Without rotating instruments, for example diamond-coated drills with a core made of stainless steel, the dental routine would be unimaginable, since these are used in almost every activity and thus indispensable professional practice. Unfortunately, such release Nickel particles to high content into cooling water drill. Values up 1.3 mg/l were found by ICP – OES drillers which is course also tr...

Field pennycress (Thlaspi arvense L.) (PC) and winter camelina [Camelina sativa (L.) Crantz] (WC) have the potential to provide ecosystem services economic incentives when adopted as an oilseed cover crops in corn (Zea mays L.)–soybean [Glycine max Merr.] rotations. However, PC WC establishment yield northern Corn Belt their subsequent impact on row are not well known. This study was conducted ...

In order to study the wear resistance and corrosion of a composite material with Fe316L substrate Co-Cr-WC coating, Co-Cr alloy coatings different mass fractions WC (hard tungsten carbide) were prepared on by laser cladding technology. The phase composition, microstructure element distribution analyzed X-ray diffraction (XRD), scanning electron microscopy (SEM) energy dispersive spectroscopy (E...

White Carneau (WC) pigeons are susceptible to the development of aortic atherosclerosis, whereas Show Racer (SR) pigeons are resistant, even though there are no differences in the known risk factors, including plasma cholesterol levels, lipoproteins, blood pressure, etc. Although this suggests that the difference in atherosclerosis susceptibility between WC and SR pigeons may be mediated at the...

The effect of coherency WC/Co phase boundaries on the fracture toughness of the nanocrystalline WC-Co cemented carbides is studied by MD simulation method. The simulation results show that the nanocrystalline WC-Co cemented carbides with coherency WC/Co phase boundaries has higher fracture toughness than that without coherency WC/Co phase boundaries. Moreover, the mechanism of why coherency WC/...

conclusions the fluoride content of drinking water in reservoirs and at homes was below the optimal level in mariwan. no differences were observed from the standard levels in behbahan. there were no differences in fluoride content of water in reservoirs and in home pipelines, indicating no tangible changes in fluoride content from the reservoirs to the homes. in neither of the towns was severe ...

Dicamba plus glyphosate tank mixture have been largely adopted for postemergence weed control after the development of dicamba-tolerant crops. Ammonium sulfate is commonly used as water conditioner (WC) to increase efficacy, but its use restricted dicamba herbicides. The non-AMS and other adjuvants could be a way optimize efficacy this while mitigating herbicide off-target movement. objective s...

AIM To compare the maximal power output (MPO) of subjects presenting a central adiposity to those of controls and to study the links between plasma leptin or indices of insulin sensitivity (QUICKI) and physical fitness (PF). METHODS MPO was determined for 169 middle-aged men divided into two groups according to waist circumference (WC- < 94 cm, WC+ ≥ 94 cm) each subdivided in two subgroups wi...
