Regional assessment of atmospheric CO₂, CH₄ and CO concentrations in Southern Brazil using WRF-Chem under present and energy transition scenarios

Abstract The objective of this study was to evaluate the spatial and temporal distribution of greenhouse gases (CO₂ and CH₄) and the atmospheric pollutant CO in Santa Catarina, Brazil, and to analyze the impacts of energy transition scenarios on their atmospheric concentrations....

Big five personality traits and lifestyle: a cross-sectional study in brazilian undergraduate students

Abstract Background Lifestyle psychiatry focuses on interventions targeting modifiable behaviors and has emerged as a key approach to promoting mental health. Personality traits are associated with a broad range of health-related behaviors. However, few studies have examined thei...

Analysis of Temperature Distribution in Steel-Concrete Composite Beams with Concrete Hollow Core Slabs with Rectangular Openings Under Fire Conditions

Abstract The structural contribution of slab in steel–concrete composite beams depends on the interaction between materials. Despite providing procedures for temperature evolution and strength reduction in composite beams with solid slabs, NBR 14,323 does not include specific rec...

Evaluation of sludge from water and sewage treatment plants as a landfill cover layer

Abstract The management of sludge from water and sewage treatment plants (WTP and STP, respectively) is still a challenge due to its high complexity and high costs. In that regard, this research proposes to evaluate the potential of using sewage sludge and water sludge as cover m...

Non-thermal plasma engineering of CuO/Cu2O nanostructures on copper mesh for tunable selectivity in electrochemical CO2 reduction

Abstract The rising levels of atmospheric CO₂ have exceeded the capacity of the natural carbon cycle, driving interest in electrocatalytic CO₂ reduction as an environmental and energy solution. Copper-based tandem electrocatalysts remain the most investigated catalysts due to the...

Small-world organization as a representation-dependent signature of nonlinear dynamics in biological time series

Abstract Small-world topology is usually interpreted in connectivity networks, but graphs derived from individual time series have different node and edge semantics. We examined how three common time-series representations—Quantile Graphs (QG), Gramian Angular Fields (GAF), and M...

From Nova food classification to policy implementation: Latin American lessons for the sustainable diets agenda

Latin America has become a major source of conceptual and evidence-informed policy innovation in response to the expansion of ultra-processed foods (UPFs).1–3 Although much of this processing-based policy architecture emerged through public health and food and nutrition security...

Andrographolide as a Promising Diterpenoid Scaffold Against the Neurotropic Nematode Angiostrongylus cantonensis

Background: Angiostrongylus cantonensis is a neurotropic nematode recognized as the leading cause of eosinophilic meningitis worldwide. Despite its growing medical importance, therapeutic options for angiostrongyliasis remain limited, highlighting the need for new anthelmintic ag...

The Fixation of Belief in Machines: Disciplined Contestation as an Alternative to Mutual Adversarial Oversight

Current approaches to artificial intelligence reliability are inspectional: opaque models are first trained, and their reliability is evaluated through interpretability, red-teaming, or oversight by equally opaque models. This generates an unaudited regress of overseers, as each...

Assessment of organizational readiness for implementing an online pain education program for chronic musculoskeletal pain in Brazilian public health context: a cross-sectional study

Understanding the organizational readiness for behavior change is paramount for implementation success of new interventions and to avoid waste of resources. To assess organizational readiness of primary healthcare providers to refer users with chronic musculoskeletal pain for an...

Construct Validity and Reliability of the OMNI Scale in Children and Adolescents With Neuromuscular Diseases

INTRODUCTION/AIMS: Children and adolescents with neuromuscular diseases often demonstrate muscle weakness and mobility limitations, which may increase perceived exertion during functional tasks. The OMNI scale was developed to assess perceived exertion in pediatric populations; h...

Postharvest Quality and Functional Stability of White-Fleshed Sweet Potatoes with Cactus Mucilage Coatings and Packaging

Abstract Edible coatings based on plant-derived biopolymers are promising tools to preserve the functional quality of fresh foods. Sweet potato is considered a functional food due to its bioactive compound content, although these attributes may be compromised during postharvest s...

Identifying Co‐Expressed lncRNAs Correlated With Traits of Interest in an Animal Model for Metabolic Diseases in Humans

Nutrigenomics investigates how nutrients modulate gene expression. Among them, fatty acids (FA) play important roles in regulating gene transcription, while long non-coding RNAs (lncRNAs) may be associated with gene regulation and metabolic diseases. This study aimed to analyze t...

Psychosocial and Sociodemographic Factors Associated with Perceived Barriers to Physical Activity in Patients Receiving Chemotherapy

AIM: To evaluate associations between psychosocial and sociodemographic factors and perceived barriers to physical activity among hospitalized patients receiving chemotherapy. MATERIALS AND METHODS: This cross-sectional study included 163 patients hospitalized for chemotherapy. A...

Multi-omics analysis reveals Protein Kinase A-associated regulatory remodeling during adaptation of Trichoderma reesei to lignocellulosic substrate

The filamentous fungus Trichoderma reesei is a major industrial source of holocellulolytic enzymes, and its response to complex carbon sources is regulated by nutrient-sensing mechanisms, including the cyclic adenosine monophosphate (cAMP)-protein kinase A (PKA) signaling pathway...

Light-Based Therapies for Metabolic Modulation of Mesenchymal Stem Cells in Regenerative Dentistry

Abstract Periodontal diseases and temporomandibular disorders are characterized by chronic inflammation and progressive destruction of supporting tissues, leading to functional and aesthetic impairments. In this context, regenerative dentistry has increasingly focused on minimall...

He who pays the piper calls the tune? Capital structure and ESG performance in emerging markets

Purpose This study analyzes the association between capital structure and the environmental, social, and governance (ESG) performance among companies in emerging markets. Design/methodology/approach Using data from the London Stock Exchange Group covering 24 emerging markets and...

Fractional counterpart of a higher-order abstract Cauchy problem

Abstract In this paper, we consider the fractional powers of a linear operator associated with a higher-order abstract Cauchy problem defined by a linear parabolic equation. We also characterize the domain of the fractional powers and discuss the solvability of the fractional equ...

Risk assessment of voltage violations during unintentional islanding events

The increasing penetration of distributed generators (DGs) has led to the proposal of fault ride-through (RT) requirements. These requirements enhance the reliability of the electrical system; however, reduce the sensitivity of anti-islanding protections, potentially exposing sen...
