Increased sequential ordering

The currently used (R,S)-nomenclature of asymmetric C-atoms and similar tetracoordinate configurations is based upon the sequential order of the ligands derived from the CIP rules. If one orients an asymmetric C-atom in such a manner that the fourth ligand points backwards, the indices of the first three ligands of an (I )-configuration increase in a clockwise pattern, and counterclockwise for an (S)-configuration. 

Usually the start-up cost is large compared to the transfer cost for a single data unit, and both costs increase sharply (order of magnitude) for each level in the memory hierarchy. Because parallel computers have more levels than sequential ones, these transfer costs are significantly more intrusive on parallel computers and are evident in the performance of parallel applications. 

As the pH increases in order to precipitate magnesium, the equilibrium solubility of silicate increases. In other words, the equilibrium concentration of the magnesium ion cannot be kept low by Eq. (73) to satisfy the demands of the downstream process and still be high to drive the reaction (72). The method outlined above therefore appears to be a nonequilibrium process that depends on the sequential precipitation of the two species. 

The peaks of the sensitivity functions follow in the same sequential order as does the tracer in going from the arterial inflow into the cell. The relative magnitudes of the influences of each of the parameters on the solutions is dependent on the values for the others, in a particular way. When values for PS(. are high and are low then the sensitivities to PS and V are increased. This is simply to state the obvious, namely that the sensitivity is greatest to the rate limiting feature of the transport. 

A large group of multi-phase polymeric systems is formed by the block copolymers, graft copolymers, random copolymers, and poly-blends. This group of polymers has received increasing attention (e.g. 27—29) because of the controllable, tailor-made properties of these engineering materials. Here the superstructure is determined by the relative weight, sequential order, and Hmited miscibihty or even incompatibility... 

In acidic solutions, equiUbtium is achieved more slowly. Polymerization of smaller species appears to occur sequentially a given polymer species first increases in size and then disappears, presumably because of its inclusion in higher order polymers. Depolymerization of siUcate species appears to be rapid, because crystalline Na2Si02 and Na2H2Si04 8H2O yield equivalent distributions of siUcate species in water upon dissolution. 

The first situation, for parallel pathways, is illustrated by Eq. (6-9), the reaction between H2O2 and I". The limiting order with respect to [H+] increases from zero to one as [H+] increases. The second situation, for sequential reactions, is illustrated by Eq. (6-14). The order with respect to [Fe2+] falls from two to one with increasing [Fe2+], and that with respect to [Fe3 r ] from zero to negative one with increasing [Fe3+]. 

Sequential addition of monomers 6 7-26-27-114) is the most obvious procedure. Once the first monomer has been polymerized, the resulting living species is used as a polymeric initiator for the polymerization of the second one. The monomers are to be added in the order of increasing electron affinity to provide efficient and fast initiation 26 U4). This condition is rather restrictive, and the number of monomer systems that can be used is limited (Table 5). Moreover, when the second monomer contains an electrophilic function (e.g. ester) which could lead to side reactions, it is necessary to first lower the nucleophilicity of the living site. This is best done by intermediate addition of 1.1-diphenylethylene25). The stabilized diphenylmethyl anions do not get involved in side reactions with ester functions, while initiation is still quantitative and fast. 

Therefore, such sequential in situ reactions are always carried out either in order to prepare a substance for a color reaction that is to follow or to increase the amount of information that is obtained by exploiting a combination of different independent reactions. This provides information that could not be obtained using one single reagent. 

The periodic table lists the elements In order of Increasing atomic number. Because the number of electrons in a neutral atom Is the same as its atomic number, this list is also in order of increasing number of atomic electrons. Hydrogen, with Z = 1 and one electron, appears first, followed sequentially by helium (two electrons), lithium (three electrons), and so on.
