the volatile constituents of aerial parts of euphorbia aellenii rech.f. and e. microsciadea boiss. were analyzed by gas chromatography (gc) and gc-mass spectrometry (ms) methods. the main volatile constituents of e. aellenii were phytol isomer (47.3%), camphene (31.9%) and caryophyllene oxide (20.6%), while the major volatile components of e. microsciadea were trans-anethole (74.5%), limonene (...

Menthae Haplocalycis herba, one kind of Chinese edible herbs, has been widely utilized for the clinical use in China for thousands of years. Over the last decades, studies on chemical constituents of Menthae Haplocalycis herba have been widely performed. However, less attention has been paid to non-volatile components which are also responsible for its medical efficacy than the volatile constit...

Phase Change Memory is one of the best candidates for next generation non-volatile memory which can enlarge its applications segment, due to improved performances, and can fulfil the requirements for future down-scaling. Thermal, electrical and geometrical aspects controlling the functionality of a chalcogenide-based phase change memory cell are analysed. Processing condition effects, material ...

Multi Tunnel Junctions (MTJs) have attracted much attention recently in the fields of Single-Electron Devices (SED) in particular Single-Electron Memory (SEM). In this paper, we have design and study a nano-device structure using a two dimensional array MTJs for Volatile and Non-Volatile-SEM, in order to analyze the impact of physical parameters on the performances. We investigate the single-el...

the affinity of low density lipoprotein (ldl) to its receptor is very important, because most of ldl-uptake pathway is done by the ldl receptor and the change in size of ldl particle and the modification in its components may affects the ldl affinity for its receptor. in this study, the effects of lipophilic agents such as vitamin e and seven volatile oils: anethol, eugenol, geraniol, limonene,...
