Principe en toepassing van de raster-elektronen-microscoop worden beschreven. Door de grote dieptescherpte, de ruimtelijke afbeelding en de mogelijkheid om vrij grote objecten te onderzoeken is deze mciroscopische techniek bijzonder geschikt voor het onderzoek van technische materialen. Doch ook bij het onderzoeken van biologische structuren,...

Unfavorable work characteristics, such as low job control and too high or too low job demands, have been suggested to increase the likelihood of physical inactivity during leisure time, but this has not been verified in large-scale studies. The authors combined individual-level data from 14 European cohort studies (baseline years from 1985-1988...

The sensitivity of different parameters for the determination of lung injury caused by nitrogen dioxide (NO2) was investigated. Male rats were exposed to concentrations of 0, 4, 10 or 25 ppm NO2 for 6 h/day, for 7, 14 or 21 days. Histopathology of the nasal cavity, larynx, trachea and lungs was compared with the changes in macrophage function...

The ecotoxicity of lactic acid, its alkyl esters and selected metal salts was studied experimentally with the micro alga Selenastrum capricornutum, the crustacean Daphnia magna and the fish species Brachydanio rerio and Pimephales promelas. In addition, the biodegradation of lactate esters was also studied. The aim of the study was to provide...

The aim of the study was to determine whether men and woman with equal tasks perform these tasks in the same way. Video recordings of 37 male and 43 female workers in six task groups were observed, from which data regarding frequency and duration of exposure to awkward postures were derived. These data were also compared to self-reported...

Introduction: Workers with chronic low back pain (LBP) mean a heavy human and social-economic burden. Their medical histories often include different treatments without attention to work-relatedness or communication with occupational health providers, leaving them passive and medicalized in (outpatient) health care. So we developed and...

The effects of exposure pattern on the toxicity of acetaldehyde vapour were investigated in 4-week inhalation studies. Male rats were exposed to 500 or 150 and 110 ppm for 6 h per day/5 days per week. One group of animals was exposed without interruption, the exposure of a second group was interrupted for 1.5 h between the first and second 3-h...

Maar beïnvloedt de bedrijfscultuur, sociale sfeer en het bieden van perspectieven niet ook de kans de kans dat iemand wel of niet langdurig uitgeschakeld wordt? Een analyse van de rol van kwaliteit van arbeid in brede zin....
