Social determinants, conflict, and displacement: reframing oral health in humanitarian action [PDF]

Frontiers in Public Health
Oral health is a fundamental component of overall health, yet it remains chronically excluded from humanitarian response frameworks. Displaced populations, including refugees and internally displaced persons (IDPs), experience a disproportionate burden ...

Atypical amniotic fluid embolism presenting with isolated coagulopathy: a case report [PDF]

BMC Pregnancy and Childbirth
Background Amniotic fluid embolism (AFE) is a rare but catastrophic obstetric complication characterised by the sudden entry of amniotic fluid or fetal components into the maternal circulation, triggering severe cardiorespiratory collapse, coagulopathy ...

Analysis of steel frame under selected accidental situation [PDF]

Archives of Civil Engineering, 2022
The current design codes recommend designing the building structures based on the assumption avoiding the disproportionate to the initial cause damage during accidental situation.

Microbiome interactions and their ecological implications at the Salton Sea

California Agriculture, 2022
Although the Salton Sea was once a thriving destination for humans and wildlife, it has now degraded to the point of ecosystem collapse. Increases in local dust emissions have introduced aeolian (wind-blown) microorganisms that travel, along with ...

Numerical Study of Progressive Collapse in Intermediate Moment Resisting Reinforced Concrete Frame Due to Column Removal [PDF]

Civil Engineering Infrastructures Journal, 2014
Progressive collapse is a chain reaction of failures propagating throughout a portion of the structure disproportionate to the original local failure occurring when a sudden loss of a critical load‐bearing element initiates a structural element failure ...

A Generalized Framework for the Alternate Load Path Redundancy Analysis of Steel Truss Bridges Subjected to Sudden Member Loss Scenarios

Buildings, 2022
Owing to their distinct features, such as structural simplicity and excellent load-carrying capacity, steel truss bridges are widely applied as critical transportation networks.

Obstructive sleep apnoea is associated with dynamic intra-thoracic central airway collapse: results of a 10-year multi-centre retrospective analysis

Sleep Science and Practice, 2020
Background Disproportionate bulging of the pars membranosa into the central airway on expiration, now termed ‘excessive dynamic airway collapse’ (EDAC), has poorly characterised significance.

Performance Assessment of an Energy–Based Approximation Method for the Dynamic Capacity of RC Frames Subjected to Sudden Column Removal Scenarios

Applied Sciences, 2021
The alternative load path method is widely used to assess the progressive collapse performance of reinforced concrete structures. As an alternative to an accurate non–linear dynamic analysis, an energy–based method (EBM) can also be adopted to ...

A Modified Catenary Model with Application to the Analysis and Design of Retrofit Cables for Progressive Collapse

Infrastructures, 2018
Progressive collapse, the extensive or complete collapse of a structure resulting from the failure of one or a small number of structural components, has become a focus of research efforts and design considerations following events occurring at the Ronan

Experimental Investigation of Progressive Collapse of Prestressed Concrete Frames after the Loss of Middle Column

Advances in Civil Engineering, 2020
Accidental loads such as explosion and vehicle impact could lead to failure of one or several load-bearing members in the structures, which is likely to trigger disproportionate progressive collapse of overall structures.
