Agricultural food production and consumption covers activities ranging from agriculture to food consumption. Pollution and food contamination related to the use of production technologies and processes, as well as from the use of products aimed at increasing agricultural yields and facilitating food conservation, have significant environmental consequences. There are a number of important issue...

The difficulty in representing disposable resources as formulas of classical logic motivates the study of a new logic modeling system. There are similarities and differences between resource consumption/production and theorem proving in logic. Both are about deducibility (or producibility) of a formula (or a thing). The major difference is that once a disposable resource is used to produce some...

Shortage of water resources and increasing demand to consumption of this scarce resource, leads to somenoticeable limitations. On the other hand, population growth and consequently, increasing demand for water in aridand semi arid regions , needs production in exchange of little amount of water consumption. To approach thisobjective, an experiment in the complete randomized blocks carried out i...
