Brass Art: A house within a house within a house within a house

Performances from Brass Art (Lewis, Mojsiewicz, Pettican), captured at the Freud Museum, London, using Kinect laser scanning and Processing, reveal an intimate response to spaces and technologies. ‘A house within a house within a house within a house’ links historical and cultural representations of the double, the unconscious and the uncanny to this artistic practice. The new moving-image and sonic works form part of a larger project to inhabit the writing rooms of influential authors, entitled ‘Shadow Worlds | Writers’ Rooms’

Folds in Time: Artists' Responses to the Temporal and the Uncanny. An international conference, convened by Brass Art in association with the Freud Museum London, as part of the Festival of the Unconscious 2015.

This conference brings together artists, curators and writers to examine the ways artists harness aspects of the uncanny and the unconscious in their navigation of physical and imagined spaces. Built around artists’ practices which have responded to the repressed, the unthought or the untold, and which employ fractured, dream-like or metamorphic narratives; the conference will mix keynote addresses with artist-in-conversations. Contributions from: Patricia Allmer , Rachel Anderson (Artangel), Brass Art, Rebecca Fortnum, Pavel Pyś , Alison Rowley , Lindsay Seers, Daniel Silver , Saskia Olde Wolbers, Rachel Withers. Keynote Lectures: Dr Alison Rowley 'Uncanny Returns and the Power of Laughter: Sarah Lucas at the Freud Museum' Dr Patricia Allmer 'Shadowdance - The Mobile Uncanny

The interpretative ability of coefficient R2 to calculate the firm value

Several studies have focused on the relationship between the R2 and the firm value. They have tried to explain how different values of R2 affect the firm value. In this paper we examine this relationship for the Greek companies listed on the Greek Stock Exchange, analyzing a sample of 135 listed companies for the 2004 - 2010 period. The results reveal that R2 is inversely related to the firm value. This is consistent with the model of Dow and Gorton (1997). Moreover, we found that companies with high R2 have significantly higher returns than those with low R2, over a two year period time, which is inconsistent with the findings of Stowe and Xing (2011). Moreover, this research shows that the investment decisions are likely to be based more on investor psychology rather than an analysis of firm-specific information

Functional evidence for cone-specific connectivity in the human retina

NoPhysiological studies of colour vision have not yet resolved the controversial issue of how chromatic opponency is constructed at a neuronal level. Two competing theories, the cone-selective hypothesis and the random-wiring hypothesis, are currently equivocal to the architecture of the primate retina. In central vision, both schemes are capable of producing colour opponency due to the fact that receptive field centres receive input from a single bipolar cell ¿ the so called `private line arrangement¿. However, in peripheral vision this single-cone input to the receptive field centre is lost, so that any random cone connectivity would result in a predictable reduction in the quality of colour vision. Behavioural studies thus far have indeed suggested a selective loss of chromatic sensitivity in peripheral vision. We investigated chromatic sensitivity as a function of eccentricity for the cardinal chromatic (L/M and S/(L + M)) and achromatic (L + M) pathways, adopting stimulus size as the critical variable. Results show that performance can be equated across the visual field simply by a change of scale (size). In other words, there exists no qualitative loss of chromatic sensitivity across the visual field. Critically, however, the quantitative nature of size dependency for each of the cardinal chromatic and achromatic mechanisms is very specific, reinforcing their independence in terms of anatomy and genetics. Our data provide clear evidence for a physiological model of primate colour vision that retains chromatic quality in peripheral vision, thus supporting the cone-selective hypothesis

Experimental investigation of the processes of dehumidification of coniferous biomass

This work includes the results of experimental studies of the moisture removal processes in the temperature range from 333 K to 413 K from coniferous woods which are typical for many regions. There are obtained the dependences of the mass rate of moisture removal on time and temperature. The effect of the evaporation of bound moisture was identified for the wood species studied. There are calculated the accommodation coefficient and the partial pressure at the evaporation surface for each type of biomass

Síntesis y catálisis de las perovskitas MgTiO3 y CaTiO3

Las Perovskitas son una especie de solidos cristalinos que catalizan reacciones de degradación en colorantes, en el siguiente artículo se expresa el proceso de obtención de dichas perovskitas( MgTiO3 Y CaTiO3,) por el método de Pechini con algunas variaciones, y posteriormente se evaluó su actividad fotocatalitica en el colorante azul de metileno, bajo la radiación producida en el reactor de luz negra y el reactor de luz UV-VIS y se determinaron algunos parámetros (variación de la concentración de azul de metileno durante la reacción en determinados tiempos de reacción ,% de absorción, % de degradación; que nos permitieron determinar si los sistemas son catalíticamente activos
