An attempt was made to estimate on theoretical treatments the thermodynamics functions of corrosion of carbon steel (ST37 - 2). The kinetics of corrosion and inhibition of the carbon steel specimen have also been studied by measuring the corrosion rates in presence and absence of dyes (inhibitors) at several temperatures in the experimental temperature range. In general the results of the corrosion experiments showed a shift of the corrosion potentials towards more negative values with the rise of temperatures.The corrosion current densities generally increased with the rise of temperature reflecting the increasing rate of carbon steel (ST37 - 2) specimen corrosion with increasing temperature .The linear sections of the cathodic Tafel lines shifted almost to each other ,and a similar behaviour was found for the linear sections of the anodic Tafel lines .The Tafel lines maintained their linearity and slope at all experimental temperatures suggesting no alterations in the mechanisms of the cathodic and anodic reactions with the variation of temperature .The values of the Tafel slopes suggested that the proton discharge at the cathode and the metal dissolution at the anode were the prevailing rate determining - steps of the reactions which occurred at the cathode /solution and anode / solution interfaces .The measured corrosion potentials and current densities enabled a thorough investigation of the thermodynamic and kinetic aspects of the carbon steel (ST37 - 2) corrosion in the studied solutions. Thermodynamics of carbon steel (ST37 - 2) specimen corrosion have been deduced from their corrosion potentials and the resulting data showed the generally the feasibility of the corrosion reactions and that the formation of the corrosion products was accompanied by the variation of the enthalpy values between negative and positive values and increase of the entropy values of corrosion with variation of temperature . The kinetic data showed the operation of a compensation effect in the corrosion reaction of carbon steel(ST37 - 2) . Also thermodynamics of the dyes adsorption process (inhibition process) in different temperatures were calculated ,the resulting data shows the values of enthalpy and entropy of adsorption ranged between positive and negative values while the values of Gibbs free energy of the adsorption process were positive for all dyes. As for the inhibition efficiency was found as follows : A. Murexide dye was acted as good inhibitor in 2.5 x10 - 6 M H2SO4 and showed the highest inhibition efficiency reach to 99.8% when using concentration of 5 ppm of dye and within the temperature range 333 - 303 K. B. Sudan III dye showed the highest inhibition reach to 99. 6% in 2.5 x10 - 6 M H2SO4 concentration when 150 ppm of dye used and at temperature of 313 K. C. Carmine dye showed the highest inhibition efficiency reach to 99.4%in2.5x10 - 6MH2SO4when using 25 ppm of dye and at temperature of 333 K. D. Leishman dye showed the highest inhibition efficiency in 2.5 x10 - 6MH2SO4at dye concentrations of 50,25,5 ppm and at temperature of 333 K . In general the tendencies of the four dyes for corrosion efficiency followed the orders : 5x10 - 3 M H2SO4 ) Murexide ˃ Leishman ˃ Sudan III ˃ Carmine ( 2.5x10 - 6 M H2SO4) Leishman ˃ Sudan III ˃ Carmine ˃ Murexide (Leishman ˃ Sudan III ˃ Carmine ˃Murexide ( 3.5x 10 - 6 M NaOH) Electronic scanning microscopy was used to study the Crystal structure of a carbon steel(ST37 - 2)specimen after being subjected to corrosion in the absence of dye and presence in a concentration of 50ppm of each dye and at temperature of 40oC and in a solution of sulfuric acid with a concentration of 2.5 x10 - 6 M H2SO4 as a sample for microscopic examination, the microscopic study found that corrosion of carbon steel (ST37 - 2)is of the style of the Austenitic and ferritic Crystal grains as well as crystal boundary corrosion

Abstract: تضمن الجزء الاول من البحث تحضير اربعة كواشف عضوية جديدة هي مشتقات ازو لمركب الباراكريزول وقد تم تشخيص الكواشف المحضرة من خلال اطياف الاشعة فوق البنفسجية - المرئية (UV - Vis) فضلا عن قياس اطياف الاشعة تحت الحمراء IR)) وتم اجراء قياسات نسب العناصر الدقيق ( | The first part of this study included perpetrating four new organic reagents which are derivatives of P - cresol. Its identification was done by UV - Vis spectrophotometer, IR and C. H. N. Depending on the results, we found the correspondence between the theoretical calculation and the experimental ones with a way to suggest the final structures of the prepared reagents. The purity of these reagents was tested through thin layer chromatography.The prepared reagents are : 1. 2[(4 - Methyl phenyl )azo] - 4 - Methyl phenol (MePAMP)2. 2[(4 - Chloro phenyl )azo] - 4 - Methyl phenol (CPAMP)3. 2[(4 - Methoxy phenyl )azo] - 4 - Methyl phenol (OMePAMP)4. 2[(4 - Nitro phenyl )azo] - 4 - Methyl phenol (NPAMP)The second part deals with the study of chromatographic behavior of organic prepared reagents dissolved in ethanol according to gas chromatography on stationary liquid phases as capillary columns with different polarities as zebron (FFAT) which is characterized with high polarity, silica fused (BP10) with a medium polarity and poly phenyl siloxine (OV - 5) that appears with low polarity.Gas chromatography was equipped with a flame ionization detector (FID) and the nitrogen as carrier gas with flow rate 30cm3min - 1 at different column temperatures ranged 100C increments depending on columns maximum operation temperature, column inlet temperature and detector temperature were higher than the separation column (25,50) 0C respectively.This investigation attempts to find the optimum conditions for the sequential separation were defined for the azo compounds of all capillary columns such as injection, applied pressure inlet of column, gas flow rate as well as the conditions of the efficient separation.The order of elution and resolution of compounds on various stationary liquid phases were normal chromatographic behavior which is decrease in specific retention volumes with increase of column temperature through the relationship between logarithm of specific retention volume for the studied compounds against reciprocal of absolute column temperature which is observed generally linear relation for all compounds on different liquid phases by using (Clausius - Clapeyron) , then calculate the thermodynamic parameters ?H0 , ?S0 and ?G from the slope and intercept respectively the negative values of partial molar enthalpy ?H0 of solutions indicate to highest interaction between liquid phases and separated compounds. The results show that the zebron (FFAT) consider the high negative value of ?H and the reaction was exothermic, on other hand the highest negative value of ?s means less random of solutes on some liquid phase , so it was more selective towards to prepared azo derivatives of p - cresol. Also calculated separation factor (RS),number of theoretical plate (N), equivalent highest of one theoretical plate (HETP) respectively for mixture of studied compounds on various liquid phases.The precision and accuracy of the prepared organic reagent (MePAMP) from 0.06% to 1.44% for (CPAMP) from 0.91% to 1.5%, (OMePAMP) from 0.03% to 1.42% and finally for (NPAMP) from 0.06% to 1.6%

Abstract: The present study aims at investigating the relationship b etween oxidative stress and hyperlipideamia in diabetes mellitus. For this purpose,(120) diabetes patients were chosen (48 type1 patients and 72 type2 patients). This sample of (120) patients was compared with a group of (50) healthy subjects. The malondialdehyde (MDA) (one of the markers of oxidative stress), serum total cholesterol(S.TC),triglycerides (S.TG) high density lipoprotein cholesterol (HDL), low density lipoprotein cholesterol(LDL) and very low density lipoprotein triglycerides (VLDL) were all measured via the enzymatic methods. Results indicated a significant increase(p<0.05) in the levels of (MDA),(S.TC),(S.TG),(HDL),(LDL) and (VLDL) in diabetes patients of both types, as compared with healthy subjects. The same fact holds when comparing the two types of patients. A significant increase (p<0.05) was also observed in the levels of (MDA),(S.TC),(S.TG),(HDL),(LDL) and (VLDL) in male and female diabetes patients of type1 as compared with healthy subjects. As for type2 patients the increase in the same values was(p<0.01) as compared with healthy subjects. The comparison of male and female patients showed a significant increase(p<0.05) in the levels of (S.TC),and (VLDL) only in type1. It was also found that age is an influential factor in the criteria of serum lipids and (MDA) levels in patients of both types, except in case of(S.TG)and(VLDL) in type2 patients where age proved irrelevant. Moreover, results indicated that (BMI) has an impact on (MDA),(S.TC),(S.TG),(LDL) and (VLDL) levels. The duration of the disease in patients of both types also produced a significant increase(p=0.05) in (MDA) levels and serum lipids criteria. The complications suffered by the patients because of diabetes also produced a significant increase (p<0.05 - p<0.005) in (MDA) levels and serum lipids criteria as compared with those free of such complications for both types. No significant correlation was found between MDA level and levels of serum lipids in all patients and in both types except(VLDL) in type2. All these results prove the correlative relationship between oxidative stress and serum lipids criteria in diabetes mellitus.
