Solid electrolytes are crucial for next generation solid state batteries and Na3PS4 is one of the most promising Na+ conductors for such applications. In this contribution, we present a detailed investigation of the evolution in structure and dynamics of Na3PS4 under the effect of temperature in the range 30 < T < 600 °C through combined experimental-computational analysis. Although x ray Bragg diffraction experiments indicate a second order phase transition from the tetragonal ground state (α, P-421c) to the cubic polymorph (β, I-43m), pair distribution function analysis in real space and Raman spectroscopy indicate remnants of tetragonal character in the range 250 < T < 500 °C which we attribute to dynamic local tetragonal distortions. The first order phase transition to the mesophasic high temperature polymorph (γ, Fddd) is associated with a sharp volume increase and the onset of liquid like diffusive dynamics for sodium-cations (translative) and thiophosphate-polyanions (rotational) evident by inelastic neutron- and Raman- spectroscopies, as well as pair-distribution function and molecular dynamics. These results shed light on the rich polymorphism in Na3PS4 and are relevant for a host of high performance materials deriving from the Na3PS4 structural archetype.

Published: March 2021

Transition metal complexes with β-diketonate and diamine ligands are valuable precursors for the chemical vapor deposition (CVD) of metal oxide nanomaterials, but the metal-ligand bond dissociation mechanism on the growth surface is not clarified yet. We address this question by Density Functional Theory (DFT) and ab initio molecular dynamics (AIMD) in combination with the Bluemoon (BM) statistical sampling approach. AIMD simulations of the Zn β-diketonate-diamine complex Zn(hfa)2TMEDA (hfa = 1,1,1,5,5,5-hexafluoro-2,4-pentanedionate; TMEDA = N,N,N’,N’-tetramethylethylenediamine) show that rolling diffusion of this precursor at 500 K on a hydroxylated silica slab leads to an octahedral-to-square pyramidal rearrangement of its molecular geometry. The free energy profile of the octahedral-to-square pyramidal conversion indicates that the process barrier (5.8 kcal/mol) is of the order of magnitude of the thermal energy at the operating temperature. The formation of hydrogen bonds with surface hydroxyls plays a key role in aiding the dissociation of a Zn-O bond. In the square-pyramidal complex, the Zn center has a free coordination position, which might promote the interaction with incoming reagents on the deposition surface. These results provide a valuable atomistic insight on the molecule-to-material conversion process which, in perspective, might help to tailor by design the first nucleation stages of the target ZnO-based nanostructures.
SARS-CoV-2 VOCs Immune Evasion from Previously Elicited Neutralizing Antibodies Is Mainly Driven by Lower Cross-Reactivity Due to Spike RBD Electrostatic Surface Changes

Published: March 2021

Leveraging structural data and computer modelling techniques, we investigated the variation in the binding free-energy (𝛥𝛥𝐺) profile of VOCs and VOIs SARS-CoV-2 lineages with hACE2 and with a dataset of known human nAbs. In agreement with the available experimental data, our results show only a marginal impact of VOC RBD amino acid changes to hACE2 affinity. On the other hand, we found that VOCs RBDs have a significant unfavorable 𝛥𝛥𝐺 to nAbs that can be related to changes in the electrostatic potential surface profiles, hence identifying the molecular and thermodynamical components behind SARS-CoV-2 antibody evasion. In addition, our data suggests that a close attention should be given to lineage P.3, as it likely holds a high spreading potential in a human population with rising immunity. In summary, the current observed higher transmission of SARS-CoV-2 VOCs is likely associated with a partial or complete failure of the antibody recognition and neutralization in individuals previously exposed to SARS-CoV-2 non-VOC variants. These results have key implications on i. the basic understanding of VOCs emergence and maintenance; ii. on the rational design of antibody-based therapeutics; iii. vaccine efficacy and updates; and iv. may be exploited to rapidly screen immune scape worrisome lineages.
Influence of Glass Composition on the Luminescence Mechanisms of CdSe Quantum Dot-Doped Glasses
Authors: Li Wenke , Zhao Xiujian , Liu Chao , Coudert François-Xavier
Published: March 2021

In this work, we characterized the electronic structure of CdSe quantum dots embedded in a series of x Na2O, (1–x) SiO2 glass matrices (x = 0, 0.25, 0.33 and 0.5). We analyzed the impact of the glass matrix composition on both the atomic structure of the quantum dot (QD) and the QD/glass interface, as well as the luminescence mechanisms, using density functional theory (DFT) calculations. The increase of Na2O content in the glass matrices was found to promote the formation of Cd–O and Se–Na interfacial bonds, and disrupting the Cd–Se bonds network. In particular, we show that the glass composition directly affects the nature of the highest occupied molecular orbitals (HOMO). According to the atomic structure, the band gap distribution and the density of states calculation, we find that there is significant reconstruction of the QD, and that the picture sometimes proposed of a “pristine QD” surrounded by glass is not realistic. The introduction of CdSe QD significantly decreased the bandgap of the glass compared to pristine glasses, and the interfacial bonds greatly contributed to the frontier orbitals without forming midgap states. We propose a new energy diagram, quite different from the traditional model, to explain the luminescence of CdSe quantum dot- doped glasses, originating from the intrinsic emission of this hybrid system {QD + glass}. These results improve our understanding of the luminescence of CdSe quantum dot-doped glasses, explaining the reason for the poor quantum efficiency and broad emission linewidth compared with their colloidal counterparts.

Published: March 2021

La eficiencia del uso de nitrógeno en la agricultura es muy baja, provocando problemas ambientales y baja productividad de los cultivos, por lo que conocer la distribución espacial y temporal de variables biofísicas que estimen su crecimiento, como la fracción de cobertura vegetal (FCV), y el contenido de nitrógeno del dosel (CND) aportará información valiosa para mejorar esta condición. El uso de imágenes satelitales de libre acceso, como las imágenes del satélite Sentinel-2 (S‑2), puede facilitar esta tarea. Con base en lo anterior, se realizó un estudio en seis parcelas de maíz, cultivadas por productores de la zona de Texcoco de Mora, Estado de México, cuyo primer objetivo fue investigar la relación entre índices espectrales, estimados a partir de la reflectancia, medida con un radiómetro multiespectral a nivel de superficie y de imágenes S-2; con la FCV, estimada mediante fotografías digitales a través de la aplicación para celulares Canopeo. El segundo objetivo fue obtener un modelo lineal para estimar el CND a partir del análisis de diferentes índices espectrales. Se generaron dos modelos para estimar la FCV, a partir de la información radiométrica a nivel de superficie, la validación de estos arrojó un valor alto de R2 = 0.92 y un CME = 7.3% entre datos de FCV medidos y estimados; sin embargo, en el caso de los datos estimados con imágenes S-2 se obtuvieron valores más bajos de R2 = 0.67 y CME = 17.6%, lo cual se atribuyó a un posible efecto de la atmósfera, ya que el periodo de estudio coincidió con la temporada de lluvias. Finalmente, en el caso del CND, los mejores resultados se obtuvieron con el modelo generado a partir del ClGreen, con el cual se obtuvo un R2 de 0.91 y un CME de 0.63 g m-2, al comparar el CND medido con relación al estimado.

Forest is one of renewable land properties which endowed with numerous resources that are valuable to man. The quality of the environment is constantly losing its status due to increase in population size in most countries of the world. The general objective of this study was to assess the effect of population dynamics on forest cover in West Hararghe Zone in general and Daro Labu Wereda (DLW) in particular. Systematic random sampling technique was used to select the target population of this study whose total number was 364 households from four kebeles of DLW. Questionnaire, interview, FGD and satellite imagery used as data gathering tools for this study. The quantitative data of this study were analyzed using descriptive statistics and the qualitative data were discussed and interpreted through narration. As the result in this study a mixed method was used. This study is triangulation study in its design. The study was found out that population dynamics had contributed a lot to deforestation of the wereda under the study through agricultural land expansion, settlement, fuel wood gathering and illegal tree cutting. Thus due to  population growth, lack of alternative livelihood approach, ruthless profit making, lack of economic transformation human encroachment and lack of alternative sources of energy. Population growth had contributed greatly to forest deforestation especially as it affected the forest covers. The major findings were observed that expansion for cultivated and settlement LULC classes rapidly increased from1973 to 2013 on the contrary forest and shrub lands decreased in DLW due to population dynamics and human encroachment in the forest cover. Therefore, there is an urgent need with government for the various stakeholders in environmental resource management to provide mechanism that can prevent the forest cover from further reduction in the study area.

KESEIMBANGAN PEKERJAAN DAN KEHIDUPAN PRIBADI SERTA GAYA KERJA BARU, BAGAIMANA DAMPAKNYA TERHADAP STRES KERJA?
Authors: Syarifah Tsalitsa Haura , Etikariena Arum
Published: March 2021

Studi terhadap 154 orang karyawan kantor pusat PT Bank Syariah X bertujuan untuk mengetahui pengaruh keseimbangan kehidupan-kerja dan gaya kerja baru terhadap stres kerja. Hasil analisis regresi pada masing-masing variabel prediktor menunjukkan bahwa keseimbangan kehidupan-kerja memiliki pengaruh yang negatif dan signifikan terhadap stres kerja (β = -0,56, p<0,01). Namun, variabel gaya kerja baru ditemukan tidak berpengaruh secara signifikan terhadap stres kerja (β = 0,37, p>0,05). Selanjutnya, hasil analisis regresi berganda menemukan bahwa keseimbangan kehidupan-kerja dan gaya kerja baru secara bersama-sama berpengaruh signifikan terhadap stress kerja, F(2, 151) = 33,98, R=0,56, p<0,01, R2=31%). Temuan ini menunjukkan bahwa 31% proporsi varians stres kerja dapat dijelaskan oleh keseimbangan kehidupan-kerja, sedangkan 69% sisanya dipengaruhi oleh faktor lain yang tidak diukur dalam penelitian ini. Oleh sebab itu, dapat dikatakan bahwa keseimbangan kehidupan-kerja merupakan variabel prediktor yang berpengaruh lebih kuat terhadap stres kerja dibandingkan dengan gaya kerja baru.

De outro, inquirimos sobre o potencial de repensar pressupostos da disciplina a partir de um evento recente transcorrido na Amazônia: o Encontro Amazônia Centro do Mundo. Para responder à primeira pergunta, sistematizamos produções acadêmicas em RI apresentadas/publicadas nos três últimos Encontros Nacionais da Associação Brasileira de Relações Internacionais (ABRI) e nas revistas Carta Internacional, Contexto Internacional e Revista Brasileira de Política Internacional. Organizamos os resultados obtidos em termos de: (1) alocação nas Áreas Temáticas da ABRI; (2) divisões temáticas em categorias por nós identificadas; (3) produções por região geográfica do Brasil e (4) divisões temáticas por região geográfica. A partir do que observamos sobre o estado da arte em estudos de Amazônia nas RI no Brasil, propomos uma “outra inscrição” da Amazônia na disciplina a partir do Encontro Amazônia Centro do Mundo (EACM) e das perspectivas e reivindicações dos “povos da floresta” ali articuladas. Sob essa base, apresentamos uma breve reflexão crítica sobre os conceitos de “poder” e “resistência” nas RI, e concluímos apontando o potencial do EACM para se pensar nas potencialidades de uma “cosmopolítica da Amazônia”.

Este artigo tem como objetivo discutir a construção de grandes projetos hidrelétricos na Amazônia brasileira, a partir das estratégias de despolitização utilizadas para o seu tratamento técnico-científico e o processo de contestação de conhecimentos com base na mobilização social contrária a esses projetos. A hidreletricidade tem sido vista nos últimos anos como uma alternativa limpa e renovável de fornecimento de energia frente às mudanças climáticas, justificando a sua retomada na Bacia Amazônica e omitindo seus impactos socioambientais. As estratégias de despolitização visam mobilizar conhecimentos para que as infraestruturas hidroelétricas sejam compreendidas a partir de uma abordagem técnica, que compactua com a ideia de projetos infalíveis da engenharia moderna que ignora riscos associados à sua construção e operação. Estes projetos afetam de modo desigual os grupos sociais, sendo os mais impactados aqueles que são forçados a se deslocarem e tem seus modos de vida alterados. Assim, são analisadas as estratégias de despolitização empregadas para a construção das usinas de Santo Antônio, Jirau e Belo Monte, bem como a mobilização social contrária aos projetos como meio de repolitização da temática das grandes hidrelétricas, demonstrando a contestação de conhecimentos nesta arena.
Interseccionalidade e colonialidade como chaves interpretativas: reflexões amazônicas sobre direitos humanos
Authors: Ribeiro Igor Veloso , Fernandes Estevão Rafael
Published: March 2021

Buscando responder à questão “a interseccionalidade é uma opção decolonial?” refletimos, de modo crítico, sobre a adequação dessas duas chaves interpretativas para a compreensão dos Direitos Humanos em povos das Américas. A teoria da interseccionalidade propõe uma análise dos entrecruzamentos dos marcadores sociais gênero/raça/classe. Por outro lado, decolonialidade apresenta um contexto histórico, político e social, a partir do qual compreende-se feixes hierárquicos como heranças coloniais. Essas chaves interpretativas trazem, em suas reflexões, formas de compreender a violação seletiva de direitos humanos e desconstruir os sistemas de hierarquização e poder. Buscamos aqui apontar suas limitações e potencialidades nesse sentido.

Keadaan penanggulangan darurat bencana dengan adanya Kejadian Luar Biasa COVID-19 ini memaksa guru dan warga sekolah untuk menyesuaikan kegiatan belajar mengajar sesuai dengan kondisi siswa dan orang tua di rumah. Hal ini menyebabkan, kualitas BDR di setiap keluarga berbeda-beda, karena tidak adanya rubrik penilaian proses dan belajar siswa yang standar untuk setiap orang tua untuk mencapai proses belajar yang bermakna selama masa darurat COVID-19. Tujuan kegiatan yaitu meningkatkan pengetahuan dan keterampilan guru SD dalam pembuatan rubrik penilaian proses dan hasil belajar siswa yang terstandarisasi sebagai panduan/pedoman bagi orang tua menjalankan kebijakan BDR.  Kegiatan pendampingan guru ini menggunakan metode social learning dengan empat fase yakni fase perhatian, fase retensi, fase reproduksi, dan fase motivasi. Sasaran kegiatan adalah Gugus SD Se-Kota Bengkulu. Melalui rubrik ini dapat mewujudkan prinsip penilaian yang transparan, objektif, adil, efisien, dan akuntabel. Berdasarkan hasil analisis data dan pembahasan dapat ditarik kesimpulan sebagai berikut: (1) peningkatan pengetahuan guru paling tinggi pada aspek implementasi penugasan siswa saat BDR secara terintegrasi. (2) peningkatan pengetahuan rubrik pada aspek ketepatan jawaban dan kemunculan gagasan lain/baru. (3) peningkatan keterampilan paling tinggi pada aspek menentukan tema penugasan/proyek mingguan.

Floods become major concerns in most gobe regions due to socio-economic and environmental consequences caused by these phenomena in recent decades. Most Algerian cities are exposed to flood risks and suffered from its consequences. The purpose of this paper is the spatialization of flood hazard in the city of Chemora (Algeria) by hydraulic modelling in a GIS environment whose objective is prevention, which requires a set of hydrological and hydraulic informations in order to achieve a comprehensive and effective management.
Philo and Josephus on the Fidelity of Judeans
Authors: Eyl Jennifer
Published: March 2021

The first century sees a substantial rise in the frequency with which Greek speaking authors discuss pistis (here, understood as fidelity, trust, confidence, proof). The authors who use pistis the most include Philo, Paul, and Josephus. This suggests that while many people are thinking about fidelity, ethnic Judeans are thinking about it disproportionately. This essay focuses on two such authors, Philo and Josephus. I argue that both Judeans claim fidelity to be a foundational national-ethnic characteristic, from the patriarchs to their own day. Furthermore, the article argues that this image of enduring Judean fidelity can be better understood within the context of living under the colonizing power of Rome – a principate that is equally preoccupied with fidelity (fides).

Objetive: to evaluate the adherence of health professionals to interventions by the clinical pharmacist service in the prevention of venous thromboembolism in a teaching hospital. Methods: This is a retrospective study in which, through data collection and analysis statistics (considering p <0.05 as the level of significance), pharmaceutical therapies related to drug prescription related to prophylaxis of venous thromboembolism (following the protocol in force at the institution) for patients admitted to a teaching hospital in Minas Gerais from December 2019 to August 2020.. The level of acceptance of clinical pharmacy interventions regarding the need to prescribe prophylactic anticoagulants, change in anticoagulation dosage, prescription of two or more anticoagulants and the lack of risk classification was evaluated for the development of venous thromboembolism for inpatients. Results: in the nine-month period, 62 pharmaceutical interventions were performed before the clinical staff, with 82.25% adherence: need for prescription of anticoagulants (82.75%); change in anticoagulation dosage (80%) and prescription of two or more anticoagulants (100%). In the same period, 2070 interventions (100%) with the nursing team were identified regarding the lack of risk classification for the development of venous thromboembolism for patients admitted via the RM Saude system. Conclusion: the evaluation allowed to identify the importance of the clinical pharmacist in the prevention of thromboembolic events for patients admitted to a hospital.
