It contains elements based in the cosmology of Taoism [349] and considers the human body more in functional and vitalistic than anatomical terms. [ 350 ] [ 351 ] Health and illness in TCM follow the principle of yin and yang and are ascribed to balance or imbalance in the flow of a vital force , qi .
Pseudoscience can have dangerous effects. For example, pseudoscientific anti-vaccine activism and promotion of homeopathic remedies as alternative disease treatments can result in people forgoing important medical treatments with demonstrable health benefits, leading to ill-health and deaths.
By analogy with Example 1, the purely relational connectives defined on W can be axiomatized naively in terms of atoms and pairs of atoms in the customary manner of introductory texts. The pure theory of binary relations can then be obtained as the theory of the pseudoelementary class of reducts of models of this elementary class obtained by ...
Examples of symmetrical pseudohalogen compounds (Ps−Ps, where Ps is a pseudohalogen) include cyanogen (CN) 2, thiocyanogen (SCN) 2 and hydrogen peroxide H 2 O 2. Another complex symmetrical pseudohalogen compound is dicobalt octacarbonyl, Co 2 (CO) 8. This substance can be considered as a dimer of the hypothetical cobalt tetracarbonyl, Co(CO) 4.
A relative pseudocomplement of a with respect to b is a maximal element c such that a∧c≤b. This binary operation is denoted a→b. A lattice with the pseudocomplement for each two elements is called implicative lattice, or Brouwerian lattice. In general, an implicative lattice may not have a minimal element.
For example, somewhere between 30 and 44% of the human genome consists of repetitive elements such as SINEs and LINEs (see retrotransposons). [7] [8] In the process of retrotransposition, a portion of the mRNA or hnRNA transcript of a gene is spontaneously reverse transcribed back into DNA and inserted into chromosomal DNA.
The pseudopotential is an attempt to replace the complicated effects of the motion of the core (i.e. non-valence) electrons of an atom and its nucleus with an effective potential, or pseudopotential, so that the Schrödinger equation contains a modified effective potential term instead of the Coulombic potential term for core electrons normally found in the Schrödinger equation.
Suppose that k is a non-perfect field of characteristic 2, and a is an element of k that is not a square. Let G be the group of nonzero elements x + y √ a in k[√ a].There is a morphism from G to the multiplicative group G m taking x + y √ a to its norm x 2 – ay 2, and the kernel is the subgroup of elements of norm 1.
