In the context of bosonic string theory, we shall extract general radiation amplitude a massless closed from interaction two parallel unstable D$p$-branes. The branes are non-stationary and have been dressed by background fields. foregoing will be rewritten for state with large distance. Besides, study gravitational dilatonic radiations this configuration.

It is easy to deal with a Venn Diagram for 1 ≤ n ≤ 3 sets. When n gets larger, the picture becomes more complicated, that's why we thought at the following codification. That’s why we propose an easy and systematic algebraic way of dealing with the representation of intersections and unions of many sets. Introduction. Let's first consider 1 ≤ n ≤ 9, and the sets S1, S2, ..., Sn. Then one gets 2...

Fenokinoshitalite, ideally BaFe2+3(Si2Al2)Ot0(OH)2, is the iron-rich analogue of kinoshitalite, and thus a new species of the brittle mica group. Samples commonly have considerable chemical substitutions, with large cations (e g., K, Na) for Ba, mediumsize cations (e.g., Mg, Mn, Ti, Al, Fe3*) in octahedral sites, and F for OH. The color is dark green, the luster is vitreous, thin grarns are tra...

In this paper we prove a special case of the transversal conjecture of Tverberg and Vrećica. We consider the case when the numbers of parts ri in this conjecture are powers of the same prime. We also prove some results on common transversals that generalize the classical nonembeddability theorems. We also prove an analogue of colored Tverberg’s theorem by Živaljević and Vrećica. Instead of mult...

Silicon microphotonics has emerged as the leading technology to overcome the interconnect bottleneck that limits a further increase of computation power following Moore's law. Optical interconnects between different electronic microprocessors in an electronic-photonic integrated circuit (EPIC) can provide a fast, low-loss and highbandwidth alternative to electrical interconnects, which suffer f...

abstract in the recent decades, application of geostatistic and remote sensing for mapping salinity and sodicity of surface soil and monitoring it's changes have been developed. the goal of this research was to compare the capability of geostatistic and remote sensing methods for mapping salinity-sodicity of soils in playa from sourthern mah valat county, in the khorasan razavi province. 88 sam...

Software is an integral enabler of computation, experiment and theory and a primary modality for realizing NSF's Cyberinfrastructure Framework for 21st Century Science and Engineering (CIF21) vision 1. Scientific discovery and innovation are advancing along fundamentally new pathways opened by development of increasingly sophisticated software. Software is also directly responsible for increase...

The influence of aqueous silica on gallium(III) hydrolysis in dilute (2 10 4 mGa 5 10 ) and moderately concentrated (0.02 mGa 0.3) aqueous solutions was studied at ambient temperature, using high resolution X-ray absorption fine structure (XAFS) and nuclear magnetic resonance (NMR) spectroscopies, respectively. Results show that, in Si-free acidic solutions (pH 3), Ga is hexa-coordinated with o...

A cross-sectional analytic study of 190 hill-tribe youth in a community in the north of Thailand was conducted to investigate the sero-prevalence of HAV and factors related to positive anti-HAV antibody. The studied youth, whose ages ranged from 15 to 24 years, were interviewed about socio-economic status and personal hygiene. Blood specimens were collected to detect antiHAV by ELISA commercial...

In this paper, we study the existence of minimizers Sobolev quotient for a class nonlocal operators with an orthotropic structure having different exponents integrability and orders differentiability. Our method is based on concentration-compactness principle which extend to operators. One consequence our main result nontrivial nonnegative solution corresponding critical problem.
