Interview With P.C. Hodgell
No full textP.C. Hodgell, author of God Stalk and Dark of the Moon, was one of the many authors who attended Mythcon XIX in Berkeley last summer. She was good enough to meet with the Mythic Circle writers\u27 roundtable and share some of her experiences with us. The following is transcribed from a low-quality tape; when it was possible to recognize a speaker’s voice I have identified them - others are noted as ct. Hope you enjoy it
Nonequilibrium and classical dissipation scalings in DNS of homogeneous isotropic decaying turbulence
No full textWe present data from direct numerical simulations of homogeneous isotropic decaying turbulence showing both the non-equilibrium and the classical dissipation scalings reported in wind-tunnel experiments of both regular and fractal grid-generated turbulence, i.e. Cε ∼ (Re0/Reλ)n with n of order unity and Cε ∼ constant, respectively (Re0 and Reλ are global and local Reynolds numbers). These two dissipation behaviours lead to different power-law decay exponents in both regimes also in accord with the experiments. Finally, we show that in both regimes the maximum non-linear energy cascade flux, Π, reasonably satisfies the classical expectation that Π ∼ K3/2/l

Dendritic spine density and EphrinB2 levels of hippocampal and anterior cingulate cortex neurons increase sequentially during formation of recent and remote fear memory in the mouse
No full textMemory consolidation is a dynamic process that involves a sequential remodeling of hippocampal–cortical circuits. Although synaptic events underlying memory consolidation are well assessed, fine molecular events controlling this process deserve further characterization.
To this aim, we challenged male C57BL/6N mice in a contextual fear conditioning (CFC) paradigm and tested their memory 24 h, 7 days or 36 days later. Mice displayed a strong fear response at all time points with an increase in dendritic spine density and protein levels of the cell adhesion factor EphrinB2 in CA1 hippocampal neurons 24 h and 7 days post conditioning (p.c.), and in anterior cingulate cortex (ACC) neurons 36 days p.c. We then investigated whether the formation of remote memory and neuronal modifications in the ACC would de- pend on p.c. protein synthesis in hippocampal neurons. Bilateral intrahippocampal infusions with the protein synthesis inhibitor anisomycin administered immediately p.c. decreased fear response, neuronal spine growth and EphrinB2 protein levels of hippocampal and ACC neurons 24 h and 36 days p.c., respectively. Anisomycin infusion 24 h p.c. had no effects on fear response, increase in spine density and in EphrinB2 protein levels in ACC neurons 36 days p.c. Our results thus confirm that early but not late p.c. hippocampal protein synthesis is necessary for the formation of remote memory and provide the first evidence of a possible involvement of EphrinB2 in neuronal plasticity in the AC
Les thermes de Chassenon (Charente) : transformation et réoccupation (IVe-VIe s. p.C.)
No full textThe recent excavations (1998-2000) of the Longeas thermal baths (Chassenon, Charente) help us to understand the evolution, both private and civil, and reoccupation of this construction from the 4th to the 6th century AD. Here we follow the transformation of a gallo-roman public building, in the heart of an peri-urban sanctuary into a rural hamlet composed of juxtaposed workshops and living quarters. Reconstructed at the beginning of the 4th century, the thermal baths were reoccupied without prior destruction or abandon, as early as the first third of the 5th century by a series of large dwellings linked to storage and grain preparation areas. From the end of the 5th century to the beginning of the 6th century, a second phase, richer and better structured, corresponds to the last occupation of the site, after nearly 500 years of continuous occupation. This evolution should certainly be interpreted in the more general context of Christianisation and the Visigothic settlement in this region during the 5th century AD.Les fouilles récentes (1998-2000) des thermes de Longeas (Chassenon, Charente) permettent d’appréhender l'évolution et la réoccupation privative et domestique de cet édifice du IVe au VIe s. p.C. On y suit la transformation d’un bâtiment public gallo-romain, au cœur d’un sanctuaire périurbain, en un hameau rural composé de cellules d’habitat et d’artisanat juxtaposées. Reconstruits au début du IVe s., les thermes sont réoccupés, sans destruction ni abandon préalables, dès le premier tiers du Ve s. par une série de grandes habitations, liées à des zones de stockage et de préparation des grains. De la fin du Ve s. au début du VIe s., une seconde phase, plus riche et mieux structurée, correspond à la dernière occupation du site, après presque 500 ans d’utilisation continue de celui-ci. Il convient sans doute d’interpréter cette évolution dans le contexte plus général de la christianisation et de l’implantation wisigothique dans cette région au cours du Ve s. p.C.Hourcade David, Lebreton Stéphane.

Reinforcing glass with glass: Application of transport reinforcement in structural glass beams
No full textDue to the increasing demand of transparency in buildings, it is no longer unusual to apply transparent elements into the bearing structure. Glass is a strong but very brittle material, which means safety is rather problematic should it break. Safety is an issue that has to be improved before glass can be considered suitable for structural elements. Earlier studies have shown that reinforcing glass beams will provide reasonable residual load-bearing capacity, which could provide this safety. Glass fibre is suitable as reinforcement material when the transparency is regarded as important. In February 2009 at the Faculty of Architecture at Delft University of Technology, P.C. Louter designed and tested a laminated glass beam with embedded glass fibre rods. The bonding interlayer consisted of SentryGlas foil, developed by DuPont and often applied for lamination in hurricane-resistant windows. The results were promising and the concept showed high potential for further research. The study of this thesis project is focussed on improving the concept of embedding reinforcement in laminated glass beams.Design and ConstructionCivil Engineering and Geoscience
