Foucault, pastoral power, and optics

2015

The article shows that in Foucault’s late 1970s and early 1980s analyses of pastoral, conductive power—most essentially in early and medieval Christianity—the issue of sight and visual perception recurs and occupies a crucial status. In Foucault’s discussion, these Christian relations of power, knowledge, and truth are attached with a surveying gaze that is both totalizing as well as individualizing, one that is mobilized by the thrust towards perfect visibility, transparency, and illumination of the subject turned into an object. The intention is also to develop Foucault’s analysis further, by demonstrating how Christian, providential government can be and actually has been detached from …

TANAMI monitoring of Centaurus A: The complex dynamics in the inner parsec of an extragalactic jet

2014

Centaurus A is the closest radio-loud active galaxy. Very Long Baseline Interferometry (VLBI) enables us to study the jet-counterjet system on milliarcsecond (mas) scales, providing essential information for jet emission and propagation models. We study the evolution of the central parsec jet structure of Cen A over 3.5 years. The proper motion analysis of individual jet components allows us to constrain jet formation and propagation and to test the proposed correlation of increased high energy flux with jet ejection events. Cen A is an exceptional laboratory for such detailed study as its proximity translates to unrivaled linear resolution, where 1 mas corresponds to 0.018 pc. The first 7 …

Kinetic power of quasars and statistical excess of MOJAVE superluminal motions

2012

The MOJAVE survey contains 101 quasars with a total of 354 observed radio components that are different from the radio cores, among which 95% move with apparent projected superluminal velocities with respect to the core, and 45% have projected velocities larger than 10c (with a maximum velocity 60c). Doppler boosting effects are analyzed to determine the statistics of the superluminal motions. We integrate over all possible values of the Lorentz factor the values of the kinetic energy corresponding to each component. The calculation of the mass in the ejection is carried out by assuming the minimum energy state. This kinetic energy is multiplied by the frequency at which the portions of the…

A relativistically smeared spectrum in the neutron star X-ray binary 4U 1705−44: looking at the inner accretion disc with X-ray spectroscopy

2009

Iron emission lines at 6.4-6.97 keV, identified with fluorescent Kalpha transitions, are among the strongest discrete features in the X-ray band. These are therefore one of the most powerful probes to infer the properties of the plasma in the innermost part of the accretion disc around a compact object. In this paper we present a recent XMM observation of the X-ray burster 4U 1705-44, where we clearly detect a relativistically smeared iron line at about 6.7 keV, testifying with high statistical significance that the line profile is distorted by high velocity motion in the accretion disc. As expected from disc reflection models, we also find a significant absorption edge at about 8.3 keV; th…

Comparative analysis of two paradigm bacteriophytochromes reveals opposite functionalities in two-component signaling

2021

Bacterial phytochrome photoreceptors usually belong to two-component signaling systems which transmit environmental stimuli to a response regulator through a histidine kinase domain. Phytochromes switch between red light-absorbing and far-red light-absorbing states. Despite exhibiting extensive structural responses during this transition, the model bacteriophytochrome from Deinococcus radiodurans (DrBphP) lacks detectable kinase activity. Here, we resolve this long-standing conundrum by comparatively analyzing the interactions and output activities of DrBphP and a bacteriophytochrome from Agrobacterium fabrum (Agp1). Whereas Agp1 acts as a conventional histidine kinase, we identify DrBphP a…

I RODITORI DI CAVA MONTICINO (BRISIGHELLA, RA)

2021

Rodents are the most abundant group of small mammals occurring in Brisighella deposits. They are represented by 12 species in total, among which 2 hamsters (Apocricetus cf. barrierei and Ruscinomys cf. lasallei), 2 dormice (Muscardinus sp. and Myomimus sp.), 1 porcupine (Hystrix (Hystrix) depereti), 2 sciurids (Atlantoxerus cf. rhodius and Hylopetes sp.) and 5 species of muridae (Apodemus cf. gudrunae, Centralomys benericettii, Occitanomys sp, Paraethomys meini and Stephanomys debruijni). This association suggests a relatively dry open environment, interrupted by forest environment with more or less dense underground.

I roditori sono il gruppo di micromammiferi più abbondante presente a Brisighella. Sono presenti 12 specie in totale: due cricetidi (Apocricetus cf. barrierei e Ruscinomys cf. lasallei) due gliridi (Muscardinus sp. e Myomimus sp.) un istrice (Hystrix (Hystrix) depereti) due sciuridi (Atlantoxerus cf. rhodius e Hylopetes sp.) e ben cinque specie di muridi (Apodemus cf. gudrunae Centralomys benericettii Occitanomys sp. Paraethomys meini e Stephanomys debruijni). Questa associazione suggerisce un ambiente aperto relativamente arido intervallato da spazi di foresta secca con sottobosco più o meno fitto.

We therefore questioned the existence and effect of current drought management strategies on the actual impacts and how drought is perceived by relevant stakeholders. Over 700 participants from 28 European countries provided insights into drought hazard and impact perception and current management strategies. The study concludes with an urgent need to collectively combat drought risk via a European macro-level drought governance approach.11.

Closely Related Archaeal Haloarcula hispanica Icosahedral Viruses HHIV-2 and SH1 Have Nonhomologous Genes Encoding Host Recognition Functions

2012

Studies on viral capsid architectures and coat protein folds have revealed the evolutionary lineages of viruses branching to all three domains of life. A widespread group of icosahedral tailless viruses, the PRD1-adenovirus lineage, was the first to be established. A double -barrel fold for a single major capsid protein is characteristic of these viruses. Similar viruses carrying genes coding for two major capsid proteins with a more complex structure, such as Thermus phage P23-77 and haloarchaeal virus SH1, have been isolated. Here, we studied the host range, life cycle, biochemical composition, and genomic sequence of a new isolate, Haloarcula hispanica icosahedral virus 2 (HHIV-2), which…
