The influence of crack root radius and plastic material properties on the tip fields was evaluated by strain gradient plasticity theory, classical theory. A conventional mechanism-based (CMSG) theory used in study. stress single edge tension specimen are investigated numerically for a wide range variations. Five values curvature ρ = 0 (mathematical notch); 25 nm, 30 60 nm 100 were investigated....

Multispectral remote sensing has potential to provide quick and inexpensive information on sugarcane aphid, Melanaphis sacchari (Zehntner), pest status in sorghum fields. We describe a study conducted to determine if injury caused by sugarcane aphid to sorghum plants in fields of grain sorghum could be detected using multispectral remote sensing from a fixed wing aircraft. A study was conducted...

Global seasonal cycles of the wind and wind stress fields estimated from the 8-yr record (September 1999–August 2007) of wind measurements by the NASA Quick Scatterometer (QuikSCAT) are presented. While this atlas, referred to here as the Scatterometer Climatology of Ocean Winds (SCOW), consists of 12 variables, the focus here is on the wind stress and wind stress derivative (curl and divergenc...
