The effects of ion bombardment of ultra-high molecular weight polyethylene
(
Elsevier
, 2006 , Article)
Ion bombardment is a suitable tool to improve tribological properties of polymers. In this study UHMWPE samples were bombarded with 130keV He ions to the fluences ranging from 1×1014 to 2×1016cm−2. RBS and NRA techniques ...
Surface layer modification of ion bombarded HDPE
(
Elsevier
, 2004 , Article)
Press-moulded, high density polyethylene (HDPE) samples were subjected to ion bombardment and effects of the modification studied. He+ ions of energy 100 keV or Ar+ ions of energy 130 keV were applied in the range of dose ...
Temperature and electric field effects on the dielectric dispersion of modified polyvinyl chloride
(
Elsevier
, 2003 , Article)
The effect of electric field on the dielectric dispersion of modified polyvinyl chloride (PVC) has been investigated. The applied direct current (DC) field strength was ranging from 0 to 104 V cm−1. The complex permitivity ...
A simple method for finding empirical likelihood type intervals for the ROC curve
(
Wayne State University
, 2007 , Article)
Interval estimation of the ROC curve is considered using the empirical likelihood techniques. Suggested is a procedure that is very simple computationally and avoids the constrained optimization problems usually faced with ...
Reduction kinetics of ceria surface by hydrogen
(
Elsevier
, 2004 , Article)
Sintered ceria pellets of porosity 16.4% and density 5.99gcm−3 were treated in a hydrogen flow at 1atm and various temperatures. The electrical conductivity was measured in situ while hydrogen gas was flowing over the CeO2. ...
Reduction kinetics of ceria surface by hydrogen
(
Wiley Periodicals, Inc.
, 2004 , Article)
Powdered cerium dioxide (ceria, CeO2) as compressed, sintered pellets, of porosity 16.4% and density 5.99 g cm−3, were treated in hydrogen flow at 1 atm and various temperatures to effect reduction. The electrical conductivity ...
Phylogenetic analyses of peanut resistance gene candidates and screening of different genotypes for polymorphic markers
(
Elsevier
, 2009 , Article)
The nucleotide-binding-site-leucine-rich-repeat (NBS–LRR)-encoding gene family has attracted much research interest because approximately 75% of the plant disease resistance genes that have been cloned to date are from ...
