Algorithmic skeletons in conjunction with list homomorphisms play an important role in formal development of parallel algorithms. We have designed a notion of homomorphism dedicated to bulk synchronous parallelism. In this paper we derive two application using this theory: sparse matrix vector multiplication and the all nearest smaller values problem. We implement a support for BSP homomorphism...

Land use of sewage sludge is the primary disposal method in Shanxi, accounting for 42.66% of all. To determine the ecological risk of heavy metals in sewage sludge, contents of seven heavy metals in sewage sludge from 9 municipal waste water treatment plants (WWTPs) that had the highest application for land use were determined. The order of the measured concentrations was: Zn > Cr > Cu > Ni > P...

kefiran is an exogenous microbial metabolite produced mainly by bacteria and fungi during growth. the present study investigated the effects of the addition of 3% kefiran and 3% xanthan on the extensographic characteristics of wheat dough and the shelf life of raised bread. kefir grain was cultivated in a shaking incubator and kefiran extraction was carried using a centrifugal refrigerator. the...

Roasting is a process that contributes to the formation of compounds and flavors in coffee beans. Temperature length time are main factors roasting process. Generally, range temperatures times varies significantly for different varieties This study aims determine effect on changes chemical characteristics robusta beans (Coffea canephora) from Sidomulyo Village. used brewing methods brew roasted...
