Aquest treball fa un estudi dels baixonets a Catalunya des de les perspectives organològica, funcional i del repertori. A partir de les informacions aportades pels instruments originals, pels tractats i per estudis especialitats, es defineixen una tipologia instrumental pròpiament hispànica, i unes funcions principalment relacionades amb la música vocal religiosa de mitjans del segle XVI a mitjans del segle XVIII. Posteriorment, es realitza un estudi de la música amb baixonet a la localitat de Canet de Mar. A partir del treball de camp al seu arxiu parroquial, es compilen vuit obres específiques per a baixonet, se'n transcriuen alguns manuscrits, i se'n defineixen els principals aspectes formals i funcionals. El cas de Canet de Mar es pot considerar com un exemple més o menys representatiu de la pràctica instrumental i del repertori específic del baixonet a Catalunya a finals del segle XVII i començaments del segle XVIII.

El dia 27 de febrer de 1998 va tenir lloc a la Universitat de Girona la jornada «El PEIN cinc anys després: balanç i perspectives», organitzada per la Càtedra de Geografia i Pensament Territorial (UdG) i la Societat Catalana d’Ordenació del Territori. L’objectiu era reflexionar sobre el Pla d’Espais d’Interès Natural cinc anys després de la seva entrada en vigor i valorar fins a quin punt s’havien acomplert les expectatives que havia despertat i com podia afrontar els nous reptes en la conservació del patrimoni natural

L’any 2001, la Càtedra de Geografia i Pensament Territorial de la Universitat de Girona va rebre l’encàrrec de l’Ajuntament de Figueres d’analitzar les característiques de l’espai no urbanitzat del municipi i voltants immediats, sobretot des de la seva perspectiva paisatgística i del medi natural. Aquest encàrrec s’emmarcava dins dels estudis previs a la revisió del Pla general d’ordenació urbana de Figueres. El resultat fou la confecció del document que porta per títol: “Estudi del medi natural i del paisatge geogràfic de Figueres”. Per mitjà d’aquesta comunicació, es volen oferir els resultats més rellevants als quals s’arribà llavors. Es farà un cop d’ull a les unitats de paisatge geogràfic del municipi de Figueres identificades en el treball, quines són les seves característiques, els seus potencials però també les seves amenaces. El document havia de ser una eina que ajudés a incorporar, adequadament, els valors que apleguen aquests paisatges i espais a l’ordenació futura del municipi. D’aquí que, al text, s’acabin proposant algunes línies d’actuació per a millorar-ne la seva gestió, sobretot des del punt de vista urbanístic

Por el fondo de un valle de la provincia de Girona mana un conjunto de surgencias cuyo caudal total anual se acercaa medio centenar de hectómetros cúbicos. Controlando no solo la cantidad de agua de salida sino también su calidad desde el punto de vista de su contenido en tritio y a partir de un modelo conceptual de mezcla uniforme de las aguas de recarga, ya com probado en otros sistemas, se acota la cadencia de participación en las surgencias de las distintas recargas anuales, as como el tiempo de renovación del volumen de agua del sistema hidrogeológico

A second set of UBVRI photometry results for nearby stars of Gliese's (1969) catalog and its supplements, including in this case some multiple systems, are presented. Most of the observations were carried out between July 1984 and December 1985 at Calar Alto with the 1.23-m Centro Astronomico Hispano-Aleman telescope and the 1.52-m Observatorio Astronomico Nacional telescope. The number of observations of program and standard stars for the six runs and the final results for 60 stars are presented.

Here we discuss two consecutive MERLIN observations of the X-ray binary LS I +61◦303. The first observation shows a double-sided jet extending up to about 200 AU on both sides of a central source. The jet shows a bent S-shaped struct ure similar to the one displayed by the well-known precessing jet of SS 433. The precession suggested in the first MERLIN image becomes evident in the second one, showing a one-sided bent jet significantly rotated with respect to the jet of the day before. We conclude that the derived precession of the relativistic (β=0.6) jet explains puzzling previous VLBI results. Moreover , the fact that the precession is fast could be the explanation of the never understood short term (days) variability of the associated gamma-ray source 2CG 135 + 01 / 3EG J0241 + 6103.

The possible associations between the microquasars LS 5039 and LS I +61 303 and the EGRET sources 3EG J1824-1514 and 3EG J0241+6103 suggest that microquasars could also be sources of high-energy gamma-rays. In this work, we present a detailed numerical inverse Compton (IC) model, based on a microquasar scenario, that reproduces the high-energy gamma-ray spectra and variability observed by EGRET for the mentioned sources. Our model considers a population of relativistic electrons entrained in a cylindrical inhomogeneous jet that interact through IC scattering with both the radiation and the magnetic fields.

In order to complete the photometric data of the Gliese (1969) 'Catalog of Nearby Stars', and in addition use these data for the Hipparcos space astrometry mission, program stars have been selected from the catalog and its supplements on the basis of their having an incomplete set of UBVRI photometric data of magnitude lower than 13. The program developed rejects determinations of any magnitude or color index having a residual greater than 2(sigma-prime), where sigma-prime is the standard deviation for the determinations of unit weight.

UBVRI photoelectric photometry is presented for 269 late spectral type, high proper motion stars belonging to the 'Lowell Proper Motion Survey' and included in the present version of the Hipparcos Input Catalogue. The observations and data reduction are described. The external errors obtained by comparison of the results with those obtained in other studies are presented.

As indicated by Grenon (1989), the data of the present series of reports on the UBVRI photometry of late-type stars in the Hipparcos Input Catalog are to be employed in computations of Hipparcos observing time, as well as in evaluating the observability of faint stars by the satellite. Attention is here given to late type stars in the V = 8-12 range, including distant red giants in the Galactic plane (Hipparcos proposal 189), as well as high proper motion stars included in the G, LTT, LP, and MCC catalogs.

We describe the motivation, design, and implementation of the CORNISH survey, an arcsecondresolution radio continuum survey of the inner galactic plane at 5 GHz using the Very Large Array (VLA). It is a blind survey coordinated with the northern SpitzerGLIMPSE I region covering 10° imilar resolution. We discuss in detail the strategy that we employed to control the shape of the synthesised beam across this survey, which covers a wide range of fairly low declinations. Two snapshots separated by 4 h kept the beam elongation to less that 1.5 over 75% of the survey area and less than 2 over 98% of the survey. The prime scientific motivation is to provide an unbiased survey for ultra-compact H II regions to study this key phase in massive star formation. A sensitivity around 2 mJy will allow the automatic distinction between radio-loud and radio-quiet midIR sources found in the Spitzersurveys. This survey has many legacy applications beyond star formation, including evolved stars, active stars and binaries, and extragalactic sources. The CORNISH survey for compact ionized sources complements other Galactic plane surveys that target diffuse and nonthermal sources, as well as atomic and molecular phases to build up a complete picture of the interstellar medium in the Galaxy.
