veterinarians increasingly play a major contributory role in dairy practice and management. withincreasing importance of economical pressures, bioenvironmental limits and increasing demand for higherquality products, veterinarians are more involved in nutrition management and advice, both from aneconomical view of productivity and preventive aspects of veterinary medicine. the concept of food a...

PURPOSE Mouthguards are available to provide protection from stomatognathic injury during sports. The aim of this study was to examine the thickness of each part of mouthguard sheet depending on the thickness of mouthguard sheet material. METHODS Cross stripes (10 x 10 mm) were printed in mouthguard sheets. We measured the thickness of each cross stripe area using a measuring-device (R). Two ...

As a contribution to the mysteries of human symmetry perception, reaction time data were collected on the detection of symmetry or repetition violations, in the context of short term visual memory studies. The histograms for reaction time distributions are rather narrow in the case of symmetry judgments. Their analysis was performed in terms of a simple kinetic model of a mental process in two ...

High speed and absence of a precise control over pressure distribution confine sheet Electromagnetic Forming into a die to simple shapes having shallow depth. It is possible to reach a higher depth by using a convex punch instead of a concave die. In this study, sheet Electromagnetic Forming on a punch and sheet Electromagnetic Forming into a die are investigated. The electromagnetic part of th...

in this paper, the effect of cyclic loading on punching strength of flat slabs strengthened with carbon fiber reinforced polymer (cfrp) sheets is studied. experimental results of ten slab specimens under monotonic and cyclic loading are analyzed. eight specimens were strengthened with cfrp sheets on the tensile face of the slabs and the two other specimens were kept un-strengthened as control s...

The aim of this study was to investigate vacuum forming techniques for reduction of loss in mouthguard thickness effects of sheet grooving and thermal shrinkage of extruded sheets on molded mouthguard thickness. Mouthguards were fabricated with ethylene vinyl acetate (EVA) sheets (4.0 mm thick) using a vacuum forming machine. Sheet form was a convexing v-shaped groove toward the back, 10-40 mm ...

Large sheet thermoforming is widely used for the manufacture of parts such as twin sheet formed gas tanks, body panels and windshields. These complex technical parts require a precise temperature map to be realized prior to forming. In particular, the material used for forming gas tanks incorporates an EVOH barrier layer that is susceptible to tearing when exact processing conditions are not st...

The aim of this study was to investigate the thickness of mouthguard sheet after vacuum-pressure formation based on the mouthguard sheet material. Three mouthguard sheet materials (4.0 mm thick) were compared: ethylene-vinyl acetate co-polymer (EVA), olefin co-polymer (OL), and polyolefin-polystyrene co-polymer (OS). The working model was made by hard gypsum that was trimmed to the height of 20...
