The chemical composition of the essential oil of fruits of Pimpinella haussknechtiiBoiss.was studied by GC-MS. After GC-MS analysis, one unknown component (56.7%) was observed, which was not characterized in the GC-MS library. The essential oil of P.hauskenekhtii was injected to HPLC using YMC-Pak-Sil column (250 × 20 mm) with gradient system of hexane (A), and hexane: ethyl acetate, 9:1 (B) to...

Background & Aim: Artemisia species with common Persian name of Dermaneh are found all over Iran and are used for treatment in infectious diseases such as malaria, hepatitis and other diseases. Some Artemisia species are used in traditionally as tonic and anti-helmintic in north of Iran. Artemisia haussknechtii is used in dyspepsia and other gastroint...

Controlled frames in Hilbert spaces have been recently introduced by P. Balazs and etc. for improving the numerical efficiency of interactive algorithms for inverting the frame operator. In this paper we develop a theory based on g-fusion frames on Hilbert spaces, which provides exactly the frameworks not only to model new frames on Hilbert spaces but also for deriving robust operators. In part...

This documentation is designed to serve as a user s manual for Signal and Sigali It explains how one can use Signal and Sigali from scratch without any previous knowledge about the architecture of either of them Signal is the compiler of a synchronous data ow language of the same name This language is used for precise speci cation of real time reactive discrete event systems When used with one ...

The study of the complexity of logical problems has provided a very fruitful field of research since many decades. On the one hand researchers have tried to classify exactly in terms of complexity classes and upper and lower bounds the complexity of decision and other logical problems. Although in general such problems are of high complexity, efforts have been made to develop efficient algorith...
