Trichloroethylene (TCE) is a halocarbon with the formula C 2 HCl 3, commonly used as an industrial metal degreasing solvent. It is a clear, colourless, non-flammable, volatile liquid with a chloroform-like pleasant mild smell [3] and sweet taste. [9] Its IUPAC name is trichloroethene. Trichloroethylene has been sold under a variety of trade names.
The nonlexical pathway is thought to be more active and constructive as it assembles and selects the correct subword units from various potential combinations. For example, when reading the word "leaf", that its spelling adheres to sound rules, the reader must assemble and recognize the two-letter grapheme "ea" in order to produce the sound "ee ...
Dopaminergic pathways (dopamine pathways, dopaminergic projections) in the human brain are involved in both physiological and behavioral processes including movement, cognition, executive functions, reward, motivation, and neuroendocrine control. [1] Each pathway is a set of projection neurons, consisting of individual dopaminergic neurons.
“Speaking of Synthesis means approaching the guiding principle of Assagiolian psychology, both the means and the goal of the entire psychosynthetic pathway. . . Synthesis is a process that involves the creation of a relationship between two or more elements through a third entity, in order to create a new reality. [5]
Many organochlorine compounds have been isolated from natural sources ranging from bacteria to humans. [3] [4] Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids.
Trichloroethylene is a major byproduct, which is separated by distillation. Worldwide production was about 1 million metric tons (980,000 long tons; 1,100,000 short tons) in 1985. [11] Although in very small amounts, tetrachloroethylene occurs naturally in volcanoes along with trichloroethylene. [12]
Ethylene signaling pathway is a signal transduction in plant cells to regulate important growth and developmental processes. [ 1 ] [ 2 ] Acting as a plant hormone , the gas ethylene is responsible for promoting the germination of seeds, ripening of fruits, the opening of flowers, the abscission (or shedding) of leaves and stress responses.

In psychology, a drive theory, theory of drives or drive doctrine [1] is a theory that attempts to analyze, classify or define the psychological drives. A drive is an instinctual need that has the power of driving the behavior of an individual; [2] an "excitatory state produced by a homeostatic disturbance".
