A microplate apparatus having a bottom plate defining a plurality of very small microwells (for example, each having a volume of 0.02 or less) for containing sample material and a top plate defining a plurality of domes, each of which housing a sensors for measuring biological parameters, such as cellular oxygen consumption, pH changes, calcium uptake, and metabolic reduction of fluorescent dyes. The top and bottom plates may be composed of quartz. The microplate assembly may be fabricated using a method involving applying an etching solution to each of the top and bottom plates to create the domes and microwells. Additionally, etching solution may be applied to the bottom plate to create a raised lip region around each of the microwells. The etched-away areas surrounding the lip regions facilitate the changing of microwell solution without disrupting the samples.

Dietary fiber is known to have the effect of inhibiting the absorption of calcium from the intestinal tract. Thus, in order to effectively absorb calcium into the body, it is preferable to not consume calcium and dietary fiber at the same time; however, doing so can be a hassle for consumers attempting to effectively supplement these minerals and components. In the present invention, refined calcium salt having an average particle size of no more than 50 μm, wherein primary particles of calcium salt that are flat with an average length of no more than 2 μm in the planar direction have aggregated to form secondary particles having an average particle size of no more than 50 μm, is capable of suppressing the absorption inhibiting action of dietary fiber consumed at the same time and enhances the absorption rate of calcium to the body. As a result, it is possible to provide consumers with a food product that includes both calcium and dietary fiber and enables a high calcium absorption rate, and thus it is possible to improve the convenience for consumers.

The invention relates to a chemical metallurgy comprehensive utilization method for phosphogypsum and nepheline ore joint development. The method is characterized in that sulfate radical in phosphogypsum is grafted onto aluminum and potassium in nepheline ore through a special double-decomposition reaction, thereby obtaining activated aluminum oxide and a potassium compound fertilizer through solution leaching, separation and conversion; and calcium in the phosphogypsum is combined with the silicate radical in the nepheline ore to obtain calcium silicate having wide application ranges and high values. The specific process comprises the following steps: grinding the phosphogypsum and the nepheline ore, conducting uniform mixing and roasting, performing pressure leaching and boiling on the roasted materials with water used as a leaching agent for aluminum and potassium leaching, and performing solid-liquid separation, wherein the solid phase is washed to obtain the calcium silicate product, and the solution phase is a leached potassium sulfate and aluminum sulfate solution; and treating the leached solution with ammonium hydrogen carbonate for aluminum precipitation and potassium separation, wherein the solid phase is aluminum carbonate hydroxide, and is dried and the dried material is calcined to obtain the activated aluminum oxide product, and the liquid phase is potassium sulfate and ammonium sulfate mixed solution, and is concentrated, then the concentrated material is absorbed with a phosphorus material (powdered rock phosphate, calcium superphosphate or calcium triple superphosphate) and ageing, pile turning and drying are conducted to obtain a nitrogen / phosphorus / potassium compound fertilizer.

Dietary fiber is known to have the effect of inhibiting the absorption of calcium from the intestinal tract. Thus, in order to effectively absorb calcium into the body, it is preferable to not consumecalcium and dietary fiber at the same time; however, doing so can be a hassle for consumers attempting to effectively supplement these minerals and components. In the present invention, refined calcium salt having an average particle size of no more than 50 [mu]m, wherein primary particles of calcium salt that are flat with an average length of no more than 2 [mu]m in the planar direction have aggregated to form secondary particles having an average particle size of no more than 50 [mu]m, is capable of suppressing the absorption inhibiting action of dietary fiber consumed at the same time andenhances the absorption rate of calcium to the body. As a result, it is possible to provide consumers with a food product that includes both calcium and dietary fiber and enables a high calcium absorption rate, and thus it is possible to improve the convenience for consumers.
