The pH scale is, as previously mentioned, an inverse logarithm and ranges from 0 to 14 (Figure 1). Anything below 7.0 (ranging from 0.0 to 6.9) is acidic, and anything above 7.0 (from 7.1 to 14.0) is alkaline. Extremes in pH in either direction from 7.0 are usually considered ...
The pH scale is used to determine whether a substance is acidic or basic, and to calculate how strong a chemical it is. A pH value is a number that ranges from 1 to 14 for most common chemicals, with seven being the middle or neutral point. Values below 7 are indicators of acidity, ...
Fig. 1: Past changes in the range sizes of mammals, birds and amphibians. aEstimated changes in range sizes between 1700 and 2016, relative to potential natural ranges in 1850 (which are based only on the natural biome distribution and assume no land use; ‘Methods'). Coloured areas represe...
These 60 items should be rated each on a 5-point Likert scale (0 = strongly disagree to 4 = strongly agree). The NEO-FFI’s objectivity, factorial structure, and validity are supported by previous findings [82,83]. The homogeneity of the five subscales ranged between α = 0.72 and ...
The coefficient γ ranges between 0.05 and 0.17 for UHPFRC, with fiber volume fractions between 0.02 and 0.04. Matrix Young’s Modulus typically ranges between Em≈ 40 to 55 GPa, and the steel fiber modulus of elasticity is in the range Ef≈ 200 to 210 GPa. 𝑤𝑑𝑒𝑏=𝜏𝑙2𝑓...
Fluid that is swept up between the jet and the wall is accelerated near the plate, and pressure decreases in that region. Therefore, the pressure produced on the wall is lower than the surrounding pressure, and the lowest pressure is noted at a certain distance from the corner. As a ...
The particulate fraction of phosphorus will influence the relationship between turbidity and TP where turbidity is a stronger surrogate for TP concentration when the particulate fraction is higher (Jones et al., 2011; Schilling et al., 2017). The Grand River is the source of ~45% of annual ...
Financially influential investors from outside the farming sector with a vested interest in operating a variety of biogas plants in capacity ranges that are above average seem to gain influence rapidly [9]. The frame of the presented research projectd is set by this national contrast between the...
Accordingly, the contact resistance between the overlapping areas increased, and it was reflected by the change of the total resistance of the device. Since the maximum sensing range of the sensor was determined by the initial (0 strain) overlapping area of PEDOT:PSS layers, which was related ...
including alternating mountain ranges, midlands, lowlands, and a small section of the East Sea (Fig.1c). The target area for precipitation estimation using ANN was placed inland inside D2 (hereafter, D2T; Fig.1b), between latitudes 20.5°N–22.5 °N and longitudes 104°E–107°E, coverin...
