Na - O Anticorrelation And HB I . The Na - O anticorrelation in NGC 2808 ⋆

We derived atmospheric parameters and elemental abundances of Fe, O and Na for about 120 red giant stars in the Galactic globular cluster NGC 2808. Our results are based on the analysis of medium-high resolution (R=22000-24000) GIRAFFE spectra acquired with the FLAMES spectrograph at VLT-UT2 as a part of a project aimed at studying the Na-O anticorrelation as a function of physical parameters i...

W and Z Physics

The electroweak theory elegantly combines the electromagnetic and weak forces, explaining a wide range of interactions using a gauge theory with just three parameters. The theory predicted the W and Z weak gauge bosons before they were directly observed in 1983, and its detailed predictions of W and Z boson properties have been tested to such precision that they now serve as probes for new part...

[The role of gerontology in the diagnosis and treatment of cardiovascular diseases].

Niepodlegający wątpliwości fakt coraz częstszego korzystania przez osoby w zaawansowanej starości z wielu dziedzin medycyny prowokuje do rozważań, jak leczyć takich chorych. Czy standardy postępowania dla osób po 85. roku życia to te same standardy, którymi posługuje się filozofia medycyny opartej na faktach? Jak reagować na zupełnie nieplanowane przez nas efekty leczenia lub – co najtrudniejsz...

[(Z)-O-Methyl-N-propyl­thio­carbamato-κS](triphenyl­phosphine-κP)gold(I)

In the title compound, [Au(C(5)H(10)NOS)(C(18)H(15)P)], the Au(I) atom is linearly coordinated within an S,P-donor set with distortion from an ideal linear geometry [S-Au-P = 176.71 (6)°] due to an intra-molecular Au⋯O contact [2.943 (4) Å]. In the crystal structure, centrosymmetrically related mol-ecules associate via C-H⋯O inter-actions.
