    Sammanfattning : Eta Carinae is one of the most massive and luminous stars in the Galaxy. A huge bipolar nebula and an equatorial disk give the object a characteristic shape. Close to the star there are gas clouds, which emit intriguing emission line spectra. LÄS MER

  4. 3. Improving the prevention of sexually transmitted infections (STIs) : a study using Chlamydia trachomatis as a model infection

    Författare :Daniel Novak; Roger Karlsson; Berit Andersen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Public health; STI; Prevention; Chlamydia; Postal screening; cost effective; condom; Internet; self-selective screening; Folkhälsomedicin; Public health medicine research areas; Folkhälsomedicinska forskningsområden; Family Medicine; allmänmedicin;

    Sammanfattning : Despite the current preventive strategies sexually transmitted infections (STIs) are rising. This thesis presents a model with the aim of improving the prevention of STIs. Chlamydia being the most common STI in Sweden serves as a model infection. The presented model is based on five performed studies. LÄS MER

  5. 4. Public health economics of chlamydia and other STIs : aspects of risk, prevention and resources

    Författare :Charlotte Deogan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The overall aim of this thesis was to increase the knowledge of the public health economic aspects of chlamydia and other STIs, in terms of risk, prevention and resources. In Study I, we examined the association between demographic, socioeconomic and lifestyle factors and the risk of self-reported chlamydial infection among young adults in the Stockholm public health cohort.

  7. 5. Poverty of opportunity for women selling sex in Lahore, Pakistan : knowledge, experiences and magnitude of HIV and STIs

    Författare :Mohsin Saeed Khan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Human Immunodeficiency Virus;

    Sammanfattning : Background: According to the UNAIDS’ estimates, the incidence of HIV infection has decreased by 19% over the last ten years. WHO estimated in 2005 that approximately 448 million cases of four major curable STIs occur in adults in the age group 15-49 years. LÄS MER
