Abstract

Objective of this research to obtain bacteria Streptomyces that have high-efficiency in the decomposition of hydrocarbon waste. Samples of soil were taken from different area with high pollution, like Ramadi, Baiji and Daura. We have obtained 9 isolates of bacteria Streptomyces the results showed that the isolate Streptomyces spp M3 have high-efficiency in the decomposition of hydrocarbons residues, so we have studied the morphological and physiological characters of this isolate by studying some Biochemical tests and its ability to decompose the hydrocarbon wastes through growth on liquid culture media containing hydrocarbon wastes as Carbon source , we were found that it has high capacity to have a high decomposition for hydrocarbons when grow in the test culture media 4 containing 6 ml of the hydrocarbon residue and 1 g of starch as a Carbone source, and were able to grow very well in the test media 2,3,5,6 and 7 that containing hydrocarbons residues as carbon source, also able to grow in the test media 10 that containing 15 ml of hydrocarbons only as a Carbone source. We conclude that this isolate can be use to decrease the pollution caused by hydrocarbons residues because it has high ability to utilized these residues as carbon source.

Abstract

A total of 136 urine samples were collected aseptically from patients with urinary tract abnormality from April to June, 2010. Depending on morphological, cultural and biochemical testes 16(~11.8%) Proteus mirabilis isolates were recovered. They were examined for antibiotic resistance. All of the isolates(100%) were resistant to Ampicillin, Amoxicillin, Cephalothin, They showed highly resistant rate to Tetracycline (81%), and Gentamycin(75%). Some of the isolates exhibit resistant to the third generation Cephalosporines as Cefotaxime and Ceftriaxon(Cef). There are 5 Multi drug resistant (MDR) phenotypes have been recognized. It have been found that three of these isolates produced β-lactamase enzymes and each of them was bearing single plasmid of more than 3000bp in size (the largest fragment of the DNA marker). Following curing experiment, the mutant strains lost their plasmids and resistance to all β-lactam antibiotics which included Ampicillin, amoxicillin, cephalothin, cefotaxime and ceftriaxone as well as Tetracycline and Gentamycin. The results of present study highlight that some of MDR phenotype exhibiting by uropathogenic Proteus mirabilis attributed to plasmid bearing multiple resistance determinant.

Abstract

The Petrography and Heavy mineral study of Walash-Naopurdan Series Sandstone (Middle-Late Eocene) at Qalander area is carried out. Thin section study of twenty seven samples showed that these sandstones consist of quartz, feldspar, rock fragments (lithics), matrix, and cement. The rock fragments are of sedimentary, igneous, and metamorphic types as an indication of multiple source rocks originated from the complex thrust zone of northeastern Iraq. The Heavy mineral analysis also showed different types, dominated by opaques and transparent minerals as a further indication of multiple source rocks. The main constituents of the studied sandstones (quartz, feldspar, rock fragment and matrix) are used in their classification which showed that the sandstones are of lithic greywacke type.The provenance indicating triangular diagrams (QtFL and QmFLt) showed that the Walash-Naopurdan Series Sandstone is of recycled orogen sources shared between transitional, mixed, dissected and transitional arcs tectonic settings. These represent a complex convergent boundary with dissected transitional volcanic arc which was subjected to uplift and erosion.

Abstract

This thesis deals with studying the effect of salts Solutions washing on the characteristics of expansive soil. The expansive soil was brought from three areas of Mosul city (The Yarmouk district, University of Mosul, and AL- Kasak). It emerged from the tests that the soils swelling properties are medium to high depend on clay contents. Where the results of the mineral analysis by X-ray diffraction device showed that the soils have the clay minerals: Montmorillonite, Kaolinite, Illite, Chlorite, and Palygorskite. But there is difference in the proportions of (quantity) clay minerals. Three types of salts solutions are used in the washing, {Sodium Chloride (NaCl), Potassium Chloride (KCl), and Calcium Chloride (CaCl2)}. To determine the effect of the washing for each ion on the index and swelling properties of the chosen soils sample, solutions were prepared at rates (1%, 3%, and 5%) in form of weight percentage, and three times washing for each rate. The results showed a decrease in the amount of liquidity limit and the plasticity index of the soils in the first wash by salts solutions. with as increasing the rate and number of washing it obtained change (low and high) in the amount of liquidity limit and plasticity index of soils. Also the results showed that the rate of reduction in the plasticity index of soils that washed by potassium chloride was the highest than soils that washed by sodium chloride and calcium chloride. And the optimum effect rates of washing by salts solution on the plasticity index are 3% of Potassium Chloride in the third wash for Yarmouk soil (clayey low plasticity soil ), 5% of Potassium Chloride in the second wash for University soil (clayey high plasticity soil), and 1% of Potassium Chloride in the third wash for AL- Kasak soil (clayey high plasticity soil). The results indicated that the first wash effect of salts solutions in the swelling properties of the soils that compacted at Optimum Moisture Content (OMC) and Maximum Dry Density (gd max) taken from the Modified compaction curve, led to a reduction in the values of swelling properties as an increase in washing rate by salts solution. The results showed a reduction in the swelling properties in the first wash of the Yarmouk soil by potassium chloride at higher rate than using solution of sodium chloride and calcium. Also the results showed a reduction in the swelling properties in the first wash of the University and AL Kasak soils by calcium chloride at higher rate than using solution of potassium chloride and sodium. And the multiple wash led to change (low and high) in the swelling properties. The optimum effect rates of washing by salts solution on the swelling properties are 5% of Potassium Chloride in the first wash for Yarmouk soil (clayey low plasticity soil), 5% of Calcium Chloride in the first wash for University soil (clayey high plasticity soil), 5% Calcium Chloride in the third wash for AL- Kasak soil (clayey high plasticity soil).

Abstract

Theoretical and experimental study of heat transfer by forced convection from the cylinder in cross flow embedded in a saturated porous media was carried out. The theoretical part of the work includes the derivation of the governing momentum and energy equation by using Darcy flow model. The two equations are solved by finite difference method with constant cylinder surface temperature, with a Peclet numbers ranged between (1< Pe<10 ). The experimental part of this work included the construction of an experimental model composed of cupper cylinder with a (13 mm) in diameter heated internally by an electrical source. The cylinder was embedded in a packing of glass spheres with diameter 12 mm placed in a low velocity wind tunnel. Both the theoretical and the experimental results revealed that the average heat transfer increased when the Peclet number increased.
