El papel de la educación continua en la formación de habilidades profesionales en el proceso de entrenamiento de manejo individual
This article presents solutions that are defined as a paradigm shift in driving schools, which will allow restructuring the process of driver training and reducing the risk of accidents. Thus, the study discusses ways to reduce the accident rate of drivers who have recently received a license to drive a car. To achieve the goal, accident statistics were analysed depending on driving experience and driver age. The influence of the Internet and computer games on the psychology of novice drivers was also studied. Finally, the process of driving skills formation in the entrepreneurial educational process of driving schools is described. We suggested that novice drivers should demand the proper driving school and consider the criteria by which they can choose a suitable and effective driving school to obtain complete and in-depth knowledge.Este artículo presenta soluciones que se definen como un cambio de paradigma en las autoescuelas, lo que permitirá reestructurar el proceso de capacitación de conductores y reducir el riesgo de accidentes. Por lo tanto, el estudio analiza formas de reducir la tasa de accidentes de los conductores que recientemente recibieron una licencia para conducir un automóvil. Para lograr el objetivo, se analizaron las estadísticas de accidentes según la experiencia de conducción y la edad del conductor. También se estudió la influencia de Internet y los juegos de computadora en la psicología de los conductores novatos. Finalmente, se describe el proceso de formación de habilidades de conducción en el proceso educativo emprendedor de las escuelas de conducción. Sugerimos que los conductores novatos deben exigir la escuela de manejo adecuada y considerar los criterios por los cuales pueden elegir una escuela de manejo adecuada y efectiva para obtener un conocimiento completo y profundo
Master Higher-Spin Particle
We propose a "master" higher-spin (HS) particle system. The particle model
relevant to the unfolded formulation of HS theory, as well as the HS particle
model with a bosonic counterpart of supersymmetry, follow from the master model
as its two different gauges. Quantization of the master system gives rise to a
new form of the massless HS equations in an extended space involving, besides
extra spinorial coordinates, also a complex scalar one. As solutions to these
equations we recover the massless HS multiplet with fields of all integer and
half-integer helicities, and obtain new multiplets with a non-zero minimal
helicity. The HS multiplets are described by complex wave functions which are
holomorphic in the scalar coordinate and carry an extra U(1) charge q. The
latter fully characterizes the given multiplet by fixing the minimal helicity
as q/2. We construct a twistorial formulation of the master system and present
the general solution of the associate HS equations through an unconstrained
twistor "prepotential".Comment: 21 pages, minor corrections, version to appear in Class. Quantum Gra

Multiple effects of bariatric surgery on human biochemical status
Beneficial effect of bariatric surgery is expressed not only in reducing body weight, but also in improving the functioning of the body as a whole. On the one hand, numerous studies devoted to the investigations of specific mechanisms of the influence of bariatric surgery on the general condition of an organism testify to the enormous interest of scientists in this problem. On the other hand, the range of changes is so vast that it covers almost all physiological and biochemical processes. The most noticeable response to bariatric surgery is from the digestive (including the composition of the microbiota), immune (reducing the level of systemic and local inflammation), cardiovascular (reducing the risks of atherosclerosis and other diseases) systems. Partial or complete compensation of type 2 diabetes mellitus and metabolic syndrome also occurs. Among the variety of data, there is insufficient research on only standard biomarkers: leptin, C-reactive protein, interleukin 6, etc. A detailed study of the profiles of both circulating biomarkers and local ones is necessary. At the same time, it is obligate to continue to accumulate evidence on the positive effect of bariatric surgery, since this type of surgical intervention has come into practice relatively recently. Unfortunately, at the present time in Russia bariatric surgery is not an affordable and popular treatment for morbid obesity (MO). Nevertheless, it is extremely important to change the current situation, since bariatric treatment is an optimal and effective solution to socially significant diseases such as MO or type 2 diabetes mellitus

Temperature- and field-induced transformation of the magnetic state in Co2.5Ge0.5BO5
A tetravalent-substituted cobalt ludwigite Co2.5Ge0.5BO5 has been synthesized using the flux method. The compound undergoes two magnetic transitions: a long-range antiferromagnetic transition at TN1 = 84 K and a metamagnetic one at TN2 = 36 K. The sample-oriented magnetization measurements revealed a fully compensated magnetic moment along the a- and c-axes and an uncompensated one along the b-axis leading to high uniaxial anisotropy. A field-induced enhancement of the ferromagnetic correlations at TN2 is observed in specific heat measurements. The DFT+GGA calculation predicts the spin configuration of (↑↓↓↑) as a ground state with a magnetic moment of 1.37 μB/f.u. The strong hybridization of Ge(4s, 4p) with O (2p) orbitals resulting from the high electronegativity of Ge4+ is assumed to cause an increase in the interlayer interaction, contributing to the long-range magnetic order. The effect of two super–superexchange pathways Co2+-O-B-O-Co2+ and Co2+-O-M4-O-Co2+ on the magnetic state is discussed.This work has been financed by the Russian Foundation for Basic Research (project no. 20-02-00559).
