background: the effect of mold fungi to allergic sensitization is not well-known. we aimed to evaluate the role of molds in the relation between indoor environment and atopy in asthmatics. materials and methods:the air samples obtained from 66 stable asthmaticsand 35 control subject’shouses were sprayed into sabouraud dextrose agar. allergy skin testing were performed both groups. the tempera...

Results from mathematical models and plant experiments are combined to quantify the effect of transverse depressions and oscillation marks on heat transfer in the continuous casting mold. A heat transfer model has been developed to calculate transient heat conduction within the solidifying steel, coupled with the steady-state heat conduction with the continuous casting mold wall. The model feat...

We describe a novel UV-curable mold that is stiff enough for replicating dense sub-100-nm features even with a high aspect ratio. It also allows for flexibility when the mold is prepared on a flexible support such that large area replication can be accomplished. The composite material of the mold is inert to chemicals and solvents. The surface energy is made low with a small amount of releasing...

Molten metal meniscus profile and mold flux channel width were measured under high frequency magnetic field by model experiments, then the dynamic pressure in mold flux channel were calculated during one mold oscillation period. It is found that the high frequency magnetic field can decrease the dynamic pressure greatly, which may be one mechanism of improving the billets surface quality by the...

In-mold Assembly process at the mesoscale presents several manufacturing challenges. Results reported in this paper demonstrate the technical feasibility of creating rigid body mesoscale revolute joints using In-Mold Assembly process. The following new results are reported in this paper. First, we describe a mold design with varying cavity shape to perform In-Mold Assembly. This mold design use...

In this paper, we fabricated a fluorinated organic-inorganic hybrid mold using a nonhydrolytic sol-gel process which can produce a crack-free mold without leaving any trace of solvent. No special chemical treatment of a release layer is needed because the fluorinated hybrid mold has fluorine molecules in the backbone. The other advantages of the hybrid mold are thermal stability over 300 degree...

background the importance of preserving and maintaining printed materials is crucial for the libraries. fungi play the main role in destroying wood and paper. objectives this research aimed to study and identify threatening fungal agents of library resources in isfahan university of medical sciences. materials and methods this is a descriptive analytical study. 126 samples were collected and ex...

The environmental relative moldiness index (ERMI) metric was previously developed to quantify mold contamination in U.S. homes. This study determined the applicability of the ERMI for quantifying mold and moisture damage in Finnish residences. Homes of the LUKAS2 birth cohort in Finland were visually inspected for moisture damage and mold, and vacuumed floor dust samples were collected. An ERMI...

An important step in the mold design process that ensures disassembly of mold pieces consists of identifying various regions on the part that will be formed by different mold pieces. This paper presents an efficient and robust algorithm to find and highlight the mold-piece regions on a part. The algorithm can be executed on current-generation computer graphics hardware. The complexity of the al...

Mold contamination is a growing concern for homeowners in terms of both physical health and insurance. Health experts, although they concede that exposure to mold can cause respiratory illnesses, are calling for further research into other mold-related health effects and for development of standards for mold sampling and data analysis. The insurance industry is grappling with how---and whether-...
