The Leopold matrix is the best known of the matrix methods: the activities of a project are set along one axis and the components of the environment along the other, and each cell where an activity meets a component is marked for the magnitude and the importance of the impact.

A rapid assessment is based on baseline data collected over a single season other than the monsoon, which allows the study to be completed quickly, while a comprehensive assessment collects data over all the seasons of a full year and therefore captures seasonal variation in air quality, water flow and…

The tribunal was created by the National Green Tribunal Act of 2010, its principal bench sits at New Delhi, and it hears appeals against the grant or refusal of environmental clearance as well as disputes under other environmental laws.

For a Category A project, prior environmental clearance from the central government is compulsory by the very fact of its listing in the schedule, so there is nothing for a screening stage to decide and the process begins at scoping.

The notification of 2006 makes the State Pollution Control Board, or the pollution control committee in a union territory, responsible for conducting the public hearing at or near the site of the project, for recording the proceedings and for sending that record to the appraisal committee.

Scoping is the stage at which the Expert Appraisal Committee, or the state committee for a Category B1 project, determines the Terms of Reference: the detailed list of issues, study area, seasons of data and specific concerns that the assessment must address.

Screening comes first and decides whether a Category B project needs a full assessment, making it B1, or does not, making it B2.

Under the notification of 2006, a Category A project is appraised by the Expert Appraisal Committee constituted at the centre, and the ministry grants or refuses the prior environmental clearance on that committee's recommendation.

The EIA Notification of 2006 replaced the earlier notification of 1994 and reorganised the whole clearance process, chiefly by dividing projects into Category A, appraised and cleared at the central level, and Category B, appraised and cleared at the state level, and by laying down the four stages of screening…

Section 3 of that Act gives the central government power to take all measures it thinks necessary to protect and improve the quality of the environment, and the EIA Notifications of 1994 and 2006 were both issued under it.

The National Environmental Policy Act of 1969, which came into force in 1970, required every agency of the American federal government to prepare a statement of the environmental effects of any major action it proposed, and that requirement is taken as the beginning of environmental impact assessment as a legal…

The BNC connector is the bayonet-fitting plug that is pushed on and given a quarter turn to lock, and it terminates a coaxial cable, the cable with a central copper conductor, an insulating layer, a braided metal shield and an outer jacket.

The RJ-11 is the small modular connector at the end of a telephone cord, with four or six positions and usually two or four contacts, and it was also used to join a dial-up or ADSL modem to the telephone line.

Fibre carries data as pulses of light travelling through a glass or plastic core by total internal reflection, and since no electric current flows in it, an external electromagnetic field cannot induce noise in the signal.

The correct answer is B, 480 megabits per second, the speed known as high speed in the USB 2.0 specification.

LPT stands for line print terminal, the name by which the operating system knew the parallel port, which used a twenty-five-pin DB-25 connector on the computer and a thirty-six-pin Centronics connector at the printer end.

A computer with PS/2 ports has two six-pin mini-DIN sockets that are identical in shape, so they are distinguished by colour: purple for the keyboard and green for the mouse.

Unshielded twisted pair cable has no metal foil or braid around its pairs, so it resists electromagnetic interference less well than shielded twisted pair, not better; the only protection it has is the twisting of each pair, which cancels much of the noise picked up by the two wires.

The High-Definition Multimedia Interface carries high-definition digital video and multi-channel digital audio in the same cable, which is why one HDMI lead is enough to join a computer to a television or a projector.

The Video Graphics Array connector is a D-shaped plug with fifteen pins in three rows of five, usually coloured blue, and it carries an analogue video signal only, so a separate cable is needed for sound.
