The new four complexes of Co(II), Ni(II) ,Cu(II) and Zn(II), with a multidentate Schiff-base
ligand [H2L] derived from Bis[(2,4,-diformyl)-6- ethylenediamine phenol]and
Phenylenediamin were prepared.The complexes were synthesized in direct reaction of the
corresponding metal chloride with the ligand. The ligand and complexes have been
characterized by spectroscopic methods (IR,UV-Vis, 1HNMR,A.A),chloride content,melting
point and conductivity measurement.The data of these measurements suggest octahedral
geometry around Co(II) Ni(II) and Cu(II) ions and tetrahedral geometry around Zn (II) ion.

The aim of this work was to prepare fumed silica from tetraethyl orthosilicate and study
the effect of reaction temperature on physical properties of fumed silica.
This study was focused on indigenously a system built for the preparation, it consists of
four stages which these chemical reaction stage, agglomeration stage, separation stage and
calcinations stage. Chemical and physical properties of product “fumed silica” such purity
( SiO2 content ), acidity, porosity, pore volume and apparent density had been in measured
and evaluated.
The preparation step was performed by chemical reaction in various temperature
( 200 , 250 , 300 , 350 , 400 , 450 ,500 ) oC at (1) atmospheric pressure.
The chemical reaction occurred can be represented by:
Si(OC2H5)4 + 2H2O SiO2 + 4C2H5OH
After reaction the produced fumed silica is tend to agglomerate, separate from ethanol
vapour by cyclone separators, calcinated at (350 oC) to remove the residual ethanol vapour.
It was deduced that the chemical reaction at 200 oC give fumed silica with higher acidity
compered to the reaction at 500 oC, with small particle size and high surface area.ur.

The rates of electropolishing copper cubiform surfaces in H3PO4 were studied under
natural convection conditions in a two-compartment cell. The following variables were
studied : anode shape and its dimensions ( cubiform ) , H3PO4 concentration, temperature and
viscosity of polishing solution.
The dimensions of cubiform of the anode were found to have no effect on the polishing
current density. Also it was found that the polishing current density to increase with
decreasing H3PO4 concentration and to increase with increasing temperature. The effect of the
temperature on the polishing current density was found to obey the Arrhenius equation with
an activation energy of 4.9 kcalmol-1. The polishing current density was found to decrease
with increasing viscosity of electropolishing solution .

Ablation rate and thermal conductivity for phenol- formaldehyde type novolac resin
reinforced with single walled carbon nanotubes (SWCNTs) have been studied via
experimental and simulation of Oxy – acetylene flame and Lee’s disc techniques respectively.
Simulation programs of heat transfer in three dimensions of ablative test for novolac and
novolac nanocomposites specimens were carried out using finite difference method (FDM).
Theoretical thermal conductivity was calculated according to microstructures model. Hotpress
technique was used to prepare the nanocomposites as well as novolac specimens using
flash molds at standard conditions. Thermal conductivity results show, that the values
increase progressively by succession of volume fraction of SWCNTs. Ablation rate behaves
inversely, where it drops at high volume fraction of SWCNTs. The thermal conductivity –
ablation rate relationship, displays two mechanisms, the first, associated with the starting of
ablation test, is recognized by ideal distribution of SWCNTs, which leads to good thermal
dispersion due to the formation of segregated network of thermal conducting paths. The
second mechanism is associated with in- run ablation test recognized by shearing cracks
appearance, which leads to earlier char production mechanism. Simulation thermal
conductivity results, , and when it compared with the experimental results, it observed, that
the experimental results, were located between the parallel and random direction simulation
values of SWCNTs, which is evidenced that the additives arrangement closed to parallel
direction more than random or perpendicular direction with respect to heat flux direction.
Keywords: Ablation, simulation, nanocomposites, and carbon nanotubes.

One from the most problems of multiwavelet transform is listing by the existing image
coding standards generally degrades at low bit-rates and lose some of data after applying
image reconstruction because of the underlying block based. Due to implementation
constraints multiwavelets do not posses all the properties such as orthogonally, short support,
linear phase symmetry, and a high order of approximation through vanishing moments
simultaneously, which are very much essential for signal processing. New class of wavelets
called ‘Multiwavelets’ which possess more than one scaling function overcomes this
problem. This paper presents a new image technique scheme based on reconstruct
approximation of Multiwavelets coefficients along with multistage vector quantization
named as Multi Stage Vector Quantization using the inverse computation of multiwavelet
transform, after apply the multi-stage vector quantization named as (MSVQ-IDMWT). The
performance of the proposed scheme is compared with the results obtained from regular
technique of reconstructing (IDMWT) from the SNR and PSNR values.

Several virulence and pathogenicity factors have been described from enterococci that enhances their ability to colonize patient's tissues, increase resistance to antibiotics, and aggravate the infection outcome. The present study aimed to investigate virulence and pathogenicity factors among enterococci species isolated from nosocomial and community acquired infection in Diyala. The study was conducted in Baquba General Hospital and Al- Batool Hospital for Maternity and children during the period from 1st. September/2005 to 30th. September /2006. A total of 343 specimens were collected from 213 inpatients and 130 outpatients. 200 (58.3%) were females and 143 (41.7%) were males. The mean age of patients was (32.8 ± 17.2) years. 44 isolates of enterococcal species were recovered from different clinical specimens and identified according to standard bacteriological and biochemical criteria. The presence of certain virulence and pathogenicity factors, namely; gelatinase and hemolysin production, biofilms formation, agglutination of erythrocytes, presence of capsule, and adherence to epithelial cells were detected. Data were statistically analyzed. The results showed that all isolates of E. gallinarium and E. avium were biofilm former compared to 76.7% and 70% of E. faecalis and E. faecium respectively. Furthermore, all isolates of E. gallinarium and 76.7% of E. faecalis were β-lactamase producer. Additionally, all isolates of E. avium and 76.7% of E. faecalis were agglutinated RBCs. The presence of capsule was highest among E. faecalis isolates (26.7%). The results also revealed that all E. galinarium and E. avium isolates were non-hemolytic. Furthermore, among 12 isolates which express β- hemolysis, 10 (33.3%) and 2 (20%) were E. faecalis and E. faecium respectively. α-hemolysis were found among 10 (26.7%) isolates of E. faecalis and 2 (20%) isolates of E. faecium. It can be concluded that Local isolates of enterococci species recovered from different clinical specimens are multi-virulence bacteria.

Diabetic retinopathy is one of most important complications of diabetes mellitus that can be treated by Nd:YAG laser. Laser is used in ophthalmic practice for photocoagulation and photodisruption The purpose of this study is to evaluate changes in immunological value after treatment of diabetic retinopathy by laser. Blood samples from 12 patients suffering from diabetic retinopathy were taken before and after laser treatment to coagulate retina to prevent leakage and hemorraghe to avoid deterioration of vision. The study showed clear changes in the values of immunology. main changes were in complemet(C3,C4) values which increased as noticed in after tretment because all lightinduced biological effects depend on the parameters of irradiation, the results suggest that the laser irradiation may play two principle roles in immunological changes. One , is stimulation of cellular proliferation , and stimulation of cellular differentiation that is responsible for different types of immunoglobulin.The other suggestion is that laser is acting as a triggering factor which induces systematic effects through the circulation when laser interacts with living cells so it has systemic effects through circulating blood.

Rubella is the mildest of common viral exanthems. However, infection during early
pregnancy may result in serious abnormalities of the fetus including congenital malformation
and mental retardation. The objectives of the present study are to determine the seropositivity
rate of anti-rubella IgG and IgM antibodies among premarriage girls in Diyala province.
A total of 358 subjects were included in the present study. The study was extended
from 7/April/2007 to 30/September/2008. 186 (51.9%) were females with mean age 16.7±
2.1 years, and 172(48.1%) were males with mean age 24.5 ±5.5 years. Those subjects were
randomly selected from those attending the Public Health Laboratory in Baquba for
premarriage investigations. Further information regarding age, residence, educational levels
was taken by personal interview. Detection of anti-rubella antibodies was done by enzymelinked
immunosorbant assays (ELISA) using (Biokit, Spain).Data were statistically analyzed
using SPSS version 13 computer assisted processing. P value <0.05 was considered
significant.
The results showed that all males and females were negative for anti-rubella IgM
antibody. However, 168 (97.7%) of males and 170(91.4%) of females were positive for antirubella
IgG antibody. Therefore, the rate of non-immune females was higher than that of
males (8.6% vs 2.3%). In conclusion premarital screening for anti-rubella IgG and vaccination
of non-immune girls could minimize the risk of rubella infection during pregnancy and childbearing
period.
