Zrimec et. al). Overview of experimental results of nonthermalbiological effect of microwaves based on presentstate of the art shows a necessity of minimizing theiradverse effects (I. Belyaev).Effects of bioelectrochemical methods for cancertherapy causing electrolytic cell destruction, electroporationof membranes, and changes of metabolism can be enhancedby hyperthermia, by photodynamic action, and by cytotoxicagents (H. Berg). Medical application of microwaves musthave adequate technical basis (J. Vrba). First experimentalresults on microwave imaging (microwave tomography)shows possible application in medicine (M. Persson et al.).Microwave pulses from MRI scanners induce acousticpressure waves in head (J.C. Lin and Z. Wang). Experimentalvisualization of light piping channels in humans waspresented (F.-A. Popp et al.). Measurement of yeast cells at42 GHz and power level 10 -17 W does not reveal statisticallysignificant exited vibration modes (F. Jelínek et al.).Two “Round table discussions” were included intothe program of the Symposium: “What effects haveelectromagnetic fields on water?” and “Role of physicalforces in organization of living matter”.What effects have electromagnetic fields on water:The main physical contributions were made by theV.I. Lobyshev and E. Del Giudice. The symmetry,multiplicity and cooperativity of hydrogen bonds determinethe collective properties of water distinguishing it fromsimpler fluids. Changes of physico-chemical properties ofwater and aqueous solutions under the action of weak fieldsof electromagnetic, as well as of the acoustical, andvibrational nature are registered. For understanding ofwater properties optical characteristics in UV, visible, andIR ranges, electric and thermodynamic characteristics areimportant. Luminescence in UV and in visible range showsthat the structural equilibrium in water is not stable ingeneral. Physical measurements suggest the existence ofvarious supramolecular hierarchic structures in liquid water(the positive and the negative charges—„binding sites“—of a water molecule form corners of a nearly regulartetrahedron). Water at each moment of time constitutes astructure containing ordered clusters and disordered regionslike a crystal with defects. The principal step is made fromwell-known crystalline structures to parametric structuresof generalized crystallography. At room temperature andpressure liquid water is a mixture of coherent and noncoherent fractions. Measurements of the effects of watertreated by the electromagnetic field on properties ofbiological systems—on bacteria Escherichia coli and oncress seeds—were presented too (R. Krašovec et al, R.Ružiè et. al.).Role of physical forces in organization of living matter:Contributions of E. Del Giudice, of G.J. Hyland, ofF.-A. Popp, of V.N. Binhi, of L.S. Brizhik of A.R. Liboff,of M.V. Satariæ, and of J. Zon pointed out the fundamentalphysical concepts in organization. Organization has to beunderstood as organization of morphological structures, ofspacio-temporal chains of chemical reactions, and ofgeneration of endogenous electromagnetic fields. Largenumber of particles coupled to the electromagnetic field canform coherent domains. Macroscopic wave functions candescribe the biologically relevant states. Non linear solitondymanics can participate in transfer of charges and energy.Water bound in biomolecules have significant role inmolecular dynamics. Electromagnetic field can participatein transport of charges and dielectric particles (molecules)and form lines of force structures for positioning of material.All processes in biological systems have a deterministic (orcoherent) and a random (thermal) component. Generally,organization of biological systems cannot be understoodwithout taking into account endogenous electromagneticfields.The symposium was devoted to the vigorouslydeveloping area of human knowledge about living matter.About one hundred scientists from 20 countries participatedin the Symposium, presented papers and took part indiscussions about fundamental physical concepts of life.The Symposium took place in Prague, the Czech Republic,from July 1 to July 4, 2005 and was organized by theInstitute of Radio Engineering and Electronics of theAcademy of Sciences of the Czech Republic, by the IstMedical Faculty of the Charles University, by the Facultyof Electrical Engineering of the Czech Technical Universityin Prague, by the National Institute of Public Health of theMinistry of Health Care of the Czech Republic, under theaegis of Professor Š. Svaèina, dean of the Ist Medicalfaculty and of Dr. V. Matìjec, director of the Institute ofRadio Engineering and Electronics, under auspices of theInternational Comission K of URSI, and of the NationalURSI Committee of the Czech Republic, and of theCzechoslovak Section of IEEE. Honorary organizers wereUniversità degli Studi di Milano, Bicocca—Italy, Universitàdegli studi di Salerno—Italy, Department of Biophysics ofthe Faculty of Mathematics, Physics and Informatics of theComenius University in Bratislava—Slovak Republic, andthe Catholic University in Lublin—Poland.Invited papers will be published in the journal“Electromagnetic Biology and Medicine”—24(3)2005.J.
