Värme & El med Stirlingmotor
En billig och robust motor av stirlingtyp har konstruerats för användning i
villor. Som energikälla används de heta rökgaserna från förbränningen i husets
panna. Motorn driver en generator i permanent drift under den kalla delen av
året då värme- och energiförbrukningen är som störst i vårt land. Under den
varma årstiden finns den tillgänglig som reservkraftverk.
Tanken är att stirlingmotorns värmare ska placeras i en villapanna för att ta
till vara exergipotentialen hos dess höga temperatur.
Akutsjukvård : cirkulationsrubbningar-symtom, orsaker och åtgärder
The cardiovascular system is one of the three major body systems. When an animal in a critical state arrives at the animal hospital, it is important to know the normal parameters in order to assess the patient?s cardiovascular status. Triage is a process where you considerate the patient?s condition instead of check in time, or other criteria.
Torrgranulering av slagg: Experimentell och numerisk modellering
Vid torrgranulering av masugnsslagg med roterande disk hälls den smälta varma slaggen i en stråle på den roterande disken. Slaggen slungas sedan radiellt ut åt sidorna från disken och sönderdelas till partiklar. Torrgranuleringen bidrar både till att en värdefull produkt i form av cement kan framställas, samtidigt som energin från den varma slaggen återvinns. I dagsläget finns dock inte tillräcklig kunskap om hur olika processparametrar påverkar sönderdelningen och storleksfördelningen av partiklarna för att kunna tillämpa processen inom industrin. Syftet med projektet var att skapa en experimentell och en numerisk modell av torrgranuleringsprocessen med roterande disk för att undersöka hur olika processparametrar påverkar sönderdelningen och storleksfördelningen på partiklarna, samt att utveckla en bildanalysmetod för att validera den numeriska modellen mot de experimentella resultaten.En experimentell modell av torrgranuleringsprocessen med roterande disk skapades i laboratorieskal och förenklades genom att vatten användes istället för masugnsslagg.
The Value of Relationships in a Chinese-Western Business-to-Business Context: An Investigation on Relationship Bonds, Adaptation, Trust and Commitment
The purpose of this study is to improve the understanding of the dynamics behind Chinese-Western buyer-supplier relationships. The study takes on a partially inductive approach by commencing with exploratory in-depth interviews. The main body of the study consists of a cross-sectional survey. Data has been collected through an on-line questionnaire. The theoretical review consists of industrial relationships with specific accounts on the role of adaptation, trust and commitment; a stream of literature in cross-cultural relationships deriving from Hofstede?s culturalist legacy with specific reference to Chinese-Western relationships, including studies on relationship bonding, and the role of guanxi.
Validering inom omvårdnadsprogrammet på tre vuxenutbildningar i Östergötland
This study investigates how social interaction affects newly arrived pupils? views on their study situation in the Swedish educational system. The aim is to give a contribution to the discussion on the notion of including ?the Other? in educational practice in multicultural schools. Semi-structured group interviews were conducted to explore how the intercultural perspective and the theory of inclusion can be used to explain the dynamics of social interaction.
?Vi och dom? : ett fenomen i utlandsstyrkan?
En framgångsfaktor vid internationell tjänst är att samspelet mellan samtliga enheter fungerar friktionsfritt. Detta underlättas om samtliga enheter känner varandra innan rotation till missionsområdet. I framtiden kommer hela förband som har kontraktsanställda soldater rotera ner, dock innehar inteförbanden samtliga funktioner för att lösa alla arbetsuppgifter i missionsområdet. Vid dessa fall lånar man in enheter från andra förband. Inlåningar kan skapa friktioner mellan enheterna.
Att arbeta med Scrum : Påverkan på arbetslag, kommunikation och social miljö
Systems development methods has always been an important part of the systems development process. It affects not only the product, but also the organization itself. Today more and more companies are abandoning the more rigid traditional methods for the more flexible agile ones. A transition like this is bound to affect the product and the organization, but in what ways? Is it a difficult transition to make, and how does it affect social environment and dynamics? Does it change how people communicate information to each other? This study was conducted at a local branch of a larger international IT-company.
?Jag ville faktiskt hoppa av programmet? - Erfarenheter av rasism diskriminering bland socionomstudenter
This study investigates and analyzes experiences of discrimination and racism among social work students, focusing on how these issues occur between peers rather than through hierarchical dynamics, such as interactions with faculty. The research aims to shed light on the academic challenges faced by students with foreign backgrounds, as defined by Statistics Sweden (SCB), particularly those who experience discriminatory practices and behaviors within the academic environment. The study adopts a qualitative methodology, utilizing semi-structured interviews to explore the lived experiences of these students. Participants were selected based on their enrollment in social work programs and their identification as having a foreign background. Data was analyzed thematically to uncover recurring patterns and insights into the participants' experiences.
Nyttorealisering av affärssystem : Microsoft Dynamics NAV vid Statoilstationer i Sundsvall och Hudiksvall
Det övergripande syftet med denna undersökning har varit att undersöka vilka nyttor som förväntas vid implementeringen av ett affärssystem, vilka som realiserats av systemet samt om dessa nyttor har mätts eller värderats på något sätt för att möjliggöra uppföljning av investeringen. Studien har genomförts med en kvalitativ metod och semistrukturerade intervjuer. Respondenterna som har intervjuats arbetar med ett affärssystem i det dagliga arbetet på olika Statoilstationer i Sundsvall och Hudiksvall. Därför har även huruvida de upplevda nyttorna är beroende av driftsform på stationerna, bolagsdrivna stationer och franchisedrivna stationer undersökts. Respondenter från Svenska Statoil har också intervjuats för att få en bild av hur de ser på detta eftersom de tog beslut om att införa systemet på samtliga stationer.
Kampen mot ?machismo?! -en studie av Forum Syds lokala samarbetsorganisationers jämställdhetsarbete med män i Nicaragua
Equality is a central aspect within development work. All development work is expected to be influenced by a gender equalty thinking, and these directions are distributed by the Department of Foreign Affairs, through Sida to Forum Syd and down to the very grasroot level, through Forum Syds local cooperation organisations. The essays question of research is a reflection over empowerment, with other words how international organisations influence other societies understanding of the society dynamics. This aspect triggered my interest for the subject, aswell as the link between aid, equality and men, and how these factors are in need of eachother. My study is mainly build on theoretical starting points, and not on earlier studies.
Uppbyggnad och reglering av en pumpstation till ett injektionssystem
I was assigned to the thesis as part of a project GMA AB (Ground Machinery Applications AB) is running. The project aims to develop a new method for injection of drilled holes in rock walls. Currently, the injections usually involve cement but the basic idea of the project is to replace cement with a supplement called Silica sol.Silica sol is known as a gelling liquid. The gel time is controlled by a mixing of saline. Depending on the amount saline that gets mixed in, the gel time varies.
MIGRATIONSSTYRNING I EUROPA: MAKT, KV?VNING OCH KONTROLL En kritisk maktanalys av migrationsstyrning i Europa genom utrikes f?dda kvinnors arbetsmarknadsintegration i Sverige
In today?s Europe, migration has become a security issue rather than a humanitarian issue.
Previous research highlights how migrants have become prisoners of bureaucracy in Europe
by their mobility being hindered. The present study critically analyses the migration
governance in Europe by highlighting labour market integration in Sweden. The study
highlights migrants with a specific focus on foreign-born women. The research questions
chosen to examine this phenomenon is: How does migration governance in Europe affect
member states' policies for labour market integration, with a particular focus on Sweden?
How do foreign-born women in Sweden experience labour market integration processes
within the framework of the governance mechanisms that exist in Europe? Foucault?s theory
of power and the theoretical concept of choking composes a theoretical framework which is
used to analyse focus group data and text analysis data.
PR i det dolda : en studie om Redaktionell PR
The fashion industry is a line of business which is characterised by tough competition. Often the consumer target groups exposed to advertisements identify them as attempts by the fashion industry to persuade them. When this happens, the consumer disregards the information due to selective attention. Faced with these conditions, companies need to find new, creative ways to market their product lines. This essay is about Public Relations, in particular Public Relations that appear in editorial spaces.
Geopolitisk dynamik : Ett teoriutvecklande anspråk
In the social sciences, geopolitical theory is used in order to analyze states actions and commitments when it comes to foreign policy. This thesis develops a new understanding of geopolitical theory. Firstly, the development and application of geopolitical theory, from its foundations in the early twentieth century to contemporary geopolitical studies is discussed. Secondly a revised understanding of the variables integrated in the concept and how it can be operationalized as an analytical tool is presented and tested empirically.The critical assessment of the research field of geopolitical theory tells us that six different geopolitical perspectives have been considered the most influential (room, strategy, power projection, identity, affiliation and governance) when it comes to analyzing state action. This model is applied as an analytical tool and thus tested on a single case.
Price transmission dynamics of Chinese ADRs listed on the NYSE
Purpose: This study aims to examine the price transmission among ADRs (American Depositary Receipts) and their underlying shares, US market index and Hong Kong market index. We will attempt to capture how a shock in the home market is transmitted to the foreign (and vice versa). In addition we will attempt to assess the relative weight of each variable in the system generating unexpected variations of its own and other variables and at what speed the shocks are absorbed.Methodology: ADF unit root test, Johansen?s co-integration test, Granger causality test, VECM, impulse response, variance decomposition Empirical foundation: Five Chinese ADRs listed on the New York Stock Exchange. Each ADR represents a specific industry.
