The major part of the solid waste produced in the region is landfilled on three different sanitary controlled landfills situated outside the city center.

Interaktion och intervention : En undersökning av kommunikativa behov hos personer med afasi och dysartri i vardagliga och kliniska samtal

In speech and language intervention, the ability to interact is seldom evaluated; rather intervention is evaluated in terms of improved testresults.  If goal-setting in intervention also is based on everyday communicative needs, the relevance of the treatment may be increased and intervention outcome may be implemented in the patient?s natural environment.The present study, as part of a research-project, is based on analyses of interaction and interviews to examine everyday conversations and speech and language intervention. The aim was to explore if there is a relation between everyday communication needs and goal-setting in speech and language intervention for people with aphasia. A further aim was to investigate if there are everyday communicative needs that may form goals for speech and language intervention.Two individuals with aphasia and one individual with both dysarhtria and aphasia participated in the study. Three speech and language pathologists and two relatives also participated in the study.

Bokföringsbrott i svenska mikroföretag. : Vilka faktorer påverkar brottets svårighetsgrad?

The purpose of this master thesis is to study the correlation and meaning of current ideas and practice at the public library of Gothenburg. This was done by comparing the visions and ideas expressed by the library through the library plan, with how the daily practice looks. For the theoretical framework organizational theory is used and research data was collected both from public documents and through observations. The public library of Gothenburg were chosen for the study because of it's newly renovated facilities. The idea is that these facilities make a suitable study object of the current ideas and priorities of the public Swedish library in general.The results show that the public library practice in Sweden still rests on the original public library ideas such as offering information for free and treating every user as equal.

Den tryckta pressens framtid i en digital miljö : Med Nya Wermlands-Tidningen som exempel

The research in question examines whether a newspaper benefits from its activity on the Internet and if so - how. Today, the morning press is relatively stable, but tendencies show that there?s a decrease amongst regular readers. The extension of this may jeopardize the position of the morning newspapers in the market and several newspapers choose to publish their content on the Internet. An Internet activity is foremost about keeping the position in the market, not to make an economical profit, and to compete at the same terms with free newspapers and news sites.

Bokmärken - En historisk redogörelse med en inblick i hur de förvaras och bevaras i museala samlingar

This thesis is intended to review and create a greater understanding for the history and originsof printed scraps from late eighteenth century to the beginning of the twentieth century.A questionnaire survey was sent out to several Swedish museums, containing questionsconcerning their collections, possible exhibits, special difficulties and types of damagesconcerning scraps and their current storage. A visit to the Gothenburg city museum storagewas made to take a closer look at their scrap collection and how they were stored. Thisresearch resulted in an understanding regarding the current situation of printed scraps, whichunfortunately appears to be quite poor and inattentive. These results are presented in the firstchapter.The second chapter describes the history of printed scraps, followed by a chapter presentingrelevant printing techniques and technology. This is followed by various chapters dealing withhow the printed scrap has been used through the ages, history and development of motifs andthe album's significance.

The feasibility study was followed by a generation of ideas which contained everything from sketches to simple mock-ups with an intensive amount of thoughtful brainwork and information gathering in between. This ledto the development of a number of design concepts, both on an overall level and on different parts of the golf bag.

Uppkomst av materialspill vid nyproduktion av flerbostadshus

Construction waste from the housing industry includes all unnecessary consumption of building materials. The definition of construction waste is construction materials that has not been built in and becomes waste. Constructions waste can be divided into two types of contributions: operational and work site contribution. Some of the common construction materials in housing industry have such low usage level as 75 % and the rest becomes construction waste. Low usage of construction materials creates unnecessary costs and has a major environmental impact.

SMED implementation vid slipoperation

The thesis has investigated how Sandvik Coromant could implement the SMED principle on one of their grinders groups and what improvements it would lead to. The aim of the thesis is to identify the current situation and investigate how their setup times would be affected by SMED. The work initiated with a literature analysis about the SMED principles and then proceeded with an analysis of the current situation where the activity was time mapped. The analysis consisted of time trials of the process that the thesis would include. The time studies revealed opportunities for structural improvements to create environment for a more structured process.

Användarorienterad förarsituation för bergavläsning vid fjärrstyrt skrotningsarbete

Mechanical scaling is one of the most complex operations of all in the mining process. The operators are using both hearing, sight and feel to read the rock and to know where to scale and where to leave. They say they go on gut feeling in great extent, something that comes with experience. The scaling machine is placed into the edge of unsecured and newly blasted rock to hammer off the blocks that has become loose after the blast, but not enough to fall down. It goes without sayingthat it is a risky job.

Cassava as an additive in biomass fuel pellet production :

In this study, the effects of using fine milled cassava stems as an additive in biofuel pellet production was compared to the effects of refined starch addition. The bulk biomass fuel raw material, to which the additive was added, was a blend of spruce and pine sawdust. An experimental design in the factors cassava/starch content, moisture content and material temperature was used. Measured responses were pellet bulk density, pellet durability, amount of fines, pelletizer motor current, pellet temperature, die temperature and CV for pelletizer motor current (a measure of process stability). Each response was modeled by multiple linear regression (MLR).

An analytical model will be used to categorise and compare the three textbooks.The method chosen for this is analysis of ideas by use of ideal types.

?Det enda man aldrig kan vara säker på är om man har gjort rätt?? En utvärdering av attityder kring implementeringen och användandet av Personec

Under hösten 2008 implementerades ett nytt löneadministrationssystem, Personec, hos Social resursförvaltning vid Göteborgs Stad. Syftet med denna uppsats är dels att utvärdera hur implementeringen gick till samt kartlägga attityderna till Personec hos de personer som arbetar i systemet. Vi har valt att behandla implementeringen av Personec som ett förändringsarbete, då det inneburit en stor förändring av respondenternas vardag och arbetsuppgifter. Det finns många anledningar till varför individer motsätter sig en förändring på arbetsplatsen och vår uppgift har varit att ta reda på vilka typer av motstånd som kan tänkas finnas inom Göteborgs Stad. Uppsatsens empiriska material har insamlats genom kvalitativa intervjuer som vi har genomfört på Social resursförvaltning.
