Illiterata invandrares informationspraktiker
The subject of this two year Master's thesis in Library and Information Science is the information practices of illiterate immigrants in everyday life. The purpose is to examine how immigrants seek, identify, understand and value information sources and information, and how the practices have changed with their arrival in Sweden. It furthermore focuses on the barriers that illiterate immigrants meet in accessing and understanding information. It moreover investigates the strategies they use to overcome them.For this purpose twelve qualitative research interviews were carried out, with illiterate immigrants as well as with service providers. The theoretical concepts of the essay is information practices, which means that the information process is within a context, and information poverty, that people in different context do not have adequate and equal access to information and information sources.Using McKenzie's model of information practices, the essay concludes that illiterate immigrants are active in their information process, especially when they interact with information.
"De vill oftast inte göra som man säger? " : Sjuksköterskans upplevelse av att vårda äldre personer med kronisk hjärtsvikt i akut slutenvård
Bakgrund: Hälso- och sjukvårdslagen fick år 2010 en ny paragraf som resulterat i nya riktlinjer i flera av Sveriges landsting angående bemötandet av barn som anhöriga. Årligen förlorar 3361 barn en förälder på grund av svår sjukdom och detta kan resultera i en sämre fysisk och psykisk hälsa hos barnet. En ökad medvetenhet inom sjukvården skulle möjliggöra igenkännande och stöd till drabbade barn. Syfte: Att beskriva hur barn hanterar sin situation då en förälder är svårt sjuk och hur sjuksköterskan kan stödja barnet. Metod: En litteraturöversikt baserad på 13 studier med kvalitativ ansats.

This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.

Hjärtsviktspatienters följsamhet till, samt beskrivningar och upplevelser av, att följa icke-farmakologiska behandlingsriktlinjer ? en litteraturstudie
Bakgrund: Hjärtsvikt är vanligt förekommande i den svenska befolkningen och är den vanligaste orsaken till sjukhusinläggning. Bristande följsamhet till den farmakologiska hjärtsviktbehandlingen är idag ett stort problem inom sjukvården. Detta bidrar till ökade sjukhusinläggningar samt ökad dödlighet hos hjärtsviktspatienterna. Icke-farmakologisk behandling har dock kunnat ses som ett komplement till den farmakologiska behandlingen.Syfte: Syftet med denna litteraturstudie var att beskriva patienters följsamhet till, samt beskrivningar och upplevelser av, att följa icke-farmakologiska riktlinjer i samband med hjärtsvikt. En granskning av kvaliteten beträffande de inkluderade studiernas undersökningsgrupp utfördes även.Metod: En beskrivande litteraturstudie där 12 vetenskapliga artiklar inkluderades.
Förbättrad lönsamhet i växtodlingsföretag! : en ekonomisk analys av ett samarbete i form av ett driftsbolag mellan två lantbruksföretag
The agriculture is today in a development that leads to bigger and bigger units in the primary production. To be able to follow this development many companies chooses to cooperate in different ways. The most radical change is when farmers fuses with other farmers and merge into to a big collectively owned operation firm. The reason behind this idea is that the firms achieve the big companies advantages by being complement to each other. The purpose of this essay is to make an economic analysis of two crop production companies who works together in an operation firm.
PARAMETRISERAD DESIGN APPLICERAD PÅ EN MOTORSÅGSKEDJA
The main objective of this thesis was to develop appropriate strategies and find factors that affect the usability of parameterized designs. This was accomplished by investigate the user-interface and how it is designed to meet the user's information needs. The thesis also embraces the basic theories in terms of investigation, cognitive design principles and human behavior patterns in the interaction with the machine. The approach has led to an explorative investigation in this subject area.The thesis also had the purpose to achieve more efficient ways for development of motor chainsaws at Husqvarna AB's department Global Cutting Equipment. That can be achieved through reduce costs of development per sold unit.
Optimering av sintrade kugghjul
Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. The current master thesis work focuses on gear design using PM by utilizing finite element method (FEM) to reduce weight and inertia taking into account root bending strength and tooth deflection.First a topological optimization is used to determine feasible candidates for different web designs which have as objective to reduce volume, similar topologies were shown during different loading conditions; and hence, this topology was chosen as a suitable candidate. A shape optimization of the topological candidate was performed having as state variables root bending strength, independent for compressive and tensile side of the tooth loading; and tooth deflection, which in concept can be correlated to static transmission error (TE).Another aspect in this thesis analysed is the possibility to incorporate non-trochoid root geometry, a trochoid root is always present when machining with a hob, into the gear root and hence reduce the stress concentration here. Due to the use of PM, a non-symmetric optimized root can be achieved and hence be optimizing compression and tension.Results showed significantly lower inertia, for example certain results showed 40% reduced when compared to solid gear, with adverse effects as increase in tooth deformation and increase in maximum principal stress.
Egenvård hos patienter med hjärtsvikt
Hjärtsvikt tillhör en av Sveriges stora folksjukdomar och är den vanligaste inläggningsorsaken på sjukhus bland personer över 65 år. Hjärtsvikt är ett tillstånd där hjärtats pumpförmåga inte kan försörja kroppens vävnader med tillräcklig mängd blod. Patienter som lider av hjärtsvikt går en förändrad livsstil till mötes. Därmed behöver dessa patienter mycket information och kunskap för att öka delaktigheten och kunna planera och genomföra egenvård. Sjuksköterskan måste därför uppmärksamma och undersöka på vilket sätt och med vilka faktorer detta kan uppnås.
Optimization of Burner Kiln 7, Cementa Slite
In this report focus is put on the combustion process at a cement plant. Combustion is the
heart of the cement making process and absolutely crucial to have under full control and well
optimized.
The fuel is put into the process through a burner pipe and this burner pipe is modified to
reach a more efficient combustion. The primary target is to enable burning of heterogeneous
alternative fuels and increase the production level. Other positive effects from this type of
optimization is lowered specific fuel consumption and lowered CO2 emissions.
A redundant burner is chosen for the project and overall the project steps are the following:
1. Installing a Jet air nozzle ring in a way so it can move both axially and radially due to
temperature changes.
2.

Implementering och verifiering av kvantitativ ELISA för analys av Staphylococcus aureus enterotoxin A och C
Varje år uppskattas en halv miljon svenskar drabbas av matförgiftning och knappt en tredjedelrapporteras ha drabbats av en matförgiftning orsakad av bakterier eller bakteriella toxiner.Under år 2007 drabbades drygt 2500 EU-medborgare av matförgiftning orsakade avstafylokockenterotoxiner (SEs). I livsmedel har man sett att produktion av SEs framförallt ärkopplat till Staphylococcus aureus. Studier har visat att SEA följt av övriga klassiska SEs ärde toxin som oftast orsakar matförgiftningar.Detta kandidatarbete har haft som mål att sätta upp en ELISA för kvantitativ bestämning avstafylokockenterotoxin A och C i BHI-buljong (brain heart infusion) och pastöriserad mjölkmed fetthalt 1,5 %. Ytterligare mål var att fastställa nedre gränsen för att kvantitativtbestämma enterotoxininnehållet med använd ELISA. Detta för att kunna jämföraenterotoxinproduktionen hos S.

Inte för alla -? En kvantitativ studie om journaliststudenters representation av allmänheten i Nicaragua
In our bachelor thesis we have strived to examine the representation of journalism students in Nicaragua. The freedom of press is much lower compared to Sweden and the journalist profession is protected by a certificate. It is also a high level of corruption within the country. Our investigation concerns who has access to the journalist education and the goal is to compare that with the public in Nicaragua. To be able to examine the representation among the journalism students we have chosen seven different aspects to examine, the sex of the student, witch social class they belong to, their academic background, religion, ethnicity, geographical belonging and political view.
