Water abstraction

Water abstraction, or water extraction, is the process of taking water from any source, either temporarily or permanently. Most water is used for irrigation or treatment to produce drinking water.
Depending on the environmental legislation in the relevant country, controls may be located on abstraction to limit the amount of water that can be removed. Over abstraction can lead to rivers drying up or the level of groundwater aquifers reducing unacceptably.
The science of hydrogeology is used to assess safe abstraction levels.

Nutrients in food

Between the extremes of optimal health and death from starvation or malnutrition, there is an array of disease states that can be caused or alleviated by changes in diet. Deficiencies, excesses and imbalances in diet can produce negative impacts on health, which may lead to diseases such as scurvy, obesity or osteoporosis, as well as psychological and behavioral problems. The science of nutrition attempts to understand how and why specific dietary aspects influence health.

Nutrients in food are grouped into several categories. Macronutrients means fat, protein, and carbohydrates. Micronutrients are the minerals and vitamins. Additionally food contains water and dietary fiber.

Arrestors

A lightning arrestor is a mechanism that shunts or diverts the huge voltage and electrical current of a lightning hit to an earthed ground. Electrical equipment can be protected from lightning by an arrester, a device that contains one or more gas-filled spark gaps between the equipment's cables and earth. An arrester is designed to handle much higher jolts of electricity than a surge protector, which cannot handle a direct strike at all.
When lightning exceeds the arrestor's breakdown voltage, the currents arcs to the ground and prevents arcing around inside sensitive electronic equipment joined further down line. The glimmer gap may be filled with a noble gas, or with air. Other types may work by overcrowding normal irregular current, but allowing the direct current from a lightning discharge.
Lightning arrestors are normally installed on electric power broadcast lines, and on radio tower feed lines between the radio antenna and spreader. Smaller ones can also be installed on the mains electricity service coming into a building, just before the circuit breaker panel. Telephone wires also have fusible links sometimes where they enter a building, joined by carbon which will vaporize with very high current.

History of Mainframe computer

More than a few manufacturers formed mainframe computers from the late 1950s through the 1970s. In those "glory days" it was "IBM and the Seven Dwarfs": Burroughs, Control Data Corporation, General Electric, Honeywell, NCR, RCA, and UNIVAC. IBM's dominance grew out of their development of the 360 series mainframes; this basic architecture has sustained to develop into their current zSeries/z9 mainframes which are debatably the only mainframe architecture still extant that dates from this early period. That said; while they can still run 24-bit System/360 code, the 64-bit series and System z9 CMOS servers have almost nothing physically in common with the older systems. The larger of the latter IBM competitors were also often referred to as "The BUNCH" from their initials.

Rhizome

In botany, a rhizome is a classically underground, horizontal stem of a plant that often sends out roots and shoots from its nodes. Though a number species of plants have above ground rhizomes or rhizomes that sit at the soil surface with some Iris species. Rhizomes may also be referred to as creeping rootstalks, or rootstocks. A stolon is like to a rhizome, sprouting from an existing stem with long internodes and generating new shoots at the end. Rhizomes have short internodes noramly with papery leaves at the nodes, they root at the underside and form green shoots at the apex.
Many plants have rhizomes that serve to spread the plant by vegetative reproduction. Examples of plants that do this are asparagus, ginger, irises, Lily of the Valley, Cannas and sympodial orchids. The spreading stems of ferns are also called rhizomes.
A tuber is a thickened part of a stolon or root that has been enlarged for use as a storage organ.They are classically high in starch. An example of a tuber is the common potatoa modified stolon. Thought the term tuber is frequently used impresicly and some times applied to plants with rhizomes.

Puppy

A puppy is a juvenile dog, usually less than one year of age. The term is sometimes abbreviated to pup, a term which is also used for the offspring of wolves.
Puppies are very playful and active. A lethargic or listless puppy is unusual, and often times a precursor to illness.

Types
Some breeds traditionally have their tails docked or ears cropped, or both. Many countries now ban cropping and docking for cosmetic purposes, but other countries have no such prohibitions. Some breeders favor to remove a dog's dewclaws to prevent future injuries. These procedures are usually performed within the first few days after birth, by a veterinarian, or by an experienced breeder.
Size varies among breeds, some puppies are 1-3lbs, while others are 15-20lbs. Coats can change color as the puppy grows older, this is commonly seen in breeds such as the Yorkshire Terrier.

Asian Paradise Flycatcher

The Asian Paradise Flycatcher, also known as the Common Paradise Flycatcher, is a medium-sized passerine bird. It was before classified with the Old World flycatcher family Muscicapidae, but the paradise flycatchers, monarch flycatchers and Australasian fantails are now usually grouped with the drongos in the family Dicruridae, which has most of its members in Australasia and steamy southern Asia.

The Asian Paradise Flycatcher breeds from Turkistan to Manchuria. It is migratory, wintering in steamy Asia. There are occupant populations further south, for example in southern India and Sri Lanka, so both visiting migrants and the locally breeding subspecies occur in these areas in winter.
This species is usually found in thick forests and other well-wooded habitats. Three or four eggs are laid in a cup nest in a tree.
The adult male Asian Paradise Flycatcher is about 20 cm long, but the long tail bunting double this. It has a black crested head, chestnut upperparts and pale grey underpants.
By their second year, the males of the migratory Indian race T. p. paradise begin to obtain white feathers. By the third year, the male plumage is completely white, other than the black head. Males of the sedentary Sri Lankan race T. p. Ceylonese’s are always chestnut.
The female of all races resembles the old joke male, but has a grey throat, smaller crest and lacks the tail streamers.
