A Cultural Genealogy of the Royal Court Theatre: the Renovation of a Theatre and an Ideal.

The Royal Court Theatre\u27s current renovation invites a reexamination of the English Stage Company (ESC). The ESC has entered a crucible of change, raising new questions concerning the Royal Court\u27s architectural semiotics and company\u27s aesthetic mission as London\u27s most acclaimed producer of new plays. This study seeks to understand the ways in which its identity has been shaped and consolidated over the last forty-two years and how the current chapter in ESC history redefines the company\u27s identity and future achievement. The English Stage Company took over the Royal Court in early in 1956. The ESC\u27s marriage with the theatre appears serendipitous in retrospect, because key elements of the ESC\u27s mission correspond to characteristic events from the building\u27s history. The institutionalization of the ESC/Royal Court during the late nineteen eighties and early nineteen nineties ensured that the identity of theatre company and theatre building became indistinguishable. The current rebuilding program endeavors to retain the ghosts of the building\u27s past and the intimacy of its auditorium while transforming a late Victorian receiving house into a flexible, modern, producing theatre capable of juxtaposing new plays against the context of the traditional proscenium stage. Recognizing the complex cultural matrix that embeds the theatrical event, this study employs both a synchronic and diachronic approach when exploring the cultural genealogy of the Royal Court. The study begins with the sequence of events during the nineteen nineties that led the company to undertake a twenty-six million pound rebuilding program. It then traces three strands of history that entwined to become the story of the single entity known as the Royal Court: the history of the building, the independent theatre movement in England, and the English Stage Company. It takes a detailed look at the plan of the current renovation project and the image of the Royal Court it presents. The conclusion attempts to discern the future challenges of the Royal Court following its return home in the year 2000

The Nature Of The Wall Between Generative And Vegetative Nuclei In The Pollen Grain Of Tradescantia Paludosa

FINE STRUCTURE OF CHROMOSOMES

Electron micrographs of staminate hair cells of Tradescantia reflexa indicate that early prophase chromosomes are composed of a number of helically arranged chromonemata. Favorable preparations reveal as many as 64 identifiable subsidiary strands, assumedly arranged as intertwined pairs to form a hierarchy of pairs of pairs. The helices of the smallest discernible units have a diameter of about 125 A, with highly electron-scattering material disposed peripherally around a less dense "core." The wall of this peripheral ring has a thickness of about 40 A, and apparently represents another pair of coiled threads surrounding a 40 A central axis. The implications of the findings are discussed briefly

Histone-protein transition in Drosophila melanogaster : I. Changes during spermatogenesis

The basic protein of the mature spermatozoa of Drosophila melanogaster is an arginine-rich histone but not a protamine, as determined by cytochemical criteria.The histone shift during spermatogenesis occurs during maturation of the sperm rather than at the spermatid stage."Maturity" of a spermatozoon should not be defined purely on morphological criteria. Adjudged cytochemically, the spermatozoa of the early pupal testis of Drosophila cannot be considered as mature; mature sperms first appear shortly before eclosion.The sperm nucleus, by the very nature of its nucleohistone complex, is assumedly devoid of any synthetic activity. This appears to be an evolutionary adaptation for insulating the genetic information during the period of its transit from one generation to the next.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/32103/1/0000153.pd

Compressive behavior and failure mechanisms of freestanding and composite 3D graphitic foams

Open-cell graphitic foams were fabricated by chemical vapor deposition using nickel templates and their compressive responses were measured over a range of relative densities. The mechanical response required an interpretation in terms of a hierarchical micromechanical model, spanning 3 distinct length scales. The power law scaling of elastic modulus and yield strength versus relative density suggests that the cell walls of the graphitic foam deform by bending. The length scale of the unit cell of the foam is set by the length of the struts comprising the cell wall, and is termed level I. The cell walls comprise hollow triangular tubes, and bending of these strut-like tubes involves axial stretching of the tube walls. This length scale is termed level II. In turn, the tube walls form a wavy stack of graphitic layers, and this waviness induces interlayer shear of the graphitic layers when the tube walls are subjected to axial stretch. The thickness of the tube wall defines the third length scale, termed level III. We show that the addition of a thin, flexible ceramic Al2O3 scaffold stiffens and strengthens the foam, yet preserves the power law scaling. The hierarchical model gives fresh insight into the mechanical properties of foams with cell walls made from emergent 2D layered solids
