The reflection coefficient acquires higher values in the case of dust grains of fixed charge in comparison with the case of fluctuating charge on the dust grains.
The effective temperature of the plasma is also found to alter the solitary structures significantly in the case of dust grains having fluctuating charge.
In the case of dust explosion venting, the maximum pressure Pmax generated in a given vented industrial enclosure is not only influenced by inherent dust parameters (dust chemistry including moisture, and sizes and shapes of individual dust particles).
It is noteworthy to mention here that even in the case of dust acoustic solitary waves in an unmagnetized plasma with kappa-distributed electrons and ions, only negative potential nonlinear structures were reported if the dust is negatively charged [58].
The (i, j) element of S y is the covariance of y i and y j, which is 〈 y i − 〈y i 〉)(y j − 〈y j 〉)〉, where 〈y i 〉 stands for the expectation value of y i (1 ≤ i ≤ 11, see Table 5 for the case of dust retrieval).
The geometric mean of B-Pb was 30 μg/L in case of dust as a single contamination source, 36 μg/L for paint, 70 μg/L for water, 38 μg/L for soil, and 38 μg/L for unusual sources.
It's a case of dusting yourself down, getting together and going again".
"It was a case of dusting myself down, recovering, getting stronger and tougher and thinking: 'Right, I need to go and prove that again'.
Three spacecraft potential profiles represent the cases of zero dust current (dotted line), 8 km s-1 spacecraft speed (solid line), and 16 kmspeedpeedashash line).
The dispersion Eq. (12) carries a term ( alpha^{2} ), it means the same results are expected for the cases of positively charged dust grains and negatively charged dust grains.
As in the case of the dust model parameters, we use normalized values of P and Y in order to evaluate their sensitivities.
