We have investigated magnetic moments of medium-weight and heavy N±1Λ hypernuclei within the framework of shell model. Using the perturbation theory, we have estimated the hyperon-induced configuration mixing effects as well as nucleon-induced configuration mixing effects on magnetic moments of these hypernuclei. The hyperon-induced configuration mixing effects turn out to be small in many cases.

The physical properties of ferrites are verysensitive to microstructure, which in turn critically dependson the manufacturing process.Nanocrystalline Lithium Stannoferrite system Li0.5+0.5XFe2.5-1.5XSnXO4,X= (0, 0.2, 0.4, 0.6, 0.8 and 1.0) fine particles were successfully prepared by double sintering ceramic technique at pre-sintering temperature of 500oC for 3 h andthepre-sintered material was crushed and sintered finally in air at 1000oC.The structural and microstructural evolutions of the nanophase have been studied using X-ray powder diffraction (XRD) and the Rietveld method.The refinement results showed that the nanocrystalline ferrite has a two phases of ordered and disordered phases for polymorphous lithium Stannoferrite.The particle size of as obtained samples were found to be ~20 nm through TEM that increases up to ~ 85 nmand isdependent on the annealing temperature. TEM micrograph reveals that the grains of sample are spherical in shape. (TEM) analysis confirmed the X-ray results.The particle size of stannic substituted lithium ferrite fine particle obtained from the XRD using Scherrer equation.Magneticmeasurements obtained from lake shore’s vibrating sample magnetometer (VSM), saturation magnetization ofordered LiFe5O8 was found to be (57.829 emu/g) which was lower than disordered LiFe5O8(62.848 emu/g).Theinterplay between superexchange interactions of Fe3+ ions at A and B sublattices gives rise to ferrimagnetic ordering of magnetic moments,with a high Curie-Weiss temperature (TCW ~ 900 K).

In 2020, the 75th anniversary of Victory in the Great Patriotic War was celebrated. Many soldiers and did not survive to see the end of the war. It is important that people living now remember and honor those who gave their lives for the freedom and independence of our country and those who came from the war in difficult conditions to restore the national economy of the country. In memory of those who courageously defended the independence of our great country, we named a new apple cultivar ‘Den Pobedy’ (Victory Day), which took 33 years to create. In 2020, this cultivar was included in the State Register of breeding achievements and it is recommended for cultivation in the Central-Chernozem region including Belgorod, Voronezh, Kursk, Lipetzk, Orel and Tambov regions. This cultivar was developed by crossing are quite commonly known winter cultivar ‘Veteran’ and foreign cultivar ‘Horcout’. Trees have a drooping crown. The main branches are curves. A characteristic feature of this cultivar is that the branches from the trunk depart at an angle close to straight. The main number of fruits is located on short fruit formations. Fruits are of medium weight (140 g), conical, wide-ribbed. The main color of the fruit at the time of harvest is greenish. The cover color occupies most of the surface of the fruit in the form of red blush. The fruit flesh is white, greenish of average density. The appearance (attractiveness) of the fruit is estimated at 4.4 points, and the taste - at 4.3 points (5-point rating). Fruits contain 14.7 % of sugars and 9.2 mg/100 g of ascorbic acid (vitamin C). Harvest in Orel region is in mid-September, the consumer period of fruits is until mid-March. The cultivar regularly bears fruit and has high product and consumer qualities.

Quantum Mechanical Approach

The discussion of the electron spin decoherence and relaxation phenomena via the hyperfine interaction with host lattice spins is presented here. The spin relaxation processes processes limit the conservation time of spin states as well as the response time of the spin system to external perturbations. The central spin model, where the spin of charge carrier interacts with the bath of nuclear spins, is formulated. We also present different methods to calculate the spin dynamics within this model. Simple but physically transparent semiclassical treatment where the nuclear spins are considered as largely static classical magnetic moments is followed by more advanced quantum mechanical approach where the feedback of electron spin dynamics on the nuclei is taken into account. The chapter concludes with an overview of experimental data and its comparison with model calculations.
