The northern mid- to high-latitudes have the highest total number and area of lakes on Earth. Lake origins in these regions are diverse, but a large extent coupled glacial, permafrost, peatland histories. synthesis 1207 lake initiation records presented here provides an analog for rapid landscape-level change response climate warming, its subsequent attenuation by physical biological feedback m...

nanotechnology has been advanced since the last decades. among all nanomaterials that have been developed, nanosilver is the most frequently used nanoparticles. its release into natural water bodies is inevitable due to its broad applications. nanosilver (nag) was prepared via tollens method using. the morphology, size distribution and average size of the obtained nag was characterized using tr...

biogenerics production has been done in lots of advanced industrial countries since last decades and its legal aspects are adequately addressed. on the other hand, the need of our country to these drugs is inevitable and its production in recent years has begun without taking its legal aspects into account. we don’t have any legal system to regulate biogenerics production and commercialize them...

Rapid climate change characterizes numerous terrestrial sediment records during and since the last glaciation. Vegetational response is best expressed in terrestrial records near ecotones, where sensitivity to climate change is greatest, and response times are as short as decades.
