Controlled and scalable torsional actuation of twisted nylon 6 fiber

Nylon-fiber-induced neutrophil fragmentation.

We have investigated the effects of mechanical elution of neutrophils from nylon-wool fiber (NWF) using the scanning electron microscope and biochemical analysis of elution fractions. We have determined that mechanical removal of neutrophils from nylon-wool fiber disrupts neutrophils adherent to nylon-wool fiber and augments release of granules, release of peripheral cytoplasmic fragments, and ...

Modification of Nylon 6 , 6 1

Nylon 6, 6 is regarded as tough and ductile materials since it exhibit high tensile elongation to break and high drop weight impact strengths. However, under conditions of stress concentration such as in the presence of sharp notches or cracks, polyamides exhibit brittle failure. This property, evaluated as notched Izod or Charpy impact tests, indicates that unmodified polyamides exhibit relati...

Nylon Fiber Leukapheresis : Associated Complement

The possible role of complement activation in the development of transient granulocytopenia during nylon fiber filtration leukapheresis ( FL) was studied in five normal donors. No changes in hemolytic complement (CH50) titers were observed in the donors’ circulating plasma at any point in the procedure. However, comparison of preand postfilter blood samples drawn 1 mm after donor blood passed t...

On Prismatic and Torsional Actuation for Running Legged Robots

Among the challenges faced when developing dynamic, legged platforms are the manner and mechanisms utilized to modulate system energy. A great deal of success has been demonstrated by low degree of freedom platforms that rely on either pure torsion or thrusting to provide the requisite locomotive power. However, means of synergizing these approaches and the potential benefits thereof are not we...
