introduction: the role of ovarian hormones and nitric oxide (no) on oxidative damage in brain tissues as well as learning and memory has been widely investigated.the present study was carried out to evaluate the effect of the precursor of no, l-arginine on learning and brain damage due to oxidative stress in ovariectomized (ovx) rats.methods: thirty -two rats were divided into four groups: 1) s...

an analytical nonlinear stress-strain model and a microscopic damage index for confined and unconfined concretes together with a macroscopic damage index for reinforced concrete (rc) structures under cyclic loading are proposed. in order to eliminate the problem of scale effect, an adjustable finite element computer program was generated to simulate rc structures subjected to cyclic loading. by...

The heavy metal cadmium (Cd(2+)) applied on tobacco roots in the form of cadmium chloride, induced significantly higher levels of DNA damage as measured by the cellular Comet assay than did treatment of isolated root nuclei, analyzed by use of the acellular Comet assay. DNA damage induced by Cd(2+) in roots of a transgenic catalase-deficient tobacco line (CAT1AS) was higher than in wild-type to...

in this paper, the capabilities of displacement curvature derived from static response data for finding the location and severity of damage in euler-bernoulli beams are assessed. static response of a beam is obtained using the finite element modeling. in order to reduce the number of measured nodal displacements, the beam deflection is fitted through a polynomial function using a limited number...
