Oregon crab condition studies during the 1960-61, 1961-62, 1962-63, and 1963-64 seasons

Creator:: Snow, C. Dale and Oregon. Fish Commission. Shellfish Investigations
Abstract:: Each year, after crabs molt, there is a time when their shells are soft, and are not filled up with crab meat. This soft-shelled state is undesirable for fishers. Since the timing of molting varies from year to year, it is difficult for fishery managers to set the start date...

Hydraulic clam harvesting

Creator:: Snow, C. Dale and Oregon. Fish Commission. Shellfish Investigations
Abstract:: "During the summer of 1961, a seafood dealer at Charleston, Oregon hired SCUBA ... divers to harvest clams in subtidal areas with hydraulic equipment. This operation proved to be quite efficient and was attended by considerable publicity. During the summer of 1962, several commercial and personal-use diggers equipped themselves with...

The reproduction and mode of spread of sago pondweed (Potamogeton pectinatus L.) in irrigation system

Creator:: Ogg, Alex G.
Abstract:: Nine experiments were conducted during 1964 and 1965 to study the methods of reproduction and mode of spread of sago pondweed (Potamogeton pectinatus) in irrigation systems. Frequent treatments of sago pondweed foliage with aromatic solvent greatly reduced the number of tubers in the substratum of an irrigation canal. However, complete...

Correlations between horticultural characteristics and Fusarium root-rot resistance in Phaseolus vulgaris L.

Creator:: Wang, Theodora
Abstract:: To study the association between Fusarium root-rot resistance (Fusarium solani f. sp. phaseoli) and economically inportant characteristics of beans, 2259 lines each consisting of 30 plants were used. The lines were randomly selected for root-rot reaction, but were selected for differences in vigor and differences in plant and seed pigments,...

Decomposition of di-p-toluenesulfonyl-hydrazones

Creator:: Bradway, Diane Elizabeth
Abstract:: Thermal decomposition of several di-p-toluenesulfonylhydrazones was studied. It was found that the carbene decomposition of tetramethyl-1,3-cyclobutanedione, di-p-toluenesulfonylhydrazone gave two products resulting from rearrangement. One was identified as 2,5-dimethyl-1,3,4-hexatriene. A tentative structure for the second was proposed. During the course of the study, a more convenient procedure for thermal decompositions was...

Percussive-welded p-n junctions in silicon

Creator:: Tao, David Ming-Shih
Abstract:: This thesis investigates a way to fabricate P-N junctions by percussive welding. The theoretical basis of percussive welding, design considerations of the apparatus used, and the electrical characteristics of the junctions were the main objectives of this investigation. P-type silicon wafers and gold wire doped with arsenic as a N-type...

A comparative study of the isozymic proteins and the effect of metachemogenesis in the tissues of Periplaneta americana (L.)

Creator:: Beckendorf, Gerald Walter
Abstract:: An attempt was made to demonstrate isozymic forms of esterase, MDH, LDH and GPDH and the variation in enzyme pattern with increasing age in the thoracic muscle, appendage muscle and hemolymph of the American cockroach, Periplaneta americana. Sampled specimens of both sexes were aged one through seven days, two weeks...
