Transport
Theory
of
Muonic
Atoms in
Hydrogen
Isotope
Media
The
resonance
muonic
molecular
formation
is
highly
dependent
on the
energy
of
muonic
atoms.
The
energy
loss of
muonic
atoms
depends
on the
range of
distance
traveled
in a
medium.
The
resonance
molecular
formation
rate for
mdt
is
maximum
if the
kinetic
energy
of the
muonic
atoms
(such as
mt)
which
enter
the D2
medium
is in
the
range of
0.4-0.6
eV. In
this
research,
the
transport
theory
is used
to study
the
effect
of
thickness
of the
suggested
multi-layer
system
(H/T and
D2)
on the
output
kinetic
energy
of the
muonic
atoms,
mt.
The
optimum
thickness
of
multi-layer
system
is also
calculated
for
mdt
resonance
formation.
Finally,
the
obtained
results
of the
used
theoretical
method
are
compared
with the
experimental
results.... |

226Ra,
228Ra
and
40K
Concentrations
in Some
Plant
Seeds
Consumed
in
Jordan
Eleven
types of
seeds
consumed
by
Jordanian
people
were
investigated
to
determine
the
concentration
levels
of
226Ra,
228Ra
and
40K
radionuclides.
The
calculated
concentration
ranges
from
0.214 ±
0.017 to
7.583 ±
0.592
Bq/kgdry,
10.629 ±
0.914
Bq/kgdry
and 92.0
± 7.61
to 576 ±
46.22
Bq/kgdry
for
226Ra,
228Ra
and
40K,
respectively.
The
total
annual
effective
dose
that
resulted
from
consuming
the
selected
seeds by
ingestion
was 35.17
µSv/year,
whereas
the
cancer
risk
ranges
between
1.58×10-6
from
fennel
and
23.53×10-6
due to
beans.
However,
the
average
cancer
risk
value
was
7.74×10-6,
which is
less
than the
world
average
cancer
risk
value
3mSv/year. |

Growth
Inhibition
of
Natural
Foods on
Calcium
Hydrogen
Phosphate
Dihydrate
Crystals
A large
number
of
people
are
suffering
from
health
problems
due to
urinary
stones.
The
prevalence
of
urinary
stones
is
increasing
and
approximately
12,000
patients
are
admitted
in
hospitals
every
year due
to this
condition.
Brushite
[CaHPO4⋅2H2O]
or
calcium
hydrogen
phosphate
dihydrate
(CHPD),
which is
known as
urinary
crystal,
is a
stable
form of
calcium
phosphate.
This
study
aims to
investigate
the
influence
of
natural
foods on
the
formation
of
calcium
hydrogen
phosphate
(CHPD)
crystals
to
elucidate
the
inhibitory
effect
of
urinary
stone
formation
from a
different
perspective.
Natural
foods
used in
this
study
are
Solanum
lycopersicum
(Tomato),
Daucus
carota
(Carrot)
and
Vitis
vinifera
(Grapes).

Photoluminescence
Behavior
of Cu2+xZn1-xSnS4
Thin
Films by
SILAR
Method
Cu2ZnSnS4
thin
films
were
deposited
on a
glass
substrate
by
chemical
method.
The XRD
pattern
confirms
the
formation
of
tetragonal
structure
CZTS and
peak
shift is
noticed
for Cu
doping.
The
absorption
coefficient
is in
the
order of
104cm-1
and the
band gap
is found
to be
about
1.9 eV –
1.75 eV.
The PL
spectra
show red
shift
for
higher
Cu
doping
concentrations.

Dielectric
Relaxation
Studies
on
Binary
Polar
Mixtures
of
Diethylene
Glycol
with
Ethyl
Benzoate
Using
Time
Domain
Reflectometry
It is
interesting
to study
the
nature
of
intermolecular
interactions
between
associative
and
non-associative
polar
liquids.
Dielectric
relaxation
measurements
on
polar-polar
binary
mixtures
of ethyl
benzoate
with
mono
diethylene
glycol
were
carried
out for
eleven
different
concentrations
at
temperatures
(298K,
303K,
308K and
313K)
using
Time
Domain
Reflectometry
(TDR)
over the
frequency
range
from
10MHz to
10 GHz.
The
Kirkwood
correlation
factor
and
excess
dielectric
properties
were
determined
and
discussed
to yield
information
about
the
intermolecular
interactions
in
binary
system.
The
non-linear
variation
has been
observed
in
relaxation
time
with
increasing
of
alcohol
mole
concentration.

Analysis
of the
Force
Exerted
on an
Accelerated
Beam of
Electrons
by Its
Own
Wakefield
in the
Laser-Driven
Rf-gun
Analytical
expressions
for the
wakefield
force
acting
on an
electrons
beam, in
the
RF-photoinjector,
during
the beam
extraction
from the
cathode,
are
derived.
These
expressions
are
obtained
by
taking
space
charge
effects
and beam
motion
into
account.
The
former
is
described
in terms
of the
field's
components
due to
Lienard-Wiechert
potential
and the
method
of
images,
close to
the
cathode
surface.
The beam
motion
is
emphasized
circumstantiating
the fast
transition,
owing to
quick
acceleration
by the
high
gradient
RF-accelerating
field,
from
thermal
velocity,
near the
immediate
vicinity
of the
cathode,
to a
non-relativistic
velocity
at the
end of
the
photoemission.

Synthesis
and
Characterization
of CuMS2
(M= Bi,
Sb) Thin
Films
Prepared
by CBD
Method
CuMS2
(M= Bi,
Sb) thin
films
(0.1 M)
were
deposited
by
chemical
bath
deposition
(CBD)
method
and
characterized
by X-ray
diffraction
(XRD)
and
UV-Visible
(UV)
analyses.
The XRD
pattern
confirms
the
formation
of
orthorhombic
structured
CuBiS2
with Cu2S
phases
as an
impurity
and
orthorhombic
structured
CuSbS2.
UV
studies
show
higher
optical
absorption
in the
visible
region,
which
indicates
that the
resulting
material
can be
used as
an
absorbing
material
in solar
cells. |
