The comparative analysis of the excitation function of Uranium-238 was
carried out using a Coupled-Channeled Optical Model code, OPTMAN. The
high demand for nuclear reactor fuels has necessitated this research. As one of
the major naturally occurring radioisotope of Uranium with lots of fuel prospect,
Uranium-238 occur in large quantities (99%). Two steps process away from
Uranium-238 on neutron capture can produce fissile materials to be used as
reactor fuel. Though, Uranium-238 is not by itself a fissile material. But, it is a
breeder reactor fuel. Computations were done for both the Potential Expanded
by Derivatives (PED) which account for the Rigid-Rotor Model (RRM) that
treat nuclei as rigid vibrating sphere as well as account for nuclear volume
conservation and Rotational Model Potentials (RMP) which account for the
Soft-Rotator Model (SRM) that treat nuclei as soft rotating spherical deformed
shapes. Each of the calculated data was compared with the retrieved data from
Evaluated Nuclear Dada File (ENDF) which was found to be in good agreement.
The threshold energies in all cases were found to be 4 MeV for both PED
(Potential Expanded by Derivatives) and RMP (Rotational Model Potentials). It is
observed that results from RMP much better agreed with the retrieved data than
one obtained from PED.

The dys function of kidney dys functions is one of the most common
diseases among people on a global scale. and the renal failure disease
were classvided into five stages, which include decreafe glomerular
filtration rate 60 ml min−1
, levels in serum. The aim of the current
study was to estimate the concentrations of erythropoietin, hepcidin
and albumin in people with chronic renal failure. The current study
included 75 Patients of both gender, ages (40-70). They suffer from
renal failure at different stages which has been classified into five
stages and each stage include 15 sample as well as, 15 healthy
people as a control group. the results showed a significant decrease
(P≤0.01) in the concentration of erythropoietin in chronic kidney disease
(CKD) patients compared with the control group, as the concentration
of erythropoietin began to decrease gradually during the stages of
renal failure due to the decline in renal function in CKD patients as
a result of decreased filtration and secretion of this hormone. The
results showed a significant increase (P≤0.01) in the concentration of
hepcidin in CKD patients, except for the first stage, in which a significant
difference was not observed when compared with the control group.
Finally, the results also showed a significant (P≤0.01) decrease in
albumin levels in patients with renal failure compared to the control
group. Based on the results of the current study, both erythropoietin and hepcidin can be used as indicators of renal failure. Also, albumin is one of the most important criteria for detecting kidney function

In this work, the effects of neutron-induced fissile isotopes of
Uranium, particularly; Uranium-233 and Uranium-235 are studied using
the Coupled-Channelled Optical Model code (OPMAN) code up to 20
MeV. The high demand for nuclear reactor fuels has necessitated this
research. As one of the major naturally occurring radionuclides with lots
of fuel prospect, Uranium-233 occurred in trace while Uranium-235 occur
in 0.71%. Two steps process away from Uranium-233 and Uranium-235
on neutron capture can produce fissile materials to be used as reactor
fuel. Though, Uranium-233 and Uranium-235 are not by them self
a fissile material, but they are breeder reactor fuels. Computations
were done for both the Potential Expanded by Derivatives (PED) which
account for the Rigid-Rotor Model (RRM) that treat nuclei as rigid
vibrating sphere as well as account for nuclear volume conservation and
Rotational Model Potentials (RMP) which account for the Soft-Rotator
Model (SRM) that treat nuclei as soft rotating spherical deformed shapes.
Each of the calculated data was compared with the retrieved data from
Evaluated Nuclear Dada File (ENDF) which was found to be in good
agreement. The threshold energies in all cases were found to be 4 MeV
for both PED (Potential Expanded by Derivatives) and RMP (Rotational
Model Potentials). It is observed that results from RMP much better
agreed with the retrieved data than one obtained from PED.

Some new phenylene bis tetrazole (T1-3) and bis benzoxazepinedione (B1-3) derivatives have been successfully synthesized through cyclization reaction for some bisimines (S1-3). The bisimines were
transferred to heterocyclic compounds by adding sodium azide and
phthalic anhydride to form bistetrazoles and bisbenzoxazepinediones
respectively. The structures of the prepared compounds have been
identified using infrared spectroscopy technique (FT-IR), the proton
nuclear magnetic resonance (1HNMR) and the carbon nuclear magnetic
resonance 13CNMR. Antibacterial effect of the novel compounds
has been evaluated against Staphylococcus aureus (gram-positive
bacteria) and Escherichia coli (gram-negative bacteria). The results
indicated that bistetrazole T1 and bisbenzoxazepinedione B1 showed
the highest inhibition zone against the growth of the applied bacteria.
This may relate to presence of dimethyl amino group (CH3)2N increasing
the potential of bacterial cell attack by the tested compound as this
substituent can behave as donating group. This leads to less resistivity
from bacteria to the tested compound resulting in an increase in the
inhibition zone. Thus, tetrazole and oxazepine derivatives bearing
dimethyl amino group should be considered as antibacterial agents for
drug industry application field.

In real-time monitoring applications where batch calibration approaches cannot be easily performed, the strategy of coupling between
FIA and ISEs in FIA-ISEs is ideal for usage. On the other hand, manual
manipulation of the solutions continues to be the foundation of current
analytical equipment. The automated technique Flow Injection Analysis
(FIA), combined with the urgent requirement for automated approaches,
a significant influence of contemporary characterization methods
are carried out. The flow injection analysis is a method involving
clear operating fundamentals that shows promise. And although the
electrodes are very selective, they are not free, therefore they link with
ion selective (IS) as a detector on Selective Electrodes (ISEs) that
are used to monitor some of the most important analyses on clinical
laboratory and point of care analyzers.
