Non-Resonant Reaction Rates of 13C(α,n)16O and 22Ne(α,n)25Mg reactions in AGB Stars

Both 13C 16O and 22Ne 25Mg reactions perform a cosmic role in the production of neutrons in AGB stars, which significantly contributes to the nucleosynthesis via the s-process. The astrophysical S-factor for both reactions is calculated in this research, utilizing EMPIRE code and depending on two parameter sets for the optical potential. These datasets were published earlier by McFadden and Satchler (denoted here as MFS) and Avrigeanu and Hodgson (denoted as AH) for the non-resonant region of the spectrum and over a temperature range of . The extrapolated S-factor at zero energy is derived to be  and  for 13C 16O, while the values were  and  for 22Ne 25Mg, using MFS and AH parameter sets, respectively, which showed a reasonable agreement with the most recommended value. The differences in the S-factor, S(E), values obtained from these two adopted parameter sets are attributed to the variations of the real potential term's diffuseness parameter that affects the reaction cross section, hence S-factor, specifically at low energy region. Moreover, the present results imply an influential enhancement of the rates by the electron shielding effect at the low-temperature region  in which 13C 16O reaction is activated,  especially on 22Ne 25Mg reaction. In addition, for both adopted reactions and overall selected temperature range, the reaction rates using  values based on MFS showed acceptable results compared with previous compilations and reference libraries. While the results obtained from AH exceeded all the other compilations even though the resonance contributions are currently unconsidered.

Statistical Analysis of COVID-19 Data in Iraq

The analysis of COVID-19 data in Iraq is carried out. Data includes daily cases and deaths since the outbreak of the pandemic in Iraq on February 2020 until the 28th of June 2022. This is done by fitting some distributions to the data in order to find out the most appropriate distribution fit to both daily cases and deaths due to the COVID-19 pandemic. The statistical analysis includes estimation of the parameters, the goodness of fit tests and illustrative probability plots. It was found that the generalized extreme value and the generalized Pareto distributions may provide a good fit for the data for both daily cases and deaths. However, they were rejected by the goodness of fit test statistics due to the high variability of the data.<

Local Expression of MMP-7 in Oral Cancer

Background: Squamous cell carcinoma of the oral
cavity (OSCC) is a highly invasive neoplasm. Many
MMPs play role in human cancer invasion and
metastases.
Aim: Estimating The MMp-7 expression level in
HPV-16 positive and HPV-16 negative OSCC
paraffin embedded sections.
Method: Biopsies from thirty three patients with oral
squamous cell carcinoma (OSCC) were obtained and
investigated for the presence of HPV-16 RNA with
the application of ISH and the MMP-7 expression
level using IHC .
Results: Expression level of MMP-7 found to be high
in OSCC sections 29 (87.8%) cases with no
significant difference in its expression level between
HPV-16 positive and HPV-16 negative OSCC cases
p= 1.00.

Immunohistochemical Expression of Bcl3 in Human Breast Carcinoma

B-Cell lymphoma 3 is a putative proto-oncogene that involved in central oncogenic pathways that regulate cell death, apoptosis and metastatic of tumor cells so it could be important as a target to validation as a diagnostic or prognostic marker in these tumors. This study revealed positive expression of Bcl3 in (76.6%) of 47 cases infiltrating ductal carcinoma and (61.7%) of positive were strong positive. These results showed no significant association of immunohistochemical expression of Bcl3 with clinicopathological features as well no relation with immunohistochemical expressions of estrogen rreceptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER-2/neu).

Assessment of Apoptosis in Women Using Oral Contraceptives

The aim of the study was the examination of the effect of birth control pills (Yasmin) on women who utilized the pills by measuring the percentage of apoptosis. The investigation was based mainly on the calculation of the apoptosis percentage of blood lymphocytes in women who used the pills for different durations. The results of the presented study was obtained from 25 women handling birth control pills and 15 women who had not used pills. According to the period of contraceptive pills treatment, the samples were classified into two categories: (2-5) years and (6-8) years. Results showed that the percentage of apoptosis in pills handling women (2-5) years were (7.08%) while the results were (12.2%) in women who used birth control pills

The dualism in the poetry of Ahmed Bakheet

The study of the (dualist antagonism) of a poet, will be determined by the poet's potential, and according to the system of concepts and creativity, and this means that there is a difference between the rooting of the meaning and its roots, and poetic sources by tracking the poets and their attitudes.
Therefore, poetry is a variable function according to the values ​​of the movement, which is the freedom and continuous fuel. With these units of measurement, can measure the dose (Ahmed Bakheet) of freedom and mechanisms of investment, Bakheet (moment) of the time of hair dimensions of the limits of his experience. This is what the researchers will address in their research.

Bio-production of Ethanol in Packed Bio reactor

A lab-scale packed Bio film reactor was used for ethanol production by fermentation of sugar solution using a local
isolated yeast saccharomyces cerevisia and glutaraldelryde on gelating as a covalent bounding agent. In this study four
types of packing in the reactor were used. They are; polypropylene mesh, glass rashig rings, ceramic rashig rings and
glass beads. Glucose solutions were used as substrate with four concentrations; (5, I 0, I 5, 20 g/l). Results show that the
ethanol productivity was increase with increasing sugar concentration. Also it was found that polypropylene mesh
packing give the highest productivity while glass beads gives the lowest productivity. The experiments were conducted at
three temperatur

Investigation of Effecting Parameters in a Turning Operation

        In this study multi objective optimization is utilized to optimize a turning operation to reveal the appropriate level of process features. The goal of this work is to evaluate the optimal combination of cutting parameters like feed, spindle speed, inclination angle and workpiece material to have a best surface quality Taguchi technique L9 mixed orthogonal array, has been adopted to optimize the roughness of surface. Three rods of length around (200 mm) for the three metals are used for this work. Each rod is divided into three parts with 50 mm length. For brass the optimum parametric mix for minimum Ra is A1, B1 and C3, i.e., at tool inclination angle (5), feedrate of 0.01, spindle speed of 120

Possible Role of Interleukin-6 in Rheumatoid Arthritis

Background: Rheumatoid Arthritis (RA) is an autoimmune disease. Many etiological agents are proposed to play a role in its pathogenecity. One of these factors is cytokines such as Interleukin6.
Material & Methods: ELISA method has been used for IL-6 estimation in 75 RA patients in comparison with 61 SLE as patient controls and 39 apparently healthy controls.
Results: This study showed that there was an elevation of IL-6 in the sera of RA patients with high significant differences between RA patients and controls (P< 0.001). Moreover a good correlation between IL-6 level & RF titer were observed. However, for most patients with high IL-6 were shown to be HLA-DR4.
Conclusions: Interleukin-6 play
