This report discusses the development of lessons based on laborations for middle and high school.The purpose of the project was to research the possibility to affect students' attitude towards physicsthrough well-planned stimulating lessons. The lessons were based on the Light and Lasers OutreachKit, a teaching package made by the organisation Laser Classroom, and have been adapted for physicsin middle and high school. The lessons were developed on a pedagogical and didactical ground andwere improved with surveys and peer and self assessment. The lessons were based on laser light and itsproperties. One lesson covered the topic of single-slit diffraction, while the other treated geometricaloptics.

The purpose of this thesis is to analyze the regulatory power, efficiency and impact of export control on Swedish arms export from the 1980s onwards, linked to the delegation of authority of permit license to the Inspectorate of Strategic Products in 1997. An increase in the administrative sector, based on a collective decision making process and established criteria and guidelines, aimed to strengthen the control of arms export to non-democratic and problematic states. In short, the aim of the study is to investigate and analyze whether there was a decrease in the arms export to problematic states or not. On one hand, it is reasonable to assume that the introduction of the new regulation entailed a more strict arms export policy. However, previous research has showed that regulations are sometimes not effective since incentives to breach these may be present.The study begins by examining the Swedish case and situation in terms of arms manufacturing and export, as well as the delegation of authority and legislation applied to the field over time.

The persecution of the Rohingya Muslim minority population in southwestern Burma has come to the fore in recent years. The aim of this study is to first analyse the degree and respects of biopolitical control in the case of political oppression. Secondly, the aim is to compare the similarities and differences when it comes to the causes, mechanisms and expressions of the two theoretical starting points in the case.Giorgio Agamben´s biopolitical theory, which tries to reconnect state control over life and death with modernity, forms the basis of the analysis. Will Kymlicka´s liberal theory on minority rights serves as a theoretical comparison tool. Methodological starting points to the specific bilateral purpose will be both of the textual and discursive analytical tradition.

Denna undersökning belyste sambanden mellan arbetstrivsel i relation till Locus of Control, chefens tillgänglighet för arbetstagaren och uppmuntran från chefen. Tidigare undersökningar har visat att det finns en positiv korrelation mellan intern Locus of Control och arbetstrivsel. Forskning har även visat att det finns samband mellan olika typer av ledarskap och arbetstrivsel men lite forskning är gjord för att undersöka vilket samband det finns mellan chefens tillgänglighet för arbetstagaren och arbetstrivseln. Av de 47 personer som deltog i undersökningen var alla kvinnor, vilka alla arbetade inom Vård och Omsorg men på två olika arbetsplatser där på den ena arbetsplatsen hade kontinuitet bland chefer och på den andra hade de varit olika chefer under samma period. Studien visade att det finns ett signifikant samband mellan arbetstrivsel och chefens tillgänglighet, LOC, och uppmuntrande ledarskap, däremot fanns det inte någon signifikant skillnad i arbetstrivseln mellan de båda arbetsplatserna.

Gerbera jamesonii is a plant with a large amount of pollen and various flower colours and a favourite host plant for Frankliniella occidentalis. The best growing temperature for gerbera is approximately 20°C. Frankliniella occidentalis or the Western Flower Thrips is a small insect that has become an important pest in greenhouse cultivation all over the world. The high temperatures in the greenhouse are favourable for F. occidentalis.

Mobiltelefoni och SMS (textmeddelanden) är ett intresseområde på frammarsch. Avsikten med studien var att undersöka om personlighetsegenskaper som självkänsla och locus of control har någon inverkan på vilket sätt människor använder sina mobiltelefoner. Tidigare studier har indikerat att de som föredrar textmeddelanden har lägre självkänsla än de som föredrar röstkommunikation. Ett internetbaserat frågeformulär användes för att undersöka mobiltelefonanvändningen hos studenter vid en högskola i södra Sverige, och då speciellt undersöka tal/text preferensen i relation till ålder, kön och personliga egenskaper. Överlag visade gruppen av studenter (n= 116) en preferens mot att tala (M = 4.5 med text och tala som ytterligheter på en femgradig skala).

Problem: In society of today corporate competence is an important factor for survivor and development. IT is developing rapidly and can not be ignored by companies. Then need for people with IT-competence is conquent increasing. A survey of corporate IT-competence is therefore of interest for companies as well as for local authorities. To determine the IT competence within an organisation, this competence has to be measurable.

The aim of this thesis is to examine how different kinds of information seekers are evaluating information quality in the information flow online. To address the problem stated, qualitative interviews were carried out with a librarian as a reference person and a group consisting of journalists and scientists. The result of the study implies that the reference person is well aware of the strategies employed by her in the search process. However, the respondents are not aware of the strategies they are actually using. An explanation is the respondents lack of education in information seeking.

The aim of the study is twofold, to generate a sensory profile of Swedish wine today and to investigate the opinion of both wine producers and wine experts on viticulture in Sweden and wine from grapes grown in Sweden, achieved through a contextual analysis comprising a literature study and interviews with wine producers in Sweden and Denmark and wine experts from Sweden and Germany, and a sensory analysis at the company Ipsos. ?Mixed methods? was the chosen research strategy as the semi-structured interviews gave qualitative results and the sensory analysis would give quantitative results displayed as spider charts. There is a lack of studies investigating how the Swedish wine is perceived by consumers and consumers might be unaware that the Swedish wine, established through ?trial and error?, is increasing in quality every season, creating a need to display the sensory profile of Swedish wine to strengthening the perception of Swedish white wine. This study shows that the Swedish white wine today is a wine with a fresh, citrusy and flowery aroma and a fresh, citrusy and green apple taste, however, a sensory analysis cannot show if the attributes are those that are desired by the customer, a consumer test is necessary to conclude that. Trends point towards locally produced products, one reason why Swedish wine has great potential, yet the future needs to be secured through job opportunities and education. Creating an approval system for Swedish wine is suggested as a future improvement, it is a common procedure in most wine regions.

Floor surface in pig facilities can have an impact on animal welfare and pig health, as it can cause the pig physical damage and thereby increased risk of infectious diseases and lameness. The development of pig housing systems has resulted in a decreased use of bedding. It seems hard to find the optimal floor in farrowing pens, as it must suit both the sow and piglets. The floor friction needs to be adequate to avoid slips and at the same time should the floor be non-abrasive. Abrasions and lesions caused by the floor are not only causing the animal suffering, but are also negative from an economical aspect.

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.

As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.

LKABs infrastrukturavdelning är en sekundärproduktion och en stödjande funktion till primärproduktionen vilket gör att avdelningen utför många olika aktiviteter och är svårstyrd. Syftet med denna uppsats är att studera den formella och informella styrningen och dess styreffekter på LKABs infrastrukturavdelning med utgångspunkt i Simons Levers of Control Vid formell styrning såsom Simons levers of control, styrs företaget genom dokumenterade värderingar, gränser, interaktivt arbete och uppföljning. Informell styrning kan vara företagets kultur, ledarstilar, regler och normer som inte är dokumenterade utan informella. Både formell och informell styrning påverka en individs beteende det är därför viktigt att de som skapar formella styrsystem tar hänsyn till de informella faktorerna och att den informella styrningen är i linje med den formella styrningen och att det finns en balans mellan dessa på företaget för att nå önskade styreffekter. I denna studie har en kvalitativ forskningsmetod tillämpats med influenser av aktörssynsättet.
