Choking on small parts remains one of the leading causes of death and injury in infants and toddlers. The current method of testing for small parts, created by the Consumer Product Safety Commission (CPSC), has become outdated and has yet to be changed despite the many deaths and injuries of children. The method uses a device called the small parts test fixture (SPTF) that is supposed to mimic ...

Choked banana presents closeness of petioles looks that allows the exit distal part inflorescence, but not basal is stuck up at throat. The aim this study was to avaluate effect choking on growth Musa spp. cv Nanica, as well investigate how climatic variations and status nutritional plants are associated whith physiological disorder. experiment conducted in September/2018 August/2019 Registro, ...

Submodels are developed for injection, evaporation and wall impingement of a liquid LPG spray. The injection model determines the quality of fuel as two-phase choke flow at the nozzle exit. Wind tunnel experiments show the spray penetration more sensitive to ambient flow velocity than to injection pressure. Most evaporation occurs during choking, while heat transfer from surrounding air has a n...

The complex flow phenomena in a three-dimensional supersonic steam ejector were simulated with non-equilibrium condensation model including real physical properties different pressure conditions. working conditions include discharge pressure, motive and suction pressure. influence of pressures on shock waves the was investigated comprehensively. intrinsic causes wave variation explained detail....

There are three non-exclusive theoretical explanations for the paradoxical collapse of performance due to large financial incentives. It has been proposed that "choking under pressure" is either due to distraction, interference via an increase in top-down control and performance monitoring, or excessive levels of arousal in the face of large losses. Given the known neural architecture involved ...

BACKGROUND An increased risk of choking associated with antipsychotic medication has been repeatedly postulated. AIMS To examine this association in a large number of cases of choking deaths. METHOD Cases of individuals who had died because of choking were linked with a case register recording contacts with public mental health services. The actual and expected rates of psychiatric disorder...

In order to investigate the influence of typical hypervelocity gas effects on lubrication performance compliant foil face seal (CFFGS) end surfaces, gas–elastic coupling theory model CFFGS is modified by considering choked flow and inertia effect, solved using finite difference method. Based choking effect pressure field velocity analyzed, operating parameters mechanism change in dynamic sealin...

Blood flow in arteries is dominated by unsteady flow phenomena. The cardiovascular system is an internal flow loop with multiple branches in which a complex liquid circulates. A nondimensional frequency parameter, the Womersley number, governs the relationship between the unsteady and viscous forces. Normal arterial flow is laminar with secondary flows generated at curves and branches. The arte...
