A global scientific study found that reducing the excessive and indiscriminate use of antimicrobial medicinal drugs in all their forms significantly improved food safety. We made aqueous and organic extracts (Ex1, Ex2, and Ex3) from two plants (Origanum majorana and Matricaria chamomilla) to create the best alternative form for antimicrobial preventive agents that cause food spoilage. Traditional methods determined the most essential compounds in plants, and we used the FTIR analysis technique for all treatments to observe impurities such as glycosides, alkaloids, flavonoids, carbohydrates, and phenolic substances. This study points to synergistic activity for plant extracts (Origanum majorana and Matr

Manganese dioxide nanoparticles were synthesized by the green method using leek with Manganous Sulphate Monohydrate, (MnSO₄.H₂O) in an environmentally friendly manner. The obtained MnO₂ particle was characterized by x-ray diffraction (XRD), field scanning electron microscopy (FESEM), atomic force microscopy (AFM), and (UV-Visible) spectroscopy. The X-ray diffraction pattern showed peaks belonging to manganese oxide nanoparticles; 34.07 nm is the average crystalline size. From the field-scanning electron microscopy (FESEM) image, the surface morphology shows that the nanoparticles are spherical and rocky in shape. An atomic force microscopy (AFM) atomic force microscope was used to show MnO_2<

In this paper, we investigate a mathematical model of hematopoiesis, a process responsible for the regular replacement of circulating blood cells. Since differential delay equations are difficult to control analytically, numerous studies have considered the models as difference equations. The main objective of this work is to provide the necessary and sufficient conditions for oscillation. We address our problem mainly on the basis of oscillatory behavior. Moreover, the latest findings on the qualitative behavior of the biological mathematical model of discrete hematopoiesis are taken into account. More specifically, we explain the mathematical differential equation of discrete hematopoiesis. Moreover, certain significant, necessary and

Baghdad is considered one of the most crowded cities, and it is the location of all government institutions, making it a destination for people from all other provinces. This results in increased traffic density, which in turn leads to increased emissions that contribute to air pollution in the form of gases and particulate matter. This study was conducted from July to December 2022 in the Karkh district of the city, where the Salahuddin highway was divided into five sites based on the presence or absence of plant barriers on either side of the road. PM₁₀ and PM_2.5 pollutant concentrations and climatic factors were measured at each site during morning and afternoon peak hours. The study found that concentrations exc

Nuclear energy levels in  with modest occupancy of the fp-LS shell have been studied within shell model calculations. The interactions used to determine the nuclear energy levels are FPD6, KB3G, and FPY using the fp shell and d3f7cospn for 1d3/21f7/2 model space. Results are compared with each other, and with the existing experimental data, there is clear agreement with some results. Aside from the excellent agreements in the replicated values of energy levels scheme, using model space interactions is the best-fitted two-body matrix element in the fp shell model space. Particularly below 3MeV, the overall estimation of the replicated data is excellent. The wave vectors and analysis are represented in the so-called diagrammatic notation,

     In this paper, based on a linear relationship between the natural logarithms of the scale parameter and dose, nineteen models are constructed using the modified Weibull statistical model to describe the relationship of dose-response and time for multivariate dual-response life experiments with two-replicate. The real biological data set is considered to evaluate the response rates of breast cancer cells treated with the therapeutic zinc selenide prepared in two different ways (physically and environmentally/organically). The unknown parameters are estimated using two estimation methods. The mean square error is used to select the best model. The median lethal dose is then determined on the basis of a new formula at s

   The excessive and unwarranted use of pesticides at different stages of crop production can pose a great danger to the aquatic environment, and particularly to fish. Haematological parameters are indicated to be important for environmental pollution. Blood parameters respond to low doses of pollutants, so hematological changes in common carp fish are used for assessing the effects of contaminants. Toxicological effects of Goldate and Alexander individuals combined as a mixture were observed by monitoring hematological parameters in common carp fish. There were 3 concentration groups (1/10, 1/100, and 1/200) for every pesticide (Goldate, Alexander, and mixture of Goldate and Alexander)  exposed to juvenile fish (60–80 gm. in weigh

Recently, it has been revealed that Toxoplasmosis may be associated with some factors related to type 2 diabetes, such as glucose, insulin, the Homeostatic Model Assessment for Insulin Resistant (HOMA-IR), and Fatty acid binding protein (FABP). Therefore, the current study aimed to specify how Toxoplasma gondii (T.gondii) infection affects glucose, insulin, HOMA-IR, and FABP among adolescents. From October to December 2022, this study was carried out at Al Madain Hospital in Baghdad. For a group of adolescents visiting the hospital, an ELISA test was performed to check their anti-T.gondii antibodies. Ninety adolescents were selected to participate in the study on the basis of this examination. They were divided

This article presents a comprehensive theoretical study of the electronic properties of tin oxide (SnO₂), with a particular focus on its band structure and carrier mobility. Through the utilization of density functional theory (DFT) and advanced computational methods, we delve into the intricacies of the electronic behavior of SnO₂ . By solving the Schrödinger equation and the Kohn-Sham equation, we calculate the electronic energy eigenvalues and wave functions, which provide valuable insights into the band structure, effective mass, and carrier mobility of SnO₂. Our findings contribute to a solid theoretical foundation for further experimental investigations and technological advancements in this field.

In this work, gold nanoparticles (AuNPs) were created utilizing a plasma jet method and 0.5 gm/mol of gold salts (4H2O•HAuCl4) with varied flow diameters (0.6 mm, 0.8 mm, 1 mm, and 1.2 mm). The gas flow changes according to the system diameter (2,2.4,3.4, and 3.6 L/min, respectively). X-ray diffraction, ultraviolet, visible spectra, and FESEM were each used to investigate the nanoparticles. The XRD pattern revealed that the film's extreme peaks reflect crystallinity, with an average crystallite size of (18–26) nm and a face-centered cubic structure. The surface plasmon resonance for colloidal AuNPs produced in the UV was at 536–540 nm.A field emission scanning electron microscope (FESEM) was used to look at the morphology of the Au
