This report is an outcome of a master degree project at Linköpings University in co-operation with Micronic Laser Systems AB. The purpose with this master degree project was to investigate how to implement a receiver in a data transfer system. The system consists of several data channels, where every channel consists of three parts: driver, transmission lines and receiver. The driver send low amplitude differential signals via the transmission lines to the receiver that amplifies and converts it to a single-ended signal. The receiver has to be fast and be able to feed an output signal with high voltage swing.

Tolerance and resistance are two different defence mechanisms within the immune system that differ from each other in many ways: However it is not clear which of the two is the most advantageous in dairy production. Resistance is described as the ability to fight a pathogen in a host. Tolerance is, on the other hand, not aggressive to the pathogen per se, but rather protects the host and its tissues. Furthermore tolerance rather offsets the toxin from, for example, a parasite whilst resistance offsets the parasite itself. Resistance is however disease specific, which means breeding for a large number of diseases is needed in order to make resistance worth the cost for the host.

The present study aimed to replicate Tversky & Kahneman's' survey of 1981 The Asian Disease Problem. A survey was conducted on the Internet (N = 200). An identical problem was added, yet with The Swine Flu as the disease. This was done to be able to investigate if there are any order effects, and also if it matters whether the mentioned disease is fictional or real. The results show the same results as Tversky & Kahneman already noted; positively and negatively framed problems generate different responses from the participants.

A group of diseases that affect the dog?s sight is progressive retinal atrophy (PRA) a disease that means that the photoreceptors in the retina of the eye either not develop normally or undergo degeneration and thereby causes vision loss and blindness. The disease affects many different breeds and is inherited. What have been shown is that it is different genes that had become mutated in the different breeds, this conclude that despite similar clinical symptoms, the underlying reason could be different. Also the genes that are mutated in dogs and give rise to diseases also exists in humans.

A central question is what view of communication is dominating in a municipality in the southern part of Sweden. The study deals with communication theory from two different perspectives; the view of transmission and the view of creation of meaning. Falkheimer and Heide (2003) claim that the view of transmission is one-way communication where the receivers apprehend passivly. In the view of creation of meaning the goal is to develop and strengthen the common notion that exists in a group. Empirical studies were done, that consisted of qualitative interviews with politicians, directors of the municipality, and principals from three childcare and school areas, and also from one upper secondary school.

Plasmacytos är en kronisk, persistent och progressiv viros med hög dödlighet och allvarliga reproduktionsproblem som ofta kallas Aleutian disease (AD). Sjukdomen drabbar i huvudsak mink och är ett stort problem på minkfarmer, men kan även drabba vilda mård- och hunddjur. Undersökningar för att kartlägga utbredningen av plasmacytos i den vilda minkpopulationen har inte tidigare gjorts i Sverige. Nittio minkar från hela Sverige obducerades och provtogs avseende antikroppar mot ADV (Aleutian disease virus) och av dessa var 41 stycken (46%) seropositiva, vilket är en hög siffra jämfört med våra grannländer. Infektionen visade sig vara spridd över hela Sverige, men det förelåg en tydlig säsongsvariation där en högre andel seropositiva minkar påträffades på våren.

Background: Inflammatory bowel disease (IBD) includes Crohn´s disease (CD) and ulcerative colitis (UK). The diseases are chronic and have a pattern of relapses interspersed with relatively symptom-free periods. Common symptoms during relapse are diarrhea, abdominal pain and weight loss. Since you have IBD for life it is important to find ways to relate to and cope with the disease. In that process a nurse can be of great help.Aim: The purpose of this literature review was to increase the understanding of how adult patients with inflammatory bowel disease experience their daily lives.  Method: The method used was a literature review.

Animals in zoos live in small enclosed areas. If a pathogen is introduced to the zoo, the animals are extremely vulnerable. The highest risk of introducing new pathogens occurs when new animals are introduced to the collection. Therefore it is essential that zoos have a protocol in place for disease prevention. This review has studied literature on the subject of disease prevention protocols when translocating animals between zoos.

The objectives of this study was to examine the prevalence of hypertrophic cardiomyopathy in a family of British Shorthaircats to determine the mode of inheritance and to investigate if the disease was associated with a mutation in myosin binding proteinC (MyBPC3). The family comprised 28 cats, seven male and 21 females. The cats underwent a physical examination, including cardiac auscultation, and an ultrasound examination. Blood was collected for DNA- analysis. The blodsamples were sent in a buffer solution to Kathryn Meurs, Washington State University, USA for analysis, where the genes coding for MyBPC, Troponin I and T were characterized using microsequencing technique. Out of the 28 cats, 8 were diagnosed with HCM, 2 were diagnosed with congenital heart disease but had no evidence of HCM.

Chronic obstructive pulmonary disease (COPD) is a chronic lung disease. The disease is the fourth leading cause of death and more than 5 percent of the adult population worldwide is affected.The aim of this study was to investigate the association between periodontitis and COPD.Search for material for the literature review was done in the medical database PubMed where the keywords were: "Chronic obstructive pulmonary disease" and "Periodontal health or periodontal disease". The result is based on twelve studies that were extracted and analyzed. The studies have investigated pocket depth, attachment loss, plaque index, bleeding on probing and bone loss. Ten studies compared a COPD group with a healthy control group, one study compared two COPD groups and one study examined a COPD group and a group with other lung diseases.Most studies found that people with COPD had a higher incidence of pocket depth, attachment loss, plaque index, bleeding on probing and bone loss.

This report explains the need to develop a configuration manager that handles transmission equipment which exists in the Swedish Defence telecommunications network. The configuration module will display the configurations and compatibility among the equipment and their software which are all part of the network.Also included in this report are tools, methods and results for the development of a prototype for the configuration manager. The prototype consists fundamentally of a database assisted by a user friendly website.The transmission equipment handles a lot of important transmission of information and is in the hands of a department of SAAB, OFGCA, by orders from the Swedish Defence Materiel Administration (FMV). Within the work included in this order exists a continuous update of both software and hardware which the equipment consists of. Therefore it?s highly important that there is a monitoring of which of the software and hardware is compatible with one another, ensuring that the functions of the system work properly.The consistent updating has resulted in compatibility issues between components and because of this, a need for a configuration manager has arisen..

Aim: The aim of this study was to investigate the quality of the social network in regard to young adults, with psychological disorders, and their possibilities to be open about their disease. In addition the study aimed at identifying possible causes to perceived difficulties by young adults to talk about their disease. Method: The survey was a quantitative study with descriptive design. The data was collected using a study-specific questionnaire on a clinic for young adults with psychological disorders, between 18 and 25 years of age. Out of 123 potential participants 79 (64 %) answered the questionnaire, of which two were excluded because they did not see themselves as suffering from mental illness. Results: The results showed that the participants of the study stated that they had a social network and the majority (90%, n=69) considered they had someone to talk to about their disease, but most of them wanted to be more open about their illness.However, the majority had some form of difficulty to talk about their disease with their social network. The most common specified causes were to feel ashamed of their disease and that the mentally ill persons did not think they would be properly understood.Almost the half of the participant experienced that they had some form of difficulty to be open about their mental disorder in front of health professionals and the most common specified causes was that the participant did not thought that they would be properly  understood  or that they did not felt confidence before the health professionals. Conclusion: Young adults with psychological disease have difficulty to be open about their disease, partly because of stigma.

In using a qualitative method have I interviewed six women and six men taking care of their wives respectively husbands suffering from physical disease, disfunction or demental disease. The purpose was to find out whether male and female caretakers were differently influenced in their situation, relationship and in their partners, when they became caretakers of their spouse, depending on what the partner suffered from.The results showed that, when a husband or wife was hit by disease or disfunction, the caretaker was influenced both in the partners situation, the relationship and the role towards the partner. The couple still lived in a close relationship and could communicate. For the carers spouse suffered from a demental disease, there was no communication as before or possibility to remember. The carers also felt the loss of community, nearness and sympathy.

Introduction: We are facing an aging population, which means that the incidence of age related diseases, such as Alzheimer's disease, are expected to increase. In the current situation there is no cure for the disease, whereupon it is important to develop preventive strategies. Objective: To examine the association between Alzheimer's disease and physical activity. Method: A systematic literature search was done to identify the current state of knowledge from the year 2006 onwards. The reason for this limitation was that the SBU commissioned a systematic literature review in 2006, where the relationship between physical activity and Alzheimer's disease could not be determined.

Cardiovascular disease is the leading cause of death in the Western world. For persons who have had a myocardial infarction the following rehabilitation and the group training, which is a part of this, are very important. The cardiac rehabilitation is designed to limit the physiological and psychological effects of cardiovascular disease. Purpose: This study aimed to examine how patients with cardiovascular disease experienced group training in relation to the International Classification of Function, Disability and Health, ICF. Method: A qualitative interview study was performed according to Malterud, inspired by the Grounded Theory method.
