    Endothenia oblongana in Nederland: een bladroller van het zeedorpenlandschap (Lepidoptera: Tortricidae) (1998)
    In:  Entomologische berichten vol. 58, 8, pp. 145-152
    Details
    Publication Date: 2024-01-12
    Description: The occurrence of Endothenia oblongana in The Netherlands is confirmed, both by the discovery of old material and by new records. Several specimens were collected in rich grasslands in the coastal dunes, near villages, characterised by extensive human activities and a rich vegetation, with a unique lepidopterous fauna. Data on morphology, biology and distribution of this species and the closely related E. gentianaeana and E. marginana are given.

    Molar tooth diversity, disparity, and ecology in Cenozoic ungulate radiations (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-11-29
    Description: A classic example of adaptive radiation is the diversification of Cenozoic ungulates into herbivore adaptive zones. Their taxonomic diversification has been associated with changes in molar tooth morphology. Analysis of molar crown types of the Artiodactyla, Perissodactyla, and archaic ungulates ("Condylarthra") shows that the diversity of genera and crown types was high in the Eocene. Post-Eocene molars of intermediate crown types are rare, and thus the ungulate fauna contained more taxa having fewer but more disparate crown types. Taxonomic diversity trends alone give incomplete descriptions of adaptive radiations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jernvall, J -- Hunter, J P -- Fortelius, M -- New York, N.Y. -- Science. 1996 Nov 29;274(5292):1489-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Biotechnology and Department of Ecology and Systematics, Post Office Box 56, 00014 University of Helsinki, Finland. at Stony Brook, Stony Brook, NY 11794-436.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8929401" target="_blank"〉PubMed〈/a〉

    Population growth and earth's human carrying capacity (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-07-21
    Description: Earth's capacity to support people is determined both by natural constraints and by human choices concerning economics, environment, culture (including values and politics), and demography. Human carrying capacity is therefore dynamic and uncertain. Human choice is not captured by ecological notions of carrying capacity that are appropriate for nonhuman populations. Simple mathematical models of the relation between human population growth and human carrying capacity can account for faster-than-exponential population growth followed by a slowing population growth rate, as observed in recent human history.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cohen, J E -- New York, N.Y. -- Science. 1995 Jul 21;269(5222):341-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Populations, Rockefeller University, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7618100" target="_blank"〉PubMed〈/a〉

    Produktion 2000 — Trying to jointly improve technology, organisation and qualification (1998)
    Springer
    AI & society 12 (1998), S. 21-28

    Notes: Abstract Produktion 2000 is a German federal framework programme which supports the development of technology, organisation and qualification for production in industry. The Programme was launched in 1995 in view of the urgent need for improvement felt by industry itself after a very careful analysis and definition phase. The Programme is managed by a special Agency on behalf of the Federal Ministry. Their staff offers support in defining, implementing, running and controlling collaborative industry-driven projects and by awarding financial grants to the project partners. Strategic projects and first results are reported.

    Restructuring food for corporate profit: The corporate genetics of Cargill and Monsanto (1999)

    Notes: Abstract It is important to talk about corporations as a class, about trade agreements, and about government policy; but without examining specific examples of how real corporations actually shape the world to suit their purposes, we stand little chance of understanding the determinative forces behind government policy and trade agreements, and even less chance of affecting them. This article uses the metaphor of “genetics” (inherent character) to examine two major transnational corporations operating at the extremes of restructuring life.

    α-Iminohydroxylamine-α-aminonitrone tautomerism: a 1∶1 mixture of two tautomeric forms in crystals of N-(4,5-dihydro-1H-imidazol-2-yl)-N-phenyl-hydroxylamine (1995)

    Notes: Abstract Crystals consisting of two distinct chemical entities, tautomers of each other, in exact 1∶1 ratio, have been obtained and their structure determined by X-ray analysis. The crystals of C9H11N3·C9H11N3 are monoclinic,P21/c,a=15.674(3),b=17.085(3),c=13.758(3)Å, β=90.78(2)°,Z=8. There are two hydroxylamine and two aminonitrone molecules in the asymmetric unit. Hydrogen bonds connect those molecules into chiral layers. Layers of opposite chirality alternate andthe crystal is centrosymmetric as a whole. Within those layers chains of tautomers joined by very strong O−H... O and strong N−H... N bonds can be recognized. Proton transfer along those chains with simultaneous rearrangement of π-bonds within the molecules would result in interconversion of tautomers and would affect chirality of the layer.

    Dialkylimidazolium-sodium chloroaluminate ternary salt system: phase diagram and crystal structure (1995)
    Springer
    Journal of chemical crystallography 25 (1995), S. 57-62

    Keywords: phase diagram ; buffered chloroaluminate ; crystal structure

    Notes: Abstract The phase diagram of the buffered neutral aluminum chloride + 1-ethyl-3-methyl-1H-imidazolium chloride + sodium chloride (AlCl3-EMIC-NaCl) ternary melt system can be represented by a binary phase diagram composed of (EMI)AlCl4 and NaAlCl4. In the binary phase diagram, the salts are liquid at, or near, room temperature for a wide range of compositions. At the 1∶1 composition, the congruently melting compound (EMI)(Na)(AlCl4)2 with m.p.=36.7°C is formed. Crystals of this mixed organic-inorganic salt were grown for single crystal x-ray diffraction analysis. The compound crystalizes in the space group $$P\bar 1$$ with lattice parametersa=10.321(1) Å,b=10.895(3) Å,c=9.284(4) Å, α=98.31(2)°, β=100.83(4)°, γ=101.95(3)°. Data collected at −120°C gave final residuals ofR=0.037 andR w=0.045 using 2713 observed reflections. The packing diagram reveals Na+ ion zig-zag chains running along thea-axis with each Na+ surrounded by four AlCl 4 − units, reminiscent of NaAlCl4. The AlCl 4 − ions form a distorted square planar coordination sphere around Na+ at an average Na−Al distance of 3.76(4) Å. Using a sodium ionic radius of 1.16 Å, a new AlCl 4 − ionic radius of 2.60 Å is calculated. This radius is 0.21 Å shorter than the reported thermodynamic radius.

    Notes: Abstract The crystal structure of Ca10K4(P2O7)6·9H2O has been determined by single crystal X-ray diffraction. Crystals are hexagonal, space group P63cm witha=11.761(1),c=9.770(1) Å, andZ=1. The structure was refined toR=0.028 andR w=0.037 for 468 reflections withI≥3σ(I). The structure consists of a compact assembly of Ca and P2O7 ions arranged in layers perpendicular to thec-axis in a hexagonal array with relatively large open channels along thec-axis. The K ions and the water molecules are located in these open channels and are disordered.
