Ödesstund för Europa : Om de geopolitiska konsekvenserna av Europas beroende av rysk energi
This is a tale about energy and power. It describes the geographer Halford Mackinder?s geopolitical theories and compares them with current views outlined by Zbigniew Brzezinski and Michael T Klare, among others. With a critical approach it also provides a historical account of a Europe that stands in front of an energy struggle so severe that the current world order seems destined to fall. Oil and natural gas, has since the beginning of the 20th century, been used as a geopolitical tool in order to create dependence, control and even sometimes overthrow empires.
Effektiv projektledning med standardverktyg, Går det? : MBA-uppsats med inriktning elektroniska affärer
AimThis paper has come about because of the author's own experience as a project manager at FMV. In various projects, I have wondered if there is a link between the programs and processes that I have to use in my daily work. Are these programs effective for managing projects and follow-up.MethodIn order to examine whether it is efficiently using standard software, I have asked a number of projects manager at FMV to respond to a questionnaire, the method is qualitative.AbstractEfficient project management will require a set of tools for planning, monitoring and evaluating. Often there is a demand for a comprehensive range of enterprise software applications and business solutions combined to one business solution. A relevant question is if it is possible to use standard software, i.e.
Fuktproblem i sydöstra Asien
The author has, with the help of AK Consultancy Indoor Air AB, formed a series of questions regarding moisture problems in buildings and how these are handled in extreme climates with high temperatures and a high relative humidity. Furthermore to analyse and indentify key material that makes a construction safe against moisture problems. Ventilation, AC and the choice of materials have in a later stage of the thesis been investigated to enhance the knowledge of moisture protection. The research for this report includes measurements on existing buildings, calculation models on the building envelope for analyses and the ingoing materials of the envelope. The health aspect of moisture problems related to ?sick building syndrome? has been included and interviews have been conducted to gather relevant information.A study of the American system, ASHRAE, American Society of Heating, Refrigeration and Air Conditioning Engineers and the standards used in Singapore has been made to highlight the difference.
Metabolit- och hormonnivåer som tidiga markörer för fruktsamhet och produktionsstörningar hos mjölkkor
During the last decades the fertility of dairy cows has declined in the same rate as the milk yield has increased. This is a result of the negative genetic correlation between milk yield and fertility, failure to show estrous signs and metabolic problems in the cow. The purpose of this review was to investigate the function of metabolites and hormones as markers for disturbances in fertility, health and production in the dairy cow. There are several metabolites that are suggested to indicate the cow?s energy balance.
Grön asfalt och NCC : rätt tillväxtstrategi för en asfaltproducent?
NCC ROADS Sweden east is a part of the NCC Corporation. The company mainly
produces aggregates, asphalt and concrete. They have taken the environmental issues
seriously and been working with that since the middle of the nineties. When
manufacturing asphalt large a quantity of fossil energy is needed. The company is now
about to make further progresses by manufacturing environmental friendly asphalt
(?green asphalt?) with using bio-energy.
Biogaspotentialen av matavfall sorterat ur hushållsavfall.
To achieve the Government's milestones for 2018, which means that 50 % of food waste shall be separated from household waste and undergo biological treatment (composting or anaerobic digestion). Hultsfred, Högsby and Vimmerby are three adjacent municipalities of Kalmar, county Småland. During 2012 and 2013 analyzes were performed on their household waste to determine its composition. The household waste is currently collected in one fraction. The work, examines how much food waste the household waste contains. From the amount of food waste, the biogas potential is examined - how much food waste biogas generates and how much energy it corresponds to. Food waste is broken down by microorganisms under anaerobic conditions (anaerobic digestion) in a biogas plant.
Den rebelliske aktivisten : En fallstudie av WeAretheSuperlativeConspiracys användning av Weactivists i varumärkesbyggande syfte
This study has a focus on brand building and brand identity. The overall idea of the study is to examine the Swedish clothing company WeAretheSuperlativeConspiracys brand building tactics and activities. WeAretheSuperlativeConspiracys, or WeSC, is a company that produces and sells streetfashion in over 20 countries and has over 1600 distributors. The company has in the recent years grown to become one of the largest in its segment. The interesting factor in WeSC´s brand building activities is the use of Weactivists.
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.
Metod för beslutsstöd vid formulering och uppföljning av en kommuns klimatmål : Fallstudie Uppsalakommun
The purpose of this study is to create a method that can be used to produce decision supportdata for the climate goals of a municipality. The method should be able to demonstrate the potential for reducing energy use and greenhouse gas emissions for measures aimed at the stationary energy system in the municipality. It will be used to make long term projections of energy use and greenhouse gas emissions in order to be able to demonstrate the ability to reach climate goals. The aim was also to test the method's applicability by using the municipality of Uppsala and the Uppsala climate protocol project in a case study. Uppsala climate protocol is a project consisting of participants from business, government and organizations that voluntarily want to commit to reducing their carbon footprint by reducing their energy use and thus work to achieve the municipality's overall climate goal.
En studie av olika ekonomiska modeller för mångbruk baserad på vindkraft
Today produces the wind power 2,5 TWh (TWh = terawatt hours) of Sweden?s total energy input of around 620 TWh. The Parliament has adopted a national planning objective where the wind-based electricity production will increase to 30 TWh in 2020. This requires that landowners will leas there land for wind power to wind energy companies. Such land leasing means that the landowner's business is considered to be a multiple-use.
Delårsrapporter - osäkerheter och bedömningar i praktiken
certain building or environment can get a protection as a notable building if it contains certainvalues. These values are established by a certain category of people from the cultural sector.These people use established criterions to define the cultural value of the object. The objects canbe evaluated differently depending on who has done the evaluation. The people who protect thecultural environment and choose which buildings that are to be defining as notable buildingsoften uses a special model to characterise the different cultural values. This model is produced bya man called Axel Unnerbäck.
Fuktrisker i kallvindsutrymmen - problem och förbättringsmetoder
This report has a dual focus. The first goal was to increase the knowledge of how the use of electricity in a residential building is distributed. Electricity in residential buildings is used for lighting in common areas, elevators, pumps and many other appliances. The electricity used for these different parts is to a great extent unknown. A few studies have been carried out and the result of these is referred to in this report.By means of measurements and approximations the use of electricity for various appliances became known.

Konvertering från luft till vätskekylning av elektronik
A Swedish electronics company wants to make the cooling of one of their electronic components more efficient. They propose that a retrofit liquid cooler is the way to achieve this goal. The current air cooling has high energy cost due to the high amount of power needed to power fans and heat exchangers. Using high volumes of air for cooling also leads to noise pollution. The conversion from air to liquid cooling would possibly make the operation of the electronics more cost efficient and less noisy.The purpose of this project is to theoretically evaluate different concepts of drawing the heat generated by the electronic component in to a fluid, using numerical calculations in Matlab and FEM simulations in ANSYS.
Rehabiliteringsträdgården : hur människan påverkas och utformningens betydelse
In today?s hectic society more and more people experience stress and our lifestyle gives us a very limited chance to recover. For some it sometimes goes that far that they get burnt-out, they have pushed themselves to the ultimate limit. There are different methods and treatments to recover but one very efficient treatment is to spend time in a rehabilitation garden. There the patients get treated by therapeutics that uses the garden as the main tool.The fact that gardens and parks have a positive effect on humans have been used by people for a long time but it?s not until recently that the research has taken speed.
