Effectiveness of emergency argon laser retinopexy performed by trainee doctors

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Working time regulations for trainee doctors.

In the linked analysis article, Purcell Jackson and Ta rpley describe their concern that surgical trainees in the United States might be forced to work within a maximum 80 hour week.1 Meanwhile, the European Working Time Directive (EWTD) demands that all trainee doctors in Europe work an average of only 48 hours a week,2 and the Royal College of Surgeons of England is appealing for all their tr...

Treatment of diabetic maculopathy by argon-laser.

Tracheal rhinoscleroma treated by argon laser.

Rhinoscleroma is a chronic progressive granulomatous condition due to Klebsiella rhinoscleromatis.' In severe cases the typical nodular lesions may extend from the nasopharynx into the respiratory tract and be refractory to antibiotics. We are currently investigating the use of laser treatment for lesions in the trachea and major bronchi.2 Such treatment is applicable to benign and malignant le...

Tympanic membrane healing in myringotomies performed with argon laser or microknife: an experimental study in rats.

UNLABELLED Secretory otitis media (SOM) and recurrent acute otitis media (RAOM) may require surgical treatment to proper ventilate the middle ear. Incisional myringotomy is usually done under microscopy with a micro-knife, but it remains patent for just a few days. Recent research indicates that laser assisted myringotomies remain open much longer, allowing middle ear ventilation and healing. ...
