La Geologia Estructural s'ocupa de la deformació de les roques, tant des del punt de vista deis mecanismes que la possibiliten i de les condicions en que aquesta deformació es produeix, com des de la prespectiva de les geometries resultants. La Tectonica s'ocupa de la deformació de I'escorc;a terrestre fins i tot de la litosfera; a més a més d'estudiar les estructures i la seva evolució en els temps, també s'ocupa deis processos que causen la deformació o que resulten d'ella. No hi ha, com es veu, una frontera clara entre Tectonia i Geologia Estructural. Potsser podriem considerar que la frontera queda determinada per la mida de I'objecte estudiat, aixf mentre la Tectonica s'ocupa de les estructures a escala de tota una serralada o d'una placa, la Geologia Estructural estudia estructures individuals o sistemes (ex. sistema d'encavalcaments). Potser una altra frontera es pot delinear en funció de les metodologies utilitzades, i en aquest cas la Tectonica és clarament més complexa i multidisciplinar ja que necessita del suport de la Geoffsica i la Geoqufmica. Ambdues disciplines varen neixer conjuntament. En els inicis, la Tectonica era potsser una manera parcial o especial d'entendre la Geologia Regional (aquesta darrera s'ocupa de I'estudi dé la interrelació de tots els aspectes geologics involucrats en una regió determinada). Durant aquests temps inicials la Geologia Estructural estava focalitzada en I'estructura de les serralades de muntanyes. Aixf el treball d'Argand (1924) que és un tfpic treball de Geologia Regional deis Alps, és un excel.lent exemple de Geologia Estructural on es descriuen amb detall les estructures espectaculars que constitueixen aquesta serralada. Pero al mateix temps, a I'englobar un erogen sencer i qüestionar-se pels processos que I'han originat, esdevé també un treball de Tectonica clarament avantguardista en el seu temps. 10 Bo/l. Soco Hist. Nat. Balears, 35 (1992) Més endavant, i amb la incorporaci6 del treball a petita escala i amb la introducci6 de models analogics, la Geologia Estructural ha evolucionat cap a dues branques diferents que s6n la deformaci6 fragil i la deformaci6 dúctil. Anderson (1963) va proposar un model conceptual de falles en el que hi ha una correspondencia unfvoca entre la geometria del sistema de falles i la

  • The Brown Algae Cystoseira Baccata Extract As a Friendly Corrosion Inhibitor on Carbon Steel in Acidic Media
    Research Article The brown algae Cystoseira Baccata extract as a friendly corrosion inhibitor on carbon steel in acidic media T. Benabbouha1 · R. Nmila2 · M. Siniti1 · K. Chefra3 · H. El Attari3 · H. Rchid2 Received: 18 January 2020 / Accepted: 11 March 2020 / Published online: 16 March 2020 © Springer Nature Switzerland AG 2020 Abstract The inhibition properties of the isopropanol extract of brown seaweed Cystoseira baccata (CBE), against corrosion of carbon steel in HCl 1M medium, was evaluated using the weight-loss method and electrochemical measurements. It was shown that the extract exhibit excellent performance as inhibitors and the inhibition efciency increased with the concentration. The maximal value of inhibition efciency is 86.5% obtained by the Tafel method at 700 mg/l at 298 K. The polarization curves indicate that the CBE acts as a mixed-type inhibitor. The results obtained by electrochemical impedance spectroscopy shows that the inhibitory action of this extract is based on the increase in the charge transfer resistance and the decrease in the double layer capacity. The temperature infuence studied in the temperature range 298–328 K by weight-loss method shows that the inhibition efciency decreases with increasing temperature for all concentrations of CBE. The adsorption and activation parameters allow us to suggest the physical adsorption of this inhibitor on the metal. The adsorption of the extract on the carbon steel follows Langmuir adsorption isotherm. Keywords Corrosion inhibitor · Carbon steel · Acid media · Seaweed · Cystoseira baccata · Extract 1 Introduction Since 1930, plant and algae extract has been used as a corrosion inhibitor. Studies on natural products extract as Corrosion inhibitors are chemical compounds added at a corrosion inhibitor has become more extensive [10–17].

    Field Studtes 5 (1979) 1-44 A FIELD KEY TO THE BRITISH BROWN SEAMJEEDS (PHAEOPHYTA) By SUE HISCQCK Field Studies Council Oil Pollution Research Unit, Orielton Field Centre, Pembuoke, Dyfed INTRODUCTION The larger, or macroscopic marine ALGAE (seaweeds)are mainly found in three of the algal classes : CHLOROPHYTA-Green algae, usually rather delicate plants, grass-green in colour. PHAEOPHYTA-Brown algae (the group covered by this key) which are either olive-green in colour or any shade of brown between golden to very dark. RHO1)OPHYTA-Red algae which exhibit a wide range of colours from red or pink to a dark purplish-brown, almost black. They often bleach to a light brown or yellow in bright sunlight and may then lbeconle difficult to separate from brown algae. The base, shaded by the rest of tlhe plant, often remains dark and plants with light upper parts and dark bases are probably red algae. Gigartina Laurencia Laurencia Chondrus Porphyra stellata pinnatifida hybrida crispus umbilicalis FIG. 1 Some littoral species of red algae that are commonly confused with brown algae. Microscopic individuals of blue-green alga~e(CYANIOPHYTA) are often present in large numbers and may appear as small black blobs or coloured slimes on seashores. The main parts of a brown seaweed are illustrated in Fig. 2. The shape (or absence) of the holdfast is important for the identification of some species. In others it is the shape and size of the receptacles (reproductive structures) and/or air bladders that must be noted. Air bladders are sometimes confused with receptacles, but bladders are generally smooth outside, hollow inside, and have no other visible structures.

Dr. Ignacio Bárbara Criado A mis dos ángeles de la guarda. “Piano piano si va lontano.” Agradecimientos A mi director Ignacio, por introducirme en este fascinante mundo de las algas y darme la oportunidad de realizar el doctorado. Gracias por tu infinita paciencia conmigo, por enseñarme y guiarme, por todo tu esfuerzo y dedicación, por ser exigente y comprensivo a partes iguales. Gracias no sólo por lo académico, sino por todos los buenos momentos vividos durante esta tesis, por recorrernos media Galicia buceando, por los amaneceres en el mar, por tener que acabar remando, por los intentos fallidos de tirarme al agua, por las sesiones eternas en el laboratorio rezando el Ángelus. Reconozco que tenías razón y ahora echo de menos todo aquello.
