Hay's test

Hay's test, also known as Hay's sulphur flower test, is a chemical test used for detecting the presence of bile salts in urine.

Procedure

Sulphur powder is sprinkled into a test tube with three millilitres of urine and if the test is positive, the sulphur powder sinks to the bottom of the test tube. Sulphur powder sinks because bile salts reduce the surface tension of urine.

The name test is reserved by the Internet Engineering Task Force (IETF) in RFC 2606 (June 1999) as a domain name that is not intended to be installed as a top-level domain (TLD) in the global Domain Name System (DNS) of the Internet for production use.

Reserved DNS names

In 1999, the Internet Engineering Task Force reserved the DNS labels example, invalid, localhost, and test so that they may not be installed into the root zone of the Domain Name System.

The reason for reservation of these top-level domain names is to reduce the likelihood of conflict and confusion. This allows the use of these names for either documentation purposes or in local testing scenarios.

Types

As of 2015, IANA distinguishes the following groups of top-level domains:

List of Internet top-level domains

This list of Internet top-level domain extensions contains all top-level domains, which are those domains in the DNS root zone of the Domain Name System of the Internet.

The official list of all top-level domains is maintained by the Internet Assigned Numbers Authority (IANA). IANA also oversees the approval process for new proposed top-level domains. As of January 2016, the root domain contains 1205 top-level domains, while a few have been retired and are no longer functional.

Types

As of 2015, IANA distinguishes the following groups of top-level domains:

Original top-level domains

Seven generic top-level domains were created early in the development of the Internet, and pre-date the creation of ICANN in 1998.

Hay

Hay is grass, legumes, or other herbaceous plants that have been cut, dried, and stored for use as animal fodder, particularly for grazing animals such as cattle, horses, goats, and sheep. Hay is also fed to smaller animals such as rabbits and guinea pigs. Pigs may be fed hay, but they do not digest it as efficiently as more fully herbivorous animals.

Hay can be used as animal fodder when or where there is not enough pasture or rangeland on which to graze an animal, when grazing is unavailable due to weather (such as during the winter) or when lush pasture by itself is too rich for the health of the animal. It is also fed during times when an animal is unable to access pasture, such as when animals are kept in a stable or barn.

Composition

Commonly used plants for hay include mixtures of grasses such as ryegrass (Lolium species), timothy, brome, fescue, Bermuda grass, orchard grass, and other species, depending on region. Hay may also include legumes, such as alfalfa (lucerne) and clovers (red, white and subterranean). Legumes in hay are ideally cut pre-bloom. Other pasture forbs are also sometimes a part of the mix, though these plants are not necessarily desired as certain forbs are toxic to some animals.

Hay (song)

"Hay" is the lead single from Crucial Conflict's debut album, The Final Tic. Produced by member Wildstyle, "Hay" became the group's only charting single and their breakthrough hit, peaking at No. 18 on the Billboard Hot 100 and No. 2 on the Hot Rap Singles chart. The single was certified gold by the RIAA on July 18, 1996, and helped the album reach gold status less than two months later. It appears to have a sample of Funkadelic's "I'll Stay" from the album Standing on the Verge of Getting It On.
