Analysis of Magnetization as a Function of Temperature for Comn1-X Fe X Ge
(Springer, 2017) Yuce, S.; Dogan, E. Kilit; Emre, B.; Bruno, N. M.; Karaman, I.; Yurtseven, H.
Our experimental measurements for the magnetization M as a function of temperature are analyzed for the multilayer structure of CoMn1-x Fe (x) Ge for x = 0.085 and x = 0.12 at constant magnetic fields of 3, 5, and 7 T. For this analysis, a power-law formula is used below the transition temperature T-C for these compositions and the values of the critical exponent beta for the magnetization M (order parameter) are determined. Our analysis indicates that a first order transition at lower concentrations (x = 0.085) changes toward a second order at higher concentrations (x = 0.12) at constant magnetic fields (3, 5, and 7 T) for the multilayer CoMn1-x Fe (x) Ge, as observed experimentally.
Multicentral Clinical Evaluation of the Aetiology of Erectile Dysfunction: a Survey Report
(2001) Aydin, S.; Ünal, D.; Erol, H.; Karaman, I.; YIlmaz, Y.; Ş, E.; BayraklI, H.
Patients with erectile dysfunction, who admitted to 4 different urological centres in Turkey were evaluated in terms of aetiological factors to establish the aetiology of erectile dysfunction in our population and compare it with the data derived from Western communities. After the history, physical examination, psychological evaluation and laboratory testing, a clinical diagnosis was established as primarily psychogenic, organic, or mixed aetiology. Mean patient age was 43.5 years (range 17 to 69), and 9 of the patients were unmarried. Of the patients 53 had vascular risk factors, and 10 reported a history of alcohol abuse. Eleven patients were using drugs that might interfere with the disorder. In this multicentral study of 115 impotent men, an organic cause was found in 43%, psychogenic in 47%, and mixed in 19%. Mean age of the overall patients was 43.48. When the ages of the patients with organic erectile dysfunction and those with psychogenic erectile dysfunction were compared, it was clearly seen that those with organic erectile dysfunction were much older (52.73 versus 33.02).
