Detecting the antibacterial activity of green synthesized silver (Ag) nanoparticles functionalized with ampicillin (Amp)

In the current study, synthesis and characterization of silver nanoparticles (AgNPs) before and after functionalization with ampicillin antibiotic and their application as anti-pathogenic agents towards bacteria were investigated. AgNPs were synthesized by a green method from AgNO3 solution with glucose subjected to microwave radiation. Characterization of the nanoparticles was conducted using UV-Vis spectroscopy, scanning electron microscopy (SEM), zeta potential determination and Fourier transform infrared (FTIR) spectroscopy. From SEM analysis, the typical silver nanoparticle particle size was found to be 30 nm and Zeta potential measurements gave information about particle stability. Analysis of FTIR patterns and UV-VIS spectroscopy confirmed the production of nanosilver particles. The activity of produced silver NP was tested against three pathogens (Escherichia coli, Staphylococcus aureus, and Acinetobacter baumannii) in both liquid and solid growth medium. AgNPs presented potential antibacterial activity, against tested bacteria. Ag and Ag-AMP nanoparticles were detected to have penitent antimicrobial. The optical density (OD) of the culture solution and measuring zones of inhibition were used to monitor the growth of bacteria in liquid and solid growth medium respectivel

Optimization the Parameters of Hotwire Cutting Process to Enhance the Properties of Polystyrene Foam

Hot –Wire  cutting process is one of the important method to produce different shapes and prototypes of  Extruded Polystyrene (XPS) and Expanded Polystyrene (EPS) material . The study and analysis of Hot-Wire cutting parameters play an important role to enhance the quality and accuracy of the process and products . The effect on the surface has been investigated by using the experimental test which designed according to the Taguchi orthogonal array (OA). In this study, four parameters,(temperature of wire(A) (°C), diameter of wire (B) (mm) , velocity of cutting (C) (mm/min), and density of foam (D)(gm/cm3) , with five levels for each parameter have been used. A full process would require (45 =625) experiments .The design of experiments(DOE)n performed L25(45 ) orthogonal array , which suggested by Taguchi to reduce the high required number of experiments to 25 effected tests.  In the present study, the signal to noise (s/n) ratio have been performed for analysis the results , by statistical software(MINITAB17) to establish the  optimum condition for a process and estimate the contributions and response under optimum condition. In addition , the analysis of variance (ANOVA) has been performed to identify the significant parameters affected on accuracy and quality.

Synthesis and Spectral Analysis of Mn (II), Cu (II) ,Ni (II) and Cd (II) Complexes with Mixed Ligands containing 1,10-phenanthroline and Schiff base derived of 4-aminoantipyrine

The complexes of Schiff base of 4-aminoantipyrine and 1,10-phenanthroline with metal ions Mn (II), Cu (II), Ni (II) and Cd (II) were prepared in ethanolic solution, these complexes were characterized by Infrared , electronic spectra, molar conductance, Atomic Absorption ,microanalysis elemental and magnetic moment measurements. From these studies the tetrahedral geometry structure for the prepared complexes were suggested.The prepared ligand of 4-aminoantipyrine was characterized by using Gc-mass spectrometer

Dark Matter in the Central Region of NGC 3256

We investigated the central mass distribution of the luminous infrared galaxy NGC 3256 at a distance of 35 Mpc by using CO(1-0) observations of the Atacama Large Millimeter and sub-millimeter Array (ALMA) and near-IR data of the Two Micron Sky Survey (2MASS). We found that there is a huge amount of invisible dynamical mass ($4.84 \times 10^{10} M_{\odot}$) in the central region of the galaxy. The invisible mass is likely caused by some dark matter, which might have a cuspy dark matter profile. We note that this dark matter is difficult to explain with the conventional Modified Newtonian Dynamics (MOND) model, which is only applicable at a low acceleration regime, whereas the acceleration at the central region of the galaxy is relatively strong. Therefore, this discovery might pose a challenge to the conventional MOND models.Comment: 26 pages, 7 figures, accepted by Sains Malaysian

Threshold adaptation and XOR accumulation algorithm for objects detection

Object detection, tracking and video analysis are vital and energetic tasks for intelligent video surveillance systems and computer vision applications. Object detection based on background modelling is a major technique used in dynamically objects extraction over video streams. This paper presents the threshold adaptation and XOR accumulation (TAXA) algorithm in three systematic stages throughout video sequences. First, the continuous calculation, updating and elimination of noisy background details with hybrid statistical techniques. Second, thresholds are calculated with an effective mean and gaussian for the detection of the pixels of the objects. The third is a novel step in making decisions by using XOR-accumulation to extract pixels of the objects from the thresholds accurately. Each stage was presented with practical representations and theoretical explanations. On high resolution video which has difficult scenes and lighting conditions, the proposed algorithm was used and tested. As a result, with a precision average of 0.90% memory uses of 6.56% and the use of CPU 20% as well as time performance, the result excellent overall superior to all the major used foreground object extraction algorithms. As a conclusion, in comparison to other popular OpenCV methods the proposed TAXA algorithm has excellent detection ability

Assessment of Interleukin-10 Levels in Iraqi Diabetic Type 2 Patients Infected with Toxoplasmosis

Background: Toxoplasmosis is a disease caused by an obligate intracellular protozoan parasite Toxoplasma gondii that infects birds and mammals as an intermediate host while infecting cats as a definitive host. Diabetes mellitus is a global metabolic disorder that appeared due to inappropriate hyperglycemia. Interleukin-10 is an immunoregulatory cytokine that plays a main role in modulating inflammation, it’s considered  as main inhibitory cytokine against the action of inflammatory cytokines such as IL-12. The main aim of this study is to assess the levels of IL-10 in Iraqi diabetic type 2 infected with toxoplasmosis.Methods: This study concluded 109 cases of Iraqi diabetic type 2 patients and 80 samples of healthy individuals collected from private lab in Baghdad, Iraq, during period from March to June 2022 with age mean 49.9 ± 1.29.Results: The results showed that the group of diabetes has the highest level of glucose in diabetes diagnostic tests 7.9 ± 0.178 HbA1C, 174.55 ± 3.96 mg/dl FBS and 216.89 ± 4.96 mg/dl RBS respectively. Moreover, 51/109 samples of diabetic patients have highest level of IgG anti-Toxoplasma 34.95 ± 7.5 UI/mL in CMIA followed by 30/80 samples of healthy individuals have seropositive for the same antibody 32.7 ± 8.45 UI/mL in the same assay with significant differences While, all samples were seronegative for IgM anti-Toxoplasma. The group of healthy control has the highest levels of IL-10 in ELISA 320.43 ± 17.64 pg/ml followed by the group of diabetic patients 138.38 ± 5.69 pg/ml. Also, the concentration of this interleukin was in the group of toxoplasmosis patients which considered as a control positive 115.45 ± 4.44 pg/ml. While, the group of diabetic patients with toxoplasmosis has the lowest concentration of the interleukin 102.3 ± 7.05 pg/ml with highly significant differences.Conclusion: The conclusion of this study is the IL-10 has been shown highest levels in healthy control in comparison with other study groups
