JOURNAL OF EDUCATION AND SCIENCE, Volume 17, Issue 2, Pages 41-49
DOI: 10.33899/edusj.2005.81309

A simple, rapid ans sensitive spectrophotometric method was described for the determination of thymol. The method involves the oxidative coupling reaction of thymol with p- phenylenediamine reagent by sodium metaperiodate in alkaline medium leading to the formation of violet colored product (indoaniline) of maximum absorbance (ʎmax)= 550nm). The proposed method allows the measurement of 0.4-24μg ml-1.
The result obtained were both precise (RSD.) better than 2% and accurate (average recovery) 101.5% and molar absorptivity 7.45 X 103 (L.mol-1.cm-1) as well as Sandell's sensitivity 0.02 (μg cm-2). The method was successfully applied for the determination of thymol in mouth- washes and creams of pharmaceutical preparation and the results were in good agreement with the certified values and standard method. The common excipients used as additives in pharmaceutical do not interfere in the proposed method.

This study tackles the processes scheduling problem of multiprocessor and describing two algorithms from many algorithms for an array of dependent processes, which are represented by, direct a cj'clic
Graph on different forms correlation among the processes and tries to determine the duration each process would last on an arbitrary . figured out parameter, and to single out those processes for multiprocessor that purpose from the scheduling algorithm were carried out to get the best scheduling.
It appears from the comparison between two algorithms, first that "highest level first with estimated times scheduling algorithm", second that "smallest co-levels first with estimated time scheduling algorithm " has an effect on the schedule length(finish time). It has also been found out that shifting implementation time for each process while holding the correlation constant or, alternatively, shifting the correlation among processes and maintaining the selfsame time of duration has impact on schedule length. Moreover, it appeared that an increase in the number of dedicated processors that execute processes will also affect the lengthening of scheduling.
Accordingly, length of scheduling is considered a. significant parameter in the design of algorithms for multiprocessor scheduling.
