The light-harvesting system of PSI uses multiple copies of the same transmembrane proteins used by PSII. The energy of absorbed light (in the form of delocalized, high-energy electrons) is funneled into the reaction center, where it excites special chlorophyll molecules (P700, with maximum light absorption at 700 nm) to a higher energy level.
Research concerning the relationship between the thermodynamic quantity entropy and both the origin and evolution of life began around the turn of the 20th century. In 1910 American historian Henry Adams printed and distributed to university libraries and history professors the small volume A Letter to American Teachers of History proposing a theory of history based on the second law of ...

In physical chemistry, the Arrhenius equation is a formula for the temperature dependence of reaction rates.The equation was proposed by Svante Arrhenius in 1889, based on the work of Dutch chemist Jacobus Henricus van 't Hoff who had noted in 1884 that the Van 't Hoff equation for the temperature dependence of equilibrium constants suggests such a formula for the rates of both forward and ...
On the other hand, it was not well known until the middle of the 20th century that infants also required the presence of warmth and affection, known as "maternal warmth". The greatest number of dependency needs seem to be encompassed in infancy, but dependency needs begin to change and decrease with age and maturity. This marked decrease in ...
On the other hand, in its version for identifying power-law probability distributions, the mean residual life plot consists of first log-transforming the data, and then plotting the average of those log-transformed data that are higher than the i-th order statistic versus the i-th order statistic, for i = 1, ..., n, where n is the size of the ...
Initially at Grateful Life, Hamm wasn’t allowed to bring in non-spiritual materials like novels or newspapers — a restriction inherited from the older “therapeutic community” models — or to wear street clothes. He attended classes in light blue surgical scrubs, a public humbling that all newbies were subjected to.
