This case report is a 65 year old woman from Kerman. Her main complian is nasal obstruction and recurrent nasal bleeding from five months ago. In clinical examination there was a large tumor in left nasal cavity. CT scaning revealed a large tumor in left nasal cavity and maxillary sinuse. The tumor is resected compeletely with negative safe margine by radical caldwell- luc approach. The origin ...
Studying confined quantum systems (CQS) is very important in nano technology. One of the basic CQS is a hydrogen atom confined in spherical cavity. In this article, eigenenergies and eigenfunctions of hydrogen atom in spherical cavity are calculated, using linear variational method. B-splines are used as basis functions, which can easily construct the trial wave functions with appropriate bound...
In this paper, by considering a system consisting of a single two-level trapped ion interacting with a single-mode quantized radiation field inside a lossless cavity, the temporal evolution of the ionic and the cavity-field quantum statistical properties including photon-counting statistics, quantum fluctuations of the field quadratures and quantum fluctuations of the ionic dipole variables are...
A driven optical cavity containing a nonlinear medium can support stable, soliton-like objects, bright non-diffracting spots of light on a uniform background. Importantly, the nonlinear medium need not support ordinary (propagating) spatial solitons, and cavity solitons have been both predicted and observed in a saturable absorber, and predicted to even exist in self-defocusing media. The histo...
introduction: this study was designed to evaluate the usefulness of mastoid cavity obliteration with combined bone pâté and palva flap in the prevention of problematic mastoid cavities after canal wall down mastoidectomy. materials and methods: in a prospective longitudinal study with a mean follow-up of 28 months conducted between 2008–2012, a series of 56 ears in 48 patients with chronic ot...
an assessment of sonohysterography as a diagnostic tool for uterine cavity defects and tubal patency
introduction: in a prospective blind study, we evaluated sonohysterography (shg) as a diagnostic tool for uterine cavity and tubal patency and compare shg with laparoscopy in tubal patency and hysterosalpyngography for uterine anomaly as gold standard methods. material and methods: 76 infertile patients undergone shg and hsg and laparoscopy and comparison between the different diagnostic techni...
