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.

Interdependence between seed age and aerated steam treatment intensities

Aerated steam treatment is a modern and environmental friendly method for seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between seed age and the aerated steam treatment intensities. Two studies were carried out in this thesis. In the first study the storage longevity of seeds treated with aerated steam was examined. The second study investigated the shelf-life of the pre-tests used to determine the aerated steam treatment tolerance of a seed lot, by testing the treatment tolerance of seeds aged prior to the treatment.

Pensionärers identitetsskapande i åldrandeprocessen

The study investigated pensioners? forming of identity during the ageing process and the correlation between norms and identity. Previous research has shown that there are norms and notions about elderly and what growing old well implies. There is missing research on the level of the individual with norms, ageing and the process of identity formation. There is a large population of pensioners in Sweden and the authors behind this study wish that the results of it will help study counsellors to approach pensioners? in a norm critic way.

Ensamkommande barn i vuxenlivet : en kartläggning om ensamkommande barns etablering i samhället

The paper aims to examine how well a small group unaccompanied children have established themselves in Swedish society. In order to determine how well they have established the empirical material which is primarily based on quantitative data has been measured with a theoretical model developed by the theorists Nancy Fraser and Alistair Ager and Alison Strang. Based on the theoretical framework the unaccompanied children establishments have been measured in example income, education, debts with Kronofogdemyndigheten and social network. It was found that the unaccompanied children had not achieved the establishment in the society that was expected from the theoretical framework. Their results were also generally below the national average for young adults in Sweden who are the same age.

Äldres berättelser om åldrandet

ABSTRACT Our main objective with this essay is to provide a description of old people?s stories about aging. The essay is based on the empirical source of four qualitative interviews with older people over the age of eighty years young. The main goal is to inquire answers about; their time in the workforce; retirements; healthissues; media/advertisements; adolescence/youthfulness and attitudes. The following main questions have been dealt with: What do the elderly emphasize when they describe ageing? Are healthissues the prime subjects the elderly talk about? Do the elderly experience positive or negative attitudes towards ageing? What is their point of view of younger generations? In what way do they describe their years as workers? In what way do they describe aspects about their retirement? We reserved to consider the opinion of their own, to be the most valuable source in our study.

Den åldrande hästen

SammanfattningDetta arbete tar upp de viktigaste fysiologiska förändringarna hos den åldrande hästen, hur dessa påverkar hästens beteende och behov, och hur det i sin tur påverkar den omvårdnad hästen har behov av. Sjukdomar som i större utsträckning drabbar äldre hästar än yngre tas upp, och fokus ligger främst på att så långt det är möjligt förebygga dessa. I de fall detta inte är möjligt ligger fokus på att göra livet för den sjuka hästen så symtomfritt som möjligt. Den åldrande hästens näringsbehov tas upp, samt hur detta kan påverkas av olika sjukdomar. Med åldrande hästar menas i detta arbete hästar i åldern 20 år och uppåt.SummaryTreating older horses for illness and injury becomes more and more common.

Medborgarskap i daglig verksamhet : En jämförande analys av identitet och deltagande

The aim is first to identify concept of citizenship and the dimensions of the same, in the political science theory, which can be crucial, to that a citizenship may be found available for people who have a cognitive delay. Thereafter examine the prevalence and significance of these, in policy documents from two different organizational forms, through an analysis, in the form of a discussion, on the basis of political science theories in the field. The study's aim in a reflective way, highlighting key requirements for an accessible citizenship for the target audience, and thereby clarify the priorities in daily activities that can support an emancipatory citizenship process for people who have a cognitive delay..

Den åldrande befolkningens hot mot välfärden - En politisk myt i väst

The purpose of this thesis is to expose the political myth in the West about the ageing population seen as a threat against the welfare society. To do so I have described what a political myth is, and showed how it is presented in the most influential newspapers and organisations in the West. I have also presented alternative perspectives to the dominating view on the ageing population and it's impacts on welfare. In this way I have tried to point out that the subject has a political dimension. In the thesis last section I compare the message presented in the newspapers and the organisations with the characteristics of a political myth.

Spatial TDMA in Ad Hoc Networks with Antenna Arrays

In modern military operations the requirements of transmitting large amounts of information have increased substantially during the last decade. This increases the demand for high-capacity radio networks. It is also very important that military decisions are made on recent and correct information and this implies that low and known delays are required. The existing military radio ommunications, within the Swedish army, do not meet the requirements for capacity and delay. We have investigated how the capacity and average delay can be improved in an Ad Hoc network with STDMA by using antenna arrays.

Öppen dagvattenhantering i urbana miljöer :

Storm water causes a number of problems in our country, particularly in city environment with its surfaces of non-absorbing ground materials. At heavy rain falls there are floods due to lack of capacity in the drain system when meeting heavy water masses over a short time. When the drain system is overloaded huge water masses reach the recipient untreated and there causing disturbances in the aquatic ecosystem. Due to emissions from mainly traffic, industries and other human activities the storm water is polluted. Earlier the problem used to be solved technically, by increasing the capacity of the tubes and by construction of reservoirs to delay the floods peaks.

Lastbalanseringsalgoritmer : En utvärdering av lastbalanseringsalgoritmer i ett LVS-kluster där noderna har olika operativsystem

Denna rapport behandlar en undersökning av olika lastbalanseringsalgoritmer i Linux Virtual Server. Undersökningen har gjorts i ett webbkluster (Apache var webbservern som användes) med tre heterogena noder, där operativsystemet var den detalj som skiljde dem åt. Operativsystemen som ingick i undersökningen var Windows Server 2008 R2, CentOS 6.2 och FreeBSD 9.0. De faktorer som undersöktes mellan de olika algoritmerna var klustrets genomsnittliga svarstid vid olika belastning och hur många anslutningar som kunde hanteras av klustret, detta gjordes med verktyget httperf.Undersökningen ger svar på hur ett heterogent webbklusters genomsnittligasvarstid och arbetskapacitet kan skilja sig åt beroende på vilken algoritm som används för lastbalansering. Resultatet visar att den genomsnittliga svarstiden håller sig låg tills en hastig stigning inträffar.

Analysis of Quality of Service of Wireless LAN for IEEE 802.11e

Nowadays Wireless LAN is playing a more and more important role in network systems. After 1999, in which the IEEE organization published its Wireless Local Network standard 802.11[1], many people saw the advantages of the standard but also the lack of support for multimedia streaming. A lot of research work has been done on the proposed IEEE 802.11e standard draft during the past 4 years. It is supposed to be able to fully support Quality of Service. The final version will be published early in 2004.

Eftersökta fördelar vid företagsförvärv : integrationsprocessens betydelse för måluppfyllnad

Mergers and acquisitions are a phenomenon which can occur for a variety of reasons. It may for example be that the organizations want to gain larger market shares or to complement and learn from each other and thus become more competitive. After the completion of an acquisition or merger, a process is initiated to create an affiliation between the two companies' employees. The purpose of this paper is to examine whether there is something that management can do to make the integration process as efficient as possible. The empirical research in this paper consisted of interviews and surveys with respondents from two accounting firms that recently completed a merger.
