The Suspension Solids are solidified grains over 1mm and can be removed by gravity settling or the filtration method [1] Once the turbidity has intensified, it results in a heavier operating load for each unit in the Purifying Plant thus affecting the output of the water supply [2].

The development of grinding motorized spindle with high power and high rotational speed together with more efficient linear motor drives, in addition to the well-performed grinding wheel, has created the conditions to shorten machining times and to reduce the number of machining operations required while improving the machining quality.
Grinding wheel speed Grinding wheel speed Fig.1: Mechanism of ultra-high-speed grinding Alternatively, increasing the workpiece speed while assuming all other parameters constant can reduce the length of time the abrasive grain in contact with the workpiece which can make the grinding heat sources transfer faster on the workpiece surface and reduce the quantity of heat into the workpiece, which, consequently, improves the heat dissipation conditions and reduces the tendency of the workpiece thermal damage and generation of cracks.
Compared to conventional feed drives, using a rotary motor and a ball screw, the linear motor has a significantly reduced number of moving components.

Silica fine fillers have a number of significant advantages due to their chemical nature which are high water resistance, abrasion resistance, chemical inertness and durability. [5]
Low demand for silica fine fillers on the market today is caused by the fact that until recently silica flour was obtained as a minor product of sand quarrying using old-fashioned grinding machinery which resulted in unstable quality.
Insufficient number of studies on silica flour impact on dry-mix mortars performance may be another reason.
Adding fine fillers to the formulation helps to optimize grain-size composition and, consequently, to increase the contact area between an adhesive and a substrate as well as between an adhesive and a ceramic tile.

Although INAA offers high sensitivity and low detection limits for certain REEs, the technique can only determine a limited number of REEs at a time due to matrix activation and other interferences.
Despite a considerable number of new studies on sample introduction techniques in ICP-MS applications, especially in the analysis of geological samples, solution nebulization remains the preferred method.
Comparative studies for determining the accuracy of the methods using XRF analysis demonstrated that fusion bead is better for phosphor-silicate samples and iron ores, though it is true that the method eliminates the grain size effects and mineralogical effects in the powder sample analysis [13].

Introduction
A large number of vibration systems are included in the running electromechanical or automobile.
Some alloys with high damping capacity at room temperature may lose their good performance when the temperature is too high, for an example, TiNi alloys usually lose their high damping due to the loss of a large number of interfaces once the martensite phase is converted to the parent phase above 373K [2].
M2052 has distinct grains with the size of about 82µm, and the twin microstructure can be identified in the upper right corner of Fig. 1c. 3. 2 Tensile properties Fig. 2 shows the stress-strain curves measured by the tensile test of the samples.

This type of breakage is mostly observed in the case comprising complex and aesthetic designed femoral head articulation, it also discovered that consummate head comprises higher grain size which decrease the wear of the working surfaces [31], [35], [85], [86].
The alumina material comprises larger grain size, lower thickness along with high porosity, this combination can cause the terrible increase in wear rates[31], [51], [85], [86], [88].
The polymer comprises the wear test, higher impact test and low grain sizes.
The metallic’s blends are produced through two different type of production strategy, which comprises material with grain size of under 10 microns for designing and for casting of material grain size is considered from 30 to 1000 microns [110].
The escalation of the progress respecting to THA materials deployment, which comprises factors like the expenditure increases with increase in the number of hip arthroplasties.

The current research
investigates this effect in a series of simple forming tests using a number of different metal
specimens.
This result is consistent with previous findings that ultrasonic excitation leads to a reduction in the forming force and in the break force which can be explained by effective material softening due to the acoustoplastic effect [5] and dependency on factors such as acoustic impedance, internal friction, lattice imperfections, flow resistance, grain boundaries and impurities [6,7].

In Ukraine there is a tendency to increase the number of man-made emergencies, which directly affects the state of the environment and the population.
The extraction process is diffusive - the solvent selectively extracts the oil from the prepared material of the pre-press grain.
