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.
Stäng dörren tack : En observationsstudie om dörröppningar på operationssal
Bakgrund: Flera studier beskriver vikten av att minimera dörröppningsfrekvensen på operationssalarna. Högre frekvens av dörröppningar leder till försämrad ventilation på operationssalen, vilket i sin tur kan leda till vårdrelaterade infektioner.Syfte: Syftet med denna studie var att på en operationsavdelning observera frekvensen av dörröppningar under pågående operation, varför och av vem de öppnades.Metod: Metoden var en kvantitativ deskriptiv observationsstudie med tvärsnittsdesign. Personalen på en operationsavdelning i Mellansverige observerades under pågående operationer. Observationerna utfördes sex vardagar i januari 2013 och valdes från operationsprogrammet.Resultat och slutsats: 22 observationstillfällen observerades, 11 från vardera konventionell respektive infektionskänslig kirurgi. Studien visade att dörröppningsfrekvensen var högre vid konventionell kirurgi jämfört med infektionskänslig.
Ventilation i häststall
Dagens sporthäst lever idag under människans ansvar i stallar. I stallarna förekommer luftföroreningar, den med störst påverkan på hästen är luftburna partiklar som huvudsakligen härrör från strö och stråfoder. Föroreningarna kan orsaka skada i respirationsorganen, vilket medför att hästen får en minskad prestationsförmåga och de kan leda till allvarlig sjukdom. För att bli av med föroreningarna i stallet behövs en väl fungerande ventilation, med tillräckligt flöde, som kontinuerligt kan byta ut luften i stallet.
Förståelsen för problematiken med partikulära föroreningar i stalluften är dålig, bland annat för att även starkt förorenad luft kan upplevas som frisk.
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.
Flödet av elektrisk och elektronisk apparatur i Sverige 1995 - 2011
The climate changes that are occuring in the world have resulted in that the EU callingfor a 20 % reduction in energy consumption to the year 2020, to reach that goal theEU want the public sector to go forth as a good example. Västfastigheter owns andmanage the hospital buildings in the Västra Götaland region. To be able to reducetheir energy usage Västfastigheter has hired several consulting firms to chart out theenergy consumption on each hospital building. The biggest energy savings potentialhave been calculated and what the cost will be to perform each action. The energyaudit have been completed and stand as the decision basis for Västfastigheter?s choiceon which action packages that should be implemented.
Energieffektivisering av befintlig bebyggelse med exempel från Göteborgsområdet
This thesis concerns to investigate renovations of existing buildings aiming at enabling energy efficiency, from a conservation and restoration perspective. This includes performing case studies of three projects in the Gothenburg area where renovations has been done and an analysis of directives raised by the EU and later implemented by the Swedish National Board of Housing, Building and Planning, Boverket. In addition to these, regulations enforced by the Swedish law, related to the topic, have been considered.The investigated projects in this case were the housing cooperative Välten in Brämaregården, the Solar Buildings in Järnbrott and Gårdsten as well as Katjas Gata 119 at Backa Röd. In order to measure and compare the results of these projects a comparison between the pre- and post-restoration energy consumption have been performed. To capture additional perspectives the grading system Operation Kungsörn has been applied.Regarding the comparison of energy consumption the renovation of Katjas Gata 119 was found preferable but showed in my view lacking attention to the cultural heritage of the area.
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.

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.
Inomhusklimat i ett statligt byggnadsminne
Statliga byggnadsminnen är byggnader som genom dess speciella kulturhistoriska värde är extra viktiga att bevara för framtiden. Att bevara, speciellt äldre byggnader, är inte alltid helt enkelt. En av utmaningarna i detta är att hålla ett lämpligt inomhusklimat i byggnaden för att förhindra en allt för snabb nedbrytningsprocess av material. Det finns tre lämpliga metoder för styrning av inomhusklimatet; Skyddsvärme, avfuktning samt styrd ventilation. Beroende på vad den byggnad eller det rum som studeras skall användas till och hur de unika förutsättningarna ser ut just där kan olika metoder vara olika lämpliga.
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.
Hur håller jag i 30 år? Vad krävs av mig som lärare?
AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power. ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant. As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol. Etanolens framtid vilar på bra lösningar för framställning. I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle. Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.
