Buffy-coat preparations of peripheral blood or aspirates from marrow, spleen, lymph nodes, or skin lesions should be spread on a slide to make a thin smear and stained with Leishman's or Giemsa's stain ( pH 7. 2 ) for 20 minutes.

Today the steep and narrow valleys are covered in a thin layer of soil, with a low pH, able to support only strong grasses, rushes, and heathers.

The bottom of a pH electrode balloons out into a round thin glass bulb.

Due to its citric acid content, orange juice is acidic, with a typical pH of around 3. 5 .< ref >

It also results in an increase in the pH of the juice which may be desirable for overly acidic grapes.

Because of the location of grape juice constituents in the berry ( water and acid are found primarily in the mesocarp or pulp, whereas tannins are found primarily in the exocarp, or skin, and seeds ), pressed juice or wine tends to be lower in acidity with a higher pH than the free-run juice.

Lemon juice is acidic with a pH of around 2. 3 on the pH scale.

It is filled to a depth of about with water that is heavily acidic ( 2. 5 pH level ), about the acidity of cola or lemon juice.

* Lemon juice and other acids lower the pH and remove the copper cofactor necessary for the responsible enzymes to function

* DDS ( Det Danske Sukkerfabrik-" The Danish Sugarfactory ") -- multistage process involving pre-liming where the pH of the juice is gradually increased to start precipitation of proteins, followed by addition of further lime and gas.

Bilimbi juice ( with a pH of about 4. 47 ) is made into a cooling beverage.

Furthermore, the juice of red cabbage can be used as a home-made pH indicator, turning red in acid and blue in basic solutions.

Red cabbage juice contains anthocyanin and can be used as a pH indicator.

Note that at ocean pH most of the CO < sub > 2 </ sub > produced in this reaction is immediately converted back into.

BookKeeper produced a pH of 9-10.

Usually, though not always, mash from a previous distillation is added to ensure a consistent pH across batches — and a mash produced in that manner is referred to as a sour mash.

Precipitation with low potential of hydrogen levels ( pH ), otherwise known as acid rain, is also a frequent risk produced by lightning.

The calibration process correlates the voltage produced by the probe ( approximately 0. 06 volts per pH unit ) with the pH scale.

Lactic acid is produced by the bacteria as a waste product, lowering the pH and coagulating and lowering the water-holding capacity of the meat.

Both L and D isomers of lactic acid are produced in the rumen ; these isomers are metabolized by different metabolic pathways, and activity of the principal enzyme involved in metabolism of the D isomer declines greatly with lower pH, tending to result in an increased ratio of D: L isomers as acidosis progresses.

Rather, the hyperventilation itself reduces the carbon dioxide concentration of the blood to below its normal level because one is expiring more carbon dioxide than what is being produced in the body, thereby raising the blood's pH value ( making it more alkaline ), initiating constriction of the blood vessels which supply the brain, and preventing the transport of oxygen and other molecules necessary for the function of the nervous system.

High levels can be produced by cells in response to hyperthermia, oxidative stress, and changes in pH.

Anolyte has an oxidation-reduction potential of + 600 to + 1200 mV and a typical pH range of 3. 5 –– 8. 5, but the most potent solution is produced at a controlled pH 5. 0 – 6. 3 where the predominant oxychlorine species is hypochlorous acid.

However, reported D (-) lactic acid can be produced when cultured at low pH.

Acidic water produced at active mines must be neutralized to achieve pH 6-9 before discharge from a mine site to a stream is permitted.

It was at that time known that milk fermented with lactic-acid bacteria inhibits the growth of proteolytic bacteria because of the low pH produced by the fermentation of lactose.

Regarding to fruit juices ( pH 3. 5 – 4. 5 ) commercially successful products have been produced, such as Gefilus ( Valio Ltd, Finland ), which contains Lactobacillus rhamnosus GG.

The tripeptide FPP ( fertilization promoting peptide ) produced by the male is essential for capacitation ( high levels of FPP prevent capacitation, the proper concentration occurs after ejaculation in the female reproductive tract where the concentration drops after mixing with vaginal secretions and / or becomes less active due to the pH of the vagina ).

As cells undergo metabolic processes, acid is produced and the pH decreases.

In the event of problems, waste products produced by dying cells or overgrowth of contaminants will cause a change in pH, leading to a change in indicator color.

In addition, the waste products produced by the mammalian cells themselves will slowly decrease the pH, gradually turning the solution orange and then yellow.

Under the alkaline conditions ( pH 7. 9 ) found in the sap of the epidermal cells, this combination produced a blue-green pigmentation ; the pH of the colorless inner floral tissue was found to be lower, at pH 5. 6.

Unless you want to make your wife a pool widow and to spend a great many of your leisure hours nursing your pool's pristine purity, its care and feeding -- from pH content to filtering and vacuuming -- is best left to a weekly or bi-monthly professional service.

Since pH is defined as the negative logarithm of the concentration of hydronium ions, acids thus have pHs of less than 7.

It is important to note that antibiotic therapy alone without surgical drainage of the abscess is seldom effective due to antibiotics often being unable to get into the abscess and their ineffectiveness at low pH levels.

At pH values greater than the pKa of the carboxylic acid group ( mean for the 20 common amino acids is about 2. 2, see the table of amino acid structures above ), the negative carboxylate ion predominates.

At pH values lower than the pKa of the α-ammonium group ( mean for the 20 common α-amino acids is about 9. 4 ), the nitrogen is predominantly protonated as a positively charged α-ammonium group.

The fully neutral form ( structure ( 1 ) on the right ) is a very minor species in aqueous solution throughout the pH range ( less than 1 part in 10 < sup > 7 </ sup >).

This pH is known as the isoelectric point pI, so pI

* Soluble AC ( sAC ) is not a transmembrane form and is not regulated by G proteins or forskolin, instead acts as a bicarbonate / pH sensor.

For example, the bioavailability of ketoconazole ( antifungal ) is reduced at high intragastric pH ( low acid content )

Soil with a pH value higher than 7. 3 is normally referred to as alkaline.

Usually, the application of KOH is needed to increase the pH to this range.

Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it possesses elevated levels of hydrogen ions ( low pH ).

Distilled water, once carbon dioxide is removed, has a neutral pH of 7.

An example of this effect is the low pH of rain which falls in Scandinavia.

This chart shows that not all fish, shellfish, or the insects that they eat can tolerate the same amount of acid ; for example, frogs can tolerate water that is more acidic ( i. e., has a lower pH ) than trout.

In cultivated areas, limestone may also be added to increase the ability of the soil to keep the pH stable, but this tactic is largely unusable in the case of wilderness lands.

Because the initial reaction is reversible, it is determined by pH.

To control bacterial growth, the vagina is normally slightly acidic with a pH of 3. 8 – 4. 2.

A pH greater than 4. 5 is considered alkaline and is suggestive of bacterial vaginosis.
