The rate-limiting mechanism for the heterogeneous burning of iron in normal gravity and reduced gravity [PDF]

open access: yes, 2007
This thesis presents a research project in the field of oxygen system fire safety relating to the heterogeneous burning of iron in normal gravity and reduced gravity. Fires involving metallic components in oxygen systems often occur, with devastating and

17O burning rate in star: A revision [PDF]

open access: yesEPJ Web of Conferences
When stars approach the red giant branch, a deep convective envelope develops and the products of the CNO cycle appear at the stellar surface. In particular, the 17O is enhanced in RGB and AGB stars.

Burning Rate Enhancement Analysis of End-Burning Solid Propellant Grains Based on X-Ray Real-Time Radiography

open access: yesInternational Journal of Aerospace Engineering, 2020
Unexpected pressure rise may occur in the end-burning grain solid rocket motor. It is generally believed that this phenomenon is caused by the nonparallel layer combustion of the burning surface, resulting in the increase of burning rate along the ...

The Gut–Heart Axis in Systemic Sclerosis: Evidence From a Large Prospective Early Disease Cohort

open access: yesArthritis Care &Research, EarlyView.
Objective Cardiac involvement significantly impacts prognosis in systemic sclerosis (SSc), highlighting the need for early risk stratification. Gastrointestinal (GI) symptoms are common and often manifest early. Emerging data suggest a link between GI and cardiac manifestations, possibly through shared mechanisms like dysautonomia.

Influence of high altitude on the burning behaviour of typical combustibles and the related responses of smoke detectors in compartments [PDF]

open access: yesRoyal Society Open Science, 2018
The effect of altitude on typical combustible burning and related smoke detector response signals was investigated by comparison experiments at altitudes of 40 m and 3650 m based on EN54 standard tests.

Facial Cosmetic Therapy Use Among Patients With Systemic Sclerosis: An Australian Cohort Study

open access: yesArthritis Care &Research, EarlyView.
Objective Systemic sclerosis (SSc) is associated with numerous facial manifestations for which patients may engage in cosmetic therapies. It is unclear how patients with SSc use these therapies. This study sought to characterize patient engagement and experiences with cosmetic therapies for SSc‐related and non‐SSc–related facial changes.

Extending Service Beyond Active Duty: Generalizability of Rheumatoid Arthritis Research Conducted Among US Veterans

open access: yesArthritis Care &Research, EarlyView.
Biomedical research involving US veterans continues to advance health care beyond the Veterans Health Administration. This is particularly true in rheumatoid arthritis (RA), where veteran‐centric research has uncovered novel insights into pathogenesis, risk factors, and disease manifestations, informing clinical care and research across both veteran ...

Effect of body material and temperature variation on the performance of the time delay pyrotechnic compositions

open access: yesDefence Technology, 2018
Significance of body material and temperature variation on burning time and burning rate of Si/PbO/Pb3O4/FG and B/BaCrO4/FG pyrotechnic delay compositions were experimentally studied. Brass and stainless steel were used as delay body materials.

Survival Outcomes in Older Adults with Axial Spondyloarthritis and Concomitant Cancer

open access: yesArthritis Care &Research, Accepted Article.
Objective The objective of this study was to determine survival outcomes in older adults with axial spondyloarthritis (axSpA) and concomitant cancer. Methods We conducted a population‐based study using Medicare claims data linked to Surveillance, Epidemiology, and End Results data to determine overall survival (OS) and cancer‐specific survival (CSS) in

Determining the Burning Rate of Fine-Grained Propellants in Closed Vessel Tests

open access: yesEnergies, 2022
This paper presents the method of determining the burning rate of fine-grained propellants based on the results of closed vessel tests. It is shown that in the case of fine-grained propellants, the standard methods of determining the burning rate fail ...
