Published: December 2021

Eleutherine americana (E. americana) is a medicinal plant commonly found on the island of Borneo, Indonesia. This plant is known to have several biological activities. However, anthraquinone residues are generally present as contaminants. This study was aimed to develop a method of determining the levels of 9,10-anthraquinone in plant extracts and fractions using High Performance Liquid Chromatography (HPLC). The research aims to optimize the mobile phase, the system suitability test, and the system validation. The optimal mobile phase was acetonitrile:distilled water 1:1 v/v with a flow rate of 1.25 mL/min. The validation result shows that the linearity was obtained with a correlation coefficient (r) of 0.9995 and an r2 coefficient of 0.9991. The estimated limits for detection and quantification values were 0.178 and 0.594 µg/mL, respectively. In the intraday and inter-day accuracy test, the coefficient of variance for reference was 0.627 and 0.774, while the results for the sample were 2.966 and 2.658. The percentage recovery rate for reference was between 98.976–101.452%, and for the sample, the result was 89.191–94.667%. The average 9,10-anthraquinone content in the acetate fraction of E. americana plant was 9.799 µg/g ± 5.243.

Published: December 2021

The biotransformation and biodecolorization of methylene blue (MB) dye using the bacterium Ralstonia pickettii was investigated. This experiment was conducted in a nutrient broth (NB) medium after adding MB at 100 mg L–1 concentration. Approximately 98.11% of MB was decolorized after 18 h of incubation. In addition, the metabolic products detected by LC-TOF/MS were Azure A (AA), thionine, leuco-MB, and glucose-MB, which indicated the MB degradation through a reductase that attacked the heterocyclic central chromophore group present in the structure. Moreover, azure A and thionine fragments resulted from the N-demethylase enzyme that attacked the auxochrome group. Thus, this research was assumed to be the first scientific report suggesting the potential to use R. pickettii in the biodecolorization and biotransformation of dye waste, particularly MB.

West Nile virus (WNV) is among the other four flavivirus genus, rapidly spreading worldwide. The number of cases increases globally as there are no clinically available approved drugs and vaccines against this disease. Based on our previous finding related to a flavivirus, a series of spiropyrrolidine derivatives were regioselectively synthesized via [3+2]-cycloaddition reaction of three components between isatins, sarcosine, and (E)-3,5-bis (arylidene)-4-piperidones. The yield of synthesized compounds was in a range between 81–95%. The structures of all the synthesized compounds were characterized using FT-IR, 1D- and 2D-NMR, and HRMS. Molecular docking studies of spiropyrrolidines on NS2B-NS3 protease were done to understand and explore the ligand-receptor interactions and hypothesize the drug's refinements. The inhibition of NS2B-NS3 protease has been considered a promising strategy because this enzyme is responsible for the viral replication process. Among them, compound 5c shows an excellent binding affinity with ‒7.71 kcal/mol free binding energy and an inhibition constant of 1.73 μM. It also showed the binding orientation into the active site of WNV NS2B-NS3 protease on Asn84, Tyr1161, Gly1151, and Gly1153.

Published: December 2021

Due to their toxicity, Cd(II) and Ni(II) ions in the environment are severe. The hydroxyapatite composite was improved with magnetic MnFe2O4 to remove Cd(II) and Ni(II) ions from an aqueous solution. Hydroxyapatite was extracted from Snakehead (Channa striata) fish bones via alkaline-heat treatment. The hydroxyapatite/MnFe2O4 composite performance was analyzed through XRD, FTIR, SEM-EDS, BET analysis, and VSM, and the results reveal that the hydroxyapatite/MnFe2O4 composite shows good magnetic properties of 21.95 emu/g. The kinetics evaluation confirmed that the pseudo-second-order kinetics model was more suitable to describe the adsorption of Cd(II) and Ni(II) ions by hydroxyapatite/MnFe2O4 composite from the solution. The Langmuir isotherm model was suitable to describe the adsorption process of the Cd(II) and Ni(II)  ions, where the adsorption capacities for Cd(II) and Ni(II) are 54.3 and 47.4 mg/g, respectively. Desorption of Cd(II) and Ni(II) ions from hydroxyapatite/MnFe2O4 composite using NaCl as the eluent was more effective than EDTA. The findings of this study indicate that hydroxyapatite/MnFe2O4 can reduce Cd(II) and Ni(II) ions in wastewater so that it can recover natural resources.

We perform ﬁrst-principles calculations to investigate the adsorption process of methyl mercury (MeHg) on germanene with the presence of water molecules. We calculate the formation energy and density of states to determine the effect of the adsorption of MeHg on the structural and electronic properties of germanene. Our results show that MeHg is chemisorbed on germanene through a spontaneous reaction. The calculated formation energy of the system is -1.61 eV. We also carry out charge distribution and charge transfer calculations based on the Mulliken model to understand the adsorption mechanism of MeHg.

New transition metal complexes of cobalt(II), nickel(II), copper(II), palladium(II), cadmium(II), and platinum(IV) with bidentate ligand 4-amino-5-(3,4,5-trimethoxyphenyl)-4H-1,2,4-triazole-3-thiol were synthesized and characterized by microelemental analyses (CHNS), Fourier-transform infrared (FT-IR), UV-Visible spectra, molar conductance, magnetic susceptibility and thermal analyses (TG-DSC). The ligand was synthesized by ring closure of potassium-2-(3,4,5-trimethoxybenzoyl) hydrazine carbodithioate with an excess amount of hydrazine, and then was acidified using hydrochloric acid. The ligand was used as Lewis bases to prepare metal complexes through the reaction of ratio (1:2) metal:ligand. The ligand was characterized by 1H-NMR and 13C-NMR and the previously described methods to identify the complexes. The results obtained from spectra and elemental analyses indicated the tetrahedral geometry around Cd(II) ion, square-planar for Cu(II) and Pd(II), and octahedral geometry around Co(II), Ni(II), and Pt(IV). All the metal complexes showed significant antibacterial activity in comparison with the free ligand. The antibacterial test of the platinum(IV) complex showed higher activity than other metal complexes against bacteria Staphylococcus aureus (G-positive) and Escherichia coli (G-negative).

SOCIAL EXCLUSION OF DEMI-MONDAINE AND NYAI IN FRENCH AND INDONESIAN NOVELS
Authors: Hayuningsih Arifah Arum Candra
Published: December 2021

One of the interesting themes but not widely featured in Indonesian and French literatures in the 19th and 20th centuries is nyai and demi-mondaine. Both have a similar meaning, namely the mistress of a man from the upper-middle class. This study looks at the exclusions that occur in the lives of nyai and demi-mondaine in an Indonesian novel titled Bumi Manusia by Pramoedya Ananta Toer and a French novel titled La Dame aux Camélias by Alexandre Dumas (philosophers). The analysis was carried out using Fairclough’s critical discourse analysis approach to examine the exclusion process in the two novels, which describes the realities that occur in society. This study found that the mistresses are excluded primarily through labeling and stereotyping. Despite the exclusion from the discourse of ‘honor’ in society, the mistresses find their own way of surviving in a society that does not like them.Salah satu tema menarik namun tidak banyak ditampilkan dalam karya sastra Indonesia dan Prancis di abad 19 dan 20 adalah kehidupan nyai dan demi-monde. Keduanya memiliki pengertian yang hampir serupa, yakni perempuan simpanan dari seorang laki-laki kelas menengah ke atas. Sikap masyarakat yang cenderung merendahkan mereka dapat dipandang sebagai proses eksklusi. Penelitian ini menelusuri bagaimana ekslusi yang terjadi dalam kehidupan nyai dan courtesan di Indonesia dan Prancis seperti yang ada pada novel Bumi Manusia karya Pramoedya Ananta Toer dan novel La Dame aux Camélias karya Alexandre Dumas (fils). Analisis dilakukan dengan metode analisis wacana kritis dari Fairclough untuk melihat proses eksklusi di kedua novel tersebut, yang merupakan gambaran dari realita yang terjadi di masyarakat. Penelitian ini memperlihatkan bahwa proses eksklusi paling banyak terjadi melalui labelling dan stereotyping. Meski demikian, para perempuan simpanan yang mengalami eksklusi dari wacana ‘kehormatan’ di masyarakat memiliki cara sendiri untuk bertahan di tengah masyarakat yang tidak menyukai mereka.

Authors: Urun Goker Mubeher
Published: December 2021

The job of being an English language instructor is both demanding and challenging. Recently many researchers have been paying attention to determine teachers’ attitudes, burnouts, and self-efficacy towards the subject and to find a relationship between those psychological concepts and certain variables. However, there is not much research done in the field of English language teaching in North Cyprus, Turkey, and in the Middle East regarding EFL teacher burnout and self-efficacy. This study aimed to investigate the perceived levels of burnout among EFL Instructors at the English Preparatory Schools in Girne American University, Near East University and the European University of Lefke in North Cyprus using the Maslach Burnout Inventory-Education Survey developed by Friedman. The study, in which 51 EFL instructors participated found that instructors experienced low levels of emotional exhaustion, low levels of depersonalization in relationships with students, colleagues, and others, and a high level of personal accomplishment in their work. An EFL instructor’s age, marital status, work experience, weekly teaching hours, job status, native or non-native status do not seem to influence instructors’ responses on each of the sub-scales of the Maslach Burnout Inventory. However, variables gender and the university they work to influence their responses related to emotional exhaustion, but they do not influence their responses related to depersonalization and personal accomplishment scores on the Maslach Burnout Inventory.
Does Information Asymmetry Influence Hi-tech Entrepreneurial Financing?
Authors: LIU Anthony
Published: December 2021

Exploring the effective ways of start-up financing is an important and practical issue to technological innovation and economic development. This paper aims to investigate the impacts of information asymmetry on the high-tech start-up financing preference, and whether an entrepreneur’s internationality features moderate the main effects. A sample of 500 high-tech start-ups and new ventures was collected at Shenzhen, China. Regression models are designated for testing both the main effects predicted in research hypotheses and the predicted moderating role of an entrepreneur’s internationality features. Our test results lead to 3 findings: firstly, in the high-tech industries, the information asymmetry mitigated by disclosing intellectual properties can significantly increase the start-up preference for external financing. This finding can be explained by the reduction of agency costs of debts. Secondly, the lessened information asymmetry can shorten the life cycle of start-up financing under the pecking order hypothesis. Lastly, the liability of foreignness is observed to have a significant positive moderating role on the main effects under the investigation. It can be concluded that the information asymmetry and the liability of foreignness are crucial factors influencing start-up financing decisions.This conclusion implies that reducing the information asymmetry by adequately disclosing technological strength and tacit knowledge can benefit the entrepreneurial financing for the high-tech start-ups and new ventures at the early stages, as well as provide an effective shortcut to the start-up financing cycle. Furthermore, the introduction of overseas technologies, funds, knowledge, experiences, and entrepreneurship into the high-tech start-ups does not create the liability of foreignness, and on the contrary, it is an “asset” that can help improve entrepreneurial financing decisions.

Published: December 2021

The computational study of structures with chemical relevance is preceded by its modeling in such manner that no calculations can be submitted without the knowledge of their spatial atomic arrangement. In this regard, the use of an object-oriented language can be helpful both to generate the Cartesian coordinates (.xyz file format) and to obtain a ray-traced image. The modeling of chemical structures based on programming has some advantages with respect to other known strategies. The more important advantage is the generation of Cartesian coordinates that can be visualized easily by using free of charge software. Our approach facilitates the spatial vision of complex structures and make tangible the chemistry concepts delivered in the classroom. In this article an undergraduate project is described in which students generate the Cartesian coordinates of 13 Archimedean solids based on a geometrical/programming approach. Students were guided along the project and meetings were held to integrate their ideas in a few lines of programmed codes. They improved their decision-making process and their organization and collecting information capabilities, as much as their reasoning and spatial depth. The final products of this project are the coded algorithms and those made tangible the grade of learning/understanding derived of this activity.

Authors: Reddy Pallapu Himavanth
Published: December 2021

Abstract: Cloud computing provides customers with storage as a service, allowing data to be stored, managed, and cached remotely. Users can also access it online. A major concern for users is the integrity of the data stored in the cloud, as it is possible for external invaders or criminals to attack, repair, or destroy the data stored in the cloud. Data auditing is a trending concept that involves hiring a third-party auditor to perform a data integrity test (TPA). The main purpose of this project is to provide a safe and effective testing system that combines features such as data integrity, confidentiality, and privacy protection. The cloud server is only used to store encrypted data blocks in the proposed system. It is not subject to any additional computer verification. TPA and the data owner are in charge of all the functions of the scheme. A variety of materials are used to evaluate the proposed audit process. The proposed solution meets all the processes while minimizing the load on cloud servers. Data dynamics actions such as data review, deletion, and installation will be performed in the future.

Authors:   Edo State Study Centre,, Okolie Ugo Chuks , Osayande Festus ,   University of Benin
Published: December 2021

Nigeria is a plural state with diverse culture, ethnic and religious institutions. These portray the beauty of the country to the outside world and successive Nigerian governments have not ceased to preach the nation’s desire to forge unity in diversity. However, the reality on the ground is that ethnic chauvinism, ethnic politics, ethnic consciousness, ethnic factionalization, religious fanaticism and extremism have overshadowed the desire for unity, which is a basic ingredient for national development. These are manifested in political and constitutional instabilities, ethnic and religious violence, bad leadership and governance, political competition for power, insecurity of lives and property, corruption, tribalism and nepotism, injustice, immoral acts, bloodshed, and intolerance. The challenges of national development in Nigeria assume such an awful proportion that seems to defy any kind of antidote; this is the stage at which the concept of secularism becomes most apt. This study therefore explored the effect of secularism on national development in Nigeria’s fourth republic. A descriptive method was adopted and data was collected via a survey of 900 respondents comprises of Christian leaders, Muslim leaders, Traditional leaders, leaders of Civil Society groups and Youth leaders. Data collected were analysed using Pearson product moment correlation and linear regression analysis. The result of the study revealed that there is a positive and significant relationship between secularism and national development. The result also showed that secularism does have a significant effect on national development in Nigeria’s fourth republic. Requisite recommendations and conclusion were provided in the light of theoretical and empirical findings.

Authors: Amna Zaujatul - , Aflah Ruhul
Published: December 2021

“Pidie Kriet” diartikan sebagai “Pidie pelit”. “Pidie kriet” merupakan suatu istilah yang melekat pada masyarakat Pidie, Aceh, Indonesia. Istilah tersebut masih berkembang hingga saat ini terutama di masyarakat Pidie, dimana stereotip tersebut berpengaruh bagi individu karena diasosikan seseorang yang berasal dari pidie diasosikan dengan stereotip dengan orang yang pelit. Hal ini tentunya akan memengaruhi perilaku altruisme dari individu tersebut. penelitian ini bertujuan untuk mengetahui hubungan antara stereotip “Pidie Kriet” dengan perilaku altruism, yang dilakukan terhadap 120 mahasiswa Pidie yang dipilih dengan menggunakan teknik sampling insidental. Hasil analisis menunjukkan terdapat hubungan negatif dan signifikan antara stereotip “Pidie Kriet” dengan perilaku altruism (p=0,014, r=0,227).  Hal ini dapat diartikan semakin tinggi stereotype pidie kriet dalam diri individu, maka semakin rendah perilaku altruismenya, dan juga sebaliknya. Hasil penelitian juga menunjukkan pada umumnya subjek memiliki tingkat perilaku altruisme yang tinggi dan stereotip “pidie kriet” yang rendah dalam dirinya. Dengan demikian, dapat dikatakan bahwa stereotip "Pidie Kriet" tidak terlalu memengaruhi perilaku altruisme mahasiswa Pidie tersebut.

International student mobility has over the past 10-15 years become an increasingly, more students from  across  the  world  are  able  to  participate  in  higher  education  abroad,  especially  those  from countries with  rapidly growing economies in Asian country  (i.e  Malaysia,  Indonesia, etc).  The  high  educational ranking  of  Malaysia    is  appealing  to  many Acehnese  students  including  to  study  in  Malaysia.  Studying  abroad  can  be  a challenge  having  to  adapt  and  adjust  oneself  to  a  whole  new  environment,  culture,  language, education system, lifestyle, and new friends. This study aims to investigate  the  levels  of  life satisfaction among Acehnese university students in Malaysia male and female. T-test analysis has performed to analyze the mean life satisfaction between male and female students. The result of this study reveals there was no significant difference in life satisfaction across gender. Further discussions are displayed in full view of this study.

Authors:   Gaidar Institute, Zamnius Alexey , Polbin Andrey ,   RANEPA,   Gaidar Institute
Published: December 2021

This paper provides an econometric analysis of the labor supply function of married women in Russia based on data from RLMS HSE and methodology from the work (Heckman, MaCurdy, 1980), in which decisions about entering the labor market and the intensity of work are made within a dynamic optimization problem. It is shown that the husband’s leisure and the number of children living in the household have a negative effect on the woman’s hours worked. The estimate of the Frisch elasticity of labor supply with respect to wages lies near 0.16.
Biodiversidad en cifras: avances en el conocimiento de especies en Costa Rica
Authors: Tania Bermúdez Rojas  , Vilma Obando Acuña
Published: December 2021

Para conservar y utilizar sosteniblemente la biodiversidad es fundamental conocerla, por ello se presentan los datos en cifras de algunos grupos taxonómicos de Costa Rica. La información fue recopilada, analizada y sistematizada en talleres, consulta a especialistas y revisión de publicaciones. Se presenta la información de forma integrada y sencilla, comparando las cifras del 2014 con el 2019 como actualización de los siguientes grupos taxonómicos: insectos, hongos, líquenes, plantas, peces, anfibios, reptiles, aves y mamíferos. Además, se mencionan los principales vacíos de información. Entre los principales resultados observamos que para el 2019 aumentó el número en la mayoría de los grupos de vertebrados, siendo los peces los de mayor incremento; para anfibios, reptiles, aves y mamíferos, el aumento fue menor debido a las revisiones taxonómicas que permitió el ingreso, pero también la eliminación de algunos registros.  El número de insectos, así como los artrópodos están en revisión. El número de plantas y hongos disminuyó, por la rectificación taxonómica de los dos grupos. Sin embargo, separando hongos de líquenes, este último presenta un incremento significativo. La información generada es fundamental para comenzar a generar datos serios, confiables y actualizados sobre nuestra biodiversidad.
Los agroecosistemas y su influencia en el desarrollo de adaptaciones conductuales en los animales silvestres: generalidades y un ejemplo en la provincia de Cartago, Costa Rica
Authors: Luis Mario Calderón Soto
Published: December 2021

La agricultura estimula el desarrollo económico en comunidades como Sabanillas, en Jiménez, Cartago. Sin embargo, la actividad también permite el crecimiento de la frontera agrícola y la disminución del hábitat para los animales silvestres de la región. Algunos animales han cambiado sus hábitos para aprovechar los recursos en este nuevo entorno, favoreciendo el desarrollo de adaptaciones conductuales y estableciendo agroecosistemas. No obstante, la agricultura tiene un impacto negativo en las poblaciones de depredadores que tienden a moverse mucho para encontrar alimento, pues es un obstáculo entre ellos y sus presas. El uso de tecnología para analizar, editar y crear mapas digitales por medio de imágenes satelitales y la fotografía de la vida silvestre, permiten conocer la distribución de los cultivos con respecto a las áreas de bosque y su influencia en los animales como insumo para futuros proyectos de conservación.
Magyar női teniszezők elégedettségvizsgálata és a sportág életpályamodellként való megvalósítása az infokommunikáció fejlődésének tükrében
Authors: Kincses Gábor , Ormos Mihály , Bartha Zsolt
Published: December 2021

A nemzetközi sportot hosszú évtizedeken keresztül hagyományosan a nyugati nemzetek uralták. A tenisz népszerűsége emelkedett, a társadalmi elit arisztokratikus szórakozásából a középosztály sportjává vált. Ezzel párhuzamosan a sportágban
megjelenő lehetőségek is megnőttek, mára milliárdos üzlet lett. A tenisz világszerte az egyik legsikeresebb női sport, a női teniszezők a legjobban fizetett sportolók közé tartoznak. A volt szocialista országok játékosai egyre nagyobb szerepet vállalnak a profi sportággá fejlődött globális teniszben. A tanulmány leírja a jelenség okait, középpontba állítva a már visszavonult és a ma is aktív elit magyar teniszező nőket. A kutatást a már visszavonult (n1=27), illetve az aktív (n2=20) magyar elit teniszezőnők körében tettük meg. Az adatgyűjtést kérdőíves módszerrel végeztük. A statisztikai elemzés igazolja, hogy a női teniszezők sportteljesítményének és sportkultúrájának vizsgálatában a játékosok elégedettségét differenciált tényezők befolyásolják. A tanulmány egyik fő következtetése, hogy a teniszkarrier már életpályamodellként is funkcionál.

Not all traits are functional: the Panglossian paradigm
Authors: Salguero-Gómez Rob , Laughlin Daniel C
Published: December 2021

The popularity of trait-based approaches continues to rise despite
challenges in identifying strong links between traits and organism
performance. Here, we summarise evidence demonstrating that not all
traits appear to be functional, and discuss how life history theory and
demography can help elucidate which, how, where, and when traits gain
functionality
Tackling the opioid crisis - development of kappa-opioid receptor peptide agonists for safer analgesic therapy
Authors: Lohman Rink-Jan , Tupally Karnaker Reddy , Kandale Ajit , Cabot Peter , Parekh Harendra
Published: December 2021

The kappa opioid receptor (KOPr) has exceptional potential as an
analgesic target, seemingly devoid of the many peripheral side-effects
of Mu receptors. Kappa-selective, small molecule pharmaceutical agents
have been developed, but centrally mediated side effects have the
limited their clinical translation. Here, we modify an active endogenous
Dynorphin peptide with the aim of improving drug-likeness and developing
safer KOPr agonists for clinical use. Using rational, iterative design
and modern peptide chemistry, we developed a series of potent, selective
and metabolically stable peptides from Dynorphin 1-7. Peptides were
assessed for cAMP-modulation against Kappa, Mu and Delta opioid
receptors, metabolic stability, KOPr specificity and binding, and
interrogated for in vitro desensitisation and pERK signalling
capability. Finally, lead peptides were evaluated for efficacy in
Freund’s complete adjuvant rat model of inflammatory nociception. A
library of 70 peptides was synthesised and assessed for pharmacological
and metabolic stability factors. At least 10 peptide candidates showed
low nanomolar activity (˂50 nM) in a cAMP assay, specificity for KORr,
and plasma half-life >60 min, with 6 candidates also stable
in trypsin. None of the selected peptides showed pERK activity, with a
bias towards cAMP signalling. In vivo, KA305 and KA311 showed
anti-nociception opioid receptor-specific activity comparable to
morphine and U50 844. These highly potent and metabolically stable
peptides are promising opioid analgesic leads for clinical translation.
Since they are biased peptide KOPr agonists, it is plausible they lack
many of the most significant side effects, such as tolerance, addiction,
sedation and euphoria/dysphoria, common to opioid analgesics.

Published: December 2021

A rodovia Transamazônica teve ampla repercussão na imprensa nacional quando foi inaugurada na década de 1970. Passados cinquenta anos, considerando que a estrada segue inacabada, indaga-se quais representações estão presentes no imaginário social sobre ela. O objetivo deste artigo é identificar a percepção que se tem construído sobre a Transamazônica, utilizando a metodologia da análise de discurso. Foram selecionados reportagens e textos jornalísticos de quatro veículos da grande imprensa nacional, entre 1970 e 2020. Foram destacados os seguintes marcadores: desenvolvimento, esperança, integração e devastação. Concluímos que a percepção sobre a rodovia muda com o tempo, evidenciando as contradições nos conceitos que expressam a trajetória da estrada.
