This has been a thesis work for an bachelor degree at Umeå university. The work has been done at LKAB?s facilities in Kiruna and its main purpose has been to investigate and construct some conceptual designs for replacing a screen with magnetic separation in KA3 concentrator plant. First all information available about magnetic separation was gathered and studies of magnetic separation at the sorting plant and studies of the plant KA3 was conducted. Companies that manufacture magnetic separators were contacted.

There is a new beverage container on the market, a bottle made out of pure aluminum as a replacement for the traditional container made out of glass. This new container has the potential to reduce both cost and pollution during transportation, the lighter and stronger construction has every advantage compared to the old one in glass. The new container has every possibility to make it on the market. Some of the biggest brands within the soft drink market already use these bottles in countries without any recycling demands like: Coca-Cola, Heineken and Pepsi. The only thing stopping these brands from the Swedish market is the lack of a functional return system, there is only one company that uses the bottle in Sweden today and they take care of their own used bottles.

The purpose of this study was to find out how caregivers experienced their psychosocial work environment at three municipal homes for old people. The Copenhagen Psychosocial Questionnaire (COPSOQ) was used in order to study different dimensions of the work environment, and questions about health, sickness presence and sick leave were included. The questionnaire was answered by 86 out of 112 participating caregivers (77%). The results showed that the caregivers experienced high demands at work. The degree of feedback and influence at work was low, but they reported that their work was highly meaningful and that they usually received social support at work.

The municipality, of Gatukontoret in Local government of Borås has in the long run, a required need to look after the current heating devices (the gas production plant) in sewage treatment plant, called Gässlösa. The practical work of the examination is about, trying to find a better way to take care of the current heat recovery. That may be one way or another, rather easy to implement in the existent construction.Through the work to increase the efficiency of the gas engine, implement of some external cooling system by heating exchange device. That gives an opportunity to heat (primary) the digester, (but even all internal public areas) with its own superfluous heating.The report shows that if the management group may invest 422 704 crown to implement a heat exchanging device, it gives more space to reduce the need to buy expensive external energy. Gatukontoret´s pay off time, for buying machines, is 20 years, with reservation to calculate with 4 percent internal interest, leads to the yearly mount of 31103 crowns.If Gässlösa increases the gas engine time in (effective) duty approximately (correspondingly) 48 hours a month the entire investment will generate a profit in January in year seven after the implementations.

Construction projects are generally designed as a general contract or a complete contract. In a general contract the commercial contract that is being used is AB 04 and related advice and instructions, AMA AF 07. In AB 04 there is an insurance requirement that stipulates that the contractor shall take all risks and liability insurance for the contract where the client must be co-insured.Construction law is almost exclusively regulated by the various standard contracts, one of those is AB 04. The Construction Contracts Committe is an organization that has published the standard contracts in this area of law and also the advice and instructions to help the parties to understand the agreements. The insurance requirement occurs in an area of law that is complex and the meaning of the concept is not entirely clear, nor which of the parties? interests and responsibilities that are covered by the types of insurances that are provided by the insurance requirement.

Today there is a widespread opinion that the woodmarket and the forest industry are dominated by a traditional way of thinking and not adapted to the customers of today; a lot of products are produced purely on routine. Also, there is a demand for improving the quality of sawn woodproducts. AB Karl Hedin wants to sort this out by increasingly adapt their products to the demands of the market, i.e. through introducing a short wallstud of standard length, "Hedinregeln". At tirst, the wallstud will be produced in lengths of 2,70 m and of guaranteed quality.

This report aims to describing the work behind the development of a masonry heater.The masonry heater is developed in collaboration with the company Transient Design KB that is a product development company located in Alingsås. The company sees a possibility to cover a market segment where modern technology and design are missing.The report presents those methods and approaches that have been used and gives an overview to how the project has been carried out. It describes how the ideas behind the final results have produced and how they have been developed during the project's time. In the report you can also read about the final concept with its choices of construction and materials.The report is completed with a presentation of a final concept and a ground for possible future production..

This final thesis is carried out at BAE Systems Hägglunds in Örnsköldsvik. The mission was to construct and integrate a new semi-active damping unit in the terrain vehicle BvS10. Questions that came up during the process, among others, was how to mount the damping unit to the vehicle in a flexible way without exposing it to unnecessary wears.A generation of the concept is made in 3D using CATIA V5 of a possible solution to the problem. The idea is to weld the unit to the skid girder which is one of the main constructions of the track system. In this way the damping unit will come closer to the track system, which will partly protect it from impacts from below and minimize current problems with breaking forces in the torsion shafts.The complete construction was then analyzed, first by theoretical calculations and then with the FEM-tools in CATIA V5.

 This report will describe a project between two students from Karlstad University and Markus Norström from Hovercraft solutions. The project aim was to develop a cabin for the hovercraft 380TD. The project was divided into two sub parts; one concerning the design of the cabin and one concerning the engineering. Throughout this rapport you can follow the engineering part of the project. The project has followed a systematic product development process resulting in optimized results for material selection and engineering solutions.

Storm water causes a number of problems in our country, particularly in city environment with its surfaces of non-absorbing ground materials. At heavy rain falls there are floods due to lack of capacity in the drain system when meeting heavy water masses over a short time. When the drain system is overloaded huge water masses reach the recipient untreated and there causing disturbances in the aquatic ecosystem. Due to emissions from mainly traffic, industries and other human activities the storm water is polluted. Earlier the problem used to be solved technically, by increasing the capacity of the tubes and by construction of reservoirs to delay the floods peaks.

The study aims to increase understanding and knowledge of motivation; this by examining how the leader experiences her capability to promote employees' work motivation. Also, how employees perceive that the leader influence and enhance their work motivation. Interviews were conducted with a manager and two employees of a government agency in Sweden. The results demonstrate different opinions between manager and employees in the manager's ability to foster motivation in the everyday work. The leader thinks that she promotes her employees work positively and believes that she is giving her employees attention and appreciation.

This report also contains a part about how a change in the work environment affects general people. The work started with studies of literature and design of the general part of the report and then continued with a practical study of house J. From the experience of the first two parts of the report a general help for planning a demolition was shaped.

A publicly funded elderly care that is widely available at people?s homes has been described as unique for the Nordic countries. There is much research that focuses on the relationship between caregivers and care receivers, and also about how work is organized in these organizations. However, research into how care work is organized in organizations that have implemented a salutogenic approach is limited. This is a qualitative study aimed to examine how caregivers feel that the organization of work in elderly care change after implementation of salutogenic elements in their daily work.
