During the timber floating era, most of Sweden?s watercourses were altered. This decreased the amount of available spawning habitats for salmonids, and hence had a negative effect on the riverine brown trout (Salmo trutta) populations. Reconstruction of spawning grounds is today a common measure in restoration of altered streams in Sweden. However, very little evaluation of the effectiveness of these reconstructed spawning grounds exists.

This thesis project is based on a business idea where users can design their own t-shirt online. The project shows the first step in the development process where a prototype for a user interface is created and evaluated.The purpose of this thesis project is to answer the following question:How does one develop a user interface for t-shirt design with consideration to interaction design theories?In order to answer this question the design process began with scheduling the work at hand. The first step was to build a conceptual model based on specifications made prior to this project. This conceptual model became the foundation for the physical design.A high fidelity prototype was created using Macromedia Flash and Actionscript 2.0.

Large-scale land investments is not a new phenomenon, but increasing prices on food and agrofuels have inflated prices on land and has led to an enhanced interest in landinvestments from a range of different actors. The ProSavana project in the Nacala corridor in the Nampula province, northern Mozambique is a large-scale land investment with the purpose of establishing intensive commercial agriculture and is planned to be implemented this year (2013). The project is financed by Brazil and Japan in collaboration with the government of Mozambique. It is not quite clear how large-scale land investments affect the areas they are implemented in and how they can affect the possibilities for sustainable development in these areas. Both opportunities and problems can be observed within the social, economic and ecological dimensions of sustainable development.

In this thesis a transport system is sought after thatif realised in the city of Uppsala could provide bothwell-being to all its inhabitants and sustainability,here jointly refered to as liveability. It is found thatthe car dominated transport system that is inoperation today provides two fundamental values,namely accessibility in both time and space, whichsets it apart from other transport solutions. Thesetwo values are of immense importance for theliveability in our modern world. On the other handthe car dominated system decreases the liveabilityof Uppsala in several different ways. Some of theseproblems, it is argued, could be solved within thecar system, through the adoption of moreenvironmentally friendly cars etc., but otherproblems are inherent in the car system and willremain no matter what changes are made.

Syftet med studien var att undersöka självförtroende och kroppsbild hos datorspelare, styrketränare och en kontrollgrupp. En webbenkät med manliga medlemmar på dator- och idrottsrelaterade internetforum genomfördes. Kontrollgruppen var medlemmar på dessa forum som varken styrketränade eller spelade datorspel. Skalorna Social physique anxiety scale, Rosenberg self-esteem scale och Drive for muscularity scale administrerades. Resultatet visar att grupperna inte var signifikant skilda åt gällande social fysisk ångest eller självförtroende.

Because of increasing demand of power on Malmbanan the capacity of the existing wires which supply the trains must be increased. This increases the stress on the existing poles and for this reason the system for supplying the loads along the railway is to be removed from the poles and be replaced by some other system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs.In this thesis the following tasks have been performed:? Gathering of data? Description of basic theory? Loadow and fault current calculations of the system with MATLAB? Life Cycle Cost estimate of the system? Analysis and conclusions from the resultsThe results show that the new system can be an alternative to replace today's system. The simulations and calculations show that the voltage drop is at an acceptable level and that the fault currents are large enough to supply a safe disconnection if a fault occurs at the far end of the system..

This study aims to investigate how federations manage to balance the economies of scale through collaboration and autonomy. This is done through a case study on Länsförsäkringar. The lack of modern research on federations makes the federative structure an interesting field of study. Previous research has shown a general perception that an increased pressure on efficiency and economies of scale creates a stronger common unit that eventually creates an imbalance in the federation. It is therefore interesting to look at the balance, which exists between the member units and the common unit of a federation.

Quality assurance of construction projects and create effective ways of working, is intoday's pressed position, major objectives for building contractor companies. This thesis is an attempt to see if it is possible to achieve these goals with the new modern tool iPad.The author of this thesis has during the latter half of his one year practice work in Uppsala for the Swedish building construction company NCC Construction Sverige AB, conducted a study on the possibility of using the iPad on an construction site. This has been done with active field studies in which applications have been tested and also the supervisors receptive. The usability of the iPad has always been in focus since it is important that the applications are easy to use and easy to learn.The results of the work, as presented in this report, points at opportunities in efficiency if the iPad is introduced and used on construction site. There are many useful applications for the iPad, and with a system that can handle the synchronization between the iPad and the computer, the workflow will be streamlined significantly..

In everyday life we perform motor behaviours that have no apparent instrumental function. Are these correlated to sensation seeking and do they differ depending on what situations we are in? University students in Örebro (N=108), participated in the study. The participants were asked to fill out a double questionnaire containing the sensation seeking scale and another one for measuring non-productive motor behaviours. The non-productive motor behaviours were not correlated to the sensation seeking scale.

This essay describes and compares the extensive reindeer management to the more intensive, but grazing based, sheep management system in Sweden. Differences and similarities between the two production systems will be investigated by elucidating the economy, land use and possibilities to influence production and economy through breeding, feeding and product development. The reindeer management area covers the northern part of Sweden whilst the sheep management is dispersed over the country. Both reindeer and sheep are ruminants and have relatively high demands on the quality and digestibility of the feed however reindeers graze on mountain-and forest lands whilst sheep often graze inaccessible areas or cultivated grasslands. Selection intensity is generally lower in the reindeer management compared to the intensity in sheep breeding.

The management of information is a significant competitiveness in companies. Companies stored and save information every day, and it is very common to save de information in different sources. This makes de management of information complex. To mange, monitor and analyze the information, companies can use a system called Business Intelligence. BI system is an analytical system that extracts and converts data into useful information that helps employees to make informed decisions.

För ett par år sedan tog utvecklingen och fokuseringen kring Internet fart på allvar ute bland företag. Alla skulle ha en webbsida och anledningen till detta var ofta att konkurrenten hade en eller att man bara ville synas. Idag finns det ett antal så kallade Content Management System utvecklade för att hantera information på Internet, intranet och extranet. Det gemensamma för dessa system är att användarna skall kunna uppdatera, vidareutveckla och administrera lösningen utan någon teknisk kompetens. Syftet med den här uppsatsen var att undersöka om ett Content Management System effektiviserar uppdateringen av information, med hjälp av kategorier inom användbarhet. Användbarhet består av flera olika kategorier, dock har vi valt att begränsa oss till tre av dessa; effektivitet, syfte och tillfredsställelse. För att få djupare kunskaper inom ämnet användbarhet har vi läst böcker och artiklar, vi har även sökt information via Internet. Vi hittade information om användbarhetstest där vi fann en metod som hette utredning.

A bioslurry reactor was built for the bioremediation of TNT contaminated waste from the demilitarization industry. The field test was conducted at Vingåkersverken in Vingåker, Sweden, to see if results from laboratory studies could be repeated in a full scale reactor. The goal of the project was to optimize the reactor to such a degree that it could be used to handle the waste produced at Vingåkersverken and also that this technique could be applied for remediation of contaminated soils. Unfortunately the samples taken during the full scale field test were destroyed by the shipping company and no analysis was possible. A later attempt by the Biorex research group has also been unsuccessful to reduce the amount of TNT using the bioreactor.
