No full textIn opdracht van de afdeling Openbare Werken van de gemeente Noordwijk heeft archeologisch onderzoeksbureau Becker & Van de Graaf bv een archeologisch onderzoek uitgevoerd ter plaatse van een toekomstig rioolretentiebassin op de hoek van de Van Panhuysstraat en de Duinweg in Noordwijk, gemeente Noordwijk. Het onderzoek bestond uit een archeologische opgraving die is uitgevoerd van 1 oktober tot en met 8 november 2007. De aanleg voor dit onderzoek is de geplande bouw van een rioolretentiebassin. Vooronderzoek in de vorm van een archeologisch bureau- en booronderzoek had uitgewezen dat in het plangebied op vier verschillende niveaus een middelhoge verwachting gold voor archeologische resten vanaf de Brons- of IJzertijd tot aan de Late Middeleeuwen.
De archeologische opgraving heeft de verwachting bevestigd en op vier niveaus archeologische
resten opgeleverd. Het diepst gelegen archeologische niveau bevat sporen en vondsten uit de Late
IJzertijd of Vroeg Romeinse tijd. Op dit niveau zijn tevens enkele vondsten uit de Vroege en Midden
IJzertijd gedaan, die zouden kunnen aangeven dat minimaal één van de sporen, een mogelijke kuil,
uit deze periode stamt. De IJzertijd vindplaats bestaat uit een complex van greppels en kuilen. Het
onderzoek heeft niet met zekerheid kunnen uitwijzen wat de functie van de vindplaats was. In
minstens één van de greppels stond licht brak water. Mogelijk dienden de greppels en kuilen voor de
ontwatering van het gebied of als drinkwaterkuilen voor vee. Ook een functie als percelering is
mogelijk. De sporen kunnen worden geïnterpreteerd als off-site sporen die horen bij een nederzetting
die waarschijnlijk hoger heeft gelegen, bijvoorbeeld op de strandwal ten noordwesten van het
plangebied. Waarschijnlijk bestaat er een relatie tussen deze vindplaats en de vindplaats die 70 m
naar het zuidoosten aan de Van Panhuysstraat is aangetroffen. Op die vindplaats werden eveneens
een akkerlaag, greppels, paalgaten (zonder structuur) en eergetouwsporen aangetroffen.
Na het in onbruik raken van het systeem van greppels en kuilen is het plangebied in gebruik genomen
als akker. Vondsten uit de akkerlaag geven aan dat deze beakkering mogelijk ook in de Late IJzertijd
of Vroeg Romeinse tijd heeft plaatsgevonden. Deze akker bevond zich alleen in het zuidoosten van
het plangebied, ten zuiden van greppel 54. Greppel 54 vormde mogelijk een begrenzing en deze
greppel en de greppels ten noorden er van kunnen dus zodanig gelijktijdig zijn geweest met de akker
of met het systeem van greppels en kuilen.
Dwars door het plangebied loopt een geul. Het onderzoek heeft niet met zekerheid kunnen aantonen
of de geul gelijktijdig is met de sporen uit de Late IJzertijd of Vroeg Romeinse tijd of pas is ontstaan
na het in onbruik raken van het terrein. De aanwezigheid van kleine visdammen die middels 14Cdatering
zijn gedateerd in de Vroege of Midden Romeinse tijd geeft echter aan dat de geul in deze
periode actief was.
De kreekgeul is twee maal actief geweest met tussen de actieve periodes een periode van
veenvorming. Tijdens de tweede actieve periode, mogelijk in de Middeleeuwen, is het grootste deel
van het veen weer geërodeerd. Na het wederom verlanden van de geul is op de zandige
kleiafzettingen een akker bestaande uit ruggen en laagten aangelegd. Van deze akker zijn alleen
graafsporen waargenomen in de profielen. Deze akker is met jong duinzand overstoven.
De sporen op het hoogste archeologische niveau dateren uit de Nieuwe tijd A en B. Er zijn een grote
waterput, drie kleine tonputten, enkele kuilen en een aantal concentraties van paalsporen
aangetroffen. In de paalsporen zijn geen structuren herkend. De sporen hangen vermoedelijk samen
met een boerderij die buiten het plangebied stond; op de kaart van het hoogheemraadschap van begin 17e eeuw staat aangegeven dat aan deze zijde van de Duinweg huisplaatsen aanwezig waren
Apophatic Elements in the Theory and Practice of Psychoanalysis: Pseudo-Dionysius and C.G. Jung
No full textThis thesis identifies apophatic elements in the theory and practice of psychoanalysis through an examination of Pseudo-Dionysius and C.G. Jung. Pseudo-Dionysius brought together Greek and Biblical currents of negative theology and the via negativa. The apophatic concepts and metaphors which appear in the work of Pseudo-Dionysius are identified. The psychology of Jung can be read as a continuation and extension of the apophatic tradition. The presence of neoplatonic themes in Jung’s work is discussed, as well as his references to Pseudo-Dionysius. There is a thorough examination of Jung’s discussion of opposites, including his reception of Nicholas of Cusa’s concept of the coincidence of opposites. The role of the transcendent function in Jung’s psychology is reviewed. The work of contemporary scholars of religion, philosophers and Jungian theorists are compared to Jung’s using the lens of apophasis. There is an exploration of ways in which motifs in Pseudo-Dionysius’ Ecclesiatical Hierarchy resonate with contemporary psychoanalytic psychotherapy. This study demonstrates that apophatic motifs saturate Jung’s work. It provides a platform for research into apophasis in the wider field of psychoanalysis
C.G. Jung et les théologiens
No full textHélène Kiener. C.G. Jung and the theologians. (C.G. Jung et les théologiens.)
This article is by one of the students of the psychologist C.G. Jung. She practised as a Jungian psychoanalyst in Strasbourg from 1946 to 1970. She deals here with the theological dimension, mostly implicit, of Jung's thouth, which is generally overlooked by theology. The author shows how the major theologians, who are the exception to the general rule, make room for Jungian anthropology, and she calls for a more open attitude in theology, because of the light thrown by Jung's thought on many theological statements.L'article qu'on lira est d'une élève du psychologue des profondeurs C. G. Jung. Elle a pratiqué elle-même l'analyse jungienne à Strasbourg de 1946 à 1970. La question traitée porte sur la dimension théologique généralement implicite de la pensée de Jung, assez négligée d'une manière générale par la théologie. L'auteur expose la manière dont les principaux théologiens, qui font exception , font droit à l'anthropologie jungienne, et en appelle à une ouverture plus grande de la théologie en raison de la lumière que la pensée de Jung jette sur bien des affirmations théologiques.Kiener Hélène.

An Investigation of Transitional Phenomena from Laminar to Turbulent Natural Convection using Compressible Direct Numerical Simulation
No full textThe transitional phenomena from laminar to turbulent natural convection and the development process inside the channel are investigated using compressible direct numerical simulation (DNS). Numerical method of Roe scheme with preconditioning and dual time stepping are used for addressing natural convection flows with large temperature differences, which are low speed but the densities are variable. The results are qualitatively well consistent with the experimental data [1] and the transition point can be accurately captured. In addition, the development process respected to time can be clearly identified for four stages, which are laminar, unstable process, reliminarization and turbulence. After reaching the quasi-steady state, it can be observed that the laminar, transition and turbulence coexist in the same flow filed. Most important of all, the transitional phenomena are naturally induced by the effects of interactions between the buoyancy and shear stress without adding any fluctuations at inlet. It means that the numerical scheme and physical model adopted in this study has the potential to be a universal case for estimating the accuracy of turbulence model because the characteristics of parameters-free and independence from inlet condition
Poiesis and Obstruction in Art Practice
No full textThis PhD thesis examines the concept of poiesis, that is ‘calling into existence that which was not there before’, in the context of obstruction in studio practice. It poses the question ‘Is there a methodology that engages with obstruction which in turn calls new work’? In this thesis, the concept of poiesis emerging from the late Dr. Murray Cox’s ‘Aeolian Mode’, is analyzed alongside a concept of praxis, (a philosophical companion to poiesis), familiar to artistic practice. This thesis describes the orientation of the original idea, The Aeolian Mode, clinically developed by Dr. Murray Cox in Broadmoor Psychiatric Hospital. This PhD seeks to identify if there are similar ‘tenets of approach’ held within the methodology of ‘The Aeolian Mode’, that would be useful or are identifiable in artistic studio practice. This thesis draws on the work of the philosopher, Professor Richard Kearney, specifically Kearney’s ideas on the necessity of ‘the other’ for ‘radical possibility’ to occur. It maps a context of both Freudian and Jungian interpretations of art practice, identifying how these ideas have shaped the way art is seen today. Furthermore, it challenges the Freudian idea of ‘pathography’ and favours a Jungian approach of ‘individuation’ in the understanding of creative processes. It develops a ‘methodology of the conversation’, interviewing students, established artists, tutors about their approaches to obstruction/poiesis in art practice. Additionally, it examines my own obstruction to painting and identifies the methodology that released me from this obstruction. Conducting these interviews on art practice has enabled me to confirm my initial concerns about Freudian ‘pathography’ whilst validating the possibility of the Jungian concept of ‘individuation’ being of use to art practice. Finally, this PhD discusses the implications for further study and research, which have emerged during the ‘methodology of the conversation’ and the task of dissolving my obstruction to painting
The kinase DYRK phosphorylates protein-synthesis initiation factor eIF2B epsilon at Ser(539) and the microtubule-associated protein tau at Thr(212): potential role for DYRK as a glycogen synthase kinase 3-priming kinase
No full textThe substrate specificity of glycogen synthase kinase 3 (GSK3) is unusual in that efficient phosphorylation only occurs if another phosphoserine or phosphothreonine residue is already present four residues C-terminal to the site of GSK3 phosphorylation. One such substrate is the e-subunit of rat eukaryotic protein-synthesis initiation factor 2B (eIF2Be), which is inhibited by the GSK3-catalysed phosphorylation of Ser535. There is evidence that GSK3 is only able to phosphorylate eIF2Be at Ser535 if Ser539 is already phosphorylated by another protein kinase. However, no protein kinases capable of phosphorylating Ser539 have so far been identified. Here we show that Ser539 of eIF2Be, which is followed by proline, is phosphorylated specifically by two isoforms of dual-specificity tyrosine phosphorylated and regulated kinase (DYRK2 and DYRK1A), but only weakly or not at all by other 'proline-directed' protein kinases tested. We also establish that phosphorylation of Ser539 permits GSK3 to phosphorylate Ser535 in vitro and that eIF2Be is highly phosphorylated at Ser539 in vivo. The DYRK isoforms also phosphorylate human microtubule-associated protein tau at Thr212 in vitro, a residue that is phosphorylated in foetal tau and hyperphosphorylated in filamentous tau from Alzheimer's-disease brain. Phosphorylation of Thr212 primes tau for phosphorylation by GSK3 at Ser208 in vitro, suggesting a more general role for DYRK isoforms in priming phosphorylation of GSK3 substrates.<br/
Microbial aspects of anaerobic methane oxidation with sulfate as electron acceptor
No full textAnaerobic oxidation of methane (AOM) is an important methane sink in the ocean but the microbes responsible for AOM are as yet resilient to cultivation. It was shown that AOM was coupled to sulfate reduction (SR) and this gave rise to current research which aims to develop a biotechnological process in which methane is used an electron donor for SR. This thesis describes the microbial analysis of an enrichment capable of high rate AOM (286 µmol.gdry weight-1.day-1) coupled to SR using a novel submerged membrane bioreactor system. Initially AOM rates were extremely low (0.004 mmol L-1 d-1), but AOM and SR increased exponential over the course of 884 days to 0.60 mmol L-1 d-1. The responsible organisms doubled every 3.8 months. By constructing a clone library with subsequent sequencing and fluorescent in situ hybridization (FISH), we showed that the responsible methanotrophs belong to the ANME-2a subgroup of anaerobic methanotrophic archaea, and that sulfate reduction is most likely performed by sulfate reducing bacteria commonly found in association with other ANME related archaea in marine sediments. Another relevant portion of the bacterial sequences can be clustered within the order of Flavobacteriales but their role remains to be elucidated. FISH analyses showed that the ANME-2a cells occur as single cells without close contact to the bacterial syntrophic partner. Incubation with 13C labeled methane showed substantial incorporation of 13C label in the bacterial C16 fatty acids (bacterial; 20, 44 and 49%) and in archaeal lipids, archaeol and hydroxyl-archaeol (21 and 20%, respectively). This confirms that both archaea and bacteria are responsible for the anaerobic methane oxidation in a bioreactor enrichment inoculated with Eckernförde bay sediment. To unravel the pathway of this syntrophic conversion, the effect of possible intermediates on AOM and SR was assessed. To investigate which kind of waste and process streams can be treated by the methanotrophic sulfate-reducing enrichment, the effect of environmental conditions and different substrates was assessed. The optimum pH, salinity and temperature for SR with methane by the enrichment were 7.5, 30‰ and 20°C, respectively. The biomass had a good affinity for sulfate (Km 75 KPa) and AOM was completely inhibited at 2.4 (±0.1) mM sulfide. The enrichment utilized sulfate, thiosulfate, sulfite and elemental sulfur as alternative electron acceptors for methane oxidation and formate, acetate and hydrogen as alternative electron donors for sulfate reduction. As a co-substrate for methane oxidation only methanol stimulated the conversion of 13C labeled CH4 to 13CO2 in batch incubations of Eckernförde bay sediment, other possible co-substrates had a negative effect on the AOM rate. The research described in this thesis shows the possibility of enriching slow growing methane oxidizing communities but also shows the difficulties in applying this process for a biotechnological purpose because of the extreme slow doubling times and the lack of understanding of the metabolic routes used by these organisms. <br/
