The Human Development Index in Historical Perspective: Italy from Political Unification to the Present Day

The aim of this research is to provide a long run estimate of the Human Development Index (HDI) for Italy. To this purpose we have reconstructed Italian historical series relative to life expectancy, literacy rate, school enrolment rates and income. All the series presented are the result of a study which has produced, starting from primary sources, original series disaggregated to the regional level. The possibility of having, for Italy, a basis of comparison with the main developed countries has permitted us to show that, even though there has been significant progress in the values of the single variables, the country has not appreciably improved its position in the world ranking. This seems to be due, in large part, to the trend of the education variables that displays values decidedly distant from those of the main industrialized countries. As far as regional trends are concerned, we can observe a slow process of alignment of the values of the Southern regions to the values of the other Italian regions for levels of education and longevity, while income levels for the 1990s still remain quite distant.

Environmental NMR: Fast-field-cycling Relaxometry

Fast-field-cycling (FFC) NMR relaxometry deals with the variation of the spin–lattice relaxation times (T1) in a complex system, as the strength of the applied magnetic field is changed. Information about molecular dynamics can be achieved. Until now, only model theories for FFC NMR relaxometry have been developed for polymer and material sciences. Just a few applications have been performed in the environmental sciences. These mainly deal with soil porosity, rock permeability, biomass transformations, and natural organic matter dynamics. Further, FFC NMR relaxometry can also be applied to monitor the environmental fate of contaminants, to understand the dynamics of nutrients at the soil–plant interface, and to evaluate reaction mechanisms in heterogeneous catalysis for the development of green reactions. This article summarizes the advances of the technique in environmental investigations and describes the tools used to monitor dynamics of organic and inorganic molecules in environmental compartments

Efficiency of biochar for reducing mobility of inorganic contaminants

Anthropogenic activities have produced numerous sites with extensive contamination close to residential areas. Several physicochemical and biological remediation methods exist for remediation of metal contaminated soils and lands, such as soil washing, soil flushing, phytoremediation, and electrokinetics. Biochar (biologically derived charcoal) is produced by pyrolysis of biomasses under low oxygen conditions, and it can be applied for recycling organic waste in soils. The main objectives of the present study were to determine the possible use of biochar from forest ersidues (Populus nigra) in order to achieve a stabilization of inorganic contaminants by adsorption processes. Adsorption of copper by biochar from dilute solutions showed a closer agreement with the Langmuir isotherm in a concentration range 25-500 mM. The decontamination by biochar is very suitable because the treatment is passive and does not require specialized equipment or extensive labor as compared to other remediation methods. Moreover, biochar is also a possible carbon sink due to its long term storage in environment, thereby favouring mitigation of the anthropic impact on environment

Nature of Interactions at the Interface of Two Water-Saturated Commercial TiO2 Polymorphs

Two commercial TiO2 samples, a 100% anatase and a 100% rutile, were used for the fast field cycling NMR experiments. The results showed a different behavior between the different samples. In particular, water molecules were unbonded to the solid surface for the rutile sample, whereas they appeared to chemically interact with the surface through H-bond formation with the anatase sample. The above findings accord with the generally lower activity of rutile with respect to anatase reported in literature for photocatalytic oxidation reactions in water. The difficulty of water to interact with rutile surface, indeed, could hinder the formation of OH radicals, which are the most important oxidant species

Analisi e definizione di strategie di gestione e controllo di sistemi di accumulo elettrico per applicazioni in reti di distribuzione attive automatizzate Report 1 – Analisi dello stato dell’arte

Il presente Report riferisce sui contenuti e sui risultati della prima fase delle attività svolte nell’ambito della ricerca dal titolo: “Analisi e definizione di strategie di gestione e controllo di sistemi di accumulo elettrico per applicazioni in reti di distribuzione attive automatizzate”, oggetto dell’Accordo di Collaborazione tra ENEA e DIEET sottoscritto nel corso del 2011. Nel corso della prima fase delle attività, a partire da un inquadramento generale dei diversi tipi di accumulo di energia elettrica (elettrochimico, meccanico ed elettrico), è stata condotta un’analisi preliminare su metodologie, sistemi d’interfaccia e tecniche di controllo dei sistemi di accumulo, in una visione il più possibile integrata con le esigenze “di sistema”, ovvero in relazione ai principali aspetti che nei prossimi anni caratterizzeranno il funzionamento delle reti di distribuzione e dei loro diversi componenti/sottosistemi, nell’ottica di transizione verso infrastrutture elettriche efficienti, flessibili, dinamiche ed interattive. Tra tali aspetti, in relazione al contesto generale della ricerca, è stato analizzato in particolare il possibile ruolo dei sistemi di accumulo per: - favorire l’integrazione di generazione di energia da fonti rinnovabili contribuendo a risolvere alcune criticità nei servizi di regolazione della tensione e della frequenza della rete; - contribuire ad elevare i livelli di qualità del servizio elettrico; - partecipare ad una gestione ottimale, in termini tecnico-economici, di tutte le risorse di rete: fonti energetiche, unità di accumulo e carichi (implementando idonei programmi di demand-response). Le attività sono state condotte in sinergia con il personale tecnico di ENEA e sono state svolte prevalentemente all’interno dei locali e dei laboratori del DIEET di Palermo

Analisis Intangible Factors Yang Mempengaruhi Penentuan Harga Produk Karya Seni

This research aims to develop a new quantitative method to determine painting pricing based on 10 intangible factors, i.e. curator, amount of exhibition, painter\u27s year of birth, painting\u27s years of made, auction record,estimation price, exhibition place, painting media, painting size, and previous sales record. The selling price data are obtained from six auction houses. Kano Model and Linear Regression Model are used to examine the relationbetween pricing and each variable. Based on the model development scheme, there are 6 alternative models that can be obtained. Each model then was evaluated by cross-validation procedure using 21 data. Based on the value of R2for each model, the Kano Model with variable previous sales is the best model with R2 of 70

Raw meat based diet influences faecal microbiome and end products of fermentation in healthy dogs

Background: Dietary intervention studies are required to deeper understand the variability of gut microbial ecosystem in healthy dogs under different feeding conditions and to improve diet formulations. The aim of the study was to investigate in dogs the influence of a raw based diet supplemented with vegetable foods on faecal microbiome in comparison with extruded food. Methods: Eight healthy adult Boxer dogs were recruited and randomly divided in two experimental blocks of 4 individuals. Dogs were regularly fed a commercial extruded diet (RD) and starting from the beginning of the trial, one group received the raw based diet (MD) and the other group continued to be fed with the RD diet (CD) for a fortnight. After 14 days, the two groups were inverted, the CD group shifted to the MD and the MD shifted to the CD, for the next 14 days. Faeces were collected at the beginning of the study (T0), after 14 days (T14) before the change of diet and at the end of experimental period (T28) for DNA extraction and analysis of metagenome by sequencing 16SrRNA V3 and V4 regions, short chain fatty acids (SCFA), lactate and faecal score. Results: A decreased proportion of Lactobacillus, Paralactobacillus (P < 0.01) and Prevotella (P < 0.05) genera was observed in the MD group while Shannon biodiversity Index significantly increased (3.31 +/- 0.15) in comparison to the RD group (2.92 +/- 0.31; P < 0.05). The MD diet significantly (P < 0.05) decreased the Faecal Score and increased the lactic acid concentration in the feces in comparison to the RD treatment (P < 0.01). Faecal acetate was negatively correlated with Escherichia/Shigella and Megamonas (P < 0.01), whilst butyrate was positively correlated with Blautia and Peptococcus (P < 0.05). Positive correlations were found between lactate and Megamonas (P < 0.05), Escherichia/Shigella (P < 0.01) and Lactococcus (P < 0.01). Conclusion: These results suggest that the diet composition modifies faecal microbial composition and end products of fermentation. The administration of MD diet promoted a more balanced growth of bacterial communities and a positive change in the readouts of healthy gut functions in comparison to RD diet

Regeneration of cellulose by water addition to phosphoric acid/cellulose mixture

In the last years, phosphoric acid has been increasingly considered as a simple and economic solvent for cellulose pretreatment before its degradation to glucose. Cellulose swells in 71–80% phosphoric acid solutions, whereas at higher H3PO4 concentrations dissolution appears to occur. In addition, it is reported that regenerated cellulose is more easily fermentable to bioethanol. The aim of the present study was to elucidate the mechanism for cellulose regeneration following treatment with phosphoric acid at room temperature. CPMAS 13C NMR spectra revealed a downfield shift of the 13C NMR signals from the regenerated cellulose as compared to the crystalline one. CPMAS 31P NMR spectroscopy showed presence of organic phosphate in the regenerated cellulose. These results suggested that cellulose regeneration consisted in the precipitation of a phosphorylated polymer. Fast field cycling NMR relaxometry confirmed such hypothesis. In fact, the correlation time of water saturated crystalline cellulose was shorter than that measured for the water saturated regenerated cellulose. The phosphate groups bound to the regenerated cellulose surface allow restriction of water mobility, thereby producing longer correlation times. Finally turbidimetric analyses revealed that the mechanism of regeneration consisted in a first reduction of the colloidal cellulose size followed by aggregation, colloidal size increment and flocculation. This study is of paramount importance to understand how phosphoric acid interact with cellulose in order to address its possible uses in biomass transformation for bioenergy purposes
