In this paper we study the initial value problem of fully nonlinear third-order equations on torus, that is ∂tu=F∂x3u,∂x2u,∂xu,u,x,t with F a smooth function depending space variable x, time t, first three derivatives u respect to and u. particular find conditions u(0) for which one can construct local unique solution if satisfy some then equation behaves like diffusive it has parabolic smoothi...

a 25 year-old construction worker underwent neck laceration following penetrating neck trauma in a falling incident. the 3rd tracheal ring was injured which was initially repaired and the patient was discharged in good general condition. (figure 1 shows the patient’s neck view after discharge from hospital).two months later the patient was again admitted due to provocative coughing and a metal ...

purpose: to compare clinical outcomes of two methods of corneal transplantation, penetrating keratoplasty (pk) versus lamellar keratoplasty (lk), in patients with delayed-onset mustard gas keratitis (mgk). methods: in this retrospective, comparative, interventional case series, 78 eyes of 55 victims of chemical warfare with delayed-onset mustard gas keratopathy who underwent pk or lk were enrol...

purpose: to report a case of bilateral kertatoconus who presented with acute comitant esotropia after penetrating keratoplasty in the fellow eye. patient and findings: a 17-year-old male with keratoconus underwent penetrating keratoplasty in his right eye. he experienced diplopia after removal of the patch from the operated eye 12 hour postoperatively due to esotropia in his left (unoperated) e...

Penetrating injuries to the orbit represent a small but very complicated portion of head injuries. Because of the close proximity to many vital structures, any penetrating orbital injury requires a multidisciplinary follow-up. Cases of penetrating injuries have flooded the literature, but no one has presented a systematic approach to the complications associated with these types of injuries. He...
