Issues of the nomenclature and typification of four species of Geraniaceae described by Turczaninow from Australia and New Zealand are discussed. It is emphasized that holotypes or syntypes of all taxa described by Turczaninow in his Animadversiones series of articles are deposited in the Turczaninow historical herbarium at KW, unless noted otherwise in the protologue. Lectotypes are designated here for the names Geranium homeanum Turcz. (KW, second-step lectotypification), Erodium peristeroides Turcz. (KW), Pelargonium stenanthum Turcz. (K, to replace the lost holotype formerly held in KW), and P. inodorum Willd. (B, second-step lectotypification). Taxonomic identities of some names are discussed: Geranium homeanum and Pelargonium drummondii Turcz. (holotype in KW) are currently accepted species, Erodium peristeroides is considered a synonym of Pelargonium inodorum, and P. stenanthum is a synonym of P. littorale Huegel.

<p>The early 1900’s saw a Norwegian Whaler’s base formed on Stewart Island where they shipped prefabricated buildings from Norway to create a settlement. The majority of these kitset buildings are still standing and apparently have had little modification from their original form. These buildings have no documentation of their materials, suitability of site or analysis of their current condition in this foreign environment. Initial research found one book by J.P.C Watt from the 1980’s which researches the Ross Sea whalers with little focus on the architecture or design. The book documents the movements of the buildings from their original service as a whaling station in the early 1900’s. This is an interesting ensemble of nomadic buildings, foreign to New Zealand, being moved around consistently and yet still remaining in the country today. Through the investigation of materiality, tectonics and individual building elements the research demonstrates how the buildings reacted to their nomadic inhabitants and also how the materials allowed for a sense of personal belonging to occur. This research aims to explore the materiality of Norwegian portable architecture and the material’s present conditions. It establishes that the nomadic/temporal nature of the Norwegian kitset buildings were not adapted to fit the New Zealand context and documents these buildings for future reference. The first step is literature research and design exploration of Norwegian kitset materials, tectonics and components. In the second step, analysis of case studies is conducted. Findings have been judged upon functionality, and therefore the design is a result of the site context and research.</p>

Our collaboration involves groups in Denmark, the U.S.A. Spain and of course New Zealand. Combining ground-based and satellite (IUEandHST) observations we aim to determine accurate and precise stellar fundamental parameters for the components of Magellanic Cloud Eclipsing Binaries as well as the distances to these systems and hence the parent galaxies themselves. This poster presents our latest progress.

The structural damage of molecules irradiated by electrons is generally considered to occur in two steps. The direct result of inelastic scattering events is the disruption of covalent bonds. Following changes in bond structure, movement of the constituent atoms produces permanent distortions of the molecules. Since at least the second step should show a strong temperature dependence, it was to be expected that cooling a specimen should extend its lifetime in the electron beam. This result has been found in a large number of experiments, but the degree to which cooling the specimen enhances its resistance to radiation damage has been found to vary widely with specimen types.

The Type I simple cold block device was described by Bullivant and Ames in 1966 and represented the product of the first successful effort to simplify the equipment required to do sophisticated freeze-cleave techniques. Bullivant, Weinstein and Someda described the Type II device which is a modification of the Type I device and was developed as a collaborative effort at the Massachusetts General Hospital and the University of Auckland, New Zealand. The modifications reduced specimen contamination and provided controlled specimen warming for heat-etching of fracture faces. We have now tested the Mass. General Hospital version of the Type II device (called the “Type II-MGH device”) on a wide variety of biological specimens and have established temperature and pressure curves for routine heat-etching with the device.

Protein A-gold immunocytochemistry is a two-step, post-embedding labeling procedure which may be applied to tissue sections to localize intra- and extracellular proteins. The key requisite for immunocytochemistry is the availability of the appropriate antibody to react in an immune response with the antigenic sites on the protein of interest. During the second step, protein A-gold complex is reacted with the antibody. This is a non- specific reaction in that protein A will combine with most IgG antibodies. The ‘label’ visualized in the electron microscope is colloidal gold. Since labeling is restricted to the surface of the tissue section and since colloidal gold is particulate, labeling density, i.e., the number of gold particles per unit area of tissue section, may be quantitated with ease and accuracy.

This cytochemical study was designed to investigate early metabolic changes in the aortic wall that might lead to or accompany development of atherosclerotic plaques in rabbits. The hypothesis that the primary cellular alteration leading to plaque formation might be due to changes in either carbohydrate or lipid metabolism led to histochemical studies that showed elevation of G-6-Pase in atherosclerotic plaques of rabbit aorta. This observation initiated the present investigation to determine how early in plaque formation and in which cells this change could be observed.Male New Zealand white rabbits of approximately 2000 kg consumed normal diets or diets containing 0.25 or 1.0 gm of cholesterol per day for 10, 50 and 90 days. Aortas were injected jin situ with glutaraldehyde fixative and dissected out. The plaques were identified, isolated, minced and fixed for not more than 10 minutes. Incubation and postfixation proceeded as described by Leskes and co-workers.
