Objectives. The study's objective was to examine the relation between mold/dampness exposure and mold sensitization among residents of Greater New Orleans following Hurricane Katrina. Methods. Patients were recruited from the Allergy Clinic of a major medical facility. Any patient receiving a skin prick test for one of 24 molds between December 1, 2005 and December 31, 2008 was eligible for the...

Air pressure acting on building envelopes can wreak havoc with building performance if not properly understood and adequately designed for. Uncontrolled air pressure across the building envelope and within the building itself can cause infiltration and exfiltration that overpower HVAC systems. By disrupting the HVAC design, pressures can cause discomfort and create infection control and indoor ...

Multi-faceted experiments were conducted to measure the properties of several mold slags, needed for fundamental characterization of heat transfer and friction in the interfacial gap between the shell and mold during the continuous casting of steel. A novel apparatus was used to measure the friction coefficient between solidified mold flux and copper at elevated temperatures. The measured softe...

The objective of this study was to determine the physicochemical and sensory properties of Appenzeller cheese supplemented with different concentrations (0, 1, 2, 3, and 4%, w/w) of powdered microcapsules of tomato extracts (PMT) during ripening at 14℃ for 6 mon. The particle sizes of PMT ranged from 1 to 10 m diameter with an average particle size of approximately 2 m. Butyric acid (C4) concen...

Many phenomena in continuous casting including the formation of surface defects are greatly affected by heat transfer in the mold. The interfacial slag layers between the solidifying steel shell and the mold wall dominates the resistance to heat removal and thus controls mold heat transfer. Surface defects, such as longitudinal cracks and star cracks have been associated with variation of slag ...

mold powders are fluxing agents used as raw materials in the steel industry, which play very important role inprocessing stability and final surface quality of a product. surface quality depends particularly on the viscosity and the heat transfer of infiltrated mold flux between the mold wall and the solidified steel shell. heat flux across the interfacial gap depends on thermal properties of s...

One of the most important tasks remaining to be resolved in nanoimprint lithography is the elimination of the resist sticking to the mold during demolding. Previously, the main approach was to apply a thin layer of fluorinated alkyl silane mold-release agent on the surface on the mold; however, this involves complicated steps and high costs. The low surface free energy material polybenzoxazine ...

Mold Shape Deposition Manufacturing (Mold SDM) is a Solid Freeform Fabrication technique for producing complex shaped fugitive wax molds. A variety of castable polymer and ceramic materials have been used to make parts from these molds. This paper describes the Mold SDM method and an automated mold building machine based on a commercial CNC mill. Process steps, material selection and equipment ...
