Niagara-Welland Power Company Limited fonds, 1833, 1852, 1904-1906, 1909, n.d.

The Welland Power and Supply Canal Company Limited, established in 1893 and incorporated in 1894 with a capital stock of $500,000. The aim of the company was to harness the natural water supply of the Niagara and Welland Rivers. In 1898 the Canadian Electrical News published a report by Henry Symons, QC outlining the main project of the company. This project involves the construction of a canal from the Welland River to the brow of the mountain at Thorold, a distance of 8 miles; the construction at Thorold of a power house, and from Thorold to Lake Ontario, a raceway by which to carry water into the lake. The estimate for the machinery to generate 100,000 horse power is £125,000; for transmission line to Toronto at a voltage of 10,000….The total estimate therefore amounts to £2,452,162, or roughly speaking, $12,000,000. Source: Canadian Electrical News, August 1898, p. 172. In 1899 the company officers petitioned the federal government desiring a name change to the Niagara-Welland Power Company Limited. Officers of the company were Harry Symons, President; Charles A. Hesson, Vice-President; and M.R. O’Loughlin, James B. Sheehan, James S. Haydon, Frederick K. Foster, directors; John S. Campbell, secretary-treasurer. The company’s head offices were located in St. Catharines, with a New York (City) office on Broad Street. In 1905 and 1909 the company petitioned the federal government for additional time to construct its works, which was granted. The company had until May 16, 1915 to complete construction. John S. Campbell (1860-1950) was a graduate of the University of Toronto and Osgoode Hall. During his university years John began his military career first in "K" Company, Queens Own rifles and then later as Commanding Officer of the 19th Lincoln Regiment, from 1906 to 1910. Upon his return to St. Catharines John Campbell served as secretary in the St. Catharines Garrison Club, a social club for military men begun in 1899. After being called to the Bar, he became a partner in the firm of Campbell and McCarron and was appointed to the bench in 1916, serving until retirement in 1934. Judge Campbell served as an alderman for several terms and was the mayor of St. Catharines in 1908 and 1909. He also served as the first chairman of the St. Catharines Public Utilities in 1914. John S. Campbell was married to Elizabeth Oille, daughter of Jerome B. and Charlotte (St. John) Oille. The family home "Cruachan" was located at 32 Church St.

L'autre Basque

Le nationalisme basque est apparu voilà maintenant deux siècles, cependant, il ne connait un retentissement mondial que depuis environ cinquante ans avec la création de l’ETA (Euskadi Ta Askatasuna, Pays basque Et Liberté). Fondée pour combattre le régime franquiste, cette organisation est aujourd’hui considérée comme un groupe terroriste par l’ensemble de la communauté internationale. L’organisation va être, toutefois, à la base d’une prise de conscience nationale basque sur la question de l’appartenance à un même peuple et, aujourd’hui, la lutte pour l’autodétermination du Pays basque fait écho tant sur le territoire espagnol que français. Ce mouvement nationaliste, bien qu’indissociable entre le sud et le nord, prendra tout de même des modes d’expression différents même si le nationalisme basque restera toujours rattachée à une violence politique. Le présent terrain de recherche a alors permis de récolter les « perceptions subjectives » de la population basque sur cette violence politique et ainsi, de dégager une violence de la part des Etats espagnol et français. Cette violence d’Etat est principalement caractérisée par une violence symbolique mais elle ira parfois jusqu’à une violence physique. Ainsi, bien plus que les contextes historiques et institutionnels distincts des Etats espagnol et français, c’est la violence disparate des ces deux Etats qui est le facteur de distinction de la violence nationaliste constatée sur le territoire français et espagnol.

Erneuerbare Energien im Verbund mit Hochleistungs-Bleiakkumulatoren zur Bereitstellung von Spitzenleistung - am Beispiel von Windkraftwerken im 20 kV-Versorgungsnetz der CEGEDEL / Luxemburg -

Die wachsende Weltbevölkerung bedingt einen höheren Energiebedarf, dies jedoch unter der Beachtung der nachhaltigen Entwicklung. Die derzeitige zentrale Versorgung mit elektrischer Energie wird durch wenige Erzeugungsanlagen auf der Basis von fossilen Primärenergieträgern und Kernenergie bestimmt, die die räumlich verteilten Verbraucher zuverlässig und wirtschaftlich über ein strukturiertes Versorgungssystem beliefert. In den Elektrizitätsversorgungsnetzen sind keine nennenswerten Speicherkapazitäten vorhanden, deshalb muss die von den Verbrauchern angeforderte Energie resp. Leistung jederzeit von den Kraftwerken gedeckt werden. Bedingt durch die Liberalisierung der Energiemärkte und die geforderte Verringerung der Energieabhängigkeit Luxemburgs, unterliegt die Versorgung einem Wandel hin zu mehr Energieeffizienz und erhöhter Nutzung der dargebotsabhängigen Energiequellen. Die Speicherung der aus der Windkraft erzeugten elektrischen Energie, wird in den Hochleistungs-Bleiakkumulatoren, errichtet im ländlichen Raum in der Nähe der Windkraftwerke, eingespeichert. Die zeitversetzte Einspeisung dieser gespeicherten elektrischen Energie in Form von veredelter elektrischer Leistung während den Lastspitzen in das 20 kV-Versorgungsnetz der CEGEDEL stellt die Innovation in der luxemburgischen Elektrizitätsversorgung dar. Die Betrachtungen beschränken sich somit auf die regionale, relativ kleinräumige Einbindung der Windkraft in die elektrische Energieversorgung des Großherzogtums Luxemburg. Die Integration der Windkraft im Regionalbereich wird in den Vordergrund der Untersuchung gerückt. Überregionale Ausgleichseffekte durch Hochspannungsleitungen der 230/400 kV-Systeme werden außer Acht gelassen. Durch die verbrauchernahe Bereitstellung von elektrischer Spitzenleistung vermindern sich ebenfalls die Übertragungskosten aus den entfernten Spitzenlastkraftwerken, der Ausbau von Kraftwerkskapazitäten kann in die Zukunft verschoben werden. Die Emission von Treibhausgasen in thermischen Kraftwerken wird zum Teil reduziert. Die Berechnungen der Wirtschaftlichkeit von Hybridanlagen, zusammengesetzt aus den Windkraftwerken und den Hochleistungs-Bleiakkumulatoren bringen weitere Informationen zum Einsatz dieser dezentralen Speichern, als Partner der nachhaltigen Energieversorgung im ländlichen Raum. Die untersuchte Einspeisung von erneuerbarer Spitzenleistung lässt sich auch in die Entwicklungsländer übertragen, welche nicht über zentrale Kraftwerkskapazitäten und Verteilungsnetze verfügen.

Competitividad internacional urbana. Casos: Madrid, Dublín y Copenhague

La asignatura de Competitividad Internacional Urbana (ciu) del programa de Gestión y Desarrollo Urbanos (gdu) de la Universidad del Rosario ha sido desde 2009, cuando asumí su dirección y orientación, un reto permanente de aprendizajes tan estimulantes y variados cuantas ciudades y atributos hay por descubrir en el inmenso mundo de lo urbano-rural-regional. Si bien la competitividad es un asunto urbano-regional antes que nacional, la mayor parte de los enfoques y de las consiguientes referencias bibliográficas abordan la competitividad a nivel nacional siendo relativamente escasas las publicaciones sobre la competitividad urbana. Así, los documentos abordan una descripción general de las ciudades, las causas de las crisis y las consecuencias para la ciudad y su estructura económica, analizadas a partir de los impactos sobre el mercado laboral, los precios de la vivienda, el desarrollo del turismo, entre otros, y las diversas estrategias que adoptaron para afrontar la crisis y convertirla en una oportunidad de desarrollo.

Nuclear fuel cycles: interfaces with the environment

The waste materials generated in the nuclear fuel cycle are very varied,ranging from the tailings arising from mining and processing uranium ore, depleted uranium in a range of chemical forms, to a range of process wastes of differing activities and properties. Indeed, the wastes generated are intimately linked to the options selected in operating the nuclear fuel cycle, most obviously to the management of spent fuel. An open fuel cycle implies the disposal of highly radioactive spent fuel, whereas a closed fuel cycle generates a complex array of waste streams. On the other hand, a closed fuel cycle offers options for waste management, for example reduction in highly active waste volume, decreased radiotoxicity, and removal of fissile material. Many technological options have been proposed or explored, and each brings its own particular mix of wastes and environmental challenges.

Nuclear Mentalities? Strategies and Beliefs in Britain, France and the FRG

This is volume II of my two-volume study of the nuclear strategies/strategy preferences of Britain, France and West Germany in the Cold War. It shows that the great variable is the mentalities, culture, and particular interpretations of particular historical experiences of these three countries. These mental frameworks are reconstructed, in the tradition of the French Annales/Mentalite schools (that in turn is rooted in anthropology) by looking at a very large nunber of public texts in the context of the public discourse about nuclear strategy in each country.

Techno-economic Appraisal of Concentrating Solar Power Systems (CSP)

The diffusion of Concentrating Solar Power Systems (CSP) systems is currently taking place at a much slower pace than photovoltaic (PV) power systems. This is mainly because of the higher present cost of the solar thermal power plants, but also for the time that is needed in order to build them. Though economic attractiveness of different Concentrating technologies varies, still PV power dominates the market. The price of CSP is expected to drop significantly in the near future and wide spread installation of them will follow. The main aim of this project is the creation of different relevant case studies on solar thermal power generation and a comparison betwwen them. The purpose of this detailed comparison is the techno-economic appraisal of a number of CSP systems and the understanding of their behaviour under various boundary conditions. The CSP technologies which will be examined are the Parabolic Trough, the Molten Salt Power Tower, the Linear Fresnel Mirrors and the Dish Stirling. These systems will be appropriatly sized and simulated. All of the simulations aim in the optimization of the particular system. This includes two main issues. The first is the achievement of the lowest possible levelized cost of electricity and the second is the maximization of the annual energy output (kWh). The project also aims in the specification of these factors which affect more the results and more specifically, in what they contribute to the cost reduction or the power generation. Also, photovoltaic systems will be simulated under same boundary conditions to facolitate a comparison between the PV and the CSP systems. Last but not leats, there will be a determination of the system which performs better in each case study.

Responsabilidade social corporativa : a memória do Programa de Reassentamento dos Atingidos pela Barragem da Usina Hidrelétrica Luiz Gonzaga (ex-Itaparica)

No Brasil, água e energia têm uma forte e histórica nterdependência, de forma que a contribuição da energia hidráulica ao desenvolvimento econômico do País tem sido expressiva, seja no atendimento às diversas demandas da economia, ou da própria sociedade, melhorando o conforto das habitações e a qualidade de vida das pessoas. Também desempenha papel importante na integração e desenvolvimento de regiões distantes dos grandes centros urbanos e industriais. A década de 70 registrou um crescimento elevado da demanda por energia elétrica no Brasil; reflexo de políticas desenvolvimentistas de governos anteriores que promoveram o crescimento industrial do País atraindo e criando indústrias de uso alto intensivo da letricidade. No caso da região Nordeste, o crescimento econômico trouxe consigo o risco de um grave racionamento de energia. Para eliminar tal risco, o Estado por intermédio do Sistema Eletrobras realizou a construção de grandes usinas hidrelétricas interligando-as ao sistema nacional. Não há como negar que esta solução provocou um grande benefício para grande parte da população brasileira, mas trouxe, para uma parcela do povo brasileiro, um custo social bastante elevado. Essas pessoas ficaram então conhecidas como os “atingidos por barragens”. Para eles, a construção das barragens de usinas como Itaipu, Tucuruí, Sobradinho e Itaparica significou o deslocamento compulsório dos locais aonde viviam e tinham suas tradições e referência culturais e afetivas. Esta pesquisa objetiva resgatar a memória deste período de grandes obras, promessas de desenvolvimento e marcas deixadas em milhares de famílias brasileiras. O estudo em questão é também uma tentativa de mostrar como o Programa de Reassentamento de Itaparica, projeto conduzido pela Companhia Hidro Elétrica do São Francisco – CHESF foi o marco de uma nova dinâmica para tratamento das questões sociais envolvendo a reparação de danos causados aos atingidos por barragens e se constitui talvez, no primeiro caso de Responsabilidade Social Corporativa do setor elétrico brasileiro.

Potencialidade energética em diferentes extratores e tempos de extração do óleo de pinhão-manso (jatropha curcas l.) em soxletter

The current rhythm of petroliferous exploration is esteem that the existing reserves will be depleted in next the 45 years. Thus being, it has that to study intensely, what it has come to be fact, the alternative power plants, as well as the technologies economically capable to ultilizar them. The potential demand of biodiesel for 2020 is taken in consideration that, in accordance with the International Agency of Energia (AIE), in only eight countries, will jump of 34,7 million tons in 2010 for 133,8 million in 2020, with an increment next to 300%. The tame nut is a producing oil plant with all the qualities necessary to be transformed into oil diesel. Beyond perennial and of easy culture, it presents good conservation of the harvested seed, being able to become great producer of substance cousin as optional fuel source. For these authors, this is a culture that can be developed in the small properties, with the available familiar man power, being plus a source of income for the country properties of the Northeast Region. The objective of this work is to evidence the capacity of oil production of the nut-bellwether, and the quality of extration with hexano and methanol in 6 distinct times.

Spinning reserve opportunity cost in hydroelectric plants

Starting from the deregulated process of the Electric Sector, there was the need to attribute responsibilities to several agents and to elaborate appropriate forms of remuneration of the services rendered by the same. One of the services of great importance within this new electric sector is the Ancillary Services. Among the various types of Ancillary Services, Spinning Reserve is a service necessary for maintaining the integrity of the transmission system from either generation interruptions or load variations. This paper uses the application of the Economic Dispatch theory with the objective of quantifies the availability of Spinning Reserve supply in hydroelectric plants. The proposed methodology utilizes the generating units as well as their efficiencies so as to attend the total demand with the minimum water discharge. The proposed methodology was tested through the data provided by the Água Vermelha Hydroelectric Power Plant. These tests permitted the opportunity cost valuation to the Spinning Reserve supply in hydroelectric plants. © 2005 IEEE.

Sustainable urban energy planning: The case study of a tropical city

The urbanization of modern societies has imposed to the planners and decision-makers a more precise attention to facts not considered before. Several aspects, such as the energy availability and the deleterious effect of pollution on the populations, must be considered in the policy decisions of cities urbanization. The current paradigm presents centralized power stations supplying a city, and a combination of technologies may compose the energy mix of a country, such as thermal power plants, hydroelectric plants, wind systems and solar-based systems, with their corresponding emission pattern. A goal programming multi-objective optimization model is presented for the electric expansion analysis of a tropical city, and also a case study for the city of Guaratinguetá, Brazil, considering a particular wind and solar radiation patterns established according to actual data and modeled via the time series analysis method. Scenarios are proposed and the results of single environmental objective, single economic objective and goal programming multi-objective modeling are discussed. The consequences of each dispatch decision, which considers pollutant emission exportation to the neighborhood or the need of supplementing electricity by purchasing it from the public electric power grid, are discussed. The results revealed energetic dispatch for the alternatives studied and the optimum environmental and economic solution was obtained. © 2012 Elsevier Ltd.
