Kan man genom kartstudier förutse häckningsframgång för ängshök (Circus pygargus) i Uppland? :
Montagu´s harrier (Circus pygargus) is a diurnal, Eurasian raptor, which migrates from its northern breeding grounds to winter in sub-Saharan Africa. In Sweden, its core breeding area is centred on the island of Öland, with a stable breeding population of approximately 40 pairs. The province of Uppland is on the northern end the distribution range, where 4-8 pairs have regularly bred since the 1980s.
In Sweden, the Montagu?s harrier is classified as an endangered (EN) species. This classification is partly due to a lack of preferred nesting habitat, such as shrub-lands or dense wetlands with Claudium spp.
Eldens arkitektur : En studie av de medeltida varmluftsugnarna och deras betydelse
AbstractThis thesis examines and discusses a sample of the medieval hypocausts (stone-heating ovens) in the Baltic area. The medieval construction is thoroughly explained as well as the antique hypocaust in order to establish a base for the following discussion. The medieval hypocaust has been almost forgotten for a long period of time. The last time someone dealt with this category of finds were in the 1960?s by Swedish archaeologist Iwar Andersson and in the 1970?s by Danish archaeologist Johannes Hertz.
Uttryck i sten : En studie av röjningsrösen, stensträngar och husgrundsterrasser under mellersta järnålder i Uppland
This thesis deals with two types of agrarian remains in relation to settlement remains; clearance cairns, low stone walls and house terraces in the area of Northeastern Uppland and the area north of Lake Mälaren, during the middle Iron Age. The aim whit this thesis is trying to get a better understanding of the relation between agrarian and settlement remains in Uppland. Three places have been chosen where these three elements are present and they are interpreted through Richard Whites concept of middle ground but also Landesque capital. The three elements have shown to be expressed in different ways in all three sites. It is possible to see two areas with different traditions, but also to see two areas that closely interact with each other, this opens up for a new discussion around agrarian remains in both areas.
Ekonomisk utvärdering av betonggjutformar
This report will try to evaluate the use of rented concrete casting moulds, which are used to build walls and system of joists. The evaluation is only examining the economical aspects.The cost of using concrete casting moulds is a big part of the total production expenses. Therefore it is important that the calculated price not exceeds the final costs of the casting moulds. The calculated price is the price used in the process of making an offer.The evaluation consists of a comparison of the calculated price and the final costs for three building projects. It also evaluates the exploitation of the concrete casting moulds for each project.The report is made by Sven Gynne and Anders Alexandersson at School of Engineering, Jonkoping University, in cooperation with PEAB Jonkoping.
En pärla gör ingen kvinna? : En statistisk jämförelse mellan osteologisk bedömda gravar och dess gravgåvor under yngre järnåldern
I have statistically worked up a material from 228 graves from the late Iron Age in the area of Mälardalen.In my material I have gathered the incidence of combs, knifes, beads, weapons whetstones and torshammarsrings.I have found that beads are overrepresented in graves of women and whetstones in graves of men. I only found weapons in graves from male.I found no indication from my statistic hypothesis (Z-test) that a grave that contains more than three beads should define the grave of a woman. A grave that contains a lot of beads, more than 20, consider I as a female gender.Combs, knifes and torshammarsring are considered as gender neutral..
Porträtt av personer med funktionsnedsättningar : - En kvantitativ och kvalitativ undersökning om den bild SVT:s respektive TV4:s nyhetsinslag skapar av personer med funktionsnedsättningar
The study has answered the questions to what extent people with disabilities are involved in SVT- and TV4- news reports and how people with disabilities are represented in news reports. The material is based on 140 news items.The study has demonstrated that news reports SVT and TV4 have different grades of misconceptions about disabled people. Disabled people are constantly being reinforced by negative disabling terms, the disability being of central importance for the news broadcast and they still occur in stereotypical depictions. Through the image of disabled people forms the bed-rock on which the attitudes towards, assumptions and expectations of disabled people are based on. They are fundamental to discrimination and exploitation that people with disabilities face on a daily basis, and contributes significantly to their systematic exclusion from mainstream society.
Att utkräva ansvar - en analys av Vattenfalls verksamhet i Tyskland
With the expansion onto the international market almost a decade ago, Swedish energy corporation Vattenfall began it's breaking and burning of coal on German soil. Criticism aimed at Vattenfall peaked in the mid 2000s with the revelation of large quantities of carbon dioxide emissions and the re-location of villages and graveyards in German states Brandenburg and Saxony. The purpose of this thesis is to show where the responsibility for these activities lie. By analyzing the history of, and the political debate surrounding, Vattenfall, I will show that the prevailing policies of right- as well as left-wing parties in the 20th century were all, regarding this matter, market oriented. I will also show that these market promoting policies made possible a situation where the transparancy of, and state control over, Vattenfall were close to eliminated.
Just In Time : Effektivisering av materialflöden med hjälp av principer från Inventory Management och Production Management
AbstractManagement is a field that started getting attention in the beginning of the 20th century by Frederick Taylor. His publication is called the Principles of Scientific Management and is based on the principles of using scientific methods to find the best way of conducting each operation within a production facility. Many of Taylor?s principles may appear obsolete today but the matter of an effective material flow is still highly current. Efficiency is the relationship between the input into an operation and its result.
Klimatet på tre platser i Sverige 2071-2100 i jämförelse med Europas klimat 1961-1990 med fokus på temperatur, nederbörd och avdunstning : En analytisk studie från en simulering av Rossby Centres regionala klimatmodell, rca3.
Due to human influences on the climate an increase in Earth's mean temperature is today an accepted conception. With a rising temperature discussions have started how the climate in an area will change in the future. Equally interesting and important is it also to study the precipitation in an area. Precipitation is the factor, next to temperature, that affects most how a climate in an area looks like and feels. Since precipitation is connected to evaporation the latter parameter is also of interest to study.
Forensisk undersökning av Solid State Drive
Solid State Diskar (SSD) är relativt nya och mycket om dem är okänt. Detta examensarbete fokuserar på att läsa forensiskt viktig information från både lagringsutrymmet och reservutrymmet. Detta har försökts genom att ett program har byggts i C++, detta program använder ATA kommandon för att läsa information från disken. Även om programmet aldrig blev färdigt kunde det skicka och ta emot data från en SSD, dock inte reservutrymmet vilket var fokus i detta examensarbete..
Nötkreaturens val av betesvegetation på naturliga betesmarker :
This study concerns the type of vegetation selected by cattle grazing on semi-natural pastures, and whether the selection depends on the nutrient content of the vegetation or on other factors.
The study was carried out in three different semi-natural pastures in the Uppsala area during June, July and August in 2006. The three pastures were first surveyed, mapped out and divided into sub-areas with regard to the type of dominating vegetation. The vegetation types identified were: wet, mesic, dry, wooded, pasture with signs of former cultivation (arable). Within each vegetation type three 1x1 m sampling plots were laid out.
The grazing behaviour of the cows was recorded in a behaviour study.
Bedömning av skada på naturmiljö och rennäring för den föreslagna fjällvägen mellan Borgafjäll och Saxnäs : - Väg- och transportforskningsinstitutets metod för bedömning av skada på bevarandeintressen
Assessment of impacts on nature and reindeer husbandry by the considered mountain road between Borgafjäll and Saxnäs- Swedish National Road and Transport Research Institutes method for assessment of damage to heritage assetsThere are plans regarding the building of a new road from Borgafjäll/Båtas to Saxnäs, and two road alternatives have been presented. The road has been localized to an area which is protected as a nature reserve and listed as a Nature 2000 area. This report aims to determine the effects on the Nature 2000 area and reindeer husbandry, and to be a source of knowledge for future environmental impact assessment in that project. In order to assess the impact on nature values and reindeer husbandry a method from the Swedish National Road and Transport Research Institute (VTI) has been used. A literature review has been made to prescribe the effects and consequences.
Enumerating Atlantic salmon smolt production in River Vindelälven based on habitat availability and parr densities : consequences of using different density estimation methods
Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats. The mapping included 61 km of various stream sections along the river length of 269 km. The total area of stream habitats was estimated to 647 ha of which 396 ha (61%) were considered as either potential or optimal juvenile nursery habitats. The area of these two habitat classes were used to estimate the smolt production in the river by using electro fishing densities of juveniles (0+ per 100 m2).
Geografisk prioritering av CTI-utrustad virkestransportkapacitet
Previous studies of central tire inflation (CTI) in truck transport of roundwood have shown potential benefits to include more even wood flow and reduced road damage. The greatest benefits are found to be during periods of low bearing capacity such as spring thaw. No previous studies have examined geographical variations in the potential benefit of CTI-equipped trucks. The aim of the study was to develop and use a simple method for geographically prioritizing the use of CTI-equipped trucks within a forest company´s sector of activity.The host company for the study was Holmen Skog. The area studied consisted of Holmen Skog?s entire sector of activity extending from the province of Västerbotten to the province of Småland.
Skattningar i gallringsskog med hjälp av flygburen laserskanning : beräkningar med massaslutenhet
This master?s thesis is a remote sensing study of an area-based method used to detect forest in need of thinning by use of laser data and field samples. Only pine-dominated forest has been included in the study and height limits were set to match empirical restrictions. The study area was in the municipality of Älvsbyn (Latitude 65° 40´ N, Longitude 21° 00´ E), in northern Sweden.The Swedish authority Lantmäteriet is currently laser scanning most parts of Sweden, providing new opportunities and applications. The primary aim of the national laser scanning is to create a new elevation model, useful in consequence analysis of climate changes.
