Lula in an X post shared a picture of himself smiling next to Padilha and his top foreign policy adviser, Celso Amorim, during a meeting on Monday.

Lula underwent fresh medical exams on Friday, which showed he is in “stable” condition after a fall that cause trauma to the back of his head, requiring stitches and resulting in a small brain hemorrhage.

Azul has reached a deal with its existing group of bondholders to obtain additional financing, the Brazilian airline said on Monday, as part of restructuring it expects to ease market concerns about its high debt load. Under the deal with bondholders, the carrier said in a securities filing that Azul will receive $150 million this week and another $250 million by year-end in fresh debt, totaling the $400 million it had been targeting. Reuters reported last week, citing sources, that Azul was in talks with multiple parties to raise about $400 million in fresh capital via debt financing and that an agreement was near.

Currently, Brazilian coffee farming seeks the rational use of resources through sustainable practices. As a result, the development of machinery with more efficient input application systems and the adoption of precision agriculture techniques have been yielding excellent results. This study was divided into two stages, with the first involving the adaptation of a solid fertilizer application machine with fixed doses, allowing dose variation using an electronic controller. The second stage consisted of conducting trials and their applications under operational conditions. The results confirmed that the developed system remained stable in terms of variable-rate fertilizer distribution for coffee cultivation. The machine's lateral fertilizer distribution range met the demands of coffee farming satisfactorily. In field conditions, the developed system exhibited an average error of −2.9%, compared to the programmed doses, validating the accuracy of the machine and its suitability for use in coffee plantations.

Traditional disease severity monitoring is subjective and inefficient. This study employs a Parrot multispectral sensor mounted on an unmanned aerial vehicle (UAV) to apply machine learning algorithms, such as random forest, for categorizing defoliation levels in R7-stage soybean plants. This research assesses the effectiveness of vegetation indices, spectral bands, and relative vegetation cover as input parameters, demonstrating that machine learning approaches combined with multispectral imagery can provide a more accurate and efficient assessment of Asian soybean rust in commercial soybean fields. The random forest algorithm exhibited satisfactory classification performance when compared to recent studies, achieving accuracy, precision, recall, F1-score, specificity, and AUC values of 0.94, 0.92, 0.92, 0.92, 0.97, and 0.97, respectively. The input variables identified as most important for the classification model were the WDRVI and MPRI indices, the red-edge and NIR bands, and relative vegetation cover, with the highest Gini importance index.
