The relationship of personality determinants of children with coping strategies in difficult situations
Authors: Aparchina Tatyana , Kiseleva Tatyana , Talanov Sergey , Berezin Dmitry
Published: November 2019

The article presents the results of a comparative analysis of the personal characteristics of children who find themselves in a difficult life situation. The subject of the study was the coping strategies for behavior in stressful situations. The authors used the method of diagnosis of coping mechanisms of E. Heim and Lazarus coping test. The testee’s dominant strategy was confrontation, which exacerbates social deviations and affects the formation of the personality of a child. Features of the formation of the personality of such children is an increased level of psychoticism and neuroticism. Emotional instability and imbalance of children makes it complicated to form constructive communication skills, and leads to social isolation. The latter, in turn, becomes the trigger for the formation of secondary social disorders. Dominant selfish and egocentric manifestations strengthen the increased level of conflict, not contributing to the formation of skills for constructive solutions to difficulties. Material support from the state do not solve, but exacerbate the situation, provoking the formation of a consumer position. The authors of the article believe that changing the situation requires comprehensive psychological and pedagogical support and follow up throughout childhood, not only for the child, but also his family.

The purpose of the study presented in the article is an empirical study of typical dynamic peculiarities spheres of young people’ social activity manifestation. The study sample consisted of 240 participants (Saratov region, Russia), including: university students (n = 120), age M = 18.22 (SD = 0.87) and high school students (n = 120), age M = 16.43; SD = 0.53. We used a questionnaire (R. M. Shamionov, I. V. Arendachiuk, E. E. Bocharova et al.) to register various forms of social activity and the degree of their manifestation, and the “Morphological Test of Life Values” technique (V. F. Sopov, L. V. Karpushina) to study various spheres of life. In the sample of students we have recorded a trend towards negative dynamics in the range of typical spheres of social activity manifestation, which, moreover, differs in its substantive multidirectionality. The study has shown that manifestation of various forms of social activity in the typical spheres of life is characterized by multidirectional dynamics of their motives’ actualization, depending on the person’s social and age-related status. The applied aspect of the problem under study can be implemented in the development of youth policy programs.
Features of students ’ vision of teachers
Authors: Chomaeva Gokkajan , Kubanova Marina
Published: November 2019

The article is devoted to the analysis of an important aspect of pedagogical interaction between teachers and students as the idea/vision of each other, in particular the image of the teacher through the eyes of the student. The vision of a communication partner is the basis for the formation of an attitude towards him and the activities performed by him. A positive attitude to the teacher motivates cognitive activity of students, stimulates interest in the future profession, i.e. is a factor of productive interaction in the educational process. The study is based on the use of projective techniques, which revealed the differences in students ’ ideas about the ideal and the real teacher. Assessing the overall results of the study, we can say that there is a clear difference in the assessments of teachers in comparison with the student’s ideas about the ideal teachers. Students negatively characterize the real pedagogical interaction and want more softness, joy, positive emotions from interesting teachers. Taking into account the data obtained will help to improve the efficiency of the pedagogical process.

Authors: Chorniy Yevgeniy , Galchenko Ann
Published: November 2019

The article presents the theoretical model of the study of civil identity. The model of the civil identity research is presented as the ratio of two indicators: the status of civil identity and the content of its structural components (cognitive, emotional-evaluative, need-motivational). At the cognitive component level the psychological determinant of the civil identity formation is determined as the ability to conceptualization in the field of civil problems; at the emotional-evaluative level – the combination features of positive / negative civil identity valence and the personality reflexivity level; at the emotional-evaluative component level – the nature structural organization of the adolescents’ civic activity motivation. As the result of the empirical research it is revealed that the process of the status of civil identity formation is due to the selected psychological determinants and is characterized by the following regularities: the transition from lower statuses (diffuse and predefined) to higher (moratorium and reached) is accompanied by the progressive change of the development of the ability to conceptualize, the changes in the motives of the structural connections content and the young people’s civil activity motivation structure differentiation, and the differences in the priority type of emotionalevaluative attitude to civic identity.

Published: November 2019

Bullying is a dangerous phenomenon that affects many modern students around the world. Bullying destructively affects a person regardless of the role (aggressor, observer, victim) and, despite measures to overcome, is present at school. Bullying (from the point of view of the contextual approach) is a social-group phenomenon that accompanies the development of a group with an unconstructive deformation of relationships in it. We conducted a research that reveals how Russian students are prone to bullying, how (taking into account gender and experience of it) are aware of its causes, who can stop bullying and whom they are ready to turn for help to if they become observers or victims of bullying. The results of the study showed that 46.8% of students felt oppressed during the school year (2018-2019). Students realize that the school class can stop bullying, but in a bullying situation they turn to parents, teachers, less to friends, do not mention the school class.

Authors: Ryumshina Liubov
Published: November 2019

Professional identity is the embodiment of life’s meanings and values of the individual. Its fulfillment rests in its basis on the person’s perception of oneself and attitude toward oneself. Even choosing a certain profession and studying it, the students still have a choice of further professional identity. In consideration of the foregoing,the purpose of the work is to study the characteristics of self-perception and meaningful orientations of professionally determined students. Methodological tools of the study were Maslow’s self-actualization scales, a test of meaningful orientations, a questionnaire aimed at identifying professionally determined and not determined students. 96 students took part in the study. The results showed that professionally determined students have a tendency to a fairly high general meaningfulness of life. They feel that they can manage their own lives and have a sufficient level of responsibility. The self-esteem of the professionally determined students is related to the positive perception of their life in each of its periods. In general, professionally determined students have many characteristics similar to professionally not determined students, but they also have specific features. They are manifested in the interconnection between meaningful orientations, self-esteem and self-acceptance of professionally determined and not determined students.

Authors: Pratsko Gennady , Petrasheva Natalia , Romanova Lyudmila , Ryabko Natalia
Published: November 2019

The basis of interpersonal relationships is communication as a means of information exchange and an important factor in influence on the of personality`s development. There is a world perception, norms awareness and society values which are perceived through the prism of interpersonal relations. The young people are characterized by the lack of accumulated life experience; values are influenced from the outside, so that influence is the reason for their unstable behavior in the legal field. In a transitive society, all processes are exacerbated, including growing deviant behavior of adolescents. Qualitative work in the organization of legal support of interpersonal relations in the educational environment can help to keep students from committing negative manifestations in interpersonal communication. This form of activity of the teaching staff could be an integral part of the preventive impact on students.

Cerebral Hyperperfusion Syndrome after Carotid Revascularization: A Brief Review
Authors: Anand Saurabh , Sahoo Asish K.
Published: November 2019

Cerebral hyperperfusion (CHS) syndrome is a relatively rare but potentially devastating event that can complicate carotid endarterectomy and carotid stenting. It is associated with increased cerebral perfusion usually more than 100% from the baseline along with ipsilateral headache, seizures, focal neurological deficits, encephalopathy, intracranial hemorrhage, or subarachnoid hemorrhage. Various risk factors have been identified but most important risk factor is preprocedure evidence of reduced cerebral vasoreactivity with or without contralateral severe carotid stenosis or occlusion. Although diagnosis is suspected in patients with clinical suspicion, it can be radiologically demonstrated with computed tomography (CT), magnetic resonance imaging (MRI), and by dynamic imaging of cerebral perfusion such as transcranial Doppler (TCD), CT, and MR perfusion, and single-photon emission computed tomography (SPECT). Management is usually centered around prompt recognition and active regulation of blood pressure in perioperative and postoperative periods to limit the rise of cerebral blood flow. Prognosis depends on the early detection and prompt management of CHS. If detected early, coupled with intensive blood pressure management, almost all patients will recover over a period of time. For those patients who are diagnosed late and those progressing to intracranial hemorrhage (ICH), the prognosis is not nearly as good.

Published: November 2019

Variations in the renal vasculature always deserve a special attention owing to its higher prevalence and wider range. A thorough knowledge of the normal morphology and the variations in the origin, course, branches and distribution of the renal vasculature are essential for the successful outcome of the surgical interventions in this region without dreadful complications. During routine dissection for the undergraduate medical students following the standard procedures, dissection of the retroperitoneal region in a male cadaver, revealed bilateral variations in the number, origin, course and branches of the renal arteries.The renal arteries with its branches were dissected out meticulously and the variations encountered were documented. Bilateral supernumerary renal arteries with extra-hilar and pre-hilar branches were observed. In addition, it was found that the supernumerary inferior pre- caval right renal artery had a variant course in relation to ureter before entering the hilum of the right kidney. The variant renal arteries documented in the present study with their embryological correlation is clinically important in the urological management, especially during the laparoscopic donor nephrectomy, where the field of vision is limited and also in the endovascular renal artery denervation procedure, which is an useful adjuvant for the patients having drug-resistant primary hypertension.

Objective There is increasing interest in investigating the utility of 7 Tesla (7 T) magnetic resonance imaging (MRI) for imaging of skull base tumors. The present study quantifies visualization of tumor features and adjacent skull base anatomy in a homogenous cohort of pituitary adenoma patients.

Methods Eighteen pituitary adenoma patients were scanned at 7 T in this prospective study. All patients had reference standard-of-care clinical imaging at either 3 T (7/18, 39%) or 1.5 T (11/18, 61%). Visualization of tumor features and conspicuity of arteries and cranial nerves (CNs) was rated by an expert neuroradiologist on 7 T and clinical field strength MRI. Overall image quality and severity of image artifacts were also characterized and compared.

Results Ability to visualize tumor features did not differ between 7 T and lower field MRI. Cranial nerves III, IV, and VI were better detected at 7 T compared with clinical field strength scans. Cranial nerves III, IV, and VI were also better detected at 7 T compared with only 1.5 T, and CN III was better visualized at 7 T compared with 3 T MRI. The ophthalmic arteries and posterior communicating arteries (PCOM) were better detected at 7 T compared with clinical field strength imaging. The 7 T also provided better visualization of the ophthalmic arteries compared with 1.5 T scans.

Conclusion This study demonstrates that 7 T MRI is feasible at the skull base and identifies various CNs and branches of the internal carotid artery that were better visualized at 7 T. The 7 T MRI may offer important preoperative information that can help to guide resection of pituitary adenoma and reduce operative morbidity.
Effect of doping mechanism on photogenerated carriers behavior in Cu-doped ZnSe/ZnS/L-Cys core-shell quantum dots
Authors: Li K. Y. , Yang L. S. , Cui J. Y. , Li S. , Li G.
Published: November 2019

Cu-doped ZnSe/ZnS/L-Cys core–shell QDs are prepared by both nucleation doping and growth doping in an aqueous synthesis method. Transport of photogenerated free charge carriers (FCCs) in these Cu-doped QDs is probed via a combination of surface photovoltaic (SPV), photoacoustic (PA), and electric-field-induced SPV techniques, supplemented by the UV–VIS absorption spectrum and Raman spectrum. The results confirm that the two doping mechanisms result in different doping locations and microelectronic structures of the Cu-doped QDs. The distinctive microelectronic structure of the QDs prepared by nucleation doping, as compared with those prepared by growth doping, results in a number of favorable SPV characteristics. For example, the QDs prepared by nucleation doping exhibit a higher SPV response intensity at 600 nm because of a higher concentration of photogenerated FCCs. The ratio of the strongest SPV response and the strongest PA signal of the QDs prepared by nucleation doping is up to 2.41 times greater than those of the QDs prepared by growth doping. This is because the greater numbers of photogenerated FCCs in the QDs prepared by nucleation doping generate the PV effect rather than the PA effect that is caused by a nonradiative de-excitation process. The position of the shoulder peak of the SPV response at a long wavelength of the QDs prepared by nucleation doping is significantly red-shifted compared with that of the QDs prepared by growth doping, leading to a broader SPV response range in the visible region. The QDs prepared by nucleation doping have a more obvious donor feature than those prepared by growth doping.
Modulation of terahertz electromagnetically induced absorption analogue in a hybrid metamaterial/graphene structure
Authors: Xiong Wen , Wang Weijun , Ling Furi , Yu Wenfeng , Yao Jianquan
Published: November 2019

We proposed a two-layer metamaterial structure with graphene that consists of two H-shaped resonators and one I-shaped resonator. The electromagnetically induced absorption (EIA) analog phenomena were observed in absorption spectra, resulting from the near-field coupling of two bright modes. Furthermore, the absorption peak can be tuned by changing the dimension of the I-shaped resonator or changing the Fermi energy of graphene. The theoretical analysis reveals that the EIA analog arises from magnetic resonance using the coupled Lorentz oscillator model. This hybrid-EIA analog structure may provide a possible choice for designing potential devices for dynamic narrow-band filtering and absorber applications.
The numerical oscillation suppression method for the large time step scheme
Authors: Wang Dong-Xu , Hu Qi-Hui , Li Yu-Xing , Li Shuang
Published: November 2019

The large time step scheme, which is commonly used in hydrodynamic numerical simulation, adopts the multielement reconstruction method in order to improve both the computational efficiency and accuracy; however, this results in numerical oscillation and calculation divergence. Therefore, it is necessary to develop methods to suppress the occurrence of numerical oscillation near the discontinuities. The numerical oscillation that is induced can be suppressed by using the random choice method (RCM) with the van der Corput random number sequence. In order to optimize the suppression performance, error analysis has been carried out in this paper for the calculation results from the RCM with the popular van der Corput random sequence combinations for selecting the optimal sequence combination. In order to further eliminate any short-wave numerical oscillations near the discontinuities, a method that combines the RCM with a nonlinear filter, which often used in aeroacoustic calculations, has been proposed in this paper to suppress short-wave oscillations. Specifically, the RCM and the nonlinear filter method were sequentially implemented in order to process the calculation results at each time step. The results showed that this method had a good suppression effect on the numerical oscillations near the discontinuities, which was demonstrated by the numerical experiments.

The extension of the roadmap of shorter wavelength extreme ultraviolet and soft x-ray sources is a topic of considerable interest. We have studied the optimized emission from high power and/or high brightness sources based on unresolved transition array (UTA) emission. The peak UTA wavelengths follow a quasi-Moseley’s law as λ=33.82×R∞−1(Z−20.86)−1.61 nm for the laser wavelength of 1064 nm (the critical density of 1 × 1021 cm−3) and λ=165.8×R∞−1(Z−12.44)−1.94 nm for the laser wavelength of 532 nm (the critical density of 4 × 1021 cm−3), respectively. The photon flux decreased with increasing atomic number. We also mapped the optimum electron temperatures and corresponding charge states required to produce strong soft x-ray UTA emission with a photon flux of the order of 1014 photons nm−1 sr−1. The present quasi-Moseley’s law is sufficient for identifying the optimum element for numerous applications, such as material ablation and ionization, nanolithography, and in vivo biological imaging.

Published: November 2019

Kuji amber is fossilized tree resin of the Late Cretaceous in Japan. In this study, new biological activities of ethanol extract of Kuji amber (EtOH ext.) and supercritical carbon dioxide fluid extract of Kuji amber (scCO2 ext.) were examined. Both EtOH ext. and scCO2 ext. inhibited melanin production in B16 mouse melanoma cells and promoted collagen production in human skin fibroblast SF-TY cells. The scCO2 ext. had more potent activity than that of EtOH ext. and may depend on the efficiency of the extraction. The main new biologically active compound in Kuji amber, kujigamberol had no activities against melanin production, however, it promoted collagen production at low concentrations. A biologically active compound having a different structure, spirolactone norditerpenoid, showed both the inhibition activity against melanin production and the promotion activity of collagen production in a dose dependent manner. EtOH ext. and scCO2 ext., which include both kujigamberol and spirolactone norditerpenoid, have not only anti-allergy activity, but also inhibit melanin production and promote collagen production.
One-way steering of the optical fields with respect to the low-Q cavity via the thermal noise
Authors: Zhong Wenxue , Cheng Guangling , Hu Xiangming
Published: November 2019

We show that thermal noise could play a positive role in generating one-way Einstein–Podolsky–Rosen (EPR) steering of two cavity fields dispersively interacting with a single four-level atom, each of which is independently coupled to a thermal reservoir. In the low-Q and weak Raman transition regimes, two output fields exhibit asymmetric EPR steering and the steering direction could be easily controlled by adjusting the mean photon numbers of the thermal reservoirs and the decay rates of cavities. Striking features are present in our scheme. First, one-way EPR steering is achieved by using the couplings of the cavities with the heat baths, which sheds light on the quantum state manipulation in the presence of decoherence. Second, the obtainable EPR steering occurs between the cavity fields in the low-Q regime, which relaxes the constraints on the use of good cavities and so makes our scheme more practical. Third, the correlation properties of the output modes are considered, which can be measured more conveniently and will be more applicable to implement a range of quantum information processing.

< 2.5 MeV (67 energy points), and that for the 10B(n, α
0) 7Li and 10B(n, α
1) 7Li* reactions is 1.0 eV ≤ En
< 1.0 MeV (59 energy points). The present results have been analyzed by the resonance reaction mechanism and the level structure of the 11B compound system, and compared with existing measurements and evaluations.
Possibilities of producing superheavy nuclei in multinucleon transfer reactions based on radioactive targets *
Authors: Zhu Long
Published: November 2019

The multinucleon transfer (MNT) process has been proposed as a promising approach to produce neutron-rich superheavy nuclei (SHN). MNT reactions based on the radioactive targets 249Cf, 254Es, and 257Fm are investigated within the framework of the improved version of a dinuclear system (DNS-sysu) model. The MNT reaction 238U + 238U was studied extensively as a promising candidate for producing SHN. However, based on the calculated cross-sections, it was found that there is little possibility to produce SHN in the reaction 238U + 238U. In turn, the production of SHN in reactions with radioactive targets is likely.
Nuclear mass parabola and its applications *

Published: November 2019

We propose a method for extracting the properties of the isobaric mass parabola based on the total double

-decay energies of isobaric nuclei. Two important parameters of the mass parabola, the location of the most

-stable nuclei

and the curvature parameter

, are obtained for 251 A values, based on the total double

-decay energies of nuclei compiled in the AME2016 database. The advantage of this approach is that the pairing energy term

caused by the odd-even variation can be removed in the process, as well as the mass excess

of the most stable nuclide for the mass number A, which are employed in the mass parabolic fitting method. The Coulomb energy coefficient

MeV is determined by the mass difference relation for mirror nuclei, and the symmetry energy coefficient is also studied by the relation

The structure of neutron-rich calcium isotopes studied by the shell model with realistic effective interactions *

Published: November 2019

We study the structure of neutron-rich calcium isotopes in the shell model with realistic interactions. The CD-Bonn and Kuo-Brown (KB) interactions are used. As these interactions do not include the three-body force, their direct use leads to poor results. We tested whether the adjustment of the single particle energies (SPEs) would be sufficient to include the three-body correlations empirically. It turns out that the CD-Bonn interaction, after the adjustment of SPEs, gives good agreement with the experimental data for the energies and spectroscopy. For the KB interaction, both the SPEs and monopole terms require adjustments. Thus, the monopole problem is less serious for modern realistic interactions which include perturbations up to the third order. We also tested the effect of the non-central force on the shell structure. It is found that the effect of the tensor force in the CD-Bonn interaction is weaker than in the KB interaction.
Is X(3872) a bound state? *
Authors: Ortega Pablo G. , Arriola Enrique Ruiz
Published: November 2019

All existing experimental evidence for the bound state nature of

relies on observing its decay products, which are measured with a finite experimental mass resolution that is typically

MeV , and much larger than its alleged binding energy,

MeV. On the other hand, we have found recently that there is a clear cancellation in the

channel of the invariant

mass around the threshold between continuum and the bound state. This is very much like a similar cancellation in the proton-neutron continuum with the deuteron in the

channel. Based on comparative fits with a common Tsallis distribution of the experimental cross-sections for prompt production of deuterons and

in pp collisions with a finite

, we find a strong argument for questioning the bound state nature of this state, which also suggests that the large observed production rate could be consistent with a half-bound state.

Published: November 2019

A microscopic high spin study of neutron deficient and normally deformed 133,135,137Sm has been carried out in projected shell model framework. The theoretical results have been obtained for the spins, parities and energy values of yrast and excited bands. Besides this, the band spectra, band head energies, moment of inertia and electromagnetic transition strengths are also predicted in these isotopes. The calculations successfully give a deeper understanding of the mechanism of the formation of yrast and excited bands from the single and multi-quasi particle configurations. The results on moment of inertia predict an alignment of a pair of protons in the proton (1h
11/2)2 orbitals in the yrast ground state bands of 133-137Sm due to the crossing of one quasiparticle bands by multi-quasiparticle bands at higher spins. The discussion in the present work is based on the deformed single particle scheme. Any future experimental confirmation or refutation of our predictions will be a valuable information which can help to understand the deformed single particle structure in these odd mass neutron deficient 133-137Sm.

The electric quadrupole moment

and the magnetic moment

(or the

factor) of low-lying states in even-even nuclei 72-80Ge and odd-mass nuclei 75-79Ge are studied in the framework of the nucleon pair approximation (NPA) of the shell model, assuming the monopole and quadrupole pairing plus quadrupole-quadrupole interaction. Our calculations reproduce well the experimental values of

and

for 72,74,76Ge, as well as the yrast energy levels of these isotopes. The structure of the

states and the contributions of the proton and neutron components in

and

are discussed in the

-pair truncated shell-model subspace. The overall trend of

and

as a function of the mass number

, as well as their signs, are found to originate essentially from the proton contribution. The negative value of

in 72,74Ge is suggested to be due to the enhanced quadrupole-quadrupole correlation and configuration mixing.
Weak cosmic censorship conjecture and thermodynamics in quintessence AdS black hole under charged particle absorption *
Authors: He Ke-Jian , Hu Xin-Yun , Zeng Xiao-Xiong
Published: November 2019

Considering the cosmological constant as the pressure, this study addresses the laws of thermodynamics and weak cosmic censorship conjecture in the Reissner-Nordström-AdS black hole surrounded by quintessence dark energy under charged particle absorption. The first law of thermodynamics is found to be valid as a particle is absorbed by the black hole. The second law, however, is violated for the extremal and near-extremal black holes, because the entropy of these black hole decrease. Moreover, we find that the extremal black hole does not change its configuration in the extended phase space, implying that the weak cosmic censorship conjecture is valid. Remarkably, the near-extremal black hole can be overcharged beyond the extremal condition under charged particle absorption. Hence, the cosmic censorship conjecture could be violated for the near-extremal black hole in the extended phase space. For comparison, we also discuss the first law, second law, and the weak cosmic censorship conjecture in normal phase space, and find that all of them are valid in this case.

Hyperglycemia is a condition in which the blood glucose level exceeds reasonable limits. Hyperglycemia is a clinical manifestation of diabetes disorder, a metabolic disorder characterized by resistance to insulin action, inadequate insulin secretion or both. Research has been conducted to determine the blood sugar level of male mice after given the biscuit from Kepok banana skin (Musa paradisiaca L.). The experiment was conducted experimentally with completely randomized design (CRD) design with five treatments, i.e., positive and negative control, the concentration of banana skin flour, i.e., 25%, 50%, and 75%. Each treatment was repeated as many as six tests. Before treatment, the mice were induced with alloxan to create hyperglycemia conditions. The biscuit from banana skins was given for 14 days. The results of research that has been done show that the administration of biscuit from Kepok banana skin could reduce blood sugar levels of mice who have hyperglycemia. Also, after given the biscuit from Kepok banana skin does not affect body weight of hyperglycemic mice. The biscuit from Kepok banana skin on levels 75% can be consumed for people with hyperglycemia to lower blood sugar.

Published: November 2019

Physalis angulata has identified by molecular phylogenetic analysis and the results showed genetically close related with an anticancer plant, Withania somnifera. The aims of this preliminary study was to evaluate cytotoxicity effects of leaf extract of P. angulata (LEP) either in powder or pasta form on cells viability, cells proliferation, and inhibition on human ovary cancer cell lines (SKOV3) and human blood cancer cell lines (HL60). Cytotoxicity effects was analysed by MTS Cell Proliferation Assay Kit. Doxorubicin was used as positive control in this experiment. Surprisingly, two treatments (powder and pasta) have different toxic effects. We found that IC50 and viability (LC50) for SKOV3 cell lines for powder was between 93 ug/ml and 187 ug/ml, and 187 ug/ml and 375 ug/ml for pasta. IC50 for HL60 cell lines was 23 ug/ml for powder and around 18 ug/ml for pasta. Cell viability (LC50) of HL60 treated with LEP showed that 23 ug/ml for powder or 46 ug/ml for pasta. These results suggested that LEP have antiproliferative and inhibition activities both on SKOV3 or HL60.
