    Axial backmixing and residence time distribution in a miniaturized, stirred-pulsed extraction column (2017)
    Wiley
    Details
    Publication Date: 2017-11-16
    Description: Axial backmixing is an important issue in extraction columns, since it heavily affects mass transfer performance. A miniaturized, stirred-pulsed column was investigated regarding its backmixing characteristics in the continuous phase using the system water/n-butyl acetate. Residence time distributions were determined through pulse experiments with potassium chloride, which was detected via electrical conductivity. To perform the conductivity measurement without distortion of the two-phase flow, electrodes with an annular design were manufactured, which precisely line up with the inner column wall. This design is a promising alternative for using in small-scale tubular devices, where commercial electrodes do not fit, and in applications, where interference with the flow must be avoided.

    Childhood acute lymphoblastic leukemia with chromosomal breakpoints at 11q23 (1989)
    American Society of Hematology
    Details
    Publication Date: 1989-05-01
    Description: Twenty-one (5.7%) of 368 cases of acute lymphoblastic leukemia (ALL), studied fully for karyotype and immunophenotype, had breakpoints in the q23 region of chromosome 11. This abnormality resulted from reciprocal translocation in 17 cases [with chromosomes 4 (n = 5), 10 (n = 2), and variable chromosomes (n = 10)], from deletions in three cases, and from a duplication in one case. The 17 children with 11q23 translocations had higher leukocyte counts (P less than .01) and were more likely to be black (P less than .01) and younger (P = .08) as compared with each of the following non-11q23 translocation groups: t(1;19), t(9;22), random translocations, and cases without translocations. Event-free survival at 3 years for the 11q23 translocation group did not differ significantly from that of the t(1;19), t(9;22), or random translocation groups. Leukemic cells from ten of the 21 patients with an 11q23 structural chromosomal abnormality had an immunophenotype indicative of B-lineage ALL (HLA-DR+, CD19+, CD2-, CD3-); this was confirmed by the presence of rearranged immunoglobulin heavy-chain genes in seven cases. In eight of these ten B-lineage cases, the blasts were negative for expression of the CD10 antigen, indicating a primitive stage of B-cell development. Four cases were classified as T- cell ALL, and seven others were characterized by blasts that failed to react with our panel of lineage-associated monoclonal antibodies (MoAbs). Myeloid antigens were expressed by leukemic cells in three of the cases that were tested. The initial clinical features associated with translocations involving the 11q23 chromosomal region may define a distinct subtype of ALL. Whether the constellation of findings relates to a breakpoint at 11q23 per se or to the specific translocation will require further study.

    Notes: Abstract The response of corn (Zea mays L.) to broadcast P applications and to small amounts of fertilizer placed with the seed (fws) was measured in three field trials conducted for 10 years. Five rates of P (0, 11, 22, 45, and 90 kg ha−1 yr−1) were applied with and without 4.0-6.4-3.2 kg N, P, K ha−1 placed with the seed (fws) in a factorial arrangement of treatments. The fws treatment delayed emergence at all sites, reduced final emergence at two of the three sites, increased seedling dry weights at the 4 to 6 leaf stage and reduced the time to 50% silking at two of the three sites. Ear moisture content at harvest was reduced by fws at all sites which indicated that fws advanced maturity. The fws treatment increased grain yield at two of the sites by 1.3 and 2.3%, respectively. Broadcast P applications increased seedling dry weight at all sites but decreased the time to 50% silking only at one site. Broadcast P decreased ear moisture content and increased grain yield at two sites. There was a significant fws by broadcast P interaction in the most P deficient soil such that response to broadcast P was lessened by fws. The interaction was strongest during the early stages of growth and decreased with maturity resulting in no fws by broadcast P interaction for grain yield.

    Lake Søbygaard: a shallow lake in recovery after a reduction in phosphorus loading (1987)
    Springer
    GeoJournal 14 (1987), S. 381-384 
    Details

    Notes: Abstract The development and recovery of a shallow and hypertrophic lake following a reduction in the external phosphorus load has been documented. In spite of this reduction, phosphorus concentrations and phytoplankton biomass in the lake water are still very high. The reason for this development can be explained by three main factors: (1): the sediment has been accumulating a large phosphorus pool which is now causing a high internal phosphorus load, (2) due to the shallow conditions, resuspension of the upper sediment often takes place because of wind action and thereby increases the phosphorus loading from the sediment, (3) the development of a large population of planktivorous fish decreases the zooplankton biomass resulting in the development of a large phytoplankton biomass.

    Description / Table of Contents: Laminated coating systemsAfter the introductory discussion of the selection of suitable natural and synthetic textiles and of coating agents for the preparation of laminated coating systems (coats with fabric insertions), an illustrated survey of some magnitude is given of coating techniques for laminated coating system on metal surfaces. It is shown in detail that such coatings are much superior to normal coating in regard to freedom from defects, mechanical proporties, and protection against various aggressive liquids (mineral acids, solvents).
    Notes: Einleitenden Richtlinien für die Auswahl geeigneter natürlicher und synthetischer Textilien sowie Anstrichmittel zum Aufbau laminierter Anstrichsysteme (Anstriche mit Gewebeeinlage) folgt ein ausführlicher Abriß über die Technologie des Aufbringens laminierter Anstriche auf Metalloberflächen in Wort und Bild. Es wird in allen Einzelheiten gezeigt, daszlig; Fehlerfreiheit, mechanische Eigenschaften und der Schutzwert des Systems gegen verschiedene aggressive Flüssigkeiten (Mineralsäuren, Lösungsmittel) ungleich höher sind als bei einfachen Anstrichen.

    Microseismic Focal Mechanisms and Implications for Changes in Stress during the 2014 Newberry EGS Stimulation (2019)
    Seismological Society of America (SSA)
    Details
    Publication Date: 2019
    Description: 〈span〉〈div〉Abstract〈/div〉We adapt the relative polarity method from 〈a href="https://pubs.geoscienceworld.org/bssa#rf29"〉Shelly 〈span〉et al.〈/span〉 (2016)〈/a〉 to compute focal mechanisms for microearthquakes associated with the 2014 hydroshearing stimulation at the Newberry volcano geothermal site. We focus the analysis on events relocated by 〈a href="https://pubs.geoscienceworld.org/bssa#rf2"〉Aguiar and Myers (2018)〈/a〉, who report that six event clusters predominantly comprise the 2014 sequence. Data quality allows focal mechanism analysis for four of the six event clusters. We use 〈a href="https://pubs.geoscienceworld.org/bssa#rf13"〉Hardebeck and Shearer (2002〈/a〉, 〈a href="https://pubs.geoscienceworld.org/bssa#rf14"〉2003〈/a〉; hereafter HASH) to compute focal mechanisms based on first‐motion polarities and 〈span〉S〈/span〉/〈span〉P〈/span〉 amplitude ratios. We manually determine 〈span〉P〈/span〉‐ and 〈span〉S〈/span〉‐wave polarities for a well‐recorded reference event in each cluster, then use waveform cross correlation to determine whether recordings of other events in the cluster are the same or reversed polarity at each network station. Most waveform polarities are consistent with the affiliated reference event, indicating similar focal mechanisms within each cluster. The deeper clusters are east–west‐striking normal faults, whereas the shallower clusters, close to the top of the open‐hole section of the borehole, are strike slip with east–west motion. Regional studies and prestimulation borehole breakouts find the maximum stress direction is vertical and maximum horizontal stress is approximately north–south. Fault geometry and focal mechanisms of microseismicity during the stimulation suggest that increased pressure from fluid injection predominantly caused changes in horizontal stress, consistent with predictions from numerical studies of stress change caused by fluid injection. At shallow depths, where previous studies suggest the difference between vertical and horizontal stress is lowest, injection appears to have rotated the direction of maximum stress from vertical to horizontal, resulting in strike‐slip motion. At greater depth, vertical stress continued to be the dominant direction during the stimulation, but fault orientation indicates either reactivation of pre‐existing fractures or rotation of the direction of maximum horizontal stress from approximately north–south to east–west.〈/span〉
