A comparative economic analysis of torrefied pellet production based on state-of-the-art pellets
2017
Abstract Torrefied pellets have fuel properties superior to those of conventional wood pellets and potentially allow greater rates of co-firing and thus larger reductions in net CO 2 emissions. Despite the growing amount of scientific output on torrefaction, the economic feasibility of torrefied pellet production is still a topic of considerable uncertainty. This is an obstacle for decision makers looking to implement sustainable energy policies. This paper compares the economics of torrefied pellets to conventional wood pellets. Working backwards from demonstrated pellet properties, this work attempts to answer the following question: Based on state-of-the-art torrefied pellets, what would…
Lignans from Torreya jackii identified by stopped-flow high-performance liquid chromatography–nuclear magnetic resonance spectroscopy
1999
Abstract Coupled reversed-phase HPLC–NMR spectroscopy has been applied to the rapid detection and identification of plant metabolites of Torreya jackii , a species of Taxaceae. Analysis consisted of gradient HPLC elution and directly coupled 1 H NMR (500 MHz) spectroscopic detection in a stopped-flow mode. Seven lignans were detected and their structures were elucidated, based on their HPLC– 1 H NMR spectra and MS data. The structures were confirmed by isolation of the single components followed by conventional NMR measurements.
The façade-tower of Santa Maria delle Stelle Church in Comiso. Historical events, vulnerability and conservation strategy
2020
Dopo avere richiamato l’estesa vicenda storica della costruzione della chiesa Madre di Santa Maria delle Stelle a Comiso, iniziata nel 1736 e terminata due secoli dopo, il contributo è focalizzato sul tema del completamento della sua facciata con l’uso della struttura intelaia di calcestruzzo di cemento armato, progettata dall’ingegnere Santoro Secolo. In tempi più recenti, alcuni dissesti improvvisi hanno posto in evidenza il tema del rischio e la necessità di interventi per risanare la struttura architettonica. L’importanza del monitoraggio e della manutenzione, intesi come fondamentali strategie di conservazione, concludono l’articolo.
Online Multi-Person Tracking by Tracker Hierarchy
2012
Tracking-by-detection is a widely used paradigm for multi-person tracking but is affected by variations in crowd density, obstacles in the scene, varying illumination, human pose variation, scale changes, etc. We propose an improved tracking-by-detection framework for multi-person tracking where the appearance model is formulated as a template ensemble updated online given detections provided by a pedestrian detector. We employ a hierarchy of trackers to select the most effective tracking strategy and an algorithm to adapt the conditions for trackers' initialization and termination. Our formulation is online and does not require calibration information. In experiments with four pedestrian t…
MCD: Overcoming the Data Download Bottleneck in Data Centers
2013
The data download problem in data centers describes the increasingly common task of coordinated loading of identical data to a large number of nodes. Data download is seen as a significant problem in exascale HPC applications. Uncoor-dinated reading from a central file server creates contention at the file server and its network interconnect. We propose and evaluation a reliable multicast based approach to solve the data download problem. The MCD system builds a logical multi-rooted tree based on the physical network topology and uses the logical view for a two-phase approach. In the first phase, the data is multicasted to all nodes. In the second phase, the logical tree is used for an effi…
El cuerpo y la ausencia: la obra literaria de Enrique J. Vila Torres
2014
Resumen: En este ensayo se analiza la obra literaria del abogado y escritor espanol Enrique Vila Torres, artifice, en 2011, de una clamorosa denuncia colectiva concerniente una de las mas horribles violaciones de los derechos humanos acaecida en un pais occidental en el siglo XX: la salvaje compraventa a escala nacional de miles de bebes, robados con el engano a sus madres biologicas. Sus cuentos, todos basados en hechos reales, constituyen un genero hibrido en que se representa la evidencia del cuerpo y las circunstancias del engendramiento, el trauma de la separacion forzada y la consecuente ausencia, el fluir de una vida desgarrada basada en la mentira y la jadeante busqueda del propio c…
Guillermo de Torre y el catálogo de la editorial Losada
2016
Resumen Este trabajo intenta establecer las causas que expliquen por qué Editorial Losada, cuyo catálogo había incluido muchos de los títulos más relevantes de la literatura latinoamericana y argentina de los años cuarenta, comenzó a experimentar un declive a causa de su evolución conservadora en el terreno formal en 1955. Entre estos factores se destaca la renuncia de Guillermo de Torre como director editorial en 1955 y se explica el papel que el crítico y editor tuvo en la evolución del proyecto editorial. Palabras clave: Losada, literatura argentina, Guillermo de Torre. Abstract This paper tries to set the causes which explain why the Publishing Company Losada, whose catalogue had incl…
