Planteringsförbandets inverkan på bestånd av contortatall (Pinus contorta var. latifolia) med avseende på volymtillväxt och virkesegenskaper
At the beginning of the 1970´s forestry feared an imbalance in the future wood supply. Because of this anticipated "timber slump" forest companies undertook a variety of measures to counter this. One of these measures was the introduction of exotic tree species. The choice finally ended up with lodgepole pines which were considered a fast growing tree species compared to our native tree species. Theambition for the new lodgepole pine stands were to run these with rotation periods of between 40-60 years, thus smoothing out the ?timber slump? that was anticipated.
Dubbskador på Alvestakubb
Mechanical harvesting may result in timber damages leading to reduced saw log quality. The initiator of this study was VIDA ? a privately owned concern operating in the value-adding process industry of forest raw materials. The aim of this study was to examine the type and amount of damages on Alvestakubb caused by the harvester head during the cutting process. The aim was also to compare the damages caused by different types of feed rollers and to evaluate the effects of temperature on damage occurrence.
Varför En Reformerad Gymnasieskola 2011? : En reformanalys utifrån rektorer och lärares uppfattningar ? kopplat till John Deweys teorier.
This empirical work and base has been to analyze the government?s investigation (SOU 2008:27): the future road ? a reformed high school, which led to the high school reform that the Swedish government introduced as proposition (2008/09:199) about: Higher demand and quality within the high school. Skolverket (part of the Swedish government) has worked with the development of this steering document within their own mission Gy2011 in connection with the high schools during the transition. The reform comes into effect 1 of July 2011. This led to the main purpose to ask questions what high school principals and teachers think of the reform and to what extent it effects the high school programs, the examination system, what impact they see on the individual and the demand from society, and to some extent what the respondent´s answers about the government?s definition of what the higher demand and quality in the reform signify.
Installation av magnetiseringsutrustning för bränsle på en dieselgenerator : Kan det sänka bränsleförbrukning och emissioner?
Denna studie avser att ta reda på om någon förändrad effekt kan fås gällande bränsleförbrukning och emissioner då dieselolja strömmar igenom ett magnetiskt fält innan det förbränns i en dieselmotor som driver en generator. Utrustningen som ger upphov till magnetfältet har tillhandahållits av ett kommersiellt företag. Studien består av två delar, en teoretisk del och en praktisk del. I den teoretiska delen presenteras tidigare vetenskapliga studier inom ämnet samt hur tillverkaren av utrustningen menar att tekniken fungerar. I den praktiska delen har tester gällande rökgasemissioner och bränsleförbrukning gjorts.
Kromatinstabilitet som grund för kvalitetsbedömning av hingstsperma :
This study is part of a project to evaluate and develop metods to control the semen quality in stallions. The study was carried out in cooperation between SLU and Flyinge AB. The objective of the study was to analyse
-if there are individual differences in sperm chromatin integrety between different stallions
-if there is a correlation between subjectively evaluated sperm motility and sperm chromatin integrity
-if sperm chromatin integrity is changed after selection of the semen with a centrifugation method through the silica-spheres, gradient or a single-layer, i.e to use the chromatin integrity analysis as a method to evaluate the selection method.
The use of chilled transported semen has increased a lot during the last 10 years, especially among the Swedish warmblood breed. Because the foaling percentage has decreased with the increased use of chilled transported semen, there is a need to develop methods to control the sperm quality. Evaluation of the chromatin integrity could be one way to evaluate the quality of the semen.
Chromatin is the DNA in the nucleus of the sperm.
Analysis of Quality of Service of Wireless LAN for IEEE 802.11e
Nowadays Wireless LAN is playing a more and more important role in network systems. After 1999, in which the IEEE organization published its Wireless Local Network standard 802.11[1], many people saw the advantages of the standard but also the lack of support for multimedia streaming. A lot of research work has been done on the proposed IEEE 802.11e standard draft during the past 4 years. It is supposed to be able to fully support Quality of Service. The final version will be published early in 2004.
Möbelbranschen - hur små företag kan överleva på den svenska marknaden
The furniture retail industry in Sweden has gone trough large changes during the last decades. Today the industry is tough and in the maturity stage where few new companies enter, especially if they do not have a unique offer. The furniture companies have become larger and fewer, the changes have lead to difficulties for smaller and medium sized companies to grow and be profitable.Our purpose is to analyse, evaluate and compare three smaller companies in Stockholm with the intention to find what kind of marketing strategies they are using to survive on the Swedish market. First we interviewed the three companies to see what they do to survive on the market, then we asked 100 persons to fill in a questionnaire to see if they had the same opinion as the companies described.With help from theories we prepared questions which laid the foundation to the empirical part of the essay.The result from this study shows that the three companies differ from each other when it comes to using relationship marketing and placing the customer in the centre. All of them are aware of the importance of doing so, but because of different limits and possibilities they can not fully adjust everything to the customer.
Att identifiera smärta hos personer med demenssjukdom : En litteraturstudie i omvårdnad
Background: Pain can be a constant problem in many older people's daily life, associated with particular physical and social disability, depression and poor quality of life. Dementia diseases are often associated with old age. Communication difficulties are one of the consequences of the disease, which clarifies the role of nursing staff in detecting and assessing pain. Objective: The aim was to compile knowledge about how nursing staff can identify pain in people with dementia. Method: A systematic literature review, where data were collected through manual and database searches.
Förslitning av fräsverktyg
Sweden is dependent on secure sea transport. Shorter disruption of imports of fuel and crude oil can be managed with an emergency stock, but a prolonged halt in imports creates problems. For industry, the vulnerability is greater. Fragmented production chains in combination with expenditure reductions in inventory causes a dependency on proper transport of intermediate goods in the manufacturing industry. A lengthy disruption thus involves disruption of production for both domestic consumption and for export goods containing imported parts.In order to secure shipping routes with a limited number of vessels, Mine Counter Measures (MCM) capacity is required, and according to the Armed Forces, developed with new sensors and autonomous vehicles.
Yoga; spiritual balance of contemporary consumers
This research study constitutes a critical stand, which departure from the increase in welfare, and decrease in quality of life, and is further directed to the sphere of consumption. Contemporary consumers appear to seek for components to construct their self with through consumption, consumerism has become a sphere of life, and has consequently also become a victimizing force steering the identity and self construction of consumers. The alarm bells however are echoing in Western society, and consumers are experiencing dilemmas such as fragmentation, powerlessness, uncertainty and meaninglessness.In this respect we have presented spiritualism as an applicable path of escape or alternative to the scheme of the material oriented consumption sphere. We intend to broaden the scope of the interplay between spiritualism and consumerism in the act of yoga, and we have therefore been researching: what yoga is doing to consumers, and what consumers are doing to yoga. The study is based on an existential epistemology paradigm, which emphasis on the meaning of the yoga experience attained from the subjects of research; the yoga practitioners, and therefore we have carried out three focus group discussions.
Förskolechefens ledarskap : En studie om fem förskolechefers syn på sitt ledarskap
The purpose of this study was to examine how five preschool managers are looking at theirleadership and what difficulties they see in their leading. To live up to my purpose I askedthe following research questions: Which parts in their mission do the five preschoolmanagers see as problematic in relation to the curriculum for preschool and the schoolsinspectorate quality investigation? How do the preschool managers describe their leader styleand leader ideals, and is their any difference between the two of them?The method of this study was qualitative interviews with five preschool managers. Theresults that I found was that the most of the preschool managers see their leadership as coproduced(like in Ludvigssons research 2009) with the teachers and that the preschoolmanagers often find other difficulties in their mission compare to the quality investigation(School inspectorate 2012). I also found that three of the five preschool managers thoughtthat they weren?t present enough in the preschools because of their many tasks.When I tried to classify the preschool managers leader style I found that they vary betweendemocratic and authoritarian leader style in decision-making like in Tennenbaum andSchmidt?s (1973, p.
Tonala skillnader i Ostindisk jakaranda och Europeisk lönn
This graduation paper is based on my interest for wood and its different tonal quality?s.After some time of thinking I decided to write my paper on the tonal difference between two of the most common woods in guitars, East Indian Rosewood and European Maple. I had built two identical guitars before my graduation paper in which the difference was the wood the back and sides were made of. One was being made of East Indian Rosewood and the other being made of European Maple.I chose to speak with a number of people with different angle of approach to the two kinds of wood and its tonal difference and quality?s.

Signalist? Javisst!: En kvantitativ undersökning om signaleffekter av reklamframförande via ljud
The Swedish population is today exposed to more ads than ever. The number of advertising channels is growing, as well as the number of companies and their advertising expenses. As the products are becoming more alike, the harder it gets for the companies to convince the consumers their product is better than their competitors?. In order to succeed they need to understand what they communicate to the consumers through their different marketing activities, and how that affects the consumers? view of the brand and the product.
Transientanalys för Forsmark block 2 och 3 : Studie av hur val av driftpunkt och pumpreglering påverkar torrkokningsgränsvärdet
The dry out criterion (MCPR) has been calculated for the most limiting H2-events for Forsmarks unit 2 and 3, at operating points that are normally not analyzed before each cycle. The operating points that normally are regarded as the ones with the lowest margin to dry out are the ones where the thermal power is the highest at agiven recirculation flow. This report shows that this is not the case for Forsmark 3. MCPR-values at partial power operating points are higher for the limiting case inside rather than on the boundary of the region of operation. It is therefore recommended that the method for determining the dry out criterion for Forsmark 3 is revised to account for this effect.
