However, by the time laboratory strains are found to be contaminated, research time and effort have already been consumed.
In this paper, we propose a singular spectrum analysis (SSA) method with novel grouping criteria to remove spikes from highly contaminated velocity time series.
Let (y_{t}), (t=1,...,T), be a stationary series with finite fourth-order moment that is contaminated from time (tau ) onwards by k consecutive outliers with the same sign and size, (omega ).
The Agnew Greenstone Belt records ∼30 m.y. of episodic ultramafic mafic magmatism that includes two cycles, each defined by a komatiite that is overlain by units that become more evolved and contaminated with time.
Broken and humiliated from his Cross Jesus reigns, paradoxically, through altruistic self-sacrifice over a kingdom which, says he to Pilate, is 'not of this world.' Conversely, the Prophet is remembered as being Allah's chosen messenger in restoring all seekers of true faith to its original Abrahamic model - ostensibly contaminated over time only to be revealed to him generations later.
Erban and colleagues reviewed arsenic measurements from nearly 43,000 deep wells in the Mekong Delta and found that many of them had become contaminated over time.
Testing kit proves water is contaminated Some time later, when the testing kit has done its work, one whiff from the bottle confirms that the well water is polluted, so now Gayanthika and her classmates begin boiling it.
The PCR-based methods are popular at present, but they are easily contaminated and time-consuming sometimes.
The report found a statistical "association" between infant leukemia and women who lived in the area of the old plant and who reported in interviews that they had consumed tap water from wells known to have been contaminated at the time.
Wounds in which soil or dirt are embedded are considered contaminated at the time of injury and may need to be left open if adequate debridement is uncertain, or may require a more aggressive operative washout.
Due to what the state said was the sheer passage of time, contaminated evidence, and a lack of living witnesses, it would not be able to prove that Lapointe was guilty beyond a reasonable doubt.
