We present a logical formalism of the actor-based concurrent object oriented computation in terms of the deduction in linear logic. By encoding messages and objects in the actor model as formulae of linear logic, the distributed state of the actor computation, regarded as a connguration, can be represented as a multiset of object formulae and message formulae. Methods are encoded as a special f...

In large regions of the world, biomass is a very important source of energy. The global bioenergy market based on forest biomass is growing rapidly. About 92 % of the bioenergy in Sweden comes from forests. Biomass from forests is not homogenous. The locations, transport distances, and transport methods, can differ very much and the industries that need biomass as input prefer raw materials wit...

Abstract Biohydrogen production in agricultural enterprises is an urgent matter. It appropriate to utilize two methods of biohydrogen production: a thermochemical method – from crop-based biomass and anaerobic digestion (fermentation) animal-based biomass.. use gasifiers for the biore-actors fermentation method. The theoretical potential was established with due regard amount which necessary ut...

Background and purpose: Studies show that surface or subsurface water in some areas near to the pollutant sources, to an extent higher than the permisible potable limit are contaminated with cadmium. There are different reports about biological absorption of cadmium in high concentrations (present in industrial effluents) by bacterial biomass, but there is less report about removing of low co...
