Abstract
Aims: Water quality is understood as the totality of its properties due to the nature and concentration of impurities in the water. Providing quality drinking water to citizens has become one of the most significant social problems and the most important factor of national security. The purpose of this study was to analyze the quality of drinking water in the city of Norilsk.
Materials & Methods: During the experiment, a team of researchers took samples of drinking water from the water supply network in various districts of the Norilsk industrial region (without preliminary draining and after 5 minutes of draining) and studied the dependence of the quality characteristics of water on the location and sampling method.
Findings: In terms of organoleptic indicators, drinking water in all Norilsk industrial region areas complies with the requirements of Sanitary Rules and Regulations and GOST. Sampling from three control points in the Norilsk industrial region showed that the water is soft, and its salt content is mainly due to hardness salts.
Conclusion: The presence of microorganisms in the water supply network of the Norilsk industrial region is not significant, and the permanganate oxidizability indicator does not exceed the requirements of Sanitary Rules and Regulations.

Abstract
Aims: This study aimed to analyse the snow cover in the Norilsk industrial region and assess the state of atmospheric air in the winter.
Materials & Methods: This experimental study was conducted in 2019. The organoleptic method was used for determining quality indicators based on the analysis of sensory perception; sight, smell, hearing, touch, taste.
Findings: Norilsk ranks second in terms of atmospheric contamination. Industrial enterprises annually emit large amounts of sulphur dioxide, phenols, and heavy metal particles. The city is located within the Far North and is distinguished by the harsh climate of the subarctic type. The snow cover can lie from 244 to 277 days. Snow is a good sorbent; therefore, the snow cover accumulates solid and gaseous pollutants that enter it from the atmosphere with precipitation or are absorbed from it.
Conclusion: Heavy metal ions and sulphate ions are not detected in the thawed snow, so no industrial gas pollution is noted in the residential area. Most of the particulate contamination is caused by slagging of roads to improve vehicle traction.

Abstract
Proper use of source material in second language writing is an essential skill in the academic writing process. The present study investigates source use and plagiarism level in the essay writing process by the English as a foreign language (EFL) student in one of the international universities in Tashkent, Uzbekistan. Thirteen first-year students who failed and then retook the language program were chosen for the purpose of the study. A mixed-methods research design was used to collect the data (i.e., language programs over two subsequent academic years were analyzed for their relevance to the process-based writing). To evaluate the students' opinions on both programs and correct academic citation, a paper-based questionnaire was circulated. The data analysis revealed a positive influence of program two on organizing ideas, incorporating source-text ideas, and using more academic and error-free sentences. A comparative analysis of the plagiarism level and writing performance in students' papers in both programs was performed using the Wilcoxon signed-rank test, which showed a positive difference in the overall writing scores but an insignificant difference in the level of plagiarism. Findings of the study identified that the engagement of the EFL undergraduate students in process-based writing made a positive impact on writing from sources and overall performance.

Abstract
Although email correspondence is a common means of communication between scholars from different cultures, little attention is paid to writing academic emails in tertiary education. The present investigation is aimed at studying the influence of genre education on the formation of academic writing skills and understanding the principles of academic correspondence. The main methods used in the study were experiment and survey. The research was carried out on the basis of National Research Nuclear University MEPhI. The participants of the study were postgraduate (PhD) students (n = 100) with a major in Physics, Electronics, Computer Science, and other technical areas. The results of the study show that the students made considerable progress in their academic email writing skills even after a short period of explicit instruction applying the genre-based approach. Most of the students changed their way of thinking about writing emails for academic purposes in English and became aware of the norms of formal writing. Moreover, the results of the experiment and survey justify the necessity of including academic email writing in the curriculum of teaching Academic English and demonstrate strong potential of genre-based learning in other genres involving academic writing.

Abstract
Layer by layer self - assembly technique is one of the newest methods to produce multilayer films relying on the placement of the liquid layers on solid substance. The purpose of this studies is to manufacture multilayer kraft based on protein biopolymers (zein and whey isolated protein) containing of green tea phenolic compounds by utilizing layer by layer self - assembly technique and evaluation antibacterial, physical-mechanical properties and release of phenolic compounds from coated kraft at refrigerator temperature in pH of 4.5 and 7. The minimum inhibitory concentration of green tea powder demonstrates that Escherichia coli (5mg/ml) compared to Listeria monocytogenes (10mg/ml) is more sensitive. The results of physical properties of krafts coated paper showed that thickness, grammage and bulk density increased by coating process. Also, the presence of zein in outer layer caused a significant reduction in WVP and increased air resistance. Evaluation of phenolic compounds release from coated krafts demonstrated that release rate in acidic food stimulant was more than the neutral stimulants. Also, release content of kraft paper with zein as outer layers respect to whey isolated protein was higher in the first days and continued in a longer time. Log reduction value of coated Kraft with active bilayer zein against Escherichia coli and Listeria monocytogenes was 0.25 and 0.06 respectively. According to the results of this study, active zein bilayer kraft is recommended as a carrier of phenolic compounds for the packaging of food products

Abstract
This study aimed at evaluating the reasons affecting organic food consumption of consumers in GAP-Şanlıurfa of Turkey. The sample size was determined using a 95% confidence interval and 382 questionnaire interviews were conducted. The participants were selected among the organic food consumers using a simple random sampling method. The Likert attitude scale, Mann-Whitney U and Kruskal-Wallis tests were used for analysis. It was observed that the existing knowledge and publicity about organic foods were insufficient; the main source of information was the internet. The consumers prefer to buy organic foods directly from the producers and there is a need for the organic bazaar. The fresh fruits and vegetables have a consumption frequency of 74.1%, followed by milk and milk products with 56%. The most important reason for consumption is being hormone-free, as shown by 93.7% of respondents, followed by odor-taste and flavor, with 92.7%. Color-appearance-packaging ranked last in terms of importance. The education level, followed by income, occupation, gender, marital status, age, settlement location and number of household members, are reasons that significantly explain the consumption behaviors. This study is one of the first of its kind in the GAP-Şanlıurfa. The results are important for agricultural producers and policymakers concerning agricultural production, marketing, and rural development.

Abstract
Chickpea (Cicer arietinum L.) is a traditional crop species in Turkey that is cultivated in almost every province providing prominent economic income. Turkey has an important resource for both Cicer spp diversity and their phytopathogens like ascohyta blight caused by Didymella rabiei (Kovachevski) von Arx wherein resistance/tolerance is broken every 4-5 years in cultivated chickpea cultivars. In order to breed resistant/tolerant varieties in chickpea against D. rabiei, detailed and up to date analyses on population characterization is needed. This study was undertaken to define current aggressiveness patterns, pathotype and mating type distribution of D. rabiei population in chickpea growing areas of Turkey. The D. rabiei isolates were assigned to 5 virulence groups in which existence of pathotype IV, a new and aggressive group, was defined for the first time from farmers’ fields and research institutes exhibiting continuous arm race between plant and pathogen. The isolates in each pathotype group depicted statistically important difference (P≤ 0.05) in virulence levels on chickpea genotypes. The mating type distribution of 971 D. rabiei isolates was 1:1 for Mat 1.1 and Mat 1.2 isolates (X2= 0.87, P= 0.35) exhibiting random sexual reproduction. Overall, the data obtained revealed the unstable aggressiveness nature of D. rabiei population in Turkey, which, in turn, explains frequent resistance overcome in registered chickpea genotypes leading to epidemics.

Abstract
The study was aimed at assessing the leg health variables (footpad dermatitis, hock burn, tibial dyschondroplasia, gait score), tarsometatarsus asymmetry, and physical properties of tibiatarsus of broilers reared with perch application and different litter thicknesses. A total of 459 one-day old Ross-308 broiler chicks were allocated into 27 pens, each containing 17 chicks, in a 3 (perch treatments)x 3 (litter treatments) experimental design with three replications. The position of both cooled and non-cooled perches was set to make animals pass over the perch for feeding and drinking. The perch temperature was set to 10°C for cooled perches while litter thicknesses were 1, 7, and 14 cm. Results showed that cooled perches decreased the severity of footpad and gait score, and tibial dyschondroplasia in broilers. Footpad dermatitis and hock burn score decreased in broilers reared at 14 cm litter. It was determined that the length and width of tarsometatarsus at 42 day of age was increased in cooled perch and 1 cm litter group. Tibia length and robustness index in cooled perch group was found higher than those in non-cooled and no-perch groups. The perch application has no effect on the weight-length and tibio-tarsal indexes. Tibia lengths in 1 cm (103.81 mm) litter thickness group were higher than in both 7 and 14 cm groups. The bones from 1 cm litter thickness group were found heavier (21.55 g) than in 7 cm litter group. These results indicated that cooled perch and 14 cm litter thickness has a beneficial effect on broilers’ well-being in hot weathers.
