Because these elements are so similar to each other, the process of separating them is time consuming, expensive, and dangerous.
However, determining the maturity of a specimen based only on the fusion of arches with centrum is not safe because these elements are size-independent65.
Because these elements are very similar chemically, their separation presented numerous problems before the advent of ion-exchange methods and ion-specific complexing agents such as crown ethers.
These vapours or fluids must contain fluorine, boron, and probably lithium, because these elements are contained in topaz, mica, and tourmaline, the new minerals of the granite.
The second fact is key for high-level radioactive waste management, because these elements are the main responsible for the radioactivity of the irradiated fuel in the long term.
The presence of V, As, Sr, Mo, Ba and U in ground water was not surprising, because these elements are naturally occurring elements (WHO 2008; AWWA 2014a).
Because they are magnetic, these elements are easily captured, at which point they can be analyzed or clonally expanded.
This is because unlike one-dimensional elements, these elements are able to simulate the propagation of the tensile cracks along the height of the pier, i.e. geometrical nonlinearity.
In the phylogenetic study, we analysed the autonomous and nonautonomous subfamilies separately because the internal regions of these elements are rather dissimilar in their sequences.
The majority of these elements are inactive because of truncation, mutation, and/or heavily rearranged sequences [7].
Because of the absence of MuDR, these elements are dormant, and some may have lost their transposition activity due to accumulated mutations.
