in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
The reliability of consecutive-k-out-of-n: F system (or C(k, n: F) system) has aroused great interest since it was first studied by Kontoleon in 1980 [1]. The system consists of a sequence of n ordered components along a line such that the system fails if and only if at least k consecutive components in the system have failed. A list of typical applications of C(k, n: F) system was given by Yam...
The effects of substituents on the symmetry and the nature of halogen bonds in [N∙∙∙X∙∙∙N]+-type systems are presented for the YC5H4N∙∙∙X∙∙∙NC5H5 (Y = NO2, CN, H, CH3, OCH3, OH, NH2, X = Cl, Br, I) complexes. Some structural parameters, energy data and electronic properties were explored with...

Graphene oxide nanosheet (GONS) can be a suitable membrane for gas separation with high permeability and selectivity. Separation of N2/CO2 using functionalized GONS was investigated by molecular dynamics simulations. The simulated systems were comprised of two types of GONS with a pore in their center, N2 and CO2 molecules. The selectivity and ...
A preliminary analysis of the posbist reliability of typical system structures was provided by Cai et al. [Fuzzy Sets and Systems 42: 145–172 (1991) and Microelectronics and Reliability 35(1): 49–56 (1995)]. In this paper, we provide a detailed analysis of the posbist reliability of k-out-of-n:G system structures. Expressions of the posbist reliability of k-out-of-n:G system is developed. It is...
we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
Aqueous two-phase systems (ATPS) have emerged as a powerful extraction method for the downstream processing of bio-molecules. The aim of this work was to investigate the possibility of utilizing ATPS for the separation of recombinant Bacillus sphaericus phenylalanine dehydrogenase (PheDH). Polyethylene glycol (PEG) and ammonium sulfate systems were selected for our experi...
