Aim of the present investigation was to assess the in vitro efficacy of different plant extracts againsts fungi isolated from bovine mastitis cases. Twenty-six species of yeast, yeast like and moulds were isolated from 200 mastitic milk samples. The isolates were identified based on the staining, cultural and biochemical characteristics. Aqueous extracts of cinnamon leaf, lemon grass, clove, an...
According to FAO – ISPM No 15, in international trade wood packaging material on the basis of sawn timber requires to be heat-treated to avoid spreading of harmful organisms. “Heat-treatment” means a minimum core temperature of the wood of 56° C for a minimum of 30 minutes. ISPM No 15 does not defi ne moisture content and therefore does not include rules for the drying process. Practitioners re...
The influence of mould level instability during continuous casting on the unevenness initial solidified shell in hypo-peritectic steels has been investigated. Water model experiments and in-plant revealed that instability, which increases with increasing speed, is related to longitudinal cracking resulting from solidification shell. A numerical considers effect was developed used simulate forma...
During the demoulding stage of the hot embossing process, the force required to separate a polymer part from the mould should be minimized to avoid the generation of structural defects for the produced micro structures. However, the demoulding force is dependent on a number of process factors, which include the material properties, the demoulding temperature, the polymer pressure history and th...
Slime mould Physarum polycephalum is large single cell with intriguingly smart behaviour. The slime mould shows outstanding abilities to adapt its protoplasmic network to varying environmental conditions. The slime mould can solve tasks of computational geometry, image processing, logics and arithmetics when data are represented by configurations of attractants and repellents. We attempt to map...
Slime mould Physarum polycephalum is a large single cell visible by unaided eye. We design a slime mould implementation of a tactile hair, where the slime mould responds to repeated deflection of hair by an immediate high-amplitude spike and a prolonged increase in amplitude and width of its oscillation impulses. We demonstrate that signal-to-noise ratio of the Physarum tactile hair sensor aver...
BACKGROUND There are few longitudinal studies that have examined the association of lung function decline with indoor mould and dampness. Lung function decline in relation to dampness and mould in the home has studied in adults over a 9 year period. METHODS Spirometry was performed twice in participants in the European Respiratory Health Survey (ECRHS I and II) who were initially examined age...
Abridged version of the AWMF guideline for the medical clinical diagnostics of indoor mould exposure
This article is an abridged version of the AWMF mould guideline “Medical clinical diagnostics of indoor mould exposure” presented in April 2016 by the German Society of Hygiene, Environmental Medicine and Preventive Medicine (Gesellschaft für Hygiene, Umweltmedizin und Präventivmedizin, GHUP), in collaboration with the above-mentioned scientific medical societies, German and Austrian societies,...
This article is focused on the infrared heating of shell metal moulds and optimization of temperature field on the surface of the mould. The upper part of the mould is heated by infrared heaters, and after the required temperature is attained the inner part of the mould is sprinkled with special PVC powder. The moulds are made of aluminium or nickel alloys. The described mathematical model allo...
