  1. 1. Cyanide in breath as a marker for cyanide poisoning

    Författare :Kristin Stamyr; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Approximately 120 people die every year due to fires in Sweden. A majority of the fire victims die due to toxic fire gases. Carbon monoxide is often thought to be the major cause of death. Still, another very toxic fire gas, hydrogen cyanide, is formed when materials containing nitrogen burn, e. LÄS MER

  3. 2. Quantum Chemical Exploration of Nitriles in Prebiotic Chemistry and Astrobiology

    Författare :Hilda Sandström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metadynamics; astrochemistry; iminoacetonitrile; hydrogen cyanide; acrylonitrile; azotosome; Titan;

    Sammanfattning : The Universe hosts countless different chemical environments, such as planets, moons, comets and the interstellar medium. The diverse pressures, temperatures and chemical compositions of these environments make a wide variety of processes possible. LÄS MER

  4. 3. Nitriles in Prebiotic Chemistry and Astrobiology

    Författare :Hilda Sandström; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; astrobiology; polymer chemistry; hydrogen cyanide; density functional theory; molecular dynamics; metadynamics; umbrella sampling; prebiotic chemistry;

    Sammanfattning : Life appeared on Earth within a billion years of the planet’s formation. How? - no one knows. Theories regarding the origin of life involve reactions of molecules predicted to have existed on early Earth in what is called prebiotic chemistry. LÄS MER

  5. 4. Upconversion Detection for Improved Nonlinear Mid-infrared Spectroscopy in Flames

    Författare :Rasmus Lyngbye Pedersen; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; infrared; upconversion; degenerate four wave mixing; hydrogen cyanide; polarisation spectroscopy;

    Sammanfattning : This thesis deals with the addition of upconversion detection to non-linear mid-infrared laser spectroscopy techniques. The techniques investigated here are degenerate four wave mixing (DFWM) and infrared polarization spectroscopy (IRPS). LÄS MER

  7. 5. Feeding cassava foliage to sheep : nutrient properties and hydrogen cyanide toxicity

    Författare :Khuc Thi Hue; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The potential of cassava foliage (Manihot esculenta Crantz) as a protein-rich feed in sheep production in Vietnam was examined by studying cassava foliage yield, hydrogen cyanide (HCN) content, toxicity and performance of lambs fed the foliage as a supplement. Cassava foliage fed ad libitum as a protein supplement to a basal diet of urea-treated rice straw gave similar lamb live weight gain (LWG) as diets supplemented with commercial concentrate or protein-rich foliage of stylosanthes (Stylosanthes guianensis) or jackfruit (Artocarpus heterophyllus).
