Information about the open-access journal Journal of Mechanical Engineering and Sciences in DOAJ. The modified zinc alloys were prepared for different additions of Ni content using the liquid metallurgical technique. Tool steels are commonly used to cut metal materials due to their distinctive hardness, resistance to abrasion and deformation. Journal of Engineering and Applied Sciences provides its' readers basic and transitional knowledge in engineering, technology and applied sciences. The actuator is moved by the difference between forward and backward forces of support point of actuator. These were then characterised under quasi-static loading to obtain hardness and elastic modulus using nano-indentation technique. Upon lowering distance from the surface, static stall takes place at a higher point and a lower angle of attack, respectively. This journal uses The experimental data obtained, such as the yield strength, ultimate strength and S-N curve were used as the input parameters in ANSYS Workbench 16.1. American Journal of Mechanical Engineering.2020, 8(4), 144-153.DOI: 10.12691/ajme-8-4-1 Pub. The results show the λ1 and λ2 change inversely with solidification parameters except for tSL. The result showed that compound effectively suppressed corrosion by the appearance of an improved surface structure of carbon steel with increasing concentration of [BMIM][MOPS]. In this study the performance and emission characteristics of spark ignition genset engine fueled with gasoline and diethyl ether (DEE) blends are carried out. The inhibition efficiency increases with increase in the concentration of [BMIM][MOPS]. The research of microstructure showed the reason for increased joint strength and microhardness. Different rotational speeds,1000 and 1800 rpm and traverse speed 10 mm \ min was examined. In this paper, a framework incorporating the fuzzy analytic hierarchy process (FAHP) with extent analysis with the analytic hierarchy process (AHP) has been proposed in order to overcome the problems of consistent judgement in FAHP and solve conventional AHP problems in dealing with subjective judgement, especially in prioritizing customer requirements. The objective of this study is to evaluate the kinetic and mass transfer parameters in a CO2 absorption process using monoethanolamine (MEA), 2-(methylamino)ethanol (MMEA), and 2-(ethylamino)ethanol (EMEA) as absorbents. The objective of this study was to investigate and predict flow and leaflet phenomena via a simple 2D mitral valve model based on the critical parameter of blood. The bio-active and biological affinity with bony tissue effect of hydroxyapatite (HA) marks as a chosen material for implants application. The results indicated that the PFAC is very effective for RBBR adsorption from aqueous solution.

The highest thermal enhancement factor is achieved for the pitch value of 320mm and an air gap height of 3mm at Re=6000. The digitized footprint analysis exhibited a non-symmetrical (ellipse-shaped) footprint where the footprints showed plastic anisotropic behaviour and localized plastic strain in such recycled material.
