In this study, Enterococcus bacteria was isolated from the Iraqi local dairy products then it have
been compared with global products from )Saudi Arabia, Jordan, Syria, Iran(,An study of absorption
spectrum have been achieved to the planted bacteria in the middle nutritious before and after the
irradiation by laser, as used several lasers with wavelengths )405, 532, 650(nm and the laser power
of irradiation variable )1-20( m Watt and different irradiation times )1-24(min at different doses of
radiation. The results showed that the bacteria isolated focused largest amount of Iraqi and Syrian
Milk, it turns out that the bacteria isolated positive Gram appeared on the spherical shape under a
microscope by )68.8%( of the total isolates, found them almost )79.8%( of the genus )Enterococcus(,
and have found that higher absorption of isolated bacteria in the extent of wavelengths UV near
visible light within the wavelength )235(nm and the absorbance of the bacteria less when irradiation
laser، note from the results that the effect of the laser (405)nm his percentage kill of bacteria higher
than the laser )532(nm This has the largest of the laser effect )650(nm under the same conditions, the
study showed required to get the proportion of killing )100%( of time is )21( min and at least increase the
laser power or radiation dose, and increase energy density by increasing the exposure time enough
to damage the inside living cell and kill bacteria. The study has shown that lasers can be used as a
tool, rather than the traditional pasteurization sterilization that lose Taste the milk and some of its
properties.

Consider G(E,V) be a finite, undirected and simple connected graph. This
paper includes study of some properties that illustrate the relations between three
numbers in a graph which are chromatic, domination, and independence with
special restrictions. Finally, we compute these parameters in a new graph namely
K4 -isosceles triangular graph

The capacity is an important requirement in the development of cellular
systems. There are many methods to increase cellular system capacity such as
using small cells (micro cell) in hotspot areas. This method increases the number
of handovers for high speed users, which causes an increasing of the number of
blocked handovers. It is possible to decrease the number of handovers by using
umbrella cell technique. This technique uses large cell (macro cell) to serve high
speed users and small cells to serve low speed users. In this paper, two models are
simulated by using MATLAB program, with and without umbrella cell in Wide
band Code Division Multiple Access (WCDMA) system. The results of this work
show an improvement of the handover process by large reduction of the number
of handovers, and decreasing the probability of blocked handovers in the case of
umbrella cell technique compared to the other technique

There are a lot of challenges facing the process of tracking moving targets, particularly when
using fixed or moving cameras, so there is a need to find appropriate solutions to solve the kind
of problems. The process of tracking moving objects becomes easier when the background is
fixed (i.e., static) in order to distinguish the moving objects from the static parts by different
operations.
In this research, we attempt to utilize a technique for building a background template for this
scene, and this model replaces when time changes are caused by weather adversity or dynamic
illumination.
We use the accumulative histogram for each block of the video frames to compute the background
value of that block. Hence, the most probable mean of the block will be adopted as the background
mean value, and this value can be subtracted for the values of pixels which belong to that block.
The mean values of all corresponding blocks which lay in the taken successive block are used
to get the most redundant mean which is adopted as the background value of that block.
For the purpose of identifying the moving objects and separating it from other objects as well
as the background we apply the method of region grown. Some features like ( the center of any
object) are extracted, and they are used to fix the trajectory of the identified object by tracking
the changes in position coordinated from frame set to other set by using Euclidean distance
metric.

MgO nano photocatalyst is successfully synthesized from its raw materials. The X-ray
diffraction analysis indicates that the prepared films are polycrystalline structure, which is
compatible with standard tables. The morphology of (MgO) nanoparticles, is examined by using
the atomic force microscope (AFM). It shows that it is constructed from nanostructure materials.
HHO electrolysis cell of glass Pyrex has been designed for this study. SnO2/Al2O3 electrodes
is prepared as well. The effect of adding nano photocatalyst on the volume of gas production
was studied. In addition, the effects of current and time on the volume are investigated

In this paper, we introduce new types of Nα-continuous mappings by using Nα-open sets in topological spaces, such as

The purpose of this paper is to discuss the main factors that affect the construction cost of school
buildings in Kerbala. A survey of )16( supervising engineers, )11( implementing engineers and )9(
contractors was performed The survey included )33( different factors affecting the construction cost
of school buildings in Kerbala and their degree of importance. The severity of those factors was
measured by the level of importance and ranked according to the severity index for supervising
engineers، implementing engineers and contractors and a combination of all respondents.
There is an agreement )correlation( by each group and the overall ranking by all participants. It
was concluded that Incorrect planning previous experience and design quality are the most severe
factors with relatively high overall scoring.
The paper provides a holistic approach that considers all factors affecting school buildings in
Kerbala and the interplay between them. It will serve as a guide to the focus areas to be considered
in policy development aiming at improving conditions in the construction industry school buildings
programs

The cellular concrete blocks )Thermostone( are consider as a one of important construction
materials which is used widely as an interior masonry walls and partitions in frame structures, as it
has many economic and practice benefits.
The aim of the research is finding correlation between ultrasonic pulse velocity and compressive
strength of different types of locally available thermostone. To assess compressive strength of
thermostone depending on its ultrasonic pulse velocity, by using direct and indirect methods with
distances of )10, 20 and 30(cm. Four correlations were obtained by using linear regression method.
According to the test results, ultrasonic pulse velocity cannot be used as a non destructive test to
estimate compressive strength of thermostone, as thermostone is a porous material which dispersal
the waves

Tin dioxide )SnO2) nano particles were successfully prepared by modified liquid phase
deposition )LPD( and controlled by modulating the )pH( value. The structural and morphological
properties of the particles were characterized by X-ray diffraction (XRD) and field emission scanning
electron microscope )FE-SEM(. )XRD( patterns show that all the prepared samples have high purity.
)FE-SEM( micrographs show that the obtained materials are nano-size materials. It was found that
the size and distribution of the particles depends on the )pH( value of the reaction media where the
particle distribution improves with )pH( value increasing. The growth mechanism of )SnO2(nano
