Trials in the treatment of the leukemias are sometimes based on a hypothesis, as in the case of exchange transfusion [33] or the use of antimetabolites [86].
Reflectance spectroscopy is the investigation of the spectral composi- tion of surface-reflected radiation with respect to its angularly dependent intensity and the composition of the incident primary radiation.
(Abridged and translated) Organic photochemistry may be divided into three parts: theory which is the province of the physical chemist; instrumentation which requires the skill of both physicist and engineer; and preparation which falls within the sphere of the organic chemist.
Mit der vorliegenden Monographie wird der Versuch unternommen, den gegenwärtigen Wissensstand auf dem Gebiete der chemischen Techno logie des Polyvinylchlorids und der Vinylchlorid-Mischpolymerisate zu sammenfassend darzustellen.
For many years, the subject matter encompassed by the title of this book was largely limited to those who were interested in the two most economically important organic materials found buried in the Earth, namely, coal and petroleum.
If we possessed a true, well established and undoubted theory concerning the function of the nerves in the human body, the principles of smell would be much easier to understand.
In recent years considerable interest has developed in the mathe- matical analysis of chemically reacting systems both in the absence and in the presence of diffusion.
Although it was shown very early [1] that the isotope 29Si is very valuable for NMR research, severe technical difficulties had to be overcome before silicon spectra could be recorded.
The Second International Conference on Ion Formation from Organic Solids (IFOS II) was held at the University of MUnster, Federal Republic of Germa- ny, from September 7 to 9, 1982.
In recent decades surface science has experienced a large growth in connection with the development of various experimental techniques which are able to characterize solid surfaces through the observation of the scattering of ions, electrons, photons or atoms.
The subject of geomagnetic micropulsations has developed extremely rapidly and it is difficult to know when is an appropriate time to pause and assess the sum total of our knowledge-both observational and theoretical.
