Propagule pressure plays an important role in species invasions (Groom, 2006). Charles Darwin was the first to study specific factors related to invasions of non-native species. In his research he identified that few members of the same genus were present in habitats containing naturalized non-indigenous species (Colautti et al., 2006).
In 1999, Metabolite sued LabCorp for infringement of a patent covering a diagnostic test. The single claim at issue, claim 13, is reproduced in full below: "A method for detecting a deficiency of cobalamin or folate in warm-blooded animals comprising the steps of: "assaying a body fluid for an elevated level of total homocysteine; and "correlating an elevated level of total homocysteine in ...
The general expression Qualitative Analysis [...] refers to analyses in which substances are identified or classified on the basis of their chemical or physical properties, such as chemical reactivity, solubility, molecular weight, melting point, radioactivity properties (emission, absorption), mass spectra, nuclear half-life, etc. Quantitative Analysis refers to analyses in which the amount ...
The 2006 term of the Supreme Court of the United States began October 2, 2006, and concluded September 30, 2007. The table illustrates which opinion was filed by each justice in each case and which justices joined each opinion.
A blank solution is a solution containing little to no analyte of interest, [1] usually used to calibrate instruments such as a colorimeter. According to the EPA, the "primary purpose of blanks is to trace sources of artificially introduced contamination." [2] Different types of blanks are used to identify the source of contamination in the ...
Chemical structures are traditionally represented using lines indicating chemical bonds between atoms and drawn on paper (2D structural formulae).While these are ideal visual representations for the chemist, they are unsuitable for computational use and especially for search and storage.
HSAB is widely used in chemistry for explaining the stability of compounds, reaction mechanisms and pathways. It assigns the terms 'hard' or 'soft', and 'acid' or 'base' to chemical species . 'Hard' applies to species which are small, have high charge states (the charge criterion applies mainly to acids, to a lesser extent to bases), and are ...
In 1995, the Department of Chemistry at Texas A&M along with the local section of the American Chemical Society, inaugurated the annual F.A. Cotton Medal for excellence in chemical research. A second award named in his honor, the F. Albert Cotton Award for Synthetic Inorganic Chemistry, [ 15 ] is presented at the National Meeting of the ...
