ASÂKİR-İ MANSÛRE-İ MUHAMMEDİYYE’NİN İSYAN BASTIRMA FAALİYETLERİNDE KULLANIMI: ARNAVUTLUK’UN İTAAT ALTINA ALINMASI
Authors: Turan Ahmet
Published: May 2024

Sultan II. Mahmud’un mülki idarede merkezileşme politikası çoğu zaman, hem İstanbul’un otoritesinin uzanmadığı yerlerde yaşayan yerel halk hem de merkezden bağımsız hareket eden mahalli güç sahipleri tarafından mukavemet ile karşılanmıştır. Bu mukavemetin sebeplerinden biri de, kaldırılan Yeniçeri Ocağı yerine kurulan düzenli orduya duyulan nefer ihtiyacının, zorunlu askerlik hizmeti ile giderilmeye çalışılmasıdır. Çalışmamızın ana eksenini, merkezi idarenin bu mukavemet yerlerinden biri olan Arnavutluk’ta, düzeni sağlamaya yönelik askeri faaliyetleri oluşturmaktadır.
Çalışmamızda Arnavutluk’un güneyinden başlayarak kuzeyine yönelen askeri harekâtın ne şekilde icra edildiği ve düzenli ordu birliklerinin isyan bastırma faaliyetlerinde kullanımının bir tercih mi zorunluluk mu olduğu sorusu ele alınıp cevaplanmaya çalışılmıştır. Osmanlı düzenli ordu birliklerinin bir iç kolonizasyon enstrümanı olarak, devletin son dönemine kadar kullanılmasının tarihsel arka planı, arşiv belgeleri ile desteklenilerek açıklanmaya gayret edilmiştir.
RUMELİ’DE BİR EŞKIYA: HİBETULLAH “ZÎDE KADRUHÛ”
Authors: Akşit Bekir
Published: May 2024

Bu makale, 18. yüzyıl başlarında Manastır ve çevre kazalarda etkili olan eşkıya Hibetullah’a odaklanmaktadır. Makalenin temel amacı, Hibetullah'ın kimliğini tespit etmek, faaliyetlerini incelemek ve bu eşkıyanın zaman içinde nasıl algılandığını anlamaktır. Öncelikle Türkiye ve Balkanlarda eşkıyalık literatürüne ait birkaç örnek verilmiştir. Hibetullah’ın kimliği tespit edildikten sonra literatürdeki eşkıya algısının farkına değinilmiştir. Arşiv kaynakları, Hibetullah'ın faaliyetleri ve devlet tarafından nasıl görüldüğü konularında temel bilgiler sağlamak üzere kullanılmıştır. Ayrıca, makalede öne sürülen iddiaya göre, eşkıyanın merkezileşme için bir araç olarak kullanıldığı vaka üzerinden değerlendirilmiştir. Bölgesinde namlı bir eşkıya olan Hibetullah’ın aynı zamanda martolos olması, bu askeri grup ile eşkıyalar arasındaki bağı göstermek açısından da önemlidir. Lanetlenen bir eşkıyanın zaman ve mekânın şartlarına göre dua alan bir askere nasıl dönüşebileceği üzerinde durulmuştur. Hibetullah'ın ölümü, bölgedeki eşkıyalık hareketlerine son vermemiştir. İddia edildiği gibi eşkıyalık merkezileşmenin bir aracı olmaktan ziyade, eşkıyalık ile mücadele edilerek mevcut düzen korunmak istenmektedir. Eşkıyaların bağışlanarak sisteme dahil edilmesi martolosların eşkıyalarla daha derin bağlar kurmasına ve bu grubun yozlaşmasına yol açmıştır.

Aim: Diffuse large B-cell lymphoma (DLBCL) is the most common B-cell non-Hodgkin lymphoma (NHL). Despite the availability of clinical and molecular algorithms applied for the prediction of prognosis, in up to 30%-40% of patients, intrinsic or acquired drug resistance occurs. Constitutional genetics may help to predict R-CHOP resistance. This study aimed to validate previously identified single nucleotide polymorphisms (SNPs) in the literature as potential predictors of R-CHOP resistance in DLBCL patients, SNPs.

Methods: Twenty SNPs, involved in R-CHOP pharmacokinetics/pharmacodynamics or other pathobiological processes, were investigated in 185 stage I-IV DLBCL patients included in a multi-institution pharmacogenetic study to validate their previously identified correlations with resistance to R-CHOP.

Results: Correlations between rs2010963 (VEGFA gene) and sex (P = 0.046), and rs1625895 (TP53 gene) and stage (P = 0.003) were shown. After multivariate analyses, a concordant effect (i.e., increased risk of disease progression and death) was observed for rs1883112 (NCF4 gene) and rs1800871 (IL10 gene). When patients were grouped according to the revised International Prognostic Index (R-IPI), both these SNPs further discriminated progression-free survival (PFS) and overall survival (OS) of the R-IPI-1-2 subgroup. Overall, patients harboring the rare allele showed shorter PFS and OS compared with wild-type patients.

Conclusions: Two out of the 20 study SNPs were validated. Thus, these results support the role of previously identified rs1883112 and rs1800871 in predicting DLBCL resistance to R-CHOP and highlight their ability to further discriminate the prognosis of R-IPI-1-2 patients. These data point to the need to also focus on host genetics for a more comprehensive assessment of DLBCL patient outcomes in future prospective trials.
G protein-coupled receptors: a gateway to targeting oncogenic EVs?

Published: May 2024

Dysregulated intercellular communication is a key feature driving cancer progression. Recently, extracellular vesicles (EVs) have added a new channel to this dense communication network. Despite solid evidence that EVs are central mediators of dysregulated signaling in onco-pathological settings, this has yet to be translated into clinically actionable strategies. The heterogeneity of EV cargo molecules, plasticity of biogenesis routes, and large overlap with their role in physiological communication, complicate a potential targeting strategy. However, recent work has linked EV biology to perhaps the "most druggable" proteins - G protein-coupled receptors (GPCRs). GPCR targeting accounts for ~60% of drugs in development and more than a third of all currently approved drugs, spanning almost all areas of medicine. Although several GPCRs have been linked to cancer initiation and progression, relatively few agents have made it into oncological regimes, suggesting that their potential is underexploited. Herein, we examine the molecular mechanisms linking GPCRs to EV communication in cancer settings. We propose that GPCRs hold potential in the search for EV-targeting in oncology.

Published: May 2024

Patient information and medical imaging data are now subject to stringent data security and confidentiality standards due to the proliferation of telemedicine techniques and medical imaging instruments. Because of the problems described above, as well as the possibility of data or information being stolen, this brings up the dilemma of transmitting data on medical images via an open network. In the past, potential solutions included the utilization of methods such as information concealment and image encryption. Nevertheless, attempting to reconstruct the original image utilizing these approaches may result in complications. In the process of this paper, an algorithm for safeguarding medical images based on the pixels of interest was established. Detection of image histogram peaks for the purpose of calculating peaks in medical images pixels of interest in medical image that have had their threshold values processed. The threshold is shown by taking the average of all the peaks in the histogram. After that, a Sudoku matrix is used to assign values of interest to each of these pixels. The proposed method will be assessed by a variety of statistical procedures, and the outcomes of these analyses will be compared to previously established standards. According to the findings, the suggested method has superior security performance compared to other image encryption methods already in use.

Published: May 2024

The paper considers the problem of short- and middle-term forecasting in the financial sphere. To solve this problem, a hybrid system of computational intelligence based on the group method of data handling (GMDH) and bagging, as well as an algorithm for its training, is proposed. The odd stacks of the hybrid system are formed by ensembles of parallel connected subsystems. ARIMA and the GMDH-neo-fuzzy hybrid network were chosen as such subsystems. The proposed system does not require a large training data set, automatically determines the number of stacks during training, and provides online operation. The experimental investigations were conducted using the proposed hybrid system, as well as separately using ARIMA and GMDH-neo-fuzzy. The accuracy of the predictions obtained is compared, based on which the feasibility of using the proposed hybrid system is substantiated.

The article discusses the various methods of estimating the surface cathode temperature of the high-voltage glow discharge electron gun, which forms a ribbon electron beam with a linear focus. Numerical estimations have been made to design the cathode assembly of an industrial gun. It is shown that the most effective way to make approximate estimates of the temperature of the cathode surface in high-voltage glow discharge electron guns for various technological purposes is to use arithmetic-logical ratios for modeling the geometry of the cathode assembly and locus functions for estimating the temperature distribution. The accuracy of such estimates, made using the heat balance equation, was 5–10%, sufficient at the initial stage of designing an electron gun. It is shown that using the SolidWorks CAD software complex for designing high-voltage glow discharge electron guns is effective only for solving the complex engineering design tasks and preparing the corresponding technical documentation. The results of the theoretical research published in the article are of interest to a wide range of specialists engaged in developing electron beam equipment and its implementation in industrial production.
Ciudades al límite: la sostenibilidad urbana en el paradigma del crecimiento y la escasez = Cities on the Edge: Urban sustainability in the paradigm of growth and scarcity
Authors: De Juan Ayuso Ibai
Published: May 2024

ResumenFrente a un contexto ambiental caracterizado por la triple crisis de recursos naturales, cambio climático y pérdida de biodiversidad, el decrecimiento emerge como alternativa al modelo de desarrollo hegemónico. Sin embargo, la propuesta del decrecimiento requiere una mayor profundización con especial atención al medio urbano. El presente trabajo aproxima las contingencias y contradicciones que el decrecimiento puede encontrar en el descenso de la teoría a la práctica y su adecuación al marco estratégico de sostenibilidad urbana asociado con la Agenda Urbana Española. Se observa que el incipiente debate en torno al decrecimiento urbano permite especificar en un mayor grado la propuesta del decrecimiento. A su vez, revela cierta ambigüedad en relación con las líneas estratégicas de la AUE dado que ambos tienen objetivos similares, pero posicionamientos dispares. El decrecimiento aboga por un cambio estructural respecto a las dinámicas de acumulación que acontecen sobre el territorio, al tiempo que la AUE aúna sostenibilidad y crecimiento económico alimentando así una serie de contradicciones que agudizan la problemática de la insostenibilidad urbana.AbstractIn an environmental context characterised by the triple crisis of natural resources, climate change and biodiversity loss, degrowth emerges as an alternative to the hegemonic development model. However, the degrowth proposal requires further attention especially in the urban context. This paper approaches the contingencies and contradictions that degrowth may encounter in the descent from theory to practice and its adaptation to the strategic framework of urban sustainability associated with the Spanish Urban Agenda (AUE). It is observed that the incipient debate around urban degrowth allows the degrowth proposal to be specified to a greater degree. At the same time, it reveals a certain ambiguity in relation to the strategic lines of the AUE, given that both have similar objectives, but different views. Degrowth advocates for a structural change in relation to the dynamics of accumulation that take place in the erritory, while the AUE combines sustainability and economic growth, thus feeding the contradictions that exacerbate the problem of urban unsustainability.

Authors: Hasanudin Fuat , Yuke Yolanda  , Muhammad Zahrie Nurhadiansyah
Published: May 2024

Berdasarkan data dari Asosiasi Pencegahan Bunuh Diri Indonesia, faktor utama yang menyebabkan terjadinya kasus bunuh diri adalah keluarga. Mereka terdorong untuk bunuh diri karena masalah yang dihadapi dengan keluarga mereka sendiri. Dalam banyak kasus di Indonesia, keluarga korban yang bunuh diri sering kali menjadi bahan cemoohan. Korban dianggap sebagai manusia yang gila, kurang iman, bahkan disebut sebagai orang kafir. Adapun keluarga korban bunuh diri sering kali menganggap bunuh diri sebagai hal tabu yang menjadi suatu aib. Sedangkan dalam realitanya, percobaan bunuh diri adalah fenomena umum di banyak belahan dunia. Upaya bunuh diri erat kaitannya dengan aspek psikologis dan pengambilan keputusan. Berdasarkan hal tersebut, penelitian ini menganalisa perbandingan perspektif antara Sivitas AkademikaPsikologi dan Hukum Islam di Yogyakarta terhadap kasus bunuh diri. Desain penelitian adalah kualitatif melalui pengisian formulir dan wawancara secara mendalam menggunakan pertanyaan terbuka untuk mendapatkan informasi yang dibutuhkan. Hasil dari penelitian ini menunjukkan bahwa terdapat beragam pandangan dari Para Sivitas AkademikaUniversitas di Yogyakarta. Gangguan mental yang terjadi pada setiap orang memiliki tingkatan yang berbeda- beda. Gangguan mental dengan dorongon untuk bunuh diri bukanlah suatu aib yang harus ditutupi, tetapi hendaknya dicari penyelesaian terbaik. Faktor keluarga yang mendominasi pengaruh seseorang untuk bunuh diri, disisi lain keluarga juga menjadi support system yang dapat mencegah seseorang untuk melakukan bunuh diri. Peran agama dalam pencegahan gangguan mental dan kecenderungan untuk bunuh diri menjadi faktor penting lainnya. Pendekatan yang dilakukan tidak hanya agama dilihat dari segi hukum melaikan juga dengan penekanan pada keberagamaan (religiositas). Penanaman ini juga dapat menggunakan beragam metode yang sesuai dengan penyandang gangguan kesehatan mental, tidak melalui ceramah ancaman, tetapi lebih kepada dorongan dan motivasi akan kebaikan dan kebahagiaan yang diajarkan oleh agama.

Published: May 2024

Penelitian ini menggali peran ayah dalam pengasuhan anak di konteks pendidikan Islam, dengan fokus pada guru-guru laki-laki di Pondok Pesantren Nurul Arofah Nahdatul Wathan. Seringkali literatur pengasuhan mengabaikan peran ayah, namun studi ini menyoroti pentingnya keterlibatan ayah, baik dalam kehidupan keluarga maupun dalam profesi keguruan. Dengan pendekatan kualitatif dan teknik purposive sampling, penelitian ini mengidentifikasi lima peran ayah: penyedia nafkah, pelindung, pengambil keputusan, pendidik khusus anak, dan pengasuh. Hasil penelitian ini menunjukkan bahwa ayah-guru telah mampu memenuhi peran-peran ini, dengan dua di antaranya mencapai tahap 'keluarga sakinah III' dan dua lainnya mencapai 'keluarga sakinah III plus', sebuah konsep dalam Islam yang merujuk pada keharmonisan keluarga. Temuan ini menegaskan bahwa dalam hukum Islam, pengasuhan anak adalah tanggung jawab bersama antara ayah dan ibu, di mana ayah memiliki peran krusial dalam memastikan pemenuhan kebutuhan dasar, pendidikan, perlindungan, dan pembinaan karakter anak-anak yang selaras dengan nilai-nilai Islam, etika, dan akhlak. Studi ini memberikan wawasan penting tentang dinamika keluarga Muslim dalam konteks pendidikan dan pengasuhan, serta menawarkan perspektif baru tentang keterlibatan ayah dalam membentuk keluarga sakinah.
This study delves into the role of fathers in child upbringing within the context of Islamic education, focusing on male teachers at the Nurul Arofah Nahdatul Wathan Islamic Boarding School. Often, parenting literature overlooks the father's role, but this study highlights the importance of paternal involvement, both in family life and in the teaching profession. Employing qualitative methods and purposive sampling techniques, the study identifies five roles of fathers: breadwinner, protector, decision-maker, children's educator, and caregiver. The findings indicate that teacher-fathers have been able to fulfill these roles, with two reaching the stage of 'sakinah family III' and another two achieving 'sakinah family III plus', a concept in Islam that refers to family harmony. These findings assert that in Islamic law, child upbringing is a shared responsibility between father and mother, where the father has a crucial role in ensuring the fulfillment of basic needs, education, protection, and character building of children in alignment with Islamic values, ethics, and morals. This study provides important insights into the dynamics of Muslim families in the context of education and upbringing and offers a new perspective on the father's involvement in forming a harmonious sakinah family.
Testing the Mechanistic-Universe Paradigm Using Chaotic Systems
Authors: Knoll Yehonatan
Published: May 2024

We humans are natural-born engineers. As such, we model after machines not only isolated, naturally occurring systems, but also the basic laws of physics, sharing with machines a local-evolution-of-state `grammar'. However, previous work by the author casts doubt upon this mechanistic paradigm, suggesting that it is to blame for the stubbornness of many open problems in physics. Simple experiments are therefore proposed to identify `non-machines'. In one experiment, `non mechanistic correlations' in the spirit of Bell are sought in a pair of separated but previously coupled (macroscopic) chaotic systems. In another it is tested whether chaotic systems could fuzzily `remember their future' in the sense that a future binary perturbation applied to them could be inferred from their present behavior with probability>1/2. Chaotic systems are chosen as candidates because the long-time application of their (deterministic) mechanistic description is conceptually groundless: All scales are significant and mutually coupled in that regime, down to scales governed by QM, yet the quantum-classical transition remains inexplicable---if only due to the measurement problem. Similarly for non-deterministic chaotic systems, modeled as such purely for defying a short-time deterministic mechanistic description. Should a non mechanistic signature be found in such simple systems, the implications for science as a whole and life sciences in particular cannot be overstated.

Published: May 2024

In this study, a new diphosphate compound, Ag0.2Na0.6FeP2O7, was synthesized using a solid-state reaction method and extensively studied using various techniques. The compound's structure was confirmed through X-ray diffraction analysis, revealing a single-phase monoclinic structure with the P21/C space group. The electrical behavior of the compound was investigated, and its conductivity followed Jonscher's universal law. The correlated barrier hopping (CBH) model explained the temperature-dependent ac conductivity and parameter "s" well. The study also explored the contribution of single-polaron and bipolaron hopping to the a.c. conductivity and discussed the ionic conductivity in relation to the structural characteristics of the sample. Overall, this investigation significantly enhances our comprehension of the distinctive electrical properties of Ag0.2Na0.6FeP2O7 and its potential practical applications.
Theoretical Study of the Impact of Pore Size in TiO₂ Aerogels on Photocatalytic Formaldehyde Decomposition
Authors: Sun Fenglei , Yu Xianbo , Xiang Junhui
Published: May 2024

Formaldehyde (HCHO), an indoor volatile organic compound, is seriously harmful to human health. Therefore, green and effective decomposition of HCHO is essential. TiO2 has been employed for the degradation of HCHO via photocatalytic generation of reactive oxygen species (ROS) (O2-, ·OH), yet the low specific surface area of crystalline TiO2 depressed the catalytic performance. Herein, we prepared TiO2 aerogels with high specific surface area and high porosity by sol-gel method, and added PVA to introduce flexible molecular chains for pore size regulation. The photocatalytic performance test verifies that the pore size of TiO2 aerogel is one of the important factors for HCHO decomposition. Notably, through the establishment of theoretical model and calculation, we validated that the efficiency of HCHO decomposition is related to the oxygen pressure in the pores of TiO2 aerogel, and the oxygen pressure is inversely proportional to the pore size. Accordingly, the optimal pore size of TiO2 aerogel for the photocatalytic HCHO decomposition is 2 nm-10 nm. This study provides a theoretical idea for TiO2 aerogels in the decomposition reaction of HCHO, which is expected to inspire more breakthroughs in the study of TiO2 aerogels for green chemistry.

Published: May 2024

Antimicrobial peptides (AMPs) are promising tools for combating microbial resistance. However, their therapeutic potential is hindered by two intrinsic drawbacks – low target affinity and poor in vivo stability. Macrocyclization, a process that improves the pharmacological properties and bioactivity of peptides, can address these limitations. As a result, macrocyclic peptides represent attractive drug candidates. Moreover, many drugs are macrocycles that originated from natural product scaffolds, suggesting that nature offers solutions to the challenges faced by AMPs. In this review, we explore natural cyclic peptides from the DBAASP database. DBAASP is a comprehensive repository of data on antimicrobial/cytotoxic activities and structures of peptides. We analyze the data on small (≤25 AA) ribosomal and non-ribosomal cyclic peptides from DBAASP according to their amino acid composition, bonds used for cyclization, targets they act on, and mechanisms of action. This analysis will enhance our understanding of the small cyclic peptides that nature has provided to defend living organisms.
Investigation of Flowback Behavior for Multi-Fractured Horizontal Wells in Gulong Shale Oil Reservoir Based on Numerical Simulation
Authors: Yu Shuxin , Wu Yucheng , Niu Langyu , Jia Pin
Published: May 2024

Multi-stage hydraulic fracturing with horizontal well technology has been widely used in shale oil reservoir. After hydraulic fracturing, hydraulic fractures and opened beddings are intertwined, which result in a complex fracture network. As well as the migration of multi-phase fluids during fracturing and soaking processes, which lead to complex flowback performance, and brings dif-ficulty to productivity evaluation and flowback strategies optimization. In this paper, taking the Daqing Gulong shale reservoir as an example, a numerical model for flowback period, which considered oil-water-gas three-phase flow and orthogonal fracture network has been established. The characteristics and influencing factors of flowback performance have been deeply studied, and the flowback modes of shale oil are reasonably optimized. Factors such as PTPG (pseu-do-threshold pressure gradient), opened bedding stress sensitivity, opened bedding permeability and matrix permeability have obvious effects on the flowback performance, resulting in signifi-cant variations in production peaks, high yield periods, and decline rates. In addition, three flowback modes are distinguished based on the rate at which the BHP (bottom hole pressure) drops. These correspond to three types of choke modes. Based on the result of numerical model, three flowback modes are optimized and the impacts of different flowback modes on shale oil flowback are clarified. This study is particularly important for understanding the performance of shale oil flowback and guiding the efficient exploitation of shale oil.

Kişinin içsel yolculuğunda derinleşen yetersizlik duygularına karşılık gelen mükemmeliyetçilik ve entelektüel sahtekârlık fenomeni başarının önündeki en büyük engeller arasındadır. Bu çalışmada, yükseköğretim kurumlarında görev yapmakta olan akademisyenlerden toplanan veriler üzerinden mükemmeliyetçi kişilik yapısının işyeri mutluluğu üzerindeki etkisinde entelektüel sahtekârlık fenomeninin rolü ortaya konulmuştur. Bu amaç doğrultusunda farklı anabilim dallarında uzmanlaşmış 433 akademisyene elektronik anket yöntemi aracılığıyla ulaşılmıştır. Elde edilen veriler SPSS ve AMOS programları kullanılarak analiz edilmiştir. Doğrulayıcı Faktör Analizinin (DFA) uygulanmasında ve hipotezlerin test edilmesinde Yapısal Eşitlik Modeli (YEM) kullanılmıştır. Araştırmanın sonuçlarına göre entelektüel sahtekârlık fenomeni mükemmeliyetçilikten pozitif yönde etkilenmekte, işyeri mutluluğunu ise negatif yönde etkilemektedir. Buna göre mükemmeliyetçi kişilik yapısına sahip olan akademisyenlerin entelektüel sahtekârlık fenomenini deneyimleme olasılıkları daha yüksektir ve bu durum da işyerindeki mutluluklarını azaltmaktadır. Ayrıca mükemmeliyetçiliğin alt boyutlarından olan tatminsizliğin işyeri mutluluğu üzerindeki etkisinde sahteliğin tam aracılık rolü olduğu tespit edilmiştir. Araştırma, kendi başarılarını içselleştiremeyen ve bir türlü kabul edemeyen yüksek başarılı kişilerde görülen entelektüel sahtekârlık fenomeni sürecini ortaya koyan bir model geliştirilmesi açısından önem arz etmektedir. Geliştirilen bu model kapsamında ele alınan üç değişkenin bir arada incelendiği başka çalışmaya rastlanılmaması bu araştırmanın alanyazına önemli katkılar sağlayacağını düşündürtmektedir.

Modern iş dünyası, farklı kişisel ve kültürel özellikler ile farklı algılamalara sahip çalışanlar ve yöneticilerden oluşmaktadır. Yöneticilerin kişilik tipilerinin müzakere stillerine etki ettiği düşünülmektedir. Bu çalışmada kamu sağlık kuruluşlarındaki yöneticilerin kişilik tipleri ile müzakere süreci arasındaki ilişkinin araştırılması amaçlanmıştır. Çalışma nitel araştırma yöntemlerinden gözlem ve derinlemesine görüşme yöntemiyle yürütülmüştür. Veriler Batı Anadolu Konya alt istatistik bölgesinde yer alan Konya ve Karaman illerinde kolayda örnekleme yoluyla ulaşılan kamu sağlık kuruluşlarında görev yapan 19 idarecilerinden elde edilmiştir. Araştırmada katılımcıların rızası ile 334 dakikalık ses kaydı verisi elde edilmiştir. Ses kayıtları kelime işlemci programına aktarılmış 9123 kelimelik görüşme metni oluşturulmuştur. Nitel yollarla elde edilen veriler MAXQUDA programı ile keşfedici bir yaklaşımla tematik olarak analiz edilmiştir. Analizde katılımcıların kişilik özellikleri ve müzakere yönelimleri iki vaka modeliyle kodlanmıştır. Katılımcılar yönetim, protokol kuralları, müzakere konularında eğitim almadıklarını bildirmişlerdir. Yöneticilerin mükemmeliyetçi melankolik ve güçlü klorik kişilik tiplerinin öne çıktığı harmonize kişilik tipine sahip olduğu görülmüştür. Ayrıca rekabetçi/işbirlikçi müzakere yöntemlerini birlikte kullandıkları görülmektedir. Müzakerelerde, kurumsal dinamiklerin kişilik özelliklerinden daha çok ön plana çıktığı dikkat çekmektedir. Müzakerelerde, mükemmeliyetçi melankolikler ile güçlü kloriklerin rekabetçi müzakere tarzına; barışçıl soğukkanlı ile popüler optimistlerin ise işbirlikçi müzakere tarzına daha yatkın olduğu belirlenmiştir.

This study presents an open-transmit and 24-channel flexible receiver head coil assembly tailored for high-resolution ultra-high field fMRI of the human somatosensory and motor cortex. Leveraging the increased signal-to-noise ratio (SNR) and spatial resolution of ultra-high field MRI, we address the technical challenges inherent in fMRI coil design. The open birdcage transmit coil enhances patient comfort and enables visual task implementation, demonstrating superior performance in transmit efficiency and SAR distribution compared to conventional coils. Furthermore, the 24-channel flexible receiver head coil offers enhanced SNR and image quality, facilitating sub-millimeter VASO imaging for precise functional mapping. These advancements provide valuable tools for unraveling the intricacies of somatosensory and motor cortex function. By enriching human brain functional studies, they contribute significantly to our understanding of the mechanisms underlying somatosensory and motor cortex function, with potential implications for clinical applications in neurology and neuroscience research.

Wolffia arrhiza is known as noxious weed and rated as one of the ten weeds growing country in South – East Asia, Commonly infesting natural impounded water in India. Studies have been made for their utilization in multiple ways in developing countries. Present study based on 24 hours pre-soaking seed treatment with control, 1,2 and 5% concentration of water extract of W. arrhiza for anatomical growth of stem of lentil plants variety DPL-15. The observation of stem show that the anatomical growth parameters like average diameter of stem, average thickness of stele, number of vascular bundles per microscopic field, average diameter of Xylem vessels, average diameter of Phloem is stimulated in seed treated with water extract for 24 hours. 5% level of water extract of W. arrhiza was found best for diameter of stem, number of vascular bundles per-microscopic field, and average thickness of stele. However for average diameter of Xylem vessels and average diameter of Phloem of lentil stem was observed better at 2% level of water extract of W. arrhiza. Results are statistically analyzed at 5% error probability.

The use of highly crosslinked ultra-high molecular weight polyethylene (UHMWPE) incorporating vitamin E (VE) as an antioxidant is widely acknowledged in the field of joint implants. While VE plays a crucial role in preventing oxidation, concerns have been raised regarding its impact on crosslink density, leading to wear performance deterioration. This study proposes the hypothesis that tea polyphenols, specifically lipid-soluble epigallocatechin gallate (IsEGCG) and epigallocatechin gallate (EGCG), may counteract the typical decrease in crosslink density caused by VE, thereby enhancing wear performance. The antioxidants were integrated into UHMWPE at a concentration of 0.2 wt%, followed by surface chemical crosslinking using di-cumyl peroxide. Surface properties, including crosslink density, roughness, coefficient of friction, and wear performance, were comprehensively evaluated. The results indicate a significantly higher crosslink density in UHMWPE blended with IsEGCG and EGCG compared to VE-stabilized UHMWPE, which exhibited a 17% reduction compared to virgin UHMWPE. The coefficient of friction increased post-crosslinking, with tea polyphenol-blended UHMWPE demonstrating a relatively higher value, confirming a highly crosslinked network structure. The wear resistance of surface-crosslinked UHMWPE stabilized with tea polyphenols was markedly superior compared to UHMWPE stabilized with VE. Additionally, a substantial presence of scratches, furrows, and flakes was observed on the surface of VE-stabilized UHMWPE in contrast to tea polyphenol-stabilized UHMWPE. These findings suggest that tea polyphenols present promising alternatives to VE for enhancing the overall performance and longevity of UHMWPE-based implants.

The current study aims to present a swarm-optimized technique for the numerical treatment of dengue fever non-linear model. The model is composed of the coupled nonlinear system comprising the susceptible, infected, and recovered compartments. The system is transformed into an unsupervised single layer feed-forward artificial neural network with a Mexican hat wavelet activation function in the hidden layer. The unknowns of the neural network is optimized with particle swarm optimization as an efficient global search aided by the effective local search technique based on sequential quadratic programming. The presented results are compared with state of art Runge-Kutta method and other modern reported techniques on various performance indicators like absolute error, mean average deviation, global absolute error, global mean average deviation, convergence, and computational complexity. Comprehensive Monte Carlo simulations and their statistical analysis are presented to ensure accuracy, consistency in convergence, and computational complexity in terms of execution time. It is observed that the proposed scheme is accurate, reliable, convergent, and computationally viable in treating the nonlinear coupled system under consideration.

Introduction:
Vitamin D and calcium in follicular fluid play essential roles in modulating steroidogenesis, folliculogenesis, and oocyte quality determination. Both collaborate to produce high-quality embryos (TQE) during in vitro fertilization. This study aimed to compare free 25(OH)D3 and calcium levels in follicular fluid between TQE and non-TQE groups (non-TQE).
Methods
This cross-sectional study included women who underwent IVF (In Vitro Fertilization) procedures at tertiary hospitals in Bandung, Indonesia. Ovarian follicular fluid was collected during the ovum pick-up procedure. Examination of 25(OH)D3 levels, vitamin D-binding protein and calcium in the follicles was performed using an enzyme-linked immunosorbent assay (ELISA). Free 25(OH)D3 levels were calculated using a method of Vermeulen formula.
Results
A total of 173 samples, consisting of 86 subjects in the TQE group and 87 subjects in the non-TQE group, met the study criteria. There was a significant difference in free 25(OH)D3 follicular fluid levels between the TQE and non-TQE groups (p = 0,017), there was no significant difference in calcium levels between the two groups (p = 0,805). This study also revealed that there was a significant association between free 25(OH)D3 follicular fluid level and embryo quality (OR 3.05, 95% CI, 1.46–6.38; p value = 0.002), but there was no significant association between follicular fluid calcium and embryo quality (p = 0.144 and OR, 1.74 (95% CI 0.82–3.68)).
Conclusion
These circumstances allow free 25(OH)D3 and calcium in the follicular fluid to act independently in the processes of steroidogenesis, folliculogenesis, and fertilization.
