Engineering Reports, Volume 8, Issue 1, January 2026.A Pearson correlation coefficient of 0.60 indicates a moderately positive linear relationship exists between the two variables. The correlation coefficient (r) can take a value ranging between −1 and 1. A significant correlation, which does not occur randomly, will use the p value to determine statistical significance of the correlation coefficient ...

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.Abstract Silicon carbide (SiC) is a promising material for hypersonic thermal protection systems, but its complex oxidation behavior—marked by transitions between passive, active, and interfacial bubbling regimes—can lead to catastrophic failure. Existing SiC models typically focus exclusively on either passive or active oxidation.

Meteoritics &Planetary Science, Volume 61, Issue 1, Page 122-139, January 2026.Abstract The O‐, N‐, Mo‐, Ru‐, Os‐, Cr‐, Ti‐, Ni‐, Fe‐, Nd‐, Ca‐, Zn‐, Sr‐, and Mg‐isotopic compositions of enstatite chondrites are essentially identical to those of the Earth and Moon. These correspondences suggest enstatite chondrites formed at ≈1 AU as the only known chondrite groups that accreted in the vicinity of a major planet. Bulk Earth has a

Geofluids, Volume 2026, Issue 1, 2026.The development of low‐permeability reservoirs in the South China Sea X Oilfield is frequently hindered by severe compaction damage zones induced by conventional shaped charge perforation, which significantly impair well productivity. To mitigate these adverse effects, novel self‐cleaning and aftereffect perforation technologies have been proposed ...

International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.This study is aimed at addressing combustion instability phenomena observed during the operation of dual‐burn‐rate Solid Rocket Motors (SRM) with a large aspect ratio. Previously, the acoustic mode of the combustion chamber (induced by external excitation) and the vortex shedding frequency were typically analyzed independently, and the probability of ...

Mehran University Research Journal of Engineering and Technology, 2019 Optimum characteristic length of the combustion chamber of liquid rocket engine is very important to get higher energy from the liquid propellants. Characteristic length is defined by the time required for complete burning of fuel.
