life cycle study of a product is an accepted method for determining the side effects of its production process on environment during its complete life cycle. in this research, the impacts of global warming, acidification, terrestrial eutrophication and fossil resources depletion per unit yield of wheat (ton) on environment were investigated using life cycle assessment method in marvdasht region...

Tripropyltin restores medium acidification by washed corn root tissue in which electrogenic H(+) efflux has been blocked by ATPase inhibitors or injury. However, the restored H(+) efflux is not electrogenic and will not drive K(+) influx, and, by itself, tripropyltin is inhibitory to K(+) influx. Tripropyltin elicits a 5-fold increase in endogenous chloride efflux, and Cl(-)/OH(-) exchange can,...

Coccolithophores are unicellular marine algae that produce biogenic calcite scales and substantially contribute to marine primary production and carbon export to the deep ocean. Ongoing ocean acidification particularly impairs calcifying organisms, mostly resulting in decreased growth and calcification. Recent studies revealed that the immediate physiological response in the coccolithophore Emi...
