Geochemical Techniques in Geothermal Development: an Update

The ultimate goal of geochemical studies of geothermal systems is to understand the physical-chemical processes responsible for their origin and evolution. The chemical composition of fluids (separated vapor and water), collected from fumaroles, hot springs and drilled wells at the Earth’s surface (25oC) is determined in the laboratory. Using the chemical geothermometers, conservation of mass, ...

Determination of serum estradiol levels by radiometric and chemiluminescent techniques.

The ability to precisely measure circulating levels of hormones is a foundation of modern endocrinology. For assisted reproductive technologies such as in vitro fertilization (IVF), accurate determination of circulating levels of estradiol are crucial for patient management, retrieval of fertilizable oocytes, and successful pregnancy outcome. For many years, circulating levels of estradiol were...

Radiometric and Photometric Concepts Based on Measurement Techniques

The value of the fundamental quality in radiometry, the watt, is presently realized by electrical substitution in which the temperature produced in a blackened material due to absorption of radiant energy is balanced against that produced by electrical energy whose current and voltage can accurately be measured. A new method to measure optical radiation is being explored by the National Bureau ...
