this study was conducted to investigate the effects of applying methods andamount of ammonium polyphosphate (0, 2 and 4 wt%) on fire retardancy andmechanical properties of wood flour/polypropylene composites. the resultsshowed that addition of fire retardant improved the mechanical properties such astensile and flexural strengths and fire retardancy of composites. but by increasingof fire retar...

In this paper, effectiveness of semiconductor optical amplifiers (SOA's) in tree-net in terms of increase in the number of users has been investigated. In the analysis, SOA's with i) unsaturated gain, ii) average gain saturation, and iii) average gain saturation with gain fluctuations have been considered. Further, the results for the tree-net are compared with those for the star network. It is...

Given a family of graphs F , a graph G is F-saturated if no member of F is a subgraph of G, but for all e ∈ E(G), some member of F is a subgraph of G+ e. The saturation number of F , denoted sat(n,F), is the minimum number of edges in an n-vertex F-saturated graph. In this note we determine the saturation number for the family of k-connected graphs.

We study F-saturation games, first introduced by Füredi, Reimer and Seress [1] in 1991, and named as such by West [2]. A graph G is H-saturated if H is not a subgraph of G, but adding any edge to G causes H to be a subgraph. We can ask what the minimum or maximum number of edges in an H-saturated graph on n vertices is they are known as the saturation number and Turán number (extremal number), ...

Table 1. Application of the oxygen section of the NEWS chart to 400 routine observations rounds for 22 patients on a respiratory ward with target oxygen saturation range of 88–92%. SpO2 Number of observations (%) Number with appropriate oximetry score in NEWS (%) Satisfactory 350 (87.5) > 270 had saturation within target range > 80 had saturation >92% breathing air 22/350 (6.3) > 22 had SpO2 ≥9...

The effects of 2 concentrations of kinetin, i.e., 2 and 4 mM together with 2 levels of drought stress, i.e., moderate (35% soil saturation capacity) and severe (20% soil saturation capacity) were investigated on the growth parameters of tomato including fresh and dry leaf weight, leaf number, leaf surface area, fruit number, fruit weight, and enzymatic antioxidants. To this end, first tomato pl...
