Le Elezioni Politiche 2013

Le elezioni politiche del 24 e 25 febbraio 2013 hanno sancito un forte cambiamento della struttura del sistema partitico italiano. In un contesto di altissima volatilità elettorale e di accelerato declino della partecipazione al voto, il sistema è divenuto sostanzialmente tripolare, dopo vent’anni di strutturazione e tenuta del bipolarismo. A questo esito hanno concorso da un lato l’erosione dei principali schieramenti politici che a partire dal novembre 2011 avevano sostenuto l’esperienza del governo Monti (nonché la deludente prova elettorale dello stesso Presidente del Consiglio uscente), e dall’altro lo straordinario successo del Movimento 5 stelle. Quest’ultimo, al primo test elettorale di livello nazionale, ha raccolto un risultato sorprendente, giungendo ad oltre un quarto dei voti validi. Siamo di fronte ad una parentesi momentanea dovuta all’effetto combinato di crisi economica e crisi politica, oppure le contraddizioni interne alla Seconda Repubblica l’hanno condotta effettivamente al suo crepuscolo? Come uscirà il sistema partitico italiano da questa nuova fase di destabilizzazione? Questo quarto Dossier CISE, che raccoglie contributi apparsi sul sito web del Cise prima e dopo le elezioni, fornisce una prima analisi del voto, presentando elaborazioni su dati aggregati, stime dei flussi elettorali, alcune prime analisi su dati di sondaggio, nonché una panoramica dei nuovi eletti e un’appendice ricca di tabelle e mappe riassuntive del risultato elettorale. Come i precedenti Dossier, si tratta di uno strumento prodotto rapidamente all’indomani del voto, con l’intento di suggerire primi spunti di interpretazione da approfondire in seguito, cercando di contribuire alla lettura di un risultato elettorale cruciale, in una delicata fase di cambiamento del sistema partitico italiano

Transient shift of diacylglycerol and inositol lipids induced by interferon in Daudi cells Evidence for a different pattern between nuclei and intact cells

AbstractThe effect of human recombinant DNA interferon-α type A on inositol lipid and diacylglycerol metabolism was investigated in Daudi lymphoma whole cells and isolated nuclei. In isolated nuclei after 90 min of interferon treatment an enhanced rate of PIP2 phosphorylation and an increase of DAG mass were observed. In whole cells, after 1 min of interferon treatment, there was a rapid and transient shift of DAG mass apparently not related to inositol lipid modifications, thus indicating the presence in nuclear and cytoplasmic compartments of inositol lipid fractions with different metabolic features in response to interferon-α

Self-Powered Edible Defrosting Sensor

Improper freezing of food causes food waste and negatively impacts the environment. In this work, we propose a device that can detect defrosting events by coupling a temperature-activated galvanic cell with an ionochromic cell, which is activated by the release of ions during current flow. Both the components of the sensor are fabricated through simple and low-energy-consuming procedures from edible materials. The galvanic cell operates with an aqueous electrolyte solution, producing current only at temperatures above the freezing point of the solution. The ionochromic cell exploits the current generated during the defrosting to release tin ions, which form complexes with natural dyes, causing the color change. Therefore, this sensor provides information about defrosting events. The temperature at which the sensor reacts can be tuned between 0 and -50 °C. The device can thus be flexibly used in the supply chain: as a sensor, it can measure the length of exposure to above-the-threshold temperatures, while as a detector, it can provide a signal that there was exposure to above-the-threshold temperatures. Such a device can ensure that frozen food is handled correctly and is safe for consumption. As a sensor, it could be used by the workers in the supply chain, while as a detector, it could be useful for end consumers, ensuring that the food was properly frozen during the whole supply chain

The impact of fluid loss and carbohydrate consumption during exercise, on young cyclists’ fatigue perception in relation to training load level

High-level young athletes need to face a wide spectrum of stressors on their journey to élite categories. The aims of the present study are (i) to evaluate session rate of perceived exertion (sRPE) at different training impulse (TRIMP) categories and the correlations between these two variables and, (ii) evaluate the correlations between sRPE, fluid loss, and carbohydrate consumption during exercise. Data on Edward’s TRIMP, sRPE, body mass loss pre-and post-exercise (∆), and carbohydrate consumption (CHO/h) during exercise have been acquired from eight male junior cyclists during a competitive season. One-way ANOVA and correlation analysis with linear regression have been performed on acquired data. sRPE resulted in a significant difference in the three TRIMP categories (p < 0.001). sRPE resulted in being very largely positively associated with TRIMP values (p < 0.001; R = 0.71). ∆ as well as CHO/h was largely negatively related with sRPE in all TRIMP categories (p < 0.001). The results confirmed the role of fluid balance and carbohydrate consumption on the perception of fatigue and fatigue accumulation dynamics independently from the training load. Young athletes’ training load monitoring and nutritional-hydration support represent important aspects in athlete’s exercise-induced fatigue management

Multi-technique characterization of pictorial organic binders on XV century polychrome sculptures by combining microand non-invasive sampling approaches

A stony sculptural composition of the Nativity Scene is preserved in Altamura’s Cathedral (Apulia, Italy). This commonly called Apulian “presepe”, attributed to an unknown stonemason, is composed of polychrome carbonate white stone sculptures. While earlier stratigraphic tests have unveiled a complex superimposition of painting layers—meaning that several editions of the sculptures succeeded from the 16th to 20th century—a chemical investigation intended to identify the organic binding media used in painting layers was undertaken. Drawing on current literature, two strategies were exploited: a non-invasive in situ digestion analysis and an approach based on microremoval of painting film followed by the Bligh and Dyer extraction protocol. Both peptide and lipid mixtures were analyzed by matrix-assisted laser desorption/ionization-mass spectrometry (MALDIMS) and reversed-phase liquid chromatography coupled to mass spectrometry by electrospray ionization (RPLC-ESI-MS). Attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FTIR) examinations were also performed on micro-samples of painting films before lipids and proteins extraction. While human keratins were found to be common contaminants of the artwork’s surfaces, traces of animal collagen, siccative oils, and egg white proteins were evidenced in different sampling zones of the sculptures, thus suggesting the use of non-homogeneous painting techniques in the colored layers

Effectiveness of a 5-week virtual reality versus traditional training on balance and flexibility in healthy adult females

Purpose This study aimed to investigate the effectiveness of a 5-week virtual reality training protocol on static and dynamic balance and flexibility compared to a traditional training protocol in healthy adult females. Methods Twenty-one healthy female adults (age, 49.81 +/- 2.99 years) were randomly assigned into three groups: Virtual Reality (VR; n = 7) that performed a 5-week exergame training protocol; Traditional Training (TR; n = 7) that performed a specific training protocol on balance, and lower limbs and abdominal strength; and waitlist control group (CG; n = 7) that continued their daily activities without any type of structured physical activity. Static balance was assessed by the ellipse area and statokinesigram parameters (Romberg test, in the open-eye (OE) and closed-eye (CE)), dynamic balance by the star excursion balance test on the right and left leg, and flexibility by the sit and reach test. Results After the intervention, VR and TR groups showed a significant improvement in static and dynamic balance and flexibility (all p < 0.001) compared to the CG. Compared to TR, the VR training protocol showed greater effect sizes and was more effective in percentage terms on all measured variables, particularly for Sit and Reach (82% vs. 35%), except the OE Area (42% vs. 49%). Conclusions Findings suggest that both a 5-week VR training protocol and a 5-week TR protocol may significantly improve static and dynamic balance and flexibility in healthy female adults. The VR training protocol showed a greater effect size compared to the TR training protocol, although it was not statistically significant. Future randomized controlled studies with a larger sample size and longer training protocols are needed to confirm this finding
