STATEMENT OF PROBLEM In complete mouth reconstructive dentistry, the occlusal vertical dimension may be increased to provide adequate restorative space or to improve esthetics. The effect of increasing the occlusal vertical dimension on the smile is not well understood. PURPOSE The purpose of this study was to evaluate the effect of increasing the occlusal vertical dimension on the dimensions...

The goal of the study was to analyse statistically the survey of measurable parameters distinguishing human facial skeleton as well to construct mathematical model describing foetal facial skeleton selected features. The material consisted of 112 foetuses (44 females – 39.29% and 76 males – 60.71%) in the CRL: 83-245 mm, aged 4-7 months of foetal life. The whole of the examined material origina...

Gender determination of Muscovy duck as early possible is essential for the efficiency and effectiveness production. This study aimed to determine morphometric differences in prepubertal male female (Cairina moschata) predictors gender. used a split-plot design, with observed variables cranium length, width height, mandibular rostrum length width. total 80 samples heads consisting 40 heads, ten...

As the urban underground space environment gets more complex, cases of shield machines encountering and cutting through piles are becoming common. The interaction between cutter head pile foundation directly affects tunneling performance machine safety existing structure. To study machine, a calculation model force is established. A field test two was conducted rationality verified by comparing...

Abstract By studying ecomorophology in the context of phylogeny, researchers can parse out similarity due to common ancestry versus that convergence. This is especially true among relatively closely related species where both phylogenetic and environmental constraints may be operating simultaneously. We explored these issues three karst-associated from two lineages Cyrtodactylus —the sworderi g...

during a survey conducted in apple orchards of boyer-ahmad and dena regions, in summer of 2013 and 2014, a species of tylenchus was recovered which was identified as t. naranensismaqbool, zarina & ghazala, 1987 based on morphological and morphometric studies. this is a new report for iran and describe here. female: ventrally curved to c-form, head continuous with body contour, cephalic framewor...

Head direction cells are described in the presubiculum of the macaque, used as a model of what is likely to be present in humans. The firing rate of these cells is a function of the head direction of the monkey, with a response that is typically 10-100 times larger to the optimal as compared to the opposite head direction. The mean half-amplitude width of the tuning of the cells was 76 degrees ...
