A new Spectrophotometric method for the determination of nitrite ion was studied. The method is based on the nitrosation reaction of nitrite ion with tryptophan in sulphuric acid medium. During it's reaction with nitrite, an intensively yellow-coloured substance is formed, having maximum absorption at 440nm. The calibration curve showed that Beerُُs law obeyed over the range of 0.05-3.0μg/ml of nitrite, with a detection limit of 0.00μg/ml. The molar absorptivity and Sandell index were 1.3887*104L/mol.cm and 0.00331μg/cm2 respectively. The optimum conditions affecting and interferences of the foreign ions were studied. The results obtained of the proposed method for determination of nitrite in meat samples were agreed with those obtained by the Naphthyl ethylene diamine NEDA standard method.

The lanthanide complexes of 4-(2-pyridylazo)-resorcinol are prepared in solid state. All compounds have beencharacterized by means of elemental analysis (C.H.N) molar conductance, magnetic susceptibility and analytical spectral studies IR and UV-Visible spectral techniques. While the complexes have additionally been characterized by differential thermal analysis data and are formulated as [Ln(C11H8N3O2)3].H2OLn = Pr3+, Nd3+and Sm3+; [ Ln(C11H8N3O2)3] Ln = Eu3+, Er3+and Yb3+. The results of these studies on the synthesis and structural characterization, suggest neutral lanthanide complexes in which the mono azo ligand being a uninegative (deprotonated form) and
2tridentate ligand. The absorption spectral profiles suggest a coordination number of nine around Ln(III) ions in the complexes. Key words: Characterization, Lanthanide(III)complexes, Azo reagent, Spectral studies.

Inner-shell ionization cross section (ICS) by electron impact are of interest not only to the basic collision physics for complex atoms, but also to various practical applications in material science and electron microscopy. Theoretical difficulties in the past were between the threshold and the peak, which occur usually four to five times the threshold energy. Theories based on classical mechanics are somewhat better than on Born cross section, but such theories usually requires adjustable parameters. We used the Gryzinski formalism to calculate atomic electron impact ionization cross sections for the elements (Fe,Co,Mn,Ti,Zn,& Nb). Good to satisfactory agreement was found for all atoms with the exception of (Nb), where the distance between our cross section and Deutsch-Mark formula become larger at the high values of the overvoltage (U). Moreover, when compared to other to available ionization cross sections for these atoms, calculated using other methods and semiempirical formula, the Gryzinski formalism achieved a level of agreement with experimental data that is as good better than the predictions from the other methods.

Ischemia –reperfusion injury is a complex phenomenon that results in cell damage through a biphasic process. Ischemia initiates the injury by a decrease or complete loss of energy supply needed to maintain homeostasis.
2Reperfusion increases cellular damage by a variety of proposed mechanisms such as inflammatory reaction and release of oxygen free radicals. I-R resulting in both pathological cell death (necrosis) and programmed cell death (apoptosis) in human and experiments This studyperformed to demonstrate the apoptosis and necrosis the renal tubules under the effect of I/R in by florescent acridine orange.Twenty fivemale rats were divided into six groups: control group, ischemia group (40 minute clamping of renal artery) and ischemia –reperfusion group (the removal of renal clamping after 1, 3, and 6 hours).The samples were prepared for histological technique and the sections stained with acridine orange and examined by florescent microscope.The results observed mild changes inthe ischemic group but the damage of the tissue and cells occurred in the reperfusion groups reaches the maximum effect after 1 and 3 hour, the necrosis and apoptosis were observed clearly.After 6 hoursreperfusion, emit orange fluorescence as evidence of nuclear fragmentation (apoptosis) in cells.We concluded that the apoptosis and necrosis occurred in the reperfusion after 40 minutes ischemia; also the acridine orange stain is effective stain to investigate the apoptosis and the cellular changes.

This study was carried out to show theprevalence of gestational diabetes mellitus(GDM) between urban and rural pregnant women in kut city of Iraq .A total of one thousand pregnant women (divided into 500 from urban areas and 500 rural areas),who had attended various antenatal clinics were screened for GDM by (one hour post 50 gm glucose load) oral glucose challenge test. Women who had an abnormal screening test proceeded to oral glucose tolerance testing by had a 3 hr. 100 gram oral glucose tolerance test (OGTT) and National diabetes data group criteria applied for diagnosis of GDM. This study showed the overall prevalence of GDM to be 3.2% (3.8% in urban women versus 2.6% in suburban women)

In order to have the best prediction of the non-linear viscoelastic behaviour of solid polymers,a new constitutive relationship has been obtained by inserting the stress invariants (1I) and (2I)into the formulation of multiple integral representation (MIR). The analytical part for the uniaxial tensile loading, it was found that creep could be separate into three components. First and second components, represent the contributions of the hydrostatic and deviatoric stresses respectively, while the third component represent the contribution of the synergistic effect of the hydrostatic and deviatoric stresses. Also, for the case of pure shear loading it was found that all components of creep are dependent on the deviatoric stress. Thus, new kernels have been obtained which called the hydrostatic, deviatoric and synergistic kernels, in terms of power law. Good agreement has been obtained from the comparison between the experimentalof other studiesand theoretical results of MIR under
2different types of loading for PP, PE and PMMA. This comparison proved that MIR gives the prediction with an average error of 0.05 %.

The present research deals with the effect for each number of layers to net the steel beams on the ferrocement layer considering the thickness of layer , strength of mix and distributed of steel. It foundthe strength of impact for combined beams greats than the base beams and number of layers effect clearly on the strength of impact, also the increase in thickness can increase resistance and there is an optimum of wire mish layer for ferrocement to increase the impact resistance.

The biggest exergy destruction occurs in the combustion chamberFor a specific values of 1OT, cdPR, and 3OTsteam injection will lead to improve the exergy destruction of the the combustion chamber, while has a reverse effect on the turbine, and has no effect on the compressor.

The main aim of this research is to investigate the effect of emulsified asphalt and cement (Salt resistance) mixture (i.e. the effect of emulsified asphalt–cement mixture) on the collapsibility of gypseous soil. The soil used in this study has been brought from Samara City (About 180 Km) north of Baghdad, with gypsum content of (69%).Series of collapse tests is performed on the soil in its natural state and after treatment by emulsified asphalt-cement mixture, Two percentages of
2emulsified asphalt are employed and four percentages of salt resistance cement –emulsified asphalt mixture are used in this study. the results of collapsibility tests show that the collapsibility of treated soil samples decreases upon increasing the percentage of emulsified asphalt. Better results were obtained when treated with emulsified asphalt –cement mixture. The results of collapse tests show almost the same behavior with increasing the percentage of emulsified asphalt and cement.
