Gravity as Archimedes' thrust and a bifurcation in that theory [PDF]
Found. Phys. Vol. 34, No 11, pp. 1703 - 1724 (2004), 2004 Euler's interpretation of Newton's gravity (NG) as Archimedes' thrust in a fluid ether is presented in some detail. Then a semi-heuristic mechanism for gravity, close to Euler's, is recalled and compared with the latter.

Generalization Of Lorentz-Poincare Ether Theory To Quantum Gravity [PDF]
arXiv, 1997 We present a quantum theory of gravity which is in agreement with observation in the relativistic domain. The theory is not relativistic, but a Galilean invariant generalization of Lorentz-Poincare ether theory to quantum gravity.

One-step Selective Synthesis of 13-epi-manoyl Oxide
Chemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2021 The selective one-step synthesis of 13-epi-manoyl oxide is reported based on a low-temperature superacidic cyclization of sclareol. The reaction conditions have been finely tuned in order to achieve a 9:1 ratio between epimeric oxides in favor of the ...

Mechanical properties and chemical stability of pivalolactone-based poly(ether ester)s [PDF]
, 1994 The processing, mechanical and chemical properties of poly(ether ester)s, prepared from pivalolactone (PVL), 1,4-butanediol (4G) and dimethyl terephthalate (DMT), were studied. The poly(ether ester)s could easily be processed by injection moulding, owing

Crystal structure of ethyl 4-[(4-methylbenzyl)oxy]benzoate
Acta Crystallographica Section E: Crystallographic Communications, 2022 The title compound, C17H18O3, crystallizes with three molecules in the asymmetric unit. The molecules differ in the conformation related to the ethoxy group and in the orientation of the two phenyl rings, one of which has the ethoxy group disordered over
