Introduction and objectives: Flexible ureteroscopy is a common procedure nowadays. Most of the training programs use virtual reality simulators. The aim of this study was to standardize the building of a three-dimensional silicone mold (cavity) of the collecting system, on the basis of polyester resin endocasts, which can be used in surgical training programs. Materials and Methods: A yellow po...

Since additive manufacturing technologies constantly advance, the use of this technology in mold making seems reasonable. Many manufacturers of additive manufacturing machines, however, do not offer any suggestions on how to parameterize the machine to achieve optimal results for mold making. The purpose of this research is to determine the interdependencies of different materials and parameter...

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 asthmatics and 35 control subject's houses were sprayed into Sabouraud dextrose agar. Allergy skin testing were performed in both groups. The tem...

Sanita-kun(R) Yeasts and Molds (SkYM), a novel dry sheet culture method for rapid enumeration of fungi, has been developed. This re-hydrated plate consists of a unique adhesive sheet, non-woven fabric coated with nutrients, antibiotic, water absorption polymer and uniquely synthesized 2-(2-methoxyphenyl)-3-(4-nitrophenyl)-5-phenyl-tetrazolium chloride for rapid enumeration of yeasts and molds. ...

Rapid prototyping is widely seen as an effective tool for compressing time to market for new products. The typical process followed by industrial and mechanical design groups is to model a new product in a CAD system, rapidly prototype the component parts, use the parts as patterns for RTV silicone molds, and then cast polyurethane prototype parts from the molds. These prototype components are ...

Pure carbon(C), nitrogen(N) and titanium(Ti) doped diamond-like carbon (DLC) coatings were deposited on silicon (Si) micro-molds by dc magnetron sputtering deposition to improve the tribological performance of the micro-molds. The coated and uncoated Si molds were used in injection molding for the fabrication of secondary metal-molds, which were used for the replication of micro-fluidic devices...

Bacteria and molds may spoil and/or contaminate apple juice either by direct microbial action or indirectly by the uptake of metabolites as off-flavours and toxins. Some of these microorganisms and/or metabolites may remain in the food even after extensive procedures. This study aim to identify the presence of molds (including heat resistant species) and Alicyclobacillus spp., during concentrat...

A mold is a fungus that grows in the form of multicellular filaments called hyphae. Molds are also called filamentous fungi that can be found both indoors and outdoors [1]. Molds breed best in warm, wet, and humid conditions, and they multiply and reproduce by making spores. No one knows how many species of fungi exist in nature, but estimates range from tens of thousands to perhaps a million o...

Casting metals and alloys makes most of the parts for vehicles. To shorten the time to market and get a satisfied quality new design approach have to be involved. New CAD based technologies are giving an opportunity to make molds faster and cheaper with a high quality than previously using classical methods. In this paper master mold design process including decision about materials is presente...
