We consider the dynamics of a slender, evaporating droplet containing nanoparticles. We use lubrication theory to derive a coupled system of equations that govern the film thickness and the concentration of nanoparticles. These equations account for capillarity, Marangoni stresses, evaporation, and disjoining pressure; the nanoparticle-induced structural component of the disjoining pressure is ...

the other hand he found that villages along the ghats* cutting the face of the plateau escarpment were intensely infected and he ll?ted that two particular villages, Angarah Bundkhela, situated at the top of the ghats otherwise apparently quite similar to filftges on the plateau were as highly infected any he had found at the foot of the scarp, ' nrr-^ley are notoriously malarious. His findings...

We report on improved gain and spectral control in co-extruded all-polymer multilayer distributed feedback (DFB) lasers achieved by folding and deliberate modification of the center "defect" layer. Because DFB laser gain is greater at spectral defects inside the reflection band than at the band edges, manipulation of structural defects can be used to alter spectral defects and thereby tune the ...

For development of a comprehensive sediment management plan, it is crucial to categorize watersheds on the basis soil erosion hotspot areas extend useful life water bodies (e.g., Gidam reservoir). The goal this study was assess surface potential and identify Gidabo watershed in Ethiopia using Soil Water Assessment Tool (SWAT) model. SUFI-2 (Sequential Uncertainty Fitting Version 2) program used...

Sedimentation is a leading global problem that affects the environment and dams by reducing live storage capacity of reservoirs life expectance dams. Hence, prioritizing watersheds according to risk soil loss crucial for extending useful reservoirs. The objectives this study were assess sediment flow in Genale Dawa-3 reservoir, identify subbasins are prone erosion, evaluate impact different man...

Terraced areas have existed in Italy since ancient times, and they continue to be characteristic elements of the cultural identity of the country. The progressive abandonment of rural areas and farmland that began in the 1960s has led to the disintegration and disappearance of many terraces, representing one of the problems connected with the deterioration of the historic Tuscan agricultural la...

The article is devoted to the research of potential and features application elements agricultural production, as well determine role urban situation in formation new housing estates. Based on analysis scientific sources, existing examples combination identified three main types that affect design clusters structure.
 first type - current dense situation. Works a means segregation various ...
