Repeated cross-sectional study of knowledge and use of wild food plants in the Caatinga of Northeastern Brazil

Wild Food Plants (WFPs) are important for food and cultural security. Despite a global trend of erosion in WFP knowledge, little is known about how people perceive their relationship with these species. This study analyzes how WFP knowledge has changed over time, and how ecologic...

Effect of Combined Pelvic Floor and Inspiratory Muscle Training in Women with Stress Urinary Incontinence Associated with Chronic Obstructive Pulmonary Disease: Study Protocol for a Randomized Controlled Trial

Abstract Chronic Obstructive Pulmonary Disease (COPD) is associated with respiratory muscle weakness and chronic cough, increasing intra-abdominal pressure and contributing to the development of stress urinary incontinence (SUI) in women. Although pelvic floor muscle training (PF...

What is the pediatric sport framework, and how can it be applied in professional practice?

Abstract Youth sport development during childhood and adolescence requires models that integrate multidimensional domains of knowledge and respect biological maturation across both conventional sports and para-sports. However, contemporary environments prioritizing immediate perf...

Machine learning–based screening tool for predicting the risk of oropharyngeal dysphagia in patients with ischemic stroke

Abstract Purpose Dysphagia frequently complicates recovery after stroke, necessitating effective predictive tools. This study aimed to develop supervised machine learning models to predict dysphagia risk in ischemic stroke patients. Method We retrospectively analyzed data from 10...

Performance of the mixed compression intake system of a scramjet demonstrator at different off-design flight speeds

Abstract This paper focuses on the numerical investigation of the effects of flight speed fluctuations on the intake system performance of the scramjet demonstrator developed in the Universidade Federal do Rio Grande do Norte (UFRN). A set of 2D-RANS simulations based on equation...

Computational and experimental evaluation of bismuth modification in CsPbX3 (X = I− or Br−): Impact on structural and optical properties

In this work, the effects of partial substitution of Pb 2+ by Bi 3+ at the B-site of CsPbI 3 and CsPbBr 3 perovskites on their structural and optical properties were evaluated using an integrated approach combining Density Functional Theory (DFT) calculations and experimental res...
