In general these metastases can be found by means of x-ray examination as soon as by an isotope tracer. Other tests and studies could be discussed, but the foregoing, at present, have been found ...

Stable isotopes can also be used as tracers, which are deliberately added to a system that is to be studied, such as in agriculture or nutrition. For this purpose, they must be separated using highly ...

It also promotes the use of isotope techniques for assessing water resources and ... In the field of radioisotope applications, the Section uses, among other tracers, the naturally-occurring ...

Using radioactive isotope systems to determine the age and origins of minerals and rocks, primarily as tracers of magmatic processes and the evolution of the earth. Organic molecules in natural waters ...

More precisely, they measured the nitrogen isotope ratio of the tiny amount of organic matter locked in the coral skeleton as a novel tracer of oxygen concentration in the ocean. In oxygen-poor ...

The team also labeled P2045 with technetium-99, a standard metal isotope tracer for medical applications, to generate a companion imaging compound. Andarix has a codevelopment and ...

An isotope emits gamma rays that easily pass through the body to a detector outside the body, for example a ‘gamma camera’. In this way, the radioactive isotope can be followed as it flows ...
