“The Fifteen Signs of Doomsday of the First Riustring Manuscript”,
No full textIl saggio offre una disamina dettagliata – corredata di traduzione inglese – della versione frisone antica dei Quindici segni premonitori del Giudizio Universale, tramandata nel cosiddetto Primo Manoscritto Riustring (noto anche come ‘Asega-Book’), con particolare attenzione per l’individuazione delle fonti latine e dei paralleli in area germanica. Lo studio del testo frisone sui Quindici segni del Giudizio – uno dei rari documenti letterari in lingua frisone antica (il cui corpus è per lo più rappresentato da testi giuridici) – si focalizza sugli aspetti tematici e stilistici e sui topoi impiegati, identificando una precisa connessione ideologica tra i motivi escatologici dell’opera e il contesto (sostanzialmente giuridico) del manoscritto che lo conserva

Studies oor die toeganklike sinkstatus van sekere Vaalhartsgronde
No full textTen einde 'n volledige beeld van die toeganklike sinkstatus van gronde
van die Vaalhartsbesproeiingskema te verkry, is 36 veldproewe by verskillende
boere op die skema uitgele. 'n Ewekansige blokontwerp is in alle gevalle
gebruik. Die hoeveelheid sink wat met 0,1 N HCl, met E.D.T.A. en met ditisoon
geëkstraheer kan word, is vir al die grondmonsters bepaal en met die plantparameters:sinkkonsentrasie in die plant op pypstadium, plantmassa op pypstadium,
sinkopname tot op pypstadium en oesmassa in al die kontrole-persele
gekorreleer.
Uit hierdie gegewens kon kritiese grenswaardes vir die ektraksie-metodes
sowel as vir die plantparameters vasgestel word, wat van groot praktiese belang is. Op grond van praktiese bruikbaarheid en eenvoud kan die E.D.T.A.-
en HCl-metodes bo die'ditisoon-metode aanbeveel word, terwyl-met die E.D.T.A.-
metode ‘n effense meer betroubare voorspelling van verwagte oesmassa gegee kan word.
Geen reaksie in die oesmassa kon met sinktoediening verkry word nie, hoewel
daar aansienlike reaksie in plantmassa en sinkopname te bespeur was. Dit
is ook duidelik dat die vegetatiewe groei van koring van die sinkkonsentrasie
in die grond afhanklik is maar dat die reproduktiewe groei geensins deur die
sinkkonsentrasie in die grond beïnvloed word nie.
Dit het ook geblyk dat van die drie sinkkunsmisstowwe wat uitgetoets is,
sinkbemestingstof die swakste gevaar het. Sinkoksied het deurgaans beter gevaar,
terwyl sinksulfaat reeds by die laagste peil van toediening goeie reaksie
gegee het en teen hoër tóedienings swakker reaksie, waarskynlik as gevolg van
toksiteite
The nutrient status of two soil forms of the Orange River development project
No full textMainly two types of soil viz. the red sandy soils (Hutton form) and the yellow sandy soils (Clovelly form) were recommended by Van Rooyen (1965, 1967) for irrigational purposes under the Orange River Development Project. Fifteen soil profiles, comprising these two soil forms, were analysed for calcium, magnesium, potassium, sodium, phosphorus, sulphur, copper, zinc and manganese. A pot experiment, including a representative sample from each soil form and different levels of potassium and phosphorus, was conducted to test the reactions of these soils to phosphorus and potassium applications. Phosphate potential studies were conducted on selected samples from each soil form. These soils were found to be deficient in phosphorus, potassium, copper and zinc. A difference in the reaction of these soils to applied phosphorus and potassium was indicated. An extremely interesting relationship between the resin-P-content and phosphate potentials of these. soils was found
Of Angles and angels
No full textFrom a period of a thousand years from the first century AD to the eleventh, diverse sources in multiple languages collectively testify to the source and development of the group-name (‘ethnonym’) from which the familiar Angeln, Angles, England and English of modern usage derive. The complex range of early attested forms proves consistent with well-attested principles of language-use and language-change. Like any natural phenomenon, a group with an expressed and named identity will be a state of constant adaptation to circumstances, be those opportunities or stresses, and the adoption and replacement of the variants in textual history likewise conforms with historical circumstances in readily explicable ways. A comprehensive and empirically precise approach is especially important in case of the evolution from the Anglii to the English, which is of clear historical salience, and has attracted much inaccuracy and even misrepresentation
'How warped the mirrors': postmodernism and historiography
Get PDFPostmodernism, though it may be described in many ways, may be thought essentially to be captured by Lyotard's phrase, 'incredulity towards metanarratives'. The first chapter of my thesis attempts to define both 'postmodernism' and 'historiography', and then surveys historiographical discourse today. Because it is often ancient history that most frequently may be open to radically differing interpretations, I take in chapter two a 'generative' example, namely the speech compositions of Thucydides. This example I consider as 'generative' in the sense that it opens up questions, not only about the History of Thucydides itself and about how Thucydides is conceived in the ancient historiographical tradition, but also about what it means for an historian to disclose the 'truth' of an historical situation. My third chapter takes up the suggestion by Keith Jenkins that postmodern philosophy, particularly the conception of 'truth' and 'knowledge' proffered by Rorty, is a good way for history to acclimatise itself in the postmodern era. I survey Jenkins' proposals, and then discuss a work Jenkins largely ignores, i.e. Rorty's Philosophy and the Mirror of Nature. I demonstrate not just the familiar point that Rorty attempts to overturn 'foundationalist epistemology', and proposes 'new vocabularies' that involve 'hermeneutics' which set up I discourse as 'conversation'. This overturning involves for Rorty an assertion of 'unarbitrability', i.e. that it is impossible to argue that one view is better or more true than another. Thus Jenkins wishes to enter a world of a plurality of interpretations. In chapter four, however, I draw upon the work of Charles Taylor who argues for the necessity of 'arbitrage' in human discourse, whilst still wishing to overturn epistemological foundationalism. I therefore wish to advocate in my fifth chapter a 'third way', drawing on Taylor's theory of interpretation that requires neither a correspondence theory of truth, nor unarbitrability. Throughout the chapter I demonstrate how my conclusions regarding Thucydidean speeches and my discussion of postmodern philosophy may serve as a way of thinking about the task of historians, and hot just ancient historians. I conclude with some theological reflections on the arguments offered
Ghrelin selectively reduces mechanosensitivity of upper gastrointestinal vagal afferents
No full textCopyright © 2007 by the American Physiological SocietyGhrelin is a peptide released from gastric endocrine cells that has an orexigenic effect via a vagal pathway. Here we determine the effect of ghrelin on mechanosensitivity of upper-intestinal vagal afferent fibers in ferret and mouse. The responses of gastroesophageal vagal afferents to graded mechanical stimulation were determined in vitro before and during application of ghrelin to their peripheral endings. Three types of vagal afferent were tested: tension receptors responding to circumferential tension, mucosal receptors responding only to mucosal stroking, and tension/mucosal (TM) receptors in ferret esophagus that responded to both stimuli. In the mouse, ghrelin did not significantly affect the response of mucosal receptors to mucosal stroking with calibrated von Frey hairs. However, it significantly reduced responses of tension receptors to circumferential tension (P < 0.005; two-way ANOVA) by up to 40%. This inhibition was reversed by the ghrelin receptor antagonist [d-Lys-3]-growth hormone-releasing peptide (GHRP)-6. In the ferret, ghrelin significantly reduced the response of mucosal and TM receptors to mucosal stroking with calibrated von Frey hairs. Surprisingly, ghrelin did not significantly alter the response to circumferential tension in either tension or TM receptors. RT-PCR analysis indicated that both ghrelin and its receptor are expressed in vagal afferent cell bodies in mouse nodose ganglia. In conclusion, ghrelin selectively inhibits subpopulations of mechanically sensitive gastroesophageal vagal afferents; there is also potential for ghrelin release from vagal afferents. However, the subpopulation of afferents inhibited differs between species. These data have broad implications for ghrelin's role in food intake regulation and reflex control of gastrointestinal function.Amanda J. Page, James A.

Exercise as an intervention to improve metabolic outcomes after intrauterine growth restriction
No full textIndividuals born after intrauterine growth restriction (IUGR) are at an increased risk of developing diabetes in their adult life. IUGR impairs β-cell function and reduces β-cell mass, thereby diminishing insulin secretion. IUGR also induces insulin resistance, with impaired insulin signaling in muscle in adult humans who were small for gestational age (SGA) and in rodent models of IUGR. There is epidemiological evidence in humans that exercise in adults can reduce the risk of metabolic disease following IUGR. However, it is not clear whether adult IUGR individuals benefit to the same extent from exercise as do normal-birth-weight individuals, as our rat studies suggest less of a benefit in those born IUGR. Importantly, however, there is some evidence from studies in rats that exercise in early life might be able to reverse or reprogram the long-term metabolic effects of IUGR. Studies are needed to address gaps in current knowledge, including determining the mechanisms involved in the reprogramming effects of early exercise in rats, whether exercise early in life or in adulthood has similar beneficial metabolic effects in larger animal models in which insulin resistance develops after IUGR. Human studies are also needed to determine whether exercise training improves insulin secretion and insulin sensitivity to the same extent in IUGR adults as in control populations. Such investigations will have implications for customizing the recommended level and timing of exercise to improve metabolic health after IUGR.Kathryn L.

Latin brutes, sapo, burdo
Get PDFThe Germanic languages have adopted many words borrowed from Latin during the time of the Roman Empire (e.g. ModE wine, NHG Mauer < Latin vīnum, mūrus ‘wall’). The medieval Germanic languages, on the other hand, le their traces in Romance during the time Germanic peoples settled on former Roman territory (e.g. Fr. guerre, salle < Franc. *werra ‘quarrel’, *sali- ‘hall, house’). Yet, there is a third and older group of words which are quoted in Latin literature and inscriptions long before the Roman Empire came to an end and individual Romance languages emerged. Well known examples are glaesum ‘amber’ and ūrus ‘aurochs’. Some of these words became established as loanwords in Latin, while the status of others is less clear. My paper focuses on three examples from this group — brutes, sapo and burdo – and the methodological and analytical implications connected to their investigation. The main questions are if and how a Germanic origin can be substantiated and what kinds of processes might have been involved
Data for Determination of band offsets, hybridization and exciton binding in 2D semiconductor heterostructures
Get PDFCombining monolayers of different two-dimensional semiconductors into heterostructures creates new phenomena and device possibilities. Understanding and exploiting these phenomena hinge on knowing the electronic structure and the properties of interlayer excitations. We determine the key unknown parameters in MoSe2/WSe2 heterobilayers by using rational device design and submicrometer angle-resolved photoemission spectroscopy (μ-ARPES) in combination with photoluminescence. We find that the bands in the K-point valleys are weakly hybridized, with a valence band offset of 300 meV, implying type II band alignment. We deduce that the binding energy of interlayer excitons is more than 200 meV, an order of magnitude higher than that in analogous GaAs structures. Hybridization strongly modifies the bands at Γ, but the valence band edge remains at the K points. We also find that the spectrum of a rotationally aligned heterobilayer reflects a mixture of commensurate and incommensurate domains. These results directly answer many outstanding questions about the electronic nature of MoSe2/WSe2 heterobilayers and demonstrate a practical approach for high spectral resolution in ARPES of device-scale structures
