I Västerbotten täcks den produktiva skogsmarken till 44 % av tall. Tallar bildar kärnved, men anledningen till detta är fortfarande oklar. Det antas dock innebära fördelar att bilda denna typ av ved. Kärnved består av döda parenkym och epitelceller, medan splintveden innehåller levande celler. Kärnveden innehåller även olika typer av extraktivämnen samt fenoler.

Live exports of animals began during the late 19th century and are nowadays a valuable alternative to the slaughter industry in Australia. About four million sheep and half a million to one million cattle are exported annually from Australia to the Middle East and Southeast Asia. Most of these animals are exported for slaughter, but some cattle are exported with the purpose of breeding. One factor that has been the driving force for the live export industry is that countries through tariffs and other barriers have favored the import of live animals rather than the import of meat.The export means that animals with a great cognitive ability are exposed to a long chain of production from the farm to the market and there are many factors that can affect the welfare of the animals in a negative way. Some of the most serious are high temperatures and a high stocking density, although seasickness, noises and handling can also have a negative impact on the welfare of animals.

Following paper deals with the questions about prehistorian and medieval settlements in the Mälar Valley and their relations to the historically known hamlets or single farmsteads from the 17th- and 18th-century cadastral maps. Models over settlement development through the period A.D 200 to 1700 done by geographers Ulf Sporrong and Dan Carlsson are tested and compared to the knowledge won by recent archaeological excavations. Is there a connection between the older settlements linked together by dry-stone walls and the late Iron Age settlements? Does the picture differ from the one presented for the Gotland region? How well are the general theories about different settlement development depending on basic natural conditions as for the potentials for cultivation and topography, corresponding to the physical remains?  Are there other factors involved when the settlement structure takes its form?The methods that are used here constitutes mainly of a comparison between different locations in the Mälar Valley that has got a well known prehistory thanks to extensive archaeological excavations. Cadastral maps, soilmaps, topography maps and maps over ancient monuments are intertwined to the same map and analyzed through works in Geographical information systems.The results of this study reveal an interesting suspicion in the continuity-question through the Iron Age.

User comments:Availability and Utilization in Online News Affiliated with Local Daily PressAuthor: Susanne AlmgrenSupervisor: Mats EkströmConstituent: Dagspresskollegiet (Annika Bergström/Ingela Wadbring)Course: Term Paper in Media and Communication StudiesTerm: Spring Term 2012Pages/word count: 91 pages / 38 334 wordsObjective: To examine the users availability to the user comment feature and how theusers utilizes the user comment feature in the context of an online news site affiliatedwith local daily press.Method: Mixed methods approach, content analysis and discourse analysisMain result: In this context, three out of four news stories (76.5 percent) has beenallocated with the user comments feature. The highest availability to the user comment feature was found in news themes covering sports and entertainment, followed by financial news. News stories lacking the user comment feature weremainly found in news themes concerning crimes and accidents. The user comment frequencies are not normally distributed along news stories. On the contrary, 62 percent of the news stories did not get any user comments at all.

This thesis is built on a field study that was carried out in two seed-tree stands near by Götbrunna in Uppland, Sweden. The aim was to examine if scarification carried out in spring time could generate a more dense seedling establishment when using natural generation, than scarification carried out in autumn. It was also investigated whether there were differences in mortality the first season between the two plot-types. Plots were established block-wise with 50 blocks (pairs) on each site. The spring scarification was made with a hoe during 22-23 of April.

In the low-income countries of the world, rapid urbanization and decaying infrastructure results in an increasingly unsustainable situation when it comes to solid waste management. Often, the solution tends to focus on introducing technical advanced interventions based on the conditions of the high-income world. However, this thesis aims to ?nd site-speci?c solutions on solid waste management at a local scale. By taking in consideration of local conditions a customized approach is possible where the solution is not dependent on expensive structural changes.

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.

Soils in a metal contaminated site on Stångberget in Gusum in southeastSweden were investigated and compared to relatively unaffected soils a fewkilometres away. Pollution came from historical release of untreated flue gasesfrom a brass mill. The objective was to find information on how high the metalconcentrations are, if metals from the polluted soil affect the surroundings andif the metal contamination affects the microbial community. The soil wasinvestigated using several different methods, such as field XRF measurements,chemical analysis of metal, carbon and nitrogen content, pH, acid neutralizingcapacity, texture, soil depth, field leach tests, sequential extraction and microbialfunctional profiles. The study showed that copper and zinc concentrationswere above Swedish Environmental Protection Agency guidelines for lesssensitive land use on the entire investigated area.

Abstract Contemporary cities find themselves today in a fierce competition against other cities over company establishment and in -migration. In this competition, the city?s main objective is to become an attractive site of capital accumulation.  As this happens, the pressure on the vulnerable groups in society increases, leading to a social geographic polarization. I have examined how the shift towards neoliberalism has affected a city on the fringe as Kalmar. How is the postindustrial urban space constructed? I found this important to analyze since it put two important questions in the light: For whom, and for which purpose do we build the city today? My questions have been:v  What are Kalmar municipality?s strategies to develop Kalmar?v  What are the results of this strategy in the urban space?v  What are the consequences of this strategy?The research has been a case study of the city of Kalmar with a qualitative deductive approach where David Harvey?s theories about the city in a capitalist system have been the underpinning structure.

Vaccinology is an ever expanding field. As a member of the veterinary staff it is important to stay up to date with the continuous new scientific data and recommendations that affect the care that our companion animals receive at the veterinary clinic. This paper presents adverse vaccination reactions, their cause, risk factors and suggestions how we can minimize the risk of adverse vaccine events in dogs. Dog owners in Sweden were allowed to answer a questionnaire about adverse events following vaccination. Lethargy, edema and pruritus were among the most frequently seen adverse effects.

ur society is today in a phase of development in environmental and sustainable thinking. Alarming reports show changes in climate caused by our load and exhaust of resources. The energy usage contributes to a big part of it, by its emission of carbon dioxide. The built environment uses around 40 % of the total energy consumption in Sweden and requests to strongly reduce it are presented from both EU and national level.This thesis brings up the subject of green building with a focus on how we can create more energy efficient buildings in projects of new construction. Since the construction industry today often fails to pass on the knowledge between different projects, as a return of experiences, the construction company Skanska suggested the topic for this thesis.

The purpose of this study is to examine the usage of IT technology within preschool and study how IT tools are used by preschool staff for administrative as well as pedagogical assignments. Several aspects affects the work preschool staff do with IT which concerns availability to technology, how technology is used and how technology is made available for the children. There are a number of questions linked to these aspects where some examples this study examines are which advantages, disadvantages, obstacles or other limitations that comes with introducing IT? This study also examines how, when and in what contexts IT is being used? Other questions examined are the pedagogue?s general views of IT, competence development and eventual needs of investment? Further on this study examines to some part how children interact with IT during pedagogical activities? The overall objective is to shed light on problems that preschool staff encounter  in their daily work and on the basis of identifying important questions at issue that could constitute a basis for further research. The results of this study are based on both a literature review and a field study.

When visiting Scaniaparken in Malmö you have the possibility of listening to music streaming out of grass-covered hills. In Helsingborg children can compose their own music and play for their friends on the playground. On a square in Nacka Strand you can hear birds singing in the quiet intervals of traf?c. What the places have in common are that they all contain sound installations.

Griskött är det kött som konsumeras mest i Sverige, och en allt större del av köttet som konsumeras täcks av import. Utomhusproduktion av grisar skiljer sig mellan olika länder vad gäller både förekomst och utformning. Produktion utomhus likställs ofta med ekologisk produktion, vilket inte alltid är fallet eftersom det även finns konventionell utegrisproduktion. Det finns utomhushållna flockar som bidrar till det konventionellt producerade grisköttet i vissa europeiska länder, framförallt i Storbritannien och Frankrike. Moderna framsteg som elektriska stängsel, terrängfordon, öronbrickor i plast och förbättrade hyddor där suggorna kan grisa har bidragit till en mer konkurrenskraftig och lätthanterlig utomhusproduktion. Syftet med denna litteraturstudie var att få en ökad kunskap om konventionell produktion inomhus och utomhus genom att jämföra de två produktionssystemen med avseende på reproduktivitet och produktivitet.
