The systems environments of today are often distributed and heterogeneous. These kind of systems have several advantages but also disadvantages. One problem is how to keep them secure.The security problems in these environments are mainly due to the communication between the connected computers. It is relatively easy to tap these communication channels from information. There is also a need for the possibility to secure these channels from modification of sent information and to be able to verify the sender and receiver of information in a secure manner.

The aim of this study is to find out if the former students think that they have made use of the courses they have taken at the Natural Resource Use Programme specialised in Animal Husbandry at Lillerudsgymnasiet or if the courses should be exchanged. In the study it is assumed that a course can be useful professionally, for further studies and in private life.The main questions are: Have the former students made use of the courses they took at the Natural Resource Use Programme specialised in Animal Husbandry at Lillerudsgymnasiet? Was it the right decision to replace the course Horses?I have sent a questionnaire to all the students who graduated between 2003 and 2007. Out of 107 questionnaires I received 66 replies (62 %). All students have studied the same mandatory courses but different eligible courses.

This Masters thesis is concerned with the complex planning process of setting up a citizen bureau in a public library. The aim is to find out how citizen bureaux are designed and to suggest a simplified model of strategic planning. The planning process is studied from a business perspective in the library context, and this perspective is also used to study citizen bureaux and their written plans elsewhere. A combination of qualitative methods are used: observations, focus group discussions and interviews. Observations in the public library showed a great need for an environmental analysis as well as structure to the planning process.

The aim of this thesis is to mediate to the reader an image of Chinese classification systems and in what way the methods of classification have progressed during time. The tradition of classification in China is very old and dates back more than two thousand years, but it wasnt until the downfall of the dynastic era in the beginning of the 20th century, that Chinese libraries and methods of classification were modernized. This thesis also identifies the development of Chinese librarianship which is of old age since Chinese literature stretches three thousand years back. The main question is in what way the values of three different philosophies are reflected in five classification systems compiled between 1953-1975. The three philosophies are Daoism, Confucianism and Maoism/Mao Zedong Thought.

Urban densification as a planning strategy is of interest in the planning context of today. It is also seen as a part of the sustainable development. Urban densification as a concept is commonly used in the discussion of a sustainable development. Thus, the question about urban densification is an important challenge in the current planning context. A deeper understanding of the process which urban densification has developed from is necessary, since planners then will be more able to manage this challenge.

The following thesis will examine how a smaller library manages the prioritization of media between Swedish and 'minority language'. We are also interested in the challenges and problems that can occur in such work, as well as how the librarians think about their role in the integration process. We have studied this through several qualitative interviews with librarians as well as earlier related research. The results show that librarians display a high propensity of appreciation related to working with minority languages and consider this an important aspect of their profession ? they fully ingratiate and accept the importance of helping the immigrant population in learning Swedish.

Kulturmiljöns roll i planeringen utreds i detta examensarbete där begreppen och dess tillämpningar förklaras och teoretiska och metodiska aspekter presenteras. Analysresultatet används för att åskådliggöra nådda slutsatser som bildar underlag för den avslutade delen av arbetet som utgörs av att pröva resultaten praktiskt. Teori- och metoddelarna visar på hur kulturmiljöer är karaktärsskapande och ger identitet till platsen. Vilket på så sätt gör dem till en resurs för framtiden. Då kulturmiljövärden tas tillvara genom hänsyn i planeringen kan de berika och vara en tillgång för människor och samhälle, de bildar en av de grundläggande utgångspunkterna för olika planerade förändringar. Det krävs att dessa värden tidigt inryms i planeringsprocessen samt att flera perspektiv får komma fram för att de ska bilda en värdefull utgångspunkt.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

The purpose of this study was, if possible, to find a housing system for growing bulls that was as optimal as possible for the animal welfare. In order to select housing systems you must take into account the size of the group, body weight and the type of floor. Seven of the international most common housing systems were compared, straw bedding, deep straw bedding, sliding straw bedding, concrete slatted floor, rubber coated slatted floor, cubicles and feeding cubicles. Studies that have examined the proportion of tail, claw and leg injuries and the presence of unnatural behavior in the different systems. In summary, all studies showed that soft underlay were beneficial for the animals in terms of the proportion of bone lesions and swellings.

The aim of this master thesis was to find out about librarians opinions of childrens libraries on the Internet, if it is a resource to reach children. Qualitative interviews were conducted with three librarians who had participated in the construction and development of childrens libraries on the Internet. IT and the Internet play an important role in childrens lives and children are using it to a greater extent. Libraries have begun to integrate IT and Internet into their services and are offering service on the Internet. The public library websites are usually for grown-ups and very few are directed to children.

This report is written in cooperation with Eskilstuna municipality public administration for urban planning. The reports purpose is to look into how other public authorities carry out public purchase of consultants and entrepreneurs in the urban planning area. The goal is to come up with suggestions of how Eskilstuna municipality public administration for urban planning can improve its purchasing process in this field in order to minimize the risk where a consultant or entrepreneur files an appeal against the decision of awarding a contract to another rival. The appeal can be filed to the county administrative court.The public administration for urban planning can do its purchases through the model of "lowest price" or "economically most favorable" for them. When using "economically most favorable", the department can value a number of soft parameters by giving them points and the offer which gets most points can be rewarded the right to sign a contract.

Preschool has a long tradition of using picture books, both as entertainment and as a resource for educational activities. In science there are two main application areas. The first one is science concepts and the second is to teach basic science process skills. These skills, observing, communicating, inferring, classifying, measuring and predicting reflects the methods used by scientists. Picture books potential to put science concepts and activities that promote the use of science process skills in a meaningful context, recommends using picture books for this purpose.
