Many of todays studies show that district heating is one of the betteralternatives as heating source because of its low environmental load.The energy source is often leftovers from other processes producing energy or waste, like garbage or chips.Electricity in combination with geothermal heating is another heating system that has increased sharply during the last years, and also this system decreases the discharges that have negative affectson the environment compared to several other heating methods.This report aims to, concentrated towards these two different heating systems, estimate the amounts of discharges they indirect cause and how the environment is affected.We have calculated the mean value for discharges of carbon dioxide, nitrogen oxide, sulphur oxide and dust generated from electrical power used in Sweden.Through interviews and research we have gained data for the same substances that district heating based on combustion of garbage and biofuel generates.We have also in cooperation with a housing company chosen a building we see representative for many of the new single-family houses built in Sweden today.Based on its shape and appearance we theoretically created three alternatives of the same house, each of them with climate screens different from each other.Together with the amounts of discharged environmental affecting substances, these houses were the base for our calculations and studies when investigating the different heating sources environmental effect.The results have thereafter been analyzed and discussed from different angles..

For an outdoor environment to function optimally as a playarea requires that it is flexible, that is, contains places and elements that give room for the imagination and for own interpetretations, and also that the children in some way can influence and change their surroundings. It is also important to have variety, both in the sense that the playground has a unique character that distinguishes it from other places, and that it allows many different games and activities. There should for example be room for both wild games of running and moving around where many children can participate, and calm corners to withdraw to for rest or quiet play. A good playground should surprise, challenge and encourage children to discover their surroundings. One way to achive this is to use plants and materials from nature, whose irregular forms and structures can become interesting elements to explore. Vegetation also gives sence-experiences of various kinds, materials like twigs and leafs to play with and a place to play house.

The project focus on combustion of softwood pellets and pellets in a 40 kW grate fire reactor at TEC-Lab. Dept Applied Physics and Electronics at Umeå University. Experiments were performed at four primary airs to fuel ratios (0.7 to 1.3), where aspects such as temperature profile, levels of gases (CO and NO), sintering-/-slagging and unburned fraction of the ashes were studied. Four different fuel loads were used for wood pellets (10, 20 and 30 kW) and one fuel load for straw (10 kW). Combustion of straw proved very difficult to ignite, and also led to other combustion-related technical problem such as slag formation due to the relatively low melting temperature-/-slag temperature of the straw.

The purpose of this study is to characterize the research in the field of Knowledge Organization, during the period of 1990-2002, focusing on the subject and the epistemology of these studies. The result shows that studies concerning representation, e.g. subjects such as classification, indexing and bibliographic description, are the most frequently researched areas throughout the period. Classification was more popular in the beginning of the period, but later bibliographic description, mostly with studies on metadata, became more visible, together with a growing interest in information retrieval. The theoretical discussions in the studies focused primarily on document analysis and the organization of digital documents.

This report aims at giving you as a reader a basic knowledge in measurement techniques used in the road/land construction and witch instrument and methods that is commonly used. It also tries to shed light on the problem with unfinished or incomplete blueprints, which cause additional work performed by the surveyor. This report is written in collaboration with PEAB Umeå whom has given insight in their work.The goal of this report is to examine what kind of work surveyors has to perform on blueprints delivered by a technical consultant. The reader of this report gets a run-through of the different theoretical measurement techniques used today and a short explanation of different measuring instruments used by surveyors in their day to day work. Computer programs used in the field of construction are briefly explained, and some of the most common file extensions used, for example dwg and Land-xml.The report concludes in a questionnaire that was sent out to surveyors employed by PEAB.

The purpose of my study is to examine how four teachers in a pre school believe they relates to and reasons about bilingualism. To be able to realize thisstudy, i proposed three issue following:How do the teachers in kindergarten relate to bilingualism?How do teachers in preschool reason around the work of bilingual children?What do teachers think about the educational environment in relation to language development?.

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.

Deliberate self-harm are a growing problem among young people in Sweden. It's not only the child that suffers from the behaviour, even the whole family. Parent´s need the right support from the healthcare staff for their own wellbeing, but also to be able to give good support for their child. Par-ent´s experiences are of importance for the nurse in the healthcare of the child and their families. The aim of this study was to describe parent´s experiences of living with a child with a deliberate self-harm behavior.

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 starting point for this master thesis was the product of the company "Humlegården", which allows its tenants in office buildings to follow their electricity consumption in real time, through their Smartphone's. The idea that resulted from that application is to investigate if it is possible to direct the tenants in office buildings to reduce their energy consumptions, but also to be satisfied with the indoor environment. This work addresses the factors which are the main energy consumers in office buildings. It addresses legal requirements and standards which are important to follow in order to achieve good thermal comfort in buildings. Some of them are physical climate factors like thermal environment, air quality and lightning.
