Coronavirus infection a new infectious illness brought on by the
SARS-COV-2 virus has infected people worldwide as of 2019, a covid-19
disease is associated with hematological and biochemical parameters
changes. The present study aimed to evaluate the possible relationship
between patient parameters and disease severity. A total of 200
nasopharyngeal swabs and whole blood specimens were collected from
individuals suspected of CoV-2 and healthy volunteers as control of both
sexes, grouped into four groups:50 patients for each mild, moderate,
and severe patients and 50 healthy volunteers. The current study
demonstrated that female 82(55%) was more frequently affected than
male 68(45%). Hematological parameters including white blood cell
count (WBC), granulocyte count, and Red blood cell distribution width
(RDW%) (increased significantly p value< 0.05, while Lymphocyte count
decreased significantly when compared with a control group. Significant
differences in hemoglobin concentration, packed cell volume, red
blood cell count, and indices of red blood cell count were shown when
compared with a control group in both sexes. Regarding biochemical
parameters including serum vitamin D, ferritin, D-dimer, procalcitonin
(PCT), and liver function tests, serum vitamin D decreased significantly,
while serum ferritin, D-dimer, procalcitonin and liver enzymes increased
significantly in the covid-19 patients group compared to the control group.
According to vitamin D receptor, gene polymorphism in covid-19 patients
genotype Bb was most likely associated and strongly related to getting
infected with CoV-2 virus with all the three known stages of infection.
Severity of CoV-2 was associated with leukocytosis, lymphopenia and
biomarkers are the best predictors of severe CoV-2, with a strong relation of VDR gene polymorphism BsmI with the severity of CoV-2 patients.

Elastic and inelastic electron scattering form factors for the 17O
nucleus are calculated for the positive parity low-lying states in the
momentum transfer interval 0.05-3 fm−1
in the framework of shell model
and Skyrme-Hartree-Fock calculations. Also, protons, neutrons, mass
and charges root mean square, r.m.s., radii and the charge spatial
density distribution are calculated. The ZBME model space out of 12C
nuclei core with rewile interaction have been used. For all selected
ground and excited states, Skyrme interactions with SkXcsb and
SLy4 parameter, harmonic and Wood-Saxon potentials are adopted in
Hartree-Fock theory to generate the mean potential and hence calculate
the elements of single-particle matrix and form factors. Also, we have
used Tassie model to account for core-polarization effect. Finally, to
check the reality of the calculated values, the charges r.m.s. and form
factors are discussed and compared to the measured values. A good
agreement can be shown by the theoretical results to the measured ones

The conjugated spectral gradient (SCG) method is an effective
method for non-constrained large-scale nonlinear optimization. In this
work, a new spectral conjugate gradient method is proposed with a
strong Wolfe-Powell line search (SWP). The new proposal is based on
using the formula obtained by comparing the proposed algorithm with
previously published conjugate gradient algorithms. Under the usual
assumptions, the descent properties and overall global convergence of
the proposed method are proved. The proposed method is numerically
proven to be effective.

Solid-state nuclear track detectors such as CR−39 are used in the
detection of charged particles and heavy ions. In this paper, the effect
of two types of chemical etching solutions on the etching properties
of the detector CR−39 of 400µm thickness was studied. The etching
properties involved the calculation of the etching parameters which are
the bulk and track etch rates (VB and VT ) respectively as well as the etch
rate ratio (V), and then comparing them for the two types of etching
solution. We used two sets of detectors each piece of dimensions
(1×1)cm2
. The detectors were irradiated with alpha particles of energy
(2, 3, 4, 5) MeV using a 241Am source to obtain tracks of alpha particles
in the detector. To reveal the latent tracks, the irradiated detectors
were treated with aqueous KOH and NaOH solutions. Both groups of
irradiated detectors were etched under the same conditions of different
molarities ranged from (3 − 11) N at temperature (70 ± 1)
◦C for both
solutions for time periods ranging from (3) h. The VB was measured by
the method of removal thickness difference from the detector surface by
etching for the specified periods. By measuring the diameters of the
tracks and the diameter growth rates (VD) for the specified intervals, the
VT and V were measured in correlation with the VB for the both types of
the solution used. By comparing the results, it was appeared that the
etching rates with NaOH solution is greater than that etched with KOH
for VB and VT .

The optical properties of agarose thin films, such as absorption,
absorption coefficient, and extinction coefficient, are presented in this
study. To obtain a 2% wt/v concentration of agarose, 0.2 mg of agarose
was dissolved in 10 mL of water, and the mixture was then heated in the
microwave for 30 second until boiling. In the current investigation, three
types of water were used, including distilled water labeled as W1 (pH =
7.5 and TDS = 18 ppm), Zamzam water labeled as W2 (pH = 8 and TDS
= 339 ppm), and so forth well water with the designation W3 (pH =8.6
and TDS = 1440 ppm). Total dissolving salts (TDS) and pH vary across
the aforementioned types of water. The agarose thin film was irradiated
using a (Nd:YAG) laser with three different wavelengths, including (532,
1064, and 1320) nm. Investigations into the impacts of changing the
laser’s wavelength on the optical characteristics of agarose thin films
were conducted.
