    Currently, there is big market pressure for raw materials like lithium (Li) that has driven new satellite image applications for Li exploration. However, there are no reference spectra for petalite (a Li-mineral) in large, open spectral datasets. In this work, a spectral library was built exclusively dedicated to Li-minerals and Li-pegmatite exploration through satellite remote sensing. The database includes field and laboratory spectra collected in the Fregeneda-Almendra region (Spain-Portugal) from (i) distinct Li-minerals (spodumene, petalite, lepidolite); (ii) several Li-pegmatites and other outcropping lithologies to allow satellite-based lithological mapping; (iii) areas previously misclassified as Li-pegmatites using machine learning algorithms to allow comparisons between these regions and the target areas. The potential future uses of this spectral library are reinforced by its major advantages: (i) data is provided in a universal file format; (ii) it allows to compare field and laboratory spectra; (iii) a large number of complementary data allows the comparison of shape, asymmetry, and depth of the absorptions features of the distinct Li-minerals. The peer-reviewed data descriptor for this dataset has now been published in MDPI Data - an open access journal aiming at enhancing data transparency and reusability, and can be accessed here: https://www.mdpi.com/2306-5729/6/3/33.

    ABSTRACT: Knowledge of the distribution of total phosphorus (P) content in native soils provides information on the management of ecosystem, land capability for agriculture, environmental quality, and biodiversity conservation. We mapped the spatial distribution of total P concentrations in topsoils (0-30 cm) of uncultivated (native) areas in Brazil. We obtained data on native total P of the southern, south-eastern, and north-eastern regions from reports of exploratory projects developed between 1960s and 1970s by EMBRAPA and by the RADAM Brazil Project. We estimated data from the central-western and northern regions from the relationship between total P and soil properties (Fe, Al, C and clay content), based on the RADAM Brazil Project. Soil total P varied widely (< 25 to > 500 mg kg–1) in all regions in Brazil. Higher concentrations (> 500 mg kg–1) were observed in southern region compared to most of the rest of the country (< 200 mg kg–1), while the Cerrado (Central), Amazon (North) and Caatinga (Northeast) biomes are very poor in total P. This first national native soil total P map provides a valuable baseline for understanding the historical patterns of agriculture expansion in Brazil. It allows quantifying the effect of agriculture expansion and future cropping systems on soil available P content and legacy P, targeting regional soil-crop specific strategies for optimization of ecosystem services, and mitigating potential environmental risk due to P transference to water bodies.

    ABSTRACT: Brazil nut is a typical oilseed from the Amazon region, of great economic and cultural importance. Due to its high nutritional value, it is interesting to be used as a matrix for new products’ development. Thus, the present study aimed to develop and characterize a drink based on Brazil nuts fermented by Lactobacillus casei and added with inulin. After formulated, the drink was pasteurized, fermented, maturated, and stored under refrigeration for 28 days. Physical, chemical, microbiological, and sensory analyzes were performed before and after fermentation, at 7-day intervals. There was maintenance in the content of lipids and proteins and reduction in the concentrations of fibers, ash, total carbohydrates, and moisture. The fermented drink pH decreased significantly during storage, while the acidity and the soluble solids content increased from the 14th day. Regarding the color, there were significant changes in all parameters analyzed. In the fermented drink, the development of molds and yeasts, total and thermotolerant coliforms, and Salmonella were not verified, while the control drink deteriorated after 7 days. The probiotic L. casei had count ranging from 9.48 to 8.59 log CFU mL-1 during the 28 days. When exposed to in vitro gastrointestinal conditions, L. casei significantly reduced its concentration. However, it reached the enteric phase with counts greater than 6.00 log UFC mL-1. Sensorially, the drink reached intermediate scores (between 5.41 and 6.02). Therefore, the use of Brazil nuts proved to be viable for the development of a product free of animal-origin components, symbiotic, and of outstanding nutritional quality.

    Abstract The objective of this work is to analyze the annual variation and the effects of the atmospheric variability mode El Niño (Canonical and Modoki) on the concentration of the Total Ozone Column (TOC) on the NEB between 1997 and 2018 using data generated by the sensors Total Ozone Mapping Spectrometer (TOMS) and Ozone Monitoring Instrument (OMI). An average monthly variation was observed, with typical behavior of the annual cycle domain in the seasonal variability, presenting a minimum value in May and maximum in October. There was a declining trend in the series of average values for the entire area. Cluster analysis revealed that different regions of the study area have slightly different behaviors and mean values of the total ozone column. Wavelet analysis was used, which exposed cycles of twelve months in length throughout the studied area, six-month cycles, demonstrating that the semi-annual cycle dominates seasonal variability in lower latitudes, and also two to three years cycles, representing the important performance of the Quasi-Biennial Oscillation (QBO). Anomaly averages show that El Niño events affect TOC causing predominantly a decrease in their values. These Modoki events have a greater potential to affect TOC variations than canonical events, with negative anomalies of greater intensity.

    ABSTRACT: Knowledge of the distribution of total phosphorus (P) content in native soils provides information on the management of ecosystem, land capability for agriculture, environmental quality, and biodiversity conservation. We mapped the spatial distribution of total P concentrations in topsoils (0-30 cm) of uncultivated (native) areas in Brazil. We obtained data on native total P of the southern, south-eastern, and north-eastern regions from reports of exploratory projects developed between 1960s and 1970s by EMBRAPA and by the RADAM Brazil Project. We estimated data from the central-western and northern regions from the relationship between total P and soil properties (Fe, Al, C and clay content), based on the RADAM Brazil Project. Soil total P varied widely (< 25 to > 500 mg kg–1) in all regions in Brazil. Higher concentrations (> 500 mg kg–1) were observed in southern region compared to most of the rest of the country (< 200 mg kg–1), while the Cerrado (Central), Amazon (North) and Caatinga (Northeast) biomes are very poor in total P. This first national native soil total P map provides a valuable baseline for understanding the historical patterns of agriculture expansion in Brazil. It allows quantifying the effect of agriculture expansion and future cropping systems on soil available P content and legacy P, targeting regional soil-crop specific strategies for optimization of ecosystem services, and mitigating potential environmental risk due to P transference to water bodies.

    ABSTRACT: Brazil nut is a typical oilseed from the Amazon region, of great economic and cultural importance. Due to its high nutritional value, it is interesting to be used as a matrix for new products’ development. Thus, the present study aimed to develop and characterize a drink based on Brazil nuts fermented by Lactobacillus casei and added with inulin. After formulated, the drink was pasteurized, fermented, maturated, and stored under refrigeration for 28 days. Physical, chemical, microbiological, and sensory analyzes were performed before and after fermentation, at 7-day intervals. There was maintenance in the content of lipids and proteins and reduction in the concentrations of fibers, ash, total carbohydrates, and moisture. The fermented drink pH decreased significantly during storage, while the acidity and the soluble solids content increased from the 14th day. Regarding the color, there were significant changes in all parameters analyzed. In the fermented drink, the development of molds and yeasts, total and thermotolerant coliforms, and Salmonella were not verified, while the control drink deteriorated after 7 days. The probiotic L. casei had count ranging from 9.48 to 8.59 log CFU mL-1 during the 28 days. When exposed to in vitro gastrointestinal conditions, L. casei significantly reduced its concentration. However, it reached the enteric phase with counts greater than 6.00 log UFC mL-1. Sensorially, the drink reached intermediate scores (between 5.41 and 6.02). Therefore, the use of Brazil nuts proved to be viable for the development of a product free of animal-origin components, symbiotic, and of outstanding nutritional quality.

    Abstract The objective of this work is to analyze the annual variation and the effects of the atmospheric variability mode El Niño (Canonical and Modoki) on the concentration of the Total Ozone Column (TOC) on the NEB between 1997 and 2018 using data generated by the sensors Total Ozone Mapping Spectrometer (TOMS) and Ozone Monitoring Instrument (OMI). An average monthly variation was observed, with typical behavior of the annual cycle domain in the seasonal variability, presenting a minimum value in May and maximum in October. There was a declining trend in the series of average values for the entire area. Cluster analysis revealed that different regions of the study area have slightly different behaviors and mean values of the total ozone column. Wavelet analysis was used, which exposed cycles of twelve months in length throughout the studied area, six-month cycles, demonstrating that the semi-annual cycle dominates seasonal variability in lower latitudes, and also two to three years cycles, representing the important performance of the Quasi-Biennial Oscillation (QBO). Anomaly averages show that El Niño events affect TOC causing predominantly a decrease in their values. These Modoki events have a greater potential to affect TOC variations than canonical events, with negative anomalies of greater intensity.
