Further on, linear discrimination analysis demonstrated that indices derived from SPPA are more suitable for differentiation between chronic and gestational hypertension and PE than those from traditional PPA (area under the ROC curve 0.85 versus 0.69). Therefore this procedure could contribute to the ...
driving them away from the head of the comet.In returning to lower-energy states, these excited ions emit photons and form a luminous,bluish-colored tail extending out from the comet directly away from the Sun.Since both kinds of tails are produced by radiation streaming out from the Sun, ...
Three tails either follow or guide the nucleus and coma. The ion, or plasma, tail is made up of charged ions that consistently face away from the sun due to solar winds. Because of this, the ion tail leads the comet away from the sun or it follows it towards the sun. The tail can...
Comets are irregular balls of dusty ice - "dirty snowballs" - a few km across. They are largely inert except when they are heated as they pass near the sun and release gas and dust to form their tails. The object that struck Siberia in 1908 is thought to have been a comet. An ...
The bright streaks extending to the left of the comet's fragments are "tails" produced by the solar wind (the sun is to the right of this image). ADVERTISEMENT Sporadic Meteors There are two kinds of meteors – sporadic meteors and shower meteors. Sporadics originate from random bits of ...
If you have a clear sky, watch a sunset in the west. However, what happens after that is interesting. Swivel 180 degrees to face east, and you'll see a dark blue band appear on the horizon with a deep pink color above. The blue band will rise as you watch it, and the pink will...
When the comet gets even closer to the Sun, one of its most spectacular parts begins to form the tail. Actually, there are two kinds of tails the dust tail and the ion tail. The dust tail is produced by the light from the Sun reflecting off the dust particles in the coma. A photon...
(nucleus), which can then be blasted away by the solar wind to form a tail, which is what we typically think about when we envision a comet. Because this is how the tails form, the tail will always point away from the sun and not simply trail behind it as it moves through space, ...

The percentage of DNA detected in comet tails, the tail moment and the olive tail moment are reported (B–D). Non-parametric one-way ANOVA was used for significance analysis. Non-significant conditions were grouped with the same letter; different letters represent significance between conditions. ...
