Gerhard Eisenbeis, a German entomologist, has written that outdoor lighting can have a "vacuum cleaner" effect on local insect populations, causing large numbers to be "sucked out of habitat".
Studying those changes alone gives a cleaner picture of the effect of tax reform.In the short to medium term, tax changes have large effects.
Visually, the photoelectric eye is so much more critical than the human eye that the effect of cleaner development does not matter there; it is in scanning the sound track that impurities arise and offend the ear in reproduction.
A subsequent effect of cleaners feeding at higher rates when they are hungry may be an increase in the probability of thresher sharks receiving a higher quality standard of service earlier in the day.
Again we contrast the pooled OLS results as the baseline with a fixed effects estimator, which provides cleaner estimates by removing the effect of personality traits.
A randomized controlled trial (RCT) was set up in the identified cleaners' workplaces to test the effect of cognitive behavioural therapy-based training (CBT) and physical coordination training (PCT) on cleaners' work ability, musculoskeletal symptoms and sick leave.
Cleaning can be carried out by use of a hopper with screens to remove large and medium-sized impurities, followed by magnetic separator to remove metal pieces and a cleaner-separator which combines the effect of sifting and pneumatic dust removal.
Thus, this paper considers for the first time life cycle environmental impacts of vacuum cleaners and the effects of the implementation of these regulations at the European level.
Including this latter variable in the model will allow us to obtain cleaner estimates of the impact of cognitive skills, since the effect of non cognitive skills will now be picked up, partially at least, by the locus of control.
In the face of their physical limitations, most participants made adaptations that mitigated the effect of the fracture; for example, employing a cleaner, moving to a nursing home or using a walking aid or other assistive device.
