A. ANTIBODY RESPONSES OF HUMAN TONSILLAR LYMPHOCYTES. 1 Human tonsillar lymphocytes were stimulated with pokeweed mitogen in vitro. A large number of cells developed which secreted antibody specific for sheep erythrocytes. The largest number of antibody-forming cells was produced on days 4 or 5, when optimal cell concentrations were used. Responses specific for bovine and horse erythrocytes were much smaller than those specific for sheep erythrocytes. 2 Antibody responses were studied using a cu...

The crystal and molecular structures of five binary complexes between transition-metal ions and 5'-ribonucleotides have been determined by X-ray crystallographic means. All data were collected by diffractometry and the structures refined by the full-matrix least-squares method. The complex Ni (C10H11N4O8P) (H2O) 5. 2H2O crystallizes in the orthorhombic space group P212121 with four molecules in a unit cell of dimensions a = 6.853(1), b = 10.812(2), c = 25.925 (3) Å. Refinement converged with...

1. The major phospholipids extracted from Bacillus amylolique - faciens were cardiolipin, phosphatidylycerol and phosphatidylethanolamine. 2. The distribution of these phospholipids between the two halves of the cytoplasmic membrane bilayer was studied using phospholipase C ( B. cereus ), phospholipase A2 ( Crotalus ) and the non - penetrating chemical probe trinitrobenzenesulphonic acid ( TNBS ). After treatment of intact protoplasts of B. amylolique - faciens with either phospholipase, approxi...

keratin, bacteriophages, chromosome mapping, molecular genetics

Restriction enzyme, molecular cloning and DNA annealing techniques have been used to study mRNA and DNA coding for the embryonic feather keratins of the chicken and the DNA genomes of coliphages 186 and P2. The coliphage DNAs were used to develop the techniques for application to the keratin system which awaited the availability of appropriate bio - hazard containment facilities before being undertaken. The following results were obtained. 1. Restriction endonuclease cleavage of chick DNA with B...

This model study is concerned with attempting to identify some of the mechanics of pile-soil interaction under the influence of static loads, as a pre-requisite to defining the mechanics of the soil response to pile transmitted dynamic (i.e. seismic) lateral soil loads. The emphasis has been directed at the mechanics of the response of the soil to loads transmitted through the pile, rather than the more usual approach of defining an analytical pile model and assuming a soil response. The work co...

The work described in this thesis is an analytical and experimental study of two-phase gas-liquid horizontal flow in a conduit with particular emphasis on holdup measurements and predictions. Holdup and pressure drop, their inter-relationships, and their flow pattern dependence were investigated. A simple method for flow pattern determination was presented so that the appropriate prediction method may be selected for a particular situation. The results were discussed by comparison with a wide ra...

This study examines the influence of an extension agency, the Ministry of Agriculture and Fisheries Advisory Services Division, in stimulating the diffusion of innovations among farmers in New Zealand. Consideration of the Farm Advisory Officers’ objectives and the rationale for their extension strategies provides a background for investigating and accounting for their use of different techniques. The effectiveness of these techniques is examined, within the framework of an adoption-stimulation ...
