In enzymology, a phenol O-methyltransferase (EC 2.1.1.25) is an enzyme that catalyzes the chemical reaction. S-adenosyl-L-methionine + phenol S-adenosyl-L-homocysteine + anisole. Thus, the two substrates of this enzyme are S-adenosyl methionine and phenol, whereas its two products are S-adenosylhomocysteine and anisole.
Parent management training (PMT), also known as behavioral parent training (BPT) or simply parent training, is a family of treatment programs that aims to change parenting behaviors, teaching parents positive reinforcement methods for improving pre-school and school-age children's behavior problems (such as aggression, hyperactivity, temper tantrums, and difficulty following directions).
Each influential factor is generally measured by asking questions through a survey. For example, Boer (2005) studied on intention of condom use to prevent from getting AIDS guided by protection motivation theory. The study asked the following questions to individuals: "If I do not use condoms, I will run a high risk of getting HIV/AIDS."
The device achieved gains of 1000x or more when demonstrated in June 1934. The work was submitted for print publication only two years later, in July 1936 [11] as emphasized in a recent 2006 publication of the Russian Academy of Sciences (RAS), [12] which terms it "Kubetsky's Tube." The Soviet device used a magnetic field to confine the ...

Several languages of Wikipedia also maintain a reference desk, where volunteers answer questions from the general public. According to a study by Pnina Shachaf in the Journal of Documentation , the quality of the Wikipedia reference desk is comparable to a standard library reference desk , with an accuracy of 55 percent.
The reaction is extremely rapid with a second order rate constant of 2000 M −1 –s −1 (in 9:1 methanol/water) allowing modifications of biomolecules at extremely low concentrations. Based on computational work by Bach, the strain energy for Z-cyclooctenes is 7.0 kcal/mol compared to 12.4 kcal/mol for cyclooctane due to a loss of two ...
[140]: 153 Domestic cats are a major predator of wildlife in the United States, killing an estimated 1.3 to 4.0 billion birds and 6.3 to 22.3 billion mammals annually. [141] Certain species appear more susceptible than others; in one English village, for example, 30% of house sparrow mortality was linked to the domestic cat. [142]
