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.
Leveranslogistik på byggarbetsplatsen
Problem: How do delivery logistics work in practice at the building site?
Where are the big problems? How to make building logistics more
effective? Do the site management and the haulers agree about
questions concerning both parties? What is possible to gain by
using better logistics? Is it possible to gain time with better
logistics and by that reducing the costs?
Purpose and aim: The purpose is to discover if there are any disagreements between
the site management and the haulers. If disagreements occur they
will be examined and probable measures based on the problems
will be suggested. Another intention is to bring key ratios
concerning time spent for deliveries forward. One aim is to update
a similar report made in 1972.
Biblioteket är till för användarna. En studie av folkbibliotekariers syn på bibliotekarieetik
The main purpose of this master thesis is to explore a selection of Swedish librarians view of professional ethics. The latest master thesis written on the subject was published in 1997, which concluded that the Swedish public librarians had a poor awareness concerning professional ethics. We wanted to investigate if something had changed. We interviewed six librarians from five public libraries, asking them questions concerning ethical guidelines, responsibility, censorship and selection, pressure from lobbyists, and ethical problems relating to Internet. The answers we got gave the impression of a divided profession, and the librarian?s awareness of professional ethics can hardly be said to have been improved since 1997.
MÄTNING AV LJUDIMMISSION FRÅN VINDKRAFT. VIDAREUTVECKLING AV METOD FÖR MÄTNING
The Swedish government have a goal that wind turbines shall produce 30 TWh by the year 2020, compared to about 3,5 TWh produced in Sweden during 2010. To minimize the disturbance that wind turbines create the Swedish Environmental Protection Agency has stated a guideline value that noise from wind turbines at nearby residents shouldn?t exceed 40 dBA, at 8 m/s wind speed. With advanced calculation models, like Nord 2000, the emitted sound from future wind turbines can be calculated at an early stage to optimize the power production without exceeding the 40 dBA. When the turbines have been built there is a need to verify that they really are within the guideline.
Byggnadsutformningens inverkan på energianalysen : En jämförande utvärdering av två energisimuleringsprogram
Since the demands from authorities regarding lower energy consumption havebecome increasingly strict, this puts new pressure on designers and builders, who notonly have to ensure an esthetically pleasing building, but also make sure it issufficiently efficient to pass under new laws and regulations.This thesis takes into consideration a wide range of various parameters and theireffect on a building?s energy consumption. For this evaluation a computer softwarecomparison between the two programs Autodesk Ecotect Analysis and AutodeskProject Vasari was performed.Autodesk Ecotect Analysis is better suited for studies made on individual factors whileAutodesk Project Vasari is better used in experiments regarding the geometricalshape of the stucture itself.The results from the two different software tools used, give us both differences andsimilarities. For instance, both software programs produced the same resultsregarding the importance of the windows of the buildings to ensure a highly energyefficient building, both when it comes to the windows size and their U-value..
Undersökning av titanföreningar för tillverkning av standarder vid användning av röntgenfluorescens
SECO Tools manufactures tool inserts for all types of metal cutting machining. (Ti,W)C is a common raw material used in the production. At arrival, the material (Ti,W)C is always analyzed. Titanium has previously been analysed with x-ray fluorescence spectrometry, but as the calibration has previously been performed with two different types of titanium (rutile and metallic titanium), the results has differed. Because of that, this thesis project has been devoted to analyze titanium, to find the best titanium compound for producing standards.The work has been performed using literature studies and many experiments in the laboratories at SECO Tools inFagersta,Sweden.
Blodtryck hos förskolebarn korrelerar med BMI redan från 12 månaders ålder
The purpose of this study was to describe how adolescents aged 12-18 years with inflammatory bowel disease experience their illness and what coping strategies they use to manage their illness and improve their wellbeing. The method used was a descriptive literature study, and the result of the study included 15 scientific articles. Our results showed that IBD affected the adolescent?s everyday life and social life with friends, family and activities. The adolescents also reported that they experienced a feeling of vulnerability, altered body image and that they saw themselves as different from healthy subjects.
Samrådsunderlag för Lysekilsprojektet : Forskning och utveckling av vågkraft
The aim of this research is to find out what environmental impact a wave power park has on the Swedish west coast by creating a consultation paper (?Samrådsunderlag?) for the Lysekilproject at Uppsala University. To highlight the complexity of the problem a system analytic approach was used and illustrated by a Causal Loop Diagram.The overall assessment of the Lysekilprojects wave power park at the Swedish west coast is that it will have a low impact on the environment. This is due to the relative small size of the wave power park and some technical solutions made with the environmental aspect in mind. Artificial reefs and a sanctuary for marine species are effects created by the wave power park and in the longer term the impact will give access to an untapped source of renewable energy, wave energy.
Hållbar avfallshantering : Ur ett ekonomiskt- och miljöperspektiv
Economy and environment has for a long time been studied separately and seen as incompatible. With a growing society and increasing pressure on environmental issues the need of a new economy with the environment included is necessary. This study examine if European Union´s picture of the waste hierarchy match the reality. Since the purpose with the waste hierarchy is to benefit environmental and economy. A survey was made over Käppalaförbundets waste from 2013, to see where the waste falls in the waste hierarchy.
Optimering av indunstningsprocess
The wastewater treatment plant at GE Healthcare's facility in Uppsala deployed a three step vacuum evaporator in 2007. The purpose of this was to pre-treat wastewater containing amines. The purpose of this thesis was to optimize thisprocess by reducing the amount of concentrate without releasing more nitrogen tothe environment and to examine if density could be used as a measurement of whenthe process should be ended.To create a foundation for optimization six test cycles were conducted with samples taken from all three steps. Both concentrate and condensate were tested as well as the incoming solution. Furthermore, the thesis has been expanded with a benchmarking part examining two different evaporators.
Utveckling eller avveckling? En intervjustudie av hur folkbibliotek hanterar besparingskrav
The purpose of this masters thesis is to examine how managers in public libraries are managing financial cuts. Questions posed are: What strategies are used by the library manager to handle the cuts and how are the strategies being worked out? What are the consequences of the cuts? How do the managers use their library plans in the work with the cuts and how do the plans change as a consequence of the cuts? Library managers in eleven communities are interviewed about their financial cuts in 2003 and/or 2004. The result shows that cuts are made in different ways. The study analysed the managers statements with a model about strategies created by Oulton.

Rättsenlighet och ansvarstagande i de ensamkommande flyktingbarnens asylprocess
Earlier this year the Swedish migration board gave a part of their responsibility for the separated children to those municipalities that have signed an agreement with them, so that the children can get the best handling of their matters and also to lift the heavy pressure of the Swedish migration board. Our aim in this paper is to see how this division is made and which areas of responsibility they have. We want to see how this process is being handled in relation to these children?s rights, the Convention on the Rights of the Child and the Swedish law. To get the best information possible we used a qualitative method.
Identified opportunities and challenges inCSR certification : the case of CSC9000T in China?s textile industry
Corporate Social Responsibility (CSR) issues have been received much attention in businessand management practises globally. Jensen & Yeh (2009, 3) state that ?The agenda ofCorporate Social Responsibility (CSR) has emerged as a factor in the process of globalization,and Chinese companies may sometimes feel pushed into this agenda without a clearunderstanding of the rationale behind it?. China?s textile and apparel industry, amanufacturing-based economy with its products bounding up with the consumers worldwide,has been facing enormous pressure to take CSR initiatives, particularly in relation toenvironmental issues and labor standards.
