Biology, life sciences

Two years ago, about twenty people gathered informally in our institute to discuss mitosis.

The use of the term "e;advanced"e; in the title of this book is somewhat ar- bitrary and very much relative with respect to time.

Dynamic Morphology is the attempt to correlate surface architec- ture and shape of fixed cells, as visualized by scanning electron microscopy (SEM), with the behavior of living cells, recorded by microcinematography (MCM).

A knowledge, which is as accurate as possible of microbial ecology is indispensible for ecosystem research and environmental protection.

The establishment of the morphologically and physiologically intimate contact be- tween two genetically different individuals, mother and embryo, which takes place during implantation, has always exerted a fascination on researchers in biology and medicine.

The change in greenhouse operation and technology in the last 20 years has been unprecedented.

One aim of the physical sciences has been to give an exact picture of the material world.

Cytological techniques have greatly improved in the last twenty years, largely as a result of further development of the microscope.

It is a privilege and pleasure to write a foreword to this work.

Despite the amazing progress made by the stereotactic technique, particularly regarding the localization of the target, despite the extreme caution, which stereotactic neurosurgeons apply at every step of the procedures, despite the routine roentgenologic and physiologic controls (depth EEG, electric stimulation) preceding the production of a lesion, there remains a certain degree of uncertainty regarding the position, shape and extent of the lesion as well as of the electrode track and also regarding unintended lesions in the vicinity.
