background: routine repeat testing of critical laboratory values is very common these days to increase their accuracy and to avoid reporting false or infeasible results. we figure that repeat testing of critical laboratory values has any benefits or not.   methods : we examined 2233 repeated critical laboratory values in 13 different hematology and chemistry tests including: hemoglobin, white b...

there remains a conviction that the torrent of publications and the financial outlay on leadership development will create managers with the skills and characters of perfect leaders, capable of guiding healthcare organisations through the challenges and crises of the 21st century. the focus of much attention continues to be the search for the (illusory) core set of heroic qualities, abilities o...

the quantitative structure-property relationship (qspr) method is used to develop the correlation between structures of refrigerants (198 compounds) and their critical temperature. molecular descriptors calculated from structure alone were used to represent molecular structures. a subset of the calculated descriptors selected using a genetic algorithm (ga) was used in the qspr model development...

in order to present a quantitative indicator for the onset of instability, in this paper, the critical points of a stratified gravitational flow on a slope are found and analyzed. these points are obtained by means of the solution of the two-dimensional navier-stokes equations via the standard arakawa-c finite-difference method. results show that in the marginal richardson numbers, the critical...

objectives: behavioral-based safety is a term used to describe the prevention of accidents, injuries and loss in the workplace. an effective behavior-based safety program relies on engaging employees to understand how unsafe behaviors lead to injuries and how to eliminate them from the workplace. this paper examines behavior-based safety program in a massive construction site. methods: for this...

In this paper we give a characterization of critical configurations for projective reconstruction with any number of points and views. A set of cameras and points is said to be critical if the projected image points are insufficient to determine the placement of the points and the cameras uniquely, up to a projective transformation. For two views, the critical configurations are well-known. In ...

In this paper some critical aspects of the behaviour of breaking lattices subject to slow driving forces are briefly reviewed. In particular, fluctuations in the response to external solicitations are discussed.
