Influência de erosões superficiais e trincas na segurança de barragens de rejeito
Authors: Morandini Thiago Luiz Coelho
Published: July 2020

O número crescente de rupturas de barragens de rejeito impõe avanços constantes nas técnicas de avaliação de segurança destas estruturas. A análise em portfólio é considerada a técnica de avaliação mais ágil na rotina de garantia de segurança; entretanto sua aplicação é muitas vezes subjetiva e dependente da expertise do avaliador. Neste sentido, este artigo apresenta os resultados da avaliação de influência de erosões e trincas na segurança de barragens de rejeito objetivando a diminuição de subjetividade em análises em portfólio. Foram simuladas 5 barragens tipo, tanto alteadas a jusante quanto a montante, com variação de parâmetros de resistência do aterro e do rejeito, totalizando um universo de dados de 90 barragens. Também foram simuladas erosões superficiais e trincas de pequena, média e grande magnitudes, assim como o efeito combinado dessas anomalias. Os resultados demonstraram a perda da margem de segurança para erosões de 3,5%, 7,0% e 10,5% e para trincas de 8%, 16% e 24%. Os resultados para as simulações combinadas revelaram que a superposição dos efeitos pode ser aproximada pela soma simples da perda de margem de segurança das anomalias averiguadas. Conclui-se que a técnica de levantamento de anomalias em campo para avaliação do impacto sobre a segurança de barragens de rejeito é válida, indicando que é possível aplicar as análises em portfólio com menor subjetividade do avaliador. Conclui-se também que esta técnica pode ser expandida e contribuir para avaliações frequentes e garantia de segurança de barragens de rejeito.

Linear-Scaling Systematic Molecular Fragmentation Approach for High-Level Coupled-Cluster Methods: Coupled-Cluster Meets Macromolecules
Authors: Bozkaya Uğur , Ermiş Betül
Published: July 2020

The coupled-cluster (CC) singles and doubles with perturbative triples [CCSD(T)] method is frequently referred to as the “gold standard" of modern computational chemistry. However, the high computational cost of CCSD(T) [O(N7)], where N is the number of basis functions, limits its applications to small-sized chemical systems. To address this problem, efficient implementations of linear-scaling coupled-cluster methods, which employ the systematic molecular fragmentation (SMF) approach, are reported. In this study: (1) to achieve exact linear-scaling and to obtain a pure ab inito approach, we revise the handling of nonbonded interactions in the SMF approach (2) a new fragmentation algorithm, which yields smaller sized fragments; hence, better fits high-level CC methods is introduced (3) the new SMF approach is integrated with the high-level CC methods, denoted by LSSMF-CC, for the first time. Performances of the LSSMF-CC approaches, such as LSSMF-CCSD(T), are compared with their canonical versions for a set of alkane molecules, CnH2n+2 (n=6–10), which includes 142 molecules. Our results demonstrate that the LSSMF approach introduces negligible errors compared with the canonical methods, mean absolute errors (MAEs) are between 0.20–0.59 kcal mol-1 for LSSMF-CCSD(T). To further assess the accuracy of the LSSMF-CCSD(T) approach, we also consider several polyethylene (PE) models. For the PE set, the error of LSSMF-CCSD(T)/cc-pVDZ with respect to the experimental polymerization energies per unit are between 0.08–0.63 kcal/mol. To illustrate the efficiency and applicability of the LSSMF-CCSD(T) approach, we consider an alkane molecule with 10004 atoms. For this molecule, the LSSMF-CCSD(T)/cc-pVTZ energy computation on a Linux cluster with 100 nodes, 4 cores and 5 GB of memory are provided to each node, is performed just in ∼ 24 hours. As far as we know, this computation is an application of the CCSD(T) method on the largest chemical system to date. Overall, we conclude that (1) the LSSMF-CCSD(T) method can be reliably used for large scale chemical systems, where the canonical methods are not computationally affordable (2) the LSSMF-CCSD(T) method is very promising for accurate computation of energies in macromolecular systems (3) we believe that our study is a significant milestone in developing CC methods for large-scale chemical systems.

The down-conversion of high energy light with a fluorescent material may provide sufficient emission intensity to invoke a measurable neurological response in optogentically-active neurons. This work describes the use of anthracene-containing copolymers for use as a fixed emission material in optogenetic electrophysiology to demonstrate the feasibility of this technique. An anthracene-modified methacrylate was synthesized and copolymerized with methyl methacrylate to produce glassy copolymers with physical properties like those of poly(methyl methacrylate) (PMMA). The fluorescence in both solution and solid states are like those of pure anthracene and overlap fully with the absorption spectrum of channelrhodpsin-2. Scintillation is observed but is weak compared to fluorescence. The copolymers were found to be non-toxic to neuronal cultures. Whole cell patching measured the voltage changes of neurons under UV-irradiation in the absence and presence of a copolymer film. Increased frequencies and amplitudes of electrical events were observed in the presence of the polymers.

Published: July 2020

Protein orientation in nanoparticle-protein conjugates plays a crucial role in binding to cell receptors and ultimately, defines their targeting efficiency. Therefore, understanding fundamental aspects of the role of protein orientation upon adsorption on the surface of nanoparticles (NPs) is vital for the development of clinically important protein-based nanomedicine. In this work, new insights on the effect of the different orientation of cytochrome c (cyt c) bound to gold nanoparticles (GNPs) using various ligands on its apoptotic activity is reported. Time-of-Flight Secondary-Ion Mass Spectrometry (ToF- SIMS), electrochemical and circular dichroism (CD) analyses are used to investigate the characteristics of cyt c orientation and structure on functionalized GNPs. These studies indicate that the orientation and position of the heme ring inside the cyt c structure can be altered by changing the surface chemistry on the NPs. A difference in the apoptosis inducing capability because of different orientation of cyt c bound to the GNPs is observed. These findings indicate that the biological activity of a protein can be modulated on the surface of NPs by varying its adsorption orientation. This study will impact on the rational design of new nanoscale biosensors, bioelectronics, and nanoparticle-protein based drugs.

Acute and subacute toxicity screening of novel entrants in the stream of polyherbal formulations opens new doors towards the scientific approach of establishing them in the clinical market. Toxicity profiling asserts the humongous pharmacological potential that the natural herbs hold and establishes their safety profile. To exemplify this statement, this study further deals with acute and subacute toxicity studies of an olive oil-based polyherbal combination (PHC). This combination has been developed with the view that it proves to be clinically effective in diabetic cardiomyopathy and neuropathy. However, until now, the acute and subacute toxicity studies have been done on the developed PHC, and experimentally effective dose combinations have been identified. The follow-up part of this research includes the screening of the PHC against specific in vivo screening models in its initial stages. This research paper strictly summarises the acute and subacute profile of the salubrious polyherbal combination. Three herbs with strong literature background were selected: Tinospora cordifolia, Withania somnifera and Boerrhavia diffusa; and their crude extracts were prepared. The reported ED50 values of each of these plants were selected and mixed in 5 different combinations and subjected to Acute Toxicity studies. It was followed by the 28-days subacute toxicity screening of 9 different combinations that were elucidated from the acute toxicity study results. The findings were supported with recovery group studies to conform to any late toxicity symptoms of the polyherbal combination. The findings of this study helped in reaching some pathbreaking conclusions on the polyherbal combination designed.

Published: July 2020

HIV continues to be a major global public health issue, having claimed more than 32 million lives so far. While great progress has been made in preventing and treating HIV, there is still much to do. A safe and cost-effective vaccine that prevents HIV infection is considered the best strategy for containing the epidemic. However; historically, the vaccine development for HIV prevention has been extremely difficult. Anti-Retroviral Therapy (ART) has improved the quality of life of Human immunodeficiency virus (HIV) patients worldwide. This reality suggests that continuing on HIV vaccine research, now we should also consider applying other short-term available prevention and treatment strategies to mitigate the effect of the epidemic.

The analysis and characterization of climate variability over a long five-year period proved fundamental to understanding the impacts of climate change and the vulnerability of ecosystem services in the South Kivu province in the Democratic Republic of Congo. Collection methods from surveys and literature reviews allowed us to conduct qualitative and quantitative analyses of climate change impacts and adaptation approaches based on ecosystem services. For data collection, we used surveys and inventories. The data were statistically analyzed, mainly with regression methods and arithmetic averages. The results of agro-pastoral, fisheries and water production highlight the strong influence of climate change through the decrease in products essential for local consumption. These results are confirmed by statistical analysis almost everywhere R² < 0.5 and p-value > 0.05 (except for vegetable production « p-value < 0.05», Cereal: R²= 0.54 and Legume:  R²= 0.74). The same results show us that the non-regulation of river regimes and the decrease in water production by the appropriate service as a result of precipitation and temperature variability data have led to unprecedented disruption due to negative effects on the ecosystem services analyzed.  The proposals of the ecosystem-based adaptation approaches as a solution and are important indicators that have assessed climate risks of ecosystem services combined with the poverty impacts of the population and its environment highly vulnerable to climate change.
THE EMERGENCE OF GAUDIYA VAISHNAVISM IN MANIPUR AND ITS IMPACT ON NAT SANKIRTANA
Authors: Manna Subhendu
Published: July 2020

The Gaudiya Vaishnavism that emerged with Shri Chaitanya in the fifteenth century continued even after his passing in the hands of his disciples and spread to far-away Manipur. Bhagyachandra – the King of Manipur along with his daughter Bimbabati Devi, visited Nabadwip and established a temple to Lord Govinda which stands till today in the village called Manipuri in Nabadwip. Therefore, the strand of Bengal’s Gaudiya Vaishnavism that Bhagyachandra brought to Manipur continues to flow through the cultural life of the Manipuri people even today, a prime example of which is Nat Sankirtana. The influence of Gaudiya Vaishnavism on Nat Sankirtana is unparalleled.

Este artigo analisa os mecanismos de controle do capital as ações de resistência e de disputa hegemônica presentes – com diversas limitações e contradições- na organização da produção da existência camponesa. Nesse sentido, a defesa da educação omnilateral em contraposição à educação unilateral se apresenta enquanto tarefa fundamental no sentido da construção de uma sociedade que não se paute pelos ditames do capital. As reflexões apresentadas neste texto se fundamentam no materialismo histórico e dialético que parte das condições e determinações materiais da produção da vida as quais, por sua vez, determinam em última instância a consciência - não de forma mecânica ou imediata - e juntamente, à relação dialética ser humano- ser humano, ser humano-natureza, ser humano-mundo, onde a categoria central para pensar o real da vida material e imaterial é o trabalho.

Este artigo traz à cena uma reflexão de forma exploratória sobre os desafios postos aos professores, no que tange à reinvenção dos processos avaliativos de cursos de EaD, diante do momento vivenciado pela COVID 19. Para esse debate, parte-se do pressuposto de que a avaliação sempre constituiu um desafio para o professor, pois a ação de avaliar pressupõe escolhas, as quais, muitas vezes, estão enlaçadas pelas definições das políticas públicas. No momento atual, em que a pandemia alterou o ritmo das vidas das pessoas, a avaliação na educação a distância, que se realizava presencialmente teve alterações para atender às especificações determinadas pelo isolamento social. Nesse cenário, o repensar sobre a avaliação se impõe e a possibilidade de refletir sobre a temática, num processo de formação continuada que se inicia. A formação continuada dos professores se evidencia na construção da subjetividade individual e coletiva.

El artículo es producto de investigación en equipo con jóvenes investigadoras y monitoras. Se hizo con estudiantes de primer semestre, en el área de Introducción a la Ingeniería de la Facultad de Ingeniería Civil, en la Universidad Santo Tomás, seccional Tunja. Este aspecto permitió la evaluación de competencias humanas y profesionales. Se propuso como objetivo, hacer un diagnóstico sobre las competencias que se estudiaron trabajo en equipo, autonomía, experticia, solidaridad y pensamiento crítico. Se acompañó a cada estudiante para contribuir al desarrollo de cada competencia, a través de un proceso de atención y orientación en su desempeño académico y desarrollo integral en la asignatura. Se encontró que los estudiantes aprobaron la materia, con evidencias de construcción del conocimiento teórico-práctico, desarrollado por medio del método de proyectos. Éste es un método que se ha utilizado en la formación de ingenieros, pero que privilegia la parte disciplinar a diferencia de lo que se trabajó en la presente investigación con resultados halagadores en competencias humanas. Igualmente, se encontró una estrategia que permite la prevención y disminución del abandono/deserción de la asignatura y la carrera profesional.

Lettori di Marco Polo a Santa Maria Novella
Authors: Conte Maria
Published: July 2020

The aim of this paper is to propose a new and updated description of a manuscript named Conventi soppressi C.VII.1170, which hands down a Latin version of Marco Polo’s Milion made by Francesco Pipino of Bologna OP. The Conventi soppressi manuscript is a significant witness of the text for its antiquity, the elegance of its making, and the authority of its production. The codicological analysis allows to clarify numerous doubts (or to address several open questions) about the manufacture of the manuscript and the meaning of the iconography. Furthermore, it allows to discover new palaeographic elements that identify a rewriting intervention. Therefore, the set of features related to the making of the manuscript suggests an overview about the social and historical context of its production, where the consideration of a book as an object is related to its practical function.

Bu çalışmada, Bacillus thuringiensis var. kurstaki (Btk) içeren bir biyoinsektisitin (Delfin) predatör böcek Cryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae)’ye karşı doğrudan ve dolaylı etkileri incelenmiştir. Denemeler laboratuvar koşullarında yürütülmüş ve etkinlik IOBC değerlerine göre sınıflandırılmıştır. Predatör böcek, 28±1°C, 16:8 saat (aydınlık: karanlık) ve %60±5 bağıl nem iklim koşullarında patates filizleri üzerinde yetiştirilen Turunçgil unlubiti Planococcus citri Risso (Hemiptera: Pseudococcidae) kullanılmıştır. Doğrudan etki denemelerinde, Btk hem erginlere hem de 4. dönem C. montrouzieri larvalarına karşı sprey-tower ile uygulanmıştır. Uygulamadan 24 saat, 48 saat ve 10 gün (ergin), 20 gün (larva) sonra sağlıklı/hastalıklı böcekler sayılmıştır. Dolaylı etki denemelerinde, Btk-içeren biyoinsektisit petri kaplarında test edilmiştir. Kontrol petrilerine saf su uygulanmıştır. Çalışmadan elde edilen sonuçlar, Btk-içeren biyoinsektisitin, hem ergin hem de C. montrouzieri larvalarına karşı doğrudan ve dolaylı etkisinin olmadığını, yani çalışma boyunca ölüm gözlenmediğini göstermiştir (Zararsız: 1; IOBC). Bu sonuçlar, Btk'nin C. montrouzieri’nin uygulandığı narenciye bahçelerindeki IPM programlarında güvenle kullanılabileceğini göstermiştir.
