Research ArticleOpen accessEvery word in the titleEffect of γ- ray, Microwave Heating and Solar Irradiation of Apple Juice on Organochlorinated Pesticides ResiduesK. Al-Ismail, S. Herzallah, H. DmoorThis study was conducted to evaluate the effect of solar radiation, microwave heating and γ-irradiation on the Organochlorinated Pesticide (OCP’s) in apple juice. The solar radiation caused a destruction of 20% after 20 hr exposure to sunlight compared to 12% reduction for the tested OCP’s after microwave heating for 10 min. On the other hand, the use of γ-irradiation leads … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,165 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleClassification of X-Ray Images Using Convolutional Neural Network and Automatic Hyper-Parameter Selection to Detect Tuberculosis (TB)Biswaranjan Debata, Rojalina Priyadarshini, Sudhir Kumar Mohapatra, Tarikwa Tesfa BedaneTuberculosis (TB) is a major public health issue in India, contributing significantly to the global burden of respiratory diseases. This study introduces a Convolutional Neural Network (CNN)--based model for the early and cost-effective detection of TB using chest X-ray images. The proposed model, featuring 13 layers and automated hyperparameter selection, classifies images as infected or not infected. It is evaluated … …Journal of Computer Science, Vol. 21, Issue 2 · 21 Jan 2025 · 6,998 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleClassification of Thoracic X-Ray Images of COVID-19 Patients Using the Convolutional Neutral Network (CNN) MethodRamacos Fardela, Dian Milvita, Mawanda Almuhayar et al.Recently, radiology modalities have been widely used to detect COVID-19. Thoracic X-rays and CT scans are the primary radiological tools utilized in the diagnosis and treatment of individuals with COVID-19. In addition, chest CT scans are more accurate and sensitive in early COVID-19 identification. A new problem arises in diagnosing the results of CT scan images of COVID-19 by radiologists … …Journal of Computer Science, Vol. 20, Issue 4 · 1 Feb 2024 · 5,761 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLT-LBP-Based Spatial Texture Feature Extraction with Deep Learning for X-Ray ImagesPankaja Lakshmi P., Sivagami M.The novel logarithmic transformation of Local Binary Pattern (LT-LBP) for texture feature extraction is used with Deep Learning (DL) models. The Computational complexity in the DL models asymptotically increases with the data sesssst and the depth of the layers in Convolutional Neural Networks (CNN). Pre-processing the images before training the DL model holds a strong impact on the operation speed … …Journal of Computer Science, Vol. 20, Issue 1 · 18 Dec 2023 · 7,195 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBone Microarchitecture by Dentistry Digital X-Ray (BµA-DDX) Software: A Pilot Study of the Analysis of Bone Density using Digital Dental X-RaysAdriane Yaeko Togashi, Adair Santa Catarina, Lucas Renato Piana Batistussi, Guilherme CoelhoThe Bone Microarchitecture by Dentistry Digital X-Ray (BµA-DDX) software was designed to determine jaw bone quality using digital dental X-rays. In order to identify patients with a suspicion of low bone density, a system was developed to evaluate bone microarchitecture through the analysis of samples collected in digital panoramic X-rays. The samples were collectedat two sites of the mandible: alveolar … …Current Research in Dentistry, Vol. 6, Issue 2 · 23 Feb 2016 · 7,474 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimization of Energy Dispersive X-Ray Fluorescence Spectrometer to Analyze Heavy Metals in Moss SamplesMohd Zahari Abdullah, Ahmad Saat, Zaini HamzahProblem statement: Mosses had been widely used as bioindicator especially to study the levels of trace metals pollutants in the surrounding ambient air because of their high efficiency to accumulate heavy metals contamination. There had been increasing demand to get a suitable analytical tools to determine the chemical contents of moss samples in this type of media. This study was … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 18 Aug 2011 · 7,793 accessesView PDFCite
EditorialOpen accessEvery word in the titleProblems of Ultra-High Energy Cosmic RaysAnna V. UrysonCosmic rays are energetic particles coming to the Earth from space. They bombard the atmosphere producing cascades of particles that spread over a large area when they reach the ground. Cosmic ray energies vary in the wide band from about 108 eV up to few 1020 eV. It is established that most particles with energies of ~ (108-109) eV come … …Space Science International, Vol. 2, Issue 1 · 6 Dec 2014 · 13,865 accessesView PDFCite

Approach: The dosimeters are composed of Poly Vinyl Alcohol (PVA), Trichloroacetic Acid (TCA) at … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 8,091 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSEQUENTIAL ESTIMATION OF THE SQUARE OF THE RAYLEIGH PARAMETERMohamed TahirThe problem addressed is that of sequentially estimating the square of the parameter of the Rayleigh distribution, subject to a weighted squared loss plus cost of sampling. We propose a sequential procedure and provide a second-order asymptotic expansion for the incurred regret. It is seen that the asymptotic regret is negative for a range of values of the parameter. …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 19 Jun 2014 · 6,443 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTHE ELECTRICAL PROPERTIES OF Mg-Cu-Zn FERRITES IRRADIATED BY γ-RAYS OF 60Co SOURCEMohamed Eltabey, H. Ebrahim Hassan, Ismail Abd Elrahim AliFerrite samples with chemical formula MgxCu0.5-xZn0.5Fe2O4 (x = 0.0, 0.2 and 0.4) was prepared by the conventional ceramic method.
