Aim of the present study was to describe the muscle fibre type composition and body composition of well-trained hammer throwers. Six experienced hammer throwers underwent the following measurements: one repetition maximum in squat, snatch, and clean, standing broad jump, backward overhead shot throw and the hammer throw. Dual x-ray absorptiometry was used for body composition analysis. Fibre ty...

In this paper by using numerical evaluation the effect of balancing drupes of water hammer on tunnels lining is considered. In case of not arrangment of these reservoirs, the tunnel lining will be damaged of cyclic powers of water hammer. In this research, function of balancing reservoir of water hammer on cover of tunnels to the barriers’ turbine is simulated by numerical methods and Plaxis 3D...

sustainability of water supply networks should be based on the risks of water hammer phenomenon. the purpose of this study is to provide a new approach to the analysis of water hammer phenomenon in the water supply network. by conventional methods, the damage because of water hammer is estimated based on the maximum pressure at nodes. however, during this phenomenon continuation and changing of...

Vibratory installation of piles and casings can be extremely economical and therefore the contractors’ preferred method of pile driving. Compared to impact pile driving it also has the advantage of reduced noise pollution. Unfortunately, this installation method is still fraught with uncertainties. The foremost question is driveability and equally important is the question of bearing capacity o...

This paper describes a method and a system for visualizing a virtual tunnel through an existing geologic formation and a method for the generation of a camera animation along the tunnel axis. The tunnel is built from geologic data coming from vertical sample drills from the mountain top along the selected tunnel axis. Its wire frame model is then edited by a geologist and image information of t...

CLINICAL SCENARIO: There are two primary approaches to cognitive rehabilitation for adults with traumatic brain injury (TBI), the remedial approach (deficit-specific skills training such as table-top activities and repetitive drills) and the adaptive or compensatory approach (adapting tasks, routines and environments). A primary goal of occupational therapy (OT) in cognitive rehabilitation is t...

Image registration is the process of aligning separate images into a common reference frame so that they can be compared visually or statistically. In order for this alignment to be accurate and correct it is important to identify the correct anatomical correspondences between different subjects. We propose a new approach for a feature-based, inter-subject deformable image registration method u...

the study deals with noise problems associated with the use of air-turbine drills in dental practice. noise level measurements were made on various types of dental handpieces, when operated free running and when used to cut tooth tissue. hearing acuity tests were also undertaken in 12 randomly selected dental surgeons who have been using these drills for a number of years. the results indicate ...

Evacuation drills are conducted periodically with the intent of practicing smooth evacuations from buildings, and for practicing rescue operations at emergency sites. An agentbased evacuation simulation with information diffusion provides a platform for simulating human evacuation behavior during emergencies that can be affected by various social and human factors. TENDENKO aims to conduct evac...

this research has been conducted due to changing of organizations' operating environment and the need of radical change in short time to facilitate the match between market opportunities and corporate capabilities. as hammer and champy found that 50-70% of attempts have been failed to deliver intended dramatic results, a preevaluation by less time and less costly from the current process d...
