摘要： On a slab-like board formed of a transparent material is closely attached a wedge-shaped transparent cover member provided with a recess in a central inner portion, thereby to form a clearance. The height of the clearance between the recess and the board is configured to decrease continuously or in steps. When an immunological active substance such as a monoclonal antibody is caused to sensitize carrier particles F, and a reagent having the carrier particles F dispersed into a liquid medium mainly composed of the water is mixed with a specimen, the reaction will occur in which the flocculate is formed from plural carrier particles. When this reaction liquid is poured into the clearance through the opening, the reaction liquid penetrates in the direction having a narrower vertical spacing due to surface tension. A single carrier particle unflocculated can move deep within the recess because it is small in diameter, but the flocculate G is trapped on its way and can not move because of its size.

摘要： A novel method of determining the portion of a given dairy cow feedstuff which is attributable to non-structural carbohydrates is disclosed. The method includes the steps of analytically determining the percentages of crude protein, lipid and ash in the dry matter concentration of a first feed sample, and in the neutral detergent fiber which has been separated from the soluble matter of a second sample of the same feed, and subtracting the amounts of crude protein, lipid and ash in the neutral detergent fiber from the respective amounts of the same substances in the original sample. The three difference figures are totaled and subtracted from the percentage of the second sample represented by neutral detergent solubles, i.e., 100 minus neutral detergent fiber, thereby providing an accurate indication of the percentage of non-structural carbohydrate in the feedstuff. The method is applied to both forages and grains, and is employed in the formulation of dairy cow rations wherein ration is adjusted to optimize milk production, the preferred percentage being from about 30% to about 45% depending on forage type.

摘要： Systems and methods for minimizing extraneous forces and calculating corrected weights of samples based on buoyancy factors for a thermogravimetric analyzer (TGA). The TGA includes a balance chamber and a furnace configured to heat a sample. A null balance is provided in the balance chamber and is used to measure the sample weight change during heating. The furnace includes a cylinder open at the top to receive a sample. The bottom of the cylinder is closed except for a small hole that allows a thermocouple to pass through. An infrared heat source may be provided to heat the cylinder. The balance chamber can be thermally isolated from the furnace using an actively cooled plate and a system of heat shields disposed between the furnace and balance chamber. A thermocouple disk is further provided to limit gas flow in the furnace and increase reliability of sample weight measurements.

摘要： A method for determining the susceptibility of a sample of Zircaloy alloy to nodular corrosion. A specimen of such Zircaloy sample is annealed at a temperature within a temperature range bounded at its upper limit by the temperature T.sub.c being the temperature at equilibrium wherein sufficient solute would exist in the (.alpha.-matrix of the particular zircaloy to resist nodular corrosion, and bounded by a lower temperature, such temperature being the temperature of the (.alpha.+precipitate)/(.alpha.+.beta.+precipitate) transus for the particular Zircaloy sample. For Zircaloy-2, such temperature range is from approximately 825.degree. C. to 841.degree. C. The specimen is maintained at such selected temperature within such temperature range for a measured period, and subsequently exposed to steam at a fixed temperature and pressure for a fixed time. If nodular corrosion does not appear the above steps are repeated, but on each different specimen increasing the measured time period until a last measured time period is obtained when nodular corrosion first appears on a specimen. The length of the last measured time period is used as an indicator of the sample's resistance to nodular corrosion, and thus conversely its susceptibility to nodular corrosion.
