Analysis of Gravity Disturbance Compensation for Initial Alignment of INS
IEEE Access, 2020 To address the accuracy requirements of initial alignment of high-precision inertial navigation systems (INSs), gravity disturbance compensation for INSs based on a spherical harmonic model is investigated herein.

Effects of Reduced Gravity on Nucleate Boiling
Bulletin of JSME, 1969 An experimental study was conducted of the effects of reduced gravity on the mechanism of nucleate boiling, using a drop tower method with high speed motion pictures and a telemeter equipment. Within the range of reduced gravity up to 0.082g, the normal nucleate boiling was observed to be insensitive to gravity, having almost the same frequency of ...

Changes in Immune‐Inflammation Status and Prognosis in Pregnancy‐Related Cerebral Venous Thrombosis
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Distinguishing pathological changes from physiological adaptations in pregnancy‐related cerebral venous thrombosis (CVT) is clinically challenging. This study aimed to characterize coagulation, immune‐inflammation, and dehydration status in these patients and assess their prognostic value.

, 2010 The observable universe could be a 1+3-surface (the “brane”) embedded in a 1+3+d-dimensional spacetime (the “bulk”), with Standard Model particles and fields trapped on the brane while gravity is free to access the bulk.

La Soufriere Volcanic Eruptions Launched Gravity Waves Into Space [PDF]
, 2022 Atmospheric gravity waves can be excited by explosive volcanic eruptions and may reach Earth's upper atmosphere. In this study, we report on mesoscale concentric gravity waves observed in the mesopause airglow layer following the La Soufriere volcano ...

Combustion of Methanol Droplets in Air-Diluent Environments with Reduced and Normal Gravity
Journal of Combustion, 2012 Reduced and normal gravity combustion experiments were performed with fiber-supported methanol droplets with initial diameters in the 1 mm size range. Experiments were performed with air-diluent mixtures at about 0.101 MPa and 298 K, where carbon dioxide,

Arthritis Care &Research, EarlyView.Objective Studies of damage accrual in patients with systemic lupus erythematosus (SLE) show associations with disease activity measured by the SLE Disease Activity Index 2000 (SLEDAI‐2K), but these associations are imperfect. SLEDAI scores are powerfully influenced by weightings (1–8) assigned to each domain.

Life, 2014 The reduced-gravity environment in space is known to cause an upward shift in body fluids and thus require cardiovascular adaptations in astronauts. In this study, we recorded in rats the neuronal activity in the subthalamic cerebrovasodilator area (SVA),

Analytical Study on Gas-Oil Separation of a Heat Pump System under Lunar Gravity
Advances in Mechanical Engineering, 2020 A heat pump in the aerospace industry can significantly reduce the area of radiator by elevating the rejection temperature. Especially for a Lunar base, the heat pump can improve the heat rejection capability of the thermal control system to adapt the ...

Arthritis Care &Research, Accepted Article.Objective We examined associations of post‐traumatic stress disorder (PTSD) and other mental health disorders (OMH) with rheumatoid arthritis (RA), accounting for effects of smoking. Methods We conducted a matched case‐control study, identifying incident RA cases and controls using national Veteran Health Administration data (2006‐2019).
