An extraction-spectrophotometric technique has been applied and approved for the estimation of orphenadrine citrate in the presence of paracetamol in a binary synthetic mixture and in combined drugs. The procedure is built on the formation of a soluble red colour orphenadrine citrate – eriochrom black T (EBT) ion pair complex at pH 1.40, while the paractamol not paired. The produced red colour ion-pair complex was extracted with chloroform and showed maximum absorption at 509 nm. For quantitative evaluation Beer’s law applied to plot the absorbance against concentration, the relation was a linear in the concentration range of 0.10-6.00 µg/ mL with the molar absorptivity 4.4025 x104 L / mol. cm. The limit of detection and limit quantification were 0.024 µg/ mL, and 0.100 µg/ mL respectively. The intra-assay precision evaluated in terms of % relative standard deviation (RSD) (< 2%). And accuracy was validated with % recovery (98.8-102.5%). The results showed that orphenadrine citrate could be determined successfully in the combined tablet without interference by paracetamol and other common co-formulated substance.

Toxoplasma gondii is an opportunistic pathogen in which the reactivation of a latent infection can cause death in congenitally infected fetuses, newborns, and immunocompromised patients. This study aimed to determine the seropositivity of toxoplasmosis infection and the possible association with Interleukin-12 (IL-12) and Interleukin-23 (IL-23) cytokines in breast cancer patients. In this study, 190 women were enrolled. All serum samples were tested for T. gondii immunoglobulins (IgG and IgM) antibodies and (IL-12, IL-23) levels using ELISA technique. The result of this study showed that breast cancer patients recorded the highest percentage of toxoplasmosis infection. There were no positivity rates for anti- Toxoplasma IgM in breast cancer patients while the positivity percentage for anti- Toxoplasma IgM among the control group was (7.00%). Furthermore, the seroprevalence of anti- Toxoplasma IgG was the highest in the age group (31- 40) years in patients with breast cancer while the highest mean titer of the IL-12 is restricted to ages (21-30) years in the control groups who are seropositive to anti- Toxoplasma IgG. Although, in patients with breast cancer who are seropositive to anti- Toxoplasma IgG, the highest mean titer of the IL-23 was in ages (21-30) years. Since most immunosuppressive patients are exposed to various possible risk factors including Toxoplasma primary infection or reactivation, so it is important to diagnose and treat toxoplasmosis in breast cancer patients to reduce the consequences of the infection.

leishmaniasis is a disease of global concern, Leishmania types and distribution rates vary from country to another. For visceral leishmaniasis serum samples were examined by the kala-azar dipstick rapid test. Meanwhile smears were taken from lesions, air dried, fixed and Leishman stained then microscopically examined for amstigote stage in cutaneous leishmaniasis. From April 2014 to April 2015, 150 samples for cutaneous leishmaniasis (CL) and 108 serum sample for visceral leishmaniasis (VL) from in and out patients in Pediatric, Azadi Teaching and Kirkuk General Hospitals were examined. The incidence of visceral leishmaniasis was very low (2.7%) comparing to that in cutaneous leishmaniasis (64.6%). No significant differences had appeared between the cutaneous leishmaniasis incidence in male or female. The most age group infected with cutaneous leishmaniasis in both genders was 5 ≤ years old, with rate of 26.1% in male and a rate of 15.8% in female. Significantly high frequency of the patients were presented with only one or two lesions with rate of 39.17, 25.7 % for each type of lesions respectively. The most location that infected with CL was hand (27.7%) and high rate of them being moist type (71.13%). In Kirkuk city CL is more prevalent than VL. High rate of CL is moist type locating in the limbs and face. The infection is more frequent in children than in adult. For CL a smear taken from the lesion is much worthy than a lesion blood sample or re aspirated saline injected to the lesion.

The resistance of Staphylococcus aureus to ciprofloxacin has complicated the problem of treating staphylococcal associated infections in which MRSA is the causative agent since ciprofloxacin was the drug of choice to treat such infections. Our study investigated the incidence of Ciprofloxacin resistant S. aureus isolates that were also methicillin resistant among Iraqi patients. The obtained bacterial isolates were tested for Ciprofloxacin resistance using agar dilution method and the sequence of gyrA and parC. The results revealed that about 8% of the isolated MRSA strains were Ciprofloxacin resistant and the resistance was due to mutation in gyrA rather than parC.

In this work, has been a studied the effect of thermal treatment using different annealing temperatures (373, 423 and 473) K in vacuum on structural and morphological properties of organic semiconductor Alq3:C60 thin films which are prepared by the spin coating on a glass, silicon and porous silicon. These films have been coated on substrates with speed of 2000 rpm. The structure properties of Tris(8-hydroxyquinoline) aluminum (III) (Alq3) and fullerene (C60) (100:1) and (100:10) blend as-deposited and treated have been studied by X-ray diffraction (XRD) for glass only and morphological properties by Atomic Force Microscope (AFM) for silicon and porous silicon substrates. The results of XRD pattern shows that the structure of (Alq3:C60) as-deposited and annealed thin films are polycrystalline in nature for both mixed weight ratio. The result of AFM measurements show that grain size increase is due to the increases of surface energy at high temperature. Surface roughness increasing and decreased randomly with the temperature can be attributed to the random distributions of the grains and also due to the phase change.

An integrated seismic sequence stratigraphy and facies analysis has been carried out with a view to understanding the depositional environment and stratal stacking pattern of Nandy Field of Niger Delta. Well logs and biostratigraphic information were used to identify the lithologies, stratal stacking patterns, stratigraphic surfaces, system tracts and reservoir potentials of the field. Seismic sequence stratigraphy and seismic reflection patterns were used to identify the seismic facies. Facies-related attributes were employed to identify the continuity and amplitude of seismic events. Three seismic facies packages and three reservoir sands were identified. The environments of deposition of the area consist of marginal marine to continental depositional settings predominantly made of shoreface deposits with few channel sands. The depositional model of the area shows that the deposition went down the axis of fluvial depositional system, which transports sediments through channels down to the shelf into the base of the slope down the basin. The seismic reflection patterns in this field are parallel to divergent reflections, high-continuity and high-amplitude facies, low-amplitude facies, low-continuity and variable-amplitude reflections, chaotic reflections and wavy reflection patterns. The seismic stratigraphic analysis of this field revealed the presence of low stand system tract (LST), high stand system tract (HST) and transgressive system tract (TST). Sands 1 and 2 were delineated within high stand systems tract (HST) while sand 3 was within low stand systems tract (LST). The results of this study show that the Nandy Field was of high hydrocarbon potentials and highlight the importance of using seismic reflection parameters (reflection configuration, amplitude, frequency and continuity) in the division and classification of seismic facies.

Urban Samarra City is characterized by high population density and wide variation in land use, has led to many environmental problems, for this purpose the environmental assessment became an urgent need for surface and ground water at study area. Three water samples from Tigris River and six groundwater samples were collected and analyzed for heavy metals as Fe, Mn, Zn, Cd, Cu, Co ,Pb, Ni, Cr, As, Mo, Hg, Al, Li, Be, Se, V, U, Sr. Most heavy metal concentrations have shown higher level than standards, such as Fe, Mn, Cd, Pb, Ni, Cr, As, Mo, Hg, Al ,Li ,Be, Se, V, that might be due to anthropogenic activities such as agricultural and the heavy use of fertilizers, besides other activities among them industrial .
All water samples have higher concentration level of Uranium except (SW1, SW2, SW3, GW1) might be due to military activity. On the other hand all samples were polluted in Co except SW2, GW4, high value of Co may be caused by industrial processes and oil product spills.
Physical and chemical properties values which have obtained in this study are pH, EC, TDS, TSS, DO, BOD,COD and turbidity. Water analyses reveal unacceptable values for physical and chemical parameters according to WHO standard and IQS2009 limits for drinking water, BOD, EC have shown high values in all surface and groundwater samples. Whereas, high values of TDS, COD and turbidity only in ground water samples.
The water is not drinkable according to Water Quality Index (WQI) all values are above 100 and, in the sequence (GW1>GW5>GW4>GW3>GW6>GW2), the water quality index of surface water (SW3>SW2>SW1). Mixing of the shallow groundwater and Tigris River water show various patterns affected by other factors such as the aquifer recharge and evaporation, especially at the shallowest parts.

Steganography is a useful technique that helps in securing data in communication using different data carriers like audio, video, image and text. The most popular type of steganography is image steganography. It mostly uses least significant bit (LSB) technique to hide the data but the probability of detecting the hidden data using this technique is high. RGB is a color model which uses LSB to hide the data in three color channels, where each pixel is represented by three bytes to indicate the intensity of red, green and blue in that pixel. In this paper, steganography based RGB image is proposed which depends on genetic algorithm (GA). GA is used to generate random key that represents the best ordering of secret (image/text) blocks to be hiding in the cover image. Experimental results, obtained from different experimental tests, show that our proposed system proves to be more efficient than another steganography technique presented in literature and in comparison with the original cover image in terms of fidelity criteria and degradation quality of the stego_image
