Determining The Efficiency Of Rapid Damage Assessment Studies After The 6 February Kahramanmaraş Earthquakes
Get PDFMimarlık Bilimleri ve Uygulamaları DergisiReferred to as “the disaster of the century”, Kahramanmaraş earthquakes have exposed the significant seismic vulnerability of many buildings in Türkiye. The February 6, Kahramanmaraş earthquakes, which are the focus of this study, had a very wide impact area, and high intensity, and the limited number of expert teams, resulted in insufficient damage assessment studies. This study aims to examine the suitability of the RYTEİE method for application in Türkiye and to assess the parameters of the method used during the February 6, Kahramanmaraş earthquakes. Data obtained from damage assessment studies revealed critical issues, such as improper establishment of the relationship between buildings and the ground, non-compliance with relevant regulations, and a lack of adequate inspection. Accordingly, the necessity of interdisciplinary cooperation for all structures was emphasized in the study. Considering the earthquakes that cause loss of life and property, this study aims to contribute to the literature
Unorthodox: Muhalif Bir Tipin Kimlik Arayışı Üzerine Sosyolojik Değerlendirme
Get PDFSinop Üniversitesi sosyal bilimler dergisiGündelik hayatın kalıplarını ve değerlerini farklı tipolojiler üzerinden görmek mümkündür. Bu noktada toplumsal yapının dinamiklerini anlamak ve anlamlandırmak için görsel sosyoloji önemli ip uçları sunmaktadır. Film ve dizilerde kullanılan görsel imgeler top-lumsal arka planın anlaşılmasında işlevseldir. Toplumsal yapının görselleşmesinde mekan ve kültür değişimi, toplumsal tipolojiler, kimlik süreçleri ve zamansal öğeler sıklıkla konu edilmektedir. Toplum analizinde en hızlı ve kolay yol çoğu zaman tipolojilerin kavranmasından geçmektedir. Çünkü toplumsal tipolojiler bir toplumun kültürel baki-yesini aksettirmektedir. Toplumun sosyalleşme pratiklerinin anlaşılmasında toplumsal tipolojiler yadsınamaz bir gerçekliktir. Alışılmışın dışında bir kimlik ve zihniyeti temsil eden “muhalif” toplumsal tipolojisinin izlerinin anlaşılmaya çalışıldığı bu çalışmada, Un-orthodox dizisi özelinde muhalif bir tipin kimlik inşa sürecinin incelenmesini amaçlanmak-tadır. Muhalif bir tipolojinin gündelik hayatı anlamlandırması ve kültürel izleri çalışmanın odağıdır. Muhalif tipolojisinin var oluş sürecinin anlaşılması adına değişim pratikleri keşfedilmeye çalışılmıştır. Nitel araştırma yöntemiyle ele alınan çalışmada doküman inceleme veri toplama yöntemi kullanılarak betimsel analizle değerlendirilmiştir. Muhalif tipi ve kimlik kapsamına girebilecek “aile ve cemaate karşı kadının duruşu”, “muhalif tipolojisinin görünümü”, “aidiyet arayışı” ve “kimlik inşa süreci” gibi temalar bulunmuştur. Bu çerçevede muhalifin sosyokültürel ve mekânsal ilişkiler ekseninde analiz edilmiştir. Kural ve sınırlara uymayan bir kültür ve zihniyeti gerekli kılan muhalifin sosyal ilişki form-ları ve kimlik edinme stratejisi yeniden üretilmektedir
Are Vascular Endothelium And Angiogenesis Effective Microrna Biomarkers Associated With The Prediction Of Early-Onset Preeclampsia (Eope) And Adverse Perinatal Outcomes?
Get PDFREPRODUCTIVE SCIENCESMicroRNA is associated with angiogenesis, invasion, proliferation, and vascular endothelial remodeling of various diseases. We aimed to investigate serum MicroRNA (miRNA) levels in preeclampsia (PE) and to determine whether any changes in miRNA levels are useful in predicting early onset preeclampsia (EOPE) and adverse perinatal outcomes. A total of 89 pregnant patients were enrolled in this prospective case-control study (55 PE and 34 healthy controls). miR-17, miR-20a, miR-20b, miR126, miR155, miR-200, miR-222, and miR-210 levels were studied in maternal serum in preeclamptic pregnant women. Multiple logistic regression analyses analyzed the risk factors which are associated with EOPE and adverse maternal outcomes. The Real-time RT-PCR method was used to determine maternal serum miRNA levels. Serum miR-17, miR-20a, miR-20b, miR126, and miR-210 levels were significantly higher in PE than the control group (p < .001, p < .001, p < .001, p < .001 and p .047 respectively). Increased miR-17, miR-20a, and miR-20b levels were independently associated with PE (OR: 0.642, 95Cl: 0.486-0.846, p .002; OR: 0.899, 95Cl: 0.811-0.996, p .042 and OR: 0.817, 95Cl: 0.689-0.970, p .021). Increased miR-17 and miR-126 levels were negatively correlated with serum EOPE in PE (r -.313, p .020), and increased miR-210 levels were significantly positively correlated with EOPE in PE (r .285, p .005). Increased expression of serum miR-17, miR-20a, miR-20b, miR126, and miR-210 were found to be associated with PE, also increased expression of miR-17, miR-20a, and miR-20b were to be predicted with PE, also increased maternal serum miR-17 and miR-126 expressions were negatively correlated and increased miR-210 expression was positively correlated with EOPE in PE women
Damage Tolerance Of Basalt Fiber Reinforced Multiscale Composites: Effect Of Nanoparticle Morphology And Hygrothermal Aging
Get PDFCOMPOSITES PART B-ENGINEERINGBarely visible impact damages of fiber-reinforced polymers (FRPs) have been the subject of much systematic investigation, specifically with the combination of the service conditions. Introducing nanoparticles into the polymer matrix is an effective strategy to improve the impact resistance and aging performance of FRPs. However, the effect of nanoparticle morphology on the mechanical performance and damage tolerance of hygrothermally aged FRPs has yet to be extensively investigated. Here, we report the effect of silica (SiO2, 0D), halloysite (HNT, 1D), and montmorillonite clay (NC, 2D) nanoparticles on the damage tolerance of basalt fiberreinforced epoxy composites, considering their environmentally harsh service conditions. The ceramic nanoparticle-modified epoxy represented the highest mechanical performance in the case of 2 wt nanoparticle addition for all nanoparticle types. The efficiency of ceramic nanoparticles altered with the loading type in the epoxy nanocomposites. SiO2 nanoparticle-modified epoxy demonstrated the highest tensile strength (44 increase), while HNT nanoparticle-modified epoxy demonstrated the highest flexural strength (30 increase). The hygrothermal aging resulted in a slight increase in the impact performance of multi-scale FRPs. In contrast, the HNT nanoparticle-modified multi-scale FRPs exhibited the highest impact resistance with an increase of 8 in impact load. Dynamic mechanical analysis revealed the multi-scale composite's crosslinking density increased drastically (47 ) with hygrothermal aging, which increased the storage modulus (14 ) and glass transition temperature (15.7 ) due to physical aging effects as revealed by FTIR analysis. Compression after impact tests showed that the compression strength of HNT-modified multi-scale composites increased 17.8 after the aging. This study provides valuable insights into developing and performing multiscale composites for demanding aviation and wind energy applications
Gravity Model Of Trade Approach: What Drives Indonesia's Seafood Export And Its Halal Market Potency In Oic (Organization Of Islamic Cooperation) Countries
Get PDFJOURNAL OF ISLAMIC MARKETINGPurposeThis study aims to unveil the variables that drive Indonesia's seafood exports to organization of Islamic cooperation (OIC) countries, including a deeper analysis to understand the factors that affect Indonesia's potential for halal seafood exports, and attempts to validate Linder's hypothesis, which might occur as part of the determinants of Indonesia's seafood exports, as well as one of the variables that can affect Indonesia's potency of halal seafood exports based on economic scale similarities and relative factor endowments.Design/methodology/approachUsing Poisson regression by pseudo maximum likelihood, this study applies the theory of trade gravity and Linder's hypothesis of Indonesia's seafood exports to OIC countries and its halal market potency over the 30 years observation period from 1992 to 2021, with 47 countries importing Indonesia's seafood products during the observation period based on United Nations Comtrade statistics.FindingsThe variables that drive Indonesia's seafood exports are the situation of the economy between Indonesia and its trading partners, the population of importing countries and the common understanding of language. On the other hand, the adjusted-Muslim GDP of importing countries, the adjusted-Muslim GDP of Indonesia and the number of Muslim inhabitants of importer countries are the factors that affect Indonesia's potential for halal seafood exports. The study also validates the presence of Linder's hypothesis in Indonesia's seafood export and could hint Indonesia's potential for halal seafood exportsResearch limitations/implicationsOwing to the absence of an Harmonized System code that explicitly accommodates trade in halal commodities, especially in halal seafood exports, it will be more accurate if data are available in the future as material for further studies. Future studies may also consider per capita consumption of seafood, food safety standards and the level of food security from OIC countries as variables that might also influence Indonesia's seafood exports in an approach analysis using the gravity theory of trade.Practical implicationsThis study is part of the authors' efforts to encourage a greater contribution of the fisheries sector to Indonesia's GDP by identifying the factors that drive seafood exports, which have so far only been around 2-3 and have never reached more than 4 in the past two decades. While Indonesia is blessed with extraordinary marine biodiversity and hopes of being the leader of the halal food industry, the fisheries sector is expected to contribute.Originality/valueUnlike previous studies that used the approach of the gravity model of trade on food exports, this study is specifically in the field of seafood exports, takes Indonesia as the main object of research and also examines Linder's hypothesis as part of the analysis to identify what drives Indonesia's seafood exports in the OIC countries market and fill the scant of studies highlighting the factors that could drive halal food exports, specifically in seafood
Effects Of Different Coating Layers On Some Surface Properties Of Wax-Applied Plum (Prunus Domestica L.) WoodBalmumu Uygulanmış Erik (Prunus Domestica L.) Odununda Bazı Yüzey Özellikleri Üzerine Farklı Kat Sayılarının Etkileri
No full textSivas Cumhuriyet Üniversitesi Mühendislik Fakültesi DergisiSivas Cumhuriyet Üniversitesi Mühendislik Fakültesi DergisiIn this study, the effects of different coating layers (1, 2, and 3) on some surface properties (glossiness, color parameters, and whiteness index: WI) of wax-applied plum (Prunus domestica L.) wood were investigated. According to the results, the factor of the number of layers was found to be significant in all tests based on the analysis of variance. With an increase in the wax layer count, the L, ho, and WI values decreased in both directions. a, C, b, and the glossiness values at 60 and 85 degrees increased in both directions. ∆E values were determined as 9.16 for 1 layer of wax, 11.36 for 2 layers, and 11.14 for 3 layers. It’s evident that wax causes a change in the surface properties of the wooden material, and additionally, as the ∆E values for the 2 and 3 layer applications are close to each other, it can be suggested that a 3-layer application might not be necessary.Bu araştırmada, balmumu uygulanmış erik (Prunus domestica L.) odununda bazı yüzey özellikleri (parlaklık, renk parametreleri ve beyazlık indeksi: WI) üzerine farklı kat sayılarının (1, 2 ve 3) etkileri araştırılmıştır. Sonuçlara göre, varyans analizi sonuçlarında kat sayısı faktörü açısından bütün testler anlamlı olarak tespit edilmiştir. Balmumu uygulamasına ait kat sayısının artmasıyla L, ho ve WI (her iki yönde) değerleri azalmıştır. a, C, b ile 60 ve 85 derecelerde yapılan her iki yöndeki parlaklık değerleri artış göstermiştir. ∆E değerleri 1 kat balmumu ile 9.16, 2 kat balmumu ile 11.36 ve 3 kat balmumu ile 11.14 olarak tespit edilmiştir. Balmumu ile ahşap malzemenin yüzey özelliklerinde değişikliğe sebep olduğu, buna ek olarak 2 ve 3 kat uygulamalarındaki ∆E değerlerinin birbirine yakın elde edilmesiyle 3 kat uygulamasının gerek olmadığı söylene bilinir

Hipotalamusu vücudun enerji depoları hakkında uyaran hormonlar, yemek yemeyi engelleyip vücut ağırlığının belli fizyolojik sınırlar içerisinde kalmasını sağlamaktadırlar. Obezite ve obeziteyle ilişkili olan hormonların araştırılması bu kapsamda çok önemlidir. Obezite ile ilişkili hormonların günümüze kadar tespit edilmiş olan fonksiyonlarının, daha ileri çalışmalara rehberlik edebileceğini düşünmekteyiz. Bu derlemede obeziteyle ilişkili hormonlar ve onların etki mekanizmalarına değinilmiştir.Obesity, which develops especially in childhood and adolescence, is an important health problem at all ages. Hormones that stimulate the hypothalamus about the body's energy stores prevent eating and keep body weight within certain physiological limits. Investigating obesity and the hormones associated with obesity is very important in this context. We believe that the functions of obesity-associated hormones that have been identified to date can guide further studies. In this review, obesity-related hormones and their mechanisms of action are discussed
