Term distribution

Equilibriuin Distribution Ratio or K factor. This is also termed distribution coefficient... [Pg.350]

The dimensionless K. is regarded as a function of system T and P only and not of phase compositions. It must be exfjerimentally determined. Reference 64 provides charts of R (T,P) for a number of paraffinic hydrocarbons. K. is found to increase with an increase in system T and decrease with an increase in P. Away from the critical point, it is invariably assumed that the K, values of component i are independent of the other components present in the system. In the absence of experimental data, caution must be exercised in the use of K-factor charts for a given application. The term distribution coefficient is also used in the context of a solute (solid or liquid) distributed between two immiscible liquid phases yj and x. are then the equilibrium mole fractions of solute i in each liquid phase. [Pg.350]

At this stage, it will be appropriate to introduce the term distribution coefficient (KD)... [Pg.521]

Definition of a Complex Polymer. A simple polymer is one vrtiich has at most one broad molecular property distribution (e.g., a broad molecular weight distribution). A complex polymer is one which has two or more broad molecular property distributions (e.g., a broad molecular weight distribution and a broad copolymer composition distribution) ( ). Properties such as molecular weight and composition, Aiich can be in so much variety in a polymer that they must be described as a distribution, are here termed "distributed properties". It is the presence of simultaneous breadth (i.e., variety) in more than one distributed property which is the defining characteristic of a "complex" polymer and the source of analysis difficulties. [Pg.60]

Both concentrations should be calculated per unit volume of the phase. The term "distribution constant" is recommended in preference to the term "partition coefficient" which has been used with the same definition. [Pg.563]

Enzyme-catalyzed polymerization reactions have an important characteristic that is not found elsewhere. Once the enzyme has added a monomeric unit to the growing chain, it can either dissociate and recombine at random with other growing termini, or it can remain attached to the same chain and add further residues. Enzymes that dissociate between each addition and distribute themselves among all the termini are termed distributive. Those that process along the same chain without dissociating are termed processive. These terms apply also to degradative enzymes such as exonucleases. [Pg.216]

Production network design by definition needs to include distribution decisions. For the purpose of this classification a model is considered to include distribution network design only if at least one distribution echelon (warehouses, distribution centers, etc.) is explicitly modeled. The term "distribution center" is not defined uniformly in literature (cf. Higginson and Bookbinder 2005). Here, distribution centers where a production step takes place are considered to be a production echelon whereas those performing picking or packaging operations are considered to be a distribution echelon. [Pg.55]

Parenteral administration of radium to humans results in short-term distribution to soft tissue which is rapidly followed by deposition of most of the radium in the skeleton (BEIR IV 1988). [Pg.32]

The transition from desktop computing to embedded systems is associated with price, power and timing constrains. A special class embedded systems, termed distributed sensor networks (DSN), are characterized by extra requirements small size and sufficient battery lifetime. Distributed sensor networks can be alternatively labeled mobile ad-hoc networks (MANET). While the term DSN is associated with data acquisition applications, MANET emphasizes mobility and the lack of infrastructure. Distributed sensor networks can be scalable to thousands of nodes that cooperatively perform complex tasks. The interaction between the nodes is based on wireless communication [Kah 00, War 01, Hil 02], Wireless sensor networks (WSN) is yet another synonym. [Pg.177]

Since Kc may be independent of the solute concentration, but will always be a function of the temperature (and pressure), the term distribution coefficient is to be preferred to the alternatives distribution constant and equilibrium constant. If the distribution isotherm is linear, Kc will also equal the ratio of average concentrations in eqn.(1.8), and hence... [Pg.4]

Liver and kidney Since the liver and kidney not only influence the long-term distribution and clearance of anesthetic agents, but also... [Pg.118]

Explain the term distribution coefficient (or partition ratio) for a solute distributed between two nearly immiscible liquids. Given feed-stream flow rates and compositions for a liquid extraction process and either solute distribution coefficient data or a triangular phase diagram, calculate the product stream flow rates and compositions. [Pg.240]

Be able to read and understand in general terms, distribution diagrams that depict metal complexation as a function of ligand concentration or pH. [Pg.119]

Notice that here we use the concept of distribution in a non-rigorous statistical sense. In rigorous statistical terms distribution usually alludes to the cumulative distribution function. Here, as in common language, by distribution we mean what in rigorous statistical terms is denoted as density function or probability function . [Pg.6]

In order to properly evaluate the temporal trends between metals, their annual data sets were examined with reference to a number of previous studies. As seen in Fig. 4, a long-term distribution of Pb derived by combining aU data sets exhibited a notable reduction of its concentration through the years. [Pg.92]

On the operational level it is assumed that parameters are known and deterministic. It is to decide about the short-term distribution of the considered chemicals in the network such that the total operational costs for transport, turnover, and storage are minimized. More precisely, it is to decide about... [Pg.90]

The terms distribute in commerce and distribution in commerce when used to describe an action taken with respect to a chemical substance or mixture or article containing a substance or mixture mean to sell, or the sale of, the substance, mixture, or article in commerce to introduce or deliver for introduction into commerce, or the introduction or delivery for introduction into commerce... [Pg.50]
