Deconvolution and Growth curve for Thermoluminescence glow curves Radiat. Phys. Chem. (IF 2.8) Pub Date : 2024-07-01 René Rojas Rocca
In this work, a new program is presented that, in addition to performing the deconvolution of Thermoluminescence glow curves, allows the user to store multiple deconvolution data. This data is stored in an internal database, which allows the fitted parameters to be compared. After these deconvolutions, the program allows the user to summarize the values of the selected parameters. These values can

Calcium carbonate scale thickness prediction in annular three-phase flow using gamma-ray densitometry and artificial neural networks Radiat. Phys. Chem. (IF 2.8) Pub Date : 2024-07-01 A.C.L. Carvalho, W.L. Salgado, R.S.de F. Dam, C.C. Conti, C.M. Salgado
This study presents a methodology based on gamma-ray densitometry for predicting calcium carbonate (CaCO) scale thickness in pipelines of three-phase systems (oil, salty water, and gas) in the petroleum industry. Both concentric and eccentric scale thicknesses were calculated using analytical equations and artificial neural networks. The artificial neural networks were trained using a backpropagation

Impact of natural aggregates and some industrial wastes on radiation shielding properties of heavyweight concrete: Experimental and theoretical study Radiat. Phys. Chem. (IF 2.8) Pub Date : 2024-07-01 Muhammad S. Mansy, Eman Anwar EL-Shamy, Khaled Fawzi Khalil, Mohammed Essam Elawady, Helal Abd El-Kader, Khaled Adly Malek
The methodology to produce five concrete specimens with high density has been conducted, incorporating natural aggregates such as sand and basalt as well as commercial aggregates like lead and copper. These specimens have been designed for use in structural and radiological shielding purposes. The five specimens exhibit exceptional mechanical features, characterized by superior performance and remarkable

Effect of gamma ray irradiation and packaging on the storage quality of kodo millet (Paspalum scrobiculatum L.) flour Radiat. Phys. Chem. (IF 2.8) Pub Date : 2024-07-01 D. Shobha, Ashok Badigannavar
Kodo millet is one of the small millet species, grown widely in the tropical/subtropical regions. In order to prevent the problem of post-harvest losses, various preservation techniques have been used such as irradiation and suitable packaging material. In the present study, shelf life of kodo millet flour was investigated using gamma rays at 1.5 kilogray (kGy) (irradiation, IR) and different packaging
