Shape memory alloys are kind of smart materials, which have distinctive properties and are superior in compare with other alloys. Severe reactions to thermodynamic and mechanical parameters and ability to return to their original shape make these alloys distinctive from other alloy regarding machining ability. Since these alloys have a very useful application in various fields such as aerospace...

INTRODUCTION Metal implants placed during fracture surgery are often removed for various reasons (i.e. pain, prominent material, patients request). The removal of implants is considered a 'clean' procedure and as low risk surgery. The incidence of wound infections following implant removal has received little attention in the literature. The aim of the current study was to assess the incidence ...

Abrasive water jet machining (AWJM) is one of the non conventional machining process for difficult to cut brittle, hard and thin materials. The process parameters which are mainly influence the quality of machining in AWJM are water pressure, stand-off distance, nozzle diameter, traverse speed, abrasive flow rate and abrasive size. This is an environment friendly and relatively inexpensive proc...

Every day scientists are developing new materials and for each new material, we need economical and efficient machining. Turning process is the one of the methods to remove material from cylindrical and non-cylindrical parts. Stainless steel is a widely used material in day to day applications. This paper deals with the optimization of turning process by the effects of machining parameters appl...

In the present paper, an axisymmetric two-dimensional model for powder mixed electric discharge machining (PMEDM) has been developed using the finite element method (FEM). The model utilizes the several important aspects such as temperaturesensitive material properties, shape and size of heat source (Gaussian heat distribution), percentage distribution of heat among tool, workpiece and dielectr...

Introduction. Azithromycin is among the broad-spectrum antibiotics that is widely available in various environmental systems and could have destructive effects on the ecosystem and human health due to its bacterial resistance. In this study, removal of azithromycin from wastewater using an advanced oxidation process of ultraviolet light with and without persulfate was investigated and effective...

A biomass waste, rice husk, was inspected by thermoanalytical investigation to evaluate its capability as an adsorbent medium for tar removal. The pyrolysis process has been applied to the rice husk material at different temperatures 600, 800 and 1000 °C with 20 °C/min heating rate, to investigate two topics: (1) influence of temperature on characterization of rice husk char and; (2) adsorption...

Electrical discharge machining process, is one of the most widely used methods for machining, the electrically conductive parts. In this way the tool is not in contact with the workpiece and the hardness of workpiece does not affect the machining speed. In Electrical Discharge Machining process, selection of the correct machining parameters are effective in final cost and the quality of the pro...

The aim of this research work is to evaluate the effects of coolant including nano- powder material for the cooling purpose in milling process and comparing the results with the conventional coolant. Generation heat and weak heat transfer reduces the tool life and also deteriorate surface roughness during milling operation. To overcome this problem, it is necessary to use coolant for cooling as...

Background and Objectives : Ethylbenzene (EB) is a dangerously organic compound which the presence of this pollutant in water solutions can be considered as an environmental and public health hazard. In this study, nano magnetic particles (Fe 3 O 4 ) were used as an adsorbent to remove ethylbenzene from aqueous solutions. Methods : The specification of the adsorbent was investigated by transmis...
