On necrocapitalism: A plague journal
No full textM.I. Asma is the collective designation for six authors from Canada and the United States, representing a variety of revolutionary anticapitalist theoretical persuasions: J. Moufawad-Paul, Devin Zane Shaw, Mateo Andante, Johannah May Black, Alyson Escalante, and D. W. Fairlane. As the pandemic transitioned from science fiction to reality in early 2020, a number of writers and thinkers in the imperialist metropoles declared the impossibility of writing in the face of a future that is foreclosed. And yet, due to the nightmare that capitalism has been since its beginning, numerous writers and thinkers from the margins have always written in the face of such foreclosure. Meanwhile, other contemporary thinkers sought to conceptualize the unfolding pandemic according to conceptions of bio/necropolitics, forgetting the foundation upon which these conceptions have always existed.
The M.I. Asma writing group came together to stake out a different terrain, thinking through the pandemic as events unfolded while also always working to think beyond the capitalist imaginary. Writing between April 2020 and May 2021, the authors set out to produce a serial theoretical philosophical project focused on class struggle in the midst of the COVID-19 pandemic. The authors approached the pandemic as an occasion to think capitalism according to what it always has been, what the pandemic reveals about its current ideological deployment, and how we can think about a communist alternative in the face of exterminism.
This book collects, with some revisions and with a new epilogue, the entries from the On Necrocapitalism blog, where M.I. Asma’s interventions first appeared.DC Author's celebration 202
Respiratory pattern in awake rats: Effects of motor activity and of alerting stimuli
No full textOur aim was to assess the impact of motor activity and of arousing stimuli on respiratory rate in the awake rats. The study was performed in male adult Sprague–Dawley (SD, n = 5) and Hooded Wistar (HW, n = 5) rats instrumented for ECG telemetry. Respiratory rate was recorded using whole-body plethysmograph, with a piezoelectric sensor attached for the simultaneous assessment of motor activity. All motor activity was found to be associated with an immediate increase in respiratory rate that remained elevated for the whole duration of movement; this was reflected by: i) bimodal distribution of respiratory intervals (modes for slow peak: 336 ± 19 and 532 ± 80 ms for HW and SD, p < 0.05; modes for fast peak 128 ± 6 and 132 ± 7 ms for HW and SD, NS); and ii) a tight correlation between total movement time and total time of tachypnoea, with an R2 ranging 0.96–0.99 (n = 10, p < 0001). The extent of motor-related tachypnoea was significantly correlated with the intensity of associated movement. Mild alerting stimuli produced stereotyped tachypnoeic responses, without affecting heart rate: tapping the chamber raised respiratory rate from 117 ± 7 to 430 ± 15 cpm; sudden side move — from 134 ± 13 to 487 ± 16 cpm, and turning on lights — from 136 ± 12 to 507 ± 14 cpm (n = 10; p < 0.01 for all; no inter-strain differences). We conclude that: i) sniffing is an integral part of the generalized arousal response and does not depend on the modality of sensory stimuli; ii) tachypnoea is a sensitive index of arousal; and iii) respiratory rate is tightly correlated with motor activity.Muammar M.

Cardiorespiratory coordination in rats is influenced by autonomic blockade
No full textAutonomic disturbance creates changes in the modulation of heart rate. In this study we analyzed the influence of sympathetic and vagal blockade on the interaction between cardiac and respiratory rhythms. In seven anaesthetized rats, electrocardiogram (ECG), and respiratory rate were recorded continuously before and after autonomic blockade with either methyl-scopolamine or atenolol. For the assessment of cardiorespiratory coordination, we analyzed the phase locking between heart rate, computed from the R-R intervals of body surface ECG, and respiratory rate, computed from impedance changes, using Hilbert transform. The procedure was carried out for different m:n coordination ratios where, m, is the number of heart beats and n, is the number of respiratory cycles. The changes in percentage of synchronization and duration of synchronized epochs before and after injection were assessed with one-way ANOVA. Sympathetic blockade with atenolol caused an increase (baseline: 0.49 } 0.03s vs. blockade: 0.54 } 0.06s) and vagal blockade with methylscopolamine caused a decrease (baseline: 0.49 } 0.03s vs. blockade: 0.45 } 0.08s) in the duration of synchronized epochs. Neither the overall percentage of synchronized epochs, (baseline: 10.76 } 3.5% vs. blockade 9.44 } 4.3%), nor the average locking ratio, 3:1, was significantly affected by autonomic blockade. In conclusion, the phase-locking between heart rhythm and respiration is modulated by both vagal and sympathetic efferences, in the opposite directionsM.M. Kabir, M.I. Beig, E. Nalivaiko, D.

From granulites to eclogites in the Sesia zone (Italian Western Alps): a record of the opening and closure of the Piedmont ocean
No full textThe Sesia zone (Italian Western Alps) offers one of the best preserved examples of pre-Alpine basement reactivated, under eclogite facies conditions, during the Alpine orogenesis. A detailed mineralogical study of eclogitized acid and basic granulites, and related amphibolites, is presented. In these rare weak to undeformed rocks microstructural investigations allow three main metamorphic stages to be distinguished. The inferred P-T path is consistent with an uplift of continental crust produced by crustal thinning prior to the subduction of the continental rocks. In the light of the available geochronological constraints we propose to relate the pre-Alpine granulite and post-granulite retrograde evolution to the Permo-Jurassic extensional regime. The complex granulite-eclogite transition is thus regarded as a record of the opening and of the closure of the Piedmont ocean. -from Author
Alpine and pre-Alpine tectonics in the Central Orobic Alps (Southern Alps)
No full textA sequence of regional deformation episodes is described in the Permian cover and in the metamorphic basement of a portion of the Southern Alps, southeast of Sondrio (Valtellina). The earliest episode is contemporaneous with low to medium grade metamorphism in the basement; the second episode occurs during low temperature greenschist-facies retrogradation in the basement; these two synmetamorphic regional deformation episodes in the basement are pre-Alpine (probably of Variscan age) and predate the deposition of Permian sediments. Cover and basement are deformed together during a third tectonic episoide of post-Triassic age, unrelated to regional metamorphic reactivation, and associated with nappe emplacment and regional folding, that took place at shallow levels of the Southalpine margin during Alpine time. -Author
Government influence and foreign direct investment: Organizational learning in an electronics cluster
No full textThis article demonstrates government and foreign direct investment in influencing the formation and development of the electronics cluster in Guadalajara, Mexico. The organizational limitations and the lack of planning in the technological learning process aside, the triple helix paradigm has become critical in upgrading the electronics industry in Guadalajara. The study analyzes technology transfer and its adaptation through technical and research cooperation within national and international innovation systems. It also examines the role of multinational corporations within the triple helix model, and how they impact upon the formation, growth and development of an electronics cluster in Guadalajara. © The Author(s), 2010
Contrasting thermomechanical evolutions in the Southalpine metamorphic basement of the Orobic Alps (Central Alps, Italy)
No full textNew petrological and partly new structural data have been obtained for two sectors of the Orobic Alps, traditionally attributed to different metamorphic zones. Thermo-barometric determinations, supported by microstructural analysis, indicate different pressure-retrograde paths in each sector. Reinterpretation of the available geochronological data indicates a diachronism for the two thermo-mechanical evolutions. In the light of these data, we interpret the retrograde P-T-t path of the VVB rocks as a pre-Permian post-thickening uplift and the retrograde P-T-t evolution of the LB rocks as a Permo-Mesozoic uplift related to the extensional tectonic regime of the Tethyan rifting. -from Author
