RIASSUNTO. L'Europa è la regione con il più forte consumo di alcol al mondo, con la più elevata percentuale di malattie totali e morti premature alcol-correlate. In Italia, questo fenomeno coinvolge circa il 13% della popolazione oltre i 18 anni e oltre il 25% dei pazienti ospedalizzati. Sfortunatamente, solo il 5% di questi pazienti vengono riconosciuti come persone affette da disturbo da uso di alcol (DUA). Una scarsa conoscenza della malattia, la mancanza di accesso alle cure e le poche risorse messe a disposizione nella gestione del problema sono tra le principali cause di ritardo nella diagnosi, alla fine con conseguenze cliniche molto più importanti e costose da gestire. Alla luce di ciò, abbiamo deciso di dedicare questo numero speciale della Rivista di psichiatria a una serie di articoli riguardanti le linee guida italiane per il trattamento della dipendenza da alcol. Realizzate in collaborazione con numerosi esperti e importanti società scientifiche italiane come il Centro di Riferimento Alcologico della Regione Lazio (CRARL), la Società Italiana Tossicodipendenze (SITD), la Società italiana per il Trattamento dell'Alcolismo e le sue Complicanze (SITAC), la Società Italiana Psichiatria delle Dipendenze (SIPDip), la Società Italiana Patologie da Dipendenza (SIPaD) e l'Istituto di Biologia Cellulare e Neurobiologia (IBCN-CNR), queste linee guida forniscono agli operatori una serie di raccomandazioni basate su prove di efficacia volte ad aumentare la conoscenza e un uso appropriato dei farmaci per le persone affette da DUA. Con la possibilità di un continuo aggiornamento, l'obiettivo principale di queste linee guida sarà quello di garantire l'omogeneità dei trattamenti e un incremento qualitativo nell'assistenza dei pazienti affetti da DUA, così da ridurre le conseguenze psicosociali e sulla salute pubblica di questa importante malattia psichiatrica.

Mineralogical, geochemical and isotopic characteristics of alkaline mafic igneous rocks from Punta delle Pietre Nere (Gargano, Southern Italy)

NASA Astrophysics Data System (ADS)

Mazzeo, F. C.; Arienzo, I.; Aulinas, M.; Casalini, M.; Di Renzo, V.; D'Antonio, M.

2018-05-01

The Punta delle Pietre Nere (Gargano, Southern Italy) igneous body is constituted by gabbroic and syenitic rocks with lamprophyric affinity of different age (58 and 62 Ma, respectively). The chemical composition of the minerals clearly indicates that there is no genetic relationship between the two lithotypes, in agreement with their significant age difference. The chemical (trace elements) and Sr-Nd-Pb-isotopic composition of these rocks highlights an "anorogenic" geochemical affinity derived from mixed DMM-HIMU-EM mantle reservoirs, similarly to other Paleogene-Oligocene magmatic provinces in the Circum-Mediterranean Area. In past literature, these features were interpreted as evidences for enriched asthenospheric mantle plume upwelling from deep regions beneath the Western Europe. Here we suggest that the HIMU-like composition of Punta delle Pietre Nere rocks is related to a lithospheric mantle source bearing amphibole-rich veins, resulting from crystallization of melts within the amphibole stability field in presence of H2O, as shown by several experimental works. Our results suggests partial melting at 70-90 km depth, which corresponds to the spinel-garnet transition (2.5-3.5 GPa) close to the amphibole stability limit ( 90-110 km and 2.5-3.5 GPa).

2015-01-01

To investigate the effectiveness of the Well at Dell comprehensive health management program in delivering health care and productivity cost savings relative to program investment (i.e., return on investment). A quasi-experimental design was used to quantify the financial impact of the program and nonexperimental pre-post design to evaluate change in health risks. Ongoing worksite health management program implemented across multiple U.S. locations. Subjects were 24,651 employees with continuous medical enrollment in 2010-2011 who were eligible for 2011 health management programming. Incentive-driven, outcomes-based multicomponent corporate health management program including health risk appraisal (HRA)/wellness, lifestyle management, and disease management coaching programs. Medical, pharmacy, and short-term disability pre/post expenditure trends adjusted for demographics, health status, and baseline costs. Self-reported health risks from repeat HRA completers. Analysis: Propensity score-weighted and multivariate regression-adjusted comparison of baseline to post trends in health care expenditures and productivity costs for program participants and nonparticipants (i.e., difference in difference) relative to programmatic investment. The Well at Dell program achieved an overall return on investment of 2.48 in 2011. Most of the savings were realized from the HRA/wellness component of the program. Cost savings were supported with high participation and significant health risk improvement. An incentive-driven, well-managed comprehensive corporate health management program can continue to achieve significant health improvement while promoting health care and productivity cost savings in an employee population.

Cantico Delle Creature: A microtonal original composition for soprano and string quartet to a text by St. Francis of Assisi, including analytical commentary

NASA Astrophysics Data System (ADS)

Sabol, Jason A.

Cantico delle Creature is an original piece of music for soprano and string quartet composed in 72 tone per octave equal temperament, dividing each semitone into six equal parts called twelfth-tones. This system of tuning makes it possible to combine just intonation and spectral principles based on the harmonic series with real imitation, modulation, and polyphony. Supplemental text discusses several aspects of microtonal structure and pedagogy, including the representation of the first 64 partials of the harmonic series in 72 tone equal temperament, performance of natural string harmonics, the relationship between interval size and vibration ratio, pitch to frequency conversion, and analysis of several passages in the musical score.

We study the performance of inter-process communication on four high-speed multiprocessor systems using a set of communication benchmarks. The goal is to identify certain limiting factors and bottlenecks with the interconnect of these systems as well as to compare these interconnects. We measured network bandwidth using different number of communicating processors and communication patterns, such as point-to-point communication, collective communication, and dense communication patterns. The four platforms are: a 512-processor SGI Altix 3700 BX2 shared-memory machine with 3.2 GB/s links; a 64-processor (single-streaming) Cray XI shared-memory machine with 32 1.6 GB/s links; a 128-processor Cray Opteron cluster using a Myrinet network; and a 1280-node Dell PowerEdge cluster with an InfiniBand network. Our, results show the impact of the network bandwidth and topology on the overall performance of each interconnect.

"Parco Archeologico Storico Naturale delle Chiese Rupestri del Materano": geomorphological fragility and slope instability in a rupestrian-heritage rich area (Basilicata, south Italy).

Francioso, R.; Sdao, F.; Tropeano, M.

2003-04-01

The Italian Ministry of Education, University and Research financed a research project about the study and the control of hydrogeological hazard of some sites belonging to the "Parco Archeologico Storico Naturale delle Chiese Rupestri del Materano"; the Park and the old city of Matera ("Sassi di Matera") was inserted in the UNESCO World Heritage list since 1993. The studied sites ("Belvedere Chiese Rupestri" and "Iazzo dell'Ofra" localities) are located along the top of the walls of the deep canyon (locally called "Gravina di Matera" and deeper than 100 m) which characterizes the area. Several valuable medieval rupestrian hand-hewn rock churches and sanctuaries are present along the canyon walls. The canyon cut weak rocks (Plio-Pleistocene calcarenites, in which churches and sanctuaries are excavated) and the underlying well-stratified limestones (Cretaceous calcilutites). Both rocks are abundantly and strongly fractured and disjointed by several different joint sets, and, on the left wall of the "Gravina di Matera" canyon, they are characterized by a mainly dipping-slope attitude. Consequently, rock blocks of different sizes formed (up to some tens of m^3 in volume), and are characterized by low stability condition. The considerable acclivity of the walls and the defects and intense fracturing state of rocks, especially along the edge, cause rapid falls, topples and rockslides of the blocks. This geomorphological fragility, confirmed by wide-spread signs of potential instability and by several rock blocks fell in the stream, causes the diffuse and significant structural-failures processes that involve most of the very fine rupestrian heritages. Our study, after the geological and geomorphological description of the sites and the editing of thematic maps, concentrates on the determination the present-day slope instability conditions. Moreover, the study demonstrated the notable genetic relationship between jointing, slope instability and failure type of carbonate

Hollow form as a function of boulder size in the Valley and Ridge province, southwestern Virginia

NASA Astrophysics Data System (ADS)

Mills, Hugh H.

1989-07-01

Dells (hollows) that corrugate the antidip slopes of strike-ridge mountains in the Valley and Ridge province of southwestern Virginia vary greatly in cross-section form. This form is a function not of the underlying bedrock, but of the size and durability of boulders supplied to slopes by sandstones capping the strike ridge. Where the largest boulders are smaller than about 0.5 m in intermediate diameter, deep V-shaped dells occur. Where the largest boulders are larger than about 1.0 m, dells are shallow and U-shaped. Boulder size apparently determines the type of erosional processes that predominate in the development of the dells, and thereby dell form. Where boulder size is sufficiently small, running water is the dominant process and incises V-shaped dells. Where boulders are so large that even the largest floods cannot move them, the dell floor is armored and fluvial incision is greatly reduced. The evolution of such dells is dominated by debris flows that have recurrence intervals measured in millenia and by lateral fluvial erosion along the margins of the bouldery dell fill, both of which tend to produce shallow, U-shaped dells. Some evidence for the armoring effect of large boulders was obtained by applying a technique developed for reconstructing flash-flood peaks from boulder deposits. This procedure indicates that boulders in the V-shaped dells could be transported by high but plausible water flows, whereas movement of boulders in the U-shaped dells would require implausibly high flows.

Geophysical investigations at the Paleolitic site Grotta delle Veneri near Parabita (Lecce, Italy)

Carrozzo, M. T.; Leucci, G.; Negri, S.; Nuzzo, L.

2003-04-01

The human presence in Apulia (southern Italy) is documented since 80.000 years before present. In 1966 near Parabita (Lecce, Italy) in a cave subsequently named "Grotta delle Veneri" human remains belonging to Homo Sapiens Neanderthalensis (Neanderthal) and Homo Sapiens-Sapiens (Cro-Magnon) were recovered together with two small statues of pregnant women ("Veneri") referable to 12.000--10.000 b.C. The local Archaeological Superintendence was interested in assessing the possibility to reconstruct by means of geophysical methods the planimetric position of the cave and further development of its burrows beyond those accessible to speleologists and reported in the underground topographic survey. Both electromagnetic (EM) and electric methods were tested using Ground Penetrating Radar (GPR) with 200 and 500 MHz antennas, GEM300 multi-frequency EM induction device and 2D Electrical Resistivity Tomography (ERT). Despite the rough surface and the presence of numerous obstacles (trees, stone walls and stone piles) limiting the accessible survey area and often preventing a good ground-coupling, the GPR survey successfully located the top of the karstic cave and identified zones of high density of diffraction hyperbolas, interpreted as highly fractured and karstified limestone, in a layer ranging from about 2 m to 6 m below ground. Zones characterised by high density of diffractions due to presence of voids were found also outside the known development of the cave. By means of the GEM 300, both in-phase and quadrature components of the induced EM signal were simultaneously collected at 8 frequencies, from 2025 to 19975 Hz, respectively related to the magnetic susceptibility and apparent conductivity of the soil down to a depth decreasing as the frequency increase. A presumable low contrast in the sought parameter between the highly fractured rock and karstic voids or refilled cavities as well as the presence of metallic debris on the ground allowed a difficult identification

La continua espansione delle attività di perforazione ai fini dell'estrazione petrolifera in prossimità di aree abitate ha fatto sì che negli ultimi anni l'attenzione si focalizzasse sull'impatto di questo processo fortemente industrializzato sulla salute pubblica. Le comunità che vivono nei dintorni di impianti di questo tipo devono, infatti, fronteggiare diversi problemi, quali l'inquinamento atmosferico e acustico, la contaminazione del suolo e delle acque sotterranee, il traffico dei camion da e verso il sito, incidenti e malfunzionamenti all'interno dell'impianto. In questo contesto, la valutazione del rischio per la salute è ostacolata dal fatto che l'esposizione alle sostanze chimiche presenti non può essere valutata in via definitiva, poiché non sempre si è a conoscenza di tutti i composti immessi nell'ambiente né delle loro concentrazioni, per non parlare del problema delle coesposizioni ad altri inquinanti. Nonostante l'oramai conclamato e vasto interesse generato da questo argomento, ad oggi esistono pochi studi basati su popolazioni riguardanti gli effetti sulla salute delle comunità che vivono in prossimità dei siti di perforazione ed estrazione; ciò genera la necessità di condurre campagne di monitoraggio mirate e studi epidemiologici che verifichino l'eventuale esistenza e natura di pattern di malattie associati a tali attività. La presente rassegna bibliografica individua, quindi, i principali inquinanti atmosferici presenti in prossimità di un impianto di primo trattamento del greggio e cerca di fornire un quadro generale delle loro potenziali sorgenti e caratteristiche.

Aspetti deontologici e giuridici della Responsabilità professionale del chirurgo in Italia. Evoluzione storica a partire dal '900.

Picardi, Nicola

2018-01-01

È pleonastico ricordare che ogni individuo raziocinante delle essere responsabile delle sue azioni: deve agire con la coscienza degli scopi che si propone evitando possibili conseguenze negative dei suoi atti. In ambito medico questo tipo di responsabilità è codificata con le norme della "deontologia". Per secoli l'arte terapeutica è stata praticata da individui dotati di una particolare vocazione ed una particolare cultura acquisita da Maestri dell'arte ancor prima che dalla propria esperienza, con nozioni di erboristeria e di elementari conoscenze anatomiche e di fisiologia, circondati da un'aura sacerdotale e da un rispetto derivante dal timore e dall'ammirazione per il coraggio e auspicabilmente dai successi, e facendo riferimento nell'occidente mediterraneo alle regole operative fissate nel Giuramento di Ippocrate, di significato tra il sacro ed il deontologico. Lo sviluppo delle tecniche anestesiologiche a partire dalla seconda metà dell'800 ha determinato l'ampliamento delle iniziative chirurgiche di tipo elettivo, a fianco con gli storici interventi in emergenza per la cura di lesioni traumatiche, ancor prima delle acquisizioni riguardanti le infezioni. Con l'espansione del campo di azione della chirurgia, le possibili complicanze ed i possibili insuccessi hanno fatto da contrappeso ai sentimenti di rispetto e di fiducia nei confronti dei chirurghi, giungendo a far assimilare in tali casi la loro opera quale causa all'origine di danni, provocati rientrando quindi nella categoria dei reati sottoposti alla Legge penale. Così, al termine deontologico di "responsabilità" valido per ogni iniziativa ed ogni professione, per i medici è venuto ad associarsi la qualifica di "professionale", con un significato di presunta colpevolezza. Da una parte le regole deontologiche si sono ampliate, ed hanno coinvolto direttamente il paziente nella fase decisionale delle terapie chirurgiche, formalizzate programmaticamente in moderni codici deontologici ed

We present a study, carried out on photographic images, of the ecliptic strip of the Atlas Farnese, a statue found before 1550 in Rome. This statue was supposedly carved according to the celestial catalogue compiled around 129 b. C. by Hypparchus but subsequently lost. The obliquity of the ecliptic is deduced as 24.1° ± 0.5° along with the width of the strip of 7.5°, in good agreement with Ptolemy's Almagest table of planetary inclinations (Book XIII.5).

New insights about the presence of celestite into fossil bones from Molí del Baró 1 site (Isona i Conca Dellá, Lleida, Spain)

NASA Astrophysics Data System (ADS)

We have addressed an X-ray fluorescence (XRF) and X-ray diffraction (XRD) on a collection of thirteen fossil bone belonging to the Molí del Baró 1 paleontological site located near Sant Romà d'Abella (Isona i Conca Dellà Municipality, Lleida Province, Spain, dated to about 66.5 Ma, to investigate the fossilization occurred in this site in terms of physico-chemical properties. As a general behaviour, the XRD patterns showed the bioapatite mineral at a varying level of percentage, and accordingly, the correspondent XRF spectra turned out to be mainly dominated by the presence of Ca, obviously accompanied by phosphorus. Simultaneously, other elements such as Sr, Fe, Ba and Zn were found at non-negligible concentration levels and helped to assign the phase components in the XRD spectra. In three specimens, it was observed by XRD the rather unusual case where the original bioapatite bone mineral was completely substituted for by other mineralogical phases. In addition to this, celestite was also found as an important phase in ten specimens out of the thirteen examined. The occurrence of celestite in the bone structure appears a rather unusual observation within the literature of bones diagenesis. Its provenance is generally ascribed to marine vertebrate organisms, but the presence in the fossil bones of this site, where no evidence of marine environment exists, can be reconciled with occurrence of refluxing processes involving diagenetically altered fluids which were discharged into beds containing strontium sulphate-rich waters.

Comparative analysis of fruit aroma patterns in the domesticated wild strawberries “Profumata di Tortona” (F. moschata) and “Regina delle Valli” (F. vesca)

Strawberry is one of the most valued fruit worldwide. Modern cultivated varieties (Fragaria × ananassa) exhibit large fruits, with intense color and prolonged shell life. Yet, these valuable traits were attained at the cost of the intensity and the variety of the aroma of the berry, two characteristics highly appreciated by consumers. Wild species display smaller fruits and reduced yield compared with cultivated varieties but they accumulate broader and augmented blends of volatile compounds. Because of the large diversity and strength of aromas occurring in natural and domesticated populations, plant breeders regard wild strawberries as important donors of novel scented molecules. Here we report a comprehensive metabolic map of the aroma of the wild strawberry Profumata di Tortona (PdT), an ancient clone of F. moschata, considered as one of the most fragrant strawberry types of all. Comparison with the more renowned woodland strawberry Regina delle Valli (RdV), an aromatic cultivar of F. vesca, revealed a significant enrichment in the total level of esters, alcohols and furanones and a reduction in the content of ketones in in the aroma of PdT berries. Among esters, particularly relevant was the enhanced accumulation of methyl anthranilate, responsible for the intensive sweetish impression of wild strawberries. Interestingly, increased ester accumulation in PdT fruits correlated with enhanced expression of the Strawberry Alcohol Acyltransferase (SAAT) gene, a key regulator of flavor biogenesis in ripening berries. We also detected a remarkable 900-fold increase in the level of mesifurane, the furanone conferring the typical caramel notes to most wild species. PMID:25717332

To establish the concordant validity of the "Checklist per la Valutazione dell'Esordio Psicotico" (CVEP) in an Italian help-seeking population. The CVEP is the Italian adaptation of the "early detection Primary Care Checklist," a 20-item tool specifically designed to assist primary care practitioners in identifying young people in the early stages of psychosis. The checklist was completed by the referring practitioners of 168 young people referred to the "Reggio Emilia At Risk Mental States" Project, an early detection infrastructure developed under the aegis of the Regional Project on Early Detection of Psychosis in the Reggio Emilia Department of Mental Health. The concordant validity of the CVEP was established by comparing screen results with the outcome of the "Comprehensive Assessment of At Risk Mental States" (CAARMS), a gold standard assessment for identifying young people who may be at risk of developing psychosis. The simple checklist as originally conceived had excellent sensitivity (98%), but lower specificity (58%). Using only a CVEP total score of 20 or above as cut-off, the tool showed a slightly lower sensitivity (93%) with a substantial improvement in specificity (87%). Simple cross-tabulations of the individual CVEP item scores against CAARMS outcome to identify the more discriminant item in terms of sensitivity and specificity were carried out. In comparison to other, much longer, screening tools, the CVEP performed well to identify young people in the early stages of psychosis. Therefore, the CVEP is well suited to optimize appropriate referrals to specialist services, building on the skills and knowledge already available in primary care settings. © 2017 John Wiley & Sons Australia, Ltd.

Evidence for the involvement of a nonlexical route in the repetition of familiar words: A comparison of single and dual route models of auditory repetition.

PubMed

Hanley, J Richard; Dell, Gary S; Kay, Janice; Baron, Rachel

2004-03-01

In this paper, we attempt to simulate the picture naming and auditory repetition performance of two patients reported by Hanley, Kay, and Edwards (2002), who were matched for picture naming score but who differed significantly in their ability to repeat familiar words. In Experiment 1, we demonstrate that the model of naming and repetition put forward by Foygel and Dell (2000) is better able to accommodate this pattern of performance than the model put forward by Dell, Schwartz, Martin, Saffran, and Gagnon (1997). Nevertheless, Foygel and Dell's model underpredicted the repetition performance of both patients. In Experiment 2, we attempt to simulate their performance using a new dual route model of repetition in which Foygel and Dell's model is augmented by an additional nonlexical repetition pathway. The new model provided a more accurate fit to the real-word repetition performance of both patients. It is argued that the results provide support for dual route models of auditory repetition.

OBIETTIVI: determinare i fattori associati ai ricoveri ripetuti per identificare i pazienti a rischio di riospedalizzazione entro i 30 giorni dalla dimissione. DISEGNO: analisi retrospettiva delle dimissioni nell'anno 2013 attraverso le schede di dimissione ospedaliera (SDO). 3.900 pazienti ricoverati presso il presidio ospedaliero "Fabrizio Spaziani" di Frosinone. PRINCIPALI MISURE DI OUTCOME: analisi bivariata per l'analisi dell'associazione tra variabili. La regressione logistica è stata utilizzata per identificare i fattori di rischio associati al ricovero ripetuto. RISULTATI: tra i 3.900 pazienti considerati, il 12,8% ha avuto una riammissione non programmata entro un mese dalla dimissione precedente per le stesse categorie diagnostiche principali (MCD). Sono state rilevate differenze statisticamente significative tra i pazienti con e senza ricovero ripetuto per età, durata della degenza, titolo di studio, condizione occupazionale e diagnosi. I fattori che aumentano la probabilità di una riospedalizzazione sono il vivere da solo, la condizione di pensionato o casalinga, una degenza più lunga e alcune diagnosi, fra cui malattie dell'apparato respiratorio, del sistema nervoso e dell'apparato urinario. CONCLUSIONE: alcune caratteristiche sociodemografiche e la diagnosi dei pazienti ospedalizzati sono associate al rischio di riospedalizzazione entro 30 giorni dalla dimissione. I dati disponibili nell'archivio delle SDO possono essere utilizzati per un'identificazione dei pazienti a rischio sui quali definire specifici piani di dimissione.

Dell, Michael; Rollins, Kevin

2005-03-01

The success of Dell--it provides extraordinary rewards to shareholders, it can turn on a dime, and it has demonstrated impeccable timing in entering new markets--is based on more than its famous business model. High expectations and disciplined, consistent execution are embedded in the company's DNA. "We don't tolerate businesses that don't make money," founder Michael Dell tells HBR. "We used to hear all sorts of excuses for why a business didn't make money, but to us they all sounded like 'The dog ate my homework.' We just don't accept that." In order to double its revenues in a five-year period, the company had to adapt its execution-obsessed culture to new demands. In fact, Michael Dell and CEO Kevin Rollins realized they had a crisis on their hands."We had a very visible group of employees who'd gotten rich from stock options," Rollins says. "You can't build a great company on employees who say, 'If you pay me enough, I'll stay.'" Dell and Rollins knew they had to reignite the spirit of the company. They implemented an employee survey, whose results led to the creation of the Winning Culture initiative, now a top operating priority at Dell. They also defined the Soul of Dell: Focus on the customer, be open and direct in communications, be a good global citizen, have fun in winning. It turned outto be a huge motivator. And they increased the focus on developing people within the company. "We've changed as individuals and as an organization," Rollins says. "We want the world to see not just a great financial record and operational performance but a great company. We want to have leaders that other companies covet. We want a culture that makes people stick around for reasons other than money."

Case Series in Cognitive Neuropsychology: Promise, Perils and Proper Perspective

PubMed Central

Rapp, Brenda

2012-01-01

Schwartz & Dell (2010) advocated for a major role for case series investigations in cognitive neuropsychology. They defined the key features of this approach and presented a number of arguments and examples illustrating the benefits of case series studies and their contribution to computational cognitive neuropsychology. In the Special Issue on “Case Series in Cognitive Neuropsychology” there are six commentaries on Schwartz and Dell (2010) as well as a response to the six commentaries by Dell and Schwartz. In this paper, I provide a brief summary of the key points made in Schwartz and Dell (2010) and I review the promise and perils of case series design as revealed by the six commentaries. I conclude by placing the set of papers within a broader perspective, providing some clarification of the historical record on case series and single case approaches, raising some cautionary notes for case series studies and situating both case series and single case approaches within the larger context of theory development in the cognitive sciences.

La Torre dei Venti domina l’angolo Sud Ovest del cortile della Pigna (nell'area dei Musei Vaticani), ed è inclusa negli ambienti dell'Archivio Segreto Vaticano. Non è aperta al pubblico, ma è universalmente nota per la fama che da oltre quattrocento anni la circonda, legata alle vicende della riforma Gregoriana del calendario. La meridiana tracciata da padre Egnazio Danti (1536-1586) nella torre dei Venti, fu visitata anche da Gregorio XIII, probabilmente il 21 marzo 1581 come suppone il padre Stein, per convincersi dell'anticipo ormai arrivato a dieci giorni dell'equinozio di primavera sulla data che il concilio di Nicea aveva fissato al 21 marzo per il computo pasquale. La ricognizione astrometrica del febbraio-marzo 2009 fatta dall'autore viene qui presentata.

We are able to draw on both new and existing observational data for both imaging and spectroscopy. Since the ionization range of the Orion Nebula is quite low, we use the high signal-to-noise ratio (S/N) F658N and F502N images in our analysis Our new imaging observations were made with Hubble Space Telescope (HST)'s WFC3 as part of program GO 12543. Observations were made (2012 January 7) with the narrowband emission line filters F487N (Hβ409s), F502N ([OIII]348s), F656N (Hα349s), F658N ([NII]602s), and F673N ([SII]700s), in addition to observations with the continuum sampling intermediate-width filter F547M (348s). The characteristics of these filters and their calibration have been described by O'Dell et al. (2013AJ....145...92O). The images are the highest angular resolution (0.04''/pixel sampling) optical images of a portion of the Huygens Region. When used alone, we employed the original images in combination with one another. When used for comparison with earlier (undersampled) WFPC2 images (0.0996''/pixel), we processed them with IRAF task "Gauss" to match their broader image cores. We have been able to use earlier HST observations made with the WFPC2 (program GO 5085 (FOV5) on MJD49737; program GO 5469 on MJD49797; program GO 11038 (FOV1) on MJD54406; program GO 12543 on MJD55935). The most useful data set of spectra is the compilation of north-south orientation long-slit spectra by Garcia-Diaz et al. (2008RMxAA..44..181G). In addition to their original observations (Garcia-Diaz & Henney, 2007AJ....133..952G) in low-ionization lines, they recalibrate the high-ionization spectra of Doi et al. 2004 (cat. J/AJ/127/3456) and present combined results for emission lines from a wide variety of ionization states ([OI]630.0nm, [SII]671.6nm+673.1nm, [NII]658.4nm, [SIII]631.2nm, Hα656.3nm, [OIII]500.7nm) calibrated to 2km/s accuracy and a resolution of about 10km/s. We will refer to this as the Spectroscopic Atlas, or simply the Atlas. New observations were made at

The effect of speaking rate on serial-order sound-level errors in normal healthy controls and persons with aphasia.

PubMed

Fossett, Tepanta R D; McNeil, Malcolm R; Pratt, Sheila R; Tompkins, Connie A; Shuster, Linda I

Although many speech errors can be generated at either a linguistic or motoric level of production, phonetically well-formed sound-level serial-order errors are generally assumed to result from disruption of phonologic encoding (PE) processes. An influential model of PE (Dell, 1986; Dell, Burger & Svec, 1997) predicts that speaking rate should affect the relative proportion of these serial-order sound errors (anticipations, perseverations, exchanges). These predictions have been extended to, and have special relevance for persons with aphasia (PWA) because of the increased frequency with which speech errors occur and because their localization within the functional linguistic architecture may help in diagnosis and treatment. Supporting evidence regarding the effect of speaking rate on phonological encoding has been provided by studies using young normal language (NL) speakers and computer simulations. Limited data exist for older NL users and no group data exist for PWA. This study tested the phonologic encoding properties of Dell's model of speech production (Dell, 1986; Dell,et al., 1997), which predicts that increasing speaking rate affects the relative proportion of serial-order sound errors (i.e., anticipations, perseverations, and exchanges). The effects of speech rate on the error ratios of anticipation/exchange (AE), anticipation/perseveration (AP) and vocal reaction time (VRT) were examined in 16 normal healthy controls (NHC) and 16 PWA without concomitant motor speech disorders. The participants were recorded performing a phonologically challenging (tongue twister) speech production task at their typical and two faster speaking rates. A significant effect of increased rate was obtained for the AP but not the AE ratio. Significant effects of group and rate were obtained for VRT. Although the significant effect of rate for the AP ratio provided evidence that changes in speaking rate did affect PE, the results failed to support the model derived predictions

In the Mediterranean region, goat milk production is an important economic activity. In the present study, 4 casein genes were genotyped in 5 Sicilian goat breeds to 1) identify casein haplotypes present in the Argentata dell'Etna, Girgentana, Messinese, Derivata di Siria, and Maltese goat breeds; and 2) describe the structure of the Sicilian goat breeds based on casein haplotypes and allele frequencies. In a sample of 540 dairy goats, 67 different haplotypes with frequency >or=0.01 and 27 with frequency >or=0.03 were observed. The most common CSN1S1-CSN2-CSN1S2-CSN3 haplotype for Derivata di Siria and Maltese was FCFB (0.17 and 0.22, respectively), whereas for Argentata dell'Etna, Girgentana and Messinese was ACAB (0.06, 0.23, and 0.10, respectively). According to the haplotype reconstruction, Argentata dell'Etna, Girgentana, and Messinese breeds presented the most favorable haplotype for cheese production, because the casein concentration in milk of these breeds might be greater than that in Derivata di Siria and Maltese breeds. Based on a cluster analysis, the breeds formed 2 main groups: Derivata di Siria, and Maltese in one group, and Argentata dell'Etna and Messinese in the other; the Girgentana breed was between these groups but closer to the latter.

I servizi sono oramai centrali nella vita sociale di ogni Paese. L'aspettativa di ogni attore sociale, sia esso cittadino/utente e/o istituzione, è quella di ricevere da uno scambio che ha alla base un servizio un contributo che si caratterizza per una qualità intrinseca. Il mantenimento di tale promessa richiede all'azienda erogatrice un forte coinvolgimento, nel disegno del servizio, degli utenti ed una capacità di gestione della conoscenza; ciò è particolarmente significativo per quei servizi che si caratterizzano per una forte personalizzazione o complessità progettuale. Disegnare un servizio, metterlo in produzione e gestirne l'erogazione ha una complessità variabile in base al grado di coinvolgimento dei destinati ed alle dimensioni critiche che esprimono le condizioni di fattibilità di un servizio di qualità appropriato alle attese degli utilizzatori. Ugualmente la globalizzazione dell'economia e la scarsità delle risorse ha portato l'attenzione, ai fini della sostenibilità delle condizioni sopra richiamate, di una ricerca di modelli e strumenti che permettano una valutazione e una standardizzazione dei processi di produzione ed erogazione secondo condizioni di economicità. Tali primi e sintetici elementi hanno condotto diversi attori istituzionali, grandi imprese ed università attraverso i loro centri di ricerca, ad una azione di riflessione sul grado di "ingegnerizzazione" dei processi sottesi alla erogazione dei servizi ed in particolare ai servizi che attuano le politiche dei grandi settori di base dell'economia di una Nazione: educazione, sanità, sociale, sviluppo infrastrutture ecc.

Thickness and character of regolith on mountain slopes in the vicinity of Mountain Lake, Virginia, as indicated by seismic refraction, and implications for hillslope evolution

NASA Astrophysics Data System (ADS)

Mills, Hugh H.

1990-06-01

Seismic refraction was used to determine the variation in thickness and seismic velocities of regolith on boulder-mantled mountain flanks underlain by shale in the Valley and Ridge province near Mountain Lake, southwestern Virginia. Emphasis was on cross-slope variations, particularly the difference between dells (hollows) and noses. Four types of material were distinguished on the basis of seismic velocity. Soil material within 1-2 m of the ground surface affected by pedogenesis had a velocity generally less than 400 m/s. Unconsolidated bouldery colluvium, up to 6 m thick, had a velocity of about 400-800 m/s. Old, weathered and consolidated colluvium had a velocity of 800-2000 m/s. Bedrock residuum and highly weathered bedrock showed similar velocities, however, so that all material in this range was collectively termed "weathered regolith." Its thickness exceeded 30 m in places. Relatively unweathered bedrock showed velocities of at least 2000 m/s. On average, seismic profiles showed regolith thicknesses in excess of 10 m, the greater part being residuum or weathered bedrock. This finding contrasts with one study near the glacial border in Pennsylvania, which showed that colluvium generally directly overlies bedrock. This difference may reflect less-intense Pleistocene periglacial erosion in Virginia than in Pennsylvania. Topography generally was not a good predictor of regolith thickness. Hollows showed greater thicknesses of ypung colluvium than did noses, but dells and noses showed little difference in total regolith thickness. Both dells and noses showed great variation in regolith thickness. The largest systematic difference was found between dell floors (or parts thereof) that seemed to be undergoing long-term downcutting and those that appeared to be relict features no longer associated with active drainageways. The former were underlain by a mean of 5.5 m of weathered regolith, whereas the latter were underlain by a mean of 14.0 m, indicative of a greater

Geology of Tompkins Hill gas field, Humboldt County, California

DOE Office of Scientific and Technical Information (OSTI.GOV)

Parker, J.

1988-03-01

The Tompkins Hill gas field, located in Humboldt County, California, is the only producing field in the Eel River basin. The field is an anticlinal flexure on the north limb of the Eel River syncline in the central onshore portion of the basin. The Tompkins Hill anticline is doubly plunging and trends east-west. Stratigraphic units present in the field include the Yager, Eel River, and Rio Dell Formations and Scotia Bluffs Sandstone. The Yager occurs below a major unconformity, and forms economic basement. Strata overlying the Eel River, Rio Dell, and Scotia Bluffs represent a progradational basin-fill sequence, including submarinemore » fan, slope, shelf, and littoral deposits. The primary productive interval in the field is within the middle of the Rio Dell and consists of interbedded fine sandstone and mudrock. Portions of the Eel River and upper Rio Dell Formations are also productive. The Tompkins Hill gas field was discovered by the Texas Company in 1937 with the drilling of Eureka 2 in Sec. 22, T3N, R1W. The play was probably based on outcrop mapping and the presence of gas seeps in the area. The primary trapping mechanism in the field is structural, although stratigraphy may have been a factor in constraining gas. To date, 39 producing wells have been drilled and 87.4 bcf of gas, consisting of 98% methane, has been produced. Very minor amounts of condensate are also produced. The source rocks for the gas are uncertain, but both the Yager Formation and strata of the lower Wildcat Group may have contributed.« less

Why American business demands twenty-first century skills: an industry perspective.

PubMed

Bruett, Karen

2006-01-01

Public education is the key to individual and business prosperity. With a vested stake in education, educators, employers, parents, policymakers, and the public should question how this nation's public education system is faring. Knowing that recent international assessments have shown little or no gains in American students' achievement, the author asserts the clear need for change. As both a large American corporate employer and a provider of technology for schools, Dell is concerned with ensuring that youth will thrive in their adult lives. Changing workplace expectations lead to a new list of skills students will need to acquire before completing their schooling. Through technology, Dell supports schools in meeting educational goals, striving to supply students with the necessary skills, referred to as twenty-first century skills. The Partnership for 21st Century Skills, of which Dell is a member, has led an initiative to define what twenty-first century learning should entail. Through extensive research, the partnership has built a framework outlining twenty-first century skills: analytical thinking, communication, collaboration, global awareness, and technological and economic literacy. Dell and the partnership are working state by state to promote the integration of these skills into curricula, professional development for teachers, and classroom environments. The authors describe two current initiatives, one in Virginia, the other in Texas, which both use technology to help student learning. All stakeholders can take part in preparing young people to compete in the global economy. Educators and administrators, legislators, parents, and employers must play their role in helping students be ready for what the workforce and the world has in store for them.

In questo contributo verrà discussa l'importanza dei dischi e jet ad essi asso- ciati per la formazione delle stelle di tipo spettrale OB e verranno presentati i risultati recentemente ottenuti con ALMA in questo ambito. In particolare mostr- eremo che la struttura del disco sembra risentire della complessità dell'ambiente circostante e che la probabilità di rivelare un disco attorno alle stelle di più alta massa è massima in una fase evolutiva intermedia. Infine discuteremo la possibilità che il fenomeno di accrescimento dal disco sulla stella possa avvenire in maniera discontinua mediante "burst", probabilmente dovuti ad instabilità nel disco.

INTRODUZIONE: una vasta area compresa tra le province di Napoli e Caserta nella regione Campania ha negli ultimi anni attirato l'attenzione dei mass media a causa degli interramenti illeciti di rifiuti di varia origine nei campi o del loro abbandono lungo le strade. A tali pratiche illecite si aggiunge il fenomeno dei roghi incontrollati di questo materiale, motivo per il quale la zona è stata soprannominata "Terra dei fuochi". OBIETTIVI: ricerca di elementi in tracce presenti nei prodotti alimentari di origine vegetale prodotti nella Terra dei fuochi. DISEGNO E SETTING: piano di monitoraggio per il rilevamento dei livelli di alcuni metalli tossici ed essenziali nei vegetali coltivati in Campania nella Terra dei fuochi. La determinazione dei microelementi è stata effettuata dopo mineralizzazione della sostanza organica mediante microonde, utilizzando la spettrometria di massa a plasma induttivamente accoppiato (ICP-MS). RISULTATI: durante l'attività di monitoraggio sono stati raccolti 65 campioni di ortaggi e 49 campioni di frutta in 43 comuni rientranti nella Terra dei fuochi. Il contenuto medio di metalli tossici, cadmio e piombo nei prodotti ortofrutticoli è risultato ben lontano dai limiti massimi fissati dalla normativa europea. I valori delle concentrazioni sono significativamente inferiori rispetto a quanto riscontrato in zone ad alto impatto ambientale a causa della presenza di impianti industriali. CONCLUSIONI: la presenza di elementi tossici o potenzialmente tali nei campioni vegetali prodotti nella Terra dei fuochi è attribuibile a una varietà di fattori ambientali rilevanti (caratteristiche geologiche dell'area, inquinamento del suolo, dell'atmosfera e delle acque di irrigazione, pratiche illecite di smaltimento dei rifiuti industriali); non sembra, tuttavia, sussistere un rischio per la salute dei consumatori. Resta comunque l'allerta per la loro presenza nell'ambiente e la necessità che le attività di monitoraggio continuino.

Infantile myofibromatosis (IM) is a nonmetastasizing locally invasive neoplasm. The behavior of the tumor is more hamartomatous than tumoral, and it is unclear whether the cell of origin is a fibroblast or a smooth muscle myocyte. Lesions typically present during infancy and range in size from a few millimeters to several centimeters. We present an unusual case of a patient with an atrophic variant of IM.

Il dato dell'Organizzazione per la cooperazione e lo sviluppo economico (OCSE) del 2012, che indicava l'Italia come il Paese con la più bassa spesa in prevenzione sanitaria, ha dato lo spunto per una raccolta sistematica e un'analisi critica dei flussi disponibili sulla spesa per le attività di prevenzione in Italia. Le statistiche correnti di spesa sanitaria sono raccolte centralmente dall'Agenzia nazionale per i servizi sanitari regionali (Agenas) attraverso i modelli di rilevazione dei costi dei livelli essenziali di assistenza (LEA) delle aziende USL. Le tre macroaree dei LEA sono: assistenza distrettuale, assistenza ospedaliera e assistenza sanitaria collettiva in ambiente di vita e di lavoro. Le spese per la prevenzione rientrano in quest'ultima e sono ripartite nelle seguenti voci: attività di prevenzione rivolte alle persone, igiene degli alimenti e della nutrizione, igiene e sanità pubblica, prevenzione e sicurezza negli ambienti di lavoro, sanità pubblica veterinaria, attività medico-legale per finalità pubblica. Tra il 2006 e il 2013, ultimo dato disponibile, la spesa per le attività di prevenzione del Servizio sanitario nazionale (SSN) è rimasta costante in rapporto alla spesa sanitaria totale (4,2%), pari a 4,9 miliardi nel 2013. Nel periodo di studio considerato (2006-2013) appaiono in aumento le spese per le attività rivolte alle persone (+8,7%), attribuibili soprattutto a vaccinazioni e screening, e in diminuzione le attività di igiene pubblica (-5,7%) e quelle della sanità pubblica veterinaria (-3,8%). I confronti internazionali indicano una spesa per la prevenzione del 2,9% rispetto alla spesa sanitaria totale, costante negli anni e nella media dei Paesi OCSE. Per la prevenzione, l'Italia spende tanto quanto i Paesi che non possiedono un servizio sanitario pubblico; il dato risulta inferiore del 5% rispetto alla programmazione nazionale, con poche eccezioni e molta variabilità regionale all'interno delle componenti delle voci di spesa

Research contributions on childhood obesity from a public-private partnership

PubMed Central

2015-01-01

Background Childhood obesity remains a significant global problem with immediate and long-term individual health and societal consequences. Targets for change should include the most potent and predictive factors for obesity at all levels of the personal, social and physical environments. The Michael & Susan Dell Center for Healthy Living (‘the Center’) is a public-private partnership that was developed to address child health issues through research, service, and education. This overview paper introduces a special issue of seven articles on childhood obesity from the Center, and the implications of this research for obesity prevention. Methods and results A review of the literature on public-private partnerships was undertaken and key components of the partnership between the Michael & Susan Dell Foundation and the Center were compared for compatibility. The conceptual framework for Center research, based on social cognitive theory and the social-ecological model, is explained. An overview of papers in this special issue, relative to the conceptual framework, and the implications of this research for childhood obesity prevention, are provided. Conclusions The public-private partnership that created the Michael & Susan Dell Center for Healthy Living has been instrumental in motivating the Center’s academic faculty to focus their research on improvements in child, family and community health through etiologic, epidemiologic, methodologic and intervention research. This special issue extends this work and places particular emphasis on socioeconomic inequalities in addressing the obesity problem in the U.S. and worldwide. PMID:26222489

In 2012 a manuscript was rediscovered in the Biblioteca dell'Archiginnasio of Bologna, titled Libro degli infermi dell'Arciconfraternita di S. Maria della Morte. It is the record of incoming patients of one for the main hospitals of the city, devoted exclusively to the sick poor and not just to the poor, called Santa Maria della Morte, compiled by a young student assistant (astante) for the period 1558-1564. I publish here a transcription of a portion of this Libro pertaining to the year 1560. My introduction situates the manuscript within the context of the history of early modern Italian hospitals, describes the organization of the hospital of Santa Maria della Morte based on archival sources of the period, and finally highlights the connections between surgical and anatomical education and the internal organization of the hospital.

The rhythms of progression and retraction of the polar ice caps on Mars have been studied to establish possible variations in polar meteorology over the course of the last centuries. The applied theoretical procedure offers a mathematical function that contains some significant physical parameters, for example the length and the beginning of spring and another parameter which depends on temperature. The numerical data for the South Polar Cap during the grand oppositions of the last 130 years has been studied with the suggested theory. Evident correlations emerge between parameters and form of the diagram of cap amplitude versus time.

Modular properties of 6d (DELL) systems

NASA Astrophysics Data System (ADS)

Aminov, G.; Mironov, A.; Morozov, A.

2017-11-01

If super-Yang-Mills theory possesses the exact conformal invariance, there is an additional modular invariance under the change of the complex bare charge [InlineMediaObject not available: see fulltext.]. The low-energy Seiberg-Witten prepotential ℱ( a), however, is not explicitly invariant, because the flat moduli also change a - → a D = ∂ℱ/∂ a. In result, the prepotential is not a modular form and depends also on the anomalous Eisenstein series E 2. This dependence is usually described by the universal MNW modular anomaly equation. We demonstrate that, in the 6 d SU( N) theory with two independent modular parameters τ and \\widehat{τ} , the modular anomaly equation changes, because the modular transform of τ is accompanied by an ( N -dependent!) shift of \\widehat{τ} and vice versa. This is a new peculiarity of double-elliptic systems, which deserves further investigation.

Measuring lead in the surface dental enamel (SDE) using biopsies is a rapid, safe, and painless procedure. The dental enamel lead levels (DELLs) decrease from the outermost superficial layer to the inner layer of dental enamel, which becomes crucial for the biopsy depth (BD) measurement. However, whether the origin of lead found in SDE is fully endogenous is not yet established. There is also controversy about the biopsy protocol. The aims of this study were to investigate if DELLs are altered by extrinsic contamination (A) and to evaluate the real geometric figure formed by the erosion provoked by biopsy procedure and the respective BD in SDE (B). To accomplish the aim A, lead from 90 bovine incisor crowns lead was determined by graphite furnace atomic absorption spectrometer as a function of exposure time and lead concentration. Two biopsies were performed in each tooth, before and after lead exposure. Six 15-tooth groups differed by exposure time (1 or 30 min) and lead concentrations (A. 0 mg/L-placebo, B. 0.01 mg/L-standard for drinking water, or C. 0.06 mg/L-concentration found in contaminated groundwater). Phosphorus was determined by an inductively coupled plasm optical emission spectrometer to quantify the enamel removed. To compare intakes/losses of lead in SDE among the groups, values of DELL differences between before and after lead exposure were compared by ANOVA (p < 0.05). To attain the objective B, one extracted human permanent tooth was studied by confocal Raman microscopy. Lead measurements and the surface profile were determined. There was no difference in DELL among the groups (p = 0.964). The biopsy bottom surface area, analyzed by microscopy, showed an irregular area, with regions of peaks and valleys, where areas with depth ranging from 0.2 (peaks) to 1.8 μm (valleys) (± 0.1 μm) could be found. BD carried out in vivo is commonly calculated using the cylinder height formula. The real BD was shown to be very similar to already

PubMed

Ravelli, A

1975-06-01

The basic shape of the facies lunata shows at the inner margin of each of the three participating bones a dell into which the floor of the acetabulum progresses. These dells originate in nutritive vessels which enter the bone and claim this place. There always are groups of vessels and wide channels which may be visible on radiographs. The so far unexplained picture of a vascular canal in the roof of the acetabulum corresponds to the canal leading into the body of the ilium. Due to its position there is often restructuring leading to filling or covering of the canal. The entrance to this canal is shown as a gap in the arc of the acetabular cavity which would have to be added to that of the "tear figure" known so far. The closed arc, as always drawn, reults only when this entry has been filled up.

INTRODUZIONE: sebbene la relazione causale tra esposizione ad amianto e malattie neoplastiche sia ben nota, in molti Paesi il consumo del materiale è ancora rilevante e crescente. A causa della lunga latenza, nei Paesi dove è stato bandito (come in Italia) è oggi in corso un'epidemia di malattie correlate ad amianto. OBIETTIVI: descrivere i sistemi di sorveglianza dei mesoteliomi attivi nel mondo mediante un'analisi comparativa. è stata condotta una revisione bibliografica della letteratura disponibile sui sistemi di sorveglianza epidemiologica dei mesoteliomi attivi nel mondo, comparando metodi e risultati disponibili. RISULTATI: sistemi di ricerca dei casi incidenti e di analisi anamnestica dei soggetti ammalati sono attivi solo in Italia, Francia e Corea del Sud. I Paesi presso i quali sono attivi sistemi di rilevazione e controllo dei casi incidenti di mesotelioma sono quelli in cui vige il bando dell'amianto e che hanno sperimentato consumi rilevanti in passato. Non sono stati istituiti sistemi epidemiologici di sorveglianza in molti Paesi dove il consumo di amianto è ancora importante (inclusi Russia, Cina, India e Brasile). CONCLUSIONI: si conferma l'importanza dei sistemi di sorveglianza epidemiologica dei mesoteliomi per la sanità pubblica, il sostegno alle politiche di welfare e la prevenzione dei rischi. Lo sviluppo di progetti per tendere a una maggiore uniformità nei metodi di ricerca dei casi, di classificazione delle diagnosi e dell'esposizione e nelle tecniche di analisi dei dati potrebbe consentire una maggiore fruibilità dei dati aggregati. La disponibilità di dati internazionali confrontabili può essere di stimolo all'adozione di provvedimenti di bando internazionale.

Sparking controversy: Jean Antoine Nollet and medical electricity south of the Alps.

PubMed

Bertucci, Paola

2005-01-01

The paper considers a significant episode in the history of eighteenth-century electricity: the controversy over the "medicated tubes". Invented by the Italian erudite Gianfrancesco Pivati, the tubes were said to produce instantaneous cures. Jean Antoine Nollet was one of the main actors of the controversy. In 1749, after touring Italy to see for himself the Italian tubes and their effects, he published a report, discrediting Pivati's accounts. This study shows that the report, which has since been the main source for interpretations of the controversy, hides the key role of the Bologna Istituto delle Scienze in promoting Pivati's invention. Relying on manuscript sources, I propose a change of perspective on the controversy that illuminates the world of Italian experimental philosophy during the Enlightenment and its place in the Republic of Letters. I also analyze the reasons for Nollet's silence over the involvement of the Istituto delle Scienze in the controversy and the relevance of medical electricity in the wider context of contemporary electrical experimental philosophy.

THE FORMATION OF MACROCYTES AND MICROCYTES FROM RED CORPUSCLES IN HANGING DROP PREPARATIONS

PubMed Central

Auer, John

1932-01-01

In hanging drop preparations of normal blood from various species of animals including man, the following processes were directly observed for the first time: 1. The process of fusion between two red corpuscles so as to form a round or slightly oval macrocyte with normal hemoglobin content, a diameter of 10µ± and no delle. These macrocytes appear to be slightly thicker in the centre than at the periphery. No thickness measurements could be made. 2. The process of fusion between two microcytes each 5µ± in diameter, so as to form a red corpuscle of approximately normal size but with dense hemoglobin and no delle. 3. The process of fusion between a red corpuscle and a microcyte, forming a macrocyte slightly larger than a normal red corpuscle and exhibiting a normal hemoglobin tint but no delle. 4. The process of microcyte formation from red corpuscles was seen occurring in four different ways: (a) By the intermittent compression of a single red corpuscle by the pull of three or more fibrin threads attached to the corpuscle. (b) By the steady, continuous compression of a single red corpuscle by the pull of two polar fibrin threads, (c) By intermittent rises of intracorpuscular pressure in a red corpuscle due to trauma, (d) By avulsion and retraction or contraction of the hemoglobin stroma from the intact surface layer of a red corpuscle. Thickness measurements in single microcytes were made in rabbit blood. 5. The process of a typical microcyte with dense hemoglobin and no delle changing back to a fairly large red corpuscle with practically normal hemoglobin tint and with a delle. 6. Macrocytes were seen expelling their hemoglobin in a fraction of a second and turning into shadows which were often paler than the background, but without any decrease in the visible surface area or change in the contour. 7. Extensibility and retractibility (or perhaps relaxation and contraction) may be exhibited by the corpuscle as a whole, by local sections of both surface layer and

Meningococco B: controllo di due focolai epidemici mediante vaccinazione

PubMed Central

2014-01-01

Riassunto La problematica di un efficace approccio vaccinale nei confronti del Meningococco B (MenB) è stata superata identificando con la metodica della "reverse vaccinology" alcuni antigeni capaci di indurre una risposta verso la maggior parte dei ceppi di MenB circolanti nel mondo. Il nuovo vaccino MenB a 4 componenti (4CMenB) è stato autorizzato in Europa, Australia e Canada, ed è entrato nei calendari di immunizzazione pediatrica internazionali: Australia, Canada, UK. In Italia, le prime regioni che hanno raccomandato la vaccinazione contro il MenB sono state Basilicata e Puglia. La gestione di epidemie/focolai epidemici richiede la messa in atto di una risposta rapida da parte delle autorità sanitarie nei confronti di una emergenza sanitaria ad elevato impatto, anche emotivo, sulla popolazione, come recentemente dimostrato in due università americane. Alla dichiarazione di focolaio epidemico in atto, in entrambi i contesti si è attivata una procedura per l'uso del vaccino 4CMenB non ancora autorizzato negli USA. È stato così possibile organizzare gli interventi di profilassi attiva nei due campus universitari, adottando il primo impiego su larga scala del nuovo vaccino 4CMenB e conseguendo, in tempi relativamente brevi, elevati tassi di copertura vaccinale. A fronte di circa 14000 studenti immunizzati con almeno una dose, non è stata segnalata alcuna problematica di eventi avversi conseguenti all'immunizzazione; ad oggi non si sono verificati casi nei soggetti che hanno ricevuto il vaccino. Come conseguenza dei due focolai descritti, è oggi in corso la valutazione da parte dell'FDA per l'estensione dell'uso del vaccino 4CMenB negli Stati Uniti negli adolescenti e giovani adulti.

On the sides of the chair of St. Hyppolitus in the Vatican Libray there is a series of 112 epacts, used for calculating the date of Christian Easter valid for 112 years from 222 AD. The algorithm of octaëteris or 8 civil (julian) years=99 lunar months and a correction of three days each 16 years or one day each 5, 5, 6 years are discussed. Four complete solar cycles (28 years), after which the sequence of the day of the week are repeating, are included in 112 years as well as 7 groups of 16 years; 112 is the minimum common multiple between the double octaëteris (16 years) and the solar cycle (28).

Who did invent the telescope? It seems a simple-answering question but this is untrue. The article recall the fundamental steps of the first phase in the telescope history between 16th and 17th century, from the first experiences with the lenses made by the Italian opticians to the Della Porta's theories, from the vicissitudes of the Dutch spectacle-makers to the spreading of the new instrument through the European squares. At last we meet the work of Galileo Galilei, the first man to use the telescope for scientific purposes, understanding all its potentialities.

Refining age estimates for three historic ground rupturing earthquakes in the Santa Cruz Mountains: 14C Wiggle-matching and Non-Native Pollen as age indicators (or not!)

NASA Astrophysics Data System (ADS)

Streig, A. R.; Weldon, R. J.; Dawson, T. E.; Guilderson, T.; Gavin, D. G.; Reidy, L.

2013-12-01

The Hazel Dell site provides the first definitive paleoseismic evidence of two pre-1906 19th century events on the Santa Cruz Mountains section based on the presence of anthropogenic artifacts. Hundreds of pieces of cut redwood chips were found in a stratigraphic horizon just below the ante-penultimate (E3) earthquake surface, suggesting that redwood trees at the site were cut down right before earthquake E3. We correlate our paleoseismic findings with the historic record and the onset of redwood logging in the area by determining the felling date of a buried redwood tree stump at the site and the age of the woodchips. We wiggle match 14 radiocarbon dates sampled from annual growth rings taken from the stump and the known interval between growth rings, with the intercepts of the INTCAL04 terrestrial 14C calibration curve. Pending 13C measurements, we find that the youngest ring we have identified in the tree is A.D. 1800. We also wiggle match 2 radiocarbon dates from inner and outer growth rings from two wood chips (with bark); their ages are consistent with the tree and the youngest woodchip ring is dated to 1813 A.D. There are no known ethnographic or historical accounts of pre-contact native people felling large trees in the way that European colonists did. The first record of European land use was for pasture in 1803. The property became a Spanish land grant in 1827, soon after which a whip-saw lumber mill is documented to have begun operation in the upper Corralitos area. We combine these paleoseismic results with historical earthquake accounts for the area and conclude that the San Andreas fault ruptured in 1838, 1890 and 1906. The Hazel Dell results are in contrast with findings from earlier paleoseismic studies in the Santa Cruz Mountains. The Grizzly Flat site, 6 km to the north, found evidence of 1906 and one 17th century earthquake. Two historic earthquakes were observed at the Mill Canyon site 8 km to the south and at the Arano Flat site 9.5 km south of

Tremolada, Sara; Delbue, Serena; Ferrante, Pasquale

2009-01-01

Riassunto Alcuni virus possono essere trasmessi verticalmente da madre a figlio in seguito allo sviluppo, da parte della madre, di un’infezione primaria, ricorrente o cronica. La trasmissione materno-fetale dei virus, che può avvenire in utero (infezione congenita), durante il travaglio del parto (infezione perinatale), oppure attraverso l’allattamento (infezione postnatale), può causare aborto spontaneo, morte fetale, ritardo di crescita intrauterino, anomalie congenite e patologie neonatali o postnatali di diversa entità. Alcuni fattori di rischio sembrano influenzare l’incidenza di trasmissione materno-fetale dei virus, come ad esempio la presenza di altre infezioni virali, la carica virale materna, il tipo di infezione (primaria o ricorrente), la durata della rottura delle membrane, la modalità con cui avviene il parto, le condizioni socio-economiche e l’allattamento. Oggi è possibile prevenire la trasmissione materno-fetale di molti virus grazie all’utilizzo di vaccini, immunizzazione passiva e farmaci antivirali. Il rischio di trasmissione delle infezioni perinatali e postnatali, inoltre, può essere diminuito evitando l’allattamento o ricorrendo ad un parto cesareo. PMID:19216201

The Milky Way and the Local Group

The beauty and the charm of the Milky May (MW) have been celebrated by countless poets and writers of many Countries along the centuries (see e.g. the beautiful anthology of Piero Boitani 2012 ). The stellar nature of the MW was firstly observed by Galileo. In 1610 in the Sidereus Nuncius ( Galilei 1993 ) Galileo wrote that the MW is "nient'altro che una congerie di innumerevoli Stelle, disseminate a mucchi; chè in qualunque regione di essa si diriga il cannocchiale, subito una ingente folla di Stelle si presenta alla vista, delle quali parecchi si vedono abbastanza grandi e molto distinte; ma la moltitudine delle piccole è del tutto inesplorabile". In the same paragraph, Galileo remarked that observations with his telescope, for the first time, wipe out centuries of philosophical discussions about the nature of the MW. Three more centuries have been necessary to complete a second radical Copernican Revolution that displaces the solar system from being roughly at the center of the MW and project this latter in the vast Universe populated by billions of similar spiral galaxies (see Chap. 1).

RIASSUNTO. L'elaborazione del piano di trattamento rappresenta un momento molto delicato e complesso del processo terapeutico del disturbo da abuso di alcol (DUA). È la fase in cui le informazioni raccolte da un'équipe di professionisti (medici, psicologi e assistenti sociali) (modello bio-psico-sociale del DUA) vengono messe insieme per decidere il percorso terapeutico più adatto. Per quanto riguarda la parte psicologica, è di notevole importanza scegliere un trattamento clinico in grado di ridurre al minimo la mancata adesione al trattamento e, per i soggetti che rimangono in trattamento, di garantirne l'efficacia. Se da una parte, le tecniche psicoanalitiche e comportamentali hanno fornito le basi della terapia psicologica dell'alcolismo, dall'altra, gli approcci basati sull'evidenza scientifica sono stati elaborati a partire dai principi del colloquio motivazionale e della terapia cognitivo-comportamentale. In questo articolo viene fornita una panoramica dei trattamenti che sono risultati più efficaci nel trattare il DUA e delle modalità temporali più adeguate per monitorare l'efficacia del trattamento.

RIASSUNTO. Gli adolescenti rappresentano la fascia di età più vulnerabile ai danni causati dall'abuso di alcol, in quanto iniziare a bere in giovane età è associato a un aumento del rischio di dipendenza da alcolici in età adulta. I giovani tendono a bere grandi quantità di alcolici al fine di ricercare forti emozioni e nel tentativo di raggiungere il divertimento a ogni costo, tramite le proprietà psicotrope degli alcolici. Le cause che li inducono ad assumere questi comportamenti sono da ricercare nella non conoscenza degli effetti dannosi dell'alcol, nel rito di convivialità sociale (evenienza per la quale si attribuisce all'alcol la funzione di facilitatore dell'aggregazione tra giovani), nella mancanza di interessi personali, nella scarsità dei controlli e nelle abitudini familiari. Le azioni da intraprendere per limitare o arrestare il consumo nocivo di alcol nei giovani si devono basare su interventi finalizzati a ritardare l'età del primo contatto con le bevande alcoliche, mediante la realizzazione di campagne educazionali rivolte ai giovani stessi, ai loro familiari e alla società intera.

Current and Future Constraints on Primordial Magnetic Fields

NASA Astrophysics Data System (ADS)

Sutton, Dylan R.; Feng, Chang; Reichardt, Christian L.

2017-09-01

We present new limits on the amplitude of potential primordial magnetic fields (PMFs) using temperature and polarization measurements of the cosmic microwave background (CMB) from Planck, the BICEP2/Keck Array, Polarbear, and SPTpol. We reduce twofold the 95% confidence upper limit on the CMB anisotropy power due to a nearly scale-invariant PMF, with an allowed B-mode power at ℓ = 1500 of {D}{\\ell =1500}{BB}< 0.071 μ {K}2 for Planck versus {D}{\\ell =1500}{BB}< 0.034 μ {K}2 for the combined data set. We also forecast the expected limits from soon-to-deploy CMB experiments (like SPT-3G, Adv. ACTpol, or the Simons Array) and the proposed CMB-S4 experiment. Future CMB experiments should dramatically reduce the current uncertainties by one order of magnitude for the near-term experiments and two orders of magnitude for the CMB-S4 experiment. The constraints from CMB-S4 have the potential to rule out much of the parameter space for PMFs.

A beam monitor based on MPGD detectors for hadron therapy

NASA Astrophysics Data System (ADS)

Altieri, P. R.; Di Benedetto, D.; Galetta, G.; Intonti, R. A.; Mercadante, A.; Nuzzo, S.; Verwilligen, P.

2018-02-01

Remarkable scientific and technological progress during the last years has led to the construction of accelerator based facilities dedicated to hadron therapy. This kind of technology requires precise and continuous control of position, intensity and shape of the ions or protons used to irradiate cancers. Patient safety, accelerator operation and dose delivery should be optimized by a real time monitoring of beam intensity and profile during the treatment, by using non-destructive, high spatial resolution detectors. In the framework of AMIDERHA (AMIDERHA - Enhanced Radiotherapy with HAdron) project funded by the Ministero dell'Istruzione, dell'Università e della Ricerca (Italian Ministry of Education and Research) the authors are studying and developing an innovative beam monitor based on Micro Pattern Gaseous Detectors (MPDGs) characterized by a high spatial resolution and rate capability. The Monte Carlo simulation of the beam monitor prototype was carried out to optimize the geometrical set up and to predict the behavior of the detector. A first prototype has been constructed and successfully tested using 55Fe, 90Sr and also an X-ray tube. Preliminary results on both simulations and tests will be presented.

Peimbert (National Autonomous University of Mexico) Credit for Large Binocular Telescope data: David Thompson (University of Arizona) ---- The Ring Nebula's distinctive shape makes it a popular illustration for astronomy books. But new observations by NASA's Hubble Space Telescope of the glowing gas shroud around an old, dying, sun-like star reveal a new twist. "The nebula is not like a bagel, but rather, it's like a jelly doughnut, because it's filled with material in the middle," said C. Robert O'Dell of Vanderbilt University in Nashville, Tenn. He leads a research team that used Hubble and several ground-based telescopes to obtain the best view yet of the iconic nebula. The images show a more complex structure than astronomers once thought and have allowed them to construct the most precise 3-D model of the nebula. "With Hubble's detail, we see a completely different shape than what's been thought about historically for this classic nebula," O'Dell said. "The new Hubble observations show the nebula in much clearer detail, and we see things are not as simple as we previously thought." The Ring Nebula is about 2,000 light-years from Earth and measures roughly 1 light-year across. Located in the constellation Lyra, the nebula is a popular target for amateur astronomers.

1963-01-01

The results of investigations of the sediment and water discharge characteristics of Black Earth Creek, Mount Vernon Creek, and Yellowstone River from 1954 to 1959 and Dell Creek for 1958 and 1959 indicate large differences in annual runoff and sediment yields. The suspended-sediment discharge of Black Earth Creek averaged 3,260 tons per year or 71 tons per square mile : the annual yields ranged from 27 to 102 tons per square mile. The annual suspended-sediment yield of Mount Vernon Creek ranged from 48 to 171 tons per square mile and averaged 96 tons per square mile. The maximum daily discharge was 1,120 tons on April 1, 1960, during a storm which produced 67 percent of the suspended load for that water year and exceeded the discharge for the preceding 3 years. The sediment discharge of the Yellowstone River averaged 6,870 tons per year or 236 tons per square riffle. The maximum daily sediment discharge, 3,750 tons on April 1, 1959, occurred during a 14-day period of high flow during which the sediment discharge was 15,480 tons. In 1958 and 1959, Dell Creek had suspended-sediment yields of 4.7 and 26 tons per square mile of drainage area. The suspended sediment transported by Black Earth and Mount Vernon Creeks is about two-thirds clay and one-third silt. For Yellowstone River the particle-size distribution of the suspended sediment ranged from three-fourths clay and one-fourth silt during periods of low sediment discharge to one-third clay and two-thirds silt during high sediment discharges. For Dell Creek nearly all of the suspended sediment is clay, but the bed load is sand. The mean sediment concentration of storm runoff averaged two to three times more in the summer than in the winter. No significant changes with time occurred in the relation between storm runoff and sediment yield.

Phonological Feature Repetition Suppression in the Left Inferior Frontal Gyrus.

Okada, Kayoko; Matchin, William; Hickok, Gregory

Models of speech production posit a role for the motor system, predominantly the posterior inferior frontal gyrus, in encoding complex phonological representations for speech production, at the phonemic, syllable, and word levels [Roelofs, A. A dorsal-pathway account of aphasic language production: The WEAVER++/ARC model. Cortex, 59(Suppl. C), 33-48, 2014; Hickok, G. Computational neuroanatomy of speech production. Nature Reviews Neuroscience, 13, 135-145, 2012; Guenther, F. H. Cortical interactions underlying the production of speech sounds. Journal of Communication Disorders, 39, 350-365, 2006]. However, phonological theory posits subphonemic units of representation, namely phonological features [Chomsky, N., & Halle, M. The sound pattern of English, 1968; Jakobson, R., Fant, G., & Halle, M. Preliminaries to speech analysis. The distinctive features and their correlates. Cambridge, MA: MIT Press, 1951], that specify independent articulatory parameters of speech sounds, such as place and manner of articulation. Therefore, motor brain systems may also incorporate phonological features into speech production planning units. Here, we add support for such a role with an fMRI experiment of word sequence production using a phonemic similarity manipulation. We adapted and modified the experimental paradigm of Oppenheim and Dell [Oppenheim, G. M., & Dell, G. S. Inner speech slips exhibit lexical bias, but not the phonemic similarity effect. Cognition, 106, 528-537, 2008; Oppenheim, G. M., & Dell, G. S. Motor movement matters: The flexible abstractness of inner speech. Memory & Cognition, 38, 1147-1160, 2010]. Participants silently articulated words cued by sequential visual presentation that varied in degree of phonological feature overlap in consonant onset position: high overlap (two shared phonological features; e.g., /r/ and /l/) or low overlap (one shared phonological feature, e.g., /r/ and /b/). We found a significant repetition suppression effect in the left

Comparison between GPR measurements and ultrasonic tomography with different inversion algorithms: an application to the base of an ancient Egyptian sculpture

NASA Astrophysics Data System (ADS)

2011-09-01

By late 2008 one of the most important pieces of the 'Museo delle Antichità Egizie' of Turin, the sculpture of the Pharaoh with god Amun, was planned to be one of the masterpieces of a travelling exhibition in Japan. The 'Fondazione Museo delle Antichità Egizie di Torino', who manages the museum, was concerned with the integrity of the base of the statue which actually presents visible signs of restoration dating back to the early 19th century. It was required to estimate the persistence of the visible fractures, to search for unknown ones and to provide information about the overall mechanical strength of the base. To tackle the first question a GPR reflection survey along three sides of the base was performed and the results were assembled in a 3D rendering. As far as the second question is concerned, two parallel, horizontal ultrasonic 2D tomograms across the base were made. We acquired, for each section, 723 ultrasonic signals corresponding to different transmitter and receiver positions. The tomographic data were inverted using four different software packages based upon different algorithms. The obtained velocity images were then compared each other, with the GPR results and with the visible fractures in the base. A critical analysis of the comparisons is finally presented.

Teleportation of squeezing: Optimization using non-Gaussian resources

DOE Office of Scientific and Technical Information (OSTI.GOV)

Dell'Anno, Fabio; De Siena, Silvio; Illuminati, Fabrizio

2010-12-15

We study the continuous-variable quantum teleportation of states, statistical moments of observables, and scale parameters such as squeezing. We investigate the problem both in ideal and imperfect Vaidman-Braunstein-Kimble protocol setups. We show how the teleportation fidelity is maximized and the difference between output and input variances is minimized by using suitably optimized entangled resources. Specifically, we consider the teleportation of coherent squeezed states, exploiting squeezed Bell states as entangled resources. This class of non-Gaussian states, introduced by Illuminati and co-workers [F. Dell'Anno, S. De Siena, L. Albano, and F. Illuminati, Phys. Rev. A 76, 022301 (2007); F. Dell'Anno, S. Demore » Siena, and F. Illuminati, ibid. 81, 012333 (2010)], includes photon-added and photon-subtracted squeezed states as special cases. At variance with the case of entangled Gaussian resources, the use of entangled non-Gaussian squeezed Bell resources allows one to choose different optimization procedures that lead to inequivalent results. Performing two independent optimization procedures, one can either maximize the state teleportation fidelity, or minimize the difference between input and output quadrature variances. The two different procedures are compared depending on the degrees of displacement and squeezing of the input states and on the working conditions in ideal and nonideal setups.« less

Leonardo da Vinci's Manuscript D consists of five double pages sheets, which, folded in two, comprise ten folios. This document, in the old Tuscan dialect and mirror writing, reveals the ideas of Leonardo on the anatomy of the eye in relation to the formation of images and visual perception. Leonardo explains in particular the behavior of the rays in the eye in terms of refraction and reflection, and is very mechanistic in his conception of the eye and of the visual process. The most significant innovations found in these folios are the concept of the eye as a camera obscura and the intersection of light rays in the interior of the eye. His texts nevertheless show hesitation, doubts and a troubled confusion, reflecting the ideas and uncertainties of his era. He did not share his results in his lifetime, despite both printing and etching being readily available to him.

The "Fondazione Museo delle Antichità Egizie di Torino", managing the museum, was concerned with the integrity of the basement of the statue which actually presents visible signs of restorations dating back to the early IXX century. The questions put by the museum managers were to estimate the internal extension of some visible fractures, to search for unknown internal ones and to provide information about the overall mechanical strength of the basement. In order to tackle the first and second questions a GPR reflection survey of the basement along three sides was performed and the results were assembled in a 3D rendering. As far as the third question is concerned, two parallel, horizontal ultrasonic 2D tomographies across the basement were made with a source-receiver layout able to acquire, for each section, 723 ultrasonic signals correspondent to different transmitter and receiver positions. The ultrasonic tomographic data were inverted using different software based upon different algorithms. The obtained velocity images were then compared with the GPR results and with the visible joints on the basement. A critical analysis of the comparisons is finally presented.

In the framework of the National Project “Sviluppo di distretti industriali per le Osservazioni della Terra” (Development of Industrial Districts for Earth Observations) funded by MIUR (Ministero dell'Università e della Ricerca Scientifica --Italian Ministry of the University and Scientific Research) two operational mesoscale models were set-up for Calabria, the southernmost tip of the Italian peninsula. Models are RAMS (Regional Atmospheric Modeling System) and MM5 (Mesoscale Modeling 5) that are run every day at Crati scrl to produce weather forecast over Calabria (http://www.crati.it). This paper reports model intercomparison for Quantitative Precipitation Forecast evaluated for a 20 month period from 1th October 2000 to 31th May 2002. In addition to RAMS and MM5 outputs, QBOLAM rainfall fields are available for the period selected and included in the comparison. This model runs operationally at “Agenzia per la Protezione dell'Ambiente e per i Servizi Tecnici”. Forecasts are verified comparing models outputs with raingauge data recorded by the regional meteorological network, which has 75 raingauges. Large-scale forcing is the same for all models considered and differences are due to physical/numerical parameterizations and horizontal resolutions. QPFs show differences between models. Largest differences are for BIA compared to the other considered scores. Performances decrease with increasing forecast time for RAMS and MM5, whilst QBOLAM scores better for second day forecast.

The aim of this study is to predict the clinical performance and image quality of a display system for viewing dental images. At present, the use of dedicated medical displays is not uniform among dentists - many still view images on ordinary consumer displays. This work investigated whether the use of a medical display improved the perception of dental images by a clinician, compared to a consumer display. Display systems were simulated using the MEdical Virtual Imaging Chain (MEVIC). Images derived from two carefully performed studies on periodontal bone lesion detection and endodontic file length determination, were used. Three displays were selected: a medical grade one and two consumer displays (Barco MDRC-2120, Dell 1907FP and Dell 2007FPb). Some typical characteristics of the displays are evaluated by measurements and simulations like the Modulation Function (MTF), the Noise Power Spectrum (NPS), backlight stability or calibration. For the MTF, the display with the largest pixel pitch has logically the worst MTF. Moreover, the medical grade display has a slightly better MTF and the displays have similar NPS. The study shows the instability effect for the emitted intensity of the consumer displays compared to the medical grade one. Finally the study on the calibration methodology of the display shows that the signal in the dental images will be always more perceivable on the DICOM GSDF display than a gamma 2,2 display.

Theories of language production generally describe the segment as the basic unit in phonological encoding (e.g., Dell, 1988; Levelt, Roelofs, & Meyer, 1999). However, there is also evidence that such a unit might be language specific. Chen, Chen, and Dell (2002), for instance, found no effect of single segments when using a preparation paradigm. To shed more light on the functional unit of phonological encoding in Japanese, a language often described as being mora based, we report the results of 4 experiments using word reading tasks and masked priming. Experiment 1 demonstrated using Japanese kana script that primes, which overlapped in the whole mora with target words, sped up word reading latencies but not when just the onset overlapped. Experiments 2 and 3 investigated a possible role of script by using combinations of romaji (Romanized Japanese) and hiragana; again, facilitation effects were found only when the whole mora and not the onset segment overlapped. Experiment 4 distinguished mora priming from syllable priming and revealed that the mora priming effects obtained in the first 3 experiments are also obtained when a mora is part of a syllable. Again, no priming effect was found for single segments. Our findings suggest that the mora and not the segment (phoneme) is the basic functional phonological unit in Japanese language production planning.

How changes in nutrition have influenced the development of allergic diseases in childhood

PubMed Central

2012-01-01

The increasing prevalence of allergic diseases in childhood in the last decades could be linked to concomitant dietary changes, especially with the modified and lower consumption of fruit, vegetables and minerals. The consumption of these foods by pregnant women and children in the first years of life seems to be associated with a reduced risk of asthma and related symptoms. Foods that can prevent the development of wheezing through their antioxidant effects contain vitamin C and selenium; blood levels of these elements correlate negatively with the risk of wheezing. Intake of vitamin E during pregnancy also appears to be correlated with a reduced risk of wheezing for the unborn child. Similarly, low intake of zinc and carotenoids by pregnant women is associated with an increased risk of wheezing and asthma in childhood. Fiber also has anti-inflammatory properties and protective effects against allergic diseases such as atopic dermatitis and asthma. The consumption of fat influences the development of the airways. Populations in Western countries have increased their consumption of n-6 PUFAs and, in parallel, reduced n-3 PUFAs. This has led to decreased production of PGE2, which is believed to have a protective effect against inflammation of the airways. Conflicting hypotheses also concern vitamin D; both an excess and a deficiency of vitamin D, in fact, have been associated with an increased risk of asthma. Further studies on the role of these substances are necessary before any conclusions can be drawn on a clinical level. Astratto La crescente prevalenza negli ultimi decenni delle malattie allergiche in età pediatrica potrebbe essere legata a concomitanti cambiamenti nella dieta, in particolare alla minore e modificata introduzione di frutta, verdura e minerali.

Galileo, Keplero e la "nuova scienza" sul finire dellíumanesimo

Pani, Giancarlo

At the end of the 16th century, Humanism seems to be an out of place working hypothesis. Nevertheless, it was a strong presence in philology and in rhetoric, but also in the new science, particularly in Galileo and in Kepler. Both of them were mathematicians, astronomers, and Copernicans, but they also were bound by delicate religious questions. Kepler, a Protestant, was excommunicated by the Lutheran Church because of his Calvinist ideas; Galileo, a Catholic, was excommunicated by the Holy Office, since he promoted heliocentrism. Their relationship was difficult, and marked by a reciprocal lack of understanding, the history of which is studied here. Still, Galileo and Kepler were highly creative scholars, founders of astronomy, and played a leading role in scientific progress.

Each organization wasmore » supplied with a standard information package, which included construction drawings and actual material properties for most of the materials used in the model. Each organization worked independently using their own analytical methods. This report includes descriptions of the various analytical approaches and pretest predictions submitted by each organization. Significant milestones that occur with increasing pressure, such as damage to the concrete (cracking and crushing) and yielding of the steel components, and the failure pressure (capacity) and failure mechanism are described. Analytical predictions for pressure histories of strain in the liner and rebar and displacements are compared at locations where experimental results will be available after the test. Thus, these predictions can be compared to one another and to experimental results after the test.« less

Systemic tuberculosis with morphologic skin lesions that were essentially identical developed in two infants who were born of tuberculous mothers. In each patient, the infection induced erythematous papules with central crusted dells, noted four and eight weeks after birth, respectively. In each case, the diagnosis of tuberculosis was made by examination of tissue that was obtained at laparotomy. In neither patient was Mycobacterium tuberculosis found in the skin lesions. The conditions of both patients responded well to antituberculous therapy. This article reviews the possible categorization of the skin lesions in these infants.

On the analysis of an extreme Bora wind event over the northern Adriatic Sea

NASA Astrophysics Data System (ADS)

Colucci, R. R.; Pucillo, A.

2010-09-01

On 10th March 2010 a severe Bora wind event affected the Friuli Venezia Giulia region, northeastern Italy, in particular the gulf of Trieste area (northern Adriatic Sea). Such event has been driven by a widespread westward moving cold pool aloft, coming from the Western Asia, that brought an intense potential vorticity anomaly over the western Mediterranean Sea. It determined a deep cyclogenesis involving all the troposphere. The pressure gradient force in the lowest layers forced a northeastern wind to blow with noticeable strength over the gulf of Trieste area and the Karstic region. The mean ground wind velocity has reached values above 27 m/s (about 100 km/h) for several hours, and maximum gusts exceeded 42 m/s (about 150 km/h) over Trieste town. The northeastern sector of the Adriatic Sea is frequently affected by strong Bora events in particular during the winter semester. This is a characteristic local wind mostly influenced by the orography of the Karstic relieves to the east of Trieste town. The target of this work is to assess the climatological relevance of such an event by comparing it with the most representative events of the past. It has been possible thanks to the long term archive of meteorological observations in Trieste site (I.R. Accademia di Commercio e Nautica, Regio Comitato Talassografico Italiano, Ministero dell'Agricoltura e Foreste, Consiglio Nazionale delle Ricerche): we have found out that this is one of the ten strongest Bora event along the 1871-2010 period. Considerations about the trend and frequency of severe Bora events have been proposed.

Riassunto. L'analisi è stata condotta al fine di valutare l'effetto sia sulla sopravvivenza globale (OS) sia sulla sopravvivenza libera da progressione di malattia (PFS) della chemioterapia di combinazione in prima linea per il carcinoma pancreatico in fase avanzata di malattia. La presente analisi è limitata agli studi randomizzati controllati (RCT) di fase III. Successivamente è stata applicata la European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO-MCBS) agli RCT di fase III analizzati per ricavare uno score relativo all'entità del beneficio clinico ottenuto per ciascun RCT. Sono state calcolate inoltre le differenze in termini di PFS tra i diversi bracci di trattamento rapportandole con i costi dei farmaci necessari per ottenere il beneficio di PFS. La nostra analisi ha valutato 11 RCT di fase III, per un totale di 4572 pazienti. Combinando i costi della terapia con la misura dell'efficacia espressa dalla PFS, è stato ottenuto un costo di 74,12 euro (€) per mese di vita guadagnato in termini di PFS con la combinazione di 5-fluorouracil, leucovorin, irinotecan e oxaliplatino (FOLFIRINOX), 90,14 € per la combinazione di gemcitabina e oxaliplatino (GEMOX) e 4708,7 € per la combinazione di nab-paclitaxel e gemcitabina. Da questo punto di vista riteniamo che l'utilizzo delle "vecche chemioterapie di combinazione" (per es., GEMOX) non dovrebbe essere completamente abbandonato, ma valutato sul singolo paziente, sulla base di diversi fattori (età, ECOG PS, comorbilità, carico di malattia), al fine di ottenere una reale "tailored therapy".

A 55-year-old man presented with a three-week history of pruritic, erythematous papules with hyperkeratotic dells on the dorsum of the left hand, which was preceded by swelling, redness and itching. Histopathologic examination showed an acanthotic epidermis with a central invagination filled with a plug composed of parakeratotic debris, collagen, and inflammatory cells. These findings are consistent with acquired reactive perforating collagenosis, which is most frequently reported in patients with pruritus and underlying diabetes mellitus or chronic renal insufficiency. Topical and oral retinoids and topical and intralesional glucocorticoids have been reported to be effective in some patients in case series.

Capitanio, G; Stracca Pansa, V

2000-04-01

Venice had a long tradition and great reputation in the study of anatomical science dating back to the 1300's. The "Serenissima" Republic favoured the study and practice of anatomy as part of medical professional formation. Before the construction of the anatomical theater of San Giacomo dell'Orio, which took place in 1671, anatomical dissections were performed in churches, convents, hospitals and private homes. Even though Venice was not a University seat, it boosted numerous Venetian anatomists, among whom Benedetti, Massa, Santorini, and the medical activity of illustrious professors at the nearby University of Padua such as Vesalio, Falloppio, Spigelio, Vislingio and Morgagni.

Comparison study of five different display modalities for whole slide images in surgical pathology and cytopathology in Europe

User experience with viewing images in pathology is crucial for accurate interpretation and diagnosis. With digital pathology, images are being read on a display system, and this poses new types of questions: such as what is the difference in terms of pixelation, refresh lag or obscured features compared to an optical microscope. Is there a resultant change in user performance in terms of speed of slide review, perception of adequacy and quality or in diagnostic confidence? A prior psychophysical study was carried out comparing various display modalities on whole slide imaging (WSI) in pathology at the University of Pittsburgh Medical Center (UPMC) in the USA. This prior study compared professional and non-professional grade display modalities and highlighted the importance of using a medical grade display to view pathological digital images. This study was duplicated in Europe at the Department of Pathology in Erasme Hospital (Université Libre de Bruxelles (ULB)) in an attempt to corroborate these findings. Digital WSI with corresponding glass slides of 58 cases including surgical pathology and cytopathology slides of varying difficulty were employed. Similar non-professional and professional grade display modalities were compared to an optical microscope (Olympus BX51). Displays ranged from a laptop (DELL Latitude D620), to a consumer grade display (DELL E248WFPb), to two professional grade monitors (Eizo CG245W and Barco MDCC-6130). Three pathologists were selected from the Department of Pathology in Erasme Hospital (ULB) in Belgium to view and interpret the pathological images on these different displays. The results show that non-professional grade displays (laptop and consumer) have inferior user experience compared to professional grade monitors and the optical microscope.

Error biases in inner and overt speech: evidence from tongue twisters.

PubMed

Corley, Martin; Brocklehurst, Paul H; Moat, H Susannah

2011-01-01

To compare the properties of inner and overt speech, Oppenheim and Dell (2008) counted participants' self-reported speech errors when reciting tongue twisters either overtly or silently and found a bias toward substituting phonemes that resulted in words in both conditions, but a bias toward substituting similar phonemes only when speech was overt. Here, we report 3 experiments revisiting their conclusion that inner speech remains underspecified at the subphonemic level, which they simulated within an activation-feedback framework. In 2 experiments, participants recited tongue twisters that could result in the errorful substitutions of similar or dissimilar phonemes to form real words or nonwords. Both experiments included an auditory masking condition, to gauge the possible impact of loss of auditory feedback on the accuracy of self-reporting of speech errors. In Experiment 1, the stimuli were composed entirely from real words, whereas, in Experiment 2, half the tokens used were nonwords. Although masking did not have any effects, participants were more likely to report substitutions of similar phonemes in both experiments, in inner as well as overt speech. This pattern of results was confirmed in a 3rd experiment using the real-word materials from Oppenheim and Dell (in press). In addition to these findings, a lexical bias effect found in Experiments 1 and 3 disappeared in Experiment 2. Our findings support a view in which plans for inner speech are indeed specified at the feature level, even when there is no intention to articulate words overtly, and in which editing of the plan for errors is implicated.

2003-01-01

This study tested a conceptual model based on research supporting the relationship between the predictors of hardiness, supervisor support, and group cohesion and the criterions of job stress and job satisfaction and between the predictor of job stress and the criterion of job satisfaction. The study employed a cross-sectional research design. Survey data were collected as part of the baseline measures assessed prior to an organizational hardiness intervention. Worksite of Dell Computer Corporation in Austin, Texas. The subjects included 160 full-time Dell employees recruited from a convenience sample representing nine work groups (response rate = 90%). Hardiness was measured using the Dispositional Resilience Scale (DRS), job stress was measured using the Perceived Work Stress Scale (PWSS), and supervisor support, group cohesion, and job satisfaction were measured using a proprietary employee attitude survey. In the proposed model, high hardiness, supervisor support, and group cohesion were related to lower levels of job stress, which in turn was related to higher levels of job satisfaction. The model also proposed direct paths from hardiness, supervisor support, and group cohesion to job satisfaction. Path analysis was used to examine the goodness of fit of the model. The proposed model was a good fit for the data (chi 2[1, N = 160] = 1.85, p = .174) with the exception of the direct path between group cohesion and job satisfaction. Substantial portions of the variances in job stress (R2 = .19) and job satisfaction (R2 = .44) were accounted for by the predictors. Implications for targeted worksite health promotion efforts to lower job stress and enhance job satisfaction are discussed.

Obstructive Sleep Apnea Syndrome (OSAS) is a sleeping disorder caused by repeated episodes of partial or complete obstruction of the upper airways during sleep. During 2013, a pilot project was performed in the Marche region (Italy), co-jointly by the University "Politecnica delle Marche" and the Italian National Institute of Work Accident Insurance (INAIL), among holders of a category "B" driver's licence and among professionals undergoing screening at an Occupational Medicine Service covering the Province of Pesaro-Urbino (Italy). Nineteen percent of 553 subjects undergoing a screening examination were found to be affected by OSAS. The data collected is of great interest in the phase of implementation of new national laws.

The magnetic declination is the compass deviation from astronomical North. Georg Hartmann in 1510 in Rome firstly measured it as 6° East. Using accurate solar ephemerides and a UTC synchronized watch, the shadow of a vertical pole is astronomically referenced. The angles of a 10m size triangle including the direction of this shadow, the solar azimuth, and the magnetic North give the magnetic declination with an accuracy of 2 arcmin.

Atmospheric temperatures in the Alps are increasing at twice the global rate and this change may be amplified at the highest elevations. There is a scarcity of paleo-climate information from high altitudes to place this current rapid climate change in a paleo-perspective. The 'Ortles Project' is an international scientific effort gathering institutes from six nations with the primary goal of obtaining a high altitude paleo-climate record in the Mediterranean area. In 2011 four ice cores were extracted from Alto dell'Ortles (3859 m, South Tyrol, Italy) the highest glacier in the eastern Alps. This site is located ~30 km away from where the famous ~5.2 kyr old Tyrolean Ice Man was discovered emerging from an ablating ice field (Hauslabjoch, 3210 m) in 1991. The good state of conservation of this mummy suggested that the current warming trend is unprecedented in South Tyrol during the late Holocene and that unique prehistoric ice was still present in this region. During the ice core drilling operations we found that the glacier Alto dell'Ortles shows a very unusual thermic behavior as it is transitioning from a cold to a temperate state. In fact, below a 30 meter thick temperate firn portion, we observed cold ice layers sitting on a frozen bedrock (-2.8 C). These represent remnants of the colder climate before ~1980 AD, when an instrumental record indicates a ~2 C lower temperature in this area during the period 1864-1980 AD. By analyzing one of the Ortles cores for stable isotopes, dust and major ions, we found an annually preserved climatic signal embedded in the deep cold ice of this glacier. Alto dell'Ortles is therefore the first low-accumulation (850 mm w.e. per year) alpine drilling site where both winter and summer layers can be identified. Preliminary annual layer counting and two absolute time markers suggest that the time period covered by the Ortles ice cores spans from several centuries to a few millennia. In particular, a Larix (larch) leaf discovered at

A nondestructive stratigraphic and radiographic neutron study of Lorenzo Ghiberti's reliefs from paradise and north doors of Florence baptistery

A neutron study on two gilded bronze reliefs by Lorenzo Ghiberti is presented. The two reliefs, representing heads of prophets, come from the north and east doors of the Baptistery of Florence. The east door will be permanently located at the Museo dell'Opera di Santa Maria del Fiore museum at the end of its restoration, which is still in progress at the Metals Conservation Department of the Opificio delle Pietre Dure in Florence. The north door is kept in the original site, on the north facade of the Florentine Baptistery. Both reliefs exhibit critical aspects regarding their state of conservation in particular the stability of the gold layer on the bronze surface. Moreover the east head presents a remelting of which extension and composition are still unknown. The present work describes a non-destructive study of the subgilding area and bulk. The two main objectives of such analyses are: (1) to study the manufacturing technique and state of conservation of the reliefs; and (2) to assess the two cleaning techniques (laser cleaning and Rochelle salts chemical cleaning) used by the conservators during the restoration process of the east door. The experiment was carried out using prompt gamma-ray activation imaging combined with neutron radiography and conventional neutron radiography. The former method was applied to map the elemental composition of the two reliefs, while neutron radiography was used to investigate the bulk. The results provide significant information about subsuperficial areas, elemental composition of the objects from the surface down to a depth of 1 mm below gilding, and bulk structure of the remelting. Such information will guide the curators in the selection of the most suitable microclimatic conditions for the exhibition of the east door and for future conservation work on the north door.

Three-dimensional instabilities of pantographic sheets with parabolic lattices: numerical investigations

NASA Astrophysics Data System (ADS)

Scerrato, Daria; Giorgio, Ivan; Rizzi, Nicola Luigi

2016-06-01

In this paper, we determine numerically a large class of equilibrium configurations of an elastic two-dimensional continuous pantographic sheet in three-dimensional deformation consisting of two families of fibers which are parabolic prior to deformation. The fibers are assumed (1) to be continuously distributed over the sample, (2) to be endowed of bending and torsional stiffnesses, and (3) tied together at their points of intersection to avoid relative slipping by means of internal (elastic) pivots. This last condition characterizes the system as a pantographic lattice (Alibert and Della Corte in Zeitschrift für angewandte Mathematik und Physik 66(5):2855-2870, 2015; Alibert et al. in Math Mech Solids 8(1):51-73, 2003; dell'Isola et al. in Int J Non-Linear Mech 80:200-208, 2016; Int J Solids Struct 81:1-12, 2016). The model that we employ here, developed by Steigmann and dell'Isola (Acta Mech Sin 31(3):373-382, 2015) and first investigated in Giorgio et al. (Comptes rendus Mecanique 2016, doi: 10.1016/j.crme.2016.02.009), is applicable to fiber lattices in which three-dimensional bending, twisting, and stretching are significant as well as a resistance to shear distortion, i.e., to the angle change between the fibers. Some relevant numerical examples are exhibited in order to highlight the main features of the model adopted: In particular, buckling and post-buckling behaviors of pantographic parabolic lattices are investigated. The fabric of the metamaterial presented in this paper has been conceived to resist more effectively in the extensional bias tests by storing more elastic bending energy and less energy in the deformation of elastic pivots: A comparison with a fabric constituted by beams which are straight in the reference configuration shows that the proposed concept is promising.

Neural evidence for predictive coding in auditory cortex during speech production.

PubMed

Okada, Kayoko; Matchin, William; Hickok, Gregory

2018-02-01

Recent models of speech production suggest that motor commands generate forward predictions of the auditory consequences of those commands, that these forward predications can be used to monitor and correct speech output, and that this system is hierarchically organized (Hickok, Houde, & Rong, Neuron, 69(3), 407--422, 2011; Pickering & Garrod, Behavior and Brain Sciences, 36(4), 329--347, 2013). Recent psycholinguistic research has shown that internally generated speech (i.e., imagined speech) produces different types of errors than does overt speech (Oppenheim & Dell, Cognition, 106(1), 528--537, 2008; Oppenheim & Dell, Memory & Cognition, 38(8), 1147-1160, 2010). These studies suggest that articulated speech might involve predictive coding at additional levels than imagined speech. The current fMRI experiment investigates neural evidence of predictive coding in speech production. Twenty-four participants from UC Irvine were recruited for the study. Participants were scanned while they were visually presented with a sequence of words that they reproduced in sync with a visual metronome. On each trial, they were cued to either silently articulate the sequence or to imagine the sequence without overt articulation. As expected, silent articulation and imagined speech both engaged a left hemisphere network previously implicated in speech production. A contrast of silent articulation with imagined speech revealed greater activation for articulated speech in inferior frontal cortex, premotor cortex and the insula in the left hemisphere, consistent with greater articulatory load. Although both conditions were silent, this contrast also produced significantly greater activation in auditory cortex in dorsal superior temporal gyrus in both hemispheres. We suggest that these activations reflect forward predictions arising from additional levels of the perceptual/motor hierarchy that are involved in monitoring the intended speech output.

Planning for avian flu disruptions on global operations: a DMAIC case study.

Kumar, Sameer

2012-01-01

The author aims to assess the spread of avian flu, its impact on businesses operating in the USA and overseas, and the measures required for corporate preparedness. Six Sigma DMAIC process is used to analyze avian flu's impact and how an epidemic could affect large US business operations worldwide. Wal-Mart and Dell Computers were chosen as one specializes in retail and the other manufacturing. The study identifies avian flu pandemic risks including failure modes on Wal-Mart and Dell Computers global operations. It reveals the factors that reinforce avian-flu pandemic's negative impact on company global supply chains. It also uncovers factors that balance avian-flu pandemic's impact on their global supply chains. Avian flu and its irregularity affect the research outcomes because its spread could fluctuate based on so many factors that could come into play. Further, the potential cost to manufacturers and other supply chain partners is relatively unknown. As a relatively new phenomenon, quantitative data were not available to determine immediate costs. In this decade, the avian influenza H5N1 virus has killed millions of poultry in Asia, Europe and Africa. This flu strain can infect and kill humans who come into contact with this virus. An avian influenza H5N1 outbreak could lead to a devastating effect on global food supply, business services and business operations. The study provides guidance on what global business operation managers can do to prepare for such events, as well as how avian flu progression to a pandemic can disrupt such operations. This study raises awareness about avian flu's impact on businesses and humans and also highlights the need to create contingency plans for corporate preparedness to avoid incurring losses.

DUSTER: collection of meteoric CaO and carbon smoke particles in the upper stratosphere .

NASA Astrophysics Data System (ADS)

Della Corte, V.; Rietmeijer, F. J. M.; Rotundi, A.; Ferrari, M.; Palumbo, P.

Nanometer- to micrometer-size particles present in the upper stratosphere are a mixture of terrestrial and extra-terrestrial origins. They can be extraterrestrial particles condensed after meteor ablation. Meteoric dust in bolides is occasionally deposited into the lower stratosphere around 20 km altitude. Nanometer CaO and pure carbon smoke particles were collected at 38 km altitude in the upper stratosphere in the Arctic during June 2008 using DUSTER (Dust in the Upper Stratosphere Tracking Experiment and Retrieval), a balloon-borne instrument for the non-destructive collection of solid particles between 200 nm to 40 microns. We report the collection of micron sized CaCO_3 (calcite) grains. Their morphologies show evidence of melting and condensation after vaporization suggest at temperatures of approximately 3500 K. The formation environment of the collected grains was probably a dense dust cloud formed by the disintegration of a carbonaceous meteoroid during deceleration in the Earth� atmosphere. For the first time, DUSTER collected meteor ablation products that were presumably associated with the disintegration of a bolide crossing the Earth's atmosphere. The collected mostly CaO and pure carbon nanoparticles from the debris cloud of a fireball, included: 1) intact fragments; 2) quenched melted grains; and 3) vapor phase condensation products. The DUSTER project was funded by the Italian Space Agency (ASI), PRIN2008/MIUR (Ministero dell'Istruzione dell'Universitá e della Ricerca), PNRA 2013(Piano Nazionale Ricerca Antartide).

OBIETTIVI: valutare l'andamento temporale della mortalità per patologie respiratorie nelle province pugliesi utilizzando dati omogenei per fonte e metodologia di calcolo. DISEGNO: analisi ecologica storica degli andamenti temporali di mortalità per tumori e patologie dell'apparato respiratorio nelle province pugliesi, in Puglia e nelle ripartizioni geografiche italiane dal 1933 al 2010. SETTING E PARTECIPANTI: i dati di mortalità e le popolazioni residenti sono di fonte Istat. Sono state esaminate tutte le cause di decesso, il tumore della laringe, il tumore del polmone, l'insieme dei tumori respiratori, la bronchite, la polmonite e la broncopolmonite considerate congiuntamente, e l'insieme delle patologie respiratorie. Le analisi sono disaggregate per sesso dal 1969. PRINCIPALI MISURE DI OUTCOME: rapporti standardizzati di mortalità (SMR%) in riferimento all'Italia, con intervalli di confidenza al 95%, e tassi di mortalità standardizzati col metodo diretto (TSD ) in riferimento alla popolazione standard europea. RISULTATI: dal 1933 al 2010, i TSD per tumori respiratori e per bronchiti diminuiscono in tutte le aree analizzate. Tuttavia, nelle province di Taranto, Brindisi e Lecce, l'SMR% per tumori respiratori, inferiore al riferimento nazionale fino agli anni Sessanta, si allinea (a Brindisi) e supera (a Lecce e Taranto) il riferimento negli anni successivi. Nelle province di Foggia e Bari il numero dei decessi per tumore del polmone è costantemente inferiore all'atteso. CONCLUSIONI: la ricostruzione storica e l'analisi dei trend temporali di mortalità dal 1933 al 2010 mostrano alcune criticità sanitarie in periodi specifici. L'elaborazione dei dati di mortalità per un arco temporale di circa 80 anni ha messo in evidenza la maggiore rilevanza di queste criticità con l'avvio dello sviluppo industriale.

Since 1998, the Istituto Zooprofilattico Sperimentale dell'Abruzzo e Molise 'G. Caporale' in Teramo is conducting radioecological surveys in the Abruzzo region (Central Italy), to acquire knowledge on the geochemical and biological mobility of radionuclides derived from the Chernobyl accident. To this end, samples of grasses, fungi, mosses and soils were collected in four national parks (Sirente-Velino, Abruzzo Lazio and Molise, the Gran Sasso and the park of Monti della Laga and Maiella). The results show that the Chernobyl fallout is still detectable in the samples collected in the four parks but the (137)Cs concentrations are present in the semi-natural environments in quantities that do not create concerns from a radiological point of view.

KENNEDY SPACE CENTER, FLA. -- United Space Alliance technician Dell Chapman applies the Teflon-coated fabric to the gap filler before installation on the orbiter Discovery, which is being processed in Orbiter Processing Facility Bay 3 at NASA’s Kennedy Space Center. This work is being performed due to two gap fillers that were protruding from the underside of Discovery on the first Return to Flight mission, STS-114. New installation procedures have been developed to ensure the gap fillers stay in place and do not pose any hazard during the shuttle's re-entry to the atmosphere. Discovery is the scheduled orbiter for the second space shuttle mission in the return-to-flight sequence.

A study of the relationship between micropulsations and solar wind properties

NASA Technical Reports Server (NTRS)

1991-01-01

A year-long comparison between daily averages of solar wind parameters obtained from the MIT experiment on IMP-8 and micropulsation measurements made by the Universita dell'Aquila has shown a correlation between solar wind speed and micropulsation power with peaks of the correlation coefficient greater than 0.8 in the period range from 20 to 40 s. Different behavior observed for different period bands suggests that the shorter period activity tends to precede the highest values of the solar wind speed while the longer period activity tends to persist for longer intervals within high velocity solar wind streams. A comparison with simultaneous interplanetary magnetic field measurements supports the upstream origin of the observed ground pulsations.

A rapid assessment, using the abundance and distribution range method, was used to evaluate the status of a large branching bryozoan, Zoobotryon verticillatum attached to the immersed part of marina pontoons in the Canary Islands. Colonies were also found attached to the hulls of leisure craft berthed alongside pontoons at three marinas in Lanzarote during 2012. Low levels of abundance and distribution of the bryozoan occurred in marinas with a freshwater influence whereas in a sheltered marina lacking direct freshwater inputs colonies occurred at ∼2 per metre of combined pontoon length. While the occurrence of this bryozoan is recent it may be expected to occur elsewhere in Macaronesia most probably spread by leisure craft. Copyright © 2012 Elsevier Ltd. All rights reserved.

The International Classification for Nursing Practice (ICNP®) is the only nursing terminology that has been accepted within the Family of International Classification of the World Health Organization. The academic teaching of ICNP® could contribute to improve nursing clinical practice. However, standards for its implementation in undergraduate nursing education together with a nursing theoretical model are not available. To know the state of the art about the use of ICNP® in undergraduate nursing education and its use with a nursing theoretical model. A narrative literature review was conducted searching main health scientific databases and including monographs, statements from international associations, and published conference papers. Available literature about ICNP® implementation in nursing education and its use with theoretical models is limited. Results supported the organization of a specific course on ICNP® before clinical teaching programs, the development of paper or electronic ICNP® based educational tools, and the use of active learning strategies. Only three experiences reporting the use of ICNP® with theoretical models have been found. Both the use of ICNP® in nursing undergraduate education and its use according to one or more nursing theoretical models, could help students to learn nursing process. However, weak recommendations can be found in the literature to orient ICNP® implementation in undergraduate nursing education and/or with an explicit theoretical framework. Further studies focusing on these issues are strongly needed.

Planetary Nebula

This planetary nebula's simple, graceful appearance is thought to be due to perspective: our view from Earth looking straight into what is actually a barrel-shaped cloud of gas shrugged off by a dying central star. Hot blue gas near the energizing central star gives way to progressively cooler green and yellow gas at greater distances with the coolest red gas along the outer boundary. Credit: NASA/Hubble Heritage Team ---- The Ring Nebula's distinctive shape makes it a popular illustration for astronomy books. But new observations by NASA's Hubble Space Telescope of the glowing gas shroud around an old, dying, sun-like star reveal a new twist. "The nebula is not like a bagel, but rather, it's like a jelly doughnut, because it's filled with material in the middle," said C. Robert O'Dell of Vanderbilt University in Nashville, Tenn. He leads a research team that used Hubble and several ground-based telescopes to obtain the best view yet of the iconic nebula. The images show a more complex structure than astronomers once thought and have allowed them to construct the most precise 3-D model of the nebula. "With Hubble's detail, we see a completely different shape than what's been thought about historically for this classic nebula," O'Dell said. "The new Hubble observations show the nebula in much clearer detail, and we see things are not as simple as we previously thought." The Ring Nebula is about 2,000 light-years from Earth and measures roughly 1 light-year across. Located in the constellation Lyra, the nebula is a popular target for amateur astronomers.

Zones of precariously balanced rocks have been used as negative indicators of previous strong ground motion in seismically active regions of Southern California and Nevada (e.g. Brune 1996). Understanding the geologic context and the geomorphic framework that control the formation and preservation of precarious rocks is essential to testing their fidelity for extreme ground motion analyses. In this study we assess the geologic settings and the geomorphic processes nested within them using precarious rock zones (Granite Dells, Texas Canyon, and Granite Pediment) in low-seismicity regions of Arizona and Southern California. The Granite Dells locality is a ~20 km2 Proterozoic granite field that is ~5 km from the Prescott Valley graben faults (<0.2 mm/yr of Quaternary slip). The Texas Canyon locality is a ~132 km2 Mesozoic granite field that is ~23 km from the Little Rincon Mountains fault (<0.2 mm/yr of Quaternary slip). The Granite Pediment locality is a ~12 km2 Mesozoic granite pediment located ~96 km from the eastern section of the Garlock fault (<5 mm/yr of Quaternary slip). Characterization of the geologic context of each site included assembling a digital geologic database for Arizona, Southern California, and southern Nevada. The geologic database was queried for granitic bodies and Quaternary deposits. Active faults were categorized by their Quaternary slip rates, and a 20 km zone of no precarious rocks was created around each active fault based on the field surveys of Brune (1996). Aerial photographs were used to map the spatial distribution and geometry of joint sets within each site. Ground surveys using hand-held GPS units and digital photography were conducted to document the characteristics (lithology, size, fragility, weathering characteristics) and spatial density of precariously balanced rocks. Morphometric analyses of digital elevation data may indicate if there is a slope or relief range which the precarious rocks are optimally produced and

OBIETTIVI: descrivere, nella ASL 21 di Legnago (VR), l'andamento di alcuni indicatori sanitari tra il 2009, anno precedente all'avvio di un progetto triennale per la gestione integrata dell'assistenza al paziente con diabete mellito di tipo 2, e il 2012, ultimo anno del progetto. DISEGNO: studio longitudinale trasversale ripetuto. SETTING E PARTECIPANTI: tutti i pazienti diabetici di tipo 2 della ASL 21, identificati nei database aziendali (in base a esenzioni per patologia, accessi al servizio diabetologico, consumo di farmaci antidiabetici e strisce per la determinazione della glicemia) e nelle cartelle cliniche dei medici di famiglia. PRINCIPALI MISURE DI OUTCOME: numero di test diagnostici e di follow-up erogati, consumo di farmaci, prestazioni specialistiche, accessi al pronto soccorso, ricoveri e mortalità. RISULTATI: nonostante un calo generalizzato (-3,1%) nei test erogati dalla ASL 21 ai suoi assistititi nel periodo 2009-2012, l'analisi ha documentato un marcato aumento per gli esami previsti nella gestione del diabete, quali curve da carico glicemico (+104,3%), emoglobina glicata (+19,0%) e microalbuminuria (+296,1%). I soggetti identificati come diabetici sono aumentati da 8.084 nel 2009 (5,2%) a 9.221 nel 2012 (5,9%). Sono stati osservati aumenti nella prevalenza di pazienti visitati presso un servizio diabetologico (dal 22,6% al 39,0%), nonché negli utilizzatori di metformina (dal 28,0% al 37,5%), insuline (dal 13,5% al 18,3%) e incretine (dall'1,4% al 9,0%). Il consumo di sulfaniluree è, invece, calato (dal 49,9% al 40,8%), come anche l'erogazione di alcune prestazioni specialistiche, gli accessi al pronto soccorso e i ricoveri, mentre il tasso di mortalità è rimasto stabile (29,6 decessi x1.000/anno). CONCLUSIONE: durante il periodo di implementazione del progetto sembra essersi verificato un aumento della sensibilità diagnostica e una maggiore presa in carico del paziente diabetico.

An overview of statistical tests of peaks and periodicities in the redshift distribution of quasi-stellar objects is presented. The tests include the power-spectrum analysis carried out by Burbidge and O'Dell (1972), the generalized Rayleigh test, the Kolmogorov-Smirnov test, and the 'comb-tooth' test. The tests reveal moderate to strong evidence for periodicities of 0.0565 and 0.0127-0.0129. The confidence level of the periodicity of 0.0565 in fact marginally increases when redshifts are transformed to the Galactocentric frame. The same periodicity, first noticed in 1968, persists to date with a QSO population that has since grown about 30 times its original size. The prima facie evidence for periodicities in 1n(1 + z) is found to be of no great significance.

A GIANT STAR FACTORY IN NEIGHBORING GALAXY NGC 6822

NASA Technical Reports Server (NTRS)

2002-01-01

Resembling curling flames from a campfire, this magnificent nebula in a neighboring galaxy is giving astronomers new insight into the fierce birth of stars as it may have more commonly happened in the early universe. The glowing gas cloud, called Hubble-V, has a diameter of about 200 light-years. A faint tail of nebulosity trailing off the top of the image sits opposite a dense cluster of bright stars at the bottom of the irregularly shaped nebula. NASA's Hubble Space Telescope's resolution and ultraviolet sensitivity reveals a dense knot of dozens of ultra-hot stars nestled in the nebula, each glowing 100,000 times brighter than our Sun. These youthful 4-million-year-old stars are too distant and crowded together to be resolved from ground-based telescopes. The small, irregular host galaxy, called NGC 6822, is one of the Milky Way's closest neighbors and is considered prototypical of the earliest fragmentary galaxies that inhabited the young universe. The galaxy is 1.6 million light-years away in the constellation Sagittarius. The Hubble-V image data was taken with Hubble's Wide Field Planetary Camera 2 (WFPC2) by two science teams: C. Robert O'Dell of Vanderbilt University and collaborators, and Luciana Bianchi of Johns Hopkins University and Osservatorio Astronomico, Torinese, Italy, and collaborators. This color image was produced by The Hubble Heritage Team (STScI). A Hubble image of Hubble-X, another intense star-forming region in NGC 6822, was released by The Heritage Team in January 2001.

Hardware and software specialized for real time control reduce the timing jitter of executables when compared to off-the-shelf hardware and software. However, these specialized environments are costly in both money and development time. While conventional systems have a cost advantage, the jitter in these systems is much larger and potentially problematic. This study analyzes the timing characterstics of a standard Dell server running a fully featured Linux operating system to determine if such a system would be capable of meeting the timing requirements for closed loop operations. Investigations are preformed on the effectiveness of tools designed to make off-the-shelf system performance closer to specialized real time systems. The Gnu Compiler Collection (gcc) is compared to the Intel C Compiler (icc), compiler optimizations are investigated, and real-time extensions to Linux are evaluated.

Nel corso dell’ultimo decennio l’esplorazione planetaria ha potuto beneficiare dei dati prodotti dagli spettrometri ad immagine: grazie a questa nuova classe di strumenti, realizzati per l’osservazione in remoto di superfici ed atmosfere planetarie, è possibile acquisire dati iperspettrali con elevati poteri risolutivi spaziali e spettrali. Il principale vantaggio offerto dagli spettrometri ad immagine, rispetto alle camere ed agli spettrometri puntuali, è rappresentato dalla capacità di misurare, identificare e mappare le unità composizionali delle superfici planetarie; queste informazioni permettono di investigare sia l’evoluzione geochimica delle superfici sia la dinamica e la composizione delle atmosfere. Sebbene i primi spettrometri ad immagine siano stati francesi (Phobos/ISM, Imaging Spectrometer for Mars) e statunitensi (Galileo/NIMS, Near Infrared Mapping Spectrometer), il nostro paese nel corso degli ultimi anni è stato in grado di proporre alla com unità spaziale internazionale degli strumenti dalle elevate prestazioni che sono stati infatti accettati come payload scientifici su diverse missioni interplanetarie: dai canali visibili di VIMS (Visual and Infrared Mapping Spectrometer) su Cassini (Nasa, JPL, ESA, ASI) e di OMEGA (Observatoire pour la Minéralogie, l’Eau, les Glacies et l’Activitè de Mars) su MarsExpress (ESA) ai due VIRTIS (Visible and Infrared Thermal Imaging Spectrometer) su Rosetta (ESA) e VenusExpress (ESA) fino a VIR-MS (Visible and Infrared Mapping Spectrometer) su Dawn (Nasa).

for the White Rim oil. The most attractive potential sources for White Rim oil include beds within one or more of the following formations: the Proterozoic Chuar Group, which is present in the subsurface southwest of the Tar Sand triangle; the Mississippian Delle Phosphatic Member of the Deseret Limestone and equivalent formations, the Permian Kaibab Limestone, the Sinbad Limestone Member of the Triassic Moenkopi Formation, and the Jurassic Arapien Shale, Twin Creek Limestone, and Carmel Formation, which are present west of the Tar Sand triangle; the Pennsylvanian Paradox Formation in the Paradox basin east of the Tar Sand triangle; and the Permian Park City Formation northwest of the Tar Sand triangle. Each formation has a high total organic carbon content and is distributed over a wide enough geographic area to have provided a huge volume of oil. Source beds in all of the formations reached thermal maturity at times prior to or during the time that migration into the White Rim is interpreted to have occurred. Based on all available data, the most likely source for the Tar Sand triangle appears to be the Mississippian Delle Phosphatic Member of the Deseret Limestone. Secondary migration out of the Delle is interpreted to have occurred during the Cretaceous, during Sevier thrusting. Subsequent tertiary migration into the Tar Sand triangle reservoir is interpreted to have occurred later, during middle Tertiary Laramide deformation.

We tried to adopt the fundaments of the seascape concept, based on the thematic elements of landscape ecology and translated into terms fitting with the principles of coastal ecology. The seascape concept is central to our view of the environment and is referred to as an integrated unit (Environmental Unit) resulting from a long multidisciplinary approach, carried out in both the field and the laboratory by an interdisciplinary team of experts. Side Scan Sonar and Multi Beam acoustical data collected in the Marettimo and Ustica Islands (south-western Tyrrhenian Sea))inner shelves, make possible to sketch geomorphological and sedimentological maps, whose details have been tested as deep as 45 m in diving surveys. On the basis of the collected data sets, the inner shelf (0-60 m) has been subdivided into different portions, following the concept of the Environmental Unit (E.U). Every E.U. presents constant morphological and sedimentological features that, probably, can be associated to specified biological communities. In order to find the relationships between physical settings and communities, geological thematic maps are eventually overlaid and fitted to macrobenthic and fishery spatial distribution maps.

The field of pituitary surgery was born in the first decade of the twentieth century in Europe, and it evolved rapidly with the development of numerous innovative surgical techniques by some of the founding fathers of neurosurgery. This study investigates the pioneering Italian treatise on pituitary surgery, La Patologia Chirurgica dell'Ipofisi (Surgical Pathology of the Hypophysis), published in 1911 by Giovanni Verga (1879-1923), a surgeon from Pavía and one of Golgi's disciples. This little-known monograph compiles the earliest experience on pituitary surgery through the analysis of the first 50 procedures performed between 1903 and 1911. We conducted a biographical survey of Giovanni Verga and the motivations for his work on pituitary surgery. In addition, a systematic analysis of all original reports and historical documents about these pituitary procedures referenced in Verga's treatise was carried out. Verga's treatise provides a summary of the techniques employed and surgical outcomes for the first 50 attempted procedures of pituitary tumor removal. This monograph is the only scientific source that includes a complete account of the series of 10 pituitary tumors operated on by Sir Victor Horsley in the 1900s. Three major types of surgery were employed: (i) palliative procedures of craniectomy (n = 6); (ii) transcranial approaches to the pituitary gland, either subfrontal or subtemporal (n = 13); and (iii) transphenoidal routes to expose the sella turcica, either using an upper transnasal-transethmoidal approach (n = 19) or a lower sublabial/endonasal-transeptal one (n = 12). An operative mortality rate of 36% (n = 17) was observed in these early series. The pathological nature of the tumors operated on was available in 42 cases. There were 28 adenomas and 15 craniopharyngiomas. Sir Victor Horsley (1857-1916) and the Viennese surgeons Anton von Eiselsberg (1860-1939) and Oskar Hirsch (1877-1965) were the leading European figures in the development

An initial comparative map of copy number variations in the goat (Capra hircus) genome

PubMed Central

2010-01-01

Background The goat (Capra hircus) represents one of the most important farm animal species. It is reared in all continents with an estimated world population of about 800 million of animals. Despite its importance, studies on the goat genome are still in their infancy compared to those in other farm animal species. Comparative mapping between cattle and goat showed only a few rearrangements in agreement with the similarity of chromosome banding. We carried out a cross species cattle-goat array comparative genome hybridization (aCGH) experiment in order to identify copy number variations (CNVs) in the goat genome analysing animals of different breeds (Saanen, Camosciata delle Alpi, Girgentana, and Murciano-Granadina) using a tiling oligonucleotide array with ~385,000 probes designed on the bovine genome. Results We identified a total of 161 CNVs (an average of 17.9 CNVs per goat), with the largest number in the Saanen breed and the lowest in the Camosciata delle Alpi goat. By aggregating overlapping CNVs identified in different animals we determined CNV regions (CNVRs): on the whole, we identified 127 CNVRs covering about 11.47 Mb of the virtual goat genome referred to the bovine genome (0.435% of the latter genome). These 127 CNVRs included 86 loss and 41 gain and ranged from about 24 kb to about 1.07 Mb with a mean and median equal to 90,292 bp and 49,530 bp, respectively. To evaluate whether the identified goat CNVRs overlap with those reported in the cattle genome, we compared our results with those obtained in four independent cattle experiments. Overlapping between goat and cattle CNVRs was highly significant (P < 0.0001) suggesting that several chromosome regions might contain recurrent interspecies CNVRs. Genes with environmental functions were over-represented in goat CNVRs as reported in other mammals. Conclusions We describe a first map of goat CNVRs. This provides information on a comparative basis with the cattle genome by identifying putative

2012-01-01

Giovanni Jervis is mainly known as a psychiatrist, but he also worked on psychological methodology and tackled important issues in clinical psychology. This essay describes the concept of personal identity elaborated by Jervis and its importance in Child Clinical Psychology. The problems related to personal identity appear very early in Jervis' work, influenced by the ethnologist Ernesto De Martino. His first considerations are found in his Preface to The Adventures of Pinocchio by Carlo Collodi (1968), in which Jervis describes the unhappy upbringing, the anti-social behaviour, and the unattained identity of the wooden puppet. Subsequently, in Presenza e identith (1984), Fondamenti di Psicologia Dinamica (1993) and La conquista dell'identith (1997), Jervis dealt with the theme of identity from a Dynamic Psychology perspective, showing that the formation of personal identity is a basic aspect of the development of the individual that starts in early childhood.

A 52 year old man, living in the province of Trapani (Sicily), presented with right hydrocele and slight orchialgia. The patient underwent epididymectomy and resection of T. vaginalis. The "tunica" was involved by a granulomatous process, containing a parasite of genus Dirofilaria (D. repens). Dirofilaria repens is a filarial nematode. Dogs, foxes and cats are the definitive hosts and principal reservoirs of the parasite. In humans the parasite dies before reaching sexual maturity and the result is an inconspicuous granulomatous reaction in the subcutaneous tissue. S. Pampiglione et al. (Cattedra di Parassitologia Veterinaria dell'Università di Bologna-Italy) reported from 1971 more than 30 cases of human Dirofilariasis in Italy, suggesting that the parasite is able to migrate from the inoculation site to other districts (lung, eye etc.). The case is exceptional for the localization of the parasite (never reported) and can contribute to a better knowledge of the disease.

Most visitors to Florence, Italy, know about the Galleria dell'Accademia, housing Michelangelo's famous statue of David, or the Galleria degli Uffizi with the famous Medici collection. Few visitors know that only two blocks from the Uffizi on the Arno River is one of the world's finest museums featuring historic scientific instruments, the Museo di Storia della Scienza. In the February issue of TPT, Nickell states that the Museo di Storia della Scienza ``is perhaps the best museum on the history of science in the world.''1 This fact is likely true, and the museum is a must for physics teachers visiting Florence. It features a vast collection of authentic ``cutting-edge'' scientific instruments, including one of Galileo's lenses in a magnificent ebony and ivory frame. One of the tragedies is that this museum goes unmarked on many tourist maps and unmentioned in many guidebooks.

What have we been priming all these years? On the development, mechanisms, and ecology of nonconscious social behavior

PubMed Central

BARGH, JOHN A.

2009-01-01

Priming or nonconscious activation of social knowledge structures has produced a plethora of rather amazing findings over the past 25 years: priming a single social concept such as aggressive can have multiple effects across a wide array of psychological systems, such as perception, motivation, behavior, and evaluation. But we may have reached childhood’s end, so to speak, and need now to move on to research questions such as how these multiple effects of single primes occur (the generation problem); next, how these multiple simultaneous priming influences in the environment get distilled into nonconscious social action that has to happen serially, in real time (the reduction problem). It is suggested that models of complex conceptual structures (Lakoff & Johnson, 1980), language use in real-life conversational settings (Clark, 1996), and speech production (Dell, 1986) might hold the key for solving these two important ‘second-generation’ research problems.

Adding similar features and bug fixes often requires porting program patches from reference implementations and adapting them to target implementations. Porting errors may result from faulty adaptations or inconsistent updates. This paper investigates (I) the types of porting errors found in practice, and (2) how to detect and characterize potential porting errors. Analyzing version histories, we define five categories of porting errors, including incorrect control- and data-flow, code redundancy, inconsistent identifier renamings, etc. Leveraging this categorization, we design a static control- and data-dependence analysis technique, SPA, to detect and characterize porting inconsistencies. Our evaluation on code from four open-source projects shows thai SPA can dell-oct porting inconsistencies with 65% to 73% precision and 90% recall, and identify inconsistency types with 58% to 63% precision and 92% to 100% recall. In a comparison with two existing error detection tools, SPA improves precision by 14 to 17 percentage points

Parametrizing the Reionization History with the Redshift Midpoint, Duration, and Asymmetry

2018-05-01

A new parametrization of the reionization history is presented to facilitate robust comparisons between different observations and with theory. The evolution of the ionization fraction with redshift can be effectively captured by specifying the midpoint, duration, and asymmetry parameters. Lagrange interpolating functions are then used to construct analytical curves that exactly fit corresponding ionization points. The shape parametrizations are excellent matches to theoretical results from radiation-hydrodynamic simulations. The comparative differences for reionization observables are: ionization fraction | {{Δ }}{x}{{i}}| ≲ 0.03, 21 cm brightness temperature | {{Δ }}{T}{{b}}| ≲ 0.7 {mK}, Thomson optical depth | {{Δ }}τ | ≲ 0.001, and patchy kinetic Sunyaev–Zel’dovich angular power | {{Δ }}{D}{\\ell }| ≲ 0.1 μ {{{K}}}2. This accurate and flexible approach will allow parameter-space studies and self-consistent constraints on the reionization history from 21 cm, cosmic microwave background (CMB), and high-redshift galaxies and quasars.

The program design included chemical analyses of water samples collected at 56 sites on the Bear, Clearwater, Kootenai, Pend Oreille, Salmon, Snake, and Spokane Rivers and their tributaries (fig. 1). Samples were collected every year (1990 through 1995) at 5 sites (annual sites), every other year at 19 sites (biennial sites), and every third year at 32 sites (triennial sites). Each year, 25 of the 56 sites were sampled. During water years 1990–95 (October 1, 1989, to September 30, 1995), samples were collected bimonthly. Onsite analyses consisted of discharge, specific conductance, pH, temperature, dissolved oxygen, bacteria (fecal coliform and fecal streptococci), and alkalinity. Laboratory analyses consisted of major ions, nutrients, trace elements, turbidity, and suspended sediment. Analytical results from the five annual sites sampled during water years 1990–93 are presented in a report by O’Dell and Berenbrock (1994).

The foundation of C. N. R. in 1923 created in Italy a new public system of research, different from the university one. During fascism, the contribution of C. N. R. to the development of medical research in Italy was very poor. This was mainly due to insufficient means: structures and money. Moreover, the scientists who carried on medical research within the C. N. R. were the same who already held strong university positions, which mean a complete dependence on the academic system. The ideology of fascism also contribute to the weakness of the Italian medical research promoted by the C. N. R.. According to fascist view, science, and for its nature and aims above all medicine, had to addressed to technical, practical, or much better, social achievements. Consequently, the policy of medical research at the C.N.R. was to improve social or political medicine, mainly hygiene. This was in harmony with the demographic policy, which means the policy of reinforcement of "Italian race", and positive eugenics that fascism tried to pursue.

Kenneth E. Little Elementary is a public school grades Pre-K to 5th in Bacliff, Texas. It has an ethnically diverse population of one-thousand boys and girls. It is a Title 1 school with eighty-six percent of the students receiving free or reduced meals. K.E. Little has a large at-risk population with a thirty-three percent transition rate. The Young Astronauts @ K.E. Little is an on-going afterschool space science program in it's third year of operation. Thirty students,fourth and fifth grade, were involved in our spring robotics program. Each co-operative group was assigned a LEGO robotics kit to inventory,organize, and familiarize themselves with. Each team made decisions, by consensus, concerning the robots design and capabilities. Students used the Dell Computer Lab on campus to program their robots. Although time did not permit the construction of a simulated Martian landscape, future Young Astronauts will continue this project in January 2004.

Climate-driven environmental changes around 8,200 years ago favoured increases in cetacean strandings and Mediterranean hunter-gatherers exploited them.

Cetacean mass strandings occur regularly worldwide, yet the compounded effects of natural and anthropogenic factors often complicate our understanding of these phenomena. Evidence of past stranding episodes may, thus, be essential to establish the potential influence of climate change. Investigations on bones from the site of Grotta dell'Uzzo in North West Sicily (Italy) show that the rapid climate change around 8,200 years ago coincided with increased strandings in the Mediterranean Sea. Stable isotope analyses on collagen from a large sample of remains recovered at this cave indicate that Mesolithic hunter-gatherers relied little on marine resources. A human and a red fox dating to the 8.2-kyr-BP climatic event, however, acquired at least one third of their protein from cetaceans. Numerous carcasses should have been available annually, for at least a decade, to obtain these proportions of meat. Our findings imply that climate-driven environmental changes, caused by global warming, may represent a serious threat to cetaceans in the near future.

Genetics of SCID

PubMed Central

2010-01-01

Human SCID (Severe Combined Immunodeficiency) is a prenatal disorder of T lymphocyte development, that depends on the expression of numerous genes. The knowledge of the genetic basis of SCID is essential for diagnosis (e.g., clinical phenotype, lymphocyte profile) and treatment (e.g., use and type of pre-hematopoietic stem cell transplant conditioning). Over the last years novel genetic defects causing SCID have been discovered, and the molecular and immunological mechanisms of SCID have been better characterized. Distinct forms of SCID show both common and peculiar (e.g., absence or presence of nonimmunological features) aspects, and they are currently classified into six groups according to prevalent pathophysiological mechanisms: impaired cytokine-mediated signaling; pre-T cell receptor defects; increased lymphocyte apoptosis; defects in thymus embryogenesis; impaired calcium flux; other mechanisms. This review is the updated, extended and largely modified translation of the article "Cossu F: Le basi genetiche delle SCID", originally published in Italian language in the journal "Prospettive in Pediatria" 2009, 156:228-238.

2008-05-01

Groundwater sensitivity (Ray and O’dell in Environ Geol 22:345 352, 1993a) refers to the inherent ease with which groundwater can be contaminated based on hydrogeologic characteristics. We have developed digital methods for identifying areas of varying groundwater sensitivity for a ten county area of south central Kentucky at a scale of 1:100,000. The study area includes extensive limestone karst sinkhole plains, with groundwater extremely sensitive to contamination. Digitally vectorized geologic quadrangles (DVGQs) were combined with elevation data to identify both hydrogeologic groundwater sensitivity regions and zones of “high risk runoff” where contaminants could be transported in runoff from less sensitive to higher sensitivity (particularly karst) areas. While future work will fine-tune these maps with additional layers of data (soils for example) as digital data have become available, using DVGQs allows a relatively rapid assessment of groundwater sensitivity for Kentucky at a more useful scale than previously available assessment methods, such as DRASTIC and DIVERSITY.

Teen dating abuse, also known as teen dating violence, is a significant public health issue. Adolescents with a history of dating abuse may struggle academically and experience increased risk for serious injury or even death. They may engage in risky sexual behavior, substance abuse, and unhealthy dieting and exhibit suicidal behaviors. School nurses may be the first adults that teens confide in when experiencing dating abuse and may lack the knowledge and skills to intervene with teens involved in unhealthy dating relationships. Beginning in 2008, Dell Children s Medical Center in Austin, Texas, partnered with SafePlace (a local nonprofit that serves survivors of sexual and domestic violence) to address dating abuse. This collaboration is part of Start Strong Austin, one of 11 communities nationwide participating in the Start Strong: Building Healthy Teen Relationships Initiative funded by the Robert Wood Johnson Foundation. The Start Strong model employs innovative strategies in education, community engagement, policy change, and social marketing to prevent dating abuse before it starts.

We have studied the femtosecond dynamics following optical laser excitation of CO adsorbed on a Ru surface by monitoring changes in the occupied and unoccupied electronic structure using ultrafast soft x-ray absorption and emission. We recently reported [M. Dell'Angela et al. Science 339, 1302 (2013)] a phonon-mediated transition into a weakly adsorbed precursor state occurring on a time scale of >2 ps prior to desorption. Here we focus on processes within the first picosecond after laser excitation and show that the metal-adsorbate coordination is initially increased due to hot-electron-driven vibrational excitations. This process is faster than, but occurs in parallel with, the transition into the precursor state. With resonant x-ray emission spectroscopy, we probe each of these states selectively and determine the respective transient populations depending on optical laser fluence. Ab initio molecular dynamics simulations of CO adsorbed on Ru(0001) were performed at 1500 and 3000 K providing insight into the desorption process.

E’ormai noto che esiste la possibilità rivoluzionaria di utilizzare il fegato per il trattamento della stadio terminale delle epatopatie. Nel gennaio 1980 si celebra il decimo anna di sopravvivenza con fegato trapiantato (la più lunga della letteratura) di un paziente da noi trattato. Si tratta di uno dei 12 malati sottoposti a trapianto e seguiti per più di 5 anni. La nota positiva di questa tipo di trattamento è rappresentata dall’eccellente tenore di vita che i pazienti conducono e dalla riabilitazione sociale e professionale. La nota negativa è data, invece, dal fatto che i buoni risultati non vengono raggiunti con regolarità e non possono essere previsti con esattezza. In questa breve rassegna considereremo la esperienza da noi fatta presso l’Università di Denver nel Colorado, mettendo in risalto le cause dell’elevata mortalità precoce e le prospettive future di questa mezzo terapeutico.

A Case-Series Test of the Interactive Two-step Model of Lexical Access: Predicting Word Repetition from Picture Naming

PubMed Central

Dell, Gary S.; Martin, Nadine; Schwartz, Myrna F.

2010-01-01

Lexical access in language production, and particularly pathologies of lexical access, are often investigated by examining errors in picture naming and word repetition. In this article, we test a computational approach to lexical access, the two-step interactive model, by examining whether the model can quantitatively predict the repetition-error patterns of 65 aphasic subjects from their naming errors. The model’s characterizations of the subjects’ naming errors were taken from the companion paper to this one (Schwartz, Dell, N. Martin, Gahl & Sobel, 2006), and their repetition was predicted from the model on the assumption that naming involves two error prone steps, word and phonological retrieval, whereas repetition only creates errors in the second of these steps. A version of the model in which lexical-semantic and lexical-phonological connections could be independently lesioned was generally successful in predicting repetition for the aphasics. An analysis of the few cases in which model predictions were inaccurate revealed the role of input phonology in the repetition task. PMID:21085621

Soil stores organic carbon more often than we can find in living vegetation and atmosphere together. This reservoir is not inert, but it is constantly in a dynamic phase of inputs and losses. Soil organic carbon mainly depends on land cover, environment conditions and soil properties. After soil deposition, the organic residues of different origin and nature, the Soil Organic Matter (SOM) can be seen involved in two different processes during the pedogenesis: mineralization and humification. The transport process along profile happens under certain conditions such as deposition of high organic residues amount on the top soil, high porosity of the soil caused by sand or skeleton particles, that determine a water strong infiltrating capacity, also, extreme temperatures can slow or stop the mineralization and/or humification process in one intermediate step of the degradation process releasing organic metabolites with high or medium solubility and high loads of water percolating in relation to intense rainfall. The transport process along soil profile can take many forms that can end in the formation of Bh horizons (h means accumulation of SOM in depth). The forest cover nature influence to the quantity and quality of the organic materials deposited with marked differences between coniferous and deciduous especially in relation to resistance to degradation. Two soils in the Campania region, located in Lago Laceno (Avellino - Italy) with different forest cover (Pinus sp. and Fagus sp.) and that meets the requirements of the place and pedological formation suitable for the formation and accumulation of SOM in depth (Bh horizon) were studied. The different soil C fractions were determinated and were assessed (Ciavatta C. et al. 1990; Dell'Abate M.T. et al. 2002) for each soil profile the Total Extractable Lipids (TEL). Furthermore, the lignin were considered as a major component of soil organic matter (SOM), influencing its pool-size and its turnover, due to the high

Damage and Site Effects of the May 2012 Emilia-Romagna and Lombardia Earthquake, with Particular Reference to the "Oltrepò Mantovano" (Mantua) Territory

2014-12-01

The seismic sequence that struck the Lombardia and Emilia-Romagna in May 2012 consisted of seven main events of magnitude greater than 5 followed by numerous aftershocks. The strongest earthquakes occurred on May 20 (M=5.9) and May 29 (M=5.8) near the border between Lombardia and Emilia-Romagna. The epicenters of the main events are aligned in east-west direction in a segment of approx. 50 km just south of the Po river. The area was considered a low to medium seismicity: the seismic hazard in the epicentral area, and in the whole damaged area, was estimated to be less than 0.15 g PGA for 10% exceedance in 50 years. Significant damage occurred over an area greater than 1000 km2, which is extremely large for earthquakes of magnitude less than 6, bearing in mind the low vulnerability level of the structures. As seen in detailed geological investigations the degree of damage and its areal extent is largely attributable to the particular conditions of the soil. We focus on the relationship between damage and soil conditions in the area of Oltrepò Mantovano, situated between the Po River and the epicentral area. The soil is largely composed of Quaternary deposits of sands, silty-clay and clay with a very deep bedrock (greater than 100 m) and Vs30 generally less than 500 m/s. According to the cards Aedes (official forms of the Italian Government to assess the state of damage of buildings) houses declared uninhabitable because of the earthquake were mainly concentrated in a few small towns: Moglia, Gonzaga, Quistello and San Giacomo delle Segnate (located approximately at 20 km, 27 km, 20 km and 14 km from the epicenters of the two main shocks, respectively) which reported 73% of the total of all uninhabitable buildings; Moglia 27 %, Gonzaga 14%, Quistello 20% and San Giacomo delle Segnate 12%. The hydrographic system has evolved considerably since the Middle Bronze Age with the result that the area is characterized by a complex geomorphology with the presence of fluvial

Assessing Glacier Hazards At Ghiacciaio Del Belvedere, Macugnaga, Italian Alps

NASA Astrophysics Data System (ADS)

Haeberli, W.; Chiarle, M.; Mortara, G.; Mazza, A.

The uppermost section of the Valle Anzasca behind and above the community of Macugnaga in the Italian Alps is one of the most spectacular high-mountain land- scapes in Europe, with gigantic rock walls and numerous steep hanging glaciers. Its main glacier, Ghiacciaio del Belvedere at the foot of the huge Monte Rosa east face, is a heavily debris-covered glacier flowing on a thick sediment bed. Problems with floods, avalanches and debris flows from this ice body have been known for extended time periods. Most recently, however, the evolution of this highly dynamic environ- ment has become more dramatic. An outburst of Lago delle Locce, an ice-dammed lake at the confluenec of the tributary Ghiacciaio delle Locce with Ghiacciaio del Belvedere, caused heavy damage in 1979 and necessitated site investigation and con- struction work to be done for flood protection. The intermittent glacier growth ten- dency in the 1970es induced strong bulging of the glacier surface and, in places, caused the glacier tongue to override historical morains and to destroy newly-grown forest stands. A surge-type flow acceleration started in the lower parts of the Monte- Rosa east face during summer 2000, leading to strong crevassing and deformation of Ghiacciaio del Belvedere and extreme bulging of its orographic right margin. High water pressure and accelerated movement lasted into winter 2001/2002: the ice now started overriding the LIA moraine near Rifugio Zamboni of the CAI. In addition but rather independently, a most active detachment zone for rock falls and debris flows developed for several years now in the east face of Monte Rosa, somewhat more to the south of the accelerated glacier movement and at an altitude where relatively warm permafrost must be expected. Besides the scientific interest in these phenomena, the growing hazard potential to the local infrastructure must be considered seriously.

Tertiary volcanic rocks and uranium in the Thomas Range and northern Drum Mountains, Juab County, Utah

Lindsey, David A.

1982-01-01

The Thomas Range and northern Drum Mountains have a history of volcanism, faulting, and mineralization that began about 42 m.y. (million years) ago. Volcanic activity and mineralization in the area can be divided into three stages according to the time-related occurrence of rock types, trace-element associations, and chemical composition of mineral deposits. Compositions of volcanic rocks changed abruptly from rhyodacite-quartz latite (42-39 m.y. ago) to rhyolite (38-32 m.y. ago) to alkali rhyolite (21 and 6-7 m.y. ago); these stages correspond to periods of chalcophile and siderophile metal mineralization, no mineralization(?), and lithophile metal mineralization, respectively. Angular unconformities record episodes of cauldron collapse and block faulting between the stages of volcanic activity and mineralization. The youngest angular unconformity formed between 21 and 7 m.y. ago during basin-and-range faulting. Early rhyodacite-quartz latite volcanism from composite volcanoes and fissures produced flows, breccias, and ash-flow tuff of the Drum Mountains Rhyodacite and Mt. Laird Tuff. Eruption of the Mt. Laird Tuff about 39 m.y. ago from an area north of Joy townsite was accompanied by collapse of the Thomas caldera. Part of the roof of the magma chamber did not collapse, or the magma was resurgent, as is indicated by porphyry dikes and plugs in the Drum Mountains. Chalcophile and siderophile metal mineralization, resulting in deposits of copper, gold, and manganese, accompanied early volcanism. Te middle stage of volcanic activity was characterized by explosive eruption of rhyolitic ash-flow tuffs and collapse of the Dugway Valley cauldron. Eruption of the Joy Tuff 38 m.y. ago was accompanied by subsidence of this cauldron and was followed by collapse and sliding of Paleozoic rocks from the west wall of the cauldron. Landslides in The Dell were covered by the Dell Tuff, erupted 32 m.y. ago from an unknown source to the east. An ash flow of the Needles Range

Intensive Care Units (ICUs) participating in the four editions of the Italian nosocomial infections surveillance in the ICU Network (Sorveglianza Prospettica delle Infezioni Nosocomiali nelle Unità di Terapia Intensiva, SPIN-UTI project). The isolation density of selected species of microorganisms, antibiotic resistance rates (RRs), incidence density of resistant isolates and antimicrobial usage density were calculated. RRs of carbapenem-resistant Acinetobacter baumannii, of carbapenem-resistant Klebsiella pneumoniae, of third-generation cephalosporin (3GC)-resistant K. pneumoniae and of 3GC-resistant Escherichia coli showed significant increasing trends (p ≤0.001). The consumption of each antibiotic class varied with years, although not significantly. Significant strongly positive correlations were detected between RRs and antibiotic consumption. The present study describes high RRs and increasing trends of resistant microorganisms and highlights the need for continuous comprehensive strategies targeting not only the prudent use of antibiotics, but also infection control measures to limit the epidemic spread of resistant isolates.

Upper Cretaceous and lower Eocene conglomerates of Western Transverse Ranges: evidence for tectonic rotation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Reed, W.E.; Krause, R.G.F.

1989-04-01

Stratigraphic and paleomagnetic studies have suggested that the western Transverse Ranges (WTR) microplate is allochthonous, and may have experienced translational and rotational motions. Present paleocurrent directions from the Upper Cretaceous Jalama Formation of the Santa Ynez Mountains are north-directed; these forearc sediments (Great Valley sequence) contain magmatic arc-derived conglomerate clasts from the Peninsular Ranges in southern California. Paleocurrents in the lower Eocene Juncal and Cozy Dell Formations are south-directed.

The purpose of this study was to investigate the self-perceived dental care needs and dental experiences of patients with angioedema. At the 1998 annual meeting of the Voluntary Association for the Fight, Study and Treatment of Hereditary Angioedema ("Associazione volontaria per la lotta, lo studio e la terapia dell'angioedema ereditario"), a self-administered questionnaire was distributed to participants affected by hereditary or acquired angioedema. Fifty-seven persons completed the questionnaire (37 females, 20 males; mean age, 39 +/- 17 yrs; range, 5-76). The vast majority (91%) had the hereditary form of the disease. One-third of the respondents had some problems in obtaining oral treatment, with one person having been refused care. About half of the group had experienced an acute attack following dental treatment. Preventive measures needed improvement in about two-thirds of respondents. More than half (58%) of the group perceived a need for dental care. We conclude that persons with angioedema may experience difficulty in obtaining dental treatment, a common cause of acute attacks.

E' noto che le regioni centrali degli ammassi e gruppi di galassie costituiscono un ambiente in cui gas caldo e plasma radioemittente proveniente dalle galassie dominanti interagiscono tra loro. In particolare, si pensa che la radioemissione dell'AGN centrale ed i suoi possibili cicli di attivita', siano strettamente legati alla presenza di cavita' e "bubbles" nel gas intergalattico. Si presentera' lo status di un progetto osservativo effettuato con il Giant Metrewave Radio Telescope (GMRT, India) su di un campione di 18 gruppi di galassie, osservati a tre frequenze radio (235 MHz, 325 MHz e 610 MHz). Lo studio della morfologia radio degli AGN centrali e la relativa analisi spettrale permettono di ottenere stime sull'eta' di questi oggetti, e sulla loro energia totale, che a loro volta sono in relazione con le proprieta' X dei gruppi stessi. Per tutti gli oggetti del campione sono disponibili osservazioni Chandra di proprieta'. Per due oggetti del campione, 4C+24.36 (al centro di AWM04) e NGC741 (al centro di RSOG17) verra' presentato uno studio dettagliato.

With the support of European Community funds, three submerged artificial reefs composed of concrete cubes, bell-shaped modules and natural rocks were deployed along the Adriatic coast of the Abruzzi Region to increase the fish population and to prevent illegal trawling. The Provincial governments of Teramo and Pescara requested the Istituto Zooprofilattico Sperimentale dell'Abruzzo e del Molise 'G. Caporale' to monitor nectobenthic populations. Three sampling operations were conducted each year for each artificial reef. The authors present the results of a study conducted between 2005 and 2007, comparing the catches from the artificial reefs with those from the control sites using several diversity indexes. Artificial reef areas revealed greater species diversity and richness than the control sites. This study demonstrates the value of artificial reefs in response to the problem of low income, non-commercial fisheries as well as to the issue of over-exploitation of halieutic resources. In addition, the authors suggest that artificial reefs may be capable of activating habitat diversification processes that will increase biodiversity.

Taming parallel I/O complexity with auto-tuning

2013-11-17

We present an auto-tuning system for optimizing I/O performance of HDF5 applications and demonstrate its value across platforms, applications, and at scale. The system uses a genetic algorithm to search a large space of tunable parameters and to identify effective settings at all layers of the parallel I/O stack. The parameter settings are applied transparently by the auto-tuning system via dynamically intercepted HDF5 calls. To validate our auto-tuning system, we applied it to three I/O benchmarks (VPIC, VORPAL, and GCRM) that replicate the I/O activity of their respective applications. We tested the system with different weak-scaling configurations (128, 2048, andmore » 4096 CPU cores) that generate 30 GB to 1 TB of data, and executed these configurations on diverse HPC platforms (Cray XE6, IBM BG/P, and Dell Cluster). In all cases, the auto-tuning framework identified tunable parameters that substantially improved write performance over default system settings. In conclusion, we consistently demonstrate I/O write speedups between 2x and 100x for test configurations.« less

2004-01-01

Preauricular sinuses (ear pits) are common congenital abnormalities. Usually asymptomatic, they manifest as small dells adjacent to the external ear near the anterior margin of the ascending limb of the helix, most frequently on the right side. Preauricular sinuses can be either inherited or sporadic. When inherited, they show an incomplete autosomal dominant pattern with reduced penetrance and variable expression. They may be bilateral, increasing the likelihood of being inherited, in 25-50% of cases. Preauricular sinuses are features of other conditions or syndromes in 3-10% of cases, primarily in association with deafness and branchio-oto-renal (BOR) syndrome. When other congenital anomalies coexist with these sinuses, auditory testing and renal ultrasound should be considered. Sinuses may become infected, most commonly with gram-positive bacteria, in which case their exudates should be cultured and appropriate antibiotics administered. Recurrent infection is a clear indication for complete excision and provides the only definitive cure. Recurrence rates after surgery range from 9% to 42%. Meticulous excision by an experienced head and neck surgeon minimizes the risk of recurrence.

Elettrodinamica classica

NASA Astrophysics Data System (ADS)

Lechner, Kurt

Nella scoperta della Relatività Ristretta l'Elettrodinamica, rappresentando una teoria relativistica per eccellenza, ha giocato un ruolo fondamentale. Il principio di relativit` a einsteiniana, che afferma che tutte le leggi della fisica devono avere la stessa forma in tutti i sistemi di riferimento inerziali, è emerso con forza da questa teoria ed è andato consolidandosi sempre di più, man mano che le nostre conoscenze del mondo microscopico sono diventate più complete: tutte le interazioni fondamentali rispettano infatti tale principio. Il modo più semplice ed elegante per implementarlo — difatti l'unico di un'utilità concreta — è rappresentato dal paradigma della covarianza a vista nell'ambito del calcolo tensoriale. Questo paradigma è stato applicato con successo a tutte le teorie di carattere fondamentale, come le teorie che descrivono le quattro interazioni fondamentali e le più speculative teorie di superstringa, e mantiene la sua piena efficacia anche in teoria quantistica. La nostra esposizione dell'Elettrodinamica classica si baserà dunque a ragione su questo paradigma.

Twenty varieties of field-grown potato were stored for 2 months and 6 months at 8 °C. Mean acrylamide contents in crisps prepared from all varieties at both storage times ranged from 131 μg/kg in Verdi to 5360 μg/kg in Pentland Dell. In contrast to previous studies, the longer storage period did not affect acrylamide formation significantly for most varieties, the exceptions being Innovator, where acrylamide formation increased, and Saturna, where it decreased. Four of the five varieties designated as suitable for crisping produced crisps with acrylamide levels below the European Commission indicative value of 1000 μg/kg (Saturna, Lady Rosetta, Lady Claire, and Verdi); the exception was Hermes. Two varieties more often used for French fries, Markies and Fontane, also produced crisps with less than 1000 μg/kg acrylamide. Correlations between acrylamide, its precursors and crisp colour are described, and the implications of the results for production of potato crisps are discussed. PMID:25842300

This study quantifies the changes in bone height noted in the body of the edentulous mandibles when the load of the complete denture is born by an RA Ramus Frame Implant (Pacific Implant, Rio Dell, Calif). Eighty-three patients with implants were followed for 3 to 24 years. Pre- and postoperative panoramic films were taken and again at each succeeding 5-year follow-up. The results of the bone changes were gathered retrospectively and calculated. The data revealed a significant increase in bone height from 4.413 to 13 mm and statistically significant P values of <.0003 were determined. The growth of bone appears to be influenced by the design of the posterior feet, dominant chewing side, and a range of extreme atrophy from 5.9 mm to 15 mm. Also, the previously lost anatomical structures appear to repair, such as the luman of the mental foramen and the superior wall over the inferior alveolar canal. All mandibles were loaded postoperatively with an appliance having cutting bars and porcelain teeth or just porcelain teeth in both appliances.

RIASSUNTO. Il disturbo da uso di alcol (DUA) è uno dei disturbi psichiatrici più comuni nella popolazione generale. Il DUA è caratterizzato da un pattern di bere eccessivo, che si mantiene nonostante gli effetti negativi che l'alcol ha sul funzionamento lavorativo, sulla salute, sulle problematiche legali, sull'educazione e sulla vita sociale. Attualmente, il modello bio-psico-sociale è quello che spiega meglio il DUA. Infatti, molte ricerche hanno fornito evidenze su come il DUA sia una patologia multidimensionale. Variabili biologiche, psicologiche e socio-culturali entrano in gioco nell'eziologia, nella natura, nel mantenimento e nel cambiamento nel tempo del disturbo. La fase diagnostica è un momento importante del processo di cura, perché il successo del trattamento dipende in larga misura dall'esattezza e dall'adeguatezza della diagnosi. La diagnosi clinica si basa su una valutazione globale del funzionamento del paziente e utilizza il colloquio e gli strumenti psicometrici come mezzo di raccolta di informazioni. Questo articolo fornirà una panoramica delle dimensioni psicologiche più importanti da valutare e sui migliori strumenti psicometrici da usare per una diagnosi adeguata.

A geochronological study of mafic and acidic lavas from Veneto Volcanic province (North-East Italy)

2017-04-01

The Veneto Volcanic Province (VVP), in the North-East of Italy represents one of the most important magmatic province of the Adria Plate. VVP magmatism occurred in a period ranging from late Paleocene to late Oligocene (De Vecchi et al., 1976). Five main volcanic districts can be defined from north-west to south-east: Val d'Adige, Marosticano, Lessini Hills, Berici Hills and Euganean Hills. Most of the volcanic products are relatively undifferentiated lavas, ranging in compostion from mela-nephelinites to quartz-normative tholeiites (Beccaluva et al., 2007). By contrast in the Euganean Hills volcanic and subvolcanic rocks range from subordinate basalts to prevalently acidic types, mostly quartz-trachytes and rhyolites (Milani et al., 1999). Despite of the deep petrological knowledge about this province, the radioisotopic ages of the related volcanic activities for each district are still poorly defined or even totally missing. 40Ar/39Ar ages on 9 samples have been obtained to determine the age range for the VVP. 40Ar/39Ar whole rock step heating analyses yielded ages ranging from 40.7 ± 0.2 Ma to 23.3 ± 1.5 Ma for basanites of Val d'Adige and Marosticano area, respectively. For the Lessinean district, 40Ar/39Ar whole rock analyses for two basanites, one trachybasalt and one alkali basalt close to 40 Ma, while a tholeiite from the same area yielded the youngest age for this district (i.e. 32.9 ± 1.8 Ma). This young age is comparable to 40Ar/39Ar ages obtained for the Euganean Hills intermediate-acidic rocks (Jourdan, pers. comm., 2016), suggesting a time-related shift from more alkaline to Si-saturated magmatism in the whole province.

On 10 March 2010, because of the heavy rainfall in the preceding days, the Montaguto landslide (Southern Italy) reactivated, affecting both state road 90 Delle Puglie and the Rome-Bari railway. A similar event occurred on May 2005 and on September 2009. As a result, the National Civil Protection Department (DPC) started an accurate monitoring and analysis program. A monitoring project using the GB-InSAR (ground-based interferometric synthetic aperture radar) system was emplaced to investigate the landslide kinematics, plan urgent safety measures for risk mitigation and design long-term stabilization work.Here, we present the GB-InSAR monitoring system results and its applications in the observational method (OM) approach. GB-InSAR is an established instrument for long-term campaigns aimed at early warning and monitoring during construction works. Our paper further develops these aspects in that it highlights how the OM based on the GB-InSAR technique can produce savings in terms of cost and time in engineering projects without compromising safety. This study focuses on the key role played by the monitoring activities during the design and planning activities, with special reference to the emergency phase.

Estimation of lake water - groundwater interactions in meromictic mining lakes by modelling isotope signatures of lake water.

A method is presented to assess lake water-groundwater interactions by modelling isotope signatures of lake water using meteorological parameters and field data. The modelling of delta(18)O and deltaD variations offers information about the groundwater influx into a meromictic Lusatian mining lake. Therefore, a water balance model is combined with an isotope water balance model to estimate analogies between simulated and measured isotope signatures within the lake water body. The model is operated with different evaporation rates to predict delta(18)O and deltaD values in a lake that is only controlled by weather conditions with neither groundwater inflow nor outflow. Comparisons between modelled and measured isotope values show whether the lake is fed by the groundwater or not. Furthermore, our investigations show that an adaptation of the Craig and Gordon model [H. Craig, L.I. Gordon. Deuterium and oxygen-18 variations in the ocean and the marine atmosphere. In Stable Isotopes in Oceanographic Studies and Paleotemperature, Spoleto, E. Tongiorgi (Ed.), pp. 9-130, Consiglio Nazionale delle Ricerche, Laboratorio di Geologia Nucleare, Pisa (1965).] to specific conditions in temperate regions seems necessary.

In vivo measurement of loads and pressures acting on articular cartilage in the knee joint during various activities and rehabilitative therapies following focal defect repair will provide a means of designing activities that encourage faster and more complete healing of focal defects. It was the goal of this study to develop a totally portable monitoring system that could be used during various activities and allow continuous monitoring of forces acting on the knee. In order to make the monitoring system portable, a handheld computer with custom software, a USB powered miniature wireless receiver and a battery-powered coil were developed to replace a currently used computer, AC powered bench top receiver and power supply. A Dell handheld running Windows Mobile operating system(OS) programmed using Labview was used to collect strain measurements. Measurements collected by the handheld based system connected to the miniature wireless receiver were compared with the measurements collected by a hardwired system and a computer based system during bench top testing and in vivo testing. The newly developed handheld based system had a maximum accuracy of 99% when compared to the computer based system. PMID:19789715

Opera and neuroscience.

Lorusso, Lorenzo; Franchini, Antonia Francesca; Porro, Alessandro

2015-01-01

Opera is the most complete form of theatrical representation, characterized by musical accompaniment, both instrumental and vocal. It has played an important role in sociocultural spheres, affecting the various social strata and reflecting customs and ideas in different centuries. Composers have created pieces that have also shown the development of medicine. Since the birth of opera in seventeenth century in Italy, neuroscience has played an important role in influencing the representation of madness and neurological aspects. From the Folly of the Renaissance, a path toward a representation of madness was developed, initially linked to the myths of classical antiquity. In the seventeenth and eighteenth centuries, madness was represented as comical or funny, of a loving nature and influenced by the spread of the Commedia dell'Arte (Comedy of Art). In the nineteenth century, with the rise of the first scientific theories of the mind, insanity took more precise connotations and was separated from other psychiatric and neurological diseases. The operas of the twentieth century depicted psychiatric and neurological diseases, taking into account newer medical and scientific discoveries. © 2015 Elsevier B.V. All rights reserved.

Investigation of flow in data rack

2012-04-01

The main purpose of this paper was to set up a functioning numerical model of data rack verified by an experimental measurement. The verification of the numerical model was carried out by means of the PIV method (Particle Image Velocimetry). The numerical model was "found" while using the assumed and preset values from the experimental measurement which represent boundary conditions. The server model was conceived as a four-channel with a controlled flow rate without simulation of heat transfer. The flow rate in each channel was implemented by means of pressure loss. The numerical model was further used for simulation of several phases and configurations of data rack (21U rack space) fitted with two server workstations Dell Precision R5400. The flow field in the inlet of data rack in the front of the workstations were observed and evaluated in such a way that a 2U-dimensional free space between the workstations was being left and the remaining inlet space was blanked-off/fully opened. The results of this paper will serve for designing optimization treatment of data rack from the viewpoint of cooling efficiency both within the data rack and within the data center design.

Opuntia ficus-indica L. Miller fruits, particularly 'Ficodindia dell'Etna' of Biancavilla (POD), 'Fico d'india tradizionale di Roccapalumba' with protected brand and samples from an experimental field in Pezzolo (Sicily) were analyzed by inductively coupled plasma mass spectrometry in order to determine the multi-element profile. A multivariate chemometric approach, specifically principal component analysis (PCA), was applied to individuate how mineral elements may represent a marker of geographic origin, which would be useful for traceability. PCA has allowed us to verify that the geographical origin of prickly pear fruits is significantly influenced by trace element content, and the results found in Biancavilla PDO samples were linked to the geological composition of this volcanic areas. It was observed that two principal components accounted for 72.03% of the total variance in the data and, in more detail, PC1 explains 45.51% and PC2 26.52%, respectively. This study demonstrated that PCA is an integrated tool for the traceability of food products and, at the same time, a useful method of authentication of typical local fruits such as prickly pear. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

CpG DNA in the prevention and treatment of infections.

PubMed

Dalpke, Alexander; Zimmermann, Stefan; Heeg, Klaus

2002-01-01

Microbial infection is sensed by Toll-like receptors (TLRs) on innate immune cells. Among the ten so far defined TLRs, TLR9 and its ligand are peculiar. TLR9 recognises bacterial DNA characterised by the abundance of unmethylated CpG dinucleotides, which distinguish bacterial DNA (CpG DNA) from mammalian DNA. Moreover, TLR9 shows a restricted cellular and subcellular pattern of expression. In contrast to other TLR agonists, CpG DNA is superior in activation of dendritic dells and induction of costimulatory cytokines such as interleukin (IL)-12 and IL-18. This qualifies CpG DNA as a Th1-promoting adjuvant. During infection, recognition of CpG DNA of intracellular pathogens skews and fine-tunes the ongoing immune response and induces long-lasting Th1 milieus. Thus, CpG DNA might play an important role in driving the immune system to a Th1 profile, preventing undesired Th2 milieus that might favour induction of allergic responses. Since CpG DNA can be synthesised with high purity and sequence fidelity, synthetic CpG DNA will become an important agent for Th1 instruction and be an effective adjuvant during vaccination.

New Italian lesbian, gay and bisexual psychotherapy guidelines: A review.

PubMed

Lingiardi, Vittorio; Nardelli, Nicola; Drescher, Jack

2015-01-01

Although homosexuality was depathologized in the last century and the majority of mental health professionals consider it to be a normal variant of human sexuality, some psychologists and psychiatrists still have negative attitudes toward lesbian, gay and bisexual (LGB) clients. Sometimes they provide interventions aimed at changing sexual orientation through 'reparative' or 'conversion' therapies. At other times their interventions are influenced by anti-gay prejudices or simply by lack of knowledge about sexual minorities. This paper argues for the need for appropriate treatment guidelines aimed at providing bias-free, respectful, and effective interventions given that Italian health associations have delayed providing them. Some of the main guidelines recently approved by the Consiglio Nazionale dell'Ordine degli Psicologi (National Council of the Italian Association of Psychologists) are presented. Issues addressed include differences between gender and sexual orientation, minority stress, including perceived stigma and internalized stigma, homophobic bullying, coming out, and resilience. Respectful listening to LGB and questioning clients, affirming their identities and fostering a sense of resilience are essential requirements for all mental health professionals wishing to provide effective interventions in a society where sexual minorities are subjected to discrimination throughout their entire life cycle.

The influence of phonological priming on variability in articulation

NASA Astrophysics Data System (ADS)

Babel, Molly E.; Munson, Benjamin

2004-05-01

Previous research [Sevald and Dell, Cognition 53, 91-127 (1994)] has found that reiterant sequences of CVC words are produced more quickly when the prime word and target word share VC sequences (i.e., sequences like sit sick) than when they are identical (sequences like sick sick). Even slower production rates are found when primes and targets share a CV sequence (sequences like kick sick). These data have been used to support a model of speech production in which lexical items and their constituent phonemes are activated sequentially. The current experiment investigated whether phonological priming also influences variability in the acoustic characteristics of words. Specifically, we examined whether greater variability in the acoustic characteristics of target words was noted in the CV-related prime context than in the identical-prime context, and whether less variability was noted in the VC-related context. Thirty adult subjects with typical speech, language, and hearing ability produced reiterant two-word sequences that varied in their phonological similarity. The duration, first, and second formant frequencies of the target-words' vowels were measured. Preliminary analyses indicate that phonological priming does not have a systematic effect on variability in these acoustic parameters.

This paper focuses on chemical composition of the epiphytic moss Leptodon smithii, gathered on Quercus ilex bark, assessed in seven sites located in urban and extra-urban/remote areas of southern Italy, a poorly surveyed geographic area. The concentrations of Cr, Cu, Pb and Zn in moss tissue are generally more abundant in moss gathered in the urban sites; among extra-urban/remote sites Valle delle Ferriere showed the highest metal concentrations, mostly related to an industrial activity occurred in the past. L. smithii chemistry seems influenced by airborne dust locally enhanced by erosion phenomena, long-range transport of pollutants and marine aerosols. Element content in moss is compared with genetic variability of L. smithii estimated in the same sites. Pearson's correlation coefficient between gene diversity and total element load (r=-0.851; p=0.03) suggests that anthropogenic pressure, determining habitat disturbance and fragmentation, leads both to genetic impoverishment consequent to population shrink, and to a higher accumulation in moss tissues, as a consequence of increased airborne major/trace elements. Thus, the coupled evaluation of chemical composition in mosses and gene diversity may prove a useful tool to highlight environmental disturbance in a gradient of land use.

The MAGIC-5 CAD for nodule detection in low dose and thin slice lung CTs

Lung cancer is the leading cause of cancer-related mortality in developed countries. Only 10-15% of all men and women diagnosed with lung cancer live 5 years after the diagnosis. However, the 5-year survival rate for patients diagnosed in the early asymptomatic stage of the disease can reach 70%. Early-stage lung cancers can be diagnosed by detecting non-calcified small pulmonary nodules with computed tomography (CT). Computer-aided detection (CAD) could support radiologists in the analysis of the large amount of noisy images generated in screening programs, where low-dose and thin-slice settings are used. The MAGIC-5 project, funded by the Istituto Nazionale di Fisica Nucleare (INFN, Italy) and Ministero dell'Università e della Ricerca (MUR, Italy), developed a multi-method approach based on three CAD algorithms to be used in parallel with a merging of their results: the Channeler Ant Model (CAM), based on Virtual Ant Colonies, the Dot-Enhancement/Pleura Surface Normals/VBNA (DE-PSN-VBNA), and the Region Growing Volume Plateau (RGVP). Preliminary results show quite good performances, to be improved with the refining of the single algorithm and the added value of the results merging.

2010-02-01

The present study provides a set of objective age of acquisition (AoA) norms for 223 Italian words that may be useful for conducting cross-linguistic studies or experiments on Italian language processing. The data were collected by presenting children from the ages of 2 to 11 with a normed picture set (Lotto, Dell'Acqua, & Job, 2001). Following the study of Morrison, Chappell, and Ellis (1997), we report two measures of objective AoA. Both measures strongly correlated with each other, and they also showed a good correlation with the rated AoA provided by adult participants. Furthermore, we assessed the relationship between the AoA measures and other variables used in psycholinguistic experiments. Regression analyses showed that familiarity, typicality, and word frequency were significant predictors of AoA. AoA, but not word frequency, was found to determine naming latencies. Finally, we present a path model in which AoA is a mediator in predicting speed in picture naming. The norms and the picture set can also be downloaded from http://dpss.psy.unipd.it/files/strumenti.php and from http://brm.psychonomic-journals.org/content/supplemental.

We parallelized the GeoClaw code on one-level grid using OpenMP in March, 2011 to meet the urgent need of simulating tsunami waves at near-shore from Tohoku 2011 and achieved over 75% of the potential speed-up on an eight core Dell Precision T7500 workstation [1]. After submitting that work to SC11 - the International Conference for High Performance Computing, we obtained an unreleased OpenMP version of GeoClaw from David George, who developed the GeoClaw code as part of his PH.D thesis. In this paper, we will show the complementary characteristics of the two approaches used in parallelizing GeoClaw and the speed-up obtained by combining the advantage of each of the two individual approaches with adaptive mesh refinement (AMR), demonstrating the capabilities of running GeoClaw efficiently on many-core systems. We will also show a novel simulation of the Tohoku 2011 Tsunami waves inundating the Sendai airport and Fukushima Nuclear Power Plants, over which the finest grid distance of 20 meters is achieved through a 4-level AMR. This simulation yields quite good predictions about the wave-heights and travel time of the tsunami waves. ?? 2011 IEEE.

OBIETTIVI: valutare lo stato di salute della popolazione residente nel comune di Manfredonia dal 1970 al 2013. DISEGNO: analisi descrittiva dell'andamento temporale della mortalità generale, per gruppi di cause, dal 1970 al 2013. SETTING E PARTECIPANTI: i dati di mortalità e le popolazioni residenti sono di fonte Istat. Sono state esaminate 55 cause di decesso. Le analisi sono disaggregate per sesso e periodo. PRINCIPALI MISURE DI OUTCOME: sono stati elaborati i rapporti standardizzati di mortalità (SMR%), con i rispettivi intervalli di confidenza al 90% (IC90%), e i tassi di mortalità standardizzati col metodo diretto (TSD ). RISULTATI: lo stato di salute misurato dal tasso di mortalità per tutte le cause migliora nel tempo: i TSD passano da 92 x10.000 negli anni 1970-1974 a 52 x10.000 nel biennio 2012-2013 negli uomini, da 70 x10.000 a 39 x10.000 nelle donne. Tuttavia, rispetto alla media regionale Manfredonia perde progressivamente il suo vantaggio, passando da -20% a -10% negli uomini, e da -20% a +1,5% nelle donne. Questo andamento è molto evidente per il complesso delle cause cardiovascolari, mentre i tumori maligni sono in generale nella media regionale. Nell'ultimo periodo disponibile per causa di decesso (2006-2011), la mortalità per infarto miocardico è stata più alta della media regionale (uomini: +35%; donne: +54%). I rapporti standardizzati di mortalità (SMR) mostrano tra gli uomini valori in crescita, in particolar modo rispetto al riferimento provinciale, con un eccesso a cominciare dal periodo 2006-2011 (22 decessi/anno e 19 attesi; SMR%: 117,2; IC90% 101,1-135,2; riferimento: provincia di Foggia). Anche tra le donne gli SMR% superano i riferimenti provinciali negli ultimi periodi esaminati (nel 2012-2013: 7 decessi/ anno e 4,2 attesi; SMR%: 116,4; IC90% 97,0-260,7; riferimento: provincia di Foggia). CONCLUSIONI: la mortalità a Manfredonia è diminuita in misura minore rispetto a quella osservata nei riferimenti provinciali e regionali

Patients with esophageal symptoms potentially associated to esophageal motor disorders such as dysphagia, chest pain, heartburn and regurgitation, represent one of the most frequent reasons for referral to gastroenterological evaluation. The utility of esophageal manometry in clinical practice is: (1) to accurately define esophageal motor function, (2) to identify abnormal motor function, and (3) to establish a treatment plan based on motor abnormalities. With this in mind, in the last decade, investigations and technical advances, with the introduction of high-resolution esophageal manometry, have enhanced our understanding and management of esophageal motility disorders. The following recommendations were developed to assist physicians in the appropriate use of esophageal manometry in modern patient care. They were discussed and approved after a comprehensive review of the medical literature pertaining to manometric techniques and their recent application. This position statement created under the auspices of the Gruppo Italiano di Studio per la Motilità dell'Apparato Digerente (GISMAD), Società Italiana di Gastroenterologia ed Endoscopia Digestiva (SIGE) and Associazione Italiana Gastroenterologi ed Endoscopisti Digestivi Ospedalieri (AIGO) is intended to help clinicians in applying manometric studies in the most fruitful manner within the context of their patients with esophageal symptoms.

The paleogene stratigraphic sequence exposed in the southwestern San Rafael Mountains at the southern terminus of the Coast Ranges, consists of up to 850 m (2,800 ft) of the marine limestone, sandstone, and mudstone that lies with a unique depositional contact upon Franciscan Complex rocks. Lithofacies identified represent four sedimentary environments: (1) foreslope talus deposits of a neritic algal bank (Sierra Blanca limestone), (2) bathyal basin plain and outer submarine fan deposits (Juncal/Anita Formation and Cozy Dell Shale), (3) suprafan lobe deposits of a bathyal submarine fan (lower Mitilija Sandstone), and (4) sublittoral shelf deposits (upper Matilija Sandstone). Similarities betweenmore » paleogene rocks in the southwest San Rafael mountains and the western Santa Ynez Mountains of the Transverse Ranges, approximately 60 km (40 mi) to the west, suggest deposition in a similar paleogeographic setting. Paleomagnetic data suggests post-Paleogene clockwise rotations of the western Transverse Ranges of 90{degree}+. Counterclockwise rotation of the western Transverse Ranges by this amount aligns the similar depositional sequences of the western Transverse Ranges with the northwest-trending Paleogene forearc basin of the southern Coast Ranges and eliminates the necessity for an east-west-oriented Paleogene basin at the site of the present western Transverse Ranges.« less

Application of the Kohonen artificial neural network in the identification of proteinaceous binders in samples of panel painting using gas chromatography-mass spectrometry.

Historically, three types of proteinaceous matter--casein, egg and animal glue--were used as binders for pigments or as adhesives in easel and wall painting. The relative percentage content of alanine, glycine, valine, leucine, isoleucine, serine, tyrosine, phenylalanine, aspartic acid, glutamic acid, lysine, methionine, proline and hydroxyproline, as determined by GC-MS, is used for binder identification. In this paper we analyse the viability of a multivariate modelling using Kohonen's neural network to characterise the wood adhesive in 16 old samples from Italian panel paintings of the 12-16th centuries. As a training set we use the amino acid composition of 141 samples contributed by the Opificio delle Pietre Dure of Florence (Cultural Heritage Ministry, Italy). Of the 141 samples, 113 were used to train the Kohonen neural network and the remaining 28 as the evaluation set. A specificity and sensitivity of 100% was achieved in training and 92-100% in prediction depending on the assignation criteria employed. The neural network thus trained and evaluated was applied to the old samples, achieving identification of all of them. In addition, the map obtained for each amino acid provides relevant information as to its importance in the characterisation of the sample.

NET (Microsoft) components, using an SQL Server 2005 (Microsoft) for data storage with Windows Mobile (Microsoft) operating system. The PDA devices were Dell Axim. System functions and user interfaces were specified for MobilDent. User interfaces for PDA, back-office and database systems were based on. NET programming. The PDA user interface was based on Windows suitable to a PDA display, whereas the back-office interface was designed for a normal-sized computer screen. A synchronisation module (MS Active Sync, Microsoft) was used to enable download of field data from PDA to the database. MobilDent is a feasible application for oral health assessment fieldwork, and the oral health assessment database may prove a valuable source for care planning, educational and research purposes. Further development of the MobilDent system will include wireless connectivity with download-on-demand technology.

Interplay between Self-Assembled Structures and Energy Level Alignment of Benzenediamine on Au(111) Surfaces

NASA Astrophysics Data System (ADS)

Li, Guo; Neaton, Jeffrey

2015-03-01

Using van der Waals-corrected density functional theory (DFT) calculations, we study the adsorption of benzene-diamine (BDA) molecules on Au(111) surfaces. We find that at low surface coverage, the adsorbed molecules prefer to stay isolated from each other in a monomer phase, due to the inter-molecular dipole-dipole repulsions. However, when the coverage rises above a critical value of 0.9nm-2, the adsorbed molecules aggregate into linear structures via hydrogen bonding between amine groups, consistent with recent experiments [Haxton, Zhou, Tamblyn, et al, Phys. Rev. Lett. 111, 265701 (2013)]. Moreover, we find that these linear structures at high density considerably reduces the Au work function (relative to a monomer phase). Due to reduced surface polarization effects, we estimate that the resonance energy of the highest occupied molecular orbital of the adsorbed BDA molecule relative to the Au Fermi level is significantly lower than the monomer phase by more than 0.5 eV, consistent with the experimental measurements [DellAngela, Kladnik, and Cossaro, et al., Nano Lett. 10, 2470 (2010)].

Recently, the electronic properties and alignment of tetramethyl-1,4-benzenediamine (TMBDA), 1,4-benzenediamine (BDA) and tetrafluro-1,4-benzenediamine (TFBDA) molecules were studied experimentally. Discrepancies were found for both the binding energy and the molecule tilt angle with respect to the surface, when results were compared with density functional theory calculations [1]. We have included the effect of vdW interactions both between the molecules and the Au(111) surface and find binding energies which are in very good agreement with experiments. We also find that at low coverages each of these molecules would adsorb almost parallel to the surface. N-Au bond lengths and charge redistribution on adsorption of the molecules are also analyzed. Our calculations are based on DFT using vdW-DF exchange correlation functionals. For BDA (since we are aware of experimental data), we show that for higher coverage, inclusion of intermolecular van der Waals interaction leads to tilting of the molecules with respect to the surface and formation of line structures. Our results demonstrate the central role played by intermolecular interaction in pattern formation on this surface.[4pt] [1] M. Dell'Angela et al, Nano Lett. 2010, 10, 2470; M. Kamenetska et al, J.

Nowadays, leptospirosis is a re‑emerging widespread infectious disease often underestimate worldwide. The National Reference Centre for Leptospirosis (NRCL), at the Istituto Zooprofilattico Sperimentale della Lombardia e dell'Emilia Romagna, Brescia (Italy), with the cooperation of all the other Istituti Zooprofilattici Sperimentali (IIZZSS), evaluated the distribution of such important zoonosis in Italy. Serological data obtained between 2010‑2011 by each laboratory were collected by the NRCL and discussed. Serum samples collected from 43,935 animal specimens were analysed by the Microscopic Agglutination Test (MAT), using a panel of 8 serogroups as antigens (Australis, Ballum, Canicola, Grippotyphosa, Icterohaemorrhagiae, Pomona, Sejroe, Tarassovi). A MAT cut‑off of 1:100 was used to identify the serological positivities, 6,279 sera showed positive titers. Bovine (46.9%), swine (27.5%), ovine and goat (7.4%), dog (6.9%), and wild boar (4.5%) samples were delivered to the Laboratories more frequently than equine and other species sera. Data analysis showed that the most common serogroups in Italy are: Australis present in dogs, wild boars, horses, hares, swine, foxes, and rodents; Sejroe detected in cattle, sheep, goats, and buffaloes; Icterohaemorrhagiae present in dogs, goats, and foxes; Pomona detected in swine, cattle, and wild species; Grippotyphosa reported in hares.

This paper presents an analytical GC-MS procedure to study the chemical composition of plant gums, determining aldoses and uronic acids in one step. The procedure is based on the silylation of aldoses and uronic acids, released from plant gums by microwave assisted hydrolysis, and previously converted into the corresponding diethyl-dithioacetals and diethyl-dithioacetal lactones. Using this method only one peak for each compound is obtained, thus providing simple and highly reproducible chromatograms. The analytical procedure was optimised using reference samples of raw plant gums (arabic, karaya, ghatti, guar, locust bean and tragacanth, cherry, plum and peach gums), commercial watercolours and paint layers prepared according to ancient recipes at the Opificio delle Pietre Dure of Florence (Italy). To identify gum media in samples of unknown composition, a decisional schema for the gum identification and the principal component analysis of the relative sugar percentage contents were employed. The procedure was used to study samples collected from wall paintings from Macedonian tombs (4th-3rd centuries bc) and from the Mycenaean "Palace of Nestor" (13th century bc) in Pylos, Greece. The presence of carbohydrates was ascertained and plant gum binders (fruit and a mixture of tragacanth and fruit tree gums) were identified in some of the samples.

Problems Caused by Microbes and Treatment Strategies Downstream Petroleum Microbiology - An Industry Perspective

NASA Astrophysics Data System (ADS)

McFarlane, Elaine

In the mid 1800's it was discovered that crude oil could be extracted and exploited to produce energy. However, it was the invention of the first four-stroke internal combustion engine in 1876 that transformed the petroleum industry from a localised to a global business (Dell and Rand, 2004). Crude oil is made into useable products at the refinery via separation, conversion and treatment processes. Separation starts with distillation where the crude is evaporated and condensed into fractions based on their boiling ranges (Fig. 19.1). As well as carbon and hydrogen, the fractions consist of sulphur, nitrogen and oxygen (present in low concentrations) and metals like copper and iron (in trace amounts). After separation, heavy fractions are converted into lighter ones using intense heat, pressure and a catalyst to speed up chemical reactions. Molecules like sulphur can then be stripped out by heat treatment under pressure with hydrogen. Injection of refinery additives makes a finished fuel. For example, static dissipator is added to Automotive Gas Oil (AGO) to reduce the risk of spark and explosion during fuel movements; middle distillate flow improver to improve low temperature operability and lubricity improver to lubricate engine components. Finally, fuel quality measurements are made to ensure that the finished fuel meets the relevant specification.

Here we are going to introduce our most recent results, after the last immersions and a 3D bathymetrical survey completed by echo-side scan sonar in Tramonto Lake at Gambulaga, explaining the connection with remote sensing investigations and direct surveys applied to underwater archaeology of the inland water. The main submerged structure individuated is a part of wooden dock on the left side of Padus, in front of the Necropolis of Fadieni (1st-3rd cent. A.D.). Thanks to the study of 183 finds coming from the lake, involving students and young collaborators of the Archaeological National Museum of Ferrara, we are reconstructing the ancient landscape between Proto-Imperial Age and Late Antique.

Structure of multiphoton quantum optics. II. Bipartite systems, physical processes, and heterodyne squeezed states

Extending the scheme developed for a single mode of the electromagnetic field in the preceding paper [F. Dell'Anno, S. De Siena, and F. Illuminati, Phys. Rev. A 69, 033812 (2004)], we introduce two-mode nonlinear canonical transformations depending on two heterodyne mixing angles. They are defined in terms of Hermitian nonlinear functions that realize heterodyne superpositions of conjugate quadratures of bipartite systems. The canonical transformations diagonalize a class of Hamiltonians describing nondegenerate and degenerate multiphoton processes. We determine the coherent states associated with the canonical transformations, which generalize the nondegenerate two-photon squeezed states. Such heterodyne multiphoton squeezed states are defined asmore » the simultaneous eigenstates of the transformed, coupled annihilation operators. They are generated by nonlinear unitary evolutions acting on two-mode squeezed states. They are non-Gaussian, highly nonclassical, entangled states. For a quadratic nonlinearity the heterodyne multiphoton squeezed states define two-mode cubic phase states. The statistical properties of these states can be widely adjusted by tuning the heterodyne mixing angles, the phases of the nonlinear couplings, as well as the strength of the nonlinearity. For quadratic nonlinearity, we study the higher-order contributions to the susceptibility in nonlinear media and we suggest possible experimental realizations of multiphoton conversion processes generating the cubic-phase heterodyne squeezed states.« less

Preliminary raptor surveys in western Mongolia

Raptors were observed on a 5200 km expedition from Ulaan Baatar through the Hangay Mountains to the Russian Altay Mountains with return through the Gobi Altay Mountains. The focus of the expedition was on nesting ecology of the Saker (Falco cherrug) and Altay falcons (F. altaicus) (25 eyries were located), but nests were also found for seven other species including more than 30 nests found of the upland buzzard (Buteo hemilasius). We conducted 21 day-long counts and 10 more formal raptor road counts. Raptors were concentrated in areas where perches were common and where food was most abundant. Western Mongolia remains a vast undeveloped land where camel trains and yak carts are normal. No developed highway network exists. Raptor work in the interior must be supported by four-wheel drive vehicles traveling cross country. Food and fuel for a research team are difficult to procure, but raptor populations are largely unexploited. Raptors frequently nest on the ground or on very low cliffs and tress, and often nest in close proximity of pairs of their own and other species. Several areas of special significance to raptors are discussed including the Taleen Ulaan (Red Steppe) areas of granite dells which we recommend for status as an international reserve.

Phase and Index of Refraction Imaging by Hyperspectral Reflectance Confocal Microscopy.

Selci, Stefano

2016-12-16

A hyperspectral reflectance confocal microscope (HSCM) was realized by CNR-ISC (Consiglio Nazionale delle Ricerche-Istituto dei Sistemi Complessi) a few years ago. The instrument and data have been already presented and discussed. The main activity of this HSCM has been within biology, and reflectance data have shown good matching between spectral signatures and the nature or evolution on many types of cells. Such a relationship has been demonstrated mainly with statistical tools like Principal Component Analysis (PCA), or similar concepts, which represent a very common approach for hyperspectral imaging. However, the point is that reflectance data contains much more useful information and, moreover, there is an obvious interest to go from reflectance, bound to the single experiment, to reflectivity, or other physical quantities, related to the sample alone. To accomplish this aim, we can follow well-established analyses and methods used in reflectance spectroscopy. Therefore, we show methods of calculations for index of refraction n , extinction coefficient k and local thicknesses of frequency starting from phase images by fast Kramers-Kronig (KK) algorithms and the Abeles matrix formalism. Details, limitations and problems of the presented calculations as well as alternative procedures are given for an example of HSCM images of red blood cells (RBC).

Verrucous skin lesions have been attributed to various herpes viruses in immunosuppressed patients, including those with human immunodeficiency virus infection (HIV). We examined such lesions from six HIV-infected patients to determine the range of microscopic findings present and to establish which herpesviruses were present. Verrucous epidermal hyperplasia, pseudocarcinomatous hyperplasia, and massive hyperkeratosis correlate with the warty clinical appearance of the lesions. Herpetic cytopathic changes, including multinucleated epidermal giant cells, steel-gray nuclei, necrotic acantholytic keratinocytes, and Cowdry type A nuclear inclusions were seen most prominently in the dells between papillations and in adnexal epithelium. In two cases, increased numbers of spindled cells were seen in the dermis. Immunoperoxidase staining with anti-type IV collagen antibodies demonstrated that these findings were not those of Kaposi's sarcoma, but represent a fibrotic reaction to the infection. Viral cultures of four of the cases demonstrated the presence of varicella-zoster virus, whose presence was detected by the polymerase chain reaction in paraffin-embedded lesional tissue from all six cases. Polymerase chain reaction did not show the presence of cytomegalovirus, herpes simplex, Epstein-Barr, or human papillomavirus. We conclude that these unusual verrucous lesions are a chronic manifestation of herpes zoster infection and that the reported presence of other agents in such lesions is probably coincidental.

AN ALTERNATIVE CALIBRATION OF CR-39 DETECTORS FOR RADON DETECTION BEYOND THE SATURATION LIMIT.

2016-12-01

Time-integrated measurements of indoor radon levels are commonly carried out using solid-state nuclear track detectors (SSNTDs), due to the numerous advantages offered by this radiation detection technique. However, the use of SSNTD also presents some problems that may affect the accuracy of the results. The effect of overlapping tracks often results in the underestimation of the detected track density, which leads to the reduction of the counting efficiency for increasing radon exposure. This article aims to address the effect of overlapping tracks by proposing an alternative calibration technique based on the measurement of the fraction of the detector surface covered by alpha tracks. The method has been tested against a set of Monte Carlo data and then applied to a set of experimental data collected at the radon chamber of the Istituto Nazionale di Metrologia delle Radiazioni Ionizzanti, at the ENEA centre in Casaccia, using CR-39 detectors. It has been proved that the method allows to extend the detectable range of radon exposure far beyond the intrinsic limit imposed by the standard calibration based on the track density. © The Author 2015.

During the recent severe outbreaks of bluetongue (BT) in the Mediterranean Basin, the BT virus (BTV) spread beyond its historical limits into the Balkan region. One of the primary impacts of BT is the cessation in livestock trade which can have severe economic and social consequences. The authors briefly describe the development of the collaborative East-BTnet programme which aims to assist all affected and at-risk Balkan states and adjoining countries in the management of BT, and in the development of individual national surveillance systems. The beneficiary countries involved, and led by the World organisation for animal health (Office International des Epizooties) Collaborating Centre for veterinary training, epidemiology, food safety and animal welfare of the Istituto Zooprofilattico dell'Abruzzo e del Molise 'G. Caporale' in collaboration with the Institute for the Protection and the Security of the Citizen, the European Commission Joint Research Centre (IPSC-JRC), were Albania, Bosnia-Herzegovina, Bulgaria, Croatia, Cyprus, the Former Yugoslavia Republic of Macedonia, Kosovo, Malta, Romania, Serbia and Montenegro, Slovenia and Turkey. A regional web-based surveillance network is a valuable tool for controlling and managing transboundary animal diseases such as BT. Its implementation in the Balkan region and in adjoining areas of south-eastern Europe is described and discussed.

RIASSUNTO. Il fenomeno delle persone senza fissa dimora sta assumendo in questi anni una rilevanza sociale devastante, con una prevalenza stimata in USA e in Europa compresa tra il 5,6% e il 13,9%. Queste persone hanno una scarsa qualità di vita, una limitata o assente vita sociale, sono spesso disoccupate o lavorano solo saltuariamente. Sono a rischio di problemi con la legge, sono spesso affette da dipendenza da droghe, da patologie psichiatriche e internistiche. L'alcol spesso non rappresenta la causa della loro condizione sociale, ma solo la conseguenza, contribuendo in questo modo al loro degrado bio-psico-sociale. Nel 2009 lo US Department of Housing and Urban Development's Homelessness Assistance Programs e nel 2010 la European Consensus Conference on Homelessness hanno segnato un grande passo avanti nella riabilitazione sociale di queste persone, utilizzando il concetto del "case management". In particolare lo Standard Case Management si è dimostrato in grado di migliorare la stabilità abitativa, di ridurre l'uso di droghe e di rimuovere le barriere lavorative. L'Assertive Community Treatment si è dimostrato, invece, in grado di migliorare la stabilità abitativa e ha un rapporto costo/beneficio migliore per i pazienti affetti da doppia diagnosi.

Biodiversity is crucial in preservation of ecosystems, and bacterial communities play an indispensable role for the functioning of marine ecosystems. The Mediterranean marine protected area (MPA) "Capo Gallo-Isola delle Femmine" was instituted to preserve marine biodiversity. The bacterial diversity associated with MPA sediment was compared with that from sediment of an adjacent harbour exposed to intense nautical traffic. The MPA sediment showed higher diversity with respect to the impacted site. A 16S rDNA clone library of the MPA sediment allowed the identification of 7 phyla: Proteobacteria (78%), Firmicutes (11%), Acidobacteria (3%), Actinobacteria (3%), Bacteroidetes (2%), Planctomycetes (2%), and Cyanobacteria (1%). Analysis of the hydrocarbon (HC)-degrading bacteria was performed using enrichment cultures. Most of the MPA sediment isolates were affiliated with Gram-positive G+C rich bacteria, whereas the majority of taxa in the harbour sediment clustered with Alpha- and Gammaproteobacteria; no Gram-positive HC degraders were isolated from the harbour sediment. Our results show that protection probably has an influence on bacterial diversity, and suggest the importance of monitoring the effects of protection at microbial level as well. This study creates a baseline of data that can be used to assess changes over time in bacterial communities associated with a Mediterranean MPA.

Hyperspectral reflectance factor image estimations were performed in the 400-700 nm wavelength range using a portable consumer-level laptop display as an adjustable light source for a trichromatic camera. Targets of interest were ColorChecker Classic samples, Munsell Matte samples, geometrically challenging tempera icon paintings from the turn of the 20th century, and human hands. Measurements and simulations were performed using Nikon D80 RGB camera and Dell Vostro 2520 laptop screen as a light source. Estimations were performed without spectral characteristics of the devices and by emphasizing simplicity for training sets and estimation model optimization. Spectral and color error images are shown for the estimations using line-scanned hyperspectral images as the ground truth. Estimations were performed using kernel-based regression models via a first-degree inhomogeneous polynomial kernel and a Matérn kernel, where in the latter case the median heuristic approach for model optimization and link function for bounded estimation were evaluated. Results suggest modest requirements for a training set and show that all estimation models have markedly improved accuracy with respect to the DE00 color distance (up to 99% for paintings and hands) and the Pearson distance (up to 98% for paintings and 99% for hands) from a weak training set (Digital ColorChecker SG) case when small representative training data were used in the estimation.

Field substitution of nonrespondents can be used to maintain the planned sample size and structure in surveys but may introduce additional bias. Sample weighting is suggested as the preferable alternative; however, limited empirical evidence exists comparing the two methods. We wanted to assess the impact of substitution on surveillance results using data from Progressi delle Aziende Sanitarie per la Salute in Italia-Progress by Local Health Units towards a Healthier Italy (PASSI). PASSI is conducted by Local Health Units (LHUs) through telephone interviews of stratified random samples of residents. Nonrespondents are replaced with substitutes randomly preselected in the same LHU stratum. We compared the weighted estimates obtained in the original PASSI sample (used as a reference) and in the substitutes' sample. The differences were evaluated using a Wald test. In 2011, 50,697 units were selected: 37,252 were from the original sample and 13,445 were substitutes; 37,162 persons were interviewed. The initially planned size and demographic composition were restored. No significant differences in the estimates between the original and the substitutes' sample were found. In our experience, field substitution is an acceptable method for dealing with nonresponse, maintaining the characteristics of the original sample without affecting the results. This evidence can support appropriate decisions about planning and implementing a surveillance system. Copyright © 2014 Elsevier Inc. All rights reserved.

Surface slope profile is commonly used to evaluate X-ray reflective optics, which is used in synchrotron radiation beam. Moreover, the measurement result of measuring instrument for X-ray reflective optics is usually the surface slope profile rather than the surface height profile. To avoid the conversion error, the slope-based figuring model is introduced introduced by processing the X-ray reflective optics based on surface height-based model. However, the pulse iteration method, which can quickly obtain the dell time solution of the traditional height-based figuring model, is not applied to the slope-based figuring model because property of the slope removal function have both positive and negative values and complex asymmetric structure. To overcome this problem, we established the optimal mathematical model for the dwell time solution, By introducing the upper and lower limits of the dwell time and the time gradient constraint. Then we used the constrained least squares algorithm to solve the dwell time in slope-based figuring model. To validate the proposed algorithm, simulations and experiments are conducted. A flat mirror with effective aperture of 80 mm is polished on the ion beam machine. After iterative polishing three times, the surface slope profile error of the workpiece is converged from RMS 5.65 μrad to RMS 1.12 μrad.

Postprandial oxidative stress is characterized by an increased susceptibility of the organism towards oxidative damage after consumption of a meal rich in lipids and/or carbohydrates. Micronutrients modulate the immune system and exert a protective action by reducing low-density lipoproteins oxidation (ox-LDL) via induction of antioxidant enzymes. The clinical study was a randomized and cross-over trial, conducted through the CONSORT flowchart. We evaluated the gene expression of 103 genes related to oxidative stress (HOSp) and human inflammasome pathways (HIp), and ox-LDL level at fasting and after 40 g raw "Tonda Gentile delle Langhe" hazelnut consumption, in association with a McDonald's® Meal (McDM) in 22 healthy human volunteers. Ox-LDL levels significantly increased comparing no dietary treatment (NDT) vs. McDM, and decreased comparing McDM vs. McDM + H (p<0.05). Percentage of significant genes expressed after each dietary treatment were the follows: (A) NDT vs. McDM: 3.88% HIp and 17.48% HOSp; (B) NDT vs. McDM + H: 17.48% HIp and 23.30% HOSp; (C) McDM vs. McDM + H: 17.48% HIp and 33.98% HOSp. Hazelnut consumption reduced post prandial risk factors of atherosclerosis, such as ox-LDL, and the expression of inflammation and oxidative stress related genes. Chronic studies on larger population are necessary before definitive conclusions.

Structure of multiphoton quantum optics. I. Canonical formalism and homodyne squeezed states

DOE Office of Scientific and Technical Information (OSTI.GOV)

Dell'Anno, Fabio; De Siena, Silvio; Illuminati, Fabrizio

2004-03-01

We introduce a formalism of nonlinear canonical transformations for general systems of multiphoton quantum optics. For single-mode systems the transformations depend on a tunable free parameter, the homodyne local-oscillator angle; for n-mode systems they depend on n heterodyne mixing angles. The canonical formalism realizes nontrivial mixing of pairs of conjugate quadratures of the electromagnetic field in terms of homodyne variables for single-mode systems, and in terms of heterodyne variables for multimode systems. In the first instance the transformations yield nonquadratic model Hamiltonians of degenerate multiphoton processes and define a class of non-Gaussian, nonclassical multiphoton states that exhibit properties of coherencemore » and squeezing. We show that such homodyne multiphoton squeezed states are generated by unitary operators with a nonlinear time evolution that realizes the homodyne mixing of a pair of conjugate quadratures. Tuning of the local-oscillator angle allows us to vary at will the statistical properties of such states. We discuss the relevance of the formalism for the study of degenerate (up-)down-conversion processes. In a companion paper [F. Dell'Anno, S. De Siena, and F. Illuminati, 69, 033813 (2004)], we provide the extension of the nonlinear canonical formalism to multimode systems, we introduce the associated heterodyne multiphoton squeezed states, and we discuss their possible experimental realization.« less

bronchial asthma is caused by inappropriate acquired immune responses to environmental allergens. It is a major health problem, with a prevalence that is rapidly increasing. Curative therapy is not currently available. to test the hypothesis that thrombomodulin (TM) inhibits allergic bronchial asthma by inducing tolerogenic dendritic cells (DCs). the protective effect of TM was evaluated using a murine asthma model. Asthma was induced in mice by exposure to chicken egg ovalbumin, and the effects of inhaled TM or TM-treated DCs were assessed by administering before ovalbumin exposure. treatment with TM protects against bronchial asthma measured as improved lung function and reduced IgE and cells in alveolar lavage fluid by inducing tolerogenic dendritic dells. These are characterized by high expression of surface TM (CD141/TM(+)) and low expression of maturation markers and possess reduced T-cell costimulatory activity. The CD141/TM(+) DCs migrate less toward chemokines, and after TM treatment there are fewer DCs in the draining lymph node and more in the lungs. The TM effect is independent of its role in coagulation. Rather, it is mediated via the TM lectin domain directly interacting with the DCs. the results of this study show that TM is a modulator of DC immunostimulatory properties and a novel candidate drug for the prevention of bronchial asthma in atopic patients.

Prophylactic Vitamin D supplementation is a common practice in Alpaca breeding in many regions around the world. An overdosage can lead to dystrophic mineralization of soft tissues. In this paper we illustrate a suspected case of hypervitaminosis D in an 8-year-old female Alpaca. In June 2015, the carcass of an 8-year-old female Alpaca ( Vicugna pacos ) was submitted to the diagnostic laboratory of the Istituto Zooprofilattico Sperimentale delle Venezie (IZSVe) for necropsy. The animal had undergone a spontaneous abortion with uterine prolapse and delivery of the placenta, and had died shortly thereafter. Death occurred due to internal haemorrhage related to dystrophic mineralization of the left renal artery with subsequent rupture and damage of the renal hilum. During the necropsy, histopathological and serum biochemical analyses were performed. After laboratory analyses and the history of mineral and vitamin supplementation reported by the breeder, a hypervitaminosis D was suspected to be the most probable cause of the dystrophic mineralization observed in the left renal artery. Most of the information regarding Llamas and Alpacas comes from the South American and Australian regions. It is therefore important to provide scientific information about these animals in other regions of the world in order to have a better and wider understanding of the nutritional and environmental conditions necessary for optimal breeding.

The History of Italian Volcanoes Revised by Archeomagnetism

The volcanoes Etna and Vesuvius are famous for their historical record, which goes back to Greek and Roman times. The name “Etna” first appears in one of Pindar's Pythian odes (475 B.C.E), and the Vesuvius outburst in 79 C.E. was reported in detail by Pliny the Younger. Other written accounts mention Stromboli and Vulcano (located on the Aeolian Islands), so it might seem that the eruptive history of these Italian volcanoes for the past few millennia is well known. This is not the case, however, because of many limitations in the historical data. There are enormous gaps due to social events such as wars, barbarian invasions, and the Dark Ages. In particular, the historical record has no valuable account at Etna from 252 to 1062 C.E. Furthermore, the preserved documents are too imprecise to identify the lavas and eruptive systems. Most of the ages prior to 1700 C.E. displayed in the present research catalogs were attributed by pioneering geologists in the 1800s on the mere basis of the morphology of flows. These estimates remained unchanged for nearly a century—for example, the Atlas de L'Etna by Sartorius von Waltershausen [1845] was used unaltered for age attribution of “historical lavas” in much more recent geological maps [e.g., Consiglio Nazionale delle Ricerche (CNR), 1979].

The Cultural Heritage disappears at a rate higher than we are able, not only, to restore but also to document: human and natural factors, negligence or worst, deliberate demolitions put in danger the collective Architectural Heritage (AH). According to CIPA statements, the recording is important and has to follow some guidelines. The Architectural and Urban Heritage data have to be historically related, critically assessed and analyzed, before to be organized according to a thematic structure and become available for further uses. This paper shows the experiences developed by the Laboratory of Computer Graphics applied to Architecture and Design (LCAD), at the Architecture School of the Federal University of Bahia (FAUFBA), Brazil, in cooperation with the Università Politecnica delle Marche (UNIVPM, DICEA Department), Italy, in documenting architectural heritage. The research set up now has been carried out in the historical sites of Bahia, as Pelourinho neighborhood, a World Heritage by UNESCO. Other historical sites are in the plan of this survey, like the cities of Lençóis and Mucugê in Chapada Diamantina region. The aim is to build a technological platform based on low cost digital technologies and open source tools, such as Panoramic Spherical Photogrammetry, Spatial Database, Geographic Information Systems, Three-dimensional Geometric Modeling, CAD technology, for the collection, validation and dissemination of AH.

Health-care companies around the world face an unprecedented challenge of rising health-care costs, increasing life expectancy and escalating demand. Although national health-care budgets have increased (as a percentage of gross domestic product) health care continues to impart significant upward pressure on national expenditure, particularly in the UK ( Licchetta and Stelmach, 2016 ). Additionally a substantial funding gap will continue to grow ( Gainsbury, 2016 ). In response to this challenge a 'value' based strategy has gained momentum over the last two decades. Several pioneers of this approach (Sir Muir Gray at Oxford University, Professor Michael Porter at Harvard University and Professor Elizabeth Teisberg at Dell Medical School) emphasize the importance of organizations focusing on 'value'. Porter and Teisberg (2006) highlight the 'value equation' as obtaining the very best patient outcomes for each unit of currency spent. Gray expands on this model, describing three types of value: allocative, technical and personal ( Gray, 2011 ). Although some global health-care organizations have embraced the value-based agenda to transform acute care facilities, mental health providers have been slow to consider the benefits of this approach. This article gives a broad overview of implementing a value-based model in mental health care, the significant development resources needed, organizational issues, and finally concludes with the benefits and a vision of value-based mental health care for the future.

rainfall intensity and an increasing trend of wet days and temperatures) does not show favourable conditions for the increase of the annual number of damaging floods, its trend is increasing. The role of anthropogenic modifications and the mismanagement of risk-prone areas should be considered to justify the increasing occurrences of floods. A validation of this hypothesis comes from the study of land use modifications, carried out comparing different temporal levels of land use (from 1959 to 2006). The analysis shows, starting from 1959 to 2006, a significant increase in urban areas (of about 50%) on the entire regional territory. The municipality of Bari, the regional main town, has undergone a remarkable development of its urban areas, from 12.45 Km2 in 1959 to 58.82 Km2 in 2006. The consequent increased vulnerability of this area has been highlighted during the recent flood event occurred in 2005, which caused six casualties, numerous injuries and damages to roads, buildings, industries, agriculture, livestock and services. More details on previous results of this research activity were recently published (Polemio, 2010; Polemio and Lonigro, 2012). References Polemio M.

A full 2D approach integrates the hydrological and hydraulic models, in order to account first for the dynamic of catchment response to rainfall and activation of the streams, and then for the hydraulic behaviour of the streams. This analysis entails the simulation of extreme events corresponding to low, medium and high return periods, in order to identify which event presumably activate the ephemeral streams.

The Southern California Earthquake Center (SCEC) has a science program in developing an integrated cyberfacility - PetaSHA - for executing physics-based seismic hazard analysis (SHA) computations. The NSF has awarded PetaSHA 15 million allocation service units this year on the fastest supercomputers available within the NSF TeraGrid. However, one size does not fit all, a range of systems are needed to support this effort at different stages of the simulations. Enabling PetaSHA simulations on those TeraGrid architectures to solve both dynamic rupture and seismic wave propagation have been a challenge from both hardware and software levels. This is an adaptation procedure to meet specific requirements of each architecture. It is important to determine how fundamental system attributes affect application performance. We present an adaptive approach in our PetaSHA application that enables the simultaneous optimization of both computation and communication at run-time using flexible settings. These techniques optimize initialization, source/media partition and MPI-IO output in different ways to achieve optimal performance on the target machines. The resulting code is a factor of four faster than the orignial version. New MPI-I/O capabilities have been added for the accurate Staggered-Grid Split-Node (SGSN) method for dynamic rupture propagation in the velocity-stress staggered-grid finite difference scheme (Dalguer and Day, JGR, 2007), We use execution workflow across TeraGrid sites for managing the resulting data volumes. Our lessons learned indicate that minimizing time to solution is most critical, in particular when scheduling large scale simulations across supercomputer sites. The TeraShake platform has been ported to multiple architectures including TACC Dell lonestar and Abe, Cray XT3 Bigben and Blue Gene/L. Parallel efficiency of 96% with the PetaSHA application Olsen-AWM has been demonstrated on 40,960 Blue Gene/L processors at IBM TJ Watson Center. Notable

The aim of this study is monitoring, mapping and forecast of pollen distribution for the city of Rome using in-situ measurements of 10 species of common allergenic pollens and measurements of PM10. The production of daily concentration maps, associated to a mobile phone app, are innovative compared to existing dedicated services to people who suffer from respiratory allergies. The dispersal pollen is one of the most well-known causes of allergic disease that is manifested by disorders of the respiratory functions. Allergies are the third leading cause of chronic disease and it is estimated that tens millions of people in Italy suffer from it. Recent works reveal that during the last few years there was a progressive increase of affected subjects, especially in urban areas. This situation may depend: on the ability to transport of pollutants, on the ability to react between pollutants and pollen and from a combination of other irritants, existing in densely populated and polluted urban areas. The methodology used to produce maps is based on in-situ measurements time series relative to 2012, obtained from networks of air quality and pollen stations in the metropolitan area of Rome. The monitoring station aerobiological of University of Rome "Tor Vergata" is located at the Department of Biology. The instrument used to pollen monitoring is a volumetric sampler type Hirst (Hirst 1952), Model 2000 VPPS Lanzoni; the data acquisition is carried out as reported in Standard UNI 11008:2004 - "Qualità dell'aria - Metodo di campionamento e conteggio dei granuli pollinici e delle spore fungine aerodisperse" - the protocol that describes the procedure for measuring of the concentration of pollen grains and fungal spores dispersed into the atmosphere, and reported in the "Manuale di gestione e qualità della R.I.M.A" (Travaglini et. al. 2009). All 10 allergenic pollen are monitored since 1996. At Tor Vergata university is also operating a meteorological station (SP2000, CAE

Over the past 40 years, Lunar Laser Ranging (LLR, developed by the Univ. of Maryland (PI) and INFN-LNF (Co-PI)) to the Apollo Cube Corner Retroreflector (CCR) arrays have supplied almost all the significant tests of General Relativity (Currie et al., 2009 [12]). LLR can evaluate the PPN (Post Newtonian Parameters), addressing this way both the possible changes in the gravitational constant and the self-energy properties of the gravitational field. In addition, the LLR has provided significant information on the composition and origin of the Moon. This is the only Apollo experiment that is still in operation. Initially the Apollo LLR arrays contributed a negligible fraction of the ranging error budget. Over the decades, the ranging capabilities of the ground stations have improved by more than two orders of magnitude. Now, because of the lunar librations, the existing Apollo retroreflector arrays contribute a significant fraction of the limiting errors in the range measurements. We built a new experimental apparatus (the ‘Satellite/Lunar Laser Ranging Characterization Facility', SCF) and created a new test procedure (the SCF-Test) to characterize and model the detailed thermal behavior and the optical performance of cube corner laser retroreflectors in space for industrial and scientific applications (Dell'Agnello et al., 2011 [13]). Our key experimental innovation is the concurrent measurement and modeling of the optical Far Field Diffraction Pattern (FFDP) and the temperature distribution of the SLR retroreflector payload under thermal conditions produced with a close-match solar simulator. The apparatus includes infrared cameras for non-invasive thermometry, thermal control and real-time movement of the payload to experimentally simulate satellite orientation on orbit with respect to both solar illumination and laser interrogation beams. These unique capabilities provide experimental validation of the space segment for SLR and Lunar Laser Ranging (LLR). The

Soils in volcanic and hydrothermal areas are affected by anomalously high concentrations of gases released from the deep reservoirs, which consists of both inorganic (mainly CO2 and H2S) and organic (volatile organic compounds; VOCs) species. VOCs in volcanic and hydrothermal fluids are mainly composed of saturated and unsaturated hydrocarbons (alkanes, aromatics, alkenes, and cyclics), with variable concentrations of O- and S-bearing compounds and halocarbons, depending on the physicochemical conditions at depth. VOCs in interstitial soil gases and fumarolic emissions from four volcanic and hydrothermal systems in the Mediterranean area (Solfatara Crater, Poggio dell'Olivo and Cava dei Selci, in Italy, and Nisyros Island, in Greece) evidenced clear compositional differences, suggesting that their behavior is strongly affected by secondary processes occurring at shallow depths and likely controlled by microbial activity. Long-chain saturated hydrocarbons were significantly depleted in interstitial soil gases with respect to those from fumarolic discharges, whereas enrichments in O-bearing compounds (e.g. aldehydes, ketones), DMSO2 and cyclics were commonly observed. Benzene was recalcitrant to degradation processes, whereas methylated aromatics were relatively instable. The chemical and isotopic (δ13C in CO2 and CH4) composition of soil gases collected along vertical profiles down to 50 cm depth at both Solfatara Crater and Poggio dell'Olivo (Italy) showed evidences of relevant oxidation processes in the soil, confirming that microbial activity likely plays a major role in modifying the composition of deep-derived VOCs. Despite their harsh conditions, being typically characterized by high temperatures, low pH, and high toxic gases and metal contents, the variety of habitats characterizing volcanic and hydrothermal environments offers ideal biomes to extremophilic microbes, whose metabolic activity can consume and/or produce VOCs. In the Solfatara Crater, microbial

Whether a computer is simulating the aging and performance of a nuclear weapon, the folding of a protein, or the probability of rainfall over a particular mountain range, the necessary calculations can be enormous. Our computers help researchers answer these and other complex problems, and each new generation of system hardware and software widens the realm of possibilities. Building on Livermore's historical excellence and leadership in high-performance computing, Computation added more than 331 trillion floating-point operations per second (teraFLOPS) of power to LLNL's computer room floors in 2008. In addition, Livermore's next big supercomputer, Sequoia, advanced ever closer to itsmore » 2011-2012 delivery date, as architecture plans and the procurement contract were finalized. Hyperion, an advanced technology cluster test bed that teams Livermore with 10 industry leaders, made a big splash when it was announced during Michael Dell's keynote speech at the 2008 Supercomputing Conference. The Wall Street Journal touted Hyperion as a 'bright spot amid turmoil' in the computer industry. Computation continues to measure and improve the costs of operating LLNL's high-performance computing systems by moving hardware support in-house, by measuring causes of outages to apply resources asymmetrically, and by automating most of the account and access authorization and management processes. These improvements enable more dollars to go toward fielding the best supercomputers for science, while operating them at less cost and greater responsiveness to the customers.« less

Studies in many species indicate that variation of spermatozoan head morphology is a sensitive biomarker for abnormal chromatin structure and resultant clinical fertility. This preliminary study evaluated spermatozoan head morphometry in different dog breeds and assessed whether morphometric parameters could reflect spermatozoan DNA fragmentation in dogs. Spermatozoan morphometry and DNA quality (measured by TUNEL flow cytometry) were assessed in semen from 11 dogs of three Italian breeds (Cirneco dell'Etna, Piccolo Levriero Italiano and Segugio Maremmano). Morphometric data showed that Segugio dogs had significantly larger (33·67%) spermatozoa and that Piccolo Levrieros had a higher incidence of long (46·75%) and elliptical spermatozoan heads (11·5%) when compared with the samples from other breeds. Moreover, the predominance of elliptical spermatozoa in one dog (23%) was significantly related to the percentage of spermatozoa with fragmented DNA (12·6%), whereas in another dog, where no more than 1% of spermatozoa was elliptical, only 0·36% of spermatozoa had damaged DNA. It is noteworthy that the breeding record of the former dog in the previous 12 months showed poor fertility and fecundity. These data suggest that spermatozoan head morphometry could be breed related and that there is a significant correlation between DNA fragmentation and elliptical spermatozoa in individual animals. This finding, albeit limited in our study to a single case, is possibly related to clinical infertility. © 2010 British Small Animal Veterinary Association.

Complex regional pain syndrome (CRPS) type I may occur as complication after any type of surgery for basal joint arthritis of the thumb. We investigated prospectively in an ongoing study our results after a fully standardized treatment with a total joint prosthesis under vitamin C prophylaxis.Patients with trapeziometacarpal arthritis stage II or III according to Dell, and no benefit from conservative treatment, were selected to undergo joint replacement with a semi-constrained hydroxyapatite coated prosthesis.First web opening and visual analogue scale (VAS) scores for pain, activities of daily living (ADL) and satisfaction were taken pre and postoperatively. Vitamin C 500 mg daily was started two days prior to surgery during 50 days as prevention for CRPS. Post-operative treatment was functional.We performed 40 implantations for trapeziometacarpal arthritis in 34 patients (mean age 60.8 years; 27 females, 7 males) with a mean follow-up of 44 months. Operations were performed in day care under regional (or general) anesthesia.First web opening increased with 15.4 degrees and there was a significant improvement for pain, ADL and satisfaction as well (p = 0.000). Patient satisfaction was strongly associated with the amount of pain reduction. According to the Veldman and IASP criteria, there were no cases of CRPS.The overall complication rate for this procedure is high. Literature reports 5 cases of CRPS after 38 operations with the same implant (13%). We advise vitamin C as prophylaxis against CRPS in trapeziometacarpal joint replacement.

Completing the gaps in Kilauea's Father's Day InSAR displacement signature with ScanSAR

Currently there are gaps in the known displacement signature obtained with InSAR at Kilauea between 2002 and 2009. InSAR data can be richer than GPS because of denser spatial cover. However, to better model rapidly varying and non-steady geophysical events InSAR is limited because of its less dense time observations of the area under study. The ScanSAR mode currently available in several satellites mitigates this effect because the satellite may illuminate a given area more than once within an orbit cycle. The Kilauea displacement graph below from Instituto per Il Rilevamento Electromagnetico dell'Ambiente (IREA) is a cut in space of the displacement signature obtained from a time series of several stripmap-to-stripmap interferograms. It shows that critical information is missing, especially between 2006 and 2007. The displacement is expected to be non-linear judging from the 2007-2008 displacement signature, thus simple interpolation would not suffice. The gap can be filled by incorporating Envisat stripmap-to-ScanSAR interferograms available during that time period. We propose leveraging JPL's new ROI-PAC ScanSAR module to create stripmap-to-ScanSAR interferograms. The new interferograms will be added to the stripmap ones in order to extend the existing stripmap time series generated by using the Small BAseline Subset (SBAS) technique. At AGU we will present denser graphs that better capture Kilauea's displacement between 2003 and 2009.

Malgré l'importance de leurs effets secondaires sur la femme enceinte et le fœtus, les anti-inflammatoires non stéroïdiens (AINS) continuent à être largement utilisés par les femmes enceintes. Leur rapport bénéfice-risque n'est pas toujours bien évalué en pratique courante. L'objectif de ce travail est d’évaluer l'usage des AINS chez la femme enceinte, de discuter les risques potentiels encourus aussi bien par la mère que par le fœtus, et enfin d'en tirer des recommandations éventuelles à la femme enceinte. Du 22 août au 11 septembre 2012, une enquête a été menée auprès de 145 femmes enceintes suivies en consultation prénatale à l'Hôpital Sendwe. Un formulaire reprenant les informations sur les AINS consommés a été remis à chacune d'elle. Les résultats montrent que 75% des femmes interrogées reconnaissent avoir consommé des AINS surtout en automédication et principalement pendant les deux derniers trimestres de la grossesse pour soulager des douleurs d'origines diverses. Cette étude montre que des efforts restent encore à déployer à Lubumbashi afin de combattre l'utilisation des AINS surtout en automédication chez la femme enceinte. PMID:25419270

A prospective, randomized, blinded, controlled experimental trial was performed in pigs to compare the rates of reepithelialization of 126 full-thickness cutaneous 4-mm punches treated with an octyl-cyanoacrylate spray, silver sulfadiazine, or a dry gauze (controls). Full thickness biopsies were taken 7, 14, or 30 days later for histopathological evaluation of hematoxylin and eosin stained tissue sections by a dermatopathologist. The primary outcome measure was the proportion of wounds completely re-epithelialized at days 7 and 14. Secondary outcomes were the rates of infection, foreign body reactions, and the depth of any resulting cutaneous dells measured with a micrometer. Between-group comparisons were performed with ANOVA or Chi-square tests. Octyl-cyanoacrylate treated wounds re-epithelialized more slowly, as fewer wounds treated with octyl-cyanoacrylate were re-epithelialized at day 7 in comparison with silver sulfadiazine or control wounds (50% vs. 90% vs. 100%, p < 0.001). There were no infections or foreign body type reactions. Amounts of granulation tissue were similar among groups. Octyl-cyanoacrylate wounds were more depressed than silver sulfadiazine wounds at days 7 and 14 yet had similar histopathological characteristics at day 30. We conclude that treatment of small, full thickness cutaneous wounds with octyl-cyanoacrylate results in delayed re-epithelialization and dermal repair in comparison with silver sulfadiazine, yet it does not result in any foreign body-type reaction. However, by 30 days, histopathological wound characteristics were similar in all groups.

About 1300 obsidian artefacts coming from various archaeological sites of Sicily were analyzed by using the BSC-XRF (Beam Stability Controlled - X-ray Fluorescence) and PIXE-alpha (Particle Induced X-ray Emission, using low energy alpha particles) portable spectrometers developed at the Landis laboratory at the LNS-INF and IBAM-CNR in Catania (Italy). The portable BSC-XRF system allows the non-destructive analysis of the Rb, Sr, Y, Zr and Nb trace concentrations, which are considered to be characteristic of the obsidian samples and consequently are indicative of the provenance quarries. Quantitative data on Rb, Sr, Y, Zr, Nb trace element concentrations where deduced through the use of a method that makes use of a multi parameter linear regression, previously The portable PIXE-alpha spectrometer allows the quantitative determination of the matrix major elements, from Na to Zn. In the present work the two instrumental devices are presented. The data are from: Milena (Cl), Ustica (Pa), Rocchicella (Ct), Poggio dell'Acquila (Ct), San Marco (Ct), Villaggio del Petraro* (Sr) and Licodia Eubea* (Ct). Results on compositional data for trace elements and major elements allowed to identify Lipari and Pantelleria islands as the only two sources of the analysed samples. Analyses carried out on vitreous artefact found in Rocchicella, showed for the first time that the Palagonite was used as row material. *Preliminary data.

Acrylamide forms during cooking and processing predominately from the reaction of free asparagine and reducing sugars in the Maillard reaction. The identification of low free asparagine and reducing sugar varieties of crops is therefore an important target. In this study, nine varieties of potato (French fry varieties Maris Piper (from two suppliers), Pentland Dell, King Edward, Daisy, and Markies; and chipping varieties Lady Claire, Lady Rosetta, Saturna, and Hermes) grown in the United Kingdom in 2009 were analyzed at monthly intervals through storage from November 2009 to July 2010. Acrylamide formation was measured in heated flour and chips fried in oil. Analysis of variance revealed significant interactions between varieties nested within type (French fry and chipping) and storage time for most free amino acids, glucose, fructose, and acrylamide formation. Acrylamide formed in chips correlated significantly with acrylamide formed in flour and with chip color. There were significant correlations between glucose or total reducing sugar concentration and acrylamide formation in both variety types, but with fructose the correlation was much stronger for chipping than for French fry varieties. Conversely, there were significant correlations with acrylamide formation for both total free amino acid and free asparagine concentration in the French fry but not chipping varieties. The study showed the potential of variety selection for preventing unacceptable levels of acrylamide formation in potato products and the variety-dependent effect of long-term storage on acrylamide risk. It also highlighted the complex relationship between precursor concentration and acrylamide risk in potatoes.

Facilitation and interference in naming: A consequence of the same learning process?

PubMed

Hughes, Julie W; Schnur, Tatiana T

2017-08-01

Our success with naming depends on what we have named previously, a phenomenon thought to reflect learning processes. Repeatedly producing the same name facilitates language production (i.e., repetition priming), whereas producing semantically related names hinders subsequent performance (i.e., semantic interference). Semantic interference is found whether naming categorically related items once (continuous naming) or multiple times (blocked cyclic naming). A computational model suggests that the same learning mechanism responsible for facilitation in repetition creates semantic interference in categorical naming (Oppenheim, Dell, & Schwartz, 2010). Accordingly, we tested the predictions that variability in semantic interference is correlated across categorical naming tasks and is caused by learning, as measured by two repetition priming tasks (picture-picture repetition priming, Exp. 1; definition-picture repetition priming, Exp. 2, e.g., Wheeldon & Monsell, 1992). In Experiment 1 (77 subjects) semantic interference and repetition priming effects were robust, but the results revealed no relationship between semantic interference effects across contexts. Critically, learning (picture-picture repetition priming) did not predict semantic interference effects in either task. We replicated these results in Experiment 2 (81 subjects), finding no relationship between semantic interference effects across tasks or between semantic interference effects and learning (definition-picture repetition priming). We conclude that the changes underlying facilitatory and interfering effects inherent to lexical access are the result of distinct learning processes where multiple mechanisms contribute to semantic interference in naming.

The focus and funding of US healthcare is evolving from volume to value-based, and healthcare leaders, managers, payers, and researchers are increasingly focusing on managing populations of patients. Simultaneously, there is increasing interest in getting "upstream" from disease management to promote health and prevent disease. Hence, the term "population health" has both clinical and community-based connotations relevant to the tripartite mission of US medical schools. To seek broad input for the strategic development of the Department of Population Health in a new medical school at a tier 1 research university. Focus groups with facilitated consensus development. Eighty-one persons representing the Dell Medical School and other schools at the University of Texas at Austin, city/county government, community nonprofit organizations, and faculty from other local university schools along with selected national academic leaders. Focus groups with subsequent consensus development of emphases identified premeeting by participants by e-mail exchanges. The resulting departmental strategic plan included scope of work, desired characteristics of leaders, and early impact activities in seven areas of interest: community engagement and health equity, primary care and value-based health, occupational and environment medicine, medical education, health services and community-based research, health informatics and data analysis, and global health. Medical schools should have a primary focus in population, most effectively at the departmental level. Engaging relevant academic and community stakeholders is an effective model for developing this emerging discipline in US medical schools.

Preliminary study of favorability for uranium resources in Juab County, Utah

The best potential for large, low-grade uranium deposits in Juab County is in the hydrothermally altered vitric tuffs of Pliocene age. The lateral extent of the altered tuffs may be determined by subsurface studies around the perimeter of the volcanic centers in the Thomas Range and the Honeycomb Hills. Because the ring-fracture zone associated with collapse of the Thomas caldera was a major control for hydrothermal uranium deposits, delineation of the northern and eastern positions of the ring-fracture zone is critical in defining favorable areas for uranium deposits. A small, medium-grade ore deposit in tuffaceous sand of Pliocene age atmore » the Yellow Chief mine in Dugway Dell is unique in origin, and the probability of discovering another deposit of this type is low. A deposit of this type may be present under alluvial cover in the northwestern Drum Mountains along the southern extension of the ring-fracture zone of the Thomas caldera. Festoonlike iron oxide structures and uranium deposition within permeable sandstone horizons indicate that the Yellow Chief deposit was formed by recent ground-water circulation. Granitic intrusive rocks in the Deep Creek Range and in Desert Mountain contain isolated epigenetic vein-type deposits. These rocks could be a source of arkosic sediments buried in adjacent valleys. The Pleistocene lacustrine sediments and playa lake brines may contain concentrations of uranium leached from uranium-rich rocks.« less

A combination of bioactive food ingredients (capsaicinoids, epigallocatechin gallate, piperin, and l-carnitine, CBFI) may promote satiety and thermogenesis. The study was conducted in order to assess whether there is any effect on satiety, resting energy expenditure (REE), respiratory quotient, glucagon-like peptide-1 (GLP-1), free fatty acids (FFA) and glycerol release, following a standardized mixed meal with or without single consumption of a CBFI. An 8-week randomized double-blind placebo-controlled trial. Dietetic and Metabolic Unit, Azienda di Servizi alla Persona, University of Pavia and "Villa delle Querce" Clinical Rehabilitation Institute, Rome, Italy. Thirty-seven overweight adults (body mass index [BMI]: 25-35). Nineteen overweight subjects were included in the supplemented group (14 women, 5 men; age 46.4 ± 6.4; BMI: 30.5 ± 3.3) and 18 in the placebo group (13 women, 5 men; age 40.8 ± 11.5; BMI: 30.1 ± 2.6). Satiety was assessed using 100-mm visual analogue scales (VAS) and the area under the curve was calculated. All measured parameters increased significantly in comparison with baseline in response to meal, both with CBFI and with placebo. However, throughout the study day, the supplemented group experienced a significantly greater increase than the placebo group in their sensation of satiety following acute administration of the supplement. CBFI may therefore be of great value in the treatment of overweight patients by increasing satiety and stimulating thermogenesis.

The following is an interim annual report. Dr. Smith is currently on an extended TDY to the Istituto di Fisica dello Spazio Interplanetario (IFSI) at the Consilio Nazionale delle Richerche (CNR) in Rome, Italy, where he has been working on a related NASA grant in support of analysis of Infrared Space Observatory (ISO) data on star formation in Ultra Luminous Infrared Galaxies and our galaxy. Work emphasizes development of metal mesh grids for use in spacecraft, and the design and fabrication of test elements by the Naval Research Laboratory, Washington D.C. Work has progressed well, but slowly, on that program due to the departure of a key engineer. NASA has been advised of the delay, and granted a no-cost extension, whereby SAO has authorized a delay in the final report from NRL. Nevertheless NRL has continued to make progress. Two papers have been submitted to refereed journals related to this program, and a new design for mesh operating in the 20-40 micron region has been developed. Meetings continue through the summer on these items. A new technical scientist has been made a job offer and hopefully will be on board NRL shortly, although most of the present grant work is already completed. A more complete report, with copies of the submitted papers, designs, and other measures of progress, will be submitted to NASA in September when Dr. Smith returns from his current TDY.

Highly efficient generation of glutamatergic/cholinergic NT2-derived postmitotic human neurons by short-term treatment with the nucleoside analogue cytosine β-D-arabinofuranoside.

The human NTERA2/D1 (NT2) cells generate postmitotic neurons (NT2N cells) upon retinoic acid (RA) treatment and are functionally integrated in the host tissue following grafting into the rodent and human brain, thus representing a promising source for neuronal replacement therapy. Yet the major limitations of this model are the lengthy differentiation procedure and its low efficiency, although recent studies suggest that the differentiation process can be shortened to less than 1 week using nucleoside analogues. To explore whether short-term exposure of NT2 cells to the nucleoside analogue cytosine β-d-arabinofuranoside (AraC) could be a suitable method to efficiently generate mature neurons, we conducted a neurochemical and morphometric characterization of AraC-differentiated NT2N (AraC/NT2N) neurons and improved the differentiation efficiency by modifying the cell culture schedule. Moreover, we analyzed the neurotransmitter phenotypes of AraC/NT2N neurons. Cultures obtained by treatment with AraC were highly enriched in postmitotic neurons and essentially composed of dual glutamatergic/cholinergic neurons, which contrasts with the preferential GABAergic phenotype that we found after RA differentiation. Taken together, our results further reinforce the notion NT2 cells are a versatile source of neuronal phenotypes and provide a new encouraging platform for studying mechanisms of neuronal differentiation and for exploring neuronal replacement strategies.

Here, we present measurements ofmore » $E$-mode polarization and temperature-$E$$-mode correlation in the cosmic microwave background (CMB) using data from the first season of observations with SPTpol, the polarization-sensitive receiver currently installed on the South Pole Telescope (SPT). The observations used in this work cover 100~\\sqdeg\\ of sky with arcminute resolution at $$150\\,$GHz. We also report the $E$-mode angular auto-power spectrum ($EE$) and the temperature-$E$-mode angular cross-power spectrum ($TE$) over the multipole range $$500 < \\ell \\leq5000$$. These power spectra improve on previous measurements in the high-$$\\ell$$ (small-scale) regime. We fit the combination of the SPTpol power spectra, data from \\planck\\, and previous SPT measurements with a six-parameter \\LCDM cosmological model. Furthermore, we find that the best-fit parameters are consistent with previous results. The improvement in high-$$\\ell$$ sensitivity over previous measurements leads to a significant improvement in the limit on polarized point-source power: after masking sources brighter than 50\\,mJy in unpolarized flux at 150\\,GHz, we find a 95\\% confidence upper limit on unclustered point-source power in the $EE$ spectrum of $$D_\\ell = \\ell (\\ell+1) C_\\ell / 2 \\pi < 0.40 \\ \\mu{\\mbox{K}}^2$$ at $$\\ell=3000$$, indicating that future $EE$ measurements will not be limited by power from unclustered point sources in the multipole range $$\\ell < 3600$$, and possibly much higher in $$\\ell.$$« less

Fringe pattern demodulation using the one-dimensional continuous wavelet transform: field-programmable gate array implementation.

PubMed

Abid, Abdulbasit

2013-03-01

This paper presents a thorough discussion of the proposed field-programmable gate array (FPGA) implementation for fringe pattern demodulation using the one-dimensional continuous wavelet transform (1D-CWT) algorithm. This algorithm is also known as wavelet transform profilometry. Initially, the 1D-CWT is programmed using the C programming language and compiled into VHDL using the ImpulseC tool. This VHDL code is implemented on the Altera Cyclone IV GX EP4CGX150DF31C7 FPGA. A fringe pattern image with a size of 512×512 pixels is presented to the FPGA, which processes the image using the 1D-CWT algorithm. The FPGA requires approximately 100 ms to process the image and produce a wrapped phase map. For performance comparison purposes, the 1D-CWT algorithm is programmed using the C language. The C code is then compiled using the Intel compiler version 13.0. The compiled code is run on a Dell Precision state-of-the-art workstation. The time required to process the fringe pattern image is approximately 1 s. In order to further reduce the execution time, the 1D-CWT is reprogramed using Intel Integrated Primitive Performance (IPP) Library Version 7.1. The execution time was reduced to approximately 650 ms. This confirms that at least sixfold speedup was gained using FPGA implementation over a state-of-the-art workstation that executes heavily optimized implementation of the 1D-CWT algorithm.

The data included basic information related to the therapy prescribed, its duration, a judgement on the efficacy of symptoms control and the main problems encountered with the children and their families. 237 cases were reported (mean age 4.6 year, range 2 months-13 years). 80% of children were monitored by the pediatrician; 47% had allergic reactions. The main drug used for profilaxis is ketotifen, a compound without documented efficacy; the main route for drug administration (especially during acute attacks) is by mouth, instead of by aerosol, evidencing problems in the health education on practical skills. In fact the main problems encountered by doctors are related to the communication with patients and families. This survey represents also a research model for involving health care providers and easily and quickly obtaining a useful, methodologically sound and interesting picture of everyday practice.

The work done for Stardust samples is important to understand the similarities and differences among comets. In fact, the results of this study are relevant also for the ROSETTA mission that encountered the Jupiter-Family (J-F) comet 67P/Churyumov-Gerasimenko in August, 2014. At the time this mission was launched, our ideas of comet dust were biased by the findings of the Halley missions. The Stardust mission showed an unexpected richness of dust that originated from the inner solar system. Rosetta is confirming these results but also adding information, in particular on the presence of a primitive and unprocessed dust component \\cite{Fulle15}.

Reconstructions of the atmospheric content of black carbon, heavy metals and mineral dust covering millennial time scales are rare, particularly in the European region. Evaluating the human impact on the environment through mining and industrial activities, road traffic, biomass and coal burning, and the naturally emitted aerosols atmospheric load, is important to know the degree of contaminations and the quality of melting water, the radiative effect on the glacier's radiative balance, the atmospheric aerosols' climatic impacts and the recent decades pollutions emissions policies' efficiencies. Four ice cores were drilled in 2011 from the "Alto dell'Ortles" (3859 m), the highest glacier of the Mt. Ortles massif (South Tirol, Italy). Three 74 m long ice cores were dated by mean of 210Pb, tritium, beta emissions and 14C analyses following also the new dating technique based on filtering the ice for extracting the carbonaceous component of the deposited aerosols. The depth-age curve was obtained by using a Monte Carlo based empirical fitting model (COPRA). The basal ice of core#2 and #3 was dated back to about 7000 years b.p., whereas that of core#1, about one meter shorter, to 3000 years before present. Below the firn-ice transition, at a depth of about 24 m, the borehole temperature revealed the presence of well-preserved cold ice (Gabrielli et al, 2012). The O and H stable isotopes profiles describe well the atmospheric warming as well as the low temperatures recorded during the Little Ice Age (LIA). The proximity of the "Alto dell'Ortles" to densely industrialized areas (Po Valley) makes these ice cores specifically suited for reconstructing the anthropogenic impacts in the Eastern European Alpine region over the last 3 millennia. The ice core#1 was analyzed with a "Continuous Flow Analysis" system (CFA). The separation between internal and external parts of the core prevents any kind of contamination. The core was melted at about 2.5 cm min-1 and simultaneous

Early Levallois and the beginning of the Middle Paleolithic in central Italy.

In the second half of the 19th century Pleistocene faunas were discovered in two sites, Sedia del Diavolo and Monte delle Gioie, contained in deposits of the Aniene River in the area of Rome (Latium, Italy). Fieldwork by A.C. Blanc in the late 1930's proved the association of fauna and lithic industry within fluvial deposits interbedded with volcanoclastic layers. A human femoral diaphysis and a metatarsal were later identified in the faunal assemblage from Sedia del Diavolo and evaluated as Neandertal. The lithic assemblages from these two sites were the basis of the definition of the Protopontinian by M. Taschini, which she viewed as a late Middle Pleistocene industry very similar to the later, Upper Pleistocene Pontinian industries, thought to be characteristic of the Latium Mousterian. The chronostratigraphic framework of the Aniene river deposits has been recently updated and the lithic assemblages from these two sites are now confidently dated between 295 and 290 ka, close to the transition from MIS 9 to MIS 8. They fit chronologically between the industries of layers m and d from Torre in Pietra, a site 26 km northwest of Rome. The presence of the Levallois debitage is indisputable yet it occurs within an original technical context, different from what is known in other early occurrences of the Levallois. The date confirms the proposed chronology for the early Levallois in Europe. More importantly these two assemblages demonstrate that this technology can emerge in more diversified contexts than usually described. This suggests that its dispersal in Europe may have been rapid.

This revision of the buccinulid genera Pareuthria Strebel, 1905, Glypteuthria Strebel, 1905 and Meteuthria Thiele, 1912 includes all the reported nominal species and type specimens. A total of 13 valid species included in six genera are described and illustrated. All but one -P. fuscata- live in shallow waters around the Magellanic region and even reach lower latitudes including deeper waters off the Buenos Aires province. The genus Pareuthria includes P. fuscata (Bruguière, 1789), P. atrata (E. A. Smith, 1881) for which a lectotype is designated, and P. venustula Powell, 1951. P. fuscata is also confirmed to occur in New Zealand waters. Glypteuthria Strebel, 1905 includes only the type species G. meridionalis (E.A. Smith, 1881). Two species are included in the genus Meteuthria Thiele, 1912, the type species M. martensi (Strebel, 1905), for which a lectotype is designated, and M. batialis n. sp., which is described herein based on specimens from deep water off Buenos Aires province. Three new genera are described: Falsimacme n. gen. to include only the type species F. kobelti (Strebel, 1905) (formerly in the genus Meteuthria); Argeneuthria n. gen. to include A. cerealis (Rochebrune & Mabille, 1885), A. paessleri (Strebel, 1905), A. euthrioides (Melvill & Standen, 1898), A. philippii (Strebel, 1905) and A. varicosa new species; and Microdeuthria n. gen. to include only M. michaelseni (Strebel, 1905). In addition, "Anomacme" multituberculata Castellanos, Rolán & Bartolotta, 1987 included by Dell (1990) in Meteuthria is excluded from the latter genus based on the morphology of the radula.

Profit pools: a fresh look at strategy.

Gadiesh, O; Gilbert, J L

1998-01-01

In charting strategy, many managers focus on revenue growth, assuming that profits will follow. But that approach is dangerous: today's deep revenue pool may become tomorrow's dry hole. To create strategies that result in profitable growth, managers need to look beyond revenues to see the shape of their industry's profit pool. The authors define an industry's profit pool as the total profits earned at all points along the industry's value chain. Although the concept is simple, the structure of a profit pool is usually quite complex. The pool will be deeper in some segments of the value chain than in others, and depths will vary within an individual segment as well. Segment profitability may, for example, vary widely by customer group, product category, geographic market, and distribution channel. Moreover, the pattern of profit concentration in an industry will often be very different from the pattern of revenue concentration. The authors describe how successful companies have gained competitive advantage by developing sophisticated profit-pool strategies. They explain how U-Haul identified new sources of profit in the consumer-truck-rental industry; how Merck reached beyond its traditional value-chain role to protect its profits in the pharmaceuticals industry; how Dell rebounded from a misguided channel decision by refocusing on its traditional source of profit; and how Anheuser-Busch made a series of astute product, pricing, and operating decisions to dominate the beer industry's profit pool. The companies with the best understanding of their industry's profit pool, the authors argue, will be in the best position to thrive over the long term.

The article aims to study mother-child and father-child interactions with 24-month-old children during feeding, considering the possible influence of time spent by the parent with the child, the infantile temperament, and the parental psychological profile. The families were recruited from 12 preschools in Italy (N = 77 families). Through an observation of the feeding [Scala di Valutazione dell'Interazione Alimentare (SVIA - Feeding Scale; I. Chatoor et al., ; L. Lucarelli et al., )], self-reporting [Symptom Checklist-90-Revised (SCL-90-R; L.R. Derogatis, ), and report-form questionnaires [Italian Questionnaires on Temperament (QUIT; G. Axia, )], and information provided by the parents about the amount of time spent with their children, results showed that the overall quality of father-child interactions during feeding is lower than that of mother-child interactions. Fathers showed higher psychological symptoms than did mothers. No associations were found between the fathers' psychopathological risk and the quality of interactions with their children during feeding. Mothers' psychopathological risks predicted less contingent exchanges interactions with their children during feeding. Children's temperaments significantly influence mother-child interactions, but no association exists between maternal involvement and the quality of interactions with their children. Paternal involvement predicts a better quality of father-infant interactions when associated with a child's higher scores on Social Orientation. The quality of parents' interactions with their children during feeding are impacted by different issues originating from the parent's psychological profile, the degree of involvement, and from the child's temperament. © 2014 Michigan Association for Infant Mental Health.

Breaking the trade-off between efficiency and service.

PubMed

Frei, Frances X

2006-11-01

For manufacturers, customers are the open wallets at the end of the supply chain. But for most service businesses, they are key inputs to the production process. Customers introduce tremendous variability to that process, but they also complain about any lack of consistency and don't care about the company's profit agenda. Managing customer-introduced variability, the author argues, is a central challenge for service companies. The first step is to diagnose which type of variability is causing mischief: Customers may arrive at different times, request different kinds of service, possess different capabilities, make varying degrees of effort, and have different personal preferences. Should companies accommodate variability or reduce it? Accommodation often involves asking employees to compensate for the variations among customers--a potentially costly solution. Reduction often means offering a limited menu of options, which may drive customers away. Some companies have learned to deal with customer-introduced variability without damaging either their operating environments or customers' service experiences. Starbucks, for example, handles capability variability among its customers by teaching them the correct ordering protocol. Dell deals with arrival and request variability in its high-end server business by outsourcing customer service while staying in close touch with customers to discuss their needs and assess their experiences with third-party providers. The effective management of variability often requires a company to influence customers' behavior. Managers attempting that kind of intervention can follow a three-step process: diagnosing the behavioral problem, designing an operating role for customers that creates new value for both parties, and testing and refining approaches for influencing behavior.

PinaColada: peptide-inhibitor ant colony ad-hoc design algorithm.

Design of protein-protein interaction (PPI) inhibitors is a major challenge in Structural Bioinformatics. Peptides, especially short ones (5-15 amino acid long), are natural candidates for inhibition of protein-protein complexes due to several attractive features such as high structural compatibility with the protein binding site (mimicking the surface of one of the proteins), small size and the ability to form strong hotspot binding connections with the protein surface. Efficient rational peptide design is still a major challenge in computer aided drug design, due to the huge space of possible sequences, which is exponential in the length of the peptide, and the high flexibility of peptide conformations. In this article we present PinaColada, a novel computational method for the design of peptide inhibitors for protein-protein interactions. We employ a version of the ant colony optimization heuristic, which is used to explore the exponential space ([Formula: see text]) of length n peptide sequences, in combination with our fast robotics motivated PepCrawler algorithm, which explores the conformational space for each candidate sequence. PinaColada is being run in parallel, on a DELL PowerEdge 2.8 GHZ computer with 20 cores and 256 GB memory, and takes up to 24 h to design a peptide of 5-15 amino acids length.

2016-02-01

We performed a metaanaysis of peer-reviewed studies involving implantation of a multifocal intraocular lens (IOL) in presbyopic patients with cataract or having refractive lens exchange (RLE). Previous reviews have considered the use of multifocal IOLs after cataract surgery but not after RLE, whereas greater insight might be gained from examining the full range of studies. Selected studies were examined to collate outcomes with monocular and binocular uncorrected distance, intermediate, and near visual acuity; spectacle independence; contrast sensitivity; visual symptoms; adverse events; and patient satisfaction. In 8797 eyes, the mean postoperative monocular uncorrected distance visual acuity (UDVA) was 0.05 logMAR ± 0.006 (SD) (Snellen equivalent 20/20(-3)). In 6334 patients, the mean binocular UDVA was 0.04 ± 0.00 logMAR (Snellen equivalent 20/20(-2)), with a mean spectacle independence of 80.1%. Monocular mean UDVA did not differ significantly between those who had a cataract procedure and those who had an RLE procedure. Neural adaptation to multifocality may vary among patients.

We have analyzed the effects of various human interferons produced in bacteria and the antileukemic compound mezerein (MEZ) on growth and melanogenesis in human melanoma cells. In four human melanoma cell lines, recombinant human fibroblast interferon (IFN-beta) was more active than recombinant human leukocyte interferons (IFN-alpha A, IFN-alpha D, or IFN-alpha A/D (Bgl] in inhibiting cellular proliferation. When monolayer cultures were exposed to 1000 IU/ml IFN-beta for four days the degree of growth inhibition in the different melanoma cell lines varied between 94 and 26%. Similarly, four days growth in medium containing 10 ng/ml MEZ resulted in either no inhibition of growth or as much as 53% inhibition of growth, depending on the specific melanoma cell line tested. MEZ induced dendrite-like processes, cytoplasmic projections morphologically similar to those normally found in neurons and melanocytes, in all four melanoma cell lines, whereas none of the interferons tested had this effect. The combination of interferon and MEZ resulted in a dramatic inhibition in cellular proliferation in all four melanoma cell lines. When cell extracts were assayed for melanin content, a marker of melanoma cell differentiation, the combination of IFN-beta and MEZ resulted in higher levels of melanin than with either agent alone. Dendrite-like formation was also prominent in the cultures treated with this combination. These results indicate that the antiproliferative effect of interferon toward human melanoma dells can be enhanced by treatment with MEZ and that this effect is associated with an enhancement of terminal differentiation.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder. The aggregation of Aβ peptides, Aβ1-42 in particular, is thought to be a fundamental pathogenic mechanism leading to the neuronal damage in AD. Recently, monosialoganglioside GM1 is reported to possess pivotal neuroprotection in neurodegenerative diseases. Previous studies have focused on the conformational dynamics and the biochemical interaction of the amyloid-peptide with the GM1 ganglioside, as well as the protective effect of GM1 on cognition. However, the phenomenon of autophagy with regard to neuronal dysfunction in AD is less investigated. In the present study, GM1 treatment were investigated in an AD mouse model and cultured PC12 dells to examine cognition-protective and neuroprotective effects of GM1. Furthermore, GM1 was found to induce autophagy via testing light chain 3 (LC3), Beclin1, neighbor of BRCA1 gene 1 protein and p62 (a substrate of LC3). Chloroquine, an inhibitor of lysosomal, was used to exclude the interference of lysosome, which could fuse with autophagosome and then clear it. In the presence of the inhibitor of autophagy (3-methyladenine; 3-MA), the protective effect of GM1 on PC12 cells in Aβ (1-42) induced toxic conditions was diminished. Interestingly, the expression of histone deacetylase 1 was increased in PC12 cells when treated with GM1, indicating that autophagy might be activated by GM1 through a pathway integrates protein acetylation. This study provides a novel insight into the protective role of GM1 against Aβ (1-42)-induced neurotoxicity via enhancing autophagy.

BEN22 detergent was studied for its ability to detach Acanthamoeba from soft contact lenses without mechanical cleaning or separate cleaning agents. Trophozoites of Acanthamoeba castellanii and A. polyphaga were adhered onto nonionic, high water content soft contact lenses. The lenses were immersed for 2 hours in contact lens care solutions and the remaining trophozoites were counted microscopically. The counts were compared to the counts on the same lens before treatment. BEN22 (50:50 mixture of L-alpha-L-rhamnopyranosyl-beta-hydroxydecanoyl-beta-hydroxydecanoate and 2-O-alpha-L-rhamnopyranosyl-alpha-L-rhamnopyranosyl-beta-hydroxydecanoyl-beta-hydroxydecanoate) (Kassell Industries, Inc., Wisconsin Dells, WI) in a concentration of 0.05% detached the trophozoites to a statistically significant greater extent than saline, but commercial ReNu Multi-Purpose Solution (Bausch & Lomb, Italy) and BioSoak (Finnsusp Ltd., Finland) did so as well. ReNu Multi-Purpose Solution was more effective than 0.005% BEN22 in detaching the trophozoites of both of the Acanthamoeba strains. After the 2 hour immersion period, a maximum of 97% of the initial trophozoites were detached. The variation between individual lenses was significantly greater than that within the different areas of one lens. BEN22 had no reliable detaching effect on Acanthamoeba. The variation between lenses was great, and the rate of detachment was low with all the agents tested indicating that immersion and rinsing in the solutions tested cannot be considered as a safe substitute for proper disinfection against Acanthamoeba in contact lens care.

We compared the follow-up data on loop diuretic use and renal function, as assessed by serum creatinine levels, and the estimated glomerular filtration rate (eGFR), of two groups of consecutive ambulatory HF patients: 1) the clinically-guided group, in which management was clinically driven based on the institutional protocol of the HF Unit of the Cardiovascular and Thoracic Department of Pisa (standard of care) and 2) the echo and B-type natriuretic peptide (BNP) guided group (patients conforming to the protocol of the Network Labs Ultrasound (NEBULA) in HF Study Group: Pisa, Perugia, Pavia; Verona, Auckland, and Veruno), in which therapy was delivered according to the serial assessment of BNP and echocardiography. Patients whose follow-up was based on standard of care had a significant higher prevalence of worsening renal function, that was likely related to higher diuretic dosages, whilst, a better management of renal function was observed in the echo-BNP-guided group. The data is related to "Echo and natriuretic peptide guided therapy improves outcome and reduces worsening renal function in systolic heart failure: An observational study of 1137 outpatients" (A.

Dolia are large pottery containers used in Roman times for the storage and fermentation of wine. They were produced in specialized pottery workshops ( figlinae) and were typically marked with specific epigraphical stamps, which represent a major tool to unravel their provenance and trade. In this work we present the preliminary results of a study of two dolia defossa, recently found at San Giovanni (Portoferraio, island of Elba, Italy) during 2012-2014 archaeological excavations in a Roman farm (late 2nd cent. BC-1st cent. AD), devoted to wine production and probably constituting the antecedent archaeological phase of the adjacent "Villa delle Grotte". Based on archaeological (epigraphic) evidence, five different production areas have been hypothesized: 1) Elba island, where the dolia have been found; 2) the municipal figlinae in the Pisa territory; 3) the middle catchment of the Tiber river (central Latium) where "urban" figlinae occurred; 4) the figlinae of Minturno (southern Latium), a locality known both for wine production and exportation and for the presence of ancient figlinae; 5) the municipal figlinae in the Volterra territory. Archaeometric analysis of tempering agents intentionally added to the clay for the manufacturing of the dolia, particularly magmatic lithic fragments and clinopyroxene crystals, allowed us to suggest that the watershed of the central Tiber Valley - including different volcanic centres belonging to both Tuscany Magmatic Province (Monti Cimini) and Roman Magmatic Province (Monti Vulsini and Vico volcano) - could have been the most likely sites of production of the dolia found at San Giovanni. Alternatively, the site of Minturno (southern Latium) could be proposed.

Myelodysplastic syndromes (MDS) are a heterogeneous group of clonal disorders, with very different prognosis in given individuals; age and comorbidities are emerging as relevant patient-related factors influencing clinical outcome in MDS. Our aim was to evaluate the impact of age, comorbidities and disease severity (IPSS and IPSS-R prognostic scores) in a "real-life" series of MDS patients. 318 patients with available assessment of comorbidities at diagnosis and consecutively registered into the Registro Ligure delle Mielodisplasie were analyzed. Comorbidities were evaluated according to HCT-CI and MDS-CI comorbidity indexes. Overall survival (OS) and the probability of death among patients who did not develop acute myeloid leukemia (NLD cumulative incidence) were analyzed. Comorbidities were seen in 177 (55.7%) patients. An older age (>75 y) had a significant negative impact on OS (p=0.008). HCT-CI was not associated with OS. MDS-CI was of prognostic significance (p=0.001), but the association was limited to pts with IPSS or IPSS-R "lower-risk". In multivariate analysis, MDS-CI remained an independent factor associated with OS and with an increased risk of NLD both when controlling for IPSS (p=0.019 and p=0.001, respectively) and for IPSS-R (p=0.048 and p=0.002, respectively). Evaluation of age and comorbidities according to a tailored tool such is MDS-CI helps to predict survival in patients with MDS and should be incorporated to current prognostic scores.

Ion chromatography characterization of polysaccharides in ancient wall paintings.

PubMed

Colombin, Maria Perla; Ceccarini, Alessio; Carmignani, Alessia

2002-08-30

An analytical procedure for the characterisation of polysaccharides and the identification of plant gums in old polychrome samples is described. The procedure is based on hydrolysis with 2 M trifluoroacetic acid assisted by microwaves (20 min, 120 degrees C, 500 W), clean-up of the hydrolysate by an ion-exchange resin, and analysis by high-performance anion-exchange chromatography with pulsed amperometric detection. Using this method the hydrolysis time was reduced to 20 min and the chromatographic separation of seven monosaccharides (fucose, rhamnose, arabinose, galactose, glucose, mannose, xylose) and two uronic acids (galacturonic and glucuronic) was achieved in 40 min. The whole analytical procedure allows sugar determination in plant gums at picomole levels, with an average recovery of 72% with an RSD of 8% as tested on arabic gum. The analytical procedure was tested with several raw gums, watercolour samples and reference painting specimens prepared according to old recipes at the Opificio delle Pietre Dure of Florence (Italian Ministry of Cultural Heritage, Italy). All the data collected expressed in relative sugar percentage contents were submitted to principal components analysis for gum identification: five groups were spatially separated and this enabled the identification of arabic, tragacanth, karaya, cherry+ghatty, and guar+locust bean gum. Wall painting samples from Macedonian tombs (Greece) of the 4th-3rd Centuries B.C., processed by the suggested method, showed the presence of a complex paint media mainly consisting of tragacanth and fruit tree gums. Moreover, starch had probably been added to plaster as highlighted by the presence of a huge amount of glucose.

Early Levallois and the beginning of the Middle Paleolithic in central Italy

In the second half of the 19th century Pleistocene faunas were discovered in two sites, Sedia del Diavolo and Monte delle Gioie, contained in deposits of the Aniene River in the area of Rome (Latium, Italy). Fieldwork by A.C. Blanc in the late 1930’s proved the association of fauna and lithic industry within fluvial deposits interbedded with volcanoclastic layers. A human femoral diaphysis and a metatarsal were later identified in the faunal assemblage from Sedia del Diavolo and evaluated as Neandertal. The lithic assemblages from these two sites were the basis of the definition of the Protopontinian by M. Taschini, which she viewed as a late Middle Pleistocene industry very similar to the later, Upper Pleistocene Pontinian industries, thought to be characteristic of the Latium Mousterian. The chronostratigraphic framework of the Aniene river deposits has been recently updated and the lithic assemblages from these two sites are now confidently dated between 295 and 290 ka, close to the transition from MIS 9 to MIS 8. They fit chronologically between the industries of layers m and d from Torre in Pietra, a site 26 km northwest of Rome. The presence of the Levallois debitage is indisputable yet it occurs within an original technical context, different from what is known in other early occurrences of the Levallois. The date confirms the proposed chronology for the early Levallois in Europe. More importantly these two assemblages demonstrate that this technology can emerge in more diversified contexts than usually described. This suggests that its dispersal in Europe may have been rapid.

Active edge control in the precessions polishing process for manufacturing large mirror segments

The segmentation of the primary mirror is the only promising solution for building the next generation of ground telescopes. However, manufacturing segmented mirrors presents its own challenges. The edge mis-figure impacts directly on the telescope's scientific output. The `Edge effect' significantly dominates the polishing precision. Therefore, the edge control is regarded as one of the most difficult technical issues in the segment production that needs to be addressed urgently. This paper reports an active edge control technique for the mirror segments fabrication using the Precession's polishing technique. The strategy in this technique requires that the large spot be selected on the bulk area for fast polishing, and the small spot is used for edge figuring. This can be performed by tool lift and optimizing the dell time to compensate for non-uniform material removal at the edge zone. This requires accurate and stable edge tool influence functions. To obtain the full tool influence function at the edge, we have demonstrated in previous work a novel hybrid-measurement method which uses both simultaneous phase interferometry and profilometry. In this paper, the edge effect under `Bonnet tool' polishing is investigated. The pressure distribution is analyzed by means of finite element analysis (FEA). According to the `Preston' equation, the shape of the edge tool influence functions is predicted. With this help, the multiple process parameters at the edge zone are optimized. This is demonstrated on a 200mm crosscorners hexagonal part with a result of PV less than 200nm for entire surface.

A multi-physical approach developed for the hydrodynamic characterization of porous media using hydrogeophysical information is presented. Several pumping tests were performed in the Hydrogeosite Laboratory, a controlled full-scale site designed and constructed at the CNR-IMAA (Consiglio Nazionale delle Ricerche - Istituto di Metodologia per l'Analisi Ambientale), in Marsico Nuovo (Basilicata Region, Southern Italy), in order to obtain an intermediate stage between laboratory experiments and field survey. The facility consists of a pool, used to study water infiltration processes, to simulate the space and time dynamics of subsurface contamination phenomena, to improve and to find new relationship between geophysical and hydrogeological parameters, to test and to calibrate new geophysical techniques and instruments. Therefore, the Hydrogeosite Laboratory has the advantage of carrying out controlled experiments, like in a flow cell or sandbox, but at field comparable scale. The data collected during the experiments have been used to estimate the saturated hydraulic conductivity ks [ms-1] using a coupled inversion model working in transient conditions, made up of the modified Richards equation describing the water flow in a variably saturated porous medium and the Poisson equation providing the self-potential ϕ [V], which naturally occurs at points of the soil surface owing to the presence of an electric field produced by the motion of underground electrolytic fluids through porous systems. The result obtained by this multi-physical numerical approach, which removes all the approximations adopted in previous works, makes a useful instrument for real heterogeneous aquifer characterization and for predictive analysis of its behavior.

To establish a colorimetrical characterization model of LCDs, an experiment with EIZO CG19, IBM 19, DELL 19 and HP 19 LCDs was designed and carried out to test the interaction between RGB channels, and then to test the spectral additive property of LCDs. The RGB digital values of single channel and two channels were given and the corresponding tristimulus values were measured, then a chart was plotted and calculations were made to test the independency of RGB channels. The results showed that the interaction between channels was reasonably weak and spectral additivity property was held well. We also found that the relations between radiations and digital values at different wavelengths varied, that is, they were the functions of wavelength. A new calculation method based on piecewise spectral model, in which the relation between radiations and digital values was fitted by a cubic polynomial in each piece of wavelength with measured spectral radiation curves, was proposed and tested. The spectral radiation curves of RGB primaries with any digital values can be found out with only a few measurements and fitted cubic polynomial in this way and then any displayed color can be turned out by the spectral additivity property of primaries at given digital values. The algorithm of this method was discussed in detail in this paper. The computations showed that the proposed method was simple and the number of measurements needed was reduced greatly while keeping a very high computation precision. This method can be used as a colorimetrical characterization model.

The contribution is focused on Alessandro Antonelli's project for the seat of the new italian parliament in Turin. The project, unrealized, began back in 1860, when the annexation to the Piedmont of Tuscany and the Emilia asked for the building in the capital of a decent seat for the National Parliament. It had to be situated on the area of the ex Carignano garden, behind the homonym building and the "antonellian" Collegio delle Provincie, in the heart of the city, that comes to be as representative place of the absolutist and dynastic power, through the phases of XVIIIth century of amplification and architectural-urbanism new configuration. To deepen therefore the knowledge of Antonelli's project and to understand better the reasons that have brought to the choice to locate in Palazzo Carignano the Italian Parliament, is has been chosen to deepen the relationships between the building and the city, through a punctual iconografic and archivistic documentation that it has allowed to read the development of the building among XVIIth and XIXth century, also in relationship to the urban transformation, putting to comparison the various projects of the contest with the Baroque existence. Through the restitution of virtual images it has been possible to optimize the hypothesis, putting not only to fire the philosophy of the project, but above all Antonelli's way to measure himself with such an incisive existence in the city as the "guariniano" Palazzo Carignano and to bring back the linguistic choice to the amplest circle of the works that the architect realized in the city of Turin.

In the attempt to establish key therapy definitions and provide shared approaches to invasive fungal diseases in neutropenic patients, trials of empiric, preeemptive and targeted antifungal therapy (EAT, PAT and TAT) were reviewed, and a Consensus Development Conference Project was convened. The Expert-Panel concurred that all antifungal treatments, including EAT, should always follow an adequate diagnostic strategy and that the standard definition of PAT may be misleading: being PAT guided by the results of a diagnostic work-up, it should better be termed diagnostic-driven antifungal therapy (DDAT). The Expert-Panel agreed that radiological findings alone are insufficient for the choice of a TAT and that the identification of the etiologic pathogen is needed. The Consensus Agreement proceeded identifying which clinical and microbiological findings were sufficient to start a DDAT and which were not. Finally, an algorithm to rationalize the choice of antifungal drugs on the basis of clinical manifestations, antifungal prophylaxis, instrumental and laboratory findings was drawn up.

Annelid polychaetes have been seldom the focus of dedicated DNA barcoding studies, despite their ecological relevance and often dominance, particularly in soft-bottom estuarine and coastal marine ecosystems. Here, we report the first assessment of the performance of DNA barcodes in the discrimination of shallow water polychaete species from the southern European Atlantic coast, focusing on specimens collected in estuaries and coastal ecosystems of Portugal. We analysed cytochrome oxidase I DNA barcodes (COI-5P) from 164 specimens, which were assigned to 51 morphospecies. To our data set from Portugal, we added available published sequences selected from the same species, genus or family, to inspect for taxonomic congruence among studies and collection location. The final data set comprised 290 specimens and 79 morphospecies, which generated 99 Barcode Index Numbers (BINs) within Barcode of Life Data Systems (BOLD). Among these, 22 BINs were singletons, 47 other BINs were concordant, confirming the initial identification based on morphological characters, and 30 were discordant, most of which consisted on multiple BINs found for the same morphospecies. Some of the most prominent cases in the latter category include Hediste diversicolor (O.F. Müller, 1776) (7), Eulalia viridis (Linnaeus, 1767) (2) and Owenia fusiformis (delle Chiaje, 1844) (5), all of them reported from Portugal and frequently used in ecological studies as environmental quality indicators. Our results for these species showed discordance between molecular lineages and morphospecies, or added additional relatively divergent lineages. The potential inaccuracies in environmental assessments, where underpinning polychaete species diversity is poorly resolved or clarified, demand additional and extensive investigation of the DNA barcode diversity in this group, in parallel with alpha taxonomy efforts. © 2015 John Wiley & Sons Ltd.

Hubble Space Telescope Image: Planetary Nebula IC 4406

This Hubble Space Telescope image reveals a rainbow of colors in this dying star, called IC 446. Like many other so-called planetary nebulae, IC 4406 exhibits a high degree of symmetry. The nebula's left and right halves are nearly mirror images of the other. If we could fly around IC 446 in a spaceship, we would see that the gas and dust form a vast donut of material streaming outward from the dying star. We do not see the donut shape in this photograph because we are viewing IC 4406 from the Earth-orbiting HST. From this vantage point, we are seeing the side of the donut. This side view allows us to see the intricate tendrils of material that have been compared to the eye's retina. In fact, IC 4406 is dubbed the 'Retina Nebula.' The donut of material confines the intense radiation coming from the remnant of the dying star. Gas on the inside of the donut is ionized by light from the central star and glows. Light from oxygen atoms is rendered blue in this image; hydrogen is shown as green, and nitrogen as red. The range of color in the final image shows the differences in concentration of these three gases in the nebula. This image is a composite of data taken by HST's Wide Field Planetary Camera 2 in June 2001 and in January 2002 by Bob O'Dell (Vanderbilt University) and collaborators, and in January by the Hubble Heritage Team (STScI). Filters used to create this color image show oxygen, hydrogen, and nitrogen gas glowing in this object.

Deep change. How operational innovation can transform your company.

Hammer, Michael

Breakthrough innovations--not just steady improvements--in operations can destroy competitors and shake up entire industries. Just look at Dell, Toyota, and Wal-Mart. But fewer than 10% of large companies have made serious attempts to achieve operational innovation. Why? One reason, contends the author, is that business culture undervalues operations--they're not as sexy as deals or acquisitions. In addition, many executives who rose through the ranks of finance or sales aren't familiar with operations--and they aren't interested in learning more. Finally, because no one holds the title Vice President of Operational Innovation, it doesn't have a natural home in the organization, so it's easily overlooked. Fortunately, all of these barriers can be overcome. This article offers practical advice on how to develop operational innovations, such as looking for role models outside your industry to emulate and identifying--and then defying--constraining assumptions about how work should be done. The author also discusses the best way to implement operational innovations. For instance, because they are disruptive by nature, projects should be concentrated in those activities with the greatest impact on enterprise strategic goals. Operational innovation may feel unglamorous or unfamiliar to many executives, but it is the only lasting basis for superior performance. Executives who understand how operational innovation happens--and who understand the barriers that prevent it from happening--can add to their strategic arsenal one of the most powerful competitive weapons in existence. In an economy that has overdosed on hype and in which customers rule as never before, operational innovation offers a meaningful and sustainable way to get ahead--and stay ahead--of the pack.

In order to clarify taxonomic problems relating to the identity of Scolelepis (Scolelepis) specimens from the Black Sea, the identified material was compared with specimens of Scolelepis cirratulus (Delle Chiaje, 1829) from the Mediterranean, of S. squamata (Abildgaard, in O.F. Müller, 1806) from the North Sea and the Atlantic coast of Spain, and with the syntypes of S. mesnili (Bellan & Lagardère, 1971) from the Atlantic coast of France. The examination of a large number of specimens (both juveniles and adults) reveals that the currently accepted morphological differences distinguishing all species show size-related patterns, suggesting that they all belong to one species. Therefore, this study supports the view that Scolelepis cirratulus and Scolelepis mesnili are junior synonyms of Scolelepis (Scolelepis) squamata. As a result of the re-assessment of the species limits of Scolelepis (Scolelepis) squamata, a new species, Scolelepis (Scolelepis) neglecta sp. nov., is distinguished and described from the Cantabrian coast of Spain. It inhabits shallow sublittoral fine sands and was earlier misidentified and reported from the Atlantic coast of Europe and the Mediterranean Sea as Scolelepis squamata, Scolelepis mesnili, Scolelepis cantabra (Rioja, 1918), or Dispio uncinata Hartman, 1951. The new species is characterized by having a trilobate prostomium with an acuminate medial portion, a short peristomium with well-developed dorso-lateral wings, short palps with two longitudinal bands of elevated lobes, neuropodial postchaetal lamellae notched from chaetigers 14-41, and strongly curved bidentate neuropodial hooded hooks with a slight constriction on the shaft starting from chaetigers 19-49. The morphology, diagnostic characters and ecology of both Scolelepis (Scolelepis) squamata and Scolelepis (Scolelepis) neglecta sp. nov. are discussed.
