The introduction and rapid spread of Drosophila subobscura in the New World two decades ago provide an opportunity to determine the predictability and rate of evolution of a geographic cline. In ancestral Old World populations, wing length increases clinally with latitude. In North American populations, no wing length cline was detected one decade after the introduction. After two decades, howe...

For the major organizations, businesses and government agencies the biggest constraints are cost, schedule, reliability, and quality for a given software product. And hence, more and more emphasis is put on software processes asking software engineers to follow it. The goal of this paper is to present a modified software process model using the Personal Software Process SM (PSP), Team Software ...

High-latitude reefs support unique ecological communities occurring at the biogeographic boundaries between tropical and temperate marine ecosystems. Due to their lower ambient temperatures, they are regarded as potential refugia for tropical species shifting poleward due to rising sea temperatures. However, acute warming events can cause rapid shifts in the composition of high-latitude reef co...

Ground-based very low frequency (VLF) radio propagation in the Earth-ionosphere waveguide has enabled extensive electron number densities D region of Earth's ionosphere to be determined, by day typically below heights 70–80 km and night height range ?75–90 km. Many rocket-based density measurements have also been reported literature from ?60 upwards using current probes, at a few MHz between ro...

Climate change is expected to have stronger effects on water resources in higher latitude regions. Despite intensive research on possible hydrological responses in those regions to a warmer environment, our knowledge on erosion and sediment yield induced by the climate change in high-latitude headwaters is still limited. In this study, we estimated suspended sediment yields from 2021 to 2050 in...

Due to rapid technology progress, there has been a significant increase in design complexity, decrease in time-to-market, and growing demand for embedded systems. Further, with the integration of computer technology, consumer products, and communication facilities, the software in an embedded system now accounts for as much as 70% of total system functionalities. Though there are some tools ava...

background: previous studies have shown morphological changes after intra peritoneal drug administration in human and animals. this study examines the effect of intrapretoneal nicotine administration on pyramidal neurons in area ca1of hippocampus. methods: the study included male wistar rats with the mean weigh of 220-250 g. nicotine was administered at a dose of 0.4 and 1.5 mg/kg, each for a p...

The Grid has the potential to grow significantly over the course of the next decade and therefore the mechanisms that make the Grid possible need to become more efficient in order for the Grid to scale. One of these mechanisms revolves around resource management; ultimately, there will be so many resources in the Grid, that if they are not managed properly, only a very small fraction of those r...

The studied region in this research (Alborz province) is structurally located in Alborz poly_orogenic system of northern Iran. The purpose of this research is combining the remote sensing and geology sciences to show fault lineaments by analyzing satellite data in a vast region and also comparison between lineaments layer and recognized faults in geology maps. Firstly, two scenes of Landsat ETM...
