Dew is one of the important moisture sources in many arid and semiarid regions. The knowledge origin dew under various climatic conditions still lacking. Isotopic variations can preserve information about formation mechanisms. Therefore, isotopic compositions precipitation (δ2H, δ18O, δ17O, d-excess, lc-excess 17O-excess) were investigated at three sites with different (i.e., Gobabeb extremely ...

Hydrocarbon liquid dropout can cause a number of problems in gas transmission lines, including increased pressure drop, reduced line capacity, and equipment problems such as compressor damage. To avoid liquid dropout, most current operating specifications for gas transmission lines require that the lines be operated above the hydrocarbon dew point (HDP) or cricondentherm hydrocarbon dew point (...

The Diagnostic Encyclopedia Workstation (DEW) is a computer system that provides completely integrated pictorial and textual information as reference knowledge in the field of ovarian pathology. The textual component comprises information per diagnosis such as descriptions of macroscopic and microscopic images, clinical signs, and prognosis. In addition, the system offers lists of differential ...

Root growth of Cucumis and Avena seedlings is inhibited by volatile materials produced by leaves of Salvia leucophylla, S. apiana, and Artemisia californica. The toxic substance may be deposited when dew condenses on affected seedlings in the field.

Carbon steel AISI 1020 was exposed to environmental conditions along a transect of the Atacama Desert gather experimental evidence identify local atmospheric mechanism that triggers corrosion through buildup water layer formation on metal surface in addition evolution. Coupons initially left selected sites were periodically collected determine weight loss and attributes by scanning electron mic...

Evaporation of water from the skin is an important mechanism in thermal homeostasis. Resistance hygrometry, in which the water vapor pressure gradient above the skin surface is calculated, has been the measurement method of choice in the majority of pediatric investigations. However, resistance hygrometry is influenced by changes in ambient conditions such as relative humidity, surface temperat...

This study presents experimental and theoretical results of winter dew harvest in México City in terms of condensation rate. A simplified theoretical model based on a steady-state energy balance on a radiator-condenser was fitted, as a function of the ambient temperature, the relative humidity and the wind velocity. A glass sheet and aluminum sheet white-painted were used as samples over the ou...

Dryland ecosystems cover 40% of the total land surface on Earth and are defined broadly as zones where precipitation is considerably less than the potential evapotranspiration. Nonrainfall waters (for example, fog and dew) are the least-studied and least-characterized components of the hydrological cycle, although they supply critical amounts of water for dryland ecosystems. The sources of nonr...

A scheme for large-scale dew collection as a source of fresh water supply is outlined in the present paper. The scheme envisages bringing cold seawater (5C) from about 500 meters depth and about 5 km from the shore, in four, 1.22 m diameter plastic pipes. It then passes through an onshore heat exchanger field with an area of 1.29 X 10 m (1.39 X 10 ft) where it condenses 643 m of dew over the 24...
