Redesign av gallervält för Svea Redskap AB : Examensarbete, produktutveckling
The environmental debate is more intensive than ever before and the demands on companies increase. There are a number of methods to make it easier for the companies to fulfil the demands. Life Cycle Assessment (LCA) end ecodesign are some of the methods that can be used. Syntronic AB has the possibility to reduce the products´ environmental impact in the design phase. Therefore it is important for the company to make it possible to visualize the negative environmental impacts a product can cause in an easy way. It is also important to visualize for there clients if any improvement is possible. The purpose of this thesis is to develop a simplified model.
Grundvattenpåverkan kring järnvägstunnlar i berg
Rock groundwater has always caused major problems when tunnelling. Water leaking into tunnels can cause large problems, not only on the construction itself but also on the environment. A continuous water leakage can lead to a declining water supply, and geotechnical problems can occur as subsidence in the ground. Therefore it is of great importance to predict the consequences that can appear in the surroundings due to a declining groundwater surface.The aim of the study was to investigate different methods for predicting leakage and changes in groundwater level due to tunnelling excavations in rock. This thesis was performed by comparing mathematical methods, actual groundwater changes and results from preliminary investigations.Investigations were made for three railway tunnels planned by Botniabanan AB.
Användande av diffusionsspärr vid tilläggsisolering av äldre byggnader med trästomme
In the current situation a big part ofthe settlements that exist in Sweden isin need of renovation and energyefficiency in order to survive.Therefore, also many of the older houseswith a wooden structure are in a need ofenergy efficiency, which can be done ina variety of ways, including addinginsulation.This project deals with whether the useof a diffusion barrier or a vaporbarrier affects a wall structure byadding insulation to an older house witha timber frame. The insulation materialswhich are concidered in thisinvestigation are mineral wool and woodfiber insulation. Efforts are focused onthe effects of moisture on theseinsulation materials.To demonstrate the differences thatarise the moisture measurement programWUFI have been used to simulate avariety of wall designs. These designsare developed in consultation with theconstruction carers who are active inthe industry.Using WUFI graphs illustrating themoisture levels of the wall structureswere obtained and from these conclusionsvould be drawn. The work demonstratesthe differences that arise when using adiffusion barrier or vapor barrier inwall construction.
Vem köper KlimatEl och varför? : Kvantitativ undersökning av Kalmar Energis elhandelskunder
Private individuals can voluntarily buy EU Allowances (EUA) in order to remove them from the European Union Greenhouse Gas Emission Trading System (EU ETS). It leads to progressive reduction of total carbon dioxide emissions in Europe. Kalmar Energi offers customers to obtain one EUA (equivalent to one ton of CO2) per year by paying 25 SEK a month as a KlimatEl-supplement. The purpose of this research is to examine the customers? attitudes in the issue of climate compensation and trying to define the reasons behind their choices.The results of the quantitative questionnaire were analyzed by using descriptive and analytical statistical methods and have shown some correlation between customers? ages and decisions to accept or not the offer of KlimatEl.
Bestämning av jordmodul för kringfyllnadsmaterial runt rörbroar
Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.
Marte meo - "Show me" sade Maria: En kvalitativ studie av Marte meo terapeutens upplevelser och yrkeserfarenheter av metoden inom socialt behandlingsarbete
This thesis puts focus on Maria Aarts method "Marte meo" (on one's own strength). With the video camera as a principal tool, the purpose of the method is to be a practical working tool to support developmental processes on specific target groups, for example parents and their children. The aim of the thesis was to describe Swedish Marte meo Therapists and Marte meo Supervisors personal- and working experiences of the method, which was introduced in Sweden year 1991. Central questions were: How does Marte meo Therapists describe the essence of the method, it's establishment, development, and future in Swedish social services and psychotherapeutic treatment work? Which are Marte meo Therapists opinions of the methods relation to general problems and issues within social services and psychotherapeutic treatment work, such as the anchorage of theory and practice and the general claim for more research in social services interventions? In order to achieve the aim of the thesis a qualitative study was performed containing semi structured interviews with three Marte meo Therapists (two of them also titled Marte meo Supervisors).
Det svåraste som finns är att tänka i nya banor : - En studie kring personalhantering oh effektivisering av arbetet på svenska musikfestivaler.
Bachelor Thesis Music & Event Management School of Economics at Linneaus University of Kalmar, Economics, 2FE40E, Spring 2013 Author: Johan Hagelberg, Sofia Prins & Oskar Sjögren Supervisor: Petter Boye Examinator: Thomas Karlsson Titel: Det svåraste som finns är att tänka i nya banor - En studie kring personalhantering och effektivisering av arbetet på svenska musikfestivaler.Purpose: The purpose of this study is to investigate how different music festivals in Sweden can work to increase the efficiency by managing the workforce and internal knowledge.Method: The study was based on a qualitativ method with an abductive approach. The majority of the data comes from qualitativ interviews with persons in the industry.Conclusion: The music festivals in Sweden are acting under a constant economic pressure which leads to an experienced need for a larger workforce - mosty non-profit. The result of this study shows that the larger workforces are both unmotivated and decreases the effeciency of the work. The study aims to highlight the diffrenses between non-profit and commersial festivals and the way they work with human resource management and personal in different levels of the organization..
Value creation form a gender perspective - a case study of Caran
Women ledaers and profitability, is there a correlation? Earlier research show different outcome on the correlation between women leaders and profitability. A Swedish consultant firm, Caran has a belief that more women leaders would create more financial profit, we ask us if that is the true situation. Using two different IC measurement methods we have shown the difficulties in calculate intagible resources, which methods that can/ can not be used and if women leders create financial value. We found the women leaders in Caran to add more value per dollar spent on the woman leaders than the value added per dollar spent on men leaders.

Lika deltagande eller kompensation : En intervjustudie av hur högstadielärare förhåller sig till elever med dyslexi i undervisning och betygssättning
This essay aims to examine how Swedish compulsory school teachers claims to handle dyslexia while educating and grading, and to what extent they are influenced by others while grading. This was examined through interviews with a phenomenographic approach and the participants were eight grade 9 teachers. The categories of description found in the analysis was then interpreted through researcher Claes Nilhoms dilemma perspective, focusing on the dilemma Equal Participation - Compensation. Regarding education, three main strategies occurred: actions directed towards all students, methods of compensation organized by the school and individualized methods of compensation. The former is closest to Equal Participation, the latter to Compensation and the school organized methods form a middle position somewhat closer to Compensation.

Therefore we acquired the assignment to investigate the administrative part of the order fulfillment process in the company with the purpose to identify potential for improvement. This investigation was performed with focus on the terminal and packing functions. The purpose with the investigation was also to identify critical factors for an efficient order fulfillment process and investigate if information quality is such a factor.Data was collected through interviews and observations on Sandvik Wire. With the help of this data the information and material flows was mapped, the work within terminal and packing, and adjacent functions was investigated.
Sample cradle prevents pre-analytic error on platelet counts but is not essential for hemoglobin measurement and prothrombin time
Introduction: It is recommended to place all the vacuum tubes directly on a sample cradle after vein puncture to prevent analytic error. This recommendation is not always easy to follow because the samples are taken by different professionals under different situations. The three most common analyses, platelets count, haemoglobin and prothrombin time were tested. Therefore, it was interesting to compare results from the three most common analyses with or without sample cradle, to evaluate the influence of this step on the result. Methods: Three analyses were preformed, using blood from 50 different persons. Each person gave two vacuum tubes, each contained 4.5mL of venous blood for the study.
Miljömål 17: Hållbar konsumtion : Ett försök att integrera den svenska konsumtionens globala miljöpåverkan med miljömålssystemet
Environmental objective 17: Sustainable consumption - An attempt to integrate the global impact of the Swedish consumption with the environmental objectives system The aim of this report was to integrate the global impact of the Swedish consumption withthe environmental objectives system through presenting a suggestion for a seventeenth environmental objective ? Sustainable consumption. How the Swedish consumption pressures the global environment and methods to measure the affects was investigated. The pressure was divided into five main fields: climate, air, water, land and chemicals. The impacton humans and the biodiversity was also discussed, as well as differences between how men and women affect the environment and get affected when the environment changes.
