المستخلص: Aim of study was to evaluated the effects of propylthiouracil (Ptu) drug on both maternal and fetus rats, used experimental animals (Rattus norvegicus) and after housing, breeding and adapting, (50) of virgin females choosen, isolated and then divided into two groups each group contain (25)rats, The mean weight of the animals was(200 ±50) gm and (8 - 10) week of age. Females on first group regarded as control and treated with distilled water while animals in second group were treated with (Ptu)dose as (0.05 %) and left for(14.5, 16.5, 18.5, 20.5, 21.5)for each group. Macroscopic observations on each group were recorded including changes in thyroid gland morphology, hypertrophy and enlargement at each period (14.5, 16.5, 18.5, 20.5, 21.5) days of gestation for both pregnant rats and embryos,the shape of uterine hornes,and uterus with changes of fetus number, resorption, atrophy, malformation of body parts, indifferentiation of fore and hind limbs, skin abnormalities were noticed. The changes in placenta which appeared irregular, pale colour, congested with white fibrous regions were noticed in hypothyroid rat comparing with placenta of control group animal, which looked red, discoid shape and normal surface without any abnormal signs, in addition fatty ovaries with large amount of adipose tissue was accumulated in abdomen cavity, the ovaries irregular and showed structures in most pregnant rats of hypothyroid group comparing with control pregnant females.Present showed significant decreased at (P≤0.05) in mean length, weight and number of fetus at (14.5, 16.5, 18.5, 20.5, 21.5) days of gestation in all embryos related to hypothyroid rats compared to control. Histological study with light microscopy on sections from thyroid gland related to rats with induced hypothyroid showed reduced, small follicles with empty or little colloid substance, each follicle lining simple cuboidal or flat epithelium, an increased with stroma, variable size of follicles most of them smaller compared to control thyroid gland from control rats, which showed normal lobules, large follicles filled with colloid, and poorly stroma.Sections from uterus, ovaries, oviduct related to hypothyroid rats showed variable histological changes ranged from mild to severe like abnormal reduced layers of uterus, irregular uteri folded, degenerated with simple epithelial tissue that lining the uterus villi, haemorrhage in uterine gland, deposition of collagenous fibers, infiltration of lymphocytes and accumulation of adipose tissue. Ovaries from hypothyroid rats showed variable changes with ovaries follicles maturation, accumulated of adipose tissue, decreased graffian follicles, infiltration of lymphocytes and deposition of collagenous fibres with degenerated of lining epithelial layer compared with control ovaries.Microscopic observations of placenta sections from hypothyroid rats at different period of gestation revealed loss tissue, reduced placental layers thickness, necrosis in the peripheral regions, degenerated cytotrophoblasts that surrounding capillaries, the trophoblast giant cells appeared with degenerative changes in labyrinth and spongiotrophoblasts regions. undifferentiated fetal blood capillaries compared to control which the sections have normal structure differentiated to decidual basalis and labyrinth zones, the junctional zone composed of outer giant cells that separated the decidua basalis and trophospongium.In this study the ultrastructural changes in thyroid gland from maternal and fetus related to hypothyroid rat at (14.5, 16.5, 18.5, 20.5, 21.5) days of gestation were identified by electron microscopy and included changes in apical cytoplasm of follicular cells to microvilli, blebs and protrusions also dilated rough endoplasmic reticulum, increased lysosomes, the empty vacuoles more than the dense vesicles, increased mitochondria and Golgi apparatus cisternae, changes chromatin and more cellular debris. Biochemical results in thyroid hormones revealed to significant increase in mean concentration of (TSH) in pregnant females with hypothyroidism during gestation periods in compared with control group, also there was an decrease in both (T3, T4) non significant, significant increased concentration in serum of pregnant rats on treated group with (Ptu) compared with their concentration of control pregnant rats.Levels of some oxidative enzymes (GSH & MDA) was estimated in this study and there was significant increased,non significant in their concentrations in serums of rats with induced hypothyroidism comparid to control group during each period of gestation (14.5, 16.5, 18.5, 20.5, 21.5) day. The study determined some of haematological parameters such as (R.B.Cs) count, (H.b) level and (P.C.V) ratio which showed non significant at (P≤0.05) hypothyroidism rats compared with control rats at the same period of gestation. Also the results revealed non significant with (T.L.C), (D.L.C) in all pregnant rats with hypothyroidism compared to control rats, the data showed an increased with lymphocytes and Neutrophils and Esoinphils cells in smears prepared from hypothyroidism rats compared to control group

المستخلص: The present study was conducted to evaluate the effect of different concentrations of the growth regulators 2, 4 - D; Dicamba and NAA on the induction of date palm (Phoenix dactylifera L.) primary callus Hillawii cv., by analyzing morphological, biochemical; anatomical and molecular responses. Three concentration of 2, 4 - D (10; 50 and 100 mg/L), Dicamba (1; 5 and 10 mg/L) and 30 mg/L of NAA were examined during the course of this study. in addition, several antimicrobial agents were selected to evaluate their morphological and biochemical impacts on the primary callus of date palm including the antibiotics (Gentamycin 50 mg/L and Chloramphenicol 50 and 100 mg/L), as well as, the fungicides (Switch 1 g/L and Beltanol 1 ml/L), After induction of the primary callus from each treatments, the following results were obtained : 1. The results showed that the treatments with 2, 4 - D at 10 mg/L and Dicamba at 1 and 5 mg/L did not stimulate any callus growth over the time of incubation on MS medium.2. It was evident that the treatments of different growth regulators have a significant effect on the initial period (day) for callus initiation, the shortest period have been obtained with the low concentration of 2, 4 - D (50 mg/L) and Dicamba (10 mg/L) which were 67.57 and 66.75 days, respectively, while the high concentration of 2, 4 - D (100 mg/L) led to increase this period significantly up to 120 days.3. Both fresh and dry weight of date palm primary callus decreased significantly at the treatment of high concentration of 2, 4 - D (100 mg/L) up to two folds compared to the treatment at low concentration of 2, 4 - D (50 mg/L), similar trend of results were found with browning percentage and intensity.4. Biochemical analysis of produced date palm primary callus revealed that the high concentration of 2, 4 - D (100 mg/L) led to a significant increase in the total content of carbohydrates; Proline, Peroxidase activity and Phenolic compounds which considered as a stress indicators, and another decrease of total soluble proteins and free amino acids was accompanied with this treatment compared to the same growth regulator at low concentration and Dicamba treatments.5. Anatomical study revealed that asignificant damage was caused by the high concentration of 2, 4 - D (100 mg/L) on date palm primary callus, this damage was evident from the abundant and distribution of tannins compounds across the primary callus tissues, thus, was accompanied with high percent of browning, compared with the treatments of 2, 4 - D at low concentration, Dicamba and NAA.6. The analysis of Protein profile revealed the similarity between the patterns of control treatment (juvenile leaf of Hillawii cv.) and 2, 4 - D at low concentration, as well as, Dicamba. Similarity indices results for protein profile of date palm primary callus proved the genetic similarity of 100% between control treatment and both 2, 4 - D (50 mg/L) and Dicamba ones, while, the lowest similarity percentage was observed with high concentration of 2, 4 - D (100 mg/L).7. The results of RAPD marker analysis of the extracted genomic DNA form date palm primary callus using four deca oligonucleotide primers showed the efficiency of three primers (OPAR3; OPAR8 and P.650) in their amplification of examined DNA,. RAPD profile revealed an identical matching between control treatment and 2, 4 - D at low concentration, followed by Dicamba and NAA auxins, while, the increasing in 2, 4 - D concentration up to 100 mg/L led to disappearance and the appearance of new DNA bands compared to control treatment, with a highest genetic distance among other treatments.Similarity coefficient analysis showed that the highest genetic similarities were found between control treatment and 2, 4 - D (50 mg/L) with similarity index of 96% , followed by Dicamba and NAA treatments with indices of 74 and 66%, respectively, the lowest similarity index was obtained between control and 2, 4 - D at high concentration which was 27%.8. The screening results of antimicrobial agents showed that the treatment with Switch fungicide (1 g/L) and Gentamycin antibiotic ( 50 mg/L) did not stimulate any callus growth over the time of incubation on MS medium supplemented with either 2, 4 - D or Dicamba.9. Beltanol fungicides (1 ml/L) treatment had a negative effect on the initiated primary callus either by 2, 4 - D or Dicamba, its treatment led to a high significant reduction in total solubleprotein and free amino acid content compared to control results, while an increase of total carbohydrates, Phenolic compounds, Proline and Peroxidase activity was detected with Beltanol fungicide.10. The Chloramphenicol treatment at low concentration (50 mg/L) showed positive results on the growth of primary callus at 2, 4 - D or Dicamba auxins according to morphological and biochemical analysis.

Their growth rates and biodegradation ability were investigated in mineral salt media supplemented with light Remella crude oil. These strains consist of Streptomyces variabilis 7525, Streptomyces variabilis 5W75, Streptomyces cellulosae XFB - T, Streptomyces parvus S86, Streptomyces bacillaris S4BW2, Streptomyces flavoviridis VITHM - 1 and Nocardiopsis synnemataformans ITD - 3, that the sequence identity range from 99% to 100%. Our study find a new actinomycetes strains isolated from contaminated soil. these strains appears different capacity on the degradation of crude oil in mineral salt media , the highest was found to vary from 50.2% to 72.4%.The effect of the cultivation factors (temperature, pH, and concentration of crude oil and trace elements ) on growth of the actinomycetes strains and crude oil degradation was evaluated. The highest cell growth and the amount of crude oil degraded 80% were observed in optimized cultivation conditions (30oC and initial pH 7) after 10 days, this ratio reached to 85% by addition of trace elements solution at same condition by S. cellulosae XFB - T.The biodegradation test lasted 60 days in soil by actinomycetes strains at different factors shown the highest of the crude oil was removed in experiment that inoculums with 10ml of each bacterial strain, value 87% by Streptomyces bacillaris S4BW2 at 30oC. Bioremediation is an efficient strategy for cleaning up sites contaminated by hydrocarbons. Microorganism of soil is affected by hydrocarbon disturbance thus selective enrichment of hydrocarbon utilizers occurs. The technology is very effective in dealing with petroleum hydrocarbon contamination. Hydrocarbons react with the soil matrix and microorganisms determining the fate of the contaminants relative to their chemical nature and microbial degradative capabilities. The potential effects of sawdust, and mixture of cow and sheep dung as amendment nutrient supplements to biostimulate autochthonous microflora and augmentation for hydrocarbon bioremediation were investigated in test biopile and bioreactor. The soil was ground and fluffed by admixture of 1.5% sawdust, then supplemented with the necessary minerals and watered to provide conditions favoring microorganism growth industrial aeration was provided in pile by system of a abundant perforated drainage - pip network to simulate bioremediation treatments through a 90 - day period. During this period, we monitored total petroleum hydrocarbons (TPHs) and n - alkanes degradation and changes in bacterial communities. The (TPHs) had been reduced from 52 to 10.6 g/kg (79.6 %), the rate of Biostimulants Efficiency (BE) was (71.4%) in biopile and from 52 to 13.5 g/kg (63.5 %) in bioreactor . In soil, the dominant microorganism population comprised Gram - positive bacteria from actinomycete group and autochthonous microorganisms which decompose hydrocarbons reached highest level 2 x 107 and to 1.1 x 107 CFU/g at 45 days in biopile and bioreactor respectively . Based on these data, the study conclude that is ex situ ( Biopile and bioreactor ) experiment the best strategy, inexpensive, efficient, and environmentally friendly and may thus offer a viable choice for petroleum hydrocarbons - contaminated soil remediation.

المستخلص: The research included synthesis ,characterization and evaluation of new corrosion inhibitors(bis(2 - hydroxy ethyl) thioterphthalte and bis(2 - hydroxyethyl)terephthalate 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, catalyst , the equivalent weight of reactants and others. The synthesized corrosion inhibitors were characterized by FTIR spectroscopy . The two inhibitors were evaluated as corrosion inhibitors using sulfuric acid as corrosion media for carbon steel( 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, 308,318,328 K) were used to calculate many factors that determined the efficiency of the inhibitor like corrosion rate , charge transfer resistance and inhibitor efficiency. it was observed that the corrosion rate and charge transfer of the carbon steel for the inhibitors 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 (96%) for the bis(2 - hydroxy ethyl) thioterphthalate for the 24ppm and (91%) for the bis (2 - hydroxy ethyl) terephthalate for the 25ppm .Many thermodynamics functions was calculated ,activation energy a ,entropy S , enthalpy  and free energy G 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 G data the type of adsorption was chemical because the value of Gads was higher than (20 KJ/mol) .

المستخلص: In this study, two types of Schiff base were prepared as ligands L1, L2, by reaction of an equal number of moles of tris(hydroxymethyl) methyl amine with salysildehyde and vanillin in a methanolL1 : ((E) - 2 - ((2 - hydroxybenzylidene) amino) - 2 - (hydroxymethyl) propane - 1,3 - diol) L2 : ((E) - 2 - ((4 - hydroxy - 3 - methoxybenzylidene) amino) - 2 - (hydroxymethyl) propane - 1,3 - diol).The Cu(II) and Mo(VI) complexes were prepared to produce the : - A1 : tetrakis(μ3 - 2 - {[1,1 - bis(hydroxymethyl) - 2 - oxidoethyl] iminomethyl} - phenolato) tetrakis [aqua copper(II)].A2 : tetrakis(μ3 - 2 - {[1,1 - bis(hydroxymethyl) - 2 - oxidoethyl] iminomethyl} - 2 - meth - oxy} - phenolato) tetrakis [aqua copper(II)].B1 : (E) - 2 - methyl - 2 - ((2 - ((methyl(l1 - oxidanyl) dioxomolybdenio) oxy) benzylidene) amino) propane - 1,3 - diol).B2 : (E) - 2 - ((4 - hydroxy - 3 - ((methyl(l1 - oxidanyl) dioxomolybdenio) (methylene) - l4 - oxidanyl) benzylidene) amino) - 2 - methyl) propane - 1,3 - diol).The ligands and complexes were characterized by Fouries transformer infrared FTIR, UV and NMR techniques.All these techniques insisted that the ligands and their complexes were prepared successfully.On the other hand, the four complexes A1, B1, A2 and B2 were evaluated as corrosion inhibitors against a corrosive environment of 0.1M of hydrochloric acid at constant temperature of 25°C and different concentration for each one of the above complexesIIrange (10 - 50) ppm and it has been found that the efficiency of inhibition at a temperature 25℃ are not highly efficient, the KI was added in order to increase the efficiency of these inhibitors values to these inhibitors.The inhibition efficiency for all inhibitors was increased in presence of KI compared with the absence of it.On the other hand, the complexes of copper i.e., A1 and A2 have higher efficiency than molybdenum complexes i.e. (B1 and B2) this can be attributed to the ability of copper ion (II) to donate the electron density to the ligand by back donation competence these behaviour compared with molybdenum ion (VI) that has not the ability that present in copper ion, Also studied the effect of concentration of the inhibitor prepared in other temperatures change separately and these grades are within the range (35 - 55) ℃ has been observed that efficiency does not increase either the existence of KI with the inhibitor, or without, but the decreasing efficiency with increasing temperature, means that the inhibitor adsorbed physically on carbon steel alloy.The functions thermodynamic adsorption such as free energy, enthalpy and entropy were studies depending on the adsorbent layer θ on the surface of the carbon steel alloy. The data was shown all the complexes are subject to model for Langmuir adsorption was shows the free energy negative values means that the interaction is spontaneous and notes total increasing of the temperature less than the negative value of the free energy leading to towards the is non - spontaneous. The negative values of enthalpy means that the interaction is exothermic, the negative value of the entropy of adsorption ΔSads and gradually moving toward positive values with a high temperature means that the random was less in high temperature. Also the kinetics of corrosion in the absence and present of the inhibitor was studied with KI in (0.1) M HCl. The activation energy and other thermodynamic function such as enthalpy and entropy and free energy was shown that the higher activation energy in presence inhibitor and it was higher in presence of KI with inhibitor. This is an indication that the interaction of corrosion is small in the presence of these inhibitors.

المستخلص: 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).

المستخلص: 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 .

المستخلص: 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

المستخلص: 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.

المستخلص: جرى قياس ودراسة التوصيلات الكهربائية عند الترددات الواطئة للمحاليل المائية من املاح الاديبات المحضرة بطريقتين : احداهما كيميائية لايونات المغنسيوم والباريوم والكوبلت والنحاس والنيكل والزنك (الخارصين) , والاخرى (ولاول مرة) كهربائية لخمسة منها عند درجات حرارية مختلفة ضمن المدى من 298.15 K وحتى 313.15 K باستعمال جهاز قياس التوصيلية (Conductivity meter) . اجريت التحاليل المتعلقة بنتائج التوصيـــــــلية الكهربائية بطريقة تقنية التقلــــــــيل للحد الادنى (Minimization) باستعمال اربع مــــــــــعادلات نظرية للتوصـــــــيلية وهي مـــــــــعادلات (Fuoss - Hsia وPitts) الموسعة والمحددة . اوضحت النتائج التحليلية للاملاح المستعملة انها جميعا لا تتصرف كالكتروليتات "قوية" وان تفككها ليس بالتفكك التام . كما بينت تلك النتائج ان التوصيلية الكهربائية المنخفضة غير الاعتيادية لتلك الالكتروليتات لا تعزى الى وجود الجزيئات المتعادلة كهربائيا ولكن تعزى الى تكوين مزدوجات الايونات (Ion - Pairs) . كما جرى حساب قيم حاصل فالدن فضلا عن استحصال قيم الدوال الديناميكية الحرارية القياسية (∆H˚ و∆S˚ و∆G˚) لعملية التجمع الايوني عند مختلف درجات الحرارة المشار لها اعلاه بوساطة اعتماد كل من ˳Λ وKA على درجة الحرارة . واخيرا جرى تدوين ومناقشة جميع النتائج المستحصلة . اختبرت الثباتية الحرارية لمادة PVC باستعمال جميع الاملاح واعطت نتائج ايجابيه بهذا الصدد ،اذ مزجت مع PVC بنسب وتم قياس TGA للمزيج . | The audio electrical conductances of aqueous solutions of magnesium, barium , cobalt , copper , nickel and zinc adipate have been measured at various temperatures in the range of 298.15 K to 313.15 K , using an audio frequency conductance bridge. 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

المستخلص: 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
