background & aim: the essential oils are the most important secondary aromatic biochemical compounds in plants and even in some animals. they are of great importance because of their aromatic, flavoring and preventing properties from deterioration in food industries. according to ethnobotany study of aerial parts of bakhtiari celery or kelus (kelussia odoratissma  mozaffarian) in dairy such...

• Lambert-W function-based MOSFET parameter extraction down to cryogenic temperature. modeling of drain current characteristics using classical mobility law 4.2 K. Main FDSOI parameters extracted versus temperature and gate length. Mobility degradation at short channel length due increased neutral defect scattering. The applicability the methodology is demonstrated for 28 nm MOSFETs deep temper...

Inspired by the LHCb's observations of hidden-charm $P_{c(s)}$ states, we study their hidden-strange analogues $P_s$ states in both $[udu][\bar ss]$ and $[uds][\bar su]$ configurations. We investigate pentaquark $p\eta^\prime$, $p\phi$, $\Lambda K$, $\Sigma K$ $\Sigma^\ast K^\ast$ structures with $J^P = \frac{1}{2}^-$ ^\ast \frac{3}{2}^-$, calculate masses framework QCD sum rules. Our numerical...

We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...

The nonleptonic decays ${B}_{d,s}\ensuremath{\rightarrow}{K}^{*0}{\overline{K}}^{*0}$ are reanalyzed in perturbative QCD approach, which is based on the ${k}_{\mathrm{T}}$ factorization. In Standard Model, calculated branching fraction and longitudinal polarization of ${B}_{d}\ensuremath{\rightarrow}{K}^{*0}{\overline{K}}^{*0}$ agreement with experimental measurements, while predictions ${B}_{s...

background and objectives: ziziphora clinopodioides is a perennial herb and grows widely in west and northwest of iran. the aerial parts are used as appetizer, carminative and antiseptic as well as for the treatment of medical conditions such as high blood pressure, asthma hyperhidrosis, palpitation and insomnia methods: the aerial parts of ziziphora clinopodioides lam. were extracted by ethano...

Aim In this study we attempt to indicate anti-carcinogenic influence of ether extracted metabolites of Streptomyces Levis sp. on gene expression in colon cancer. Background Colon cancer is one of the most prevalent cancers worldwide. In recent decades, researchers have been seeking the treatment for cancer. Natural products are valuable compounds with fewer side effects in comparison to chemo...

This paper presents a new method of developing a large-scale hyponymy relation database by combining Wikipedia and other Web documents. We attach new words to the hyponymy database extracted from Wikipedia by using distributional similarity calculated from documents on the Web. For a given target word, our algorithm first finds k similar words from the Wikipedia database. Then, the hypernyms of...

Auto-catalyzed hydrothermal pretreatment (A-HTP) and sulfuric-acid-catalyzed (SA-HTP) were applied to quinoa stalks in order reduce their recalcitrance towards enzymatic saccharification. Prior pretreatment, extracted with either water or a 50:50 (v/v) ethanol–water mixture for removing saponins. Extraction aqueous ethanol, respectively, led removal of 52 75% (w/w) the saponins contained raw ma...
