The restricted three body problem was outlined. acceleration due to planetary magnetic field, in terms of space craft’s orbital elements, analysed. conditions for calculating the liberation points including mutual gravitational attraction and effect Lorentz were derived case circular planer bodies. stability solution artificial triangular studied. Finally, numerical investigation Sun-Jupiter sy...

The aim of this research was to investigate the physico-mechanical, thermal, and morphological properties cement-bonded wood particleboards produced by using fly as has a partial cement replacement spruce planer shavings. Experimental single-layer target density 1200 kg/m3, 1/3 wood-cement ratio, dimension 460x460x10 mm3 5%, 10%, 15%, 20% ash were tested for physical mechanical in accordance wi...
