Cellulose nanofibril (CNF) films were prepared from side streams generated by the sugarcane industry, that is, bagasse. Two fractionation processes were utilized for comparison purposes: (1) soda and (2) hot water and soda pretreatments. 2,2,6,6‐Tetramethylpiperidinyl‐1‐oxyl‐mediated oxidation was applied ...

High demands on the economy of the power grids operation press the operators of electrical machinery and equipment to invest effectively to the management of the machines operation, maintenance, and renewal. At present, a number of concepts of management of important electrical machines...

In many applications, where rotating machines of high power are used, high demands on reliability and safety are laid. Precise manufacturing procedures has to be kept even in case of machines retrofits when e.g. rotors are newly assembled. Even small inaccuracies or misguiding the&...

Soft robotic grippers based on magnetorheological elastomers are proposed. Rigid nonmagnetic skeleton of the gripper is encased by an elastomer with magnetic properties that exhibits soft-touch properties and reacts to external magnetic field. The basic concept of the grippers, their operation&#x...

The current Czech is socially stratified and regionally differentiated, although there are also the processes of the opposite character in it, the unification and equalization. Language development includes in itself the antinomies opposing each other, but mutually complementary and converting in...
