It was originally available in two versions, one in an 8-hour version, which was to follow Nickelodeon on RCA Satcom III-R, the other was a full 20-hour version, on another satellite provider, the Westar V. [4] In 1984, the signal split off from Nickelodeon, once A&E picked up its 20-hour signal on RCA Satcom III-R. [5] In response, Nickelodeon ...
Within the eye, 11-cis-retinal is bound to the protein opsin to form rhodopsin in rod cells and iodopsin in cone cells. As light enters the eye, the 11-cis-retinal is isomerized to the all-trans form. The all-trans-retinal dissociates from the opsin in a series of steps called photo-bleaching. This isomerization induces a nervous signal along ...
Vitamin E is a group of eight fat soluble compounds that include four tocopherols and four tocotrienols. [1][2] Vitamin E functions as a fat-soluble antioxidant which may help protect cell membranes from reactive oxygen species. [2][3] Symptomatic vitamin E deficiency, which is rare and is usually caused by an underlying problem with digesting ...

[ 197 ] The remaining 30% is ground water , 1% surface water (covering only 2.8% of Earth's land) [ 198 ] and other small forms of fresh water deposits such as permafrost , water ...
7.5% (July 1958) −3.7% Monetary policy was tightened during the two years preceding 1957, followed by an easing of policy at the end of 1957. The budget balance resulted in a change in budget surplus of 0.8% of GDP in 1957 to a budget deficit of 0.6% of GDP in 1958, and then to 2.6% of GDP in 1959. [40] Recession of 1960–1961: April 1960 –

Africa is the least generator of e-waste per capita at 2.5 kg. Regarding the collection and recycling of these waste, the continent of Europe ranked first (42.5%), and Asia came second (11.7%).
Here, Einstein used V to represent the speed of light in vacuum and L to represent the energy lost by a body in the form of radiation. [5] Consequently, the equation E = mc 2 was not originally written as a formula but as a sentence in German saying that "if a body gives off the energy L in the form of radiation, its mass diminishes by L ...
