Effektivisering av transporter i gruvindustrin: En studie vid Boliden Mineral AB:s gruva i Kankberg
Marknaderna blir idag, oavsett industri, alltmer globala vilket bidrar till högre konkurrens. Stort fokus ligger vid optimering av produktionen för att minimera kostnaderna samtidigt som att maximera sin output. Logistik har blivit en allt viktigare del av företag vid optimering eftersom det är ett brett område med stora förbättringsmöjligheter för de flesta aktörer. Transporter är en del av logistikområdet som med högre bränslekostnader, krav på förkortade ledtider och minimala kostnader är en viktig del för företag. Boliden Mineral AB, som studien utförts hos, är ett företag inom gruvindustrin som sedan 1924 varit aktivt med säte i Boliden strax utanför Skellefteå.
Mätning av träddelar och flis på Dåvamyran, Umeå energi :
The moisture content in 10 deliveries of tree parts and 10 deliveries of wood residues were measured with different methods to analyze the quality of procedure used at Dåvamyran today. At the same time a survey was made on the measure procedures used at heating plants in Sweden
The majority of the heating plants in Sweden use weight and moisture content as base for payment but at some plants only volume. The moisture content is usually estimated by drying wood chips in an oven but few plants a visual estimation is used. At few plants moisture content is estimated spectroscopicily. The techniques using near infra read light and other electromagnetic are still at a test stage.
The methods of measurement used today are quit unreliable for the individual deliveries and there is a risk for systematic mistakes.
Kortsiktig fosforeffekt av avloppsslam : krukförsök i växthus där järn-, aluminium- respektive kalkfällt slam använts som fosforgödselmedel
The short term effect of phosphorus in sewage sludge was investigated to establish howmuch of this a farmer can grant him- or herself, if using sewage sludge as a phosphorusfertilizer. Possible differences in plant availability between sludge phosphorus precipitatedby iron, aluminum or calcium integrations were studied in a sandy soil at two pH levels.The sludges were analyzed using pot and incubation trials. As the intention was to investigategrowth limitation due to phosphorus deficiency, a soil with low phosphorus supplywas chosen as well as a low phosphorus application rate. Sludge corresponding to 12kg phosphorus per hectare was applied. Treatments fertilized by sludge were compared totreatments where 0, 6 and 12 kg phosphorus per hectare from mineral fertilizer was applied.Every treatment was replicated six times.
En formalisering av matematiken i svensk gymnasieundervisning
This study examines how formal mathematics can be taught in the Swedish secondary school with its new curriculum for mathematics. The study examines what a teaching material in formal mathematics corresponding to the initial content of the course Mathematics 1c could look like, and whether formal mathematics can be taught to high school students.The survey was conducted with second year students from the science programme. The majority of these students studied the course Mathematics D. The students described themselves as not being motivated towards mathematics.The results show that the content of the curriculum can be presented with formal mathematics. This both in terms of requirements for content and students being able to comprehend this content.
Aggregatstabilitet, jordbearbetning och fosforförluster i ett typområde på jordbruksmark :
Large amounts of phosphorus (P) are lost from the arable land due to water erosion. Both phosphorus attached to particles and dissolved phosphorus (mainly phosphate) are transported away with drainage-water and surface runoff. Good soil structure is important in minimizing these losses.
In this study, soils from 50 fields were analysed with respect to aggregate stability as measured by dispersion of clay together with the content of total phosphorus (TotP), particulate phosphorus (PP) and phosphate phosphorus (PO4P) in the water phase. All soils were clay soils with clay content varying between 21 and 54%.

Lättlösliga kolhydrater i vallfoder och i hästens grovtarm :
The purpose of this study was to investigate how the content of glucose, fructose, sucrose and fructan (WSC) varied in silage, haylage and hay harvested from the same field and at the same time of harvest. The study also investigated if differences in the WSC-fraction in the forages caused differences in composition of WSC in the colon of horses fed the forages. Hay, haylage and silage were harvested in the first week of June 2005 and stored for about nine months before feeding. Horses that were fistulated in right ventral colon and caecum were used, but only the colon fistula was used for sampling.
The fresh crop and the conserved hay, haylage and silage were analyzed for chemical composition and WSC-fraction.
Kan en lockande och informativ webbplats marknadsföra ett bibliotek? Tankar om webbplatsens roll i stadsbiblioteks marknadsföring
The web sites of libraries are to a large extent their public face and to help market their services, the web sites must have interesting and regularly renewed content. They must also be visually attractive and easily used, and thus be well structured and have a well functioning navigational system. The web masters' awareness of the ability of web sites to attract users to the site and also to the library, as well as their knowledge of suitable content and site construction, is crucial for how successful the web site actually is at marketing the library. The research question is: How do the studied web sites function as marketing sources and service providers for the libraries, and are the web masters aware of the importance of the web site? The purpose is to investigate how the library personnel looks upon the web site as a possible way to increase the popularity of the library among the public, and to study the construction and content of the library web sites to find out how well these serve their purpose.

Fuktkvotens inverkan på oljeupptag och pigmentinträngning i tall (Pinus sylvestris L.) och gran (Picea abies L. Karst) vid impregnering med Linotechmetoden :
Wood has always been an important material for people, and it is used for many applications. As for example, fuel for cooking and heating houses, construction materials and for constructing means of transport. Since wood also is a material that with time biologically degrades due to activity by micro organisms and wood fungi it is important to find ways to protect and further lengthen the life span of the material when in service. One method is to decrease the amount of water in the material by impregnation with an hydrophobic oil. The Linotech method which uses only pure linseed oil is one such possible method.
The aim of this study was to investigate the possibility to at the same time impregnate and stain/colour wood samples of pine and spruce by using the Linotech method.
