Propagation of a Fatigue Crack Through a Hole.

The stop-hole technique is a well-known strategy to extend the fatigue life of cracked components. The ability to estimate fatigue life after the hole is important for safety reasons. The objective here is to develop strategies for the accurate prediction of initiation and propagation life ahead of the stop-hole.

Historical and future heat-related mortality in Portugal's Alentejo region.

Background: The increased severity of extreme weather and anticipated climate change has intensified heat stress-related mortality worldwide. This study examines the historical short-term effects of heat on mortality in Alentejo, Portugal's warmest region, and projects it up to the end of the century.

Methods: Using data from 1980 to 2015 during warm seasons (May-September), the association between daily mortality by all-causes and mean temperature was examined following a case time series design, applied at both regional and subregional scales.

Pooled prevalence of Escherichia coli phenotypic and genotypic antimicrobial resistance profiles in poultry: systematic review and meta-analysis.

Escherichia coli is a zoonotic bacterium, and its resistance to antimicrobials has become an increasing problem in global health. This study aimed to determine the phenotypic and genotypic pooled prevalence of E. coli with antimicrobial resistance profiles in poultry through systematic review and meta-analysis.

Metabolic Profiles of Critically Ill COVID-19 Patients: A Comparative Analysis of Energy Expenditure.

Introduction and aims The COVID-19 pandemic has placed a significant burden on healthcare systems worldwide, especially in the management of critically ill patients. Accurate assessment of energy expenditure (EE) is crucial for providing optimal nutritional support and improving clinical outcomes in these patients. Indirect calorimetry (IC) is the preferred method for measuring EE, yet its use in critically ill COVID-19 patients has not been extensively documented.

Longitudinal association of stress with mental health in the context of COVID-19: The mediating role of psychological flexibility and emotional schemas.

Stress is a known contributor to psychosocial pathological conditions and reduction of well-being. The literature has highlighted the role of emotional schemas and psychological flexibility as psychological processes underlying this relationship in the short term. This two-wave longitudinal study analyses the mediating role of psychological flexibility and emotional schemas in the relationship between stress responses to COVID-19-related events and mental health 6 months later.
