Shadow of dew drops for piano trio
Shadow of Dew Drops for violin, violoncello and piano was inspired by a poetry of the Song Dynasty (960-1279) "Xiao Chi - A little Pond" written by the famous poet Yang Wanli (1127-1206). This poetry depicts: the silent mouth of a spring "cherishes" the little streamlet and lets it flow quietly …

Mineralogy and Geochemistry of the Dumper Dew Pegmatite, Oxford County, Maine
The Dumper Dew is a newly discovered pegmatite located on the eastfacing slope of Uncle Tom Mountain in Oxford County, Maine. It is a geochemically evolved LCT-type pegmatite petrogenetically linked to the middle Paleozoic Sebago batholith. Shallow emplacement of the Dumper Dew is evidenced by …

A Study of Dew Harvesting and Freezing Performance of Non-Wetting Surfaces
… the limited amount of time available to collect dew and fog than traditional surfaces. However, existing studies focus on short durations with scant information available on the longer-term performance or durability of the materials in application environments. To address this knowledge gap, dew …

Comparison and Simulation of a Water Distribution Network in EPANET and a New Generic Graph Trace Analysis Based Model
… compare the Distributed Engineering Workstation (DEW) and EPANET models. These two models are fundamentally different in the approaches taken to simulate hydraulic systems. To better understand the calculations behind each models' hydraulic simulation, three solution methods were evaluated and …

Selective oxidation and segregation in commercial steels and model alloys : (tools for improving the surface wettability by liquid Zn during hot dip galvanizing
… during annealing in 5% H2/N2 at 820°C at dew points -60, -30 and 0°C on HSS (DP 500, Ti-IF and TiNb-IF), and preoxidation in air at 700°C with subsequent annealing in 5% H2/N2 at dew point -30°C on model alloys (Fe-Al, Fe-Si and Fe-Mn).External oxidation of Al and Mn is observed at dew …

Limiting Activity Coefficients for Aqueous Solutions
… developed based on measuring the change in the dew point temperature of a solvent with the dilute addition of a solute. This dew point method was used to measure $\gamma\sp\infty$ for three solutes in water over a range of temperatures. The low $\gamma\sp\infty$ values for these solutes indicate …

Advanced Faraday cage measurements of charge, short-circuit current and open-circuit voltage
… the center electrode of the electrode chamber. Dew point analysis is performed to show that for water to condense on metallic surfaces, it is not necessary to reach the dew point. The calculated dew point temperature is lower than the temperature at which the water condenses upon the electrode …

Managing bacterial wilt, caused by Erwinia tracheiphila, on muskmelon with early control of striped cucumber beetle ( Acalymma vittatum (F)), and through varietal selection
… Without row covers, cultivars ‘Diplomat’, ‘Dream Dew’ and ‘RML 9818’ attracted higher numbers of SCBs than most other cultivars at one location each. ‘Dream Dew’ (at all locations) and ‘RML 9818’ (at two locations) had significantly higher percentages of BW than the least susceptible cultivars. …

High temperature corrosion in gas turbines : thermodynamic modelling and experimental results
… surface temperature of a material is below the dew point of a corrosive salt and condensation can take place. The dew point of different salts has been calculated in the thermodynamic modelling, and the impurities S, Na, K and Cl were added in typical amounts for low-impurity fuels. This study …

Kytoon observations of the Lake Mead boundary layer
… Mead boundary layer was characterized by higher dew points than the surrounding Mojave Desert air mass. In addition, the mountainous terrain around the lake represents a potential influence for isolating the Lake Mead boundary layer, preventing its migration to other locales, and allowing the …

Development of adsorption-based atmospheric water harvesting and thermal energy storage technologies
… operation of competing technologies, such as dew-based atmospheric water generators (AWGs), is infeasible. Laboratory experiments and computational simulations were used to optimize the device based on this MOF to maximize water delivery capacity in arid climates. We subsequently tested an …
