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.

Our environment affect us, not least gardens. By practising the ancient Chinese art feng shui, one could find tools how to create harmony and balance in gardens. By paying attention to different energies working with colours, shapes and materials one can create a nice garden with good feng shui. The philosophy, however, includes much more than what plants or what hard materials to choose in the garden. It describes different energies, the movement of energies, which we can learn to live in harmony with.

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.

This paper is the result of an osteological study of the skeletal remains uncovered during an archaeological excavation of the medieval cemetery in Norra Nöbbelöv. The purpose of the study is to compare the material from the rural site (Norra Nöbbelöv) with materials excavated from the old medieval graveyards in the city of Lund. The aim is to try and shedsome light on the question of whether there is any difference in the occurrence and frequency of fractures and osteoarthritis in the materials compared. The first section of the paper consists of a short historical background of Norra Nöbbelöv and Lund, a chapter on ethics, general results of the analysis and the methods used. Thissection was co-authored by Ulla Zagal-Mach and Åsa Strandh.

This essay focuses upon the Kivik monument and its conservation difficulties, since its discovery at 1748 until modern time. The Kivik monument is found in southeast of Scania, and dated within the Bronze Age period. The perspective of the conservation on the monument has merely been on the monuments inner cist of stone and the rock carvings on the cist-slabs. When the monument was first archaeological examined at 1931, its sizeable cairn (75 m in diameter) had almost vanished and the cist was sheltered by a casing of concrete and metal roof. Between 1932 and 1933 the monument has undergone a large-scale restoration, and this criticized restoration resulted in a low antiquarian value with the responsible authority.

This study is done on behalf of Södra skogsägarna in the autumn of 2012. The main purpose of the study is to get an explanation to why some of the members are passive in their forestry, and how Södra can stimulate them to become more active. To achieve this a questionnaire study was conducted on the members of Södra in the community of Gislaved. The result of the study shows that there are many different factors that influence whether the forest owner is active or not. Examples of those factors are timber prices, the forest owner's objectives and the forest owner's financial situation. The main goal for the forest owners in the survey was to obtain high economic result and to increase the standing timber volume for the next generation.

The purpose of this essay is to see if villages or bigger settlement locations can be found in south-eastern Blekinge during the viking age. There have been many archaeological findings from this period in Blekinge, for example grave findings, ring-forts , old roads and ancient harbors. But no evidence of a village has been found yet. If south-eastern Blekinge is compared with the area surrounding Järrestad on Österlen in south-eastern Skåne and the area surrounding Sorte Muld on Bornholm, many likenesses can be seen. In this essay, the findings in Blekinge will be used as different components when the three areas are compared with each other.

The castle Vivesholm is located about two miles north of Klintehamn on the west side of Gotland. The castle was built around year 1395 and burned down in the end of the 14thcentury. Around the 17th and the 18th century the castle was re-used. However, the emphasis on its use is during the middle ages.This paper aims at getting an insight in the animal husbandry at Vivesholm by analyzing the osteological material. The analysis revealed that bones from sheep/goat were more common than bones from cattle.

The project objective was to make parts of our cultural heritage available as a resource for learning, by developing the pedagogical activities on a medieval castle, that today functions as a museum. I also wanted to explore the role of a designer in a process that aims to develop the interaction between schools and cultural institutions.By a selection of objects and locations in the castle, illustrations with accompanying texts were made, which through the children?s imaginative ability may bring them to a historical scenario. This resulted in a working material that supports the children?s activities and reflections during their visit to the castle.

For some time, there has been a general thought that churches built in the Early Middle Ages in Scandinavia, around the 12th century, directly replaced cult buildings or cult sites from the Late Iron Age. There are archaeologists who have criticized this and were instead skeptical that churches at all were built on places where a pre-Christian cult building existed. Several examples from Scandinavia contradict this and show a continuity of place and cult from the Late Iron Age to the Early Middle Ages. The aim of this thesis is through a spatial analysis, study Late Iron Age archaeological sites in the landscape around thirteen churches located around lake T?kern in the western part of ?sterg?tland, to see if there is a place and cult continuity from the Late Iron Age to the Early Middle Ages at the selected locations.

Intresset för biobränsleproducerad energi har ökat i takt med att kunderna blivit mer miljömedvetna. På grund av detta har efterfrågan på briketter ökat samtidigt som träindustrin har haft det svårt i en sviktande konjunktur. Därför har ett examensarbete utförts i samarbete med E.ON Värme Sverige AB där undersökningar på bränslebyte i pannor avsedda för torra bränslen till fuktigare, stamvedflis har utfört.För denna undersökning har begränsningar införts på övre och undre effekt i form av uppehållstid och slutförbränningstemperatur. Intervallen är enbart beräknade på stamvedflis med 30 och 40 % fukthalt.Undersökning visar att det går bra att elda stamvedsflis i briketteldade pannor utan att emissionerna ökar så pass mycket att villkoren för anläggningarna överskrids om lasten hålls inom vissa intervall. Det möjliga effektintervallet ökar med minskad fukthalt på bränslet.Undersökningen har visat att det är bränslets kvalitet som är den mest begränsande faktorn..

I arbetet med en stol har jag utgått från det ursprungliga i trä. Min vision har varit att bevara och lyfta fram materialets inneboende och primära egenskaper.Jag har formulerat en bild av detta:-En gåtfullhet ligger som dagg över stolen och speglar den magi man kan finna iskogens träd.Min tillverkning bygger på en ärlig utformning gentemot trädet. I vårt nutida Sverige med masskonsumtion av möbler glöms materialens ursprung bort. På grund av det högteknologiska raffinerandet av materialet döljs tillverkningsprocessen. Jag vill visa materialets ursprung och låta brukaren förstå att trä har varit levande.
