The aim of this study was to investigate how preschool teachers think about preschoolscience, what they consider science to be and how they deal with specific curricular objectivesrelated to science.Science is a part of our everyday life, it is a prerequisite for understanding everydayphenomena and how the world is working. Nevertheless it is often dropped in favour of othersubjects in Swedish preschools.The eight preschool teachers participating in this study are all working in the samemunicipality in the western part of Sweden with children aged 1- 5 years. The method used inthis study was interviews. The interviews were recorded to facilitate the transcriptions.The results show that preschool teachers find that science is an important subject that shouldbe introduced to the children early on in life. They also show that preschool teachers considerscience to have a preventive effect on the learning to the children, and it is needed for them tounderstand everyday processes and phenomena.

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.

The furniture retail industry in Sweden has gone trough large changes during the last decades. Today the industry is tough and in the maturity stage where few new companies enter, especially if they do not have a unique offer. The furniture companies have become larger and fewer, the changes have lead to difficulties for smaller and medium sized companies to grow and be profitable.Our purpose is to analyse, evaluate and compare three smaller companies in Stockholm with the intention to find what kind of marketing strategies they are using to survive on the Swedish market. First we interviewed the three companies to see what they do to survive on the market, then we asked 100 persons to fill in a questionnaire to see if they had the same opinion as the companies described.With help from theories we prepared questions which laid the foundation to the empirical part of the essay.The result from this study shows that the three companies differ from each other when it comes to using relationship marketing and placing the customer in the centre. All of them are aware of the importance of doing so, but because of different limits and possibilities they can not fully adjust everything to the customer.

Antalet kretskort som monteras i multikortssystem, till exempel telekommunikationssystem, ökar ständigt. Samtidigt som ytmonteringstekniken och packningstekniken blir allt bättre utvecklas även tillverkningsmetoderna för olika integrerade komponenter, vilket medför att varje kretskort rymmer allt fler integrerade komponenter. Detta gör att testning av integrerade komponenter och multikortsystem blir alltmer komplex. En förutsättning för att kunna genomföra effektiv testning är standarder. Standarder över hur testning ska genomföras medför att en komponent som uppfyller kraven från en standard är direkt utbytbar mot en komponent från en annan tillverkare som uppfyller kraven från samma standard.

As trading through advertisements increases, for example via advertisement websites such as Blocket, trading and contracting between individuals also increases. The contract law is the applicable legislation when individuals are trading between one another, because of the fact that individuals are to be considered equal against each another, and no consumer protection provisions are applicable. The contract law is not compelling, and general principles of contract law are therefore frequently applied within the legal area of contract law.Consistent declarations of intent shall have been delivered from both parties for a binding agreement to have been concluded. The declaration of intent, for example tender and acceptance are examples of a will to legally act. Other than tender and acceptance, the declaration of intent is usually difficult to establish and determine.In the event of the commencement of a negotiation stage between the parties, the declarations of intent are not deemed to be binding, but rather binding in the sense of a moral attachment for the parties.

In a world where digital media is becoming a greater part of people?s everyday and working lives it is plausible to assume that the upcoming generation of pupils expect the teaching media to adapt thereafter. It is this assumption of an increased demand that Natur & Kultur is hoping to be able to meet. This thesis has been a stage in the process of producing digital material in the subject of mathematics for high school students. Specifically the aims of this thesis have been to make a rough description of the largest competitive companies? products within the same market, explore and put together a brief theoretical foundation of contemporary research and produce concrete examples of ideas for digital applications.

Old hollow trees of oak contain a large amount of wood mould. Unfortunately, these trees have in the last century been greatly reduced in numbers. It has resulted in that species that depend on these habitats, saproxylic species, have become at risk to decrease in numbers or die out regionally. Previous studies have shown that the volume of wood mould is an important factor for occurrence and population size of saproxylic organisms. The aim of the present study was to examine how the volume of wood mould varies among ash (Fraxinus excelsior), lime (Tilia sp.), maple (Acer platanoides), aspen (Populus tremula) and oak (Quercus robur).

Infection with intestinal parasites can in many cases be the reason for decreased performance or production. The gastro-intestinal nematode, Ostertagia ostertagi, and the lungworm, Dictyocaulus viviparus, are the most pathogenic nematodes of cattle and severe infection can lead to death. They have both a direct lifecycle and on the pasture the parasites spread as freeliving worms. The parasites are mainly a problem for the first season grazers. They have not developed immunity against the parasites and are therefor more sensitive to parasite infections.

Construction projects are organized in different shapes and disturbances in the information flow in these processes can lead to problems, such as delays and/or a lower quality. Therefore, a well-functioning interaction between actors and a well thought out-communication at an early stage is of crucial importance. The main question is "How does the communication of decision and information flow in the building process and what barriers and opportunities can be observed?". This diploma work has been written with guidance from Bjerking AB and to answer this question, a collection of empirical data conducted via semi-structured interviews.

The purpose of this report was to study how the Swedish radio channel Sveriges Radio (SR) website changed over time. What are the differences between various media websites? How many people listen to normal and web-radio and what are the differences between the various services offered on the SR website?Reports from the BBC, Statistics Sweden, Mediavision and the Swedish National Post and Telecom Agency were compared. Several theoreticians have been studied, including Donald A Norman, Jonas Löwgren, Karen Holtzbratt, Jacob Nielsen and Geoffrey Moore.The method used by the author comprised a systematic mapping of statistics from webTrends, KiaIndex, SiteCensus, TNS Gallup/K2analys and reports from RUAB. The data studied have been collected from telephone interviews, postal surveys, internet panels, and from log files.

Complete tumour regression is the optimal outcome of cancer therapies. There are however types of tumours that naturally regress. Most of these are benign, dermatological and have an early onset in life. This literature study aims to elucidate the mechanisms behind spontaneous tumour regression. In Libechov Melanoblastoma-Bearing minipigs, an animal-model specifically bred to develop malignant melanoma, the tumours usually involute within three months.

This essay studies the relationship between politicians and municipal chief officers from the point of view of the bureaucracy and its role in democracy and the substance of the chief position. I conducted interviews and observations with politicians and senior officials from the local public administration in Bromölla. The roles of the chief officer and politicians have certain common characteristics which makes it difficult to separate them. Senior officials working full time in contrast to part time politicians give them an advantage in the political process. Budget cut backs both enhance the role of politicians and chief officers in the administrative organisation.

For any animator either working in stop-motion or 3D-animation the knowledge of the first animation techniques are most important. For it is based on these principles that animation today can create such vibrant characters. With the extreme development 3D-animation has undergone the last twenty years it is easy to lose track of the old ways. But with this thesis a hope to show that it is these old ways that will take animation to its next stage. My aim with this thesis is to find out if it is possible to identify the characteristic features of stop-motion and apply these onto 3D-animation with purpose to create a more expressive style of animation.

The great economic impact of startups on society has made these types of companies an increasingly popular subject for research. Though no single definition of the word startup currently exists, one could define it as a temporary organization in search of a scalable, repeatable, and profitable business model. Seen from a historic perspective, tech-startups in particular should be considered a new phenomenon and the topic is still relatively unexplored. This study investigates the structure in tech-startups during their first months of existence and compares it to the structure that prevails when the companies have recruited at least five additional employees. In addition, the study explains why these changes occur.
