Dimethoxyamphetamine (DMA) is a series of six lesser-known psychedelic drugs similar in structure to the three isomers of methoxyamphetamine and six isomers of trimethoxyamphetamine. The isomers are 2,3-DMA, 2,4-DMA, 2,5-DMA, 2,6-DMA, 3,4-DMA, and 3,5-DMA.
Moving average crossover of a 15-day exponential close-price MA (red) crossing over a 50-day exponential close-price MA (yellow) In the statistics of time series, and in particular the stock market technical analysis, a moving-average crossover occurs when, on plotting two moving averages each based on different degrees of smoothing, the traces of these moving averages cross.
CH 3 CON(CH 3) 2 + H 2 O + HCl → CH 3 COOH + (CH 3) 2 NH 2 + Cl −. However, it is resistant to bases. For this reason DMA is a useful solvent for reactions involving strong bases such as sodium hydroxide. [7] Dimethylacetamide is commonly used as a solvent for fibers (e.g., polyacrylonitrile, spandex) or in the adhesive industry. [5]
For example, the 50-day moving average represents the stock’s average price over the past 50 days of trading. In the case of the 200-day moving average, it shows the stock’s average closing ...
In a distribution, full width at half maximum (FWHM) is the difference between the two values of the independent variable at which the dependent variable is equal to half of its maximum value. In other words, it is the width of a spectrum curve measured between those points on the y -axis which are half the maximum amplitude.
2,5-Dimethoxyamphetamine (2,5-DMA), also known as DMA-4 or as DOH, is a drug of the phenethylamine and amphetamine families. [1] [2] It is one of the dimethoxyamphetamine (DMA) series of positional isomers. [1] [2] The drug is notable in being the parent compound of the DOx (4-substituted-2,5-dimethoxyamphetamine) series of drugs. [1] [2]
The EC 50 of a quantal dose response curve represents the concentration of a compound where 50% of the population exhibit a response, [5] after a specified exposure duration. For clarification, a graded dose response curve shows the graded effect of the drug (y axis) over the dose of the drug (x axis) in one or an average of subjects.
Likewise, the plasma half-life of -MDMA was significantly longer than that of the (S)-enantiomer (5.8 ± 2.2 hours vs 3.6 ± 0.9 hours). [77] However, because MDMA excretion and metabolism have nonlinear kinetics, [ 215 ] the half-lives would be higher at more typical doses (100 mg is sometimes considered a typical dose).
