Published: August 2020

The aim of this study is to investigate the extraction of molybdenum from the spent HDS catalyst. The experiment was performed by using the pyro-hydrometallurgical process; calcination and leaching. The spent catalyst was calcined at different temperatures in order to investigate the effect of calcination temperature on the recovery of molybdenum in the subsequent process. Leaching of the calcined samples was subsequently performed by using the different concentrations of leaching reagent. The leaching was conducted by varying the concentration of NaCO3 of 20 g/L, 30 g/L and 40 g/L with a fixed leaching temperature of 90°C, a S/L ratio (weight of calcined sample/volume of leaching reagent) of 100 g/L and leaching time of 1 hrs. under the stirring condition at a speed of 250 rpm. It was found that carbon and sulfur contained in the spent HDS catalyst could be reduced by the calcination process and resulting in enhanced extraction efficiency of molybdenum. The extraction efficiency of molybdenum increased with increasing concentration of leaching reagent. At a certain concentration of leaching reagent, the extraction efficiency of the sample calcined at lower temperatures was higher than the sample which was subjected to calcination at a higher temperature.

Published: August 2020

A carboxymethylcellulose-based encapsulant system for the controlled release of nitrogen-phosphorus-potassium (NPK) fertilizer was synthesized using alginate as a stabilizer, and citric acid as a crosslinking agent. Fourier-transform infrared (FT-IR) spectroscopy, particle size analysis, zeta potential measurement, and scanning electron microscopy showed successful crosslinking, sufficient particle size and colloidal stability, as well as the topography of the formed particles. Fluorescence spectroscopy confirmed successful encapsulation of a model system, 8-anilino-1-napthalenesulfonic acid. Release behavior studies under various pH conditions showed that CMC/Alg NPK conformed to the standards of controlled release fertilizer with a maximum release rate of 50% over the span of 30 days.

Published: August 2020

Hydrogen energy has great potential to become one of the clean energies of the future. The current use of hydrogen gas as an energy source still has problems, namely in the distribution and storage system. One solution to overcome these problems is to use the adsorption method. Zeolite material is considered to be a good material to be used as a storage medium for hydrogen gas. Experimental research generally still requires a fairly high cost. Therefore, we need another method that can support it. In this research, the author used the Molecular Dynamics Simulation method. The variation of temperature used in this simulation is 77, 100, 150, 195, 273, and 293 K with a variation of pressure at each temperature is 1, 2, 4, 6, 8, and 10 bar. Our simulation results are then compared with the results of experimental research conducted by other researchers. At low pressure and high temperature, the results of our simulation are close to the results of experimental research. But at high pressure and low temperature, the results of our simulation are significantly different from the results of experimental research.

Background:

Osteoporosis and sarcopenia are important aspects of motor neuron disease (MND). Individuals with amyotrophic lateral sclerosis (MND-ALS) have an increased risk of falls and fractures. Currently, the standard of care does not involve a routine assessment of bone mineral density (BMD) and body composition in these patients. We aimed to assess BMD, bone mineral parameters and body composition in men with MND and compared them with healthy controls.

Methods:

Consecutive males between 50 and 80 years of age diagnosed as MND-ALS by revised El Escorial criteria and able to walk unassisted attending Neurology outpatient clinic were recruited into the study. Age, gender and body mass index (BMI) matched healthy controls were recruited from the local community. BMD and body composition were assessed by dual-energy x-ray absorptiometry (DXA). Bone mineral parameters and bone turnover markers (BTMs) were also assessed in them.

Results:

A total of 30 subjects with MND-ALS and 33 controls were recruited. The mean age (years) was 59.2 in cases and 61.2 in controls. The mean BMD (g/cm2) between the two groups was similar; however, BTMs were significantly higher in the MND group (P < 0.05). Subjects with MND-ALS had significantly lower mean appendicular lean mass (ALM) (19.9 versus 22.4 kg; P = 0.007) and ALM corrected for BMI than the healthy control group (0.858 versus 0.934 kg/kg/m2; P = 0.034). Sarcopenic obesity (Percentage fat mass >27% + ALM/BMI <0.786 kg/kg/m2) was more prevalent in MND-ALS compared to controls (44.5% versus 16.7%; P = 0.03).

Conclusion:

Although BMD was not significantly different between subjects with MND-ALS and healthy controls, BTMs were significantly higher in the MND group indicating a high bone turnover state. Sarcopenia and sarcopenic obesity were also more in MND-ALS group than controls. Routine assessment for bone health parameters and body composition indices may be included in management of the patients with MND.

As a crucial transcription factor for spermatogenesis, GATA-binding protein 4 (GATA4) plays important roles in the functioning of Sertoli and Leydig cells. Conditional knockout of GATA4 in mice results in age-dependent testicular atrophy and loss of fertility. However, whether GATA4 is associated with human azoospermia has not been reported. Herein, we analyzed the GATA4 gene by direct sequencing of samples obtained from 184 Chinese men with idiopathic nonobstructive azoospermia (NOA). We identified a missense mutation (c.191G>A, p.G64E), nine single-nucleotide polymorphisms (SNPs), and one rare variant (c.*84C>T) in the 3´ untranslated region (UTR). Functional studies demonstrated that the p.G64E mutation did not affect transactivation ability of GATA4 for spermatogenesis-related genes (claudin-11 and steroidogenic acute regulatory protein, Star), and the 3´ UTR rare variant c.*84C>T did not generate microRNA-binding sites to repress GATA4 expression. To our knowledge, this is thefirst report to investigate the association between GATA4 and azoospermia; our results indicate that mutations in GATA4 may not be pathogenic for NOA in Chinese men.

Published: August 2020

Abstract. We have developed in situ and flask sampling systems for airborne measurements of variations in the O2/N2 ratio at the part per million level. We have deployed these instruments on a series of aircraft campaigns to measure the distribution of atmospheric O2 from 0–14 km and 87° N to 85° S throughout the seasonal cycle. The NCAR airborne oxygen instrument (AO2) uses a vacuum ultraviolet (VUV) absorption detector for O2 and also includes an infrared CO2 sensor. The VUV detector has a precision in 5 seconds of ±1.25 per meg (1σ) δ(O2/N2), but thermal fractionation and motion effects increase this to ±2.5–4.0 per meg when sampling ambient air in flight. The NCAR/Scripps airborne flask sampler (Medusa) collects 32 cryogenically dried air samples per flight under actively controlled flow and pressure conditions. For in situ or flask O2 measurements, fractionation and surface effects can be important at the required high levels of relative precision. We describe our sampling and measurement techniques, and efforts to reduce potential biases. We also present a selection of observational results highlighting the individual and combined instrument performance. These include vertical profiles, O2 : CO2 correlations, and latitudinal cross sections reflecting the distinct influences of terrestrial photosynthesis, air-sea gas exchange, burning of various fuels, and stratospheric dynamics. When present, we have corrected the flask δ(O2/N2) measurements for fractionation during sampling or analysis, with the use of the concurrent δ(Ar/N2) measurements. We have also corrected the in situ δ(O2/N2) measurements for inlet fractionation and humidity effects by comparison to the corrected flask values. A comparison of Ar/N2-corrected Medusa flask δ(O2/N2) measurements to regional Scripps O2 Network station observations shows no systematic biases over 10 recent campaigns (+0.2 ± 8.2 per meg, mean and standard deviation, n = 86). For AO2, after resolving sample drying and inlet fractionation biases previously on the order of 10–100 per meg, independent AO2 δ(O2/N2) measurements over 6 more recent campaigns differ from coincident Medusa flask measurements by −0.3 ± 7.2 per meg (mean and standard deviation, n = 1361), with campaign-specific means ranging from −5 to +5 per meg.
Fire Weather Index: the skill provided by the European Centre for Medium-Range Weather Forecasts ensemble prediction system

Published: August 2020

Abstract. In the framework of the EU Copernicus programme, the European Centre for Medium-Range Weather Forecasts (ECMWF) on behalf of the Joint Research Centre (JRC) is forecasting daily fire weather indices using its medium-range ensemble prediction system. The use of weather forecasts in place of local observations can extend early warnings by up to 1–2 weeks, allowing for greater proactive coordination of resource-sharing and mobilization within and across countries. Using 1 year of pre-operational service in 2017 and the Fire Weather Index (FWI), here we assess the capability of the system globally and analyse in detail three major events in Chile, Portugal and California. The analysis shows that the skill provided by the ensemble forecast system extends to more than 10 d when compared to the use of mean climate, making a case for extending the forecast range to the sub-seasonal to seasonal timescale. However, accurate FWI prediction does not translate into accuracy in the forecast of fire activity globally. Indeed, when all fires detected in 2017 are considered, including agricultural- and human-induced burning, high FWI values only occur in 50 % of the cases and are limited to the Boreal regions. Nevertheless for very large events which were driven by weather conditions, FWI forecasts provide advance warning that could be instrumental in setting up management and containment strategies.

Abstract. Rain-on-snow (ROS) events can accelerate the surface ablation of sea ice, thus greatly influencing the ice-albedo feedback. However, the variability of ROS events over the Arctic Ocean is poorly understood due to limited historical station data in this region. In this study early melt season ROS events were investigated based on four widely-used reanalysis products (ERA-Interim, JRA-55, MERRA2 and ERA5) in conjunction with available observations at Arctic coastal stations. The performance of the reanalysis products in representing the timing of ROS events and the phase change of precipitation was assessed. Our results show that ERA-Interim better represents the onset date of ROS events in spring and ERA5 better represents the phase change of precipitation associated with ROS events. All reanalyses indicate that ROS event timing has shifted to earlier dates in recent decades (with maximum trends up to −4 to −6 days/decade in some regions in ERA-Interim), and that sea ice melt onset in the Pacific sector and most of the Eurasian marginal seas is correlated with this shift. There has been a clear transition from solid to liquid precipitation, leading to more ROS events in spring, although large discrepancies were found between different reanalysis products. In ERA5, the shift from solid to liquid precipitation phase during the early melt season has directly contributed to a reduction in spring snow depth on sea ice by more than −0.5 cm/decade averaged over the Arctic Ocean since 1980, with the largest contribution (about −2.0 cm/decade) in the Kara-Barents Seas and Canadian Arctic Archipelago.
Dyslexia in a Global Context: A Cross-Linguistic, Cross-Cultural Perspective
Authors: Maunsell Matthias
Published: August 2020

Dyslexia is a global issue. It encompasses a range of language and literacy cultures with many variations regarding definitions, diagnostic measures, regulations, policies, and support procedures for dyslexic students. Considerable progress has been made in the field of monolingual dyslexia, but now there is growing interest in the multilingual, multiethnic and multicultural world of dyslexia. Provision and supports are considered broader for multilingual learners than for those who are monolingual. With cross-cultural and cross-linguistic differences among students, teachers need to implement inclusive practices to ensure successful language and content learning in the classroom. Based on an extensive search of relevant literature, the purpose of this narrative review is to explore research on dyslexia from an international, cross-cultural, and cross-language perspective. The goal is also to highlight universal or unique characteristics, to emphasize the diversity of global interest, and to discuss the training needs of educators who must support culturally and linguistically diverse students with dyslexia.
Interdisciplinary Exploration Clarifying Barriers Hindering Minority Achievement
Authors: Ambrose Don
Published: August 2020

Millions of young people from minority populations suffer from deprivation, segregation, and stigmatization. While a number of scholars have been doing impressive work revealing the nature and nuances of these problems, interdisciplinary investigation can reveal some additional nuances of the phenomena they are studying as well as other phenomena that haven’t yet been considered in depth and detail. This analysis brings together theories and research findings from multiple academic disciplines and professional fields and suggests ways in which the findings could strengthen awareness of the issues deprived young people confront as they move toward adulthood. Topics addressed in the article include the importance of ethical awareness, confined notions of morality, the increasing severity of socioeconomic inequality, and various forms of dogmatic self-deception that prevent the development of widespread ethical thought and action aimed at solving the problems faced by minority youth.

O presente artigo almeja analisar, a partir de revisão bibliográfica e análise de casos jurisprudenciais de referência, a definição da categoria “cadeia de custódia” da prova no processo penal, verificando sua importância e as consequências de sua violação. Diante disso, pretende-se responder às seguintes questões: 1) — O que é a cadeia de custódia da prova no processo penal?, 2) — Qual é a importância de sua proteção? e, 3) — Quais mecanismos podem ser estabelecidos para a sua proteção e quais são as consequências de sua violação? Em termos jurisprudenciais, serão examinados o Habeas Corpus 160.662 do STJ e a Reclamação 32.722 do STF, em razão de sua representatividade na análise da temática da cadeia de custódia nos tribunais superiores brasileiros, ao passo que se trata de casos paradigmáticos de reconhecimento de quebra de cadeia de custódia das provas. Conclui-se que a cadeia de custódia da prova é dispositivo destinado a assegurar a fiabilidade do elemento probatório, impedindo interferências capazes de mascarar o resultado da atividade probatória, devendo-se prever mecanismos para sua proteção e consequências para a sua violação.
Legitimação e procedimento: um debate à luz das perspectivas de Weber, Habermas e Luhmann
Authors: Bachur João Paulo
Published: August 2020

A relação entre moral e política sempre foi um dos objetos centrais da filosofia política e por essa razão, com base nessa premissa, inúmeras teorias foram desenvolvidas com a finalidade de justificar a ação da sociedade humana. O presente trabalho objetiva analisar algumas teorias de legitimação do poder, sobre a ótica de diversos autores clássicos, especialmente Max Weber, Jürgen Habermas e Niklas Luhmann. Para isso, foi realizada uma análise qualitativa de dados, a partir de um estudo bibliográfico meticuloso correlacionando as teorias desses autores sob o fio condutor do procedimento, da linguagem, da intersubjetividade e da comunicação, sendo permitido, a partir dessa análise se criar um panorama crítico sobre essas teorias e projetar seu raciocínio na sociedade. Esse artigo, por fim, demonstra principalmente que as teorias circundantes à comunicação e ao procedimento, presentes tanto em Luhmann quanto em Habermas, são, de certa maneira, conflitantes, embora busquem legitimar o mesmo objeto: o poder.
A complexa definição de ato terrorista como crime contra a humanidade
Authors: Robichez Juliette , Spínola Luíza Moura Costa
Published: August 2020

Os atos de terrorismo constituem um fenômeno global que tem impacto nas questões de paz e de segurança, nacional e internacionalmente. A criação do Tribunal Penal Internacional se deve aos esforços de diversos Estados para instituir um órgão capaz de julgar crimes de elevada repercussão internacional. Quanto ao crime contra a humanidade, há uma discussão acerca de quais poderiam ser os sujeitos ativos: se apenas pessoas vinculadas a um Estado ou se membros de entidades não estatais, como grupos terroristas. Conclui-se que certos grupos terroristas, autores de atentados de grandes proporções e que apresentem alto grau de organização, podem ter seus membros considerados sujeitos ativos de crimes contra a humanidade e, por conseguinte, essas pessoas podem ser julgadas pelo Tribunal Penal Internacional. Nessa perspectiva, foi realizada uma pesquisa qualitativa, bibliográfica, documental e jurisprudencial, com enfoque na literatura brasileira e estrangeira. Preliminarmente, contudo, foi conduzida uma análise crítica, baseada em procedimentos metodológicos comparativos e históricos para entender a dificuldade de se definir o terrorismo, passo indispensável para criar uma norma internacional consensual.

Oil palm (Elaeis guineensis Jacq.) holds a very strategic role in the Indonesia economy. Plants that have reached the economical age of 25 years need to be replanted using qualified oil palm seedling. The qualified seedling is obtained through proper fertilization. The combination of NPK fertilizer and organic material of oil palm empty fruit bunches (OPEFB) which has been given a cellulolytic bacterial consortium can provide sufficient nutrients for the growth of oil palm seedlings. The study aimed to determine the effect of giving a combination of OPEFB organic material, cellulolytic bacterial consortium, and NPK fertilizer on the growth of oil palm seedling (Elaeis guineensis Jacq.) at main nursery. This experiment used a single factor experiment arranged in a Completely Randomized Design (CRD). The treatments were a 100% NPK, a OPEFB compost, a 50% NPK + OPEFB compost, a 50% NPK + OPEFB + Cellulolytic bacterial consortium, and a OPEFB + cellulolytic bacterial consortium. The results showed that the application of inorganic fertilizers combined with organic fertilizers (a OPEFB compost and a OPEFB + cellulolytic bacterial consortium) had a good effect on each parameter. Giving organic fertilizer without inorganic fertilizer had not affected plant growth on all parameters. Application of a OPEFB compost and a OPEFB + cellulolytic bacterial consortium can reduce the use of inorganic fertilizers by 50%.

Published: August 2020

This questions the prevailing approach in the presentation of the concept of slope in teaching undergraduate in Turkey. For this purpose, five mathematics textbooks, were analyzed for problems related to slope, and similarities and differences were revealed. First, the subjects related to the slope in the textbooks were categorized and examined within the context in which they were handled. Therefore, this study is a qualitative study that adopts the interpretive paradigm. These categories are discussed in the form of connectivity, exploration, and purpose using the study for the context (Rezat, 2006). Stump (1999; 2001b) and Moore-Russo et al. (2011) studies were used for cognitive development. These are determined as geometric ratio, behavioral indicator, property determiner, algebraic ratio, parametric coefficient, functional property, linear constant, real life, physical property and trigonometry. Representations of the process skills were chosen as algebraic expressions, tables, and graphics. The concept is discussed in the form of calculus. In the use of technology (Akkoyunlu, 2002; Schware & Jaramillo, 1998), BCS, Scientific and Graphing Calculators, Internet are arranged. Definition, justification, and explanation for performance are arranged. When textbooks are compared, Turkey's textbooks contains more algebraic expressions, the use of the grounds and explanations and real-life connection, contains applications that use more formulas, the description is to use less highlighted is technology, other math they do not explicitly state their links with the subject areas. In general, it was seen that translated textbooks were mostly related to real life, equipped with explanations and justifications requiring cognitive competencies, and proceeded harmoniously between the subject area's main ideas and related ideas. These books use multi-step solved problems. Turkish textbooks need to be reviewed in terms of their functional areas in terms of context, cognitive need, representations, technology, and performance.

There is abundantly documented scientific evidence that the financial transactions that have grown rapidly recently, in conjuction with the interest of the public, were due to the sharp rise in the price of Bitcoin in December 2017. As a consequence, a freshly emerging dataset in the research community has emerged. Therefore, the aim of the present investigation was to examine the analyses of data in this newly emerging dataset in the research community. In order to achieve the extraction of data, their conversion to network and finally their fragmentation, the studied variables were analyzed by using two parts of analysis, namely, statistical network analyses and economic activity analyses. Network statistical analyses was employed aiming to analyze, in a holistic approach, the complex systems of modern times which are represented as networks, as it is impossible to analyze them partially, in order to avoid incorrect conclusions. Additionally, the analyses of economic activity, which is related to indicators from the stock market and the economics of science, was used, after it had been transferred and matched with the economic model represented by Bitcoin. The results distinguished the extent of the data generated by the statistical analyses of the networks and the analyses of economic activity. With respect to data presented, we established that the daily transaction networks were scale free networks which were not evolving like ER random networks and they were not defined as the small world. Also, it was demonstrated that daily transaction networks cannot be reproduced in a random way like ER random networks. Furthermore, the opportunities and problems encountered in conducting the present research were briefly presented.

Textile Industries of Bangladesh confront the environment a huge threat. It produces a huge amount of sludge from effluent treatment plants that is a burden for industries for its high volume and proper treatment cost thereby a huge threat to the environment. The present study aims to characterize the solid sludge of textile industry in terms of pH, organic matter (OM), nutrient elements (N, P, K) and other metal elements through proper analytical methods. The average pH value of the sludge sample was 8.28 along with moisture content 60.64%. The average content of the OM of the studied sludge samples was 11.73% and the average values of N, P and K were 7.57%, 0.52% and 0.50%, respectively. The studied metal (Cr, Zn Mn, Cd, Pb, As and Cu) content of the sludge revealed that the toxic heavy metals Pb, Cd and As were not found in the samples. This study reveals that the amount of OM, N, P and pH is within the Waste concern compost standard (WCCS). The findings clearly show a potentiality of textile sludge as organic manure as they are rich in OM and plant nutrients and free from toxic heavy metals as well.

Published: August 2020

O estudo busca analisar a relação dialógica entre educação e Direitos Humanos de maneira a sugestionar um currículo escolar intercultural, a ser concebido com assente em uma pedagogia decolonial como práticas insurgentes ao atual currículo em um locus-regional – litoral norte do Rio Grande do Sul. Também reflexiona sobre aos protagonismos educativos em conformidade com os Direitos Humanos no contexto da educação brasileira em face dos processos universalizantes que ocupam grande parte das escolas. Torna-se urgente superar o atual modelo de ensino padronizado/ universalizante que atende precário e parcialmente ou sequer atende às demandas regionais, pois outras noções, conceitos e práticas na contemporaneidade, advindos de locais subalternizados, fazem-se presentes e potencialmente aplicáveis. Utiliza-se do procedimento metodológico bibliográfico-investigativo, acrescido de dados e estatísticas do INEP de Censos Escolares (2015, 2016 e 2017).

Published: August 2020

O presente artigo tem como objetivo problematizar as compreensões acerca da função social da escola, apresentada por graduados em cursos de licenciatura de diversas regiões do Brasil. Por meio de formulário online, foram coletadas cinquenta e seis respostas que são analisadas e problematizadas, tendo como base sua análise e categorização. O estudo mobiliza-se por meio de um ensaio com inspirações de Larrosa (2003), conjecturando o percurso de investigação a que se propõem os autores. Emerge do estudo, cinco categorias de análise: cidadania; ensino de conteúdo; mão de obra/formação para o mercado de trabalho; formação humana e integral; sem função social (todas com possíveis compreensões da educação como um direito humano).  As categorias foram atentamente problematizadas, a partir de autores e pesquisadores que nos servem de inspiração para pensar o campo da educação e/ou escolarização. Desta pesquisa, resultam as mais diversas noções de função social da escola no contemporâneo.
Entre hospitalidade e hostilidade: famílias em situação de imigração na rede pública de educação brasileira
Authors: Mendes Leila De Carvalho , Russo Kelly , Barros Kellen Dias de
Published: August 2020

Este artigo apresenta uma reflexão sobre as leis voltadas para imigração e refúgio a partir de uma pesquisa mais ampla realizada numa escola pública da Baixada Fluminense. Partindo de entrevistas com educadoras, famílias e de oficinas pedagógicas realizadas com crianças em situação de imigração/refúgio, seguimos uma perspectiva crítica de educação intercultural e a concepção histórico-cultural para desenvolver reflexões. O recorte trazido para este artigo destaca a dicotomia observada entre o aparato hospitaleiro das leis brasileiras de acolhimento ao refugiado e o cotidiano hostil enfrentado pelas famílias para matricular filhos na escola. Considerando esse objetivo, organizamos o artigo em três sessões: apresentamos os sujeitos da pesquisa e a base teórico-metodológica de nossas análises; tecemos reflexões sobre as leis brasileiras que os acolhem; por fim, tecemos algumas conclusões provisórias, sobre a situação dessas famílias e a responsabilidade do Estado brasileiro em garantir a dignidade humana destas, como das demais famílias que vivem no Brasil.
Direitos humanos e linguísticos e suas relações com a educação de surdos: reflexões a partir do diálogo com estudantes surdos fluentes em Libras
Authors: Mendes Silva Ivone Maria , Remos Silvia Salete
Published: August 2020

Este artigo apresenta reflexões sobre o papel que os direitos humanos e linguísticos podem desempenhar como elementos estruturantes da educação escolar oferecida aos surdos. Abarca contribuições de teóricos das ciências humanas e sociais, além da análise das narrativas de estudantes surdos sobre a importância da Língua de Sinais para seus processos de construção de conhecimento na escola e em outras esferas da vida social. O instrumento de pesquisa utilizado foi a entrevista individual, realizada em Libras, com quatro sujeitos surdos. Os dados foram analisados de acordo com pressupostos da Análise de Conteúdo de Laurence Bardin. Com base nos resultados, conclui-se que a Libras ocupa lugar central na vida dos entrevistados, sendo por eles significada como um direito cujo usufruto repercute no exercício de outros direitos (educacionais, culturais, políticos etc.). Não obstante, ainda precisa ocorrer uma maior difusão e valorização de seu uso nas/pelas escolas, assim como em outros espaços públicos.
