As Texas' rivers run dry and lakes fall to record low levels, part of the fight over water supplies is moving underground.
"Our nose is able to detect thiols at extremely low levels, parts per billion," Dr. Wood said.
This is because hormones in our bodies are active at very low levels, parts-per-billion or lower.
An attribute with a larger difference between its lowest level part-worth and its highest level part-worth is considered to have a greater relative importance in the patient's choice [4, 21].
One of my first consulting projects as a student involved fixing an IBM 370 Assembler program that used registers, that is, a low-level part of the hardware architecture, as a convenient form of storage for a variable.
A low-level part of the visual system just one step removed from the retina buzzes while a monkey maintains a visual memory--a power once ascribed only to more sophisticated parts of the brain.
The typical employment pattern for women in Japan is age-related, following an M curve: it peaks by 24, drops sharply, then spikes again in the early 50's (when former housewives take low-level part-time jobs) before falling off for good at 55.
Instead, from a bunch of low-level parts that interact only with other nearby parts, complex global behaviors emerge that, for example, can simulate physical systems such as fluid flow, optics, population dynamics in nature, voting behaviors, and perhaps even the very nature of space-time.
Five studies were carried out around hazardous waste sites in California in which the main route of exposure was to low-level parts per billion concentrations of either gaseous emissions or airborne dust particles.
Results showed that Osterix was at an extremely low level in part of cells of the flattened cell zone and the upper hypertrophic cell zone in condylar cartilage and angular cartilage, independent on Runx2.
