In this research the relationship between graphitization ability and the carbon equivalent (CE %) of a cast iron have been investigated. The first series of moulds were cast at CE of 3.2% and pouring temperature of 1350°C. The other moulds were cast at different CE% with varying Si content. The graphitization ability( c ) was calculated using the thermodynamics aspects of graphitization and CE%...

Intra-radicular loss of tooth structure in endodontically treated teeth poses a challenge. Available methods for treatment are cast post-core, intra-radicular resin reinforcement using composite resin followed by placement of prefabricated metal/fibre post (glass or carbon).This study is an attempt to investigate the validity of treatment of such teeth using above methods and evaluate which pos...

Some scoliotic curves are developing into adulthood, mostly by lumbar discal decompensation and sometimes with evolving rotatory dislocation well described by Jean Dubousset. The Lyonaise conservative orthopaedic management is a protocol used for our patients for over 60 years. It consists of: 1° ) A lumbar plaster cast is taken, usually in standing position, over 3 weeks. This plaster cast is ...

The shear bonding strengths of a veneering resin to polished, sandblasted, and retention bead-cast commercially pure titanium (cpTi) plates with and without alkaline treatment were measured before and after thermal cycling. The bonding strengths to polished cpTi with and without alkaline treatment decreased remarkably with thermal cycling (p<0.01). The bonding strength to sandblasted cpTi with ...

A prospective randomised study was performed in order to compare plaster cast with Pliton-80 cast brace with a mobile plastic shoe insert in the treatment of ruptured fibular ankle ligaments. The two treatment groups consisted of 65 patients in each and all were participating in the follow-up sixth months after the accident. There were no statistically significant differences in the overall res...

Hypereutectic High Chromium Cast Iron (HHCCI) is a new type of corrosion-wear-resistant material developed from ordinary high chromium cast iron by increasing the and carbon content often used in abrasive environments where wear corrosion interact. The resistance HHCCI related to number, size, shape distribution carbides microstructure matrix. This paper reviews research progress improving vari...

Most of the previous treatment methods for auricular haematoma are inconvenient for both patients and doctors because they are time-consuming and complex and must be performed under sterile conditions. The purpose of this study was to evaluate the effectiveness of a simple compressive method using a dental (silicone) impression material and comparing it with other methods for treatment of auric...

BACKGROUND The conservative treatment of adolescent idiopathic scoliosis (AIS) has traditionally been divided into two phases-correction and stabilisation-and casts, even if less used today, can be considered the best standard in the correction phase. Till the present, however, no comparison between cast and brace efficacy has been proposed. METHODS This is a prospective cohort study with a r...

To the Editor, The Indian Medical Gazette StR,?I have read with considerable interest your leading article on epidemic dropsy in the October issue of the Gazette. I wish to draw your attention to one or two points in connection with your reference to our work on the subject. While offering criticism on the deductions made by us from our experiments you make no mention of the fact that albumin w...

association of genetic polymorphism in the calpastatin (cast) gene with average daily gain was examined in iranian purebred kurdi sheep. the genotypes for cast were determined by the pcr-sscp method. blood samples were collected from 84 purebred kurdi sheep belonging to the kurdi breeding station located in the khorasan province, north-east of iran. extraction of genomic dna was based on the gu...
