Att mäta publicering av artiklar: En tillämpning av bibliometri på evidensbasering inom socialt arbete
This thesis examines the scientific publishing in the subject area of evidence based practice EBP in social work. Issues are: How has this publishing evolved, separately and compared to the publishing about evaluation in social work? What authors/countries have produced the largest numbers of articles? What journals have published the largest numbers of articles? Which are the most frequent co-occurrences of a selection of terms? 161 records for articles from 50 different journals were selected from Social Services Abstracts using subject of journal and a query as criteria. For each year, the number of articles about evaluation in social work was larger than about EBP. A decline in the publishing about evaluation coincide with a growth in EBP after the year 2000.
Vilken är den teoretiskt optimala toppdiametern på bokmassaved vid motormanuell avverkning?
The bioenergy market has been introduced relatively late in a perspective of the Swedish forestry. Nowadays branches and tops are used more frequently as bioenergy after harvesting. Therefore, it has developed a competitive situation between pulpwood and bioenergy. This situation has even established some questions. Two examples of these are:
? At what top diameter should the final piece of pulpwood be crosscut to get the best economically result?
? Should the top diameter, at the final piece of pulpwood, be crosscut at a thicker or smaller diameter than what is done today?
The purpose of this report is to answer these two questions when the harvesting is made motor manually in beech stands.
Export of wood pellets from British Columbia : a study about the production environment and international competitiveness of wood pellets from British Columbia
The global wood pellet market has seen a rapid growth after the adoption of the Kyoto protocol and the renewable energy incentives created within the European Union. The global consumption of wood pellets reached 13,5 million tonnes in 2010 and several experts estimate the consumption to be between 35-50 million tonnes by 2020. These forescasts raise the questions which regions that can supply this vast amount of wood pellets and what the conditions are for producing it.
This study evaluates the conditions for wood pellet production and export from British Columbia, on Canada?s west coast, focusing on existing industry structure, raw material supply and the distribution chain.
Högbeläggningssystem för frigående värphöns : erfarenheter 2011
The aim of this study was to evaluate whether gallop training, rather than regular drive training, is worthwhile for trotters race performance. Another aim of the study was to expand the author?s riding- and driving capacity, and get more practical experience on the impact of interval training on trotters. The sample population in the study was two trotters, one Standardbred, and one cold-blood. Given the small sample population, the results of the study is only indicative on the effects of gallop training on trotters, and not conclusive.
Konstruktion av yttervägg med vakuumisoleringspanel
This paper is about the extent to which simplified penetration calculations ofsmall-caliber projectiles is a useful tool for assessing the physical protectioncapability. The work should be seen as an attempt to create an accessible tool inthe form of a simplified equation that allows for a better and safer use of thenaval vessels. The tool will also be used at different levels so that decisions andinstructions could be clearer.Performed calculations show a very limited capacity of a ship's basic design interms of physical protection against the use of small-caliber projectiles.How do we know that the calculations correct? By verifying the calculations withpractical shooting tests, a substantial condition to answer the question will becreated. To shoot against a material with two different thicknesses estimated toproduce perforation and non-perforation is a good approximation of the equationusability in the context..
Söktjänster för akademiskt bruk. En jämförande undersökning mellan Google, Google Scholar och Scirus.
This paper is a comparing study of the retrieval effectiveness of the search engines Google, Google Scholar and Scirus. The aim is to find out how good they are at retrieving relevant academic material in the research-field of Library and Information science. The thirty search questions where based on actual information needs collected from exams within the field of Library and Information Science. This method was used to prevent that none of the search engines were given an advantage because of construction of the information needs. The first twenty retrieved documents on the retrieval lists are examined for academic content and relevance.
Ung, samtida och postmodern : En studie av det svenska konstfältet under 1980-talet utifrån Lars Nilssons konstnärskap
The aim of this thesis is to study the Swedish art field during the 1980s, from the perspective of the artistic production of Lars Nilsson. During this decade he became one of the most well known young artists associated with postmodernism.The thesis is divided into three parts, where the first part examines different influences and aspects of the art of Lars Nilsson, as well as the contexts he was a part of. This is performed through a chronological as well as a categorizing presentation, based upon different exhibitions where Nilsson participated during the 1980s.In the second part the subject is the Swedish art field, and how Lars Nilsson came to be part of a a new established category of a young generation of artists, mostly born in the 1950s, who were associated with youth, postmodernism and contemporaneousness. This part also puts attention to the importance of Lars Nittve, then art critic and curator, in introducing postmodernism, as well as establishing this new categorization of artists in Sweden.The last part of the thesis studies four different group exhibitions, and how they all exemplify how "a younger generation of artists" were to be connected with notions of postmodernism and contemporaneousness through curatorial practice. Lars Nilsson participated at the thirst three of these exhibitions.
Upprustningsmetoder för en bankropp : En jämförelse ur ett LCC-perspektiv
In recent years, the Swedish railway track system has been neglected in terms of capacity and maintenance. To adapt the existing system to current traffic load there is a great need for extensive improvement and maintenance. Shortcomings are especially occurring on older embankments running over soft subgrades. To select the most suitable method for reinforcement of the embankment, it is important to evaluate different solutions from a life cycle cost perspective. In long-term perspective, it is often shown that a method with low investment cost causes a higher maintenance cost and a shorter technical lifetime.
Den kommunala folkhälsosamordnaren söker sin arbetsroll
Coordinator of public health has recently become a new profession in the field of Health Promotion. During the last few years the pedagogic perspective has been increasingly important for the coordinators as a way of adapting their work methods to the circumstances. The conditions for coordinators of public health differ between municipalities and thus their tasks and responsibilities may vary with the local structure. According to the literature there are several ways to conduct Health Promotion and it is in the hands of the coordinator to adjust the methods to fit local conditions. The purpose of the study was to examine what influences the coordinators of public health and how that affects their work methods.
Inneklimatet på ett kontor : Undersökning av inneklimatet vån. G4 stadshuset samt kontor på Ånghammargatan
This report describes an investigation of the indoor climate in two different workspaces. Since we a big part of our lives are staying indoors in artificial environments, and more particularly in our workplaces, we think it would be interesting to do this investigation. The technical solutions for air treatment systems began with simple natural systems without fans and where the thermal rise of the air applied. In modern time is technical air treating systems used to take care of the fresh air supply. This type of units can supply filtered air with the right temperature to the building. Well-functioning ventilation is essential to bring clean fresh air to the room and effectively remove impurities without sound- or draught problems. The indoor climate is relevant for the output capacity.
Ett slott i romantikens lövsal : skogsutveckling på Château du Grand Val - att utveckla en integrerad gestaltande skogsbruksplan
The work presented here aims to give the owners ofChâteau du Grand Val, Roland and Marie Nilssond?Aubigné an integrated creative forest management planin which their goals with the property is heeded, andwhere the plan is so clear that they can follow it withoutmuch difficulty.This work has come about through the normal processesof forest management plans, landscape architecturalproposals as well as through field trips, field andliterature studies, and our combined experience fromour studies. The study visits, both on location in Brittany,France, but also in other places, as for instance Högestad,has provided the background information that formedthe basis of our analysis and the proposal that is derived thereof. Some suggestions, which we consider importantto the overall impression of the property, is provided amore focused and detailed solution, while other parts,which are important but can either benefit from havingdynamics in the design process or will be adapted toadjacent sites, are developed using a more generalapproach. In some cases several possible developmentprinciples are presented.The proposal presents a detailed plan for themanagement of the forest from the experience, wildlifeand forestry economic standpoint.
Flödesmätning i vattenkraftverk : Studie av alternativa mätmetoder
Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.
Kalkningens påverkan på fosforlöslighet : skakförsök baserade på två svenska långliggande kalk- och fosforgödslingsförsök
Eutrophication is an environmental problem that affects more than ten percent of Swedish lakes. Excess nutrients increase the growth of algae, and cause major problems in the ecosystem through oxygen-free bottoms, fish kills, and at worst dead bottoms. Agriculture accounts for 44% of human emissions of phosphorus to lakes and rivers. Leaching occurs of particle bound phosphorus and of dissolved
phosphate. The amount of phosphate in the soil solution that may be leached is partly due to the prevailing pH in the soil solution.
The purpose of this study was to investigate how the relationship between phosphate solubility and pH was affected by liming.
Analys av data från flyglaserscanning :
In forestry there are always needs of forest data to make good strategic decisions of different actions and economic winning. Usually this data gets from field-estimations made by forest workers with expensive costs and sometimes unsatisfied quality.
StoraEnso Skog is a great forest company in Sweden and they have part of the responsibility of the forest own by Bergvik Skog. Bergvik Skog is owner of 1, 9 million hectares productive forest land. Both Bergvik and StoraEnso have great interest in new inventory techniques to get the important forest data.
The company Foran Remote Sensing offers the opportunity with airborne laserscanning of forest and forest land. Foran got the mission of Bergvik and StoraEnso to laser scan Bergviks possession in Älvdalen, Dalarna.
