Detta är ett examensarbete som genomförts hos Göteborg Energi AB och syftar till att utreda omkryogen uppgradering av biogas med fördel kan ske genom att producera nödvändig kyla medvärmedriven absorptionskylmaskin. Göteborg Energi är en av tre parter som tillsammans ska bygga enbiogasanläggning i Lidköping som ska vara i drift 2010. Anläggningen ska producera 30 GWhflytande biogas per år.Arbetet utreder om det är fördelaktigt ur ekonomiskt, energimässigt och miljömässigt perspektiv attuppgradera biogas med kryogen teknik med värmeproducerad kyla. En jämförelse görs först medkryogen teknik där kylan är producerad med el och sen med andra uppgraderingstekniker. Som stödhar två olika processimuleringsprogram används, Hysys och DESIGN II.Resultatet visar att energianvändningen ökar då värmedriven kyla används i jämförelse med kylaproducerad med el.

Miljöcertifieringssystemen PEFC och FSC ställer krav på uppföljning och revision för att säkerställa att kraven och kvalitén uppnås. Studiens syfte var att belysa de skogliga maskinentreprenörerna och förvaltarnas/virkesinköparnas erfarenheter av arbete med uppföljning inom miljöcertifierat skogsbruk. Materialet insamlades genom telefonintervjuer och analyserades med kvalitativ innehållsanalys, vilket ledde fram till resultatet. Uppföljningen och traktdirektivet har en viktig roll för att nå miljöcertifieringarnas krav. Dialog och delaktighet mellan de olika yrkesgrupperna var viktig, enligt respondenterna, för att miljöcertifieringen ska nå en hög kvalité och för att skapa engagemang och vilja att förbättra arbetet..

SMTP, the current protocol for sending electronic mail (e-mail) over the Internet, has for many years suffered from several problems and limitations. When it was designed, well over twenty years ago, the requirements for e-mail were very different from those of today. A message was a text message in English, and both user and machine were explicitly named in the address. The protocol was not designed to transfer other types of messages, and no mechanism was included to verify the identity of the sender.In order to solve these shortcomings, a new e-mail protocol needs to be defined. This report specifies a basis for what such a protocol may look like.

The purpose of my study is that I have examined children age 4 years and 5 years of their perceptions about the body's internal organs, and if they know where they are sitting in the body, and what their perception of organ systems. I have compared their perceptions and thoughts about the internal organs, to see their similarities and differences it is about childrens perceptions and thoughts dependent if they is 4-respektive 5- years old.The results that I got from my examination was that they showed me a big variety by their earlier perception about the organs. Some had knowledge of the name, some had of the function and some of the place of the organ brain, heart, lungs, stomach, liver and intestines. All these knowledge about the organs was a variety on and you could see similarities and differences in the different ages. One example about a different is that it was a four year old child that could the name of the stomach and the stomach function while there was three five years old children that could the brains name, function and place..

COPD (Chronic Obstructive Pulmonary Disease) is one of the most widespread lung diseases today and is a growing cause for suffering and mortality worldwide. It is considered to be the third leading cause of death in the near future. Smoking is the most important risk factor for this disease and about 50% of smokers develop COPD. The purpose of this study was to mediate the experience of not being able to stop smoking described by persons diagnosed with mild or moderate COPD. The study involved five women and five men.

Bakgrund: Lungcancer är den femte vanligaste cancerformen i Sverige, med dålig prognos och leder ofta till döden. Då bot inte längre är möjligt blir palliativ vård aktuellt. Detta betyder att patienten bör vara fri från smärta och plågsamma symtom, att man varken påskyndar eller skjuter upp döden och att döendet ska ses som en normal process. Syfte: Syftet var att beskriva patienters upplevelser av att leva med lungcancer i den palliativa fasen. Metod: Studien genomfördes som en litteraturstudie (overview), baserad på empiriska studier inom det valda ämnet.

This essay investigates the results of participation by teenage girls in feminist groups, the so called girl groups. These groups are descendants of the awareness-raising groups of the 1970?s feminist movement. The essay assumes the relevance of theories of heteronormativity and performativity, as well as theories surrounding two different ways to organize girl groups. It is done either through the Pippi-feminism, named after strong independent book character Pippi Longstocking, or through the collective empowerment feminism.

Syftet med denna studie var att påvisa vilka känslor som väcktes hos föräldrarna inför sitt barns hjärttransplantation och hur deras upplevelse av informationen från vårdpersonalen uppfattades. För att kunna genomföra undersökningen användes en anonym enkätundersökning med semistrukturerade frågor. Undersökningens deltagarantal var litet på grund av att få barn blivit hjärttransplanterade på hjärtcentrat. Av sexton tillfrågade föräldrar svarade endast åtta på frågeformulären. I resultatet framkom att föräldrar under kontakten med hjärtcentrat hade både positiva och negativa upplevelser.

A well known optimization-problem of multiprocessor system is scheduling of tasks. In this paper I use a variant of previous known algoritm, (Fast Critical Path) for scheduling real-time tasks on a multiprocessor system. This is made in a simulation study in MATLAB. The system architecture is assumed to be a MIMD- machine, (Multiple Instruction stream Multiple Data stream) with bus-typologi and message-architecture. Scheduling was made on this system where the number of processors varying from five to ten.

This degree project was conducted in collaboration with Gremo AB located in Ätran.The aim of the project was to develop a solution to secure quality and to help assemblingthe locknut holding the vertical hinge on the harvesters and foresters from Gremo.At this time the nut is assembled manually by the aid of an overhead crane. The nut istightened differently from time to time, and there was no specified torque to which it istightened. Another present problem was the locking washer which sometimes getsdamaged during assembly, when this happens the procedure has to be started over fromthe beginning. The current assembly procedure is very time consuming and lengthy forthe employees.Our task was to design a machine that could tighten the nut to a specified torque with amargin of error of ± 3%. The assembly procedure will be held simple and the timerequired at a minimum.The project started by developing several principle solutions, the one solution that bestmatched our specifications were developed to a primary solution.Today we have started manufacturing and assembling our prototype.

This examination work is about an marketing investigation of John Deere Moco 730/735 during the season year 2003. Moco 730 has an workingwidth on 3 m, and 735 has one with 3,5 m. The research results of 16 moco 730/735 are from intervju- and questionnaire made of the owners. The results also comes from intervju anwser from dealers which sold this mocos. The examination work shows comments and opinions from the customer after one seasons use. In the end of my examination work are all comments and opinions put together in a marketing analysis called swot-analys in Swedish. The analysis declare that the moco 730/735 is functional and have god quality. The future seems god for this kind of moco. The strength for this moco are god quality and the dealers god service support. The most important weakness about this moco are that the machine came out late on the market, compared to other mocos on the market. I think it´s important the have in mind that the customers are very John Deere faithful and this JD 730/735 is used for only one season..
