Aluminium composites are extensively used in several industrial applications. The production of Metal Matrix Composite (MMCs) with varying wt. % reinforcement/s leads to enhancement wear and mechanical behavior. In the present work, TiB2 constant CeO2 particulates were reinforced Al6061 alloy manufacture hybrid Al MMCs by Vortex (Stircasting) technique. Developed hotrolled at 515°C temperature....

Recent studies have shown that chromogenic cephalosporin tests are inferior to disc zone edge tests in detecting penicillinase in Staphylococcus aureus isolates, resulting in a change to CLSI and EUCAST guidelines in 2012. We sought to confirm these findings using Australian isolates and compare the performance of the CLSI and EUCAST methods, which use different disc strengths, penicillin at 10...

This study evaluated the effect of specimens’ design and manufacturing process on microtensile bond strength, internal stress distributions (Finite Element Analysis FEA) and specimens’ integrity by means of Scanning Electron Microscopy (SEM) and Laser Scanning Confocal Microscopy (LCM). Excite was applied to flat enamel surface and a resin composite build-ups were made incrementally with 1-mm i...

Results are shown as a pcrcentage of the first day value under each condition. enzyme, and attempted to determine the level of homocysteine in patients with homocystinuria by our newly developed method for quantifying homoc...

Grade 630 martensitic precipitation hardening stainless steel has a combination of high hardness and strength after suitable heat treatment. The great advantage this grade is that they are usually supplied in the condition treated with solution then aged to achieve sufficient strength. Chosen for research work, AISI samples were subjected salt bath nitriding process. Three chosen shape tapered ...

BACKGROUND Patient demand for tooth colored restorations and desire for minimally invasive restorations have made composites an indispensable part of the restorative process. An important factor affecting the intra-oral performance of composite restorations is bonding. MATERIAL AND METHODS Ninty six freshly extracted molar teeth were collected and occlusal 3mm is removed using a diamond disc ...

Rocks are less resistant to tension than compression or shear. Tension cracks commonly initiate shear failure. The mechanical behavior of layered rocks under has been studied extensively, whereas the tensile still remains uncertain. In this paper, we study effect layer orientation on strength and failure patterns direct indirect through experimental numerical testing (RFPA2D: software Rock Fail...
