normal 0 false false false en-us x-none fa microsoftinternetexplorer4 background: in radiation therapy with ion beams, lateral distributions of absorbed dose in the tissue are important. heavy ion therapy, such as carbon-ion therapy, is a novel technique of high-precision external radiotherapy which has advantages over proton therapy in terms of dose locality and biological effectiveness. metho...
from 1950s onward, new theories and critical approaches burgeoned across humanities. these theories were context-oriented; as a result, the analysis of discursive practices gained significance. thus, social, political, historical and cultural discourses that have been hitherto marginalized and considered inferior to literary texts, were introduced as important texts to be analyzed by critics. o...
We study the interaction between two neutral plane-parallel dielectric bodies in the presence of a highly asymmetric ionic fluid, containing multivalent as well as monovalent (salt) ions. Image charge interactions, due to dielectric discontinuities at the boundaries, as well as effects from ion confinement in the slit region between the surfaces are taken fully into account, leading to image-ge...
Abstract Hofmeister effects, and more generally specific ion are observed broadly in biological systems. However, there many cases where the series might not be followed complex systems, such as channels which can highly to a particular ion. An understanding of how ions from interact with proteinogenic amino acids will assist elucidation why some binding interactions may favoured over others. U...
previous studies have indicated that there may be a relationship between the salivary fluoride concentrations and dental caries while the emphasis was on dental caries in permanent teeth. the aim of this study was to assess the prevalence of dental caries and its predictors in 3-6 year-old children in tehran, iran. the other objective of this investigation was to clarify a relationship between ...
ion molecules with general chemical formula as [li(h2o)] (n=1,2,3), have been chosen as model species toinvestigate the chemical properties of hydrated lithium cations. the rhf(scvs)/ugbs level of calculationhas been used for obtaining equilibrium geometries and rho(r) functions (electron density distributions). by theaid of fundamental physical theorems implemented in quantum theory of atoms i...
The nuclear spin–rotation interaction in the hyperfine structure of the hydrogen molecular ion is investigated. The interaction constants are determined and are found to differ in sign and magnitude compared to another theory, but they are in agreement with some values derived from experiment.

Background: Interaction is considered a necessary, and integral part in all forms of distance learning and web -based learning environments. That how much technologies can support and help interactions is one of the most important issues that should be considered in the web-based environment. These interactions seek to engage students with other students, teachers and also non-human contex...
