Controlled-release herbicide formulations have been shown to decrease the leaching potential of several herbicides under laboratory and Ðeld conditions. The utility and efficacy of these formulations may be improved by combining several herbicides and a fertilizer source in a single formulation. The objective of these studies was to develop granular alginate formulations that were composed of a...

BACKGROUND Prospective data on the relation of magnesium, potassium, and calcium intakes with stroke risk are inconsistent, and to our knowledge, the effect of a combined mineral diet score has not been examined. OBJECTIVE We examined associations between intakes of magnesium, potassium, and calcium and risk of incident stroke in 86,149 women in the Nurses' Health Study (NHS) I and 94,715 wom...

This study was conducted to evaluate the potential use of milk mineral (MM) as calcium source for production calcium-fortified yogurt. MM composed 83% minerals, 7.5% lactose, 3.3% protein, and < 1% fat. Calcium (Ca) content in about 46%; calcium: phosphorous ratio 1.28:1. The aqueous solubility Ca increased with decrease pH; at pH 4 5 98% 53%, respectively. Ca-fortified yogurt up 200 mg Ca/1...

The vast majority of carbonate minerals in modern marine sediments are biogenic, derived from the skeletal remains organisms living ocean. However, can also precipitate abiotically within sediments, and this mineral precipitation has been suggested as a third major, isotopically distinct, sink global carbon cycle, particularly important earlier Earth history. Here we present compilation pore fl...

Calcium is the only known component in the diet that may affect absorption of both nonheme and heme iron. However, the evidence for a calcium effect on iron absorption mainly comes from studies that did not isolate the effect of calcium from that of other dietary components, because it was detected in single-meal studies. Our objective was to establish potential effects of calcium on absorption...

The dissolution kinetics of pandermite and hydroboracite, present in an Iranian borate ore, in sulfuric acid has been comparatively studied. The effect of particle size, temperature, and acid concentration on their dissolution rate was investigated. Dissolution rates of both minerals increased by reducing the particle size and by raising the temperature. Although, an increase in the acid concen...

Liposome encapsulation technology has been used to entrap aqueous calcium salts within dipalmitoylphosphatidylcholine lipid vesicles, which were then used to form calcium phosphate minerals. The calcium encapsulation efficiency was found to depend upon a number of factors that included calcium salt concentration, vesicle size, lipid concentration, and method of vesicle preparation. Removal of u...
