abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
This chapter provides a comprehensive survey of the motivations, assumptions and pitfalls associated with combining signals such as fMRI with EEG or MEG. Our initial focus in the chapter concerns mathematical approaches for solving the localization problem in EEG and MEG. Next we document the most recent and promising ways in which these signals can be combined with fMRI. Specifically, we look ...
Rapid global change has increased interest in developing ways to identify suitable refugia for species of conservation concern. Correlative and mechanistic distribution models (SDMs) represent two approaches generate spatially-explicit estimates climate vulnerability. SDMs distributions using statistical associations between environmental variables presence data. In contrast, use physiological ...
The ability to use GFP-tagged proteins to perform correlative light and electron microscopy has been a desirable but elusive method. The high quantum yield of GFP that makes it excellent for fluorescence imaging also makes it extremely inefficient for production of the reactive oxygen needed to trigger formation of an electron-dense precipitate for electron microscopy. This roadblock has finall...
