Hisskärna av skalväggar i höga byggnader : Ett alternativ till den platsgjutna kärnan
A common way to stabilize high rise buildings is to use an elevator core built of concrete. Today, we use to build these elevator cores of in-situ concrete. Precast concrete twin wall (double wall) is a semi-finished product that has become more common in recent years. This diploma work studies how the twin wall works out as structural elements in an elevator core. The work also shows some possible ways of designing twin walls and highlights some important parts of the design that will be vital to the stability of the building. The result shows that it is important to think through where the element joints should be placed.
Sjuksköterskans arbete med Manchestertriage : arbetstillfredsställelse och kompetens
Background: Triage is the sorting of patients according to the severity of medical assessment. Triage has a long history of use in Anglo-Saxon countries but is a fairly new method in Sweden. Researchers have described the Manchester triage group method (MTS) and a literature review of the concept; working contentment and competence focusing on triage. Aim: The ambition with this study was to describe a number of triage nurses working conditions. The research questions were; working with MTS- does it bring work contentment? What kind of competence is needed? Method: Data was collected from 74 triage nurses by a questionnaire containing 37 questions and two questions provided the nurses the opportunities to describe their triage experiences.
Ethics and Animal Experimentation in the Laboratory. A Critical Analysis of the Arguments for"Animal Rights"and"Animal Equality"
Growing up as a child, we had a Dog. To us, it was like a means to an end. That is, hunting other animals for food and for protection, with no special care and treatment given to this animal. Butas days passed by I began to witness a wind of change against such actions. I was made to understand that we were committing two crimes-: using the Dog as a means to an end (for hunting and for eating animals).
Anhörigvårdares Upplevelser Av Sitt Vardagliga Arbete
The family and relatives caring of older people in Sweden lies on an old tradition. By legislation the responsibility for the older people has gone through a development from the family to the society. According to the new social service law (2000) it is not that clear that the utmost responsibility lies on the society. According to the social service law ( 5th chapter, 10 §) the municipality should ease things up by giving support and relief for relatives taking care of older people, prolonged ill and function disabled people. The purpose with the study was to examine how the family care givers are finding their everyday work and their experience of the support that the society is giving.

We strategic selected three social workers and four managers to our interviews.The results showed that both social workers and managers have experience with child welfare investigations that are not completed within the statutory time. A township that departed had no experience.
Konstruktion av provladdare till singelmolekyldetektor
This report describes the development of a sample loader for my diploma work at Q-linea AB in Uppsala. The sample loader will replace the process of loading fluid samples into Q-linea?s instrument for biomolecule analysis. The earlier process was done by hand and was a time consuming and inefficient task.The work was initiated with a design phase where an overview of the system was created. The sample loader will be receiving text commands from a PC that coordinates all the subsystems like pumps and lasers on the analysis instrument.
Förluster av nedströmsvandrande fisk vid turbinpassage : En fallstudie för att främja den småskaliga, såsom storskaliga vattenkraften
The expansion of the Swedish hydro power has contributed positively to the reduction of the environmental impacts from the fossil fueled power production. In the same time the extensive expansion has been proved to cause negative ecological and local environment impacts of a stream. This, in turn, has been affecting the biodiversity and fish stock negatively, which has been reduced. One of the underlying problems is the lack of possibility for the fish to pass the plants, but it is also directly correlated to the mortality rate of the fish passing through the turbine, which this study is investigating.The mortality rate has been computed for three different locations in Sweden, Untra, Tännfallet and a third one whose location is confidential, and is denoted as Case 1, 2 and 3. The model used to calculate the mortality rate in this investigation is based by existing blade strike models and knowledge and are investigating the death due to mechanical injuries from collision with a runner blade in the turbine.
Är egenföretagande en riskfaktor för alkoholmissbruk?: en studie om egenföretagande och dess villkor kan vara riskfaktorer för alkoholmissbruk
The aim of this essay was to obtain an understanding about company owners thinking about the connection between having an own company, and the risks for an alcoholic abuse. The risk factor I was researching was stress, alcoholic culture, accessibility and rehabilitation.I have interviewed five owners of small companies, two women and three men, which represents four different kinds of branches. The theories I used in analysing the empirical findings where the theories of psychosocial work environment of Lazarus, Karaseks demand/control model, epidemiology- and culture perspective.I have found that the main stress factors for company owners where the economical stress and great load of work. The stress was also related to the fact that company owners of small companies often were alone with all the responsibility and problems.Women did not use alcohol very often as a tool to reduce stress. If individuals were using alcohol to reduce their stress, it also had to deal with their ability of coping and also what channels they had for coping..
Experimentella och teoretiska uträkningar för skruv- och bäddhållfasthet för takinfästningar mot stålstomme
Lättelement located in Örnskoldsvik AB is one of Sweden's leading companies in the development of building elements in the form of roofs, walls and floors made ??out of light beams. The company has clients from Lund to Kiruna, and from Norway. This means that the elements have high standards when they have to take many different loads from wind and snow due to such wide geographic variation.The roof elements are structured so that the main body is made of light beams with an I?profile.
Utveckling av 300 kg HD Lightlift för belysning och liknande laster
The company LightLift Esystems AB manufactures patented motorized lift systems for the illumination of halls with high ceilings. The company wants a new design for singular heavy lights in order to be more competitive.This project consists of the development of the new design under the requirements and specifications imposed by the company. The new design must support lights up to 300kg and keep the overall dimensions as low as possible without modifying the driving unit.This document contains all the designing steps followed to reach the final solution as well as the material selection, manufacturing process and assembly of all the parts that form it.The solution obtained shows to be very competitive with other alternative products, since this new design triples their maximum load capacity while the dimensions are very similar.In this context, the optical appearance was also very important to the company and so it was another main objective of this project. From an aesthetical point of view, the final solution proves to be very compact and versatile since it can either be hidden behind a false ceiling or covered by a plastic case that gives the design a very nice look.Finally, the solution achieved fulfils all the requirements and specification previously imposed. It is reliable, compact, cheap to manufacture, easy to assembly and it has a good optical appearance. .
Utvärdering av simulatorer och emulatorer för inbyggda system
Uppdragsgivaren Saab Electronic Defence Systems i Jönköping erbjuder ett flertal produkter främst inom avioniksystem. För att kunna utvärdera och kontrollera produktens design i ett tidigt skede så kan en simulering av systemets beteende och att felsöka så tidigt som möjligt vara ett möjligt alternativ. En systemsimulering kan innebära att mjukvaruutveckling och felsökning kan påbörjas långt innan hårdvaruprototypen är tillgänglig, med samma storlek och komplexitet som systemet.Andra fördelar med simulering är att det går enklare att fastställa orsaken till systemkrasch, hitta de längsta exekveringstiderna och göra felinjiceringar. Syftet med detta examensarbete är att testa och utvärdera hur simulatorer och emulatorer är som utvecklings- och testverktyg.Rapporten innehåller en marknadsundersökning där tio stycken emulatorer och simulatorer hittades. Av dessa valdes två stycken ut, Wind River Simics och Imperas OVPSim.

This report describes how the system may be exposed to oscillations and how this can lead to resonance. Resonance is a phenomenon that occurs when a system is affected by external periodic oscillations with frequencies close to the system's natural frequencies. Structures subjected to resonance can risk great damage and destruction, why resonance is something that is important to take into account when designing structures. Alternative ways to counteract resonance is to supply damping in the system. Damping means that the resonance decreases instead of letting the amplitude increase.The report discusses some examples on constructions that have experienced the effect of resonance.
Att trivas i orkestern : En fallstudie om gemenskap och sammanhållning i en ungdomsblåsorkester
I denna studie undersöks hur gemenskap och sammanhållning i en ungdomsblåsorkester ser ut och hanteras både utifrån orkesterledarens och de deltagande ungdomarnas synvinkel. Även betydelsen av gemenskap och sammanhållning och hur den tar sin form är frågor som besvaras i uppsatsen. Datamaterialet består av intervjuer med olika grupper av ungdomar ur den studerade ungdomsorkestern samt en intervju med orkesterns ledare. Den studerade orkestern kommer från en stad i mellersta Sverige. I resultatet visas att det är viktigt med en orkestergemenskap och att gemenskapen fås och visar sig i både sociala och musikaliska aktiviteter som bland annat resor, läger, fikastunder, repetitioner och konserter.
