An attempt is made Styling Strips to predict the pitting strength of cast iron and copper alloy materials from their compressive yield or compressive proof strength for a reliability of 99% at 107 load cycles.The compressive yield or compressive proof strength is related to the tensile strength of ductile cast iron and copper alloy materials by a p
The production of safe and healthy food products represents one of the main objectives of the food industry.The presence of microorganisms in meat and products containing meat can result in a range of human health problems, as well as economic losses to Posters producers of these products.However, contaminated meat products continue to initiate ser
A complex of soils characteristic of the Vladimir Opole Pet Supplies region was studied: agro-gray typical deep-arable soil, tongue-shaped agrozem and agro-gray gleyic soil.The high contrast of soil properties, which is due to the genesis of field landscapes, can be traced in the differences in the arable and subarable horizons of agro-gray soils a
