We investigate the Kerr and magneto-optical effects for a probe laser field with two orthogonally polarized components, propagating in cold Rydberg atomic gas an inverted-Y-type level configuration via double electromagnetically induced transparency (EIT). Through approach beyond both mean-field ground-state approximations, we make detailed calculations on third-order nonlinear optical suscepti...

in our country, student transportations’ security and driving accidents statistics for students is one of the major concerns for relevant organizations such as educational organization. in current year, a system, was named sepand, was formed in city taxi driver :::::::union::::::: by educational organization, naja traffic and city taxi driver :::::::union:::::::. in this systems’ plan, basis on...

objective and aims intrauterine devices (iuds) are placed in the uterine cavity with the objective of providing long-term contraception, mainly by preventing fertilization. in this research has been tried to show that method of iud insertion is effective to decrease complications’ incidence . rotating withdrawal technique is presenting, has been using for this purpose. design and setting this h...

background implant removal is a common procedure in orthopedic surgery which can be associated with many complications such as scar formation, hematoma, nerve injury, infection, and refracture. indications for orthopedic implant removal have declined in recent years. most studies have considered orthopedic hardware removal as an unnecessary procedure in the absence of severe complications such ...

craniospinal irradiation plus posterior fossa boost (cs1) is the standard modality of post-operative treatment of patient with medulloblastoma, but considering the technical difficulties and limited facilities, often whole- brain irradiation plus posterior fossa boost (wbi) had been used in our institution until 1991. tust a retrospective study was undertaken to compare the patients treated by ...

A series of iron garnet films of composition Lu Bi Fe Ga O grown on (100) oriented GGG substrates have been studied 3yx x 5yy y 12 using variable angle spectroscopic ellipsometry and polar Kerr spectroscopy (MOKE). The diagonal and off-diagonal components of the permittivity tensor have been determined in the range 1–5 eV. Our results seem to be in accordance with previously reported measuremen...
