ВПЛИВ НАВАНТАЖЕННЯ РОЗПОДІЛЬНОЇ МЕРЕЖІ НА ПІДВИЩЕННЯ НАПРУГИ В ТОЧЦІ ІНВЕРТОРНОГО ПІДКЛЮЧЕННЯ ФЕС
Authors: Gaevskii О. , Gaevskaya A. , Konovalov M. 
Published: September 2022

Розглянуті причини підвищення напруги на виході фотоелектричної станції (ФЕС) у складі розподільної мережі, пов’язані з раптовими змінами взаємного рівня споживання в мережі й генерації станції. Вихід значення напруги змінного струму в спільної точці інверторного підключення (СТІП) за гранично допустимі значення є дуже важливим фактором, оскільки він призводить до автоматичного відключення інверторів ФЭС від розподільної мережі й перериванню постачання енергії в мережу. Для аналізу цього фактора була застосована еквівалентна схема з подвійним живленням на кінцях радіальної розподільної лінії: від підстанції й ФЕС. Схема зі зворотним потоком потужності включала такі послідовні компоненти: інвертор – з’єднувальний відрізок кабелю – підвищувальний трансформатор – розподільна лінія з еквівалентним навантаженням – трансформаторна підстанція – високовольтна мережа. Потік потужності навантаження був локалізований в певному вузлі розподільної лінії, й тому еквівалентна схема була зведена до тривузлової схеми заміщення: ФЕС – вузол споживання – ПС. В процесі моделювання були проаналізовані різні співвідношення рівнів споживання в мережі й генерації ФЕС, а також різні місця локалізації навантаження вздовж лінії. Як показують проведені розрахунки енергосистеми із подвійним живленням та змінним споживанням, вплив рівня споживання при фіксованій генерації суттєво впливає на зростання або зменшення напруги в СТІП до мережі. Раптове падіння потужності навантаження при незмінному рівні генерації ФЕС та незмінних уставках системи РПН підстанції призводить до зростання вихідної напруги інвертора – тим більшою мірою, чим більше загальний імпеданс мережевого обладнання (розподільної лінії й підвищувального трансформатора) та з’єднувального кабелю між інвертором і підвищувальним трансформатором.

Published: September 2022

Background: Although conception is discouraged in women with Eisenmenger syndrome, in inevitable circumstances, careful and meticulous planning of anesthesia can help the parturient survive the ordeal of a cesarean section. Anaesthetic management is aimed at avoiding haemodynamic changes that increase right-to-left shunt, thereby worsening hypoxemia. This study aimed to present a case of a pregnant woman with Eisenmenger syndrome who underwent caesarean section under general anesthesia management with severe preeclampsia.
Case presentation: A 42-year-old pregnant woman (gravida 3, para 1, abortion 1) was admitted to our hospital at 38 weeks gestation with the chief complaint of shortness of breath and severe preeclampsia. Physical examination revealed cyanotic with clubbing fingers and elevated jugular venous pressure. Laboratory investigations did not reveal any abnormalities. Electrocardiography (ECG) shows normal sinus rhythm and right atrial deviation. General anesthesia was chosen due to obstetric complications, namely severe preeclampsia. The patient was premedicated with a gastroprotective agent, ranitidine 150 mg. At follow-up anesthesia 36 hours after surgery, the patient scored for maximum perioperative comfort and satisfaction.
Conclusion: A multidisciplinary approach is needed to secure maternal and fetal survival for patients with Eisenmenger syndrome. Termination of Caesarean section under general anaesthesia may be the method of delivery that can be used, but care must be taken to avoid excessive and rapid blockade, dehydration, and hypoxaemia.

Ante el confinamiento provocado por la pandemia de COVID-19, algunos docentes comenzaron a utilizar instrumentos de la educación a distancia. Esto incluyó exámenes computarizados, realizados en línea mediante plataformas digitales, calificados de forma automatizada, con el consiguiente cuestionamiento de si la evaluación computarizada podría seguir siendo usada cuando se regrese a las clases presenciales.
Con el fin de comparar los exámenes tradicionales con los exámenes computarizados, en esta investigación se utilizaron el enfoque cualitativo, técnicas de recolección de datos del análisis documental, la encuesta y las escalas estimativas. Los exámenes computarizados se usaron durante todo un semestre (septiembre 2020-enero 2021), procediendo a evaluar su uso al finalizar el mismo.
Al final, se encontró que los exámenes tradicionales son superiores a las evaluaciones en línea. Sin embargo, los exámenes computarizados tienen ventajas que conviene aprovechar, por lo que son una opción interesante como evaluación complementaria en los cursos de inglés.

Приведены результаты численных и экспериментальных исследований концентраций основных компонентов продуктов пиролиза горючего строительного и отделочного материала (на примере древесины). Установлены значения времени задержки срабатывания пожарных извещателей перспективных типов. Показано, что обнаружение газообразных продуктов пиролиза с использованием газоанализатора и пожарных извещателей пламени происходит за существенно меньшее время по сравнению со временем их обнаружения тепловыми и дымовыми извещателями. На основе результатов анализа концентраций газов в непосредственной близости от изучаемых материалов выделены необходимые и достаточные технические решения по раннему обнаружению возгораний.
The work of fire extinguishing systems or fire brigades usually occurs when damage to health, equipment and personnel has already occurred. Therefore, it is especially urgent to create systems for early detection of fires in buildings according to the gas concentrations. This approach creates objective prerequisites for registering signs of incipient stages of fires. This paper presents the results of theoretical and experimental studies of the concentrations of the pyrolysis products of a potentially combustible building and finishing material (wood). Also, the response times of various types of fire detectors (thermal fire detector, wired and wireless smoke detector, flame fire detector, gas analyzer) were experimentally determined for further comparison of their response inertia. The authors use the box isolated from the external environment (with dimensions of 1,5 x 1 x 1,25 m) for experimental studies. Box includes ventilation system, recording devices (gas analysis system, heat and smoke fire detectors, flame fire detectors), as well as a personal computer for collecting and recording information. The concentration ranges of the pyrolysis products were analyzed using a Test-1 gas analyzer. The mathematical model of thermal decomposition of a solid material permitting to analyze the concentrations of the main products of pyrolysis of a combustible material was developed using a complex COMSOL Multiphysics. The results of experimental research and mathematical modeling are in satisfactory agreement. It is shown that the recording of pyrolysis products of combustible materials occurs in a shorter time (compared to the recording of other signs of fire (smoke formation, rise of temperature). The developed mathematical model can be used to determine the ranges of concentrations of gaseous products of wood pyrolysis.

Abstract
We report that object 282P/(323137) 2003 BM80 is undergoing a sustained activity outburst, lasting over 15 months thus far. These findings stem in part from our NASA Partner Citizen Science project Active Asteroids (http://activeasteroids.net), which we introduce here. We acquired new observations of 282P via our observing campaign (Vatican Advanced Technology Telescope (VATT), Lowell Discovery Telescope (LDT), and the Gemini South telescope), confirming 282P was active on UT 2022 June 7, some 15 months after 2021 March images showed activity in the 2021–2022 epoch. We classify 282P as a member of the quasi-Hilda objects (QHOs), a group of dynamically unstable objects found in an orbital region similar to, but distinct in their dynamical characteristics to, the Hilda asteroids (objects in 3:2 resonance with Jupiter). Our dynamical simulations show 282P has undergone at least five close encounters with Jupiter and one with Saturn over the last 180 yr. 282P was most likely a Centaur or Jupiter-family comet (JFC) 250 yr ago. In 350 yr, following some 15 strong Jovian interactions, 282P will most likely migrate to become a JFC or, less likely, an outer main-belt asteroid orbit. These migrations highlight a dynamical pathway connecting Centaurs and JFCs with quasi-Hildas and, potentially, active asteroids. Synthesizing these results with our thermodynamical modeling and new activity observations, we find volatile sublimation is the primary activity mechanism. Observations of a quiescent 282P, which we anticipate will be possible in 2023, will help confirm our hypothesis by measuring a rotation period and ascertaining the spectral type.

Published: September 2022

Abstract
We estimate the volume of material that could be excavated from asteroid Dimorphos and expelled into the surrounding space by the DART impact on 2022 September 26. What emerges from our computations is that the total volume of ejected material could be as high as 5710 m3. Assuming that the fraction of fine-dust particles constitutes 5% of this volume, we estimate the apparent brightness of the ejecta to be (6.5 ± 1.5) mag in the V filter. This makes ground-based astronomical observations of the DART impact on asteroid Dimorphos with small telescopes feasible.

Published: September 2022

Abstract
Using a 3D general circulation model, we demonstrate that a confirmed rocky exoplanet and a primary observational target, TRAPPIST-1e presents an interesting case of climate bistability. We find that the atmospheric circulation on TRAPPIST-1e can exist in two distinct regimes for a 1 bar nitrogen-dominated atmosphere. One is characterized by a single strong equatorial prograde jet and a large day–night temperature difference; the other is characterized by a pair of mid-latitude prograde jets and a relatively small day–night contrast. The circulation regime appears to be highly sensitive to the model setup, including initial and surface boundary conditions, as well as physical parameterizations of convection and cloud radiative effects. We focus on the emergence of the atmospheric circulation during the early stages of simulations and show that the regime bistability is associated with a delicate balance between the zonally asymmetric heating, mean overturning circulation, and mid-latitude baroclinic instability. The relative strength of these processes places the GCM simulations on different branches of the evolution of atmospheric dynamics. The resulting steady states of the two regimes have consistent differences in the amount of water content and clouds, affecting the water absorption bands as well as the continuum level in the transmission spectrum, although they are too small to be detected with current technology. Nevertheless, this regime bistability affects the surface temperature, especially on the night side of the planet, and presents an interesting case for understanding atmospheric dynamics and highlights uncertainty in 3D GCM results, motivating more multimodel studies.

Hura crepitans seed oil (HCSO) remains under-utilized, largely due to the scarcity in data regarding its biochemical properties. To investigate the functional and pro-inflammatory responses to HCSO, twenty-four male rats were grouped into four and received compounded diets containing 5%-HCSO; 10%-HCSO; 15%-HCSO; and 15%-AHO (as control) for eight weeks. The functional responses and the expression of pro-inflammatory cytokines and their receptors were appraised. The organ function biomarkers in rats fed with HCSO-supplemented diets were statistically similar to those of control rats, except for uric acid and creatine levels, which were significantly lower in the HCSO-fed groups, and the urea level, which was elevated in all HCSO-fed groups. Also, HCSO significantly downregulated the expression of pro-inflammatory cytokines (TNF-α, IL-1α, IL-1β, and IL-6) and their receptors (IL-1R and IL-6R), when compared to the control group. Our results highlight the reno- and cardio-protective potentials of HCSO, as well as its anti-inflammatory potentials.

Le problème qui reste est : comment garantir que cette expérience reste enregistrée dans les discours du temps post-pandémie et continue d’être audible pour, de cette manière, éviter le retour de la fiction de normalité et d’inaltérabilité qui nous capturait ? Comment retenir l’expérience d’un désir qui, du moins pendant cet intervalle, s’est acheminé librement vers d’autres formes de satisfaction et de réalisation ? Il y aura des forces habiles, très bien instruites, étudiant le sujet pour clôturer cette mémoire, la bannir, l’interdire, pour de cette manière garantir la continuité d’une « normalité » que la pandémie avait interrompue. Comment nous préparer pour que l’oubli ne survienne pas ? Mais aussi, comment éviter que la perte de l’expérience accumulée en 2001 ne se produise à nouveau ?.

Published: September 2022

The study aims to explore the roles of indigenous Garo women in transforming their families in Bangladesh. A quantitative approach was applied to conduct the study while the social survey method was used to collect data and information. The study reveals that the socio-economic status of Garo women is very poor as 35% of them completed the primary level of education and 40% passed the secondary level of education while 64% of Garo women are day laborers and 61% are loan receivers. Conventional role-female headship has been changing overwhelmingly as both husband and wife are playing vibrant roles in the family building where 80% of family decisions are being taken jointly. Though the traditional role of female headship is being changed, women have to perform 69% of household activities. Their participation in local social organizations is impressive (74%) but they are reluctant to involve in local politics.

Published: September 2022

Thisstudy aimed to assess the pathogenicity and vaccine efficacy of fowl adenovirus serotypes 4 and 11, causing inclusion body hepatitis hydropericardium syndrome in broilers. The study was carried out on 144-day-old Cobb broiler chicks divided into six experimental groups, each of 24 birds. Group, I birds served as a control without any vaccine or viral challenge, while birds of Group II were vaccinated with commercial vaccine on 6th day. Group III and IV birds were non-vaccinated and challenged with 107 TCID50 of FAdV serotype 4 and 11, respectively, on the 27th day. In contrast, Group V and VI birds were vaccinated on the 6th day and challenged with 107 TCID50 of FAdV serotype 4 and 11 on the 27th day. The challenge of FAdV serotype 4 led to 66.66% mortality, and serotype 11 produced 5.00% mortality in the experimental groups. The challenge of the virus led to the production of clinical signs such as depression, huddling, reduced feed intake, reluctance to move, and terminal gasping before death. Characteristic gross lesions of IBH-HPS were observed in birds that died after the challenge of serotypes 4 and 11 of FAdV. The liver was enlarged with focal areas of necrosis, subcapsular hemorrhages, and mild fatty changes. The heart was flabby, congested, and showed hydropericardium with an accumulation of clear watery to a yellow jelly-like fluid in the pericardial sac. The kidneys were enlarged and hemorrhagic. On microscopic examination, the liver showed multifocal areas of necrosis with infiltration of mononuclear cells, mild fatty changes and large basophilic intranuclear inclusion bodies. The birds that died after the challenge of the virus were positive for the presence of FAdV upon PCR. The vaccine efficacy study indicated that the vaccine provided satisfactory protection against Fowl Adenovirus challenge in experimental groups V and VI.
