total-, tot- +

The total energy requirements of a person over the course of an entire day, including rest and sleep as well as actual physical activity.

The quantity of output divided by the amount of all inputs used in production.

Diverse inputs (labor, capital, energy) typically are aggregated with an indexing procedure; such as, one in which the quantity of each input is its share in the total cost of production.

In a given population, a statement of the total number of children that would be born to a representative woman, if she were to live to the end of her reproductive years and have children at various age levels in accordance with the prevailing age-specific fertility rates.

The number of British thermal units (BTU, btu) produced by the combustion at constant pressure of one cubic foot of a fuel, under standard conditions of temperature and pressure.

A British thermal unit is a widely used unit of measure, generically defined as the average amount of energy required to produce a change in temperature of one degree Fahrenheit (F) in one pound of pure liquid water; often specified as occurring at standard atmospheric pressure and a specified temperature increase; equivalent to about 1055 joules or 252 calories.

The trapping of light by refraction and reflection at critical angles inside a semiconductor device, so that it cannot escape the device and must eventually be absorbed by the semiconductor.

The total mass of the physical materials that are mobilized each year to support an economy.

This includes not only the direct use of resources for producing goods; such as, oil and timber harvest; but also "hidden flows" including mining overburden, processing waste, and soil erosion; as well as, the materials embodied in imports.

The quantity of organic compounds dissolved in water, measured as pure carbon.

The TOC of a body of water affects biogeochemical processes, nutrient cycling, biological availability, and chemical transport and interactions. It also has direct implications for drinking water quality and wastewater treatment.

The total amount of tiny airborne particles or aerosols present in the atmosphere at a given time.

These can be produced by natural processes; such as, evaporation, forest fires, volcanic eruptions, or pollen dispersal, but TSP measurements usually refer to pollutants from human sources including fuel combustion, coal burning, municipal waste incineration, and so on.

All of the solid particles in wastewater, effluent, or a natural body of water that will not pass through a filter of a given size; components may include silt, decaying plant and animal matter, industrial wastes, and sewage.

A high TSS concentration can have a significant effect on an aquatic system resulting in slowing photosynthesis and reducing oxygen levels.

1. Of or pertaining to a system of government that tolerates only one political party, to which all other institutions are subordinated, and which usually demands the complete subservience of the individual to the State.
2. A leader or member of a totalitarian party; an advocate or supporter of totalitarianism.

1. The whole amount.
2. The state of being complete or total.
3. The sum or total amount of something.
4. The stage, or phase, of an eclipse (of the moon) when light is completely obscured.

1. To a complete degree or to the full or entire extent.
2. A reference to emphasize how good, bad, or complete something is; informal, or slang: "I totally hate this!"
3. Entirely; wholly; completely.

1. Having all four toes united by a web; a reference to certain sea birds; such as, pelicans, cormorants, and gannets.
2. Certain water birds that have webbing that connects each of the four anterior toes or have all four toes fully webbed.

A division of swimming birds including those that have totipalmate feet.

The ability shown by many, if not all, living cells to form all of the types of tissues that constitute mature organisms: Totipotency may be achieved even if the cells have completely differentiated, provided that the appropriate balance of nutrients and hormones is given.

The best example of this phenomenon is the formation of adventitious embryos in carrot tissue cultures. Totipotency demonstrates that each cell retains the full genetic potential of the species.
