Effects of storage time, die channel length and moisture content on pellet quality of lodgepole pine (Pinus contorta Dougl. var. latifolia)

The use of renewable resources is rapidly increasing in Sweden, especially the use of fuel pellets. Through pelletizing the energy content per volume unit is greatly increased and the pellets are more homogeneous with regard to moisture content, particle size and density compared to unrefined fuels like forest residues and chips. For further development of the Swedish pellet industry, the use of different assortments from lodgepole pine (Pinus contorta Dougl. var. latifolia) is of particular interest, mainly because of its high volume production.

Om fototextpoesi : Läsningar av mötet mellan fotografisk bild och poetisk text

What is the relation of image and word, of sentences and pictures? What kind of message does this combination produce when juxtaposed on a single material plane? And how do we read its ?infinite? relation? These are the questions at the center of this inquiry. My main interest concerns the exact nature of the relation between photographic images and textual elements of poetic language when these are juxtaposed in what I call Phototext poetry.The thesis calls into question the conventional reading habits of the conjunction of photographs and texts, and seeks to understand the more complex connections intrinsic to the relation image/word and its material and perceptual play in poetic works. Does a text always ?anchor? the multiple meanings of an image, as Roland Barthes argues? What if the alterations of an image could ?anchor? certain fractions of a poetic, polysemantic textual construct? Is a photograph indifferent to the visual, material permutations of texts that certain contemporary poetic practices produce?I discuss phototextual works and collaborations of various kinds, from Molin fontän [?Molin?s fountain?] (1866) over classic surrealist poetry to language-oriented writing.

Utveckling och tillämpning av en GIS-baserad hydrologisk modell

A distributed hydrological rainfall-runoff model has been developed using a GIS integrated with a dynamic programming module (PCRaster). The model has been developed within the framework of the EU-project TWINBAS at IVL Swedish Environmental Research Institute, and is intended for use in WATSHMAN ? a tool for watershed management developed at IVL. The model simulates runoff from a catchment based on daily mean values of temperature and precipitation. The GIS input data consist of maps with soil type, land-use, lakes, rivers and a digital elevation model.

Intuberingsmetoder och alternativa metoder att tillföra inhalationsanestetika för allmän anestesi på kanin

Handling of animals during anaesthesia is an important field in the profession as a veterinary nurse and in which intubation is an essential part. Hence, adequate knowledge is necessary for the welfare of the animal. The objective of this literature study was to make it useful and trustworthy for veterinary nurses. It is intended to describe and summarize existing scientificity with its benefits and disadvantages within the different areas of intubation techniques and alternative methods of inhalation anaesthetic supplementation for general anaesthesia in rabbits. Endotracheal intubation in rabbits can be complicated and technically demanding due to the anatomy of the oropharynx including the narrowness of this structure, a relatively large tongue, large incisors and a limited mobility of the temperomandibular joint. The obstructed visualization of larynx and the rabbit?s tendency to develop laryngospasm contributes to the difficulty of intubation. Rabbits are susceptible to tracheal injury and multiple intubation attempts can cause tracheal lesions due to repeated damage to the tracheal mucous membrane, although damage can occur after a single intubation attempt as well. An ETT (endotracheal tube) with or without a cuff can be used during orotracheal intubation in rabbits.

Kvalitativ analys av Holmen Skogs internprissättningsmodell :

Transfer pricing has attracted considerable interest among tax authorities in recent years. One of the reasons for this is that various countries have now begun to protect their own tax bases to a greater extent than they did in the past. Sweden has introduced a law on the documentation on the grounds that the tax office to review the pricing of transactions that occur within multinational corporations. The purpose of the law is that companies should apply a transfer pricing that meet arm's length principle, which means that internal pricing reflects market prices. The EU Commission has, together with the EU member states formed a Forum, the EU Joint Transfer Pricing Forum (JTPF), since cross-border trade within groups constitute a threat to the internal market. The Forum has drawn up a code of conduct which includes a model of documentation.

Utvärdering av kalkstens egenskaper med laboratorie- och fältmetoder.

A pavement construction designed to cope with the different type of traffic loads; it is exposed to and at the same time it can resist the effect of the climate. A road structure consists of sub- and superstructure which is divided by a boundary known as terrace. During the construction of unbound layers (base course and sub-base course) in the superstructure, it is always ensured that the material meet the requirements for bearing capacity and the degree of compaction. These parameters are controlled by various laboratory tests and control methods. To obtain increased knowledge of the material and improve the quality of the compaction in the field, it is necessary to perform laboratory tests in order to determine material properties.A base course material 0/ 32 mm limestone from Gotland (Hejdeby) was investigated in this study.

Inhysningssystem för kalvar och ungdjur i större besättningar :

In Sweden, there has been a continuous increase in the volume of housing construction for dairy cattle. Since 2004, the number of new, rebuilt and extended dairy cow houses undergoing preliminary inspection by the authorities has grown. The livestock farms have mostly focused on cow units instead of calf and heifer sheds; which has led to a need for information in this area. The purpose of the study was to improve advisors? knowledge about bovine building construction and function; to enable them to provide more qualified advice to conventional and organic milk producers who sustain larger herds.

Indelning av trakter inför gallring på Holmen Skog : en utvärdering av svårigheter och möjligheter

A common goal in practical forest management is to maximize the yield, measured in economical terms. When a forest stand is thinned a so called inoptimality loss can arise due to non-optimal decisions. This means that the selected management schedule results in a lower net present value than the optimal one which lowers the profitability for the forest owner. Holmen Skog uses the term tract which means an aggregation of stands made before a management action. A tract should be delineated in different tract parts in connection with pre-thinning planning if there is different bearing capacity within the tract, different thinning grades should be used or if the tract contains a weaker part that should not be thinned.

Resource planning for internal logistics : A tool designed for the material handling department at Scania Axles and Gearboxes

This master thesis is performed at Scania Axles and Gearboxes, a production plant located in Södertälje. Within the plant axles, gearboxes as well as central gears are assembled from components to finished products. All production is conducted on production lines, with a pre-determined rate, which is supplied with components by the material handling department. Since the production quantity and the mix of product variants produced on the production line is customer order-based, the number and type of components needed for production as well as appropriate staffing within the material handling department is difficult to predict. Scania is currently using a number of different resource planning tools for each material handling-department within Axles and Gearboxes to visualize the workload within the departments.

Energieffektivisering av Åhlénshuset i Umeå : Utredning av åtgärder för ventilation, värme och kyla

Sweden is a country that has made some progress in developing energy efficient solutions. The problem in Sweden is that many houses and apartment buildings are old and have inefficient ventilation- and heating systems. This energy is lost when systems are inefficient, which then results in huge economic costs. Luckily, more and more people are becoming aware of this, which means that Sweden is on track to become even better within energy efficiency.Energy use for the housing- and service sector amounts to 166 TWh of total use at 616 TWh. Without distribution and conversion losses, these figures show that the housing- and service sector accounts for almost 40 % of the country's total energy consumption.

Kan biologisk mångfald ökas i ett avsatt skogsområde? : skötselplan för Storskogsberget på Holmen skogs marker, distrikt Umeå

The biodiversity of the Swedish forest has degenerated since the beginning of the 19th century when fire suppression and large scale logging first occurred. Together with a changed land use, these actions today have had a negative influence on many forest dwelling species, due to gradual reduction of natural processes, successions and different structures from the forest ecosystem. The Swedish Forest Act, together with different environment certifications, have today encouraged private persons and forest companies, among them Holmen Skog, to work actively to improve nature conservation. The aim of this study was to, by field inventories of already existing nature values, literature studies, recommendations from scientific reports and ecological gap analysis as a basis, make a management plan, for a non-production area, to conserve or improve the prerequisites for biodiversity. ?Storskogsberget? is located in the coastal area of Västerbotten County, 35 km from the city of Umeå.

Subventioner och hyresrätter? En bostadspolitisk studie

Since the early 1940s in Sweden, subsidies have been a recurring feature in housing politics.Throughout history, these have been used as a management measure to control theconstruction of housing and to promote the Swedish welfare state. The political parties aretoday disagreeing on how much responsibility the state should carry for citizens housing. Tosolve the conflict, the dwelling has to be defined. Is the dwelling to be considered a socialright, like education and healthcare or is the dwelling to be considered a product for the freemarket, driven by supply and demand?The positive population growth in Stockholm has lead to an increased demand for dwellings.The supply of dwellings has not been growing at the same rate, which has implied higherhousing prices and longer wait for rented apartments.
