The drug ranitidine (N-[2-[[[5-[(dimethylamino) methyl] furan-2-yl] methyl]thio] ethyl]-N-methyl-2-nitroethene–1,1–diamine hydrochlorid) forms (λmax=260nm) ion-pair association complex with [AuBr4]-1 at pH range 2-3 extractable with 1,2-dichloroethane under the appropriate experimental conditions. A calibration plot was set up from which some analytical parameters are derived. These parameters include: linear dynamic range LDR (1-80μg.ml-1), RSD (1.9 %), sandell sensitivity (0.0360), detection limit (0.11ppm), Corr. Coef (r) (0.9988), recovery (98.32 %), Erel (-1.68 %) aqueous - to- organic phase ratio (5:4) and the mole-ratio method approved the [AuBr4]-1 : RAN as being 1:1 .
Around fifty Escherichia coli isolates were isolated from sixty midstream urine specimens collected from patients visiting hospitals in Baghdad city. Approximately, 52% of all isolates were identified as extended spectrum beta lactamases (ESBL) producer. Results demonstrated that 92% of these isolates were sensitive to carbapenems. Only four β-lactamase coding genes were detected; blaTEM, blaPER, blaVIM and blaCTX-M-2. As a conclusion, this work revealed that local E. coli isolates harboured ESBL coding genes which may contribute in its pathogenicity.
Spectroscopic studies, in the ultraviolet region were carried out to characterize the
binding of isolated AFP with its labeled antibody in human malignant germ cell ovarian
tumor homogenates. Factors affecting the absorption properties of AFP, and the complex
of isolated AFP with the labeled antibody such as pH, solvent polarity (solvent
perturbation technique), spectrophotometric pH titration and thermal stability in the
presence of different concentration of sodium chloride have been studied. The
spectroscopic pH titration curves for human AFP and for the complex of isolated AFP
with the labeled antibody gave pka of 5.7 and 7.3 for histidine residue, respectively,
while 11.6 and 11.4 for tyrosine
The total suspended particles (TSP) concentrations in air at Kirkuk Oil Refinery and the areas around was determined by using low volume air sampler (Sniffer) at selected locations in two periods October 2010 and March 2011. The results of average concentration of suspended particles (TSP) are higher than the permissible limits of the Iraqi National determinants of (350 μg/m3) and the world limits of (60-90 μg/m3) at the two periods: October 2010 (818.94μg/m3) and March 2011(956.8μg/m3). The little difference between the two periods reflects the little effect of the seasonal changes. Comparison of the averages of the heavy metals (Pb, Ni, Cr, and Cd) with the national and world limits, noticed that they are higher than these limits.

The present study aimed to investigate CMV and Rubella virus as a causative agent of recurrent abortion, while the IL-2 levels were estimated as immune parameter during pregnancy period. A total of 63 blood samples were collected from recurrently aborted women, control non-pregnant women and control pregnant women. The results recorded 72.09 % CMV positive aborted women and 27.91 % Rubella virus positive aborted women. Levels of IL-2 were (437.03 ± 38.02) pg/ ml in first group, (390.51± 63.56) pg/ ml in second group, (32.98 ±15.12) pg/ ml in control group non pregnant women and (118.63 ± 24.81) pg/ ml in control pregnant women. High IL-2 levels in all studied women indicate presence of a factor affecting the immune system other than

Show MoreIn this paper, we present a concept of nC- symmetric operator as follows: Let A be a bounded linear operator on separable complex Hilbert space , the operator A is said to be nC-symmetric if there exists a positive number n (n such that CAn = A*ⁿ C (An = C A*ⁿ C). We provide an example and study the basic properties of this class of operators. Finally, we attempt to describe the relation between nC-symmetric operator and some other operators such as Fredholm and self-adjoint operators.

beetle. Females laid highest number of eggs when fed on raw wool (٤٥ eggs), then
on goats hair (٤٠.٤ eggs) lowest number of eggs (١٧.٢) when fed on natural silk, and
(١٨ eggs) on sheep hide.
Larval duration was shortest on raw wool (٧٨.٤ days), then goats hair (٨٤.٨ days)
and camels hair (٩١.٨ days). It was largest on human hair (١٧٦ days) and natural silk
(١٧٣ days). Larval mortality was lowest on goat’s hair (١%) then on raw wool (٤%)
and highest on natural silk (١٦%) and human hair (١٢%). Other material lies between them. These materials affected variably pupal duration, adult emergence.
The electric quadrupole moments for some nitrogen isotopes (12,14,15,16,18N) are
studied by shell model calculations with the proton-neutron formalism. Theoretical
calculations performed using the different set of effective charges due to the core
polarization effect. The effective charges in the p-shell nuclei are found to be
slightly different from those in the sd-shell nuclei. Most of the results we have
obtained are underestimated with the measured data for the isotopes considered in
this work.

A seismic study was conducted to re-interpret the Qasab and Jawan Oil fields in northwestern Iraq, south of the city of Mosul, by reprocessing many seismic sections of a number of field surveys by using the Petrel software. Two reflectors, represented by the Hartha formation, deposited during the Cretan age, and the Euphrates formation, formed during the Tertiary age, were delineated to stabilize the structural picture of these fields.
The stratigraphic study showed that the Qasab and Jawan fields represent areas of hydrocarbon accumulation. Seismic attribute analysis showed low values of instantaneous frequency in the areas of hydrocarbon accumulation. Instantaneous phase was used to determine the limits

In this study, short exposure of radish and cress plantlets to (0,10,20,30,50)ppm lead in nutrient solution (three months) in growth chamber conditions elicited an antioxidative response, measured in terms of lipid peroxidation, protein and proline accumulation and peroxidase and Catalase activity. Longer exposure to lead when radish and cress was grown outdoors for 90 days in pots filled with field soil with different lead content also resulted in higher lipid peroxidation and proline accumulation and altered protein content and enzyme activity. The results also showed significan
... Show MoreIn this article we derive two reliability mathematical expressions of two kinds of s-out of -k stress-strength model systems; and . Both stress and strength are assumed to have an Inverse Lomax distribution with unknown shape parameters and a common known scale parameter. The increase and decrease in the real values of the two reliabilities are studied according to the increase and decrease in the distribution parameters. Two estimation methods are used to estimate the distribution parameters and the reliabilities, which are Maximum Likelihood and Regression. A comparison is made between the estimators based on a simulation study by the mean squared error criteria, which revealed that the maximum likelihood estimator works the best.
In this work proton exchange membranes were prepared by a modified microwave casting solution technique, using the polymers blend (polyethersulfone (PES), polystyrene (PS), polyvinylidenefluride (PVDF)). Modified casting method was used to overcome the poor compatibility between hydrophilic, (PES, PS) and hydrophobic PVDF, by cooling the substrate during the film casting process to (4.5-5.5oC). Membranes were chemically modified by three reaction types to study the differences between their effects on the required properties for microbial fuel cell application. These methods use blend organic sulfonic acid precasting process and sulfonation by sulfuric acid post-casting process (APS), blending organic

The 2001 outburst of WZ Sagittae has shown the most compelling evidence yet for an enhancement of the mass transfer rate from the donor star during a dwarf nova outburst in the form of hot-spot brightening. It has been shown that even in this extreme case, the brightening can be attributed to tidal heating near the interaction point of an accretion stream with the expanding edge of an eccentric accretion disc, with no need at all for an increase in the mass transfer rate. Furthermore, it has been confirmed previous suggestions that an increase in mass transfer rate through the stream damps any eccentricity in an accretion disc and suppresses the appearance of super-humps, in contradiction to observations. Tidal heating is expected to be
