In this article, we review animal models of types 1 and 2 diabetes mellitus. Models of type 1 diabetes are discussed in two parts, genetic and chemical. Models of type 2 diabetes are discussed in four parts – rat and mouse models, dietary induction, and selective breeding. Models are assessed regarding metabolic disturbances, the condition of the pancreas, long-term complications, and research ...

In this research, we studied the structure, properties and NMR parameters of interaction F2 gas with pristine and 3C-doped (8, 0) zigzag models of boron phosphide nanotubes (BPNTs). in order to reach these aims, we considered four different configurations for adsorption of F2gas on the outer and inner surfaces of BPNTs. The structures of all models were optimized by using density functional the...

Polycyclic Aromatic Hydrocarbon (PAH) plays an important role in the formation of combustion-generatedparticles such as soot, and their presence in atmosphere aerosols has been widely shown. The formation of five-membered rings, detected in combustion effluent, is of great interest due to their genotoxic activity.The present study reports an investigation of the electronic structure of Acenapht...

classification trees (j48) were induced to predict the habitat requirements of tench (tinca tinca). 306 datasets were used for the given fish during 8 years in the river basins in flanders (belgium). the input variables consisted of the structural-habitat (width, depth, gradient slope and distance from the source) and physic chemical (ph, dissolved oxygen, water temperature and electric conduct...
