  1. The power of virtual integration: an interview with Dell Computer's Michael Dell. Interview by Joan Magretta.

    PubMed

    Dell, M

    1998-01-01

    Michael Dell started his computer company in 1984 with a simple business insight. He could bypass the dealer channel through which personal computers were then being sold and sell directly to customers, building products to order. Dell's direct model eliminated the dealer's markup and the risks associated with carrying large inventories of finished goods. In this interview, Michael Dell provides a detailed description of how his company is pushing that business model one step further, toward what he calls virtual integration. Dell is using technology and information to blur the traditional boundaries in the value chain between suppliers, manufacturers, and customers. The individual pieces of Dell's strategy--customer focus, supplier partnerships, mass customization, just-in-time manufacturing--may be all be familiar. But Michael Dell's business insight into how to combine them is highly innovative. Direct relationships with customers create valuable information, which in turn allows the company to coordinate its entire value chain back through manufacturing to product design. Dell describes how his company has come to achieve this tight coordination without the "drag effect" of ownership. Dell reaps the advantages of being vertically integrated without incurring the costs, all the while achieving the focus, agility, and speed of a virtual organization. As envisioned by Michael Dell, virtual integration may well become a new organizational model for the information age.

    NASA Astrophysics Data System (ADS)

    Austin, Susan Eudy

    A case study is conducted implementing the Dell Streak seven-inch android device into eighth grade science classes of one teacher in a rural middle school in the Piedmont region of North Carolina. The purpose of the study is to determine if the use of the Dell Streaks would increase student achievement on standardized subject testing, if the Streak could be used as an effective instructional tool, and if it could be considered an effective instructional resource for reviewing and preparing for the science assessments. A mixed method research design was used for the study to analyze both quantitative and qualitative results to determine if the Dell Streaks' utilization could achieve the following: 1. instructional strategies would change, 2. it would be an effective instructional tool, and 3. a comparison of the students' test scores and benchmark assessments' scores would provide statistically significant difference. Through the use of an ANOVA it was determined a statistically significant difference had occurred. A Post Hoc analysis was conducted to identify where the difference occurred. Finally a T-test determined was there was no statistically significance difference between the mean End-of-Grade tests and four quarterly benchmark scores of the control and the experimental groups. Qualitative research methods were used to gather results to determine if the Streaks were an effective instructional tool. Classroom observations identified that the teacher's teaching styles and new instructional strategies were implemented throughout the pilot project. Students had an opportunity to complete a questionnaire three times during the pilot project. Results revealed what the students liked about using the devices and the challenges they were facing. The teacher completed a reflective questionnaire throughout the pilot project and offered valuable reflections about the use of the devices in an educational setting. The reflection data supporting the case study was drawn

    RIASSUNTO. Scopo. Lo scopo di questo studio è stato quello di investigare l'influenza della probabilità di suicidio, con le sue caratteristiche sociodemografiche, e di procurare i dati per la prevenzione del suicidio tra le guardie di sicurezza privata che lavorano in condizioni di stress, essendo a contatto ininterrottamente con eventi negativi e traumatici di vita durante il loro lavoro. Metodi. Hanno partecipato allo studio 200 guardie di sicurezza privata e 200 persone dell'Università di Ankara. Per raccogliere i dati sono stati utilizzati un questionario riguardante le condizioni sociodemografiche dei partecipanti, la Suicide Probability Scale (SPS) e la Brief Symptom Inventory (BSI). Risultati. Genere, stato civile, stipendio, credenze religiose, vivere una situazione di pericolo di vita, passato di tentativi di suicidio, fumare e non avere una malattia cronica hanno causato statisticamente una differenza significativa sui punteggi di SPS tra il gruppo di guardie di sicurezza privata e quello di controllo. In aggiunta, c'è stata una correlazione positiva statisticamente significativa tra i punteggi totali delle sottoscale di SPS e quelli di BSI. Conclusioni. Allo stesso modo degli agenti di polizia e dei gendarmi, le guardie di sicurezza privata sono ad alto rischio di commettere e tentare il suicidio trovandosi in condizioni stressanti di lavoro e anche soffrendo del trauma secondario. È necessario che essi siano consapevoli della propria tendenza al suicidio e avere controlli psichiatrici regolari.

    1990-07-01

    Stalagmitic floors interstratified with Mousterian deposits from the Caverna delle Fate (Italy) have been dated by the electron spin resonance (ESR) method. Three samples dated fall between 60,000 and 74,000 yr and indicate the age of the Mousterian deposits. They are in good agreement with ages determined by nondestructive γ-ray spectrometry of the human remains from 231Pa/ 235U and 230Th /234U ratios, which are, respectively, 75,000 -14,000+21,000 and 82,000 -25,000+36,000 yr. These dates are consistent with the morphological characteristics of the bones as Neanderthal remains.

    1980-01-01

    Carbon, oxygen and hydrogen isotope variations have been measured in samples from the epithermal fluorite vein deposit at Monte delle Fate, Latium. The ranges in ?? 13C and ??18O of calcite are -1.3 to 3.4 and 9.5 to 17.3, respectively. ??D values of water extracted from fluid inclusions are -49 to -39 for calcite and -41 to -34 for fluorite. Fluid inclusion filling temperatures (225??-240??C) and salinites (3.75) are nearly the same for both fluorite and sparry calcite. An elongated form of calcite, of minor abundance, precipitated at lower temperatures. The data indicate that (1) the CO2 involved in the mineralization was provided by the local marine limestones, (2) the waters were meteoric in origin and underwent an 18O shift of ??? 10 permil by exchange with marine country rocks, and (3) all geochemical features can be explained by the action of two hydrothermal fluids. Hot brines recently discovered in the Cesano geothermal area, 30 km to the east, have temperatures and some chemical characteristics similar to the hydrothermal fluids at Monte delle Fate. ?? 1980 Springer-Verlag.

    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

    RIASSUNTO. Scopo. I deficit delle funzioni esecutive (FE) sono frequentemente osservati nei disturbi dello spettro dell'autismo (ASD) e nel disturbo da deficit di attenzione con iperattività (ADHD). Lo scopo di questo studio è quello di valutare e confrontare le funzioni esecutive metacognitive ed emozionali/motivazionali di bambini con ASD e ADHD, sia fra di loro che con un gruppo di controllo. Metodi. Il campione è costituito da un totale di 58 soggetti, di cui 17 con ASD senza disabilità intellettiva, 18 con ADHD-manifestazione combinata e 23 con sviluppo tipico, abbinati per genere, età cronologica e livello intellettivo. Le valutazioni hanno riguardato alcune aree del funzionamento esecutivo, nello specifico pianificazione, flessibilità mentale, generatività e inibizione della risposta, che rappresentano sia le funzioni esecutive metacognitive sia quelle emozionali/motivazionali. Risultati. I risultati hanno rilevato un'ampia sovrapposizione delle disfunzioni esecutive nei due gruppi clinici con ASD e ADHD, e non sono stati indicativi della presenza di due profili realmente distinti del funzionamento esecutivo. Tuttavia, nell'ADHD è stato trovato un deficit più severo nell'inibizione della risposta prepotente (funzione emozionale/motivazionale). Conclusioni. I risultati del nostro studio sono parzialmente in accordo con quelli della letteratura. Ulteriori ricerche con gruppi più numerosi potranno chiarire più approfonditamente quali punti di forza e debolezza, nell'ampio spettro delle funzioni esecutive, differenzino fra loro le prestazioni di persone con ASD e ADHD.

    Isola delle Femmine Natural Reserve is a very little isle about 15 km from the centre of Palermo, in front of a plant for the production of cement and about 600 m from coast. In the present research, profiles soil PAHs were obtained for 16 sites within the reserve and for 8 stations on the rural soil taken as reference. summation Sigma PAHs, in the soil of investigated area, ranged from 35 to 545 microg/kg. With the aim to find the origin of PAHs in the soil of Isola delle Femmine, we compare the distribution of single analytes in the investigated area with those of the reference rural area (Monte Raffo Rosso), with those of atmospheric urban particulate collected at Palermo along with reported of emissions of some cement plants. The island's investigated area showed a high amount of 4- and 5-rings PAHs, whereas 3-ring PAHs are present mainly in the emission of cement plants (from literature). The percentage of 3-, 4-, 5- and 6-rings PAHs determined in samples of Isola delle Femmine are similar to those of the reference rural soils and to those of urban atmospheric particulate. Cement plant activity has a negligible weight on the presence of PAHs in the soil of Isola delle Femmine.

    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.

    PubMed

    Shallice, Tim; Buiatti, Tania

    2011-10-01

    The paper addresses a weakness in the Schwartz and Dell paper (2010)-namely, its discussion of the inclusion criteria for case series. The paper distinguishes the different types that exist and how they constrain the theoretical conclusions that one can draw about the organization of the normal cognitive system. Four different types of inclusion criteria are considered. Two are those treated by Schwartz and Dell-namely, theoretically derived clinical criteria, such as the example of semantic dementia, and broad clinical criteria such as the presence of aphasia. In addition, in the present paper two different types of anatomically based criteria are assessed-those using anatomical regions selected a priori and also regions selected as a result of an anatomical group study analysis. Putative functional syndromes are argued to be the empirical building blocks for cognitive neuropsychology. Anatomically based case series can aid in their construction or in their fractionation.

  12. Evidence for magma recharge and cumulate assimilation within the Fossa delle Felci (Salina Island, Italy) volcanic sequence

    Integrating plagioclase in situ chemical and textural analyses with MELTS (Ghiorso & Sack 1995) provides quantitative information about magma chamber processes such as recharge (R), assimilation (A) and fractional crystallization (FC) and constrains variables such as pressure, temperature and water content. Studies on Salina Island have documented volcanic sequences ranging from basalt to rhyolite that erupted between ~500-13 ka (Gertisser & Keller 2000). In the Fossa delle Felci sequence, basalts to basaltic andesites (herein called basalt) are the lowest units in the series followed upsection by dacite, andesite and basaltic andesite. Thirteen samples were chosen for whole rock major and trace element and Sr isotope analysis with a subset of six representative samples chosen for in situ textural and chemical analysis. The basalt shows the least complex plagioclase textures, as documented by Nomarski Differential Interference Contrast imaging. Textural complexity increases with increasing whole rock SiO2. No overlap occurs in core and rim anorthite (An mol%) values for the basalt, with varying degrees of overlap in core and rim An values for the remaining samples. The An range for all crystals is 93-39. Whole rock major and trace elements show systematic trends suggesting differentiation controlled by FC. The basalt displays anomalously high Al2O3, CaO and low MgO. For most samples, whole rock Sr behaves compatibly, but two andesites have anomalously high [Sr]. Overall, in situ plagioclase [Sr] range from 918-2312 ppm with the lowest values in the basalt and the highest in the dacite. Whole rock 87Sr/86Sr range from 0.70475-0.70433. Basaltic andesites are the least radiogenic, and andesites are the most radiogenic; thus, there are no simple correlations with indices of differentiation. Preliminary in situ LA-ICPMS analyses of one andesite yield 87Sr/86Sr of 0.70439-0.70408 with values decreasing rimward; all in situ values are lower than the whole rock value

  13. 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.

Ciò perchè le schematizzazioni più semplici suggerite dal senso comune, in virtù del quale piccole cause non possono produrre che piccoli effetti, e facenti capo a campi cinetici ovunque regolari, portano a risultati paradossali sconcertanti, quali il paradosso di d'Alembert.

    RIASSUNTO. La schizofrenia colpisce circa l'1% della popolazione e rappresenta un grave disturbo mentale con un notevole impatto anche sul funzionamento sociale, lavorativo e sulle attività della vita quotidiana. Le persone con schizofrenia hanno un tasso di mortalità superiore di 2-2,5 rispetto a quello della popolazione generale. La non aderenza ai farmaci antipsicotici è uno dei più importanti fattori di rischio per le ricadute e le ospedalizzazioni, sia nei pazienti con disturbo cronico sia al primo episodio, e conseguentemente contribuisce all'aumento dei costi sanitari. Gli antipsicotici atipici LAI possono migliorare l'aderenza al trattamento contribuendo a diminuire i tassi di ricaduta nei pazienti affetti da schizofrenia fin dall'esordio. Gli obiettivi primari nella gestione dei pazienti schizofrenici sono diretti, non solo alla riduzione dei sintomi nel breve termine, ma anche al mantenimento fisico e della funzionalità mentale, migliorando la qualità della vita e promuovendo il recupero del paziente. Scopo. Proporre un modello integrato, basato sulle evidenze, che fornisca un algoritmo efficace per il recupero del paziente schizofrenico e indagare l'efficacia e la sicurezza degli antipsicotici LAI nel trattamento, nel mantenimento, nella prevenzione delle ricadute e nella recovery dei pazienti affetti da schizofrenia. Metodi. Dopo un'accurata analisi di letteratura abbiamo identificato, raccolto e analizzato gli elementi qualificanti per un'ottimale gestione del paziente schizofrenico, definendo un modello di gestione e selezione delle alternative terapeutiche. Conclusioni. Il modello di gestione della schizofrenia proposto potrebbe consentire un migliore recupero funzionale del paziente grazie alla scelta di iniziare il percorso terapeutico, fin dalle prime fasi del disturbo soprattutto se in giovane età e al primo episodio, con un farmaco atipico LAI. All'interno dei farmaci antipsicotici atipici la formulazione LAI rappresenta una scelta

    Study of the Oweniidae specimens (Annelida; Polychaeta) from Lizard Island (Great Barrier Reef, Australia) stored at the Australian Museum, Sydney and newly collected in August 2013 revealed the presence of three species, namely Galathowenia quelis Capa et al., 2012 and two new species belonging to the genus Owenia Delle Chiaje, 1844. Owenia dichotoma n. sp. is characterised by a very short branchial crown of about 1/3 of thoracic length which bears short, dichotomously-branched tentacles provided with the major division close to the base of the crown. Owenia picta n. sp. is characterised by a long branchial crown of about 4/5 of thoracic length provided with no major divisions, ventral pigmentation on thorax and the presence of deep ventro-lateral groove on the first thoracic chaetiger. A key of Owenia species hitherto described or reported in South East Asia and Australasia regions is provided based on characters of the branchial crown.

    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

    This paper focuses on the potential of the latest generation of Airborne laser scanning (ALS) for the detection and the spatial characterization of microtopographic relief linked to ancient landscapes and palaeoenvironmental features. ALS is an optical measurement technique for obtaining high-precision information about the Earth's surface including basic terrain mapping (Digital terrain model, bathymetry, corridor mapping), vegetation cover (forest assessment and inventory), coastal, and urban areas. Recent studies examined the possibility of using ALS in archaeological investigations to identify earthworks, although the ability of ALS measurements in this context has not yet been studied in detail. In this study, the investigations based on ALS survey and aerial photos were carried out for the natural protected area, Bosco dell'Incoronata in the Apulia Region (Southern Italy). The investigated area is an important site from the naturalistic, historic and archaeological point of view. It is an ancient lowland forest, still present in the medieval time, which has been characterized by a long and intensive human activity from Neolithic to Middle Ages. The LiDAR based analysis allowed us to identify features not visible from ground or from optical data set because hidden by forest canopy and dense understory. The DTM enabled us to identify some microtopographic relief linked to traces of past landscapes, as in the case of the Cervaro paleaoriverbed. It is quite interesting to note that the river changed many times from North to South side compared to the present stream, and traces of past human activities can be still evident close to the diverse paleaoriverbeds. Nevertheless, intensive and systematic study of the ancient landscapes of the Bosco dell'Incoronata is just beginning and so far questions tend to be raised rather than answered. The current study emphasizes the potential of aerial LiDAR (Light Detection And Ranging) survey for detecting surface

    Southern Tuscany (Italy) hosts geothermal anomalies with associated widespread CO2 gas-rich manifestations and active travertine-deposing thermal springs. Geothermal anomalies have been active since the Late Miocene and have led to the formation of widespread Late Miocene-Pleistocene travertine deposits and meso- and epithermal mineralizations. This study investigates the travertine deposit exposed in the Castelnuovo dell'Abate area of southern Tuscany. Here, a fissure-ridge type travertine deposit and its feeding conduits, currently filled with banded calcite veins (i.e. banded travertine), represent a spectacular example of fossil hydrothermal circulation in the peripheral area of the exploited Monte Amiata geothermal field. The Castelnuovo dell'Abate travertine deposit and associated calcite veins were analysed to establish the characteristics of the parent hydrothermal fluids, and the age of this circulation. The focus of the study was on fluid inclusions, rarely considered in travertine studies, but able to provide direct information on the physico-chemical characteristics of the original fluid. Uranium-thorium geochronological data provided further constraints on the: (1) age of tectonic activity; (2) age of the hydrothermal circulation; and (3) evolution of the Monte Amiata geothermal anomaly. Results indicate that brittle deformation (NW- and SE-trending normal to oblique-slip faults) was active during at least the Middle Pleistocene and controlled a hydrothermal circulation mainly characterized by fluids of meteoric origin, and as old as 300-350 ka. This is the oldest circulation documented to date in the Monte Amiata area. The fluid chemical composition is comparable to that of fluids currently exploited in the shallow reservoir of the Monte Amiata geothermal field, therefore suggesting that fluid composition has not changed substantially over time. These fluids, however, have cooled by about 70 °C in the last 300-350 ka, corresponding to a cooling rate

  20. Origin and evolution of sinkholes in an alluvial setting: the case study of Piano dell'Acqua (San Basile, Northern Calabria, Italia)

    Five sinkholes have recently been identified at "Piano dell'Acqua", in the territory of San Basile (Northern Calabria, Southern Italy). They are located in a hilly setting, where the main landform is represented by a slight valley draining toward the east. The sinkholes are limited in size, with maximum diameter of 10 m, and maximum depth of 2.5 m. Two of them present elongated shapes, whilst the remaining three are circular. The area where the sinkholes developed is characterized by Pliocene conglomerate and sand, dislocated by tectonic lines. Sinkhole phenomena were initially investigated in the whole territory by means of multi-temporal aerial photos; the outcomes from this analysis were checked in the field through geological, structural and geomorphological surveys. Historical analysis was started in order to collect and critically evaluate the existing information and testimonies about the age of occurrence of the surveyed phenomena; several interviews with local inhabitants were performed, and a number of archives scrutinized. As a result, it may be assumed that two out of the five identified sinkholes developed during the winter 2000-2001 (period "a"), with likely rapid formation; two of the other cases probably originated during the 70's (period "b"), as also suggested by the age of the vegetation hosted within the sinkholes; c) the last sinkhole opened sometime between February 2001 and November 2007 (period "c"). According to the collected testimonies, a further phase of sinkhole development might have occurred in the first half of the past Centruty, but no field evidence of this older phase has been found. Analysis of the seismic catalogues showed that no earthquake can be identified as possible trigger of any of the sinkholes at Piano dell'Acqua. Therefore, the origin of the studied phenomena may be related to sub-cutaneous erosion, within an area that is rich in groundwater. Local changes in the water table, both related to climate and man

    The objectives of the present report were to give a baseline picture of hepatitis B notification incidence rates in children before the campaign of mass vaccination for newborns and adolescents (12-13 years old), and to study the role of different risk factors. Data from a specific national surveillance system of acute viral hepatitis (SEIEVA, Sistema Epidemiologico Integrato dell'Epatite Virale Acuta) were used and acute hepatitis B cases were compared to acute hepatitis A patients with the case-control study method to estimate the associations with the considered risk factors. Since the system began, one hundred and sixty-three local health departments have joined SEIEVA covering 30% of the Italian population. The incidence of acute hepatitis B notifications among 0-14 aged children was 9 per 100,000 in 1985 and 1 per 100,000 in 1990. Such decline in incidence was observed in both the North and the South of Italy. Surgical interventions, dental therapy and household contacts with a HBsAg chronic carrier were found to be associated with acute hepatitis B. The point estimate of the odds ratio was 10 for the latter risk factor. Other preventive measures in addition to vaccination are needed to control the risk of hepatitis B infection and other parenteral diseases due to surgical intervention and dental therapy.

  2. Fan sedimentation on continental margins: A comparison of Miocene Gulf Coast systems with the Middle Eocene Cozy Dell Formation of southern California

    Recent seismic and subsurface stratigraphic studies of the Miocene System, offshore Texas resulted in the development of a depositional model that documents and explains the deposition of sand-prone fans on the outer shelf during times when these areas were still covered by several hundred feet of water. This model suggests that sediment transport was by turbid flow and that sedimentation resulted in the development of leveed channel systems. The geometries and scales of these fan systems have been documented by three-dimensional seismic analysis and field-wide well penetrations in the Matagorda 668 field. It further advances the hypothesis that global eustatic levels were generally higher and basin water budgets greater during the Miocene than during later times in at least the Gulf Coast area. Translation of this model to outcrop areas is hampered in the Gulf Coast, and detail verification and refinement of the model has been restricted to subsurface work alone. This has also hampered the authors attempt to carry this model to non-Miocene-age systems. Work on the middle Eocene Cozy Dell Formation exposures in the Topatopa and Santa Ynez Mountains of southern California has revealed that this formation has a depositional history which may not be different than that interpreted for the Gulf Coast Miocene. This formation was deposited by turbidity currents in what has been interpreted to be an upper slope setting. The fans deposited by these currents have well-developed channel-levee complexes and display scales of geometry similar to those seen in the Gulf Coast Miocene. This formation displays seismic-sequence scale stratal geometries that suggest that it was deposited during lowstands of sea level.

    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

    We consider the Schrödinger equation with a combination of Deng-Fan-type and harmonic terms. To solve the corresponding differential equation, we split the equation to two parts: the parent and the perturbation terms. We use the Nikiforov-Uvarov technique to solve the parent part. For the perturbation part, we apply the series expansion method. Next, using the calculated wave function, we investigate some bottom and charm mesons within the Isgur-Wise function formalism. We present especially semileptonic {bar{B} rightarrow Dell bar{ν}} and {bar{B}s rightarrow D_s ell bar{ν }} decay widths, branching ratios and {|V_{cb}|} (element of the CKM matrix). Masses of some pseudoscalar mesons are also indicated. Comparisons of our results with experimental values and other approaches are included.

    The penumbral lunar eclipses equilibrate the probability of occurrence of solar and lunar eclipses over several years, but they are often neglected in the media and in the observations because of the difficulty of their identification due to the high luminosity of the full Moon. Three methods are presented to reduce this luminosity and to detect the penumbral phase of the lunar eclipse: the reflection on glass and water, the double polarizer and the short exposure photographs with 400 and 800 ISO and 1/500s of pose.

    Before 1510 there wasn't a single hospital in Southern Italy which took in mental patients, with the possible exception of L'ospedale degli Incurabili, which in any case dealt with other kinds of illnesses as well. Finally, in 1813 the decision was taken to found an institution in the city of Aversa which would deal exclusively with mental patients. This institution was put under the control of Giovanni Maria Linguiti. He took care of all patients using his therapeutic methods, with such excellent results that his reputation spread outside the kingdom. In 1816 in Sicily, an attempt was made to repeat the success of Aversa, but not until 1824 was it decided that L'ospizio di Santa Teresa should care for mental patients. Don Pietro Pisani was delegated to coordinate that hospital and, in 1827, he published a number of theories and guidelines concerning mental healthcare similar to those of Linguiti. In December 1864 a Royal Decree forced through parliament a statute which laid down the rules for the reorganization of these hospitals. Finally in August 1874, after numerous financial difficulties and struggles between political bodies and health service management, a Royal Decree was established and a new guiding statute was passed.

    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.

    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.

The purpose of this study is to quantify prevalence of PRMDs syntoms among the professional musicians and to verify their relative impact on quality lives. This study has investigated the orchestral staff of the principal lyric theatre of Rome to which it was distributed DASH OUTCOME and SF-36 questionnaires to identify the presence of musculoskeletal complaints for cervical brachial syndrome and the general quality of life respectively. The employment of the above methodology furnish statistically significant results, pointing out that the musicians quality life suffering from musculo-skeletal symptomatology (DASH SF > or = 15) was lower than ones without a clinical symptomatology. Subsequently these results were compared with the Italian population benchmarking values.

    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.

    2011-10-01

    In this commentary, though acknowledging that a case-series approach in neuropsychology is not always possible, we set out a series of considerations that in our view make this approach generally superior to single-case study. We argue that case-series designs are crucial for theory-testing, assessment of computational models, evaluation of inter-patient variation (including selection criteria, patient homogeneity/heterogeneity, premorbid individual differences, etc.) and to establish solid foundations for the interpretation of behavioural dissociations and associations. We conclude by suggesting that, alongside other neuroscience techniques, case-series cognitive neuropsychology provides a crucial contribution to the future of clinical and cognitive neuroscience.

    Coastal lagoons represent habitats with widely heterogeneous environmental conditions, particularly as regards salinity and temperature, which fluctuate in both space and time. These characteristics suggest that physical and ecological factors could contribute to the genetic divergence among populations occurring in coastal lagoon and open-coast environments. This study investigates the genetic structure of Holothuria polii at a micro-geographic scale across the Mar Menor coastal lagoon and nearby marine areas, estimating the mitochondrial DNA variation in two gene fragments, cytochrome oxidase I (COI) and 16S rRNA (16S). Dataset of mitochondrial sequences was also used to test the influence of environmental differences between coastal lagoon and marine waters on population genetic structure. All sampled locations exhibited high levels of haplotype diversity and low values of nucleotide diversity. Both genes showed contrasting signals of genetic differentiation (non-significant differences using COI and slight differences using 16S, which could due to different mutation rates or to differential number of exclusive haplotypes. We detected an excess of recent mutations and exclusive haplotypes, which can be generated as a result of population growth. However, selective processes can be also acting on the gene markers used; highly significant generalized additive models have been obtained considering genetic data from 16S gene and independent variables such as temperature and salinity.

    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.

McAnulty, J. B.

Goodwin, Econometrica, 19, 1-17 (1951): in form of the neutral differential equation with fixed delay and in form of the second order nonlinear ordinary differential equation. Both models demonstrate the possibility of oscillations of income (so-called Goodwin's oscillations). We have shown that for these models the excitation conditions for Goodwin's oscillations and the some its properties may be very different.

    This paper investigates the behaviour of interest rates in Turkey using a two-regime TAR model with an autoregressive unit root. This method recently developed by Caner and Hansen [Threshold autoregression with a unit roots, Econometrica 69 (6) (2001) 1555-1596] allows to simultaneously consider non-stationarity and non-linearity. Our finding indicates that the interest rate is a non-linear series and is characterized by a unit root process over the period 1990:1-2006:5.

    To make a further quantitative assessment of the relationship between cigarette smoking and the risk of myocardial infarction, a multicentric case-control study was conducted in Italy between September 1988 and June 1989 within the framework of the GISSI-2 trial. Ninety hospitals in various Italian Regions participated. 916 cases of acute myocardial infarction with no history of ischaemic heart disease and 1106 controls admitted to hospital for acute conditions not related to known or suspected risk factors for ischaemic heart disease were studied. Relative risks (RR) and 95% confidence intervals (CI) of myocardial infarction according to various measures of tobacco smoking, were adjusted for identified potential confounding factors using multiple logistic regression. Compared to lifelong non-smokers, the RR was 1.3 (95% CI 1.0 to 1.9) for ex-smokers, 2.0 (95% CI 1.4 to 2.9) for current smokers of less than 15 cigarettes per day, 3.1 (95% CI 2.2 to 4.2) for 15-24 cigarettes per day and 4.9 (95% CI 3.4 to 7.1) for 25 or more cigarettes per day. No trend in risk was evident for the duration, the RR being around 3 for subsequent categories. There was a significant interaction between smoking and age. Below the age 45, smokers of 25 or more cigarettes per day had a 33 times higher risk than non-smokers, compared to 7.5 at in the age group 45-54, 4.4 between the ages 55-64 and 2.5 at the age of 65 or over. The risk estimates were higher in women (RR for > or = 25 cigarettes per day = 10.1), in subjects in the lowest cholesterol tertile (RR = 11.9), with no history of diabetes (RR = 6.8), hypertension (RR = 9.5), no family history ischaemic heart disease (RR = 9.1) and low body mass index (RR = 9.3). The importance of smoking is confirmed as a cause of acute myocardial infarction: about 50% of all nonfatal infarctions in this Italian population could be attributable to cigarette smoking.(ABSTRACT TRUNCATED AT 250 WORDS)

    The relationship between frequency of consumption of eleven indicator foods (milk, meat, liver, carrots, green vegetables, fruit, eggs, ham, fish, cheese and alcohol) and serum cholesterol was investigated in the comparison group of a case-control study of acute myocardial infarction conducted in Italy. Data were collected on 792 subjects from various Italian regions, admitted to hospital for acute conditions unrelated to any known or potential risk factor for myocardial infarction or to long-term modifications in diet. No statistically or epidemiologically meaningful relationship emerged between serum cholesterol level and frequency of consumption of any of these foods. Cholesterol levels rose according to increasing consumption tertiles for most of the indicator foods considered. Higher values for the higher tertile of consumption were observed for meat, ham and eggs, but also for fruit, carrots and green vegetables. However, correlation coefficients between frequency of consumption of various food items and serum cholesterol level were uniformly low for all food items considered, ranging between -0.09 (for milk) and 0.19 (for ham). Although a more comprehensive diet history may lead to different indications, the present data are not suggestive of any major influence of long-term frequency of consumption of a few selected indicator foods on serum cholesterol levels.

    The relationship between physical activity and acute myocardial infarction (AMI) was examined in a case-control study conducted in Italy in 1988 to 1989 within the framework of the GISSI-2 trial of streptokinase versus alteplase and heparin versus no heparin in the treatment of AMI. A total of 916 case patients admitted to coronary care units from various Italian regions for AMI were interviewed. Control subjects were 1106 patients admitted to the same network of hospitals for a broad spectrum of acute diseases not related to known or potential risk factors for myocardial infarction. Among various types of physical activity (occupational activity, walking, stair climbing, and sport and leisure-time physical activity), occupational physical exercise emerged as the most protective. Multivariate odds ratios (ORs) were 1.4 (95% confidence interval (CI), 1.0 to 2.0) and 1.6 (95% CI, 1.2 to 2.1) for the two lowest levels of occupational physical activity. The trends of increasing risk with decreasing activity were consistent, although less strong, when other types of activity were considered. The protection conveyed by occupational physical activity was similar across various strata of sex, age, education, smoking habits, and diabetes, and was not explained by serum cholesterol, body weight, or hypertension. This study therefore confirms that low physical activity is an indicator of subsequent risk of AMI.

  7. Income and poverty in a developing economy

    2010-09-01

    We present a stochastic agent-based model for the distribution of personal incomes in a developing economy. We start with the assumption that incomes are determined both by individual labour and by stochastic effects of trading and investment. The income from personal effort alone is distributed about a mean, while the income from trade, which may be positive or negative, is proportional to the trader's income. These assumptions lead to a Langevin model with multiplicative noise, from which we derive a Fokker-Planck (FP) equation for the income probability density function (IPDF) and its variation in time. We find that high earners have a power law income distribution while the low-income groups have a Levy IPDF. Comparing our analysis with the Indian survey data (obtained from the world bank website: http://go.worldbank.org/SWGZB45DN0) taken over many years we obtain a near-perfect data collapse onto our model's equilibrium IPDF. Using survey data to relate the IPDF to actual food consumption we define a poverty index (Sen A. K., Econometrica., 44 (1976) 219; Kakwani N. C., Econometrica, 48 (1980) 437), which is consistent with traditional indices, but independent of an arbitrarily chosen "poverty line" and therefore less susceptible to manipulation.

  16. Analyzing Test-Taking Behavior: Decision Theory Meets Psychometric Theory.

    PubMed

    Budescu, David V; Bo, Yuanchao

    2015-12-01

    We investigate the implications of penalizing incorrect answers to multiple-choice tests, from the perspective of both test-takers and test-makers. To do so, we use a model that combines a well-known item response theory model with prospect theory (Kahneman and Tversky, Prospect theory: An analysis of decision under risk, Econometrica 47:263-91, 1979). Our results reveal that when test-takers are fully informed of the scoring rule, the use of any penalty has detrimental effects for both test-takers (they are always penalized in excess, particularly those who are risk averse and loss averse) and test-makers (the bias of the estimated scores, as well as the variance and skewness of their distribution, increase as a function of the severity of the penalty).

    2009-09-01

    This study follows Clark [P.K. Clark, A subordinated stochastic process model with finite variance for speculative prices, Econometrica 41 (1973) 135-155] and Chang, Chang and Lim [C.W. Chang, S.K. Chang, K.G. Lim, Information-time option pricing: Theory and empirical evidence, Journal of Financial Economics 48 (1998) 211-242] to subordinate an information-time based directing process into calendar-time based parent processes. A closed-form futures pricing formula is derived after taking into account the information-time setting and the stochasticity of the spot price, interest rate, and convenience yield. According to the empirical results on the TAIEX and TFETX data from 1998/7/21 to 2003/12/31, the information-time based model performs better than its calendar-time based counterpart and the cost of carry model, especially when the information arrival intensity estimates become larger.

  18. Physiological utility theory and the neuroeconomics of choice

    PubMed Central

    Glimcher, Paul W.; Dorris, Michael C.; Bayer, Hannah M.

    2006-01-01

    Over the past half century economists have responded to the challenges of Allais [Econometrica (1953) 53], Ellsberg [Quart. J. Econ. (1961) 643] and others raised to neoclassicism either by bounding the reach of economic theory or by turning to descriptive approaches. While both of these strategies have been enormously fruitful, neither has provided a clear programmatic approach that aspires to a complete understanding of human decision making as did neoclassicism. There is, however, growing evidence that economists and neurobiologists are now beginning to reveal the physical mechanisms by which the human neuroarchitecture accomplishes decision making. Although in their infancy, these studies suggest both a single unified framework for understanding human decision making and a methodology for constraining the scope and structure of economic theory. Indeed, there is already evidence that these studies place mathematical constraints on existing economic models. This article reviews some of those constraints and suggests the outline of a neuroeconomic theory of decision. PMID:16845435

  19. Valuation of stochastic interest rate securities with time-dependent variance

    NASA Astrophysics Data System (ADS)

    Villarroel, Javier

    2006-11-01

    We consider the problem of how to prize general securities whose payoff at maturity only depends on the interest rate rT at the time of exercise, where rt is supposed to be a stochastic Feller process. We show how to generalize the results of Cox et al. [Econometrica 53 (2) (1985) 385] regarding bond valuation to a situation where the stochastic evolution of rt under the martingale probability involves time-dependent coefficients and the payoff is arbitrary. The solution to this problem is given in terms of the propagator for the heat operator with a potential. This propagator is constructed in terms of a classical harmonic oscillator with time-dependent frequency.

    1968-01-01

    Secondary fermentation of sweet wine was prevented by the Delle stabilization procedure. For this procedure, advantage is taken of the inhibitory effects of high concentrations of sugar as well as of alcohol. Thus, relatively small amounts of wine spirits were added to fermenting musts to obtain stability, as compared to the conventional procedure in which larger amounts of alcohol are added and the inhibitory effect of alcohol only is considered. The Delle value is a function of the concentrations in the wine, after spirits addition, of alcohol and sugar. Delle values which gave stable wine were dependent on time of alcohol addition, on strain of wine yeast, and on composition of wine spirits. Fractional addition of spirits, concentration of SO2, and clarity of must had little effect on the Delle value. Sensory comparison of wines especially prepared for tasting by the Delle procedure and by the conventional procedure showed the wines made by the Delle procedure to be superior in quality. Under proper storage conditions, the Delle wines were shown to be microbiologically stable and resistant to wine spoilage organisms. Images Fig. 2 PMID:5664123

    The authors examine the relationship between doctor and patient during the consultation for the therapeutic decision for those couples who have to undergo a medical procreation, especially the ICSI by MESA and TESA. The couple's psycho-emotional involvement and the medical terminology hinder the real possibility of communication between doctor and patient. The data relating to a study of 80 couples done by the authors are presented. They show the need to improve the quality of communication between doctor and patient during the consultation. For this purpose, on the basis of the research conducted, modification of the language used and the support of audio-visual media are suggested during the consultation in order to reduce the percentage of the couple's doubts and uncertainties.

    2013-10-01

    Idaho is one of four states that have abolished the insanity defense. Hence, John Delling, on trial for two murders in Idaho, was unable to plead insanity or to argue that he lacked intent to kill, the only available option under Idaho law. After being sentenced to life in prison without parole, Delling challenged the constitutionality of Idaho's law. The state's supreme court rejected his appeal, holding that--despite the long history of the insanity defense and its widespread acceptance--there was no constitutional right to an insanity defense. Delling's petition to the U.S. Supreme Court was turned away, leaving the constitutional status of the insanity defense uncertain.

  19. L'eliosismologia: onde sismiche per studiare l'interno del Sole

    NASA Astrophysics Data System (ADS)

    Di Mauro, M. P.

    2014-12-01

    Negli ultimi cinquanta anni siamo stati testimoni di una straordinaria rivoluzione della conoscenza e comprensione della nostra stella grazie alla nascita dell'Eliosismologia, lo studio delle oscillazioni solari. Analogamente a ciò che accade nella Terra durante i terremoti, anche l'interno del Sole è pervaso continuamente da onde sismiche che provocano piccole oscillazioni, ovvero deformazioni della fotosfera. Le oscillazioni sono la manifestazione di diversi processi che avvengono all'interno della struttura del Sole e le frequenze sismiche dei modi osservati e misurati sulla superficie sono legate direttamente ai parametri fisici degli strati interni attraversati dalle onde sismiche. Lo studio delle oscillazioni rappresenta, quindi, l'unico metodo diretto per studiare la struttura e la dinamica interna del Sole. In questo articolo verranno illustrate le caratteristiche generali delle oscillazioni solari e verranno presentati i risultati importanti e i progressi notevoli raggiunti grazie all'Eliosismologia.

    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.

    INTRODUZIONE. In Italia negli ultimi anni l’aumento della sopravvivenza della popolazione ha comportato il cambiamento dello stato di salute, che vede l’incremento nella prevalenza delle patologie croniche (Osservatorio, 2011). L’ospedale, riservato alla fase acuta delle patologie, si integra necessariamente con le cure primarie. La continuità assume particolare rilevanza per la cura, assistenza e riabilitazione della persona assistita, così come l’appropriato utilizzo delle diverse tipologie di offerta socio sanitaria assistenziale e riabilitativa. OBIETTIVO. Al San Gerardo di Monza, nell’ambito della riabilitazione del paziente post-acuto, si analizza la fase che intercorre tra la dimissione prevista dall’ospedale e la data di accettazione presso gli istituti di riabilitazione. E’ possibile quantificare i tempi di attesa? L’ allocazione delle persone assistite è appropriata? Scopo dello studio osservazionale descrittivo è accertare la distribuzione dei giorni di attesa. Inoltre si ipotizza il ricorso all’Assistenza Domiciliare Integrata e a soluzioni innovative. Obiettivi sono la diminuzione delle giornate di degenza inappropriate e l’utilizzo delle risorse in modo congruo. RISULTATI. Delle 1083 persone in attesa di riabilitazione il 55% (652), a cui sono associate 4505 giornate “inappropriate”, è stato dimesso dall’ospedale oltre i tempi previsti. CONCLUSIONI. L’utilizzo dell’assistenza domiciliare, vantaggiosa per l’ospedale, può essere utilizzata solo per una minoranza di pazienti e in modo diseconomico. Per abbattere la totalità delle giornate, una soluzione innovativa può essere l’istituzione di posti letto a basso costo. E dato che la maggioranza dei casi sono solo ad alta complessità assistenziale ma a bassa intensità clinica potrebbero essere letti gestiti da infermieri.

    Introduzione. Secondo l'Organizzazione Mondiale della Sanità (OMS) le cadute e i danni ad esse correlati sono una problematica prioritaria per i sistemi sanitari e sociali in Europa e nel mondo, soprattutto tenendo conto del rapido accrescersi dell'aspettativa di vita. Scopo: Obiettivo del presente studio è descrivere incidenza, cause e modalità di caduta nell’Azienda Sanitaria Locale Cuneo 1 (ASL CN1) in seguito all’accorpamento del 2008. Metodo: L’indagine si articola in due fasi: 1. definizione dell'atteso sulla base di letteratura ed altre realtà comparabili; 2. analisi del contesto realizzata attraverso esame delle schede di segnalazione delle cadute compilate tra 1 Luglio 2010 - 30 Giugno 2011. Risultati: L’incidenza delle cadute nel periodo in esame è dello 0.8% e nel 69% dei casi la causa è rappresentata dai fattori intrinseci, seguiti da quelli estrinseci (7.4%), organizzativi (5.4%) e quelli legati a difficoltà comunicative interprofessionali (3.1%). Conclusioni: Data l'eziologia multifattoriale delle cadute, l'approccio più efficace per ridurne l'incidenza è quello multidimensionale; si comprende quindi l'importanza di un'azione simultanea su tre livelli: organizzativo, staff/comunicazione e paziente.

    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.

    Sommario SCOPO: Verificare il guadagno diagnostico dell'elastosonografia transrettale real-time (RTE) rispetto alla ecografia transrettale B-mode nel rilievo del tumore prostatico in una popolazione di pazienti con sospetto di neoplasia. MATERIALI E METODI: Ottantaquattro pazienti con sospetto clinico-laboratoristico di tumore prostatico sono stati valutati mediante ecografia transrettale, elastosonografia e biopsia transperineale. RISULTATI: L'esame bioptico è stato considerato lo standard di riferimento. Nella valutazione per paziente, la sensibilità dell'ecografia B-mode è stata del 56%; la specificità dell'80%; il valore predittivo positivo (VPP) del 70%, il valore predittivo negativo (VPN) del 67%. Nella valutazione sul totale dei prelievi bioptici la sensibilità è stata del 33%, la specificità del 92%, il VPP del 69%, il VPN del 73%. La RTE ha ottenuto i seguenti risultati nella valutazione per paziente: sensibilità 51%, specificità 75%, VPP 64% e VPN 64%. Nella valutazione sul totale dei prelievi bioptici: sensibilità 36%, specificità 93%, VPP 72%, VPN 74%. Confrontando i valori di accuratezza dell'ecografia B-mode e della RTE per i tumori della zona periferica, è stata trovata una differenza significativa. Nella valutazione sul totale dei prelievi bioptici della zona periferica la sensibilità dell'ecografia B-mode è stata del 48%, la specificità dell'81%, il VPP del 75%, il VPN del 58%. La RTE ha ottenuto i seguenti valori: sensibilità 66%, specificità 78%, VPP 77%, VPN 67%. CONCLUSIONI: La RTE rappresenta un valore aggiunto all'ecografia B-mode. Ha presentato un'accuratezza superiore rispetto all'esame B-mode nella valutazione della prostata periferica e nella possibilità di indirizzare i prelievi bioptici.

    Sommario INTRODUZIONE: L'artrite Idiopatica giovanile (AIG) determina alterazioni a carico della testa condilare dell'articolazione temporomandibolare (ATM). Nell'esordio oligo-articolare (OA) l'interessamento dell'ATM viene spesso trascurato perchè può essere asintomatico. Lo scopo di questo studio è quello di valutare la presenza di versamento intrarticolare (V) dell'ATM, mediante esame ecografico (US), nelle fasi precoci di malattia. MATERIALE E METODI: Sono stati studiati 68 bambini (57 bambine e 11 bambini, di età compresa tra 9,1 e 16, anni, età media: 11,02 ± 4,2 mesi) con AIG ad esordio OA. I pazienti (pz) erano sintomatici quando uno dei quattro sintomi seguenti era presente: 1) dolore ricorrente (a riposo o durante il movimento di apertura della bocca); 2) presenza di scrosci articolari; 3) presenza di limitazione nell'apertura della bocca; 4) locking intermittente. US è stato eseguito su entrambe le ATM sia in fase statica che dinamica, mediante ecografo General Electric (LOGIQ7) con sonda lineare (8,5 MHz) posizionata lungo l'asse maggiore del ramo condilare. Il V era presente quando lo spessore della capsula articolare era ≥1,5 mm. RISULTATI: 46/68 (68%) hanno presentato V a carico delle ATM; in 16 (35%) il V era bilaterale. 2/46 con V erano sintomatici, mentre in 44 non erano presenti sintomi. CONCLUSIONI: Questi dati suggeriscono che un'alta percentuale di bambini e giovani adulti con AIG ad esordio OA, nella fase iniziale della malattia, presenta un interessamento flogistico delle ATM anche in assenza di sintomi. L'US, non invasivo e facilmente ripetibile, ci offre importanti informazioni sul coinvolgimento articolare delle ATM ed è risultato utile nella diagnosi all'esordio.

  13. Execution without excuses. Interview by Thomas A. Stewart and Louise O'Brien.

    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."

  14. Accounting for trends in health poverty: a decomposition analysis for Britain, 1991-2008.

    PubMed

    Brzezinski, Michal

    2015-03-01

    We use data from the British Household Panel Survey to analyse changes in poverty of self-reported health from 1991 to 2008. We use the indices recently introduced by Bennett and Hatzimasoura (Poverty measurement with ordinal data. Institute for International Economic Policy, IIEP-WP-2011-14, 2011), which can be interpreted as ordinal counterparts of the classical Foster et al. (Econometrica 52(3):761-766, 1984) poverty measures. We decompose changes in self-reported health poverty over time into within-group health poverty changes and population shifts between groups. We also provide statistical inference for the Bennett and Hatzimasoura's (Poverty measurement with ordinal data. Institute for International Economic Policy, IIEP-WP-2011-14, 2011) indices. Results suggest that when "fair" self-reported health status is chosen as a health poverty threshold all of the used indices indicate the growth of health poverty in Britain. However, when the health poverty threshold is lower ("poor" self-reported health status) the increase in health poverty incidence was compensated by decreasing average health poverty depth and improving health inequality among those who are poor with respect to health. The subgroup decompositions suggest that the most important factors accounting for the changes in total health poverty in Britain include a rise of both health poverty and population shares of persons cohabiting and couples with no children as well as an increase of the population of retired persons.

  15. Non-robust dynamic inferences from macroeconometric models: Bifurcation stratification of confidence regions

    NASA Astrophysics Data System (ADS)

    Barnett, William A.; Duzhak, Evgeniya Aleksandrovna

    2008-06-01

    Grandmont [J.M. Grandmont, On endogenous competitive business cycles, Econometrica 53 (1985) 995-1045] found that the parameter space of the most classical dynamic models is stratified into an infinite number of subsets supporting an infinite number of different kinds of dynamics, from monotonic stability at one extreme to chaos at the other extreme, and with many forms of multiperiodic dynamics in between. The econometric implications of Grandmont’s findings are particularly important, if bifurcation boundaries cross the confidence regions surrounding parameter estimates in policy-relevant models. Stratification of a confidence region into bifurcated subsets seriously damages robustness of dynamical inferences. Recently, interest in policy in some circles has moved to New-Keynesian models. As a result, in this paper we explore bifurcation within the class of New-Keynesian models. We develop the econometric theory needed to locate bifurcation boundaries in log-linearized New-Keynesian models with Taylor policy rules or inflation-targeting policy rules. Central results needed in this research are our theorems on the existence and location of Hopf bifurcation boundaries in each of the cases that we consider.

    Introduzione. I dati statistici per il 2015 parlano di un peggioramento generale delle condizioni di vita e di salute della popolazione in Italia. Le possibili ricadute chiamano l’infermiere ad un coinvolgimento in tema di disuguaglianze nella salute. Lo studio è stato realizzato con lo scopo di valutare quanto gli infermieri conoscono e percepiscono la correlazione fra le condizioni di salute della popolazione e le iniquità di sistema. Metodo. E’ stato condotto uno studio esplorativo attraverso un aggiornamento bibliografico rispetto a precedenti lavori e la somministrazione di questionari a campioni di convenienza di professionisti e studenti di infermieristica e valutazione dei risultati secondo la prospettiva del mixed method. Risultati. La bibliografia infermieristica presente sul piano quantitativo è molto limitata. Il questionario fornisce risposte utili alla valutazione della percezione delle disuguaglianze nella salute in termini di equità orizzontale e verticale. Conclusioni. La conoscenza delle disuguaglianze nella salute non può essere al margine dei lavori scientifici e della stessa letteratura professionale. E’ necessario ridurre il divario fra gli aspetti valoriali propri della professione, che riverberano nella percezione delle iniquità esistenti, e l’assunzione piena del sapere correlato ai determinanti socio-economici della salute e della malattia.

  18. The role of plastic surgeon in complex cephalic malformations. Our experience.

    PubMed

    Chiumariello, Stefano; Del Torto, Giuseppe; Guarro, Giuseppe; Alfano, Carmine

    2014-01-01

    Le malformazioni complesse del distretto cefalico comprendono tutta una serie di anomalie di sviluppo che oltre a presentare una notevole difficoltà classificativa e di inquadramento, comprendono forme che sono talora di stretta pertinenza specialistica. La correzione delle malformazioni craniofacciali fa ricorso ad una disciplina chirurgica particolarmente esigente, che deve associare una formazione chirurgica di base con un apprendimento delle tecniche specifiche per il territorio craniofacciale e una conoscenza della patologia malformativa. L’eziologia malformativa pone il chirurgo davanti a problemi specifici, dominati dallo sviluppo della tecnica chirurgica. Si stabilisce dunque un protocollo terapeutico dopo aver identificato la malformazione, stimato la gravità delle alterazioni tissutali e valutato la capacità di crescita dei territori interessati. E’ fondamentale, oltre che il rimodellamento della morfologia, il recupero delle funzioni ed il trattamento rieducativo. E’ quindi evidente che si tratta di una chirurgia di equipe che può portare risultati positivi solo se realizzata con fiducia reciproca tra i vari operatori.

  20. Short communication: casein haplotype variability in sicilian dairy goat breeds.

    PubMed

    Gigli, I; Maizon, D O; Riggio, V; Sardina, M T; Portolano, B

    2008-09-01

    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.

  1. Case series in cognitive neuropsychology: promise, perils, and proper perspective.

    PubMed

    Rapp, Brenda

    2011-10-01

    Schwartz and 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 as well as a response to the six commentaries by Dell and Schwartz (2011 this issue). In this paper, I provide a brief summary of the key points made in Schwartz and Dell, 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.

    In a corpus analysis of spontaneous speech Jaeger and Snider (2007) found that the strength of structural priming is correlated with verb alternation bias. This finding is consistent with an implicit learning account of syntactic priming: because the implicit learning model implemented by Chang (2002), Chang, Dell, and Bock (2006), and Chang,…

  1. Empirical evidence of contrasting feedbacks between remotely sensed soil moisture and gauge-based precipitation in arid vs. humid areas of the United States

    NASA Astrophysics Data System (ADS)

    Tuttle, S. E.; Salvucci, G.

    2014-12-01

    Land surface moisture content affects the partitioning of radiative energy into heat and moisture fluxes at the land surface, and thus can affect the state of the overlying atmosphere by supplying water vapor, inducing moist convection and lateral convergence, and growing the planetary boundary layer. However, it is difficult to determine how this influence may in turn affect the propensity for subsequent precipitation. Empirical studies have disagreed on the sign and statistical significance of the estimated influence of soil moisture on precipitation, and have suffered from the difficulty of distinguishing a causal effect from lagged correlations that arise from the autocorrelation, seasonality, and interannual variability of each signal. Modeling studies can more easily establish causality, but feedback behavior has been shown to vary widely among models. We apply Granger Causality (Granger (1969), Econometrica, 37: 424-438) to quantitatively diagnose the relationship between soil moisture state and the occurrence of subsequent precipitation, and implement it over the contiguous United States using remotely sensed soil moisture and gauge-based precipitation observations. This is accomplished through a generalized linear model (GLM), specifically a probit regression model, constructed to estimate the observed record of precipitation occurrence. Predictor variables included in the regression account for external atmospheric and climatic influences on precipitation, the prior occurrence of precipitation, and previous day soil moisture anomalies. We find a generally positive soil moisture-precipitation feedback in the western part of the United States and a negative feedback in the east. These findings suggest that processes linking soil moisture to precipitation triggering may differ in arid versus humid climate regimes, and that soil moisture state can play an important role in determining future weather conditions.

    Sommario SCOPO: Valutare l'utilità dell'ecografia con ecoamplificatore e dell'elastosonografia nella caratterizzazione del nodulo tiroideo. MATERIALI E METODI: Periodo novembre 2006–luglio 2007, studiati 23 pazienti con nodulo solitario tiroideo, sottoposti a ecografia B-mode e power Doppler, ecografia con mezzo di contrasto, elastosonografia e FNAC (Fine Needle Aspiration Citology). Sedici pazienti sono stati sottoposti a tiroidectomia. RISULTATI: I 23 noduli studiati comprendevano 14 lesioni benigne e 9 maligne. Alla valutazione delle curve intensità/tempo le lesioni maligne presentavano un tempo di wash-in (8,8 ± 1,3 vs 12,1 ± 2,6 secondi; p = 0,002, t-test) e un tempo di picco (15,3 ± 4,6 vs 22,2 ± 3,9 secondi; p = 0,001, t-test) significativamente più precoci rispetto alle lesioni benigne. La fase di wash-out presentava andamento monofasico nel 70% dei noduli benigni e in nessuno dei maligni; polifasico nel 30% dei noduli benigni e nel 100% dei maligni. L'andamento polifasico è associato in maniera statisticamente significativa (p = 0,0007, χ) alla malignità. L'andamento polifasico ha mostrato sensibilità del 100%, specificità del 71%, VPP (valore predittivo positivo) del 69%, VPN (valore predittivo negativo) del 100% e accuratezza diagnostica dell'83%. Nel 78% (11/14) dei noduli benigni sono stati rilevati i pattern elastosonografici 1–2 (maggiore elasticità), nel 88% (8/9) dei noduli maligni i pattern 3–4 (minore elasticità). L'elastosonografia ha mostrato sensibilità dell'88%, specificità del 78%, VPP dell'72%, VPN del 91% e accuratezza diagnostica del 82%. Il pattern elastosonografico 3–4 è associato (p = 0,001, χ) alla malignità. CONCLUSIONI: L'ecografia con ecoamplificatore e l'elastosonografia possono rappresentare ausili diagnostici nella valutazione del nodulo tiroideo solitario, soprattutto quando la FNAC è non diagnostica, quando indica lesione follicolare e nei noduli <1 cm.

    2008-03-01

    Sommario PREMESSA: L'ecografia del torace soltanto di recente ha assunto una sua completa dignità di metodica diagnostica: esperti ecografisti, con esperienza pneumologica, hanno, infatti, dimostrato la possibilità di una applicazione degli ultrasuoni in ambito toraco-polmonare, soprattutto in situazioni critiche, quali quelle emergenti in urgenza, in terapia intensiva o in ambito pediatrico o in corso di gravidanze. SCOPO: Da queste premesse si origina il lavoro, che si propone di individuare, se esistenti, gli aspetti ultrasonografici delle polmoniti interstiziali a genesi infettiva, e il ruolo di supporto (alla radiologia) degli ultrasuoni anche in questo ambito. MATERIALI E METODI: Sono stati studiati 55 soggetti afferiti, nel quinqennio 2001–2006, alla UOS di Ecografia toracica (UOC Pneumologia I) dell'Ospedale M. Santo e dell'UOS di Ecografia Internistica (UOC di Medicina Generale) dell'Ospedale di Rogliano dell'AO di Cosenza, perché affetti da sospetta patologia infettiva respiratoria virale o simil-virale. Tali pazienti sono stati valutati con indagini clinico-funzionali e strumentali (anamnesi + es. obiettivo + esami ematochimici + prove di funzionalità respiratoria + broncoscopia + Rx e HRTC del torace) e con esame ecografico, in cieco, del torace. RISULTATI: Dalla valutazione comparativa tra dati clinico-laboratoristico-strumentali e dati ecografici è emerso che i 55 soggetti studiati sono risultati affetti da polmonite interstiziale. In tali soggetti la diagnosi è stata formulata con l'ausilio delle comuni tecniche di studio, ma anche l'esame US ha permesso la individuazione di segni considerati diagnostici (Lichtenstein) di patologia interstiziale. Dei soggetti esaminati, infatti, 31 (56,36%) hanno mostrato all'ecografia la presenza di artefatti a coda di cometa (>5 per lato) nelle regioni anteriore e laterale del polmone (dato patognomico di patologia interstiziale) e 24 (46,64%) di “quadri misti” (aree di addensamento

    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.

    Le ustioni della mano sono sempre state uno dei maggiori problemi per i chirurghi ricostruttori a causa della sua particolare anatomia e delle sue complesse funzioni. Una guarigione spontanea di lesioni profonde in queste aree può portare a risultati catastrofici: una copertura cutanea adeguata è fondamentale per tutte le funzioni. La copertura precoce dei tessuti molli residuanti è fondamentale al fine di evitare la formazione di contratture disabilitanti che con il tempo potrebbero determinare anchilosi articolare e retrazione tendinea. Escissione precoce e innesti cutanei rappresentano la terapia standard per le ustioni della mano; in alcuni casi quest’approccio è inapplicabile e, pertanto, il ricorso ai lembi diventa inevitabile. In questo articolo riportiamo un caso di ustione complessa del dorso della mano trattata in prima istanza con innesti cutanei e, quindi, con un lembo addominale, riuscendo ad ottenere un’ottima copertura ed un buon recupero delle funzioni.

  6. Kinetic Friction of Non-Coalescing and Non- Wetting Drops

    Neitzel, G. paul

    2004-01-01

    This project has focused on the experimental determination of the frictional forces associated with noncoalescing and nonwetting systems. In particular, the focus has been on friction associated with an isothermal nonwetting droplet sliding on a solid surface. The nonwetting phenomenon is driven by the establishment of a thin (of order microns in thickness) layer of lubricating gas that is swept by viscous action into the space between the liquid and solid, preventing them from coming into contact. The mechanism has been described in the review article by Neitzel & Dell'Aversana (2002). The work performed under this NASA GSRP sponsorship extends work done by Dell'Aversana & Neitzel (2004) on the load-carrying capacities of thermocapillary nonwetting droplets for a given relative displacement of the two surfaces in question.

    INTRODUZIONE. Lo stress occupazionale è una delle principali cause di malattie professionali e di assenze da lavoro e genera costi sanitari e sociali molto elevati; la comprensione del problema è stata l'obiet- tivo di numerosi studi. Monitorare lo stress negli infermieri può essere uno strumento per chi ha la responsabilità della gestione delle risorse umane nel sistema sanitario. La ricerca infermieristica italiana si è occupata solo marginalmente di stress lavorativo infermieristico. Gli obiettivi di questo studio sono dunque: stimare la prevalenza di stress tra gli infermieri di tre ospedali, in modo da disporre di dati epidemiologici per valutare la necessità di interventi di prevenzione e di trattamento del fenomeno; analizzare eventuali fattori di rischio e fattori protettivi in modo da progettare interventi preventivi mirati.

    An investigation is being developed by the Comitato Nazionale per la Ricerca e per lo Sviluppo dell'Energia Nucleare e delle Energie Alternative, ENEA, to assess the indoor exposure of the Italian population. The programme, which started in 1982, includes regional and local surveys in all the administrative districts and intensive investigations of factors which influence indoor radon levels. The survey is organized by statistical areas of sampling to obtain representative samples of houses. The definition of the areas takes into account basic parameters e.g. geolithological environments, radon soil gas from underlying soils and rocks, specific activities of local building materials, climatic and seasonal variations, building technology, types of houses and town planning. The collected data may also be used for the compilation of radon risk maps to plan special monitoring and remedial actions if needed. Preliminary results concerning the above items are discussed.

    Juveniles, like adults, should be afforded the right to raise an insanity defense. In this commentary on the article by Morse and Bonnie on the abolition of the insanity defense, we explain why so few juveniles across the United States are granted access to the insanity defense and the reasons that they should have that option. We also consider whether the Delling case was the best suited vehicle to argue for extending constitutional protection to the insanity defense nationwide.

    Cavenago, Dario; Mezzanzanica, Mario

    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.

    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.

    Sommario INTRODUZIONE: La displasia evolutiva dell'anca (DDH) costituisce la deformità più frequente dell'apparato locomotore. Lo screening ecografico è la metodica più utilizzata nell'identificazione della DDH, considerando la brevità del periodo in cui la diagnosi è possibile prima della comparsa dei sintomi clinici. Un intervento terapeutico appropriato precoce può avere un effetto positivo in relazione all'evoluzione di tale patologia. METODI: L'esame ecografico, la sua valutazione, la classificazione e la tipizzazione delle anche sono stati effettuati secondo il metodo descritto dal Graf. I pazienti sono stati valutati per mezzo di un'analisi retrospettiva volta a identificare i casi di DDH. Tutti i casi sono stati classificati e in base a ciò si è deciso il tipo di trattamento da attuare. RISULTATI: Complessivamente sono state osservate 145 anche in 122 bambini che presentavano un certo grado di displasia. L'età alla diagnosi variava da 14 a 90 giorni con una media di 52 giorni di vita. Un mese dopo la diagnosi ecografica le anche di tipo 2a, sia bilaterali che unilaterali, sono risultate normali nel 94%. Il restante 6% così come i tipi 2b, 2c, D e 3 sono stati trattati con un divaricatore e la guarigione completa è stata ottenuta dopo due mesi di trattamento. Il tipo 4 è stato monitorato esclusivamente da un chirurgo ortopedico per un trattamento specialistico. CONCLUSIONI: Una volta effettuata l'indagine ecografica da operatori esperti si può decidere il tipo di trattamento più adeguato. L'ottima prognosi osservata a seguito del trattamento iniziale della DDH sottolinea la necessità di eseguire uno screening dell'anca allo scopo di effettuare una diagnosi e un trattamento precoce in questa patologia.

    The coiled-coil is one of the most ubiquitous and well studied protein structural motifs. Significant effort has been devoted to dissecting subtle variations of the typical heptad repeat sequence pattern that can designate larger topological features such as relative α-helical orientation and oligomer size. Here in this paper we report the X-ray structure of a model coiled-coil peptide, HA2-Del-L2seM, which forms an unanticipated core antiparallel dimer with potential sites for discrete higher-order multimerization (trimer or tetramer). In the X-ray structure, a third, partially-ordered α-helix is weakly associated with the antiparallel dimer and analytical ultracentrifugation experiments indicate the peptide forms amore » well-defined tetramer in solution. The HA2-Del-L2seM sequence is closely related to a parent model peptide, HA2-Del, which we previously reported adopts a parallel trimer; HA2-Del-L2seM differs by only hydrophobic leucine to selenomethione mutations and thus this subtle difference is sufficient to switch both relative α-helical topology and number of α-helices participating in the coiled-coil. Comparison of the X-ray structures of HA2-Del-L2seM (reported here) with the HA2-Del parent (reported previously) reveals novel interactions involving the selenomethionine residues that promote antiparallel coiled-coil configuration and preclude parallel trimer formation. Finally, these novel atomic insights are instructive for understanding subtle features that can affect coiled-coil topology and provide additional information for design of antiparallel coiled-coils.« less

    Sommario SCOPO: L'appendicite acuta è una delle urgenze chirurgiche addominali più comuni. Se non trattata, può rapidamente progredire verso complicanze severe, quali la perforazione e la peritonite. Spesso i chirurghi optano per un intervento chirurgico precoce anche in caso di diagnosi solo probabile, con il rischio di eseguire una quota importante di appendicectomie inutili. Lo scopo dello studio è di analizzare la nostra esperienza con la diagnosi integrata clinico-ultrasonografica dell'appendicite acuta. MATERIALI E METODI: Durante il periodo gennaio 1999-dicembre 2006 1447 pazienti sono stati sottoposti a valutazione clinica, a conta leucocitaria, dosaggio della proteina C reattiva ed ecografia addominale. È stata utilizzata la tecnica ecografia di compressione graduale, con sonda ad alta frequenza. RISULTATI: È stata formulata diagnosi ecografica di appendicite acuta in 368 pazienti (25%). Ulteriori 8 pazienti sono stati operati sulla base del solo giudizio clinico. Abbiamo osservato 7 casi di falsi positivi ecografici. In 1079 (75% del totale) pazienti è stato espresso un giudizio diagnostico negativo per appendicite acuta: in 173 di essi (12%) è stata formulata una diagnosi diversa. I restanti 906 pazienti sono stati sottoposti a controllo clinico fino alla risoluzione della sintomatologia, senza alcuna complicanza. I nostri risultati hanno dimostrato una sensibilità dell'ecografia del 98%, una specificità del 99%, un valore predittivo positivo del 98% e un valore predittivo negativo del 99%. L'accuratezza diagnostica globale è stata del 99%. CONCLUSIONI: La diagnosi integrata (clinica, di laboratorio ed ecografica) dell'appendicite acuta consente una diagnosi sicura, con risparmio di risorse evitando il ricorso ad appendicectomie inutili.

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

    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.

    It is proven that the relativistic quantum fields obtained from analytic continuation of convoluted generalized (Lévy type) noise fields have positive metric, if and only if the noise is Gaussian. This follows as an easy observation from a criterion by Baumann, based on the Dell'Antonio-Robinson-Greenberg theorem, for a relativistic quantum field in positive metric to be a free field.

    We consider a pure connection action plus additional algebraic constraints that are suitable for a straightforward supergroup extension. By taking as an internal group SU(2), the action reduces to the Capovilla, Dell and Jacobson approach. By taking as an internal symmetry the supergroup OSp(2|1), and by means of the Bianchi identity and integrability conditions, the equations of motion are those that could be found from antiself-dual supergravity N = 1 with cosmological constant sector.

    Scopo. L’obiettivo primario dello studio è implementare e utilizzare uno strumento validato per misurare il fenomeno delle dimissioni difficili, che possa supportare il personale infer- mieristico nella programmazione della dimissione del paziente ricoverato nei reparti di Geria- tria e Medicina. Gli obiettivi secondari sono: - Sperimentare l’utilizzo dell’indice di BRASS - Studiare le caratteristiche della popolazione a rischio di dimissione difficile Metodo. studio osservazionale prospettico per misurare il fenomeno delle dimissioni difficili attraverso l’implementazione dell’indice di BRASS nei reparti di Geriatria e Medicina dell’Ospedale di Rovigo Ulss 18, al fine di studiare le caratteristiche della popolazione a rischio di dimissione difficile. Risultati. In un campione di 165 pazienti il 42,4% (70) era rispettivamente a rischio alto e medio di dimissione difficile, mentre il 15,2% (25) era a basso rischio. La media dei punteggi BRASS era di 18,76. Il 37,6% dei pazienti ad alto rischio erano ricoverati in Geriatria, mentre in Medicina i pazienti si concentrano maggiormente nella classe medio rischio. Conclusioni. Lo studio ha permesso di misurare il fenomeno delle dimissioni difficili classi- ficando i pazienti nei gruppi di rischio. L’analisi delle dimissioni protette ha fatto emergere la congruenza tra punteggio BRASS e caratteristiche del campione. Lo strumento non richiede tempi di compilazione lunghi, è di supporto al processo decisionale dell’infermiere perché rileva la necessità di creare un percorso strutturato sulla dimissione del paziente, in modo sistematico e programmato, evitando la dispersione di informazioni importanti al fin di garantire la continuità assistenziale.

    Sommario INTRODUZIONE: È stata valutata prospetticamente la variabilità interosservatore relativamente alla diagnosi di alterazioni focali della parete vescicale tra due operatori con diverso livello di esperienza. MATERIALI E METODI: Due operatori con diverso livello di esperienza in ecografia hanno esaminato indipendentemente nella stessa sessione 87 pazienti consecutivi (età media 68 anni; range 33–80; 75 maschi; 15 donne) sottoposti successivamente a cistoscopia entro 1–2 giorni. Prima dell’inizio dello studio la metodologia di studio è stata standardizzata. Il grado di accordo sulla presenza, sede, dimensioni e numero delle alterazioni parietali della vescica è stato calcolato con il metodo della Kw. RISULTATI: Il grado più elevato di accordo (k = 1) è stato raggiunto relativamente alla presenza delle alterazioni parietali, mentre un accordo sostanziale è stato ottenuto per le dimensioni (k = 0.78), numero (k = 0.72) e sede (k = 0.62). CONCLUSIONI: In questo studio la differenza di esperienza tra due operatori non è emersa nella diagnostica delle alterazioni parietali della vescica anche in ragione di una metodologia standardizzata di studio.

    Agricultural pharmaceuticals are a major environmental concern because of their hazardous effects on human and wildlife. This study analyzed phospholipid ester-linked fatty acids (PLFAs) and quinones to investigate the effects of a steroid (17beta-estradiol) and agricultural antibiotics (chlortetracycline and tylosin) on soil microbes in the laboratory. Two different types of soil were used: Sequatchie loam (0.8% organic matter) and LaDelle silt loam (9.2% organic matter). The soils were spiked with 17beta-estradiol and antibiotics, alone or in combination. In Sequatchie loam, 17beta-estradiol significantly increased the microbial biomass, especially the biomarkers for beta proteobacteria (16:1omega7c, 18:1omega7c, Cy17:0, and UQ-8). The coexistence of antibiotics decreased the stimulatory effect of 17beta-estradiol on the microbial community. In LaDelle silt loam, there were no significant differences in total microbial biomass and their microbial community structure among the treatments. Overall, 17beta-estradiol changed the microbial community of soil and the presence of antibiotics nullified the effect of 17beta-estradiol. However, the effects of 17beta-estradiol and antibiotics on soil microbes were sensitive to the soil properties, as seen in the LaDelle silt loam.

    Introduzione: La competenza è un elemento fondamentale quando si misura la capacità di infer- mieri o studenti di fornire assistenza infermieristica, ma non vi è consenso su ciò che realmente sia la competenza. Questo studio si propone di indagare i significati e i modelli di competenza infermieristica. Metodo: L’overview delle revisioni della letteratura e delle concept analysis è stata effettuata attraverso una ricerca su Pubmed, Cinahl e PsychINFO dal gennaio 2005 a settembre 2014, che includeva parole chiave come: Modello di competenza; Competenza professionale; Competenza infermieristica; Competenza. Risultati: Sono stati inclusi un totale di 14 articoli, provenienti dalla letteratura infermieristica sia in ambito formativo che clinico. È stato possibile individuare alcuni temi comuni negli arti- coli inclusi: la descrizione dei determinanti di competenza; la confusione intorno al concetto di competenza; la carenza nella valutazione delle competenze; la carenza nell’operazionalizzare il concetto di competenza. Conclusioni: I risultati forniscono una panoramica che, arricchita dalla letteratura proveniente dagli studi organizzativi, costituiscono la base concettuale di un modello integrato di compe- tenza infermieristica. Ulteriore ricerca empirica è necessaria per verificare le assunzioni teoriche.

  4. 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

    The galaxy cluster Abell 781 West has been viewed as a challenge to weak gravitational lensing mass calibration, as Cook & dell'Antonio found that the weak lensing signal-to-noise ratio in three independent sets of observations was consistently lower than expected from mass models based on X-ray and dynamical measurements. We correct some errors in statistical inference in Cook & dell'Antonio and show that their own results agree well with the dynamical mass and exhibit at most 2.2-2.9σ low compared to the X-ray mass, similar to the tension between the dynamical and X-ray masses. Replacing their simple magnitude cut with weights based on source photometric redshifts eliminates the tension between lensing and X-ray masses; in this case the weak lensing mass estimate is actually higher than, but still in agreement with, the dynamical estimate. A comparison of lensing analyses with and without photometric redshifts shows that a 1-2σ chance alignment of low-redshift sources lowers the signal-to-noise ratio observed by all previous studies which used magnitude cuts rather than photometric redshifts. The fluctuation is unexceptional, but appeared to be highly significant in Cook & dell'Antonio due to the errors in statistical interpretation.

  6. Multiscale Simulations of Polymers Close to (Metal) Surfaces

    2004-03-01

    We present a multi scale coarse-graining scheme for efficient molecular dynamics simulations of polymers. The approach is applied to a model system of bisphenol-A-polycarbonate (BPA-PC) liquids in contact with a (111) nickel surface. For bulk properties a suitably coarse grained bead spring model is simulated by molecular dynamics (MD) methods with model parameters directly derived from quantum chemical calculations. The surface interactions are parameterized and incorporated by extensive quantum mechanical density functional calculations using the Car-Parrinello approach. We find selective adsorption of different constituents of the PC monomer. Close to the surface this leads to a strong variation of the melt structure due to different end groups. Extensions to other systems and to surfaces with defects will shortly be discussed as well. This work was supported by the Bundesministerium für Bildung und Forschung (the German Federal Ministry of Education and Research), grant No.03 N 6015 on materials simulations.

    Gli obbiettivi di questo studio sono stati: 1) lo studio della variabilità delle dimensioni cocleari in relazione all'età e al grado di ipoacusia; 2) calcolare la lunghezza dell'elettrodo dell'impianto cocleare richiesta per ottenere l'angolo ideale d'inserzione profonda di 270°. Per raccogliere i dati riguardanti le ossa temporali sono stati inclusi nello studio 241 pazienti (482 ossa temporali) che hanno ricevuto una Tomografia Computerizzata a alta risoluzione (HRCT) dell'orecchio nel nostro Policlinico Universitario tra il 2003 e il 2008; i pazienti sono stati divisi in 3 Gruppi: 97 (194 orecchie) aventi una ipoacusia neurosensoriale severa o profonda bilaterale (Gruppo A), 70 (140 orecchie) aventi una ipoacusia neurosensoriale moderata bilaterale (Gruppo B), 74 pazienti (148 orecchie) senza ipoacusia neurosensoriale o mista (gruppo C). In ciascuno dei 3 gruppi, sono stati identificati 5 sottogruppi in base all'età: 1) sottogruppo 1: soggetti ≤ 5 anni, 2) sottogruppo 2: soggetti da 6 a 10 anni; 3) sottogruppo 3: pazienti da 11 a 15 anni, 4) sottogruppo 4: pazienti da 16 a 20 anni, 5) sottogruppo 5: soggetti >; 20 anni. Sono stati misurati la lunghezza della coclea (L), l'altezza della coclea (H), il diametro del lume del giro basale (BTLD) e il Volume della coclea (V). Il Test di Mann-Whitney è stato utilizzato per verificare l'ipotesi alternativa che a livello di queste dimensioni esiste una differenza statisticamente significativa tra i differenti gruppi e sottogruppi. La seguente equazione è stata adottata per calcolare la Lunghezza di un elettrodo rettilineo che segue la parete esterna della scala timpani necessaria per ottenere l'angolo ideale di inserzione profonda di 270° (LIC): [Formula: see text]. Secondo i nostri risultati alla nascita la coclea è completamente sviluppata e ha già raggiunto le dimensioni dell'adulto. Il Grado di ipoacusia non influenza la Lunghezza (L) e il Volume (V) della coclea, mentre può influenzare la sua altezza (H

    Si intende qui descrivere il sistema di sorveglianza sugli effetti sulla salute (SpoTT) dell'inquinamento ambientale nelle aree circostanti l'inceneritore di Torino. SPoTT ha 3 linee di attività: 1. monitoraggio epidemiologico degli effetti a breve termine attraverso analisi temporali e misura della correlazione tra livelli giornalieri di emissioni dell'impianto e andamento degli eventi individuati dagli archivi dei dimessi (SDO), di pronto soccorso e di mortalità; sono coinvolti coloro che nel 2013-2018 risiedevano nell'area di ricaduta delle emissioni; 2. sorveglianza epidemiologica degli effetti a lungo termine, stimando tassi standardizzati di mortalità e morbosità; a ogni soggetto è attribuito il valore stimato di esposizione cumulato nel tempo caratteristico della residenza anagrafica; le informazioni sulla salute sono reperite dagli archivi SDO, di mortalità e dai certificati di assistenza al parto; sono studiati due decenni pre-post l'avvio dell'impianto: 2003-2012 e 2013-2022; 3. monitoraggio biologico con misurazione pre-post di metalli, PCDD/F, PCB, OH-IPA; sono coinvolti 196 residenti esposti e 196 di controllo di 35-69 anni, campionati a caso dalle anagrafi comunali; sono effettuate misure di funzionalità endocrina e respiratoria, pressione arteriosa, rischio cardiovascolare; l'esposizione cumulativa sarà stimata per ciascuna persona campionata integrando l'indirizzo di residenza, il tempo di permanenza in ciascun indirizzo e i dati ricavati dai modelli di ricaduta; sarà costituita una biobanca per future indagini di laboratorio; sono coinvolti anche 20 allevatori e i lavoratori dell'impianto. Una quarta linea di attività, non descritta in questo articolo, riguarda il monitoraggio della salute dei lavoratori addetti all'impianto. SPoTT è il primo studio in Italia su inceneritori e salute che adotta un disegno di studio longitudinale di adeguata potenza sia per i residenti sia per i lavoratori. I primi risultati sono attesi nel corso del 2016.

    Sommario INTRODUZIONE: Valutare l'impatto diagnostico della Isterosonografia Tridimensionale (ISG 3D) nello studio della cavità uterina in donne con sanguinamento anomalo (SUA) rispetto all'ecografia transvaginale (ETV) e all'isterosonografia bidimensionale (ISG 2D), particolarmente per l'identificazione di neoformazioni a sviluppo endocavitario della superficie endometriale e della parete uterina. MATERIALI E METODI: Ventiquattro pazienti affette da SUA sono state incluse nello studio. Ciascuna di esse é stata sottoposta ad ETV, ISG e ISG 3D durante la medesima seduta. Le acquisizioni 3D sono state ottenute con tecnica free-hand in fase di massima replezione idrica della cavità. Tutte le pazienti sono state valutate con isteroscopia entro 10 giorni dall'ecografia. Considerando l'esame isteroscopico come reference standard, sono stati calcolati i valori di sensibilità, specificità, valore predittivo positivo (VPP), valore predittivo negativo (VPN) ed accuratezza delle tre metodiche. RISULTATI: L'isteroscopia ha dimostrato la presenza di lesioni endocavitarie in 21/24 pazienti (87,5%). Nelle restanti pazienti l'esame isteroscopico è risultato negativo. ETV, ISG 2D ed ISG 3D hanno mostrato rispettivamente sensibilità del 76% (16/21), 90% (19/21), 100% (21/21); specificità del 100% (3/3), 100% (19/19), 100% (21/21); VPP del 100%, 100%, 100%; VPN del 37%, 60%, 100%; accuratezza 76%, 90%, 100%. L'ISG 3D ha consentito una completa identificazione dei rapporti delle lesioni con la cavità uterina e con la parete endometriale. CONCLUSIONI: L'ISG 3D è una metodica con maggiore sensibilità nella definizione delle lesioni della cavità uterina rispetto all'ISG 2D ed all'ETV. Se questi dati preliminari saranno confermati da studi piú ampi, ISG 3D potrebbe essere proposta come alternativa all'isteroscopia eseguita a soli fini diagnostici.

    Il trattamento dell’iperparatiroidismo primario è quasi esclusivamente chirurgico e consiste nell’esplorazione sistematica delle quattro ghiandole con asportazione di quella( e) patologica(e). Le più moderne tecniche di diagnosi (ecotomografia, scintigrafia 99 mTc sestamibi), migliorando le possibilità di individuare la ghiandola responsabile della malattia, consentono l’esecuzione di tecniche miniinvasive quando vi è concordanza tra i risultati delle due tecniche, ma la sensibilità di tali indagini è inficiata dalle ectopie ghiandolari, da paratiroidi intratiroidee, da malattia multighiandolare o dalla contemporanea presenza di malattie tiroidee. Il presente studio illustra una nuova tecnica di imaging scintigrafico intraoperatorio ed indaga sulla sua possibilità di migliorare la localizzazione intraoperatoria della paratiroide patologica. A tal fine, 5 pazienti sono state sottoposte a tale metodica, tutte trattate con paratiroidectomia previa esplorazione completa delle quattro ghiandole con tecnica tradizionale, con monitoraggio intraoperatorio del paratormone. Alla tecnica convenzionale è stato aggiunto l’impiego della gamma camera intraoperatoria. Abbiamo valutato la concordanza dei risultati di tale esame con i dati dell’esplorazione chirurgica e con il dosaggio intraoperatorio del paratormone. In tutte e 5 le pazienti si è osservata una perfetta concordanza tra la localizzazione della ghiandola patologica con la scintigrafia intraoperatoria e l’esplorazione chirurgica, ed il dosaggio intraoperatorio del paratormone ha confermato i dati. Anche il follow-up ad un mese ha confermato l’eradicazione della malattia. La gamma camera intraoperatoria sembra quindi poter migliorare le possibilità di localizzazione della ghiandola responsabile dell’iperparati-roidismo primario, favorendo l’impiego di tecniche mini-invasive e migliorando i risultati dinanzi a casi “difficili”.

    In 2011 four ice cores were extracted from the summit of Alto dell'Ortles (3859 m), the highest glacier of South Tyrol in the Italian Alps. This drilling site is located only 37 km southwest from where the Tyrolean Iceman, ˜ 5.3 kyrs old, was discovered emerging from the ablating ice field of Tisenjoch (3210 m, near the Italian-Austrian border) in 1991. The excellent preservation of this mummy suggested that the Tyrolean Iceman was continuously embedded in prehistoric ice and that additional ancient ice was likely preserved elsewhere in South Tyrol. Dating of the ice cores from Alto dell'Ortles based on 210Pb, tritium, beta activity and 14C determinations, combined with an empirical model (COPRA), provides evidence for a chronologically ordered ice stratigraphy from the modern glacier surface down to the bottom ice layers with an age of ˜ 7 kyrs, which confirms the hypothesis. Our results indicate that the drilling site has continuously been glaciated on frozen bedrock since ˜ 7 kyrs BP. Absence of older ice on the highest glacier of South Tyrol is consistent with the removal of basal ice from bedrock during the Northern Hemisphere Climatic Optimum (6-9 kyrs BP), the warmest interval in the European Alps during the Holocene. Borehole inclinometric measurements of the current glacier flow combined with surface ground penetration radar (GPR) measurements indicate that, due to the sustained atmospheric warming since the 1980s, an acceleration of the glacier Alto dell'Ortles flow has just recently begun. Given the stratigraphic-chronological continuity of the Mt. Ortles cores over millennia, it can be argued that this behaviour has been unprecedented at this location since the Northern Hemisphere Climatic Optimum.

  12. 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.

    Sommario INTRODUZIONE: La malattia di Niemann-Pick (NPD) tipo A e B è una patologia da accumulo di lipidi. Il tipo A è un disordine fatale dell'infanzia. Il tipo B è una forma non-neuronopatica ossevata sia nei bambini che negli adulti con possibile riscontro di epatomegalia e/o splenomegalia (nodulare) durante un esame ecografico. Il tipo C dipende da un difetto nel trasporto del colesterolo. METODI: Una donna di 21 anni si è presentata al Pronto Soccorso con febbre, faringodinia e dolore al quadrante addominale superiore sinistro. Gli esami ematochimici hanno evidenziato anemia, piastrinopenia, aumento delle AST, ALT, GGT, FA, LDH trigliceridi, colesterolo totale, e ridotto HDL. La PCR per CMV ed EBV era negativa. La radiografia del torace era negativa. L'ecografia transaddominale ha rilevato splenomegalia (>22 cm long axis) con una lesione ipoecogena irregolare subcapsulare al polo superiore compatibile con infarto splenico e la presenza di multiple lesioni nodulari iperecogene con diametro da 1 cm fino a 5. RISULTATI: È stata quindi eseguita una ecografia con mezzo di contrasto con SonoVue (Bracco) che ha confermato la presenza di un infarto splenico. Le lesioni nodulari mostravano un enhancement in fase arteriosa con wash out in fase parenchimatosa tardiva. La F-FDG-PET ha mostrato un uptake nodulare splenico. Nel sospetto di un processo linfoproliferativo è stata eseguita una splenectomia. La diagnosi è stata di NPD tipo B con infarto splenico e le lesioni nodulari sono risulate essere emangiomi. DISCUSSIONE: Concludendo, la CEUS ha confermato la diagnosi e l'estenzione dell'infarto splenico, ma l'enhancement nodulare atipico supportato dalle immagini F-FDG-PET è stato fuorviante, suggerendo l'ipotesi di lesioni linfomatose.

    L’appendicite è la patologia che più comunemente richiede un intervento chirurgico in emergenza, e l’appendicectomia è il procedimento chirurgico più commune in tutto il mondo, importante in quanto rappresenta un trattamento efficace. Il nostro scopo è stato quello di determinare le variazioni stagionali dell’appendicite nella nostra regione e di indentificare le differenze demografiche e regionali, e per questo abbiamo analizzato retrospettivamente I dati dei pazienti ricoverati nell’ospedale universitario Afyon Kocatepe e nell’ospedale statale Sivrihisar State tra il 2003 ed il 2012, cioè 839 pazienti. L’età media di tutti i pazienti era di 33 ± 14.7 anni, e la maggior frequenza dell’appendicite acuta è risultata in autunno e nella primavera (P > 0.05). Non si sono osservate differenze sigfnificative stagionali nell’ospedale universitario Afyon Kocatepe, mentre l’appendicite si è manifestata più frequentemente in autunno che non in inverno nell’ospedale statale Sivrihisar (P < 0.05). non c’è stata nessuna relazione con la temperatura media mensile, l’umidità, l’entità delle precipitazioni e la frequenza dell’appendicite (P > 0.05). In conclusion, sebbene l’appendicite presenta una variazione stagionale, altri fattori embientali e l’impatto delle abitudini alimentari non vanno ignorate. L’etiologia dell’appendicite è comunque.multifattoriale, e nei futuri studi multiparametrici nell’intero territorio nazionale potrebbero evidenziarsi delle etiologie territorio-specifiche di questa patologia.

    Epidermal growth factor receptor (EGFR) is one of the targeted molecular markers in many cancers including lung malignancies. Gefitinib and erlotinib are two available therapeutics that act as specific inhibitors of tyrosine kinase (TK) domains. We performed a case-control study with formalin-fixed paraffin-embedded tissue blocks (FFPE) from tissue biopsies of 167 non-small cell lung carcinoma (NSCLC) patients and 167 healthy controls. The tissue biopsies were studied for mutations in exons 18-21 of the EGFR gene. This study was performed using PCR followed by DNA sequencing. We identified 63 mutations in 33 men and 30 women. Mutations were detected in exon 19 (delE746-A750, delE746-T751, delL747-E749, delL747-P753, delL747-T751) in 32 patients, exon 20 (S786I, T790M) in 16, and exon 21 (L858R) in 15. No mutations were observed in exon 18. The 63 patients with EFGR mutations were considered for upfront therapy with oral tyrosine kinase inhibitor (TKI) drugs and have responded well to therapy over the last 15 months. The control patients had no mutations in any of the exons studied. The advent of EGFR TKI therapy has provided a powerful new treatment modality for patients diagnosed with NSCLC. The study emphasizes the frequency of EGFR mutations in NSCLC patients and its role as an important predictive marker for response to oral TKI in the south Indian population.

    Sommario INTRODUZIONE: La ricchezza della componente vascolare dei tumori ginecologici influenza le caratteristiche dell'imaging diretto, utilizzando metodiche che evidenziano la componente macrovascolare delle lesioni (color e power Doppler), e di quello indiretto, mediante somministrazione di mezzi di contrasto (MdC) per lo studio del microcircolo e della perfusione interstiziale. Lo scopo di questo lavoro è di valutare l'aggiunta di informazioni diagnostiche fornite dalla valutazione ecografica con MdC nello studio delle lesioni ovariche. MATERIALI E METODI: Abbiamo valutato 72 lesioni annessiali in 61 pazienti con lesioni ovariche di incerta interpretazione mediante somministrazione di 4,8 ml di MdC ecoamplificatore di II generazione. Per ogni lesione, abbiamo valutato la morfologia basale, quella contrastografica e le curve intensità/tempo. RISULTATI: La valutazione post-contrasto confrontata con la basale non ha apportato informazioni aggiuntive morfovascolari in 8 pazienti (13,1%); in 38 pazienti (62,3%) ha apportato informazioni senza modifiche del comportamento clinico; in 15 soggetti (24,6%) ha apportato elementi che hanno modificato il comportamento clinico. Le lesioni maligne presentavano valori di tempo massimo di enhancement significativamente minori (11,9 ± 3,1 s vs 19,8 ± 4,0 s p < 0,01) e intensità di picco massimo significativamente maggiore (24,7 ± 4,2 dB vs 17,8 ± 3,3 dB p < 0,01) rispetto alle lesioni benigne. CONCLUSIONI: La CEUS consente di migliorare la confidenza diagnostica nelle lesioni liquide corpuscolate in cui l'indagine convenzionale non risulta dirimente, proponendosi nella diagnosi differenziale di un limitato numero di lesioni complesse, in alternativa a TC ed RM. Le informazioni ottenute influenzano tuttavia il successivo iter diagnostico e terapeutico in una limitata percentuale di casi (24,6%).

    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.

    Sommario INTRODUZIONE: La fisiologia articolare dell’articolazione temporo-mandibolare (ATM) può essere esaminata sia dal punto di vista clinico che strumentale. La diagnostica per immagini ha da tempo contribuito con la risonanza magnetica (RM) e anche con la radiografia (Rx) e la tomografia computerizzata (TC) all’analisi della morfologia dei capi articolari e della cinetica condilare. L’esame duplex-ecodoppler è una metodica di largo impiego nello studio delle strutture in movimento in particolar modo a livello delle strutture del sistema vascolare. MATERIALI E METODI: È stata utilizzata un’apparecchiatura Toshiba APLIO SSA-770A, con l’uso di tecnica duplex-ecodoppler multi display, che consente la visualizzazione contemporanea dell’immagine ecografica e dei segnali Doppler utilizzando una sonda lineare del tipo phased array con cristalli trasduttori funzionanti ad una frequenza fondamentale di 6 MHz per gli spettri Doppler pulsati e 7.5 MHz per l’imaging ecografico. Sono stati esaminati nel Dipartimento di Scienze Radiologiche, Oncologiche e Anatomo-patologiche dell’Università “Sapienza” di Roma, 30 pazienti del reparto di Ortognatodonzia dell’Istituto di Odontoiatria della stessa Università. RISULTATI: Nei pazienti normali si è ottenuta un’alternanza regolare degli spettri Doppler, mentre nei soggetti con disfunzioni del complesso condilo-meniscale, si è persa la regolarità della sommatoria degli spettri di Fourier, con altezze incostanti in relazione a spostamenti irregolari del complesso condilo-meniscale. CONCLUSIONI: L’esame ecodoppler si è dimostrato, in tutti i pazienti, capace di discriminare quelli normali dai patologici e tra questi ultimi ha permesso di identificare gli aspetti più significativi delle patologie disfunzionali.

    Introduzione: L’ospedalizzazione si configura come una condizione nella quale l’individuo cessa le sue normali attività quotidiane per essere preso in carico da una struttura ospedaliera, allo scopo di risolvere un problema di salute. Il personale sanitario ha la responsabilità di rendere l’evento “ricovero” il meno traumatico possibile, considerando l’accoglienza un momento cruciale, un “biglietto da visita” per la struttura, che condizionerà in buona parte l’esito di gradimento della degenza. Obiettivo: Esplorare l’esperienza di ricovero degli utenti intervistati, per delineare i temi princi- pali che influenzano la qualità assistenziale fornita nel contesto di due ospedali romani e, in rela- zione alle aree tematiche riscontrate, rilevare le criticità prevalenti. Metodo: raccolta dati attraverso somministrazione di questionari semi-strutturati, successivo approccio fenomenologico focalizzato all’analisi dei vissuti esperienziali delle persone reclutate per estrarne i temi di significato con tecnica induttiva di Van Kaam. Risultati: Dalle interviste effettuate aventi per oggetto il vissuto dell’utente rispetto all’esperienza dell’ospedalizzazione, sono stati delineati 4 elementi essenziali che condizionano la qualità dell’as- sistenza fornita e, in questi, rilevate le criticità più evidenti; si è evidenziata pertanto un’asimme- tria relazionale e comunicativa tra operatore sanitario e utente ed inoltre una scarsa consapevo- lezza del personale sanitario riguardo l’importanza del “primacy effect”, quale elemento prelimi- nare per rafforzare le successive percezioni positive delle cure ospedaliere. Conclusioni: Alla luce dei risultati emersi, lo studio può fornire interessanti spunti ed indica- zioni a tutti coloro che, a diverso titolo, operano nell’ambito delle professioni sanitarie.

    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

La microanalyse a l'expérience, which appeard in 1996 under the direction of Jacques Revel, was translated in Italy in 2006 by the Viella editions under the title Giochi di scala. La microstoria alla prova dell'esperienza. This occasion seemed propicious for a historiographic and epistemological return to the microhistorical experience between France and Italy. It had to do with cross reperencing the reflections of a French historian and those of an Italian philosopher to seek to place in evidence, from a distance, the theoretical presuppositions of microhistory, and to measure the displacements undergone.

  3. The Iconography of Chaos in a Renaissance Painting

    Zausner, Tobi

    Titian's Presentation of the Virgin to the Temple (1534-38) is a large oil painting on canvas (11' x 25'4"), hanging in the Gallerie dell' Accademiain Venice. Underneath its overt Christian imagery, the painting appears to have a hidden humanist symbolism encoding self-transformation through initiation. Humanist disciplines such as Neoplatonism, the ancient mystery religions, Graeco-Roman paganism, and the Jewish Kaballah are suggested in Titian's painting. Certain figures and groups of figures appear to symbolize the underworld and the period of chaos necessary for transformation. Additional evidence for the chaos in self-transformation is found in the painting's geometry and in its astronomical references.

  9. Ambienti Circumstellari ed Interstellari di Supernovae di vario Tipo ed Applicazioni Astrofisiche

    NASA Astrophysics Data System (ADS)

    Boffi, Francesca R.

    Nella presente tesi vengono studiati gli ambienti circumstellari ed interstellari di supernovae (anche SNe; singolare SN) di vario tipo. In particolare si descrivono alcune applicazioni astrofisiche, relative a questi ambienti, che permettono di desumere informazioni sui sistemi stellari progenitori delle supernovae o di determinare le distanze a tali oggetti. L' emissione radio da supernovae, prodotta nell' ambiente circumstellare ad opera dell'interazione idrodinamica del gas di SN con l' ambiente circostante, puo' essere impiegata come mezzo di indagine del sistema di pre-supernova. In particolare si e' introdotta l'idea che tale emissione possa essere impiegata nel caso delle SNe di tipo Ia come test dei sistemi progenitori di tipo simbiotico. Il test e' stato effettuato sulla SN 1986G, per la quale avevamo ottenuto limiti superiori a lunghezze d'onda radio. Nel caso che un sistema simbiotico sia responsabile di una SN Ia, l'interazione tra l' ejecta e una shell circumstellare origina, in un'epoca molto prossima al massimo di luce, un'emissione radio rivelabile con strumenti tipo Very Large Array. Inoltre l'emissione radio fornisce informazioni circa gli stadi di pre-supernova nel caso di altri tipi di supernova. In questo lavoro di tesi vengono presentati i risultati ottenuti nel caso delle SNe di tipo II 1984E e 1986E. Queste due SNe non mostrano emissione radio: la prima, in prossimita del massimo ottico, stava interagendo con una shell circumstellare prodotta da un episodio di perdita di massa di breve durata in fase di pre-supernova; la seconda, invece e' la prima SN ``vecchia'' ad essere rivelata nell' ottico ma non nel radio (l' oggetto non ha ancora iniziato la fase di supernova remnant ed emette radiazione ottica prodotta ancora per interazione circumstellare). In ambiente circum-interstellare, gli echi di luce, prodotti dallo scattering della luce della supernova ad opera della polvere presente, possono essere utilizzati per determinare le distanze

    Excavation of the Etruscan Necropolis dell'Osteria near Vulci (VI Century b.c.) brought to light in Tomb 2 a bronze plumpekanne. According to preliminary X-ray observation, an unusually thick deposit of organic nature lay at its bottom. Numerous samples of the residue were investigated using microFTIR and diffuse reflectance FTIR spectroscopy. For comparative purposes similar analyses were performed on samples of resins mentioned in classical sources. Spectroscopic results identify the residue as mastic or incense, both triterpenic resins. The former seems to be preferred since, according to classical sources, it was used as must additive.

  20. The multidimensional inventory of dissociation (MID): A comprehensive measure of pathological dissociation.

    PubMed

    Dell, Paul F

    2006-01-01

    This article describes the development and validation of the Multidimensional Inventory of Dissociation (MID). The MID is a 218-item, self-administered, multiscale instrument that comprehensively assesses the phenomenological domain of pathological dissociation and diagnoses the dissociative disorders. The MID measures 14 major facets of pathological dissociation; it has 23 dissociation diagnostic scales that simultaneously operationalize (1) the subjective/ phenomenological domain of pathological dissociation and (2) the hypothesized dissociative symptoms of dissociative identity disorder (Dell, 2001a). The MID was designed for clinical research and for diagnostic assessment of patients who present with a mixture of dissociative, posttraumatic, and borderline symptoms. The MID demonstrated internal reliability, temporal stability, convergent validity, discriminant validity, and construct validity. The MID also exhibited incremental validity over the Dissociative Experiences Scale (DES) by predicting an additional 18% of the variance in weighted abuse scores on the Traumatic Experiences Questionnaire (TEQ). Confirmatory factor analysis (CFA) did not support a one-factor model of the MID's clinical scales (i.e., the 14 facets and the 23 diagnostic symptoms). In contrast, however, CFA of the MID's factor scales (Dell & Lawson, 2005) has strongly supported a one-factor model. It was concluded that both the MID's 168 dissociation items and the construct of pathological dissociation have a second-order, unifactorial structure.

    The archaeological investigation carried out from 2003 in the Castellaccio locality, undertaken to realize the "Europarco" town planning, brought to light a part ofa road dated to the roman age, identified as the ancient via Laurentina. The road is oriented N/NE-S/SW, is 400 metres long and cross with a bridge the Fosso dell'Acqua Acetosa. Two buildings run alongside this trait of the ancient Laurentina: one can be interpreted as a rural structure, the other one as a mansio. A sidestreet starts from the final edge of the recovered road and run toward East, along the original route of the Fosso dell'Acqua Acetosa Ostiense: the historians recognized it as a boundary of the Ager Romanus Antiquus nearby the VI mile, place of the god Terminus sanctuary. A necropolis made up ofmore than 130 graves, mainly inhumations, was found in the southern part of the crossroads, near the oriental side of the Laurentina. The stratigraphical analysis and the examination of the grave goods allowed the characterization of three period of funerary use of the necropolis, between the middle republican age and the first two century of the Empire. In all three period stand out graves of infants and women, of extreme interest from the ritual point of view and supplied with rich grave goods.

    Una delle principali e più temute complicanze della resezione anteriore di retto è stata ed è la deiscenza anastomotica. Solitamente, sia essa una scelta di principio od a discrezione del chirurgo operatore, viene confezionata una ileostomia laterale di sicurezza con lo scopo di prevenire tale circostanza. Scopo di tale studio è stato quello di investigare circa la utilità della stomia laterale di sicurezza quale strumento di prevenzione della deiscenza anastomotica, mettendo a paragone il decorso post-operatorio dei paziente con e senza stomia laterale. Le evidenze hanno portato alla conclusione che il confezionamento della stomia laterale di sicurezza è fattore di protezione non tanto dell’evento deiscenza anastomotica in senso stretto, quanto delle complicanze e della evoluzione clinica della stessa, vedasi ad esempio tasso di ricorrenza di deiscenza/quadro clinico in corso di deiscenza/ tempi di degenza, pur rendendosi necessario sottolineare l’assenza di significatività statistica nel tasso di mortalità nei due gruppi in studio. Cosi detto appare dunque sinottico affermare che il confezionamento di ileostomia laterale di sicurezza in corso di resezione anteriore di retto non determina una diretta azione sull’evento “deiscenza anastomotica” né “morte”, purtuttavia modifica certamente in positivo il decorso clinico ed evolutivo dell’evento “deiscenza anastomotica”.

    Oggetto di questa pubblicazione è la descrizione di una nuova tecnica chirurgica per la riparazione videolaparoscopica di laparoceli ed ernie della parete addominale anteriore. Tale tecnica è strettamente dipendente dall’utilizzo di un nuovo strumento pneumatico per il posizionamento della protesi. Attualmente esistono in commercio svariati tipi di protesi intraperitoneali con valide caratteristiche strutturali. Tuttavia lo scoglio concettuale rimane sui metodi e sui mezzi di fissaggio delle protesi. I mezzi meccanici di qualsiasi conformazione per il fatto stesso di essere dei mezzi meccanici (spirali metalliche ancorette e viti) espongono al pericolo di danno iatrogeno le strutture vascolari nervose che possono incontrare nel loro percorso. La nuova tecnica proposta mira alla perfetta distensione delle protesi per utilizzo intraperitoneale ed ai loro ottimale fissaggio con adesivo chirurgico in condizioni di sicurezza per le strutture circostanti. Tale tecnica è stata eseguita su cadavere di suino* con protesi intraperitoneali di poliestere-gel-collageno e cyanoacrylate come adesivo chirurgico ma non è esclusa la fattibilità con altri tipi di colle, di protesi, protesi auto-adesive già esistenti in commercio o che potrebbero essere appositamente prodotte.

    RIASSUNTO. Scopo. Il DSM-5 presenta delle modifiche nei criteri diagnostici per il gioco d'azzardo patologico, rispetto alla precedente edizione del manuale; è pertanto necessario sviluppare nuovi strumenti diagnostici. Questo studio ha valutato le caratteristiche psicometriche del Gambling Disorder Screening Questionnaire (GDSQ), un questionario sviluppato per l'autosomministrazione, basato sui criteri diagnostici del DSM-IV e del DSM-5 per il gioco d'azzardo patologico, misurandone la validità e la consistenza interna e sottoponendo il questionario all'analisi delle componenti principali. Metodi. 71 pazienti reclutati da un ambulatorio dedicato al gioco d'azzardo patologico e 70 controlli sono stati valutati con il GDSQ, con il South Oaks Gambling Screen (SOGS) e con valutazione psichiatrica. Risultati. Il test ha mostrato una buona sensibilità, specificità, consistenza interna, correlazione con il SOGS. L'esclusione del criterio degli atti illeciti e l'abbassamento del punteggio di cut-off a quattro criteri positivi, come suggerito dal DSM-5, migliora la sensibilità e consistenza interna del test. Discussione e conclusioni. Il GDSQ può essere considerato un utile test di screening per il gioco d'azzardo patologico. Inoltre, questo studio conferma il miglioramento nell'accuratezza diagnostica dei criteri elencati nella quinta edizione del Manuale Diagnostico e Statistico dei Disturbi Mentali rispetto alla precedente edizione.

    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 purpose of this study was to describe how Minimum Data Set (MDS) Coordinators' relationship patterns influence nursing home care processes. The MDS Coordinator potentially interacts with staff across the nursing home to coordinate care processes of resident assessment and care planning. We know little about how MDS Coordinators enact this role or to what extent they may influence particular care processes beyond paper compliance. Guided by complexity science and using two nursing home case studies as examples (pseudonyms Sweet Dell and Safe Harbor), we describe MDS Coordinators' relationship patterns by assessing the extent to which they used and fostered the relationship parameters of good connections, new information flow, and cognitive diversity in their work. Sweet Dell MDS Coordinators fostered new information flow, good connections, and cognitive diversity, which positively influenced assessment and care planning. In contrast, Safe Harbor MDS Coordinators did little to foster good connections, information flow, or cognitive diversity with little influence on care processes. This study revealed that MDS Coordinators are an important new source of capacity for the nursing home industry to improve quality of care. Findings suggest ways to enhance this capacity.

    La perforazione del setto nasale ha cause molteplici: traumatiche, iatrogene, infettive, degenerative, da abuso di vasocostrittori, da uso di cocaina e di recente anche da chemioterapici antineoplastici. Le perforazioni sono altresì classificate in funzione delle dimensioni e della tipologia del deficit cartilagineo o osteocartilagineo e della sede anteriore, mediana e posteriore. Molteplici tecniche di riparazione chirurgica del danno sono state proposte nel tempo e vengono riassunte nel presente lavoro per tipologia di approccio; i risultati conseguiti, sono soddisfacenti per le perforazioni di piccole e medie dimensioni, ma nelle grandi perforazioni non garantiscono sempre la permanente obliterazione del difetto. Spesso si rende necessario l'utilizzo di tessuti prelevati all'interno delle fosse nasali come i turbinati o il prelievo di cartilagine da altre sedi donatrici come l'orecchio o la costa; le varie tecniche vengono illustrate alla luce della più recente letteratura. Gli Autori hanno valutato i pazienti osservati negli ultimi 8 anni e i risultati chirurgici conseguiti in particolare considerando, gli approcci chirurgici effettuati in approccio aperto o chiuso, endoscopico ed i materiali impiegati. Gli autori propongono tra le varie tecniche impiegate in questa serie di pazienti, una tecnica innovativa utilizzabile con successo in molti dei casi considerati di perforazione settale iatrogena che prevede l'utilizzo del gibbo osteocartilagineo quale sede donatrice, nonché la rinosettoplastica riduttiva quale scelta mirata per ottenere agevolmente lembi di scorrimento mucopericondrale e talora produrre anche un miglioramento estetico morfologico.

    L’Echinococcus spp. rappresenta il movente eziopatogenetico della malattia idatidea, patologia a carattere endemico in diverse parti del mondo, con tipica localizzazione della cisti da echinococco, prodotto del ciclo vitale del parassita, in sede polmonare od epatica. Ciononostante le localizzazioni atipiche della malattia esistono e rappresentano circa il 1,6% dei casi, la più comune delle quali certamente quella sottocutanea. I dati a disposizione circa la diagnosi ed il trattamento delle rare forme a localizzazione atipica risultano disomogenei e pochi dirimenti circa uno standard diagnostico-terapeutico da adottare. Si è voluto presentare dunque il caso di una donna di 68 anni che lamentava la comparsa di una tumefazione al terzo prossimale della coscia dx che tendeva ad incrementarsi volumetricamente nel tempo. Dopo diverse indagini cliniche, oltre che una accurata anamnesi, il sospetto di cisti idatidea è stato confermato. La patologia è stata trattata secondo uno schema terapeutico chirurgico e farmacologico ben dettagliato. La raccolta di questi dati si prefigge lo scopo di pianificare, in accordo con la letteratura scientifica e la review dei case-report esistenti, linee guida nel percorso assistenziale di questa rara manifestazione di una comune malattia.

  9. Teleportation of squeezing: Optimization using non-Gaussian resources

    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. De 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.

    By the late 2008 one of the most important pieces of the "Museo delle Antichità Egizie" in 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", 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.

    The purpose of this document is to investigate Oracle database log buffer queuing and its affect on the ability to load data using a specialized data loading system. Experiments were carried out on a Linux system using an Oracle 9.2 database. Previous experiments on a Sun 4800 running Solaris had shown that 100,000 entities per minute was an achievable rate. The question was then asked, can we do this on Linux, and where are the bottlenecks? A secondary question was also lurking, how can the loading be further scaled to handle even higher throughput requirements? Testing was conducted using a Dell PowerEdge 6650 server with four CPUs and a Dell PowerVault 220s RAID array with 14 36GB drives and 128 MB of cache. Oracle Enterprise Edition 9.2.0.4 was used for the database and Red Hat Linux Advanced Server 2.1 was used for the operating system. This document will detail the maximum observed throughputs using the same test suite that was used for the Sun tests. A detailed description of the testing performed along with an analysis of bottlenecks encountered will be made. Issues related to Oracle and Linux will also be detailed and some recommendations based on the findings.

    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.

    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).

    emergenti (LESS e NOTES), poco è riportato in letteratura. Altri robot esistono nel mondo urologico che si stanno sviluppando e miniaturizzando (nanotecnologia), questi avranno una maggiore indipendenza nell'esecuzione di alcune manovre chirurgiche. Chirurgia computer assistita Il primo realizzato è stato PAKY, da allora il laboratorio di "urobotica", diretto dall'Ing. Dan Stoianovici, ha sviluppato nuovi prototipi di robot controllati mediante TAC o risonanza magnetica. Con questa tecnologia si programma l'intervento sulla base dell'"imaging" preoperatorio ed il robot esegue autonomamente biopsie ed altri interventi. Oggi sono molti i laboratori di ingegneria-urologica che lavorano nella realizzazione di altri robot (Probot, Acubot, Mr-Bot, Pneu-Step) dedicati all'Image-Guided System (IGS). Realtà virtuale Avanzati sistemi di computer grafica affiancati alle nuove ricostruzioni tridimensionali di TAC e RM, riescono a creare filmati dell'anatomia interna dei pazienti, in particolare degli organi cavi. Con la realtà virtuale si possono assistere tutte le manovre endoscopiche, migliorando notevolmente l'accuratezza della diagnosi delle patologie urologiche. A questo punto il passaggio al "Tissue Navigation System" è automatico, usato da alcuni anni con successo da neurochirurghi e cardiochirurghi. Alcuni recenti studi vengono dalla Cleveland Clinic Fondation (I. Gill), che lo utilizza per assistere interventi di laparoscopia ed endoscopia urologica. I risultati sono entusiasmanti: precisione millimetrica nel rispetto dei margini oncologici, delle strutture neuro-vascolari e linfonodali. Questi sistemi di navigazione abbattono la lunga "learning curve" delle metodiche endoscopiche, riducendo il tempo operatorio ed il rischio di complicanze chirurgiche.

    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

We eliminate these apparent inconsistencies by deriving analytically the pdf of ΔY from that of Y , given that the latter is NLN. In our model the tail of the ΔY pdf scales with the correlation coefficient of G and thereby with lag; all other parameters of the pdf remaining unaltered with lag. We illustrate key features of our new model by way of synthetic examples. We then propose and test a methodology to estimate, accurately and efficiently, all model parameters using sample moments of both Y and ΔY . We end by exemplifying the use of our new model and method of inference by applying them to neutron porosity data from deep boreholes. References Clark, P.K.

  20. HUBBLE FINDS THOUSANDS OF GASEOUS FRAGMENTS SURROUNDING DYING STAR

    NASA Technical Reports Server (NTRS)

    2002-01-01

    Resembling a bizarre setting from a science fiction movie, dramatic images sent back by NASA's Hubble Space Telescope have surprised astronomers by uncovering thousands of gigantic tadpole-shaped objects surrounding a dying star. Dubbed 'cometary knots' because their glowing heads and gossamer tails superficially resemble comets, they are probably the result of a dying star's final outbursts. Though ground-based telescopic observations have hinted at such objects, they have not previously been seen in such abundance, say researchers. The knots were detected by Hubble astronomer C. Robert O'Dell and graduate student Kerry P. Handron of Rice University in Houston, Texas, while exploring the Helix nebula, a ring of glowing gases blown off the surface of a sunlike star late in its life. O'Dell expects the gaseous knots, which are each several billion miles across, will eventually dissipate and vanish into the cold emptiness of interstellar space. However, he speculates that if the objects contract to form permanent solid bodies, they may contribute to a fraction (less than ten percent) of the missing mass of our galaxy, simply because of their sheer abundance around a typical dying star. (This so-called dark matter is a known source of gravity that affects the motions of stars in the galaxy). The mysterious 'space pods' came into view as O'Dell used Hubble's Wide Field Planetary Camera 2 to survey the Helix nebula, located 450 light-years away in the constellation Aquarius and the closest planetary nebula to Earth -- so close that its angular size is almost half that of the full Moon. The most visible cometary knots all lie along the inner edge of the ring, at a distance of trillions of miles from the central star.

    INTRODUZIONE. L’assistenza alle persone con malattie croniche rappresenta una sfida per il benessere della popolazione e per la futura sostenibilità dei sistemi sanitari. La promozione del self-care è considerata un aspetto chiave dell’assistenza ai malati cronici. Lo scopo di questa revisione della letteratura è stato quello di esplorare: come il self-care nelle malattie croniche è stato definito dal punto di vista teorico; come il self-care può essere valutato nella pratica clinica e nella ricerca; quali associazioni esistono tra il livello di self-care e i risultati di salute dei pazienti con malattie croniche. RISULTATI. In letteratura si è riscontrata un’ampia gamma di definizioni e terminologie connesse con il self-care nelle malattie croniche. Sebbene nei diversi approcci siano stati identificati alcuni elementi comuni utili a spiegare il concetto di self-care, le variabili fisiche, cognitive, emotive e socioculturali sottese al self-care nelle malattie croniche risultano controverse e scarsamente definite. Un crescente numero di studi ha sviluppato o impiegato strumenti di valutazione del self-care validi ed affidabili per una specifica malattia cronica; tuttavia molti autori riportano la mancanza di utilizzo di strumenti di valutazione nella pratica clinica standard. Un numero limitato di studi ha mostrato delle correlazioni significative tra il self-care nelle malattie croniche e alcune misure di risultato come lo stato generale di salute, la qualità di vita e i costi dell’assistenza sanitaria. CONCLUSIONI. Favorire lo sviluppo del self-care è riconosciuto come un aspetto cruciale dell’assistenza ai malati cronici. Un’analisi più approfondita delle variabili e dei processi che influenzano il self-care potrebbe contribuire ad una più completa descrizione di questo fenomeno. La valutazione sistematica del self-care nella pratica clinica dei professionisti sanitari è fortemente raccomandata. Lo sviluppo di strumenti generali e non

    Lo scopo dello studio è stato valutare l’incidenza di complicanze correlate alla calcolosi della colecisti in pazienti in lista d’attesa per l’intervento di colecistectomia e quantificare le implicazioni economiche di quest’attesa in termini di costi sanitari relativi agli esami ematochimici, strumentali, alla degenza, all’intervento chirurgico e alle terapie somministrate. La popolazione oggetto dello studio è stata di 86 pazienti, 39 uomini e 47 donne, inseriti in lista d’attesa per intervento chirurgico di colecistectomia in un periodo compreso fra aprile 2007 e aprile 2010. Di tali pazienti sono stati raccolti dati anagrafici, la durata del tempo d’attesa, dettagli sugli accessi in PS ed eventuali ricoveri durante l’attesa, esami e terapie eseguite, il tipo di intervento chirurgico effettuato e i giorni di degenza. È stato fatto uno studio comparativo di natura economica tra tre gruppi di pazienti: A: asintomatici durante l’attesa, B: complicati ma non operati in urgenza, C: complicati e operati in regime d’urgenza. Utilizzando il tariffario regionale delle prestazioni di assistenza specialistica ambulatoriale e quello delle prestazioni di assistenza ospedaliera per acuti erogate in regime di ricovero diurno abbiamo stimato che un singolo paziente complicato ma non operato in regime d’urgenza abbia determinato un ingente spesa per il sistema sanitario ( gruppo B: circa 3513,2 €) circa 1.9 volte in più se paragonata a un paziente che durante l’attesa non abbia sviluppato complicanze ( gruppo A: circa 1.849,4 €) o 1.36 volte in più di un paziente precocemente operato in regime d’urgenza (gruppo c: circa 2.584,6 €).

  5. High resolution timing and style of coseismic deformation: Paleoseismic studies on the northern and southern San Andreas Fault

    NASA Astrophysics Data System (ADS)

    Streig, Ashley Rebecca

    Critical inputs to evaluate fault behavior models include the frequency of large earthquakes on plate boundary faults, amount of displacement, style of deformation in these events, and how these earthquakes are associated with adjacent sites and broader segments. Paleoseismic data provide these inputs and allow the characterization of hazard posed by individual faults. This dissertation presents results from paleoseismic studies at Hazel Dell and Frazier Mountain that provide new earthquake chronologies and slip estimates for the San Andreas Fault (SAF). These data provide new insights into the recurrence and style of coseismic deformation for surface rupturing earthquakes on the SAF. The Hazel Dell site provides the first definitive paleoseismic evidence of two pre-1906, 19th century earthquakes on the Santa Cruz Mountains section of the SAF. I correlate these paleoseismic findings with the historic record of ground shaking associated with earthquakes in that period and combine the style of deformation in the last 3 events at the site with results from nearby paleoseismic sites to estimate earthquake rupture lengths and magnitudes for these early historic events. These findings increase the frequency of historic surface rupturing earthquakes on the northern SAF three-fold. At the Frazier Mountain site, on the southern SAF, I mapped deformation across a releasing step on the fault for the last five surface rupturing earthquakes to estimate deformation per-event. I compare the geometry and amount of vertical relief generated across the step-over by retrodeforming 3D surfaces interpolated from paleoseismic data step-wise for stratigraphic units deformed by each of those earthquakes. I find that structural relief is similar in four of the last five events, so slip on the fault must be within the same range for these earthquakes to generate approximately equivalent structural relief across the step-over. These results suggest displacement on the fault is comparable at

    Sommario INTRODUZIONE: Scopo dello studio è valutare le caratteristiche ecografiche e cliniche di endometriomi in prossimità di cicatrice di Pfannenstiel in rapporto a ritardo diagnostico segnalato da dimensioni ≥ 30 mm al momento della diagnosi istologica. METODI: Sono stati confrontati i dati clinico-anamnestici, ecografici e Color Doppler di 13 pazienti (età media 31.3 anni) con 13 endometriomi ≥ 30 mm (Ø medio 41.8 mm; range 30–60 mm) e di 17 pazienti (età media 30.7 anni) con 19 endometriomi < 30 mm (Ø medio 18.3 mm; range 7–26). In tutti i casi era disponibile il risultato istologico su campione operatorio. RISULTATI: Nelle pazienti con endometrioma ≥30 mm risultavano più lunghi sia il tempo medio intercorso tra il ricovero e ultimo taglio cesareo (5.5 vs. 3.3 anni; p < 0.01) che la durata media dei sintomi prima del ricovero (43 vs. 17.4 mesi; p < 0.01). Inoltre, indagini diagnostiche diverse dall'ecografia (TC, RM, FNB, celioscopia) o interventi chirurgici incongrui si registravano nel 39% delle pazienti con endometriomi ≥ 30 mm, ma in nessuna di quelle con piccoli noduli (p < 0.05). Dal punto di vista ecografico gli endometriomi ≥ 30 mm mostravano più spesso (p < 0.05) perdita della morfologia ovalare, aree liquide interne, tramiti fistolosi e multipli poli vascolari con aumentata vascolarizzazione intralesionale. CONCLUSIONI: Il ritardo nella diagnosi dell'endometrioma su cicatrice di Pfannenstiel, segnalato da una storia clinica più lunga e complessa, modifica i caratteri ecostrutturali più tipici dell'endometrioma e può rendere ancora più difficile il riconoscimento di questa condizione patologica.

    La recente introduzione di tecniche meno invasive in alternativa al tradizionale stripping safenico ha rivoluzionato il trattamento delle vene varicose (VV), soprattutto nelle Unità Operative a prevalente indirizzo flebologico, ove la scleroterapia con mousse, il laser o la termoablazione con radiofrequenza (RFA) vengono applicate sempre più frequentemente con parallela riduzione del ricorso alle tecniche di chirurgia open. Nella nostra Unità Operativa Complessa di Chirurgia Vascolare, la patologia venosa viene affrontata da sempre, parallelamente a quella arteriosa; in particolare dal 2013, superata la prima fase di apprendimento, anche nella nostra Unità Operativa è stato introdotto l’uso sistematico della RFA per il trattamento dell’incontinenza della vena grande safena (VGS). Abbiamo dunque retrospettivamente esaminato la nostra esperienza nel trattamento delle VV con particolare analisi del modo in cui il nostro approccio terapeutico è cambiato nel corso degli ultimi anni. I dati di tutti i pazienti trattati consecutivamente dal 1 settembre 2013 al 31 Luglio 2015 per VV essenziali e recidive sono stati pertanto retrospettivamente raccolti e analizzati. L’analisi statistica è stata effettuata utilizzando il software JMP 5.1.2 (SAS Institute). Sono state trattate in totale 409 gambe in 378 pazienti. La percentuale di stripping della VGS per VV essenziali è diminuita nel corso degli anni (67% nel 2013 contro il 15.2% nel 2015), a differenza di quello che è successo alla percentuale della RFA della VGS (14.3% vs. 31.5% rispettivamente nel 2013 e nel 2015) e alla percentuale di gambe trattate con la tecnica ASVAL (8.7% vs 31.5%, rispettivamente, nel 2013 e nel 2015). Analogamente, nel 2013 la maggior parte delle procedure è stata eseguita utilizzando l’anestesia spinale (77.5%), mentre nel 2015 le tecniche anestesiologiche più utilizzate sono state l’anestesia locale e l’anestesia locale con sedazione (rispettivamente 35.9% e 29.3%).

    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.

  9. A classification of perceptual corrections of perspective distortions in renaissance painting.

    2010-01-01

    In an attempt to address major debates in perspective studies, this study brings perceptual research to bear on the problem of the status of perspective in the Renaissance. Between one school that sees perspective as mathematically rigorous but imperfectly applied and another that regards perspective as an incoherent discipline, this study argues that errors in the use of perspective are consistent and can be classified into two tendencies: first, the tendency to normalize a foreshortened form towards frontality and, second, the tendency to flatten a three-dimensional object to reveal its hidden sides. These tendencies find confirmation both in the Renaissance doctrine of the judgment of the eye (giudizio dell'occhio) as well as in Gestalt-oriented perceptual research. Numerous examples of their application are given with regard to the representation of human figures, architecture, and the relation of figures to space.

    Adaptive resolution simulations for classical systems are currently made within a reasonably consistent theoretical framework. Recently we have extended this approach to the quantum-classical coupling by mapping the quantum nature of an atom onto a classical polymer ring representation within the path integral approach [Poma & Delle Site, Phys. Rev. Lett., 2010, 104, 250201]. In this way the process of interfacing adaptively a quantum representation to a classical one corresponds to the problem of interfacing two regions with a different number of effective "classical" degrees of freedom; thus the classical formulation of the adaptive algorithm applies straightforwardly to the quantum-classical problem. In this work we show the robustness of such an approach for a liquid of para-hydrogen at low temperature. This system represents a highly challenging conceptual and technical test for the adaptive approach due to the extreme thermodynamical conditions where quantum effects play a central role.

    The scientific heritage held in the National Institute for Astrophysics (INAF), made up of rare and modern books, instruments, and archival documents spanning from the 15th to the early 20th century, marks the milestones in the history of astronomy in Italy. To promote this history of this historical collection, the Libraries and Historical Archives Service and the Museums Service of INAF have developed a project aimed at creating a single web portal: Polvere di stelle. I beni culturali dell'astronomia italiana (Stardust. The cultural heritage of the Italian astronomy). This portal searches for data coming from the libraries, the instruments collections and the historical archives, regarding the heritage of the Italian Observatories. The BID (Books, Instruments, Documents) of the project is the creation of a multimedia web facility, which allows the public to make simultaneous searches on the three different types of materials.

    The irradiation of food is a technology used in the industry to prevent the deterioration of foodstuff in some countries. The European Community legislation states that each Member State must carry out annual checks on the products during commercialisation. The Istituto Zooprofilattico Sperimentale delle regioni Lazio e Toscana (Rome, Italy) has developed and validated the screening method of photostimulated luminescence UNI EN 13751:2009 to identify irradiated shellfish. A total of 30 tests of shellfish samples, consisting of 22 certified as irradiated and 8 not-irradiated samples, were performed. The validation procedure was based on sensitivity and specificity; the compatibility between the screening method and the reference standard EN 13751:2009 was evaluated. Data were processed: 100% sensitivity and 100% specificity were obtained. Results obtained in our laboratory were perfectly compatible with the reference standard. For this reason, the method has been validated and proved to be suitable for its intended use. PMID:27800335

The main goal of this publication is in fact to provide a basis for an in-depth discussion of highly debated topics in the contemporary bioethics of animal experimentation, with particular focus on ethological issues and the question of minimal sample size and its contribution to reducing the number of experimental animals. The ethological issues addressed in this publication cover all behavioural patterns specifically moulded by the phylogenetic and ontogenetical history of a given species, a perspective that is often neglected when discussing the promotion of animal welfare.

    Although Italian mental health (MH) services are community based, user and relative participation in service evaluation lagged behind until lately. We here review three recent studies involving stakeholder participation in service evaluation: two were quantitative studies, one on 204 users in an MH service in Pistoia (Central Italy) and the other on 2259 relatives, conducted with the National Union of Associations for Mental Health. The third (supported by The Centro per il Controllo delle Malattie, the ministerial Center for Disease Control) was a qualitative study in seven MH services, involving users, relatives, and professionals together, which collected interviews from 136 users, 119 relatives, and 79 professionals. In the quantitative studies, positive evaluations outnumbered negative ones. The qualitative study explored negative aspects in greater depth. Common findings were insufficient information, underinvolvement of users-relatives in planning, no choice of clinician, psychiatrist domination, and limited helpfulness of interventions. With stakeholder participation in service evaluation, the present medical framework will need reshaping.

    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

    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.

    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).

    Polyclad species diversity, although generally well known for European North Atlantic waters, is nearly unknown for the Iberian Peninsula. The "Ría de Arousa", located on the Atlantic coast of Galicia (Spain), is a place where many positive biological factors for species biodiversity converge. Therefore, it is an ideal location to study polyclad diversity. This research, which describes new records and new species, contributes to the knowledge of the distribution of Polycladida (Platyhelminthes), particularly of the suborder Acotylea, in the Atlantic waters of the Iberian Peninsula. The new records include the re-descriptions of Cryptocelis compacta Lang, 1884, Stylochus neapolitanus (Delle Chiaje, 1841-1844) and Discocelis tigrina (Blanchard, 1847), while the two newly described species are Hoploplana elisabelloi n. sp. and Armatoplana celta n. sp.

    2014-01-01

    Solid-state nuclear track detectors are commonly used for the detection of indoor radon levels. However, despite numerous advantages, this technique still presents many unsolved problems. An important source of error is represented by the reduction in the detection efficiency due to overlapping tracks, which results in a sensible underestimation of the radon levels. This paper presents a new experimental procedure to address the effect of overlapping tracks by establishing a relationship between the detection efficiency and the number of detected tracks. Experimental data have been collected at the radon chamber of the Istituto Nazionale di Metrologia delle Radiazioni Ionizzanti (INMRI), at the ENEA centre in Casaccia, using CR-39 detectors provided by Radosys Ltd. It has been proved that the method, applied to the experimental settings of this study, gives reliable results up to 7607 kBq h m(-3). Finally, the method has been validated through a Monte Carlo simulation, exploring a wide range of radon exposure.

    The aim of this study was to investigate the effect of ageing and fading on PADC detector response, as a function of the storage time and temperature. Several groups of CR-39 detectors provided by Radosys, Ltd. were exposed at the reference radon chamber of the Istituto Nazionale di Metrologia delle Radiazioni Ionizzanti, at the ENEA centre in Casaccia. The results indicate that low-temperature storage inhibits the effect of both ageing and fading. Finally, the overall reduction in CR-39 sensitivity due to the combined ageing/fading effect was estimated. In particular, the sensitivity of the detectors continuously exposed in air at room temperature over 6 and 3 months was reduced, respectively, by 7.5 and 4 %.

    The Santa Cruz Mountains section (SAS) of the San Andreas fault last ruptured during the 1906 earthquake, an event that ruptured about 470 km, from Point Arena to San Juan Bautista, California. Paleoseismic studies on the SAS at the Grizzly Flat (GF) and Arano Flat - Mill Creek (AF) paleoseismic sites provide evidence of 1906 surface deformation, but have yielded differing records of prehistoric surface-fault ruptures. GF is located 14 km northwest of the AF site and records one 17th Century earthquake dated between 1632-1659 (Schwartz et al., 1996). The record at AF site records a younger penultimate earthquake between AD 1711 - 1770, with a third event between AD 1660-1670 (Fumal, in review). The AF sites suggest nine earthquakes in the past ~1000 years, and an average recurrence interval of 105 years over the past 1,000 years (Fumal et al., 2003). The Hazel Dell site is located approximately 9.5 km north of AF, between the AF and GF sites. This site has yielded good evidence of the most recent earthquake the 1906 surface rupture (E1), and 3 to 4 earlier events, including new evidence for two mid 1800's earthquakes. Evidence for the penultimate event, E2, is expressed as upward fault terminations within a massive sand infilling a topographic low. This sand infilled a depression formed by the pre-penultimate earthquake, E3. We identified milled wood stratigraphically below the pre-penultimate earthquake horizon, which suggests that surface rupturing earthquakes E2 and E3 occurred after deposition of the milled wood stratigraphic unit. Lumber harvesting began in the area around 1832, which suggests that earthquakes E2 and E3 are historical. Based on the presence of milled wood, the stratigraphic record at Hazel Dell appears more complete during the early historical period than at the AF and GF sites. These new event data for the SAS suggest more frequent surface rupturing earthquakes within historical time than previously recognized. We present a preliminary short

    The present study provides Italian normative measures for 266 line drawings belonging to the new set of pictures developed by Lotto, Dell'Acqua, and Job (in press). The pictures have been standardized on the following measures: number of letters, number of syllables, name frequency, within-category typically, familiarity, age of acquisition, name agreement, and naming time. In addition to providing the measures, the present study focuses on indirect and direct comparisons (i.e., correlations) of the present norms with databases provided by comparable studies in Italian (in which normative data were collected with Snodgrass & Vanderwart's set of pictures; Nisi, Longoni, & Snodgrass, 2000), in British English (Barry, Morrison, & Ellis, 1997), in American English (Snodgrass & Vanderwart, 1980; Snodgrass & Yuditsky, 1996), in French (Alario & Ferrand, 1999), and in Spanish (Sanfeliu & Fernandez, 1996).

    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.

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

    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.

  8. 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.

    In the Ross Sea (Antarctica), sedimentation is controlled by the dynamics of the ice shelves, fluctuations of the ice sheets extensions (Eastern and Western) and volcanic activity from several volcanic complex of the Victoria Land. Marine sediments consisting of alternated glacigenic, biogenic and volcanic deposits can be interpreted in terms of changes in paleoclimate and paleoenvironment conditions. In this project we present a multidisciplinary study (comprising tephrostratigraphy, petrology, paleomagnetism, rock magnetism, TIC/TOC geochemistry, Ar/Ar dating, palinology and integrated biostratigraphy of forams and calcareous nannoplankton) of the sediments recovered in selected cores from Ross Sea during 1999 and 2000 cruises and stored in the Italian archive at Museo Nazionale dell'Antartide (Trieste). Results provide new data on local and/or global changes of paleoclimate and paleoenvironmental conditions over the past 50 Ka. Furthermore, the study of the recovered volcanic deposits adds new information about the poorly known, recent volcanic activity in the Victoria Land area.

    Switzerland has recently issued regulations designed to control all trials with drugs in human subjects, namely the 'Regolamento dell'Ufficio Intercantonale per il controllo dei medicamenti in fase di studio clinico' (Intercantonal Regulations Controlling Drugs used in Clinical Trials), which have been operating since 1st January 1995. These new regulations are generally consistent with other international regulations and have introduced the concept of good clinical practice (GCP) into Switzerland. There are other regulations in Switzerland, such as Federal regulations on immunobiological products, special rules governing the administration of radiolabelled drugs to humans, drugs of abuse and medical devices. Any gap in the central regulations must be filled by cantonal regulations, where they exist. This is a comprehensive review of the regulations governing clinical trials in Switzerland, with special attention being devoted to trials with therapeutic compounds and to compatibility between Swiss and international procedures.

    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.

    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.

    With support from my parents, I fulfilled their and my expectations of graduating from college and becoming a scientist. My scientific career has focused on two organisms, Bacillus subtilis and Agrobacterium tumefaciens, and two experimental systems, aromatic amino acid synthesis and DNA transfer in bacteria and plants. Studies on B. subtilis emphasized the genetics and biochemistry of aromatic amino acid synthesis and the characterization of competence in DNA transformation. I carried out both as a postdoc at Stanford with Josh Lederberg. At the University of Washington, I continued these studies and then investigated how Agrobacterium transforms plant cells. In collaboration, Milt Gordon, Mary-Dell Chilton, and I found that this bacterium could transfer a piece of its plasmid into plant cells and thereby modify their properties. This discovery opened up a host of intriguing questions that we have tried to answer over the last 35 years.

    Sommario INTRODUZIONE: All’ecografia con Mezzo di Contrasto (CEUS) dei tumori secondari epatici si evidenzia spesso un alone periferico ipervascolare, che non ha corrispondenza sull’immagine ecografica di base e non è ancora stato caratterizzato istologicamente. Lo scopo dello studio è di caratterizzare tale alone al fine di determinare se sia necessario includerlo nel volume di necrosi pianificato. MATERIALI E METODI: Questo studio prospettico ha incluso 25 pazienti inviati per terapia termo-ablativa di tumori secondari epatici. Prima del trattamento tutti i pazienti sono stati sottoposti a CEUS. Il diametro maggiore della lesione è stato determinato: pre-contrasto, durante la fase arteriosa e durante la fase venosa portale. I diametri delle lesioni pre e post-contrasto sono stati confrontati mediante il test di Turkey–Kramer. Due campioni bioptici sono stati prelevati con ago 21-gauge e analizzati istologicamente: 1) uno dalla zona centrale del tumore e 2) uno dall’alone periferico ipervascolare, identificato alla CEUS solamente nella fase arteriosa. RISULTATI: Il diametro massimo medio delle lesioni è risultato (±deviazione standard): 2,67 ± 1,2 cm pre-contrasto; 3,50 ± 1,4 cm in fase arteriosa; 2,71 ± 1,2 cm in fase venosa. La differenza media tra il diametro massimo pre-contrasto e in fase arteriosa è risultata di 0,84 ± 0,45cm (p<0,0001). All’esame istologico, 24/25 campioni (96%) hanno dimostrato flogosi senza evidenza di tumore microscopico. DISCUSSIONE: L’alone ipervascolare periferico è costituito da infiltrato infiammatorio, non da tessuto tumorale. Esistono evidenze in letteratura che l’infiammazione cronica promuova la neovascolarizzazione e la produzione di fattori di crescita per le cellule neoplastiche. Sembra quindi opportuno includere completamente l’alone ipervascolare periferico evidente alla CEUS nel volume di termo-ablazione.

    Low latitude ice cores offer unique and detailed paleoclimate information from high elevations. Multiple proxies synchronized within the same ice medium offer the possibility to precisely link past climate variations to changes in the surrounding ecosystems and human activities, providing a unique paleo-geographic perspective of the Earth system. However, as most of the accessible low latitude drilling sites have already been exploited and as glaciers are melting worldwide, it is difficult to identify ice fields that contain novel and intact ice core records. We drilled the first ice cores to bedrock in the eastern European Alps during autumn 2011. These cores were extracted from the Alto dell'Ortles glacier (3859 m, South Tyrol, Italy) and their length was up to 75 m. The firn-ice transition was found at ~30 m depth. Below the temperate firn portion, cold ice layers sitting on frozen bedrock still exist and represent remnants from the colder climate before ~1980 AD. Analysis of beta emissions and tritium indicate the well-known 1963 peak (originating from radioactive nuclear fallout) to be at 41 m depth. Together with a measured density profile, this allows us to estimate an average accumulation rate of ~ 850 mm of water equivalent per year during the last 50 years. This confirms this drilling site as one with the lowest snow accumulation rate in the Alps, potentially containing older ice than most of the other Alpine glaciers. Preliminary analyses reveal that the deep and cold ice layers of this glacier preserve clearly distinguishable annual variations in stable isotopes, dust and major ions that can be precisely dated. Alto dell'Ortles is the first low-accumulation alpine drilling site where both winter and summer layers can be clearly identified. Application of a conventional flow model and preliminary annual layer counting suggest that the high altitude records contained in these ice cores may span at least several centuries.

    The Gaia mission will observe between 2.5 and 3x105 Solar System objects. Most of them will be asteroids. As described elsewhere (Cellino et al. 2007, Tanga et al. 2007, Mignard et al. 2008) Gaia will provide a complete dynamical and physical characterisation of these bodies, that has no comparisons with the datasets ever obtained by a single groundor spacebased telescope. In fact, high precision astrometry, flux measurements and spectra will be available in an homogeneous set of data. However, in order to fully exploit the scientific potential of the data, a dedicated processing structure is needed. For this reason, a specific data reduction and analysis pipeline is under development. Some aspects of the implementation require solving interesting challenges in Solar System dynamics, consisting in new and more complex formulations of classic problems. We discuss, in particular, the determination of asteroid masses and the measurement of non-gravitational forces. Also, we show that - in the case of Solar System objects - the high astrometric accuracy of Gaia cannot completely rule out the use of ground-based data for increasing the extent of the final mission products. Well planned and focused preand post-mission observational campaigns could thus greatly help to reach goals situated at the edge (or beyond) the reach of Gaia observations alone.

    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.

    Lo stress ossidativo gioca un ruolo importante nella patogenesi delle malattie neoplastiche. La prolidasi è un costituente della matrice metalloproteinasica, gioca un ruolo maggiore nel metabolismo del collagene, nell’accrescimento cellulare e nel rimodellamento strutturale. Una elevata attività prolidasica è stata dimostrata in molti casi di carcinomi. Lo scopo del presente studio è quello di indagare sull’attività sierica della prolidasi, dello stato ossidativo (TOS) ed antiossidativo (TAS) totale, e di valutare il loro rapporto con lo stadio del tumore, delle metastasi linfonodali e della massa neoplastica in pazienti con carcinoma mammario. Per lo studio sono state arruolate 35 pazienti con carcinoma della mammella e 40 soggetti di controllo. Sono stati rilevati i livelli di TAS, TOS e dell’attività prolidasica, calcolando gli indici di stress ossidativo (OSI). Come risultato i livelli di TOS, di OSI e dell’attività prolidasica sono risultati significativamente più elevati nelle pazienti con carcinoma mammario rispetto al gruppo di controllo (rispettivamente (P < 0.001, P < 0.001, P = 0.002). I livelli di TAS sono risultati significativamente inferiori nelle pazienti con carcinoma mammario rispetto al gruppo di controllo (P = 0,016). Sono stati rilevate correlazioni positive tra attività prolidasica, ed i livelli di TOS e di OSI con lo stadio tumorale, le metastasi linfoniodali e le dimensioni del tumore. Negativa è risultata la correlazione tra i livelli di TAS e le dimensioni del tunore, ma nessuna correlazione tra i livelli di TAS e lo stadio del tumore, come pure con l’infiltrazione linfonodale. Si conclude che l’elevata attività prolidasica del siero e lo stress ossidativo possono associarsi col carcinoma mammario. L’accresciuta attività prolidasica può essere messa in relazione con lo stadio e la prognosi del carcinoma mammario.

    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.

  3. Numerical identification procedure between a micro-Cauchy model and a macro-second gradient model for planar pantographic structures

    NASA Astrophysics Data System (ADS)

    Giorgio, Ivan

    2016-08-01

    In order to design the microstructure of metamaterials showing high toughness in extension (property to be shared with muscles), it has been recently proposed (Dell'Isola et al. in Z Angew Math Phys 66(6):3473-3498, 2015) to consider pantographic structures. It is possible to model such structures at a suitably small length scale (resolving in detail the interconnecting pivots/cylinders) using a standard Cauchy first gradient theory. However, the computational costs for such modelling choice are not allowing for the study of more complex mechanical systems including for instance many pantographic substructures. The microscopic model considered here is a quadratic isotropic Saint-Venant first gradient continuum including geometric nonlinearities and characterized by two Lamé parameters. The introduced macroscopic two-dimensional model for pantographic sheets is characterized by a deformation energy quadratic both in the first and second gradient of placement. However, as underlined in Dell'Isola et al. (Proc R Soc Lond A 472(2185):20150790, 2016), it is needed that the second gradient stiffness depends on the first gradient of placement if large deformations and large displacements configurations must be described. The numerical identification procedure presented in this paper consists in fitting the macro-constitutive parameters using several numerical simulations performed with the micro-model. The parameters obtained by the best fit identification in few deformation problems fit very well also in many others, showing that the reduced proposed model is suitable to get an effective model at relevantly lower computational effort. The presented numerical evidences suggest that a rigorous mathematical homogenization result most likely holds.

    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.

    La prevalenza mondiale del diabete nel 2000 è stata stimata essere del 2.8% con una previsione del 4.4% nel 2030. A causa della neuropatia e dei processi ischemici che ne derivano, i pazienti diabetici sono purtroppo predisposti all’insorgenza di infezioni a carico del piede con un rischio di amputazione molto elevato. A tal proposito, un trattamento rapido ed efficace del processo necrotizzante impedirebbe complicanze maggiori e la stessa amputazione. Il nostro studio consiste in un’analisi retrospettiva condotta su 20 pazienti atta a valutare l’efficacia del sostituto dermico autologo bioingegnerizzato (Hyalograft 3D Autograft) in associazione alla V.A.C (vacuum assisted closure) Therapy per il trattamento delle ulcere diabetiche, rispetto ai metodi sinora impiegati. I pazienti selezionati, a seconda del trattamento eseguito, sono stati suddivisi in due gruppi omogenei di dieci pazienti ciascuno. Il gruppo controllo è stato trattato con il metodo standard, ovvero con debridment chirurgico e innesti cutanei autologhi, mentre il gruppo studio è stato trattato con il metodo in analisi. La raccolta dei dati ha suggerito come l’impiego combinato del sostituto dermico bioingegnerizzato e della pressione negativa determini, rispetto al gruppo controllo, un aumento della percentuale di guarigione, una riduzione del tasso di recidiva di lesioni anche estese e una maggiore ripresa della deambulazione autonoma. In conclusione, la nostra analisi ha evidenziato un metodo sicuro, affidabile e competitivo per il trattamento di ampie lesioni necrotizzanti del piede diabetico. Anche se ulteriori valutazioni sono necessarie, crediamo fortemente che l’associazione del derma bioingegnerizzato e della pressione negativa possa condurre ad una rapida ed efficace guarigione delle ulcere, migliorando la qualità della vita del paziente diabetico.

    Il mesotelioma peritoneale maligno è una patologia rara la cui diagnosi è resa particolarmente difficile dalla molteplicità delle possibili presentazioni cliniche e morfologiche. A differenza della patologia pleurica, questa sembra avere una minore correlazione con l’esposizione all’asbesto. La prognosi è sfavorevole con una sopravvivenza media di 5.4 mesi. Riportiamo un caso di mesotelioma peritoneale in un paziente di 73 anni con esposizione professionale all’asbesto. La diagnosi è verosimilmente avvenuta dopo diversi inquadramenti clinici, che hanno compreso addominalgie attribuite ad IBD, poi non accertate istologicamente, e ad un’appendicite acuta. Per ultimo il paziente è giunto alla nostra osservazione con un quadro subocclusivo che l’indagine TC attribuiva ad una verosimile carcinosi peritoneale a primitivo sconosciuto. La laparoscopia esplorativa, poi convertita in approccio laparotomico, ha mostrato un quadro di peritonite incapsulante che coinvolgeva estesamente l’intestino tenue. È stata eseguita una resezione intestinale del tenue coinvolto ed una asportazione di un’area nodulare peri-splenica. L’esame istologico con l’integrazione di indagini immunoistochimiche ha permesso la diagnosi di mesotelioma peritoneale cistico maligno con istotipo bifasico che risulta essere il primo descritto in letteratura. Le aree cistiche avevano inizialmente fatto propendere per una diagnosi di mesotelioma multicistico benigno o di mesotelioma cistico con secondaria proliferazione miofibroblastica pseudosarcomatosa. Negli ultimi anni la prognosi di questa patologia ha trovato nell’utilizzo della chirurgia citoriduttiva e della chemioterapia intraperitoneale un miglioramento prognostico, queste nuove tecniche sono disponibili in centri di riferimento e trovano ad oggi indicazione solo in casi selezionati e in istotipi poco aggressivi.

    Sommario INTRODUZIONE: La tendinopatia calcifica di spalla è una condizione relativamente frequente caratterizzata, quando sintomatica, da dolore cronico e da fasi di dolore acuto molto intenso. MATERIALI E METODI: Da ottobre 2006 a marzo 2008 abbiamo trattato 126 spalle di 125 pazienti consecutivi. Tutti hanno eseguito Rx ed ecografia prima del trattamento ed il test di Constant prima del trattamento e a 6 mesi di distanza. 55 pazienti su 123 (42%) sono stati trattati due o più volte con infiltrazione intrabursale di corticosteroide. Tre pazienti hanno rifiutato altri trattamenti dopo il primo. Sono stati quindi raccolti i dati complessivamente di 123 spalle. È stata eseguita RM di controllo a sei mesi. RISULTATI: Incremento del Constant Score dopo la procedura in tutti i pazienti trattati una sola volta ed in quasi tutti i pazienti trattati due volte; i pazienti sono stati divisi in due classi, rispettivamente trattati una o due (o più) volte. In ciascuna delle due classi c’è stato un significativo incremento (p < 0,0001)delle medie dei Cs pre e post trattamento; nella classe dei pazienti trattati due volte significatività statistica (p < 0,0001) tra le medie dei Cs rispettivamente prima del trattamento iniziale e dopo il primo trattamento, e tra la media Cs di quest’ultimo e quella dopo 6 mesi dal primo trattamento. Il Cs dopo il trattamento è significativamente diverso nei pazienti con impingement (p < 0,001). CONCLUSION: Incremento del Cs, in più del 95% dei pazienti. Non lesioni tendinee ai controlli ecografici/RM. L’impingement è risultato un fattore di rischio per il risultato finale.

    Scopo. Documentare la frequenza e la tipologia degli sprechi nella pratica clinica infermieristica nonché le differenze tra l’area medica e chirurgica. Metodo. È stato condotto uno studio cross-sectional in un’Azienda Sanitaria del nord Italia. La raccolta dati, condotta su 100 infermieri nel settembre 2015, è stata effettuata con un questionario semi-strutturato costituito da 56 item suddivisi in 8 dimensioni di spreco (Sovrapproduzione/Sottoutilizzo, Attese, Scorte, Processo, Disservizi ed errori, Trasporto materiali e flussi informativi, Movimenti, Dispersione delle conoscenze). Risultati. Nella settimana lavorativa sono stati segnalati 2028 sprechi, con una media di 20.2 ±9.2 infermiere. Settecentocinquantanove (37.4%) di essi si sono verificati in area medica, mentre 1269 (63.6%) in area chirurgica. Nella dimensione “processo” si è verificato il maggior numero di sprechi (398; 19.6%). Nelle diverse dimensioni le principali tipologie di spreco sono state: l’uso improprio di energia (30.0%), l’attesa del medico (17.1%), la carenza di materiali (33.1%), l’eccesso di risorse umane distribuite in modo non ottimale (31.8%), la disponibilità di risorse umane inferiore alle esigenze organizzative (22.4%), le prescrizioni terapeutiche incomprensibili e/o incomplete da parte del medico (22.6%), la ricerca di presidi in magazzini lontani o esterni al reparto (23.9%), il trasferimento di utenti da un reparto ad un altro (30.0%) e la ridotta applicazione delle evidenze scientifiche nella pratica clinica (51.7%). Non sono emerse differenze significative tra le due aree cliniche indagate (p-value = 0.480). Conclusioni. Lo studio rappresenta un contribuito al dibattito nazionale sul fenomeno degli sprechi in ambito sanitario e fornisce utili spunti di riflessione sulle possibili strategie di contenimento.

  9. Analytical applications and effective properties of a second gradient isotropic elastic material model

    2015-06-01

    Recently, the works by Toupin, Mindlin, Sokolowski and Germain have been developed following two research streams. In the first one, higher-order gradient continuum models were developed based on the Cauchy tetrahedron argument (see, e.g., dell'Isola and Seppecher in Comptes Rendus de l Academie de Sciences 17 Serie IIb: Mecanique, Physique, Chimie, Astronomie 321:303-308, 1995, Meccanica 32:33-52 1997, Zeitschrift fr Angewandte Mathematik und Physik 63(6):1119-1141, 2012). In the second one, the structure of higher-order gradient models is developed with a view to the applications. In particular in the model of linear isotropic solids proposed by Dell'Isola, Sciarra and Vidoli (DSV), the main constitutive equation is obtained for the case of second gradient models. This model introduces in addition to the two well-known Lame's elastic constants five constitutive constants. The practical applications of this model remain in its infancy since the issue of determining the new moduli it introduces is not yet completely addressed. Also, analytical solutions of simple boundary value problems that can be helpful to grasp some of the physical foundations of this model are missing. This paper aims to address these two issues by providing the analytical solutions for two model problems, a spherical shell subjected to axisymmetric loading conditions and the circular bending of a beam in plane strain, both the beam and the shell obeying the DSV second gradient isotropic elastic model. The solution of the circular bending of a beam has served to grasp some of the physical soundness of the model. A framework based on homogenization under inhomogeneous boundary conditions is also suggested to determine the unknown constitutive constants, which are provided in the particular case of elastic porous heterogeneous materials.

    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.

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

    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.

    Paleoseismic investigations at the Hazel Dell site on the Santa Cruz Mountains section (SAS) of the San Andreas fault has yielded evidence of four earthquakes. We present evidence of the 1906 surface rupture (E1), and 3 earlier events, including new evidence for two 1800's earthquakes. Evidence for the penultimate event, E2, is expressed as upward fault terminations within a massive sand infilling a topographic low. This sand infilled a depression formed by the pre-penultimate earthquake, E3. We identified axe-cut wood stratigraphically below the pre-penultimate earthquake horizon, which suggests that surface rupturing earthquakes E2 and E3 occurred after deposition of the cut wood stratigraphic unit. Lumber harvesting began in the area around 1832, and new radiocarbon dates sampled from redwood growth rings demonstrate that earthquakes E2 and E3 are historical. E4 occurred between A.D. 1651 and 1497. These new event data for the SAS suggest more frequent surface rupturing earthquakes within historical time than previously recognized. The data require at least two modes of behavior in strain release on the SAS through time. One mode of strain release, is through large multi-segment earthquakes; the 1906 event was a large multi-segment earthquake that dominates the moment budget of the fault. During the period prior to 1906, analysis of the historic record suggests that the SAS was characterized by a second mode of moderate seismicity, with six M≥ 6 earthquakes between 1838 and 1890 (Bakun, 1999), all located along the southern half of the segment near the Hazel Dell study area. The two 1800's earthquakes identified in this study support this second mode of moderate seismicity on the SAS.

    La formazione in Chirurgia è un tema di grande interesse in un’epoca di crisi, ma anche di grandi cambiamenti mossi dalla spinta della Comunità Europea di uniformare i Percorsi Formativi di tutti i suoi Stati Membri. I punti principali delle riforme attuate per uniformarci al contesto Comunitario, vertevano sulla riduzione dei tempi e sulla implementazione della multidisciplinarietà della formazione specialistica, con il rischio di adombrare quelli che sono i punti di forza del nostro Sistema Sanitario, tra cui l’alto livello assistenziale dei nostri ospedali territoriali. La Scuola di Specializzazione di Chirurgia Generale dell’UNIVPM da alcuni anni punta su un progetto che vede la Clinica Universitaria al Centro di una Formazione Specialistica che si sviluppa sempre più sul territorio, avvicinando il mondo Ospedaliero a quello Universitario. Questo nuovo modello organizzativo prevede una prima fase all’interno della Clinica Universitaria ed una seconda nella Rete Formativa, nella quale rientrano Centri a differente impatto specialistico, all’interno di Strutture Ospedaliere Italiane ed Estere, e la possibilità di poter collaborare con l’Organizzazione di Emergency. Per testare questa nuova organizzazione del Corso Specialistico, abbiamo preso in analisi l’attività chirurgica svolta dagli specializzandi del nostro Ateneo, che hanno terminato il loro percorso formativo in Chirurgia Generale a Marzo 2014, essendo loro i primi ad aver beneficiato di questo modello. L’attività operatoria è stata, per ciascuno, mediamente di 400 interventi da primo operatore (237-476) distribuiti in chirurgia maggiore 44 (13-80), media 172 (129-268) e minore 209 (70-378), rapportando i loro risultati con gli standard complessivi di addestramento professionalizzante previsti dallo Statuto Nazionale si osserva il buon rendimento di questo sistema, che vede i suoi punti di forza nell’EQUITA dell’offerta, in quanto standardizzabile; nel concetto di RETE

    Scopo. La valutazione della formazione accademica è diventata fondamentale nell'Unione Europea da quando il Processo di Bologna ha incoraggiato tutte le università europee a raggiungere elevati standard di qualità nella formazione. Anche se diversi studi sono stati condotti sulla qualità della formazione negli studenti di infermieristica, pochi hanno esplorato questa tematica dalla prospettiva degli studenti. Lo scopo di questo studio è stato di descrivere l'esperienza della qualità formativa negli studenti del corso di laurea in infermieristica. Metodo. E’ stato utilizzato il metodo fenomenologico per studiare 55 studenti (età media 24 anni; 73% donne) che frequentavano il corso di laurea in infermieristica in tre università del centro Italia. Risultati. Dall'analisi fenomenologica sono emersi i seguenti cinque temi: 1) Qualità dei docenti: capacità di insegnamento, preparazione, sensibilità per gli studenti, autodisciplina; 2) Integrazione teoria-pratica e comunicazione tra l'insegnamento e l'area clinica; 3) gestione generale e organizzazione del corso; 4) la qualità delle infrastrutture: biblioteche, aule, tecnologie dell'informazione, servizi, amministrazione, comunicazione; e 5) tutorato clinico: umanità, relazioni e capacità del tutor clinico di guidare e supportare lo studente. Conclusione. I risultati di questo studio forniscono una comprensione nuova e più approfondita sul significato della qualità della formazione negli studenti di infermieristica. Gli studenti ritenevano che la qualità della formazione consistesse nella sensibilità dei docenti verso i loro problemi e nell’umanità, capacità interpersonali, guida e supporto dei tutor cli.

    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.

    Glacier ice cores from the mid latitude are capable of retaining essential information on past climate, environmental and human activities on a seasonal/annual time resolution. However, for a correct interpretation of the ice record a good chronological control is essential. Absolute time markers such as 3H peaks and Sahara dust horizons, together with radiometric methods such as 210Pb, radiocarbon from carbonaceous aerosol particles and AMS-dating are commonly used to obtain the age depth model of ice cores. In this frame we present the first pollen-based chronology from the Eastern Alps. Results of pollen analyses performed on a 10 m firn core taken on the top of Alto dell'Ortles Glacier (3905 m a.s.l.) will be discussed. Palynological data are compared and complemented with stable isotopes, major ions and trace elements analyses. Based on the single species flowering periods, our results show that the pollen spectrum presents seasonal and inter-annual variability that enables to distinguish snow accumulated in the three different flowering seasons and winter snow. According to these four components a seasonal and annual chronology was established, proving that the 10 m firn core encompasses four years of snow accumulation and presents a clear seasonal palynological signal. These first results reveal the potential of pollen content of glacier snow and ice as a chronological tool that can contribute to the construction of a robust chronological model with a seasonal to annual resolution. This study is the first step and the base for future research on deeper ice cores on the Alto dell'Ortles Glacier (Ortles project: www.ortles.org).

    RIASSUNTO. Scopo. Nella riabilitazione psichiatrica il piano di trattamento individuale può essere formulato a partire da strumenti che offrano una valutazione multidimensionale del paziente. Il lavoro si propone di analizzare il rapporto tra gravosità (distress degli operatori) e stile di recupero (integration e sealing over) dalla patologia psicotica. Ipotizzando che esso influenzi il carico gestionale, lo studio si pone l'ulteriore obiettivo di acquisire maggiori elementi che indirizzino la formulazione di piani terapeutico-riabilitativi più efficaci. Metodi. Lo studio è stato condotto presso un centro diurno psichiatrico, struttura semi-residenziale dei servizi psichiatrici del Sistema Sanitario Nazionale in Italia. 45 pazienti reclutati sono stati valutati mediante la Neuropsychiatric Inventory (NPI - versione italiana) e la Integration/Sealing Over Scale (ISOS - versione italiana), nell'arco di tre mesi (marzo-giugno 2014). Risultati. Nel campione esaminato è emerso che la disinibizione, l'irritabilità e l'apatia sono i sintomi che provocano maggiore distress negli operatori, in senso assoluto. Inoltre, i risultati indicano che depressione e ansia recano un grado maggiore di distress nei pazienti sealer. Discussione e conclusione. Gli aspetti della disinibizione, dell'irritabilità e dell'apatia sono risultati più gravosi per gli operatori in quanto richiedono maggiore coinvolgimento nella relazione terapeutica. Sintomi ansiosi e depressivi risultano più gravosi nel gruppo dei sealer, segnalando minore tenuta della negazione della psicosi. I dati osservati sembrano provare che conoscere, differenziare e approfondire i diversi aspetti dello stile di recupero di ciascun paziente consente di stimare l'impegno gestionale fin dalla presa in carico e di ridurre il distress e il rischio di burnout degli operatori.

    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.

    Sommario SCOPO DEL LAVORO: L'artrite settica (SA), che spesso coinvolge mano e polso, è comune nei pazienti con artrite reumatoide (AR) a causa dell'eziologia immunomediata della AR e dell'uso di farmaci immunosoppressivi. Le caratteristiche cliniche e di laboratorio possono non essere utili per distinguere tra recidiva di AR e sovrapposizione di SA. Il ruolo della risonanza magnetica (RM) è stata descritto in diversi studi. Il nostro obiettivo è quello di valutare il ruolo della ecografia (US). Materiali e Metodi. Negli ultimi 4 anni sono stati eseguiti 31 esami di risonanza magnetica della mano e del polso nel sospetto di SA come complicanza di AR. È stata utilizzata una risonanza magnetica da 1.5 T (Siemens Symphony, Erlangen, Germania) con protocollo standardizzato, che comprendeva la somministrazione di mezzo di contrasto; è stata eseguita anche un'ecografia con power Doppler utilizzando un ecografo Philips IU22. RISULTATI: Sono stati analizzati undici punti (secondo lo studio di Graif) per ogni esame di RM e di US. Alla RM il versamento articolare (37,5% di recidiva AR vs 100% sovrapposizioni di SA) e l'edema dei tessuti molli (25% vs 100%) erano indicativi di SA. Anche ecograficamente il versamento articolare (31.3% di AR recidiva 73,3% vs sovrapposizione di SA) e l'edema dei tessuti molli (12,5% vs 60%) erano indicativi di SA. CONCLUSIONE: I nostri risultati confermano che il versamento articolare e l'edema dei tessuti molli sono suggestivi per sovrapposizione di SA e che la RM è più sensibile nella loro valutazione. Anche se l'US è meno sensibile della RM, essa è importante nel guidare procedure invasive e nella valutazione dei pazienti che non possono essere sottoposti a RM.

  1. HUBBLE FINDS THOUSANDS OF GASEOUS FRAGMENTS SURROUNDING DYING STAR

    2002-01-01

    Resembling a bizarre setting from a science fiction movie, dramatic images sent back by NASA's Hubble Space Telescope have surprised astronomers by uncovering thousands of gigantic tadpole-shaped objects surrounding a dying star. Dubbed 'cometary knots' because their glowing heads and gossamer tails superficially resemble comets, they are probably the result of a dying star's final outbursts. Though ground-based telescopic observations have hinted at such objects, they have not previously been seen in such abundance, say researchers. The knots were detected by Hubble astronomer C. Robert O'Dell and graduate student Kerry P. Handron of Rice University in Houston, Texas, while exploring the Helix nebula, a ring of glowing gases blown off the surface of a sunlike star late in its life. O'Dell expects the gaseous knots, which are each several billion miles across, will eventually dissipate and vanish into the cold emptiness of interstellar space. However, he speculates that if the objects contract to form permanent solid bodies, they may contribute to a fraction (less than ten percent) of the missing mass of our galaxy, simply because of their sheer abundance around a typical dying star. (This so-called dark matter is a known source of gravity that affects the motions of stars in the galaxy). The mysterious 'space pods' came into view as O'Dell used Hubble's Wide Field Planetary Camera 2 to survey the Helix nebula, located 450 light-years away in the constellation Aquarius and the closest planetary nebula to Earth -- so close that its angular size is almost half that of the full Moon. The most visible cometary knots all lie along the inner edge of the ring, at a distance of trillions of miles from the central star. Their comet-like tails, each stretching a hundred billion miles, form a radial pattern around the star like the spokes on a wagon wheel. Though previous ground-based observations show a spoke pattern in the Helix, and some structure, O'Dell emphasizes that

Riassunto Introduzione Le mappe tematiche consentono una più rapida ed immediata lettura delle differenze geografiche nella distribuzione di dati riferiti ad un territorio specifico. Lo scopo dello studio è mostrare, per la prima volta, l’applicazione di alcuni strumenti statistici e cartografici, nell’analisi dell’uso dei farmaci nella popolazione pediatrica di una regione italiana e valutare le differenze intra-regionali. Metodi Per valutare il tipo di distribuzione geografica delle prescrizioni, sono stati calcolati i tassi di prevalenza standardizzati (punteggi-z) a livello di ASL, Distretti Sanitari e Comuni. Per valutare la correlazione con le ospedalizzazioni è stato usato il coefficiente di correlazione di Pearson; per valutare l’esistenza di autocorrelazione spaziale è stato usato l’indice I di Moran. Tramite l’uso della statistica G di Getis-Ord sono stati identificati cluster di aree ad alto e basso livello di prevalenza. Infine con un modello di regressione logistica è stata stimata la probabilità di ricevere almeno una prescrizione nel corso dell’anno per tutti i pazienti inclusi nello studio. Risultati Con l’uso delle mappe è possibile vedere che le prescrizioni non sono correlate con lo stato di salute della popolazione, ma sono correlate con l’attitudine prescrittiva del pediatra. Questo è confermato anche dal modello di regressione logistica costruito per stimare la probabilità di ricevere almeno una prescrizione considerando come variabili indipendenti l’età, il sesso, la prevalenza di ricoveri nel distretto di residenza, l’attitudine prescrittiva del pediatra, la classe di età del pediatra e la durata della convenzione del pediatra con l’Azienda Sanitaria Locale (ASL).

    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.

    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). In questo momento inoltre altri due spettrometri sono in avanzata fase di studio: JIRAM (Jovian InfraRed Auroral Mapper) su Juno (missione New Discovery Nasa) e VIHI (Visible and Infrared Hyperspectral Imager) integrato nel payload italiano di remote sensing SIMBIO-SYS di BepiColombo (missione cornerstone ESA).

    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.

    If Martian life evolved during the Noachian period, it likely would have retreated to liquid water refuges where redox chemistry provided metabolically viable substrates. Present-day Mars appears to have such a refuge with data suggesting that liquid water may persist in the subsurface, however limited data is available with regards to subsurface Martian geochemistry and hydrogeology. On Earth, we find microbial communities thriving in subsurface environments utilizing a multitude of lithoautotrophic metabolisms. The Frasassi cave system in Italy hosts many such lithotrophic microbial communities, which are isolated from surface carbon, sunlight, and oxygen similar to possible Martian microbial populations. By studying the community structure, geochemistry and thermodynamics of the system, as well as the metabolic capabilities using metagenomics, we hope to discover microbes are capable of thriving in so-called 'energy-limited' environments and inform the search for life in the solar system. Two subsurface cave lakes in the Frasassi cave system, Lago Infinito and Lago dell'Orsa, have anoxic waters that host rope-like biofilm communities dominated by Deltaproteobacteria, Chloroflexi, and Planctomycetes clades. Thermodynamic calculations based on in situ geochemistry of waters surrounding the biofilms suggest very few metabolisms are energetically-feasible including: 1) anaerobic oxidation of methane (AOM) coupled with sulfate reduction 2) anaerobic ammonia oxidation (anammox) coupled with sulfate reduction 3) methanogenesis (Lago dell'Orsa only) 4) chemotrophic sulfate reduction AOM and anammox were only recently discovered and appear to have low energy yields associated with slow growth rates. AOM coupled with sulfate reduction has been shown to occur in a syntrophy between sulfate-reducing bacteria (SRB) and methanotrophic Archaea. However, these rope-like biofilms have a small (<10%) Archaeal population, which are not closely related to the syntrophic

    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

    The Gromolo Torrent is a metal-polluted Apennine streamflow located near Sestri Levante (Liguria, Italy). It springs from the Monte Rocca Grande (850 m a.s.l.), and flows for 11.5 km through the Gromolo Valley before flowing into the Ligurian Sea. Inside the Gromolo basin is located the abandoned Fe-Cu mine of Libiola, which was the most important sulfide deposit of the Ligurian Apennines. In this mining site, extensive Acid Mine Drainage (AMD) processes are active, both inside the mine tunnels and in the sulfide rich waste-rock dumps; the solutions generated are characterised by low pH values and high amounts of dissolved SO42-, Fe, and other chemical elements such as Cu, Zn, Pb, Al, Co, and Ni. Moreover, exstensively precipitation of Fe and Cu-rich secondary minerals occurs both as soft crusts inside the mine adits and as loose suspensions associated with overland flow of mine drainage. AMD waters flowed into the uncontaminated Gromolo Torrent where abundant precipitation of amorphous Fe(III)-oxy-hydroxides occurred. The marine study area is characterised by the presence of the headland of Sestri Levante with two bays, the western one named "Baia delle Favole". The dynamics of the area is dominated by a permanent north-westward off-shore current flowing approximately along isobath, and an eastward counter-current along the north coast with a resulting drift of the coastal materials from the West to Est towards "Baia delle Favole". The bottom sediment are principally characterised by coarse materials, mostly consisting of fine sand, with a percentage of the fine sediment increasing inside the bay, where the dynamics is low. The aims of this work are to 1) evaluate the metal mobility of colloidal river precipitates for about 7 km up to its mouth in the Ligurian Sea; 2) verify the contamination state of the marine bottom sediments off the mouth of the Gromolo Torrent ("Baia delle Favole" of Sestri Levante), and 3) identify the main sources and diffusion ways of

    This special issue of Metrologia brings together contributions to the International Workshop on the Avogadro Constant and the Representation of the Silicon Mole, held in Turin, Italy, from 9 to 10 March 1994. It was organized by the Istituto di Metrologia "G Colonnetti" (IMGC) del Consiglio Nazionale delle Ricerche (CNR) and the Istituto di Fisica Generale "A Avogadro" (IFG) dell'Università di Tonno. It was sponsored by the CNR, the University of Turin, the Regione Piemonte, and the Commission of the European Communities DG XII. The workshop was a follow-up to previous international meetings held in Turin to commemorate Amedeo Avogadro, one in 1911 (the centenary of the publication of his hypothesis) and another in 1957 (the centenary of his death). On this occasion the workshop was motivated by the requirements of researchers engaged in the international project on the determination of the Avogadro constant by the x-ray crystal density method. Sixty-four participants representing eight countries attended the workshop. Doctoral students in metrology from Turin University and researchers working in adjacent fields were also present. The lectures were chosen so as to review the different aspects of this project, to illustrate progress in research, and to indicate future developments to scientists working in different fields of physics, metrology and technology. Complementary approaches to the NA determination based on electrical measurements were also reported and analysed. During the workshop, a number of specialist meetings allowed experts to discuss specific topics, to exchange information on results and techniques, and to improve the coordination of their activities. In their opening addresses, Prof. C Castagnoli (Director of the IFG) and Prof. L Crovini (Director of the IMGC) welcomed the participants and introduced the work in progress with a view to making a more precise determination of the Avogadro constant. They mentioned the expected influence of this

    Le resezioni coliche laparoscopiche sia per patologie benigne che maligne sono state investigate da importanti RCT che ne hanno dimostrato la sovrapponibilità alla tecnica open convenzionale. La laparoscopia con un numero ridotto di trocar ha da quel momento trovato ampio sviluppo nell’ottica di massimizzare i benefici della mini-invasività. Proponiamo un’analisi dei nostri risultati nell’utilizzo della tecnica three-port nella emicolectomia sinistra attraverso un confronto con la classica resezione laparoscopica con quattro/ cinque accessi. Come è noto i laparoceli si sviluppano maggiormente su incisioni mediane mentre non vi è differenza tra lo sviluppo di questi dopo tecnica open o laparoscopica. Nell’ottica della chirurgia a numero ridotto di accessi, la tecnica single-port sembra dare vantaggi di minor traumatismo ma ciò a costo di aumentate difficoltà di esecuzione, aumento dei tempi operatori e dell’utilizzo di strumenti per lo più dedicati, con incisioni ombelicali che possono superare i 5 cm. Le resezioni coliche three port consentono di ridurre il numero di accessi e dunque delle complicanze a questi correlate con l’utilizzo di strumentazione standard e la possibilità di esecuzione su larga scala da parte di ogni chirurgo. L’analisi che abbiamo eseguito ha dimostrato nella nostra serie una riduzione dei tempi operatori nella tecnica three port e ciò può essere dovuto all’inserimento dei trocar addizionali ed al loro controllo ma soprattutto alla possibilità/ necessità del chirurgo esperto di essere meno influenzato da fattori quali una equipe non dedicata. Non sono stati evidenziati vantaggi nella riduzione della degenza operatoria. Il tasso di conversione è stato maggiore nella tecnica a ridotto numero di accessi, questo è possibile sia un bias legato alle conversioni precoci prima del posizionamento di restanti trocar in casi particolarmente complessi. In conclusione, la tecnica three port appare comparabile alla

    Negli ultimi anni, alcuni chirurghi hanno cercato di rendere sempre meno invasiva la procedura della colecistectomia videolaparoscopica, riducendo il calibro degli strumenti. Nel nostro studio si vogliono dimostrare i vantaggi nell’utilizzo di strumenti miniaturizzati (con diametro di 3mm), comparandoli con la colecistectomia laparoscopica realizzata con strumenti da 5mm. I parametri analizzati nello studio sono: la durata dell’intervento, la durata della degenza, il dolore postoperatorio, le complicanze ed il risultato estetico. Lo studio si basa su una casistica personale di 114 pazienti trattati in un periodo di 12 mesi. Tutti i pazienti sono stati trattati per calcolosi sintomatica della colecisti o per poliposi della colecisti. In 102 pazienti si è trattato di colecistectomia minilaparoscopica e in 12 colecistectomia laparoscopica con strumenti da 5mm o perchè presentavano un eccessivo spessore delle pareti della colecisti che rendeva difficoltosa la presa sull’organo con strumenti di 3mm, o perchè presentavano calcoli lungo la via biliare principale e si rendeva quindi necessario eseguire una colangiografia intraoperatoria. L’esecuzione della tecnica minilaparoscopica richiede particolari accorgimenti per superare piccole difficoltà tecniche in rapporto alla maggiore flessibilità degli stumenti di ridotto calibro e all’impossibilità di applicare clips metalliche con i trocars da 3mm. E’ necessario legare con filo di sutura il dotto cistico mediante nodi intracorporei e coagulare l’arteria cistica con corrente monopolare. La durata dell’intervento risulta in media di 47 minuti per la colecistectomia con strumenti da 5mm e di 50 minuti per la colecistectomia minilaparoscopica. La degenza media è stata di 49 ore per la colecistectomia con strumenti da 5mm e di 18 ore per la colecistectomia minilaparoscopica; 73 pazienti sono stati dimessi lo stesso giorno dell’intervento. Il dolore post operatorio è risultato inferiore nei pazienti

  15. Is vent location an important factor in the assessment of pyroclastic flow hazard from sub-Plinian events at Vesuvius?

    Reconstructions of vent location of past sub-Plinian (and Plinian) eruptions of Vesuvius show a significant spatial variability of the vent inside the caldera area. Moreover, it is likely that the exact location of the vent of a future explosive event of that type at Vesuvius will be unknown until the onset of the event itself. Nevertheless, to our knowledge, no studies exist that analyse the influence of vent location on the simulated eruptive scenarios. This omission could be particularly critical for the assessment of pyroclastic flow (or pyroclastic density current, PDC) hazard due to the specific morphology of the Somma-Vesuvius complex. In this work, we present new numerical simulations of column collapse and pyroclastic density current scenarios at Vesuvius by using the transient 3D multiphase flow code PDAC (Esposti Ongaro et al., Parallel Computing, 33, 2007). Simulations have been carried out by assuming three different locations of the vent within the caldera area: the first is in Valle del Gigante, between Mt. Somma ridge and the present Gran Cono, the second is in Piano delle Ginestre, to the west of the Gran Cono, while the third one is in Valle dell'Inferno, in the south-eastern direction with respect to the Gran Cono. Source conditions for all cases refer to a sub-Plinian event and to both partial and nearly-total collapse of the eruptive column. Simulation results clearly show the first-order effect of vent location on the propagation directions of PDCs and the areal distribution of pyroclasts, owing to the complex interaction of the flow with the proximal volcano morphology. Comparisons with simulations assuming a central vent located in the position of Gran Cono clearly show the different roles of Mt. Somma, Gran Cono, along with mean slope and channelling effects as a function of the assumed vent location. Estimates of the areas invaded by the flows are presented, although the definition of their runout is particularly difficult due to the

    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.

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

    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

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 result, based on the rule of the Environmental Impact Assessment, puts into evidence the

    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

    The characterization of the marine environment plays an important role in the understanding of the dynamics affecting the transport, fate and persistence (TFP) of Persistent Organic Pollutants (POPs). This work is part of a project funded by the Ministero dell'Istruzione, dell'Università e della Ricerca. The aim of the project is the assessment of the TFP of POPs in the Mediterranean sea. The analysis will be carried out at regionalmesoscale (central Mediterranean), and at local spatial scale considering different Italian test sites (the Delta of the Po River, the Venice Lagoon and the estuary of the Rio Nocella). The first step of this work involves the implementation of GIS geodatabases for the definition of the input dataset. The geodatabases were populated with MERIS and MODIS level 2 and level 3 products of Chlorophyll-a (CHL-a), Chromophoric Dissolved Organic Matter (CDOM), Aerosol Optical Thickness (AOT), Diffuse Attenuation Coefficient (DAC), Particulate Inorganic Carbon (PIC), Particulate Organic Carbon (POC) and Sea Surface Temperature (SST). The spatial scale (central Mediterranean sea) and the reference system (Plate Carrée projection) have been imposed as a constraint for the geodatabases. Four geodatabases have been implemented, two for MODIS and two for MERIS products with a monthly, seasonal and climatological temporal scale (2002 -2013). Here, we present a first application of a methodology aimed to identify vulnerable areas to POPs accumulation and persistence. The methodology allowed to assess the spatial distribution of the CHL-a in the central Mediterranean sea. The chlorophyll concentration is related to the amount of nutrients in the water and therefore provides an indicator of the potential presence of POPs. A pilot area of 300 x 200 km located in the North Adriatic sea has been initially considered. The seasonal and climatological MODIS and MERIS CHL-a variability were retrieved and compared with in-situ forcing parameters, i.e. Po River

RI., Salerno Groundwater and surface water resources management represents a present key issue, both in the hydrogeological and the hydrological fields. An integrated approach, accounting for hydrogeological, hydrological, geochemical and biological features can be a valuable tool, being fundamental in karstic landscape because of the great system variability and because of the frequently complex anthropic interaction. In this study we focus on a particular case study, the Bussento river basin, located in the Campania region, Southern Italy, which is well known to hydrogeology and geomorphology scientists for its karstic features, as summit highland with dolines and poljes, lowland with blind valleys, disappearing streams into sinkholes and cave systems. The catchment groundwater circulation is very complex and frequently groundwater inflows from the outside of the hydrological watershed and groundwater outflows toward surrounding drainage systems occur. We aim at propose a validation of a conceptual hydro-geological model (Guida D. et al., 1980; Iaccarino G., et al., 1986; e Guida D. et al.,1988, Guida D. et al., 2005) and to this purpose a measurements campaign, of about one year, has been undertaken along the Bussento for the acquisition of data about the Rn222 concentration in the waters, using a Rad7 water probe and a Rad7H2O (Durridge Inc., South Australia). Besides radon concentration, more chemical and physical variables have been measured, such as pH, water temperature, dissolved oxygen, atmospheric pressure, water conductivity, water resistivity. The preliminary results enable us to consider this as an useful methodology for the localization of the contributions of the groundwaters, diffused along the riverbed, and for their

    Negli ultimi anni, gli ascessi del muscolo ileopsoas sono stati riportati in letteratura con crescente frequenza, probabilmente a causa del largo impiego della TC nella diagnostica differenziale delle algie lombari. Qui presentiamo il caso di una paziente che ha sviluppato un ascesso dell’ileopsoas post-traumatico. Una donna di 43 anni riferiva febbre da 4 settimane, anoressia, dolore al fianco destro e alla regione lombare e difficoltà alla deambulazione. Tale sintomatologia, insorta per la prima volta 20 anni prima in seguito ad una caduta da cavallo, si ripresentava ciclicamente. Per il controllo della febbre e del dolore, la paziente assumeva una terapia antibiotica empirica. Al momento del ricovero gli esami ematochimici mostravano una moderata leucocitosi. La TC dell’addome evidenziava un grosso ascesso multiloculato dello psoas destro ed una lesione ipodensa del sesto segmento epatico. Considerando la lunga storia di infezioni ricorrenti e l’indicazione ad investigare ulteriormente la lesione epatica, si optava per il drenaggio laparoscopico della lesione: aperta completamente la parete dell’ascesso, venivano drenati 550ml di liquido purulento la cui coltura evidenziava la presenza di Stafilococco aureo. Una ecografia del fegato intraoperatoria con sonda laparoscopica escludeva la presenza di una lesione resecabile del sesto segmento epatico e ne confermava la natura infiammatoria. La paziente veniva dimessa in terza giornata operatoria con terapia antibiotica mirata sull’antibiogramma. Nè febbre, nè dolore sono stati più riferiti ai successivi controlli a 1, 6, 12 e 24 mesi dall’intervento. Molti Autori ritengono che gli ascessi dell’ileopsoas possano essere controllati con terapia antibiotica ed eventualmente attraverso il drenaggio percutaneo, riservando il drenaggio chirurgico ai casi complessi o recidivanti. Tuttavia la letteratura non chiarisce se sia da preferire il drenaggio chirurgico con accesso open o laparoscopico. Nella nostra

  7. 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.

    Non-coalescence of two bodies of the same liquid and the suppression of contact between liquid drops and solid surfaces (nonwetting) has been studied through a pair of parallel investigations being conducted at the Georgia Institute of Technology and the Microgravity Research and Support (MARS) Center in Naples, Italy. Both non- coalescence and nonwetting may achieved by either: i) exploiting the mechanism of thermocapillary convection to drive a lubricating film of surrounding gas (air) into the space between the two liquid free surfaces (non-coalescence) or between the drop free surface and the solid (nonwetting); or ii) using the otherwise forced motion of the solid (or one liquid) surface to generate the lubricating film. These, and other types of related phenomena are discussed in our recent review article (Neitzel GP, Dell'Aversana P. 2002. Noncoalescence and nonwetting behavior of liquids. Annual Review of Fluid Mechanics 34: 267-89). This project was a continuation of earlier research on this subject and includes the possible uses of non-coalescing/wetting systems in technological applications.

    L’identificazione della reale sede del tutmore è essenziale per la formulazione di un adatto algoritmo nei cancri localizzati distalmente nel colon-retto (CTC). In questo studio è stata indagata l’efficacia della localizzazione di tumori distali del colon-retto di quattro metodologia: la colonscopia, la TAC, l’imaging della RMN, e la PET con fluoro-18-desossi-glicosio tomografia computerizzata (CT), analizzando retrospettivamente le cartelle cliniche di 156 pazienti affetti, Fluorodeoxyglucose -positron emission tomography scan da tumore del colon-sigma, della giunzione retto sigmoidea e del retto sottoposti a trattamento chirurgico. Per quanto riguarda l’accuratezza delle quattro metodologie essa è risultata simile: 74% per la clolonscopia, 67% per la TAC, 75% per la RMN e 74% con la PET. La colonscopia è risultata meno sensibile nei tumori retto-sigmoidei (33%) mentre la TAC è risultata meno sensibile (26%) e la RMN meno specifica (33%) per i tumori del retto. In conclusione, confermando l’importanza di poter localizzare correttamente i tumori distali del colon retto al fine di determinare le strategia più accurate del trattamento, le indagini preoperatorie non forniscono dati di adeguata accuratezza per i tumori colon rettali distali, e solo l’uso combinato di esse può accrescere il risultato cercato.

    The picture-word interference (PWI) paradigm and the Stroop color-word interference task are often assumed to reflect the same underlying processes. On the basis of a PRP study, Dell'Acqua et al. (Psychonomic Bulletin & Review, 14: 717-722, 2007) argued that this assumption is incorrect. In this article, we first discuss the definitions of Stroop- and picture-word interference. Next, we argue that both effects consist of at least four components that correspond to four characteristics of the distractor word: (1) response-set membership, (2) task relevance, (3) semantic relatedness, and (4) lexicality. On the basis of this theoretical analysis, we conclude that the typical Stroop effect and the typical PWI effect mainly differ in the relative contributions of these four components. Finally, the results of an interference task are reported in which only the nature of the target - color or picture - was manipulated and all other distractor task characteristics were kept constant. The results showed no difference between color and picture targets with respect to all behavioral measures examined. We conclude that the assumption that the same processes underlie verbal interference in color and picture naming is warranted.

    Sommario INTRODUZIONE: Tra le fistole arterovenose (FAV) acquisite vi sono quelle che si formano quale complicanza dell’esecuzione di una biopsia renale. CASO CLINICO: Gli autori riportano il caso di una paziente giunta in ambulatorio di ecografia nefrologica per l’esecuzione di un’ecografia dei reni e delle vie urinarie per un’ipertensione sistolica di I grado di recente insorgenza. Negli esami di laboratorio era presente microematuria con proteinuria <0.5 g/24 ore. La funzionalità renale risultava ai limiti inferiori della norma (FG 58 mL/min secondo la formula MDRD). L’esame ecografico evidenziava una formazione anecogena “arboriforme” centropielica a livello del rene sinistro suggestiva per idronefrosi. Il color Doppler mostrava viceversa presenza di flusso turbolento all’interno dell’area anecogena stessa, con flusso arterioso elevato e arterializzazione del flusso venoso all’analisi spettrale. La successiva angiografia renale selettiva confermava il sospetto ecografico di FAV mediorenale sinistra con pseudoaneurisma, conseguente ad una biopsia renale effettuata più di 10 anni prima presso altro Centro. Essendo la paziente in pieno benessere veniva consigliato un più stretto follow-up clinico-ecografico. DISCUSSIONE: Tra le malformazioni vascolari renali di non rara osservazione sono le FAV. Il caso descritto ribadisce l’importanza dell’impiego dell’eco color Doppler (ECD) nel sospetto di uropatia ostruttiva, per diagnosticare una FAV, specialmente nei pazienti già sottoposti a biopsia renale.

    The aim of this study was to characterize soils contaminated by different levels of heavy metals and hydrocarbons (Madonna Dell'Acqua, Pisa, Italy). The soils were chemically and biochemically analysed by measuring the standard chemical properties and some enzyme activities related to microbial activity (dehydrogenase activity) and the soil carbon cycle (total and extracellular beta-glucosidase activities). The metabolic capacities of soil microorganisms to degrade hydrocarbons through catechol 2,3-dioxygenase were also described. The microbial diversity of contaminated and uncontaminated soils was estimated by denaturing gradient gel electrophoresis (DGGE) of amplified 16S rDNA sequences. The PCR/single-strand conformation polymorphism (PCR/SSCP) method was used to estimate the genetic diversity of PAH-degrading genes in both contaminated and uncontaminated soils. A greater bacterial diversity and lower catechol 2,3-dioxygenase activity was detected in unpolluted soils. The complexity of the microbial community (Shannon and Simpson indices) as well as the dehydrogenase soil activity negatively correlated with contamination levels. The greatest PAH-degrading gene diversity and the most intense catechol 2,3-dioxygenase activity were found in the soils with the highest levels of hydrocarbons. Heavy metals and hydrocarbon pollution has caused a genetic and metabolic alteration in microbial communities, corresponding to a reduction in microbial activity. A multi-technique approach combining traditional biochemical methods with molecular-based techniques, along with some methodological improvements, may represent an important tool to expand our knowledge of the role of microbial diversity in contaminated soil.

    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.

    Background Researchers have demonstrated that people with aphasia (PWA) have preserved semantic knowledge (Dell et al., 1997; Jefferies & Lambon Ralph, 2006). However, Antonucci (2014) demonstrated that some PWA have impaired access to certain types of knowledge more than others. Yet, all these studies used single concepts. It has not been demonstrated whether PWA have difficulty accessing certain types of features within a discourse sample. Aims The main goals of this study were to determine if semantic knowledge and two category types were used differently within discourse produced by participants with anomic aphasia and healthy controls. Method & Procedures Participants with anomic aphasia (n=19) and healthy controls (n=19) told stories that were transcribed and coded for 10 types of semantic knowledge and two category types, living and nonliving things. Outcomes & Results A Poisson regression model was conducted. The results indicated a significant difference between the groups for the semantic knowledge types, sound and internal state, but no difference was found for category types. Yet the distribution of semantic knowledge and category types produced within the discourse samples were similar between the groups. Conclusion PWA might have differential access to certain types of semantic knowledge within discourse production, but it does not rise to the level of categorical deficits. These findings extend single-concept research into the realm of discourse. PMID:27429506

  15. Development of the Hebrew-Multidimensional Inventory of Dissociation (H-MID): a valid and reliable measure of pathological dissociation.

    2005-01-01

    The Multidimensional Inventory of Dissociation (MID; Dell, 2004b) has 168 dissociation items and 50 validity items. The MID assesses 14 major facets of dissociation, 23 symptoms of dissociation, and has 5 validity scales. The MID operationalizes (a) the subjective/ phenomenological domain of dissociation, and (b) 23 hypothesized symptoms of dissociative identity disorder (DID). This article describes the development of a Hebrew version of the MID (H-MID). In a sample of clinical and nonclinical research participants, the H-MID had strong internal consistency, temporal stability, and strong structural, convergent, discriminant, and construct validity. In addition, mean H-MID scores demonstrated incremental validity over the Hebrew Dissociative Experiences Scale (H-DES) by predicting an additional 17% of the variance in weighted trauma scores on the Traumatic Experiences Questionnaire (TEQ). Factor analysis of the H-MID extracted a single factor: dissociation. Both the MID and the subjective/phenomenological concept of pathological dissociation appear to have applicability not only in North America, but also in a heterogeneous Middle Eastern culture.

  16. Concept of healing of recurrent shoulder dislocation.

    2014-01-01

    This paper presents the main surgical techniques applied in the treatment of anterior recurrent shoulder dislocation, aiming the achievement of the normality of articulate movements. This was obtained by combining distinct surgical procedures, which allowed the recovery of a complete functional capacity of the shoulder, without jeopardizing the normality of movement, something that has not been recorded in the case of the tense sutures of the surgical procedures of Putti-Platt, Bankart, Latarjet, Dickson-O'Dell and others. The careful review of the methods applied supports the conclusion that recurrent shoulder dislocation can be cured, since cure has been obtained in 97% of the treated cases. However, some degree of limitation in the shoulder movement has been observed in most of the treated cases. Our main goal was to achieve a complete shoulder functional recovery, by treating simultaneously all of the anatomical-pathological lesions, without considering the so-called essential lesions. The period of post-operatory immobilization only last for the healing of soft parts; this takes place in a position of neutral shoulder rotation, since the use of vascular bone graft eliminates the need for long time immobilization, due to the shoulder stabilization provided by rigid fixation of the coracoid at the glenoid edge, as in the Latarjet's technique. Our procedure, used since 1959, comprises the association of several techniques, which has permitted shoulder healing without movement limitation. That was because of the tension reduction in the sutures of the subescapularis, capsule, and coracobraquialis muscles.

    In a recently published manuscript [Guidoboni, E., Boschi, E., 2006. Vesuvius before the 1631 eruption, EOS, 87(40), 417 and 423]; [Guidoboni, E. (Ed.), 2006. Pirro Ligorio, Libro di diversi terremoti (1571), volume 28, codex Ja II 15, Archivio di Stato di Torino, Edizione Nazionale delle Opere di Pirro Ligorio, Roma, De Luca, 261 pp], Pirro Ligorio gives a detailed description of the phenomena occurring in the crater area of Vesuvius volcano, in 1570-1571 and previous years. Here, these phenomena are interpreted as the first clearly documented signals of unrest of this volcanic system caused by the shallow emplacement of a magma batch and leading to the 1631 eruption. Our interpretation is mainly based on the present understanding of the fluid geochemistry of magmatic-hydrothermal systems. In this way, it is possible to conclude that: (i) incandescent rocks were present at the surface, with temperatures > 500 °C approximately and (ii) either a magmatic-dominated or a magmatic-hydrothermal-type of conceptual geochemical model applies to Vesuvius in 1570-1571 and preceding years. The Ligorio's picture represents the first clear evidence that the magma involved in the 1631 eruption was present under the volcano more than sixty years before the eruption. Moreover, its emplacement produced a series of phenomena which were clearly observed although not understood at that time. A similar phenomenological pattern should be easily detected and correctly interpreted at present or in the future.

    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.

    Il presente studio raffronta due gruppi di pazienti affetti da adenocarcinoma dolo-rettale, sottoposti rispettivamente a colectomia con tecnica open e a videolaparoscopia, mettendone in luce benefici e svantaggi. Si tratta di un’analisi retrospettiva: dal gennaio 2003 e il dicembre 2006 sono stati reclutati 54 pazienti; di questi 26 operati in laparotomia e 28 in laparoscopia. Per la chirurgia laparotomica la durata media dell’intervento è stata di 177.9 minuti (tempo chirurgico) e di 280.4 minuti (tempo di sala operatoria con un minimo di 110 ed un massimo di 360 minuti, con significative differenze in rapporto al tipo di chirurgia effettuata e la storia clinica del paziente. Per la chirurgia laparoscopica la durata media è stata di 293 minuti (range 135-520), con significative differenze dipendenti dalla porzione di intestino asportata. Il raffronto delle due tecniche chirurgiche, laparotomica versus lapsroscopica, ha rivelato alcune differenze. La durata della resezione è stata maggiore per la laparoscopia se confrontata con la tecnica tradizionale. Entrambi gli approcci rappresentano tecniche convenienti, sicure ed oncologicamente corrette. La laparoscopia mostra maggiori vantaggi in termini di controllo del dolore, assenza di estese cicatrici, riscontro di laparoceli e di degenza post operatoria comparata con la tecnica laparotomica.

    Sebbene la tecnica Mesh Plug rappresenti una procedura di indubbia efficacia nel trattamento dell’ernia inguinale, tuttora permangono dubbi in relazione alla storia naturale del plug. In particolare, il plug può andare incontro a coartazione (shrinkage) con formazione di un “meshoma” responsabile di una sintomatologia dolorosa cronica. Più raramente, il plug può migrare e provocare erosione delle strutture anatomiche circostanti. Nel passato sono stati proposti alcuni devices per cercare di risolvere il problema della migrazione; nessuno di questi, tuttavia, ha raggiunto la popolarità dei plug conici o a forma di fiore. Il presente lavoro riporta i risultati di uno studio pilota condotto con l’impiego di un nuovo device tridimensionale, il NeT Plug & Patch. I risultati dopo 12 mesi di follow-up, hanno dimostrato una ridotta incidenza di dolore postoperatorio e cronico, senza rischio di migrazione. Inoltre è stata registrata una compliance soddisfacente sia dei pazienti che degli operatori. La protesi NeT Plug & Patch ha dimostrato di poter realizzare un’ernioplastica semplice ed efficace per la riparazione dell’ernia inguinale.

    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.

The Project is focused on underwater archaeological surveys in ex quarry lakes, following the Rivers Padus and Sandalus between Voghiera, Gambulaga and Portomaggiore (Ferrara District). 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.

    Earthquake Early Warning Systems (EEWS) are potentially effective tools for risk mitigation in active seismic regions. The present study explores the possibility of predicting the macroseismic intensity within EEW timeframes using the squared velocity integral (IV2) measured on the early P wave signals, a proxy for the P wave radiated energy of earthquakes. This study shows that IV2 correlates better than the peak displacement measured on P waves with both the peak ground velocity and the Housner Intensity, with the latter being recognized by engineers as a reliable proxy for damage assessment. Therefore, using the strong motion recordings of the Italian Accelerometric Archive, a novel relationship between the parameter IV2 and the macroseismic intensity (IM) has been derived. The validity of this relationship has been assessed using the strong motion recordings of the Istituto Nazionale di Geofisica e Vulcanologia Strong Motion Data and Osservatorio Sismico delle Strutture databases, as well as, in the case of the MW 6, 29 May 2012 Emilia earthquake (Italy), comparing the predicted intensities with the ones observed after a macroseismic survey. Our results indicate that P wave IV2 can become a key parameter for the design of on-site EEWS, capable of proving real-time predictions of the IM at target sites.

  4. The Reflection Nebula in Orion

    Just weeks after NASA astronauts repaired the Hubble Space Telescope in December 1999, the Hubble Heritage Project snapped this picture of NGC 1999, a nebula in the constellation Orion. The Heritage astronomers, in collaboration with scientists in Texas and Ireland, used Hubble's Wide Field and Planetary Camera 2 (WFPC2) to obtain the color image. NGC 1999 is an example of a reflection nebula. Like fog around a street lamp, a reflection nebula shines only because the light from an imbedded source illuminates its dust; the nebula does not emit any visible light of its own. NGC 1999 lies close to the famous Orion Nebula, about 1,500 light-years from Earth, in a region of our Milky Way galaxy where new stars are being formed actively. NGC 1999 was discovered some two centuries ago by Sir William Herschel and his sister Caroline, and was cataloged later in the 19th century as object 1999 in the New General Catalogue. This data was collected in January 2000 by the Hubble Heritage Team with the collaboration of star-formation experts C. Robert O'Dell (Rice University), Thomas P. Ray (Dublin Institute for Advanced Study), and David Corcoran (University of Limerick).

    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.

    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.

    Surgical management of trapeziometacarpal osteoarthritis does not obey to strict rules. The use of interposition implants made of different materials leads to enrichment of surgeon's resources. This prospective study reports the radiological and clinical results of 45 patients treated by total trapeziectomy with polylactic acid interposition implant, with an average follow-up of 31 months. Thirty-seven surgical treatments were carried out after ineffective medical treatment. According to Dell classification, there were five stages II, 30 stages III and two stages IV. Mean age was 66 years. Dominant side was involved in 60%. Thumbs were pain free at 5 months in average and 81% of the patients reported good results (Alnot stages 0 and 1). The average opposition was 9.1/10, the average M1M2 angle was 40°, and the average key pinch strength was 4.4 kg. Six patients suffered from sympathetic dystrophy but neither infection nor local inflammatory reaction was observed. Collapse of the trapezium space was constant and the trapezium space ratio was 76% at the follow-up. Seventy-five per cent of patients returned back to their occupation. The satisfaction rate was 89%. The radioclinical results were very good in our series. The interposition of polylactic acid implant permits to avoid the presumed complications of tendon harvesting, and those of other types of material used in the same indication. Its safety seems excellent.

  8. Modeling of Radiative Transfer in Protostellar Disks

    This program implements a spectral line, radiative transfer tool for interpreting Spitzer Space Telescope observations by matching them with models of protostellar disks for improved understanding of planet and star formation. The Spitzer Space Telescope detects gas phase molecules in the infrared spectra of protostellar disks, with spectral lines carrying information on the chemical composition of the material from which planets form. Input to the software includes chemical models developed at JPL. The products are synthetic images and spectra for comparison with Spitzer measurements. Radiative transfer in a protostellar disk is primarily affected by absorption and emission processes in the dust and in molecular gases such as H2, CO, and HCO. The magnitude of the optical absorption and emission is determined by the population of the electronic, vibrational, and rotational energy levels. The population of the molecular level is in turn determined by the intensity of the radiation field. Therefore, the intensity of the radiation field and the population of the molecular levels are inter-dependent quantities. To meet the computational challenges of solving for the coupled radiation field and electronic level populations in disks having wide ranges of optical depths and spatial scales, the tool runs in parallel on the JPL Dell Cluster supercomputer with C++ and Fortran compiler with a Message Passing Interface. Because this software has been developed on a distributed computing platform, the modeling of systems previously beyond the reach of available computational resources is possible.

    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.

    Q is an unmanned ground vehicle designed to compete in the Autonomous and Navigation Challenges of the AUVSI Intelligent Ground Vehicle Competition (IGVC). Built on a base platform of a modified PerMobil Trax off-road wheel chair frame, and running off a Dell Inspiron D820 laptop with an Intel t7400 Core 2 Duo Processor, Q gathers information from a SICK laser range finder (LRF), video cameras, differential GPS, and digital compass to localize its behavior and map out its navigational path. This behavior is handled by intelligent closed loop speed control and robust sensor data processing algorithms. In the Autonomous challenge, data taken from two IEEE 1394 cameras and the LRF are integrated and plotted on a custom-defined occupancy grid and converted into a histogram which is analyzed for openings between obstacles. The image processing algorithm consists of a series of steps involving plane extraction, normalizing of the image histogram for an effective dynamic thresholding, texture and morphological analysis and particle filtering to allow optimum operation at varying ambient conditions. In the Navigation Challenge, a modified Vector Field Histogram (VFH) algorithm is combined with an auto-regressive path planning model for obstacle avoidance and better localization. Also, Q features the Joint Architecture for Unmanned Systems (JAUS) Level 3 compliance. All algorithms are developed and implemented using National Instruments (NI) hardware and LabVIEW software. The paper will focus on explaining the various algorithms that make up Q's intelligence and the different ways and modes of their implementation.

    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.

    Un uomo di 60 anni con ischemia mesenterica cronica (CMI) è stato trattato con una terapia ‘bridge’ verso una terapia di chirurgia open tradizionale, mediante stenting dell’arteria mesenterica superiore (SMA). Al follow-up a 5 mesi lo stent della SMA è andato incontro ad occlusione. Durante questo periodo ‘bridge’ il paziente ha migliorato le sue condizioni generali e il suo indice di massa corporea (BMI) è incrementato da 18 a 22. Il paziente è stato sottoposto successivamente ad intervento chirurgico di bypass iliaco-SMA in configurazione ‘Cloop’. Al follow-up a 6 mesi il bypass è pervio, il paziente non riferisce sintomatologia di CMI ed il suo BMI è di 25. Il trattamento endovascolare non ha precluso una successiva riparazione chirurgica e può essere impiegato in maniera sicura come terapia ‘bridge’. Un miglioramento delle condizioni cliniche, anche durante un limitato periodo ‘bridge’, può migliorare i risultati della terapia chirurgica tradizionale.

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

    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.

    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.

    MCNP4B was released in February 1997 with significant enhancements to electron/photon transport methods. These enhancements have been verified against a wide range of published electron/photon experiments, spanning high energy bremsstrahlung production to electron transmission and reflection. Three sets of bremsstrahlung experiments were simulated. The first verification calculations for bremsstrahlung production used the experimental results in Faddegon for 15 MeV electrons incident on lead, aluminum, and beryllium targets. The calculated integrated bremsstrahlung yields, the bremsstrahlung energy spectra, and the mean energy of the bremsstrahlung beam were compared with experiment. The impact of several MCNP tally options and physics parameters was explored in detail. The second was the experiment of O`Dell which measured the bremsstrahlung spectra from 10 and 20.9 MeV electrons incident on a gold/tungsten target. The final set was a comparison of relative experimental spectra with calculated results for 9.66 MeV electrons incident on tungsten based on the experiment of Starfelt and Koch. The transmission experiments of Ebert were also studied, including comparisons of transmission coefficients for 10.2 MeV electrons incident on carbon, silver, and uranium foils. The agreement between experiment and simulation was usually within two standard deviations of the experimental and calculational errors.

    A 10-year-old female cat was brought to Istituto Zooprofilattico Sperimentale delle Regioni Lazio e Toscana for post-mortem examination. The animal used to live, together with 26 other cats, in the big terrace of an apartment at the 8th floor in Rome; and was always fed with industrial pet food. Anamnesis referred balance troubles, vomit and convulsions, during a couple of days, followed by sudden death. At necropsy, the cat presented mucoid rhinitis, purulent tracheitis, small areas of pneumonia, dark spots in the liver, catarrhal-hemorrhagic gastritis, fibrinous enteritis and meningeal hyperemia. Thoracic and abdominal cavities were completely invaded by hundreds of larval stages of cestodes. The same parasites were also included in nodules in pancreatic, lung and kidney parenchyma. Microscopic examination of parasites allowed their identification as larval stages (metacestodes) of cestodes of the genus Mesocestoides. The molecular genotyping of the metacestodes indicates a close relationship with members of the genus Mesocestoides, although a significant variation was found with respect to the available sequences of other species of the genus.

    Positron emission tomography (PET) of brain amyloid is a technology that has been approved by Food and Drug Administration and European Medical Agency, but its clinical utility in medical practice requires careful definition. To provide guidance to italian dementia care practitioners, patients, and caregivers, a group of experts from "Associazione Italiana di Medicina Nucleare" (AIMN), "Associazione Italiana di Psicogeriatria" (AIP) and "Società Italiana per lo Studio delle Demenze" (SINDEM) convened the Italian Interdisciplinary Working Group on Amyloid Imaging. The Working Group considered a range of clinical scenarios in which amyloid PET should be recommended. Peer-reviewed, published literature was searched to ascertain available evidence relevant to these recommendations. Although empirical evidence of impact on clinical outcomes is not yet available, a set of specific recommended use criteria were agreed to define the types of patients and clinical circumstances in which amyloid PET could be used. Both correct and incorrect uses were considered and formulated. Because both dementia care and amyloid-PET technology are in active development, these recommendations will require periodic reassessment.

    In Mandarin Chinese, speakers benefit from fore-knowledge of what the first syllable but not of what the first phonemic segment of a disyllabic word will be (Chen, J.-Y., Chen, T.-M. & Dell, 2002), contrasting with findings in English, Dutch, and other Indo-European languages, and challenging the generality of current theories of word production. In this article, we extend the evidence for the language difference by showing that failure to prepare onsets in Mandarin (Experiment 1) applies even to simple monosyllables (Experiments 2-4), and confirm the contrast with English for comparable materials (Experiments 5, 6). We also provide new evidence that Mandarin speakers do reliably prepare tonally unspecified phonological syllables (Experiment 7). To account for these patterns, we propose a language general proximate units principle whereby intentional preparation for speech as well as phonological-lexical coordination are grounded at the first phonological level below the word at which explicit unit selection occurs. The language difference arises because syllables are proximate units in Mandarin Chinese, whereas segments are proximate in English and other Indo-European languages. The proximate units perspective reconciles the aspiration toward a language general account of word production with the reality of substantial cross-linguistic differences. PMID:20149354

    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.

    L’osteocondroma è una neoplasia benigna che nel distretto cranio-facciale colpisce spesso il corpo ed il ramo mandibolare e soltanto di rado può interessare il processo coronoide e l’arco zygomatico. In questo articolo descriviamo un raro caso di osteocondroma isolato dell’osso zygomatico trattato mediante approccio chirurgico intraorale endoscopicamente assistito ed in letteratura non sono riportati altri casi di questa patologia trattati con procedure endoscopicamente assistite. Una donna caucasica di cinquantadue anni, è stata osservata nel nostro reparto nel mese di marzo del 2012, la paziente lamentava dolore in regione zygomatica destra. La tomografia computerizzata (TC) del distretto osseo interessato mostrava una lesione sessile non definita. Il sospetto diagnostico è stato di osteocondroma. L’intervento è stato realizzato in anestesia generale mediante approccio intraorale endoscopicamente assistito. All’esame istologico del campione operatorio è stata confermata la diagnosi di osteocondroma. Nell’immediato post operatorio la paziente non ha presentato edema, dolore o febbre. L’uso dell’endoscopia nel trattamento chirurgico di questa patologia quindi ha consentito di ottenere una maggiore precisione e una maggiore rispetto delle strutture anatomiche. L’approccio intraorale ci garantisce l’assenza di cicatrici visibili e l’ausilio dell’endoscopia ci consente di avere una migliore visione di tutte le strutture anatomiche, una buona gestione della patologia riducendo quindi il rischio di complicanze intraoperatorie quali: fratture patologiche e lesioni del VII nervo cranico.
