Productivity of integrated harvesting of pulpwood and energy wood in first commercial thinnings
The aim of this study was to quantify the productivity and the costs of different harvesting systems (teams), containing harvesters equipped with accumulating harvester heads and forwarders, in first commercial thinnings were an integrated harvest of pulpwood and energy wood were performed. In the beginning the plan was to study and measure 20 sites before and after harvest. Due to storms during the summer of 2010, complete data could only be obtained from 8 of these 20 sites. Seven of these sites were privately owned and one was owned by UPM, all of the sites had been pre-commercially thinned. The mean stem density before harvest was 2578 stems per ha and the mean stem volume was 0.074 m3solid over bark.On average 1518 stems/ha was harvested.
Hallsta Pappersbruks virkesförsörjning
Competition of spruce fiber raw materials has increased dramatically in the last few years, leading to the fact that transportation costs in the current situation represents a much larger share of the total raw material cost. The Holmen-owned pulp industry Hallsta Paper Mill's location on the coast also constitutes a problem, because of the lack of raw material, which is much larger there, than for a pulp mill located in the hinterland. For a coastal industry it?s therefore natural to import much of the raw material by boat or to buy it from the timber terminals, in order to maintain good profitability. The purpose of this study was to analyze how the size of Hallsta Paper Mill timber supply area, without competition, with competition and with terminal use, affects the company ?s transport costs.
Om folk levde och tänkte fritt och agerade från sitt hjärta så är risken att allt skulle gå åt helvete : En studie om PR-byrån Studio Total som orsakat ett totalt samhällskaos
Studien analyserar den svenska PR-byrån Studio Total, som använder sig av gerillamarknadsföringsmetoder för att synas i den svenska mediala debatten. Företaget har fått stort genomslag genom att delvis utföra fiktiva reklamkampanjer som svenska folket och omvärlden har tagit del av. Konceptet av att marknadsföra produkter och värderingar genom nyhetsjournalistiken har inneburit att allmänheten känt sig vilseledda. Studio Total har även klivit in på en politiska arena där de kontroversiella kampanjerna har blivit kritiskt ifrågasatta och negativt mottagna. Studien försöker förklara om en PR-byrå kan verka inom en kommersiell och ideell marknad.En kvalitativ intervju har utförts med en av Studio Totals grundare och en kvantitativ enkätundersökning gjordes för att erhålla mediestudenters attityder till företaget.
Timeliness cost for agricultural sprayers : weed control in cereal crops
Evaluation of machinery costs is necessary for selecting appropriate farm machinery. Timeliness cost due to untimely operations is an important component of machinery costs. Timeliness costs can be high for crop sprayers, since pesticide application must be carried out within a short time interval. This Master thesis investigated the timeliness cost and the probability of a suitable workday for spraying. Timeliness factors were estimated for four different crops (oats, spring wheat, winter wheat and barley) using historical weed trial data.
Hur påverkas elefterfrågan i svensk cellulosaindustri av oljeprisförändringar?
I uppsatsen undersöktes hur elefterfrågan i svensk cellulosaindustri, med en given uppsättning produktionsfaktorer, påverkades av förändrade totalpriser på tyngre eldningsoljor. Partiella kortsiktiga och långsiktiga egenpris- och korspriselasticiteter skattades utifrån årliga tidseriedata mellan 1970 och 1998 från SCB och Energimyndigheten över elförbrukning och totala el- och oljepriser. Skattningen utfördes med hjälp av OLS och en dynamisk loglinjär efterfrågemodell för dels total elefterfrågan, dels efterfrågan på externproducerad el för given total elefterfrågan. Ekonomiska motiv kan förklara de flesta signifikanta skattningarnas tecknen och värden samt vissa skattningars insignifikans, varför använd modell och skattningsmetod tillfredsställande stödjer slutsatserna: total elefterfrågan påverkas obetydligt av oljeprisförändringar: kort- och långsiktig efterfrågan på externproducerad el påverkas betydligt mer - en procents höjning av totala oljepriset ökar kortsiktigt efterfrågan på externproducerad el med 0,13 procent. Höjda miljöskatter leder därmed till ökad efterfrågan på externproducerad el som, om genererad på ett miljöfarligt sätt, kan motverka miljöskattens syfte globalt sett.
Olika kommuner: olika eftervård? En jämförande studie av hur tre kommuner definierar och arbetar med eftervård efter LVM.
Aftercare is an important condition for the Care of Alcoholics and Drug Abuse Act (LVM) to be successful. According to the law, the municipals are responsible for the aftercare. We compared how three municipal in Skåne, Sweden, define and work with the aftercare after treatment under LVM. The study was based on nine qualitative interviews with social workers, division managers and politicians from each municipal. As a theoretical reference the theory of total institutions and empowerment theory were used.
Konvertering från direktverkande el i kommersiella lokaler : Ekonomisk och hållbar utveckling
Buildings worldwide account for 40 % of the total energy use. Climate change is of increasing importance, but few are willing to reduce their standard of living or get a higher cost for the change. Energy efficiency of existing buildings gives the greatest benefit economically and environmentally. The real estate company Klövern AB manages 46 properties in Karlstad. Heating is the major cost of the total operating costs of real estate. Rising energy prices increase the need for Klövern AB to improve energy efficiency and to investigate alternative sources of heat.
Vem väljer att bli bibliotekarie? : en studie över bibliotekariestudenter i Borås
This paper will portray the differences and similarities that exist between students whoattended the Swedish School of Library and Information Science in Borås.The study is based upon quantitative information gathered from a survey which wasdistributed to first-year students in Borås in the auturnn term 1994. A total of 77 studentsresponded to the survey.We also do a comparative study of the students at all the library programs in Sweden.This is partially based on the findings by a thesis prior to this one by the authorsSvalstedt and Österdahl.We found that the students in Borås differ mainly in their personal histories and backgrounds.When it comes to their attitudes towards the profession and educationalmatters they are similar. Further we found the same to be true in our comparison of thelibrary programs in total..

Karakterisering och klassificering av gotländska ytvatten enligt ramdirektivet för vatten
In this study the practical work with the EU Water Framework starts on the island of Gotland. 33 lakes and 32 streams have been characterized and classified regarding to their ecological status. The aim with the characterisation is to create a uniform discription of all waterbodies and a comparable estimation for the future. The aim with the classification is both to study the waterbodies ecological status and to gain knowledge of where the resources should be concentrated so that the ecological status in all waterbodies will be good in 2015.The characterisation has been done according to the EU Water Framework Directive, and the factors that have been applied are the mean depth and area of the lake. The length and size on the catchment area are the factors that have been used on streams.
Energieffektivisering av Villor : Finns möjligheten till Passivhusstandard för befintliga bostäder
The climate change the earth today has to face is no longer a global problem when every individual has a responsibility to act. The residents in Sweden have no understanding how their energy consumption affects the environment, nor what measures can be taken to reduce the energy consumption.The use of the energy in new Buildings is considerably lower than in the older ones as conditions have improved and the requirements have been more stringent. As most of the buildings in the future have already been constructed it´s important to take every opportunity for energy efficiency and rebuilding of available buildings will become a significant act. Reconstruction of a building contributes generally to both a reduced individual and a reduced total energy use, while new constructions only keep a low individual energy use but a increase the total energy use. For this reason we present the opportunities for reconstruction, mainly to reach the standards for a passive house..
Vokalkvalitet och duration hos diftonger i benadiri och nordsomaliska
I beskrivningar av somaliska noteras i vissa kontexter en dialektal variation i vokalkvalitet och duration mellan sydsomaliska (benadiri) och nordsomaliska. Modersma?lstalare av somaliska bekra?ftar noterade dialektala skillnader i vokalkvalitet och duration, och anser att det finns en possessiva?ndelse pa? benadiri eey vilken skiljer sig fra?n den nordsomaliska motsvarigheten ay.Underso?kningen syftade till att ta reda pa? om och pa? vilket sa?tt vokalkvalitet och duration varierar, i diftongen ay i de somaliska dialekterna sydsomaliska (benadiri) och nordsomaliska. Studien begra?nsades till ma?tning av vokalkvalitet och duration i possessiva?ndelsen -ay.
Quantification of sleep in dairy cows in three different stages of lactation
The aim of this project was to quantify the total sleep time in modern dairy cows during24-hour periods and to investigate whether the total amount of sleep as well as timespent in different sleep stages varies between the dry period, early- and peak lactation.The distribution of sleep time between night and day was also examined. Furthermore,correlations between sleep and lying time, fluctuations in body temperature and heartbeat were included in the aim. Eight dairy cows of the Swedish Red breed were used inthis study, which was carried out between June and September 2010. In order toquantify sleep non-invasive electrophysiological recordings were performed.Simultaneously with collecting sleep data, body position and body temperature werealso recorded. No heart rate data was obtained due to difficulties of maintainingelectrodes for heart beat measurements attached to the skin.

Konstruktion och design av hjul
The task given to us was to develop an industrial wheel with new thinking in terms of fresh design and construction, with the ability to brake. While the produced wheels of today only own the property of total braking, a wish was made to integrate the ability of directional locking.The time spent working with the project has been filled with multiple sketches of ideas and function analysis.Choices of material and ways of construction have been verified by calculations, tests and prototype building. The goal of this thesis has been to develop a unique caster with well thought-out design that would be adaptable to different areas of applications.The result was a hubless wheel with the ability of directional locking before total braking.A prototype of the wheel has been made to show the design and functions..
