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.

The demands of environmental effects in today?s companies have been increasing more andmore. To be able to withstand customers, cooperatives and government demands the ISO14001 certification should not be neglected.In January 2007 the general management of SAS decided to introduce an environmentalmanagement system for SAS Tech.

The aim of this Bachelor?s thesis is to find out what librarians think about the public libraries? collections. How do they want to develop their collection and what do they want the collection to offer society?Sanna Talja has developed a theory about different attitudes regarding collection development. These are named ?the general education repertoire?, ?the alternative repertoire? and ?the demand repertoire?.

Celiac disease (CD) is an autoimmune disease, induced by an immune mediated reaction in the small intestine after ingestion of gluten and related prolamines. There is a strong genetic linkage and most important are the genes that encodes for HLA-DQ2 and HLA-DQ8. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) has developed new guidelines for investigation of CD in children and adolescents, which include genotyping for HLA-DQ2 and HLA-DQ8. Therefore, the clinical microbiological laboratory in Västmanland wants to introduce a method for analysis of these genes. Microarray is a newly developed method for determination of the alleles HLA-DQA1 and HLA-DQB1 that encodes for the ?- and ?-subunits of the HLA-molecules.

The aim of this thesis was to understand and illuminate how readingpromotion projects can be carried out, what sort of activities they mightcontain and what sort of lasting impressions they might make. We choseto examine reading promotion projects because we consider thepromotion of reading and literacy a vital and important part of thelibraries work. The study took place at the city library of Uddevalla andthe projects included in the study were all directed towards children andyouth.The theory used in the thesis was Aidan Chambers?s model of theReading Circle which consists of the four themes of selection,?reading?, response and the enabling adult. Methods used were semistructuredinterview, document studies and observation.The results show that reading promotion projects benefit from cooperationbetween the adults involved and that education of the adultsin order to indirectly target the children is an effective way of spreadingthe love of reading.

Occupational stress and the use of alcohol to reduce stress are both separately common in our society. A few researchers have combined the two factors.The aim of this essay was to obtain an increased understanding of how male and female managers estimate their alcohol habits in relation to their occupational stress.We have interviewed nine managers who work at a social services department in Scania. Our main theories were the theory of psychosocial work environment of Lazarus, Karaseks demand/control model, epidemiology- and cultural perspective.Our results were;· Psychosocial work environment contributes to if the interviewed people experienced stress at work.· The grade of control has great influence if the interviewed people experience stress.· There weren't any correlation between stress and increased consumption of alcohol..

This master thesis deals with the theme of memory, it is through an artistic process I have investigated and peeled off to a specific memory, the hut. It is in the work of the personal memory through a craft process it transforms into something public. The hut is constructed out of corrugated boxes, corrugated boxes casted in clay. To cast an object differs according to me from sculpting the object; it is the function rather than the sensual feeling that is sought after. It is about the clarity and accuracy through the casted object that suggest something vague and indeterminate.

This thesis considers the use of an oldrock cavern as thermal energy storage.With a large system of differentchillers a model was created to find anappropriate future system. There aremainly two trajectories to take. Eitheran installation of chillers needs to bemade or the rock cavern can be used tomeet the future demand of districtcooling in Solna, Sweden. Additionallythis thesis investigates the possibleuse of different techniques to utilizethe phase change energy of water.Simulation shows that it?s possible toutilize the phase-change energy of afluid; however it?s not economicallyfeasible due to the thermodynamiceffects on the Carnot cycle.

Our study aims to examine whether managers in elderly care are working from a salutogenic approach to create a dignified life for the residents. By this we are trying to find out how you look at life in dignity and what meaning it has, what similarities and what differences there are. We also want to explore what they want to achieve with their work and what they do to enable it. The questions we asked ourselves what the salutogenic approach is for managers working in nursing homes. How do they look at a decent life and we ask ourselves the question of the salutogenic approach is just a "buzzword" in a working man always had or there are real differences? The method we have chosen to use is a web-based questionnaire that we sent to our sample.

The thesis of this essay is that the concept of governance is a product of the neo-liberal dominant ideology and that the implementation of governance ideas will lead to a weaker nation-state. Using critical theory the essay constructs an ideal type of neo-liberalism and compares its core values with these of the governance concept as treated by the main literature in the area. The essay then focuses on the issue of the state, and discusses whether the changes leading to a demand for governance have actually weakened the state. Furthermore, the essay presents the practical use of the term governance in the EU and Sweden and problemizes the changes that the neo-liberal domination has led to in terms of power and democracy. Finally the essay discusses alternative views on the changing role of the state.

The possession over bills and coins has, on the whole, been replaced with a credit balance on an account. Almost all payments today are processed by transmitting digital data and not by using cash. The credit balance on an account is a demand that the holder ofthe account have towards his bank. Law regarding three part relationships: By using Göranson?s theory you can say that the credit balance on an account may be object of possession.

Society?s interest for environmental issues was reinforced in the 1960:s when the book by Rachel Carson, ?Silent Spring?, came out. She described a picture of a world without birds singing and this got the environmental debate going. Today, this debate has reached the corporate world since stakeholders are putting pressure on companies to show greater environmental awareness. Many companies show uncertainty when they are faced with these new market demands.

Background: In studies about Romani people?s health, it becomes clear that the Romani inseveral countries have a poor health and avoid seeking health care.Objective: The purpose of this study was to explore Romani men's experiences of treatmentin the Swedish health care.Method: A qualitative interview study was conducted with respondents about theirexperiences in individual interviews. Seven male Romanis were elected with a purposefulsample. A content analysis by systematic text condensation on the data obtained was made asdescribed by Granheim & Lundman (2004).Results: The summed up impressions of the responses was perceived to be good, however,many men believe that the information is inadequate. Staff at the emergency department inUppsala should listen more to patients.

The aim of this qualitative study was to examine six individuals' experiences to talk about the sexual abuse that occurred in their childhood. We interviewed five women and one man, using a phenomenological approach during the work process. The theories emerged as we analyzed our results and appeared to be communication, cognitive theory, validation, trauma theory and taboo. The results showed that the respondents, whom disclosed the abuse as children, were most likely to get a negative response from both formal and informal support systems. While as adults they were confirmed to a greater extent and therefore achieved a better physical and mental wellbeing.
