This study includes a detailed description of dust storms occurred in 3 May, 2005. The research
analyses the synoptic conditions for the pressure system movements, temperatures changes and
the wind time distribution. The condition leads to enhancement or reduces the dust storm that
heading to Iraq. The analysis of the synoptic situation accompanied with the selected day is
illustrated using the reanalysis data of ERA-Interim. Also, Back-Trajectories from Noaa Hysplit
model backward trajectories is also used for three cities in Iraq (Mosul, Baghdad and Basra).
In this study, a simple classification for the selected case is created based on the total amount
of the dust in the atmospheric column (dust_load) simulated by the regional climate model of
RegCM4.

Simply, sensitive and accurate spectrophotometric methods have been improved for the
determination of sulfanilamide (SNA) drug in pure and synthetic sample. This method is based
on the reaction of sulfanilamide (SNA) with new organic reagent (BYN) it was prepared by
reaction between ethyl acetoacetate with 2, 4-Dinitrophenylhydrazine. The azo dye product
shows absorption maximum at 435 nm. The linearity ranges of sulfanilamide are (2 – 20 μg.
mL-1) with molar absorptivity (7671.2 L.mol-1.cm-1), Sandell's sensitivity index (0.0224
μg.cm-2), detection limit and Quantification limit (0.1598, 0.4843 μg / ml) respectively. The
results showed there are no interferences of excipients on the determination of the drug. The
proposed method has been successfully applied for the determination of sulfanilamide in pure
and in synthetic sample.

Script picture analyses use algorithms to turn images of text into readable computer data. The
goal of script picture analyses is pattern recognition of script and graphics combinations from
images for extraction of the data. This paper solves a long-existing problem in pattern
recognition in script images regarding recognition of characters and words using a computer
processor. The proposed system rely on main steps of execute, first step: is load English script
of image file, second step: is partition image file to several image pages, third step: is divide
the image into number of blocks, and final step: multi-block method can be used in each row
of the script image with parallel processing using a multi-core computer (one processor P1, two
processors P2, three processors P3, and four processors P4) with rapid processing for script
images for pattern recognition . The outcome obtained with a multi-core computer is very fast
for processing script images and is efficient and accurate. It can use the modified algorithm in
multi-processor system that available now and not used all the capacity in processing in one
processor as in old computers.

dissolved in 2 ml saline (I. P.) for 9 days (control group). All animals, were euthanized on day
18 and, blood was collected and serum was obtained to estimate levels of serum enzymes (RMS,
ALT, AST, TSB, TSP, BUN, and Creatinine). The dependent parameters were heart rates,
respiratory rates, body weight and body temperature, in addition to some hematological
parameters, clotting and bleeding times, total and differential leucocytes count. The results
revealed that the levels of biochemical parameters increased in paracetamol- treated rabbits in
comparison with the non- treated groups, while the total protein content decreased. The extract
exhibited a significant reduction in biochemical parameters (P<0.05). In conclusion, it is
obvious that Sibahbah aqueous alcohol extract possesses a significant hepatoprotective effect
against paracetamol – induced hepatitis.

Genetic methods based on Polymerase Chain Reaction-Restriction Fragment Length
Polymorphism (PCR-RFLP) are widely used for microbial species determination, in this study,
PCR-RFLP technique was used to target the intragenic between 16S and 23S rDNA (dnaJ gene)
for rapid detection and identification of twenty Staphylococcus species isolates. The RFLP
analysis of the dnaJ gene and the digestive enzyme ApoI was designed for a rapid and accurate
identification of the selected genome. In this assay, the conserved intragenic region between
16S and 23S fragments subsequently digestion of the amplicon with restriction enzymes.
Therefore, dnaJ gene with digestive enzyme ApoI were studied to differentiate Staphylococcus
genus. The results confirmed that S. epidermidis, S. hominis, and S. lugdunensis had 3 bands
and S. aureus 4 bands. However, the restriction enzyme not fail but there are no restrict site in
there amplified genome segment for S. haemolyticus, S. xylosus and S. auricularis. Our study
found that a restriction enzyme ApoI does not benefit in classifying the species of the genus
Staphylococcus spp.

In recent years, transmitting data on the Internet became a daily usage of people, such as
sending emails, online shopping and so on. Generally, this data should be confidential and
hence it should be secured by using cryptosystem algorithms. A new algorithm of securing the
transmitted data by combining Playfair Cipher with Legendre symbol is presented in this paper.
In this algorithm a large prime number ???? can be chosen by both of sender and the receiver in
order to calculate Legendre Symbol (????
????
), ∀ 1 ≤ ???? ≤ ????−1 and then sorting them in a
random order set. Moreover, as Legendre symbol is either 1 or -1, then this helps them in the
proposed algorithm to use two tables with two keywords for the encryption and decryption
processes instead of using only one table and one keyword as in the standard Playfair cipher
algorithm. Thus, our proposed algorithm increases the security level of the transmitted data on
the insecure channels comparing with the standard algorithm.

Glass-ionomer cement (GIC) is one of the common restorative materials, but they exhibit
relatively low mechanical properties. The aim of this study is the improvement of the properties
of glass ionomer cement by incorporation of (1, 3 and 5wt.%) of different types of ZnO and
TiO2 nanoparticles. Two conventional types of GIC Luting Cement were used (Ketac Cem
radiopaque and Polyalkenoate Cement). Flexural strength and diametral tensile strength were
calculated after 24 hr. and 3 weeks according to ISO4049. The results show a slight increase in
flexural strength of glass ionomer cement, after adding 1 wt.% of both ZnO/NPs and TiO2/NPs,
while the increase in flexural strength was significant at 3wt.% which reached 14% and 15.71%
for ZnO/NPs and TiO2/NPs respectively for Ketac Cem radiopaque and reached 4.79% and
8.59% for Polyalkenoate Cement at the same ratio. Also, the flexural strength value increased
after 3 weeks for all incorporation weight percentages. The modified tested cement also
exhibited higher diametral tensile strength after 3 weeks, than that recorded in 24 hr for all
concentrations (1, 3 and 5wt.%) of ZnO and TiO2 nanoparticles, in addition to the increase in
diametral tensile strength after the incorporation of nanoparticles with glass ionomer cement.
Within the limits of this study, a considerable increase in flexural strength and diametral tensile

The idea of bounded subset of a topological vector space was introduced by von Neumann. As
a result of playing an important role in functional analysis that motivated the concept of more
general and abstract classes of bounded sets, it is called bornology. That means, it is applied to
solve the questions of boundedness for any space or set ???? in general way not only by usual
definition of bounded set. However, we take a collection β of subset of ????, such that, satisfying
three conditions, ???? cover Χ, and ???? stable under hereditary, i.e., if ???? ∈ ????,???? ⊆ ????, then ???? ∈ ????
also finite union. Basically, a bornological space is a type of spaces which possesses the
minimum amount of the structure needed to address the question of boundedness of sets and
functions. In addition, since bornology has shown to be a very useful tool in various aspects of
functional analysis, it has been considered by several researchers in different areas. In this
paper, we consider the concept of semi-compactness in bornological space and study some of
its properties.

The Binary Cluster Model (BCM) has been employed with the single particle harmonic
oscillator and Gaussian wave functions to study the ground state density distributions and the
elastic form factors of proton rich 8B and 17Ne halo nuclei. The Glauber model with an optical
limit approximation has been used to study the reaction cross sections for these nuclei in the
low and high energy regions. The calculated results of reaction cross sections of these nuclei at
both low and high energy give good agreement with experimental data.

The two-body model of [???????????????? + ????(????)] within the single-particle wave functions of the Woods
Saxon (WS) and Harmonic Oscillator (HO) potentials has been used to study the ground state
features such as the neutron, proton and matter densities, the associated root mean square (rms)
radii and elastic form factors of exotic 17F and 19C nuclei. The long tail manner is clearly shown
in the calculated matter densities of these nuclei. According to the calculated results it is found
that this model provides a good description on the nuclear structure of above exotic nuclei. The
reaction cross sections for these nuclei have been studied using the Glauber model with an
optical limit approximation at high energy region.
