A and 5 show results for a period during and after harvest, in October and November, 1978. Generation of soil aerosol by tilling was observed, and wind erosion was possible, during this period because of the removal of the crop cover from the soil surface. Figure A shows results of three weeks of sample collection from the ground site, and

A and are very similar, showing that both polypeptides have five hydrophobic segments. Each of these hydrophobic segments contains enough amino acids to form a membrane-spanning a-helix. Note that the residue-number scale strictly applies only to the L- and H-polypeptides that for the M-polypep-tide has been shifted in order to maximize the coincidence of its hydrophobic regions with those of the L-polypeptide. The hydropathy plot for the H-polypeptide

A and B are microswitches for reversing the stepping motor C D is heating elements and E is the wire to the controller box. The heaters are several turns of nichrome wire, and the mbe is 8 mm Pyrex closed at the bottom. The heaters are moved up the tube by a screw attached to a stepping motor. At the top of the tube, a mieroswitch turns off the heaters, and the stepping motor is returned automatically to the bottom of the tube. The wiring diagram, which is not all that difficult, is presented in J. Chem. Ed, 59 , 63,1982 by G.F. Needham, G. Boehme, R.D. Willitt, and
