ABSTRACT The deleterious effects of salt stress can be mitigated by the use of beneficial microorganisms. The aims of this study were to evaluate whether coinoculation with Bradyrhizobium and Trichoderma asperelloides alleviates salt stress in cowpea. The experiment was conducted in a greenhouse using pots filled with sterile soil. Seeds were sown and inoculated with Bradyrhizobium or coinoculated with Bradyrhizobium and T. asperelloides. At 15 days after sowing (DAS), the nitrogen-free nutritive solution was supplemented with 50 or 100 mmol L-1 sodium chloride (NaCl) to induce salinity. Uninoculated plants and irrigated with solution without NaCl were used as absolute control. At 35 DAS, plants were collected, and nodules were excised for use in the determinations. The absolute controls did not show root nodules. Salt stress decreased plant biomass and growth, especially in cowpea inoculated with Bradyrhizobium. The stem diameter increased in cowpea coinoculated with Bradyrhizobium and T. asperelloides, mainly in plants subjected to salt stress at 100 mmol L-1 NaCl. Cowpea coinoculated with Bradyrhizobium and T. asperelloides maintained a higher content of free ammonia and organic compounds in its nodules even under salt stress. We concluded that the coinoculation of cowpea with Bradyrhizobium and T. asperelloides induces an increase in the concentration of organic solutes in the root nodules, especially when cowpeas are cultivated under salinity. Therefore, the use of coinoculation with Bradyrhizobium and T. asperelloides alleviates the negative effects of salt stress in cowpea.

Published: July 2019

ABSTRACT The objective of this study was to identify the spatial distribution of the physiological quality of soybean seeds during storage from a production field of 39 hectares using geostatistical techniques in the 2012/2013 harvest. Seeds were sampled at geo-referenced points for the determination of physiological quality and spatial dependence analysis. The results were submitted to analysis of descriptive statistics, Pearson's linear correlation and geostatistics. The grid of one point per hectare and a georeferenced sampling mesh with spacing of 100 meters between points was efficient in the evaluation of the spatial variability. It was verified the existence of a negative correlation between the variable protein content and bed bug attack and a significant correlation between the intensity of bed bug damage and the protein content with the variables related to seed quality. Physiological quality is not uniform, particularly in relation to vigor, providing better diagnosis through interpolation maps. Precision agriculture, coupled with the monitoring of seed quality during storage, indicated spatial variability of quality from harvest to the end of storage. Areas with high rates of bedbug and unit damage presented low quality physiology and reduced protein levels. The geostatistics allows to determine the spatial distribution of the physiological quality of soybean seeds in the area of seed production, facilitating the decision making, regarding the areas to be harvested.

ABSTRACT Small variations of relief may change drainage and runoff and hence promote the formation of sandy surface horizons and hardened subsurface horizons (fragipans and/or duripans) in Coastal Tablelands soils. This study aimed to investigate the pedogenesis on Coastal Tablelands area with low range altimetry in Paraíba state; secondly, we also sought to contribute to the improvement of the Brazilian Soil Classification System (BSCS). Four soil profiles ware described and collected to be submitted to routine physical and chemical analysis, determination of Fe, Al and Si extracted by sulfuric acid digestion, sodium citrate-bicarbonate-dithionite and acid ammonium oxalate, sodium pyrophosphate, and mineralogical analysis in the sand and clay fractions by X-ray diffractometry. Optical density of the oxalate extract (ODOE) was also determined; the results were statistically evaluated using the R software. Microrelief variations conditioning differentiated water flows, along with the sandy texture of the surface horizons (A and E) and the lower coarse sand/fine sand ratio in the subsurface horizon, seem to promote clay accumulation in depth in the Spodosols developed on Coastal Tablelands environments. For this soils, the argilluvic (argissólico) character at the subgroup level of the BSCS should be incorporated. In addition, Al amorphous mineral phases and/or poorly crystalline play an important role in the formation of strongly cemented horizons (duripans) of the Spodosols, as also reported by other authors. Finally, the ODOE showed to be an efficient indicator of soils under podzolization process, being possible its use as a taxonomic criterion for classification of Spodosols by the BSCS.

ABSTRACT Measures of the apparent electrical conductivity (ECa) of soil are used in many studies as indicators of spatial variability in physicochemical characteristics of production fields. Based on these measures, management zones (MZs) are delineated to improve agricultural management. However, these measures include outliers. The presence or incorrect identification and exclusion of outliers affect the variogram function and result in unreliable parameter estimates. Thus, the aim of this study was to model ECa data with outliers using methods based on robust approximation theory and model-based geostatistics to delineate MZs. Robust estimators developed by Cressie-Hawkins, Genton and MAD Dowd were tested. The Cressie-Hawkins semivariance estimator was selected, followed by the semivariogram cubic fit using Akaike information criterion (AIC). The robust kriging with an external drift plug-in was applied to fitted estimates, and the fuzzy k-means classifier was applied to the resulting ECa kriging map. Models with multiple MZs were evaluated using fuzzy k-means, and a map with two MZs was selected based on the fuzzy performance index (FPI), modified partition entropy (MPE) and Fukuyama-Sugeno and Xie-Beni indices. The defined MZs were validated based on differences between the ECa means using mixed linear models. The independent errors model was chosen for validation based on its AIC value. Thus, the results demonstrate that it is possible to delineate an MZ map without outlier exclusion, evidencing the efficacy of this methodology.

ABSTRACT In the search for homogeneous planting density and satisfactory results in soybean development and yield, the treatment of seeds can be carried out using a combination of chemical fungicides, growth stimulators, and other biological agents. The objective of this study is to evaluate the effect of chemical and biological inputs for soybean seed treatment on crop development and yield. Experiments were carried out in the 2010/2011 growing season in three municipalities of Rio Grande do Sul using the following treatments: fungicide fludioxonil, Trichoderma spp., fludioxonil + Trichoderma spp., fludioxonil + Trichoderma spp. + the growth stimulator Biozyme®, and a control (untreated). The total number of pods in treatment with Trichoderma spp. and the other treatments were up to 77% higher than that of the control. The grain yield of treatments with fludioxonil, fludioxonil + Trichoderma spp., and fludioxonil + Trichoderma spp. + Biozyme® was up to 14% higher than that of the control. These results indicate that fludioxonil combined with the fungus Trichoderma spp. and Biozyme® is indicated for treating soybean seeds and increases crop development and grain yield.

ABSTRACT Ornamental plants are all plants grown for their beauty and are commonly used in gardening and landscaping. The colorful fruits and varied foliage colors that typify ornamental peppers provide a vibrant garden display that rivals other ornamental plants. This study aimed to evaluate the potential ornamental use of eight pepper accessions, Capsicum annuum, from the Capsicum Germplasm Bank of the Universidade Federal do Piauí, using qualitative and quantitative descriptors. The experiment was carried out in a greenhouse at the Department of Plant Science, Centre of Agricultural Sciences of Universidade Federal do Piauí, where the accessions were evaluated through a completely randomized design, with eight replicates, one plant per plot, and characterized based on 35 descriptors, 23 of which were qualitative and 12 quantitative. Data on quantitative descriptors were submitted to univariate analysis of variance, followed by Scott-Knott clustering test at 5% probability. Data on qualitative multicategorical descriptors were considered based on observations of statistical mode. The eight accessions evaluated have ornamental potential and are within the standards established by the Instituto Brasileiro de Floricultura. The accessions BAGC 98, 100, 203, 207, 224, and 236 accessions are suitable for cultivation in pots, while BAGC 220 is suitable for garden cultivation. BAGC 199 is the most promising accession because it supports all quality criteria required for size, foliage, flowers, and fruit proposed by the Veiling Holambra Cooperative.

Published: July 2019

ABSTRACT The main propagation mode of dovyalis is by seeds, what makes important to determine the ideal moment of fruit harvest. This study aimed to evaluate the physiological seed quality and harvest time of dovyalis fruits. To determine the fruit physical attributes, they were visually classified into five classes, according to the maturity stages, based on the external color of the exocarp: stage 1: green fruit; stage 2: yellowish-green; stage 3: yellowish-brown; stage 4: brown; stage 5: intense brown. The seed extraction to evaluate the physiological quality was based on the seed water content, germination percentage, germination speed index and determination of the dry biomass of the shoot, root and seedlings originated from these seeds. The experimental design was completely randomized, containing 25 seeds per treatment and 4 replicates. The fruit color during ripening varies from green to intense brown. The fruits reach their largest size and fresh biomass accumulation in the stage 4, with the brown exocarp color represented in the Munsell chart by 2.5YR 3/4. The removal of seeds for propagation should occur from the stage 2 (2.5GY 5/8), when the fruits have a yellowish-green color, although no statistical variation is observed in the number of seeds during maturation.

ABSTRACT The use of crop models that integrate soil, climate, cultivar and management information may broaden the understanding of the interactions between soybean cropping system and local climate variability. This study aimed to analyze the potentiality of soybean in an Amazonian production environment, as well as to determine an optimal sowing window via agrometeorological modeling. A crop model was programmed to simulate the soybean yield for 18 sowing dates, obtained along 33 years of climatic data, under attainable and potential conditions. The simulated potential of soybean yield ranged from 3,785 kg ha-1 to 5,114 kg ha-1, owing to the local energy availability, whereas the average attainable yield ranged from 557 kg ha-1 to 4,700 kg ha-1, mainly because of the soil moisture conditions. The smallest difference between the potential and attainable yields was observed in the sowing dates from 01-Jan to 15-Feb. For this window, the probability of obtaining yields above 3,500 kg ha-1 was higher than 90 %.

Published: July 2019

ABSTRACT Basil is an aromatic herb that stands out for its economic importance. It is consumed in natura and used to obtain essential oil. The cultivation of this species in several regions of the world has allowed variations by natural crosses and euploidy, leading to the wide genetic variability found nowadays. Considering the importance of this species, we aimed to analyze the genetic diversity of 27 basil genotypes using ISSR molecular markers. Fourteen primers were employed for DNA amplification, resulting in 86% polymorphism. Based on the Jaccard’s dissimilarity index, the highest index (0.80) was observed between the individuals BAS001 and BAS012, while the lowest index (0.18) was detected between the genotypes BAS014 and BAS015. The genetic similarity among individuals was calculated, forming four distinct clusters. Most individuals (40.7%) were allocated in cluster I. The polymorphic information content (PIC) (0.89) indicated considerable levels of genetic diversity among genotypes. In this sense, the ISSR markers were efficient in the detection of polymorphisms between the accessions, suggesting the genetic variability of the collection. This result demonstrates the importance of the use of molecular markers and the advantages that this information provides to the breeding of the species.

Published: July 2019

ABSTRACT The correct use of hydrogels in some situations can increase seedling survival rates, plant growth, and the water-retention capacity of the growing medium. A technique for the production of a nanocomposite hydrogel using calcium montmorillonite (NC-MMt) was recently developed. However, additional research is necessary in order to validate this innovative input, particularly for the production of vegetable crops seedlings. In this context, the main objective of the present study was to evaluate the growth and development of seedlings, tomato hybrid ‘BRS Nagai’, in substrates containing different amendments of hydrogel NC-MMt. The trial was conducted in a 3x3 factorial arranged in a complete randomized blocks design, with three replications. Three substrates (peat moss, pine bark, and coconut peat) corresponded to the first factor and three rates of the NC-MMt hydrogel (0%= R1, 1.5%= R2 and 2.0%= R3, on a w/w basis) corresponded to the second factor. Each plot was composed of 16 plants that were assessed after three weeks. Overall, peat moss-based and pine bark-based substrates resulted in higher values for most of the analyzed traits: plant emergency percentage, plant height, stem diameter, leaf area, plant height/shoot dry weight ratio, root dry weight, shoot dry weight/root dry weight ratio and the Dickinson Quality Index. Rates of NC-MMt hydrogel displayed significant responses only to root superficial area and root volume. NC-MMt hydrogel amendment (mainly 1.5%) combined with specific substrates (mainly peat moss-based substrate) was able to improve the growth of ‘BRS Nagai’ tomato seedlings, with no observed toxic effects.

ABSTRACT The genetic diversity of pepper genotypes is usually evaluated based on morphological and molecular descriptors. However, studies using biochemical descriptors of peppers are still incipient. Thus, the objective of this study was identify biochemical descriptors of Capsicum spp. with antioxidant action, most responsive to the selection of superior genotypes, and evaluate the correlation between concentrations of the parameters using principal components analysis. The experiment was conducted in the city of Cáceres, southwest Mato Grosso, Brazil. Seventy-eight pepper accessions from the Active Germplasm Bank of UNEMAT were planted in randomized block design. The harvested fruits were immersed in liquid nitrogen for two minutes, and the following biochemical analyses were performed: titratable acidity, ascorbic acid, total phenols, flavonoids, anthocyanins, carotenoids, chlorophyll a, chlorophyll b, and antioxidant activity. Biochemical descriptors that best estimated the genetic variability of the accessions were flavonoids, total phenols, chlorophyll a, and ascorbic acid. Chlorophyll a and chlorophyll b were the compounds that showed the highest degree of correlation. Except chlorophyll a with ascorbic acid, all other vectors showed correlation ranging from moderate to strong.

ABSTRACT Salinity of soil in arid and semiarid regions is a problem that affects the production and quality of fruit. That’s while we evaluated grafting on watermelon plants as an alternative to reduce the salinity effects. The experimental design was of randomized blocks, three treatments (cultivars Sangria, Summer Flavor 800 and Summer Flavor 840) with three repetitions. The cultivars were evaluated in grafted and ungrafted condition. The rootstock used for grafting was the interspecific hybrid Strong Tosa (C. maxima x C. moschata). In average terms for the three cultivars, grafting increased commercial production, weight, length and diameter of fruits in 160.5%, 36.5%, 12.0% and 7.5%, respectively. Sangria presented the best answer in production with 57.1 t ha-1, weight 5.8 kg, length 35.0 cm and diameter 17.8 cm of fruits. Also, grafting favored in 6.3% the luminosity and reduced 6.4% Hue angle. Summer Flavor 840 showed the best result in luminosity with 48.3 and hue angle 26.4°. Firmness, °Brix and lycopene content were not modified by grafting. Grafting represents an alternative for watermelon production in saline soils, improving yield and quality of the fruits.

ABSTRACT Constructed wetlands might be an alternative for communities away from urban centers and not served by a domestic wastewater treatment system. The purpose of this study was to provide instructions for the implementation of subsurface flow constructed wetland systems. To that end, we gathered information regarding the construction aspect, plants, and operational parameters used in systems which already operate in the country and the respective efficiency of these sets after previous treatment. The system in real scale proposed by Oliveira et al. (2005) was prominent among those that presented the highest efficiency. It was preceded by upflow anaerobic reactor built in brick, with macrophyte of the Typha genre, crushed stone at the entry and exit of the system, and sand in its intermediate portion. It required 1.04 m² surface area per inhabitant in humid temperate climate and hot summer, 1.71 m³ d-1 flow, and one-day hydraulic detention. The considerations presented here might help the construction of this kind of system, regarding dimensional and operational criteria.

ABSTRACT Aquatic ecosystems are under severe anthropogenic modifications. Thus, the dependent biological communities in these environments are also changed. The objective of this study was to investigate the effects of urban development in a highly impacted ecosystem. We selected 15 sampling points along the stream Ribeirão Vermelho, in which were sampled benthic macroinvertebrates and assessed the water and habitat diversity. It was found an impact gradient, with some the reference points classified as natural and others as impacted. There was a significant difference in all biological indicators used. The total number of taxa, the wealth of Diptera, the taxa Ephemeroptera, Plecoptera and Trichoptera, and the diversity indices, the Water Quality Indices, and the percentage of herbivores crushers and predators were significantly higher in points classified as natural and changed. The relative abundances of collectors, filter feeding, chironomids and parasites were significantly lower in sites classified as natural in relation to impacted ones. The metrics of the macroinvertebrate community benthic and Habitat Diversity Protocol were influenced by environmental degradation, being a useful tool for planning and development actions for the preservation of watersheds and the prioritization of high-value transmission systems for protection and rehabilitation of aquatic ecosystems

SUMMARY The aim of this study was to evaluate the economic viability of the inclusion of urea in the ration provided to feedlot lambs. Twenty-four non-castrated male lambs, crossbred Dorper, with 2-5 months of age and a body weight (BW) of 25.0 ± 4.3 kg were used. A completely randomized design with four treatments and six replicates was adopted, in which the treatments were urea levels of 0.0, 0.5, 1.0 and 1.5% in the ration, on a dry matter (DM) basis. Lambs were fed ad libitum for 56 days and slaughtered at a BW of37.9 ± 5.1 kg. The analyzed economic indexes were the cost of the rations, cost of marginal factor (CMF), revenue of marginal factor (RMF), net revenue (NR) and benefit: cost ratio (BCR). The ration without urea presented the highest cost (0.30 US$/kg DM) and the ration with 1.0% DM of urea had the lowest cost (0.23 US$/kg DM). The CMF had a quadratic response to the urea level, reaching the lowest value (0.28 US$/day) with the addition of 0.9 to 1.0% DM of urea. The lowest and the highest NR values were obtained from the rations without and with 1.5% DM of urea, respectively (0.26 and 0.34 US$/day). The ration without urea had a worse BCR (1.74), whereas the ration with 1.0% DM of urea resulted in a better BCR (2.09). A better economic return for lambs finishing in feedlots is obtained with rations containing 1.0 to 1.5% DM of urea.

Resumo Na chamada era da informação, a temática das tecnologias digitais se consolida no discurso pedagógico e nas pesquisas em educação, pelos quais perpassa a denúncia da necessidade de paradigmas educacionais que dialoguem com as inovações tecnológicas de nosso tempo. Assim, numerosos investimentos, públicos e privados, vêm sendo feitos buscando viabilizar a incorporação das tecnologias digitais no cotidiano escolar. Contudo, percebe-se uma lacuna quanto às indagações sobre o que se entende por tecnologia no âmbito educacional e sobre de que maneira esse entendimento influencia o campo. Posto isso, este trabalho propõe identificar e analisar as percepções de tecnologia que perpassam o discurso das políticas públicas em educação no Brasil. Para tanto, é utilizada a análise crítica do discurso, aplicada aos documentos das políticas públicas em educação que deliberam parâmetros e diretrizes para a incorporação das tecnologias digitais no âmbito escolar. Especificamente, opta-se pela análise do Plano Nacional de Educação 2014-2024 e do Programa de Inovação Educação Conectada, política mais recente no que tange à temática. Propõem-se duas categorias de análise sobre as percepções de tecnologia: artefato técnico e artefato sociocultural. Considera-se, por fim, que, embora haja apontamentos em direção a perspectivas socioculturais quanto à tecnologia no âmbito educacional, a percepção preponderante se relaciona mais fortemente aos aspectos da tecnologia como artefato técnico.

ABSTRACT Objective: To relate the level of functional health literacy with adherence and barriers to non-adherence, rehospitalization, readmission and death in patients with heart failure. Method: A cross-sectional, analytical study with patients admitted to the emergency room with a diagnosis of heart failure. Literacy was assessed by the Newest Vital Sign. Patient adherence to medication treatment and barriers to non-compliance were assessed 90 days after discharge by the Morisky-Green test and the Brief Medical Questionnaire, respectively. Results: 100 patients participated in the study. The mean age was 63.3 years (± 15.2), with a predominance of white women. Medication adherence was low in 41.1% of participants, of which 55.9% presented inadequate literacy. Re-hospitalization and death were present in patients with inadequate literacy (p<0.001). Conclusion: The low level of literacy was directly related to lower adherence and the presence of barriers to medication adherence, as well as higher rehospitalization rates and death.

ABSTRACT Objective: To identify health alterations in nursing students after a year from admission to a nursing undergraduate course. Method: A longitudinal prospective study with a quantitative approach was carried out in 2016 with first-year nursing students from two universities in the state of São Paulo. The following instruments were applied at the beginning and the end of the first school year: an instrument for Assessment of Stress in Nursing Students, the Center for Epidemiologic Studies Depression Scale, and the Pittsburgh Sleep Quality Index. The ANOVA test for mixed models was used for analysis. Results: The sample was made up of 117 students in March and 100 students in December. A significant increase in stress in all dimensions of the instrument, a reduction in the duration and subjective quality of sleep, and an increase in general stress and depressive symptoms were observed. Conclusion: The nursing academic environment presents the potential for students to become ill. Institutions should rethink their curricular elements, promote resilience, and create spaces to promote students’ health.

Published: July 2019

Abstract The present study evaluated the feasibility of the use of grinding dust (GD), a waste generated in the clutch disc finishing process, as a retardant additive in cementitious matrices. For this, the waste was added in contents of 5%, 10% and 15%, relative to the cement weight, and the setting time was determined by the Vicat method. In addition, the influence of this material on rheology (flow table, squeeze-flow and rotational rheometry) and on the physical-mechanical properties of the hardened matrices was analyzed. The results indicated an increase in setting time and a reduction in the fluidity of the mortars as a function of the addition of GD and the best results for the hardened state properties were verified for the cementitious matrices containing a 5% addition. Therefore, it was observed that GD is effective in retarding the setting time, presenting great potential for use in civil construction, without impairing its properties.

Abstract Aim Avicennia schaeuriana is one of the six species that composes the mangrove forests of Brazil and form mangrove fringes along waterways. The mangrove-roots of the A. schaeuriana act as one of the microhabitats used by the invertebrate biodiversity of the estuarine ecosystem. The present note aimed to inventory the malacofauna associated with roots of Avicennia schaueriana of the hypersaline and inverse estuary, highlighting variations in abundance and diversity along a salinity gradient and different seasonal periods. Methods Three sampling stations were delineated along the course of the estuary. At each station 3 transects of 10 meters were placed, and for each of them 3 sample points were selected, and at each point 3 samples of roots of A. schaueriana were obtained. A total of 108 samples were stored in plastic bags containing 4% formaldehyde and subsequently passed through a screening process, with identification of the associated specimens with the lowest possible taxonomic level. Results A total of 171 specimens was recorded, belonging to 10 species, 7 families, and 9 genera of the Bivalvia and Gastropoda classes. The abundance of the specimens differed between the seasonal periods analyzed. Conclusions The highest species richness and abundance of organisms in the rainy period allows inferences about the importance of the estuarine water cycle in regulating the biodiversity of these environments. Thus, the importance of the maintenance and protection of the mangrove forests composed of A. schaueriana, as well as the need for more in-depth studies becomes evident.

Resumo: Este texto tem como propósito elucidar a existência de um problema histórico e historiográfico que envolve a figura de Thomas Paine e em decorrência do qual sua importância e lugar na história não têm recebido o devido reconhecimento. Para demonstrar os porquês da existência do “problema Paine”, faz-se mister apresentar uma breve exposição da vida e obra do autor, um levantamento e avaliação das questões que envolvem suas biografias, as publicações de suas obras completas, e os debates sobre seu legado e sua fortuna historiográfica. Nossa abordagem enfatiza três textos de Paine que, embora consideremos fundamentais no estudo das revoluções democráticas do final dos Setecentos, têm sido pouco ou mal explorados pela historiografia.
Ojos de mosca. Los peronistas, la política y los lugares de la acción (1945-1955)
Authors: Rogé Mariana Garzón
Published: July 2019

Resumen: El artículo ofrece una mirada sobre los estudios dedicados a la política de los peronistas entre 1945 y 1955. Advierte que los actores han dejado de ser caracterizados como “pasivos” para ser imaginados como “agentes” que se oponen a una “estructura”. Esa dualidad se muestra problemática al caracterizar el conjunto de actividades que diversos peronistas producían como políticas en situación. El artículo, a la luz del giro pragmático, propone como horizonte la descripción de la acción que desplegaban actores competentes sumidos en contextos plurales no evidentes. En ese registro de la acción situada se tornan observables instancias concretas de creación y transformación del peronismo sin tener que apelar a fórmulas definidas por su indefinición frecuentes en importante bibliografía sobre el tema.

Published: July 2019

The growth in demand for power generation and energy from alternative fuels at low cost and friendly to the natural environment is increasing. This study used waste plastic pyrolysis oil (WPPO) and ethanol to apply direct blending of conventional diesel, WPPO and ethanol with 2-ethyl hexyl nitrate (EHN). The purpose was to improve the combustion and performance characteristics of the WPPO blends. The EHN has the potential to reduce emissions of carbon dioxide, carbon monoxide, unburnt hydrocarbon, oxides of nitrogen and particulate matter. Ethanol improves viscosity, miscibility, and the oxygen content of WPPO. Five mixing ratios were selected. The mixing ratio with EHN was based on total quantity of blended fuel at 0.01%. At 50% engine load, the brake specific fuel consumption was 0.043 g/kWh compared with CD at 0.04 g/kWh. The blend 90/WPPO5/E5 had the highest value of 14% for brake thermal efficiency, while on NOX emissions three blends 90/WPPO5/E5, 80/WPPO10/E10, 70/WPPO15/E15, had the lowest values of 384 ppm, 395 ppm, 414 ppm, compared with CD fuel at 424 ppm. The implication was that ethanol and WPPO blends can be used in diesel engine power generators as an alternative fuel with modification, as their respective densities of 792 kg/m3 and 825 kg/m3 are close to CD fuel’s at 845 kg/m3. Additionally, these combinations with EHN reduced emissions more than earlier thought and improved engine performance, equalling that of conventional diesel fuel.

Optimisation and diversification of South Africa’s energy generation mix is fundamental to meeting its developmental goals and enhancing the crucially important security of supply. South Africa should investigate means to diversify its generating capacity. With the growing demand, South Africa has reached a point where other methods of power generation need to be considered and implemented. This study gives a detailed description of the South African energy supply mix, its evolvement in the past 25 years, and assesses how South Africa fares in comparison with other countries such as its BRICS companions (Brazil, Russia, India, and China) and in the Organisation for Economic Co-operation and Development (OECD), in terms of its current and future energy mix. It was found that the total primary energy supply (TPES) share of non-OECD countries is becoming more prominent, with China, India, and Russia being significant contributors. The OECD’s ratio of universal TPES decreased from 1990 to 2015. There is a heavy reliance on fossil fuels in the BRICS countries, which appeals to appropriate policies to influence and guide the transition from the current fossil fuel-dominated energy supply mix to one that follows international trends but, most of all, appreciates its specific geographic position and natural resources.
Potentials of locally manufactured wound-field flux switching wind generator in South Africa
Authors: Akuru Udochukwu B. , Kamper Maarten J.
Published: July 2019

The China-based monopoly of high-energy permanent magnet materials used in modern wind generators impact the economic viability and local content value of most wind turbines installed in South Africa, especially large installations. It is possible to design with less expensive excitation technologies using locally-sourced wound-field electromagnets, which might promote local content. This study involves the optimum design performance comparison of the wound-field flux switching machine (WF-FSM) technology based on two variants – Design I and II (D-I and D-II) – the difference being in the arrangement of their DC wound-field coils. The machines are evaluated using finite element analyses (FEA) with optimum performance emphasised on design parameters such as torque density, efficiency and power factor. The selected design targets are meant to improve the performance to cost fidelity of the proposed wind generator variants. In 2D FEA, D-II can produce up to 18.8% higher torque density (kNm/m3) and 17.1% lesser loss per active volume (kW/m3) than D-I. In 3D FEA, the torque density of D-II remains higher at 10.6%, but its loss per active volume increases by 15% compared to D-I. The discrepancy observed in 2D and 3D FEA is due to an underestimation of the end-winding effects in D-II. The power factor of D-II is higher than D-I, both in 2D and 3D FEA, which may translate to lower kVA ratings and inverter costs. A higher total active mass ensues for the studied WF-FSMs than a conventional direct-drive PMSG, but avoiding rare earth PMs translate to significantly lower costs.

Authors: Mesa Rivera Sara Catalina , Villa Tamayo María Alejandra
Published: July 2019

En el presente artículo se aborda el tema del medio ambiente desde la perspectiva de Japón; un país que ha afrontado difíciles situaciones ambientales, pero que hoy en día se consolida como un país capaz de configurar estrategias sostenibles para el presente y el futuro de la población mundial. En este artículo se realiza un análisis de las políticas ambientales impulsadas por el gobierno japonés, las cuales han generado un alto impacto, tanto para sus ciudadanos, como para las industrias nacionales. A su vez, se exponen dos multinacionales japonesas, que han implementado múltiples campañas y tácticas para promover la protección y preservación del medio ambiente. Por último, se hace una reflexión sobre cómo Japón, un país con un alto desarrollo tecnológico, económico y social, ha podido sacar adelante un proyecto ambiental de tal magnitud que lo ha convertido en el país menos contaminante del mundo, aspecto que debe servir de ejemplo a la comunidad internacional.
Legítima defensa de animales
Authors: Greco Luís
Published: July 2019

If we recognize that animals have rights, even minimal and rudimentary as the right to not to be killed without an acceptable reason or the right to live without constant or repetitive pain (§ 17 Animal Protection Law), then the consequence is that they would be covered by the right to self­defense. Such rights would configure the attacked subjective right, which is exercised by humans instead of animals and they do so in their interest based on a legitimate third party’s defense. The legitimate defense in favor of animals is, however, less extensive than the one which is carried out in favor of a human being, according to the thesis I defend in this article.
Prostitución: ¿qué castigar? Trabajadoras, burdeles, rufianes y clientes
Authors: Llobet Anglí Mariona
Published: July 2019

The present investigation analyzes the legal treatment of prostitution and its form of punishment when it is done coercively. From a Criminal Law perspective, there is some debate on whether it is necessary to expand the field of potential authors who, in some way, obtain economic or social benefits from prostitution:. Among the first are, on the one hand, the non-coercive pimps, basically, the owners of brothels and hostess clubs and ruffians, and, on the other hand, those who practice prostitution. Among the second are the customers. This article looks at the different models that speak of the punishment of this practice and exposes its characteristics, and then goes on to develop its central objective that to analyze the legitimacy of such models from a criminal perspective, which implies to investigate the basis of the punishment of the behaviors whose criminalization is defended.
El archivo y el testigo. Un análisis de la relación entre memoria y justicia a partir del caso colombiano
Authors: Benavides Vanegas Farid Samir
Published: July 2019

In memory studies and in the field of transitional justice, the story of the victims is usually seen as relevant. It is usually assumed that what is said by the victims has an absolute value of truth and cannot be controverted, otherwise we would be attacking their dignity. And, next to this, it is maintained that everything held by the perpetrators is false, and therefore we cannot believe absolutely in what they tell. But we have to take into account that neither perpetrator nor victims are witnesses, but, from a legal point of view, they are active parties in that social relationship we call crime. In this text, I want to discuss the relationship between the witness and the archive and for that I use the Colombian case as a case study. Initially I analyze the question of memory and later I analyze the relationships between truth and memory. With this text, I intend to contribute to the studies of transitional justice that take for granted, without further analysis, the validity of the documentary contributions or the stories of the victims and the witnesses. It is not a mere theoretical pretension, since it depends on the elaboration of truth criteria for both the criminal justice system and the Truth Commissions.
La legítima defensa en Derecho Internacional Penal: análisis de sus elementos con particular referencia a los crímenes de guerra
Authors: Servín Rodríguez Christopher A.
Published: July 2019

The present investigation analyzes the elements of self-defense in International Criminal Law with particular reference to war crimes. In that regard, article 31.1, subsection C, of the Rome Statute is examined to demonstrate that self-defense in relation with crimes against humanity, genocide and aggression protects the person who exercise it and a third person, but in relation with war crimes, its protection also covers, without precedent, property. Nevertheless, this could be contrary to International Humanitarian Law.

RNA-chromatin interactions represent an important aspect of transcriptional regulation of genes and transposable elements. However, analyses of chromatin-associated RNAs (caRNA) are often limited to one caRNA at a time. Here, we describe the iMARGI (in situ Mapping of RNA-Genome Interactome) technique used to discover caRNAs and reveal their respective genomic interaction loci. iMARGI starts with in situ crosslinking and genome fragmentation, followed by converting each proximal RNA-DNA pair into an RNA-linker-DNA chimeric sequence. These chimeric sequences are subsequently converted into a sequencing library suitable for paired-end sequencing. A standardized bioinformatic software package called iMARGI-Dockeris provided to decode the pairedend sequencing data into caRNA-DNA interactions. Compared to its predecessor MARGI, in iMARGI the number of input cells is 3-5 million, which is reduced by 100-fold, experimental time is reduced, clear checkpoints have been established. It takes a few hours a day and a total of 8 days to complete the construction of an iMARGI sequencing library and one day to carry out data processing with iMARGI-Docker.

Published: July 2019

In this paper, a set of Dombi power partitioned Heronian mean operators of q-rung orthopair fuzzy numbers (qROFNs) are presented and a multiple attribute group decision making (MAGDM) method based on them is proposed. Firstly, the operational rules of qROFNs based on the Dombi t-conorm and t-norm are introduced. According to these rules, a q-rung orthopair fuzzy Dombi partitioned Heronian Mean operator and its weighted form are then established. To reduce the negative effect of unreasonable attribute values on aggregation result in these operators, a q-rung orthopair fuzzy Dombi power partitioned Heronian mean operator and its weighted form are constructed via combining them with the power average operator of qROFNs. On the basis of the constructed operators, a method to solve the MAGDM problems based qROFNs is designed. Finally, a practical example, a set of experiments, and comparisons are reported to demonstrate the feasibility and effectiveness of the proposed method. The demonstration results show that the method is feasible, effective, and flexible, which has satisfying expressiveness and concurrently can consider the interrelationships between different attributes comprehensively and reduce the negative influence of biased attribute values.
