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.

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 new method of retting flax recently developed to suit the United Kingdom climate has allowed the reintroduction of flax growing to this country. The weed killer glyphosate is sprayed on the crop which then rets before harvesting six weeks later. The acute bronchoconstrictor responses of 11 normal subjects to dust from dew retted and from pre-harvest retted flaxes were compared in a double bli...

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...

This paper examines lunisolar calendar anomalies in the Taiwan stock market, particularly the solar term effect. Using the Taiwan Stock Exchange Capitalization Weighted Stock Index (TAIEX), the significance of the solar term effect was tested. Statistical results showed that the lowest and the highest average stock returns are observed on Cold Dew and White Dew, respectively. Additionally, we f...
