Nuclear magnetic resonance spectroscopy of proteinsNuclear magnetic resonance spectroscopy of proteins (usually abbreviated protein NMR) is a field of structural biology in which NMR spectroscopy is used to obtain information about the structure and dynamics of proteins, and also nucleic acids, and their complexes. The field was pioneered by Richard R. Ernst and Kurt Wüthrich at the ETH, and by Ad Bax, Marius Clore, Angela Gronenborn at the NIH, and Gerhard Wagner at Harvard University, among others.
Microscopie électronique en transmissionvignette|upright=1.5|Principe de fonctionnement du microscope électronique en transmission. vignette|Un microscope électronique en transmission (1976). La microscopie électronique en transmission (MET, ou TEM pour l'anglais transmission electron microscopy) est une technique de microscopie où un faisceau d'électrons est « transmis » à travers un échantillon très mince. Les effets d'interaction entre les électrons et l'échantillon donnent naissance à une image, dont la résolution peut atteindre 0,08 nanomètre (voire ).
PsychographicsPsychographics is defined as "market research or statistics classifying population groups according to psychological variables" The term psychographics is derived from the words “psychological” and “demographics” Two common approaches to psychographics include analysis of consumers' activities, interests, and opinions (AIO variables), and values and lifestyles (VALS). Psychographics have been applied to the study of personality, values, opinions, attitudes, interests, and lifestyles.
