Beräkning av värmeenergiförluster i flerbostadshus genom analys av den totala fjärrvärmeenergianvändningen :
This thesis has been carried out on behalf of IV Produkt AB and intends to set an average ratio of thermal energy losses in apartment buildings that were built during the 1960-1990. This shall be derived by analyzing the total district energy consumption that has been divided into three parts: heat energy losses (the actual heating requirements), the heating of domestic hot water and heating energy consumption for the controlled ventilation.Three different residential areas that were built during the years 1962-1966 and one that was built in 1993 has been analyzed. All residential areas are located in Växjö urban and contains between four and six apartment buildings.The analyzed objects have a mechanical exhaust ventilation systems and district heating as the heating method. No own laboratory work or experiments have been done in this thesis, the calculations have been done on the basis of parameters from VEAB, interviews with property managers, and literature studies. By calculations, we have got a result that is reported in Chapter 6.
Utvärdering av fosforläckageefter stallgödsling med hjälp av lysimeterteknik : Evaluation of phosphorus leaching aftermanure application using lysimeter techniques
Based on laboratory studies with lysimeters, the concentrations of dissolved reactive phosphorus(DRP) and particulate phosphorus, which is the main part of other P (OVRP), has been studied inpercolating water. The experiment was conducted through irrigation of small soil columnscontaining clay topsoil from an experimental field in Västergötland. Three rain simulations wereconsecutively performed. DRP concentrations in the percolating water ranged between 0.2 - 0.3mg·Lclearly related to the phosphorus concentration in the soil, measured in a soil extract ofammonium lactate (P-AL). Concentrations of OVRP were relatively low and ranged between0.12 and 0.16 mg·Lwas not proven and the experiment may reflect how a relatively slow percolation of water mayrelease DRP.

Din, min eller vår islam? : En kritisk diskursanalys av fyra religionsläromedel för gymnasiets framställning av islam
This paper investigates the presentation of Islam in textbooks used in the study of religion in high schools. The papers focus on two main questions concerning the ways in which Islam is presented in the analysed textbooks, and how the new curriculum has influenced the portrayal of Islam in the materials. Here, the paper utilizes a method of critical discourse analysis with Faircloughs three-dimensional analysis. The paper then concludes that the presentation of Islam is negative in nature, with the content and view of Islam having been simplified and stereotyped. Often the textbooks studied frame Islam as being an aggressive and oppressive religion, especially in matters con-cerning women.
Evaluation of Different Extraction- and Analysis Methods for Calprotectin in Feces
Background Calprotectin is a protein expressed in the cytoplasm inside the neutrophile granulocytes. During inflammatory bowel disease (IBD), the neutrophile granulocytes are involved in a complex interaction at the inflammatory area where they die and release their content into the intestinal lumen. Therefore, calprotectin in stool is a suitable marker for diagnosis and measurement of the disease-activity in patients with IBD. The most commonly used method to detect calprotectin in stool is ELISA, but the process of manual preparation of stool samples is time-consuming.Aim The objective of the study was to evaluate an extraction method that could replace manual preparation of fecal samples and to compare different methods for measuring Calprotectin in stool using two ELISA-methods from two manufacturers and one rapidtest.Methods For extraction of calprotectin from stool samples we used sample collector tubes from Epitope Diagnostics and fecal preparation kits from Roche. Two different ELISA-kits for measuring calprotectin concentration in stool were compared.
Bildregistrering i teorin och praktiken: Mid-Manhattan Picture Collection och Kungliga biblioteket.
This thesis presents a comparative study of image registration at two picture collection libraries. The two registration systems are analyzed as to the theoretical principles behind them and their practical application, and related to theoretical tools for subject analysis and bibliographic standards. While a growing number of picture collections now digitize their material, generally accepted standards and methods for the registration of digital images are still lacking. Many different systems coexist, often developed in-house in response to ad hoc needs and based on traditional registration tools created for textual documents, resulting in internationally incompatible mixed-format systems. The two picture collections examined here, however, have opted for similar, standardized tools for registration and subject analysis, and while there are differences in their application and focus, they have both considered issues of cross-system compatibility.
Socialarbetares tolkning och tillämpning av LVM: ur ett genusperspektiv
The law (1988:870) concerning care of substance abusers is constructed in a way that gives the social workers room to interpret and apply the law individually. This may contribute to differences in treatment between female and male substance abusers. The purpose of the essay was to investigate whether the client's gender had any significance to how the social worker interpret and apply the law (LVM).The specific questions we worked around were:- What significance does the client's gender have in the decision-making?- Does the social worker's opinion about the law have any significance?- What factors can effect the social worker's interpretation and application of the law?- What importance do the social workers attach to prevailing norms about men and women when they interpret and apply the law?We chose to use a qualitative method to answer the above questions. Six social workers were interviewed and 39 LVM sentences were analysed.
Triage - hälsoekonomi : resursallokering och kostnadsberäkning för olika proriteringsnivåer inom akutsjukvård
When a person arrives at the emergency ward at the Uppsala University Hospital with his or her symptoms he or she explains the problems and then a priority process starts. The staff evaluate at which emergency level the patient is located in a model called Triage. The Triage model helps to decide the priority need and is based upon templates which point out in which of the 5 categories a patient is to be placed, to eliminate any future risk regarding his or her health. A lower triage level means lower priority but implies better health when the evaluation takes place. To obtain optimal effect of the Triage model the evaluation of symptoms must be reproducible so that patients with the same symptoms are placed at the same triage level regardless of whom among the staff conducts the evaluation.
The purpose of the study was to see if the resources are allocated based on priority level of the patients.

Populärkultur på fritidshemmet : Hur påverkar populärkulturen innehållet i verksamheten?
This work is about popular culture in leisure. Teachers at leisure, on the basis of Education's governing documents working with developing an activity for students when applying the students' own interests. Although these councils are posted, several teachers around the country rejects certain activities or products that the students want to do or play with during their free time at the leisure time. Therefore the purpose of this study is to try to understand what teachers in leisure attitude to popular culture is and if they integrate the popular culture in there activities. To understand this, a qualitative study of interviewed teachers in various leisure was used.
Undervisningsmetoder för elever med autism : En studie av pedagogers metoder med avsikt att utveckla lärandet för elever med autistiska syndrom
This essay talks about how teachers in schools are working with a particular focus on students with autistic syndrome. The aim is to investigate the methods used for these students, who develop their learning and achieve the goals of the school. The methods that were used in this study were two interviews in two different schools in central Sweden where teachers and professionals were interviewed. One part of the study was to compare both schools to see which methods they used and when they used them. My interest for autistic students started during my practice in a school.
Ingen dag är den andra lik... på både gott och ont. En studie om hur det är att leva i ett förhållande tillsammans med en partner som har diagnosen ADHD
To live in a relationship demands hard work with good communications, mutual respect, compromises, empathy and an understanding of your partners feelings and needs. For a person with ADHD all of this can cause difficulties and create a strained relationship, but it can also mean a relationship with thrills, adventure, spontaneity and passion.
This study is built on a qualitative method using triangulation, where the studies empirical materials consist of 4 interviews along with observations online. The empirical material is applied on the theories: love, conflict and coping.
The purpose of this paper is to increase the understanding of how it is to live in a relationship with a partner who has been diagnosed with ADHD. The questions at issue are: How does everyday life work with a partner who has ADHD? What different aspects (positive and negative) are there to live in a relationship with a partner that has ADHD? How is the possible if any help and support perceived in their relationship and everyday life? The results showed that a relationship with a partner that has ADHD looks like any other relationship, but that it can differ due to the possible difficulties that are at hand.
