Påverkan av skogsbrand på litiska arkeologiska fynd ? experimentell simulering av brand
This is a paper about the effects from smoldering fire on lithic objects from an archaeological view.
The introduction gives the background to this paper, a short orientation to forest wildfires and why the work is limited to: flint, quartz, quartzite and slate. Material and methods describes the stone materials and the setup that was used in the temperature logged tests with three replications for each type of material. The fuel in the burnings was peat on a bottom of sand. Flint showed a more drastic effect from heat compared with the other materials. Slate seems to have greater tendencies to change to darker colour and luster at lower temperatures than the other materials.
Uppvärmning av mjölkgård med ved, flis eller havre :
The background for my thesis is the fact that with rising electricity and oil prices it becomes interesting to calculate on alternative heating systems. I have chosen to calculate upon my parents? farm, which today heats the dwelling house with wood. This is very time-consuming work, time which could be spent on other work.
The main objective for this study is to compare three different heating systems to decide how they differ considering effort and cost.
The result from the calculations was that grain-heating system demanded the least amount of work, but the total cost was a little higher compared to chips heating. Chips heating required half as much work as today?s wood heating and had a little lower total costs compared with the corn heating.
Which system to choose largely depends on how the own work is valued.
Elevers föreställningar om vattnets kretslopp och växtens liv : Har eleverna tillräcklig kunskap inom dessa områden för att diskutera hur miljöförstörning påverkar vatten och växter?
The purpose of this investigation is mainly to study if pupils have enough knowledge concerning the water cycle and the life of the plants?, and what kinds of household word they have, to discuss pollution within these areas. I also studied how the pupils? knowledge are holding up against what the course-plans says, since it have come to light by other investigations that knowledge are insufficient within the nature-oriented (No) subject in school.The survey has carried out on 28 pupils in a 5th grade, with help of a questionnaire survey. Their teacher has been interviewed and I have studied their local course-plans and also the pupils? schoolbooks in No.The result of the questionnaire survey indicates that the pupils had insufficient knowledge within the areas of plants? life and pollution, something their teacher had a presentiment about.The conclusion is that they need to go out more often in the nature and see how the plants and the environment are affected by different factors.
Själv- och kamratbedömning : En undersökning av lärares och elevers uppfattningar kring själv- och kamratbedömning.
In this thesis I set out to study how the reading of fictional literature is viewed, legitimatized and operationalized in two educational domains: the recently revised steering documents that all Swedish teachers must relate to, as well as a selection of teaching materials designed for education in the Swedish language for upper secondary school. The teaching material I have studied has been recently updated in order to correspond with the new steering documents. I relate my analysis to previous research about the use of fiction in education, and I also combine my analysis of the two educational domains to see whether the underlying intentions of the steering documents have influenced the revision of the teaching material. The outcome indicates that the steering documents? previous focus on culture has diminished although a certain insecurity as to how to use the concept and deal with the issue of whose culture should be taught can be identified.
MON En mittpunkt i periferin
This thesis takes its starting point in the humanistic cultural-geographical concept of place, with the aim of achieving a greater understanding of what constitutes the place Mon today. Mon is located in the northwestern part of Dalsland. Until 1879, the area was described as outlying land, but with the extension of the railway between V?nern and the Norwegian border, Mon's station community emerged. In the mid-20th century, all activities in Mon were phased out, and since then, the place has been inhabited by only about 10 year-round residents.
Naturvårdsavsättningar vid avverkning på Orsa Besparingsskog
Orsa Besparingsskog has an aim to take nature considerations in relation to the harvested volume and area of the annual felling. Around 15 percent of the acreage and 10 percent of the volume should be set aside. It is important to keep close to those figures to avoid future negative effects on the long-term harvesting planning. The purpose of this study was to use laser scanning data to estimate those proportions.
The result showed that the proportion of conservation considerations in the ten selected objects in the study was significantly higher than the target of 15 percent of the acreage and 10 percent of the volume. The result showed a setting aside of 19 percent of the acreage and 17 percent of the volume.
Beräkning av direktljud genom homogena betongväggar : Densitetens och tjocklekens påverkan på reduktionstalet
Today's urban centers become denser, which contributes to higher demands on sound and noise. It is therefore highly relevant to build homes with good sound environment while maintaining living space. This thesis aimed to reduce the current concrete walls and see how the mass law affects the reduction index value and flanking transmissions. Handmade calculations were calculated according to the Swedish standard SS-EN 21354-1, where only air sound was calculated.Calculations were performed on wall elements with different weights and thicknesses, and compared with results from Bastian.In Bastian calculations of flanking transmissions were also made, this was made to see the impact of the flanking transmission when changing the mass per unit area. Mass law's impact was examined by flanking transmission and the result shows that they are not affected as long as the ratio between the thickness and the density remains the same.A questionnaire survey was conducted to determine the actual sound experience; this questionnaire was conducted on three concrete buildings in Växjö.

SUMMARY
Establish a pasture
There is many valuable nature and culture landscapes in Sweden that has developed during a long period of time, throw natural processes or human use. Unfortunately lot of these are disappearing. My thought with this work is to explore the possibility to establish new areas with similar qualities. The motive for this is that attractive countryside biotopes are well worth to use as model to enrich the urban landscape.
Another thought has concerned the people that establish, build and manage landscapes and parks. They often have varied views, both coming from a difference in background and previous experiences.
Regionala och sociala skillnader i hälsotillstånd : En jämförelsestudie av Danderyd och Rinkeby
Sweden's population holds today one of the highest life expectancies in the world and an increasing number of Swedes believe that they have good health. However, the problem still remains that there exists significant differences in health between different population groups and neighborhoods. Two neighborhoods that demonstrate high inequality in health status are Rinkeby and Danderyd in Stockholm County. The purpose of this study was to examine why health differs between different neighborhoods and how residents experience the area and their health. To answer this purpose a combination of statistical data and qualitative interviews with residents in Danderyd and Rinkeby has been used with an additional literature review. The study showed that the causes of health inequalities between these neighborhoods was primarily concerned with the factors of education, economic conditions, ethnicity, conditions of comfort and companionship and the surrounding residential environment. The population in Danderyd, made up largely of people with high education, good economic conditions and few foreign-born, while the majority of Rinkeby?s population consists of individuals with low education, poor economic conditions and a high proportion of inhabitants of foreign origin, which are determining factors leading to poorer health status among the population.
Långsiktsplanering med geografiska hänsyn : en studie på Bräcke arbetsområde, SCA Forest and Timber
skogsföretagens långsiktigt strategiska planering sker idag i de flesta
fall med
Indelningspaketet (IPAK). För överföringen från strategisk till operativ och
objektsorienterad planering finns ingen vedertagen rutin.
Syftet med denna studie, som initierats och finansierats av SCA Forest and Timber, har
varit att utveckla en rutin för långsiktig operativ planering. Kravet var att
planeringsrutinen skulle vara kraftfull nog att implementeras på ett stort skogsinnehav,
i detta fall ca 90'000 ha. Planeringsrutinen omfattar åtgärderna slutavverkning och
gallring.
Den kvinnliga anatomins sociala konsekvenser : En kvalitativ studie av argumentation och doxa i förändring rörande den svenska aborträtten
Abortion remains a contentious issue, which greatly raises ethical problems. This thesis examines the leading arguments in the Swedish abortion debate around the ? in terms of legislation ? critical years of 1938 and 1974. With Foucault's genealogical method, Butler's theories of gender as a social construction in relation to power and doxa, the study examines what the development of the argumentation says about the views on morality, the woman's body, life, individual and state? How has the arguments pro and against abortion changed over time and what does this say about the norms that guide and orientate the arguments? The most obvious change in argumentation is seen in the shift from an absolute moral and conservative position into an increasingly relativistic and liberal position, and this study will argue that this shift has its prerequisites in the changing status of the citizen and state.
Den ena boplatsvallen är den andra lik? : Miljöarkeologisk intra-site studie av boplatsvallar vid Lillsjön, Anundsjö sn., Ångermanland
Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as ?embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden. This view of the ancient monuments carried over, to a certain extent, to this new definition. Should this be the case, that this category of ancient monuments are remains of winter settlements, used recurringly over an extended period of time, then they should exhibit similar signals in regards to the distribution of the anthropogenically altered soil chemical and soil physical properties at the sites.The area around Lillsjön, Anundsjö parish in Ångermanland, have four boplatsvallar located separately in the regional area.
Den svenska äldrevården : Behov, konkurrens, kvalitet och valfrihet ur ett fastighetsperspektiv
In this thesis an explorative study was undertaken with the aim to study how a number of private care providers, as well as politicians and officials from councils in and around the Stockholm and Uppsala counties, think about the future of the Swedish elderly care from a property perspective, i.e. homes for the elderly. The analysis shows that there is a demand for capacity in 6 out of 16 municipalities, and that the property is an important part of this capacity, and the fulfillment of it. This was mainly due to the cost of capital, but also because of several other factors such as lack of land, a wish to guide the design, ideology, and in many cases a wish to use the property as an instrument of domination to control private health care providers.Also, the property was show to be connected to economic competition, to freedom of choice, and to quality. The problems related to the property in the market for elderly care still remains to be solved.
Tillväxt hos Husmossa (Hylocomium splendens) i boreal skog och växthus : effekter av ökad vattentillgång
Hylocomium splendens (Glittering wood-moss) is a common species in the Nordic countries and can be found in many different types of boreal forests. It usually forms dense moss carpets on the forest floor. The shoots grow in segments and new segments form annually on the previous years growth. The size of the segments is probably regulated in a high extent by local micro environmental conditions. Previous experiments suggest increased growth of H.
Skattemässiga aspekter på generationsskiften av skogsfastigheter
I Sverige finns det ett stort antal skogsfastigheter som årligen ska genomgå generationsskifte, det vill säga överlåtas inom familjen. Vid ett generationsskifte uppstår vanligen problem av ekonomisk karaktär, där både överlåtare och mottagare av skogsfastigheten är intresserade av att minimera skattekostnaden, vid tidpunkten för överlåtelsen. Dock är det viktigt att även ta hänsyn till den framtida ekonomiska situationen för både överlåtare, mottagare och eventuella syskon.
Syftet med denna studie är utreda vilka för- och nackdelar som finns med olika överlåtelseformer vid generationsskiften av olika typer av skogsfastigheter. Målet med studien är att finna ett bidrag till rådgivningsunderlag som fungerar för skogsfastigheter med olika familjesituationer och ekonomiska förutsättningar.
För att genomföra denna studie har en litteraturgenomgång angående skatteregler som påverkar ett generationsskifte, samt de olika överlåtelseformerna, genomförts.
