Shallow seismic characteristics and distribution of gas in lacustrine sediments at Lake Erçek, Eastern Anatolia, Turkey, from high-resolution seismic data
Authors: Toker Mustafa , Tur Hüseyin 
Published: May 2021

Abstract
The high-resolution analysis of single-channel, seismic reflection data from Lake Erçek (Eastern Anatolia) revealed a wide range of shallow gas anomalies consisting of enhanced reflections, seismic chimneys, acoustic blanking/acoustic turbidity, strong reflectors, and pockmarks, including both surface and buried pockmarks. The enhanced reflections are represented by the higher-amplitude reflection patterns resulting from high acoustic impedance variations. They are mostly clustered in the NW-corner of the lake. Seismic chimneys are represented by vertical and thinned columnar disturbances of amplitude blanking and mostly occurred in deep basinal and faulted sections in the West and East of the lake. Some seismic chimneys, occurring together with pockmarks, represent vertical vent activations. Acoustic gas-masking was represented by chaotic and diffuse seismic reflection patterns, including acoustic blanking and acoustic turbidity. As diffuse acoustic turbidity indicates gas-charged sediments, columnar disturbances showing acoustic blanking indicate degassing of the sediments. These features extend from SE to NW, coinciding with the deep basin morphology of the lake. A very local strong reflector was identified in the western section of the lake, simulating the lake floor. This reflector is due to extended enhanced reflections, suggesting shallow free gas. Pockmarks observed in the lake are structurally classified into the two distinct types; surface (active) pockmarks found in the SE-part of the lake and buried (passive) pockmarks found in the NW. The former enlarge through deeper gas reservoir feedback, as the layering is impermeable, while the latter have resulted from a cessation of the reservoir feedback mechanism and/or permeable layering. In the lake, shallow gas distribution is controlled by faults, that provide the faulting-driven depositional control and earthquakes, that provide the seismicity-driven overpressure control. The shallow gas is then both vertically and horizontally distributed and, finally, distribution is shaped by asymmetric depositional and stratigraphic factors. This study of Lake Erçek presents complementary information about a possible origin of observed shallow gas and is important in identifying the pockmark types to be targeted for oil/gas exploration and valuable geochemical proxies.

To date, the role of human papillomavirus (HpV) in the development of lung cancer is still under investigation. The available published data do not provide evidence of the involvement of HpV in lung cancer pathogenesis. In Russia, there are no reports regarding the studies of viral contribution to lung carcinogenesis.The aim of the present study was to examine the presence of high-risk HpV infection in patients with non-small cell lung cancer (NSCLC).Material and Methods. The study included 30 patients with histologically verified stage IIBIIIA NSCLC. Normal and tumor lung tissue samples as well as whole blood samples from each patient were used. dNA was isolated from tissue samples using the QIAamp dNA mini Kit (Qiagen, Germany). Amplisens® reagent kits (Moscow, Russia) were used for dNA isolation and genotyping.Results. The presence of HpV dNA was detected in 3 (10.0 %) patients. HpV dNA was not detected in 27 (90.0 %) patients. HpV-16 genotype was observed in 2 HpV-positive patients, and HpV-33 was observed in 1 patient. A clinically insignificant viral load was found in almost all HpV-positive samples. The assessment of the virus integration in HpV16-positive lung cancer patients revealed mixed and integrated forms of the virus in the tumor tissue of these patients. The 5-year metastasis-free survival rate in all HpV-positive patients was 100 %.Conclusion. Our data showed HpV dNA prevalence rate of 10 % among NSCLC patients in the Russian population. The presence/absence of a viral component for lung cancer patients is a clinically significant parameter.

Авторами обосновываются актуальность и востребованность изучения самореализации по результатам запросов из научной базы SciVal. Проанализированы данные распределения исследований тематического кластера по странам, вузам мира, по журналам из перечня научной базы Scopus. Проведен обзор отечественных и зарубежных научных публикаций по проблеме изучения социальной самореализации волонтеров, раскрываются мотивы их участия в добровольческих объединениях и личностные особенности.
В исследовании приняли участие 60 подростков (30 девушек и 30 юношей) – участников социально значимых проектов, проводимых на территории Ростовской области. Средний возраст респондентов составил 15,5 лет. Стаж волонтерской деятельности варьировал от 2 до 5 лет. Методический инструментарий: многомерный опросник самореализации личности С. И. Кудинова и авторская анкета «Смыслообразующие мотивы самореализации».
В ходе проведенного исследования были выявлены следующие закономерности: у девушек-волонтеров на статистически значимом уровне выше показатели социальной самореализации, чем у юношей-волонтеров. Независимо от половой принадлежности для подростков-волонтеров характерен средний уровень структурированности социальной самореализации. В зависимости от половой принадлежности и по мере взросления подростков – участников социально значимых проектов компоненты социальной самореализации претерпевают изменения: девушки-волонтеры становятся более консервативными, а у юношей-волонтеров снижаются личностные барьеры. У юношей-волонтеров преобладающим мотивом социальной самореализации является утилитарно-прагматический мотив, а у девушек-волонтеров – коммуникативный мотив.
Выявленные закономерности могут быть использованы для построения эффективного психолого-педагогического сопровождения подростков по формированию целостной системы поддержки инициативной и талантливой молодежи и вовлечения молодых людей в социальную практику.
Академическая прокрастинация: аспекты откладывания выполнения учебных заданий студентами
Authors: Попова Дарья И. , Беликова Маргарита Е. 
Published: May 2021

В статье авторы рассматривают академическую прокрастинацию как серьезную проблему студентов высших учебных заведений, которая негативно сказывается на их психологическом состоянии и на результатах учебной деятельности. Актуальность исследования заключается в распространенности проблемы. В исследованиях на данную тему отмечается, что очень большой процент студентов подвержен академической прокрастинации. Новизна исследования заключается в комплексном изучении у студентов гуманитарного профиля проявлений и причин академической прокрастинации и связанных с ней эмоциональных состояний.
Исследование проводилось с помощью авторской анкеты-опросника на выборке студентов гуманитарных специальностей (в количестве 128 человек) в декабре 2020 года.
В результате были получены и проанализированы данные по нескольким направлениям: 1) проявления прокрастинации; 2) причины прокрастинации; 3) эмоциональные состояния, сопровождающие прокрастинацию; 4) последствия для учебного процесса; 5) пути преодоления состояния прокрастинации.
Было выявлено, что академическая прокрастинация проявляется у респондентов прежде всего в откладывании выполнения учебных заданий и подготовки к экзаменам. Наиболее частыми причинами такого откладывания респонденты назвали трудоемкость и сложность задачи, а также вид задания: чаще всего откладывают письменные задания. Эмоциональный аспект академической прокрастинации обычно характеризуется у респондентов тревогой и чувством вины. Приступать к выполнению задания студентов чаще всего побуждают две причины: тревога о негативных последствиях того, что работа не будет сдана в срок, и желание поскорее избавиться от задачи, которая вызывает напряжение, оставаясь невыполненной. Также было проанализировано влияние академической прокрастинации на учебный процесс. Оказалось, что более трети опрошенных хотя бы несколько раз пропускали занятия по причине несделанного задания.
Таким образом, академическая прокрастинация является фактором, который значительно осложняет учебную деятельность студентов вузов.

Objective: Algae is the undisputed treasures of the sea and are a valuable raw material, providing unlimited opportunities for new drug discoveries. Marine algal products are in demand in the international market in the form of standardized algal extracts or semi-finished products.
Methods: Aqueous and methanolic extracts of Oedogonium globosum and Oedogonium intermedium species were obtained maceration and hot percolation. The active principles from O. intermedium were isolated, purified by column chromatography, and characterized by spectral studies IR, λmax, 1HNMR and MS. The extracts of Oedogonium species were screened for their anti-microbial effects, acute dermal irritation and wound-healing activity studies.
Results: Comparing to Oedogonium intermedium (45 %, 90 %, 87 %), very low extractive yields were obtained for Oedogonium globosum (10.80 %, 37 %, 28 %). At phytochemical screening, Terpenoids, Flavanoids and, Glycans were found to be present in a significant amount and upon their isolation, it was found that a collection of fractions from cold extract with Rf value in the range 0.32-0.34 as Glycans and those from the hot extract with 0.40-0.72 as Flavanoids and those from methanolic extracts with 0.23, 0.44 and 0.71 as for Terpenoids. Anti-bacterial study revealed out the fact of Oedogonium species could give higher inhibition to gram-positive than for gram-negative bacteria at (10 μg/10μl/disc) concentration. No symptoms of systemic toxicity and mortality were observed. Silver sulfadiazine, more potent in wound closure, the effect of methanolic extracts of O. intermedium (87 %) was almost at par to the standard (95 %) in action and significantly greater than O. globosum (72 %, P<0.05).
Conclusion: Admittedly, Oedogonium type algal species can be known as medicinal algae with a plethora of a wide range of pharmacological activities. Thus, this research work may be considered further for extensive innovative discoveries of new lead molecules and any other pharmacological activities, in the future.

Published: May 2021

Objective: The main objective of this study is to investigate the antioxidant and nephroprotective efficacy of moringa oleifera seed extract (MOSE) against cisplatin which induced acute renal injury.
Methods: Forty male Wister rats were equally segregated into 4 groups (10 rats per group): group I (0.5 ml of sterile saline orally), group II (200 mg MOSE/kg b. wt orally for 10 consecutive days), group III (7.5 mg cisplatin/kg b. wt/intraperitonially as a single dose on the 5th day of the experiment) and group IV (200 mg moringa oleifera seed extract (MOSE)/kg orally for 10 d followed by 7.5 mg cisplatin/kg body weight/intraperitonially once as a single dose on the 5th day of the experiment. Serum biochemical analysis of renal biomarkers (urea, uric acid, and creatinine), oxidative stress markers (malondialdehyde [MDA]), a crucial antioxidant enzyme (catalase) and the expression of renal activity interleukin (IL)-6, (IL)-10 and Tumer necrotic factor (TNF-α) mRNA were determined. Histopathological examination of renal tissue was done.
Results: Cisplatin induced renal damage, increased renal biomarkers (urea, creatinine and uric acid)(375.87±1.65, 5.238±0.25, 4.47±0.25). Tissue concentrations of malondialdehyde, IL-6 and TNF-α.(387.56±0.97, 2.188±0.20, 3.06±0.27)compared to control group(140.58±1.25,0.938±0.017, 1.24±0.17), (163.99±1.34, 1.008±0.05, 0.982±0.026) Moreover, cisplatin induced significantly down-regulation of anti-inflammatory (IL-10) and catalase (0.780±0.47, 1.62±0.06) compared to control one (1.010±0.02, 3.12±0.11),. The histopathological examination showed renal tissue damage and degeneration of tubules in the cortical portion in cisplatin group. However, interestingly concurrent adminsteration of the MOSE with cisplatin can alleviated the renal damage, oxidative stress and renal toxicity caused by cisplatin.
Conclusion: These results suggest that the antioxidant and the anti-inflammatory effects of MOSE alleviate the cisplatin-induced nephrotoxicity.
