Aerosol optical characteristics from a summer campaign in an urban coastal Mediterranean area

2001

The authors present a preliminary study of some optical properties of atmospheric aerosols over the area of Valencia, Spain, a coastal Mediterranean city. Measurements of spectral direct irradiance in the 300-1100 nm range were taken simultaneously at three sites: rural-continental, rural-coastal, and urban-coastal, all located within a 50 km radius of the city of Valencia. The irradiance measurements were obtained using three Li-cor 1800 spectroradiometers provided with radiance limiting tubes with field of views (FOVs) of 4.7/spl deg/. The measurements were made under clear sky conditions during a field campaign carried out in the summer of 1998. In order to avoid the uncertainties associ…

Reconstructing Bronze Age diets and farming strategies at the early Bronze Age sites of La Bastida and Gatas (southeast Iberia) using stable isotope …

2020

The El Argar society of the Bronze Age in the southeast of the Iberian Peninsula (2200–1550 cal BCE) was among the first complex societies in Europe. Its economy was based on cereal cultivation and metallurgy, it was organized hierarchically, and successively expanded its territory. Most of the monumentally fortified settlements lay on steeply sloped mountains, separated by fertile plains, and allowed optimal control of the area. Here, we explore El Argar human diets, animal husbandry strategies, and food webs using stable carbon and nitrogen isotope analysis of charred cereal grains as well as human and animal bone collagen. The sample comprised 75 human individuals from the sites of La Ba…

Anomalous temperature dependence of the IR spectrum of polyalanine

1997

Abstract We have studied the temperature dependence of the infrared spectra of acetanilide (ACN), tryptophan–(alanine) 15 , and tyrosine–(alanine) 15 . No sidebands of the amide-I vibration were observed in the polypeptides, but two anomalous sidebands of the NH stretch with a similar temperature dependence as that of the anomalous amide-I vibrational mode at 1650 cm −1 of crystalline ACN were detected. Fermi resonance combined with the appearance of a red-shifted sideband of NH stretch through coupling to lattice modes seems to explain this band structure. Observations are indicative of excitons that may occur in polypeptides as well as in single crystals of ACN.

Raconter ses lectures, se raconter : plaisir de lire, identité et émancipation chez Alison Bechdel

2017

National audience; Cette communication interroge l’importance donnée aux liens entre plaisir de lire et identité (en particulier identité lesbienne) dans les récits autobiographiques d’Alison Bechdel. Celle-ci met en scène une première opposition entre les lectures d’enfance, caractérisée par l’immersion narrative, et les lectures légitimes que son père tente de lui imposer à mesure qu’elle grandit, avec une injonction à lire qu’elle finit par intérioriser. Cette opposition prend une valeur plus directement identitaire lorsque la lecture obligatoire de Ulysses à l’université est systématiquement opposée à la lecture d’un corpus varié d’œuvres gays et lesbiennes au moment de l’éveil politiqu…

Penser la frontière entre essai et autobiographie à partir de la bande dessinée. Are You My Mother? d'Alison Bechdel

2018

Based on Alison Bechdel's autobiographical essay Are You My Mother?, this article is a discussion on two boundaries of the essay : a generic boundary between essay and autobiography, questioned by the possibility of autobiographical essay, and an intermedial boundary challenged by the development of graphic essays in comics. Are You My Mother? is a self-reflexive autobiographical work which describes the author's discovery of psychoanalysis and deals at the same time with mother-child relationships and the continuity between novel writing, autobiography and psychoanalysis, thus articulating autobiographical material and general thoughts. The book can be described in particular as a consiste…

Karyotype Abnormalities in a Variant Chinese Hamster Cell Line Resistant to Methyl Methanesulphonate

2004

A variant cell population, isolated from V79-CI 3 Chinese hamster cells after two consecutive treatments with methyl methanesulphonate (MMS), was found to be highly resistant to killing by this alkylating agent. The resistant cell line was cytogenetically characterized both by the presence of a stable translocation involving metacentric chromosome 2 and acrocentric chromosome 6 and by a supernumerary chromosome originated by the duplication of a small telocentric chromosome. This cell population also showed a transient transformed phenotype, seen as formation of transformed foci containing cells with high chromosomes counts and multiple chromosomal aberrations. As MMS-resistance and karyoty…
