Objective: Obesity and cardiovascular disease (CVD) are closely related and have become increasingly prevalent in Korea. Asians are more prone to obesity-related co-morbidities than Caucasians, even at lower body mass index (BMI) and/or smaller waist circumference (WC) values. Nevertheless, little is known regarding the association of WC with the risk of CVD in non-Caucasian populations. The au...

Abstract To investigate the corrosion behavior of WC–Co composite coating, plasma transferred arc (PTA) welding was applied to prepare coating on hull steel EH40 for achieving good metallurgical bonding. The phases coatings were mainly composed WC particles, solid solution γ-Co, Fe 3 Ni 2 , SiO and Mo C. After electrochemical test, it can be concluded that Co-based with 45% content has better r...

Abrasive wear behaviour of WC-Co and Fe/Cu-based nanostructured coatings has been investigated under dry slurry conditions in this study. The retention coating constituents was confirmed together with the formation various metallic ceramic phases. rate one order lower than that micro-structured both conditions. Relatively higher abrasion resistance such compare to reference material because com...

It was shown earlier that immune responses against cholera toxin (CT) as well as Vibrio cholerae lipopolysaccharide (LPS) or whole bacterial cells (WC) were protective and that these different antibody specificities co-operated synergistically for protection against experimental cholera. Similarly, antibodies against the heat-labile toxin (LT) and major colonization factors (CFs) of enterotoxin...

The actual task of this work is to obtain homogeneous hard alloys with fine carbide grains, combining high hardness and strength. Studies were carried out establish the most favorable phase compositions rational technical methodology for their production. In research work, a nanostructured WC-TiC-Co powder charge was obtained by mechanochemical synthesis. Nanosized WC nanopowder precipitated Co...

The current research explores the influence of multi-asperity abrasive particles engagement on multiphase materials. WC-Co (WC-15.6% Co) and NbC-cermet (NbC-12% Ni–10% Mo 2 C) hard materials were tested using a scale down single point scratch tester. Multi-asperity patterns produced by implying multiple scratches hardmetal surface parallel repeated sliding. Superimposition interactions has been...
