Infrared and optical polarimetry of AM Herculis
Circular polarization observations of AM Herculis have been obtained at wavelengths from 0.55 micron (V) to 2.2 micron (K) using a simultaneous three-channel polarimeter. Polarizations of up to 20 per cent were observed ...
Imaging and polarimetry of the galactic-center in the near infrared
IR images of the Galactic center in H, K, L-prime and M are the bases of the present measurements of positions, magnitudes and colors for 35 sources which can be divided into two classes: those with colors typical of ...
Effect of cellulose xanthate on splash dispersal of Pseudocercosporella herpotrichoides spores
Cellulose xanthate reduced dispersal of Pseudocercosporella herpotrichoides spores from wheat straw by simulated rain.
The effect of context during word perception in schizophrenic patients
Hospitalized chronic and acute schizophrenics were compared with age- and social-status-matched controls on word perception tests to measure the effect of context on recognition thresholds. In Experiment 1 the method of ...
The extraction of total RNA by the detergent and phenol method
Successful extraction of RNA depends on the quantitative recovery of pure nucleic acids in an undegraded form. In practice, this means that a selective extraction process is required to remove all the unwanted cellular ...
