    Resonance Compression of Acoustic Beams in Crystals

    The resonant excitation of an intense elastic wave through nonspecular reflection of a special pump wave in a crystal is described. Geometric criteria are found under which mode conversion, when the incident and reflected beams belong to different acoustic branches, coexists with total internal reflection of an acoustic beam. In this case, the entire energy of an incident pump wave is spent on the excitation of a narrow intense reflected beam close in structure to an eigenmode. A consistent choice of orientations of the sagittal plane and crystal surface that excludes the reflection of a parasitic wave of leakage is found. The resonance parameters have been found for a medium with an arbitrary anisotropy. General relations are concretized for monoclinic, orthorhombic, trigonal, tetragonal, cubic, and hexagonal systems. Estimates and illustrations are given for a series of such crystals. The intensity of the reflected beam increases with its narrowing, but its diffraction divergence also increases with this narrowing. Nevertheless, the intensity of the beam can be increased by a factor of 5–10 at sufficiently high frequencies while keeping its divergence at an acceptable level. Amplification by two orders of magnitude can be achieved by compressing the beam in two dimensions through its double reflection

    Continuous Modeling of Arterial Platelet Thrombus Formation Using a Spatial Adsorption Equation

    In this study, we considered a continuous model of platelet thrombus growth in an arteriole. A special model describing the adhesion of platelets in terms of their concentration was derived. The applications of the derived model are not restricted to only describing arterial platelet thrombus formation; the model can also be applied to other similar adhesion processes. The model reproduces an auto-wave solution in the one-dimensional case; in the two-dimensional case, in which the surrounding flow is taken into account, the typical torch- like thrombus is reproduced. The thrombus shape and the growth velocity are determined by the model parameters. We demonstrate that the model captures the main properties of the thrombus growth behavior and provides us a better understanding of which mechanisms are important in the mechanical nature of the arterial thrombus growth

    Автор статьи рассматривает проблему профессиональной культуры журналиста с точки зрения создания единого профессионального стандарта. При этом показано, что данный стандарт должен учитывать и так называемых «непрофессионалов». Автор считает, что журналистское образование способно адаптировать представителей этой категории к требованиям журнализма. В качестве примера представлен собственный опыт создания и проведения тематического вебинара.The author analyzes the problem of journalist’s professional culture in terms of forming common professional standard. It is shown that this standard should also consider the group of “non-professionals”. The author believes that a journalistic education may help “non-professionals” to adapt to the journalism culture. As an example, the author shows his own experience of creating and organizing the thematic webinar

    Система журналистского образования в России сегодня часто подвергается критике со стороны студентов и журналистов. Одна из объективных проблем — неактуальность ряда методов преподавания журналистики. Автор статьи рассматривает воркшоп как один из альтернативных методов обучения, который имеет большой потенциал.Students and journalists often criticize the current system of journalism education in Russia. One of the objective problems is that some teaching methods used in journalism education are not relevant. The author discusses the workshop as an alternative teaching method that possesses big potential
