The chemical environment
also remains one of the most underassessed service conditions.
And again, a new chemical environment
may present challenges to materials currently handling CFC coolants.
NICEATM has launched the Integrated Chemical Environment
(ICE), an online source of high-quality curated data and appropriate tools to support development and evaluation of new, revised, and alternative methods.
These cells give structural support and also help keep the chemical environment
of retinal neurons stable.
Bacteria are both consumers and producers and are the primary producers in chemosynthesis, so they will influence the chemical environment
, which allows other forms of life to establish.
Traditional point detectors do not always give a full and accurate picture of the chemical environment
However, the detection of glucose is possible in this research at pH value and chemical environment
To create a device that functions like a spleen and can change the chemical environment
of the blood cells is a key step forward and could change the lives of billions of sufferers for the better.
Our understanding is that M40/M42 and M50 mask canisters are good for six months in a non-chemical environment
and 24 hours in a chemical environment
Subsequent sections address different surface analysis methods for the characterization of reactive glass surfaces, infrared and raman spectroscopy and microscopy, and X-ray absorption spectroscopy for the characterization of the chemical environment
of metals in silicate glass materials, followed by studies of these methods to characterize archaeological glass fragments, historic museum pieces in glass, or other related materials, including Roman glass, European trade beads in Northeastern North America, Venetian soda glass, historic English lead glass, and Spanish monuments, and those from Bronze Age Italy, the Merovingian period in Western Europe, South and Southeast Asia, the Middle East, the Medieval period, and Versailles.
However, many researchers find it hard to imagine how such a molecular network could have formed spontaneously - with no precursors -from the chemical environment
of early Earth.
While chelation has been shown previously using single, chemically purified amino acids, such evidence has been elusive for more complex compounds, given the lack of methodologies to probe mineral bonding in such a varied chemical environment
that includes a broad spectrum of both essential and non-essential L-amino acids.
This discovery is a major step forward for stem cell therapies and personalized medicine; by exploiting this signaling system, scientists will be able to control the eventual fate of a stem cell by simply adjusting the chemical environment
of a cell.
In addition, the scientists used an X-ray technique that can distinguish the chemical environment
of the arsenic.
In utero and early postnatal exposure to environmental agents can influence childhood lung structure and function and may predispose individuals to chronic obstructive lung disease and other disorders later in life; the nutritional and endogenous chemical environment
can also affect development of the lung and result in altered function in the adult.
