Two‐dimensional guillotine cutting problem for large objects with non‐rectangular shapes

Abstract In this paper, we address the two‐dimensional single large object placement problem with guillotine cutting constraints, focusing on non‐rectangular shapes. We consider objects with circular or convex polygonal geometries and study a variant that includes defective regio...

Temporal changes in estuarine water quality during decentralized wastewater treatment implementation in the Paranaguá estuarine system, southern Brazil

This study investigates the temporal response of estuarine water quality to progressive implementation of decentralized wastewater treatment systems (DWWTS) in Eufrasina, a traditional community within the Paranaguá Estuarine System (PES), southern Brazil. Monthly monitoring was...

Ligation of the canine mesovarium with a resorbable self-locking device: a multicentre study

Abstract Background Haemorrhage from the ovarian pedicle is a known complication at removal of ovaries in dogs. A resorbable self-locking device designed for surgical ligation was previously developed, aimed to keep the advantage of a self-locking loop at ligation and avoid the c...

Macroscopic and ultrasonographic anatomy of the brachial plexus in the American kestrel (Falco sparverius)

The American kestrel (Falco sparverius) is a small raptor frequently admitted to wildlife rehabilitation centers, often due to traumatic injuries requiring surgical intervention. Regional anesthesia techniques, particularly brachial plexus blocks, may improve perioperative manage...

Self-assessed palliative care competency acquisition across academic cycles among Brazilian medical students: a cross-sectional study

Palliative care (PC) supports individuals with life-limiting conditions by enhancing the quality of life for both patients and their families. Although international guidelines recommend PC training during medical school, Brazilian students often receive insufficient preparation...

Critical levels and sufficiency ranges of phosphorus in Pinus taeda plantations in southern Brazil

Pinus taeda plantations in South America have been cultivated on soils of low natural fertility, especially phosphorus (P), increasing the necessity for phosphate fertilisation. The proposition of critical levels (CL) and sufficiency ranges (SR) of P in the needles and soil in P....

Top-Degree global solvability for tube complexes in gevrey ultradistributions

Abstract Let $$s>1$$ s > 1 , let $$M$$ M be a connected, non-compact, oriented real-analytic manifold, and let $$\omega _1,\ldots ,\omega _m$$ ω 1 , … , ω m be real-valued closed 1-forms of Gevrey order s on M . We study the differential complex naturally associated with this fam...

Proposed Economic Threshold for Diceraeus melacanthus (Dallas) in Maize Under an Early Intercrop Cultivation System

Abstract The Antecipe® system, in which maize is sown between soybean rows while soybean plants are still in the reproductive stage, reduces the production cycle of the soybean-maize crop system and, consequently, mitigate climatic risk for second-crop maize. However, the coexist...

Optimizing the Production of a Condensed Tannin-Based Bioflocculant for Toxic Metal Remediation

Abstract Conventional water treatment typically employs chemical coagulants and flocculants, such as aluminum sulfate and iron salts. However, the intensive use of these products can lead to negative environmental impacts and pose significant health risks. In this context, bioflo...

Spectrum of Neuroimaging Findings in CNS Lymphoproliferative Disorders

Central nervous system (CNS) lymphoproliferative disorders comprise a heterogeneous group of rare entities that present major diagnostic and therapeutic challenges. Primary CNS large B-cell lymphoma (LBCL) is the most common form and the second most frequent primary CNS tumor aft...

Socioeconomic inequalities in sleep disturbances among school-aged children: evidence from socioeconomically vulnerable schools

Abstract Background Family socioeconomic inequalities have been consistently associated with children’s sleep disturbances. However, it remains unclear whether these inequalities are equally evident among children attending socioeconomically vulnerable schools, where many environ...

Comparison of alkali-silica reaction mitigation between supersulfated cement and Portland cement

Deleterious alkali-silica reaction (ASR) in concrete occurs between alkaline ions and reactive minerals present in aggregates. Studies with Portland cement (PC) have shown that alumina can help form a protective film that surrounds the aggregate and hinders the dissolution of rea...

Oxygen-Vacancy-Controlled Band-Gap Engineering in Fe/Co Co-doped La-Modified Bismuth Titanate: Integrated Experimental and First-Principles Analysis

Abstract Layered Aurivillius ferroelectrics offer a route to multifunctional band-gap engineering, yet the role of oxygen vacancies in band-edge reconstruction in Fe/Co-modified compositions remains poorly resolved. Here, oxygen annealing of Bi3.25La0.75Ti2.60(Fe0.50,Co0.50)0.40O...

MAURO BOIANOVSKY: AN EXEMPLARY SCHOLAR

This study introduces the late Mauro Boianovsky (1959–2024), one of the most distinguished historians of economics of his generation. Drawing on interviews and correspondence with his colleagues, co-authors, former students, and his sister, the study offers a portrait of his acad...

Green Chemistry Oriented Pluronic F127/Carbopol Nanogel Platform (NGLp) Encapsulating Lippia pedunculosa Essential Oil for Aedes aegypti Larval Control

Abstract Control of Aedes aegypti larvae is essential to reduce arbovirus transmission; however, increasing insecticide resistance and environmental concerns highlight the urgent need for sustainable alternatives. In this study, a solvent-free thermoresponsive nanogel (NGLp), bas...

Heat sink fins design based on the Constructal Law: a CFD approach for air-cooled electronic devices
