Published: April 2023

This research involved the preparation of Bi2-(x+y)PbxAgy Sr2Ca2Cu3O10+δ with different concentrations of (x,y) which are (x=y=0)(x=0.05,y=0.15)(x=y=0.1)(x=0.15,y=0.05) by the method of solid state reaction under hydrostatic pressure of 8 ton /cm2 and at annealing temperature of 1123K in presence of sufficient amount of oxygen.
In order to obtain an increase in the regularity of crystalline composite and also to obtain the best critical temperature, the annealing was repeated on these samples at 723K.
After X-ray diffraction (XRD) test to know how effective the partial substitution and repeated annealing is, it was obvious that the crystalline composite was of tetragonal type and the best substitution ratio is when (x=0.05,y=0.15) where the values of lattice dimensions were a=b=5.4056°A, c=37.4226°A, after repeating the annealing process on these samples ,the crystalline composite kept its type and with conspicuous increase in the length of c-axis, but the best sample after repeating the annealing was at ratio of (x=y=0.1) where the values of lattice dimensions became a=b=5.4030°A,c=37.5230°A when it was a=b=5.4011°A,c=37.0660°A before repeating the annealing .When the electrical properties of these samples was studied ,we noticed that the oxygen has an important role in increasing the critical temperature and we obtained the best critical temperature Tc=144K and that’s when x=0.05,y=0.15 while after repeating the annealing it was Tc=146K and that’s when x=y=0.1 and it was Tc=136K before repeating the annealing

Authors: Ahmed Y. Owaid  
Published: April 2023

In the present study experimental measurements have been carried out to investigate the variation of air discharge voltage (V) and current (I) as a function of working pressure (p), in the ranges (300-500 V), (2-15 mA) and (0.09-0.13 Torr) respectively. Two thick, flat and circular electrodes of radius (4 cm) of Aluminum with a Pyrex cylinder tube of length (10 cm) and radius (3.5 cm) were used to generate the air glow discharge modes. The (V-p) characteristics have shown that an increasing in the discharge voltage of normal mode and reduction in that of abnormal mode with increasing the working pressure. It also displayed that the range of upper voltage from breakdown to abnormal glow has a minimum value (15.7 V) at (0.117 Torr). In addition to that, it is found that the (I-V) characteristics of air glow discharge modes are consistent with those reported in the literature for other gases, as argon, hydrogen and oxygen. It is expected that these observations can help to reduce the voltage needed to get an intense abnormal glow discharge in the air, and to understand well the behavior of two modes of glow discharge, that is important in various applications.

Published: April 2023

This study was carried out to assess the morphological and molecular effects of the Nd: yag and Diode (semiconductor) lasers on Trichophyton rubrum Fungi using RAPD marke . Sixty samples of skin patches, nail clippings and parts of hair were collected from infected patients of both sexes (34 males and 26 females) for the age group (1-60) year of patients who have attended to Tikrit Teaching Hospital. The T.rubrum fungi was the most common among the skin fungi, T.rubrum radiated by using two lasers: the Nd: yag laser with a wavelength (530) nm and energy (300, 500, 700) mJ and for two times exposing 20 and 30 seconds by six coefficients and control sample, the low-density diode (5 mW) for 3 times 10, 20 and 30 seconds on distance 20 cm with three treatments and a control sample. DNA was extracted from the fungus after direct exposure and after leaving it to grow for a whole generation and then was used to complete RAPD reactions using five primers. The RAPD marker gave excellent results with all primers, It was noted that the exposure of T. rubrum to the Nd: yag and Diode lasers with different cards and times had different effects on DNA and caused significant changes in the RAPD patterns compared with the control group, new bands appear and others disappear. The energy affecting the fungus T.rubrum for the first laser Nd: yag is 500 mj at time 30 sec while the power of the laser Diode was 5 mw at time 20 sec. The results suggested that the diode laser is highly effective and has a great effect on the genetic material of fungi compared with the effect of the first laser. The conclusion that the use of laser can affect DNA of skin fungi and may lead to mutations which means that it can be used in the treatment of skin fungal infections and the RAPD was effective in detecting the effect of laser at the molecular level as a simple, and inexpensive.
