Linear Programming Optimization of Nutritional and Technological Properties in Wheat Bread Fortified With Taioba (Xanthosoma sagittifolium L.) Leaf Flour

Cereal Chemistry, Volume 103, Issue 5, Page 754-766, September/October 2026.
ABSTRACT Background and Objectives This study applied linear programming to optimize taioba (Xanthosoma sagittifolium) leaf flour (TLF) incorporation in wheat bread, balancing nutritional enrichment and technological quality. Findings Breads containing 0%–15% TLF (flour basis) were produced and evaluated for composition, dough expansion, specific ...

Signatures of equatorial plasma bubbles in VHF satellite scintillations and equatorial ionograms [PDF]

Radio Science, 2013
Since their discovery in the 1970s, equatorial plasma bubbles (EPBs) have been invoked to explain the propagation of VHF signals on trans‐equatorial circuits at night, and blamed for highly detrimental scintillation of VHF and GHz trans‐ionospheric communications signals in equatorial regions.

Monitoring of equatorial plasma bubbles using aeronautical navigation system: a feasibility study

Earth, Planets and Space, 2023
It has long been known that field-aligned irregularities within equatorial plasma bubbles (EPBs) can cause long-range propagation of radio waves in the VHF frequencies such as those used for TV broadcasting through the so-called forward scattering ...

Topotactic Nitridation Enabled Core–Shell La4Ti3(O,N)12@LaTiO2N for Efficient Photoelectrochemical Water Splitting

Small, Volume 22, Issue 49, 1 September 2026.
Topotactic nitridation of (111)‐plane layered perovskite La4Ti3O12 proceeds through a persistent 2D layered oxynitride La4Ti3(O,N)12, enabling formation of a core–shell La4Ti3(O,N)12@LaTiO2N heterostructure before full conversion into 3D perovskite LaTiO2N.

Analytical Modeling of Hot Ion Interchange Injections in Saturn's Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Cassini's CHarge Energy Mass Spectrometer (CHEMS) instrument collected energetic plasma data from 2004 to 2017, including hundreds of observations of small‐scale nearly dispersionless “local” injection events into the inner magnetosphere. This study assesses whether these interchange‐like injections are a channel‐like structure still connected

The Occurrence Climatology of Equatorial Plasma Bubbles: A Review

Journal of Astronomy and Space Sciences, 2022
Electron density irregularities in the equatorial ionosphere at night are understood in terms of plasma bubbles, which are produced by the transport of low-density plasma from the bottomside of the F region to the topside. Equatorial plasma bubbles (EPBs) have been detected by various techniques on the ground and ...
