BackgroundResearch shows that the majority of patients feel anxiety before and during anesthesia. It has been shown in several studies that preoperative anxiety may cause adverse effects in the postoperative course. Nurse anesthetists have a key role in creating a safe environment and the opportunity to use different interventions to reduce the degree of anxiety.AimThe aim of the study was to examine which interventions may reduce anxiety in adult patients before and during both general, local and regional anesthesia.DesignSystematic literature review with a quantitative approach.ResultsSeveral studies indicate that gabapentin and pregabalin can reduce anxiety before and during anesthesia. The anxiety reducing effect appeared to be dose dependent. The naturopathic drugs Citrus aurantium blossom and Passiflora incarnata Linneaus were found to reduce anxiety before anesthesia.
Evolutionär algoritm för schemaläggning av kontinuerligt skiftarbete : Schemaläggning med ergonomiska riktlinjer
Många organisationer har ett behov av bemanning hela dygnet alla dagar i veckan. Personal vid sådana organisationer organiseras i arbetslag som enligt ett arbetsschema löser av varandra under dygnets gång. Beroende på hur dessa arbetsscheman utformas kan de få en negativ inverkan på personalens hälsa. Den här rapporten handlar om utvecklandet av en algoritm som genererar arbetsscheman med ergonomiska riktlinjer, det vill säga arbetsscheman som utformats på ett sådant sätt att negativa effekter på personalens hälsa undviks. Algoritmen som utvecklas baseras på optimeringsalgoritmen Squeaky Wheel Optimization.

Utvärdering av ett större bergvärmesystem i en flerbostadsfastighet som har konverterats från fjärrvärme
This master thesis is an in-depth study of an existing heating system at a household cooperative in Uppsala that has been converted from district heating to a bedrock heat pump system. The study focuses on an economical system optimisation of the building?s complete heating system. The aim was to determine how well a heat pump system in large buildings actually work, find out possible ways to optimize the existing system and point out important system parameters for new heat pump installations in larger buildings.The project points out a possible energy cost reduction of 45 % without investment and further cost reductions with equipment investments. A reduction by 30 % is possible by improvements in the regulation system and 15 % is possible by maintaining the brine system.
Flytande sågklassläggning på Iggesunds sågverk
Syftet med denna studie är att beräkna de ekonomiska konsekvenserna för Iggesunds sågverk att övergå från diameterbaserad sågklassläggning, som används i dagsläget, till flytande sågklassläggning för delar av sågverkets timmerkurva. Huvudfrågeställningen indelades i olika delfrågor som undersökte hur volym- och värdeutbytet, planerbarheten och produktiviteten påverkades. Studien grundar sig på teorier om den ekonomiska konsekvensen av ett beslut där resonemang om alternativkostnaden ingår, volym- och värdeutbyte av råvaran samt teorier om produktion, produktivitet och planerbarhet.
Studiens resultat kommer att användas av Iggesunds sågverk i ett fortsatt utredningsarbete om effekterna av flytande sågklassläggning på hela timmerkurvan. Till detta utredningsarbete har en metodik utformats och ett rekommenderat arbetssätt presenteras i kapitel 7.
Utvärdering av BeWi Byggsystem
The construction industries are relatively conservative type of business that takes a longtime to adjust for new methods and embrace new ideas. It dose not matter if the newmethod seems to be an improved method as long as it is new and untried. Constructioncompanies are reluctant to change form a longtime working method to a relativelyunknown method.The purpose with our report is to perform an evaluation of BeWi construction method.Our goal are to present the generally opinion about BeWi from the contractors that hasbeen in contact/worked with the method. We also want to know from the contractor?spoint of view if BeWi and the method measure up to the standards that are presented byBeWi and if they believe that improvements need to be done.Our progress up to the final report has consisted of three parts[1]Field studies[2]Interviews[3]Literary studiesWe started out with field studies where we took notes and observed all the includedworking phases on the construction site when using the BeWi method.
Lokal logistikoptimering för ENA Energi i Enköping
The cost for forestry logistics in Sweden is about 25 percent of the total cost of getting the raw material to industry (Anon., 2010). There might be much to gain by taking a look at your supply chains on the logistic side in your company. In this report the logistic chains by Mellanskog for ENA Energi AB in Enköping has been looked in to. ENA Energis plant is a combined power and heating plant and about 99, 5 percent of their fuel consisted of bio energy in year 2009 (ENA Energi, 2011, länk A).
The main purpose with this report is to look at three questions:
1. How does the supply chain look today? From forest to industry.
2.
Konstruktion av en autonom vindstation
Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.
Interaktionsloggning i Scania Interactor
Scania provides a fleet management system for hauliers who want to control their fleets in anefficient way. The system includes an onboard computer with touch screen called ScaniaInteractor where the driver can access GPS navigation, order support, message service and otherfunctionalities. The purpose of this thesis is to develop a concept for logging the user interactionon the Interactor and analyze the result which enables further development and optimization ofthe interface.A demonstration application is designed, implemented and tested for the purpose of showing thepossibilities and difficulties with logging of interaction. The result shows that logging is quiteeasy to implement and that the amount of produced data is small and therefore not expensive totransfer via GPRS to a central server where searching and analysis can be done. On the otherhand, the biggest challenge lies in the analysis and interpretation of the logged data and to applyit to the development of the interface.

Förgiftningar hos hund och katt
Cats and dogs are often unattended by their owners both indoors and outdoors, and therefore there is always a risk that they will get hurt. In the past, poisoning cases was considered unusual, but nowadays they are considered more common. As a veterinary nurse, it is important to know the common symptoms of poisoning, especially when working with emergency veterinary care. A very essential part of the profession as a veterinary nurse is to inform pet owners about the potentially dangerous substances and how poisonings can be prevented.
The purpose of this report was to find out what is written scientifically about some common poisonings in dogs and cats and to present available statistics that covers the number of animals poisoned by various substances in Sweden. Hopefully this essay can also be used as a handbook for professionals in animal health care and to assist in educating pet owners.
The report mainly covers groceries found in many homes, often easy accessible.

Automatiserad konstruktion av analoga förstärkare
The last few decades the development in the field of electronics has been huge. The components performance gets better at the same time as the manufacturing cost decreases. Many of the design moments that have to be done, are done automatically today, but it can get better. Especially for analog circuit design.At Electronic System in Linköpings universitet, research is in progress to develop a tool that can design analog circuits in reasonable time. It means that it has to size the components (transistors, resistances, capacitances etc), so that the circuit can fulfill the performance requirements.
