Water content of chlorophyll hydrate

Analytical Biochemistry, 1981
Abstract Thermogravimetry shows that polycrystalline chlorophyll a is a chlorophyll dihydrate. Neither thermogravimetry nor differential thermal analysis indicates the existence of a stable chl a monohydrate. Moreover it is found that larger amounts of water-free chlorophyll a (>50 mg) cannot be prepared by application of vacuum and heat in a ...

Placental water content and distribution

International Journal of Gynecology & Obstetrics, 1994
The percentage of total placental water (%H2O(T)), maternal (%MBV) and fetal (%FBV) blood volumes, non-vascular extracellular (%EW) and intracellular (%IW) water, and villous histology were studied in placentas from 12 normal term pregnancies after a normal vaginal delivery, 19 caesarean sections at term after a normal pregnancy and history of a ...

Thorium Content of Ocean Water

Science, 1958
Two samples of ocean water from the Pacific, one collected at the surface near the coast outside San Diego Bay in the summer of 1956 and the other taken at a depth of 3500 m from longitude 124 d 41.0' W, latitude 33 d 54.5' N on March 25, 1957, were analyzed for total thorium alpha activity.

Sodium Content of Water-Softened Water

JAMA: The Journal of the American Medical Association, 1974
To the Editor.— Physicians are ever alert to problems of excess salt ingestion in patients with congestive heart failure. Sodium chloride is used to regenerate the synthetic ion-exchange resin in home water-softeners. The question often arises whether the sodium chloride so used can lead to a high sodium content in the water. Separate analysis of such

Key soil water contents

2004
Publisher Summary This chapter studies critical components of a physics-based approach to define several characteristic points on the water retention curve. The idea is to find segments of the water retention curve at which the forces causing water retention have distinctly different physical natures and wet soil has distinctly different rheological ...
