226Ra-Be
Using
the
MCNP5
Code
The
irradiator
226Ra-Be
unit
available
at the
Physics
Department
of the
Sciences
Faculty,
Damascus
University,
was
simulated
by using
the MCNP
code.
Calculations
of
neutron

Analytic
Approximate
Solution
of
Blasius
Equation
Using
Homotopy
Perturbation
Method (HPM)
In this
paper,
an
incompressible
viscous
fluid
flow
over a
flat
plate is
presented.
The
homotopy
perturbation
method (HPM)
is
employed
to solve
the
well-known
nonlinear
Blasius
differential
equation.
We used
this new
analytic
approximated
technique,
which
gave us
a very
close
result
to the
exact
solution.
The
obtained
results
have
been
compared
with
numerical
and
exact
solutions
of
Blasius
equation,
showing
the high
accuracy
of the
results
obtained
in our
study.

Free
Breathing
Abdominal
Imaging
with
Fat-Water
Separation
Using 3D
Radial
Stack-of-Stars
Trajectory
In
earlier
studies
of
fat-water
separation
using
dynamic
imaging
applications,
the
three-dimensional
(3D) MRI
failed
to
provide
high
spatial
and
temporal
resolution.
This
work
proposes
a
fat-water
separation
strategy
in the
abdomen
during
free
breathing
using
the 3D
stack-of-stars
(SOS)
radial
sampling
technique.
Radial
trajectories
are less
sensitive
to
motion
and have
a higher
sampling
density
for the
central
k-space,
allowing
for
better
performance
in
capturing
dynamic
information.

Assessment
of
Natural
Radioactive
Concentration
Levels
in the
Oil
Drilling
Wells in
Erbil
Governorate
Blocks
The
activity
concentrations
of
226Ra,
232Th
and
40K
in the
core
samples
obtained
from
Erbil
oil
blocks
have
been
measured
by using
NaI(TI)
gamma
ray
spectrometry.
Radiological
hazard
indices
were
evaluated
from the
activity
concentrations
of these
radionuclides
in order
to
estimate
health
effects
of the
exposure
of the
public
to
radiation
at the
studied
area.
The
calculated
Radium
equivalent
activity
(Raeq)
varied
from
(33.48)
to
(321.13)
Bq.kg-1
with a
mean
value of
(127.50)
Bq.kg-1.

Optical
and
Structural
Characterization
of Dip
Synthesized
Al-B
Co-doped
ZnO
Seeded
Platforms
for ZnO
Nanostructures
Zinc
oxide
and
aluminum-boron
co-doped
zinc
oxide
(Al-B:ZnO)
thin
films
have
been dip
coated
on glass
substrates
using
Sol-Gel
technique.
The ZnO
solution
was
prepared
by using
zinc
acetate
dihydrate
(ZAD) as
starting
material.
Ethanol
and
citric
acid
were
used as
solvent
and
solution
stabilizer,
respectively.
Doping
of Al-B
was
achieved
by
adding a
proper
molar
ratio of
aluminum
nitrate
(Al(NO3)3
9H2O)
and
boric
acid (H3BO3)
to the
final
ZnO
solution.

Size-Fractionated
Number
and Mass
Concentrations
in the
Urban
Background
Atmosphere
during
Spring
2014 in
Amman –
Jordan
WiThe
number
size
distribution
of urban
aerosols
was
never
measured
in
Amman,
Jordan.
In this
study,
we aim
at
investigating
the mean
number
size
distribution
(optical
diameter
0.3–10
µm) and
size-fractionated
particle
number
and mass
concentrations
during
spring
2014 in
the
urban
background
atmosphere
of
Amman,
Jordan.
