Study Design: A prospective, observational case series of eighteen children with early onset scoliosis undergo spine manipulation and casting. Objective: Determine if respiratory system compliance decreases during casting warrants tracheal intubation in all Derotational casting procedures. Background: Children with early onset scoliosis with a Cobb angle greater than 25 degrees will have signif...

The effect of 12 different experimental compositions of phosphate-bonded SiO2 investments was examined on cast pure titanium. The mold temperature was 600 degrees C and the casting was conducted with an argon-arc melting and pressure casting machine. Castability was evaluated by the volume of casting porosity, which was calculated from the volume of wax pattern (15 mm x 15 mm x 1.5 mm), the wei...

The lost foam casting process offers several advantages over traditional green sand casting, most notably the ability to reuse casting sand, thus eliminating the need for costly disposal of contaminated casting sand. The process does, however, produce significant quantities of airborne emissions that can be a danger to both the environment and to the health of workers. This research examines th...

IntroductIon Solidification structure and macrosegregation have great influence on the quality of high carbon steels. Center segregation in high carbon steel results in a high concentrations of chemical components especially carbon element and has a great influence on the quality of wire rod [1-3]. Wire rod with center cementite network resulting from severe segregation not only shows low ducti...

Now a day there is an emerging interest in replacing non-renewable additives with biodegradable compounds. Cellulose plays very important role in this modification. Their low cost and low density associated with high specific mechanical properties represent a good renewable and biodegradable alternative to the most commonly used synthetic reinforcement. The cellulose was modified by using 2-(Tr...

The aim of this work is to improve the quality of castings by minimizing defects and scrap through the analysis of the data generated by High Pressure Die Casting (HPDC) Machines using computational intelligence techniques. Casting is a complex process· that is affected by the interdependence of die casting process parameters on each other such that changes in one parameter results in changes i...

Animal momentum and heat transfer analysis has historically used direct animal measurements or approximations to calculate drag and heat transfer coefficients. Research can now use modern 3D rendering and computational fluid dynamics software to simulate animal-fluid interactions. Key questions are the level of agreement between simulations and experiments and how superior they are to classical...

Since zinc die casting’s conception over 100 years ago, many new and improved developments have taken place to progress the industry and offer component designers a costeffective alternative to higher priced alloys and processes. The zinc industry has continued to develop new alloys in response to some of the challenges that face it. One such development is EZACTM, Eastern Alloys’ high strength...

Organic vegetable production has specific research and innovation requirements which are not shared by other parts of the food and farming sector. A pot experiment was conducted to investigate the interactive effects of few permitted organic inputs such as arbuscular mycorrhizal fungi, biochar, and different ratios of peat:worm casting on tomato (Solanum lycopersicum L.) growth, mycorrhizal dep...
