CAMERAS / CAMERA TESTING |
|
A camera is a device used to take pictures (usually photographs), either singly or in sequence, with or without sound recording, such as with video cameras. A camera that takes pictures singly is sometimes called a photo camera to distinguish it from a video camera. The name is derived from camera obscura, Latin for "dark chamber", an early mechanism for projecting images in which an entire room functioned much as the internal workings of a modern photographic camera, except there was no way at this time to record the image short of manually tracing it. Cameras may work with the visual spectrum or other portions of the electromagnetic spectrum.

DEMOLITION |
|
Demolition is the opposite of construction: the tearing-down of buildings and other structures. It is contrasted with deconstruction, which is the taking down of buildings while carefully preserving valuable elements for re-use.
|
DREDGING / RECLAMATION |
|
Dredging is miscellaneous excavator-type work underwater, usually in shallow sea or fresh water.
A dredge is a device for scraping or sucking the seabed, used for dredging.
A dredger is a ship or boat equipped with a dredge.
American usage sometimes calls the ship or boat a dredge.

DROWNING |
|
Drowning is death caused by the filling of the lungs by a liquid, usually water, rendering breathing ineffective and leading to death due to asphyxia. Near drowning is initial survival of a drowning event, and can lead to serious secondary complications including death later on; cases of near drowning therefore also require attention by medical professionals. Secondary drowning is death due to chemical and biological changes in the lungs after a near drowning incident or exposure to chemicals. In many countries, drowning is one of the leading causes of death for children under 14 years old.

LEAD |
|
Lead is a chemical element in the periodic table that has the symbol Pb (L. plumbum) and atomic number 82. A soft, heavy, toxic and malleable poor metal, lead is bluish white when freshly cut but tarnishes to dull gray when exposed to air. Lead is used in building construction, lead-acid batteries, bullets and shot, and is part of solder, pewter, and fusible alloys. Lead has the highest atomic number of all stable elements. (But see the article on Bismuth, which has a half life so long it can be considered stable.)

PHOTOGRAPHY |
|
Photography is the process of making pictures by means of the action of light. It involves recording light patterns, as reflected from objects, onto a sensitive medium through a timed exposure. The process is done through mechanical, chemical or digital devices commonly known as cameras.
The word comes from the Greek words φως phos ("light"), and γραφις graphis ("stylus", "paintbrush") or γραφη graphê, together meaning "drawing with light" or "representation by means of lines" or "drawing." Traditionally, the product of photography has been called a photograph. The term photo is a convenient abbreviation. Many people also call them pictures. In digital photography, the term image has begun to replace photograph. This term is neither more nor less correct than photograph, either in film or digital photography. (The term image is traditional in geometric optics.)

Scuba diving is swimming underwater while using self-contained breathing equipment.
Scuba divers exploring fish and coral.By carrying a source of compressed air, the scuba diver is able to stay underwater longer than with the simple breath-holding techniques used in Snorkeling and Free-diving, and is not hindered by air-lines to a remote air source. The scuba diver typically swims underwater by using fins attached to the feet. However, some divers also move around with the assistance of a DPV (Diver Propulsion Vehicle), commonly referred to as a "scooter", or by using surface-tethered devices called sleds, which are pulled by a boat.
The term SCUBA arose during World War II and originally referred to USA combat frogmen's oxygen rebreathers, developed by Dr. Christian Lambertsen for underwater warfare. Today, SCUBA typically usually refers to the in-line open-circuit equipment, developed by Emile Gagnan and Jacques-Yves Cousteau, in which compressed gas (usually air) is inhaled from a tank and then exhaled into the water. However, rebreathers (both semi-closed circuit and closed circuit) are also self-contained systems (as opposed to surface-supplied systems) and are therefore classified as SCUBA.
Although the word 'SCUBA' is an acronym for "Self Contained Underwater Breathing Apparatus", it has also become acceptable to refer to SCUBA as 'scuba equipment' or 'scuba apparatus'.

RIVER DREDGING |
|
In American usage any floating vessel equiped with dredging equipment is called a dredge. Used to maintain river naviagability.
|
SCUBA |
|
SCUBA is an acronym for Self-Contained Underwater Breathing Apparatus. These initials originated in 1939 in the US Navy to refer to US military diver's rebreather sets. As with radar, the acronym has become so familiar that it is often not capitalised and is treated as an ordinary word: for example, it has been taken into the Welsh language as "sgwba". A scuba set provides a scuba diver with the breathing gas necessary to breathe underwater.

SEAGRASS - MEADOWS |
|
Seagrass (or sea-grass in British English) are flowering plants from four plant families (Posidoniaceae, Zosteraceae, Hydrocharitaceae and Cymodoceaceae) that grow in the marine saline environment.
They are called seagrasses only because most species superficially resemble terrestrial grasses of the Family Poaceae. Because these plants must photosynthesize, they are limited to growing submerged in the photic zone, and most occur in shallow and sheltered coastal waters anchored in sand or mud bottoms. They undergo pollination while submerged and complete their entire life cycle underwater. There are about 60 species worldwide (although the taxonomy is still disputed).

TELECOMMUNICATIONS |
|
Telecommunications is the communication of information over a distance. The term is most used to refer to communication using some type of signalling, such as the aldis lamp or the transmission and reception of electromagnetic energy. This covers many media and technologies including radio, fiber optics, telegraphy, television, telephone, data communication and computer networking, although other types of signalling are also included (see Telecommunications History and especially Early Telecommunications).
