Owing to the large number of types of industrial lubricants, the number of constraints, and therefore the number of desired properties, is very large. The main industrial oils are summarized in Tables 6.4 and 6.5, the first giving the constraints common to all applications, and the second addressing the more specific requirements. A few essential properties appear from these tables ... 

The essential property that we use, is the transformation of the product of convolution in a sum. 

The commercial grades of calcium carbonate from natural sources are either calcite, aragonite, or sedimentary chalk. In most precipitated grades aragonite is the predominant crystal stmcture. The essential properties of the two common crystal stmctures are shown in Table 1. 

In order to understand the operation of the cycle and the ideas put foi"ward later it is useful to look at the essential properties of adsorbent-adsorbate pairs and the way that they are used in the solar refrigerator. 

The system proposed by Freund et al. contained all the essential properties of the modern moving bed, or pseudo moving bed chromatographic systems. The procedure was extended by Scott [6], in 1958, to gas/liquid chromatography and... 

More recently suggested models for bulk systems treat oil, water and amphiphiles on equal footing and place them all on lattice sites. They are thus basically lattice models for ternary fluids, which are generalized to capture the essential properties of the amphiphiles. Oil, water, and amphiphiles are represented by Ising spins 5 = -1,0 and +1. If one considers all possible nearest-neighbor interactions between these three types of particle, one obtains a total number of three independent interaction parameters, and...

The product may be dissolved in alcohol, and on addition of a small quantity of ammonia or sal-ammoniac will exhibit all the essential properties of a tincture of musk. 

Much of what is currently known about spin glasses can be traced back to the pioneering work of Edwards and Anderson [edw75]. Their idea was to try to capture the essential properties of real spin glasses with a simple Jsiug-like Hamiltonian of the form ... 

Electrophysiological studies (mainly using voltage-clamp and patch clamp) revealed the essential properties of the sodium channels kinetics of channel gating and selective ion permeation. Sodium channels are... 

Among the first desirable properties of models are economy in the number of parameters that describe the essential properties of an operation, general applicability to a variety of problems, and successful prediction. 

Radiative Corrections Negaton in an External Field.— The content of the previous sections of this chapter can be summarized by saying that the essential properties of the vacuum- and one-particle states in the absence of external perturbations are that they are steady ... 

S5-S6 loop region in DRKl by the one of NGK2 confers to the recombinant channel the single-channel conductance and TEA sensitivity of NGK2 [47], Thus, a region of approximately twenty amino acids in the primary sequence of K channels controls essential properties of the K" channel pore [48]. 

The essential property of a cementitious material is that it is cohesive. Cohesion is characteristic of a continuous structure, which in the case of a cement implies an isotropic three-dimensional network. Moreover, the network bonds must be attributed to attractions on the molecular level. Increasingly, recent research tends to show that cements are not bonded by interlocking crystallites and that the formation of crystallites is incidental (Steinke et al., 1988 Crisp et al., 1978). The reason is that it is difficult to form rapidly a mass which is both cohesive and highly ordered. 

Where the CRS is to be employed as a verification material in general methods published in the European Pharmacopoeia, then like a CRS used as an assay standard, the extent of testing is considerable. It is desirable that several collaborating laboratories test the proposed substances using a variety of techniques to ascertain that its purity as adequate. An appropriate number of collaborating laboratories will also participate, after the substance has been deemed suitable, in the study to establish a value by the measurement of the essential property of the substance using an appropriate instrument. 

The type of HCT performed depends on a number of factors, including type and status of disease, availability of a compatible donor, patient age, performance status, and organ function. In addition to bone marrow, hematopoietic cells may be obtained from the peripheral blood progenitor cells (PBPCs) and umbilical cord blood. The essential properties of the hematopoietic cells are their ability to engraft, the speed of engraftment, and the durability of engraftment.1... 

Biocides must have a number of essential properties if they are to be successfully used in emulsion paint manufacture (Table 7).

The most characteristic feature of any crystal is its symmetry. It not only serves to describe important aspects of a structure, but is also related to essential properties of a solid. For example, quartz crystals could not exhibit the piezoelectric effect if quartz did not have the appropriate symmetry this effect is the basis for the application of quartz in watches and electronic devices. Knowledge of the crystal symmetry is also of fundamental importance in crystal stmcture analysis. 

Donna Haraway observes that bodies are portrayed not in terms of their essential properties but as strategic systems or information-processing devices. People, she says, are described in terms of design, boundary constraints, rates of flows, system logic.. .. Persons can be reasonably thought of in terms of disassembly and reassembly . 

Approximately 10 billion pounds per year of elastomers are used in the United States. Crosslinking is a requirement if elastomers are to have their essential property of rapidly and completely recovering from deformations. The terms vulcanization and curing are used synonymously with crosslinking. Crosslinking is achieved either by chemical reaction or physical aggregation depending on the elastomer. 

This essential property of IF2 can be tested in at least three different ways, all of which require the availability of f[3H]Met-tRNA and IF2, which are prepared according to the protocol detailed in Milon et al. (2007). However, all the tests described in this section can make use of the sturdier and smaller C domain of Bacillus stearothermophilus IF2, since this domain contains all molecular determinants for the IF2-fMet-tRNA interaction (Guenneugues et al, 2000 Spurio et al, 2000). The method for the preparation and purification of B. stearothermophilus IF2C is essentially that described by Spurio et al. (1993). The concentration of the protein... 

In the NO-SCR by NH3, we note the highest reduction activity and selectivity on catalyst containing both vanadium and molybdenum than catalysts issued containing Mo or V, only. Furthermore, it should be underlined that a higher efficiency is obtained with ZSM-5 as host structure than samples issued from USY and MOR. Where a higher loss of porous volume were observed. On the basis of characterization data it has been suggested that the observed synergism in the SCR reaction is related to the existence of electronic interaction between the V and Mo species. In particular, it has been proposed that the presence of such electronic interactions modifies the catalysts redox properties, which have been claimed an essential property in the NO-SCR by NH3 reaction. 

Biocompatibility is an essential property of new biomaterials for drug delivery. Biocompatibility is always assessed with respect to specific applications and may be assessed with respect to cytotoxicity, allergic responses, irritation, inflammation, mutagenicity, teratogenicity, and carcinogenicity (Katti el al., 2002). The reviews by Katti et al. (2002) and Domb et al. (1997) provide good discussions on the biocompatibility studies that have been conducted with polyanhydrides over the past two decades. 

Despite the fact that the water-solubility of the s-fractions during the heating of their aqueous solutions (above the PST for the p-fraction) is an essential property of protein-like macromolecules, other structural features could also be responsible for such behaviour, including the following ...
