Unveiling Causal Links, Temporal Patterns, and System-Level Dynamics of Freshwater Salinization Using Transit Time Distribution Theory
Inland freshwater salinity is rising worldwide and threatens the quality of our water resources, a phenomenon called the freshwater salinization syndrome (FSS). Simultaneously, the practice of indirect potable reuse (IPR) that augments critical water supplies with treated wastewater to enhance …

Taxonomia e distribuição geográfica dos Monstrilloida (Copepoda - Crustacea) do Atlântico sul ocidental
… Occidental Atlantic specimens are similar to the one found in other places. with some variations in relation to the length of the body. The pattem of antennular armature was described for each species in order to use this feature in future taxonimical comparisons. The fifteen species were …

Interactions Between Copper and Chlorine Disinfectants: Chlorine Decay, Chloramine Decay and Copper Pitting
… that this technique has promise in at least one water condition known to cause pitting. The method also quickly predicted that high levels of orthophosphate could stop pitting attack in this water, whereas low levels would tend to worsen pitting. Future research should be conducted to examine …

THE FREQUENCY-DEPENDENCE OF THE NMR LONGITUDINAL RELAXATION RATE, T(1)(-1), OF WATER IN CYSTS OF THE BRINE SHRIMP (ARTEMIA)
… NMR spin-lattice relaxation rate, T(,1)('-1), of water is independent of the Larmor frequency, (omega)/2(pi), in the normal rf range. However, T(,1)('-1) of intracellular water in biological systems, which accounts for as much as 80% of the cell mass, is frequency-dependent. This indicates that …

The Water/Energy Nexus: Climate, Consumption and Ecosystem Services
<p>Water and energy are drivers of living systems. This work provides an assessment of the Water Energy Nexus in the United States, comparing the well-watered north-east and the arid west. Electric grid systems are most stressed on hot summer afternoons. Grid stress can lead to cascading failures …

Environmental Factors and Management Practices that Influence Salmonella and Listeria Prevalence at the Sub-Field Level on an Eastern Shore of Virginia Farm
… that may impact the prevalence of Salmonella spp. and Listeria spp. at the sub-field level (0.2 ha grids) on an Eastern Shore of Virginia farm. Virginia Tech's Eastern Shore Agricultural Research and Extension Center (ESAREC) farm was used due to the liability of testing for pathogens …

Energy Sensitive Urban Water Planning in Developing Countries: Unlocking the Potential of Distributed Recycled Water Systems to Reduce the Overall Energy Intensity for Urban Water Services
… is a significant operational expense for most water utilities, particularly in developing countries. The current linear approach to water management will further increase the overall energy intensity (kWh/kL) for water services as rapidly growing cities move towards remote sources of water, …

Graywater research findings at the residential level
As populations continue to grow and water supply sources become more stressed, innovative means for reducing our reliance on municipal water are becoming more prevalent. Graywater reuse is one water conservation practice which has the potential of reducing household water demands by 30% indoors and …

The Binding of the Micronutrient Transition Metals to the Alkylation Products of Chemical Warfare Agent, Sulfur Mustard, and Thiols, Potentially Giving New Understanding to Physiological Effects of Exposure and Increased Toxicity
… an octahedral complex with two TTDPA ligands, one water molecule and another Cu2+ ion. Even with the addition of the copper bound carboxylate, the copper – tridentate ligand interaction was enough to give sufficient binding and stability. Although these two structures existed in all ratios of …
