The proposed strategy, for outlier removal and wavelength reduction, allowed the achievement of useful results. Principal component regression fit/prediction capability produced excellent results. Conversely, partial least squares regression showed fair/poor results and the remaining tested models performed badly on real data. © 2017 Society of Chemical Industry.

Making cities smarter and more competitive is one of the major challenges of climate change and energy\ud security. Smart city initiatives have arisen Europe-wide to help cities to start planning their future in a\ud new way to become more sustainable and resilient. New business models need to be investigated to\ud foster local business development, innovative local administrations and industries, valorize the cultural\ud heritage and the research outcomes and promote community’s participation. This transition is even\ud more complex and necessary for sparsely populated regions with poor infrastructures in the buildings,\ud manufacturing and transport domains and with a multi-layer local governance (e.g. Italian Towns,\ud Provinces and Region). In this case, a widespread concept of smart city can be applied proposing\ud systematic strategies for urban innovation with a regional-wide perspective. This paper focuses on a\ud coordinated project aimed to promote smartness among local areas in a small region in Southern Italy\ud (Basilicata). The ‘Smart Basilicata’ project constitutes a unique example in which, by working together,\ud multi-layer public authorities, private enterprises, research organizations and universities drafted the\ud basis for a regional strategy for smart-related issues

Phenolic compounds are useful markers to control olive oil technological processes, including the virgin olive oil (VOO)/water separation after olive oil extraction. In this investigation, VOO extracted from olives of cv. Coratina using a mild oil/water separator called the hydrocyclone sedimentation system (Hydroil) was compared with VOO obtained using a conventional vertical centrifuge separator (Cenoil), which is mostly used in the modern olive oil industry. Secoiridoid aglycones were selected, among phenolic compounds, as markers and analyzed using reversed-phase liquid chromatography coupled to linear quadrupole ion-trap mass spectrometry with electrospray ionization in the negative mode. VOO samples obtained using the Hydroil system were found to contain significantly higher levels of secoiridoid aglycones, compared to the Cenoyl-type samples. In particular, the total content of the aglycones of decarboxymethyl oleuropein, decarboxymethyl ligstroside, ligstroside, and oleuropein, expressed in terms of oleuropein, was estimated as 35.40 AE 0.80 mg kg −1 , compared to 8.06 AE 0.41 mg kg −1 in the Cenoil samples (n = 3). Since no significant difference in residual water (P < 0.05) was found between the two types of VOO samples, the higher amount of secoiridoids obtained for Hydroil-type ones was explained by the lower extent of oxidation occurring during the mild oil/water separation achieved using the Hydroil system.
