Adsorption and Photocatalytic Activity of Nano-magnetic Materials Fe3O4@C@TiO2-AgBr-Ag for Rhodamine B
Authors: Zheng Xin , Zhang Xinyue , Hu Qili , Sun Hongbin , Wang Linshan , Li Xiaowu 
Published: August 2020

Background:
TiO2 nanoparticles possess adsorption capacity and photocatalytic activity,
and are thus fitted for removal of dyes from water. However, TiO2 nanoparticles are difficult to separate
from the bulk solution due to high loss. Moreover, TiO2 can only use light with a wavelength of
less than 387.5 nm, so the utilization efficiency of solar energy is very low. The present work prepared
Fe3O4@C@TiO2-AgBr-Ag composites to overcome the shortcomings of TiO2.

Objective:
Adsorptive and photocatalytic performance of nano-magnetic materials Fe3O4@C@TiO2-
AgBr-Ag.

Methods:
Fe3O4@C@TiO2 and Fe3O4@C@TiO2-AgBr-Ag magnetic nanocomposites were prepared
by the sol-gel method. Their structure was characterized. Performances of Fe3O4@C@TiO2 and
Fe3O4@C@TiO2-AgBr-Ag for removing Rh B were thoroughly investigated and compared. Langmuir–
Hinshelwood kinetic model was applied to analyze the heterogeneous processes of adsorption
and photodegradation.

Results:
Removal experiments were carried out with Rhodamine B as the subject. The effects of
contacting time, pH, subject concentration, and doses of photocatalyst on the removal performance
were studied. The removal of Rh B by Fe3O4@C@TiO2 and Fe3O4@C@TiO2-AgBr-Ag involved
both adsorption and photodegradation, and the photocatalytic activity of Fe3O4@C@TiO2-AgBr-Ag
was much higher than that of Fe3O4@C@TiO2. The optimum removal conditions were determined.
Under the optimal conditions, the removal rate of Rhodamine B with Fe3O4@C@TiO2 was 77.8%,
and the removal rate of Rhodamine B with Fe3O4@C@TiO2- AgBr-Ag was 87.3%.

Conclusion:
The coupling of the nanostructured metal Ag to the outer surface of TiO2 could effectively
increase photocatalytic efficiency under visible light. The photocatalysts could be separated
from bulk solutions by using a magnet and be easily recycled. The removal reaction kinetics fitted
with the first-order model.

Authors: Ali Nadia A. , Abd-Elnaiem Alaa M. , Hussein Seenaa I. , Khalil Asmaa S. , Alamri Hatem R. , Assaedi Hasan S. 
Published: August 2020

Objective:
In this work, graphene (Gr) or/and Cu particles are used to improve the thermal
and mechanical properties of epoxy resin.

Methods:
Various contents of Gr powder (0.1, 0.3, and 0.5 wt%), and Cu powder (10, 30, and 50
wt%) were loaded to epoxy to form Gr/epoxy and Cu/epoxy composites, respectively. In addition,
hybrids epoxy/Cu/Gr samples were prepared with a selection of the lowest (0.1 and 10) and the highest
(0.5 and 50) ratios of Gr, and Cu, respectively.

Results:
The thermal conductivity increased with the increasing weight ratio of Gr and Cu as compared
to the pure epoxy. The thermogravimetric analysis (TGA) of epoxy composites and hybrid
composites revealed an improvement in the thermal stability. In addition, the mechanical
properties such as hardness shore D and the wear resistance were enhanced for both the epoxy
composites and hybrids composites. However, the Ep+0.5wt%Gr+50wt%Cu hybrid composite
was found to have the maximum hardness 84, with the thermal conductivity of 3.84 W/m.K. It
showed the lowest wear resistance 2.7×10-6 mm3/Nm at loading 10 N.

Conclusion:
The hybrid composite containing 0.5wt%Gr and 50wt%Cu shows the maximum
hardness and thermal conductivity, as well as the lowest wear resistance when compared to
other composites. The physical properties of the hybrid composite can be controlled by the
host blend, and hence the morphology, and interfacial characteristics.
Adrenocortical Crisis Triggered by Levothyroxine in an Unrecognized Autoimmune Polyglandular Syndrome Type-2: A Case Report with Review of the Literature
Authors: Patel Dhruvkumar M. , Gurumikhani Jayanti K. , Patel Mukundkumar V. , Patel Maitri M. , Patel Suyog Y. , Patel Prathna N. 
Published: August 2020

Background:
Autoimmune polyglandular syndrometype-2 (APS-2) is an uncommon endocrine
disorder of Addison’s disease with an autoimmune thyroid disorder and/or type 1 diabetes
mellitus. The diagnosis is more challenging when a patient presents with nonspecific neuropsychiatric
features with hypothyroidism in the setting of unrecognized Addison’s disease.

Case Report:
We report a case of subclinical autoimmune hypothyroidism presented with nonspecific
neuropsychiatric symptoms precipitated by stress. Despite levothyroxine treatment, her symptoms
deteriorated and she was admitted with persistent vomiting and hypovolemic shock. Clinical
features and laboratory parameters were suggestive of underlying adrenocortical insufficiency. Preexisting
autoimmune hypothyroidism combined with Addison's disease confirmed the diagnosis of
unrecognized APS-2. She remarkably improved and her thyroid function tests also normalized with
the treatment of corticosteroids only.

Review of the Literature:
We identified only five published case reports of our title by searching
the database. Neufeld and Betterle have reported their data of APS-2 and concluded that a full-
blown clinical picture of two or more components of the syndrome is like the tip of the iceberg.

Conclusion :
The patients of one major component of APS-2 should be screened for other components
of the disease to pick up latent cases. Addison’s disease should be ruled out in patients of hypothyroidism
who are intolerant to levothyroxine.
Vitamin D Represses the Aggressive Potential of Osteosarcoma
Authors: Tahbazlahafi Behnoosh , Paknejad Malihe , Khaghani Shahnaz , Sadegh-Nejadi Sahar , Khalili Ehsan 
Published: August 2020

Background:
Osteosarcoma (OS) is the basic bone neoplasm with lower survival and
poor prognosis. It is distinguished by its offensive nature and metastatic potential. The fundamental
death source in OS patients is lung metastasis. In addition, the proliferation and cell migration are
thus essential for cancer progression, especially for intrusion and transformation. Several studies
have illustrated that 1,25-Dihydroxyvitamin D (1,25(OH)2D) has a critical role in the growth and
differentiation of bone. However, knowledge of the outcome of 1,25(OH)2D on the progression
and incursion of osteosarcoma cells is minimal.

Objective:
The present study aimed to analyze the effect of different concentrations of 1,25(OH)2D
on the multiplication, progression, and intrusion of OS cells and verify the effective doses of
1,25(OH)2D that can decrease the intensity of the disease and improving the prognosis in OS patients.

Methods:
Saos-2 cells were treated with 1,25(OH)2D (0, 50, 100, and 200 nM) for 48, 72, and 96
hours. Proliferation, invasion, and migration were determined by MTT assay, Transwell assay, and
Scratch test, respectively. The levels of c-Myc and FOXO1 proteins were determined by Western
blotting.

Results:
The proliferation, invasiveness, and migration of Saos-2 cells that were treated with
1,25(OH)2D were significantly decreased compared with untreated cells. Although 1,25(OH)2D
notably decreased c-Myc protein levels (after 48 and 72 hours), FOXO1 protein levels have been
significantly increased after 48 and 72 hours. 1,25(OH)2D and the vitamin D receptor (VDR) suppress
c-Myc function through regulating the c-Myc/MXD1 network and thus, providing a molecular
basis of 1,25(OH)2D related to the cancer-preventive actions.

Conclusion:
Based on the present results, 1,25(OH)2D by targeting c-Myc and FOXO1 expression
displays anti-invasive, anti-migration and anti-proliferative effects on OS cells in vitro. Our findings
suggest that effective doses of the 1,25(OH)2D may reduce the aggressive potential of the OS
cell line. However, further investigation and clinical trials are needed.

Authors: Li Yasha , Wang Huiyao , Chen Kai , Chen Jiamao 
Published: August 2020

Background:
Electrical trees can affect the distribution of electric field and space charge
in cross-linked polyethylene (XLPE) cables, and play an important role in insulation aging and
breakdown of cables. Therefore, it is important to study the influence of electrical trees in cables.

Methods:
In this study, the finite element method of second-order tetrahedral element and electromagnetic
theory method is used for calculation. A model of XLPE cable with three-dimensional
electrical trees is taken as an example for calculation.

Results:
The results show that the longer the trunk length is, the greater the electric field intensity at
the end of the branch is; the farther the electrical trees are from the insulation side of the high voltage,
the more the electric field intensity of each location decreases.

Conclusion:
With the increase of the resistivity of the trees, the electric field intensity and charge
density tend to be stable at the end of the tree.

F-score of 97.25% and kappa value of 90.52%.

Conclusion:
The experimental results pointed out that a maximum classification performance was
attained by the proposed model on all different aspects. The proposed method helped in determining
the capability of a borrower in repaying the loan and computing the credit risks properly.
Considerações sobre o estrato fonológico na descrição sistêmico-funcional de textos instanciadores de gêneros orais
Authors: Sousa Camila Stephane Cardoso , Clementino Moura Ana Célia 
Published: August 2020

A aplicação do aparato sistêmico-funcional às análises de textos instanciadores de gêneros orais em língua portuguesa, em geral, não considera aspectos do estrato fonológico. A fim de demonstrar sua relevância, em especial, para a descrição de textos orais, neste trabalho, buscamos: (1) estender o sistema de funções de fala à descrição de outras tipologias de textos orais para além da tipologia conversacional; e (2) demonstrar a aplicação descritiva dos aspectos entoacionais por meio dos sistemas de tom, tonalidade, tonicidade e ritmo a fim de nortear a identificação da unidade semântico-discursiva de movimento. Nossa proposta segue o modelo de descrição do estrato fonológico, desenvolvido em Halliday e Greaves (2008), as aplicações ao português propostas por Cagliari (1981, 2012), bem como a proposta de relação entre os critérios prosódicos e o sistema semântico-discursivo de funções de fala, desenvolvido por Eggins (1990) e ampliado em Slade (1996) e Eggins e Slade (2006). Realizamos a análise do estágio de orientação de dois textos instanciadores de gêneros orais, a partir das seguintes categorias: classe de movimentos, modos oracionais, ritmo, tons e grupos tonais. Nossos resultados revelam a identificação de movimentos com base nos critérios prosódicos e lexicogramaticais em textos não conversacionais, constituindo sequências monologais continuativas, que cumprem a função de prover mais informações acerca da narrativa construída, e sequências interacionais não continuativas, revelando que o aspecto interacional é resultado da funcionalidade de movimentos e não do número de participantes.
La teoría administrativa en el contexto emergente
Authors: Mendoza de Ferrer Hermelinda , Rodríguez María 
Published: August 2020

<p>La investigación tuvo por fi nalidad analizar desde las categorías: sujeto, realidad, racionalidad y poder, los cambios que se han venido gestando a lo largo del establecimiento<br />de un orden social emergente a raíz del avance de las tecnologías de la información y comunicación, a fi n de establecer su impacto en el ámbito de la Teoría Administrativa, específi camente en el campo gerencial. Para este análisis se hizo uso de la estrategia documental desde el enfoque hermenéutico. Se concluye que la concepción adoptada respecto a los elementos analizados se constituye en un sistema de pensamiento que invade la gerencia, orientando sus acciones y decisiones tendentes a lograr mayor productividad y rentabilidad organizacional. En este tenor se observa que, el pensamiento gerencial se moviliza hacia la Gerencia Cualitativa Humanística, cuyo fundamento es el hombre, aun cuando se evidencia incongruencia<br />entre lo que se dice y lo que se hace, entre el ser y el hacer, posiblemente como consecuencia de la situación de transitoriedad que se vive.</p>

Paradigma Sufistik Tafsir Al-Qurâ€™an Bediuzzaman Said Nursi dan Fethullah Gulen
Authors: Fawaid Ah. 
Published: August 2020

Artikel ini hendak mengkaji tafsir sufistik Said Nursi dan Fethullah Gulen, persamaan dan perbedaan keduanya. Dengan menggunakan teori sejarah sosial pemikiran tafsir, tulisan ini mengungkapkan bahwa baik Nursi maupun Gulen sama-sama menggunakan paradigma sufistik dalam penafsiran Al-Qurâ€™an. Paradigma sufistik dalam penafsiran Al-Qurâ€™an menjadi cara efektif yang digunakan untuk mereka yang hidup di lingkungan â€˜sekulerâ€™, sehingga keduanya memilih â€˜suasana sejukâ€™ guna menularkan pengetahuan Qurâ€™ani ke komunitasnya yang digempur gelamornya peradaban Barat dengan sistemnya yang sekuler. Paradigma sufistik yang dikembangkan Nursi dan Gulen tidak sepenuhnya menjinakkan akal di samping hati dan jiwa. Ketiga-tiganya digunakan secara seimbang dalam mengarungi samudera Al-Qurâ€™an. Selain itu, apa yang dilakukan Nursi, dan khususnya Gulen, sekaligus membantah apa yang diragukan Ignaz Goldziher bahwa tasawuf merupakan doktrin asing dari tradisi Islam. Baik Nursi maupun Gulen merupakan tokoh yang lebur bersama komunitasnya, sehingga cakrawala tafsir yang dihasilkan lebih bernuansa populis, ketimbang perdebatan akademis.

Authors: Stratopoulos Theophanis C. 
Published: August 2020

ABSTRACT
The objective of these teaching notes is to provide an outline for offering blockchain related foundational knowledge to accounting students so they can evaluate and prepare for the effect of blockchain on the accounting profession. The approach is driven by the following principle: Given that accounting students do not want to become programmers or cryptographers, what is the essential blockchain knowledge that they need to know? Based on my own teaching and research experience, I propose and explain how I use a combination of storytelling and scaffolding approach to focus on the delivery of the following topics: (1) why study blockchain? (2) general foundational knowledge (i.e., element of complete transactions and double spending), (3) interactive exercises to explain technical knowledge on topics such as hashing and proof-of-work (mining), and (4) blockchain implementation in a supply chain setting.
A ‘História Monumental’ de dois heróis: Historiografia Linguística
Authors: Silva Michael Soares 
Published: August 2020

Seria a polarização das ideias o que torna a ciência uma instigante sucessão de evoluções, ou, as ideias contrárias não são necessárias para manter uma disciplina em órbita e vigor pluridimensional? Assim, Cristina Altman definiu estar a ciência extremamente complexada pelas polarizações. A Conferência, mencionada no ciclo de Conferências da ABRALIN AO VIVO 2020, teve o título idêntico ao curso de pós-graduação que ela proferira em 2017 na Faculdade de Letras da USP: “A Guerra Fria Estruturalista”, em que fui aluno especial, e, por isso; ponho-me à composição desse ofício. Neusa Bastos (prof. Dra. PUC/SP) fez a apresentação da conferencista. A relevância internacional de Cristina Altman não está em suas partidas ao exterior, mas especialmente pela recepção no Brasil, por exemplo de Pierre Swiggers e David Ernst Frideryk Konrad Koerner. A formação da linguista prima pela disciplina da Historiografia Linguística, ao qual se centra “A Guerra Fria Estruturalista”.
Scientific Research Work in the Central Libraries of the Russian Federation: Legal Basis, Organization Forms and Key Problems
Authors: Lodygina Polina A. 
Published: August 2020

The purpose of this article is to identify organizational problems of conducting scientific research work (R&D) by the regional libraries and the possibility of applying the experience of national libraries in the organization of science, taking into account the requirements for scientific research institutions. The article analyzes the legal and organizational grounds for conducting scientific research work by libraries and the experience of national libraries of Russia. The author indicates that the role of leading scientific institutions in the library sphere is assigned to the National Library of Russia and The Russian State Library.The article presents comprehensive analysis of the state of research activities of the central libraries of the subjects of the Russian Federation (CL of RF subjects) on the basis of reflection of this work in the normative legal acts of regional level, governing library operations, and in the regulations of the libraries. Specialized scientific research divisions are studied based on the action plans, public reports, etc. Conducting scientific research in library is one of the determinative types of library activities. The results of studies of central libraries are recognized both at the regional and federal levels and proved by the winners of the All-Russian competition of scientific works on library science, bibliography and book science, the All-Russian competition “The best professional book of the year”, the All-Russian competition “Library analytics”, the All-Russian competition of library innovation and others.The author notes that the identified scientific potential of the CL of the RF subjects is not fully used. The paper concludes that there is insufficient attention to this area of activity from federal authorities and libraries — to the methodical and coordination centres of federal level. The article outlines the prospects and directions for solving the issue of validity and significance of scientific research conducted by regional libraries. The author points out the need for methodological support by national libraries.
