It is a well known fact that, dual fuel engines at part loads, inevitably suffer lower thermal efficiency, higher carbon monoxide and unburned fuel emission. The work in this paper is to investigate combustion characteristics of a dual fuel (diesel-gas) engine at part loads, using a single zone combustion model with detailed chemical kinetics for combustion of natural gas fuel. The authors deve...

We measure the effects of charge transfer efficiency (CTE) losses on resolved sources in Wide Field and Planetary Camera 2 (WFPC2) images from 1995 to 2008. We compare medium and long exposures of the Hubble Deep Field – North taken with the F606W filter at several epochs against a “truth” mosaic of the field taken with the Advanced Camera for Surveys early in that instrument’s operation. We ad...

Deformation of the material during cyclic expansion extrusion (CEE) is investigated using upper-bound theorem. The analytical approximation of forming loads agrees very well with the FEM results for different amounts of chamber diameter, friction factor and also for lower die angles. However, the difference between analytical and numerical solution increases at higher die angles which are expla...

background: hepatitis activity index (hai) and fibrosing stage are two important findings during the evaluation of liver samples in patients with chronic hepatitis b. the aim of this study was to determine the hai and fibrosing stage in patients with anti-hbe positive chronic hepatitis b. methods: liver biopsy slides of 72 patients were evaluated at the department of pathology in two teaching h...

the current study is focused on strengthening of reinforced concrete (rc) beams using cfrp straps installed in pre-cut grooves. the method which is referred as near surface mounted (nsm) benefits considerable advantages in comparison with the conventional externally bonded reinforcement (ebr) method and provides better normal and shear stress transfer between the frp and concrete substrate. the...
