The efficiency of deep air cooling at the inlet of gas turbine units has been investigated for changed climatic conditions of operation during the month. For air cooling, the use of waste heat recovery chiller has been considered, which transform the heat of exhaust gases of gas turbine units into the cold. The efficiency of air cooling at the inlet of gas turbine units to different temperatures has been analysed: to 15°C – an absorption lithium-bromide chiller, which is used as the first pre-cooling stage of ambient air and down to 10°C – a combined absorption-ejector chiller, with ejector refrigerant chiller as the second stage of air cooling.The air cooling efficiency is estimated for different climatic conditions: a temperate climate on the example of Odessa (Ukraine) and a subtropical climate for Guangzhou (China). The subtropical climate peculiarity of Guangzhou is the high relative humidity of the air, respectively, and its moisture contents at the same time its high temperatures. As an indicator, when evaluating the efficiency of air cooling at the inlet of gas turbine units to 15°C in an absorption lithium-bromide chiller and deep cooling of air to 10°C in a combined absorption-ejector chiller, the specific fuel consumption reduced has been used. In this case, the needs for specific production of refrigeration capacity and specific capacity of cooling towers for cooling waste heat recovery chillers when cooling air to different temperatures are compared. It is shown that, through extremely different thermal and humidity parameters of ambient air, its cooling at the inlet of gas turbine units to 10ºС for the climatic conditions of Ukraine provides the current decrease in specific fuel consumption due to deeper cooling of the air at the inlet of the GTU in 1.6 ... 1.7 times compared with cooling to 15ºС, and for climatic conditions of the PRC - 1.4 ... 1.45 times. However, it should be noted that a deeper cooling of the air at the inlet of the gas turbine unit to a temperature of 10°C in a combined absorption-ejector chiller compared to its traditional cooling to 15°C in an absorption bromine-lithium chiller requires an increase in the required specific amount of cold by 1.7 ... 2, 0 times and the required specific capacity of cooling towers for cooling chillers by 2.6 ... 3.0 times for the climatic conditions of Ukraine, while for China - 1.25 ... 1.3 and 1.5 ... 1.6 times, respectively.

Published: March 2020

An important element in ensuring the epizootic well-being of the poultry industry is disinfection. Modern poultry farming requires a large number of effective disinfectants. It is known that the resistance of microorganisms to the effects of disinfectants is based on a genotypic mechanism. The nature of the formation of resistance to disinfectants and antiseptics is different than antibiotics. With regard to disinfectants, resistance is formed more slowly and the proportion of resistant strains in the population of microorganisms may not be high for a long time. This is due to different mechanisms of formation of resistance to antibiotics and disinfectants, in the first case – plasmid mechanism, in the second – chromosomal. However, increasing the resistance to the active substance in disinfectants can be widespread, so it is necessary to periodically rotate disinfectants. The goal of the work – to investigate the parameters of acute toxicity of the disinfectant biocide “Zodizin”. The studies were conducted in the laboratory of Veterinary Pharmacy and the Vivarium of Sumy National Agrarian University. The drug “Zodizine” contains: polyhexamethyleneguanidine hydrochloride – 21.0 %, alkylldimethylbenzylammonium chloride – 3.0 %. For toxicological examination of the disinfectant, healthy white male rats and white female rats weighing 200 ± 10 g 1.5 years of age were used. In the study of acute toxicity of animals observed daily, noted the general condition of the animals, features of their behavior. Studies have found that the toxic effect of the disinfectant “Zodizin” clinically manifested almost equally in both males and females. The average lethal dose for the rat female was 1000.0 ± 35.0 mg/kg body weight, males 1033.0 ± 34.3 mg/kg. Therefore, according to the classification of substances by toxicity, the drug by intragastric administration can be attributed to low-toxic substances. Observations on animals revealed that 1–3 hours after oral administration of the drug in a subtoxic dose in laboratory animals, shortness of breath and inhibition of the central nervous system were noted. Most of them died during the first day. Subsequent observations of the surviving animals indicated that their motor response was suppressed over the next 24–72 hours. Conclusions and prospects for further research: 1. It was found that the average lethal dose of the drug “Zodizin” with oral administration to rats-females was 1000.0 ± 35.0 mg/kg body weight, males – 1033.0 ± 34.3 mg/kg. 2. Experimental studies have proved that the disinfectant “Zodizin” according to GOST 12.1.007-76, belongs to the IV class of danger, that is, to the low-dangerous compounds, and according to GOST 12.1.07 – to the III class of hazard of substances and can be used for disinfection premises where animals and poultry are kept. Further, the sporoсide and corrosion properties of the “Zoodizin” biocide will be studied.

Beyond Imperialism: The 19th-Century Display of Chinese Art at the Musée Guimet
Authors: Heng Wong Yuet 
Published: March 2020

La fin du XIXe siècle fut le témoin d’une interaction culturelle entre la Chine et la France d’une intensité sans précédent, mais non dénuée d’ambiguïté. Des collections d’art chinois considérables se constituent alors, dont celle du musée Guimet. Aujourd’hui, nombre d’expertises sur l’acquisition des œuvres d’art à cette époque se structurent au sein de la théorie post-colonialiste, où le contexte impérialiste forme le cadre de l’interprétation occidentale de l’ « Est ». L’auteur analyse ici l’éventualité d’une mise en scène de la supériorité occidentale dans la présentation d’objets chinois dans les salles du musée Guimet. L’examen des catalogues publiés alors et des écrits d’Émile Guimet nourrit l’étude des éléments ayant contribué à cette présentation, telles que la localisation géographique, l’architecture, la division des espaces, la classification des objets, la succession des salles ou la décoration intérieure. L’on montre comment Guimet a transformé l’approche exotique de l’art chinois en une présentation scientifique visant à mettre l’accent sur la richesse de la culture chinoise, et comment la supériorité française dans la création d’un savoir sur l’Est fut contrebalancée par la mise en évidence des échanges, passés et contemporains, entre la Chine et la France.

Abstract
Advanced contactless photoelectrochemical etching for GaN was conducted under the condition that the sulfate radicals (SO4
·−) as the oxidizing agent were mainly produced from the S2O8
2− ions by heat. The generation rate of SO4
·− was determined from the titration curve of the pH in the mixed solutions between KOH (aq.) and K2S2O8 (aq.); it clearly increased with an increase in the S2O8
2− ion concentration. The highest etching rate of >25 nm min−1 was obtained in the “alkali-free” electrolyte of 0.25 mol dm−3 (NH4)2S2O8 (aq.) at 80 °C, which was approximately 10 times higher than that reported by previous studies.
The Microbiota Continuum along the Reproductive Tract in Women with Infertility
Authors: Godovalov A. P. , Karpunina T. I. 
Published: March 2020

Introduction. At present, the question of commensal, including opportunistic, microflora participation in infertility development remains debatable. In a number of studies, the translocation of the vaginal microflora into the endometrial tissue is considered as a factor contributing to inflammation development. In addition, the connection of some reproductive losses with the persistence of certain conditionally pathogenic microorganisms is shown. Today, to solve this issue, molecular genetic research methods are being actively introduced that surpass the routine cultivation techniques in a number of positions.The aim of the study was to assess the taxonomic diversity of microorganisms in the vaginal biotope with infertility.Material and methods. For the study samples of vaginal contents obtained from the posterior vaginal fornix of 15 women, consisting of barren marriage, were used. A metagenomic study of 16S ribosomal RNA samples was carried out on the Illumina MiSeq platform, using the MiSeq Reagent Kits v3 kit (600-Cycle Kit), as recommended by the manufacturer. Libraries for sequencing plots of the V3-V4 gene of the 16S ribosomal RNA were prepared according to the 16S Metagenomic Sequencing Library Preparation Illumina. In bioinformatics assessment, Kraken Metagenomics version 2.0.0 software for metagenomic analysis (classifier of reads — short nucleotide sequences) was used using a standard database.Results. It was shown that the occurrence of representatives of the Lactobacillaceae family in the vaginal biotope varies from 12 to 84%. The genus Lactobacillus with the dominance of L. jensenii, L. delbrueckii and L. amylolyticus occupied the leading position among the members of the family. In all samples, Moraxella spp. was found in large numbers, with M. osloensis leading among the representatives of the entire community. In half of the cases, the joint presence of M. osloensis and G. vaginalis was revealed.Conclusion. It has been established that in infertility in the vaginal microbiota the number of representatives of the genus Lactobacillus is significantly reduced, and there is also a change in the leading species to L. jensenii, whose functional activity does not fully ensure the colonization resistance of the vaginal biotope, allowing for excessive reproduction of oppotrunistic microorganisms, in particular, M. osloensis.

Background. Psychiatric hospitals, where patients with immunodeficiency often do not comply with basic preventive measures, as well as receiving a wide range of medical procedures, including parenteral ones, are the institutions of high risk of socially significant infections spreading.The aim was to study the current epidemiological features of parenteral hepatitis among various categories of mentally ill patients (with pulmonary tuberculosis and HIV infection) and medical personnel in a large psychiatric hospital.Materials and methods. Serological markers of hepatitis B (HB) and hepatitis C (HC) were determined in 8352 patients and 542 employees of a large psychiatric hospital using domestic diagnostic test systems.Results. Markers of HB and HC among patients were revealed in 7.2% of persons (HB — 2.8%, HC — 3.1%, and HB+HC — 1.4%). The analysis of sex, age and social characteristics of HBVand HCV-patients was conducted. Markers of HC were significantly more common in HIV-infected patients (44.4% of individuals); the main routes of transmission of HB and HC were intravenous drug use and sexual intercourse. Among patients with pulmonary tuberculosis, the maximum number of persons was found with markers of HB (44.3%) and HB+HC (38.2%); the main clinical form of pulmonary tuberculosis was represented by the infiltrative form (60.4%); in 53,7% of cases the bacillary forms were identified that pose a serious epidemiological risk in the spread of tuberculosis in the hospital. Analysis of the social structure showed that HBV+HC+HIV and pulmonary tuberculosis are characteristics of persons with aggravated social status. The most frequent factors of infection with HBV and HCV were longterm parenteral loading and intravenous drug use. The greatest factor of parenteral load was observed in mentally ill patients diagnosed with HB+HC accompanying tuberculosis. It was shown that the frequency of HBV and HCV markers detection among medical personnel depends on the department profile, work duration, frequency and risk of contact with blood during professional activity.Conclusion. A high level of comorbidity of mental disorders and socially significant infectious diseases (HIV infection, tuberculosis and HB and HC) has been established, which has a significant impact on the epidemic process of these infections. Preventive programmes established in hospitals and in the territories they serve should take into account their comorbidity. The necessity of specific and non-specific prevention of viral hepatitis in patients and medical staff of psychiatric hospitals is shown.

Bullying: tres miradas de una misma realidad. Un estudio exploratorio en la escuela primaria
Authors: Krumm de Nikolaus Sonia , Nikolaus Raúl 
Published: March 2020

El bullying es un fenómeno relacional en el que intervienen numerosas variables personales, institucionales y sociales. En este último ámbito, la investigación demuestra que la violencia estructural de los sistemas, el contagio social de las conductas y los valores provenientes de las creencias en la cultura predominante tienen un alto impacto en los niveles de intimidación que pueden darse en la escuela. Sin embargo, no todos los actores de la educación perciben el fenómeno de la misma manera, dado que el bullying es un comportamiento oculto y aparece bajo la mirada cómplice de quienes rodean a la víctima y al victimario. ¿Cuál es el grado de conciencia acerca de la existencia del bullying en la escuela y qué nivel de compromiso hay en la prevención de su aparición por parte de cada uno de los actores de la educación?
El tipo de estudio corresponde a un diseño de corte transversal y descriptivo y a una metodología cuanti-cualitativa, cuyos resultados están basados en la triangulación del instrumento PRECONCIMEI, compuesto de tres encuestas autoadministradas, una para alumnos, otra para docentes y una tercera para padres. El propósito de este trabajo fue explorar y contrastar el nivel de bullying percibido por los niños de 4º, 5º y 6º años de educación primaria, con el nivel de bullying percibido por docentes y padres en ambientes suburbanos. El objeto último de este estudio consistió en crear conciencia acerca de la existencia de intimidación entre escolares que impulse a proponer planes de prevención y tratamiento, involucrando a todos los actores de la comunidad educativa.
