Genetic basis of recurrent abortion is poorly understood, Single gene mutations, polygenic, and cytogenetic factors are all found to show association with recurrent abortion. The analysis of single nucleotide polymorphisms in the genes coding for enzymes which responsible for regulatory of metabolic pathways (e.g. methylene tetra hydrofolate reductase), clotting factors (Factor V leiden and prothrombin) and hormones and hormone receptors (progesterone receptor). This study included (85) pregnant women who suffer from problems during pregnancy and the age range was between (25-35) years. The samples were divided into four groups ,the first included pregnant women who suffer from recurrent spontaneous abortion , while the second included pregnant women with missed abortion , the third group included pregnant women with recurrent spontaneous abortion and positive TORCH examination and the final group was considered a control group. The result of the study showed a relationship between cases of pregnancy disorder and genetic mutations of MTHFR gene at the (A1298C) site, the result of the study for a group of women with RSA showed that the distribution of the mutant genotype CC was the highest 40% and the repetitive alleles for this group was 57.5% for mutant allele C and 42.5% for normal allele A. Also the group of missed abortion showed that the distribution of the mutant genotype CC was the highest 40% and the repetitive alleles for this group was 52.5% for mutant allele C and 47.5% for normal allele A. Whereas the group of women with positive TORCH showed that the distribution of heterozygous genotype was the highest 50% and the repetitive alleles for this group was 32.2% for mutant allele C and 67.8% for normal allele A.

There is a growing need to produce asphalt materials with high economic feasibility, that is the production of asphalt materials with rheological properties that differ from the base asphalt (unmodified asphalt), can be used in many fields such as the production of paving asphalt, where it is not appropriate to use ordinary asphalt. This study included the modification of the rheological properties of Daura asphalt by catalytic chemical treatment with thermoplastic polyurethane (Used in the interior parts of cars) using a microwave oven at a power of (360) watts and at different periods of time. As well as treat asphalt samples with the thermoplastic polyurethane in the presence of sulfur. The modified asphalt samples were studied in terms of ductility, penetration, softening point and penetration Index. A sample with good rheological specification was selected (As7) that are conform with the specifications of Iraqi Roads and Bridges Authority, The selected sample were studied in terms of conducting Marshall tests and comparing them with the original sample in order to demonstrate the possibility of using the modified sample as an paving asphalt. The obtained results showed good specifications in terms of crawl and stability values. An aging test was also conducted on the sample (As7) of the good rheological specifications.

The chemical constituentisof three types of bituminous materials found in different conditions in Mishraq sulfur Minewas studied. The FTIR spectroscopy showed reduce in the length of hydrocarbon chains from the intensity of paraffinic bands in bitumenous materials of Frasch sulfur Mine (BM) compare with natural bituminous materials (NB) and Bituminous materials which extracted in-depth about 200 m without exposing to Frasch process condition (BB). The percentage of asphaltene in (MB) which increases dramatically is found 63.64% compared with (BB) and (NB) which 37.37% and 14.28% respectively and a similar decrease in percentage petrolene (maltene) . A percentage of n-hexane fraction by silica gel chromatography of petrolene (MB) is 18.49% compared with (BB and N.B) are 25.06 % and 47.05 % respectively while the cyclohexane fractions of petrolene MB are four-time of N.B and three-time of B.B . From all results, we conclude that a reaction has occurred between sulfur and bitumenous materials especially hydrocarbon chains of Aromatics and naphthenic rings in sulfur well during Frasch process which leads to an increase in asphaltene percentage and decrease of petrolene.

A high voltage pulse generator was development and implemented. This generator has the capacity to generate a sequence of pulses with a varying pulse height from 0 to 5 kV, and changes the pulse width in ms range. This generator has been tested and used to study the pulse glow discharge in argon by using the capillary tube under pressure 0.3 to 0.5 torr. This study has succeeded to establish the nature of discharge relaxation (plasma relaxation) when a high voltage pulse causes a breakdown in the gas (converts to conducting case).The current decays when the obtained voltage pulse is switched off. The electronic switching is a successful tool which can be used to generate high voltage pulses with flexibility that help to adjust an adjustable peak height voltage pulse, pulse duration and pulse width. The plasma returns to a neutral status when the current decay time is less than plasma relaxation time. This mean that if plasma decays time is more than relaxation time the plasma will transit from pulse glow discharge to continuous discharge. In this study the currentvoltage characteristics in relation to different gas pressures were in the abnormal glow discharge regime.

A spectrophotometric method has been developed for the determination of aminophenol isomers (o-aminophenol, m-aminophenol and p-aminophenol). The method is based on oxidative coupling reaction of these compounds with 4-aminoantipyrine (4-AAP) in the presence of cupper sulphate as oxidizing agent in alkaine medium forming a reddish brown colour. The products show maximum absorption at 440 nm, 480 nm and 445 nm for o-aminophenol, m-aminophenol and p-aminophenol respectively. The molar absorptivities are 8.632×10 ,9.33×10 and 9.1449 ×10 l.mol.cm for concentrations obeyed Beer’s law in the range 1-20, 1-24 and 1-7 μg.ml for the above compounds respectively. The average recovery was ranged between 98.38% and 101.01% with relative standard deviation < 1.6 for all the studied compounds. The 4-AAP products were formed in the ratio of 1:2 aminophenol isomers : 4-AAP. The stability constant of the products was 7.4 ×10, 3.27×10 and 9.94×10 l.mol for o-aminophenol, m-aminophenol and p-aminophenol products respectively indicating the good stability of these products.
