  4. 3. Application of Passive DOAS using Scattered Sunlight for quantification of gas emissions from anthropogenic and volcanic sources

    Författare :Claudia Rivera; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nitrogen dioxide; DOAS; gas emission; sulphur dioxide; volcanic; formaldehyde.; scattered sunlight; anthropogenic;

    Sammanfattning : Monitoring of gas emissions from natural and anthropogenic sources is important due to the negative effects of these emissions on human health, atmospheric quality and ecosystems. Concern over air pollution has increased the need to develop measurement techniques suitable for gas flux determination. LÄS MER

  7. 5. Digital Mammography with a Photon Counting Detector in a Scanned Multislit Geometry

    Författare :Magnus Åslund; Mats Danielsson; Ehsan Samei; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mammography; digital; photon counting; scanning; detective quantum effciency; scattered radiation; automatic exposure control; Physics; Fysik;

    Sammanfattning : Mammography screening aims to reduce the number of breast cancer deaths by early detection of the disease, which is one of the leading causes of deaths for middle aged women in the western world. The risk from the x-ray radiation in mammography is relatively low but still a factor in the benefit-risk ratio of screening. LÄS MER
