background: usual dosage  of morphine  (10 mg/kg) induces  analgesia  and ultra-low dose (uld) of morphine (1 μg/kg); hyperalgesia, and  c-fibers are also bearing  μ- opioid receptors; here the importance  of c-fibers on pain and  morphine   induced  analgesia/hyperalgesia  is questioned   and  investigated    using   pain   evaluation methods and infant capsaicin treating  for c-fibers lesioni...

waveguides with low confinement loss, low chromatic dispersion, and low nonlinear effects are used in optical communication systems. optical fibers can also be employed in such systems. besides optical fibers, photonic crystal fibers are also highly suitable transmission media for optical communication systems. in this paper, we introduce two new designs of index-guiding photonic crystal fiber ...

determination of 1, 1-dimethylhydrazine (dmh) in air is carried out by spectrophotometry, gc or hplc analysis, but in this study dmh was analyzed by a gas sensor based on nanostructure conducting polyaniline. determination of dmh has been done very simplely and quickly in recent work. electrically conductive fibers have been prepared by polymerization of aniline on surfaces of commercial polyme...

: a new fibrous adsorbent was prepared by grafting acrylic acid /acryl amide (aa/aam) co-monomers onto poly(ethylene terephtalat) (pet) fibers. the resulting sorbent has been characterized by fourier transform infrared spectroscopy (ft-ir), thermo gravimetric analysis (tga), scanning electron microscopy (sem) and elemental analysis and studied for the preconcentration and determination of trace...

the increased surface area-to-volume ratio of nanoparticles, quantum size effects and the ability to tune surface properties through molecular modification make nanostructures ideal for environmental remediation. the present piece of work reports the preparation and characterization of nano cellulosic fibers (ncfs) with further polymeric reinforcement using vinyl sulphonic acid for the remediat...

the total coal and lignite consumption of the thermic power plants in turkey is approximately 55 million tons and nearly 15 million tons of fly ash is produced. the remarkable increase in the production of fly ash and its disposal in an environmentally friendly manner is increasingly becoming a matter of global concern. studies for the utilization of fly ash in turkey are necessary to reduce en...
