Injuries caused by traffic accidents cause many deaths and disabilities children. Road traffic injuries are the main cause of death between the ages of 15 and 19 years and is the second cause of death among 5 to 14 year olds. Children's attitudes about driving and safe use of roads formed in 11 years. Road traffic injuries is one of the five cause of disability among children. Most victims betw...

this paper consider the   general  forms of $(alpha,beta)$-fuzzyleft ideals (right ideals, bi-ideals, interior ideals) of an orderedsemigroup, where$alpha,betain{in_{gamma},q_{delta},in_{gamma}wedgeq_{delta}, in_{gamma}vee q_{delta}}$ and $alphaneqin_{gamma}wedge q_{delta}$. special attention is paid to$(in_{gamma},ivq)$-left ideals (right ideals, bi-ideals, interiorideals) and some related  pr...

We investigated the ecological physiology and behavior of free-living wood frogs [Lithobates (Rana) sylvaticus] overwintering in Interior Alaska by tracking animals into natural hibernacula, recording microclimate, and determining frog survival in spring. We measured cryoprotectant (glucose) concentrations and identified the presence of antifreeze glycolipids in tissues from subsamples of natur...

Some results relating to the road-coloring conjecture of Alder, Goodwyn, and Weiss, which give rise to an O(n2) algorithm to determine whether or not a given edge-coloring of a graph is a road-coloring, are noted. Probabilistic analysis is then used to show that, if the outdegree of every edge in an n-vertex digraph is δ = ω(logn), a road-coloring for the graph exists. An equivalent re-statemen...

The Tanana River flows through interior Alaska, a region characterized by discontinuous permafrost. Studies link degrading permafrost to increased winter river discharge due to greater groundwater (GW) recharge increasing GW input to river baseflow. In winter, interior Alaskan rivers are exclusively fed by GW, which provides an external source of heat. In fact, some portions of rivers fed by GW...

objectives this study aimed to measure road traffic fatality rates and years of lost life, and also to depict a view of trends in road traffic deaths from 2004 to 2010 in yazd city, a province in central iran. materials and methods this retrospective case study analyzed road traffic deaths that were classified under the v01 - v99 codes of the icd-10 in yazd province from march 2004 to march 201...

The efficacy of hydrodynamic pressure (HDP) treatment for inactivation of Escherichia coli O157:H7 in blade-tenderized beef steaks was studied. Beef steaks (N = 48) were inoculated with a five-strain cocktail of Escherichia coli O157:H7 and treated with blade tenderization (BT), HDP or a combination of BT followed by HDP (BTH). Control and treated steaks were cooked to 54.4C (undercooked), 62.8...
