Abstract

Twenty clinical and fecal samples (ten clinical samples from patients attending to Imam Ali Hospital and ten chicken faeces samples collected from local poultry farm in Baghdad city) collected during December 2015, for isolated Klebsiella pneumoniae. All K. pneumoniae isolates were extended-spectrum β- lactamase producers and biofilm formation. The activities of two selected K. pneumoniae isolates for their biofilm formation and susceptibility to antibiotics after treatment with several plants extracts were investigated. The results of water and 60% ethanol extracts for Matricaria chamomile flowers, Alhagi maurorum leafs, Syzygium aromaticum buds (clove) and Arctium minus leafs were showed reduction of biofilm formation and change the ability of antibiotic susceptibility for these two tested K. pneumoniae isolates. The indirect effect of plants extracts on the bacterial growth may be causing indirect effect on the metabolic activity and DNA (chromosome or plasmid) of cells. All tested plant extract contain many antimicrobial and antioxidant component by using GC-mass.

Abstract

Biofilm formation (BF) is one of the most important virulence factors of Candida spp. The aim of this study was to detect the prevalence of genes responsible in biofilm formation of C. albicans by conventional PCR technique. Among 49 vaginal specimens (VC), C. albicans was the most predominant species in percentage 22/49 (45%) and 27(55%) were non albicans. Out of 47 oral specimens (OS), 22/47(47%) were C. albicans, whereas 25(53%) were non albicans. At the present study; all C. albicans were biofilm producers with variable strength, out of 44 BF producers, 18 (40.9%) were low biofilm (LBF) with significant differences (P<0.05) between HVS and OS, 25 (56.8%) moderate or high biofilm (HBF) and just one isolate from oral was strong (very high) biofilm in percentage about 2.3% with no significant differences between HVS and OS. Molecular study of virulence genes correlated with biofilm C. albicans show that HWP1, ALS1, ALS3, SAP5, PLB1 and LIP8 genes were detected in 100% of C. albicans from vaginal and oral infections.

Abstract

Current study aimed to investigate the effect of piroxicam on some hematological and biochemcal parameters. For this reason forty males mature Sprage Dawlley rats were divided into four equal groups. control group administrated distilled water (G1), and three groups administrated (20mg/kg,30mg/kg,40mg/kg) body weight of piroxicam for 45 days. The results showed significant decrease (P<0.05) in hemoglobin (Hb) and packed ceq volume (PCV) in groups treated with (30,40)mg/kg of piroxicam, while the treated groups produced significant increease (P<0.05) in the total white blood cell count (WBC). On the serum biochemical porameters, Piroxicam caused increase in the level of liver enzyme amunotans ferase (ALT) and aspartate amintou (AST) Also recorded significant changes in the level of kidney function (creatinine, blood urea, uric acid). Histological studies appeared piroxicam caused more severe damage to the liver included depletion of glycoprotein, nearosis congestion, fatty change and inflammatory cell infiltration, kidney section appeared shrink of glomeruli, dilated renal tubules and necrosis were noticed in the renal tubules. Also the testes section appeared no effect in all the treatment groups except in the group which treated with piroxicam _40mg/kg) which showed thickening of somniferous tubules, shrink of leyding cells and necrosis of germ cells. This study shows that the toxic effect of piroxicam depends on time and conceutration of dose administration.

Abstract

Fifty of urine samples were collected from patients with urinary tract infection (UTI). The samples were collected from AL- Yarmuk hospital in Baghdad. All of the isolates were diagnosed using biochemical test and vitek. The result showed that 30 (60%) isolates identified as E.coli from 50 urine samples. The colicinogenic isolates were determined using cup assay methods. The results showed that 10 out of 30 isolates (33.3%) were detect as colicin producers from 30 isolate identified as E.coli depending on the clear zone that observed against the sensitive isolate. Colicin was extracted from the efficient isolate. Colicin activity (320 U/ml) was determined by well assay method. The protein concentration (520 µg /ml) estimated by using Bradford assay. The watery extract of Chilli papers (Capsicum baccatum) was extracted and used it as reducing and capping agent for gold nanoparticles synthesis. The characterization of the gold nanoparticles was done by UV-Visible Spectrophotometer, Transmission Electron Microscope (TEM), and resulting spherical nanoparticles with diameter ranging between (35-70 nm). The antibacterial activity of colicin alone and gold nanoparticles alone and combination of colicin with gold nanoparticles against ten isolates Pseudomonas aerugensa isolated from burn samples, using tube method. The results showed that all the three treatment had antibacterial activity but the combination of gold nanoparticles and colicin is better than used each one separately.

Abstract

A new procedure of depth estimation to the apex of dyke-like sources from magnetic data has been achieved through the application of a derived equation. The procedure consists of applying a simple filtering technique to the total magnetic intensity data profiles resulting from dyke-like bodies, having various depths, widths and inclination angles. A background trending line is drawn for the filtered profile and the output profile is considered for further calculations. Two straight lines are drawn along the maximum slopes of the filtered profile flanks. Then, the horizontal distances between the two lines at various amplitude levels are measured and plotted against the amplitudes and the resulted relation is a sloping line. The constant values of the equation of the least square fitting to the slope line and with the maximum value of the filtered profile multiplied by an empirical factor have been used to determine the depth to dyke-like source. Low errors percentages have been obtained from the application of the present procedure to a large number of dyke-like bodies and to the field example, indicating the successful of the method.

Abstract

Radiological assessment due to existing of natural occurring radioactive materials (NORM) in South Rumaila oil field was achieved in this study. Different samples including soil, sludge, scale, oil, and water were collected from different stages of oil and gas production in Markazia Degassing Station (SDS) in South Rumaila oil field. Radioactivity of Ra-226, Th-232 and K-40 were measured using gamma spectrometry system based on HPGe detector with efficiency of 30%. The results show that some locations within SDS are contaminated with NORM. The activity of Ra-226, Th-232 and K-40 range between 18.4 to 312.8, 9.4 to 140.8 and 66.4 to 800.8 (Bq/kg) respectively. The places to be more contaminated among the other places within the processing stages of oil and gas production within SDS are dehydrator and desaltor stages.

Abstract

3D geological model of a simple petroleum reservoir for Yamama Formation has been built in Abu Amood Oil Field using Petrel software, which is a product of Schlumberger. This model contains the structure, stratigraphy and reservoir properties (porosity and water saturation) in three directions(X, Y and Z).Geologic modeling is an applied science of creating computerized representations of portions of the earth's crust, especially oil and gas fields. Yamama Formation in Abu Amood Oil Field is divided into thirteen zones by using well logs and their petrophysical properties, six of which are reservoir zones. From the top of the formation these six zones are: (YB-1, YB-2, YB-3, YC-1, YC-2 and YC-3). These reservoir zones are separated from each other by barriers, which are of little or no porosity.

Abstract

A principal problem of any internet user is the increasing number of spam, which became a great problem today. Therefore, spam filtering has become a research fo-cus that attracts the attention of several security researchers and practitioners. Spam filtering can be viewed as a two-class classification problem. To this end, this paper proposes a spam filtering approach based on Possibilistic c-Means (PCM) algorithm and weighted distance coined as (WFCM) that can efficiently distinguish between spam and legitimate email messages. The objective of the formulated fuzzy problem is to construct two fuzzy clusters: spam and email clusters. The weight assignment is set by information gain algorithm. Experimental results on spam based benchmark dataset reveal that proper setting of feature-weight can improve the performance of the proposed spam filtering approach. Furthermore, the proposed spam filtering approach performance is better than PCM and Naïve Bayes filtering technique.

Abstract

In this paper, the rotation curve of the Milky Way galaxy has been determined using the observed HI emission line at a wavelength of 21 cm. Particularly, the Tangent Point Method was used in order to measure the rotational velocity and the distance to the center of the Milky Way. The measured rotation curve showed that the rotational velocity remains approximately constant at large distances from the center of the Galaxy. This is actually an evidence for the existence of dark matter in the halo of the Milky Way. If all the matter in the Milky Way is visible, then the behavior of the rotation curve of the galaxy should experience a Keplerian decline. The mass of the Milky Way within a radius of 15 kpc was also estimated to be ~ 1.65 × 1011 M⊙ which represents the mass of luminous matter in the Galaxy. However, if one assumes that the dark matter halo extends to 50 kpc, then the mass of the Galaxy should be ~ 5.615 × 1011 M⊙. The results indicate that the mass of dark matter in the Milky way within a radius of 50 kpc is ~ 3.96 × 1011 M⊙.
