Abstract: The research included synthesis ,characterization and evaluation of two new corrosion inhibitors (Bis(2 - ((2 - hydroxyethyl) thio) ethyl) terephthalate (BHET) and Bis(2 - ((6 - Mono malic acid - hydroxyl ethyl ester) sulfonyl) ethyl terephthalate (BHMET) from recycled waste polyethylene terephthalate .The best percent of the two corrosion inhibitors were reached after many experiments, which included study many factors like temperature, the equivalent weight of reactants and others. The synthesized corrosion inhibitors were characterized by FTIR and 1HNMR spectroscopy and thermal analysis . As measured for inhibitors thermal stability TGA&DTA has been found to be inhibitors stable thermally It was found that the inhibitor (Bis(2 - ((2 - hydroxyethyl) thio) ethyl) terephthalate stable up to a temperature (240) ˚C and the inhibitor Bis(2 - ((6 - Mono malic acid - hydroxyl ethyl ester) sulfanyl) ethyl terephthalate stable up to a temperature (230) ˚C This is evidence of its effectiveness within these thermal grades of industrial processes, particularly their work inhibitors corrosion.The two inhibitors were evaluated as corrosion inhibitors using hydrochloric acid as corrosion media for carbon steel alloy( carbon steel C1010) . The factors effect on the rate of corrosion like temperature , concentration of inhibitor were studied by the electrochemical technique using the Tafel plot.The obtained results at temperatures range ( 298 - 328) K and concentrations (10 - 50) ppm were used to calculate many factors that determined the efficiency of the inhibitor like : corrosion rate , corrosion current , charge transfer resistance , Anodic Tafel constant , Cathodic Tafel constant , corrosion potential and inhibitor efficiency. It was observed that the corrosion rate increases with increase of temperature and decreases with increase of the inhibitor concentration in the same temperature. The Results showed that both inhibitors had very high inhibition in reducing the corrosion rate .The inhibition efficiency reached (97.1%) for (Bis(2 - ((2 - hydroxyethyl) thio) ethyl) terephthalate for the 40 ppm at (308) k and (96.2%) for the Bis(2 - ((6 - Mono malic acid - hydroxyl ethyl ester) sulfonyl) ethyl terephthalate for the 50 ppm at (298) k.Many thermodynamics functions was calculated ,activation energy Ea , activation entropy ΔS* , activation enthalpy ΔH* and free energy ΔGads during the different experiment conditions, which was indicated of the corrosion inhibition efficiency and the type of the inhibition. The obtained results showed that the two inhibitors were very efficient to reduce the corrosion rate in the acidic media and from the ΔGads data the type of adsorption was physisorption and chemisorption. because the value of ΔGads was higher than ( - 20 KJ/mol) and less than ( - 40 KJ/mol).

Abstract: In this study five ligands were prepared from condensation two amines (4 - methyl benzene - 1,2 - diamine and ortho phenylen diamine ) with two aldehydes( 4 - isopropyl benzaldehyde and 4 - diethyl amino benzaldehyde.These ligands were identified by elemental analysis, FT - IR , UV - visible, 1HNMR , 13CNMR and mass spectroscopy. The proposed chemical structure of these ligands are suggested as following : Binuclear tetrathiocyanates complexes [MM'(SCN)4 ; M=Co,Ni,Cd : M'=Cd,Hg] were first prepared by the reaction of metal nitrates with potassium thiocyanate and then solutions from two formed metal thiocyanates were mixed in 1 : 1 molar ratio.Fifteen bridged thiocyanate complexes were prepared from the reaction of Schiff base ligands with binuclear tetrathiocyanate complexes in 1 : 1 molar ratio . These complexes were characterized by elemental analysis, FT - IR , UV - visible ,mass spectroscopy ,atomic absorption ,thermogravimetric analysis, molar conductance and magnetic susceptibilities. The results were indicated that the found percentage of C ,H and N for the prepared complexes were closed to their theoretical values . Also IR spectra showed that stretching vibration of azomethine group in the complexes was shifted in comparison with ligands in addition to appearance of bands belong to bridged and terminal thiocyanates indicating the bonding of ligands with metals. Mass spectroscopy also proved the structure of complexes by displaying peaks of molecular ion and some basic fragments. UV - Visible and magnetic studies gave an idea about geometry and coordination number of these complexes through location of electronic transition and number of unpaired electrons in outer energy levels .Atomic absorption measurements explained that the reaction of th e ligand with the metal complexes was 1 : 1 molar ratio , also the percentage of the metals in the prepared complexes was in good agreement with the theoretical values . It was found that the molar conductance values of the complexes were low indicating that all prepared complexes have non electrolytic properties . Farthermore , some prepared complexes had a good thermal stability depending on some thermal parameters calculated bythermogravimetric carves .In addition , the biological activity of the prepared ligands and theircomplexes were studied by using two types of bacteria (S.aureus , E.coli)and fungi (A.niger , A.ftavus) . It was found that all compounds havesignificant antimicrobial activity . Cytotoxicity of these compounds wasevaluated . These compounds have not toxicity on the red blood cells in comparison with standard compounds such as sodium cyanide .The proposed chemical structures of the prepared complexes were suggested as following : AC1 AC2

Abstract: The abstract of the present work for the synthesis of the new heterocyclic phenolic 1,3,4 - oxadiazole and their chelating polymers is outlined below : Part One : Organic Synthesis.1) Conversion of hydroxy benzoic acid derivatives to their corresponding esters (4 - 9) using standard procedure (Fiesher esterfication). 2) Reaction of hydroxyl benzoate derivatives (4 - 9) with hydrazine hydrate afforded the corresponding acid hydrazides (13 - 15). 3) The reaction of acid hydrazide derivatives (13 - 15) with carbon disulfide in the presence of alcoholic (KOH) yielded their corresponding 5 - (substituted) - phenyl - 2 - mercapto - 1,3,4 - oxadiazoles (19 - 21). 4) 2 - (methyl/butyl thio) - 5 - (substituted) - phenyl - 1,3,4 - oxadiazoles (24 - 27) were synthesized by alkylation reaction in basic media of oxadiazoles with methyl iodide and n - butyl bromide respectively. 5) The acid hydrazides (13 - 15) were treated with carbon disulfide and alcoholic (KOH) to form their corresponding polar salts, namely potassium - 3 - aroyl dithio carbazinate derivatives (16 - 18). 6) The dehydration cyclization reaction of the above polar salts (16 - 18) using hydrazine hydrate afforded the corresponding 5 - (substituted) - phenyl - 4 - amino - 2 - mercapto - 1,2,4 - triazoles (22, 23). 7) Eight new chelating polymers (28 - 35) have been synthesized by the condensation of phenolic oxadiazoles (19 - 20) and phenol or disubstituted hydroxyl phenol (hydroquinone, resorcinol, and catechol) with formaldehyde in (1 : 1) molar ratio in the presence of (KOH) as a catalyst. The structures of the prepared organic and polymeric compounds that have been synthesized were established by physical (melting points, color), elemental analysis (C.H.N, S), FT - IR, H1 - NMR, C13 - NMR and the results obtained are compatible with assigned structures. Part Two : Analytical Study. The chelation ability of these eight polymers were studied for Ag+, Al3+, Ca2+, Cd2+, Co2+, Cr2+, Cu2+, Hg2+, Mg2+, Ni2+, Pb2+ and Zn2+ ions using batch equilibrium method using flame atomic absorption spectroscopy (F.A.A.S). The different factors affecting loading capacities for the studied ions such as type of polymers, pH and treatment time were studied and the results obtained from figures (4 - 1) to (4 - 104) listed in chapter five shows that the loading capacity in (mg ion / g resin) increased with : 1) Increasing the pH value of the studied ion solution.2) Increasing the treatment time. Thermal stability of the eight synthesized polymers (28 - 35) were studied by thermogravimetric analysis (TGA), they showed good thermal stability, these results are discussed in relation with the presence of 1,3,4 - oxadiazole ring in the side group of the prepared networks

Abstract: This study included the preparation and the diagnosis and study the biological activity of some new organic compounds containing amine and azomethine groups and complexes ions with platinum(II) and palladium (II) and rhodium (III) ions.This thesis is divided into four chapters. In the first chapter, a general introduction for platinum metals group and of their complexes including : amine and Schiff base ligands have been literately reviewed. The concerned complexes have related to drugs potentially are anticancer active, therefore, this chapter summarized the important roles between the structure and activity for potentially active anticancer drugs which containing platinum metal complexes .The second chapter of this thesis shows the preparative methods of two types of ligands. The first type ligands concerned preparation method of two newly bidentate amine ligands namely : N - (3 - phenylpropyl)ethane - 1,2 - diamine (1) and N,N' - bis(3 - phenylpropyl) ethane - 1,2 - diamine (2) by reaction of ethylene diamine with 3 - phenypropyl bromide in 1 : 1 and 1 : 2 mole ratio, respectively. The second type ligands concerned preparative methods of six newly Schiff base ligands by reacting of o - phenylenediamine with 2 - furyldehyde, ferrocenecarboxaldehyde and acetylferrocene in the mole ratio 1 : 1 and 1 : 2respectively namely : N - 2 - furylidinebenzene - 1,2 - diamine (3)N,N' - bis(furylidine)benzene - 1,2 - diamine(4)N - ferrocenidenebenzene - 1,2 - diamine (5)N,N' - bis(ferrocenidene)benzene - 1,2 - diamine (6) N - 1 - ferrocenylethylidenebenzene - 1,2 - diamin (7) N,N' - bis(1 - ferrocenylethylidene)benzene - 1,2 - diamine (8) o , this chapter describes the synthesis of a new twenty four complexes ofPt(II), Pd(II) and Rh(III) ions with ligands (1 - 8) . The third chapter includes the results and discussion. All the prepared compounds 1 - 32 were characterized by elemental analysis CHN, Conductivity measurements , 1H - NMR ,FT - IR and UV - Visible spectroscopic techniques. All the prepared compounds 1 - 32 are in good agreement with the suggested structure. These data confirmed that the prepared ligands 1 - 8 coordinate with Pt(II),Pd(II) and Rh(III) ions by nitrogen atoms of amino and azomethine groups as a bidentate ligands. The molar conductivity study indicate that platinum(II) and palladium (II) complexes are neutral and behave as non - electrolytes in DMSO solvent at room temperature while rhodium (III) complexes behaves as 1 : 1 electrolytes in the same conditions.Antibacterial activity of all the prepared compounds 1 - 32 beside their interaction with human DNA are shown in the fourth chapter of this thesis. The antibacterial activity of compounds 1 - 32 against two types of bacterial : the first negative towards Gram stain (i.e. Escherichia coli) and against positive towards Gram stain (i.e. Staphylococcus aureus) were tested. These data proved that only compounds 1, 2, 4, 5, 6, 7, 20, 29 and 32 have antibacterial activity for growth inhibition of Staphylococcus aureus whereas only 1, 2, 4, 21 and 29 have antibacterial activity for Escherichia coli. On the other hand, DNA interaction study of complexes 9 - 32 with human DNA showed that all these complexes are binding with DNA which is enhances the probability of usingthese complexes as drug alternatives.

These salts were prepared by two methods chemically and, for the first time, electrochemically method. The evaluation of conductance data was carried out by minimization technique using theoretical conductance equations of the complete and modified forms of Pitts and Fuoss - Hsia. Quantitative results showed that these salts do not behave as ''strong'' electrolytes , and that their dissociations are far from complete . The abnormally low conductances of these electrolytes are not due to the presence of electrically neutral molecules but to the ion - pair formation. The Walden product values, as well as the standard thermodynamic functions (∆H˚ , ∆G˚ , ∆S˚ ) for the association reactions for the four temperatures studied, have been evaluated from the temperature dependent of Λ˳ and KA respectively. All the obtained quantities were reported and discussed . Thermal stability of PVC was studied by using magnesium, barium , cobalt , copper , nickel and zinc adipate as stabilizers

Abstract: In recent years, the statistics presented high incidence rates of breast cancer.So, early detection of breast cancer considered one of the highest healing rates for most cases, where the treatment at early stage is very easy and involves removal to malignant tumor from breast without needed to remove all breast. As well the cost of treatment is very economical with early diagnosis, while at a late stage, the cost associated with treatment is higher. In addition, the prevention have role to reduce risk by avoid catalysts that cause Incidence and associated with risk factors. For these reasons and others, we present the proposed method for designing a risk assessment tool for breast cancer prevention and early detection based on demographic risk factors (DRF) and using Neuro - Fuzzy System (NFS) in designs risk assessment model that help doctors and patients in assess risk of Incidence through providing better and more reliability results.In this thesis, the proposed method is a process of several stages. The first phase included statistical study to identify problem of research based on statistics in Basra, through apply the study on patients community at Al - Sadir Teaching Hospital in Basra (Oncology Center), that represent main center in Basra for the treatment of cancer. Three and most important phase includes the proposed approach for design assessment model using Neuro - Fuzzy system (NFS) in two approaches. the second approach suggested using Fuzzy c - means (FCM) algorithm with Neuro - Fuzzy system to improve the first approach that just use Neuro - Fuzzy system (NF). The proposed method is focused to solving basic research problem to prevention and early detection of breast cancer.The proposed method achieved high results when compared to other methods and tools. The success rate of proposed assessment tool is 94%, and it is higher rate among other assessment tools (Gail, IBIS) that obtained by match the result for assessment of test data (50) with the expert opinion (the real result). Programming and testing of proposed method by used Matlab 2013

Abstract: The rapid development and tremendous computer and communication technologies and the proliferation of global networks, has led to the emergence of many techniques to transfer confidential information including encryption (Cryptography), and as a result of piracy And penetrating these techniques need arose for techniques and methods more sophisticated and difficult to transfer confidential information securely. Because of the increase in the number of attacks recorded during the exchange of electronic information between the source and the recipient may need to use a more powerful way to secure data transfer, encryption methods are combined And hide the information together for the purpose of setting up a mechanism to improve confidentiality and because these methods shared goals and common services in protecting the confidentiality, integrity and availability of information from unauthorized access and thus check mechanism High security integration to preserve data confidentiality.The research aims to use the method to hide secret information (picture or sound) into audio files (audio file) (wav) as cover in such a way as to ensure that information is not piracy, secret message encryption Sleek encryption before concealment by making the size of the stego - audio is equal to the size of the original file.As the audio file is the output of a process of hiddin similar to the original file and for the human ear to feel the change. By segmenting the original soundtrack cover frames (frames) and apply the random function to locate hidden after the colored image layers in case confidential information picture or sound to hide the hash to Frameworks and then applying the function for selecting locations for concealment and then apply the least significant bit technology (Siginfcant Least Bit) for concealment.In the case of the recovery process is contrary, embedded audio file fragmentation occurs (stego - audio) and apply the random function for selecting locations for concealment and decrypt the message.Use a key in a hash process sound represents the size of the picture you want to hide, and it represents the number of frames (frames) and serve as a key to encrypt the original audio as we use an algorithm to generate a sequence of key Homologous between the sender and recipient to Sleek encryption to increase security. The recovery process success ratio for the image dB 99.0, audio retrieval process was well proportioned. , We used Image metrics (PSNR), (SNR) and the inclusion ratio between the confidential letter and sound and cover (RMSE) between audio - stego and original sound. And high results were obtained about (85 - 95 )when recovery without any mention on the file (Stego_audio).

Abstract: Clustering texts organizes texts in subsets coherent and internally consistent, and different with each other. These subsets called clusters. The documents combines according to the similarity measures, that rely on features extracted of the documents. This technique applies in various fields such as web mining, search engines, and information retrieval. Clustering documents gives information retrieval, automatic extraction, and representation efficiently without user intervention for increasing growth of the new documents.This study aims to improve the accuracy and efficiency of arabic texts clustering. To achieve the aim of this study two approaches are used. The first approach uses the standard technique in Arabic texts clustering. The second approach is proposal to reduce features of the texts.The first approach is applied (K - medoids, K - means) and similarity measures (Euclidean, cosine). The problem of this approach is that huge of the features, which influence the efficiency and coherence of the clusters.The huge features for the documents adds challenge and lead to high dimension so coreference resolution technique approach is applied. This technique extracts main subjects for each document to improve arabic documents clustering in order to achieve the goal of our study. The system implements using a corpus contains on 200 sport news Arabic.Finally, evaluation measures are used including (Precision, Recall and F - measure) to evaluate our system, and we obtain acceptable results.First method exceed K - medoids and using similarity measures (Euclidean, Cosine) where highest values (0.60, 0.78, 0.67) of the method of k - means. In addition, the results of the proposed second way exceeds method of K - medoids and using similarity measures (Euclidean, Cosine) with coreference resolution, where the measures values (0.80, 0.83, 0.81).

After decades of Web's using , there were demands raised to restructure the web in order to allow machines do the work of the man on the web. So, the aim of this main generation idea is to enable machines .These machines could understand what they display by adding meaning to the traditional Web content, this is called the Semantic Web.The form of this meaning seems in a huge global database that has information connected to each other and understand by the machines. Therefore, the machines can be realized the relations between information, analysis and indexing of knowledge categories. All these which make the machines are responsible on main part of information research process, while the human's part is just to receive the results that are almost ready to benefit from them. Ontology notion seems to express a set of concepts within a particular field as well as the relationships between these concepts.In spite of the appearance of the Semantic Web, ontologies spread widely in various languages, but there was a shortage in Arabic language ontology within different areas. Even when it found, it was small attempts and unavailable on the linked data form in the web.This work aims to design an ontology that cares about the Arabic language and its components. So that this project focuses on these things : 1. Create a model for an Arabic Language Ontology, as follows : a. Identify the main concepts for the Arabic language like (noun, verb, letter, adjective and adverb) and their properties to form the structure of the ontology.b. Modeling the resulting ontology in one of modeling language .It has been used Object Role Modeling (ORM) because of its high strength to express and transform this model to the language The Web Ontology Language (OWL) .c. Verifying the ontology's components are logically connected and provide the right answers to the questions that are designed to by asking queries to it in SPARQL language.2. Populate ontology with individuals by - : a. Collect several instances from different sources and clarify their types by linking them to the main concepts of the Arabic language.b. Extract every meaning of the instances and linking them to the same meaning in the English language for the clarification .This is to indicate the possibility of using this ontology as dictionary bi - languages.That is one of its applications by linking it to other ontologies to reuse their information and exchange them.3. Sharing this ontology on WWW using Linked Data technology with free licenses.4. Creating a web page that contains Arabic - Arabic language dictionary in HTML and JavaScript languages .These were achieved by using the same words that included in the proposed ontology .All these give their meanings and types and be availableto the average user .5. The conclusion of this ontology is specifying many meanings to one word, however the ontology give us one type for specific meaning. That is considered negatives of the proposed work.Keywords : Semantic Web, Ontology, Ontology Population , Linked Data, ORM, OWL, SPARQL

Abstract: Email is a service for exchanged messages between group of people (sender and receiver) using communication network. Nowadays people, companies, and business sectors are using email in the official communications. There are a lot of threats on the email service and the most importantly one is the eavesdropping. Some email messages are very important and must have a level of security during exchange of them.The current study uses hash function to add data integrity by applying Secure Hash Algorithm - 1(SHA - 1). This study uses Elliptic Curve Digital Signature Algorithm to add authentication and non - repudiation to the email message sender.Encrypt of an email message is a solution to overcome the eavesdropping. Hence, the attacker can obtain the email message but cannot read it without the key. The encryption algorithm, which is used, is Elliptic Curve Cryptography. This algorithm has a strong encryption, high level of security, and small key size compared to the RSA algorithm.The contributions of this thesis are : proposes a new method based on genetic algorithm to select the most effective parameters of the Elliptic Curve Cryptography (a,b); and proposes four encryption methods : updated symmetric Elliptic Curve Cryptography, modified Menzes - Vanston Elliptic Curve Cryptography, hybrid symmetric and asymmetric Elliptic Curve Cryptography, and hybrid Menzes - Vanston Elliptic Curve Cryptography and AlGamal Elliptic Curve Cryptography.The proposed methods are compared against previous techniques. It is found that these methods outperform the previous techniques in terms of the encryption/decryption processing time and the level of security.
