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 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...

K. Janiszewski, Silesian University of Technology, Department of Metallurgy, Katowice, Poland. Hitherto existing investigations concerning the ceramic fi lter use in the steel making processes (both of laboratory and industrial scale) have given good results. The obtained results of fi ltration (in the laboratory) have proved that this method may be used as an eff ective and cheap way of steel ...

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...

Protective slag is coated on the surface of molten steel during continuous casting, flow and heat transfer state protective a decisive factor affecting inflow consumption liquid also an important prerequisite for stabilizing improving quality casting billets. Based Navier Stokes fluid momentum conservation equation energy equation, two-dimensional longitudinal numerical model describing flow/he...

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...

Abrasive wear is one of the prime and mostly costly causes of secondary failure in the design and operation of mechanical machines and equipment. Wear limits must be known and measured to assure quality and durability of products by an experimental process to determine an optimum material composition. The development of wear monitoring systems for industrial processes is well recognised in the ...

We present two implementations of the Cube-4 volume rendering architecture on the Teramac cus­ tom computing machine. Cube-4 uses a slice­ parallel ray-casting alg01'ithm that allows for a paral­ lel and pipelined implementation of ray-casting with tri-linear interpolation and su'rface normal estima­ tion from interpolated samples. Shading, classifica­ tion and compositing are part of rendering...

We present two implementations of the Cube-4 volume rendering architecture, developed at SUNY Stony Brook, on the Teramac custom computing machine. Cube-4 uses a slice-parallel ray-casting algorithm that allows for a parallel and pipelined implementation of ray-casting. Tri-linear interpolation, surface normal estimation from interpolated samples, shading, classi cation, and compositing are par...

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...
