The size and development stage of maggots can be used to give a measure of the minimum time since death. [9]: 251–252 Insect activity occurs in a series of waves, and identifying the insects present can give additional information on the postmortem interval. [10] Adipocere, or corpse wax, may be formed, inhibiting further decomposition.
Disintegration became the band's highest charting album to that point, reaching number three on the UK Albums Chart and number 12 on the US Billboard 200, and producing several hit singles, including "Lovesong", which peaked at number two on the Billboard Hot 100. It remains the band's highest-selling record to date, with more than four million ...
The time required for an atom of a parent isotope to decay into its daughter is fundamentally unpredictable and varies widely. For individual nuclei the process is not known to have determinable causes and the time at which it occurs is therefore completely random. The only prediction that can be made is statistical and expresses an average ...
Pornography and Disintegration have long been revered as two of the Cure’s best and most cohesive albums. Smith had never explicitly linked them together as part of a series until the release of ...
A more intuitive characteristic of exponential decay for many people is the time required for the decaying quantity to fall to one half of its initial value. (If N(t) is discrete, then this is the median life-time rather than the mean life-time.) This time is called the half-life, and often denoted by the symbol t 1/2. The half-life can be ...
1 Bq = 1 s −1. A special name was introduced for the reciprocal second (s −1) to represent radioactivity to avoid potentially dangerous mistakes with prefixes.For example, 1 μs −1 would mean 10 6 disintegrations per second: (10 −6 s) −1 = 10 6 s −1, [4] whereas 1 μBq would mean 1 disintegration per 1 million seconds.
The decay scheme of a radioactive substance is a graphical presentation of all the transitions occurring in a decay, and of their relationships. Examples are shown below. It is useful to think of the decay scheme as placed in a coordinate system, where the vertical axis is energy, increasing from bottom to top, and the horizontal axis is the proton number, increasing from left to right.
Half-life (symbol t ½) is the time required for a quantity (of substance) to reduce to half of its initial value.The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive.
