Published: April 2021

Density functional theory with the BPW91 functional and def2-TZVP basis sets was used to investigate the geometric structures of VB5−/0 clusters. By using the bee colony algorithm, 300 initial structures are created for the studied cluster. The geometry optimizations at the BPW91/def2-SVP level result in 18 low-lying isomers in quartet states for the anionic cluster. The results at the BPW91/def2-TZVP level show relative energies and vibrational frequencies for different spin states of 7 isomers of the anionic clusters and 6 isomers of the neutral cluster. It is found that the most stable isomers are A-VB5−/0 with non-planar pentagonal structure. The adiabatic detachment energy of the anionic cluster and the ionization energy of the neutral cluster are 1.93 and 7.36 eV.

Objetivo: Analisar a reação de lideranças de entidades esportivas aos primeiros projetos de lei acerca de atividades de aventura no Brasil com relação a ações do turismo.Metodologia: Estudo qualitativo interpretativo de inspiração etnográfica e historiográfica, que teve como método a análise documental, sobretudo de textos governamentais, institucionais e da mídia especializada.Originalidade/relevância: Temática recente e atual, a ocorrência de acidentes em práticas de aventura e sua evitação demanda embasamento para o desenvolvimento do campo e mediação de conflitos entre seus agentes. Este artigo contribui com a originalidade da discussão sobre a tensão entre lideranças de comunidades de esportistas e empresários do turismo acerca das propostas de projetos de lei.Principais Resultados: A regulamentação dos esportes de aventura no Brasil via projetos de lei federais, estaduais e municipais não se materializou, mas gerou amplo debate entre mercado, Estado e sociedade civil durante sua tramitação. Os resultados demonstram que, alguns atletas ou esportistas autônomos de aventura não estiveram de acordo com as políticas públicas propostas no país e buscaram juridicamente a garantia constitucional de acesso gratuito aos ambientes naturais e liberdade de gestão do risco na prática como forma de lazer.Contribuições teóricas metodológicas: Os resultados contribuem teoricamente para demonstrar a complexidade das relações entre as lideranças do esporte e turismo e propostas de políticas públicas para práticas de aventura, e que certos perfis de esportistas não aceitaram a caracterização de atividades de aventura como turismo. Metodologicamente, esse estudo reforça que não se pode tratar documentos oficiais como referências bibliográficas e sim como fontes de dados a serem problematizados.
Presupuestos terapéuticos y pseudomorfosis en los trabajos Martyrs (2014) y Mary (2016) de Bill Viola
Authors: Aguirre-Martínez Guillermo 
Published: April 2021

En 2014 Bill Viola completa su trabajo Martyrs, un encargo realizado por la Catedral de san Pablo, en Londres. Dos años después quedará concluida Mary, obra que complementa a Martyrs y que encuentra su ubicación, en esa misma catedral, en el extremo opuesto del ábside. Tomando como eje vertebrador la significación de los cuatro elementos (agua, tierra, aire, fuego) y el fenómeno de pseudomorfosis habitual en los trabajos de Viola, exploraremos los fundamentos de un arte terapéutico. La emergencia de contenidos profundos del imaginario permite la revitalización psicosomática del sujeto.
In 2014 Bill Viola finished his work Martyrs, requested by Saint Paul’s Cathedral, in London. Two years later the American artist ended another work, Mary, that complements Martyrs. Mary is located, also in Saint Paul’s Cathedral, on the opposite side of the apse. Since the meaning of the four elements (water, earth, air and fire) and the idea of pseudomorphosis that normally structures Bill Viola’s works, we will explore the premises of a therapeutic art. The emergence of deep sediments buried in our imaginary, allows the psychosomatic revitalisation of the individual.

Victoria o muerte: Música para los últimos momentos de El Álamo en el cine
Authors: Justo Estebaranz Ángel , Pérez García Lucía 
Published: April 2021

La defensa y batalla de El Álamo en 1836 supone uno de los grandes acontecimientos de la Historia americana, hito fundacional sobre el que el cine se interesó desde sus primeros momentos, y que ha conocido diversas interpretaciones a lo largo de un siglo (1911-2004). Los momentos más dramáticos fueron las horas previas a la batalla final, tras trece días de asedio de las tropas del general Santa Anna a los texanos, y la propia batalla. El tratamiento musical que los diferentes compositores de la partitura de cada película han dado a estos momentos ha variado en función de diversos factores. En este artículo analizamos la música de las escenas relativas al día previo a la batalla y al asalto final, abordando especialmente el toque de degüello empleado por cada uno, su importancia en el conjunto de la partitura, sus posibles referentes, su estructura y el carácter del tema. Para ello diseñamos unas tablas de análisis de contenido categorial, que nos permiten comparar las seis películas estudiadas y llegar a las conclusiones.
The defense and the battle of The Alamo in 1836 is one of the greatest events of American History. Film writers, directors and producers were interested in it since the early days, so there are several adaptations from 1911 to 2004. The most dramatic moments were the hours before the battle after thirteen days of siege of the Santa Anna’s troops, and the final assault. According to different factors, each film composer has written a personal version of the music for these scenes. In this paper we analyze the musical treatment applied to the scenes of the previous day and of final assault, highlighting the different versions of the deguello, its importance inside the score, its sources, structure and character. For to do this, we use tables of categorical content which let us to compare the six films we studied and to reach the conclusions.

Published: April 2021

Background
Hepatocellular carcinoma (HCC) is considered to be a malignant tumor with a high incidence and a high mortality. Accurate prognostic models are urgently needed. The present study was aimed at screening the critical genes for prognosis of HCC.

Methods
The GSE25097, GSE14520, GSE36376 and GSE76427 datasets were obtained from Gene Expression Omnibus (GEO). We used GEO2R to screen differentially expressed genes (DEGs). A protein-protein interaction network of the DEGs was constructed by Cytoscape in order to find hub genes by module analysis. The Metascape was performed to discover biological functions and pathway enrichment of DEGs. MCODE components were calculated to construct a module complex of DEGs. Then, gene set enrichment analysis (GSEA) was used for gene enrichment analysis. ONCOMINE was employed to assess the mRNA expression levels of key genes in HCC, and the survival analysis was conducted using the array from The Cancer Genome Atlas (TCGA) of HCC. Then, the LASSO Cox regression model was performed to establish and identify the prognostic gene signature. We validated the prognostic value of the gene signature in the TCGA cohort.

Results
We screened out 10 hub genes which were all up-regulated in HCC tissue. They mainly enrich in mitotic cell cycle process. The GSEA results showed that these data sets had good enrichment score and significance in the cell cycle pathway. Each candidate gene may be an indicator of prognostic factors in the development of HCC. However, hub genes expression was weekly associated with overall survival in HCC patients. LASSO Cox regression analysis validated a five-gene signature (including CDC20, CCNB2, NCAPG, ASPM and NUSAP1). These results suggest that five-gene signature model may provide clues for clinical prognostic biomarker of HCC.

Published: April 2021

Abstract1D materials have attracted significant research interest due to their unique quantum confinement effects and edge‐related properties. Atomically thin 1D nanoribbons are particularly interesting because it is a valuable platform with the physical limits of both thickness and width. Here, a catalyst‐free growth method is developed and the growth of Bi2O2Se nanostructures with tunable dimensionality is achieved. Significantly, Bi2O2Se nanoribbons with a thickness down to 0.65 nm, corresponding to a monolayer, are successfully grown for the first time. Electrical and optoelectronic measurements show that Bi2O2Se nanoribbons possess decent performance in terms of mobility, on/off ratio, and photoresponsivity, suggesting their promise for devices. This work not only reports a new method for the growth of atomically thin nanoribbons but also provides a platform to study properties and applications of such nanoribbon materials at a thickness limit.

Published: April 2021

AbstractMultiN‐heterocyclic carbene(NHC)‐modified iridium catalysts were employed in the β‐alkylation of alcohols; dimerization of primary alcohols (Guerbet reaction), cross‐coupling of secondary and primary alcohols, and intramolecular cyclization of alcohols. Mechanistic studies of Guerbet reaction, including kinetic experiments, mass analysis, and density functional theory (DFT) calculation, were employed to explain the fast reaction promoted by bimetallic catalysts, and the dramatic reactivity increase of monometallic catalysts at the late stage of the reaction.magnified image

Published: April 2021

AbstractJudd–Ofelt (JO) theory explains the optical properties of trivalent lanthanides using only three intensity parameters. The JO parametrization is a complicated procedure of absorption spectra analysis, especially cumbersome for powders and non‐transparent materials. For the Pr3+ activated materials, the procedure is additionally complicated due to strong interaction of low‐lying Pr3+ 4f5d energy levels with the 4f levels. Here, the straightforward JO parametrization method that uses the emission spectrum and the excited state lifetime of the Pr3+ 3P0 level which does not require any fitting procedure are shown. In addition, the theory and software for calculations of JO parameters from Pr3+ emission are explained. The method requirements are low‐temperature photoluminescence measurements of Pr3+ introduced in low phonon energy hosts with a relatively high lying 4f5d energy level. The method is demonstrated on emissions of YF3:Pr3+ and LaF3:Pr3+ powders.
Extraction of allelochemicals from germinated wheat seeds and their inhibitory effects on cucumber
Authors: Bai Jingwen , Bai Xuedong , Yang Yu , Tao Bo 
Published: April 2021

AbstractMicrowave‐assisted extraction (MAE) of allelochemicals from germinated wheat (Triticum aestivum L.) seeds was optimized by using response surface methodology. Under the optimal conditions (temperature 70 °C, power 283 W, liquid/solid ratio 17 L kg–1 and time 20.0 min), the inhibitory rate of allelochemicals on cucumber (Cucumis sativus L.) seeds germination was 64.21±1.99%. Three main allelochemicals including p‐Hydroxybenzoic acid, 3‐methoxy‐4‐hydroxycinnamic acid, and 3,5‐dimethoxy‐4‐hydroxybenzoic acid were identified by liquid chromatography–tandem mass spectrometry (LC‐MS/MS) analysis. These allelochemicals significantly inhibited the growth of cucumber seeding and root. Furthermore, malondialdehyde (MDA) content increased and root vitality and amylase activity decreased after the treatment of allelochemicals. Glutathione (GSH) content, glutathione peroxidase (GSH‐Px), and glutathione transferase activities rose first and then fell with the allelochemicals concentration increased. These results suggested that the extract from germinated wheat seeds could inhibit the growth of cucumber by affecting the physiological and biochemical processes in cucumber.

AbstractSleep‐disordered breathing (SDB) is common in patients with skeletal dysplasias. The aim of our study was to analyze SDB and respiratory management in children with rare skeletal dysplasias. We performed a retrospective analysis of patients with spondyloepiphyseal dysplasia congenita (SEDC), metatropic dysplasia (MD), spondyloepimetaphyseal dysplasia (SEMD), acrodysostosis (ADO), geleophysic dysplasia (GD), acromicric dysplasia (AD), and spondylocostal dysplasia (SCD) between April 2014 and October 2020. Polygraphic data, clinical management, and patients' outcome were analyzed. Thirty‐one patients were included (8 SEDC, 3 MD, 4 SEMD, 1 ADO, 4 GD, 3 AD, and 8 SCD). Sixteen patients had obstructive sleep apnea (OSA): 11 patients (2 with SEDC, 1 with SEMD, 1 with ADO, 1 with GD, 2 with AD, and 4 with SCD) had mild OSA, 2 (1 SEMD and 1 GD) had moderate OSA, and 3 (1 SEDC, 1 MD, 1 SEMD) had severe OSA. Adenotonsillectomy was performed in one patient with SCD and mild OSA, and at a later age in two other patients with ADO and AD. The two patients with moderate OSA were treated with noninvasive ventilation (NIV) because of nocturnal hypoxemia. The three patients with severe OSA were treated with adenotonsillectomy (1 SEDC), adeno‐turbinectomy and continuous positive airway pressure (CPAP; 1 MD), and with NIV (1 SEMD) because of nocturnal hypoventilation. OSA and/or alveolar hypoventilation is common in patients with skeletal dysplasias, underlining the importance of systematic screening for SDB. CPAP and NIV are effective treatments for OSA and nocturnal hypoventilation/hypoxemia.

Published: April 2021

AbstractMethyl oleate, a kind of vegetable oil derivatives, was used as the raw material to synthesize novel polyols containing nitrogen and phosphorus (PNP) by three steps: amidaion, epoxidation, and ring‐opening reaction. The structure of the ensuing PNP was characterized by gel permeation chromatography, Fourier transform infrared spectroscopy, and nuclear magnetic resonance spectroscopy. Then, polyurethane films were prepared by mixing the resulting polyols (PNP) and poly‐(tetra methylene glycol) with isophorone diisocyanate in different proportions. After that, the thermostability of polyurethane films was investigated by limiting oxygen index (LOI), thermogravimetry, and cone calorimeter test. Similarly, mechanical property of polyurethane films was studied by tensile test. The results showed that as the amount of PNP increased, the tensile strength of polyurethane films increased from 2.0 to 13.5 MPa, the LOI values of polyurethane films went up from 20.1% to 25.5%. Moreover, the initial decomposition temperature of polyurethane films improved from 280 to 312°C and the total heat release drooped from 32.2 to 21.7 kW/m2without adding any other flame retardant. Therefore, it was observed that the polyurethane films have superior thermal stability and mechanical property and appear suitable for a wide range of applications.

Authors: Khera Rajiv , Ransom Pat , Guttridge Mark , Speth Thomas F. 
Published: April 2021

AbstractWhen choosing a treatment technology for nitrate or perchlorate removal, drinking water utilities overwhelmingly choose ion exchange. However, of late, biological treatment and point‐of‐use systems have received a great deal of attention. This article utilizes several new U.S. Environmental Protection Agency models to estimate the cost of nitrate and perchlorate treatment for small drinking water systems. The analysis here shows that, when comparing the three technologies for a typical set of design choices and drinking water quality conditions, the least‐cost option varies among the three depending on system size. This relationship varies with changes to the water quality and design factors such as, but not restricted to, influent nitrate and perchlorate concentrations, the choice of residual management options, and the presence of co‐contaminants and competing ions.Article Impact StatementSmall systems that struggle with nitrate and perchlorate contamination will benefit from this evaluation of treatment costs.
Orbitrap‐MS‐based untargeted metabolomics study on the therapeutic effect of colchicine on myocardial infarction
Authors: Wen Wei , Zhang Zhongxiao , Jiang Bing , Hao Ying 
Published: April 2021

AbstractMyocardial infarction (MI) is one of the most common causes of death worldwide. A metabolomic approach based on an ultra‐high performance liquid chromatography–Orbitrap analytical method was established to analyze the metabolites and to investigate the therapeutic mechanism of colchicine. Forty‐six biomarkers were significantly changed between the sham group and the MI group. Thirty‐five metabolites were increased and 11 were decreased in MI rats, and colchicine reversed all of them. Pathway analysis showed that the TCA cycle, alanine, aspartate and glutamate metabolism, glycerophospholipid metabolism, aminoacyl‐tRNA biosynthesis, glyoxylate and dicarboxylate metabolism and arginine biosynthesis were altered in the MI group. Ingenuity pathway function and network analysis showed that colchicine improved MI through regulation of cardiac β‐adrenergic signaling and cardiac hypertrophy signaling. The present study provided a useful approach for exploring the mechanism of MI and evaluating the efficacy of colchicine.
