Properties of fluoroanhydrite compositions at the age of 7 days Composition Strength [MPa] Electric resistivity [Ohm] Bending Compression H 7,16 27,3 16849 R 10,2 34,9 16770 NC 6,7 8,85 5752 G 9,8 24,9 16847 TEG 8,4 29,8 1516 According to the data obtained (Table 1, diagram - Fig. 4), the introduction of crushed technogenic graphite turned out to be ineffective, since it did not affect the electrically conductive properties of the composition, while its strength decreased by 28.7%.
Optimal results in improving the electrical conductive properties were achieved when the plasticized fluoroanhydrite composition was modified by thermally expanded graphite in the amount of 7% by the weight of fluoroanhydrite, which allowed the reduction in the electrical resistance of the material by 11 times with an insignificant drop in strength (up to 15%).

At each point of the experimental area, the results were determined using data from four parallel measurements.
Presumably, the overall reduction in cellulose content is, among other reasons, relative due to contamination of the unused waste of flax and cotton with dust, residues of combustible and lubricating liquids and other fine materials present in the technological processes.

Vertical flammability tests performed on treated cotton fabrics demonstrated that the P-based sol-gel coatings are efficient in the significant reduction of the total burning time, in particular when the DBTA catalyst is not used, by producing the highest residue.
Main combustion data of treated cotton samples assessed by cone calorimetry.

Vijayalakshmi [5] used continuous distribution kinetics to determine the degradation rate coefficient from the experimental data.
Hydroxyl radicals generated via the iron catalysed Haber-Weiss reaction from the superoxide radical formed by the reduction of dissolved oxygen during the xanthine oxidase catalysed oxidation of xanthine have been shown to degrade PAM [23].

The welding arc is an extremely dynamic and variable process, continuously affected by a number of physical and metallurgical disturbances [3] such as: - ionization process of gases and metal vapour; - deposition and transfer of melted weld metal and slag; - metallurgical reactions of reductions and refinement of weld metal in puddle.

However, the decrease of flying height will cause the occurrence of intermittent contacts, which lead to slider wear, the loss of data and even catastrophic failure of hard disk drive.
More precise simulation of slider-disk interaction dynamics is required for the reduction in the slider-disk spacing.

Then, in the high temperature tube furnace, the synthesis was performed at 1300 oC for three hours with a weak reductive atmosphere of flowing 5%H2-95%N2 which ensured complete reduction of Eu3+ to Eu2+.
The 1800s data were recorded.

Therefore, Chen and Lee [11] developed an intelligent fuzzy weighted estimator with higher target tracking performance and better noise reduction effectiveness.
The input estimation method uses the recursive form to process data.

The data demonstrate that the residual carbon source (ethanol) could be used for denitrifying reaction of next cycle, but the relative denitrifying rate will was decreased with the ethanol solution reused times.
Thus, the reductions of nitrate and nitrite were limited due to insufficient carbon source at these days.

Zhao[4] experiments that adopted axial vibration, the normal grinding force can be reduced by 1/3 to 1/4, and the across axis direction leads to a significant reduction of grinding forces and an increase in material removal rate while maintaining a slightly increase in wheel wear and surface roughness.
Measure equipments includes: ONO SOKKI LV-1710 Laser Doppler Vibrometer systems to measure the tiny amplitude; KISTLER Type-9257B dynamometer; Mitutoyo SJ-301 Surface Roughness Measurement; Sartorius RC 210 D Data Weighing Systems measures the amount of removal material; JEOL JSM-5610LV SEM to observe surface formation.
