Benzoin thiosemicarbazone (BnTSC = L1). 2. p - propanal acetopheneden thiosemicarbazone (p - PrAPTSC = L2). The identity of these ligands have been characterized by spectral methods (UV - Vis, IR) and another physical properties (m.p.) and elemental analysis. Twelve chelate complexes of two ligands with Co(II), Ni(II), Cu(II), Zn(II), Cd(II), and Hg(II) were prepared and characterized after fixing the optimum conditions of molar concentration and mole ratio using (UV - Vis) technique of mixed solutions of the above ions with (BnTSC) and (p - PrAPTSC ). Electronic spectra of prepared complexes in ethanolic solution showed batho chromic Shift compared with that of free ligands. Thr IR, spectra (using KBr disc) of these complexes showed some charges compared to those of free ligands. New bards were observed indicating that the ligand (BnTSC) is coordinated to the metal ion as atridentate ligand while the other ligand (p - PrAPTSC) coordinated as abidentate ligand. Micro elemental analysis for all complexes were made, the percentage of metal ions were determined using flame atomic absorption spectroscopy. Good agreement was obtained between the found and calculated values. The stability of the complexes in solution were tested by evaluation of (stability formation constants) by electronic spectrum. In addition to determined the stability of there complexes at different time. Conductivity measurement for (DMSO) and (DMF) solutions at (1×10 - 3M) has shown non ionic character for all chelate complexes. Magnetic susceptibility measurements of Co(II) and Cu(II) complexes of both ligands and Ni(II) chelate complex with (BnTSC) show that they are paramagnetic, but the rest complexes show diamagnetic properties. Finally from the observations the geometric structure of the synthesized complexes were suggested

The RHAPrNH2 was treated with sulphuric acid to give a heterogeneous catalyst (RHNH3SO4H) via a one - pot synthesis at room temperature. The FT - IR, CHN, N2 adsorption - desorption, X - ray diffraction, scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X - ray (EDX), thermogravimetric analysis (TGA), differential thermal analysis (DTA) confirm the successful transformation of amine group onto RHAPrNH2 to the ammonium sulphate. The micro elemental analysis and EDX results showed an increasing in the carbon percentage and presence of sulfur which is not found in RHAPrNH2. The acidity test using pyridine adsorption study showed that the new heterogeneous catalyst (RHNH3SO4H) had a Brønsted acid site. Another aim of this study is to extract the cellulose from different agricultural and industrial waste sources. These waste are rice husk, palm kernel and waste office paper. It was found that the yield of extracted cellulose from rice husk was 25.1%, from palm kernel was 19.2 % and from waste office paper was 40.0 %. Cellulose from the above mentioned waste sources were hydrolyzed using RHNH3SO4H as a catalyst to produce glucose during 6 h, and the glucose was hydrolyzed afterward to other products within another 6 h. The optimum conditions time, mass of catalyst, temperature, reusability of the catalyst, effect of different solvents, and the chloride salts effect on the hydrolysis of cellulose were studied. The results showed that using 150 mg of RHNH3SO4H, in DMF or cyclohexanol as a solvent with LiCl at 120 ˚C for 12 h were the best optimum conditions. The maximum hydrolysis of cellulose to glucose over the catalyst (RHNH3SO4H) was 98 % during 6 h. The catalyst is reusable many times without a significant loss of catalytic activity.

Under optimum conditions of extraction Bi(III), the study showed that pHex=9 was more stable for extraction and gave higher efficiency because at this acidic function, there exists the best coordination bounding between Bi(III) and MIBSHA in presence of 40 μg of Bi(III) as optimum concentration giving favorites thermodynamic equilibrium for complex formation and this method of extraction depends on using Non - ionic surfactant 1% Tritonx - 100. And experimental study showed that 0.5ml of this surfactant suitable for forming Cloud point layer (CPL) with higher density and smaller volume to give the best extraction efficiency for Bi(III) with high absorbance and distribution ratio (D). The extraction efficiency also increased with increasing MIBSHA concentration as linear relation because any increasing in MIBSHA concentration is mean increasing in ion pair complex concentration and suitability so increasing in the thermodynamic equilibrium partition to the CPL. And this reflects the sensitivity of new complexing agent MIBSHA in coordination binding and ion pair complex formation in addition to extraction CPE methodology which depends on heating. The experimental study shows that the optimum temperature of heating was (90°C) that gives higher extraction efficiency because it allow to reached the best thermodynamic equilibrium in Cloud point layer formation with good dehydration, as well thermodynamic data was ΔHex=0.145KJ mol - 1, ΔGex= - 73.786KJmol - 1and ΔSex=203.669Jmol - 1K - 1 whereas the low value of enthalpy for Demonstrate extraction to approach another ion of ion pair association complex, also the extraction method is entropic region, and the experimental study about the effect heating time was 20min was the optimum heating time which gives the higher extraction efficiency with high absorbance and distribution ratio D, as this time of heating helps to reach the optimum thermodynamic equilibrium of Cloud point layer formation CPLwith higher dehydration from other hand time of heating indicate the quantity of heat which162is help to dominate on the moving of micelles inside formation cloud point layer CPL with good properties of extraction. Stoichiometric study by using four spectrophotometric methods and the study revealed that the more probable structure of ion pair complex of Bismuth ion Bi(III) extracted was [1 : 1]+ anion [Bi(MIBSHA)]2+;2No3 - experimented study about synergism effect by using Tri butyl phosphate (TBP) and methyl isobutyl ketone (MIBK) show that the extraction efficiency for bismuth ion Bi(III) increased with the presence of TBP or MIBK in aqueous solution by the effect of TBP and MIBK participation in the complex formation of Bi(III) also the experiments showed that there is one molecule of TBP or MIBK enters in the structure of ion pair complex of Bi(III) as [Bi(MIBSHA)(TBP)]2+;2NO3 - ; [Bi(MIBSHA)(MIBK)]2+;2NO3 - and TBP or MIBK enter in the complex instead of water molecule in the hydration shell of Bi(III) and increase hydrophobicity of ion pair complex and increased rate of partitioning to the CPL. As well as this study involved experiments about interferences effects as well as electrolytes effect and these experiments illustrated interferences effect to decline extraction efficiency because these ions form ion pair complex with complexing agent MIBSHA , that means a decrease in complexing agent MIBSHA concentration to form ion pair complex with Bi(III) so that electrolytes affect by increasing extraction efficiency of Bi(III) by effect of increasing Dehydration and destroyed hydration shell of bismuth ion to increase the chances of binding with MIBSHA for more stable ion pair complex. Later, this method was used coupled with suitable spectrophotometric application in the separation and determination of bismuth (III) in different samples.2 - Studies about Nickel (II)For nickel ion Ni(II) extraction from aqueous solution as ion pair complex used new laboratory prepared complexing agent AADAD , the spectrophotometric study for ion pair complex on Ni(II extracted into CPL showed maximum absorbance peak at wave length λmax=585nm and through the experimental study to limit optimum conditions and effective parameters. The study demonstrated that the optimum pHex was (9) which gives the highest extraction efficiency for nickel ion Ni(II by use complexing agent AADAD, whereas at this pHex favorable binding was given to form ion pair complex of nickel ion Ni(II with high concentration and stability as well as the method CPE for extraction Ni(II needed 0.5ml of non - ionic surfactant 1% TritonX - 100 which is affected to reach favorable thermodynamic equilibrium for aggregation of micelles in the state CMC for CPL formation with good163properties for the ion pair complex extraction of Ni(II) as well this extraction efficiency appeared with the presence of 50μg Ni(II) in aqueous solution to reach the best thermodynamic equilibrium for ion pair complex formation. Increasing AADAD concentration showed the existence of linear relation with linear increase in absorbance and distribution ratio and linear increasing in concentration stability and partitioning to CPL ion pair complex of Ni(II whereas CPE methodology depends on the temperature of heating, the experiment showed that 80°C was the optimum temperature that gives the higher extraction efficiency of Ni(II with thermodynamic data ΔHex= 0.1126KJmol - 1 , ΔGex= - 58.19KJmol - 1 and ΔSex=165.16Jmol - 1K - 1 . These values prove that the ions of ion pair complex for Ni(II) extracted into CPL approached one another with a high gegree and the method of extraction was entropic in region. The experimental study about the effect of heating time showed that 15min was the best time of heating that allows to reach a higher extraction efficiency of CPE method. Time of heating indicates the kinetic side of extraction method as heating for 15min at 80°C gave the quantity of heating that hels to reach the favorable thermodynamic equilibrium for CPL formation stoichiometry showing the more probable structure of ion pair complex extracted for Ni(II) which was [Ni(AADAD)]+;No3 - but synergism effect study showed that by using TBP and MIBK showed increasing extraction efficiency of Ni(II) with the presence of TBP or MIBK in aqueous solution because substitution water in coordination shell of Ni(II) in ion pair complex and effect to increase hydrophobicity, stability and partitioning to CPL. Also, the study revealed that adding one molecule of TBP or MIBK in the structure of ion pair complex of Ni(II) such as [Ni(AADAD)(TBP)]+;NO3 - , [Ni(AADAD)(MIBK)]+;NO3 - . So the studies tackled the effect of interferences as cations and electrolytes on extraction efficiency, later on, we used this method in the extraction and spectrophotometric determination of Nickel (II) in different samples.3 - Studies about Cobalt (II)The experimental studies concerning the separation, preconcentration and extraction of cobalt(II) as ion association complex by using the same complexing agent used with nickel (II) AADAD according to Cloud point extraction methodology. The UV - Vis spectrophotometric studies about the ion association complex extracted showed that the maximum absorbance of the complex of wave length λmax=530nm. As well as the extraction method according to CPE method showed (pH=8) was the optimum acidic function for extraction giving the highest absorbance and distribution value D because this pHex the best164coordination bonding between cobalt ion Co(II) and complexing agent AADAD so that high partitioning of stable complex to cloud point layer CPL. Moreover, the experiments showed that 0.5ml of Non - ionic surfactant, very stable for giving higher extraction efficiency because this volume of surfactant helps to reach the favorable thermodynamic equilibrium of aggregation of micelles to form CPL with high density and small volume and the micelles in case one approaches the other with the best dehydration to be in high hydrophobicity with good partitioning of complex to CPL. And in this case giving higher extraction efficiency, also, this extraction efficiency obtained when 60μg of cobalt ion Co(II was in the aqueous solution to give the best thermodynamic equilibrium to formation high stability ion pair complex extracted into CPL quantitively effect of temperature study showed that 80°C was the best temperature of extraction according to CPE method because in this temperature the best CPL was formed by aggregation and using dehydration at CMC state happen good extraction as well as thermodynamic data for extraction Co(II) was ΔHex=0.1014KJmol - 1, ΔGex= - 60.658KJmol - 1, ΔSex=171.86Jmol - 1K - 1. These data showed from the small positive value of enthalpy of extraction , the ions of ion pair complex extraction when one approach another to increase stability of this complex as well the large positive value of entropy of extraction demonstrates the dependence of extraction according to CPE and entropy. Then this procedure being entropic in region. Time of heating as the experiment study showed is 15min and was stable to give higher extraction efficiency. Because heating the solution at fixed temperature and time mean the quantity of heating help kinetically to reach thermodynamic and kinetic equilibrium for formation CPL. Then giving higher extraction efficiency. Stoichiometry study revealed that the more probable structure of ion pair complex extracted was [Co(AADAD)]+;NO3 - . Synergism study show presence TBP or MIBK in aqueous solution effect to increase extraction efficiency of Co(II) according to CPE method. Because complexing agent AADAD was not able to saturated the coordination shell of Co(II) ion in complex formation then the empty coordination position and occupy with water molecule and decline extraction efficiency , but TBP or MIBK able to coordinate instead of water in coordination shell and increase extraction efficiency, as well the study showed one molecule of TBP or MIBK able to enter in complex formed such as [Co(AADAD)(TBP)]+;NO3 - or [Co(AADAD)(MIBK)]+;NO3 - . So that the studies involved the effect of interferences as cations and electrolytes on extraction efficiency , later we used this method for the extraction and spectrophotometric determination of cobalt (II) in different samples.

PSEP/GC تم ايضا دراسة عمليات الاكسدة والاختزال لسداسي سيانيد الحديدات (II) باستخدام الـCyclic Voltammetry . وقد تبين ان ذروة الفصل ΔEpa - c ) ) بين قمم الاكسدة لايون فروسيانيد في محلول مائي هو 120 ملي فولت ، ونسبة التيار لقمم الاكسدة، IPA / IPC، كانت 1.6 لـ PSEP / GCE، مؤشرا انعكاسية وقابلية توصيلية جيدة للقطب المعدل. وبالتالي، فانه يمكن استخدامها لتحليل الجهد الكهروكيميائي . الخواص الفيزيائية للقطب المعدل PSEP / GCE تمثلت بالصلابة الجيدة، التصاق العالي على الاسطح المعدنية للقطب الالكتروليت الجامع ، بالاضافة الى الذوبانية والاستقرارية الجيدة للـPSEP على .GCE ايضا، الحساسية في ظل ظروف الـ cyclic voltammetry تعتمد بشكل كبير على تراكيز مختلفة من فروسيانيد ، الالكتروليت المستخدم ومعدل المسح . وقد لوحظ خلال معدلات مسح مختلفة بان قمم الاكسدة والاختزال للحديد / (III) الحديد (II) تمت بعملية معكوسة. | In this study, epoxidized palm oil (EPO) was utilized as a blended for poly butylene succinate (PBS) using chloroform as a solvent by solution casting process at six weight of PSEP. Fourier - transform infrared (FTIR) spectroscopy was used to identify the functional groups of PBS and PSEP blends. Thermal stability, biodegradable, and morphological properties of the blends were investigated by thermo gravimetric analyzer (TGA), and scanning electron microscope (SEM) technique. The FTIR spectra indicate that there are some molecular interactions by intra molecular hydrogen bond between PBS and EPO. All sets of PSEP blends show high thermal stability and significant improvement of biodegradable properties compared to pure PBS. Morphological results of PSEP blends show that EPO was good miscible with PBS. Aglassy carbon electrode (GCE) was modified with a poly butylene succinate - epoxidized palm oil (PSEP) film using a solution evaporation method to produce a new modified electrode PSEP/GCE. The redox process of K4[Fe(CN)6] during cyclic voltammetry was studied using the PSEP/GCE. It was found that the peak separation (∆Epa - c) between the redox peaks of ferrous cyanide ion in an aqueous solution is 120 mV and the current ratio of redox peaks, (Ipa/Ipc), is 1.6 for the PSEP /GCE, indicating good reversibility with good conductivity of the modified electrode. Hence, it can be used for voltammetric analysis. The physical properties of the modified electrode PSEP/GCE include good hardness, high adhesion to the metal surfaces of electrode collectors, solubility and good stability of the PSEP on GCE. Also, the sensitivity under conditions of cyclic voltammetry is significantly dependent on different concentrations of ferrous cyanide , the electrolyte used and the scan rate. At different scan rates, oxidation - reduction peaks of Fe(III)/Fe(II) were observed in a reversible process

Abstract: The present study was conducted to verify the relevance of lipids and lipoproteins levels and their byproduct of oxidation, malondialdehyde (MDA) in acne patients. The design of the project included one hundred acne patients (47% males and 53% females)and 40 apparently healthy individuals (control group). Total serum cholesterol (TC), high density lipoprotein cholesterol (HDL - C), triglycerides (TG), low density lipoprotein (LDL - C), very low density lipoprotein (VLDL - C) and MDA levels were measured in acne patients and the control group.The results indicated significant (P≤0.05) elevations for TC, TG, LDL - C, VLDL - C and MDA levels in acne patients with respect to those of the control group. Sex differences were obtained as rises forTC, LDL - C and MDA (P≤0.05) in males when compared with thoseof the females. The linear regression analysis exhibited significantpositive correlation for TC (r = 0.68, P≤0.05) and LDL - C (r = 0.48, P≤0.05) with ages of the control group but not in the acne patients.Smoker acne patients demonstrated significant elevations for TC, TG, VLDL - C, LDL - C and MDA (P≤0.05) in comparison with those of the control group, while nonsmokers acne patients showed significant elevations for TC and LDL - C (P≤0.05) during a comparable evaluation. Married acne patients indicated significant increases for TC, TG, VLDL - C, LDL - C and MDA (P≤0.05) when compared with those of the control group, while non married acne patients illustrated significant elevations for TG, VLDL - C, LDL - C and MDA (P≤0.05). The influence of treatment was studied, the data stated significant elevation for TG and LDL (P≤0.05), in treated acne patients when compared with those of the control group, while untreated acne patients showed significant increases for TC, TG, VLDL - C, LDL - C and MDA (P≤0.05) in comparison with those of the control group.These results suggested that oxidative stress is involved in the pathogenesis of acne. We believed that this study is the first to deal with changes of serum lipid profile and oxidative stress in acne patients.

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: تكمن اهمية الدراسة في كونها محاولة بحثية قانونية اصيلة ، خاضت في موضوع قلما كتب فيه على مستوى الدراسات القانونية العراقية والعربية، ما يعني انها ستضيف جديدا لمكتبتنا القانونية، وهي بداية لمشوار طويل اتمنى ان يستمر ليسلط باحثون اخرون الضوء على دور المحامي الدولي وقد يكون من زوايا اخر وان اتفقت من حيث المبدا وهو استكشاف دور المحامي لا في القضايا الدولية الانسانية فحسب، بل في قضايا دولية اخرى، كقانون البحار وقانون المعاهدات الدولية وغيرها.لقد ابدى مختصون في القانون الدولي العام ولدى اجراء الباحث مقابلات شخصية ارائهم حول اصالة الموضوع واهميته ، بل دفع البعض منهم الى التفكير مليا حيال مخاطر البحث فيه ، لكونه يمثل محاولة جديدة في عالم القانون الدولي العام ، والانساني على وجه الخصوص ، ما دفع بالباحث الى اختياره بعد التوكل على الله تعالى .لقد كتبت مؤلفات قديما وحديثا عن المحامي ودوره، ولكن لم يصل الى الحد الذي يكشف عن دوره في تطوير القانون الدولي الانساني، مره في كونه محاميا واخرى خبيرا ومستشارا ، وفي احيان اخرى عضوا فاعلا في منظمات دولية متخصصة في قضايا انسانية مطروحة على منبر البحث القانوني المقارن.ومن اجل البحث في هذا الموضوع، كان من الصعب الركون للدراسات العربية المتوفرة التي ركزت في اغلب الاحيان على دور المحامي على المستوى الوطني وفي القانونين الجنائي والمدني بالذات، ولهذا بحثت الدراسة في احدث الدراسات القانونية الاجنبية المتخصصة، الامر الذي دفع بالباحث الى الاستعانة بمحامين دوليين متميزين بدورهم ، فضلا عن بيان اراء قضاة المحاكم الدولية ، كالمحاكم الدولية لجنائية الخاصة في يوغسلافيا السابقة ورواندا، وغيرها، والمحكمة الجنائية الدولية ، وفيما يطرحه المحامون الدوليون في اثناء المرافعات.ولقد توصل الباحث الى نتائج عدة من اهمها : 1. كشفت الدراسة ان نشاة المحاماة لم تكن قديمة فحسب، بل انها متلازمة مع وجود البشرية، اذ تصدى لها اشخاص عرفوا ببلاغتهم وقدرتهم على الاقناع بالحجج العقلية فاصبحت سبيلا الى المدافعة والحماية لدرء كل ما يمكن ان يغير مجرى العدالة ويطيح بقداستها.2. على الرغم من ان المحاماة نشات وتطورت للتصدي الى المسائل القانونية الداخلية للدول، فقد شهدت تطورا ملحوظا لتتوسع الى نطاق ابعد من اهتمامات المواطن داخل مجتمعه او بلده، ولتصل الى ما يعرف اليوم بالمحامي الدولي وخصوصا في المسائل القانونية ذات الطبيعة الدولية.3. التغيير الملحوظ في المجالات الاصيلة والمرتبطة بدور المحامي، اذ عرف اولا المحامي عموما بانه الموكل في القضايا المدنية والجزائية الداخلية فضلا عن الدفاع عن المضطهدين في العالم، ونقصد بذلك الانتهاكات التي تطال حقوق الانسان وكرامته.اما اليوم فقد عرف المحامي بغير وصف، فهو المشارك في قضايا كان ابعد من ان يتصور المختص في القانون الدولي الانساني ان يكون له شان فيها، ونقصد بذلك تدخله في اثارة الراي العام الدولي ضد الانتهاكات الجسيمة التي تطال المدنيين والمقاتلين في اثناء النزاعات المسلحة الدولية وغير الدولية.4. اتضح من خلال الدراسة ان معظم قضاة المحاكم الجنائية الدولية هم بالاصل محامون بارزون، وهو دليل على ان المحامي الدولي هو الاقدر على ادارة المحاكم تلك وخصوصا في جانبها الاجرائي فضلا عن البحث في قواعد الاثبات.5. اتضح من خلال الدراسة الدور الضئيل للمحامين العرب بالمقارنة باقرانهم من الدول الاجنبية وخصوصا في الترافع امام المحاكم الجنائية الدولية فضلا عن المشاركة في تطويرها.6. كذلك يتضح ان دور المحامين العراقيين يكاد ان يكون معدوما في حقل القانون الدولي الانساني والجنائي منه بالذات، بالمقارنة مع اقرانهم في الدول العربية كمصر ودول شمال افريقيا ولبنان.7. كما يتضح من الدراسة ضعف التنسيق بين المؤسسات الحكومية العربية ونقابات المحامين العرب سواء في مسائل الاستشارة والترافع او في الاشتراك في المفاوضات الدولية المعنية بالاتفاقيات الدولية ذات الطابع الانساني والجنائي.8. اتضح من الدراسة الدور المتميز للمحامي العسكري في تقويم العمليات القتالية وبالخصوص في الولايات المتحدة ، وهو اسلوب ذكي للناي عن اي اتهامات قد تطال القادة او العسكريين في حال ارتكابهم لانتهاكات في اثناء النزاعات المسلحة.9. بلغ دور المحامي ذروته من خلال اعادة التاكيد على مبدا عالمية الاختصاص القضائي الدولي في مقابل الاختصاص القضائي الاقليمي في الجرائم ذات الطبيعة الدولية وبالخصوص نجاحهم في تحريك المسؤولية الجنائية الفردية ضد بونوشيه وايريل شارون.10. من جهة اخرى كان للمحامين الدوليين دور بارز في قضية معتقلي غونتنامو واثارة شرعية عدم احالتهم للمحاكم المختصة وفقا لاتفاقية جنيف الثالثة لعام 1949، بل وفي احراج الادارة الامريكية بشان مستقبل معتقل غونتنامو، وهو ما يعد اسهاما في ردع الدول غير الممتثلة لقواعد اضحت امرة على الصعيد الدولي.

Abstract: Womans topic is of the important topics that is dealt by many academic human studies as it relates many aspects such as the social, human, political and religious. The philosophical studies had participated in dealing with this topic, many philosophers , such as Aristotle and Plato the greatest philosophers, had dealt with this topic where each one of them had a different approach. For Plato the Woman is an independent human equal to Man , while for Aristotle, she is a natural creature governed by the Man as he enjoys a perfect reason while she does not. This research is a contrastive study of Woman for Aristotle and Plato, where it tackles Woman in the pre - Plato society, the Greek society of the gods and myths. It shows Woman suffer in those myths where she did not enjoy her rights and freedom as a perfect independent creature in front of the Man who was the governor and the dominator. This was represented by the god Zeywos and his wife Hira whose suffer was just like that of the ordinary Woman. Then the researcher moves to Platos era who, as a result of the miserable situation of the Woman, had put the rules or laws that call for liberate Woman and allow her to participate in the political affairs, governing and other so on. Society, and the following Philosophers such as Aristotle had rejected these ideas where Aristotle represented the Greek status and reality by his opinions so he insisted on limiting Woman to the domestic affairs. Moreover he had referred to the biological aspect believing that Man is responsible for procreation while Woman is just a store or a room for the baby to sleep in and that nature had ruled Woman to serve Man. This study obtain a stet conclusions that could be summarized as following : - 1 - Woman, whether she was a god or a real Woman, had a low status before the Man who was the governor and the dominator while she was the governed and the dominated. 2 - The Greek society had a rigid opinion upon the woman when she had been deprived of participation in ruling, policy or authority. Moreover she had been prevented from attending the courts or trails which were restricted to Man.3 - Platos idealism had put Woman in an idealistic status that he had equalized her to Man. This new status involved her to neglect the family and that was the main reason of rejecting his opinions, though he had modified them.4 - Aristotle's theory upon Woman as a store or a room for the baby to sleep in had been referred to nature without science aspect where the scientific theories and discoveries proved that Woman played the greatest role in defining the babys sex especially that she carries the chromosome ( xx ) who select the chromosome ( X Y ). It was necessary to criticize the mentioned point to show the injustice against Woman by depriving her rights and freedom as a perfect independent human being.

Abstract: This research - field dealt with ethics and religion in the pragmatic philosophy, particularly of William James and John Dewey. It included four chapters. The first chapter presented the most important philosophers who represented the pragmatic philosophy and shed light on the most outstanding subjects and problems on which those philosophers made their research.The second chapter is mainly based on the ethics in William James’s philosophy. In the first section, which is entitled. Ethics between psychology and Metaphysics, we handled the origin of the ethical rules in addition to the source of Good and Evil. Finally, it touched upon the conscience idea. Accordingly, it seems that James treated ethics from a psychological point of view in the way that ethics are considered as relative and not absolute. This idea is also represented in the second section of the subject, entitled the Ethical principle, in which he criticised the standard solutions, trying to suggest the pragmatic philosophy for this standard question. In the third section, the researcher handled the Meliorism in James’s philosophy in which James looked at the world optimistically through the defeat of evil and the victory for good. The third chapter included the ethical subject in John Dewey’s philosophy. In the first section, Dewey treated the relationship between the means and ends which is regarded as the basis for the ethical problem.In the second section which represents the core of the ethical theory, Dewey tries to talk about the morals of the individual and society. In this section, we find Dewey contradicts James in that he dealt with ethics sociologically. In the final section of this chapter which is entitled Freedom and the Ethical optimism, Dewey made a complete agreement with James in his theory of Meliorism. To end this chapter, we find that Dewey called upon the scientific ethics which are regarded as similar to other experimental sciences. As a result of this, we had to use and apply the approaches of the scientific research.In the ending chapter, the researcher discussed religion in Dewey and James’s philosophy . James’s birth in a religious family forms the effective effect of his tendency and treatment of religion psychologically.This is quite evident in the first section which is under the title “the will to believe’, in which James believed that religion is a personal matter and there are images of the religious experience which are equal to the number of pious people.In his theory, mentioned before, James considered every individual as one who has the right to believe and to be faithful because the logic of mind can’t prove validity for everything. James applied this firstly on the idea of God.Dewey’s attitude towards religion was negative in that Dewey opposed all heavenly religions regarding them as constant social values and principle because they called upon absolute values which are beyond the human nature. In this viewpoint, Dewey showed that the right religion is the one by which all humanity should restrict to it

Abstract: Praise be to Allah the Lord of worlds, prayer and peace be upon the most honorable prophet and messenger Mohammed and his pure progeny….The Umayyad ascendancy had not achieved the approval of all, or even most of, Muslims, they had took over power by muzzling everyone who refused them or rejected their project of governance, so the obsession of keeping power or authority was an effective element for them to work hard, using all means and methods to achieve their aim. Their policies were either arousal of an interest or terrifying. Arousal of an interest is the subject of this research , it has different aspects; political, economical, intellectual and social. The real reason of studying this subject is the pure desire to show the historical truth concerning the Umayyad history, exposing their false believing on Islam and their serious attempts to forgery truth and fabricate stories depending on illegal methods where their theory of governance did not consider the Islamic principles. The research includes a preface, three chapters preceded by an introduction and followed by a conclusion. The preface gives the definitions of arousal of an interest in language and tradition, its significance in the holy Qur'an and prophetic Hadith.The first chapter deals with the arousal of the political desire within three topics : - the Umayyad attempts to win the support of the major personalities or figures by intrusting the serious post or position to them in addition to the authorities, the Umayyad efforts to win the support of the politicians by arguing them into their political project, so indulgence and mildness was their policy even with their enemy, and the Umayyad efforts to win the support of their foes by forgiving those who were opposing them.In the second chapter the researcher discusses the arousal of the economical interests within four topics to show how did the Umayyad had invest the money of Muslims in an illegal way to gain the support of the people to achieve their aim where this money had great effects resulted in the liquidation campaigns. It also shows the Umayyad offensive and harmful means to control the people potentialities according to studied policy, and their serious and hard attempts to enhance their protection by encouraging the few people, princes, leaders and officials, who supported them, by the exceptional gifts and endowments : - money, positions and agricultural and residential lands or plots to connect them with the Umayyad regime. In the fourth topic the Umayyad way of treating the out comers had been exhibited; they had welcomed them and were so generous so the out comers, with returning to their countries, would give a good image for the Umayyad.The third chapter is devoted to the intellectual and social aspect of the arousal of interest. It has four topics to study : - the Umayyad efforts in fabricating narrations that make people love them, the Umayyad efforts to efface their foes virtues, the Umayyad efforts to induce the jurists and the Umayyad efforts to induce the Arab tribes by connecting them with the relationships of marriage, respectively.The conclusion carries the most important results of the policy of the arousal of interests in the Umayyad era.
