this paper deals with an inspection of defects including corrosion and leakage by acoustic emission (ae) in an oil tank floor. in contrast to intrusive methods such as magnetic flux leakage, eddy current or ultrasonic, there is no need to emptying and entering the tank in ae method in order to inspection. in this research ae investigation and ae source location is presented in detail. the resul...

OBJECTIVE Effective treatments for social anxiety disorder (SAD) exist, but additional treatment options are needed for nonresponders as well as those who are either unable or unwilling to engage in traditional treatments. Mindfulness-based stress reduction (MBSR) is one nontraditional treatment that has demonstrated efficacy in treating other mood and anxiety disorders, and preliminary data su...

biological research of all kinds on mosquitoes must be built upon a foundation of correct identification and sound classification. except for the anopheline vectors of malaria, relatively little is known about other mosquitoes in iran and other countries in southwest asia. in view of this a comprehensive study on the mosquito fauna of iran has started since 1981. in this report the list of the ...

The HF/3s2pld and MP213s2pld structures, energies and vibrational frequencies were calculated for ten N8 isomers, corresponding to ten analogous CH structures. Comparative calculations using density functional theory (DFT), with a cc-pVTZ basis set, were also performed. All ten structures were found to be local minima on the energy hypersurface at the Hartree-Fock (HF) level, whereas at the sec...

The effects of different muscle loading exercise (MLEX) modes and volume on musculoskeletal health is not well-studied in older populations. Aim: Therefore, this study aimed to compare the community-based MLEX modalities elderly people. Methods: Elderly men (n = 86) women 170), age 50–82 years old, were assigned sedentary (SE, n 60), strengthening (MSE, 71), aerobic (AE, 62) Tai Chi (TCE, 63) g...

The increased industrialization and overuse of natural resources for energy, such as fossil fuels, have led to the energy crises environmental issues that plague world in twenty-first century. production biodiesel from algae has recently gained attention a potentially useful alternative fuel is both environmentally friendly easy obtain. In this work, effects various pH levels on biomass oil Chl...
