The crevice correction is a common type of localized corrosion which costs multibillion dollar losses in many different fields including aerospace, automobile, and building structures. The crevice geometry can easily catch moisture and impurity which accelerates the chemical corrosion. It is one of the dangerous corrosions that can cause sudden failure of the products and involve the human inju...

Coated tool inserts can be considered as the backbone of machining processes due to their wear and heat resistance. However, defects of coating can degrade the integrity of these inserts and the number of these defects should be minimized or eliminated if possible. Recently, the advancement of coating processes and analytical tools open a new era for optimizing the coating tools. First, an over...

Electrochemical coating processes are significantly affected by applied magnetic fields due to the generation of electromagnetic forces. The present research work has been undertaken to study the effect of coating parameters such as current density and alumina concentration on the characteristics of Ni-Al2O3 composite coating under static magnetic field. Ni-Al2O3 composite coating was applied o...

BACKGROUND The relationship between regional and global left ventricular function has not been evaluated. The present study aimed to assess whether regional myocardial contraction and relaxation reflect global left ventricular systolic and early diastolic function, respectively. METHODS AND RESULTS The study involved 45 patients with coronary artery disease (CAD). Conventional echocardiograph...

It is generally believed that sphingomyelin- and cholesterol-enriched microdomains can be isolated as detergent-resistant membranes (DRMs) from plasma membrane and organelle membranes. Here, we describe the isolation and characterization of microdomains from sarcoplasmic reticulum (SR) membranes. These SR-derived detergent-resistant membranes (SR-DRMs) enriched in sphingomyelin and cholesterol ...

Mode selection of guided waves in an elastic steel plate with thick coating layer has been studied here. E€ect of both thick elastic coating and damping of the coating layer on the dispersion and mode shapes has been investigated and modes that are less a€ected by elastic coating and damping have been identi®ed. For modeling the viscoelastic behavior of the coating layer, the standard linear so...

The host response to calcium silicate ceramic coatings is not always favorable because of their high dissolution rates, leading to high pH within the surrounding physiological environment. Recently, a zinc-incorporated calcium silicate-based ceramic Ca2ZnSi2O7 coating, developed on a Ti-6Al-4V substrate using plasma-spray technology, was found to exhibit improved chemical stability and biocompa...

Coating shrinkage upon drying is a phenomenon well known to the paper coating industry where it often causes changes in the final structure of the coating layer, leading to poor results in terms of gloss, light scattering, surface strength, coverage and printability. The aim of this paper is to improve the understanding of coating shrinkage by measuring the forces related to the capillarity, ac...

In the title mol-ecule, C(12)H(13)NO(5)S, the benzisothia-zole ring system is essentially planar (r.m.s. deviation = 0.0169 Å) as is the -C-C(=O)-O-C- sequence of atoms in the vicinity of the acetate group (r.m.s. deviation = 0.0044 Å). The mean plane of these atoms forms a dihedral angle of 88.41 (7)° with the benzisothia-zole ring system. In the crystal, weak C-H⋯O hydrogen bonds involving me...

AIMS The cannabinoid CB1 receptor antagonist, SR141716A, differentially affects the ethanol preference of chronically alcoholized rats when administered during cycles of ethanol exposure and withdrawal. In this study, ethanol preference was investigated in chronically alcoholized rats that underwent regular withdrawal periods during which the brain cannabinoid CB(1) receptor antagonist, SR14171...
