Factor characterized

Dimerization of the Ce-zinc cluster transcription factors involves an a-helical coiled coil in the dimerization region. Coiled coils, often called leucine zippers, are also found in a large group of transcription factors that do not contain zinc. The leucine zipper is made up of two a helices in a coiled coil with every seventh residue leucine or some other large hydrophobic residue, such as isoleucine or valine. Leucine zipper transcription factors (b/zip) include factors characterized by heterodimerization, for example Fos and Jun. The a-helical DNA-binding motifs of the heterodimers recognize quite different base sequences and are continous with the a helices of the zipper.

The studies of emission of adsorbed active particles from the surface of solids due to effects of various factors characterizes the broad capacity of the method of SCS to study the accompanying physical and chemical phenomena. On the other hand this process encounters several problems which should be overcome during identification of these particles. Moreover, in above examples we also illustrate the techniques of application of SCS to solve more complex analytical problems. 

The goal of factor analysis (FA) and their essential variant principal component analysis (PCA) is to describe the structure of a data set by means of new uncorrelated variables, so-called common factors or principal components. These factors characterize frequently underlying real effects which can be interpreted in a meaningful way.

Equation 1.34 is plotted for a number of hydrides in Fig. 1.25. As can be seen all the data points fit very well in a simple straight line whose slope is equal to AS -130 J mol" K [162]. This clearly shows that the entropy term is, indeed, a nearly constant value for all the solid state hydrogen systems. Figure 1.25 also shows that a low desorption temperature at 1 atm of pressure (more or less an operating pressure of a PEMFC) can only be achieved with hydrides having the forma-tion/decomposition enthalpies not larger than 50 kJ moF. For example, hydrides that desorb at room temperature such as LaNi and TiFe have AH 30 and 33.3 kJ mol", respectively [163]. However, too small an enthalpy term would require at 1 atm to be much below 0°C. From this point of view the enthalpy term is one of the most important factors characterizing any hydride.

Two factors characterized most of the waters sampled in the monitoring program. The factor loadings for Factor one indicate that the following chemical species participate in correlated behavior that permits the separations and distinctions described above alkalinity, bicarbonate, B, Cl, conductance, F, Li, Mo, and Na. To simplify discussions in the plots shown earlier this group of species was called the salinity factor. Specific conductance in natural waters usually correlates well with hardness and not as well with bicarbonate, but the current study finds specific conductance closely related to bicarbonate and unrelated to hardness (Ca, Mg, sulfate). This indicates that the ions responsible for increased conductance are probably not calcium or magnesium, rather they are more likely sodium, fluoride, and chloride. 

The second important factor, called the hardness factor for simplicity, includes contributions from Ba, F, hardness. Mg, TDS, Sr, and sulfate. This factor characterizes the upper aquifer waters. One may rationalize the distinction between upper and lower aquifers by hypothesizing a natural "softening" in the lower aquifer where ion-exchange of calcium, magnesium and sulfate occurred with sodium and fluoride. It is Interesting to note that fluoride occurs in both factors and it alone provides a good aquifer identifier.

All of the growth factors characterized so far are proteins (table 24.7). Many of them are cleaved from larger precursors. The 53-amino-acid epidermal growth factor (EGF) is cleaved from a precursor of 1,168 amino acids. This precursor is a membrane-spanning protein, with the EGF moiety and nine related sequences in the extracellular domain. EGF is homologous to several other growth factors,...
