The objective of this thesis is to examine and compare hot
metal and cold type production of display advertising for newspapers.
The classical hot metal system uses a lead alloy as its basic building
material while modern cold type production uses photographic
means. Some advantages of using cold type are...
The infrared absorption spectra in the out-of-plane
bending (v₂) region of potassium nitrate were studied for
three phases. Several types of sampled were used: nujol
mulls, fused samples, and N¹⁴-N¹⁵ isotopic mixtures. The
existence of three of the reported polymorphic phases was
confirmed by the spectra. The transitions between phase...
A pharmacognostic study was made of the root of Heracleum
mantegazzianum, an umbelliferous species which is of value as a
source of natural coumarins.
Three groups of seeds were tested to determine the presence
of a germination requirement for moist cold and the possible value
of gibberellic acid in obviating...
The coagulation of effluent from the kraft pulping and
papermaking process was investigated. The amount of material
coagulated from saline mixtures of the effluent is determined
as a function of time, salinity, kraft effluent
concentration, and mixture pH. Individual sources of salinity
include sea water and several different solutions of...
ENTOMOLOGISTS, BOTANISTS, and AGRICULTURISTS all
have occasion to concern themselves with bees. The en-tomologist is fascinated by their complex behavior pat-terns, the botanist needs to evaluate their significance infloral biology, and the agriculturist must take them into account as vital factors in crop production. Finally, the apiculturist often wishes to...
