Maxillofacial defects compromise appearance and function making individuals incapable of leading a relatively normal life. It is always not possible to rehabilitate all these using plastic surgery. Although remarkable advancements have evolved in this field, the patient’s financial constraints make prosthodontist think about basic concepts techniques fabrication prostheses. Hence an acceptable ...

We investigate the electronic properties in Bloch electron on a square lattice with vacancies uniform magnetic field. show that single vacancy site introduced to system creates defect energy level every innumerable fractal gap Hofstadter butterfly. The wavefunctions of different levels have all localization lengths depending their generations, and they can be described by universal function aft...

BACKGROUND Blow-out fracture of the orbit is a common injury. However, not many cases are associated with massive subcutaneous emphysema. Even fewer cases are caused by minor trauma or are associated with barotrauma to the orbit due to sneezing, coughing, or vomiting. The authors present a case of blow-out fracture complicated by extensive subcutaneous and mediastinal emphysema that occurred wi...

.. Objective: To determine the outcome of orbital floor reconstruction with titanium mesh in terms of diplopia, enophthalmos, dystopia and infection etc. Study design: Descriptive case series. Place & duration of study: Department of Oral & Maxillofacial Surgery, Punjab Medical College / Allied Hospital Faisalabad. One and Half year from 01-10-12 to 31-03-14. Material and Method: Twenty two pat...

Abstract* Introduction: Visual system have been considered as among important sensory system in animals’ life span and their survival is closely related to normal visual system functioning. Since in previous studies it have been revealed that morphine consumption during pregnancy could lead to defect and delay in nervous system development in the embryos, in the present study, changes induc...

purpose : to report a rare case of large vascularized astrocytoma on optic disc. case report : a 12-year-old boy with history of decreased vision in the left eye since 5-6 months ago was referred to the ocular oncology service at rassoul akram hospital with provisional diagnosis of retinoblastoma. on examination, visual acuity was counting fingers at 50 cm, and a 3+ relative afferent pupillary ...

We present a critical theoretical study of electronic properties of silicon nanoclusters, in particular the roles played by symmetry, relaxation, and hydrogen passivation on the the stability, the gap states and the energy gap of the system using the order-N [O(N)] non-orthogonal tight-binding molecular dynamics and the local analysis of electronic structure. We find that for an unrelaxed clust...

We report that light beams, guided along liquid crystal defect lines, can be transformed into vector beams with various polarization profiles. Using finite-difference time-domain numerical solving of Maxwell equations, we confirm that the defect in the orientational order of the liquid crystal induces a defect in the light field with twice the winding number of the liquid crystal defect, coupli...
