Listeria monocytogenes is an important re-emerging pathogen which is commonly found in the environment. Many outbreaks have been associated with the contamination of food produce, often linked to cross-contamination from surfaces or equipment to prepared foodstuffs. In the present study a number of copper-base metal alloys have been used to assess the survival times of L. monocytogenes on diffe...
The most important aspect of any engineering material is its structure. The methods used to accurately determine the material microstructures is a very time-consuming process, causes operator fatigue, and it is prone to human errors and inconsistency. There are two computational approaches, a feature features and a neural network algorithm, are used separately for classifying and detection of s...
Water is most essential for existence of life on earth. Water is the basic necessity of all living creatures and its important use are for drinking purpose. Water intended for human consumption must be safe and free from microbes. Therefore this investigation was taken with the objective to study the effect of storage of lake water in different vessels like plastic, clay, copper and stainless s...
Copper alloys surfaces have been proposed as a promising solution to avoid microbial contamination of but their antibiofilm effect is still unclear. All copper tested demonstrated efficient activity against Methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa, with differences between alloys. The artificial aging led variable effects on the bacterial adhesion, depending...
the objective of this study was to develop a numerical model for the prediction of temperature distribution, effective plastic strain distribution, and especially material flow in friction stir welding of copper plates. the deform-3d software was used by incorporating a lagrangian incremental formulation. threedimensional results of the material flow pattern which were extracted using the point...
the openings of copper converter in sarcheshmeh copper complex in iranis made of a heat resisting austenitic steel (fe-25cr-12ni) and many failures have been reported. understanding the failure mechanism of the alloy helps to develop better alloys for similar complex environments. samples of as-cast alloy and those taken from failed ones were examined. optical microscopy (om), x-ray diffraction...
