SARS-CoV-2 virus(COVID-19), the cause of coronavirus disease, has several variations.Some are thought to be particularly important or have been said to be so, because of their potential for greater transmissibility, Virus pathogenicity has grown, or vaccinations against them have become less effective. These mutations have a role in the COVID-19 pandemic's persistence. The B.1.1.529-Omicron variant, found in many coronavirus cases reported in South Africa discovered late 2021, having a surprisingly great number of mutations which raise a concern toward the spreadablity of this variant and severity of illness in comparison to other corona virus variants as well as the effectivity of the available vaccinations. This review summarizes of the most recent information and the answers to most of the world's questions about Omicron.

Background. Since humanity is attempting to challenge the COVID-19 pandemic by accelerating the production of vaccines against SARS-CoV-2, there could be opposite health side-effects on the participants and researchers. Materials and Methods: Institutions, governments, companies, and organizations around the world work relentlessly to produce drugs and/or vaccines for this disease; yet none were approved. In this work, we are presenting the technologies platforms, developed vaccines, development challenges, and the under-process vaccines. Results: The recent developments in the diagnosis and types of vaccines were also discussed. Conclusion: Many vaccines were invented to stop COVID-19’s spreading using different techniques.

Artificial intelligence algorithms have an important and effective role in the medical field, especially in the field of diagnosing diseases. This research focuses on predicting the diagnosis of gestational diabetes by using the Iterative Dichotomiser3 (ID3) classifier algorithm, which is utilized to identify gestational diabetes; it was one of the most significant algorithms employed in this study. Training and testing are two critical phases of the research study. This study employed the Pima Indians Diabetes dataset, which comprised 768 women aged 21 and abovewith the eight reported traits. A feature selection stage, a discretization step, and using the classifier model for producing decision rules are all part of the Pima Indians diabetes data gathering process (Diabetes Dataset). In this study, the decision tree is employed to develop the classifier model, which is based on Diabetes training. The Iterative Dichotomiser3 (ID3) technique may be used to run the decision tree classification process. Diabetes is tested using decision rules, and the classifier implementation confusion matrix was retrieved from the testing portion. The system delivered high-quality results with a 94 percent accuracy rate.

In this paper the survival function of the Power Lomax distribution is estimated by two methods of estimation, which are the maximum likelihood method and the moment method. The obtained estimators contain non-linear equations that cannot be solved by ordinary mathematical methods and do not represent the estimations clearly, so a simulated annealing algorithm was used to solve this problem, then simulation was used to compare the estimation methods based on the statistical comparison criterion mean squares of integral error (IMSE) and to get the best estimator for survival function. The results show the preference the maximum likelihood method than the moment method.

The Polycystic ovarian syndrome is a feature of the various menstrual cycles, infertility, hormonal irregularities, and hyperandrogenism. Insulin resistance, lipedema and hyper and rogenism are the most widespread endocrine disorder in PCOS. Most half of women with PCOS suffer from hirsutism, weight gain, metabolic syndrome, insulin resistance, hypothyroidism, and dyslipidemia. The Aim of the Study is to measure thyroid function, especially hypothyroidism in women with the polycystic ovarian syndrome and its association with insulin resistance. It also aims to estimate the effect of hypothyroidism on the level of each of the following biochemical parameters: lipid profile, glucose, insulin, anti mullera in hormones, sex hormone and thyroid disorders frequency (hypothyroidism) in PCOS. Subjects, Materials and Methods: This study was performed on patients in the outpatient clinics of the Obstetrics, Gynecology and Infertility Clinic and at the al-Yarmouk Teaching Hospital in 2020, and it included 30 (control group) and 70 patients, including 35 euthyroid PCOS and 35 hypothyroidism PCOS (PCOS group),in the age group 15-45 years. Thyroid hormone levels Thyroxine (FT3, FT4) and Thyroid Stimulating Hormone (TSH), Luteinizing Hormone (LH), Follicle Stimulating Hormone (FSH), Prolactin (PRL), Testosterone, Progestogen, Estradiol (E2),Anti Mullerian Hormones (AMH), Thyroperoxidase Anti Bodies (anti TPO), Insulinwere measured by using a devicecobas e411, and Lipid profile and Glucose by using a devicecobas c311.Results:There was an increase in TSH levels, a decrease in thyroxine, anincrease in lipid profile levels, an increase in the sex hormones levels, increase glucose and insulin resistance which is a sign of diabetes type 2. However, the reverse is noticed in the relation of hypothyroidism on PCOS with weight gain, lipids, insulin resistance, and rogynism and hirsutism. The most frequent thyroid disorders affecting PCOS in this study were found to be autoimmune thyroiditis and hypothyroidism. Conclusions: More than half of the women with PCOS suffer from hypothyroidism, compared to the normal women. As it was observed that dyslipidemia, weight gain, hirsutism, insulin resistance and sex hormones were more in hypothyroidism PCOS women compared to normal control subjects. We also concluded that PCOS and hypothyroidism are interrelated, as the presence of either is a cause of the other and that means the PCOS is more than just oligomenorrhea, amenorrhea, or infertility.

This review highlighted the analysis techniques of hydroxamic acid (HAs) and Organotin (IV) Hydroxamates. Different isomerism, keto and enol form,as well as, intra and inter hydrogen bonding are confirmed through spectroscopic studies. In addition all organotin(IV) complexes geometries were studied and explained in this review depending on different analysis techniques done by researchers. Our study is not unique but it gives your attention to be more concern if you will deal with these types of compounds regarding to the functional groups, isomerism, structural information and its geometry.

The high-temperature superconductor like YBa2Cu3O6.5+was prepared by solid-state reaction method at calcination temperatures (900 °C). The crystal structure was confirmed using X-ray diffraction, and it was found that YBa2Cu3O6.5+showed orthorhombic phase with lattice parameters (a=3.82030, b=3.88548,and c=11.6835 Å) with space group (Pmmm). The sample was sintered at sintering temperatures (900 °C) for (24 hr). The oxygen excess () was nearly (0.36), which was effective in the appearing superconducting properties. The sample YBa2Cu3O6.86 had a critical temperature of about (92 K). The simulation on the XRD-pattern was necessary to predicate the shape of the unit cell and the position of atoms in the unit cell. The last is very important to find some theoretical date, which are benefit in the predication the conductivity parameters through the sequence's unit cells, which are useful in the conductivity mechanism. This mechanism is depending on the concept of interlayer coupling, so the number of the layers including the unit cell is effective parameter in the conductivity mechanism through the normal resistivity created.

This paper suggests and analyses a model consisting of two commensal populations with Michaelis-Menten type of harvesting for the first population. The first harvested commensal species draws strength from the second hosted species. The overall dynamics are provided to achieve the coexistence, stability and persistence of the equilibrium points for the proposed system. The local bifurcation near the positive equilibrium point is attained. Moreover, numerical simulation using MATLAB is investigated to the impact of the commensalism interaction on the behavior of the planned model. The analysis shows that the role of commensalismpr events the first population from extinction, which could be helpful for the survival of both species.
