    Get PDF
    This document provides an overview of the facts and disposition of federal cases interpreting whether vessels are “public vessels” under U.S. admiralty law. This document is a supplement to Status of the U.S. Academic Research Fleet as Public Vessels under U.S. and International Law, which discusses these cases and other legal authorities relevant to a determination of whether U.S. academic research fleet vessels are public vessels. The cases in this document are arranged by circuit and type of court and are presented in reverse chronological order within each court. This document is to be used for research purposes only and is not legal advice

    A framework of distributed sensemaking in investigations

    Get PDF
    This paper reports the work involved in the development of the distributed sensemaking framework. The framework serves as a mechanism to describe the appropriation of elements of the distributed cognitive system in support of sensemaking in investigatory activities. Here we outline the work leading to the formulation of the distributed sensemaking framework and implications for the design of new technologies

    A Kosloff/Basal method, 3D migration program implemented on the CYBER 205 supercomputer

    Get PDF
    Conventional finite difference migration has relied on approximations to the acoustic wave equation which allow energy to propagate only downwards. Although generally reliable, such approaches usually do not yield an accurate migration for geological structures with strong lateral velocity variations or with steeply dipping reflectors. An earlier study by D. Kosloff and E. Baysal (Migration with the Full Acoustic Wave Equation) examined an alternative approach based on the full acoustic wave equation. The 2D, Fourier type algorithm which was developed was tested by Kosloff and Baysal against synthetic data and against physical model data. The results indicated that such a scheme gives accurate migration for complicated structures. This paper describes the development and testing of a vectorized, 3D migration program for the CYBER 205 using the Kosloff/Baysal method. The program can accept as many as 65,536 zero offset (stacked) traces

    Ancient Wheat Species Can Extend Biodiversity of Cultivated Crops

    Wheat genetic resources may be grown in organic farming systems or in less favourable areas for bread wheat species. Characteristics of hulled wheat species (23 varieties of einkorn, emmer wheat, spelt wheat) were studied and evaluated within a two-year trial period (which was executed on certified organic fields) and they were compared to characteristics of landraces and modern bread wheat varieties. The main aim of our study was to evaluate the potential uses of genetic resources of wheat in organic farming. The hulled wheat species were resistant to mildew and brown rust. Their grains were less contaminated with DON than the grains of the control varieties. The grain yield rate was reduced. Per hectare crude protein yield was higher in spelt and emmer wheat species than in the control varieties. High protein proportion in grain was an important advantage of the hulled wheat species. Spelt wheat is suitable for production of products similar to bread wheat (they have similar technological qualities). Einkorn and emmer wheat contain worse-quality gluten and therefore are suitable for the production of unyeasty products, that is pasta, mush, traditional unyeasty bread, etc

    Winter wheat roots grow twice as deep as spring wheat roots, is this important for N uptake and N leaching losses?

    Cropping systems comprising winter catch crops followed by spring wheat could reduce N leaching risks compared to traditional winter wheat systems in humid climates. We studied the soil mineral N (Ninorg) and root growth of winter- and spring wheat to 2.5 m depth during three years. Root depth of winter wheat (2.2 m) was twice that of spring wheat, and this was related to much lower amounts of Ninorg in the 1 to 2.5 m layer after winter wheat (81 kg Ninorg ha-1 less). When growing winter catch crops before spring wheat, N content in the 1 to 2.5 m layer after spring wheat was not different from that after winter wheat. The results suggest that by virtue of its deep rooting, winter wheat may not lead to high levels of leaching as it is often assumed in humid climates. Deep soil and root measurements (below 1 m) in this experiment were essential to answer the questions we posed

    Differences in Yield Parameters of Emmer in Comparison with Old and New Varieties of Bread Wheat

    Emmer wheat (Triticum diccocum Schrank) belonged to the most frequent species of cereals in the past. Nowadays, it is grown in arid and montane areas in particular. Interest in this cereal species has increased, as it is tolerant to biotic and abiotic stressing factors. Therefore, yield parameters were evaluated in three-year (2007, 2008 and 2010) trials that were carried out in two different localities in the Czech Republic. Results of the research were compared to characteristics of four old and two top modern bread wheat (Triticum aestivum L.) cultivars. The emmer wheat varieties were resistant to usual wheat diseases. They formed their yield by a quantity of productive tillers (2.5), whereas the varieties of bread wheat had less productive tillers (1.5) per one plant. The distribution of assimilates was worse in the emmer wheat plants and it provoked a lower harvest index (0.33) there. Grain yield of the emmer wheat varieties reached 58% of the yield level of the mean of control bread wheat varieties. High crude protein content in grain (17.91%) was an advantage of the emmer wheat varieties; the control bread wheat varieties reached 13.73%. Protein content was positively influenced (P < 0.01) by an ability of the emmer varieties to uptake as much nitrogen as possible from the soil during the flowering period. Adaptability to the land and climatic environmental conditions was another positive characteristic of the emmer wheat landraces in comparison with old and modern bread wheat varieties

    Proportion of common wheat kernels in commercial samples of durum wheat by chemical methods

    Full text link
    Durum wheat (Triticum durum Desf.) is used for production of semolina which is the required raw material for the elaboration of good quality pasta products. Common wheat (T. aestivum L,)t generally used in breadmaking, yields milling products (flour or fariña) that are not suitable for that purpose. Shortage and localization of durum wheat production, as well as its higher cost, have compelled the utilization of common wheat for the production of macaroni. When different blends of hérd or soft wheat (fariña or flour) with durum wheat are used, the quality of macaroni is reduced. Por this reason, the estimation of common wheat in pasta products is an important problem from the point of view of quality and market control, Chemical methods for detection and estimation of common wheat in pasta products have been developed in this laboratory during the past six years. The related problem of estimating the proportion of common wheat kernels in commercial samples of durum wheat has been traditionally solved either by niorphológica1 examination or by cytogenetical methods. The former are too unreliable and the latter too cumbersome, In this paper, we have reviewed the above mentioned chemical methods and investigated their application to the analysis of single kernels and the estimation of the proportion of common wheat kernels in commercial samples of durum wheat in order to avoid the cytogenetical methods or to confirm the morphological examination
