INTRODUCTION Arthritis induces joint erosions and skeletal bone fragility. OBJECTIVES The main goal of this work was to analyze the early arthritis induced events at bone architecture and mechanical properties at tissue level. METHODS Eighty-eight Wistar rats were randomly housed in experimental groups, as follows: adjuvant induced arthritis (AIA) (N = 47) and a control healthy group (N = 4...

The selective laser melting (SLM) of aluminium alloys is of great current interest at both the industrial and research levels. Aluminium poses a challenge to SLM compared with other candidate materials, such as titanium alloys, stainless steels, and nickel-based alloys, because of its high thermal diffusivity and low infrared absorptivity and tendency to result in relatively porous parts. Howev...

The usage of powder metallurgy aluminium compacts in lieu of ferrous components in automotives helps to lower vehicle weight. The major drawback in the commercially available press sintered aluminium alloy is porosity which is mainly dependent on the powder metallurgical process parameters such as compaction pressure, sintering temperature and cooling rate after sintering. In this paper the eff...

Although high carbon martensitic steels are well known for their industrial utility in high abrasion and extreme operating environments, due to their hardness and strength, the compressive stability of their retained austenite, and the implications for the steels' performance and potential uses, is not well understood. This article describes the first investigation at both the macro and nano sc...

Streptococcus mutans is a primary etiological agent of dental caries. Farnesol, as a potential antimicrobial agent, inhibits the development ofS. mutans biofilm. In this study, we hypothesized that farnesol inhibits caries development in vitro and interferes with biofilm formation by regulating virulence-associated gene expression. The inhibitory effects of farnesol to S. mutans biofilms on ena...

In many investigations, large number of process, or design parameters that are initially thought to affect the outcomes or outputs may not really have statistical significant influence on them. Screening experiments are used to identify the key parameters (factors) that significantly affect these outcomes. In this investigation, Plackett-Burman screening design was used to identify the factors ...

Current experimental investigation deals with the effects of asymmetrical rolling parameters on the inhomogeneity, microstructure, mechanical, and geometrical properties of rolled brass wire. Toward this end, a roll machine with three different roll radii ratios was set up. The asymmetrical conditions are arranged using three different sets of rolls with different diameters that result into dif...

Friction stir welding is a solid state joining process first used for welding of Aluminum and its alloys, is now employed for welding of polymers and composite materials. Polypropylene (pp) is one of polymer materials used in many applications due to its good performance, high strength to weight ratio and excellent processing properties, its application is limited due to its weak abrasive prope...

This report describes a novel way to generate a highly effective hydrophobic cement surface via a carbonation route using sodium stearate. Carbonation reaction was carried out at different temperatures to investigate the hydrophobicity and morphology of the calcium carbonate formed with this process. With increasing temperatures, the particles changed from irregular shapes to more uniform rod-l...

Abstract — Fe2O3 substituted 45S5 bioactive glasses were prepared. Glass derived Bioactive Glass ceramics were obtained through controlled crystallization of bioactive glasses. Nucleation and crystallization regimes were determined by the parameters obtained from differential thermal analysis (DTA) of bioactive glasses. The formed crystalline phases in bioactive glass ceramics were identified u...
