Active Galaxies in the UV
Full text linkIn this article we present different aspects of AGN studies demonstrating the
importance of the UV spectral range. Most important diagnostic lines for
studying the general physical conditions as well as the metalicities in the
central broad line region in AGN are emitted in the UV. The UV/FUV continuum in
AGN excites not only the emission lines in the immediate surrounding but it is
responsible for the ionization of the intergalactic medium in the early stages
of the universe. Variability studies of the emission line profiles of AGN in
the UV give us information on the structure and kinematics of the immediate
surrounding of the central supermassive black hole as well as on its mass
itself.Comment: 29 pages, 13 figures, Ap&SS in pres

From its origins ill the Fertile Crescent, farming expanded throughout Europe, Asia and Africa, together with various domesticated plants and animals. Where, how and why agriculture originated is still debated. Progress has been made in Understanding plant domestication in the last few years. New insights were obtained mainly due to (I) the use of comprehensive germplasm collections covering the whole distribution area for each species; (II) the comparison of many wild and domesticated accessions for each species; (III) the identification of the wild progenitor in the wild gene pool and its comparison with domesticate descendants (IV) the use of molecular fingerprinting techniques at many loci and the access to new generation high-throughput sequencing technologies; (V) the identification and cloning of genes involved in domestication, and (VI) excavation campaigns. This chapter reviews the recent knowledge on wheat, barley and rye domestication in the Fertile Crescent and covers several issues concerning the molecular knowledge of the effects induced by domestication and breeding of these crops
