Just as the cell is the smallest and most basic unit of life, the atom is the smallest and most basic unit of matter. Every atom is comprised of a set number of protons and neutrons that are orbited by small, negatively-charged particles known as electrons. All elements, ...

aShifts in the elemental stoichiometry of organisms in response to their ontogeny and to changing environmental conditions should be related to metabolomic changes because elements operate mostly as parts of molecular compounds. 因为元素经营主要作为分子化合物的部分转移在有机体中自然力化学计量学以回应他们...
The distribution of heavy metals, nitrates and other elements and compounds was studied in the Donets Basin biosphere. The neomineralization processes in burning coal waste heaps were investigated. More than 10 minerals were found for the first time in the Donets Basin; the most frequently ...
A programmer who is unfamiliar with Java, and who reads the automatically generated documentation for File, FileInputStream and BufferedInputStream, is very unlikely to be able to figure out which elements to use, or assemble the elements into working code. The great irony of Java is that, ...
摘要: In this paper we give the first example of a non-dynamically coherent partially hyperbolic diffeomorphism with one-dimensional center bundle. The existence of such an example had been an open question since 1975 [2] .关键词: Magnetic Properties of Metals Actinide Elements and their ...
