Chemical composition of corn kernels after a hydrothermal .

The influence of a hydrothermal "cooking" procedure on the starch, protein and oil contents was investigated on two corn hybrids of the same vegetation group (Bc 354 and Bc 394).

Stress Analysis of Thin-Walled Pressure Vessels

Pressure vessels are subjected to tensile forces within the walls of the container. The normal stress in the walls of the container is proportional to the pressure and radius of the vessel and inversely proportional to the thick-ness of the walls [3][2]. As a general rule, pressure vessels are considered to be thin -walled when the ratio of
