Effects of Elevated Temperature on Agronomic, Morphological, Physiological and Biochemical Characteristics of Potato Genotypes: 1. Agronomic and Morphological traits
Get PDFGlobal elevated temperatures create uncertainties in crop yield production and sustainability, threatening potatoes' food security and sustainability roles. This has been among the primary research concerns necessitating the need to evaluate potato genotypes' response to elevated temperature under field conditions. This study assessed potato genotypes' agronomic and morphological responses to elevated temperatures. The experiments were conducted under field conditions in the 2022 and 2023 cropping seasons in a split-plot design. Two heat treatments were applied; a control treatment in which the plants received the field temperature of the experimental station, and a heat treatment in which the plants received a temperature of + 6.0-10.0 degrees C depending on the date and time of day. The agronomic and morphological traits evaluated included tuber yield, mean tuber weight, days to emergence, plant height, number of stems per plant, days to physiological maturity, and tuber size distribution. The results showed significant (P < 0.01) variations in the potato genotypes in response to elevated temperature in all traits except days to emergence. Elevated temperature promoted plant height by 36.94%, and days to physiological maturity by 2.55%, while reducing the number of stems per plant by 11.77% and days to emergence by 2.31%. Furthermore, elevated temperature increased total tuber yield by 25.38%, the number of tubers per plant by 18.75%, mean tuber weight by 8.89%, third-class tuber size distribution by 25.95% and malformed tuber ratio by 1.98%, while decreasing first-class tuber size distribution by 10.11%, second-class size distribution by 1.70% and marketable tuber yield by 4.22%. The results of this study demonstrated the impact of heat stress on potato tuber yield and size distribution. The study showed that temperatures around 27.0 degrees C to 33.0 degrees C effectively promoted total tuber yield, number of tubers per plant and mean tuber weight; thus, an increase in temperature within the effective range of potato plants promoted yield and yield-related components. This study demonstrates that open-sided field chambers can be a screening tool for heat tolerance of potato genotypes under field conditions. Potato genotypes with less variation in the traits between the heat and control treatment demonstrate heat tolerance and could be used as selection markers for heat-tolerant genotypes.Nigde Omer Halisdemir University Research Project Units [TGT 2021/24-OENAP]This research is part of Eric Kuopuobe Naawe's PhD research.

Hicret Özelinde Sünnetin Kur’an’ı Neshi
Get PDFİslam dininde vahyin insan yaşamına etkisi çeşitli evrelerde gerçekleşmiştir. Bu süreçte, dönemin koşulları göz önünde bulundurularak bazı geçici hükümler devreye sokulmuş, amaçlar gerçekleşince bu hükümler değiştirilerek asıl hükümler belirlenmiştir. Nesh olgusu, hayatın akışı içinde doğal bir zorunluluk olarak ortaya çıkmıştır. Bu uygulama, tedricilik ve kolaylaştırma prensipleriyle yaşamın gerçeklerine uygunluğuyla ilgili çeşitli ilim dallarının ilgisini çekmiştir. İslam âlimleri, bu konuyu farklı şekillerde ele almış ancak sünnetin Kur'an'ı nesh etme konusu çeşitli tartışmalarla ön plana çıkmıştır. Sünnetin Kur'an'ı nesh edebileceği üzerine yapılan çalışmalar belli örnekler etrafında gerçekleşmiş, ancak bu örneklerin neshi mümkün kılabilecek güce sahip olmadığı iddia edilmiştir. Bu makalede, sünnetin Kur'an'ı nesh etme konusu usul kitaplarında bulunmayan bir örnek üzerinden incelenmiştir. Bazı ayetlerde Mekke’den Medine’ye hicret bir iman şartı gibi sunulmuş, bilhassa Nisa Suresi 97. ayette hicret şartını yerine getirmeyenler cehennemle tehdit edilmiştir. Ancak bu denli kati bir üslupla ifade edilen hicret emrinin bazı hadislerle nihayete erdiği ve inkıtâya uğradığı bildirilmiştir. Bu manzara hicret olgusu üzerinden Kur’an’ın sünnet ile neshi tartışmalarına imkân vermektedir. Makalede bu konu İslam âlimlerinin görüşlerine de yer verilmek suretiyle, hicret farizasının sürekliliği farklı sosyo-politik ve dini bağlamlar çerçevesinde ele alınmıştır

The study group of the research consists of 45 sixth grade students from a middle school located in Pozantı district of Adana province. In accordance with the study's objective, a mixed-method research approach, combining both quantitative and qualitative research methods, was adopted, with a preference for the explanatory sequential design. For quantitative data collection, a pre-test-post-test non-equivalent control group quasi-experimental design was used. Initially, experimental and control groups were established. Both groups were administered a pre-test achievement test and attitude scale before the intervention. Subsequently, while mathematics instruction for the experimental group was carried out using digital stories, the control group received no intervention and was taught using the methods included in the existing curriculum. After the intervention, a post-test achievement test and attitude scale were administered to both groups. Qualitative data were collected through interviews with students in the experimental group about their experiences after the intervention. Independent sample t-tests were used for the analysis of quantitative data due to the normal distribution of data for comparisons between groups, and dependent sample t-tests for within-group comparisons; content analysis was utilized for the analysis of qualitative data. The results of the research indicate that mathematics instruction carried out with digital stories significantly improved the academic achievements in mathematics and attitudes towards mathematics of students in the experimental group, positively affecting them. The feedback from the students about the process was positive, indicating that the use of digital stories during lessons generated interest, motivated the students, increased their participation in class, helped them understand the subject, and that the students greatly enjoyed the process

Bodybuilders and high-level meat consumers' behavior towards rabbit, beef, chicken, turkey, and lamb meat: A comparative review
Get PDFIn bodybuilders' diets, protein plays a crucial role in supporting muscle growth and repairing damaged muscle tissue. These individuals meet their protein needs by combining dietary sources with supplements. Animal-based proteins are often preferred over plant-based proteins because they are believed to better support muscle protein synthesis. This review explores the meat consumption patterns of bodybuilders and high-level meat consumers, focusing on rabbit, beef, chicken, turkey, and lamb. We describe and compare the types of meat bodybuilders commonly consume and provide an overview of protein supplements, including meat-based options, plant-based alternatives, and whey-based products. Our aim is to gain insight into the dietary preferences of bodybuilders and high-level meat consumers, considering their nutritional requirements and the potential effect on the meat industry. We conducted an extensive search across various databases, including Scopus, Web of Science, PubMed, and Google Scholar. We found that individual choices vary based on factors such as attitudes, trust, taste, texture, nutritional content, ethical considerations, and cultural influences. Nutritional factors, including protein content, amino acid profiles, and fat levels, significantly influence the preferences of bodybuilders and high-level meat consumers. However, it is crucial to maintain a balance by incorporating other essential nutrients such as carbohydrates, healthy fats, vitamins, and minerals to ensure a complete and balanced diet. The findings from this review can inform strategies and product development initiatives tailored to the needs of bodybuilders and discerning meat enthusiasts.Nobelium Joining Gdansk Tech Research Community [DEC 33/2022/IDUB/l.1, 036236]Financial support from Nobelium Joining Gdansk Tech Research Community (contract number DEC 33/2022/IDUB/l.1; NOBELIUM nr 036236) is gratefully acknowledged
