Augmentation/augmented nets

Henle (e.g., furosemide, bumetanide, and torsemide) and distal convoluted tubule (thiazides), have most commonly been associated with the generation of metabolic alkalosis. These agents promote the excretion of sodium and potassium almost exclusively in association with chloride, without a proportionate increase in bicarbonate excretion. Collecting duct hydrogen ion secretion is stimulated directly by the increased luminal flow rate and sodium delivery, and indirectly by intravascular volume contraction, which results in secondary hyperaldosteronism. Renal ammoniagenesis may also be stimulated by concomitant hypokalemia, further augmenting net acid excretion. 

Decorated nets. These are formed by replacing the nodes by different types of polyhedra. One example of a decorated dia net is shown in figure 4.13. Augmented nets are a special case of a decorated net. 

The O Keeffe principle of augmented nets was not only a tool for describing complex structures in a simple manner, but was also very inspiring for the synthe-... 

Once the richness of the field was discovered, it was necessary to rationalize the synthesis of MOFs to provide tailor-made architectures. At the beginning, the reticular chemistry of the augmented net concept of O Keeffe et al. [56] was nicely applied for defining the chemical and topological rules governing this possible design. The derived structures of MOF-5 [4] provide the most famous example of this approach. 

Baffles are responsible for restricting the tangential velocity component, u, and augment the vertical component, while simultaneously increasing the radial velocity, U,. The net result is that the liquid discharges from the impeller in a wider flow radius. 

In recent years there has been much activity to devise methods for multivariate calibration that take non-linearities into account. Artificial neural networks (Chapter 44) are well suited for modelling non-linear behaviour and they have been applied with success in the field of multivariate calibration [47,48]. A drawback of neural net models is that interpretation and visualization of the model is difficult. Several non-linear variants of PCR and PLS regression have been proposed. Conceptually, the simplest approach towards introducing non-linearity in the regression model is to augment the set of predictor variables (jt, X2, ) with their respective squared terms (xf,. ..) and, optionally, their possible cross-product... 

Electronic spectra of oxadiazoles were studied <2003IJB429>. MRINDO/S calculations augmented by singly excited Cl were performed on oxadiazoles. Net charge distributions, ionization potentials, and electronic spectra of oxadiazoles were reported. The Rydberg transitions were also discussed. 

The hypho (Gr.. net ) series of boranes, with electronic formula 2n + 8, has beer suggested to augment the closo, nido, and arachno series. Although no neutral boranes fit this scheme, some borane derivatives do. It is also passible to construct units consisting of more than one of the above types. These are called cmjuncio (Latin, joined subunits ) structures. 

With the augmentation of the net flow, the disjoint P-V paths are determined step by step. And, finally, by (8), we can decide whether G is Kekulean or not. 

Equation 11.17 is the fundamental expression of the PARAFAC (parallel factor analysis) model [77], which is used to describe the decomposition of trilinear data sets. For nontrilinear systems, the core C is no longer a regular cube (ncr x ncc x net), and the non-null elements are spread out in different manners, depending on each particular data set. The variables ncr, ncc, and net represent the rank in the row-wise, columnwise, and tubewise augmented data matrices, respectively. Each element in the original data set can now be obtained as shown in Equation 11.18 ... 

Enzyme induction can be problematic with co-administration of benzodiazepines and rifampicin or certain anticonvulsants (phenobarbital, phenytoin, carbamaze-pine). However, despite enzyme stimulation, the net effect of adding these anticonvulsants can be augmentation of benzodiazepine-induced sedation.
