Nickel-doped manganese–magnesium ferrite (Ni_xMn_0.25-xMg_0.75Fe₂O₄) was prepared using the auto-combustion method. X-ray diffraction patterns showed a single ferrite spinel phase in all the prepared samples. The crystallite size ranged from 24.30 to 28.32 nm, increasing with increasing the Ni content. The porous structure of all the samples was verified with a scanning electron microscope. FE-SEM images were used to confirm the production of spherical or semi-spherical nanoparticles with little change in particle size distribution. The study revealed that the nanoparticles were small enough to behave superparamagnetically. According to the magnetic tests conducted with the VSM at roo

This research aims to assess trace elements of contamination by agricultural soils in the Al-Haye district. Soil samples were collected from a selected agricultural area near the banks of the Tigris River, and trace elements (Ag, As, Ba, Cd, Co, CR, Cu, Fe, Hg, Mn, Ni, Pb, Se, V, Zn, Zr, Pb, Se, V, Zn, Zr), pH, electrical conductivity, and organic matter were identified in soil samples. The pH of the soil sample ranged between 7.7 and 7.6, which is equivalent to the pH of the sub-alkalis (7.3). The organic matter content is 1.8433%; this range of organic matter is between 1.56 and 1.98. The average soil conductivity was 995.37 ug/cm. The level of trace contamination was found in soil samples as follows: Fe> Mn> Ba> Cr> Ni>

Because of the importance of using ^99mTc isotope as a radioactive tracer for nuclear medicine, the production of this isotope from accelerating protons at energies 1-70 MeV is investigated carefully through the evaluation of the calculated excitation functions of the ¹⁰⁰Mo(p,2n)^99mTc reaction. For accuracy, the proton interaction channels with ¹⁰⁰Mo, the excitation functions of reactions,¹⁰⁰Mo(p,2n)^99mTc, ¹⁰⁰Mo (p, pn)⁹⁹Mo, and ¹⁰⁰Mo (p, nonelastic) are calculated, using Kalbach Systematic approach in Exciton model gathered with Feshbach-Kerman-Koonin (FKK) statistical theory. The results are compared with the available published data in th

In the oil and gas sector of Basrah, natural radioactive materials are accumulated in various equipment like wellheads, pumps, and separation vessels, often manifested as scales, sludge, and other forms of waste. Without proper preventive measures, these accumulations pose significant risks to workers, the public, and the environment. This study aims to assess the lifelong cancer risks associated with production processes and the handling of resultant waste, be it scale sediments, sludge, or soil. Sample collection across different regions was based on the evaluation of production and storage facilities. Using a high-purity germanium detector (HPGe), activity concentrations of ²²⁶Ra, ²³²Th, and ⁴⁰K were m

    The United Nations classified Iraq as one of the most vulnerable countries to climate change. Temperatures continue to rise leading to more heat waves, droughts, sandstorms, and desertification. This study aims to investigate the characteristics of heat waves over Iraq from 1982 to 2050 using CMIP6 model at RCP4.5 scenarios. The results clearly showed that the effects of climatic changes were evident in the maximum and minimum temperatures inside Iraq. Average temperature increased of 1.9°C between 1982 and 2020. During 1999, there was a sharp increase in summer days for all stations. The annual number of summer days for the stations (Basra, Nasiriyah, Baghdad, Rutba, Sulaymaniyah, and Mosul) was (195, 193, 177, 108, 106, and 142

The study aimed to address the global challenge of cancer-related fatalities by investigating the feasibility of identifying or predicting the early-stage presence of three distinct forms of cancers, colon, thyroid and urothelial carcinoma, via the analysis of raw DNA sequences. The data, sourced from the NCBI database, underwent a series of pre-processing techniques, including kmer analysis, under-sampling and count vectorization. Subsequently, machine learning algorithms, including logistic regression and multinomial Naive Bayes, were implemented on the pre-processed data with logistic regression demonstrating superior accuracy of 80.10% with calibration and 78.54% without calibration. To enhance the model's extrapolative capabilities,

To examine the total mass of the merging galaxy NGC1614, the findings of this paper are presented in the CO(3-2) transition using the Atacama Large Millimeter/submillimeter Array (ALMA). The total mass of the NGC1614 galaxy is determined in this study within a radius of 0.5 kpc, which is based on the line-of-sight rotational velocity. According to the findings, the total mass is about (2.8±0.08)×10⁹ M⨀. The derived mass of NGC 1614 is an important feature to know its mass distributions and dynamical structure. The latter might be a key to study the missing matter mass and stellar mass, where baryonic mass and missing matter in each galaxy become affected by the approaching galaxy during the merger.

The main objective of this topic is to define new types of filters in algebra, such as filter and complete filter. Some theorems that establish the link between these filters were also presented and validated. Any filter in algebra is shown it is a complete filter. Furthermore, regular algebra is demonstrated as a new class of algebra. Additionally, this study introduces two new concepts such as complete ideal and normal. Also, any normal in regular algebra is demonstrated that it is a subalgebra. In addition, the connections between the complete ideal and the subalgebra is investigated. However, some instances are provided to clarify and bolster our results and findings.

In this study biofilm matrix proteins (BMP) were isolated from bacterial biofilm and incorporated in a delivery system (liposome) to stimulate an immune response against virulent pathogens. The specimens were cultured and identified depending on morphological and biochemical tests . Around 67.74% of isolates were found to be biofilm formers. The immunomodulatory activity revealed that BMP-liposome vaccine and BMP vaccine significantly increased chemokine CXCL5 levels in sera of rats in first and second doses. The concentration of total WBCs count, neutrophils, and lymphocytes also increased. In rats groups that had received BMP-liposome vaccine, the challenge test revealed high immunogenicity and effective protection. It can, therefore,

Radioactive waste management is a fundamental issue when using nuclear energy. Therefore, it is necessary to study the health and biological effects on human and environment that these radionuclides cause.  The aim of the present study is to estimate the radiotoxicity for radioactive waste in stocked soil in Al-Twaitha city.  The radiotoxicity was calculated for each radionuclide, present in the waste, using their dose factor due to ingestion, which is given by the International Commission on Radiological Protection (ICRP) compendium.

For the purpose of calculating radiation toxicity, a scenario was built that 20% of the radioactivity during radioactive waste handling processes is in the form of dust that can be inhaled or enter

Image fusion is the process of combining multiple images to obtain one image with complementary information. Hence the importance of multimodal medical image fusion, which aims to obtain all the important information in one image to improve diagnosis in the medical field. The wavelet transform is a mathematical tool for multi-resolution analyses where the images are decomposed into a series of subbands. Wavelet transforms have a good representation of the original images. The averaging fusion rule and shift variance in the discrete wavelet transform, on the other hand, make the image that comes out of fusion under the wavelet transform blurry or of low quality. In this paper, two novel methods have been presented to improve the quality o

It has been revealed previously that chronic liver disease (CLD) may be associated to hormonal fluctuations. The current study, therefore, aimed to evaluate some hormones in CLD patients compared with non-CLD individuals. This case control study was conducted at Gastroenterology and Hepatology Teaching Hospital, Medical city, Baghdad, Iraq during December 2021 to May 2022. One hundred and twenty male patients with CLD (age:14-75 years) and 120 control males (age: 24-70 years) were involved in this study. Serum samples were taken from all individuals and were then analysed for many tests which included hormones (Cortisol, testosterone, prolactin, insulin  and thyroid stimulating hormone TSH); biochemical analysis (Prothrombin time PT, i

Attention-Deficit Hyperactivity Disorder (ADHD), a neurodevelopmental disorder affecting millions of people globally, is defined by symptoms of hyperactivity, impulsivity, and inattention that can significantly affect an individual's daily life. The diagnostic process for ADHD is complex, requiring a combination of clinical assessments and subjective evaluations. However, recent advances in artificial intelligence (AI) techniques have shown promise in predicting ADHD and providing an early diagnosis. In this study, we will explore the application of two AI techniques, K-Nearest Neighbors (KNN) and Adaptive Boosting (AdaBoost), in predicting ADHD using the Python programming language. The classification accuracies obtained were 96.5% and

Chronic kidney disease (CKD) is a serious threat to global medicine as more than two million get CKD yearly. However, the understanding of DNA damage, DNA methylation in chronic kidney disease (CKD) remains elusive. The study goal was to establish whether homocysteine (Hcy), oxidative DNA damage (ODD), glutathione peroxidase (GPX3) and 5-methylcytosine (5mC) could be used as a potential marker of CKD. Measurements of Hcy, ODD, and GPX3 levels were done by commercial enzyme linked immunosorbent assay (ELISA) kits of 60 patients with chronic kidney disease (age range 20-87 years) and 30 age-matched healthy controls. DNA extracted from blood of patients was used to evaluate the global 5-methylcytosine (5mC) levels by the MethylFlash

 In this paper, we have presented a new formula by applying the conjugacy condition for the second-order Taylor expansion. In comparison with classic conjugate gradient methods, the new formula uses both available gradient and function value information. The formula's global convergence findings are described. Numerical results demonstrate that this strategy is effective and its application.

This work includes the synthesis of new pyrazoline derivatives 5-13 over three steps starting from 1,3-indandione. The first step included the acylation of 1,3- indandione with acetyl chloride to produce compound 1 with excellent yield (90%). In the second step, the enolate form of 1 was condensed with various aromatic aldehydes (benzaldehyde, p-nitrobenzaldehyde, and p chlorobenzaldehyde) to afford the corresponding α,β-unsaturated carbonyl derivatives 2-4 in high yields (93-95%). The third step involved a reaction of 2-4 with hydrazine hydrate, phenyl hydrazine, and p-nitrophenyl hydrazine to give the desired pyrazoline derivatives 5-13 in yields ranging from 70 to 83%. The structure of the synthesized compounds was verified through

Many previous studies have demonstrated the therapeutic importance of chondroitinase ABC encoded by the chABCI gene. This study, however, accomplished to determine some amino acids effects on the chABCI gene in Proteus mirabilis to regulate chondroitinase production. A total of 57 (96.61%) isolates of Proteus mirabilis and two (3.39%) isolates of Proteus vulgaris were obtained from clinical specimens. The impact of amino acids on bacterial growth was assessed by gauging the turbidity of the nutrient broth using a spectrophotometer. Two isolates of P. mirabilis were treated with amino acids and their effect on the gene expression of the chABCI gene was studied using a real-tim

Recently, attention has turned to drugs like salicylamide for treating COVID-19. Several studies have reported simple, fast, and sensitive methods for measuring salicylamide levels. However, potential limitations remain regarding interference from other drugs and accuracy of results. To tackle this issue, researchers combined the standard addition technique with flow injection analysis. As part of this investigation, the reaction involving Fe (III), salicylamide, and 1,10-phenanthroline at a temperature of 55°C was examined using a spectrophotometer set at a wavelength of 528 nm. Thus, the new design was able to show an excellent linearity over the concentration range of (2-30 μg/mL) and (25-300 μg/mL), with correlation coefficients (

The lowest layer of the atmosphere is called the atmospheric mixed layer, characterized by small-scale, irregular air motions defined by winds that change in speed and direction. Aerosol radiative effects impact the atmospheric boundary layer (ABL), which holds most aerosols in the lower atmosphere. Aerosol absorption and scattering both lower the quantity of solar energy that reaches the ground, which has an impact on the spectral signature of the land coverings. In this study, 51 locations in downtown Baghdad were chosen for four different types of land cover (water bodies, farms, open areas, and residential areas) for Sentinel 2 satellite imagery, and the time the pictures were taken was 8:00 am ( 22 March, 22 June, 20 September, and

Vitamin D deficiency has been linked to several conditions, including type 2 diabetes. The purpose of this study is to determine if there is an effect of type 2 diabetes on the association between vitamin D level, glycemic indices, and lipid profiles. The study was conducted at Al-Noamman Hospital, included 257 patients with type 2 diabetes and 40 healthy participants of both sexes with matching ages ranging from 26 to 80 years. The lipid profile, postprandial glucose (PPG), HbA1C, and serum vitamin D were measured. The results showed that 89 (34.6%) of diabetics have vitamin D insufficiency (less than 30 ng/mL). 155 diabetic patients (uncontrolled glycemic) with elevated HbA1C (9.07% ± 2.5), and from those, about 33.5% have vi

This paper focuses on the study of pure Rickart modules (or PR-modules for short), which are a class of modules over a commutative ring with identity. The main objective is to investigate the properties and characterizations of these modules, as well as their relationship with other classes of modules such as free, projective, and flat modules. This paper also explores the connections between PR-modules and various algebraic structures such as rings. The results obtained in this study provide a deeper understanding of the structure and behavior of PR-modules, which can have important applications in algebraic geometry, representation theory, and other areas of mathematics. Some results about PR-module have been investigated in this paper

Due to its association with hepatocellular carcinoma and being one of the ten most common malignancies worldwide, hepatitis C viral infection has become a severe public health concern. Therefore, establishing an accurate, reliable and sensitive diagnostic test for this infection is strongly advised. Real-time polymerase chain reaction (PCR) has been created to achieve this purpose. The current study was established to investigate the hepatitis C virus among Iraqi patients with chronic renal failure and to detect the virus immunologically by the fourth generation enzyme-linked immunosorbent assay technique and molecularly by real-time PCR. As a result, out of 50 patients with chronic renal failure undergoing dialysis, 39

In this paper, the integrability and a zero-Hopf bifurcation of the four-dimensional Lotka-Volterra systems are studied. The requirements for this kind of system's integrability and a line of singularities with two zero eigenvalues are provided. We identify the parameters that lead to a zero-Hopf equilibrium point at each point along the line of singularities. We show that there is only one parameter that displays such equilibria. The first-order averaging method is also employed, although this method will not give any information about the bifurcate periodic solutions that bifurcate from the zero-Hopf equilibria.
