This thesis describes the design of a tipping trailer, from a company?s demands andrequests to complete manufacturing documentation. The design is developed for thecompany Abexor AB in Östersund that produces tipping trailers. The product issupposed to be used by Abexors customer to transport cargos of different kinds,such as gravel, stone, dirt, etc.The work commenced with a meeting at the company where demands were set.After that a pre-study was conducted to find out what traffic rules were required forthe trailer to be allowed to be driven on roads. Similar products were examined tosee how the trailer could be designed.

This thesis has been adjusted because some parts are classified, some sentences might have been changed. Electric bikes are a convenient mode of transport, a good choice when long distances or tough slopes can be an obstacle.The goal of the project was to create a prototype on a locking mechanism with an inductive charger for electric bikes.The idea behind the project was to develop a user-friendly locking mechanism, where the bikes would be charged inductively when they were locked. To implement the project facts about induction, battery charging and locking devices was needed to be acquired. Circuits for induction charging were created and a lock device was constructed. A microprocessor was used to control the entire system.A prototype was designed with a locking device and an inductive charger fixed in a bike rack.The entire project became very wide which resulted in that not all of the parts of the project could be completed.

Naturvårdsverket har enligt en genomförd kartläggning funnit drygt 80 000 potentielltförorenade områden i Sverige. På de potentiellt förorenade områdena har exempelvis olikatyper av industriell produktion ägt rum som kan medföra att området har förorenats. I MölndalsKråka, 500 meter öster om Mölndals centrum i Göteborg ligger en stor industrifastighet därindustriell produktion i form av tillverkning av olika kemiska produkter t.ex. i form avbindemedel till färgindustrin, har pågått sedan 1800-talet.

The forestry companies? operational planning process is these days dependent on reliable, efficient and user-friendly computer-based support systems. This study is an evaluation of Holmen Skog's current computer-based systems. The aim of this study is to: ? investigate the work pattern of the production managers when using the information system to plan the harvesting operation; ? investigate the efficiency and user friendliness of the information system with the different work patterns and to find the strengths, weaknesses and bottlenecks in the current system; ? find out if the type of object, the volume, the area of the harvesting object affects the time and work pattern; ? examine how this type of study is met by the employees and what factors that is critical to avoid feelings of intrusion. The conclusions of the study were: ? there is a large variation between the work patterns of the production managers and the time spend to perform the operational planning; ? the mainframe computer system used by Holmen Skog is clear, has short response times, is robust and conveys relevant information; ? the computer systems are however divided in many subsystems.

Since prehistoric time man has used wood to build their environment. The material?s availabilitycombined with its good mechanical properties has often made it the material of choice. Like allmaterials exposed to natures degradative processes the properties of wood decreases over time.Rot, UV radiation and attacks by insects and pests damage wood if not protected. Since we wantwhat we build to consist, optimizing our building materials durability is of great interest.Techniques and methods for increasing the endurance of wood have been developed in severaldifferent places and for a long time.

The aim of my thesis was to do a Life Cycle Assessment (LCA) of an average thread tap that is manufactured by Dormer Tools AB, and to create a practical model that the company can use in order to study other thread taps from an environmental perspective.The method of LCA is used to investigate the environmental effects of a product during its life cycle. This is a gate-to-grave analysis with focus on steel and thread tap manufacturing, coating procedure, use, waste management and transports. Three common coating types were compared separately. Steel manufacturing answers for the highest energy and raw material consumption under the life cycle of the thread tap. Its emissions contribute to global warming, acidification and eutrophication above others.

För att kunna bli pilot i kommersiell luftfart är första steget att utbilda sig. En pilotutbildning måste föregås av en medicinsk undersökning för att garantera en tillräckligt god fysisk hälsa hos den blivande piloten. Många utbildare kräver också att en person som vill utbilda sig till pilot genomgår en psykologisk lämplighetsprövning, i syfte att få en indikation på dennes personliga förutsättningar i övrigt för en lyckad utbildning och karriär inom pilotyrket. När utbildningen är genomförd är piloten redo för att se sig om efter arbete men den senaste tidens allmänna nedgång i flygbranschen har gjort det allt svårare för piloter att få anställning. Detta arbete har syftat till att ge en inblick i bakgrunden till den typ av lämplighetsprövning som genomförs inför utbildning, hur sådana prövningar värderas av arbetsgivare i branschen samt vad som i övrigt enligt arbetsgivare avgör om en pilot är aktuell för anställning..

Nowadays the majority of the thinnings made in Swedish forests are done by machines, harvesters and forwarders. The most common model in thinning with a harvester is strip-road operated thinning and stand-operated thinning with one intermediate passage between the strip-roads. This study is a time study with some quality follow ups on a strip-road operated thinning model, a stand-operated thinning model with one intermediate passage between the strip-roads and a stand-operated thinning model with two intermediate passages between the strip-roads. The machines in the study were a small harvester (Forestline MPM C90) and a medium sized forwarder (Timberjack 1110). The study was made in Litsnäset outside the city of Östersund in Sweden and was made during the autumn 2007. In a lodgepole pine stand six study units (0,6 ha) were thinned with the three different models, two study units per model.

Föreställ dig hur en modern stad  - vad skulle hända om man placerar en enorm glaskapsel över den? Hur lång tid skulle det ta innan livet däri skulle upphöra? Förmodlingen ganska snabbt. Med detta enkla tankeexperiment förstår vi hur beroende vi är av naturen - även i staden.     Vivarium är ett latinskt ord som betyder ?plats för liv?.

This project was conducted on behalf of the organization SABO (Swedish Association of Public Housing Companies). The aim of this project was to investigate which relevant environmental aspects and indicators there are for housing companies to present in their sustainability report. The project consists of three main goals: to decide if there is a need for common guidelines when conducting a sustainability report, determine appropriate environmental indicators and to create a simple model of how the companies can present them. This was done by a literature study, analysis of 13 sustainability reports and interviews with seven housing companies. The result of the project suggests that there is a need for common guidelines to, among other things, make it easier to make a comparison with other companies.

The forest property Fagerdal 2:10 was donated to the Swedish University of Agriculture in 1995 by Erik Rönnberg. The dominating species is Norwegian spruce (Picea Abies) and the average age is high due to selective cutting. The aim of this study has been to analyze how the forest on the property should be managed and demonstrate how a better estimated forest data affects the future management. The impact of the management on the carbon stock of the property was also examined. A forestry plan established in 2009 by Skogssällskapet was used as a basis for the analyses.
