Delirium är ett vanligt tillstånd på intensivvårdsavdelningen (IVA) och forskning visar attpatienter som drabbas av delirium har högre mortalitet, längre vårdtider på sjukhus och sänktlivskvalitet lång tid efter vårdtiden. Det finns olika former av delirium: hyperaktivt,hypoaktivt och blandformer. Den vanligaste formen, hypoaktivt delirium, är lätt att feltolkasom översedering eller depression. Att använda sig av bedömningsinstrument kan göra attdelirium upptäcks tidigare och att patienten snabbare får adekvat vård, vilket kan lindraförloppet. Det har utvecklats olika instrument för att bedöma om patienterna har delirium.Syftet med denna studie var att undersöka om användandet av CAM-ICU (ConfusionAssessment Method for Intensive Care Unit - ett bedömningsinstrument av delirium) är ettanvändbart mätinstrument för sjuksköterskan att upptäcka delirium hos patienter som vårdaspå IVA.

The actual project presents the development of a testing rig for a steam engine. A short overviewabout the development of steam engines is presented, until arriving to the development of thepresent engine, which will require to be tested in different ways.The testing rig studied on this project (based on a Lanchester engine) will be used to testdifferent materials and layouts for the group Piston-Cylinder.The engine is a high performance steam power engine, which is going to have a highpower/dimensions ratio, what will lead to require high performance components and materials.An introduction to the testing rig is presented, and the entire design project is done in order toreplace the disappeared documentation of the current testing rig, built on the 1970?s. Also somemodifications done in the original testing rig are presented, as well as some detected problemsand their possible solutions..

Så länge som människor strövat omkring på jorden har det bytts och handlats med varor och tjänster. Det är i människans natur att göra affärer.Logistik och inköp har därför naturligt blivit stycken i den mänskliga handelshistorien, samhället men främst företag påverkas och påverkar denna nutidshistorias utveckling. Då konkurrens har blivit ett stort inslag för att lyckas i ett företag så har företag försökt hitta nya metoder för att hävda sig på den globaliseringen marknaden. De verktygen kan skilja sig från företag till företag beroende av vilka lösningar företag vill lösa men exempel på det kan vara Supply Chain Management som kommer att behandlas i denna uppsats. De andra teorier som kommer beröras är fusion, Just-in-Time och inköp.

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

Introduction: The complexity of the neonates? way of expressing pain is a difficulttask for the pediatric nurse. The Swedish national guidelines for prevention and treatmentof pain in the newborn infant is suggesting that departments regularly use structuredmethods, such as pain assessment instrument, for the assessment of pain in the neonatalperiod. Previous research shows that pain assessment instruments are only used in abouthalf of all pain assessments in Sweden. Neonate's cannot verbally communicate their pain,and are therefore dependent on the pediatric nurse to acknowledge the pain.

The competition for Norway spruce pulp wood in Central Sweden increases, forcing the supply-structure of Holmen to face two important challenges. Firstly, it is of the outmost strategically importance to secure the long-term supply of Norway spruce pulp wood to the industries. Secondly, Holmen desires to increase the obtainable volume of Norway spruce pulp wood. This would enable the company to choose volumes in the lower price-segments and thereby decrease the dependency of costly marginal volumes. As this work shows, one part in managing these challenges could be to lower the quality standards concerning root rot (Heterobasidium annosum). Facts presented in the work shows that: 1. Technically, the TMP-industry of Braviken can handle a much more rotted pulp wood than that used today, although the cost of refinement increases.

Vårt moderna samhälle är idag beroende av dagliga transporter som både är en stor kostnad för producerande företag och dessutom har en stor miljöpåverkan. Främst eftersom klimatfrågan idag debatteras flitigt men också för att det finns stora incitament för företagen att minska sina transportkostnader kommer vi, med största sannolikhet att se stora effektiviseringar av denna bransch inom en snar framtid. I detta arbete behandlas därför i vilken utsträckning två välkända teorier, Lean och Supply Chain Management, kan användas för att optimera transporterna främst vad gäller kostnad och miljöpåverkan. Efter att ha analyserat ett flertal rapporter som behandlat dagens transporter, transporttyper av olika slag och pågående miljöregleringar samt intervjuer med två svenska industribolag har vi kommit fram till att dessa två teorier inte lämpar sig i alla situationer. Lönsamheten i användandet av dessa två teorier beror på vilken teknisk grad företagets produkter har samt hur stor företagens produktion är.

The purpose of this thesis is to investigate the possibilities for shore side electricity in the ports of Västerås and Köping. A technical solution to connect the vessels to the local grid is suggested and the investigation is also aiming at an understanding of how the environment is affected by the use of shore side electricity. Furthermore, the costs of shore side electricity are considered.The maximum power demand of a vessel visiting the ports today is relatively small, but the ships visiting the ports in the future might have a larger power demand. The suggested dimension for the system is 5 MW and the result shows that the shore side electricity requires the power distribution to the ports to be expanded. The most useful solution in the ports is to connect the ships with 12 kV from a connection box in a pit at the quay.The investigation of the costs shows that it is cheaper for the ships to use electricity compared to the marine fuel.

By doing a qualitative study using focus-group-interviews in three municipalities, we were able to examine the personnel?s experience of cooperation issues and opportunities in BoDa-units.

The viscosity of air buildings is a hot topic within the construction performers, which the industry feel they have too little knowledge about. This study is mainly aimed against air density in apartment buildings and airflow measurement. The study consists of a theoretical reference, educational visit, interviews and a survey conducted among construction workers at Magistratshagen in Linkoping.Earlier requirement in terms of air leakage through the climate screen was removed and today there are only energy requirement for a dwelling in Boverkets Building Regulations. The difference between a passive and a typical air tight construction is that the passive house have a maximum requirement of 0.3 l /s m2 of air leakage through the building climate screen. The requirement imposed on passive houses is to minimize the supply of power and energy for heating the building.Air tight constructions have heavy demands on the performance and accuracy of everyone involved with the project. The client must specify their requirements and also be prepared to pay for any additional costs. The architect and building planners have to design the building with regard to air tightness. Finally, the construction workers are required to do a careful work in order to get all the connections in the building air tight.The study suggests that an air tight building is a closed system where no forced ventilation exists. There are no reasons not to build too tight as long as there is a functioning ventilation. In this study the authors ask themselves how an air tight building changes over time. No theoretical information has been found on these changes, but the respondents assume that air density decreases with time. The deterioration is mainly assumed to be caused by construction materials changes over time. The study shows that construction workers knowledge of air tight construction is mixed, which they themselves admit in the survey..

The purpose of this thesis has been to determine experimentally how good a peltierelement is to convert waste heat from wood burning. Three different peltier elementswere used in a comparison study. The comparison was mainly done to know howmuch power could be obtained from each element. Even, a circuit with a step-upfunction has been created to give a higher output voltage than the peltier elementitself. The result of the experiments was a low output power, the highest valuereached 2.18W.

Bakgrund: Det senaste decenniet har allt fler stormarknader och lågprisbutiker öppnat vilket har lett till att de mindre livsmedelsbutikerna blivit utsatta för större konkurrens. Parallellt med att stormarknaderna tagit marknadsandelar i dagligvarubranschen har även större fokus riktats mot ökat samarbete och informationsdelning i försörjningskedjan, så kallat Supply Chain Management (SCM). Inom dagligvarubranschen har Efficient Consumer Response (ECR) utvecklas ur samma idéer som SCM men med fokus på livsmedel och dess försörjningskedjor. I grund och botten handlar ECR om företagens gemensamma arbete för att integrera verksamheter, minska kostnader samt producera största möjliga nytta för slutkonsumenten. Med tanke på den ökade konkurrensen i dagligvaruhandeln samt det faktum att det finns ont om tidigare forskning om små och medelstora företag (SME:s) relaterat till SCM/ECR, är det intressant att undersöka hur dessa företag påverkas av samarbetet.

AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power.  ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant.  As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol.  Etanolens framtid vilar på bra lösningar för framställning.  I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle.  Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.
