Produktutveckling av mobil förstahjälpenstation

This thesis is about a part of the marquetrytechnique, scorching. Scorching is made by heating up something, put a veneer into the heated substance and make a controlled burning. This technique is old but still used today and have according to me great potential for development. In my work I wanted to give the scorching greater room then I earlier have seen. I wanted the scorching to be the dominant ingredient for a decorative element in a piece of furniture or an interior.

Vad avgör om en patient skrivs ut tidigt eller sent vid dagkirurgi med intravenös anestesi som sövningsmetod

Dagkirurgi verksamheten ökar och det pågår en debatt om vilken anestesiform som är mest lämpad för denna verksamhet. Snabb återhämtning, god kvalitet, kostnadseffektivitet och få biverkningar är målen för att få patienten att kunna gå hem samma dag. En kvantitativ studie med en enkät framkonstruerad för studiens syfte utfördes. Syftet med studien var att undersöka vad om avgör om en patient skrivs ut tidigt eller sent vid dagkirurgi med övningsmetod intravenös anestesi Target Controlled Infusion TCI eller Total Intraveös Anestesi TIVA. 20 stycken patienter på en dagkirurgisk avdelning observerades postoperativt av ansvarig sjuksköterska, som fyllde i frågorna i enkäten.

Upphängningssystem

Examensarbetet som utförts på Institutionen för Maskinteknik vid Blekinge Tekniska Högskola i samarbete med Kockums AB har benämningen ? Upphängningssystem?. Dagens upphängning av rör, ventilationsrör och kabelbanor består av ett antal olika singelupphängningar utan större samordning. Detta har gjort att Kockums AB önskat få fram ett samordnat upphängningssystem som klarar av alla dessa upphängningstyper. Utifrån denna problemställning har vi arbetat oss fram till ett upphängningssystem bestående av ett multisystem och ett flertal singelupphängningar för rör, kabelbanor och ventilation.

Åtgärdsförslag och känslighetsanalys vid energieffektivisering ur ett fuktsäkert perspektiv : En fallstudie på timmerhuset Sofiedals herrgård

This thesis investigated the possibilities to resume cultivation of an old manor house built of timber and what this would mean from an energy and moisture perspective. The building in this case study is named Sofiedals mansion and was built in 1858 in Valbo 11 kilometers west of Gävle.The structure of the house was documented and used as a starting-point for carrying out calculations focused on energy and moisture aspects. With the help of a number of computer programs and a conducted air tightness test, the buildings energy consumption were calculated and compared with the current building regulations.In addition, the building was analyzed considering energy retrofitting and what it meant for moisture problems. The energy retrofitting consisted of additional insulation, decreasing the buildings permeability through air sealing; window and door replacements. When a building is equipped with natural ventilation it is difficult to know its precise performance and how an energy retrofitting affects it.

INOMHUSMILJÖ I SMÅHUSMED FTX-VENTILATION : EN LITTERATURSTUDIE MED ENKÄTUNDERSÖKNINGAR OCHMÄTNINGAR

This master thesis was initiated with the aim to answer at what level of installed capacity of wind power in the northern parts of Sweden it would be beneficial to improve the transmission capacity from the northern Sweden. During the process of this work the aim has changed to try and create a model that can be used to analyze how well the hydro power installed in the northern Sweden can even out the quick changes in wind power production.To create a good model of all hydro power in northern Sweden is a very large job, unfortunately too large for a master thesis. This report therefore ends with an extensive analysis of the simplifications that have been made and their effects as well as a list of the future work that has to be done.The model that has been created have shown to be effective and produce good results. The conclusions that can be made is that the northern Swedish hydro power have very good possibilities to balance the wind power production. Only a few cases where water have been spilled even though there has been some free capacity has been discovered.

Ämnesordstilldelning ? en praktik i förändring. En jämförelse mellan författares och indexerares ämnesordstilldelning.

The aim of this paper is to compare subject headings by the authors of the work and those administrated by professional indexers. The empirical setting for the study lies within the sociological discipline. The questions asked are:? What overall similarities and differences between subject headings administrated by authors versus indexers can we find?? What qualitative advantages and disadvantages can we establish between subject headings generated by natural language versus controlled vocabularies?Subject headings in the Swedish national library catalogue Libris and in five Swedish universities platforms for academic publishing are studied and compared. Today it is praxis at Swedish universities that administration of subject headings is done by authors and not by professional indexers.

Energikartläggning av polishuset i Gävle : Åtgärdsförslag för ett minskat energibehov i fastigheten Gävle Söder 17:10

The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.

Hur personer med smärta av WAD upplever vardagen.

The aim of this study was to describe how persons with Whiplash associated disorder experience how the pain affects them in their daily life. The design of the study was descriptive with qualitative, individual interviews, questionnaire with background facts of the examination group, and diary notes from persons with pain of WAD. Method for selection was convenience. Through contact with the association of whiplash group in a county in middle of Sweden, the majority of the examination group for the study was found. Five persons where given information about the study, one of them choose not to take part of the study, and one of the persons did not complete the study.

En studie av fysiska, organisatoriska och individuella riskfaktorer hos arbetstagare med datorarbete

Musculoskeletal disorders (MSD) are common in individuals with computer based work. Thecurrently known risk factors for these disorders is in the literature derived to physical,organizational and individual factors. A recent survey of three working groups at a companyin Stockholm explored that more than 50% of the employees had neck and shoulder problems.Aim: The study aims to create a better understanding for the current musculoskeletalproblems at the company. Such an understanding is created by examining the physical,organizational and individual risk factors in the workplace and the result can provide a goodbasis for intervention proposals.Method: In order to answer the aim of the study the authors chosed to use both qualitativeand quantitative methods of data collection through interviews and questionnaire survey. Theinterview and questionnaire was designed to create both a specific and comprehensive pictureof the physical, organizational and individual risk factors having a bearing effect on theexisting MSD problem.Result: Seven categories were compiled from interviews, which largely deals with the factthat high demands can lead to behaviors that may pose a significant risk for the occurrence ofMSD.

Bergkyla och bergvärmeutredning för industrilokalen Rödbergsmyran 5 i Umeå, Västerbotten.

Grubbe Ventilation AB is a sheet metal and ventilation company who provides design, installation, service, and repair of ventilation. The company is expanding their business by building a new facility in Umeå, Västerbotten. The property is designed to be used for both office and industrial work.Grubbe Ventelation AB has not yet decided upon wish system which is to be established to provide the building with heating and cooling. The consulting firm Umeå Projekt Team has therefore been asked to investigate the possibilities to invest in geothermal- heating and cooling.If the investigation of a geothermal heating- and cooling system would provide favorable results it would be a very appropriate alternative that provides energy at low costs and are an environmentally friendly option as the energy comes from stored solar energy in the ground is provided by stored solar energy in the ground.The facility ´s heating and cooling consumptions are calculated in the program BV2 and the result indicate a heating demand of 185 000 kWh per year due to thermal transmittance, transmission losses, heating of warm water and a cooling requirement of 5500 kWh.Three different systems of geothermal heating and cooling were tested in the computer program Energy Earth Design. The results show no difference in the dimensioning of the drill hole if merely heating were to be used or both heating and cooling were to be established.

Implementering av Patientsimulator för Anestesimaskiner

In order to facilitate testing of anesthesia machines a patient simulator has been required by Maquet Critical Care AB. A patient simulator has been developed to reduce expensive and time consuming animal experiments and temporary lab arrangements. The patient simulator has been developed and designed to simulate human lungs with regards to anesthetic uptake, production of carbon dioxide and heating and moisturizing exhaled air.The system comprises a container and a test lung to simulate the volume and the dynamic of the human lung. The simulation of uptake of anesthetics has been implemented by pumping a fraction of the gas from the container through a bypass circuit with an active charcoal filter that adsorbs volatile anesthetics. The flow through the bypass circuit is generated by a pump and is controlled by a linear valve.The resulting performance of the patient simulator has fulfilled the requirements.

Kontrollerat och okontrollerat språk En litteraturstudie i informationsåtervinning i databaser.

This thesis deals with one of the main questions within information science: The question about controlled and uncontrolled vocabulary and which of the two that are most effective when it comes to retrieve relevant information from electronic databases. The method used here is literature studies. I have described and examined five empirical studies which has been done in purpose to compare the effectiveness in retrieval with controlled and uncontrolled vocabulary, in the way they are used in retrieval of information in databases. The studies I have examined have also used recall and precision as a value to measure the effectiveness of retrieval. The studies which I have chosen is also limited to deal only with studies that have been done in bibliographic databases.

Att söva den feta patienten- med fokus på ventilationen

Fetma och övervikt är ett hälsoproblem som drabbar mer än var tionde person och antalet individer med BMI >30 ökar ständigt. Som en följd av detta kommer allt fler patienter som genomgår anestesi att ha ett högt BMI. Förändringar i respiration, luftvägsanatomi och ett flertal andra fysiologiska förändringar i kroppen gör generell anestesi för patienter med fetma till en anestesiologisk utmaning. Syftet var att beskriva vilka omvårdnadsåtgärder anestesisjuksköterskan kan använda för att bibehålla god ventilation hos feta patienter vid generell anestesi. Studien genomfördes som en litteraturstudie där 12 vetenskapliga artiklar analyserades.

Energianvändning i restauranger i Umeå kommun

Efficient energy use in restaurantsUmeå Municipality wishes to combine energy issues with food control, and thus help restaurants to become more energy efficient. During March and April 2010, I visited seven restaurants and interviewed restaurant personnel about current state and application of kitchen appliances, using a checklist to make sure that the same questions were asked at all restaurants. The restaurants were all different sizes and offered different kinds of food. The study mostly focuses on energy efficiency by behaviour and not on location or technology. Almost every restaurant that was visited had the potential to improve in one or more areas, such as kitchen appliances, lamps and lighting fixtures, heating, cooling and ventilation.

Akta er för dörrarna - en observationsstudie av dörröppningar i en hybridsal

SUMMARYPrevious research has shown that there is a connection between the doorways and postoperative wound infections. Despite recommendations from Socialstyrelsen and the individual hospitals' PM there is still high traffic in the operating theatres. In a hybrid theatre environment combined X-ray techniques of surgery, resulting in it being further two categories inside the operating theatre. This may generate an increase in traffic flow. The study is a prospective, non-participant observation study conducted in the spring of 2013 at a university hospital in western Sweden.
