Underso?kning av tryckfall relaterat till avstånd mellan två 90 graders kro?kar i cirkula?r ventilationskanal

Due to higher standards of living around the world, greater industries and larger infrastructures causes an increase of the global energy consumption. This harvest of energy puts a great stress on the global environment. With this development, it becomes increasingly important to utilize energy resources in the best possible way.Fans are components that are often used in the industry and in households. A common problem is that the fan is oversized. An oversized fan causes an excessive flow, which has to be adjusted in order to achieve the correct flow.

Produktionsskillnader och virkesskador med olika typer av matarvalsar :

Earlier investigations showed that damages on timber from feeding rolls could be within the lower classes of damage according to VMRs classes. Knowledge about differences in productivity between kind types and aggressive types of feeding rolls is necessary because it should influence the question about damages on timber caused by different feeding rolls. In this study the production and timber damage in a harvesting head were evaluated at three levels of pressure (8, 10 and 14 MPa) on the feeding rolls, and with three different types of rolls. One type, the rubber cushioned steel plate roller had 10 mm studs and rubber damping, one ?middle? type made of solid steel with 14 mm studs, and one aggressive type, also made of solid steel with 18 mm studs.

Noteringsplatsskiftets betydelse för ett företags värde

Studien visar att en positiv onormal avkastning uppstår i och med att kungörelsen av ett noteringsplatsskifte offentliggörs. Den positiva onormala avkastningen återgår från och med det fysiska skiftet till OMX från de mindre noteringsplatserna. En temporär värdeutveckling som stöds av Price pressure hypotesen och som förklaras av handelsvolymförändringar i aktien..

Behandling av bensår ur ett omvårdnadsperspektiv

Swedish studies have shown that more people than expected have problems with leg ulcers and that the yearly cost for treatment per patient is approximately 26 500kr. Since the elderly population is on the rise, there is a need to highlight this growing problem, to make sure that proper assessment tools are used and to improve the standard of care given to patients with leg ulcers. The aim was to show what a difference the nurse can make to patients with leg ulcers. With all types of wounds it is imperative to establish if there is any underlying reasons since certain illnesses can cause more wounds or delay the healing process. The doctor is responsible for making the diagnosis and to prescribe the correct treatment whereas the nurse?s responsibility is for the nursing care and its documentation.

Patienters upplevelser av att leva med venösa bensår utifrån ett fysiskt, psykiskt och socialt perspektiv - En litteraturstudie

The purpose of this study was to describe patients? experiences when living with a venous leg ulcer in physical, psychological and social perspectives. The articles used to describe this condition were found in the databases: PubMed and Cinahl. Ten articles were included in the result: five with a qualitative approach, two with a quantitative approach and three with both qualitative and quantitative approaches. The results were presented through three headings: physical, psychological and social.

Tidspress och ekonomiskt risktagande

Stress and time pressure is more present in todays labor markets. In financial markets a securities broker is forced to take decisions on investments under high cognitive load and under extreme time pressure. The research of decision under risk gained new ground with the development of the prospect theory and gave us new insights to the decision making of men. Prospect theory has shown that people are risk seekers when dealing with loss decisions and risk avert when dealing with profit decisions. The value function are defined over gains and losses.

Blodtrycksfall, pulstryck och lindriga kognitiva symptom - En polytom logistisk regressionsanalys

People live longer. There is a growing need to increase the knowledge of aging and of the need among the elderly for medical care in the near future. As a step towards meeting this need, a survey among the elderly in Skåne is made by the division of Geriatric Medicine in Malmö University Hospital. This survey is called Gott åldrande i Skåne, GÅS. A frequent decease among the elderly is Mild Cognitive Impairment (MCI).

Krafter på rörsystem vid transient flöde : En jämförelse mellan RELAP5 och Fluent

At Forsmarks Kraftgrupp AB (FKA) forces on pipe systems due to transient flow are frequently calculated as a step to verify their structural integrity. In nuclear industries these forces are often calculated with a one dimensional thermal-hydraulic analysis-code called RELAP5. When calculations regarding more complex geometries are needed, the three dimensional code Fluent is often used. This code is highly time consuming and requires large computational power.This projects aim is to compare calculations of pressure, flow and forces carried out by RELAP5 and Fluent for an arbitrary pipe section during transient flow conditions. This has been accomplished by constructing a simple geometry for which a transient flow is simulated in both programs.

Riskfaktorer för trycksår vid planerade neurokirurgisk operation som varar längre än fyra timmar

Bakgrund: Abort har förekommit i alla tider och idag utförs abort lagligt på mångaställen i världen. Abort innebär att avsluta en graviditet och i norden ökar antaletaborter, trots tillgång till preventivmedel. Anledningen till att kvinnor väljer attgenomföra en abort kan vara många och huvudorsaken är en dålig eller ingen relationmed fadern. Att besluta sig att genomgå en abort är för många inte enkelt och där blirsjuksköterskans stödjande omvårdnad viktig. Därför är det av stor vikt att ta redasjuksköterskornas upplevelser av omvårdnaden i abort situationer.

Nya kriser, gamla källor : en kvantitativ studie om nyhetskällor på expressen.se och dn.se under katastrofen i Japan

In a press release from the Swedish church it says that the pressure from people who are in need is increasing on the deacons in Sweden and that it?s getting higher each year. This study contains the search of knowledge about the deacons of the Swedish church, if they actually feel an increasing pressure and in what way, how they are handling the possible pressure from people in need, if that pressure is too high and if the deacons feel that they can assist the people seeking their help. The study also aim to provide more knowledge about the deacons experiences of the opportunities and boundaries (or obstacles) they meet in their line of work and how they handle the boundaries when/if they can?t provide the help that the people need.

Distriktssköterskors upplevelser av att kunna främja hälsa hos patienter med venösa bensår - En kvalitativ intervjustudie

I Sverige lider ca 50 000 människor av svårläkta bensår och av dessa är ca 50 procent or-sakade av venös insufficiens. Patienter med bensår upplever ofta att de påverkas negativt fysiskt, psykiskt och socialt. Syftet med studien var att beskriva distriktssköterskors upple-velser av att kunna främja hälsa hos patienter med venösa bensår. Metoden som valdes var kvalitativ innehållsanalys med induktiv ansats. Data samlades in genom intervjuer med nio distriktssköterskor.

Preventivt omvårdnadsarbete inom riskområdet trycksår : En registerstudie utifrån kvalitetsregistret Senior Alert

Trycksår orsakar lidande för patienter och höga kostnader för sjukvården. För att förhindra uppkomst av trycksår är det viktigt att identifiera patienter med ökad risk för trycksår samt att aktivt arbeta med preventiva omvårdnadsåtgärder. Ett strukturerat arbetssätt kan göras utifrån kvalitetsregistret Senior Alerts rekommendationer. Senior Alert är inriktat på förebyggande vård av äldre över 65 år och i registret registreras bland annat risk för trycksår, planerade åtgärder samt sjuksköterskans utvärdering av de insatta åtgärderna. Syftet med studien var att kartlägga täckningsgrad, utförda riskbedömningar och planerade åtgärder avseende risk för trycksår i kvalitetsregistret Senior Alert.

Processdatorsystem för tryckreglering

The task of this project was to build an computer processing system for pressureregulation, in which the pressure loss over the open hydrolicvalve should be kept as low as possible. By using an cross connected proportional directional valve the valve problem could be solved. The control- and regulationproblem for the pressureregulation system was solved by using the DAQ- card NI6035E from National Instruments and the computerprogram Automatic Pressure Control 1.0 which has been software developed and written in Visual Basic. The final result showed that correct processvarible was obtained in 0,5 seconds, when the setpoint was changed in the testarea 0 - 2,5 MPa..
