Improvement of phosphorus circulation in the soil is necessary to enhance phosphorus availability to plants. Phosphorus circulation activity is an index of soil's ability to supply soluble phosphorus from organic phosphorus in the soil solution. To understand the relationship among phosphorus circulation activity; bacterial biomass; pH; and Fe, Al, and Ca concentrations (described as mineral co...

Phospholipid bilayer membranes were bathed in a decimolar solution of monovalent ions, and the conductance produced by neutral carriers of these monovalent cations and anions was used to assess the electric potential at the surface of the membrane. When the bilayers were formed from a neutral lipid, phosphatidylethanolamine, the addition of alkaline earth cations produced no detectable surface ...

Abstract This paper describes a method for measuring the longitudinal wake potential of the Cornell Electron-Positron Storage Ring (CESR). The longitudinal wake potential was determined by measuring the time delay between successive bunches as a function of current. The slope of the wake potential was determined by the changes in the bunch length as a function of bunch current. A theoretical de...

Abstract Leaching titaniferous magnetite concentrate with alkali solution of high concentration under temperature and pressure was utilized to improve the grade iron in TiO 2 titanium tailings. The use contained 12.67% 54.01% Fe. thermodynamics possible reactions kinetics leaching process were analyzed. It found that decomposing FeTiO 3 NaOH aqueous could be carried out spontaneously reaction r...

Two ruminally cannulated cows were fed a diet containing 65% alfalfa haylage and 35% concentrate every 12 h. During two collection periods, whole ruminal contents were sampled before feeding, when feed not eaten was removed (1 h after initiation of feeding) and 1, 2, 3, 4, 6, 8, 10 and 12 h after removal. At each sampling, fluid-associated microorganisms were obtained by straining whole ruminal...
