Abstract Polyolefin fiber is a new type of that was used in concrete to improve some the poor properties including; tensile strength, ductility, and fracture energy. In this research, contribution improving hardened examined by adding polyolefin fibers mix with different content. The polypropylene were added as ratio 0.5, 0.75, 1.0, 1.5, 2% volume. Destructive non-destructive tests carried out:...

Great efforts had been made to use indirect non-destructive tests in the geotechnical evaluation of rocks, especially sandstones, employing different empirical equations. However, most these equations have derived from hard and compacted sandstones data; therefore, focus this research is on weak weakly aiming firstly obtain for estimating their characteristics, secondly demonstrate visualize co...

BACKGROUND Racetrack surface is a risk factor for racehorse injuries and fatalities. Current research indicates that race surface mechanical properties may be influenced by material composition, moisture content, temperature, and maintenance. Race surface mechanical testing in a controlled laboratory setting would allow for objective evaluation of dynamic properties of surface and factors that ...

BACKGROUND To compare the intraocular pressure readings obtained with the iCare rebound tonometer and the 7CR non-contact tonometer with those measured by Goldmann applanation tonometry in treated glaucoma patients. DESIGN A prospective, cross-sectional study was conducted in a private tertiary glaucoma clinic. PARTICIPANTS OR SAMPLES One hundred nine (54 males : 55 females) patients includ...

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...
