The principal constituents are usually calcium, magnesium, sodium, and potassium cat ions and carbonate, bicarbonate, chloride, sulphate, and nitrate anions.
First-constituent frequency has been repeatedly shown to have a rapid but lasting effect on eye movements as judged by an effect on first fixation and gaze durations, whereas second constituent frequency is usually important later affecting gaze duration (Andrews, Miller, & Rayner, 2004; Hyönä & Pollatsek, 1998; Juhasz et al., 2003; Pollatsek, Hyönä, & Bertram, 2000).
DRAWING up a common European manifesto that can satisfy all the constituent national parties is usually a triumph of generality over particulars.
Following the construction in [17 19], GLD codes are defined using a sparse matrix constructed by replacing each row in a sparse parity-check matrix, which indeed defines an LDPC code, with rows including one copy of the parity-check matrix of the constituent code Here, is usually a block code of code length n and information bit length k, such as BCH code and Reed-Solomon (RS) code.
Due to currently unavailable quantification methods, the measurement of structural constituents on sections is usually difficult and the results are often doubtful [ 24].
While in constituent-quark models confinement is usually implemented via potential terms of an infinitely rising nature (of, e.g., harmonic-oscillator or linear type), in QCD the particularities are more delicate (for a recent review of the problems surrounding quark confinement, see e.g. [28]).
As organic inorganic hybrid composites, natural biological materials exhibit superior mechanical properties such as toughness and strength in comparison with their constituent phases: the organic phase is usually very soft and the inorganic phase very brittle.
Although tin is usually a minor constituent in alloys, it is an essential one on account of the way in which its special properties confer improvements to the matrix metal.
The position of the constituent atoms of a macromolecular structure is usually determined either through X-ray crystallography for the larger structure or through nuclear magnetic resonance (NMR) for the smaller molecules.
The cell-to-cell spread of cytoplasmic constituents such as nonenveloped viruses and aggregated proteins is usually thought to require cell lysis.
