The basis of the study lies with a newly patented gearbox by cardiologist and inventor Stig Lundbäck. Stig founded CorPower Ocean AB to further develop the gearbox to be used in a wave energy device. The purpose of this project is to develop a concept of a lifting system with CorPower Oceans gearbox that is more energy efficient than a hydraulic lifting system. The goal is to use technology from CorPower Oceans gearbox inversely to perform heavy lifting as an alternative to hydraulics. The project is limited to applying the gearbox and gear rack on a forklift with a lifting capacity of ten tons.The main tool in this project will be the product development process Systems Engineering where only the most relevant parts will be used to develop a concept.

Open pit mining creates huge amounts of tailings and waste rock deposits. Due to it's content of sulphide minerals, predominantly pyrite (FeS2), there is a risk of oxidation and formation of acid water containing Heavy metals, known as Acid Rock Drainage (ARD). To prevent the process of oxidation, the tailings and waste rock have to be reclaimed. The most commonly used methods of reclamation are a coverage of water or soil. Mining also results in a large-scale interference in the landscape that will make an eternal change of its appearance.

The main purpose with the project has been to approximate the magnitude of the pollution transport from the actual road surfaces and to get an approximation of the possibility to collect the pollutants to reduce the load to the water and improve the water quality.The quantity of pollution transport from the most trafficated roads areas in Örebro city has been calculated. Roads whith a traffic exceeding 10 000 vehicle/day. The study has been done with the calculation tool StormTac. Through analysis of traffic loads and road surface, which together with a different kinds of parameters gives an approximation of the pollutant transport.The calculation has included some metals and other substances in the stormwater and has also included the present of suspended solids. Included the overall study, some smaller areas has also been calculated for the possibility to remove pollutants.The work also includes calculation for three different areas for stormwater treatment.

Since feeding fodder crops to dairy cows is a heavy and time-consuming but often disregarded line of work, this study wishes to view the different possibilities that are currently available to decrease the time to feed and apply this knowledge on an existing farm. For this purpose, four farms have been studied due to what feeding systems that are currently used and how long time the feeding required. The occurring systems are either mobile, i.e. a feed mixer operated by a tractor witch feeds the cattle via a drivable fodder table, or a stationery mixer, i.e. an electrically powered mixer which fills an automatic feeder.

This essay is about Late Iron Age settlement and its production. I want to define the nature ofthree different workplaces on Bornholm, Denmark, and compare them. My aim is to see if itis possible to define a workplace through the traces of the craftsmanship. Several materials areselected in this essay and the analysis provides different perspective on workplaces in the LateIron Age in Scandinavia. The results of the analysis between the three workplacesAgerbygård, Baggård and Kanonhøj shows that Baggård have more traces of melting of bronsthan any other of the places.

The aim of the study was, through qualitative interviews with school counsellors in Swedish primary schools, to study what the counsellors are experiencing condition their ability to work proactively according to the Swedish Education Act provisions on student health. During the study, six interviews with school counsellors who worked in the same suburbs, was conducted. The theoretical approach that was used is Michael Lipsky's theory of street-level bureaucrats and the term discretion. The overall outcome of the study was that the interviewed school counsellors felt that they did not have good opportunities to work preventively as the Education Act requires. The main reason for this was the school counsellor?s heavy workload.

Aim: The aim of this study is to understand why people have changed their preferred community over time. What are the main factors when changing to a new one?Method/material: The method has consisted of personal interviews with six different people in the ages between 20-22 and of different gender. The main material that has been used in this essay is the theory of Uses and Gratifications as explained by Denis McQuail, the theory of Convergence culture by Henry Jenkins and the theory about Communites of Practice by Etienne Wenger.Main results: This study shows a heavy affection that the use of communities often centers round the people around the community, rather than the functions that the communities themselves provides. Having people that you know on the community you choose is a vital part for people or at least having the support of other people and changing to another community at the same time.

In the following study I probe the social world of hard-rock music. By conducting interviews with four young male enthusiasts of this music I try to develop a general picture of this social world, as well as of the basic elements on which this particular subculture is constructed. The identity of a hard-rocker is based upon a number of factors beyond just a preference for that music. Throughout the interviews I encountered many implicit norms that one must followed in order to be able to see oneself as a true hard-rocker. I also found that from the respondents? perspective, the mainstream culture has, throughout the history of metal music, used various ways to counter the spreading of this genre.

This essay focuses on the press coverage of the riots in Gothenburg 2001. The questions it aims to answer are, How is it that although the media was gender-neutral in its news reports, the lasting memory is one of rioting men, and why did the media simultaneously exaggerate and minimize the importance of the riots?The material consists of articles and photographs from Swedish mainstream newspapers. The method is text analysis, with a heavy influence of discourse theory. The conclusions are that since the hegemonic discourse on gender does not allow women to be active and violent, all bodies in the riot automatically become men, no matter how female they seem to be in other contexts.

This is a thesis about the American empire. I also focus my work to see if this American empire is declining. The two main questions I ask and want to answer in this thesis are: is America an empire and is it in decline?I first conclude that America has been an empire ever since the end of the Second World War. The sheer military and economic power of the American empire matches and exceeds the ones before them.

Statistics of occupational injuries show that bricklayers are among the most exposed, with heavy lifting by far the most common cause of long-term sick leave. Prefabricated brick beams create yet another risk of injuries that can be prevented by auxiliary equipment or alternative solutions. From articles, interviews with masons and from a survey carried out in conjunction with this report, it appears that there are frequently difficulties in the use of available means for lifting and handling. Previous studies on the subject of transverse reinforcement in masonry beams indicate a viable method for bridging large openings in masonry walls. This bachelor thesis delves into whether the idea could be realized in today's brick construction with a view to improving occupational health and safety.

The object for this study is a company developing and manufacturing vehicles for heavy transportation. The company distributes their products on a global market. Therefore the company is required to have efficient internal production development processes in order to successfully beat the competition. The purpose of this master thesis is to study how this particular company intends to implement their standardized theoretical product development process within their organization and how well it is done. We intend to identify and specify if the process has any unexploited capacity.

Volvo Hauler & Loader Division in Arvika produces wheel loaders which they deliverthroughout the world. The factory which is situated in Arvika is the largest wheel loader plant in the whole world, with its 1 100 employees. The different models stretch from L60E all theway up to the brand new L350F, with a loader capacity from six tons up to a staggering 35.The assembly of the different models are divided into three different assembly lines, Small(L60-L90), Medium (L110-L120) and Large (L150-L220). The assembly of Heavy (L350)has just been started with an upcoming pre series.This examination paper gives recommendations of improvements and necessary modifications to rationalize the pre-assembly of boom units. Three different scenarios are presented in the paper.
