Aim: Excessive material thinning has been observed in the production of custom-made mouthguards in a number of studies, due to production anomalies that may lead to such thinning. This study investigated the effect of thinning material patterns of custom made mouthguards when the anterior angulation of dental model was increased during the thermoforming process. Materials & Methods: A total of ...

We investigated whether vertical-shear disparity was extracted from the whole visual field or from a more local area and how global estimates of vertical disparity are derived. We also investigated the role of cyclovergence in processing shear disparity. Random-dot stereoscopic displays in various configurations were presented with horizontal-shear disparity, vertical-shear disparity or same-si...

This study provides a new systematic approach to predicting the effects of spray inclination on critical heat flux (CHF). Experiments were performed with three pressure spray nozzles over a broad range of inclination angles at five flow rates and subcoolings of 15°C and 25°C. These experiments also included high-speed video analysis of spray formation, impact, and recoil for a 1.0 1.0 cm2 test ...

[Purpose] The purpose of the present study was to investigate the relationship between the duration of the car transfer (CT) movement and trunk inclination and hip angles during this movement in individuals with tetraplegia. [Subjects and Methods] Eleven adult males with C6 tetraplegia participated in this study. The CT movement was recorded from the passenger side of the car using a digital vi...

conclusions this study did not show that distal radius anatomical indices including the radial height, radial inclination, ulnar variance and volar tilt influence perilunate fracture dislocation as risk factors. background distal radius radiographic indices may play a role as risk factors in pathogenesis of kienbock’s disease, scaphoid fracture and non:union:. perilunate fracture dislocations a...

For the characterization of mechanical deformation materials at microscopic length scales, image processing a high-quality surface pattern was used. We imprinted speckle patterns onto thin polymer film attached to flat and curved metal substrates using flexible molds soft-thermal nanoimprint lithography. High optical contrast achieved by mixing black dye into generating high absorption in eleva...

The dimensional factors of the cervical undercut of the human teeth were measured. The facial and lingual undercuts showed considerable deviations in depth, width, and inclination to the crown axis and the food stream. The proximal undercuts showed a uniform depth of 1 +/- 0.3 mm with some deviations in width and inclination.

This paper presents results of a numerical study of mixed convection and entropy generation of Cu–water nanofluid in a square ventilating cavity at different inclination angles. Except a piece of bottom wall with a uniform heat flux, all of the cavity walls are insulated. The inlet port is placed at the bottom of the left wall and the outlet port is positioned at the top of the right wall....

in this study the reproductive organs of adult and apparently healthy female azarbaijan buffaloes werecollected after slaughter from abattoir. through observation of the ovaries, the luteal and follicular phases ofeach buffalo were specified. a total number of 36 oviducts at follicular phase and 36 oviducts at luteal phasewere collected and 3 tissue samples were taken from 3 regions of infundib...
