Even minor health effects may be important for the whole population. Stroke patients require the largest number of days spent in hospitals and nursing homes than any other medical condition group. Risk factors for stroke include smoking, high alcohol intake, physical inactivity, hypertension, hypercholesterolemia, high waist-hip ratio and diabetes.

Sweden has a long tradition as a mapmaking nation. Tens of thousands of historical maps,dating from the sixteenth century and onwards are still preserved in archives today, providinga rich resource for studies of city growth and changes in the landscape through time. For morethan ten years an effort has been made by public authorities to transfer this material frompaper onto digital media. Due to modern technology, as for example GeographicalInformation Systems (GIS), researchers have been given improved possibilities to study andanalyze this material. This study uses a qualitative approach, based on both literature studiesas well as map studies.

This bachelor thesis discusses various difficulties with architectural paint research. The difficulties are exemplified through a case study ? a paint research on a furrowed string-course in the southern vault of the Royal Palace of Stockholm, which was carried out November ? March 2009-2010 on behalf of Statens Fastighetsverk. The paint research was made in order to receive information about the string-course and to get inspiration for a renewed color scheme on it. The base material of the string-course is Gotlandic sandstone and the surface of it is furrowed.

Unit testing is a type of testing technique which is becoming quite fashionable to the developers and companies that are in the business of creating and managing software. Alas there are seldom any concrete data to support the positive claims of the authors in unit testing methodology books. These claims are instead based on empirical studies and the experience of the authors. The problem that arises from this situation is that it becomes problematic for managers and also the developers themselves to convince both customers and their own management to use this type of testing as there is no exact return of investment model. This essay examines this problem from two points, the first point is from the literature itself and interviews conducted with a number of developers at a software company located in Umea, Sweden.

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.

The aim of this Bachelor's thesis is to examine library directors'views on weeding in Swedish public libraries. The researchquestions posed are: What formal goals and criteria govern theweeding process?; How are these goals and criteria accountedfor?; How do the library directors view the weeding in relationto the roles of the collections?The theoretical framework consists of a division of weedingcriteria inspired by Stanley J. Slote, and a slight adaptation ofMichael K. Buckland's roles of collections.

Background: Flavan-3-ols are polyphenolic phytochemicals belonging to the flavonoids. Flavan-3-ols are present in many higher plants and are particularly concentrated in e.g. Camellia sinensis (tea) and Theobroma cacao (cacao) and have got attention due to their antioxidative capacity. Many studies have been able to associate flavan-3-ol-rich foods to improved endothelial function. The aim of the present work is to review the scientific literature and evaluate the evidence for positive effects of flavan-3-ols on endothelial dysfunction in humans. Method: Scientific articles describing intervention and observational studies about flavan-3-ols and endothelial dysfunction, were searched for on http://www.pubmed.org.

To be able to hinder the global warming the emissions of greenhouse gases, carbon dioxide foremost, must decrease. By switching to green electricity, it is possible to reduce the emissions from electricity producing sources.In 1999, Swedenergy conducted a study about whether or not Swedish households would consider buying green electricity. According to the study, about 75 percent were willing to buy green electricity. 40 percent of these were prepared to pay a premium for green electricity. However, according to the results from the study, only one percent actually bought green electricity, and since 1999, this proportion has merely increased slightly.

This essay is a survey of thirteen user studies performed in the field of image retrieval. The purpose is to try to distinguish principles that should be kept in mind when wanting to make image databases available for a wide and varied group of users. The essay tries to answer two questions, namely: Are there any results in accordance among the different studies? What in the user studies should be considered when it comes to how content description, interface and functions for searching can be designed when creating systems for image retrieval? Each study is first reviewed on its own, and then a comparative analysis of all the studies is carried out. Derived from the result of this analysis, the conclusion is presented in the form of a row of suggestions to which aspects are to be suitably included in the design of image databases.

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.

With the technological development of the last decades, an increasing number of genealogists are carrying out their research online. The purpose of this master?s thesis is to examine how and why genealogists' information behavior has been influenced by the use of online services for genealogy. Using a conceptual model of genealogists' information behavior as theoretical basis for the study, I examine how the use of online services affect genealogists? search process, what information they are looking for and what information resources they use.

From a postcolonial and feminist perspective this paper examines how gender, ethnicity and the Other is being created in documentary films about the conflict between Israel and Palestine. When and in what way are gendered metaphors and subtexts used? Are stereotypes of gender and ethnicity being empowered or enforced? When and in what way are boundaries created between Israel and Palestine and against Sweden? The aim of this study is to point at how postcolonial imaginations affect stories about the Other..

The organized and controlled form of collecting consumption taxes and toll from the import and export trade goes back to the 17th century in Sweden. The customs administration and procedure were regulated by royal announcements, and the majority of the documents found in the customs archives represent thus records stipulated by such notifications. The customs archives can be used for research on several levels; the announcements reflect currents within both the domestic and foreign politics, while the account lists for financial statistics portray the extent of the trade. The various lists of compilation can be further used to follow for instance the development of different units of measurement, the expansion of tax rates, the value of trade goods or the changes in monetary units or systems. The diaries, architectural plans of the customs offices and maps of the toll areas place the customs officials and their work within the local scenery.The thesis focuses on archives deriving from customs located at harbors and on the Swedish-Norwegian border in the county of Dalarna.

This study discusses the relationship between studies and part-time work. The aim is to gain a deeper understanding of why students enrolled in the programme of human resource management and working life choose to undertake part time work, specifically in the human resource business in such great extent while studying full time and what this means for the students regard gaining knowledge. It focuses on the students experience and in order to gain the understanding of this phenomenon three qestion formulations were formed; ?What are the reasons formed by the interviewed human resource-students for having part-time work in the human resource bransch, in addition to their full-time studies??, "What values are made visible regarding the students choices of having a part-time work in addition to their full-time studies?" and ?How does the students express the thought about their part-time work as a key to learn from their studies?? The empirical data were collected through interviews with eight branch-specific human resource-students. The data was analysed based on previous research and a theoretical framework consisting of Lave & Wenger's theory of communities of practice and John Deweys theory of learning by doing.

For my advanced degree in archival science, I have organised and catalogued two family archives; man Family Archives ("Gardtmanska släktarkivet") and the Hamnström Family Archives ("Hamnströmska säk- tarkivet"). Though both could be labelled "family archives", there were many differences between the two. The Gardtman Family Archives contained the records of several family members from a period of several centuries, spanning from the early 17th century, to the early 20th century. It was by far the larger of the two archives. A substantial part of the records consisted of documents regarding various agricultural estates the family had owned or been involved with in one way or another.
