Disinfection methods for drinking-water produced at the two water works of Stockholm Water Co are compared in this study. Three different nethods are compared; disinfection with chlorine gas, disinfection with sodium hypochlorite and disinfection with UV-light and monochloramine. The method used is Life cycle assessment, LCA. LCA is defined as the compilation and evaluation of the inputs, outputs and potential environmental impact of a product system shroughout its life cycle. The environmental burden is compared for the three different disinfection methods.

The aim of this thesis is to practice the theoretical methods that are concerned during the product development process of two new products. The theoretical concepts that embody the two products are created out of a product specification which is given by a commissioner with a private interest. The primary tasks of the design of the concepts are aimed on the products shape, which is to be created as a flexible structure by using silicon rubber as material.The storage box is a further development of the already known food storage box, or lunch box, which is common used in consumer kitchens. The main idea is to design a flexible product by using silicone rubber. It will able the storage box to be compressed when it is not used, be storage friendly and not consume more space than necessary in a storage compartment.

The aim of this inquiry was to investigate the most appropriate measures to reduce noise impacts from road traffic on the Nydala recreational area in Umeå municipality due to the planned re-routing of the E4 motorway to an existing road along this area. The sound environment is an important part in the experience when we are visiting recreational areas. Noise is not only disturbing; the liberty from unwanted sounds also allows us to perceive natural sounds that are a benefit for the cultural experience. Therefore it is important to take actions to protect this well used area from traffic noise. The reasonable options to avoid noise impact in this case are to lower the speed limit, using a noise reducing coating or use noise protection screens and walls.

Today?s political debate on environmental issues and environmental thinking, alongside the Swedish presidency of the EU and Climate Conferences shows that the environment is an important topic. Environment is important, not only in politics, but also for companies and the demand of environmental strategies and environmental reports has increased. This leads to an increased pressure on firms to begin to report on environmental concerns and to create active systems for environmental thinking.The aim of the present study is to examine why firms in the transport sector, mainly lorry transports, reports environmental aspects and what drives these companies to create these reports.Based on stakeholder and institutional theory we aim to examine to which extent stakeholders affects the environmental accounting and reporting. We also aim to explain how the organization is influenced to incorporate external and societal environmental procedures.

Delegation of assignments regarding the work environment is a complex topic that is difficult to illustrate. It is not explicit mentioned in the law and the established practice are ambiguous and vague. This has caused a lot of confusion, not only for private companies but also for executives within public administration.Metso paper Karlstad Inc. gave us the assignments to investigate their delegation system and to analyze the need of change before a planed readjustment. The purpose of this essay is therefore to investigate how the proposed delegation system is constructed and whether it fulfills the demands established by Swedish law.

Nuclear power production carries potential risks both for the environment and for the work force. Different safety measures are employed and they stem from local rules as well as from regulatory authorities. This work describes the development of a safety promoting tool at Forsmark Power Plant, one of Sweden?s three Nuclear power plants. We describe the development of a computer based system for Pre-Job Briefing and Post-Job Debriefing.

The decisions for investment are forward-looking and the base of a long-term strategy. The research within investment have focused on diverse formulas which are used in financial assessment, which also should be complemented with qualitative evaluation. Consequently, the focus should not only be on the execution of the formulas. Less time have been spent on research concerning what actually initiates the investment proposals and affects the decision-making. This will be highlighted in this essay.

Abstrakt I den här uppsatsen undersöks hur ett narrativ kan drivas inom digitala spel enbart med hjälp av spelmiljön. Syftet är att få förståelse för vad miljöberättande behärskar som en självständig form av berättande och vad författarna kan göra för att uppnå detta mål. För att undersöka problemområdet genomfördes en spelproduktion där metoder framtagna under undersökningens gång applicerades. Produktionen testades av utomstående studenter i medieteknik och resultaten sammanställdes med reflektioner kring vad som uppnåtts och de metoder som applicerats. Undersökningen beskriver arbetsprocessen och metoder och visar hur dessa kan driva ett narrativ med en spelmiljö. Abstract In this thesis examines how to drive a narrative in digital games using only the game environment.

Most of today?s concrete structures that are built on site are mainly constructed in a traditional fashion with a lot of artisanal operations. One step towards industrializing the in-situ construction of concrete is to use prefabricated reinforcement. Through this method there can be a lot of savings when each bar doesn?t have to be placed and fixed separately on site.

SammanfattningBåde grundskolans och gymnasieskolans kursplaner i Idrott och hälsa, framhäver friluftsliv som ett obligatoriskt moment i undervisningen. Samtidigt visar forskning att det bedrivs relativt lite friluftsliv i de svenska skolorna. Syftet med studien har därför varit, att utifrån de uppfattningar lärarna har om friluftsverksamheten i skolan, utveckla en djupare förståelse för betydelsen av friluftsliv och därmed skapa bättre förutsättningar i friluftsliv för dagens elever. Genom kvalitativa intervjuer med tre verksamma lärare, en idrottslärarutbildare samt en före detta idrottslärare, har jag kommit fram till flera värdefulla resultat. De viktigaste förutsättningarna för friluftslivets existens i skolan, är att den aktuella läraren har ett intresse för att driva en friluftsverksamhet, att det finns ett samarbete med andra lärare och att ledningen driver mot samma håll.

The aim of this project is to investigate the meeting between the city and the sea and tolook into how that could be developed and made use of. I want to find out how you can increase the availability of a specific place and make it more welcoming, I also want to bring life to an already existing space and create a central meeting place in the city. The purpose is to give form to an esplanade along a dock in the central parts of Kalmar. Starting with an analysis of this public place, I want to create a concept that is close to the existing context and communicates the contrasts or associations between for example: city and nature, artificial and natural and indoor and outdoor. The primary object of the project is to add a welcoming, public place to the city where you on an accessible way canfamiliarize yourself with the meeting between the city and the sea.
