Published: April 2023

The variation of the bulk etch rate (VB) of nuclear track detector CR-39 with the normality of the chemical etchant were studied. The removal thickness measurement method is used to determine the bulk etch rate. the detectors were etched by an aqueous solution of NaOH with normalities (4, 5, 6, 7) N at temperature (70±1) oC. It was found that the bulk etch rate is exponentially increasing with the normality of the solution and its values are (0.687, 1.421, 0.954, 2.082) µm/h at normalities (4, 5, 6, 7) N respectively. the relation between the bulk etch rate and the etchant normality was an exponential relation and the results showed good agreement with the results of the others used other normalities and another measurement method.

The efficiency of Color Models layers at Color Images as Cover in text hiding
Authors: Qasim Mohammed Hussein  , Ahmed Saadi Abdullah  , Nada Qasim Mohammed  
Published: April 2023

The color images are used widely as a cover in hiding of the information. Since the variety of applications of the color image there are several color models of color image. Most color models consist of three layers. The nature of the color mode of the cover plays a main role in determining the robustness and security of hiding algorithm.
The objective of this paper tests the layers, components, of the color models of cover color images, to figure out which color layer of each color model is best (less affected) to use as a cover to hide information within each color model in the hiding process. The experiments concentrate on the hiding texts in two positions of each layer, 7th bits and 8th bits (LSB). Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR) were used to measure the affected of hidden text in layers. The tests were done on nine colors models: RGB, HSV, HIS, HSL, HSB, YCbCr, La*b*, LUV and CMYK.
The results show that some of color models have best layer to hide text such as YCbCr, HSI, CMYK, HSL and LUV . In other color models which have been tested, there is not a distinctive layer. The layer H is the worst because any hiding leaves a clear impact on the cover image.

The powder of Mn-Zn ferrite having the chemical formula Mn(1-x)ZnxFe2O4 where x varies from 0, 0.1, 0.2, 0.3, 0.4, and 0.5 were synthesized by solid state Reaction method. The X-Ray Diffraction studies confirm the formation of spinel cubic structure. The particle size was calculated by X-ray broadening studies. Also the structural parameters like Lattice Constant, X-ray density, bulk density (d), Porosity (P), ionic radius (Ra , Rb) and anion parameter or the oxygen positional parameter for all the samples. The micro structural features of the samples were obtained using a Scanning Electron Microscopy (SEM). The magnetic properties of Mn(1-x)ZnxFe2O4 ferrites were strongly affected by the Zn content. The saturation magnetization increased. It may be due to relatively high orbital contribution of Mn2+ ions to magnetic moment, which gives large induced anisotropy.
