SALUTE E SICUREZZA NEI LUOGHI DI LAVORO: LE RISPOSTE INTEGRATE DEGLI ORDINAMENTI STATALE E INTERSINDACALE
2020
Il saggio analizza la risposta dell’ordinamento intersindacale all’emergenza epidemiologica da Covid-19 in materia di salute e sicurezza nei luoghi di lavoro attraverso una disamina del Protocollo del 24 aprile 2020, e delle prime applicazioni contrattualcollettive. Tecnicismi a parte, lo studio sottolinea come le misure pattuite dalle parti sociali specificano ed integrano gli obblighi inderogabili e generali di legge in materia di salute e sicurezza. Infine, il saggio si interroga sulla compatibilità tra meccanismi di contact tracing e privacy all'insegna di una prospettiva multi-livello. The essay focuses on the recent measures undertaken by social partners against Covid-19 in the field …
Somministrazione e mancata valutazione dei rischi
2019
L'articolo analizza il recente indirizzo giurisprudenziale relativo alle conseguenze sanzionatorie in caso di ricorso alla somministrazione nelle unità produttive in cui non sia stato predisposto il documento di valutazione dei rischi. The current work deals with the recent jurisprudence about the remedies in case of use of temporary employment in company units lacking of health and safety risk rating document.

Tutela e sicurezza del lavoro tra centro e periferia: la sicurezza sui luoghi di lavoro
2013
Il saggio prende in esame la complessa questione del riparto di competenze tra Stato e Regioni alla luce del Titolo V della Costituzione in materia di salute e sicurezza sui luoghi di lavoro. Il riparto di competenze tra centro e periferia è stato oggetto di una limitata analisi da parte della dottrina e della giurisprudenza, che si sono concentrate in particolare sulla disciplina del mercato del lavoro. L’Autore descrive un sistema multilivello, caratterizzato dalla compresenza di fonti nazionali e regionali, della contrattazione collettiva, nonché di codici di condotta. Sulla scorta di una ricostruzione del quadro normativo e dei percorsi della giurisprudenza, il saggio propone una lettur…
Safety and efficacy of cervical disc arthroplasty in preventing the adjacent segment disease: a meta-analysis of mid- to long-term outcomes in prospe…
2019
Objectives: Cervical disc arthroplasty (CDA) has become an alternative treatment for cervical radiculopathy and myelopathy. This technique preserves appropriate motion at both the index and adjacent disc levels and consequently may prevent adjacent segment degeneration (ASD). The authors performed a meta-analysis to compare the safety and efficacy of CDA to those of the gold standard, anterior cervical discectomy and fusion (ACDF). Both surgical and clinical parameters were employed to verify the hypothesis that CDA can reduce the risk of ASD. Methods: The meta-analysis comprised high-quality randomized controlled trials that compared CDA and ACDF treatments of cervical degenerative disc di…
Speciation of chitosan-phosphate and chitosan-nucleotide systems in an NaCl aqueous solution
2010
AbstractThe speciation of chitosan (310 kDa) with organic (adenosine 5’-monophosphate, AMP, and adenosine 5’-triphosphate, ATP), and inorganic phosphorus containing ligands (phosphate and pyrophosphate) was investigated in NaCl aqueous solutions at I = 0.1mol L−1 and T = 25°C. For all the systems, the investigated results obtained gave evidence for the formation of (chitosan)LHi complex species (L = nucleotides, phosphate and pyrophosphate; i = 1 to 4, but for AMP, i = 1 to 3). The stability data of complex species were used to calculate the sequestering ability of chitosan towards phosphorus compounds considered here, expressed as pL50 i.e., – log(total chitosan concentration) necessary to…
Chemical speciation of organic matter in natural waters. Interaction of nucleotide 5′ mono-, di- and triphosphates with major components of seawater
2004
AbstractThe interactions of nucleotide 5’ mono-, di- and triphosphates in a multicomponent ionic medium simulating the macro-composition of seawater (Na+, K+, Ca2+, Mg2+, Cl-, SO42-, Synthetic Sea Water, SSW) have been investigated at different ionic strengths and at T= 25°C. A chemical speciation model, according to which all the internal interactions between the components of the ionic medium are taken into account, was applied to determine the effective formation constants of species in the nucleotide-seawater system. The results were compared to protonation parameters calculated from single electrolyte systems. A simpler model (SSW considered as a single salt BA, with Bz+ and Az-), repr…
Equilibrium studies in natural fluids: interactions of -PO43−, -P2O74−and -P3O105−with the major constituents of sea water
1998
AbstractThe interaction of PiO(i+2)−(3i+1) (i = 1,2,3) with the major components of seawater has been studied potentiometrically, at 25°C, in an artificial seawater (Na+, K, Ca2+, Mg2+, Cl− and SO42−) at different salinities (5—45%o). Apparent protonation constants have been calculated, from potentiometric data, and estimated, using an appropriate complex formation model. Formation constants of complexes formed by phosphates and the cation of seawater (the inorganic content of seawater being considered as a single 1:1 salt) have been determined. The comparison between experimental and estimated results showed that a suitable complexation model can be used with a fairly good accuracy in pred…
Use of Battery- vs. Petrol-Powered Chainsaws in Forestry: Comparing Performances on Cutting Time
2022
The use of battery tools is very common in many fields of work. In fact, the electric engine and batteries have several advantages over traditional endothermic engines, including low emissions, in terms of pollutants, vibration and noise. In this context, the chainsaw market started producing electric models powered by batteries. These machines can be useful in forestry, but information on their performance is scarce. The aim of this work was to compare the performance, in terms of cutting times, of three Stihl chainsaw models: the MS 220C-B (battery powered), and the MS 201 C-M and MS 261 C-M (both petrol powered). The study was carried out on five different wood species, also taking into …
A Forensic Diagnostic Algorithm for Drug-Related Deaths: A Case Series
2022
The best evidence provided in the literature worldwide suggests the importance of harmonizing the investigation in drug-related fatalities. In this study, the application of a multidisciplinary approach in eight cases of drug-related deaths is presented. Although death scene findings could be highly suggestive of drug intoxication, external examination and toxicological screening test alone are insufficient. There are several variables, and it is not always easy to give the proper interpretation of the drug detection. A complete autopsy is necessary to correctly complete organ and tissues sampling for further histological and toxicological studies and obtain body fluids. The use of peripher…
