Detta examensarbete gjorde jag för att försöka ta reda på vad ett riff kan vara, och vilken roll riffet har inom hårdrocksmusiken..

The core process is responsible for internal business development and is the process that runs through the organization and the results which creates a value for the customer. Some research suggests that identification of the client's conscious or unconscious needs clarifying the so-called core process in the organization and operations can thus be more effective. The study aims to identify and analyze the experience of the core process within child health care. The method has been interviews with nine managers and 10 clinic nurses in a county. The results show a lack of knowledge regarding core process and process work.

Ensåsengruvan is a mine situated within Ljusdals municipality in central Sweden. Themine was in use from 1984 to 1991 and has since been undergoing a remediation program. Mine tailings from sulfide rich ore is a potential environmental hazard due to its tendency to cause acid waters and heavy metal leakage. Lake Ensjön is situated one kilometer from the mine area. Due to the hydrological conditions it was not expected to receive inflowing water from the mining area.

High-precision cutting in metal is very complicated, a lot of parameters affect the result: what geometries to be manufactured, surface roughness and tolerances to be achieved, batch size etcetera. When pull-broaching internal parts this might be even more important, than in any other cutting operation. Everything is machined in one single stroke and the general technology is built in to the tool, therefore big investments must be made to change the process. Milling for an example: one piece at a time is machined away, and a lot of parameters can be changed easily.It is very high pressure on the cutting-edge when the broach is cutting. To achieve the specified product and to avoid unnecessary toolwear it is essential to use the right cuttingfluid and the right cuttingspeed for an example.

Chlorinated aliphatic hydrocarbons (CAH´s) were used widely within dry cleaning facilities and for metal degreasing until their toxicity was discovered. PCE is still used as dry cleaning liquid. Today CAH´s are found in soil environment at places where they have been used in the past. The CAH-concentration in trees growing on contaminated land has quite recently received attention as a cheap and effective way of assessing the extent of a CAH-contamination. The method has however, not been put into use in Sweden.The aim of the study has been to investigate whether the CAH-concentration in tree cores could be used to delineate the spread of CAH in a soil environment under Swedish conditions in different seasons.

Since 2007, I´ve been working in the steel industry in a place called ?SSAB?. That?s why itseemed right to contact them for this thesis.The SSAB concern is global, but SSAB Sweden involves raw steel producing in Luleå, heavyplate producing in Oxelösund, and sheet metal producing in Borlänge..

The aim of this study is to examine the investment decision process for investments that arise due to strategic changes and are of strategic importance to the company. At the foundation of this study is the previous research in this area, done by King (1975) and Bower (1970), which examines the investment process on a more generic level. At the core is the investment decision process pertaining to Projekt X, an investment performed by NordiCorp. Having conducted a case study including six interviews with employees from various parts of the organization, combined with a large number of internal documents, the process regarding the investment decision was carefully illuminated. The results show that in many regards, this process follows the more generic investment process.

To implement an ERP-system is not an easy process. The success of the implementation depend on many different variables. The most important one is perhaps the requirement process, to define what the organization wants and expects from the system. In this study, the advantages of a process mapping are examined, in relation to the phase where the requirements are expressed in an ERP-implementation. The conclusion is that a process mapping generates an increased communication with the supplier of the ERP-system, hence the business knows their processes and thereby what they want from the system.

AbstractThe research project Liberation, supported by the European Commission under the Environment and Sustainable Development Programme (Fifth RTD Framework Programme) aimed at developing a decision support system for ecological risk assessment of contaminated sites has proposed a tiered system including the triad method. This method integrates contaminant chemistry and bioavailability analyses with observed ecotoxicological effects in soil and groundwater. In this study the triad method was used to perform a risk characterization of a former surface treatment and metal industry, now used for the student union buildings of the Mälardalen University in Eskilstuna, Sweden. On the site, high concentrations of copper, zinc and nickel have been detected in the soil in a preliminary investigation of contaminant levels with XRF. For performing the risk assessment of the site according to the triad method, contaminant bioavailability, soil metal concentrations and soil toxicity were determined and an ecological assessment was carried out on four selected soil samples (one reference soil and three samples with low (B), medium (C) and high (D) contaminant levels). Contaminant bioavailability was measured through leaching (ISO TC 190/S7) and biouptake tests (DGT).

In cooperation with the Gislaved company Lerocon AB [1], a separation module wasdesigned as a further supplement to the Module System. The aim of theprojectimplementation was that the separation module could be flexible enough to feed themetal pieces, screws, nuts and other items with large variations of size, appearance andmaterial composition. The module should also be cost effective to manufacture.A separation module is a design which is ment to streamline the work in industries withautomation of the lineoperations. The module feeds the details such as screws, nuts, washersand pieces of metal in a continuous flow in which traps separate the details from each other.Traps may vary depending on the purpose and of the details that are fed. Perhaps it isimportant for the user that the detail-orientation is right after the separation module, whichmeans that all the pieces witch aren´t are fed back in return.For companies and industries in lineoperations that can be made more efficient withautomation, are production flow an important watchword.

Highly polluted urban storm water from e.g. highways can contain large amounts of heavy metals that may cause harm if they are discharged into recipients. To remove the heavy metals a possible low-cost method that does not require much maintenance, could be the use of reactive filters with filter materials consisting of industrial residues or other cheap mineral based materials. Dissolved metal ions are removed by reactive filters through the processes of ions binding to active sites on the surface of the filter materials, or by formation of insoluble precipitates.The ability of CaO-treated granulated blast-furnace slag, iron oxide coated sand, olivine and nepheline to remove seven heavy metals (Cr, Cd, Cu, Ni, Zn, Pb and Hg) from urban storm water was studied. Initially batch experiments were performed where the effect of pH, dissolved organic carbon (DOC) and dissolved ions on the adsorption efficiency was studied.

Welding is a common method for joining of metal or plastic construction parts. This report describes several different weld methods in general terms. The report focuses on the GMAW method, specifically MAG welding.A case study has also been performed for the company Wenmec. The task received from the company was to compare the mechanical properties of joints welded with the tube electrode called Nittetsu SM-3A and joints welded with the homogenous electrode called ESAB Aristorod 12.63. Both types of weld joint were welded with the MAG method with an Argon based shielding gas with 18% CO2.
