Hallsta paper mill uses large amounts of water during the pulp and paper making processes. The wastewater is treated in two separate activated sludge processes referred to as BIO 1 and BIO 2. The main aim is to reduce the organic substance content, measured as COD (Chemical Oxygen Demand) before the wastewater is released into the environment. Since the effluent produced is very rich in organic substances, the addition of nitrogen (N) and phosphorus (P) are necessary to give satisfactory treatment results. Problems with sludge bulking sometimes occur which lead to increased levels of suspended matter and nutrients in the effluent.

A new phenomenon on the Internet is the online audience response. Mentimeter is a web-based tool where you can create online polls. The users can then cast a vote and the result is shown in real time. We want to test the information visualization in Mentimeter and we base our hypothesis, that a better graph design is possible, on the work of Edward Tufte and Stephen Few. Edward Tufte is an emeritus at Yale University, where he held courses in statistical evidence and information design and has created theories about how visual information should be designed.

This report presents the development process of a mobile interface for the C2-monitor. A monitoring tool used to support the operations for the broadcasting services of Ericsson Broadcasting and Media Services (EBMS). With the support of the C2-monitor, operators can monitor hundreds of channels and services produced from EBMS. To enhance a more flexible working environment, the C2-monitor needs to be developed further to support mobile devices with a customized design to take advantage of mobile phones features and functionality. Established and well-recognized design methods and principles have been applied in the development process and user testing have been made iteratively throughout the project.

Background: Testosterone is the most important androgenic hormone in the male. Aging is closely associated with reduction of serum testosterone which can lead to reduced muscle mass, muscle strength, bone density, and depression. These symptoms may be counteracted by administration of testosterone. Objective: The purpose of this study was to examine the effects of hormone replacement in men with age-related testosterone deficiency. Method: We performed a systematic review using Randomised Controlled Trials (RCT).

There is an ongoing process where the free market within the European Union is expanding, partly through the incorporation of new member states, partly through the signing of association agreements with nearby countries and regions. When trade barriers are removed in different ways more companies consider an internationalization of the company. However, the procedure of the internationalization of companies is a rather new and unexplored area in the context of research. The focus of this study is therefore to examine how a few companies situated in Sweden, has proceeded while searching for knowledge during the internationalization process. Data has been collected through interviews that have been balanced with information from Internet and other sources.

The aim of this master thesis is to investigate how the OPACs Online Public Access Catalogue used by public libraries have adapted the features and possibilities offered by online catalogues, for the purpose of searching for fiction. This is done by comparing five OPACs to Amazon.com, an online bookstore. The questions investigated are: Have the OPACs developed from the principles of the card catalogue and adapted to the features and possibilities offered by online catalogues, when searching for fiction? Can the library catalogue provide the same features as Amazon.com, when searching for fiction? How do the OPACs use the resources that online catalogues provide when searching for fiction, compared with Amazon.com? The thesis is based on two qualitative studies. The first study presents five OPACs from different library systems and examines which features they have in common with Amazon.com.

This paper seeks to clarify the attitudes and positions of five Swedish Christiannewspapers in relation to the Suffrage reform (1907-11) and the Courtyardcrisis (1914). Furthermore I try to investigate the reasons behind their attitudesand positions. The five newspapers examined are: Göteborgs Stifts-Tidning,Församlingsbladet, Vår Lösen, Svenska Morgonbladet and Wecko-Posten.The results of my research show both convergence and divergence. Commonfor the newspapers is their criticism of the political agitation on the basisof ethics and that they all, except for Göteborgs Stifts-Tidning, recognizedemocratic principles. Divergence is evident, for example, in the reactions tothe consequences of the Courtyard crisis.I have distinguished three main factors that may help to explain the attitudesand positions of the newspapers?: nationalism versus internationalism,confessionalism and polarized political positions, and have found that the conceptof a ?Christian press? can be defended as well as put into question.

During pulp and papermaking process a huge amount of water is used. The wastewater contains a large amount of pollutants and has to be treated before it reaches the recipient. In March 2004 a new bleaching plant was started up at SCA Graphic Sundsvall AB, Ortviken?s paper mill using peroxide. The production of bleached thermo mechanical pulp and thus the load to the wastewater plant increased.

In some herds it has been observed that extremely short teats have become a problem; with a negative influence on the milking performance. The aim of this study was therefore to investigate to what degree the quality of the teats and the milk in cows with short teats is affected as compared with cows with normal teat length and furthermore if the milking performance could be improved by using a liner adapted to short teats. This study was divided in two parts. In the first part, it was examined if there were any differences between short teats and teats with normal length with reference to the milking performance, udder emptying, teat treatment, milk quality, and udder health. 11 pairs of cows were used and in each pair of cows one cow had teats shorter than 40 mm while the other cow had teats longer than 50 mm.

In Sweden there are currently two separate guidelines you may use whenperforming calculations on frameworks, BKR and the Eurocodes. Although at theend of 2010 you are not allowed to use BKR any longer and only the Eurocodeswill be viable. The aim of this thesis is to explain how the Eurocodes and EKS work and alsohow they compare to the current guideline BKR. Similarities and differencesbetween these guidelines are also discussed so that the reader will get a betterunderstanding of how the Eurocodes are applied. The areas discussed are asfollows:Principles and adviceSafety ClassesSymbols and IndexesLifespanLoads and partial coefficientThe thesis also deals with the impact that this transition into a new guideline willhave on corporations, guideline costs, education and computer software. As anexample a rough estimate on what costs this transition will create on a companywith 20 employees is also included. Calculations have been performed in order to investigate how the design valuesdiffer between the two guidelines, the Eurocodes and BKR.

The aim of these two studies was to investigate the possible physiological, behavioural and emotional changes that appear after human-horse interactions and also to find an explanation to why they occur. One aspect that is discussed is whether the wellbeing of humans can be coupled to interacting with horses and of how the animals respond to the interaction. The first study was performed on 9 horses and their owners, both parts being subjects to registrations during 4 different interaction treatments. The second study was performed on 6 horses with registrations only being performed on the horses during 2 different treatments. Nine horses underwent 3 different treatments all performed by their owners (H = stroking of the horses forehead, B = brushing and M = stimulation of the withers) in addition to a control round (K). Each treatment lasted for 4 minutes but observations were performed until after 45 minutes from start.

In order to achieve comparability, which is one of the fundamental principles of accounting, companies should be consistent concerning the accounting policies they use. Only under certain circumstances changes in accounting policies are allowed, and when there is a change in accounting policies, it is important that the change is reported in a way that assures that the financial reports still achieve comparability. The purpose of this thesis is to establish which rules and recommendations about changes in accounting policies that exist in Swedish and German law and what their meaning is. Further, the purpose is to compare these rules and recommendations and discuss their differences and similarities, advantages and disadvantages. Since publicly traded European companies will be obliged to prepare their consolidated accounts in conformity with International Accounting Standards (IAS) from 2005, I also describe the content of IAS 8 which deals with changes in accounting policies, and discuss what the consequences of this transition might be for Swedish and German publicly traded companies considering changes in accounting policies.

The purpose of this study was to evaluate the different substrates that enter the digestion on Sundet wastewater treatment plant for production of biogas.This work have done an analysis of data about the biogasproduction from January 2012 to feburari 2013, this showed that the food substrates has a greater gas production than internal sludge.Through laboratory test the VS, TS and COD values for all the substrates used in the biogas production could be determinded. But the COD-method was less optimal for analysis of fat and food, therefore it optimized the method for fat but due to time constraints, this could not be done on the food substrates..

The purpose of this Masters thesis is to investigate how actors involved in a municipal's adult education view students access to information- and library resources. The adult education in the municipal is on contract which means that there are several different actors involved in the realization of the adult education. The raised questions in this study deals with; libraries role within adult education, students needs for becoming information literate and where responsibilities for students access to libraries lies. We used a qualitative method which includes interviews with two principles, a controller, three pedagogues and a librarian. The empirical data is analysed against taxonomies and categories which originates from the theories of David Loertscher and Christine Bruce.

Collaboration is a form of organization on the rise in Sweden. For health care, it is ofinterest to collaborate with industry to ensure that needs for specialist education andtraining are met and that products developed meet the relevant requirements.Conversely, industry actors have an interest to have a close collaboration with healthcare in order to gain insight into customer needs, provide information about theirproducts and to test products in development.The starting point of this study is an agreement and regulatory framework for formsof collaboration between public health care in Sweden in general and thepharmaceutical industry, the medical device industry and the laboratory technologyindustry. The research questions concerns how this agreement has evolved and theprocess surrounding its emergence may contribute to knowledge about collaborationas a form of organization and the relationship to concepts such as legitimacy,corruption and institutional theory.By tracking the emergence of the current regulatory framework genealogicalthroughout history, the study uncovers how the agreements have played a role in andcontributed to the legitimization and institutionalization of collaboration practices andhow crises have changed the shape of the practices. A theoretical treatment ofrelevant concepts such as legitimacy, institutionalization of practices, corruption andstigmatization of organizations form the basis for an interpretation and analysis of theprocess.The conclusions of the examination of the historical process that led to the currentagreements contribute to empirical knowledge of how crises and stigma affect thelegitimacy of collaboration practices and how the repair of legitimacy can be donesuccessfully after a crisis. The treatment of the empirical material is also a historicalsource for the development of ethics agreements between public health care andpharmaceutical industry and the medical industry in Sweden..
