Single crystals of dizinc tellurium dibromide trioxide, Zn(2)(TeO(3))Br(2), were synthesized via a transport reaction in sealed evacuated silica tubes. The compound has a layered crystal structure in which the building units are [ZnO(4)Br] distorted square pyramids, [ZnO(2)Br(2)] distorted tetra-hedra, and [TeO(3)E] tetra-hedra (E being the 5s(2) lone pair of Te(4+)) joined through sharing of e...

Marek's disease virus (MDV) is one of the most oncogenic herpesviruses and induces T lymphomas in chickens within weeks after infection. Only a limited number of viral transcripts are detected in MDV tumor samples and cell lines. One of the major transcripts encodes MEQ, a 339-amino-acid bZIP protein which is homologous to the Jun/Fos family of transcription factors. The C-terminal half of MEQ ...

Abstract: A 2-rainbow domination function of a graph G = (V, E) is a function f mapping each vertex v to a subset of {1, 2} such that ⋃ u∈N(v) f (u) = {1, 2} when f (v) = �, where N(v) is the open neighborhood of v. The weight of f is denoted by wf (G) = ∑ v∈V �f (v)�. The 2-rainbow domination number, denoted by r2(G), is the smallest wf (G) among all 2-rainbow domination functions f of G. The ...

Benzoquinone reductase (BR; EC 1.6.5.7) is an enzyme which catalyzes the bivalent redox reactions of quinones without the production of free radical intermediates. Using 2D-PAGE comparisons, two proteins were found to be up-regulated in wild-type cotton ovules during the fiber initiation stage but not in the fiberless line SL 1-7-1. These proteins were excised from the gel, partially sequenced ...

Valence excitation spectra for the linear isomers of He-, Ne-, and Ar-Br2 are reported and compared to a two-dimensional simulation using the currently available potential energy surfaces. Excitation spectra from the ground electronic state to the region of the inner turning point of the Rg-Br2 (B,nu') stretching coordinate are recorded while probing the asymptotic Br2 (B,nu') state. Each spect...

This paper aims to evaluate the simultaneous adsorption of basic red 2 (BR2) and violet 3 (BV3) in a binary system batch mode using date stones as low cost adsorbents. For both dyes, experimental kinetic data were well fitted by Brouers–Sotolongo model (R =0.99) intraparticle diffusion was controlling step mass transfer mechanisms. The extent found be lower for BR2 (1.13×10 -11 cm /s) than BV3 ...

Cationic dye - basic red 2 (BR2) was removed from aqueous solutions by sulfuric acid activated waste Gossypium hirsutum seeds (WGSAB). The main and interactive effects of five process variables such as, adsorbent dose (1.25 – 5 g/L), initial dye concentration (100–300 mg/L), contact time (1–3 h),  pH (2 – 12) and temperature (20 – 400C) were investigated via  response su...

The structure and composition of bromine clathrate hydrate has been controversial for more than 170 years due to the large variation of its observed stoichiometries. Several different crystal structures were proposed before 1997 when Udachin et al. (Udachin, K. A.; Enright, G. D.; Ratcliffe, C. I.; Ripmeester, J. A. J. Am. Chem. Soc. 1997, 119, 11481) concluded that Br2 forms only the tetragona...

Biotechnologies are a feasible alternative for indoor air pollutant abatement. Among biotechnologies, bioactive coatings consist of microorganisms embedded in polymeric matrices, allowing direct contact between and gas pollutants, thus enhancing their Three bioreactors (BR1, BR2 BR3) were inoculated with VOC-degrading enriched culture, latex coating the fresh activated sludge. The influence emp...
