Hand Sanitizer Alert
and irregular hyperplasia with a pseudoepitheliomatous area. A highly dense, nodular, diffuse inflammatory infiltrate was observed at all levels of the dermis. It consisted of macrophages and numerous multinucleated cells, most of them of the foreign body type. Fibroplasia was also noted. Abundant, round parasitic elements surrounded by a double membrane and containing a basophilic nucleus were...
متن کاملHand Gesture Recognition Using Ultrasonic Sensor and Atmega128 Microcontroller
The aim of this paper is to present a system that detects the hand gesture motions using the principle of Doppler Effect. Ultrasonic waves are transmitted by a sensor module and are reflected by a moving hand. The received waves are frequency shifted due to Doppler Effect. These frequency shifts in the ultrasonic waves are characterized to determine gestures. The gestures once recognized are ma...
متن کاملAutomatic Design of Persian Typefaces
In this paper
, a fast method for automatic generation and scientific design of Persian letters is proposed. Scientific typeface design is an approach in which fonts are described by mathematical curves with well-defined parameters, where these parameters can be automatically tuned. METAFONT is a language suitable for the type of design used in this work. This language is particularly useful...

متن کاملAlcohol-free instant hand sanitizer reduces elementary school illness absenteeism.
UNLABELLED BACKGROUND AND HYPOTHESES: A substantial percentage of school absenteeism among children is related to transmissible infection. Rates of transmission can be reduced by hand washing with soap and water, but such washing occurs infrequently. This study tested whether an alcohol-free instant hand sanitizer (CleanHands) could reduce illness absenteeism in school-age children. METHODS A...
