landfill and incineration are two common methods mostly used for disposal of huge quantities of solid wastes. the bioconversion ability of earthworms in vermicomposting process of organic waste in different types of bedding materials was investigated to produce more valuable products as an economical and effective alternate method for solid waste management. in this work organic waste (obtained...

BACKGROUND Recently, van Walraven developed a weighted summary score (VW) based on the 30 comorbidities from the Elixhauser comorbidity system. One of the 30 comorbidities, cardiac arrhythmia, is currently excluded as a comorbidity indicator in administrative datasets such as the Nationwide Inpatient Sample (NIS), prompting us to examine the validity of the VW score and its use in the NIS. ME...

We investigate the effect of curvature on energy and stability domain wall configurations in curved cylindrical nanotubes nanowires. use micromagnetic simulations to calculate phase diagram for transverse (TW) vortex (VW) states tubes, finding lower configuration metastability region where both types walls can exist. The introduction shifts range which TW is ground state higher diameters increa...

BACKGROUND AND PURPOSE The aim of the study was to determine the effects of thromboembolism and mechanical thrombectomy on the vessel wall magnetic resonance imaging (VW-MRI) appearance of the intracranial arterial wall. METHODS This was a cross-sectional study of consecutive patients with acute intracranial arterial occlusion who underwent high-resolution contrast-enhanced VW-MRI within days...

Proof. A triangulation is a plane graph in which every face is bounded by three edges. Edges can be added to a plane graph to obtain a plane triangulation. Thus it suffices to prove the theorem for plane triangulations G. We proceed by induction on |V (G)|. The base case with |V (G)| = 3 is trivial. Now suppose that |V (G)| ≥ 4. A separating triangle of G is a 3-cycle that contains a vertex in ...

The most commonly used method for biodiesel preparation is via transesterification of vegetable oil using alkaline catalysts. Biodiesel yield and oil conversion are affected by operating conditions including the catalyst formulation and concentration. Application of alkaline catalysts can also lead to undesired soap formation. This study evaluated the alkaline catalyst effects on biodiesel yiel...

Supercritical Water Gasification is a promising approach to convert biogenic residues such as cattle manure, fruit/vegetable waste, and cheese whey into valuable biofuels.

Biodiesel has attracted increasing interest and has proved to be a good substitute for fossil-based fuels due to its environmental advantages and availability from renewable resources such as refined and waste vegetable oils. Several studies have shown that biodiesel is a better fuel than the fossil-derived diesel in terms of engine performance, emissions reduction, lubricity and environmental ...

The acute waste management problems, coupled with the proliferation of small scale industries in many developing countries, make low quality water treatment before use inevitable in the long run. These industries have the potential to discharge effluent containing chemicals and heavy metals into the environment. The indiscriminative use of pharmaceutical products by households in many of these ...
