sahand volcanic-sub-volcanic dome, along with several other magmatic domes in northwest iran and the southern part of tabriz fault show adakitic geochemical characteristics. sahand dome has mainly dacitic composition. the sio2 content and mg number of sahand dome range from 64 to 73 wt% and 27 to 57 respectively. sahand dome can be classified as high silica adakitic (hsa) type. the rocks studie...

BACKGROUND This paper aims at assessing the effectiveness of the package of road safety measures implemented after road safety was included in the political agenda in the year 2004 on the number of road traffic-injured people in Spain. METHODS An evaluation study was performed using an interrupted time-series design. The study population was people injured in road traffic crashes in Spain bet...

The objective is to find the impact speeds of two motor vehicles involved in a traffic crash. calculations take into account approach (pre-collision) and departure (post collision) angles, as well weights post collision both vehicles. data provided by Timothy Sleyzack who investigated this collision. conclusions confirm validity use Conservation Linear Momentum field crash reconstruction.

The end-Triassic extinction is characterized by major losses in both terrestrial and marine diversity, setting the stage for dinosaurs to dominate Earth for the next 136 million years. Despite the approximate coincidence between this extinction and flood basalt volcanism, existing geochronologic dates have insufficient resolution to confirm eruptive rates required to induce major climate pertur...

[1] Abstract: The subducting Nazca Plate shows a high degree of along-strike heterogeneity in terms of intermediate-depth seismicity ( 70–300 km), orientations of slab stress, and volcanism. We compile the intermediate-depth earthquakes of South America from the Harvard Centroid Moment Tensor (CMT) catalogue to determine along-strike dip variations, and we explore the variable level of correlat...

in the central iranianvolcanic belt (civb), north-west of shahre-babak, in the area of javazm, dehaj and khabr, about 60 subvolcanic porphyritic dacitic to rhyodacitic domes (1-10 km2) are intruded into a variety of rock sequences from mesozoic to early miocene in age. these rocks are a part of dehaj-sardoieh belt. the civb contains intrusive and extrusive rocks of cretaceous-quaternary age. ge...

We study the collision of a DNA or other polyelectrolyte chain with a point obstacle in the presence of an electric field via computer simulation. We find a very strong dependence of the average collision time, ktcl, and the average distance traveled during a collision, kzcl, upon the impact parameter, b. Despite the complexities of the chain-post interaction, ktcl and kzcl follow universal cur...

We study characteristic schemes for a model problem for the Fermi pencil beam equation. The objective is twofold: (i) To design eecient and accurate numerical schemes based on the principle of solving a particle transport problem, exactly, on each collision free spatial segment combined with a projection on each collision site, from a pre collision angle and energy coordinates (AE) to a post co...

The post-collisional Syunik and Vardenis volcanic highlands, located in the southern Lesser Caucasus mountains (part of Arabia-Eurasia collision zone) are host to over 200 monogenetic volcanoes, as well 2 large Quaternary polygenetic volcanoes highland. latter overlain by lavas from suggesting there was a transition style activity large-volume central vent eruptions dispersed small-volume erupt...
