Abstract For a long time, research on the pre-Han (before 202 BCE) Chinese use of lost-wax process was targeted at demonstrating that it no all. That position severely shaken when zun-pan set Zeng Hou Yi (“Marquis Zeng,” d. 433 unearthed Hubei Suizhou in 1978, along with subsequently excavated finds or rediscovered artifacts carrying similarly interpenetrating openwork. Since early 2000s, howev...

The article discusses the technology of casting according to smelted models, in particular, processes manufacturing wax models. We considered methods elements model blocks with use molds and help additive technologies. In this paper we showed features application technologies lost-wax casting. A simulation has been developed evaluate effectiveness using printing produce Based on results modelin...

AIM A common problem related to cemented single crowns is the internal misfit, which may cause inadequate retention, especially when seated on the implant abutment. The aim of this study was to compare the internal fit of Co-Cr crowns using a traditional lost-wax casting technique from laser-sintered Co-Cr alloy crowns. MATERIALS AND METHODS Twelve metallic crowns per each technique were fabr...

The layer of wax secreted on to the surface of the cuticle by arthropods plays an important part in protecting these animals against physico-chemical hazards of their environment, and so contributes significantly to the difficulty and expense of controlling economically undesirable species. In spite of this importance, however, very little is known about the biosynthesis of cuticle wax or the q...

BACKGROUND AND AIMS The slippery waxy zone in the upper part of pitchers has long been considered the key trapping structure of the Nepenthes carnivorous plants; however, the presence of wax is reported to be variable within and between species of this species-rich genus. This study raises the question of the adaptive significance of the waxy zone and investigates the basis for an ontogenetic c...

This report describes the case of a 42 years old male patient whose one right hand finger was partially lost as a result of occupational trauma. A modified impression technique was used for impression making and wax pattern was fabricated using the normal hand of the same patient. A special type of wax was formulated to make a pattern which was easily molded and carved. Two indexed casts were u...

An experimental polyethylene–candelilla-wax coating formulation was evaluated in comparison to a high-gloss, shellac and wood resin citrus coating for storage of ‘Valencia’ oranges at 15–25°C. Oranges with the wax coating had relatively high flavor scores (8.9–10.4) even after 9–16 days storage at 15–25°C. By contrast, the high-gloss coating, shown to be typical of such citrus coatings, resulte...
