Experiencing the Posthuman: the Cinematic Clone in the 21st Century

  • Carrasco Carrasco, Rocío|||0000-0001-7403-3954
The clone, especially in its audiovisual version, has often been treated as a marginalized being and its body understood as a repository of violence and pain, especially since its mere existence has traditionally been subjected to maintaining the integrity of the ‘original’ human body. This is visible in films in which we observe the figure of the clone treated in ways contrary to the critical posthumanism postulated by Braidotti, Ferrando or Vint, among others. The Island (2005), Never Let me Go (2010) or the animated series World of Tomorrow (2015, 2017, 2020) make us reflect on our responsibility toward the consequences of certain uses of biomechanical technology. A process of social denunciation is carried out through the emphasis that these films give to posthuman subjectivity, and thus these clones show their concerns and make viewers participants in their marginalized experience. Viewers see life from their perspective, we share their biological consciousness and their very existence leads us to reflection and denunciation

The Sanabria appinitic rocks and host migmatites form an unusual, non-peri-batholithic complex in which all the typical members of the appinite suite are present. It differs from most appinitic complexes in the deeper level of emplacement and the close temporal and spatial association with migmatites. Consequently, many in situ relationships that resulted from the invasion of mafic magma into a crustal anatectic zone are extremely well preserved. The complex shows unequivocal relations between members of the appinitic suite and between these and migmatites derived by anatexis of a gneissic formation (Ollo de Sapo gneiss). These relations point to derivation of monzodiorites and biotite diorites by hydrous basalt fractionation combined with fluid-assisted melting of the crustal rocks surrounding the appinitic intrusions. This hydrous basic magma may be derived from an enriched region of the mantle associated with subduction. Petrogenetic models have been tested using a combination of field relations and geochemical data. Despite the complexity of the processes involved, it is concluded that water played an important role in the petrogenesis of the intermediate and mafic magmas. Reaction between monzodiorite melts and the host migmatites was responsible for the generation of a range of intermediate rocks within the complex. The need for water to facilitate magma generation in both the mantle and the crust suggests that melting is linked with subduction. This interpretation has important implications because appinitic magmatism may be considered as indicative of subduction processes involved not only in the generation of the mafic end-members of the suite, but also in the generation of batholiths with which the appinitic rocks are spatially and temporally associated.

The stratigraphic basis of this work has allowed the use of larger foraminifers in the biostratigraphic characterisation of the new Shallow Benthic Zones (SBZ). This part of the volume presents a description of the sedimentary cycles formed by the transgressive-regressive systems of the Lutetian and Bartonian in the southeastern sector of the Ebro Foreland Basin. Concerning the Lutetian deposits studied in the Amer-Vic and Empordà areas, four sedimentary cycles have been characterised. The first and second are found within the Tavertet/Girona Limestone Formation (Reguant, 1967; Pallí, 1972), while the third and fourth cycles cover the Coll de Malla Marl Formation (Clavell et al., 1970), the Bracons Formation (Gich, 1969, 1972), the Banyoles Marl Formation (Almela and Ríos, 1943), and the Bellmunt Formation (Gich, 1969, 1972). In the Bartonian deposits studied in the Igualada area, two transgressive-regressive sedimentary cycles have been characterised in the Collbàs Formation (Ferrer, 1971), the Igualada Formation (Ferrer, 1971), and the Tossa Formation (Ferrer, 1971). The Shallow Benthic Zones (SBZs) recognised within the Lutetian are the following: SBZ 13, from the Early Lutetian, in the transgressive system of the first cycle; SBZ 14, from the Middle Lutetian, in the second cycle and the lower part of the transgressive system of the third cycle; SBZ 15, from the Middle Lutetian, in the remaining parts of the third system; SBZ 16, from the Late Lutetian, throughout the fourth cycle. The association of larger foraminifers in the first and second cycles of the Bartonian in the Igualada area has been used as the basis for the definition of SBZs 17 and 18 recognised in the Bartonian of the western Tethys.

The elastic scattering and inclusive α-particle yield for the 6He + 206Pb system at an incident energy of 18 MeV, just below the nominal Coulomb barrier, have been measured. The α-particle yield at forward angles is also reported. The data are analyzed by means of continuum-discretized coupled-channels, distorted wave Born approximation, and coupled reaction channels calculations. Couplings to the one-neutron- and two-neutron-transfer reactions are found to be able to account for most of the absorption in the entrance channel., This work was supported in part by Grant No. FPA2010-22131-C02-01 from the Spanish Ministry of Science.

We analyse here a wide sample of carbonaceous chondrites from historic falls (e.g. Allende, Cold Bokkeveld, Kainsaz, Leoville, Murchison, Murray, Orgueil and Tagish Lake) and from NASA Antarctic collection. With the analysis of these meteorites we want to get new clues on the role of aqueous alteration in promoting the reflectance spectra diversity evidenced in the most primitive chondrite groups. The selected meteorite specimens are a sample large enough to exemplify how laboratory reflectance spectra of rare groups of carbonaceous chondrites exhibit distinctive features that can be used to remotely characterize the spectra of primitive asteroids. Our spectra cover the full electromagnetic spectrum from 0.2 to 25 μm by using two spectrometers. First one is an ultraviolet (UV)–near-infrared (NIR) spectrometer that covers the 0.2–2 μm window, while the second one is an attenuated total reflectance infrared spectrometer covering the 2–25 μm window. In particular, laboratory analyses in the UV–NIR window allow obtaining absolute reflectance by using standardized measurement procedures. We obtained reflectance spectra of specimens belonging to the CI, CM, CV, CR, CO, CK, CH, R and CB groups of carbonaceous chondrites plus some ungrouped ones, and it allows identifying characteristic features and bands for each class, plus getting clues on the influence of parent body aqueous alteration. These laboratory spectra can be compared with the remote spectra of asteroids, but the effects of terrestrial alteration forming (oxy)hydroxides need to be considered., Current research was supported by the Spanish Ministry of Science and Innovation (project: AYA2011-26522) and CSIC (starting grant #201050I043).

Different lignocellulosic biomass sources were characterized energetically along a study period of two years in Huelva (southwestern region in Spain) for energy production. Then, the different kinds of lignocellulosic biomass obtained from these sources were evaluated and classified according to use, such as fuel for electric power generation in the area. The groupings of the average moisture content values and average gross heating values (over dry basis) of the samples analyzed were made based on the type of material, and for larger groups (with a significant dispersion of the gross heating values), the average values were estimated in subgroups or “characteristic groups.” A six-cluster scheme allowed us to classify the different groups of materials. The average gross heating values of the six different clusters (raw materials) showed significant similarities. It was observed that softwood and related materials typically have values in the region of 20.0 MJ/kg, and hardwood, such as that from Eucalyptus globulus, yields about 18.0 MJ/kg, whereas other deciduous plants (and their residues) give lower values., The authors are grateful for the FPU grant from the Spanish Ministry of Education.

Kinetic experiments based on the measurement of nitrogen evolution in the reaction of ethyl diazoacetate (N2CHCO2Et, EDA) and styrene or methanol catalyzed by the [IPrAu]+ core (IPr = 1,3-bis(diisopropylphenyl)imidazole-2-ylidene) have provided evidence that the transfer of the carbene group CHCO2Et to the substrate (styrene or methanol) takes place in the coordination sphere of Au(I) by means of an inner-sphere mechanism, in contrast to the generally accepted proposal of outer-sphere mechanisms for Au(I)-catalyzed reactions., Support for this work was provided by the MINECO (CTQ2014-52769-C3-1-R), and the Junta de Andalucía (P10- FQM-06292).
