Examination of static and 50 Hz electric field effects on tissues by using a hybrid genetic algorithm and neural network
(Wiley, 2008)
The effects of electric fields on tissue are the main subject of many investigations. The importance of this subject comes from the electrical properties of the cell membrane and its sensitivity to changes in electrical ...
Experimental investigation of the effect of grading characteristics on the liquefaction resistance of various graded sands
(Elsevier Science Bv, 2008)
The liquefaction susceptibility of various graded fine to medium saturated sands are evaluated by stress controlled cyclic triaxial laboratory tests. Cyclic triaxial tests are performed on reconstituted specimens having ...
Serum haptoglobin levels in ocular Behcet disease and acute phase proteins in the course of Behcet disease
(Wichtig Editore, 2008)
PURPOSE. Changes in concentrations of acute phase proteins in the serum of patients might be significant in the pathogenesis of Behcet disease. This report investigates the association between ocular disease activity and ...
Sea water effect on pinned joint glass fibre composite materials
(Elsevier Sci Ltd, 2008)
The effect of sea water on the bearing strength behavior of the woven glass fibre composite has been investigated experimentally. The ratio of the edge distance to the pin diameter (E/D), and the ratio of the specimen width ...
A bicriteria flowshop scheduling with a learning effect
(Elsevier Science Inc, 2008)
In many situations, a worker's ability improves as a result of repeating the same or similar tasks; this phenomenon is known as the learning effect. In this paper the learning effect is considered in a two-machine flowshop. ...
Optimal buffer allocation in finite closed networks with multiple servers
(Pergamon-Elsevier Science Ltd, 2008)
In this study, we present an optimal buffer allocation procedure for closed queueing networks with finite buffers. The performance measures are evaluated using the expanded mean value analysis, and the solution procedure ...
Catalase adsorption onto cibacron blue F3GA and Fe(III)derivatized poly(hydroxyethyl methacrylate) membranes and application to a continuous system
(Elsevier Science Bv, 1997)
Poly(2-hydroxyethyl methacrylate) (poly(HEMA)) membranes were prepared by W-initiated photopolymerization of HEMA in the presence of an initiator (a-a'-azobisisobutyronitrile, AIBN). An affinity dye, i.e. Cibacron Blue ...
Performance of engineered cementitious composites under drop-weight impact: Effect of different mixture parameters
(Ernst & Sohn, 2019)
Current research focuses on the experimental and numerical determination of impact performance of engineered cementitious composites (ECC). Performance assessment of ECC beams with different mixture parameters was made. ...
Covalent immobilization of α-amylase onto pHEMA microspheres: preparation and application to fixed bed reactor
(Elsevier Sci Ltd, 1995)
Microspheres of poly(2-hydroxyethyl methacrylate) with and without cross-linker were prepared by suspension polymerization. As the amount of cross-linker increased, the equilibrium water content, enzyme loading, immobilization ...
Graft copolymerization of n-vinyl-2-pyrrolidone on dimethyl sulfoxide pretreated poly(ethylene terephthalate) films using azobisisobutyronitrile initiator
(John Wiley & Sons Inc, 1997)
Poly(ethylene terephthalate) (PET) films were grafted with n-vinyl-2-pyrrolidone (n-VP) using an azobisisobutyronitrile (AIBN) initiator. Films were pretreated in dimethyl sulfoxide (DMSO) for 1 h at 140 degrees C before ...
