[EN] Playa Barca is a 370 m long beach located within the system of the Leeward beaches on the Jandía peninsula, Fuerteventura. This system of beaches represents one of the major sources of economic income to the island, both because of its natural landscape that attract a specific type of tourism, and because of its particular climate conditions that make these beaches ideal for practicing wind-water sports. Nevertheless, in the past decades, this area has suffered from a significant and worrying coastline retreat. In order to look for an explanation to this retreat, five topographic surveys were carried out in October 1999, February 2001, February 2002, February 2003 and February 2013 to track the beach behavior in the last 15 years. A total station Topcon GTS-303D was used for this purpose. Surveys were carried out during low spring tides, so that the outer limit was the furthest possible depending on wave conditions. The inner limit covered part of the dunes in the backshore. From these topographic data both coastline changes and the sedimentary balance have been obtained.

[ES] Alrededor de la Bahía de Cádiz, los depósitos marinos de la regresión del Plioceno superior, forman una orla más o menos continua que se extiende hasta las proximidades de Chipioja al N., hasta Chiclana al S., constituyendo la Sierra de San Cristóbal el límite más oriental de la misma. Una cantera situada a 1,5 km al NE. de Puerto Real (lat. 36' 32' 15", long. 2' 28' 40". H.M.T.N. 1 : 50.000 núm. 1062), ofrece un amplio corte donde es posible observar los tramos marinos y salobres regresivos, así como los depósitos cuaternarios, continentales, más antiguos observados en el litoral gaditano. Se realiza un estudio detallado de dicho corte, y se discute el problema del límite Plio-Pleistoceno en dicho sector.

The data of 46 adults with single-sided sensorineural deafness who were candidates for bone-anchored hearing aids (Baha) CROS (contralateral routing of signals) were analyzed. All candidates tested a Baha with a headband in their normal environment. Subsequently, 29 of the candidates chose a permanent Baha CROS fitting, and 17 declined, thus forming the two study groups. No significant difference regarding age, sex or duration of deafness was found between the two groups. Similarly, the transcranial attenuation was not significantly different between those who accepted and declined a Baha. Subjects with some residual hearing in their poorer ear tended to decline a Baha, but the effect was not statistically significant. For a subset of 28 subjects, the Bern Benefit in Single-Sided Deafness questionnaire was administered. The questionnaire consists of 10 visual analogue scales rating the subjectively perceived benefit of the Baha or any other CROS device in different situations. Scores were found to be significantly higher for speech understanding at some distance (p = 0.026), for speech understanding in noise (p = 0.037), for group conversations (p < 0.01), and for the overall benefit (p < 0.01) for those candidates who chose to use a Baha as a CROS device permanently.
