Öğe Memenin Benign Lezyonlarından Fibromatozis(Selçuk Üniversitesi, 2021) Yılmaz, A.; Badak, B.; Şahin, A.; Işıksoy, S.Meme lezyonlarına günümüzde sıklıkla rastlanmakla beraber; özellikle bayanlarda ciddi bir sağlık sorunu haline gelmiştir. Belli başlı meme tümörleri arasında benign olarak fibrokistik hastalık ve fibroadenomlar yer alırken; malign olarak duktal ve lobuler karsinomlar ilk sıraları almaktadır. Bu olgumuzda memede kitle ile kliniğimize başvuran ve yapılan operasyon sonrası mezenkimal bir tümör olan ‘fibromatozis’ tanısı alan hastayı sunmayı amaçladık.Öğe On total vertex-edge domination(TURKIC WORLD MATHEMATICAL SOC, 2019) Şahin, B.; Şahin, A.In this paper we obtain an improved upper bound of total vertex edge-domination number of a tree. If T is a connected tree with order n, then gamma(t)(ue) (T) <= m/3 with m = 6 [n/6] and we characterize the trees attaining this upper bound. Furthermore we provide a characterization of trees T with gamma(t)(ue) (T) = gamma(t) (T).Öğe The relation between the succes level and the subjective sleeping quality of the Turkish National team that participated in the wrestling World cup1(2013) Afyon, Yakup Akif; Mamak, H.; Acar, G.; Filiz, K.; Şahin, A.; Bayköse, N.It is thought that lack of concentration and reduction of the cognitive function parallel to insomnia during the night time affect the performance of the sportsman directly. The aim of this study is to examine the relation between sleeping quality within the competition environment and the success level of the most elite sportsmen of wrestling. Study group composed of Men's Turkish National team of Freestyle wrestling that participated in the Freestyle wrestling World cup held in Teheran city of Iran in 2013 (X age=25,86 ± 3,436). To obtain the results of the study Pittsburgh Sleeping Quallity Scale was used. Kolmogrov-Smirnov test, Man whitney u, Pearson corelation analysis was used to analyze and interpret the data and meaningfulness of P<0,05 was achieved. SPSS (Statistical package for Social Sciences) 18.0 was used to evaluate and to find the calculated numbers. As a result of the study, between the degree that the wrestlers achieved and the Pittsburgh sleeping quality index scores (r=768*) strong positive relation was acquired. The meaningfulness of that relation modulus (P=,044 < 0,05) was acquired as meaningful. As a result of the data acquired through that study, it is thought that as the sleeping quality increases the success level of the wrestlers increases as well parallel to that fact.Öğe Transport of Acids Through Polyether-Sulfone Anion-Exchange Membrane(ACADEMIC PRESS INC, 2001) Ersöz, Mustafa; Güğül, İlkay Hilal; Şahin, A.Diffusion dialysis of sulfuric acid and hydrochloric acid into water with a polyether-sulfone anion-exchange membrane was studied. Transport of sulfuric acid and hydrochloric acid through the membrane has been quantified by diffusion coefficients and mass transfer coefficients. The mass transfer coefficients were investigated as a function of the rotational speed of the stirring rate of both sides of the membrane and with different pH ranges. It was observed that the diffusion dialysis seems to be dependent on the rotational speed of the stirrer; in contrast, the membrane mass transfer coefficients are independent of rotational speed, but they are slightly affected by the initial acid concentration in donor phase.
