Pharmacokinetics is based on mathematical modeling that places great emphasis on the relationship between drug plasma concentration and the time elapsed since the drug's administration. Pharmacokinetics is the study of how an organism affects the drug, whereas pharmacodynamics (PD) is the study of how the drug affects the organism.
Pharmacodynamics. Pharmacodynamics ( PD) is the study of the biochemical and physiologic effects of drugs (especially pharmaceutical drugs ). The effects can include those manifested within animals (including humans), microorganisms, or combinations of organisms (for example, infection ). Pharmacodynamics and pharmacokinetics are the main ...
A peak experience is an altered state of consciousness characterized by euphoria, often achieved by self-actualizing individuals. [citation needed] The concept was originally developed by Abraham Maslow in 1964, [citation needed] who described peak experiences as "rare, exciting, oceanic, deeply moving, exhilarating, elevating experiences that generate an advanced form of perceiving reality ...
The peak–end rule is an elaboration on the snapshot model of remembered utility proposed by Barbara Fredrickson and Daniel Kahneman.This model dictates that an event is not judged by the entirety of an experience, but by prototypical moments (or snapshots) as a result of the representativeness heuristic.

The Bass model or Bass diffusion model was developed by Frank Bass. It consists of a simple differential equation that describes the process of how new products get adopted in a population. The model presents a rationale of how current adopters and potential adopters of a new product interact. The basic premise of the model is that adopters can ...
1. World population growth 1700–2100, 2022 projection. Population projections are attempts to show how the human population statistics might change in the future. [ 1] These projections are an important input to forecasts of the population's impact on this planet and humanity's future well-being. [ 2] Models of population growth take trends ...
The Hubbert peak theory says that for any given geographical area, from an individual oil-producing region to the planet as a whole, the rate of petroleum production tends to follow a bell-shaped curve. It is one of the primary theories on peak oil. Choosing a particular curve determines a point of maximum production based on discovery rates ...
Peak oil. A 1956 world oil production distribution, showing historical data and future production, proposed by M. King Hubbert – it had a peak of 12.5 billion barrels per year in about the year 2000. As of 2022, world oil production was about 29.5 billion barrels per year (80.8 M bbl /day), [ 1] with an oil glut between 2014 and 2018.
