Ericsson develops a new stripline directional coupler. Its design is described in appendix B and differs from the directional couplers Ericsson uses in current products. The new directional coupler will be used for transmission power measurement in future UMTS 3G base stations.The most important parts of directional coupler theory are presented. It is necessary to study this theory to understand how the coupler works and how it should be designed to get good performance.Optimal directional coupler termination component values to get high directivity and broad directivity bandwidth have been investigated.The trim screws trim ranges have been studied.A simple analysis of serial production performance when termination component tolerances are taken into consideration has been done.The resistance components reactive (inductive/capacitive) characteristics at 2.14 GHz have been analyzed.The directivity performance limitations of the directional coupler, when Ericsson?s band pass filter is connected, are investigated.Design changes leading to better performance are proposed.

The purpose of this thesis is to expose the political myth in the West about the ageing population seen as a threat against the welfare society. To do so I have described what a political myth is, and showed how it is presented in the most influential newspapers and organisations in the West. I have also presented alternative perspectives to the dominating view on the ageing population and it's impacts on welfare. In this way I have tried to point out that the subject has a political dimension. In the thesis last section I compare the message presented in the newspapers and the organisations with the characteristics of a political myth.

This is a thesis report from SLU in Skinnskatteberg, the Swedish university of agricultural sciences. This study is an evaluation of a course in attitudes and behavior for participants of the ETT- project led by Skogforsk, the forestry research institute of Sweden. They do research for the benefit of Swedish forestry. The ETT-project is a project where there are both 74 tons ST-trucks and 90 tons ETT-trucks in test on the public roads. This study is concentrated on the ST-trucks and their drivers, company owners and logistics managers. The evaluation is done by interviews with the various participants.

This work has treated the subject of gender, with demarcation against the norms regarding appearance and beauty, conveyed by the media and how it affects society. This is expressed through social satire cartoons. This work has also led to an exploration of the importance of a personal drawing style and how it manifests itself..

GNT Group is a Nordic/Baltic wholesaler that distributes products in the IT, entertainment and home electronics sector. GNT is facing problems with inaccurate inventory levels which can lead to unnecessarily high inventory carrying costs or lost sales. Currently the decisions about when and how many to order are made somewhat arbitrarily by the responsible personnel. Their decisions are based only on some brief sales history and on experience. GNT wants to develop its ERP system to be able to support the purchaser in these and other related decisions.

Background: Knowledge of customer needs is a key factor in companies? struggle to develop successful products. Several studies illustrate that the main reason for failure in product development is lack of customer understanding. Lately considerable changes have occurred. Large-scale mass production is continuously being replaced by customer orientation, especially in the high technological market.

The complexity of the mast cell is becoming more prominent. From being the cell recognized just to contribute to allergic inflammation it is now also associated with wound healing, protection against tumor growth and in recognition and defense against a wide range of pathogens. The location of the mast cell in the barrier between the external and internal environment of the body enables the cell to quickly respond to invading bacteria, virus and parasites. Diarrhea due to Escherichia coli infection, listeriosis, toxoplasmosis, Newcastle disease and bovine respiratory syncytial virus are examples of mast cell activating diseases that can affect animals in, as well as outside, the agricultural sector. Additionally, ticks and tick-borne diseases are of concern.

In this study the author attempts to identify factors that are determinants for why some pupils in Swedish grade school have high status in comparison with their peers. The study takes on the characteristics of both an ethnographic and a literature study by comparing the findings of interviews carried out with students of a first grade class with previous research. The study identify several tools for analyzing of how status may be understood in specific situations.The study also finds that important factors for gaining high status amongst children in aschool classes might be the ability to apply access strategies to get accepted in social interactions, such as game play, have the ability to create games that are enjoyed by peers and social skills, to name a few. Overall the study shows that children's game play with each otherare crucial for their social interactions and their social position. The study also show that children that have earlier established relationships with other children in a specific group alsohave a better opportunity to establish a high status position..

Nanotechnology, one of the most interesting sciences today will no doubt have an enourmous impact on tomorrow's society and industry. One of the most interesting nanomaterial that has been discovered is the semiconductor quantum dot (QD). This material shows interesting novel properties such as a size-dependent band gap, which is an effect caused by the quantum confinement effect in all three dimensions. Due to this phenomenon the absorption spectrum can be tuned to the desired value by adjusting the size of the QD.This thesis aims to investigate how the solvent ratio of H2O/Ethanol affects the optical and structural properties of copper sulfide QDs manufactured in a chemical synthesis way using modern microwave heating. The process of manufacturing QDs using chemical synthesis often involve a capping-agent to prevent the QDs from agglomerate into bigger structures.

Till följd av att allt fler barn sondmatas har även svårigheterna vid övergång till oralt ätande ökat. Omhändertagandet av dessa barn görs lämpligast i team med exempelvis logoped, dietist, sjuksköterska och läkare. Syftet med föreliggande studie var att undersöka hur omhändertagande av barn med ätsvårigheter ser ut med fokus på sondmatning. Datainsamling skedde genom en fokusgruppintervju med vårdpersonal som arbetar med barn med ätsvårigheter. Transkriptionen analyserades, baserad på Grounded Theory, genom meningskodning.

The aim of this paper is to analyse the social movement Planka.nu with reference to the theory of new social movements in order to engage in a discussion about the presence of ?old? tradition and ?new? trends. As well as empirical, the purpose is also theoretical and methodological: to examine, and extend, the discussion about new and old social movements. A qualitative method is used. The analytical framework is based on a combination of theories of social movements and new social movements.

In the media richness of everyday life, the encounter with information graphics ishappening on a daily basis, whether we are aware or not. With the development andeasy access of technologies, new ways to create and display information graphics hasemerged. Among them, the animated information graphics, which in the few pastyears appears to have increased in popularity on video sharing websites such asVimeo and Youtube. In the genre of animated information graphics, there seems to bean inherent diversity regarding the design characteristics. In this study we exploredliterature and research on information graphics and related subjects.

Bakgrund. Våld inom institution är ett problem vilket medför konsekvenser för både personal som för medpatienter. Kvinnor som vårdas för psykiska besvär har varierande diagnoser och är i vissa fall extremt svårvårdade, vilket även kan visa sig i våldsamma handlingar. Självskadande beteende är ett väletablerat begrepp i samhället men dess yttring och påverkan för att begå våld inom institution ter sig ännu inte helt klarlagd. Syfte.

Studiens syfte har varit att undersöka hur fritidspedagoger säger sig arbeta med avkoppling och lugna platser i fritidshemmets inomhusmiljöer samt vad som påverkar detta arbete. Metoden för studien var kvalitativ och sju fritidspedagoger i norra Sverige har intervjuats. Med hjälp av ett sociokulturellt perspektiv har resultaten analyserat gällande hur detta kan påverka barnens lärande. Några av de viktigaste resultaten är, trots buller, trånga lokaler och stora barngrupper, att det arbete som görs med avkoppling och lugna platser visar på möjligheter till bland annat situerat, distribuerat och medierat lärande. Lärande som både handlar om att skapa tillsammans med andra och att lära känna sina individuella behov i en social kontext.

AbstractIn this essay I am examining the representation of popmusic with particular focus on gender and identity in two youth magazines called Kamratposten and Julia. Using the method of Norman Faircloughs critical discourse analysis I have studied ten interviews with popmusicians from each magazine based on the theorys of representations, discourses within popularmusic and queer theory. The intention with this study was to examine how popularmusic is represented in youth magazines. If the magazines were reproducing femininity and masculinity in the interviews with the musicians, and in the representation of popmusic in the magazines. And also if there were any differences and similarities between the magazines regarding the representation of popmusicians.The analysis lead to the conclusions that how popmusic is represented in the magazines depends on what the magazines wan´t to represent on the basis of their target groups and ideologies.
