The aim of this report was to do a case study at a geothermal heating system which has been in operation for about 5 years, and study if its performance has changed during this period of time. A literature study about the processes involved was also done in purpose of background knowledge.The tenant-owner?s association Duvan at Petterslundsgatan in Uppsala installed year 1999-2000 a geothermal heating system. The purpose of this installation was that they hoped it would lead to a smaller usage of district heating which would lead to a reduction of the heating expenses for their buildings. The geothermal heating system consists of 19 energy wells and 4 geothermal heat pumps, and it is one of the first systems of that size in the region of Uppsala.

Background: Since the early 60?s, the CAPM or Capital Asset Pricing Model, has been an invaluable tool for assessing an asset's expected return, assuming that the asset is added to an already well-diversified portfolio of assets. CAPM theory assume that the unsystematic risk can be diversified and that the systematic, market-specific, risk is determined by the Beta value, from the Greek ?. An investor who takes big risks expect higher returns.One of the CAPM?s basic assumptions is that disruption in the market is not taken into account.

For many decades the increase in traffic volume, expansion of highways and infrastructure has lead to an increase of wildlife vehicle collisions which are unfortunately very common in many countries today. They cause great deal of material damage and even kill humans or wildlife. Measures in the form of warning signs, under- and overpasses and fencing have been implemented for a long time with the help of observation by hunters and collisions sites. However this study focuses on the moose?s perspective and the variables that, both spatially and temporally, could have an effect on why and when moose are close to certain types of roads.

Abstract (in English)The work that lead to a CE- marking and the creation of a total drawing foundation on an existing machine carried out on the company Polytec Composites Sweden AB in Ljungby.

The process that summed up all the document that needs for the machine to make a CE-marking. The documentation includes a total drawing over the machine and a risk analysis performed by a group employers on the company.

This essay takes a closer look at femininity/masculinity, sexuality and queer time and place in Charlaine Harris? novel Dead Until Dark (2001). The essay?s theoretical framework consists of queer theory and skev theory. Skev is a Swedish word that translates loosely into strange or twisted.

This report describes the development of a sample loader for my diploma work at Q-linea AB in Uppsala. The sample loader will replace the process of loading fluid samples into Q-linea?s instrument for biomolecule analysis. The earlier process was done by hand and was a time consuming and inefficient task.The work was initiated with a design phase where an overview of the system was created. The sample loader will be receiving text commands from a PC that coordinates all the subsystems like pumps and lasers on the analysis instrument.

The aim of this report is to investigate how the work handling at the department for arriving goods at EFG in Tranås is working, as well as how it could be improved and made more effective. EFG is a corporation who process and sell office furniture. The company is working with a project concerning delivery precision, the subject is therefore particularly interesting from the perspective of delivery accuracy. The number of orders has increased notably during the fall of 2005 and the spring of 2006. This has led to new demands at the department for arriving goods and the topic is as a result of that important also from this point of view.Interviews and investigations have been conducted at location since no written material earlier has been made in the topic.

Within system development users have rarely been involved or received much attention during the development. Most of the times, the primary focus within system development lies on insuring functionality, rather than making the system usable. The literature specifies that a non user-centered approach can contribute to a product with low usability, which can lead to an ineffective and unsatisfactory experience for the end users.The purpose of this thesis is to begin an investigation to see if the use of non user-oriented system development methods is a possible cause of low usability in the final system.To achieve the purpose of this thesis, we have conducted a case study. Within the case study we examined the usability of a time reporting system. The case study included seven minor studies; an investigation concerning the development of the system, an expert evaluation of the system, interviews and observations of users, developed paper prototypes and executable prototypes, both which user testing was performed on.The result of this study shows that by working with user-entered methods, the usability in the time reporting system increased after the design had been revised.

In central Jönköping, on Munksjöns northern waterside a shopping centre will be built, on the block Atollen. The construction will begin in autumn of 2007 and will be finished according to plan in 2009. Atollens goal is to counteract the competition from external retailers and strengthen the retail trade in the city centre, leading to more attractive and competitive city centre.Atollen will not be a shopping centre in traditional style and design, it will be focused on shopping and experience. The shopping centre shall be a natural venue with a wide and exclusive store mix, concentrated against trend conscious customers. This will be created with the help of a futuristic design and architecture, with light, open and transparent spaces.

Stockholms vattenskärning AB in Kungsängen has through the acquisition of a company begun to design and produce aircraft heaters whose origin is early 1970s which follows a high inefficiency in terms of energy consumption and size.The aircraft heater, which is sold worldwide, serves its purpose for customer satisfaction and has done so ever since it was developed in the 70s.Stockholms vattenskärning AB is now investigating the possibility in making the aircraft heaters more efficient, both in terms of energy consumption but also on a more efficient design with the belief that it would lead them to an edge in the market. The aircraft heater consists of several main components whose function altogether is to keep passenger aircrafts warm while they are on the ground.This project has been limited to the further development of the heat exchanger package which accounts for the conversion of the hot medium to the fresh air being carried in to the aircraft cabin. Work has been divided into different phases in order to create a better understanding of the project range and to make it easier to divide the various elements in the time available, 10 weeks. These phases are literature review, situation analysis, concept generation, CAD, concept comparison and writing reports.After the initial literature review was made, a fundamental theory was written which is essential in understanding the remaining parts of the project.With the theoretical part as support, measurements and calculations were made on the current heat exchange package in a situation analysis to ensure its operation and efficiency.In the concept generation phase, the collected facts from the literature review was used as the basis for creating a matrix. The purpose of the matrix was to indicate the two most suitable types of heat exchangers to develop four new concepts out of.In the CAD phase the four concepts was drawn up and then described with text and images.The last phase is the concept comparison where a concept selection matrix is used to function as a decision basis for further production at Stockholms vattenskärning AB. The four concepts have been developed based on the current heat exchanger and is gradually changed into a design of a cross-flow heat exchanger constructed out of stainless sections. The purpose of this is to have gradual upgrading of the heat exchanger as an option, in order not to saturate the market..

AbstractThis thesis examines and discusses a sample of the medieval hypocausts (stone-heating ovens) in the Baltic area. The medieval construction is thoroughly explained as well as the antique hypocaust in order to establish a base for the following discussion. The medieval hypocaust has been almost forgotten for a long period of time. The last time someone dealt with this category of finds were in the 1960?s by Swedish archaeologist Iwar Andersson and in the 1970?s by Danish archaeologist Johannes Hertz.

High quality within a Lean production system begins with standardised work, which creates stable processes able to generate predictable output. If nonconformity from the standard procedures occurs, routines are needed to analyse, correct and prevent the nonconformity from occurring again. In that way, the nonconformity can be a trigger for continuous improvements toward more stable processes. In takted production lines, where the operator follows a standard sequence with tasks set to be completed within the takt time, a nonconformity leads to downtime in the operator?s sequence, and no value is added.

At SLU, Divison of Reproduction, Dept of Clinical Science, there is an ongoing project on the development and evaluation of new methods for the assessment of stallion semen quality. This EEF-study, which is a part of that larger project, has focused on the effects on motility and fertility of stallion semen of two different extenders and selection. Both an objective method and a subjective method for analysis have been used and compared in the study. The increase in the use of artificial insemination with cooled semen in Swedish horse breeding over the last decade is thought to play a part in declining foaling rates (Kareskoski et al, 2006, Kuisma et al, 2006). This calls for better evaluation methods of semen quality since cooling and transportation put higher demands on semen quality in order to maintain fertility (Aurich, 2005).

Early contact with both parents is important for children and it is important to reach out to both mothers and fathers through parental education groups. Parent education program for fathers can lead to more fathers taking parental leave and becoming more involved in the care of their children. A lot of men lack support from the community after the birth of their child. The aim of this study was to illustrate district nurses? experiences of meeting first-time fathers.

Introduction: Increased ill health in the workplace in terms of increased workload, stress and pressure from employers is common in Sweden today, which may lead to a future variety of medical conditions and disabilities. Aim: The aim of the present study was to describe what employees at companies in the health industry experienced as a health and illhealth on a workplace. Method: A qualitative approach was used in which the interviews were based on an interview guide. The method of analysis was thematic analysis in which three themes emerged. Results: Tree themes emerged; a social interaction with colleagues, good leadership, and access to health care and movement.
