BACKGROUND High tension in an anterior cruciate ligament graft adversely affects both the graft and the knee; however, it is unknown why high graft tension in flexion occurs in association with a posterior femoral tunnel. The purpose of the present study was to determine the effect of the angle of the femoral and tibial tunnels in the coronal plane and incremental excision of the posterior cruc...

Overexposure to airborne respirable crystalline silica (or quartz) dust can cause serious or fatal respiratory disease. In particular, some of the most severe cases of silicosis have been observed in surface mine rock drillers. A voluntary lung screening study conducted on surface coal mine workers in Pennsylvania concluded that the incidence rate of silicosis is directly related to age and yea...

Lumped Parameter Model is well known in solving high frequency signal propagation in high voltage transformer windings. At Southampton University, the modelling technique has been improvised and employed to solve partial discharge (PD) problem occurred within deep inside transformer windings. Firstly, a lumped capacitive parameter model was considered and secondly a transmission line lumped par...

The novelty of the present study is that it investigates effect propeller shaft deflection, caused by self-weight and interfacial mixed forces, on fluid–solid–heat (FSH) coupling performance water lubricated rubber stern bearing (WLRSB). In FSH model, generalized average Reynolds equation Kogut–Etsion asperity contact model are used to determine hydrodynamic elastic–plastic behaviors WLRSB. the...

Backhoe merupakan salah satu jenis excavator yang banyak digunakan pada aplikasi pertanian dan konstruksi sebagai peralatan penggali, pengangkat pemuat. Lokasi kerja backhoe berpasir berbatu akan mempercepat keausan komponen undercarriage utamanya front idler, yaitu shaft. Data ada shaft selalu mengalami kerusakan dengan waktu penggunaan kurang dari setahun. Untuk itu penulis tertarik untuk mel...

Partial discharge (PD) may occur in a transformer winding due to ageing processes, operational over stressing or defects introduced during manufacture. The presence of PD does not necessarily indicate imminent failure of the transformer but it will lead to serious degradation and ageing mechanisms which can be considered as a precursor of transformer failure. A necessary step is required in ord...
