Perspektiv bakåt och framåt på medeltida stadsforskning

I uppsatsens första del diskuteras den svenska forskningen kring den medeltida staden och de linjer som kan skönjas.

Intracerebral grafting of neuronal cell suspensions. IV. Behavioural recovery in rats with unilateral implants of nigral cell suspensions in different forebrain sites

Single and multiple implants of nigral cell suspensions were grafted to the forebrains of rats with unilateral 6-hydroxydopamine-induced dopamine denervations. Control lesions alone induced a marked behavioural asymmetry, as assessed by amphetamine- and apomorphine-induced rotation, sensorimotor tests and side bias in an unbaited T-maze, and the animals were hyperactive to a low dose of apomorphin

Can Marine Micro-organisms Influence Melting of the Arctic Pack Ice?

The Arctic Ocean Expedition of 2001 (AOE-2001) to the central Arctic mostly north of latitude 85°N was conducted to study marine life forms and their products in water and ice, how their products may get into the air, the evolution of the particles produced, and their growth up to sizes large enough for activation into clouds. The expedition also investigated whether these naturally generated part
