A critical review of the current taxonomy of the genus Daphnia O. F. Müller, 1785 (Anomopoda, Cladocera).
The genus Daphnia O. F. Müller, 1785 (Anomopoda, Cladocera) has become a model genus for ecological, toxicological, and evolutionary studies. At the same time, Daphnia is a well-known example of a genus with a confused taxonomy. This review aims to identify the main sources of confusion (natural and human-caused) for the current taxonomy of Daphnia. A complete check-list of all species-group na...
متن کاملAccumulation, depuration and risk assessment of cadmium (Cd) and lead (Pb) in clam (Corbicula fluminea) (O. F. Müller, 1774) under laboratory conditions
The present study investigated the accumulation and depuration of two heavy metals Cd and Pb in the freshwater clam (Corbicula fluminea) under laboratory conditions. Treated clams were exposed to single and combined treatments of Cd and Pb at the concentration of 5 mg L-1 and 10.5 mg L-1 for 10 days, respectively. The animals were then placed in metal free water for the following 5 days for de...

The Corwarative Pathology O F Carcinoma O F the Pancreas, with Report O F Two Cases in Mice
From the scanty evidence furnished by case reports, it is apparent that carcinoma of the pancreas is relatively rare in other animals as compared to its occurrence in man. According to the review of the literature on carcinoma of the pancreas in man by Kiefer (l), in 174,803 autopsies 1420 primary carcinomas of the pancreas were found, about 0.8 per cent, and among 50,494 admissions to Johns Ho...
متن کاملPD F PR O O F Public - key Primitives
Wireless sensor networks consist of tiny senor nodes with limited computing and communicating capabilities and, more importantly, with limited energy resources. In this chapter we evaluate the power consumption of Public-key algorithms and investigate whether these algorithms can be used within the power constrained sensor nodes. We evaluate conventional digital signature schemes and encryption...
