Water and Ions in Biological Systems, Softcover reprint of the original 1st ed. 1985

As the First International Conference on Water and Ions in Biological Systems (Bucharest, June 25-27, 1980) was appreciated as a success, a second one was organized in the fall of the year 1982 under the sponsorship of the United Nations Educational, Scientific and Cultural Organization (UNESCO), the Romanian Academy of Medical Sciences, the Romanian Biophysical Society (Union of Societies for Medical Sciences in the Socialist Republic of Romania) and in co­ operation with the International Union for Pure and Applied Bio­ physics (IUPAB). The responsibility for the scientific program and organization of the Second Conference on Water fell on an International Scientific Committee which included Prof. J. Tigyi (Pees), President of the UNESCO Expert Committee on Biophysics, Prof. K. Wuthrich, Secretary General of IUPAB and Prof. H. Eisenberg, (member of the IUPAB Council) under the guidance of an Executive Board whose members were Prof. J. Jaz (representative of UNESCO), Prof. B. Pullman (Vice­ President of IUPAB) and Prof. V. Vasilescu (President of the Romanian Biophysical Society). The Meeting was attended by more than 250 specialists including 150 Romanian participants and others from Bulgaria, Czechoslovakia, England, the Federal Republic of Germany, the German Democratic Republic, Greece, Hungary, India, Israel, Italy, Japan, the Netherlands, Nigeria, Poland, Sweden, Switzerland, USSR, USA, Venezuela, Yugoslavia. The proceedings of the Conference took place in the Medical Faculty of Bucharest. The theoretical and practical importance of the Meeting was pointed out by the speakers, among whom were Prof.
