Two primary patterns of body size variation have been recorded in ectotherms in relation to latitudinal/altitudinal shifts. In some, body size increases with increasing latitude/altitude whereas, in others, body size decreases with increasing latitude/altitude. This clinal variation is generally assumed to be caused by local adaptation to environmental conditions however the selective variable（s）（temperature, humidity, diet quality, etc.） is still heavily debated. Here we investigate geographic variation in body size of dark and pale color morphs of males of the bush-cricket lsophya rizeensis collected from 15 locations along an elevation gradient ranging from 350 to 2 500 m. Using an information theoretical approach we evaluate the relative support of four different hypotheses （the temperature size rule, the moisture gradient hypothesis, the seasonal constraint hypothesis, and the primary productivity hypothesis） explaining body size variation along the altitudinal gradient. Body size variation in pale color morphs showed a curvilinear relationship with altitude while dark color morphs showed no variation in body size. Body size variation in pale color morphs was highly correlated with precipitation and temperature seasonality values thus giving strong support for the moisture gradient and seasonal constraint hypothesis. Our results reinforce the importance of gradients in humidity and seasonality over temperature in the creation of altitudinal body size clines and the role of selection for resistance to stress factors in the establishment of these clines. Whether a body size cline is observed or not might also depend on the phenotypic properties of the individuals, like coloration.

Castleman's disease(CD), also known as angiofolicular lymph node hyperplasia, is a rare heterogenous group of lymphoproliferative disorders. Histologically, it can be classified as hyaline vascular type, plasma cell type, or mixed type. Clinically two different subtypes of the CD are present: Unicentric and multicentric. Unicentric CD is generally asymptomatic and associated with hyaline vascular type, and its diagnoses depend on the localized lymphadenopathy on examination or imaging studies. However, multicentric CD presents with generalized lymphadenopathy and systemic symptoms including malaise, fever, night sweats, weight loss, and it is associated with the plasma cell type and mix type. Herein, we report a patient with unicentric CD of the plasma cell type without systemic symptoms, who developed end stage renal failure caused by amyloidosis 6 years after onset of CD.

本研究目的在于将制革工业中产生的污泥转化为有用的材料。为了达到此目的,利用热重法(TG)和轴向固定床反应器研究了废弃污泥的热行为。以不同的升温速率升温至温度750℃进行了热重分析,在248～500℃的温度范围内观察了主要的热解分解步骤。固定床反应器中,污泥于氮气气氛中450℃和600℃热解,热解产物为气体、液体及焦炭。温度对产物组分的比例有轻微的影响。热解气有相当大的总热值(23.22MJNm-3)。尽管热解油有适当的热值,但其含有大量的含氮和含氧化合物。本文还研究了利用污泥作为生产活性炭的一种原材料。为此,通过物理和化学的活化方法从污泥中制备了活性炭。利用所选择的活性炭对亚甲基蓝、苯酚及C(rⅥ)的吸附行为进行了研究,来验证其作为吸附剂的可行性。

Underage marriages are going on to keep their commonness in countries such as Turkey although frequencies of them are decreasing in the world. According to the law, marriages before eighteen years old are also defined as early marriages. Being married of girls at early ages makes these children deprived from education life and their vicinity. Therefore severe psychological difficulties occur in these children. In this study, 19 girls, who were being married at early ages and psychologically examined between January 1st, 2013-April 1st, 2015 in physical and mental health committee of the Dicle University, Medical Faculty, were taken to evaluate. These 19 cases were retrospectively assessed in sociodemographic data (age, education level, and relative degrees), type of marriage, state of mind, forensic reports and files. Of 410 cases, who admitted to our mental and physical committee, 19 (4.6%) were at the category of early age marriage. These 19 cases range between 13 and 17 years of age. Three of them (15.8%) were thinking of suicide and one of them (5.3%) attempted suicide. At least, one mental disorder was diagnosed in 8 (42.1%) of the cases and the most common diagnose was acute stress disorder in four (21.1%) cases. It has been stated that marriages at early ages are caused by economic and cultural reasons. As conclusion, being married of children at early ages is an important risk factor in social and mental health.
