Magnetic abrasive finishing can be classified as a non-traditional super finishing method for finishing surfaces with different shapes and working materials like flat plates, shafts, bearings parts, screws, tubes and many other mechanical parts that need good surface finishing properties. MAF is effective in polishing, cleaning, deburring and burnishing metal parts. The most important parameter...

PURPOSE To compare the sensory results of patients with low median nerve complete transection and repair, with and without sensory re-education. METHODS We studied 40 patients, aged 20 to 32 years, with low median nerve complete transection. Primary epineural repair using 8-0 single-strand sutures was done in all patients. Hands were immobilized in a splint for 4 weeks, followed by physical t...

In this paper, we describe the influence of vibratory adaptation on vibration perception and its correction method. Vibration strength after change depends on the vibration frequency before change even if the vibration frequency itself does not change. We found that the higher the vibration frequency before change, the weaker the perceived vibration strength. To correct this perception gap, the...

This paper describes a numerically controlled finishing system, the Advanced Deburring and Chamfering System (ADACS). ADACS employs a user friendly, Graphical User Interface (GUI) to off-line program finishing and chamfering edges and prompt the operator for part cutting parameters. Given the operator-designated finishing and chamfering edges, ADACS extracts the features to generate a part fini...

Fused Deposition Modeling (FDM) parts are prone to process-related rough and wavy surfaces with stair-stepping effects whenever the parts produced have sloped or rounded geometries. These stair-stepping effects can be reduced by using a smaller slice height, but complete elimination is not possible. In this paper, FDM parts manufactured with the material ABS-M30 are finished using mass finishin...

This paper presents a MPC (Model Predictive Control) algorithm for MEMS vibratory gyroscopes based on force-balancing control strategy. In the proposed MPC method, using a set of orthonormal basis functions named Laguerre functions, a new prediction and optimization technique is designed. To enhance the capability of proposed MPC method for tracking time-varying reference trajectories, first a ...

Dercum's disease is characterised by pronounced pain in the adipose tissue and a number of associated symptoms and is, in most patients, accompanied by obesity. Postoperative sensory change after liposuction is a well-known side effect, and probably caused by mechanical trauma to the nerves. The aim of this investigation was to find out whether the thermal and sensory sensation changed after li...

Three trials involving 513 exotic crossbred steers were conducted to determine the effect of zeranol implanting in the suckling and growing phases on subsequent feedlot performance and carcass characteristics. Treatments were 1) unimplanted control, 0000; 2) implanted twice in the finishing phase, 00II; 3) implanted in the growing phase and twice in the finishing phase, 0III; 4) implanted in th...

This study was conducted to investigate the influence of dietary rapeseed meal (RSM) on growth performance, blood profiles, nutrient digestibility and economic benefit of growing-finishing pigs. A total of 120 growing pigs ([Yorkshire×Landrace] ×Duroc) with an initial body weight (BW) 29.94±0.06 kg were used in this experiment. Pigs were randomly allotted into 1 of 5 treatments in a randomized ...
