Authors: Халадов А.Ш. 
Published: February 2022

Эффективность эксплуатации глубоких скважин в значительной степени снижается в результате обводнения добываемой продукции, что приводит к существенному уменьшению добычи нефти, вызывает необходимость в дополнительных затратах, связанных со сбором, транспортом и подготовкой нефти, защитой нефтепромыслового оборудования от коррозии, что, в целом, ухудшает технико-экономические показатели разработки нефтяных залежей.Для ограничения водопритоков в пределах существующего интервала перфорации (без перехода вверх) разработаны и применяются в отечественной и зарубежной нефтепромысловой практике различные технологические процессы с использованием в качестве изолирующих составов разного рода суспензий, эмульсий, коллоидных и химических растворов, пенных систем, загущенных жидкостей, поверхностно-активных веществ.
The efficiency of operation of deep wells is significantly reduced as a result of water cut in the produced products, which leads to a significant decrease in oil production, necessitates additional costs associated with the collection, transportation and treatment of oil, protection of oil field equipment from corrosion, which, in general, worsens the technical-economic indicators of the development of oil depositTo limit water inflows within the existing perforation interval (without going up), various technological processes have been developed and are used in domestic and foreign oilfield practice using various kinds of suspensions, emulsions, colloidal and chemical solutions, foam systems, thickened liquids, surface active substances.

Published: February 2022

A bacia hidrográfica do rio Apodi-Mossoró, inserida na mesorregião oeste do estado do Rio Grande do Norte, ocupa uma área de 14.276 km² e seu desenvolvimento econômico é baseado na exploração de recursos naturais. Desse modo, é uma importante unidade de planejamento ambiental, a qual exige informações sobre características morfométricas, sua aptidão de uso e cobertura da terra, para identificar a intensidade da deterioração do sistema ambiental. Nessa identificação foram utilizados dados da drenagem, focos de incêndios, modelo digital de elevação e imagens de satélite do Landsat 8 - OLI. Os parâmetros morfométricos utilizados foram: fator de forma (Ff), índice de circularidade (Ic), coeficiente de compacidade (Kc), densidade de drenagem (Dd), declividade média (Dm) e coeficiente de rugosidade (RN). Com a aplicação do diagnóstico físico conservacionista foi possível quantificar e analisar o grau de deterioração da área estudada que foi de 27,77% e apesar de ser considerado alto, as sub-bacias 1 e 2 apresentaram um elevado grau de deterioração com 90% e 83% respectivamente. Isso mostra a importância do estudo e possibilita uma visão detalhada das áreas prioritárias. Por conseguinte, a aplicação de técnicas de geoprocessamento configura-se uma etapa fundamental na gestão de sistemas ambientais.Palavras-chave: Sistema Ambiental. Aptidão Agrícola. Deterioração.

An Aging Cyclists Time Trial Performances over Four Decades: A Case Study
Authors: Dyer Bryce 
Published: February 2022

Previous research has often highlighted the physiological decline an athlete will be subjected to as they age. However, whilst some studies has evaluated a large sample of athletes at a given age, few studies have evaluated a single athlete over a much longer period of time in sports such as cycling. This study assessed the time trial performances of a multiple national record holding male amateur cyclist from when they were aged between 37 to 75 years of age. 488 of their individual performances over nearly four decades were contrasted against a statistically generated baseline of athletes that they competed against during these events. The results indicated a relatively stable level of performance from aged 37-52 years of age. However, a noticeable decline began to take place at aged 61 which then degraded sharply at aged 70. Interestingly, the athlete did not exhibit a permanent reduction in their average velocity in their best 16.1km and 40.2km time trial performances until aged 70. This suggests that despite the physiological decline that will eventually reduce a riders competitiveness, this case study demonstrated that it is feasible to continue the pursuit of personal records until relatively late in life.
The use of the Lamberts Submaximal Cycle Test in Triathlon, an exploratory study in young professional sprint triathletes
Authors: Lamberts Rob 
Published: February 2022

Abstract: The Lamberts Submaximal Cycle Test (LSCT) has proven itself as an effective tool to monitor and fine-tune training prescriptions for trained to elite cyclists whilst also being able to reflect identifying early symptoms of fatigue and/or overreaching. Although considered a popular monitoring tool in cycling, it is not clear how well the design of the LSCT relates triathlon performance. Therefore, the aim of this initial study was to determine whether a relationship exists between the LSCT and actual sprint triathlon performance in six young professional triathletes. As part of the study all triathletes performed the LSCT 2 days before the Dutch National Championships, while the relationships with overall and split sprint triathlon times were studied. All triathletes successfully finished the National Championships, with 3 winning their age and gender category. A good Spearman’s rho correlation (rs) between between the power output during LSCT stages 2 and 3 and overall sprint triathlon finishing time (rs = -0.94, p = 0.017). As expected, based on the cycling nature of the LSCT, the strongest correlations with split triathlon time, were found between LSCT stages 2 and 3 power output and split cycling time (rs = -1.0, p <0.001 and rs = -0.99, p = 0.006, respectively). Slightly weaker relationships were correlations were found with split running time (rs = -0.94, p = 0.016) and swimming time (rs = -0.94, p = 0.017), while no relationships were found with heart rate recovery. Findings yielded by the initial study suggest that the LSCT relates well to both the overall as well as split triathlon performances of professional athletes. Although a larger sample study is needed to confirm and determine the accuracy of the LSCT in a more heterogenous group of triathletes, the findings of this initially study highlight the potential of the LSCT as useful monitoring tool for triathletes.

Background. Anthracnose black rot caused by the phytopathogenic fungus Colletotrichum acutatum Simmonds became an extremely harmful disease of strawberries in Southern Russia. The disease is widespread throughout the world, and relatively recently it appeared in Russia. Yield losses due to the disease reach up to 80%; besides, the pathogen causes significant plant losses in mother plantations. The most reliable protection against the pathogen is the cultivation of resistant varieties. In strawberries, resistance is controlled by different genes, including Rca2. To identify this gene, molecular markers STS_Rca2_240 and STS-Rca2_417 have been developed. The purpose of this study was to use the markers for screening the VIR collection of strawberry varieties at the VIR Maikop Experiment Station (Maikop ES VIR). Material and methods. The present work studied 135 varieties of Fragaria × ananassa (Duchesne ex Weston) Duchesne ex Rozier, 83 domestic and 52 foreign ones. The domestic varieties included 17 created at the Maikop ES. Plants were evaluated for anthracnose field resistance in the Republic of Adygea from 2018 to 2021. Molecular screening was performed using STS_Rca2_240 and STS-Rca2_417, the molecular markers closely linked to the Rca2 gene. Microsatellite primers EMFv020 were used to control the PCR. The cultivar ‘Sudarushka’, in which the presence of STS_Rca2_240 marker was described in the literature, served as a positive control. Results and discussion. The marker Rca2_240 was detected in 22 cultivars from 135 studied. Among domestic varieties, the frequency of the marker was 18.1%, while among the foreign varieties it was slightly lower and amounted to 13.0%. Among the 17 varieties created at the Maykop SE, the marker was found in three: ‘Majkopskaya rannyaya’, ‘Peryt’, and ‘Shapsugskaya’. The association of the diagnostic fragment with resistance was 73.0%. The marker efficiency was not very high due to the significant number of resistant varieties which do not generate the diagnostic fragments. The resistance in such varieties can be provided by other genes, for example, FaRCa1. The STS-Rca2_417 marker was not effective during screening. Conclusion. Twenty-two varieties with the STS_Rca2_240 marker were identified in the VIR collection, maintained at the Maykop ES VIR, 16 of which were resistant to C. acutatum. These varieties represent a valuable breeding material. The STS-Rca2_240 marker can be used as an important diagnostic trait for the certification of varieties.
Effects of Male International Migration on Mental Health of Wives Left Behind in Nepal
Authors: Bhirtyal Yagya Murti , Wasti Sharada Prasad 
Published: February 2022

Introduction: International male migration is very common and has been increasing significantly in recent days in Nepal.The increasing pattern of male migration has greatly impacted left-behind women. The aim of the study was to assess the effects of male international migration on the mental health (depression) of wives left behind in Nepal.
Methods: A cross-sectional study was conducted with a total of 800 women (400 wives left behind and 400 wives of non-migrants) in the Chitwan district of Nepal.A systematic random sampling approach was employed for the recruitment of study respondents.Data were collected through a structured questionnaire with face-to-face interviews.Depression was measured by using a valid tool of depression screening questionnaire consisting of a 20-items scale. Data were managed in SPSS version 19 and analysed with a descriptive statistic followed bylogistic regression analysis. Ethical approval was obtained from the Nepal Health Research Council and individual written consent was obtained prior to the interview.
Findings: The prevalence of depression in left-behind wives was 79 percent whereas only a 26.3 percent prevalence rate was found in the wives of non-migrants. There was a significant difference in depression between left-behind wives and the wives of non-migrants. The left-behind wives (OR = 10.57, p < 0.001) had around 11 times greater odds of having depressive symptoms compared to the wives of non-migrants. Logistic regression shows that theCaste/ethnicity (OR 1.15), level of education (OR 2.4), own named property (OR 1.7), and having children (OR 8.39) were identified as factors influencing depression in left-behind wives. However, the age of the wives (OR 0.46), level of education (OR 1.77), and employment status (OR 1.7) were found as factors that influence the depression in the wives of non-migrants. Findings between the left-behind wives and the wives of non-migrants depict that only women’s education (OR 2.94 vs 1.77) was found to be significantly associated with depression in both groups.
Conclusions: The increasing trend of male international migration has negative effects on left-behind wives regarding health and wellbeing. There should have targeted intervention mental health screening and counselling programs forboth non-migrant and left-behind wives for early detection and treatment. Government should plan psychosocial counselling clinics and awareness-raising programmes particularlyto the higher male migration communities for early detection and treatment.
