A novel and facile approach to prepare hybrid nanoparticle embedded polymer nanofibers using pressurised gyration is presented. Silver nanoparticles and nylon polymer were used in this work. The polymer solution's physical properties, rotating speed and the working pressure had a significant influence on the fibre diameter and the morphology. Fibres in the range of 60-500nm were spun using 10wt...

Methyl azelaaldehydate, soy nitriles, and oleonitrile were compared as starting materials for making nylon-9. Less difficulty was encountered in purifying intermediates from oleonitrile than from the other two. All 3 routes involved hydrolysis of methyl 9-aminononanoate to 9-aminononanoic acid. Self catalyzed hydrolysis of the amino ester in water produced low yields of monomer owing to oligome...

this study was carried out to determine the effects of gamma irradiation on dry matter (dm) and on crude protein (cp) degradation of rapeseed meal, using nylon bags and sds-page techniques. ruminal nylon bags of either untreated or irradiated rapeseed meal at doses of 25, 50 and 75 kgy were suspended in the rumen of four non-lactating holstein cows for up to 48 h. intestinal crude protein diges...

Polyamide 6 intercalated/exfoliated (PIE) cements are fabricated and characterized. With the reinforcing nanointerphase, the flexure strength of a PIE cement is higher than that of ordinary cements by an order of magnitude. The optimum nanointerphase content is around 10 wt.%. This technique has great potential in developing advanced precast and repair technologies. © 2005 Elsevier B.V. All rig...

The use of odor baits for surveillance and control of malaria mosquitoes requires robust dispensing tools. In this study, the residual activity of a synthetic mosquito attractant blend dispensed from nylon or low density polyethylene (LDPE) sachets was evaluated at weekly intervals for one year without re-impregnation. The potential role of bacteria in modulating the attraction of mosquitoes to...

Severe pulmonary reactions have been reported in patients receiving leukocyte transfusion and amphotericin-B. To study the interaction of amphotericin-B with polymorphonuclear leukocytes (PMN), purified human PMN were incubated with 200 mg of nylon wool fiber for 60 min either in the absence or presence of 2 mM EDTA. PMN were recovered in acid citrate dextrose solution and were suspended in bal...

Si yo tuviera que señalar a los filósofos del Derecho me han proporcionado lo más importante bagaje intelectual hoy pueda tener, entre la media docena citaría (Kelsen, Hart, Ross, von Wright, Raz) ocuparían un lugar muy destacado Carlos Nino, de lado, y Alchourrón Eugenio Bulygin, otro. Tanto Nino como Bulygin enseñado mucho influido mucho, pero, además, fue gracias al primero tuve las primeras...
