Functions of the complex and methodological principles of its development are considered, comparison with foreign analogues is carried out. The model of the industrial analytical control with use of concepts of a life cycle of a laboratory, technique and test is described

Theory of magnetoelastic resonance in a mono-axial chiral helimagnet

We study magnetoelastic resonance phenomena in a mono-axial chiral helimagnet belonging to hexagonal crystal class. By computing the spectrum of coupled elastic wave and spin wave, it is demonstrated how hybridization occurs depending on their chirality. Specific features of the magnetoelastic resonance are discussed for the conical phase and the soliton lattice phase stabilized in the mono-axial chiral helimagnet. The former phase exhibits appreciable non-reciprocity of the spectrum, the latter is characterized by a multi-resonance behavior. We propose that the non-reciprocal spin wave around the forced-ferromagnetic state has potential capability to convert the linearly polarized elastic wave to circularly polarized one with the chirality opposite to the spin wave chirality.Comment: 12 pages, 5 figures, Accepted in Phys.

Ecological education: problems and solutions

Among the main tasks we should point out the creation of systematic ecological education and public informing about the environment, the influence on it from the side of different subjects and methods of their improvement in. Nowadays ecology is a discipline that unites humanitarian and natural sciences and helps to form the general model of relations between nature, society and from another side it defines the sense and development perspectives for all humanity.

What makes minority ethnic teachers stay in teaching, or leave?

This briefing note considers the findings of the BA/Leverhulme-funded research project ‘Retention of teachers from minority ethnic groups in disadvantaged schools’ on the retention factors for teachers from minority ethnic groups and outlines some implications for schools. There is a gap between the proportion of teachers and students from ethnic minority backgrounds in England. In 2019, 86% of all teachers were from a White British background, compared to 65% of pupils (UK Government, 2020). While efforts to recruit new teachers from minority ethnic backgrounds are important, these alone will not resolve the shortage. Nationally, retention is lower for minority ethnic teachers than for White British teachers (DfE, 2018). Understanding the retention of minority ethnic teachers is vital in addressing the imbalance between the proportion of teachers and pupils from minority ethnic backgrounds in teaching. The findings are based on interviews with 24 teachers, including 14 Black teachers, two mixed White and Black heritage teachers and eight teachers from different Asian backgrounds. Thirteen of these teachers were in the profession for over five years and nine for five or less years. Nine participants worked in primary and 15 in secondary schools (for details see Tereshchenko et al., 2020). Some of the factors affecting minority ethnic teacher retention are the same as those affecting teachers of majority background. Unsurprisingly, teachers are happiest in those schools where they feel valued, respected, have autonomy, connection with, and support from, colleagues and senior leaders, and clear paths for career progression. Our research has shown that some experiences affecting retention apply specifically to minority ethnic teachers

Improving the retention of minority ethnic teachers in England. Policy Briefing from the Centre for Teachers & Teaching Research

Despite the ongoing policy commitment to diversification of the teaching workforce (DfE, 2018a), a gap persists between the proportion of students and teachers from minority ethnic groups in England. Figures from 2019 show that 85.6% of all teachers and 65.4% of pupils are currently from a White British background; in comparison, 78.5% of the working age population of England were recorded as White British in the 2011 census (UK Government, 2020). Efforts to recruit new teachers from minority ethnic groups are important but these alone will not solve shortages. Nationally, retention is lower for minority ethnic teachers than for White British teachers (DfE, 2018b). Teachers from minority ethnic groups also experience unique problems linked to racial inequality and racism in their careers (Haque & Elliott, 2017). Yet, there has been little empirical investigation of how the ethnic character of the English teaching workforce has changed over time, where minority ethnic teachers tend to be employed, and what happens to these teachers once they are employed that causes lower retention

Conductance oscillations and zero-bias anomaly in a single superconducting junction to a three-dimensional Bi2Te3Bi_2Te_3 topological insulator

We experimentally investigate Andreev transport through a single junction between an s-wave indium superconductor and a thick film of a three-dimensional $Bi_2Te_3$ topological insulator. We study $Bi_2Te_3$ samples with different bulk and surface characteristics, where the presence of a topological surface state is confirmed by direct ARPES measurements. All the junctions demonstrate Andreev transport within the superconducting gap. For junctions with transparent $In-Bi_2Te_3$ interfaces we find a number of nearly periodic conductance oscillations, which are accompanied by zero-bias conductance anomaly. Both effects disappear above the superconducting transition or for resistive junctions. We propose a consistent interpretation of both effects as originating from proximity-induced superconducting correlations within the $Bi_2Te_3$ topological surface state

VHF scintillations, orientation of the anisotropy of F-region irregularities and direction of plasma convection in the polar cap

Scintillation data recorded at the polar cap station Barentsburg are shown to occasionally exhibit two or more peaks in the latitudinal profiles of the amplitude dispersion. Comparison with concurrent SuperDARN radar convection maps indicates that multiple peaks occur when Barentsburg is located within the area of strong changes in the plasma flow direction. When parameters of the ionospheric irregularities are inferred from the scintillation data, the orientation of the irregularity anisotropy in a plane perpendicular to the magnetic field is found to coincide well with the <I><b>E</b></I>×<I><B>B</B></I> flow direction, individually for each peak of the scintillation data. The differences were found to be mostly less than 20° for a data set comprised of 104 events. The conclusion is made that analysis of scintillation data allows one to infer the direction of plasma flow with a certain degree of detail
