Excerpts

Furthermore, although the D was not a significant factor in the tensile strength degradation of the BFRP, it was somewhat significant in the case of the GFRP.

At present, there has been an increasing trend for biomimetic nano-HA to be used as a preventative agent for oral care products [ 17 ].

In each case, a positive trend is observed: as impact energy increases, the average microstructural measures increase concurrently.

Similarly, if there is less inclination, then it has very slight significance, so in our case, the sliding speed has slight significance.

Although in this case the use of the HiPIMS coating did not produce a significantly better machined surface quality, when compared to the dc MS-obtained coated tool, the increase in wear resistance is quite significant.

The results of the preliminary research by the authors suggest that the thermal effect of this process on the material cut may be significant.

They distinctly identified the need to fabricate high-performance hybrid aluminium composites and reported that the mechanical properties particularly the tensile strength improves up to a certain extent, i.e., 3 to 5 wt.% of SiC; however, beyond this range, the tensile strength showed a decreasing trend.

Our study found no significant change but a slight trend of reduction on the hindfoot eversion and forefoot abduction.

Two types of behavior can be seen here: first, a decreasing trend at lower frequencies, and then an increasing trend at higher frequencies.

In addition, when OSP mass content was kept constant, the slope in the rising part (O–A) indicated an increasing trend for specimens in each group as curing time increased. 4.2.

[ 11 ], the impact of desert sand replacement rate on the compressive strength of high-strength concrete showed a trend of first increasing and then decreasing.

Carbon and glass fibre metal laminates present an increasing trend of the force as the impact develops, the trend continues up to a maximum value, where the force start to decrease.

The analysis of the coefficient d f / d t , which describes the laminate capacity to accumulate energy through the elastic deformation with correlation to permanent deformation [ 43 ] was presented in Figure 5 , it can be observed a positive trend with the impact energy.

Furthermore, a decreasing trend in the maximum force in the fibres can be observed with an increasing number of cycles due to relaxation phenomena in the fibre–matrix interface or the fibre itself.

Deviations of the slope of the measured and simulated force-displacement relationships becomes moderately significant when the head displacement reaches approximately 0.11 mm.

With the increase of V R , the compressive strength of HFRC gradually decreased, the splitting tensile strength and flexural strength showed a trend of first increasing and then decreasing; when V R increased from 5% to 10%, the splitting tensile strength and flexural strength of HFRC increased by 1.03% and 0.61%, respectively; when V R increased from 5% to 15%, the compressive strength, splitting tensile strength and flexural strength of HFRC decreased by 5.98%, 6.48% and 4.69%, respectively. 3.3.

The current density values are in an increasing trend for the other three samples and the substrate 0 h sample experiences a higher value of the current density (1.69288259 × 10 −5 A/cm 2 ).

The other substrate samples exhibit a decreasing trend in their oxide content and the values are 21.46%, 20.67% and 17.06% for the 18, 70, 0 h substrate (316L steel) samples.

There was no indication that in the range of 5–15% of limestone content, there is a clear trend linking the amount of limestone to the change in yield stress.

The result revealed that, as the annealed temperature increased, the contact angle showed a decreasing trend.

Furthermore, none of our test materials showed a clear trend towards M1 or M2 polarization.

In contrast, the use of isopropanol as diluting alcohol generated particles which showed a strong trend to increase in size at higher calcination temperatures.

The results revealed a decreasing trend in tensile strength with increasing CWP content.

Thus, from a macroscopic point of view, the flow stress of the composite still showed an increasing trend with increasing deformation.

The solubility of both drugs was determined as a function of temperature (293.15 to 313.15 K) and IL composition, following an increasing trend with the increase in both conditions.
