The use of physical and chemical techniques in the identification of Tephera (volcanic ash) in the North Island, New Zealand
No full textField evidence is no longer adequate to resolve the problems of tephrostratigraphy, particularly in areas far from the likely volcanic source. In such areas the deposits are thin, and consequently more strongly weathered, as they are more or less continually involved in soil development processes. Under such conditions lithologic resemblance of a given ash to the same material closer to source may be lacking. The identification and correlation of tephra in the Waikato Basin of the North Island of New Zealand is one such example. These tephra form the parent materials of the agricultural soils of the region, and are at considerable distances from the likely sources, these being the Egmont volcanic centre in Taranaki, the Okataina volcanic centre in the Bay of Plenty, and the Tongariro and Taupo volcanic centres in the Central North Island. In particular, this thesis sought to resolve the problem of the identity of the Tirau and Mairoa Ash beds; whether they merely represent the products of pedogenesis of the same parent materials under differing weathering conditions.
In the resolution of this problem, many laboratory techniques were exhaustively and systematically investigated, the methods being reviewed and extended in their applicability and their sensitivity being improved where possible. Physical properties of the rhyolitic glass associated with the samples that were found to provide useful data were refractive index, density, and magnetic properties.
(a) Refractive index: This classical method of determination of a parameter indicative of bulk composition was improved an order of magnitude over that typical for petrologic investigation by the development of a thermal variation method. The increased sensitivity so obtained enabled the use of this parameter in the correlation of glass shards. The use of refractive index for this purpose had previously been abandoned because of its lack of sensitivity.
(b) Specific gravity: The determination of density was investigated by gradient techniques using solutions of acetone in bromoform. The natural variation in density exceeded the precision of the technique, but in spite of this the method was shown to have some application in the solution of tephrostratigraphic problems.
(c) Magnetic properties: Simple methods based on the Guoy magneto-balance were found to provide useful information on the magnetic susceptibility of glass, and were found to be particularly useful in the attempted correlation of the Aokautere and Teviotdale Ashes. More generally, the magnetic susceptibility was found to be a ready method of assessing the ferrous contents of glasses.
In addition to these physical methods the glasses were analysed chemically. As well as these techniques, use was made of mineral assemblages, particularly of felsic minerals; and of the relative proportions of rhyolitic and andesitic glass. The former of these two glasses is easily extracted physically, but the existence and quantitative estimation of andesitic glass, being difficult to determine directly, was determined indirectly by infra-red spectroscopic techniques. The relative proportions of these two glasses was itself found to be a parameter of some importance in correlation and has been used in conjunction with a first-order kinetics model for the weathering of glass to allophane to provide approximate dates for the samples.
While the object of this thesis was to review and develop physical, chemical, and mineralogical techniques of use in tephrostratigraphy, the techniques were used to solve some specific tephrostratigraphic problems, in particular, problems involving thin beds in the Waikato region, and some problems in long-range tephra correlation. These specific problems investigated were:
(a) The Tirau-Mairoa Problem: There has been a long-standing debate over whether the ash beds that make up the Tirau Ash and Mairoa Ash sequences are the same or whether the parent materials differ. From the information derived by the use of the techniques described above, the two ash sequences were found to differ: the Mairoa Ash sequence being both older and more andesitic in character than the Tirau Ash sequence. The Mairoa Ash sequence was considered, as a result of this work to underlie and possibly interdigitate with the Tirau Ash. Samples from sites between the type localities of the two sequences shoved a composite character. Chemical analysis of the rhyolitic glass and refractive index data suggested, that at least in some localities, the Mairoa Ash was contaminated with material from the underlying Oruanui Formation.
(b) Oruanui-Aokautere Correlation: The Oruanui Formation is a widely distributed bed or sequence of beds in the central North Island and had been previously tentatively correlated with the Aokautere Ash in the southern part of the North Island. Application of the techniques developed in this thesis confirm this correlation specifically between the Oruanui Ash and the Aokautere Ash.
(c) Oruanui-Teviotdale Correlation: The Teviotdale Ash of North Canterbury is believed by some to be correlative with the Oruanui and Aokautere Ashes. The magnetic and chemical properties, however, suggested that the Teviotdale Ash represents a separate eruption.
The soils developed on Kaharoa and Taupo Ashes show elemental deficiencies when exploited for agriculture. Soils developed on similar rhyolitic tephra of greater age show no such deficiency. Accordingly, the relative merits of such deficiencies being caused either by pedogenetic factors or by initially low amounts of the microelements in the parent materials was investigated. In the case of selenium, most of this element potentially available is to be found in the glass. Analysis of the glasses from the various ashes showed little variation in selenium content, and the results obtained bore no relationship to the agricultural selenium status of the derived soils. From this it was inferred that the selenium deficiencies are pedogenetic in origin, being caused principally by the short length of time available for the leaching of selenium from the glass. In that cobalt tends to be enriched in the more mafic minerals rather than in the glass, deficiencies of this element in the soils derived from the Kaharoa and Taupo Ashes may be rather more inherent, since the parent tephra concerned contain but small amounts of these minerals
Runoff, infiltration and soil erodibility studies in the Otutira catchment
No full textYellow-brown pumice soils cover a large area of the central North Island of New Zealand. In the Waikato River basin these soils occupy over 7,000km². Since land development started in the mid-1930s approximately 4,000km² have been converted from the native vegetation to exotic forests (1,243km²) and pasture (2,740km²), and a further 500km² could be developed.
Since about 1959 gully erosion has become more common and widespread. The causes of this erosion were not known, although many hypotheses attempting to account for erosion have been put forward. The research reported in this thesis was undertaken in an attempt to isolate the most important causes of erosion.
Three experiments have been completed.
(1) A study of runoff from plots placed in areas of pasture grass, ungrazed grass and scrub vegetation has been made. Climatic, soil, vegetation, and slope variables were studied and as a result of statistical analysis it is concluded that surface water runoff is greater from developed land in pasture and less from areas covered by scrub and ungrazed grass vegetation. The major causes of runoff from pastures are very intense rainfall on a soil with low moisture content.
(2) Infiltration studies with an infiltrometer, designed and built for the purpose, reinforce the conclusions drawn from runoff studies. They also show that modifications of soil properties, especially compaction caused by animals and vehicles, decrease infiltration and hence promote runoff.
(3) Flume studies of the erodibility of pumice soils indicate that soil particles are easily entrained by running water, but that plant roots inhibit this process. Analysis of data from the three experiments indicates that land development should be carried out so that: (a) a close vegetation cover is kept on all soils; (b) channel development is avoided; (c) vulnerable areas such as valley floors and steep valley sides are kept as water absorption areas; (d) animals and vehicles are excluded from water absorption areas to prevent soil compaction; (e) plants with strong and dense root systems are used to protect surface soils
An analysis of the surface water resources of the upper Taieri River, Otago
No full textTo plan a water resource survey data collection programme, it is vital to first establish the purpose for which the gathered data are to be used, and the degree of precision of the information at a particular confidence level that will be adequate. Purpose will determine the required data precision. Precision requirements will in turn dictate minimum record lengths of each variable necessary to estimate population parameters at a point, and the network density needed for parameter estimation over an area.
This study is concerned with the data requirements and analyses for the planning of an irrigation scheme in the Maniototo Plains and Styx Basin, Central Otago. The 95 percent confidence level is adopted for required data precision. Allowable standard errors of population parameter estimates are stated to be 10 percent for streamflow and precipitation and five percent for temperature.
Measured monthly, seasonal, and annual parameter values of these variables are summarised and discussed. Although the data collection networks are shown to be theoretically acceptable for most purposes, the measured data do not allow estimation of all the needed total - and sub-catchment population parameters at the required precision level. Record synthesis is necessary in order to increase the amount of information contained at this stage in the precipitation and streamflow data series.
Techniques chosen for time series extension and spatial extrapolation are linear7 curvilinear and multiple regression analyses, water balance, conceptual and stochastic models. Each model is described, and limitations or advantages outlined. Also discussed are the theoretical aspects which concern precision of population parameter estimates from blended data, standard errors of prediction for synthetic records, and the relative simulation and prediction abilities of the models chosen. Split-record techniques are used to evaluate within and between model efficiencies.
Addition of synthesised records to the precipitation and streamflow data series still does not permit estimates of all required population parameters at the levels of precision stated as needed. In some instances, record extension results in a decrease in statistical information. For design of any irrigation scheme to proceed now, therefore, the chosen error criteria must be judged too stringent for the Upper Taieri data. If the calculated standard errors cannot be accepted, all precipitation and streamflow records from the study area will require extension by additional observations.
The study is also used as an opportunity to check the validity of commonly. accepted concepts of 'regional hydrology', at least within the East Otago Region. It is concluded that for low flows, hydrological homogeneity cannot be assumed to equate with uniformity of basin characteristics. Regions are better defined in terms of allowable areal variation for stated hydrological parameters. The study area is not hydrologically homogeneous by the defined criteria. Further, the boundaries of hydrologically similar regions vary dependent on which streamflow parameter is considered.
Results are presented in British units throughout this study, since these are the units in which the basic data were measured and analysed
J.D. Manning: The Life of a WWII Draftee
No full textabstract: The biography of J.D. Manning tells the story of the first man drafted in the United States at the dawn of World War II. Growing up, he lived an ordinary, small-town life in Washburn, Wisconsin. However, due to a clerical error, by the time he was inducted into the military, J.D. had assumed a second identity. While listed under a different name throughout his military service, J.D. decided to turn the military into a career. He extended his service and went on to Officer Candidate School before serving in the war. Ultimately, J.D. died in the Battle of Cherbourg. His story outlines the importance of humanizing war at a time when statistics and numbers tend to impersonalize such a large, historical event. J.D.'s biography provides an understanding of how even the most ordinary, typical life of a drafted solider during WWII can produce an extraordinary story. J.D. was not special. He was but one death in a body count of over 400,000 American soldiers during the war. Yet, his story teaches us that one does not have to be special to be important. Every American soldier has made a contribution to our country, yet only a select few have ever had their stories told. This biography of J.D. will add one more story to the limited collection existing today
The surface features and soil pattern of the Hamilton basin
No full textThe Holocene history of the Hamilton basin and development of the soil pattern are closely related. The basin was partly filled by the large alluvial fan of the Waikato River which partly buried a hilly, ash-covered landscape. The normal depositional pattern of fans is recognisable (apex of coarse sediments; middle part with ridges of coarse sediments and swales with fine sediments; toe of fine sediments) but has been modified by changing river courses during fan building. Each of these courses was flanked by levees which dammed valleys and embayments and blocked drainage to form lakes. The lakes were the sources of the present day peat bogs. The properties of the soils developed on the wide range of parent materials and landforms in the basin are summarised
Depolarization and decreased surface expression of K+ channels contribute to NSAID-inhibition of intestinal restitution
No full textNon-steroidal anti-inflammatory drugs (NSAIDs) contribute to gastrointestinal ulcer formation by inhibiting epithelial cell migration and mucosal restitution; however, the drug-affected signaling pathways are poorly defined. We investigated whether NSAID inhibition of intestinal epithelial migration is associated with depletion of intracellular polyamines, depolarization of membrane potential (Em) and altered surface expression of K+ channels. Epithelial cell migration in response to the wounding of confluent IEC-6 and IEC-Cdx2 monolayers was reduced by indomethacin (100μM), phenylbutazone (100μM) and NS-398 (100μM) but not by SC-560 (1μM). NSAID-inhibition of intestinal cell migration was not associated with depletion of intracellular polyamines. Treatment of IEC-6 and IEC-Cdx2 cells with indomethacin, phenylbutazone and NS-398 induced significant depolarization of Em, whereas treatment with SC-560 had no effect on Em. The Em of IEC-Cdx2 cells was: −38.5±1.8mV under control conditions; −35.9±1.6mV after treatment with SC-560; −18.8±1.2mV after treatment with indomethacin; and −23.7±1.4mV after treatment with NS-398. Whereas SC-560 had no significant effects on the total cellular expression of Kv1.4 channel protein, indomethacin and NS-398 decreased not only the total cellular expression of Kv1.4, but also the cell surface expression of both Kv1.4 and Kv1.6 channel subunits in IEC-Cdx2. Both Kv1.4 and Kv1.6 channel proteins were immunoprecipitated by Kv1.4 antibody from IEC-Cdx2 lysates, indicating that these subunits co-assemble to form heteromeric Kv channels. These results suggest that NSAID inhibition of epithelial cell migration is independent of polyamine-depletion, and is associated with depolarization of Em and decreased surface expression of heteromeric Kv1 channels.ID: S0006295207001931; M3: Article; Accession Number: S0006295207001931; Author: L.C.

L'usage du narratif dans le Testament de Joseph
No full text(Résumé de l'ouvrage) Seventeen innovative studies are collected in this volume which has been produced under the aegis of the Centre for Biblical Studies, University of Manchester, and L'Institut des sciences bibliques, Université de Lausanne. The majority of the studies engage with narrative through providing insightful working examples. Building on the many contributions of recent narratological research, for the most part the studies in this collection avoid the technical language of narratology as they present fresh insights at many levels. Some essays focus more on the implied author, some on the implied reader or hearer, and some on the way particular messages are constructed; some of the studies consider how author, message and reader are all interconnected. There are several creative proposals for refining genre definition, from law and wisdom to gospel and apocryphal writings. Some studies highlight the way in which narratives can contain ethical, religious, and cultural messages. Sensitivity to narrative is also shown by some contributors to expose in intruing ways the redactional processes behind the final form of texts. Students of narrative in the ancient world will find much to consider in this book, and others engaged with literary studies more generally will discover that scholars of the worlds of the Bible and Late Antiquity have much to offer them
