Electrospun non-woven poly(ε-caprolactone) (PCL) microfiber meshes are described as biodegradable, mechanically robust, and reusable polymeric oil sorbents capable of selectively retrieving oil from simulated oil spills in both fresh and seawater scenarios. Hydrophobic PCL meshes have >99.5% (oil over water) oil selectivity and oil absorption capacities of ~10 grams of oil per gram of sorbent m...

The increasing complexity of construction, along with its rapid development, as well as ambiguities and gaps in the legal terms governing constructions, lack of trust in the parties regarding obligations and regulations are the main reasons of disagreements in domestic projects. These disagreements are inevitable even in contracts which are set correctly. Disagreements are costly, time-consumin...

Regarding the contingency theory, the purpose of this research is to identify factors affecting the development of accounting and financial management procedures for joint operating agreements in Iran's oil and gas industry. To this end, at first, some partial factors were identified through deep study of theoretical foundations. Subsequently, in order to identify environmental factors, a semi-...

For almost a century, various predictions have been made that the human race was imminently going to run out of available petroleum. The passing of time has proven all those predictions to have been utterly wrong. It is pointed out here how all such predictions have depended fundamentally upon an archaic hypothesis from the 18th century that petroleum somehow (miraculously) evolved from biologi...

We study a two-sided market in which a platform mediates between sellers and buyers, and signs private contracts with sellers. We compare this market with (i) a one-sided market with public contracts, and (ii) a two-sided market with public contracts. We find that equilibrium royalties can be positive or negative in a one-sided market with public contracts, are negative in a twosided market wit...
