The paper reports on the results of an exploratory study into the topical organisation and stylistic features of argumentation in a corpus of ophthalmic clinical research papers. The study responds to the need for systematised and generalisable argumentation models in knowledgeintensive fields. We present here a schematised superstructure of the arguments from the corpus, charting the configura...

Divalent ions of the first series transition elements and Hg were introduced into a cadmium hydroxyapatite Cd5 (P04) 30H by replacing a part of Cd2+, and the effects on the crystal growths and the structural changes were studied. Cd2+ can be exchanged with Mn2+ up to about 30 mol %, with N¡Z+or Hg2+ up to about 10 mol %, and with a little amount of Fe2+ or Cu2+. It was found that Cd5 (PO.)sOH f...

The asset management and Life Cycle Costing (LCC) principals perform a vital role in the reduction and optimization of the costs of an infrastructure manager, providing a better decision support technically and financially. It was intended to create an asset management LCC model to rail track superstructure of the Portuguese rail network assembled with the Iberian gauge. This model is able to r...

This paper introduces a novel MILP approach for the design of distillation columns sequences of zeotropic mixtures explicitly including from conventional to fully thermally coupled sequences and divided wall columns with a single wall. The model is based on the use of two superstructure levels. In the upper level a superstructure that includes all the basic sequences of separation tasks and all...

The inclusion compound of urea with hexadecane has a superstructure of an ideal hexagonal structure found in other members of the series of urea-n-paraffin adducts consisting essentially of honeycomb-like channels formed by the host into which the long chain molecules are embedded. In order to elucidate the nature of the superstructure, which manifests itself by addiditonal weaker reflexions ( ...

Abstract During a systematic study on formation conditions of new compounds with zemannite-type structures, crystals ten oxidotellurate(IV) phases were grown under hydrothermal conditions, partially by employing drastic reduction the water content. The crystal structures obtained determined single-crystal X-ray diffraction. Na 2 [Ni (TeO 3 ) ]·2.5H O, K ]·H [Zn ]·2H Rb 1.25 [Co ]·1.5H O and 1.2...

Construction of a rose-like hierarchical superstructure composed of rare-earth hydroxide nanosheets and polyoxomolybdates, which was achieved by the self-assembly at room temperature, led to a drastically enhanced photoluminescence.

OBJECTIVES/HYPOTHESIS To review surgical findings and hearing outcomes of incus footplate assembly (IFA) for the patients with conductive hearing loss due to missing stapes superstructure with a mobile stapes footplate. STUDY DESIGN Retrospective case review and survey. METHODS Pre- and postoperative audiometric data and intraoperative findings were reviewed. Postoperative air-bone gap (ABG...

background change theories provide an opportunity for organizational managers to plan, monitor and evaluate changes using a framework which enable them, among others, to show a fast response to environmental fluctuations and to predict the changing patterns of individuals and technology. the current study aimed to explore whether the change in the public accounting system of the iranian health ...

Some stimuli are perceived as unitary patterns, and others as dual or plural patterns. Such 'unity-and-variety' phenomena are explained by various process approaches of perception, such as the global precedence hypothesis, the preattentive orientation detection assumption, and the recognition-by-components model. However, these three approaches, which will be discussed in this paper, each expla...
