A Numerical Method for the Analysis of Plane-Strain Forming Processes with Unilateral Constraints
1983
The Authors propose a numerical model for the solution of plane-strain forming processes, based on the linearization of the yield surface. This allows to employ the linear programming technique for the solution of the variational problem derived from the application of the upper-bound theorem. Such a model permits to take into account the unilateral constraints in a very simple way. Therefore it is well suited to solve a large class of problems, such as sheet forming, in which the unilateral constraints are often present.
Measure of a limestone weathering degree using Laser Scanner.
2013
The weathering degree of the building materials and natural stones is generally quantified as the decrement of some mechanical features that can be measured experimentally by means of compressive tests or point load tests in the laboratory or Schmidt hammer tests carried out in situ. Such destructive or damaging tests are unacceptable in case of cultural heritage since even small amounts of damage must be avoided. This work shows a correlation between Schmidt hammer rebound values and the reflectivity that is detected by means of terrestrial scanner laser; therefore it allows assessing the weathering degree of buildings or stones in situ. The results demonstrate that such an investigation c…
Canned Emotions. Effects of Genre and Audience Reaction on Emotions
2017
Laughter is said to be contagious. Maybe this is why TV stations often choose to add so-called canned laughter to their shows. Questionable as this practice may be, observers seem to like it. If such a simple manipulation, assumingly by inducing positive emotion, can change our attitudes toward the film, does the opposite manipulation work as well? Does a negative sound-track, such as screaming voices, have comparable effects in the opposite direction? We designed three experiments with a total of 110 participants to test whether scream-tracks have comparable effects on the evaluation of film sequences as do laugh-tracks. Experiment 1 showed segments of comedies, scary, and neutral films an…

Fluticasone furoate maintains epithelial homeostasis via leptin/leptin receptor pathway in nasal cells
2014
Leptin is involved in the lung epithelial homeostasis. Its role in the nasal tract is largely unknown. Allergic rhinitis (AR) is induced by the allergen exposure leading to consequential structural abnormalities in the nasal epithelium. Topical corticosteroids are recommended as first-line therapy in AR. Parietaria pollen is one of the most important allergenic sources in the southern Europe. In vitro, in human nasal epithelial cell line RPMI 2650, we aimed to determine whether allergen stimulation acts on leptin/leptin receptor pathway and how fluticasone furoate (FF) influences this pathway. The effects of the major allergen recombinant Par j 1 (rPar j 1), of FF, of leptin, and of TGF-b1 …
HSP27 controls GATA-1 protein level during erythroid cell differentiation.
2010
AbstractHeat shock protein 27 (HSP27) is a chaperone whose cellular expression increases in response to various stresses and protects the cell either by inhibiting apoptotic cell death or by promoting the ubiquitination and proteasomal degradation of specific proteins. Here, we show that globin transcription factor 1 (GATA-1) is a client protein of HSP27. In 2 models of erythroid differentiation; that is, in the human erythroleukemia cell line, K562 induced to differentiate into erythroid cells on hemin exposure and CD34+ human cells ex vivo driven to erythroid differentiation in liquid culture, depletion of HSP27 provokes an accumulation of GATA-1 and impairs terminal maturation.

Divisas o empresas históricas de damas. Algunos testimonios (siglos XV y XVI)
2019
ABSTRACT: Devices, badges or imprese, modalities of emblematics, were used by women between the 14th and 17th centuries, although less frequently than by men. This study analyses a little more than two dozen historical devices of ladies of the XVth and XVIth centuries from the perspective of emblematic genre theory. It deals with various aspects such as the structure, the personal involvement of the owners in the design of their devices, the purpose andmanners of displaying wit employed in their composition, etc., and concludes that there are no noticeable differences between women's devices and the masculine ones, except that the impreseof ladies crafted for special occasions (to display i…
Games that People Played in Early Modern Europa and the Emblem
2014
ABSTRACT: This study explores the existence and readership of board games in 16th and 17th century Europe of an emblematic nature. Such games may have derived from the conversation games featured in Baldassare Castiglione's The Book of the Courtier (1528), a work which includes a passage on emblems. In the Spanish tradition, the Filosofia cortesana moralizada (1587) of Alonso de Barros is a book of instructions on how to play this highly emblematic courtly board game, the board of which has unfortunately been lost. Some English emblems of the 17th century also include emblems likely based on Castiglione that depict the courtier as both warrior and scholar. Future studies need to clarify the…
