In this scenario, agricultural activity, especially swine, had to adapt to this new market reality through the production empowerment, developing new confinement techniques where the animal density per unit increases significantly. Consequently, this higher animals concentration per production unit confirms the intensification of organic contamination in the environment. However, the sanitary treatment of this residual biomass in anaerobic digestion systems enables the transformation of this environmental liability into an economic asset, once this treatment process enables the generation of two products with economic value - biogas and biofertilizers. Although this solution is environmentally feasible, from the economic point of view it is not always possible due to the costs of biomass treatment with energy purposes. Faced with this problem, an arrangement that demonstrates economically viable is the implementation of agricultural energy cooperatives, once this system allows scaling up the biogas production and enables the diversification of the use of this renewable energy source. In this context, this study aims, through a technical and economic feasibility analysis, identify the best scenario to implement agricultural cooperatives, focused on the residual biomass logistics and on the biogas transportation through pipelines. The methodology proposed in the work involving the municipality Entre Rios do Oeste (PR) has shown that the best scenario to produce biogas for energy purposes is the decentralized generation one, once the analyzed arrangements show a 9 years payback for electricity, 10 years for thermal energy and 7 years for vehicle biomethane, while in the biogas production centralized scenario the payback is 15 years for electricity, 10 years for vehicle biomethane, and there no payback for thermal energy arrangements. In addition, decentralized generation has lower operating costs and there is no legal restrictions on its operation. Keywords: Feasibility / O aumento acentuado da população nas últimas décadas resultou no crescimento acelerado da demanda de produção de alimentos. Diante deste cenário, a atividade agropecuária, e em especial a suinocultura, teve que se adaptar a essa nova realidade de mercado por meio da potencialização da produção a partir do desenvolvimento de novas técnicas de confinamento, onde a densidade de animais por unidade de produção aumenta significativamente. Em consequência, esta maior concentração de animais por unidade produtiva corrobora para intensificação da contaminação orgânica do meio ambiente. Todavia, o tratamento sanitário desta biomassa residual em sistemas de biodigestão anaeróbia possibilita a transformação desse passivo ambiental em um ativo econômico, uma vez que este processo de tratamento possibilita a geração de dois produtos com valor econômico - biogás e biofertilizante. Embora esta solução seja ambientalmente viável, do ponto de vista econômico nem sempre é possível, devido aos custos do tratamento desta biomassa, com fins de aproveitamento energético. Diante desta problemática, um arranjo que se demonstra viável economicamente é a implantação de condomínios de agroenergia, uma vez que este sistema possibilita o ganho de escala na produção de biogás e possibilita a diversificação do uso desta fonte renovável de energia. Neste contexto, o presente trabalho buscou, por meio de um estudo de viabilidade técnica e econômica, identificar qual o melhor cenário para formação de condomínios de agroenergia, trabalhando a logística da biomassa residual e o transporte de biogás por meio de dutos. A aplicação da metodologia proposta no trabalho para o município de Entre Rios do Oeste (PR) demonstrou que o melhor cenário para produção de biogás com fins energéticos é a produção descentralizada, visto que os arranjos analisados demonstram um Payback descontado de 9 anos para energia elétrica, 10 anos para energia térmica e 7 para biometano veicular, enquanto no cenário de geração de biogás centralizada Payback descontado é de 15 anos para energia elétrica, 10 anos para biometano veicular e não recupera no arranjo de energia térmica. Além disso, a geração descentralizada apresenta menores custos operacionais e não possui restrições legais para sua operacionalização.

The tendency to use renewable energy resources has grown continuouslyover the past few decades, be it due to fear over warnings of globalwarming or because of the depletion and short life of fossil fuels or evenas a result of the interest which has developed among researchers doingscientific research into it. This work can be considered as joining any ofthese groups with an objective of giving electric light to the poorpopulation living in one of the poorest nations in the world.The aim of the work is to investigate supplying electric energy fromsolar-wind hybrid resources to remotely located communities detachedfrom the main grid line in Ethiopia. The communities in mind are one oftwo types; the first is the majority of the poor population residing in thecountryside; and the other is people relocated by the Government fromthe over used and dry regions to relatively productive and fertile ones inline with the long-term poverty reduction plan.The work was begun by investigating wind energy and solar energypotentials at four geographically different locations in Ethiopia bycompiling data from different sources and analyzing it using a softwaretool. The locations are Addis Ababa (09:02N, 038:42E), Mekele (13:33N,39:30E), Nazret (08:32N, 039:22E), and Debrezeit (8:44N, 39:02E).The results related to wind energy potential are given in terms of themonthly Average wind speed, the wind speed probability densityfunction (PDF), the wind speed cumulative density function (CDF), thewind speed duration curve (DC), and power density plots for all fourselected sites. According to the results obtained through the analysis, thewind energy potential, even if it is not exceptional, is irrefutably highenough to be exploited for generating electric energy.The solar energy potential, based on sunshine duration data collectedover a period of 7 - 11 years and radiation data obtained from differentsources, has been calculated using regression coefficients specific to thesites in question. Based on the sunshine duration data, the monthlyaverage daily sunshine amount for each of the places has also beencomputed and given in a form of plot. Through additional work on theresults of the calculations, the solar energy potential has been given inthe form of solar radiation plots for each of the selected sites. Asexpected, the results indicated an abundance of solar energy potential.It is based on the promising findings of these two energy resourcepotentials, wind and solar, that the feasibility study for a standalonesolar-wind hybrid energy supply system has proceeded, targeting thecommunity mentioned earlier. The hybrid system consisted of Windturbine, Photovoltaic panel, diesel generator and a bank of batteries, witha power conditioning converter included in the system.The hybrid standalone supply system is intended to provide electricity toa model community of 200 families with five to six family members ineach. The community is equipped with a primary load, a deferrable load,a community school and a health post. An electric load which includeslighting, water pumping, a radio receiver, and some clinical equipmenthas been suggested. Hybrid Optimization Model for ElectricRenewables, HOMER, software has been used for the analysis. Theaverage wind speed and average solar radiation calculated from the datafor all of the selected sites has been used to input into the software.The hybrid system design is approached in three different ways. The firstapproach is to include within the hybrid system those components whichare locally available, without giving special attention to their efficienciesand proceed with the design work. The second approach is tothoroughly search the market for the best and most efficienttechnological products and to select the best components for theanalysis. A third approach considered in an attempt of cost minimizationis to see if a self-contained type of design can be a better solution. Whatthis means is every household will have its own supply system that mayconsist of any combination of PV and wind turbine including converter,battery and charge controller.After running the simulations, lists of power supply systems have beengenerated, sorted according to their net present cost. Sensitivity variables,such as range of wind speeds, range of radiation levels and diesel pricehave been defined as inputs into the software and the optimizationprocess has been carried out repeatedly for the sensitivity variables andthe results have been refined accordingly. / QC 20100623

Although there are some carbon capture and storage (CCS-CO2 sequestration) projects in all over the world, feasibility problems exist due to the high economical issues. The aim of this study is to evaluate the feasibility of a potential CCS project where the source of CO2 is Afsin Elbistan Thermal Power Plant. Selection of candidate sites in the vicinity of Diyarbakir, Batman and Adiyaman regions depends on sequestration criteria. According to sequestration criteria, CCS can be applied to &Ccedil / aylarbasi mature oil field, Midyat saline aquifer and Dodan CO2 gas field. Disposing of CO2 from the source of Afsin Elbistan Thermal Power Plant is analyzed by pipeline and tanker. CO2 capturing technologies are determined from published literature. CO2 transportation can be applied by pipeline or tanker. CO2 transportation cost by pipeline and tanker are compared. It has been calculated that, transportation by pipeline is more economical compared to tanker transportation. It is further found that the number of boosting pump stations, the length of the pipeline and CO2 mass flow rate are the issues that alter the economical aspect in the pipeline transportation. The transportation costs by tankers depend on fuel cost, distance, tanker storage capacity, pin-up cost and CO2 storage facilities. The final part of CCS project is injection and storage of CO2 to the candidate areas. Reservoir parameters which are reservoir temperature, viscosity, permeability, reservoir pressure, reservoir thickness, CO2 density mass flow rate and injection pipe diameter determine the number and cost of the injection wells.

Introduction: Breastfeeding offers the substance exposed mother and child potential short and long-term health benefits, with breast milk shown to alleviate the severity of Neonatal Abstinence Syndrome. Substance dependent women, however, have limited success establishing breastfeeding with physical, psychological and institutional factors cited as barriers. This study aimed to develop and test the feasibility of an evidence informed and theory based intervention to support continued breastfeeding for this group. Methods: The research was a two-phase feasibility study. Phase 1 informed intervention development using a mixed methodology approach which included (a) a comprehensive systematic literature review of breastfeeding support for women from disadvantaged groups (b) expert advisory group recommendations and (c) ‘think aloud’ verbal protocols with opioid dependent women. Phase 2 underpinned the evidence with the theoretical constructs of behaviour change, prior to testing the acceptability and implementation fidelity of the intervention in a feasibility study with an embedded small-scale randomised controlled trial. Results: Phase 1 identified the barriers to breastfeeding continuation as low maternal self-efficacy; neonatal feeding difficulties associated with withdrawal and unsupportive healthcare practices. Evidence and theory synthesis resulted in an integrated breastfeeding support model founded on practical, informational, psychological, person-centred and environmental components. Phase 2 demonstrated that the intervention was feasible to implement and acceptable to participants. The randomised controlled trial reported higher rates of continued breastfeeding and a greater level of maternal confidence in breastfeeding ability in the intervention group compared to the control group. Breastfed infants were less likely to require pharmacological management and had corresponding shorter durations of hospitalisation than formula fed infants. Conclusion: The research provided an original contribution to the development of a complex healthcare intervention which is meaningful to both existing research and clinical practice. The findings highlighted the potential of the intervention to support breastfeeding for the substance exposed mother and baby, which has wide ranging implications for the improved health and social equalities of this group.

O elevado consumo energético de edificações para o seu condicionamento térmico já é um dos maiores impactos ambientais da construção civil nos países desenvolvidos e, progressivamente, vem se tornando uma preocupação também nos países em desenvolvimento. Uma alternativa renovável relativamente recente, tanto para aquecimento como para resfriamento, são as bombas de calor geotérmicas (ground source heat pumps, GSHPs), que se valem da inércia térmica do solo para reduzir significativamente a demanda energética em relação ao ar. Apesar do seu grande potencial em reduzir o consumo de energia e as emissões de carbono, esta tecnologia ainda é quase inexistente na América Latina, não somente devido à falta de conhecimento ao seu respeito, mas também pela incerteza quanto à sua viabilidade frente a um custo inicial mais elevado. Embora existam muitas pesquisas sobre o funcionamento de GSHPs, grande parte do conhecimento prático quanto ao projeto, desempenho e viabilidade é baseada na experiência dos primeiros países onde a tecnologia começou a se tornar popular, e não pode ser assumida automaticamente como válida em outras situações sem uma avaliação prévia Estudos anteriores apontaram que o retorno econômico de GSHPs tende a ser maior em climas mais frios, enquanto a eficiência tende a ser maior em climas mais amenos, mas com sazonalidade. Por apresentar um bom balanço destas características, o Estado do Rio Grande do Sul apresenta potencial para um desempenho elevado de GSHPs. O objetivo deste trabalho é estimar os níveis de eficiência que esta tecnologia pode atingir em uma cidade de referência no Estado, assim como seu retorno econômico frente a ASHPs (air source heat pumps, ou seja, aparelhos de ar condicionado, ou A/C), seus limitantes e as dificuldades de projeto. Uma edificação unifamiliar residencial em Porto Alegre, projetada especialmente para estudos de sustentabilidade, foi utilizada como caso de estudo para o projeto conceitual completo de um GSHP vertical, um GSHP horizontal e um ASHP. Foram estimadas a demanda de energia e os custos de operação e de implantação para determinadas condições, que foram comparadas em um estudo de viabilidade econômica. Após, os resultados foram extrapolados por uma análise de sensitividade para condições mais genéricas de consumo. Através dos cálculos, observou-se que a tecnologia de GSHPs atingiu o dobro da eficiência dos A/C mais eficientes disponíveis para o caso de estudo. Economicamente, a tecnologia também se mostrou viável, e foram estimados limitantes econômicos a esta viabilidade. Por fim, o processo de projeto desenvolvido pode servir de auxílio a novos projetistas na área. / The high energy consumption in buildings for their thermal conditioning is already one of the greatest environmental impacts of civil construction in developed countries and, progressively, is also becoming a concern in the developing countries. A relatively recent renewable alternative, as much for heating as for cooling, are the ground source heat pumps, GSHPs, which take advantage of the thermal inertia of the ground to significantly decrease the energy demand comparing to air as a source. In spite of their huge potential for decreasing energy comsumption and carbon emissions, this technology is still almost inexistent in Latin America, due not only to lack of awareness, but mainly to uncertainties about their feasibility because of their higher investment cost. Although there are many researches about the characteristics and operation of GSHPs, great part of the practical knowledge as to the design, performance and feasibility is based in the experience from the first countries where the technology spreaded, and cannot be automatically assumed as valid without a previous evaluation. Former studies indicated that the economic profit of GSHPs tends to be higher in colder climates, while the efficiency tends to be higher in milder, but still seasonal climates. For presenting a good balance among these factors, the Rio Grande do Sul State shows potential for a high performance of GSHPs The objective of this work is to estimate the efficiency levels that can be reached by this technology in a reference city in the State, as its financial feedback compared to ASHPs (air source heat pumps, the traditional air conditioners, or A/C), its limitations and the design difficulties. A residential single-family building in Porto Alegre, specifically designed for sustainability studies, was used as case study for the complete conceptual design of a vertical GSHP, a horizontal GSHP and an ASHP. The energy demand and operation and installation costs for specific conditions were estimated and compared in a economic feasibility study. After, the results were extrapolated through a sensitivity analysis for more generic situations of consumption. Through the calculations, it was observed that the technology achieved twice the efficiency of the most efficient A/C available for the case study. Economically, the technology showed itself viable, and economic limitations were also estimated. At last, the developed design process can also serve as aid to new designers in the field.

There is no standard format for posting blog entries, which results in many different web feed formats and APIs being used. This thesis work addresses the problem by determining the feasibility of the development of a plug-in based architecture, used in a mobile blogging application compatible with multiple service providers. During the study, a definition of what a feasible architecture would be was made based on requirements set by the stakeholders. Six models that complied with this definition were designed and compared. One of them was selected for prototyping. The prototyping phase was intended to test if the architecture could be implemented in a mobile environment. The study revealed that it is feasible to develop a plug-in based architecture to solve the problem, although with some limitations due to the dependency of libraries for streaming XML transformations not yet implemented in J2ME. / Det finns inget standardformat för att posta ett blogginlägg, vilket resulterar i att många olika web feed-format och APIer används. Det här examensarbetet angriper problemet genom att undersöka om det är genomförbart att utveckla en plug-inbaserad arkitektur för en applikation till mobiltelefoner, som är kompatibel med flera olika bloggtjänster. Under studiens gång definierade vi vad termen genomförbart skulle innebära, baserat på krav från olika intressenter. Sex modeller som uppfyllde definitionen utvecklades och jämfördes. En av dessa valdes ut för att användas som grund för en prototyp. Prototypfasen avsåg att bevisa om arkitekturen kunde implementeras i en mobil miljö. Studien visade att det är genomförbart att utveckla en plug-inbaserad arkitektur för att lösa problemet, dock med några begränsningar på grund av beroende av bibliotek för strömmande XMLtransformationer som ännu inte implementerats i J2ME.

Background. Stepped care is widely implemented as a means to organise depression treatment. However, it is unclear how this system and the system it was designed to replace – long-term intensive psychotherapy for all – compare. Aim. To further the development and evaluation of stepped care. Specifically, assess the clinical effectiveness of stepped care and prepare for a fully-powered evaluation of stepped care vs. high-intensity psychotherapy alone for depressed adults. Design. A systematic review and mixed methods feasibility study encompassing a pilot randomised controlled trial and semi-structured interviews. Results of the systematic review. Fourteen randomised controlled trials involving 4580 participants were included. Relative to controls, there was significantly greater improvement in depression for adults treated with stepped care (d=0.34 at six months; 95% CI 0.20 to 0.48). The quality of included studies was good and there was little evidence of publication bias. All comparisons were with usual care. Results of the feasibility study. 66 patients were recruited to the pilot trial. The recruitment rate was 2.9% and follow-up data was obtained from 90.9% of participants. A third of stepped care patients stepped up to high-intensity therapy. Patients improved in both groups: the mean reduction in depressive symptoms was 13.4 in the stepped care group and 13.6 in the high-intensity therapy alone group. Recruitment methods were appropriate to patients and therapists but only somewhat appropriate to IAPT staff. Although the stepped care intervention was broadly acceptable to therapists, patient experience varied and some patients who demonstrated a low level of self-efficacy declined any therapy or dropped out of treatment. Conclusions. The effectiveness of stepped care compared with long-term intensive psychological therapy for all has not yet been established. A fully-powered trial of stepped care vs. high-intensity therapy alone is feasible although pilot trial methods and procedures should be modified to improve recruitment and acceptability.
