Researchers in lots of disciplines were enthusiastic about modeling textual information which will account for texts because the basic details unit of written verbal exchange. The booklet “Modelling, studying and Processing of Text-Technological information constructions” bargains with this difficult info unit. It makes a speciality of theoretical foundations of representing typical language texts in addition to on concrete operations of computerized textual content processing.
In regards to the ProductPublished through the yankee Geophysical Union as a part of the distinctive courses sequence. presently after the invention of kimberlites, the eye of investigators was once interested in their strange mineralogy. it's been tested that, in addition to the fragments stuck up from quite a few crustal rocks, xenoliths of bizarre kinds take place within the kimberlites, believed by way of so much investigators to were mentioned from nice depths.
Vital Transforms of Geophysical Fields function one of many significant instruments for processing and reading geophysical info. during this booklet the authors current a unified therapy of this thought, starting from the thoughts of the transfor- mation of 2-D and 3-D capability fields to the speculation of se- paration and migration of electromagnetic and seismic fields.
Sleek researchers in plate tectonics will be occupied with the research of allotted deformation throughout diffuse plate limitations and triple junction zones. This publication extends vintage equipment of kinematic research first built within the Sixties to the extra basic eventualities of diffuse deformation zones among plates.

This seems to be the only direct determination of the ozone flux density made up to the present time. 0 x lolo. All these estimates are smaller than Regener’s value. They were expected to be equal or larger and cannot be considered very reliable. Another set of ground air data was obtained by Teichert (1955). He recorded the ozone concentration on an 80-meter high radio tower and a t ground level over a period of several months. His hourly means for different months are given in Table 9. The values a t 80 meters are always higher than or equal to those at ground level.
The resulting flux of CO, in the atmosphere from low to high latitudes must be counterbalanced by a corresponding flux in the ocean when arctic waters sink and spread to low latitudes. 3 25 CARBON DIOXIDE Ranwisher (1960) points out that a t least locally, the growth and decay of marine plankton can result in considerable changes of the [CO,] of ocean water with a seasonal trend, but there are too few data to reveal any seasonal effects over sea water and to estimate the biological influence. Naturally, daily variations are small over the oceans.
The carbon cycle is an outstanding example of the succesi ful application of isotopic methods to geophysical problems. There wer earlier estimates of the exchange times between the reservoirs, but reliabl values were obtained only after C14 measurements became available. Ou present knowledge is based on a series of papers by Craig (1957), Revel1 and Suess (1957), and Arnold and Anderson (1957). These studies we1 concerned mainly with the exchange time t,, of the CO, between the a1 mosphere and the ocean.
