The Bovine respiratory syncytial virus (BRSV) causes bronchiolitis and interstitial pneumonia, predominantly in calves, and is a major cause of bovine respiratory disease worldwide. In humans, BRSV is paralleled by the closely related Human respiratory syncytial virus (HRSV), an important cause of respiratory disease, most severe in infants.The clinical signs and pathology during RSV infection is caused, not only by the direct effects of viral replication, but also by the response of the host immune system. The immunopathology of RSV has long obfuscated our understanding of the disease, and development of effective treatment and vaccines will be very difficult until greater knowledge is gained.One of the components of the immune system that has come into focus in RSV research the last few years, is the Toll-like receptor 4 (TLR4). The TLR4 receptor is well known as the receptor that binds lipopolysaccaride (LPS), and initiates the host response to bacterial infection. Recently, it has been shown that the fusion protein of RSV also interacts with, and up-regulates the expression of, the TLR4 receptor.

This paper describes how radiation affects the body, the somatic and genetic effect that can occure in exposure of ionizing radiation and how to protect yourself against it. How radiation affects the cells and why you can get cancer if you get exposed of a large amount of radiation is mentioned. Research after a threshold is mentioned and what Sweden does today to improve the radiation protection by laws and regulations. Explaining the atom, what radiation is and how the ionizing radation interacts with the atom. How backscatter affect the picture and the workers and how to protect yourself from backscatter is mentioned. Radiation doses, dosimetry and rules for those who practise radiation is shortly described..

This report contains a risk analysis of transportation of dangerous goods in Kalmar. The analysis is based on quantitative data and an evaluation of the risks based on both the probability of occurring accidents as well as the consequences of those. The risks are presented as both individual and societal risks..

This piece of work develops a solution that automates protection against software keystroke loggers. Keystroke loggers can be used illegally to register a user's keystrokes and in that way acquire sensitive information. The solution was tested on two different networks and the efficiency was measured. The network represents an enterprise network that uses the operating system Windows along with the directory service Active Directory. A script was developed to solve the automation matter.

The aim of this thesis is to study the situation of minorities in Slovakia before and after the EU-membership and if EU has played a role in the situation. Also the criteria for becoming a member and other treaties regarding protection of minorities between European institutions and the accession/member states are studied. With the help of i.e. literature, relevant internet pages and yearly studies of EU, the conclusion has been made that Slovakia has made an immense change in the state?s legislation when it comes to minorities and their fundamental rights, but that changes need to be made in attitudes as well.

Nature conservation agreement (NCA) is a way to voluntarily protect and manage nature for limited time-periods. The agreement is settled between the government and a landowner. All public authorities can represent the government but it is only the Swedish Forest Administration who does that regularly (because it is the only authority with economic resources for that purpose). Therefore, NCAs are almost only used to protect forested nature. The government agencies have experienced NCAs for about ten years and it is now time to examine how they are applied in the forests. This study is based on a computerized questionnaire to the persons responsible for the LEKO-projekt.

A group of companies that only recently has caught the attention of Swedish designers, enterprises and media are the so -called "furniture pirates". In Sweden it?s mainly two companies that have ended up in the spotlight. The online stores Ikon M and Designers Revolt are two companies which currently sell replicas of famous Swedish and foreign designers. Although the designs sold are copyright protected in Sweden, and most other European countries, the right holders can only stand by and watch as more or less exact copies are sold for a fraction of the price of the originals.The business model - to exploit the EU?s free movement of goods and the UK's short term of copyright protection in matter of mass-produced art (industrial design) - has proven successful for the companies that practice it.

Due to the requirement for reduced use of insecticides and the lack of competitive mechanical plant protection, you need a scarification with good result. This is often no problem to perform in normal terrain without technical barriers. However, in difficult terrain with large number of rocks and steep slopes, the result would be worse. The purpose of the study is, that in these areas with difficult terrain, to find out the scarified areas quality, describe the non-scarified areas conditions and find out where the limit is for the use of a traditional disc trencher. Findings indicate that there are usually not the machine that is the limit, but the driver of this.

ESAB is a world leader in production of welding consumables and equipment. The company manufactures, among other things, welding electrodes. A roller straightening unit is used in the cutting process to straighten the wire, which the welding electrode consists of, by adjusting some of the rollers during operation. According to ESAB?s standard and the European machinery directives, moving parts of machinery, such as rollers of the roller straightening unit, must be out of the operator?s reach.

Att försörja sig som streamingpersonlighet på Internet är något som vuxit explosionsartatpå senare tid. Detta leder också till att man blir ett tydligt mål för attacker. Detta arbetehar belyst den problematik som DDoS-attacker skapar när de riktas mot hemanvändare.Olika lösningar på detta problem gås igenom och analyseras. Tester har utförts för attbelysa enkelheten i attacken samt hur den påverkar hemanvändares hårdvara. Testernahar resulterat i att VPN är en kompetent lösning men innehåller även nackdelar..

This report is an evaluation of the cooperation between the rescue command centre and the POSOM-groups (?Psychological and social support?) after the Tsunami catastrophe in December, 2004. The report describes the interaction between these two municipal administrations, what services the rescue command centre provided and how they gathered information. Finally the author suggests different solutions to how the collaboration within these different municipal administrations can be increased and improved in future times of crisis..

This paper describes the work done trying to diminish the noise present in the signal from an IR-detector. The project was aiming towards two different kinds of applications; heat protection and presence detection. The hypothesis was that the signal-noise ratio would decrease if a filter and a proper installation were used for the detector. Some experiments were executed to determine what kind of filter were the most suitable for each application and how these could be installed. After executing the experiments and evaluate the results we recommend to use a specific filter for each application.

Historically transformers with system earth equipment have been modeled as open circuits in zero sequence. This approximation has been satisfying, but lately it has been discovered that equipment on one side of the transformer have responded to faults that occurred at the other side. Most of these problems took place when the majority of the system on the secondary side of the transformer contained cables. These findings have led to questioning whether or not the former model of the transformer in zero sequence is correct. This report investigates if it is necessary to represent the transformer in zero sequence in another way than it is usually done today.
