Vegetarisk kost - om sjuksköterskors kunskaper. En empirisk studie.

The purpose of our study was to establish whether the knowledge about vegetarian diet was enough among nurses in order to practise professional nursing. We made an empirical study based on a questionnaire. Twenty-one registered nurses answered the questionnaire that consisted of mostly open questions. The result showed that almost everyone experienced that they gave dietcounselling and many nurses mentioned that dietcounselling was important. The majority of the nurses thought that they had enough knowledge to be able in order to deliver a fundamental dietcounselling but nobody considered that they knew much about vegetarian diet..

Studie av belagda kolvringarmot plasmasprutat cylinderfoder : Med avseende på friktion och nötningsmotstånd

Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

Betydelsen av skogens ålder och förekomst av lavar för renars val av vinterbetesområde :

This is a study on winter groups, ?siida?, of semi-domesticated mountain-migrating reindeers that move to lichen pastures in the lowland boreal forests during winter. The aim of the study was to determine reindeer habitat use in their winter ranges in a managed forest landscape. The reindeers use of three different types of forests was determined, 1) 100-130 year old, 2) 20-40 year old forest and 3) clear-cut areas. All sites were dominated by Scots pine, Pinus sylvestris, and had the same types of ground vegetation.

Folkbibliotekariers användning av sökverktyg på webben i referenstjänst

The web is a constantly growing medium that presumably plays an increasing role in public library reference services. In order to provide high quality reference service the librarians need to be able to master this medium. Therefore it is interesting to get an understanding of how librarians actually use the web. The aim of this Master s thesis is to investigate what web search tools are used by public librarians in reference service. Furthermore, the aim is to get an understanding of how the librarians think about those tools and what background factors influence their selection of tools.

It focuses on how the children actively participate in the process of shaping family life and their own childhoods in the context of family change.

"Kränkningar går som i en cirkel hela tiden!" : Elever undersöker begreppet kränkningar i en fokusgrupp genom drama.

I mitt examensarbete har jag valt att försöka undersöka i vilken utsträckning det i en hemmastudio är möjligt att återskapa ett sound från en professionell inspelningsstudio. Denna fråga är intressant för mig då jag fastnade för hur en produktion lät i ljudbilden. Dels instrumentuppsättningen och deras rytmisering men främst soundet på helheten i mixen. Det kändes luftigt, stort och brett i lyssningsspektrat trots att det inte var så mycket instrument. Jag har alltid velat utveckla min förmåga att skapa och producera musik men har inte tillgång till så mycket kvalitativ utrustning.

Dialektanvändning hos barn med typisk utveckling : En jämförande studie mellan östgötska barn i olika åldergsgrupper

To explore how children use dialect, and whether the dialectal language develops during growth might be of interest from a speech language pathologist?s point of view as the dialect could influence the child?s speech. Previous research is often based on older material and/or examines the speech of adults.  In the present study, everyday language in groups of south- eastern Swedish speaking children was investigated. The aim of the present study was to examine to what extent typically developed children of the ages of  5, 8 and 11 years use dialectal language. A further purpose was to discover which dialectal characteristics that were present in the different age groups, and how they differed.

Den olfaktoriska l?sningen. Lukt i Sara Stridsbergs Happy Sally

This essay examines the olfactory reading as a possible way to make sense of a fragmented novel, in this case Sara Stridsberg?s debut Happy Sally (2004). Through close reading, the essay identifies the source of the smells, who perceives it, and how this is portrayed in the text. The smell?s position in the text is understood in relation to Maurice Merleau-Ponty?s phenomenology, where the body, as created in the literary text, is considered as a source of knowledge.

Gruppdynamik, medtävlare samt tävlingssituationer : En motivationsfaktor till ökad prestation

Forskningen angående gryppdynamikens inverkan på högintensiv träning är liten, vilket skapar problem i samband med den ökade träningstrenden. Det har nu uppstått en ny arena att forska på.Genom experimentella studier studerades individers motivation samt prestation i olika försatta situationer. 10 deltagare utförde samtliga under sammanlagt tre tillfällen ett förutbestämt pass under olika förutsättningar (se bilaga 1). Studien innebär således tre likadana passutföranden.Genom intervjuer samt kartläggning av tider sammanställdes data vilken kom att beskriva samt förklara hur och varför deltagarnas prestationer kom att skifta. Resultatet kom att analyseras med hjälp av studiens teoretiska ramverk angående tävlingssituationer av Weinberg & Gould (2011) samt flertalet motivationsteorier.Studien visar tydliga samband på att prestation samt motivation ökar då deltagarna utför passen med medtävlande, samt i större grupper.

Projektverksamhetens"early-warner"- en jämförande studie om projektcontrollerns funktion

Background: The project controller is a function witch evolved due to the strong gaining ground of project operation. Why the area of the project controller is interesting to study is explained by the fact that increasing knowledge of this function is important in order to make project operation work well. The fact that opinions in this field disagree, further increases the interest of the field. In order to study the function of the project controller three companies have been singled out. They are IFS, Intentia and Saab Bofors Dynamics.

Nollföljdsmodellering av transformator-Beräkningar av följdproblem vid ökad kablifiering på mellanspänningsnivå

Historically transformers with system earth equipment have been modeled as open circuits in zero sequence. This approximation has been satisfying, but lately it has been discovered that equipment on one side of the transformer have responded to faults that occurred at the other side. Most of these problems took place when the majority of the system on the secondary side of the transformer contained cables. These findings have led to questioning whether or not the former model of the transformer in zero sequence is correct. This report investigates if it is necessary to represent the transformer in zero sequence in another way than it is usually done today.

Price adjustment and vacancies on theStockholm market ? Estimation of rent levelsdue to office-allocations

The Stockholm office market segment have for a long time been considered a safe havenwhen it comes to withstand negative turmoil in the form of rental compression due toeconomic fluctuation, especially in the CBD demographic. Recently however, a large numberof banks and institutions, amounting to some 200000 square meters, have decided to relocateto more peripheral locations with the aim of cost reductions on rent. This mass exodus isstudied with focus on rental dynamics as the result of increased vacancies. Other variables arestock changes and employment. The method is econometric combined with an interviewseries.

Utvärdering av ett Bränslecellsdrivet Flygplan.

 With the increases in fuel costs due to the depletion of the world oil reserves and the increase of greenhouse gasses as a consequence to using oil as a fuel many companies are looking to new and innovative ways to power their aircraft. One of these new ways to power an aircraft is using fuel cells powered using hydrogen and oxygen, thus producing nothing but water vapour and small amounts of nitrogen dioxide as well as trace amounts of other emissions. Both Boeing (1) and Politecnico di Torino (2) have shown that it is possible to build an all-electric aircraft powered by fuel cells. Both flights used small, two-seater aircraft and a constant between them was the loss of the co-pilot seat due to weight and lack of space. As this paper will deal with a commercial aircraft a primary concern is the cargo and passenger capacity and whatever impact switching propulsion system has on these.

Vad hör du? : ljudets betydelse för en plats

We are surrounded by sounds. There is always something that makes a sound: a breeze through the leaves, traffic on a distance or your own blood rushing through your veins. Human will always be surrounded by sounds which makes it an important part of our lives. Therefore the sound should have a big influence on how we perceive our surroundings and interpret our world. This essay inquires into what sounds can mean to an open space and urban spaces.

Skarven : ? Produktutveckling av en oljedimavskiljare

This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.
