the tissue cysts formed in the brain after 28 days is concerned. The number was 23.8 ±0.86 as
compared with the control group 38.6±1.029.The same compared is true of the lungs, tissue. The
number of the tissue cysts was 23.8±0.86 as compared with the control group 28.4±1.805.Concerning
the antibiotic Spiramycin ,the results showed the effectiveness of it in decreasing the tissue cysts
formed in the brain .The significant differences were (p<0.05),the rate of the cysts was 9.6±0.6 as
compared with the control group in which it was 22.8±1.067.The same effectiveness appeared on the
lungs, tissue as the rate of tissue cysts after 28 days of treatment was 4.6±0.509 as compared with the
control group in which was 17±1.14 and the significant differences were (p=0.000).The Ivermectin
drug showed a great effectiveness in minimizing the number of the tissue cysts formed in the brain and
the lungs. The numbers of the tissue cysts formed after 28 days were 3.2±0.374 and 1±0.316
respectively; significant differences are observed when these numbers are compared with the numbers
of the control group which were 22±1.843 and 19.4±1.435. Thus, the use of Ivermectin drug is
considered as a pioneer and fruitful study since this drug has not been used for the treatment of

DCT Image Compression by Run-Length and Shift Coding Techniques.

Bilal Kamal Ahmed

Journal of University of Anbar for Pure Science, 2011, Volume 5, Issue 3, Pages 39-44

The mathematical concept of a DCT transform is a powerful tool in many areas; it is also, served as an
approach in image processing discipline. In this work an image is processed as three color channel. The correlated
pixels values of an image can be transformed to a representation where its coefficients are de-correlated. The term "decorrelated"
means that the transformed values are independent of one another. As a result, they can be encoded
independently, which make it simpler to construct a statistical model. Correlated values are coded with run-length
coding techniques while shift coding used to decode the DC term and the other five lifting values. In this work, we
suggest to save the first five values from every block to keep it back without any significant errors.The obtained bit
rates was extended to be within range (11.4 , 2.6), compression ratio (2.76 , 13.34 )the values of the fiedility
parameters (PSNR) was within the range (31.61 , 46.21) for the lena test image in both sizes (128×128 and 256×256),
and PSNR was calculated as average for the three color channels, red, green , blue

ISMAIL K. AL-KHATEEB; KAISS R. IBRAHEEM; AYAD H. JASSIM

Journal of University of Anbar for Pure Science, 2011, Volume 5, Issue 3, Pages 40-48

The dithionate complexes of Bis(dithiobenzoato) iron(II) , Bis(3-chlorodithiobenzoate) iron(II) and
Bis(dithiosalicylate) iron (II) were synthesized. The thermal and photo transitions of complexes were identified by
using techniques of UV- Visible and IR spectrophotometers.
The results showed that the transition rate constant increased with elevation of temperature. Meanwhile, the iron
complexes were highly affected by light and the degradation elevated much more at sunlight compared to that of
daylight. The use of irradiation at 253.7 nm ( 7.83x10-19 J ) showed less significant effect for transition changes
compared to that of 356 nm (5.58x10-19 J ). These observations were confirmed by measuring absorption bands
with UV- Visible and IR spectrophotometers besides the possible chemical identifications

Effects of Parallel Processing Implementation on Balanced Load-Division Depending on Distributed Memory Systems

Subhi R. M. Zebari; Numan O. Yaseen

Journal of University of Anbar for Pure Science, 2011, Volume 5, Issue 3, Pages 50-56

Complex problems need long time to be solved, with low efficiency and performance. Therefore, to
overcome these drawbacks, the studies went toward the approaches of breaking the problem into independent
parts, and treating each part individually in the way that each processing element can execute its part of the
problem simultaneously with the others.Parallel processors are computer systems that consist of multiple
processing units connected via some interconnection network and the software needed to make the processing
units work together. Parallel processing is divided into three types; Shared, Distributed and Hybrid memory
systems.In this paper, distributed memory systems addressed depending on client/servers principles, the network
can contain any number of nodes; one of them is a client and the others are servers. The algorithms used here
are capable of calculating the (Started, Terminated, Consumed -CPU and Total Execution- times and CPU
usage) of servers and the Client's -CPU and total execution- times. This work addresses an improved approach
for problem subdivision in balanced form and design flexible algorithms to communicate efficiently between
client-side and servers-side in the way to overcome the problems of hardware networking components and
message passing problems. We addressed Matrix-Algebra case-study to display the effect of balance loaddivision
for this approach. The obtained results are checked and monitored by special programming-checkingsubroutines
through many testing-iterations and proved a high degree of accuracy. All of these algorithms
implemented using Java Language

steps-up from (132k) to (138k) at substitution rate (X= 0.05, Y= 0.1). But at increasing the substitution
rate for (Y) and the stability of (X) rate more than (X= 0.05, Y= 0.1), the temperature declines to
(125k). Finally, The crystal structure of the samples has been studies and tested by Scanning Electron
Microscope; knowing the components' rates in the compound; how the annealing temperature and the
imposed pressure affect the compound; how the compound partial substitution affect in the
components; and specifying the quantitative and qualitative rates of the components in the compound
