The milk sector is one of the most important pillars animal production in Egypt, as this activity has achieved about 23 billion pounds representing 24.91% total value livestock 2018, and that dairy new land amounted to 2.69 pounds, equivalent 6.91% which amounts 38.94 same year, aims measure efficiency economic farms Nobaria determine extent investment continuity reached several results, are: ...

Crude glycerol (CG), a by-product of biodiesel production, is an organic carbon-rich substrate with potential as feedstock for polyhydroxyalkanoate (PHA) production. PHA is a biodegradable thermoplastic synthesized by microorganisms as an intracellular granule. In this study we investigated PHA production on CG using mixed microbial consortia (MMC) and determined that the enriched MMC produced ...

1 Abstract—This study vitalized the uncertainty and fuzzy rules consideration in the estimation of phosphorus loadings and eutrophication status of the hydrologic system namely detention pond using Fuzzy Logic (MATLAB). These methods were chosen to cater for the uncertainty of loading factors such as sediment and phosphorus inflow, inflowing discharge and pond storage volume. The average of pho...

nitrogen is one of the most important nutrients in crop production, but it's losses to the environment is harmful. the sundial model (simulation model of n dynamics in the soil) was used to quantify the cycle of n and it's losses in different production systems of sugar beet (beta vulgaris l.) in former khorasan province, east of iran. the data were collected from traditional, semi-me...

The study first identified fully efficient farmers and then estimated technical efficiency of inefficient farmers, identifying their determinants by applying a Zero Inefficiency Stochastic Frontier Model (ZISFM) on a sample of 300 rice farmers from central-northern Thailand. Next, the study developed scenarios of potential production increase and resource conservation if technical inefficiency ...

INTRODUCTION In the Democratic Republic of Congo (DRC), the practice of blood transfusion is common with more than two hundred thousand one million blood donation per year has been made between 2007 and 2011. However, no report on iron deficiency and iron deficiency anemia as a result of a donation blood in DS is available in this country. This study aimed to estimate the extend of iron deficie...

To attain effective utilization of water in different sectors, understanding and applying the new concept management tools like footprint analysis is mandatory. Hence, this study aims to estimate green blue for selected major cereal vegetable crops Salale Zone. Ten year (2011–2020) climatic, crop yield, cultivated area data were collected. Green footprints (m3/ton), average per-kilogram each pr...

This paper presents a comparison of dry anaerobic digestion reactors fed with differently sorted municipal organic solid wastes. One reactor was fed with source sorted organic wastes and a second reactor was fed with mixed organic wastes consisting of grey wastes, mechanically selected municipal solid wastes and sludge. The two reactors utilised the same process (Valorga) and operational condit...
