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.

Candidate of Philosophy

Candidate of Philosophy is any of the following academic degrees: a Bachelor's level, Master's level, higher than Master's level, or Doctorate level degree, depending on the country.

In the United States

The usual practice in the United States is for a graduate student working toward a doctorate to earn a master's degree (usually Master of Arts or Master of Science) in course after about two years of coursework. In a very few universities, a student who has completed all of the coursework, all of the comprehensive examinations in the subject and all of the language examination requirements, and whose dissertation topic has been approved - in short, who has fulfilled all requirements for the doctorate except the writing and defense of the dissertation itself - may be awarded a Master of Philosophy degree, beyond the Master of Arts or Master of Science already earned. In other universities, such students used the informal designation of Ph.D. (ABD), for "All But Dissertation," not an actual degree but an informal convention.

Triphenylmethyl hexafluorophosphate

Triphenylmethyl hexafluorophosphate is an organic salt with the formula C(C₆H₅)₃PF₆. This compound is a brown powder that is air sensitive and changes colors when exposed to light. Triphenylmethyl hexafluorophosphate is used as a catalyst and reagent in organic syntheses.

Preparation

Triphenylmethyl hexafluorophosphate is generated by two ways. The first method is by combining silver hexafluorophosphate with triphenylmethyl chloride:

The second method of generating triphenylmethyl hexafluorophosphate is through the reaction of triphenylmethyl chloride with an ether complex of hexafluorophosphoric acid:

Triphenylmethyl chloride is afforded by combining carbon tetrachloride and benzene in a Friedel-Crafts reaction.

Structure and Properties

The trityl group can exist in three oxidation states: the trityl cation, the trityl radical, and the trityl anion. The trityl cation is the form present in triphenylmethyl hexafluorophosphate. The triphenylmethyl cation effectively has D3h molecular symmetry.
