Detection of oil–water interface based on laser-induced breakdown spectroscopy
Authors: Fu Xingqiao , Men Jinliang , Zhou Kainan , Feng Guoying , Han Jinghua , Xie Na
Published: February 2021

Oil leakages can result in significant environmental pollution, and effective methods for separating oil and water must be developed. During this process, being able to accurately determine the interface between oil and water is particularly important. In this study, laser-induced breakdown spectroscopy (LIBS) was used to detect the luminescence spectra of oil and water with the aim of accurately determining the oil–water interface. The underlying principle exploited in this work is that the constituent elements of oil and water are different and hence will exhibit different characteristic peaks. Thus, based on these peaks, the position of the interface can be determined. More specifically, one can determine whether the oil and water have been separated completely based on the presence (or absence) of the characteristic peak of the elemental C in the oil. In addition, based on the ratio of the intensities of the C and H peaks in the LIBS spectrum, the thickness of the oil layer below the breakdown depth can be determined. What’s more, it is considerable to detect the thickness of the upper-layer liquid between two organic liquids or one with water which are immiscible in breaker, through the same way as analysing the effects of the oil–water interface spectroscopy detection.

Reservoir-engineered entanglement in an unresolved-sideband optomechanical system
Authors: Wang Yang-Yang , Zhang Rong , Chesi Stefano , Wang Ying-Dan
Published: February 2021

We study theoretically the generation of strong entanglement of two mechanical oscillators in an unresolved-sideband optomechanical cavity, using a reservoir engineering approach. In our proposal, the effect of unwanted counter-rotating terms is suppressed via destructive quantum interference by the optical field of two auxiliary cavities. For arbitrary values of the optomechanical interaction, the entanglement is obtained numerically. In the weak-coupling regime, we derive an analytical expression for the entanglement of the two mechanical oscillators based on an effective master equation, and obtain the optimal parameters to achieve strong entanglement. Our analytical results are in accord with numerical simulations.

Published: February 2021

Bulk anisotropic Sm2Co7 nanocrystalline magnets were successfully prepared by hot deformation process using spark plasma sintering technology. The coercivity of the isotropic Sm2Co7 nanocrystalline magnet is 34.76 kOe, further, the ultra-high coercivity of 50.68 kOe is obtained in the anisotropic hot deformed Sm2Co7 magnet when the height reduction is 70%, which is much higher than those of the ordinarily produced hot deformed Sm2Co7 magnet. X-ray diffraction (XRD) analysis shows that all the samples are Sm2Co7 single phase. The investigation by electron backscatter diffraction indicates that increasing the amount of deformation is beneficial to the improvement of the (00l) texture of Sm2Co7 magnets. The Sm2Co7 nanocrystalline magnet generates a strong c-axis crystallographic texture during large deformation process.

Localization transition in the discrete nonlinear Schrödinger equation: ensembles inequivalence and negative temperatures
Authors: Gradenigo Giacomo , Iubini Stefano , Livi Roberto , Majumdar Satya N
Published: February 2021

We present a detailed account of a first-order localization transition in the discrete nonlinear Schrödinger equation, where the localized phase is associated to the high energy region in parameter space. We show that, due to ensemble inequivalence, this phase is thermodynamically stable only in the microcanonical ensemble. In particular, we obtain an explicit expression of the microcanonical entropy close to the transition line, located at infinite temperature. This task is accomplished making use of large-deviation techniques, that allow us to compute, in the limit of large system size, also the subleading corrections to the microcanonical entropy. These subleading terms are crucial ingredients to account for the first-order mechanism of the transition, to compute its order parameter and to predict the existence of negative temperatures in the localized phase. All of these features can be viewed as signatures of a thermodynamic phase where the translational symmetry is broken spontaneously due to a condensation mechanism yielding energy fluctuations far away from equipartition: actually they prefer to participate in the formation of nonlinear localized excitations (breathers), typically containing a macroscopic fraction of the total energy.

Authors: Nesterchuk O A , Grishin O E , Chepurnaya A M
Published: February 2021

The research emphasis of the article is focused on the urgent problem of digitalization of education. Depending on the degree of development of states, the digitalization of education is uneven. In the context of the COVID 19 pandemic, digitalization has accelerated, consolidated and approved the distance learning system, while revealing a number of problems: insufficient technology, lack of appropriate software, unprofessional teaching staff, unwillingness of students to study using distance learning technologies, etc. The article highlights the main barriers to the development and promotion of digitalization of the Russian educational environment in the "new reality". The dependence of the digitalization of the Russian educational environment on internal and external factors determining the competitiveness of universities in providing their services in a digital format is determined. Analysis of the work of higher school teachers during the period of distance learning revealed some patterns. Teachers used traditional forms of work even when switching to a distance format; a significant part of communications with students was carried out through e-mail and popular training sites. Sometimes work with students was limited to issuing a mandatory task, which must be solved on the proposed portals. Some large higher educational institutions have their own specialized corporate portals through which work with students is carried out: lectures, webinars, tests and tests are held. Attention is focused on the gamification of educational activities as an effective teaching tool. A low degree of student involvement in the educational process, weak motivation and the inability to organize effective control of students’ knowledge are stated. To enhance the effect of digitalization in education, the above barriers should be removed.

It is very important for a specialist to be able to make a deliberate, balanced choice when making a decision, not to succumb to momentary emotions. The ability to recognize and manage one’s own emotions is an important professional quality, on which professional efficiency depends; these are all components of emotional intelligence. Using N. Hall’s method of diagnosing emotional intelligence, we analyzed emotional intelligence of Western branch of The Russian Presidential Academy of National Economy and Public Administration students according to five main indicators: Emotional Awareness, Managing Emotions, Self-Motivation, Empathy, Managing of other people’s emotions. We conducted a variable-based analysis of the obtained indicators characterizing the components of emotional intelligence. As a result of the study, we found that the indicators "Managing emotions" and "Emotional awareness" are close to an inverse linear relationship–and their distribution does not obey the laws of normal distribution of a random value. We found that the distribution according to the scales "Emotional awareness" and "Managing Emotions" has significant left-sided asymmetry, i.e. demonstrate values below expected. In order to improve the training of students, we designed the content part of a new educational technology–"Emotional literacy development" course to form important professional qualities of specialists and contribute to ensuring global security.

This article explores a number of problems of implementing Smart-education for training of students of correspondence department. Its effectiveness for the system of modern higher education is shown. A number of problems of introducing Smart-education for teaching extramural students have been investigated. Its effectiveness for the modern education system is shown. However, the use of Smart-technologies in itself does not allow raising the level of education; it can only be used as a lever that will simplify and speed up the process of communication between the participants in the learning process. E-learning does not allow, in general, to solve the problem of adapting the educational process to the requirements that employers impose on graduates of higher educational institutions, but at the same time it allows the training to be optimized and brought to a higher level. Smart-technologies, in our opinion, are a promising modern technology that penetrates deeply into various types of human activity, and into education. The main distinguishing feature of smart technologies is the ability to quickly adapt quickly to changes in the external environment.

Published: February 2021

The modern education system today is represented by a variety of various educational technologies existing and used in the practice of educational institutions. The system of higher education in this case is no exception, since it is in the practice of universities responsible for the training of future specialists that we can observe the variety of available educational technologies. The use of innovative technologies in the educational process is justified, because the modern federal state educational standard, which regulates the training of highly qualified personnel, makes certain requirements for the training of specialists. This means that these requirements primarily relate to the quality and content of education. In this case, the quality of education can be ensured if the education system is rebuilt in accordance with the new trends in state policy and the modern order of society. Thus, in accordance with the new requirements, the modernization of education took place, as a result of which the competence-based approach replaced the knowledge one. In this connection, the changes affected, first of all, the content of education and the methods and technologies of teaching used in the educational process.

Published: February 2021

Improving the quality of rolled steel products is the primary task of the entire steel industry. As the main step of rolled steel production, hot rolling has received extensive attention. As far as the hot rolling process is concerned, the chemical composition of steel and related process parameters are the most direct factors affecting the quality of hot rolled steel sheets. Based on Principal Component Analysis (PCA) and Gradient Lifting Decision Tree (GBDT) methods, this paper takes the tensile strength as the research object and constructs a prediction model for the mechanical properties of hot rolled strip steel. Through principal component analysis of characteristic data, 28 variables were reduced into 8 new indicators to be used for GBDT regression analysis. 2489 pieces of data were divided into a training set and a test set at a ratio of 7:3, to be used in the training set to build a regression model, and get a root mean square error of 16.7393. The data in the test set was used to predict the tensile strength value, with the root mean square error reaching 18.2650.

Authors: Huang Qiaolong , Chen Qin
Published: February 2021

This paper explored the difference of health damage caused by PM2.5 among the rural mid-aged and elderly in the same pollution level areas. In addition, the reason for the difference is also discussed. The results indicate that one unit concentration increase in PM2.5 is related to a statistically significant 1.82% increase in the probability of suffering chronic cardio-cerebrovascular diseases, respiratory diseases for the low-income individuals. It is 0.0012 higher than those with high income. In addition, the mid-aged and elderly in the areas with high per capita GDP face a higher risk of having the related chronic diseases. Personal health awareness and local medical service infrastructure play positive roles in reducing the health impacts of PM2.5.
