With the ureterorenoscope it is now possible to perform procedures under direct vision that previously had to be undertaken blindly or with the aid of fluoroscopy. The most common use of the ureterorenoscope is for removal of ureteral calculi, particularly those that are in the distal or middle one third of the ureter. The technique of ureteral dilatation and ureteroscopy of the lower ureter vi...

Micro-plate implants are jaw in the form of straight plates. The need for micro-plate Indonesia is quite high. Current fabricated using two machining processes, namely Wire Electrical Discharge Machining (wire-EDM) and micro-milling. These processes one reasons why price market expensive. One way to lower shorten implant manufacturing process. This research develops a process EDM die-sinking ma...

The purpose of this study was to investigate whether application of bipolar galvanic vestibular stimulation (GVS) would influence the common modulation of motor unit discharge rate in bilateral soleus muscles during quiet standing. Soleus motor unit activity was recorded with fine wire electrodes in each leg. Subjects stood, with eyes closed, on two adjacent force platforms to record postural s...

Abstract Usually, when solving the magnetic field distribution of a finite-length straight wire in conducting medium, numerical calculation is required. However, this method has some disadvantages, such as complex calculations and not being conducive to engineering implementation. To solve problem, paper studied attenuation for underwater low-frequency then obtained analytical formula spatial d...

We investigate how a straight skeleton can be used to approximate a motorcycle graph. We explain how to construct a planar straight-line graph G such that the straight skeleton of G reveals the motorcycle graph of M , for every given finite set M of motorcycles. An application of our construction is a proof of the Pcompleteness of the construction problem of straight skeletons of planar straigh...
