Tolerance unequal

The samples are irradiated in the reactor for a time between seconds and weeks, depending on the half-life of the radionuclide to be measured or the tolerable waiting time, whichever is shorter. Care must be taken to assure that the samples and standards receive equal exposure to neutrons, or that unequal doses be measured quantitatively by Irradiation of monitors. The flux in a reactor which operates at constant power can be stable to better than 1 from day to day, while that in a training reactor may vary greatly on a time scale of minutes. The very fact that the reactor core is a neutron source guarantees that there will be a spatial gradient in neutron intensity, which may amount to tens of percent or more across a large sample container (28). 

Secondly, the ministers urge that the desires and endeavours of the Independents for toleration are unreasonable and unequal in divers regards . 

Both the above factors promote unequal distribution of dlfiusible ions on either side of biological membranes which in turn would result in establishment of a pH difference and an oanotlc difference between the compartments. Minor pH changes are tolerable for most of the tissues but drastic pH changes may pose problems. Ihe body saves Itself finm the harmful influence of the latter with the help of its buffer tems. But sometimes maintenance of a drastic pH difference is a necessity, as is in the case of stomach. Gastric dilation cannot proceed if the pH is not maintained at a very low level. In this case, the gastric mucosal membrane i up to permit the hydrolysis reaction... 

Variations in tolerances and accumulations of tolerances can result in mismatched parts and cause high assembly stresses. Dissimilar materials will also cause additional stresses, if reactions to the assembly environment result in unequal size changes.
