Horst structure

The European HDR project site at Soultz-sous-Forets is located on a local horst structure in the Rhine Graben, where Hercynian age granites are covered by a 1.4 km thick sedimentary section (Baria et al., 1999). Well GPK-1 was drilled to 3,590 m depth (open hole below 2,850 m depth), and since 1987 it has been used for a number of... 

The workflow has been applied to two fields offshore mid Norway, where the motivation was to obtain an objective fault interpretation and to enhance small-scale heterogeneities produced by small faults. The two fields are located close to each other and are covered by the same data set (Figure 7). The first field is defined by a horst structure with relatively horizontal layers. The simple geometry makes it easy to verify the automatically extracted internal faults with manual interpretation in the seismic data. The second field, which is the main focus in this work, is defined by a large and strongly rotated fault block. This field is structurally much more complex with locally intensive internal deformation.

Thus, the role of the defect labile structures in the thermal degradation of PVC, which is the key to the Frye and Horst mechanism of stabilization, is itself debatable. The Frye and Horst mechanism—the substitution of labile chlorines by more stable groups—has also been criticized.

A Comparison of the secondary structures of the acidic and basic forms of BmPBP, determined by NMR (Horst et al., 2001a) and X-ray crystallography (Sandler et al., 2000), respectively, and that estimated from the primary structure of the protein with the prediction program PHDsec (Rost and Sander, 1993).

Between pH 5.5 and 6.5, there is a dramatic increase in binding, suggesting that an amino acid with a pKa 6.0 has a strong effect on pheromone binding. Because this ionization is seen for all PBPs studied so far, the most likely candidate for this effect is one (or more) of the conserved histidine residues. Recently, the structure of the acid form of B. mori PBP was solved (Horst et al.,... 

The first chemical clue relating the structure of anesthetics to their potency was discovered in 1899 by a pharmacologist, Hans Horst Meyer, and an anesthetist, Charles Ernst Overton. Working independently, Meyer and Overton noted a strong correlation between the polarity of a compound and its potency as an anesthetic. They expressed polarity as the oil/gas partition coefficient, while anesthetic potency was expressed as the partial pressure in atmospheres. Figure 11.10 is a Meyer-Overton correlation for 18 anesthetics used on mice. Note that olive oil is used, and it has become the most commonly used reference solvent. 

Extensive reviews on global optimization can be found in Horst (1990) and Horst and Tuy (1990). In this section we present a summary of a global optimization method that has been developed by Quesada and Grossmann for solving nonconvex NLP problems which have the special structure that they involve linear fractional and bilinear terms. It should be noted that global optinuzation has clearly become one of the new trends in optimization and synthesis, and active workers involved in this area include Floudas and Visweswaran (1990), Swaney (1990), Manousiouthakis and Sourlas (1992), and Sahinidis (1993).

It must also be recognized that, because of the usually much finer subdivision of natural ion exchangers in soils as compared with commercial synthetic resins, surface phenomena may play a more prominent role. Among these effects are water is more structured at the interface than in the bulk liquid ions and water molecules are less mobile at the interface because of stronger interactions the dielectric constant of water is lower than in the bulk solution and surface charges produce an electric double layer (Horst, 1990).
