هدف: برای بررسی خصوصیات انواع چشم بندهای مورد استفاده برای فتوتراپی و یافتن مناسب ترین نوع چشم بند مطالعه ای توصیفی – تحلیلی در سال 1388 در بیمارستان های شهر کرج به عمل آمد. روش مطالعه: این مطالعه به صورت یک بررسی توصیفی – تحلیلی (descriptive-analytical) مقطعی (cross-sectional) در نیمه دوم سال 1388 در بیمارستان های شهر کرج به عمل آمد و انواع چشم بندهایی که در این بیمارستان ها مورد استفاده قرار...
The infrared night vision illuminates are a kind of flare that, with radiation in the near infrared range (700-900 nm) cause illuminates the target in the battlefield and night operations. These illuminates have problems such as low infrared radiation, low burning rate, and so on. Many physical and chemical parameters affect the burn rate and radiation intensity. But the most effective paramete...
the harmful effects of the long-term ocular exposure to cumulative levels of infrared radiation (ir) in glassblowing and foundries have been recognized since the late 19th century. these effects include cataracts, keratitis, and chronic dry eye problems. therefore, infrared radiation measurements are critical and need to be assessed regularly in the industries and workplaces where there are hig...
