background : falls are important causes of mortality and morbidity in urban areas and put a high burden on societies. we investigated patterns of fall traumas and related factors in a referral trauma hospital in tehran, iran. methods: in this routine-data-based study, all documents of fall cases in hazrate-rasool hospital, tehran, iran, during october 2014-2015 were investigated. information on...

OF PH.D. DISSERTATION EVALUATION AND EXPLOITATION OF LOCALITY IN THE DATA DRIVEN EXECUTION MODEL The advent of hybrid von Neumann-data driven architectures arose from a desire to combine the most salient features of coarse grain von Neumann and ne-grain data driven models. Hybrid architectures achieve high performance through concurrent execution and the exploitation of program and data localit...

Wheat (Triticum aestivum L.) is the most important food crop. It offers a great wealth of material for genetic studies due to its wide ecological distribution. The effects of GCA and SCA of morpho-phenological traits i.e. days to emergence, days to flowering, days to maturity, flag leaf length, grain filling duration, spike weight per plant, stem weight and grain yield were studied uti...

We investigate decaying D-branes as the origin of the thermal string gas of string gas cosmology. We consider initial configurations of low-dimensional branes and argue that they can time evolve to thermal string gas. We find that there is a range in the weak string coupling and fast brane decay time regimes, where the initial configuration could drive the evolution of the dilaton to values, wh...

Grazing forages on small-grain fields can be a profitable "second crop" for grain producers and an opportunity for cow-calf producers to retain ownership of weaned calves. The increasing costs of conventional tillage and movement of soil nutrients into surface water creates a need for more sustainable production practices to be incorporated by producers into wheat pasture production systems. Re...

.1 tlcvice is describetl ~vhich effects a continuous separatior~ of intcrnally infestetl wllcat from sound shea at, and ~11ic11 separates ~vheat into a number of fractions of different test weight. A stream of wheat, projected into still air by rapidly moving belts, is dispersed by the conlbined effects of air drag and gravitation into numerous fractions which are caught in a series of hoppers....

Sand pile models are dynamical systems describing the evolution from N stacked grains to a stable configuration. It uses local rules to depict grain moves and iterate it until reaching a fixed configuration from which no rule can be applied. Physicists L. Kadanoff et al inspire KSPM, extending the well known Sand Pile Model (SPM). In KSPM(D), we start from a pile of N stacked grains and apply t...

Agricultural accidents are a frequent cause of severe injury. Sixty-four patients with such injuries were seen from October 1981 through September 1984. The patients ranged in age from 2 to 73 years. The highest incidence of injury occurred during spring planting (May through June) and fall harvesting (September through October). The tractor and grain auger were the most common injuring agents....

A field experiment was conducted to determine the seasonal patterns of arbuscular mycorrhiza (AM) in a dryland winter wheat (Triticum aestivum L.) system and to determine wheat growth and P uptake responses to inoculation with mycorrhizal fungus. Broadcast-incorporated treatments included (1) no inoculation with mycorrhizal fungus, with and without P fertilizer, and (2) mycorrhizal fungal inocu...

We investigate molecular evolution in a star-forming core that is initially a hydrostatic starless core and collapses to form a low-mass protostar. The results of a one-dimensional radiation-hydrodynamics calculation are adopted as a physical model of the core. We first derive radii at which CO and large organic species sublimate. CO sublimation in the central region starts shortly before the f...
