The Canadian Journal of Chemical Engineering, Volume 102, Issue 7, Page 2418-2431, July 2024.Abstract This research delved into the effects of introducing multi‐walled carbon nanotubes (MWCNTs) and sodium dodecyl sulphate (SDS) into crude oil with an anionic base, aiming to enhance its thermophysical attributes in the EOR process. The investigation encompassed a range of properties, including interfacial tension, viscosity, density, and ...

Thermal expansion of the earth and the speed of neutrinos [PDF]
arXiv, 2011 It is pointed out that one of the systematic effects that can affect the measurement of the speed of neutrinos significantly is the variability of the unaveraged measurement of the distance between two points on the earth due to thermal expansion. Possible difference between estimates done with surface GPS apparatus and the true underground baseline ...

Constraints on neutrino and dark radiation interactions using cosmological observations
, 2012 Observations of the cosmic microwave background (CMB) and large-scale structure (LSS) provide a unique opportunity to explore the fundamental properties of the constituents that compose the cosmic dark radiation background (CDRB), of which the three ...

Maternal &Child Nutrition, Volume 20, Issue 3, July 2024.We conducted a real‐world prospective nonrandomized study assessing the noninferiority of a nonweight‐based daily ready‐to‐use therapeutic food dosage for the treatment of severe acute malnutrition in children under 5, when compared to the standard weight‐based daily dosage. Our results confirm the noninferiority of this dosage as an alternative to the

New solar metallicity measurements
, 2019 In the past years, a systematic downward revision of the metallicity of the Sun has led to the "solar modeling problem", namely the disagreement between predictions of standard solar models and inferences from helioseismology.

Journal of Geophysical Research: Space Physics, Volume 129, Issue 5, May 2024.Abstract Terrestrial Gamma Ray Flashes (TGFs) are short bursts of gamma rays occurring during thunderstorms. They are believed to be produced by Relativistic Runaway Electron Avalanches (RREAs). In this paper, we present a new numerical model based on the Particle‐In‐Cell (PIC) method to simulate the interactions between the electromagnetic fields and ...

Neutrino Velocity and the Variability of Fundamental Constants [PDF]
, 2012 Neutrino speed experiments could be viewed not only as tests of Lorentz invariance but also as measurements of limiting propagation speed for all standard model species below certain depth where no direct metrological information is available. The latter option, hypothetically caused by some chameleon-type background, could be tested in the next ...

Asymptotically‐Flat Black Hole Solutions in Symmergent Gravity
Fortschritte der Physik, Volume 72, Issue 4, April 2024.Abstract Symmergent gravity is an emergent gravity model with an R+R2$R+R^2$ curvature sector and an extended particle sector having new particles beyond the known ones. With constant scalar curvature, asymptotically flat black hole solutions are known to have no sensitivity to the quadratic curvature term (coefficient of R2$R^2$). With variable scalar

Neutrino Anisotropies after Planck
, 2013 We present new constraints on the rest-frame sound speed, c_{eff}^2, and the viscosity parameter, c_{vis}^2, of the Cosmic Neutrino Background from the recent measurements of the Cosmic Microwave Background anisotropies provided by the Planck satellite ...

Effects of Forbush Decreases on the Global Electric Circuit
Space Weather, Volume 22, Issue 4, April 2024.Abstract The suppression of high‐energy cosmic rays, known as Forbush decreases (FDs), represents a promising factor in influencing the global electric circuit (GEC) system. Researchers have delved into these effects by examining variations, often disruptive, of the potential gradient (PG) in ground‐based measurements taken in fair weather regions.
