Molecular motors are found throughout the cells of the human body and have many different and important roles. These micromachines move along filament tracks and have the ability to convert chemical energy into mechanical work that powers cellular motility. Different types of motors are characterized by different duty ratios, which is the fraction of time that a motor is attached to its filamen...

The paper covers state of the art and latest development of piezoelectric motors at Kaunas University of Technology (Lithuania), that are related to the R&D of laser scanning and deflecting devices, measuring systems, nano-resolution positioning devices on the plane, various applications including teaching aids for Mechatronics studies and even “intelligent” toys. All presented motors are oneor...

Abstract Groundwater is one of the most important water sources in arid and semi-arid areas. With increasing world population demand for agriculture urban use, need resources has increased, especially regions, where groundwater play a significant role. To prevent pollution resources, various studies their preservation maintenance should be carried out, including detailed plan proper management ...
