A novel micromolding approach was developed to process liquid biopolymers with high aqueous solvent contents (>90% water). Specifically silk fibroin was cast into a well-defined scaffold-like structures for potential tissue engineering applications. A method was developed to pattern the hydrophilicity and hydrophobicity of the polydimethylsiloxane (PDMS) mold surfaces. The water based biopolyme...

CASE A 53-year-old male sustained a high-pressure water injection injury to his foot while working in a river. He was taken to the operating room for emergent irrigation and debridement of copious riverbed sediment. Cultures taken from the operating room were positive for multiple anaerobes, fungus and mold and he was treated with appropriate antibiotics. To date, his only residual deficit is a...

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...
