Rwanda is one of the world's developing countries located in southern sub-Saharan region in Africa; and one of its most pressing environmental concerns is its need for stable and community-managed electrical power. Micro-Hydro Power (MHP) projects have proved to be an economical and efficient alternative in the effort to power remote villages deep in the rural area.This study investigates the efficacy of community- based MHP projects in one of these villages, in Rongi sector as well as the role of public participation in these projects. The main aim of this thesis was to develop a case study for the development of BUKABA MHP as the model at the specified zone where there is a lot of small rivers and this research shall provide a real life study at the inhabiting and the enabling factors for the development of micro scale hydro in rural areas of Rwanda. This studyb employs a case study methodology, for the design, costing and determine financial viability and feasibility of the BUKABA MHP as one piloted with data collection taken on site surveys, and document reviews using RETScreen. This study use RETScreen, as the result, the maximum power output calculated was 97kW which will be used by primary and secondary schools, local administrative buildings, commercial centers, and about 100 households at the estimated total initial cost of $CAD 619,000 as it was shown by RETScreen hydro formula costing method sheet.  We recommend the Gouvernment of Rwanda to use this project as model to be implemented, even to use it in any other area where there is availability of water. But, before implementation, the bill of quantities will be prepared to enable the Gouvernment obtain the details about the final and initial cost of the concerned project.

This thesis concerns system studies of power plants wheredifferent types of fuel cells accomplish most of the energyconversion. Ever since William Grove observed the fuel cell effect inthe late 1830s fuel cells have been the subject or more or lessintense research and development. Especially in the USA theseactivities intensified during the second part of the 1950s,resulting in the development of the fuel cells used in theApollo-program. Swedish fuel cell activities started in themid-1960s, when ASEA (now ABB) ran a fuel cell projectdeveloping fuel cells to power submarines. When the then project manager, Olle Lindström, wasappointed professor of Chemical Technology at KTH, the fuelcell activities at KTH were initiated, these activities havesince then been pursued at varying levels of intensity. The fuel cell development experienced a recession during thelatter part of the 1970s and early 1980s, only to bere-vitalised during the 1990s as the full potential of theadvantages of environmental benefits and efficiency wereidentified. System studies and process simulation utilising differentcomputer software programs may be used to study the behaviourand characteristics of fuel cells and their supportsystems. Paper I describes the characteristics of a naturalgas-fuelled fuel cell power plant using alkaline fuel cells,both regarding efficiency and economics. In paper II, a benchmark study of three different types ofsimulation software is presented. Theintention was to clarifyhow the selection of software might influence the resultsobtained, and some of the associated possible pitfalls. Paper III presents a study of a fuel cell power plant wherethe primary source of energy is biomass (wood chips), which viahigh-pressure gasification and subsequent gas cleaning is madeavailable for conversion into electricity and heat by moltencarbonate fuel cells. The last paper, paper IV, presents a s system study of ahigh-temperature fuel cell system, where the primary fuel iscoal, which through gasification is converted into a gaseousform. This study was a vital part of an EU-project studying thetechnical and economical feasibility of such systems. <b>Keywords</b>: fuel cells, fuel cell systems, system studies,process simulation, system analysis, alkaline fuel cells,high-temperature fuel cells.

Det mest vanliga idag är att kostymbyxor har två sidsömmar eftersom den har en stor vikt för plaggets passforms och komfort. Om dessa inte existerar måste byxans innerbensöm inrymma all passform vilket gör det problematiskt då byxan ska sitta nära kroppen. Studien är ett samarbete med ett svenskt modeföretag som vill skapa en effektivare konfektionslösning rörande borttagningen av en figurnära kostymbyxas sidsöm.   Uppsatsen använder sig av företagets mest sålda vara för revidering, tillsammans med jämförelse av litteratur och en marknadsundersökning. Andra metoder som används i undersökningen är avprovning på intern provmodell som bedömts visuellt och via ett avprovningsprotokoll men också tabeller i form av krav- och måttlistor.   Genom att applicera mönsterkonstruktionen på tyg i olika vinklar i förhållande till tygets trådrak har olika resultat påvisats. Resultatet visar bättre passform vid en trådrak parallellt med varpriktningen. Det visar sig även finnas ett samband med materialets draperingsförmåga, det mjukare materialet i studien ger ett finare fall. Medan 45° trådrak från varpriktningen visade ett resultat som hade passformsbrister. / The most common things today is that suit pants have two side-seams because it's of great importance to achieve the desired fit and comfort of the garment. Without the side-seams, the inside leg seam would have to involve all fits, which makes it problematic considering the garment is supposed to stay tight to the body.  The study is a collaboration with a Swedish fashion company that wants to creat a more effective clothing solution for removal of a figurative suit pants side-seams.   The essay uses the company’s best-selling product for revise, along with comparing of literature and one market research. Other methods used in the survey are tests on an internal test model, assessed visually and through a test protocol, but also test charts in regard to requirements and measurements.   By applying the pattern to the fabric at different grainlines, different results have been shown. The results shows better fit at grainline parallel to the warp direction. It also turns out that there is a connection with the draping ability of the material, the softer material in the study gives a finer drape. While 45° grainline from the warp direction showed a result that had lack of fit.

abstract: It’s no secret that wetlands have dramatically declined in the arid and semiarid American West, yet the small number of wetlands that persist provide vital ecosystem services. Ciénega is a term that refers to a freshwater arid-land wetland. Today, even in areas where ciénegas are prominent they occupy less than 0.1% of the landscape. This investigation assesses the distribution of vascular plant species within and among ciénegas and address linkages between environmental factors and wetland plant communities. Specifically, I ask: 1) What is the range of variability among ciénegas, with respect to wetland area, soil organic matter, plant species richness, and species composition? 2) How is plant species richness influenced locally by soil moisture, soil salinity, and canopy cover, and regionally by elevation, flow gradient (percent slope), and temporally by season? And 3) Within ciénegas, how do soil moisture, soil salinity, and canopy cover influence plant species community composition? To answer these questions I measured environmental variables and quantified vegetation at six cienegas within the Santa Cruz Watershed in southern Arizona over one spring and two post-monsoon periods. Ciénegas are highly variable with respect to wetland area, soil organic matter, plant species richness, and species composition. Therefore, it is important to conserve the ciénega landscape as opposed to conserving a single ciénega. Plant species richness is influenced negatively by soil moisture, positively by soil salinity, elevation, and flow gradient (percent slope), and is greater during the post-monsoon season. Despite concerns about woody plant encroachment reducing biodiversity, my investigation suggests canopy cover has no significant influence on ciénega species richness. Plant species community composition is structured by water availability at all ciénegas, which is consistent with the key role water availability plays in arid and semiarid regions. Effects of canopy and salinity structuring community composition are site specific. My investigation has laid the groundwork for ciénega conservation by providing baseline information of the ecology of these unique and threatened systems. The high variability of ciénega wetlands and the rare species they harbor combined with the numerous threats against them and their isolated occurrences makes these vanishing communities high priority for conservation. / Dissertation/Thesis / Masters Thesis Plant Biology 2016

One of the most important factors for successful cultivation of tomatoes is plant nutrition, however, because of the peculiarities observed in the greenhouse, the forms of interpretation of results of analyzes of soil or foliar nutrients that are made in isolation, is shown conflicting results when using the traditional methods of recommendation. The integrated diagnosis and recommendation (DRIS) has shown satisfactory results in different cultures by examining the interaction between nutrients. In the cultivation of tomato in greenhouse studies are lacking regarding the use of DRIS in this way, this study aimed to establish DRIS norms for growing tomatoes in greenhouses, by studying some of the major nutrients and the interactions between them influencing production. Was used results of chemical analysis of sheets for the nutrients N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn in the yield of 61 greenhouses covered with plastic, with tomato crops, comprising a total area covered implanted with the tomato crop of 24,436 m2 or 2.44 ha. The greenhouses were planted with hybrids, Colibri, Pizzadoro, Max and Deborah Granadero. Samples were collected from April to December of 2010, in greenhouses of the counties of Barra do Jacare, Cambara, Joaquim Tavora, Santo Antonio da Platina and Siqueira Campos, located in the North of Paraná Pioneer. For the formation of the database were used five levels of production, 6, 7, 8, 9 and 10 kg planta-1, with the establishment of binary relationships between all the nutrients studied in all samples. With this information, calculate the mean, standard deviation and variance for each concentration of nutrients, but also for relations between them, in each sub-population. 55 relationships were maintained, which showed the highest ratio in the variance between sub-populations. We calculated the nutritional content of each nutrient and the nutrient balance index (NBI) of each production level. Defined thus the production of 8 kg plant-1 as an index to be used because it presented the best correlation between the NBI and the productions analyzed, and the DRIS norms developed using this pattern of production. In samples that were less than 6 output kg planta-1 was the marked deficiency of K and B, and P, Cu, Mn and Zn on a smaller scale and excess Mg, N and P. In the establishment of DRIS norms when compared to existing standards recommended in the study. It was observed that there were no difference for the nutrients P, K, Ca, Mg and S, the copper content was above the standards, N, Fe and Mn were below the standard and nutrients Zn and B had an amplitude differentiated between the maximum and minimum levels accepted as the norm ideals between DRIS and established standards. / O cultivo do tomateiro em ambiente protegido está presente em diversas regiões do Estado do Paraná, pois é uma opção de renda para o agricultor familiar, utilizando pequenas áreas e mão de obra familiar, além do monitoramento das condições climáticas. Um dos fatores de maior importância para sucesso do cultivo do tomateiro é a nutrição da planta, porém, devido as peculiaridades observadas no cultivo protegido, as formas de interpretação de resultados de análises de solo ou de teores foliares que são feitas por nutrientes isoladamente, tem apresentado resultados conflitantes quando são utilizados os métodos tradicionais de recomendação. O sistema integrado de diagnose e recomendação (DRIS) tem mostrado resultados satisfatórios em diversas culturas por analisar a interação entre os nutrientes. No cultivo do tomateiro em ambiente protegido faltam estudos quanto ao uso do DRIS, desta forma, o presente trabalho teve por objetivo, estabelecer normas DRIS para a cultura do tomateiro em cultivo protegido, através do estudo de alguns dos principais nutrientes e as interações entre eles que influenciam a produção. Utilizou-se resultados da análise química de folhas para os nutrientes N, P, K, Ca, Mg, S, B, Cu, Fe, Mn e Zn com as produtividades de 61 estufas com cobertura plástica, com lavouras de tomate, compreendendo uma área total coberta implantada com a cultura do tomate de 24.436 m2 ou 2,44 ha. As estufas foram cultivadas com os híbridos, Colibri, Pizzadoro, Débora Max e Granadero. As amostras foram coletadas nos meses de abril a Dezembro do ano de 2010, em estufas dos municípios de Barra do Jacaré, Cambará, Joaquim Távora, Santo Antonio da Platina e Siqueira Campos, localizados na Região Norte Pioneiro do Paraná. Para a formação do banco de dados foram utilizados cinco níveis produtivos, de 6, 7, 8, 9, e 10 kg planta-1, com o estabelecimento de todas as relações binárias entre os nutrientes estudados em todas as amostras. Com estes dados, calculou-se a média, o desvio padrão e a variância para cada concentração de nutriente, como também para as relações entre estes, em cada subpopulação. Foram mantidas 55 relações, que apresentaram a maior razão na variância entre as subpopulações. Calculou-se o índice nutricional de cada nutriente e o índice de balanço nutricional (IBN) de cada nível produtivo. Definiu-se assim a produção de 8 kg planta-1 como índice a ser usado por ser o que apresentou melhor correlação entre o IBN e as produções analisadas, sendo as normas DRIS estabelecidas utilizando este padrão de produção. Nas amostras analisadas que tiveram produção menor que 6 kg planta-1, ocorreu a deficiência acentuada de K e B, além de P, Cu, Mn e Zn em menor escala e excesso de Mg, N e P. No estabelecimento das normas DRIS quando comparados com padrões de recomendação existentes na pesquisa. Observou-se que, não ocorreram diferenciação para os nutrientes P, K, Ca, Mg e S, o Cobre apresentou teores acima dos padrões, os nutrientes N, Fe e Mn apresentaram teores abaixo do padrão e os nutrientes B e Zn apresentaram uma amplitude diferenciada entre os níveis máximo e mínimo de teores aceitos como ideais entre a norma DRIS estabelecida e os padrões existentes.
