The paper deals with studying the effects of the experimental factors on the values of stability constants (K) of the dyes formed by the reactions of aromatic aldoximes as 2-hydroxybenakloxime, 2,4-dihydroxy benzaldoxime and 2-hydroxy-l-naphthaldoxime with diazotized sulfanilic acid salt.
Experimentally, two physic; parameters have been founded to be effective on the value of K as the presence of three surface active reagents [cetylIrimethyl ammonium bromide (CTAB), sodium dodecyl sulphate (SDS), starch] and a four polar solvents (water, inethanol, ethanol, n-propanol).
Generally, the stability constant alue of any dye formation is determined by knowing the structure of aldoxime, the dielectric constant of the me J mm, the type of surfactant and pl-1 under study.

This paper deals with the preparation of twelve aliphatic and substituted benzoic acids.the structures of these acids are confirmed by some physical methods.
The main object of the paper is studying the possibility of association in these acids by physical methods,namely the UV,IR spectra,melting point and distribution methods.
The mechanisms of association in these acids in benzene are happen by either hydrogen bonding alone or hydrogen bonding in addition to the ion induce dipole association methods.This depends on the structure of the acid and the temperature of the solution. The idea of ion induce dipole in founded here for the first times as suggested from the collected experimental results. Finally a suitable interpretation is given read any point as support by reference

A spectrophotometric method for the determination of trace amounts of some sulphonmides (six compounds) in aqueous solutions is described. The method in based on dizotisation and coupling with pyrogallol to form a yellow coloured, stable and water- soluble azo-dye which shows maximum absorption at 420 nm. Beer's law is obeyed over the concentrations range of 0.4-14 ppm. The relative error is -2.47 to + 3.41 % and the relative standard deviation is ±0.51 to ±2.9% depending on the concentration level. The proposed method has been successfully applied to the determination of sulphacetamide sodium in eye drop drug.

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.
