In two previous papers, the writer described the effects of acids, alkalies, and salts,’ and the effects of combinations of salts with acids and alkalies* on the precipitation of gelatin by alcohol. In a preliminary paper,” a brief account was given of antagonism observed between different salts in gelatin, these results being of particular interest to the biologist from the point of view of th...

This study reports the chemical composition of particles present along Greenland’s North Greenland Eemian Ice Drilling (NEEM) ice core, back to 110,000 years before present. Insoluble and soluble particles larger than 0.45μm were extracted from the ice core by ice sublimation, and their chemical composition was analyzed using scanning electron microscope and energy dispersive X-ray spectroscopy...

Evidence for deliquescence of perchlorate salts has been discovered in the Martian polar region while possible brine flows have been observed in the equatorial region. This appears to contradict the idea that bulk deliquescence is too slow to occur during the short periods of the Martian diurnal cycle during which conditions are favorable for it. We conduct laboratory experiments to study the f...

The byproducts of flue gas desulfurization (BFGD) are a useful external source of Ca(2+) for the reclamation of sodic soils because they are comparatively cheap, generally available and have high gypsum content. The ion solution composition of sodic soils also plays an important role in the reclamation process. The effect of BFGD on the soluble salts composition and chemical properties of sodic...

THE RESULTS OF THE STUDY OF THE INHIBITING EFFECT OF NEUTRAL SALTS UPON THE CLOTTING TENDENCY OF FIBRINOGEN BY THROMBIN MAY BE SUMMARISED AS FOLLOWS: Salts like NaCl and KCl inhibit only weakly. Salts of the same cation (K(*)) with monovalent anions of different ionic radius are the more active the larger the anion (Cl',Br',I'). Salts of the same cation with anions of different valency are the ...

Work reported in recent years from this laboratory has outlined the general features of poisoning in animals given diand trialkyl tin salts (Stoner, Barnes, and Duff, 1955). More detailed accounts of the cerebral oedema produced by triethyl tin in rats (Magee, Stoner, and Barnes, 1957) and the bile duct and liver lesions produced by dibutyl tin salts in rats and mice have also been prepared (Ma...
