The purpose is to generate knowledge about webexhibits as a cultural manifestation and medium by studying the experience and actions of its visitors. To achieve the aim the paper explores the methodological questions of how to study webusers. Theories about the exhibition as a medium and the web as a virtual area of exhibits have been used to understand and interpret the results.
Biologiska behandlingsmetoder för rening av rejektvatten från biogasproduktion
In this literature review the characteristics of two free-floating macrophytes, water hyacinth (Eichhornia crassipes) and duckweed (Lemna sp.), and two microalgae, Chlorella and Scenedesmus, have been examined regarding their suitability as efficient nutrient removers in the treatment of wastewater with high levels of nutrients and suspended solids from a biogas plant in Loudden. The needs required for the plants to be able to grow in wastewater and the amounts of biomass they can produce have also been studied. The results show that Chlorella is capable of a very high uptake of nutrients in photobioreactors with high nutrient loadings. With an ammonia uptake maximum value at 10900mg/m2/d Chlorella outshines the other organisms in this study. The test organism that performed the closest to Chlorella in terms of nitrogen uptake was water hyacinth with an uptake about 1602mg/m2/d.
Vedrötor i stadsträd : biologi, detektionsmetoder och förebyggande åtgärder
Urban trees have very little in common with trees on natural sites, such as forests or pastures. Trees in urban environments are often planted in packed soil and in small volumes. This can lead to decreased availability of water and oxygen, as well as deteriorated ability for the soil to store nutritional elements. Also above ground the tree usually have limited space in cities. Regulations on free height over roads and cycle tracks demands high stems at an early stage of their development.
Samhällen i Kris : När Washington Tar Över
Dissertation in political science, D-level by Niklas Andersson, Spring Semester 2010. Tutor: Malin Stegmann McCallion?Societies in Crisis ? When Washington Take Over?An economic meltdown wreaks havoc on the world and has plunged the Western world into a spiral of economic stimulus in order to keep their way of life intact. At the same time the same institutions that support these countries have had another agenda for more unfortunate and less influential countries where nothing has been free and everything been to a price of self-sacrifice in order to get the consent of the IMF and the World Bank. Everything according to the points stated in the so called Washington Consensus.The purpose of this dissertation is to research what impact the Washington Consensus has on the state in terms of power over the market and sovereignty.

Stadsodling som begrepp i Sverige - bakgrund, nulägesbeskrivning och tänkbar utveckling
The structural rationalization of rural firms in Sweden has led to many new creative ways of developing companies. The agriculture sector is characterized by the need of capital in form of buildings, labor and inventory. The rationalization process has led to free capacity in rural firms when new technology make buildings and inventory not longer necessary for the production process. To get a better cost coverage this free capacity can be used to start-up new business areas that help the rural firm to growth.The study aims to identify factors that motives entrepreneurs in rural firms to develop new business areas. The purpose is also to analyze driving forces that lies behind development of rural firms and the forces that support or not support development in rural firms.The study is built upon five cases that all can be categorized as firms with different size and orientation.

Open access i forskningspolitiken : en undersökning av de politiska argumenten i debatten kring vetenskaplig publicering
This Master's thesis aims at pinpointing the political arguments that appear in the recent debate on scientific publication. There is a widely spread opinion that prices on digital resources are far too high, thus taking up a major part of the University libraries budget, while publishing companies make high profits. It is also a common opinion that the current publishing method does not take full advantage of the possibilities of electronic publishing. Lately a number of alternative ways of publishing have been initiated and discussed, generally referred to as open access. Open access published material is available free of charge and free of most copyright and licensing restrictions on the public internet.In this thesis the minutes from four hearings held by the UK House of Commons in the spring of 2004 are examined.
Syntaxbaserad författarigenkänning
The writing style of a particular author can be divided into many subfeatures, for example use of words, language and syntax. Focusing on the latter, this study aims to show how well syntactic information alone can attribute the correct author to a document. Syntactic information is defined as overlapping syntactic subtrees of height one (1) for all sentences of all included documents. The performance is compared to that of the previously very successful method of comparing stop word frequencies. These are words normally excluded from search engine queries, because they are present in all sorts of texts regardless of topic.
Nolltariff i kollektivtrafiken ? rättvist och/eller effektivt?
Uppsatsen behandlar frågan om huruvida en totalt skattefinansierad kollektivtrafik med nolltariff kan anses vara rättvis och effektiv. Organisationen Planka.nu:s argument för nolltariff i kollektivtrafiken analyseras med utgångspunkt i free ridning-problemet och individens betalningsvilja. Den skattefinansierade nolltariffen jämförs med marginalkostnadsprissättning och tvådelad tariff, som är två teorier om optimal prissättning av kollektiva varor. Kollektivtrafik beskrivs som en klubbvara med vissa positiva externa effekter samtidigt som varans substitut väntas generera negativa externa effekter. I uppsatsen antas den samhällsoptimala mängden kollektivtrafik vara högre än summan av alla individers individuella efterfråga p.g.a.
Tecken på liv : mänskliga spår i staden
The City is filled with signs of life. It teems with human traces waiting to be discovered. Street art of different kinds prevails behind traffic signs, on posts and electrical boxes. Personally con-structed dogs guard roundabouts all around Sweden and small gardens spire underneath window ledges. In this work I want to identify these phenomena and find out what thoughts inspired these creations.
Hur fungerar gruppen? : En studie om gymnasieelevers upplevelser av tre grupprocesser och dess påverkan på kunskapsutvecklingen
Syftet med uppsatsen har varit att undersöka elevers upplevelser av tre grupprocesser samt vilken påverkan eleverna upplever att grupprocesserna har på elevernas kunskapsutveckling. De studerade grupprocesserna är groupthink, rollagande och free-riding. Vi har valt att utföra studien genom kvalitativa intervjuer med fyra stycken gymnasieelever för att ta reda på deras upplevelser av grupparbete och grupprocesser. Resultatet av intervjuerna presenteras i kapitel 4. Analys i form av citat där vi även har reflekterat över det som sagts.
Säkerhetskulturen, organisationskulturer och katastrofer : Kvalitativ studie av tre fartygskatastrofer: Express Samina, Herald of Free Enterprise och Estonia
Forskningen om säkerhetskulturen i organisationer domineras av kvantitativa enkätstudier med fokus på hur en god säkerhetskultur skapas. Sällan studeras vilken roll säkerhetskulturen har, vare sig den är god eller dålig, i händelseförloppet mot en fullgången katastrof. Uppsatsens syfte är tredelad. För det första, kritisera hur man traditionellt konceptualiserar begreppet säkerhetskultur, för det andra, utveckla en alternativ modell för att med hjälp av haveriutredningar öka förståelsen för säkerhetskulturens roll i samband med katastrofer, för det tredje, pröva modellen empiriskt på tre fartygskatastrofer: Express Samina, Herald of Free Enterprise och Estonia. Säkerhetskulturen betraktas som diversifierad bestående av ett antal parallella kulturer, i uppsatsen benämnda som subkulturer respektive delkulturer.
Energieffektivisering av stenstadshusen - genom byggnadstekniska energisparåtgärder
The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.
