Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.

StoraEnso decided in year 2002 to build a pulp mill in the province of Guangxi, southernChina, and also establish eucalyptus plantations to provide it with raw material. By 2010StoraEnso controls about 90 000 of planned 120 000 ha, out of 75 000 ha is already plantedwith Eucalyptus.By using better genetic material, improve the tending, selecting the sites more careful and byusing a proper fertilization regime StoraEnso hopes to increase the mean annual incrementfrom today?s 25 m3/ha, on bark, to 35 m3/ha. This study is one part in this work to increase themean annual increment in the plantation.This master thesis is the forth in a series, that has followed up a fertilization trial that startedin spring 2006 when the trial was laid out and treatments decided. The aim with the trial is toexamine the production potential of Eucalyptus urophylla in Guangxi, southern China.

Bakgrund: I dagens samhälle har varumärken kommit att spela en allt större roll för såväl konsumenter som företag. Varumärken fungerar som en ledsagare i individers sökande efter identitet och samtidigt som en gemensam nämnare eller tillhörighetsfaktor inom olika subkulturer. Företag kan med hjälp av symboliska värden sända ut signaler som stämmer överens med olika individers värderingar och på så sätt attrahera konsumenter och samtidigt ringa in en önskad målgrupp. Dock kan även det motsatta inträffa, det vill säga en annan grupp än den tänkta målgruppen kan komma att adoptera ett företags varumärke och göra detta till en del av gruppens image.Syfte: Syftet med denna studie är att identifiera och åskådliggöra hur en subkultur kan påverka det symboliska värdet av ett varumärke.Genomförande: För att uppnå syftet har det verkliga fenomenet hip-hopkulturens adoption av varumärket Adidas valts att empiriskt undersökas. Detta utifrån kvalitativa intervjuer gjorda med respondenter från hip-hopkulturen så som bland andra gruppen Latin Kings och Infinite Mass, tillsammans med personer från företaget Adidas, samt analyschefen på MTV Nordic Networks och radioproducenten Stefan Wermelin.Resultat: Denna undersökning visar bland annat på att en subkultur kan påverka det symboliska värdet på ett varumärke genom att inte enbart ta till sig de symboliska karaktärer varumärket står för, utan även överföra subkulturens värderingar på varumärkets image.

Within media and communications studies, questions of taste have often been associated with the dichotomy of high versus popular culture. The French sociologist Pierre Bourdieu has also used mass media products in his studies of class determined tastes and dispositions. In this paper the author uses the theoretical framwork of Bourdieu to examine aspects of social class and legitimate taste in the interior design magazine "Sköna Hem", a market leading magazine within it's genre of lifestyle magazines in Sweden. A specific type of feature article, where a real-life home is portrayed, is studied using the critical discourse analysis of Norman Fairclough. The homes portrayed are predominantly affluent and display elements of conspicuous consumtion as mediated through legitimate taste and cultural capital.

År 2008 var 43 miljoner barn under fem år diagnostiserade med fetma. Fetma anses som en kronisk/långvarig sjukdom och ett folkhälsoproblem med behov av förebyggande arbete för att förhindra framtida konsekvenser. För beräkning av kroppsfett används Body Mass index (BMI). BMI är det mått som används världen runt och räknas genom att dividera kroppsvikt i kilogram med längd i meter i kvadrat. Att ungdomarna drabbas av fetma beror främst på dåliga matvanor, obegränsad tillgång till kalorier i form av kolhydrater och fett ofta i kombination med mindre fysisk aktivitet.

Comfort analyses regarding human induced vibrationsIt is not too common among civil engineers in Sweden to perform comfort analyses considering the vibrations caused by human activities. In addition, the Swedish standards lack requirements to be used for comfort analyses in design of floor-systems. The demand for large spans in combination with slender slabs, is today a reason to investigate the floor-system constructions, in order to prevent disturbing vibrations and oscillations.The purpose of this thesis is to create a guide for how a comfort analysis, considering vibrations, should be implemented. Göran Svedenbjörk who is an expert in structural dynamics has been interviewed where he presents his latest project Värtaterminalen and answers some questions about vibrations due to human activities.Floor-systems, consisting of concrete slabs supported by steel or concrete beams, have been investigated with simulations in the finite element program Abaqus. In the simulations, the influence of various factors on the natural frequency of floor-systems and the acceleration level caused by dynamic loads, is studied.

The demands for higher production yields and better quality materials from the forests are increasing globally. Tree breeding programs are directed to meet the future demands on forests. In order to capture the full benefits from the breeding programs, clonal propagation is necessary. For most conifer species, somatic embryogenesis (SE) is the only available option for large scale clonal propagation of Elite clonal material. For Norway spruce (Picea abies L.

The stability of railway embankment is essential for safe transport. In order to ensure safe transport, water should be allowed to freely drain. Furthermore, as the engine driver has to be able to see signs, and people working on the embankment are supposed to easily see flaws on the rails to ensure safety for the passing trains, plants should not be allowed to grow on the embankment. In Sweden there are 12 000 kilometers of railway tracks and 25?30 % of them are treated for weed control every year.

On July 22, 2011 a bomb detonated in the government building in central Oslo in Norway and eight persons died. Later that day, 69 people, most of them youths, were shot down and killed on the island of Utøya by a uniformed Norwegian man.The purpose of this study is to analyse Anders Behring Breivik's personality and explain why he became a killer. I have used a Psychobiographical narrative method, which serves to describe the mind of a human being, linking the mind to motives, scripts, unconscious ideas and personality.My primary sources are Breivik?s Manifest: 2083 A European Declaration of Independence and the inter-views with his father and stepfather, together with the Psychiatric Reports which were submitted to the District Court of Oslo. I have analysed in what way Breivik?s childhood influenced his behavior as an adult.

An increased number of participants in the construction industry is asking for accompanying terrain models to the project in order to get a better understanding of the field. When the desire to create buildings that fit together nicely with the surrounding area is increasing, it becomes more and more important to have a broad base of knowledge about the ground on which the building is to be erected. Terrain models are also very useful in the planning of logistics, documentation for landscape architecture projects, and billings for mass calculations.Surveys for creating terrain models can be performed with laser scanning. The advantage of laser scanning is the time-effective surveying, the detailed information as well as the ability of application in complex environments resulting in a cost-efficient project. With this in mind our thesis was defined in collaboration with the company Bjerking AB in Uppsala in order to investigate if there were any softwares suitable for terrain modeling.

SammanfattningBakgrund: Dagens stillasittande livsstil med ökat intag av energigivande ämnen resulterar i ett konstant anabolt hormonellt påslag. Detta leder till ökad övervikt och andra välfärdssjukdomar. Det rekommenderas att individer håller sig till en hög måltidsfrekvens med jämna mellanrum under dagen. Detta har börjat ifrågasättas med konkurrerande alternativ som involverar en tidigare samhällslivsstil så långt som 10 000 år sedan, då måltidsfrekvensen inte kunde planeras på samma sätt som idag.Syfte: Syftet är att under sju veckor undersöka effekten av två stycken veckovisa 24-timmars periodiska förbud mot intag av energigivande ämnen, med implementering av fysisk styrketräning och dess effekt på lean body mass (LBM) och fettvikt hos yngre individer.Metod: Två separata 24-timmars perioder av fasta i samband med tre separata styrketräningstillfällen genomfördes per vecka under sju veckor. Kroppsmått gällande kroppsfett i procent, fettvikt i kilogram (kg), kroppsdimensioner i centimeter (cm), LBM och total kroppsvikt i kg togs innan och efter studiens genomförande.

Examensarbetet utfördes på University of Florida vid Department of Mechanical and AerospaceEngineering i deras Energy and Gas Dynamics Systems Laboratory. Laboratoriet forskar på enny gasturbincykel som producerar kraft, värme, kyla och vatten. Cykeln är kallad High PressureRegenerative Turbine Engine (HPRTE) och kombinerat med gasturbincykeln är ettabsorptionskylsystem (VARS). Kylsystemet drivs av spillvärme från avgaser som cirkuleras igasturbinen, den producerade kylan används för att kyla ned högtryckskompressorinloppet.Syftet med det här examensarbetet är att undersöka möjligheten till att kyla ned inloppet tillkompressorn till temperaturer långt under fryspunkten för vattnet i den fuktiga gasen. Om gasenskall kylas till nivåer under fryspunkten måste vattnet föras bort från gasen.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

In the pilot plant at Hammarby Sjöstad, Sjöstadsverket, several new methods are tested in order to achieve a good use of resources. When a new technique is considered it is often the performance of the technique itself, under given conditions, that is evaluated. However, in order to evaluate the overall function the whole picture is needed. With a system analysis it becomes possible to make a comparison where all the positive aspects are put up against the negative ones, for the technique itself as well as its requirements. In this way the influence that minor components have on an entire system can be considered.This report presents a system analysis of an anaerobic membrane reactor (MBR) with a VSEP-membrane (Vibratory Shear Enhanced Process).
