Spectacular Developments: Guy Debord's Parapolitical Turn
No full textFollowing the attacks of September 11th, 2001, Guy Debord’s concept of ‘the
spectacle’ re-emerged in the work of a variety of theorists as a critical prism through
which the attacks and subsequent ‘War on Terror’ could be approached. Debord’s
first book on the spectacle (1967) was written in the context of France’s post-war
boom; his later reflections, contained in a series of minor works written throughout
the seventies and eighties, are heavily influenced by Italy’s ‘Years of Lead’ and a
broader geopolitical climate of armed struggle, terrorism, counter-insurgency and
espionage. Nearly all post-9/11 invocations of Debord’s concept draw on the version
elucidated in Debord’s 1967 book, with its emphasis on commodity fetishism,
ideology, and alienation, and fail to engage his later work and its focus on terrorism,
secrecy, and conspiracy. Among those that do in fact reference Debord’s later work
are several writers whose work could pejoratively be labelled ‘conspiracy theory’.
Looking at Debord’s oeuvre as whole, and investigating how it combines a critique of
late capitalism in its totality with parapolitcal concerns of ‘systemic clandestinity’,
Spectacular Developments: Guy Debord’s Parapolitical Turn provides a bolstered
conception of the spectacle that aims to reconfigure the conceptual foundations of this
debate. This conception of the spectacle allows one to approach the 9/11 attacks and
all that followed in their wake with both a precision and a breadth lacking in these
other works, demonstrating the superficiality of readings that make the concept
synonymous with the mass media or that attempt to unravel nefarious conspiracies of
power. Simultaneously, this approach foregrounds the epistemological and strategic
challenges faced by researchers, politicians and activists working in and on the
society of the spectacle
Towards the tumble resistant microlight
No full textThe tumble mode is a pitching departure from controlled flight which leads to a pitch autorotation that is generally unrecoverable – resulting in vertical ground impact, usually preceded by in-flight breakup (the mechanism for which, surprisingly, can sometimes prevent loss of life). This was identified in work led by the British Microlight Aircraft Association beginning in 1997 as a response to a number of fatal accidents in Rogallo winged microlight aeroplanes, although the tumble is also known to occur to hang-gliders. This paper explains how this class of aeroplane is controlled, and how it has been found that they can enter the tumble mode. The mechanism by which the tumble can be entered is described. This has led to work showing how flight testing can be used to establish and demonstrate resistance to tumble entry – particularly important with increasing number of very high performance flexwings. These flight tests will be explained, together with the significance of the results. Recent accident investigation work has also shown a new mechanism of tumble entry, through partial failure of the A-frame structure and the pitch-trimmer mechanism. Also described is a possible relevance to well known historical accidents to flying wing aeroplanes– specifically the YB-49 and dH-108, and discovered data on the characteristics of the BKB-1flying wing glider; are also described
The discovery of SycO reveals a new function for type three secretion effector chaperones
No full textThe Type Three Secretion (T3S) system is a device used by many Gram-negative pathogens that allows bacteria to deliver effector proteins straight into the eukaryotic cell cytosol. These effectors interfere with various signaling pathways to subvert the host cell functions. The secretion machinery of the T3S system consist of a basal body spanning the bacterial inner and outer membrane followed by a stiff hollow needle outside the bacterium. The fully assembled secretion apparatus constitute a continuous hollow conduit that connects the bacteria to the eukaryotic target cell. After cell contact, virulence proteins -called effectors- are injected directly into the cytosol of the host cell via the T3S apparatus. Several effectors of the T3S system require the assistance of specific cytosolic chaperones to be efficiently exported. There are three classes of T3S chaperones. Effector proteins are assisted by Class I chaperones. Although Class I chaperones are well characterized, their main function is still a matter of controversy. In this thesis, we demonstrate that orf155 encodes a specific chaperone for the effector YopO that we called SycO. We showed that SycO enhances YopO secretion in vitro and is required for translocation of YopO into infected cells. By pulldown assay we demonstrated that residues 20 to 77 of YopO are required and sufficient for SycO binding. Using crosslinking experiments and size exclusion chromatography analysis, we determined the stoichiometry of purified SycO and YopO-SycO complexes. SycO alone forms dimers in solution and the YopO-SycO complex has a 1:2 stoichiometry. These results suggested that SycO is a typical chaperone of the Class I. YopO is a serine/theronine kinase that interacts with Rho and Rac and disrupts the cytoskeleton of the target cells. YopO has been shown to localize at the cell plasma-membrane. By transfection of YopO-EGFP hybrid proteins into HEK293T cells, we demonstrated that the chaperone-binding domain (CBD) coincides with the membrane localization domain of YopO. Nevertheless, the CBD was not needed for the kinase activity of YopO. By ultracentrifugation, we also showed that the CBD causes YopO aggregation in the bacteria, when SycO does not cover it. Further, we show that the CBD of YopE and YopT also caused aggregation in the bacteria in the absence of SycE and SycT respectively. YopE, YopT and T3S effectors in other systems also act at the membrane of the eukaryotic host cell. We propose a new hypothesis concerning the role of T3S chaperones. The sub-cellular localization domain of effectors is aggregation-prone and creates the need for a chaperone inside bacteria. We propose that masking such aggregation-prone localization domains may be a general function for type III effector chaperones
Guy de Maupassant playwrite
No full textThis thesis focuses on presenting Guy de Maupassant, a French writer of the second half of the 19th century, as a playwriter. The main objective of the thesis is to disclose the dramatic tendencies of the writer, who is primarily known for his prose, and to present all the seven completed dramatic pieces which are often neglected in favour of his more famous work. The thesis aims to showcase the nature and the position of the plays in the context of Guy de Maupassant´s whole work and their overall perception. It attempts to explain the author´s specific approach through describing the social and historical atmosphere, literary and theatre movements in the second half of the 19th century and through analysis of the plays themselves. Based on these the thesis offers a way how to fully perceive de Maupassant´s plays. Of significant importance are the selected quotations of textes of the plays. Finally the thesis presents the common signs of the plays and tries to discover the initial intention of their creation, the author´s approach to the genre and the reason why they last unknown in general
Remembering a Time Before the Great Culture War
No full textGuy Mankowski offers some reflections on the culture war of 2021. Mankowski is the author of the upcoming book Albion's Secret History, a book that compiles snapshots of English pop culture’s rebels and outsiders, from Evelyn Waugh to PJ Harvey via The Long Blondes and The Libertines. By focusing on cultural figures who served to define England, Guy Mankowski looks at those who have really shaped Albion’s secret history, not just its oft-quoted official cultural history.</p
The tumble mode - where test pilots fear to tread
No full textFollowing a fatal accident in 1997 and identification of common patterns in several (usually fatal) previous accidents the AAIB (United Kingdom Air Accidents Investigation Branch) asked the BMAA (British Microlight Aircraft Association) to pursue a course of investigation into the tumble mode, which had been attributed as the primary cause of that fatal accident.
The tumble mode is a peculiarity of weightshift controlled aircraft - that is flexwing microlights and hang-gliders. It is a departure from controlled flight leading to a nose-down pitch autorotation: pitch rates of 400°/s are known. When a tumble occurs in a microlight aeroplane, it is rare for the crew to survive and loss of the aircraft is universal

Calculational model for first-mode eigenfrequency of a semi-guy-wired vertical-axis wind turbine tower
No full textA simple model for accounting for tower mass when estimating the first-mode eigenfrequency of a semi-guy-wired tower has been derived. This extends previous work where an analytical model of the semi-guy-wired tower of a 200-kW vertical-axis wind turbine was developed. The model was primarily used to estimate the eigenfrequencies as a result of adding guy wires to a free-standing tower (thus creating a semi-guy-wired setup). However, a weakness with the model was that the tower mass was accounted for in a rough way that essentially ignored the guy wires, which gave a larger-than-necessary error. In this work, an effective top mass, that takes into account the tower mass and the constraints from the guy wires, is derived to achieve a higher accuracy when estimating the first-mode eigenfrequency. This, together with the earlier models, gives a more complete method to estimate the eigenfrequencies for a semi-guy-wired wind turbine. © The Author(s) 2019.</p
