Foamed concrete is a special type of and it can be used widely in construction reinforced structures. this study very helpful for understanding about foamed mechanical properties concrete. Lot researches are going on material finally we got It has lot advantages compared to conventional Fluidity Flowability good the foam low cost high Manufacturing Production poly urethane simple easy. because ...

The interactions between natural and synthetic materials and blood components are analyzed with emphasis on the interdependence between biomaterials research and development and ultimate applications. Two new synthetic polymers, perfluorobutyryl ethylcellulose and polyalkylsulfone, that combine desirable blood compatibility and gas-to-blood transfer rates are discussed in terms of their potenti...

PURPOSE In this pilot study, we tested a newly developed electrospun multilayered, self-sealing graft, AVflo™, specifically designed for early hemodialysis access. 
 METHODS Ten eligible consenting patients had a polycarbonate-urethane graft (AVflo™) implanted and were followed up prospectively for at least six months. Performance measures included graft patency, complications and time to fir...

The present report describes the fabrication technique and dosimetry aspects of a desktop numerically controlled milling machine (NC-Mill) based a compensator system that uses lead clay (Shield cray, Reactor Experiments, Inc., U.S.A.). Effective path lengths of patients were determined for CT image sets using the ray-tracing technique and converted to compensator thickness with the equivalent T...
