The Clarence-Moreton Basin (CMB) covers approximately 26000 km2 and is the only sub-basin of the Great Artesian Basin (GAB) in which there is flow to both the south-west and the east, although flow to the south-west is predominant. In many parts of the basin, including catchments of the Bremer, Logan and upper Condamine Rivers in southeast Queensland, the Walloon Coal Measures are under exploration for Coal Seam Gas (CSG). In order to assess spatial variations in groundwater flow and hydrochemistry at a basin-wide scale, a 3D hydrogeological model of the Queensland section of the CMB has been developed using GoCAD modelling software. Prior to any large-scale CSG extraction, it is essential to understand the existing hydrochemical character of the different aquifers and to establish any potential linkage. To effectively use the large amount of water chemistry data existing for assessment of hydrochemical evolution within the different lithostratigraphic units, multivariate statistical techniques were employed.

Using a combination of multivariate statistical techniques and the graphical assessment of major ion ratios, the influences on hydrochemical variability of coal seam gas (or coal bed methane) groundwaters from several sites in the Surat and Clarence-Moreton basins in Queensland, Australia, were investigated. Several characteristic relationships between major ions were observed: 1) strong positive linear correlation between the Na/Cl and alkalinity/Cl ratios; 2) an exponentially decaying trend between the Na/Cl and Na/alkalinity ratios; 3) inverse linear relationships between increasing chloride concentrations and decreasing pH for high salinity groundwaters, and; 4) high residual alkalinity for lower salinity waters, and an inverse relationship between decreasing residual alkalinity and increasing chloride concentrations for more saline waters. The interpretation of the hydrochemical data provides invaluable insights into the hydrochemical evolution of coal seam gas (CSG) groundwaters that considers both the source of major ions in coals and the influence of microbial activity. Elevated chloride and sodium concentrations in more saline groundwaters appear to be influenced by organic-bound chlorine held in the coal matrix; a sodium and chloride ion source that has largely been neglected in previous CSG groundwater studies. However, contrastingly high concentrations of bicarbonate in low salinity waters could not be explained, and are possibly associated with a number of different factors such as coal degradation, methanogenic processes, the evolution of high-bicarbonate NaHCO3 water types earlier on in the evolutionary pathway, and variability in gas reservoir characteristics. Using recently published data for CSG groundwaters in different basins, the characteristic major ion relationships identified for new data presented in this study were also observed in other CSG groundwaters from Australia, as well as for those in the Illinois Basin in the USA. This observation suggests that where coal maceral content and the dominant methanogenic pathway are similar, and where organic-bound chlorine is relatively abundant, distinct hydrochemical responses may be observed. Comparisons with published data of other NaHCO3 water types in non-CSG environments suggest that these characteristic major ion relationships described here can: i) serve as an indicator of potential CSG groundwaters in certain coal-bearing aquifers that contain methane; and ii) help in the development of strategic sampling programmes for CSG exploration and to monitor potential impacts of CSG activities on groundwater resources.

Empire is central to U.S. history. When we see the U.S. projecting its influence on a global scale in today s world it is important to understand that U.S. empire has a long history. This dissertation offers a case study of colonialism and U.S. empire by discussing the social worlds, labor regimes, and culture of the U.S. Army during the conquest of southern Arizona and New Mexico (1866-1886). It highlights some of the defining principles, mentalities, and characteristics of U.S. imperialism and shows how U.S. forces have in years past constructed their power and represented themselves, their missions, and the places and peoples that faced U.S. imperialism/colonialism. Using insights from postcolonial studies and whiteness studies, this work balances its attention between discursive representations (army stories) and social experience (army actions), pays attention to silences in the process of historical production, and focuses on collective group mentalities and identities. In the end the army experience reveals an empire in denial constructed on the rule of difference and marked by frustration. White officers, their wives, and the white enlisted men not only wanted the monopoly of violence for the U.S. regime but also colonial (mental/cultural) authority and power, and constructed their identity, authority, and power in discourse and in the social contexts of the everyday through difference. Engaged in warfare against the Apaches, they did not recognize their actions as harmful or acknowledge the U.S. invasion as the bloody colonial conquest it was. White army personnel painted themselves and the army as liberators, represented colonial peoples as racial inferiors, approached colonial terrain in terms of struggle, and claimed that the region was a terrible periphery with little value before the arrival of white civilization. Officers and wives also wanted to place themselves at the top of colonial hierarchies as the refined and respectable class who led the regeneration of the colony by example: they tried to turn army villages into islands of civilization and made journeys, leisure, and domestic life to showcase their class sensibilities and level of sophistication. Often, however, their efforts failed, resulting in frustration and bitterness. Many blamed the colony and its peoples for their failures. The army itself was divided by race and class. All soldiers were treated as laborers unfit for self-government. White enlisted men, frustrated by their failures in colonial warfare and by constant manual labor, constructed worlds of resistance, whereas indigenous soldiers sought to negotiate the effects of colonialism by working in the army. As colonized labor their position was defined by tension between integration and exclusion and between freedom and colonial control.

Tarkastelen pro gradu -tutkielmassani naiskysymystä Seitsemännen päivän adventtikirkon oppiäiti Ellen Whiten (1827 1915) terveysopetuksessa. White tunnetaan ennen kaikkea näyistään, joiden välityksellä hän koki saavansa Jumalalta hyvinvointiin liittyviä ohjeita. White kirjoitti näkyjensä innoittama terveysoppaita ja julisti pääasiassa Yhdysvalloissa yli 70 vuotta. Päälähteenäni ovat kaksi Whiten omaelämäkertaa vuosilta 1880 ja 1915 sekä 83 artikkelia, jotka hän julkaisi adventistien johtavassa terveyslehdessä, Health Reformerissa, vuosina 1866 1878. Tutkimuskysymykseni ovat, miksi White osoitti lähes kaiken terveyteen liittyvän opetuksensa naisille ja miten hän ymmärsi terveyden osana naisen roolia ja tehtäviä. Tulkintani mukaan White julisti naisille, sillä hän uskoi, että naisen asema oli selkeytettävä. Yhdysvallat teollistui ja kaupungistui nopeasti 1800-luvulla, mikä aiheutti naisille taloudellisia, sosiaalisia ja terveyteen liittyviä ongelmia. Lisäksi toinen suuri herätys (1800 1830) synnytti keskustelua naisen roolista. Monet kirkot antoivat naisille luvan esimerkiksi saarnaamiseen, mutta Yhdysvalloissa vahvistui samaan aikaan myös käsitys naisesta kodin uskonnollisena johtajana. Ymmärrän, että Whiten mukaan ratkaisu naisen sekavaan asemaan oli terveys. Uskon, että Whiten mukaan nainen pystyi ottamaan oman paikkansa yhteiskunnassa, mikäli hän pysyi terveenä ja oppi tuntemaan terveyden periaatteet. Toisaalta White sai vaikutteita naisten yhteiskunnallisten oikeuksien puolustajilta. He ajattelivat, että vain koulutettu ja terve nainen kykeni vapautumaan avioliitosta. Toisaalta White oli naisasianaisia maltillisempi. Hän ymmärsi, että vain terve ja terveyskoulutuksen saanut nainen saattoi olla hyvä äiti. Ellen White osallistui terveysopetuksellaan keskusteluun myös naisen uskonnollisesta roolista. White oli itse kiertelevä terveyssaarnaaja. Silti hän ymmärsi, että muiden naisten kutsumus oli olla terve ja koulutettu äiti. White korosti äitien pyhyyttä luultavasti siksi, että hän pyrki turvaamaan oman auktoriteettiasemansa Adventtikirkossa. White myös luultavasti ymmärsi roolinsa ja tehtävänsä poikkeuksellisiksi ja arvosti vilpittömästi äitiyttä. Whiten mukaan äidin tehtävä oli kasvattaa terveitä ja moraalisia kansalaisia. Tehtävän arvon hän perusteli aikansa tieteellisillä teorioilla. White korosti luonnontieteilijä Charles Darwinin (1809 1882) evoluutioteorian mukaisesti, että äidin velvollisuus oli siirtää lapsilleen hyvä terveys. Käsityksensä terveyden ja moraalin suhteesta hän selitti frenologialla, jonka mukaan ihmisen elämäntavat vaikuttivat hänen luonteenpiirteisiinsä. White oli myös todennäköisesti kiinnostunut sosiaalitieteilijä Herbert Spencerin (1820 1903) ajatuksista, joiden mukaan kansalaisten kehittyessä myös yhteiskunta jalostui yhä paremmaksi. Vaikka White perusteli opetustaan modernilla tieteellä, hän oli ennen kaikkea uskonnollinen julistaja. Hän kuului 1840-luvulla herätyssaarnaaja William Millerin (1782 1849) liikkeeseen, jonka jäsenet uskoivat, että Jumala tuhoaa Yhdysvallat viimeisellä tuomiolla, mikäli kansan moraalin tila ei nopeasti kohene. Millerin liikkeen painotukset säilyivät Adventtikirkossa, joka perustettiin vuonna 1863. Siten White ymmärsi, ettei äiti ollut vastuussa vain perheensä ja kansansa maallisesta hyvinvoinnista vaan myös heidän pelastuksestaan. Whiten käsitys äidistä on mielestäni ristiriitainen. White antoi äideille paljon valtaa, mutta myös suuren vastuun. Hän korosti äitien arvokkuutta, mutta toisaalta he eivät olleet hänen mukaansa korvaamattomia. White ei myöskään huomioinut naisia, jotka eivät olleet äitejä.

O objetivo deste trabalho foi avaliar se a expressão do colágeno tipo I, III e metaloproteinase podem estar relacionadas com o grau de Gleason, estadio patológico e PSA pré-operatório, e se isto poderia servir como prognóstico de doença. O grupo de estudo incluiu espécimes de prostatectomia radical de 33 pacientes com adenocarcinoma submetidos à cirurgia no período de 2001 a 2009. Os pacientes foram divididos em 3 grupos: grau de Gleason = 6 (13 pacientes), escore de Gleason = 7 (10 pacientes), escore de Gleason ≥ 8 (10 pacientes). O tecido prostático benigno adjacente à area de câncer nos graus de Gleason foi utilizado como grupo controle. As áreas de adenocarcinoma e de tecido benigno foram selecionados sob análise microscópica e processados para colágeno I e III sob análise do gene por PCR em Tempo Real. Dez seções desparafinadas de cada grupo foram utilizados para avaliar o colágeno I, III e a imunoexpressão de metaloproteinase. Os resultados foram relacionados com o grau de Gleason, PSA pré-operatório e estadio patológico. Apesar da diferença significativa na expressão gênica de ambos colágeno I e III entre as áreas de tecido prostático benigno e tumor nas amostras de próstata Gleason = 6 (colágeno I = 0,4 0,2 vs 5 2,4, p<0,05; colágeno III = 0,2 0,06 vs 0,7 0,1, p<0,05) e grau de Gleason ≥ 8 (I = 8 3,4 vs 1,4 0,8, p<0,05; colágeno III = 1,8 0,5 vs 0,6 0,1, p<0,05), não houve correlação com grau de Gleason, PSA pré-operatório ou estadio patológico. Houve uma correlação positiva entre a expressão de metaloproteinases e grau de Gleason (r2 = 0,47). Concluindo, tem-se que a correlação positiva entre a expressão de metaloproteinases e o grau de Gleason sugere que a metaloproteinase pode ser um fator promissor para melhorar o grau de Gleason. Sua expressão e regulação não parecem estar relacionados com a degradação do colágeno. Não há correlação entre expressão de colágeno e grau de Gleason, nem a nível gênico nem protéico.
