A solvable model of lateral line of a fish based on a wave equation with additional boundary conditions on a set of isolated points is *** the framework of this model it is shown that the ratio of pressures on lateral lines on different fish flanks,as well as the cross section of sound scattering on both the lines,strongly depends on angles of incidence of incoming sound *** strong angular dependence of the pressure ratio seems to be sufficient for the fish to determine the directions from which the sound is coming.

In this work, the hydrogen storage properties of the mg-based hydrides, i.e., mgl-xmxH2 （m=Ti, v, Fe, 0≤ x ≤ 0.1）, are studied using the Korringa-Kohn-Rostoker （KKR） calculation with the coherent potential approximation （CPA） . In particular, the nature and concentrations of the alloying elements and their effects are studied. moreover, the material＇s stability and hydrogen storage thermodynamic properties are discussed. In particular, we find that the stability and the temperature of desorption decrease without significantly affecting the storage capacities.

Combat vehicles using armour grade quenched and tempered （Q＆T） steel are needed to be operated under different climatic conditions. However, the properties meeting the room temperature test conditions may not neces-sarily be required to meet the low temperature operating conditions. The influences of shielded metal arc welding （SmAW） process, flux cored arc welding （FCAW） processes and test temperatures below room temperature up to 60℃ on tensile and impact toughness properties of armour grade Q＆T steel welds were reported. The tensile and impact properties of the joints showed incremental trend with respect to the decrement in test temperature up to -40℃ irrespective of the welding processes used. The increment in tensile and impact properties of SmAW and FCAW joints subjected to the low temperature environment is due to plastic strain-induced phase transformation of retained austenite into martensite phase. Among the two processes, SmAW process welded joint showed better tensile and impact properties than its FCAW counterpart joints.

Integration of green chemistry principles to nanotechnology is one of the key issues in nanoscience research. The development of the concept of green nanoparticle preparation has been growingly needed for environmentally benign metal nanoparticle synthesis protocols to avoid adverse effects in medical applications. Keep this in mind, in the present study, silver nanoparticles were synthesized using Solanum lycopersicums fruit extract. The prepared silver nanoparticles were characterized by Uv-visible spectroscopy, Fourier transform infrared spectroscopy, Raman spectroscopy, scanning electron microscopy and transmission electron microscopy techniques. The surface plasmon resonance peak was found at 445 nm. The synthesized silver nanoparticles were spherical in shape with the average size of 10 nm. The citric acid present in S. lycopersicums fruit extract acted as reducing agent and malic acid was responsible for capping of the bioreduced silver nanoparticles.
