Pulmonary arterial flow was examined in 60 normal children with a mean age of 8.5 +/- 3.7 years (range 3.3 to 17.9 years) and mean body surface area of 0.95 +/- 0.3 m2 (range Pivot Tube 0.6 m2 to 1.7 m2) by pulsed Doppler echocardiography.Two distinct antegrade waveforms during diastole were detected.The peak velocities of early diastolic forward f
Natural products represent a valuable resource for discovery and development of anticancer drugs.About 80% of drugs approved by the United States Food and Drug Administration during the last three decades for cancer therapy are either natural products per se or are based on, or mimicked natural products.Various extracts, fractions, mixtures and pur
Mycoplasma anatis, M.anseris, M.cloacale and M.sp.1220 colonise geese and ducks, and could be associated with infections of avian respiratory and nervous systems, cause mild to severe inflammation of cloaca and genital tracts, and embryo lethality.Co-occurrence of these Mycoplasma species in waterfowl is frequently detected and the identification o
High resolution remote sensing systems provide cheaper and fast way of acquiring images of power lines.However, such images depicting the details of other complex background objects, noises, and complicated brightness measurements, make separate extraction of the power lines challenging.This paper addresses the problem of automatic extraction of po
