A normal phase HPLC methodology using a semi-preparative polyaminocyano column in conjunction with a selection of short-term genotoxicity assays has been developed for bioassay-directed fractionation studies of complex environmental mixtures. To illustrate the effectiveness of this methodology, an organic ...

In cases where it was not clear from the methodology whether randomisation was performed, the authors were contacted by e-mail for clarification. Results An initial search of PubMed was conducted that identified 23 possible RCTs. After the full text of each study was obtained and reviewed, 17...
in . In the case where these quantities grow to infinity, these growth rates had once been termed “orders of infinity” – for instance, in the 1910 book of this name by Hardy –although this term has fallen out of use in recent years. (Hardy fields are still a thing, though.) ...
would be extremely difficult for shorebirds in the arctic because the needed sample size would be unobtainable (in Canada at least) and the level of effort that would need to be expended (both financial and human resource-wise) would far exceed that of the current Arctic PRISM methodology. Fo...
The dynamic model formulation employed here contains the following layers of nonlinearity: nonlinear response of the equilibrium cumulative carbon to GMST changes, represented by the ωφω(T)·T term; evolution of the characteristic time lag for cumulative permafrost emissions with the difference ...
While I travel less these days, it is always so rewarding to meet former students who have put the “Disciplined Entrepreneurship” methodology to work to create jobs and make the world a better place. There were several at the conference whom I took pictures with, but wo...
The SSD parameters, µ (median of the log-transformed toxicity values) and σ (standard deviation of log-transformed toxicity values or slope), for short and long-term effects, were calculated with acute (Effect Concentration for the 50% of the individuals, EC50) and chronic toxicity data (...
