Contemporary engagements within corridors of the past: temporal elasticity, graffiti, and the materiality of St. Rock Street, Barcelona

In a medieval Barcelonan side-street, urine, rubbish, and a bewildering array of graphic imagery splatters the narrowing walls between two major thoroughfares. A contemporary conflict between residents, unknown artists and others is played out using banners, bottles, stickers, posters, stencils, spray paint, and bodily substances. In this shadowed liminality, local and global debates are superimposed upon substructures constructed from disease, prostitution, and the Saint of the Plague. The continuing urban struggle constitutes temporal statements of dirt and purity, violence and humour, dominance and resistance, death and salvation. Like the renovated facades masking the crumbling remains of structures long neglected, the government’s literal whitewashing of the art is a temporal cover-up of a discursive symptom stretching from deeply embedded preconditions. However, from his niche in the angular bend of the alley bearing his name, the statue of St. Rock remains unblinkingly staring, raised above the contestations expressed below.

Japanin musiikkimarkkinat : Japanin pop- ja rock-markkinoiden erityispiirteet suomalaisen musiikin näkökulmasta

Tämän opinnäytetyön tavoite on selvittää suomalaisen pop- ja rock-musiikin vientimahdollisuuksia yhteen maailman kiinnostavimpaan ja ostovoimaisimpaan maahan, Japaniin, ja tuoda esille sen luonnetta suhteessa suomalaiseen musiikkiin. Opinnäytetyön teoriaosa selvittää Suomen tämän hetkistä musiikkiviennin tilannetta ja syitä siihen, miksi Japanin markkinat on erittäin kiinnostava alue viennin saralla. Kirjallinen viitekehys työlle muodostuu pääasiassa kootuista musiikkialan raporteista, tilastoista ja artikkeleista. Empiirisessä osassa keskeistä tutkimusmateriaalia ovat Tokion Suomen Instituutissa kolmen kuukauden työharjoittelun yhteydessä kertyneet kokemukset ja asiantuntijahaastatteluaineisto. Nämä avaavat Japanin musiikkimarkkinoita luoden parempaa kuvaa siellä vallitsevista kilpailuolosuhteista, maan tavoista ja kiinnostuksen kohteista, sekä japanilaisten mielikuvaa suomalaisesta musiikista. Suomessa musiikkimarkkinat ovat hyvin pienet, mutta niiden laajentamiseen viennillä on alettu keskittyä yhä enenevissä määrin. Koska Japanissa on maailman toiseksi suurimmat musiikkimarkkinat, se on erittäin varteenotettava kohde myös suomalaisen musiikin viennille. Vaikka suomalainen musiikki on toistaiseksi suhteellisen tuntematonta suurelle osalle japanilaisista, suhtaudutaan siihen positiivisesti. Japanilaisten mielestä Suomesta tuleva musiikki on verrattuna moniin muihin maihin paljon omaleimaisempaa ja tämä tekee siitä kiinnostavan. Viennissä ongelmia kuitenkin luovat kielimuuri ja japanilaisten kulttuurisidonnaiset toimintatavat. Ilman hyviä suhteita toiminta Japanin musiikkialan kentällä on lähes mahdotonta. Keskeistä on huomioida paikalliset toimintatavat ja toimia kiireettä kaukonäköisesti. Tuotteen kaikkien osa-alueiden tulisi olla suunniteltu Japanin markkinoihin soveltuviksi jo tarjontavaiheessa. Parantaakseen suomalaisen musiikin vientiä Japaniin on tärkeää tuotteiden menestyksien yhteydessä tuoda esille niiden suomalaisuutta ja näin lisätä kiinnostusta japanilaisten silmissä. Lähtökohtaisesti suomalaisella musiikilla on kuitenkin hyvät mahdollisuudet menestykseen Japanin musiikkimarkkinoilla. Suurimpina ongelmina voidaan pitää vähäistä tietoa japanilaisten mielenkiinnon kohteista, toimintatapojen kulttuurisia eroja ja suomalaisten vientiin panostettavien varojen vähyyttä.

Production of Mg(OH)2 from Mg-silicate rock for CO2 mineral sequestration

Sequestration of carbon dioxide in mineral rocks, also known as CO2 Capture and Mineralization (CCM), is considered to have a huge potential in stabilizing anthropogenic CO2 emissions. One of the CCM routes is the ex situ indirect gas/sold carbonation of reactive materials, such as Mg(OH)2, produced from abundantly available Mg-silicate rocks. The gas/solid carbonation method is intensively researched at Åbo Akademi University (ÅAU ), Finland because it is energetically attractive and utilizes the exothermic chemistry of Mg(OH)2 carbonation. In this thesis, a method for producing Mg(OH)2 from Mg-silicate rocks for CCM was investigated, and the process efficiency, energy and environmental impact assessed. The Mg(OH)2 process studied here was first proposed in 2008 in a Master’s Thesis by the author. At that time the process was applied to only one Mg-silicate rock (Finnish serpentinite from the Hitura nickel mine site of Finn Nickel) and the optimum process conversions, energy and environmental performance were not known. Producing Mg(OH)2 from Mg-silicate rocks involves a two-staged process of Mg extraction and Mg(OH)2 precipitation. The first stage extracts Mg and other cations by reacting pulverized serpentinite or olivine rocks with ammonium sulfate (AS) salt at 400 - 550 oC (preferably < 450 oC). In the second stage, ammonia solution reacts with the cations (extracted from the first stage after they are leached in water) to form mainly FeOOH, high purity Mg(OH)2 and aqueous (dissolved) AS. The Mg(OH)2 process described here is closed loop in nature; gaseous ammonia and water vapour are produced from the extraction stage, recovered and used as reagent for the precipitation stage. The AS reagent is thereafter recovered after the precipitation stage. The Mg extraction stage, being the conversion-determining and the most energy-intensive step of the entire CCM process chain, received a prominent attention in this study. The extraction behavior and reactivity of different rocks types (serpentinite and olivine rocks) from different locations worldwide (Australia, Finland, Lithuania, Norway and Portugal) was tested. Also, parametric evaluation was carried out to determine the optimal reaction temperature, time and chemical reagent (AS). Effects of reactor types and configuration, mixing and scale-up possibilities were also studied. The Mg(OH)2 produced can be used to convert CO2 to thermodynamically stable and environmentally benign magnesium carbonate. Therefore, the process energy and life cycle environmental performance of the ÅAU CCM technique that first produces Mg(OH)2 and the carbonates in a pressurized fluidized bed (FB) were assessed. The life cycle energy and environmental assessment approach applied in this thesis is motivated by the fact that the CCM technology should in itself offer a solution to what is both an energy and environmental problem. Results obtained in this study show that different Mg-silicate rocks react differently; olivine rocks being far less reactive than serpentinite rocks. In summary, the reactivity of Mg-silicate rocks is a function of both the chemical and physical properties of rocks. Reaction temperature and time remain important parameters to consider in process design and operation. Heat transfer properties of the reactor determine the temperature at which maximum Mg extraction is obtained. Also, an increase in reaction temperature leads to an increase in the extent of extraction, reaching a maximum yield at different temperatures depending on the reaction time. Process energy requirement for producing Mg(OH)2 from a hypothetical case of an iron-free serpentine rock is 3.62 GJ/t-CO2. This value can increase by 16 - 68% depending on the type of iron compound (FeO, Fe2O3 or Fe3O4) in the mineral. This suggests that the benefit from the potential use of FeOOH as an iron ore feedstock in iron and steelmaking should be determined by considering the energy, cost and emissions associated with the FeOOH by-product. AS recovery through crystallization is the second most energy intensive unit operation after the extraction reaction. However, the choice of mechanical vapor recompression (MVR) over the “simple evaporation” crystallization method has a potential energy savings of 15.2 GJ/t-CO2 (84 % savings). Integrating the Mg(OH)2 production method and the gas/solid carbonation process could provide up to an 25% energy offset to the CCM process energy requirements. Life cycle inventory assessment (LCIA) results show that for every ton of CO2 mineralized, the ÅAU CCM process avoids 430 - 480 kg CO2. The Mg(OH)2 process studied in this thesis has many promising features. Even at the current high energy and environmental burden, producing Mg(OH)2 from Mg-silicates can play a significant role in advancing CCM processes. However, dedicated future research and development (R&D) have potential to significantly improve the Mg(OH)2 process performance.

Uso do fixador esquelético externo Tipo II para osteossíntese de tibiotarso em galinhas da raça Plymouth Rock Branca: modelo experimental para uso em aves selvagens

Foi avaliada a eficiência do fixador esquelético externo Tipo II para o tratamento de fratura de tibiotarso em oito galinhas adultas da raça Plymouth Rock Branca. As aves foram pré-medicadas com sulfato de morfina e anestesiadas com halotano. Em seguida, foi realizada osteotomia na diáfise do tibiotarso esquerdo, por meio de serra oscilatória. Quatro pinos de Kirschner foram inseridos através das corticais ósseas, dois proximalmente e dois distalmente ao foco da fratura. Após a redução desta, as extremidades dos dois pinos proximais e distais foram torcidas em direção distal ou proximal, respectivamente, sendo os pinos conectados externamente por meio de duas barras de acrílico autopolimerizável, nas faces lateral e medial externa do membro. O retorno da plena capacidade de utilização do membro foi observado em 20,00±7,09 dias, e a cicatrização óssea, avaliada por exame radiográfico, ocorreu em 35,12±8,72 dias. Os resultados do experimento demonstraram que redução aberta e aplicação de fixador esquelético externo Tipo II é método efetivo para o tratamento de fraturas de tibiotarso em galinhas da raça Plymouth Rock Branca.
