Abstract (Introduction): Vinasse is generated as a residue in the production of ethanol by fermentation-distillation of molasses/sugar cane juice, at a rate of 13 L/L of ethanol. It is an acid liquid, brown in color, characterized by high mineralization and Chemical Oxygen Demand (COD) values of up to 150 000 mg/L, being highly polluting. (Objective): The objective of this research was to evaluate a vinasse treatment process with hydrogen peroxide as a source of hydroxyl radicals at laboratory scale. (Methodology): The vinasse samples, from different distilleries in the province of Tucumán, were characterized following standardized techniques of Standard Methods. The oxidation tests were carried out with different peroxide/vinasses ratios, in a semi-batch reactor, under ambient conditions, measuring COD as an indicator parameter of the treatment. (Results): After 5 days, an 85 % decrease in COD and an increase in the Biodegradability Index were achieved. The kinetics of the oxidative reaction was first order with respect to COD, with an apparent rate constant of 0.3694 1/day. (Conclusions): Although the COD values allowed by local regulations (250 mg/L) were not reached, the proposed treatment is encouraging due to its simplicity, representing a potential option to the environmental challenge represented by vinaze in Latin America.

Es un efluente líquido, ácido caracterizado por una elevada mineralización y valores de demanda química de oxígeno (DQO) de hasta 150 000 mg/L, siendo altamente contaminante. (Objetivo): Ealuar un proceso de tratamiento de vinazas con peróxido de hidrógeno, como fuente de radicales hidroxilos, en escala laboratorio. (Metodología): Las muestras de vinazas, de destilerías de la provincia de Tucumán, se caracterizaron según técnicas normalizadas de Standard Methods. Los ensayos de oxidación se realizaron con distintas relaciones de peróxido/vinaza, en un reactor semibatch, en condiciones ambientales, midiendo DQO como parámetro indicador del tratamiento. (Resultados): Al cabo de cinco días se logró una disminución de DQO del 85 % y un aumento del Índice de Biodegradabilidad. La cinética de la reacción oxidativa fue de primer orden respecto de DQO, con una constante aparente de velocidad de 0.3694 1/día. (Conclusiones): Si bien no se lograron los valores de DQO permitidos por la normativa local (250 mg/L), el tratamiento propuesto es alentador por su simpleza, representando una opción potencial al desafío ambiental que representan las vinazas en América Latina.

ABSTRACT Moringa oleifera Lam. is an arboreal forest species of great economic potential, adapted to the climatic conditions of the Brazilian semi-arid region, whose multiplication is mainly by seeds. Rapid viability and vigor tests help in the choice of lots. Thus, the objective of this study was to assess the efficiency of the pH of exudate and primary root protrusion tests in the evaluation of viability and vigor, respectively. Two seed lots were initially evaluated for moisture content, germination, first count, germination speed index, seedling length, seedling dry mass and electrical conductivity. For the pH of exudate test, phenolphthalein (1%) and sodium carbonate (2 and 4 g L-1) solutions were prepared, with three soaking periods (1, 3 and 5 h) and three temperatures (25, 30 and 35 °C). Exudate solution in strong to light pink color indicated viable seeds, whereas very light pink color to colorless indicated non-viable seeds. The primary root protrusion test was performed under 25, 30 and 35 °C, evaluating the primary root protrusion of at least 2 mm, every 12 h until 196 h. The experimental design was completely randomized, with four replicates. pH of exudate test with 1 h of soaking at 25 or 30 °C with 2 g L-1 sodium carbonate solution was promising, but further studies are needed before it is indicated as routine use for the species. Primary root protrusion test is efficient and can be conducted at 35 °C with evaluation after 48 h.

ABSTRACT Chia (Salvia hispanica L.) seeds have attracted great economic interest for their high levels of linoleic and α-linolenic acids. In Brazil, there is a lack of studies on the agronomic characteristics and physiological quality of chia, necessitating research on germination processes and strategies to enhance yield under field conditions. There are no studies assessing the development of seeds with different coat colors in the presence of fungicides. This study aimed to assess the physiological quality of chia seeds as a function of coat color and fungicide treatment. The experiment followed a completely randomized design with a 2 × 2 factorial arrangement and six replications. For this, seeds were divided into two groups according to coat color (black and white) and subjected or not to treatment with carboxin + thiram. Germination speed index, germination rate, and shoot length were evaluated in plants sown at 0, 90, and 180 days after seed treatment. Germination rate and speed index differed significantly between coat colors, with white seeds having higher vigor than black seeds. Shoot length, however, differed only for seeds sown on the day of treatment, indicating that treated seeds were more vigorous. Salvia L.

ABSTRACT: Acute abdomen cases are among the most prevalent and challenging illnesses in equine medicine. The diagnosis includes anamnesis and detailed clinical evaluation of the patient, allowing the gathering of several important information and, additionally, the use of complementary exams helps to define the diagnosis and prognosis of each case. This research applied the multiple correspondence analysis (MCA) in data referring to clinical examination information and outcome of horses with colic referred to a hospital in Rio Grande do Sul, Brazil. Fifty eight horses were included in the analysis and, it was possible to identify significant differences between the groups, survivors and non-survivors. Related to clinical signs, non-survivor cases are distinguished by severe pain, lack of motility, mucosal alteration, capillary refill time greater than 2sec, heart rate more than 48bpm and presence of nasogastric reflux. As complementary exams, hematocrits and blood lactate demonstrate significative difference among the groups. The cardiovascular parameters, including heart rate, mucosal color and capillary refill time, were the variables with the greatest contribution to discriminate animals that non-survive from those that were discharged. Thus, clinical evaluation should not be underestimated and complementary exams should be used in conjunction to seek a better prognosis. The MCA allowed to visualize the data and predict the outcome of the patients.

Groundwater is considered an important source of water aid for human consumption. However, this water can be contaminated by impurities, such contamination spots that might reach the water tables. The aim of this study was to investigate the quality of shallow groundwater in Flores neighborhood, located in the municipality of Benevides, within Belém metropolitan region, State of Pará, Brazil. Recommendations described in Standard Methods for Examination of Water and Wastewater were followed at the time to determine physical-chemical parameters such as potential hydrogen (pH), electrical conductivity (EC), total dissolved solids (TDS), apparent color, turbidity, total hardness (TH), ions and trace elements. Multivariate statistical analysis has shown that most predictive water-quality parameters set for human consumption are associated with natural events involving weathering and leaching processes. Nevertheless, parameters of nitrate, phosphate, EC, TDS and pH are also influenced by anthropic conditions in the surroundings, mainly phosphate and nitrate ions. Therefore, it can be concluded that shallow groundwaters in Flores neighborhood are unsuitable for human consumption, making it necessary for municipal public authorities to take action to solve the problem of water shortage in the borough, thus preventing the population from use those shallow groundwaters, as their consumption can bring health problems.

RESUMO: O melão de polpa alaranjada honeydew apresenta elevado potencial nutricional e econômico, sendo amplamente apreciado como fruta doce e refrescante. Portanto, avaliar amostras comerciais de produtos tão relevantes para o mercado de frutas frescas é de grande importância. O objetivo deste estudo foi investigar a capacidade antioxidante, os parâmetros de qualidade e a composição química de melões do mercado brasileiro. Os valores de pH e ºBrix determinados para as amostras de melão foram 6,5 ± 0,30 e 9,2 ± 0,80 g/100 g (peso fresco), respectivamente, o que está de acordo com os resultados esperados para melões de alta qualidade. A análise cromatográfica revelou a sacarose (49% do açúcar total) como principal açúcar, seguida pela frutose (30%) e glicose (21%). Os carotenóides, que estão diretamente ligados à cor laranja característica, apresentaram teor total de 270,59 µg/g (peso seco). Além disso, o maior valor de b* comparado ao valor de a* indica a maior contribuição da cor amarela. Quanto ao potencial antioxidante, além de apresentar capacidade antioxidante para ambos os métodos aplicados, DPPH e FRAP, níveis variando de 16,40 ± 0,21 µmol equivalente de ácido ascórbico/g a 56,98 ± 0,80 µmol equivalente de Trolox/g (peso seco) foram encontrados nos extratos de melão. Ademais, os resultados foram maiores em termos de FRAP do que em DPPH. Desta forma, os resultados destacam os melões avaliados como fontes valiosas de compostos bioativos, como carotenóides e fenólicos, que contribuem para suas propriedades antioxidantes. Além disso, análises de cor, pH e teor de sólidos solúveis totais também refletem os atributos de qualidade.

ABSTRACT: Orange-fleshed non-netted honeydew melon has high nutritional and economic potential, being widely appreciated as a refreshing sweet fruit. Therefore, evaluating commercial samples of such relevant products for the fresh fruit market is of great importance. This study investigated the antioxidant capacity, quality parameters, and chemical composition of honeydew melons from the Brazilian market. The values of pH and °Brix determined for melon samples were 6.5 ± 0.30 and 9.2 ± 0.80 g/100 g (fresh weight), respectively, which agree with the results expected for high-quality melons. The chromatography analysis revealed sucrose (49% of total sugar) as the main sugar, followed by fructose (30%) and glucose (21%). Carotenoids, which are directly linked to the characteristic orange color, showed a total level of 270.59 µg/g (dry weight). Additionally, the higher b* value compared to a* value indicates the highest yellow contribution. Regarding the antioxidant assays, in addition to presenting antioxidant capacity for both methods applied, DPPH and FRAP, levels ranging from 16.40 ± 0.21 µmol ascorbic acid equivalent/g to 56.98 ± 0.80 µmol Trolox equivalent/g (dry weight) were reported in melon extracts. Moreover, the results were higher in terms of FRAP than DPPH. Therefore, the results underscore the evaluated honeydew melons as valuable sources of bioactive compounds, such as carotenoids and phenolics, which contribute to their antioxidant properties. Besides, analyses of color, pH, and total soluble solids content also reflect the quality attributes.

ABSTRACT: The tomato (Solanum lycopersicum L.) plays a vital role in global agriculture and is a model organism in genetic studies. Visual classification of tomatoes for genetic improvement programs faces challenges due to variety diversity, uneven ripening, external damages, and evaluator subjectivity. Recent advances in the field of computational resources, such as image phenotyping have enabled pre- and post-harvest assessments that are both fast and precise. This study aimed to classify tomato fruits based on shape, group, color, and defects using Convolutional Neural Networks (CNNs). The performance of five architectures - VGG16, InceptionV3, ResNet50, EfficientNetB3, and InceptionResNetV2 was evaluated to identify and determine the most efficient one for this classification. The research considered ten hybrids and their five parental lines. The experiment was conducted in the field, and images of ripe fruits were acquired using a portable mini studio. The ExpImage package in R software was used for fruit individualization by image and to aid in creating a synthetic database for network training. Images were grouped according to their classifications in terms of shape, color, groups, and defects. The InceptionResNetV2 architecture was the most efficient, achieving metrics such as precision and recall exceeding 93 % for most analyzed variables, and shorter classification times. This study advances the understanding of CNN applications in agriculture and research and provides valuable guidelines for optimizing classification tasks in distinct types of fruits.

ABSTRACT: To improve the nutritional and functional quality of agro-industrial waste, his study established a ternary mixture of flours made from pineapple, acerola, and passion fruit waste using the simplex-centroid design, as well as to evaluate their effects on the physicochemical and sensory characteristics of edible ice cream. Using mixture planning, nine ternary flour components were applied to edible ice cream formulations to evaluate acceptance scores for taste, texture, and overall impression attributes, as well as physicochemical parameters (pH, acidity, soluble solids, and color parameters) and microbiological parameters (thermotolerant coliforms at 45 ºC, Enterobacteriaceae and Salmonella). The simplex-centroid design demonstrated that the cubic model best predicts the results for the analyzed sensory attributes. The response surface graphs indicated the area of greatest acceptance in the formulations with the maximum percentage established for the flour with acerola waste. The highest level of acceptability was given to the ternary mixture of 60%, 30%, and 10% pineapple, passion fruit, and acerola flours, respectively. The results indicated that sorbet enriched with flour composed of the ternary mixture is a product with the potential for exploitation, as well as contributing to the reduction of environmental impacts generated by the large and improper disposal of agro-industrial fruit processing residues in the ecosystem.

Brazil is home to a rich biodiversity of native edible fruits renowned for their health-promoting compounds and flavors. Among these, Eugenia uniflora L. (Brazilian pitanga) is particularly notable. The fruit varies in color from yellow to purple and is prized for its intense aroma and versatile taste profile. However, information about the compounds responsible for their nutritional and sensory potential is still limited. This study analyzed volatile compounds and metabolites in yellow, red and purple pitanga fruits (Eugenia uniflora) at various ripening stages, exploiting a metabolomics approach. Yellow pitanga had 30 volatile compounds, with esters (40%), terpenes (26.67%) and aldehydes (16.67%) constituting 83.34% of identified volatile compounds. Red pitanga featured 26 volatile compounds, primarily terpenes and esters (each 30.77%) and aldehydes (15.38%), making up 76.92%. Purple pitanga contained 39 volatile compounds, with terpenes and esters (each 35.90%) and aldehydes (17.95%), totaling 89.75% of identified volatile compounds. Across all pitanga types, 124 metabolites were identified, including saturated fatty acids (17.74%), terpenes (17.74%) and sugars (16.93%), constituting 52.41% of identified metabolites. Future studies should provide nutritional information, consumption methods and industrial applications for pitanga fruits, focusing on sensory analysis, health benefits, preservation and breeding to enhance bioactive compounds and flavor. healthpromoting promoting flavors these L Brazilian notable profile However limited stages approach 3 40%, 40 40% , (40%) 26.67% 2667 67 (26.67% 16.67% 1667 16 (16.67% 8334 83 34 83.34 2 each 30.77% 3077 77 15.38%, 1538 15.38% 15 38 (15.38%) 7692 76 92 76.92% 35.90% 3590 35 90 17.95%, 1795 17.95% 17 95 (17.95%) 8975 89 75 89.75 types 12 17.74%, 1774 17.74% 74 (17.74% 16.93%, 1693 16.93% 93 (16.93%) 5241 52 41 52.41 analysis benefits flavor 4 (40% 26.67 266 6 (26.67 16.67 166 1 (16.67 833 8 83.3 30.77 307 7 153 15.38 (15.38% 769 9 76.92 35.90 359 179 17.95 (17.95% 897 89.7 177 17.74 (17.74 169 16.93 (16.93% 524 5 52.4 (40 26.6 (26.6 16.6 (16.6 83. 30.7 15.3 (15.38 76.9 35.9 17.9 (17.95 89. 17.7 (17.7 16.9 (16.93 52.

ABSTRACT Capsicum annuum is a domesticated pepper species that exhibits a wide range of fruit size, color, and shape, as well as plant characteristics important for ornamental pepper cultivars, including plant architecture and leaf size and color. This variability can be found in Capsicum accessions from germplasm banks and used in breeding programs to develop new ornamental pepper cultivars. The objective of this study was to develop the ornamental characterization and pre-breeding of a segregating Capsicum annuum accession from the Active Germplasm Bank of Capsicum of the Brazilian Agricultural Research Corporation (Embrapa Temperate Climate). Sixty-seven F1-generation and sixty-two F2-generation plants were characterized based on 16 morphological descriptors: stem color, nodal anthocyanin, plant growth habit, branching density, leaf density, leaf color, number of leaves per axil, flower position, corolla color, calix pigment, immature fruit color, fruit position, mature fruit color, fruit shape, fruit apex shape, and fruit brightness. The relative contribution of each trait to the genetic divergence was determined using the method proposed by Singh (1981). A principal component analysis was carried out. Almost all evaluated variables showed segregation, except for flower position and immature fruit color. Genetic variability was found in both F1 and F2 generations, indicating their potential for developing ornamental Capsicum annuum varieties. color shape cultivars prebreeding pre Embrapa Climate.

Abstract: Color and glossiness are two important aesthetic properties of wood flooring and wood furniture that significantly affect consumers choice. With time the coating deteriorates altering the surface properties. Understanding these changes is important for furniture industry, impacting design choices, material selection, and long-term maintenance. The effects of thermal aging (30 °C for 30 days, 60 °C for 60 days, and 90 °C for 90 days) on color parameters (C*, L*, b*. a*, h o) and glossiness on both perpendicular (⊥) and parallel (║) directions at 20°, 60°, and 85° angles in UV-cured coatings applied on sessile oak were studied. Results show that statistically significant differences were observed in the glossiness values, as well as in C*, b*, a*, L* and h o. As the temperature and duration of the thermal aging process increased, there was a noticeable increase in the values of color parameters b*, a*, and C*, while the values of h o and L* decreased. The characteristics of the surfaces exposed to thermal aging have undergone a complete transformation.

ABSTRACT: The objective of this study is to analyze the female stereotypes represented in the Harry Potter saga. The research is qualitative, using content analysis as a method and observation as a research technique. The results of the re-search showed that the women in the study, although they have a variety of eye and hair colors, are all white-skinned, and the majority only use natural makeup for different occasions. On the other hand, the strength in the female characters is almost non-existent. Finally, the research concludes that the characteristics help encourage the viewer to continue having an ideal woman in mind, and the physical descriptions do not help the identification of different girls in the world with their favorite female characters.

RESUMEN: El presente estudio tiene como objetivo el analizar los estereotipos femeninos representados en la saga Harry Potter. La investigación es cualitativa. Se usa, como método, el análisis de contenido; y como técnica de investigación, la observación. Los resultados de la investigación indicaron que, las mujeres de estudio, aunque tienen variedad de color de ojos y cabello, todas son de piel blanca; incluso la mayoría solo usa el maquillaje natural para diferentes ocasiones. Por otro lado, la fuerza en los personajes femeninos es casi inexistente. Finalmente, la investigación concluye que las características ayudan a incentivar a que el espectador siga teniendo una mujer ideal en mente, y las descripciones físicas no ayudan a la identificación de las diferentes niñas del mundo con sus personajes femeninos favoritos.

Abstract This research analyzes how individual characteristics (area of origin, skin color, economic status of origin and education) and structural factors (economic growth and trade openness) influence in Mexico the opportunities to obtain a high level of economic well-being. Using a IV-probit model estimated in two stages with instrumental variables in a context of complex samples, it is identified that people born in homes with low economic status, originating from rural localities and with brown skin have lower probabilities of economic success compared to people of non-low economic status, from urban areas and light skin. The findings also reveal that economic growth and educational achievement increase the probabilities of obtaining a high economic status, but the increase in probabilities is bigger for people of non-low economic origin, coming from urban areas and light skin. Finally, through the different rates of growth and school achievement, the differences in economic well-being widen, which indicates an increase in inequality between privileged and non-privileged groups. This research is innovative since it not only analyzes the effect of economic growth and academic achievement on social mobility, but also provides an empirical method that investigates the effect of growth and academic achievement on inequality of opportunities for socioeconomic advancement. The results indicate the existence of irrational mobility barriers based on criteria over which the individual has no control.

Resumen La presente investigación analiza cómo influyen en México las características del individuo (ámbito de origen, color de piel, estatus económico de origen y educación) y los factores estructurales (crecimiento económico y apertura comercial) en las oportunidades de obtener un nivel de bienestar económico alto. Por medio de un modelo probit, estimado en dos etapas con variables instrumentales en un contexto de muestras complejas, se identifica que las personas nacidas en hogares con estatus económico bajo, originarias de localidades rurales y de piel morena, tienen menores probabilidades de éxito económico con respecto a las personas de estatus de origen económico no-bajo, provenientes del ámbito urbano y piel clara. Los hallazgos también revelan que el crecimiento económico y el logro escolar aumentan las probabilidades de obtener un estatus económico alto, pero el incremento de probabilidades no es homogéneo, sino que favorece en mayor medida a personas de origen económico no-bajo, provenientes del ámbito urbano y piel clara. Finalmente, se identifica que, a través de las distintas tasas de crecimiento y logro escolar, las diferencias en el bienestar económico se amplían, lo que indica aumento de la desigualdad entre grupos privilegiados y no-privilegiados. La ruta de investigación es innovadora ya que no solo analiza el efecto del crecimiento económico y el logro académico en la movilidad social, sino que también aporta un método empírico que indaga el efecto del crecimiento y el logro académico en la desigualdad de oportunidades de ascenso socioeconómico. Los resultados indican la existencia de barreras de movilidad irracionales basadas en criterios sobre los que el individuo no tiene control.

Abstract One physical modification (autoclaving) and five chemical modifications (lintnerization, crosslinking, acetylation, hydroxypropylation, and oxidation) were performed on the native oat starch. The starches were mixed with chitosan (Ch) and plasticizer (glycerol) to make films. The film-forming solutions (FFS) were characterized rheologically and evaluated for physical properties (color, thickness, humidity and solubility), water vapor and oxygen permeability (10 and 25 °C), and mechanical properties. Antibacterial activity was evaluated against Escherichia coli, Staphylococcus aureus and Listeria monocytogenes by the agar diffusion. The functionality of the films as packaging in ground pork was evaluated by counting fecal coliforms and total aerobes for 21 days at 4°C. All the FFS presented a pseudoplastic-type behavior. The addition of Ch increased the stress at fracture (TF) and decreased the percentage elongation (% E) in all the films; being the Oxidized-Ch formulation the one that presented the greatest increase (≈ 200 %) in TF and the smallest decrease (38 %) in % E. All formulations with Ch presented antibacterial activity, which was higher in the Oxidized-Ch film and decreased with the evaluation time. The results generally indicated that the Oxidized-Ch film may represent a suitable formulation as antibacterial packaging with adequate physical, mechanical, and barrier properties.

Resumen Se realizó una modificación física (autoclaveado) y cinco modificaciones químicas (lintnerización, entrecruzamiento, acetilación, hidroxipropilación y oxidación) al almidón nativo de avena. Los almidones se mezclaron con quitosano (Q) y plastificante (glicerol) para elaborar películas. Las soluciones formadoras de película (SFP) se caracterizaron reológicamente. En las películas se evaluaron las propiedades físicas (color, grosor, humedad y solubilidad), la permeabilidad al vapor de agua y al oxígeno (10 y 25 °C) y las propiedades mecánicas. Se evaluó la actividad antibacteriana frente a Eschericia coli, Staphylococcus aureus y Listeria monocytogenes mediante el método de difusión en agar. La funcionalidad de las películas como envase de carne picada de cerdo se evaluó mediante el recuento de coliformes fecales y aerobios totales durante 21 días a 4°C. Todas las SFP presentaron comportamiento pseudoplástico. La adición de Q aumentó la tensión a la fractura (TF) y disminuyó el porcentaje de elongación (% E) en todas las películas; siendo la formulación Oxidado-Q la que presentó el mayor incremento (≈ 200 %) en TF y la menor disminución (38 %) en %E. Todas formulaciones con Q presentaron actividad antibacterial, la cual fue mayor en la película Oxidado-Q y disminuyó con el tiempo de evaluación. En general, los resultados indicaron que la película Oxidado-Q puede representar una formulación conveniente como envase antibacteriano con adecuadas propiedades físicas, mecánicas y de barrera.

Resumen Presentamos dos nuevos registros de leucismo en dos especies de aves de dos localidades de México. En primer lugar, reportamos un individuo de Golondrina Tijereta (Hirundo rustica); el individuo fue un polluelo observado entre el 15 de julio y el 6 de agosto del 2010 en un área suburbana del centro de Jalisco, el cual presentó coloración gris blanquizca y ojos oscuros. También reportamos un Zopilote Aura (Cathartes aura) con leucismo observado el 4 de noviembre del 2014 sobrevolando la ciudad de José Cardel, Veracruz mientras migraba; el individuo presentó plumas primarias blancas mezcladas con secundarias obscuras, coberteras primarias blancas, cuello y pecho blancos. Nuestros reportes representan el primer registro en México de leucismo de la Golondrina Tijereta, y el primer reporte publicado de un zopilote con leucismo migrando a través del centro de Veracruz, respectivamente. Nuestras observaciones también muestran que ambos individuos leucísticos realizaban actividades regulares de su ciclo de vida, enriqueciendo el conocimiento disponible sobre las anormalidades cromáticas en las aves mexicanas.

Abstract We present two new records of leucism in two bird species from two locations in Mexico. First, we report one leucistic Barn Swallow (Hirundo rustica); the individual was a nestling observed between 15 July and 6 August 2010, in a suburban area of central Jalisco, showing gray-whitish coloration and dark eyes. We also report of one leucistic Turkey Vulture (Cathartes aura) spotted during the afternoon of 4 November 2014, flying overhead while migrating in the city of José Cardel, Veracruz; the individual showed white primary feathers interspersed with dark secondaries, white primary coverts, white neck, and chest feathers. Our records represent the first Mexican report of leucism in the Barn Swallow, and the first published report of a leucistic vulture migrating across central Veracruz, respectively. Our observations also show that both leucistic individuals were accomplishing regular life-cycle activities, enriching the available knowledge of chromatic abnormalities in Mexican birds.
