Published: May 2021

Mathematical modeling and computer simulation methods have been used to investigate the extent of influence exerted by bio-clogging on the dynamics of excess head scattering in the soil massif. To this end, the classical equation of filtration consolidation has been modified for the case of variable porosity resulting from changes in the biomass. The numerical solution to the constructed mathematical model in the form of a nonlinear boundary problem was derived by a finite-element method. Numerical experiments were carried out and their analysis was performed. Specifically, this paper shows the charts of pressure differences in the soil array when neglecting bio-clogging and when estimating the effects exerted by bio-clogging at specific points in time. The numerical experiments demonstrated that in two years after the onset of the consolidation process in the neighborhood of the lower limit of the examined soil mass with a thickness of 10 meters, excess heads fall from the initial value of 10 m to 4 m. The greatest impact from the clogging of pores by microorganisms is revealed in the neighborhood of an upper limit. At a depth of 1 m, at t=180 days, the pressure difference reaches 2.4 m. This is about 200 % of the pressure distribution without taking into account the effects of bio-clogging. Over time, the effect of bacteria on the distribution of pressures in the neighborhood of the upper boundary decreases. However, this effect extends to the entire soil mass, up to the lower limit. Thus, at t=540 days, at the lower limit, the effect of bio-clogging leads to that excess heads are 1.8 m greater than for the case of pure water filtration (a relative increase of about 80 %).
Bio-clogging processes are intensified as a result of the development of microorganisms when organic chemicals enter the porous environment. Therefore, from a practical point of view, studying them is especially relevant for household waste storage facilities and the stability of their soil bases. It is advisable to undertake research by using the methods of mathematical modeling and computer simulation
Devising a procedure to form the diagnostic parameters for locomotives using a principal components analysis
Authors: Bodnar Borys , Ochkasov Oleksandr 
Published: May 2021

Modern diagnostic systems are characterized by that the flow of diagnostic information requires significant computational resources to process. In order to improve the reliability of the object to be diagnosed and reduce operating costs, it is necessary to improve procedures for analyzing diagnostic results. This paper suggests a procedure to form the diagnostic features of locomotive nodes based on the use of a principal components analysis. The proposed approach is distinguished by a decrease in the dimensionality of the input set of diagnostic features in order to select the sets of interconnected diagnostic parameters. Based on the selection of the sets of interconnected diagnostic features, constructing new latent diagnostic parameters has been proposed. A latent diagnostic parameter contains information that combines data from several initial diagnostic features. The result of the method is a set of latent diagnostic parameters that do not correlate with each other and reflect the behavior of the object to be diagnosed from different technical points. The application of a sufficient number of latent diagnostic parameters involved the scree test method. This paper reports the results from using the proposed approach for treating the results from diagnosing the hydraulic transmissions in locomotives. The result from applying the procedure has made it possible to propose using three latent diagnostic parameters to assess the technical condition of a locomotive’s hydraulic transmission during bench tests. The suggested parameters contain 90 % of the original information and reflect losses in the transmission, as well as the load at the input and output of the transmission.

Published: May 2021

The aim of the work was to study the monosaccharide composition of WSPS, PS and HC, isolated from the raw materials of Camelina sativa and Camelina microcarpa and to establish the quantitative content of these fractions.
Materials and methods. The analysis of the composition of biologically active substances of carbohydrate nature was carried out in herb and seeds of Camelina sativa (variety “Slavutych”) and Camelina microcarpa. Samples of seeds for growing plants were provided by the National Center for Genetic Resources of Plants of Ukraine (The Plant Production Institute ND. V.YA. YURIEVA, NAAS of Ukraine).
For the studies, the carbohydrates were separated by the Bailey method into monosaccharide fractions, which were used for TLC and quantification using a modified Dreywood spectrophotometric method with anthrone reagent in concentrated sulfuric acid.
Results. The presence of glucose, galactose and arabinose was determined in the hydrolysates of polysaccharide fractions of Camelina sativa of herb and seeds. Galactose, glucose, arabinose and xylose were found in the hydrolysates of polysaccharide fractions of Camelina microcarpa herb and seeds. The highest content of WSPS was determined in the herb of Camelina sativa, and the lowest - in the seeds of Camelina microcarpa. PS in the largest number were also found in the herb, and in the smallest – in the seeds of Camelina sativa. The content of the amount of HC was the highest in the herb of Camelina sativa, and the smallest – in the seeds of Camelina sativa.
Conclusions. The presence of 3 monosaccharides in the raw material of Camelina sativa and 4 monosaccharides in the raw material of Camelina microcarpa was established by TLC. The quantitative content of monosaccharide fractions was determined by the spectrophotometric method, which in total predominated in Camelina sativa

The aim: to investigate the effect of a new derivative of 4-aminobutanoic acid (compounds KGM-5) on the level of neurotransmitters and neurotransmitter amino acids and the structural-functional state of the hippocampus of rats with acute cerebrovascular accident (ACVA).
Materials and methods. ACVA was reproduced in rats by occlusion of the left carotid artery under anesthesia (sodium thiopental (35 mg/kg) intraperitoneally (i/p). 5 groups of animals were used: intact control (IC, n=6), untreated animals with ACVA (CP, n=13); animals with ACVA (n=14), which were treated for 5 days with KGM-5 at a dose of 30 mg/kg i/p, animals with ACVA (n=13), who received i/p comparison drug “Picamilon” (17 mg/kg). There was a group of pseudo-operated animals (POA, n=8). Withdrawal of animals from the experiment was performed on day 6 after modeling ACVA by painless euthanasia under anesthesia. Histological examinations of CA1 and CA3 zones of the ventral hippocampus were performed with staining of sections with thionine by the method of Nissl and hematoxylin, eosin. In the rat brain, neurotransmitter amino acids and neurotransmitters were identified. Statistical processing was performed using the W-Shapiro-Wills test to verify the normality of the distribution and the nonparametric Mann-Whitney U-test. The accepted significance level is p<0.05.
Results. Under the influence of the compound KGM-5 and “Picamilon” in the CA1 zone of the hippocampus, the number of normochromic neurons increased by 20 % and 16.6 %, respectively, hyperchromic pycnomorphic neurons and shadow cells decreased respectively by 5.8; 2.9 times and 6.3; 3.5 times, the index of alteration of neurons decreased by 6 times and 4.8 times, respectively, the area of ​​the perikaryon of these neurons increased by 39.7 % and 77.8 %, respectively, compared with KP (p<0.05). Both studied agents showed a less pronounced normalizing effect on the CA3 area of the hippocampus. The new compound KGM-5 showed a normalizing effect similar to “Picamilon” on the level of neurotransmitter amino acids and neurotransmitters in the brain of rats with ACVA.
Conclusions. Therapeutic administration of KGM-5 increases the survival of ventral hippocampal neurons, reducing the relative proportion of irreversibly altered cells, and helps to restore impaired levels of neurotransmitter amino acids and neurotransmitters in the brain of rats with ACVA.
The neuroprotective effect of the new compound KGM-5 corresponds to this comparison drug “Picamilon”

The aim. The aim of the work was to study the indicators of spermatogenesis in the lake frog, Pelophylax ridibundus (Pallas, 1771), in the zone of the influence of emissions from the Burshtyn Thermal Power Plant (TPP).
Materials and methods. Urinal sperm and testes samples were taken from male frogs under conditions of anthropogenic pollution (Burshtyn industrial area). Such parameters as sperm concentration in ejaculate, the number of live spermatozoa, total amount of actively mobile forms, and percentage of spermatozoa with progressive motion were determined by calculations in the hemocytometer. Testis samples were processed for routine histological method. The diameter of seminiferous tubules and histological abnormalities were studied.
Results. Studies have revealed that near the Burshtyn TPP industrial site, the sperm concentration in the sperm sample and the total number of motile spermatozoa of the lake frogs significantly decreased. The number of dead spermatozoa increases. Amphibians from polluted sites had histological abnormalities in testes such as dilation of the seminiferous tubules with sparse sperm. At the same time, the diameter of the seminiferous tubules in the animals from polluted site significantly decreased.
Conclusions. The impact of the emissions from the Burshtyn thermal power plant has an expressive reprotoxic effect that is manifested by depressive changes in testes tissue and gametes. The reproductive system of the lake frog is quite sensitive to environmental pollution. Sperm parameters and histological changes in testes are informative biomarkers and can be used for bioindication of technogenically transformed territories

Authors: Ganzha Dmitro , Ganzha Dmytro , Sploshnoy Borys 
Published: May 2021

The aim is to improve the beta-radiometric method of quantitative indication of the content of 90Sr and 137Cs in the counters of plant samples.
Material and methods. In the Chernobyl exclusion zone (ChEZ) in 2017, 2019, leaves of silver birch, black poplar, common reed, sedge were selected, which were dried, crushed, and used as calculating samples for beta radiometry and spectrometry. For measurements, a combined KRK-1 radiometer and a SEB 01-150 spectrometer beta-radiation energy were used.
Results. Currently, in plant samples from the ChEZ, the following are widespread: natural 40K, the concentration of which is usually less than 1 % in relation to the concentration of technogenic radionuclides 90Sr+90Y and 137Cs, therefore, when measuring 90Sr and 137Cs, beta radiation of 40K can be ignored. The measurements were carried out without a spectral filter and using a thin molybdenum filter. Without filter – show the count rate of 90Sr+90Y and 137Cs radiation. The filter transmits 2–3.5 % of the low-energy beta radiation of 90Sr and 137Cs and more than 95 % of the high-energy 90Y. The ratio of the count rate of 90Y pulses with and without filter is 2.14. The 90Sr concentration in the samples was determined from the results of measurements of 90Y, and 137Cs – through the fraction of the counting rate, which remains after deducting 90Sr+90Y. Comparison of the concentration of radionuclides measured by the method of beta-radiometry and spectrometry showed no significant difference between the results obtained by the two methods.
Conclusions. The beta radiometry method for 90Sr and 137Cs provides for measuring the counting rate of beta radiation from counting samples without a spectral filter and using a thin molybdenum filter. Based on the research results, a procedure for calculating the concentration of 90Sr and 137Cs in counting samples of plant leaves was developed

O processamento industrial aumenta a vida útil dos alimentos e confere praticidade aos consumidores. O objetivo do trabalho foi avaliar o perfil e a preferência dos consumidores de alimentos industrializados da cidade de Guanambi/BA, durante o período de março a agosto de 2017. Para o estudo foram realizadas entrevistas com 378 pessoas, usando um questionário de múltipla escolha, conforme tamanho da população, homogeneidade do público-alvo e a quantidade de erro amostral admitida (5%). O consumo de alimentos industrializados foi maior entre o público feminino (75,1%), jovem (33,6%), e em sua maioria, com 2º grau completo (43,7%) e composição familiar entre dois e quatro membros (78,3%). A maioria dos respondentes possuía renda entre um e três salários-mínimos (76,3%). Os consumidores responderam por optar por uma alimentação prática (49,5%), com frequência entre três e cinco dias por semana (32,3%). Os entrevistados disseram consumir alimentos ricos em gorduras, açúcar e sal, entretanto, 80,7% dos respondentes consideraram alimentos industrializados não nutritivos, e a maioria (79,4%) afirmou que deixaria de ingeri-los caso o consumo fosse prejudicial à saúde. Dessa forma, o consumo de alimentos industrializados pode estar associado com fatores culturais, de renda e de disponibilidade de tempos para o preparo das refeições individuais e/ou da família, sendo que o público jovem e feminino apresentou o maior padrão de consumo.

Abstract
The industrial food processing ncreases shelf life and confers convenience to the consumers. This study aimed to evaluate the profile of processed foods consumers in the city of Guanambi-BA from March to August 2017. 378 consumers were interviewed by choosing a multiple-choice questionnaire taken into account population size, target public homogeneity, and sampling error rate at 5%. In Guanambi, that profile revealed on its majority women (75.1%), youngers (33.6%), with secondary education (43.7%), coming from a family size of two to four members (78.3%). Most interviewees earn one to three minimum wages (76.3%). The reason why they choose this kind of food is due to the practicality (49.5%) with a varying frequency of three to five days a week. Interviewees admit consuming food with a high content of fats, sugar, and salt. However, a little over four-fifths (80.7%) consider processed food non-nutritive. Nearly 80% would consider stopping eating them if it were harmful to health. Thus, such consumption may be related to cultural factors, income, and available time to prepare individual and/or family meals, with notably dietary patterns among young and female interviewees.

A research to study the sterilization method and application of Kinetin and IAA to induce the Durian young leaf (Durio zibethinus) in MS medium was conducted in Balai Benih Induk Hortikultura in Salaman Magelang district of Central Java started on September until December 2003. The Laboratory experiment was arranged in two phases, which were the optimation phase of sterilization and induction phase. At the first phase, the sterilization method used was the modification of Mulya (2001) method. The modification use of sterilant, vitamin C antioxidant, Alcohol 70 %, Benlate, Agrept, Tween-20 and Betadine were done to obtain effectiveness of the sterilization. Explants planted then in MS medium for two weeks. Contamination time, percentage of contamination and viabilitas (percentage of living explants) were observed then. At the second phase, the treatments were arranged in a 3 x 3 factorial completely randomized design (CRD) to observed the influence of Kinetin and IAA combination. The concentration of Kinetin observed were 2, 4, and 6 mg/I, where as the IAA concentration were 0.5, 1.0, and 1.5 mg/I. All treatments were repeated three times, with three samples on each replication. The percentage of browning explants, percentage of contaminated explants, site of contamination and percentage of explants live were observed at the end of incubation. The results showed that sterilization of Durian young leaves explants with 1 g/l deterjent for 15 minutes then by 2 g/l Benlate and Agrept for 10 minutes, then by 1 g/200 mg Vitamin C, then by Alcohol 70 % for 1 minute, then by 20% Clorox, then by 2 drip of Tween-20 for 10 minute and then by Betadine decreased the contamination down to 50 %, and this kind of sterilization was relatively better than the other kinds. Application of growth regulators were not able to induce explants growth, but stimulated callus formation at the cutting surface though, in the application of Kinetin 4 mg/1 + IAA 0,5 mg/I, Kinetin 4 mg/1 + IAA 1,5 mg/1, Kinetin 6 mg/I+ IAA 0,5 mg/1 and Kinetin 6 mg/l+IAA 1,0 mg/I.
Sztuka w służbie imperium i narodu: casus bizantyjskich fresków w kaplicy Św. Trójcy na Zamku Lubelskim w świetle poglądów rosyjskich historyków (XIX –początek XX wieku)
Authors: Piccin Matteo 
Published: May 2021

Celem niniejszego artykułu jest refleksja nad nacjonalizmem rosyjskim – jego znaczeniem i zasięgiem terytorialnym, realnym, a także wyobrażonym – w Królestwie Polskim na przełomie XIX i XX w. Jako case study autor wybrał znamienite bizantyjskie freski z początku XV w., które pokrywają wewnętrzne ściany kaplicy Świętej Trójcy na Zamku Lubelskim w Lublinie. Autor stawia sobie pytanie, czy Lublin, ze względu na obecność fresków szkoły ruskiej, odsłoniętych dopiero na początku XX w., był w rozumieniu rosyjskich nacjonalistów miastem o rodowodzie ruskim (rosyjskim) i miał w takim razie ulec rusyfikacji, której sąsiednia Chełmszczyzna doświadczała od co najmniej 30 lat. Gdzie więc była granica nacjonalizmu rosyjskiego? Lublin leżał na granicy z ziemią chełmską, a odkrycie malowideł mogło spowodować zasadniczą rewizję spojrzenia na to miasto jako miasto polskie.
Znani intelektualiści polscy, a także rosyjscy archeologowie, historycy i badacze starożytności wzięli udział w debacie wokół pochodzenia fresków i ich genezy. I wojna światowa przerwała wszelkie projekty prac konserwatorskich, a wraz z nimi także próby dalszego odsłaniania „rosyjskości” Lublina.
