Gravity Concentration in Artisanal Gold Mining
Authors: Veiga Marcello M. , Gunson Aaron J.
Published: November 2020

Worldwide there are over 43 million artisanal miners in virtually all developing countries extracting at least 30 different minerals. Gold, due to its increasing value, is the main mineral extracted by at least half of these miners. The large majority use amalgamation either as the final process to extract gold from gravity concentrates or from the whole ore. This latter method has been causing large losses of mercury to the environment and the most relevant world’s mercury pollution. For years, international agencies and researchers have been promoting gravity concentration methods as a way to eventually avoid the use of mercury or to reduce the mass of material to be amalgamated. This article reviews typical gravity concentration methods used by artisanal miners in developing countries, based on numerous field trips of the authors to more than 35 countries where artisanal gold mining is common.

Published: November 2020

Artificial intelligence (AI) has emerged as a powerful set of tools for engineering innovative materials. However, the AI-aided design of materials textures has not yet been researched in depth. In order to explore the potentials of AI for discovering innovative biointerfaces and engineering materials surfaces, especially for biomedical applications, this study focuses on the control of wettability through design-controlled hierarchical surfaces, whose design is supported and its performance predicted thanks to adequately structured and trained artificial neural networks (ANN). The authors explain the creation of a comprehensive library of microtextured surfaces with well-known wettability properties. Such a library is processed and employed for the generation and training of artificial neural networks, which can predict the actual wetting performance of new design biointerfaces. The present research demonstrates that AI can importantly support the engineering of innovative hierarchical or multiscale surfaces when complex-to-model properties and phenomena, such as wettability and wetting, are involved.

Published: November 2020

Melanogenesis has many important physiological functions. However, abnormal melanin production causes various pigmentation disorders. Melanin synthesis is stimulated by α-melanocyte stimulating hormone (α-MSH) and ultraviolet (UV) irradiation. Lotus seedpod extract (LSE) has been reported as possessing antioxidative, anti-aging, and anticancer activities. The present study examined the effect of LSE on melanogenesis and the involved signaling pathways in vitro and in vivo. Results showed that non-cytotoxic doses of LSE and its main component epigallocatechin (EGC) reduced both tyrosinase activity and melanin production in the α-MSH-induced melanoma cells. Western blotting data revealed that LSE and EGC inhibited expressions of tyrosinase and tyrosinase-related protein 1 (TRP-1). Phosphorylation of p38 and protein kinase A (PKA) stimulated by α-MSH was efficiently blocked by LSE treatment. Furthermore, LSE suppressed the nuclear level of cAMP-response element binding protein (CREB) and disturbed the activation of melanocyte inducing transcription factor (MITF) in the α-MSH-stimulated B16F0 cells. The in vivo study revealed that LSE inhibited melanin production in the ear skin of C57BL/6 mice after exposure to UVB. These findings suggested that the anti-melanogenesis of LSE involved both PKA and p38 signaling pathways. LSE is a potent novo natural depigmenting agent for cosmetics or pharmaceutical applications.

Authors: Yoon Seonyoung , Kim Yoonyoung , Youn Yu Seok , Oh Kyung Taek , Kim Dongin , Lee Eun Seong
Published: November 2020

In this study, we developed γ-cyclodextrin-based multifunctional nanoparticles (NPs) for tumor-targeted therapy. The NPs were self-assembled using a γ-cyclodextrin (γCD) coupled with phenylacetic acid (PA), 2,3-dimethylmaleic anhydride (DMA), poly(ethylene glycol) (PEG), and transferrin (Tf), termed γCDP-(DMA/PEG-Tf) NPs. These γCDP-(DMA/PEG-Tf) NPs are effective in entrapping topotecan (TPT, as a model antitumor drug) resulting from the ionic interaction between pH-responsive DMA and TPT or the host–guest interaction between γCDP and TPT. More importantly, the γCDP-(DMA/PEG-Tf) NPs can induce ionic repulsion at an endosomal pH (~6.0) resulting from the chemical detachment of DMA from γCDP, which is followed by extensive TPT release. We demonstrated that γCDP-(DMA/PEG-Tf) NPs led to a significant increase in cellular uptake and MDA-MB-231 tumor cell death. In vivo animal studies using an MDA-MB-231 tumor xenografted mice model supported the finding that γCDP-(DMA/PEG-Tf) NPs are effective carriers of TPT to Tf receptor-positive MDA-MB-231 tumor cells, promoting drug uptake into the tumors through the Tf ligand-mediated endocytic pathway and increasing their toxicity due to DMA-mediated cytosolic TPT delivery.

This study aimed to assess public knowledge about medicine information, safety, and adverse drug reaction reporting (ADR) in Dammam, Saudi Arabia. A cross sectional study was conducted using purposive stratified sampling in different settings of Dammam city for three months (January–March 2020). The target population was identified as consumers who had used the medicines in the last 3 months. The questionnaire was adopted from the literature and was validated. Content and face validities were established, and reliability was assessed. The study was approved by the concerned ethics committee. A total of 915 participants returned completed questionnaires. A total of 54.4% participants aged between 18 and 30 years, 65.8% were females and 53.1% had obtained bachelor level education. The mean score for knowledge of medicines (K1) was 5.46 ± 1.07. The mean score for knowledge regarding medication safety (K2) was 5.94 ± 1.73. The mean score for tendency to report a suspected ADR (T1) was 3.43 ± 1.57. Gender was a determinant of knowledge regarding medication safety (K2) (p < 0.01) and ADR reporting tendency (T1) (p < 0.01). The marital status of patients was a determinant for both knowledge of medicines (K1) (p < 0.01) and, knowledge regarding medication safety (K2) (p < 0.01). The results of this study highlighted that although the scores for knowledge of medicines, and tendency to report ADR were better, the score for knowledge regarding medication safety was unsatisfactory.
Py–FTIR–GC/MS Analysis of Volatile Products of Automobile Shredder Residue Pyrolysis
Authors: Yang Bin , Chen Ming
Published: November 2020

Automobile shredder residue (ASR) pyrolysis produces solid, liquid, and gaseous products, particularly pyrolysis oil and gas, which could be used as renewable alternative energy resources. Due to the primary pyrolysis reaction not being complete, the yield of gaseous product is low. The pyrolysis tar comprises chemically unstable volatiles before condensing into liquid. Understanding the characteristics of volatile products will aid the design and improvement of subsequent processes. In order to accurately analyze the chemical characteristics and yields of volatile products of ASR primary pyrolysis, TG–FTIR–GC/MS analysis technology was used. According to the analysis results of the Gram–Schmidt profiles, the 3D stack plots, and GC/MS chromatograms of MixASR, ASR, and its main components, the major pyrolytic products of ASR included alkanes, olefins, and alcohols, and both had dense and indistinguishable weak peaks in the wavenumber range of 1900–1400 cm−1. Many of these products have unstable or weaker chemical bonds, such as =CH–, =CH2, –C=C–, and –C=CH2. Hence, more syngas with higher heating values can be obtained with further catalytic pyrolysis gasification, steam gasification, or higher temperature pyrolysis.

Published: November 2020

The consumption of polypropylene (PP) has significantly increased over that of other materials because of its light weight, easy molding, and high mechanical strength. However, the applications of PP are limited, owing to the lack of surface properties, especially with respect to adhesive properties and hydrophilicity. In this study, we developed a surface modification method for enhancing the adhesive properties and hydrophilicity on the PP surface using a side-chain crystalline block copolymer (SCCBC). This method was simple and involved the dipping of a PP film in a diluted SCCBC solution. The optimized modification conditions for enhancing the adhesive properties of PP were investigated. The results revealed that the adhesion strength of PP modified with the SCCBC of behenyl acrylate and 2-(tert-butylamino)ethyl methacrylate was enhanced to 2.00 N/mm (T-peel test) and 1.05 N/mm2 (tensile shear test). In addition, the hydrophilicity of PP modified with the SCCBC of behenyl acrylate and di(ethylene glycol)ethyl ether acrylate was enhanced to a water contact angle of 69 ± 4°. Surface analysis was also performed to elucidate a plausible mechanism for PP modification by the SCCBCs. This surface modification method is facile and enhances desirable properties for the wide application of PP.

Published: November 2020

This study aimed to prepare a new lightweight ultra-high-voltage insulator core filler composite, which can solve the problem of bulkiness. In this study, rigid polyurethane foam pellets with different densities are used as lightweight fillers and polyurethane resins to compound lightweight composite materials. On accounting for working conditions, the density, insulation, heat resistance, water absorption and mechanical properties are tested. The compressive properties of composites are determined by a foam skeleton and a process. Among three kinds of composites, in which the composites with the best comprehensive performance are materials filled with pellets to a density of 0.15g·cm−3. The density, surface resistance, volume resistance, leakage current, initial decomposition temperature, water absorption, force, rupture displacement and limiting oxygen index (LOI) of composites are 0.665 g·cm−3, 1.17 × 1014 Ω, 9.68 × 1014 Ω·cm, 0.079 mA, 208 °C, 0.047%, 2262 N, 2.54 mm, and 23.3%, respectively. The ultra-high-voltage insulator core filler in this study can reduce the weight of the solid core insulator crossarm for Ultra-High Voltage (UHV) by 50–75%.

Do retired professional baseball players become effective coaches? Are Taiwanese coaches up to the job of coaching in the Chinese Professional Baseball League (CPBL)? What are the key coaching factors affecting a CPBL team’s performance in the regular-season? In this study, we examine the key coaching factors affecting the efficiency of CPBL teams from the perspective of efficiency and productivity, using network data envelopment analysis, truncated regression analysis, and bootstrapping methods to provide specific recommendations. We calculated the efficiency of each CPBL team from the 2014 to 2016 regular-seasons. First, the “ex-member” indicator had a significant negative impact on team performance, indicating that a coaching team consisting of coaches with different backgrounds or experience is advantageous to a team’s performance in games; and second, the “ex-professional player” indicator had a significant impact on team performance in the regular season, indicating that the valuable experience of retired professional baseball players definitely has value. The proposed model, after being modified appropriately according to practical needs, can be widely applied to comprehensively track the coaching ability of professional baseball teams and coaches, as well as the players’ ability and efficiency, and will help implement improvements in all aspects of performance management with originality and significant impact.

Published: November 2020

This study investigated the use of brewing wastewater (BW) as the primary carbon source in the Postgate medium for the optimisation of sulphate reduction in acid mine drainage (AMD). The results showed that the sulphate-reducing bacteria (SRB) consortium was able to utilise BW for sulphate reduction. The response surface methodology (RSM)/Box–Behnken design optimum conditions found for sulphate reduction were a pH of 6.99, COD/SO42− of 2.87, and BW concentration of 200.24 mg/L with predicted sulphate reduction of 91.58%. Furthermore, by using an artificial neural network (ANN), a multilayer full feedforward (MFFF) connection with an incremental backpropagation network and hyperbolic tangent as the transfer function gave the best predictive model for sulphate reduction. The ANN optimum conditions were a pH of 6.99, COD/SO42− of 0.50, and BW concentration of 200.31 mg/L with predicted sulphate reduction of 89.56%. The coefficient of determination (R2) and absolute average deviation (AAD) were estimated as 0.97 and 0.046, respectively, for RSM and 0.99 and 0.011, respectively, for ANN. Consequently, ANN was a better predictor than RSM. This study revealed that the exclusive use of BW without supplementation with refined carbon sources in the Postgate medium is feasible and could ensure the economic sustainability of biological sulphate reduction in the South African environment, or in any semi-arid country with significant brewing activity and AMD challenges.
Handling Missing Data in Large-Scale MODIS AOD Products Using a Two-Step Model

Published: November 2020

Aerosol optical depth (AOD) is a key parameter that reflects the characteristics of aerosols, and is of great help in predicting the concentration of pollutants in the atmosphere. At present, remote sensing inversion has become an important method for obtaining the AOD on a large scale. However, AOD data acquired by satellites are often missing, and this has gradually become a popular topic. In recent years, a large number of AOD recovery algorithms have been proposed. Many AOD recovery methods are not application-oriented. These methods focus mainly on to the accuracy of AOD recovery and neglect the AOD recovery ratio. As a result, the AOD recovery accuracy and recovery ratio cannot be balanced. To solve these problems, a two-step model (TWS) that combines multisource AOD data and AOD spatiotemporal relationships is proposed. We used the light gradient boosting (LightGBM) model under the framework of the gradient boosting machine (GBM) to fit the multisource AOD data to fill in the missing AOD between data sources. Spatial interpolation and spatiotemporal interpolation methods are limited by buffer factors. We recovered the missing AOD in a moving window. We used TWS to recover AOD from Terra Satellite’s 2018 AOD product (MOD AOD). The results show that the MOD AOD, after a 3 × 3 moving window TWS recovery, was closely related to the AOD of the Aerosol Robotic Network (AERONET) (R = 0.87, RMSE = 0.23). In addition, the MOD AOD missing rate after a 3 × 3 window TWS recovery was greatly reduced (from 0.88 to 0.1). In addition, the spatial distribution characteristics of the monthly and annual averages of the recovered MOD AOD were consistent with the original MOD AOD. The results show that TWS is reliable. This study provides a new method for the restoration of MOD AOD, and is of great significance for studying the spatial distribution of atmospheric pollutants.

Published: November 2020

Wuhan, the largest city in central China, has experienced rapid urban development leading to land subsidence as well as environmental concerns in recent years. Although a few studies have analyzed the land subsidence of Wuhan based on ALOS-1, Envisat, and Sentinel-1 datasets, the research on long-term land subsidence is still lacking. In this study, we employed multi-temporal InSAR to investigate and reveal the spatiotemporal evolution of land subsidence over Wuhan with ALOS-1, Envisat, and Sentinel-1 images from 2007–2010, 2008–2010, 2015–2019, respectively. The results detected by InSAR were cross-validated by two independent SAR datasets, and leveling observations were applied to the calibration of InSAR-derived measurements. The correlation coefficient between the leveling and InSAR has reached 0.89. The study detected six main land subsidence zones during the monitoring period, with the maximum land subsidence velocity of −46 mm/a during the 2015–2019 analysis. Both the magnitude and the extent of the land subsidence have reduced since 2017. The causes of land subsidence are discussed in terms of urban construction, Yangtze river water level changes, and subsurface water level changes. Our results provide insight for understanding the causes of land subsidence in Wuhan and serve as reference for city management for reducing the land subsidence in Wuhan and mitigating the potential hazards.

Published: November 2020

A paramount challenge of prohibiting increased CO2 emissions for network densification is to deliver the Fifth Generation (5G) cellular capacity and connectivity demands, while maintaining a greener, healthier and prosperous environment. Energy consumption is a demanding consideration in the 5G era to combat several challenges such as reactive mode of operation, high latency wake up times, incorrect user association with the cells, multiple cross-functional operation of Self-Organising Networks (SON), etc. To address this challenge, we propose a novel Mobility Management-Based Autonomous Energy-Aware Framework for analysing bus passengers ridership through statistical Machine Learning (ML) and proactive energy savings coupled with CO2 emissions in Heterogeneous Network (HetNet) architecture using Reinforcement Learning (RL). Furthermore, we compare and report various ML algorithms using bus passengers ridership obtained from London Overground (LO) dataset. Extensive spatiotemporal simulations show that our proposed framework can achieve up to 98.82% prediction accuracy and CO2 reduction gains of up to 31.83%.

Bodybuilding is a sport that requires adequate training strategies in order to maximize skeletal muscle hypertrophy. The purpose of the present review was to perform a narrative assessment of the training routines designed for muscle hypertrophy used by bodybuilders. A search was carried out in the databases Pubmed/MEDLINE, Scielo, EBSCO, LILACS, SportDiscus, Web of Science, and CINAHL with the words “Resistance training” and “hypertrophy” in bodybuilders and their variations that involve the respective outcomes. Fourteen studies were identified that investigated the long-term training routines of bodybuilders. These studies demonstrate a pattern in the training organization, whereby there is a separation of training into four distinct periods: off-season, pre-contest, peak week, and post-contest. Each period has a specific spectrum of intensity load, total training volume, and exercise type (multi- or single-joint). We conclude that bodybuilding competitors employed a higher intensity load, lower number of repetitions, and longer rest intervals in the off-season than pre-contest.

The advent of the Internet has significantly changed consumption patterns and habits. Online grocery shopping is a way of purchasing food products using a web-based shopping service. The current COVID-19 pandemic is determining a rethinking of purchase choice elements and of consumers’ behavior. This work aims to investigate which characteristics can affect the decision of online food shopping during the pandemic emergency in Italy. In particular, the work aims to analyze the effects of a set of explanatory variables on the level of satisfaction for the food online shopping experience. For achieving this aim, the proportional odds version of the cumulative logit model is carried out. Data derive from an anonymous on-line questionnaire administrated during the first months of the pandemic and filled by 248 respondents. The results of this work highlight that people having familiarity with buying food online, that have a higher educational level and consider food online channels easy to use, appear more satisfied for the food online shopping experience. These findings can be crucial for the future green global challenges as online shopping may help to reach competitive advantages for company sustainability.

Published: November 2020

Rice paddy fields, considered as a human-made wetland ecosystems, play important roles in food production and ecosystem conservation. Nowadays, rice cultivation in the Mekong Delta, Vietnam, is under severe threat from climate changes, yet there is a shortage of documented information and research on rice production under future climate. Hence, the present study investigates the impacts of climate change on rice cultivation in the MD using an ensemble-modelling approach, implemented by biomod2 platform in R software. Rice cultivation occurrence points, eco-physiological and bioclimatic data were utilised to model habitat suitability for rice cultivation under current and future climate, RCP 4.5 and RCP 8.5 scenarios of the year 2050. The ensemble model obtained acceptable accuracy with scores of 0.880, 0.993 and 0.960 for KAPPA, ROC/AUC and TSS, respectively. Simulation results show that the mean loss of suitable land and mean gain of unsuitable land were 31.4% and 64.6%, respectively, for the year 2050 compared to the present. Salinity intrusion, increases in precipitation during rainy season and decreases in precipitation during dry season were key factors driving the loss of suitable habitat. The findings of this study critically support policy makers and planners in developing appropriate strategies for adaptation and mitigation in response to climate change for sustainable rice cultivation.
The Structure of an AAV5-AAVR Complex at 2.5 Å Resolution: Implications for Cellular Entry and Immune Neutralization of AAV Gene Therapy Vectors

Published: November 2020

Adeno-Associated Virus is the leading vector for gene therapy. Although it is the vector for all in vivo gene therapies approved for clinical use by the US Food and Drug Administration, its biology is still not yet fully understood. It has been shown that different serotypes of AAV bind to their cellular receptor, AAVR, in different ways. Previously we have reported a 2.4Å structure of AAV2 bound to AAVR that shows ordered structure for only one of the two AAVR domains with which AAV2 interacts. In this study we present a 2.5Å resolution structure of AAV5 bound to AAVR. AAV5 binds to the first polycystic kidney disease (PKD) domain of AAVR that was not ordered in the AAV2 structure. Interactions of AAV5 with AAVR are analyzed in detail, and the implications for AAV2 binding are explored through molecular modeling. Moreover, we find that binding sites for the antibodies ADK5a, ADK5b, and 3C5 on AAV5 overlap with the binding site of AAVR. These insights provide a structural foundation for development of gene therapy agents to better evade immune neutralization without disrupting cellular entry.

Published: November 2020

INTRODUÇÃO: Mediante os problemas alimentares e nutricionais de hoje, a Educação Alimentar e Nutricional (EAN) se consolida como uma importante estratégia de promoção da saúde, principalmente na infância, por ser um momento em que o comportamento alimentar é construído. Suas ações baseiam-se em diferentes abordagens educacionais e pedagógicas que propiciam o diálogo e a reflexão sobre aspectos relacionados à alimentação e à nutrição ao longo da vida dos indivíduos. OBJETIVO: Apresentar a experiência vivenciada com a aplicação de atividades lúdico-pedagógicas em EAN para pré-escolares de uma instituição de ensino. METODOLOGIA: Trata-se de um relato de experiência de caráter qualitativo que descreve o desenvolvimento de um projeto de intervenção nutricional por meio de atividades de EAN, denominado Nutrindo o Saber, realizado em uma escola privada, localizada na área urbana do município de Visconde do Rio Branco, estado de Minas Gerais, durante o período de agosto a outubro de 2017. Foram realizados nove encontros na escola, com duração de 60 minutos cada um. Dentre os métodos de ensino utilizados, incluíram-se expositivos-dialógicos, oficinas culinárias, práticas de análise sensorial e teatro de fantoches, de modo que o processo educativo acontecesse de maneira dinâmica e bilateral. Em todas as atividades, utilizou-se como referencial teórico o Guia Alimentar para a População Brasileira. RESULTADOS E DISCUSSÃO: A amostra foi constituída por 56 pré-escolares e escolares de 2 a 7 anos. Ao final das atividades, por meio de um questionário, foi perguntado aos responsáveis se essas ações foram eficientes na mudança dos hábitos alimentares das crianças: 85,70% respondeu que sim. A EAN trabalhada de maneira lúdica, além de aproximar o conhecimento científico do universo infantil, também acelera o processo de aprendizagem proporcionando oportunidades de participação do público-alvo, desmitificando a teoria sobre o educando ser somente o receptor; e o educador, o detentor do conhecimento. Com o intuito de tornar as atividades prazerosas tanto para o educador quanto para o educando, procurou-se estabelecer um vínculo afetivo entre eles durante as ações de educação nutricional. CONCLUSÃO: Considera-se que as atividades propostas cumpriram seus objetivos de proporcionar conhecimento sobre alimentação saudável, sensibilizando o público para a adoção de hábitos alimentares saudáveis.

O objetivo deste estudo foi analisar o planejamento regional para o enfrentamento das doenças crônicas não transmissíveis (DCNT) na 29ª Região de Saúde do Rio Grande do Sul e comparar com as metas nacionais do Plano de Ações Estratégicas para o Enfrentamento das DCNT no Brasil (2011–2022). Pesquisa descritiva, com abordagem quantitativa, por meio de análise documental de pautas e atas de reuniões da Comissão Intergestores Regional (CIR) de 2014 e de cinco planos municipais de saúde do período 2014–2017. Identificaram-se debates relacionados ao enfrentamento das DCNT nos pontos de pauta e atas das reuniões da CIR; contudo, estes são pouco relacionados à promoção da saúde. A análise do diagnóstico situacional dos planos apresentou ausência de informações importantes, como perfil de morbimortalidade e metas relacionadas à gestão, ao monitoramento e à avaliação. Entre os objetivos propostos pelos planos municipais, quatro contemplaram 10 das 12 metas nacionais, com exceção ao consumo de frutas e hortaliças e ao tratamento das lesões precursoras de câncer. Para qualificar o enfrentamento das DCNT, ações relacionadas à promoção da saúde e avaliação precisam integrar o planejamento regional em saúde.
The challenges imposed by L2 inflectional morphology: evidence from speeded acceptability judgment tasks with Brazilian Portuguese-English bilinguals
Authors: Candido  , Ricardo  , Bruna
Published: November 2020

The purpose of the present study was to contribute to current documented evidence of the challenges imposed by inflectional morphology in second language acquisition. We conducted two speeded acceptability judgment tasks with Brazilian Portuguese-English bilinguals with different linguistic profiles. We analyzed their behavior with respect to grammatical and ungrammatical sentences in English involving inflectional morphology. Our results suggested that the bilingual speakers differed from English native speakers only with respect to the sentences with missing inflectional morphemes regardless of proficiency level and immersion status. We understand these findings as an indication that difficulty with functional morphology involves perceptual salience and possibly learned attention to linguistic cues.

Published: November 2020

Os fenômenos da aquisição fonético-fonológicos específicos a homens e mulheres são, relativamente, pouco explorados. Os estudos fazem, frequentemente, médias com os dados de produção fonética de homens e mulheres, com o fim de neutralizar o efeito das diferenças de sexo. Este estudo pretende investigar a aquisição da duração vocálica do inglês americano como produzida por falantes mulheres e homens falantes nativos de português brasileiro. Os resultados mostraram que as mulheres produzem vogais mais longas do que os homens tanto no grupo controle monolíngue quanto no grupo experimental bilíngue. As análises estatísticas indicam que os efeitos relativos às diferenças entre sexo e os efeitos relativos à aquisição de L2 não estão correlacionados. Tais resultados são interessantes para argumentamos em favor de que estudos em aquisição de L2 e fonética devem sempre considerar as diferenças de aquisição e performance entre os sexos, a fim de que importantes fenômenos específicos ao sexo não sejam ignorados.
O recurso à observação como estratégia de formação inicial docente
Authors: Cabrita Condessa Isabel
Published: November 2020

Com este artigo, temos como propósito conhecer as potencialidades e limitações da utilização da observação nos estágios pedagógicos do 1.º Ciclo do Ensino Básico. Após uma breve passagem pelos relatórios de estágio, com temática de aprofundamento no âmbito das Expressões (Artísticas e Físico-Motoras) e do recurso à Pedagogia Lúdica - duas temáticas investigadas pelos estagiários de uma mesma instituição, entre 2014 e 2018. Como instrumento usámos a análise documental - das atividades planeadas, desenvolvidas e das reflexões partilhadas no relatório. Da análise de conteúdo efetuada, sublinhamos as potencialidades da observação nas “notas” deixadas sobre três situações de estágio: compreensão do contexto educativo, reajuste da intervenção pedagógica e aprofundamento da temática. As limitações prenderam-se mais com a falta de treino de observação, a escassez do uso de grelhas e falta de coerência entre os discursos e as práticas dos profissionais.
The deposition of dogs (Canis familiaris) at Satu Nou – Valea lui Voicu (Babadag culture)
Authors: Bălășescu Adrian , Ailincăi Sorin-Cristian
Published: November 2020

The archaeozoological study carried out in Satu Nou – Valea lui Voicu (Oltina, Constanța County) provides new information on the relationship between humans and dogs in the early period of the Iron Age. Thus, numerous bones from several dogs (Canis familiaris) were identified in the feature called “ ditch or gully” and in a pit (Pit 41). The authors of the research attributed this context, stratigraphically considered the oldest, to the Babadag culture (10th– 9th centuries BC). The studied group includes the complete and partial skeletons of 14 individuals (12 identified in the ditch and two in Pit 41), unearthed in the 1991– 1992 seasons. Some dogs (at least four individuals) were slaughtered by blows to the skull and / or were eaten (at least five individuals) as evidenced by the disarticulation and defleshing cut marks identified on the bones. Given the special archaeological situation at Satu Nou, the phenomenon of cynophagy must be viewed in a ritual and funerary context. Of the 14 dogs, two are certainly males, two are possibly males and four are possibly females. The animals were predominantly slaughtered at a young age : nine are subadults (between 8 and 18 months) and five are adults. The average withers height of these animals is 50.2 cm (n = 5 ; limits 46– 55.6 cm) after Koudelka and 51 cm (n = 5 ; limits 47.4– 56.8 cm) after Harcourt ; the gracility index average is 7.4 (n = 5 ; limits 6.6– 8.3). These figures describe medium-sized and above-average dogs of medium robustness. It is very interesting that nine of these individuals have extremely varied pathologies affecting various anatomical parts, from the skull to the phalanges. Most of these pathologies healed in the individuals’ lifetime, but they illustrate that these animals have gone through various accidents or traumas, some of them at relatively young ages. In general, the dog had a wide range of attributes : psychopomp creature, companion of the warrior and hunter, and also guardian of the home, with a therapeutic and purifying role. In our case the dog was sacrificed (sometimes violently), deposed as an offering and sometimes probably ritually consumed. It should not be omitted that in the same ditch from Valea lui Voicu were identified human bones (from 26 individuals), pottery, but also numerous animals remains that could have been part of the funerary banquets that probably took place in this area. The association of all these archaeological, anthropological and archaeozoological materials may suggest the existence of dog sacrifices at the funerals of the deceased (as their companions) and the deposition of a part of the animal near the body, while the rest of the animal was consumed during the funerary ceremony.
La Numancia de Rafael Alberti en la guerra civil española
Authors: Nicoloff Silverio Adriana
Published: November 2020

El 18 de julio de 1936 se produce el levantamiento militar que desencadena la guerra civil española, enfrentando a los bandos nacionalista y republicano. En este contexto emerge el denominado teatro de urgencia, cuya finalidad era funcionar como un instrumento de agitación y propaganda al servicio de la causa republicana. Se planteaba combinar la temática revolucionaria coetánea con los clásicos del teatro del Siglo de Oro, porque poseían una conexión con las masas populares que los dramaturgos contemporáneos no podían ignorar. En 1937, Rafael Alberti se apropia de la Numancia cervantina, adaptándola y poniéndola al servicio de la causa republicana, por su ejemplo heroico, cuando comienza la ofensiva nacionalista sobre Madrid y es imperioso alentar a los combatientes y a la población civil en la resistencia. El texto albertiano está hecho en vistas de la lucha y resistencia republicana y no se vislumbra una posible derrota, pues los españoles se convertirán en los vengadores de Numancia. El presente trabajo aborda la Numancia de 1937, su proceso de reescritura a través del paradigma de la hipertextualidad de Gerard Genette, la resignificación del texto cervantino en el contexto bélico español, y cómo esta versión funciona como un parapeto ideológico para exaltar los valores republicanos.

Published: November 2020

One of the prerequisites for a healthy human life is access to drinking water through a public water supply service and the drainage of wastewater and polluted water using public drainage services. The Constitution of the Republic of Croatia guarantees the right to a healthy life, and the State should provide conditions for a healthy environment. The United Nations General Assembly Resolution no. 64/292 of 2010 recognizes the right to safe and clean drinking water as a human right of great importance for the full enjoyment of other human rights. The paper will present some of the indicators of access to public water supply and sewerage services, such as: percentage of connection to the public water supply system, residential water consumption, access to flushing toilets, connection to the public sewerage and connection to the wastewater treatment plant. The analysis will be made for the following countries: Albania, Austria, Bosnia and Herzegovina, Bulgaria, Croatia, Montenegro, Romania, Serbia, Slovakia and Slovenia. At the end of the paper, a conclusion will be drawn, taking into account the observed indicators for the analyzed countries.
