German water guidelines do not recommend routine assessment of cold water for Legionella in healthcare facilities, except if the water temperature at distal sites exceeds 25°C. This study evaluates Legionella contamination in cold and warm water supplies of healthcare facilities in Hesse, Germany, and analyses the relationship between cold water temperature and Legionella contamination. Samples...

Owing to the progressive use of cold-formed high strength steel (HSS) for transportation applications, a characterisation fatigue behaviour HSS has become focal point material scientists and design engineers. To mimic components, specimen was adopted from previous research that features multiple bent sections. The geometry obtained by consecutive bending operations at room temperature. When sub...

In the yeast, meiotic recombination is initiated by double-strand DNA breaks (DSBs) which occur at relatively high frequencies in some genomic regions (hotspots) and relatively low frequencies in others (coldspots). Although observations concerning individual hot/cold spots have given clues as to the mechanism of recombination initiation, the prediction of hot/cold spots from DNA sequence infor...

The prediction of the glass-forming ability (GFA) metallic glasses (MGs) can accelerate efficiency their development. In this paper, a dataset was constructed using experimental data collected from literature and books, machine learning-based predictive model established to predict GFA. Firstly, classification based on size critical diameter (Dmax) determine whether an alloy system could form g...

Cold forging is often applied in the fastener industry. Wires in coil form are used as semi-finished products for the production of billets. This process usually requires preliminarily drawing wire coil in order to reduce the diameter of products. The wire usually has to be annealed to improve its cold formability. The quality of spheroidizing annealed wire affects the forming quality of screws...
