Petroleum exploration is an economical activity where many billions of dollars are invested every year. Despite these enormous investments, it is still considered a classical example of decision making under uncertainty. In this paper, a new hybrid fuzzy-probabilistic methodology is proposed and the implementation of a software tool for assessing the risk of petroleum prospects is described. Th...

Nearly 95% of monomers or chemical intermediates used today are based on fossilized carbon such as coal and petroleum. This has resulted in a high rate of depletion of fossilized reserves, continuous escalation in petroleum prices, environmental impact with the increase in emission of greenhouse gases, and accumulation of non-biodegradable waste on earth. Current global main challenges are movi...

Purpose: The seeds of Swietenia macrophylla are used in traditional medicine for the treatment of diarrhoea.

Methods: Petroleum ether extract of the seeds of this plant, at graded doses (25, 50 & 100mg/kg body weight)...

Petroleum and petroleum-derived products can contribute to the inhibition of growth and development of plants. Soil contamination by these compounds either hampers or makes difficult the intake of water and mineral salts from the substrate, and also breaks a number of metabolic processes. As a result of the deficiency of chlorophyll and nutrients, the affected plants grow deformed roots, shoots...
