A. Singh Institute of Mathematical Sciences, C.I.T. Chennai, India anupamk18@gmail.com Real elements in algebraic groups Let G be an algebraic group defined over a field k . ... Let G be a connected semisimple algebraic group of adjoint type defined over a perfect field k . ... It follows that if G is connected semisimple of adjoint type, with -1 in its Weyl group, then every semisimple element in G(k ) is strongly real in G(k ). This also shows that any regular element in such a group is real. ...

FEATURES OF THE HYDROGEN DISTRIBUTION AROUND LUNAR CRATERS PROCLUS AND KEPLER. ... In result of analysis of the data Lawrence and Feldman constructed the hydrogen distribution on the lunar surface [1]. ... However, the authors shown, that EN flux data features may be explained by other element abundance in the lunar soils, namely: Si, Ca, Gadolinium (Gd), Samarium (Sm) and Fe. ... Using of the Feldman's interpretation of the Lunar Prospector data [8], we constructed hydrogen distribution map (Fig.1). ...

It is possible to piece together the processes that have shaped the observed characteristics of a galaxy by studying its stars in detail. The Large Magellanic Cloud (LMC) is an excellent candidate for this type of study because of its favourable viewing angle and ongoing star formation. I present the results of high-resolution VLT/FLAMES observations of ~80 red giant stars around star cluster NGC 1846, located in the disc of the LMC. ...
