Hellinger–Reissner variational principle for a class of specified stress problems
Authors: Wang Jialin , Zhang Junbo , Chen Zhuo , He Lin 
Published: January 2022

Abstract
Aiming at the problem of the specified stress condition in a partial region of the structure, the Hellinger–Reissner (H–R) variational principle is studied to provide a theoretical basis for the finite element numerical analysis. By introducing the unknown non-elastic strain as an additional unknown quantity to fulfill the specified stress condition, the elastic mechanics governing equations for the specified stress problem are given. Both stress and unknown non-elastic strain are taken as independent variables to establish the complementary energy principle and virtual work equation which are equivalent to the elastic mechanical control equation of the specified stress problem. Based on the conventional H–R variational principle, using displacement, stress and unknown non-elastic strain as independent variables, a H–R variational functional that satisfies the specified stress conditions is established by using Lagrange multiplier method. Also the variational functional with displacement, elastic strain and unknown non-elastic strain as independent variables is deduced by transforming the stress into the elastic strain. The corresponding finite formulae are derived based on an intra-element stress hybridization method. The H–R variational principle for the specified stress problem takes non-elastic strain as an independent variable, so that the stress explicitly appears in the equilibrium equation of the element and structure, which expands the application range and capabilities of the existing variational principle and finite element method. The correctness and accuracy of the theory and algorithm are verified by numerical examples.
Preliminary investigation of serum ferritin level and its reference interval in apparent healthy children population in Provincial Children’s Hospital
Authors: Zhang Xiucai , Huang Shumin , Xu Hui 
Published: January 2022

Abstract

Objectives
Serum ferritin (SF) is a biomarker of physiological iron stores. Reference intervals for ferritin about children are the subject of some controversy.

Methods
SF was assayed on Beckman analyzer. All results were retrieved from the electronic medical record (3,344 samples). Student’s t test and one-way ANOVA test were applied to compare two groups, with respect to continuous and discrete variables.

Results
The reference range of SF on reference population was 8.40–95.98 µg/L. Among the male, there was no significant difference in the average level between the 0–1 years old group and the 1–3 years old group, but there were significant differences between the other groups and the previous group. In terms of women, there was no significant difference in the average level of ferritin between the 1–3 years old group and 9–17 years old group and the previous group, but there were significant differences in the average levels of ferritin in other groups.

Conclusions
We established the reference intervals of ferritin of different age groups and gender groups. Our results have practical significance for the formulation of clinical reference range, which would be helpful in interpreting laboratory data and clinical decision-making.
Effect of Different Heat Treatments with and without Deep Cryogenic Treatment on the Morphology of Mg17Al12Intermetallic Phase and Hardness of AZ91 Magnesium Alloy

Published: January 2022

AbstractIn this study, dissolution of the Mg17Al12phase carried out at 413 °C within 24 h and process followed by cooling the samples in different media with various cooling rates. Some samples were directly aged and others were held in liquid nitrogen for 24 h prior to aging. In this study for investigation of microstructure, the specimens were studied using a Meiji optical microscope and Scanning Electron Microscopy and Energy Dispersive Spectroscopy analysis was used to characterize the chemical composition of the phases. Results showed that at low cooling rates, a large amount of discontinuous precipitations were formed and by increasing the cooling rate, their amount reduced and their number and sizes decreased. Application of the deep cryogenic treatment with aging causes the dimensions of the secondary phases to be slightly larger than that of the non-deep cryogenic treatment state. Deep cryogenic treatment especially in samples with high cooling rate causes reducing the amount of Al, compared to usual stoichiometric value by formation of shrinkage stress in two stages (cooling after solutioning and deep cryogenic treatment). Deep cryogenic treatment in all of the samples increased the hardness, compared to the case without deep cryogenic treatment, by increasing the amount of Al out of the structure and providing conditions for the formation of more continuous and discontinuous phases.

Harminc év mérlege.
Authors: Kozma Tamás 
Published: January 2022

Összefoglaló. Ennek az írásnak a célja kettős. Egyrészt bevezetés
kíván lenni a Harmincéves az Educatio további tanulmányaihoz;
másrészt pedig visszapillantás az EDU 1992–2018 között szerkesztett
Mérleg-számaira. Ezek a számok olvashatók mind papír
alapon, mind pedig online formában. Ami nem olvasható, az a
keletkezéstörténetük. A Mérleg-számok ötletéről, a szerkesztés
körülményeiről, a szerkesztés körüli vitákról, valamint a megjelenés körüli
izgalmakról szól ez a cikk. Fejezeteit az egyes Mérleg-számok
alkotják, amelyek átfogják az EDU három évtizedes történetét. Célunk nem az
volt, hogy megírjuk az Educatio® történetét. Hanem hogy
felelevenítsük a szerkesztés hátterét, konfliktusait, levegőjét. Így ez az
áttekintés mind az EDU30-hoz, mind a Mérleg-számok
keletkezéséhez hozzájárul.
Summary. The purpose of this writing is twofold. On the one hand, it
is an introduction to further studies of the present publication of
Educatio®. On the other hand, it is a look back at the
Journal’s issues focused on education policy evaluation compiled every four
years between 1992 and 2018. These thematic issues can be read both on paper and
online. What cannot be read is their history of origin. The present article is
about the idea of education policy evaluation, the circumstances of organising,
the debates on editing, and the excitements around their appearance. The writing
covers three decades of the Journal, and is structured by the four-year periods
of its outcoming. Our goal was not to write a complete history of
Educatio®. Instead, to highlight the background, the
conflicts, and the atmosphere of evaluating government policies. Thus, the
writing contributes to both the present issue and the career path of
Educatio®.

ABSTRAK
Penelitian ini dilakukan untuk mengetahui penerapan objektivitas dari pemberitaan penahanan Habib Rizieq Shihab yang dirilis media online Detik.com pada Desember 2020 lalu, dikaji dengan prinsip faktualitas dan prinsip imparsialitas model Westerstahl. Metode yang digunakan pada penelitian ini yaitu studi deskriptif dengan teknik analisis isi. Mengacu pada teori objektivitas yang dikemukakan Denis McQuail yang dapat mengukur keobjektifan sebuah berita dilihat dengan faktualitas dan imparsialitas yang diterapkan pada berita tersebut. Hasil penelitian menunjukkan bahwa media online Detik.com belum sepenuhnya menerapkan prinsip objektivitas. Kriteria faktualitas berita tersebut sudah diterapkan karena berita mengandung unsur 5 W + 1 H, informasi yang disajikan merupakan informasi baru, serta adanya kesesuaian antara judul dan isi berita. Sedangkan kriteria imparsialitas belum sepenuhnya diterapkan karena tidak memasukkan pernyataan dari dua belah pihak, serta terdapat opini dari pembuat berita yang terkesan menyudutkan salah satu pihak.
ABSTRACT
This study was conducted to determine the application of objectivity from the news of the detention of Habib Rizieq Shihab which was released by the online media Detik.com in December 2020, studied with the principle of factuality and the principle of impartiality of the Westerstahl model. The method used in this research is a descriptive study with content analysis techniques. Referring to the objectivity theory put forward by Denis McQuail which can measure the objectivity of a news seen by the factuality and impartiality applied to the news. The results show that the online media Detik.com has not fully implemented the principle of objectivity. The factuality criteria of the news have been applied because the news contains elements of 5 W + 1 H, the information presented is new information, and there is a match between the title and content of the news. While the impartiality criteria have not been fully implemented because they do not include statements from both parties, and there are opinions from news makers who seem to corner one parties.

The world is currently facing an energy crisis. This research was conducted to create alternative energy by utilizing abundant biomass in nature. The novelty of this study: (1) Use of soybean biomass with coconut water as an electrolyte paste, (2) Testing of bio-battery resistance to wall clocks, and (3) Comparison of the composition of the two materials. In this study, an electrolyte paste made from soybeans (SBs) and coconut water (CWs) with a ratio of 7/1, 6/2, 5/3, 4/4, 3/5, 2/6, and 1/7. To support the analysis, an electrical voltage test and a battery resistance test for wall clocks were carried out. The experimental results show that the composition of coconut water increases the value of the electric voltage on the bio-battery. The composition of coconut water serves to activate the ions in the paste. Meanwhile, more soybean content will increase bio-battery life. It was found that the bio-battery with electrolyte paste of soybeans and coconut water can be used as alternative energy. The results of this research are expected to offer renewable alternative energy for world energy security.
The Supply of Authorized Providers for Medication-Assisted Treatment in Ohio
Authors: Pitcher Ariana , Xu Wendy Yi 
Published: January 2022

Background: Ohio experiences among the highest drug overdose rates nationally. The Drug Addiction Treatment Act (DATA) of 2000 permits qualified clinicians to use medication-assisted treatment (MAT) to treat opioid dependency. This study characterizes clinicians authorized to perform MAT and examines whether these clinicians are geographically collocated in areas with higher opioid burdens. Methods: Data of DATA providers in 2019 came from the Substance Abuse and Mental Health Administration. Opioid overdose mortality rates were extracted from the County Health Rankings and Roadmaps to represent disease burdens in local areas. The DATA provider density is represented by the number of DATA-waivered providers per 100 000 population for each county. We used Pearson correlational tests to examine the correlations between the local DATA provider density and the opioid mortality rate.Results: Most of the DATA providers were physicians (57%), followed by nurse practitioners (27%) and physician assistants (4%). The average waivered provider density was 13.90 per 100 000 population. The local density of DATA providers and local opioid overdose death rates are moderately correlated (P < 0.001).Conclusion: Physicians still represent most waivered providers in Ohio. While DATA providers were located in some areas with high needs for opioid treatments, our data suggest that other areas with high opioid burdens likely have an inadequate workforce supply to reduce opioid burdens. Without an adequate DATA workforce, policies that focus on MAT care access to address the opioid epidemic may be in vain.
The influence of ICT instruments on a transmission of interest rates by business entities and public authorities – A scientific comment
Authors: Hadasik Bartłomiej 
Published: January 2022

Purpose of the study: This article aims to present the role played by electronic communication tools from the economic and investor perspective. The paper focuses on three axes: ICT for a transmission of information on interest rates, ICT as a source of information for investors and ICT for improving market efficiency.
Methodology: The article is exploratory in nature, which means that in order to investigate the individual pillars of this work, an analysis of the corresponding literature sources has been made. An extensive review of scientific articles, scientific books, and working papers corresponding to individual axes was made.
Main Findings: ICT tools show an advantage over other (more traditional) communication channels, which is reflected in more dynamic and immediate market reactions. High use of these tools is observed both among enterprises and central agencies. The effective transmission of information about interest rates minimizes the risk of making wrong investment decisions. However, it is important to bear in mind the challenges of, inter alia, still low level of digital literacy among the society.
Applications of the study: This work may be an incentive for entrepreneurs to digitize their companies more widely, but also for investors to use ICT to make investment decisions more accurately.
Novelty/Originality of the study: The paper presents a broad literature overview on using ICT tools in economic applications, including investment. The starting point is also behavioral decision-making theories along with classical heuristics.
The rise of China and the US-Europe alliance drift in the 2010s: A lost decade for the European Union?
Authors: Pagán Sánchez Antonio José 
Published: January 2022

The United States and its allies within the European Union have been unable to forge a common response to deal with the rise of China. Even though China’s growing global presence might undermine the international position of the United States, Washington’s European allies have sometimes refused to close ranks with their American ally. And more importantly, European engagement with China during the last decade has lacked internal consistency and cohesion, to the point that the European Union has rarely been the relevant actor when it comes to shaping Europe-China relations. This is the conclusion reached by this paper after analyzing the EU’s behavior on the Asian Infrastructure Investment Bank, the Belt and Road Initiative, the adoption of Huawei’s 5G technology and the consideration of China as a threat within NATO’s framework. The European Commission has been unwilling or unable to unite the member states around a common position on these four cases. However, the findings of this article also support the idea that an embryonic model of strategic autonomy was already underway during the last decade, and that the growing awareness within the EU about the importance and implications of China’s rise brings new geopolitical opportunities for the union.

Published: January 2022

O artigo tem como base a estrutura produtiva do estado do Maranhão e sua distribuição em escala regional, e objetiva analisar a evolução do emprego formal, no período 2006-2016. Tal recorte temporal se justifica, pois vincula-se à compatibilização das atividades econômicas entre as principais fontes de informações utilizadas: a Relação Anual de Informações Sociais (RAIS)e o Sistema de Contas Regionais.Já o recorte espacial toma como referência as Regiões Imediatas, definição elaborada pelo IBGE, que substituiu as antigas microrregiões.Para tanto, utiliza a metodologia de adaptação do índice de Herfindhal-Hirschman para calcular os diversos setores de atividade, em conjunto com um modelo de regressão para estimar valores de elasticidade do emprego-valor adicionado setorial.EVOLUTION OF FORMAL EMPLOYMENT IN MARANHÃO IN THE PERIOD 2006-2016AbstractStarting from the productive structure of the state of Maranhão and its distribution on a regional scale, the objective is to analyze the evolution of formal employment in the period 2006-2016. This time frame is justified, as it is linked to the compatibility of economic activities between the main sources of information used: the Annual Social Information List (RAIS)and the Regional Accounts System. The spatial cutout, on the other hand, takes as reference the Immediate Regions, a definition elaborated by the IBGE, which replaced the old micro-regions. The methodology used was the adaptation of the Herfindhal-Hirschman index to calculate the different sectors of activity, together with a regression model to estimate sectoralemployment-value added elasticity values.Keywords: Productive structure; Formal employment; Maranhão; Immediate regions.
НОВЫЕ ДАННЫЕ ПО ВОЗРАСТУ УГЛЕНОСНЫХ ОТЛОЖЕНИЙ ЮГО-ЗАПАДНОГО ПРИМОРЬЯ И ИХ ЗНАЧЕНИЕ ДЛЯ СТРАТИГРАФИИ КАЙНОЗОЯ ДАЛЬНЕВОСТОЧНОГО РЕГИОНА

Чекрыжов, В.Б. Хубанов, Цуцуми Юкиясу, С.А. Чащин // Известия Томского политехнического университета. Инжиниринг георесурсов. – 2022. – Т. 333. – № 1. – С. 15-25
Актуальность исследования обусловлена необходимостью устранения существующих расхождений во взглядах на возраст палеогеновых промышленно-угленосных отложений на юго-западе Приморья и сопредельных территориях. Цель: осуществить U-Pb-датирования цирконов из третичных образований, встречающихся в пределах Хасанской рифтогенной впадины, что позволит в дальнейшем уточнить схему последовательности их формирования на территории юго-западного Приморья. Объекты: осадочные породы хасанской и назимовской свит, а также риолиты краскинского комплекса. Методы. Изучение зональности и внутренней структуры цирконов выполнено электронным микрозондом JXA-8100, оснащенным катодолюминесцентным детектором, U-Pb-изотопные исследования цирконов были проведены LA-ICP-MS-методом. Результаты. Согласно полученным результатам U-Pb-датирования цирконов из третичных образований Хасанской впадины, установлено, что возраст самой молодой популяции цирконов в песчаниках назимовской и хасанской свит составляет 37–38 млн лет, что соответствует позднему эоцену и совпадает с возрастной оценкой формирования этих свит, полученной ранее по результатам изучения микро- и макрофлоры. Установлено, что поступление цирконов самой молодой популяции в песчаники хасанской (=назимовской) свиты связано с размывом верхнеэоценовых кислых пород краскинского комплекса. Соответственно, это позволяет говорить об одновозрастности вышеперечисленных стратонов и наличии в пределах Хасанской депрессии в кайнозое одного, позднеэоценового, этапа углеобразования, а не двух, как считалось ранее. Это значительно упрощает региональную стратиграфическую шкалу применительно к Хасанской впадине и ее аналогам в других впадинах Приморья и соседних регионах юга Дальнего Востока России.
