abstract: Ultrasonic pulse echo technique is a valuable and non destructive tool to explore elastic properties of materials. We propose a new instrument based on mass produced microchips. In our design, the signal is processed by an AD8302 RF gain and phase detector (www.analog.com) Its phase output is linearly proportional to the phase difference between the exciting and response signals. The gain output is proportional to the log of the ratio of amplitudes of the received to the exciting signals. To exclude the non linear fragments and to enable exploring large phase changes, we employ a parallel connection of two detectors, fed by in phase and quadrature reference signals, respectively. The interferometer was tested by measuring the temperature dependences of both sound speed and attenuation in metallic glasses as well as in ferroelectric KTaNbO3 (KTN) single crystals. The instrument allows for exploring phase transitions with precision of DV/V 10 7 (V is ultrasound speed) in the broad dynamic range from 60 to x 20 dBm. These qualities allowed us to detect the theoretically predicted, but not observed previously velocity kink at the KTN phase transition from tetragonal to orthorhombic symmetry, whereas the attenuation curve showed new features in the development of the low temperature structure of the KTN crystal.

abstract: The Department of Physics at UL Lafayette has a strong history of acoustics research. Recently, the program has expanded considerably as a result of renewed interest in acoustics related research. Tied into the current rethinking of the Department's multiple physics tracks, the Physical Acoustics Research Program offers ample opportunities for students both undergraduate and graduate to be involved in wide spectrum research in acoustics. This program, unique in Louisiana, involves acoustic sensing of alien environments, atmospheric and underwater acoustics, ultrasonics in the solid state, ultrasonic materials characterization and structural health monitoring, seismology and geodynamics. In parallel to research projects, the faculty offer a variety of acoustics related courses on topics such as Matlab and Python based computational acoustics, solid state acoustics, experimental techniques in acoustics, room acoustics, as well as machine learning techniques for wave propagation.

abstract: This is the fifth volume in this series dealing with general problems of chemical structure and bonding forces. It consists of five articles. Two articles have biochemical implications 'Biochemical aspects of iron sulfur linkage in non heme iron protein' by T. Kimura, pp. 40; 'Reaction of some transition metals with nucleic acids and their constituents' by U. Weser, pp. 27) and one article is purely theoretical 'A perturbation representation of weak covalent bonding' by C.E. Sch~iffer, pp. 28) There is an article (in German) on homogeneous catalysis by W.Strohmeier (pp. 22) and an article on 'The thermodynamics of complex formation between hard and soft acceptors and donors' by S.Ahrland (pp.31) As in previous volumes in this series the spread of interest is wide, and I cannot imagine any one reader being interested equally in all the articles. It would perhaps be unwise for a reviewer to attempt a critical evaluation of the articles and the prudent course of action would seem to be to attempt brief summaries and leave the reader to judge the articles that seem to interest him. The article by Kimura is primarily a review of the recent work done in his own laboratory on the non haem iron protein serving as an electron transfer intermediate in steroid hydroxylation in mammalian glands. To some extent it supplements the article of Buchanan which appeared in Vol. 1 of this series. The article by Weser is a systematic review of what is known about the interactions of transition metals with monomer and polymer units of nucleic acids. Some attempt is made in the article to suggest, tentatively, correlations between metal polynucleotide interactions and biochemical pathways. Sch~iffer presents a formalization and elucidation of a ligand field model for highly heteropolar situations, by means of the representations of the full rotation group carried by the real atomic orbitals. In this way he is able to exhibit clearly the parametrization of the model. Strohmeier's article on homogeneous catalysis is an attempt to develop a simple model for such catalysis in terms of a suggested mechanism and the structure of the activated complex. The final article, by Ahrland, collects a great deal of thermodynamic data on complex formation and proposes an elucidation of it in terms of the ideas of hard and soft acceptors and donors, given a theory of the nature of the coordinate bond.

abstract: The experimental results in the field of laser generation of acoustic pulses of duration less than 1 ns are reviewed. The various physical mechanisms of optoacoustic conversion are analyzed theoretically. Possibilities are shown for shortening the duration of optoacoustic pulses by increasing the intensity of the laser exposure. The prospects of initiating ultrashort, strong shock pulses with high power femtosecond light pulses, are discussed.

abstract: 49th Winter School on Wave and Quantum Acoustics constituted platforms for sharing the results and achievements obtained in different branches of physical acoustics, as molecular acoustics, quantum acoustics, acousto optics, magnetoacoustics, photoacoustics, acoustics of solid state, acoustic emission, and others. Moreover, researches in some selected topics related to those mentioned above (e.g. optoelectronics, relaxation processes) were presented during the school. The conference consisted of the 16th Workshop on Acoustoelectronics and the 16th Workshop on Molecular Acoustics, Relaxation and Calorimetric Methods. However, the organizers are opened to organizing workshops on other subjects in future. We would like to invite scientific centers and other professional groups to cooperate in organizing workshops on the subjects of their interests. XLVIIIth Winter School on Environmental Acoustics and Vibroacoustics was a forum for all environmental and vibroacoustics fields. Particularly it was concerned with traffic noise, vibroacoustics of machines, room acoustics, building acoustics, noise protection and similar problems. During the Conference, seminars on "Measurement of noise and vibration at the workplace" and Environmental noise monitoring" combined with measurement workshops, were organised in association with SVANTEK. The Conferences began with the special, joined session dedicated to celebration of the 15th Jubilee Conference Integrated Optics Sensors, Sensing Structures and Methods. In summary, 48 people participated in Conferences and seminars, presenting 37 lectures, reports and posters. In this issue one can find abstracts of some lectures and posters, which were presented during the Conferences.
