let $g$ be a finite group‎. ‎a subgroup‎ ‎$h$ of $g$ is called an $mathcal h $ -subgroup in‎ ‎$g$ if $n_g (h)cap h^gleq h$ for all $gin‎ ‎g$. a subgroup $h$ of $g$ is called a weakly‎ $mathcal h^ast $-subgroup in $g$ if there exists a‎ ‎subgroup $k$ of $g$ such that $g=hk$ and $hcap‎ ‎k$ is an $mathcal h$-subgroup in $g$. we‎ ‎investigate the structure of the finite group $g$ under the‎ ‎assump...

UCN-01 is a derivative of staurosporine, initially developed as a potentially selective inhibitor of the Ca(2+)- and phospholipid-dependent protein kinase C, but with the capacity to inhibit a number of tyrosine and serine/threonine kinases. UCN-01 inhibits the growth of 5 breast carcinoma cell lines with a 50% inhibitory concentration range of 30-100 nM during 6 days of continuous exposure. In...

After 1 h alkaline oxygen evolution reaction (OER), intermetallic Fe6Ge5 forms a core–shell structure that collapses under continuous OER revealing structures can be only snapshots on pathway to full precatalyst transformation.

Abstract Many types of sustainably-prepared functional biochar catalysts are needed to transform biomass substrates into platform chemicals. In this work, weak-acid were prepared by mix ball-milled (10 min, isothermal, room temperature) cherry blossom tree leaf (BM) with humic acid (H) prior carbonization samples for 1 h under nitrogen gas. Characterization the as-prepared materials (HBM-carbon...

helicobacter pylori is the causative agent of gastritis and peptic ulcer disease. eradication of h. pylori is hard to achieve and often require multiple antibiotics regimens. these regimens are quite expensive and have substantial side effects. licorice is a traditional drug which is frequently used for gastric discomforts in iran. the susceptibility of h. pylori to the extract of licorice has ...

it is necessary to determine the amount of chilling requirement of present cultivars and also to produce new low chill cultivars through breeding programs because of the global warming phenomenon and tendency to grow temperate fruit in warm climate. in this study, the amount of chilling requirement in ‘askari’, ‘rotaby’, ‘yaghuty’, ‘rish baba’ and ‘monaga΄ were evaluated. uniform cuttings of me...

The potent induction of hepatic cytochrome P450 3A isoforms by rifampin complicates therapy for coinfection with human immunodeficiency virus (HIV) and Mycobacterium tuberculosis. We performed an open-label, single-arm study to assess the safety and pharmacokinetic interactions of the HIV protease inhibitor atazanavir coadministered with rifampin. Ten healthy HIV-negative subjects completed pha...

flow visualization techniques using tracer markers such as die, smoke, hydrogen bubbles, etc., have been widely used in experimental investigations of large scale structures of a variety of flow fields. they have played an important role in understanding the physics of the coherent structures formation and evolution in the transitional as well as the turbulent regions of the flow fields. howeve...
