This paper discusses scientific research in the direction of energy saving and efficiency heat transfer processes. In this direction, particular, optimization design modernization exchange processes, as well development resource-saving technologies, it is necessary to reconsider lining thickness induction melting furnaces. The on lining, consists thermodynamic thermal processes taking place liq...

materials and methods: one hundred and thirty five mesial root canals of mandibular first and second molar teeth were selected. access cavities were prepared. after inserting a k-file size #10 into each canal, radiographs were taken. canal curvature was determined by measuring the schneider angle, canal access angle, as well as the canal radius, length, height and curvature starting distance on...

the aim of this study was to introduce modified continuous wave compaction (mcwc) technique and compare its obturation quality with that of lateral compaction (lc), warm vertical compaction (wvc) and continuous wave compaction techniques (cwc). the obturation time was also compared among the four techniques.sixty-four single-rooted teeth with 0-5° root canal curve and 64 artificially created ro...

Colonization of soft lining materials with microorganisms, espe­ cially Candida albicans, is a common clinical problem. Silicone­based soft li ning materials have been found to be particularly susceptible to Candi­ dal adhesion. This study investigated the Candida albicans adhesion to 6 silicone­based soft lining materials (Molloplast­B, Mollosil, Ufigel P, Ufigel C, Soft Liner and Luci­sof). F...

Traumatic spinal cord injury is one of the important causes of disability.in some of vertebral fractures,spinal canal is deformed and compromised.the relationship between the shape of the cervical canal and spinal cord hnjury has been proved but such a correlation for thoraculombar spine 50 patients with compromised canal(cases) and 50 oatients with intact canal were evaluated in the light of s...

The identification of ring canal proteins and insight into ring canal biogenesis have been aided by characterization of a class of mutants in which the flow of cytoLynn Cooley Department of Genetics Yale Medical School New Haven, Connecticut 06520-8005 plasm into the oocyte is impaired (Robinson and Cooley, 1996). The ultimate phenotype of these mutants is striking: egg chambers produce drastic...

We investigate the effect of steel plate lining at the rear face of the reinforced concrete panel on the ballistic properties using the semi-empirical model. We determine the structure of the two-layered shield that provides the maximum critical velocity for a given area density and depends on the mechanical properties of concrete and characteristics of the reinforcement. It is found that the o...

Introdouction: Variations in root canal morphology pose a challenge for successful endodontic treatment. The root canal anatomy of the maxillary first molar has been often described as three roots with four canals (two mesiobuccal, one distobuccal, and one palatal). The occurrence of two palatal canals in one palatal root is quite rare. This report represents the case of a maxillary first molar...
