the objective of this study was to evaluate different pistachio hullers and determine the proper harvest time of pistachio nuts for hulling. three pistachio hulling machines (helical drum, helical- blade drum, rubber drum) at three harvest times and 15 days interval were evaluated. the hulling efficiency, percentage of damaged nuts, faulty hulled nuts and unhulled nuts were measured at each tim...

Normal skin is composed of epidermis and dermis. Skin is susceptible to radiation damage because it is a continuously renewing organ containing rapidly proliferating mature cells. Radiation burn is a damage to the skin or other biological tissues caused by exposure to radiofrequency energy or ionizing radiation. Acute skin reaction is the most frequently occurring side effect of radiation thera...

The research described in this paper focuses on the application of modal strain techniques on a multi-girder bridge superstructure with the objectives of identifying the presence of damage and detecting false damage diagnosis for such structures. The case study is a one-third scale model of a slab-on-girder composite bridge superstructure, comprised of a steel-free concrete deck with FRP rebars...

Self-centering rocking walls are known as viable alternatives to typical shear walls, as they provide a number of solutions for eliminating seismic flaws of conventional designs. These rocking walls have a generally positive impact on the seismic behavior of structural systems, but their design makes them susceptible to concrete crushing around their base, which can lead to significantly advers...

One of the serious damages of tremendous earthquakes is the damage to bridges as the major components in an    arterial road network, as relief operation is interrupted following cutting roads. Regardless of the magnitude and severity of an earthquake, other factors are also important in the strength and seismic performance of concrete bridges. Freezing-thawing cycles are among the factors, whi...

In this paper, evaluation results are presented for multi-temporal interferometric coherence analysis using a Synthetic Aperture Radar (SAR) for damage assessment in an urban area. The latest space-borne SARs potentially have a high enough spatial resolution to assess individual buildings. However, interferometric coherence analysis has not been evaluated for its limitation in sensitivity and s...

Glucose-6-phosphate dehydrogenase (G6PD) deficient subjects are vulnerable to oxidative stress. Quercetin, a flavonoids, has been employed as a potent oxygen-free radical scavenger in order to assess the protective effects of quercetin against H2O2-induced oxidative damage in G6PD-deficient and normal human erythrocytes. Erythrocytes of G6PD-deficient (n = 10) and normal (n = 10) subjects were ...

The implications of speckle statistics on laser eye-safety considerations are evaluated. The concept of speckled speckle is introduced, and its statistics are shown to correspond to the K0 function. Speckled speckle is defined in terms of the retinal power density when the eye is viewing an optically rough surface that is illuminated by a laser beam diffused through a ground-glass screen-a situ...

Objective (s):Rheumatoid arthritis (RA) is a chronic systemic inflammatory disorder, primarily targeting the synovium and articular cartilage that leads to joint damage. Recent reports have suggested the role of adipocytokines in mediating joint damage; however it still is a matter of debate. The purpose of this study was to evaluate the association between serum values of adiopocytokines (lept...

introduction: cypermethrin causes its neurotoxic effect through voltage-dependent sodium channels and integral protein atpases in the neuronal membrane. brain and nerve damage are often associated with low residual level of pesticides. in vitro and in vivo studies have also shown that pesticides cause free radical-mediated tissue damage in brain. propolis has antioxidant properties. the main ch...
