    “P O T A T O E S are an important food in Alaska. Matanuska V alley farmers can produce enough to meet the needs of the Anchorage area if the crop can be kept satisfactorily from one year to the next. The Alaska climate, however, makes better-than-average storage and management necessary to insure a continuous supply throughout the year.Custom storage -- Storage pit -- House-basement storage -- Earth-covered storage -- Sawdust-covered storage -- Frame storage with shell circulation -- Round-roofed storages -- Matanuska Experiment Station storag

    Acknowledging debt in Medieval England: a study of the records of Medieval Anglo-Jewish moneylending activities 1194-1276

    Get PDF
    This thesis examines a collection of 348 acknowledgements of debt, which were generated by Jewish moneylending activities between 1194 and 1275/6. It considers the legal and administrative structures within which they were produced, before analysing the transactions which they record. In particular, it follows the models which have been established for the analysis of Christian charters and applies them to what have traditionally been regarded as ‘Jewish documents’. Significantly, this thesis moves away from traditional narratives, which situate such records in the context of royal document production, to consider more fully the relationship between the Jews and the civic communities with which they lived and interacted. As a result, this study challenges traditional approaches to medieval Anglo-Jewish sources (which distinguish between the records of Church and State). This makes it possible to distinguish between the role of local, regional, and national influences on document production. Equally, the size of the corpus, which spans most of the thirteenth century, makes it possible to move away from generalised discussions which span the period under consideration to, instead, comment precisely on when and how developments occurred

    From archae to archives

    Acknowledgments of debt, made to the Jews of England between 1194 and 1290, have long been known to historians. The two largest collections of acknowledgements, stored in the Westminster Abbey Muniments and The National Archives, have been utilised in very different ways. There is no substantive difference in the nature of the records themselves and, as such, it is to the archival history of these documents that one must look in order to account for that discrepancy. Thus, this paper is concerned with establishing the custodial history of the acknowledgements and determining the impact that this has had upon their use. Equally, it uses this later history in order to cast new light upon the origins of the documents

    Development of an image converter of radical design

    A long term investigation of thin film sensors, monolithic photo-field effect transistors, and epitaxially diffused phototransistors and photodiodes to meet requirements to produce acceptable all solid state, electronically scanned imaging system, led to the production of an advanced engineering model camera which employs a 200,000 element phototransistor array (organized in a matrix of 400 rows by 500 columns) to secure resolution comparable to commercial television. The full investigation is described for the period July 1962 through July 1972, and covers the following broad topics in detail: (1) sensor monoliths; (2) fabrication technology; (3) functional theory; (4) system methodology; and (5) deployment profile. A summary of the work and conclusions are given, along with extensive schematic diagrams of the final solid state imaging system product

    Triple point determinations of monomethylhydrazine and nitrogen tetroxide, 2.2 percent by weight nitric oxide

    Get PDF
    A series of tests was performed to ascertain the triple points of monomethylhydrazine and nitrogen tetroxide. A laboratory method indicated a triple point for monomethylhydrazine, but tests in a large vacuum chamber indicated that a triple point does not occur in spacelike conditions because the mono-methylhydrazine tends to supercool. Instead, an effective freezing point (with agitation) was obtained. New experimental values for liquid monomethylhydrazine vapor pressure were determined for temperatures from 275.2 to 207.6 K. The values were used to derive vapor pressure equations. Tentative values were obtained for the effective freezing point of nitrogen tetroxide spacelike conditions
