The purpose of this report is to investigate the possibilities with drain water heat recovery (DWHR) in residential buildings. Information and relevant theory has been collected and summarized in this report. Calculations have been done for given scenarios to evaluate profits. DWHR heat exchangers use simple technology and have long life-time. The heat exchanger is connected to outgoing drainage pipe and incoming cold-water supply so countercurrent flow is accomplished.

AbstractTitle: Wireless Fidelity ? A Scenario Analysis Authors: Mellberg Ola, Technology Management, Lund UniversityMårtensson Jens, Technology Management, Lund University Tutors: Andersson Jens A, Faculty of Engineering LTHKarlberg Johan, Sony Ericsson Mobile Communication ABSvensson Claes, Lund University Discussion: The most significant impacts on the telecom industry over the past decades have been the rapid growth of the Internet and mobile telephone services. Currently these two worlds are converging. Moreover, the fast expansion of wireless high capacity Internet access, increased distribution of local/public hotspots and rapid development of wireless network cards have opened new opportunities for the mobile telecom industry. Research Questions:To what extent could the explosion of local and public wireless networks, using WiFi technology, affect the future telecom industry? Who will ultimately master the WiFi innovation and to what degree could this innovation open new possibilities for external players to enter the mobile voice industry? Purpose: The purpose of the Master Thesis is to provide Sony Ericsson Mobile Communication AB with the most transformational scenarios, which will enable employees to recognise patterns and interpret the meaning of WiFi-related events as they unfold.

The acid deposition of sulphur- and nitrogenoxides from combustion of coal and oil cause acidification that lowers pH and gives increased contents of metals and altered aquatic biodiversity in the stream. The liming of lakes and streams, which was introduced to resist the acidification, demand large economic resourses despite of the decreased deposition of the acidifyng substances. Some of the streams are influenced by the acid deposition, while others are naturally acidic. It is therefore importaint to separate the anthropogenically acidified waters from the naturally acidic, in order to optimize the use of governmental fundings for liming. This thesis aims to estimate the acidity status and impact of acidification on 24 catchments upstream liming dispensers, which is part of the liming activities at the County of Dalarna.The acidity status of the streams was classified according to the Swedish Environmental Protection Agency old classification system (Naturvårdsverket 1999) as very acid to acid, with small ability to withstand a pH-change (alkalinity) due to acid deposition.

This essay examines how age, power and agency is represented and reproduced in contemporary Swedish picture books.This is done through a combination of discourse analysis and literary analysis.It uses theoretical perspectives from sociology, and views childhood as a social construct. It sees discourse and language use as both representing and constructing social reality in the tradition of Norman Fairclough and critical discourse analysis. The main results is that the discourses of childhood in the material construct children as a separate group in society, and childhood as a special time in life. Children is portrayed as both social actors and in need of protection from adult themes and worries..

The following essay aims at the interplay between regional och municipal growth work, and theway cultural heritage is used in growth work strategies. The main issue has been whether theregional strategies are followed up in the municipal strategies, which has been investigated bymeans of question which impact the region?s strategies has at the local level.The essay draws upon an instrumental perspective on cultural heritage and cultural environment,here defined as instruments in the national development and growth efforts. Three publicationsthat highlights potential roles of cultural heritage and cultural environment to act as instrumentsin the regional and municipal development and growth efforts has thereby been selected astheoretical models. These roles has further been summarized in a tabular form as a schematicdivision of main themes with sub-categories, used as a framework for deciphering the regionaland municipal strategies.A content analysis of available strategies at both regional and local levels have been used as amethod for investigating the issue, where the role of cultural heritage and cultural environment(as defined in the schematic table) has guided the reading.

Purpose/Aim: The aim of this thesis was to study Sydsvenskans coverage of the police crisis in Skåne 2009.Material/Method: The study is based on 26 articles which has been analysed within the frames of Norman Faircloughs Critical Discourse Analysis..

To be able to evaluate different radio waveforms in a laboratory environment FOI in Linköping has developed an experimental system for radio communication called Rasmus. The system consists of a transmitter, a channel emulator and a receiver. The transmitter modulates a digital signal to a desired analogue waveform. The channel emulator is used to simulate a real radio channel. The channel emulator distorts the signal by splitting it up in several propagation paths.

Large retirement numbers and fierce competition of available labour, results in municipalities have to be more attractive as an employer. One way for the municipalities to fulfil their staffing requirement is partly to increase their recruitment efforts, and partly to educate their existing employees. Discussions about the supply of competence are therefore pressing within municipal activity. The aim of the study was to investigate how the concept of competence is used within a municipal administration. The method that has been used is Norman Fairclough?s critical discourse analysis, a method that allows multi dimensional analysis.

Background: Atopic eczema has increased in the last decade among children. The nurse can have a major role to prevent the disease. Aim: the aim of this study as to describe the nurses´ work in primary care with prevention to families with atopi with focus on atopic eczema among children. Method: A literature review based on analysis of fifteen scientific articles was done. Results: If the child was breastfed both positive and negative effects were evident.

Introduction: Public health is based on the determinants of health. They mutually influence each other. Structural factors and life conditions contribute to health inequality both within and between countries. Health inequality can be seen between different social groups, which can be the cause of differences in living conditions, health behavior and disease vulnerability. One of the consequences of this is segregation which means that certain groups live apart, where this distribution can be connected to economic resources and/or ethnicity.

The purpose of this paper is to compare the content and political message in the election posters of the political parties Sverigedemokraterna and Feministiskt Initiativ. This is achieved through a qualitative content analysis combined with text and rhetorical analysis as well as semiotics. Out of all the election posters from Sverigedemokraterna and Feministiskt Initiativ with national spread, eight were analyzed. The conclusions of this analysis are that both political parties prefer posters with high text content with the main purpose of gathering votes, and that persons were used as motives with the objective to present the party representatives and strengthen their perceived ethos..

Due to an increased population in cities the need of densification of cities increases. This means that the amount of ecological elements in the city is at risk of decreasing. Ecological services contribute to the city?s climate by softening the negative impacts that densification of cities means. Thus increases the will and ambition in city planning in to preserve greenery.This is an interdisciplinary thesis within the subject of geography that studies Biotope Area Factor (BAF), a planning tool that is used in city planning with the purpose of compensating for lost ecological services associated with new housing estate.

This Master Thesis has been carried out in cooperation with Silva Sweden AB.

This master thesis summarizes contemporary theories on secularization processes in the Western world, and compares these with the example of Sweden, which by many scholars is considered to be the most secularized country in the Western world.I do this by dividing the most influential theorists in five different groups. In each group I explain how the theorists formulate and motivate their positions. These groups are:1) The secularization paradigm, where secularization always accompanies modernization. (Therorists: Steve Bruce and Peter Berger (in the 1960s)2) The paradigm basically accepted, but revised to depend on existential security, rather than modernisation as such. (Pippa Norris and Ronald Inglehart)3) Religion returned in the public sphere.

This report describes the construction process and the aspects that should be taken into consideration. It includes models of decision and how these can be used in practice. Planning of a building project is very important for a successful execution. This will be the foundation of problems that will occur during the production. In the planning process people with different positions, search for the best suitable building methods.
