The blends formed mixing hydrofluorocarbons (HFC) and hydrocarbons (HC) can be classified as semi-natural refrigerants since, by optimizing the composition, it is in principle possible to adapt basic features such as GWP, TEWI and flammability to the industrial and environmental requirements. However, the energetic efficiency must be competitive with the traditional refrigerants. To evaluate th...

A passive sensing node technology is introduced for monitoring the integrity of RF coaxial transmission lines and associated RF connectors in the UHF range of frequencies. Each passive sensing node is powered by a transmission line coupler inside the coaxial cable. Passive sensing node sensing elements, fineline interconnect metallurgy, transmission line coupler, and electronics are packaged on...

BACKGROUND: The reasons for the development of postoperative reactive inflammation under optimal conditions operation are errors in surgical technique and presence viscoelastic residues. likelihood developing ophthalmic hypertension exists with use any type. Its incomplete evacuation can be explained by difficult visualization due to its transparency. Analysis dependence period course on qualit...

To observe curative effects of phacoemulsification combined with intraocular lens implantation alone or associated with vitreous aspiration in treating angle closure glaucoma (ACG) patients with concomitant cataract. A retrospective comparative analysis of 72 ACG patients (78 eyes) with concomitant cataract was conducted. Patients in group A underwent phacoemulsification combined with intraocul...

PURPOSE To evaluate whether phacoemulsification after trabeculectomy affects postoperative intraocular pressure (IOP). SETTING Kumamoto University, Kumamoto, Japan. DESIGN Cohort study. METHODS The medical records of patients with primary open-angle glaucoma or exfoliation glaucoma who had trabeculectomy with mitomycin-C were reviewed. The primary endpoints were condition A (persistent po...

PURPOSE To provide an overview of intraoperative and postoperative complications during phacoemulsification cataract surgery and to evaluate the visual results in patients having pars plana vitrectomy (PPV) with 10 years of follow-up. METHODS Retrospective evaluation of intraoperative and postoperative complications and postoperative visual results in 134 consecutive patients who underwent ph...

Aims: To study the incidence, management, and outcomes of suprachoroidal haemorrhage (SCH) complicating cataract surgery in the United Kingdom. Methods: Cases were prospectively collected by active surveillance through the British Ophthalmological Surveillance Unit. Details were obtained using an incident questionnaire with follow up at 6 months. Results: 118 cases were reported in 1 year. The ...

BACKGROUND To establish whether a previously validated scoring system (Habib) for the prediction of risk or likelihood of posterior capsule rupture during phacoemulsification surgery could be used to: 1. Predict the difficulty of a phacoemulsification case, and 2. Select appropriate phacoemulsification cases for trainees. METHODS The study sample was consecutive phacoemulsification cases unde...

OBJECTIVE To compare the diagnostic rate, patient comfort, and complications of ultrasonography-guided breast biopsy using a modified coaxial technique with ultrasonography-guided fine needle aspiration and traditional core biopsy. A secondary objective was to describe the use of the coaxial technique for the biopsy of breast lesions and our initial experience. DESIGN Retrospective study. S...

purpose : to investigate tear film status after phacoemulsification surgery with temporal and supratemporal clear corneal incision in a cohort of patients with senile cataract methods : we enrolled sixty eight eyes of 68 patients with senile cataract requiring phacoemulsification in a prospective, cohort study. all patients undergone basic tear secretion test (btst), tear meniscus height (tmh),...
