   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automatic assessments; data visualization; data-driven modelling; home assessments; information technology; mobile computing; objective measures; Parkinson’s disease; quantitative assessments; remote monitoring; spirography; symptom severity; tapping tests; telemedicine; telemetry; time series analysis; web technology; Information technology; Informationsteknologi; Datavetenskap; Computer Science; PAULINA - Uppföljning av Parkinsonsymptom från hemmet;

   Sammanfattning : A challenge for the clinical management of Parkinson's disease (PD) is the large within- and between-patient variability in symptom profiles as well as the emergence of motor complications which represent a significant source of disability in patients. This thesis deals with the development and evaluation of methods and systems for supporting the management of PD by using repeated measures, consisting of subjective assessments of symptoms and objective assessments of motor function through fine motor tests (spirography and tapping), collected by means of a telemetry touch screen device.

3. 27. Hyperspectral Image Generation, Processing and Analysis

   Författare :Hamed Hamid Muhammed; Ewert Bengtsson; Tommy Lindell; Erkki Oja; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; hyperspectral imaging; colour filter mosaics; remote sensing; crop reflectance; surface water quality; disease severity; plant density; linear system of equations; waste water detection; chlorophyll a; suspended paticulate matter; weighted fixed neural networks; weighted incremental neural networks; camera spectrometer; Bildanalys; Image analysis; Bildanalys;

   Sammanfattning : Hyperspectral reflectance data are utilised in many applications, where measured data are processed and converted into physical, chemical and/or biological properties of the target objects and/or processes being studied. It has been proven that crop reflectance data can be used to detect, characterise and quantify disease severity and plant density. LÄS MER

4. 28. Extraction of polymeric rapeseed straw hemicelluloses for renewable films

   Författare :Antonia Svärd; Ulrica Edlund; Elisabet Sjöholm; Emma Strömberg; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; rapeseed straw canola straw; hemicellulose; xylan; mannan; extraction; characterization; severity factor; hemicellulose film; Kemi; Chemistry;

   Sammanfattning : Polymeric hemicelluloses with high molecular weight were extracted from rapeseed straw with a straight forward hydrothermal extraction method, evaluated and refined by statistical factorial screening design and ‘severity factor’ analysis. The influence of the extraction conditions, time, temperature and pH of the extraction liquid, on the composition, molecular weight, yield and properties was unveiled. LÄS MER

5. 29. Psychometric studies of the Swedish version of the Adolescent Drug Abuse Diagnosis (ADAD) instrument

   Författare :Josefine Börjesson; Helene Ybrandt; Bengt-Åke Armelius; Anders Tengström; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ADAD; validity; reliability; assessment; psychometric; severity index; composite score; normal; antisocial adolescents; psychological health;

   Sammanfattning : This thesis describes studies into the psychometric properties of a Swedish language version of the Adolescent Drug Abuse Diagnosis (ADAD) instrument. The psychometric properties of this instrument have been examined in two previous studies: an American study was conducted by the developers of the interview, Friedman and Utada (1989), and a Swiss study was undertaken by Bolognini et al.

7. 30. Cardiopulmonary involvement in Puumala hantavirus infection

   Författare :Johan Rasmuson; Clas Ahlm; Anders Blomberg; Jamshid Pourazar; Gregory J. Mertz; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hemorrhagic fever with renal syndrome; hantavirus; echocardiography; respiratory function tests; computed tomography; bronchoalveolar lavage; biopsy; cytotoxic T cells; disease severity; Infectious Diseases; infektionssjukdomar;

   Sammanfattning : Puumala hantavirus (PUUV) causes hemorrhagic fever with renal syndrome in Europe. After inhalation of virus shed by bank voles, the virus systemically targets the vascular endothelium leading to vascular dysfunction and leakage. LÄS MER
