Graphene nanosystems as supports in siRNA Delivery
2018
The nature of graphene-based nanosystems, as well as the possibility to synthesize them at low cost, have made them in the last few years, an interesting proposition in tumour therapy as a drug delivery system. Here, a reduced form of graphene oxide (RGO) has been synthesized and conjugated with a specific antibody for active targeting against tumour cells (RGOY). Furthermore, its bi-dimensional nature permits also p- p stacking interactions with planar molecules like siRNA (RGOY-siRNA). All these nano-complexes were characterized by DLS and DSC analysis, TEM and Raman spectroscopy and their biocompatibility was demonstrated by viability assay on cell line ECV 304. The system is able to be …
Formulation of Different Chitosan Hydrogels for Cartilage Tissue Repair
2014
Different formulations of Chitosan/sulphate and Chitosan/PEGDE were produced by physical and chemical reticulation to obtain hydrogels with better physiochemical properties. The hydrogels were analyzed – in terms of their non-toxicity, proliferative, differentiative, inflammatory and immunology responses. Commercial grade Chitosan (Sigma) was solubilized and purified by progressive filtrations. Then, the polymer was freeze-dried in a water soluble cationic form. A physical hydrogel was prepared by mixing a 3 % w/w water solution of the a.m. polymer with different stoichiometric ratios of (SO4=) 1/0.5;1/0.75;1/1 respectively. The hydrogels were cross-linked in multiwells. The chemical hydrog…
The Ability of Water Hyacinth (Eichhornia crasipes Mart.) and Water Lettuce (Pistia stratiotes Linn.) for Reducing Pollutants in Batik Wastewater
2021
Batik produced by craftsmen is categorized as a small and medium industry. The problem of Batik production is less attention to the environment because the craftsmen lived in the middle of a residential area that has inexperience. One of less attention to the environment is no treatment of wastewater that reaches up to 95 % (61.9 L each cloth). Thus it polluted the river. This research aimed to treat the wastewater of Batik production by using phytoremediation. In this study, phytoremediation was carried out in three tanks in series using Eichhornia crassipes and Pistia stratiotes which are abundant in Indonesia. The treated wastewater was evaluated for its ammonia and chromium (Cr). The re…
Dynamic of Components Leachate from Experimental Fertilizers in Leaching Test
2018
Organic matter contained in the waste of food industry or occurring in the households, in the absence of contamination with other kind of waste, may be used to create a “fertiliser”, which could be even reused in the organic production of arable crops. Particular attention is drawn to the fertilisers which may be applied in the case of amateur cultivation of pot plants and in the allotment gardens. The paper presents the results of research regarding the dynamics of the release of nutrients from tablets created with the help of encapsulation of the mixture manufactured from solvent extraction waste of coffee (SCG), modified by the ash obtained from low temperature burning of biomass. In thi…
Le misure di riorganizzazione del personale alle dipendenze della p.a. Tra obiettivi di efficienza ed esigenze di razionalizzazione della spesa pubbl…
2012
Riassunto- Il saggio analizza le politiche di riorganizzazione del personale alle dipendenze delle p.a., alla luce delle più recenti modifiche legislative. Secondo le più recenti analisi statistiche, la Pubblica Amministrazione italiana registra, a livello strutturale, numerose inefficienze correlate all’irrazionale distribuzione delle risorse umane. Per ovviare a dette disfunzioni, il legislatore è intervenuto a più riprese sul quadro normativo in materia di mobilità, modificando sia la disciplina degli strumenti di programmazione e gestione delle risorse umane (passaggi diretti di personale, trasferimenti, comandi, distacchi e assegnazioni temporanee), sia i meccanismi regolativi per il …
Flexicurity as a measuring leakage protection of workers: between "social pollution" and "total security"
2012
Was not the labour problem the same everywhere? The paper attempts to answer this question by proposing a re-interpretation of flexicurity through the comparison with the economic concepts of externalities and distortion of competition. After a methodological and epistemological premise, based on a multidisciplinary literature, the paper - critically addresses the origins of flexicurity and argues that it lacks an archetypical definition, especially in the formulation of the EU Commission. Hence, the paper considers flexicurity as any balance between flexibility and security and, therefore, proposes ordering any set of contracts, providing the same balance and with the same regulatory fr…
Sul nuovo rito dei licenziamenti e una proposta di modifica
2012
Lo studio propone una prima analisi delle norme che regolano il c.d. nuovo rito dei licenziamenti, introdotto dalla riforma Fornero, come complemento alla modificazione disciplina della reintegrazione e dei licenziamenti collettivi, allo scopo di snellire e accelerare i processi in questa materia e di aumentare la certezza in ordine alla risoluzione dei rapporti. Chiude lo studio un'appendice in cui l'autore propone un modello alternativo di rito dei licenziamenti.The study provides an initial analysis of the rules of the new trial of dismissals. It introduced by the Fornero reform, as a complement to the modification both dismissal reinstatement and collective redundancies. The purpos…

Lo studio affronta il tema della somministrazione di lavoro in ambito marittimo.
La tutela del credito nel diritto del lavoro (pignorabilità e compensabilità)
2010
Questo studio, dopo la ricostruzione della disciplina della pignorabilità e compensabilità dei crediti del lavoratore, analizza criticamente l'istituto della compensazione atecnica e ne propone una rilettura coerente con la struttura della fattispecie e la ragione d'essere dei limiti alla compensazione. This study, after the reconstruction of the discipline of the distrainteness and of the countervailability of the credit of the employee, critically analyses the institution of latu sensu countervailability and eventually proposes a new reading consistent with the structure of the case and the raison d'etre for legal limits for the employee's credits' countervailability.
La crisi del diritto del lavoro
2012
Riassunto - L’Autore ripercorre in chiave critica l’evoluzione delle politiche legislative in materia di lavoro, alla luce dell’attuale fase di crisi economico finanziaria. Nell’esaminare i principali interventi normativi attuati da inizio secolo, l’Autore mette in evidenza le scelte di metodo e gli elementi di continuità che accomunano i vari provvedimenti, individuandoli nell’affannosa ricerca del punto di equilibrio tra flessibilità e garantismo. La riflessione si chiude con alcuni interrogativi sulle ultime linee di riforma del mercato del lavoro e con l’auspicio che, anche al cospetto delle imprescindibili ragioni dell’economia, il diritto del lavoro possa continuare a svolgere il pro…
