We are used to bubbles rising in liquids, however, when a column of liquid is oscillated vertically, it is not always the case. Experiments have been conducted to determine the critical conditions under which such a behavior occurs. In a second part of this paper, it is shown, that the experimental results are in good agreement with an equation of...

Biomechanics of the masticatory muscles in correlation with teeth have been researched. Specific measurement models and special measurement methods have been used to simplify the complexity of the human chewing process. Here the function of the masseter muscle and the lateral pterygoid muscle as the key muscles in human masticatory system has been evaluated. A three-dimensional scan of a realistic...

I made a model that is capable of one drop and in a few seconds to determine the quality of gasoline. The device measures and displays the obtained data of two main parameters - the octane number from 80 to 100 and the specific active electrical conductivity of gasoline. To increase the accuracy of the readings, a scheme has been...

We present the fitting results of C2H spectra from selected regions of L1688 and L1689 from the Ophiuchus molecular cloud, finding complex structures in the southern part of L1689 and velocity ingredient in the northern part of L1689. Gildas/class was used to fit the spectra lines. The result shows that the northern part of L1689 is a single molecular cloud...
