Since fuel must be injected with appropriate pressure and time for accurate performance of diesel engines, then proper function of engine is influenced by accurate function of injector pump. At first total pump was designed by SolidWorks 2012 software. Then the total relationship of rotor, roller, internal cam ring, pole shoe and plunger in injector pump in MF285 tractor and their performance w...

In an estuarine system, the flood tidal wave may become a tidal bore during the early flood tide in a narrow funnelled channel under large tidal ranges. Herein new experiments were conducted in a large flume to investigate breaking tidal bores and the bore roller propagation. The results demonstrated several key features of tidal bores propagating in rectangular channels. The propagation of the...

Two types of computer input devices, a conventional mouse and a roller bar one, were studied in terms of muscular activity in m. trapezius dexter, m. deltoideus anterior dexter and m. extensor digitorum dexter, and comfort rating. Fifteen university students and employees participated in this study. The order of the devices was random. While a task was performed, electromyography (EMG) data wer...

A novel method for large-scale culture of anchorage-dependent cells is described. Culture vessels were constructed by using roller bottles and Pyrex tubing. Parallel glass tubes, equally spaced by silicone rings and inserted into the roller bottles, provided an increased culture area. The roller bottles were fitted with a second opening for medium recirculation. Culture vessels of 1,000-, 4,000...

CONTEXT The identification and evaluation of activities capable of dislodging calyceal renal calculi require a patient surrogate or validated functional pyelocalyceal renal model. OBJECTIVE To evaluate roller coaster facilitation of calyceal renal calculi passage using a functional pyelocalyceal renal model. METHODS A previously described adult ureteroscopy and renoscopy simulator (Ideal An...

A 14 month retrospective study was undertaken to determine the cost implications of the opening of a roller skating rink to the local hospital accident and emergency department (A and E). A total of 398 patients attended following injury at the roller skating rink, of whom 384 were included in the study. The estimated cost of their injuries was determined by the hospital accounts department. Th...

The aim of this study was to investigate the number and types of accidents which occur in connection with roller-skates, and also to find out in which anatomical area the most injuries occurred. During the period 01.02.1995 to 31.08.1996, 389 patients sustained injuries in connection with roller-skates. Fifty-nine percent of all accidents happened on a public road. Out of 389 injuries, 174 sust...

The current BacT/Alert standard aerobic (VA) blood culture bottle was redesigned and designated a nonvented aerobic (NVA) culture bottle; this bottle does not require venting. A total of 3,873 sets of blood samples for culture were obtained from adult patients with suspected bacteremia or fungemia. The NVA bottle showed performance equivalent to that of the VA bottle for recovery and speed of d...
