Aeroseum is an aviation museum located in an old military underground hangar. The ventilation system in the hangar is designed for the military purpose of the hangar. This design includes a solution with air flowing through the space between the construction of the hangar and the rock surface. The solution is intended to avoid a buildup of inflammable gases. This design leads too high humidity levels in the hangar.

The Homogeneous Charge Compression Ignition (HCCI) engine is promising in terms of lowNOx, low particulates and high efficiency. Due to its homogeneous charge, where thecombustion starts almost simultaneously from a number of points in the combustion chamber,only lean mixtures are possible to burn because of the resulting rapid combustion, which is muchfaster than the combustion in an SI-engine or a diesel engine. When richer mixtures are used thecombustion will start earlier and also be more violent.To phase the combustion later and lower the combustion speed, external cooled EGR can beused. The EGR-system used in this thesis uses a divided exhaust channel where one channel andits corresponding valve are used only for transporting EGR back to the intake system.Consequently the EGR-valve is connected to the intake pressure. This system is called Direct-EGR (D-EGR).Engine tests verified that the CA50 indeed is phased later when cooled EGR is used.

Syftet med litteraturstudien var att ta reda vad olika studier kommit fram till angående patientutbildning om diabeteskost, motion, hur patientutbildningen bedrivs och uppföljning av vad patienterna fått med sig för kunskaper genom utbildningen.

Vid sökningen gjordes begränsning till svensk, norsk och engelskspråkiga tidskrifter och alla artiklar var vetenskapliga. Sökorden som användes i olika kombinationer var: patient education, diabetes, education, exercise och diet. I de artiklar som hämtades via databassökningen valdes ytterligare artiklar från referenslistor.

This essay examines whether feminist theory can give a plausible answer to the question: does female and male students have different attitudes towards the labour market and towards wages? Further more, I examine if factors such as class and ethnicity affect student's attitudes. These questions are investigated through a quantitative study of students at four educations on two different universities in Sweden. Two of the educations have a high degree of female students, and the other two represent educations with at high degree of male students.The main conclusion is based on the quantitative research results. Female and male student's attitudes are similar in some cases.

The aim of this study is to analyze how problems are represented within SOU 2008:27. Further more, the aim is to analyze how the new subject plan for history can bee seen as a product of this document. The method used, and the theoretical frame of the study, is based on Carol Lee Bacchi?s ?what´s the problem represented to be?? approach, which basic principle is that policies are filled with representations of problems and that these representations need to be examined. These problem representations are then themselves subject for scrutiny, the second step being an analysis of the texts presumptions and assumptions concerning view of man and perception of knowledge. The results show, among other things, that a problem representations can be found in the SOU; the school system is too vague and unclear.

The purpose of the present study is to describe adult second language learners? experiences of mathematics learning from a past and contemporary perspective. What experiences in mathematics do they bring? What does it mean to learn Mathematics through their new language?The study is based on life-world narratives from five second language students with another native language than Swedish. Today they all study at a Swedish folk high school, at upper secondary level and they have previously studied at this level in Mathematics. The result shows that the meeting with the Swedish school and folk high school context is confusing.

Det finns idag fler personer som heter Johan som är VD i börsnoterade bolag än vad det finns kvinnliga VD:ar i Sverige. Uppsatsen är skriven om ett stort svenskt företag i näringslivet. Syfte med studien var att utvärdera varför kvinnliga chefer på höga positioner inom ett större svenskt företag i näringslivet har valt att sluta samt vad företaget kan förbättra för att bli en mer jämställd och attraktiv arbetsplats för kvinnor i chefsbefattningar. Forskning visar på att det idag 2013 fortfarande finns en hel del ojämställda arbetsplatser. Via kvalitativa semi-strukturerade intervjuer med sju kvinnliga före detta chefer på företaget har en bild av vad detta kan bero på skapats.

The market for heavy duty engines is constantly requiring engines that should be more andmore powerful, while still maintaining low fuel consumption. As a result of increasing enginepower, the engine and coolant temperature increases as well due to insufficient coolingperformance (because of design issues, cost etc.).Also, emission legislations, both current and future, require more and more measures to betaken by engine manufacturers. One way of meeting the legislations is the use of cooled EGR(Exhaust Gas Recirculation), which also lead to increased coolant temperatures.Both these factors also naturally lead to increased engine oil temperatures, the consequencesof which are not thoroughly investigated.This thesis project aims to investigate effects of high temperatures on engine oil degradation,with focus on the greatest degradation process: oxidation. To do this several engine runs havebeen performed on a 310 hp engine with EGR to see what happens to the engine oil in a realengine when exposed to high temperatures. During the tests oil samples have been taken andanalysed for important parameters.As a complement to these engine tests some laboratory oxidation testing have also beenperformed, to be able to compare engine test data with laboratory tests.One goal of the project was to try to formulate an empirical oxidation model, which would beable to predict oil oxidation levels in an engine, given any running parameters.

This thesis is divided into two parts. Part one contains a general description of the flexographic printingtechnique. Part two contains a more detailed investigation in the areas substrate, inktransfer and trends, which are only briefly commented in part one, and conclusions and comments.The major problem concerning substrate is washboard. This phenomena can be limited if one can control and minimize the amount of glue applied in the single- and double facer, use high surface weight on liner, use low surfaceweight on fluting and control the humidity during the conditioning of the corrugated board. Corrugated board with a smooth surface radically increases the quality in print.

Bakgrund: Patient i hemodialys (HD) behandling är utsatt olika stressfaktorer, som tillexempel den strikta diet, begränsat vattenintag, bundenhet till dialysenhet eller känsla avtrötthet även på dialysfria dagar. Cirka 20 procent patienter i HD behandling utvecklardepression som i sin tur leder till låg plasma albumin.Syftet: Att belysa samband mellanstressfaktorer, depression, låg plasma albumin och mortalitet/morbiditet samt omvårdnadensbetydelse för patienter i hemodialysbehandling.Metod: Studie genomfördes som enlitteraturöversikt och granskning av vetenskapliga artiklar.Resultat: Resultat baserar på 15artiklar, varav 1 kvalitativ, 14 kvantitativ. Resultatet delades i fem kategorier: stressfaktoreroch deras koppling till depression, depression, låg plasma albumin, omvårdnadsåtgärder vidlåg plasma albumin, omvårdnadsåtgärder vid depression.Diskussion: I diskussion lyfts uppsamband mellan högre morbiditet/mortalitet och depression samt låg plasma albumin hospatienter i HD behandling.

Stillasittande utgör en hälsorisk i sig oberoende av andra hälsorisker som dålig diet och fysisk inaktivitet. Inom forskningen har man börjat undersöka hur vi påverkas av långvarigt stillasittande och vetenskapligt stöd finns för sambandet mellan långvarigt stillasittande och ökad risk för dödlighet, hjärt -och kärlsjukdom, cancer och diabetes typ II. Än så länge får inte stillasittande samma uppmärksamhet forskningsmässigt som liknande hälsoriskfaktorer.Syftet med studien var att undersöka stillasittande hos universitetsstudenter på LTU under en genomsnittlig dag.Studien utfördes på studenter som studerar vid på Luleå tekniska universitet. En enkät för att mäta stillasittande skapades utifrån två validerade enkäter. Under två dagar lämnades enkäten ut till studenter på campusområdet, 223 enkäter samlades in.Denna studie visar att studenter på Luleå tekniska universitet, kvinnor som män var lika stillasittande, med genomsnittligen 10 timmar per dag.

By examine plastic craniums from eight different hominids I wanted to find morfological characteristics that agreed with those of modern humans. The species that were selected had a plastic casting of its cranium in the laboratory at Gotland University. My focus was on species from the family Australopithecius and Homo and only working with their craniums. And this because the cranium and the theeth shows the most visible morfological characteristics between the different hominids. I also wanted,in a small part of the essay, to write about the differences in now living primates and humans skulls.Except from analysing the plastic castings I also studied surveys written by other scientist on the same subject.

BACKGROUND: Today?s societal changes, including high rate of change and increasing information flows, are increasing the demand on the individual mental capacity. It becomes increasingly difficult to analytically process all the different dilemmas and everyday decisions as individuals have a limited mental capacity available to make these decisions. Thus, it has been suggested that ego-depleted relies more heavily on intuition, which is less burdensome, when making decision. However little is known about to what extent intuitive decisions differ from analytic.

The background to this final thesis is that our mandator, A-hus, was interested to examine which roof system that would be most appropriate to their types of houses. To investigate this, we first conducted an evaluation of the most commonly used roof systems in Sweden today: decking, board, roof cloth and prefabricated roof cassettes.To gather information about the different systems we have conducted interviews with several professionals within the construction industry, done an extensive literature study, and gathered information from the Internet.Based on the evaluation of roof systems and the literature, we analyzed advantages and disadvantages of the roof systems from three main perspectives: system characteristics, economics and other characteristics. We found these perspectives to be the most relevant when selecting a roof system.The main perspectives comprise three categories which are graded. These grades are then added together for a score for each main perspective and a total score for the three main perspectives. Then we compared the systems and, based on the scores, suggested one roof system as the most suitable for A-hus.Our result suggests that the prefabricated roof cassettes probably is the best solution for A-hus, but only if it is possible to standardize the cassettes and still maintain the flexibility to match A-hus? house types.
