A Thorny Rose Bush and Other Greenery:Love, Lust and Suffering in the<i> Romance of the Rose</i>
No full textRoses are ambiguous in nature. Associated with Aphrodite, they stand for love and lust, but also for the sharp thorns of heartache. The rose is an ode to the Virgin Mary, while it also symbolizes the suffering of Christ. In the Romance of the Rose, in which a rose bush plays the leading role, this ambiguity is also expressed. The garden where the bush grows is a heavenly paradise, but also a garden of lust. The love of the narrator for one of the rosebuds is sweet, but also heart-breaking because he is not allowed to touch it. When he nevertheless indulges himself on the bud, this leads to the end of the bud, but fills him with bliss

A direct borohydride – acid peroxide fuel cell
No full textA fuel cell operating with aqueous sodium borohydride and hydrogen peroxide streams, with one, two and four cells (electrode area 64, 128 and 256 cm2) connected in a bipolar mode in a filterpress flow cell is reported. The oxidation of borohydride ion was carried out on Au/C particles supported on a carbon felt electrode while the reduction of hydrogen peroxide was carried out on carbon supported Pt on a carbon paper substrate. Comparable cell potentials and power densities to direct borohydride fuel cells reported in the literature were obtained. The challenges to further development includes: increasing the low current density and avoid decomposition of borohydride and peroxide ions. The maximum power obtained at 20oC for one, two and four cell stacks was 2.2, 3.2 and 9.6 W (34.4, 25 and 37.5 mW cm-2 respectively) with cell voltages of 1.06, 0.81 and 3.2 V at current densities of 32, 16 and 12 mA cm-2, respectively

A computer simulation of groundwater salinization risk in Salento peninsula (Italy)
No full textThe main source of water for civil purposes in Salento peninsula is the coastal karst aquifer. It is formed by Cretaceous units, essentially limestones and dolomitic limestones highly fractured and karstificated. The groundwater is intensively withdrawn and, as a consequence, the risk of contamination of existing wells due to salinization is high. In order to evaluate the level of such a risk, a procedure is proposed that, taking into account the essential features of the underground circulation like the principal conductive fractures and karstic conduits, leads to a predictive model based on the generation by computer of artificial systems of fractures and conduits. Very preliminary results are presented to show the capability of such a procedure
Skeleton-based design and simulation flow for Computation-in-Memory architectures
No full textMemristor-based Computation-in-Memory is one of the emerging architectures proposed to deal with Big Data problems. The design of such architectures requires a radically new automatic design flow because the memristor is a passive device that uses resistance to encode its logic value. This paper proposes a design flow for mapping parallel algorithms on the CIM architecture. Algorithms with similar data flow graphs can be mapped on the crossbar using the same template containing scheduling, placement, and routing information; this template is named skeleton. By configuring such a skeleton with different pre-designed circuits, we can build CIM implementations of the corresponding algorithms in that class. This approach does not only map an algorithm on a memristor crossbar, but also gives an estimation of its performance, area, and energy consumption. It also supports user-defined constraints and parallel SystemC simulation. Experimental results demonstrate the feasibility and the potential of the approach.Accepted Author ManuscriptComputer EngineeringQuantum & Computer EngineeringFTQC/Bertels La
