Submitted for the MAR14 Meeting of The American Physical Society Phonon assisted carrier motion on the Wannier-Stark ladder ALFRED CHEUNG, MONA BERCIU, Univ of British Columbia — It is well known that at zero temperature and in the absence of electron-phonon coupling, the presence of an electric field leads to localization of carriers residing in a single band of finite bandwidth. In this talk,...

Streptomycetes have high biotechnological relevance as producers of diverse metabolites widely used in medical and agricultural applications. The biosynthesis of these metabolites is controlled by signalling molecules, γ-butyrolactones, that act as bacterial hormones. In Streptomyces coelicolor, a group of signalling molecules called SCBs (S. coelicolorbutanolides) regulates production of the p...

The purpose of this study is to evaluate and suggest priorities for policy implementation improve the management system environment self-contained breathing apparatus (SCBA) charging rooms used by firefighters. included 15 experts three interviews, two modified Delphi surveys were conducted. Based on results previous research expert environmental improvement plan SCBA first derived. was present...

Abstract We theoretically address the impact of a random distribution non-magnetic impurities on electron states formed at surface topological insulator. The interaction electrons with is accounted for by separable pseudo-potential method that allows us to obtain closed expressions density states. Spectral properties are assessed means Green’s function averaged over disorder realisations. For c...

In this study we investigate the effect of random point disorder on surface states a topological insulator with out-of-plane magnetization. We consider within high order Born approximation. The series converges to one branch self-consistent approximation (SCBA) solution at low disorder. As strength increases, another SCBA finite density magnetization induced gap. Further increase leads divergen...

In current research, the social return to citizens initiatives is important but often under-evaluated. Within this work, we collected information that has emerged from measuring value of regenerative projects in shrinking cities. We used a case study project Gebrookerbos, socio-spatial regeneration city Heerlen, Netherlands. To assess project’s monetary and immaterial aspects, cost–benefit anal...

Sugarcane bagasse ash (SCBA), a biomass waste resulting from sugarcane burning for electricity production, has shown to be viable alternative option as partial cement replacement due its chemical composition and physical properties. Besides, previous research indicates that higher curing temperature may improve the mechanical properties of mixes containing SCBA replacement. However, environment...
