The purpose of this work was to provide a better understanding of urea?s decomposition and byproduct formation in an SCR system on heavy trucks. In my experimental setup with TGA-DSC-FTIR (a combination of two thermal analysis methods and a method for gas phase detection), an FTIR method for urea in the gas phase was developed for the qualitative and quantitative determination of urea and its decomposition products. Chemicals such as urea, biuret, cyanuric acid and melamine of p.a. quality were used in this method development. Beforehand, there was no FTIR method available to detect these substances; hence, the aim of this work was to develop an FTIR method to understand the degradation chain of urea. The combination of TGA and DSC was used for analysis of different samples, where urea, biuret, cyanuric acid and melamine in varying amounts have been weighted in for various experiments in order to study the temperature at which a phase transition or reaction occurs, i.e.

This masters thesis investigates the relation between China and the Information Society as it is manifested in the UN conference the World Summit on the Information Society WSIS. The first phase of this two-phase conference took place in Geneva 10-12 December 2003, with two documents, Declaration of principles DP and Plan of action PA, as main results. The information policy is central to an authoritarian rule in its efforts to keep control over the national identity. The thesis investigates the impact that the information revolution and Internet might have on the Chinese national identity through the acceptance of DP and PA in various aspects. With the use of the information science theories by Manuel Castells and Frank Webster, the vision of WSIS was compared with the Chinese information policy.

Compressed air is an energy source that is widely used in today's trucks and buses.Compressor located next to the engine supplies the pneumatic system with the compressed air and is lubricated with the engine oil. Some of the oil follows the air flow in both liquid and solid phase. The solid phase, namely the carbon particles are created due to the high temperature in the compression chamber.Oil- and particles carryover softens and destroys the rubber material in the air valves and disturbs the mechanical function of various components in the pneumatic system. In order to reduce oil- and particles carryover is an Air Processing System (APS) set downstream the compressor.No method for establishment of oil- and particles carryover from the compressor exists at the moment. Therefore the filtration efficiency of APS is currently unknown.

This diploma work project is a product development project which purpose is to redesign a braking system for a walking frame. The system that was developed diverges the force from the user to braking power, and includes a service brake as well as a parking brake. The most important components of the system are a grip handle on where the user holds on to and a braking handle on which the user operates the brake from. The system also includes a power transmission component, braking package and other mechanical components. All of the components wasn?t developed in this project, several off them has been reused from the existing system.This product has been developed to meet the requirements and standards presented from the principal, Ahlberg Leber.

Purpose: The purpose of this study is to examine how venture capitalists implement ESG issues internally, as well as before the investment decision and during the investment period.Theoretical framework: The theoretical framework consists of previous studies that identify different driving forces behind the work of the ESG and present a number of different strategies for implementing ESG issues in the investment process.Method: This study aims at providing an understanding of a phenomenon which implies an inductive approach. This thesis applies a qualitative method of data collection in the form of semi-structured interviews. The sample in this study consists of venture capital companies that were members of the SVCA (Swedish Venture Capital Association) during the time of the survey, 2015.Result: The empirical findings in this thesis consist of a presentation of the data that was generated from eleven interviews conducted with eleven different investors in the venture capital sector.Conclusion: This study indicates a lack of written policies regarding internal work with ESG-issues which were offset by the application of the "unwritten" policies. Implementation of ESG-issues during the pre-investment phase was dominated by an avoidance of investments in sectors which lead to a negative impact on society. During the post-investment phase ESG-issues was integrated by monitoring the portfolio companies' operations.

Our bachelor thesis is a visualisation made in 3D-graphics of how the horserace track in Tingsryd perhaps will look like in the future, complete with a miletrack, steeplechase, and other horserace courses. Today, the race track is only in it?s building phase. The inner field-group in Tingsryd needed presentation material to show their eventual sponsors, so they contacted us at Media Technology, and we instantly decided to give their idea a try..

A good power quality can be an important prerequisite to achieve a sustainable society. Scandinavia's electrical system is in many respects superior, and Sweden has a fossil free electricity generation at 97 % and a reliability of electricity distribution at 99.98 %. Meanwhile, the EU has an ambition to expand the electricity market in order to achieve a joint trading business across Europe. This cross-border market will result in a large proportion of fossil energy sources integrated into our electrical system, which also leads to an increased need for renewable electricity production in Sweden. One part of this development is to increase the share of renewable micro generation that is locally or regionally connected to the power grid.

Background: Heart ischemia is a disease affected by behaviour, lifestyle and heredity. The disease is more common in the western world and the number of those who suffer increases. The mortality has reduced thanks to that medical resources and knowledge have approved. Purpose: The purpose of this study of the literature was to find out what patients experienced emotionally at an acute heart attack. Methods: A study of literature where scientific articles has been refereed and analyzed, then resulted into five categories presented in the result.

Idiopathic pulmonary fibrosis (IPF) is a chronic respiratory disease with an estimated incidence of 3-6 cases per 100 000 inhabitants in Sweden. There is no cure for the disease, which inevitably leads to death. A similar disease has been found among terrier dogs, with an especially high prevalence in the West Highland White Terrier (WHWT). Dogs with pulmonary fibrosis become lethargic with exercise intolerance, and in some cases they develop cough and respiratory distress. This thesis gives a brief review of the field of pulmonary fibrosis and presents a method for analyzing surfactant proteins in bronchoalveolar lavage (BAL) in the dog.

The Psychology Driving and Barriers to Skunk Work Projects (referred to throughout this thesis as the paper) represents a study predominantly on Tetra Pak from a selective perspective, the innovators. Innovators both past&present whose initiatives contribute to the well being of Tetra Pak as well as one from Ericsson were consulted. As with individuals, organizations possess definable characters that are influenced by the various stages of their life cycle. Theories of corporate life cycle phases and organizational character analysis were therefore employed to identify and explain organizational barriers to skunk work leaders&managers. Predicated on the Organizational Character Index survey developed by William Bridges PhD (himself a recognized leader in the field of transition management) and administered to sixty-one managers within a Tetra Pak business unit established the benchmark.

Sahlgrenska Academy at University of GothenburgDepartment of Clinical NutritionAbstractTitle: The effect of nutritional treatment on functional recovery after stroke, a systematic reviewAuthor: Ingrid Blankenau and Amanda LindbladSupervisor: AnneMarie GrönbergExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTS Type of paper: Examination paper, 15 hpDate: April 13, 2011Background: Every year 30 000 people in Sweden suffer from stroke. This costs society about twelve billion SEK. Many stroke survivors experience functional impairment which may lead to difficulties for them to meet their nutritional needs. Nutritional treatment is important in the recovery process after stroke as malnutrition increases the risk of complications.Objective: To investigate the possible effect of nutritional treatment on functional recovery after stroke.Search strategy: The search was conducted in the databases PubMed, Scopus and Cochrane by using the English keywords stroke, nutrition, rehabilitation, functional outcome, recovery, acute stroke, ischemic stroke, ischemic acute stroke, nutrition therapy, brain hemorrhage, functional recovery and nutritional rehabilitation.Selection criteria: Studies published before 2001 conducted on human subjects who suffer from stroke where they measured functional capacity and did a nutritional intervention, written in English, Swedish or Norwegian, and did not have to be requested from the library.Data collection and analysis: A systematic search was performed in PubMed. Studies which had an interesting heading were examined and abstract read.

En traumatisk kris är en reaktion på en yttre händelse och omständighet. Krisen har fyra faser som de drabbade går igenom, där chockfasen är den första och slutar med nyorienteringsfasen. Studien syftar till att utifrån ett emotionssociologiskt perspektiv studera fyra kvinnliga informanters upple-velser och känslor under och efter en traumatisk kris, som består av kata-strof, dödsfall och sjukdomsdiagnos. Studien söker även svar på hur infor-manternas omgivning, i form av familj och vänner, har agerat i samband med krisen. Genom kvalitativ metod med intervjuer berättar fyra krisdrab-bade informanter om den händelse som utlöste krisen och hur de hanterade detta.

Porcine circovirus type 2 (PCV2) is a common virus present in most parts of the world. PCV2 has been pointed out as the major causative agent to post weaning multisystemic wasting syndrome (PMWS) that affects pigs after weaning. The clinical symptoms of PMWS are impaired growth, diarrhoea, respiratory problems and increased mortality. At autopsy enlarged lymph nodes with depletion of lymphocytes are commonly found. Since 1991 PMWS has spread all over the world and was first described among Swedish pigs in 2003. Although PCV2 is widespread, only some pigs develop PCV2-related diseases. Why this is and what other factors that are required in order for the disease to develop is yet unknown. The main theories involve other infections, for example PRRS, and management issues but also genetic differences between pigs and/or virus strains have been suggested.

Due to the globalization and the changes in the market, companies have now realized the importance of a strong brand. This has led to the phenomena outsourcing. The relation between the branding consultant and his or her client has changed. Earlier the consultants worked as a single unit and were given a task to independently accomplish the assignment. Today there has to be co-operation between the two parties.
