Total and high molecular weight adiponectin in patients with coronary artery disease
(
Wolters Kluwer Health
, 2009 , Article)
BACKGROUND: Serum adiponectin inversely correlates with the extent of coronary artery disease (CAD). OBJECTIVES: To investigate the clinical significance of measuring high molecular weight (HMW) adiponectin in addition to ...
Hypoadiponectinemia in obese and diabetic subjects in the State of Qatar
(
Karger
, 2008 , Article)
Background: Obesity is commonly associated with insulin resistance (IR), and is a common cause of type 2 diabetes. Adiponectin is an adipose tissue protein that enhances insulin sensitivity and has anti-atherogenic properties. ...
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 ...
Ion beam modification of surface properties of polyethylene
(
Elsevier
, 2003 , Conference Paper)
Improvement of polymer tribological properties is an essential issue for their application when used as parts of machines or artificial human joints. Ion implantation is a very promising technique in this respect. This ...
Mechanical and thermal properties of gamma-ray irradiated polyethylene blends
(
Elsevier
, 2003 , Conference Paper)
In this work, the results obtained by gamma-ray irradiation of polyethylene (PE) blends are presented. The blends were produced by injection molding at 220°C with different compositional ratios, i.e. 100/0, 15/85, 25/75, ...
Compositional transformations in ion implanted polymers
(
Elsevier
, 2005 , Conference Paper)
Changes of surface layer composition produced by ion bombardment of polyethylene and polypropylene samples were studied. These materials are under consideration for load bearing surfaces in biological and technical ...
Modeling and optimization of biogas production from a waste digester using artificial neural network and genetic algorithm
(
Elsevier B.V.
, 2009 , Article)
Artificial neural networks (ANNs) and genetic algorithms (GA) are considered among the latest tools that are used to solve complicated problems that cannot be solved by conventional solutions. The present study utilizes ...
A Property Based Approach for Simultaneous Process and Molecular Design
(
Elsevier B.V.
, 2009 , Article)
In this work, property clustering techniques and group contribution methods are combined to enable simultaneous consideration of process performance requirements and molecular property constraints. Using this methodology, ...
