atechnical feasibility study has been conducted on production of nano- and micro-fibrils from nylon 6/polypropylene grafted with maleic anhydride/polypropylene blended films. fibrils are prepared in four consecutive steps.in the first step the polymers melt blended in an extruder with and without compatibilizers to produce chips; in the second step films are extruded from polymer blends chips, ...

The aim of this study is to enhance the tensile and flexural strength polyamide (nylon 6, 6) by incorporation glass fibre. Nylon has high elasticity, strength, toughness maintain mechanical properties at elevated temperatures. method employed for enhancement reinforcement Glass fibre most extensively used material. It a lightweight, extremely solid, durable, low cost material that moderafly sti...

INTRODUCTION Single-port laparoscopic surgery has some technical limitations with respect to control of the forceps inserted through the single-access site, which results in increased internal collisions due to coaxial alignment of the instruments, as well as and decreased range of motion and visualization. To overcome these limitations, we employ a "modified marionette technique" as a way to c...

Nylon denture base material could be a useful alternative to poly (methyl methacrylate) (PMMA) in special circumstances such as patient allergy to the monomer. The aim of this study was to evaluate the flexural properties of a nylon denture base material (Lucitone FRS), a conventional compression-moulded heat-polymerized (Meliodent), a compression-moulded microwave-polymerized (Acron MC) and an...

The toughening of an aromatic amine-cured diglycidyl ether of bisphenoI-A epoxy with particles of crystalline polymers was studied. The crystalline polymers were poly(butylene terephthalate), nylon 6, and poly(vinylidene fluoride). Nylon 6 and poly(vinylidene fluoride) were found to toughen the epoxy about as well as did an equivalent amount of CTBN rubber. Poly(butylene terephthalate) was foun...

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...
