Authors: Dilsiz Abdullah , Özuygur Ali Ruzi
Published: December 2024

Bir yapı konumunda, taban kayasına ulaşan sismik dalgalar, üstündeki zemin aracılığıyla temele doğru yayılır ve dalganın bir kısmı temel ara yüzünden zemine geri yansırken, diğer bir kısmı ise yapıya iletilir ve yapının tepesinden tekrar zemine yansır. Bu süreç hem zeminin ve hem de yapının dinamik davranış özellikleri ile de etkileşim içerisindedir. Bu olayın tamamına Zemin-Yapı Etkileşimi (ZYE) denilmektedir. ZYE hakkında çok sayıda akademik araştırma mevcuttur. Türkiye Bina Deprem Yönetmeliği (TBDY) kazıklı temellerinin ZYE ile deprem etkisi altında gerçekleştirilen analiziyle ilgili ayrıntılı hükümler içermektedir. TBDY tarafından benimsenen en basit yöntemde, kazıklar çubuk elemanlar olarak modellenir; çubuk elemanların düğüm noktalarına zeminin yatay ve düşey basınçlarını temsilen doğrusal olmayan yatay ve düşey yaylar tanımlanır; ayrıca kazığın alt ucuna zeminin düşey basıncını temsilen doğrusal olmayan düşey yay tanımlanır. Zeminin yatay, düşey ve kazık uç direnci için basınç-yerdeğiştirme ilişkisi sırasıyla p-y, t-z ve Q-z ile gösterilir. Bu çalışmada, kazıklı temele sahip bir rüzgâr türbininin dinamik davranışı, i) yukarıda açıklanan doğrusal olmayan zemin yaylarının dikkate alındığı ve ii) temelin ankastre mesnet kabul edildiği durumlar için incelenmiştir. Bu iki durum için ayrıca yatay yerdeğiştirmenin esas alındığı kırılganlık eğrileri elde edilmiştir. Yapılan sayısal analizler sonucunda rüzgâr türbini kulesi iç kuvvet istemlerinde önemli sayılabilecek farklılıkların oluştuğu, ancak kulenin yatay yerdeğiştirme istemindeki farkın ihmal edilebilir mertebede olduğu görülmüştür.

Возрастная макулярная дегенерация (ВМД) и глаукома являются наиболее распространенными заболеваниями пожилого возраста и причиной необратимой слепоты в развитых странах. Болезнь Альцгеймера (БА), наиболее распространенная причина деменции у пожилых людей, часто ассоциирована с ВМД и глаукомой. К особенностям БА относят внеклеточное накопление β-амилоида (Аβ) и внутриклеточные отложения гиперфосфорилированных форм тау-белка. Помимо этого, в патогенез БА вовлечены нейровоспаление и нарушение обмена железа в головном мозге, что, в конечном итоге, приводит к прогрессирующей гибели нейронов и деменции. Было обнаружено, что в сетчатке пациентов с ВМД также происходит накопление Aβ и железа. В ганглиозных клетках сетчатки, поражающихся при глаукоме, аккумулируются Aβ и p-tau. В конечном счете, сопутствующее воспаление усугубляет патологический процесс. У пациентов с БА происходит выраженное снижение зрительных функций, и предполагается, что оно развивается до снижения когнитивных функций. Некоторые из них вызваны дегенерацией зрительной коры, другие — потерей ганглиозных клеток сетчатки или дегенерацией сетчатки, связанной с ВМД.

In developed countries age-related macular degeneration (AMD) and glaucoma are the most common diseases of old age that cause irreversible blindness. Alzheimer’s disease (AD), the most prevalent cause of dementia among older adults, is often associated with AMD and glaucoma. Features of AD include extracellular accumulation of β-amyloid (Aβ) and intracellular deposits of hyperphosphorylated forms of tau-protein. In addition, neuroinflammation and impaired iron metabolism in the brain are involved in the pathogenesis of AD, which ultimately leads to progressive neuronal death and dementia. It was found that the retina of patients with AMD also accumulates Aβ and iron, as well as Aβ and p-tau in retinal ganglion cells affected by glaucoma, and concomitant inflammation aggravates the pathological process. Patients with AD experience a marked decline in visual function which is thought to develop before the decline in cognitive function. Some are caused by degeneration of the visual cortex, others by retinal ganglion cell loss or retinal degeneration associated with AMD.

The integration of AI-powered automation in web crawling marks a significant advancement over traditional methods, which were often labor-intensive, inflexible, and prone to security risks. This paper presents a case study on the implementation of a dynamic web crawling solution using Azure Automation Account, leveraging GPT-3.5 from Azure OpenAI services. This new approach allows for parameterized execution via automation variables, enabling user-defined requirements to guide the crawler's behavior in a more flexible and intelligent manner. Unlike previous static methods that required constant manual adjustments, our system uses GPT-3.5's Natural Language Processing (NLP) capabilities to interpret complex instructions and dynamically adapt to various web structures. Post-crawling, the data undergoes a security scan using Clam AV, ensuring its integrity before storage in Azure Blob Storage. SendGrid is employed for user alerts regarding the scan results and storage status. The system is scheduled to run at regular intervals, fully automating the process while maintaining robust security protocols. This paper includes a detailed comparison between traditional web crawling techniques and this AI-driven approach, demonstrating the improvements in efficiency, security, and adaptability.

This paper presents the hierarchical sliding mode control (HSMC)--based stabilization problem of the wheeled Acrobot (WAcrobot) system, which combines an actuated wheel that rolls in the horizontal plane with an Acrobot consisting of two inverted pendulum links. These links are driven by an actuator at the second joint and freely rotate in a vertical plane. The stabilization problem of the WAcrobot, previously addressed using switch-based controllers in many studies, is solved in this work by designing a single-stage controller without requiring switching steps or time. The design approach comprises two parts. First, the system is reduced to a cascaded nonlinear model in finite time using the inherent dynamic coupling relationship. Second, a two-loop control scheme is employed: the outer loop ensures that the actuated state variables track the desired response, while the inner loop forces them to exhibit an asymptotically stable nature. After the desired design of both loops, the asymptotic stability of the overall dynamics is achieved. Finally, the theoretical analysis is validated using MATLAB. Simulation results demonstrate that the proposed controller effectively stabilizes the WAcrobot system at the equilibrium points.

Published: December 2024

Braking systems are an integral component of both passenger cars and commercial vehicles. Braking lag or delay endangers both the driver and the vehicle, as well as the effectiveness of the brakes. This becomes riskier as the hill begins to rise. To give the driver the chance to run safely when the brakes are applied, the Hill Start Assist is combined with the standard ABS. This can help avoid rollback on an incline. The characteristics that could help enhance this and increase braking efficiency will be the focus of the study. In this research , we design and compute the ideal brake force needed at different angles, and then create a MATLAB model to simulate the outcomes. This would help to make the system more efficient, prevent energy loss, and reduce the dependency on the footbrake valve.

Institutions and Economic Growth: A Panel Granger Causality Analysis
Authors: Ouahhabi Ouiem , Zouiri Lahboub
Published: December 2024

This paper revisits the direction of causality between institutions and economic growth for a sample of 119 countries over the period 1999-2018, divided into four groups according to income level: high income, upper middle income, lower middle income and low income. The study uses two institutional datasets, the International Country Risk Guide (ICRG) for the main estimation and the World Governance Indicators (WGI) for check the robustness of the results. Using the non-causality Granger test in a heterogeneous panel model with fixed coefficients, developed by Dumitrescu and Hurlin (2012), the empirical results show a unidirectional relationship for all panels except for lower middle-income countries, where causality is bidirectional. The findings also suggest that causality patterns are heterogeneous and depend on the level of development of the countries. Based on these results, we propose some interesting recommendations. The types of reforms to prioritize must be determined according to the direction of causality between institutions and economic growth. Moreover, heterogeneous causality implies the implementation of different policies adapted to the level of development of each panel, rather than considering a common policy.

Based on statistical measures of food consumption in 2022, the annual quantity of cassava waste amounts to 578 tons. Beyond its usage as animal feed, cassava skin has further potential as an active carbon source for absorbing heavy metals. This is because cassava skin contains carbon (59.31%), cellulose (13.75%), and lignin (9.14%), which may serve as precursors in the production of activated carbon. The objective of this work is to identify the optimal use of cassava skin waste. This study used a laboratory-based approach, beginning with the production of activated carbon from cassava peel and then applying it to synthetic materials on a laboratory scale. A cassava peel activated carbon produced using an H3PO4 activator has been determined to satisfy the requirements specified in the SNI 06-3730-1995 standard. The activated carbon has a water content of 0.65%, an ash content of 0.85%, a pure carbon content of 98.72%, and an iodine absorption capacity of 809 mg/g. Based on the findings of this experiment, it can be inferred that including a processing unit prior to the aforementioned stage, such as flash mixing and sedimentation, is necessary to optimize the efficiency of activated carbon technology. Based on the test result, 2.5 gr of activated carbon added to 700 ml of sample was continued with the addition of PAC 30 mg/l. Able to reduce turbidity level with a removal efficiency of up to 89.9%, iron of 43%, and ammonia at 17% these results are better than the use of PAC without activated carbon. The adsorption isotherm model represents the adsorption of iron and ammonia is Freundlich while turbidity is Langmuir.

Penelitian ini bertujuan untuk mengevaluasi pengaruh tekanan anggaran waktu, kompetensi, independensi, dan integritas terhadap kualitas audit, dengan mempertimbangkan etika auditor sebagai variabel moderating. Penelitian ini menggunakan metode kuantitatif dengan pengumpulan data melalui kuesioner yang diisi oleh auditor dari berbagai kantor akuntan publik. Analisis data dilakukan menggunakan teknik regresi dengan bantuan perangkat lunak statistik. Hasil penelitian menunjukkan bahwa terdapat pengaruh signifikan tekanan anggaran waktu terhadap kualitas audit, dengan nilai P sebesar 0,035 (< 0,05). Kompetensi juga ditemukan memiliki pengaruh signifikan terhadap kualitas audit, dengan nilai P sebesar 0,003 (< 0,05). Selain itu, independensi dan integritas masing-masing memiliki pengaruh signifikan terhadap kualitas audit, dengan nilai P masing-masing sebesar 0,045 dan 0,000 (keduanya < 0,05). Namun, hasil penelitian menunjukkan bahwa etika auditor tidak memoderasi pengaruh tekanan anggaran waktu terhadap kualitas audit, dengan nilai P sebesar 0,477 (> 0,05). Sebaliknya, etika auditor memoderasi pengaruh kompetensi terhadap kualitas audit, dengan nilai P sebesar 0,026 (< 0,05). Etika auditor tidak memoderasi pengaruh independensi terhadap kualitas audit, dengan nilai P sebesar 0,379 (> 0,05). Demikian pula, etika auditor tidak memoderasi pengaruh integritas terhadap kualitas audit, dengan nilai P sebesar 0,323 (> 0,05). Temuan ini mengindikasikan bahwa tekanan anggaran waktu, kompetensi, independensi, dan integritas secara individu berpengaruh signifikan terhadap kualitas audit, peran etika auditor sebagai variabel moderating tidak selalu memperkuat hubungan tersebut. Secara khusus, etika auditor hanya memperkuat pengaruh kompetensi terhadap kualitas audit, tetapi tidak memperkuat pengaruh tekanan anggaran waktu, independensi, dan integritas terhadap kualitas audit. Penelitian ini memberikan wawasan penting bagi manajemen kantor akuntan publik untuk memfokuskan pada pengembangan kompetensi auditor dan memastikan penerapan etika yang fleksibel untuk mendukung kualitas audit yang tinggi.

Published: December 2024

Penelitian ini bertujuan untuk menganalisis pola kepemimpinan blusukan dalam perspektif hadis, dengan menyoroti relevansi historisnya dan penerapannya dalam konteks sosial-politik di Indonesia. Blusukan, yang merujuk pada praktik pemimpin terjun langsung ke masyarakat untuk memahami kebutuhan mereka, telah menjadi fenomena menarik dalam politik modern. Artikel ini berupaya menggali pemahaman tentang blusukan dengan metode ma’anil hadis, yaitu pendekatan untuk memahami makna hadis dalam konteks sosial dan historis. Hasil penelitian menunjukkan bahwa blusukan sejalan dengan prinsip kepemimpinan yang dicontohkan oleh Rasulullah SAW dan para sahabat, yang menekankan interaksi langsung dengan masyarakat untuk memahami dan menyelesaikan permasalahan mereka. Praktik ini tidak hanya memiliki dampak positif, seperti meningkatkan kepercayaan masyarakat dan menghasilkan kebijakan yang lebih efektif, tetapi juga menghadapi kritik, terutama jika dipersepsikan sebagai alat politik. Faktor budaya dan sosial memainkan peran penting dalam menentukan efektivitas blusukan sebagai pola kepemimpinan. Kesimpulan penelitian ini adalah bahwa blusukan dapat menjadi pola kepemimpinan yang tidak hanya efektif secara politik tetapi juga relevan secara sosial, jika dilakukan dengan niat tulus untuk melayani masyarakat. Implikasi dari penelitian ini adalah perlunya penerapan blusukan yang didasarkan pada nilai-nilai etis dan ajaran Islam, sehingga dapat memperkuat hubungan antara pemimpin dan masyarakat serta memberikan kontribusi positif terhadap dinamika sosial-politik di Indonesia.

Goal. To assess the effect of various organic fertilizers on the yield of hazelnut plantations in the conditions of the Southern Steppe of Ukraine.
Methods. Field experiment, laboratory-analytical, comparative.
Results. The influence of organic fertilizers of various origins was studied (cattle manure; chicken droppings; Biofertilizer No. 1 — sewage sludge (SW) of the biological treatment station (SBO) «Pivdenna» in Odesa + winter wheat straw + Microbacterium barkeri LP-1 (M. b.); Biofertilizer No. 2 — «Southern» SBO + sunflower seed husks + M. b.; «Pivdenna» SBO, Odesa) on the agrochemical parameters of ordinary medium-humus chernozem in the conditions of the Southern Steppe of Ukraine for the cultivation of hazelnuts. It is shown that in comparison with the control of 2021 and 2022, an increase in the content of easily hydrolyzed nitrogen, mobile forms of phosphorus and potassium, and organic matter is noted in all variants of the experiment.
Conclusions. The use of organic fertilizers of various origins for the cultivation of hazelnuts in the conditions of the Southern Steppe of Ukraine helps to increase the content of the main agrochemical indicators of the soil — easily hydrolyzed nitrogen (91.0—98.0 mg/kg with 84.0 mg/kg — control), mobile phosphorus compounds (174.75—306.30 mg/kg at 138.75 mg/kg — control), potassium (112.00—166.90 mg/kg at 108.40 mg/kg — control) and organic matter (3.78—4.18% and 3.76% — control). The advantages of biofertilizers No. 1 and No. 2 based on sewage sludge with the use of vegetable fillers (winter wheat straw and sunflower seed husks) and the phosphate-mobilizing bacterium Microbacterium barkeri LP-1 are shown. Organic fertilizers contribute to the increase in the content of nutrients in the soil, the activation of the activity of eco-trophic groups of microorganisms, which leads to an increase in the biological activity of the soil and, accordingly, the yield of agricultural crops.
77 years of uninterrupted agricultural research in Suceava

Published: December 2024

In 1946, by decision no. 1933 of the Ministry of Agriculture, the first agricultural research unit in the northern part of Moldova (the Suceava Experimental Agricultural Station, currently the Suceava Agricultural Research and Development Station) was established, as a necessity for the development of agriculture in Bucovina. After three years of operation in the submontane area from Ilisesti (19 km from Suceava), by decision no. 564249 of August 24 of the same ministry, the resort was transferred to Suceava. The area where the cantonment is located is individualized by specific pedoclimatic conditions, characterized by thermal restrictions, the non-uniformity of the hydrological regime — from insufficient to excessive — and by a great diversity of soil types, from soils with low fertility to those with good fertility. The consequence of this ecological diversity was, from the beginning, the need to diversify the concern related to research activity in response to solving the main problems of agriculture in the Suceava Plateau. If in the year of establishment (1946) the concerns were directed towards the cultivation of potatoes, meadows and fodder plants, over time it can be seen by following the evolution of concerns and the way of achieving the basic objectives of agricultural research, in Suceava, a continuous expansion of the problem areas addressed as well as the amplification of their complexity.
