The Effect of Halogen Bonding on the Packing of Bromine Substituted Pyridine and Benzyl Functionalized Resorcinarene Tetrapodands in the Solid State
2012
The synthesis and characterization of new bromine-substituted pyridine and benzyl functionalized tetramethoxy resorcinarene tetrapodands are described and their solid-state structural properties and interactions were studied by single crystal X-ray crystallography. Three different crystal structures were obtained for the pyridine derivative and one for the benzyl derivative, which revealed that the interactions of the bromine substituent have an explicit effect on the crystal packing of the resorcinarene molecules. One of the structures obtained had very interesting halogen–halogen interactions with the same geometry as is generally found for compounds used in nonlinear optical studies. pee…
GREEN LOGISTICS – A DIFFERENT AND SUSTAINABLE BUSINESS GROWTH MODEL
2014
Built on the concepts of green logistics and green supply chain management (GrSCM), this paper presents the relationship between logistical activities and its related environmental effects and costs. By greening their supply chain, companies can better use their assets, optimize resources- do more with less, improve and create sustainable technology, ensure continuity and strategic, long-term alliances. Business ethics and social responsibility are important components of organisational effectiveness. Most companies recognize that socially responsible activities improve their image among consumers, stakeholders, the financial community and other relevant publics. They have found that enviro…
Danno da prodotto difettoso e responsabilità delle piattaforme di E-Commerce: uno sguardo oltreoceano
2022
L’articolo prende in esame due recenti decisioni della Court of Appeal della California circa la responsabilità delle piattaforme di e-commerce per prodotti difettosi alienati da venditori circa la responsabilità delle piattaforme di e-commerce per prodotti difettosi alienati da venditori terzi. Dopo aver ricostruito il case law californiano in materia di danno da prodotto ed il ruolo della tradizionale filiera distributiva nel migliorare la sicurezza dei prodotti, l’Autore passa all’esame delle pronunce della Court of Appeal rese nei casi Bolger v. Amazon.com del 2020 e Loomis v. Amazon.com del 2021. Secondo la Corte di secondo grado, le piattaforme di e-commerce sono destinatarie del regi…
Recenti sviluppi della giurisprudenza di legittimità in tema di responsabilità e tutela del cessionario d'azienda
2021
L’ordinanza della Corte di Cassazione afferma in modo non condivisibile che la responsabilità del cessionario che abbia trascurato di richiedere la certificazione prevista dall’art. 14,comma3, del D.Lgs. n. 472/1997 possa essere estesa anche ad imposte e sanzioni commesse prima del secondo anno anteriore a quello in cui è intervenuta la cessione, anche se constatate dopo il trasferimento dell’azienda. I giudici di legittimità correttamente fanno dipendere l’aggravamento della responsabilità del cessionario dalla consapevolezza della frode posta in essere dal cedente. Tuttavia escludono la necessità di notificare a quest’ultimo l’avviso di accertamento che costituisce il presupposto dell’isc…
Optimization of Spray-Drying Process of
2019
Jerusalem artichoke is an important natural matrix for inulin production. In this experiment, response surface methodology (RSM) was employed to optimize the spray-drying parameters in order to determine the maximal inulin yield. For this study, three independent variables (heating temperature (Tª, 110–120 °C), creep speed (V, 18–22 rpm) and pressure (P, 0.02–0.04 MPa)) were used in the experimental design. Using the Box–Behnken design, the optimal parameters obtained were: drying temperature 114.6 °C, creep speed 20.02 rpm, and pressure: 0.03 MPa. The inulin yield, water content and particle size of inulin obtained by spray-drying and freeze-drying were compared. In this regard, the spray-…
Parental Competence in Infant and Primary Education: design and validation of an instrument
2021
Actualmente, la familia se encuentra ante retos que requieren de su eficiencia y eficacia en la crianza, protección y orientación de los hijos, es decir, la parentalidad y la capacidad de los padres de ejercerla de forma competente. Desde este punto de vista, destaca la necesidad de un modelo educativo centrado en el desarrollo de las competencias parentales que proporcione conocimientos, habilidades y actitudes que optimicen el rol parental respecto al desarrollo pleno y sistémico del ser humano. Ante la necesidad de conocer si los padres asumen de forma óptima su papel en la educación de sus hijos, se plantea como objetivo principal de este artículo el diseño de un instrumento para el aná…
Pronóstico del retratamiento de conductos no quirúrgico
2017
PRONÓSTICO DEL RETRATAMIENTO DE CONDUCTOS NO QUIRÚRGICO El tratamiento de conductos es un procedimiento conservador que tiene un alto porcentaje de éxito a largo plazo. Sin embargo, algunos dientes endodonciados presentan patología periapical y los signos y síntomas del paciente no desaparecen después del tratamiento. El retratamiento de conductos no quirúrgico trata las patologías asociadas al fracaso endodóntico, y en algunos casos está indicado con fines restauradores (23). Consiste en la eliminación del material intraconducto, la detección de deficiencias, y la reparación de los defectos patológicos o iatrogénicos, seguido de la instrumentación y limpieza y la obturación final de los co…
Charged supramolecular assemblies of surfactant molecules in gas phase
2016
The aim of this review is to critically analyze recent literature on charged supramolecular assemblies formed by surfactant molecules in gas phase. Apart our specific interest on this research area, the stimuli to undertake the task arise from the widespread theoretical and applicative benefits emerging from a comprehensive view of this topic. In fact, the study of the formation, stability, and physicochemical peculiarities of non-covalent assemblies of surfactant molecules in gas phase allows to unveil interesting aspects such as the role of attractive, repulsive, and steric intermolecular interactions as driving force of supramolecular organization in absence of interactions with surround…
Reverse Screening on Indicaxanthin from Opuntia ficus-indica as natural chemoactive and chemopreventive agent
2018
Indicaxanthin is a bioactive and bioavailable betalain pigment extracted from Opuntia ficus indica fruits. Indicaxanthin has pharmacokinetics proprieties, rarely found in other phytochemicals, and it has been demonstrated that it provides a broad-spectrum of pharmaceutical activity, exerting antiproliferative, anti-inflammatory and neuromodulator effects. The discovery of the Indicaxanthin physiological targets plays an important role in understanding the biochemical mechanism. In this study, combined reverse pharmacophore mapping, reverse docking, and text-based database search identified Inositol Trisphosphate 3-Kinase (ITP3K-A), Glutamate carboxypeptidase II (GCPII), Leukotriene-A4 hydro…
