Nutrition -The problem of nutrition in these young infants is made doubly difficult by a great demand for food and a poor supply. The demand for food is relatively great because of the increased heat loss of premature infants. In proportion to its bulk the little body has a large surface from which to radiate heat. In addition, the layer of non-conducting fat is thin and the heat regulating mec...

Zooplankton feeding activity is hypothesized to attenuate the downward flux of elements in the ocean. We investigated whether the zooplankton community composition could influence the flux attenuation, due to the differences of feeding modes (feeding on dispersed vs. aggregated particles) and of metabolic rates. We fed 5 copepod species-three calanoid, one harpacticoid and one poecilamastoid-mi...

The sufficient supply of food and energy requires large amounts of fresh water. Mainly required for irrigation, but also processing and cooling purposes, water is one of the essential resources in both sectors. Rising global population numbers and economic development could likely cause an increase in natural resource demand over the coming decades, while at the same time climate change might l...

The impact of consumer demand for quality on the agricultural and food system is an increased emphasis on quality differentiation but not all in the direction of upgrading quality. The more elite market segments are thriving and reaching growing numbers of consumers but the basic price/quality markets remain strong. Most recent economic studies find that consumers are willing to pay for food sa...

livestock have made major contribution to human societies by providing food, shelter, fuel, and services.  sheep and goat are economically important livestock play an important socioeconomic role for small and large farmers in libya.  small ruminant animal meat is popular for libyan customers, and demand is particularly high during religious and cultural festivals.  small ruminants is valued fo...

For labour-intensive field, appropriate storage location assignment is the best choice to increase order picking efficiency and reduce order cycle time, which satisfy customers and reduce cost at the same time. In this paper, we advance a storage location assignment for fresh food distribution center with a manual picker-to-parts picking system by using an optimized approach. To reflect the cus...

Safeguarding the world's remaining forests is a high-priority goal. We assess the biophysical option space for feeding the world in 2050 in a hypothetical zero-deforestation world. We systematically combine realistic assumptions on future yields, agricultural areas, livestock feed and human diets. For each scenario, we determine whether the supply of crop products meets the demand and whether t...
