This research aim to evaluate the concise rocedure for analysis and design of
Reinforced concrete structure to resist internal blast pressure. This evaluation will be
locate the required thickness of the roof structure in addition the quantity , ship and
connection mechanism of steel reinforcement. In order to verify the asuracy of the
theoretical analysis and design procedure of Reinforced concrete roof structure to resist
internal blast pressure. It was intended to carry out a field test for the structure designed
after specified the internal dimensions of the structure (3.30*3.30*2.60)m , charge
weight (1.5) kg and the ecommended degree of protection usually in terms of ductility
ratio= 2.0.The natural period and the dynamic load factor were also calculated for the
above structure .The objective of the test was justified since no scabbing from the roof
was observed this means the thickness (25) cm of roof can keep all the out side
individuals, equipment and buildings safe and away from the danger of fire and
fragmentation during the period of blast pressure . The individuals and equipment
should be kept clear away from the venting zone. A good agreement was found
between the. theoretical and experimental results.

Footprint in standing position were taken for 100 young females, 50 were from urban
area and other 50 from rural area. The heel index and lateral deviation of big toe were
measured. Footprint is simple test that can be done easily by medical or nursing staff. There
is significant statistical difference between the two groups. This might be explained different
life style and shoe wearing in the two communities. Flat foot and hallux valgus is less in
young female in rural Iraqi community. The rural style of life in our community reduce the
possibility of acquiring flat foot and hallux valgus.

In this paper iterated method (Adomain’s method) used to evaluate an approximate

technique is proposed in applying Aitken’s Extrapolation method,the new proposed
technique, the convergence of adomain’s method is increased. Program associated with above
methods is written in MATLAB language , by using method will be shown.

Effect of aqueous extracts of Cyperus rotundus , Teucrium polium and Prosopis farcta
on the levels of blood glucose , cholesterol and triglycerides were investigated in normal and
alloxan induced diabetic rats . The results indicated a significant decrease in glucose level in
normal and diabetic rats . The aqueous extract of Cyperus rotundus produced significant
decrease in cholesterol and triglycerides level but the aqueous extract of Prosopis farcta
produced significant decrease only in triglyceride levels wherease aqueous extract of eucrium
polium produced no significant decrease in cholesterol and triglyceride levels in diabetic rats.

In this paper a new method for solving the integral equation in space-time which arises
in mathematical physics, mechanics and the heat conduction theory is presented. The central
idea is: First, differentiating both sides of two-dimensions Fredholm integral Equations ntimes with respect to both variables x and t, second, substituting the Taylor series of two
variables for the unknown function, and third, obtain a system of linear equations which can
be solved by a suitable truncation scheme .Lastly,the double-quadrature rules are used to
calculate the required integrals in this procedure. The presented algorithm is illustrated by
some numerical examples with comparison tables.

fer regions and their average sum to (0.17 µg/ml and 0.27µ g/ml )and (0.15µg/ml and
0.19 µg/ml ) respectively .Iodine and Iodide distributions are affected by some
hydrochemical properties especially pH and electrical conductivity which reflect washing
reaction between well water enriched with dissolved salt ( cations , bicarbonate, carbonate )
and the constituents of geological formations exposed at both regions.
Ground water at both regions are used for different purposes including domestic and
agriculture in addition to drinking water. Such uses may affect differently on human health
and consequently on the endemic iodine deficiency diseases known to occur among the
population of the northern IRAQ. Apparently, iodine, iodide contents are related to the
number of IDD patients and such relation is affected by various factors including pH,
dissolved salts and sulfur species, which determine the bioavalability of iodine for the
biological processes.

The main result of this paper is to show that Oren updating formula for unconstraind
optimization is also satisfy a minimum property with respect to the measure function
of Byrd and Nocedal. The Oren formula gives the unique solution of the variational
problem.This idea may be extended for the inverse of any positive difinite matrix.

Pediculus humanus capitis (head louse) infestation is a common problem in school aged
children. A cross-sectional study done in AL-Alam village in Salahadin Province in 2002
aimed to estimate the incidence of Pediculus capitis among primary school children of age
ranging between 7-14 years.
The study showed that out of 170 children 36 (21.2 %) were infested with Pediculus
capitis. Higher proportion of infestation was found among female. Infestation among younger
children (7-8 years) was very high (40.3 %) in comparison to other age groups. Also, higher
proportion of infestation was found among children lived in large families and whom parent’s
educational levels were low (illiterate). It has been concluded that Pediculus capitis
infestation is more common among younger children with poor personal hygiene and among
longhaired children in this rural area.

This research includes a detailed study of the variation of heavy minerals in the recent
sediment of the Lesser Zab River. The studied sediments contain four main mineral
groups(iron oxides , chromite ,epidotes ,amphiboles and pyroxenes)that make the main heavy
mineral assemblages of the Lesser Zab sediments. Furthermore , few amounts of garnet and
flaky minerals are recorded. Heavy minerals have been identified and estimated using both
polarizing and binocular microscopes. The results suggest that there is significant difference
in the mineralogical and lithological contents before and after the Dokan Dam .The sediments
generally are classified as lithic arenites that composed principally of rock fragments
followed in amounts by quartz ,feldspars and heavy minerals.

Effects of diets containing fats on blood parameters and some carcass characteristics
were investigated. Broilers were fed one of four different isonitrogenous diets containing 5%
added fat (Soybean oil, Corn oil, Sunflower oil and Vegetable oil). The effect of different fat
sources on the protein rations of thigh and breast muscles of broilers was statistically not
significant. The effect of different fats on serum cholesterol and mean lipoprotein in broilers
was significant (p<0.01), but the effect of those on triglyceride values was not significant.
The effect of sex on blood parameters for cholesterol and triglyceride values was not
statistically significant, significant (p<0.05) for lipoprotein.

The phosphate ions adsorption of some calcarious soils of Nainawa and Kirkuk regions
from 0.01 M KCL solution containing (1-12) micromoles P has been studied .The different
type of soils (32.4-39.84) % CaCO3 were fertilized with (22.5, 45, 90) kg P/ha and planted
with maize ( Zea mays L. ) in 1 kg pots for five years. Adsorbed phosphorous at equilibrium
solution concentration of 0.2 ppm P ( Ce = 0.2ppm P ) was determind .It was established an
inverse relation between adsorbed P at Ce = 0.2 ppm P and the extractable phosphorous was
established. The amount of adsorbed phosphorous at Ce = 0.2 ppm P diminished as the rate
of applied fertilizers increase. From the data obtained in this study one may conclude that for
the studied soils an average of 69.3 ppm extractable P correspond to an equilibrium soil
solution of 0.2 ppm P ( Ce = 0.2 ppm P ) considered as adequate nutration level for most field
crops, and justifies the use of P adsorption isotherms for evaluating the phosphorous fertilizer
requirement.

The experiment was conducted at Al-Haweja / Governorate of Karkuk during the season
2004 using ten varieties of cotton (Coker310, Lachata, Halab90, Halab33, Deer22, Nazley87,
Montana, SP8886, Stonvill474 and Stonvill887. The varieties planted at mid April using
Randomized Complete Block Design with three replications in two farms, the first under
surface irrigation and the second under sprinkler irrigation using fixed system. The results
showed:
Highly significant differences among varieties under the two irrigation methods,
combining analysis showed highly significant differences between the two irrigation methods
for all characters except boll weight, while the differences among varieties were significant
for all studied characters. The interaction between the two factors was significant for number
of vegetative branches and number of nodes to first flower branch , the surface irrigation
method exceeded the sprinkler one for the most characters, the variety Montana exceeded the
others for the most characters, the seed cotton yield showed significant positive correlations
with plant height, number of flowering branches, number of bolls, boll weight and significant
negative with number of vegetative branches and number of nodes to first flower branch
under the two irrigation methods and their average, path coefficient analysis showed that
number of bolls per plant had highest direct and indirect effects on seedcotton yield and can
be used in breeding programs to improve seedcotton yield
