Recall this Book 56: Merve Emre on Natalia Ginzburg's "The Dry Heart"
No full textLike our podcast, B-Side Books focuses on those moments when books topple off their shelves, open up, and start bellowing at you. The one that buttonholed Merve Emre (Oxford literature professor and author most recently of The Personality Brokers) was a novella by the luminous midcentury Italian pessimist, Natalia Ginzburg. And if you think you know precisely why a mid-century Italian writer would have a dark and bitter view of the world (already thinking of the Nazi shadows in work by Italo Calvino, Primo Levi and Giorgio Bassani) Ginzburg's The Dry Heart will have you thinking again. Merve started her piece by asking that age-old question: "When should a woman kill her husband?
Ameliorating effects of exercise on disrupted epididymal sperm parameters in high fat diet-induced obese rats
No full textObjective: Obesity causes male infertility problems and affects the sperm quality. Recent studies have shown that exercise has positive effects on male fertility. The present study aimed to show the effects of swimming exercise on the epididymal sperm number, motility and morphology in hight fat diet (HFD)-induced obese rats. Materials and Methods: Four experimental groups (n=8 in each group) were formed. Standard (STD) and STD+Exercise (STD+EXC) groups were fed with standard rat diet (6% of calories as fat); HFD and HFD+Exercise (HFD+EXC) groups were fed with high fat diet (45% of calories as fat) for 18 weeks. The rats in STD+EXC and HFD+EXC groups were trained by swimming sessions (1 h per day for 5 days a week) during the last 6 weeks of the experiment. The left caudal epididymis was prepared to evaluate the number, motility and morphology of the spermatozoa. The right epididymal samples were processed for histological evaluation. Results: Normospermic parameters were seen in STD and STD+EXC groups. Sperm number and motility decreased and spermatozoa with abnormal morphology increased significantly in HFD group when compared with STD group. A large number of spermatozoa in the epididymal duct lumen and regular morphology of the fibromuscular connective tissue were observed in STD and STD+EXC groups. Most of the epididymal ducts consisted of decreased amount of spermatozoal accumulation in the HFD group. Degenerated pseudostratified columnar epithelium with vacuole formation were additional findings in this group. On the other hand, swimming exercise had an enhancement effect on sperm parameters with prominent spermatozoal accumulation in the ducts of epididymis in HFD induced obese rats. Conclusion: This study shows that HFD-induced obesity decreased the number and motility of spermatozoa, increased abnormal spermatozoa and caused disrupted epididymal morphology. We hypothesize that exercise enhanced HFD-induced spermatogenic and epididymal damages by the regulation of scrotal heat and possible inhibition of oxidative damage in the epididymis

Prof. Dr. Ercan Ceyhan tarafından geliştirilen PS1842442, PS1842941, PS1842121, PS1842231, PS1842444, PS1842754 ve PS1842906 hatları ile kontrol çeşitleri olan Emirbey, Granger ve Melrose üzerine yapılmıştır. Çalışma, 2022-2023 yıllarında Konya ve Doğanhisar lokasyonlarında, dört tekrarlamalı tesadüf blokları desenine göre gerçekleştirilmiştir. Araştırma sonuçları, Konya'da bitki başına ortalama dal sayısının 2.44, Doğanhisar'da ise 2.76 olduğunu ve Doğanhisar'ın daha yüksek dal sayısı ürettiğini göstermektedir. Bitki boyu Konya'da 90.31 cm, Doğanhisar'da ise 104.31 cm olarak ölçülmüş; Emirbey çeşidi her iki lokasyonda da en yüksek bitki boyuna sahipken, PS1842941 en düşük bitki boyunu göstermiştir. Bakla sayısı Konya'da ortalama 16.21, Doğanhisar'da ise 24.13 adettir. Çiçeklenme süresi Konya'da 192.55 gün, Doğanhisar'da ise 207.55 gündür; Doğanhisar'daki süre daha uzundur. Fizyolojik olgunluk süresi Konya'da 237.58 gün, Doğanhisar'da ise 251.33 gündür ve yine Doğanhisar'da belirgin şekilde daha uzundur. Verimlilik açısından bakıldığında, Konya'da ortalama biyolojik verim 712.37 kg/da, Doğanhisar'da ise 1056.86 kg/da olarak bulunmuş; Doğanhisar'daki verim belirgin şekilde daha yüksektir. Tane verimi Konya'da ortalama 196.82 kg/da, Doğanhisar'da ise 299.69 kg/da'dır. Kes verimi Konya'da 515.54 kg/da, Doğanhisar'da 757.17 kg/da olarak ölçülmüştür. Hasat indeksi Konya'da 27.77, Doğanhisar'da ise 28.53'tür ve Doğanhisar'daki değerler daha yüksektir. Araştırma, bezelye hatlarının çevresel koşullardan ve genotip özelliklerinden kaynaklanan farklılıkların, bitki verimliliklerini önemli ölçüde etkilediğini ortaya koymaktadır. Çalışmanın bulguları, bezelye hatlarının her iki lokasyondaki (Konya ve Doğanhisar) verimliliklerinin farklılık gösterdiğini, özellikle Doğanhisar'ın daha yüksek verim sağladığını göstermektedir. Bu durum, Doğanhisar'ın çevresel koşullarının bezelye yetiştiriciliği için daha elverişli olduğunu ve bu bölgenin bezelye bitkisinin optimum verim sağlama potansiyeline sahip olduğunu işaret etmektedir. Sonuç olarak, çevresel faktörlerin ve genotip özelliklerinin, bezelye hatlarının verimlilikleri üzerindeki etkisi belirgin şekilde değişkenlik göstermektedir ve Doğanhisar'ın bezelye yetiştiriciliği için daha uygun bir yer olduğu sonucuna varılmaktadır.This study was carried out to evaluate the herbage yield and agronomic characteristics of forage pea (Pisum sativum L. ssp. arvense) lines. The study was conducted on the lines PS1842442, PS1842941, PS1842121, PS1842231, PS1842444, PS1842754, and PS1842906 developed by Prof. Dr. Ercan Ceyhan and the control varieties Emirbey, Granger, and Melrose. The study was conducted in Konya and Doğanhisar locations in 2022-2023 according to the randomized block design with four replications. The study results showed that the average number of branches per plant was 2.44 in Konya and 2.76 in Doğanhisar, and Doğanhisar produced a higher number of branches. Plant height was measured as 90.31 cm in Konya and 104.31 cm in Doğanhisar; the Emirbey variety had the highest plant height in both locations, while PS1842941 showed the lowest. The average number of pods was 16.21 in Konya and 24.13 in Doğanhisar. The flowering period was 192.55 days in Konya and 207.55 days in Doğanhisar; the duration in Doğanhisar was longer. The physiological maturity period is 237.58 days in Konya and 251.33 days in Doğanhisar, and it is also significantly longer in Doğanhisar. Regarding productivity, the average biological yield was 712.37 kg da-1 in Konya and 1056.86 kg da-1 in Doğanhisar; the yield in Doğanhisar was significantly higher. Seed yield averaged 196.82 kg da-1 in Konya and 299.69 kg da-1 in Doğanhisar. The straw yield was 515.54 kg da-1 in Konya and 757.17 kg da-1 in Doğanhisar. The harvest index was 27.77 in Konya and 28.53 in Doğanhisar, and the values in Doganhisar were higher. The study reveals that the differences in pea lines due to environmental conditions and genotype characteristics significantly affect their plant productivity. The findings of the study show that the productivity of pea lines in both locations (Konya and Doğanhisar) differed, primarily when Doğanhisar provided higher yields. This indicates that the environmental conditions of Doğanhisar are more favorable for pea cultivation, and this region has the potential to provide the optimum yield of pea plants. In conclusion, the effect of environmental factors and genotype traits on the productivity of pea lines varies significantly. It is concluded that Doğanhisar is a more suitable location for pea cultivationBu tez çalışması Selçuk Üniversitesi Bilimsel Araştırma Projeleri (BAP) tarafından 23201073 nolu proje ile desteklenmiştir
Bioethanol Production from Mulberry Molasses Waste with Ohmic-Assisted Hydrodistillation
No full textIn this study, the fermentation process of bioethanol production conditions were optimized by response surface methodology. Mulberry molasses production waste was used as the only carbon source for yeast fermentation to produce bioethanol. Hydrodistillation (HD) and ohmic-assisted hydrodistillation (OAHD) methods were employed to concentrate the bioethanol. Fermentation time (48–168 h), waste matter rate (5–45%) and pH (5–7) were selected as independent variables. Alcohol concentration was treated as the response. Optimum fermentation conditions were determined as 96.894 h fermentation time, 45% waste ratio and pH 7. At these optimum conditions, alcohol concentration was determined as 3.77 ± 0.33%. While the distillate obtained in the HD method contained 22.50 ± 1.89% alcohol, it showed 27.72 ± 0.24% in the OAHD method. The energy consumption values for OAHD and HD was 2.92 ± 0.51 and 53.24 ± 1.74 Wh/mL bioethanol, respectively. Results of study showed that the OAHD could be a cost-effective and green method to distillation of bioethanol from mulberry molasses waste. © The Author(s), under exclusive licence to Springer Nature B.V. 2024

İşbu eserlerde bir taraftan Kur'an'da yer alan tüm hususlar en ince ayrıntısına kadar aktarmaya özen gösterilirken bir taraftan da dinin kurallarının, muhatapları tarafından tam anlaşılması için tercüme edilen dilin tüm inceliklerinden yararlanılmıştır. Çalıştığımız bu eser, Bursa'da hayatını kaybetmiş bir zâtın kitaplığında bulunmuş, fotoğraflanarak tarafımıza gönderilmiştir. Eser sırası bozuk bir şekilde tertip edildiğinden ilk öncelikle sûrelerin sıraları takip edilerek tekrardan nizamlanmıştır. Çalışmamız Nebe Sûresi'nden başlamış Tebbet Sûresi ile sonlanmıştır. Yani Amme Cüzüdür. Satır altı tercümesi ve tefsirle birlikle oluşturulan bu eserin müellifi hakkında bir bilgiye sahip değiliz. Her varak 11 satırdan oluşmaktadır. Çok sık olmamakla birlikte yazar derkenarlarla açıklamalarına ekleme ya da yanlışlarına düzeltme yapmıştır. Eserin yapraklarının çeşitli yerleri ıslanmış olduğundan bazı kelimeler çözümlenememiştir. Çözümlenemeyen bu kelimeler noktalanarak boş bırakılmıştır. Eserin giriş kısmında Kur'an tercümeleri üzerine yapılan çalışmalara değinilmiştir. Daha sonra eserin grameri çalışılmıştır. Akabinde eserin transkripti yapılmıştır, tıpkıbasımı sunulmuştur. Sonuç bölümünde eserin değerlendirilmesi yapılmış ve son olarak da eserin sözlüğü dizin olarak oluşturulmuştur.In the period of Old Anatolian Turkish, the works written under the line technique and this work we are working on reveal the vocabulary and vocabulary of our language on the one hand and the 14th-15th. centuries in other languages reveals its strength. In these works, on the one hand, all the issues in the Qur'an are taken into consideration in detail, while all the subtleties of the translated language are used to fully understand the rules of religion by its interlocutors. This work we have worked in has been found in the library of a person who lost his life in Bursa and has been photographed and sent to us. Since the order of the work was arranged in a distorted way, the first order of suras was followed and reorganized. Our study started from Surah Nebe and ended with Surah Tebbet. In other words, it is public. We do not have any information about the author of this work, which was created in co-operation with an inline translation and commentary. Each leaf consists of 11 lines. Although not very common, the author has made additions or corrections to the explanations with the margins. In the introduction part of the work, the studies on Qur'an translations are mentioned. Then the grammar of the work was studied. Subsequently, the transcript of the work was made, just as it was printed. In the conclusion section, the work was evaluated and finally the dictionary of the work was created as an index.
New results for optimization in stochastic networks
No full textWe are interested in single commodity stochastic network design problems under probabilistic constraint with discrete and continuous random variables. We use a stochastic programming model under probabilistic constraint (also called a chance-constrained model) to study these problems. The problem addressed in this research is how to find minimum cost optimal capacities at the nodes and/or arcs subject to the constraint that the demands should be met on a prescribed probability level (reliability constraint). In our first problem formulation, we formulate the reliability constraint in terms of the Gale-Hoffman feasibility inequalities. In latter formulations, we allow system to meet the demand at least -out-of- and consecutive -out-of- periods. The number of reliability constraints, in both cases, increases exponentially with the size of the nodes and therefore we identify the redundant constraints and reduce their number with elimination methods. Even with the reduced number of inequalities, it is not simple to solve probabilistic constrained stochastic network problems due to the large number of efficient points that satisfy the probabilistic condition. To overcome the size limitation of the problem, we develop a new theorem for efficient point generation in the case when the random variables are discrete, and we use hybrid cutting plane / supporting hyperplane algorithm in the case when the random variables are continuous.Ph.

teknolojilerindeki gelişmelerle birlikte köklü bir değişim ve dönüşüm
sürecine girmiştir. Endüstri toplumundan büyük ölçüde farklılaşan yeni
toplumu tanımlamak için birçok değişik kavramlar ortaya çıkmıştır.
Daniel Bell (1973) tarafından “post-endüstriyel toplum” (veya “endüstri
sonrası toplum”) olarak adlandırılan bu yeni toplum için hizmet sınıflı
toplum” (Dahrendorf), “enformasyon toplumu” (Masuda), “modernlik
sonrası çağ” (Etzioni), “bilgi toplumu” (Drucker), “teknokratik çağ”
(Brzezinski) ve “üçüncü dalga” (Toffler) gibi kavramlar da kullanılmıştır. Yeni toplumu tarif etmek için farklı kavramlar ve teoriler üretilse
de temelde bu teoriler arasında büyük benzerlikler bulunmaktadır. Kullanılan
kavramlardan anlaşılacağı üzere, post-endüstriyel toplum teorik
bilgininin önem kazandığı ve bilgi işçilerinin sayısının arttığı, hizmet
sektörünün genişlediği, enformasyon teknolojisinin hızla geliştiği ve
yaygınlaştığı, modemite ve positivizm kavramlarının sorgulandığı bir

High cholesterol diet activates ER stress mediated apoptosis in testes tissue: Role of alpha-tocopherol
No full textThe seminiferous tubules where spermatogenesis occurs are enveloped and protected by the Sertoli cells to support germ cells undergoing meiosis to produce haploid gametes. Clearly, induction of apoptosis in seminiferous tubules leads to abnormalities in spermatogenesis and male infertility. Studies demonstrated that increased hyperlipidemia impairs male infertility and spermatogenesis by enhancing seminiferous tubules apoptosis. However, molecular mechanisms underlying high-cholesterol-mediated testicular damage remain poorly elucidated. In this scope, we established a rabbit model and investigated the role of endoplasmic reticulum (ER) stress on high cholesterol diet induced seminiferous tubule apoptosis. Histopatological examinations revealed increased seminifer tubule apoptosis in testes of rabbits fed high cholesterol diet. In addition, phosphorylated forms of IRE1 and PERK, two well-identified markers of ER stress, were significantly induced in accordance with high cholesterol diet. High cholesterol diet also exhibited CHOP induction in testes, indicating increased ER stress related apoptosis. Supplementation of alpha-tocopherol significantly attenuated cholesterol mediated ER stress, and restored seminiferous tubules apoptosis. Taken together, our findings suggest that alpha-tocopherol might be capable to reduce testicular damage via ameliorating histopatological features and inhibiting seminiferous tubules apoptosis in hypercholesterolemic rabbits
