Indoor mold growth has recently become a concern in the legal world in regards to insurance litigation. Hazardous mold exposure to humans has been linked to many acute and chronic adverse health effects including death. As it grows, mold produces several types of primary and secondary metabolites, including microbial volatile organic compounds (MVOCs). Microbial volatile organic compound emissi...

New products must be more quickly and cheaply developed, manufactured and introduced to the market due to the pressure of global competition. This work demonstrates a technique for producing accurate wax patterns made from a high precision silicone rubber mold. Silicone rubber mold is cut into five components, which is the minimum number of components for assembling the silicone rubber mold. Th...

1. A powerful kinase which changes trypsinogen to trypsin was found to be present in the synthetic liquid culture medium of a mold of the genus Penicillium. 2. The concentration of kinase in the medium is increased gradually during the growth of the mold organism and continues to increase for some time even after the mold has ceased growing. 3. Mold kinase transforms trypsinogen to trypsin only...

Low-pressure powder injection molding (LPIM) is a cost-effective technology for producing intricate small metal parts at high, medium, and low production volumes in applications which, to date, have involved ceramics or spherical powders. Since the use of irregular powders represents promising way reduce overall costs, this study aims investigate potential manufacturing molded from commercial i...

Background: Butter is one of the oldest dairy products known in the world and plays an important role in human nutrition. The aim of this study was evaluating of the microbial quality of traditional   and industrial butter marketed in Zanjan. Methods: In this descriptive cross-sectional study, a total of 29 samples of butter were investigated in 2 groups which 24 samples were of trad...

in this paper, the accumulative channel-die compression bounding (accb) method is investigated as a new method of severe plastic deformation to produce nano-crystalline bulk metals on the basis of pressing in a channel mold. aluminum as one of the most usable metal in industry is processed using this method. analyzing the processed samples show that after four passes of accb method, the ultimat...

Continuous casting plants are highly complex plants whose performance requires reliable mold level control system. Several effects greatly influence the surface quality of the final product and if these are not suppressed sufficiently by the mold level control system, than the production speed, hence the productivity has to be lowered. This paper analyses the most important disturbance and thei...

We present a simple and effective mold cleaning method for nanoimprint lithography. Polydimethylsiloxane (PDMS) prepolymer is spin-coated onto a contaminated imprint mold, thermally cured in ambient environment, and then peeled off afterwards. Contaminants of 100s m to sub-50 nm sizes are effectively cleaned within one cycle. During the cleaning process, a very thin PDMS film (1~2 nm) is unifo...

A high-dose-rate (HDR) 192-Ir brachytherapy using a customized intraoral mold is effective for superficial oral cavity cancer, and the surrounding normal tissue is kept away from the radioactive source with gauze pads and/or mouth piece for reducing the dose on the normal tissues. In the Tokushima university hospital, the mold has a lead shield which utilizes the space prepared with sufficient ...
