Ukrainian companies mainly use birch in the manufacture of plywood, but species, such as black alder, are not yet widely used plywood due to their poorer properties. It is well known that thermal compression often improve properties solid wood. Good lay-up schemes veneer can maximize advantages and minimize disadvantages these wood generally utility value plywood. This research aimed develop pa...

The structural and aesthetic value of wood is typically sacrificed in an attempt to meet demand. This paper addresses the financial and quality aspects of silvicultural choices as it relates to wood veneers. Five trees each were harvested from an unevenaged stand and from the following evenaged stands: intensive plantation, conventional plantation, and natural regeneration. The 48-year old lobl...

[1] Dark mobile materials on Mars are widely considered to be volcanically derived windblown particulates. Such a conclusion is consistent with the large volcanic edifices on Mars and the assumption that a volatile-rich crust would not favor significant impact melt generation. Several post-Viking discoveries, however, provide new perspectives for reconsidering alternative origins not only for s...

The purpose of this study was to observe the tooth colors and retention of a cosmetic veneer Fiche Pearl On containing shellac and five experimental formulations containing benzoin gum and ethyl cellulose. Tooth color was measured with a spectrophotometer before and after application of the veneers to the buccal or labial surface of experimental teeth. Through both in vitro and in vivo studies,...

Objectives: The aim of the study was to evaluate marginal fit and fracture resistance after thermomechanical fatigue two types glass ceramic occlusal veneers constructed using techniques for wax pattern. Methods: Thirty-two non-carious maxillary molars were used in this study. Teeth prepared receive all veneers. Prepared teeth randomly divided into equal groups according fabrication material ve...
