Main problem: Microbial-plant relationships, including epiphytic microflora, are the subject of attention of many scientists. Numerous works confirm the high interest of researchers and the relevance of studying this topic. Despite many years of research, some questions concerning the characteristics of the epiphytic microflora still remain open. It is already a well-known fact that the epiphytic microflora is directly related to the physiological development of the plant, including yield. This is due to the close interaction of the plant with the microorganisms living on its surface throughout the entire growing season. It is also proved that epiphytic microflora has the ability to change characteristics under the influence of environmental factors (temperature, humidity, soil contamination, sunlight, etc.). In this regard, the study of this topic is one of the important areas of biological and agricultural sciences and is of high importance. It should be noted that a significant role in the development of agriculture in the Republic of Kazakhstan and the Pavlodar region is played by representatives of vegetable crops, including tomatoes and potatoes belonging to the Solanaceae family, which indicates the high importance of the plants selected for the study. The combination of the above arguments determines the need to study the epiphytic microflora of plants and establish the regularities of its influence on the adaptive properties of the studied plants of the Solanaceae family, as well as on their productivity. In turn, the study of epiphytic microflora can also contribute to the search for new ways to increase the yield of plants and their resistance to various diseases. Purpose: The article is devoted to the study of the properties and characteristics of the epiphytic microflora of the surface of various organs of plants of the Solanaceae family (on the example of tomato and potato). The variability of the composition and number of epiphytic microorganisms in seasonal dynamics is shown. Methods: bacterioscopic method, fingerprint method, flushing method, Gram staining method. Results and their significance: The characteristics and properties of representatives of epiphytic microorganisms of aboveground (leaf, fruit, flower) and underground (potato fruit) plant organs were studied. The role of the influence of environmental factors on the variability of epiphytic microflora is determined on the example of plants Lycopersicon esculentum Mill. (common tomato) and Solanum tuberosum L. (tuberous nightshade). The differences in the microflora of different plant organs in different periods of vegetation are shown.

AbstractCorona virus disease 2019 (COVID-19) has been declared a global pandemic and is a major public health concern worldwide. In this study, we aimed to determine the role of environmental factors, such as climate and air pollutants, in the transmission of COVID-19 in the Republic of Korea. We collected epidemiological and environmental data from two regions of the Republic of Korea, namely Seoul metropolitan region (SMR) and Daegu-Gyeongbuk region (DGR) from February 2020 to July 2020. The data was then analyzed to identify correlations between each environmental factor with confirmed daily COVID-19 cases. Among the various environmental parameters, the duration of sunshine and ozone level were found to positively correlate with COVID-19 cases in both regions. However, the association of temperature variables with COVID-19 transmission revealed contradictory results when comparing the data from SMR and DGR. Moreover, statistical bias may have arisen due to an extensive epidemiological investigation and altered socio-behaviors that occurred in response to a COVID-19 outbreak. Nevertheless, our results suggest that various environmental factors may play a role in COVID-19 transmission.

The paper presents the results of evaluating the efficiency of feed rations offered to broilers of the Arbor Acres cross, formed taking into account the climatic, geochemical conditions of Central Africa and its native food flora. The study was conducted on the basis of an experimental farm at the University of N’Djamena, the Republic of Chad. In the experiment, the authors used five formulas of feed rations, which are currently used by farms in the Republic of Chad for growing broiler chickens. They mainly contain locally availble ingredients. To increase the resistance of the poultry organism to unfavorable environmental factors, the chickens of the control and experimental groups were given “TETRACOLIVIT” and “AMIN’TOTAL” vitamins. The efficiency of feed rations was evaluated by determining the age dynamics of live weight, average weekly gains in live weight and blood biochemical parameters of broiler chickens of the Arbor Acres cross from 1 to 42 days of life. The formula of feed ration No. 1 proved to be the most effective in terms of the cross productivity.

Rail foot flaws have the potential to cause broken rails that can lead to derailment. This is not only an extremely costly issue for a rail operator in terms of damage to rolling stock, but has significant flow-on effects for network downtime and a safe working environment. In Australia, heavy haul operators run up to 42.5 t axle loads with trains in excess of 200 wagons and these long trains produce very large cyclic rail stresses. The early detection of foot flaws before a broken rail occurs is of high importance and there are currently no proven techniques for detecting rail foot flaws on trains at normal running speeds. This paper shall focus on the potential use of thermography as a detection technique and begin investigating the components of heat transfer in the rail to determine the viability of thermography for detecting rail foot flaws. The paper commences with an introduction to the sources of heat generation in the rail and modelling approaches for the effects of bending, natural environmental factors and transverse defects. It concludes with two theoretical case studies on heat generated due to these sources and discusses how they may inform the development of a practical thermography detection methodology.

Multiple sclerosis (MS) is a common autoimmune disease, which etiology includes a complex of genetic and environmental factors. Data suggests that their interaction can influence the age of the clinical manifestations and the course of the disease. Therefore, the study of risk factors of MS in regions with different ethnic compositions of the population and climatic and geographical characteristics is of considerable interest.Objective: to study MS risk factors prevalence in the Republic of Kabardino-Balkaria (RKB).Patients and methods. This case-control study of the representation of risk factors included a cohort of 112 MS patients living in two regions of the RKB (Nalchik and the Prokhladnensky district). The MS diagnosis was established with the McDonald criteria (2017). MS risk factors were assessed with a unified questionnaire. 112 respondents (matched by the main demographic characteristics and place of residence) were included in the control group.Results and discussion. MS patients from the Prokhladnensky district were significantly more likely to contact harmful chemical compounds, had higher consumption of smoked meat products; and suffered from viral infections more often (all differences were significant, p<0.05). More patients with MS, regardless of their place of residence, had a history of scarlet fever than the controls (n=23; 19.5% and n=14; 13.4%, ratio indicator 0.43 (95% CI 0.32–1.01), p=0.041), and the maximum significance of this factor was found in patients who suffered from scarlet fever after the age of 15 years (n=7; 6.3% and n=1; 0.9%, ratio indicator 2.45 (95% CI 1.92–3.21), p=0.041). More patients with MS had a history of chickenpox (n=70; 62.5% and n=55; 41.1%; ratio indicator 0.78 (95% CI 0.65–0.94, p=0.032), the frequency of this factor was most significant in early (up to 7 years) disease onset. Regardless of the place of residence, patients with MS were more likely to suffer from tonsillitis and sinusitis in childhood (p=0.032).Conclusion. In the RKB, as in other regions of the Russian Federation, the risk of MS, along with a genetic predisposition, is primarily determined by environmental factors, such as contact with potentially harmful chemicals, history of somatic diseases, characteristics of the ecological situation, etc. Therefore, MS risk is higher in people exposed to these factors before the age of 7 years and does not depend on the place of residence.

The Impact

The impact of globalization has penetrated throughout the civilization of the nations of the world, running so fast. Especially very influential on changes in various lines of life. Related to this is the issue of increasing narcotics abuse and narcotics illicit trafficking which has created conditions that have hindered the development process and weakened civilization. Eradication of narcotics distribution is a national problem, because it has a negative impact that can damage and threaten the lives of the people, nation and state and can hamper the national development process. The rise of narcotics abuse does not only occur in big cities, but has reached small cities in all ten regions of the Republic of Indonesia, including East Aceh Regency. The increasingly diverse lifestyle of the people due to the influence of globalization also contributes to the increasing circulation of narcotics in East Aceh District. This certainly must receive serious attention, because if we look at what is happening in East Aceh District and several other regions in Indonesia, the crime of narcotics distribution from time to time always increases which in the end is increasingly unsettling the community, so before these things increase In East Aceh District, an effective solution must be found to eradicate it. Factors that cause a person to commit a narcotics crime in East Aceh Regency are due to economic factors where a person needs money to live and the difficulty of getting work, family environmental factors, social environmental factors and availability / lack of supervision factors. Efforts in tackling narcotics circulation in East Aceh district involve many parties, including: firstly, pre-emptive efforts by providing counseling in the community and schools about narcotics carried out by the police in tackling narcotics crime in East Aceh District. Second, preventive measures (prevention) by conducting raids and patrols routinely, providing oversight of the association and positive activities carried out by the police, prosecutors, religious leaders, community leaders and youth organizations. The third repressive effort (action) which aims to provide a deterrent effect on the perpetrators of drug trafficking crimes involving all law enforcement officials ranging from the Police, Attorney and District Courts and Detention Houses.Keywords: Crimonology, Narcotics Circulation.

Globally, an increase in the transportation and expansion of the pet market is the most important cause of the invasion of non-native species. Invasion of non-native species disturbs native ecosystems and leads to socio-economic problems. The pet trade involving turtles has been globally recognized as the route through which non-native species enter ecosystems. As a result, the invasion of non-native turtles worldwide is causing problems such as competition, predation, transmission of parasites, and hybridization with native turtles. Every year, both the number of non-native turtles imported as pets in the Republic of Korea and the number of introduced species found in the wild is increasing. However, the current status of non-native turtles in the wild is not well known, posing major challenges to their management. In this study, we aimed to determine the current status of non-native turtles introduced into the wild in Korea. We analyzed the factors associated with the detection and distribution of non-native turtles. In total, 1587 of non-native turtles (three families, six genera, and 13 species including subspecies) were found in 648 sites in Korea: Chelydra serpentina, Mauremys sinensis, Chrysemys picta bellii, Graptemys ouachitensis, G. pseudogeographica pseudogeographica, G. p. kohni, Pseudemys concinna, P. nelsoni, P. peninsularis, P. rubriventris, Trachemys scripta elegans, T. s. scripta, and T. s. troostii. There was relationship between the distribution of non-native turtles and environmental factors such as precipitation and temperature. Moreover, human factors such as number of human populations and size of region were significantly related with the distribution and number of non-native turtles. In conclusion, it is likely that human factors are associated with the influx of invasive turtles to the natural habitat, while the possibility of survival and adaption for the turtles is associated mainly with environmental factors. Our result will be an essential guideline not only for understanding the current status of non-native turtles in Korea, but also for establishing strategies for management and control.
