The city?s public environments are meant to be perceived as safe and inviting areas to visit any time of the day. In recent decades the number of vandalism complaints has doubled and graffiti has become so common that it received a separate category in the crime statistics. With this type of impacts in the public environments the experience are precarious and a boring sight. It?s difficult to put a price tag on these types of crimes, the number of unreported cases suspected to be large.

Nowadays the majority of the thinnings made in Swedish forests are done by machines, harvesters and forwarders. The most common model in thinning with a harvester is strip-road operated thinning and stand-operated thinning with one intermediate passage between the strip-roads. This study is a time study with some quality follow ups on a strip-road operated thinning model, a stand-operated thinning model with one intermediate passage between the strip-roads and a stand-operated thinning model with two intermediate passages between the strip-roads. The machines in the study were a small harvester (Forestline MPM C90) and a medium sized forwarder (Timberjack 1110). The study was made in Litsnäset outside the city of Östersund in Sweden and was made during the autumn 2007. In a lodgepole pine stand six study units (0,6 ha) were thinned with the three different models, two study units per model.

Stormwater run-off from surfaces such as roads or rooftops is often polluted with heavy metals and nutrients. Many of these substances can cause great damage in biota if they end up in the recipient. In Sweden constructed wetlands and ponds for treatment of stormwater are frequently used, since research has shown that these treatment ponds are reducing stormwater pollution considerably to a low cost. The knowledge of these pollutant removal mechanisms and how follow-up and assessment of the ponds should be performed is still limited.To determine the pollutant removal efficiency of the stormwater ponds it is recommended that flow-weighted water samples are collected from both the inflow and the outflow of the pond. This method demands considerable resources of time and money for installations and analysis.

Syftet med denna uppsats var att undersöka vilka prisstrategier högteknologiska B2B-företag använder sig av samt hur dessa val av prisstrategi förhåller sig till tidigare forskning på området. Vidare har vi undersökt huruvida högteknologiska B2B-företag har någon gemensam karaktäristik som kan påverka valet av prisstrategi. Slutligen har vi diskuterat hur de högteknologiska B2B-företagens användande av analysverktyg kan påverka valet av prisstrategi. Vi har genomfört en fallstudie av åtta företag och jämfört dessa empiriska observationer med det teoretiska ramverket. Studien visar att högteknologiska B2B-företag i stor utsträckning använder sig av marknadsbaserad prissättning.

The forest property Fagerdal 2:10 was donated to the Swedish University of Agriculture in 1995 by Erik Rönnberg. The dominating species is Norwegian spruce (Picea Abies) and the average age is high due to selective cutting. The aim of this study has been to analyze how the forest on the property should be managed and demonstrate how a better estimated forest data affects the future management. The impact of the management on the carbon stock of the property was also examined. A forestry plan established in 2009 by Skogssällskapet was used as a basis for the analyses.

Uppsala like many other Swedish cities is affected by heavy housing shortage, in terms of too few existing flats and residents within the city limits. Every semester thousands of new students are facing the same problems of finding themselves adequate accommodation. The waiting lists for flats and student-dorms are getting longer for each year, and the situation is just getting worse. Simultaneously, Uppsala?s ambition is to increase its population and expand as a Swedish metropolitan, according to the Swedish governmental environment goals. This paper investigates and analyses the possibilities of expanding a city?s population by building high-rise buildings.

The purpose of this master thesis is to present a model that illuminates the important factors when deriving technical information from market data within a company. For companies to be able to become and stay competitive in the market, product quality is an important factor. Whilst good product quality leads to customer satisfaction and loyalty, lack of quality brings costs in service and replacements. To improve product quality, the developers need information and knowledge about what quality issues affect existing products. Most companies gather data from market about known issues, but in order eliminate known quality issues in new products; this data has to be transformed into information and knowledge.

The Swedish carrot market is dominated by a few big companies and three of them stands for 50 % of the market. During the last twenty years the number of growers has decreased, the area and the harvest have increased. The big producers have invested in advanced and expensive postharvest equipment that fulfils the high standards of the food industry. Few carrot producers are members of an organisation and they keep contacts with there buyers one by one. The buyers are mostly wholesalers and these have during a long period of time decreased the number of suppliers.

In conjunction with today?s increasing competition within the construction sector, more pressure is being placed on building contractors. Efficiency and improvements are necessary but without impairment to an ergonomic and safe construction site. This in is in order to reduce the construction costs and time but to retain the ability to deliver a high-quality contract.Various methods and prefabrication degrees are used, depending on the project's requirements and conditions. This analysis sets out to investigate and exhibit what qualifications are important when choosing a construction method for curtain walls.Advantages and disadvantages with each method have been analyzed and recommendations have been given to show when different methods are best suited.

The industrialization in Sweden has increased the large number of areas that have been contaminated with various types of pollution. One of those sites are the property Höjen 3:24 in Arboga where ?Arboga Mekaniska Verkstad? once been. The property wants to increase the use of the old former foundry building with the adjacent ?plate-workshop? and believe there are two options for the building: That the building either should be used as a warehouse/concert hall, or rebuilt into a cultural center. An environmental evaluation has shown that the levels of heavy metals are over the Swedish environmental protection agency guidelines of less sensitive land.

The design regulations of Boverket (BKR) have long been the mandatory standard for construction design in Sweden. However from the end of the year 2010, the BKR will be replaced by the European standard Eurocode (EC). The transition to EC has been delayed and it is not until the second of May 2011 that the use of EC will be mandatory. Because EC and BKR differ from each other it is highly interesting to investigate and explain these differences.The purpose of the thesis is to compare the two standards and investigate how they give different results or not for the dimensioning of structures of steel with associated loads. The current project HVC (Pets Science Center) in Uppsala is used as a model for the design of the steel structure used in this study.

This thesis provides a comparison of the old Planning and Building act (PBA) from 1987 with the new PBA, which entered into force in May 2011. The essay consists of a descriptive part that presents the regulation of both laws. The new PBA consists of several differences compared to previous regulation. This thesis will, however, primarily be centred around the regulation regarding building permit appeals and the possibility of building permit, to gain legal force.In the old PBL, there were no regulations that result in a building permit decision could be made effective. Instead, a building permit could, long after the decision had been made, be over-challenged.

Between 1965 and 1975 a major housing project was carried out in Sweden to resolve a major housing crisis, the so-called one million housing program (Swedish: miljonprogrammet). To raise the standards and create a more attractive housing in these areas is currently a very relevant topic in Sweden.Evidence-based design is the process of basing decisions of the built environment on credible research and studies to achieve the best possible outcome. This method is primarily used in the healthcare sector to improve quality of care and reduce costs by creating healthy environments.The possibility of refurbish apartment buildings from miljonprogrammet using evidence-based design has been studied by means of an extensive literature review and a closer examination of the residential area, Husby in Stockholm, which has been chosen to represent the miljonprogrammet in its entirety. Furthermore, the evidence-based research has been limited to seven fields; nature, noise, color, wayfinding, safe environment, daylight and thermal comfort which has been assessed to be applicable on housing. In order to obtain a comprehensive overview of the different fields, four different subjects were chosen to investigate further within each field; research and studies, laws and regulations, constructional aspect and Husby.

Dimensional stability is an important aspect of fuel mechanical design and licensing of new fuel designs for nuclear power plants. Dimensional changes within the reactor can affect the safety margins against overheating of the cladding and the pellets, therefore it is crucial that the dimensional changes are kept to a minimum.The profits per produced kiloWatt hour continue to decrease for the Swedish nuclear power plants. Some reactors are even operated with a calculated loss. To reduce fuel costs and thereby improve the profit some reactors are operated with higher uranium enrichment, so that the assemblies can reach a higher average burnup. This increases the neutron fluence to the pellets, cladding an spacers.
