Stenmaterial vid asfalttillverkning

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

Utvärdering av digitala provtryckssystem

Six different Digital Proofing Systems from three different techniques have been evaluated as totechnique, printing quality, economy and usability. Digital proof from two paper qualities, coatedand uncoated, has been compared with references printed in offset, to see how good they match eachother. Only two Proofing Systems manage to print on reference paper. The other Proofing Systemsuse special paper for digital proof.Measurements and visuell judgement show that the Digital Proofing Systems visualise referencepictures with quite good quality. Proof optimised for coated paper visualise the colours with goodresult.

Larynxmask eller endotrachealtub prehospitalt ? styrkor och svagheter : Litteraturstudie

ABSTRACTBackgroundWhen faced with an unexpected cardiac arrest the ambulance nurse is in responsible for taking advanced actions to create a clear airway. Two accepted methods for this is endotracheal intubation and application of laryngeal mask.AimThe purpose of this study was to examine the use of endotracheal intubation compared to application of the laryngeal mask in unexpected cardiac arrest.MethodLiterature study with quantitative approach. A systematic search of 21 articles comparing the laryngeal mask with the endotracheal intubation has been made using Pub-Med and CINAHL. A quality review according to Forsberg and Wengström has been made.ResultsLaryngeal mask had a higher rate of successful applications compared with endotracheal intubation. Time for applying the laryngeal mask was shorter in seven out of ten of the studied articles.

Fattigdomens slöja: En studie i hur fattigdom påverkar konsumtion

The aim of this study is to map the consumption patterns of the poor. We also examine if loyalty can be created in this segment, and try to discover different types of poverty. This study is of great importance since the poor segment has been slightly overlooked in marketing research. Therefore we have also turned to other academic disciplines such as sociology, ethnography and consumer culture in order to analyze our empirical input. The study is abductive and we have in a qualitative and ethnographical manner conducted interviews in order to obtain information and reveal categories.

Supermarket Strategies : Kvalitativ studie av Ica Maxi, Coop Forum och Citygross konkurrensstrategier

This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

"Det kan vara byta p-piller lösning, det kan vara ingen lösning alls... ingenting är svart eller vitt där" : En fokusgruppstudie om barnmorskors handläggning och uppfattningar av p-piller och biverkningar

Objective: To study midwives management, practice and reasoning regarding contraceptive counseling for women who are experiencing "mild" side effects of the pillMethods: Four focus groups, made up of three to five midwives per group, participated in focus group discussions. Qualitative design with the method ?Think-Aloud? has been used to collect data and the material was analyzed using content analysis.Results: The study identified three categories, the first "How midwives practice regarding the side effects of the pill," shows that midwives have a systematic approach when meeting with women who are experiencing side effects of the pill. The next category "Using a holistic and professional approach for women" highlights that the midwives take women's side effects seriously and that midwives respect individual woman?s autonomy.

Glöm inte barnteatern! En studie om barnteater på folkbiblioteket.

Samsyn, samarbete, samvaro eller sammanträde? Några lärares syn på ämnesgruppers arbete och organisation

The aim of this study is to examine the attitude among teachers towards working in subjectspecific groups, so called professional learning communities. The questions being asked arewhat the teachers want to acquire from working in them and how they consider them to beorganised.Previous research show that professional learning communities are means of strengtheningteachers and their teaching from criticism from outside stakeholders such as local politicians,but also parents. They are also means of developing the teaching and the individualteachers at schools.A qualitative study has been made at a Swedish secondary school and is reported in thisstudy. It was done in a hermeneutic discourse and when analysing the results four categoriesof answers appeared. It showed that the teachers working in professional learning communitieswanted to acquire a qualitative discussion regarding what should be taught and in whatway that should be assessed.

Genusmarkering av återgivet tal: Förutsägbarhet av förändringar vid litterär översättning från svenska till japanska

This thesis endavours to examine whether differences between original and translation in literary translation are systematic and predictable by studying a Swedish detective novel and its Japanese translation. The domain of the novel chosen for analysis is the reported speech (i.e. dialog).Translation Studies suggests that knowledge of the literary norms of the Target Language of the translation and of the status of translations in the Target Language's literary system, enables one to predict if and what differences between original and translation will appear.A survey of the scholarly literature concerning literary norms in the Japanese system and the status of translation within said system was performed and the following hypotheses were postulated: 1. Given sufficient knowledge of the norms of the Target Language's literary system and the status of translations within said system, the nature of differences between original and translation can be predicted. 2.

Är GPS-styrning lönsamt :

GPS is perhaps the future in agriculture. The next years will show it but the precision becomes only better and better and the number of users becomes only more and more. This work shows experiences from today's users and how the profitability can be improved on a farm with normal plant cultivation. The aim is to show how big the actual advantage can be to have a GPS and how good precision there is with the equipment. John Deere and Trimble are the big producers of GPS equipment to the agriculture.

Jordtäckta hus : Energiberäkningar och kostnadskalkyler på ett jordtäckt hus i Malmö

With rising energy prices and the threat of climate change, energy costs and energy savings havebecome a central and important part in building. Therefore it is interesting to explore different andnon-conventional methods of energy conservation. Building Earth sheltered houses is such a method.Earth provides good insulation and provides the ability to both reduce the total heating needs and toreduce the maximum power demand. The aim of this study was to construct a house in Malmö and seeif Earth sheltered houses can be a cost effective alternative for the construction of sustainable andenergy-efficient houses.Previous studies have shown that Earth sheltered houses have reduced their power requirement with upto 25% and their use of energy with 10%. Numerical calculations in Comsol Multiphysic 4.2, wasperformed on a house with different degrees of earth covering.
