Exploratory nuclear microprobe data visualisation using 3- and 4-dimensional biological volume rendering tools
2007
Abstract The emergence of Confocal Microscopy (CM) and Atomic Force Microscopy (AFM) as everyday tools in cellular level biology has stimulated development of 3D data visualisation software. Conventional 2-dimensional images of cell (optical) sections obtained in a transmission electron or optical microscopes and more sophisticated multidimensional imaging methods require processing software capable of 3D rendering and mathematically transforming data in 3-, 4-, or more dimensions. The richness of data obtained from the different nuclear microscopy imaging techniques and often parallel information channels (X-ray, secondary electron, Scanning Transmission Ion Microscopy) is often not obviou…
Madness (about) seeing: dalla costruzione sociale del visuale alla costruzione visuale del sociale
2017
La cultura che siamo soliti definire come “occidentale” possiede nell’oculocentrismo, come altre, più di altre, uno dei suoi tratti maggiormente distintivi. Individuato, tra gli altri, il senso della vista come canale privilegiato per relazionarsi con il mondo, l’uomo occidentale ha dato origine ad un’operazione di trasfigurazione del reale in termini visivi che lo ha condotto, in tempi recenti, ad identificarsi con gli oggetti che tale processo ha messo al mondo; da più parti, infatti, ci viene detto che viviamo nella (non meglio definita) “società delle immagini”. Subito dopo aver analizzato il luogo e il tempo in cui la preferenza per il vedere ha piantato le proprie solidissime e rizoma…
A putative social chemosignal elicits faster cortical responses than perceptually similar odorants.
2006
Social chemosignals, so-called pheromones, have recently attracted much attention in that effects on women's psychophysiology and cortical processing have been reported. We here tested the hypothesis that the human brain would process a putative social chemosignal, the endogenous steroid endrostadienone, faster than other odorants with perceptually matched intensity and hedonic characteristics. Chemosensory event-related potentials (ERP) were recorded in healthy women. ERP analyses indicate that androstadienone was processed significantly faster than the control odorants. Androstadienone elicited shorter latencies for all recorded ERP components but most so for the late positivity. This fin…
Predicting the environmental suitability for onchocerciasis in Africa as an aid to elimination planning
2021
Recent evidence suggests that, in some foci, elimination of onchocerciasis from Africa may be feasible with mass drug administration (MDA) of ivermectin. To achieve continental elimination of transmission, mapping surveys will need to be conducted across all implementation units (IUs) for which endemicity status is currently unknown. Using boosted regression tree models with optimised hyperparameter selection, we estimated environmental suitability for onchocerciasis at the 5 × 5-km resolution across Africa. In order to classify IUs that include locations that are environmentally suitable, we used receiver operating characteristic (ROC) analysis to identify an optimal threshold for suitabil…
Visualization practices in Scandinavian newsrooms : a qualitative study
2017
The visualization of numeric data is becoming an important element in journalism, and new tools and platforms make the development of data visualization in the news discourse accelerate. In this paper we present an interview study investigating this development in Scandinavian newsrooms. Editorial leaders, data journalists, graphic designers, and developers in 10 major news organizations in Norway, Sweden and Denmark inform the study on a range of issues concerning visual practices and experiences in the newsrooms. Elements of tension are revealed on issues concerning the role and effect of complex, exploratory data visualizations and concerning the role of ordinary journalists in the produ…
Effect of even and odd-order aberrations on the accommodation response
2017
Aim To investigate the potential effect that odd and even-order monochromatic aberrations may have on the accommodation response of the human eye. Methods Eight healthy subjects with astigmatism below 1 D, best corrected visual acuity 20/20 or better and normal findings in an ophthalmic examination were enrolled. An adaptive optics system was used in order to measure the accommodation response of the subjects' eyes under different conditions: with the natural aberrations being present, and with the odd and even-order aberrations being corrected. Three measurements of accommodation response were monocularly acquired at accommodation demands ranging from 0 to 4 D (0.5 D step). Results The acc…
The visual principle and the correlation between teaching of the Catholic religion and art education in Polish school
2017
Contemporary culture – as already noted – is becoming more and more visual. Contemporary catechesis, referring to its rich, centuries-long experience, should also use different types of images. The first part of this article presents the visual principle as one of basic educating principles, and the second part presents the correlation between the teaching of Catholic religion, and art education in Polish schools. One specific example of using religious painting are in textbooks. Masterpieces of painting, created during centuries and expressing particular desires of their creators, still remain an important inspiration, among others, to the religious search. Faith, though strongly anchored …
Los <i>Padres de la Iglesia</i> de Joaquín Oliet y la obra de Francisco de Goya
2008
The painter from Castellón, Joaquin Oliet Cruellas, carried out prolific mural decorations for various churches in Valencia, Alicante and Castellón in which his intense visual culture is evident. Especially interesting are the series of Fathers of the Latin Church painted for several of these churches, which display, with variants, compositions identical to those attributed to Francisco de Goya in Calatayud, Muel and Remolinos.<br><br>El pintor castellonense Joaquín Oliet Cruella realizó para diversas parroquias valencianas, castellonenses y alicantinas una prolífica decoración mural, en la que es palpable una intensa cultura visual.

La planificación del paisaje en la Comunidad Valenciana: análisis de la calidad y fragilidad visual
2007
La calidad y fragilidad visual del paisaje adquiere relevancia con el objeto de la gestión en el marco de la planificación del paisaje y Se pone en evidencia espacialmente su nueva dimensión jurídica en la ordenación del territorio en la Comunidad Valenciana. Se revisan sus procedimientos de análisis que se concretan con ejemplos de experiencias en esta comunidad, para diferentes escalas y objetivos. También se específica la conveniencia de la integración de ambas para determinar el valor de la conservación del paisaje. La reglamentación actual se encauza en estos términos, ofrece la oportunidad de desarrollo de estos atributos para la efectiva planificación del paisaje y los utiliza para l…
Vitrectomía enzimática por inyección intravítrea de plasmina autóloga como tratamiento inicial de las membranas epirretinianas maculares y el síndrom…
2009
espanolObjetivo: Determinar si la inyeccion intravitrea de plasmina es efectiva en el tratamiento de las membranas epirretinianas maculares (MEM) y el sindrome de traccion vitreomacular (STVM), sin necesidad de asociar vitrectomia quirurgica. Material y metodo Diseno: Estudio piloto prospectivo, de intervencion, serie de casos.
