Background: The purpose of our study was to evaluate an inexpensive and available method to reduce mucous impactions in mechanically ventilated patients.Methods: This randomized clinical trial was conducted on 40 mechanically ventilated patients aged 15-90 years. The patients were randomly allocated into two arms; 20 cases and 20 controls. The cases received N-acetylcysteine via their nebulizer...

Inhalational insulin was withdrawn from the market due to its potential to produce airway hyper-reactivity and bronchoconstriction. So the present study was designed to explore the acute effects of insulin on airway reactivity of guinea pigs and protective effects of salbutamol and beclomethasone against insulin induced airway hyper-responsiveness on isolated tracheal smooth muscle of guinea pi...

In domains such as robotic rescue, robots must plan paths through environments that are complex and dynamic, and in which robots have only incomplete knowledge. This will normally require both diversions from planned paths as well as significant re-planning as events in the domain unfold and new information is acquired. In terms of a representation for path planning, these requirements place si...

In this paper we present statistical timing driven hMetisbased partitioning. We approach timing driven partitioning from a different perspective: we use the statistical timing criticality concept to change the partitioning process itself. We exploit the hyperedge coarsening scheme of the hMetis partitioner for our timing minimization purpose. This allows us to perform partitioning such that the...

Rectilinear Binary Space Partitioning (BSP) trees are often used for solving various types of range searching problems including ray shooting. We propose a novel method for construction of rectilinear BSP trees for a preferred set of ray shooting queries. Particularly, we study ray sets formed by fixing either the direction or the origin of rays. We analyse and discuss the properties of constru...

In data sequences measured over space or time, an important problem is accurate detection of abrupt changes. partially labeled data, it to correctly predict presence/absence changes in positive/negative regions, both the train and test sets. One existing dynamic programming algorithm designed for prediction unlabeled regions (and ignores labels set); another fitting (but does not changepoints r...

We consider the problem of constructing of binary space partitions (BSP) for a set S of n hyperrectangles in arbitrary dimensional space. If the set S fulfills the low directional density condition defined in this paper then the resultant BSP has O(n) size and it can be constructed in O(n log n) time in R. The low directional density condition defines a new class of objects which we are able to...
