A total of 72 one-day-old male Cobb 500® chicks were assigned to a completely randomized design with two treatments: diets containing 7.5% HPDDG, with or without β-mannanase. Performance was evaluated at 7 and 14 d. At the same periods, apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), and metabolizability coefficients were determined. At 14 d, one bird per replicate was selected for blood collection for serum biochemical analysis, intestinal permeability assessment, SCFA (acetic and butyric acids) determination on cecal content, and pancreatic (amylase, lipase, trypsin, and chymotrypsin) and intestinal disaccharidase (maltase and sucrase) activity analyses. Data were subjected to analysis of variance after verification of residual normality by the Shapiro–Wilk test, adopting a 5% significance level. No differences (P>0.05) were observed between treatments for performance, energy values, intestinal permeability, enzyme activities, serum biochemical parameters, or SCFA profile. However, βmannanase supplementation resulted in a numerical increase of 53 kcal kg⁻¹ in AME. It is concluded that β-mannanase supplementation in diets containing HP-DDG does not affect performance or physiological parameters of broilers during the starter phase.

Rather than reconstructing the author’s biography or describing the empirical functioning of psychiatric institutions, the study approaches the literary work as a historically situated symbolic elaboration, in which subjective experiences, medical discourses, and gender norms intersect. The central problem is to understand how the narrative constructs madness as a female experience shaped by contradictory social expectations, while also examining how psychiatry appears in the novel both as a space of care and as a dispositif of normalization and social reintegration. Methodologically, the research conducts a historical-literary analysis of selected passages from the novel, confronting them with entries from Plath’s journals not as factual confirmation, but as interpretative support for understanding the processes of subjectivation at stake. It argues that Esther Greenwood’s madness is not presented as an isolated pathology, but as the result of tensions between individual aspirations, gender roles, and institutional dispositifs regulating femininity in the period. By problematizing the notion of cure, the study highlights the limits of psychiatric recovery as a functional return to a social order that continues to produce suffering. Thus, this research contributes to the historical understanding of the relationships between gender, subjectivity, and psychiatric knowledge, as well as to debates on the medicalization of female distress in the second half of the twentieth century. At the same time, it illuminates central aspects of Sylvia Plath’s trajectory, marked by experiences of loss, academic pressure, marital tensions, and rigidly gendered social expectations. Her biography is not mobilized as a causal or reductive explanation of her literary production, but as a field of symbolic disputes in which medical discourses, norms of femininity, and strategies of selfelaboration intertwine. In this sense, the analysis of her life allows for an understanding of how her experience was simultaneously singular and historically situated, revealing the tensions between creation, suffering, and the dispositifs of power that act upon the female body and subjectivity.

Unlike important previous studies, this work considers the concurrent occurrence of these two modes of climate variability, including combinations with the same sign and with opposite signs across all ENSO typologies (Eastern, Central, and Mixed). To obtain the results, the IOD phases were initially identified using the Dipole Mode Index (DMI), while the ENSO phases were identified through the Oceanic Niño Index (ONI). The impacts on precipitation over SEAS were assessed using rainfall anomaly composites. To understand the mechanisms associated with these anomalies, composite maps of geopotential height anomalies at 200 hPa and omega anomalies at 200 hPa and 500 hPa were also produced. The results first revealed a predominance of combinations between ENSO and IOD events with the same sign, particularly in the Mixed ENSO typology. Another noteworthy finding was the absence of co-occurrence between Eastern and Central El Niño events with negative IOD (IOD-) events. The dissertation hypothesis — that ENSO effects over SEAS would be stronger when combined with IOD phases of the same sign — was partially confirmed. Events such as Eastern El Niño and Eastern La Niña indeed showed intensified effects when associated with IOD phases of the same sign. However, opposite-sign combinations between the modes, such as Mixed El Niño with IOD-, Central La Niña with IOD+, and Mixed La Niña with IOD+, proved to be more effective in terms of the intensity of impacts over SEAS. Another relevant result was observed in the combination of Central La Niña and IOD-, which produced intense positive precipitation anomalies over SEAS, indicating that, in this case, the Indian Ocean interannual mode outweighed the ENSO effects.

The application of bioinputs based on plant growth-promoting microorganisms represents a potential alternative for improving rooting efficiency. This study was conducted to evaluate, in two experiments, the rooting capacity of olive cultivars using microbial biostimulants and the effect of different biostimulants on seedling development during the nursery phase. The first experiment, focused on cutting rooting, was carried out in October using four olive cultivars: Arbequina, Maria da Fé, Ascolano 315, and Koroneiki. Cuttings were prepared and placed in masonry beds containing sand as substrate under controlled humidity and temperature conditions. The experimental design was completely randomized in a 6 × 4 factorial scheme (six biostimulants × four cultivars), with four replications and 25 cuttings per replication, totaling 100 cuttings per treatment. In addition to the control treatment (T1, IBA only), treatments consisted of biostimulants associated with IBA, including three Bacillus species: Bacillus amyloliquefaciens (T2), Bacillus licheniformis (T3), Bacillus subtilis (T4), Trichoderma harzianum (T5), and the commercial rooting product Bioraiz® (T6), all applied in liquid form to the substrate. Solutions were prepared according to the manufacturers’ recommendations, with a final volume of 3000 mL per treatment. Evaluations included rooting percentage, callus formation, and root system characteristics. The results indicated that the application of biostimulants enhanced rooting, with responses varying among cultivars. Increased rooting percentages were observed in the cultivars Maria da Fé, Ascolano 315, and Arbequina when treated with Trichoderma harzianum and Bacillus spp. Callus formation, particularly in Arbequina, was greater in the presence of Trichoderma harzianum, suggesting that this microorganism induces physiological processes related to rhizogenesis and improves root emission. The second experiment was conducted using olive seedlings approximately one year old, derived from the rooting phase and maintained under 70% shading. The experimental design was completely randomized in a 4 × 4 factorial scheme (cultivars × biostimulants), with three replications per treatment and two plants per replication. Plant height, stem diameter, and SPAD index were measured monthly over four months. Destructive analyses were performed to determine fresh and dry biomass of shoots and roots. The results demonstrated that seedling responses to biostimulants depended on genotype and the type of product applied, indicating interaction between cultivar and treatment. The use of seaweed extract proved promising for cultivars such as Ascolano 315, promoting greater initial growth and root system expansion. The use of microbial bioinputs can contribute to improved rooting of cuttings and enhanced growth of olive seedlings under nursery conditions.
