Wave Energy Resource Characterization and Site Selection for Its Exploitation in the Ría de Pontevedra
Achieving the highest efficiency in the production of wave energy is based on two fundamental pillars. On the one hand, the selection of the best wave energy converter (WEC). On the other hand, the study of th...

Photogrammetric Survey of an Intertidal Area: A Case Study in NW Spain
For years, bathymetry technique has been employed to obtain georeferenced data of the depths of the water using an echo sounder on board. This led to some problems in shallow water because it requires a shallo...

Open AccessFraction of high-grade cervical intraepithelial lesions attributable to genotypes targeted by a nonavalent HPV vaccine in Galicia, Spain
Human papillomavirus (HPV) bivalent and quadrivalent vaccines have been widely implemented in worldwide organized immunization programs. A nonavalent HPV vaccine is now available in several countries. The obje...

Studying the Population of Radio-Loud Broad Absorption Line Quasars (BAL QSOs) from the Sloan Digital Sky Survey
Broad Absorption Lines (BALs) seem to be the most extreme manifestations of quasar (QSO) outflows. Two main scenarios have been proposed to explain the nature of BAL QSOs. They may be a physically distinct pop...

Use of Neural Networks for the Identification of New z > 3.6 QSOs from FIRST–SDSS DR5
We aim to obtain a complete sample of z ≥ 3. 6 radio QSOs from FIRST sources having star-like counterparts in the SDSS DR5 photometric survey (r AB ≤ 20. 2). The starting sample of FIRST–DR5 pairs includes 4,250 ...

WFD Indicators and Definition of the Ecological Status of Rivers
The Water Framework Directive (WFD) aims to solve the problems derived from the use of water, a limited natural resource, by extending the scope of protection to all water uses. The WDF defines the ecological ...

Evolution of the Space Density of Quasars from Z = 2 To Z = 4
From a new sample of optically-luminous radio-loud quasars (MAB (1450 Ǻ) < -26.9 and log10P1.4 GHz (W Hz−1) > 25.7) with 3.8 < z < 4.5, obtained from the cross-correlation of VLA FIRST and POSS-I APM, we derive a...

Limits on Dust Extinction in B3 QSOS
The broad range of optical–infrared colours of radio QSOs,1 < B-K < 6, has been cited as evidence for several mag of dust extinction (Webster et al.. If such large extinctions are typical, the implications for ou...

The Shape of the Blue/UV Continuum of B3-VLA Radio Quasars
We present some results based on optical photometry of an unbiased subsample of 64 sources, from a sample of radio quasars 80 per cent complete. The quasars (z=0.4-2.8) show approximately a similar spectral en...

X-ray Observations of Active Galactic Nuclei in the Cosmological Context
We review recent discoveries of obscured Active Galactic Nuclei at significant redshifts with X-ray observations. Most, if not all, the X-ray luminous galaxies found at faint X-ray fluxes could in fact be obsc...

Red Quasars: Not so Dusty
Webster et al (1995) claimed that up to 80% of QSOs may be obscured by dust. They inferred the presence of this dust from the remarkably broad range of B-K optical-infrared colours of a sample of flat-spectrum PK...

B-K Colours of Low-Luminosity Radio Quasars
It has recently been suggested (Webster et al. 1995), on the basis of the observed broad range of B — K colours of radio- selected QSOs, that a large fraction are heavily reddened by dust extinction in B, and th...

Optical Properties of B2 Radio Galaxies
We present a large program of CCD imaging of low-luminosity radio galaxies selected from the B2 survey of radio sources. We aim to study their optical properties: brightness profiles, isophotal distortions, mo...

The Proximity Effect on the Lyman α Forest Due to a Foreground QSO
We present the results of our study on three close pairs of QSOs. Our results are consistent with the existence of a proximity effect. due to the foreground QSO, but due to its weakness we can only reject the ...

GGD 17: A Herbig-Haro Jet Associated with the T Tauri Star Bretz 4?
We have obtained continuum and emission line CCD images of the suspected HH object GGD 17. The object is associated with the T Tauri star Bretz 4. The images reveal a chain of HH knots. We believe that GGD 17 ...

Near Infrared-IRAS Candidates for Molecular Outflows in Lynds Clouds
Near infrared observations of cold IRAS sources associated with Lynds dark clouds allowed the detection of 13 objects which, in some cases, could represent young embedded stars energizing molecular outflows.
