Le photogramme est, au cinéma, la plus petite unité de prise de vue. Image fixe, unité élémentaire du film, le photogramme forme la cellule figée d’un mouvement qui se reconstitue sous l’effet d’un défilement réglé (24 photogrammes/seconde) par le dispositif technique du cinéma. Image paradoxale en ce qu’elle reste invisible au spectateur malgré sa force iconique, le photogramme trouve cependant, dans le flux qui le conduit insensiblement à la disparition, certaines zones de visibilité qui en révèlent le caractère à la fois fragile et intensif. Nous allons donc envisager certaines pratiques ou certains usages du photogramme cinématographique, tout en essayant de dégager, au départ de ces pratiques, les éléments d’une théorie du photogramme, que Roland Barthes et Sylvie Pierre appelaient déjà de leurs vœux. Des protos-photogrammes et de leur usage scientifique chez Muybridge et Marey, aux usages artistiques contemporains, en passant par des pratiques publicitaires, promotionnelles ou analytiques, nous allons voir que le photogramme reste un objet singulier.

We study retirement incentives with an augmented reduced form option value model à la Stock and Wise (1990). We propose methodological extensions to better reflect the respective incentives faced by singles and couples. Our results show that a more comprehensive modelling of couples’ incentives leads to very different patterns of retirement incentives – particularly for women. We apply the new indicators to data from the Survey of Health, Ageing and retirement in Europe (SHARE) in Belgium and find two key results. First, contrary to several previous studies, we obtain a positive signed income effects. Second, we find very different retirement incentives for men and women, with little flexibility in the retirement decision for men and substantially more flexibility for women as a function of financial incentive and household composition.

Supplementation of post-weaning diets with exogenous enzymes has been suggested to control post-weaning syndrome, by compensating for the under-developed endogenous enzyme secretory capacity and increasing nutrient digestibility in newly weaned pigs. The effect of in-feed enzymes in improving gut maturation, growth and/or health in weaned piglets is not always consistent. A systematic review and a meta-analysis were therefore conducted to determine which exogenous enzymes are most consistent in improving piglet growth and digestibility when supplemented to post-weaning diets. The mean difference effect of enzyme supplementation on growth and digestibility of dry matter (DM), gross energy (GE), crude protein (CP), and P digestibility was calculated for each study and this was used as the effect size estimate in the meta-analysis. The impact of feed enzyme supplementation on intestinal health and bone mineralization was also discussed where information was available in the literature. From a total of 90 studies included in the metaanalysis, G:F was improved in 55, remained un-changed in 28 and deteriorated in 7, in response to enzyme supplementation. Average daily gain, average daily feed intake (ADFI) and G:F was improved when phytase was supplemented in the diet. Phosphorous digestibility was increased with phytase supplementation while GE digestibility was reduced. Dietary phytase supplementation increased bone mineralization in pigs fed diets with a reduced Pcontent. Supplementation with multi-enzyme complexes increased DM and CP digestibility. In conclusion, the most consistent improvement in piglet growth, P digestibility and bone mineralization were found due to exogenous phytase supplementation. Supplementation with xylanase alone or in combination with β-glucanase had inconsistent effects on piglet growth and nutrient digestibility. The most consistent improvements in growth and nutrient digestibility due to supplementation with multi-enzymes complexes were found when mannanase and/or protease were included in the complex.

In the last two decades, wavelet bases and associated methodologies have become quite important in many domains, such as signal and image processing, harmonic analysis, statistics, and so on. More recently, they also turn out to be quite useful in the probabilistic framework of stochastic processes, in which, among other things, they allow to obtain fine results concerning erratic sample paths behavior. The goal of our article is to derive a result, related with zeros of continuous compactly supported mother wavelets, which is useful in this probabilistic framework. More precisely, let $\psi$ be any arbitrary such wavelet; we show that being given an arbitrary point $x_0\in\R$ there always exists at least one integer $k_{x_0}\in\Z$ such that $\psi(x_0-k_{x_0}) \neq 0$.

In recent years, inclusive design (a.k.a. universal design or design for all) is one of the developed approaches which aim to consider the diverse human abilities and conditions in the design process. As defined by the European Institute for Design and Disability (EIDD) ‘design for all’ is designing for diversity, social inclusion and equality. Considering the social and demographic changes in the 21st century, which include an international movement towards social inclusion and more specifically the rights of disabled people, an inclusive approach is turning into a necessity for today’s diverse and ageing society. In the case of architectural and urban heritage, the disabled people or in better words those with diverse sensory, mental or mobility abilities who differ from the general public, have the right to experience, interact with, and engage with heritage and its values. As part of an extensive interdisciplinary research on inclusive approaches to built heritage values, which connects the fields of architecture, history, conservation, inclusive design, and digital humanities, this paper investigates the potentials of incorporating digital tools and techniques in the different aspects of this research. The extensive study involves communication between researchers, relevant professional experts, and the historic built environment with the target community of disabled people and in this paper, the digital means to facilitate these interactions have been studied. As a step towards answering the question ‘what are suitable methods and tools for facilitating and acquiring insight into diversely abled people’s engagement with and understanding of architectural heritage and its values?’, it more specifically focuses on the interaction of the disabled people with the historic architecture and urban spaces. Additionally, in a more general approach, by linking the fields of digital humanities and architectural research, the existing tools for the different stages of research ranging from data collection and storage, data analysis, and dissemination are explored. By conducting and elaborating relevant research examples, this study shows how incorporating digital tools and techniques derived from Digital Humanities - such as retrieving data through APIs, textual analysis, creating and querying databases, and data visualization - can facilitate research in the field of architecture and built heritage. Moreover, in studying the relation between disability and the historic built environment, it indicates that acquiring knowledge on the potentials in practical digital tools for disabled people’s interaction with the built heritage, can have a significant impact on the research approach and findings. As for an inclusive approach to built heritage, the disabled people can be taken into account with their prospective extended digital abilities. Hence in today’s digital world, integrating the digital tools and technologies in architectural heritage research is not only a necessary practical mean for conducting research, but can also impact the theoretical approach, allowing to carry out extensive and innovative research in an efficient manner.

Even if insect pest populations can be reduced by increasing plant diversity through intercropping, natural enemies are not always favored in such systems. Alternatively, semiochemical substances have been tested to enhance biological control, with inconsistent results. Combining both strategies can be an interesting way to maximize pest control. In this work, a 2-year setup involving wheat–pea strip intercropping combined with the release of E-b-farnesene (EBF) or methyl salicylate (MeSA) was tested as a push–pull strategy to simultaneously repel aphids and attract beneficials. Two types of slow-release formulation (i.e., oil and alginate beads) containing EBF or MeSA were deployed with the intercropping. The abundance of aphids was significantly decreased, while hoverfly larvae and mummified aphids increased on both pea plants and wheat tillers by the release of oil-formulated EBF and MeSA. The proportion parasitism of the aphid-parasitism rate [mummies/(aphids + mummies)] was also increased by treating both crops in both years. Releasing EBF through oil rather than alginate beads proved significantly better for attracting natural enemies and reducing aphids. Aphids were negatively correlated with the density of hoverflies (both adults and larvae) and numbers of mummies. All these results showed that combining intercropping with the release of EBF or MeSA formulated in oil can significantly reduce aphid density and attract their natural enemies. Therefore, the combination of both strategies could help farmers reduce the use of insecticides. [less ▲]

A nitrogen (N) balance digestion trial was conducted to determine the protein requirement of collared peccaries (Pecari tajacu). In a 4 × 4 Latin square design, four captive adult male peccaries were fed four isoenergy diets containing four different levels of N (11.7, 16.3, 22.8, and 26.7 g N/kg of dry matter—DM). After 15 days of adaptation, a total collection of feces and urine was carried out for five consecutive days. Regression analyses between N intake and N in feces and urine allowed to calculate the metabolic fecal nitrogen (MFN = 2.3 g N/kg of dry matter intake—DMI) and daily endogenous urinary N (EUN = 185 mg N/kg0.75). Likewise, by regression analyses between consumption of nitrogen and the nitrogen balance (NB = N ingested − N excreted, mg N/kg0.75), a daily requirement of 514 mg N/kg0.75 was calculated. Therefore, if food intake is unrestricted, collared peccaries require a minimumin their diet of about 5.4% crude protein on DM basis. These values are almost as low as those found for browsing and frugivorous wild ruminants, which reinforce the proposition that peccaries’ digestive physiology is nearer to that of domestic and wild ruminants than domestic pigs. This relatively low protein requirement of collared peccary and its great ability to digest protein reveal the relevance of the forestomach for the species on nitrogen/protein metabolism and allow the use of diets with lower crude protein levels than the commercial ones used for the domestic pig, which reduces feed costs.

This paper presents a novel search algorithm using time-domain simulations to identify plausible N-k contingencies endangering voltage stability. Starting from an initial list of disturbances, progressively more severe contingencies are investigated. After simulation of a N-k contingency, the simulation results are assessed. If the system response is unstable, a plausible harmful contingency sequence has been found. Otherwise, components affected by the contingencies are considered as candidate next event leading to N-(k+1) contingencies. This implicitly takes into account hidden failures of component protections. The performance of the proposed search algorithm is compared to a brute-force algorithm and demonstrated on the IEEE Nordic test system. [less ▲]

Located in the 'inner periphery' of Neapolitan historic center, at the foot of Capodimonte Park, historically the urban fabric of San Carlo Arena district eastern area has developed around two architectural complexes: Santa Maria dei Miracoli and Santa Maria degli Angeli alle Croci, for a long time aggregation places for local people. In addition, the ‘lava dei Vergini’ phenomenon, which periodically flooded the area outside the ancient city walls and the ‘for a via’ street (Via Foria), created optimal conditions for tuff extraction, used for local construction. In the past, physical features, such as the irregularity of the hilly area modeled by natural agents, the presence of several underground quarries, the grandeur of remarkable architectural presence, the numerous alleys in a heavily layered historical fabric, and the peculiarities of the social life that took place beyond Foria, have been a source of inspiration for several and also internationally renowned artists. The original identity of the ancient outer suburb, born from progressive expansions of the neighboring villages outside the city walls, is still marked. The closing elements that caracterize the architecture - in particular building fronts -, reflect its inhabitants attitudes and daily life. In this historic urban landscape 'shred’, this closure - despite the direct proximity to the adjacent old town and several, but not easily accessible, panoramic views of part of Naples Bay - continues to be one of the main identifying characters of the area. Although, for many centuries, this has allowed the 'spirit of places’ conservation, it has been transformed into a voluntary closure against the legality, which led to today serious state of neglect and social decay. Sometimes it is possible to find an excessive and illegal man-soil interaction, and unlawful activities influence and define some features of historical buildings in the area. However, for some years the local population has become aware of the existing problems by operating in a more concrete way, through different kinds of associations and volunteer that try to face the territory needs and emergencies. The goal is the elaboration of an update overview of the existing dynamics in this part of urban tissue and the identification of elements to take into account for possible enhancement perspectives in respect of an identity between invariant and processing factors.
