This study analyzes the optimal allocation of the world’s land resources over the course of the next century within a dynamic forwardlooking framework, which brings together distinct strands of economic, agronomic, and biophysical literature and incorporates key drivers affecting global land-use. We show that, while some deforestation is optimal in the near term, the desirability of further def...

Corporate political activity (CPA) can be an important element in any firm’s effort to gain competitive advantage. This has been particularly true in the area of international trade, where domestic producers seek to bar or disadvantage foreign competitors in the home market though the imposition of trade protection. In the United States the imposition of anti-dumping duties (AD) or countervaili...

the isogeometric analysis is increasingly used in various engineering problems. it is based on non-uniform rational b-splines (nurbs) basis function applied for the solution field approximation and the geometry description. one of the major concerns with this method is finding an efficient approach to impose essential boundary conditions, especially for inhomogeneous boundaries. the main contri...

In the time of the Chinese emperor, Shen Nung, about 2700 B.C., Cannabis was mentioned as a subject of controversy; this state of affairs has continued ever since (Grinspoon, 1969). It will be remembered that with alcohol, another controversial self-administered substance known to have toxic effects, the imposition of a large tax on gin in the 18th century (a social measure, not a medical one) ...

We examined the effect of amiloride on Na+-H+ exchange in rabbit renal cortical microvillus membrane vesicles. Amiloride inhibited both the uphill Na+ accumulation induced by imposition of a transmembrane Hin+ greater than Hout+ gradient and the uphill H+ efflux induced by imposition of a Naout+ greater than Nain+ gradient. The inhibitory effect of amiloride on Na+ influx was rapidly reversible...
