No full textRoma, Piazzale Ipponio, scavi delle Metropolitana C per la stazione Amba Aradam-Ipponio. Ceramiche fini, lucerne e anfore dalla dismissione di un condotto fognario dall’ex caserma adrianea
No full textThis paper focuses on the wares (fine wares, lamps and amphora) recovered from a sewer at the military complex discovered in Rome during the excavations for the metro Line C at the Amba Aradam station. The good state of preservation of the ce-ramics from this deposit suggests they were likely in use when they were dumped into the channel of the sewer. Accordingly, this assemblage offers an essential opportunity for a better understanding of the material culture circulating within Rome in the last decades of the 3rd century, which is a phase that is underrepresented archaeologically
Analysis of drivers for solving facility layout problems: Literature review
No full textFacility layout problems have a significant impact on the productivity and efficiency of the manufacturing systems. Generally, layout problems deal with the optimization of facility space and locations (e. g. machines, departments) and are oriented to optimize the system's performance within the facility space. Many research works discussed facility layout problems, and there are several literature reviews classified the problems, characteristics, solution methods, and mathematical models. In this paper, different aspects closely related to layout problem solutions and decision making are analyzed and reviewed. These aspects are organized as layout drivers: enabling technologies, tools and techniques, manufacturing systems, and supporting factors. Analyzing these four layout drivers will lead to suggest new ideas for optimizing the solution and obtaining robust and sustainable facility layout/re-layout design through integrating the industrial information. This review paper illustrates the trends, gaps, challenges and suggests some recommendations; the present analysis shall guide interested researchers and practitioners for integrating research works and developing new perspectives for future facility layout problem solutions and layout designs
Altérités poétiques d’un récit de vie. Parabole du failli de Lyonel Trouillot
No full textDans Parabole du failli (2013), Lyonel Trouillot rend hommage au célèbre comédien haïtien Karl Marcel Casséus, disparu en 1997. Dans ce récit qui concilie trois genres (le roman, la notice nécrologique et la poésie), l’auteur tente de circonscrire l’énigme de la vie de Pedro, personnage principal de la fiction, un comédien connu écrivant des poèmes en secret. Trois écritures conversent et se complètent pour raconter une même histoire, toutes assorties d’un discours métafictionnel interrogeant les choix d’écritures au sein de l’entreprise biographique ainsi que la part et les effets possibles de chacune d’entre elles dans la figuration d’un individu, l’historicisation d’une expérience et la fictionnalisation d’une vie. Au-delà du portrait empirique de l’artiste et du récit de la vie de Pedro, ce qui advient dans Parabole du failli c’est l’aventure poétique elle-même comme objet essentiel d’une entreprise biographique totale où se croisent le destin d’un poète et celui d’un roman, où s’entrelacent la trajectoire d’une existence et le parcours d’une écriture, tous subsumés par la poésie.In Parabole du failli (2013), Lyonel Trouillot pays tribute to the famous Haitian actor Karl Marcel Casséus, who died in 1997. Blending together novel, obituary and poetry, the author attempts to delineate the enigmatic life of the main character, Pedro, an acclaimed actor who writes poetry in secret. Not only do the three genres merge and complement each other within the telling of a single story, they are supplemented by a metafictional discourse that questions the choice of writing style for biography, for the portrayal of an individual, for the historicization of an experience, and for the fictionalization of a life. Beyond the empirical portrait of the artist and Pedro’s life story, what happens in Parabole du failli is that poetry becomes the essential object of a complete biography where the fate of a poet intersects with the outcome of a novel, where the paths of existence and of writing intertwine within the poetic adventure itself

In vitro treatment of monocytes with 8-methoxypsolaren and ultraviolet A light induces dendritic cells with a tolerogenic phenotype
No full textExtracorporeal photopheresis (ECP) has been considered an efficient dendritic cell (DC) therapy, used for treating both T cell malignancy, as well as T cell-mediated diseases. During the ECP procedure leucocytes are exposed to photoactivable agent 8-methoxypsolaren (8-MOP) and ultraviolet (UV) A radiation (PUVA) prior to reinfusion. Despite its clinical efficacy the mechanism of action remains elusive. As it has been reported that ECP might promote the differentiation of monocytes into immature DCs, we investigated the effects of UVA light (2 J/cm(2)) and 8-MOP (100 ng/ml) on in vitro monocyte-to-DC differentiation from normal donors. DCs were generated from human purified CD14(+) cells. Because monocytes are killed by PUVA and taking into account that only 5-10% of circulating mononuclear cells are exposed to PUVA during the ECP procedure, we developed an assay in which 10% of PUVA-treated monocytes were co-cultured with untreated monocytes. We first demonstrate that the presence of 10% apoptotic cells and monocyte activation were not enough to induce monocyte differentiation into DCs. Adding cytokines to our culture system, we obtained immature DCs characterized by significantly higher phagocytic activity and human leucocyte antigen D-related (HLA-DR) expression. These DCs preserved the capacity to be activated by lipopolysaccharide, but showed a reduced capacity to induce allogeneic T cell proliferation when first co-cultured with 10% of PUVA-treated cells. Our experimental design provides a novel insight into the real action of 8-MOP and UVA light on dendritic cell biology, suggesting an additional mechanism by which 8-MOP and UVA light exposure may influence immune responses
Mercury Detection in Novel Foods by a Smart Pocket Sensor
No full textMercury is one of the most well-known toxic contaminants of natural and anthropogenic origin in aquatic ecosystems that can bioaccumulate in vegetal and animal organisms. In this work, we propose a smart detection system for Hg(II) ions by square wave anodic stripping voltammetry at nanocomposite graphite screen-printed electrodes, as an analytical tool to be applied in food quality control. The nanocomposite surfaces were obtained by the modification of screen-printed graphite electrodes with poly(l-aspartic acid) and gold nanoparticles and were characterized by means of electrochemical techniques. An exhaustive study of the experimental conditions involved both in the electropolymerization and in the voltammetric stripping measurements was addressed to develop a reliable method capable of measuring Hg(II) concentration in the low mu g/L range, both in conventional and drop configurations. The sensor was integrated in a smart setup, comprising a Sensit Smart pocket instrument connected to a smartphone, thus proving its applicability for in situ analysis due to its cost-effectiveness. The analytical significance of the developed sensor was assessed by detecting Hg(II) in novel food samples.imag
