Bentiska evertebraters förekomst i källor på Öland

Abstract The benthic macroinvertebrate fauna of 22 natural springs on Öland was sampled, by using a time-standarized kick/sweep sampling technique, in the end of September and early October. The aim was to determine the number of species and their abundances in the macroinvertebrate communities in springs and how/why these may change between different springs. Likewise there was a purpose to investigate possible differences between springs considering the proportions of the number of species and the abundances of the five functional feeding groups; shredders, collectors, filter-feeders, scrapers and predators. There was also an aim to investigate if the distances betweeen springs had any influence on similarity between the communities of benthic macroinvertebrates of the springs. Analysis from the springs collected material showed several interesting patterns in the number of species and their abundances when compared between springs devided into groups depending on their environmental factors such as depth and pH.

Livselixir : En studie om Harry Potter, moralisk utveckling, livsfrågor och religionsundervisning

This bachelor's thesis examines three books in the Harry Potter series, Harry Potter and the Philosopher's Stone, Harry Potter and the Order of the Phoenix and Harry Potter and the Deathly Hallows. The aim is to increase understanding for what Harry Potter could contribute in terms of morality in religious studies, and how the story about Harry Potter, as a popular literary phenomenon, can be helpful for this. Lawrence Kohlberg's theory of moral development is central to this essay.I have used an hermeneutic method for the analysis of the Harry Potter books. The result shows that the main character, Harry Potter, can be seen as kind of a role model when it comes to moral development. Pupils may benefit by reading this book series because it can open their eyes to life questions and moral values.

Utveckling av barnvagn

After contacting the company Elite Group Sverige AB, who sells strollers under the brand Crescent Baby, it was determined that the project group were to develop a three wheeled stroller which was going to be Crescents first own developed stroller. Only the frame of the stroller was considered within the demarcation of this project however care was taken to the placement of the carry-cot and the wheels etc. Crescent Baby wished for the frame would be smaller than the competitor Urban Jungle, that the frame would have at least three unique selling points and that the number of unique parts was to be minimized. The work began with information seeking regarding strollers, competitors, independent tests, European standards and consumer interviews. After that a number of concepts were developed and past to Crescent.

På resa genom turistbroschyrernas Småland

The purpose of this study is to analyze how places can be marketed through tourism brochures. The study is based on a discourse analysis and texts and pictures from three brochures, which come from the region of Småland in Sweden, have been analyzed. The first brochure is from Visit Småland, the second from Vetlanda municipality and the third from Värnamo municipality. With the rise of globalization one of the consequences has been the increased opportunity for tourists to visit places all over the world, which also resulted in a greater competition between places than before. One reaction to this has been the increased marketing of each place unique characteristics in the tourist brochures.

Beslutsfattande och uppmärksamhet : Heuristikers påverkan på kognitiva resurser inom konsumentpsykologi

Every day we make numerous decisions. Some are better than others. Intuitive decisions usually results in less good decisions when we do not reason about our choices. Research has been interested about the process that is behind how we make good decisions. Decisions we face every day, such as when we shop, determined using various mental shortcuts that we use unconsciously.

Undersökning av energibesparande metoder för multiplikator

In this thesis a number of energy saving methods for a multiplier on algorithmic level are investigated. For the investigation a multiplier is constructed in VHDL, after which the circuit's performance is investigated. A number of techniques for reduced power consumption are introduced in the circuit and are then evaluated. The conclusions are that all investigated methods, pipelining, interleaving and voltage scaling, should be maximally made use of in order to minimize the power consumption..

Kan gullstånds hålla stånd?- återinventering av Senecio paludosus i Kristianstad Vattenrike 2012

Botanist Kjell-Arne Olsson inventoried the plant fen ragwort Senecio paludosus 1983 in Scania andfound a big number of locations within Biosphere Reserve Kristianstad Vattenrike. In 2012, a reinventoryof the 1983 survey was carried out to study whether there has been any change in the fenragwort population in Kristianstad Vattenrike since the last inventory. The results show that therehas been no overall change in the number of fen ragwort in Kristianstad Vattenrike, on certainpremises they have increased in number while in others they have fallen. However, the inventoryshows that almost half of the locations with fen ragwort have disappeared during the same period.The main reason for this is that fen ragwort did not manage to competitive with other vegetation,taking in consideration this has been smaller premises with young plants. In addition to competitionother factors such as prolonged high water, grazing and caterpillars from Tyria jacobaeaecontributed to the decrease.

Aktivering av trafiksäkerhetskameror : En studie av kameraaktiveringens effekter på fordonshastigheter i Sverige

During 2006 an estimated number of 150 persons are supposed to have been killed in road accidents caused by speed limit violations. Through Automatic traffic security control (ATK) the Swedish road administration (Vägverket) is working towards lowering the number of speed related accidents. By placing the speed cameras on roads they've managed to lower the average speed at those places. The enlargement of the number of speed cameras is based upon knowledge about for example how high the risk is for speed related accidents on the roads. The speed cameras always measure the speed in which every vehicle passes, but aren't constantly activated to register speed violations.

Genom statistisk analys utvärdera geometriska parametrars påverkan på ett XPI- cylinderhuvuds snurrtal

This Master Thesis is a product development project that has been carried out in cooperation with Scania CV AB. The purpose has been to find the relationship between geometric parameters and the swirl number for an XPI- cylinder head in order to improve the design specification.The increased focus on environmental issues from society leads to tighter emission legislations for the truck manufactures. In order to drive the development forward considerable resources are spent on research and development on diesel engines and its combustion process. The inlet air has a significant impact on the formation of emissions and the flow that is desired is called swirl. Swirl is achieved by making the air rotate around the vertical axis of the cylinder.Earlier cylinder heads that has been developed at Scania CV AB have shown clear relationships between geometric parameters of the cylinder head and the swirl number.

Can increased activity recorded with help of activity monitoring sensor indicate an upcoming calving?

The purpose of this study was to find out if motion movements, e.g. number of lying bouts and lying time with a registered activity monitoring sensor can detect an impending calving and thereby be used as a measure and an indicator for an upcoming calving. For this, automatically step sensors were used and were attached to one of the cows? hind leg. The sensor registered the individual step and movement activity of the cow.

Patent och företags storlek - finns det en tröskel till inträde?

Several studies have investigated the relationship between different measures of innovative activity, such as patent statistics and R&D expenditures and some have looked deeper into the differences between large and small firms regarding number of patents issued per employee or per R&D dollar. In this paper, the objective is to find out if there are any indications of a barrier to entry (due to economical factors, lack of knowledge etc) for small firms to get into the field of patent handling. The approach is to first set up a hypothesis based on some simple assumptions about how firms would make decisions about whether to apply for a patent or not and thereafter use econometric methods in an empirical investigation. The data used for this study are figures on number of employees, number of patents granted and R&D expenditures for the Swedish firms in the pulp and paper industry. The main conclusion is that, based on the analysis of the data from this rather limited group of firms, no such barrier can be seen..

Förändringar i skogsbranschens organisation på 1990-talet : antalet tjänster, kompetens och utbildningsinsatser

In 1993 Sweden introduced a new Forest policy, with a larger freedom of action for the forest owners, but in the same time the forest owners are expected to take greater consideration of the forests and the environment, that is required by the law. This is necessary to be able to obtain the goals of the new policy. Therefore the demand for competence and guidance is larger than before. At the same period of time organisations where slimmed and trimmed during a economic recession and the question is how this has affected the number of employees on different levels in the organisations, the competence of the employees and their internal education and if these changes affects the possibility of implementing the forest policy. This study contains three points in time where measures were made, 1990, 1995 and 2000.

Förebyggande Brandskydd

The number of residential fires has not declined sufficiently since the smoke alarm entranced the Swedish homes, fires lead to devastating consequences in which possessions, homes and worst of all human lives are at stake. Every year, about 80 people get killed and more than 500 get´s injured in residential fires, often due to lack of safety equipment. The number of fires caused by electrical appliances has risen and taken over a period of ten years the fire caused by a forgotten stove has increased by 70 percent. Preventing the risk that a fire would start on the stove would saves money, worry and most importantly, lives..
