retinal detachment surgery has been considered an inpatient hospital procedure requiring preoperative and postoperative hospitalization. in this pilot study, outpatient retinal detachment surgery was performed on sixteen patients and the results (100% success rate after an average follow-up of 8.3 months) were comparable or better than reported overall success rates for retinal detachment in th...

Geologic observations of the Chinese Tian Shan foreland reveal active, contractional deformation along the entire margin. To quantify the amount of shortening and understand the structural style, we mapped the stratigraphy and structure of four folds expressed at the western end of the foreland, north of Kashi. In this region, upper Tertiary through Quaternary sediments are conformable, but an ...

The aim of this study was to determine the most suitable shaking frequency and amplitude for shake harvesting Esfahan's edible fig (Ficus carica cv. Sabz). A hand held limb shaker with adjustable shaking frequency and amplitude was used for this study. A 3x3 factorial experiment with three levels of oscillating frequency (10, 12 and 14 Hz) and three levels of shaking amplitude (20, 32.5 and 45 ...

[1] We analyze the kinematics of fault tip folding at the front of a fold-and-thrust wedge using a sandbox experiment. The analog model consists of sand layers intercalated with low-friction glass bead layers, deposited in a glass-sided experimental device and with a total thickness h = 4.8 cm. A computerized mobile backstop induces progressive horizontal shortening of the sand layers and there...

purpose: to evaluate the anatomical and functional outcomes of surgical management of retinal detachments associated with choroidal colobomas methods: in this retrospective study, 31 eyes of 31 patients with coloboma-related retinal detachments enrolled. all the eyes underwent standard three-port pars plana vitrectomy with internal tamponade with nonheavy silicon oil in 24 (77.4%) or 20% sulfur...

purpose: to compare the anatomical results of scleral buckling surgery with and without retinopexy in the management of phakic rhegmatogenous retinal detachment (rd). methods: in this retrospective, nonrandomized, interventional, comparative case series, data of 71 phakic eyes of 71 patients with rhegmatogenous rd that had undergone scleral buckling were evaluated. the procedure in 41 consecuti...

the purpose of this study was to compare the anatomic and visual outcome of primary vitrectomy with scleral buckling in patients with retinal detachment following cataract surgery. fifty-six consecutive patients with retinal detachment after cataract surgery were randomly assigned to two treatment groups: standard scleral buckling and standard three-port deep vitrectomy. successful treatment wa...

in this work, different types of chaotic 1-manifolds which lie on the chaotic spheres or on a torus are introduced. some types of retractions of the chaotic spheres affect on the 1-chaotic systems, and other types of retractions occur to the geometric manifold but make the 1-chaotic manifold invariant. the existed retractions are discussed through new proved theorems. also we construct diffe...
