type: item
description: The Proteus mirabilis. are opportunistic members of Enterobacteriaceae ,accounting for 10% of urinary tract infections and other primary clinical infections. They produce beta-lactamases that can confer resistance to beta-lactam antibiotics. This study aimed to investigate the prevalence of some virulence factors with antimicrobial resistance and molecular characteristics of aac-Ib gene The current study have been included 250 specimens were collected from urine sample, wound, burn, diabetic foot, and vaginal swabs conducted in Baquba Teaching Hospital, Al-Batool Teaching Hospital, and AlKhalis hospital in Diyala province during the period extended from August 2023 to January 2024. A total of 250 specimens Isolates were identified by morphological form on blood agar and macConkey agar, traditional biochemical tests. The results showed that 75 isolates were identified as P. mirabilis (30%) consisted of 35 isolates (46.7%) obtained from urine, 8 isolates (10.7%) obtained from wound, 10 isolates (13.3%) obtained from burns and diabetic foot and 12 isolates (16%) obtained from vaginal swabs. The higher rate of positive isolates were recorded in urine samples. Females isolation rate was much more than in males 60% and 40% respectively and patients age group 21- 30 year was more prevalence than other groups. It was found that the more effective antibiotic against isolates was the norfloxacin followed by levofloxacin, where all isolates were sensitive to it. On the other hand, the less effective antibiotics were amikacin and oxacillin when they were resisted by all isolates.

type: item
description: Thermophilic lipase-producing microorganism’s present important industrial benefits owing to their stability and catalytic activity under extreme environmental conditions. This study sought to isolate and somewhat purify thermostable lipases from thermophilic bacteria collected from geothermal soils in (Hajj Yousef and Qaymawa, Iraq). A total of 68 samples were collected from hot springs at various depths and analyzed for lipase production utilizing tributyrin agar. Promising isolates were identified as Bacillus subtilis, Bacillus thermoleovorans, and Acidithiobacillus ferrooxidans. The lipase enzyme was purified using ammonium sulfate precipitation trailed by size-exclusion chromatography, yielding a 12-fold purification with 65% recuperation. SDS-PAGE revealed a single protein band of ~35 kDa. The enzyme exhibited optimum activity at 70°C and pH 9.0 and retained 85% activity at 80°C and in alkaline pH. Kinetic analysis showed a Km of 2.1 mM and Vmax of 120 U/mg. The enzyme demonstrated substrate specificity toward olive oil and stability in methanol, Ca2+, and SDS. Application trials confirmed 92% conversion of used oil to biodiesel and 80% fat degradation in wastewater. These findings highlight the enzyme's potential in sustainable biotechnology.

The New Stochastic Differential Equations Model for Controlling the Spread of Viral Diseases: HIV as an Example
type: item
description: The main goal of presenting this manuscript is to study the dynamic activities of HIV spread and how to prevent it. The disease behavior was studied by proposing a new stochastic mathematical model. The solution's existence and uniqueness for the proposed mathematical model have been proven. We have also demonstrated the restrictions that must be met for society to rid itself of the scourge of the transmission of HIV by finding the basic reproduction rate. if the basic reproduction rate is less than one this means the disease-free point is stable. Conversely, if the basic reproduction rate is greater than one this means the disease - free point is unstable. The theoretical results were proven numerically through computer simulation using MATLAB.

The Importance of Biochemical Markersin Diagnosing,Managing and Predicting Diabetes Mellitus
type: item
description: Diabetes is a widespread and intricate metabolic illness marked by persistent high blood sugar because of flaws in insulin production, insulin activity, or both. Current treatments don't address the disease's complete development, and management often fails because individual traits vary. People may experience either a metabolic pathway becoming inactive or over stimulated, which can lead to different levels of blood sugar control. Biochemical markers of this condition are very important for early detection, management, and diagnosis because clinical symptoms alone are often not reliable. The focus of treatment should be on results, including supporting mental health care. Diabetes is growing around the world, especially in developing regions where healthcare access is spotty. Therefore, investigating how precision medicine, along with biometrics and biochemical data, can augment existing methods is of value. These sources of data could improve health outcomes and reduce future problems. Samples were taken from patients from several hospitals in Diyala Governorate: Baquba Teaching Hospital, Al-Zahraa Hospital, and Al-Khalis Hospital. This investigation included 90 patients with various forms of diabetes (T1DM, T2DM, and gestational), aged 25 to 70, with a male to female ratio of 38/52. The distribution of diabetes types was as follows: T2DM (47/90), T1DM (17/90), and gestational diabetes (26/90). Sample collection took place over 10 months. This investigation sought to examine diabetes cases and the function of biochemical markers (HbA1c, LDL, and triglycerides) along with biometric variables (body weight and BMI) in creating specific treatments. The results showed better blood sugar control and lowered heart issue risk. Treatment plans considering individual biochemistry helped lower blood sugar and reduce body inflammation. Doctors may improve patient care by creating plans based on individual needs, rather than using a standard approach. The findings suggest that…

Appraisal the Importance of Dehydroepiandrosterone, Metabolites, and Genus Aspergillus in Cancer research
type: item
description: Steroids are natural compounds found in animals, plants, fungi, and some bacteria. Microbial transformation plays a critical role in the biotransformation of steroids, enabling the production of compounds with high regional and spatial selectivity. Cancer remains one of the most significant scientific challenges, causing millions of deaths each year. Consequently, major research efforts are focused on discovering new therapies, particularly due to the emergence of certain fungi that exhibit anticancer properties, which could lead to innovative treatments. Metabolites, which are intermediate products of biochemical processes in living organisms, are essential for clinical diagnosis. Therefore, accurate detection of their concentrations is crucial. In this work, I will describe an experiment published at the 1st International Karatekin Science and Technology Congress, held from September 1-3, 2022 in Çankırı, Turkey. The aim is to clarify the inputs, outputs, and processes to enhance the understanding of the key concepts discussed here. The experiment focused on incubating dehydroepiandrosterone (DHEA) with Aspergillus glaucus, which primarily resulted in the production of several hydroxylated metabolites. Discussing this experiment as one of the experiments that produces metabolites as a result of the biotransformation of steroids may have a major role in the development of promising treatments for cancer.

Evaluation of the Proposed Hand Vein Authentication System using Machine Learning
type: item
description: This paper discusses the use of a biometric system for secure authentication based on deeper exploration in hand vein patterns to derive more reliability as a good biometric trait. The proposed system identifies internal hand vein patterns, and also identifies individuals correctly throughout their lifetime. The proposed system follows a three-phase approach comprising data processing, feature extraction, and feature evaluation. For the advanced filtering techniques in a dataset of 420 hand vein images, the approach goes to Box filters, HFEF, and CLAHE, then to discrete cosine transformation and image fusion. The features are extracted through PCA Net for acquiring the most distinctive attributes of hand veins. The different machine learning algorithms used in this evaluation for classification of the extracted features include SVM, Logistic Regression, and Naive Bayes. Results indicate highest accuracy for Logistic Regression algorithm (99.7%) and SVM algorithm of (99.6%). However, Random Forest algorithm has an accuracy of (98%), while Naive Bayes algorithm shows poorer accuracy of (91%).

A Numerical Study of Linear Two-Points Boundary Value Problems with ODEs of Fourth-Order Using RKM Method
type: item
description: This study established the numerical RKM approach for solving linear two-point boundary value problems involving fourth-order ordinary differential equations. However, the proposed developed numerical RKM method has been tested using some implementations in order to compare it with the exact solutions to establish the method's validity. Furthermore, this comparison demonstrates that the proposed direct integrator is more efficient than the indirect method in terms of efficiency and accuracy. In addition, numerical implementations are used in order to show the efficiency and time-based complexity of function evaluations. This direct method's suggested strategy, which has wonderful qualities like quick and efficient calculation, also requires fewer computational employees.

Relation between Renal Function and Insulin Resistance of Type 2 Diabetic Iraqi Patients
type: item
description: Type 2 diabetes mellitus (T2DM) is a condition where the body's ability to regulate and utilize glucose as fuel is compromised. As a result of this chronic ailment, excess sugar circulates in the bloodstream. Thus, it can be described as a cluster of metabolic disorders that manifest through factors like insulin resistance and give rise to various complications. These conditions impact several physiological organs, leading to reduced efficiency in their functioning. The objective of this study was to assess the level of insulin in patients with Type 2 diabetes mellitus (T2DM) and to interpret the relationship between insulin resistance (HOMA-IR) and renal function. The methods employed in this investigation were designed to achieve these specific aims, seventy patients and twenty controls were involved for this study. The patients of T2DM was divided into three group according to them eGFR, 20 stage I patients (G1), 25 stage II diabetic patients (G2) and 25 stage III diabetic patients (G3). Insulin, fasting plasma glucose (FBG), HbA1c, and renal function were measured in all subject. The study's findings indicated that patients in Group 3 (G3) with elevated glomerular filtration rate (GFR) exhibited significantly higher insulin levels (14.48 μIU/ml) and HOMA-IR values (8.66) compared to other patients. Moreover, diabetic patients had significantly higher serum insulin levels than those in the healthy control group (P<0.001). The diabetic group also demonstrated a marked degree of insulin resistance compared to the healthy control group. Additionally, a negative correlation was observed between HOMA-IR, eGFR, and Duration in the diabetic patients. Conclusion: higher insulin levels and insulin resistance appear to contribute to the development of chronic kidney disease (CKD).

Intelligent Antenna Array Systems for Modern Communication Networks
type: item
description: In last two decades, Smart Antenna Systems (SAS) as well as Multiple Input Multiple Output (MIMO) systems have emerged as strong and efficient contenders for 5G wireless communication networks due to the advantages they may bring based on the improvements in transmission and reception of electromagnetic signals with respect to omnidirectional antennas. Although there is a fair amount of academic software previously available in this field, cross-use systems simulators do not utilize sufficient wireless system requirements to implement all requirements, and therefore, they do not provide the opportunity to emulate on the broadest lines where SAS or MIMO is more widely used. In this work, a new idea will be formed to improve MIMO 5th generation (5G) smart antenna using adaptive equalizer technology. This new proposal will appear distinctly and noticeably to improve the performance and efficiency of transmission and reception, in addition to its high sensitivity.

Effect of DNA Damage on the Development of Diabetes Mellitus due toIonizing Radiation Exposure
type: item
description: Exposure to ionizing radiation destroys several biological processes by disturbing the membranes of cells and causing damage to DNA, proteins, and mitochondria. Increasing the use of ionizing radiation-based treatment and diagnosis techniques has been associated with the increased chronic diseases among healthcare occupational and patients. However, numerous factors such as duration of exposure, radiation dose, dose rate, the organs of the body exposed, and the person's age impact the ionizing radiation-induced chronic effect. Exposure to ionizing radiation has various harmful effects on healthy tissues; long-term exposure to radiation increases the risk of carcinogenesis and autoimmune diseases such as diabetes. A recent study has also highlighted its potential role in the development of diabetes. This review examines the linkage between radiation-induced DNA damage and diabetes and Explores how radiation can contribute to the emergence and worsening of this chronic metabolic disorder. This review study aims to offer an exhaustive summary of how radiation-induced DNA damage promotes diabetes hazards, highlighting areas for future studies. Also, taking oral antioxidants to protect from radiation-induced DNA damage and mitigate oxidative damage and inflammatory markers after radiation exposure may reduce the incidence of diabetes. Radiation can cause damage to DNA through ionization, which creates free radicals that attack the DNA structure, leading to mutations or breaks in the DNA strands. If this damage occurs in cells involved in glucose regulation or insulin production, it may contribute to the development of diabetes.

description: In this paper, we extended some numerical methods to solve fuzzy integro differential equations. The considered problem involves the fractional Caputo derivatives under some conditions on the ordered. As we combine Euler's method with composite Simpsons have been used to determine the solutions of these equations. We extend these numerical techniques to find the best solutions. Extended difference Euler technique is used for this. The results show that the extended Euler method is more accurate in terms of absolute error. Illustrative examples are given to demonstrate the high precision and good performance of the new class.

Synthesis of ZnO: Cu and Ag Bimetallic Nanoparticles by Laser Ablation
type: item
description: Nanoparticles (ZnO: Ag and Cu) were prepared using the pulsed laser ablation method in liquid. The prepared samples were characterized by X-ray diffraction patterns (XRD), particle size analysis (PSA), UV-visible spectroscopy, and Zeta potential (ZP). the JCPDS standard card for Zn (01-080-0074) validated the hexagonal ZnO structure by X-ray diffraction for (ZnO) and (ZnO: Cu and Ag). we calculated the average crystal size of all the produced samples, and we observe that the crystal size grows as the ratio of copper and silver doping rises. The UV-VIS results showed excellent absorption bands of 290–345 nm, confirming that the Ag-containing nanocomposites absorb visible light. As a result, the spectral absorption band of pure ZnO widens with the adding of Cu and Ag, and the absorption edge moves towards a longer wavelength. This significant increase in absorption in the visible region indicates that the generated nanocomposites can reach a more significant catalytic activity in the visible region. The energy gap value decreases, namely 2.97, 2.90, 2.87, 2.79, 2.65, and 2.488 eV, respectively, due to the increasing doping ratio of silver and copper. ZP data of colloidal solutions containing (ZnO) and (ZnO: Ag and Cu) nanoparticles exhibits negative values indicating increased stability of the nanoparticles. However, the ZP data was found to be dependent on the concentration of the surfactant, with an increase in the zeta potentials value corresponding to an increase in the concentration of the surfactant. The PSA results showed promising outcomes and the absence of nanoparticle agglomeration. The synthesized particles were analyzed using FESEM and IMAGE J software to indicate if the particles were nano-sized. Additionally, the particles spherical and quasi-spherical shapes were investigated and found to be of minimal nanoscale size.

Evaluation of the toxicity of the aqueous extract of Ganoderma applanatum (Persoon) Patouillard (1889)
type: item
description: Plants and fungi, are widely used around the world as a source of traditional medicine and human food. Nowadays, scientists and nutritionists encourage the use of plants and fungi although cases of poisoning are frequently reported. Many countries around the world, including the Democratic Republic of the Congo, use Ganoderma applanatum mushroom for its proven therapeutic virtues. However, the people of Sankuru have often suspected it of being poisonous. The purpose of this work was therefore to verify the supposed toxicity of this mushroom. For this, a chemical screening was carried out on the test tubes containing methanolic and aqueous extracts, followed by a screening by thin layer chromatography in order to detect the presence of secondary metabolites. The aqueous extract was administered to mice at doses ranging from 5000 to1000 mg/kg to assess the toxicity of the G. applanatum sample. Examination of Alanine amino-transferase (ALAT) and Asparate amino-transferase (ASAT) in the blood showed no resistance and no alteration of vital organs (liver and heart) even at the highest dose (5000mg/kg). The results of the chemical screening revealed the presence of various compounds, including alkaloids, terpenes, flavonoids, phenols and others. The administration of the different doses did not cause any lethality to the animals used. The results of this study argue in favor of its safety in the traditional treatment of certain diseases by oral route.

Physical Characterization of Cu2basns4 Thin Films Deposited At DifferentConcentrations of Sulfur Ions by Chemical Spray Pyrolysis Method
type: item
description: In this work, Cu2BaSnS4 thin films were deposited on soda-lime glass by the chemical spray pyrolysis technique (CSP) at different concentrations of thiourea, with a thickness of about 350 ±10 nm measured by the gravimetric method. The thin films structural and morphological properties were investigated using X-ray diffraction (XRD), Raman spectroscopy, Field Emission Scanning Electron Microscopy (FE-SEM), and Atomic Force Microscopy (AFM), as well as optical properties using a UV-Vis spectrophotometer at the wavelength range (300–900) nm. We investigated the electrical properties using the Hall effect. Optical band gap of CBTS thin films increased from (1.757 to 1.923) eV when concentrations of thiourea increased from (0.04 to 0.12) M. The Cu2BaSnS4 (CBTS) films have a high absorption coefficient (α > 104 cm-1), indicating allowed direct electron transmission. XRD measurements of Cu2BaSnS4 (CBTS) films revealed a trigonal crystal structure. The XRD pattern preferred the (104) orientation, which has a high intensity and indicates that crystallization is most likely to occur along this plan. Raman spectroscopy of CBTS thin films revealed a protruding peak at ~341 cm-1. The morphological findings and FE-SEM photographs of the thin film surface revealed a variety of structures and forms, one of which resembled cauliflower. Electrical tests revealed the conductivity of (p-type). The calculated electrical conductivity of CBTS thin films was found in the range of 0.053 - 0.184 (Ω.cm)-1. Based on our findings, the Cu2BaSnS4 (CBTS) thin films look to be an excellent choice for an absorber layer in solar cells.
