Resource or waste? A perspective of plastics degradation in soil with a focus on end-of-life options.
2018
‘Capable-of-being-shaped’ synthetic compounds are prevailing today over horn, bone, leather, wood, stone, metal, glass, or ceramic in products that were previously left to natural materials. Plastic is, in fact, economical, simple, adaptable, and waterproof. Also, it is durable and resilient to natural degradation (although microbial species capable of degrading plastics do exist). In becoming a waste, plastic accumulation adversely affects ecosystems. The majority of plastic debris pollutes waters, accumulating in oceans. And, the behaviour and the quantity of plastic, which has become waste, are rather well documented in the water, in fact. This review collects existing information on pla…
Urinaryp-cresol is elevated in young French children with autism spectrum disorder: a replication study
2014
The aromatic compound p-cresol (4-methylphenol) has been found elevated in the urines of Italian autistic children up to 8 years of age. The present study aims at replicating these initial findings in an ethnically distinct sample and at extending them by measuring also the three components of urinary p-cresol, namely p-cresylsulfate, p-cresylglucuronate and free p-cresol. Total urinary p-cresol, p-cresylsulfate and p-cresylglucuronate were significantly elevated in 33 French autism spectrum disorder (ASD) cases compared with 33 sex- and age-matched controls (p < 0.05). This increase was limited to ASD children aged ≤8 years (p < 0.01), and not older (p = 0.17). Urinary levels of p-cresol a…
FIRST MOLECULAR DATA ON DELASTRIA ROSEA, FISCHERULA MACROSPORA AND HYDNOCYSTIS PILIGERA
2011
Several samples of Delastria rosea, Fischerula macrospora and Hydnocystis piligera from the Mediterranean basin are studied, and the first molecular data of these species are reported. A colour plate showing the external morphology of their ascomata is also included.
Detection of a plant enzyme exhibiting chlorogenate-dependant caffeoyltransferase activity in methanolic extracts of arbuscular mycorrhizal tomato ro…
2012
When Glomus intraradices-colonised tomato roots were extracted in methanol at 6 degrees C, chlorogenic acid (5-caffeoylquinic acid), naturally present in the extract, was slowly converted by transesterification into methyl caffeate. The progress of the reaction could be monitored by HPLC. The reaction only occurred when the ground roots were left in contact with the hydro-alcoholic extract and required the presence of 15-35% water in the mixture. When the roots were extracted in ethanol, chlorogenic acid was transformed to ethyl caffeate in the same conditions. The reaction was also detected in Glomus mosseae-colonised tomato root extracts. It was also detectable in non-mycorrhizal root ext…
The complete set of ribosomal proteins from the marine sponge Suberites domuncula
2005
The siliceous marine sponge Suberites domuncula is a member of the most ancient and simplest extant phylum of multicellular animals-Porifera, which have branched off first from the common ancestor of all Metazoa. We have determined primary structures of 79 ribosomal proteins (r-proteins) from S. domuncula: 32 proteins from the small ribosomal subunit and 47 proteins from the large ribosomal subunit. Only L39 and L41 polypeptides (51 and 25 residues long in rat, respectively) are missing. The sponge S. domuncula is, after nematode Caenorhabditis elegans and insect Drosophila melanogaster the third representative of invertebrates with known amino acid sequences of all r-proteins. The comparis…
San cristoforo smart, progetto vincitore del concorso "Il progetto di riqualificazione del territorio comunale prospicente il lago di Caldonazzo".
2013
L’articolo contiene la relazione di progetto e i disegni del progetto vincitore del concorso di riqualificazione del territorio comunale prospicente il lago di Caldonazzo. Rispetto alle funzioni, strutture, infrastrutture e servizi e fruibilità pubblica del territorio la proposta declina in modo coerente le scelte progettuali con il sistema delle risorse presenti sul territorio, valorizzandole mediante l'individuazione di un ambito ludico che coinvolge l'area del Lido e di un ambito naturalistico e culturale che interessa il nucleo storico di San Cristoforo. Viene condotta una analisi approfondita che a seconda delle diverse utenze identificate definisce le nuove attività che consentono di …
L’eccezione di difetto di rappresentanza secondo le Sezioni Unite: a proposito di Cass. Sez. Un. 3 giugno 2015 n. 11377
2015
Nell'articolo in commento viene affrontato il tema della rilevabilità d'ufficio dell'eccezione di difetto di rappresentanza, alla luce della recente sentenza delle Sezioni Unite Cass. sez. un. 3 giugno 2015, n. 11377. La Corte, ribaltando un suo precedente orientamento, ha concluso per il carattere di eccezione in senso lato della difesa in parola, con conseguente rilevabilità d'ufficio. L'autore, aderendo all'orientamento espresso dalle Sezioni Unite, qualifica la difesa de qua, a seconda del suo specifico contenuto, come contestazione del fatto o contestazione del diritto, sul rilievo - condiviso dal giudice di legittimità - che lo pseudo-rappresentato eserciti un diritto potestativo sola…
Halloysite nanotubes as nanoreactors for heterogeneous micellar catalysis
2021
Abstract Hypothesis Electrostatic attractions between the anionic head group of sodium alkylsulphates and the positively charged inner surface of halloysite nanotubes (HNTs) drive to the formation of tubular inorganic micelles, which might be employed as nanoreactors for the confinement of non polar compounds in aqueous media. On this basis, sodium alkylsulphates/halloysite hybrids could be efficient nanocatalysts for organic reactions occurring in water. Experiments Sodium decylsulphate (NaDeS) and sodium dodecylsulphate (NaDS) were selected for the functionalization of the halloysite cavity. The composition, the structure and the surface charge properties of the hybrid nanotubes were dete…
