OBJECTIVES Nylon sutures and skin staples are used commonly in total knee arthroplasty (TKA) surgical wound closure. However, there is no study that compares the wound healing efficacy and patient satisfaction scores of both techniques in the same knee. METHODS We randomised 70 patients who underwent primary TKA into two groups. In one group of 34 patients, the skin at the upper half of the w...

Borexino is a solar neutrino experiment designed to observe the 0.86MeV Be neutrinos emitted in the pp cycle of the sun. Neutrinos will be detected by their elastic scattering on electrons in 100 tons of liquid scintillator. The neutrino event rate in the scintillator is expected to be low (∼0.35 events per day per ton), and the signals will be at energies below 1.5MeV, where background from na...

Nylon filters are a popular medium to collect atmospheric fine particles in different aerosol monitoring networks, including those operated by the U.S. Environmental Protection Agency and the Interagency Monitoring of Protected Visual Environments (IMPROVE) program. Extraction of the filters by deionized water or by a basic aqueous solution (typically a mixture of sodium carbonate and sodium bi...

Polyaniline and polyamide (nylon 6,6) nanocomposites with Silva were prepared by in-situ oxidativepolymerization of aniline monomers in the presence of Ag salt Nano particles of silver (NPs) were symthesieedby controlled reduction of Ag+ ions kith sodium borohydride at room temperature. Nylon 6,6 wax loaded withAg nanoparfieles by erdrapment of Ag+ ions into the polymer network, followed by red...

A new family of β-lactams is described that enables anionic ring-opening polymerization (AROP) to prepare nylon-3 materials bearing diverse appended functionality, including carboxylic acid, thiol, hydroxyl and secondary amine groups. Nylon-3 copolymers generated with the new β-lactams are shown to display distinctive self-assembly behavior and biological properties.

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...
