blood pressure assessed by ABPM and the average reading of systolic blood pressure assessed by the cardiovascular technician was 2.8 mmHg with a white lab coat, and –1.8 mmHg without a white lab coat (P<0.001). This suggests that blood pressure recordings are most erroneous when done by a physician, than by a nurse, and most closely match the gold standard of ABPM when done by a cardiovascular ...

In diagnosing a failed system, a smart technician would choose tests to be performed based on the context of the situation. Currently, test program sets do not fault-. isolate within the context of a situation. Instead, testing follows a rigid, predetermined, fault-isolation sequence that is based on an embedded fault tree. Current test programs do not tolerate instrument failure and cannot red...

This is a qualitative, exploratory and descriptive study whose general objective was to learn, considering the perspective of the nursing technician who works in school hospitals, the competencies developed during their educational process to implement the Nursing Care Systematization (NCS). Data collection and analysis were carried out through a focal group, with content analysis and nursing t...

F rom fl attened epithelial cells to elongated neurons, cell morphology is heavily intertwined with cell growth and function. Understanding the genetic factors that govern cell shape might therefore provide insights into the processes underlying development and disease. Amy Kiger has focused on these and other fundamental questions of cell biology in Drosophila throughout her career. She fi rst...

It is well known that Russell abandoned his multiple-relation theory of judgment, which provided the philosophical foundations for PM ’s ramified typetheory, in response to criticisms by Wittgenstein. Their exact nature has remained obscure. An influential interpretation, put forth by Sommerville and Griffin, is that Wittgenstein showed that the theory must appeal to the very hierarchy it is in...

Since at least half of the d edges incident to a vertex u of a simple d-polytope P either all point “up” or all point “down,” v must be the unique “bottom” or “top” vertex of a face of P of dimension at least d/2. Thus the number of P’s vertices is at most twice the number of such high-dimensional faces, which is at most Ed,2 $ iG &Ynu) = O(nld/‘l), if P has n facets. This, in a nutshell, provi...

This paper introduces a new and simple statistic on noncrossing partitions that expresses each coordinate of the toric h-vector of a cubical complex, written in the basis of the Adin h-vector entries, as the total weight of all noncrossing partitions. The same model may also be used to obtain a very simple combinatorial interpretation of the contribution of a cubical shelling component to the t...

We use Klee’s Dehn-Sommerville relations and other results on face numbers of homology manifolds without boundary to (i) prove Kalai’s conjecture providing lower bounds on the f -vectors of an even-dimensional manifold with all but the middle Betti number vanishing, (ii) verify Kühnel’s conjecture that gives an upper bound on the middle Betti number of a 2k-dimensional manifold in terms of k an...
