A large variety of drug delivery systems are described in the literature, such as liposomes (Torchilin, 2006), micro and nanoparticles (Kumar, 2000), polymeric micelles (Torchilin, 2006), nanocrystals (Muller et al., 2011), among others. Microparticles are usually classified as microcapsules or microspheres (Figure 8). Microspheres are matrix spherical microparticles where the drug may be located on the surface or dissolved into the matrix. Microcapsules are characterized as spherical particles more than Ipm containing a core substance (aqueous or lipid), normally lipid, and are used to deliver poor soluble molecules... 

Muller et al. focused on polybead molecules in the united atom approximation as a test system these are chains formed by spherical methylene beads connected by rigid bonds of length 1.53 A. The angle between successive bonds of a chain is also fixed at 112°. The torsion angles around the chain backbone are restricted to three rotational isomeric states, the trans (t) and gauche states (g+ and g ). The three-fold torsional potential energy function introduced [142] in a study of butane was used to calculate the RIS correlation matrix. Second order interactions , reflected in the so-called pentane effect, which almost excludes the consecutive combination of g+g- states (and vice-versa) are taken into account. In analogy to the polyethylene molecule, a standard RIS-model [143] was used to account for the pentane effect.

The diffusion of ions through the polymer matrix has been investigated by Muller. 85 The mobility of the different analytes were found to parallel the diffusion constants of oxygen and ammonia and Table 7.3 describes ion diffusion in several polymers. Accordingly, the development of a polymer matrix for a specific application...

Extensive studies performed by several leading quantitative bioanalytical laboratories indicate that matrix effects can be limited by selecting the appropriate sample preparation techniques (Muller et al., 2002) and selecting the appropriate internal standard (Matuszewski, 2006).

Buser and Muller found B8-1413 (P-26), B9-1679 (P-50), and six further chlo-robornanes (TCI, TC2, TC5-TC8) in penguin tissue [120], TC8, tentatively identified as B8-806/B8-809 (P-42), was present in low amounts [120], Some of the other components may be B8-1412, B8-1414 (P-40), B8-1945 (P-41), B8-2229 (P-44), which have been identified in the same matrix [100]. Usually, in biota from the top level of the food chain B8-1413 (P-26) and B9-1679 (P-50) were most abundant. In addition, the number of toxaphene peaks decreased with increasing trophic level. The results obtained so far can be summarized as follows. Most of the toxaphene components are degradable, and only a few persistent congeners are accumulated in higher organisms. 

Twinning is common in wollastonite (Deer, Howie, and Zussman 1963 Muller and Wenk 1975). The twin axis is 1010] and the composition plane (100). Figure 8.7(c) shows a twin lamella (one unit cell wide) in an untwinned matrix. To eliminate very severe misfit at the composition plane, a relative displacement of R = [OlOJ is necessary.

Transfer functions have been derived using algebraic methods based on the Hausdorff formula (Chandrakumar et al., 1986 Visalakshi and Chandrakumar, 1987), analysis in the zero-quantum frame (Muller and Ernst, 1979 Chingas et al., 1981 Chandrakumar et al., 1986), with the help of a Young tableau formulation (Listerud and Drobny, 1989 Listerud et al., 1993), and by application of Ldwdin projectors to evaluate density matrix evolutions (Chandrakumar, 1990).

The determinant of the —> distance matrix D. In an isomeric series, this index takes same values for all compounds, alternating from negative values for isomers with an even number of nonhydrogen atoms to positive values for compounds with an odd number of nonhydrogen atoms [Schultz, Schultz et al., 1990, 1993]. For acyclic alkanes with a number A of atoms, the following relation holds [von Knop, Muller et al., 1991] ...
