A parabolic (or paraboloid or paraboloidal) reflector (or dish or mirror) is a reflective surface used to collect or project energy such as light, sound, or radio waves.

Before the light bulb was invented, people had figured out how to put a reflector behind it, focus it a little bit put lenses in front of it, focus it a little bit better.

So melanin was recruited, in our lineage, and specifically in our earliest ancestors evolving in Africa, to be a natural sunscreen.

Preliminary estimates (table 1) show that 25,234 tonnes CO2 equivalent were emitted by the tenth session of the Conference of the Parties (equivalent to about 4.1 tonnes CO2 equivalent participant).

This means that the energy consumption per capita is around 7.2 tons of oil equivalent per year.

Thus, additional hypotheses have to be introduced to infer an AVE from the estimated price gap.

In 1866, Auguste Mouchout used a parabolic trough to produce steam for the first solar steam engine.

1 GT (or gigatonne) CO2 equivalent means 1,000 million of tonnes of CO2.

For the latter two gases, it would result in an emission of 0.7 Gt CO2 eq in 2015 in the mitigation scenario, compared to an emission of 1.2 Gt CO2 eq in the business as usual scenario.

) Surrounded by a U 238 reflector tamper, the Fat Man's pit was brought close to critical mass by the neutron reflecting properties of the U 238.

The figure for the twentieth sessions of the subsidiary bodies was 2,900 tonnes CO2 equivalent.

Much later, Robert Maillart's bridges, which optimize structural form with a calculus curvature almost like a parabola.

The tawjihi is the general secondary examination in Gaza, the West Bank and Jordan, and it determines a student's choice of university and major.

A small part (145,141 ktoe, which was 3 of the input total) of the heat was utilized at co generation heat and power plants.

In 1876 a French engineer, A. Mangin, invented what has come to be called the Mangin mirror, a concave glass reflector with the silver surface on the rear side of the glass.

The narrow beam width of a normal parabolic satellite antenna means it can only receive signals from a single satellite at a time.

However, the complexity of the environment and the new tasks did not appear to result in a commensurate revision of UNMO's role and operational modalities.

This implies a decrease of 0.5 Gt CO2 eq by 2015, or as much as 40 per cent.

The Renewables 2004 conference generated about 3,500 tonnes of GHG (1.44 tonnes CO2 equivalent participant).

The 10 day WSSD meeting generated about 290,000 tonnes of CO2 (6.6 tonnes CO2 equivalent participant).

So if I put this inside this water here, you can see a silver reflective coating around it, and that silver reflective coating is the layer of air that's protecting the water from touching the paddle, and it's dry.

The ISAAC uses a parabolic trough solar collector and a compact and efficient design to produce ice with no fuel or electric input, and with no moving parts.

In particular 0.333... ...000... and 0.999... ...000... do not correspond to any number.

The AI people said, well, the thing in the box is a programmable computer because that's equivalent to a brain, and we'll feed it some inputs and we'll get it to do something, have some behavior.

So, very interesting parallels between the biological and the engineering worlds. And interestingly, this turns out the stomatopod saddle turns out to be the first described biological hyperbolic paraboloid spring.

Total energy consumed at all power plants for the generation of electricity was 4,398,768 ktoe (kilo ton of oil equivalent) which was 36 of the total for primary energy sources (TPES) of 2008.

The barrel of oil equivalent (BOE) is a unit of energy based on the approximate energy released by burning one barrel (42 U.S. gallons or 158.9873 litres) of crude oil.

Other methods of geoengineering that is, consciously manipulating the climate include painting the roofs of houses white in order to increase the reflection of sunlight, covering deserts with reflective plastic, and fertilizing the seas with iron in order to increase the absorption of CO2.

The amount supplied to the final consumer was 1,445,285 ktoe (16,430 TWh) which was 33 of the total energy consumed at power plants and heat and power co generation (CHP) plants.

The downlinked satellite signal, quite weak after traveling the great distance (see inverse square law), is collected with a parabolic receiving dish, which reflects the weak signal to the dish's focal point.

You can think of this nagging inner voice as sort of the brain's equivalent of the Catholic Church, if you're an Austrian like me, or the super ego, if you're Freudian, or your mother, if you're Jewish.

Two IEA climate policy scenarios show how we could stabilize the concentration of greenhouse gases at 550 or 450 parts per million of CO2 equivalent.

The stem needs not to be identical to the morphological root of the word it is usually sufficient that related words map to the same stem, even if this stem is not in itself a valid root.

According to the Gender Equality Act, the employer must not establish conditions for remuneration or other conditions which are less favourable regarding an employee of one sex compared to an employee of the other sex doing the same or equivalent work.

Concentrations of carbon dioxide and other greenhouse gases in the atmosphere have reached 435 parts per million (ppm) of CO2 equivalent, compared with about 280 ppm before industrialization in the nineteenth century.

There appears to be general agreement that this approach remains appropriate in relation to so called contracts of adhesion, i.e. contracts concluded on the carrier's standard terms as contained in or evidenced by a transport document (or electronic equivalent).

MT (or mega tonne) of CO2 equivalent means 1,000,000 tonnes of CO2. For purposes of comparison, a single 100 MW power plant could emit 0.4 0.6 Gt of CO2 annually.

Furthermore, during the past 10 years, only about two thirds of worldwide demand for nuclear fuel about 68,000 tons of natural uranium equivalent are needed for 2010 was met from resources obtained from mining. The remaining 20,000 tons came from so called secondary uranium sources mainly inventories held by utilities and governments, re processed nuclear fuel, and stockpiles of depleted uranium.

Indeed, the remaining carbon emissions budget until 2050, adherence to which is required to limit the global temperature increase to 2 C, is five times smaller than the carbon equivalent of proven fossil fuel reserves.

Globally, more than 30 million tons of oil equivalent are consumed in the form of primary energy every day, equivalent to 55 kilowatt hours per person per day, with rich countries, on average, consuming more than twice that figure.
