ABSTRACT: The energy sources such as oil and gas are transported through underground pipelines. This is the most economical and safest mode of transportation. Leakage is one of the main causes of heavy product losses. It disturbs the normal operation of the pipeline, pollutes the environment, and threatens personal safety. Corrosion of pipelines transporting oil and gas resources leads to product leakage and affects the economy. Other significant causes for pipeline leaks are damage by excavation equipment, accidents, theft, earth movement, etc.......

Keywords: pipeline, radiotracer, data logger, sample analysis.

ABSTRACT: The present study investigated the potentials of green inhibitors (leaf extracts of Heinsia crinita (atama) and Editan (Clasianthera Africana)) for the prevention of corrosion of mild steel in an acidic media. The experiment was tested in a control environment and in an acidic environment under different concentrations of the green inhibitors and with fixed exposure time. The concentration of the acidic environment was fixed at 0.5 M while the concentration of the green inhibitors was varied between 0 g/mol (control) to 50 g/mol. The incremental steps were maintained.......

ABSTRACT: This study presents an in‐depth evaluation of gamma radiation shielding performance in a series of BLTC glass systems modified with varying levels of BaF₂. Key radiation interaction parameters—including the linear attenuation coefficient, mass attenuation coefficient, half‐value layer, mean free path, effective atomic number, effective electron density, and buildup factors—were systematically analyzed over a broad range of photon energies. The experimental results reveal that the attenuation properties follow an exponential decay, in agreement with the Beer–......
