Possible Indications of Variations in the Directionality of Beta-Decay Products
Frontiers in Physics, 2021 Some experiments seem to yield strong evidence of variability of beta-decay rates, but other experiments may show little or no such evidence. Some recent experiments help clarify the situation.

Radial gradient of the solar rotation rate in the near-surface shear layer of the Sun
Frontiers in Astronomy and Space Sciences, 2022 We study the radial gradient of the solar rotation rate in the near-surface shear layer (NSSL) from about .950 R⊙ to the solar surface and its variation during Solar Cycles 23 and 24 with ring-diagram analysis applied to Global Oscillation Network Group (

The Astrophysical Journal, 2023 Previous studies analyzing the evanescent nature of acoustic waves in the lower solar atmosphere, up to 300 km above the photosphere, have shown an unexpected phase shift of an order of 1 s between different heights.

Orbital dynamics of earth-orbiting 'smart dust' spacecraft under the effects of solar radiation pressure and aerodynamic drag [PDF]
, 2010 This paper investigates how the perturbations due to asymmetric solar radiation pressure, in presence of Earth's shadow, and atmospheric drag can be balanced to obtain long-lived Earth centered orbits for swarms of SpaceChips, without the use of active ...

Magneto-Rossby Waves and Seismology of Solar Interior
Frontiers in Astronomy and Space Sciences, 2018 Eleven-year Schwabe cycle in solar activity is not yet fully understood despite of its almost two century discovery. It is generally interpreted as owing to some sort of magnetic dynamo operating below or inside the convection zone.

Reducing interior temperature resulting from solar energy using three-dimensional surface patterns
Advances in Mechanical Engineering, 2015 Excessive solar energy can significantly increase interior temperatures and yield great energy demands for air conditioning. Whereas reducing energy consumptions is very crucial today, this article employs patterned glass technology which incorporates ...

Parameterization Studies of Solar Chimneys in the Tropics
Energies, 2013 The paper examines the effect of the solar chimney’s stack height, depth, width and inlet position on the interior performance (air temperature and speed at 1.20 m height above the ground) as well as proposes an optimal tropical solar chimney ...

Aproveitamento térmico de coletor solar na desinfestação de substrato
Revista Verde de Agroecologia e Desenvolvimento Sustentável, 2021 A desinfestação do substrato torna-se obrigatória na produção de mudas sadias e com vigor. No entanto, o tratamento convencional com agroquímicos pode ser insatisfatório, devido aos custos e aos riscos de vácuo biológico e intoxicação.

Orbital dynamics of high area-to-mass ratio spacecraft with J2 and solar radiation pressure for novel Earth observation and communication services [PDF]
, 2012 This paper investigates the effect of planetary oblateness and solar radiation pressure on the orbits of high area-to-mass spacecraft. A planar Hamiltonian model shows the existence of equilibrium orbits with the orbit apogee pointing towards or away ...
