Analys av designalternativ för snabbare dynamik i kolkraftverk med koldioxidavskiljning
Combustion of fossil fuels is today the dominating source of energy. During combustion,carbon dioxide is formed. The carbon dioxide accumulates in the atmosphere,which raises the global average temperature on earth through the so called greenhouseeffect. The only way to reduce the emissions of carbon dioxide from combustionin a coal fired power plant is through carbon capture and storage (CCS).Post-combustion capture is a technology to separate carbon dioxide from the uegas after the combustion for efficient transport and storage. The steady state operationof coal fired power plants with post combustion capture has already beenthoroughly investigated on a pilot scale, however much work remains to investigatethe plants dynamic operation.
Hur hanterar sjuksköterskor stress i arbetet? : En litteraturöversikt
Background: The nursing profession involves meetings and situations which can be stressful. The work environment can cause additional stress in the form of time pressure, lack of support from colleagues, management or disgruntled family members and patients. This places the nurse in a position that requires a sharpened ability to handle stress. It can become overwhelming and unmanageable and cause a serious threat to the nurse's health and wellbeing. To handle stress the nurses uses different coping strategies.Aim: The aim of the review was to gain a better understanding of how nurses deal with occupational stress.Method: A systematic literature overview study based on eleven articles, including both qualitative and quantitative studies.Results: Nurses deal with stress in different ways based on their own resources.
Design och konstruktion av laborationsutrustning till en kraftelektronikkurs
The purpose of this degree project was to build laboratory equipment for a new course in power electronics that starts this autumn 2010 at Uppsala University. The equipment is intended for student labs and it covers the most important areas of the course including rectifying, buck-/boost-converters and PWM-modulation. It is built as one sealed unit where all the electronics are built-in but visible and it has a connection board where students safely can connect the different circuits. The project has advanced from theoretical studies of circuit design, choosing of components and simulations to drawing the printed circuit board (PCB), soldering, case building, final testing and troubleshooting - basically most steps from an early idea to a final product. Measurements on the final product gave about the same results as the earlier simulations of the circuits and the result is overall satisfying..
"Klänningen som får en andra chans" : klädkonstruktion av återbruksmaterial
This report presents a bachelor thesis by Erika Gustrén aimed to increase people?s interest for recycling and reusing by create new products of things that already exist in most people?s homes in the materials textile, plastic and paper. That would be a modern and innovative way to contribute to a better environment.The goal with this project was to create three cocktail dresses made of the same pattern and design and with the three chosen materials. The project did not have its base at a company, therefore an external mentor was chosen to help and support during the development of the project. My mentor was Kerstin Boulogner who is a fashion designer and one of the members of GKF (Gotländska Konsthantverkare och Formgivare) in Visby.The project began with an analysis of the chosen materials; textile, plastic and paper.

Incidenthantering i molnmiljö
Incident response plans are faced with new challenges as organisations expands to the cloud, this thesis aims to highlight these challenges and their potential solutions. Our work has focused on managing the incident response in contrast to earlier work that has been focusing on preventing them.As with any development, security is seldom prioritized. Instead the focus are often aimed towards usability and functionality, which means incident response plans are written, implemented, forgotten and finally becomes obsolete. This could result in an organization losing their ability to produce acceptable forensic images, avoid severe downtime, or prevent similar incidents in the future, which are all important parts of incident response.Traditional incident response plans does not address incidents in the cloud. Thus, an absence of guidelines for managing incidents in the cloud becomes apparent.
Postoperativ återhämtning - en identifiering av bedömningsinstrument
Bakgrund: Postoperativ återhämtning har stor betydelse för en individs upplevelse av ett kirurgiskt ingrepp. Begreppet återhämtning är ett komplext begrepp och innebörden skiljer sig mellan patienterna och även mellan vårdpersonal. Vid bedömning av postoperativ återhämtning är det viktigt att bedömaren använder sig av ett validerat instrument som täcker flera aspekter av återhämtningen.Syfte: Vårt syfte med studien var att i litteraturen identifiera bedömningsinstrument för uppföljning av patientens postoperativa återhämtning.Metod: För att besvara syftet gjordes, i denna pilotstudie, en systematisk litteraturstudie med sökning i databaserna Chinal och PubMed.Resultat: Denna pilotstudie resulterade i att 11 instrument kunde identifieras som på olika sätt bedömer patientens postoperativa återhämtning. Ur dessa bedömningsinstrument kunde 6 huvudkategorier med bedömningsfaktorer urskiljas. Dessa var; smärta, fysiologiska faktorer, fysisk aktivitet, emotionella faktorer, illamående/kräkning samt nutrition/elimination.Konklusion: De flesta instrumenten vänder sig direkt till patienterna.

Vad är en sinnesträdgård? : ansats till framtagande av de utmärkande egenskaperna hos fenomenet
The purpose of this paper is to find the true meaning to the Swedish word
"sinnesträdgård" as a fenonomen. This paper concentrates on the Swedish use of the
word, because the term has different definitions in other countries. Our choice was a
phenomenological method after reading literature on, and in relevance with, the subject
without finding an answer to the question. According to our six informants - a politician,
a project manager, two landscape architects and scientists, and two occupational
therapists, the concept has not yet been defined.
The results show that a "sinnesträdgård" is complex and means several things, but the
main purpose of the concept and place is to stimulate all senses. We have discussed how
to distinguish the concepts "sinnesträdgård", design garden and health garden, from each
other as they all stimulate the senses.

This thesis treats the development of, and contingencies for, a mobile phone directory, using the limited resources found in a mobile unit. The project was implemented and executed at The PhonePages with the intention of creating a product to sell to a third party.By studying different solutions, their benefits and drawbacks, an abstract picture of the product was constructed. Problems covered include compatibility problems caused by todays platform diversity as well as problems with saving, organizing and presenting data.The main goal was to create a phone directory which does not make external information retrievals. The service should contain both company and personal information, with name and phonenumber.
Isolerande och skyddande dubbelväv - Produktutveckling av ett kylande fodral
Denna rapport beskriver en produktutvecklingsprocess som behandlar utvecklandet av ett textilt material som isolerar och skyddar. Det textila materialet ska fungera till ett kylande fodral utan att förstöra dess funktion och behöver därför uppfylla en speciell kravspecifikation. Materialet ska isolera mot kroppsvärme, vara stabilt, skyddande och slitstarkt. Dubbelväv valdes tidigt i arbetet då det är ett enkelt sätt att kunna påverka det textila materialets egenskaper i form av material- och konstruktionsval, i en betydligt större utsträckning än i en enkelsidig väv. För att utveckla ett material med de efterfrågade egenskaperna har tester utförs och den metod som har använts är hypotesprövning.
