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.

The following project has been made in collaboration with, Denator AB, a biotechnology enterprise. One-dimensional electrophoreses have been used to analyze protein contents of tissue samples. Tissue samples have been either treated according to the company´s newly developed tissue treatment technique or not treated at all and comparisons between these samples have been made. In order to see differences in protein patterns between samples more clearly, a conversion method has been developed where electrophoresis gel visual patterns are used to produce curves, similar to densitometer curves.Denator AB would like to know if the proteins in their treated samples will change visibly over 48 h when incubated at room temperature. This has been investigated using the above mentioned method.

Train travel has increased in Sweden, and future increase of train transports putdemands on the already vastly exploited railroad net. The increased need of capacitycan be seen in the ongoing and planned expansions of the railway track. One part ofthe railroad infrastructure which is affected by an increase of travellers is the design ofthe station platform. Since the platform is the place where the traveller meets thetrain, dangerous situations can occur in this environment. A number of studies focuson single safety risks, albeit there is no research to show the full picture of safety inthe platform environment.This study aims to treat and put together a compilation of risks for the traveller in theplatform environment in the form of a checklist, which can be used as support inplanning and design of a safer platform environment for existing or planned platforms.The thesis has, through case studies of five ongoing projects within the NationalRailroad Administration (Banverket), interviews with train company personnel andinternational railroad administrators, identified and treated safety (and security) risksin the platform environment.The conclusion of the study is that the relations between the traveller, the physicalplatform environment and the project organisation are important to explore andexploit when designing effective safety measures.

This essay describes a single case self-study of a music composer in order to track the compositional process in real time. In the study the subject and the researcher are the same person. The study builds on previous empirical studies that have used methodological approaches such as analysis of computer-based digital data collection, verbal protocol and video observations. It deals with issues of the compositional process related to for example time consumption, number of artistic decisions, the different roles and skills of a music composer, and methods of research in the musical composition process. During three shifts the researcher worked as a music composer dealing with the issue of converting an audio sketch of a composition into a representative finished audio product.

SammanfattningSyftet med denna studie är att undersöka relationen mellan några av de engelska texter elever på grundskolan i årskurs 8 möter i sin vardag och de texter de möter i skolans engelskundervisning och vad det kan få för betydelse för undervisningen i skolan.Följande frågeställningar ligger till grund för undersökningen:? Vilka olika slags engelska texter möter elever i sin vardag?? Vilka slags texter möter de i skolans undervisning?? Vilka likheter och olikheter finns det mellan den engelska eleven möter utanför skolan med den engelska de möter i skolan?? Vilka fördelar och nackdelar finns det med att eleverna möter mycket engelska utanför skolan? ? Vilka kan konsekvenserna tänkas bli för undervisningen i engelska i skolan? Den metod jag använde mig av var en enkätundersökning med 22 elever från ?Fast Track-klass? årskurs 8 klass och sedan jämföra resultat med en undersökning som Skolverket genomfört och som heter English ? here and there and everywhere.De resultat jag kom fram till var att eleverna har väldigt mer kontakt med engelska utanför skolan än i skolan. Eleverna ser mycket ofta på engelskspråkig TV/video, kassetter/CD och film med eller utan svensk textremsa. Eleverna lyssnar på enormt mycket musik med engelska texter varje vecka. Engelska är också det dominerande språket på Internet och i dataspel vilket spelar en stor roll i ungdomarnas kultur idag..

In this thesis, the Train Power System Simulator (TPSS) has been compared and verified with the commercial simulator TracFeed® Simulation (TracFeed). The basis for the comparison was a given part of the Swedish railway system, with steel transportation trains. Primarily, emphasis was placed on running time and energy consumption in simulation results. Two transformer systems were analyzed, booster and auto transformers. The high voltage transmission line, parallel to the railroad track, was disconnected in some simulations.

In recent years, global organizations safeguarding financial stability has started to track commercial property markets. One of the reasons for this refers to the fact that commercial property constitutes a large share of bank lending. Simultaneously, bank exposures to commercial property are extensive and risky since collateral values are strongly correlated to borrowers cash flows. Since banks are viewed to play a key role for financial stability, studying the relationship is well motivated. To better understand how commercial property markets interact with financial stability, this paper develops an econometric model for studying the commercial rental market.

The aim in this thesis is to use carbon, nitrogen and sulfur isotope analysis on teeth and bone to track diet and mobility of the population as well as the individual level from the articulated and disarticulated individuals from the passage grave Frälsegården, situated in Gökhem parish in the region of Falbygden, western Sweden.50 human samples were analyzed from tooth, mandibula and femur, together with 11 faunal samples from different bone elements of local wild and domestic animals.The results fall well in line with earlier stable isotope work done on passage grave individuals from Falbygden in stable isotopes: A homogenous group with a diet which was clearly terrestrial and lived on a pretty high trophic level. It also seems that the analyzed individuals deliberately focused their food intake to the cultural and natural, megalith and limestone landscape of Falbygden, and not to its surroundings, even if the passage grave is situated in the outermost areas of the region.A small study compares the sulfur results to with earlier work done on strontium isotopes. The results show that the different methods might provide a deeper understanding in the interpretation of the methods, and therefore suggesting that further work should be done to compare the methods..

SammanfattningDenna rapport har som syfte att identifiera drivkrafter och hinder för samverkan inom och mellan företag ? samhälle ? universitet i bil- och komponenttestverksamheten i Norrbotten. Detta uppfylls genom att beskriva de olika initiativ för samverkan som i dagsläget finns inom de olika sfärerna. Med teoriverktygen trippelhelix, nätverk, inbädd-ning och utmaningar med regional samverkan, analyseras sekundärdata och kvalitativa djupintervjuer med nyckelpersoner inom de olika samverkansområdena.De olika aktörerna har skilda huvudmål i sina verksamheter, men har skapat gemensamma initiativ för samverkan på olika plan med målet att utveckla testverksamheten och regionen. De huvudsakliga drivkrafterna har identifierats som lokalbefolkningens och entreprenörernas vilja att bo kvar i glesbygd, vilket ställer krav på att utvecklas till en åretruntverksamhet.

Utvecklingen av nya vårdkedjor, s.k. ?Fast-track? eller snabbspår, sker ständigt vilket bidragit till minskade väntetider och höjd kvalitet på akutsjukvården. Med det snabbt ökande antalet snabbspår har också ambulanssjuksköterskans ansvarsområden utökats, vilket gör det viktigt att ambulanssjuksköterskan får bra stöd från organisationen och att deras tankar kring snabbspår kommer fram. Syftet med studien var att beskriva ambulanssjuksköterskans upplevelse av stress vid arbete med snabbspår.

This master thesis has been performed at Solvina in Gothenburg for Skellefteå Kraftand Vattenfall Eldistribution. The aim of it is to investigate the consequences of theinstallation of a wind power plant on the mountain Uljabuouda in the vicinity ofArjeplog. Especially the impacts on voltage and transient stability are examined.Furthermore, the amount of extra strain on the voltage regulation equipment and theneeds for increased regulation capabilities are looked into.The wind power plant is planned to be built by Skellefteå Kraft and connected to a130 kV grid owned by Vattenfall Eldistribution. The work comprehends the followingmain parts:- Theoretical studies aimed at wind turbines and power system stability issues.- Modelling of the type of wind turbines assumed to be built on Uljabuouda.- Simulations of different operation cases and analysis of the simulation results.The results from the simulations show that, as far as voltage stability and extraworkload on tap-changers are concerned, the wind power plant does not, in anysignificant manner, worsen the present conditions. The problem of overloading theline between Arvidsjaur and Vargfors is also minor.

I wrote this essay with the aim to explore, understand and get some insights into what it is that effects the possibilities to plan for ecological sustainability and make it happen. There is no clear definition of sustainable development but world top meetings and reports have developed goals and strategies. I will present some of the theory at hand but most of this essay is based on six interviews with planners at local governments from around the country. Several of the local governments are using the goals issued by the state government by putting them into their large scale plans. During the interviews some obstacles were identified, like a lack of resourses, disadvantaging powerstruktures, conflicts with marketeconomy and simply different meenings about what ecological sustainability is in practice. My method of getting information through interviews and documenting them by taking notes had, as all methods, it?s weakneses.

In the haulage business customers are constantly requesting new features. Hence thedevelopment department must constantly update their system which ultimatelyresults in a variety of versions of the system. The large number of versions creates acomplexity which often reduces product quality and extends the developmentlifecycle time.The work on the following thesis has taken place at Scania?s Fleet Managementdepartment, which develops tools for hauliers to track their vehicle fleet in real time.The purpose of this thesis was to examine how Scania can handle an increasedamount of versions of the Fleet Management System which Scania expect will be seenin the future. The investigation was conducted by preparing a number of differentscenarios that formed the basis for a discussion of what these different scenarioswould mean for different parts of Scania?s business.

Travelling by train has increased during the last decades in Sweden. This has put pressure on the existing infrastructure and has created problems with delays and cancelled departures. The railway is a complex system with mutual dependencies and high vulnerability for disruptions. The situation for the railway system in the Stockholm region is today strained. The capacity is fully used.

During the cultivation season there are a several cropping activities to carry out. At what time these activities are carried out is affecting the result and also on the economy of the crop production. As the production costs are high in potato production, it is important to keep an eye on the economy. Profitability is the most important factor in most crop production systems. If the costs are not covered, it is difficult to justify the production.
