauchy problem with the Cauchy data specified on the lateral side of the rectangle. The class is minimal, i. e., the smoothness conditions applied to the data cannot be weakened. They are necessary and sufficient for the existence of solutions in a given Sobolev class. The solution is regular which means that all derivatives in the equation belong to L2 space. The problem is ill-posed in the Hadamard sense. Mathematical models of this type arise when describing heat and mass transfer. There are many papers on such problems for both one-dimensional and multidimensional cases. The available sources mostly focus on numerical solutions, since the problem is found in many applications. Besides, there are uniqueness theorems and stability estimates, and existence theorems for solutions in Holmgren’s classes. We slightly refined the recent results and obtained an existence theorem for solutions in finite smoothness classes.&nbsp;

Пандемия коронавируса нанесла ущерб системе здравоохранения с момента ее вспышки в 2020 году и привела к более чем 6 миллионам смертей во всем мире, а в Казахстане более 13 тысяч. Клинические проявления COVID19 варьируются от бессимптомного носительства до тяжелой пневмонии и опасного для жизни острого респираторного дистресссиндрома (ОРДС). Первые усилия пандемии были направлены на лечение легочного компонента COVID19, однако имеются достоверные данные о сердечных осложнениях, связанных с вирусом. Предполагается, что это вызвано выраженной воспалительной реакцией, а также прямым вирусным повреждением. Аритмии, острое повреждение миокарда, миокардит, кардиомиопатия, тромбоз и фиброз миокарда вот некоторые из наблюдаемых сердечных осложнений. Отмечаются высокие показатели заболеваемости и смертности среди лиц, страдающих сердечными заболеваниями, связанными с COVID-19

The clinical manifestations of COVID19 range from asymptomatic carrier to severe pneumonia and lifethreatening acute respiratory distress syndrome (ARDS). The rst efforts of the pandemic were aimed at treating the pulmonary component of COVID19, but there is reliable data on cardiac complications associated with the virus. It is assumed that this is caused by a pronounced in ammatory reaction, as well as direct viral damage. Arrhythmias, acute myocardial injury, myocarditis, cardiomyopathy, thrombosis and myocardial brosis are some of the observed cardiac complications. There are high rates of morbidity and mortality among people sufering from heart diseases associated with COVID-19

Published: May 2022

Las aves guaneras (guanay, piquero peruano y pelícano peruano) son endémicas del ecosistema norte de la Corriente de Humboldt, debido a que solo en ella encuentran su principal presa. La distribución de las especies esta mediada por diversos factores como variabilidad medioambiental, características biológicas de cada especie y disponibilidad desus presas. Este trabajo tuvo como objetivo comparar la presencia de estas aves en el litoral peruano durante los cruceros de evaluación de recursos pelágicos llevados a cabo en primavera los años 2018 y 2019. Durante el 2018 el guanay y el piquero tuvieron mayores concentraciones en la zona correspondiente al stock norte de anchoveta (Engraulis ringens), mientras que el pelícano en los extremos norte y sur del Perú. En el 2019 el guanay y el piquero nuevamente se encontraron en mayor concentración en la zona del stock norte deanchoveta, pero presentaron distancias a costa significativamente mayores que en el 2018. Esto podría estar relacionado con la mayor expansión de las aguas costeras frías (ACF). La distribución de las aves guaneras está ligada a la distribución espacial de las ACF porque en ellas se encuentra su principal presa, la anchoveta.La distribución de los depredadores superiores puede reflejar lo que pasa en un ecosistema debido a su papel integrador.

This study aimed at the possibility of using X-rays in the control of fungi. Treatments of healthy and infected seeds of peas with microwave radiation resulted in a decrease in the frequency of fungi in the tested seeds, and increasing the time of treatment leads to a significant reduction in its number with a complete elimination of Alternarai iso1 fungi isolated from the seeds when exposed to microwave radiations for 120 seconds. The radiations did not have any impact on Fusarium sp iso3. However, Exposing infected seeds to this radiation for 60 seconds was enough to eliminate Rhizoctoinia and Sclerotinia, and for 90 seconds to eliminate Botrytis sp fungi for all tested seeds. On the other hand, microwave radiations had an effect on germination ratio of pea seeds, This effect increases by increasing the treatment time. The decrease of this effect was high at exposure times ranging from 120-180 seconds.

Metabolic syndrome (Met S) is known as the clustering of several metabolic abnormalities; it can be diagnosed according to several different criteria such as the International Diabetes Federation (IDF) criteria, which is intended for global application in clinical practice. Hematological tests (total Leukocyte count, differential count, platelet count and ESR) has been considered to be a marker of inflammation, several studies have examined the relationship between hematological tests, and components of metabolic syndrome; the data reveals correlations between it and metabolic syndrome in some cross-sectional studies. The study used participants recruited from Albaida and Almarj cities outpatient clinic. History of hypertension, diabetes, Blood pressure, were taken, height, weight, and waist circumference were measured body mass index (BMI, kg/m²) was calculated. Blood samples were collected for hematological tests and others. The study subject was included and categorized according to IDF criteria. A total of 192 residents aged 16 to 85 years were investigated, 80 (41.7%) participants were Males and 112 (58.3 %) were Females. The mean BMI was 29 (St. Dev±07). Rates of underweight, normal weight, overweight and obesity were 4.7%, 24.5%, 27% and 43.75%, respectively.Prevalence of Metabolic Syndrome in our study according to IDF Criteria is 25.5 % ( males 12.5% and females 13%), central obesity, high plasma glucose, high blood pressure, elevated TG accounted for development of Met S.Inflammatory markers showed no significant difference between Met S and None-MetS groups, which could be explained by high prevalence of overweigh and obesity in none-MetSsyndrome persons in our study group

Diurnal and Seasonal variations of Heat-flow Into soil at Waltair
Authors: PADMANABHAMURTY B. P. , SUBRAHMANYAM V. P. 
Published: May 2022

Heat-flow into the soil is evaluated indirectly from temperature profiles and measured directly transducer on representative days in different months. On calm and clear days, the heat conveyed in either direction (on a daily basis) is roughly of the same magnitude, but during transition months or when there are raped upward or downward trends of temperature variation, some positive or negative carry-over to the next day is observed. Significant features of the seasonal curves are the post-monsoon peak in the downward fluxes and early summer peak in the outward fluxes. The early evening minimum in the diurnal curves has the lowest magnitude in July and has another lower value between December and January and its highest value in March. The time of occurrence in course of day of this minimum is earlier in winter than in summer with a swing-back to its winter value immediately after the withdrawal of the southwest monsoon.

Radar observations on the formation of cumulus clouds near Calcutta during the monsoon season of 1958 have been presented. RHI data on 83 individual cloud cells have been analysed and their rates of growth and decay calculated. It has been suggested that the condensation-coalescence process is responsible for the initiation of precipitation in convective clouds during monsoon season near Calcutta.
Some characteristics of the Southwest Monsoon Circulation
Authors: RAO Y. P. 
Published: May 2022

The southwest monsoon is probably the largest local perturbation on the general circulation of the atmosphere, Meridional transport of mass, heat energy and angular momentum associated with the southwest monsoon circulation have been computed from the upper air data of Singapore, Nairobi, Madras, Bombay, Nagpur and New Delhi for July and August 1955. In view of the large airflow in lower levels across the equator in this period, mass exchange between the hemispheres is important. At Singapore and Nairobi, both near the equator, compensating southward flow exists at 200-and 600-mb levels respectively. There is still significant net flow northwards at Singapore and southwards at Nairobi, probably representative of the eastern and western sections of the monsoon circulation. In the southwest monsoon area due to the large cloudiness, the solar energy absorbed by the ground and the lower atmosphere decreases appreciably and is in a portion slightly less than the outgoing radiation. There is advective flux of heat from the north into this ‘sink’. Necessity and evidence for transport of heat from summer to winter hemisphere is discussed. Angular momentum flows into the monsoon area from the north and more so northwards across the equator at Singapore.

Ontslagvergoeding na beëindiging internationaal arbeidsverleden: een fiscale update
Sinds 5 februari 2022 wordt het heffingsrecht over ontslagvergoedingen in internationale situaties niet langer bepaald op basis van het werkpatroon in de laatste twaalf maanden van de dienstbetrekking, maar (in beginsel) op basis van het werkpatroon gedurende de gehele diensttijd waarop de ontslagvergoeding is gebaseerd. Deze verandering in aanpak zou geschikt(er) zijn om dubbele (non) heffing te voorkomen. In dit artikel gaan de auteurs nader in op het nieuw aangekondigde beleid rondom ontslagvergoedingen. Voor werkgevers is het van belang om op de hoogte te zijn van deze ontwikkeling omdat het een impact kan hebben op de inhouding van loonbelasting over ontslagvergoedingen van cross-border employees.
Conductivity increased in Upper Ohio River Valley streams during the hot and dry summer of 2020
Authors: Huff Emily , Wood James 
Published: May 2022

As the climate begins to change, streams are faced with rising water temperatures and prolonged droughts. Droughts can lead to low flow and increases conductivity concentrations in streams, which can cause stressful events for organisms present. We collected water chemistry data at 24 sites over the summer months of 2019 and 2020 to see if there were any significant differences between the years. We sampled streams ranging in size from headwater to 8th order and impairment ranging from biologically healthy to acid mine drainage (AMD) impacted. We found conductivity to be higher at all of our sites in 2020, while 14 of the 24 had warmer water temperatures. In our non-AMD sites, conductivity increased by 100 µS cm-1 in 2020 posing increased stress for organisms present, while sites affected by AMD were always over 1,000 µS cm-1. Rising temperature and increasing conductivity create challenges for sensitive species while more tolerant species become more dominant.

Published: May 2022

Background
Urothelial carcinoma is the most common malignancy in the bladder with an incidence up to 95% and 70-85% of them are bladder infiltrating urothelial carcinoma. To improve the management of bladder urothelial carcinoma, prognostic factors are required. One such factor is angiogenesis, which affects growth, development and metastasis. Vascular endothelial growth factor (VEGF) is the main pro-angiogenic factor to control angiogenesis. Expression of VEGF is correlated with progression of bladder infiltrating urothelial carcinoma, such as grade and lymphovascular invasion. The aim of this study was to determine the correlation of VEGF expression with grade of differentiation and lymphovascular invasion in bladder infiltrating urothelial carcinoma.
Methods
This research was a retrospective observational cross sectional study with 48 cases of bladder infiltrating urothelial carcinoma in four Anatomical Pathology Laboratory in West Sumatera 2018 and 2019. Samples were reevaluated of HE slide for grade of differentiation and lymphovascular invasion. VEGF expressions in tumor cell s were analyzed using immunohistochemistry staining. Bivariate statistical analysis used Fisher's Exact test and value p<0.05 was considered significant.
Results
Bladder infiltrating urothelial carcinoma high grade had more positive VEGF expression (91.7%), while low grade had more negative VEGF expression (58.3%). Lymphovascular invasion positive was mostly found with positive VEGF expression (75%). Statistical analysis showed significant correlation between VEGF expression with grade of differentiation (p=0.001) and lymphovascular invasion (p=0.004).
Conclusion
The conclusion was VEGF expression had significant correlation with grade of differentiation and lymphovascular invasion of bladder infiltrating urothelial carcinoma.
