  1. 16. Personality, Health and Mortality of Workers in a PVC Production Plant in Sweden A longitudinal study

    Författare :Margareta Ardeberg; Miljö- och energisystem; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mortality; disease; recovery; personality alterations; solvents exposure; PVC; polyvinyl chloride; Sjöbring personality psychology; behavioural toxicology; MNT scale; MFS scale; Eysenck; Psychology; Psykologi;

    Sammanfattning : A longitudinal study was initiated in a PVC production plant in 1967. It was repeated in 1987. A cohort of 101 workers was followed. The aim of the 1967 study was, after a heavy rise in absenteeism and sick leave, to analyze perceptions of work environment and health. LÄS MER

  3. 17. Data analytics for weak spot detection in power distribution grids

    Författare :Hassan Mashad Nemati; Sławomir Nowaczyk; Anita Pinheiro Sant'Anna; Math Bollen; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This research aims to develop data-driven methods that extract information from the available data in distribution grids for detecting weak spots, including the components with degraded reliability and areas with power quality problems. The results enable power distribution companies to change from reactive maintenance to predictive maintenance by deriving benefits from available data. LÄS MER

  4. 18. Synthesis of substituted Ring-Fused 2-Pyridones and applications in chemical biology

    Författare :Christoffer Bengtsson; Fredrik Almqvist; Paul Helquist; Umeå universitet; []
    Nyckelord :Synthesis; 2-pyridone; 2-thiazoline; cross coupling; pili; curli; antibacterial; organisk kemi; Organic Chemistry;

    Sammanfattning : Antibiotics have been extensively used to treat bacterial infections since Alexander Fleming’s discovery of penicillin 1928. Disease causing microbes that have become resistant to antibiotic drug therapy are an increasing public health problem. LÄS MER

  5. 19. Telecommuting's implications on travel and travel patterns

    Författare :Jo Skåmedal; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Telecommuting; Computer science; Datavetenskap; Economic Information Systems; Ekonomiska informationssystem;

    Sammanfattning : The subject field is within technology and social change, with focus particularly on telecommuting and the possible changes that arises in the travel patterns as a result of the telecommuting situation. When a person starts working from home once or twice a week instead of commuting back and forth to the main work place, a number of changes in the telecommuters' distribution of travel can and most probably will arise.

  7. 20. The Synthesis and Use of Certain Pyridine Derivatives as Modulators of the G-protein Coupled Receptors mGlu5 and P2Y12

    Författare :Peter Bach; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mGluR5; P2Y12; gastroesophageal reflux disease GERD ; thrombosis; ethyl nicotinates; ureas; sulfonylureas; oxazoles; bioisosteres; regioselectivity; solvent effect.;

    Sammanfattning : The glutamatergic mGlu5 receptor and the purinergic P2Y12 receptor are two important targets in the development of novel treatments of gastroesophageal reflux disease (GERD) and thrombosis, respectively. Synthesis was developed to investigate the structure-activity relationships (SAR) of a novel series of 2-alkynylpyridine derivatives as mGluR5 antagonists. LÄS MER
