ATP bioluminescence to establish a test procedure for hygiene testing of liners and tubes on farm level : an investigation of the effect of ageing on the hygienic status of rubber liners and tubes

When rubber equipment in a milking system ages, physical and chemical deterioration occurs and cracks, crevices, as well as deposits of organic and inorganic material is formed on the surface. Bacterial colonization can accumulate, especially on ageing rubber equipment and if the cleaning procedure is not functioning properly. Formation of biofilm in milking equipment could in turn cause bacterial contamination of bulk tank milk. ATP bioluminescence is a fast and easy way to determine the hygienic status of a surface based on its ATP content, and results are given in relative light units (RLU). The method measures both bacterial contamination as well as residues from other organic material.

Portning och utökning av processor för ASIC och FPGA

In this master thesis, the possibilities of customizing a low-cost microprocessor with the purpose of replacing an existing microprocessor solution are investigated. A brief survey of suitable processors is carried out wherein a replacement is chosen. The replacement processor is then analyzed and extended with accelerators in order to match set requirements.The result is a port of the processor Lattice Mico32 for the FPGA curcuit Xilinx Virtex-5 which replaces an earlier solution using Xilinx MicroBlaze. To reach the set requirements, accelerators for floating point arithmetics and FIR filtering have been developed. The toolchain for the processor has been modified to support the addition of accelerated floating point arithmetics.A final evaluation of the presented solution shows that it fulfills the set requirements and constitutes a functional replacement for the previous solution..

Fördröja åldrandet av elektrotekniskt papper genom kemikalietillsats : En studie av dicyandiamids påverkan

Nordic Paper Åmotfors tillverkar elektrotekniskt papper som används till att isolera lindningarna i transformatorer. Det är viktigt att bibehålla papprets egenskaper under en mycket lång tid då en transformators livlängd är lång. Syftet med detta examensarbete var att undersöka huruvida tillsats av en kemikalie bestående av dicyandiamid kan fördröja åldrandet av de papper som Nordic Paper tillverkar. Förhoppningen var att deras papper därefter skulle klara de krav-parametrar som finns för papper som åldrats i olja. Kemikalien som användes var Cartafix® WE liquid.Försök utfördes där olika kemikaliedoseringar tillsattes i mälden.

GPU accelerated SPH simulation of fluids for VFX

Fluids are important to the Visual Effects Industry but extremely hard to control and simulate because of the complexity of the governing equations. Fluid solvers can be divided into two categories, those of the Eulerian point of reference and those of the Lagrangian. Both categories have different advantages and weaknesses and hybrid methods are popular. This thesis examines Smoothed Particle Hydrodynamics, a Lagrangian method for physically based uid simulations. To allow the artist the exibility given by shorter simulation times and increased number of iterations, the performance of the solver is key.

Leka lära leva : En studie i inomhusmiljöns betydelse för små barns lek och lärande i förskolan

Our aim in this work has been to redesign ModernFamilies and make a user-friendly interface for people with aphasia. The focus has been to identify general issues they might face while using different technology and applications, in order to find better alternative design for ModernFamilies, with a focus on usability. To approach this issue, we used a qualitative method. Our study includes several interviews and observations preformed in conjunction with the AGNES project (AGeing in a NEtworked Society) and speech therapists. Aphasia requires simple design that in the same time gives them support to understand and use technology and different applications.

Organisationsförändring ? hot eller utmaning

Working life changes, just like the rest of today?s society, at an accelerated pace. It is through changes and challenges that human beings develop, personally and professionally. Changes are often met by resistance. The purpose of this study is to see how different factors influence individuals? experiences of change.

Seniorers motivation till motion : En kvalitativ studie om seniorers strävan mot ett aktivt och friskt liv

This qualitative study investigated what factors influenced older adults to motivate themselves to continue to be pshysical active in their later life. Six individuals, both men and women in the ages of 65-89, were interviewed. The interviews were analysed by informal content analysis. The results showed that there is a certain group who had a strong will to lead a long, well-conditioned and sound life. Although, the seniors are getting older, they continue to make active choices about physical activity on a daily basis.

Klassificering och värdering av finansiella instrument : Ett tillförlitlighetsperspektiv

During the financial crisis voices were raised towards the regulatory framework IAS 39 recognition and measurement of financial instruments and pointed out that it was inadequate. The complexity of the framework contributed to the fact that it was difficult to apply. IASB accelerated the modeling of the new to be regulatory framework IFRS 9. In this study we will focus on the reliability of accounting information, which is an important aspect from the stakeholder?s point of view, for example, to be able to make the best decisions the accounting information should be proper.

Aktivt åldrande : att styrketräna som pensionär

The essay is about pensioners who are working out at a gym. My starting point is the research program "Culture of ageing? and the theory that pensioners in the post- and late modern society conquer new potential areas. I am studying the meeting between pensioners and the gym. How the pensioners conquer the gym, relate to their training and what makes them stay after the first introduction.

Ett samspelt Samhall? En studie av ett avkastningskravs inverkan på en organisations interna styrning: A synchronized Samhall? A study of the impact of an imposed return-on-equity requirement on the management control mechanisms of an organization

The aim of this study is to examine and analyze how management control mechanisms evolve within an organization when a requirement of return on equity is imposed, as well as why the mechanisms evolve the way they do. A case study was performed on Samhall, a Swedish state-owned company, which has the aim to help people with disabilities develop by providing meaningful work. The framework provided by Samuelsson, defining five means of control in organizations was used to structure the study. Further, theories within New Public Management have been used to provide the reader with a proper background to the research area. Theories from the institutional field of organizational research have also been used to provide further depth to our analysis.

Mitt hem det är allt det : En kvalitativ studie om hemtjänstmottagares syn på hemmet, åldrande och hjälpberoende

AbstractThe intention of our study was to examine the meaning of home of elderly women and men and how they experience their getting older. We also wanted to see how elderly women and men experience to receive home-help-service in their own home. The study was based on qualitative interviews with elderly women and men. The informants were five women and four men between the ages of 60-84 years. They all had everyday help from the home-help-service.

Jag trodde aldrig det kunde vara så bra att vara pensionär : En intervjustudie av äldres tankar kring åldrande och livsstil i ett seniorboende

The aim for this thesis is to illuminate expectations and conceptions of senior housing from an individual perspective of seniors and how senior housing is put in relation to the process of ageing. Safety, community and accessibility are main notions for the seniors and therefore also in this essay. The method used for writing, analysing and interviewing is Grounded theory, with basis from social constructionism. Theoretical background comes from theories developed in social gerontology and gerotranscendence. These theories helps to give perspective to the analysis of the interviews.
