ABSTRACT Desertification is the degradation process caused by climatic conditions and human activities that results in loss of soil productivity and decline in vegetation growth in the long term. Several indices related to vegetation, soil and climate are used to monitor desertification, but few studies explore qualitative and quantitative aspects of indices on desertification on spatial and hierarchical scale. This study aims to identify and measure indices related to increased risk of desertification on global, local and hierarchical scales using multinomial logistic regression models. Images from TM, ETM+ and OLI sensor from 1997 to 2018 in the end of dry and rainy seasons were used to quantify NDVI, TGSI, albedo, temperature, aridity index, evapotranspiration and precipitation on global spatial scale (Irauçuba Centro Norte) and local spatial scale (Miraíma, Canindé, Irauçuba and Santa Quitéria). GISD was calculated by geometric mean of weighted indices and segmented into 8 classes of susceptibility to desertification (hierarchical scale). The results showed that the best models were obtained on local scale and for the end of the rainy season. Temperature proved to be the most important variable for increased risk of desertification on global, local and hierarchical scales. Therefore, the increase in the risk of desertification in the studied areas is due to human activities of deforestation, overgrazing and fire. These factors contributed to reduction of vegetation cover and increase in temperature, changing the microclimatic, which led to decline in precipitation and worsening of desertification. term TM ETM 199 201 NDVI TGSI albedo temperature index Norte Miraíma, Miraíma (Miraíma Canindé Quitéria.

Abstract This study handles the possibility of formulating artisanal paints for wall paintings whose pigments come from plants, considering the need for additives and techniques capable of guaranteeing a good performance for internal walls of buildings. The lack of recipes and publications on the proportion of each component to obtain a paint with good performance motivated the preparation of the present research, in which formulations were developed through experimental design of mixtures to obtain homogeneous suspensions that comply with the limits stipulated by NBR 15079-1:2021. The performance of the mixtures in the Abrasion Resistance Test was evaluated according to the variations in the proportions of the components of the mixtures, and the pH and viscosity variable. The results indicate that the highest levels of abrasion resistance were achieved by raising the levels of pigment and bactericide, while high pH indices showed high viscosity and good performance against abrasion resistance, and vice versa. Through this study, it is concluded that it is possible to elaborate paints with Curcuma Longa L. pigments and natural inputs with satisfactory performance for the application and elaboration of mural paintings on internal walls of buildings. plants buildings research 1507912021. 1507912021 15079 1 2021. 2021 15079-1:2021 variable bactericide versa L 150791202 1507 202 15079-1:202 15079120 150 20 15079-1:20 1507912 15 2 15079-1:2 150791 15079-1: 15079-1 15079-

Resumo Opresente estudo buscou formular tintas artesanais para pinturas de murais cujos pigmentos sejam oriundos de plantas, considerando a necessidade de aditivos e técnicas capazes de garantir um bom desempenho para paredes internas de edificações. A falta de receitas e publicações sobre a proporção de cada componente para a obtenção de uma tinta com bom desempenho motivou a elaboração da presente pesquisa, em que foram desenvolvidas formulações através de delineamento experimental de misturas para obter suspensões homogêneas que estejam em conformidade com os limites de desempenho definidos pela NBR 15079-1:2021. O desempenho das misturas frente ao ensaio de resistência à abrasão (RAU) foi avaliado de acordo com as variações das proporções dos componentes das misturas e as variáveis de pH e viscosidade. Os resultados indicam que os índices mais elevados de RAU foram alcançados ao elevar os níveis de pigmento e bactericida, ao passo que altos índices de pH apresentaram viscosidade elevada e bom desempenho frente à RAU, e vice-versa.

Abstract Purpose: To adapt and validate in Sonora the scale to measure Attitudes towards Transgender People in University Students (EATU), which measures the inclusion of trans people in Higher Education Institutions (HEIS). Methodological design: Quantitative, cross-sectional and non-experimental study. 860 participants were selected among three HEIS, with non-probabilistic and intentional sampling. A 4-point Likert-type scale survey was applied that evaluates transinclusive attitudes. Reliability was obtained with Cronbach's alpha and McDonald's omega. For validity, the sample was randomly divided into two; In subsample 1, an Exploratory Factor Analysis (EFA) was carried out and in subsample 2, the model resulting from the EFA was tested using a Structural Equation Model (SEM). Results: The EFA yielded a final solution EATU of 32 items grouped into 3 dimensions called sensitivity, coexistence and cisexist stigma, with values that demonstrate validity and reliability. The SEM generated a model with indices of fitness in a final solution of 17 items and 3 correlated dimensions with acceptable coefficients. Research limitations: The measurement of transinclusion attitudes in a society where it has been documented that such construct is barely being developing, and the failure to collect demographic data on the sample about their religious beliefs. Findings: A measurement instrument on transinclusive attitudes for key social actors interested in promoting the inclusion of trans people, their human rights and substantive equality.

Resumen Introducción. Estudios de defoliación en caña de azúcar en México son escasos, se desconoce a qué edad de la planta y en qué época del año se deben realizar. Objetivo. Evaluar el efecto de la defoliación artificial en caña de azúcar en diferentes etapas de cultivo y su respuesta sobre parámetros de calidad y rendimiento. Materiales y métodos. El experimento se llevó a cabo en la zafra 2020-2021 entre los meses de abril y mayo, en una parcela ubicada en una soca del cultivar COLPOSCTMEX 06-039, dentro de la zona de abastecimiento del Ingenio Presidente Benito Juárez de la Chontalpa, Tabasco. Se utilizó un diseño experimental de bloques completamente al azar, donde los tratamientos de defoliación consistieron en eliminar las hojas completas del tallo hasta dejar la hoja +5 (H5). Los tratamientos de defoliación se aplicaron a los 8, 9 y 10 meses de edad del cultivo, más un testigo sin defoliación, con cinco repeticiones por tratamiento. Los parámetros de crecimiento evaluados fueron altura y diámetro de planta, número de tallos e índices de área foliar (IAF) y de vegetación de las diferencias normalizada (NDVI). Al momento de la cosecha se midieron los °Brix y los rendimientos agrícolas de la caña de azúcar. Resultados. Se encontró que los parámetros de crecimiento y calidad fueron disminuidos por los tratamientos de defoliación total. El tratamiento 2 mostró los mayores valores de altura y diámetro de planta, menor NDVI y rendimiento de tallos al momento de la cosecha y la defoliación afectó el IAF. Los °Brix no se vieron afectados por los diferentes tratamientos de defoliación. Conclusión. La defoliación a los nueve meses de edad aumentó el rendimiento agrícola y no afectó la calidad de los jugos.

Abstract Introduction. Defoliation studies on sugarcane in Mexico are scarce, and it is unknown at what age of the plant and in which season of the year it should be carried out. Objective. To evaluate the effect of artificial defoliation in sugarcane at different stages of growth and its response on quality and yield parameters. Materials and methods. The experiment was conducted during the 2020-2021 harvest between the months of April and May, in a plot located in a ratoon of the cultivar COLPOSCTMEX 06-039, within the supply area of the Ingenio Presidente Benito Juárez in the Chontalpa region, Tabasco. A completely randomized block design was used, where the defoliation treatments consisted of removing the entire leaves of the stem until leaving the +5 leaf (H5). Defoliation treatments were applied at 8, 9, and 10 months of crop age, plus a control without defoliation, with five replicates per treatment. Growth parameters evaluated were plant height and diameter, number of stalks, and leaf area index (IAF) and normalized difference vegetation index (NDVI). At harvest, °Brix and sugarcane yields of sugarcane were measured. Results. It was found that growth and quality parameters were reduced by total defoliation treatments. Treatment 2 showed the highest values of plant height and diameter, lower NDVI, and stalk yield at harvest, and defoliation affected the IAF. °Brix were not affected by different defoliation treatments. Conclusion. Defoliation at nine months of age increased agricultural yield and did not affect juice quality.

Summary: The fraction of vegetation cover (FVC) and the Leaf Area Index (LAI) are biophysical variables closely related to the evapotranspiration rate of crops and their biomass production. Despite their importance, they are usually not measured directly due to their time-consuming and costly nature; however, they can be estimated on a large scale and near-real-time using spectral information captured in satellite images, although this requires prior validation at the field level. Simple linear regression models were developed and validated using 13 vegetation indices (VI) related to LAI and FCV in alfalfa (Medicago sativa). Three spectral information sources were used: (i) reflectance to derive the VI; (ii) digital photographs processed with the Canopeo application to estimate FVC; and (iii) direct LAI measurements using a ceptometer. Six field samples were taken between March and June, 2020 in four alfalfa plots located in Palmar de Bravo, Puebla, Mexico. To evaluate each VI, the determination coefficient (R2) and the root mean square error (RMSE) were used. We found that the most suitable VI for estimating FVC was the VIgreen (Green Vegetation Index, R2 =0.987 and RMSE = 0.093). For the LAI, the VI that performed best was the NDVI (Normalized Difference Vegetation Index, R2 = 0.935 and RMSE = 0.746). The results showed the suitability and practical utility of spectral information for estimating biophysical variables in alfalfa cultivation and their monitoring.

Resumen: La fracción de cobertura vegetal (FCV) y el índice de área foliar (IAF) son variables biofísicas relacionadas estrechamente con la tasa de evapotranspiración de los cultivos y su producción de biomasa. A pesar de su importancia, usualmente no se miden de manera directa debido al tiempo invertido y costo; sin embargo, se pueden estimar a gran escala y en tiempo casi real mediante información espectral captada en imágenes de satélite, pero esto requiere de su validación a nivel de campo. Se desarrollaron y validaron modelos de regresión lineal simple utilizando 13 índices de vegetación (IV) relacionados con el IAF y la FCV en alfalfa (Medicago sativa). Se usaron tres fuentes de información espectral: (i) La reflectancia para derivar los IV; (ii) fotografías digitales procesadas con Canopeo para estimar la FCV; y (iii) mediciones del IAF utilizando un ceptómetro. Se realizaron seis muestreos de campo entre marzo y junio de 2020, en cuatro parcelas de alfalfa situadas en Palmar de Bravo, Puebla, México. Para evaluar cada IV, se utilizó el coeficiente de determinación (R2) y la raíz del cuadrado medio del error (RCME). Se encontró que el IV más apropiado para estimar la FCV fue el VIgreen (Green Vegetation Index, R2 = 0.987 y RCME = 0.093). En el caso del IAF, el IV que presentó el mejor desempeño fue el Normalized Difference Vegetation Index (NDVI), R2 = 0.935 y RCME = 0.746). Los resultados mostraron la aptitud y utilidad práctica de la información espectral para estimar las variables biofísicas en el cultivo de alfalfa y su monitoreo.

Abstract The objective of the study was to analyze the relationship between academic stress and self-concept, to compare both variables according to gender, and to identify the predictive capacity of self-concept factors in the levels of academic stress in university students. The results confirmed a negative association between academic stress and self-concept and significant differences between men and women. Additionally, a multiple linear regression analysis differentiated by sex was performed. In the case of women, the model was constituted by the emotional, academic-work, social, family and physical factors of self-concept; in the case of men, only the emotional and academic-work dimensions were integrated. It is concluded that the self-concept contributes to the prediction of the behavior of academic stress in higher education students. For these reasons, it is convenient to promote activities for students in university institutions that improve their perception of themselves.

Resumen Los objetivos centrales de la indagatoria fueron analizar la asociación entre el estrés académico y el autoconcepto, comparar dichos fenómenos psicológicos entre géneros e identificar el poder predictivo de los factores del autoconcepto en los índices de estrés académico en estudiantes universitarios. Los resultados confirmaron una asociación negativa entre las variables abordadas y diferencias hombres y mujeres. Adicionalmente, se realizaron dos análisis de regresión lineal múltiple para cado uno de los géneros. En mujeres, los factores emocional, académico-laboral, social, familiar y físico del autoconcepto aportaron a la explicación del estrés académico; en el de los hombres, solo se integraron las dimensiones emocional y académico-laboral. Se concluye que el autoconcepto aporta a la predicción del comportamiento del estrés académico en estudiantes de educación superior. Por tales razones, resulta conveniente suscitar en las instituciones universitarias, actividades tendientes a la mejora de la percepción de sí mismos por parte de los jóvenes.

Abstract: Given the prevalence of mental disorders and elevated psychological symptoms, there has been a call for action to scale up health services. To provide optimal care, detecting symptoms early and evaluating the psychological state is essential. Self-report measures are useful to evaluate specific diagnoses and explore psychological symptoms. The present study aimed to provide new psychometric evidence of the Argentine version of the Brief Symptoms Checklist. Through non-probabilistic and intentional sampling, 760 individuals aged 18 to 63 (M = 28.1; SD = 8.61) were selected. Confirmatory factor analysis showed that the nine correlated factors model exhibited the best-fit indices and yielded full configural, metric and scalar invariance across gender and region. The factors mainly showed adequate reliability values similar to previous research. T values are provided as population-based norms. The results showed that the instrument is valid and reliable, and could be a valuable tool in various contexts, particularly in primary care, where the evaluation requires a very short time and useful information.

ABSTRACT The global COVID-19 pandemic caused significant economic and financial losses in the Ecuadorian banking sector. This study aims to determine the extent to which credit risk and liquidity affect the profitability of mutual savings banks in Ecuador between 2018 and 2021. To this end, the population consisted of the four existing mutual savings banks, and data from a panel of 192 observations were used, applying a PLS-SEM model to demonstrate the relationships. The results showed that credit risk has a negative impact on the liquidity and profitability of these financial institutions; in the case of liquidity, it was found that it does not affect profitability. Consequently, it is essential to control credit risk through delinquency indices, which makes it necessary to consider the structure of the loan portfolio.

RESUMEN La pandemia mundial producto del COVID-19 ocasionó importantes pérdidas económicas y financieras en el sector bancario ecuatoriano. El objetivo del presente estudio es determinar en qué medida el riesgo crediticio y la liquidez afectan la rentabilidad de las mutualistas en Ecuador, entre el 2018 y 2021. Para tal efecto, la población estuvo constituida por las cuatro mutualistas existentes, con cuyos datos se trabajó con datos de panel de 192 observaciones, aplicando un modelo PLS-SEM para evidenciar las relaciones. De esta manera, los resultados mostraron que el riesgo crediticio incide negativamente sobre la liquidez y la rentabilidad de estas instituciones financieras; en el caso de la liquidez, se ha podido percibir que esta no afecta a la rentabilidad. En consecuencia, es sumamente importante controlar el riesgo crediticio, a través de los índices de morosidad, por lo que es necesario considerar la estructura de cartera.

RESUMO A região Nordeste do Brasil é caracterizada por clima tropical e altas temperaturas do ar em curto ou longo prazo, o que pode afetar negativamente o crescimento e os processos fisiológicos do morangueiro (Fragaria x ananassa Duch). Nesse contexto, para mitigar os impactos do estresse térmico, destaca-se a necessidade de empregar variedades adaptadas e tecnologias, como uso de condicionadores de solo. Assim, o objetivo deste estudo foi avaliar as respostas fisiológicas e o índice térmico de cultivares de morango cultivadas sob doses de hidrogel no substrato. O estudo foi conduzido em ambiente protegido em Guaraciaba do Norte, Ceará, Brasil, utilizando delineamento experimental em blocos casualizados com quatro repetições, em arranjo fatorial 5 × 2 composto por cinco doses de hidrogel no substrato (0, 1, 2, 3, e 4 g L-1) e duas cultivares de morango (‘Albion’ e ‘San Andreas’). As variáveis de crescimento (número de folhas, diâmetro da coroa e altura das plantas) foram avaliadas aos 15 e 45 dias após o transplantio (DAT). As trocas gasosas (condutância estomática, taxa de transpiração, taxa de assimilação de CO2 e concentração intercelular de CO2), índices fisiológicos (eficiência intrínseca do uso da água, eficiência instantânea de carboxilação e eficiência instantânea do uso da água) e índice térmico foram avaliados aos 90 DAT. prazo Fragaria Duch.

ABSTRACT The Northeast region of Brazil is characterized by a tropical climate and high air temperatures, which can negatively affect the growth and physiological processes of strawberry plants (Fragaria x ananassa Duch) in the short- or long-term. In this context, the use of adapted varieties and technologies such as soil conditioners is necessary. Thus, the objective of this study was to assess the physiological responses and the thermal index of strawberry cultivars grown under hydrogel doses in the substrate. The study was conducted in a protected environment in Guaraciaba do Norte, Ceará state, Brazil, using a randomized block experimental design with four replicates, in a 5 × 2 factorial arrangement consisting of five hydrogel doses in the substrate (0, 1, 2, 3, and 4 g L-1) and two strawberry cultivars (‘Albion’ and ‘San Andreas’). Growth variables (number of leaves, crown diameter, and plant height) were evaluated at 15 and 45 days after transplanting (DAT). Gas exchanges (stomatal conductance, transpiration rate, CO2 assimilation rate, and intercellular CO2 concentration), physiological indices (intrinsic water use efficiency, instantaneous carboxylation efficiency, and instantaneous water use efficiency), and thermal index were evaluated at 90 DAT. Strawberry plant growth increased significantly as the hydrogel dose in the substrate was increased. The hydrogel dose of 4 g L-1 reduced gas exchanges at 90 DAT, regardless of the cultivar. Plants of the cultivar San Andreas showed higher intrinsic water use efficiency and lower thermal index when grown under the hydrogel dose of 4 g L-1. temperatures Fragaria Duch short longterm. longterm long term. term long-term context necessary Thus Norte state replicates 0, 0 (0 1 3 L1 L ‘Albion Albion (‘Albion Andreas. .

O meio rural brasileiro apresenta uma grande heterogeneidade, e parte de seus moradores convivem com altos índices de insegurança alimentar, especialmente entre os assalariados sem registro formal e famílias não ocupadas. No total, 1,4 milhão de famílias enfrentam insegurança alimentar moderada ou grave. Entre os desempregados no campo, 29% vivem nessa condição, enquanto 19% os assalariados agrícolas sem formalização nas relações de também sofrem com essa vulnerabilidade. Na agricultura familiar, 11% sofrem com privações alimentares. A precariedade do trabalho informal, a subocupação e o desemprego são fatores-chave que agravam a insegurança alimentar no campo. O desafio é criar políticas públicas direcionadas que atendam às necessidades específicas desses grupos vulneráveis.

The Brazilian rural environment exhibits significant heterogeneity, with many residents experiencing high levels of food insecurity, particularly among informal wage laborers and non-occupied families. In total, 1.4 million families face moderate to severe food insecurity. Among rural unemployed individuals, 29% live in such conditions, while 19% of informal agricultural wage laborers also suffer from this vulnerability. In family farming, 11% face food deprivation. The precariousness of informal work, underemployment, and unemployment are key factors exacerbating food insecurity in rural areas. Addressing these issues requires targeted public policies to meet the specific needs of these vulnerable groups.

Abstract Background: Canopy phenology, foliar biochemistry, and leaf lifespan vary according to season within and across species. Intrinsically, this variation should also determine changes in the spectral properties of foliar tissue. However, whether canopy phenology and leaf spectroscopy co-vary across species has seldom been tested in seasonal drylands. Questions and / or Hypotheses: We tested the covariation between growth rate, foliage phenology, and leaf spectral indices, expecting that species with high growth rates should have large variability in relative leaf number and foliar spectroscopy. Studied species / data description / Mathematical model: We partition the intra and interspecific variation in relative leaf number and spectroscopy within nine perennial chaparral shrub species. Study site and dates: Rancho El Mogor, Valle de Guadalupe, Baja California, during 2017 and 2018. Methods: Foliage phenology was quantified with an index of relative leaf number, foliar spectroscopy with three standard vegetation indices, and resource-use with stem growth and leaf functional traits. Results: Species with higher variability in foliage phenology (more deciduous species) had higher stem growth rates. The three vegetation indices varied significantly across species (ca. 20 % of explained variance), and across seasons within species (ca. 55 % of explained variance). The values of the three vegetation indices were correlated, and only NDVI was correlated with foliage phenology and stem growth. Conclusions: Our results show that variations in relative leaf number and spectroscopy in chaparral species are coupled with functional traits of species involved in resource exploitation strategies in a seasonally arid environment.

Resumen: Antecedentes: La fenología del follaje, bioquímica, longevidad foliar y propiedades espectrales del tejido foliar deben variar dentro y entre especies. Sin embargo, la covariación interespecífica entre fenología del follaje y espectroscopía foliar rara vez se ha demostrado en ambientes áridos estacionales. Preguntas y / o Hipótesis: Probamos la hipótesis de covariación intra e interespecífica entre tasas de crecimiento y variabilidad en fenología del follaje e índices espectroscópicos. Especies de estudio / Descripción de datos / Modelo matemático: La variación intra e interespecífica en número relativo de hojas, características funcionales y espectroscopía foliar se cuantificó en nueve especies de arbustos perennes de chaparrales. Sitio y años de estudio: Rancho El Mogor, Valle de Guadalupe, Baja California, de 2017 a 2018. Métodos: La fenología del follaje se cuantificó con índices del número relativo de hojas, junto con el crecimiento de tallo y variables funcionales de hojas y la espectroscopía con tres índices de vegetación. Resultados: Las especies deciduas presentaron mayores tasas de crecimiento en tallo. Los tres índices de vegetación variaron interespecíficamente (ca. 20 % varianza explicada), e intraespecíficamente entre estaciones (ca. 55 % varianza explicada). Los tres índices de vegetación estuvieron correlacionados y solamente NDVI se asoció con la variabilidad del follaje y el crecimiento de tallo. Conclusiones: El número relativo de hojas y la espectroscopía foliar de especies de chaparral están asociados con características funcionales en un ambiente árido estacional.

Abstract This paper involves the analysis of the quality of anthropometric data on children under five years of age in two information systems in the State of São Paulo. The sample included 2,117,108 children from the Food and Nutrition Surveillance System (SISVAN), and 748,551 from the State Milk Project (VIVALEITE). Initially, we evaluated the frequency of missing values and others outside the equipment spectrum and calculated the digit-to-weight preference index. After calculating height-for-age (HAZ), weight-for-age (WAZ), and body mass index-for-age (BAZ), we flagged the biologically implausible values (BIV) and calculated the standard deviation (SD). For each municipality, we calculated the mean and the SD of HAZ, WAZ, and BAZ; and plotted the SD values as a function of the mean. The digit-to-weight preference index was greater among children aged between 24 and 59 months in SISVAN. The frequency of BIV for HAZ (SISVAN 2.56%; VIVALEITE 0.98%) was higher than for WAZ (SISVAN 2.10%; VIVALEITE 0.18%). For HAZ, variations among municipalities were more pronounced in VIVALEITE than in SISVAN. The height variable presents low reliability in both systems. The weight variable reveals satisfactory quality in VIVALEITE and unsatisfactory quality in SISVAN. Paulo 2117108 2 117 108 2,117,10 SISVAN, SISVAN , (SISVAN) 748551 748 551 748,55 VIVALEITE. .

Resumo O objetivo foi analisar a qualidade dos dados antropométricos de crianças menores de cinco anos em dois sistemas de informação no estado de São Paulo. A amostra compreendeu 2.117.108 crianças do Sistema de Vigilância Alimentar e Nutricional (Sisvan) e 748.551 do Projeto Estadual do Leite (Vivaleite). Inicialmente, avaliamos a frequência de valores faltantes e fora do espectro do equipamento, e calculamos o índice de preferência de dígito para peso. Após calcular os índices de altura para idade (A-I), peso para idade (P-I) e índice de massa corporal para idade (IMC-I), identificamos os valores biologicamente implausíveis (VBI) e calculamos o desvio-padrão (DP). Para cada município, calculamos a média e o DP de A-I, P-I e IMC-I; e plotamos os valores de DP em função da média. A preferência de dígito no peso foi maior em crianças de 24 a 59 meses no Sisvan. A frequência de VBI para A-I (SISVAN 2,56%; Vivaleite 0,98%) foi maior do que para P-I (Sisvan 2,10%; Vivaleite 0,18%). Para o índice A-I as variações entre os municípios foram mais acentuadas no Vivaleite do que no Sisvan. A variável altura apresentou baixa confiabilidade nos dois sistemas. A variável peso apresentou qualidade satisfatória no Vivaleite e insatisfatória no Sisvan. Paulo 2117108 2 117 108 2.117.10 Sisvan 748551 748 551 748.55 Vivaleite. .

ABSTRACT Among weed control methods, chemical control using herbicides is one of the most widely employed due to its practicality and efficiency. However, there is still a lack of reliable information regarding the effectiveness of low-volume spraying and the droplet spectrum for contact herbicides, such as fomesafen. The objective was to determine the spray volume and droplet spectrum for applying the fomesafen herbicide and its efficacy in controlling hairy beggarticks (Bidens pilosa) and littlebell (Ipomoea triloba). The herbicide was applied using a CO2-pressurized knapsack sprayer with TT11002 spray tip spaced at 0.50 m, operating at pressures of 100 kPa (very coarse droplets) and 400 kPa (medium-sized droplets) with spray volumes of 35, 70, 140, and 280 L ha-1, obtained by varying the application speed. At the time of application, the percentage of covered area and droplet density (droplets cm-²) were evaluated on water-sensitive paper labels using the DropScope® program. The best control results for hairy beggarticks were achieved when the application was performed with very coarse droplets at a pressure of 100 kPa, with a spray volume between 65 and 280 L ha-1, droplet density exceeding 60 droplets cm-2, and coverage greater than 10%. Fomesafen does not provide effective control of littlebell. methods efficiency However lowvolume low Bidens pilosa Ipomoea triloba. triloba . triloba) CO2pressurized COpressurized CO2 pressurized CO TT TT1100 050 0 50 0.5 m 10 40 mediumsized medium sized 35 70 140 28 ha1, ha1 ha 1, 1 ha-1 speed cm² cm ² cm-² watersensitive water sensitive DropScope program 6 cm2, cm2 2, 2 cm-2 10% TT110 05 5 0. 4 3 7 14 ha- cm- TT11 TT1

RESUMO Dentre os métodos de controle de plantas daninhas, o químico, por meio de herbicidas, é um dos mais utilizados devido à sua praticidade e eficiência. No entanto, ainda faltam informações confiáveis sobre a eficácia de aplicações em baixo volume e o espectro de gotas a ser utilizado para herbicidas de contato, como o fomesafen. O objetivo deste trabalho foi determinar o volume de calda e espectro de gotas para aplicação do herbicida fomesafen, bem como a eficácia no controle de picão-preto (Bidens pilosa) e corda-de-viola (Ipomoea triloba). O herbicida foi aplicado utilizando pulverizador pressurizado por CO2, com pontas TT11002 espaçadas de 0,50 m, operando nas pressões de 100 kPa (gotas muito grossas) e 400 kPa (gotas médias) nos volumes de calda de 35, 70, 140 e 280 L ha-1, obtidos por meio da variação na velocidade de aplicação. No momento da aplicação foram avaliados a porcentagem de área coberta e a densidade de gotas (gotas cm-²) em etiquetas de papel hidrossensível, utilizando o programa DropScope®. Melhores índices de controle do picão-preto são obtidos quando a aplicação foi realizada com gotas muito grossas, na pressão de 100 kPa, com volume de calda entre 65 e 280 L ha-1, densidade de gotas superior a 60 gotas cm-2 e cobertura maior que 10%.

ABSTRACT The soil organic carbon (SOC) content under climate change scenarios is essential, especially in areas of difficult access such as the high-altitude Tropical paramos. This study aimed to correlate the digital elevation model (DEM) derivatives, spectral indices from Sentinel-1 and Sentinel-2, and WorldClim data with in situ SOC content in the PNR-Cortadera paramo (Boyaca, Colombia). Based on 169 soil samples collected at two depths (0-15 and 15-30 cm) organic carbon was determined using the Walkley-Black method. SOC contents ranged from 25 to 200 t HA-1 at 0-15 cm and from 33 to 466 t ha-1 at 15-30 cm. Altitude, temperature, NDVI, TWI0-15 cm, MRVBF, LS factor0-15 cm and VH band polarization showed the highest correlations and the lowest variance inflation factor. The highest SOC contents are located in the central and southern area of the paramo due to the higher altitude, greater precipitation and presence of vegetation cover.

RESUMEN El contenido de carbono orgánico (COS) del suelo bajo escenarios de cambio climático es esencial, especialmente en áreas de difícil acceso como los páramos tropicales de gran altitud. Este estudio tuvo como objetivo correlacionar los derivados del modelo de elevación digital (DEM), los índices espectrales Sentinel-1 y Sentinel-2 y los datos de WorldClim con el contenido de COS in situ en el páramo PNR-Cortadera (Boyacá, Colombia). A partir de 169 muestras de suelo recolectadas a dos profundidades (0-15 y 15-30 cm), se determinó el carbono orgánico mediante el método de Walkley-Black. Los contenidos de COS a 0-15 cm de profundidad variaron entre 25 a 200 t ha-1 y 33 a 466 t ha-1 a 15-30 cm. La altitud, la temperatura, el NDVI, el TWI0-15 cm, el MRVBF, el factor LS0-15 cm y la polarización de la banda VH mostraron las mejores correlaciones y el menor factor de inflación de la varianza. Los mayores contenidos de COS se ubican en la zona central y sur del páramo debido a la mayor altitud, precipitación y presencia de cobertura vegetal.
