Optimum utilization of available resources has became a necessary due to increasing population pressure in the developing nations. The burgeoning population put thrust on each and every resource to be utilised wisely and sustainably for production of food specially quality protein to feed the population and eradicate malnutrition. Among such underutilised resources, the saline affected land is ...

In Mediterranean environment intensive agricultural activities are often practiced in steep slopes, where sometimes climatic, geomorphologic and land use factors (e.g. the high rainfall intensity, the scarce vegetal coverage, especially on the occasion of the early rainfalls, the low organic matter content of soils, etc.) worsen the impacts of soil erosion. In such contexts agriculture may play...

This project explored the integrated use of satellite, ground observations and hydrological distributed models to support water resources assessment monitoring in High Mountain Asia (HMA). Hydrological data products were generated taking advantage synergies European Chinese assets space-borne observation systems. Energy-budget-based glacier mass balance driven by satellite developed. These can ...

external costs of environmental degradation are often ignored in economic analysis of projects. the mail goal of the paper is to economically analyze the current alternatives of meighan wetland utilization including extraction of sodium sulfate, aquaculture of artemia and integrative alternative considering external costs of wetland degradation. in order to detect eventual degradation of wetlan...

“This paper was often cited, perhaps, because it left so much more to be done in the field of metabolic regulation that it started. It described the first inductions of increased amounts of an enzyme in animal tissues by a substrate or by glucocorticoid hormones. It was a big surprise in 1951 that enzyme concentrations in cells did change. “How hormones in trace amounts could influence metaboli...

introduction: nowadays, due to lack of water resources and increasing demand for water, agricultural water planning issues need further consideration. with proper planning and determination of irrigation depth and time, the effects of stress and yield loss on the plants are reduced. irrigation scheduling is one of the most important factors in crop’s quality and quantity. the main objective of ...

The ToF atom-probe FIM was used to study surface segregation of Fe-Ti alloys. Ti segregates to the surface upon annealing at or above 650°C. The degree of segregation depends on the crystallographic orientation, 100% at the (110) and (111), 70% at the (100) and £50% at the (121) plane. It is found that the presence of H2(D2) during annealing enhances surface segregation of Ti and that oxygen de...

Life Cycle Assessment (LCA) is usually carried out using fixed coefficients for resource use and emissions as the basis for the calculation of the environmental impact of a product or a service. However, in agriculture, where the systems’ functioning largely depends on the dynamic organisation of agricultural practices and on variable climatic conditions, coupling dynamic simulation models with...
