Floating porous ceramics have been successfully fabricated using protein foaming-consolidation method. Alumina powder and yolk as the pore creator were mixed while stirring and the resulting slips were poured into cylindrical shaped molds followed by drying for foaming-consolidation process. The dried green bodies were then burned at 600 8C for 1 h

Nickel based super alloy or Inconel 718 is known as heat resistant alloys which they are primarily used in gas turbine, steam turbine component and aircraft engine component construction [1]. Inconel 718 attained several unique combinations of properties like strength at elevated temperature, resistance to chemical degradation and wear resistance [

The use of advanced computer-based systems for the selection of optimum conditions of mechanical components during process planning becomes essential for today’s complex products. Computer aided manufacturing (CAM) has widely been implemented to obtain more accurate machining data and to ensure that optimum production is achieved. Machinability o

A high cutting temperature inherently characterizes high production machining. Such a high cutting temperature adversely effects tool life, dimensional and form accuracy and surface integrity of the product. Currently, an effort is being made to control this problem by reducing heat from the cutting zone through proper selection of machining parame

A burr is a raised edge or small pieces of material remaining attached to a workpiece after it has undergone machining. The Burr, Edge and Surface Technology (BEST) Division, the Society of Manufacturing Engineers defines a burr as “an undesirable projection of material that results from cutting, forming, blanking or shearing operation [1]. The f

Juxtaposing needs analysis with rights analysis has been an alternative approach in employing needs analysis in EAP (Benesch, 1999, 2001). On a different note, Hyland (2006) proposes that EAP can be related to three areas of controversies: 1) the two approaches in EAP – EGAP and ESAP; 2) the approaches in the teaching of student writing – the s

The understanding of ergonomics is a vital competency for all peripheral nerve block operators. The essence of physical ergonomics for peripheral nerve block procedures can be summarised into three significant components: brain, musculoskeletal and needling. The first component includes strategies to optimise visuospatial neuroprocessing using equi

Inconel 718 is widely used in the aviation, space, navigation and shipping industries because of its outstanding properties. The very mechanical characteristics that give this alloy the highly valued properties also make it one of the most difficult-to-machine aerospace materials. Due to the hardness of nickel-based super-alloys, such as Inconel 71
