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 study aims to investigate how and why teachers use social media to reach their students, and how they handle different levels of computer literacy among students.The purpose of this study is to investigate the experience of teachers using social media in their teaching. I have done interviews with two teachers, who use social media in different ways. One of the teachers makes her students publish their work on the Internet on wiki-spaces, and the other one use Facebook for discussions and teamwork. This report uses the pedagogy theories laid forth by Vygotskij as a vantage point to analyze the answers from the teachers. I have also looked at some of the published student texts on the Internet.This study concludes there are students who don?t have access to computers and Internet at home.

Title: When municipalities are keeping upAuthors: Hansson Käll, Ida; Jonasson, MikaelaTutor: Waks, CarolineCourse: Bachelor thesis, 15hp, Department of Business Studies, HT 2010Background: During the recent years social media has evolved into a powerful communicative medium. From an organizational standpoint social media has become a way for organizations to get closer to, and create a dialogue with, their environment. Swedish municipalities have began to use social media in their daily communication with the environment, but a problem has been raised about how public organizations should organize their social media when formal guidelines from the government are missing.Objective: The objective of this thesis is to examine how eight Swedish municipalities have organized their use of social media due to the lack of official guidance from the government, and also what difficulties that have occurred during this process.Method: The method used is qualitative with data collected through interviews with one respondent from each municipality.Results: The result show that the organizational solutions varies through each municipality but also the choice of social media. It has been important for municipalities to have someone in charge of the new communication tool since social media is a fast and communicative channel. Seven out of eight municipalities have already developed or are in process of developing their own formal guidelines on how to use social media.

The effects of social media usage in a professional context, specifically the effects on social media usage in relation to leadership have been studied in order to determine weather or not usage can be productive for leadership in general. The study concludes that there are several benefits as well as drawbacks to leadership in using social media, but has yet to conclude weather productive or not. This study gives an overview of a relatively unexplored subject.Leadership in terms of leader, communication and group dynamics have been defined and explained in accordance with existing literature. A  brief review of computer and Internet history attempts to explain the formation and evolution of social media. Risks in terms of risks related to leadership and risks related to IT-security are taken into consideration and have been briefly explained.

Syftet med uppsatsen är att undersöka den diskurs som följde i svensk media efter migrationsverkets beslut att ge syriska flyktingar permanent uppehållstillstånd.Metoden som vi har utgått ifrån är kritisk diskursanalys och innehållsanalys. Som data har vi valt ut tolv artiklar och två TV-program.Resultatet visar att media äger den makt som gör att de får avgöra hur ett sådant beslut ska presenteras och diskuteras. Resultatet visar även att media använder idag en annorlunda diskurs jämfört med 1980 och 1990 talet.Media kan med sin makt avgöra vem som ska/inte ska uttrycka sig. En ?Vi? och ?De? skapas av media som skiljer mellan den etablerade och den oetablerade i samhället.

In our case study we investigate how media chose to illuminate the process of court proceedings concerning a one specific rape case in Sweden during the spring and autumn 2007. For our study we have chosen to investigate two Swedish daily newspapers, one known to be a serious morning newspaper, Dagens Nyheter, and the other an evening tabloid newspaper Expressen. We would like to see whether the reports of the trial diverge and if that is, how they differ.The rape took place in Stockholm?s posh area named Stureplan in March 2007. The two men 21 and 25 years old, accused for the crime were acquitted after the first instance.

The society of consumption exposes us to a lot of information, where advertisement constitutes an extensive part. Due to its expanding, advertisement receives a natural and obvious space in our everyday life. This study aims to investigate how social and cultural values can be mediated in advertisement. The focus has been put to ideas related to health and fitness in the advertisement of power drinks. The thesis takes social constructionism as a starting point, and combines image- and critical discourse analysis in purpose to analyze the pictures.Sociology of consumption, construction of identity, lifestyle and everyday life all constitute an essential part of my analysis.

In this study we try to focus on the costs for wear parts on different type of soil tillage machines and at Väderstad Rapid drilling machine. We have studied some of the leading types of cultivators and disk harrows. Among the cultivators we have investigated Väderstad Cultus, Dalbo Dinkomax, Horsch Tiger and Terrano. At disk harrow we have looked at Amazone Catros and Väderstad Carrier. We have made more detailed study on costs for wear parts, working depth, driving speed and diesel consumption.

The aim of this study was to seek knowledge about how the media audience interprets media representations of immigrants as well as the construction of ?us? and ?them? that is created from the media report.We implemented two focus group interviews, one containing only ethnical Swedes and one holding a variety of people with different ethnical backgrounds. The focus groups got to read nine news articles from different Swedish news papers selected by us, based upon previous research. These articles got to serve as the basis of the discussion.To supplement the focus groups, which got to represent the media audience, we also interviewed two different persons we choose to call informants, whom are both immigrants and are or have been politically active and often appear in local media.The interviews were our empirical material which was used for analysis. The method we used was qualitative analysis of meaning and was based upon a hermeneutic starting point, meaning that all humans are interpreting beings.

How do the Swedish police get represented in news media and how does that representation differentiate from other media channels where the police have full control over what is said? Through a discourse analysis of news texts and extracts from the police own webpage and Facebook page, we claim that the discourse in newspapers and the discourse on the webpage and Facebook page is pretty much the same, only packaged differently..

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

This thesis investigated the possibilities to resume cultivation of an old manor house built of timber and what this would mean from an energy and moisture perspective. The building in this case study is named Sofiedals mansion and was built in 1858 in Valbo 11 kilometers west of Gävle.The structure of the house was documented and used as a starting-point for carrying out calculations focused on energy and moisture aspects. With the help of a number of computer programs and a conducted air tightness test, the buildings energy consumption were calculated and compared with the current building regulations.In addition, the building was analyzed considering energy retrofitting and what it meant for moisture problems. The energy retrofitting consisted of additional insulation, decreasing the buildings permeability through air sealing; window and door replacements. When a building is equipped with natural ventilation it is difficult to know its precise performance and how an energy retrofitting affects it.
