A sustainable, heat-resistant and flame-retardant cellulose-based composite nonwoven has been successfully fabricated and explored its potential application for promising separator of high-performance lithium ion battery. It was demonstrated that this flame-retardant cellulose-based composite separator possessed good flame retardancy, superior heat tolerance and proper mechanical strength. As c...
The performance of the electric submersible pump (ESP) significantly affected by Gas Void Fraction (GVF). Thus, using of a Rotary Gas Separator (RGS) is a suitable solution for this issue. The performance of the RGS is function of different parameters such as geometry of impeller, rotating speed, boundary conditions, media viscosity and GVF. In this study, the influences of GVF, viscosity, and ...
The rapid development of industry increases the demand and importance chromium. In this study, beneficiation possibilities representative chromite ore taken from Tokat Province with a laboratory type jig, spiral concentrator, shaking table multi gravity separator (MGS) were investigated. Appropriate particle size fractions fed into each device. Experimental studies shown as flow chart. gave bes...
We prove separator theorems in which the size of the separator is minimized with respect to non-negative vertex costs. We show that for any planar graph G there exists a vertex separator of total vertex cost at most c q P v2V (G) (cost(v)) 2 and that this bound is optimal within a constant factor. Moreover such a separator can be found in linear time. This theorem implies a variety of other sep...
We address the problem of nding a minimal separator in a di rected acyclic graph DAG namely nding a set Z of nodes that d separates a given pair of nodes such that no proper subset of Z d separates that pair We analyze several versions of this problem and o er polynomial algorithms for each These include nding a minimal separator from a restricted set of nodes nding a minimum cost separator and...
"Pre-separator plus1D2D cyclone" and "pre-separator plus 1D3D cyclone" systems were tested with ground gin trash, which contains 10.35% lint fiber and 5.49% fine dust (less than 100 μm). Test results indicate that the pre-separator collected gin trash at over 97% collection efficiency. There were no significant differences in emission concentrations and overall collection efficiencies from thes...
Separators are used to protect cathodes from biofouling and to avoid electrode short-circuiting, but they can adversely affect microbial fuel cell (MFC) performance. A spray method was used to apply a polyvinyl alcohol (PVA) separator to the cathode. Power densities were unaffected by the PVA separator (339±29mW/m(2)), compared to a control lacking a separator in a low conductivity solution (1m...
