Land Clearing Effect on the Variability of some Soil Properties of an Alfisol in South-Western Nigeria [PDF]
Tropicultura, 2000 The variability of some soil properties of a mechanically cleared plot was compared with an adjacent plot under natural vegetation in an Alfisol of South-western Nigeria. The soil properties studied were pH, total N, available P, exchangeable acidity Ca,

Cation Exchange Properties of Alginic Acid
Experimental Biology and Medicine, 1952 SummaryAlginic acid possesses sodium and potassium ion exchange properties which compare favorably with those of a carboxylic type cationic exchange resin. Under in vitro conditions alginic acid at pH 7.6 adsorbs 4.2 meq Na+ per g. The total cation adsorption from solutions containing K+ and Na+ is also 4.2 meq/g and the ratio of Na:K combined ...

The Exchangeability of Amino Acids in Proteins [PDF]
Genetics, 2005 Abstract The comparative analysis of protein sequences depends crucially on measures of amino acid similarity or distance. Many such measures exist, yet it is not known how well these measures reflect the operational exchangeability of amino acids in proteins, since most are derived by methods that confound a variety of effects ...
