Computational electromagnetics (CEM) may be broadly defined
as the branch of electromagnetics that intrinsically and routinely
involves using a digital computer to obtain numerical results. This
paper presents a technique for the measurement of the radiation
fields of discone antenna by using moment method (MM). The
measurements are carried out for the perfect conductors by using
the dipole feed. The numerically calculated results are
experimentally validated for a discone antenna from 300MHz -
2.4GHz. The radiation patterns of discone antenna for multiple
frequency and the effects of feed location on antenna\'s operations
are discussed.

A study was conducted during the period January to June 2008, a
total of 856 urine samples were collected from male and female in
variable ages group with symptoms suggesting urinary tract
infections (UTIs) at AL-Sheffa General Hospital in Basrah district.
(36.1%) of samples collected from males gave positive results for
infected with UTI, while positive samples from females were
(63.9%). Women age 10-49 years recorded high rate of infected
with UTI in comparison to those age above 50 years. In male
patients, the highest rate of UTIs was recorded in age group above
50 years. Overall, Escherichia coli was the most common
uropathogens and was found in (52.12%) of all samples. Other
bacterial uropathogens were identified and their percentages were
as follow: Klebsiella pneumoniae (16.98%), Enterococcus faecalis
(13.21%), Pseudomonas aeruginosa (7.1%), Citrobacter species
(5.9%) and Staphylococcus aureus (4.72%). Antimicrobial activity
of 12 antibiotics were tested against all pathogens identified. The
highest resistance was shown to ampicillin (81.32%) and amikacin
(62.97%) of all uropathogens isolated, while ciprofloxacin and
gentamicin shown a high antimicrobial activity, (13.62%) and
(14.62%) respectively.

Asurvey study was carried out in this research to
enumerate the the number of patients at Nasseria chest
disease centre tuberculosis from year 2004 to year 2008
and the total number was 4313 person ,thenmber 1036
person have Active TB infection (713 male and 323female)
that percentage 24%and 385 person cause releapase at
(265 male and 120female) that percentage 9%, the
infections outer the lung 1195cases ( 631 male and 564
female ),that percentage 27.7%the person that have no
active tuberculosis 1704 (966 male and 738 femal)that
percentage 39.5%.The aim of research to survey for patient
numbers to Nasseria chest disease center and the
percentage of that cases from the tatal numbers and
discovery the kind infections at two genus ,male and female
.

In this research, A theoretical computational investigation for studying the analysis method for possibility to produce magnetic lens of free from a rotation and distortion. The doublet project magnetic lens with different pole pieces has been designed. The radial and spiral distortions have been corrected by using this lens at low and high magnification regions , after the magnetic field has been computed. Where, a rotation and distortion free images have been obtain by suitable choice of the ratios values of gaps and bores of first lens and second lens.

Abstract A study was conducted on some physical and chemical properties of Al-Gharaf river water in Thi - Qar governorate to know the changes that were happened on the some physical and chemical properties of the river. Water samples were collected from one region in the southern of Gharaf city along one year from January to December 2009 . Some physical properties as (pH) and (EC) were measured , chemical properties represented by total dissolved solid (TDS) , total hardness (T.H) and the concentrations of positive ions such as ( Ca++ and Mg ++) and negative ions such as (Cl- , SO4= , NO3= and PO4≡ ) in addition to oil were measured too . The concentrations of chemical properties were estimated by mg / l .

Batch verification is the ability to verify multiple digital
signatures together. This method can reduce computational cost
required to verify these signatures individually. In this paper, we
present a fast algorithm based on DSA-type algorithm. Our
algorithm gives the same level of security as compared with
Bellare et al. algorithm and at the same time it is more efficient
since it does not require computing of modular inverse neither at
the signing side nor at the verifying side. The proposed algorithm
need to compute modular inverse at generating public key and this
is done once.

This study was designed to evaluate some hematological parameters (Red blood cell count (RBCs), hemoglobin estimation (Hb), Packed cell volume (PCV), blood indices (Mean corpuscular volume, Mean corpuscular hemoglobin, Mean corpuscular hemoglobin concentration) (MCV, MCH, MCHC) and the level of iron in rats exposed to oxidative stress by 0.5% hydrogen peroxide (H2O2) and then treated by aqueous of black currant (Vitis vinferia.L) extract and comparing to the vitamin E.
Twenty-four adult male rats were divided randomly into four equal groups (six rat/ group) and treated as follows for 42 days. The Rats in first group (GІ) were received normal water with oral intubation of sun flower oil (1ml /rat) and consider as control group. Animals of the second group (GΠ) were received 0.5% H2O2 in drinking water, while rats of the third group (GШ) were received 0.5% H2O2 in drinking water with oral intubation of vit. E (400 I.U/Kg/B.W/day) diluting in sun flower oil.The animals in fourth group (GІV) were intubated daily (60 mg/kg/B.W/day) of aqueous extract of black currant plus 0.5% H2O2 in drinking water. Fasting blood samples were collected at 0, 21; 42 days of experiments. Blood hematological parameter and serum Iron were estimated. The results of the present study demonstrated that administration of 0.5% of H2O2 in drinking water caused a significant decreased in RBCs count, Hb content, PCV, MCV and Iron concentration in serum while there was no change in MCH and MCHC in group (GІV) compared to control and other group. In addition, there are a significant elevation in (RBCs, Hb, PCV, MCV, and MCH) in group treated with aqueous extract of black currant plus 0.5% H2O2in drinking water compared to control and H2O2 group, with no change in concentration of iron in (G Ш and G ІV) at end of experiment. It was concluded at the end of experiment that the aqueous extract of black currant exerts protective effect against oxidative stress and it's more active than Vit.E. It was recommended to evaluation the hematological parameter in some chronic diseases have relationship to biomarker of oxidative stress.

In this paper, numerical solutions of the generalized Burgers-fisher equation are obtained by using Variational Iteration Method (VIM) and compare our result with exact solution numerical results show that variational iteration method is more efficient and powerful method.

In 1969 S.K.Skaff introduced the generalized conjugate function.
In this work the concept of a generalized conjugate function for n variable is defined and some of its important properties are examined. Many of the standard results which hold for N-functions and conjugate functions of a real variable will be generalized here.
