Industrial Bio-Test Laboratories (IBT Labs) was an American industrial product safety testing laboratory. [1] [2] [3] IBT conducted significant quantities of research for pharmaceutical companies, chemical manufacturers and other industrial clients; at its height during the 1950s, 1960s, and 1970s, IBT operated the largest facility of its kind and performed more than one-third of all ...
Riverbank Acoustical Laboratories (RAL), (often referred to as Riverbank or Riverbank Labs), is a NVLAP accredited acoustical testing agency founded by George Fabyan in 1913. [1] [independent source needed] The testing service remains a highly respected source of independent acoustical materials testing.

Mathews Avenue in Urbana, Illinois on the campus of the University of Illinois at Urbana–Champaign, houses the university's Department of Civil and Environmental Engineering.
Isobars are atoms of different chemical elements that have the same number of nucleons. Correspondingly, isobars differ in atomic number (or number of protons ) but have the same mass number . An example of a series of isobars is 40 S , 40 Cl , 40 Ar , 40 K , and 40 Ca .
The Wyle Labs facility in Norco, California was established in 1957 for military testing, working with aerospace firms and on nuclear research programs. The facility first came under scrutiny in 1999 and the early 2000s for groundwater contamination to the site and surrounding areas as a result of mishandling and improper disposal of chemicals.
Analysis of sound and acoustics plays a role in such engineering tasks as product design, production test, machine performance, and process control. For instance, product design can require modification of sound level or noise for compliance with standards from ANSI, IEC, and ISO. The work might also involve design fine-tuning to meet market ...
10 Be, 26 Al, and 36 Cl are used for surface exposure dating in geology. [10] 3 H, 14 C, 36 Cl, and 129 I are used as hydrological tracers. Accelerator mass spectrometry is widely used in biomedical research. [11] [12] [13] In particular, 41 Ca has been used to measure bone resorption in postmenopausal women. [citation needed]
Beta-decay stable isobars are the set of nuclides which cannot undergo beta decay, that is, the transformation of a neutron to a proton or a proton to a neutron within the nucleus. A subset of these nuclides are also stable with regards to double beta decay or theoretically higher simultaneous beta decay, as they have the lowest energy of all ...
