Authors: Assabri A. M. , Muharram A. A.
Published: September 2021

In the Republic of Yemen, Plasmodium falciparum is the predominant causative agent of malaria and is associated with adverse consequences for pregnant women and their babies. The prevalence and clinical manifestations of malaria among 500 pregnant [260] and non-pregnant [240] women were compared. Clinical examinations, laboratory investigations and a structured questionnaire were used to collect data. The prevalence of malaria was higher among pregnant women [55%] than non-pregnant women [20%]. Anaemia was significantly more prevalent among pregnant woman than non-pregnant women and also more prevalent in pregnant women with malaria than non-pregnant women with malaria.

Authors: Yaqubi G., H. , Anani G. R.
Published: September 2021

Between January 1999 and December 2000, 80 consecutive patients with chronic conjunctivitis presenting in the eye clinic of Birjand University of Medical Sciences were assessed for trachoma and chlamydial infection. Direct fluorescent antibody test was used to assess trachoma and Giemsa staining to detect chlamydial infection. Trachoma was detected in 10% of the patients and chlamydial infection detected in 6.3%. The results were similar for both sexes. Although the findings are hospital-based, the prevalence was not so high as to suggest prophylactic use of azithromycin [World Health Organization protocol] for eradication of trachoma in the Birjand population. Further epidemiological studies are recommended.

Authors: Gunaid A. A.
Published: September 2021

The present study was undertaken to determine the prevalence of known cases of diabetes and hypertension among adults in Sana’a city. Thus 1080 persons aged 20-85 years were selected for interview using a multistage random sampling technique. The crude prevalence of known diabetes was 6.57% [95% CI: 5.2-8.2] and of known hypertension 13.5% [95% CI: 11.5-15.6]. The age-standardized prevalence for the age range 30-64 years was 9.75% [95% CI: 7.55-11.95] for diabetes and 17.1% [95% CI: 15.0-19.2] for hypertension. These results provide an estimate of the prevalence of known diabetes, hypertension and related vascular events in a well-defined urban community.

Authors: Garib B. T. , Al Ani S. , Al Alwan N. , Tillawi I. S.
Published: September 2021

We studied the DNA content, DNA index and cell cycle parameters that are reliable markers for assessing the proliferative activity and aggressiveness of malignancies. Cytometric DNA analysis was performed on formalin-fixed paraffin embedded sections from 36 Iraqi patients with oral squamous cell carcinoma. The results showed that 20 of 36 cases [55.5%] were diploid, while 15 cases [41.7%] were aneuploid. Significantly higher S-phase fractions and higher DNA indices characterized aneuploid tumours. Nuclear DNA analysis as part of the evaluation of oral squamous cell carcinoma will influence the selection of appropriate treatment strategies.
Antioxidant micronutrients in children with thalassaemia in Egypt
Authors: Nasr M. R.
Published: September 2021

Repeated blood transfusions in patients with thalassaemia subject them to peroxidative tissue injury by secondary iron overload. To study the relationship between iron overload and antioxidant micronutrient status among children with thalassaemia, we measured serum levels of vitamins A and E, zinc, selenium, and copper in 64 children with beta-thalassaemia major and 63 age- and sex-matched controls. All of these elements were significantly lower in the thalassaemic children compared with controls. There was a highly significant inverse correlation between serum ferritin and serum retinol levels, and significant inverse correlations between serum iron and retinol and between serum iron and selenium. Serum ferritin showed a significant positive correlation with duration of chelation and transfusion treatments. Ways are needed to counteract this oxidative damage and its deleterious effect on the prognosis of thalassaemia.
Vaginal misoprostol in managing premature rupture of membranes
Authors: Ayad I. A. A.
Published: September 2021

We compared the efficacy of misoprostol with that of prostaglandin E2 in cervical ripening and labour induction. Thus 238 women with rupture of membranes beyond 36 weeks gestation without labour were randomized to receive 50 microg misoprostol vaginal gel or 5 mg of prostaglandin E2 gel. Bishop score was evaluated before drug application and 6 hours later. Clinical data and perinatal outcome were recorded. Mean time from induction to delivery and the need for oxytocin were significantly less in the misoprostol group. There were no significant differences in spontaneous labour rate, type of delivery and perinatal outcome. It is concluded that intravaginal misoprostol is safe and more effective than prostaglandin E2 for preinduction cervical ripening in premature rupture of membranes beyond 36 weeks gestation.

Authors: Nakhaee F. H.
Published: September 2021

Knowledge of prisoners regarding HIV/AIDS in Kerman was evaluated. Analysis indicated that the sample [n = 350] of prisoners had relatively high knowledge about HIV/AIDS and its modes of transmission. However, they had a lower level of knowledge about HIV/AIDS prevention. The overall knowledge of men about AIDS was significantly lower than women. Persons aged 46 years and older and illiterate inmates had the least knowledge about modes of transmission. In addition, the knowledge of illiterate prisoners about HIV/AIDS prevention was significantly lower than others. Evaluation of attitudes and practices of prisoners and implementation of educational programmes regarding HIV/AIDS are suggested.

Authors: Awad K. Z.
Published: September 2021

The relationship of AIDS knowledge and self-efficacy to high-risk sexual practices among Lebanese males in NewYork was examined. Self-administered questionnaires were completed by a convenience sample. Relationships between AIDS-knowledge and self-efficacy and high-risk sexual practices for the 25 homosexual men were rarely significant, probably because of the small sample. The 261 heterosexual participants had statistically significant relationships between AIDS-knowledge and 9 high-risk sexual practices and between self-efficacy and 18 high-risk sexual practices. For heterosexuals, and to a lesser degree for homosexuals, high-risk sexual practices increased as drug-related behaviours and sex with prostitutes increased.

HPV DNA was detected in 78.6% of cervical carcinoma cases, 64.3% of dys/ metaplasia and 9% of normal cases. Significant correlation was found between the presence of HPV DNA and development of cervical carcinoma. HPV types 16 and 18 were detected in 60.6% of HPV-positive cervical carcinoma cases, whereas HPV31 and 33 were found in 21.2%, and HPV6 and 11 in 18.2%. Among HPV-positive dys/metaplasia cases, 55.6% were positive for HPV16 and 18, 22.3% for HPV6 and 11, and 11.1% for HPV31 and 33. Only HPV6 and 11 were detected in 4 [100%] normal biopsy specimens.
Some characteristics of the HIV epidemic in Morocco
Authors: El Harti E.
Published: September 2021

The first case of AIDS in Morocco was declared in 1986 and since then the number of AIDS cases has steadily increased. According to the Ministry of Health, the cumulative number of AIDS cases in December 2002 was 1085. HIV in Morocco is acquired mainly through heterosexual intercourse. Individuals aged between 30 and 39 years and in the regions of Marrakech and Agadir have been the most affected. Monitoring of the trend of the epidemic by sentinel surveillance surveys indicates that Morocco is still a low prevalence zone, since prevalence among pregnant women is less than 1%. The estimated number of HIV-infected people in Morocco is around 15 000. It is not clear why the epidemic here has not evolved as it has in the sub-Saharan countries where it is spreading at an alarming rate. Late introduction of HIV-1 subtype B in Morocco, which is relatively less transmissible, circumcision and reduced risk behaviours of Muslims may explain this. Nonetheless, because prevalence has increased in recent years, unless preventive measures are strengthened, the HIV epidemic will worsen in Morocco.

The legislature as First Estate of the realm represents citizens and sovereignty. It makes the law, serve as checks on the activities of the executive (oversight) and represent the citizens in constituencies. The responsibility of the Parliaments is to guarantee that accountability and transparency of government activities are maintained in order to curb misuse of public funds, corruption, while effecting good practices. It also scrutinizes the nominees for top government positions by the executive arm while it ensures that the requests sent by the executive are properly examined in order to avoid inefficiency and non-performance. However, the paper relying on secondary research method and data gathering discover that limited political will by legislators, inadequate funds, deteriorating infrastructural facilities, pressure from the Executive, predominance of inexperience legislators in the art of lawmaking and the tendency to place a higher premium of personal and pecuniary interests at the expense of public interests are antithetical to the effective legislative power of summons and appointment ratification in the National Assembly. Therefore, the paper recommended that there is a need for legislators to shun mediocrity and rise above pecuniary, sectional and party interests in favour of the protection of democracy and its practices.

Prostate cancer (PCa) is one of the leading causes of death among men in the world. Early screening is recommended as one of the prevention measures of the disease. Screening can be encouraged by Behaviour Change Communication (BCC) strategies. These strategies include mass media campaigns, participatory and interpersonal communication, advocacy and message framing. In Kenya, the Central Region is one of the leading regions in PCa prevalence rate. This study therefore examined the participatory communication strategies used in influencing men’s behaviour response towards PCa screening in the region by the Kenyan government. The study was guided by Theory of Reasoned Action. It was anchored on the Pragmatist philosophical paradigm and took a mixed method approach which involved both qualitative and quantitative designs where Key Informant Interviews, Survey and Focus Group Discussions were used to obtain data. A sample of 384 people was picked from an estimated population of 700,010 men aged 40 years and above from the region using simple random sampling. Findings showed that although health workers and communication officials appreciated the role of screening in containing the scourge, the two levels of Kenyan government (County and National) did not put in place sound participatory communication strategies for positive behaviour response to the disease. It is therefore recommended that effective participatory communication strategies for behaviour change be put in place and an annual budget allocated by the governments for this purpose.

Published: September 2021

The changing nature of communities and shifting trend of crime requires that the Nigeria police and role players seek effective strategies to address crime and insecurity in Nigeria. Fundamental changes are needed in the ways information are gathered, assessed, and redistributed by the criminal justice officials, the military and security agencies. The Nigeria police and role players have not been able to win war against crime due to the approaches adopted by them. Many have come up with different theories and recommendations to tackle insecurity in Nigeria, but the strategies were not effective. The paper focuses on the adoption of intelligence led policing strategies, approaches and technologies to combat insecurity in Nigeria. Data was obtained qualitatively; interview technique was used to elicit information from fifty-five participants. Findings reveals that, insecurity has spread to all states of Nigeria, criminals are in possession of sophisticated weapons, incessant killings and kidnappings of Nigerians are predominant, police still rely on reactive model of policing. Recommendations includes; need for increased collaboration, information gathering and intelligence sharing, need for adoption of intelligence led policing strategies, approaches methodologies, technique and technologies for tackling insecurity in Nigeria.

Actuality. The modern study of literature now does not give the answer for a question, if it is possible to create a character of a man from the life by facilities of nonfiction narration, however, it is convincing and full-blooded in the reader’s perception as an artistic image. Stating the Subject of the Study: forming of character-image of writer V. Petrov-Domontovych in the circle of the Ukrainian emigrants of the post-war wave due to their remembrances, letters, and essays. Research methodology: through the comparative hermeneutic interpretation of texts, and also later fiction texts that formed the character-image of V. Petrov. Stating the Aim of the Study. Other mechanisms of reader reception work in nonfiction genres, then in fiction, id est it becomes possible another result – the character of real V. Petrov. Results of the Study and originality. The image of Victor Petrov, formed in the memory of representatives of Ukrainian literary emigration and recorded in their memoirs and correspondence, is no less ambivalent, than images of characters in the fictional works of Victor Domontovych. Expatriate contemporaries saw their colleague differently and remembered in different situations, however, it is significant that people, in many respects disagree with moral assessments, hostile to others (as Ihor Kachurovsky, who always biased towards Yuri Sherekh-Shevelov and even repeated stereotyped allegations against him after his death) they were largely controversial in the estimation of V. Petrov. On the one hand, V. Domontovych deserved respect as a talented prose writer; on the other hand, V. Petrov was a mystery as a person. His collaboration with the Soviet special services did not cause unequivocal condemnation, since the circumstances of his "disappearance" from Munich in 1949 remained unclear. Most of those people who spoke about this event immediately after it was treated to the disappeared man with compassion because they suspected the "human beings"-brothers (Yuriy Lavrinenko) from the Soviet side. Image of V. Petrov mostly appears "split", as well as images of characters in the novels of V. Domontovich. The practical significance. In non-fictional texts, the researcher can trace the path of the formation of the image and stereotype, returning and approaching the prototype.
CRЕATIVE INTERPRETATION OF THE FОLKLОRE PHYTONYM "PERECOTYPOLE" IN THE UKRАINIAN LІTERATURE OF THE XIX CЕNTURY
Authors: Terekhova Irina
Published: September 2021

Thе relevance of this scientific statistic will begin before we start, as the Ukrainian literature of the 19th century will require more detailed reassessment. We are very important in the development of folklore warehouse, some of the folklore itself has become an unacceptable dzherel for the establishment of the actualization of artistic themes and images that were given to the dobies. Folklorе images were found in the folk culture and integrated in the creative palette of Ukrainian writing. After the hour of writing robots, a hermeneutic, descriptive, systemic and systematic method of reading has been obtained.

This аrticle is devoted to the problem of creative interpretation of the folk phytonym "perekotypole" on the basis of works of Ukrainian literature of the XIX century, in particular the article considers the ballad "Pokotypole" by A. Metlinsky, the Russian-language story nun "and the poem" We are so similar in autumn "by T. Shevchenko, L. Glibov's fable" Perekotypole ". Allusions to European romantic literature have also been identified in the study of the creative interpretation of the folklore image of the perekotypol.

In the cоurse of research it is proved that the folk tale about perekotypole is consonant with F. Schiller's ballad "Ivik's cranes". Both works show that both the steppe plant and the cranes in the sky can be silent witnesses to the ruthless violent death of a person, and in the end they help solve the murder and help punish the thief. Among all the works analyzed in the article, it is worth noting the Russian-language story "Perekatypole" by G. Kvitka-Osnovyanenko, which at one time was not republished at all and was removed from the list of the author's academic publication.

Thе study highlights the levels of transformation of the folk image of the perekotypol in various literary genres of Ukrainian literature of the XIX century: direct, secondary, indirect. The emotional and semantic load of the folk phytonym "perekotypole" in the artistic texts of the mentioned period is also determined. This image in the structure of the lіterary text serves as a silent witness to the murder (folk tales about Perekotypole, the bаllad "Pokotypole" by A. Metlinsky, "Perekotypole" by G. Kvitka-Osnovyanenko), symbolizes the state of loneliness, orphan destiny (poetry of T. Shevchenko), еmbodies the image of barrenness and alienation (L. Glшbov's fable "Perekotipole").

The study is promising in terms of further study of Ukrainian literature of the nineteenth century, its links with folklore, as well as with the European literature of Romanticism.

Apesar dos lucros auferidos no segmento de saúde suplementar, o número de segurados vinculados a ele oscilou entre 2015 e 2018, em contraste com o comportamento apresentado entre 2000 e 2014, quando só cresceu. Para compreender parte desse fluxo, isto é, a saída dos segurados desse mercado, objetiva-se analisar o tempo de permanência do segurado em planos de saúde, a partir de dados compostos por 122.381 segurados (e ex-segurados) acompanhados entre os anos de 1984 e 2018. Utilizando-se da análise de sobrevivência tradicional, por meio do estimador de Kaplan-Meier e de modelos paramétricos e semiparamétricos, destacam-se os seguintes resultados: a) a mediana do tempo de permanência no plano é de 4,62 anos; b) a massa de seguradoras é composta (ao longo dos anos observados) predominantemente por mulheres, solteiras, jovens, titulares e aderentes ao contrato de individual/familiar; c) conforme o modelo de Cox selecionado, ser homem (em relação à mulher), ser jovem (em relação ao adulto), ser dependente (em relação ao titular) e ser casado (em relação ao amasiado) aumentam o risco de saída da operadora analisada. Espera-se que esses resultados auxiliem a operadora analisada a (re)direcionar suas políticas comerciais e de subscrição de riscos.
Comparações entre métodos de desvio padrões aleatórios em experimentos fatoriais com dois níveis por fator e sem repetição.
Authors: GOMES Juliana Vieira , RIBEIRO JÚNIOR José Ivo , DIAS Camila Rafaela Gomes
Published: September 2021

Para obter a estimativa da variância aleatória em experimentos fatoriais completos e fracionados com dois níveis por fator avaliados sem repetições, Hamada e Balakrishnan (1998) fornecem uma lista de vários métodos. Assim, com base nessa revisão, o objetivo do presente trabalho consistiu em comparar as estimativas dos desvios-padrão com apenas influências das causas aleatórias de acordo com quatro métodos: de Lenth (1989), de Juan e Pena (1992), de Dong (1993) e sem nenhuma restrição aos dados, aqui denominado de desvio-padrão total. Para isso, foi simulada uma variável aleatória normal com 10.000 valores, cuja simulação foi repetida 16 vezes. Posteriormente, foram substituídos em cada um dos 16 conjuntos de dados, 0%, 1%, 2%, 3% e 4% dos valores aleatórios por outliers com o objetivo de quebrar a aleatoriedade da variável simulada. Com base na estimativa do erro percentual médio absoluto (EPMA) obtida em relação ao desvio-padrão aleatório paramétrico, concluiu-se, por meio da análise de regressão, que ela aumentou em função do aumento do percentual de substituição dos valores aleatórios por outliers, com exceção à obtida de acordo com o método de Juan e Pena (1992). Mesmo assim, para conjuntos de dados com até 3,68% de outliers, os melhores métodos de estimação do desvio-padrão aleatório (Saleatório) foram os de Lenth (1989) e de Dong (1993), por terem fornecido as menores estimativas do EPMA. Acima desse percentual e até 4% de outliers, o método de Juan e Pena (1992) mostrou-se ser melhor. No entanto, como a maior estimativa do EPMA proporcionada pelos três métodos de estimação foi muito baixa (4,00%), e ainda, como as diferenças observadas entre eles foram, praticamente, desprezíveis, concluiu-se que os três métodos forneceram boas estimativas do Saleatório e que, consequentemente, podem ser recomendados para estimar o quadrado médio do resíduo em experimentos fatoriais completos e fracionados com dois níveis por fator e com observações individuais por tratamento. Por outro lado, o método do desvio-padrão total não conseguiu evitar o efeito da não aleatoriedade sobre a estimativa do Saleatório.

Published: September 2021

The goal of the research is the development of effective methods of stabilization and determining ways to increase productive productivity in natural and designed agrocenosis. It is necessary to choose the promising composition of the pasture reclamation and forage plantations, taking into account their seasonality and the optimal seizures of the seizure of phytomass. The objects of research chosen pasture phytocenoses of the Astrakhan Volga region, the northern part of the Harabali district, the Burley plot (47° 33' N.; 47° 16' E), and vegetative sites of the hydrological complex of the Federal research center of agroecology of the Russian Academy of Sciences, Volgograd (48 ° 65' N., 44 ° 44' E.). Ecological and biological features of the dominant forage shrubs of Eurotia Ceratoides L. and Kochia Prostrata L. Schrad, Artemisia Lercheana Web., and the herbs of the Poaceae family studied according to generally accepted techniques. As a result of research, it was found that in the vegetative sites with a black soil soil substrate, the best conditions for the growth and development of herbage with the average productivity of the green mass of 1.1 t / ha for vegetation are formed, where more than 70% of the phytomass shape Poaceae. The smallest average productivity is marked on the light-chestnut soup substrate "Spring-Summer" pasture – 0.73 t / ha. Conclusion. The use of pastures is different, so the composition of agrocenoses must be chosen based on the season of operation, optimizing the load on the pasture. At the moment, the maximum adapted composition of the pasture reclamation and forage plantations, promising to create multi-tiered communities. The presented assortment serves as a stable source of additional and stable animal feed on the pasture, while at the same time rendering a positive phytomeliorative effect. The design of pasture agrocenoses allows to achieve productivity of at least 0.73 t / ha. In the structure of their phytomass, cereal species dominate, and shrubs and semi-stares perform a stabilizing role, contributing to the acceleration of the processes for the restoration of degraded pasture phytocenoses.

During the process of irrigation of wide-coverage sprinklers (WS) by the interaction of the wheels with the soil, the soil is pressed. In this case, the WS wheels impact the soil with a certain specific pressure. Specific pressure depends on a number of factors such as the length of vehicle, span length, vehicle weight, the diameter of water line, wheel contact area, determined by wheel geometry, pressure and tire type. The article carries out theoretical investigations determining the specific pressure of the wheel on the soil. It also given some recommendations connected with a number of wheels to be installed on the WS body compared with the calculated specific pressure of the designed vehicle with the standard specific pressure.

The article discusses topical issues related to the status of the Northern and Arctic territories as the most migratory-mobile. A review of recent studies is conducted, and issues that require additional study are highlighted. An analysis of the current reasons for migration makes it possible to determine the most attractive factors for migrants arriving in the Northern and Arctic ter- ritories. The “point of attraction” for them, first of all, is the labour market. At the same time, the authors state the presence of analytical problems in the study of migration processes in the Russian North. Statistical information regarding emigration and whether internal migration is practically absent in the public domain. The results of opinion polls remain the main method and key source of information on the processes of social mobility in Russia.

Рассмотрена задача упругопластического деформирования тонкостенной трубы при комбинированном нагружении изгибающим моментом, осевой силой и внутренним давлением. Решение задачи осуществлено по разработанной методике с помощью математического пакета Matcad численным методом, основанным на деформационной теории пластичности и безмоментной теории оболочек. Для упрощения решения предложено сведение двумерной задачи к одномерной задаче о деформировании балки, материал которой имеет различные диаграммы деформирования при сжатии и растяжении в осевом направлении. Проведено сравнение с результатами численного решения двумерной задачи методом конечных элементов в упругопластической постановке. Результаты расчета по инженерной методике совпадают с точным решением с точностью, необходимой для практического применения. Полученные результаты упругопластического решения для изгибающего момента в сечении трубопровода при комбинированном нагружении позволяют уточнить известное критериальное соотношение прочности сечения трубопровода с кольцевым дефектом в сторону снижения перебраковки. Применение разработанной методики позволяет ранжировать участки трубопровода с непроектным изгибом по степени близости к предельному состоянию при комбинированном нагружении изгибающим моментом, продольным усилием и внутренним давлением.

The problem of elastic plastic deformation of a thin-walled pipe under co-binned loading by bending moment, axial force and internal pressure is considered. The problem is solved by the developed method using the Matcad mathematical package by a numerical method based on the deformation theory of plasticity and the momentless theory of shells. To simplify the solution of the problem, it is proposed to reduce a twodimensional problem to a one-dimensional problem about beam deformation, the material of which has different deformation diagrams under compression and tension in the axial direction. Comparison with the results of numerical solution of the two-dimensional problem with the finite element method in the elastic plastic formulation is carried out. The obtained results of the elastic-plastic solution for the bending moment in the pipeline section under combined loading make it possible to clarify criterion ratio of the strength of the pipeline section with an annular defect in the direction of reducing the rejection. Application of the developed approach allows to rank pipeline sections with non-design bending in the steppe close to the limit state under combined loading of the pipeline with bending moment, longitudinal force and internal pressure.

Важнейшим звеном системы контроля качества нефти являются испытательные лаборатории, от компетентности которых зависит достоверность результатов измерений и эффективность управленческих решений, принимаемых с учетом полученных данных. Одним из способов подтверждения достоверности результатов измерений является проверка квалификации лаборатории посредством ее участия в межлабораторных сличительных (сравнительных) испытаниях (МСИ). В настоящей статье рассмотрены вопросы проведения таких испытаний для лабораторий организаций системы «Транснефть». Описан действующий порядок, предполагающий участие лабораторий в МСИ в регионах своего местонахождения, при этом разработкой и реализацией программы проверки квалификации занимаются сторонние организации - провайдеры МСИ. Такая практика имеет существенные недостатки, не позволяя, в том числе, систематизировать и обобщить результаты МСИ для общей оценки деятельности испытательных лабораторий ПАО «Транснефть». В статье представлен централизованный подход к проведению МСИ в ПАО «Транснефть», устанавливающий единый порядок участия лабораторий в испытаниях с целью осуществления общей оценки квалификации лабораторий, своевременной разработки и реализации предупреждающих и корректирующих мероприятий по улучшению деятельности лабораторий, усовершенствования системы контроля качества нефти на объектах ПАО «Транснефть».

The most important link in the oil quality control system are testing laboratories, the competence of which determines the reliability of measurement results and the effectiveness of management decisions based on the data obtained. One way to confirm the validity of measurement results is to verify the laboratory qualifications through its participation in interlaboratory proficiency (comparative) tests (IPT). This article considers the issues of such tests for the laboratories of Transneft system entities. The current procedure is described, which involves the participation of laboratories in the IPT in the regions of their location, while the development and implementation of the proficiency testing program is carried out by third-party IPT provider organizations. This practice has significant drawbacks, not allowing, among other things, to systematize and summarize the results of IPT for an overall assessment of the activities of Transneft PJSC’s testing laboratories. The article presents a centralized approach to conducting IPT in Transneft PJSC, which establishes a unified procedure for the participation of laboratories in tests in order to implement an overall assessment of laboratory qualification, timely development and implementation of preventive and corrective measures to improve the performance of laboratories and improve the oil quality control system at the Transneft PJSC facilities.

Weirs are the oldest and most practical structures used to control, regulate, and measure flow in rivers or open channels. The ratio of the actual discharge, smaller than the theoretical discharge due to the separation zone and boundary layer development, to the theoretically discharge is defined as the discharge coefficient (Cd). Cd values are depended on the hydraulic properties of the open channel flow and the type and geometric properties of the weir. In this study, a total of 88 weir head (H0) of the trapezoidal broad crested weir with different upstream and downstream slopes are experimentally measured and Cd values are calculated according to the weir characteristics. Calculated Cd values are estimated by using eight different input combinations with the dimensionless parameters. Three different kernel functions (Linear, Polynomial and Gaussian) of Support Vector Machines method are used. To determine the performance of the models, Root Mean Square Error (RMSE), Mean Absolute Percentage Error (MAPE), and the coefficient of determination (R2) values are employed. As a result of the study, the Gaussian kernel function is the most successful model and the input combination is H0/L (L as crest height), ɛ (H0/(H0+L)), upstream slope (α) and downstream slope (ꞵ) parameters are found to be most successful model to estimate Cd values.

Vehicles that operate at altitudes close to the sea surface by taking advantage of the ground effect enable us to overcome the hydrodynamic force exerted by the water on the vehicle, allowing us to reach general aviation speeds, while also making it possible to carry more cargo than an aircraft by taking advantage of the ground effect. In this article, the NACA 4412 profile, which has a wide usage area, high lift/drag ratio and a flat bottom surface, has been chosen as a wing concept for a hoverwing vehicle that operates by making use of ground effect. Turbulence modeling was carried out at flight altitudes where it would be exposed to ground effect with a speed of 22.22 m/s and Re=4,068x106. While the height to the ground was decreased by 0.1 starting from the height of 1 chord, the angle of attack was increased up to 10 degrees in increments of 2 degree, starting from 0 degrees, and computational fluid dynamics analyzes were performed in 2D in the Realizable K-Epsilon experimental model with the help of ANSYS Fluent. As a result of the analyzes made, the highest lift/drag value was obtained as 50 at an angle of attack of 4 degrees and at a height corresponding to 0.1 chord value.

Dusun Kerujuk adalah salah satu wilayah di Kabupaten Lombok Utara yang terdampak parah atas kejadian bencana gempa Lombok pada Juli 2018 yang mengakibatkan rusaknya berbagai infrastruktur termasuk diantaranya infrastruktur air bersih. Perbaikan infrastruktur telah diupayakan oleh pemerintah daerah setempat, namun masih terdapat kekurangan khususnya pasokan air untuk kebutuhan Masjid Nurul Hidayah dan masyarakat di sekitar masjid. Sehingga tim bermaksud membantu menambah jaringan perpipaan menuju masjid agar kebutuhan air untuk kegiatan ibadah di masjid dan bagi masyarakat yang tinggal di sekitar masjid dapat terpenuhi secara layak. Pipanisasi dimulai dari bagian intake penyadap yang diletakkan pada mata air yang ada di bagian hulu dusun, peletakan dua tandon di sekitar masjid serta pemasangan jaringan pipa yang membawa dan mendistribusikan air ke masjid dan rumah warga di sekitar masjid. Meskipun pipanisasi yang dipasang masih semi permanen namun masyarakat dapat langsung memanfaatkannya untuk memenuhi kebutuhan air bersih sehari-hari melalui jaringan pipa tersebut dalam menghadapi masa tanggap darurat gempa
