Utveckling och tillämpning av modeller förkvantifiering av de ekonomiska konsekvensernaav ökad förbrukningsflexibilitet inom eldistribution

One step towards a more sustainable energy system is to create a more flexible electrical grid, where increased demand response among electricity consumers can play an important role. A distribution grid owner can encourage their customers to use electricity more evenly distributed during the day by introducing different types of grid fees such as time-differentiated power tariffs. In this master thesis, the theoretical economic impact of a flattened load profile for a distribution grid owner is investigated. Different factors that impact the distribution grid owner?s economy are identified and two are chosen to be quantified; losses in the grid and the fee to the feeding grid.

Vad kännetecknar en bra respektive mindre bra lärare? : En studie om gymnasieelevers syn på ledarskapskompetens i klassrummet.

The purpose of this project is to examine students' pespectives on quality in teaching. The characteristics that are described to denote a 'good' and 'less good' teachers are linked to ideas about types of corresponding leadership styles in the classroom. The report is based on surveys of students in Upplands-Bro high school outside Stockholm. In order to get better insight and further knowledge of the subject, the student accounts have been related to current discussions in the literature about good leadership and teaching quality.Following the methodology of grounded theory a pilot study was constructed to design the research instruments. In the pilot study I collected students' perceptions on quality-related categories in teaching and leadership which then formed a bases for a survey which was distributed to a larger student sample. The survey includes questions that relate to the middle order, which is based on three criteria that make up the characteristics of a 'good'/ 'less good' teacher and the leadership style that suits students descriptions of good teacher characteristics.The results of the study show that a good teacher should have subject knowledge, be good at writing and illustrating the curriculum on the whiteboard and explain and clarify their instruction through good communication.

Flaggskeppsbutiker som marknadsföringsstrategi. : -En undersökning ur ett kundperspektiv.

The purpose of this study was to examine customer attitudes towards flagship stores and how they perceive them. To ascertain this, and obtain answers to the research questions covering the study's main issues, we decided to turn to the customers who recently visited a flagship store.Our background theory is based upon literature from previous research done on the subject in the form of scientific articles and books. We present the theoretical concept that explains how flagship stores are used as a marketing tool and what impact they have on the new market. These will be helpful in answering our questions when we evaluate our results.!A theoretical framework, consisting of three value dimensions, was used as a support throughout the implementation of the study. These three values; hedonic, practical and social, should give us a better idea of what customers experience and what they value when they visit the flagship stores.!The method used in our investigation is of quantitative form, so that it can be feasible on a large crowd to thus contribute to a quantitative result.

Vems landskap ska förändras för att öka den biologiska mångfalden? : En studie av skillnaderna i odlingslandskapets konnektivitet med avseende på två skyddsvärda arter med olika preferenser

Organisms relevant for nature conservation dont follow administrative borders. Because of this there is a need for a landscape perspective within conservation and planning, and a need for the species of interest to have legal protection. Network analysis adapted for ecological purposes has grown to become a powerful tool for studying and communicating the relationships between species dispersion and access to habitat. In this study the following question is posed: How is the Osmoderma eremita and the Pernis apivorus dispersal possibilities in the small scale cultivated landscape of Borås affected by exploitation in respect to a) dispersal ability, b) habitat quality, c) position of habitat patches in a network? The analysis were based on municipal and regional nature conservation data, which in due to confidentiality is not accounted for in the report by maps, coordinates, etc.

Förekomst av ultra-fina partiklar och partiklar ?10µm vid diatermianvändning med mobilt rökutsug : Jämförelse av partikelnivåer centralt och perifert på operationssal

Flertalet studier har påvisat ett samband mellan koncentrationen av partiklar ? 10µm i luftföroreningar och cardiovaskulär- och pulmonell morbiditet och mortalitet. Vid resektion, koagulering/bränning med diatermipenna under operationer alstras rök. Denna rök innehåller bland annat mutagena och carcinogena partiklar i inhalerbar storlek (partiklar ? 10µm).Ett första syfte med denna studie var att kvantifiera den mängd ultra-fina partiklar (UFP) och partiklar ? 10µm som operationspersonal exponeras för i operationsrummet, vid användande av diatermi med mobilt rökutsug.
