increasing resource use efficiency is one of the important ways to enhance agricultural productions and reduce environmental hazards. for this purpose, improvement of n use efficiency is an effective approach. nitrogen losses not only occur in field but also in the processing course. the objective of this study was to calculate nitrogen losses and efficiency during production to consumption for...

Societies with low-level food production economies occupy the vast and diverse middle ground between hunting–fishing–foraging and agriculture. Efforts by Ford, Harris, Rindos, Zvelebil, and others to characterize this “in-between” territory are discussed, and a new conceptual framework is proposed. Domestication, the central landmark of this middle ground, is situated well away from the boundar...

pisciculture, especially in countries which are unable to develop their marine resources, is a desired to provide part of their food and protein needs. this study aims at investigating welfare impacts of energy subsidy removal on fish producers in fars province. to achieve the objective, cross-sectional data obtained from fish producers of fars province in 2010 was used. cost, input demand and ...

tissue nutrient supply may be synchronized with endogenous physiological rhythms to optimize animal and human health. glucose tolerance and insulin sensitivity have endogenous rhythms that are not essentially dependent on food type and eating. human glucose tolerance declines as day comes into night. based on such evolutionary findings, large evening meals must be avoided to reduce risks of vis...
