Submarine melting of tidewater glaciers is proposed as a trigger for their recent thinning, acceleration and retreat. We estimate spring submarine melt rates (SMRs) of Kangiata Nunaata Sermia in southwest Greenland, from 2012 to 2014, by examining changes in along-fjord freeboard and velocity of the seasonal floating ice tongue. Estimated SMRs vary spatially and temporally near the grounding line, with mean rates of 1.3 ± 0.6, 0.8 ± 0.3 and 1.0 ± 0.4 m d−1 across the tongue in 2012, 2013 and 2014, respectively. Higher melt rates correspond with locations of emerging subglacial plumes and terminus calving activity observed during the melt season using time-lapse camera imagery. Modelling of subglacial flow paths suggests a dynamic system capable of rapid re-routing of subglacial discharge both within and between melt seasons. Our results provide an empirically-derived link between the presence of subglacial discharge plumes and areas of high spring submarine melting and calving along glacier termini.
Atomistic simulation methods have been used to model the structure of the (1014) surfaces of calcite, dolomite, and magnesite under dry and wet conditions. The potential parameters for the carbonate and water species contain shell terms to model the polarizability of the oxygen atoms. These static calculations show that the surfaces undergo relaxation leading to the rotation and distortion of the carbonate groups with associated movement of cations. The dry surface energies are 0.322, 0.247, and 0.256 Jm−2 for calcite, dolomite, and magnesite respectively. The influence of water on the surface structure and energies has been investigated for monolayer coverage. When fully hydrated with a monolayer of water, the surface energy for calcite is reduced indicating a stabilization of the surface with hydration. The extent of carbonate group distortion is greater for the dry surfaces compared to the hydrated surfaces, and for the dry calcite relative to that for dry magnesite.
Klaus Alpers has recently recovered from the obscurity of Byzantine lexica the fragments of what appears to be a novel dating from c. A.D. 100, and notable to us, as it was for the Byzantine excerptor, for the elegant verbal borrowings from ancient comedy, always a favourite source of good Attic Greek for the atticists of imperial times. One of these glosses gives occasion to look again at fishing metaphors for erotic business, a subject discussed often enough by scholars, but still perhaps capable of revealing new nuances. These hunting and fishing metaphors are used as one would expect in many non-amatory contexts, but in both love poetry and its allied genres they occur throughout antiquity in such quantity that the metaphorical complexity reaches into very allusive language. Long ago Preston had already pointed out that ‘Figures from hunting, fowling and fishing as parallel to the arts of the meretrix, are very frequent, and are developed at unusual length.’ There was undoubtedly a realistic side to all of this metaphorical hunting. ‘The lover is a fish to be baked, as long he has juice in him’, says the bawd at Plautus, Asinaria 177, and one needs little imagination to realize what plays can be made on such a theme, and indeed were made at all levels throughout antiquity.
J. Wackernagel and E. Löfstedt have both drawn attention to Pindar's ‘Neigung, das Futurum zu setzen bei Verben, die eine jetzt vorhandene, aber auf zukünftiges Tun abzielende Willensrichtung ausdrücken’. But they regarded this as a purely grammatical phenomenon, and did not note that the Pindaric use is practically limited to statements of the type, ‘I shall sing, glorify, testify, etc.’. It was E. Bundy who first drew attention to the conventional nature of these futures and so ended years of misunderstanding. So, for example, Wilamowitz considered that P. 1.75 represented an optative with while Slotty, following Breyer, thought that N. 9. 10 was an aorist subjunctive ‘auf Grund des pindarischen Sprachgebrauches’! Postgate, following Gildersleeve, thought that 0. 8. 57 represented though the contrary would appear to be more true, cf. 0. 13. 11: and also Hoekstra sees in the future ‘den Nebenbegriff des Konnens’.
Dodder (Cuscuta spp.) seedlings were killed when exposed to isopropyl m-chlorocarbanilate (chlorpropham) vapors in an enclosed system or in the open atmosphere in the greenhouse or field. No seedlings wrapped on the host when they were exposed for 16 hr or more in an enclosed system. Alfalfa (Medicago sativa L.) foliage restricted air movement near the treated soil and favored accumulation of vapors that killed emerged and emerging seedlings.
1. A pilot survey was designed to provide information on the mechanical conditions and fuel consumptions of vaporizing oil tractors, on their operation in the field and on the technique required to obtain such data.
2. Two areas were chosen offering a contrast in soil and farming types. A sampling frame was prepared for each area in which the farms were grouped according to the number of tractors.
The most important contribution the psychiatrist could make to the selection of officer candidates or of applicants for comparable leading or managerial positions would be the exclusion of potential neurotics. The Report on the Work of Psychologists and Psychiatrists in the services acknowledges and commends the contribution made by psychiatrists to the selection of officers in the Army; but evidence has not yet been published to enable the extent of their particular contribution to the efficiency of the whole procedure to be assessed in measured terms. Other services have not followed the example of the Army. The Admiralty and Civil Service Selection Boards, which were created after the War Office Selection Boards, and have adapted many features of the Army procedure for their own requirements, have decided against employing psychiatrists for this purpose; and the extent to which the War Office Selection Boards make use of psychiatric services for selection has been reduced. The effectiveness of existing psychiatric methods for this kind of work may thus be felt still open to some doubt.
