Woven fabric reinforced composite materials are typically applied in plate or shell structures, such as ribs, stiffeners and skins. Products of this type can be manufactured with several processes. A few examples are compression moulding, diaphragm forming, matched metal die forming and Rubber Press Forming (RPF). Shape distortions can occur during manufacturing of composite products. During th...

Traditional environmental mould analysis is based on microscopic observations and counting of mould structures collected from the air on a sticky surface or culturing of moulds on growth media for identification and quantification. These approaches have significant limitations. A DNA-based method of mould analysis called mould specific quantitative PCR (MSQPCR) was created for more than 100 mou...

In this investigation, ^5 2-D Finite Volume Method (FVM) with unstructured triangular mesh is developed to simulate the mould filling process. The simulation of fluid flow and track of free surface is based on the Marker And Cell (MAC) technique. This technique has capability ofhandling the arbitrary curved solid boundaries in the casting processes. In order to verify the computational results ...

OBJECTIVES Moulds are frequently found in the indoor environment of residential houses. An association between domestic mould contamination and respiratory symptoms has been reported, but mould exposure as a risk factor for allergy to moulds is not well documented. The aim of the study was to evaluate the prevalence and associated factors of allergic hypersensitivity to moulds. MATERIALS AND ...

The making of ear mould for hearing aids is generally considered to be a safe process. However, there are a few reported cases of complications caused during mould making. We report the case of a man with 69 years age, where the process of making the mould for a hearing aid led to the perforation of the tympanic membrane and pouring of mould material into the middle ear, necessitating surgical ...

This article is focused on the calculation of heat radiation intensity and its optimization on an aluminum mould surface. The inside of the mould is sprinkled with a special powder and its outside is heated by infra heaters located above the mould surface, up to a temperature of 250°C. By this way artificial leathers in the car industry are produced (e. g. the artificial leather on a car dashbo...
