Sitagliptin ameliorates ER stress in diabetic kidney disease through upregulation of SIRT1
Authors: Zhang Qunzi , Jia Junjie , He Li , Fan Ying , Wang Niansong
Published: August 2021

Objectives

Endoplasmic reticulum (ER) stress plays a significant role in the progression of diabetic kidney disease (DKD), and dipeptidyl peptidase-4 (DPP4) inhibitors are widely used antihyperglycemic agents, exerting renal beneficial effects in DKD. Here, we investigated the role of DPP4 inhibitor Sitagliptin (Sita) in ER homeostasis in the kidneys of diabetic DBA2/J (D2) mice and in albumin-stimulated HK-2 cells.

Methods and Results

ER stress was observed both in vivo and in vitro, as reflected by notably increased glucose-regulated protein of 78 kDa (GRP78), CHOP, high phosphorylation of PERK (p-PERK), and cleaved caspase3 (c-CASP3), whereas Sita effectively attenuated these disorders. Meanwhile, Sita increased the expression of SIRT1 both in vivo and in vitro. To further validate the potential effects of SIRT1 in regulating ER stress, we regulated SIRT1 by siRNA and overexpressed plasmids in albumin-overloaded HK-2 cells. Elevated SIRT1 alleviated albumin-induced ER stress, while decreased SIRT1 further aggravated ER stress in albumin-treated HK-2 cells.

Conclusion

The results suggest that a novel mechanism links the DPP4 enzyme to ER stress during tubular injury in DKD and highlight that SIRT1 may be a potential target for managing DKD.
Inverse Function Theorem. Part I1
Authors: Nakasho Kazuhisa , Futa Yuichi
Published: August 2021

In this article we formalize in Mizar [1], [2] the inverse function theorem for the class of C
1 functions between Banach spaces. In the first section, we prove several theorems about open sets in real norm space, which are needed in the proof of the inverse function theorem. In the next section, we define a function to exchange the order of a product of two normed spaces, namely 𝔼 ↶ ≂ (x, y) ∈ X × Y ↦ (y, x) ∈ Y × X, and formalized its bijective isometric property and several differentiation properties. This map is necessary to change the order of the arguments of a function when deriving the inverse function theorem from the implicit function theorem proved in [6].

In the third section, using the implicit function theorem, we prove a theorem that is a necessary component of the proof of the inverse function theorem. In the last section, we finally formalized an inverse function theorem for class of C
1 functions between Banach spaces. We referred to [9], [10], and [3] in the formalization.
The Non-Unicity of the Film Thickness in the Hydrodynamic Lubrication: Novel Approach Generating Equivalent Micro-Grooves and Roughness
Authors: Gadari M. El , Hajjam M.
Published: August 2021

Since the 1960s, all studies have assumed that a film thickness “h” provides a unique pressure field “p” by resolving the Reynolds equation. However, it is relevant to investigate the film thickness unicity under a given hydrodynamic pressure within the inverse theory. This paper presents a new approach to deduce from an initial film thickness a widespread number of thicknesses providing the same hydrodynamic pressure under a specific condition of gradient pressure. For this purpose, three steps were presented: 1) computing the hydrodynamic pressure from an initial film thickness by resolving the Reynolds equation with Gümbel’s cavitation model, 2) using a new algorithm to generate a second film thickness, 3) comparing and validating the hydrodynamic pressure produced by both thicknesses with the modified Reynolds equation. Throughout three surface finishes: the macro-shaped, micro-textured, and rough surfaces, it has been demonstrated that under a specific hydrodynamic pressure gradient, several film thicknesses could generate the same pressure field with a slight difference by considering cavitation. Besides, this paper confirms also that with different ratios of the averaged film thickness to the root mean square (RMS) similar hydrodynamic pressure could be generated, thereby the deficiency of this ratio to define the lubrication regime as commonly known from Patir and Cheng theory.
Effects of Pressure Gradient on Convective Heat Transfer in a Boundary Layer Flow of a Maxwell Fluid Past a Stretching Sheet

Published: August 2021

The pressure gradient term plays a vital role in convective heat transfer in the boundary layer flow of a Maxwell fluid over a stretching sheet. The importance of the effects of the term can be monitored by developing Maxwell’s equation of momentum and energy with the pressure gradient term. To achieve this goal, an approximation technique, i.e. Homotopy Perturbation Method (HPM) is employed with an application of algorithms of Adams Method (AM) and Gear Method (GM). With this approximation method we can study the effects of the pressure gradient (m), Deborah number (β), the ratio of the free stream velocity parameter to the stretching sheet parameter (ɛ) and Prandtl number (Pr) on both the momentum and thermal boundary layer thicknesses. The results have been compared in the absence and presence of the pressure gradient term m . It has an impact of thinning of the momentum and boundary layer thickness for non-zero values of the pressure gradient. The convergence of the system has been taken into account for the stretching sheet parameter ɛ. The result of the system indicates the significant thinning of the momentum and thermal boundary layer thickness in velocity and temperature profiles. On the other hand, some results show negative values of f '(η) and θ (η) which indicates the case of fluid cooling.
New Iterative Method of Solving Nonlinear Equations in Fluid Mechanics
Authors: Paliivets M. , Andreev E. , Bakshtanin A. , Benin D. , Snezhko V.
Published: August 2021

This paper presents the results of applying a new iterative method to linear and nonlinear fractional partial differential equations in fluid mechanics. A numerical analysis was performed to find an exact solution of the fractional wave equation and fractional Burgers’ equation, as well as an approximate solution of fractional KdV equation and fractional Boussinesq equation. Fractional derivatives of the order α are described using Caputo's definition with 0 < α ≤ 1 or 1 < α ≤ 2. A comparative analysis of the results obtained using a new iterative method with those obtained by the Adomian decomposition method showed the first method to be more efficient and simple, providing accurate results in fewer computational operations. Given its flexibility and ability to solve nonlinear equations, the iterative method can be used to solve more complex linear and nonlinear fractional partial differential equations.

Authors: Зиганшин Ирек Ильгизарович , Иванов Дмитрий Владимирович , Хасанов Рустам Равилевич
Published: August 2021

Дана характеристика осадконакопления и основных свойств разнотипных донных отложений озер Саралинского участка Волжско-Камского биосферного заповедника, образованных в середине ХХ в. при затоплении понижений II надпойменной террасы р. Волга водами Куйбышевского водохранилища. В структуре современных осадков преобладают песчанистые илы; в ряде озер встречаются погребенные торфянистые илы и отложения из макрофитов. Накопление в ложе озер осадкообразующего материала преимущественно происходит за счет поступления терригенного вещества с территории водосбора, а у ряда озер, не утративших связь с водохранилищем, – речного аллювия. Общая мощность вскрытых при грунтовой съемке отложений не превышала 50 см. Средняя скорость осадконакопления в озерах варьирует от 1.0 до 2.5 мм/год, а максимальная достигает 7.5 мм/год. За 60 лет своего существования озера заилились в среднем на 15%.

Determining the effect of time dependent and time independent factors on pneumonia of children under five in North west Ethiopia
Authors: Tesfaw Lijalem Melie , Derebe Muluwerk Ayele , Fenta Haile Mekonnen
Published: August 2021

Background. Lower Respiratory Tract Infections including pneumonia are the fourth cause of death globally. In Ethiopia, pneumonia is the leading cause of death for children under five. However, so far, only a few studies that used longitudinal design and time dependent covariates determined the significant factors of pneumonia. This study sought to determine whether respiratory rate changes differed for under five-year-old pneumonia patients who had been receiving different treatments over time and whether the change was effected by time dependent and independent covariates.
Methods. A longitudinal study design involving marginal Poisson regression models and conditional Poisson regression models was used. After comparing the two, the final interpretation was made using a conditional Poisson regression model owing to its relative powerfulness.
Results. Four hundred and fifty-three under five pneumonia patients were included, of which 44.37% were female. It is found that, compared to rural children, urban children had an estimated mean respiratory rate decrease of 3%. It is also found that, compared to children whose mother practiced only exclusive breastfeeding in the first six months, children whose mother practiced both breastfed and complementary were more likely to be exposed to pneumonia. The estimated mean respiratory rate of children having asthma was 1.073 times that of children who had diarrhea.
Conclusions. In northwest Ethiopia, weight, residence, previous disease history, breastfeeding and temperature are significant factors of pneumonia among children under five. The effectiveness of treatments was dependent on the number of times children visited the hospital. A significant variation of baseline pneumonia status among under five pneumonia patient children was noted in the hospital.

Authors: Vural Sema , Genç Dildar Bahar , Kebudi Rejin , Doğan Öner , Karaman Serap
Published: August 2021

Background. Chemotherapy with high dose methotrexate is the mainstay of treatment for Burkitt lymphoma (BL), especially to manage central nervous system (CNS) disease. However, methotrexate administration requires close drug level monitoring for appropriate folinic acid rescue, which might not be readily available in all centers. In this study, we assessed the long-term treatment outcomes of a modified Non-Hodgkin lymphoma (NHL)-Berlin-Frankfurt-Munster (BFM) 90 regimen in pediatric high-risk BL without CNS involvement.
Methods. Between 1999 and 2011, 42 patients (median age: 7 years) with advanced-stage BL were treated with modified NHL-BFM 90 regimen (methotrexate at a dose of 1 g/m2). Demographic data, stage, lactate dehydrogenase (LDH) and treatment results were retrospectively evaluated. The patients were assessed for toxicity, survival and CNS recurrence.
Results. Thirty-six patients had Stage III and six had Stage IV disease, respectively. The median LDH level was 1,432 IU/L. Four patients died of infectious and metabolic complications. One patient had local recurrence at the 48 < sup > th < /sup > month of the follow-up and he is in the second remission for 72 months. In Kaplan-Meier analysis, the overall survival and event-free survival rates at 10 years were found as 90 % and 88 %, respectively. None of our patients died of treatment failure.
Conclusions. The administration of the reduced dose of methotrexate seems to not compromise treatment success nor increase the risk of CNS recurrence in high-risk BL without CNS involvement. The limitation of the study is that it is not randomized. Our treatment scheme might be considered for centers without methotrexate measurement facility.
Massive true thymic hyperplasia in a 3-month-old infant: case report and literature review
Authors: Yang Min , Zeng Lin , Ji Yi , Xiang Bo , Xu Zhi-Cheng
Published: August 2021

Background. True thymic hyperplasia (TTH) is characterized as a distinct increase in both size and weight of thymus, which retains normal microscopic and immunohistochemical appearances. Massive true thymic hyperplasia (MTTH) is an extremely rare but significant subtype of TTH in pediatric ages due to its potentially serious consequences. It was reported that the age of cases with MTTH was predominantly between 1 and 15 years, while those before 1 year rarely occurred. By presenting the diagnosis and treatment process of our case as well as reviewing the related literature, we aimed to analyze the clinical characteristics of MTTH for patients younger than 1 year.
Case. A 3-month-old male infant was admitted to our department with a chief complaint of gradually increasing polypnea over 9 days, whose preoperative imaging examination showed a large intrathoracic soft tissue shadow predominantly on the right side. The percutaneous fine-needle biopsy guided by ultrasonography was performed to identify its diagnosis. However, proliferating lymphocytes and Hassall`s corpuscles were seen microscopically in the biopsy tissues, which were immunohistochemically positive for CD3, CD19, CD20, CD99, TdT, PCK and Ki67 ( > 90%). Due to the aggravating symptoms, a second operation with total thymectomy was carried out successfully for this infant, which confirmed the diagnosis of TTH again by both morphological study and immunohistochemical staining from the surgical specimen.
Conclusions. By reviewing the literature, there were only 10 cases with MTTH reported between 1975 and 2020 for children aged < 1 year of life, together with our present one. In MTTH patient`s sex had an obviously male predominance (70%). Nine out of 10 presented initial symptoms or signs related to respiratory system and 6 patients showed respiratory distress. All patients were successfully treated by surgical thymectomy without any postoperative complications. The prognosis of MTTH was very successful.

ABSTRACT

Most of the students of MTs Miftahul Ulum come from a background of duck farmers and breeders. Students lack family support regarding the importance of education. This is shown by many students who drop out of school or even marry early. Based on the problem, a solution is needed, namely introducing students to entrepreneurship and management through training in making salted eggs as a provision for life skills. The service team provides assistance during the salted egg making training. The activity of making salted eggs is supported by the student's family background as duck breeders. Salting is one way to preserve eggs to make them more durable. Preserved salted eggs with kitchen ashes. The results of the dedication showed that the students were enthusiastic and happy with the training activities. It is hoped that this training will increase students' pocket money and become provisions for students after graduation.

Published: August 2021

Introduction Despite many health benefits from dietary fiber, inadequate intake is prevalent among elderly population.  This study aims to obtain the pattern of fiber intake in different socio-demographic backgrounds among elderly in Jakarta area, Indonesia and its’ associated factors.   

Methods: A cross-sectional study was conducted among elderly aged > 60 years in 5 community health center across Jakarta province.  A total of 126 elderly were interviewed using two non-consecutive 24-h dietary recall methods to obtain dietary intake data.  Socio-demographic backgrounds on age, sex, education, income, marital status, and energy intake were assessed using structured questionnaire.  Mann-Whitney or independent t-test was performed to measure the different of fiber intake in each socio-demographic variable. Linear regression test was performed to analyze the variables that associated with fiber intake.

Results: Majority of 98.4% of elderly have total fiber intake <80% of Indonesian Recommended Dietary Allowance (RDA) with average intake of 6.6 g/d.  Lower fiber intake was significantly found in females, widowed/separated, have lower education and income, and have inadequate energy intake.  Factors associated with total fiber intake were income (adjusted β=0.20, p=0.01) and energy intake adequacy (adjusted β=0.65 p=0.00).

Conclusion: Fiber intake among elderly in urban area is inadequate and the pattern was worse in the low socio-demographic settings.  By this finding, it is important to give priority to the socially disadvantages group when formulating nutrition intervention policy in this population setting.

Published: August 2021

Introduction Obesity is a serious hurdle facing by the world nowadays. Even though so many efforts have been done, yet the prevalence is keep rising. Intermittent fasting is seen as an effective and optimal approach for improving nutrition status without undesirable side effect.

Objective to identify the effect of intermittent fasting on fat mass and fat free mass among obese adult.

Methods: a literature exploration was conducted from January to October 2020 by searching the relevant studies from several databases.

Results: many human clinical trials recommended that IF affects beneficial on body composition and body weight. Consuming calorie only in a certain time frame per day for 4-12 months put the body into a fast metabolism which influence the reduction of fat mass from 0.03–16.4% intervention and increasing of fat free mass for around 0.64 to 0.86%.

Conclusion: intermittent fasting may reduce fat mass and increase fat free mass in obese adult through the reduction of energy intake (fasting) and the benefit to adipose tissue, liver, pancreas, skeletal muscle, and the brain.
Association between apolipoprotein B and dietary fibers
Authors: Gunawan Almira Devina , Bardosono Saptawati , Mudjihartini Ninik
Published: August 2021

Introduction Global awareness to the importance of natural fibers in vegetables and fruits are still generally very low. Indonesian people consume less fibers, which has been associated with the development of heart disease. Heart disease has been known as the leading cause of morbidity and mortality. Apolipoprotein B (ApoB) is a component of atherogenic particles that can be used as a marker for an increased risk of cardiovascular disease. Researches on apoB profile and its relationship with fiber intake has provided inconsistent results. This is an article review of the current literatures on the relationship between dietary fiber and serum apoB levels.

Methods: This is an article review of the current literatures on the relationship between dietary fiber and apoB. We searched PubMed and Google Scholar using keyword “dietary fibers” and “ApoB” to capture meta-analyses, observational and experimental studies. A total of 97 publication and abstracts were screened for this review. After careful screening, nine studies were finally included.

Results: Two studies did not find associations between dietary fiber and serum apoB, while other seven found the association. Dietary fiber has been reported to be involved in the metabolism of serum cholesterol and blood pressure; hence, the deficiency of dietary fiber intake is believed to contribute to the epidemic of cardiovascular diseases. Several factors including nutritional status, dietary diet pattern, age, gender, physical activity, and smoking habits might influence the relationship between dietary fiber and serum apoB.

Conclusion: More studies are required in the future for better understanding on the effect of dietary fiber on the apoB; hence, the risk of cardiovascular diseases.

Published: August 2021

Description of the subject. Phenolic compounds are very important to the antioxidant capacity of plant species. Phenolic compounds and hence antioxidant capacity are commonly measured in the laboratory using indirect methods that involve several stages and chemicals. Objectives. This study aims to identify species with high content of phenolic compounds and antioxidant capacity and to measure these parameters in the leaves of fruit species using near-infrared spectroscopy (NIRS). Method. A total of 68 samples of different varieties of Prunus avium, Prunus cerasus, Malus domestica, Prunus domestica, Pyrus communis, Vitis vinifera, Ficus carica and Corylus avellana were investigated. The dried ground leaves were scanned in reflectance mode and the phenolic compound content (total phenolic compounds, total flavanols and total flavonols) and antioxidant capacity (2-2-diphenyl-1-picrylhydazil [DPPH] and oxygen radical absorbance capacity [ORAC]) were determined. Results. Great variability of phenolic compound content and antioxidant capacity was observed between species (inter-species) and between varieties (intra-species). The spectra with and without pre-treatments were tested to correlate with the phenolic compound content and antioxidant capacities. The pre-treatments tested showed a slight improvement in statistical parameters (R²CAL > 0.75; R²CV > 0.21; RPD > 1.1). Conclusions. The results suggest that NIR spectroscopy with chemometric approaches could be used to rapidly estimate the phenolic compound content and antioxidant capacity of the leaves of fruit species. The species evaluated in this study were shown to be a rich source of phenolic compounds and antioxidants.

Published: August 2021

Introduction. Le présent travail dresse une synthèse des connaissances sur le genre Dialium (Fabaceae, Dialioideae) dans la région guinéo-congolaise. Il examine plus particulièrement la possibilité de valoriser durablement le bois de ces espèces et les coproduits de leur transformation en vue de diminuer la pression sur d’autres espèces de bois durs dont les populations se raréfient. Littérature. Bien qu’il n’existe pas de consensus parmi les botanistes, le genre Dialium comprendrait 44 espèces, dont 22 espèces seraient inféodées à la région guinéo-congolaise. Les différences entre espèces sont parfois ténues et les descriptions reposent sur un nombre limité d’individus. Les espèces vivant en forêt dense humide ont des structures de populations équilibrées. À part leur mode de dispersion, lequel est zoochore, les connaissances écologiques sont très lacunaires. L’absence de données sur la dynamique des populations est particulièrement problématique dans le cadre de l’aménagement durable des forêts. Les propriétés physiques, mécaniques et biochimiques du bois ont seulement été caractérisées pour un nombre limité d’espèces. Conclusions. Cet article, en proposant une clé de détermination des espèces de la région guinéo-congolaise, a tenté de clarifier la taxonomie du genre Dialium tout en soulevant la nécessité de mener des études génétiques complémentaires. En Afrique centrale, certaines espèces du genre Dialium sont localement abondantes et semblent se régénérer correctement. Elles offrent de nombreuses perspectives de valorisation car leur bois est très durable et pourrait renfermer des molécules intéressantes. Les recherches à venir devraient se concentrer en priorité sur la dynamique démographique de ces espèces et sur les propriétés de leur bois.

Background: Use of food labels can help consumers to make informed choices on foods they purchase which could have beneficial role in protection from obesity and diet related chronic diseases. The aim of this study was to investigate food label use in the Palestinian society along with related factors. Methods: Electronic survey was distributed on social media platforms to Palestinian society in West Bank, Gaza, and other places of Palestinian communities’ presence. The survey collected data on demographic variable, obesity, chronic disease history and nutritional deficiencies. In addition to food label use information. Data was analyzed using IBM SPSS 21 software. Results: We included 271 participants in our study, mean age of our study group was 25.6±10 y, mainly females. Obesity was present in 24.4% of the study group, whereas 42.8% reported they were not satisfied with their current weight and 49.4% reported they attempted to lose weight. The prevalence of label use in our study group was 61.6%. Majority of label users obtained information on amount of calories, serving size, fat, sugar, vitamins and minerals content. Very few obtained information on sodium, saturated fat and transfat in food product. Food label use was significantly related to age (p<0.05) and healthy dietary patterns (p<0.05), but was not related to obesity and chronic disease. Conclusion: Our study indicate high rate of label use among Palestinians with some gaps in nutrition information obtained.

Моделювання цетанового числа дизельних біопалив для автомобільного транспорту
Authors: Колодницька Руслана Віталіївна
Published: August 2021

Зниження випуску автомобілів з дизельними двигунами в Європі, для яких характерні великі викиди як оксидів азоту, так і вуглекислого газу, призводить до того, що автомобілі з цими двигунами все більше й більше продаються в Україні. В містах України все ще використовуються «маршрутні» автобуси з дизельними двигунами, і транспортні компанії намагаються замінити менші автобуси на більші з тим же самим дизельним двигуном. В такій ситуації використання біодизельного палива є перспективним для України. Цетанове число палива – одна із самих важливих характеристик палива, що свідчить про його здатність до згоряння в ДВЗ. Точне значення цетанового числа дизельного біопалива дуже важливе для моделювання характеристик згоряння цього палива. Цетанові числа дизельного біопалива та його компонентів є базою для розрахунків затримки займання цих палив. Переважно дизельне біопаливо має більші значення цетанового числа, ніж дизельне паливо. В роботі виконано аналіз цетанових чисел дизельних біопалив, що виготовлені з використаної олії. Запропоновано формулу для підрахунку цетанового числа таких палив з огляду на їх молекулярний склад. Одержано гарне узгодження даних моделювання цетанового числа з експерементальними даними за результатами спектрального аналізу палив. Підраховано цетанові числа для компонентів (метилових ефірів жирних кислот), з яких складається дизельне біопаливо. Для того, щоб уникнути поганого розпилювання, біодизельне паливо змішується з дизельним паливом. Відновлювальне дизельне паливо має меншу густину, але більші значення цетанового числа, ніж викопне дизельне паливо. Отже, дослідження паливних характеристик сумішей дизельного біопалива з відновлювальним паливом може бути темою наступних досліджень.

Background

School attendance during the COVID-19 pandemic is intensely debated.

Aim

In November 2020, we assessed SARS-CoV-2 infections and seroreactivity in 24 randomly selected school classes and connected households in Berlin, Germany.

Methods

We collected oro-nasopharyngeal swabs and blood samples, examining SARS-CoV-2 infection and IgG antibodies by RT-PCR and ELISA. Household members self-swabbed. We assessed individual and institutional prevention measures. Classes with SARS-CoV-2 infection and connected households were retested after 1 week.

Results

We examined 1,119 participants, including 177 primary and 175 secondary school students, 142 staff and 625 household members. SARS-CoV-2 infection occurred in eight classes, affecting each 1–2 individuals. Infection prevalence was 2.7% (95% confidence interval (CI): 1.2–5.0; 9/338), 1.4% (95% CI: 0.2–5.1; 2/140), and 2.3% (95% CI: 1.3–3.8; 14/611) among students, staff and household members. Six of nine infected students were asymptomatic at testing. We detected IgG antibodies in 2.0% (95%CI: 0.8–4.1; 7/347), 1.4% (95% CI: 0.2–5.0; 2/141) and 1.4% (95% CI: 0.6–2.7; 8/576). Prevalence increased with inconsistent facemask-use in school, walking to school, and case-contacts outside school. For three of nine households with infection(s), origin in school seemed possible. After 1 week, no school-related secondary infections appeared in affected classes; the attack rate in connected households was 1.1%.

Conclusion

School attendance under rigorously implemented preventive measures seems reasonable. Balancing risks and benefits of school closures need to consider possible spill-over infection into households. Deeper insight is required into the infection risks due to being a schoolchild vs attending school.
The role of unsaturated soil mechanics in unconventional tailings deposition
Authors: Simms Paul
Published: August 2021

Desiccation (water loss by drying or freeze-thaw sufficient to generate matric suction), can influence the performance of a tailings deposit both positively and negatively. The significance of desiccation is largest in tailings that have been dewatered prior to deposition, by thickening or filtration. Such tailings can be “stacked” or deposited with a significant slope, which usually implies that a substantial volume of tailings remain above water. Under such conditions the tailings, by accident or by design, may undergo desiccation before burial by fresh tailings. Desiccation can contribute substantially to strength, above and beyond the contribution arising from increase in density, through stress history effects. For some deposits, it is required practice that at least some tailings undergo desiccation to improve, particularly when those tailings for a structural part of a deposit. If, however, tailings remain exposed to the atmosphere in an unsaturated state for some period of time, this may have potential negative consequences through oxidation of sulphide minerals and the formation of acid drainage. This paper describes previous research on the strength gained through desiccation in tailings, and on modelling work that incorporates unsaturated soil phenomena into consolidation analysis. Both types of research are applied to a real field site, providing an example of how novel improvements to tailings management can arise out of application of principles of unsaturated soil mechanics.
Eş‛arîliğin Şam Bölgesinde Yayılma Süreci
Authors: YAVUZ Abdullah Ömer
Published: August 2021

Tarihsel süreçte İslam düşünce ekolleri tek tip bir bütüncüllüğe sahip değillerdir. Bundan dolayı mezhepler mekân ve zamanın değişmesi, muhataplık ilişkileri gibi çeşitli etkenlere bağlı olarak farklılaşmalar gösterebilirler. Sünnîliğin ana mezheplerinden birisi olan Eş‛arîlik, Irak coğrafyasında ortaya çıktı. Farklı bölgelere yayılan Eş‛arîliğin Şam coğrafyasında nasıl ve ne şekilde tezahür ettiği bu araştırmanın ana problemini oluşturmaktadır. İlk olarak İmam Eş‛arî ve Bâkıllânî’nin öğrencileri vasıtasıyla bölgeye intikal eden mezhep Gazzâlî’nin Dımaşk’a gelmesi ile güçlendi. Bölgede Şâfiîlik zemininde nüvelenen Eş‛arîliğin muhatapları arasında Hanbelîler de yer almaktadır. Selçuklular ile başlayan Sünnîlik merkezli siyaset anlayışı Şam coğrafyasına etki etti. Zengîler ve Eyyûbîler’in Selçuklu mirasına sahip çıktılar. Hem Nureddîn Mahmûd Zengî hem de Selâhaddîn-i Eyyûbî bu sürecin önemli aktörleri olarak karşımıza çıkmaktadır. Nitekim bu politikaların sonucunda Sünnî mezheplere alan açan medreseler kuruldu. Kurulan medreselerin Nizâmiye etkisinde kaldığını söylemek mümkündür. Bununla birlikte Eş‛arîliğin bu medreseler vasıtasıyla güçlendiği anlaşılmaktadır. Ayrıca Sünnîliğin güçlenmesi ile Şam bölgesinde Şiîliğin izleri de silinmeye başlandı. Eş‛arîlik ise Hadis taraftarlığının etkisi ile şekillendi. Aynı zamanda felsefeye yönelik sert tutumların ortaya çıkması Eş‛arî düşüncenin daha da sınırlı kalmasına yol açtı. Dolayısıyla Eş‛arîlik hem bölgedeki düşünce atmosferinden etkilendi hem de siyasi otoritelerin çizdiği Sünnî üst kimliğinin bir parçası oldu. Araştırmamızda sosyal tarihçiliğin yöntemlerinden faydalanıldığı gibi süreç takibi yapıldı.

Research has been carried out on a mobile-based presence system authentication method using MAC addresses, BSSID and IP addresses for (Wi-Fi) networks. This study aims to develop an authentication method on the attendance system that meets two authentication requirements, namely the suitability of employee identity and location suitability, so that the attendance process becomes easy, effective, fast, and can reduce fraud. The employee's identity can be obtained from the MAC address of the smartphone that has been previously registered, while the employee's location during the attendance process can be confirmed to be in the company environment by checking the BSSID data and IP of the Wi-Fi network connected to the smartphone. The data is then compared with MAC address data from all Wi-Fi networks installed in the company area. RAD is used as a development model because it is simple and fast. Overall, employee identification and site checking as authentication of the developed system went well.  Other than that, every function on the system works well. Furthermore, the results of the user experience evaluation using the UEQ questionnaire received an average score above 0.8 on 6 scales. This shows that the system has attractiveness, perspicuity, efficiency, dependability, stimulation and novelty.
