Published: March 2020

A novel severe acute respiratory syndrome coronavirus (SARS-CoV-2) was identified from respiratory illness patients in Wuhan, Hubei Province, China, which has recently emerged as a serious threat to the world public health. Hower, no approved drugs have been found to effectively inhibit the virus. Since it has been reported that the HIV-1 protease inhibitors can be used as anti-SARS drugs by tegarting SARS-CoV 3CLpro, we choose six approved anti-HIV-1 drugs to investigate their binding interactions between 3CLpro, and to evaluate their potential to become clinical drugs for the new coronavirus pneumonia (COVID19) caused by SARS-CoV-2 infection. The molecular docking results indicate that, the 3CLpro of SARS-CoV-2 has a higher binding affinity for all the studied inhibitors than its SARS homologue. Two docking complexes (indinavir and darunavir) with high docking scores were futher subjected to MM-PBSA binding free energy calculations to detail the molecular interactions between these two proteinase inhibitors and the 3CLpro. Our results show that darunavir has the best binding affinity with SARS-CoV-2 and SARS-CoV 3CLpro among all inhibitors, indicating it has the potential to become an anti-COVID-19 clinical drug. The likely reason behind the increased binding affinity of HIV-1 protease inhibitors toward SARS-CoV2 3CLpro than that of SARS-CoV were investigated by MD simulations. Our study provides insight into the possible role of structural flexibility during interactions between 3CLpro and inhibitors, and sheds light on the structure-based design of anti-COVID-19 drugs targeting the SARS-CoV-2 3CLpro.
A Formulation Protocol with Pyridine to Enable DNP-SENS on Reactive Surface Sites: Case Study with Olefin Polymerization and Metathesis Catalysts
Authors: Yakimov Alexander , Mance D , Searles Keith , Copéret Christophe
Published: March 2020

Dynamic nuclear polarization surface-enhanced NMR spectroscopy (DNP-SENS) has emerged as a powerful characterization tool in material chemistry and heterogeneous catalysis by dramatically increasing, by up to two orders of magnitude, the NMR signals associated with surface sites. DNP-SENS mostly relies on using exogenous polarizing agents (PAs) – typically di-nitroxyl radicals, to boost the NMR signals, that may interact with the surface or even react with highly reactive surface sites, thus leading to loss/quenching of DNP enhancements. Herein, we describe the development of a DNP-SENS formulation that allows us to broaden the application of DNP-SENS to samples containing highly reactive surface sites, namely a Ziegler-Natta propylene polymerization catalyst, a sulfated zirconia-supported metallocene and a silica-supported cationic Mo alkylidene. The protocol consists of adsorbing pyridine prior to the impregnation of the DNP formulation (TEKPol/TCE). The addition of pyridine does not only preserve the PAs and thereby restore the DNP enhancement, but it also allows probing the presence of Lewis acid and Brønsted acid surface sites that are often present on these catalysts.
Molecular Docking Study of Novel COVID-19 Protease with Low Risk Terpenoides Compounds of Plants
Authors: Shaghaghi Neda
Published: March 2020

Background :Due to the reported high ability of virulence of COVID_19 in recent months, several studies have been conducted to discover and introduce COVID_19 antiviral drugs. The results of numerous studies have shown that protease inhibitors and compounds, which make up the major part of plant derivatives, especially terpenoids, can therefore be very effective in controlling virus-induced infection. The aim of this research is the bioinformatical study of COVID_19 inhibition by terpenoids of plant origin. Materials and Methods: This is a descriptive-analytic study. In the present study , the structure of terpene comounds and COVID_19 protease was received from the databases such as PubChem and Protein Data Bank (PDB). After that, molecular docking was performed by MVD(molegro virtual docker) software. Results: The results are identified to have inhibitory activities against novel COVID-19 protease. Of these compounds, Ginkgolide A has a stronger bond and high affinity with protease Conclusion: Finally, with due attention to the high effectiveness function of terpenoids, we can conclude that these compounds may be considered as effectire COVID_19 antiprotease drugs
Structural Contributions to Autocatalysis and Asymmetric Amplification in the Soai Reaction
Authors: Athavale Soumitra , Simon Adam , Houk Kendall N , Denmark Scott
Published: March 2020

Diisopropylzinc alkylation of pyrimidine aldehydes – the Soai reaction, with its astonishing attribute of amplifying asymmetric autocatalysis, occupies a unique position in organic chemistry and stands as an eminent challenge for mechanistic elucidation. A new paradigm of ‘mixed catalyst substrate’ experiments with pyrimidine and pyridine systems allows a disconnection of catalysis from autocatalysis, providing insights into the role played by reactant and alkoxide structure. The alkynyl substituent favorably tunes catalyst solubility, aggregation and conformation while modulating substrate reactivity and selectivity. The alkyl groups and the heteroaromatic core play further complementary roles in catalyst aggregation and substrate binding. In the study of these structure activity relationships, novel pyridine substrates demonstrating amplifying autocatalysis were identified. Comparison of three autocatalytic systems representing a continuum of nitrogen Lewis basicity strength suggests how the strength of N-Zn binding events is a predominant contributor towards the rate of autocatalytic progression.

Published: March 2020

The arrows depicting electron movement and the bond-making and breaking events are the maps that guide student instruction in organic chemistry curricula. For students, the pathways represented by electron pushing formalism (EPF) can be tough to navigate. For instructors, providing formative feedback to students to support their learning of the EPF arrow system is difficult to provide in a timely manner. The Mechanisms app (“Mechanisms”) was developed as a method for students to explore the electron movement of organic chemistry through a touch screen interface of a smart phone or tablet and do so within a game-like experience. In this paper the pedagogical content of the Mechanisms app (“Mechanisms”) is described along with studies of students’ use of the app to understand whether the open-ended experience to construct understanding of EPF is valuable as a formative assessment method. Presented in this paper are the results of Mechanisms use by analysis of a multi-institution anonymous student survey, with a usability study of organic chemistry students, and with three case studies detailing the use of the app in college classrooms.
Computational Analysis of Electron Transfer Kinetics for CO2 Reduction with Organic Photoredox Catalysts
Authors: Kron Kareesa , Gomez Samantha , Cave Robert , Mallikarjun Sharada Shaama
Published: March 2020

We present a fundamental description of the electron transfer (ET) step from substituted oligo(p-phenylene) (OPP) radical anions to CO2, with the larger goal of assessing the viability of underexplored, organic photoredox routes for utilization of anthropogenic CO2. This work varies the electrophilicity of para-substituents to OPP and probes the dependence of rate coefficients and interfragment interactions on the substituent Hammett parameter, σp, using constrained density functional theory (CDFT) and energy decomposition analysis (EDA). Large electronic coupling elements across substituents indicate an adiabatic electron transfer process for reactants at contact. As one might intuitively expect, free energy changes dominate trends in ET rate coefficients in most cases, and rates increase with substituent electron-donating ability. However, we observe an unexpected dip in rate coefficients for the most electron- donating groups, due to the combined impact of flattening free energies and a steep increase in reorganization energies. Our analysis shows that flattening OPP LUMO levels lower the marginal increase in free energy with decreasing σp. Reorganization energies do not exhibit a direct dependence on σp. They are higher for substituents containing lone pairs of electrons since substituent orientation varies with OPP charge. EDA reveals that interfragment orbital relaxation, or charge transfer interaction, plays a critical role in stabilizing the vertically excited charge transfer state. Subsequent relaxation to the final state geometry lowers charge transfer stabilization. A concurrent increase in long-range electrostatic interactions is observed, which are more favorable for electron-withdrawing substituents. Our study therefore suggests that while a wide range of ET rates are observed, there is an upper limit to rate enhancements achievable by tuning substituent electrophilicity.

A Bimodal Approach for the Discovery of a View of the Implementation Platform of Legacy Object-Oriented Systems under Modernization Process
Authors: Abdelmalek Hamza , Chénard Gino , Khriss Ismaïl , Jakimi Abdeslam
Published: March 2020

Organizations are highly dependent on their software in carrying out their daily activities. Unfortunately, the repeated changes that are applied to these systems make their evolution difficult. This evolution may be necessary to maintain the software, replace or upgrade it. In the case of complex and poorly documented legacy systems, modernization is the only feasible solution to achieving the evolution goals. The OMG (Object Management Group) consortium created the Architecture-Driven Modernization (ADM) initiative to cope with the challenges of modernization. This initiative proposes, among other things, modernization through model-driven engineering (MDE). In this context, the modernization of a legacy system, not developed in an MDE environment, begins with its migration towards this type of environment. This migration raises the problem of finding the models necessary for the use of MDE representing this system.

In this paper, we present a new bimodal approach to ADM modernization by enabling automatic and interactive modes to discover a view of the implementation platform of a legacy object-oriented system. Also, we present the key ideas of the algorithms behind this discovery process. Finally, we describe our prototype tool that implements our approach. This tool has been validated on several systems written in C# and Java languages.
La “discriminación de género” en la jurisprudencia de la Corte Interamericana de Derechos Humanos
Authors: La Barbera MaríaCaterina , Wences Isabel
Published: March 2020

Este artículo analiza la jurisprudencia de la Corte Interamericana de Derechos Humanos en materia de discriminación de género. En la primera parte examinamos la polisemia de la categoría género y distinguimos tres enfoques: el de las mujeres como grupo desaventajado (enfoque de mujeres); el que pone el acento en la estructura social discriminatoria (enfoque de género); y el que se dirige a la estructura social compleja que interactúa con otros factores de discriminación (enfoque de la interseccionalidad). La segunda parte está dedicada al análisis de tres casos emblemáticos: Campo Algodonero, Atala Riffo y Gonzales Lluy. Exploramos qué dimensiones subyacen a la identificación de la violación de derechos humanos y sus causas, por un lado, y a las medidas de reparación y no repetición, por el otro. El objetivo es destacar los avances de la jurisprudencia interamericana en materia de discriminación estructural de género y proponer posibles desarrollos futuros.

Retóricas de la antidemocracia. Notas sobre la crisis del poder público y de la emancipación
Authors: Attili Antonella
Published: March 2020

Objetivo del ensayo es poner de relieve en qué modo y por qué en distintos contextos, neo-populistas, neoliberales o neoconservadores, está presente de manera llamativa una misma postura anti-democrática. Por eso pregunta en qué sentido y por qué el “neopopulismo” no es democrático, qué es “neo-populismo”. Además, si es lo mismo que “anti-política” o qué significa ésta y cómo explicar su relación con el neopopulismo. Reflexionando sobre qué es propio de la “democracia” moderna y qué es “democrático”, asimismo sobre por qué es autoritaria una democracia populista, intenta aclarar las razones de tal mezcla y empalme entre neopopulismo y anti-política. El significado válido de los términos mencionados ayuda a perfilar la especificidad de nuevo populismo, y a pensar en la gravedad de los retos que su anti-política plantea para la democracia y para las políticas públicas necesarias a la emancipación humana.
Tensiones entre libertad y democracia en el pensamiento de Philip Pettit
Authors: Diab Fernanda
Published: March 2020

La democracia contestataria implica un modelo de par- ticipación ciudadana que ofrece un potencial político limitado para garantizar y promover la no dominación como un ideal comunitario. En este artículo se sostiene que el problema no tiene que ver tanto con el diseño institucional sino con las tensiones entre este modelo de democracia y la noción de libertad que lo pretende orientar normativamente. La libertad como no dominación es un tipo de libertad negativa y como tal se mantiene indiferente a los fines que el sujeto persigue, por ello no permite justificar motivaciones que trasciendan el interés particular. Por esta razón la disputación resulta ser un mecanismo de control de las decisiones públicas que falla en su principal objetivo: la defensa de la libertad en un sentido republicano.

Telecommunication ecosystems: Special features of management and interaction
Authors: Kobylko Alexander
Published: March 2020

The article explores the current situation in the telecommunications industry. The current analysis is based on the dual nature of the telecom operator, which can be regarded as an independent ecosystem company and as an infrastructure basis for implementing the model by companies engaged in other areas of the economy. Diversification of services leads to the formation of ecosystems of hightech companies. The methodological framework of the study includes theoretical principles of the ecosystem approach and the theory of management of complex systems. The research methods are deduction, comparison and classification. In the course of the analysis of the telecommunications market, we find that an ecosystem is a complex socio-economic whole consisting of sets of harmoniously functioning blocks. Each ecosystem forms its own industry distinguished from every other. The ecosystem emerges on the basis of the technological platform created by the company. The ecosystem is not built around the company as a legal entity, but precisely around its brand. In order to win the telecom operator’s communication channels, ecosystems interact and unify through partnership or parasitic integration. These integration processes may indirectly indicate that a non-telecommunication company applies the ecosystem concept. The interpenetration of two or more ecosystems can lead to their merger in the future. These particularities show that it is impossible to categorize ecosystem as an unambiguously micro- or mesoeconomic component. Ecosystem management should be based not on the traditional principles of company management, but on a combination of management projects, which are unique, rather than routine, solutions in the form of regulation and assistance in attaining the set goals. The obtained results are of theoretical importance for performing further studies on ecosystem formations in today’s economy. In practical terms, the research results can be useful for the management of companies belonging to various ecosystems to justify the formats of effective business models and development strategies

Published: March 2020

Land utilization under oil palm plantation is constrained by the condition of low light intensities. Modification of the microclimate through the use of reflective mulch, as a reflector, will increase its ability to reflect the land surface radiation under the tree stand. This modification may suitable for intercropping system between soybean and oil palm. The study aimed to determine the effect of microclimate modification, using reflective mulch, under the stand of oil palm, and to evaluate its effect on soybean productivity. The research was conducted at PTPN-VIII Cimarga Banten using a nested random design with two factors and three replications each. The first factor is the oil palm age, which consists of: (i) control (open land), (ii) 4 years, (iii) 5 years, and (iv) 8 years age of oil palm. The second factor is the reflective mulch, as a solar radiation reflector, which consists of three levels: (i) without mulch (control), (ii) inorganic reflective mulch/silver black plastic mulch, and (iii) organic reflective mulch/dried oil palm leaves. The application of inorganic and organic reflective mulch increased the distribution of reflected land surface radiation (59%-157%), reduced the soil temperature fluctuation (0.30C-1.20C), and maintained soil water content (45.2%-45.8%). An increased of plant growth rates (56%-86%), relative growth rates (16%-21%), and seed weight production per plant (74.8%-86.2%) also reported, as well as the reduction of the etiolation ratio (9.6%-12.5%). The use of organic and inorganic reflective mulches can improve the microclimate and increase the production of soybean under intercopping system with oil palm.

Published: March 2020

Padi merupakan tanaman pangan yang paling banyak dikonsumsi oleh penduduk Indonesia. Produksi padi di Indonesia belum dapat memenuhi kebutuhan penduduknya, sehingga impor masih menjadi solusi utama. Kabupaten Jember merupakan salah satu kabupaten penghasil padi. Banyak varietas yang ditanam untuk mendapatkan produktivtas yang tinggi khususnya di Kecamatan Mayang, namun tidak semua kondisi tanah dan manajemen lahan akan mendapatkan hasil produksi padi secara optimal, karena kondisi lahan yang berbeda-beda. Unsur Nitrogen (N) adalah unsur hara makro yang sangat penting dalam mendukung pertumbuhan dan perkembangan tanaman padi. Kelebihan dan kekurangan unsur N berpengaruh terhadap tingkat efisiensi dan hasil produksi tanaman padi. Pengembangan budidaya padi di Jember khususnya Kecamatan Mayang perlu adanya simulasi hasil produksi padi bedasarkan pemupukan N dan kondisi lahan sehingga dapat dilihat potensi lahan untuk mengembangkan padi dan dapat dijadikan referensi untuk rekomendasi pemupukan N. Cropsyst adalah program komputer yang berfungsi untuk menganalisis produktivitas berdasarkan kondisi dan manajemen lahan. Input data tanah, iklim/lokasi, manajemen lahan dikalibrasikan dengan pertumbuhan tanaman serta dilakukan validasi. Simulasi dilakukan pada 10 petani sampel dan 6 petani pembanding. Hasil simulasi menunjukkan bahwa Cropsyst dapat digunakan dalam simulasi padi berdasarkan input nitrogen di Kecamatan Mayang karena menghasilkan nilai EF sebesar 0.93 dan RMSE sebesar -47.97. Setiap penambahan pupuk oleh petani sampel akan meningkatkan hasil panen padi. Pak Leha tidak dianjurkan untuk menambahkan N karena respon tanaman padi sudah mencapai 100%. Untuk mencapai hasil padi yang optimal dan efisien maka petani harus memberikan pupuk N sesuai dengan kebutuhan tanaman yaitu ketika respon tanaman mencapai 90% dari maksimal.

External evaluation in Roald Dahl’s The BFG
Authors: Deborah Joanna
Published: March 2020

There have been several significant changes in children’s literature in the past few decades; one of them is the change in the narative style. Roald Dahl is one of the most prominent authors of children’s literature that displays this particular change in his works. Dahl is known to utilize a creative narrative style in his works, and this is also seen in one of his children’s novels discussed in this research: The BFG (1982). This research thus aims at analysing one part of the narrative structure called external evaluation which shows the function of narrator in the story as well as the effects of the use of such narrative style on children as the target readers. Using Labov’s theory of narative structure and Genette’s theory of narratology, the results of the analysis shows that Dahl utilizes the function of narrator in the external evaluations to help children as his target readers to get a better understanding of the story as well as to build a close connection with them, resulting in the more enjoyable reading experience for the children.
Self-perceived communication competence and communication apprehension: A study of Indonesian college students
Authors: Subekti Adaninggar Septi
Published: March 2020

Considering the important role of Individual Differences (IDs) factors in variations in the ultimate success of learners learning second language (L2, this study investigated Indonesian college students’ two ID components, self-perceived communication competence (SPCC) and their communication apprehension (CA), in English as L2. Several rationales become the basis of the present study. Despite the importance of learners’ SPCC in L2 learning as suggested by several empirical studies outside Indonesia, there have not been any specific study investigating learners’ SPCC in the Indonesian context despite the country being the home of one of the largest number of L2 speakers of English in the world. As a seminal study in the context, the study using quantitative methods enables generalisation which could pave a way for further studies in the field in the Indonesian context. A total of 276 non-English major college students participated in the study in a survey using probability random sampling. Using descriptive statistics in SPSS 21, the study found that learners had medium level of SPCC and medium level of CA. Through correlation formula, the study also found that there was moderate significant association between learners’ SPCC and their CA. Through regression analysis, it was found that their SPCC could predict 23% of variance in their CA. The findings urge teachers to provide as many learning opportunities as possible in enjoyable learning environment to increase learners’ perception of their capability, in turn boosting their confidence to speak in English. Based on the findings and several limitations of the study, several suggestions of future studies are presented.
Infusing Islamic-related content through Trivia Cards: Research & development in ESP classroom
Authors: Farah Rafika Rabba
Published: March 2020

English learning has now largely been driven by global socioeconomics. Thus, English for Specific Purposes is likely taught at tertiary level education in Asia. Especially, in Indonesia, where Muslim is the major population, teaching English to students majoring in Islamic Studies must be carefully planned. Experts have discussed widely that English language has its association to Western civilization and Christian value. Therefore, this present research aims at developing Trivia Cards which infuse Islamic elements to teach English for Islamic Studies for students majoring in Islamic discipline at one private Islamic university in Indonesia. Research and Development (R&D) was implemented in the study involving some procedures as follows: need analysis, product design, product validation, and revision. Results on need analysis comprised five important topics, they were Islamic manner (akhlak), oneness of God (tauhid), Islamic history, and hadith. Further, the experts highlighted that the media developed reached its validity criteria as it was scored 98.07% by media-language expert; and scored 88.6% by content expert. Furthermore, the study were 95% positively responded by the respondents with 45% strongly agreed and 50% agreed respectively; meanwhile only small portion stated his/her disagreement for 5% or as many of one respondent. Thus, this study has shed a light that Islamic content can provide a way for English teachers to teach English to students with Muslim background.
ANALISIS PEMIKIRAN MUSDAH MULIA TENTANG WALI NIKAH DAN RELEVANSINYA TERHADAP PEMBARUAN HUKUM KELUARGA DI INDONESIA

The discussion of marriage guardian is one of the pillars that must exist in a marriage, illegitimate marriage without the presence of a guardian. The Compilation of Islamic Law (KHI) as the law governing Muslim marriages in Indonesia requires guardians as a legal condition of marriage (articles 14 and 19). However, on the other hand, one of the Muslim intellectuals, Siti Musdah Mulia, stated an opposing idea, that guardians are not included in the pillars of marriage. The results showed that the Musdah Mulia thinking generally led to the typology of liberal Islamic thought. Specifically on the issue of the absence of guardians in marriage, Musdah's opinions are not too contrary to the text; Musdah's attention to gender places a substantial portion in establishing the law; and the Musdah idea is not only channeled in the form of thought alone but also poured into the form of a legal regulation draft (CLD-KHI) so that the law applies comprehensively and can be applied clearly and can achieve justice and social benefit in the midst of the people. Then based on this, a specific typology of Musdah Mulia's thought was obtained about the absence of guardians in the marriage harmony leading to progressive Islamic thought. And Musdah Mulia's ideas about the lack of marriage guardians have sufficient relevance to the renewal of Islamic family law in Indonesia.

Since the beginning of the archipelago, the archipelago has functioned as a cross-trade route for the West Asian, East Asian and South Asian regions. The arrival of Islam in the archipelago is full of debates, there are three main issues that historians debate. First, the place of origin of Islam. Second, the carriers. Third, the time of arrival. However, Islam has entered, grown and developed in the archipelago quite rapidly. Considering the arrival of Islam to the archipelago which at that time already had Hindu-Buddhist culture. So this is very encouraging because Islam is able to develop in the midst of the lives of people who already have strong and longstanding cultural roots. The arrival of Islam to the archipelago experienced various ways and dynamics, including trade, marriage, social culture, and so on. This causes the growth and development of Islam in this region has its own style. In addition, Ulama who came to the Nusantara region approached their people with an approach that tended to be gentle. In this case it is done with a philosophical approach to Sufism. This teaching is easily accepted and experiences rapid development in the midst of the Nusantara community so that Islam is more easily accepted. This paper uses a historical approach that emphasizes the aspects of time and chronology by using a heuristic approach, source criticism, synthesis and historiography which are characteristic of the final results of writing history.

TUBUH PEREMPUAN PADA CERITA RAKYAT JAWA TIMURAN: JAKA TARUB DAN ANDE-ANDE LUMUT
Authors: Iswara Tiara Widya
Published: March 2020

Cerita rakyat Jaka Tarub dan Ande-Ande Lumut merupakan cerita legendaris yang sudah tidak asing lagi bagi masyarakat Indonesia terutama masyarakat Jawa Timuran. Cerita tersebut sama-sama memiliki inti cerita pencarian pasangan hidup oleh seorang laki-laki, selain itu juga menceritakan bagaimana seorang perempuan pada masa tersebut menerima dominasi bias gender tanpa ada paksaan dan tanpa disadari mereka mematuhinya atau karena sebuah alasan patriarki. Penelitian ini bertujuan untuk mengungkapkan peran tubuh perempuan yang terjadi pada tokoh utama perempuan. Terdapat dua hal yang akan menjadi fokus penelitian ini adalah (1)bagaimana representasi perempuan dalam kedua cerita tersebut? dan (2)bagaimana peran tubuh perempuan itu terjadi? Oleh karena itu, penelitian ini disusun menggunakan perspektif feminisme menurut Lois Tyson (2006). Hasil penelitian ini memperlihatkan perempuan menerima objektivikasi tubuh melalui berbagai cara. Dalam cerita Jaka Tarub, Nawang Wulan ketika menjadi istri Jaka Tarub ia mulai terbiasa menjalankan tugasnya sebagai wanita Jawa dalam hal domestifikasi konvensional namun diakhir cerita posisi Jaka Tarub menggeser domestistifikasi perempuan dalam hal parenting. Berbeda dengan cerita Ande-Ande Lumut terlihat para Klenting berjuang dengan cara mampu menjaga kesuciannya untuk dapat dipilih sebagai istri Panji Asmarabangun. Kesucian adalah sebuah keharusan yang dimiliki perempuan bagi laki-laki yang memilihnya.
