Development of the instrumentation of the botafoc breakwater nº 8 caisson

Balearic Port Authority has developed an instrumentation system for the #8 caisson of the Botafoc breakwater that integrates 12 pressure sensors located at three surfaces, two in contact with the sea water and another with the bottom. This design was completed with an inertial system that measures the angular velocities and the accelerations over the three Cartesian axes. Consequently, the system measures actions (pressures) and reactions (movements and accelerations) experimented by the caisson, due to sea waves and/or other service loads. R+D department of the Port Authority and Polytechnic University of Madrid are working on two directions, the development of new theories on vertical breakwater design that go beyond Goda and Sainflou, and on the creation of a real-time critical structure alarm system, based on the instrumentation installed. This alarm system has two main parts: the instrumentation itself that collects data and processes it on real-time (the data processing compares the pressure law suffered by the caisson in every step process with the design critical state of the caisson, in this case the Goda pressure law for a 6.5 m wave), giving a security coefficient that points out the risk level on real-time; and the alarm system consisting of a monitoring panel located in the Port Control Center that shows the risk level and advises in case of an incidental evacuation of this critical portuary installation

A new species of lizard endemic to sierra de fiambalá, northwestern argentina (Iguania: Liolaemidae: Phymaturus). integrated taxonomy using morphology and DNA sequences: Reporting variation within the antofagastensis lineage

The northernmost distributed group of lizards belonging to Phymaturus occurs in rocky outcrops of the Puna region between 3600-4200 m in Argentina. In a recent phylogenetic study based on morphological and genetic information, the monophyly of this small lineage was corroborated. This group is formed by Phymaturus antofagastensis, P. laurenti, P. denotatus, P. mallimaccii and a population of uncertain taxonomic status until the present study. After obtaining new samples and observations, we described a new species belonging to this lineage that is known only from Sierra de Fiambalá, being the species of Phymaturus living at the highest elevation ever recorded (4500 m). Males have a homogeneous yellow dorsum and lack melanic coloration over their heads, a phenomenon found in males of most species of the palluma group. We provide a detailed diagnosis, including characters from the squamation, coloration and significant differences found among continuous characters (ANOVA). Furthermore, we present genetic distances among members of the mallimaccii subclade based on sequences of the cytb marker. We provide color photos showing pattern variation of males and females. We reanalyze the phylogenetic relationships within the entire palluma group and update info on all members of the antofagastensis lineage based on new samples and make a better supported hypothesis. We also evaluate the phylogenetic position of the new taxon.Fil: Lobo Gaviola, Fernando Jose. Consejo Nacional de Investigaciones Científicas y Técnicas.

Hydrogeological characterization of the Salinas-Los Hoyos evaporitic karst (Malaga province, S Spain) using topographic, hydrodynamic, hydrochemical and isotopic methods

The Salinas-Los Hoyos karst system is a geological diapiric structure formed by materials of diverse nature (clays, sandstones, evaporites, volcanic rocks, dolostones, etc.) placed between Malaga and Granada provinces (S Spain). The abundance of evaporite rocks (gypsum, anhydrite and halite) and their high solubility contribute to the development of exokarstic features (dolines, uvalas, sinkholes). Grande and Chica lakes are dolines located in the western border of the diapir that are intersected by the piezometric level. Close to the first wetland is the Aguileras spring, which is the main discharge point of the west sector of the system. To assess the wetland-spring relation and the general functioning of the system, the geomorphologic framework has been analyzed and hydrogeological controls have been performed, consisting in limnimetric and discharge logging and in situ measurements of physico-chemical parameters (EC and water temperature). Furthermore, spring, wetland and rain water samples have been taken for subsequent chemical and isotopic analysis. Preliminary results show that wetland water level and spring discharge follow a similar trend, consistently with the inertia of the system. However, their hydrochemical evolution and isotopic values differ, thus wetland groundwater interaction has not been fully determined. Nevertheless, present research suggests that the hydrogeological connection would be more likely during wet periods, when the water table is at higher altitude.Key words: Evaporitic (karst) aquifer, Hydrological and hydrogeological behaviours, Natural responses, South Spain, Wetlands

Fotosensibilización primaria por consumo de Ammi majus en bovinos: primer reporte en Argentina

Se describe un brote de fotosensibilización primaria en bovinos causado por el consumo de Ammi majus. Los animales manifestaron fotofobia, epífora, opacidad corneal bilateral y dermatitis en pezones, vulva y morro. Se descartó un origen secundario por daño hepático y se confirmó el diagnóstico por consumo voluntario de A. majusPrimary photosensitization due to the consumption of Ammi majus was diagnosed in a bovine herd. Clinical signs included photophobia, epiphora, bilateral corneal opacity and dermatitis in udder, vulva and muzzle. A secondary photosensitization was ruled out and consumption of A. majus was diagnosed.EEA BalcarceFil: Dorsch, Matías A. Instituto Nacional de Tecnología Agropecuaria (INTA).
