« Un inconnu dans la maison : l’enfant dans ¿ Quién puede matar a un niño ? (Narciso Ibáñez Serrador, 1974) »

2008

This article deals with ¿Quién puede matar a un niño? directed by Narciso Ibáñez Serrador, more famous thanks to his TV film series Historias para no dormir. In this film, children use to play an essential part in the development of a pure fantastic style (in Todorov’s terms), i.e. based on the irruption of unexplainable elements inside a perfectly normal realistic context. As some critics as Rosset have pointed out, the feeling of anguish does arise from such a realistic context, from that otherness within the child, the human being we are more reluctant to fear, the one we hardly view with suspicion Este artículo trata de la obra de Narciso Ibáñez Serrador y, en particular, de uno de sus …

Laser fluence, repetition rate and pulse duration effects on paint ablation

2006

Abstract The efficiency (mm3/(J pulse)) of laser ablation of paint was investigated with nanosecond pulsed Nd:YAG lasers (λ = 532 nm) as a function of the following laser beam parameters: pulse repetition rate (1–10,000 Hz), laser fluence (0.1–5 J/cm2) and pulse duration (5 ns and 100 ns). In our study, the best ablation efficiency (η ≅ 0.3 mm3/J) was obtained with the highest repetition rate (10 kHz) at the fluence F = 1.5 J/cm2. This ablation efficiency can be associated with heat accumulation at high repetition rate, which leads to the ablation threshold decrease. Despite the low thermal diffusivity and the low optical absorption of the paint (thermal confinement regime), the ablation th…

Thiazole Analogues of the Marine Alkaloid Nortopsentin as Inhibitors of Bacterial Biofilm Formation

2020

Anti-virulence strategy is currently considered a promising approach to overcome the global threat of the antibiotic resistance. Among different bacterial virulence factors, the biofilm formation is recognized as one of the most relevant. Considering the high and growing percentage of multi-drug resistant infections that are biofilm-mediated, new therapeutic agents capable of counteracting the formation of biofilms are urgently required. In this scenario, a new series of 18 thiazole derivatives was efficiently synthesized and evaluated for its ability to inhibit biofilm formation against the Gram-positive bacterial reference strains Staphylococcus aureus ATCC 25923 and S. aureus ATCC 6538 a…

Analyse du caractère dynamique des recommandations dans l'industrie cinématographique : le cas des franchises de films

2016

The release of motion picture sequels by studios led to the emergence of interaction effects between sequels over the time and in consequence altering models predicting the box office. If some scholars have examined these interaction effects, they were limited to the box office revenues. The paper proposes an extension of the interaction effects to third-party recommendations. The results – covering 123 sequels – demonstrate the dynamic and persistent nature of the recommendations.

Effect of the extensional flow on the properties of oriented nanocomposite films for twist wrapping

2011

In this study, we examined the mechanical behavior of nanocomposite films based on polyethylene (PE) and pristine PE films. The films were prepared by film blowing and were then cold-drawn at low temperature. The experimental results show that cold drawing significantly enhanced the orientation; with increasing draw ratio (DR), the elastic modulus and tensile strength of the PE films strongly increased, particularly in the presence of the organoclay. To obtain polymeric films suitable for twist wrapping, the films must be sufficiently stiff so that no shrinkage or elastic recovery occur during or after twisting. The elongation at break and the yield strain sharply decreased with orientation…

Patterning of supported gold monolayers via chemical lift-off lithography

2017

The supported monolayer of Au that accompanies alkanethiolate molecules removed by polymer stamps during chemical lift-off lithography is a scarcely studied hybrid material. We show that these Au–alkanethiolate layers on poly(dimethylsiloxane) (PDMS) are transparent, functional, hybrid interfaces that can be patterned over nanometer, micrometer, and millimeter length scales. Unlike other ultrathin Au films and nanoparticles, lifted-off Au–alkanethiolate thin films lack a measurable optical signature. We therefore devised fabrication, characterization, and simulation strategies by which to interrogate the nanoscale structure, chemical functionality, stoichiometry, and spectral signature of t…

Regulation of type 1 fimbriae synthesis and biofilm formation by the transcriptional regulator LrhA of Escherichia coli

2005

Type 1 fimbriae ofEscherichia colifacilitate attachment to the host mucosa and promote biofilm formation on abiotic surfaces. The transcriptional regulator LrhA, which is known as a repressor of flagellar, motility and chemotaxis genes, regulates biofilm formation and expression of type 1 fimbriae. Whole-genome expression profiling revealed that inactivation oflrhAresults in an increased expression of structural components of type 1 fimbriae.In vitro, LrhA bound to the promoter regions of the twofimrecombinases (FimB and FimE) that catalyse the inversion of thefimApromoter, and to the invertible element itself.

In the 21st century alone there have already been released plenty of computer-animated comedy-adventure cartoons that have become blockbusters in a very short time. America-based animation studios, such as the worlds oldest Walt Disney Animation Studios (1934), Pixar Animation Studios, DreamWorks Animation, Blue Sky Studios, or the most-recently established Illumination Entertainment (2007), have all been entertaining not only children themselves, but whole generations of viewers, including those childrens parents (e.g. the author of this article), grandparents, and great grandparents as well. Titles such as Shrek (2001), Ice Age (2002), Finding Nemo (2003), Tire Lion King III - Hakuna Mata…
