Hydrogen breath tests are based on the fact that there is no source for hydrogen gas in humans other than bacterial metabolism of carbohydrates. [4] Even though the test is normally known as a "hydrogen" breath test, some physicians may also test for methane in addition to hydrogen. Many studies have shown that some patients (approximately 35% ...
Archaeological site of Cerro del Villar. The first colonial settlement in the area, dating from around 770 BC, was made by seafaring Phoenicians from Tyre, on an islet in the estuary of the River Guadalhorce at Cerro del Villar (the coastline of Málaga has changed considerably since that time, as river silting and changes in river levels have filled the ancient estuary and moved the site inland).

In 1890, Rydberg proposed on a formula describing the relation between the wavelengths in spectral lines of alkali metals. [2]: v1:376 He noticed that lines came in series and he found that he could simplify his calculations using the wavenumber (the number of waves occupying the unit length, equal to 1/λ, the inverse of the wavelength) as his unit of measurement.
[5] [6] Sørensen described a way of measuring pH using potential differences, and it represents the negative power of 10 in the concentration of hydrogen ions. The letter p could stand for the French puissance, German Potenz, or Danish potens , all meaning "power", or it could mean "potential".
