A method is described which allows to visualize progressive surface waves without impairment dur to noise caused by imperfections and dirt particles on optical elements. An improvement of the signal to noise ratio by a factor of 160 is achieved....

Image analysers have been built to measure these parameters rapidly. Stereological equations are used to define three-dimensional characteristics from elementary count operations made in a plane.These techniques were used to characterize the air bubble system of six different concretes. All measurements ...
The fragmentation of 3,6-dibenzyl, 2,5-diketo piperazine in the mass spectrometry is presented. The general mechanism is proposed and discussed.Krzysztof JankowskiLouis Varfalvycanadian journal of chemistry
The advantages presented by this new method justify the investigation into the problems posed by the choice of a tracer and by the circulation. These advantages include the localised nature of the investigation, limited radiation in terms of both space and time, and the possibility of two-...
