objectives : this study sought to assess the effect of low-level laser (lll) on pain and trismus after impacted mandibular third molar surgery. materials and methods : this double blind controlled clinical trial was conducted on 40 healthy patients with no underlying disease and impacted mesioangular mandibular third molars with the same level of difficulty. the patients were divided into two g...

purpose: to evaluate the complications of scleral perforation during strabismus surgery and the role of cryopexy, laser therapy, and conservative management in an animal model. methods: in this experimental study, 42 pigmented-eye rabbits were included. an s-24 needle attached to a 6-0 polyglactin suture was passed through the sclera and into the vitreous cavity in both eyes of the animals. one...

purpose: retinopathy of prematurity (rop) adversely affects normal ocular vascularization in premature infants. it can be mild with no visual consequences, or may become aggressive with new vessel formation and even progress to retinal detachment and blindness. modern treatment can prevent blindness due to neovascularization but uncorrected refractive errors may lead to amblyopia. methods: in t...

introduction: endovenous laser therapy (evlt) for greater saphenous vein (gsv) insufficiency is a newly established method of treatment only recently made availablein iran. the present study seeks to describe the results of the first 20 patients treated with evlt at shohada-e tajrish medical center, tehran, iran. methods: 20 patients (16 male, 4 female) with the mean age of 38.9 and an average ...

We consider low cost discrete bit loading based on greedy power allocation (GPA) under the constraints of total transmit power budget, target BER, and maximum permissible QAM modulation order. Compared to the standard GPA, which is optimal in terms of maximising the data throughput, three suboptimal schemes are proposed, which perform GPA on subsets of subchannels only. These subsets are create...

This paper reports the results of a pre-post outcomes study on the impact of tilt-in-space power wheelchairs on the health, activity, and participation of 5 subjects. Using a methodology which combines traditional self-reports and activity monitoring technology, subjects who had previously used an upright power wheelchair were monitored at baseline and 3 months following receipt of a new tilt-i...

In order to minimize the quantity of active materials that require long-term storage, arising during operation and after fusion power plant decommissioning, maximum use should be made of both recycling within the nuclear industry and clearance. For the latter, revised limits have recently been issued at the international level and in the U.S. and Europe. In this paper the implications for fusio...
