The respiratory quotient (RQ or respiratory coefficient) is a dimensionless number used in calculations of basal metabolic rate (BMR) when estimated from carbon dioxide production.
Priestley's first volume of Experiments and Observations on Different Kinds of Air outlined several important discoveries: experiments that would eventually lead to the discovery of photosynthesis and the discovery of several airs: "nitrous air" (nitric oxide, NO), "vapor of spirit of salt" (later called "acid air" or "marine acid air ...
However, in a Coulomb explosion imaging experiment, an instantaneous image of the molecular structure can be deduced. Such an experiment [ 21 ] has been performed for carbon dioxide. The result of this experiment, and the conclusion of theoretical calculations [ 22 ] based on an ab initio potential energy surface of the molecule, is that none ...
In actuality, however, plants do not absorb all incoming sunlight (due to reflection, respiration requirements of photosynthesis and the need for optimal solar radiation levels) and do not convert all harvested energy into biomass, which results in a maximum overall photosynthetic efficiency of 3 to 6% of total solar radiation.

Experiments might be categorized according to a number of dimensions, depending upon professional norms and standards in different fields of study. In some disciplines (e.g., psychology or political science), a 'true experiment' is a method of social research in which there are two kinds of variables.
A FACE experiment began at Duke University in June 1994. The Blackwood Division of the Duke Forest contains the Forest-Atmosphere Carbon Transfer and Storage facility. This consists of four free-air CO 2 enrichment plots which provide higher levels of atmospheric CO 2 concentration and four plots that provide ambient CO 2 control. [ 5 ]

The history of scientific method considers changes in the methodology of scientific inquiry, not the history of science itself. The development of rules for scientific reasoning has not been straightforward; scientific method has been the subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of ...
