Antalet flygresor har ökat markant i världen de senaste decennierna. Detta har medfört en ökning av flygets koldioxidutsläpp som därmed har gett en ökad påverkan på klimatet. Forskning angående människors syn på och uppfattning om flyget är relativt ny och forskning rörande ämnet är mer förekommande idag än för ett decennium sedan. Tidigare undersökningar är dock i stort sett eniga om att människor, både miljömedvetna och icke-miljömedvetna personer, inte tänker ändra på sina flygvanor och flyga mindre på grund av flygets klimatpåverkan. Denna studie undersöker klimatengagerade personers flygvanor och vad de har för syn på flyget och flygets påverkan på klimatet.

Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats. The mapping included 61 km of various stream sections along the river length of 269 km. The total area of stream habitats was estimated to 647 ha of which 396 ha (61%) were considered as either potential or optimal juvenile nursery habitats. The area of these two habitat classes were used to estimate the smolt production in the river by using electro fishing densities of juveniles (0+ per 100 m2).

Most of today?s concrete structures that are built on site are mainly constructed in a traditional fashion with a lot of artisanal operations. One step towards industrializing the in-situ construction of concrete is to use prefabricated reinforcement. Through this method there can be a lot of savings when each bar doesn?t have to be placed and fixed separately on site.

The increase of complexity in embedded programming is forcing the development of higher level programminglanguages. These languages not only consist of traditional text based programming but also with graphical programminglanguages such as the programming language G from LabVIEW which is developed by National Instruments and havebeen around since the mid eighties. However since 2004 this language has also been able to program embeddedhardware, using the modules LabVIEW SDK and LabVIEW for ARM. This thesis shows how LabVIEW for ARM converts itsgraphical language G to C and then how C is flashed into the microprocessor. The thesis also takes up the pros and consof using G for embedded development.

This master thesis is an in-depth study of an existing heating system at a household cooperative in Uppsala that has been converted from district heating to a bedrock heat pump system. The study focuses on an economical system optimisation of the building?s complete heating system. The aim was to determine how well a heat pump system in large buildings actually work, find out possible ways to optimize the existing system and point out important system parameters for new heat pump installations in larger buildings.The project points out a possible energy cost reduction of 45 % without investment and further cost reductions with equipment investments. A reduction by 30 % is possible by improvements in the regulation system and 15 % is possible by maintaining the brine system.

In today?s society there is an increasing demand for renewable energy sources such as sun and wind power. These sources are intermittent, and energy storage is therefore needed to ensure a constant power supply. This report compares pumped hydro energy storage (PHES), compressed air energy storage (CAES), flywheels, batteries, super magnetic energy storage (SMES) and hydrogen energy storage.The opportunities for further development are limited for PHES and CAES in comparison with the other technologies. Lithium-ion batteries and hydrogen energy storage are considered to have the most potential in the future.

Basal cell carcinoma (BCC) is the most common non-melanoma skin cancer. It can be divided in different subtypes. The most common type is superficial and is most frequently occurring on the trunk and on the face. In severe cases it can be difficult to differentiate basal cell carcinoma from other skin tumors, therefore a skin biopsy is conclusive diagnostic method. In terms of treatment, curettage is a common non-surgical treatment of basal cell carcinoma.

Sustainability reports have during the last decade had a strong development. Both in terms of establishing a sustainability assurance, in its form, and get it assured together with standards, principles and regulations which organisations and accountants have utilized. The growth of sustainability reports and the choice of getting them assured have in particular favoured the accounting business. Due to this result, some critics have voiced that assuring a sustainability report gain accounting firms more than it gains the actual organisation. Other say that it is necessary in order to increase the credibility and the eligibility of the report, while it also has become a requirement from stakeholders.

Type 2 diabetes is a growing disease in the population which includes that older people are a risk group. With the disease grows even cost?s. A lifestyle change is a major part of the treatment for type 2 diabetes. There are several factors that suggest positive effects on prevention among the elderly where, among other things, economic and health benefits are presented.

This master theses deals with different methods for automatic tuning of the existing controller for external axis. Three methods for automatic tuning have been investigated. Two of these are based on the manuell method used today. The third method is based on optimal placement of the dominant poles. Different sensitivity functions are important for this method.

The cost for forestry logistics in Sweden is about 25 percent of the total cost of getting the raw material to industry (Anon., 2010). There might be much to gain by taking a look at your supply chains on the logistic side in your company. In this report the logistic chains by Mellanskog for ENA Energi AB in Enköping has been looked in to. ENA Energis plant is a combined power and heating plant and about 99, 5 percent of their fuel consisted of bio energy in year 2009 (ENA Energi, 2011, länk A). The main purpose with this report is to look at three questions: 1. How does the supply chain look today? From forest to industry. 2.

Introduction: Dental health globally is not equally distributed as shown by caries prevalence is higher in areas with more immigration outside Scandinavia and Western Europe and areas with lower socioeconomic status. To reduce the health inequalities in Borås, a dental health project was made in five kindergartens in the district Hässleholmen. Purpose: The purpose of the survey was, by interviews with the actors involved (teachers, children, parents and the public dental service) find out the views of the project, and whether the project is relevant and should continue. Method: The method used was qualitative interviews with the actors involved in dental health project. A total of 21 interviews were then consolidated by a qualitative content analysis.

Evaluation of machinery costs is necessary for selecting appropriate farm machinery. Timeliness cost due to untimely operations is an important component of machinery costs. Timeliness costs can be high for crop sprayers, since pesticide application must be carried out within a short time interval. This Master thesis investigated the timeliness cost and the probability of a suitable workday for spraying. Timeliness factors were estimated for four different crops (oats, spring wheat, winter wheat and barley) using historical weed trial data.

The aim of my study is to answer the question whether there is a potential for services by working horses in the Swedish municipalities. The Swedish University for Agricultural Sciences (SLU) and Swedish Farmers Union (LRF) has started a cooperation called Climate School (Klimatskolan), with the purpose to increase knowledge in environmental and climate related issues in context of agriculture. This Master thesis is in the framework of the Climate School.Global warming is a problem that gets much attention today. Global warming and climate change are two subjects that are very much in focus on the political agenda. The municipalities of Sweden have a big responsibility concerning environmental work and to develop their own environmental thinking.
