A Critical Evaluation of the MARS Treatment in Finland

The Molecular Adsorbent Recirculating System (MARS) is an extracorporeal albumin dialysis device which is used in the treatment of liver failure patients. This treatment was first utilized in Finland in 2001, and since then, over 200 patients have been treated. The aim of this thesis was to evaluate the impact of the MARS treatment on patient outcome, the clinical and biochemical variables, as well as on the psychological and economic aspects of the treatment in Finland. This thesis encompasses 195 MARS-treated patients (including patients with acute liver failure (ALF), acute-on-chronic liver failure (AOCLF) and graft failure), and a historical control group of 46 ALF patients who did not undergo MARS. All patients received a similar standard medical therapy at the same intensive care unit. The baseline data (demographics, laboratory and clinical variables) and MARS treatment-related and health-related quality-of-life data were recorded before and after treatment. The direct medical costs were determined for a period of 3.5 years.Additionally, the outcome of patients (survival, native liver recovery and need for liver transplantation) and survival predicting factors were investigated. In the outcome analysis, for the MARS-treated ALF patients, their 6-month survival (75% vs. 61%, P=0.07) and their native liver recovery rate (49% vs. 17%, P<0.001) were higher, and their need for transplantations was lower (29% vs. 57%, P= 0.001) than for the historical controls. However, the etiological distribution of the ALF patients referred to our unit has changed considerably over the past decade and the percentage of patients with a more favorable prognosis has increased. The etiology of liver failure was the most important predictor of the outcome. Other survival predicting factors in ALF included hepatic encephalopathy, the coagulation factors and the liver enzyme levels prior to MARS treatment. In terms of prognosis, the MARS treatment of the cirrhotic AOCLF patient seems meaningful only when the patient is eligible for transplantation. The MARS treatment appears to halt the progression of encephalopathy and reduce the blood concentration of neuroactive amino acids, albumin-bound and water-soluble toxins. In general, the effects of the MARS treatment seem to stabilize the patients, thus allowing additional time either for the native liver to recover, or for the patients to endure the prolonged waiting for transplantation. Furthermore, for the ALF patients, the MARS treatment appeared to be less costly and more cost-efficient than the standard medical therapy alone. In conclusion, the MARS treatment appears to have a beneficial effect on the patient outcome in ALF and in those AOCLF patients who can be bridged to transplantation.

The Finnish Competition State and Entrepreneurial Policies in the Helsinki Region

The thesis examines the intensification and characteristics of a policy that emphasises economic competitiveness in Finland during the 1990s and early 2000s. This accentuation of economic objectives is studied at the level of national policy-making as well as at the regional level through the policies and strategies of cities and three universities in the Helsinki region. By combining the analysis of state policies, urban strategies and university activities, the study illustrates the pervasiveness of the objective of economic competitiveness and growth across these levels and sheds light on the features and contradictions of these policies on a broad scale. The thesis is composed of five research articles and a summary article. At the level of national policies, the central focus of the thesis is on the growing role of science and technology policy as a state means to promote structural economic change and its transformation towards a broader, yet ambivalent concept of innovation policy. This shift brings forward a tension between an increasing emphasis on economic aspects – innovations and competitiveness – as well as the expanding scope of issues across a wide range of policy sectors that are being subsumed under this market- and economy oriented framework. Related to science and technology policy, attention is paid to adjustments in university policy in which there has been increasing pressure for efficiency, rationalisation and commercialisation of academic activities. Furthermore, political efforts to build an information society through the application of information and communication technologies are analysed with particular attention to the balance between economic and social objectives. Finally, changes in state regional policy priorities and the tendency towards competitiveness are addressed. At the regional level, the focus of the thesis is on the policies of the cities in Finland’s capital region as well as strategies of three universities operating in the region, namely the University of Helsinki, Helsinki University of technology and Helsinki School of Economics. As regards the urban level, the main focus is on the changes and characteristics of the urban economic development policy of the City of Helsinki. With respect to the universities, the thesis examines their attempts to commercialise research and thus bring academic research closer to economic interests, and pays particular attention to the contradictions of commercialisation. Related to the universities, the activities of three intermediary organisations that the universities have established in order to increase cooperation with industry are analysed. These organisations are the Helsinki Science Park, Otaniemi International Innovation Centre and LTT Research Ltd. The summary article provides a synthesis of the material presented in the five original articles and relates the results of the articles to a broader discussion concerning the emergence of competition states and entrepreneurial cities and regions. The main points of reference are Bob Jessop’s and Neil Brenner’s theses on state and urban-regional restructuring. The empirical results and considerations from Finland and the Helsinki region are used to comment on, specify and criticise specific parts of the two theses.

A Success Story or a Failure? : Representing the European Integration in the Curricula and Textbooks of Five Countries

The economic, political and social face of Europe has been changing rapidly in the past decades. These changes are unique in the history of Europe, but not without challenges for the nation states. The support for the European integration varies among the countries. In order to understand why certain developments or changes are perceived as threatening or as desired by different member countries, we must consider the social representations of the European integration on the national level: how the EU is represented to its citizens in media and in educational systems, particularly in the curricula and textbooks. The current study is concerned with the social representations of the European integration in the curricula and school textbooks in five European countries: France, Britain, Germany, Finland and Sweden. Besides that, the first volume of the common Franco-German history textbook was analyzed, since it has been seen as a model for a common European history textbook. As the collective representations, values and identities are dominantly mediated and imposed through media and educational systems, the national curricula and textbooks make an interesting starting point for the study of the European integration and of national and European identities. The social representations theory provides a comprehensive framework for the study of the European integration. By analyzing the curricula and history and civics textbooks of major educational publishers, the study aimed to demonstrate what is written on the European integration and how it is portrayed how the European integration is understood, made familiar and concretized in the educational context in the five European countries. To grasp the phenomenon of the European integration in the textbooks in its entirety, it was investigated from various perspectives. The two analysis methods of content analysis, the automatic analysis with ALCESTE and a more qualitative theory-driven content analysis, were carried out to give a more vivid and multifaceted picture of the object of the research. The analysis of the text was complemented with the analysis of visual material. Drawing on quantitative and qualitative methods, the contents, processes, visual images, transformations and structures of the social representations of European integration, as well as the communicative styles of the textbooks were examined. This study showed the divergent social representations of the European integration, anchored in the nation states, in the five member countries of the European Union. The social representations were constructed around different central core elements: French Europe in the French textbooks, Ambivalent Europe in the British textbooks, Influential and Unifying EU in the German textbooks, Enabling and Threatening EU in the Finnish textbooks, Sceptical EU in the Swedish textbooks and EU as a World Model in the Franco-German textbook. Some elements of the representations were shared by all countries such as peace and economic aspects of the European cooperation, whereas other elements of representations were found more frequently in some countries than in others, such as ideological, threatening or social components of the phenomenon European integration. The study also demonstrated the linkage between social representations of the EU and national and European identities. The findings of this study are applicable to the study of the European integration, to the study of education, as well as to the social representation theory.

Biomass to liquid transportation fuel via Fischer Tropsch synthesis - Technology review and current scenario

Current global energy scenario and the environmental deterioration aspect motivates substituting fossil fuel with a renewable energy resource - especially transport fuel. This paper reviews the current status of trending biomass to liquid (BTL) conversion processes and focuses on the technological developments in Fischer Tropsch (FT) process. FT catalysts in use, and recent understanding of FT kinetics are explored. Liquid fuels produced via FT process from biomass derived syngas promises an attractive, clean, carbon neutral and sustainable energy source for the transportation sector. Performance of the FT process with various catalysts, operating conditions and its influence on the FT products are also presented. Experience from large scale commercial installations of FT plants, primarily utilizing coal based gasifiers, are discussed. Though biomass gasification plants exist for power generation via gas engines with power output of about 2 MWe; there are only a few equivalent sized FT plants for biomass derived syngas. This paper discusses the recent developments in conversion of biomass to liquid (BTL) transportation fuels via FT reaction and worldwide attempts to commercialize this process. All the data presented and analysed here have been consolidated from research experiences at laboratory scale as well as from industrial systems. Economic aspects of BTL are reviewed and compared.

The precautionary approach and the management of the European eel (Anguilla anguilla) – critical remarks

Recruitment and commercial catches of European eel have been in decline since the late 1970s. So far, the reasons are not well understood. A range of potential natural and anthropogenic reasons have been discussed, but the relative importance of the factors is unknown. As a consequence of the decline in recruitment an urgent need for protective management measures was concluded. The main approach is to restrict the fishery on eel, in particular with reference to the precautionary approach. However, in view of the lack of knowledge on the factors responsible for the recruitment decline and by considering that many yellow and silver eel stocks in freshwaters depend on restocking by the fishery, such simplified conclusions are critically discussed. A concept for the sustainable management of eel has to include 1) research on the factors determining the population dynamics, in particular during the oceanic stages, 2) a stronger consideration of socio-economic aspects, and 3) intensified research on artificial reproduction and rearing of eel.

Bilboko Eraztun Berdeko ekosistemek eskaintzen dituzten zerbitzuen azterketa eta erabiltzaileen pertzepzioa

[EUS] Hiriko ekosistemak garrantzi handiko gune berdeak bilakatzen ari diren honetan, geroz eta gehiago dira eremu naturalen kudeaketarako estrategiak garatzeko biodibertsitatearen eta ekosistemen zerbitzuen balioa kontuan hartu behar dela uste dutenak. Ekosistemen zerbitzuen (gizakiak ekosistematik eskuratzen dituen onurak) kudeaketa jasangarria garatzeko, zerbitzuon eskaintza eta eskaria kontuan hartzen dituzten aspektu biofisiko, sozio-kultural eta ekonomikoak ezagutzea beharrezkoa da. Ikerketa honetan, hiritarrek Bilboko Eraztun Berdeko ekosistemek eskaintzen dituzten zerbitzuen inguruan duten pertzepzioa ezagutu nahi da, jendeak eskaintzen diren zerbitzu guztiak hautematen dituen jakiteko. Horretarako, ikertutako arean ekosistemen hiru zerbitzu kartografiatu dira (aspektu biofisikoa) eta 111 pertsona inkestatu dira euren iritzia ezagutzeko (aspektu sozio-kultural eta ekonomikoa). Hala, ikusi da hiritarrek naturak ongizaterako duen garrantzia ezagutzen dutela, nahiz eta ekosistemen zerbitzuen kontzeptua ez ezagutu. Dena dela, ekosistemak egoera onean mantentzeko prest daude, bereziki garrantzitsuak iruditzen baitzaizkie erregulaziozko zerbitzuak (airearen kalitatea) eta zerbitzu kulturalak (lasaitasuna, aisia, eta naturarekin kontaktua). Beraz, emaitza hauek kontuan hartu beharko lituzkete Bilboko Eraztun Berdeko ekosistemen kudeaketaz arduratzen diren agintariek, etorkizun hurbilean zerbitzuen eskaintza eta eskariaren arteko kudeaketa orekatua garatzeko.

A tutela extrapatrimonial do nascituro no ordenamento jurídico brasileiro

Propõe-se estudo teórico com o objetivo de examinar a extensão e os limites da proteção jurídica concedida aos nascituros no ordenamento jurídico brasileiro. Há décadas a doutrina nacional se debruça acerca da exegese mais adequada do art. 4 do Código Civil de 1916, que, atualmente, corresponde ao art. 2 do Código Civil, com pequenas modificações textuais, mas sem alterar substancialmente o dispositivo. O Código Civil aparentemente optou pela atribuição da personalidade civil somente após o nascimento com vida, assegurando, contudo, os direitos do nascituro desde a concepção. O próprio Código Civil prevê expressamente direitos ao nascituro, como o direito a se beneficiar de doação e herança, o direito ao reconhecimento de paternidade e o direito à curatela. Nas últimas décadas outras leis infraconstitucionais reforçaram a proteção do nascituro, para resguardar direitos próprios do nascituro, entre eles o direito à assistência pré-natal, o direito à saúde e à integridade física e o direito aos alimentos. Não obstante, é costumeira a consciência de que o reconhecimento desses direitos pressupõe a concessão da personalidade civil desde a concepção, visto que a titularidade deles dependeria do gozo pleno da personalidade. Embora, pelo perfil do interesse, não haja óbice ao reconhecimento de situações patrimoniais, existenciais e dúplices, que podem ser titularizadas pelo nascituro, a preocupação do legislador nacional sempre se centrou nos aspectos patrimoniais. Diante da existência de situações jurídicas subjetivas merecedoras de proteção por parte do ordenamento jurídico titularizáveis pelos nascituros, pretende-se identificar e revelar os direitos extrapatrimoniais do ente por nascer como merecedores de tutela no direito brasileiro. Mediante pesquisa bibliográfica, observada a metodologia do direito civil constitucional, serão examinados os conceitos de nascituro, bem como as teorias existentes sobre os direitos que lhe são assegurados, com vista à possibilidade de proteção de seus direitos existenciais

Avaliação da eficiência do tratamento combinado de lixiviado com esgoto doméstico em estação de tratamento de esgoto.

Os lixiviados de aterros de resíduos sólidos urbanos possuem um potencial poluidor que necessita de atenção por parte das autoridades no assunto Universidade, Estado, Iniciativa Privada. Atualmente têm sido pesquisadas tecnologias para esse tratamento que sejam capazes de assimilar as variações de volume e de carga orgânica dos mesmos. O tratamento biológico combinado de lixiviados em Estações de Tratamento de Esgoto mostrase uma alternativa viável. Neste trabalho foi avaliado o tratamento combinado de lixiviado e esgoto em uma Planta Piloto de lodos-ativados, instalada na ETE de Icaraí/Niterói (RJ). O estudo foi desenvolvido com percentuais de lixiviado nas proporções de 0,5 a 2,5% em relação ao esgoto (volume/volume). Em termos de carga de DQO, os percentuais foram de 1,9 a 8,7% de carga equivalente ao lixiviado adicionado. Na Planta Piloto os resultados indicaram redução média de DQO de 73% ao longo de todo o monitoramento, sendo alcançadas remoções acima de 90%. Valores médios de DQO remanescente no efluente da planta piloto variaram de 43 a 134mg/L. Quanto às remoções médias de nitrogênio amoniacal foram alcançados valores de 80 a 97%. A redução de matéria orgânica, em termos de COD foi de 73%. Também foram monitorados reatores aeróbios em bancada de modo a avaliar possíveis interferências no desenvolvimento do lodo biológico. Foram operados reatores em regime de batelada e em regime contínuo. Os reatores não indicaram prejuízos ao lodo biológico em função do acréscimo de lixiviado para os percentuais de mistura 0,5 a 2,5% de lixiviado. Foram observadas reduções de DQO acima de 80%. As remoções de nitrogênio amoniacal foram maiores no reator operado em regime de batelada (>80%). Os resultados obtidos demonstram a viabilidade técnica do tratamento combinado e não indicaram interferência negativa no tratamento, em se tratando de redução de DQO, com o aumento da percentagem de lixiviado. Problemas na sedimentabilidade do lodo biológico foram observados ao longo de todo o período de operação da planta piloto, não havendo indicação de perda de sua qualidade em função das diferentes concentrações de lixiviado na alimentação.

O estudo prévio de impacto de vizinhança e sua exigibilidade para o exercício do direito de construir quando da criação do condomínio edilício à luz da Constituição

O presente estudo objetiva sublinhar o estudo prévio de impacto de vizinhança como instrumento de política urbana apto a conformar a autonomia privada do incorporador imobiliário no exercício do direito de construir o condomínio edilício a legalidade constitucional. O que justifica o debate é a necessidade de harmonizar,numa sociedade de risco, a liberdade de construir o condomínio edilício à proteção e não degradação do meio ambiente urbano, gerenciando os riscos e planejando a utilização e fruição dos recursos ambientais, apresentando um instrumento de política urbana que alie a livre iniciativa do incorporador imobiliário e a preservação ambiental urbana como meta. Nestes termos segue o problema do presente estudo:qual é o instrumento de política urbana que pode conformar a autonomia privada do incorporador imobiliário no exercício do direito de construir o condomínio edilício à legalidade constitucional?Para responder esta indagação buscou-se: escorçar o histórico dos aspectos jurídicos e econômicos na produção do condomínio edilício; relacionar o princípio do numerus clausus e da tipicidade nos direitos reais para distinguir o condomínio edilício como tipo de direito real; identificar o espaço para fixação do conteúdo do condomínio edilício pelo incorporador imobiliário na viabilização, instituição e constituição; sublinhar a legalidade constitucional como um método hermenêutico; identificar as premissas metodológicas da legalidade constitucional; identificar os valores constitucionais que irradiam no exercício do direito de construir o condomínio edilício na cidade; distinguir a noção contemporânea de vizinhança; sublinhar a disciplina jurídica do estudo prévio de impacto de vizinhança; e identificar os conteúdos dos fatores de investigação do estudo prévio de impacto de vizinhança, relacionando-os com a construção do condomínio edilício. A pesquisa teve um enfoque quali-quantitativo no tratamento dos dados levantados em censos e relatórios de pesquisa, segundo amostras estratificadas e de acessibilidade do universo pesquisado, com a utilização do método de procedimento descritivo, tendo como delineamento as bibliografias e documentos concernentes ao tema. Os resultados revelaram que a construção do condomínio edilício pode causar impactos na vizinhança; que o estudo prévio de impacto de vizinhança é o instrumento de política urbana necessário para conformar a autonomia privada do incorporador imobiliário, no exercício do direito de construir o condomínio edilício, a legalidade constitucional; que para exigi-lo depende de regulamentação legal municipal; e que é baixa esta regulamentação dentre os Municípios brasileiros.

Studies on the preparation of fish silage. 4. Economics of production

Economic aspects of producing liquid and dried silage from silver belly (Leiognathus splendens) in Sri Lanka are considered. A discounted cash flow analysis for the production of a dried fish silage/rice bran product suitable for use in compounded poultry feeds shows that the internal rate of return for a 10-year project would be between 34-77% and for a 5-year project between 26-73%. Thus it is concluded that the project would be extremely profitable.
