INTRODUZIONE AL D.LGS. 19 GENNAIO 2017, N. 3, DI ATTUAZIONE DELLA DIR. 2014/104/UE SUL RISARCIMENTO DEI DANNI PER VIOLAZIONE DELLA NORMATIVA ANTITRUST
2018
Con l’emanazione del d.lgs. 19 gennaio 2017, n. 3 e` stata data attuazione alla direttiva 2014/104/UE del Parlamento e del Consiglio del 26 novembre 2014, relativa a determinate norme che regolano le azioni per il risarcimento del danno ai sensi del diritto nazionale per violazioni delle disposizioni del diritto della concorrenza degli Stati membri e dell’Unione europea. Lo scritto, nell'introdurre una serie di commenti alla neo-introdotta normativa, esamina il percorso evolutivo che ha condotto all'emanazione della direttiva, le scelte con essa operate e le modalità di recepimento nell'ordinamento italiano. With the issuance of Legislative Decree January 19, 2017, no. 3 was implemented the…
Características de la micro, pequeña y mediana empresa asociadas a los tipos de tecnologías de comunicación y uso de medios sociales
2015
La dirección en la empresa y su gestión en internet posee un especial interés e importancia, principalmente manifestado en las revistas y periódicos actuales, y en menor medida en la literatura académica. Esta proliferación de nuevas tecnologías ha facilitado la revolución en las comunicaciones en diferentes medios, incluso el uso y la presencia de la empresa en medios sociales en la web. En este sentido, se presenta un resultado de investigación concerniente a explorar el uso de medios de comunicación en línea y de redes sociales y sus relaciones con 1) el tipo de empresa y 2) la apropiación de tecnologías digitales por parte de un conjunto de micro, pequeñas y medianas empresas en Bogotá.…
Photocatalytic ozonation for a sustainable aquaculture: A long-term test in a seawater aquarium
2019
Abstract A long-term test at a laboratory scale with a closed system (a coral reef aquarium) has been carried out to study the potentialities of photocatalytic ozonation and photocatalysis for the removal of noxious organic compounds in recirculating systems (aquaria and recirculating aquaculture systems) working with a minimum make up of new water. Attention has been focused not only on the depuration capabilities but also on possible negative phenomena, some of which could become apparent only at long times. After having tuned the system by setting appropriate operating conditions and procedures, positive results were obtained. In particular, it was observed that the alternation of photoc…
The possibilities of using the aspen poplar seeds (Populus tremula L.) for the purpose of removing monoaromatic hydrocarbons from an aqueous solution
2018
Sorption of oil-related products (including mainly the propellants) is the very basic process that counteracts spreading these types of pollution into environment. Plenty of synthetic substances are used as sorbents for binding organic compounds (including the monoaromatic hydrocarbons) both from the surface and underground waters. The aim of this paper is to present results of the research on the possibilities of using the aspen poplar (Populus tremula L.) seeds as a sorbent of monoaromatic hydrocarbons from an aqueous solution. In order to increase sorption capacity, the seeds biomass was submitted for the process of mercerizing in diversified time and temperature in water and the NaOH so…
Halloysite nanotubes filled with MgO for paper reinforcement and deacidification
2021
Abstract A novel material for the deacidification and protection of paper has been designed by using MgO filled halloysite nanotubes (Hal). The ability of MgO loaded nanotubes to control the acidic conditions was evaluated by pH measurements in aqueous solvent. Afterwards, paper was impregnated into hydroxypropyl cellulose dispersions containing the consolidating material. A simulation of strong acidic conditions allowed us to evaluate the deacidification effect of the composite material on the samples. In particular, the paper reaches a pH of 7.7 after 1 h exposition to HNO3 vapours when MgO-Hal nanoparticles are added to the impregnation mixture at a concentration of 10 wt% and it remains…
Biosorption lead(II) and nikel(II) from an aqueous solution by bacterial biomass
2010
Biosorption lead(II) and nikel(II) from an aqueous solution by bacterial biomass The optimum conditions for biosorption of Pb(II) and Ni(II) from aqueous solution were investigated, by using living and nonliving Pseudomonas fluorescens and Bacillus pumilus isolated from wastewater treatment plant. It was found that the optimum pH for Pb(II) removal by living and nonliving cells was 6.0, while 7.0 for Ni(II) removal. At the optimal conditions, metal ion biosorption was increased as the initial metal concentration increased. The binding capacity by living cells is significantly higher than that of nonliving cells at tested conditions. The maximum biosorption capacities for lead and nickel by …
Las exploraciones arqueológicas de 1930 en los túmulos de "La Mata" (Campanario, Badajoz)
2014
Before systematic excavation made between 1990-2002, the building Protohistoric of "La Mata" (Campanario, Badajoz) was a great mound of land known in the area with the expressive name place "Monton de Tierra Grande", to differentiate it from "Monton de Tierra Chico," a funerary monument and located almost 1 km Southeast of the first one. Both mounds were explored in early 1930 by Virgilio Viniegra Vera and John White Gallardo. These actions, although known, were insufficiently valued in our study of "La Mata" published in 2004 because this documentation wasn’t known to us. Recently we recovered a number of articles and news in the newspapers Correo Extremeno and Sol, that allowed to us to k…
European society of hypertension position paper on ambulatory blood pressure monitoring
2013
Ambulatory blood pressure monitoring (ABPM) is being used increasingly in both clinical practice and hypertension research. Although there are many guidelines that emphasize the indications for ABPM, there is no comprehensive guideline dealing with all aspects of the technique. It was agreed at a consensus meeting on ABPM in Milan in 2011 that the 34 attendees should prepare a comprehensive position paper on the scientific evidence for ABPM.This position paper considers the historical background, the advantages and limitations of ABPM, the threshold levels for practice, and the cost-effectiveness of the technique. It examines the need for selecting an appropriate device, the accuracy of dev…
Enhancer trap infidelity in Drosophila optomotor-blind
2013
Reporter gene activity in enhancer trap lines is often implicitly assumed to mirror quite faithfully the endogenous expression of the "trapped" gene, even though there are numerous examples of enhancer trap infidelity. optomotor-blind (omb) is a 160 kb gene in which 16 independent P-element enhancer trap insertions of three different types have been mapped in a range of more than 60 kb. We have determined the expression pattern of these elements in wing, eye-antennal and leg imaginal discs as well as in the pupal tergites. We noted that one pGawB insertion (omb (P4) ) selectively failed to report parts of the omb pattern even though the missing pattern elements were apparent in all other 15…
A White Paper on keV sterile neutrino Dark Matter
2017
We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting views and insights from all disciplines involved - cosmology, astrophysics, nuclear, and particle physics - in each case viewed from both theoretical and experimental/observational perspectives. After reviewing the role of active neutrinos in particle physics, astrophysics, and cosmology, we focus on sterile neutrinos in the context of the Dark Matter puzzle. Here, we first review the physics motivation for sterile neutrino Dark Matter, based on challenges and tensions in purely cold Dark Matter scenarios. We then round out the discussion by critically summarizing all known constraints on sterile neutrin…
