Recycled Tyre Rubber Modified Bitumens for road asphalt mixtures: A literature review
2013
AbstractNowadays, only a small percentage of waste tyres are being land-filled. The Recycled Tyre Rubber is being used in new tyres, in tyre-derived fuel, in civil engineering applications and products, in moulded rubber products, in agricultural uses, recreational and sports applications and in rubber modified asphalt applications. The benefits of using rubber modified asphalts are being more widely experienced and recognized, and the incorporation of tyres into asphalt is likely to increase. The technology with much different evidence of success demonstrated by roads built in the last 40years is the rubberised asphalt mixture obtained through the so-called “wet process” which involves the…
The microbiology of Lascaux Cave.
2010
Lascaux Cave (Montignac, France) contains paintings from the Upper Paleolithic period. Shortly after its discovery in 1940, the cave was seriously disturbed by major destructive interventions. In 1963, the cave was closed due to algal growth on the walls. In 2001, the ceiling, walls and sediments were colonized by the fungus Fusarium solani. Later, black stains, probably of fungal origin, appeared on the walls. Biocide treatments, including quaternary ammonium derivatives, were extensively applied for a few years, and have been in use again since January 2008. The microbial communities in Lascaux Cave were shown to be composed of human-pathogenic bacteria and entomopathogenic fungi, the for…
Il sogno dell'ascesa al trono di Teodosio nell'Epitome de Caesaribus
2007
L’Epitome de Caesaribus fornisce una versione originale rispetto all’ascesa al trono di Teodosio, che sarebbe stata preannunciata da un sogno, attraverso cui è spiegato il nome del futuro imperatore in quanto a Deo natus. Nell’articolo è indagato il contesto in cui può essersi formata la versione di un imperatore voluto da Dio.
A possible use of selected essential oils and Citrosept to inhibit the growth of Fusarium solani Mart. (Sacc.)
2016
Laboratory experiments have been carried out to determine the effects of lemon, cedar, pine and thyme oils as well as Citrocept on the growth of Fusarium solani Mart. (Sacc.) mycelium isolated from stored potato tubers. The biotic property of essential oils and Citrocept in inhibiting the linear growth of F. solani was assessed with the use of poisoned culture media, whereas the fungistatic property was determined by calculating, with the use of Abbott formula, the percentage indicating how many fungal colonies were inhibited from growth. A complete inhibition of the pathogen’s growth was observed in the presence of thyme oil at a concentration of 0.2% to 2% as well as in the presence of le…
Inferencia Estadística (2010/11)
2010
Los contenidos de la materia , tras repasar y consolidar algunas cuestiones del cálculo de probabilidades , especialmente las distribuciones multivariantes y las derivadas de las distribución normal, se centran en los recursos teóricos fundamentales para resolver los dos problemas esenciales de la inferencia estadística: la estimación de parámetros y el contaste de hipótesis
Nueva evidencia sobre el uso de la cooperación entre empresas en España en el período de 1994-1999: Características y evolución
2003
La cooperación interempresas se ha convertido en una práctica habitual en la dirección de las empresas, constituyendo una respuesta estratégica a un entorno en el que se intensifica de forma creciente la competencia y la necesidad de acceder a un abanico cada vez mayor de tecnologías y capacidades. A partir de una muestra de 611 alianzas identificadas en la prensa económica entre 1994 y 1999, este trabajo pretende describir las características actuales en el uso de la cooperación por parte de las empresas españolas, así como analizar la evolución del fenómeno, comparando los resultados del estudio con las tendencias observadas durante etapas anteriores y ofreciendo posibles explicaciones a …
Evaluation of Inciso: A system for automatic elaboration of a Citation Index in Social Science Spanish Journal
2007
We have developed a system that can elaborate a citation index in an automated way. It has been tested with Spanish journals. We need evaluate our system, mainly in effectiveness of the retrieval of citations. Criteria for evaluation of the system is presented and discussed, and the results of the application to our system are showed and analyzed.
Universal natural shapes: From unifying shape description to simple methods for shape analysis and boundary value problems
2012
Gielis curves and surfaces can describe a wide range of natural shapes and they have been used in various studies in biology and physics as descriptive tool. This has stimulated the generalization of widely used computational methods. Here we show that proper normalization of the Levenberg-Marquardt algorithm allows for efficient and robust reconstruction of Gielis curves, including self-intersecting and asymmetric curves, without increasing the overall complexity of the algorithm. Then, we show how complex curves of k-type can be constructed and how solutions to the Dirichlet problem for the Laplace equation on these complex domains can be derived using a semi-Fourier method. In all three …
“Buoni e cattivi esempi”. Cicerone, Cesare e l’ombra di Silla
2021
The exemplum, one of the tools of persuasion indicated by ancient rhetoric, is used by Cicero in Caesarian Orations with a careful strategy: the exemplary modeling of Caesar allows to define the boundaries of the correct management of res publica. Therefore, in the Pro Marcello Caesar is already presented as a “visible” exemplum, while in the following Pro Ligario the paradigm of Sulla (i.e. that of a dictator guided by crudelitas) becomes effective in admonishing Caesar from a possible degeneration of power.
Countering Adversarial Inference Evasion Attacks Towards ML-Based Smart Lock in Cyber-Physical System Context
2021
Machine Learning (ML) has been taking significant evolutionary steps and provided sophisticated means in developing novel and smart, up-to-date applications. However, the development has also brought new types of hazards into the daylight that can have even destructive consequences required to be addressed. Evasion attacks are among the most utilized attacks that can be generated in adversarial settings during the system operation. In assumption, ML environment is benign, but in reality, perpetrators may exploit vulnerabilities to conduct these gradient-free or gradient-based malicious adversarial inference attacks towards cyber-physical systems (CPS), such as smart buildings. Evasion attac…
