Kraftkabelförläggning i mark : - en studie av produktionsmetoder
The assignment given to us by NCC was to compose a degree project based on ground excavations for power cables. The aim of the study was to examine suitable excavation methods depending on different possible terrain conditions. The amount of previously written material within this subject is nearly non- existent and therefore there is a genuine interest by the NCC to receive a compilation of different production methods. The greater part of this study is based upon interviews with several companies active within this area of expertise. The technique of placing the electricity grid beneath ground for safety is today getting more and more common.
Barkar det åt skogen för svenskt tidningspapper? : empirisk analys av efterfrågan och företagsstrategier på den svenska marknaden
According to Food and Agriculture Organization newsprint is defined as: Uncoated paper, unsized (or only slightly sized), containing at least 60 percent of mechanical wood pulp. The consumption of newsprint in Sweden was just over 798 000 tonnes in 2009, which represents approximately 90 kg per person. Although there are studies that predict a drastic reduction in newsprint consumption in the Western world, there seems to be a clear difference between forecasts for the future given by statistical analysis of newsprint consumption and forecasts given by experts in the industry. The former predict a continuing increase while the experts see a coming decrease in consumption.In this report, both demand and business strategies of newsprint in Sweden are studied. The study also presents a forecast of the future which is based on historical data and qualitative interviews.
Läkares användning av medicinska tidskrifter ? Är sjukhusbibliotekets bestånd en viktig källa?
The purpose of this study is to find out how and to what extent doctors use the hospital library?s collection of print and electronic medical journals. Major changes have the last years occurred in the journal collection. The journals are very costly and little is known about the user satisfaction with them. Therefore it?s important to examine how satisfied the users are with the collection and how they utilize it.
Strategier för skogsägande i svenska skogsföretag :
This final thesis consists of an investigation of how suitable it is to vertically integrate forest in Swedish forest companies. Different strategies to obtain raw materials have been evaluated and the advantages and disadvantages have been weighted against each other.
The investigations contain a number of interviews with represents from companies with different strategies and persons that in different ways have faced the question of issue. An account study of SCA´s forest ownership has also been performed.
The benefits for a forest company to vertical integrate forest consist mainly of safety in delivery, control over the supply chain and company image.
Identifiering av konfliktbestånd med hjälp av laserskanning
The interest in harvesting wood fuel in conflict stands has grown in recent years as a consequence of the increased demand for biofuel. Conflict stands are young forests that have not been cleaned and have a large number of stems ha-1with a great height and diameter distribution. This means that traditional field measurements in conflict stands are difficult and very time consuming. Therefore, the forestry sector is in need of new, more efficient inventory methods. In this study, the Lidar data from Lantmäteriet?s (the Swedish mapping, cadastral and land registration authorities) new national height model was used in combination with plots from the Swedish national forest inventory from 2009 to create functions for; height, volume, diameter and number of stems.
Hur bör en modern livsmedelsleverantör arbeta för att säkra sin position på marknaden? - en studie av det Svenska kommersiella restaurangsegmentet
Målet med denna studie är att utreda hur olika egenskaper hos leverantören prioriteras och värderas av den inköpsansvariga. Det är betydelsefullt för restaurangbranschens säljorganisationer att känna till på vilka grunder en restaurang fattar sina inköpsbeslut och hur man resonerar vid val av leverantör. Studien genererade ett antal variabler vilka livsmedelsleverantören bör studera och utvärdera, däribland varumärket, service, sortiment, kvalitet, pris, leveranssäkerhet m.fl. Men också identifierades ett antal strategier och arbetsområden vilka leverantören bör ta hänsyn till. Total Supply är ett koncept vilket respondenterna visade ett behov och önskan för.
Bestämning av jordmodul för kringfyllnadsmaterial runt rörbroar
Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

Vad vill vi med vårt skolbibliotek? En undersökning av attityder till skolbiblioteket bland skolledare och lärare
The purpose of this study is to examine teachers and school-leaders attitude to the school library. Both the cause of and the consequences of these attitudes are examined. In order to fulfil my purpose I have examined this through both literature and empirical studies. I have interviewed the headmaster, the school librarian and two teachers at two comprehensive schools. As theoretical framework I have used David Loertschers taxonomy containing theories about the levels in an ideal school library and Miles model of school development.
Vård av kanin med gastrointestinal sjukdom
This work is intended primarily for animal nurses/veterinary technicians and describe parts of the rabbits digestive tract, causes of gastrointestinal disease, symptoms, diagnosis, general care of rabbits with gastrointestinal disease and how to prevent that gastrointestinal illness occur. The work is largely based on literature studies but also on a questionnaire sent out to rabbit owners to get answers on how they generally hold and care of rabbits, which gastrointestinal diseases that are most common, how owners care for their animals at home during illness and to examine if the owners think that the knowledge of this subject is good at his veterinarian/clinic.The purpose of this work is to improve the skills of animal nurses but also to improve the skills of owners through competent advice from animal nurses.The result show that gastrointestinal disease often is caused due to improper feeding and care of rabbits and therefore is advices from animal nurses an important part of preventive care. Animal nurses are also an important part of treatment of rabbits with gastrointestinal disease when supportive care as fluid therapy, supportive feeding and supply of a stress free environment is important for the animals to recover..
Effekter av gödsling i äldre tallbestånd på renbetesväxter i fält- och bottenskikt :
Reindeer husbandry and Forestry are both area related industries and will in big extent use the same lands. Conflicts often arise because of that the industries have different interests. Many of the activities done by the forestry influences the reindeer husbandry in an undesirable way, simultaneously as the reindeer husbandry activities can have negative consequences for the forestry. One such forestry activity is fertilization.
It was during the 1960´s forest fertilization began to be practiced and the reason was that the increase in growth that the fertilization gave could be able to cover for the future shortage in wood many feared.
During the 1970´s when the fertilizing activities were most intensive about 200 000 ha was fertilized annually.
Minskad trädtillväxt under Lilla sitiden? : En dendroklimatologisk jämförelse mellan nutid och 1600-talet invid trädgränsen i norra Skandinavien
During the period called Little Ice Age (1400 ~ 1900) the climate of northern Europe was in an annual year-basis overall colder than it was before and after that period. The numbers of short, cold and rainy summers and long, bitter-cold winters where often repetitive under the approximately 500-years the period lasted. In Scandinavia, the coldest time during this period is estimated to have started around the end of the 16th century and lasted to the beginning of the 18th century. Trees growing at the tree-line are limited by temperature for their annual growth and hence showing differences of growth during changes in the climate, a method called dendroclimatology. The variations of growth can be read in the tree-rings either by analyze the width of the ring or by look into the density of the wood and is used to reconstruct past climates.
Flerskiktat papper : en sammanställning av historia, teknik och forskningsresultat
Until the beginning of the 1900:th century the paper making process was handicraft. The paper machines that have been developed since then are as impressing in size as fascinating when it comes to the technique. The process has always been improved to give a better paper for lower costs, with as short manufacture time as possible. Stratified forming has been a reality since 1830. From the beginning it was applied to board and paperboard.
