Svenska hushålls vedarbete : en fallstudie i Umeåregionen
In Sweden there are 354 000 private individuals owning forest. Of these forest owners there are at least two thirds that are self-employed, which means that about 215 000 forest owners conduct some kind of work in their own forest. Those numbers do not refer to firewood production, but every year 7.3 million piled cubic meters of firewood are used for heating Swedish households. This implies that many households are also producing firewood.
The objective of this study was to assess and analyse the small-scale firewood production in the Umeå-region in terms of persons engaged in the work, equipment used, produced volumes and share of forest-owning households involved in these activities. According to results from a questionnaire, the average firewood producing person is a man between 40-60 years old.
Studie av en medeltida husgrund : en analys av bronsfynd från husgrund 6, Västergarn, Gotland
This essay is an analysis of the objects made of bronze found in an excavation Västergarn parish, Gotland, in 2010, conducted by the University of Gotland. The studied material presented in this essay comes from contexts inside, as well as nearby the foundation of a medieval building which purpose is still not certain. The first purpose of this study is to present the bronze-objects found inside and nearby the foundation of house 6, and to see if there are any datable objects. There is also a discussion whether there has been any bronze-crafting in the area. The second purpose is to make a contextual analysis to see if there are any differences between the material found outside and inside of the building, and what conclusions can be made regarding the function and use of the building.
Regaining power through construction of identity? Experience of Multisystemic Therapy from a Youth?s Perspective
Literature and studies exist on how to create services in the best interest of the client or how these services have an impact on individuals. They are however mainly from a social work professional stand point and rarely from how clients would develop and create the services that can imply a life change for them. Especially when working with children under 18 years old issues of agency and age that can result in the disregard of the Convention on the Right of the Child (UNCRC). The target group of this study is therefore youth between the ages of 15 to 17 years old in three cities across Sweden to allow them to voice their opinion and experience of being in treatment. Resulting from that is the aim of this study ? to investigate how an intensive treatment method like Multisystemic Therapy is described from a client?s point of view.
Analys av mjuka faktorer som påverkar grotuttaget från hygge till avlägg inom Sveaskogs organisation
Biofuels are getting more important as EU plans to replace fossil fuels with renewable energy sources. Because of that Sveaskog has chosen to invest in developing the handling process of logging residue. The company has a joined organisation for handling both round wood and logging residue. They are also working at integrating the forwarding of the logging residue with the rest of the harvesting team. Sveaskog is currently extracting 44 % of the available amount of logging residue.
Energieffektivisering av aerbo reningsprocess : Tillsats av biprodukter i skogsindustriellt avloppsvatten
In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.
Alternativa metoder för avhorning av kalv : teknik och behandlingseffekt, samt utvärdering av postoperativ smärta med användning av NSAID
In this study, cortisol in saliva and pain related behaviours in calves were used as markers of distress when comparing two different dehorning methods; scoop or cautery. We also investigated the effect of a non steroidal anti-inflammatory drug (NSAID), meloxikam, on postoperative distress after dehorning with either dehorning scoop or cautery iron.
Twenty calves were dehorned on one randomly chosen side by scoop method and on the other side by cautery. Five months later, the effect on horn growth was investigated. Horn production was observed in seven of the calves.
Utvärdering utav effekten av obturatbehandling vid restspalt/fistel hos barn med total läpp-, käk- och gomspalt
On children born with a complete cleft lip and palate (CLP) the repair of the alveolar ridge doesn´t take place before the children are about ten years old. This results in that they have a residual cleft in the alveolar ridge during their early childhood. This residual cleft, and the oronasal fistulas that may appear after the repair of the hard palate, can result in a negative influence on the speech of the children. Thereby it may be necessary with cover for examplewith a palatal plate or an obturator. At the Department of Orthodontics, at Linköping University Hospital, Sweden, some of the children with CLP undergo treatment with sustained palatal fistula obturation in order to cover fistulas or residual clefts.
Naturvårdande skötsel (NS) - blir resultatet som man tänkt sig? : en fältstudie över föryngring, trädslagsfördelning och död ved 14 år efter åtgärd
A new Swedish political approach to forestry was initiated 1993, that put goals of production and environmental issues into equal importance to Swedish Forestry Law. Earlier nature conservation very often declaimed preservation the best way to conserve nature, but recently it is clear that many highly biological values are due to former land use or disturbance. Many old pastures or cultivations dominated by deciduous trees are today characterized by a dense overgrowth of Norway spruce. By actively paying attention to nature in forestry (nature restoration), it is possible to partly reconstruct habitats or disturbances that are necessary to favour the biological values.
The aim with this master thesis is to study the nature restoration, (NS, Swedish abbreviation), performed in 11 forest sites in the middle of Sweden 8-14 years ago. Since NS recently have become applied, it has never yet been evaluated.
Strukturell konservering av måleri på duk Studie kring den långsiktiga stabiliteten hos Plextol D 360, Plexisol P550 och Beva 371
In the early 80s, several new synthetic materials have come to be used in the treatment of canvaspaintings, among them Plextol D 360, Plexisol P 550 and Beva 371. Today, many conservatorsfind the information about the long term sustainability of these binding mediums to beincomplete. Evaluation of synthetic materials is mostly done through clinical research, sometimesartificial aging is simulated. The correlation between artificial and natural aging is however notestablished, useful information can therefore be gained through evaluations of actualconservation treatments. The intention of this study is to find out more about how thementioned products perform over time in normal museum conditions.
Tillämpning av naturvårdsavtal :
Nature conservation agreement (NCA) is a way to voluntarily protect and manage nature for limited time-periods. The agreement is settled between the government and a landowner. All public authorities can represent the government but it is only the Swedish Forest Administration who does that regularly (because it is the only authority with economic resources for that purpose). Therefore, NCAs are almost only used to protect forested nature.
The government agencies have experienced NCAs for about ten years and it is now time to examine how they are applied in the forests. This study is based on a computerized questionnaire to the persons responsible for the LEKO-projekt.
Upplevelse av fotfunktion : efter konservativt behandlad hälseneruptur
Background: Previously research shows that people treated conservatively can have reduced foot function after Achilles tendon rupture. However, there are few qualitative studies in the subject, so this essay is written to provide a deeper understanding of how these people feel about their foot function one to two years after the injury.Purpose: Investigate how people perceive their foot function after conservative treatment one to two year after Achilles tendon rupture and if they have an avoidance behavior in their everyday lives.Method: Four people who suffered from Achilles tendon rupture participated in this qualitative study. The study was conducted with semi-structured interviews, which in turn were processed using qualitative content analysis.Results: The perceived foot function is today varied in terms of mobility, strength and pain according to the participants. They feel difference in their everyday life in comparison with before the injury. It appears that participants have avoidance behavior when it comes to the situation of injury.
Att tala och att komma till tals : En undersökning om vilka som kom till tals i 1940 års skolutredning
The purpose of this study is to examine who were given the opportunity to express their opinions in the government proposition concerning the future of the school system ? particularly regarding the proposal that pupils do compulsory military service - submitted to the Swedish parliament 21 March 1941. Our focus is mainly on three parts of the proposition: the proposal to introduce shooting- and grenade practice for all pupils, the proposal to introduce an obligatory military leadership training course for teachers and the proposal to introduce an obligatory summer camp for all pupils.Using primarily a qualitative method we examine how different opinions and views are expressed in the statements and utterances responding to the pending proposition and who the responders are. We will attempt to clarify who were considered to be undisputed authorities and experts, and whose opinions, for that reason, carried a lot of weight in the decision making process, comparing them to the statements and utterances submitted on a voluntary basis by non-experts. And finally, to what extent the opinions in the statements and utterances were allowed to guide the propositional work.Results show that the statements and utterances were submitted by authorities, chapter, county administrative boards and religious, non-profit and political organizations as well as different types of schools, representatives from the Board of Education and elementary school boards not a part of county councils or other types of associations.
"Jag förstod ingenting" : En kvalitativ studie om sex ungdomars upplevelser av att ha dyslexi i grundskolan
One of the most important goals of school is to teach children how to read and write. But there are also children with great problems in reading and writing/dyslexia at school. In the Swedish School Plan you can, for example, read that one of the school?s most important goals is to give these children with special needs the help that they need.This study will investigate how six young people with reading and writing problems/dyslexia experienced the first nine years at school. There has been very little research regarding students´ experiences of having reading and writing problems/dyslexia early in school, which is strange because school is a place where children spend most of their time.
Jakten på de optimala lösningarna : En vetenskaplig essä om förskollärarens ansvar och yrkesetik
Swedish childcare has undergone radical changes in the last 15 to 20 years. It has evolved from kindergarten to pre-school, in other words, gone from simple childcare to an active learning environment with the child as the center. Official documents, such as the pre-school curriculum and other guide documents, define the role and work ethics of the pre-school teacher. In my thesis I argue that it is essential to have an ongoing and continuous discussion at pre-schools on the practical applications of these frameworks and ambitious goals.What do you do when you simply cannot give every child the individual time they should have according to rules and regulations? How do you stay an active and present pedagogue in today?s pre-school with large classes and heavy workloads? How do you establish a common professional work ethics within a pre-school so that all children are treated equally? In my scientific essay, I examine these issues based on a real-life situation: Ellen in the hallway.A pedagogue must continuously make balanced decisions based on rules and regulations, on life- and work experience which, in many cases, contradict each other.
Inte som alla andra! : En kvalitativ studie om hur elever med ADHD upplever sin skolgång
Background: In the schools today it is common that teachers talk about children with special needs and children with ?Attention Deficit Hyperactivity Disorder? ? ADHD. You can often hear people discuss about children with ADHD from the teachers point of view, that pupils are hard to handle and that they do not know how to create a good relationship with them. But you seldom hear anyone talk about school from the children?s perspective, how they feel, think and experience their school attendance. Purpose: The purpose of this qualitative study was to examine how a functional disability like ADHD can effect a childs schooling and also to show how pupils with ADHD themselves experience their school attendance and how they are being treated by teachers and other pupils.Method: In order to investigate this, five interviews was carried out with students in the the ages of 16-25.
