Servo-stabilization of combustion in rocket motors [PDF]
, 1952 This paper shows that the combustion in the rocket motor can be stabilized against any value of time lag in combustion by a feedback servo link from a chamber pressure pickup, through an appropriately designed amplifier, to a control capacitance on the ...

Impact of Environmental Exposure on Infant Sleep : The Exposome Approach
Journal of Sleep Research, EarlyView.This review explores how exposure to environmental pollutants during the first 1000 days of life may affect infant sleep. Evidence suggests potential links between chemical exposures and sleep disturbances, underscoring the need for more research on early‐life vulnerability and the impact of pollutants in air, diet, and breast milk.

Do deepfakes, digital replicas and human digital twins justify personality rights?
The Journal of World Intellectual Property, EarlyView.Abstract Unauthorised deepfakes are deeply problematic, from the spreading of misinformation to non‐consensual pornographic content. This paper asks whether deepfakes, digital replicas and human digital twins justify personality rights. To address this question, it examines the harms that deepfakes can cause through disinformation, demeaning content ...

Effective Mechanical Property Estimation of Composite Solid Propellants Based on VCFEM
International Journal of Aerospace Engineering, 2018 A solid rocket motor is one of the critical components of solid missiles, and its life and reliability mostly depend on the mechanical behavior of a composite solid propellant (CSP).

Studies in Ethnicity and Nationalism, EarlyView.ABSTRACT This article examines the Turkish state's Village Guard system, revived in the 1980s as part of its counterinsurgency strategy against the Kurdistan Workers Party (PKK). While often framed as a defensive militia, the Village Guards became central to the state's exceptional governance in Kurdistan, both facilitating military control and ...

Performance of advanced composite solid rocket propellants based on novel oxidizers
IOP Conference Series: Materials Science and Engineering, 2019 Abstract Three novel high energy dense oxidizers (HEDO), Bis(2,2,2-trinitroethyl)oxalate (BTNEOx), 2,2,2-Trinitroethyl-nitrocarbamate (TNENC), 2,2,2-Trinitroethyl-formate (TNEF) have been prepared and studied as oxidizers in composite solid rocket propellants (CSRPs).

Terrestrial Analogs to Titan for Geophysical Research
Reviews of Geophysics, Volume 64, Issue 2, June 2026.Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...
