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 ...
Comparison of β-galactosidase immobilization by entrapment in and adsorption on poly(2-hydroxyethylmethacrylate) membranes
(John Wiley & Sons Ltd, 1997)
beta-Galactosidase was immobilized in/on poly(2-hydroxyethyl methacrylate) (pHEMA) membranes by two different methods: adsorption on Cibacron F3GA derivatized pHEMA membranes (pHEMA-CB), and entrapment in the bulk of the ...
Interpreting the nonideal reverse bias C-V characteristics and importance of the dependence of Schottky barrier height on applied voltage
(Elsevier Science Bv, 1995)
This work presents an attempt related to the charging behaviour of interface states to the nonideal forward bias current-voltage (I-V) and the reverse bias capacitance-voltage (C-V) characteristics of A1-nSi Schottky barrier ...
Radiation effect on polyadenylic acid in aqueous solution
(Pergamon-Elsevier Science Ltd, 1995)
In this study, dilute solution properties of polyadenylic acid (polyA), G values for single strand break formation G(ssb), Arrhenius parameters (25-45 degrees C), the kinetics of strand break in the absence and presence ...
