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..

Soybean meal from South America is the most common protein feed used for animal production in Sweden. Production of soybean has negative effects on the environment and the transports from South America to Sweden causes considerable CO2 emissions. Therefore it is a growing interest in locally produced protein feed in Sweden. Protein feeds that are possible to grow in Sweden are rapeseed, peas, faba beans and lupins. Those are adapted to the Nordic climate and are perfect to grow in cereal rotations.

AbstractThe purpose of this study was to see if there is a connection between smolt length from Brattfors salmon cultivation and temperature. Climate changes are expected to give a higher temperature that could result in a longer growing season for the fish.Cultivated smolt is today bigger than it was before, it is also bigger than the wild salmon. The growth season of salmonids depend on the water temperature, salmonids need 6-80C to grow. Water temperature has been surveyd since the late 50´s in Brattfors. The result shows that it?s now considerable more days per year with higher temperature.

We investigated a retirement home, where we looked at whether there are differences, disagreements or conflicts between teams who work day and night shifts. Our purpose was to examine the Heads of Unit and the employees perspectives on their perceived work situation, cooperation difficulties and why they emerged. We chose the general systems theory as our theoretical basis, which gave us the opportunity to highlight different parts that can affect the working climate and the cooperation of the working groups. The study also highlights the importance of structure, common goals, reporting and dialogue meetings. To understand the perceived work situation, we used methodological triangulation, using quantitative and qualitative methods (surveys, semi-structured interviews).

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.

South Korea is one of the fastest growing economies of the world and experts claim that it?s headed towards the same direction as Japan. This doesn?t imply that the countries are similar to an extent where companies don?t have to consider the differences while entering the host market. This study was conducted for the purpose of giving a view of the business climate in the countries and thereby could help companies who see the countries as potential host markets.

When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.

There is an expression called ?grief of climate? that refers to feelings of powerlessness and heaviness related to the environmental problems of today. A feeling that every move we make has bad consequences for nature. This essay is an investigation of how art in general and jewellery art in particular can be a way of discussing and visualizing current environmental problems and the complex relationship between human and nature. I am discussing how artworks dealing with a dark and dystopian picture of the relation can be seen as the memento mori of our time.

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.

Foot rot is a severe claw disease which occurs among sheep and goats in most parts of the world, with outbreaks in hot and humid weather. It is a contagious bacterial infection caused by Dichelobacter nodosus in association with Fusobacterium necrophorum. Foot rot has a negative impact on both animal welfare and economy.This thesis presents how Australia, Nepal, Norway, Switzerland, Great Britain, Sweden and Uruguay handle foot rot. In the selection of countries the focus was on countries that have control- or eradication programs against foot rot. There are differences in the climate, animal husbandry practices, animal welfare and economic resources in the countries that are presented.

The climate at the labour-market in Sweden today means that students who have recently passed their examinations find it quite difficult to find work. The competetiveness calls for a strategy to find advantages in the employment process. The strategy explored in this thesis is called personal branding. We believe that by building a strong personal brand you can increase the possibilities to influence the decisions of those responsible for recruitments in our society. The question we ask ourselves in this essay is how to build a personal brand with the power to give students a competetive advantage in the employment process.

A severe profitability decline in sugar beet production in all of Europe is one of the consequences of the latest reform of the EU sugar regime. In south of Sweden, sugar beets is the crop that has been the most profitable by far for the last decade. The high profitability has contributed to the high rate of increase in the price of land and has restrained the structural change towards a more effective agriculture. Because of the reform, all sugar beet producers are facing diminishing income and must find ways to compensate this. The aim of this master thesis is to study how Swedish farmers adapt to the sugar beet reform. A questionnaire was sent to 354 randomly selected sugar beet producers.

This study was carried out at a company within the computer industry, a sector that is expanding and is facing scarcity of competent personnel. The purpose was to examine factors that are crucial for being an employer of choice. To get a profound picture of the employees' comprehension of their work situation, a qualitative method with semi-structured interviews with ten of the employees were conducted. To examine factors that are important for future employees a survey was created and handed out to fiftysix civil engineering students majoring in computer science. The results from the interviews showed that the organisation's culture was of great value to the employees.

The design of the building envelope affects the energy consumption of a building. As the energy requirements for new buildings are becoming more demanding, the performance of the building envelope must be improved. Energy efficiency and durability are important attributes to consider.This report includes investigations of the building envelope, moisture and passive solar energy. It is based on the analysis of two different buildings with different designs. These buildings stand as reference for two of the companies who are working on a new, climate smart, residential area in Uppsala, Sweden.Studies and analyses on energy consumption and moisture transportation were made.

Ethanol for automotive purposes is an issue much debated and researchers disagree about the benefits of bioethanol. Converting energy-rich crops into ethanol suitable as motor fuel is a complex process and continuous development and improvements of processes and material used are important steps in the work of developing environmental friendly fuels. Grain is usually preserved by drying which consumes a lot of energy. Alternative storage of high-moisture grain in airtight storage systems reduce the energy required to produce bioethanol and studies have also shown that ethanol yields are increased more than 10% in ethanol fermentations of moist grain compared to dry. Airtight storage is often not perfectly airtight so biocontrol agents are necessary in order to preserve the grain.
