Stability of water-in-oil-in-water type globules
Chemical Engineering Science, 1996Abstract A method for producing a single water-in-oil-in-water (W/O/W) type globule is used to study its stability microscopically, by bringing the internal water droplets in contact with each other and with the external interface between water and oil.

A New Type of Water Dermatitis in Louisiana
Southern Medical Journal, 1960A number of causes of “creeping eruption” are known and recognized in the southern states. However, one indigenous to the Louisiana swamps, though spoken of in colloquial terms by the residents of the area, has not been recognized as an entity until now. The authors describe Strongyloides myopotami,

Types and Characteristics of Drinking Water for Hydration in the Elderly
Critical Reviews in Food Science and Nutrition, 2013The role of hydration in the maintenance of health is increasingly recognized. Hydration requirements vary for each person, depending on physical activity, environmental conditions, dietary patterns, alcohol intake, health problems, and age. Elderly individuals have higher risk of developing dehydration than adults.

The Quality of Potable Water Types in Jordan
Environmental Monitoring and Assessment, 2006Four different potable water types: tap water, desalinated water in private plants, homes filtrated and sealed bottled water were collected from four provinces in Jordan and analyzed for various physiochemical parameters and trace metals content. The results showed that quality of potable water varied depending on many factors such as: water quality at

Types and Quantities of Water Demand
1994Historically, water demand has been distinguished only according to broad usage, for instance, use by the urban, industrial, agricultural, recreational and environmental sectors. In our view, the exclusive reliance on the traditional approach of classification of water demand is both inadequate and in some respects misleading.

Tetrahedron Letters, 1994
Abstract The presence of water is determining for the efficiency of quaternary ammonium salt (QX) in palladium-catalysed vinylation of organic halides using an alkali metal carbonate as the base, whether QX is a chloride, a bromide or a hydrogensulfate. The [Pd/M 2 CO 3 /QX] catalyst system can even be used for performing the reactions in neat water,

Types and Quantities of Water Supply
1994A water-supply system may be defined as a group of water-production facilities, such as reservoirs, wells, and treatment plants, and transmission facilities, such as pumping stations and pipelines to supply each consumer. The system may obtain water from various sources each requiring a particular production process, treatment, purification ...

Mineralogical Magazine, 1969
SummarySurface areas of ‘amorphous’-type opals measured by nitrogen-absorption techniques were not consistent either with the surface area of the spheres of about 2000 Å diameter observable by electron microscopy or with the thermal dehydration data. This apparent inconsistency can be explained in terms of a smaller particulate structure of the order ...

Chironomids and regional water types
Netherlands Journal of Aquatic Ecology, 1992The distribution pattern of 115 chironomid taxa at 664 sites, distributed over all kinds of water, was analyzed and related to 42 water types, based on the complete macrofauna composition. The distinction of chironomid groups was not useful to recognize water types.
