For example the firms in the systems of transmission and distribution are far more numerous than in France. The market is more competitive. The main society of electricity transmission is owned by the Canadian Brookfield Asset Management Inc. This situation prevents from generating economies of scale since there are a lot of little firms. The National Energy Commission is responsible for regulating prices and for deciding energy policies. Reforms in the 80’s have taken politics away from the decisions, by replacing regulation by a competitive market. In 2010, system will become a tender system.

The Chilean primary energy consumption balance is: 38% from petroleum products, 21% natural gas and 18% hydroelectric. On the other side, Chile is importing 95% of the oil and 70% of the natural gas it consumes. The Mining industry is the major electricity consumer.

    Indigenous Environmental Rights, Participation and Lithium Mining in Argentina and Bolivia: A Socio-Legal Analysis Helle Abelvik-Lawson A thesis submitted for the degree of PhD School of Law and Human Rights Centre and Interdisciplinary Studies Centre University of Essex Date of submission: May 2019 For my family, on Earth and in Heaven. i ACKNOWLEDGEMENTS First and foremost, I must thank my incredible husband-to-be Dauji Thomas, truly one of the world’s most amazing individuals, and without whom absolutely none of this would have been possible. Thank you for being there for me, and your understanding, through the hard times and the good. I am in fact wholly indebted to all my family, particularly my amazing Mama for showing me how to keep going even when the going is tough, and of course my stepdad Dean. Thanks also to Guy for giving me a wonderful place to study in the stunning Essex countryside. To my brother Frase, and Dix and Cos: I am so glad to have you all in my life. I am deeply grateful for the support of my dedicated, and encouraging and insightful supervisors, Professor Karen Hulme and Dr Jane Hindley, who went beyond the call of duty to help me achieve my aims. At Essex and elsewhere, I am incredibly fortunate to count a number of academics and experts in the field as mentors and friends, who continually pique my curiosities and inspire me to continue working in human rights. Dr Damien Short, Professor Colin Samson, Dr Corinne Lennox, Dr Julian Burger – thank you for showing me how it’s done.

El río Loa nace en la falda norte del Vn. Mi­ ño~ en los Ojos del Hiño, casi en los límites entre la la y IIa Regio­ nes de Chile, en 21Q15' L.S. y 70Q L.O~ Su longitud total se acerca a 440 km. A pesar de su extensa hoya, los recursos h!dricos provienen de la cuenca alta que comprende alrededor del 20% de la su~ perficie total. Con curso aproximadamente norte-sur~ el Loa reco­ rre casi 150 km en un profundo cañón de altura variable, desde su nací miento hasta el oasis de Chiu ~hiu, pueblo que se levanta en su margen izquierda. En este trayecto recibe sus dos tributarios más importantes que le caen del este: el río San Pedro o Inacaliri y el río Salado. En Chiu Chiu dobla su curso sensiblemente hacia el oeste para alcanzar en un recorrido de 115 km el punto denominado Chacance. En él se le reúne por la derecha el río San Salvador. En Chacance,el Loa toma franca di= recci6n sur-norte hasta fertilizar el oasis de Quillagua, despu~s de una trayectoria de 80 km.

  • Convergent Margin Magmatism in the Central Andes and Its Near Antipodes in Western Indonesia: Spatiotemporal and Geochemical Considerations
    AN ABSTRACT OF THE DISSERTATION OF Morgan J. Salisbury for the degree of Doctor of Philosophy in Geology presented on June 3, 2011. Title: Convergent Margin Magmatism in the Central Andes and its Near Antipodes in Western Indonesia: Spatiotemporal and Geochemical Considerations Abstract approved: ________________________________________________________________________ Adam J.R. Kent This dissertation combines volcanological research of three convergent continental margins. Chapters 1 and 5 are general introductions and conclusions, respectively. Chapter 2 examines the spatiotemporal development of the Altiplano-Puna volcanic complex in the Lípez region of southwest Bolivia, a locus of a major Neogene ignimbrite flare- up, yet the least studied portion of the Altiplano-Puna volcanic complex of the Central Andes. New mapping and laser-fusion 40Ar/39Ar dating of sanidine and biotite from 56 locations, coupled with paleomagnetic data, refine the timing and volumes of ignimbrite emplacement in Bolivia and northern Chile to reveal that monotonous intermediate volcanism was prodigious and episodic throughout the complex. 40Ar/39Ar age determinations of 13 ignimbrites from northern Chile previously dated by the K-Ar method improve the overall temporal resolution of Altiplano-Puna volcanic complex development. Together with new and updated volume estimates, the new age determinations demonstrate a distinct onset of Altiplano-Puna volcanic complex ignimbrite volcanism with modest output rates beginning ~11 Ma, an episodic middle phase with the highest eruption rates between 8 and 3 Ma, followed by a general decline in volcanic output. The cyclic nature of individual caldera complexes and the spatiotemporal pattern of the volcanic field as a whole are consistent with both incremental construction of plutons as well as a composite Cordilleran batholith.

PUTNAM'S SONS MDCCCCXII F A^>in.r4> PREFACE IT is not without great diffidence that I have ven- tured to compile the following chapters on the archaeology of South America. The subject is one of great magnitude, and the literature dealing with it is vast. Besides this, there exist so many gaps in our knowledge, gaps which can only be filled by years of patient excavation, that the formation of theories is still a precarious task. At the same time it is useful to pass in review the work which has already been completed, with the object both of pointing out the missing links in the chain of evidence, and of stimulat- ing further research by calling attention to the results already achieved.
