Termoelektrisk lagring i system med fjärrvärmeproduktion
With increased deployment ofintermittent renewable energy, such aswind and solar power, energy storagebecomes necessary to help reduceproduction peaks. Thermoelectric EnergyStorage is a method still in researchphase, which stores electricity in hotwater at a temperature of 120 ° C. Thisthesis aims to examine whether theThermoelectric Energy Storage would bepossible to integrate into existingpower generation such as a combined heatand power plant, and how the technologypotentially could function in theelectricity market. ThermoelectricEnergy Storage consists of a chargingprocess and a discharging process, bothoperating by the working fluid CO2. Toincrease the efficiency of theThermoelectric Energy Storage, wasteheat from the district heating networkis integrated.A model of the Thermoelectric EnergyStorage has been developed and it wascalculated by thermodynamic propertiesof the working fluid, CO2, in thevarious process steps.
Delegationsdemokrati - En studie av Hyresgästföreningens förhandlingsdelegationer
The aim of this essay is, with reference to a close study on the negotiation delegations of the Tenant Association, to examine the principals of democracy in relation to distribution of power and participation, efficiency and professionalism. This is done with the intention to understand the Tenant Association's view on its own commission as negotiator, according to democracy. The investigation is carried out on the Tenant Association in the Swedish cities of Stockholm, Malmö and Gothenborg.The data acquisition was obtained by using a questionnaire and through interviews with representatives from the Tenant Association negotiation delegation.A central conclusion from this investigation is that the representatives of the Tenant Association generally are satisfied with the democracy model used in the organisation, despite awareness of the fact that there are some failures with representation amongst younger people, women and immigrants. Also, they suggest that the model with representative democracy is by all means the most useful because of its arrangement and efficiency in decision making processes.The policies of the Tenant Association, considering distribution of power and participation between elected representatives and employees, are legitimated by the negotiation delegates. However, there is obvious discrepancy in the look upon their respective tasks between the delegates and the chief negotiators.One can recognise the development of democracy that is called New Public Management in this survey.
Postmoderniteten i Svenska kyrkan. En läsning av herdabrev 1972-2014
The purpose of this paper is to explore to what extent some Swedish bishops (1972-2014), mainly archbishops, were influenced by postmodernity as described by Lyotard in his report La Condition postmoderne (1979).This report had a tremendous impact on the western cultural and philosophical debate in general during the very end of the twentieth century. I am trying to find out if this impact could also be observed in the religious sphere and particularly in the Church of Sweden. My theory used, is mainly based on the ideas presented in La Condition postmoderne and my method is a hermeneutical reading of eight pastoral letters. These letters were written during the time that the Church of Sweden transformed from being an officially recognized national church to a free church among other free churches and in this respect ended to be a part of the official governmental power. The terms postmodernism or post-modernity were scarcely used at all in the pastoral letters but on the other hand the bishops seemed to share many of the ideas that Lyotard presented, such as the view on the metahistory/metanarrative and the connection of knowledge to power, the necessity of dialogue and openness and the importance and the role of creating and maintaining language games..
Integrationens betydelse : En kvalitativ studie om bakomliggande orsaker för aktualisering hos socialtjänsten
Syftet med denna studie har varit att analysera socialsekreterares erfarenheter av bakomliggande orsaker till att barn i familjer med utländsk bakgrund blir aktuella för utredning enligt Socialtjänstlagen (SFS 2001:453). Studien behandlar skillnader mellan familjer med utländsk bakgrund och familjer med svensk bakgrund vad gäller bakomliggande orsaker för aktualisering hos socialtjänsten. Studien är kvalitativ och grundar sig på fem semistrukturerade intervjuer. Till grund för analysen har Bronfenbrenners utvecklingsekologiska teori använts vilken har kompletterats med begrepp som behandlar migrationsprocess, socialisationsprocess och kultur.Resultatet visar att det inte finns någon större skillnad gällande bakomliggande orsaker för aktualisering beroende på härkomst. Det framkommer att social utsatthet är vanligt förekommande hos de familjer som aktualiseras och då främst i form av ekonomisk utsatthet, boendesituation och arbete.
The hypothalamic-pituitary-adrenal axis and perinatal treatment of premature foals
The danger and vulnerability associated with a preterm birth seem to be closely correlated with a dysfunction of the fetal hypothalamic-pituitary-adrenal (HPA) axis, whose maturation in the foal is without a doubt as delicate as it is important. Not only is this endocrine cascade
vital for the foal in order to cope with neonatal stress, it also appears to be fundamental for the final fetal intrauterine maturation, as well as for the onset of foaling.
Equine gestation exhibits some rather unique features, indicating a somewhat different significance of the endocrine changes associated with HPA maturation, compared to many other species. This hormonal cascade is rapid and confined to a narrow time during late gestation in the horse, and the risk of the foal completely missing it therefore becomes prominent.
Induced parturition in the mare may be operated through uterotonic agents, which occasionally bring about premature foals. Desirable seems the ability to initiate equine labour
while simultaneously enhancing fetal HPA maturation, as in humans and ruminants through perinatal glucocorticoid administration. However, similar treatment in the horse has resulted in various, sometimes fatal, outcomes.
In the light of the distinctive features of equine gestation, difficulties are encountered following such administration of glucocorticoids and ACTH.
Towards an Understanding of Heterosexual Risk-Taking Behaviour Among Adolescents in Lusaka Zambia
This thesis investigates the underlying factors behind sexual risk-taking and non-risk-taking behavior with regard to Sexual Reproductive Health (SRH) among adolescents in Lusaka, Zambia. The Qualitative Approach was used for data collection and analysis and using the theory of Social Construction, the author explains how different contexts and aspects in the Zambian Society, that is Traditional, Socio-economic, Political, etc., influence the sexuality or sexual behavior of young people in Zambia. Hermeneutics was used to interpret the meanings in the texts/transcripts acquired through data collection and from the author?s knowledge and understanding of the Zambian historical and cultural contexts within which the participants of the research were constructed. Max Weber?s Ideal Type concept was also used to explain that each young individual?s sexual behavior is uniquely constructed by societal aspects.
Voltage Sags Indices and Statistics
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.
Sömn och Powernap - Dess betydelse för återhämtning och prestation
During sleep the majority of the body?s production of anabolic hormones is produced and sleep is a general anabolic state of being. It has been to our recognition that a powernap is 4-6 times more effective when it comes to sleep intensity than the last 1-2 hours of a traditional eight hour sleep. With this in mind, and that elite athletes worldwide often sleeps in between their training sessions. This study has tried to prove a hypothesis which comes from the assumption that you can recover and perform better during times with intensive periods with better distribution of your sleep.We have in this study let three test subjects take part of a six week long program with two different training periods for legs.
Spanjorer är vi allihopa? : En kvalitativ studie av hur spanska och katalanska tidningar identifierar Kataloniens självständighetsprocess.
The Catalan movement of Independence is a well debated subject in Spanish news for the last decade. This thesis aims to examine what kind of identityarguments that spanish versus catalan newspapers make about the independence movement, in relation to nationalism and national identity. This is to deeper the understanding about the current complex situation in the Iberian Peninsula. The research shows that identityarguments about the independence movement presented by catalonian newspapers clearly put focus on identifying the ethnic and cultural reasons for the growing nationalism in the region, as well as discussing the political possibilities and obstacles of a sovereign Catalonia. In comparison, the identityarguments presented by spanish newspapers has another view of the situation, where the political aspect of the nationalistic catalan movement, identify the process as defying the Spanish Constitution and challenging the traditional historic unity of Spain.
Business Intelligence inom humanitära organisationer
Several studies has identified the locker room experience as a potential deterrent for participation in physical education. Both psychological and physical issues arise due to several factors. Psychological issues include different kinds of verbal and physical violations, comparisons between pupils, feeling of vulnerability along with a stressful schedule. The physical environment can contribute to negative experience for pupils in terms of filthy premises and cold showers. These factors may contribute to higher absentee rates in physical education.
Den nya skollagen och skolorganisationen i Malmö stad : en kvalitativ undersökning om skolkuratorernas upplevelse
The purpose of our studyis to investigate how the changed Education Act in Malmoe affects the work of school counselor in elementary school and how it further may affect the work. We were also investigating counselors? views on the politically increasing transparency of student health that comes as a result of the new school organization in Malmoe. To obtain our results, we have chosen to use a qualitative research interview, where we have chosen a semi-structured interview form. We have chosen two theories, Foucault -power and discipline and organizational theory.
Flygbesiktning av Luftledningar : Modellering av samband mellan besiktningsanmärkningar och systemtillförlitlighet
This paper thoroughly investigates needs and requirements for overhead distribution feeder inspection and develops models to investigate possible relations between short term inspections remarks and outages. The study was conducted in collaboration with Fortum Distribution AB that supplied extensive information about their overhead power feeders concerning both inspection and power outages. The investigated models where lognormal linear model, Poisson generalized linear model and negative binomial generalized linear model. All models were implemented utilizing offset terms to compensate for differences in feeder length and amount of overhead versus underground feeders. The Poisson generalized linear model was rejected at an early stage due to overdispersion and neither of the remaining models fit the data perfectly.
Klassningssällskapens regelverk, ett möjligt verktyg för att skapa stryktålighet på örlogsfartyg?
I denna uppsats behandlas hur klassningssällskapens regelverk kan bidra till ett örlogsfartygs överlevnad vid vapenverkan. Syftet är att undersöka om regelverken kan användas för att implementera stryktålighet genom sina notationer och krav på redundans, separation och skydd mot splitter.Arbetet inleds genom kunskapsuppbyggnad av teorier som behandlar örlogsfartygs överlevnad, vilka sedermera bildar arbetets teoriram. Sedan sker en analys av regelverken samt en fiktiv operativ miljö skapas för att ta fram taktiska uppgifter samt hot, vilka sedan omvandlas till verkansdelar och kritiska system. Därefter skapas modellerna som tillsammans med verkansdelarna används i simuleringen som genomförs i simuleringsverktyget Semiautomatsikt fartygs verktyg för AVAL. Simuleringarna mäter utslagssannolikheter av olika funktioner ombord vid påverkan från de framtagna verkansdelarna.
Genusperspektiv vid högläsning : Fyra pedagogers erfarenheter
This study is conducted from qualitative research with interviews as a basis, where I have interviewed four teachers from elementary school?s early ages (year 1-3). The aim is to highlight the teacher?s perspectives and experiences of reading aloud, and how they connect the activity to gender.The questions at issue that have been answered in this paper are how the teacher?s reflect to gender and reading aloud in a school environment; do the teacher?s reflect over the gender perspective when choosing reading aloud literature? When reading aloud, which attributes are important to highlight for girls and boys according to the teachers? Which books do the teachers consider "good" gender literature?The paper is based on the theoretical grounds of social constructivism, gender as construction, gender conscious pedagogy and reading aloud. In previous research the focal point has been Kåreland?s study on gender in literature in pre-school, and on how children are being portrayed in children?s literature today, from a gender perspective.The teacher?s that have been interviewed in this study all agreed on the fact that reading aloud is a very important part of education and are used by most teachers on a daily basis.
Konstruera och rekonstruera traditionell kunskap - en diskursanalytisk studie av texter om internationellt utvecklingsarbete
The master's thesis investigates how the concept traditional knowledge is represented by international organizations that are influential in development work and policy making. Departing from a theoretical framework drawing on Michel Foucault, constructed aspects of knowledge and the power relations knowledge production implies are highlighted.A recent interest within library and information science and practice to document this kind of knowledge raises questions about how traditional knowledge differs from other forms of knowledge and how knowledge organizational tools can be applied. Investigations, which critically explore the concept traditional knowledge, the power relations the concept creates as well as the interests and purposes it serves, have been surprisingly absent within the discipline. The focus in this master's thesis is how traditional knowledge is conceptualized by international organizations. A discourse analytical approach reveals the power relations that are inherent in their descriptions of traditional knowledge and how they describe the relevance of the concept for their work.
