The effect of temperature in the range of 0–150 8C was studied for homoionic montmorillonite clays with Na and Csqq compensating ions in low hydration states. Both static and dynamic information concerning the interlayer ions and water moleculeswas obtained by Monte Carlo and molecular dynamics. Principal structural changes were limited to the water phase, markeddifference was o...

With the negative impact of COVID-19 on educational activities, face-to-face education was suspended at universities and distance replaced with it. The aim this study is to determine whether students learned some concepts related subject "radioactivity" taught by emergency remote (ERE) reveal students' opinions both ERE teaching ERE. To end, a qualitative conducted asking five open-ended questi...

A presente pesquisa mostra a percepção dos professores de química e biologia do município Itacoatiara-AM sobre o ensino remoto emergencial (ERE). Na busca entender ponto vista docentes no processo ensino-aprendizagem em tempos pandemia, coletou-se dados, via SurveyMonkey, utilizando questionamentos referente aos desafios enfrentados ERE. De acordo com os resultados obtidos, maioria consideraram...

Let R be an Artin algebra and e idempotent of R. Assume that Tor (Re, G) = 0 for any G ∈ Gproj eRe i sufficiently large. Necessary sufficient conditions are given the Schur functor Se to induce a triangle-equivalence ⅅdef(R) ≃ ⅅdef(eRe). Combining this with result Psaroudakis et al. (2014), we provide necessary singular equivalence ⅅsg(R) ⅅsg(eRe) restrict GprojR GprojeRe. Applying these triang...

XVII. mendeko krisiak azken hamarkadetan berrikusketa sakona jasan duen arren, urte askoan ikerketa ugariren iturburu izan zen. Ideia hau, Bigarren Mundu Gerra osteko Britainia Handiko historiografia marxistaren baitan zen sortua, feudalismoaren eta kapitalismoaren arteko trantsizioaren inguruko eztabaidaren testuinguruan. 1950eko hamarkadaren amaieratik, gero arreta handiagoa jarri zitzaien me...

Esta pesquisa bibliográfica tem por objetivo discutir as semelhanças e diferenças entre os conceitos de educação a distância (EaD), ensino remoto emergencial (ERE) outras novas denominações surgidas com adoção do ERE nas escolas básica no período pandêmico. Para isso, foram utilizados referenciais teóricos acerca da EaD (BRASIL, 1996; 2017; ARRUDA, 2020; JUNQUEIRA, PAIVA, TODOS PELA EDUCAÇÃO, 2...

In the post-genome era, the structures of protein domains have been published rapidly. Researches have also gained diversity of interests from the structure data, yet only few have concentrated on protein tertiary structure alignment while alignments focused on protein surfaces are even rarer. However, the surface structure of a protein binding motif should be deemed an important factor to dete...
