Through study of observations and coupled climate simulations, it is argued that the mean position of the Inter-Tropical Convergence Zone (ITCZ) north of the equator is a consequence of a northwards heat transport across the equator by ocean circulation. Observations suggest that the hemispheric net radiative forcing of climate at the top of the atmosphere is almost perfectly symmetric about th...

Amajor challenge in nanotechnology is to precisely transport a nanoscale object from one location on a nanostructure to another location along a designated path. The successful construction of self-assembled DNA nanostructures provides a solid structural foundation to meet this challenge. DNA, with its immense information-encoding capacity and welldefinedWaston–Crick complementarity, has been e...

A climate model that includes a coupled ocean biogeochemistry model is used to define large oceanic biomes in the North Pacific Ocean and describe their changes over the 21st century in response to the IPCC Special Report on Emission Scenario A2 future atmospheric CO2 emissions scenario. Driven by enhanced stratification and a northward shift in the mid-latitude westerlies under climate change,...

C W. A. V. and H Y. (2004) Linking migration and mobility: individual and contextual effects in housing markets in the UK, Regional Studies 38, 617–628. Most migration work continues to separate longand short-distance moves and their outcomes, but clearly, they are part of a complex process of relocation across different scales. While we know that long-distance moves are largely driven ...

type e hepatitis is caused by an unclassified virus producing acute self-limited hepatitis in different parts of the world. in order to estimate the prevalence of hepatitis e virus seropositivity in tehran blood donors, a cross– sectional study was performed by the enzyme immunoassay method from 2003 to 2004 in a group of 90 blood donors. we noticed that 7 cases (7.8%) were anti-hev ab positive...

the present study aimed to investigate the generic organization of research article introductions in local iranian and international journals in english for specific purposes, english for general purposes, and discourse analysis. overall, 120 published articles were selected from the established journals representing the above subdisciplines. each subdiscipline was represented by 20 local and 2...
