The extreme outburst of EX Lup in 2008: Optical spectra and light curve
EX Lup is the prototype of EXors, a class of pre-main sequence eruptive variables, exhibiting unpredictable brightenings lasting some months (Herbig, 1977; Herbig et al., 2001; Herbig, 2007). According to the current ...
Carbamodithioates in the synthesis of diaroyl sulfides; selectivity in the addition of diaroyl sulfides to acetylenic and ethylenic π.deficient compounds
Diaroyl sulfides were prepared in one-pot reaction from ethylenediamine and carbon disulfide, via reaction of in situ generated ethylene-bis- carbamodithioates with aroyl chlorides. The reaction of diaroyl sulfides with ...
Resonance problems with respect to the Fučík spectrum of the p-Laplacian
We solve resonance problems with respect to the Fučík spectrum of the p-Laplacian using variational methods.
RECENT OCCURRENCE OF THE SMALLTOOTH SAWFISH, PRISTIS PECTINATA (ELASMOBRANCHIOMORPHI: PRISTIDAE), IN FLORIDA BAY AND THE FLORIDA KEYS, WITH COMMENTS ON SAWFISH ECOLOGY
Encounters with the smalltooth sawfish, Pristis pectinata, in Florida Bay and the Florida Keys were documented by soliciting information from anyone who might have encountered them in these areas. Each person who had ...
Singular positone and semipositone boundary value problems of second order delay differential equations
In this paper we present some new existence results for singular positone and semipositone boundary value problems of second order delay differential equations. Throughout our nonlinearity may be singular in its dependent ...
System size and energy dependence of jet-induced hadron pair correlation shapes in Cu+Cu and Au+Au collisions at sNN=200 and 62.4 GeV
We present azimuthal angle correlations of intermediate transverse momentum (1-4GeV/c) hadrons from dijets in Cu+Cu and Au+Au collisions at sNN=62.4 and 200 GeV. The away-side dijet induced azimuthal correlation is broadened, ...
Study of resonance formation in the mass region 1400- 1500 MeV through the reaction γγ→K0 SK±π ∓
The K0 SK±π∓ final state in two-photon collisions is studied with the L3 detector at LEP at e+e- centre-of-mass energies from 183 to 209 GeV with an integrated luminosity of 664.6 pb-1. The η(1475) and f 1(1420) mesons are ...
Effects of vitamin E on lipid peroxidation in healthy persons
Context: Oxidative stress may play a role in the development or exacerbation of many common diseases. However, results of prospective controlled trials of the effects of antioxidants such as vitamin E are contradictory. ...
Oxidized derivatives of ω-3 fatty acids: Identification of IPF 3α-VI in human urine
Isoprostanes (iPs) are prostaglandin-like molecules derived from autoxidation of polyunsaturated fatty acids (PUFAs). Urinary iP levels have been used as indices of in vivo lipid peroxidation. Thus far, it has only been ...
