A complete declarative description of the computational environment is usually missing when researchers Comic Books share their materials.Without such description, software obsolescence and missing system components can jeopardize computational reproducibility in the future, even when data and computer code are available.The R package rang is a com
The petroleum industry is one of the Knee Brace most pivotal sectors of the global economy but with it comes the production of atrocious amounts of waste especially during production and refining of the oil.Oil sludge which is an example of such waste has been categorized as hazardous because it is composed of asphaltenes, heavy metals and heavy hy
