Background: Co(II) constitutes a part of vitamin B12, hence, it is necessary for human health. However, at concentrations higher than the permissible limits, humans and animals suffer adverse chronic effects. It is necessary to reduce the concentration to a permissible level. In the present study, pre-purification and thermal modification of chicken’s feather increased their porosity and ...

Manganese (Mn(2+))-, zinc (Zn(2+))- and copper (Cu(2+)) play significant roles in transcriptional gene regulation, physiology, and virulence of Streptococcus pneumoniae. So far, the effect of the important transition metal ion cobalt (Co(2+)) on gene expression of S. pneumoniae has not yet been explored. Here, we study the impact of Co(2+) stress on the transcriptome of S. pneumoniae strain D39...

Williams (2011), " Service dominant logic and its implications for tourism management: the co-production of innovation in the hotel industry " , Tourism Abstract This paper introduces the concept of service-dominant logic as a research paradigm in marketing management. It does so in the context of tourism management " s need to engage with wider debates within the mainstream management literatu...

The title compound, [Co(SO(4))(C(10)H(8)N(2))(2)]·C(2)H(6)O(2), has the Co(2+) ion in a distorted octa-hedral CoN(4)O(2) coordination geometry. A twofold rotation axis passes through the Co and S atoms, and through the mid-point of the C-C bond of the ethane-diol mol-ecule. In the crystal, the [CoSO(4)(C(10)H(8)N(2))(2)] and C(2)H(6)O(2) units are held together by a pair of O-H⋯O hydrogen bonds.

Clean hydrogen is the major energy carrier for power production. The conversion of CO to CO2 and zero emission during hydrogen energy production causes high capital cost. It is a matter of prestige to optimize the process in order to make zero emission and cost effective production of clean hydrogen energy and electric power. In this era, coal gasification is th...

A $Gamma$-so-ring is a structure possessing a natural partial ordering, an infinitary partial addition and a ternary multiplication, subject to a set of axioms. The partial functions under disjoint-domain sums and functional composition is a $Gamma$-so-ring. In this paper we introduce the notions of subdirect product and $(phi,rho)$-product of $Gamma$-so-rings and study $(phi,rho)$-represen...

N,C,S-pincer iron(III) carbonyl complexes with two phosphorus ligands—trans-[Fe(L-κ3N,C,S)(CO)(PR3)2]PF6 ([1]PF6, R = Me; PF6, OEt) are light-inducible CO releasers under ambient conditions. Optical wavelength ranges corresponding to such a release depend on the phosphorous ligands. Complex [1]PF6 responds light wavelengths shorter than 500 nm, while photosensitivity of [2]PF6 is extended up 80...

The novel hydroxylamine derivative, bimoclomol, has been shown previously to act as a co-inducer of several heat shock proteins (Hsp-s), enhancing the amount of these proteins produced following a heat shock compared to heat shock alone. Here we show that the co-inducing effect of bimoclomol on Hsp expression is mediated via the prolonged activation of the heat shock transcription factor (HSF-1...
