Dooria Sweden AB is one of the main door- and doorframe manufacturers inSweden. They deliver door frames for indoor use for project oriented buildingsites, for these types of building sites the doorpost comes pre-assembled. DooriaAB wants to minimize transport to reduce impact on environment and thetransportation costs of pre-assembled doorframes, this thru simplifying themethod of assembly.The main purpose of this thesis has been to develop a prototype solution thatbrings the three parts of the doorframe together with the same properties regardingstability and tightness of joints as the current method of assembly. A profile ofdemands and wishes were created in collaboration with Mårten Dragstedt, DeputyDirector of Dooria Sverige ABBy following the chosen method the authors have been able to produce a fullyfunctional prototype that meet the demands that were put on the product. Catia V5R20 has been used as an aid during prototype construction and virtual tests.

The district nurses' duties with all organisational changes, above all during the last 20 years, have been changed. Economy and listing governs which visits that to be prioritized. The aim with this study was to examine what district nurses in the primary care in Uppsala län has for view about their occupational role. The method was qualitative and the selection comprized ten district nurses in Uppsala län that were interviewed individually on the basis of a semi structured interview guide that the authors the actual created. In the wide analysis of the results could a theme, As a rubber Screw in a shrinking hole and three central categories be discerned, Occupational role, Diversity and Organisation.

In Uppsala CHP Plant, there are six pressure reducing valves to reduce the pressure from 15 to 3 bars, before six absorption heat pumps. During the process the energy is conserved but losses occur in form of exergy. The aim of this thesis is to reduce the losses of exergy. This can be done by letting turbines replace the pressure reducing valves.In this thesis an investigation has been done of the conditions today, the conditions after the change from pressure reducing valves to turbines and a comparison of three different types of turbine solutions. The three examined solutions are one turbine, several helical Screw expanders and several small turbines in parallel with asynchronous generators.The six absorption heat pumps have been divided into two groups; one group of four and one group of two absorption heat pumps.

Denna uppsats undersöker hur blås- och stråkinstrument kan kombineras i en kammarensemble för att tillsammans uppnå en homogen klang. Åtta böcker i orkestrering har studerats med huvudsaklig inriktning på anvisningar som är relevanta för kammarensemble med enkelbesatt stråkgrupp. Vidare har tre verk för kammarensemble studerats: Louis Spohrs Nonett, Arnold Schönbergs Kammarsymfoni nr 1 och orkestermellanspel ur Benjamin Brittens opera The Turn of the Screw. Utdrag ur de tre verken analyseras utifrån samklangs- och balansaspekter och jämförs med innehållet i orkestreringsböckerna. Ett lyssningstest har genomförts där en testgrupp har fått lyssna på skalor som spelas av olika instrumentkombinationer.

The automotive industry is increasingly studying lightweight solution in their designs, also rational production and low costs in materials and manufacturing methods are of great interest. This thesis consisted in the practical evaluation of anchors for sandwich panels. The object was to study loads of shearing and pull out of the plane. The experiments were carried out on panels made up of 1mm aluminium coatings and 50mm extruded polystyrene (XPS) at its core. As the fasteners used simple methods such as blind rivets, Screw and glue.

At the Skoghall pappermill, sulphatepaper pulp is produced in a continuous digester originally from 1969. To be able to maintain a high level of production there is a need for a process with few disturbances. Variations in how well the wooden chips are packed in the digester is one form of disturbance. Today there are no available measurements on how well the chips are packed. Instead this is regarded as being constant.

In this work an assessment of the compressed air system in the facilities of Vattenfall Heat Uppsala has been conducted. The facilities constitutes, among others, a combined heat and power plant, and two waste incineration plants. The compressed air is supplied primarily by seven rotary Screw compressors and yearly electric energy consumption in these has been determined. Furthermore, the usage of compressed air has been mapped in order to find processes with energy savings potential. Several suggestions how to reduce the usage of compressed air have been presented, resulting in decreased need of electric energy and reduced CO2-emissions.The results show that total need of electric energy in the compressors, during a standard production year, amounts to 5.83 GWh.

The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a Screw press.

Purpose of the thesis is to construct a tool for car wheel change. Car wheels can be heavy and hard to handle and therefore the company Movomech intends to develop a tool that makes wheel change easier. Movomech does not have any similar product and because of this the work was condition less.The intended users of the product is tire workshops and there for the work began with investigation of these. The reason of the investigation was to see how wheel change is done and how tire workshops are planed. The tire workshops? crew?s opinions were also considered and above all one important conclusion was made.

Wavecraft AB develops medical equipment for heating of organic synthesises. The heating is done with microwaves, which improves the process in both speed and accuracy compared to the more traditional methods where heating elements are used. This report discusses the developement of an automatic lid mechanism for one of Wavecraft's product prototypes. The company assumes that the final product will be integrated by customers into fully automated systems, and the upgrade from a manually to an automatically controlled lid is therefore an important step in the product's developement process.The first stage och the project was an idea generation process. The ideas generated here were organized into five different concepts of which the best one was selected through the use of a concept matrix.

The company has clients from Lund to Kiruna, and from Norway. This means that the elements have high standards when they have to take many different loads from wind and snow due to such wide geographic variation.The roof elements are structured so that the main body is made of light beams with an I?profile.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.
