1. Quais as indicações para a eletroconvulsoterapia (ECT)?
A eletroconvulsoterapia (ECT) é um tratamento biológico que a partir de uma convulsão induzida propõe benefícios terapêuticos para alguns quadros de transtornos psiquiátricos. Os avanços na anestesia e equipamentos de estimulação elétrica, a utilização de eletrodos e as formas de pulso melhoraram os efeitos colaterais e a segurança no tratam

2. Catalysts Derived from Thermal Treatments of Hydrocalumite-Type Compounds: Synthesis and Application in Transesterification Reactions
Catalyst performance is a relevant factor in biodiesel production because it can affect the efficiency of the process. This work provides a study of the performance of heterogeneous catalysts for biodiesel production derived from thermal-treated hydrocalumite-type compounds. This work aimed to synthesize and characterize hydrocalumite-type compounds intercal

4. Phenolic Compounds from Leaves of Cariniana estrellensis (Raddi) Kuntze (Lecythidaceae): A Brazilian Atlantic Forest Tree
Cariniana estrellensis (Raddi) Kuntze seedlings have been used in forest restoration programs in the Atlantic Forest biome. However, despite the economic and ecological relevance of this species, to date no general method for rapid identification of primary and secondary metabolites of C. estrellensis leaves has been reported. In this work, we explore the fe

5. Different water availability in the economic water productivity in soybean cultivars
ABSTRACT The present work aims to evaluate grain productivity, water productivity, and economic water productivity of three soybean cultivars under supplementary irrigation. Two experiments were conducted during the 2018 and 2019 harvests in Santa Maria/RS, Brazil. The experimental design consisted of a random bifactorial block design with six irrigation dep

6. Physiology of the forage cactus cultivate Opuntia stricta (Haw.) Haw under different irrigation frequencies in the Semiarid
ABSTRACT The objective of this work was to evaluate the physiological variables of the cultivar Opuntia stricta (Haw.) Haw in the first cycle and in the regrowth, under different frequencies of drip irrigation, cultivated in the Agreste da Paraíba mesoregion. Therefore, a randomized block design was used, with 2 treatments (irrigation frequencies) and 4 rep

7. Bimetallic Au-Pd/α-MoO3 Catalyst with High Oxygen Vacancies for Selective Oxidation of Cinnamyl Alcohol
Supported Au-Pd nanoparticles (NPs) have been extensively studied in alcohol oxidation reactions. However, few studies use reducible metal oxides as support, which can activate oxygen molecules and boost the selectivity of the reaction. In this work, Au-Pd NPs were supported on α-MoO3 and evaluated in the selective oxidation of cinnamyl alcohol without solv

8. Characterization and variability of strains of Xanthomonas axonopodis pv. passiflorae from the state of Pará, Brazil
ABSTRACT Bacterial spot, caused by Xanthomonas axonopodis pv. passiflorae, is a disease that has limited the cultivation of passionfruit in various orchards in Brazil. The objective of this work is to characterize and evaluate the variability of 29 strains of X. axonopodis pv. passiflorae from different municipalities producing yellow passionfruit in the sta

9. Chromosome diversity in Buthidae and Chactidae scorpions from Brazilian fauna: Diploid number and distribution of repetitive DNA sequences
Abstract In this work, we analyzed cytogenetically eight Chactidae and Buthidae, including the localization of repetitive DNA sequences. The chactids possess monocentric chromosomes and the highest diploid numbers (2n=50 in Brotheas amazonicus, 2n=36 in Chactopsis amazonica, 2n=30 in Neochactas sp.) when compared with buthids (2n=10 in Tityus bahiensis, 2n=1

10. Organizational Culture and Performance-Based Compensation in Family Firms: Does Family Involvement in Management Matter?
Abstract Purpose This study aims to analyze how different types of organizational culture influence the implementation of performance-based compensation policies in family-owned micro, small and medium-sized enterprises (MSMEs) and whether the presence of the owning family in the management of the firm moderates this relationship. Theoretical framework Cam
