Detection of plastic debris degrading into micro particles across all oceanic environments and inside of marine organisms is no longer surprising news. Microplastic contamination now appears as one of the world’s environmental main concerns. To determine the levels of microplastic pollution at sea, wat...
Seventeen years after treatment establishment, ten individual soil subsamples of each plot were randomly taken at 0.00–0.10 m depth with a galvanized-steel probe (69-mm-diameter) to compose the sample. The samples were separated into two subsamples: subsample 1 to air dry and then homogenized...
VTis the total percentage (VT = 100),Riis the particle radius (mm) of theisize class andRmaxis the radius of the largest particle class (Rmax = 1, in this study). The particle diameter is taken as the upper sieve sizes. Taking logarithms on both sides of Equation (1), the...

D50 value of the sediment particle was 0.5557 mm, as it is the average value for the transported bedload based on Helley-Smith measurements. In addition, the D∗ was also calculated based on the average D50 value of each cross-section’s bed sediment, which had been sampled in October ...
Soil samples were air-dried and crushed into fine-grained particles with a median diameter of less than 2 mm. Then 2 g of the sample was weighed and poured into 20 mL of 60% HNO3. Moderate boiling was carried out for 2 h. After cooling, 3 mL of 30% H2O2 was added, followed by ...
there was no significant difference for K, Ca and Cu in peak intensity and area between ≤2 mm particle size and the aggregate soil, while peak intensity and area for Ti were significantly different. Because fine grinding is time-consuming, soil without grinding could be considered in XRF work...
*It is almost superfluous to say that the large squares of muslin, of which on account of their peculiar nicety we have recommended the use for straining many sweet preparations, must never have a particle of starch in them; they should he carefully kept free from dust and soil of any ki...
The number 5040 is also used in calculating 31680, the sub-lunar distance around the New Jerusalem. The number 31680 is also six miles in feet (6 x 5280). Interestingly, the diameter of the Earth in miles is 8 x 9 x 10 x 11 = 7920. The matching number for 351 in the last row...
The potential is truncated and shifted to zero at a distance of 3.5σσ, where σσ is the mean diameter. The temperature TT is in units of ϵ/kBϵ/kB, where kBkB is the Boltzmann constant, wave vectors are in units of σ−1σ−1, and times in units of √mσ2 /ϵmσ...
