AbstractIn urban societies people spend more and more time indoors, which put great demands on the indoor environment. If the ventilation is to manage the removal of unwanted substances in the indoor air, a good mixing of the air is required. The question arises that, whether the buoyancy forces will counteract a good mixing of the indoor air or not?This report aims to clear up the difficulties whether you need to consider the buoyancy forces or not, when adjusting a ventilation unit. For studying the indoor mixing of the air a two dimensional model is constructed in COMSOL Multiphysics.

A manufacturing machine at the engineering company Sandvik Coromant has a positioning table which task is to move an item linearly. The positioning table has a linear motor capable of high velocity and acceleration. This makes it possible to achieve short cycle times and a more profitable production.The purpose of this thesis is to bring forward a new concept which is more adapted to the requirements of the positioning table. The reason is that the current positioning table provides an unnecessarily positioning accuracy of 0.01 mm, while the requirement for the positioning accuracy is just 0.1 mm. The goal is to reduce manufacturing and component costs.To develop a suitable solution an approach for the concept development process has been performed.

AimThe aim has been to describe the goals and the pedagogic model concerning physical education in the Waldorfschool. Further purpose was to describe what the teachers focus on in there teaching roll about physical education. We have also chosen to give a picture of what other documents says about the teaching roll in booth the Waldorfschool and in the traditional municipal pedagogics. The Waldorfschool runs under Lpo 94 but they can also as other schools adapt and formulate there own curriculum after there pedagogic. That?s also why we have chosen to look at what the teachers says, about how they work and trying to achieve the goals of the curriculum in physical education.Framing of the questions? What does the teachers think affect and develop the teachingroll in the Waldorfschool?? How does literature describing the teachingroll/physical education roll in the Waldorfschool?? What does the teacher in physical education says achieve to, counter what the curriculum says about physical education in the Waldorfschool?? How does the teacher do to achieve the goals in the Lpo 94?MethodA literature research of relevant previous studies was made among others in the database Eric.Curriculum for the Waldorfschool and books about Waldorf pedagogics and the teaching roll has been studied.

Background: Goodwill has been a hot and debated topic for a longer period of time. Researchers have debated how goodwill should be accounted for and have not come to a solution. In 2005 IFRS standards came which meant that goodwill no longer will be amortized according to plan, but to be put through a yearly impairment test.Problem: A number of disclosure requirements in the financial reports have been made in an effort to avoid companies to account for goodwill differently. Apparently there still is a problem of how companies account for goodwill and there are several studies in the subject. But no one has studied how it is between two different industries, which make this study interesting to execute.Purpose/questions: This study have the purpose to investigate how the industries day to day wares and health care regards the disclosure requirements for goodwill by the impairment tests.

During the years 1950-75 was the construction of building apartments in high speed. A rapidly growing reconstruction requirement is the consequence of the rapid construction speed in these years. The technical lifetime of the different parts of the buildings is about to end and the needs for reconstruction is huge. One of Sweden's national environmental objectives is to reduce the urge of energy in buildings. This calls for radical measures to implement energy efficiency of existing assistance particularly in the assistance that is now facing reconstruction.

The Kverneland Ecomat and The Ecomat Seeder has been tested in three different field studies. All the studies were conducted on soils with different clay content during 2005 in Säby outside Uppsala. In one of the trial spring ploughing with the Ecomat and spring ploughing and seeding with Ecomat Seeder were compared with conventional autumn mouldboard ploughing and spring mouldboard ploughing to conventional depth (22-23 cm). In this study the quality of the seedbed, the number of emerged plants and weeds, the pentration resistance and the yield were examined. Shallow spring ploughing (10 cm) with the Kverneland Ecomat has shown to be a good alternative to conventional autumn ploughing when growing spring crops. During the season 2005 tilling with the Ecomat resulted in a higher yield than conventional ploughing. In 2002-2005 the average yield for shallow spring ploughing was 4 percent higher than after conventional autumn mouldboard ploughing and 10 percent higher than after spring mouldboard ploughing to conventional depth (22-23 cm). In the other two studies, ploughing to different depth in the autumn with the Ecomat was compared with conventional mouldboard ploughing and stubble discing.

Ett passivhus är byggt av stomentreprenör företaget Strängbetong i Vara med ventilation och uppvärmning i samma system som kallas för Termodeck. Uppvärmningen sker genom att tilluft från ett FTX-aggregat förs igenom håldäcksbjälklag som värmer upp bjälklaget. Med det erhålls ett ?värmegolv och värmetak?. För ett sådant system behövs en byggnad med tung betongstomme.Energibalans beräkning har gjorts med IDA program och schablon värden från olika kravspecifikationer som visar simulerade värden.

ABSTRACT The purpose of this medical record research was to study 30 patients with chronic subdural hematoma on a neurosurgical clinic, mapping documented nutritional status, preoperative fasting and hydration and energy supply before surgery. In addition peroperative administration of fluid and vasoactive drugs, as well as postoperative complications and length of hospital stay were studied. The mean age of the patients was 71 years. Nutritional status was evaluated in 12 patients, out of these seven were judged to be at risk for under nutrition. Fifteen patients had surgery day 1 (total fasting time on average m 11 h), eleven had surgery day 2(29 h), three had surgery day 3 (35 h).

The purpose of these theses is to show the financial economical situation during the change from conventional dairy production to ecological production. The thesis is accomplished by collecting information from literature and interviews where needed. The target group of these theses is dairy producers who will transform their production from conventional dairy production to certified ecological dairy production. The theses emphasise on the economic situation during the adjustment years. For this I have studied a presently producing dairy farm.

The starting point of this paper has to do with rapid changes within the information technology and the need for agile and fast systems. The primary goal is to investigate what happens with recordkeeping practices in agile environments like service oriented architecture (SOA). It is in the possible transfer between IT architecture and digital archive the area of this paper resides. The paper relates to the Records Continuum model by which records will be considered historical and active at the time of creation. In the Records Continuum model recordkeeping practices and archival requirements will have to be taken into account at the time of creation.This paper concerns SOA from the perspective of Archival and Information science.

In claims for unfair dismissal due to alleged redundancy, the burden of proof should be shared to enable an employee to have the cause of redundancy tried. In such a case, the employee should present evidence of an invalid cause ? such as personal reasons ? and the employer should account for the redundancy. With reference to their conflicting interests, the law favours the employer if the redundancy can be accounted for even if the employee maintains his or her position. This would have been reasonable practice if the employer?s evidence was subject to the same scrutiny as that of the employee but, as long as redundancy is considered a valid cause in itself, this is not the case.Redundancy does not come from nowhere, but it occurs when employers carry out their management decisions.

Public WiFi networks is one of the dominant technologies for users to get public internet access. The problem is that the networks are designed for accessability rather than security ? a problem users seldom are aware of. Users who carelessly access WiFi networks may reveal sensitive information which, among other things, can lead to an identity theft. Previous research suggests that users must be educated and informed about the risks they incur, but not how this should be done.

This thesis describes the development of a tank insert for diesel cars, from idea to a prototype. The idea is to design an insert which makes it impossible to refuel petrol in a diesel car. The insert shall be installed in the existing tank opening on diesel cars. The tank insert is designed for the Swedish company SverigeGrepen AB located in Vänge, just outside Uppsala. Their main product is a pitchfork that is ergonomically designed and durable.A pre-study were performed in which information relating to fuel caps, tank openings, petrol- and diesel nozzles were collected.

Saab Aerosystems have had one dominating product, JAS 39 Gripen, and one dominating customer, FMV, for a long time. The operations management system at Aerosystems is adjusted for development of Gripen and as the business unit is trying to enter new markets with other products and customer the operations needs to be adjusted to fit the development and manufacturing of these products as well.The purpose of the master thesis has been to investigate how Aerosystems is managing requirements on operations from external customers and how to make improvements within this area. The aim has been to carry out a situation analysis to identify where improvements are possible and then produce proposals for improvements through studies of literature and other business units. The thesis also include a study of knowledge transfer within the business unit to investigate how this can be applied to improve the managing of requirement on the operations.An extensive interview study has been carried out in which interviews mainly have been conducted with employees at Aerosystems, but also at Saab Avitronics and Saab Aerostructures. The reason why these business units have been examined is because they have carried out a large number of successful businesses with external customers, which also are potential customers for Aerosystems in the future.The interviews have been analysed to identify strengths, weaknesses, opportunities and threats with the present way of working.

Today there is a limited demand for quality certified cereal in Sweden. The demand can in the future increase and become a requirement for the entire market. Since the first of January 2005, grain producers in Sweden are food producers and traceability is important for the food industry. It is possible for grain producers to certify the productions under the certification IP SIGILL. The purpose of this essay is to explore why some grain producers continue to be certified while other producers end the IP SIGILL certification.
