Numerical Simulation of Episodic Aseismic Slip Events as Incomplete Nucleation of Seismic Slip Due to Heterogeneous Stress Distribution
Authors: Kato Naoyuki 
Published: June 2023

ABSTRACT
Shear stress concentration at the deeper edge of a locked fault affects detachment of the fault, such as upward propagation of aseismic sliding, episodic aseismic slip events, and partial seismic rupture. Numerical simulations of earthquake cycles on a strike-slip fault were conducted using a rate- and state-dependent friction law to investigate the occurrence conditions of episodic aseismic slip events within a fault having uniform velocity-weakening friction. When the velocity-weakening zone is much wider than the critical nucleation zone size, a rupture that seismically or aseismically breaks a part of the velocity-weakening zone occurs during the interseismic period between large earthquakes. The partial seismic rupture results in a small earthquake, and the partial slow rupture results in an episodic aseismic slip event. The seismic or aseismic rupture is arrested in a low-shear-stress area, which is caused by the preceding large earthquake. The episodic aseismic slip events may be regarded as incomplete nucleation of an earthquake, because the rupture is arrested before acceleration to seismic slip, and this process may explain episodic aseismic slip events at seismogenic depths. The width of the area of preseismic sliding immediately before a simulated large earthquake is similar to that of episodic aseismic slip.

Published: June 2023

Developing students' scientific thinking in aqeedah and akhlaq (moral theology) is urgent, and a project-based learning method is needed for that process. This study explores how teachers can experience their Islamic behavior with their identities and impact project-based learning methods in learning moral theology in madrasah aliyah (Islamic high schools). This study uses a phenomenological approach to explore the Islamic behavior and identity of teachers in madrasah aliyah in developing project-based learning methods. A total of 20 moral theology teachers are involved in this study, and in-depth interviews are conducted to uncover the narratives of teachers' practices in utilizing project-based learning methods. The thematic analysis of two-group interviews with 20 teachers showed that Islamic behavior teachers' personal beliefs provided a religiously motivated narrative framework that facilitated interpreting one's experiences. Islamic behavior and teacher identity play a role in developing project-based learning methods based on moral theology. Islamic behavior is the main bond in developing project-based learning methods and the attribution of identity from God-given personality to learning in moral theology. Teacher identity, Islamic behavior, and students' scientific thinking develop when learning moral theology. Islamic behavior and the personal identity of madrasah teachers can improve project-based learning methods

Published: June 2023

Background: Mucormycosis is an angio-invasive fungal infection with high morbidity and mortality. This infection seems to be increasing during the second wave of COVID-19. Objectives of this study were to identify and characterise the fungal species causing post-covid-mycosis, to analyze the cases for underlying co-morbidities if any and to correlate the associated risk factors with the progression of disease.
Methods: Prospective observational study which constituted conventional fungal culture of 188 tissue specimens collected from clinically suspected mucormycosis patients who had history of COVID.
Results: This study noted the occurrence of disease with predominance of males (72.03%). Most common symptoms were facial/periorbital swelling, followed by facial pain and headache. Among co-morbid conditions, diabetes mellitus was the most common (71.17%). Use of steroids (65.25%), antivirals therapy (22.86%), oxygen support (11.86%) used in management of COVID patients were found to be risk factors in post-covid-mucormycosis. radiological diagnosis showed involvement of paranasal sinuses (77.11%), followed by orbit (16.94%) and brain (5.90%). Mucor spp. was isolated in 21 cases. Although commonest fungus isolated was Aspergillus, analysis of the data for last 5 years showed a significant rise of Mucormycosis cases. Mortality was seen in 17.79% cases.
Conclusions: Fungal aetiology should be kept in mind in patients with above clinical presentations with history of recent COVID-19 infection especially who received steroids.

Authors: Bhat Ashaq Hussain , Khateeb Erum Waris 
Published: June 2023

Anti-glaucoma medications form the first line of treatment in glaucoma management. However, the effectiveness of medical management for glaucoma is dented by poor adherence to anti-glaucoma medications. There is a need to elucidate the barriers to anti-glaucoma adherence and address them in order to increase effectivity of glaucoma therapy. This study is an attempt in estimating anti-glaucoma adherence behavior along with understanding various barriers to adherence. This cross-sectional, hospital based study was conducted in District Hospital Kupwara, Kashmir division, India over a period of 2 years from June 2020 to June 2022. 303 consecutive patients who were consented were included in this study. Adherence data was collected using self-reporting method in the form of visual analogue scale and 8-item morisky scale. 303 patients having glaucoma were included in this study. Mean age of patients was 53.86 ± 8.04 years ranging from 35–70 yrs. On Visual Analogue Scale, 78 percent were adherent while as 22 percent were non-adherent. As per Morisky Scale, 9 percent showed low adherence, 17 percent had medium adherence and 74 percent were having high adherence. Study patients with poor adherence reported many barriers to adherence especially forgetfulness, cost and side effects.Non-adherence is a significant problem in medical management of glaucoma seen in almost one-fourth of our patients. Educating patients and their caretakers is a must in preventing glaucoma morbidity and associated economic drain.
Pre-operative minimal-cycloplegia mydriasis for capsulorrhexis in hypermature intumescent cataract
Authors: Roy Parthasarathi , Ganguli Srisha , Tripathi Santanu Kumar 
Published: June 2023

Conventionally adrenergic-anticholinergic combination eye drops (e.g., phenylephrine-tropicamide) are used for pre-operative pupillary dilatation in cataract surgery. This achieves synergy in dilatation, but anticholinergic-induced cycloplegia makes already tense lens-capsule of intumescent cataract more taut, and completion of capsulorrhexis becomes difficult, often resulting in Argentanian flag sign, peripheral extension. An alternative mydriasis-without-cycloplegia strategy (phenylephrine) is also tried for better maintenance of mydriasis but it’s capsule-slackening effect was not thought of. Making best of both, we practice a ‘minimal-cycloplegia mydriasis’ approach (MCM) comprising of 0.25% tropicamide and 5% phenylephrine, instilled in succession. This study was planned to compare our MCM regimen with the conventional fixed-dose-combination regimen of 0.8% tropicamide and 5% phenylephrine (Standard). To compare the ease and smoothness of capsulorrhexis and relative incidence of complications, in hypermature intumescent cataract surgery, between ocular instillation of alternative ‘MCM’ regimen and the traditional ‘Standard’ regimen. The study used a prospective observational 2-arm comparison design. The study commenced with due approval of Institutional Ethics Committee. Sixty-one (61) patients (age range: 42-72yrs, number of Male: Female 19:42) undergoing hypermature intumescent cataract surgery by standard SICS+IOL technique and in whom either of two regimens, MCM or ‘Standard’ were used for papillary dilatation, were observed. Outcome analysis was done by Fisher’s Exact Test. Out of a total of 61 cases, 29 received MCM regime and 32 received ‘Standard’ cycloplegic dilator. Difference in dilatation between two groups was statistically non-significant. Frequency of completed rhexis and attainment of post-operative BCVA of 6/12 were higher with MCM regime: p&#60; 0.001 and p&#60; 0.0005 respectively. Anterior chamber reactions on first post-operative day was more frequent with MCM regime (p&#60;0.01), but was transient and cleared totally in a week. Minimal-cycloplegia dilatation regime comprising of 0.25% tropicamide and 5% phenylephrine, instilled in succession may be preferred for capsulorrhexis in hypermature intumescent cataract.

Licenciaturas a Distância, Tecnologias Digitais e Pandemia: Relatos de Práticas Docentes
Authors: Almeida Clarisse de Mendonça e 
Published: June 2023

O presente trabalho se propõe a destacar os resultados da pesquisa de doutorado “Reflexos da formação docente – uso de tecnologias digitais na prática profissional”, concluída em 2022, no âmbito do programa de Políticas Públicas e Formação Humana (PPFH-UERJ). A investigação buscou como foco central identificar se cursos de licenciatura – ofertados a distância – formam professores que promovem um uso diferenciado dos recursos tecnológicos na prática profissional em razão da metodologia que optaram estudar. Para além daquilo que aprenderam ao logo da trajetória formativa, objetivou-se perceber o significado da experiência vivida durante o contexto pandêmico, em 2020 e 2021, por meio da expressão dos próprios docentes. Como percurso metodológico, optou-se pela realização de pesquisa descritiva de cunho quantitativo e qualitativo conjugando dois métodos – entrevista semiestruturada (voltada a um grupo micro) e questionário (destinado a um grupo macro). A análise dos resultados evidenciou, entre outros pontos, uma formação – inclusive no período da pandemia - que se dá mais por curiosidade e esforços próprios do educador do que pela experiência vivida no momento de uma formação formal. Entre os principais referenciais teóricos, destacaram-se, ao longo do trabalho, Masetto (2018), Gatti (2016) e Kenski (2016) para tratar a formação docente; e Santos (2019) ao problematizar o contexto da educação e docência online como fenômenos da cibercultura.

Authors: Anchimowicz Julia , Wyżewski Zbigniew , Świtlik Weronika 
Published: June 2023

Od lat powszechnie wiadomo, że dieta ma istotny wpływ na ludzkie zdrowie, w tym na ryzyko wystąpienia nowotworów. Właściwy lub nieprzemyślany dobór składników pokarmowych może, odpowiednio, przeciwdziałać lub sprzyjać inicjacji i rozwojowi procesów nowotworowych. Tym samym, odpowiednio skomponowana dieta może wydłużyć czas życia oraz poprawić jego jakość. Korzystny wpływ na zdrowie wykazują glukozynolany (GLS) – grupa wtórnych metabolitów roślinnych występujących w warzywach z rodziny kapustowatych (Brassicaceae) takich jak brokuły, kalafior, kapusta i kalarepa. W wyniku hydrolizy GLS powstają m.in. sulforafan (1-izotiocyjaniano-4-(metylosulfinylo)-butan; SFN, ang. sulforaphane), izotiocyjanian fenyloetylu (PEITC, ang. phenylethyl isothiocyanate) oraz 3,3’-diindolilometan (DIM, ang. 3,3′-Diindolylmethane), charakteryzujące się z wszechstronnym działaniem przeciwnowotworowym. W pracy opisano postępy w badaniach wpływu wyselekcjonowanych GLS na wybrane mechanizmy epigenetyczne tj. metylację DNA, acetylację histonów i ekspresję mikroRNA oraz ich znaczenie w terapiach przeciwnowotworowych.

Актуальность. Гидромониторы нашли широкое применение при разработке россыпных месторождений в технологических схемам с оборотным водоснабжением. В настоящее время в отработку вовлекают месторождения с более сложными горно-геологическими условиями залегания. Для россыпей это, прежде всего, весьма значительное содержание глины во вмещающих породах и песках. Гидравлический способ разработки месторождений, в частности гидромониторная отбойка пород, подразумевает оборотное водоснабжение, когда технологическую воду забирают из специальных прудов-отстойников. Однако высокое содержание глины в размываемых породах, тонкодисперсные частицы которой имеют весьма длительный период осаждения в воде отстойника, значительно усложняет применение этой технологии. Известны решения для отработки месторождений в подобных условиях с управляемым содержанием тонкодисперсных грунтовых частиц в напорной воде гидромонитора, где расчет параметров отбойки пород гидромонитором предложено производить при помощи разработанной математической модели. Дальнейшее развитие предложенных решений возможно за счет внедрения в технологический процесс элементов автоматизации, в частности искусственных нейронных сетей. Цель: оценить перспективы применения технологии искусственного интеллекта для отбойки пород гидромонитором при наличии в его струе тонкодисперсных частиц. Методы: внедрение технологий искусственного интеллекта на основе искусственных нейронных сетей в технологический процесс разработки россыпных месторождений с содержанием глины во вмещающих породах и песках. Результаты. Выполнена оценка перспектив применения технологии искусственного интеллекта для управления процессом отбойки с использованием многослойной нейронной сети. Выводы. Предложенная технология позволяет оперативно управлять производительностью отбойки пород гидромонитором, регулировать расход электроэнергии, а также улучшать качество гравитационного обогащения полезного ископаемого за счет подачи на шлюзы воды с допустимым содержанием тонкодисперсных частиц, что в итоге ведет к сокращению потерь полезного ископаемого и уменьшению себестоимости процесса отбойки пород гидромонитором и всей технологии в целом, а также к улучшению показателей извлечения полезного компонента.
ОПРЕДЕЛЕНИЕ ВЛИЯНИЯ ЖИДКОСТИ ГЛУШЕНИЯ НА СНИЖЕНИЕ ФИЛЬТРАЦИОННЫХ ХАРАКТЕРИСТИК КАРБОНАТНЫХ ГОРНЫХ ПОРОД ПРИ ОСВОЕНИИ СКВАЖИН

Актуальность. Проведение ремонтных операций в добывающих и нагнетательных скважинах при неправильно подобранных компонентах жидкостей глушения может привести к существенному снижению проницаемости призабойной зоны пласта. Сохранение фильтрационно-емкостных свойств пород вблизи скважин при их глушении для проведения текущих ремонтов и последующего освоения является одной из актуальных проблем при эксплуатации фонда скважин в настоящее время. Цель: изучить влияние различных добавок в составе жидкостей глушения на фильтрационно-емкостные свойства пласта и выявить подходы по предотвращению осложнений при ремонтах скважин. Методы: эмпирические и аналитические методы. В лабораторных условиях определялся химический состав, оптическая плотность и коэффициент светопропускания жидкостей глушения и пластовой воды. Моделирование фильтрации пластовых флюидов выполнялось на установке исследования керна. Результаты. Основной причиной снижения проницаемости призабойной зоны при глушении скважин в Тимано-Печорской нефтегазовой провинции является высокое содержание ионов железа в пластовых водах. Следует отметить, что воды фаменского горизонта содержат 60–70 мг/л железа. Для решения проблемы ухудшения фильтрационных характеристик призабойной зоны необходимо значительно снизить содержание железа в жидкости глушения или предотвратить его выпадение. Анализ результатов изменения оптической плотности растворов позволяет говорить об эффективности применения оксиэтилидендифосфоновой кислоты и композиции АКСИС-КС для осветления и стабилизации жидкости глушения с содержанием гидратируемых ионов железа до 70 мг/л. На основании проведенных фильтрационных экспериментов для снижения негативного влияния растворенного железа на проницаемость пласта можно рекомендовать к использованию стабилизатор железа оксиэтилидендифосфоновой кислоты в концентрации 2,0 % (при содержании ионов железа до 70 мг/л) и гидрофобизатор комплексного действия Нефтенол-К в концентрации 1 %.
