PURPOSE To evaluate the size and shape of commercially available polyvinyl alcohol (PVA) particles and to determine whether they change in size when suspended in nonionic contrast and in a solution of nonionic contrast and absolute alcohol. METHODS The two-dimensional area and the long and short axis of PVA particles from several different vendors were measured using a light microscope attach...
the studies report the synthesis of novel graft copolymer of oatmeal. polymethyl methacrylate grafting was carried out on oatmeal backbone via ‘microwave assisted’ approach. the graft copolymers were optimized by varying monomer and can concentration. the synthesized graft copolymers were characterized by intrinsic viscosity, ftir, tga, sem, elemental analysis, number average molecular weight a...

Electronic cash (E-cash) is the digital counterpart of cash payment. They allow users to spend anonymously unless they “double spend” their electronic coins. However, it is not possible to prevent users from misbehaving under some other subjective definitions of misbehavior, such as money laundering. One solution is to incorporate a trusted third party (TTP), which, upon complaint, uses its pow...
BACKGROUND The dispersion-aggregation behaviors of suspended colloids in rivers and estuaries are affected by the compositions of suspended materials (i.e., clay minerals vs. organic macromolecules) and salinity. Laboratory experiments were conducted to investigate the dispersion and aggregation mechanisms of suspended particles under simulated river and estuarine conditions. The average hydrod...
Transformer oil is one of the most important materials which are used in electrical and transformer industrial. The main function is protection and insulation of transformer core components, as well as heat transfer from its core to environment. Improving the performance of this material has been one of the researchers' concerns. The effect of different nanoparticle on the electrical breakdown ...
in new management approaches, in the organizations with inflexible structure, existing of red tapes and interruptions caused by limitations and also non-compliance with environmental changes, create demotivation among staff. with regard to the influence of job motivational potential and its relationship to the type of organizational structure( enabling and dissuasive), the goal of this research...
The operation of an interferometer for gravitational waves detection requires sophisticated feedback controls in many parts of the apparatus. The aim of this lecture is to introduce the types of problems to be faced in this line of research. The attention is focused on the inertial damping of the test mass suspension of the VIRGO interferometer (the superattenuator): it is a multidimensional lo...
