Vera L. M. Huszar,Nina F. Caraco,Fabio Roland,Jonathan Coleckage, is used to render the symbolically derived parallel procedures into code for the Warp parallel computer. The generated parallel routines execute on the parallel processor under the control of a Fortran-based finite element analysis package which runs on a general purpose host computer. This a

Human activities changing the nitrogen cycle in Brazil,ilizer application and atmospheric deposition are the main sources of anthropogenic nitrogen. In Brazil, the production of soybean crops over an area of less than 20 million ha, was responsible for about 3.2 Tg N or close to one-third of the N inputs from anthropogenic sources in 2002. Moreover, cat

Along with land use, mean annual runoff explained most of the variance in fluvial N yield.

Nitrogen and phosphorus budgets for a tropical watershed impacted by agricultural land use: Guayas,sents net inputs of N and P to each watershed region. Overall, synthetic fertilizers are the largest input to the Guayas Basin for N (53%) and P (57%), and the largest outputs are N and P in crops. Losses of N and P in river export account for 14–38% of total N and P inputs, and there is significant
