Parity splitting in nuclei involving octupole correlations and the alignment of the angular momentum

A rotational model based on a simultaneous analysis of parity splitting and the alignment of the angular momentum is developed to describe high-spin negative-parity states. A simple formula for the energy of these states is proposed. It is shown that negative-parity states exhibit alignment, provided that the ground-state band is aligned and that the two opposite-parity bands can be considered as a single alternating-parity band. © 2001 MAIK "Nauka/Interperiodica"

Double reversal of parity sign in alternating-parity rotational band

Parity sign reversal in the alternating-parity rotational band is observed in the spectrum of light isotopes of actinide nuclei, and in some nuclei double reversal takes place. Double reversal in the 220-226Ra isotopes is described within the high-spin approximation of the rotational model on the basis of Coriolis interaction between states showing parity splitting and angular momentum alignment. © 2007 by Allerton Press, Inc

Backbending and GammaGamma-Vibrations

We propose that the backbending phenomenon can be explained as a result of the disappearance of collective $gamma$-vibrational mode in the rotating frame. Using a cranking+random phase approximation approach for the modified Nilsson potential + monopole pairing forces, we show that this mechanism is responsible for the backbending in $^{156}$Dy, $^{158}$Er and obtain a good agreement between theoretical and experimental results.Comment: 5 pages, 4 figures, published versio

Influence of angular momentum alignment on high-spin states of positive and negative parity in 162Yb nucleus

Experimental data for the 162 Yb nucleus were analyzed and energy and radiation features in the presence of intrinsic angular momentum alignment were theoretically described within the phenomenological model of Coriolis mixing of high-spin bands. © 2007 by Allerton Press, Inc

Influence of octupole interactions on the behavior of negative-parity states at low spins

The energies of negative-parity levels based on two-particle states exhibit a nonlinear behavior at low spins versus the core-rotation energy because the alignment process has not yet been completed for them. This behavior of negative-parity levels in the low-spin region is satisfactorily described upon the inclusion of octupole-octupole interactions. This is demonstrated within the rotational model involving the Coriolis mixing of states for the even-even isotopes 162-168Hf. © Nauka/Interperiodica 2006

SOLUTION OF THE PROBLEM IN THE DRYING OF FLAT INFRARED HEATING MATERIAL LAYER AT STATIONARY MOISTURE TRANSFER

Nonlinear process when the moisture has a stationary position from the point of the analytical research is needed for theoretical and applied problems. In this paper we investigate the distribution of the heat provided stationary moisture where heat distribution has a pattern differs from the linear interaction between moisture and heat. Permanence moisture sampling is the result of a relatively steady drying mode. In the drying chamber we have a closed volume, it is particularly noticeable for the vacuum chambers, and therefore there is almost stationary process between stable heating and evaporation. Obtained linear problem of parabolic type to accomplish this task with the appropriate boundary conditions, we can apply for the interval (0, l), separation of variables. The solution for linear and non-linear interaction of moisture and temperature in the case of stationary moisture have a predetermined temperature field as a result of solution of the nonlinear system that is needed to assess the effect of non-linearity which clearly identifies with a solution.Nonlinear process when the moisture has a stationary position from the point of the analytical research is needed for theoretical and applied problems.

Yorug’lik fotokatalitik faolligi yaxshilangan PANI/TIO2 kompozitsiyasi

Polianilin (PANI) ko’rinadigan yorug’lik va fotokatalitik samaradorlikni oshirish uchun kengaytirilgan fotoreaktivlikka erishish uchun TiO2 sirtini modifikatsiyalash uchun istiqbolli o’tkazuvchan polimerdir. Ushbu tadqiqotda biz ko’rinadigan yorug’lik nurlanishi ostida metilen ko’k (MB), bisfenol A (BPA) va bakteriofag MS2 ning fotokatalitik degradatsiyasi uchun ishlatilgan PANI ning turli vazn nisbatlariga ega PANI/TiO2 kompozitsiyasining sintezi haqida xabar beramiz. Kompozitning funktsional guruhlari, morfologiyasi va yorug’lik reaktsiyasi Furye-transform infraqizil spektroskopiya, dala-emissiya uzatuvchi elektron mikroskopiya va diffuz aks ettiruvchi UV- ko’rinadigan spektroskopiya bilan tavsiflangan. Og’irlik nisbati bo’yicha 4% PANI o’z ichiga olgan PANI/TiO2 kompozitsiyasi MB degradatsiyasi uchun eng mos edi va bu fotokatalizator takroriy foydalanishdan keyin ham (to’rt sikl) juda barqaror edi. BPA va bakteriofag MS2 ning PANI/TiO2 kompozitsiyasi bilan parchalanishi ko’rinadigan yorug’lik nurlanishida mos ravishda 360 daqiqada 80% va 120 daqiqada 96,2% ga yetdi. Shu sababli, ko’rinadigan yorug’lik fotokatalitik samaradorligi va barqarorligi yaxshilangan PANI/TiO2 kompozitsiyasi suvni ifloslantiruvchi moddalarning degradatsiyasi uchun keng qo’llanilishi mumkin

Electron irradiation: from test to material tayloring

In this article, we report some examples of how high-energy electron irradiation can be used as a tool for shaping material properties turning the generation of point-defects into an advantage beyond the presumed degradation of the properties. Such an approach is radically different from what often occurs when irradiation is used as a test for radiation hard materials or devices degradation in harsh environments. We illustrate the potential of this emerging technique by results obtained on two families of materials, namely semiconductors and superconductors

Clinical-Epidemiological Features of Eczema of the Skin in Uzbekistan (on the Example of the Tashkent Region).

Justification. Eczema of the skin is recognized as a major health problem worldwide. Prevalence estimates reach one third of the population, depending on the country studied, the age range of the subjects and the diagnostic criteria used. The aim is to assess the nature of epidemiological and clinical manifestations of eczema of the skin in Uzbekistan. Results. The data of the population register of eczematous skin diseases, created on the basis of the Tashkent regional skin-venereological dispensary, have been studied.  Retrospective analysis of stories for the period 2019-2023. conducted on the clinical basis of the department «Dermatovenereology and cosmetology» of the Tashkent Medical Academy. Conclusion. The prevalence of skin eczema among the general population of the Tashkent region from 2019 to 2023. It has increased reliably, especially in the age group of years.  Eczema is more common among men, with an earlier onset of the disease (the age group under age).  The most common clinical form is true skin eczema
