This has been already shown in former studies [e.g., 23].
It has been already shown, e.g., in [4] that for (3.1) and (3.2) a solution exists.
Chitosan has been already shown to serve as vehicle for sustained drug release by chitosan-vanadium(IV) complex from a chitosan gel matrix.
Unmodified chitosan has been already shown to serve as vehicle for sustained drug release by controlling the diffusion of chitosan-vanadium complex from a chitosan gel matrix.
That is a general theoretical conclusion from special tensorial analysis of potential fields and has been already shown for the gravity potential by Rummel and van Gelderen (1992).
It has been already shown that the proteolytic activities of the proteasome machinery decline during aging in several human tissues as well as in senescent primary cultures [12].
An example of time variation of both field-aligned and perpendicular directions of Poynting flux has been already shown in Fig. 2. The Poynting flux of Pc 5 waves was calculated for most of selected events.
As it has been already shown by the performance graphs, the result is that AWPP serves higher-priority traffic more efficiently, which is the main objective, whereas POAP performs better on serving LP traffic.
In fact, it has been already shown that size exclusion chromatography affects the architecture of humic supramolecular associations [2] by rearranging heterogeneous molecules into less complex assemblies and enhancing their analytical visibility.
This indicates that amine nitrogen atoms of chitosan are not involved in VO(IV) coordination and supports that only oxygen donors of hydroxyl groups participate in VO(IV) complexation, as it has been already shown by the potentiometric results.
At this time point, it has been already shown that little amount of PEG-modified gold nanorods was observed in the blood and that most gold nanorods were distributed to organs[7, 9].
