Several strategies to increase the FCC austenite stability compared BCC and HCP martensites have been tested are discussed. The relative of different phases was analyzed by studying effects of: a) grain size, b) antiferromagnetic ordering austenite, c) thermal cycling through FCC-HCP transition, d) plastic deformation e) combined effects. As a first step, effect decreasing size in Fe–Mn alloys ...

Interaction of Alfven waves with plasma inhomogeneity generates phase mixing which can cause the dissipation of Alfven waves. We investigated the dissipation of standing Alfven waves due to phase mixing at the presence of steady flow and sheared magnetic field in solar spicules. Moreover, the transition region between chromosphere and corona was considered. Our numerical simulation showed that ...

A solid-phase extraction (SPE) method for sample clean-up and preconcentration followed by reversed-phase high-performance liquid chromatography (RP-HPLC) with uv detection is reported for determination of polycyclic aromatic hydrocarbons (PAHs) in the caspian seawater. A good resolution was obtained using acetonitrile:water (40:60) as mobile-phase for separation of these compounds. The eff...

The research was an applied study in terms of objective and an exploratory mixed method in terms of data collection methodology. The statistical population was composed of agricultural businesses and their personnel in the incubator of Razi...

introduction: hyperalgesia is considered as one of the marked signs of subchronic diabetes mellitus in patients that could affect their lifestyle. this study was designed to investigate the anti-nociceptive effect of chronic administration of quercetin in streptozotocin (stz)-diabetic rats using formalin and hot tail immersion tests. methods: rats were divided into control, control or diabetic ...
