Methodology for Optimizing Structural Masonry Positioning and Width to Minimize Lateral Displacements in Buildings under Earthquakes via the CIOA

Abstract Seismic loads can induce significant lateral displacements that compromise the stability and safety of buildings. One effective strategy to mitigate these effects is the use of masonry infills, modeled as diagonal truss elements, to enhance the lateral stiffness of the s...

Rheological, Viscoelastic, and Dynamic Mechanical Behavior of ZnO-Filled and MA-Modified PP/SEBS Filaments for Fused Filament Fabrication

Abstract Immiscible polyolefin–elastomer blends often exhibit limited impact resistance and unstable melt-flow behavior due to weak interfacial adhesion and inefficient stress transfer between phases. These limitations are relevant for fused filament fabrication (FFF), where fila...

Methodological Quality and Overlap of Systematic Reviews Comparing Carotid Endarterectomy versus Carotid Artery Stenting in Symptomatic Contralateral Carotid Occlusion: An Overview of Reviews

Background: Symptomatic contralateral carotid occlusion (CCO) is considered a high-risk scenario for carotid revascularization, yet the comparative evidence for carotid endarterectomy (CEA) versus carotid artery stenting (CAS) is largely derived from observational data and repeat...

Balancing culture and strategy: challenges in Brazilian conventional deterrence

The relationship between strategic culture and conventional deterrence has been predominantly examined through cases in which cultural factors reinforce deterrent effectiveness. This article argues that strategic culture can also constrain and fragment deterrence, producing subop...

Occurrence of Stenotrophomonas carrying β-lactamase-encoding genes in a veterinary hospital environment

Abstract Stenotrophomonas spp. are environmental bacteria increasingly recognized as opportunistic pathogens with multidrug resistance. This study characterized 17 environmental Stenotrophomonas isolates recovered from effluent samples and veterinary hospitalization units. The sp...

Vitrification-Controlled Curing of Epoxidized Linseed Oil Resins: Kinetics, TTT Analysis, and Thermomechanical Performance with Anhydride and Amine Curing Agents

Abstract Epoxidized linseed oil (ELO) is a promising biobased alternative to petrochemical epoxy precursors, with a curing behavior strongly influenced by the chemistry of the curing agent and the resulting network architecture. In this study, ELO was synthesized via the Shi epox...

Behavioral, Psychological, and Metabolic Characteristics of Adults with Co-Occurring Generalized Anxiety Disorder and Obesity: A Cross-Sectional Study

Background: Generalized Anxiety Disorder (GAD) and obesity are highly prevalent and often co-occur, yet it remains unclear how the presence of both conditions relates to biological, behavioral, and psychological outcomes compared with either condition alone. Understanding this su...

Customer influence on value delivery in agricultural product development: the Brazilian farmers' perspective

Purpose This study aims to quantify the value delivery attributes of an innovative model of grain drying machine, focusing on its potential to enhance sustainability and efficiency in Brazilian agriculture. Design/methodology/approach This study employs a mixed-method approach, i...

Erector Spinae Block in Bariatric Surgery: a Systematic Review and Meta-Analysis of Randomized Controlled Trials

Abstract Introduction Obesity is a growing global health issue, and bariatric surgery offers effective weight loss outcomes. Postoperative pain management remains a challenge, with multimodal analgesia and regional blocks like the erector spinae plane (ESPB) showing promise. This...

Performance-based durability assessment of concrete containing coal bottom ash as fine aggregate under chloride penetration

Abstract The use of industrial wastes represents an alternative for reducing the consumption of natural aggregates in concrete production. Coal bottom ash (CBA), a byproduct of coal combustion in thermal power plants, has been employed as a partial replacement for fine aggregates...

Heat Transfer Enhancement in a Shell-and-Tube Type of Heat Exchanger Using Al2O3/Water Nanofluid

Abstract Shell-and-tube heat exchangers are widely used in industrial processes, but improving the shell-side heat transfer without causing excessive pressure losses remains a major engineering challenge. Numerical simulations provide an efficient approach for evaluating thermohy...

Habitat is more important than management for fruit-feeding butterfly assemblages in family-farm agricultural systems

Abstract Agricultural expansion is a primary cause of biodiversity decline, as it leads to habitat loss and fragmentation. In contrast, small organic systems or agroforestry are considered sustainable means of production. However, the impact of management class (conventional or o...

Salivary and serum levels of NT-proBNP, troponin, and high-sensitivity C-reactive protein in patients with heart failure

Background Saliva has been proposed as a non-invasive biological matrix for cardiovascular biomarker assessment. However, evidence regarding its agreement with blood-based measurements in patients with heart failure remains inconsistent. Objective To assess the presence of NT-pro...

The annual cycle activities of birds from Serra da Mantiqueira, Brazil

Abstract The timing of feather molting and breeding, two key activities in the avian life cycle, varies widely among species. These variations are shaped by each species’ unique ecological traits and their interactions with dissimilar environmental factors, such as seasonal chang...

Climatic niche divergence in the diversification of long-haired mice of the subgenus Abrothrix (Cricetidae: Abrotrichini)

Abstract Advances in methods integrating phylogenetic information into climatic niche characterization have enabled a more explicit assessment of ecological factors in lineage diversification. Using these approaches, the climatic niches of long-haired mice of the subgenus Abrothr...

The Value of Becoming Actual: Antinatalism, Cosmic Meaning, and Ontological Natal Permissibilism

Abstract David Benatar’s antinatalism holds that coming into existence is always a harm and that procreation is therefore morally impermissible. This article develops a non-theistic alternative to a recent supernaturalist response to Benatar offered by Wakeman and Launonen. It de...

From glow to risk: degree of exposure of Arctiinae moths (Lepidoptera: Erebidae) to light pollution in the Neotropics

Abstract The accelerated decline of insects is driven by anthropogenic pressures such as habitat loss, pesticide use, and climate change. Species vulnerability varies according to their exposure, sensitivity, and adaptive capacity to these threats. Artificial light at night (ALAN...
