With the prospect of future construction on the Skutskär Pulp Mill property, Stora Enso Fine Paper has initiated an investigation of soil contaminants and a risk assessment of these contaminants. A soil and groundwater investigation has therefore been conducted on an open area of about 16 000 square meters, situated between the current wood room and digester house. To be able to integrate this study into an investigation for the whole industrial property, the study has been carried out as a phase 2 study according to the Swedish Environmental Protection Agency?s Methods of Inventories of Contaminated sites (MIFO).The site investigation has involved soil and groundwater sampling, together with the analysis of heavy metals and organic contaminants. The degree of hazard posed by the contaminants, the level of contamination, the potential for migration of the contaminants, as well as the degree to which protection of human health and the environment is required in the area, have been weighed together for an overall risk assessment of the area with regard to human health and the environment.The investigated area was built up by filling in the coastal waters.

In hydropower plants it is necessary to always have local power supply. Therefore, the plants are equipped with batteries as stationary back up power. Vattenfall Vattenkraft is using lead acid batteries but has been investigating alternatives to replace them. The aim of this study is to investigate the potential of using Li-ion technology as back up power.The study showed that Li-ion batteries have many qualities. The Li-ion technology will decrease the space and maintenance demand.

This essay captures the process toward a democratic transition in South Africa and tempts on analyzing the efforts made by civil society before the negotiation with the government in the beginning of the 90´s. The method used is a case study.By applying the theory of Elisabeth Jean Wood about the importance of continued mobilization, I try to answer the question: to what extend did civil society influence the democratization process. The focus of the study lies on the years of intensified popular mobilization, from the start of the 80´s until the beginning of the 90´s.The results following this study shows that COSATU, Congress of South African Trade Unions) and ANC(African National Congress) played both a crucial role for the democratization process in South Africa. UDF, however played a role in the process, but not in the same significant way that COSATU and ANC..

The City of Stockholm has decided to invest in renewable energy and especially in photovoltaics. The objective of this thesis is to investigate the photovoltaic potential on roof areas that the city possesses and to further investigate some buildings of the Property Management Department. The thesis also compares some existing photovoltaic plants with the solar irradiance map which shows available roof area on each building in Stockholm. The report ends with a literature study about the climate impact and greenhouse gas emissions of photovoltaic.The total available roof area suitable for photovoltaic plants is estimated to 700 000 m2, with a potential electricity production of 110 GWh per year. This corresponds to 17 % of the City of Stockholm?s yearly electricity consumption.

Följande rapport beskriver teori, metod och resultat av ett examensarbete vid Luleå Tekniska Universitet utfört i samarbete med Light My Fire AB. Företaget tillverkar produkter som används av människor i hela världen och som ger användaren ett leende på läpparna. En produkt som har saknats i sortimentet är en vätskebehållare och flera återförsäljare världen över har frågat efter just detta. Målet har varit att ta fram en multifunktionell vätskebehållare som ska passa in i Light My Fires befintliga sortiment och få plats i företagets produkt, LunchBox. Projektet började med en grundlig benchmarking för att ta reda på vilka olika typer av vätskebehållare som finns.

This essay is from a student at the cultural science program in Karlstad University. The essay in Culture studies deals about the history use and about the cultural-historical values on buildings. The buildings are from a certain area called the neighborhood Almen and have in the past been threatening many times of demolition. The neighborhood Almen buildings survived a huge city fire back in the 19th century. Since then the buildings has been known as a memory and by the inhabitants and as the oldest part of the city left.

My Finnish grandfather had a passion for architecture, eventhough he wasn?t an architect. In the end of the 1950s he builta wooden summerhouse on a lot outside of a small villagecalled Lempäälä, close to the city of Tampere. Today the lotbelongs to my mother. Every time I visit our summerhouse, itmakes me want to do as my grandfather did ? to build a smallhouse next to it.My project is a proposal for a wooden house on mymothers lot.

Ökad användning av byggtekniken massivträ kan ge ett positivt bidrag till hållbart byggande. Utvecklingen inom datornavigerad bearbetning ger massivträ möjligheten att rationalisera byggproduktionen inom trä. Tekniken ligger rätt i tiden och kommer att värderas allt högre då den tillvaratar materialets karaktäristiska egenskaper.Utvecklingen av massivträ har resulterat i teknikvarianter av hur virke kan sammanfogas till solida element. Ett behov har funnits av en marknadsjämförelse mellan befintliga principer där studien förtydligar grundläggande skillnader för intresserade byggaktörer. Problemfrågan för denna studie har varit: vilka principer för sammanfogning av trä till plattelement inom massivträ är mest fördelaktiga? Detta sett utifrån faktorerna produktionskostnad, hållfasthet och ekologiska övervägningar.För att förtydliga den undersökta byggmetodens nytta i ett vidare perspektiv har det presenterats en allmän beskrivning av massivträ.

Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.

Den här rapporten är en sammanställning av ett gestaltningsarbete där ett bostadshus i 5 våningar projekterats fram. Huset i fråga har anpassats till att kunna byggas med prefabricerade volymelement och enbart i stommaterialet trä. Prefabricerade volymelement är färdigbyggda rumsenheter, tillverkade på fabrik. Dessa kan vara så pass färdigställda att de levereras till en byggarbetsplats med färdig fasad och fast inredning. Eftersom arbetet baserats på volymelementsbyggande, har projektering skett efter de villkor och den byggteknik som då tillämpas.

This essay is about the burial rites in the passage graves of Falbygden, Västergötland. My questions were: Can the burial ritual be understood by comparing the material culture inside and outside the tombs? What kind of grave offerings did the dead have? Most peculiar are all these beads of amber, what kind of meaning did they have? Was the position of the body a part of the ritual? The time period is the middle Neolithic.I selected four passage graves to investigate: Hjälmars rör (Falköping 3), Rössberga (Valtorp 2), Näs sn 7:2 Kvättak 5:1 and Frälsegården (Gökhem 94).My conclusion was that there are differences between the material culture inside and outside the tombs. Outside the ritual includes fire, inside the material culture are not burned. The material culture outside is more dominant than the finds inside, although the beads of amber are only represented inside and dominates the findings inside.

A helicopter based system equipped with a millimetre-wave fire control radar is studied for improvement of the detection probability for moving ground targets. The system is a pulse doppler radar that sends out the electromagnetic wave in repetitive pulses. The frequency in which radar sends this pulse is called Pulse Repetition Frequency (PRF). The velocity of the moving targets is measured by spectral analysis of the pulses received. With this sort of system some targets will not be possible to detect.

The soil acidification and the pH-value of the soil have been discussed for many years. Many observations of the tree species effects on the soil pH have been done. We have discussed the effects on the soil surface pH-value with a birch (Betula spp. L.) admixture in Norway spruce stands (Picea abies L.).We have used data from the Swedish National Forest Inventory. We have also discussed how the wood production and the biodiversity can be increased in mixed stands, in according to the Swedish forestry act Skogsvårdslagen. Our sampling areas are located in Norrland, Sweden. The results show a significant correlation between an increased birch admixture and an increased pH-value of the soil.

In 1994 a new Forestry Act was accepted in Sweden. One of the aims of the law is to raise consideration forpreservation of biodiversity. Since the new law got accepted and some time has passed, there now lie someinterest in examining whether the law has been effective towards its purpose. Methods suitable for analysishave been examined during this study. The content of this pilot study is based around five parameters whichcan be used to validate the effects of the new law.
