Efficiency differences

Lipoxygenase AVNTR polymorphism in 100 bp upstream from the ATG start codon is associated with transcription efficiency. Differences in response to 5-lipoxygenase inhibitors and leucotriene receptor antagonists. 

Both Figures 7.16 and 7.17 illustrate the difference in operating temperature range for both DeNO, systems and show their efficiency difference. NO,. Trap presents a narrow...

A comparison of the thermal efficiency of the Diesel cycle with that of the Otto cycle shows that the two thermal cycle efficiencies differ by the quantity in the brackets of Eq. (3.23). This bracket factor is always larger than one, hence the Diesel cycle efficiency is always less than the Otto cycle efficiency operating at the same compression ratio. 

The efficiency of trapping of cortisol on different SPE solid phases is shown in Figure 6.42. The large efficiency difference observed highlights the need for... 

Alkyl trifluoromethyl ketones were hydrogenated with [Rh(OCOCF3) (S)-Cy,Cy-oxoProNOP ]2 in toluene under 20 atm of H2 to give the corresponding chiral alcohols in high ee (Scheme 7) [27]. Trifluoromethyl was efficiently differ-... 

There exists an important difference between GA and CEA assumptions about the HTR inlet temperature. Can this temperature difference explain efficiency differences ... 

Two causes seem available to explain the efficiency differences between GA and CEA flow sheets temperatures and couplings. 

Some studies have demonstrated that the source of polyhedra does not affect its lethality or the time necessary to kill the caterpillars (Faulkner and Henderson, 1972 Ignoffo et al., 1974 Wang et al., 1992 Chakraborty et al., 1999). However, Bonning et al. (1995) found that polyhedra produced from caterpillars kill Trichoplmia ni and Heliothis virescens caterpillars faster than polyhedra from cell culture. This could suggest efficiency differences of these polyhedra produced from different sources. Nevertheless, there were no observed differences in lethal dose between the polyhedra tested. 

It could be thought that the small efficiency differences were relevant on the PAH emissions. However, by comparing the data obtained from LCL runs No 3, 4 and 5, at which the same efficiency value is reached but the emitted PAH amount was different, and those obtained from LCL runs No 2 and No 4, with very close efficiencies but at which the emitted PAH amount were the most extreme values detected, it can be deduced that this influence is negligible and the small differences among the high efficiencies reached in all the runs carried out do not seem to be the only determinant effect on PAH emissions. These results allow inferring the importance of the pyrosynthesis step on the PAH emissions, when a limestone-coal blend is added to the reactor. 

It is frequently assumed that the absorption spectrum of a test substance will accurately represent its activation or action spectrum because only absorbed radiation can bring about a photochemical change. Frequently neglected are solvent (bathochromic or hypsochromic) or matrix effects such as polarity, pH, complexation, dimerization, binding, self-filtering, and quantum efficiency differences between various absorption bands, etc., which may occur. 

We observed die wetting, splashing, and bouncing bdiavior of the dn lets coming into contact with the hot metal plate by a high-speed camera. We could thus observe the behavior of the emulsions when coming into contact with the hot metal surface. This helps to explain the product efficiency differences observed. 

The extraction efficiency depends strongly on the nature of the matrix as a result, the best supercritical fluid in terms of analyte solubility may not also be the most efficient. Differences in extraction efficiency for a given analyte under identical conditions arise from the matrix. The presence of functional groups on the surface of the matrix or in its components and their ability to bind to the analytes, the organic matter and moisture... 

The solute solution concentration has been demonstrated to influence DRV encapsulation efficiency differently, depending on the solute. As an example, although glucose and CF entrapment values were found to decrease with increasing solute solution concentration, the same was not found true for encapsulation of sodium chloride and potassium chloride (1). For CF, best encapsulation yields in DRVs are demonstrated when a 17 mM solution in a tenfold dilution of an isotonic PBS buffer, is used. The ionic strength of the buffer used to dissolve the solute added at this step, should be at least 10 times less than that of the buffer used for DRV dilution after the hydration step (see below) in order to reduce material losses, due to osmotic activity of liposomes. 

This does not mean that bounds on time complexity would not be interesting. However, on the one hand, no approach at proving non-trivial ones seems to be known, and on the other hand, efficiency differences between existing signature schemes with different degrees of security primarily concern communication and storage complexity. 

Values of the Shockley-Queisser limiting efficiency differing by a few absolute percent appear in the literature because of differences in the incident spectra or operating temperature used in the calculations. 

Because of the instability of S at room temperature the quenching of the sulfur melt has to be very rapid and efficient. Different authors have used ice water [20-22], liquid air [23], or sheets of glass [19] or metal [19, 24] onto which the melt was blown by a strong jet of cold gas to produce either a thin film or small particles. Because of the low heat conductivity of elemental sulfur the quenching in water is insufficient and water is not even inert chemically towards hot sulfur. The quenched melt has to be extracted by CS2 at... 

More challenging is the question of how to get the light into the sample with good efficiency. Different methods have been compared in Ref. 72. In the early times of CIDNP, the NMR probe was frequently modified as to allow the insertion of a quartz rod from below, which was either orientated in line with the NMR tube or off-axis. In the first case, the light entered through the bottom of the tube in the second, a prism on top of the quartz rod effected side-on illumination of the region...
