Mikroskopie textiler Faserstoffe,denden Zellbündels nur selten die L?nge von 40 mm überschreitet. Man hüte sich deshalb, die nachstehenden auf die Einzelzellen bezüglichen Merkmale von Flachs, Hanf, Jute usw. an unmazerierten Fasern suchen zu wollen.

logists and sociobiologists are today taking over and as- suring us that they have the necessary tools to provide an answer to what perhaps seemed the most slippery subject in the hands of science: the social being. As might be expected, philosophers have reacted with some scepticism. Though human c

Paul Heermann mirror resting on the surface and stepped along it. Currently this non-contacting technique can achieve nanometre accuracy on flat or near-cylindrical surfaces, and it has the advantage of providing absolute values of profile height, related only to the direction of the beam from a laser as datum.

Paul Heermannsample. In each case, a qualitative comparison is made with the differential interference (Nomarski) micrograph of the same field of view..Since the measured phase gradients can be related directely to the laser wavelength, the technique can be made quantitative. By integrating the detected signal w

Paul Heermannends his philosophical efforts to the subject he considered most important of all, namely, natural theology. For, like Socrates, Brentano brought a kind of religious fervor to his philosophy precisely because he saw it as dealing much better than religion does with the matters that are closest to ou
