For using HAT medium as a selective agent, human cells used for fusion must be deficient for either the enzyme HGPRT or TK, while mouse cells must be deficient for the other enzyme of this pair. Thus, one may fuse HGPRT deficient human cells (designated as TK+ HGPRr-) with TK deficient mouse cells (denoted as TK- HGPRT+). Their fusion products (hybrid cells) will be TK+ (due to the human gene) and HGPRT+ (due to the mouse gene) and will multiply on the HAT medium, while the man and mouse cells will fail to do so. Experiments with other selective media can be planned in a similar fashion.

In individuals with Coffin–Lowry syndrome, phosphorylation of transcriptional regulators is reduced due to the weakened activity of RSK2 kinase activity. RSK2 is normally activated by the ERK MAP kinase. Mutated RSK2 may be deficient for activation by ERK, or its kinase activity may be reduced despite activation by ERK. The most common mutation in RPS6KA3 is an early stop codon that fails to produce a functional protein, indicating that disease etiology most likely arises from loss-of-function effects.

Thomson Joseph Skinner (May 24, 1752 – January 20, 1809) was an American politician from Williamstown, Massachusetts. In addition to service as a militia officer during the American Revolution, he served as a county judge and sheriff, member of both houses of the Massachusetts legislature, U.S. Marshal, and member of the United States House of Representatives. He served for two years as Treasurer and Receiver-General of Massachusetts, and after his death an audit showed his accounts to be deficient for more than the value of his estate, which led to those who had posted bonds on his behalf having to pay the debt.

Cats must have both linoleic acid and arachidonic acid in their diet, due to their low production of the δ-6 desaturase enzyme. A deficiency in these fatty acids can occur if the fats in the cat's food are oxidized and become rancid from improper storage. A cat will be deficient for many months prior to seeing clinical signs in the skin, after which the skin will become scaly and greasy, while the coat will become dull. To treat health concerns caused by a deficiency of fatty acids, the ratio of n-3 to n-6 fatty acids must be corrected and supplemented.

The British personal equipment used in the Second Boer War had been found to be deficient for a number of reasons and the Bandolier Equipment was introduced as a stop-gap replacement. The equipment was made of brown leather and consisted of five 10-round ammunition pouches worn over one shoulder on a bandolier, with an associated waist belt and pouches, and a haversack and water bottle. It soon proved to be unsuitable for infantry use, but was used throughout the First World War by cavalry and other mounted troops. The cavalry version of the 1903 Equipment had a further four ammunition pouches on the bandolier, worn on the soldier's back, giving a total of 90 rounds carried.

Bloomberg report NP 13 August The academic community commented in 2011 that increased concentration of H2S was observed in the field and presented challenges such as "health and environmental risks, corrosion of wellbore, added expense with regard to materials handling and pipeline equipment, and additional refinement requirements".Holubnyak et al, SPE 141434-MS Holubnyak et al. write, further, that Bakken crude "may become soured through current oil field practices". At issue in the Lac-Mégantic derailment, then, is whether World Fuel Services and other defendants ought to have been aware of this two-year-old research when they ordered the DOT-111 tank cars (which were already in 2012 acknowledged by the US NTSB regulator to be deficient for these purposes) to be loaded on the Lac-Mégantic train.

In its first pamphlet, published in May 1852, the Society set out its rules for emigrants: # The Emigration will be conducted, as much as possible, by entire families, and in accordance with the rules of the Colonial Land and Emigration Commissioners. # Passages to Australia are provided by the Commissioners, from Colonial funds, for able- bodied men and women of good character ... on production of a stated quantity and description of clothing, and on payment of a deposit ... # The Society will advance the sum necessary to make good whatsoever may be deficient for these purposes ... The emigrants will he required to repay to the Society the whole of the sums advanced to them, which will again be applied in the same manner as the original fund. # The owners or trustees of the properties from which the emigrants depart will be expected to pay one-third of the sum disbursed on account of the emigrants by the Society. The last rule, which required landlords to partially fund the emigration of their tenants, has been criticized.
