asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...

In the present study, the transient stress distribution caused by a break in the fibers of an adhesive bonding is investigated. Transient stress is a dynamic response of the system to any discontinuity in the fibers from detachment time till their equilibrium state (or steady state). To derive the governing dynamic equilibrium equations shear lag model is used. Here, it is assumed that the tens...

The goal of the current study is to determine the optimal level of advertising beyond which advertising expenditure will not be justified by revenues. To achieve the goal first different types of media were rated by experts as to the degree of their importance. Then data ware collected by interviewing the managers and reviewing different media resources. The collected data were then analyze...

The thermal properties of wood in the green state have been determined by the transient plane source (TPS) technique. Data are presented on thermal conductivity ( λ ), heat capacity ( C ), and thermal diffusivity ( κ ) at moisture contents (MCs) above the fiber saturation point, which are based on measurements using the HotDisk ® apparatus. Four wood species (Douglas fir, beech, birch, and spru...
