Ag thin films with (84,89,94,269,290) nm, thickness were prepared at different deposition times (10,30,60) sec. The crystalline structure of thin films was evaluated by X-ray diffraction (XRD) and the atomic force microscopy (AFM) were employed for surface morphological studies of the films. The results show that the thickness of the films increases with increases magnetic field to 250 Gauss, and when are greater than (250Gauss) the effect of magnetic field starts to decrease and be ineffective, and also the results indicate an increase of the grain size from (144.9 -276.7) nm and films surface roughness from (0.431-22.7) nm.

In this paper, a new pseudo-coloring method proposed for colorizing the frontal chest x-ray medical images which are very important for disease detection and recognition. The key idea of this method is applying different and various experimental mathematical equations on the proposed medical sample image, which it belongs to the patient with Hydatid cyst parasite disease in the lung. The counterfeit coloring had intense contribute in enhancing of the visual attractiveness of medical images, the output colored images have a better visual description, it has a possibility to describe hidden information better than a conventional monochromatic image, this is an excellent indicator of the algorithm's suitability for the purpose for which it was formulated.","PeriodicalId":16215,"journal":{"name":"Journal of Kufa - Physics","volume":"52 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90836358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nitrogen plasma produced by dc glow discharge is the investigated with a manypurpose of studying plasma phenomena, the discharge system consists of two electrodes, the cathode forms various geometrical shapes and anode as a disc- shaped with diameter (8.8cm). The electrodes are enclosed in a large cylindrical glass chamber of pyrex filled with nitrogen gas. Two important physical parameters affecting the condition of the discharge are the gas pressure and constant inter-electrode distance. The discharge current-voltage (I-V) characteristic curves of the discharge were measured at variable pressure and the inter-electrode spacing, Current-voltage characteristics visualization of the discharge indicate that the discharge is take place in the normal glow region. The (I-V) characteristics of nitrogen gas discharge were deduced as a plasma system operated in normal glow discharge nitrogen, which is very important parameter in the sputtering and deposition. Also, the discharge current is increased for nitrogen plasma discharge with the increasing of the working pressure lead to increase the deposition rate.
