ABSTRACT Peanut (Arachis hypogaea) is an important agricultural crop in Brazil, considered one of the most important oilseed crops cultivated. The use of fertilizer-solubilizing bacteria can mitigate salt stress. The objective of this study was to evaluate the gas exchange, growth, and water use efficiency of the peanut crop irrigated with brackish water under phosphate fertilization and inoculated with bacteria of the genus Bacillus sp. The experimental design used in this study was completely randomized, in a 4 × 2 × 2 factorial scheme, with 5 replicates, referring to the forms of fertilization (F1 - 0% phosphorus, F2 - 50% phosphorus, F3 - 100% phosphorus, and F4 - bovine biofertilizer), presence and absence of the inoculant and two levels of electrical conductivity of the irrigation water (ECw - 0.3 and 4.0 dS m-1). Fertilization with organic fertilizer (100% biofertilizer) and mineral fertilizer (50 and 100% phosphorus) associated with Bacillus sp. mitigated the damage caused by salt stress and promoted greater water use efficiency, chlorophyll index, internal CO2 concentration and stem diameter. The control treatment (without phosphate fertilization and without salt stress) and the application of Bacillus sp. promoted greater performance in net photosynthesis, transpiration rate, stomatal conductance, and plant height in peanut plants.

RESUMO O amendoim (Arachis hypogaea) é uma importante cultura agrícola no Brasil, considerada uma das mais importantes oleaginosas cultivadas. O uso de bactérias solubilizadoras de fertilizantes pode mitigar o estresse salino. O objetivo deste estudo foi avaliar as trocas gasosas, o crescimento e a eficiência do uso da água da cultura do amendoim irrigado com água salobra sob adubação fosfatada e inoculada com bactérias do gênero Bacillus sp. O delineamento experimental utilizado neste estudo foi inteiramente casualizado, em esquema fatorial 4 × 2 × 2, com 5 repetições, referente às formas de adubação (F1 - 0% fósforo, F2 - 50% fósforo, F3 - 100% fósforo e F4 - bovino biofertilizante), presença e ausência do inoculante e dois níveis de condutividade elétrica da água de irrigação (CEa - 0.3 e 4.0 dS m-1). As adubações com fertilizante orgânico (100% de biofertilizante) e mineral (50 e 100% de fósforo) associada a Bacillus sp. mitigou os danos causados pelo estresse salino e proporcionou maior eficiência no uso da água, índice de clorofila, concentração interna de CO2 e diâmetro do caule. O tratamento controle (sem adubação fosfatada e sem estresse salino) e a aplicação de Bacillus sp., promoveu maior desempenho na fotossíntese líquida, taxa de transpiração, condutância estomática e altura das plantas em plantas de amendoim.

ABSTRACT The use growth regulators from the cytokinins and auxins group has been shown to increase the productivity of certain crops, as they may be involved in the expression of plant sex, although little is known about the action of auxin IBA and cytokinin CPPU on the fruiting of squash, as well as the interaction between both, which makes this field of study promising. Thus, the objective of this study was to induce the fruiting in Atlas squash, by means of different forms of application and proportions of cytokinin and auxin and to evaluate their effects on the physical-chemical characteristics of the fruits. The treatments were composed of six proportions associated with growth regulators and of two forms of application. The experimental design was a randomized block design with four replicates. At 72 days after transplanting, growth and fruit quality analyses were performed. The behavior of the hormones is modulated by their concentration and place of application, and the effect may be beneficial or not. The proportions 50/50% via leaf and 75/25% via ovary were the ones that increased the growth and parameters of fruit quality. The application of CPPU via leaf at higher concentration in proportion decreases quality characteristics such as vitamin C, carotenoids and starch. crops sex squash both promising Thus physicalchemical physical chemical fruits replicates 7 transplanting performed not 5050 50 50/50 7525 75 25 75/25 C starch 505 5 50/5 752 2 75/2 50/ 75/

RESUMO O uso de reguladores de crescimento do grupo das citocininas e auxinas tem demonstrado aumentar a produtividade de algumas culturas, pois podem estar envolvidos na expressão do sexo da planta, embora pouco se saiba sobre a ação da auxina IBA e da citocinina CPPU na frutificação da abóbora, bem como a interação entre ambas, o que torna este campo de estudo promissor. Assim, o objetivo deste estudo foi induzir a frutificação em abóbora Atlas, por meio de diferentes formas de aplicação e proporções de citocinina e auxina e avaliar seus efeitos nas características físico-químicas dos frutos. Os tratamentos foram compostos por seis proporções associadas a reguladores de crescimento e duas formas de aplicação. O delineamento experimental foi em blocos casualizados com quatro repetições. Aos 72 dias após o transplante, foram realizadas análises de crescimento e qualidade dos frutos. O comportamento dos hormônios é modulado por sua concentração e local de aplicação, podendo o efeito ser benéfico ou não. As proporções 50/50% via folha e 75/25% via ovário foram as que aumentaram o crescimento e os parâmetros de qualidade dos frutos. A aplicação de CPPU via foliar em maior concentração em proporção diminui características de qualidade como vitamina C, carotenoides e amido. culturas planta ambas promissor Assim Atlas físicoquímicas físico químicas frutos repetições 7 transplante não 5050 50 50/50 7525 75 25 75/25 C amido 505 5 50/5 752 2 75/2 50/ 75/

Eugenia punicifolia (Kunth) DC. is a medicinal plant used to treat diseases related to oxidative processes. In this work, 1H nuclear magnetic resonance (NMR) spectroscopy and multivariate analysis have been employed to track the chemical changes and antioxidant activity of dimethyl sulfoxide (DMSO) extracts from E. punicifolia leaves over seasons. Principal component analysis (PCA) applied to 1H NMR allowed discriminating DMSO extracts from leaves collected in the dry and rainy seasons and pointed out sucrose, catechin, and epicatechin as responsible for separating dry season samples and quercetin, acid gallic, glucose, and fatty acids contributed for rainy samples grouping. Notably, antioxidant assays revealed that dry season extracts exhibited a higher radical scavenging capacity. When those compounds were submitted to partial least squares-discriminant analysis (PLS-DA) only sucrose and fatty acids presented variable importance projection (VIP) score > 1, both metabolites are related somehow to the defense mechanisms of the plant. This pilot study may suggest new experimental approaches for more effectively monitoring the spectrum-effect relationship of E. punicifolia leaf extracts.

ABSTRACT The study aimed to determine the evapotranspiration (ETc) of the mango cv. ‘Palmer’ over two productive cycles, analyzing water-use efficiency (WUE) and crop water productivity (CWP) to propose average crop coefficient (Kc) values for improving irrigation management under cultivation conditions in the Low-Middle São Francisco Valley. The study was conducted from July 2019 to May 2021 in a commercial ‘Palmer’ mango orchard in Petrolina, State of Pernambuco, Brazil. Micrometeorological data was collected throughout the experimental period. The crop evapotranspiration (ETc) was determined using Bowen ratio energy balance (BREB), and then the Kc, WUE, and CWP were determined. The highest ETc values occurred during the floral induction phase (5.14 ± 0.85 mm day-1), with a Kc of 0.85; however, the lowest values were observed during the fruit maturation phase (3.60 ± 0.73 mm day-1), with a Kc of 0.91. Average water consumption per cycle was 1445 mm, with a daily average of 4.39 mm day-1. WUE and CWP were 16.9 and 24.5 kg ha-1 mm-1, respectively. Average Kc values of 0.81, 0.76, 0.85, 0.90, 0.95, and 0.91 are recommended for the vegetative growth, rest period and shoot maturation, floral induction, flowering, fruit development, and fruit maturation phases, respectively.

Abstract: En | Text: En | PDF: En

The antifungal potential of volatile organic compounds (VOCs) produced by actinobacterial strains Streptomyces sp. (ACTB-77) and Amycolatopsis sp. (ACTB-290) from the rhizosphere of Caatinga plants against Colletotrichum musae was investigated. VOCs produced by these microorganisms (axenic and co-culture) were investigated using headspace-solid phase micro-extraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS). Although no exclusive VOC peaks were observed in the co-culture with ACTB-77, the same experiment involving ACTB-290 yielded five new peaks, including two identified alcohols, suggested as bioreductive products of the corresponding ketones by the fungus. Statistical analysis revealed that co-culture ACTB-77/C. musae has a closer similarity to the fungus than to the actinobacteria, while the co culture ACTB-290/C. musae showed closer similarity to the actinobacteria. These confirmed the more pronounced antifungal activity of the ACTB-290 strain, as observed in the fungus growth inhibition experiments. The antifungal activity of ACTB-290 was associated to its sulfur-containing metabolites, while linalool was suggested as responsible for the ACTB-77 activity.

Objective: To assess the adherence to a set of evidence-based recommendations to support mental health during the coronavirus disease 2019 (COVID-19) pandemic and its association with depressive and anxiety symptoms. Methods: A team of health workers and researchers prepared the recommendations, formatted into three volumes (1: COVID-19 prevention; 2: Healthy habits; 3: Biological clock and sleep). Participants were randomized to receive only Volume 1 (control), Volumes 1 and 2, Volumes 1 and 3, or all volumes. We used a convenience sample of Portuguese-speaking participants over age 18 years. An online survey consisting of sociodemographic and behavioral questionnaires and mental health instruments (Patient Health Questionnaire-9 [PHQ-9] and Generalized Anxiety Disorder-7 [GAD-7]) was administered. At 14 and 28 days later, participants were invited to complete follow-up surveys, which also included questions regarding adherence to the recommendations. A total of 409 participants completed the study – mostly young adult women holding university degrees. Results: The set of recommendations contained in Volumes 2 and 3 was effective in protecting mental health, as suggested by significant associations of adherence with PHQ-9 and GAD-7 scores (reflecting anxiety and depression symptoms, respectively). Conclusion: The recommendations developed in this study could be useful to prevent negative mental health effects in the context of the pandemic and beyond.

Abstract The use of β-galactosidase in food products has been a major focus of the industry. Therefore, the development of efficient and inexpensive methodologies to purify it is essential. Thus, this study aimed to recover the enzyme β-galactosidase (β-gal) by ion-exchange chromatography in a fixed-bed column. Batch adsorption tests were performed using four types of adsorbents. The β-gal adsorption capacity in batch mode using Streamline DEAE resin presented the best performance, with a retention capacity of 18.77 ± 0.14 U/g at pH 6.0. A 22 experimental design was applied to optimize the β-gal recovery using an AKTA Start system, evaluating the ionic strength and the pH as process parameters. The results showed that ionic strength exerted a greater influence on fold purification (FP). The β-gal fraction in elution using 0.1-0.4 M of NaCl showed a yield of 51.65 ± 0.17% and FP of 2.00 ± 0.43. Electrophoresis confirmed the β-gal recovery, where an evident band with a molecular weight between 60 and 120 kDa was observed. These results point to the recovery of a stable β-gal of K. lactis with potential industrial applications.

Abstract The main objective of this study is to propose different probabilistic models for adjusting the trend component, since it significantly influences the quality of the spatio-temporal interpolation of rainfalls. We used the monthly total precipitation data of the São Francisco River Basin (SFRB) for the period of 31 years, 1989–2019. The SFRB occupies 8% of the whole Brazilian territory, mostly located in the Northeast Brazilian region. For the trend component, we propose the fitted GAMLSS models by comparing different probability distribution families, which in most cases include the characteristics of these data. The results indicate the existence of a spatio-temporal pattern of the residues obtained from the adjustment of the trend with zero adjusted Gamma distribution for the accumulated monthly precipitation. The adjustment revealed a spatial dependence of up to 873 km between the pluviometric stations and temporal autocorrelation of approximately 1.6 months. The methodology used in this study enabled us to create rainfall maps, interpolating unobserved locations in differences years. The projection of these maps to the SFRB is considered extremely important for planning and implementing activities related to water resources across the river basin.

Plant phenolic extracts are widely recognized as an important source of natural antioxidant substances and potential compounds for cosmetic formulations. This study aimed to evaluate the chemical profile, photoprotective and antioxidant activities of stem bark extract of Spondias purpurea L. (ciriguela) and its application in photoprotective formulations. Thirty phenolic constituents were annotated by ultra-performance liquid chromatography coupled with an electrospray ionization quadrupole time-of-flight mass spectrometry in mode negative (UPLC-QTOF-MS2). The stem bark extract antioxidant and chelation potential, expressed in half maximal inhibitory concentration (IC50), showed 6.25 and 352.22 µg mL−1, respectively. The phenolic extract was used as an active ingredient in six sunscreen formulations, with concentrations ranging from 0.2 to 10%. The ultraviolet (UV) protection properties of the formulations were evaluated by sun protection factor (SPF) values obtained in 0.2 mg mL−1 (0.495 to 2.27) and 2.0 mg mL−1 (2.29 to 15.87). The SPF value for the extract (14.37 and 26.16) was high, but there was a reduction in the base formulation. However, these results suggested that the bioactive extracted of stem bark of Spondias purpurea L. has interesting potential to reduce the damage caused by UV radiation and may be utilized as an active ingredient in a sunscreen formulation.

Abstract BINGO (BAO from Integrated Neutral Gas Observations) is a unique radio telescope designed to map the intensity of neutral hydrogen distribution at cosmological distances, making the first detection of Baryon Acoustic Oscillations (BAO) in the frequency band 980 MHz - 1260 MHz, corresponding to a redshift range 0.127 < z < 0.449. BAO is one of the most powerful probes of cosmological parameters and BINGO was designed to detect the BAO signal to a level that makes it possible to put new constraints on the equation of state of dark energy. The telescope will be built in Paraíba, Brazil and consists of two \thicksim 40m mirrors, a feedhorn array of 50 horns, and no moving parts, working as a drift-scan instrument. It will cover a 15 ^{\circ} ∘ declination strip centered at \sim \delta ∼ δ =-15 ^{\circ} ∘, mapping \sim ∼ 5400 square degrees in the sky. The BINGO consortium is led by University of São Paulo with co-leadership at National Institute for Space Research and Campina Grande Federal University (Brazil). Telescope subsystems have already been fabricated and tested, and the dish and structure fabrication are expected to start in late 2020, as well as the road and terrain preparation.

RESUMO Esse estudo objetivou avaliar sazonalmente a histomorfometria do epidídimo de Dermanura cinerea (Gervais, 1856) em um fragmento de Mata Atlântica no nordeste do Brasil. Foram utilizados 18 espécimes machos adultos capturados por redes de neblina. As coletas ocorreram mensalmente ao longo de dezoito meses, durante duas noites consecutivas e os dados meteorológicos foram fornecidos pelo Instituto Nacional de Meteorologia. Depois de eutanasiados, os espécimes tiveram os epidídimos coletados e esses órgãos foram fixados e processados. As lâminas histológicas foram coradas por Hematoxilina - Eosina e analisadas em microscopia óptica. Os parâmetros morfométricos analisados foram as áreas do túbulo, do lúmen e do epitélio das regiões do segmento inicial, cabeça, corpo e cauda do epidídimo. Os dados histomorfométricos obtidos foram submetidos às análises no teste U de Mann-Whitney. Os resultados revelaram que D. cinerea apresentou espermatozoides em todas as regiões do epidídimo, exceto no segmento inicial. As maiores médias das áreas tubular, do lúmen e do epitélio nas quatro regiões, foram constatadas durante os meses secos. Portanto, D cinerea apresentou maior sensibilidade na região da cauda do epidídimo, ao longo dos meses com baixos índices pluviométricos. Isso indica que as condições ambientais apresentam considerável influência sobre a morfofisiologia epidídimária dessa espécie, sobretudo, em relação ao armazenamento de espermatozoides na cauda desse órgão, em área de Mata atlântica do nordeste brasileiro.

ABSTRACT Description and seasonal variation in epididymal histomorphometry of Dermanuracinerea (Chiroptera: Phyllostomidae) in a fragment of the Atlantic Forest in the Northeastern Brazil. This study aimed to evaluate seasonal patterns in the histomorphometry of the epididymis of Dermanura cinerea (Gervais, 1856) in a fragment of the Atlantic Forest in the Northeastern Brazil. Eighteen adult male specimens captured by mist net were used. The field-work occurred monthly over 18 months, during two consecutive nights. Meteorological data (precipitation) were obtained from the National Institute of Meteorology. After euthanasia, specimens had the epididymis collected, which were fixed and processed. The histological slides produced were stained by Hematoxylin - Eosin and analyzed by optical microscopy. The morphometric parameters analyzed were the tubular, lumen and epithelium areas, of the regions of the initial segment, caput, corpus and cauda of the epididymis. The histomorphometric data were submitted to the Mann-Whitney U test analyzes. The results showed that D. cinerea presented spermatozoa in all regions of the epididymis, except in the initial segment. The highest averages of the tubular, lumen and epithelial areas in the four regions were observed during the dry months. Therefore, D cinerea presented greater sensibility in the region of the cauda of the epididymis, during the months with low rainfall indices. This indicates that environmental conditions have considerable influence on the epididymal morphophysiology of this species, especially in relation to the storage of sperm in the tail of this organ, in area of Atlantic forest in northeastern Brazil.

NEW HYBRID NANOSTRUCTURED ADSORBENT TYPE AMINE/KIT-6 FOR CO2 CAPTURE. The present work functionalized KIT-6 mesoporous material with aminopropyltrimethoxysilane (APTMS) and tested its efficiency in CO2 capture. The KIT-6 material was synthesized by hydrothermal method and functionalized via excess solvent in APTMS concentrations of 5 and 15% to obtain the hybrid adsorbents. All adsorbent materials were characterized by XRD, TGA/DTGA, DSC, N2 adsorption/desorption, SEM and applied in the CO2 capture, varying the temperature and pressure. The KIT-6 mesoporous structure at the hybrid adsorbents was kept. Variations in textural properties denoted that the organic molecules were incorporated in mesoporous structure. In the experiments, both chemisorption and physisorption were observed, reaching the best values at 25 ºC, indicating that the temperature influences the adsorption process. The experiments showed adsorbed amounts of up to 0.8 mmol/g at atmospheric pressure, displaying the efficiency of the chemisorption provided by the CO2 interaction with the hybrid adsorbents. At high pressures, a predominance of physisorption was observed, demonstrating a better performance for the KIT-6 support, due to the superior textural properties. Finally, a well-ordered and functional hybrid adsorbent was successfully developed for the adsorption of carbon dioxide.

RESUMO Objetivou-se avaliar a emergência, o crescimento, o acúmulo de biomassa e a tolerância de genótipos de amendoim sob estresse salino. O experimento foi desenvolvido em ambiente protegido (casa de vegetação), avaliando seis genótipos de amendoim (Tatuí, L7151, Caiapó, IAC8112, IAC881 e Havana) submetidos a dois níveis de salinidade da água de irrigação (0,5 (controle) e 3,5 dS m-1), arranjados em esquema fatorial 6 x 2, em delineamento experimental de blocos casualizado, com cinco repetições, com duas plantas por parcela. As plantas foram cultivadas durante 30 dias após a semeadura, em lisímetros com capacidade para 0,5 dm3, preenchidos com uma mistura de solo não salino e não sódico, com substrato comercial na proporção de 1:1 base em volume. Durante esse período as plantas foram avaliadas quanto à emergência, crescimento, acúmulo de biomassa e tolerância à salinidade e dissimilaridade. Os genótipos Tatuí e L7151 são os mais sensíveis ao estresse salino na fase de emergência. A irrigação com água de alta salinidade reduziu o crescimento, o acúmulo de biomassa dos genótipos de amendoim, sendo os genótipos Caiapó e IAC8112 os menos afetados. A classificação de tolerância à salinidade teve a seguinte sequência: Caiapó > IAC8112 > Havana > Tatuí > IAC881 > L7151.

ABSTRACT This study aimed to evaluate the emergence, growth, biomass accumulation and tolerance of peanut genotypes under salt stress. The experiment was conducted in a protected environment (greenhouse), evaluating six peanut genotypes (Tatuí, L7151, Caiapó, IAC8112, IAC881 and Havana), which were subjected to two levels of irrigation water salinity (0.5 [control] and 3.5 dS m-1), arranged in a 6 x 2 factorial scheme, in a randomized block design, with five repetitions, with two plants per plot. Plants were cultivated for 30 days after sowing in lysimeters with capacity for 0.5 dm3, filled with a mixture of non-saline, non-sodic soil and commercial substrate in 1:1 proportion on volume basis. During this period, plants were evaluated for emergence, growth, biomass accumulation, tolerance to salinity and dissimilarity. The genotypes Tatuí and L7151 are the most sensitive to salt stress in the emergence stage. Irrigation with high-salinity water reduced the growth and biomass accumulation of the peanut genotypes, and Caiapó and IAC8112 were the least affected. The classification of salinity tolerance had the following sequence: Caiapó > IAC8112 > Havana > Tatuí > IAC881 > L7151.

Campomanesia adamantium é uma espécie nativa do Cerrado brasileiro com potencial de utilização na alimentação humana, medicina fitoterápica e indústria de bebidas. Este trabalho foi desenvolvido com o objetivo de caracterizar o processo de embebição e a emissão da raiz primária das sementes de C. adamantium em diferentes temperaturas. Após a despolpa, as sementes foram submetidas à determinação do teor de água e caracterização inicial da qualidade fisiológica. Para avaliar o efeito da temperatura na embebição das sementes estas foram expostas a 20, 25 e 30 °C e posteriormente foram registados a massa de sementes e número de sementes com emissão da raiz primária a intervalos pré-estabelecidos. Foi ajustado modelo de Peleg aos dados de embebição e bandas de 95% de confiança foram construídas para comparação estatística das curvas. A embebição à temperatura de 30 °C foi significativamente mais rápida que a 20, 25 ºC. O modelo de Peleg foi eficiente para descrever o processo de absorção de água pelas sementes. Altas temperaturas (30 °C) favorecem a rápida embebição e protrusão da raiz primária em sementes de C. adamantium. A fase II do processo de embebição em sementes desta espécie é curta e a fase III não é bem definida pela alta absorção de água.

Campomanesia adamantium is a native Brazilian Cerrado species with potential for use in human food, herbal medicine and the beverage industry. This work was developed in order to characterize the process of soaking and primary root protrusion of C. adamantium seeds at different temperatures. After pulp removal, seeds were evaluated for water content and initial characterization of the physiological quality. To study the soaking process, the seeds were exposed at temperatures of 20, 25 and 30 °C and then, data of seed mass and number of seeds with primary root protrusion were obtained at pre-established intervals. Peleg’s model was fitted to the soaking data and 95% confidence bands were constructed for statistical comparison of the curves. The soaking at the temperature of 30 ° C was significantly faster than at the other temperatures. The Peleg’s model was efficient to describe the process of water absorption of the seeds. High temperatures (30 ° C) favor the rapid imbibition and primary root protrusion in C. adamantium seeds. Phase II of the seed imbibing process of this species is short and phase III is not well defined by high water uptake.
