Authors: Besharat Hilda , Khavari-Nejad Ramazan Ali , Mahmoodzadeh Homa , Nejad Shahrokh Abadi Khadijeh
Published: March 2021

The production, growth, and physiological processes of plants respond differently to the varying concentrations of nanoparticles. Due to the increasing importance and application of nanoparticles, it is essential to determine the impact on plants physiological systems. Therefore, this study investigated the effect of different bulk and nano nickel oxide concentrations on biomass production and the enzymatic system of fennel. The experiment was carried out in a completely randomized design with the applications of 5 replications and 5 concentrations (0, 20, 100, 400, and 800 ppm) in the greenhouse of the Faculty of Science, Mashhad Branch, Islamic Azad University. This study analyzed various plants traits, including shoot and dry root weight and a few antioxidant enzymes. The results showed that root and shoot dry weight were not affected by the applied treatments. Furthermore, all applied levels of treatment significantly increased the activity of fennel leaf polyphenol oxidase compared to the control. The bulk treatment at 800 ppm was exempted, where the application of bulk nickel oxide and nanoparticles decreased dehydrogenase enzyme activity. In addition, the activity of guaiacol peroxidase increased under all levels of treatments except 100 ppm nanoparticles. The highest amount of phenylalanine ammonia-lyase activity was obtained under 20 ppm treatment with a 61.98% increase compared to the control method. Furthermore, nickel oxide treatments also increased MDA. The results showed that nanomaterials' toxicity, caused oxidative stress in this plant, and the differences in MDA content of leaves explained the higher toxicity of NiO nanoparticles than bulk form. Moreover, higher activity of leaf antioxidative enzymes in bulk NiO2 treatments, especially Guaiacol Peroxidase, explained the plant's higher resistance to oxidative stress.
À MARGEM DA LEI: PRÁTICAS CULTURAIS NA AMAZÔNIA ACREANA
Authors: Albuquerque Gerson Rodrigues
Published: March 2021

Desde a última década do século XX, algumas práticas culturais e a própria sobrevivência de comunidades de mulheres e homens da região do Vale do Juruá, na Amazônia acreana passaram a ser impactadas pela ação de determinados agentes públicos que, em nome de instituições de proteção ambiental, a partir de diligências e relatos de fiscalização, operacionalizam uma verdadeira criminalização dos modos de vida de populações secularmente habitantes da floresta e de suas entidades representativas. Com base nesses relatos e em trechos de processos criminais ou administrativos, tendo como pano de fundo a relação linguagem e cultura, no âmbito deste artigo, procura-se problematizar a produção discursiva que reduz diferentes comunidades de habitantes da floresta em “criminosos ambientais”, silenciando suas vozes e marginalizando suas culturas.
SABORES DA PAN-AMAZÔNIA: UMA LEITURA DE RECETUARIO AMAZÓNICO DE DIOS (2002), DE NICOMEDES SUÁREZ ARAÚZ
Authors: Marques Gracielle
Published: March 2021

A preocupação com a devastação ecológica da região amazônica é uma dos eixos centrais do livro de poemas Recetuario Amazónico de Dios (2002), do poeta e crítico boliviano Nicomedes Suárez Araúz, que recria as receitas familiares misturando ingredientes culinários com a paisagem, as populações indígenas, a história e algumas pitadas de ironia. Com o intuito de abordar como as relações entre poesia, história e ecologia são representadas no referido livro, realiza-se um breve comentário do percurso literário do autor, passando por sua concepção estética da Amnésia, em seguida apresenta-se suas contribuições com a visão literária pan-amazônica e, por fim, analisa-se alguns poemas, focalizando os elementos de suas composições que propiciam o desvelar de um fazer literário crítico em relação à natureza e à alteridade, com embasamento nos Estudos Descoloniais (QUIJANO, 2005) e na Ecocrítica (GARRARD, 2006).
O ROMANCE OS ANÕES: A AMAZÔNIA SOB A SÁTIRA DE HAROLDO MARANHÃO
Authors: Oliveira Elisangela Ribeiro , Nascimento Maria de Fatima Do
Published: March 2021

O presente artigo discute a sátira no romance Os anões (1983), do escritor paraense Haroldo Maranhão. A referida obra sugere a pauta dos grandes projetos desenvolvimentistas propostos pelos governos militares para a região amazônica do Brasil entre as décadas de 1970 e 1980, especialmente na Amazônia paraense. Vale ressaltar que é pelo discurso jocoso e indignado da sátira que Haroldo Maranhão denuncia os piores problemas enfrentados pelos paraenses e belenenses, ou seja, o descaso dos governos com a população do Pará e com o espaço amazônico, bem como a exploração de riquezas naturais e da força de trabalho do homem local, a supervalorização das aparências e a busca incessante pelo poder, seja econômico, social ou político, que maculam as instituições brasileiras, a saber: a igreja, a família, a justiça e a política.
“Deixe-me entrar”, “deixe-me sair”: uma janela entre O morro dos ventos uivantes, de Emily Brontë e Vulgo Grace, de Margaret Atwood
Authors: Gonçalves de Souza Santos Natália
Published: March 2021

Este artigo propõe uma aproximação entre duas obras que podem ser alocadas dentro da tradição literária gótica: O morro dos ventos uivantes (1847), da autora inglesa Emily Brontë e Vulgo Grace (1996), da autora canadense Margaret Atwood. A partir da identificação de um diálogo intertextual, discute-se a presença da metáfora da janela em ambas as obras, compreendida como espécie de tópica literária que representa o caráter limiar das personagens, esmagadas por uma série de interditos. A janela também pode figurar como possibilidade de fuga, por vezes, concretizada apenas com o auxílio do sobrenatural. Argumenta-se que a presença dessa metáfora em romances de épocas distintas sugere tanto o necessário e produtivo processo de apropriação da herança literária, quanto a permanência de medos e tiranias do passado no presente, fazendo com que a narrativa gótica possa ser vista como espaço de resistência para mulheres.

While Roux-en-Y gastric bypass (RYGB) surgery in obese individuals typically improves glycemic control and prevents diabetes, it also frequently causes asymptomatic hypoglycemia. Previous work showed attenuated counterregulatory responses following RYGB. The underlying mechanisms as well as the clinical consequences are unclear. In this study, 11 subjects without diabetes with severe obesity were investigated pre- and post-RYGB during hyperinsulinemic normo-hypoglycemic clamps. Assessments were made of hormones, cognitive function, cerebral blood flow by arterial spin labeling, brain glucose metabolism by 18F-fluorodeoxyglucose (FDG) positron emission tomography, and activation of brain networks by functional MRI. Post- versus presurgery, we found a general increase of cerebral blood flow but a decrease of total brain FDG uptake during normoglycemia. During hypoglycemia, there was a marked increase in total brain FDG uptake, and this was similar for post- and presurgery, whereas hypothalamic FDG uptake was reduced during hypoglycemia. During hypoglycemia, attenuated responses of counterregulatory hormones and improvements in cognitive function were seen postsurgery. In early hypoglycemia, there was increased activation post- versus presurgery of neural networks in brain regions implicated in glucose regulation, such as the thalamus and hypothalamus. The results suggest adaptive responses of the brain that contribute to lowering of glycemia following RYGB, and the underlying mechanisms should be further elucidated.

Aerobic Energy Contribution during High Intensity Exercise
Authors: CHIA Michael
Published: March 2021

LANGUAGE NOTE | Document text in English; abstract also in Chinese.The review focuses on the aerobic energy contribution during high intensity cycling exercise. It is erroneous to assume that the energy demands of an exercise task can be met exclusively by either aerobic or anaerobic sources. During peak oxygen uptake determination, especially during the latter portions of the incremental exercise test, the anaerobic energy stores are also taxed. Not surprising, during maximal exercise of a short duration, there is also energy supplementation from aerobic energy sources. However, for a test to be considered predominantly anaerobic, the aerobic contribution to the test must be kept minimal. The quantification of aerobic contribution to a maximal exercise performance is difficult because the mechanical efficiency (ME) during a non-steady state exercise task remains speculative. Nevertheless extreme ME values for cycling have been proposed to provide a general scope of the estimated values. In adults, assumptions about oxygen uptake lag time, the size and role of the stored oxygen stores, which are taken into account also affect the magnitude to the aerobic contribution. Equivalent data on young people are insecure and greater research attention in this area is advised.本文著重介紹了大強度自行車運動中的有氧供能。如果認為運動中機體所需能量僅以某一能源系統，有氧系統或無氧系統供能是不正確的。在逐級遞增負荷測定最大攝氧量的運動中，尤其在測試的後階段，無氧系統參與供能。而在短時間的最大強度運動中，有氧供能也佔有一定的比例。即使進行無氧運動，在測試中仍能發現有低比例有氧供能。很難確定有氧系統在最大強度運動中的供能量為多少，因為不穩定狀態下的運動其供能效率仍不十分明確。但對於踏車運動中最高供能效率有一估計值範圍。對於成年人，攝氧量的延遲時間以及氧的儲存量的多少將影響最大有氧供能的比例。而在青少年中：有關這方面的資料較為缺乏，有待進一步的研究。

Authors: HSU Chin Hsing , TSAO Te Hung , SHU Shiou Tau , YANG Chang Bin
Published: March 2021

LANGUAGE NOTE | Document text in English; abstract also in Chinese.
Purpose: In this study, we examined different regular exercisers’ abdominal fat distribution and relationships between serum leptin levels and the abdominal fat distribution. In addition, determining whether the waist (WC) and hip circumferences (HC) were related to the abdominal fat distribution in regular exercisers was another goal of this study. Method: runners (R, n=12) and swimmers (S, n=9), who exercised at least 5 times/week for 30 minutes/time and for at least 3 years, participated in this study. In addition, sedentary individuals (n=10), who exercised less than once/week and > 30 minutes/per time, served as a control group (C). All participants had a magnetic resonance imaging (MRI) scan for the abdominal fat distribution, blood analysis for leptin and measurements of WC, HC and body-mass index (BMI). Results: On the basis of BMI-matching, the R group’s abdominal visceral fat (0.4±0.3L) was less than those of the S and C groups (0.8±0.2L and 0.9±0.3L, respectively), and no significant differences in abdominal subcutaneous fat or serum leptin levels were evident among these three groups. The relationships between serum leptin and the abdominal fat distribution differed in the R and S groups. In the measurement of body circumference and abdominal fat distribution, WC was significantly related to abdominal subcutaneous fat among the three groups. Conclusions: Taking regular exercise can cause a decrease in the visceral fat accumulation, especially for people who are regular runners. The WC can be used to predict the abdominal subcutaneous fat of exercisers. Further studies are required in the future to determine the contribution of abdominal fat to serum leptin in exercisers.

Crossovers induced by discrete-time quantum walks
Authors: Chisaki Kota , Konno Norio , Segawa Etsuo , Shikano Yutaka
Published: March 2021

We consider crossovers with respect to the weak convergence theorems from a discrete-time quantum walk (DTQW). We show that a continuous-time quantum walk (CTQW) and discrete- and continuous-time random walks can be expressed as DTQWs in some limits. At first we generalize our previous study [Phys. Rev. A \textbf{81}, 062129 (2010)] on the DTQW with position measurements. We show that the position measurements per each step with probability $p \sim 1/n^\beta$ can be evaluated, where $n$ is the final time and $0<\beta<1$. We also give a corresponding continuous-time case. As a consequence, crossovers from the diffusive spreading (random walk) to the ballistic spreading (quantum walk) can be seen as the parameter $\beta$ shifts from 0 to 1 in both discrete- and continuous-time cases of the weak convergence theorems. Secondly, we introduce a new class of the DTQW, in which the absolute value of the diagonal parts of the quantum coin is proportional to a power of the inverse of the final time $n$. This is called a final-time-dependent DTQW (FTD-DTQW). The CTQW is obtained in a limit of the FTD-DTQW. We also obtain the weak convergence theorem for the FTD-DTQW which shows a variety of spreading properties. Finally, we consider the FTD-DTQW with periodic position measurements. This weak convergence theorem gives a phase diagram which maps sufficiently long-time behaviors of the discrete- and continuous-time quantum and random walks.
Practical four-dimensional quantum key distribution without entanglement
Authors: Buttler William T. , Lamoreaux Steven K. , Torgerson Justin R.
Published: March 2021

We describe a four-dimensional ($\mathcal{D} = 4$) single-photon quantum cryptography protocol with up to twenty ($\mathcal{D} \times (2^2 + 1)$) possible states generated by a polarization-, phase- and time-encoding transmitter. This protocol can be experimentally realized with existing technology, drawing from time- and polarization-encoded systems. The protocol is error tolerant and has a maximum raw bit rate of two raw bits per detection, which when combined with state detection efficiency yields a qubit rate of up to one per transmission under ideal assumptions, or up to twice the raw bit rate of two-dimensional protocols such as the well-known BB84 protocol.
Bell violations through independent bases games
Authors: Regev Oded
Published: March 2021

In a recent paper, Junge and Palazuelos presented two two-player games exhibiting interesting properties. In their first game, entangled players can perform notably better than classical players. The quantitative gap between the two cases is remarkably large, especially as a function of the number of inputs to the players. In their second game, entangled players can perform notably better than players that are restricted to using a maximally entangled state (of arbitrary dimension). This was the first game exhibiting such a behavior. The analysis of both games is heavily based on non-trivial results from Banach space theory and operator space theory. Here we provide alternative proofs of these two results. Our proofs are arguably simpler, use elementary probabilistic techniques and standard quantum information arguments, and also give better quantitative bounds.
Classical simulation of dissipative fermionic linear optics
Authors: Bravyi Sergey , Konig Robert
Published: March 2021

Fermionic linear optics is a limited form of quantum computation which is known to be efficiently simulable on a classical computer. We revisit and extend this result by enlarging the set of available computational gates: in addition to unitaries and measurements, we allow dissipative evolution governed by a Markovian master equation with linear Lindblad operators. We show that this more general form of fermionic computation is also simulable efficiently by classical means. Given a system of $N$~fermionic modes, our algorithm simulates any such gate in time $O(N^3)$ while a single-mode measurement is simulated in time $O(N^2)$. The steady state of the Lindblad equation can be computed in time $O(N^3)$.
Poly(catecholamine) coated CsPbBr3 perovskite microlasers: lasing in water and biofunctionalization
Authors: Cho Sangyeon , Yun Seok-Hyun
Published: March 2021

Lead halide perovskites (LHP) microcrystals are promising materials for various optoelectronic applications. Surface coating on particles is a common strategy to improve their functionality and environmental stability, but LHP is not amenable to most coating chemistries because of its intrinsic weakness against polar solvents. Here, we describe a novel method of synthesizing LHP microcrystals in a super-saturated polar solvent using sonochemistry and applying various functional coatings on individual microcrystals in situ. We synthesize cesium lead bromine perovskite (CsPbBr3) microparticles capped with organic poly-norepinephrine (pNE) layers. The catechol group of pNE coordinates to bromine-deficient lead atoms, forming a defect-passivating and diffusion-blocking shell. The pNE layer enhances the stability of CsPbBr3 in water by 2,000-folds, enabling bright luminescence and lasing from single microcrystals in water. Furthermore, the pNE shell permits biofunctionalization with proteins, small molecules, and lipid bilayers. Luminescence from CsPbBr3 microcrystals is sustained in water over 1 hour and observed in live cells. The functionalization method may enable new applications of LHP particles in water-rich environments.

Published: March 2021

The development of adsorbents into structured and robust forms remains a challenge for emerging porous materials. In the context of porous boron nitride (BN), studies point to a tradeoff between mechanical stability, porosity, density, and adsorption kinetics. Approaches towards shaping and densification of porous BN have been mostly empirical since a detailed understanding of its formation mechanism, and how it impacts mechanical strength and porosity, is lacking. Here, we demonstrate a synthesis method that can directly produce a mechanically robust monolithic porous BN (mpBN) from an easily scalable polymeric precursor, which results in the highest volumetric surface area among porous BN samples to date. mpBN exhibits a high bulk density, 50% higher than BN powders and over ten times higher than the structured BN aerogels, while maintaining fast sorption kinetics. mpBN presents good mechanical strength, with hardness of 66.4 ± 4.5 MPa, i.e. one to two orders of magnitude higher than structured aerogels. We propose a mpBN formation mechanism which reveals that the crosslinked intermediates are responsible for the high mechanical strength of the final material. Our approach produces a form of BN that addresses the limitations of other adsorbents, and facilitate their application in gas separation and storage technologies.

We present open-source implementations of the linear-scaling Fast Multipole Method (FMM) within the Polarizable Embedding (PE) model for efficient treatment of large polarizable environments in computational spectroscopy simulations. The implementations are tested for accuracy, efficiency, and usability on model systems as well as more realistic biomolecular systems. We explain how FMM parameters affect the calculation of molecular properties and show that PE calculations employing FMM can be carried out in a black-box manner. The efficiency of the linear-scaling approach is demonstrated by simulating the UV/Vis spectrum of a chromophore in an environment of more than one million polarizable sites. Our implementations are interfaced to several open-source quantum chemistry programs, making computational spectroscopysimulations within the PE model and FMM available to a large variety of methods and a broad user base.

We report here the synthesis of peptidonucleosides obtained after glycosylation of different pyrimidine bases with glucopyranosyl donors carrying an azide group at the C4 position. A methodological study involving different anomeric leaving groups (acetate, phenylsulfoxide and ortho-hexynylbenzoate) showed that a sulfoxide donor in combination with trimethylsilyl triflate as the promoter led to the best yields.
Liquid Graphene Oxide Binder and Modified Glass Fiber Separator for Lithium Sulfur Battery with Highly Improved Cycling Performance
Authors: Kiai Maryam Sadat
Published: March 2021

Lithium sulfur (Li-S) batteries with high theoretical energy density (~2.5 kWh kg-1) and high theoretical gravimetric capacity (1672 mAh g-1) have drawn great attention as they are promising candidates for large scale energy storage devices. Unfortunately some technical obstacles hinder the practical application of Li-S batteries such as formation of polysulfide intermediates between cathode and anode as well as the insulating nature of sulfur cathode and other discharge products. Glass fiber separators provide some cavities to withstand the volume change of sulfur during cycling leading to long-term cycling stability. Here, application of polar materials with novel liquid graphene oxide (L-GO) binder rather than the standard polyvinylidene fluoride (PVDF) binder as effective coatings on the glass fiber separator of the Li-S cell have been developed to suppress the shuttle effect. The deposition of silicon dioxide (SiO2), titanium dioxide (TiO2) and poly (1,5-diaminoanthraquinone) (PDAAQ) with L-GO binder on the glass fiber separator was investigated with polycarboxylate functionalized graphene (PC-FGF/S) cathode and Li metal anode. The cells with modified coatings and L-GO as an efficient binder could accelerate conversion of long-chain polysulfides to short-chain polysulfides and significantly delayed the growth of lithium dendrites resulted the capacity retention of ~ 1020, 1070 and 1190 mAh g-1 for the cells with SiO2/L-GO, TiO2/L-GO and PDAAQ/L-GO coated separators after 100 cycles. The results demonstrate that ultrathin SiO2, TiO2 and PDAAQ containing coatings with L-GO binder on the glass fiber separator can drastically improve the cyclability of the Li-S cells.

Coordination complex and polymer are central in inorganic and material chemistry as a variety of both metal centers and coordination geometries lead to a diverse range of interesting properties. Here, size and structure control of gems-like quality monocrystals are demonstrated at room temperature. From the same set of precursors, but the copper-to-melamine molar ratio is adjusted to synthesize either a novel coordination complex of dinuclear copper and melamine (Cu2M1) or a barely-studied coordination polymer of zigzag copper-chlorine chains (Cu4M1). Crystals of the former are dark green and squared with the size up to 350 µm across. The latter is light green and octagonal as large as 5 mm across. The magnetic properties of both crystals reflect their low-dimensional arrangements of copper. The magnetic susceptibility of Cu2M1 is well modelled with a spin-1/2 dimer and that of Cu4M1 with a spin-1/2 one-dimensional Ising chain. Controlled synthesis of such quality magnetic crystals is a prerequisite for various magnetic and magneto-optical applications

Published: March 2021

Relevance. Problems of chronic heart failure (HF) after myocardial infarction (MI) prevention of in young and middle-aged men with chronic inflammatory pulmonary diseases (CIPD) remain relevant due to their high prevalence and social significance.
Aim. To evaluate changes in the quality of life (QL) indicator associated with heart failure (HF) in men under 60 years old with MI and CIPD to improve prevention and outcomes.
Material and methods. The study included men aged 19-60 years old with type I MI. Patients are divided into two age-comparable groups: I - the study group, with CIPD - 166 patients; II - control, without it - 490 patients. A comparative analysis of the QL indicator associated with HF (HFQL) (V. Ironosov) was performed in the selected groups in the first 48 hours (I) and at the end of the third week (II) of MI. The changes and correlations (C. Spearmen) of HFQL with clinical features, metabolic parameters, central and peripheral hemodynamics were studied.
Results. HFQL in patients with CIPD was worse than in the control group in both phases of the study (I: 63.6 ± 21.6 and 59.2±20.1; II: 20.7 ± 11.7 and 18.0 ± 12.0, respectively; p˂0.05). Reliable correlations between HFQL and heart rate, blood pressure, parameters of the left ventricle (LV) systolic and diastolic functions, its volume, indicators of the pulmonary circulation, lipid, nitrogen and electrolyte metabolism were revealed.
Conclusions. The QL associated with HF is significantly worse in patients with CIPD in the acute and subacute MI periods. The most pronounced negative effect on this indicator in the study group is associated with tachycardia, LV dilatation, its systolic and diastolic dysfunction, pulmonary hypertension, impaired lipid and nitrogen metabolism. The HFQL method is useful as an addition to the complex of examination of patients with MI and MS, starting from the first hours of the disease, for early identification of risk groups for adverse outcomes and the formation of chronic HF.

Relevance. Acute kidneys injury (AKI) negatively affects the prognosis of myocardial infarction (MI). Aim. To evaluate MI clinical features (CF) in men under 60 years old (y.o.) with AKI during MI to improve prevention and outcomes. Material and methods. The study included men aged 19-60 years old with type I MI. Patients are divided into two age-comparable groups: I - the study group, with ACI - 25 patients; II - control, without it - 486 patients. A comparative assessment of the MI CF frequency in selected groups were performed. Results. In patients of the study group more often than in the control group, a combination of MI complications (64.0 and 36.9%; respectively; p = 0.009), psychic disorders (20.0 and 6.9%; p = 0.01), chronic heart failure (CHF) of the second functional class and above (NYHA) at the end of the eighth MI week (72.0 and 43.2%; p = 0.005), with a predominance of newly diagnosed CHF forms (36.0 and 28.0%; p = 0.006). In the study group, less often than in the control group, pulmonary hypertension was noted in the first 48 hours of MI (44.0 and 66.0%; p = 0.02) and at the end of the third MI week (38.1 and 60.3%; p = 0.04). Conclusions. There were no specific clinical signs of AKI in men under 60 y.o. with MI. At the same time, the study group has the worst prognosis during the observation period in terms of the frequency of MI complications combinations and CHF, which requires the start of prophylactic therapy from the moment of AKI verification.

The work is devoted to assessing the effect of thioctic acid on the main laboratory parameters of carbohydrate metabolism (blood glucose, C-peptide and insulin levels, glycated hemoglobin) in diabetes mellitus against the background of glucose-lowering therapy with metformin hydrochloride. The studies were conducted with the participation of 32 volunteers aged 52 to 63 years, 26 of whom type II diabetes mellitus proceeded with III-degree obesity. At the time of the study, all patients were taking metformin hydrochloride (MH) as a hypoglycemic agent. The experiment was carried out for 3 months. All study participants were divided into groups: the first group - the control group, who took only MG 850 mg once a day for; the second group, patients with normal body weight, who took metformin hydrochloride 850 mg and thioctic acid (TA) 600 mg per day; the third group - obese patients receiving the test compound at the same dosage. After 3 months of treatment, all patients underwent biochemical blood tests for the following parameters: blood glucose, glycated hemoglobin, C-peptide and insulin levels. The results obtained indicate that thioctic acid contributed to a more pronounced decrease in carbohydrate metabolism in comparison with the group of patients receiving only MH as a hypoglycemic agent. It was noted that the normalization of the studied parameters was expressed in the group of patients with normal body weight. Thus, the additional introduction of thioctic acid into the treatment regimen for patients with type II diabetes mellitus contributes to a more effective decrease in carbohydrate metabolism and compensation of the disease in comparison with standard therapy.

Discoloration of teeth is an urgent problem of modern dentistry. This is a very common and multifactorial pathology in nature. With this problem, patients turn to dentists of various profiles. This work analyzes the frequency of using various methods for eliminating discoloration of teeth. A survey of 50 doctors of various specializations was conducted and it was found that for the period from September to November 2020, clinical enamel whitening was carried out in 22,5% of patients with tooth discoloration, intracoronal bleaching followed by direct restoration (replacement of existing fillings with new ones) in 30%, covering the vestibular surface of the teeth located in the smile line with ceramic veneers in 22,5% and total prosthetics in 25%. The analysis showed that at present the arsenal of a dentist is quite wide and, depending on the clinical situation taking into account the wishes of the patient and his capabilities, the doctor can choose a way to eliminate the discoloration of the teeth suitable for a particular patient. In addition, the use of this problem is higher among general dentists – 9,4%, in second place in terms of accessibility are dentists orthopedists - 8%, and in third place are dentists therapists – 6,5%. The problem of teeth discoloration, especially accompanied by increased sensitivity, does not lose its relevance in modern dentistry. It seems necessary to develop, test and implement means and methods for quickly and gently eliminating discoloration of teeth, which will not only correct, change the color of the tooth, but also solve the problem of increased sensitivity of teeth.

Abstract. The paper shows the need to study the motivation of migration behavior of citizens from the position of socio-psychological approach, which allows to identify socio-psychological factors that influence the decision-making process of citizens to emigrate from the country, the choice of the preferred country for residence, as well as the refusal to travel abroad. It is shown that the motives and motivational attitudes of migration behavior are associated at the initial stage of migration behavior with the functions of migration. The article presents the classification of migration behavior motives and their description. It is shown that the motives, reflecting the readiness to emigrate from Russia or to remain in the country, caused, on the one hand, socio-psychological characteristics of the individual (social maturity, self-esteem, confidence, social anxiety, features of identity, etc.), reflecting the socio-demographic characteristics of citizens (age, gender, social class, marital status, level of education), and, on the other hand, external factors of migration behavior (the geopolitical situation, the political system, the level of economic development of the country being abandoned and preferred, etc.).

Published: March 2021

this article examines the issue of gender socialization and identity in modern Russian society, on the basis of analysis of gender characteristics of the personality is compared changes in the structure of the psychological sex (gender) in three age groups (up to 20 years - generation y, 20-40 years - Generation Y and 40-60 years - Generation X), analyzes the causes and possible consequences of changes in gender patterns in different generations. Specifically, the study found that changes in the composition of gender properties and a shift away about traditional stereotypes of feminity and masculinity in the direction of mixing gender roles and qualities occurred in all generations, but the most significant transformations occurred in young men and women of the younger age group (generation) and in middle-aged women (generation Y). The article also presents new data on structural changes in the composition of nuclear personality properties of gender: all males with a general tendency to mix gender qualities in the structure of "real self", the nuclear component of gender consists mainly of their masculine qualities, which is especially evident in men of the middle age group (Generation Y). In women of all generations, the nuclear composition of gender's personality were inconsistent and contradictory, and the choice of masculine qualities in the first places of the gender hierarchy in middle- and older age groups (generation Y and X) may indicate a trend towards further transformation of traditional feminist gender.
