In this study, functionally graded Ni-Al2O3 composite coating (FGN-A) has been produced from nickel Watt’s bath containing different concentrations of Al2O3 particles. For this, different composite coatings were electroplated in the same bath with different particles concentration to find the optimum concentration of particles in which the maximum content with uniform distribution of Al2O3 part...

a total of 68385 live pin-worm eggs from adhesive scotch tape were exposed to different detergent powders in under to compare method of detergent washing clothes with the boiling method for the control of family enterobiasis. results show that: a) 80.4-100 percent of eggs are destroyed after hatching within 6-8 hours of exposure to 0.25 gr% detergent at 10-250c. exposure for less than 6 hours h...

UNLABELLED Pin tract inflammation and/or infection are common with the use of external fixation devices. Pin sites need to be managed to help prevent complications. There are a variety of regimens proposed for pin care in the literature. The authors present an efficient and simplified approach for addressing pin care protocol using cord locks with the use of compression sponges for external fix...

The present study aims to the wear behaviour of Mg reinforced with boron nitride nanocomposite. dry sliding (0.5 wt.%) is reviewed by following ASTM standards G99, i.e., on pin-on-disk test apparatus. Three parameters, namely load, speed, and distance, were considered in this study. experiments for rate have been conducted as per G99. obtained predicted ANN toolbox Matlab R2021a using Levenberg...

The aim of the current work was to analyse impact salt bath nitriding on behavior tribological characteristics and surface microstructures AISI 316L stainless steels. Nitriding carried out at 580°C for 10 h. tribological, structural before after compared. microstructures, characteristics, as well its hardness, were investigated using optical microscopy (OM), X-ray diffractometer (XRD), profilom...

STUDY DESIGN A retrospective analysis of halo device associated morbidity over a 4-year period. PURPOSE To assess the impact of a new pin care regimen on halo pin site related morbidity. OVERVIEW OF LITERATURE Halo orthosis treatment still has a role in cervical spine pathology, despite increasing possibilities of open surgical treatment. Published figures for pin site infection range from ...

The potential of graphene as a solid lubricant in sliding Ag-based electrical contacts has been investigated. Graphene was easily and quickly deposited by evaporating a few droplets of a commercial graphene solution in air. The addition of graphene reduced the friction coefficient in an Ag/Ag contact with a factor of *10. The lubricating effect was maintained for more than 150,000 cycles in a p...

Nickel chromium (NiCr) powders with different titanium diboride (TiB2) additions (20, 40 and 60 wt %) were prepared with a mechanical alloying method and then sprayed using an air plasma spraying technology. The microstructure and phase composite of the powders and the cross-sections of deposited coatings were analyzed with a scanning electronic microscope and X-ray diffraction. The tribologica...
