Öğe The Preventive Effects of Different Doses of Glucomannan on Experimental Aflatoxicosis in Japanese Quails(FACTA-FUNDACIO ARNCO CIENCIA TECNOLOGIA AVICOLAS, 2017) Yavuz, O.; Ozdemir, O.; Ortatatli, M.; Atalay, B.; Hatipoglu, F.; Terzi, F.This experimental study was performed to investigate whether there is a protective effect of different doses of Glucomannan using against aflatoxicosis in Japanese quail, and pathological changes and relative organ weights were compared. In the experiment, 60 one-day old male Japanese quails were used as divided into six different groups. Experimental groups were designated as Control(C), aflatoxin(A), glucomannan(GM), 2-fold dose of glucomannan(2GM), aflatoxin+glucomannan(A+GM) and aflatoxin+2-fold dose of glucomannan(A+2GM). While control group quails fed the standard ration as ad libitum, other groups were fed with the administrations additionally to standard diet respectively; 2mg/kg of aflatoxin to group A, 1g/kg of glucomannan to group GM, 2g/kg of glucomannan to group 2GM, 2mg/kg of aflatoxin and 1g/kg glucomannan to group A+GM, 2mg/kg of aflatoxin and 2g/kg glucomannan to group A+2GM. All quails were euthanized at day 21 of the study and organs, (liver, spleen, kidney, thymus and bursa of Fabricius) were removed, weighed and subjected to routine histopathological procedures. Although any important macroscopic changes were not observed in the C, GM and 2GM groups, significant pathological changes were found in the groups of A, A+GM and A+2GM. In the A+GM group, the partial reduction in the severity of microscopic lesions were seen in liver, bursa of Fabricius, thymus and spleen, however a significant reduction in severity of lesions was noticed in A+2GM group. As a result of the study, 2g/kg of glucomannan has been found pathologically to be more effective than 1g/kg glucomannan in terms of the protection against aflatoxicosis by giving orally.Öğe Radiative Lifetimes for Singly Ionized Beryllium(POLISH ACAD SCIENCES INST PHYSICS, 2016) Celik, G.; Atalay, B.; Ates, S.The theoretical lifetimes for singly ionized beryllium (Be II) have been calculated using the weakest bound electron potential model theory and the quantum defect orbital theory under the assumption of the LS coupling scheme. In the calculations, many states are considered. Some lifetime values for highly excited levels have been obtained using these methods. The lifetimes presented in this work have been compared with the early theoretical calculations and measurements presented in the literature. A good agreement with the results in the literature has been obtained.Öğe Transition probabilities of neutral scandium(CANADIAN SCIENCE PUBLISHING, NRC RESEARCH PRESS, 2014) Ozturk, I. K.; Celik, G.; Gokce, Y.; Atalay, B.; Guzelcimen, F.; Er, A.; Basar, G.The electric dipole transition probabilities and the oscillator strengths of neutral scandium have been calculated using the quantum defect orbital theory and the Cowan code for the 3d4s(2)-3d4s4p, 3d(2)4s-3d(2)4p, and 3d4s(2)-4s(2)4p transitions. In addition, a parametric analysis of the fine structure for the 3d4s(2) configuration of even parity is performed using Cowan code. The transition probabilities and the oscillator strengths obtained in this work are mostly in agreement with the data obtained from different theoretical works given in the literature. Moreover, transition probabilities for 24 levels of neutral scandium are given for the first time.
