Travel using time productively

In addition, we conclude that most passengers already find their travel time valuable and do not only perceive it as wasted time or a cost. We find some indications that ICT may play a reinforcing role here, a crucial issue for further data analysis. We also find that using time productively (for study or work) and using various types... 

The intensity of signal transmitted to the detector is greatly improved by using time-of-flight methods instead of mechanical velocity selectors. The beam of product molecules is chopped into a sequence of short pulses and the molecules then travel a known distance before being detected. The time-of-arrival spectrum at the detector gives the velocity distribution of the products [30]. This method of velocity analysis is now widely used in studies of crossed-beam reactions [111]. 

The primary disadvantage is that if these bailers are adjusted to remove only the LNAPL layer, they do not create a drawdown cone. Therefore, unless the product layer is relatively thick and quite fluid, the recovery rate tends to be slow. Also, use of bailers in deeper wells requires significant bailer travel time, which can decrease the effectiveness.
