An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.

The aim of this master thesis is to examine information seeking andinformation use among high school pupils in two Norwegian highschools. The main research question focuses on different kinds ofinteraction or lack of interaction in the pupils? information seeking andinformation use.The theoretical framework of the thesis is based on a socioculturalperspective which allows for a specific focus of various forms ofinteraction. I investigate interaction in relation to concepts such associal practices, previous experiences and meaning making. Theempirical material consists of data from a large scale questionnaire (n=217) and in-depth interviews with six pupils.The results show that these pupils are used to interact with digital tools.The pupils trust printed sources more than digital ones, but at the sametime they prefer digital sources since these are easier to handle, it isquicker to locate information and this is easier to understand.

Title:Comparison of databases ? Is the law an obstacle?Authors:Alexander Ankarberg, Applied Information Science.Tutors:Lars- Eric LjungProblem: Cross running databases is getting more and more significant during the development of the information flow. There are huge benefits if we start to use the technique that already exists. The law is today an obstacle, so what would happen if the law wasn?t so stern.

This study investigates the corporate sustainability activity, linked to the company's core business, which is a relatively unexplored field in a Swedish context. The study examines how the organization has used management control for its sustainability activity within two social initiatives; and whether these initiatives have generated value for the organization and involved stakeholders. Management control of social initiatives are examined within the theoretical framework of The Sustainable Balanced Scorecard and the organization's value creation contributions are outlined in accordance with a definition of the concept of Creating Shared Value. The method used for the implementation of the study is a qualitative study, embodied in an illustrative case study of a large Swedish company operating within financial sector. The empirical data was collected through 12 in-depth interviews with representative interviewees within the organization and with other stakeholders involved in the company's social initiatives.

The basic ingredient of paper is the individual wood fibers. The property of the fibers depends on a variety of factors e.g., method of pulp production and processing. The final sheet quality depends in part on how the fibers interface between each other and therefore factors that affect the fiber size are of interest.The flexibility of the fibers depends in part on the pore water i.e., the fiber swelling. The sheet becomes less flexible at low water content which gives a loss in strength. Thus it becomes desirable to increase the water uptake.The experimental investigation described in this report consists of exposing the wood fibers to different ions and ionic strength and then measure the pore size by thermoporosimetry where a DSC (Differential Scanning Calorimeter) is used.

This study investigates the individual usage of the Dublin Core metadata format in three Swedish Subject Based Information Gateways, SAFARI, Svenska miljönätet and Svesök. The authors also present the reader with an overview of the metadata concept and explains in particular the Dublin Core Element Set. The approach to the study is investigation of Dublin Core application from the viewpoint of three major issues, user friendliness, interoperability and quality control. The study includes an in-depth comparison of the three different metadata templates, as well as interviews with people in charge of the metadata production at the respective SBIGs and users of the respective SBIGs« templates. The study shows that the three SBIGs are more similar than they are different.

Cultivation of grapevine is novel under Scandinavian conditions. We studied the impact of ground cover on frost hardiness of grapevine cultivars in Northwestern Scania in a two-factorial trial with four cultivars Solaris, Pinot Gris, Siegerrebe, Ortega and three kinds of ground cover (open soil, plastic cover and gravel). The study was conducted in a grapevine orchard, planted in May 2009, in Broddarp on Bjärepenisula Sweden (N latitude 56°; longitude E 12°). Soil and air temperature were monitored continuously. Frost hardiness measurements were performed every second week from late September to early December 2009. Frost resistance, LT50, was determined by electrolyte leakage measurement of the upper stems after artificial freezing at -15 °C.

Title: Artists? identity and image ? a brand perspective The purpose of this study has been to create an understanding of how artists in the music business can be seen as brands and to see what stands out when having this approach. During the study we have focused on the two terms identity and image. We find this issue interesting and relevant since branding has been widely discussed in business economy, but not enough when it comes to artists in the music business. To answer our research question we have targeted three aims for this essay, which is to clarify and analyze:? Identity and image when people are viewed as brands? What specifically characterizes the image of the artists when they are seen as brands and what it might mean that artists are considered as brands? How artists identity and image can be highlighted, shaped, influenced and how it can changeIn this study we have used a qualitative approach to get the topic in depth and gain a greater understanding for the subject.

Agile as an idea was created in 2001 through the Agile Manifesto with focus on social relationships, communication and flexibility. This was a reaction to the traditional, hierarchical organization with the goal of restoring balance within organizations in the IT business. Today we can see a transit of Agile from the IT-industry to other industries and areas, such as HRM.There is a challenge in attempting to traditionally control a social idea such as Agile, and there is a lack of empirical studies of the organizational context and its effect on the interpretation of Agile in practice. This study is an attempt to connect Agile to the science of business administration.The purpose with this study is therefore to research the organizational contexts effects on the interpretation of Agile in practice, within IT and HRM. Where Agile is established or well known.To fulfill our purpose we chose social constructivism as our scientifically approach, and conducted 12 in-depth interviews.

Stroke is caused by a bleeding or infarct in the brain and is one of the most common diseases in Sweden today. The purpose of the study was to evaluate if Ronnie Gardiner?s Rhythm Therapy (RGR-therapy) has any effect, regarding motor control and the subjective experienced health related quality of life, on people who have been affected by stroke. The examination group consisted of eight people. The intervention consisted of RGR-therapy once a week during a period of nine weeks.

The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.

Talking about sexuality -Medical staffs´ experiences of conversations about sexuality with patients at a cardiology unit The background of this essay is the taboo to talk about sexuality among people who suffer from some kind of illness. When a person gets ill and need medical attention, his or her life changes dramatically. The patients get treatment for their symptoms. The illness and treatment have often an influence on the patient?s sexuality.

The purpose of this thesis is to identify power structures and instruments of power within the Jehovah?s witnesses and investigate how they affect the baptized youths baptized within the organization. The material consists of qualitative in-depth interviews and is analyzed with Foucault's theories of power. The results show that the participants have a very strict relationship to the rules of the congregation and also that they take great care in observing these rules carefully. It becomes evident that young members are exposed to disciplinary measures from the organization.

What is it that drives a person with criminal behavior to change their lifestyle? What are the obstacles to a lifestyle change? These issues have been guiding us during this study. In the introduction, we describe the previous research that has been done among crime in men. The themes that will follow us through the course of the study are as follows; cause of crime, Self-efficacy, social network and lifestyle change. The aim of the study was to investigate the factors that a former prison convicted individual believes has been significant, as they break their criminal behavior associated with a lifestyle change.

Since energy simulations are used to verify that projected residential buildings will reach the current energy requirements it is important that the results are reliable.This report investigates the extent of uncertainty in energy simulations, estimates the causes of the uncertainty and its economic and environmental consequences.The method used in this report is based on three validation methods; empirical validation, analytical validation and comparative validation. The analysis was carried out for five multi-family dwellings in Uppsala with installed meters for energy measurements. One of these objects, Klockarlunden, was studied in more detail than the others.The results show that the deviations are between 10 and 29% for the studied objects, which means that the uncertainty is estimated to be at least 29%. All simulations underestimate the buildings need of energy. The simulation for Klockarlunden can predict the energy consumption to be within the range of 46-98 kWh/m2year with 90% confidence level based on the current uncertainty.
