Use of plant growth-promoting rhizobacteria (PGPR) and organic fertilization for soilless cultivation of basil
2021
Abstract Today there is a greater environmental and ecological awareness and it is growing the number of farmers who want to adopt sustainable and efficient cultivation systems even if not officially certified as organic. Sustainable and modern cultivation systems must involve organic fertilization and cannot ignore the role of rhizosphere microorganisms. Starting from this premise, this paper aimed to evaluate the use of plant growth-promoting rhizobacteria (PGPR) and organic liquid fertilizers on soilless cultivation of basil. Genovese basil plants were cultivated in pots filled with a substrate inoculated or not with a commercial biostimulant (TNC BactorrS13) containing growth-promoting …
Engagement del consumidor a través del contenido generado por las empresas en instagram
2021
Purpose: The purpose of this paper is to analyse the impact of consumers’ perceptions of the enjoyment and originality of firm-generated content (FGC) posted on Instagram on affective customer engagement (CE). In addition, an examination is undertaken of affective CE as a driver of customer behaviour. Design/methodology/approach: The paper takes a quantitative approach using a sample of 334 women followers of an eco-friendly restaurant Instagram account. After validation of the measurement scales, the hypotheses were tested through structural equation modelling. Drawing on the stimuli-organism-response framework the authors posit that consumers’ perceptions of the enjoyment and originality …
EFFECTS OF PRE-PLANT SOIL TREATMENTS ON STRAWBERRY IN SICILY
2014
The 2005 ban by Italy of methyl bromide (MB) has resulted in significant crop management difficulties in pre-plant soil dis-infestation. We report two pre-plant soil treatment techniques and their effects on the performance of new cultivars and selections tolerant to the main root pathogens. The plants grown in soil treated with chloropicrin + 1,3 dichloropropene were the most productive. While neither treatment affected average berry weight, soluble solids content or titratable acidity, the treatment × cultivar interaction was significant and fruits from plants grown in treated soil were firmer than control s. Selection PA 260 and cultivar Florida Fortuna were the earliest, three selection…
Random short sisal fiber biocomposites: Optimal manufacturing process and reliable theoretical models
2018
Although several works have been published in literature on agave fibers and their biocomposites, accurate information about the choice of both the fibers and the manufacturing processes that allow the user to optimize the biocomposites properties in terms of strength and stiffness are not yet available; also, no theoretical models that can be used for an accurate evaluation of the mechanical properties of these biocomposites, are reported.To this aim, the present work intends to give a contribution by considering green epoxy biocomposites reinforced by both short and discontinuous sisal agave fibers arranged in proper MAT-type fabrics. In particular, an optimized manufacturing process that…
Implementation of eco-sustainable biocomposite materials reinforced by optimized agave fibers
2018
Abstract Although several works have recently been published in literature about biocomposites, i.e. about composites with polymeric matrix reinforced by natural fibers, only a few articles have been devoted to the implementation of high performance biocomposites for structural and semi-structural applications. The present study aims to give a contribution by considering biocomposites obtained by using an eco-friendly partially bio-based epoxy (green epoxy) and sisal (agave sisalana fibers) obtained by a proper optimization process. Through a systematic experimental analysis, three different types of biocomposites obtained with a suitable manufacturing process, such as random short fiber bi…
Untreated Opuntia ficus indica for the Efficient Adsorption of Ni(II), Pb(II), Cu(II) and Cd(II) Ions from Water
2023
The raw cladode of Opuntia ficus indica (OFI) was evaluated as a sustainable biosorbent for the removal of heavy metals (Ni, Pb, Cu, and Cd) from aqueous solutions. The functional groups of OFI were identified by employing DRIFT-FTIR and CP-MAS-NMR techniques before and after contact with the ions in an aqueous media, showing a rearrangement of the biomass structure due to the complexation between the metal and the functional groups. The adsorption process was studied in both single- and multi-component systems under batch conditions at different pHs (4.0, 5.0, and 6.0), different metal concentrations, and different biomass amounts. The results show that the raw OFI had a removal capacity a…
Riflessioni a margine dell’ordinanza cautelare del 26 novembre 2021 del Tribunale di Gorizia: greenwashing tra concorrenza sleale e diritto del consu…
2022
La pubblicizzazione sul mercato di prodotti ecofriendly non di rado si è rivelata frutto di pratiche scorrette di c.d. greenwashing, ciò consistendo in ipotesi di concorrenza sleale capaci di alterare i sistemi competitivi del libero mercato e ledere il diritto dei consumatori all’acquisto consapevole. Simili atti sono oggi sanzionati ricorrendo ad inibitorie e a comunicazioni pubbliche in cui l’impresa infedele informa i propri consumatori circa l’ingannevolezza dei comportamenti posti in essere. In tale ambito, che in primo luogo interessa il settore agroalimentare, si inserisce l’ordinanza cautelare del 26 novembre 2021 del Tribunale di Gorizia. Il ricorso a disciplinari di produzione ba…
Green synthesis of silver nanoparticles mediated by Pulicaria glutinosa extract
2013
Mujeeb Khan,1 Merajuddin Khan,1 Syed Farooq Adil,1 Muhammad Nawaz Tahir,2 Wolfgang Tremel,2 Hamad Z Alkhathlan,1 Abdulrahman Al-Warthan,1 Mohammed Rafiq H Siddiqui1 1Department of Chemistry, College of Science, King Saud University, Riyadh, Kingdom of Saudi Arabia; 2Institute of Inorganic and Analytical Chemistry, Johannes Gutenberg-University of Mainz, Mainz, Germany Abstract: The green synthesis of metallic nanoparticles (NPs) has attracted tremendous attention in recent years because these protocols are low cost and more environmentally friendly than standard methods of synthesis. In this article, we report a simple and eco-friendly method for the synthesis of silver NPs using an aqueous…
Encouraging ecological behaviour through induced hypocrisy and inconsistency.
2016
International audience; Remembering one’s past transgressions of a social norm is known as an effective paradigm for enhancing pro-social and ecological behaviours. Our study aimed to show that reminding one’s norm transgressions can arise cognitive dissonance and can lead to behavioural change as induced hypocrisy does. In particular, we tested whether inconsistency between the self-concept and the remembered past transgressions is or is not likely to encourage behavioural change. To reach this goal, we conducted an experiment comparing induced hypocrisy, injunctive inconsistency and descriptive inconsistency with five comparison conditions. The results showed that, as observed with the in…
Investigation on a low environmental impact solvent mixture applied to a wooden painted slab
2016
Cleaning is one of the most complex and delicate step in a restoration project, often due to the manufacturing techniques of the artifacts and their advanced state of decay. Eco-friendly solvents can permit to execute the cleaning operations with a reduced health impact for the restorers and for the environment. In this work, the performance of the 1,3- dioxolane/methylal (DIOX-MET) solvent mixture is evaluated over a wooden painted slab that had been covered with a thin layer of a protective varnish, probably during a previous conservation work performed in the Sixties. Removal of this varnish has been considered on behalf of its yellowing degradation process, which caused chromatic change…
