Gold Fish - Lionhead (Oranda)

The Oranda, or so-called Dutch Lionhea, is one of the largest forms of this variey. It reaches a length of 30 cm, with the length of the tail equalling that of the head and body combined. All the fins are long. The Dutch Lionhead was apparently brought from China to Japan (Nagasaki) by Dutch merchants in the 17th century and bred further in that country

Mango

Several hundred acres of mango are grown commercially in Hawaii in addition to numerous dooryard plantings (Yee 1958). Singh (1960) reported that mangos cover about 7,000 acres in Florida but D. O. Wolfenbarger (personal commun., 1970) estimated that there were only about 2,000 acres.

Mango is grown for the egg-shaped, 2- to 6-inch long, greenish or yellowish to reddish fruit, which has a skin slightly thicker than that of a peach. The juicy, sweet to acid flesh around the hard mono- or polyembryonic stone is a popular fruit for millions of people in the tropical and subtropical areas around the world.

Solar Spectrum

The total distribution of electromagnetic radiation emanating from the sun. The different regions of the solar spectrum are described by their wavelength range. The visible region extends from about 390 to 780 nanometers (a nanometer is one billionth of one meter). About 99 percent of solar radiation is contained in a wavelength region from 300 nm (ultraviolet) to 3,000 nm (near-infrared). The combined radiation in the wavelength region from 280 nm to 4,000 nm is called the broadband, or total, solar radiation.
