When an excess of freshly prepared DTT (1 mM) was added to the samples without DTT, a progressive decrease of scattered light was seen and followed until a steady state was reached (Figure 2B), indicating a decrease of the average dimensions of the sample species in response to the anti-oxidant effect of DTT.
On the other hand, ham showed no significant water absorption and textural change, resulting in an exponential decay of weight retention, mainly affected by a decrease of the surface area of the sample.
Increasing the reaction temperatures resulted in a decrease of the final density of samples.
After addition of AcOH to the sample, a decrease of the peak intensity at 660 nm was found.
Second, the absorption spectra show narrowing from the short-wavelength side of the spectrum; this region is normally attributed to the absorption of disordered molecules in an amorphous state since molecular absorption of P3HT in diluted solutions is observed just around ~ 460 nm; the above changes therefore indicate a decrease of the disordered amorphous fraction in the sample [6, 8].
The synthesis of nanoparticles supported on activated carbon is accompanied by a decrease of the specific surface area of samples, especially during high temperature carburizing.
Nitrogen isotherms have revealed a decrease of the pore volume in doped samples ascribed to the partial blocking of the pore structure by the embedded nanometric metal oxide particles.
Therefore, finding an optimal set of variables by discarding the uninformative variables from the data can substantially improve the DPLS model by a decrease of the prediction error for test samples or/and a decrease of model complexity.
However, a decrease of the fatigue limit of the UNSMed sample with nitriding for 48 h was induced by the surface defects (small voids) that were produced by the prolonged nitriding.
In general, a decrease of the individual phenolic concentrations in all samples (excepting quercetin-3-rutinoside, as main flavonol in fermented samples with R. oligosporus) was observed (Table 1).
