The heuristic methods used by the anti-trojan application TrojanHunter have been evaluated. The evaluation shows that the heuristic scan engine of TrojanHunter has a very good detection ratio and that the detection ratio can be even further improved by implementing the suggested improvements, the most important of which is a white list to avoid misidentifying files that are known not to be trojans..

Sahlgrenska Academyat University of GothenburgDepartment of internal medicine and clinical nutritionAbstractTitle: Can supplementation with vitamin E improve cognitive function in Alzheimer?s disease?Author: Malin Andersson and Elin LöfqvistSupervisor: Elisabet RothenbergExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2012-04-11Background: Alzheimer?s disease (AD) is the most common form of dementia. As the average life expectancy rises the prevalence increases. The disease leads to gradual deterioration of cognitive functions. A recent Cochrane review describes how several studies demonstrate an increased oxidative damage in the brain in those with AD.

Having different kinds of literature is an important part of the education in school and schoolbooks, in shape of reading-books, are common in the first year of primary school. The texts pupils encounter in school are important for how they form their identity and thoughts about what is right or wrong and what is natural or unnatural. People of other ethnicity than Swedish, or with another skin colour than white, have often in the past been portrayed negatively in reading-books as if they are of less worth. According to the Curriculum for the Compulsory School System (Lpo94) the school shall act for understanding of all people and every person?s equal value.The study analyses how ethnicity is portrayed in reading-books for pupils in the first year of primary school.

During the last two hundred years many wetlands and streams in Sweden have been lowered to provide land for agriculture and forestry. Some of the coastal wetlands and streams probably served as spawning sites for certain species of fish in the Baltic Sea, but the present situation is not well known. As standardized methods to monitor fish in running waters are carried out during late summer or autumn, there is a need for methods to sample spring-spawning fish in these streams.The aim of this study was to survey the lower kilometer stretch of Hammerstaån in Stockholm, to investigate the extent to which the stream is used by spring-spawning fish. Furthermore, the study aims to evaluate a new type of survey fishing gill net calledströmöversiktsnät (SÖN). This was done by comparing the catch of fish by SÖN with that of fyke nets.

Canine parvovirus is associated with two disorders: enteritis, which is common, and myocarditis, which is rare. Prominent clinical signs of parvovirus enteritis are vomiting, diarrhea and rapid dehydration. Canine parvovirus type 2 (CPV-2) is very contagious. When CPV-2 first emerged it had high rates of mortality, but later studies have shown that most infections are self-limiting and do not require veterinary care. Mortality rates vary greatly, and therefore it is important to determine risk factors for developing severe canine parvovirus enteritis.

Knowledge organization is perceived as a central, constituting activity defining the notion of libraries. Critique calling for a new theoretical foundation voiced by active researchers within library and information science concerning the current knowledge organization has been utilized as a point of departure. Specifications concerning a new theoretical foundation implied by these critiques are considered within this thesis and theory found in The Order of Things by Michel Foucault proposed as an alternative theory for understanding knowledge organization as a human science where meaning, value and representation, by which the ordering of things is possible, is acknowledged as a result of human activity and history. Thus meaning, value and representation must be perceived as dynamic. An example of implementation of the proposed theory has been achieved by the use of bibliometrics.

I Upplands Väsby utanför Stockholm tillverkar Kraft Foods bland annat choklad under varumärket Marabou. Vid anläggningen finns en Pralin Line som är en automatiserad produktionslinje för tillverkning av chokladpraliner i ask. Under en tid har Pralin Line inte kunnat motsvara förväntningarna och har inte haft den linjeeffektivitet man eftersträvar. Som ett led i detta har ett projekt initierats för att öka effektiviteten vid Pralin Line. En del i projektet är detta examensjobb som syftar till att utveckla det förebyggande underhållet vid Pralin Line.

Health and fitness are two controversial and not easily defined topics that affect people in our modern society every day. We believe that we can find a link between individualism, globalization and the stress concerning weight and appearance ideals. Our bodies have turned into a popular subject for the media, and there is no indication that the interest will decline. As the world gets more artificial, "natural" ideals are getting more attention, such as the concept of a strong and healthy body. But there is also a downside, for example with health issues such as cardiovascular disease increasing following the birth of high-fat diets.

Mammary tumors are the most frequent type of tumors in bitches in Sweden. Many studies have been published concerning mammary tumors, but there is still much to be learned about this disease. One has, since some time ago, had the knowledge that addition to or removal of methyl groups to genes can inhibit or activate gene-expression. Methylation and demethylation is a normal phenomenon in the body and it is essential for the development and survival of the individual. The risk of developing a tumor disease is increased if the global methylationstatus is changed; if oncogenes demethylates (activates) or if tumor suppressor genes methylates (inactivates). In the human medicine one has seen that there are differences in methylationstatus between different tumors. In this study tumor and normal tissue from ten dogs were examined with regard to methylationstatus.

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.

The lions at Kolmårdens zoo are vaccinated against Feline Panleukopenivirus (FPV). In 1994 there was an outbreak among the lions at the zoo of FPV disease. A retrospective study has been made to measure the antibodytiters in vaccinated lions and lions that lived during the outbreak. An ImmunoPeroxidase Monolayer Assay (IPMA) was used to analyze the titers in the sera from the lions. Lions were divided into five groups. Group 1, 2 and 3 contained lions vaccinated one, two and three times respectively (a total of 40 animals). The lions of Group 4 were born in 2004 (six lioncubs) and were vaccinated according to different regimes and the changes in antibodytiters were followed as respose to vaccination during the spring 2005.

Disturbances, such as fire and wind, are important for saproxylic beetles (= beetles depending on decaying wood) to gain substrate in boreal forests. Clear-cutting is an example of a man-made disturbance. Measures such as prescribed burning have been made to resemble natural disturbances. The aim of this study was to see which clear-cut characteristics are important for the occurrence of the saproxylic beetle Upis ceramboides. This is a species favored by open habitats and is said to respond positively to forest fires. The distribution area in Sweden for this species has decreased during the last two centuries and I wanted to see if there were differences between clear-cuts in Hälsingland, where it is very rare and decreasing, and Norrbotten where this study was conducted.

På våren 2014 invigs Litteraturhuset för barn och unga ? I Sandviken för hela regionen. Målgruppen ärbarn och unga, 0-18 år.

Under tre års tid har arbetet pågått som ett projekt, imaj 2013 beslutades att Litteraturhuset ska övergå i fast verksamhet.

Pneumonia is a common disease in calves. There are several causes behind the disease. The main purpose of this litterary study was to estimate what kind of nursing calves with pneumonia could benefit from, especially the evidence-based nursing recommendations for the sick calves. A further purpose was to gain knowledge of different treatments of sick calves and what kind of practical measurements that are most suitable to use in the preventive work. The results in this study shows that there are only suggestions of nursing, rather than some actual evidence-based actions. The most important nursing actions is to isolate the calves with dyspnea, prevent or treatment of hypothermia, potential dehydration and malnutrition. It is also important to make sure to place the calf on soft and dry bedding.
