Shed Light

This article aims to clarify the question of speed and intensity in the thoughts of Simondon and Deleuze, in order to shed light on the recent debates regarding accelerationism and its politics. Instead of starting with speed, we propose to look into the notion of intensity and how it serves as a new ontological ground in Simondon's and Deleuze's philosophy and politics. Simondon mobilises the concept of intensity to criticise hylomorphism and substantialism; Deleuze, taking up Simondon's conceptual framework, repurposes it for his ontology of difference, elevating intensity to the rank of generic concept of being, thus bypassing notions of negativity and individuals as base, in favour of the productive and universal character of difference. In Deleuze, the correlation between intensity and speed is fraught with ambiguities, with each term threatening to subsume the other; this rampant tension becomes explicitly antagonistic when taken up by the diverse strands of contemporary accelerationism, resulting in two extreme cases in the posthuman discourse: either a pure becoming, achieved through destruction, or through abstraction that does away with intensity altogether; or an intensity without movement or speed, that remains a pure jouissance. Both cases appear to stumble over the problem of individuation, if not disindividuation. Hence, we wish to raise the following question: in what way can one think of an accelerationist politics with intensity, or an intensive politics without the fetishisation of speed? We consider this question central to the interrogation of the limits of acceleration and posthuman discourse, thus requiring a new philosophical thought on intensity and speed.

Annotated Checklist

An annotated checklist of the pleurocarpous moss genus Plagiothecium in Eurasia is presented for the first time based on a thorough review of the literature. Data have been compiled from previous relevant works conducted on the genus over more than 70 years and published up to the end of June 2020 for 107 Eurasian countries (and islands). Sectional classification is based on molecular phylogeny of the genus published recently. A total of 41 taxa are reported, including 29 species and 12 infraspecific taxa (nine varieties and three forms) belonging to eight sections. The highest numbers of taxa were found in China (20 taxa), the Russian Federation (20 taxa) and Japan (18 taxa), while the smallest numbers of taxa were recorded in the Middle East, Central Asia and the islands area. Not a single species of Plagiothecium was recorded in 26 regions, whereas P. denticulatum, P. nemorale and P. cavifolium turned out to be the most widespread species in the entire study area. They were recorded in most of the surveyed countries and islands. For each accepted taxon, information on relevant literature, synonyms, distribution within Eurasia and globally are provided. Comments on each taxon, ecological preferences, and notes on doubtful records are also included. Additionally, distribution maps for each recognised taxon are supplied. This checklist can enlighten and foster a better understanding of the distribution, diversity, and ecology of Plagiothecium in Eurasia and provides an incentive for future research on the genus.

This study presents the first records of the subfamily Lestremiinae and the genus Insulestremia Jaschhof in Brazil. Insulestremia, a previously monotypic genus described from the Galapagos Islands, has three species in Brazil: I. sinclairi Jaschhof, I. amorimi sp. nov. and I. amenti sp. nov. The new species are described, the generic concept is reviewed, and a key to the species of Insulestremia is provided.

TheEosaukiafauna is proposed for the upper Furongian trilobite assemblage from the interval spanning from the upper part of the Hwajeol Formation to the lowermost part of the Dongjeom Formation in the Taebaek Group, Taebaeksan Basin, Korea. It is characterized by the dominance of dikelocephalid trilobites comprisingEosaukia micropora, E. bella, E. acuta, Mictosaukiacf.M. globosa, andTaebaeksaukia spinatan. gen. n. sp. Taxonomic reappraisal of the genusMictosaukiathat has been employed as an upper Cambrian index taxon in eastern Gondwana reveals that more than half of the species ofMictosaukiabelong inEosaukia.This study clarifies the generic concept ofEosaukia, which provides a more reliable biostratigraphic correlation for the upper Furongian strata in eastern Gondwanan regions. TheEosaukiafauna is correlated with the“Mictosaukia”faunas from the upper Fengshanian of North China, upper Taoyuanian of South China, and upper Payntonian of Australia.

Since the British philosopher John Austin, narratives and performatives have been con­sidered as opposite concepts covered by the generic concept of speech act. At the same time, these concepts were separated according to whether a narrative, inducement, a description, or an imperative was present in the text. Similar to the narrative, the performative is created under pressure from various external factors associated with the system of public communica­tions, to which the author is exposed, and a multitude of reasons that reflect in his or her mind external processes. All these factors and influences transmute in the course of text crea­tion; the viewer/reader consumes ready-made information, which invariably bears an imprint of the author's habitus. When creating a text, the author conveys his or her desires and ex­presses his or her attitude to the chosen problem. This study aims to answers two questions. Can a narrative have at its core an explicit manipulative basis or a hidden motive? Can the picture of the world, which develops, inter alia, under the influence of narratives, serve as a pattern for decision-making by the viewer/reader? It is necessary to this end to identify the relationship between the performative and the narrative (there are several types of these rela­tionships). To answer the above question, the genesis of narratives is considered, possible nar­rative–performative combinations analysed, and the effects of performatives on the formation of the intentional component of the narrative established. The findings suggest that each nar­rative contains at least one performative and that the narrative is based on the performative and contains a manipulative component.

This study describes and evaluates the performance of producing a pure Helium fraction from Helium extraction facility designed for cryogenic natural gas plants. A generic concept for obtaining a Helium pure fraction, which has relatively lower capital and operating costs should be provided. In order to achieve this objective, a new concept for obtaining a Helium pure fraction from a crude Helium fraction, is proposed based on simulations run under diverse process conditions regarding crude Helium gas’ temperature, pressure and composition. This concept is characterized by; reducing the plant safety requirements due to the extensive separation of combustible components, and compact layout of Helium extraction plant. Further re-purification is included in the subsequent Helium liquefaction step through selective adsorption, hence then increasing the purity of the Helium product and reducing the plant energy consumption required for liquefying Helium-rich fraction and the valuable Helium boil-off routed from the storage facility. The Nitrogen-rich fraction is routed to Nitrogen liquefaction installation. Liquid Nitrogen is generated within Helium recovery facility for liquid Helium shielding and container cooling. Surplus gaseous Nitrogen either can be liquefied and used within cryogenic natural gas plant as process coolant or be vented to atmosphere.
