The σ(54)-dependent transcription in bacteria requires specific activator proteins, bacterial enhancer binding protein (bEBP), members of the AAA+ (ATPases Associated with various cellular Activities) protein family. The bEBPs usually form oligomers in order to hydrolyze ATP and make open promoter complexes. The bEBP formed by HrpR and HrpS activates transcription from the σ(54)-dependent hrpL ...

The field of Human Computer Interaction (HCI) has become increasingly concerned with user experience. A variety of theoretical accounts of what experience is have been articulated in recent years which offer a number of important insights but it can be unclear how they inform design. While they stress the importance of aspects of experience such as anticipation and reflection they seldom offer ...

in this paper we examine the effect of the oil volatility, consumer price index (cpi) and industrial production on the stock market return in tehran stock exchange (tse). we used seasonal data in period 1378-1390 and auto regressive distributed method (ardl) for the short-term and long-term relationship between the variables. as results of research indicate, we find that there is positive short...

Objetivos. El carcinoma oral de células escamosas (COCE) es una neoplasia maligna que se presenta con frecuencia en hombres adultos. Para determinar el grado histológico existen diversas clasificaciones. Las más utilizadas son la Organización Mundial Salud (OMS) y Anneroth. Por tanto, propósito del estudio preliminar fue haber determinado reproducibilidad los COCE utilizando OMS Anneroth.Método...

We used molecular dynamics to find the average path of the A-domain H → B conformational transition in protein kinase A Iα. We obtained thirteen productive trajectories and processed them sequentially using factor and cross-correlation analyses. The conformational transition is presented as partly deterministic sequence of six events. Event B represents H → B transition of the phosphate binding...

sophisticated SimMan simulator in a course on the treatment of medical emergencies. We do not agree that PowerPoint lectures are in general 'not entertaining'. However, for teaching of drug effects we did set up the new course concept using a simulator because we wanted to implement interactive training. Morgan showed that students significantly rated simulator training as a 'Valuable Learning ...
