Geodesic infinitesimal deformations of generalized Riemannian space
(Birkhaeuser Verlag AG, 2022-05-11)
Infinitesimal deformations of subspaces of a generalized Riemannian
space are studied in this paper. Variations of some geometric
objects are found. Necessary and sufficient conditions which provide the
existence of a ...
Synthesis, characterization, hydrolytic, and thermal stability of urea–formaldehyde composites based on modified montmorillonite K10
(Springer, 2022-02-11)
In this study, the thermal and hydrolytic properties of composite systems based on the urea–formaldehyde resin (UF) and eco-friendly montmorillonite (K10) as formaldehyde (FA) scavenger were examined. UF resin with molar ...
Thermal behavior of gamma-irradiated urea-formaldehyde composites based on the differently activated montmorillonite K10
(Springer, 2022-07-09)
This work investigated the thermal characteristics of irradiated composite materials formulated on the urea–formaldehyde resin (UF) and differently activated montmorillonite (K10). UF resin with molar ratio F:U = 0.8 was ...
