a coefficient representing the ratio of the solubility of a compound in octanol (a non-polar solvent) to its solubility in water (a polar solvent). The higher the Kow, the more non-polar the compound. Log Kow is generally used as a relative indicator of the tendency of an organic compound to adsorb to soil. Log Kow values are generally inversely related to aqueous solubility and directly proportional to molecular weight.
Organization of Petroleum Exporting Countries, oil producing and exporting countries that have organized for the purpose of negotiating with oil companies on matters of oil production, prices, and future concession rights. Current members are Algeria, Gabon, Indonesia, Iran, Iraq, Kuwait, Libya, Nigeria, Qatar, Saudi Arabia, United Arab Emirates, and Venezuela.
An individual (who may own several properties that retail gasoline products) owns and operates the building/facility/property (as opposed to a lessee dealer who does not own the property). The typical open dealer operates between 1 and 10 locations. A major or regional oil company, or a large local wholesaler supplies the facility directly. Open dealers can evolve into a distributor if they achieve a large enough volume.
A lease in which the lessee guarantees the amount of the future residual value to be realized by the lessor at the end of the term. If the equipment is sold for less than the guaranteed value, the lessee must pay the amount of any deficiency to the lessor. The lease is referred to as open-end because the lessee does not know its actual value until the equipment is sold at the end of the lease.
A lease that has the characteristics of a usage agreement and also meets certain criteria established by the FASB. Such a lease is not required to be shown on the balance sheet of the lessee.
a flow measurement device for liquids or gases that uses a restrictive orifice plate consisting of a machined hole that produces a jet effect. Typically the orifice meter consists of a thin plate with a square edged, concentric, and circular orifice. The pressure drop of the jet effect across the orifice is proportional to the flow rate. The pressure drop can be measured with a manometer or differential pressure gauge.
a chemical reaction consisting of an oxidation reaction in which a substance loses or donates electrons, and a reduction reaction in which a substance gains or accepts electrons. Redox reactions are always coupled because free electrons cannot exist in solution and electrons must be conserved.
