In the method of determining need for human estrogen or estradiol level change, the steps include determining local acidity proximate a moist wall surface of the vagina, as differing from desired threshold level, and administering sufficient estrogen or estradiol to result in change in acidity toward such level.

In the method of determining need for human estrogen replacement therapy or estrogen or estradiol dose change, the steps include determining local acidity proximate a moist wall surface of the vagina, as differing from desired threshold level (pH 4.5), and administering sufficient estrogen or estradiol to result in change in acidity toward such level.

A method and system for determining the geographical distance between a first object and a second object based on the use of a vertical-horizontal coordinate system. First identification information for the first object is provided, and a first set of vertical-horizontal coordinates corresponding to the first object is determined. Similarly, second identification information for the second object is provided, and a second set of vertical-horizontal coordinates corresponding to the second object ...

A device and method for determining values and/or generating signals, which can be used for closed-loop or open-loop controlling of the driving behavior of a vehicle equipped with a sensor system that detects wheel contact forces, includes determining the vehicle mass via the wheel contact forces that are detected, and further includes at least one of determining shifts in the wheel contact forces, and determining the required drive torque.

The optical detection of the concentration of a specific substance in a liquid or a gas by the utilization of the quenching of a phosphor by the specific substance or a substance derived from the specific substance is attained with high accuracy by a method and apparatus which comprises causing the system of determination to induce the presence of a first phosphor (A) quenchable by the specific substance or a substance derived from the specific substance and a second phosphor (B) substantially u...

The delay between a first signal and a second signal is evaluated by deriving from the first signal substantially aperiodic events, possibly by using a zero-crossing detector on a random signal, and using these events to define respective segments of the second signal. The segments are combined, e.g., by averaging, to derive a waveform which includes a feature representing coincidences of parts of the second signal associated with the derived events. The delay is determined from the position wit...

Oil saturation in a reservoir is determined by injecting into the reservoir a displacing fluid that will displace oil and water toward an observation well forming a "stable" oil-water bank, and measuring the arrival time of the stable oil-water bank at the well--a substantial difference in the rate of bottom-hole pressure change is realized once the bank arrives at the observation well. From these data, the oil saturation is determined by the formula: S.sub.oi = f.sub.ob (1 - V.sub.i) + f.sub.oi...

A reagent for albumin determination comprising an aqueous solution of 0.1 - 0.2 grams of bromcresol green, 4 - 6 grams of sodium salt of EDTA and 4.5 - 6 ml. of polyoxyethylene fatty alcohol ether per liter of said solution buffered to pH 4 - 4.2.
