Today the Internet is used more and more as a transportation for information. Much of the information is confidential and should not be read by those not privileged. To protect the information from unauthorized access cryptography can be applied. The cryptography algorithms in use today all have their pros and cons. They are therefore suited for different applications.

BACKGROUND Until 1988, it was forbidden to neuter male dogs in Sweden without a veterinary medical cause, so there is clearly no long tradition of this procedure in healthy dogs. According to the website of The Swedish Kennel Club (SKK), February 11, 2011, there has been an increase of castrated male dogs in Sweden. They see this increase as worrying, especially in cases of the less common breeds, where it is most important to maintain the gene pool. The SKK expresses concern that castration is used as a tool to influence the personality of dogs, instead of training and education of the dog. They write that castration should be preceded by a discussion initiated by the veterinarian, where the pros and cons of castration are weighed against each other.

AbstractIn urban societies people spend more and more time indoors, which put great demands on the indoor environment. If the ventilation is to manage the removal of unwanted substances in the indoor air, a good mixing of the air is required. The question arises that, whether the buoyancy forces will counteract a good mixing of the indoor air or not?This report aims to clear up the difficulties whether you need to consider the buoyancy forces or not, when adjusting a ventilation unit. For studying the indoor mixing of the air a two dimensional model is constructed in COMSOL Multiphysics.

The contribution of biofuels to the total consumption of energy in Sweden must increase to 49 % in order to meet the goals for the year 2020 set by the European Union. In order to do so, improved information systems are needed to support the business processes within delivery scheduling between customers and suppliers.Enterprise Architecture (EA) is a concept to enable the alignment of Business processes and Information Systems. EA is the framework for the architectures of business, information and applications. With a comprehensive view of the architectures, an Information System aligned with the Business processes can be enabled. The first step in the development of an Information System is documenting the business processes.The goal of this study is to clarify a generic sequence of activities performed within the delivery scheduling process and the information needed to perform the activities.Data for the study was collected through qualitative interviews, first through a meeting with the respondent and after that a following telephone interview with in total 5 suppliers and 6 customers of biofuels.

The rapid change within digital medias has increased the possibilities to make information accessible through network. Therefore the European Union EU considers a harmonization within the Union, in order to strengthen the rights of the originator. The purpose of this thesis is to evaluate how the EUs directive 2001/29/EG regarding copyright is to be implemented into Swedish legislation and assess the common opinion in the public libraries on this matter. The basic methodology of this thesis is a democratic perspective, concerning the public libraries democratic role and the right of the citizens to have access to information. The thesis first part is a study of documents.

On Nasdaq OMX Nordic Stockholm there has been a large increase in issues of preferred stocks since the financial crisis 2008. Aiming to explain whether preferred stocks have most of their characteristics relating to debt or equity, we answer four sub questions. Do all preferred stocks share the same features, or do they differ from each other? Our population is similar in characteristics, except for the preferred stock of Swedbank which is convertible and deviates when it comes to participation in dividends - instead of convertible the others are limited and redeemable. Further, the second sub question treats preferred stock in relation to the common stock quantitatively, in market data.

The focus of this work is to study whether public libraries should offer their patrons unlimited access to the Internet, or restrict which sites they can visit. The most common tool used to limit Internet access is filtering software. The author has administered four interviews with public librarians working in libraries in Southern Sweden. All four librarians had different opinions about restricting Internet access. The most important question asked was if they had chosen to use filtering, and the reasons for their decision.

Inledning: Tidig utskrivning från sjukhuset efter hjärtkirurgi förutsätter att patienterna ska kunna hantera mycket av den postoperativa återhämtningen på egen hand. Det är därför viktigt att sjukvårdspersonalen i helhetssynen på patienten har förståelse för den postoperativa återhämtningsprocessen. Sjuksköterskan har en viktig roll när det gäller patientinformationen och hon kan genom en tillräcklig information hjälpa och stödja patienten under återhämtningsprocessen.Syftet: Syftet med denna litteraturgenomgång är att belysa vilken betydelse patientinformation har för återhämtningen efter hjärtkirurgi.Metod: Studien är en litteraturgenomgång som bygger på 12 vetenskapliga artiklar. Litteratursökning genomfördes i de elektroniska databaserna Pubmed och Cinahl mellan 30 januari till 30 mars 2011.Resultat: Det framkom tre teman i resultatdelen; behovet av information, innehållet i informationen samt att informationen ska vara individanpassad.Konklusion: Patienterna hade behov av information under hela vårdtiden och även under återhämtningen i hemmet. De hade önskemål om att få information om den normala läkningsprocessen under återhämtningen, inklusive den psykosociala funktionen och eventuella komplikationer.

Denna uppsats behandlar värdering av förvaltningsfastigheter till verkligt värde enligt IASB:s standarder IAS/IFRS. Vår undersökning syftar till att utreda vilken information som finns tillgänglig för svenska fastighetsbolags mindre aktieägare i tryckt press och i årsredovisningarna, avseende värdering till verkligt värde. Genom att studera årsredovisningarna för sju bolag och artiklar publicerade i sex tidningar och tidskrifter har vi kommit fram till slutsatserna att:?en mindre aktieägare måste vara aktiv i sitt sökande för att hitta den information som finns,?artiklar som behandlar ämnet inte har publicerats i större omfattning,?den information som lämnas ofta är komplicerad och svår att förstå..

The aim of this thesis is to describe passage retrieval (PR), with basis in results from various empirical experiments, and to critically investigate different approaches in PR. The main questions to be answered in the thesis are: (1) What characterizes PR? (2) What approaches have been proposed? (3) How well do the approaches work in experimental information retrieval (IR)? PR is a research topic in information retrieval, which instead of retrieving the fulltext of documents, that can lead to information overload for the user, tries to retrieve the most relevant passages in the documents. This technique was investigated studying a number of central articles in the research field. PR can be divided into three different types of approaches based on the segmentation of the documents.

This Masters' thesis is a study on the information behaviour of hospital personnel at the University Hospital in Lund, Sweden. A questionnaire was distributed to 301 nurses and physicians working in the intensive care unit, the population was reduced to 244 persons. The response rate was 52%, i.e. 125 questionnaires were completed. Nurses constituted 68 % of the population.

Workplace accidents in Sweden have in recent years increased. Companies are at the same time putting a greater emphasis on preventing accidents and inform about safety and risks. Therefore there is a need to know how to visualize this safety information. This study is based on a part of a project proposed by the industrial company AB Wahlquists Verkstäder, in which they want to visualize their safety information for new employees and existing staff, and also for temporary contractors and apprentices. The purpose of this study is to see what is required of the visualization of safety information and what guidelines that should be followed.

Social media on the Web has become more common over the last decade and in recent years it has grown immensely. The social media with the highest amount of members is Facebook, where not only private persons are found - companies started to establish their profiles on the network in 2006. However, little is known about how these companies succeed and reach their audience with information dissemination and interact with them. The aim of this study is to contribute with information to local companies on how they can manage to maintain their activity with different approaches and strategies. This study examines how three different local companies chooses to spread information and maintain relationships with their members on Facebook.

The aim of the present thesis is to examine discourses about teaching information seeking in upper secondary school teachers. The main questions are: (1) What different interpretative repertoires can be identified among teachers talking about teaching information seeking in relation to students? problem-based tasks? (2) How are these repertoires constructed and what functions can be observed? The theoretical framework is discursive psychology. Two teacher teams from two different upper secondary schools in the Gothenburg area participated in focus group interviews. Group A consisted of four teachers from the Individual Programme and group B of seven teachers from the Social Science Programme.

This study is based on my work as a teacher of Swedish language and literature to upper secondary school students, and my interest in developing the teaching of literature by using both new criticism theories and theories of literary perception focusing on reader response. The purpose of the study is to examine the learning process in trying to develop literary competence and to find out how to describe the competence shown by the students. My starting-point is a discussion about literary competence and the theory and model of literary competence by Örjan Torell. In examining literary competence, by how students use their constitutional competence as well as performance and literary transfer competences, Torell´s model shows the possibility and the need for both knowledge of literature and personal reception by focusing on the dialogue between author and reader.The method is qualitative and the empirics are material collected in one senior high school class in the Social Science programme during their second and third year. The material contains written reading logs, written answers to tasks and transcribed recordings of discussions of literature.The analysis shows a variety among the literary competence shown and developed by the students and points to the complexity of understanding the concept of literary competence.
