In this study, two new freshwater fish species, Gambusia holbrooki Girard, 1859 and Petroleuciscus borysthenicus (Kessler, 1859) were reported from Simenlik-Akgöl Lagoon in Yeşilırmak Basin (Samsun). Turkey has a rich biodiversity terms of fish. Because climate change, periodic ichthyofauna monitoring updating fauna are critical. holbrooki, Eastern mosquitofish, is an invasive species widesprea...
Shape memory alloy (SMA) actuators can be made very compact and simple. An effective control algorithm is an integral part of every SMA actuator. This article presents a review of the state of the art research on control of SMA systems. It is worth noting that almost exclusively all control systems applied to SMA actuators are not model-based control algorithms. In other words, the control syst...

جمعیتهای عروسماهی اصفهانی (Petroleuciscus esfahani) در رودخانه زایندهرود با استفاده از پنج جفت نشانگر مولکولی ریزماهواره بر روی 120 نمونه بالغ صید شده از چهار ایستگاه: چشمه دیمه، خرسونک، چمگردان و پل صفائیه ارزیابی شد. تمامی جایگاههای بررسی شده چندشکل بودند. تعداد 54 آلل برای پنج جایگاه تولید شد که در محدوده 6 آلل در جایگاه CnaB-030 و 17 آلل در جایگاه Ca3 قرار داشت. میانگین تعداد آلل مشاهده...
این مطالعه به منظور تعیین جایگاه آرایه شناختی عروس ماهی اصفهان با استفاده از داده های ریختی شناسی و مولکولی مربوط به ماهیان صید شده از حوضه ی رودخانه زاینده رود، طراحی شد. در مجموع 30 قطعه ماهی از منطقه ی چشمه دیمه با استفاده از تور پره صید گردید. توالی ژن سیتوکروم bو اندازه گیری های ریختی به منظور تعیین جایگاه آرایه شناختی نمونه ها مورد استفاده قرار گرفت. 25 صفت اندازشی و 7 صفت شمارشی اندازه گ...
Effects of different concentrations of silver nanoparticles and silver nitrate on some hematological indices of Zayanderud Chub (Petroleuciscus esfahani) were investigated. One hundred individuals of the fish (average weight 26.4 ± 1.3 g) were divided into 5 experimental groups, exposed to 1 or 25 µg/L of silver nano or silver nitrate or unpolluted water as control for 10 days. At the end, prim...
We consider the effect of labor market rigidities on human capital accumulation and economic growth when some human capital is difficult to observe prior to employment. We distinguish between two types of human capital, those that formal schooling and test scores can measure (“knowledge”) and those that can be observed by employers only after a period of employment (“creativity”). We build a si...
This paper develops a theory of the endogenous formation of a common market in a three–country, n factor political economy model. Ex ante policies in each of the prospective members are the result of direct democracy, and equilibrium outcomes may include both import restrictions as well as subsidies. The decision to join a common market is modelled as a simultaneous move game between the two pr...
Chemical contamination of aquatic environments to EDCs has become a major focus of environmental toxicology research. The exposure of fishes to estrogenic EDCs in aquatic environments is most frequently assessed by analyzing Vitellogenin (Vg) (the egg yolk precursor protein) expression. Therefore, characterization of Vg gene is of high priority for EDCs bio-monitoring. So, we prepared liver tis...
