objective 1-3% of the population suffer from epilepsy. up to 30% of them develop refractory epilepsy and their seizures occur more than once per month despite receiving at least 2 first line antiepileptic drugs. in  this group, more efficacious antiepileptics are needed. this study was undertaken to evaluate the efficacy and safety of oxcarbazepine as an adjunction therapy in children with refr...

purpose : to determine add power (ap) and amplitude of accommodation (aa) in a sample of iranian population and its relationship with refractive errors methods : this cross-sectional study enrolled people of 35-70 years old by simple random sampling. exclusion criteria were myopia or hyperopia over 6 diopter (d) and astigmatism more than 0.75 d. those with a history of eye disorders and taking ...

in this paper, using annular resonator we have designed an adding and dropping filter light based ontwo-dimensional photonic crystals. the shape of ring resonator filter adding and dropping that wehave proposed is race track. this filter has a hexagonal lattice structure of silicon bars withrefractive index 3/46 that is located in the context of air with refractive index 1. transmissionefficien...
