Potential för värmeåtervinning från mjölkkylanläggningar

The present climate discussion has made energy efficiency an interesting topic. Saving energy does not only help the climate but also saves money for the energy consumer. The purpose of this thesis was to examine the potential of heat recovering from milk cooling. Two milk farms, one with voluntary milking system, VMS, and the other with conventional milking system was used to measure interesting temperatures and electricity consumptions. The numbers were used both to do theoretical calculations and to construct a SIMULINK model. To calculate the potential for heat at milk farms theoretical calculations were made in MATLAB using a reference farm with different combinations of heat recovery and pre cooling. The farm was assumed to keep a dwelling house with the annual heat consumption 18165 kWh.

How streaming media can be used in commercial mass
distribution

Mass distribution with techniques as multicast and peer-to-peer are becoming increasingly important in the Internet. Today the distribution of sound and video over Internet, so called streaming media, is static due to the unicast method. This results in a linear increase of distribution costs and therefore no conditions for commercial scalability. This thesis describes why multicast may be the only scalable alternative for commercial mass distribution of streaming media over Internet. Mass distribution through peer-to-peer technology promises a lot but is fronting a couple of great challenges, for example asymmetric bandwidth, locality and legalization.

Environmental impact assessment of energy recovery from food waste in Singapore : comparing biogas production to incineration

As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.

Sociala medier - ett stöd för unga vuxna med cancer

The advancements of Internet have contributed to the expansion of social networks and new communities online where people are given an opportunity to get help and support. An important reason why people join these groups and organizations is to share their experiences, meet people in a similar situation and get support. Social media is nowadays an important part of our society. In this study, we will focus on investigating the interaction in closed communities online and blogs. The study aims to investigate whether social media and social networks online can be a support for young adults with cancer in the same way as physical meeting places.

Södra Thailand: Civila samhället - roten till våldet?

Using Varshney's theory about intra- and interethnic networks, this thesis examines how civil society in southern Thailand is built up.During 2004 the violence between Muslims and Buddhists rose in southern Thailand. The government tried to fight the insurgency using violent police and military forces, resulting in hundreds of deaths and part of reason why Thailand is loosing rank in Freedom House's democracy index. Varshney means that a civil society built up on intraethnic networks works favourable to violence between different ethnic groups. Sorting out and defining what is meant by ?ethnic? and ?civil society?, this thesis shows why to look at the insurgency in southern Thailand as an ethnic conflict surviving partly because of an intraethnic civil society.

Läsa, läsa, läsa ? skriva, skriva, skriva

The period of church awakening in Sweden during the first half of the nineteenth century, has had a great influence on the Swedish society. During that time certain persons are to be noticed. Peter Fjellstedt and Peter Wieselgren, priests in the Swedish Church, are among those who were of special importance. But even the British preacher George Scott and later the Swedish layman Carl-Olof Rosenius became aware of the importance of networking. They all felt a call from God to preach a message of redemption and restoration.

Scrum ? en fallstudie från lokala företags perspektiv

Through a case study, I wanted to find out what advantages and disadvantages local companies consider with scrum and what they think about its future. To find out what scrum is, I read the literature and scientific articles and then wrote surveys based on my thoughts. Further, I also wanted to find out if it?s possible to use scrum in a school environment and therefore I visited a high school class who used scrum in one of their projects. The result was good but could have been better as it requires more training of scrum to understand everything.

Riskbeteende och sociala nätverk : Spridningen av blodburna infektionssjukdomar

Blood-borne infectious diseases such as Human Immunodeficiency Virus (HIV)and Hepatitis C Virus (HCV) spread when the addicts share needles and injecting equipmentwithin contact networks. A quantitative cross-sectional study was conducted in Winnipeg,Canada in December 2003 - September 2004. Through a special questionnaire, respondentswere asked to answer questions about themselves and about their contacts, about relationshipsand how they shared syringes and other injection supplies. Blood tests were used to identifywhether they carried any blood-borne infectious diseases. We selected some variables from theoriginal data set.

Analys och beräkning av emissionsfaktorer för växthusgaser

An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.
