The aim of the thesis was to investigate energy consumption and carbon dioxide emissions from an advertisement broadcasted on the radio or the television or distributed through press. The object was to calculate the amount of carbon dioxide emissions per individual receiver of an advertisement in Sweden. There was no room for a deeper investigation into editorial work within the framework of the thesis. Consequently, main focus of the radio and television study was on broadcasting itself and the components involved. Focus for the press study was on paper production, printing and distribution. Production and discarding of media equipment was not taken into account.

The idea with this study is to examine if there are a connection between how optimistic people are in relation to how stressed they feel. The result from the survey is based on materials from a questionnaire has been sent to fifty persons of varying age and sexes. The questionnaire has also been sent to students from Karlstad University but also to friends and acquaintances. The data is measured with SE- and LOT-tests. The issues concerned in which scope respondents experiences themselves stressed and optimistic and how the connection is between experienced stress and optimism in relation to results on the figure tests.

Hemp is an annual energy crop that fits very well in Swedish crop rotations. It is an interesting crop with many benefits, for example its ability to establish a large quantity of biomass in one year. Hemp is easy to grow and out-competes unwanted weeds through its aggressive growth pattern without the need for pesticides. Interest in growing hemp and other energy crops is currently decreasing, apparently because of high grain prices. These high prices give a higher net profit that we believe could partly cover the cost of hemp cultivation, while the hemp in turn would improve the crop rotation and thus repay its debts in the form of increased yields of other crops. The great disadvantage of hemp is the lack of knowledge about spring harvest of the crop.

Abstract Title: Ethanol for Scania?s future ? A scenario based analysis Authors: Anna Hansson and Julia Persson Tutors: Annette Cerne ? Department of Business Administration, Lund University Jonas Holmborn ? Head of Advanced Combustion, Engine Development, Scania Lennart Thörnqvist ? Department of Energy Sciences, Faculty of Engineering, Lund University Problem: Oil-based products are the dominating fuels in the transport sector but alternative fuels are currently challenging the world-wide dominance. The large number of alternative fuels that are under development at present makes the future fuel-market impossible to predict. Scania?s ethanol project is associated with a number of uncertainty factors that are beyond the company?s control.

År 2009 introducerades en ny typ av luft-/vattenvärmepump av NIBE Energy systems. Den produkten vill man nu modernisera, samt göra mer lik de övriga produkterna i NIBE:s sortiment. Syftet är att göra en förstudie inför en sådan uppgradering. Man vill ha svar på om det går att genomföra en uppgradering, genom att utgå från en annan, nyframtagen produkt.Går det inte så vill man veta varför, men finns det möjlighet så ska ett koncept på en uppgradering tas fram. Konceptet ska då ge förslag på en konstruktion, användandet av befintliga moduler, möjlighet till produktion, kostnadsuppskattning, samt kvalitet och miljötänkande.På grund av sekretess, kommer det inte nämnas vilken produkt som ska uppgraderas, eller vilket utgångsobjektet är.

The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

Drivsystemoberoende energiåtervinning är kärnan i detta examensarbete. Målet har varit att analysera pneumatikens potential att återvinna energi och agera som en gemensam plattform för alla fordonstillverkare oavsett inriktning på drivsystem. En kompressor har används för energiformsomvandling, lufttankar för energilagring och luftmotor för återomvandling till kinetisk energi. Utgångspunkten för systemet har varit att utföra så stora delar av bromsarbetet som möjligt. Hållfasthetsberäkningarna styrker att måttlig energiåtervinning är möjlig utan anpassning av belastade komponenter, så som drivaxlar.

The report is a master thesis about energy efficient measures for an underground facility Hemsö fortress.Several proposals are evaluated economically.Statistics of the electricity used and measurements of several heat pumps are analyzed to find energysavings potentials.The results indicate that several units of a dehumidification system are responsible for over 70 % of theyearly electricity cost. The air that is being dehumidified by these units can otherwise cause damage ofculturally important interior designs.The proposal with highest profit suggests an alternative method for dehumidification. The cooler in theair handling units in Hemsö fortress have capacity to dehumidify the air. However complementary fansneed to be installed to circulate humid air towards the air handling units. The solution can be implementedin three different locations within the facility.

Staden Sulaymaniyah ligger i den kurdiska delen av Irak och har på senare år utvecklats då många valt att flytta från landsbygden till den centrala delen av staden. Nybyggandet sker under tidspress och långsiktigt hållbara lösningar prioriteras inte. Målet är att ta fram ett hus som är anpassat för majoriteten av befolkningen och samtidigt få ett bra och energieffektivt inomhusklimat. En faktainsamling genomfördes för att ge bakgrundsinformation till projektet. Vidare gjordes en planlösning till huset i AutoCAD vilken har använts som grund till utformningen av huset och smarta lösningar.

Nimo Verken AB is the leading producer in the Scandinavia of drying cabinets. The construction has, with small changes, been the same since the 70s with a thermostat and a timer as controlling system. There was a wish to develop a modern cabinet which showed remaining time on a display and with energy saving functions.In this report we go through how it is possible to implement a digital controlling system, where remaining time is shown on a display and where it is possible to choose a preset ?program?.The report first presents the fundamental theory for a PIC, where we describe the different registers, how interrupts are handled, the internal clock function and how data is sent to control the different parts of the construction.Next the report presents and describes the new hardware that is needed, such as the encoder, the temperature sensor and the display.After the theory we describe how the program in the PIC may be drafted. Last in the report we have the result of the tests of the temperature variations and the accuracy of the time..

AbstractElectricity consumption is a globally increasing problem caused by the high share of electricity produced in coal power plants. These contribute to high carbon emissions when only about 1/3 of the heat generate electricity and the remaining 2/3 of the heat cools off. Combined heat and power plants (CHP) have high efficiency because they use the residual heat for domestic heating. The CHP plant often use fuels from renewable resources, giving them a lower carbon footprint, but are also depending on the heat demand. If electric powered products such as drying cabinets convert to heat powered products more environmentally friendly electricity will be produced by CHP plants, which can supplant electricity, produced from coal power plants and reduce carbon emissions.

Allt hårdare lagkrav gör att det är svårt att energieffektivisera befintliga byggnader utan att förändra deras utseende.Syftet med examensarbetet är att utreda hur stor energieffektivisering, för tre befintliga småhus uppförda under 1900-talet, som är möjlig att uppnå genom förbättring av byggnadernas klimatskal, det vill säga tak, väggar, golv, fönster och dörrar, utan att förvanska byggnadernas utseende och samtidigt bevara deras kulturhistoriska värden.Arbetet bestod av en förstudie där tre byggnader identifierades, ett undersökningsskede där information om byggnaderna togs fram och ett slutsatsskede där energibesparande åtgärdsförslag togs fram och utvärderades. Byggnader som var goda representanter för sin tid och stil söktes. Byggnader från 1910-talet, 1930-talet och 1970-talet, lokaliserades. Sedan gjordes det fallstudier med intervjuer och inventeringar. För att utreda byggnadens klimatskal utfördes u-värdesberäkningar och energiberäkningar av befintliga byggander och byggnader baserade på föreslagna åtgärdsförslag.Ingen av byggnaderna nådde efter föreslagna åtgärder ner till passivhuskravet 59 kWh/år/m2 Atemp eller BBR-kravet 110 kWh/år/m2 Atemp för en byggnads specifika energianvändning.

With a base in Ian Manners? theory about Normative Power Europe ? that the European Union is to be seen as a normative power instead of a civilian or military ? this paper seeks to contribute to the discussion about identity by examine the normative elements of the union?s policies towards Russia between 1997 and 2013. Which norms are most important and how does the diffusion look? The findings show that democracy, rule of law and respect of human rights are among the most diffused norms, and this is more than often done by using the Russian interest in economic progress. Over time the European Union has taken on a more critical approach against Russia, while still appreciating their prosperous relation when it comes to trade and energy.

The first main purpose of this essay is to describe the situation of young women today here in this part of the world concerning influences from commercial media.The second purpose with this essay is to investigate if dance could be used as a tool against all these sterotyped and superficial pictures and ideals in the industy of commersial media.With some questions I also want to get closer to the answer if dancing is a way for young women to get insight knowledge. I also describe women from dance history who experienced that dance filled them up with energy but also environment where there was oppression.This essay has a gender perspective.The methods are manly based on literature studies but information is also gathered from the Internet and from one film.My results are that dance is a very constructive way to give the young woman that force which is needed when meeting media pictures everywhere. It gives her self-confidence, body awareness, joy and strength in life..

Den negativa miljöpåverkan från förbrukning av fossila bränslen ökar kravet på förnyelsebara energikällor. Biobränsle är ett speciellt lovande alternativ. Detta projekt vill visa på möjligheten att använda gas från biobränsleförgasning som förbränns utan synliga flammor i glassmältugnar. Med bättre teknik är det möjligt både att upprätthålla produktionen och reducera kväveoxidutsläppen med ekonomiska fördelar. Biobränslena bidrar inte till växthuseffekten.
