  2. 1. Single-­molecule spectroscopy of π-­conjugated polymers

    Author : Oleg Mirzov; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluorescence lifetime; low temperature; spectral diffusion; blinking; MEH-PPV; Single-molecule spectroscopy; π-conjugated polymers; 2D polarization; Monte Carlo; energy transfer;

    Abstract : When applied to condensed-matter samples of large organic molecules, optical spectroscopy faces the problem of inhomogeneous broadening caused by the diversity of environments and conformations that sample molecules are subjected to. This severely limits the information that can be extracted from optical spectra. READ MORE

  4. 2. Conformational and Dynamical Aspects of Conjugated Polymers and Oligomers of Interest for Photoluminescence

    Author : Mette Grage; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; femtosecond spectroscopy; conformations; anisotropy; excitation transfer; oligothiophene radical cations; MEH-PPV; Conjugated polymers; polythiophene; resonance Raman spectroscopy.; Chemistry; Kemi; Physics; Fysik;

    Abstract : Transient absorption laser spectroscopy and resonance Raman spectrscopy have been used to study conjugated polymers and oligomers. To extract more information the measurements have been compared to computer simulations and calculations. READ MORE

  5. 3. Liver cirrhosis : epidemiology, prognosis, and cancer

    Author : Bonnie Bengtsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Liver cirrhosis is a major risk factor for hepatocellular carcinoma (HCC). Patients with liver cirrhosis also have a high risk to develop infections leading to deterioration of liver function and increased mortality. READ MORE

  6. 4. Dizziness and fear of falling: A behavioural and physiological approach to Phobic Postural Vertigo

    Author : Johan Holmberg; Lund näs- och halssjukdomar Öron-; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; klinisk psykologi; psykosomatik; Psychiatry; audiologi; Otorinolaryngologi; audiology; Otorhinolaryngology; clinical; patients; exposure; behaviour; cognitive; psychological; psychotherapy; proprioceptive; postural control; Anxiety; Psykiatri; clinical psychology; hörsel- och talorganen; auditive system and speech; psychosomatics;

    Abstract : Dizziness is a common problem and it often co-exists with anxiety. Level of anxiety is the best predictor of handicap for dizzy patients. There is diagnostic controversy and few treatment programs for such patients. READ MORE

  7. 5. Carotid calcifications in panoramic radiographs in relation to carotid stenosis

    Author : Maria Garoff; Jan Ahlqvist; Eva Levring Jäghagen; Per Wester; Kostas Tsiklakis; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carotid stenosis; panoramic radiography; calcification; atherosclerosis; odontologi; Odontology;

    Abstract : Calcifications in carotid atheromas can be detected in a panoramic radiograph (PR) of the jaws. A carotid artery calcification (CAC) can indicate presence of significant (≥ 50%) carotid stenosis (SCS). READ MORE
