The data of growth indicators during control period, yield and total water consumption were obtained.
Data analysis.
The values of all indicators were estimated by averaging the measured data of the three duplications related to each treatment.
Hence, data of growth indicators at 0d, 10d, 20d and 30d after water control were collected.
All these data were analyzed using analysis of variance with the significance level of 95% (alpha=0.05), and using the analysis of nonlinear regression as well.

The percentage of biofilm reduction was 40.8%.
In the case of C. glabrata, no significant biofilm reduction was examined among all groups.

It was found that 0.5% vanillin incorporated resin exhibited significant inhibitory effect against S. mutans biofilm formation with a percentage of reduction of 40.8%.
The results of this study were in agreement with our previous study on orthodontic resin [21] which reported 30% S. mutans biofilm reduction in 0.5% vanillin incorporated resin compared with a control.

It is shown that the kinetics of softening between mill passes can be modeled more simply when the normalized strain (reduction) per pass is employed rather than the conventional strain.

When corrections to the downstream stands are made in this way, the pass reductions (and consequently the pass speeds) are changed locally causing further variations in the softening kinetics.
By contrast, with the θ-based approach, the value of the strain hardening rate in successive stands can be readily computed, the changes in the softening kinetics assessed and fed forward, and then the pass reductions corrected accordingly to minimize the variations in gauge and microstructure.
This allows for: 1) A radical reduction in the number of experiments required to generate sufficient data for modeling the post-deformation softening behavior; 2) A description of "strain accumulation" due to incomplete interpass softening in multipass hot rolling in terms of the strain hardening rate. 3) Significant simplification of the extrapolation of laboratory results to industrial high strain rate multipass processing.

Results Reduction of Ag+ into Ag0 was primarily observed by visual color change from yellowish (Fig. 3.
Table 1: The wavelength, color & Ph change, time taken for reduction and nature of the AgNPs.
Harzianum responsible for the excellent reduction properties [16].
The results obtained from the XRD pattern (Figure 06 below) which suggest the presence of crystalline structure of AgNPs with an average size of 14.76 nm are in good agreement with HrTEM data .
The obtained data was compared with standard antiobiotic streptomycin (1.16±0.13 mm) as positive control, while aqueous silver nitrate (0.86±0.08 mm) and aqueous fungal extract (0.00 ± 0.00 mm) as negative control.

In Fig. 1, the plotted experimental data were collected from several samples of different preparation (free, with water, and with oil), and using from 8% to low deformation levels.
This effect is associated to a creep reduction after the pause.
The evolution of the energy against the frequency up to 3 Hz is shown by the data points plotted as dots in Fig. 9-a.
In particular, the loop O-e*-M-O is fitted by two cubic polynomials, one for the transformation and one for the retransformation, using the experimental data.
In summary, an efficient simulation is achieved by adopting the phenomenological approach based on the implementation in the USERMAT routine of ANSYS of either a bilinear or cubic fit to the experimental data and on a semi-quantitative approach to model the partial loops.

The mechanical strength briquettes data for low and high stresses of the mixtures briquetting are obtained.
Some data on the efficiency of the liquid glass using are contained in [4 - 10].
In the conditions of industrial production, the reduction of the liquid glass amount in the briquetted mixture is economically justified, which is due to both technological and economic reasons.
For the construction of graphs, the optimal content data of liquid glass in the raw mixes is selected: 3% for iron ore concentrates; and 2% for ferrosilicomanganese.
The automated line briquetting scheme of CJSC Spidermash Conclusion Analysis of the tests results showed the possibility of a significant reduction in binder consumption during the raw mixtures pressing with high compression stresses.

While comparing the formability of adhesive bonded blanks with respect to different orientations, transversely oriented defect shows more reduction than 45° and longitudinal cases.
Introduction Adhesively bonded structures have emerged almost in all structural components fabricating fields with many advantages in terms of design flexibility, weight reduction, cost reduction and ease of fabrication.
It was found that foam density resulted to be the most significant parameter able to affect formability, lower density foams led to a remarkable reduction of defect rate.
After the completion of tensile tests and IPPS formability tests, the load–extension behaviour of all bonded blanks was obtained from the machine data.
The reduction in ‘n’ value of bonded blanks is an indication of reduction in formability.

The ultra-fine silver powders were prepared by chemical reduction using nitric acid silver (AgNO3) as raw material, ascorbic acid (C6H8O6) as deoxidizer and adding polyvinylpyrrolidone (PVP) as dispersing agent.
Tthe reduction capacity of ascorbic acid increasesd with the increase of pH value, because ofowing to the decrease of E value.
(语法有问题) Ascorbic acid has excellent reduction capacity as a kind of unsaturated sugar acid lactone
Thus the reduction rate for the reaction of (1) can be adjusted by changing pH value.
The lattice constant calculated from this pattern were 2.359, 2.044, 1.444 and 1.231, which agree with the published data JCPDS. 4.Conclusion The ultra-fine silver powders with spherical, controllable size (0.5~2μm) have been synthesized via a wet chemical reaction.
