Spunti di riflessione in materia di reati di gestione e traffico di rifiuti: le necessità di un ripensamento normativo
2023
Il presente contributo intende ravvivare la riflessione penalistica in merito al delitto di attività organizzate per il traffico illecito di rifiuti, attualmente disciplinato dall’art. 452 quaterdecies c.p. Nel far ciò, l’A. parte dall’analisi della struttura della fattispecie, mettendo in dubbio la sua natura di reato abituale, al momento dominante in dottrina e giurisprudenza, in favore di una lettura incentrata sul requisito organizzativo, individuato quale vero baricentro del disvalore del reato in commento. La centralità dell’elemento organizzativo è carattere ricorrente nella normativa antitraffico domestica, e la si riscontra, infatti, anche nel caso oggetto di interesse. Essa reca c…
Effect of temperature on anaerobic treatment of black water in UASB-septic tank systems
2007
The effect of northern European seasonal temperature changes and low temperature on the performance of upflow anaerobic sludge blanket (UASB)-septic tanks treating black water was studied. Three UASB-septic tanks were monitored with different operational parameters and at different temperatures. The results indicated the feasibility of the UASB-septic tank for (pre)treatment of black water at low temperatures with respect to removal of suspended solids and dissolved organic material. Inoculum sludge had little effect on COD(ss) removal, though in the start-up phase some poorly adapted inoculum disintegrated and washed out, thus requiring consideration when designing the process. Removal of …
Particle balance and return loops for microplastics in a tertiary-level wastewater treatment plant.
2021
Highlights: Dewatering by centrifugation was a step that removed a high number of MPs from the sludge. Sludge retained especially the fibrous microplactics. Reject water transported microplastics inside a wastewater treatment plant. Disc filter-based tertiary treatment ensured removal of 99% of microplastics in wastewater. Microplastics (MPs) from households, stormwater, and various industries are transported to wastewater treatment plants (WWTPs), where a high proportion of them are captured before discharging their residuals to watersheds. Although recent studies have indicated that the removed MPs are mainly retained in wastewater sludge, sludge treatment processes have gained less atten…
AMMORTIZZATORI SOCIALI E NUOVE PROSPETTIVE DI WELFARE
In linea con la costruzione di un Modello sociale europeo e con i principi di flexicurity e lotta all’esclusione sociale elaborati nel quadro della Strategia Europa 2020, lo studio ripercorre le tappe dell’auspicato processo di razionalizzazione/universalizzazione del sistema degli ammortizzatori sociali in Italia, al fine di conciliare le istanze di flessibilità del mercato del lavoro con un incremento della sicurezza sociale e dell’occupabilità. In particolare, si analizzano le rilevanti modifiche introdotte dalla legge n. 92 del 2012 (cd. Riforma Fornero), nonché quelle proposte, a distanza di neanche due anni, nell’ennesimo percorso di riforma prefigurato all’interno del cd. Jobs Act , …
Le sculture lignee
2023
Il contributo indaga le sculture lignee ubicate nella chiesa di Santa Maria la Porta di Geraci Siculo. Si tratta di opere eseguite dal XVI al XVII secolo da scultori attestati non solo nel borgo madonita ma anche in altre realtà isolane. Ogni manufatto è collocato nella pertinente temperie culturale The contribution investigates the wooden sculptures located in the church of Santa Maria la Porta in Geraci Siculo. These are works performed from the 16th to the 17th century by sculptors attested not only in the Madonie village but also in other island realities. Each artifact is placed in the pertinent cultural climate
Formare educatori e insegnanti ludici
2020
Che cosa significa “formare insegnanti ed educatori ludici”? Partendo dal significato del termine “Ludico”, il saggio approfondisce in cosa consista la “capacità di giocare” con i bambini e di promuovere il loro gioco libero. Propone quindi una riflessione riguardo ad ambiti, percorsi e metodologie per la formazione sottolineando come questa debba essere caratterizzata: da un apprendimento centrato sull’esperienza, sull’osservazione e sull’auto-osservazione; dalla dimensione di gruppo; dalla interazione tra pari, da attività focalizzate sui linguaggi artistico-espressivi; da un’attenzione alla dimensione psico-corporea ed emotiva. Nella parte conclusiva viene presentato un possibile modello…
The mitogen-activated protein kinase p38 pathway is conserved in metazoans: Cloning and activation of p38 of the SAPK2 subfamily from the sponge Sube…
2000
Our recent data suggest that during auto- and allograft recognition in sponges (Porifera), cytokines are differentially expressed. Since the mitogen-activated protein kinase (MAPK) signal transduction modulates the synthesis and release of cytokines, we intended to identify one key molecule of this pathway. Therefore, a cDNA from the marine sponge Suberites domuncula encoding the MAPK was isolated and analyzed. Its encoded protein is 366 amino acids long (calculated Mr 42 209), has a TGY dual phosphorylation motif in protein kinase subdomain VIII and displays highest overall similarity to the mammalian p38 stress activated protein kinase (SAPK2), one subfamily of MAPKs. The sponge protein w…
Conservation of the positions of metazoan introns from sponges to humans
2002
Abstract Sponges (phylum Porifera) are the phylogenetic oldest Metazoa still extant. They can be considered as reference animals (Urmetazoa) for the understanding of the evolutionary processes resulting in the creation of Metazoa in general and also for the metazoan gene organization in particular. In the marine sponge Suberites domuncula , genes encoding p38 and JNK kinases contain nine and twelve introns, respectively. Eight introns in both genes share the same positions and the identical phases. One p38 intron slipped for six bases and the JNK gene has three more introns. However, the sequences of the introns are not conserved and the introns in JNK gene are generally much longer. Intron…
Signal Recognition Particle 54 kD Protein (SRP54) from the Marine Sponge Geodia cydonium
2002
In the systematic search for phylogenetically conserved proteins in the simplest and most ancient extant metazoan phylum – Porifera, we have identified and analyzed a cDNA encoding the signal recognition particle 54 kD protein (SRP54) from the marine sponge Geodia cydonium (Demospongiae). The signal recognition particle (SRP) is a universally conserved ribonucleoprotein complex of a very ancient origin, comprising SRP RNA and several proteins (six in mammals). The nucleotide sequence of the sponge cDNA predicts a protein of 499 amino acid residues with a calculated Mr of 55175. G. cydonium SRP54 displays unusually high overall similarity (90 %) with human/mammalian SRP54 proteins, higher th…
