The incidence of invasive mold infections has increased during the 1990s among patients undergoing allogeneic hematopoietic stem cell transplantation (HCT) after myeloablative conditioning. In this study, we determined risk factors for invasive mold infection and mold infectionrelated death among 163 patients undergoing allogeneic HCT with nonmyeloablative conditioning. The cumulative incidence...

BACKGROUND Students spend a large portion of their day in classrooms which may be a source of mold exposure. We examined the diversity and concentrations of molds in inner-city schools and described differences between classrooms within the same school. METHODS Classroom airborne mold spores, collected over a 2 day period, were measured twice during the school year by direct microscopy. RES...

The image created by Guoyan Wang and Jimin He shows the “Jet Flow” phenomenon when UHMWPE melt is ejected from nozzle, on basis of which novel non-dense injection molding proposed to prepare microporous materials with much higher efficiency than traditional powder sintering. In this method, a large number Jet Flow particles produced under high-speed are loosely accumulated bonded in mold cavity...

Injection mold development lead time has been reduced presently by over 50% by employing rapid prototyping based tooling methods. Rapid tooling methods however, have certain limitations in terms of mold material, accuracy, surface finish, and mold life. The relevant process knowledge, especially for newer routes, is not very well established, resulting inconsistent or inappropriate rapid toolin...

UNLABELLED The public health risk and economic impact of dampness and mold exposures was assessed using current asthma as a health endpoint. Individual risk of current asthma from exposure to dampness and mold in homes from W.J. Fisk, Q. Lei-Gomez & M.J. Mendell [(2007) Indoor Air, [corrected] 17, 284-296], and [corrected] asthma risks calculated from additional studies that reported the preval...

The ASTM F-75 (Co-28%Cr-6%Mo) is widely used as a biocompatible alloy in medicinefor manufacturing implants. In this study, effect of mold preheating on the as-cast microstructure of thealloy was investigated using the solid investment casting process. Several mold preheating temperaturesof 550, 700, 850 and 1000 °C were selected at the same melt superheat. The samples were characterizedby opti...
