Estrategias metacognitivas de comprensión de lectura en el aula de español como segunda lengua o lengua extranjera
Authors: López Jurado Ana Ligia
Published: June 2018

En este artículo se expone qué son y cómo se pueden implementar las estrategias metacognitivas de comprensión de lectura en una clase de español como segunda lengua (L2) o como lengua extranjera (ELE). Se toman en cuenta los tres componentes de la metacognición: el conocimiento declarativo, procedimental y condicional aplicados en el aula como procesos metacognitivos: planificación, monitoreo y control y evaluación. Estas estrategias promueven la autonomía del estudiante al monitorear, controlar y evaluar su propio proceso de aprendizaje (Hall, 1991; Pintrich, 2002; Jiménez-Rodríguez, 2004; Muhammand Al-Khateeb, 2011; Alhaqbani & Riazi, 2012). Además, estas estrategias aplicadas a las segundas lenguas han permitido que los estudiantes tengan un mejor rendimiento en cuanto a la comprensión lectora (Brantmeir, 2003; Yang, 2002; Farrell, 2001).
Estados Unidos y su dimensión lingüística
Authors: Betti Silvia
Published: June 2018

El presente ensayo muestra el estado del español ‘en’ y ‘de’ los Estados Unidos y del llamado –popularmente– spanglish, a través de las reflexiones de varios estudiosos sobre el tema. El cambio de códigos (code-switching) y la mezcla de códigos (code-mixing) entre el inglés y el español –manifestaciones que diversos investigadores consideran típicas del spanglish–, representan el modelo de la identidad mestiza de muchos latinos en los Estados Unidos. En este trabajo se pretende también observar el spanglish desde la perspectiva de las identidades mixtas en contextos interculturales. Finalmente, tratamos de reflexionar sobre algunos puntos para intentar profundizar y comprender la compleja situación del español en este país, y del tan discutido spanglish.

El desarrollo de la competencia transcultural durante el estudio en el extranjero
Authors: Pereira Isabel , Martínez-Arbelaiz Asunción
Published: June 2018

Es una realidad que la universidad actual trata de proporcionar facilidades económicas y académicas de forma que los alumnos universitarios hagan parte de sus estudios en otro contexto cultural diferente al propio. Las ganancias de este esfuerzo por parte de la administración y de los propios estudiantes son a menudo difíciles de cuantificar. En el campo de la adquisición de lenguas, se suele señalar que los alumnos que estudian la lengua meta rodeados de esta, son superiores a los alumnos que la estudian solamente en el aula (Howard, 2001; 2005; Martínez-Arbelaiz y Pereira, 2008; Meara, 1994; Milton y Meara, 1995; Pérez-Vidal y Juan-Garau, 2009; Pérez-Vidal, 2014; Segalowitz y Freed, 2004). Sin embargo, contamos con pocas investigaciones sobre cómo esta experiencia repercute en el desarrollo de la competencia transcultural (Modern Language Association, 2007), uno de los objetivos de cualquier currículum de lenguas. Por medio de un análisis de grabaciones de discurso de aula, observamos tres clases de tres cursos diferentes y de pequeño tamaño. Constatamos que los alumnos estadounidenses que estudian en Madrid son observadores críticos de la comunidad que les acoge y que estas observaciones les llevan a cuestionar y refinar ideas anteriores sobre la sociedad española.
Historical storage cellars in Budapest
Authors: Pilsitz Martin , Nádasi-Antal Zsuzsanna
Published: June 2018

The Kőbánya district of Budapest is situated on the eastern margins of the Hungarian capital city. Beneath Kőbánya there is an extensive limestone layer, in which tunnels and passages have been made, ‍some of which appear to date from the 13th century. In the 19th century, the limestone caverns of Budapest-Kőbánya were used for the refrigeration of perishable goods in large quantities. The caverns‍ represent one of Budapest’s historical industrial landmarks, although their architectural history has not been documented in full. This article analyses the architectural development of these evidently low-tech‍ facilities, while also exploring their significant role in the city’s urbanisation. The technical functions and structure of the system of caverns may be useful as a resource for society in the future when the supply‍ of fossil fuels runs out. The effectiveness of the caverns as places for refrigeration can be demonstrated through climatic calculations. The cavern system has significant energy capabilities, given that there is a‍constant air temperature throughout the year. The vast amount of geothermal energy could be used to cool heat pumps or heat exchangers. The results of measurements taken in preparation for this article are‍ presented.

ABSTRACT Objective: to evaluate the primary outcome of local complications and late recurrence in patients with hidradenitis suppurativa undergoing radical resection and specific reconstruction. Methods: we conducted a retrospective analysis of the medical records of patients attended by the Plastic Surgery Service of the Clinics Hospital, Medical School, USP, between 2010 and 2016. We included patients who underwent radical resection of hidradenitis suppurativa in advanced stage and reconstruction through primary closure, grafts or flaps. Results: we analyzed 34 lesions in 19 patients, of which 64.5% had local complications, though with 73.5% efficient healing after 12 weeks postoperatively. We observed late recurrence in 47%, but in isolation, 22.2% of the reconstructions with locoregional flaps had recurrence after one year. Conclusion: extensive and radical resection of the disease associated with locoregional flap coverage (pedicled or perforating) has been shown to be the best management in terms of late results.

Published: June 2018

O objetivo do presente estudo foi demonstrar a aplicação de uma etapa de pós-processamento determinístico, baseada em medidas de similaridade, para aumentar a performance do relacionamento probabilístico com e sem a etapa de revisão manual. As bases de dados utilizadas no estudo foram o Sistema de Informação de Agravos de Notificação e o Sistema de Informações sobre Mortalidade, no período de 2007 a 2015, do Município de Palmas, Tocantins, Brasil. O software probabilístico utilizado foi o OpenRecLink; foi desenvolvida e aplicada uma etapa de pós-processamento determinístico aos dados obtidos por três diferentes estratégias de pareamento probabilístico. As três estratégias foram comparadas entre si e acrescidas da etapa de pós-processamento determinístico. A sensibilidade das estratégias probabilísticas sem revisão manual variou entre 69,1% e 77,8%, já as mesmas estratégias, acrescidas da etapa de pós-processamento determinístico, apresentaram uma variação entre 92,9% e 96,3%. A sensibilidade de duas estratégias probabilísticas com revisão manual foi semelhante à obtida pela etapa de pós-processamento determinístico, no entanto, o número de pares destinados à revisão manual pelas duas estratégias probabilísticas variou entre 1.177 e 1.132 registros, contra 149 e 145 após a etapa de pós-processamento determinístico. Nossos resultados sugerem que a etapa de pós-processamento determinístico é uma opção promissora, tanto para aumentar a sensibilidade quanto para reduzir o número de pares que precisam ser revisados manualmente, ou mesmo para eliminar sua necessidade.

ABSTRACT Background: Liver elastography have been reported in hepatocellular carcinoma (HCC) with higher values; however, it is unclear to identify morbimortality risk on liver transplantation waiting list. Aim: To assess liver stiffness, ultrasound and clinical findings in cirrhotic patients with and without HCC on screening for liver transplant and compare the morbimortality risk with elastography and MELD score. Method: Patients with cirrhosis and HCC on screening for liver transplant were enrolled with clinical, radiological and laboratory assessments, and transient elastography. Results: 103 patients were included (without HCC n=58 (66%); HCC n=45 (44%). The mean MELD score was 14.7±6.4, the portal hypertension present on 83.9% and the mean transient elastography value was 32.73±22.5 kPa. The median acoustic radiation force impulse value of liver parenchyma was 1.98 (0.65-3.2) m/s and 2.16 (0.59-2.8) m/s in HCC group. The HCC group was significantly associated with HCV infection (OR 26.84; p<0.0001), higher levels of serum alpha-fetoprotein (OR 5.51; p=0.015), clinical portal hypertension (OR 0.25; p=0.032) and similar MELD score (p=0.693). The area under the receiver operating characteristics (AUROC) showed sensitivity and specificity for serum alpha-fetoprotein (cutoff 9.1 ng/ml), transient elastography value (cutoff value 9 kPa), and acoustic radiation force impulse value (cutoff value 2.56 m/s) of 50% and 86%, 92% and 17% and 21% and 92%, respectively. The survival group had a mean transient elastography value of 31.65±22.2 kPa vs. 50.87±20.9 kPa (p=0.098) and higher MELD scores (p=0.035). Conclusion: Elastography, ultrasound and clinical findings are important non-invasive tools for cirrhosis and HCC on screening for liver transplant. Higher values in liver elastography and MELD scores predict mortality.
O Brasil entre a memória, o esquecimento e a (in)justiça: uma análise do julgamento da ADPF nº 153 pelo Supremo Tribunal Federal
Authors: Gallo Carlos Artur
Published: June 2018

Resumo Em abril de 2010, o Supremo Tribunal Federal (STF) levou a julgamento a Arguição por Descumprimento de Preceito Fundamental (ADPF) nº 153. Proposta em outubro de 2008 pelo Conselho Federal da Ordem dos Advogados do Brasil (OAB), a ADPF nº 153 questionava a interpretação corrente da Lei de Anistia (Lei nº 6.683/1979), segundo a qual os envolvidos nos crimes cometidos pelo aparato repressivo teriam sido automaticamente anistiados pela norma editada durante o processo de transição à democracia. Este estudo analisa o impacto que o processo de transição à democracia brasileiro teve no novo cenário político iniciado com o fim da ditadura, verificando as conexões entre o posicionamento emitido pela mais alta instância do Judiciário no país e a forma como se deu a transição da ditadura para a democracia.

ABSTRACT Brazil is the second largest soybean producer in the world, with a yield of around 96.2 million tons per crop. This high yield leads to a great amount of waste resulting from soybean cultivation, which can reach approximately 41 million tons of waste per year. This material has lignocellulosic properties, which may enable its use as a raw material for particleboard production. Therefore, the objective of this study was to evaluate the use of soybean pods in particleboard production. For particleboard manufacture, wood of the hybrid Eucalyptus urophylla and Eucalyptus grandis was used, added with soybean pods, at proportions of 0%, 25%, 50%, 75% and 100%. For particleboard evaluation, a completely randomized design was used, with five treatments and three replicates, using linear regression and the Scott-Knott test at 5% significance for comparison among the different treatments. The properties apparent density, compaction ratio, water absorption after 2 and 24 hours, thickness swelling after 2 and 24 hours in water immersion, internal bonding, modulus of rupture and modulus of elasticity in bending properties were evaluated. The ratio soybean pod waste and eucalyptus particles in the panels led to an increase in water absorption values and thickness swelling, in addition to a decrease in mechanical properties. The production of panels with approximately 23% soybean pods is feasible.

ABSTRACT The knowledge of physiological and biochemical aspects occurring at the postharvest phase of flowers is critical to guide efficient conservation techniques for maintaining quality and longevity. Factors that cause deterioration of cut flowers after harvest are dehydration, low carbohydrate contents, the presence of microorganisms in vase solution or stem and late stage of development at harvest. Thus, the objective was to determine the effect of harvest stages of calla lily stems and storage solutions on water relations and contents of starch and sugars. Flower stems were harvested in the following opening stages of the spathe: early-stage (cartridge) and 1/3 open and were arranged in six storage solutions containing 1, 2, 4 and 6% glucose and the controls with water and solution with 5% sucrose. Results indicate that at early-stage and 1/3 open harvesting stages, the addition of glucose at concentrations of 4% and 6% stimulated flower opening. Calla lily flower stems maintained in water and in solution with 1% glucose had lower percentages of fresh weight loss and better maintenance of water balance, with a small reduction in the contents of starch and soluble sugars. The addition of sugars in the storage solution was efficient in opening early-harvested stems. Harvest the floral stems in initial stages allow the maintenance of the commercial quality for longer period, without pollen production. The use of water relations allowed the determination of the better sugar concentration for the conservation of open-harvest of floral stems.

Abstract The fish fauna of eight streams with different land uses of their watersheds (forested and rural areas) in the lower Iguaçu River basin was inventoried, in order to evaluate the composition and species richness. The fishes were sampled quarterly from May 2015 to February 2016, using the electrofishing technique. In total, 4,239 individuals were captured, belonging to six orders, 11 families and 26 species. The orders Siluriformes and Characiformes, and the families Characidae and Trichomycteridae were the most specious. Of the total species sampled, 65% were endemic to the Iguaçu River basin, four are not described and four are non-native. As expected to the Iguaçu River basin, the inventoried fauna revealed low richness and high endemism, however was highly nested within the species composition reported for main channel of Iguaçu River and their larger tributaries. The species recorded here corresponded to a subset of 24.5% of the 106 species documented for the basin. The streams presented different faunas, with only two species (Astyanax bifasciatus and Trichomycterus stawiarski) common to both forested and rural streams. In addition, higher species richness was recorded in streams inserted in conservation units. The presence of non-native species was more frequent in rural streams. These results highlight the importance of the preservation of forested areas in the watersheds of lower Iguaçu, which presents a peculiar fish fauna, along with several threats to biodiversity such as habitat loss by intensive agriculture use.

Resumo O congelamento de células é uma importante ferramenta na preservação de espécies ameaçadas de extinção. Células fetais de cultivo primário obtidas de um bovino clone foram submetidas à pressão negativa (PN) de 200, 500 ou 800 mbar, imediatamente (PN0h) ou três horas antes (PN3h) do congelamento em palhetas finas, com 10% de DMSO como crioprotetor. Células frescas e congeladas sem submissão à PN foram utilizadas como controles. Avaliou-se a viabilidade pós-descongelamento, a curva de proliferação celular, assim como o tempo de duplicação da população (PDT) celular, a cada 24 horas, durante oito dias. Os dados obtidos foram submetidos ao teste de Tukey ou Qui quadrado (P≤0,05). A sobrevivência média dos grupos controle (89,8%) e PN500 0h (88,1%) foi superior aos outros grupos; o tempo de PDT foi semelhante nos grupos fresco (27,5 ± 0,35 h), controle congelado (30,1 ± 2,3 h) e PN500 0h (32,4 ± 1,6 h). O menor tempo foi observado no grupo PN800 0h (21,9 h). O congelamento de células fetais bovinas de cultivo primário, realizado em palhetas de 0,25 mL, com 10% de DMSO, possibilita elevadas taxas de sobrevivência após o descongelamento. A PN modifica a curva de crescimento de células criopreservadas, sendo que as intensidades de 200 ou 500 mbar, aplicadas imediatamente antes do congelamento das células, possibilitam curvas de proliferação semelhantes às obtidas com células frescas.

Published: June 2018

ABSTRACT This study aimed to characterize three natural populations of mangabeira (Hancornia speciosa) located in parts of the Cerrado in the region of Porto Nacional, State of Tocantins, as well as to evaluate phenotypic variability in individual plants based on the physicochemical properties of their fruits. Ten genotypes were selected from each population, and 20 fruits of each genotype were collected for analysis. Fruits were analyzed for transverse and longitudinal diameters, total mass, pulp mass and yield, and number and fresh mass of seeds. Two seeds were taken from each fruit for the measurement of longitudinal and transverse diameter and thickness. Furthermore, pH and soluble solids were measured in the total pulp of each genotype. Descriptive statistics were performed on the data from morphological characterization, and populations were compared by the Kruskal-Wallis test, followed by Dunn's test at 5% probability level. The relationship between variables was estimated by the Spearman’s correlation coefficient. Phenotypic variability was verified using the principal component analysis. All three natural populations of mangabeira investigated here exhibited similar characteristics regarding fruit morphology and pH. Significant differences were detected only in the transverse diameter of the seed (Canaã had the highest value) and for total soluble solids content (Providência had the highest value). Significant correlations were found for corresponding morphological variables and pH in each population, except for several negative correlations that were observed in the Canaã population, which produced more homogeneous fruit. The Providência population presented the largest and most massive fruit. The greatest phenotypic variabilities were observed in the São Judas Tadeu and Providência populations.

ABSTRACT Irrigation with saline water is a worldwide necessity an excess of salts in water or in soil causes growth inhibition, and negatively affects the productivity of many crops. Application of nitrogen fertilizers may be a way of mitigating the effects of salts on plants. The aim of this study was to evaluate the accumulation of biomass and the chlorophyll pigment content in jackfruit seedlings irrigated with water of increasing salinity level in soil with nitrogen sources. The treatments were distributed in randomized blocks with four replicates and three plants per plot, arranged in a 5 × 3 factorial scheme, related to electrical conductivity levels of the irrigation water of 0.3, 1.0, 2.0, 3.0 and 4.0 dS m-1, in soil without nitrogen, with ammonium sulfate and with urea, in a split application 60 and 75 days after sowing. An increase in the salinity of the water increased the salinity levels of soil, which was intensified by a dose of 150 mg of N, mainly when applied in the form of ammonium sulfate, inhibiting dry matter production and chlorophyll content in jackfruit seedlings. The greatest reductions in chlorophyll a and b content occurred in jackfruit seedlings irrigated with water of 4.0 dS m-1 conductivity in the soil without nitrogen fertilization. Urea is the most suitable nitrogen source for the production of seedlings under conditions of high salinity.

ABSTRACT Plasma technology is a fast, cost-effective, and pollution-free method that can be used in place of conventional methods to overcome seed dormancy. The goal of the present study was to determine the effect of different application times of atmospheric plasma on soaking and germination of Hybanthus calceolaria seeds in order to accelerate these processes. Helium plasma jet produced by dielectric barrier discharge was used to treat H. calceolaria seeds with applications of 1, 5, and 10 minutes. The treated seeds were characterized considering their weight variation during soaking, changes in electrical conductivity, and pH. It was found that germination depended on the plasma application time. The treatment of H. calceolaria seeds with atmospheric plasma for 1 minute provided 3.5 times greater germination in comparison to untreated seeds. Atmospheric plasma technology obtained by dielectric barrier discharge had potential of being used as a germination accelerant in H. calceolaria seeds. The treatment of H. calceolaria seeds using atmospheric plasma for 1 minute favored germination.

ABSTRACT Fertilization is important for the optimization of plant growth and yield, which are necessary for agronomic activities. Soil fertilization should increase net earnings that depend on nutrient use efficiency. The aim of this study was to evaluate the agronomic efficiency of eggplant under different doses of potassium (K) and nitrogen (N). Four levels of K (0, 54, 108, and 216 kg ha-1) and four levels of N (0, 67, 134, and 268 kg ha-1) were applied weekly by fertigation. The highest plant and the largest stem diameter were found with 165-175 kg ha-1 of N. Leaf area was more influenced by N than by K. Isolated application of different K doses did not statistically influence height plant, stem diameter, or leaf dry matter. The agronomic efficiency of nitrogen is reduced with increasing levels of N and K.

ABSTRACT The apple tree depends on cross-pollination for adequate fruiting. The objective of this study was to evaluate the rate of parasitism by Varroa destructor mites and the infection rate of Nosema sp. in hives of Apis mellifera (Linnaeus) used in pollinating services in apple orchards in the municipality of Vacaria, Rio Grande do Sul state, Brazil. The study evaluated the sanitation of beehives before, during, and after apple orchard pollination. Natural parasitism by V. destructor and the presence of Nosema sp. spores were evaluated in hives from areas of forest and canola cultivation (in the 2014/2015 harvest), and from areas of forest and eucalyptus reforestation (2015/2016 harvest). In both harvests, the average rate of parasitism in the hives by V. destructor ranged from 3.0 to 6.7%. The levels of parasitism increased during the pollination period in hives from canola-cultivated areas (2014/2015 harvest), but not in those from the forest and eucalyptus reforestation areas. Spores of Nosema sp. were observed in hives in the 2014/2015 harvest but not in the 2015/2016 harvest. The levels of natural parasitism by V. destructor in A. mellifera hives used in pollination services remained low, and was within the levels reported for the southern region of Brazil. Additionally, the levels of Nosema sp. infection in the hives was low.

ABSTRACT The genetic variability within the crop species Ipomoea batatas is broad, hence, in order to support future breeding programs it is of the utmost importance that germplasm banks be created, conserved, and characterized. Therefore, the objective of this work was to rescue and evaluate the genetic divergence in sweet potato accessions collected in traditional communities of Vale do Ribeira Paulista. Sweet potato samples were collected from quilombos, indigenous villages, caiçaras communities, and small farms. The study was conducted between February 2013 and August 2014 in a randomized block design with three replications. Genetic material included 95 collected accessions and two commercial cultivars. Morphological characteristics of the accessions were evaluated and distances in the genetic distance matrix were estimated by means of multi-category variables, the data being subsequently clustered by the Tocher method. Analysis of the relative contribution of each characteristic and phenotypic correlation of descriptors was also performed. Results evidenced wide genetic diversity among the sweet potato accessions collected in Vale do Ribeira, which were not grouped according to the collection point. The descriptors that contributed more than 60% of genetic diversity included: leaf size, general leaf profile, immature leaf color, petiole pigmentation, predominant branch color, branch secondary color, stem length, cortical thickness, predominant periderm color, and periderm color intensity. Correlations between morphological descriptors was observed in 22.26% of the paired traits.

Abstract Gender studies on childhood imply the use of tools that, if elaborated in another country, they need to be translated and culturally adapted to Brazilian Portuguese. Objectives: To translate and adapt Cuban Spanish versions of the Encuesta de constatación y reflexión del sexismo en el ámbito escolar, and the Cuestionário auto-administrado de constatación y reflexión del sexismo en el ámbito escolar. Method: A qualitative and methodological study was developed with 37 experts (15 teachers of elementary school and 22 healthcare professionals on child health) from the Brazilian cities (Rio de Janeiro, Macaé, Itajaí, Porto Alegre) and Cuban (Habana). Results: Nine original questions of original tools were modified and adapted to the language, culture and elementary Brazilian education system. It was necessary to split the first tool into two separate parts (classroom and break) for facilitating its application by observers. Conclusion: Changes improved the deepness, consistency of observations among observers and introduced more specificity to final versions of tools for further applications on nursing and education studies.

OS LIMITES DA DEMOCRACIA: A LEGITIMIDADE DO PROTESTO NO BRASIL PARTICIPATIVO
Authors: Trindade Thiago Aparecido
Published: June 2018

O objetivo central deste estudo é analisar a legitimidade de formas disruptivas de ação coletiva em contexto de ampliação das oportunidades de participação institucionalizada no Brasil. Se, por um lado, a abertura de novos espaços participativos no sistema político pode ser considerada uma conquista importante dos movimentos populares, por outro, esse processo também pode contribuir para deslegitimar ações de protesto tradicionalmente mobilizadas por um conjunto de atores sociais com papel relevante na luta pela democracia. Metodologicamente, procedemos a uma revisão bibliográfica de temas e conceitos pertinentes à discussão e analisamos o material jornalístico. Além de apontar para a crescente tensão entre a abertura de novas arenas participativas no interior do Estado e a legitimidade do protesto, o texto também propõe uma reflexão sobre os estreitos limites dentro dos quais a ciência política brasileira tem pensado a noção de participação política.

LEGITIMAÇÃO SOCIAL EM TEXTOS LITERÁRIOS: STATUS E ETICIDADE NA DRAMATURGIA TRÁGICA OCIDENTAL
Authors: Luna Sandra
Published: June 2018

RESUMO: Este artigo revisita a dramaturgia trágica ocidental sob a perspectiva da legitimação social. Analisando períodos distintos dessa tradição teatral, evidencia-se como a relação entre status social e ethos heroico regula o universo dramático, modelando efeitos estéticos, éticos e políticos condizentes com as distintas “estruturas de sentimento” percebidas na história do drama. Da tragédia antiga ao drama moderno, a legitimação social, fundamentando a construção de caracteres, perfaz funções inerentes aos gêneros em que se inscrevem os textos.

Abstract The present study analyzed gastrointestinal helminth communities in 265 wild pigeons (Columba livia) living in the municipalities of São Paulo and Tatuí, state of São Paulo, Brazil, over a one-year period. The birds were caught next to grain storage warehouses and were necropsied. A total of 790 parasites comprising one nematode species and one cestode genus were recovered from 110 pigeons, thus yielding an overall prevalence of 41.5%, mean intensity of infection of 7.2 ± 1.6 (range 1-144) and discrepancy index of 0.855. Only 15 pigeons (5.7%) presented mixed infection. The helminths isolated from the birds were Ascaridia columbae (Ascaridiidae) and Raillietina sp. (Davaineidae). The birds’ weights differed according to sex but this did not influence the intensity of infection. The overall prevalence and intensity of infection did not differ between the sexes, but the prevalence was higher among the birds from Tatuí (47.8%). The gastrointestinal helminth community of C. livia was characterized in the two areas studied and parasite homogeneity was observed over the 12 months analyzed at both locations. These results make contributions to the current literature on health aspects of wild C. livia populations.

Clayey composite liners are appointed in modern landfills to isolate wastes from the environment and minimise the escape of contaminants that are affecting the groundwater and the subsoil. Enhanced compressibility and reduced permeability are considered favourable; however, the ameliorating liners are at risk of losing these properties and thus the ability to contain the contaminant due to changing pH and contaminant contents during the long course of service. This research investigated the change in the mechanical properties, namely, the compression index c c, permeability coefficient K and void ratio–effective stress curve e against log σ′ of bentonite clay treated with chemically modified sawdust contents and laced with various lead nitrate (Pb(NO3)2) concentrations. The optimum values were simultaneously achieved for c c and K, in the 10% sawdust of pH 10 design, with lead (Pb) concentration <150 cmol/kg soil, and in the 30% sawdust of pH 10 design, with lead concentration between 150 and 250 cmol/kg soil; therefore, these were the optimum designs with best returns in terms of the given geotechnical properties, for the given lead concentrations. In both acidic and alkaline states, K decreased in different lead concentrations, with the introduction of the 10–30% sawdust, which is the range of amount proposed in field applications.

Published: June 2018

This study compares the performance of two satellite-based solar radiation methodologies for estimating the solar resource available in South Africa. Data from thirteen stations distributed in six climatic regions were considered. More than one year of hourly values of global horizontal and beam normal irradiance were examined in the validation of the satellite-retrieved estimates at every location. The best satellite method resulted in an overall relative mean bias of 1.41% for the global horizontal irradiance corresponding to almost 3 Wm-2 and exhibited a relative mean bias of 2.85% for the beam normal irradiance estimation (about 7 Wm-2). This satellite-based method was implemented into a geographical information system module, which contained high-resolution terrain data and allowed the effect of the surrounding topography on the estimation of the available solar resource to be considered. These estimates can, therefore, be used as input data for further analysis or applications. As an example, maps of the potential output that could be expected in South Africa from photovoltaic systems were created.
The agglomeration of coal fines using wet microalgae biomass
Authors: Gaqa Sibongiseni Gloria , Watts Paul
Published: June 2018

South African coal generally contains a high percentage of non-carbon mineral matter, which necessitates processing to remove the bulk of the non-carbon material. Such processing results in the formation of some 60 million tons of discard coal and between four and eight million tons of very fine, unusable coal, called ultra-fines, each year. The objective of this study was to investigate factors that impact on the agglomeration of fine coal of <150 mm when using microalgae biomass as the sole binder. Mixtures of coal and wet microalgae biomass were prepared and pelletised. The proximate properties of the mixtures and coal were determined and the physical properties of the pellets measured, such as compression strength, water resistance and impact resistance. The results showed that pelletisation of Coalgae® is a promising technology for the recovery of coal fines. Moisture content, pressure and holding time influence the quality of the pellets. Compression resistance testing indicated that pellets made from the coal80%-algae20% (by weight) mixture were stronger than those made from the coal90%-algae10% (by weight) mixture. Pellets made from samples with ± 17% moisture content exhibited the strongest resistance, one of 1.8 kg/mm2 for the coal80%-algae20% mixture that was centrifuged after 24 hours. The water resistance index for all the pellets was lower than the recommended 95%, which was considered to put emphasis on handling, transportation and storage of the pellets.

Renewable energy technologies that can provide optimum and cost-effective energy savings to mitigate global warming, energy crisis and to achieve energy efficiency continue to be of paramount importance. The present study focused on identifying critical parameters such as the volume of hot water drawn off; ambient temperature; relative humidity; refrigerant temperatures at the inlet and outlet of the compressor and condenser; and deterministic quantities such as time used, power consumption and coefficient of performance (COP) as indicators to benchmark the performance of both the split and integrated types of air-source heat pump (ASHP) water heaters. The basis for analysis was on two predominant scenarios: first-hour heating rating and the heating cycle due to controlled volume of hot water drawn-off wherein both the integrated and split types ASHP water heaters experienced vapour compression refrigeration cycles. A data acquisition system was constructed and implemented to monitor the performance of both systems. The results obtained during summer season showed that, under the scenario of 150 L hot water withdrawal, the average COP of the systems was 3.18 and 2.85 for the split and integrated types respectively. The average power consumed was 1.29 (split type) and 0.85 kW (integrated type). The times of operation were 84 minutes (split type) and 138 minutes (integrated type).
Ni inclusión, ni equidad. Otras miradas para la formulación de políticas educativas con justicia social
Authors: Soler Martín Carolina , Martínez Pineda Maria Cristina , Peña Rodríguez Faustino
Published: June 2018

El presente artículo, resultado de investigación, expone algunas de las discusiones y tensiones que fundamentan el fracaso de las políticas de equidad y de inclusión enmarcadas en el cumplimiento del derecho a la educación. La mirada crítica se realiza especialmente a las estrategias de focalización, compensación, masificación, eficiencia, entre otras políticas, que no modifican las estructuras sociales desigualadoras y, por el contrario, perpetúan e incrementan las brechas sociales; a la vez que desconocen las luchas por el reconocimiento de las diferencias humanas en sus dimensiones culturales, políticas y económicas. En este orden, podría decirse que los vínculos entre educación con y para la justicia social están por construirse. El texto se estructura en dos apartados, el primero sitúa las problematizaciones vigentes en la política social y en las esferas culturales en relación con los procesos educativos; el segundo, presenta algunas iniciativas que buscan construir relaciones de proximidad entre educación y justicia social, desde la escuela, para avizorar elementos que contribuyan a configurar otros trazados de políticas sociales orientados a eliminar las injusticias sociales expresadas en exclusiones, desigualdades y discriminaciones por sexo, raza, color, género, condición social y económica, entre otras.
Experiencia de articulación del discurso de la memoria en un taller de relatos del terremoto y tsunami de 1960
Authors: Hualquimil Hermosilla Adriana , Abarca González Cristian
Published: June 2018

Este artículo describe la experiencia de reconstrucción de la memoria en torno al terremoto y tsunami de 1960, por parte de un grupo de sobrevivientes a este evento catastrófico. Para este estudio se ha utilizado metodología cualitativa, la que ha incluido la narración como ejercicio escritural, además de entrevistas en profundidad. Se efectuaron 10 talleres de narrativa y conversatorios con un grupo de 15 personas de Maullín, territorio costero del sur de Chile. Del análisis de los resultados se advierte que las representaciones de la memoria del evento de los miembros de la comunidad siguen patrones semánticos y simbólicos anclados en la tradición cristiana, la familia y la construcción de la identidad en torno al territorio. La ideación de tales formas constituye los marcos sociales que conforman la articulación de la narración testimonial.
