  1. 6. Rapid detection of drug resistance and genetic characterisation of Mycobacterium tuberculosis isolates in Honduras

    Författare :Senia Rosales; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: New challenges for tuberculosis (TB) control are emerging in the 21st century. The deadly combination TB/HIV as well as the development and spread of new forms of drug resistance are some examples. In this context, the timely detection of TB cases, especially of those with resistant TB is important. LÄS MER

  3. 7. Understanding the digital divide: Empirical studies of Thailand

    Författare :Chalita Srinuan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; accessibility; availability; affordability; Thailand; social inequality; market mechanism; digital divide; government intervention;

    Sammanfattning : The term digital divide was introduced in the 1990s to define the gap separating those who have access to new forms of information and communication technologies (ICTs) from those who do not. Later, scholars started looking more closely at the use of ICTs, instead of solely paying attention to access. LÄS MER

  4. 8. Tuberculosis and HIV : evaluation of new tests for diagnostic accuracy, cost-effectiveness and effect on treatment of tuberculosis in Smear-Negative HIV-positive patients in Uganda

    Författare :Simon Walusimbi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :accuracy;

    Sammanfattning : Background: Despite tremendous progress in the control of the global tuberculosis (TB) epidemic during the past decade, it is still a major health problem even today. The burden of TB is particularly severe in sub-Sahara Africa where TB and HIV co-infection is common, especially in those who are smear-negative. LÄS MER

  5. 9. Ocular accomodation. Studies of amplitude, insufficiency, and facility training in young school children

    Författare :Bertil Sterner; Göteborgs universitet; []
    Nyckelord :Accommodation; amplitude; children; dysfunction; facility; flip lens; insufficiency; ocular; sham treatment; subjective; training.;

    Sammanfattning : Aims: The purpose of this thesis was to establish the sufficiency of the ocular accommodation and to characterize accommodative problems and related symptoms among otherwise healthy young school children. The purpose was also to evaluate an accommodative facility training technique by studying the effect of the training on relative accommodation. LÄS MER

  7. 10. Ion Beam Analysis of First Wall Materials Exposed to Plasma in Fusion Devices

    Författare :Per Petersson; Göran Possnert; Anders Hallén; Marek Rubel; Eduardo C. Alves; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ion beam analysis; Microbeam; Plasma wall interaction; Deuterium; Beryllium; Carbon fibre composites; Divertor; Nuclear reaction analysis; Helium-3; Plasma physics with fusion; Plasmafysik med fusion; Ion Physics; Jonfysik;

    Sammanfattning : One major step needed for fusion to become a reliable energy source is the development of materials for the extreme conditions (high temperature, radioactivity and erosion) caused by hot plasmas. The main goal of the present study is to use and optimise ion beam methods (lateral resolution and sensitivity) to characterise the distribution of hydrogen isotopes that act as fuel. LÄS MER
