Normal concentration, a measure of concentration for a chemical in a solution.

He's shorter and works with a frown; it seems to take twice his normal concentration to finish some tasks.

Some interesting experiments have been done looking at plants grown in a chamber with a higher than normal concentration of CO2 gas.

Normal concentration in healthy human serum is usually lower than 10 mg/L, slightly increasing with aging.

It meant thinking well beyond the powers of normal concentration and then daring your courage to follow your thoughts.

The normal concentrations of stars in the Galaxy faded and looked dark beside the brilliance of the star cluster.

Higher than normal concentrations of oxygen lead to increased levels of reactive oxygen species.

The normal concentration of potassium in the body is regulated by the kidneys through the excretion of urine.

It is found naturally in the human body but it is not known whether it has an important physiological role at normal concentrations.

Interference from calcium, magnesium, or lithium, on the other hand, is weak enough that their presence in normal concentrations is also usually not a problem.

Platelet activating factor decreases with prednisolone therapy and might return to normal concentrations in quiescent patients.

The molar (amount) concentration has variants such as normal concentration and osmotic concentration.

At more normal concentrations, it passes via what is believed to be a calcium/sodium-dependent, phosphorylation-related, active transporter into the cell.

In the fasted state, cortisol stimulates several processes that collectively serve to increase and maintain normal concentrations of glucose in blood.

T cell dysfunction in the presence of relatively normal concentrations of gammaglobulin is one way of defining Nezelof syndrome.

The normal concentration of CO2 in air of course varies but is of the order of only tenths of a percent or less.

According to the United Nations the normal concentration of uranium in soil ranges between 300 μg kg and 11.7 mg kg.

Vast efforts were therefore made to sep- arate the two isotopes and prepare uranium with a higher than normal concentration of uranium-235 ("enriched uranium").

Under normal blood glucose levels, this interchange will cause no problems, as aldose reductase has a low affinity for glucose at normal concentrations.

Tobacco smoking (through carbon monoxide inhalation) raises the blood levels of COHb by a factor of several times from its normal concentrations.

Levels of ClO climbed to five times their normal concentration between latitudes 40 and 60 degrees north between December 1988 and February 1989.

They then remove the cross-links, repair any damaged molecules an structures, and restore normal concentrations of salts, blood sugar, ATP, and so forth.

Despite its short lifetime, some radon gas from natural sources can accumulate to far higher than normal concentrations in buildings, especially in confined areas such as attics and basements.

In previous photographs, including one taken by Dr. Edwin P. Hubble, for whom the telescope is named, the galaxy appeared to be typical of normal concentrations of stars.

Mr. LaFace says the 200,000-plus jobs added over the last decade include a higher than normal concentration of manufacturing positions, particularly in food processing, one of the state's biggest industries.
