Radiative losses have been determined by using the Arcetri Code line emissivities for each element calculated adopting a plasma electron density of 10 10 cm -3 . Each emissivity line is structured using the following format: An example from the Mg file (Phot cm 3 s -1 ) is given below: . ...

... We computed the permanently shadowed areas and temperatures inside the craters for the variation of the position of the lunar pole of rotation with respect to the ecliptic pole with a period of 18.6 years. ... According to our results, the total permanently shadowed area in the polar craters of the Moon is equal to 50428.7 km2, or 0.13% of the total area of the lunar surface [3]. ... The area of permanently shaded part of a crater makes 59 % from all area of a crater [3]. ...

... Because the DMR instrument is differential and every pixel is multiply sampled, sky maps are produced by solving a coupled system of linear equations (the normal equations) to minimize a chi-squared. ... This is reflected in the algebraic form of the normal equations matrix, so that, if one were to diagonalize the matrix, one would find a single eigenvector whose eigenvalue was identically zero, and the associated eigenvector, viewed as a sky map, would have a constant value. ...

... The collecting area is increased by nesting concentric mirror pairs, all having the same focal length. ... Figure shows the largest optical element being ground at HDOS. ... X-ray testing demonstrated that the CXO mirrors are indeed the largest high-resolution X-ray optics ever made; the nominal effective area (based on the ground calibrations) is shown as a function of energy in the left panel of Figure , along with those of their Einstein and ROSAT predecessors. ...

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. ...
