Natural Fiber-Reinforced Composites

2012

Over the last decade, composites of polymers reinforced with natural fibres have received increasing attention, both from the academic world and from several industries. There is a wide range of natural fibres which can be applied as reinforcements or fillers thanks to their properties and availability; i.e. flax, hemp, jute, kenaf and sisal. Natural fibres are mainly attractive for the following reasons: specific properties, price, health advantages and recyclability. Particularly, industry is getting more and more interested in environment-friendly products and therefore the research on natural fibre based on composite materials is gaining importance. Some of the benefits linked to the us…

The Body of the Soul. Lucretian Echoes in the Renaissance Theories on the Psychic Substance and its Organic Repartition

2015

In the 16th and 17th centuries, when Aristotelianism still was the leading current of natural philosophy and atomistic theories began to arise, Lucretius’ De Rerum Natura stood out as an attractive and dangerous model. The present paper reassesses several relevant aspects of Lucretius’ materialistic psychology by focusing on the problem of the soul’s repartition through the limbs discussed in Book 3. A very successful Lucretian image serves as fil rouge throughout this survey: the description of a snake chopped up, with its pieces moving on the ground (Lucretius DRN 1969, 3.657–669). The paper’s first section sets the poet’s theory against the background of ancient psychology, pointing out …

A lack of meaning?

2020

This article explores the ‘lack of meaning’ in contemporary society as a consequence of Western dualist thought paradigms and ontologies, via Gilles Deleuze’s concept of ‘reactive nihilism’ following the colloquial murder of God. The article then explores processual and new materialist approaches in the understanding of the lived and carnal self, arguing for immanent and senseful materiality as an ethical platform for religious, environmental, and societal solidarity for tomorrow. For the theoretical justification of the processual approach in understanding the enfleshed self, the article employs John Dupré’s processual approach in the philosophy of biology, as well as Astrida Neimani’s cri…

Ontology Views for Ontology Change Management

2014

International audience; In the literature, ontology change management systems (OCMS) are direct implementation of the concept of “change management” stated by reference (Klein, 2004). Ontology change management combines ontol- ogy evolution and versioning features to manage ontol- ogy changes and their impacts. Since 2007, many works have combined ontology evolution and versioning into ontology change management systems (OCMS). The evolution subject has been massively studied in these works. They especially addressed the consistence issue for the application of changes on the ontology. These proposals constituted a consequent background for ontology change management but they did not take i…

Evaluation and application of Opuntia ficus-indica insulation panel

2015

Today the attention to the building sustainability issue is increasingly important, because of the major responsibility of the buildings field in the environmental degradation: both in terms of energy consumption from non-renewable sources and the raw materials impoverishment. In addition, the level of comfort required by users are growing and the thermal insulation of buildings becomes the key element in the reduction of energy consumption and C02 emissions, both in the case of new construction and existing ones. The thermal insulation of buildings is the key element in the reduction of energy consumption and C02 emissions due to the cooling of building interiors, both in the case of new c…

Photo-stabilization of biopolymers-based nanocomposites with UV-modified layered silicates

2020

Abstract Eco-friendly in-situ stabilised biopolymer nanocomposites based on polyamide 11 (PA11) and polylactic acid (PLA) were prepared by melt mixing in the presence of a modified organo-montmorillonite clay containing a chemically-bound hindered amine UV-stabilising function, [(UV)OM-MMt]. Characterisation of the newly synthesised organo-modifier containing the reactive hindered amine (HAS) UV-stabilising function [(UV)OM] has confirmed a successful synthesis. The (UV)OM was then introduced into NaMMt through ion exchange reaction to prepare the UV stabiliser-bound organo-modified-MMt, [(UV)OM-MMt]. The in-situ stabilised PA11- and PLA- nanocomposites (PA11-(UV)OM-MMt and PLA-(UV)OM-MMt) …

Thermomechanical Characterization of Polylactic Acid and Composites

2018

This paper presents the experimental tests for the thermomechanical characterization of biopolymer polylactic acid, and its composites with beech flour or with nanoreiforcement of modified montmorillonite, in order to evaluate any applicability in the automotive sector. Tests of torque and traction are executed for the mechanical characterization and the results comparison; dynamical tests are executed for the thermomechanical characterization, determining the elastic modulus and loss factor versus the actual temperature.
