Unconventional phase transitions in strongly anisotropic 2D (pseudo)spin systems

We have applied a generalized mean-field approach and quantum Monte-Carlo technique for the model 2D S = 1 (pseudo)spin system to find the ground state phase with its evolution under application of the (pseudo)magnetic field. The comparison of the two methods allows us to clearly demonstrate the role of quantum effects. Special attention is given to the role played by an effective single-ion anisotropy (»on-site correlation»). © 2018 The Authors, published by EDP Sciences.The research was supported by the Government of the Russian Federation, Program 02.A03.21.0006 and by the Ministry of Education and Science of the Russian Federation, projects Nos. 2277 and 5719

Properties and Biocompatibility of Colloid Cadmium Sulfide Nanoparticles

This work is devoted to the synthesis of CdS nanoparticles stabilized by EDTA and to the study of the biological effect of colloidal CdS nanoparticles on cell cultures.Работа выполнена в соответствии с государственным заданием Института химии твердого тела УрO РАН по теме №. 0397-2019-0001

RADIATION-INDUCED ADAPTIVE RESPONSE OF HELA CELLS AND DERMAL HUMAN FIBROBLAST

In the work, we investigate the adaptive response of Hela cells and dermal human fibroblast on exposure of LDR. The culture cells were irradiated on an Xstrahl 300, which produces X-rays with 200 keV energy. Studies have shown that adaptive response induced by Low-dose radiation (LDR) is manifested in DHF cells. LDR does not induce the radioadaptive response in tumoral Hela cells. We have found an increase in the radiosensitivity to ionizing radiation in Hela cells

Influence of insulin on morphological characteristics of breast carcinoma cells in culture

The effect of insulin on the polymorphism of cultured breast carcinoma cells, which manifests itself in changes in the morphological parameters of cells in culture over several passages, has been establishedУстановлено влияние инсулина на полиморфизм культивируемых клеток карциномы молочной железы, проявляющихся в изменении морфологических показателей клеток в культуре на протяжении нескольких пассаже

Аминокислотный состав яиц кур как показатель ассимиляционных процессов в их организме при использовании в рационе антиоксидантного препарата

The paper highlights the results of the experiment conducted at the Simbirsk poultry farm of Ulyanovsk region. The researchers arranged two similar groups of laying hens. Each group contained 364 laying hens. The hens were fed with the same full-feed fodder, but the hens from the experimental group received Lipovitam Beta by means of stepwise mixing method.   The specimen contains  β-carotene, vitamin C, vitamin E, butyloxyanisole, phospholipids 240 grams per 1 t of mixed fodder. The authors prove the efficiency of using liposomal form of the antioxidant vitamin complex “Lipovitam Beta” when feeding laying hens in order to enhance the antioxidant system and, therefore, assimilation processes. These processes contribute to better synthesis of protein in the body of laying hens and higher concentration of protein in the blood serum by means of albumins, globulins and higher protein concentration in the egg..  Application of the specimen  in the compound feed contributes to longer egg-laying peak (from 97 to 102 days) and egg-laying capacity (by 22.87 and 18.25 eggs), better amino acid composition of eggs, their amino acid scores, which indicates their higher biological and nutritional value.Представлены результаты экспериментальных исследований, проведенных в условиях Симбирской птицефабрики Ульяновской области на двух аналогичных группах курнесушек по 364 головы в каждой. Кормление несушек проводилось одним и тем же полнорационным комбикормом, но в состав его для птицы опытной группы вводили методом ступенчатого смешивания препарат «Липовитам Бета», содержащий в своем составе β-каротин, витамин С, витамин Е, бутилоксианизол, фосфолипиды из расчета 240 г на 1 т комбикорма. Доказана целесообразность использования в кормлении кур-несушек липосомальной формы антиоксидантного витаминного комплекса «Липовитам Бета» для усиления действия антиокислительной системы, а следовательно, и ассимиляционных процессов, проявившихся в увеличении синтеза белка в их организме, что нашло отражение в его большей концентрации в сыворотке крови за счет альбуминов и глобулинов и большего содержания белка в яйце. Использование в составе комбикорма изучаемого препарата способствует повышению продолжительности пика яйцекладки (с 97 до 102 дней) и уровня яйценоскости (на 22,87 и 18,25 шт.), улучшению аминокислотного состава яиц, их аминокислотного скора, что свидетельствует об их повышенной биологической и пищевой ценности

Strongly Anisotropic S=1 (Pseudo) Spin Systems: from Mean Field to Quantum Monte-Carlo

The S=1 pseudospin formalism was recently proposed to describe the charge degree of freedom in a model high-T_{c} cuprate with the on-site Hilbert space reduced to the three effective valence centers, nominally Cu^{1+;2+;3+}. With small corrections the model becomes equivalent to a strongly anisotropic S=1 quantum magnet in an external magnetic field. We have applied a generalized mean-field approach and quantum Monte-Carlo technique for the model 2D S=1 system to find the ground state phase with its evolution under deviation from half-filling and different correlation functions. Special attention is given to the role played by the on-site correlation ("single-ion anisotropy")

Sorption-probiotic supplement in the diet of calves and its effect on the functional maturity of their rumen, morpho-biochemical blood status and productivity

This research considers the use of the sorption-probiotic supplement Biopinnular in the amount of 0.5 and 1.0 % of the dry matter in the diets of calves of the dairy period. The results allows us to correct the microbiocenosis in the in the digestive tract by suppressing the development of pathogenic microflora and increased reproduction of Lacto- and Bifido bacteria. The studied supplement also contributes to deeper fermentation of fodder mass during digestion in the rumen, which is manifested in an increase in active acidity (pH), cellulolytic activity of bacteria, VFA content as the main product of carbohydrate fermentation, as well as enhanced ammonia-binding function of microflora, which led to better energy and protein availability of their body. This is confirmed by indicators of the morphological and biochemical status of the blood of calves, manifested in a real increase in their red blood cells, hemoglobin, protein and protein fractions. All this was confirmed by the intensity of their live weight gain, accompanied by large average daily (by 8.83 and 23.70 %, respectively) and relative (by 1.63 and 3.86 %) weight gains and smaller (by 0.44 and 0.64) EFU costs per unit of live weight gain. A more pronounced biological effect is observed when using a feed supplement at a dose of 1.0 % of the dry matter of the diet
