Published: April 2023

Beta particle has a huge applications in industry, medicine and research fields. The aim of the present study is to calculate the mass attenuation coefficients (μ / ρ)β_ and the range of Rβ- for negative beta particles within the energy range (0.257-2.25) MeV for 13Al and 79Au respectively. Use the equation of Kisse and Vertes to calculate the mass attenuation coefficient and the Tabata equations to calculate the range of electrons in the same elements. All the equations were adopting by the program (Visual studio professional 2012). The results we obtained were compared with the available experimental one, indicating that they are in good agreement, thus supporting the possibility of applying them to other elements effectively. As for the range it is a function of the negative beta particle energy and then the range in the aluminum is greater than the of the values in gold due to the electronic density of the gold element.

Published: April 2023

Measurements of gamma –rays attenuation in lead and iron sheets were carried out using direct spectrum and gamma- gamma fast slow coincidence spectrometer composed of two 3"×3"NaI(Tl) detectors and Na-22 source. Measurements of mass attenuation coefficient at 511keV were carried out and its values (in cm²/g units) for lead from direct spectrum for the cases of without and with using a collimator (1cm diameter and 5 cm length) were 0.12029 and 0.13591and from coincidence spectrum were 0.10721 and 0.10602 respectively. For iron sheets the mass attenuation coefficient values from direct spectrum for the cases of without and with using a collimator were 0.0780 and 0.0766 andfrom coincidence spectrum were 0.0593 and 0.0616 respectively. The present results registered by direct measurement are little lower than the standard values due to making only photoelectric absorption needed for comparison with coincidence results where the latter showed lower values.
The build-up factor were also measured as function of thickness using lead and iron sheets and found fluctuating around unity for lead and iron coincidence spectra and iron direct spectrum, whereas its increases gradually for lead direct spectrum for the measured thickness range. The coincidence spectrometer greatly reduces scatteringevents in the measured material, and thus its results somewhat resemble that of direct measurements with using the collimator.
Study the noise effect on the edges and cross correlation of TV images
Authors: Abdullah .H. Muhammad  , Layla Mahdi Salih  
Published: April 2023

The noise that associated with TV images is considered to be a very important problem that complicates the developments of these systems. Because of that, it makes the interpretation and analysis of informative images a very difficult process, and lessens their advantages. The most common type of these images are TV images transmitted by antenna work with (VHF, UHF) frequency and Satellite Transmission. Because TV images move through a complicated system in generating the TV or video signal, coding them, transmitting them, and receiving them by decoding and passing with different sets until appearing on screen. This will lead to a loose and fraud for a part of the information sent in the wave. As a result, it will be affected by an additive noise (Gaussian noise) which leads to deforming and destroying the quality of these images.
This research aimed at studying the effect of the noise influence of this noise on edge as well as study of the relation between the statistical operators that include the mean and standard deviation (µ, σ) of edge’s regions for the components RGB and illumination component L as a function of time and as a function of antenna rotation.
As well as we studied the relation between (µ, σ) and signal to noise ratio SNR for the cross correlation of edge's regions and for a homogeneous regions as well as for image as a whole once as a function of time and the other as a function of the angle of antenna rotation as in the first.

Published: April 2023

There are 30 of bacterial samples were isolated from 45 samples of different infections. These isolates were diagnosed microscopically and by using biochemical tests. ability of their resistance was tested against the following antibiotics: (amoxicillin, tetracycline, cephalexin, nitrofurantoin, ciprofloxacin, clarithromycin, erythromycin, ampicillin, rifampin), and for detection the sites of genes encoding for antibiotic resistance , bacterial conjugation experiments was done for some of bacterial isolates that contain plasmids. Results of bacterial conjugation has revealed that antibiotic resistance genes in isolates (P. aeruginosa (14), E.coli (4)) were present on DNA plasmid , not on chromosome. But the other isolates, we could not find conjugated bacterial colonies for them which indicate that there DNA plasmids do not have auto transmission.
