The shape of wake behind a wind turbine is normally assumed to have a hat shape for the models used in wind farm layout optimization purposes; however, it is know from experimental tests and numerical simulations that this is not a real assumption. In reality, the results of actual measurements and detailed numerical simulation show that the velocity in wake region has a S-shape profile. The pr...

soil organic carbon is a key factor in productivity and quality of soil and environment particularly in semi arid regions. in this article, the role of farm soil organic matter management in soil and in land is discussed. the variability of soil organic carbon in drylands is mainly controlled by tillage and crop residue management. results of this study indicated that usage of correct tillage m...

Majority of selected goat farmers were landless and marginal (69%) with an annual average income of Rs.I9200.00. However, average income of small and medium goat farmers were about Rs.25500.00.Ownership pattern of goats revealed that about 78% goats were owned by the landless and marginal farmers. Majority of the farmers had Barbari/Barbari type goats (54%) followed by non-descript (43%) and Si...

The present study was carried out on the seasonal abundance and diversity of zooplankton in a semi- intensive prawn farm of Bagerhat district from July to December, 2008. Plankton samples were collected by conical shaped monofilament nylon net (Plankton net) and Lugol's solution was used for preservation. The zooplankton abundance was influenced by physico-chemical factors. During the study per...

The economic well-being of most U.S. farm households depends on income from both onfarm and off-farm activities. Consequently, for many farm households, economic decisions (including technology adoption and other production decisions) are likely to be shaped by the allocation of managerial time among such activities. While time allocation decisions are usually not measured directly, we observe ...

The visualization of vector occurrence in space and time is an important aspect of studying vector-borne diseases. Detailed maps of possible vector habitats provide valuable information for the prediction of infection risk zones but are currently lacking for most parts of the world. Nonetheless, monitoring vector habitats from the finest scales up to farm level is of key importance to refine cu...
