Sentences with phrase «traction forces»

Chemical reactions of small biopolymer sub units or complex polymer chains under the influence of traction forces and catalytic nanoparticles could be investigated with this new method.

An implanted, programmable medical robot can gradually lengthen tubular organs by applying traction forces — stimulating tissue growth in stunted organs without interfering with organ function or causing apparent discomfort, report researchers at Boston Children's Hospital.

We show that TGFβ - induced EMT promotes dissemination of A549 cells in a 2 / 3D assay, independently of proteolysis, by activating the Rho / ROCK pathway which generates actomyosin - dependent contractility forces that actively remodel the extracellular matrix, as assessed by Traction Force microscopy.

Many different cell types including fibroblasts, smooth muscle cells, endothelial cells, and cancer cells exert traction forces on the fibrous components of the extracellular matrix.

Cells then move forwards by exerting traction forces on the adhesions at its front and by disassembling adhesions at the rear.

These growth centers are made of cartilage that is growing into bone, and are fragile and vulnerable to recurrent traction forces of overhead throwing.

The new study by the Inagaki lab showed that neurons will produce four times more traction force when placed on adhesive substrates coated with laminin than those without laminin, assuring the axons reach their final destination.

They used traction force microscopy to measure how the organism deformed the pattern of beads: the greater the deformation, the greater the force.

A programmable control unit outside the body applies adjustable traction forces to the rings, slowly and steadily pulling the tissue in the desired direction.

These safety functionalities can be enhanced by means of torque - vectoring through the electric motors... a yaw moment can be continuously generated without variation of the net traction force.

The E-Drive system uses the three motors to enhance cornering performance by torque vectoring and front / rear traction force allocation.

Indeed, uncoupling of the Exocyst subunit Sec5 from GEF - H1 impairs RhoA activation, generation of traction forces and cell dissemination.

This increased grip state strengthens the traction force produced by the axon onto the adhesive substrate, allowing the axon to turn and change its direction on cue.

A study in the Scandinavian Journal of Rehab Medicine showed that pressure inside the disc could be reduced to at or near zero by applying a traction force equal to about 60 % of your body weight — which is roughly equivalent to 60 degrees of inversion on a Teeter.

The traction force also results in a traction torque on the rear wheels which opposes the drive torque.

This results in a reactive friction force, known as the traction force, which is what pushed the car forward.

Kitted out with ECO4 energy efficiency gadgetry, such as Bombardier's MITRAC Permanent Magnet Motor and an assistance system which allows the driver to monitor speed and traction force, this new train not only set a new Swedish speed record (295 km / h; 183 mph) but consumes 20 - 30 % less energy than your average train.
