Without modification, other forms of inorganic nitrogen, for instance nitrate, are not included in this measurement. Using an empirical relation between Kjeldahl nitrogen and protein, it is an important method for indirectly quantifying protein content of a sample. This method was developed by Johan Kjeldahl in 1883. [1] [2]
The cracking of joints, especially knuckles, was long believed to lead to arthritis and other joint problems. However, this has been debunked . The cracking mechanism and the resulting sound is caused by dissolved gas (nitrogen gas) cavitation bubbles suddenly collapsing inside the joints. This happens when the joint cavity is stretched beyond ...

Areas of research published in the journal include modeling; solution techniques and applications of computational methods in areas including liquid and gas dynamics, solid and structural mechanics, biomechanics); variational formulations and numerical algorithms related to implementation of the finite and boundary element methods; finite difference and finite volume methods and other ...
That creates space, which is then filled by the joints’ lubricative synovial fluid (made up of oxygen, nitrogen and carbon dioxide), adds Liza Egbogah BS.c., D.C., D.O.M.P., a posture expert ...
The measured signal from the thermal conductivity detector for the unknown sample can then be converted into a nitrogen content. As with the Kjeldahl method, conversion of the concentration of nitrogen in a sample to the crude protein content is performed using conversion factors which depend on the particular amino acid sequence of the ...
The bones in your neck are connected by small joints, called facet joints, that help you move your head, says Sandra Miller, P.T., physical therapist with Briotix. “Like any other joint in your ...
