Binary elements

Line compounds. These are phases where sublattice occupation is restricted by particular combinations of atomic size, electronegativity, etc., and there is a well-defined stoichiometry with respect to the components. Many examples occur in transition metal borides and silicides, III-V compounds and a number of carbides. Although such phases are considered to be stoichiometric in the relevant binary systems, they can have partial or complete solubility of other components with preferential substitution for one of the binary elements. This can be demonstrated for the case of a compound such as the orthorhombic Cr2B-type boride which exists in a number or refractory metal-boride phase diagrams. Mixing then occurs by substitution on the metal sublattice. [Pg.120]

In a series of papers, Szabo et al. (1990 a,b) used a variety of stationary phases, including octadecylsilica (ODS), cyanopropyl, ethylsilica, and immobilized humic acid, to investigate the relationship between Koc and RP-HPLC capacity factors for 11 aromatic hydrocarbons. While capacity factors generated with all the stationary phases showed significant correlations with log Koc, the authors concluded that the immobilized humic acid column capacity factors, obtained by extrapolation of retention data from binary elements to 100% water, gave the best correlation. [Pg.180]

The positions of the velocity values, so far distributed in cylindrical coordinates, are converted to Cartesian coordinates. The liquid flow rate is estimated by multiplying each velocity value V(x,y) with its corresponding binary element B(x,y). [Pg.19]

Mixed Elements. Clearly, it would be advantageous from a nomenclature point of view to have elements composed by combinations of operations via Og, Oc, and Ob. These can be easily introduced but are also subject to reactivity restrictions, leading to a third rule. Rule 3 binary element combinations formed by operations not part of the ring under consideration behave as single elements and cannot be separated into jnore simple elements. Togther with Rules 1 and 2, this Rule 3 eliminates ambiguous reactions in most of the cases of interest. There may be more complex combinations that Rules 1, 2, and 3 do not completely define. In each case, isomorphic or homomorphic elements may exist but can be reached as per discussion above. [Pg.612]

The system of the homoleptic ( binary ) element-ferrocenyl compounds is more limited than that of the corresponding element-phenyl compounds. Whereas stable homoleptic a-phenyl derivatives of almost all main group elements (Groups 1, 2 and 13 — 17) have been characterized, the corresponding Periodic Table of the main... [Pg.236]

The watermark message m is represented by a vector u of binary elements (u e 0,1 ). u can include different information, e.g., an identifier of the copyright holder, a verification bit vector f, and/or the date of computation of the molecule data. Further, the watermark embedding is dependent on a key K, wliich is only known to the copyright holder and perhaps a trusted third party. [Pg.8]

This result identifies the X operator as a twofold rotation in a plane perpendicular to the z-direction. Hence, a twofold rotation axis, C2, and its double group extension KC2 belong to the same class only if the group contains additional binary elements in a plane perpendicular to this axis. Otherwise, the first rule will apply. The exception referred to in this theorem is illustrated by the class structure as shown in Table 7.4. [Pg.180]

Computer Circuits. Shannon showed how logic could be used to design and simplify electric circuits. For example, consider a circuit with switches p and q that can be open or closed, corresponding to the Boolean binary elements, 0 and 1. A series circuit corresponds to a conjunction because both switches must be closed for electric current to flow. A circuit where electricity flows whenever at least one of the switches is closed is a parallel circuit this corresponds to a disjunction. Because the complement for a given switch is a switch in the opposite position, this corresponds to a negation table. When a circuit is represented in symbolic notation, its simplification may use the laws of logic, such as De Morgan s laws. The simplification may also use tables in the same way as the analysis of the equivalence of propositions. [Pg.50]

Additionally, one of the most common binary elements is zinc. In order to remain available in the vicinity of the walls, it requires a pH close to neutral or just slightly acid in the system water, depending on the formulation. [Pg.216]

Even if resource are defined by binary states, it is considered not only [0,1 as state values but [l,m]. In this way function can be characterized by multi-state. In this case, if we refer to the Multi-State System theory, LERP are now considering as non-homogenous MSS with binary elements. It... [Pg.957]

The end-over-end tumble of binary star systems is an excellent source of gravitational waves in both the LF and HF bands. The gravitational wave frequency increases with the total mass of the system, and is inversely proportional to the separation of the binary elements. Thus, compact binaries composed of neutron stars and/or stellar-mass black holes radiate at the highest frequencies since the elements can get very close together without merging. [Pg.105]
