Utveckling av en metod och en utrustning för mätning av bränslesprayers rörelsemängd

A new type of device for measuring thev m& ?rate of fuel sprays from a diesel fuel injector has been developed and the various steps in the development are described. The device works by deflecting all of the sprays from the injector at the same time by using a bell shaped deflector. A load cell consisting of a machined steel part with strain gauges mounted on it measures the resulting force. The shape of the curvature in the deflector bell shape has been evaluated by photographing the flow in a 2D?version of the curve shape.

Turbinkretspump system - Kraftvärmeverket i Borås

The Rya power plant in Borås produces district heating, district cooling and electricity. The plant is owned by Borås Energi och Miljö AB and is run by Dalkia Facility Management AB.In order to get the best heat exchange from the district hot water a pair of twin pumps and a turbine circuit pump are used as return pumps. Turbine circuit pumps are used to increase the pressure through the heat exchangers at the power plant. The pumps are in use when the flow is over 2 000 m3 h-1 and during the summer when re-cooling is used to improve the effectivens of the heat boilers.Since the pumps, that are parallel connected, rotating at a fixed rate per minute, the pressure is regulated with regulating valves. This report shows that during the 4,300 hours that the pumps where in use, energy corresponding to 590 MWh was wasted.

Meeting, greeting & seating : a design proposal for Magomeni garden, Dar es Salaam, Tanzania

More than fifty percent of the world population today lives in cities, and the pressures of urbanisation are particularly present in developing countries. As landscape architects, it is important to gain knowledge about the effect of urbanisation and ways to prevent the negativities. Experiencing the effects in person in a developing country, as well as learning from and about other cultures, enhances the understanding for global situations. Dar es Salaam is located in one of the most rapidly urbanising regions in the world, which puts pressure on the environment and the humans living in it. Lack of means to regulate land development has led to a situation where expansion of unplanned settlements occurs, with spatial disorder as a consequence. This has in the extension led to a decreasing amount of publicly available and qualitative green spaces, and degradation of the few ones that exist. There are facts that strengthen the status of urban parks, which especially becomes relevant in developing countries where many people live in sparse and exposed conditions.

Naturliga filtermaterial för reduktion av metaller i dagvatten

Förorenat dagvatten från Stena Gotthards metallåtervinningsanläggning i Eskilstuna har filtrerats genom kolonner innehållande två olika adsorbenter, torv och furubarksflis. Torv är en organisk jordart som främst används som bränsle och furubarksflis är en biprodukt från skogsindustrin. Båda filtermaterialen är relativt billiga och finns i stora kvantiteter i Sverige. Filtermaterialen har visat sig ha varierande kapacitet att adsorbera metaller i vatten på grund av själva materialet samt vattnets sammansättning. Resultatet från den här studien visar att av de två undersökta filtermaterialen så har furubarksflis störst kapacitet att reducera bly, koppar och zink från det specifika dag vattnet..

PCB i byggnader : Handlingsplan för saneringsarbetet i Eskilstuna kommun

Polychlorinated biphenyls, PCBs, were used in elastic sealants in buildings during the years1956-1973. Studies of PCB have revealed that it is harmful for humans and animals,especially water-living predators and other top-predators. It is also a persistent organicpollutant and remains in the environment for a very long time. To reduce the levels of PCB inthe environment, it has to be removed from the buildings. According to Swedish law, theproperty holder has to decontaminate sealants with a PCB level of 500 mg/kg or above.

Komplikationer vid behandling med cochleaimplantat

Cochlear implant has become a common treatment for people with severe hearing loss. As the field of cochlear implants is developing rapidly a larger group of patients will be implanted. Therefore, it can be of interest to identify which complications are most frequently occurring. Objective: The aim of this study is to identify and present the most common complications in cochlear implant treatment and to identify surgical issues that have to be addressed during implantation. Method: A review of retrospective case studies regarding complications has been made.

Undervegetation : användning av vedartade marktäckare i anläggning

The use of the robust and durable woody ground covers is increasing, not in the least in public places. The group includes low shrubs of different height that effectively build low, tight vegetation that covers the ground. Despite all the good qualities the knowledge about them is quite low and there are ideas about them of being dull. The woody ground covers manage to struggle against weeds effectively by competing for nourishment and water, but above all, by the canopy of the ground covers that prevent the weeds from getting enough light. In that way the woody groundcovers can effectively compete with the annual weeds.

Lactobacillus reuteri som probiotisk terapi mot bakteriell vaginit hos avelsråttor :

?Jag tänker inte sitta hemma och sticka? ? En studie av sex nyblivna pensionärers informationsbehov och biblioteksvanor.

This study is about information needs and library habits among newly retired people. The purpose of this master thesis is to examine the affective and cognitive needs that come with retirement. In what way do the information needs of this group change due to retirement? In order to answer this question we make use of two theoretical models; Role theory and Wilson?s model of information needs. When it comes to library habits, we use Andersson and Skot-Hansens model to examine how newly retired people use the library now and how they could use it on basis of their needs in their new role.

"Vi är drabbade båda två" : En litteraturstudie om föräldrars upplevelse i samband med ett missfall

Bakgrund: Missfall är en vanlig komplikation i samband med en graviditet. Orsaken till missfall är flera och under ett pågående och hotande missfall finns ingen förhindrande behandling. Händelsen är ofta fysiskt odramatisk, men kan påverka föräldrarna emotionellt. Då det är kvinnan som blir fysiskt drabbad och därmed är patient, blir kvinnans partner i denna händelse ofta bortglömd. Både inom samhället och vården underprioriteras missfall och därmed kan upplevelsen hos föräldrar förbises. Syfte: Syftet med denna litteraturöversikt är att undersöka föräldrars upplevelse i samband med ett missfall.Metod: En litteraturöversikt som är baserad på tolv vetenskapliga artiklar.

Stress : En gransking av studenters stressnivå - Praktik och icke praktik

Practical and theoretical learning are methods that are used in schools as a way to prepare students for the working life. Within the practical learning knowledge is not only acquired to learn in practice, but the students must also be able to apply their theoretical knowledge to what he/she does. Against this background, the aim of the study was to investigate the importance of practical learning for students in college / university level and how they are experiencing the stress that may arise out of the loss of practical learning during their education, as well as their vision for working life after completing their education. The population of the study consisted of N = 36, which 18 of these had used both practical and theoretical learning and the remainder had only used theoretical learning. The method was a questionnaire survey with a high proportion of fixed alternative answers according to likert scales.
