SEMIPERMEABLE MEMBRANE DEVICE (SPMD)

A long strip of low-density, polyethylene tubing filled with a thin film of purified lipid such as triolein that simulates the exposure to and passive uptake of highly lipid-soluble organic compounds by biological membranes.

SEMIVOLATILE ORGANIC COMPOUND (SVOC)

Operationally defined as a group of synthetic organic compounds that are solvent-extractable and can be determined by gas chromatography/mass spectrometry. SVOCs include phenols, phthalates, and Polycyclic aromatic hydrocarbons (PAHs).

SENSITIVITIES-BASED APPROACH (SBA)

The sensitivities-based approach is the standardised method to calculate risk capital under the Fundamental Review of the Trading Book. The new standardised approach was adopted in January 2016 by the Basel Committee on Banking Supervision as the homogeneous method for risk-weighted asset computation across all banks. The SBA is based on percentages and correlations between […]

SENSITIVITY ANALYSIS

Numerical analysis that tests how sensitive some outcome is to changes in selected variables. For example, you could test how a project’s net present value varies as you change the discount rate.

SEPTIC SYSTEM

An on-site system designed to treat and dispose of domestic sewage. A typical septic system consists of a tank that receives waste from a residence or business and a system of trenches or beds in the soil for disposal of the liquid effluent that remains after decomposition of the solids by bacteria in the tank. […]

SEPTIC TANK

An underground storage tank and treatment device for wastes from homes not connected to a sewer line. Waste goes directly from the home to the tank. The septic tank is a component of the septic system.

SEQUESTRATION

The removal of carbon dioxide from the atmosphere through biological (for example, photosynthesis in plants and trees), chemical (for example, turning CO2 into carbonate minerals), or physical processes (for example, storage of carbon dioxide in underground reservoirs).
