    2011-7-1 · Attention was then turned to microscopic features of cavitation through a careful quantification of void density and shape factor by means of a method coupling a SEM with an image analysis procedure. At the two scales of interest, the results demonstrate that (i) the void density generated by crazing in neat HDPE or particle-matrix debonding in ...

    2. Nonionic Surfactants. 2-1. Polyoxyethylene (POE) Surfactants. A POE (also referred to as alkylphenol ethoxylate, or APE) are also “old chemistry” wetting agents. The original AquaGro contained a POE. Like the anionic group of surfac - tants, POEs also can be phytotoxic to fine turf when used in some situations. POEs were originally ...

  • Quantitative Assessment of Coronary Microvascular

    2009-9-3 · Profinity IMAC uses IDA as its functional ligand. The tertiary amine and carboxylic acid side chains of IDA serve as the chelating ligands for di- or trivalent metal ions. The structure offers selective binding of recombinant His-tagged proteins when this resin is charged with Ni2+ or other transition metals. As a result, the desired

  • Understanding The Different Wetting Agent Chemistries

    2020-1-31 · The quantification range of the method was 0.1 to 1000 nmol Gd/L in solutions, corresponding to a lower limit of quantification (LOQ) of 0.01 nmol Gd/g in wet tissue. For all fractions, the measured Gd concentrations were converted to tissue concentrations (nmol Gd/g wet tissue) taking all dilutions and separation steps into account.

    2010-8-25 · Let me turn to the kind of quantitative and qualitative evaluation I have pursued for almost four decades. In 1961, we had to make quick decisions about which journals to cover in the Science Citation Index . ® We had some experience with Current Contents ® so we were especially interested in current impact. Over the past 35 years, ISI's journal coverage has grown from 600 to over 8,000 ...
