A well-meaning half-Demon (or Cambion) whose true name is Anung Un Rama ("and upon his brow is set a crown of flame"), Hellboy was summoned from Hell to Earth as a baby by Nazi occultists (spawning his hatred for the Third Reich). He was discovered on a fictional Outer Hebrides Island by the Allied Forces; amongst them, Professor Trevor Bruttenholm, who formed the United States Bureau for Paranormal Research and Defense (B.P.R.D.). In time, Hellboy grew to be a large, red-skinned adult with a tail, horns (which he files off, leaving behind circular stumps on his forehead), cloven hooves for feet, and an oversized right hand made of stone (the "Right Hand of Doom"). He has been described as smelling of dry-roasted peanuts.
Hellboy works for the B.P.R.D., an international non-governmental agency, and for himself against dark forces including Nazis and witches, in a series of tales that have their roots in folklore, pulp magazines, vintage adventure, Lovecraftian horror and horror fiction. In earlier stories, he is identified as the "World's Greatest Paranormal Investigator".
In 2011, Hellboy was ranked 25th of the Top 100 Comic Book Heroes by IGN.
Litoria humboldtorum
Litoria humboldtorum is a frog from Indonesia. It lives near the Foya Mountains. Scientists saw it between 500 and 1050 meters above sea level.
Tridevi
Tridevi refers to three supreme goddesses , wifes of tridev - Lakshmi ( wife of Visnhu ) , Saraswati ( wife of Brahma ), Parvati/ kali ( wife of Shiva ).
Ethanol fermentation
Ethanol fermentation is a fermentation process that converts sugar into cellular energy, producing ethanol, and carbon dioxide. Because ethanol is an alcohol, it is also known as alcoholic fermentation. Yeast will do this without using oxygen, the process is anaerobic. It also happens in some kind of fish, where it produces energy, when there is little oxygen.
Ethanol fermentation has many uses, including the production of alcoholic drinks (such as beer or wine), the production of ethanol fuel, and the cooking of bread.
Flames of Passion
Flames of Passion is a 1922 British drama movie directed by Graham Cutts and starring Mae Marsh, C. Aubrey Smith, Hilda Bayley, Herbert Langley, Allan Aynesworth, Eva Moore, George K. Arthur. It is a lost movie.
Hyperbolic functions
In mathematics, hyperbolic functions are analogues of the ordinary trigonometric functions, but defined for the unit hyperbola rather than on the unit circle: just as the points form a circle with a unit radius, the points form the right half of the hyperbola.
Hyperbolic functions occur in the calculations of angles and distances in hyperbolic geometry. They also occur in the solutions of many linear differential equations, cubic equations, and Laplace's equation in Cartesian coordinates. Laplace's equations are important in many areas of physics.
The basic hyperbolic functions are:
from which are derived:
corresponding to the derived trigonometric functions.
The inverse hyperbolic functions are:
The hyperbolic functions take a real argument called a hyperbolic angle. The size of a hyperbolic angle is twice the area of its hyperbolic sector. The hyperbolic functions may be defined in terms of the legs of a right triangle covering this sector.
Hyperbolic functions were introduced in the 1760s independently by Vincenzo Riccati and Johann Heinrich Lambert.
There are various equivalent ways to define the hyperbolic functions.
In terms of the exponential function:
The hyperbolic functions satisfy many identities, all of them similar in form to the trigonometric identities.
Odd and even functions:
Hence:
Thus, and are even functions; the others are odd functions.
Hyperbolic sine and cosine satisfy:
the last of which is similar to the Pythagorean trigonometric identity.
One also has
for the other functions.
The hyperbolic functions represent an expansion of trigonometry beyond the functions defined on unit circle. Both types depend on one argument, either circular angle or hyperbolic angle.
Since the area of a circular sector with radius "r" and angle "u" (in radians) is "r""u"/2, it will be equal to "u" when "r" = . In the diagram, such a circle is tangent to the hyperbola "xy" = 1 at (1,1). The yellow sector depicts an area and angle magnitude. Similarly, the yellow and red sectors together depict an area and hyperbolic angle magnitude.
The legs of the two right triangles with hypotenuse on the ray defining the angles are of length times the circular and hyperbolic functions.
The decomposition of the exponential function in its even and odd parts gives the identities
and
The first one is analogous to Euler's formula

RGB color model
RGB (red, green, blue) is an additive color model. In this model red, green and blue colors are added together to form a new color.
An RGB color can be made by shining three colored lights of red, green, and blue onto a white wall in a dark room. Each light has a dimmer (to regulate its intensity.)
If only the red light is on, the wall will be red. If only the green light is on, the wall will look green. If the red and green lights are on together, the wall will look yellow. Dim the red light and the wall will become more of a yellow-green.
Each setting of the three dimmers will produce a different result, either in color or in brightness or both. The set of all possible results is the gamut. Swap the red lamp for one of a different brand that is slightly more orange, and there will be a slightly different gamut, since the set of all colors that can be produced with the three lights will be changed.
The name of the model comes from the initials of the three primary colors, red, green, and blue.
The purpose of the RGB color model is for capturing, storing, and displaying images in digital electronic devices, such as photo cameras, television sets, video cameras and computers. Before the electronic age, the RGB color model already had a solid theory behind it, based in human perception of colors.
The RGB color model is an additive color model in which red, green, and blue light are added together in various ways to reproduce a broad set of colors. The three light beams are added together, and their light spectra add to make the final color's spectrum. Zero intensity for each component gives the darkest color (no light, considered the "black"), and full intensity of each gives a white.
This is in stark contrast to physical paints, such as oil paint, which create black when mixed.
The additive color model is opposite to the subtractive color model, particularly the CMY color model.
The RGB color model is based on the Young–Helmholtz theory of trichromatic color vision, developed by Thomas Young and Hermann von Helmholtz in the early to mid-nineteenth century, and on James Clerk Maxwell's color triangle that elaborated that theory (circa 1860).
The first experiments with RGB in early color photography were made in 1861 by Maxwell himself, and involved the process of combining three color-filtered separate picture takes. To reproduce the color photograph, three matching projections over a screen in a dark room were necessary.
The modern RGB technology for color CRT displays was patented by Werner Flechsig in Germany in 1938.
A color in the RGB color model is recorded by indicating how much of each of the red, green, and blue is included. The color is expressed as an RGB triplet ("r","g","b"), each component of which can vary from zero to a defined maximum value. If all the components are at zero the result is black; if all are at maximum, the result is the brightest representable white.
These ranges may be quantified in several different ways:
For example, brightest saturated red is written in the different RGB notations as:
