En studie av två invänjnings-modeller i förskolan. : 3-dagars och två-veckors modellerna
I have made a research about two different methods for introducing small children to Nursery School/Kindergarten. I choose to do this as I have found very little about this in the literature we have studied during my education to become a pre-school teacher.This period in the life of very small children and their parents is a big change in their daily life. The more traditional way to start pre-school is to do it very gradually during two weeks, the two-week method. This means that the parents visit the pre-school together with their child for a very short time, about one hour the first day. After one week they leave their child with the staff for about an hour and at the end of that week they try to leave it full time (6-8 hours).
Kadmium i skånska vattendrag : en metodstudie i föroreningsmodellering
Modelling of pollutants is commonly used in research and at departments working with environmental issues. The need to use large amounts of data when modelling creates the opportunity for more generalised models with lower data demands. Aggregating functions into coarser elements is a sort of generalisation of actual features in nature.A development of a method and a modelling tool called ?KadmiumKalkylatorn? has been performed to model cadmium pollution in rivers in Skåne, Sweden. The water runoff has been multiplied with cadmium standard concentrations based on membership in landuse classes.
Det norska energideklarationssystemets konsekvenser för äldre byggnaders karaktärsbärande värden
Roughly 130 000 dwellings have been officially registered since Norway as of summer 2009 passed their bill ?Energimerkeforskriften? on energy performance certificates in buildings. The main objective is to decrease the total amount of national energy consumption by producing a methodology of calculation of the integrated energy performance of buildings as well as proposing cost effective measures to lower each building?s energy consumption. As the measures should not contravene nor be incompatible with the intended quality and character of the building, the ?Energimerkeforskriften? exempts buildings that due to their historical and cultural values are protected cultural heritage legislation. The current system offers a couple of professional certification alternatives, but when two online semi-automatic methods developed specifically for non-professionals are by far the most used, and since the methods of calculation primarily have focused on modern building materials and construction, the rest of the historical building stock stands literally unprotected by incorrect performance certificates and high-risk energy efficient measures. The objective of this thesis is to identify if the current Norwegian energy certificate system poses a threat to older buildings.
Analys av turbulensmodeller för CFD
This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.
Bostaden – sedd ur kvinnligt perspektiv
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.
Hydraulisk och termisk grundvattenmodellering av ett geoenergilager i Stockholmsåsen
Geothermal energy can be extracted from an aquifer, where the groundwater is used as heatexchange medium while heat and cold are stored in the surrounding material in the aquiferand to some extent in the groundwater. Application of aquifer storage for the use ofgeothermal energy is mainly used in large scale facilities and is limited to sites with suitableaquifers in the form of ridges, sandstone and limestone aquifers.Löwenströmska hospital in the municipality of Upplands Väsby, north of Stockholm, islocated nearby the northern part of the Stockholm esker. This means that it can be profitableand environmentally beneficial for the hospital to examine the possibilities of aquifer storagein the esker material next to its property.The purpose of this master thesis has been to investigate if geothermal energy storage with aseasonal storage of heat and cold can be applied within Löwenströmska hospital?s propertyarea using groundwater modeling. A hydraulic groundwater model was constructed inMODFLOW based on a simplified conceptual model of the groundwater system.
Lönsamhetskalkyl för produktion av gran på markavvattnad och askgödslad myrmark
In Sweden there are about 4 million hectares of bare peat (mire). This land has great potential to be transformed into productive forest land, provided drainage is carried out and, in some cases, even fertilization with ashes. Drainage of mires is necessary because the high groundwater table prevents trees from growing due to reduced oxygen availability. Some of the key nutrients that trees need to grow appear in too small quantities in mires, especially potassium (K) and phosphorus (P). Ash from the combustion of biomass contains these elements and is therefore suitable as a fertilizer.
Framgångsrik Implementation av Lean : Förbättrade möjligheter med implementationsmodell
Lean production is the name given to Toyota?s Production System (TPS) by the west. The continuous improvements of their operations through Lean has made Toyota into the largest car manufacturer in the world. This, in turn, has led to several studies regarding both Toyota and their system as to find ways to apply Lean in other organizations. Even so, over 90 percent of all companies fail to implement Lean.
Samlande vs. tillgängliggörande : En jämförelse mellan två förvärvsmodeller på akademiska bibliotek
The aim of this Master's thesis is to examine what effect two different models of acquisition have on user satisfaction with information resources at academic libraries. The two models examined are the traditional model where a subject specialist librarian makes the selection, and the user-governed model where the larger part of the selection is based on user requests. The scope is the libraries of Roskilde University, which employs the traditional acquisition model and Malmö University, which employs the user-governed. Both libraries have a user-oriented approach to acquisition. The study encompasses a close examination of the acquisition policy through document analysis and interviews with the librarians in charge of acquisitions at each university, as well as a user-satisfaction survey among the professors and senior teachers on two faculties at each university respectively.
Skapande av organisationskunskap i små, unga forskningsintensiva företag : En studie av tre företag i Uppsala
Because of among other things the globalization and a focus on core competencies knowledge has become very important for the companies of today, especially for research-intensive companies. The problem is that the companies become more sensitive to how knowledge is created and spread, that is, how organizational knowledge is created. Especially sensitive are companies who are small, young and research-intensive. The purpose with this thesis is to explore how organizational knowledge is created in small, young and research intensive companies.The theory is based on a five-phase model of organizational knowledge creation and four modes of knowledge conversion described by Nonaka and Takeuchi (1995). These concepts constitute the foundation of the analytical model used in the thesis.The study is carried out by qualitative, highly structured interviews with low standardization.
"Hur skall detta ske? Jag har ju aldrig haft någon man." : Hur feministiskt exegetisk litteratur bidragit till förståelsen av Luk 1:26-38 åren 1977-2012
This paper aims to explore the possibility of reading the Temple cleansing stories of John and Mark through Bruce J Malina?s honor/shame model, as E. Randolph Richards do. The analysis searches in John?s and Mark?s Temple cleansings for the presence of the notions of honor and shame, as Malina uses those concepts in his model.
Kapitaltäckningsregler med valfrihet : en kvalitativ studie om bankers frihet att välja beräkningsmetod för kapitalkravet
Purpose: The purpose of this study is to increase the understanding of how a bank?s features and internal factors have affected its choice of method in calculating the capital requirement.Theoretical and Empirical Method: The research strategy of this study has been of a qualitative nature with a deductive approach. The choice of method was depth interviews with respondents from a targeted sample of Swedish banks. These respondents were chosen based on the knowledge they possess as key employees in the capital requirement process and their involvement in choosing their banks? method for calculating the capital requirement.

Det stora cancerlarmet : En studie om riskrapportering i media
This essay is about the risks of reporting science through media. We have exemplified the problems with the alarm about acryl amide that came in 2002 through the diffusionist model. From the beginning it was a debate about how dangerous acryl amide is to us humans, but later on it developed to be a debate about whoever did wrong in the intermediation, because later on it came out that acryl amide maybe didn?t cause cancer at all and the scientists didn?t know how to prove if it did or didn?t. In our essay we have based our theories about how the diffiusionist model often is inadequate, with theorists as Stuart Allan, Anders Ekström and Dorothy Nelkin..
Introduktion till Kontinuitetsperspektivet
To explore greatly varied opinion between player and reviewer, in relation to new products in ongoing digital game series, an analytic perspective is suggested, that takes the entire game series into account, instead of analyzing games (who are part of a series) as individual productions. This is explored further by introducing a model to support this perspective, based on the game theories by Katie Salen and Eric Zimmerman, as well as Gordon Calleja. This model and chosen perspective is applied against three separate cases to see whether or not it can give insight into the approach of players (of continuing game series) and the differing opinions of players and reviewers..
