During the last decades the housing sector has increased continuously, and housings and services accounted for 40 % of the energy usage in Sweden during 2011. The expansion in number of buildings in society has resulted in an increase in both energy usage and emissions of greenhouse gases. It is crucial to enable a sustainable development of society and as a result, the demand to reduce the emissions of carbon dioxide is a current question. In this study, the carbon dioxide emitted from the housing sector in Stockholm is estimated. The housing sector can be divided into different types of houses such as apartment blocks, single-family houses and holiday houses. By collecting information of the energy purchased in respective households, a computational model is generated that calculates the total emission of carbon dioxide.

One of the biggest changes which have affected businesses during the last ten years is the accelerating speed at which Internet technology and e-commerce has developed. If Internet earlier was used in the purpose to entertain it is now accepted as an essential business tool and companies are investing more of its resources in e-commerce activities. Everyone ?has to be on the net? today but that implies a challenge in matching e-solutions to the company?s business goals. It is necessary to have clear goals, carry out research and plan a strategy in order to operate an optimal e-commerce website for the company?s needs.The purpose with this dissertation was to see how well companies adjust to new demands in the rapidly changing e-environment.

This Bachelor thesis is a case study that explores the possibilities and complications to use social media in marketing purposes. The case involves a company that sells garments for men. The company, named Mouli, has decided to use social media as their marketing platform. The company makes an interesting case, since they are still quite new on the market and have all the possibilities to succeed.The purpose for the thesis is to examine Mouli?s use of marketing in social media and to evaluate what could be done to amend the communication.

This is a study, the purpose of which is to investigate how the construction company Sefab Bygg AB is able to increase its profitability and render a more efficient production process through logistic solutions. The study is made during one of Sefab´s present projects. The project includes sanitary renovation of 650 apartments in the co-operative Opalen in Norrköping.To find out whether changes of logistic routines are profitable or not, it?s necessary to evaluate the total cost of the changes. A total cost analysis is a mapping of all the costs for a particular material, on one hand for the present situation and on the other after the change.

In these days of globalization, with a higher level of openness and interaction over geographical, cultural and economical borders, the importance of the company?s intangible asset, its brand, is gaining importance as a differentiating factor. Building a strong brand and the emphasis on strategic brand management is something that before was given less attention in firms but today we can see a general increase in awareness and relative emphasis in the strategic work of companies.Countries as brands: Is it possible to consider a nation or a country as a brand the same way you consider a product? Well, looking in to the subject it seems to be a rather complex matter and there are many questions to be asked and answer. Nations around the globe are indeed marketing and positioning themselves for several purposes.

Many studies have shown that unethical acting can affect the share price of the company negatively. However, this is not always the case. The aim of this thesis is therefore to examine what it is that can cause the share price to be affected negatively by unethical acting exposed in media. This qualitative study is primarily based on interviews with institutional investors, but also with economic journalists and investor relations managers. Our conclusion is that there are three main reasons why the share price can be affected by unethical acting, namely economic consequences, the management's behaviour and psychological factors.

Emissions of insufficiently treated wastewater, mainly blackwater (i.e. wastewater from toilets), contributes to the eutrophication of lakes and seas. At the same time, blackwater is a fraction with a low content of heavy metals and, after sanitization, it can recirculate plant nutrients to arable land using the liquid composting treatment method. Liquid composting means that organic material is degraded under aerobic conditions. For sanitization, the blackwater needs to be treated together with energy-rich complementary material.

The Rya power plant in Borås produces district heating, district cooling and electricity. The plant is owned by Borås Energi och Miljö AB and is run by Dalkia Facility Management AB.In order to get the best heat exchange from the district hot water a pair of twin pumps and a turbine circuit pump are used as return pumps. Turbine circuit pumps are used to increase the pressure through the heat exchangers at the power plant. The pumps are in use when the flow is over 2 000 m3 h-1 and during the summer when re-cooling is used to improve the effectivens of the heat boilers.Since the pumps, that are parallel connected, rotating at a fixed rate per minute, the pressure is regulated with regulating valves. This report shows that during the 4,300 hours that the pumps where in use, energy corresponding to 590 MWh was wasted.

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.

Stump biomass is energy rich and stump harvesting for use as fuel become more and more interesting in Sweden. Swedish Forest Agency (2009) has estimated that stump harvesting in Sweden would respond to an annual energy supply of 57 TWh/year. However, stump has not been recognized as a bioenergy resource in Sweden. Suitable methods for pre-treatment of stump are probably of great importance to make it accepted as fuel. It is therefore rewarding to carry out an investigation in this area for stump. This report represents results from a diploma project, which was aimed to develop a fixed bed reactor for experimental study of biomass torrefaction, followed by TG analysis and kinetic modelling employing Ozawa method and different kinetic models including one-step and three-pseudo-component models.

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.

This essay is part of a project between Södertörn University College and Stockholm Academic Forum. The focus of the project is gender equality in small- and medium sized companies. I have worked with a construction company called Activa . The majority of the employees at the company were male and I was interested in the consequences of gender construction in such an environment. I think that the basic condition for equality work is an understanding of gender and the male norm.
