alkaline pH

They form at a neutral to alkaline pH of the urine.

This was important as alkaline pH values can by themselves increase chemiluminescence.

Several methods are used to lower the alkaline pH to an acceptable level to decrease the impact on the environment.

They are a relatively hardy fish whom prefer weakly alkaline pH conditions.

Enterococci survive very harsh environments including extreme alkaline pH (9.6) and salt concentrations.

Its activity is also more rapid at an alkaline pH, which suggests that the unprotonated form may be more active.

Alkaline pH favors formation of carbonate and phosphate calculi.

But they also have a high calcium carbonate content and an alkaline pH, which limits their productivity in some crops (for example, blueberries).

The same volume of denaturation solution (alkaline pH) was added to the tube and incubated for 10 min at room temperature.

An alkaline pH causes more nicotine to be absorbed, especially the free, unprotonated form, but is irritating to the mucosa.

However, deep sandy loam to loamy soils with neutral or slightly alkaline pH are considered optimum for growth.

Covering steel with concrete can provide some protection to steel because of the alkaline pH environment at the steel-concrete interface.

S. griseus and its related strains have recently been shown to be alkaliphilic, i.e., they grow best at alkaline pH values.

The Fu has a pebbled bottom, clean water, rich vegetation and an alkaline pH, conditions that are ideal for trout.

In the presence of divalent cations (Mg, Ca), or at alkaline pH the activation takes much longer.

Control of motilin secretion is largely unknown, although some studies suggest that an alkaline pH in the duodenum stimulates its release.

Like all Mbuna these fish require very pure, well aerated water with a moderate to high level of hardness and a moderately alkaline pH (7.5-8.5).

The plant is also used as animal feed and organic fertilizer although there is controversy stemming from the high alkaline pH value of the fertilizer.
