DFT ispitivanje antioksidativne aktivnosti alizarina Red S
No full textDensity functional theory calculations were performed to evaluate the
antioxidant activity of alizarin red S molecule. The conformational behavior of molecule
were analysed at the M06-2X/6-311++G(d,p) method. The most stable conformer of
alizarin red S has two IHBs. The expected antioxidant activity of alizarin red S was
justified from ionization potential (IPs) and homolytic O-H bond dissociation enthalpy
(BDEs) values. Heterolytic O-H bond cleavages (proton dissociation enthalpies, PDEs)
were also computed. Calculated IP, BDE, and PA values suggested that one-step H atom
transfer (HAT), rather than SPLET or SET-PT, would be the most favored mechanism for
explaining the antioxidant activity of alizarin red S in gas phase. In aqueous solution all of
three mechanisms were competitive.Upotrebom DFT metode vršena su izračunavanja u cilju određivanja
antioksidativne aktivnosti alizarina red S. Konformaciona priroda molekula analizirana
ispitana je primenom M06-2X/6-311++G(d,p) metoda. Najstabilniji konformer alizarina
red S ima dve unutrašnje vodonične veze. Očekivana antioksidativna aktivnost alizarina
red S određena je izračunavanjem vrednosti jonizacionih potencijala (IP) i i vrednosti
entalpija homolitičkog raskidanja O-H veza (BDE). Vrednosti entalpije heterolitičkog
raskidanja O-H veza (entalpije disocijacije protona, PDE), su takođe izračunate.
Izračunate IP, BDE i PA vrednosti ukazuju na to da je jednostepeni transfer H-atoma
(HAT), pre nego SPLET ili SET-PT mehanizam, favorizovan u pogledu antioksidativne
aktivnosti alizarina red S u gasnoj fazi. U vodenom rastvoru, sva tri mehanizma su

Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
The astrochemical observatory: Computational and theoretical focus on molecular chirality changing torsions around O – O and S – S bonds
No full textThe observation of hydrogen peroxide in the interstellar medium represents a remarkable discovery for the astrochemistry community. The prototypical role that this molecule, arguably the simplest chiral molecule, plays in the evolution of life in biospheres, is related to the chirality change transitions associated with the torsional motions around the O - O and the S - S bonds. In this paper, we present an overview on the state-of-art of possible experiments to demonstrate chiral effects discrimination and computational tools applied to peroxides and persulfides

Search for new phenomena in final states with large jet multiplicities and missing transverse momentum at s√=8 TeV proton-proton collisions using the ATLAS experiment
No full textA search is presented for new particles decaying to large numbers (7 or more) of jets, with missing transverse momentum and no isolated electrons or muons. This analysis uses 20.3 fb−1 of pp collision data at s√=8 TeV collected by the ATLAS experiment at the Large Hadron Collider. The sensitivity of the search is enhanced by considering the number of b-tagged jets and the scalar sum of masses of large-radius jets in an event. No evidence is found for physics beyond the Standard Model. The results are interpreted in the context of various simplified supersymmetry-inspired models where gluinos are pair produced, as well as an mSUGRA/CMSSM model
