Hydro-Morphometric Modeling for Flood Hazard Vulnerability Assessment of Old Brahmaputra River Basin in Bangladesh - Juniper Publishers

Image
Juniper Publishers - Open Access Journal of Engineering Technology Abstract The present research introduces hydro-morphometric modeling to assess flood hazard vulnerability in old Brahmaputra River Basin in Bangladesh. Hydro-morphometric modeling is a spatial analysis in a GIS environment that has been applied for the estimation of flood hazard vulnerability. In this study the developed methodology processes information of seven parameters namely basin, flow accumulation, flow direction, stream order, stream length, stream density and drainage density. By applying Horton's and Strahler's formula of stream order, stream density and drainage density of old Brahmaputra River Basin are calculated. According to Horton's stream density and drainage density reflects the runoff and discharge status of a basin which also revealed that basin having high stream density and drainage density is most vulnerable to flooding. The old Brahmaputra River Basin subdivide...

Manufacturing Engineering Challenges of Pharmaceutical 3D Printing for on-Demand Drug Delivery - Juniper Publishers

Image
Juniper Publishers - Open Access Journal of Engineering Technology Abstract There are about two dozen 3D printing technologies available in the market. These technologies differ in terms of layering mechanism, type of material that can be handled, binding mechanism and suitability for solid dosage form manufacturing. Based on literature information and preliminary data, fused deposition modeling (FDM), selective laser sintering (SLS) and powder-bed 3D printing methods have emerged as the most promising candidates for delivering on-demand drugs according to established Good Manufacturing Practice (GMP) guidelines of the pharmaceutical industry. However, information on interplay of critical process parameters (CPPs) and critical materials attributes (CMAs) on the critical quality attributes (CQAs) of the formulations and products that will determine their in-vitro and in-vivo performance is not readily available in the literature. Through this mini-review, we ...

Using GIS Techniques to Model RUSLE’s ‘K’ Factor for River Nzoia Basin in Kenya - Juniper Publishers

Image
Juniper Publishers - Open Access Journal of Engineering Technology Abstract RUSLE is a model used to estimate mean annual soil loss. The model is a predictive tool used to evaluate land use and land cover options. Soil Erodibility (K) Factor is a measure of the predisposition of soil particles to detachment and conveyance by rainfall and surface runoff. The study sought to model soil erodibility (K) factor for river Nzoia basin, western Kenya. Geographical Information System (GIS) techniques were used to generate spatial representation of soil erodibility in the basin. The soil erodibility in river Nzoia basin was classified into: Low (0-0.09); Moderate (0.09-0.13); High (0.13-0.19) and Severe (0.19-0.13) levels. The upper and parts of the middle river Nzoia basin with low and moderate erodibility levels are mainly defined by forestland. These areas experience minimal soil erosion due to dense vegetation cover. Areas with high and severe erodibi...
