This study introduces a new evolutionary approach called Binary Genetic Programming (BGP) to design and assess public transportation systems from a sustainable development perspective. The BGP combines evolutionary system identi cation techniques with k-fold cross-validation to obtain an accurate model between the land use and transportation parameters from a sustainable urban development point of view. To assess the new model, two public transportation systems including the new tram line of Antalya (Turkey) and the bus rapid transit line of Bhopal (India) were considered. The model was employ ...Daha fazlası
This study investigated parametrically the erosive wear behavior of AISI 1015 and 304 steel in different environmental conditions. The erosive wear tests were designed according to the L9 orthogonal array design of the Taguchi fractional factorial method. The experiments were carried out with the parameters of 3-level slurry concentration formed with silica powder (5, 15, and 25 wt.), 3-level impact velocity (265, 397.5, and 530 rpm), and 3-level impact angle (30°, 60°, and 90°). Surface roughness and weight loss were considered performance criteria in the experimental data assessed using the ...Daha fazlası
Bone tissue engineering (BTE) holds promise for treating bone defects, and 3D-printed porous scaffolds are pivotal for tissue regeneration. This study explores the impact of material extrusion 3D printing (ME3DP) process parameters (i.e., layer height and extrusion temperature) on 3D-printed porous scaffolds made of polyetherimide (PEI) material for BTE. The intricate relationships shaping scaffold dimensional accuracy, residual stresses, and warpage tendencies were unveiled using comprehensive numerical simulations. Our findings reveal that higher layer heights enhance dimensional stability, ...Daha fazlası
This short note reports the first record of the tomato leaf miner Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) in Kyrgyzstan. This pest was found in February 2017 in greenhouses producing tomatoes, located 15 km from Bishkek. Identification of the pest was carried out in the Plant Protection Department, Çukurova University, Turkey based on the morphology of adults and larvae and the male genitalia. According to initial surveys this pest could be a major threat to tomato production in Kyrgyzstan.
Изучение собранного местного материала в ботанико-экологическом аспекте показало, что в сортах-популяциях пшеницы наблюдалось очень большое разнообразие эколого-морфологических форм, разбросанных в разных зонах Кыргызстана. Всего в Кыргызстане найдено 60 разновидностей яровой пшеницы, относящихся к 6 видам. На территории Кыргызстана имеется несколько экологических групп. Наиболее часто встречающиеся экотипы ригидум и субригидум, относящиеся к ирано-азиатскому подвиду. В настоящее время успешно проходят государственное сортоиспытание около 80 сортов пшеницы кыргызской, казахской селекции и селе ...Daha fazlası
