With the increasing needs in the alternative fuels scientists offer new sources to obtain biodiesel. To evaluate potential of tyfon, oilseed radish and camelina (false flax) forms and varieties of Ukrainian breeding their seed oil content, fatty acid composition and oil yield were determined. Basing on fatty acid composition camelina form FEORZhYaFD was chosen as best biodiesel source, which exceed …
Universal platform with voice control
Easy-to-manage universal platform is required to develop robots for everyday housework, for using by disability persons, etc. To create such platform prototype was the project’s goal. Special (distribution) gearbox is installed and put into practice in the platform prototype in order to use motors that move driving wheels to perform other (additional) functions. The system of gears provides transmission both …
The effects of mass transfer and presence of the third components in the close stellar systems
We studied 9 close binary stellar systems in which one component eclipses another moving along its orbit. We found the increase or decrease of the period between eclipses in 6 systems. These changes can be caused by mass transfer between components. We calculated the rates of the mass transfer. Also, we found periodic changes of the period for 6 systems …
