Physics - Young's modulus - University of Birmingham
22 · The Young’s modulus ( E) is a property of the material that tells us how easily it can stretch and deform and is defined as the ratio of tensile stress ( σ) to tensile strain ( ε ). Where stress is the amount of force applied per unit area ( σ = F/A) and strain is extension per unit length ( ε = dl/l ). Since the force F = mg, we can ...

2017225 · Copper, a common chemical contaminant in aquatic environment, is known to be toxic to aquatic life at high concentrations. In the present study, we evaluated the apoptotic cell ratio and ROS production in hemocytes of the white shrimp Litopenaeus vannamei exposed to 1 or 5 mg L−1 Cu for 0, 3, 6, 12, 24, and 48 h. The expression
Copper metal does occur naturally, but by far the greatest source is in minerals such as chalcopyrite and bornite. Copper is obtained from these ores and minerals by smelting, leaching and electrolysis. The major copper-producing countries are Chile, Peru and China.
