Uma nova proposta de fluidos de perfuração aquosos à base de polímeros vinílicos e bentonita para poços de alta temperatura e pressão

The advance of drilling in deeper wells has required more thermostable materials. The use of synthetic fluids, which usually have a good chemical stability, faces the environmental constraints, besides it usually generate more discharge and require a costly disposal treatment of drilled cuttings, which are often not efficient and require mechanical components that hinder the operation. The adoption of aqueous fluids generally involves the use of chrome lignosulfonate, used as dispersant, which provides stability on rheological properties and fluid loss under high temperatures and pressures (HTHP). However, due to the environmental impact associated with the use of chrome compounds, the drilling industry needs alternatives that maintain the integrity of the property and ensure success of the operation in view of the strong influence of temperature on the viscosity of aqueous fluids and polymers used in these type fluids, often polysaccharides, passives of hydrolysis and biological degradation. Therefore, vinyl polymers were selected for this study because they have predominantly carbon chain and, in particular, polyvinylpyrrolidone (PVP) for resisting higher temperatures and partially hydrolyzed polyacrylamide (PHPA) and clay by increasing the system's viscosity. Moreover, the absence of acetal bonds reduces the sensitivity to attacks by bacteria. In order to develop an aqueous drilling fluid system for HTHP applications using PVP, HPAM and clay, as main constituents, fluid formulations were prepared and determined its rheological properties using rotary viscometer of the Fann, and volume filtrate obtained by filtration HTHP following the standard API 13B-2. The new fluid system using polyvinylpyrrolidone (PVP) with high molar weight had higher viscosities, gels and yield strength, due to the effect of flocculating clay. On the other hand, the low molecular weight PVP contributed to the formation of disperse systems with lower values in the rheological properties and fluid loss. Both systems are characterized by thermal stability gain up to around 120 ° C, keeping stable rheological parameters. The results were further corroborated through linear clay swelling tests.

Independent Projects Environmental Studies 2010: From Climate Change Laggard to Leader: Policy recommedations for Newfoundland and Labrador

Dyer, along with many others reflecting international consensus in the scientific community, argues that countries must be carbon neutral by 2050 to avoid the worst impacts of climate change (Dyer, 2008, p. xii). to accomplish this by 2050, we need to act now: governments need to cooperate with the scientific community to ensure our society makes the changes to combat climate change. How is Canada reacting to this situation? As describes by the Sierra Club of Canada, "federal government continues to drag its feet, and delay any action to reduce emissions" (2008, p. 18). Given this federal reluctance, individual provinces must act to reduce emissions. While some provinces take a required action, primarily Quebec and British Columbia, others, like Newfoundland and Labrador, contribute little in terms of emissions reductions. Newfoundland and Labrador is ranked as "poor"-among the worst performers regarding climate change policy in the country-by the David Suzuki Foundation in a cross Canada evaluation of various provincial climate change policies (David Suzuki Foundation, 2008, p. 9). The Province of Newfoundland is not doing enough to address climate change. In this paper I argue that to improve this situation, the province could follow the example of the two leading jurisdictions, Quebec and British Columbia, to refine and introduce its own hybrid policy that directly affects decision making processes. But, this can be complicated when convincing the government that it is important to accept stronger policy. The government must consider what climate change impacts Newfoundland and Labrador experiences and willconinue to experience and what Newfoundland and Labrador is contributing to the problem of climate change. To evaluate these issues of climate change, I first survey the positive policies Newfoundland and Labrador is currently implementing/ discussing and then outline action taken by the provincial environment leaders, Quebec and British Columbia.Then I describe the strong pieces in the Quebec and British Columbia climate change action plan that Newfoundland and Labrador can emulate. Finally, I consider if thes polices are politically feasible for the government of Newfoundland and labrador. Hence, this paper aims to give a blueprint of what Newfoundland and Labrador has to act on to make itself an environmental leader.

Bogusław Śliwa (1944-1989) - działacz opozycji demokratycznej i "Solidarności" w Kaliszu

Bogusław Śliwa was born in Lvov on 6 October 1944. He graduated in law studies at Adam Mickiewicz University in Poznań in 1969. Following the completion of his prosecutor’s apprenticeship he worked, among others, in Wolsztyn, Świebodzin and – from 1975 – in Kalisz. On 22 August 1978 Śliwa was fired from the public prosecutor’s office because he had attempted to detect a person who murdered during the robbery committed by a Civic Militia officer. That time he established and maintained close contacts with activists of the Workers’ Defence Committee (KOR), among others: Jacek Kuroń, Mirosław Chojecki, Adam Michnik, Bronisław Geremek, Jan Lityński, Zofia Romaszewska and Zbigniew Romaszewski. In 1978 he began to cooperate with the Kalisz group of the Movement for the Defence of Human and Civil Rights (ROPCiO). In the early 1979 this group started to publish “Wolne Słowo” in which Śliwa was a co-editor. On 28 June 1979 in Poznań he was involved in founding the Social Self-Defence Club of the Wielkopolska and Kujawy Region. In September 1980, during strikes at the FWR “Runotex” and KZKS “Winiary” in Kalisz Śliwa was an expert representing the workers. On 29 September of that year, he arranged in Kalisz a meeting of representatives and delegates of enterprises in Kalisz aimed at appointing the Board of the Inter-Enterprise Founding Committee of the Independent Self-Governing Trade Union. He became the secretary. Bogusław Śliwa also engaged in setting up and developing an information team. He was informally responsible for developing an information and printing base. Bogusław Śliwa set up “NSZZ Solidarność” magazine where he published his own articles. He also founded the “Solidarność” Workers’ Community Centre in Kalisz. it is noteworthy that it was the only community centre in Poland established by „Solidarność”. In December the Nationwide Liaison Commission of „Solidarność” appointed him to the Committee for the Defence of Prisoners of Conscience established on 10 December of that year. He participated in the information meeting of the Independent Self-Governing Trade Union of Independent Farmers “Solidarność Wiejska” held in Staw, in Szczytniki commune. During that meeting “Solidarność Wiejska” led by Mieczysław Walczykiewicz requested the authorities to liquidate the “Świt” Agricultural Production Cooperative in Cieszyków, in Szczytniki commune. Bogusław Śliwa was involved in this successful event. It was the first liquidation of cooperative in Poland. On 11 January 1981 Śliwa co-organized the 1st Regional Convention of „Solidarność” Wiejska in Kalisz. Following the so-called Bydgoszcz events of 19 March 1981 he advocated the general strike. Due to his attitude, Śliwa was listed as one of 146 „Solidarność” activists executed by the 3rd “A” Department of the Ministry of Internal Affairs. According to the authorities those activists presented radical views. On 30 June 1981 at the 1st General Delegates Convention of the Kaliskie province, Śliwa, as a delegate of the Kaliskie province, was appointed to the Regional Board of „Solidarność” – Southern Wielkopolska. In July Śliwa set up in Kalisz the underground branch of the Polish Democratic Party. In 1981 Śliwa was a delegate to the 1st National Delegates Convention of „Solidarność” and co-edited with Jan Lityński the document entitled: “Message to the Working People of Eastern Europe” originated by Henryk Siciński and adopted by the 1st National Delegates Convention. On 22 November he participated in the Warsaw-held meeting founding the Self-Governing Republic Clubs “Liberty – Equality– Independence” and signed the founding declaration. On 28 of that month he co-organized with Antoni Pietkiewicz a founding meeting of the Club in Kalisz. When martial law was declared he began to hide in Kalisz. Śliwa was arrested on 25 February 1982 and interned in Ostrów Wielkopolski and then in Gębarzew and Kwidzyn. After being released on 25 November 1982, he was immediately involved in the activity of the underground movement of „Solidarność”. He edited the first two issues of “Nasza Solidarność” magazine published in Kalisz. Śliwa co-invented and co-organized the 1st May march that was independent from the authorities’ one held in Kalisz in 1983. Consequently, he was temporarily arrested and detained in Ostrów Wielkopolski. On 7 June 1983 he was released from custody. The amnesty declared on 21 July 1983 caused that the investigation against him was discontinued. In July of the same year he co-founded the Inter-Regional Coordination Commission of the Independent Self-Governing Trade Union “Solidarność” Kalisz-Konin-Sieradz. As he could not find any work and he and his family were exposed to psychological harassment, he emigrated to Sweden on 30 December 1983. He worked, among other positions, as bookbinder. He was the board secretary of the Congress of Poles in Sweden. In 1984 he commented the death of priest Jerzy Popiełuszko in “Dagens Nyheter” daily. He was also interviewed by Radio Liberty. Śliwa commenced cooperating with representatives of the „Solidarność” Coordination Office in Paris, Brussels and Stockholm. On 18 April 1985 the Military Garrison Prosecutor’s Office in Wrocław initiated investigations against Śliwa, charging him with activities detrimental to political interests of the People’s Republic of Poland. Subsequently, on 10 July 1985 this public prosecutor’s office decided to issue an arrest warrant for him. On the same day the public prosecutor suspended criminal proceedings against him. In December 1985, after the courageous escape of two brothers, Adam and Krzysztof Zieliński, from Poland to Sweden, he helped them prevent their deportation and stay in their new homeland. He expressed his opinion on this issue on Swedish television and in “ Dagens Nyheter” daily. His intervention helped them legally stay in Sweden. In 1989 he arrived in Poland. During this short visit he met and talked with his colleagues from the so-called first „Solidarność”. Bogusław Śliwa died in Stockholm on 23 November 1989. He was buried there on 7 December 1989. On 18 October 2006 he was posthumously honoured by Lech Kaczynski, President of Poland, with the Order of Polonis Restitution. On 15 June 2007 Bogusław Śliwa was posthumously granted the title of an Honorary Citizen of Kalisz by the Town Council of Kalisz.

Cenário evolutivo da educação ambiental para o desenvolvimento sustentável no mundo: etapas e promotores

Desde a publicação do livro Silent Spring, 1962, de Rachel Carson, do livro The Limits to Growth, 1972, do Clube de Roma e do impacto provocado pelo Relatório Brundtland, Our Common Future, 1987, pela World Commission on Environment and Development, que os organismos internacionais se envolvem em parcerias e assinam declarações de compromisso com a Educação Ambiental para o Desenvolvimento Sustentável – EADS. O objetivo do presente artigo é realizar uma narrativa sobre os eventos dedicados à EADS, com início na Conferência de Estocolmo até à Conferência do Rio+20. O estudo teve como base metodológica uma revisão crítica da literatura. Concluiu-se que a sociedade tomou maior consciência sobre os problemas ambientais a partir de 1970. Despontaram as primeiras respostas político-administrativas na Conferência de Estocolmo e, mais tarde, publicou-se a Informação Brundtland pela equipa interdisciplinar de experts em meio ambiente. Daqui resultaram o Tratado de Bem-estar (garantia dos direitos mínimos aos cidadãos pelo Estado) e o conceito de Desenvolvimento Sustentável. Surgiu assim a solidariedade social para com o futuro da humanidade, que implicou o princípio de “não hipotecar os recursos das gerações futuras”. Na Conferência do Rio a EADS foi plenamente aceite e divulgada pelo mundo. Todavia, com a entrada do novo milénio, a atenção dada à EADS regrediu significativamente.

Down, You Vagabond of a Heart! : Romance and Created Personas in the Journals of L. M. Montgomery

Kanadalainen kirjailija L. M. (Ludy Maud) Montgomery (1874-1942) tunnetaan parhaiten lasten ja nuorten kirjallisuudestaan, erityisesti Anne of Green Gables -romaanistaan (suom. Annan nuoruusvuodet). Graduni tutkii kuitenkin Montgomeryn vähemmän tunnettua omaelämäkerrallista tuotantoa, hänen päiväkirjojaan, jotka on julkaistu viidessä osassa (1985-2004). Keskityn romanssin kuvaukseen Montgomeryn päiväkirjojen ensimmäisessä osassa ja tutkin, millaisia tekstuaalisia persoonia (personas) kertoja luo autobiografisessa prosessissa. Tähän narratiiviseen prosessiin vaikuttavat erityisesti päiväkirjan yleisö tai lukijat (audience), samoin kuin fiktiiviset esikuvat ja fiktiivisesti kirjoittaminen (fictionalisation) sekä kysymys päiväkirjan kertovasta ja kerrotusta minästä (narrated and narrating I). Romanssi on pääosassa Montgomeryn päiväkirjojen ensimmäisessä julkaistussa osassa, joka kuvaa hänen teini- ja varhaisaikuisuusvuosiaan. Väitän, että vaikka päiväkirjateksti saattaa vaikuttaa rehelliseltä ja todenmukaiselta kuvaukselta elämästä, varsinkin Montgomeryn tapauksessa kyseessä on silti läpikotaisin editoitu ja muokattu teksti, jota päiväkirjan tekijä hallitsee rautaisella otteella ja joka käyttää hyväkseen fiktiivisiä keinoja. Aineistonani käytän sekä Montgomeryn julkaistuja että julkaisemattomia päiväkirjoja, joita säilytetään University of Guelphin arkistoissa, Kanadan Ontariossa. Päiväkirjat ovat moneen kertaan sekä Montgomeryn että julkaistujen päiväkirjojen editoijien muokkaamia, joten niiden tutkiminen lähilukemalla (close-reading) ja eri versioita vertaillen on erityisen tärkeää. Teorian osalta keskityn lähinnä Pohjois-Amerikassa kirjoitettuun autobiografia- ja (naisten) päiväkirjatutkimukseen. Väitän gradussani, että Montgomeryn kuvaus heteroseksuaalisesta romanssista välttää tarjoamasta lukijalle romanssijuonen tyypillistä katharsista. Montgomeryn romanttiset persoonat ovat yllättävän epäromanttisia ja ristiriidassa keskenään. Romantiikan traditiolle tyypillistä kieltä ja personifikaatiota käytetään joko korostetun liioitellusti tai humoristisesti ja parodioiden.
