construction and validation of translation metacognitive strategy questionnaire and its application to translation quality
like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
Structure and Function of the Bi-Directional Bacterial Flagellar Motor
The bacterial flagellum is a locomotive organelle that propels the bacterial cell body in liquid environments. The flagellum is a supramolecular complex composed of about 30 different proteins and consists of at least three parts: a rotary motor, a universal joint, and a helical filament. The flagellar motor of Escherichia coli and Salmonella enterica is powered by an inward-directed electroche...
متن کاملBacterial flagellar motor
What do you think of the state of biology today? It has indeed changed in many ways, and to the good. Molecular biology has come into its own and provides enormous power to answer new and old questions in such areas as development, physiology, and cell biology. The use of mathematical tools has become increasingly effective in shedding light on ecological and evolutionary problems, and other ma...
متن کاملBacterial Flagella: Flagellar Motor
Many species of bacteria actively seek out favourable conditions for growth by swimming up gradients of nutrients, oxygen, light or other attractants, or down gradients away from toxic substances (repellants). Different species employ several different modes of swimming, almost all of which are driven by the rapid rotation of helical flagellar filaments that protrude from the cell. Rotation of ...
متن کاملBacterial flagellar motor.
The bacterial flagellar motor is a reversible rotary nano-machine, about 45 nm in diameter, embedded in the bacterial cell envelope. It is powered by the flux of H+ or Na+ ions across the cytoplasmic membrane driven by an electrochemical gradient, the proton-motive force or the sodium-motive force. Each motor rotates a helical filament at several hundreds of revolutions per second (hertz). In m...
