BOOSTING CATEGORISATION SYSTEM IN THE UK TRICS DATABASE AND DEVELOPING NEW TRIP PRODUCTION MODELS
Authors: A. Asad Firas H.
Published: June 2023

In the UK, TRICS is a national trip generation databases and system. It is recommended to be used in quantifying traffic impacts of new residential developments. Thus, any enhancement in its methodology will positively influence the transport assessment process. This paper has three objectives; first, to examine the possibility of proposing new statistically-proven grouping for the TRICS residential land use subcategories. The second objective is to use the proposed grouping to construct parsimonious models for home-based trip production that can aid in quantifying traffic impact assessment. The third objective is to examine the validity of the developed models against two of the most internationally recognised trip information systems; the UK TRICS and the US ITE Trip Generation Manual. The statistical analysis ended up with new more accurate grouping where based on it eight trip production model were built. The developed models were found to be practical and rigorous.
THE FRICTION RESISTANCE EFFECT ON THE HYDRAULIC JUMP LOCATION AND ENERGY DISSIPATION, A LABORATORY STUDY
Authors: Jafar Muthanna Sadiq
Published: June 2023

The location of the jump downstream the hydraulic structures outlets is an important parameter taken into considerations within the construction of the downstream protection works. One of the ways of moving the jump into a closer distance from the outlets is to raise the tail water level. In this research, a flow partitioning structure, FPS, designed, carried out, and installed downstream a sluice gate to apportion the cross sectional area of the flow and, then, increase the resistance of the friction force by increasing the walls of flow. The FPS shaped as a sectioned triangular prism consists of sets of 2.6cmÃ—2.6cm iron square-section pipes formed with direction of the flow. The FPS with a vertical front face consisting of 16Ã—11, rows Ã— columns, of pipes extended 10cm downstream and held by a 0.5cm, thickness, iron bars and welded together to prevent any egression of the pipes from the FPS. This combination of the pipes and bars made a width of 29.6cm and height of 42.6cm to fit, approximately, the flume cross sectional area dimensions. The downstream face made with an inclination of 45o to prevent the free fall of the water. The system (which consists of a sluice gate, FPS, and rising weir) installed in a horizontal flume of 0.3m width, 0.45m depth, and 15m length. The system operated with flow rates ranged from 11.11 to 36.24l/s with different gate openings in 27 tests. In each test, the hydraulic jump formed downstream the sluice gate and the FPS once placed downstream the jump and once removed, in the same test, with maintaining the same flow conditions, and measurements are taken to investigate the effect of the FPS on the jump. The results show that the additional friction resistance by the FPS increased the tail water level and forced the hydraulic jump towards the sluice gate, in which the FPS produced a converging distance ranged from 0.64m to 5.34m. This convergence of the jump lowered the head losses of the flow before the jump and then increased Froude Number, Fr, and produced higher y2/y1 value. The increased value of y2/y1 increased the energy dissipation of the jump, in which the jump produced energy dissipation ranged from 8.47 to 85.38% with the existence of the FPS instead of 5.91 to 66.14% without it, with same flow conditions. In spite of the considerable increase in the tail water level downstream the FPS, there was no significant differences of the dissipated energy with and without the FPS for the whole system, in which the energy dissipation ranged from 14.05 to 55.91% with the FPS and ranged from 13.57 to 55.09% without it.

Published: June 2023

This study aims to apply Water Quality Index (WQI) to evaluate quality of groundwater samples collected from Basrah governorate south of Iraq. The samples were collected from (29) wells located in different districts of Basrah governorate (Safwan, Zubair, and Um-Qasr) during Summer Season of 2015. The groundwater samples were analyzed for pH, electrical conductivity, total dissolved solids and other major ions. For calculating WQI, eleven parameters; pH, EC, TDS, Total hardness as CaCO3, Calcium, Magnesium, Sulphate, Chloride, Nitrate, Sodium, and Potassium have been considered. The suitability of groundwater in the study area for human drinking purpose was achieved by WQI depending on guideline values of World Health Organization (WHO 2011) for chemical parameters. Then, the weights (Wi) were assigned to the parameters based on their influence on human health. The results showed that the (WQI) values for the groundwater of study area varied from poor to unsuitable for human drinking purpose.

Published: June 2023

As human communities grow larger and larger, the problem of waste management becomes one of urgent need that should be solved. Recycling and reusing of the waste materials is an efficient measure in management of the waste materials, which in addition to preventing the pollution, it conserves natural resources. Plastic bottles made of polyethylene terephthalate (PET), constitutes a major fraction of household wastes. They are classified as non- biodegradable waste materials which are harmful for public health. So making use of PET in concrete production can be useful method to get rid of plastics solid waste damage on environment. In this research, effect of using waste PET that was converted to granules in concrete has been studied experimentally. Different proportion of sand ranging from 1% to 8%, were replaced by granulated plastic. The resulting concrete was compared with normal concrete without any addition of granulated plastic. Then the specimen were tested at 7 and 28 days after curing, and some engineering properties of the mixtures including slump test, fresh and dry density, compressive, and slip strength have been investigated. Analyzing experimental results of this work indicated that optimum dosage of waste bottles replacement is 2% as fine aggregate- substitution aggregate to get maximum compressive strength and slip strength.

Published: June 2023

Background: Previous studies on bone mineral density (BMD) abnormalities associated with hypothyroidism are scarce and not conclusive. The effect of thyroid hormone therapy on BMD has shown mixed results. Aim: This study aimed primarily to determine the association between the positive history of levothyroxine administering and the risk of osteoporotic fracture in Jordanian cohort of both genders, including post-menopausal women, who were attended to our rehabilitation clinic. Methods: This study trial was an observational study, which was conducted retrospectively at Prince Rashid bin Al-Hasan Military Hospital, Royal Medical Services, Irbid, Jordan. The Binary Logistic Regression (BLgR) analysis was conducted for the 2 contrarily Levothyroxine (Tx) comparative group; Tx dependent cohort (Cohort II) versus Non-Tx dependent cohort (Cohort I), against the probability of being on the higher (versus lower) risk of femoral hip osteoporotic fracture (fHOPF). The studied patients were dichotomously categorized into 2 comparative cohorts; non-Levothyroxine dependent cohort [Cohort I] versus Levothyroxine dependent cohort [Cohort II]. A Chi Square test was processed across these 2 dichotomized cohorts to express the comparison results as Number (Percentages), strength of associations (odd ratios), Pearson chi-square statistic (χ 2), Goodness of Fit (G-Test of independence), and Pearson (r) and Spearman (ρ) correlations. Results: The BLgR analysis results revealed that the unadjusted risk ratio for the higher probability of fHOPF in our investigated patients, who were on Thyroxine therapy [Tx dependent cohort, Cohort II] compared to the Tx independent cohort [Cohort I], was 10.969 (95% CI; 4.615-26.072). The explained variations in the fHOPF risk related Tx dependent status on our model of this BLgR based model ranged from 17.9%-23.8% (depending on the inferential Cox & Snell R2 or Nagelkerke R2 methods, respectively) and correctly classified approximately 61.2% of the overall cases. The constructed BLgR model was formulated as {e (-0.627+2.395×Tx)/[1+ e (-0.627+2.395×Tx)]}. Conclusion: We revealed that the patients who were used thyroxine therapies (Cohort II patients) had significantly higher proportional distribution of higher risk of fHOPF compared to Cohort I patients [41 (85.4%) vs 55 (34.8%), respectively] with an odd ratio of 10.969 (95% CI; 4.62-26.07) and significant positive correlation of 0.429±0.057, χ2=37.889, p-value=0.000.

Published: June 2023

Abstract. The position of pastor often brings its own psychological burden to their children. They often face excessive expectations related to their parents' position. As a result, pastor's children may experience stress or even have lower life satisfaction compared to their peers whose parents are not pastors. Some even start doubting their Christian faith and no longer call themselves Christians. This paper aimed to show how the narrative approach applied in pneumatological counselling can help pastors' kids to establish their unique position and role as pastors' kids. The method used in this study was a literature study. Through this study, it was found that the narrative approach in pneumatological counselling helps to construct a new narrative so that pastor children can understand themselves well, apart from the narrative that has been constructed by their environment.Abstrak. Jabatan sebagai pendeta kerap kali membawa beban psikologis tersendiri bagi anak-anak pendeta. Mereka seringkali menghadapi ekspektasi yang berlebihan terkait dengan jabatan orang tuanya. Akibatnya, anak pendeta bisa mengalami stres atau bahkan memiliki kepuasan hidup yang lebih rendah dibandingkan dengan teman-temannya yang orang tuanya bukan pendeta. Beberapa bahkan meragukan iman Kristen mereka dan tidak lagi menyebut diri mereka Kristen. Tulisan ini bertujuan untuk menunjukkan bagaimana pendekatan naratif yang diterapkan dalam konseling pneumatologis dapat membantu anak-anak pendeta untuk membangun posisi dan peran mereka yang unik sebagai anak-anak pendeta. Metode yang digunakan dalam kajian ini adalah studi pustaka. Melalui kajian ini diperoleh hasil bahwa pendekatan naratif dalam konseling pneumatologis membantu menyusun narasi baru sehingga anak-anak pendeta dapat memahami dirinya sendiri dengan baik, lepas dari narasi yang selama ini dikonstruksi oleh lingkungannya.

Published: June 2023

The paper presents a review of the seismicity of the southern part of the Russian Far East in 2022 based on the data from the catalog of the “Yuzhno-Sakhalinsk” Regional Information Processing Center of the Sakhalin Branch of the Federal Research Center "United Geophysical Survey of the Russian Academy of Sciences". The main parameters of the seismicity, such as the statistical estimation of seismicity level SESL'09, Benioff diagrams, density maps of conditional elastic deformation in 2022 compared to the previous longer time interval, are estimated. A brief analysis of the most significant and interesting earthquakes for detailed study is given. The seismicity of the Kuril-Okhotsk, Sakhalin and the Amur and Primorye regions in 2022 remained within the background values. At the same time, seismic activation was noted in the Sakhalin region, manifested in a number of moderately strong events on the northeastern shelf, in the Uglegorsky district, north of the Schmidt Peninsula, as well as a strong mantle event in the La Perouse Strait with Mw = 5.9. The strongest earthquake of the Kuril-Okhotsk region with Mw = 6.0 occurred in the southern part of the Kuril Island arc. A long series of moderately strong events in the Middle Kurils with Mw up to 5.6 attracts attention. The problem of operational processing of earthquakes in the Amur region and Primorye due to the decreasing number of seismic stations in this region is noted, as well as the systematic underestimation of the energy characteristics of deep-focus earthquakes.

English teachers often face confusion to relate between the materials and religious values especially teachers of Islamic school who should strongly show the relation. This paper aims to develop a teaching prototype as a guideline leading to the integration of religious values into English lesson for Islamic Junior High School.  Design-based research was used as research method in which need analysis was initially done for gaining EFL teachers’ reflection and aspiration on their English class, and their understanding on integration of Islamic values. Three English teachers from both pesantren-based and non pesantren-based were involved as the research subjects. The need analysis was the basis for the prototype which then followed by expert judgment to shape the quality of prototype and future direction for integrated-holistic teaching. The study showed that integrated-holistic teaching for English lessons could cover spiritual, emotional, intellectual, and social dimensions which are very essential for students to be holistic/insan kamil students. In conclusion, English teachers are strongly possible to contextualize  the prototype. Pedagogical implication of the study could be manifested by the existing clear direction for teaching English holistically. This study is not free from limitation. It needs to be more operationalized to potentially build students who are spiritually, intellectually, emotionally, and socially mature.
INFLUENCE OF ABSURD THEATRICAL TRADITION IN MODERN ASSAMESE DRAMA: A COMPARATIVE STUDY WITH REFERENCE TO THE PLAYS OF ARUN SHARMA
Authors: Karim Mohammad Rezaul
Published: June 2023

The contemporary Assamese plays have developed as a result of numerous interwoven influences and channels. And it is clear that western influences were what shaped the Assamese and played into their perfection. After independence, Assamese writers of prose, poetry, and theatre, produced works that were on pace with the period. It demonstrated identical compositional experimentation and sociological analysis. The Assamese plays exhibit a strong western heritage from playwrights like Ibsen, Shaw, Beckett, and other absurd dramatists. A few dramatists, like Dr. Arun Sarma, Ratna Ojha, and Himendrakumar Borthakur made reflections of works of Lonesco and Beckett and despite the fact the impact of absurd dramas was not very common. In this article, the researcher investigated the works of the most renowned and esteemed Assamese playwright, Dr. Arun Sarma (1964), to emphasize the distinguishing components and similarities of Shri Nibaran Bhattacharya and Aahaar with those of absurd dramatic tropes. The researcher discovered, using the comparative technique of analysis, that, despite frequent assertions to the contrary, Aahaar has much in common with the absurdist movement, whereas Shri Nibaran Bhattacharya cannot be regarded as a fully-fledged absurd drama.

Published: June 2023

The article presents the results of studying potato accessions according to the accumulation and morphological properties of starch in tubers in the nursery of dynamic testing in agroecological conditions of the Kirov region (Volga-Vyatka region) in 2022. The objects of the research were 11 new hybrids bred by the Falenki Breeding Station – branch of the Federal Agricultural Research Center of the North-East named N.V. Rudnitsky. The early-maturing variety Udacha, the middle-early variety Nevsky, and the mid-season variety Chaika were used as standards. There have been identified hybrids with increased starch content (19 % and higher) on the 80th day of vegetation: early-maturing 172-13, medium-early – 165-00, 27-07, 13-18, mid-season – 182-13, 580-13, 252-18. The hybrids of the middle early group had the largest average size of starch grains: 165-00 (34.3±2.6 microns), 132-18 (36.0±3.0 microns), 233-12 (39.2±3.3 microns). Most of the hybrids had starch grains of regular rounded shape, accessions 233-12 and 232-12 – mostly irregular (angular) shape. In the course of the research, it was found that storing potatoes at the temperature of 3...4 ° C led to a decrease in the fraction of starch grains of very large size: in early-maturing varieties from 9.2 to 2.7 %, in middle early – from 13.5 to 5.0 %, in mid-season – from 9.6 to 3.2 %, which was due to starch resynthesis. As a result of the breeding work, promising potato hybrids of various maturation periods have been identified for transfer to state variety testing with improved agronomic traits, including high potential productivity: early-maturing 172-13, middle-early 233-12, mid-season 182-13 and 580-13.
The influence of hydrothermal conditions of the Kirov region on the productivity and quality of grain of spring soft wheat varieties of different ripeness groups
Authors: Volkova L. V.
Published: June 2023

Meteorological conditions were monitored for the period "May-August" in the Kirov region (Volga-Vyatka region) from 2008 to 2022. An increasing trend of the sum of precipitation and hydrothermal coefficient (НTC) values and a descending trend of the sum of effective temperatures was established. By the example of early-ripening (Iren, Bazhenka) and middleripening (Priokskaya, Simbirtsit, Margarita, Kamenka) varieties of spring wheat, the level and direction of variability of the main agronomic traits by changing the values of the НTC have been determined. In early-maturing varieties with an increase in the НTC of the growing season the content of protein and gluten in the grain significantly decreased, and the following increased: yield, duration of vegetation, plant height, ear density, mass of 1000 grains, density of the productive stem, the nature of the grain and the indicator of the gluten index. The elements of ear productivity were maximally expressed in the years optimal in terms of moisture. The reaction of medium-ripened varieties was similar according to the greater number of traits, except for the number of grains per ear, the weight of the grain per ear and the plant, the nature of the grain. By means of the correlation analysis, the influence of meteorological factors on the development of traits of spring wheat both for the entire growing season and for individual months has been studied. A high dependence of the duration of the growing season and the protein content in the grain on the sum of effective temperatures for May-August (r = 0.64...0.77) was revealed. The amount of precipitation made a significant contribution to the formation of traits only in critical phases of plant development. The analysis of regression equations obtained using 11 variables (weather factors by months) with a time sample size of 15 years showed that an increase in the amount of precipitation in June by 10 mm led to an increase in yield by an average of 0.13...0.14 t/ha, and a decrease in the average daily temperature of August by 1 °C provided an increase in yield by 0.23...0.26 t/ha. The duration of the growing season decreased in June by 2.2...2.4 days with 1 °C increase in the average temperature; in July – by 2.3...3.0 days; in August – by 1.3 days. The protein content in the grain most of all depended on the average daily temperature in June, with of 1 °C increase the amount of protein raised by 0.85...0.87 %.

Published: June 2023

The yield and quality parameters of potato tubers of Gala variety were determined in the conditions of the Middle Urals in 2020 and 2022 in long-term stationary experiment after prolonged application of NPK increasing rates (30-60-90-120-150 kg a.i.). The application of NPK by 60 kg a.i./ha and more promoted the potato yield raise by 1.1-1.3 times in 2020 and by 1.3-1.5 times in 2022 compared with the control variant without fertilizers (21.4 and 14.4 t/ha by years, respectively). The lowest dry matter content over the years of research was noted at the maximum dose of N150P150K150 mineral fertilizer in the experiment– 15.6 % in favorable weather conditions of 2020 and 19.4 % in the dry 2022. The starch content in potato tubers did not depend on the dose of applied mineral fertilizers and varied in 2020 in the range from 11.1 to 13.8 %, in 2022 – from 14.4 to 16.3 %. In potato tubers the content of crude protein in the wet mass increased from 1.32 to 1.90 % in 2020 and from 1.80 to 2.65 % in 2022 to the weight of wet mass with an increase in the dose of NPK from 30 to 150 kg/ ha active substance. The sugar content in 2020 was 0.58-0.83 % for natural humidity, in 2022 – 0.23-0.47 %. The fiber content in potato tubers did not depend on the doses of applied mineral fertilizers. The application of increasing doses of NPK did not lead to exceeding the permissible value of the nitrate content in fresh potato. According to a comprehensive assessment of the quality of tubers, potato yield, obtained under given conditions, was suitable for the production of low carbohydrate potato products and for fodder purposes.

Published: June 2023

The direction of the breeding process in herds and populations of dairy cattle breeds based on the actual indicators and variability of the trait is one of the main factors that allows to determine the effectiveness of breeding measures. As the initial material for the research there were taken the data of breeding records (n=681) of Ayrshire breed cows of the agricultural complex "Maysky" of the Vologda region. The number of cows was distributed by generations (195 cows with the first incomplete lactation, 177 cows with the first completed lactation, 130 cows for the second lactation, 179 cows for the third lactation and older). According to the research results, the superiority of the actual indicators for the live weight of heifers in animals of modern generation in early age periods was from 28 to 39 kg. Consequently, with each new generation, animals have better development indicators, as evidenced by the indicators of variation (variability) of the live weight of heifers in the early age periods of weak and moderate Cv = 5.3 to 10.6 %, depending on generation. The reduction of the age of the first insemination of heifers to 13.4 months (-2.2 months) and the first fruitful insemination to 14.0 months (-2.1 months) in animals from full-age to the first incomplete lactation was revealed. A targeted selection of cows was carried out in the herd according to the level of milk productivity of mothers after the first lactation - the selection efficiency was 977 kg of milk, according to the highest - 456 kg. The selection of breeding bulls was carried out according to the level of productivity of the breeding stock, however, it should be noted that the intensity of selection in cows for the incomplete first (10968 kg of milk) and first lactation (10635 kg of milk) is reduced compared to cows for the second lactation (11417 kg of milk). Consequently, in herds and populations of dairy cattle breeds, in order to achieve genetic progress in productivity in the next generation, it is necessary to determine the direction of the breeding process.

Published: June 2023

The purpose of the research is to study the composition of biologically active compounds of the experimental biological supplement Fitostimplus and its influence on the biochemical parameters of the blood of calves of the milk growing period, body weight gain, safety. In the experiment Holstein calves starting from the age of 3 days were used during 2 months. The results of studies of the phytobiotic for the presence of biologically active substances showed that it contained 13 different flavonoids and their glycosides, 7 ecdysteroids. As the main flavonoids there were identified luteolin, quercetin, quercetin-3-methyl ether, apigenin, kaempferol, and as ecdysteroids - ecdysten, inocosterone and augasterone C. The total concentration of the studied extractives (flavonoids, ecdysteroids) in terms of dry product corresponded to 3.594 mg/g. The concentration of lactic acid microorganisms in Phytostimplus was 4×106 CFU/g. In the experiment on calves (n = 5 per group) it was found that after daily oral administration for 60 days Phytostimplus in doses of 1.0; 2.0; 3.0 grams per head, the average daily gain in live weight in the experimental groups exceeded that in the control by 6.3-27.7 %. The best indicator of the average daily gain in live weight of calves was noted with the introduction of 2.0 and 3.0 grams (27.7 and 18.2 % higher than in the control, respectively), safety in all groups was 100 %. A month after the start of the experiment, the phosphorus index in the blood of calves in all experimental (from 3.1±0.07 to 3.4±0.02 mmol/l) and control (3.1±0.01 mmol/l) groups exceeded reference values by 6.9-17.2 %. At the end of the experiment, the phosphorus index in the experimental (from 2.7±0.22 to 2.8±0.07 mmol/l) and control (2.6±0.01 mmol/l) groups returned to normal. Glucose in the experimental and control groups (from 5.3±0.2 to 5.9±0.1 mmol/l) was 15-28.2 % higher than the reference values. Other studied biochemical parameters in the experimental groups: ALT (from 13.4±1.6 to 19.9±2.2 units/l), AST (from 56.3±3.2 to 63.3±4.8 units/l), total protein (from 62.0±0.1 to 65.0±0.1 g/l), albumins (from 39.3±1.4 to 41.5±2.4 g/l), creatinine (from 64.8±3.5 to 72.8±6.6 µmol/l), urea (from 2.7±0.16 to 3.6±0.3 mmol/l)– did not go beyond the physiological norm. Thus, by the end of the experiment, Phytostimulus contributed to an increase in the average daily gain of calves in comparison with the control. The effective doses of Phytostimplus for calves of the milk growing period were established, which, in terms of the main substance, corresponded to 2-3 g/head per day.

The object of the research were calves aged 120 days, which were divided into three groups: control, and two experimental groups - with a difference in using or the absence of phytosorbent. The diet included cereal hay and compound feed (CP 21.5%) according to the norms and regimen of feeding, for animals of this age. It appeared that for calves shortening of the adaptation period to the consumption of a large amount of compound feed had a negative impact on the rumen contractile function and the processes of digestion in it with the formation of a complex of symptoms of frothy tympany and rumen acidosis. After a course of appropriate treatment, the specific symptoms of these pathologies of the rumen disappeared, but the imbalance between the depression of symbiotic and activation of abdominal digestion remained, with the formation of a constant pre-threshold level of local autointoxication. The transfer of animals to the technological diet activated the processes of rumen metabolism and increased biochemical imbalance, which caused the progression of the endogenous intoxication syndrome and vegetative dystonia with a corresponding increase in the risk of developing respiratory and gastrointestinal pathologies. The use of a combined native premix based on the enterosorbent Rigatirin against the background of residual pathological phenomena after proventriculus dysfunctions reduced the level of toxic substances in the rumen, which excluded the generalization of autointoxication with an increase in the functional load on the digestive organs. As a result, the mechanism of pathogenetic integration (predisposition) formation in the body was leveled with a corresponding decrease in the incidence of the lungs, rumen and intestines. As a result, the mechanism of pathogenetic integration (predisposition) formation in the body was leveled, which caused a 6.7-fold decrease in the level of morbidity in animals and a 22.9 % increase in their growth.

About 40% of the primary energy in the building sector is consumed for heating and cooling applications, where it started by relying on the use of sustainable energy sources through using an Earth tube heat exchanger (ETHE). ETHE is apparatus that works to transfer heat from ambient air to underground and vice versa which is used in heating and cooling applications. ETHE depends on undisturbed subsoil temperature, where the underground temperature doesn't change through the year at a certain depth. Ambient air passes through the buried heat exchanger in the ground and then cools down in summer and warms in winter. The good performance of this system depends on design efficiency. This paper reviews the experimental and numerical researches of ETHE which focuses on its design. The use of geothermal energy through ETHE leads to meeting energy demand and preserving the environment by reducing carbon dioxide emissions, which in turn affects the ozone.

Designing an aircraft involves a lot of stages, however, airfoil selection remains one of the most crucial aspects of the design process. The type of airfoil chosen determines the lift on the aircraft wing and the drag on the aircraft fuselage. When a potential airfoil is identified, one of the first steps in deciding its optimality for the aircraft design requirements is to obtain its aerodynamic lift and drag coefficients. In the early stages of trying to select a candidate airfoil, which a whole part of the design process rests on, the conventional method for acquiring the aerodynamic coefficients is through Computational Fluid Dynamics Simulations (CFDs). However, CFD simulation is usually a computationally expensive, memory-demanding, and time-consuming iterative process; to circumvent this challenge, a data-driven model is proposed for the prediction of the lift coefficient of an airfoil in a transonic flow regime. Convolutional Neural Networks (CNNs) and Multi-Layer Perceptrons (MLPs) were used to develop a suitable model which can learn a set of usable patterns from an aerodynamic data corpus for the prediction of the lift coefficients of airfoils. Findings from the training revealed that the models (MLPs and CNNs) were able to accurately predict the lift coefficients of the airfoil.

Rusya’nın 2022’de Ukrayna’yı işgali, uluslararası ilişkileri birçok açıdan etkilemektedir. Bu nedenle, işgal, uluslararası ilişkiler yazınında birçok açıdan ele alınmaktadır. Diğer taraftan, yazında, işgalin uzay çalışmalarını nasıl etkilediğini inceleyen herhangi bir çalışma bulunmamaktadır. Makalenin amacı, Rusya’nın Ukrayna işgalinin uzay çalışmalarını nasıl etkilediğini açıklamaktır. Bu nedenle, yazında ilk olma özelliği taşımaktadır. Makalenin teorik çerçevesi, İngiliz Okulu’nun teorik ilkelerine dayanmaktadır. Makalenin metodolojisi ise iki aşamalıdır. İlk olarak, aktörlerin açıklamaları ve yaptırımları örneklendirilmektedir. İkinci olarak, bu açıklamalar ve yaptırımlar uzay çalışmaları açısından incelenmektedir. Bu bağlamda; makale, “İngiliz Okulu’nun fikirleri nelerdir?”, “Uzay çalışmaları açısından işgalden önceki durum nedir?”, “İşgal nasıl başlamıştır?”, “Tarafların, uzay çalışmalarına yönelik açıklamaları ve yaptırımları nelerdir?” ve “İşgal, uzay çalışmalarını nasıl etkilemiştir?” soruları temelinde bölümlendirilmiştir. Değerlendirme sonucunda, Rusya’nın Ukrayna işgali nedeniyle uzay çalışmalarında rasyonalizmden realizme ve uluslararası toplumdan uluslararası sisteme geçiş yaşandığını belirtmek mümkündür.

Published: June 2023

Researchers need to identify the nephrotoxic properties of medicinal products both during preclinical development and when exploring options to optimise pharmacotherapy. The main challenge is to find an experimental model for assessing drug-induced nephrotoxicity that reflects in vivo conditions as closely as possible.

The aim of the study was to compare the susceptibility of HEK293 and RPTEC cell lines used as experimental models for assessing the nephrotoxicity of cefuroxime and cefepime.

Materials and methods. The study investigated HEK293 and RPTEC cell lines cultured on plates with 0.4 µm pore membrane inserts. The cell lines were incubated for 3 days with cefuroxime and cefepime (cephalosporins excreted primarily by the kidneys). The medicinal products were added to the basal part of the well at concentrations of 50 and 150 µg/mL (cefuroxime) or 30 and 120 µg/mL (cefepime) twice a day. After incubating the cells with cefuroxime and cefepime for 24, 48, and 72 hours, the authors determined the expression levels of the SLC22A6 and SLC22A8 genes encoding organic anion transporters by a reverse transcription polymerase chain reaction. The authors considered caspase 3 and caspase 7 activation indicative of the nephrotoxic effect of cephalosporins; they evaluated this indicator by a fluorometric assay after 24, 48, and 72 hours of incubation.

Results. According to the study, the expression of the SLC22A6 and SLC22A8 genes decreased with cephalosporin transport in both cell lines. The decrease occurred in the RPTEC cell line earlier than in the HEK293 cell line. The authors observed caspase 3 and caspase 7 activation only in the RPTEC cell line after incubation with cefuroxime and cefepime at low concentrations (50 and 30 µg/mL, respectively) for 72 hours and at high concentrations (150 and 120 µg/mL, respectively) for 24 hours.

Conclusions. The RPTEC cell line exhibits higher susceptibility to cefuroxime and cefepime toxic effects than the HEK293 cell line due to higher transporter gene expression. Higher cephalosporin concentrations accelerate caspase 3 and caspase 7 activation in the RPTEC cell line. The experimental model based on the RPTEC cell line is a promising tool for the analysis of the nephrotoxic properties of a wide range of medicinal products.

Several treatment regimens with antituberculosis medicinal products are available for tuberculosis. Thiozonide is a newly developed original antimicrobial agent that exhibits bacteriostatic activity against Mycobacterium tuberculosis strains H37Rv, CN-37, CN-40, and MS-115.

The aim of the study was to investigate the embryotoxic, foetotoxic, and teratogenic effects of thiozonide in pregnant rabbits.

Materials and methods. The study involved 66 pregnant rabbits (4 groups of 16–17 animals each). The rabbits received oral thiozonide from day 6 to day 19 of gestation at doses of 20.6 mg/kg (1 TD (therapeutic dose)), 103 mg/kg (5 TDs), and 206 mg/kg (10 TDs). The control group received a 1% starch solution. The authors conducted a macroscopic examination of the reproductive organs and a histological evaluation of the placenta in eutha nised pregnant rabbits. Live foetuses underwent a check for developmental abnormalities, a skeletal development evaluation with a modified Dawson’s method, and a histologic examination of the internal organs.

Results. The study showed no clinical signs of toxicity and no mortality associated with thiozonide in pregnant rabbits across all dose groups. Macroscopic and histological examinations revealed no pathological changes in the reproductive organs of pregnant rabbits. The evaluation of embryotoxic and foetotoxic effects did not identify any differences between the foetuses of the animals assigned to different doses of thiozonide and the control group. The authors found no developmental abnormalities in the foetuses. Examinations of foetal skeleton development and internal organ condition identified no differences between the groups and no abnormalities. The authors registered the death of all foetuses (late resorption) in one rabbit from the 206 mg/kg group. Therefore, the 103 mg/kg dose (5 TDs) was selected as a reasonable No Observed Adverse Effect Level (NOAEL).

Conclusions. Thiozonide has no embryotoxic, foetotoxic, or teratogenic effects.

The results of theoretical and experimental studies of near-field microwave tomography of inhomogeneities in the parameters of relative blood content and air filling of the lungs are presented. Methods and algorithms for solving inverse problems of 3D tomography of the mentioned parameters of the lungs are proposed based on the data of pulse and multifrequency multisensory measurements of the scattered signal, as well as on the basis of the multi-position application of the previously developed 1D tomography (profiling) method. An experimental study of this method was carried out: based on the data of sequential bistatic measurements of the parameters of a scattered ultra-wideband pulse signal in a two-dimensional (square) region of the chest, a three-dimensional tomographic distribution of air content in the lungs in the inhalation phase was obtained.
The Minsk Accords and the Political Weakness of the “Other Ukraine”
Authors: Ishchenko Volodymyr
Published: June 2023

The article discusses the political contention around the implementation of the Minsk Accords in Ukraine, and why the pluralist nation-building project required for the success of these accords failed. The much-debated cleavage between the more ‘pro-Western’ and more ‘pro-Russian’ regions of Ukraine requires that such an alternative be taken seriously. The article argues that neither the change of the balance in favor of the pro-Western electorate in 2014, nor the rise of Ukraine’s civic identity in response to Russian aggression can adequately explain the failure to develop a positive, pluralist nation-building project in the context of Minsk. It argues instead that the profound class and political asymmetry between Ukraine’s ‘Western’ and ‘Eastern’ political camps created different capacities for the universalization of their particular interests, and for effective political mobilization for and against the Minsk Accords in the context of Euromaidan’s revolutionary dynamics.
