Rain Sensors

Rain sensors for irrigation systems are obtainable in both wireless and hard-wired versions, most employing hygroscopic disks that bulge in the presence of rain and shrink back down again as they dry out - an electrical switch is in turn depressed or released by the hygroscopic disk stack. However, some electrical type sensors are also marketed that use tipping bucket or conductance type probes to measure rainfall. Wireless and wired versions both use alike mechanisms to momentarily suspend watering by the irrigation controller - purposely they are connected to the irrigation controller's sensor terminals, or are installed in series with the solenoid valve common circuit such that they stop the opening of any valves when rain has been sensed.Some irrigation rain sensors also contain a freeze sensor to keep the system from operating in freezing temperatures Some US states, such as Florida, New Jersey, Minnesota, and Connecticut mandate the use of a rain sensor in all new lawn sprinkler systems.

Forest

A forest is an area with a high bulk of trees. There are several definitions of a forest, based on a variety of criteria. These plant communities face large areas of the globe and function as animal habitats, and soil conservers, constituting one of the most important aspects of the Earth's biosphere. While frequently thought of as carbon dioxide sinks, grown-up forests are approximately carbon neutral with only troubled and young forests acting as carbon sinks. However mature forests do play a main role in the global carbon cycle as stable carbon pools, and authorization of forests leads to an increase of impressive carbon dioxide levels.

Forests sometimes have many tree species within a small area or comparatively few species over large areas. Forests are frequently home to many animal and plant species, and biomass per unit area is high compared to other plants communities. Much of this biomass occurs below-ground in the origin systems and as partly decomposed plant accumulation. The woody element of a forest contains lignin, which is comparatively slow to decompose compared with other organic materials such as cellulose or carbohydrate.

Music

Music is an art structure that involves organized sounds and silence. It is expressed in terms of and the value of sound

Music may also involve generative forms in time through the creation of patterns and combinations of normal stimulus sound. Music may be used for artistic, expansive, entertainment, traditional purposes.

In the Romantic period, music became more expressive and touching, increasing to encompass literature, and philosophy. Later Romantic composers created multifaceted and frequently much longer musical works.

Chinese White Dolphin

The Chinese White Dolphin also called Indo-Pacific Humpback Dolphin, is a species of the Humpback dolphin and is one of eighty cetacean species. The adult dolphin is generally white or grey in colour. The population along the Chinese coast is unique in that they display a pink-coloured skin. This colour of the skin is not an effect of colour pigmentation, but is actually from blood vessels used for thermoregulation to avoid overheating during exertion. The adult's body length is about 220 - 250 centimeters and the infant's body length is about 1 meter. The normal weight of an adult is around 150 to 230 kilograms.

The Indo-Pacific dolphins can be found throughout Southeast Asia, and they breed from South Africa to Australia. There are two types, with Sumatra, one of the Indonesian islands, as the dividing line between the Chinese and the Western subspecies, Sousa chinensis plumbea. The two subspecies vary in color and size of their dorsal fin. The subspecies found in Southeast Asia has pinkish white skin and a bigger dorsal fin but lacks the fatty hump of its South African and Australian counterparts.

Weedy Sea Dragon

The Weedy Sea Dragon or Common Sea Dragon is a marine fish related to the seahorse. It is the only member of the genus Phyllopteryx. They occur in water 3 to 50 meters deep round the southern coastline of Australia, approximately between Port Stephens, New South Wales and Geraldton, Western Australia, as well as around Tasmania. Weedy sea dragons are named for the weed-like projections on their bodies that camouflage them as they move among the seaweed beds where they are usually found.

Weedy sea dragons reach up to 45 cm in length. They feed on tiny crustacea and other zooplankton, which are sucked into the end of their tube-like snout.A more cryptic relative of the weedy sea dragon is the leafy sea dragon. However, according to the November 2006 issue of National Geographic magazine, marine biologist Greg Rouse believes leafy and weedy sea dragons may be the same species residing in a wide territory.

The Aquarium of the Pacific in Long Beach, California and Melbourne Aquarium in Australia are the only facilities in the world to have successfully bred Weedy Sea Dragons in captivity.The Weedy Sea Dragon is an aquatic emblem of the State of Victoria.The Leafy Sea Dragon Festival is held biennially in the Fleurieu Peninsula, south of Adelaide.
