    The main goal of this thesis is to study the interrelation of powerful radio sources with their hosts. The objects of study are GPS and CSS sources. Due to their small size, GPS/CSS sources are excellent probes of this relation. Furthermore, their young age allows us to compare them to the larger, old radio sources and establish a time-line evolution of this relation. This thesis combines imaging and spectroscopy of GPS/CSS sources at different wavelengths, and all our studies lead to the same conclusion: the presence and expansion of powerful radio sources clearly affect the properties and evolution of their hosts. All chapters of the thesis find evidence of strong interaction between the host and the radio source. Furthermore, the radio source and host can significantly affect each others evolution. However, this influence takes place in different ways. The influence that the host has on the radio source is somehow indirect. However it can completely change its destiny: depending of the contents, distribution and density of the gas, the radio source will die early, expand and grow into the large FR sources, or remain confined inside its host. In contrast, the influence of the radio source on its host seems to be more direct and takes place during its expansion through the host: the radio source will affect the kinematics and ionization of the emission line gas, and may change the star formation history of the host.Comment: Thesis dissertation.

    [email protected] este artículo el autor trata de señalar que la construcción de i{na más subjuntivo con valor de imperativo es anterior a la koiné. Asimismo trata de explicar su origen y sus fases a partir de un proceso de gramaticalización constatable, por ejemplo, en la lengua de Sófocles, Eurípides y Jenofonte.In this paper the author tries to point out that i{na with subjunctive as imperative is previous to koiné. Likewise he tries to explain its origin and phases starting from a grammaticalization process that is noticeable in the language of Sophocles, Euripides and Xenophon

    Aproximación a la lengua de los tratados hipocráticos De fistulis y De haemorrhoidibus

    A partir de una aproximación previa en un trabajo anterior a propósito de aspectos fonéticos y morfológicos en dos tratados quirúrgicos del Corpus Hippocraticum, De fistulis y De haemorrhoidibus, en el presente artículo se quiere continuar esta labor en el terreno de la sintaxis y el vocabulario, con vistas a poner de relieve algunos rasgos de griego helenístico que, claramente, aparecen en estos tratados. Todo ello refuerza la opinión de que estos tratados son obras de pleno siglo IV a. C., De haemorrhoidibus probablemente de mediados de siglo y De fistulis quizá algo anterior.From a previous approach about phonetic and morphological features in the Hippocratic treatrises De fistulis and De haemorrhoidibus, both among the surgical treatises in Corpus Hippocraticum, the author tries now to extend his research to vocabulary and syntax, in order to reinforce some Hellenistic feautures that clearly appear in these treatises. All of them prove our opinion that these treatises are clearly 4th Century compositions, De haemorrhoidibus probably towards the middle of the Century, De fistulis perhaps a little earlier

    Studying the spectral properties of Active Galactic Nuclei in the JWST era

    The James Webb Space Telescope (JWST), due to launch in 2014, shall provide an unprecedented wealth of information in the near and mid-infrared wavelengths, thanks to its high-sensitivity instruments and its 6.5 m primary mirror, the largest ever launched into space. NIRSpec and MIRI, the two spectrographs onboard JWST, will play a key role in the study of the spectral features of Active Galactic Nuclei in the 0.6-28 micron wavelength range. This talk aims at presenting an overview of the possibilities provided by these two instruments, in order to prepare the astronomical community for the JWST era.Comment: 8 pages, 1 figure, accepted for publication in New Astronomy Reviews (proceedings of 7th Serbian Conference on Spectral Line Shapes in Astrophysics
