Technology of forecasting in the professional activity of future applicants for higher pedagogical education

The article identifies the need for the formation of prognostic competence of applicants for higher pedagogical education in accordance with the requirements of the concept of development of pedagogical education and professional standard. The authors propose a structural scheme of forecasting activities, define the concept, purpose, objectives of the course "Technology of forecasting in professional activities" and provide guidelines for the study of individual topics based on theoretical predictions. As part of the course, students of higher pedagogical education master the technology of introducing educational forecasting on the example of educational activities in physics. Educational forecasting is defined in the course as a specially organized cognitive process by the teacher, as a result of which students on the basis of theoretical knowledge predict phenomena and facts unknown to them. Particular attention in the study of the course is paid to the structure of theoretical predictions based on the deductive study of the structural components of physical knowledge and on the basis of inductive generalizations from experiments. The article presents examples of studying the phenomenon of electric resonance, the law of inertia, the characteristics of the electrostatic field based on prediction. The idea of developing students' ability to think hypothetically is the central idea of the course. Applicants for higher pedagogical education during the study of the course gain confidence that the process of constructing a hypothesis based on theoretical models is especially valuable for the development of hypothetical thinking. The article presents the results of research conducted during the study of the course on the problem of organizing the educational activities of students by teachers on the basis of forecasting. The research results confirm the relevance, necessity and expediency of the proposed course not only for applicants for higher pedagogical education, but also for further professional development of teachers of natural sciences and mathematics, namely the development of prognostic competence.

Contactless Excitation of Piezoelectric Device through Curvilinear shaped Electric Field Generator

Contactless excitation of piezoelectric (PZT) component through focused E-field has been investigated in this work. In the intended technique, E-field is focused to ground electrode from a curvilinear-shaped potential electrode so that maximum E-field can penetrate sufficiently through PZT component which is positioned inbetween the electrodes. Simulation analysis shows that the contactless energization of PZT component is due to electric resonance as well as piezo-electric resonance. The maximum vibration occurs across the PZT components when the E-field generator operating frequency (f0 ) matches with the mechanical resonance frequency (fm). The max output power across the contactless energized PZT component mainly rely on operating frequency, resonance, position & resistive load. The output power achieved across the contactless excited PZT component by focused E-field generator is higher than the output power achieved across the contactless excited PZT component by capacitor like E- field generator. The max output power of 9.9mW is obtained across PZT component at 1295 kHz resonance frequency (fr ) and 19.5 kΩ optimum loads with an input of 50 V and 8 mm electrode separation. By enactment of this excitation methods provide free actuation of PZT component so as to overcome the difficulties associated with the confined motion for different applications.

Polarizability Extraction of Above-Half-Space Transversal Dipole Scatterers Using a Fast Waveguide-Based Approach

We present a semi-analytical method to extract transverse polarizability parameters of an arbitrary bi-anisotropic sub-wavelength scatterer both in homogeneous medium and placed at the boundary of two simple (homogeneous, isotropic, and linear) media. Using this technique, polarizability parameters of various dielectric and/or metallic scatterers are obtained, effectively. In this method, a scatterer is placed at the middle of a rectangular waveguide which in general is filled by two different simple media in either sides of the scatterer. The waveguide is designed so that the two TE10 and TE01 fundamental modes are propagating in a given frequency band. All 16 transverse polarizabilities are fast obtained having 16 different generalized scattering parameters (S-parameters). The S-parameters are associated with excitations at two different ports of the waveguide and the two different modes (TE10 and TE01). Comparing to existing polarizability extraction methods, the presented waveguide method is easy to run, fast and almost accurate. In order to validate the method, we present three examples including omega particle and magneto-dielectric sphere in free-space and an electric resonance particle, placed on top of a dielectric half-space.

Water-Related Mechanisms Proposed for Storing and Transmitting Homeopathic Information: Putative Links with Biological Responses

Introduction There are two critical pillars of homeopathy that contrast with the dominant scientific approach: the similitude principle and the potentization of serial dilutions. Three main hypotheses about the mechanisms of action are in discussion: nanobubbles-related hormesis; vehicle-related electric resonance; and quantum non-locality. Objectives The aim of this paper is to review and discuss some key points of such properties: the imprint of supramolecular structures based on the nanoparticle-allostatic, cross-adaptation-sensitization (NPCAS) model; the theory of non-molecular electromagnetic transfer of information, based on the coherent water domains model, and relying (like the NPCAS model) on the idea of local interactions; and the hypothesis of quantum entanglement, based on the concept of non-locality. Results and Discussion The nanoparticles hypothesis has been considered since 2010, after the demonstration of suspended metal nanoparticles even in very highly diluted remedies: their actual action on biological structures is still under scrutiny. The second hypothesis considers the idea of electric resonance mechanisms between living systems (including intracellular water) and homeopathic medicines: recent findings about potency-related physical properties corroborate it. Finally, quantum theory of ‘non-local’ phenomena inspires the idea of an ‘entanglement’ process among patient, practitioner and the remedy: that quantic phenomena could occur in supra-atomic structures remains speculative however. Conclusion Further studies are needed to ascertain whether and which of these hypotheses may be related to potential cellular effects of homeopathic preparations, such as organization of metabolic pathways or selective gene expression.
