el-jardali and fadllallah provide an excellent summary of the many dimensions of knowledge use, and the breath of issues and activities that must be considered if knowledge is to be put into practice. however, reliance on a continuum (rather than a cyclical, multidirectional, systems) model creates a number of limitations, particularly when promoting evidence-informed action in the areas of hea...

The integrity of inspiratory and expiratory unidirectional valves is very important in the normal functioning of an anesthetic circle breathing system. We describe our experience of an emergency manipulation of a ceramic valve disk of a circle breathing system (Dräger Fabius GS, Dräger Medical Inc) that altered its characteristics and led to rebreathing only during spontaneous ventilation.

Assume that we measure a physical ~mntity x with a measuring device whose accuracy is ~ (i.e., whose prtniucers guarantee that the difference a: ~ between the actual value :r and the measured value d{ms m~t exceed 5). If the result of this measurement is ~, then Ix~ssible values of a: fiwm an interval [~-~,~+~]. Suppose nnw that we know that a physical qtiantity y is a function of the physical ...

The behavioural manipulation hypothesis posits that parasites can change the behaviour of hosts to increase the reproductive fitness of the parasite. The protozoan parasite Toxoplasma gondii fits this description well. Sexual reproduction occurs in the cat intestine, from which highly stable oocysts are excreted in faeces. Grazing animals, including rodents, can then ingest these oocysts. The p...

(a) If we consider the intersections of the circle Hi(O) (center Hi and radius HiO) with the line Ai+1Ai+2, then we obtain six points which all lie on a circle with center H (first Droz-Farny circle). (b) If we consider the intersections of the circle Mi(H) (center Mi and radius MiH) with the line AiAi+1, then we obtain six points which all lie on a circle with center O (second Droz-Farny circl...

We present a method for estimating the domain of attraction of the origin for a system under a saturated linear feedback. A simple condition is derived in terms of an auxiliary feedback matrix for determining if a given ellipsoid is contractively invariant. This condition is shown to be less conservative than the existing conditions which are based on the circle criterion or the vertex analysis...

The article explores a field quite new for Russian religious studies: research into the infosphere of institutions. In our case, term “infosphere” defines totality institutions and informational resources various origin, as well channels communications, including verbal communication, those providing development this infosphere. At that, we rely on works by one creators contemporary philosophy ...

Long branch attraction is a problem that afflicts phylogenetic methods and a procedure to detect a data set suffering from this problem is the long branch extraction method[1]. This method has been well cited and used by many authors for their analysis but no strong validation has been performed as to its accuracy. We performed such an analysis by an extensive search of the branch length search...
