Identification of a Ligand on the Wip1 Bacteriophage Highly Specific for a Receptor on Bacillus anthracis

2013

ABSTRACT Tectiviridae is a family of tailless bacteriophages with Gram-negative and Gram-positive hosts. The family model PRD1 and its close relatives all infect a broad range of enterobacteria by recognizing a plasmid-encoded conjugal transfer complex as a receptor. In contrast, tectiviruses with Gram-positive hosts are highly specific to only a few hosts within the same bacterial species. The cellular determinants that account for the observed specificity remain unknown. Here we present the genome sequence of Wip1, a tectivirus that infects the pathogen Bacillus anthracis . The Wip1 genome is related to other tectiviruses with Gram-positive hosts, notably, AP50, but displays some interest…

Construint la revolta. Política, comunicació i mobilització social en la gènesi de l'austriacisme valencià

2015

El dia 1 de novembre de l’any 1700 moria, sense fills, Carles II, rei d’Espanya. L’obertura del seu document testamentari, on es declarava hereu Felip de Borbó, nét del rei de França, va desfermar un conflicte internacional que, durant més d’una dècada, va convertir Europa en camp de batalla. Al Regne de València, com a la major part de territoris que formaven la Monarquia Hispànica, les últimes voluntats del difunt monarca van ser acceptades i Felip V va ser reconegut per les institucions com a rei. Aleshores, res no feia presagiar que, en menys de cinc anys, l’arxiduc Carles d’Àustria seria aclamat per centenars de valencians com a rei d’Espanya i que aquests no dubtarien a prendre les ar…

Puhummeko nyt rasismista?

2020

Rasismi-sanaan liittyy epävarmuutta siitä, mitä se on ja missä yhteyksissä sitä voi käyttää. Yksi syy hämmennykseen on se, että sanaa on opittu varomaan. Myös osa rasismintutkijoista käyttää tutkimuksessaan muita termejä välttyäkseen rasismi-sanan aiheuttamalta vastareaktiolta. Kun rasismia on ryhdytty korvaamaan ”turvallisemmilla” termeillä, niiden merkityssisällöt ovat alkaneet hämärtyä. Tutkimuskirjallisuudessa käytetään rinnakkain ja jopa samaa tarkoittavina syrjintää, toiseuttamista, ksenofobiaa, rodullistamista ja rasismia ilman, että termien välisiä merkityseroja useinkaan pohditaan tai avataan kunnolla. Sanahämmennyksen seurauksena rasismikeskustelua käydään tutkimuksessa – ja myös …

Pedro Gutiérrez Bueno (1743-1822) y las relaciones entre la química y la farmacia durante el último tercio del siglo XVIII

2001

This paper is part of a general research project on the role that chemistry played in transforming experimental pharmacology during nineteenth-century Spain. Within this general framework, this paper deals with the main characteristics of chemistry textbooks written by Pedro Gutiérrez Bueno (1745-1822), a pharmacist who taught chemistry in several institutions during the late eighteenth century. In an earlier paper, we have analysed the intended public of the first edition of Gutiérrez Bueno`s textbook. This paper deals with the changing institutional context in which the second edition was published. This issue is closely connected with substantial transformations in the relationship betwe…

Bernardine Evaristo’s The Emperor’s Babe: Re-narrating Roman Britannia, De-essentialising European History

2019

Bernardine Evaristo’s The Emperor’s Babe (2001) contributes to the imaginative disentanglement of the traditional British ethnicity-and-nation nexus and questions the related founding myth of racial purity by featuring the character of Zuleika, a young black woman who is born of Sudanese parents in Roman London. Through the depiction of Zuleika, Evaristo offers a subversive reshaping of some versions of the official British national history in the context of a wider revision of the European classical past. However, in spite of its temporal setting, Evaristo’s historical novel simultaneously engages with contemporary issues of gendered racialisation and national belonging. In its highly orch…

“This Racial Menace”?: Public Health, Venereal Disease and Maori in New Zealand, 1930–1947

2007

In 1939, Whakatane, on the remote east coast of the North Island of New Zealand, came to the attention of the New Zealand Department of Health as an area where syphilis was “suspected [to be] widespread”.1 This isolated part of the country was largely inhabited by Maori communities, and the revelation that venereal disease (VD) was so prevalent caught the Department by surprise, especially as a nationwide public health campaign against venereal disease had been in progress since 1917.2 In response, a comprehensive venereal disease campaign targeting Maori alone was developed––the earliest example of such a focus by the Department. This reaction highlighted what Dr Thomas Ritchie, Director o…

Ecohydrological adaptation of soils following land abandonment in a semi-arid environment

2010

Representative land use types were selected in southeast Spain to investigate the redistribution of soil water in relation to vegetation development and land abandonment.Simulated rainfall experiments were performed during 2 days on each of the four selected surfaces: ploughed, a 3-year fallow field, a 12-year abandoned field with shrubs and a semi-natural field with Stipa tenacissima tussocks. Each experiment consisted of five runs of artificial rain. Soil moisture dynamics were measured by time domain reflectometry (TDR), as well as runoff and ponding on the plot surface. Also the movement of the wetting front was measured after each run.On the ploughed field, ponding and local runoff wer…

Soil erosion after land abandonment in a semiarid environment of southeastern Spain

1997

Different soil units were selected in southeastern Spain to investigate the effects of land abandonment on soil erosion under semiarid conditions. The study sites selected were a cultivated field (bare), a 3‐yr‐abandoned field (herbs), a 10‐yr‐abandoned field (Artemisia herba‐alba Asso.), and two soil units covered with semi‐native (Stipa tena‐cissima L) and native (Pinus halepensis Miller) vegetation. Simulated rainfall measurements showed that the erosion and runoff increased after the land abandonment, but later erosion decreased owing to the influence of increasing vegetation. Runoff discharge (35%) and the erosion rates (334 g m2 h‐1) were high in the 3‐yr‐abandoned land in comparison …

The effect of patchy distribution ofStipa tenacissimaL. on runoff and erosion

1997

In south-east Spain, a semi-arid area,Stipa tenacissima(alphagrass) covers large natural and semi-natural areas with a mosaic of tussocks and bare zones. However, little knowledge exists about the influence of these patterns on runoff and erosion. In order to understand the hydrological and erosional behaviour of the vegetated (herbs andalphagrass) and bare zones, rainfall simulation experiments were carried out at three sites in south-east Spain. The experiments showed that surface runoff and erosion is negligible in the tussock and quite high in the bare areas. High infiltration rates and deep wetting fronts were measured in the vegetated patches, and lower infiltration rates and shallowe…
