A wastewater treatment plant has the task to refine the wastewater from substances that should not be released into the environment. The decomposition process can, in a simple way, be described as follows: micro-organisms breathe oxygen and eat unwanted substances. The environment in which the micro-organism lives is known as sludge and the correct amount of oxygen available in the sludge is important for the decomposition to be effective. The oxygenation of the sludge alone stands for about 30% of the plant?s energy consumption.

This Bachelors exam is about young adults and their use of Mobile Social Network System.The use of mobile social media has become more common in today?s society, ranging fromteenagers, the dominating internet users, to the elderly. The traditional purpose of use inmobile phones, the voice communication from one place to another, has in Sweden beendominated by text communication instead. Along with the development of Smartphones andthe mobile interface, the births of mobile social media have increased in the market.Reports have shown that of all the devices with the possibility to connect to social networks,the one kept closest to our bodies is the mobile phone. One of the advantages of using thephone for mobile social media is that you can easily and smoothly update whenever andwherever, within one arm?s reach.

Föreliggande arbete tar sin utgångspunkt i Försvarsmaktens befintliga förmåga att verka med pansarvärnsrobotar. Med syfte att undersöka om det eventuellt finns ett tomrum att fylla för pansarbrytande robotsystem och att jämföra befintligt system mot föregående och ge förslag på önskvärda förmågor. Ur historik, äldre studier, teknisk data från föregående system och intervjuer dras slutsatser som ligger till grund för värderingar av det existerande behovet. Resultatet visar att pansarvärnsrobot 57 har god möjlighet till att lösa given uppgift om systemet tillförs i större omfattning inom skytteförbanden. Miljön styr taktiken, taktiken styr nyttan vilket i sin tur genererar effekt med systemet.

Syftet med vår uppsats är att undersöka debatten om pornografi i den feministiska kulturtidskriften Bang mellan åren 1991 och 2011. Vår metod och teoretiska utgångspunkt är diskursanalysen med sin socialkonstruktivistiska grund. Med hjälp av denna har vi analyserat 25 artiklar som handlar om pornografi. Våra forskningsfrågor kretsar kring hur debatten förändrats över tid, och vilka teman som varit mestcentrala. De grundteman vi analyserar går under rubrikerna: Förtryck eller frigörelse,att vara feminist och konstruktionen av genus.Vi har kunnat urskilja två huvudsakliga läger: porrmotståndare och anti- porrmotståndare.

The main topic of this thesis is to evaluate the impact on the usability of web pages when using responsive web design, a concept for developing web pages whose design adapts to the screen size being used. This is done by creating a responsive prototype based on an existing web site. A number of usability tests are conducted on the two versions of the site in order to compare the time to complete the tests and to observe the behaviour of the test participants. The tests are conducted on desktop as well as on mobile devices with varying screen size.The number of test participants was relatively low, and so the quantitative result is not statistically valid. However, the conclusion is that the most effective combination is to use either of the sites on desktop format.

Syftet med denna litteraturöversikt var att skapa en översikt över vad som kan ha betydelse för bärbara elektroniska teknikstöds användning som kompensatorisk åtgärd för vuxna personer med förvärvad hjärnskada. De 24 artiklar som ingick i studien analyserades med metoden innehållsanalys. Inklusionskriterier var artiklar utgivna efter år 2000 och vuxna försökspersoner. Analysen resulterade i fyra kategorier: användningsområden för elektroniska teknikstöd, design och funktion hos de elektroniska teknikstöden, omgivningens betydelse för användande och individuella förutsättningar för användande av elektroniska teknikstöd. Endast en artikel var skriven utifrån ett arbetsterapeutiskt perspektiv.

In this degree project I have studied how an anti-discrimination bureau can adapttheir online information to the target group ? immigrants who only have modestunderstanding of the Swedish language. This group is often subject of discriminationmatters, and therefore it?s important that they can take part of the information.To find answers to my questions I have studied different relevant theories, performeda readability analysis on the online information and have had qualitativeinterviews with representatives from the target group. I have also tested my rewrittentexts on both representatives and other readers.The result from my studies has shown that it is words that are the most difficult inthe current online information, while length and structure of the sentences are alsoof importance when it comes to the readability.

With the purpose of finding the motives behind use, production and reuse of Open Educational Resources (OER), the writer has conducted a qualitative survey. The three main questions in this two years master?s thesis are:? Why do people use others? unmodified OER?? Why do people produce OER?? Why do people alter and reuse OER?The theoretic framework is built around Manuel Castells? network society, with its social and efficiency seeking dimension, along with the Knowledge commons. Some pedagogy is included as well.A web survey was distributed to 796 users of the Connexions OER repository. 95 responses were received.

Den 1 januari 1994, samma dag som den Mexikanska staten blev medlem i frihandelsavtalet NAFTA, kunde man höra ett ?¡Ya Basta!? runt om i delstaten Chiapas i sydöstra Mexiko. Denna uppsats behandlar den Zapatistiska motståndsrörelsen utifrån gramsciansk och neogramsciansk teoribildning för att förklara deras kamp som en reaktion på den rådande neoliberalistiska ekonomiska globaliseringen. Genom att studera deras ideologi och handlingar så menar vi att de utgör en del av ett kontrahegemoniskt motstånd beläget inom den nya globala anti-globaliseringsrörelsen som i sin tur utgör en del av det globala civila samhället. Zapatisternas struktur och metod har, som ett resultat av den ekonomiska globaliseringen, omvandlats och anpassat sig för att kunna föra sin kamp och visa på att alternativ till neoliberalismen existerar..

This thesis studies the negative impact that control signal saturation may have on a controlled system. Different methods that are used to compensate for this problem are also studied and evaluated. Both sensitivity to disturbances and the effect the method has on the systems'ability to follow a reference signal will be examined. Stability will be discussed, but no conclusions whether the systems are stabilized or not can be drawn. Control signal saturation will lead to a slower behavior in general.

This Master?s thesis aims to map and analyse publishing patterns at two academic departments at the University of Gothenburg - the department of Physics and the department of History. The investigation has been guided by a set of questions: Who chooses to publish their scientific outcomes? In which forums do they publish findings? In what kind of media are the results published? What type of findings get to be published? The departments' publication lists have been examined, covering the years 2004-2007. Furthermore, ten scientists have been asked to describe factors contributing to their individual publishing pattern.

This thesis examines the verification of the terms and conditions stated in contracts based on the Public Procurement Act. In March 2013 the Swedish state procurement commission released " Good Business - A Strategy for Sustainable Public Procurement " (SOU 2013:12), which found that the proportion of control and verification is relatively low. The thesis examine how verification is carried out and looks for an explanation to why verification is not more oftenly performed. To answer these questions two care studies, based on seven semi-structured interviews, is presented as the empirical material. Network theory has been used to analyse the empirical results, and aspects of commonly used theories such as contract management and "Markets and Hierarchies" by Williamson has also been taken into account.

Enligt kommunikationsmyndigheten PTS finns det cirka 10miljoner mobiltelefonabonnemang endast i Sverige. Telefonerna innehåller operativsystem där det tillåts mängder av olika sorters program. I och med att Apple 2007 introducerade sin iPhone exploderade marknaden för så kallade Nomadic Devices. En telefon som mer är tänkt att fungera som någon form av handdator. Dessa telefoners utformning och funktioner möjliggör för utvecklare att ta fram mer avancerade program än man tidigare sett för mobiltelefoner.

The municipality, of Gatukontoret in Local government of Borås has in the long run, a required need to look after the current heating devices (the gas production plant) in sewage treatment plant, called Gässlösa. The practical work of the examination is about, trying to find a better way to take care of the current heat recovery. That may be one way or another, rather easy to implement in the existent construction.Through the work to increase the efficiency of the gas engine, implement of some external cooling system by heating exchange device. That gives an opportunity to heat (primary) the digester, (but even all internal public areas) with its own superfluous heating.The report shows that if the management group may invest 422 704 crown to implement a heat exchanging device, it gives more space to reduce the need to buy expensive external energy. Gatukontoret´s pay off time, for buying machines, is 20 years, with reservation to calculate with 4 percent internal interest, leads to the yearly mount of 31103 crowns.If Gässlösa increases the gas engine time in (effective) duty approximately (correspondingly) 48 hours a month the entire investment will generate a profit in January in year seven after the implementations.
