It includes also weeding and change of temperature to control pests.Food Race: American environmental author Daniel Quinn coined the term Food Race (by analogy to the Cold War's "nuclear arms race") to describe an understanding of the current overpopulation emergency as a perpetually escalating crisis between growing human population and growing food production, fueled by the latter. Quinn argues that as the worldwide human population increases, the typical international response is to more intensely produce and distribute food to feed these greater numbers of people.Evolution in Variable EnvironmentAcyl-homoserine-lactone synthase: Acyl-homoserine-lactone synthase (, acyl-homoserine lactone synthase, acyl homoserine lactone synthase, acyl-homoserinelactone synthase, acylhomoserine lactone synthase, AHL synthase, AHS, AHSL synthase, AhyI, AinS, AinS protein, autoinducer synthase, autoinducer synthesis protein rhlI, EsaI, ExpISCC1, ExpISCC3065, LasI, LasR, LuxI, LuxI protein, LuxM, N-acyl homoserine lactone synthase, RhlI, YspI, acyl-[acyl carrier protein]:S-adenosyl-L-methionine acyltranserase (lactone-forming, methylthioadenosine-releasing)) is an enzyme with system name acyl-(acyl-carrier protein):S-adenosyl-L-methionine acyltranserase (lactone-forming, methylthioadenosine-releasing).

To avoid the possible confusion with the regular rings and regular local rings of commutative algebra (which are unrelated notions), von Neumann regular rings are also called absolutely flat rings, because these rings are characterized by the fact that every left module is flat.Pyrites Island: Pyrites Island () is the largest of three small islands lying northeast of Gam Point and forming the east side of Esther Harbor, off the north coast of King George Island in the South Shetland Islands.
