Analysis of cerium oxide by arc atomic emission spectrometry
Authors: Arkhipenko A. A. , Koshel E. S. , Baranovskaya V. B.
Published: November 2021

Materials based on rare earth elements (REE) are of great importance due to their unique chemical and physical properties, but the effectiveness of their use depends on the quality of raw materials. Therefore, further development of the methods of analytical control in relation to rare-earth materials is aimed at increasing the accuracy and sensitivity of the methods, as well as at expanding the nomenclature and concentration range of the determined elements. Cerium oxide is used in glasses, ceramics, catalysts, phosphors, composite and scintillation materials, as well as in medicine. The problem of developing a new arc spectral method is extremely urgent to match modern requirements for the accuracy and sensitivity of the impurity determination for monitoring the purity of cerium oxide. A technique for arc atomic emission analysis of cerium oxide which meets modern requirements for the accuracy and sensitivity of the impurity determination has been developed. The range of impurities to be determined is significantly expanded compared to the standardized technique of the 1970s. The goal of this work is to study and develop a modern method for arc optical emission spectral analysis of cerium oxide using the instrumental capabilities of the atomic emission complex «Grand Globula». To specify compromise conditions for the determination of 15 REE impurities and 19 elements more, analytical lines were selected and the dependence of their intensity on the operating mode of the generator, the shape and size of the electrodes, the interelectrode distance, the ratio of the masses of the analyzed sample and graphite powder, as well as on the presence of various carriers (Ga2O3, NaCl, NaF, KCl, S, GeO) was analyzed. Application of the considered methodological approach to the selection of conditions made it possible to develop a method for spectral analysis of cerium oxide without preliminary dissolution of the sample with an extended range of determinable impurities. When studying the curves of the impurity evaporation, an exposure time was chosen to be sufficient for their complete evaporation (100 – 120 sec). The study has shown the 0promising character and feasibility of the developed arc spectral techniques applicable to the analysis of REE-based materials as an alternative to the methods for analysis of solutions. The metrological characteristics of the proposed procedure for the analysis of cerium oxide were evaluated in comparison with the standardized technique.
Mathematical methods for studying risks (resumptive article)
Authors: Orlov A. I.
Published: November 2021

We define risk as an unwanted opportunity and divide risk theory into three stages — risk analysis, risk estimation, risk management. Safety and risk are directly related to each other, being like a «mirror image» of each other which necessitates developing both the general theory of risk and particular theories of risk in specific areas. General risk theory allows for a uniform approach to the analysis, estimation and management of risks in specific situations. Currently, three main approaches to accounting for the uncertainty and describing risks are used — probabilistic and statistical approach, fuzzy sets, and the approach based on interval mathematics. The methods of risk estimation primarily based on probabilistic and statistical models are considered. The mathematical apparatus for estimating and managing risks is based on nonparametric formulations, limit relations, and multi-criteria optimization. Asymptotic nonparametric point estimates and confidence limits for the probability of a risk event are constructed on the base of binomial distribution and the Poisson distribution. Rules for testing statistical hypotheses regarding the equality (or difference) of two probabilities of risk events are proposed. An additive-multiplicative risk estimation model based on a hierarchical risk system based on a three-level risk system has become widespread: private risks — group risks — final risk. For this model, the role of expert estimation is revealed. The prospects of using (in the future) the theory of fuzzy sets are shown. The article deals with the main components of the mathematical apparatus of the theory of risks, in particular, the mathematical support of private theories of risks related to the quality management, innovations and investments. The simplest risk assessment in a probabilistic-statistical model is the product of the probability of a risk event and the mathematical expectation of the accidental damage. Mathematical and instrumental methods for studying global economic and environmental risks are discussed.

Authors: Bishwal Jaya P. N.
Published: November 2021

We study the mixingale estimation function estimator of the drift parameter in the stochastic partial differential equation when the process is observed at the arrival times of a Poisson process. We use a two stage estimation procedure. We first estimate the intensity of the Poisson process. Then we substitute this estimate in the estimation function to estimate the drift parameter. We obtain the strong consistency and the asymptotic normality of the mixingale estimation function estimator.

Aim: Chronic hepatitis C is more severe in elderly patients. In France, Direct Acting Antiviral therapy must be implemented via multidisciplinary team meetings in regional reference centers. This study aimed to define the impact of age on hepatitis C characteristics and medical care types across three groups: <50, 50-70, and >70-yo. Methods: All patients with treated hepatitis C virus mono-infection during 8 to 24 weeks were included. Group comparison was based on 21 hepatitis C characteristic and medical care variables. Results: Male predominance decreased in >50-yo (59.7% vs. 72.5%, p <0.001), disappearing in >70-yo (36.2%, p <0.001). The transmission route varied depending on age, with a sharp fall in drug-use transmission in >50-yo (27.8% vs. 51.9%, p=0.02) and increase in transfusion and nosocomial infection to 30% in >70-yo. Advanced fibrosis increased in >50-yo (57.5% vs. 41.5%, p <0.001), with nearly 2/3 of >70-yo affected. Psychiatric comorbidity incidence was halved in >70-yo (7.1% vs. 14.8%, p <0.01), excessive alcohol consumption was rare (<1%), and smoking significantly dropped with age, as did cannabis consumption (p <0.001). The care structure was not age-dependent, excepting a decreased use of addictology drug prevention and care centers in ≥50-yo. Using therapeutic patient education programs decreased with age (23.8% for >70-yo vs. 43.8% for <50-yo, p <0.01), while drug interaction frequency increased, reaching nearly 25% in >70-yo. Substained virological response 12 rates did not significantly differ across the three groups. Conclusions: Age changes the characteristics and the medical care of hepatitis C, but has no impact on the cure rate.

Internalization of Falsafah “Peri Mestike Gayo” as an Effort To Developing Students’ Characters Based on Local Authority In SMA 1 Takengon Aceh Central District
Authors: Indra Indra , Rasyidin Al , Sukiman Sukiman
Published: November 2021

At present, there are two trending topic studies in the world of education that are hotly discussed, namely character education and local wisdom (indigenization). "Urang Gayo" is one of the ethnic groups in Indonesia that is rich in the noble values of Adat and its culture, until now they are still holding fast to defend it, because they believe that the customs and culture of Gayo can guide them in creating harmonization in the community, forming or fostering character, and does not conflict with the values of Islamic teachings. The internalization of Peri Mestike in education is part of efforts to foster character and as an effort to preserve the values of indigenous wisdom and culture of Gayo. The purpose of this study is to determine the importance of the internalization of the "Peri Mestike" (PM) Gayo philosophy in fostering the character of students, as well as the internalization process. The method used is a qualitative method with the ethnopedagogic approach, the data conclusions using the interview method with the strategy of "Swelling Gengku", (the method of imagery and class). This study shows that education must synergize with local wisdom in fostering the character of students because the culture is their identity. The results showed the importance of PM in internalizing and integrating with education as local wisdom and in schools, as for the process found first; through understanding PM by presenting qualified figures, second; with integration in learning material, third; through extracurricular activities, photos or posters that read PM sentences. Furthermore, the school through the principal's policy will continue to try to formulate with the teachers so that the PM can be a subject of local content.

Authors: Joseph Joseph Ugochukwu
Published: November 2021

The paper deals with understanding the concept of language of mathematics for effective teaching and learning of mathematics in a School System. It as well looked at the causes of students’ failure in mathematics in internal and external examinations to include lack of understanding of mathematics language. The persistent poor performance of students in internal and external examinations in mathematics has become an issue of concern to Mathematics educators, and relevant stakeholders.  Findings of recent research studies in mathematics education have identified inadequate understanding of mathematics language to translate word problems into mathematical form as one of the factors responsible for poor performance. Hence, this paper examined the language of mathematics and its understanding. Specifically, the paper discussed the algebraic language; the language of basic operations; the language of set theory; the language of functions; the language of relations; the logical language and the language of differential calculus. The paper further examined the usefulness of variables; difficulties in learning mathematical language and made some recommendations among many others to include that mathematics teachers should teach the mathematical language instruction in mathematics before proceeding to the topic proper to enhance better performances of students in mathematics.
Akhlak and Academic Ethics: Idealism Among Pragmatism in Community Social Life
Authors: Nahar Syamsu , Budianti Yusnaili , Safitri Ro Qoriah Elfi Lina
Published: November 2021

Basically, in social life in achieving progress it is indicated that a person is able to meet the needs of a social group so that that person can contribute to society. Regardless of the intention of a person, one of the efforts made by the community to obtain education is to get a scholarship so that it gets recognition from the community about their social status. If we look at it in today's society, it seems that this view has started to shift because if we see that the award is more to a degree than from one's knowledge. This has prompted some people to take academic degrees with a path that is not in accordance with the procedure. The procedure that was followed was what damaged the social order and academic ethics. It can be said that this degree was obtained based on the objective, namely degree fever. The academic world is a forum whose process always follows academic ethics through scientific activities. Thus academic ethics is essentially a scientific activity that takes place in higher education which includes universal and developing activities. Higher education institutions must be prepared to accept criticism with mutual respect and not engage in discriminatory activities. Violations committed in academic ethics are something that damages and tarnishes the world of education. In order for these educational values to be implemented optimally, we need a rule that can control the process of implementing education; this is what is called academic ethics. The emphasis on the value of honesty in academic ethics consists of two things, namely in writing scientific papers and completing studies. Therefore, it is demanded that every education actor is systematic and comprehensive and requires commitment from various parties to fix problems in education.

Published: November 2021

The development of education in Indonesia must use at least four basic strategies. Namely, The first is equitable distribution of opportunities for education; the second is relevance; the third is quality improvement, and the fourth is efficiency. Generally, this strategy can be divided into two dimensions, namely education improvement and equity. Development of quality improvement is expected to increase the efficiency, effectiveness and productivity of education. "Dimensions of educational equity are expected to provide equal opportunities in obtaining education for all school ages" (Amri, 2013: 68). In realizing distribution of opportunities to obtain education, Surabaya implements a program for acceptance of new students through the path of community partners. The emergence of this policy is also a proof of the government's commitment in carrying out the mandate of the Constitution regarding 20% of the budget for education. This study uses an evaluation research with a qualitative approach. The main data source in this study was obtained by snowball sampling. Data collection techniques in this study used three techniques, namely observation, interviews, and documentation. State High School 13 Surabaya is one of the schools implementing a citizen partner program. The conclusion from this study states that the implementation of the citizen partner program in State High School 13 Surabaya has not yet been reached because of the discovery of elements of nepotism and lack of socialization resulting in one student having not been affected by the community partner program.

The results of this study indicate that the expression of certain reference in the implied implications of the Prophet Muhammad can be identified based on certain sciences, such as mathematics and linguistics. The use of this knowledge base is adjusted to the number and type of certain reference expressions used. By using a certain knowledge base, all definite reference expressions in the explicator can be identified so that the meaning is clear. Clarity of meaning that is associated with the context of communication or shared knowledge in this case is an important property of understanding implicates. For further explained, the expression of reference must be in the process of refinement, the process of refinement is in the explanatory, the exploitation is in the implied speech, the implied speech is in the pragmatic or speaking practice. This shows that the expression of reference must be at the point in speaking activities. The use of definite reference expressions, thus implies high-level speaking skills. Higher-level speaking skills are even better when identifying certain expressions of reference in the speech used requires mastering knowledge in mathematics, linguistics, and so on. In other words, the better the quality of a speech if the speaker is conditioned to operate the multidisciplinary knowledge he has in identifying the expression of certain reference because it has educational value.
