Bergerosion i utskovskanaler
Today?s climate changes will probably give rise to precipitation in Sweden, which will cause more floods in Swedish rivers. Many of the Swedish rivers are regulated and have lots of hydro-electro power plants. Higher floods in the rivers will give greater water loads on the dams, which mean that a higher discharge through the sluice gates and in the spillway channels is needed. High discharge of water in a spillway channel can create scour of the material in the channel.
Återvinningsstationer på Lidingö : attityder och lokalisering
When the producers? responsibility for packaging was introduced in Sweden in 1994 the industry set up public recycling stations to facilitate the collection of the waste material. In order to establish recycling stations at suitable locations the municipalities assist the industry?s service organization for operation of the recycling stations, the Package and Newspaper Collection Service (Förpacknings- och tidningsinsamlingen, FTI). The objectives of this thesis are to improve the service of the public recycling stations within Lidingö town and to increase the accessibility to these stations for the inhabitants of Lidingö.

Picea mariana ((P. Mill.) B.P.S), P. abies (L.), Pinus contorta (Dougl.) och P. sylvestris (L.) : en jämförelse av produktion och potentiell kvalitet hos försöksbestånd i Jämtlands län
Swedish forests are dominated by just two conifer species Norway spruce and Scotch pine. They are not able to achieve the highest possible production or fulfill industry demands for raw materials. The introduction of exotic conifers can potentially meet these shortcomings and present a relevant solution.
This study was conducted in a block experiment with ten blocks planted in 1987 by SCA in North Sweden. The objective of the block experiment was to study if Black spruce is an appropriate alternative to Lodgepole pine, Norway spruce and Scotch pine on different site classes.

Den gudomliga människan : en komparativ studie av det tonganska hövdingadömet
This essay will examine the social organization in the archipelago of Tonga. To accomplish this purpose, archaic societies and structures such as ancient Egypt and Hawaii will be examined to obtain a closer understanding of the building blocks which constitute a chiefdom or kingdom. Since Patrick V. Kirch (2010) recently redefined the Hawaiian archipelago as a kingdom this essay will examine if the same can be done with the chiefdom of Tonga since it have similarities to the Hawaiian social organization.To do this the essay will examine and describe both the geographical organization of the states and the social organization. Social organization in this essay will be defined as an archaic state organization that requires several levels of administration to rule the society..
Medierelaterad krishantering inom livsmedelsbranschen
Vår avsikt med uppsatsen är att beskriva och analysera medias larmrapporters inverkan på livsmedelsprodukternas nuvarande situation och framtid. Vi undersöker varför vissa företag lyckas bättre respektive misslyckas med sin krishantering utifrån hur de bemöter larmen.Vi har utgått från teorin Crisis Management, där vi har funnit en applicerbar modell på vårt syfte, Crisis Response System, som kompletteras med sårbarhetsmodellen A Simple model of Crisis Susceptibility. Dessa modeller behandlar den interna krishanteringen. För att externt kunna bemöta larmrapporter har vi valt att tillämpa PR-modellen Communication Strategies for Responding to a Crisis där paralleller dras till delar ur ryktes- och trovärdighetsmodellen Brand-Building Blocks..
Design av slutsteg med digital PWM-teknik för gitarr
Softube has developed DSP-card and software for simulation of the sound of old tube amplifiers. The purpose with this thesis is to design a compact amplifier with high power to function together with the DSP-card and build a unit that can replace several other guitar amplifiers. The advantages with that kind of solution could be that it would be cheaper, easier to carry and easier to stor than the real amplifiers. The amplifier that has been designed is of class D type with digital PWM modulator. There is several types of amplifier modules on the market that use analog input signal, but if one of them would be used a D-A converter is needed on the DSP card.
Att bygga i trä eller lättbetong : en jämförelse mellan väggkonstruktioner
Hudiksvall Municipality will build a new preschool. The goal is that the pre-school should reflect the municipality's environmental goals and meet building regulations. The wall structures that are compared in the report is an insulated wooden frame and a frame of lightweight concrete blocks from H + HWall structures are compared within the areas of U-values, air tightness, thermal storage capacity, fire ratings, moisture, durability, emissions and environment. In these categories the two wall structures will be rated in a scale from 1 to 5 and then the categories are weighted against each other. The weighting is based on Hudiksvall Municipality's assessment of the categories importanse for their final selection.The results of the comparison show that the concrete structure is recommended for the construction of pre-school with 27.55 points against the wooden structures 23.70 points.
Beräkning av koldioxidutsläppet från bostadssektorn i Stockholms län
During the last decades the housing sector has increased continuously, and housings and services accounted for 40 % of the energy usage in Sweden during 2011. The expansion in number of buildings in society has resulted in an increase in both energy usage and emissions of greenhouse gases. It is crucial to enable a sustainable development of society and as a result, the demand to reduce the emissions of carbon dioxide is a current question. In this study, the carbon dioxide emitted from the housing sector in Stockholm is estimated. The housing sector can be divided into different types of houses such as apartment blocks, single-family houses and holiday houses. By collecting information of the energy purchased in respective households, a computational model is generated that calculates the total emission of carbon dioxide.
Sova med fienden - Orsaksförklaringar till uppkomsten av oheliga allianser i svenska kommuner
Over the last years there has been a considerable change in Swedish municipals. The number of municipals run by a rainbow coalition, a coalition made up of parties from different political blocks, has increased dramatically. Despite this clear pattern little research has tried to explain this increase. My thesis? aim is to try and clear the water around this subject by answering three questions about this type of coalitions.
Offer eller förövare? : En analys av Dagens Nyheters rapportering om mäns våld mot kvinnor under perioden 1994-2009.
The purpose of the study was to analyze how media, in this case, the daily newspaper Dagens Nyheter, produces the men and women in men's violence against women in close relationships in news articles and if there has been a change over time in this production. It is a qualitative study in which 40 news articles from DN were analyzed. The starting point in the tanks around the analysis is from a social constructive perspective. Critical discourse analysis is the method I chose to use in the processing of news stories. The result is divided into four different blocks where each block presents the results and the analysis for the following years: 1994, 1999, 2004 and 2009.
Vindfällning, tillväxt och plantuppslag i en 13-årig granskärm i Medelpad :
The interest for alternative forest regeneration methods increased significantly during the 1990´s after 50 years dominance of the clear-cutting system (Holgén & Hånell 2000). One reason for this was that clear-cutting was being more and more questioned by different envi-ronmental organizations and because the forest sector for economical reasons wanted to find cheaper ways to regenerate forests. In the beginning of the 1990´s two shelterwood experi-ments were established in a joint effort by Svenska Cellulosa Aktiebolaget (SCA) and the Dept of Silviculture, Swedish University of Agricultural Sciences (SLU). The experiments include various forms of cutting and shelterwood densities and represent productive spruce forests in central and north Sweden (Roggsjön in the province of Medelpad and Skikkis-jöberg in the province of Västerbotten, respectively ). The experiment next to Roggsjön has been reported earlier in three MSc theses, and is also the focus of this thesis.

Frånluftsvärmepumpens möjligheter i flerbostadshus
If a building is heated by a heat pump, it is of high importance that the heat pump has a high coefficient of performance. An exhaust air heat pump extracts heat from the building?s exhaust air. The air has a relatively high and constant temperature all year around, leading to a high seasonal coefficient of performance. This thesis examines whether it is profitable to complement an exhaust ventilation system with an exhaust air heat pump in an apartment block that already has geothermal heat pump, district heating, oil- or biofuel heated system.
