Kulturella värden, tro, levnadssätt och livsstil : faktorer som påverkar sjuksköterskans möte med muslimska patienter
There are over 1,5 billion Muslims living on earth and the religion is one of the world´s most increasing. Sweden is a country with a cultural diversity where about 300 000 Muslims lived in 1999. Today, the requirement for knowledge about caring for Muslims and the need of culturally competent nursing care are increasing.The aim of this study was to define cultural factors which the nurse has to recognize to be able to give culturally competent care to the Muslim patient. The method that has been used was a The Sunrise Model, which illustrates Leininger´s theory of culture care diversity and universality, provides a theoretical framework for the study. The results are presented on the basis of Leininger´s three cultural factors; cultural values, beliefs and lifeways.
Materialvagnstransport
A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.
Hampa i det svenska textilarvet : en studie i hur historia om textilföremål arrangeras i mellanrummet mellan natur och kultur
This essay is about the Swedish textile heritage but also with an analysis of handmade hemp textiles from Transylvania. Plant fibers such as hemp and flax grown in a soil nature that existed around the subsistence farm. The knowledge of the earth nature combined with textiles has not been specifically studied in the research from the last century. By examining simple folk textiles of hemp shows how the textiles also are an universal field. The focus is on the raw material which is a transformation between nature and culture.With a phenomenological approach, the study will describe how the textile heritage announcement molds a territory in the interpretation of "our" Swedish plantfibres for textiles uses.
Tro och vetande : om evolution och kreationism i skolans biologiundervisning
The purpose of this essay is to study the public debate on the subject of creationism, the belief that there is a creator of all life on earth. The study is focused on creationism in different forms in schools and the more general discussion of creationism as an alternative to the theory of evolution. The overall question is what should be taught as the origin of life: Evolution or creationism in various shapes and forms? The essay consists of an overview of previous research in both the USA and Sweden, and an analysis of argumentation on the issue in newspapers. A comparison is made between the USA and Sweden.The analysis of newspapers shows that there are some arguments for different forms of creationism but there are considerably more arguments against creationism.

Strömkontroll till aktiva magnetlager med noggrann och störningsreducerad strömmätning
There is always a need for more effective ways to store energy in order to reduce the human impact on the environment. One step on the way can be the use of flywheels as kinetic energy storage devices. Low frictional losses are essential for a flywheel to be effective. To minimize these losses active magnetic bearings (AMB) can be used to keep the shaft centered instead of the more conventional ball-bearings. AMBs use actuators and a fast control system that needs correct and noise-free measurement data of the shaft position and the current in the actuators to work properly.This thesis explains the process of constructing power electronics and a current measurement system for active magnetic bearings (AMB).
Kostförändring och/eller fysisk aktivitet vid fetmabehandling
The aim of this study was to investigate whether a dietary change, physical activity or a combination of both gave the best result when treating obesity, concerning weight loss and BMI. Excessive weight and obesity are today a big health-issue and it is estimated that 10 % of the men and 12 % of the women in Sweden have a BMI over 30, i.e. are suffering from obesity. The corresponding number for children is 3 %. No one can say for sure what causes obesity but there are many theories.

Uppgradering av styrsystem och en operatörspanel för en centrifug
Examensarbetet har gått ut på att uppgradera ett styrsystem och en operatörspanel för en centrifug i en kemisk industri. Projektets syfte är att centrifugen ska köras på ett mer automatiskt sätt med ett nyare system som har större tillgång till reservdelar. Centrifugens äldre styrsystem från Siemens har bytts ut mot ett nytt Siemenssystem och den tidigare operatörspanelen från Siemens har bytts ut mot Beijer Electronic E1070 operatörspanel. Styrsystemet programmerades sedan i Siemens Simatic Step7 och operatörspanelen programmerades i Beijer Electronics E-designer. Efter att programmeringen var klar testades kommunikationen mellan styrsystemet och operatörspanelen innan inkopplingen av det övriga systemet skedde.
Kontext, utvärdering och användarupplevelse : En studie om kontextens påverkan på användarnas respons vid utvärdering av användarupplevelse
In this paper we explore the relations between context and feedback generated in three user-centered evaluations of a flash-based game. Whether it?s the social context, the physical context or the degree of intrusion from the evaluator, they all contribute to the quality of the feedback received. The selection of test subjects is a narrow process, which gives the above mentioned factors different meaning. Contextual factors have shown to influence the feedback given within both usability and user-experience.
Das Experiment : -ett försök att skapa den passiva studentbostaden
Byggandet av passivhus har ökat kraftigt under 2000-talet i Sverige. Dock har det inteutformats och byggts några studentbostäder i passivhus form ännu. Denna studie går ut påatt försöka utforma studentbostäder som uppfyller de svenska kraven för passivhus. Genomatt välja ut lämpligt material och komponenter, t ex. väggtyper, platta på mark ochfönstertyper redovisas olika beräkningar för energiförbrukning.I metoden till beräkningarna som genomfördes, där resultaten hamnar i jämförelse medvarandra, användes VIP-energy samt PHPP.
Matematiska utmaningar i grundskolans tidigare år : En studie om hur elever med särskilda matematiska förmågor identifieras och utmanas i grundskolans tidigare år
I denna rapport undersöktes S&P 500 Energy Index genom multipel regressionsanalys. Modellerframställdes genom regression och baserades på data hämtad från börsen. Modellerna angavs iprocentuell ändring respektive absolut ändring. Validitet för varje enskild kovariat testades och en risknivå avgjorde om en kovariat skulle inkluderas i modellen eller inte. Detta ledde till två modeller med bättre kurvanpassning till den givna mängd data över det valda energiindex.
Minikartor : Kartors spelarpåverkan
Undersökningen har ämnat svara på hur en spelares spelupplevelse i och uppfattning av en bana i ett spel förändrats när spelaren haft en karta mot när den inte haft en. Genom att konstruera en bana med karta och ?minikarta? undersöktes spelarens spelupplevelse och mentala modeller på banan. Undersökningen skilde dels på personer med spelvana och personer utan spelvana, dels på spelare med kartor och spelare utan kartor. Tillgången till karta visade sig knappt ha påverkat spelupplevelsen alls.
Värdet av demand response på den svenska elmarknaden
Intelligent IT-based solutions, often called Smart Grids, are considered to be the future balancers of renewable energy sources. One area within the Smart Grid concept is called demand response, which is focused on making customers more consumption flexible by making them more active in their consumption. In this thesis the aim is to analyze a business model by investigating the income potential for a demand response solution as well as its market potential. This has been done through literature studies, interviews and development of a computational model.The use of 5000 households with flexible consumption can provide a cost reduction of 17.2% or 2.4 million SEK for a balance responsible party during an average year. If the solution is used to make strategic bids on the regulation markets the study indicates that the largest potential for revenues lies within this strategy.
Biogaspotential hos våtmarksgräs
BIOGAS POTENTIAL IN GRASSES FROM WETLANDSMarvin MartinsThe purpose of this study has been to survey wetlands that are suitable for mowing and to analyze the biogas potential in the harvested grasses. A preformed investigation showed that there are suitable wetlands, which can be harvestable, namely those mowed formerly in traditional haymaking. The practice of traditional haymaking is dying out in Sweden today but there are several good reasons why it should to be reconsidered. Nature- and cultural values are obvious, also the unutilized energy in the grass.The suitable types of wetland that were specifically studied were the productive wetlands; meadow marshes and wet meadows. These wetlands are represented in the Swedish meadow- and pasture inventory database; (TUVA) and the Swedish national wetland inventory (VMI).
