Two outbreaks of herpes simplex virus type 1 (HSV-1) infection occurred in three newborns at each of two hospitals, and two of the infants in each case died of disseminated HSV-1 infection. Restriction endonuclease profiles of HSV-1 DNAs isolated from the three in each instance were essentially identical, indicating that they were epidemiologically related. In the first instance, each of three ...

Present-day and projected future changes in mean radiant temperature, T mrt in one northern, one mid-, and one southern European city (represented by Gothenburg, Frankfurt, and Porto), are presented, and the concept of hot spots is adopted. Air temperature, T a , increased in all cities by 2100, but changes in solar radiation due to changes in cloudiness counterbalanced or exacerbated the effec...

CIE, Commission Internationale de l’Eclairage – The CIE is an independent, nonprofit organization responsible for the international coordination of lighting-related technical standards, including colorimetry standards. Color-matching functions – Functions of wavelength l that describe the amounts of three fixed primary lights which, when mixed, match a monochromatic light of wavelength l of con...

Exposure of albino rats to incandescent radiant energy for a short period of time in an elevated environmental temperature (39 degrees C) causes degenerative changes in the extraocular muscles. The muscle fibres regenerate and the muscles reorganize if the animals are returned to room lighting and temperature. Extraocular muscles (EOMs) were damaged first near their insertion on the eyeball. Al...

Available output in the Scanning Laser Ophthalmoscope (SLO) may be expressed as radiant power at the beam pivot (SLO exit pupil), in units of microwatts (microW). This power corresponds to dimensions of brightness (like luminance and retinal illuminance) and to a range of related measures (like cd/m2, lm/m2, and the troland value) in both free and Maxwellian views. We demonstrate that the conve...

HIFU power measurement At ultrasonic laboratory of INRIM (Istituto Nazionale di Ricerca Metrologica) it is possible to measure the ultrasonic power emitted by HIFU (High Intesity Focused Ultrasound) transducers. Two different measuring systems for the determination of ultrasonic power have been developed. Both systems are based on the radiation force balance method. The first system is based on...

The quality of the image plays a vital role in image processing technique. It can be determined by the removal of the noisy pixels in the images. In this paper, we designed the hypergraph model for the representation of images. We use noise removal algorithm for digital images.This algorithm is based on the hypergraph model of images. This is used to detect the noisy pixels and thus can be remo...
