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.

For centuries, Springs have played a significant role in our society as water supplies, reasons for where to settle down, and in folklore. There are different reasons why and where a spring forms, e.g. in what kind of soil it has its outflow. Geographic and geochemical surroundings have an influence on spring-water quality.For this project some of the Springs in the Lagga perish, Knivsta municipality, Sweden, were selected for a closer study. Water samples were collected from Springs for analysis.

This master thesis work was done by two students at Machine Design at KTH for Lesjöfors Stockholmsfjäder AB. The task was to develop a calculation program for gas Springs. The program is going to ease the selection of gas Springs for a given case of a lid that should be opened. The program is going to be used internal by sales people at Lesjöfors AB in Sweden and internationally. The program is therefore written in English.The program was developed in Microsoft Visual C# 2008 Express Edition.

In the middle of Australia there is a city called Alice Springs. The city has one of the highest amounts of daily sunshine hours and sun irradiation in the world. The Australian Government runs a project called Solar Cities, and Alice Springs is one of the participators. The main part of the goal with the Solar Cities project is to increase the amount of electricity generated by solar power and by doing that lower the impact on the environment. This thesis examines the possibilities for construction of a large scale solar power plant in Alice Springs. This is done to determine the potential of creating a more sustainable energy system in the city.

This master thesis takes its point of departure in the conflicting worldviews of modernism and post-modernism. As traditional segmentation theory Springs from the modernist worldview, this study aims to contribute to the understanding of the complexity regarding market segmentation for lifestyle brands in contemporary society, where the consumer is often claimed to be post-modern. The research was conducted in Malmö and Lund and involved 25 Converse users as respondents. The methods used in this thesis starts with observations as a sampling technique in order to locate the respondents. Short interviews and photo documentation followed.

When I began my studies at Gammelkroppa forest school I started to think about an appropriate thesis. There was much discussion about the wild grazing damage during that period. I was at that time a part of Boo property and helped at their great hunts. They had the dual uses of wildlife and forest. I decided that I want to study how big the wild grazing damages are and if we can reduce them.

The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat Springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air Springs.

This thesis has been performed at Scania CV AB Technical Centre in Södertälje and its aim hasbeen to study the causes and effects of deformations in the interface between the rear axlehousing ADA1100 and the central gear house R780 during operation. Design changes that wouldincrease the sealing capability of the studied interface are also suggested. Finite element (FE)and CAD software have been the primary tools in this study.Finite element (FE) simulations are used in the industry to predict and develop engineeringdesigns. The main motive for FE simulations has traditionally been to identify weak spots in thedesign, regarding high tensions and large deformations.The FE model is an aggregation of submodels and interface models that represents the rear axlehousing, suspension, central gear, central gear housing, wheels, bolts and weldings, and theirinteractions. The submodels have different material properties and they are connected withcontact interface models.Boundary conditions are defined on the bushings in front of the rear axle and on the air bellowsbehind the rear axle.

I work with and through glass and it´s from this field and tradition my work Springs from. I am interested in how we look at and judge different expressions. I have been taught what visual expressions and shapes that are being appreciated and accepted and how to create objects like that. It should be clean, smooth, simplistic, and utterly pleasing. I recognize these attributes from what is being thought of as beautiful and desirable concerning the body.

The aim of this Master of Science Thesis is to develop guidelines and improvementsuggestions of RiNOVA Traffic AB?s dynamic speed bump. The project started with athorough pre study of the design and its function to find out how passing vehiclesaffects the dynamic speed bump. The majority part of the pre study was to createnecessary mathematical models to explain the arisen forces and strains.The results of the mathematical models gave necessary information about the designregarding weaknesses and flaws. The most critical ones where those which interferedwith the design?s performance and reliability, and therefore needed to be corrected.These problems where more thorough analysed and discussed with experts before thefinal guidelines and improvement suggestions where developed.The parts of the design that had to be redesigned were the extension Springs and thebearing that enables the dynamic properties.

The last 1½ decade young people with intellectual disabilities have been a part of my life. My now 13 year old son and several pupils I have taught as a teacher in the compulsory school. Their future and what will affect their lives has always been interesting to me. How do I affect them, why do I do the things I do and think the way I think? This study Springs out of that curiosity.

When driving hard and cornering on a circuit good control of a car?s roll is desired, so the car reaches steady state quickly but yet in a controlled fashion. This control is mainly given by the combination of the cars Springs, shock absorbers and anti-roll bars.The aim of this report is to investigate, analyze and measure a Porsche Boxster?s turn in behaviour and roll dynamics as well as with the aid of simulation results give suggestions for improvement of the previous mentioned combination.Two different simulations were made, one based on a simpler model that was based on an evolved version of the bicycle model in Matlab and one was more advanced model in the simulation software rFactor. Measurements of the real car was made using a GPS-based measurement system.
