Escritura colectiva como resistencia : el colectivo "Write like a girl"

"Write like a girl", parafraseo del ya clásico "Fight like a girl", anónimo y popular, acuñado por las feministas para dar a entender que las chicas también saben pelear. Sin embargo, no podemos dejar de preguntarnos: ¿qué sería hacer algo “como una chica"? Es a través del discurso que accedemos a la materialidad del cuerpo. Así, es en las palabras donde resignificamos nuestra identidad. Por ello, hablar de los cuerpos es una tarea urgente y conjunta. Lo colectivo, entonces, ofrece una mirada contracultural, pues se opone a la mirada patriarcal y ofrece un sistema colaborativo de organización en los márgenes. Se desvía de la tradicional búsqueda de legitimación, entendiendo que el rol del crítico y del canon siempre fueron los de un padre que alecciona. En su carácter performativo, ofrece otras maneras de circulación y propone y abre nuevos espacios de difusión y recepción, nuevas lecturas y nuevas críticas: vamos a la búsqueda de las genealogías de mujeres, de las que somos deudoras sin saberlo. Tal como plantea Laddaga (2006), estamos ante nuevos paradigmas que entienden al arte como un régimen práctico y proponen estéticas de la resistencia que buscan crear formas de convivencia mediante la creación de mundo comunes en las que, no importa el resultado, la obra pasa a ser el proceso. Bajo este concepto, el de régimen práctico de las artes, nos proponemos realizar una investigación de tipo cualitativa acerca de las acciones llevadas a cabo por el Colectivo durante los últimos 4 años, reflexionando sobre la propia práctica que incluye producción y organización, con el fin de entender los alcances reales de la misma.Fil: Colectivo “Write like a girl" .

Urochordate Histoincompatible Interactions Activate Vertebrate-Like Coagulation System Components

The colonial ascidian Botryllus schlosseri expresses a unique allorecognition system. When two histoincompatible Botryllus colonies come into direct contact, they develop an inflammatory-like rejection response. A surprising high number of vertebrates' coagulation genes and coagulation-related domains were disclosed in a cDNA library of differentially expressed sequence tags (ESTs), prepared for this allorejection process. Serine proteases, especially from the trypsin family, were highly represented among Botryllus library ortholgues and its “molecular function” gene ontology analysis. These, together with the built-up clot-like lesions in the interaction area, led us to further test whether a vertebrate-like clotting system participates in Botryllus innate immunity. Three morphologically distinct clot types (points of rejection; POR) were followed. We demonstrated the specific expression of nine coagulation orthologue transcripts in Botryllus rejection processes and effects of the anti-coagulant heparin on POR formation and heartbeats. In situ hybridization of fibrinogen and von Willebrand factor orthologues elucidated enhanced expression patterns specific to histoincompatible reactions as well as common expressions not augmented by innate immunity. Immunohistochemistry for fibrinogen revealed, in naïve and immune challenged colonies alike, specific antibody binding to a small population of Botryllus compartment cells. Altogether, molecular, physiological and morphological outcomes suggest the involvement of vertebrates-like coagulation elements in urochordate immunity, not assigned with vasculature injury

Late Triassic tectonic inversion in the upper Yangtze Block: insights from detrital zircon U–Pb geochronology from southwestern Sichuan Basin

The Sichuan Basin and the Songpan-Ganze terrane, separated by the Longmen Shan fold-and-thrust belt (the eastern margin of the Tibetan Plateau), are two main Triassic depositional centers, south of the Qinling-Dabie orogen. During the Middle – Late Triassic closure of the Paleo-Tethys Ocean the Sichuan Basin region, located at the western margin of the Yangtze Block, transitioned from a passive continental margin into a foreland basin. In the meantime, the Songpan-Granze terrane evolved from a marine turbidite basin into a fold-and-thrust belt. To understand if and how the regional sediment routing system adjusted to these tectonic changes, we monitored sediment provenance primarily by using detrital zircon U-Pb analyses of representative stratigraphic samples from the southwestern edge of the Sichuan Basin. Integration of the results with paleocurrent and published detrital zircon data from other parts of the basin identified a marked change in provenance. Early-Middle Triassic samples were dominated by Neoproterozoic (~700-900Ma) zircons sourced mainly from the northern Kangdian basement, whereas Late Triassic sandstones recorded a more diverse range of zircon ages, sourced from the Qinling, Longmen Shan and Songpan-Ganze terrane. This change reflects a major drainage adjustment in response to the Late Triassic closure of the Paleo-Tethys Ocean and significant shortening in the Longmen Shan thrust belt and the eastern Songpan-Ganze terrane. Further, by Late Triassic time, the uplifted northern Kangdian basement had subsided. Considering the eastward paleocurrent and depocenter geometry of the Upper Triassic deposits, subsidence of the northern Kangdian basement probably resulted from eastward shortening and loading of the Songpan-Ganze terrane over the western margin of the Yangtze Block in response to the Late Triassic collision between Yangtze Block, Yidun arc and Qiangtang terrane along the Ganze-Litang and Jinshajiang sutures

Search for pair production of heavy vector-like quarks decaying into high-p_{T} W bosons and top quarks in the lepton-plus-jets final state in pp collisions at s√=13 TeV with the ATLAS detector

A search is presented for the pair production of heavy vector-like B quarks, primarily targeting B quark decays into a W boson and a top quark. The search is based on 36.1 fb⁻¹ of pp collisions at s√=13 TeV recorded in 2015 and 2016 with the ATLAS detector at the CERN Large Hadron Collider. Data are analysed in the lepton-plus-jets final state, characterised by a high-transverse-momentum isolated electron or muon, large missing transverse momentum, and multiple jets, of which at least one is b-tagged. No significant deviation from the Standard Model expectation is observed. The 95% confidence level lower limit on the B mass is 1350 GeV assuming a 100% branching ratio to Wt. In the SU(2) singlet scenario, the lower mass limit is 1170 GeV. The 100% branching ratio limits are found to be also applicable to heavy vector-like X production, with charge +5/3, that decay into Wt. This search is also sensitive to a heavy vector-like B quark decaying into other final states (Zb and Hb) and thus mass limits on B production are set as a function of the decay branching ratios

New Developments in the World of Biomass Utilization

The economic competitiveness of cellulosic biofuels is highly dependent on feedstock cost, which constitutes 35–50% of the total fuel production cost, depending on geographical factors and equipment selection for harvesting, collecting, preprocessing, transporting, and handling the material. Consequently, feedstock cost and availability are the driving factors that influence near-term biorefinery locations and will largely control the rate at which this industry grows. Initial model-based supply scenarios postulate a dry feedstock supply system design case as a demonstration of the current state of technology. Based on this near-term design, advanced scenarios were developed to determine key cost barriers, needed supply improvements, and technology advancements to achieve long-term cost targets. Near-term supply systems will start by using current infrastructure and technologies and be individually designed for biorefineries using specific feedstock types and varieties based on local geographic conditions. However, as the industry develops, cost barriers are addressed, and risks associated with large scale biomass utilization are considered, the supply systems will incorporate advanced technologies that will eliminate downstream diversity and provide a uniform, tailored feedstock for multiple biorefineries located in different regions. This advanced supply system will utilize current handling infrastructure to move a quality controlled, desified, and stable cellulosic feedstocks to biorefineries as a commodity material similar to current grain and emerging wood commodities
