Blackcurrants constitute an important source of potential health promoting phytochemicals (e.g. phenolic compounds, ascorbic acid) due to their antioxidant properties. Only small portions of berries are consumed fresh, most of their intake coming from processed foods, such as juices. Seven techniques were used to measure antioxidant capacity and antioxidant compounds of 10 juices. This yielded a large disparity of results. No single test, even the most popular ORAC assay, is able to compare the antioxidant capacity of similar food matrix such as blackcurrant juices. By combining tests from a large battery of « antioxidant » assays, it is possible to improve the discrimination of a food matrix by establishing a Global Antioxidant Score (GAS) which correlates well with graphical representations like Chernoff faces or stars. The latter approaches may help food industry managers and authorities to compare their « antioxidant » products with those existing on the market. [less ▲]

Nel 2011 l’UNESCO ha adottato la Raccomandazione sul Paesaggio Storico Urbano che mira al riconoscimento e all'identificazione della stratificazione e dell'interconnessione dei valori - naturali e culturali, materiali e immateriali, internazionali e locali – riscontrabili in qualsiasi città storica, concepita come un “patrimonio vivente” delle comunità. In tale visione il patrimonio culturale urbano è un elemento riconosciuto non solo dagli esperti, ma dalle intere società che ne valutano gli elementi identitari mirando a conservarli per le generazioni future. La Raccomandazione, in particolare, sostiene che per l'interpretazione e la conservazione del patrimonio culturale si può beneficiare di metodi di valutazione tradizionali e di metodi innovativi basati su dati geo-localizzati e sui dati digitali dei social media, come tweets geo-localizzati, impronte digitali e foto su Flickr. Il presente contributo illustra una metodologia basata sull’analisi delle immagini su Flickr. Dai risultati ottenuti si è evinto che proprio l’indagine dei social media può contribuire ad una comprensione significativa dei valori culturali del contesto urbano, fornendo così la possibilità di una migliore integrazione dei valori socio-culturali riconosciuti dalla collettività nei processi di conservazione e di pianificazione urbana.

In situ measurements of ocean properties are generally sparsely distributed and thus undersample the ocean variability. Deriving ocean climatologies is a challenging task especially for biological and chemical parameters where the number of data is, by an order of magnitude, smaller than for physical parameters. However, physical and biogeochemical parameters are related through the ocean dynamics. In particular fronts visible in physical parameters are often related to gradients in biogeochemical parameters. Ocean climatologies are generally derived for different variables independently. For biogeochemical parameters, only the very large-scale variability can be derived for poorly sampled areas. Here we present a method to derive multivariate analysis taking the relationship between physical and biogeochemical variables into account. The benefit of this procedure is showed by using model data for salinity, nitrate and phosphate of the Mediterranean Sea. The model fields are sampled at the locations of true observations (extracted from the World Ocean Database 2013) and the analysed fields are compared to the original model fields. The multivariate analysis result in a reduction of the RMS error and to a better representation of the gradients [less ▲]

Our current ability to produce mesoporous materials with ordered morphology has raised fascinating questions about the impact of geometrical disorder on adsorption and desorption states [1]. Many recent works have investigated the role of mild elements of disorder, such as local constriction or corrugation superimposed to otherwise geometrically ideal cylindrical pores [2,3]. These works have notably shown that elements of disorder may act as nucleation sites and destabilize vapor-like metastable states. The relevance of these perturbation-like results to fundamentally disordered materials, such as gels, is unclear. In particular, do vapor-like metastable states exist at all in this type of very disordered material? In the present communication, we address this question using probabilistic models to investigate the role of disorder. We generalize the classical Gaussian field models of porous materials [4] and use them to analyze adsorption and desorption in the Derjaguin-Broekhof-de Boer approximation. Our approach differs from earlier contributions in that both the adsorbent and the adsorbate are described in terms of probabilities [5]. This enables us to analyze the adsorbate configuration in very disordered solids using a low-dimensional yet realistic configuration space. We notably show that vapor-like metastable states are unlikely in gel-like disordered materials. [1] D.Wallacher, N. Künzner, D. Kovalev, N. Knorr, K.
