Geotermisk fjärrvärme i Gunsta
Gunsta is situated about 10 km east of Uppsala. Today there are plans to establish 1000 new households in Gunsta before year 2030. The required energy for heating houses and water would be distributed via a district heating system, which also includes 200 existing residences. The annual required energy, according to this study, would be 16.2 GWh with a maximal peak effect of 6.9 MW.
To meet this need, the study suggests a system with heat pumps to upgrade the 31?C water from a 1.8 kilometre deep borehole.
Den heliga kungen och den saliga änkan : en jämförande studie av två svenska helgonlegender från medeltiden
Den heliga kungen och den saliga änkan is a comparative study of the saint legend of Erik and the saint legend of Elin as they are represented each saint?s officium. The base for these comparisons is the question of what general similarities, and differences, there are as well as an immerse investigation of how these legends portray halidom and finally how the issue of femininity and manliness are portrayed through these two legends. During the thesis apparent similarities appear in how the legends are structured; a template seems to have existed in which the content of what a legend should include is stated. Erik, as well as Elin, are of noble birth and are portrayed as godly people who live bountiful and ascetic lives.
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 ödmjukt auktoritär rådgivning : Ethos och etik hos föräldrarådgivaren Petra Krantz Lindgren
Wermland was affected by the Spanish flu like the Swedish national average, about a half percentage of Wermlands population would lose their lives to the flu during the autumn 1918. The flu has for many fallen into oblivion. This oblivion is so wide spread that it´s possible to talk about a "collective forgetfulness". The society have selected to remember 1918 for "when the guns went quiet on the western front" and not for the millions who died from the treacherous Spanish flu. The world had already suffered enough from the four years of war that had been fought, thus the victims of the flu would be honored but would soon fade in to oblivion. When you investigate deeper you get the picture that the national average don´t do Wermland and its cities or rural areas any justice when a large variations seems to occur within regional areas.

Bibliotekariers pedagogiska roll: Om konsten att lära andra att söka och använda information
There is an increasing demand for information literacy, which is mirrored in curriculum throughout the whole educational system.

Dimensionering av industrilager för biobränsle :
The aim of this study was to develop a simple model for calculating stock costs for bio fuel at Billerud Karlsborg and subsequently recommending a suitable stock level of bio fuel. The stock components considered in the model are GROT (branches and tops), bark, dry wood chips, raw wood chips from barking and sawdust. The calculations are based on a probability distribution of historical deviations between ordered and delivered volumes. The model presents two different ways to manage the supply in case of irregular deliveries. The first way is to stock enough volume to cover the deviations and the second way is to compensate with a quick purchase from the spot market (at extra high purchase prices).
Värdekedjeanalys av returflöden på Scania : Fallstudie på marknaderna i Sverige, Tyskland och Benelux
Today Scania give a high priority to the continuous improvements on the quality of their vehicles. To follow up the flaws in product quality, which are recognized by the repairs at the local workshops, material requests are carried through to be able to analyze the defects at the plant in Södertälje ? in purpose to improve the product quality. The material requests are also carried through to compensate the workshop for their expenses and to check that they are working according to the company?s warranty manual.Due to local routines and different distribution structures at the different markets the lead times and the costs caused by the flow of material are hard to estimate.
Price transmission dynamics of Chinese ADRs listed on the NYSE
Purpose: This study aims to examine the price transmission among ADRs (American Depositary Receipts) and their underlying shares, US market index and Hong Kong market index. We will attempt to capture how a shock in the home market is transmitted to the foreign (and vice versa). In addition we will attempt to assess the relative weight of each variable in the system generating unexpected variations of its own and other variables and at what speed the shocks are absorbed.Methodology: ADF unit root test, Johansen?s co-integration test, Granger causality test, VECM, impulse response, variance decomposition Empirical foundation: Five Chinese ADRs listed on the New York Stock Exchange. Each ADR represents a specific industry.
Remittera till akutmottagningen eller inte? : Sjuksköterskors uppfattning av beslutsfattandet på vård- och omsorgsboende.

Statistisk kartläggning av dimma längs E4:an mellan Helsingborg och Jönköping
Fog is a small-scale weather phenomenon that are fascinating to people. However, the presence of fog in road traffic reduces the visibility and increases the risk of road accidents. By the Swedish Road Weather Information System (VViS), the safety on roads could ameliorate and road accidents caused by fog and other weather hazards could be prevented. Fog is however a complex and usually local phenomenon, why fog formation generally is not easy to predict. For that reason, a statistical mapping of fog, especially along a motorway with high traffic volumes, could be useful in planning to prevent road accidents.
Lärare och bibliotekarie funkar det? En fenomenografisk studie av gymnasielärares uppfattningar om gymnasiebibliotekariens betydelse i undervisningen.
Resource-based learning or problem-oriented learning are teaching methods that are becoming more and more common in schools today. In order to make these teaching methods work there is a demand to make students information literate. This entails that school librarians ought to play a more important role in teaching than before since they are the ones that are the most qualified when it comes to mediating information skills. The aim of this thesis is to find out how nine teachers at six senior high schools apprehend the professional role of the school librarian and how they apprehend the conception of information literacy In order to learn about these conceptions we have chosen to study to what extent collaboration exists in the schools in question and the teachers conceptions of the importance of the school librarian in this context. We have used phenomenography which is both a set of theoretical assumptions and a methodology.

Det gör ont när stockar spricker!
The aim of this study was to provide SCA Forest Norrbotten District with material to assist in their work towards decreasing the frequency of bucking splits in their saw timber logs. SCA Forest supplies the Munksund sawmill with pine timber. Periodically the sawmill experiences problems related to bucking splits in their logs.
The purpose of this study was to find an available method to measure the occurrence of splits directly on incoming timber. The ambition was also to gain some knowledge about possible variations between different logging crews in terms of split frequency. If possible, this information could be used to investigate if certain crews produced more splits than others, and thereby making it possible to provide feedback to the logging machine operators.
The study consisted of two major parts, a literature review, and a practical sawmill study.
