Predicting spawning bed erosion and longevity : a case study in tributaries to river Vindelälven, northern Sweden
Timber floating operations in Scandinavia during the 19th and 20th centuries has contributed to severe negative impacts on riverine ecosystems. Increase in water velocity and lack of stream bed heterogeneity as a result of stream channelization lead to increased bed load transport. Since availability and recruitment of new suitable spawning substrate in Scandinavian watercourses is sparse, spawning habitats for salmonids has become a scarce commodity. Lately, increasingly more attention has been given to the recreation and improvement of brown trout (Salmo trutta) spawning habitats in restoration projects. While much of the research on spawning habitat has been focused on evaluation of the influence that the constructed spawning grounds have on fish populations, few studies have been conducted to evaluate the persistence of these constructions over time.
I evaluate erosion of constructed spawning beds as an effect of sediment transport attributable to water discharge.
Analysmodellen - en variation i tillämpningen?
The purpose of our essay is to examine if variation exists in the way that auditors try their independence, this so called analysis-model. We will suggest some factors that influence the way auditors practise the analysis-model. The institutional theory predicts no differencies since the normative pressure could be expected to be severe. But we found that among other things people?s qualifications, personalities and audit firm?s size and age influence the way auditors try their independence.
Den riskfyllda transporten ? Intensivvårdssjuksköterskans erfarenheter och reflektioner
Bakgrund: En intrahospital transport (IHT) är en förlängning av patientens fortsatta vård och därför en naturlig del av intensivvårdssjuksköterskans uppgifter, en uppgift som är förknippad med höga risker för patienten. Syftet: Att belysa intensivvårdssjuksköterskans erfarenheter av oförutsedda händelser i samband med IHT samt deras reflektioner på patientsäkerheten vid IHT. Metod: En pilotstudie genomfördes med en fokusgruppintervju bestående av fem intensivvårdssjuksköterskor. Insamlad data analyserades med hjälp av kvalitativ innehållsanalys med induktiv ansats. Resultat: Fokusgruppen har erfarenheter av oförutsedda händelser som är av både system- och patientrelaterande art.

Hållbara transporter i Hemavan Tärnaby och Åre : En innehållsanalys av 13 Svenska turistaktörers hemsidor
Transport is an important aspect to take account in efforts to achieve sustainable tourism development. If we do not change our behavior regarding travel, the consequences will be significant for the environment. This study examines the various transport operators on the two Swedish ski resorts if their websites and marketing are different from each other in the mode selection. The destinations are Åre and Hemavan Tärnaby. They studied modes are two Swedish airlines, two train companies, three bus companies and three taxi companies.These corporate websites are studied with a content analysis in which the results of the keywords that have been developed are scored according to different categories.
Icke-linjära modelleringsteknikerav förspänd betongkonstruktion : Reaktorinneslutningen på Forsmark 3
A new material model, for the FE-program ADINA, has been verified against twoexperiments. One unreinforced concrete beam and one reinforced concrete beam.The model, DF-concrete, has the possibility to estimate true concrete. However theresults indicate that in order to be sure that the estimations are true, there ought tobe data from the true concrete to verify against.Two FE-models have simulated the behavior of a ring-shaped part of the nuclearcontainment vessel. The results from the first, frictionless, model agree with similarsimulations and hand calculations for high pressures in the containment vessel. Thesimulations of the nuclear containment vessel show cracking in the concrete after10-11 bars of over pressurization.
Framtagande av en investerings- beslutsmodell för mindre tjänsteföretag
Problems:How would a decision model that takes into account more aspects and dimensions than just the financial aspect look for smaller service compa-nies? What aspects are important to consider in such a decision model?Purpose:The purpose of this master thesis is to develop a decision model based on previous research, to improve decision making in smaller service com-panies ? by considering perspectives that traditional investment calcula-tions ignore.Method:The study was qualitative and was based on both primary and secondary data. As data collection method for the development of the model we used literature search on previous research. The study?s primary data consisted of responses from five smaller service companies.
En geopolitisk återkomst : Kultur, ekonomi och territoriell konstruktion i samband med inomstatliga konflikter
Through geopolitical theory this thesis explores how conflicts within states can be read and understood according to an analytical model determining one or several possible causes for the conflict. The model is created by the author and reflects geopolitical theory by giving three possible explanations to an intrastate conflict: culture, economy or territorial construction. The aim of the thesis is testing this model on two selectively chosen case studies ? i.e. two intrastate conflicts ? namely: the upcoming referendum in Scotland and the terror attack at Tiananmen Square in China.
Project Inti : Produktutveckling av en solugn
In this report the two authors, and project contributors alike, describe their work withdeveloping a solar cooker intended for usage in the developing countries of the world.Specifically, the work aims at developing a new, solar heat driven cooking device, possiblybased upon the current product. This should, in comparison to the current product, be lighter,easier to transport and to produce. Also, the new product?s production mustn?t be more costlythan today and the included materials and components must be obtainable from within theBolivian national borders where the product is currently produced. During the project, certainadvantages with a more efficient, and, above all, a more moderately priced product, werediscovered.
Metodikmodell för styrning vid inköp
The work with this report has been focused on developing a methodology model for control at purchase. The methodology model covers parts classification, dispatching systems, batch shaping and more. The aim with the methodology model is that it will be used as an aid for a cost effective material planning to increase the value for customer.The work covers also a description of the present situation and the purchase process at Company X. Six parts have been applied, two from each class (A, B and C), in the methodology/model. The parts that have been applied are included in the flow between Company X and their supplier Company Y.Data have been collected trough literature studies, interviews and the company?s business system.

På väg mot ett hållbart resande? : En fallstudie kring den lokala kollektivtrafiken i Umeå tätort
Sustainability and the traffics impact on the environment have become increasingly central within spatial planning. For many years, planning has been focusing on building new roads - this has resulted in increased use of automobiles, which many believe is unsustainable in the longer term. Therefore, authorities at national, regional and local level want to increase the use of alternative transport modes ? such as walking, cycling and traveling by bus.The thesis intends to study if the Municipality of Umeå?s policies for sustainable development have led to an increased use of public transportation. The use of public transport in Umeå is also compared with developments at national level, in order to see if there are differences in the level and trend.
Att ta cykeln till arbetet : en studie av Stockholms satsning på cykelpendlare i jämförelse med Köpenhamn och London
The bicycle is an individual means of transport. Many people prefer to cycle over short distances and in congested areas rather than take travel by car or public transport. This is a study of the use of bicycle as an option for commuting to work. It is a comparison between three cities: Stockholm, Copenhagen and London. The comparison is focused on solutions that benefit commuter cyclist and performed by studying cycle policies and other related documents.
Flödeslogistik vid Laponia Hotel
The aim of this report is to analyse the logistics of a medium sized restaurant and give an overall solution for improvements on the restaurant's logistics. The restaurant of interest belongs to Laponia Hotel and is located in Arvidsjaur, Sweden. Investments for over 100.000 Euros are planned for the hotel, which includes a reconstruction of the restaurant. The details on how the restaurant will be reconstructed are not yet known. I therefore chose to analyse the problemin general terms and find a solution that is focused on the logistic system itself rather than its layout.
