Latin symmetrical

The design of experiment written in this form is a reconstructed Latin square design where one of the diagonals has been left out. Generally speaking, Youdens square is a symmetrically balanced incomplete random block where each factor level appears once and only once in each block position. 

Youdens square is always a Latin square where one or more columns (or rows or diagonals) have been left out however, the opposite is not true a Latin square where one or more columns (or rows or diagonals) have been left out is not always a Youdens square, for by leaving out columns from a Latin square the balance in design is lost. It is, however, possible to construct designs of Youdens squares from all symmetrical balanced random blocks [26]. Youdens squares have the same number of rows and levels of a researched factor but quite a different number of columns. 

The flowers of mints are bilaterally symmetric. Because they are mostly pollinated by insects, mints have relatively brightly colored, nectar-rich flowers usually grouped into a larger inflorescence The lower, flised petals of the flower provide a platform for pollinators to land on called a lip (or in Latin, labia, from which the family name Labiatae is derived). Most species in the mint family have bisexual flowers, containing both male (staminate) and female (pistilate) organs. The fruits are small, one-seeded nutlets. 

In the de lege symmetry breaking, the potential no longer has a symmetric form, and the rules (Latin word lex = law or rule, de lege meaning by law) for the dynamics show no symmetry. When the departure from exact symmetry is small. 

Systemic lupus erythematosis is named for a symmetric facial rash that occurs early in the disease process. The disease is called systemic because it affects the whole body, and erythematosis means redness of the skin. Lupus, derived from the Latin word for wolf, implies that the disease is a sneaky foe that overwhelms the human body. 

The quantities Pjk are also dielectric material coefficients. Their dimension is obviously reciprocal to the dimension of the permittivity. They are also the coordinates of a symmetric second rank tensor for which several names have been in use. Following Thurston (1974) we call it impermittivity. (Alternatively, the names dielectric impermeability (Cady 1964, p. 163), dielectric permeability (Grindlay 1970, p. 56), vetivity , derived from the latin word vetare as the opposite to the latin permittere (Voigt 1910, p. 441) have been proposed.) The effect described by Eq. (4.31) is the inverse effect to Eq. (4.30). It is obvious that E and D have exchanged their roles as independent and dependent variables and, therefore, Sij and Pij are material coefficients derived from different thermodynamic potentials.
