    Collaborations: the architecture of Ahrends, Burton and Koralek (ABK) edited by Kenneth Powell

    No full text
    English: This article on one of the enduring British partnerships is not a vanity publication that we are accustomed to in our profession. Edited by Kenneth Powell, it contains illuminating essays of overlapping themes. The editor provides the overview. Jeremy Melvin writes a sensitive piece on the formation of the practice. While Elain Harwood and Frank Macdonald respectively describe early works and Irish projects of the practice Paul Finch contributes an intelligent essay on collaboration. The essays are not presented in succession but in layered colour strips on the top and bottom of pages with images in the body under the thematic titles of private/public, context, light/space and process. One does have to overcome the initial irritation of this unconventional layout before realising the importance of the ABK story. Indeed the interlocking of different narratives and the images has a resonance with the character of the practice itself, with three distinct personalities of Ahrends, Burton and Koralek, each with unique but complementary interests and predilections.Afrikaans: Hierdie artikel oor een van die langdurigste Britse vennootskappe, is nie ’n waardelose publikasie soos waaraan die professie gewoond is nie. Soos deur Kenneth Powell geredigeer, bevat dit verligte essays met oorvleulende temas. Die redigeerder verskaf ’n oorsig. Jeremy Melvin skryf ’n sensitiewe essay oor die vorming van die praktyk, terwyl Elain Harwoord en Frank Macdonald wedersyds die eerste werke en Ierse projekte van die praktyk beskryf. Paul Finch se bydrae is ’n intelligente skrywe oor samewerking. Die essayss word nie opeenvolgende aangebied nie, maar in lae gekleure stroke op die bo- en onderkant van bladsye met grafieke in die teks ingedeel onder die titels: privaat/publiek, konteks, lig/ruimte en proses. ’n Mens moet aanvanklik die irritasie rondom hierdie manier van uiteensetting oorkom om die belangrikheid van die ABK storie te besef.Publisher's versio

    Tuning stability of titania-supported Fischer-Tropsch catalysts: Impact of surface area and noble metal promotion

    No full text
    Cobalt oxidation is a relevant deactivation pathway of titania-supported cobalt catalysts used in Fischer-Tropsch synthesis (FTS). To work towards more stable catalysts, we studied the effect of the surface area of the titania support and noble metal promotion on cobalt oxidation under simulated high conversion conditions. Mössbauer spectroscopy was used to follow the evolution of cobalt during reduction and FTS operation as a function of the steam pressure. The reduction of the oxidic cobalt precursor becomes more difficult due to stronger metal-support interactions when the titania surface area is increased. The reducibility was so low for cobalt on GP350 titania (surface area 283 m2/g) that the catalytical activity was negligible. Although cobalt was more difficult to reduce on P90 titania (94 m2/g) than on commonly used P25 titania (50 m2/g), the Co/P90 catalyst showed increased resistance against cobalt sintering and higher FTS performance than Co/P25. The addition of platinum to Co/P90 led to a higher reduction degree of cobalt and a higher cobalt dispersion, representing a catalyst with promising performance at relatively low steam pressure. Nevertheless, the stronger cobalt-titania interactions result in more extensive deactivation at high steam pressure due to oxidation.RST/Fundamental Aspects of Materials and EnergyRID/TS/Instrumenten groe

    The dagger

    No full text
    In the 22nd century cal BC (Figure 4.33 First Dig: Cist 2205–2130 cal BC (68% probability)) a dramatic alteration of the Henge 1 interior occurred. A large pit was dug into the partially filled henge ditch in the southern interior of the enclosure within a fewmetres of where the cremation cemetery had been established almost a millennium previously. Within this pit, large sandstone slabs were arranged to form a cist, in which was placed a rich burial with a rangeof grav e goods including a dagger in its sheath. The grave was then sealed beneath a massive capstone,and finally a cairn was raised over the cist. The uselife of Henge 1 did not end with the insertion of this burial; further activity is evident in the 1st millennium AD and modern period. However, the insertion of the cist appears to have marked the beginning of the end of the prehistoric phase of significance at Forteviot identifiable in the archaeological record

    The poetics of being

    No full text
    The aim of The Poetics of Being is to inquire into how the apperception of the Being of beings is produced. We will recognize this production not primarily in philosophy, but in a medium accessible to us all, theatre. Although the Romantic tradition of literary criticism from Herder to Bloom has noted that Shakespeare produces an exceptional sense of what is [true], so much so that he is said to create the impression of nature or life, no one has so far attempted to show how precisely Shakespeare affects this experience. Contrary to T. S. Eliot, who is unable to discern any kind of poetics in Shakespeare's plays, we have discovered an insistent and consistent pattern of inadequation, a kind of mismatch. The thesis argues, that the predominant tropes of inadequation are falsity, dissimilarity, nothing, indefinition, elision and substitution. We shall show that these figures of inadequation are the universal means by which Shakespeare, almost imperceptibly, compels the spectator to infer the apperception of what is [true]. On the basis of these tropes of inadequation the thesis makes the fundamental philosophical claim that the cognition of Being through non-Being is a negative form of what Heidegger calls the ontological difference. We call this the negative ontological difference. The thesis demonstrates that with the exception of some Pre-Socratic thinkers, Plato in the Sophist, the work of Pseudo-Dionysius, and the writings of Derrida, the bulk of the tradition of Western philosophy has argued Being in terms of positivities. While the thesis does not question the possibility of realizing the ontological difference in a positive fashion, as does Heidegger's philosophy of unconcealment, the thesis claims that the negative ontological difference, or ontological contradiction, is the more forceful process by which we become aware of what is [true]

    (Appendix A) Helium isotope concentrations and ratios for leached replicates of sediments from ODP Hole 130-806B

    To maximize the size of the samples analyzed, aliquots of 2 to 3 g were leached in 10% acetic acid for 6 h to remove CaCO3. This resulted in residues of about 250 mg of noncarbonate material, which were suitable for handling in the gas extraction system. Samples were then rinsed in distilled water, centrifuged to isolate the residue, ovendried at 60°C overnight, and wrapped in tin foil ready for loading into the Caltech Noble Gas Laboratory all-metal gas extraction system. Comparison between 2 to 3 g leached and 0.5 g unleached (bulk) aliquots of the same sample shows that helium in the samples is not affected by acetic acid leaching

    Complex systems modeling for supply and demand in health and social care

    No full text
    This paper introduces a major new cross-disciplinary research project that looks at the UK health and social care system, as part of an ambitious, broader initiative to apply methods from complexity science to a range of key global challenges. This particular project aims to develop new, integrated models for the supply and demand of both health and social care, in the context of the societal change brought about by migration, mobility and the ageing population. We discuss the background to the work, and the broad way in which we intend to leverage complexity science. This is made more specific with a brief discussion on existing demographic models, and some examples of model-building in progress. We conclude with a glimpse into the subtly difficult problems of fostering such innovative interdisciplinarity

    Reverse osmosis as a method for removing ethyl carbamate from model wine solutions

    No full text
    Ethyl carbamate is a carcinogenic compound that can be found in all fermented products, including wine and other alcoholic beverages. A method for its removal or reduction is necessary. Eleven model wine solutions consisting of ethanol at 12-14% v/v and any or all of the following were made: glycerol at 4g/L, glucose at 2 g/L, tartaric acid at4 g/L, malic acid at 4 g/L, and ethyl carbamate (urethane)at 37-39 ppb. The model solutions were pumped in a single pass through a Millipore 200 nominal molecular weight cutoff (nmwc) reverse osmosis (ro) membrane at 300-250 psi. Retentates and permeates were collected. The feed, permeate, and retentate for each run were analyzed for pH, ethanol, extract, and titrable acidity (TA). Urethaneanalyses were performed by gc-ms for the final six runs. The results of the study failed to show a significant reduction of urethane levels in the model wine solutions used; thus, the final results of the study wereinconclusive
