CdO thin films have been deposited at different concentration of SnO2 x= (0.0,
0.05, 0.1, 0.15) and (0.2) Wt. % onto glass substrates by pulsed laser deposition
technique (PLD) using Nd-YAG laser with λ=1064 nm, energy= 600mJ and
number of shots= 500. For it polycrystalline, the D.C. conductivity for the (CdO)1-
x(SnO2)x thin films decreases with increasing concentration SnO2 and decreases
with increasing of annealing temperature, found two activation energies increases
with increasing concentration SnO2 and decreases with increasing of annealing
temperature. Hall effect measurements show that the (CdO)1-x(SnO2)xthin films
were n-type, concentration of charge carriers nH decreases with increasing
of concentration of SnO2, also charge carriers nH increases with increasing of
annealing temperatures, while the mobility μH opposite behavior.

This paper is concerned with the problem of finding the mini max furthermore
semi-mini max estimators for the scale parameter of the inverted exponential
distribution(IED) in the direction of applying the theorem of Lehmann corresponding
to non-informative and informative prior distributions under symmetric «quadratic»
and asymmetric «precautionary» loss functions. The performance of the obtained
estimators have been compared empirically through simulation experiment with
respect to their mean square errors and mean absolute percentage errors

Two (ZnO) films were prepared by electrophoretic deposition (EPD) (ZnOEPD)
and chemical spray pyrolysis (ZnOSpray) on stainless steel (St. st.) and glass
substrates respectively. The sensing properties of these films to ethanol were
investigated as a function to temperature. The sensitivity to ethanol increases with
sample’s temperature. The method of film’s deposition is active factor on sensing
properties of the films. X ray diffraction (XRD) and atomic force microscopy (AFM)
techniques were utilized to study structural properties and surface topography of
sensors. The results of these techniques show the differences between these films
that effect on their sensing performances

In this paper, we introduce two new models of domination in graphs which are called
co-independent dominating set and inverse co-independent dominating set and they
are discussed in some graphs

Tumor protein (53) P53 is a member of family of proteins responsible for many
processes such as preventing cancer by controlling cell cycle, programmed cell death
(apoptosis), stress response, DNA repair and gene expression. It’s found that p53 have
many codons that may be subjected to mutation by many factors and these mutation
may lead to cancers in many systems of human body.One of most important sites of
mutation responsible for cancer development is codon (72) because it located on exon
(4).Codon (72) has three polymorphisms which are R/R, R/P and P/P according to arginine
substitution with proline in the proline’s rich area.The present study aimsto study
the distribution of codon (72)polymorphisms in Kerbala population and impact of many
risk factors such as smoking, diseases with genetic extension such as diabetes mellitus
and hypertension in addition to another factor such as age, residency, academic achievement
and gender on polymorphism of codon (72) of p53.Our study showed there is only
two types of codon (72) polymorphisms has been found in our cases, which are R/R
and R/P, P/P alleles not found in studied population. The results also revealed that no
strong association between one type on codon (72) polymorphisms and the studied risk
factors, such as smoking, diseases with genetic causation (such as diabetes mellitus
and hypertension) and other factor such as age, residency, academic achievement that
we are study. The correlation coefficients (r) were as the following; the smoking status/
polymorphism (r=0.07141);education /polymorphism (r=0.10955); age /polymorphism
correlation (r=-0.0636); and gender /polymorphism (r=0.1

factors are the addiction to smoking both types )cigarettes or water pipe(. The main objective of
the research is to study and determine the effect of the epidemic on students through the study
of the dynamic behavior of the proposed model. We assume that the student populations divided
into to three classes are the first class students potentials of smoking and second class smoking
students with a probability of quitting smoking permanently or temporarily last class of students quit
Smoking. The existence, uniqueness and boundedness of the solution of this model are investigated.
The local and global dynamical behaviors of the model are studied. Finally, in order to confirm our
obtained results and specify the effects of model’s parameters on the dynamical behavior, numerical
simulation of the PSQ model is performed

Due to the development in the electronics industry, it has become easy to use digital filters in
many digital applications. This paper includes adaptive digital filter simulations by using Leas Mean
Square (LMS) algorithm, which changed its coefficients repeatedly to become so controlled filter to
input signal to be passed without the unwanted signals. An application for this filter that have been
addressed in this research is to characterize )recognition of the( systems. The signals used in the
simulation are the amplitude modulated signals and sinusoidal signal. The results show that these
two application signals have good result when the proposed adaptive filter is used
