the water does not cover the inside surface uniformly, but remains dispersed into drops. The same effect is seen on a dirty windshield; turning on the wipers simply breaks hundreds of drops into thousands. By contrast, water poured over a clean glass surface willwetit, leaving a uniform film...
Advance treatments or tertiary wastewater treatment: these processes are normally applied when secondary treatment is not adequate. Some of these processes may remove up to 99% of BOD5 and phosphorous, all suspended solids and bacteria, and 95% of nitrogen. They can produce sparkling clean, colorl...
In the Finnsjön field test (Moreno et al., 1983) the condition of the fracture surface is not known. The regression analysis of the breakthrough curve indicated that the matrix diffusivity was much higher than that of intact granite. The matrix diffusion would account for most of the ...
The latter likely buffered centennial-scale variability due to the rainfall amount effect over this interval, and might result in an internal variability (or absence of it) that is not linked to the amount of precipitation. A prevailing influence of the source effect in our oxygen record in ...
Not as far out as some promotions, but the "scientific studies" they quote are mostly irrelevant. The one published scientific article they cite is in an obscure Egyptian journal! AquaKat structured water Penergetic, the maker of this device, claims that it "functions as a kind of signal ...
Average helium abundance is 4.5 × 10−9 ccSTP/g for the 240 m and 1500 m depth samples by wet experiment with water (STable 3). On the other hand, reacted water and hot blank water had much higher δ18O and δD values than those of the initial water, probably due to ...
On the other hand, the Moran's I value is showing a weak autocorrelation at a significance level of α < 0.1 in the wet season, which suggests a localization in water quality. Similarly, high and weak positive spatial autocorrelations are obtained for the NH3-N trend in the dry ...

These are papers linked to an earlier topical volume/collection, report-type papers, or timely papers dealing with a ...
furthermore, a large portion of urban runoff often infiltrates diffusely and does not reach the swales at all. Therefore, a more sustainable approach, is to avoid biocide pollution at the source88,89, which would allow a targeted urban water management by SIS that preserves urban groundwater ...
Similarly, evaluating whether ΔR/P differs significantly from zero, we found that DECREASE treatment significantly increased the R/Ps of seven combinations with relatively low ecosystem complexity, but this is not the case for the other one with relatively high ecosystem complexity (Fig. 1a–c)....
