Stopped-Flow Technique and Cationic Polymerization Kinetics,his technique, but owing to instrumentation they were limited to a very narrow range of temperatures (-1 to +30 °C). Furthermore the stability of carbocations depends on the experimental conditions, and experiments under vacuum in sealed vessels with highly purified reagents are required. The situat

Extreme deoxygenation in the hypolimnion of Lake Victoria has become more widespread and prolonged in recent years in response to eutrophication and decomposition of massive algal blooms. If eutrophic conditions persist, spatial expansion of hypoxic waters may reduce habitat for Nile pe

Modern δ.C values of the carbonates are depleted relative to equilibrium values and vary appreciably around the lake. The preferred exp
