Question: Richard Cumberland wrote plays that involved a process called what?

Context paragraphs:
Richard Cumberland (dramatist): Richard Cumberland (19 February 1731/2 – 7 May 1811) was an English dramatist and civil servant.  In 1771 his hit play "The West Indian" was first staged.  During the American War of Independence he acted as a secret negotiator with Spain in an effort to secure a peace agreement between the two nations.  He also edited a short-lived critical journal called "The London Review" (1809).  His plays are often remembered for their sympathetic depiction of colonial characters and others generally considered to be margins of society.

Colonialism: Colonialism is the establishment of a colony in one territory by a political power from another territory, and the subsequent maintenance, expansion, and exploitation of that colony.  Colonialism involves unequal relationships between the colonial power and the colony and often between the colonists and the indigenous peoples.

Richard S. Muller: Dr. Richard Stephen Muller (born May 5, 1933) is an American professor in the Electrical Engineering and Computer Science Department of the University of California at Berkeley.  He made contributions to the founding and growth of the field of MicroElectromechanical Systems (MEMS).  His seminal contribution of polysilicon sacrificially-released beams in 1982 led to a class of micromanufacturing process called surface micromachining.  This process preceded the creation of low cost, mass-produced commercial micro accelerometers, which are used in automotive collision sensors for airbag deployment.  Together with Richard White, he created BSAC (Berkeley Sensors and Actuators Center), an organization that produced many generations of academic researchers and intellectual properties in the MEMS field, a field that in 2013 accounted for multi-billion dollar revenue worldwide.  He is a member of the US National Academy of Engineering.

Supernova nucleosynthesis: Supernova nucleosynthesis is a theory of the production of many different chemical elements in supernova explosions, first advanced by Fred Hoyle in 1954.  The nucleosynthesis, or fusion of lighter elements into heavier ones, occurs during explosive oxygen burning and silicon burning processes.  Those fusion reactions create the elements silicon, sulfur, chlorine, argon, sodium, potassium, calcium, scandium, titanium and iron peak elements: vanadium, chromium, manganese, iron, cobalt, and nickel.  These are called "primary elements", in that they can be fused from pure hydrogen and helium in massive stars.  As a result of their ejection from supernovae, their abundances increase within the interstellar medium.  Elements heavier than nickel are created primarily by a rapid capture of neutrons in a process called the r-process.  However, these are much less abundant than the primary chemical elements.  Other processes are thought to be responsible for some nucleosynthesis of other such heavy elements, notably, the proton capture process known as the rp-process and a photodisintegration process known as the gamma (or p) process.  The latter synthesizes the lightest, most neutron-poor, isotopes of the heavy elements.

Bone remodeling: Bone remodeling (or bone metabolism) is a lifelong process where mature bone tissue is removed from the skeleton (a process called "bone resorption") and new bone tissue is formed (a process called "ossification" or "new bone formation").  These processes also control the reshaping or replacement of bone following injuries like fractures but also micro-damage, which occurs during normal activity.  Remodeling responds also to functional demands of the mechanical loading.

Downcutting: Downcutting, also called erosional downcutting, downward erosion or vertical erosion is a geological process by hydraulic action that deepens the channel of a stream or valley by removing material from the stream's bed or the valley's floor.  The speed of downcutting depends on the stream's "base level", the lowest point to which the stream can erode.  Sea level is the ultimate base level, but many streams have a higher "temporary" base level because they empty into another body of water that is above sea level or encounter bedrock that resists erosion.  A concurrent process called lateral erosion refers to the widening of a stream channel or valley.  When a stream is high above its base level, downcutting will take place faster than lateral erosion; but as the level of the stream approaches its base level, the rate of lateral erosion increases.  This is why streams in mountainous areas tend to be narrow and swift, forming V-shaped valleys, while streams in lowland areas tend to be wide and slow-moving, with valleys that are correspondingly wide and flat-bottomed.  The term "gradient" refers to the elevation of a stream relative to its base level.  The steeper the gradient, the faster the stream flows.  Sometimes geological uplift will increase the gradient of a stream even while the stream downcuts toward its base level, a process called "rejuvenation."  This happened in the case of the Colorado River in the western United States, resulting in the process that created the Grand Canyon.

Homolysis (chemistry): In chemistry, homolysis (from Greek ὅμοιος, homoios, "equal," and λύσις, lusis, "loosening") or homolytic fission is chemical bond dissociation of a molecule by a process where each of the fragments retains one of the originally bonded electrons.  During homolytic fission of a neutral molecule with an even number of electrons, two free radicals will be generated.  That is, the two electrons involved in the original bond are distributed between the two fragment species.  The energy involved in this process is called bond dissociation energy.  Bond cleavage is also possible by a process called heterolysis.

Endocytic cycle: The whole cycle of endocytosis plus exocytosis is known as the endocytic cycle.  Most animal cells engage portions of their surface plasma membranes in a process called endocytosis.  The main route of endocytosis is the coated pit, which buds into a cell to form a cytoplasmic vesicle—clathrin-coated vesicle.  The membrane so internalised is processed in a series of intracellular organelles, which include endosomes and lysosomes.  Some of this membrane is returned to the cell surface by a process called exocytosis.

Happy Days (1929 film): Happy Days is a 1929 American Pre-Code musical film, notable for being the first feature film shown entirely in widescreen anywhere in the world, filmed in the Fox Grandeur 70 mm process.  French director Abel Gance's "Napoléon" (1927) had a final widescreen segment in what Gance called Polyvision.  In 1927, Paramount released "Old Ironsides" with two sequences in a widescreen process called "Magnascope".  In 1928, MGM released "Trail of '98" in a widescreen process called "Fanthom Screen".

Labile cell: In cellular biology, labile cells are cells that multiply constantly throughout life.  The cells are alive for only a short period of time.  Due to this,they can end up reproducing new stem cells and replace functional cells.  Especially if the cells become injured through a process called necrosis, or even if the cells go through apoptosis. The way these cells regenerate and replace themselves is quite unique.  While going through cell division, one of the two daughter cells actually becomes a new stem cell.  This occurs so then that daughter cell can end up restoring the population of the stem cells that were lost.  The other daughter cell separates itself into a functional cell in order to replace the lost, or injured cells during this process.  Labile cells are one type of the cells that are involved in the division of cells.  The other two types that are involved include stable cells and permanent cells.
