The reduction of diffusion drug distance will be possible due to the new design of multiple polymer layer structure, in each of layers with different concentration of the drug, and will lead to drug permeability decreases, and thereby it all will be enable to drug release extension, for prevention of neo intimae growth.
The weight ratio of Paclitaxel of the multiple polymer layer was made, in order to guarantee reduction its rate of diffusion, so that its top level are containing PLGA/15%PEG with 30%wt PTX.
Hemolytic ratio of the films: S1-S3: PLGA /PEG blend films with different PTX loadings (10%, 20%, 30%), S4: multiple layer coated PTX Represented in Fig.5 data are shown that hemolysis rate of multiple layer is of approximately 1.24%, and value of hemolysis drug loading rate of multiple layer was less than the critical value of 5%; it indicates that this coating in contact with the blood did not produce significant hemolysis.

Statistical Analysis.Statistical analysis was performed by the first author with SPSS 10.0 software, and all data were expressed as Mean ± SD.The cytotoxicity grade was evaluated by the one-way analysis of variance.The statistical significance was defined as P<0.05.
Fig. 2 Morphologies of cultured fibroblastic cells on the surface of films for 3 days: (a)-PLGA; (b)-PLGA/BG Cellular Proliferation.The proliferation of fibroblast cells on the PLGA and PLGA/BG was evaluated by the reduction of MTT to formazan by mitochondrial succinate dehydrogenase in complex II (succinate–ubiquinone oxidoreductase complex) [14].
The level of reduction of MTT into formazan reflects the level of cell metabolism.

The present work is at first to examine the GBCDs of 304 stainless steel which were cold rolled with different thickness reduction followed by annealing at 1173K for different time-span.
The strain (thickness reduction) was varied from 6% to 50% and the annealing was completed in vacuum sealed quartz capsules at 1173K for 24h, 48h and 96h, respectively.

Preliminary size reduction was carried out with a roll mill and particles with a size range of 2 - 4 mm carbonized at 500, 700, 750, 800, 850, 900, 950 and 1000 0C for 1 hour each in a limited supply of air using Carbolite furnace, model CF 1200[1].
Low abrasion resistance leads to loss of adsorbent particle integrity and formation of dust particles resulting in reductions in the rate of filtration and the amount of regenerated carbons [2,6,7].
Experimental data showed that the increase in carbonisation temperature resulted in better adsorbent properties of the activated carbon produced.

This may be attributed to the addition of fly ash[15], as the addition leading to a reduction in the quantity of C3A and the pozzonlanic reaction of fly ash leading a reduction of CH.
And the results showed consistency with data from traditional methods.

Furthermore, the proportion of losses due to the PWM harmonics experiences a reduction from no load to load operation.

For EV, the reduction of aerodynamic drag is an important aim pursued, in order to extend the range of EV with certain power and to decrease power consumption of EV in certain range.
A Comparison of On-Road Aerodynamic Drag Measurements with Wind Tunnel Data from Pininfarina and MIRA[C].
Numerical Study on the Wake Flow Characteristics and Drag Reduction of Large-Sized Bus using Rear Spoiler[J].

A separation of the peak due to each diffraction plane was achieved through curve fitting of the experimental data.
The reduction of amorphous area resulted in the increase of crystallinity.
The reduction in this peak intensity can be found.

After the reduction of charge and electrokinetics potential, the particles present a natural association face-toface type.
The face-to-face flocculation create a system with a more closed structure then in the house-of-card flocculation and this contribute to a collapse and reduction of rheological parameters.
From the data in Table 3 and according to Miano and Rabaioli [6], in the dispersions of Bofe clay treated with Na2CO3 followed by Mg(OH)2 there is a tendency to a face-to-face interaction, while in the dispersion of Chocolate and Verde-lodo clays also treated with Na2CO3 followed by Mg(OH)2 the main types of interaction are face-to-face and/or edge-to-edge.

Domestic and foreign fine hematite ore beneficiation technology Foreign fine hematite ore beneficiation technology World iron ore resources are enrich, according to the United States Geological Survey data of 2009,the global iron ore reserve base is 3500 hundred million ton(according to the iron content was calculated to be 1600 hundred million ton ).The global iron ore is abundant, relatively concentrated distribution, the six top iron ore resources are these countries: Ukraine, Russia, China, Brazil, Kazakhstan, Australia, in total global reserves (including iron calculation ) accounted for77.5%.
Thus, flotation column in desulfurization and silicon reduction of iron concentrate plays an important role.
According to the ore property, Gong Changling ore dressing plant has worked with the Changsha Research Institute Of Mining and China Mining University, taken the lead in the domestic launch technology of flotation column research to reverse flotation iron element and silicon reduction for the concentrate of magnetic separation, can obtain high grade iron concentrate which iron grade is 69.15%, the content of Si02 is 4.40%,the recovery of iron is 95.81% ,ideal industrial test of operating parameters is that: the reagent of twelve amine is 160 - 180g/t, roughing cycle slurry pressure is 0.30MPa, slurry concentration is 40%-45%.Using flotation column conduct once rough twice scavenging process, compared with the existing flotation machine which has quintic section roughing quartic concentrating,and roughing middlings return to regrinding process, flotation column simplify the process and realize the short flow separation.
