    The activity concentrations of uranium and toxic elements in Dei-Dei borehole, Kubwa borehole, Water Board and hand-dug well water samples in Abuja area were measured using inductively coupled plasma mass spectrometry (ICP-MS) system. The results obtained were used to calculate human radiological risk over lifetime consumption by the inhabitants in the area. The activity concentrations of 238U in all the water supplies for drinking ranges from 0.849 mBq L-1 to 2.699 mBq L-1 with the highest value of 2.699 mBq L-1 noted at Dei-Dei borehole whereas the lowest value of 0.849 mBq L-1 was noted in Kubwa borehole. The highest annual effective dose from natural 238U in all the water samples was found in Dei-Dei borehole with a value of 8.9×10-5 mSv y-1 whereas the lowest value was noted in Kubwa borehole with a value of 2.8×10-5 mSv y-1. The radiological risks for cancer mortality were found distinctly low, with the highest value of 1.01×10-7 reported at Dei-Dei borehole compared to Kubwa borehole with a value of 3.01×10-8. The cancer morbidity risk was noted higher in Dei-Dei borehole with a value of 1.55×10-7 whereas lower value of 4.88×10-9 was reported in Kubwa borehole. The chemical toxicity risk of 238U in drinking water over a lifetime consumption has a value of 0.006 μg kg-1 day-1 in Dei-Dei borehole whereas lower value of 0.002 μg kg-1 day-1 was found in Kubwa borehole. Measured lead (Pb) and chromium (Cr) concentrations reported higher in Water Board compared to Dei-Dei and Kubwa borehole samples. Significantly, this study inferred that the 238U concentrations originate from granitic strata of the tectonic events in the area; thus, there was a trend of diffusion towards north to south and re-deposition towards Dei-Dei area.

  8. Purification, characterization, and specificity of dextranase inhibitor (Dei) expressed from Streptococcus sobrinus UAB108 gene cloned in Escherichia coli.

    PubMed Central

    Sun, J W; Wanda, S Y; Curtiss, R

    1995-01-01

    The dextranase inhibitor gene (dei) from Streptococcus sobrinus UAB108 was previously cloned, expressed, and sequenced. Its gene product (Dei) has now been purified as a single band with apparent molecular mass of 43 kDa, as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The specific activity of Dei increased 121-fold upon purification. Most Dei activity (91.2%) was located in the periplasmic fraction from recombinant Escherichia coli cells. Dei competitively inhibits dextranase (Dex). This competitive inhibition mechanism has been further shown by detection and recovery of the intermediate enzyme-inhibitor (Dex-Dei) complex by gel filtration technology using fast protein liquid chromatography. Calibration of their molecular masses indicated that native Dei exists as a tetramer, Dex exists as dimer, and the Dex-Dei complex consists of two Dex molecules with two Dei molecules. Deletion analysis indicates that the intact Dei molecule is essential for Dei activity but not for glucan binding and immune cross-reaction. Dei is a special kind of glucan-binding protein with ability to inhibit Dex with high specificity. It can inhibit endogenous Dex, which can make more branches in glucan with the cooperation of the glucosyltransferase GTF-I. This inhibition cause the accumulation of water-soluble glucan. The latter reaction product can inhibit plaque formation and adherence of the mutans group of streptococcal cells. Dei derived from S. sobrinus UAB108 can inhibit only Dex from S. sobrinus (serotypes d and g), S. downei (previously S. sobrinus, serotype h), and S. macacae (serotype h). This finding suggests that Dei is another important protein existing in some serotypes of the mutans group of streptococci which participates in sucrose metabolism through its interaction with Dex.

    We explored diffraction enhanced imaging (DEI) in both planar and computed tomography (CT) modes for early detection of beta amyloid deposition, a hallmark feature in Alzheimer's disease (AD). Since amyloid plaques precede clinical symptoms by years, their early detection is of great interest. These findings were correlated with results from synchrotron infrared microspectroscopic imaging and X-ray fluorescence microscopy, to determine the secondary structure of the amyloid beta protein and metal concentration in the amyloid plaques, respectively.

    Different modalities for imaging cancer-bearing breast tissue samples are described and compared. The images include clinical mammograms and computed tomography (CT) images, CT images with partly coherent synchrotron radiation (SR), and CT and radiography images taken with SR using the diffraction enhanced imaging (DEI) method. The images are evaluated by a radiologist and compared with histopathological examination of the samples. Two cases of lobular carcinoma are studied in detail. The indications of cancer are very weak or invisible in the conventional images, but the morphological changes due to invasion of cancer become pronounced in the images taken by the DEI method. The strands penetrating adipose tissue are seen clearly in the DEI-CT images, and the histopathology confirms that some strands contain the so-called 'Indian file' formations of cancer cells. The radiation dose is carefully measured for each of the imaging modalities. The mean glandular dose (MGD) for 50% glandular breast tissue is about 1 mGy in conventional mammography and less than 0.25 mGy in projection DEI, while in the clinical CT imaging the MGD is very high, about 45 mGy. The entrance dose of 95 mGy in DEI-CT imaging gives rise to an MGD of 40 mGy, but the dose may be reduced by an order of magnitude, because the contrast is very large in most images.

    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.

  18. Gas hazard assessment in a densely inhabited area of Colli Albani Volcano (Cava dei Selci, Roma)

    NASA Astrophysics Data System (ADS)

    2003-04-01

    The northwestern flank of the Colli Albani, a Quaternary volcanic complex near Rome, is characterised by high pCO 2 values and Rn activities in the groundwater and by the presence of zones with strong emission of gas from the soil. The most significant of these zones is Cava dei Selci where many houses are located very near to the gas emission site. The emitted gas consists mainly of CO 2 (up to 98 vol%) with an appreciable content of H 2S (0.8-2%). The He and C isotopic composition indicates, as for all fluids associated with the Quaternary Roman and Tuscany volcanic provinces, the presence of an upper mantle component contaminated by crustal fluids associated with subducted sediments and carbonates. An advective CO 2 flux of 37 tons/day has been estimated from the gas bubbles rising to the surface in a small drainage ditch and through a stagnant water pool, present in the rainy season in a topographically low central part of the area. A CO 2 soil flux survey with an accumulation chamber, carried out in February-March 2000 over a 12 000 m 2 surface with 242 measurement points, gave a total (mostly conductive) flux of 61 tons/day. CO 2 soil flux values vary by four orders of magnitude over a 160-m distance and by one order of magnitude over several metres. A fixed network of 114 points over 6350 m 2 has been installed in order to investigate temporal flux variations. Six surveys carried out from May 2000 to June 2001 have shown large variations of the total CO 2 soil flux (8-25 tons/day). The strong emission of CO 2 and H 2S, which are gases denser than air, produces dangerous accumulations in low areas which have caused a series of lethal accidents to animals and one to a man. The gas hazard near the houses has been assessed by continuously monitoring the CO 2 and H 2S concentration in the air at 75 cm from the ground by means of two automatic stations. Certain environmental parameters (wind direction and speed; atm P, T, humidity and rainfall) were also

    In the framework of the extensive study on the wood painting "Madonna dei fusi" attributed to Leonardo da Vinci, Ion Beam Analysis (IBA) techniques were used at the Florence accelerator laboratory to get information about the elemental composition of the paint layers. After a brief description of the basic principle and the general features of IBA techniques, we will illustrate in detail how the analysis allowed us to characterise the pigments of original and restored areas and the substrate composition, and to obtain information about the stratigraphy of the painting, also providing an estimate of the paint layer thickness.

  20. Near-surface geophysical investigations inside the cloister of the historical palace 'Palazzo dei Celestini' in Lecce, Italy

    2010-06-01

    Non-invasive geophysical investigations are usually the only way to gain information on subsurface properties that can affect the stability of historical structures and accelerate degradation processes. A combined multi-frequency ground-penetrating radar (GPR) geoelectrical and induced polarization (IP) survey was performed in the cloister of 'Palazzo dei Celestini', Lecce, southern Italy, in order to investigate possible subsurface causes of deterioration. The historical palace was originally a convent connected to the Basilica of 'Santa Croce' and is now the head office of the Province of Lecce Administration and the Prefecture. Built in Pietra Leccese, a fine-grained calcarenite, Santa Croce and Palazzo dei Celestini is the most famous baroque architectural complex of the historical centre of Lecce. The high capillarity of the building material causes deterioration problems especially at some altars of the church and in the lower portion of the walls and pillars of the monumental building. The integrated geophysical survey yielded a detailed description of the shallow stratigraphical and hydro-geological setting of the area and an accurate location of ancient and modern drainage systems. The geophysical information was essential for identifying natural or anthropogenic causes of the local increase in subsoil moisture that could accelerate the degradation process and for developing effective remediation activities.

    Glioblastoma multiforme (GBM) is the commonest and most aggressive primary brain tumor in humans. The high rate of tumor recurrence results in a poor prognosis despite multimodality treatment. One reason for high rate of recurrence is the invasive nature of the tumor into the surrounding normal brain tissue or multifocal occurrence at sites remote from that of the primary tumor establishment. Existing imaging demonstrates the primary tumor but fail to show the residual tumor microaggregates left behind following initial treatment. In this study, we employed diffraction-enhanced imaging (DEI) in an attempt to find an imaging modality that will provide visualization of residual disease that is not be apparent on MRI or CT scans.

    Morphometric parameters, acquired notoriety mainly after the Drainage Density proposition (Horton 1932, 1945) and after they were applied by geomorphologists on the perspective to understand landscape functionalities, quantifying their characteristics through parameters and indexes. After the drainage density, many other parameters which describe the basin characteristics, behavior and dynamics have been proposed. Among them, for example, the DEI was proposed by Coelho Netto and contributors during the 80's, while they were seek to understand the hydrological and erosive dynamics on Bananal river basin (Brazilian Southeastern). Through this investigations the DEI was created, revealing the importance of parameters as hollow and drainage density, conjugated to the topographic gradient (Meis et al. 1982) who prosecute controls on the water flow efficiency along the hollows in order to activate the regressive erosion of the main channel. Later on this index was applied on the basin scale in several works developed in mountainous regions, showing a remarkable correlation with the occurrence of landslides such as showed by Coelho Netto et al. (2007); that posteriorly use this index as one of the components of the landslide susceptibility map for the Tijuca Massif, located in Rio de Janeiro Municipality. This work aims to establish patterns of the DEI index values (applied to mountainous low order basins) and the relationship on the occurrence of Debriflows or shallow translational slides. For this, the DEI index was applied on 4 different study areas located on the Southeastern mountainous region of Brazil to address deeply the connection between the index and the occurrence of landslides of different types applied for first and second order basins. The major study area is the Córrego Dantas Basin, situated in Nova Friburgo municipality (RJ), which is a 53 km² basin was affected by 327 landslides caused by a heavy rainfall on January 2011; Coelho Netto et al.

    The paper describes how new digital methodologies can be used within the field of Cultural Heritage, not only with the aim of documenting the actual state of an architecture but to review the past transformations it has undergone, conserving and representing these histories as well. The premise to conservation and enhancement of our Heritage is a deep study in terms of position, shape, colour, and also of the historical and artistic features. Survey methods have acquired data acquisition techniques in line with technological progress: today's electronic and IT technologies, that are the tools of modern Geomatics, allow the effective survey and representation of 3D objects, from architectural structures to sculptures or archaeological finds. Over the last few years, the methodologies of acquisition and integrated representation for 3D patrimony documentation have developed and consolidated considerably: the possibilities of the digital realm can augment the understanding and the valorisation of a monument. The specific case offered in the present paper, Ca' Venier dei Leoni, the palace where is the Guggenheim Museum in Venice, is a significant example. It suggests not only the theme of the "no longer existing", or better never built, but also the opportunity to formulate hypotheses regarding its implementation and the impact that the palace would have had in the Venetian contest.

    3D measurement and modelling have been traditionally applied to statues, buildings, archeological sites or similar large structures, but rarely to paintings. Recently, however, 3D measurements have been performed successfully also on easel paintings, allowing to detect and document the painting's surface. We used 3D models to integrate the results of various 2D imaging techniques on a common reference frame. These applications show how the 3D shape information, complemented with 2D colour maps as well as with other types of sensory data, provide the most interesting information. The 3D data acquisition was carried out by means of two devices: a high-resolution laser micro-profilometer, composed of a commercial distance meter mounted on a scanning device, and a laser-line scanner. The 2D data acquisitions were carried out using a scanning device for simultaneous RGB colour imaging and IR reflectography, and a UV fluorescence multispectral image acquisition system. We present here the results of the techniques described, applied to the analysis of an important painting of the Italian Reinassance: `Madonna dei Fusi', attributed to Leonardo da Vinci.

  5. Mapping transitions between healthy and pathological lesions in human breast tissues by diffraction enhanced imaging computed tomography (DEI-CT) and small angle x-ray scattering (SAXS)

    2014-02-01

    In this work we have combined the DEI-CT and SAXS technique to study the transition between healthy and pathological breast tissues, which include benign and malignant lesions. The ability of DEI-CT to enhance the contrast between soft tissues was used to localize the tumor region in the sample. Then, the tumor region and its surroundings were scanned by SAXS in order to map the changes promoted by the neoplasias at nano-level.It was clearly observed that pathological tissues present distinguishable SAXS scattering profiles from those of normal tissue. These differences are mainly related to changes in arrangement and diameter of collagen fibrils, evaluated by the higher order of reflection peaks of these fibrils. Differences related to the peak intensities and the total scattered intensity were found by comparing the healthy and pathological regions. The 2nd order of collagen reflection arises only in the healthy region neighboring the benign lesion. A broader peak at q=0.16 nm-1 seems to characterize the malignant lesions. Finally, based on this information, the transition between healthy and pathological human breast tissues was mapped which allowed to get insights into the changes promoted by tumors during growth and progression.

  6. Bulk rock composition and geochemistry of olivine-hosted melt inclusions in the Grey Porri Tuff and selected lavas of the Monte dei Porri volcano, Salina, Aeolian Islands, southern Italy

    The Aeolian Islands are an arcuate chain of submarine seamounts and volcanic islands, lying just north of Sicily in southern Italy. The second largest of the islands, Salina, exhibits a wide range of compositional variation in its erupted products, from basaltic lavas to rhyolitic pumice. The Monte dei Porri eruptions occurred between 60 ka and 30 ka, following a period of approximately 60,000 years of repose. The bulk rock composition of the Monte dei Porri products range from basaltic-andesite scoria to andesitic pumice in the Grey Porri Tuff (GPT), with the Monte dei Porri lavas having basaltic-andesite compositions. The typical mineral assemblage of the GPT is calcic plagioclase, clinopyroxene (augite), olivine (Fo72−84) and orthopyroxene (enstatite) ± amphibole and Ti-Fe oxides. The lava units show a similar mineral assemblage, but contain lower Fo olivines (Fo57−78). The lava units also contain numerous glomerocrysts, including an unusual variety that contains quartz, K-feldspar and mica. Melt inclusions (MI) are ubiquitous in all mineral phases from all units of the Monte dei Porri eruptions; however, only data from olivine-hosted MI in the GPT are reported here. Compositions of MI in the GPT are typically basaltic (average SiO2 of 49.8 wt %) in the pumices and basaltic-andesite (average SiO2 of 55.6 wt %) in the scoriae and show a bimodal distribution in most compositional discrimination plots. The compositions of most of the MI in the scoriae overlap with bulk rock compositions of the lavas. Petrological and geochemical evidence suggest that mixing of one or more magmas and/or crustal assimilation played a role in the evolution of the Monte dei Porri magmatic system, especially the GPT. Analyses of the more evolved mineral phases are required to better constrain the evolution of the magma.

    2015-02-01

    We present the results of a point-cloud-based survey deriving from the use of image-based techniques, in particular with multi-image monoscopic digital photogrammetry systems and software, the so-called "structure-from-motion" technique. The aim is to evaluate the advantages and limitations of such procedures in architectural surveying, particularly in conditions that are "at the limit". A particular case study was chosen: the courtyard of Palazzo dei Capitani del Popolo in Ascoli Piceno, Italy, which can be considered the ideal example due to its notable vertical, rather than horizontal, layout. In this context, by comparing and evaluating the different results, we present experimentation regarding this single case study with the aim of identifying the best workflow to realise a complex, articulated set of representations—using 3D modelling and 2D processing—necessary to correctly document the particular characteristics of such an architectural object.

  9. Superimposed positive and negative inversion of the syn-rift fault network preserved in the Montagna dei Fiori Anticline, Central Apennines, Italy

    Syn-rift tectono-sedimentary inheritance is common in thrust-related anticlines exposed in most foreland thrust-fold belts worldwide. Inherited extensional faults provide mechanical weakness zones that typically undergo positive inversion during contraction. This unavoidably has an impact on the evolution of contractional folds. Moreover, duplexing and imbrication of thrust sheets typically produce gravitational instability of inherited fault patterns and negative inversion can be triggered in the late stages of fault-fold interaction. Such polyphase evolutionary histories can deeply influence deformation and fluid flow patterns in fault-related folds and therefore can strongly influence the distribution of structurally controlled processes such as dolomitization. In this contribution we present the results obtained from a multidisciplinary study of the tectono-sedimentary pattern and paleofluid history in carbonates exposed in the Montagna dei Fiori Anticline, at the mountain front of the Central Apennines (central Italy), where the occurrence of both syn-rift fault zones and related sediments has been previously described. Detailed mapping of the central part of the anticline, bed-perpendicular logging of syn-rift and post-rift strata, structural, petrographical, geochemical, microthermometrical, and petrophysical analyses were used to reconstruct the evolution of this anticline, starting from the pre-orogenic architecture up to its subsequent orogenic reworking. These data reveal: (1) the pre-orogenic tectono-sedimentary architecture of a folded Jurassic fault network; (2) multiple superimposition of extensional and contractional episodes of deformation on the same fault zones; (3) the presence of at least one main dolomitization episode, the timing of which is still being deciphered; (4) demonstrate the causal link between faulting and dolomitization, which favoured formation of dolostones along fault zones, particularly in the intersection/abutting areas

La condizione metabolica e neuro-endocrino cui è sottoposto il feto è rilevante per la “programmazione metabolica”. E’ dimostrata inoltre l’importanza delle modalità di allattamento e divezzamento con particolare interesse per l’assunzione di proteine nel controllo dei fattori di rischio cardiovascolari. La corretta distribuzione di macronutrienti (lipidi, proteine e carboidrati) dall’infanzia all’adolescenza favorisce una crescita corretta e risulta utile a prevenire l’insorgenza dei determinanti di rischio di malattia cardiovascolare in età adulta. Nella presente review verrà esaminato l’impatto della nutrizione dalle più precoci fasi delle vita sul rischio cardiovascolare. PMID:23259704

    An Environmental Impact Statement (EIS) is being prepared which considers alternate means for solidifying the high level liquid wastes (HLLW) at the Western New York Nuclear Service Center (WNYNSC). For this purpose three basic scenarios were considered. In the first scenario, the HLLW is converted into terminal waste form of borosilicate glass. Before vitrification, the non-radioactive chemical salts are separated from the radioactive and transuranic (TRU) constituents in the HLLW. In the second scenario, the HLLW is converted into an intermediate form-fused salt. The stored HLLW is dewatered and melted and the solids are transported to a Department of Energy (DOE) site. The fused salt will be processed of the DOE site at a later date where it will be converted to a vitrified form in a facility that will be constructed to treat HLLW stored at that site. The vitrified salt will be eventually removed for permanent disposal at a Federal repository. In the third scenario, the HLLW is solidified in the existing HLLW storage tanks with cement and returned for on-site disposal in the existing tanks or additional tanks as needed to accommodate the volume. To support the EIS, the costs to accomplish each of the alternatives is provided. The purpose of this cost estimate is to provide a common basis to evaluate the expenditures required to immobilize the HLLW presently stored at the WNYNSC. (DMC)

    2011-01-01

    In 1776, the Sienese botanist Biagio Bartalini (1750-1822) published a catalogue of wild plants growing around Siena, adding an appendix on fossils found in the same area, that is the first monograph on Sienese fossils and one of the first works of its kind in Italy. This paper provides tentative identifications of the species and an analysis of the value and meaning of Bartalini's work. The catalogue reports 72 species, each denoted by a list of names applied to analogous living taxa. Identification of single entities is extremely problematical because it can only be attempted through analysis of the literature, since the original material cannot be traced. The most interesting report is the first record of a Euro-Mediterranean Pliocene species of Sthenorytis (Gastropoda, Epitoniidae). Though important, the catalogue is incomplete, with oversights and mistakes, suggesting little familiarity with the subject. Shortcomings include some inconsistencies in the species sequence, the report of giant clams and the absence of molluscs ubiquitous in the Sienese Pliocene and sharks. Nor is it true that it is the first Italian palaeontological work in which binomial nomenclature was used, as sometimes claimed. PMID:21560438

    Accidents could occur during the transportation of spent nuclear fuel and high-level radioactive waste. This paper describes the risks and consequences to the public from accidents that are highly unlikely but that could have severe consequences. The impact of these accidents would include those to a collective population and to hypothetical maximally exposed individuals (MEIs). This document discusses accidents with conditions that have a chance of occurring more often than 1 in 10 million times in a year, called ''maximum reasonably foreseeable accidents''. Accidents and conditions less likely than this are not considered to be reasonably foreseeable.

    1998-01-01

    The incorporation into Italian legislation of the European Community directives on the improvement of health and safety at work has promoted a vast effort in order to revise the surveillance approach in many facilities, including hospitals. At the S. Gerardo Hospital in Monza, the required risk evaluation was performed in 1995. The paper here reports the results of environmental and work organization inspection, literature review and the proposal of a surveillance program. S. Gerardo Hospital is a large facility with 2,547 employees. Major structural problems are associated with fire prevention and the continuous change required for the development of a modern hospital. Relevant risk in health care are: biological risk, in particular hepatitis B and AIDS virus, teratogenic viruses (rubella, cytomegalovirus and varicella-zoster) and the renewed possibility of tuberculosis infection, often multi-drug resistant; chemical hazards, in particular use and exposure to antineoplastic and antiviral agents, sterilants like ethylene oxide and formaldheyde; physical risk, well-known for ionizing radiations, but important also for non-ionizing radiations; manual lifting (patients in particular) which makes nurses one of the occupations most affected by low back pain; psycho-social risk, with particular reference to stress in emergency departments and everywhere a strong psychological engagement is required. Also the risk of non-health personnel, office areas, food preparation, housekeeping, maintenance, central supplies and laundry was assessed. Health surveillance programs for the exposed and preventive medicine programs according international standards for all workers are presented. PMID:9608194

    Conventional mammographic image contrast is derived from x-ray absorption, resulting in breast structure visualization due to density gradients that attenuate radiation without distinction between transmitted, scattered, or refracted x-rays. Diffraction-enhanced imaging (DEI) allows for increased contrast with decreased radiation dose compared to conventional mammographic imaging because of monochromatic x-rays, its unique refraction-based contrast mechanism, and excellent scatter rejection. However, a lingering drawback to the clinical translation of DEI has been the requirement for synchrotron radiation. The authors laboratory developed a DEI prototype (DEI-PR) using a readily available tungsten x-ray tube source and traditional DEI crystal optics, providing soft tissue images at 60 keV. Images of full-thickness human breast tissue specimens were acquired on synchrotron-based DEI (DEI-SR), DEI-PR, and digital mammographic systems. A panel of expert radiologists evaluated lesion feature visibility and correlation with pathology after receiving training on the interpretation of refraction contrast mammographic images. For mammographic features (mass, calcification), no significant differences were detected between the DEI-SR and DEI-PR systems. Benign lesions were perceived as better seen by radiologists using the DEI-SR system than the DEI-PR system at the [111] reflectivity, with generalizations limited by small sample size. No significant differences between DEI-SR and DEI-PR were detected for any other lesion type (atypical, cancer) at either crystal reflectivity. Thus, except for benign lesion characterizations, the DEI-PR system's performance was roughly equivalent to that of the traditional DEI system, demonstrating a significant step toward clinical translation of this modality for breast cancer applications.

    OBJECTIVE--To examine the role of serum cholesterol in acute myocardial infarction in a population of patients with no history of coronary heart disease and to establish the nature of this association, the degree of risk, and the possible interaction between serum cholesterol and other major risk factors for acute myocardial infarction. DESIGN--Case-control study. SETTING--90 hospitals in northern, central, and southern Italy. PATIENTS--916 consecutive cases of newly diagnosed acute myocardial infarction and 1106 hospital controls admitted to hospital with acute conditions not related to known or suspected risk factors for coronary heart disease. DATA COLLECTION--Data were collected with a structured questionnaire and blood samples were taken by venepuncture as soon as possible after admission to hospital from cases and controls. Blood cholesterol concentrations were available for 614 cases and 792 controls. RESULTS--After adjustment by logistic regression for sex, age, education, geographical area, smoking status, body mass index, history of diabetes and hypertension, and family history of coronary heart disease the estimated relative risks of acute myocardial infarction for quintiles of serum cholesterol (from lowest to highest) were 2.3 (95% confidence interval (CI) 1.6 to 3.4), 3.1 (95% CI 2.1 to 4.6), 4.1 (95% CI 2.8 to 6.0), and 5.2 (95% CI 3.5 to 7.7). The estimated relative risk across selected covariates increased from the lowest to the highest quintile of serum cholesterol particularly for men, patients under 55 years of age, and smokers. When the possible interaction of known risk factors with serum cholesterol was examined, smoking habits, diabetes, and hypertension had approximately multiplicative effects on relative risk. CONCLUSIONS--This study indicates that serum cholesterol was an independent risk factor for acute myocardial infarction. This association was linear, with no threshold level. Moreover, there was a multiplicative effect between cholesterol and other major risk factors on the relative risk of acute myocardial infarction. PMID:8011413

  16. An extended diffraction-enhanced imaging method for implementing multiple-image radiography

    2007-04-01

    Diffraction-enhanced imaging (DEI) is an analyser-based x-ray imaging method that produces separate images depicting the projected x-ray absorption and refractive properties of an object. Because the imaging model of DEI does not account for ultra-small-angle x-ray scattering (USAXS), the images produced in DEI can contain artefacts and inaccuracies in medical imaging applications. In this work, we investigate an extended DEI method for concurrent reconstruction of three images that depict an object's projected x-ray absorption, refraction and USAXS properties. The extended DEI method can be viewed as an implementation of the recently proposed multiple-image radiography paradigm. Validation studies are conducted by use of computer-simulated and synchrotron measurement data.

    Conventional mammography can not distinguish between transmitted, scattered, or refracted x-rays, thus requiring breast compression to decrease tissue depth and separate overlapping structures. Diffraction-enhanced imaging (DEI) uses monochromatic x-rays and perfect crystal diffraction to generate images with contrast based on absorption, refraction, or scatter. Because DEI possesses inherently superior contrast mechanisms, the current study assesses the effect of breast compression on lesion characteristic visibility with DEI imaging of breast specimens. Eleven breast tissue specimens, containing a total of 21 regions of interest, were imaged by DEI uncompressed, half-compressed, or fully compressed. A fully compressed DEI image was displayed on a soft-copy mammography review workstation, next to a DEI image acquired with reduced compression, maintaining all other imaging parameters. Five breast imaging radiologists scored image quality metrics considering known lesion pathology, ranking their findings on a 7-point Likert scale. When fully compressed DEI images were compared to those acquired with approximately a 25% difference in tissue thickness, there was no difference in scoring of lesion feature visibility. For fully compressed DEI images compared to those acquired with approximately a 50% difference in tissue thickness, across the five readers, there was a difference in scoring of lesion feature visibility. The scores for this difference in tissue thickness were significantly different at one rocking curve position and for benign lesion characterizations. These results should be verified in a larger study because when evaluating the radiologist scores overall, we detected a significant difference between the scores reported by the five radiologists. Reducing the need for breast compression might increase patient comfort during mammography. Our results suggest that DEI may allow a reduction in compression without substantially compromising clinical image

    X-ray diffraction enhanced imaging (DEI) is a phase contrast technique that generates excellent contrast of biological soft tissues compared to conventional absorption radiography. We explore the application of DEI in the diagnosis of hepatic fibrosis. The produced refraction contrast images of fibrous rat liver samples show clearly abnormal liver architectures. Moreover, by comparing to histological pictures, different stages of fibrosis are discriminated, and the corresponding morphological features are analyzed. Besides, quantitative analyses of texture features are presented. The results reported herein show that DEI can be a potential noninvasive technique to diagnose and stage hepatic fibrosis.

    This paper describes the design, construction, and performance of a new DEI system using a commercially available tungsten anode x-ray tube and includes the first high-quality low-dose diffraction-enhanced images of full-thickness human tissue specimens. Diffraction-enhanced imaging (DEI) is a new x-ray imaging modality that differs from conventional radiography in its use of three physical mechanisms to generate contrast. DEI is able to generate contrast from x-ray absorption, refraction, and ultra-small-angle scatter rejection (extinction) to produce high-contrast images with a much lower radiation dose compared to conventional radiography.

    In this paper, we propose a novel multi diffraction enhanced imaging (MDEI) technique to improve contrast resolution owning to the sharp rise of the reflectivity curve and high contrast-to-noise ratio (CNR). MDEI is derived from the diffraction enhanced imaging (DEI) technique. Here, DEI and MDEI phase contrast tomograms are compared. The results show that MDEI offers higher contrast resolution, while DEI has higher spatial resolution. This study provided indications for developments and applications of X-ray crystal analyzer-based imaging to obtain a higher contrast resolution.

    Recently, management of limited stage diffuse large cell lymphoma (DLCL) is trending toward a low intensity chemotherapy approach. Since 1993 we have used a brief weekly (6 weeks) chemotherapy scheme (Doxorubicin, Cyclophosphamide, Bleomycin, Vincristine, and Prednisone = ACOP-B) followed by involved field radiotherapy in 207 consecutive patients with well defined localized DLCL without age limit (median 57 years, range 18-85). Treatment was completed as designed in 183 of 207 patients (88%). One hundred and ninety-nine patients (96%) achieved complete remission. At a median follow-up of 66 months 170 patients are alive (82%), 168 of them free of disease. Twenty-nine patients experienced relapse after achieving a complete remission. Kaplan-Meier, risk of relapse was 24% after 13 years. Thirty (14.5%) patients have died, 14 (6.8%) due to lymphoma progression, one due to regimen toxicity and 15 (7.2%) from other causes while remaining in complete remission. The probability of overall survival and event free survival at 13 years was 78% (95% CI 70-87%) and 63% (95% CI 50-75), respectively. Crude rate of secondary malignancy was 5.26 /1000 person-years. The ACOP-B regimen plus involved field radiotherapy is well tolerated both short and long term and is an effective chemotherapy scheme for very well defined limited stage aggressive non-Hodgkin lymphomas in all age categories.

    Diffraction-enhanced imaging (DEI) is a phase-contrast X-ray imaging technique suitable for visualizing light-element materials. The method also enables observations of sample-containing regions with large density gradients. In this study a cryogenic imaging technique was developed for DEI-enabled measurements at low temperature from 193 K up to room temperature with a deviation of 1 K. Structure-II air hydrate and structure-I carbon dioxide (CO(2)) hydrate were examined to assess the performance of this cryogenic DEI technique. It was shown that this DEI technique could image gas hydrate coexisting with ice and gas bubbles with a density resolution of about 0.01 g cm(-3) and a wide dynamic density range of about 1.60 g cm(-3). In addition, this method may be a way to make temperature-dependent measurements of physical properties such as density. PMID:23093767

  8. Digitally Enhanced Heterodyne Interferometry

    2010-01-01

    Spurious interference limits the performance of many interferometric measurements. Digitally enhanced interferometry (DEI) improves measurement sensitivity by augmenting conventional heterodyne interferometry with pseudo-random noise (PRN) code phase modulation. DEI effectively changes the measurement problem from one of hardware (optics, electronics), which may deteriorate over time, to one of software (modulation, digital signal processing), which does not. DEI isolates interferometric signals based on their delay. Interferometric signals are effectively time-tagged by phase-modulating the laser source with a PRN code. DEI improves measurement sensitivity by exploiting the autocorrelation properties of the PRN to isolate only the signal of interest and reject spurious interference. The properties of the PRN code determine the degree of isolation.

    The primary response of BALB/c mice to sheep red blood cells was used to study comparatively the time-dependent effects of a 5-day course of treatment with equivalent doses (0.8 mg/kg of body weight every day) of the cytotoxic agent diethyleneiminebenzoquinone (DEiBq) and its polymer complex with polyvinylpyrrolidone (DEiBqPVP). The experimental results show that in contrast to treatment with DEiBq, the ability of treated mice to establish a specific immune response was not markedly impaired during the treatment with DEiBqPVP. The possible significance of these results is considered with reference to the use of the synthetic polymer PVP as a carrier of cytotoxic groups in experimental cancer chemotherapy. PMID:556384

    Background/Aim Diffraction enhanced imaging (DEI) is a synchrotron radiation X-ray phase-contrast imaging technique that can better reveal the microstructure of biological soft tissues than conventional X-rays. The aim of this study is to investigate the angio-architectural changes of the liver during fibrosis, cirrhosis and its subsequent regression by applying synchrotron radiation based DEI. Methods DEI experiments were performed at the 4W1A station of Beijing Synchrotron Radiation Facility. Twenty-four Sprague-Dawley rats were induced with liver fibrosis by carbon tetrachloride (CCl4) for up to 10 weeks, after which spontaneous regression started and continued until week 30. Quantitative analysis of the DEI images yielded the mean vascular density and intercapillary distance, which was then re-confirmed by immunohistochemical analysis of CD34. Results Based on the DEI results, the mean vascular density was 1.4-fold higher in fibrotic rats (at week 6) and 2-fold higher in cirrhotic rats (at week 10) compared with the control (p<0.05). Accordingly, the intercapillary distance decreased to 563.89±243.35 µm in fibrotic rats and 392.90±92.68 µm in cirrhotic rats compared with 673.85±214.16µm in the control (p<0.05). During fibrosis regression at week 30, vascular density was 0.7-fold lower and intercapillary distance increased to 548.60±210.94 µm as compared with cirrhotic rats (p<0.05).In parallel to the DEI results, immunohistochemical analysis of CD34 showed similar changes. Conclusion Synchrotron-based DEI can conduct radiological as well as pathological analysis. Our results are consistent with previous reports indicating that angiogenesis is directly proportional to fibrosis progression. Furthermore, by clarifying the vascular characteristics of liver diseases, DEI reveals that cirrhosis cannot fully reverse during fibrosis regression. PMID:24504507

    Bonneville Power Administration (BPA) and Puget Sound Power & Light Company (Puget Power) propose to upgrade the existing high-voltage transmission system in the Whatcom and Skagit counties area between the towns of Custer and Sedro Woolley, including some areas within the City of Bellingham, starting in 1995. A Draft Environmental Impact Statement (DEIS) for the project was issued in November 1993, followed by a 45-day public comment period. Public response to the DEIS included the identification of several new transmission route alternatives in the Lake Whatcom area. BPA issued a Supplemental DEIS in April 1995 to provide a second public review-and-comment period. Rebuilding an existing 230-kV line to a double-circuit 230-kV transmission line was identified in the Supplemental DEIS as the Proposed Action. The Supplemental DEIS also examined in detail a North Shore Road alternative which was proposed by some members of the public. Public comments on the EIS were listed and responded to in the Supplemental DEIS. In May 1995, a second set of open houses and public meetings was held to review the Supplemental DEIS. Electromagnetic field (EMF) effects raised as an issue in the DEIS continued to be an issue of public concern in the meetings. The EIS has identified impacts that would generally be classified as low to moderate and localized. Effects on soils and water resources in sensitive areas (e.g., near Lake Whatcom) would be low to moderate; there would be little change in magnetic fields; noise levels would remain at existing levels; and land use and property value impacts would be minimal. Threatened and endangered species would not be adversely affected, and all proposed actions in wetlands would be covered by a Corps of Engineers Nationwide Permit. Visual and socioeconomic would be low to moderate. There would be no effect on cultural resources.

    Objective: To demonstrate the ability of a novel radiographic technique, Diffraction Enhanced Radiographic Imaging (DEI), to render high contrast images of canine knee joints for identification of cartilage lesions in situ. Methods: DEI was carried out at the X-15A beamline at Brookhaven National Laboratory on intact canine knee joints with varying levels of cartilage damage. Two independent observers graded the DE images for lesions and these grades were correlated to the gross morphological grade. Results: The correlation of gross visual grades with DEI grades for the 18 canine knee joints as determined by observer 1 (r2=0.8856, P=0.001) and observer 2 (r2=0.8818, P=0.001) was high. The overall weighted ? value for inter-observer agreement was 0.93, thus considered high agreement. Conclusion: The present study is the first study for the efficacy of DEI for cartilage lesions in an animal joint, from very early signs through erosion down to subchondral bone, representing the spectrum of cartilage changes occurring in human osteoarthritis (OA). Here we show that DEI allows the visualization of cartilage lesions in intact canine knee joints with good accuracy. Hence, DEI may be applicable for following joint degeneration in animal models of OA.

    Images of vertebrates (zebrafish and zebrafish eye) have been obtained by using an X-ray phase-contrast imaging technique, namely, synchrotron-based diffraction-enhanced imaging (SY-DEI) (or analyzer based imaging) and synchrotron-based diffraction imaging in tomography mode (SY-DEI-CT). Due to the limitations of the conventional radiographic imaging in visualizing the internal complex feature of the sample, we utilized the upgraded SY-DEI and SY-DEI-CT systems to acquire the images at 20, 30 and 40 keV, to observe the enhanced contrast. SY-DEI and SY-DEI-CT techniques exploits the refraction properties, and have great potential in studies of soft biological tissues, in particular for low (Z) elements, such as, C, H, O and N, which constitutes the soft tissue. Recently, these techniques are characterized by its extraordinary image quality, with improved contrast, by imaging invertebrates. We have chosen the vertebrate sample of zebrafish (Danio rerio), a model organism widely used in developmental biology and oncology. For biological imaging, these techniques are most sensitive to enhance the contrast. For the present study, images of the sample, in planar and tomography modes offer more clarity on the contrast enhancement of anatomical features of the eye, especially the nerve bundle, swim bladder, grills and some internal organs in gut with more visibility.

    The authors examined the changes, which occurred in the weight of lymphoid organs (thymus, spleen, and lymph nodes) and titre of serum hemagglutinines against sheep erythrocytes in mice BAIB/c under the influence of treatment with diethyleniminbenzochinon and some of its complexes with polyvinylpirolidon (PVP). The ratio of the substances composing the complexes (in mg per 1000 mg of complex) was as followed: DEiBx- PVP complex NoI-340:660; DEiBx-PVP complex No2-200:800; DEiBx-PVP-Uracyl complex No3-250:500:250. There was a sharp reduction of the weight of lymphoid organs in mice, treated with DEiBx, singly or in the form of complexes NoI and No2 in comparison with the control nontreated mice or treated with complex No3. This effect was more manifested after treatment with DEiBx during the same regimen (0.8 mg/kg of body weight daily for 5 days). The ability of the treated animals to react to immunization with sheep erythrocytes practicaly was not impaired during the treatment with complexes No2 and No3 or the damage was slight (complex NoI) in contrast to the treatment with DEiBx.

    2014-03-01

    Purpose: The purpose of this study is to determine if diffraction enhanced imaging (DEI) can quantify anisotropy in bone microarchitecture. Background: Osteoporosis is characterized by low bone mass and microarchitectural deterioration of bone. A noninvasive tool for measuring the degree of anisotropy (DA) in bone microarchitecture will help clinicians better assess fracture risk in osteoporotic patients. DEI detects small angular deflections in an x-ray beam, and is only sensitive to angular changes in one plane. If the beam is refracted by multiple anisotropic microstructures (e.g. osteocyte lacunae and pores) in bone, the angular spreading can be measured with DEI and differences in the amount of spreading for different bone orientations is indicative of the DA in bone microarchitecture. Method: An x-ray-tube based DEI system was used to collect an array of DEI reflectivity profiles measured through bovine cortical bone samples with the bones oriented with the bone axis in the plane perpendicular to the propagation of the x-ray beam. Micro-CT images of the bones were obtained using a Scanco uCT40 ex vivo scanner, and the DA of the pore structure was quantified using BoneJ. Results: The maximum and minimum measured reflectivity profile widths through bone varied by a factor of two; this suggests that the microarchitecture is preferentially aligned with the bone axis in a 2-to-1 ratio. The DA for the cortical pores was 0.6, which agrees with DEI's anisotropy measure. Conclusions: The preliminary findings of this study suggest that DEI is sensitive to anisotropy in bone microarchitecture.

    Our understanding of early development in Alzheimer's disease (AD) is clouded by the scale at which the disease progresses; amyloid beta (A{beta}) plaques, a hallmark feature of AD, are small ({approx} 50 {micro}m) and low contrast in diagnostic clinical imaging techniques. Diffraction enhanced imaging (DEI), a phase contrast x-ray imaging technique, has greater soft tissue contrast than conventional radiography and generates higher resolution images than magnetic resonance microimaging. Thus, in this proof of principle study, DEI in micro-CT mode was performed on the brains of AD-model mice to determine if DEI can visualize A{beta} plaques. Results revealed small nodules in the cortex and hippocampus of the brain. Histology confirmed that the features seen in the DEI images of the brain were A{beta} plaques. Several anatomical structures, including hippocampal subregions and white matter tracks, were also observed. Thus, DEI has strong promise in early diagnosis of AD, as well as general studies of the mouse brain.

    The aim of this study was to introduce high-resolution computed tomography (CT) of breast tumours using the diffraction-enhanced x-ray imaging (DEI) technique and to compare results with radiological and histo-pathological examinations. X-ray CT images of tumour-bearing breast tissue samples were acquired by monochromatic synchrotron radiation (SR). Due to the narrow beam and a large sample-to-detector distance scattering is rejected in the absorption contrast images (SR-CT). Large contrast enhancement is achieved by the use of the DEI-CT method, where the effects of refraction and scatter rejection are analysed by crystal optics. Clinical mammograms and CT images were recorded as reference material for a radiological examination. Three malignant and benign samples were studied in detail. Their radiographs were compared with optical images of stained histological sections. The DEI-CT images map accurately the morphology of the samples, including collagen strands and micro-calcifications of dimensions less than 0.1 mm. Histo-pathological examination and reading of the radiographs were done independently, and the conclusions were in general agreement. High-resolution DEI-CT images show strong contrast and permit visualization of details invisible in clinical radiographs. The radiation dose may be reduced by an order of magnitude without compromising image quality, which would make possible clinical in vivo DEI-CT with future compact SR sources. PMID:17404464

    Diffraction enhanced imaging (DEI) uses monochromatic x-rays coupled to an analyzer crystal to extract information about the refraction of x-rays within the object. Studies of excised biological tissues show that DEI has significant contrast-to-noise ratio (CNR) advantages for soft tissue when compared to standard radiography. DEI differs from conventional CT in that its refraction contrast depends on x-ray energy as 1/E, thus the energy and dose considerations for conventional CT will be inappropriate. The goal of this study was to assess the optimal energy for in vivo CT imaging of a mouse head to obtain the largest soft tissue refraction CNR. Through a theoretical model, optimum refraction CNR for mouse brain imaging was found to be about 20 keV. The findings were tested experimentally using the DEI system at the X15A beamline of the National Synchrotron Light Source. Using the parameters for optimized refraction CNR (20 keV, silicon [333] reflection), large image artifacts were caused by DEI's scatter-rejection properties. By increasing the x-ray energy and using a lower order diffraction, silicon [111], soft tissue features within the brain, including the hippocampus, could be resolved.

    A typical pepper-forest boundary was selected in the arid valley of Minjiang River upper reaches, and the moisture content in 0-15 cm soil layer was determined by time-domain reflectometry (TDR) during drought, after rain, and different seasons. Moving split-window techniques (MSWT) was employed to detect the depth of edge influence (DEI) on soil moisture and its dynamic variation with time. The results showed that the changes of squared Euclidean distance (SED) curve on the graph tended to become stable when the window width reached 8 - 12, and DEI could be detected. The seasonal variation of soil moisture could be divided into three periods, i.e., rising period (January to April), peak period (May to October), and lessen period (November to December). DEI was smaller during drought, and increased after rain. The DEI on soil moisture ranged from 6 m in pepper field to 2 m in forest during drought and from 12 m in pepper field to 2 m in forest after rain, but ranged from 10 m in pepper field to 2 m in forest field within a year. DEI was different in different seasons, and was dynamic. Under such condition of soil moisture, the forest restoration from pepper land and the seedling planting were not ecologically reasonable. Reducing human disturbance and revegetating with natural shrubs and meadows could be more effective for vegetation conservation in the arid valley of Minjiang River upper reaches. PMID:17269317

    The objective of this project was to develop and test a new technology for imaging growing joints by means of diffraction-enhanced imaging (DEI) combined with CT and using a synchrotron radiation source. DEI–CT images of an explanted 4-wk-old piglet stifle joint were acquired by using a 40-keV beam. The series of scanned slices was later ‘stitched’ together, forming a 3D dataset. High-resolution DEI-CT images demonstrated fine detail within all joint structures and tissues. Striking detail of vasculature traversing between bone and cartilage, a characteristic of growing but not mature joints, was demonstrated. This report documents for the first time that DEI combined with CT and a synchrotron radiation source can generate more detailed images of intact, growing joints than can currently available conventional imaging modalities.

    The hypothesis was tested that fish fed to satiation with iso-energetic diets differing in macronutrient composition will have different digestible energy intakes (DEI) but similar total heat production. Four iso-energetic diets (2×2 factorial design) were formulated having a contrast in i) the ratio of protein to energy (P/E): high (HP/E) vs. low (LP/E) and ii) the type of non-protein energy (NPE) source: fat vs. carbohydrate which were iso-energetically exchanged. Triplicate groups (35 fish/tank) of rainbow trout were hand-fed each diet twice daily to satiation for 6 weeks under non-limiting water oxygen conditions. Feed intake (FI), DEI (kJ kg−0.8 d−1) and growth (g kg−0.8 d−1) of trout were affected by the interaction between P/E ratio and NPE source of the diet (P<0.05). Regardless of dietary P/E ratio, the inclusion of carbohydrate compared to fat as main NPE source reduced DEI and growth of trout by ∼20%. The diet-induced differences in FI and DEI show that trout did not compensate for the dietary differences in digestible energy or digestible protein contents. Further, changes in body fat store and plasma glucose did not seem to exert a homeostatic feedback control on DEI. Independent of the diet composition, heat production of trout did not differ (P>0.05). Our data suggest that the control of DEI in trout might be a function of heat production, which in turn might reflect a physiological limit related with oxidative metabolism. PMID:22496852

    Crystalline lenses are transparent biological materials where the organization of the lens fibers can also be affected by changes at molecular level, and therefore the structure and morphology of the tissue can be correlated to the loss of transparency of the lens. In this work, internal structure of mammal lenses regarding the long-range ordering of the fibers are investigated by diffraction enhanced X-ray imaging (DEI) radiography. Moreover, DEI and absorption X-ray synchrotron radiographs for healthy and cataractous crystalline lenses are compared. Significant differences in healthy and cataractous crystalline lenses are observed.

    1992-01-01

    A complete set of fan blades for the National Transonic Facility (NTF) at the NASA Langley Research Center was recently fabricated by Dynamic Engineering Inc. (DEI). These blades were the third complete set of blades fabricated by the NTF. The first set of blades was fabricated by NASA and installed in the tunnel in December 1981. This original set was destroyed in a mishap in January 1989. The second set of blades is currently in use in the NTF. The third set of blades recently fabricated by DEI is a spare set. In order to ensure that the blades met the requirements, DEI performed a series of tests on each of the completed blades. In addition, a model survey was conducted on each blade to define the dynamic characteristics. Discussed here are the blade tests conducted by DEI and the test results. The test set-ups and procedures are discussed in detail. The results obtained for each of the 27 blades are documented and comparisons are made between this set of blades and similar data for two previous sets of NTF fan blades.

    Rocha, H. S.; Lopes, R. T.; Valiante, P. M.; Tirao, G.; Mazzaro, I.; Hönnicke, M. G.; Cusatis, C.; Giles, C.

    Diffraction-enhanced images (DEI) have been obtained using two silicon crystals. A first channel-cut silicon crystal using the Si(3 3 3) reflection is employed to reduce the divergence of the pre-monochromated Si(1 1 1) beam of the light line to 60 microradian (12 arcsec). A second channel-cut Si(3 3 3) crystal was used as a Bragg analyzer to obtain bright and dark field images by changing its angular position. This technique is ideally suited for soft-tissue imaging or objects with the same absorption coefficient interfaces. DEI was developed at the XRD-2 beamline at the Brazilian Synchrotron (LNLS) in Campinas—Brazil. Feasibility tests on acquired images, which allow the diagnosis of thyroid nodular goiter, were performed. This disease is ordinary. The tissue developed on the cervical area causes compression of the nearby structures and undesirable aesthetic deformities with worldwide distribution. DEI of the tissues were taken to observe their morphology and to compare with the microscopic analysis (histopathological). This technique allows cutting sections a hundred times thicker than conventional histological techniques allowing a complete vision of the disease morphology. DEI show details not clearly seen with conventional techniques.

    A description of the rocking curve in diffraction enhanced imaging (DEI) is presented in terms of the angular signal response function and a simple multi-information retrieval algorithm based on the cosine function fitting. A comprehensive analysis of noise properties of DEI is also given considering the noise transfer characteristic of the X-ray source. The validation has been performed with synchrotron radiation experimental data and Monte Carlo simulations based on the Geant4 toolkit combined with the refractive process of X-rays, which show good agreement with each other. Moreover, results indicate that the signal-to-noise ratios of the refraction and scattering images are about one order of magnitude better than that of the absorption image at the edges of low-Z samples. The noise penalty is drastically reduced with the increasing photon flux and visibility. Finally, this work demonstrates that the analytical method can build an interesting connection between DEI and GDPCI (grating-based differential phase contrast imaging) and is widely suitable for a variety of measurement noise in the angular signal response imaging prototype. The analysis significantly contributes to the understanding of noise characteristics of DEI images and may allow improvements to the signal-to-noise ratio in biomedical and material science imaging.

  16. Improvement and error analysis of quantitative information extraction in diffraction-enhanced imaging

    NASA Astrophysics Data System (ADS)

    Yang, Hao; Xuan, Rui-Jiao; Hu, Chun-Hong; Duan, Jing-Hao

    2014-04-01

    Diffraction-enhanced imaging (DEI) is a powerful phase-sensitive technique that provides higher spatial resolution and supercontrast of weakly absorbing objects than conventional radiography. It derives contrast from the X-ray absorption, refraction, and ultra-small-angle X-ray scattering (USAXS) properties of an object. The separation of different-contrast contributions from images is an important issue for the potential application of DEI. In this paper, an improved DEI (IDEI) method is proposed based on the Gaussian curve fitting of the rocking curve (RC). Utilizing only three input images, the IDEI method can accurately separate the absorption, refraction, and USAXS contrasts produced by the object. The IDEI method can therefore be viewed as an improvement to the extended DEI (EDEI) method. In contrast, the IDEI method can circumvent the limitations of the EDEI method well since it does not impose a Taylor approximation on the RC. Additionally, analysis of the IDEI model errors is performed to further investigate the factors that lead to the image artifacts, and finally validation studies are conducted using computer simulation and synchrotron experimental data.

  12. Meet the Maximally Exposed Member of the Public: The Service Station Attendant for Spent Nuclear Fuel Going to Yucca Mountain

    SciTech Connect

    2002-02-28

    According to the 1999 Draft Environmental Impact Statement (DEIS) for the proposed Yucca Mountain repository site, members of the public along transportation routes by which spent nuclear fuel (SNF) and high-level radioactive waste (HLW) is shipped will receive annual radiation doses less than 100 mrem/yr, the international (ICRP) and national (Department of Energy, Nuclear Regulatory Commission) radiation limit for members of the public. For the ''Mostly Truck'' national transportation scenario, the DEIS specifically concludes that the maximally exposed member of the public, a service station attendant along the primary shipping route will receive no more than 100 mrem/yr, or 2.4 rem over 24 years. Based on the assumptions in the DEIS scenarios, however, it is highly likely that service station attendants along shipping routes will be called upon to fuel and service the rigs carrying SNF and HLW to Yucca Mountain. After reevaluating the DEIS, and making realistic alternative assumptions where necessary, the authors conclude that these attendants are likely to receive substantially more than 100 mrem/yr external dose, and perhaps several times that dose (up to 500 mrem/yr), unless mitigating measures are adopted. This is particularly true in Western states where refueling opportunities are limited, and the distances between fuel sources in rural areas may be up to 100 miles.

    1992-10-01

    Washington Water Power (WWP) proposes to construct and operate an electric transmission line that would connect with the electrical system of the British Columbia Hydro and Power Authority (B.C. Hydro). The project would be composed of a double-circuit, 230-kilovolt (kV) transmission line from WWP`s existing Beacon Substation located northeast of Spokane, Washington to the international border located northwest of Metaline Falls, Washington. The original Presidential permit application and associated proposed route presented in the draft environmental impact statement (DEIS) have been modified to terminate at the Beacon Substation, instead of WWP`s initially proposed termination point at the planned Marshall Substation located southwest of Spokane. A supplemental draft EIS was prepared and submitted for review to not only examine the new proposed 5.6 miles of route, but to also compare the new Proposed Route to the other alternatives previously analyzed in the DEIS. This final EIS (FEIS) assesses the environmental effects of the proposed transmission line through construction, operation, maintenance, and abandonment activities and addresses the impacts associated with the Proposed Action, Eastern Alternative, Western Alternative, Northern Crossover Alternative, Southern Crossover Alternative, and No Action Alternative. The FEIS also contains the comments received and the responses to these comments submitted on the DEIS and Supplemental DEIS.

    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

    2016-08-01

    Riassunto. Lo scopo di questo studio è quello di valutare i costi dei farmaci (con particolare riferimento alle terapie con farmaci biologici) utilizzati nella terapia di conversione in una popolazione non selezionata di pazienti affetti da carcinoma del colon-retto in stadio avanzato, al fine di ottenere una resezione epatica R0. In questa rassegna sono stati selezionati i report completi e gli aggiornamenti di tutti gli studi clinici randomizzati (di fase II e fase III) che confrontassero almeno 2 regimi di terapia con farmaci biologici in prima linea in pazienti affetti da carcinoma del colon-retto in stadio avanzato di malattia. I costi dei farmaci sono stati ricavati dalla nostra Farmacia Ospedaliera e sono espressi in euro (€). Il nostro studio inizia con la valutazione di 683 abstract. 48 tria sono stati considerati adeguati per una successiva analisi. Una valutazione più approfondita ha portato all'esclusione di 37 trial, lasciando alla valutazione finale 11 studi clinici randomizzati (3 trial di fase II, per un totale di 522 pazienti, e 8 studi di fase III, per un totale di 7191 pazienti). I costi dei farmaci utilizzati nella terapia di conversione aumentano con la sostituzione del 5-fluorouracile con la capecitabina e, in misura maggiore, con l'introduzione degli agenti biologici. In questo lavoro sono presentati due punti chiave. Primo, i costi degli agenti farmacologici utilizzati nei regimi di prima linea a base di agenti biologici più comunemente utilizzati nel trattamento del carcinoma del colon-retto in stadio avanzato sono molto variabili. Secondo, i dati di efficacia dei regimi pubblicati, in termini di tassi di resezione, dipendono dalla selezione dei pazienti, dalle caratteristiche del tumore e dal tipo di schema di terapia.

  18. Wave front and phase correction for double-ended gauge block interferometry

    NASA Astrophysics Data System (ADS)

    Lassila, A.; Byman, V.

    2015-10-01

    Double-ended interferometry has several benefits over single-ended gauge block interferometry: there is no need for wringing, which wears surfaces and requires expertise, and there is improved repeatability, since there is no variation due to inconsistent wringing conditions or form errors of the gauge block surfaces. Some disadvantages of double-ended interferometry are that absolute phase change correction is needed for the gauge block and its uncertainty has a double effect on total uncertainty. In addition, elimination of the wavefront error is more complicated than with single-ended interferometry. A simple optical modification that enables double-ended interferometer (DEI) measurements with the MIKES interferometer for long gauge blocks is presented. This modification is applicable to almost any single-ended interferometer (SEI). A procedure for evaluating the wave front correction for different parts of the interferogram of DEI is explained, and a modification and software with capability for nine-point phase stepping is presented. Three independent methods for evaluation of the phase correction were studied. One of them uses integrating sphere for the surface roughness correction and literature values for the phase change due to complex refractive index of material correction. The second evaluates the phase correction from the difference between DEI and SEI results obtained with a quartz platen. The third uses differences—from separate measurements—between the results obtained with quartz or steel auxiliary platens. Only a few gauge blocks per set need testing to obtain phase correction. SEI and DEI results with different phase correction determination methods are presented and evaluated. The uncertainty estimate for gauge block calibration with DEI gives a similar standard uncertainty to that with the best SEIs, u=\\sqrt{{{≤ft(10.0~ \\text{nm}\\right)}2}+{{≤ft(118× {{10}-9}L\\right)}2}} .

    This study investigates the capabilities of low tube voltage computed tomography (CT) and dual-energy CT (DECT) for predicting successful shock wave lithotripsy (SWL) of urinary stones in vitro. A total of 33 urinary calculi (six different chemical compositions; mean size 6 ± 3 mm) were scanned using a dual-source CT machine with single- (120 kVp) and dual-energy settings (80/150, 100/150 Sn kVp) resulting in six different datasets. The attenuation (Hounsfield Units) of calculi was measured on single-energy CT images and the dual-energy indices (DEIs) were calculated from DECT acquisitions. Calculi underwent SWL and the number of shock waves for successful disintegration was recorded. The prediction of required shock waves regarding stone attenuation/DEI was calculated using regression analysis (adjusted for stone size and composition) and the correlation between CT attenuation/DEI and the number of shock waves was assessed for all datasets. The median number of shock waves for successful stone disintegration was 72 (interquartile range 30-361). CT attenuation/DEI of stones was a significant, independent predictor (P < 0.01) for the number of required shock waves with the best prediction at 80 kVp (β estimate 0.576) (P < 0.05). Correlation coefficients between attenuation/DEI and the number of required shock waves ranged between ρ = 0.31 and 0.68 showing the best correlation at 80 kVp (P < 0.001). The attenuation of urinary stones at low tube voltage CT is the best predictor for successful stone disintegration, being independent of stone composition and size. DECT shows no added value for predicting the success of SWL. PMID:26391614

    A previous "Retrospectroscope" note, published early in 2014, dealt with spirometry: it described many apparatuses used to measure the volume of inhaled and exhaled air that results from breathing [1]. Such machines, when adequately modified, are also able to measure the rate at which work is produced (specifically by an animal or a human being). Metabolism in that sense is the term used by physiologists and physicians, a word that in Greek, metabolismos, means "change" or "overthrow," in the sense of breaking down material, as in burning some stuff.

    An attempt has been made, for the first time, to extend the capabilities of diffraction enhanced imaging (DEI) using low concentrations of a contrast agent. A phantom has been constructed to accommodate a systematic series of diluted bromine deoxyuridase (BrDU) samples in liquid form. This was imaged using a conventional DEI arrangement and at a range of energies traversing the Br K-edge. The images were analyzed to provide a quantitative measure of contrast as a function of X-ray energy and (BrDU) concentration. The results indicate that the particular experimental arrangement was not optimized to exploit the potential of this contrast enhancement and several suggestions are discussed to improve this further.

    Utilizzando la grande quantita' di dati sui blazar disponibile ad oggi, e' possibile costruire una distribuzione spettrale di energia (SED) media per ciascuna classe di oggetti. Basandosi su un modello SSC, e' inoltre possibile stimare il comportamento di questi oggetti nella banda di energia dei raggi gamma partendo dalle informazioni ottenute da osservazioni in altre bande di energia quali il radio e l'X. Utilizzando le simulazioni sara` possibile prevedere un eventuale cambio di popolazione dominante ad alte energie(oltre 1GeV) rispetto a quanto avviene in banda radio dove domina la popolazione dei FSRQ rispetto ai BL Lac e cercare un'eventuale conferma dagli esperimenti AGILE e GLAST.

    Structural, thermobarometric, geochronological, and thermochronological evidence suggests that the D'Entrecasteaux Islands (DEI) and the Dayman-Suckling massif (DSM), in southeastern Papua New Guinea, are metamorphic core complexes, which have been exhumed from depths as great as 90 km over the past 2- -8 Ma, possibly because of microplate rotation. The dome-shaped DEI and DSM reach elevations of ~2500 m and ~3500 m, respectively, however little is known about their kinematic histories since their emergence above sea level in the Plio-Pleistocene. Detachment faults are commonly corrugated or dip- slope surfaces occurring in various states of dissection. The question of whether faults bounding the DEI domes are active today remains debated, yet has implications for what mechanisms have exhumed the core complexes as well as where and how active rifting in the Woodlark rift is accommodated. In order to provide a regional overview and direct future tectonic geomorphic studies, we conducted a stream profile analysis of the DEI and DSM using a 3-arc-second Shuttle Radar Topography Mission digital elevation model. Footwall stream profiles in the study area are characterized by large knickpoints across which stream gradients steepen downstream by a factor of 2. These knickpoints are not typically associated with mapped lithologic contacts or faults and occur in all lower plate lithologies. Therefore, we interpret the knickpoints as transients formed as the result of a Quaternary region-wide increase in rock uplift rate or a decrease in stream erodibility. Model profiles extrapolated from relict reaches above knickpoints project to former base levels 40- -1600 m above sea level, indicating similar amounts of incision and rock uplift. Although the timing of knickpoint initiation is not tightly constrained and may vary throughout the region, estimates of profile uplift measured this way correlate linearly with normalized stream steepness index (ksn) below knickpoints

    Diffraction enhanced imaging (DEI) has been widely applied in many fields, especially when imaging low-Z samples or when the difference in the attenuation coefficient between different regions in the sample is too small to be detected. Recent developments of this technique have presented a need for a new software package for data analysis. Here, the Diffraction Enhanced Image Reconstructor (DEIReconstructor), developed in Matlab, is presented. DEIReconstructor has a user-friendly graphical user interface and runs under any of the 32-bit or 64-bit Microsoft Windows operating systems including XP and Win7. Many of its features are integrated to support imaging preprocessing, extract absorption, refractive and scattering information of diffraction enhanced imaging and allow for parallel-beam tomography reconstruction for DEI-CT. Furthermore, many other useful functions are also implemented in order to simplify the data analysis and the presentation of results. The compiled software package is freely available.

    Articular cartilage of synovial joints is not visible with conventional X-ray imaging. Hence, the gradual degeneration and destruction of articular cartilage, which is characteristic of degenerative joint diseases, is only detected at a late stage when the cartilage is lost and the joint space that it once occupied narrows. The development of an X-ray imaging technique that could detect both the degenerative cartilage and bone features of joint diseases is of special interest. Here we show, for the first time, that a high-contrast imaging technique, diffraction-enhanced X-ray imaging (DEI), allows the visualization of articular cartilage of both disarticulated and articulated rabbit knee joints. Furthermore, a single cartilage lesion can be visualized within an intact joint. The results suggest that DEI has the potential to be of use in the study of cartilage degeneration. PMID:12704696

    Non-calcified tissues, including tendons, ligaments, adipose tissue and cartilage, are not visible, for any practical purposes, with conventional X-ray imaging. Therefore, any pathological changes in these tissues generally necessitate detection through magnetic resonance imaging or ultrasound technology. Until recently the development of an X-ray imaging technique that could detect both bone and soft tissues seemed unrealistic. However, the introduction of diffraction enhanced X-ray imaging (DEI) which is capable of rendering images with absorption, refraction and scatter rejection qualities has allowed detection of specific soft tissues based on small differences in tissue densities. Here we show for the first time that DEI allows high contrast imaging of soft tissues, including ligaments, tendons and adipose tissue, of the human foot and ankle. PMID:15153594

    Under osmotic stress conditions such as drought and high salinity, the plant hormone abscisic acid (ABA) plays important roles in stress-responsive gene expression mainly through three bZIP transcription factors, AREB1/ABF2, AREB2/ABF4 and ABF3, which are activated by SNF1-related kinase 2s (SnRK2s) such as SRK2D/SnRK2.2, SRK2E/SnRK2.6 and SRK2I/SnRK2.3 (SRK2D/E/I). However, since the three AREB/ABFs are crucial, but not exclusive, for the SnRK2-mediated gene expression, transcriptional pathways governed by SRK2D/E/I are not fully understood. Here, we show that a bZIP transcription factor, ABF1, is a functional homolog of AREB1, AREB2 and ABF3 in ABA-dependent gene expression in Arabidopsis. Despite lower expression levels of ABF1 than those of the three AREB/ABFs, the areb1 areb2 abf3 abf1 mutant plants displayed increased sensitivity to drought and decreased sensitivity to ABA in primary root growth compared with the areb1 areb2 abf3 mutant. Genome-wide transcriptome analyses revealed that expression of downstream genes of SRK2D/E/I, which include many genes functioning in osmotic stress responses and tolerance such as transcription factors and LEA proteins, was mostly impaired in the quadruple mutant. Thus, these results indicate that the four AREB/ABFs are the predominant transcription factors downstream of SRK2D/E/I in ABA signalling in response to osmotic stress during vegetative growth.

    In x-ray phase-contrast analyzer-based imaging, the contrast is provided by a combination of absorption, refraction and scattering effects. Several extraction algorithms, which attempt to separate and quantify these different physical contributions, have been proposed and applied. In a previous work, we presented a quantitative comparison of five among the most well-known extraction algorithms based on the geometrical optics approximation applied to planar images: diffraction-enhanced imaging (DEI), extended diffraction-enhanced imaging (E-DEI), generalized diffraction-enhanced imaging (G-DEI), multiple-image radiography (MIR) and Gaussian curve fitting (GCF). In this paper, we compare these algorithms in the case of the computed tomography (CT) modality. The extraction algorithms are applied to analyzer-based CT images of both plastic phantoms and biological samples (cartilage-on-bone cylinders). Absorption, refraction and scattering signals are derived. Results obtained with the different algorithms may vary greatly, especially in the case of large refraction angles. We show that ABI-CT extraction algorithms can provide an excellent tool to enhance the visualization of cartilage internal structures, which may find applications in a clinical context. Besides, by using the refraction images, the refractive index decrements for both the cartilage matrix and the cartilage cells have been estimated. PMID:21113091

    Polycyclic aromatic hydrocarbons (PAHs) are USEPA regulated priority pollutants. Their low aqueous solubility requires very sensitive analytical methods for their detection, typically involving preconcentration steps. Presented is the first demonstrated ‘proof of concept’ use of condensed phase membrane introduction mass spectrometry (CP-MIMS) coupled with direct liquid electron ionization (DEI) for the direct, on-line measurement of PAHs in aqueous samples. DEI is very well suited for the ionization of PAHs and other nonpolar compounds, and is not significantly influenced by the co-elution of matrix components. Linear calibration data for low ppb levels of aqueous naphthalene, anthracene, and pyrene is demonstrated, with measured detection limits of 4 ppb. Analytical response times (t10%–90% signal rise) ranged from 2.8 min for naphthalene to 4.7 min for pyrene. Both intra- and interday reproducibility has been assessed (<3% and 5% RSD, respectively). Direct measurements of ppb level PAHs spiked in a variety of real, complex environmental sample matrices is examined, including natural waters, sea waters, and a hydrocarbon extraction production waste water sample. For these spiked, complex samples, direct PAH measurement by CP-MIMS-DEI yielded minimal signal suppression from sample matrix effects (81%–104%). We demonstrate the use of this analytical approach to directly monitor real-time changes in aqueous PAH concentrations with potential applications for continuous on-line monitoring strategies and binding/adsorption studies in heterogeneous samples.

    Environmental cues play important roles in the regulation of an animal’s physiology and behavior. One such cue, photoperiod, plays an important role in the seasonal acclimatization of birds. It has been demonstrated that an animal’s body mass, basal metabolic rate (BMR), and energy intake, are all affected by photoperiod. The present study was designed to examine photoperiod induced changes in the body mass, metabolism and metabolic organs of the silky starling, Sturnus sericeus. Captive silky starlings increased their body mass and BMR during four weeks of acclimation to a short photoperiod. Birds acclimated to a short photoperiod also increased the mass of certain organs (liver, gizzard and small intestine), and both gross energy intake (GEI) and digestible energy intake (DEI), relative to those acclimated to a long photoperiod. Furthermore, BMR was positively correlated with body mass, liver mass, GEI and DEI. These results suggest that silky starlings increase metabolic thermogenesis when exposed to a short photoperiod by increasing their body and metabolic organ mass, and their GEI and DEI. These findings support the hypothesis that bird species from temperate climates typically display high phenotypic flexibility in thermogenic capacity. PMID:27029864

    A new method in diffraction-enhanced imaging computed tomography (DEI-CT) that follows the idea developed by Chapman et al. [Chapman D, Thomlinson W, Johnston R E, Washburn D, Pisano E, Gmur N, Zhong Z, Menk R, Arfelli F and Sayers D 1997 Phys. Med. Biol. 42 2015] in 1997 is proposed in this paper. Merged with a “reverse projections” algorithm, only two sets of projection datasets at two defined orientations of the analyzer crystal are needed to reconstruct the linear absorption coefficient, the decrement of the real part of the refractive index and the linear scattering coefficient of the sample. Not only does this method reduce the delivered dose to the sample without degrading the image quality, but, compared with the existing DEI-CT approaches, it simplifies data-acquisition procedures. Experimental results confirm the reliability of this new method for DEI-CT applications.

    Conventional radiography only provides a measure of the X-ray attenuation caused by an object; thus, it is insensitive to other inherent informative effects, such as refraction. Furthermore, conventional radiographs are degraded by X-ray scatter that can obscure important details of the object being imaged. The novel X-ray technology diffraction-enhanced imaging (DEI) has recently allowed the visualization of nearly scatter-free images displaying both attenuation and refraction properties. A new method termed multiple-image radiography (MIR) is a significant improvement over DEI, corrects errors in DEI, is more robust to noise and produces an additional image that is entirely new to medical imaging. This new image, which portrays ultra-small-angle X-ray scattering (USAXS) conveys the presence of microstructure in the object, thus differentiating homogeneous tissues from tissues that are irregular on a scale of micrometers. The aim of this study was to examine the use of MIR for evaluation of soft tissue, and in particular to conduct a preliminary investigation of the USAXS image, which has not previously been used in tissue imaging.

    Diabetes is a widespread disease and its control is dependent upon the patient. Although there is no permanent cure for diabetes, there are several available treatments which, when followed regularly, allow the patient to have a good quality of life. Patient education, especially about eating habits, is key to keep glucose levels stable both in the short and in the long term. This should include nutritional counselling, physical exercise, and the self monitoring of glucose levels. The University of Coimbra and the Serviço de Endocrinologia, Diabetes e Metabolismo of Centro Hospitalar e Universitário de Coimbra started a collaboration to develop interactive tools for the learning and improvement of carbohydrate counting by patients. The approach presented in this paper is an interactive multimedia tool, available to patients through either the web or a smartphone. It helps them to learn how to maintain a healthy diet and how to monitor their insulin levels correctly by measuring the carbo-hidrate “equivalents” in meals. This application will create a more dynamic and interactive way of educating patients, improving solutions currently used in the Serviço de Endocrinologia, Diabetes e Metabolismo of the Centro Hospitalar e Universitário de Coimbra.

    The Woodlark rift system is propagating westward into the Australian plate near Papua New Guinea. The current tip is located east of the D'Entrecasteaux Islands (DEI), where very young ultra-high pressure rocks found within metamorphic core complexes suggest rapid exhumation from ~100km depth in < 8 Ma, at rates comparable to extension rates. From March 2010 to July 2011, 31 on-shore and 8 off-shore broadband seismic stations were deployed across the D'Entrecasteaux Islands region to explore the dynamic processes driving the extension and exhumation. We retrieved multi-band (10s - 80s) Rayleigh-wave phase velocity information from both ambient noise and earthquake signals, and estimated the crustal thickness variation using receiver functions (Ps conversion) and the virtual deep seismic sounding method (SsPmp multiple). These observations were inverted for 3D models of crust and mantle shear velocity structure and Moho topography. The Moho topography suggests localized crustal thinning beneath the core complexes on the DEI, relative to the Papuan peninsula to the east and south. The accompanying upper-mantle velocity structure exhibits a slow anomaly (>5%) at shallow depth (Moho to 60km) west of the region of recent extension and exhumation (DEI), while underneath the DEI, the slow anomaly appears to be much deeper (>60km). The shallow low-velocity body in the west roughly parallels both the Trobriand Trench and the Mesozoic-era Australia-Pacific collision zone, and also lies between the current rift tip and the dominant Euler pole (6-0.5Ma) of Woodlark-Australia plate rotation. It may reflect relatively high mantle temperatures beneath the modern (<10Ma) volcanic system that includes Mt. Victory and Mt. Lamington, both of which erupted during the last century. This existing volcanic system may produce a weak zone that helps to localize the extension. As a result, the westward propagation of the Woodlark rift follows and tears apart this volcanic system, and the

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).

    BPA is considering whether to transfer (wheel) electrical power from a proposed privately-owned, combustion-turbine electrical generation plant in Oregon. The plant would be fired by natural gas and would use combined-cycle technology to generate up to 440 average megawatts (aMW) of energy. The plant would be developed, owned, and operated by Portland General Electric Company (PGE). The project would be built in eastern Oregon, just east of the City of Boardman in Morrow County. The proposed plant would be built on a site within the Port of Morrow Industrial Park. The proposed use for the site is consistent with the County land use plan. Building the transmission line needed to interconnect the power plant to BPA`s transmission system would require a variance from Morrow County. BPA would transfer power from the plant to its McNary-Slatt 500-kV transmission line. PGE would pay BPA for wheeling services. Key environmental concerns identified in the scoping process and evaluated in the draft Environmental Impact Statement (DEIS) include these potential impacts: (1) air quality impacts, such as emissions and their contributions to the {open_quotes}greenhouse{close_quotes} effect; (2) health and safety impacts, such as effects of electric and magnetic fields, (3) noise impacts, (4) farmland impacts, (5) water vapor impacts to transportation, (6) economic development and employment impacts, (7) visual impacts, (8) consistency with local comprehensive plans, and (9) water quality and supply impacts, such as the amount of wastewater discharged, and the source and amount of water required to operate the plant. These and other issues are discussed in the DEIS. The proposed project includes features designed to reduce environmental impacts. Based on studies completed for the DEIS, adverse environmental impacts associated with the proposed project were identified, and no evidence emerged to suggest that the proposed action is controversial.

  6. Diffraction-Based Techniques For High Contrast X-ray Imaging

    NASA Astrophysics Data System (ADS)

    Peerzada, Lubna Naseem

    Two X-ray diffraction based techniques for high contrast were explored to improve contrast in radiology: diffraction enhanced imaging (DEI) and coherent scatter imaging. DEI produces contrast in images based upon the difference in the X-ray refractive indices of materials or tissues. Two DEI systems were devised. Both were comprised of a conventional polychromatic copper X-ray source, polycapillary collimating optics and two silicon crystals.Lucite step phantoms and nylon tubing were imaged. No fringe effects were observed. The lack of observable edge enhancement may have been due to the optic structure which obscured refraction effects. Better results might have been achieved if a higher resolution detector or phantom of larger step size or larger diameter thin walled tubing had been used. The second technique was coherent scatter X-ray imaging. The purpose of this work was to differentiate between healthy and diseased human breast tissues. For instance, breast carcinoma is known to have a peak coherent scattering angle at 12.2° for Mo Ka radiation at 17.5 keV, whereas fatty tissue peaks around 9°. A system which would be compatible with screening mammography was developed. The system was expanded to include sample scanning to allow for a larger image area. The modulation transfer function was computed for static and scanned images of a resolution phantom. These showed good agreement, indicating that the scanning was properly aligned and timed. Static and scanned images of phantoms were taken and the contrast was calculated for a series of experimental parameters including, grid tilt angle. A complex phantom was also then imaged. It was possible to distinguish tissue-equivalent phantom types. Good contrast resolution scanned images were obtained which is promising for a diagnostic system.

  7. Development of an x-ray prism for analyzer based imaging systems

    Bewer, Brian; Chapman, Dean

    2010-08-15

    Analyzer crystal based imaging techniques such as diffraction enhanced imaging (DEI) and multiple imaging radiography (MIR) utilize the Bragg peak of perfect crystal diffraction to convert angular changes into intensity changes. These x-ray techniques extend the capability of conventional radiography, which derives image contrast from absorption, by providing large intensity changes for small angle changes introduced from the x-ray beam traversing the sample. Objects that have very little absorption contrast may have considerable refraction and ultrasmall angle x-ray scattering contrast improving visualization and extending the utility of x-ray imaging. To improve on the current DEI technique an x-ray prism (XRP) was designed and included in the imaging system. The XRP allows the analyzer crystal to be aligned anywhere on the rocking curve without physically moving the analyzer from the Bragg angle. By using the XRP to set the rocking curve alignment rather than moving the analyzer crystal physically the needed angle sensitivity is changed from submicroradians for direct mechanical movement of the analyzer crystal to tens of milliradians for movement of the XRP angle. However, this improvement in angle positioning comes at the cost of absorption loss in the XRP and depends on the x-ray energy. In addition to using an XRP for crystal alignment it has the potential for scanning quickly through the entire rocking curve. This has the benefit of collecting all the required data for image reconstruction in a single measurement thereby removing some problems with motion artifacts which remain a concern in current DEI/MIR systems especially for living animals.

  8. Evaluating Safeguards Benefits of Process Monitoring as compared with Nuclear Material Accountancy

    2014-07-01

    This paper illustrates potential safeguards benefits that process monitoring (PM) may have as a diversion deterrent and as a complementary safeguards measure to nuclear material accountancy (NMA). This benefit is illustrated by quantifying the standard deviation associated with detecting a considered material diversion scenario using either an NMA-based method or a PM-based approach. To illustrate the benefits of PM for effective safeguards, we consider a reprocessing facility. We assume that the diversion of interest for detection manifests itself as a loss of Pu caused by abnormally operating a dissolver for an extended period to accomplish protracted diversion (or misdirection) of Pu to a retained (unconditioned) waste stream. For detecting the occurrence of this diversion (which involves anomalous operation of the dissolver), we consider two different data evaluation and integration (DEI) approaches, one based on NMA and the other based on PM. The approach based on PM does not directly do mass balance calculations, but rather monitors for the possible occurrence of anomaly patterns related to potential loss of nuclear material. It is thus assumed that the loss of a given mass amount of nuclear material can be directly associated with the execution of proliferation-driven activities that trigger the occurrence of an anomaly pattern consisting of series of events or signatures occurring at different unit operations and time instances. By effectively assessing these events over time and space, the PM-based DEI approach tries to infer whether this specific pattern of events has occurred and how many times within a given time period. To evaluate the goodness of PM, the 3 Sigma of the estimated mass loss is computed under both DEI approaches as function of the number of input batches processed. Simulation results are discussed.

  9. Dust aerosol emission over the Sahara during summertime from Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) observations

    Dust aerosols are an important component of the climate system and a challenge to incorporate into weather and climate models. Information on the location and magnitude of dust emission remains a key information gap to inform model development. Inadequate surface observations ensure that satellite data remain the primary source of this information over extensive and remote desert regions. Here, we develop estimates of the relative magnitude of active dust emission over the Sahara desert based on data from the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP). Utilising the unique vertical profile of aerosol characteristics provided by CALIOP our algorithm identifies emission from aerosol extinction and lidar backscatter in the near surface layers. From the long-term CALIOP archive of day and night-time orbits over 2006-13 we construct coarse resolution maps of a new dust emission index (DEI) for the Sahara desert during the peak summer dust season (June to September). The spatial structure of DEI indicates highest emission over a broad zone focused on the border regions of Southern Algeria, Northern Mali and northwest Niger, displaced substantially (∼7°) to the east of the mean maximum in satellite-derived aerosol optical depth. In this region night-time emission exceeds that during the day. The DEI maps substantially corroborate recently derived dust source frequency count maps based on back-tracking plumes in high temporal resolution SEVIRI imagery. As such, a convergence of evidence from multiple satellite data sources using independent methods provides an increasingly robust picture of Saharan dust emission sources. Various caveats are considered. As such, quantitative estimates of dust emission may require a synergistic combined multi-sensor analysis.

  10. Informatics in Radiology: Dual-Energy Electronic Cleansing for Fecal-Tagging CT Colonography

    2013-01-01

    Electronic cleansing (EC) is an emerging technique for the removal of tagged fecal materials at fecal-tagging computed tomographic (CT) colonography. However, existing EC methods may generate various types of artifacts that severely impair the quality of the cleansed CT colonographic images. Dual-energy fecal-tagging CT colonography is regarded as a next-generation imaging modality. EC that makes use of dual-energy fecal-tagging CT colonographic images promises to be effective in reducing cleansing artifacts by means of applying the material decomposition capability of dual-energy CT. The dual-energy index (DEI), which is calculated from the relative change in the attenuation values of a material at two different photon energies, is a reliable and effective indicator for differentiating tagged fecal materials from various types of tissues on fecal-tagging CT colonographic images. A DEI-based dual-energy EC scheme uses the DEI to help differentiate the colonic lumen—including the luminal air, tagged fecal materials, and air-tagging mixture—from the colonic soft-tissue structures, and then segments the entire colonic lumen for cleansing of the tagged fecal materials. As a result, dual-energy EC can help identify partial-volume effects in the air-tagging mixture and inhomogeneous tagging in residual fecal materials, the major causes of EC artifacts. This technique has the potential to significantly improve the quality of EC and promises to provide images of a cleansed colon that are free of the artifacts commonly observed with conventional single-energy EC methods. © RSNA, 2013 PMID:23479680

    Diffraction enhanced imaging (DEI) is a new x-ray radiographic imaging modality using synchrotron x-rays which produces images of thick absorbing objects that are almost completely free of scatter. They show dramatically improved contrast over standard imaging applied to the same phantoms. The contrast is based not only on attenuation but also the refraction and diffraction properties of the sample. The diffraction component and the apparent absorption component (absorption plus extinction contrast) can each be determined independently. This imaging method may improve the image quality for medical applications such as mammography.

    The provenance of 37 obsidians from the Kerkennah Islands (central Mediterranean Sea) was determined by PIXE. It is shown that they came from the two main obsidian sources, Balata dei Turchi and Lago di Venere, of the Pantelleria Island. A comparison of the PIXE elemental composition of geological vs. archaeological obsidians of central and western Mediterranean shows that their sources present elemental compositions homogeneous enough to make possible sourcing studies. However, a comparison between the distributions of geological and archaeological obsidians chemistry shows that the PIXE source qualifications do not cover yet the whole of their internal variations.

    Diffraction-enhanced imaging computer tomography (DEI-CT) is a new method to provide the object's inner information. Previous reports demonstrated its applicability in soft and hard tissue imaging. Here, we provide further evidence for the improved overall image quality and for the option to distinguish the inner microstructures of the guinea pig's cochlea. Data has shown the details of the cochlea's inner microstructure such as vestibular membrane which only have 6 μm. A better knowledge of these microstructures may be relevant to achieve progress in the otology of clinical anatomization.

    Two complementary sensors, the DAEDALUS DEI-1260 Multispectral Scanner aboard the NASA U-2 aircraft and the Advanced Very High Resolution Radiometer aboard National Oceanographic and Atmospheric Administration orbiting satellites were tested for their applicability in monitoring and predicting parameters such as fire location, temperature and rate of spread, soil heating and cooling rates, and plume characteristics and dimensions. In addition, the satellite system was tested for its ability to extend the relationships found between fire characteristics and biospheric consequences to regional and global scales. An overall system design is presented, and special requirements are documented for the application of this system for fire research and management.

    In this paper two accounts of Reichenbachian common cause systems are compared. Examples are provided which show that Hofer-Szabó and Rédei (Int J Theor Phys 43:1819-1826, 2004) account and Hofer-Szabó et al. (The principle of the common cause, 2013) account is compatible, with but not equivalent, to Mazzola's (Found Phys 42:512-523, 2012). Moreover, the difference of the two accounts with respect to their explanatory adequacy is discussed, in the light of Salmon's statistical-relevance approach to statistical explanation.

  16. Line x-ray source for diffraction enhanced imaging in clinical and industrial applications

    NASA Astrophysics Data System (ADS)

    Wang, Xiaoqin

    Mammography is one type of imaging modalities that uses a low-dose x-ray or other radiation sources for examination of breasts. It plays a central role in early detection of breast cancers. The material similarity of tumor-cell and health cell, breast implants surgery and other factors, make the breast cancers hard to visualize and detect. Diffraction enhanced imaging (DEI), first proposed and investigated by D. Chapman is a new x-ray radiographic imaging modality using monochromatic x-rays from a synchrotron source, which produced images of thick absorbing objects that are almost completely free of scatter. It shows dramatically improved contrast over standard imaging when applied to the same phantom. The contrast is based not only on attenuation but also on the refraction and diffraction properties of the sample. This imaging method may improve image quality of mammography, other medical applications, industrial radiography for non-destructive testing and x-ray computed tomography. However, the size, and cost, of a synchrotron source limits the application of the new modality to be applicable at clinical levels. This research investigates the feasibility of a designed line x-ray source to produce intensity compatible to synchrotron sources. It is composed of a 2-cm in length tungsten filament, installed on a carbon steel filament cup (backing plate), as the cathode and a stationary oxygen-free copper anode with molybdenum coating on the front surface serves as the target. Characteristic properties of the line x-ray source were computationally studied and the prototype was experimentally investigated. SIMIION code was used to computationally study the electron trajectories emanating from the filament towards the molybdenum target. A Faraday cup on the prototype device, proof-of-principle, was used to measure the distribution of electrons on the target, which compares favorably to computational results.

    This paper reports an example of how the differential PIXE technique can be successfully applied to the investigation of wood or canvas paintings. The work analysed is a famous wood painting by Leonardo da Vinci, the "Madonna dei fusi" (ex-Reford version, 1501), chosen for a pilot study in a wide international project aimed at analysing Leonardo's works of art by means of non-destructive techniques. While illustrating the results obtained concerning the identification of pigments and the discrimination of the stratigraphy of layers, the merits and limits of differential PIXE in general are pointed out.

    An evaluation of Thematic Mapper Simulator (TMS) data for the geobotanical discrimination of rock types based on vegetative cover characteristics is addressed in this research. A methodology for accomplishing this evaluation utilizing univariate and multivariate techniques is presented. TMS data acquired with a Daedalus DEI-1260 multispectral scanner were integrated with vegetation and geologic information for subsequent statistical analyses, which included a chi-square test, an analysis of variance, stepwise discriminant analysis, and Duncan's multiple range test. Results indicate that ultramafic rock types are spectrally separable from nonultramafics based on vegetative cover through the use of statistical analyses.

    The dot-com bubble bursted in the year 2000 followed by a swift movement towards resource virtualization and cloud computing business model. Cloud computing emerged not as new form of computing or network technology but a mere remoulding of existing technologies to suit a new business model. Cloud robotics is understood as adaptation of cloud computing ideas for robotic applications. Current efforts in cloud robotics stress upon developing robots that utilize computing and service infrastructure of the cloud, without debating on the underlying business model. HTM5 is an OMG's MDA based Meta-model for agent oriented development of cloud robotic systems. The trade-view of HTM5 promotes peer-to-peer trade amongst software agents. HTM5 agents represent various cloud entities and implement their business logic on cloud interactions. Trade in a peer-to-peer cloud robotic system is based on relationships and contracts amongst several agent subsets. Electronic Institutions are associations of heterogeneous intelligent agents which interact with each other following predefined norms. In Dynamic Electronic Institutions, the process of formation, reformation and dissolution of institutions is automated leading to run time adaptations in groups of agents. DEIs in agent oriented cloud robotic ecosystems bring order and group intellect. This article presents DEI implementations through HTM5 methodology. PMID:25763310

    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

    In order to study potent microenvironments of malignant gliomas with a high- resolution x-ray imaging technique, an injection orthotopic glioma model was made using the Sprague-Dawley rat. Total brain tissue, taken out as an ex vivo model, was examined with diffraction-enhanced imaging (DEI) computed tomography (CT) acquired with a 35 keV monochromatic x-ray. In the convolution-reconstructed 2D/3D images with a spatial resolution of 12.5 × 12.5 × 25 µm, distinction among necrosis, typical ring-shaped viable tumors, edemas and healthy tissues was clearly observed near the frontal lobe in front of the rat's caudate nucleus. Multiple microvascular proliferations (MVPs) were observed surrounding peritumoral edemas as a tumor infiltration structure. Typical dimensions of tubular MVPs were 130 (diameter) ×250 (length) µm with a partial sprout structure revealed in the 3D reconstructed image. Hyperplasia of cells around vessel walls was revealed with tumor cell infiltration along the perivascular space in microscopic observations of mild MVP during histological analysis. In conclusion, DEI-CT is capable of imaging potent tumor-infiltrating MVP structures surrounding high-grade gliomas.

    A clinical mammography program is in progress at the medical beamline SYRMEP of the Italian synchrotron radiation laboratory ELETTRA in Trieste. A conventional screen-film system is utilized as detector for the examinations on patients. For the next experimental step a digital detector has been designed taking into account the essential requirements for mammography such as high spatial and contrast resolution, high efficiency for low dose examinations and high speed for short acquisition time. A double-layer prototype has already been tested in the frame of the PICASSO project. In addition, an analyzer crystal set-up for Diffraction Enhanced Imaging (DEI) has been available for many years at the SYRMEP beamline. Applying the DEI technique several successful experiments have been carried out in biomedical imaging and in particular in-vitro breast imaging utilizing commercially available detectors. Recently a system upgrade yielded a double-crystal analyzer set-up with improved stability and higher angular resolution. In this study the PICASSO detector has been utilized in combination with the new analyzer set-up for imaging in-vitro breast tissue samples. In order to test the potential of the combined system planar and tomographic images have been acquired and the first results are here presented.

    By using moving split-window techniques (MSWT), this study estimated how far the edge effects penetrated the forest and agricultural fields in the arid valley of upper reaches of Minjiang River, southwestern China. Its aim was to provide general information on vegetation along edge to interior gradients in order to assist in interpretation and prediction of biological phenomena associated with agriculture-forestry boundary, and to improve current management practices in such areas. Three types of boundaries (10 transects) were investigated and sampled. The results showed that when the window width reached 6-10, the change of the SED curve on the graph tended to become stable, and one or two peaks occurred. The depth of edge influence was clearly different for different types of boundaries, and could be estimated within 50 m from the edge to interior. The depth of edge influence (DEI) on vegetation diversity almost varied between 12-30 m, mainly depending on the patch type, topography and microclimate, but seldom on slope orientation. Of the 6 forest transects in the three types of boundaries, the DEI was detected only in the forest part transects M2 and M6, but almost detectable in the agricultural part of all transects. MSWT was considered to be a useful tool for characterizing edge dynamics if enough data was available, and became a simple and powerful technique for analyzing the boundary. The results will provide further knowledge for understanding the interaction between forestry and agriculture in the arid valley. PMID:15624812

    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. PMID:27183512

    Tomosynthesis (TS) is a pseudo-3-dimensional image reconstruction method to recover depth-resolved information using restricted number of projections. In this research, refraction index based TS imaging using dark-field imaging (DFI) optics is proposed and biomedical soft tissues were imaged in low dose exposure. By a single exposure of an object, two projected images are obtained from a Laue-case analyzer of DFI. Calculating the both images refraction component is deduced, while two exposures are needed in DEI (diffraction enhanced imaging). Thus the measurement time and the radiation dose in DFI are half of DEI. In addition, the proposed reconstruction algorithm, derived from the quantitative relationship in measurement process, allows high contrast tomographic imaging in spite of one order smaller number of projections for CT (computed tomography). To demonstrate the proposed imaging protocol efficacy, an ex-vivo excised tissue of human lung were imaged using a system constructed at the vertical wiggler beamline at PF-BL14C at KEK. TS image is successfully delineated high quality soft tissue structures comparable to CT.

    Cataract is a disease that degrades the transparency of crystalline lenses. The crystalline lens is a cellular structure that has a unique shape and protein composition. Cataract is associated with changes in the structure and composition of the lenses. Analyser-based x-ray phase contrast imaging (PCI) is a non-destructive technique that presents images with more contrast and details than the images acquired with conventional synchrotron radiography. Here, an analyser-based x-ray PCI set-up was optimized in the XRD2 beamline at Brazilian Synchrotron Light Laboratory for comparative studies on PCI and conventional synchrotron radiography, for non-cataractous (healthy tissue) and cataractous crystalline (diseased tissue) lenses. Refraction angle and apparent absorption contrast images (diffraction enhanced imaging—DEI) were also obtained. The present PCI and DEI images indicate that the healthy tissue shows enhanced shell structures, while in the diseased tissue these are almost absent. This is associated with the clinical case of total opacity of the cataractous crystalline lenses when it is exposed to visible light.

    This Draft Environmental Impact Statement (DEIS) was prepared by the US Department of Energy (US DOE). The proposed action is the issuance of Presidential Permit PP-89 by DOE to Bangor Hydro-Electric Company to construct and operate a new international transmission line interconnection to New Brunswick, Canada that would consist of an 83.8 mile (US portion), 345-kilovolt (kV) alternating current transmission line from the US-Canadian border at Baileyville, Maine to an existing substation at Orrington, Maine. The principal environmental impacts of the construction and operation of the transmission line would be incremental in nature and would include the conversion of forested uplands (mostly commercial timberlands) and wetlands to right-of-way (small trees, shrubs, and herbaceous vegetation). The proposed line would also result in localized minor to moderate visual impacts and would contribute a minor incremental increase in the exposure of some individuals to electromagnetic fields. This DEIS documents the purpose and need for the proposed action, describes the proposed action and alternatives considered and provides a comparison of the proposed and alternatives routes, and provides detailed information on analyses of the environmental consequences of the proposed action and alternatives, as well as mitigative measures to minimize impacts.

    There is a paucity of dietary data in football referees. In this study, 23 elite main and assistant referees (34.4 ± 5.6 years) completed a 7-day dietary record during the competitive season. No nutritional intake differences were observed between main and assistant referees. Referees' mean daily energy intake (DEI) was 2819 ± 279 kcal. The intake of proteins (1.7 ± 0.2 g · kg(-1)), carbohydrates (4.1 ± 0.8 g · kg(-1)) and fats (1.4 ± 0.2 g · kg(-1)) represented, respectively, 18.4 ± 1.5%, 44.4 ± 4.4% and 34.6 ± 4.1% of the DEI. Carbohydrate intakes before, during and after exercise were 66 ± 42, 7 ± 15 and 120 ± 62 g. Daily carbohydrate, fibre, polyunsaturated fat and water intakes were below recommendations, while fat, saturated fat, cholesterol and sodium intakes were above recommended values. The prevalence of inadequate intake was high for vitamin E (96%), folate (74%), vitamin A (61%), vitamin C (39%), magnesium (26%) and calcium (22%). Carbohydrate intake before, during and after exercise were far from achieving the minimum recommended values. Most referees demonstrated a negligent behaviour of hydration during exercise. Referees would benefit from dietary education in order to optimise performance and health. PMID:24784464

  11. Legends about Legends: Abraham Eleazar's Adaptation of Nicolas Flamel.

    2016-02-01

    This paper explores the relationship between three illustrated alchemical treatises, all of which are associated with Jewish adepts: the famous Le Livre des figures hieroglyphiques attributed to Nicolas Flamel, and two treatises published in 1735 in Erfurt-the Uraltes Chymisches Werckh and the Donum Dei. The Werckh is supposedly written by Rabbi Abraham Eleazar, while the Donum Dei is attributed to an ancient alchemist-cabalist, Rabbi Samuel Baruch. I argue that these authors are fictitious, and that both works were in fact written in the early eighteenth century by their supposed editor, the probably pseudonymous Julius Gervasius. Gervasius connects the Werckh with the legend of Nicolas Flamel by suggesting that it is based on the original, Jewish manuscript which helped Flamel to find the Stone of the Sages. Gervasius used various strategies to confer a sense of Jewish "authenticity" on these works, borrowing from contemporary (non-Jewish) perceptions of Jewish ritual, Hebrew language, and Christian Cabala. The Werckh also borrows and adapts a sequence of allegorical illustrations from those in pseudo-Flamel's Livre, and I compare the two sets of figures and, where possible, interpret them. I conclude that the later works in fact teach us far more about the state of alchemy in the seventeenth and eighteenth centuries than they do about either medieval alchemy or Judaism. PMID:27376176

  12. Ethical issues in astrobiology: a Christian perspective (Invited)

    2009-12-01

    With its focus on the origin, extent, and future of life, Astrobiology raises exciting, multidisciplinary questions for science. At the same time, Astrobiology raises important questions for the humanities. For instance, the prospect of discovering extraterrestrial life - either intelligent or unintelligent - raises questions about humans’ place in the universe and our relationship with nature on planet Earth. Fundamentally, such questions are rooted in our understanding of what it means to be human. From a Christian perspective, the foundational claim about human nature is that all persons bear the "imago dei", the image of God. This concept forms the basis for how humans relate to one another (dignity) and how humans relate to nature (stewardship). For many Christians the "imago dei" also suggests that humans are at the center of the universe. The discovery of extraterrestrial life would be another scientific development - similar to evolution - that essentially de-centers humanity. For some Christian perspectives this de-centering may be problematic, but I will argue that the discovery of extraterrestrial life would actually offer a much needed theological corrective for contemporary Christians’ understanding of the "imago dei". I will make this argument by examining two clusters of ethical issues confronting Astrobiology: 1. What ethical obligations would human explorers owe to extraterrestrial life? Are there ethical obligations to protect extraterrestrial ecosystems from harm or exploitation by human explorers? Do our ethical considerations change, if the extraterrestrial life is a “second genesis;” in other words a form of life completely different and independent from the carbon-based life that we know on Earth? 2. Do we have an ethical obligation to promote life as much as we can? If human explorers discover extraterrestrial life and through examination determine that it is struggling to survive, do we have an ethical obligation to assist that

    Between 2007 and 2010, National Park Service (NPS) staff at the Point Reyes National Seashore, California, collected over 300,000 photographic images of Drakes Estero from remotely operated wildlife monitoring cameras. The purpose of the systems was to obtain photographic data to help understand possible relationships between anthropogenic activities and Pacific harbor seal (Phoca vitulina richardsi) behavior and distribution. The value of the NPS photographs for use in assessing the frequency and impacts of seal disturbance and displacement in Drakes Estero has been debated. In September 2011, the NPS determined that the photographs did not provide meaningful information for development of a Draft Environmental Impact Statement (DEIS) for the Drakes Bay Oyster Company Special Use Permit. Limitations of the photographs included lack of study design, poor photographic quality, inadequate field of view, incomplete estuary coverage, camera obstructions, and weather limitations. The Marine Mammal Commission (MMC) reviewed the scientific data underpinning the Drakes Bay Oyster Company DEIS in November 2011 and recommended further analysis of the NPS photographs for use in characterizing rates and consequences of seal disturbance (Marine Mammal Commission, 2011). In response to that recommendation, the NPS asked the U.S. Geological Survey (USGS) to conduct an independent review of the photographs and render an opinion on the utility of the remote camera data for informing the environmental impact analyses included in the DEIS. In consultation with the NPS, we selected the 2008 photographic dataset for detailed evaluation because it covers a full harbor seal breeding season (March 1 to June 30), provides two fields of view (two cameras were deployed), and represents a time period when cameras were most consistently deployed and maintained. The NPS requested that the photographs be evaluated in absence of other data or information pertaining to seal and human activity in

  14. Low-temperature thermochronologic constraints on cooling and exhumation trends along conjugate margins, within core complexes and eclogite-bearing gneiss domes of the Woodlark rift system of eastern Papua New Guinea

    In eastern Papua New Guinea, active sea-floor spreading within the Woodlark Basin has been propagating westward since at least 6 Ma into heterogeneous crust of the Woodlark Rift. The seafloor spreading system divides the northern conjugate margin (Woodlark Rise) from the southern margin (Pocklington Rise). West of the seafloor spreading rift-tip are high-standing extensional gneiss domes and core complexes of the D'Entrecasteaux Islands (DEI). Domes comprise amphibolite and eclogite-facies gneisses, and Pleistocene granitoid intrusions. Flanked by mylonitic shear zone carapaces and normal faults, the domes are juxtaposed against an upper plate that includes ultramafic rocks and gabbro, correlated with the Papuan ultramafic belt. Petrologic and structural evidence from the DEI has been interpreted as evidence for diapiric ascent of the largely felsic domes, with thermo-mechanical modeling proposing (U)HP exhumation in terms of diapiric flow aided by propagating extension, with feedback between the two. Core complexes lacking evidence for diapiric-aided exhumation include the Prevost Range (eastern Normanby Island), Dayman Dome (Papuan Peninsula), and Misima Island (southern conjugate margin). Thermochronology is being applied to understand the thermal and exhumation history, and hence help constrain mechanisms of (U)HP exhumation. AFT and AHe ages from samples near sea-level along conjugate margins and DEI range from ca. 12 Ma to <1 Ma, generally decreasing from east to west, although with some localized variation. Confined track length distributions (CTLD), obtained using 252Cf implantation, generally indicate rapid cooling (means ≥~14 μm), except on Goodenough Island, the western-most and highest-standing dome. On Goodenough Island, samples from the core zone have AFT ages from ~3 - <1 Ma with age decreasing with decreasing elevation. Core zone samples have mean track lengths (7-13 μm) and are positively skewed, whereas samples from shear zones are younger (<1

    RIASSUNTO. Scopo. Negli ultimi decenni gli studi hanno mostrato come la Teoria della Mente (ToM) non sia un processo unitario, ma un sistema che include aspetti cognitivi e affettivi. Nell'ambito dei domini che definiscono la social cognition, la ToM rappresenta il miglior predittore dello scarso funzionamento sociale nella schizofrenia. Lo scopo del presente lavoro è stato di esaminare la competenza di un gruppo di pazienti ambulatoriali affetti da schizofrenia in compiti di ToM, di riconoscimento di aspetti metaforici e idiomatici del linguaggio, in una prova di rispetto di regole conversazionali e di indagarne la relazione con il funzionamento sociale. Metodi. Sono stati reclutati 30 pazienti ambulatoriali con diagnosi di schizofrenia e 24 controlli sani. Sono stati somministrati il TIB per il calcolo del QI premorboso, la PANSS, il Theory of Mind Picture Sequencing Task, un test di comprensione di metafore e idiomi e un test conversazionale. Il funzionamento sociale è stato valutato con la PSP. Risultati. Non vi era differenza significativa tra i valori medi del QI premorboso del gruppo dei pazienti e dei controlli. Ai test di ToM e di competenza pragmatica, la differenza tra i gruppi è risultata altamente significativa, con i pazienti che hanno eseguito le prove in modo peggiore. È emersa una correlazione tra la comprensione di metafore e idiomi e le false credenze di secondo ordine. La PSP è risultata correlata con la PANSS e con la quota di ToM cognitiva, ma non con la ToM affettiva. Conclusioni. I risultati hanno mostrato che i soggetti affetti da schizofrenia, in condizione clinica di stabilizzazione, hanno evidenti difficoltà nelle prove di ToM e di comprensione del linguaggio figurato. Nel nostro modello teorico, la correlazione evidenziata tra la ToM cognitiva, i deficit pragmatici, lo stato clinico e il livello di funzionamento sociale suggerisce l'utilità di interventi riabilitativi di recupero delle funzioni metacognitive e delle abilit

    Introducción El tejido adiposo blanco (TAB) subcutáneo (Sc) humano podría variar dependiendo de su localización anatómica, con diferencias en su perfil proteómico. Pacientes y métodos Se obtuvieron aspirados de TAB-Sc de seis mujeres con IMC >25 kg/m2, sometidas a liposucción. Dicho TAB-Sc se obtuvo de seis localizaciones anatómicas: abdominal superior e inferior, muslo, dorsal, flanco y cadera, analizándose su perfil proteómico mediante electroforesis bidimensional. En muslo y abdomen superior se compararon, además, las muestras obtenidas de las dos capas del TAB-Sc (profunda y superficial). Resultados Se detectaron 21 proteínas que mostraban una intensidad de expresión diferente entre las seis localizaciones anatómicas y 14 entre las capas superficial y profunda de una misma región. Entre las proteínas identificadas se incluyen: vimentina (proteína estructural); proteínas “heat-shock” (HSPs), superóxido-dismutasa, (estrés/chaperoninas); proteína fijadora de ácidos grasos 4 (FABP-4) y alfa-enolasa (metabolismo lipídico y de los hidratos de carbono, respectivamente) y ATP-sintetasa (producción de energía). Entre las regiones estudiadas, el TAB-Sc dorsal mostraba un perfil proteómico particular, con menor expresión de proteínas implicadas en la producción de energía y metabolismo (ATP-sintetasa, alfa-enolasa, HSPs y FABP-4) que el resto de regiones. Conclusiones Los niveles de expresión de diversas proteínas en el TAB-Sc humano no son homogéneos, difiriendo entre localizaciones anatómicas. Esto sugiere la existencia de diferencias funcionales en el TAB-Sc de acuerdo con su localización anatómica, lo que debe considerarse antes de asumir la extrapolación de los datos derivados del TAB-Sc de una determinada localización al de otras partes de la anatomía.

    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.

    Over the last decade different phase contrast approaches have been exploited at the medical beamline SYRMEP of the synchrotron radiation facility Elettra in Trieste, Italy. In particular special focus has been drawn to analyzer based imaging and the associated imaging theory and processing. Analyzer based Imaging (ABI) and Diffraction Enhanced Imaging (DEI) techniques have been successfully applied in several biomedical applications. Recently it has been suggested to translate the acquired knowledge in this field towards a Thomson Backscattering Source (TBS), which is presently under development at the Frascati National Laboratories of INFN (Istituto Nazionale di Fisica Nucleare) in Rome, Italy. Such source is capable of producing intense and quasi-monochromatic hard X-ray beams. For the technical implementation of biomedical phase imaging at the TBS a grating interferometer for differential phase contrast imaging has been designed and successfully tested at SYRMEP beamline.

    The galactic cosmic ray (GCR) flux is modulated by solar activity: 11 and 22 year cycles are well established. Meteorites offer the possibility of studying longer cycles in the interplanetary space, due to GCR nuclear interactions. 44Ti cosmogenic isotope produced in meteorites is suitable for detecting a century scale modulation. So far reliable measurements of 44Ti in the samples are scarce, the radioisotope concentration being very low. A gamma-ray sensitive spectrometer has been set up in the underground laboratory of Monte dei Cappuccini. The system consists of a 2 kg HPGe detector inside a 28 kg NaI well. The system has a background of approximately 1 count/day (in coincidence mode) in the 44Ti region. We present here the results obtained on the Rio Negro meteorite, which fell in the year 1934.

    In mice with altered body composition, establishing whether it is food intake or energy expenditure, or both, that is the major determinant resulting in changed energy balance is important. In order to ascertain where the imbalance is, the acquisition of reproducible data is critical. Therefore, here we provide detailed descriptions of how to determine energy balance in mice. This encompasses protocols for establishing energy intake from home cage measurement of food intake, determining energy lost in feces using bomb calorimetry, and using equations to calculate parameters such as energy intake (EI), digested energy intake (DEI), and metabolisable energy intake (MEI) to determine overall energy balance. We also discuss considerations that should be taken into account when planning these experiments, including diet and sample sizes. © 2016 by John Wiley & Sons, Inc. PMID:27584551

    The passive film formed on 2205 duplex stainless steel (DSS) in 0.5 M NaHCO3+0.5 M NaCl aqueous solution was characterized by electrochemical measurements, including potentiodynamic anodic polarization and dynamic electrochemical impedance spectroscopy (DEIS). The results demonstrate that there is a great difference between the passive film evolutions of ferrite and austenite. The impedance values of ferrite are higher than those of austenite. The impedance peaks of ferritic and austenitic phases correspond to the potential of 0.15 and 0.25 V in the low potential range and correspond to 0.8 and 0.75 V in the high potential range. The evolutions of the capacitance of both phases are reverse compared to the evolutions of impedance. The thickness variations obtained from capacitance agree well with those of impedance analysis. The results can be used to explain why pitting corrosion occurs more easily in austenite phase than in ferrite phase.

    2011-08-01

    Realistic HIV models tend to be rather complex and many recent models proposed in the literature could not yet be analyzed by traditional identifiability testing techniques. In this paper, we check a priori global identifiability of some of these nonlinear HIV models taken from the recent literature, by using a differential algebra algorithm based on previous work of the author. The algorithm is implemented in a software tool, called DAISY (Differential Algebra for Identifiability of SYstems), which has been recently released (DAISY is freely available on the web site http://www.dei.unipd.it/~pia/ ). The software can be used to automatically check global identifiability of (linear and) nonlinear models described by polynomial or rational differential equations, thus providing a general and reliable tool to test global identifiability of several HIV models proposed in the literature. It can be used by researchers with a minimum of mathematical background. PMID:20953911

    The discovery of the asteroid Ceres by Piazzi in 1801 motivated the development of a mathematical technique proposed by Gauss, (Theory of the Motion of the Heavenly Bodies Moving about the Sun in Conic Sections, 1963) which allows to recover the orbit of a celestial body starting from a minimum of three observations. Here we compare the method proposed by Gauss (Theory of the Motion of the Heavenly Bodies Moving about the Sun in Conic Sections, New York, 1963) with the techniques (based on three observations) developed by Laplace (Collected Works 10, 93 146, 1780) and by Mossotti (Memoria Postuma, 1866). We also consider another method developed by Mossotti (Nuova analisi del problema di determinare le orbite dei corpi celesti, 1816 1818), based on four observations. We provide a theoretical and numerical comparison among the different procedures. As an application, we consider the computation of the orbit of the asteroid Juno.

    The new X-ray radiography imaging technique, named diffraction enhanced imaging (DEI), enables almost scatter free absorption imaging, the production of the so-called refraction images of a sample. The images show improved contrast compared to standard imaging applications. At the HASYLAB wiggler beamline W2 at the 2nd-generation storage ring DORIS a 5cm wide beam with an adjustable energy between 10 and 70keV is available. A Si [111] pre-monochromator is used followed by the main monochromator using the (111) or the (333)-reflection. Visualization of fossils, detecting internal pearl structures, monitoring of bone and cartilage and documentation of implant healing in bone are application examples at HASYLAB.

    A collection of more than 1800 carbonized papyri, discovered in the Roman 'Villa dei Papiri' at Herculaneum is the unique classical library survived from antiquity. These papyri were charred during 79 A.D. Vesuvius eruption, a circumstance which providentially preserved them until now. This magnificent collection contains an impressive amount of treatises by Greek philosophers and, especially, Philodemus of Gadara, an Epicurean thinker of 1st century BC. We read many portions of text hidden inside carbonized Herculaneum papyri using enhanced X-ray phase-contrast tomography non-destructive technique and a new set of numerical algorithms for 'virtual-unrolling'. Our success lies in revealing the largest portion of Greek text ever detected so far inside unopened scrolls, with unprecedented spatial resolution and contrast, all without damaging these precious historical manuscripts. Parts of text have been decoded and the 'voice' of the Epicurean philosopher Philodemus is brought back again after 2000 years from Herculaneum papyri. PMID:27265417

    Section 643 of the Energy Security Act of 1980 directed the Federal Energy Regulatory Commission to develop rules to further encourage geothermal development by Small Power Production Facilities. This rule amends rules previously established in Dockets No. RM79-54 and 55 under Section 201 and 210 of the Public Utility Regulatory Policies Act of 1978 (PURPA). The analysis shows that the rules are expected to stimulate the development of up to 1,200 MW of capacity for electrical generation from geothermal facilities by 1995--1,110 MW more than predicted in the original PURPA EIS. This Final Supplemental EIS to the DEIS, issued by FERC in June 1980, forecasts likely near term development and analyzes environmental effects anticipated to occur due to development of geothermal resources in the Western United States as a result of this additional rulemaking.

    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.

    Cosmogenic isotopes produced by galactic cosmic rays (GCR) in meteorites offer the opportunity to reveal the heliospheric magnetic field modulation in the interplanetary space between heliocentric distances of 1 and 3 AU. We present the gamma-activity measurement of Agen meteorite, a H5 chondrite that fell on September 5, 1814 in Aquitaine, France. Its 44Ti activity reflects GCR flux integrated since the mid of 1700 to the time of fall and confirms the decreasing trend of GCR flux that we previously suggested on the basis of measurements of other meteorites which fell in the last 250 years as well as the centennial modulation of GCR due to the Gleissberg solar cycle This result was obtained thanks to the high-efficiency and selective configuration of the gamma-ray spectrometer (HPGe+NaI) operating at the underground Laboratory of Monte dei Cappuccini (OATo, INAF) in Torino, Italy.

    Refraction-contrast computed tomography (CT) can image biological soft tissues and soft materials at a high contrast, which cannot be clearly depicted by contemporary CT based on absorption contrast. It reconstructs a distribution of refractive index from projections, whose data each is an angular deviation from incident direction due to refraction by an object, and is acquired by imaging methods using an angular analyzer, e.g., DEI (diffraction enhance imaging), or DFI (dark field imaging). First, a reconstruction algorithm for refraction-contrast CT is derived from the ray equation of a fundamental equation describing refraction phenomena in geometrical optics. Then, in order to demonstrate its efficacy, we performed imaging experiment using DFI-CT imaging system. A reconstructed image of human breast cancer tissue is presented.

    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.

    Syphilis arrived in Bologna in the summer of 1495, after Fornovo's battle on the Taro where Charles VIII's army, following the invasion of Naples, fought against the anti-French league who faced up to the invaders as they withdrew. It was the battle-weary Bolognesi, prisoners, deserters and probably some prostitutes following the French and mercenary army who introduced the infection into the city. At the beginning of the syphilis epidemic, the disease was very aggressive with particularly visible symptoms and many resulting deaths. Subsequently, contemporaries mention an abatement of this aggressivity in time spans that varied, but in no cases exceeded 60 years. In 1507 Bologna lost its political autonomy, becoming dependent on Rome. This was symptomatic of the upheavals throughout Italy in the sixteenth century. In this situation of economic and institutional crisis the Bolognesi were able to react with decision to the epidemic, re-converting the municipal hospital dedicated to S. Maria dei Guarini during the sixteenth century. This hospital, specializing in treating syphilis, was called "Ospedale di San Giobbe". It was closed in 1798, after the entry of the French army into Bologna. In 1560 the Bolognesi, realising that the most important causes of the spread of syphilis were social degradation, prostitution and poverty, founded another institution for the poor and for the prevention of prostitution. This institution was developed by the Opera dei Mendicanti and provided hospitality during the 1590 famine, in a city of 55,000 inhabitants, for as many as 1400 poor and sick. We also present the cure (guaiac and mercury) that they used at the time against syphilis. In such a difficult historical period beset with political and economic problems, the Bolognesi established two important institutions and showed that social solidarity is a value for the whole population.

    Conventional radiography produces a single image of an object by measuring the attenuation of an x-ray beam passing through it. When imaging weakly absorbing tissues, x-ray attenuation may be a suboptimal signature of disease-related information. In this paper we describe a new phase-sensitive imaging method, called multiple-image radiography (MIR), which is an improvement on a prior technique called diffraction-enhanced imaging (DEI). This paper elaborates on our initial presentation of the idea in Wernick et al (2002 Proc. Int. Symp. Biomed. Imaging pp 129-32). MIR simultaneously produces several images from a set of measurements made with a single x-ray beam. Specifically, MIR yields three images depicting separately the effects of refraction, ultra-small-angle scatter and attenuation by the object. All three images have good contrast, in part because they are virtually immune from degradation due to scatter at higher angles. MIR also yields a very comprehensive object description, consisting of the angular intensity spectrum of a transmitted x-ray beam at every image pixel, within a narrow angular range. Our experiments are based on data acquired using a synchrotron light source; however, in preparation for more practical implementations using conventional x-ray sources, we develop and evaluate algorithms designed for Poisson noise, which is characteristic of photon-limited imaging. The results suggest that MIR is capable of operating at low photon count levels, therefore the method shows promise for use with conventional x-ray sources. The results also show that, in addition to producing new types of object descriptions, MIR produces substantially more accurate images than its predecessor, DEI. MIR results are shown in the form of planar images of a phantom and a biological specimen. A preliminary demonstration of the use of MIR for computed tomography is also presented.

    It has been suggested that large foregut-fermenting marsupial herbivores, the kangaroos and their relatives, may be less constrained by food intake limitations as compared with ruminants, due mainly to differences in their digestive morphology and management of ingesta particles through the gut. In particular, as the quality of forage declines with increasing contents of plant fibre (cellulose, hemicelluloses and lignin; measured as neutral-detergent fibre, NDF), the tubiform foregut of kangaroos may allow these animals to maintain food intakes more so than ruminants like sheep, which appear to be limited by fibrous bulk filling the foregut and truncating further ingestion. Using available data on dry matter intake (DMI, g kg(-0.75) d(-1)), ingesta mean retention time (MRT, h), and apparent digestibility, we modelled digestible dry matter intake (DDMI) and digestible energy intake (DEI) by ruminant sheep (Ovis aries) and by the largest marsupial herbivore, the red kangaroo (Macropus rufus). Sheep achieved higher MRTs on similar DMIs, and hence sheep achieved higher DDMIs for any given level of DMI as compared with kangaroos. Interestingly, MRT declined in response to increasing DMI in a similar pattern for both species, and the association between DMI and plant NDF contents did not support the hypothesis that kangaroos are less affected by increasing fibre relative to sheep. However, when DEI was modelled according to DDMIs and dietary energy contents, we show that the kangaroos could meet their daily maintenance energy requirements (MER) at lower levels of DMI and on diets with higher fibre contents compared with sheep, due largely to the kangaroos' lower absolute maintenance and basal energy metabolisms compared with eutherians. These results suggest that differences in the metabolic set-point of different species can have profound effects on their nutritional niche, even when their digestive constraints are similar, as was the case for these ruminant and non

    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.

    In tissue engineering, non-invasive imaging of biomaterial scaffolds and tissues in living systems is essential to longitudinal animal studies for assessments without interrupting the repair process. Conventional X-ray imaging is inadequate for use in soft tissue engineering due to the limited absorption difference between the soft tissue and biomaterial scaffolds. X-ray phase-based imaging techniques that derive contrast from refraction or phase effects rather than absorption can provide the necessary contrast to see low-density biomaterial scaffolds and tissues in large living systems. This paper explores and compares three synchrotron phase-based X-ray imaging techniques-computed tomography (CT)-diffraction enhanced imaging (DEI), -analyzer based imaging (ABI), and -phase contrast imaging (PCI)-for visualization and characterization of low-density biomaterial scaffolds and tissues in situ for non-invasive soft tissue engineering assessments. Intact pig joints implanted with polycaprolactone scaffolds were used as the model to assess and compare the imaging techniques in terms of different qualitative and quantitative criteria. For long-term in vivo live animal imaging, different strategies for reducing the imaging radiation dose and scan time-reduced number of CT projections, region of interest, and low resolution imaging-were examined with the presented phase-based imaging techniques. The results demonstrated promising capabilities of the phase-based techniques for visualization of biomaterial scaffolds and soft tissues in situ. The low-dose imaging strategies were illustrated effective for reducing the radiation dose to levels appropriate for live animal imaging. The comparison among the imaging techniques suggested that CT-DEI has the highest efficiency in retaining image contrast at considerably low radiation doses. PMID:26761779

    The work makes use of surname analysis, repeated pairs and kinship estimates in 11,009 marriage records celebrated in five communities of the Italian Central Apennine (Celano, Lecce dei Marsi, Ortucchio, Roio, Villavallelonga) from 1802 to 1965 with the objective to deepen knowledge of the relative influence of several determinants on their marital behaviour. These towns are part of the same geographic and economic environment: the slopes of the ancient Fucino Lake. This work further elaborates the results from previous studies on the bio-demographic model of the region. The data were analyzed according to three periods of approximately 50 years. Results show the highest inbreeding coefficients in the pastoral towns of Roio and Villavallelonga. Repeated pair analysis highlights a certain degree of population subdivision which declined in time in Celano, Lecce dei Marsi and Ortucchio. The highest and increasing values of RP-RPr in time in Roio suggest a general reduction in genetic heterogeneity. This is possibly due to the celebration of marriages among families selected on the economic basis of pastoralism, as this town historically has had a leading tradition of sheep-farming. Villavallelonga, excluding isonymous marriages, shows an increase in repeated pair unions in time, thus revealing a substructure with marriages among preferred lineages. This is in line with previous results on consanguineous marriages which indicated the tendency of avoiding unions between close relatives in this small geographic isolate. This study demonstrates the influence of geographical (altitude) and social factors (pastoralism) on the marital structures of the investigated populations. PMID:24012323

    Background Driver error and inadequate skill are common critical reasons for novice teen driver crashes, yet few validated, standardized assessments of teen driving skills exist. The purpose of this study was to evaluate the construct and criterion validity of a newly developed Simulated Driving Assessment (SDA) for novice teen drivers. Methods The SDA's 35-minute simulated drive incorporates 22 variations of the most common teen driver crash configurations. Driving performance was compared for 21 inexperienced teens (age 16–17 years, provisional license ≤90 days) and 17 experienced adults (age 25–50 years, license ≥5 years, drove ≥100 miles per week, no collisions or moving violations ≤3 years). SDA driving performance (Error Score) was based on driving safety measures derived from simulator and eye-tracking data. Negative driving outcomes included simulated collisions or run-off-the-road incidents. A professional driving evaluator/instructor reviewed videos of SDA performance (DEI Score). Results The SDA demonstrated construct validity: 1.) Teens had a higher Error Score than adults (30 vs. 13, p=0.02); 2.) For each additional error committed, the relative risk of a participant's propensity for a simulated negative driving outcome increased by 8% (95% CI: 1.05–1.10, p<0.01). The SDA demonstrated criterion validity: Error Score was correlated with DEI Score (r=−0.66, p<0.001). Conclusions This study supports the concept of validated simulated driving tests like the SDA to assess novice driver skill in complex and hazardous driving scenarios. The SDA, as a standard protocol to evaluate teen driver performance, has the potential to facilitate screening and assessment of teen driving readiness and could be used to guide targeted skill training.

This article presents the prokaryotic origin of the organelle and the relation between nuclear and mitochondrial genomes, as well as current evolutionary models for such mechanisms. It also addresses the structure of mitochondrial genes, their expression pattern, clinical features of gene defects, risk of transmission and current techniques to avoid these events in assisted human reproduction. Finally, it discusses the ethical implications of these possibilities.RESUMOAs doenças genéticas mitocondriais são responsáveis pelos erros inatos do metabolismo mais comuns, causados por mutações tanto em genes nucleares como no DNA mitocondrial.

    2011-03-30

    Negli ultimi anni sono state introdotte in urologia nuove tecniche chirurgiche alcune già applicabili nella pratica clinica, altre ancora in corso di sperimentazione. Quella che ha trovato attualmente applicazione è la LESS (Laparo Endoscopic Single-site Surgery); essa riguarda tutte le metodiche che utilizzano una sola porta (multiaccesso) per eseguire interventi laparoscopici. I vantaggi apparenti di questa metodica rispetto alla laparoscopia tradizionale sono soltanto un dimostrato miglior risultato estetico. Mancano studi prospettici randomizzati. NOTES (Natural Orifices Transluminal Endoscopic Surgery) È una metodica ancor più nuova che sfrutta gli orifizi naturali (bocca, retto, vagina, vescica per accedere alla cavità addominale. Rispetto alla LESS questa tecnica utilizza prevalentemente i gastroscopi e lo strumentario dei gastoenterologi per eseguire interventi demolitivi. In urologia l'impiego di questa metodica è puramente sperimentale, comunque piccoli passi sono stati fatti nel migliorare lo strumentario. I chirurghi stanno consolidando questa metodica sull'uomo riguardo alla colecistectomia, ma i risultati sono scarsi, discordanti sulla via d'accesso e limitati a case reports. Oggi i risultati più incoraggianti li ha descritti Estevao Lima, un ingegnoso portoghese che utilizzando una tecnica NOTES di terza generazione (accesso combinato trans-vescicale e trans-gastrico) è riuscito ad eseguire una serie di nefrectomie sul maiale. Tanto si sa e si è speculato riguardo al robot da Vinci®, che oggi la prostatectomia senza di lui non è più competitiva. Moltissimi sono i centri che lo hanno, molti quelli che lo usano, tanti quelli che hanno risultati migliori rispetto alla tecnica laparoscopica classica. Ancora ad oggi però non esistono studi prospettici randomizzati che dimostrino la sua superiorità; inoltre una spina nel fianco sono i costi. Un ulteriore sviluppo futuro di da Vinci® forse potrebbe vedersi nell'assistere le nuove tecniche

    RIASSUNTO Introduzione I parametri di pressione arteriosa, sistolica (PAS) o diastolica (PAD) hanno costituito I’oggetto di numerosi studi, alcuni dei quali stabiliscono un’associazione tra I’aumnto di tali parametri e la mortalità, in particolare alle età medie. I fattori di rischio di ipertensione più frequentemente studiati sono il consumo di alcol, il fumo e I’origine etnica in riferimento sia alle differenze genetiche che nella condotta alimentare, mentre i fattori di origine professionale sono stati presi in considerazione più raramente e in maniera poco approfondita, inoltre sono state riferite notevoli differenze nelle pressioni arteriose medie di individui che svolgono professioni diverse. Sembra infatti che i “colletti blu” siano più a rischio dei “colletti bianchi”. Obiettivi Il nostro scopo è valutare se determinati rischi o vincoli connessi con l’attività professionale o determinati stili di vita rappresentano un fattore di rischio per l’ipertensione arteriosa in considerazioni dell’aumentare dell’età. Elementi specifici che rendano conto di questa relazione non sono stati ancora completamente chiariti e soprattutto i dati sulla popolazione italiana sono molto limitati. Metodi La metodologia di ricerca utilizzata è stata quella dell’indagine francese ESTEV (Derriennic, Touranchet, Volkoff) - VISAT (Marquie, Janson), studio epidemiologico longitudinale su oltre 23000 lavoratori attivata in Francia nel 1990 al fine di indagare gli effetti a lungo termine delle condizioni di lavoro, riferite all’intera vita professionale, sia sull’invecchiamento sia sulla salute dei lavoratori. Analoga indagine è stata avviata in Italia, nel 2000, in 6 Regioni, prendendo in esame i lavoratori dipendenti di diversi settori produttivi appartenenti a 5 coorti di età: da 32 a 52 anni con intervallo di 5 anni.

El nivel de betatrofina en suero fue evaluado mediante ensayo por inmunoabsorción ligado a enzimas. Se midieron las concentraciones en suero de 12 adipoquinas para evaluar las asociaciones con la betatrofina usando los kits comerciales Adipokine Magnetic Bead Panel. Los análisis estadísticos incluyeron correlación bivariada, análisis de curva ROC y análisis de regresión lineal multivariable. Resultados: el nivel de betatrofina en suero fue más elevado en pacientes con síndrome metabólico (997,36 ± 475,92 pg/ml, p = 0,001) que en los controles (735,35 ± 526,51 pg/ml). Frente al tercil más bajo, el tercil más alto del nivel de betatrofina mostró una asociación con mayor riesgo de síndrome metabólico (odds ratio ajustado = 3,521, intervalo de confianza [IC] 95% [1,191-10,413], p = 0,023). Se desarrolló la curva ROC de betatrofina para pronosticar la presencia de síndrome metabólico (área bajo la curva ROC = 0,682 [95% IC, 0,597-0,767], p < 0,001). Además, la betatrofina mostró correlación con distintos parámetros, como edad (r = 0,286, p < 0,001), índice de masa corporal (r = 0,160, p = 0,046), índice cintura-cadera (r = 0,241, p = 0,002), lipoproteína de alta densidad (r = -0,167, p = 0,037), lipoproteína de baja densidad (r = -0,195, p = 0,015), glucosa plasmática en ayunas (r = 0,266, p = 0,001), hemoglobina A1C (r = 0,314, p < 0,001), índice de resistencia a la insulina mediante HOMA (r = 0,272, p = 0,001) y diversas adipoquinas, entre ellas resistina (r = 0,571, p < 0,001), interleucina-8 (r = 0,435, p < 0,001), factor de necrosis tumoral alfa (r = 0,295, p = 0,011) y

    The gulf of Palermo is long about 30 km and the coast is closed between two headlands, Monte Gallo Cape (western side) and Zafferano Cape (east side). The continental shelf is linked with the abyssal plan by an high slope and the depth is included between 50 m and 1500 m. The shape of the Palermo gulf is the answer of both the natural forces and human activity. Nevertheless the coastal morphologies reproduce the geological setting of this area. The coast is divided in two morphotypes, low and rocky coast and beaches. Respectively composed by compact limestone and calcareous incoherent sediment with common sandy granulometry. The beaches, compressively long 11,46 km, are different in lengths, amplitude and lithological types (30% sandy and 70 % sandy-pebbly). In order to study the coastal evolution it is important to define all the coastal dynamics. The coastal evolution is actually the result of complex and intertwined action of both natural and/or anthropic processes. Nowday in the gulf of Palermo these processes exist and in some case they already triggered erosive phenomena. The westernmost beaches is the famous Mondello beach, it is made of pale sand and with sloping very low. This section of coast as other similar beaches (Arenella, Romagnolo and Acqua dei Corsari) has gone through remarkable dynamic phenomena. More precisely between 1976 and 1992 the beach (known as Arenella beach), beyond the Palermo harbor, advanced its shoreline position. Going further west along the coast one can find a landfill, partially collapsed and eroded by the impact of sea storms, that contributes to the coastal advancement from West towards East. At Romagnolo coast zone the beach has advanced because of the debris coming from local landfills, instead the Acqua dei Corsari beach (pebbles and sand) has been going through various fluctuations with a general trend towards advancement due to the longitudinal sediment transport. The study analyze the nature of sediments that made the

    The Yucca Mountain Transportation Database was developed as a data management tool for assembling and integrating data from multiple sources to compile the potential transportation impacts presented in the Draft Environmental Impact Statement for a Geologic Repository for the Disposal of Spent Nuclear Fuel and High-Level Radioactive Waste at Yucca Mountain, Nye County, Nevada (DEIS). The database uses the results from existing models and codes such as RADTRAN, RISKIND, INTERLINE, and HIGHWAY to estimate transportation-related impacts of transporting spent nuclear fuel and high-level radioactive waste from commercial reactors and U. S. Department of Energy (DOE) facilities to Yucca Mountain. The source tables in the database are compendiums of information from many diverse sources including: radionuclide quantities for each waste type; route and route characteristics for rail, legal-weight truck, heavy haul. truck, and barge transport options; state-specific accident and fatality rates for routes selected for analysis; packaging and shipment data by waste type; unit risk factors; the complex behavior of the packaged waste forms in severe transport accidents; and the effects of exposure to radiation or the isotopic specific effects of radionclides should they be released in severe transportation accidents. The database works together with the codes RADTRAN (Neuhauser, et al, 1994) and RISKlND (Yuan, et al, 1995) to calculate incident-free dose and accident risk. For the incident-free transportation scenario, the database uses RADTRAN and RISKIND-generated data to calculate doses to offlink populations, onlink populations, people at stops, crews, inspectors, workers at intermodal transfer stations, guards at overnight stops, and escorts, as well as non-radioactive pollution health effects. For accident scenarios, the database uses RADTRAN-generated data to calculate dose risks based on ingestion, inhalation, resuspension, immersion (cloudshine), and groundshine as

    High blood pressure and cognitive impairment often coexist in old age, but their pathophysiological association is complex. Several longitudinal studies have shown that high blood pressure at midlife is a risk factor for cognitive impairment and dementia, although this association is much less clear in old age. The effect of blood pressure lowering in reducing the risk of dementia is only borderline significant in clinical trials of older subjects, partly due to the insufficient follow-up time. Conversely, dementia onset is associated with a decrease of blood pressure values, probably secondary to neurodegeneration. Prognostic effect of blood pressure values in cognitively impaired older subjects is still unclear, with aggressive blood pressure lowering being potentially harmful in this patients category. Brief cognitive screening, coupled with simple motor assessment, are warranted to identify frail older subjects who need a more cautious approach to antihypertensive treatment. Values obtained with ambulatory blood pressure monitoring seem more useful than clinical ones to predict the outcome of cognitively impaired older subjects. Future studies should identify the most appropriate blood pressure targets in older subjects with cognitive impairment. RiassuntoIpertensione arteriosa e decadimento cognitivo spesso coesistono in età avanzata, sebbene la loro associazione sia complessa dal punto di vista fisiopatologico. Diversi studi longitudinali hanno mostrato che elevati valori pressori in età adulta rappresentano un fattore di rischio per decadimento cognitivo e demenza, sebbene tale associazione sia molto meno chiara in età avanzata. L'effetto della terapia antiipertensiva è risultato ai limiti della significatività statistica nel ridurre il rischio di demenza negli studi di intervento su soggetti anziani, in parte a causa della durata insufficiente del follow-up. D'altra parte, l'insorgenza di demenza è associata con una riduzione dei valori pressori

    This paper provides a description of the current status regarding the proposed development of a rail line to the Yucca Mountain Nuclear Waste Repository in Nye County, Southern Nevada, which includes potential impacts analyzed during the National Environmental Policy Act (NEPA) process, and the subsequent creation of an Environmental Impact Statement (EIS) for the rail line. Potential impacts are addressed within the context of impacts to natural and human environmental resources found within the geographic area of the proposed federal project. Potential impacts to these resources have been fully analyzed in the Rail Alignment Draft EIS (DEIS). This paper includes a summary of the potential impacts analyzed in the DEIS. Examples of potential impacts include land use conflicts, air quality, water use, and impacts to biological and cultural resources, among others. In conclusion: Based on its obligations under the NWPA and its decision to select the mostly rail scenario for the transportation of spent nuclear fuel and high-level radioactive waste, DOE needs to ship these materials by rail in Nevada to a repository at Yucca Mountain. DOE prepared the Rail Alignment EIS to provide the background, data, information, and analyses to help decision makers and the public understand the potential environmental impacts that could result from constructing and operating a railroad for shipment of spent nuclear fuel, high-level radioactive waste, and other materials from an existing rail line in Nevada to a repository at Yucca Mountain. This railroad would consist of a rail line, railroad operations support facilities, and other related infrastructure. DOE will use the Rail Alignment EIS to decide whether to construct and operate the proposed railroad, and if so, to: - Select a rail alignment (Caliente rail alignment or Mina rail alignment) in which to construct the railroad; - Select the common segments and alternative segments within either a Caliente rail alignment or a Mina

    Radiance measurements from handheld (Exotech 100-A) and air-borne (Daedalus DEI 1260) radiometers were related to wheat (Triticum aestivum L.) stand densities (simulated winter wheat winterkill) and to grain yield for a field located 11 km northwest of Sidney, Montana, on a Williams loam soil (fine-loamy, mixed Typic Argiborolls) where a semidwarf hard red spring wheat cultivar was needed to stand. Radiances were measured with the handheld radiometer on clear mornings throughout the growing season. Aircraft overflight measurements were made at the end of tillering and during the early stem extension period, and the mid-heading period. The IR/red ratio and normalized difference vegetation index were used in the analysis. The aircraft measurements corroborated the ground measurements inasmuch as wheat stand densities were detected and could be evaluated at an early enough growth stage to make management decision. The aircraft measurements also corroborated handheld measurements when related to yield prediction. The IR/red ratio, although there was some growth stage dependency, related well to yield when measured from just past tillering until about the watery-ripe stage.

    In clinical research, many potentially useful variables are available via the routine activity of cancer center-based clinical registries (CCCR). We present the experience of the breast cancer clinical registry at Fondazione IRCCS "Istituto Nazionale dei Tumori" to give an example of how a CCCR can be planned, implemented, and used. Five criteria were taken into consideration while planning our CCCR: (a) available clinical and administrative databases ought to be exploited to the maximum extent; (b) open source software should be used; (c) a Web-based interface must be designed; (d) CCCR data must be compatible with population-based cancer registry data; (e) CCCR must be an open system, able to be connected with other data repositories. The amount of work needed for the implementation of a CCCR is inversely linked with the amount of available coded data: the fewer data are available in the input databases as coded variables, the more work will be necessary, for information technology staff, text mining analysis, and registrars (for collecting data from clinical records). A cancer registry in a comprehensive cancer center can be used for several research aspects, such as estimate of the number of cases needed for clinical studies, assessment of biobank specimens with specific characteristics, evaluation of clinical practice and adhesion to clinical guidelines, comparative studies between clinical and population sets of patients, studies on cancer prognosis, and studies on cancer survivorship.

    Ceiling reflection sundials employ a small horizontal mirror, say on a south-facing window sill, to cast a spot of sunlight to the ceiling and/or walls of a room or gallery. In this way the linear scale of the daily and annual motions of the sun are greatly amplified, allowing a plethora of information to be displayed and read. Besides the time of day and the date, typical quantities included the altitude and azimuth of the sun, the declination of the sun, the number of hours since sunrise, the length of daylight, the sign of the zodiac, the sidereal time, etc. The principles for planning and calculating these sundials were first laid out in detail in 17th century Italy by the Jesuit scholars Athanasius Kircher and Emmanuel Maignan: two reflection dials of the latter still survive today in Rome, at Trinità dei Monti (1637) and Palazzo Spada (1644). A third extant example can be found at the Lycée Stendhal in Grenoble, built by a Jesuit priest named Bonfa in 1673. This talk will describe and illustrate these complex sundials, as well as a recently completed ceiling dial, inspired by their example, in the New World (Seattle).

    The collections of the MaZuranić-Brlić-RuZić Memorial Library and Archive in Rijeka contain in addition to the libraries of Ivan, Antun and Matija Mazuranic and of Baron Kuslan, books from the library of Dimitrija Demeter. This Graeco-Croatian man of letters and doctor of medicine was the first modern Croatian playwright. Artefacts, paintings and furniture of the Demeter family are included in the collection, as well as books. Dimitrija Demeter (1811-1872), the son of Afratia and Theodor Demeter, was born into an affluent merchant family in Zagreb in 1811. His two sisters were to marry respected men from Croatian political and cultural life and his brothers became successful business men and founders of Lloyd Triestino. Dimitrija, however, initially devoted himself to science, studying at the medical faculty in Padua, where he graduated in 1834. In 1836 he received his doctorate, on the theme of meningitis. He later became one of the leading figures of the Croatian National Awakening. His main contributions were as an editor and playwright and he is widely regarded as the founder of modern Croatian drama. Not only did he write the plays 'The Field of Grobnik' and 'Teuta', publish articles and edit 'Danica', but he was a driving force behind, and promoter of, the Croatian theatre on St Mark's Square in Zagreb. A portrait of Dimitrija Demeter can still be seen in the Galileo Chamber (dei magnifici quaranta) at the University of Padua, immediately behind the famous Galileo Galilei platform. PMID:20102245

    First Academies originated in Italy at the beginnings of the Renaissance. Their works were of encyclopedic extent. Regarding to scientific academies, the first was the "Accademia dei Lincei" founded in Rome on August 17, 1603, due to the initiative of four young men; three naturalists and a physician. Later, several distiguished scientists were admitted, such as Giambattista della Porta, inventor of the dark chamber (1610) and Galileo Galilei (1611). This Academy sponsored the publication of a compendium of Francisco Hernández manuscripts, prepared by the Italian physician Antonio Nardo Recchi. Many years later, other scientific academies arose, such as the "Accademia del Cimento", established in 1657 in Florence and inspired by Galilean thought. In 1662, the "Royal Society" of London, was formally recognized, following Bacon's empirical line, and in 1666 the "Académie Royale des Sciences" was created in Paris, which followed the mechanicist orientation of Descartes. These scientific societies aspired to become centers of information and exchange ideas. Therefore, the "Philosophical Transactions" in London and the "Journal des Savants" in Paris began to be published in 1665. Both publications often included medical articles and notes. Regarding New Spain, the worthy "Academia médico-quirúrgica" of Puebla, mentioned since 1802, must be considered. In independent Mexico, two successive medical academies were established that paved the way for our National Academy of Medicine (1864). This society, since its birth, has been publishing the "Gaceta Médica de México", dean of the Mexican medical journals. PMID:12872422

    In this commentary, we try to make clearer the state of the art concerning the relation between mechanical contact interactions and the different notions of stresses. We emphasize the importance of the concept of virtual displacements. Its role has been recognized in Mechanics and in Continuum Mechanics long ago (see e.g., Vailati in Il principio dei lavori virtuali da Aristotele a Erone d'Alessandria, 113-128, 1987; Russo in The forgotten revolution, Springer, Berlin, 2003, or Cosserat and Cosserat in Sur la Théorie des Corps Déformables, Herman, Paris, 1909; Cosserat and Cosserat in Note sur la théorie de l.action euclidienne, Gauthier-Villars, Paris, 1908), and it is central as well when starting with an expression of the power expended by internal stresses and deducing the form of contact interactions as when starting with some form of the contact interactions and developing a representation theorem for these contact interactions based on the Cauchy tetrahedron construction.

    The effect on the ionosphere of solar eclipse of March 20, 2015 on different ionospheric layers has been studied, using the vertical ionospheric soundings from the ionosondes of Rome, Gibilmanna and San Vito dei Normanni. The response of the critical frequencies foF1 and foF2 have been investigated during the solar eclipse. The DuCharme and Petrie's formulation used to estimate foF1 has been corrected taking into account the decreased solar irradiance. This effect has been modeled by a Solar Obscuration Factor (SOF) and comparison with experimental values has been performed. A further study on the occurrence of the Sporadic E layer during the eclipse is here presented. As reported in literature, sporadic E layer appears during the eclipse, if the ionograms for 3 days before and 3 days after are analysed. When a wider set of days before and after the eclipse event are taken into account this phenomenon does not appear so clear. The behaviour of a regional adaptive and assimilative 3D ionospheric model has been tested as well, assimilating plasma frequency profiles fp(h). The study of the model behaviour in such particular condition has let us introduce corrections to F1 and E region modeling, improving its performances.

    In this paper, we propose a new method for improving the performance of 2D descriptors by building an n-layer image using different preprocessing approaches from which multilayer descriptors are extracted and used as feature vectors for training a Support Vector Machine. The different preprocessing approaches are used to build different n-layer images (n=3, n=5, etc.). We test both color and gray-level images, two well-known texture descriptors (Local Phase Quantization and Local Binary Pattern), and three of their variants suited for n-layer images (Volume Local Phase Quantization, Local Phase Quantization Three-Orthogonal-Planes, and Volume Local Binary Patterns). Our results show that multilayers and texture descriptors can be combined to outperform the standard single-layer approaches. Experiments on 10 datasets demonstrate the generalizability of the proposed descriptors. Most of these datasets are medical, but in each case the images are very different. Two datasets are completely unrelated to medicine and are included to demonstrate the discriminative power of the proposed descriptors across very different image recognition tasks. A MATLAB version of the complete system developed in this paper will be made available at https://www.dei.unipd.it/node/2357. PMID:26656952

    Settling velocities of 58 well-preserved tests of fossil Nummulites were experimentally determined using a settling tube. The tests were collected from the nummulite banks of Pederiva di Grancona (A forms of N. lyelli and N. striatus, Middle Eocene) and San Germano dei Berici (A and B forms of N. fabianii, Late Eocene), both in the Berici Mts. (Veneto, northern Italy). The data were compared with estimated settling velocities that the same specimens might have had in life conditions. This was done by reconstructing their densities simulating water-filled condition and, to simulate post-diagenetic effects, under calcite-filled condition. These simulations show that A and B forms, even if they greatly diverge in shape, volume and size, still possess comparable settling velocities, and that each nummulite bank is characterized by specific hydrodynamic parameters. The use of settling velocity as a parameter to quantify the hydrodynamic behaviour of particles in seawater enables estimation of palaeoenvironmental conditions such as depth, substrate and the energy scenario. Such information is useful in obtaining further insights into the genesis of nummulite banks, the autochthony or allochthony of which is still being debated. Our results point to an autochthonous interpretation. PMID:26681827

    The present study aims to demonstrate the usefulness of GIS to support archive searches and historical studies (e.g. related to industrial archaeology), in the case of an ancient channel for mill powering near Cesena (Emilia-Romagna, Italy), whose history is weaved together with the history of the Compagnia dei Molini di Cesena mill company, the most ancient limited company in Italy. Several historical maps (about 40 sheets in total) inherent the studied area and 80 archive documents (drawings, photos, specifications, administrative acts, newspaper articles), over a period of more than 600 years, were collected. Once digitized, historical maps were analysed, georeferenced and mosaicked where necessary. Subsequently, in all the maps the channel with its four mills and the Savio river were vectorized. All the additional archive documents were digitized, catalogued and stored. Using the QGIS open source platform, a Historical GIS was created, encompassing the current cartographic base and all historical maps, with their vectorized elements; each archive document was linked to the proper historical map, so that the document can be immediately retrieved and visualized. In such a HGIS, the maps form the base for a spatial and temporal navigation, facilitated by a specific interface; the external documents linked to them complete the description of the represented elements. This simple and interactive tool offers a new approach to archive searches, as it allows reconstruction in space and time of the evolution of the ancient channel and the history of this important mill company.

    Licensing and regulation of commercial low-level waste (CLLW) burial facilities require that anticipated risks associated with burial sites be evaluated for the life of the facility. This work reviewed the existing capability to evaluate dose to man resulting from the potential redistribution of buried radionuclides by plants and animals that we have termed biotic transport. Through biotic transport, radionuclides can be moved to locations where they can enter exposure pathways to man. We found that predictive models currently in use did not address the long-term risks resulting from the cumulative transport of radionuclides. Although reports in the literature confirm that biotic transport phenomena are common, assessments routinely ignore the associated risks or dismiss them as insignificant without quantitative evaluation. To determine the potential impacts of biotic transport, we made order-of-magnitude estimates of the dose to man for biotic transport processes at reference arid and humid CLLW disposal sites. Estimated doses to site residents after assumed loss of institutional control were comparable to dose estimates for the intruder-agricultural scenario defined in the DEIS for 10 CFR 61 (NRC). The reported lack of potential importance of biotic transport at low-level waste sites in earlier assessment studies is not confirmed by order of magnitude estimates presented in this study. 17 references, 10 figures, 8 tables.

    The purpose of the work reported here was to develop an order-of-magnitude estimate for the potential dose to man resulting from biotic transport mechanisms at a humid reference low-level waste site in the eastern US. A description of the reference site is presented that includes the waste inventories, site characteristics and biological communites. Parameter values for biotic transport processes are based on data reported in current literature. Transport and exposure scenarios are developed for assessing biotic transport during 500 years following site closure. Calculations of radionuclide decay and waste container decomposition are made to estimate the quantities available for biotic transport. Doses to man are calculated for the biological transport of radionucludes at the reference site after loss of institutional control. These dose estimates are compared to dose estimates we calculated for the intruder-agricultural scenarios reported in the DEIS for 10 CFR 61 (NRC). Dose to man estimates as a result of cumulative biotic transport are calculated to be of the same order-of-magnitude as the dose resulting from the more commonly evaluated human intrusion scenario. The reported lack of potential importance of biotic transport at low-level waste sites in earlier assessment studies is not confirmed by findings presented in this report. Through biotic transport, radionuclides can be moved to locations where they can enter exposure pathways to man.

    In recent decades, a profound conceptual transformation has occurred comprising different areas of biological research, leading to a novel understanding of life processes as much more dynamic and changeable. Discoveries in plants and animals, as well as novel experimental approaches, have prompted the research community to reconsider established concepts and paradigms. This development was taken as an incentive to organise a workshop in May 2014 at the Academia Nazionale dei Lincei in Rome. There, experts on epigenetics, regeneration, neuroplasticity, and computational biology, using different animal and plant models, presented their insights on important aspects of a dynamic architecture of life, which comprises all organisational levels of the organism. Their work demonstrates that a dynamic nature of life persists during the entire existence of the organism and permits animals and plants not only to fine-tune their response to particular environmental demands during development, but underlies their continuous capacity to do so. Here, a synthesis of the different findings and their relevance for biological thinking is presented. PMID:26949518

    New geological mapping has led to a new interpretation of the large-scale superimposed folding in the upper part of the Ivrea-Verbano zone, Italian Alps. The region is widely held to represent an upended section through lower continental crust of northern Italy. The dominant fold structure, extending some 40 km along strike, is the Massone tight to isoclinal antiform, with a hinge line strongly curved through 115°. This folds pre-existing large-scale folds that formed during regional migmatization, probably during the Hercynian orogeny, to form a type-2 interference geometry. The region then suffered post-orogenic mafic magmatic underplating and other magmatism, accompanied by crustal stretching, with contact metamorphism and migmatization causing the imposition of the final pattern of metamorphic isograds. The Ivrea-Verbano zone was brought into contact with the overlying metamorphic rocks of the Serie dei Laghi on a major shear zone. Sub-solidus stretching continued though displacements on low-angle, high-temperature shear zones. Most of the Ivrea-Verbano zone was finally tilted to the vertical and emplaced into its present position after the Mesozoic era and probably during Alpine orogenesis, forming the vertical limb of a crustal-scale double kink.

    The first observation of micro papillary (MP) breast cancer by x-ray dark-field imaging (XDFI) and the first observation of the 3D x-ray internal structure of another breast cancer, ductal carcinoma in-situ (DCIS), are reported. The specimen size for the sheet-shaped MP was 26 mm x 22 mm x 2.8 mm, and that for the rod-shaped DCIS was 3.6 mm in diameter and 4.7 mm in height. The experiment was performed at the Photon Factory, KEK: High Energy Accelerator Research Organization. We achieved a high-contrast x-ray image by adopting a thickness-controlled transmission-type angular analyzer that allows only refraction components from the object for 2D imaging. This provides a high-contrast image of cancer-cell nests, cancer cells and stroma. For x-ray 3D imaging, a new algorithm due to the refraction for x-ray CT was created. The angular information was acquired by x-ray optics diffraction-enhanced imaging (DEI). The number of data was 900 for each reconstruction. A reconstructed CT image may include ductus lactiferi, micro calcification and the breast gland. This modality has the possibility to open up a new clinical and pathological diagnosis using x-ray, offering more precise inspection and detection of early signs of breast cancer.

    BPA and Puget Sound Power and Light (Puget Power) are proposing to upgrade the existing electric transmission power system in the Whatcom and Skagit County area of northwest Washington to increase the capacity of the US-Canada Intertie transmission system. The project would satisfy the need to provide more ability to store and return energy with Canada, would provide additional capacity on the Intertie for anticipated increases in power transactions, and would increase flexibility in operation of the US and Canadian hydroelectric system. It would protect Puget Power`s local system against thermal overloads, and improve local reliability. In November 1993, Bonneville Power Administration (BPA), and Whatcom County (Washington) published a draft environmental impact statement (DEIS) for the proposed Northwest Washington Transmission Project. In order to present some shifts in need for the project and to permit additional review, BPA and Whatcom County have elected to issue a Supplemental Draft EIS. This Summary presents background material, explains project needs and purposes, and then focuses on alternatives and the possible effects.

    In May 1960, the Farmitalia CEO Dr. Bertini and the director of the Istituto Nazionale dei Tumori of Milan Prof. Bucalossi (talent scout and city's Mayor) signed a research agreement for the discovery and development up to clinical trials of new natural antitumor agents. This agreement can be considered as a pioneering and fruitful example of a translational discovery program with relevant transatlantic connections. Owing to an eclectic Streptomyces, found near Castel del Monte (Apulia), and to the skilled and motivated participants of both institutions, a new natural antitumor drug, daunomycin, was ready for clinical trials within 3 years. Patent interference by the Farmitalia French partner was overcome by the good quality of the Italian drug and by the cooperation between Prof. Di Marco, director of the Istituto Ricerche Farmitalia Research Laboratories for Microbiology and Chemotherapy, and Prof. Karnofsky, head of the Sloan-Kettering Cancer Institute of New York, leading to the first transatlantic clinical trials. The search for daunomycin's sister anthracyclines led to the discovery and development of adriamycin, one of the best drugs born in Milan. This was the second act prologue of the history of Italian antitumor discovery and clinical oncology, which started in July 1969 when Prof. Di Marco sent Prof. Bonadonna the first vials of adriamycin (doxorubicin) to be tested in clinical trials. This article reviews the Milan scene in the 1960s, a city admired and noted for the outstanding scientific achievements of its private and public institutions in drugs and industrial product discovery.

    We focus on the period of ~ 9 - 5 Ma when an episode of notably cool temperatures corresponds to evidence of high latitude Northern Hemisphere glaciation and mid-latitude terrestrial evolution. Alkenone-based sea surface temperatures (SST) from six globally distributed sites: ODP Sites 907 and 982 in the North Atlantic, ODP Site 1088 in the South Atlantic and ODP Sites 883, 884 and 887 in the North Pacific, and the Monte dei Corvi marine section in the Mediterranean unequivocally establish a dramatic, Late Miocene cold episode that persisted over approximately 2.5 Myr. In this work we establish the timing and synchronization of temperature decrease as well as rebound at orbital timescales. All sites were notably warmer than their modern annual average at ~9 Ma and exhibit sustained cooling beginning at ~8 Ma. SSTs rebound close to ~5.9 Ma at most locations suggesting that the cooling trend that began in the Late Miocene slowed down or even reversed in some locations in the Pliocene. The newly reconstructed SSTs highlight the role of cooling and an increase in equator to pole temperature gradients in terrestrial evolution at this pivotal time.

    On 2013 March 21, high-resolution slit spectrographs of the comet C/2011 L4 (Panstarrs), at a heliocentric distance r = 0.46 AU, were obtained at the Osservatorio Astronomico Campo dei Fiori, Italy. Emission lines of sodium were the strongest in the spectrum as is common in comets, but potassium lines were also detected. These have rarely been observed in comets since the apparition of the brightest comet C/1965 S1 (Ikeya-Seki). Lithium was not detected and stringent upper limits of its abundance compared to other alkali were derived. We obtain the abundance ratios Na/K = 54 {+-} 14 and Na/Li {>=}810{sup 3}. In addition to Mercury's exosphere (Leblanc and Doressoundiram), we show that photoionization at the beginning of the alkali tails may increase the solar ratio Na/K = 15.5 (Asplund et al.) by a factor three, close to that required to match the observed value. In the same tail position, the Na/Li ratio increases only by a factor two, very far from the factor {>=}8 required to match an original meteoritic ratio. We apply the same model to similar alkali data (Preston) of the comet C/1965 S1 (Ikeya-Seki) and obtain consistent results. An original solar Na/K ratio fits the observed value at the beginning of the alkali tails within the slit size, whereas Li is depleted by a factor {>=}8.

    DAISY (Differential Algebra for Identifiability of SYstems) is a recently developed computer algebra software tool which can be used to automatically check global identifiability of (linear and) nonlinear dynamic models described by differential equations involving polynomial or rational functions. Global identifiability is a fundamental prerequisite for model identification which is important not only for biological or medical systems but also for many physical and engineering systems derived from first principles. Lack of identifiability implies that the parameter estimation techniques may not fail but any obtained numerical estimates will be meaningless. The software does not require understanding of the underlying mathematical principles and can be used by researchers in applied fields with a minimum of mathematical background. We illustrate the DAISY software by checking the a priori global identifiability of two benchmark nonlinear models taken from the literature. The analysis of these two examples includes comparison with other methods and demonstrates how identifiability analysis is simplified by this tool. Thus we illustrate the identifiability analysis of other two examples, by including discussion of some specific aspects related to the role of observability and knowledge of initial conditions in testing identifiability and to the computational complexity of the software. The main focus of this paper is not on the description of the mathematical background of the algorithm, which has been presented elsewhere, but on illustrating its use and on some of its more interesting features.

This magnificent collection contains an impressive amount of treatises by Greek philosophers and, especially, Philodemus of Gadara, an Epicurean thinker of 1st century BC. We read many portions of text hidden inside carbonized Herculaneum papyri using enhanced X-ray phase-contrast tomography non-destructive technique and a new set of numerical algorithms for ‘virtual-unrolling’. Our success lies in revealing the largest portion of Greek text ever detected so far inside unopened scrolls, with unprecedented spatial resolution and contrast, all without damaging these precious historical manuscripts. Parts of text have been decoded and the ‘voice’ of the Epicurean philosopher Philodemus is brought back again after 2000 years from Herculaneum papyri. PMID:27265417

    The beauty of cultural heritage and monumental architecture, is often linked to their non-structural elements and decorative stones façades cladding. The collapse of these elements causes significant consequences that interest the social, the economic, the historical and the technical fields. Several regulatory documents and literature studies contain methods to address the question of relief and of the risk analysis and due to the non - structural stones security. Among the references are widespread international regulatory documents prepared by the Federal Emergency Management Agency of the United States by Applied Technology Council and California. In Italy there are some indications contained in the Norme Tecniche per le Costruzioni and the Direttiva del Presidente del Consiglio dei Ministri in 2007, finalize to the reduction of seismic risk assessment of cultural heritage. The paper, using normative references and scientific researches, allows to analyze on Royal Palace of Caserta the safety and the preservation of cultural heritage and the vulnerability of non-structural stones façade cladding. Using sophisticated equipments of Laboratory ARS of the Second University of Naples, it was possible to analyze the collapse of stone elements due to degradation caused by natural phenomena of deterioration (age of the building, type of materials, geometries , mode of fixing of the elements themselves). The paper explains the collapse mechanisms of stones façade cladding of Luigi Vanvitelli Palace.

    The first observation of micro papillary (MP) breast cancer by x-ray dark-field imaging (XDFI) and the first observation of the 3D x-ray internal structure of another breast cancer, ductal carcinoma in-situ (DCIS), are reported. The specimen size for the sheet-shaped MP was 26 mm × 22 mm × 2.8 mm, and that for the rod-shaped DCIS was 3.6 mm in diameter and 4.7 mm in height. The experiment was performed at the Photon Factory, KEK: High Energy Accelerator Research Organization. We achieved a high-contrast x-ray image by adopting a thickness-controlled transmission-type angular analyzer that allows only refraction components from the object for 2D imaging. This provides a high-contrast image of cancer-cell nests, cancer cells and stroma. For x-ray 3D imaging, a new algorithm due to the refraction for x-ray CT was created. The angular information was acquired by x-ray optics diffraction-enhanced imaging (DEI). The number of data was 900 for each reconstruction. A reconstructed CT image may include ductus lactiferi, micro calcification and the breast gland. This modality has the possibility to open up a new clinical and pathological diagnosis using x-ray, offering more precise inspection and detection of early signs of breast cancer.

    In this paper we propose an ensemble of texture descriptors for analyzing virus textures in transmission electron microscopy images. Specifically, we present several novel multi-quinary (MQ) codings of local binary pattern (LBP) variants: the MQ version of the dense LBP, the MQ version of the rotation invariant co-occurrence among adjacent LBPs, and the MQ version of the LBP histogram Fourier. To reduce computation time as well as to improve performance, a feature selection approach is utilized to select the thresholds used in the MQ approaches. In addition, we propose new variants of descriptors where two histograms, instead of the standard one histogram, are produced for each descriptor. The two histograms (one for edge pixels and the other for non-edge pixels) are calculated for training two different SVMs, whose results are then combined by sum rule. We show that a bag of features approach works well with this problem. Our experiments, using a publicly available dataset of 1500 images with 15 classes and same protocol as in previous works, demonstrate the superiority of our new proposed ensemble of texture descriptors. The MATLAB code of our approach is available at https://www.dei.unipd.it/node/2357. PMID:25488214

    We have evidence for decreasing galactic cosmic ray (GCR) flux in the past 3 centuries by a factor about two [1]. The measurements of the activity of cosmogenic 44Ti (T1/2 = 59.2 y) produced by GCR in stony meteorites that fell during the last two centuries are in good agreement with the calculated values and validate the decreasing trend of GCR flux. The measurements were obtained by an hyperpure (372 cm3) Ge-NaI(Tl) spectrometer operating in the Monte dei Cappuccini laboratory in Torino[2]. To further improve upon statistical precision of 44Ti data and also to be able to measure the 42Ar (T1/2 = 33 y) which is produced in even smaller amounts by GCR in meteorites, we have set up in the same laboratory a larger (581 cm3) hyperpure Ge detector operating in coincidence with a 100 kg NaI(Tl) crystal assembly. This should enable us to confirm the above results about GCR variations. We wish to acknowledge our deep gratitude to professor Bonino, deceased on September 29, 2002, to whom the assemblage of the new equipment is due. [1] G. Bonino, G. Cini Castagnoli, D. Cane, C.

    Canine distemper virus (CDV) infection is a primary threat affecting a wide number of carnivore species, including wild animals. In January 2013, two carcasses of Apennine wolves (Canis lupus) were collected in Ortona dei Marsi (L'Aquila province, Italy) by the local Veterinary Services. CDV was immediately identified either by RT-PCR or immunohistochemistry in lung and central nervous tissue samples. At the same time, severe clinical signs consistent with CDV infection were identified and taped (Videos S1–S3) from three wolves rescued in the areas surrounding the National Parks of the Abruzzi region by the Veterinary Services. The samples collected from these symptomatic animals also turned out CDV positive by RT-PCR. So far, 30 carcasses of wolves were screened and CDV was detected in 20 of them. The sequencing of the haemagglutinin gene and subsequent phylogenetic analysis demonstrated that the identified virus belonged to the CDV Arctic lineage. Strains belonging to this lineage are known to circulate in Italy and in Eastern Europe amongst domestic dogs. To the best of our knowledge this is the first report of CDV Arctic lineage epidemics in the wild population in Europe. PMID:24465373

    An electronic nose and an UV-Vis spectrophotometer, in combination with multivariate analysis, have been used to verify the geographical origin of extra virgin olive oils. Forty-six oil samples from three different areas of Liguria were included in this analysis. Initially, the data obtained from the two instruments were analysed separately. Then, the potential of the synergy between these two technologies for testing food authenticity and quality was investigated. Application of Linear Discriminant Analysis, after feature selection, was sufficient to differentiate the three geographical denominations of Liguria ("Riviera dei Fiori", "Riviera del Ponente Savonese" and "Riviera di Levante"), obtaining 100% success in classification and close to 100% in prediction. The models built using SIMCA as a class-modelling tool, were not so effective, but confirmed that the results improve using the synergy between different analytical techniques. This paper shows that objective instrumental data related to two important organoleptic features such as oil colour and aroma, supply complementary information. PMID:17397658

    Istituto Scientifico Romagnolo per lo Studio e la Cura dei Tumori (IRST) IRCCS is a public-private partnership among 3 public sector bodies and 6 private nonprofit organizations and represents the hub of the Oncology Network of Romagna, which provides a wide range of services for the population ranging from primary prevention to palliative care. In 2012, IRST took part in the ministerial research project of the Organisation of European Cancer Institutes (OECI) accreditation program for Comprehensive Cancer Centers. The self-assessment period lasted 6 months and was coordinated by a multidisciplinary project team headed by a project leader. Each project team member coordinated a subgroup whose task was to analyze specific standards from qualitative and quantitative questionnaires. During the self-assessment period for the areas in which IRST did not meet OECI requirements, the project team outlined several improvement plans. At the end of the self-assessment period, the OECI Accreditation & Designation Board approved the documentation presented by IRST and a peer review visit was scheduled. The OECI report suggested establishing a more specific and stronger centralized management and leadership of all the oncologic activities carried out in other centers. In accordance with these suggestions, IRST and the Local Health Authority of Romagna laid the foundations for a new management model for the Oncology Network of Romagna: the Comprehensive Cancer Care Network (CCCN). The CCCN is a territory-oriented model (population approach) based on a principle of cooperation and collaboration among the network nodes. PMID:27096275

    Enhanced contrast X-ray imaging is achieved by exploiting the real part of the refraction index, which is responsible for the phase shifts, in addition to the imaginary part, which is responsible for the absorption. Such techniques are called X-ray phase contrast imaging. An analyzer-based X-ray phase contrast imaging set-up with Diffraction Enhanced Imaging processing (DEI) were used for preliminary studies in anatomy and embryology of insects. Parasitized stinkbug and moth eggs used as control agents of pests in vegetables and adult stinkbugs and mosquitoes ( Aedes aegypti) were used as samples. The experimental setup was mounted in the SYRMEP beamline at ELETTRA. Images were obtained using a high spatial resolution CCD detector (pixel size 14×14 μm 2) coupled with magnifying optics. Analyzer-based X-ray phase contrast images (PCI) and edge detection images show contrast and details not observed with conventional synchrotron radiography and open the possibility for future study in the embryonic development of insects.

  4. Aftershocks hazard in Italy Part I: Estimation of time-magnitude distribution model parameters and computation of probabilities of occurrence

    We analyzed the available instrumental data on Italian earthquakes from1960 to 1996 to compute the parameters of the time-magnitudedistribution model proposed by Reasenberg and Jones (1989) andcurrently used to make aftershock forecasting in California. From 1981 to1996 we used the recently released Catalogo Strumentale deiTerremoti `Italiani' (CSTI) (Instrumental Catalog Working Group, 2001)joining the data of the Istituto Nazionale di Geofisica e Vulcanologia(INGV) and of the Italian major local seismic network, with magnituderevalued according to Gasperini (2001). From 1960 to 1980 we usedinstead the Progetto Finalizzato Geodinamica (PFG) catalog(Postpischl, 1985) with magnitude corrected to be homogeneous with thefollowing period. About 40 sequences are detected using two differentalgorithms and the results of the modeling for the corresponding ones arecompared. The average values of distribution parameters (p= 0.93±0.21, Log10(c) = -1.53±0.54, b = 0.96±0.18 and a = -1.66±0.72) are in fair agreementwith similar computations performed in other regions of the World. We alsoanalyzed the spatial variation of model parameters that can be used topredict the sequence behavior in the first days of future Italian seismic crisis,before a reliable modeling of the ongoing sequence is available. Moreoversome nomograms to expeditiously estimate probabilities and rates ofaftershock in Italy are also computed.

    In this paper, we investigate the possibility of computing quantitatively accurate images of mass density variations in soft tissue. This is a challenging task, because density variations in soft tissue, such as the breast, can be very subtle. Beginning from an image of refraction angle created by either diffraction-enhanced imaging (DEI) or multiple-image radiography (MIR), we estimate the mass-density image using a constrained least squares (CLS) method. The CLS algorithm yields accurate density estimates while effectively suppressing noise. Our method improves on an analytical method proposed by Hasnah et al (2005 Med. Phys. 32 549-52), which can produce significant artifacts when even a modest level of noise is present. We present a quantitative evaluation study to determine the accuracy with which mass density can be determined in the presence of noise. Based on computer simulations, we find that the mass-density estimation error can be as low as a few per cent for typical density variations found in the breast. Example images computed from less-noisy real data are also shown to illustrate the feasibility of the technique. We anticipate that density imaging may have application in assessment of water content of cartilage resulting from osteoarthritis, in evaluation of bone density, and in mammographic interpretation.

    Lapis-lazuli is a semi-precious stone used in the past to produce a blue pigment. Its main component is lazurite, 3Na 2O·3Al 2O 3·6SiO 2·2Na 2S. The possibility of using PIXE to identify this pigment in canvas and wood painting is severely limited by the strong absorption of low-energy X-rays in the protective varnish and - when, as typical, the pigment is mixed with lead white - by the overlapping of Pb M lines with S K α. In this work we discuss the possibility of identifying lapis-lazuli by detecting sodium with PIGE. PIXE and PIGE measurements have been performed on samples containing lapis-lazuli mixed to lead white in different percentage, covered with polymeric foils to simulate the presence of varnish. At a percentage of lapis-lazuli below 50%, Na X-rays are hardly detectable even with the thinner foil; on the contrary the characteristic γ-rays are clearly detected down to about 1%. A first application has been successfully performed on the "Madonna dei fusi" by Leonardo da Vinci, in the framework of an extensive scientific investigation on the painting techniques used by the Renaissance genius.

    Natural dyes have been used extensively in the past for many purposes, such us to colour fibers and to produce inks, watercolours and paints, but their use declined rapidly after the discovery of synthetic colours. Nowadays we witness a renewed interest, as natural dyes are neither toxic nor polluting. In this work, physical and chemical properties of four selected dyes, namely red (Madder), yellow (Weld and Turmeric) and blue (Woad) colours, produced by means of traditional techniques at the Museo dei Colori Naturali (Lamoli, Italy), have been investigated. The chromatic properties have been studied through the reflectance spectroscopy, a non-invasive technique for the characterisation of chromaticity. Reflection spectra both from powders and egg-yolk tempera models have been acquired to provide the typical features of the dyes in the UV-vis spectral range. Moreover, to assess the feasibility of laser cleaning procedures, tempera layers were investigated after irradiation with an excimer laser. Micro Raman spectroscopy, Scanning Electron Microscopy and Energy Dispersive X-Ray analyses have complemented the survey, returning compositional and morphological information as well. Efforts have been made to give scientific feedback to the production processes and to support the research activity in the restoration of the artworks where these dyes were employed.

    The objective of this study was to evaluate in `Smoothee Golden Delicious' apples, the use of backscattering images as a non-destructive method to estimate some quality parameters during the ripening process of fruits. In this experiment, 208 apples were collected from an experimental orchard of the Estación Experimental de Aula Dei (CSIC) in Zaragoza (Northeastern, Spain). Backscattering images were kept from samples picked up every 15 days during 7 months until harvest. In the same fruits, soluble solids contents (SSC) and firmness were measured by traditional destructive methods. The light source was a solid state laser diode module emitting at three different spectral bands (670, 785 and 980 nm) PLS calibration methods were used to create the statistical model to predict SSC and firmness. Good results were obtained when PLS calibration was applied to Feret diameter corresponding at different levels of gray. The Rcv2 values were 0.87 for firmness and 0.93 for SSC, which are higher than other reported in the literature for the same commodity.

    Hyperglycaemic patients admitted to hospital have worse clinical outcomes with higher operational costs than normoglycaemic patients. Identifying, defining and treating hyperglycaemia promptly and appropriately is essential during hospitalisation; adequate 'continuity of care' must be assured after discharge. This requires a multidisciplinary clinical collaboration between the internist and the diabetes team, which plays a central role in the treatment course and should be involved soon after patient admission to the hospital. This document aims to establish guidelines and recommendations for good clinical practice in managing hyperglycaemic internal medicine patients, with or without previous diagnosis of diabetes. The Associazione Medici Diabetologi (AMD), Federazione delle Associazioni dei Dirigenti Ospedalieri Internisti (FADOI) and Società Italiana di Diabetologia (SID) have decided to publish a document useful for internists in the management of hospitalised patients with hyperglycaemia. The Trialogue project, coordinated by a Board of Scientific Experts from the three scientific societies, was initiated for this purpose. A questionnaire consisting of 16 multiple choice questions on the management of hyperglycaemia in hospital was answered by 660 physicians from over 250 Internal Medicine units distributed throughout Italy. Analysis of responses has yielded an overview of routine clinical practice and provided a wealth of ideas to better identify critical points in the treatment of hospitalised patients with hyperglycaemia. These recommendations were developed with the aim of providing mutually agreed practical guidance (instructions for use) that can be readily applied by healthcare professionals in routine clinical practice.

    The medical imaging facility of the ESRF is devoted to human coronary angiography, computed tomography, diffraction enhanced imaging (DEI), bronchography, and also radiation therapy programs. Most of the imaging is performed in a satellite building located at 150 m from the wiggler source (H. Elleaume et al., Nucl. Instr. and Meth. A 428 (1999) 513). A multi-purpose device known as the Patient Positioning System (PPS or medical chair) has been designed to perform in different modes of research on patients. This device operates in the angiography mode, with alternating up and down movements in 1.6 s cycles over a period of about 30 s. The tomography mode is used mainly for the imaging of the brain. It consists of turning the patient around an axis perfectly perpendicular to the beam plane. A dual-energy scan involves two rotations with one image recorded each turn at a different energy (Phys. Med. Biol. 45 (2000) L39). The first angiography imaging on patients was undertaken in January 2000 after successful pre-clinical tests on animals.

    2015-01-01

    Famed for his collection of drawings of naturalia and his thoughts on the relationship between painting and natural knowledge, it now appears that the Bolognese naturalist Ulisse Aldrovandi (1522-1605) also pondered specifically color and pigments, compiling not only lists and diagrams of color terms but also a full-length unpublished manuscript entitled De coloribus or Trattato dei colori. Introducing these writings for the first time, this article portrays a scholar not so much interested in the materiality of pigment production, as in the cultural history of hues. It argues that these writings constituted an effort to build a language of color, in the sense both of a standard nomenclature of hues and of a lexicon, a dictionary of their denotations and connotations as documented in the literature of ancients and moderns. This language would serve the naturalist in his artistic patronage and his natural historical studies, where color was considered one of the most reliable signs for the correct identification of specimens, and a guarantee of accuracy in their illustration. Far from being an exception, Aldrovandi's 'color sensibility'spoke of that of his university-educated nature-loving peers. PMID:26856048

    Since the creation of the National Environmental Policy Act in 1970, the United States has required the Environmental Protection Agency (EPA) to rate draft environmental statements (DEISs) for both information adequacy and the impact of the preferred alternative on the environment. In a previous study by Tzoumis and Finegold (2000), these ratings were found to be declining from 1970 to 1997. This current study investigates if that trend continued from 1998 to 2004. In addition, the top producing agencies (the Forest Service, the Federal Highway Administration, Army Corp of Engineers, and the Bureau of Land Management) are compared for the achievement of DEIS ratings. The results show that when the ratings are disaggregated for these agencies, the results indicate that there continues to be weak performance. The DEISs continue to have insufficient and sometimes inadequate information. Agencies continue to propose projects that have environmental concerns and sometimes objections. The agencies have some similarities in not being able to achieve the highest ratings on a consistent basis over time. However, more disturbing is the profile of agencies that have episodic peaks of achieving the lowest ratings. Conclusions and recommendations are focused on the agencies who submit that DEISs and EPA. One major conclusion is to better track the ratings and make them collectively available for the public. Agencies are encouraged to develop a best management practice in preparing DEISs to promote agency learning.

    The earliest activity of Monte Vulture, central Italy, included ignimbrites but the bulk of the volcano was built up by plinian airfall deposits. Contemporaneous remobilisation of these deposits formed an apron of lahars around the base of the main cone. The volcano was constructed on a ridge; the valley to the east and tributaries to the north and south became sediment traps for volcaniclastic materials emplaced by fluvial reworking and directly from volcanic activity. To the west the valley was swept clear by active downcutting. Instability of the west flank as a result of this erosion was probably a contributory cause of major gravitational sector collapse on the volcano's flank, terminating the main cone-building phase. The resultant scar is an amphitheatre-shaped hollow called here the Valle dei Grigi. Previous workers have attributed this feature to coalescing calderas formed by engulfment. The last volcanic phase was the production of the Monticchio calderas and associated phreatomagmatic explosions producing airfall and surge deposits. Because most of the activity at Vulture has been repeated plinian eruptions producing similar assemblages of products, detailed stratigraphy of the volcano is difficult to accomplish. To characterise Vulture in terms of its products, various facies are identified and interpreted in relation to volcanic processes, distance from vent and environmental conditions.

    Two innovative laser scanning prototypes have been developed at ENEA for diagnostics of large surfaces relevant to monumental cultural heritage. The first, based on amplitude modulation technique in the visible, is a trichromatic (Red /Green /Blue) imaging topologic radar (RGB-ITR) specialized to collect high resolution 3D models. After proper color calibration, it allows for hyper-realistic rendering of colored features on painted surfaces and for precise localization of irregularities. The second is a line scanning system, working either in reflectance or laser induced fluorescence mode, capable of fast 2D monochromatic images acquisition on up to 90 different spectral channels in the visible/UV range, which was developed to investigate the presence of different substances onto the painted surface. Data collected during former field campaigns on frescos by means each scanning system will be reported and discussed extracting information of interest to conservators by means of specific data processing methodologies and respective software tools. Recent results relevant to paints of the Assumption on slate and canvas by Scipione Pulzone named "il Gaetano" collected in two churches in Rome (San Silvestro al Quirinale, Bandini chapel; Santa Caterina dei Funari, Solano della Vetera Chapel) from the late XVI century are presented in order to demonstrate the increased diagnostic capabilities coming from data integration. From combination of reflectance data from both instruments, the first true remote differential colorimetry has been implemented, giving a chance to test the color quality in the future from the archived images.

    Color and color infrared aerial photography and imagery acquired from a Daedalus DEI-1260 multispectral airborne scanner were employed in an investigation to discriminate ultramafic rock types in a test site in southwest Oregon. An analysis of the relationships between vegetation characteristics and parent materials was performed using a vegetation classification and map developed for the project, lithologic information derived from published geologic maps of the region, and terrain information gathered in the field. Several analytical methods, including visual image analysis, band ratioing, principal components analysis, and contrast enhancement and subsequent color composite generation were used in the investigation. There was a close correspondence between vegetation types and major rock types. These were readily discriminated by the remote sensing techniques. It was found that ultramafic rock types were separable from non-ultramafic rock types and serpentine was distinguishable from non-serpentinized peridotite. Further investigations involving spectroradiometric and digital classification techniques are being performed to further identify rock types and to discriminate chromium and nickel-bearing rock types.

    Over the last decade new technologies are emerging even more for wastewater treatment. Among the new technologies, a recent possible solution regards Moving Bed Biofilm Reactors (MBBRs) that represent an effective alternative to conventional processes. More specifically such systems consist in the introduction of plastic elements inside the aerobic reactor as carrier material for the growth of attached biomass. Recently, one of the mostly used alternatives is to couple the Moving Bed Biofilm Reactor (MBBR) process with the conventional activated sludge process, and the resulting process is usually called HMBBR (Hybrid MBBR). In the MBBR process the biofilm grows attached on small plastic elements that are kept in constant motion throughout the entire volume of the reactor. Indeed, in such a system, a competition between the two biomasses, suspended and attached, can arise for the availability of the substrates, leading, as a consequence, to a modification in the biokinetic parameters of the two biomasses, compared to that of a pure suspended or attached biomass process. This paper presents the first results of a study aimed at estimating the kinetic heterotrophic constants in a HMBBR pilot plant using respirometric techniques. The pilot plant was built at the Acqua dei Corsari (Palermo) wastewater treatment plant and consisted of two parallel lines realized in a pre-anoxic scheme, in one of which the carrier material was added to the aerobic reactor with a filling ratio of 30%.

  18. Draft environmental impact statement for the Galileo Mission (Tier 2)

    NASA Technical Reports Server (NTRS)

    1988-01-01

    This Draft Environmental Impact Statement (DEIS) addresses the environmental impacts which may be caused by the preparation and operation of the Galileo spacecraft, including its planned launch on the Space Transportation System (STS) Shuttle and the alternative of canceling further work on the mission. The launch configuration will use the STS/Inertial Upper Stage (IUS)/Payload Assist Module-Special (PAM-S) combination. The Tier 1 EIS included a delay alternative which considered the Titan 4 launch vehicle as an alternative booster stage for launch in 1991 or later. However, the U.S. Air Force, which procures the Titan 4 for NASA, could not provide a Titan 4 vehicle for the 1991 launch opportunity because of high priority Department of Defense requirements. The only expected environmental effects of the proposed action are associated with normal Shuttle launch operations. These impacts are limited largely to the near-field at the launch pad, except for temporary stratospheric ozone effects during launch and occasional sonic boom effects near the landing site. These effects have been judged insufficient to preclude Shuttle launches. In the event of: (1) an accident during launch, or (2) reentry of the spacecraft from earth orbit, there are potential adverse health and environmental effects associated with the possible release of plutonium dioxide from the spacecraft's radioisotope thermoelectric generators (RTG).

    Primary melanomas (M) of the rectum and anal canal are a rare pathological event, constituting approximately 1% of all invasive tumors in this site. From January 1973 to December 1990 at the Istituto Nazionale per lo Studio e 1a Cura dei Tumori of Milan, 11 patients were treated for M (5 males and 6 females), with a mean age of 60 years (range 40-80). The site of origin of the M was rectal in four patients, anal in five patients and in the anorectal joint in two patients. The lesion was prevalently polypoid and the average size was 4 cm (1-7.5 cm). Symptoms referred by the patients were rectal bleeding and tenesmus. In one patient the diagnosis was made after biopsy of an inguinal metastatic lymphnode. Of the 11 patients, six underwent curative resection (four Miles' resections and two local excisions). One patient is still alive with no evidence of disease after 120 months. The remaining five patients were submitted to palliative treatment, due to the presence of metastases in four of them and to age and general conditions in one. All of these patients died at 1, 2, 4, 5, and 6 months (median: 4 months). Overall median survival was eight months: 20 months in the radically treated group and four months in the palliatively treated group. Our data are in agreement with those reported in literature and confirm the prognostic severity of anorectal M due both to late diagnosis and the biological aggressiveness of the neoplasm.

    The purpose of the work reported here was to develop an order of magnitude estimate for the potential dose to man resulting from biotic transport mechanisms at a reference western arid low-level waste site. A description of the reference site is presented that includes the waste inventories, site characteristics and biological communities. Parameter values for biotic transport processes are based on data reported in current literature. Transport and exposure scenarios are developed for assessing biotic transport during 100 years following site closure. Calculations of radionuclide decay and waste container decomposition are made to estimate the quantities available for biotic transport. Dose to a man occupying the reference site following the 100 years of biotic transport are calculated. These dose estimates are compared to dose estimates for the intruder-agricultural scenario reported in the DEIS for 10 CFR 61 (NRC). Dose to man estimates as a result of biotic transport are estimated to be of the same order of magnitude as the dose resulting from the more commonly evaluated human intrusion scenario. The reported lack of potential importance of biotic transport at low-level waste sites in earlier assessment studies is not confirmed by the findings presented in this report. These results indicate that biotic transport has the potential to influence low-level waste site performance. Through biotic transport, radionuclides may be moved to locations where they can enter exposure pathways to man.

    El síndrome de caquexia cancerosa es responsable de la muerte de un número significativo de pacientes con cáncer. Se caracteriza por la presencia de una ingesta reducida, con inflamación sistémica y un metabolismo alterado. Los enfermos presentan característicamente una progresiva pérdida de peso y de masa muscular, junto a deterioro funcional. La pérdida muscular se debe a la combinación de reducción de la síntesis proteica con aumento de su degradación. Ello conduce tanto a un acortamiento como a una reducción en el área de la fibra muscular. Asimismo, existen datos que apoyan que selectivamente algunos de los tipos de fibra muscular se ven más afectados. Es necesario definir bien los valores de corte de sarcopenia para diagnosticar la pérdida muscular y existen diferentes métodos. El sistema de la ubiquitina-proteasoma parece desempeñar un papel predominante en la degradación de la proteína miofibrilar. La tendencia a perder masa muscular en los pacientes con caquexia cancerosa parece estar asociada a la activación de señales catabólicas por citoquinas proinflamatorias, así como por productos tumorales del tipo factor inductor de proteólisis. En referencia a los factores pronósticos, el riesgo de muerte está bien documentado en pacientes con sarcopenia y, especialmente, en aquellos con obesidad asociada a la sarcopenia. Asimismo, se ha establecido una relación directa entre la pérdida intensa de masa muscular y la supervivencia en pacientes con diferentes tipos de tumores del tipo de cáncer de páncreas, pulmón, tracto biliar o cáncer colorrectal. Respecto de la terapia en el síndrome de caquexia cancerosa, es factible que requiera tratamiento con varios grupos combinados que incluyan, junto al soporte nutricional, fármacos orexígenos, con efecto anabólico y antinflamatorio, asociados a intervenciones que estimulen el ejercicio físico.

    Introducción: el tipo de ácido graso de la dieta presenta diferentes efectos sobre la obesidad y sus complicaciones, pero estos efectos pueden verse influenciados por los genes y sus polimorfismos, tales como los receptores activados por el proliferador de los peroxisomas isoforma γ2 (PPARγ2). Además, no está claro si el grado de insaturación de los lípidos posee diferentes efectos en el metabolismo de los lípidos y de la glucosa y, particularmente, en la pérdida de peso. Objetivos: evaluar la influencia de dietas ricas en ácidos grasos poliinsaturados (AGPI) y monoinsaturados (AGMI) en las variables antropométricas y bioquímicas en el peso corporal y el perfil glucémico y lipémico en mujeres obesas con el genotipo Pro12Pro en el gen PPARγ2. Métodos: dieciocho mujeres obesas con genotipo Pro12Pro fueron distribuidas aleatoriamente para una de las dietas, rica en AGPI (n = 8) o AGMI (n = 10). Las variables antropométricas (índice de masa corporal [IMC] y circunferencia de la cintura) y bioquímicas (glucosa, insulina, HOMA-IR, colesterol total, LDL-colesterol, HDL colesterol y triglicéridos) fueron evaluadas antes y después de un periodo de 45 días. Resultados: las variables antropométricas y bioquímicas fueron similares entre los grupos antes y después de la intervención (p > 0,05). El IMC disminuyó después de la ingesta de AGPI (p = 0,01), probablemente debido al menor contenido de lípidos. El AGMI redujo la glucosa (p = 0,03), insulina (p = 0,03) y HOMA-IR (p = 0,02). Conclusión: los AGMI fueron más eficientes para reducir la resistencia a la insulina en mujeres obesas con el genotipo Pro12Pro en el gen PPARγ2, aunque las mujeres presentaran una elevada ingesta de lípidos totales y ácidos grasos saturados.

For the four breach methodologies, a sensitivity analysis of four breach parameters, breach side slope (SS), breach width (Wb), breach invert elevation (Elb), and time of failure (tf), is conducted. Up to, 68 simulations are computed to produce breach hydrographs in HEC-RAS for input into Flood2D-GPU. The Flood2D-GPU simulation results were then post-processed in HEC-FIA to evaluate: Total Population at Risk (PAR), 14-yr and Under PAR (PAR14-), 65-yr and Over PAR (PAR65+), Loss of Life (LOL) and Direct Economic Impact (DEI). The MLM approach resulted in wide variability in simulated minimum and maximum values of PAR, PAR 65+ and LOL estimates. For PAR14- and DEI, Froehlich (1995) resulted in lower values while MLM resulted in higher estimates. This preliminary study demonstrated the relative performance of four commonly used dam breach methodologies and their impacts on consequence estimation.

  6. 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.

    Near-surface geophysics can play a major role in the framework of the Cultural Heritages diagnostics as the recourse to non-invasive geophysical methods is usually the only way to gain information on subsurface properties that can affect the stability of historical structures and accelerate degradation processes. In most cases the deterioration of ancient buildings is due to various causes: external, such as pollution, biological degradation and adverse climatic or microclimatic conditions; internal, such as a particular geological or hydro-geological setting or a combination of both. Therefore, being able to discriminate between the different sources and to identify the main process of decay becomes essential for the development of effective remediation actions. The present case study shows the main results of an integrated geophysical campaign performed inside the cloister of an important palace in Lecce, Southern Italy, in order to investigate the possible subsurface causes of deterioration affecting its pillars and walls and, more importantly, some altars of the annexed church. The historical building, named Palazzo dei Celestini, was formerly a monastery directly connected to the Basilica of Santa Croce and nowadays is the head office of the Province of Lecce Administration and the Prefecture. With its rich baroque façade, Palazzo dei Celestini and Santa Croce is the most famous architectural complex of the historical centre of Lecce. Its foundations generally rest on a very shallow and sometimes outcropping wet calcarenitic basement, evidenced by previous geophysical surveys performed in the nearby. The high capillarity of the local fine-grained calcarenitic stone used as building and ornamental material for the historical complex was thought to be responsible for the deterioration problems evidenced at some altars of the church and in the lower portion of the walls and pillars of the palace, although a previous microclimatic study inside the Basilica had

    The Late Miocene warmer-than-modern Earth is a time of important transitions such as the C3/C4 photosynthesis transition, the appearance of the Sahara and the hominin evolution. The interconnections and drivers for climate and evolutionary change during this time, such as pCO2, albedo, vegetation and temperatures, are still speculative. The causal relationships can be better understood via paleoproxy records from sensitive to climate shifts areas such as the Mediterranean Sea. The Mediterranean Sea is a largely enclosed mid-latitude basin on the cusp of the subtropical climate zone formed after the closure of the Tethys. The enclosed nature of the Mediterranean Sea makes it sensitive to continental climate and shifts in climate zones with the advantage of resolution, preservation and detail usually reserved for marine records Here we present a continuous 30 kyr resolution, sea surface temperature (SST) record for the Mediterranean Sea (Late Miocene - Pliocene) from the well-dated, uplifted marine sequences of Monte dei Corvi in Northern Italy and Rosello in Sicily, Italy. The Late Miocene portion of the record is from the pelagic, uplifted Monte dei Corvi land section. The data from two organic paleothermometers UK'37 and TEX86, establish the Mediterranean Sea as notably warmer than present. SSTs were equivalent and even higher than the warmest parts of the modern ocean. For the oldest samples, ~ 12.9 Ma to ~8.1 Ma, UK'37 derived temperatures hovered close to 28oC and possibly even higher. A distinct cooling trend takes over starting at ~8.1 Ma and superimposed upon it are prominent, high variability, cold episodes lasting from ~7 Ma to 6 Ma. During these extreme episodes, reconstructed SSTs reach values comparable the modern eastern Mediterranean annual average SST of 19.5oC. The variability during this colder period is substantial, with temperature swings of as much as ~6-8 oC over 40 kyr. Continuous pelagic sedimentation resumes after the Messinian Salinity

    Within the framework of the VIGOR project, a characterization of medium enthalpy geothermal resources have been carried out in the Campania region (southern Italy), with a focus on the "Guardia dei Lombardi" area (province of Avellino). The VIGOR project began on the basis of an agreement between the Ministry of Economic Development and the Italian National Research Council, and it deal with the exploitation of innovative uses of geothermal energy in the so-called "regions of convergence"(Campania, Calabria, Puglia and Sicilia). Thanks to the intense hydrocarbon exploration, carried out particularly during the 1956-1996 period, an extensive data set made up by deep wells and seismic reflection profiles exist in the study area. The previous exploration demonstrated the presence of a fractured carbonate reservoir, mainly belonging to the Cretaceous section of the Apulian shallow water carbonate platform (e.g. Scrocca 2010 and references therein), which is deformed to shape a buried antiformal stack. The culmination of the uppermost thrust unit reaches a depth of about 200 m SSL (i.e., about 1100 m below the ground level). The reservoir fluids are made up by a CO2 gas cap, which rests above an accumulation of fresh water in the central and upper part of the culmination of the deep carbonatic acquifer (e.g., Monte Forcuso 1 and 2 wells), and a saline water along the flank of the buried anticline (e.g., Bonito 1 Dir, Ciccone 1 wells). Medium enthalpy geothermal resources with a reservoir fluid temperature up to 100°C have been estimated in previous assessments at depth of 2000 m below ground level (ENEL 1987; 1994). However, the presence of thermal springs (e.g. Terme di S. Teodoro) in the area suggests the presence of an active hydraulic circuit and provide further constraints about the geochemical characteristics of the reservoir waters, and the geothermometers investigation (Duchi et al. 1995) give a possible reservoir fluid temperature up to about 124 °C.

    This article will present a short introduction into my research on archaeoastronomical studies' origin and development. I deliberately focus my attention on a particular epoch: from the beginning of the 18th century to the 1970s: more precisely 1973, a special positive moment for this field, when anthropologist E.C. Baity generated the neologism of 'ethnoastronomy'. The intention is to describe briefly the romantic hypotheses of the earliest eclectic pioneers - subsequently grouped under the name of astro-archaeologists - combining summaries of the main ideas and quotations. We will be able to reconstruct a valid general overview about the topic in question and the facts - described following a natural chronological development - will guide us to the modern idea of archaeoastronomy. Through two interesting moments during the early twentieth century, but especially at the turn of the 1970s it almost seems that a dialogue may be possible. Thanks to institutions such as the British Academy or Royal Society, and the Accademia Nazionale dei Lincei, a point of convergence bringing together archaeology and astronomy will be established, as well as the promotion of an interdisciplinary research. Might the wall of separation between the arts and the sciences, at least in this field, be overcome? Are we at the threshold of a new discipline? To answer these questions we need a deeper understanding of the contemporary studies on cultural astronomy: a history that develops not only in a linear time, but also growth in complexity and tone, involving more and more scholars belonging to the main scientific and humanistic fields. I would leave this point open inviting my colleagues to join and push forward a research we all totally do need.

    In the last years, thanks to the advances of surveying sensors and techniques, many heritage sites could be accurately replicated in digital form with very detailed and impressive results. The actual limits are mainly related to hardware capabilities, computation time and low performance of personal computer. Often, the produced models are not visible on a normal computer and the only solution to easily visualized them is offline using rendered videos. This kind of 3D representations is useful for digital conservation, divulgation purposes or virtual tourism where people can visit places otherwise closed for preservation or security reasons. But many more potentialities and possible applications are available using a 3D model. The problem is the ability to handle 3D data as without adequate knowledge this information is reduced to standard 2D data. This article presents some surveying and 3D modeling experiences within the APSAT project ("Ambiente e Paesaggi dei Siti d'Altura Trentini", i.e. Environment and Landscapes of Upland Sites in Trentino). APSAT is a multidisciplinary project funded by the Autonomous Province of Trento (Italy) with the aim documenting, surveying, studying, analysing and preserving mountainous and hill-top heritage sites located in the region. The project focuses on theoretical, methodological and technological aspects of the archaeological investigation of mountain landscape, considered as the product of sequences of settlements, parcelling-outs, communication networks, resources, and symbolic places. The mountain environment preserves better than others the traces of hunting and gathering, breeding, agricultural, metallurgical, symbolic activities characterised by different lengths and environmental impacts, from Prehistory to the Modern Period. Therefore the correct surveying and documentation of this heritage sites and material is very important. Within the project, the 3DOM unit of FBK is delivering all the surveying and 3D material to

    The Puget Sound Area Electric Reliability Plan Draft Environmental Impact Statement (DEIS) identifies the alternatives for solving a power system problem in the Puget Sound area. This Plan is undertaken by Bonneville Power Administration (BPA), Puget Sound Power Light, Seattle City Light, Snohomish Public Utility District No. 1 (PUD), and Tacoma Public Utilities. The Plan consists of potential actions in Puget Sound and other areas in the State of Washington. A specific need exists in the Puget Sound area for balance between east-west transmission capacity and the increasing demand to import power generated east of the Cascades. At certain times of the year, there is more demand for power than the electric system can supply in the Puget Sound area. This high demand, called peak demand, occurs during the winter months when unusually cold weather increases electricity use for heating. The existing power system can supply enough power if no emergencies occur. However, during emergencies, the system will not operate properly. As demand grows, the system becomes more strained. To meet demand, the rate of growth of demand must be reduced or the ability to serve the demand must be increased, or both. The plan to balance Puget Sound's power demand and supply has these purposes: The plan should define a set of actions that would accommodate ten years of load growth (1994--2003). Federal and State environmental quality requirements should be met. The plan should be consistent with the plans of the Northwest Power Planning Council. The plan should serve as a consensus guideline for coordinated utility action. The plan should be flexible to accommodate uncertainties and differing utility needs. The plan should balance environmental impacts and economic costs. The plan should provide electric system reliability consistent with customer expectations. 29 figs., 24 tabs.

The existing power system can supply enough power if no emergencies occur. However, during emergencies, the system will not operate properly. As demand grows, the system becomes more strained. To meet demand, the rate of growth of demand must be reduced or the ability to serve the demand must be increased, or both. The plan to balance Puget Sound`s power demand and supply has these purposes: The plan should define a set of actions that would accommodate ten years of load growth (1994--2003). Federal and State environmental quality requirements should be met. The plan should be consistent with the plans of the Northwest Power Planning Council. The plan should serve as a consensus guideline for coordinated utility action. The plan should be flexible to accommodate uncertainties and differing utility needs. The plan should balance environmental impacts and economic costs. The plan should provide electric system reliability consistent with customer expectations. 29 figs., 24 tabs.

    In accordance with the National Environmental Policy Act (NEPA) of 1969, the US Department of Energy (DOE) has prepared this document as environmental input to future decisions regarding the Waste Isolation Pilot Plant (WIPP), which would include the disposal of transuranic waste, as currently authorized. The alternatives covered in this document are the following: (1) Continue storing transuranic (TRU) waste at the Idaho National Engineering Laboratory (INEL) as it is now or with improved confinement. (2) Proceed with WIPP at the Los Medanos site in southeastern New Mexico, as currently authorized. (3) Dispose of TRU waste in the first available repository for high-level waste. The Los Medanos site would be investigated for its potential suitability as a candidate site. This is administration policy and is the alternative preferred by the DOE. (4) Delay the WIPP to allow other candidate sites to be evaluated for TRU-waste disposal. This environmental impact statement is arranged in the following manner: Chapter 1 is an overall summary of the analysis contained in the document. Chapters 2 and 4 set forth the objectives of the national waste-management program and analyze the full spectrum of reasonable alternatives for meeting these objectives, including the WIPP. Chapter 5 presents the interim waste-acceptance criteria and waste-form alternatives for the WIPP. Chapters 6 through 13 provide a detailed description and environmental analysis of the WIPP repository and its site. Chapter 14 describes the permits and approvals necessary for the WIPP and the interactions that have taken place with Federal, State, and local authorities, and with the general public in connection with the repository. Chapter 15 analyzes the many comments received on the DEIS and tells what has been done in this FEIS in response. The appendices contain data and discussions in support of the material in the text.

  17. A regional adaptive and assimilative three-dimensional ionospheric model

    A regional adaptive and assimilative three-dimensional (3D) ionospheric model is proposed. It is able to ingest real-time data from different ionosondes, providing the ionospheric bottomside plasma frequency fp over the Italian area. The model is constructed on the basis of empirical values for a set of ionospheric parameters Pi[base] over the considered region, some of which have an assigned variation ΔPi. The values for the ionospheric parameters actually observed at a given time at a given site will thus be Pi = Pi[base] + ΔPi. These Pi values are used as input for an electron density N(h) profiler. The latter is derived from the Advanced Ionospheric Profiler (AIP), which is software used by Autoscala as part of the process of automatic inversion of ionogram traces. The 3D model ingests ionosonde data by minimizing the root-mean-square deviation between the observed and modeled values of fp(h) profiles obtained from the associated N(h) values at the points where observations are available. The ΔPi values are obtained from this minimization procedure. The 3D model is tested using data collected at the ionospheric stations of Rome (41.8N, 12.5E) and Gibilmanna (37.9N, 14.0E), and then comparing the results against data from the ionospheric station of San Vito dei Normanni (40.6N, 18.0E). The software developed is able to produce maps of the critical frequencies foF2 and foF1, and of fp at a fixed altitude, with transverse and longitudinal cross-sections of the bottomside ionosphere in a color scale. fp(h) and associated simulated ordinary ionogram traces can easily be produced for any geographic location within the Italian region. fp values within the volume in question can also be provided.

    The analysis of stratigraphy and of pyroclastic deposits particle features allowed the reconstruction of the volcanic history of La Fossa di Vulcano. An eruptive scenario driven by superficial phreatomagmatic explosions emerged. A statistical analysis of the pyroclastic Successions led to define a repetitive sequence of dilute pyroclastic density currents as the most probable events at short term, followed by fallout of dense ballistic blocks. The scale of such events is related to the amount of magma involved in each explosion. Events involving a million of cubic meters of magma are probable in view of what happened in the most recent eruptions. They led to the formation of hundreds of meters thick dilute pyroclastic density currents, moving down the volcano slope at velocities exceeding 50 m/sec. The dispersion of desnity currents affected the whole Vulcano Porto area, the Vulcanello area and also overrode the Fossa Caldera's rim, spreading over the Piano area. Similarly, older pyroclastic deposits erupted at different times (Piano Grotte dei Rossi formation, ~20-7.7 ka) from vents within La Fossa Caldera and before La Fossa Cone formation. They also were phreatomagmatic in origin and fed dilute pyroclastic density currents (PDC). They represent the eruptions with the highest magnitude on the Island. Therefore, for the aim of hazard assessment, these deposits from La Fossa Cone and La Fossa Caldera were used to depict eruptive scenarios at short term and at long term. On the base of physical models that make use of pyroclastic deposits particle features, the impact parameters for each scenario have been calculated. They are dynamic pressure and particle volumetric concentration of density currents, and impact energy of ballistic blocks. On this base, a quantitative hazard map is presented, which could be of direct use for territory planning and for the calculation of the expected damage.

    This study examines how dietary macronutrient-induced changes in voluntary food intake (FI) relate to changes in markers of hepatic oxidative metabolism and in the expression of FI regulatory neuropeptides in a teleost model, the rainbow trout. Rainbow trout were fed for 6weeks with one of four iso-energetic diets (2×2 factorial design), containing either a high (HP, ~500 g·kg(-1) DM) or a low (LP, ~250 g·kg(-1) DM) protein level (PL) with, at each PL, fat (diets HP-F and LP-F) being substituted by an iso-energetic amount of gelatinized corn starch (diets HP-St and LP-St) as non-protein energy source (ES). Irrespective of the dietary PL, FI (g·kg(-0.8)·d(-1)) and digestible energy intake (DEI, kJ·kg(-0.8)·d(-1)) were significantly (P<0.05) reduced by the iso-energetic replacement of fat by starch as non-protein ES. Interestingly, trout fed these St-diets had higher gene expression of markers of hepatic oxidative phosphorylation (OxPhos), i.e., ubiquinol-cytochrome c reductase subunit 2 (UCR2) and cytochrome oxidase subunit 4 (COX4) and of aerobic oxidative capacity (CS, citrate synthase), which paralleled glucokinase (GK) transcription. This positive relation suggests that glucose phosphorylation and markers of mitochondrial OxPhos are linked at the hepatic level and possibly triggered the observed reduction in FI. Moreover, trout displaying the reduced FI had higher cocaine amphetamine regulator transcript (CART) mRNA in hypothalamus, whereas neuropeptide Y (NPY) mRNA did not follow the macronutrient-induced changes in FI. Further studies are needed to unravel the mechanisms by which diet-induced changes in hepatic metabolism inform central feeding centers involved in the regulation of FI in fish. PMID:22484564

    This special issue of Journal of Physics: Condensed Matter gathers together a series of contributions presented at the workshop entitled `Topics in the Application of Scattering Methods to Investigate the Structure and Dynamics of Soft Condensed Matter' held at Pensione Bencista, Fiesole, Italy, a wonderful Italian jewel tucked high in the hills above Florence. This immaculate 14th century villa is a feast for the eyes with antiques and original artwork everywhere you turn, and a stunning view of Florence, overlooking numerous villas and groves of olive trees. The meeting consisted of about 40 invited talks delivered by a selected group of prominent physicists and chemists from the USA, Mexico, Europe and Asia working in the fields of complex and glassy liquids. The topics covered by the talks included: simulations on the liquid-liquid transition phenomenon dynamic crossover in deeply supercooled confined water thermodynamics and dynamics of complex fluids dynamics of interfacial water structural arrest transitions in colloidal systems structure and dynamics in complex systems structure of supramolecular assemblies The choice of topics is obviously heavily biased toward the current interests of the two organizers of the workshop, in view of the fact that one of the incentives for organizing the meeting was to celebrate Sow-Hsin Chen’s life-long scientific activities on the occasion of his 70th birthday. The 21 articles presented in this issue are a state-of-the-art description of the different aspects reported at the workshop from all points of view---experimental, theoretical and numerical. The interdisciplinary nature of the talks should make this special issue of interest to a broad community of scientists involved in the study of the properties of complex fluids, soft condensed matter and disordered glassy systems.

    A priori global identifiability is a structural property of biological and physiological models. It is considered a prerequisite for well-posed estimation, since it concerns the possibility of recovering uniquely the unknown model parameters from measured input-output data, under ideal conditions (noise-free observations and error-free model structure). Of course, determining if the parameters can be uniquely recovered from observed data is essential before investing resources, time and effort in performing actual biomedical experiments. Many interesting biological models are nonlinear but identifiability analysis for nonlinear system turns out to be a difficult mathematical problem. Different methods have been proposed in the literature to test identifiability of nonlinear models but, to the best of our knowledge, so far no software tools have been proposed for automatically checking identifiability of nonlinear models. In this paper, we describe a software tool implementing a differential algebra algorithm to perform parameter identifiability analysis for (linear and) nonlinear dynamic models described by polynomial or rational equations. Our goal is to provide the biological investigator a completely automatized software, requiring minimum prior knowledge of mathematical modelling and no in-depth understanding of the mathematical tools. The DAISY (Differential Algebra for Identifiability of SYstems) software will potentially be useful in biological modelling studies, especially in physiology and clinical medicine, where research experiments are particularly expensive and/or difficult to perform. Practical examples of use of the software tool DAISY are presented. DAISY is available at the web site http://www.dei.unipd.it/~pia/. PMID:17707944

  2. High level triggers for explosive mafic volcanism: Albano Maar, Italy

    Colli Albani is a quiescent caldera complex located within the Roman Magmatic Province (RMP), Italy. The recent Via dei Laghi phreatomagmatic eruptions led to the formation of nested maars. Albano Maar is the largest and has erupted seven times between ca 69-33 ka. The highly explosive nature of the Albano Maar eruptions is at odds with the predominant relatively mafic (SiO2 = 48-52 wt.%) foiditic (K2O = 9 wt.%) composition of the magma. The deposits have been previously interpreted as phreatomagmatic, however they contain large amounts (up to 30%vol) of deep seated xenoliths, skarns and all pre-volcanic subsurface units. All of the xenoliths have been excavated from depths of up to 6 km, rather than being limited to the depth at which magma and water interaction is likely to have occurred, suggesting an alternative trigger for eruption. High precision geochemical glass and mineral data of fresh juvenile (magmatic) clasts from the small volume explosive deposits indicate that the magmas have evolved along one of two evolutionary paths towards foidite or phonolite. The foiditic melts record ca. 50% mixing between the most primitive magma and Ca-rich melt, late stage prior to eruption. A major result of our study is finding that the generation of Ca-rich melts via assimilation of limestone, may provide storage for significant amounts of CO2 that can be released during a mixing event with silicate magma. Differences in melt evolution are inferred as having been controlled by variations in storage conditions: residence time and magma volume.

  3. p53 and bcl-2 expression in high-grade B-cell lymphomas: correlation with survival time.

    B-cell high-grade lymphomas are heterogeneous in terms of histology, clinical presentation, treatment response and prognosis. As bcl-2 and p53 gene deregulations are frequently involved in several types of lymphoid malignancies, we aimed our investigation at the study of the relation between bcl-2 and p53 expression and survival probability in a group of 119 patients with B-cell high-grade lymphoma. These were obtained from the Virgen de la Salud Hospital, Toledo, Spain (73 cases), John Radcliffe Hospital, Oxford, UK (31 cases), and the Istituto Nazionale dei Tumori, Milan, Italy (15 cases). The relation between bcl-2 protein expression and survival was small, depending on the primary localisation of the tumour (in lymph node of mucosae), and lacked a significant correlation with overall survival. In contrast with this, p53 expression was related to survival probability in our series, this relation being both significant and independent of histological diagnosis. p53-positive patients showed a sudden decrease in life expectancy in the first months after diagnosis. Multivariant regression analysis confirmed that the only parameters significantly related with survival were extranodal origin, which is associated with a better prognosis, and p53 expression, which indicates a poor prognosis. Simultaneous expression of bcl-2 and p53 was associated with a poorer prognosis than p53 alone. This is particularly significant for large B-cell lymphomas presenting in lymph nodes. The cumulative poor effect of both p53 and bcl-2 in large B-cell lymphomas, which is more significant in nodal tumours, could confirm the existence of a multistep genetic deregulation in non-Hodgkin's lymphoma. This indicates that the genetic mechanisms controlling apoptosis and their disregulation are critical steps in the progression of lymphomas. PMID:8297731

    It is considered that the structural damage in early osteoarthritis (OA) is potentially reversible. It is therefore particularly important for orthopaedic and trauma surgery to develop strategies and technologies for diagnosing early OA processes. This review presents 3 case reports to illustrate the current clinical diagnostic procedure for OA. Experimental techniques with translational character are discussed in the context of the detection of early degenerative processes relevant to OA. Non-invasive imaging methods such as quantitative MRI, ultrasound, optical coherence tomography (OCT), scintigraphy and diffraction-enhanced synchrotron imaging (DEI), as well as biochemical methods and proteomics, are considered. Early detection of OA is reviewed with minimally invasive techniques, such as arthroscopy, as well as the combination of arthroscopic techniques with indentation, spectrometry, and multiphoton microscopy. In addition, a brief summary of macroscopic and histologic scores is presented. Finally, the spatial organisation of joint surface chondrocytes as an image-based biomarker is used to illustrate an early OA detection strategy that focusses on early changes in tissue architecture potentially prior to damage. In summary, multiple translational techniques are able to detect early OA processes but we do not know whether they truly represent the initial events. Moreover, at this point it is difficult to judge the future clinical relevance of these procedures and to compare their efficacy, as there have been comparative studies. However, the expected gain in knowledge will hopefully help us top attain a more comprehensive understanding of early OA and to develop novel methods for its early diagnosis, therapy, and prevention. Overall, the clinical diagnosis of early OA remains one of the greatest challenges of our field. We still face uncharted territory. PMID:26894867

    SALVEREMO project aims at designing and prototyping an innovative system for searching and rescuing individuals (especially hikers and mountaineers) who got lost or in peril in wilderness or mountain areas. It makes use of Remotely Piloted Aircraft System (RPAS) equipped with a sensor suite specifically selected according to the requirements identified involving alpine rescuers and government officials. The peculiarity of the proposed solution is the exploitation and integration of the special skill and expertise coming from different competence fields. It will dramatically decrease the searching time in the wilderness and remote areas off the beaten tracks, providing rescuers and operators with a decision support system increasing successful results and reducing rescue missions costs. The system benefits from the adoption of a scaled-down Base Transceiver Station (BTS) embarked in the payload sensor suite of a small RPAS that can be carried in a back pack of rescuers. A Software Defined Radio (SDR) board implementing the BTS protocol stack has been integrated in a complex sensor suite made up of open processing boards and camera devices. Moreover computer vision (CV) algorithms for real time pattern detection and image enhancements have been investigated for assisting the rescuers during the searching operations. An easy-to-use ground station application has been developed for speeding up the overall mission accomplishment. Aknowledgement SALVEREMO project is a research project co-funded by Regione Piemonte according to the call for proposal POR F.E.S.R. 2007/2013, "Linea di attività I.1.3-Innovazione e PMI - Polo della Meccatronica e dei Sistemi Avanzati di Produzione".

  7. Late-stage magmatic processes at Albano Maar, Colli Albani, Italy: insights from FTIR analysis of leucites

    The recently erupted Albano Maar, one of the Via dei Laghi phreatomagmatic eruptions of Colli Albani, Italy have eruptive deposits that are K-foiditic (9wt% K2O) and silica under-saturated (48-52wt% SiO2). These compositions suggest the melts are low viscosity [1, 2], but they fuelled very explosive eruptions, namely the widespread large Peperino ignimbrite (phreato-Plinian) deposits. Therefore a question asked by researchers is how could these melts explode and would they, if they had not interacted with groundwater? Experimental work has shown that the melt chemistries at Colli Albani require a volatile saturated system [3]. Consequently the CO2 and H2O content of the melts are critical to understanding the petrogenetic processes at Albano Maar. Since the juvenile tephra clasts exhibit extensive late stage micro-crystallization (mainly leucite), analysis of glass is difficult and not representative as the majority of the volatile components may have exsolved from the melt. Melt inclusions are also commonly recrystallized and often leaky so here we unravel the complex volatile histories of the melts using the abundant leucite crystals, which have been shown to contain magmatic water in recent studies [4]. FTIR analysis of leucite phenocrysts and microcrysts within juvenile tephra clasts (syn-eruptive) of all the erupted units at Albano Maar provide an interesting insight into volatile variations and record a late stage CO2 fluxing event, which would have contributed to the explosive nature of the eruptions. This study has also allowed for an increased understanding of the nominally anhydrous minerals (NAMs) that crucially record volatile speciation and fluxing in high level magmatic systems.

    Bonneville is responsible for maintaining a network of 24,000 kilometers (km) or 15,000 miles (mi.) of electric transmission lines and 350 substations in a region of diverse vegetation. This vegetation can interfere with electric power flow, pose safety problems for us and the public, and interfere with our ability to maintain these facilities. We need to (1) keep vegetation away from the electric facilities; (2) increase the program efficiency and consistency; (3) review herbicide use (under increased public scrutiny); and (4) maximize the range of tools we can use while minimizing environmental impact (Integrated Vegetation Management). This DEIS establishes Planning Steps for managing vegetation for specific projects (to be tiered to this EIS). In addition to No Action (current practice), alternatives are presented for Rights-of-way, Electric Yards, and Non-electric Facilities (landscaping, work yards). Four vegetation control methods are analyzed: manual, mechanical, herbicide, and biological. Also evaluated are 24 herbicide active ingredients and 4 herbicide application techniques (spot, localized, broadcast, and aerial). For rights-of-way, they consider three sets of alternatives: alternative management approaches (time-driven or establishing low-growing plant communities); alternative method packages; and, if herbicides are in a methods package, alternative vegetation selections (noxious weeds, deciduous, or any vegetation). For electric yards, one herbicide-use alternative is considered. For non-electric facilities, two method package alternatives are considered. For rights-of-way, the environmentally preferred alternative(s) would use manual, mechanical, and biological control methods, as well as spot and localized herbicide applications for noxious and deciduous plant species; the BPA-preferred alternative(s) would add broadcast and aerial herbicide applications, and would use herbicides on any vegetation. Both would factor a management approach that

    One of the most important challenges for embodied and grounded theories of cognition concerns the representation of abstract concepts, such as “freedom.” Many embodied theories of abstract concepts have been proposed. Some proposals stress the similarities between concrete and abstract concepts showing that they are both grounded in perception and action system while other emphasize their difference favoring a multiple representation view. An influential view proposes that abstract concepts are mapped to concrete ones through metaphors. Furthermore, some theories underline the fact that abstract concepts are grounded in specific contents, as situations, introspective states, emotions. These approaches are not necessarily mutually exclusive, since it is possible that they can account for different subsets of abstract concepts and words. One novel and fruitful way to understand the way in which abstract concepts are represented is to analyze how sign languages encode concepts into signs. In the present paper we will discuss these theoretical issues mostly relying on examples taken from Italian Sign Language (LIS, Lingua dei Segni Italiana), the visual-gestural language used within the Italian Deaf community. We will verify whether and to what extent LIS signs provide evidence favoring the different theories of abstract concepts. In analyzing signs we will distinguish between direct forms of involvement of the body and forms in which concepts are grounded differently, for example relying on linguistic experience. In dealing with the LIS evidence, we will consider the possibility that different abstract concepts are represented using different levels of embodiment. The collected evidence will help us to discuss whether a unitary embodied theory of abstract concepts is possible or whether the different theoretical proposals can account for different aspects of their representation.

    Occupation of the coast has significantly increased in recent decades, mostly due to a greater demand for recreation and tourism. Today, erosion threatens many human-made structures and activities, requiring an integrated approach for the understanding of coastal dynamics and identification of alternatives to associated problems. This study investigates a 64 km-long coastal physiographic unit in the northern microtidal littoral of Tuscany (Italy). Vertical aerial photographs and direct field surveys were used to retrieve changes in shoreline position over 1938-1997 and 1997-2005 time intervals. Significant beach accretion was observed during the first period updrift of Carrara (84 m) and Viareggio (280 m) harbours and at Marina di Pietrasanta (100 m), whereas severe erosion occurred downcoast of Carrara harbour (- 130 m, at Marina dei Ronchi) and on the northern side of Arno river mouth (- 400 m). Similar trends were observed between 1997 and 2005; beach slope between the 1997 shoreline position and the closure depth correlated well with the distribution of erosion/accretion patterns from the 1938-1997 period (slopes were lower in eroded areas than at sites under accretion). Longshore distribution of erosion/accretion patterns was controlled by coastal compartmentalisation. Three of the main littoral cells were mostly formed by natural limits (i.e., Punta Bianca promontory, Marina di Pietrasanta, the Arno river mouth and the port of Livorno). Several sub-cells were created within these cells due to the introduction of human-made structures (such as Carrara and Viareggio harbours), which formed artificial fixed limits that allowed the transport of sediments (exclusively fines) in one direction only. Results will help improve the understanding of coastal processes and manage littoral sediment transport in a sustainable manner. This will reduce the need for structural interventions, such as breakwaters and groynes, which in the past decades prevented coastal retreat

    This document describes the hardware and software required for the Federal Emergency Management Information System version 1.4.5 (FEMIS v1.4.5). The FEMIS system is designed for a single Chemical Stockpile Emergency Preparedness Program (CSEPP) site that has multiple Emergency Operations Centers (EOCs). Each EOC has personal computers (PCs) that emergency planners and operations personnel use to do their jobs. These PCs are connected via a local area network (LAN) to servers that provide EOC-wide services. Each EOC is interconnected to other EOCs via a Wide Area Network (WAN). A UNIX server provides a platform to support the Oracle relational database management system (RDBMS) distributed by Pacific Northwest National Laboratory (PNNL), ARC/INFO geographic information system (GIS) capabilities (optional), basic file management services, the evacuation model (ESIM), the data exchange interface (DEI), and the notification service. FEMIS is a client/server system where much of the application software is located in the client PC. This client software includes the FEMIS application, government furnished dispersion and evacuation models, and Commercial-Off-The-Shelf (COTS) software applications, including the ArcView GIS and Microsoft Project (electronic planning). Several configurations are possible at a CSEPP site. In this document, a site is understood to include several installations of FEMIS, including the Depot, surrounding Immediate Response Zone (IRZ) and Protective Action Zone (PAZ) counties, and one or more state EOCs. In general, the main differences between possible configurations are the numbers of PC workstations at an installation, the location of the UNIX server(s), and the WAN links between installations.

  13. Draft Environmental Impact Statement for the Ulysses Mission (Tier 2)

    NASA Technical Reports Server (NTRS)

    1990-01-01

    This Draft Environmental Impact Statement (DEIS) addresses the environmental impacts which may be caused by the preparation and operation of the Ulysses spacecraft, including its planned launch on the Space Transportation System (STS) Shuttle and the alternative of canceling further work on the mission. The launch configuration will use the STS/Inertial Upper Stage (IUS)/Payload Assist Module-Special(PAM-S) combination. The Tier 1 EIS included a delay alternative which considered the Titan 4 launch vehicle as an alternative booster stage for launch in 1991 or later. However, the U.S. Air Force, which procures the Titan 4 for NASA, could not provide a Titan 4 vehicle for the 1991 launch opportunity because of high priority Department of Defense requirements. The only expected environmental effects of the proposed action are associated with normal Shuttle launch operations. These impacts are limited largely to the near-field at the launch pad, except for temporary stratospheric ozone effects during launch and occasional sonic boom effects near the landing site. These effects have been judged insufficient to preclude Shuttle launches. In the event of (1) an accident during launch, or (2) reentry of the spacecraft from earth orbit, there are potential adverse health and environmental effects associated with the possible release of plutonium dioxide from the spacecraft's radioisotope thermoelectric generators (RTG). The potential effects considered in this EIS include risks of air and water quality impacts, local land area contamination, adverse health and safety impacts, the disturbance of biotic resources, impacts on wetland areas or areas containing historical sites, and socioeconomic impacts. Intensive analysis of the possible accidents associated with the proposed action are underway and preliminary results indicate small health or environmental risks. The results of a Final Safety Analysis Report will be available for inclusion into the final EIS.

    Built on the first half of the XVI century, under Federico II Gonzaga, Duke of Mantova, Palazzo Te is one of the most relevant Italian monuments and it belongs to the UNESCO World Heritage List; the Camera dei Giganti (Chamber of the Giants) hosts a famous XVI century Giulio Romano fresco. Palazzo Te raises concerns in particular for the statics of the Fruttiere external wall and for some fissures that cross the above mentioned fresco. Therefore a monitoring survey has been undertaken to detect and qualify the vibrations caused by earthquakes and anthropic activity. Palazzo Te is situated in a low seismicity area, nevertheless even weak earthquakes could result in significant damage due to the poor soil conditions. A seismic station deployed inside the Palazzo Te recorded, on July 17, 2011, 2 cm/sec2 PGA for the ML 4.7 earthquake located at approx 51 km distance: some light damage has been observed. As far as vibrations due to anthropic origin, the station has evidenced that the major threat is due to the trains at the nearby railway: inside the Palazzo Te PGA reached 5 cm/sec2. The seismic survey led to the following considerations: 1. even low magnitude earthquakes can be a threat, given the intrinsic vulnerability of some parts of the Palazzo Te; 2. the main and possibly unique significant dangerous vibrations of anthropic origin come from the trains running nearby; 3. the response spectra evidenced that the earthquake had a consistent energy content till T0=2 seconds, while the spectrum of the trains decay abruptly at around 10 Hz. In contrast the train response spectrum is significantly higher in the high frequency range. In conclusion, despite the relatively low hazard, seismic risk is still relevant, because of the poor soil conditions coupled with the high vulnerability. The train vibrations are not a threat for the Palazzo Te structure but can cause some concerns to the frescoes.

    Objective: To prospectively assess the surgical results from patients undergoing repairs to rotator cuff injuries via open and arthroscopic procedures, with regard to functional and clinical features, and by means of ultrasound examinations, and to compare occurrences of renewed tearing. Methods: Sixty patients underwent operations performed by the same surgeon (29 via open surgery and 31 via arthroscopy), to repair complete rotator cuff tears. The procedures were performed at Hospital Governor Israel Pinheiro (HGIP) and Mater Dei Hospital in Belo Horizonte, Minas Gerais, between August 2007 and February 2009. The patients were assessed functionally by means of the UCLA score before and after the operation, and magnetic resonance imaging was done before the operation. All the patients were reassessed at least 12 months after the operation, and an ultrasound examination was also performed at this time. Results: Out of the 29 patients who underwent open surgery, 27 (93.1%) presented good or excellent results, with a mean UCLA score of 32 after the operation. Their mean follow-up was 14 months. Three patients presented renewed tearing on ultrasound, of whom one remained asymptomatic. Out of the 31 patients who underwent arthroscopic procedures, 29 (93.5%) presented good or excellent results, with a mean UCLA score of 33 after the operation. Their mean follow-up was 19 months. Two patients presented renewed tearing, of whom one remained asymptomatic and one evolved with loosening of an anchor, with an unsatisfactory result. Conclusion: The repairs on rotator cuff injuries presented good results by means of both open surgery and arthroscopy, with similar functional results in the two groups and similar rates of renewed tearing.

    In recent years, effective models of disaster medicine curricula for medical schools have been established. However, only a small percentage of medical schools worldwide have considered at least basic disaster medicine teaching in their study program. In Italy, disaster medicine has not yet been included in the medical school curriculum. Perceiving the lack of a specific course on disaster medicine, the Segretariato Italiano Studenti in Medicina (SISM) contacted the Centro di Ricerca Interdipartimentale in Medicina di Emergenza e dei Disastri ed Informatica applicata alla didattica e alla pratica Medica (CRIMEDIM) with a proposal for a nationwide program in this field. Seven modules (introduction to disaster medicine, prehospital disaster management, definition of triage, characteristics of hospital disaster plans, treatment of the health consequences of different disasters, psychosocial care, and presentation of past disasters) were developed using an e-learning platform and a 12-hour classroom session which involved problem-based learning (PBL) activities, table-top exercises, and a computerized simulation (Table 1). The modules were designed as a framework for a disaster medicine curriculum for undergraduates and covered the three main disciplines (clinical and psychosocial, public health, and emergency and risk management) of the core of "Disaster Health" according to the World Association for Disaster and Emergency Medicine (WADEM) international guidelines for disaster medicine education. From January 2011 through May 2013, 21 editions of the course were delivered to 21 different medical schools, and 524 students attended the course. The blended approach and the use of simulation tools were appreciated by all participants and successfully increased participants' knowledge of disaster medicine and basic competencies in performing mass-casualty triage.

  17. A journey toward wholeness, a journey to God: physical fitness as embodied spirituality.

    2013-09-01

    Physical fitness expressed through exercise can be, if done with the right intention, a form of spiritual discipline that reflects the relational love of humanity to God as well as an expression of a healthy love of the embodied self. Through an analysis of the physiological benefits of exercise science applied to the human body, this paper will demonstrate how such attention to the optimal physical fitness of the body, including weight and cardiovascular training and nutrition, is an affirmation of three foundational theological principles of human embodiment: as created in the "imago Dei", as unified body/spirit, and as part of God's creation calling for proper stewardship. In a contemporary climate where women's bodies in particular are viewed through the lens of commodification-as visual objects for sale based on prescribed notions of superficial esthetics and beauty-as well as the consistently high rates of eating disorders such as anorexia, bulimia, and obesity, authors Greenwood and Delgado offer a vision of how women and men can imagine a subjective relationship with their own bodies that reflects the abundant love of God for God's creation. Spoken from the lived experience of professional fitness competitor and trainer, as well as trained biokineticist, Dr. Greenwood presents the most current scientific data in the field of biokinetics that grounds the theological analysis offered by Dr. Delgado, whose personal journey through anorexia and scholarly emphasis on Christian theological anthropology inform this work. Taken together, Greenwood and Delgado suggest a response to God's love for humanity, including our physical bodily humanity, which entails a responsibility to attend to the physical fitness of our bodies in order to live into the fullness, flourishing and love of God's creation as God intended.

    criteria to account for the homogeneity/heterogeneity of a given current field in the vicinity of any kind of structure. Additionally, the bottom nepheloïd layer, demonstrated to be present during the whole experiment by transmissometer measurements, was expected to be uplifted and inclined above the observatory. In such conditions, Echo Intensities (EI) of beams standing in the observatory's wake were expected to be higher than those outside the wake. This was checked by studying the link between the current direction and a quantity (DEi) that is the difference between the EI on a given beam and the average of the three other EI's on the other beams at a given depth. Results are very convincing and show that the DEi effectively reach their highest values when currents are oriented toward the related beam. In addition, the DEi's analysis shows that the wake can reach the surface. Numerical simulations of the current field around the observatory were also performed using the CFD (Computational Fluid Dynamics) software FLUENT (2000). The effect of turbulence was considered by means of a k-epsilon model and the near-wall layer was approximated by a standard logarithmic function approach. The observatory was modelled as a block of 2.5x2.5x1 m super (3) and the overall volume around it (45x20x40 m super (3)) was discretized in about 380000 elementary volumes. For these simulations, two values of the mean current (10 cm/s and 30 cm/s) and two configurations for the observatory's orientation (current parallel to sides or to a diagonal) were considered. Although the current lines do not appear to be strongly modified by the observatory, vertical velocities are induced over the whole water depth. Maximum values that could be compared to those from the ADCP, ie at 5m asf, reach about 10 mm/s and values of about 1 mm/s are still encountered at about 15 m asf. Although the modelled vertical velocities appear weaker than the data, they convincingly confirm the disturbance

  1. Evidences for the austroalpine - southalpine up-doming after the end of the variscan orogenesis (central and eastern alps)

    The structural and petrographic studies of the basement units in the Alpine region, independently from their present tectonic setting in the nappe pile, suggest that at the end of the Variscan orogenesis they were in such a position that they suffered relevant up-doming and cooling since Late Carboniferous (Thöni, 1981; Mottana et al., 1985; Martin et al., 1996; Bertotti et al., 1999). This up-doming has been interpreted as due to an isostatic rebound related to the detachment of the slab after the cessation of the subduction at the end of the Variscan orogenesis (Neubauer and Handler, 2000; Ranalli, 2003). The metamorphic setting of the Southalpine basement between the Tonale pass and Lake Maggiore in the Southern Alps, is due to processes which, by extension denudation and erosion, locally took to the surface portions of middle-to-high grade basement, within a horst-graben environment (Cassinis et al., 1997). The basements of the Orobic, Lake Como and Lake Maggiore areas are composed of kyanite-garnet or sillimanite-bearing schists (e.g., Gneiss di Morbegno, Scisti di Edolo, Scisti dei Laghi; Boriani et al., 1990; Siletto et al., 1993), or of low grade schists (e.g., Filladi di Ambria) intruded by Early Permian plutons, covered by continental and volcanic deposits of Late Carboniferous to Permian age, after a marked unconformity (Cadel et al., 1996). The thickness of this clastic cover ranges between a few hundreds to thousands of meters; the clast compositions suggest a low-grade basement as a dominant source; the structures indicate alternance of uplift and collapse and continue deformation during sedimentation (Cassinis et al., 1974). Most of the Upper Austroalpine units of the central and eastern Alps (e.g., Tonale nappe, Languard, Ortles and Campo units) have structural and lithological similarities with the Orobic, Lake Como and Lake Maggiore basement units confirming their appartenance to the same pre-Alpine paleogeographic environment which suffered up

    During the TAMEX (Tamyneon Air pollution Mini EXperiment) field Campaign, which took place in the industrial site of Aliveri (38o,24'N, 24o 01'E), Evia (Greece) between June 25 and September 25, 2008, continuous measurements of airborne particulate matter (PM) were performed by in situ sensors at ground level. Additional aerosol measurements were performed by a single-wavelength (355 nm) eye-safe scanning lidar, operating in the Range-Height Indicator (RHI) mode between July 22 and 23, 2008. The industrial site of the city of Aliveri is located south-east of the city area at distance of about 2.5 km. The in situ aerosol sampling site was located at the Lykeio area at 62 m above sea level (ASL) and at a distance of 2,8 km from the Public Power Corporation complex area (DEI Corporation) and 3,3 km from a large cement industrial complex owned by Hercules/Lafarge SA Group of Companies (HLGC) and located at Milaki area. According to the European Environment Agency (EEA) report for the year 2004, this industry emits about 302 tons per year of PM10, 967,000 tons of CO2, 16700 tons of SOx and 1410 tons of NOx while the second industrial complex (HLGC) emits about 179 tons per year of PM10, 1890 tons of CO, 1,430,000 tons of CO2, 3510 tons of NOx, 15.4 Kg of cadmium and its compounds, 64.2 kg of mercury and its compounds and 2.2 tons of benzene. The measuring site was equipped with a full meteorological station (Davis Inc., USA), and 3 aerosol samplers: two Dust Track optical sensors from TSI Inc. (USA) and 1 Skypost PM sequential atmospheric particulate matter. The Dust Track sensors monitored the PM10, PM2.5 and PM1.0 concentration levels, with time resolution ranging from 1 to 3 minutes, while a Tecora sensor was taking continuous PM monitoring by the sampling method on 47 mm diameter filter membrane. The analysis of the PM sensors showed that, systematically, during nighttime large quantities of PM2.5 particles were detected (e.g. exceeding 50 ug/m3). During daytime

    One of the strongest predictors of colorectal cancer risk is carrying a germline mutation in a DNA mismatch repair (MMR) gene. Once identified, mutation carriers can be recommended for intensive screening that will substantially reduce their high colorectal cancer risk. Conversely, the relatives of carriers identified as non-carriers can be relieved of the burden of intensive screening. Criteria and prediction models that identify likely mutation carriers are needed for cost-effective, targeted, germline testing for MMR gene mutation. We reviewed 12 criteria/guidelines and 8 prediction models (Leiden, Amsterdam-plus, Amsterdam-alternative, MMRpro, PREMM1,2,6, MMRpredict, Associazione Italiana per lo studio della Familiarità ed Ereditarietà dei tumori Gastrointestinali (AIFEG) and the Myriad Genetics Prevalence table) for identifying mutation carriers. While criteria are only used to identify individuals with colorectal cancer (yes/no for screening followed by germline testing), all prediction models except MMRpredict and Myriad tables can predict the probability of carrying mutations for individuals with or without colorectal cancer. We conducted a meta-analysis of the discrimination performance of 17 studies that validated the prediction models. The pooled estimate for the area under curve was 0.80 (95% CI 0.72 to 0.88) for MMRpro, 0.81 (95% CI 0.73 to 0.88) for MMRpredict, 0.84 (95% CI 0.81 to 0.88) for PREMM, and 0.85 (95% CI 0.78 to 0.91) for Leiden model. Given the high degree of overlap in the CIs, we cannot state that one model has a higher discrimination than any of the others. Overall, the existing statistical models have been shown to be sensitive and specific (at a 5% cut-off) in predicting MMR gene mutation carriers. Future models may need to: provide prediction of PMS2 mutations, take into account a wider range of Lynch syndrome-associated cancers when assessing family history, and be applicable to all people irrespective of any cancer diagnosis

    In the outermost domains of the central Apennines fold-and-thrust belt, the structural architecture of the late Miocene-early Pliocene contractional edifice was controlled by competence contrasts in the Calcareous-Marly sequences of Mesozoic-Tertiary age, and by a different state of lithification of the rock units at the onset of deformation. Field data on relative chronology of outcrop-scale structures (cleavage, veins, faults, folds) are presented for the three largest thrust-ramp anticlines of the Marche fold-and-thrust belt: Monte Gorzano, Acquasanta and Montagna dei Fiori-Montagnone. The data show that the timing and geometry of deformation structures differ for: (1) the lower Calcareous interval of late Triassic-early Cretaceous age (LCI) bounded on top by the intermediate detachment (ID) of the Fucoidi Marls; (2) the upper Calcareous-Marly interval (UCMI) of late Cretaceous-Oligocene age; (3) the uppermost detachment zone (UDZ) of lower-middle Miocene age; (4) the topmost Messinian Flysch sequence (FS). In the UDZ early episodes of deformation are manifested by compaction of a poorly lithified sequence followed by pervasive development of layer-parallel pressure-solution cleavage. Reverse faults ramp obliquely across the stratigraphic sequence, and are coated by multiple overgrowths of calcite fibers. These structures are deformed by large, eastward-verging asymmetric folds with N-S axial trends, and are cut by late generations of reverse faults. Normal faults started to develop in the fold backlimbs during the final stages of shortening, in middle-late Pliocene times. These early normal faults were reactivated during episodes of late Pliocene-Pleistocene extensional downfaulting, and are now superposed on the compressional edifice. The UDZ is interpreted to have temporarily sealed the upward escape of fluids during the initial episodes of shortening. Pervasive interlayer flow in the poorly lithified sequence was responsible for development of broken beds

    An accurate high-resolution astronomical time scale is of crucial importance in Earth Sciences. It allows not only to reconstruct astronomical climate forcing but also to precisely date geological events, to determine rates of changes, and to discriminate between cause and effect related to fundamental processes controlling Earth's history. The accuracy, precision and resolution of the geological time scale for the Neogene have improved considerably over the last decades, thanks to the combination of an integrated stratigraphic approach and astronomical tuning, which resulted in the "Astronomically Tuned Neogene Time Scale" (ATNTS2004, ATNTS2012). The most recent ATNTS2012 (Gradstein et al. 2012) includes direct astronomical ages for chron boundaries back to ~15 Ma based on the tuning of marine successions from the Mediterranean. Reversal ages for the interval between 15 and 23 Ma were calculated from a seafloor-spreading-rate history model in combination with limited astronomical control. Completing the Neogene time scale should be exclusively based on deep marine sections. The most suitable section in the Mediterranean is the Monte dei Corvi-La Vedova-Spiaggia della Scalaccia composite section near Ancona in Italy as an integrated stratigraphy and astronomical tuning has been established for the Late to Middle Miocene interval (Hüsing et al. 2007, 2009, 2010, Mourik et al. 2010, Turco et al. 2011). The resultant astronomically tuned reversal ages have already been incorporated into the GTS (Gradstein et al. 2012). The section has now been further extended into the Early Miocene along the cliffs near Ancona (Spiaggia della Scalaccia composite section). We will present our high-resolution integrated stratigraphy including cyclostratigraphy, biostratigraphy, magnetostratigraphy, colour and elemental proxy records. The sedimentary cycle pattern is very complex in this interval, and we thus use the detailed colour and elemental proxy records to achieve a match with

    Late Messinian Lago-Mare deposits show high-frequency cyclicity in the whole Mediterranean Basin. Both millimeter- and centimeter-scale cyclicities have been observed in several ODP sites as well as in stratigraphic sections from the Mediterranean borderland. We have analyzed a well-exposed late Messinian Lago-Mare section from the Adriatic side of the central Apennines (Italy). At the Fonte dei Pulcini section (SE Majella Mts.), millimeter- and centimeter-scale white-and-dark couplets have been observed in the field. A 50 cm regular-spaced sampling has been performed in the uppermost 53 m of the late Messinian Lago-Mare clays. On the 107 collected samples, geochemical (CaCO 3 content), mineralogical (XRD analyses), and micropalaeontological investigations have been performed. In addition, SEM and microprobe investigations as well as mineralogical and micropalaeontological analyses have been carried out on single lamina from a 34-cm-thick interval of millimeter-scale laminites. Besides the 10 3 cycles/m and 10 2 cycles/m frequencies observed in the field, spectral analyses performed on the CaCO 3 data set indicated other high-frequency cyclicities: 0.47 cycles/m, 0.35 cycles/m, and 0.17 cycles/m. Taking into account the estimated sedimentation rate, these frequencies correspond, respectively, to periodicities of: 1 year, 10 years, 2.1 kyr, 2.8 kyr, and 5.6 kyr. These sub-Milankovitch cyclicities have been related to annual and sunspot solar activity. The millimeter-scale couplets are interpreted as varves sedimented in an ephemeral water environment marginal to a perennial brackish water lagoonal basin. These varved sediments reflect a marked seasonality characterized by the alternation of arid and more humid climatic phases. The presence of high values of smectite (60-80%) in the clay minerals of the analyzed samples could be a consequence of these climatic oscillations from drier to moister conditions. The climatic scenario suggested in this paper for the late

    Past approaches for assessing the impacts of transporting spent fuel and high-level radioactive waste have not been effectively implemented or have used relatively simple approaches. The Yucca Mountain Draft Environmental Impact Statement (DEIS) analysis considers 83 origins, 34 fuel types, 49,914 legal weight truck shipments, 10,911 rail shipments, consisting of 59,250 shipment links outside Nevada (shipment kilometers and population density pairs through urban, suburban or rural zones by state), and 22,611 shipment links in Nevada. There was additional complexity within the analysis. The analysis modeled the behavior of 41 isotopes, 1091 source terms, and used 8850 food transfer factors (distinct factors by isotope for each state). The model also considered different accident rates for legal weight truck, rail, and heavy haul truck by state, and barge by waterway. To capture the all of the complexities of the transportation analysis, a Microsoft{reg_sign} Access database was created. In the Microsoft{reg_sign} Access approach the data is placed in individual tables and equations are developed in queries to obtain the overall impacts. While the query might be applied to thousands of table entries, there is only one equation for a particular impact. This greatly simplifies the validation effort. Furthermore, in Access, data in tables can be linked automatically using query joins. Another advantage built into MS Access is nested queries, or the ability to develop query hierarchies. It is possible to separate the calculation into a series of steps, each step represented by a query. For example, the first query might calculate the number of shipment kilometers traveled through urban, rural and suburban zones for all states. Subsequent queries could join the shipment kilometers query results with another table containing the state and mode specific accident rate to produce accidents by state. One of the biggest advantages of the nested queries is in validation

    Nel presente lavoro di tesi ci si e' occupati di uno studio sistematico di misure di temperatura ed energia di eccitazione in sistemi nucleari formati in reazioni tra ioni pesanti ad energie intermedie. La temperatura a stata misurata tramite due diversi metodi: rapporto tra le rese di isotopi che differiscono di uno stesso numero di nucleoni ( d/t-3He/4He , 3He/4He -6Li/7Li) - temperatura isotopica -, e rapporto tra le popolazioni degli stati eccitati in frammenti instabili (5Li e 6Li) che decadono in particelle leggere in coincidenza - temperatura di emissione. Le misure in esame sono state effettuate presso i Laboratori Nazionali del Sud per i sistemi 93Nb+93Nb, 93Nb+116,124Sn, 116,120Sn+116,124Sn e 116Sn+93Nb ad energie comprese tra 17 e 40 A MeV. L'apparato di rivelazione era costituito da un odoscopio ad alta granularite (96 telescopi Si (50micron)-Si(300micron)-CsI(Tl) ) e basse soglie di rivelazione, utilizzato sia per identificare risonanze in frammenti eccitati che per misure di rese di isotopi di frammenti con 2<=Z<=6, e dal multirivelatore FIASCO che, grazie alla misura contemporanea di posizione e tempo di volo dei frammenti provenienti dal proiettile (PLF - Projectile Like Fragments) e dal bersaglio (TLF - Target Like Fragment), e' stato utilizzato per misurare direttamente l'energia di eccitazione del sistema in studio. Analisi precedenti, condotte nell'ambito di varie collaborazioni, hanno messo in evidenza la possible esistenza di una transizione di fase liquido-gas del primo ordine nella materia nucleare. In tale contesto, ci siamo occupati di una verifica della curva calorica nucleare, ovvero della correlazione esistente fra temperatura ed energia di eccitazione del sistema, indagando, nel contempo, sulla sua dipendenza dalla massa del sistema che si frammenta. Si e' effettuato, inoltre, un confronto fra i due diversi metodi di misura della temperatura (temperatura isotopica e di emissione): l'andamento plateau-like della curva calorica e' stato

The high correlation showed between observed and computed data can be considered statistically meaningful and hence the model can be deemed a good predictor both for high resolution and for short period of simulation. Moreover the coupling satellite data at high resolution and field information as input data have shown that these data can be used in the 3D-CMCC Forest Model run. These data can be also successfully used to simulate the main physiological processes at regional scale and to produce with good accordance with measured and literature data, reliable output to better investigate forest growth, dynamic and carbon stock.

    Geotube is a project promoted by Il Geco cultural association for the dissemination of Geoscience education in schools by open multimedia environments. The approach is based on the following keystones: • A deep and permanent epistemological reflection supported by confrontation within the International Scientific Community • A close link with the territory • A local to global inductive approach to basic concepts in Geosciences • The construction of an open framework to stimulate creativity The project has been developed as an educational activity for secondary schools (11 to 18 years old students). It provides for the creation of a network of institutions to be involved in order to ensure the required diversified expertise. They can comprise: Universities, Natural Parks, Mountain Communities, Municipalities, schools, private companies working in the sector, and so on. A single project lasts for one school year (October to June) and requires 8-12 work hours at school, one or two half day or full day excursions and a final event of presentation of outputs. The possible outputs comprise a pdf or ppt guidebook, a script and a video completely shooted and edited by the students. The framework is open in order to adapt to the single class or workgroup needs, the level and type of school, the time available and different subjects in Geosciences. In the last two years the two parts of the project have been successfully tested separately, while the full project will be presented at schools in in its full form in April 2016, in collaboration with University of Milan, Campo dei Fiori Natural Park, Piambello Mountain Community and Cunardo Municipality. The production of geotube outputs has been tested in a high school for three consecutive years. Students produced scripts and videos on the following subjects: geologic hazards, volcanoes and earthquakes, and climate change. The excursions have been tested with two different high schools.

    In domestic applications the low DC output voltage of a hydrogen fuel cell used as the main power supply or a backup power source has to be matched to the level and frequency of the AC voltage of utility grid. The interfacing power converter system usually consists of a DC/DC converter and an inverter. In this work, a DC/DC step-up converter stage is designed for interfacing a 5kW proton exchange membrane (PEM) fuel cell. The losses of DC/DC conversion are estimated and, basing on the relevant analysis, the most appropriate configuration of converter modules is selected for a DC/DC converter stage of increased efficiency. The authors present the results of experimental analysis and simulation for the selected configuration of four double inductor step-up push-pull converter modules Ūdeņraža degvielas elementa invertoru sistēmas mājsaimniecības pielietojumiem parasti sastāv no līdzsprieguma paaugstināšanas un invertēšanas mezgliem.

  20. Role of vegetation on erosion processes: experimental investigation

    NASA Astrophysics Data System (ADS)

    Termini, Donatella

    2014-05-01

    Investigations on soil-system ecology are ever more oriented toward quantitative information based on the study of the linkages between physical processes and ecological response in rivers. As it is known, in presence of vegetation, the hydrodynamics characteristics of flow are principally determined by the mutual interrelation between the flow velocity field and the hydraulic behavior (completely submerged or emergent) of the vegetation elements. Much effort has been made toward identifying the theoretical law to interpret the vertical profile of flow longitudinal velocity in vegetated channels. Many theoretical and experimental studies in laboratory channels have been carried out and especially the case of submerged flexible vegetation has been examined (Termini, 2012). The effects of vegetation on flow velocity are significant and of crucial importance for stabilizing sediments and reducing erosion. Vegetation has a complex effect on walls roughness and the study of the hydrodynamic conditions of flow is difficult. Although most studies based on the "boundary layer" scheme so that the hydrodynamic conditions inside and above the vegetated layer are considered separately, some authors (Ghisalberti and Nepft, 2002; Carollo et al., 2008) claim that the "mixing layer" scheme is more appropriate to define the velocity profile both inside and outside the vegetated layer. Experimental program has been recently carried out in two laboratory flumes constructed at the laboratory of Dipartimento di Ingegneria Civile, Ambientale, Aerospaziale, dei Materiali - University of Palermo (Italy) with real and flexible vegetation on the bed. In this paper, attention is paid to the influence of vegetation on the erosion processes both on the bed and on the channel banks. The structure of the detailed flow velocity field is analyzed and compared with that obtained in absence of vegetation. Attention is then devoted to the analysis of soil erosion mechanism.

  1. A critique of the evidence for scavenging by Neanderthals and early modern humans: new data from Kobeh Cave (Zagros Mountains, Iran) and Die Kelders Cave 1 layer 10 (South Africa).

    The primary mode of faunal exploitation by Neandertals and early modern humans remains a debated topic. Binford (1981, 1984, 1985, 1988) has argued for an obligate scavenging mode, Stiner (1991a, 1991b, 1991c, 1993, 1994) for a more opportunistic scavenging mode, while other researchers (Chase, 1986, 1988, 1989; Klein, 1989, 1994, 1995; Klein & Cruz-Uribe, 1996) deny the importance of scavenging as a faunal exploitation tactic. The scavenging interpretations rely primarily on several patterns in the faunal remains: the presence of a skeletal element pattern dominated by heads or head and foot parts, the presence of carnivore tooth marks on bone fragments, and infrequent cut marks that typically are not located on shaft regions of long bones or on fleshy bones. Five sites have been used to argue for scavenging: Klasies River Mouth, Combe Grenal, Grotta Guattari, Grotta dei Moscerini, and Grotte Vaufrey. The former four of the five sites are biased samples in that long bone shafts and other difficult to identify fragments were discarded at excavation. The analysis of Grotte Vaufrey included only those shafts identifiable to species or genus, thus excluding the vast majority of shaft specimens. This bias systematically shapes the skeletal element and surface modification patterning in ways that make the assemblages appear to fit a model of scavenging, when in fact the main determinant of the pattern is the bias in the flawed samples. This problem is illustrated with two unbiased faunal assemblages (Kobeh Cave and Die Kelders Layer 10). Skeletal element abundance is calculated in a way that mimics the bias in the sites listed above by excluding the shafts. Using this procedure, both Kobeh and Die Kelders have a head and foot skeletal element pattern and thus appear scavenged. Both assemblages are then analyzed in their entirety and a new pattern, consistent with hunting, is revealed. Taphonomic data on bone survival and destruction provide an explanation for this

    2003-04-01

    A paleobathymetric reconstruction, based on the integrated study of both foraminiferal assemblages and red-algal concretions (rhodoliths), has been carried out for the Venetian Foothill succession cropping out along the southern border of the Alpine chain (Veneto-Friuli Foreland System, NE Italy). The studied succession, up to 500 m thick, has been deposited into a shallow to deep water marine environment during the Aquitanian to Langhian time-interval, due to the combined effect of the Dinaric and Alpine tectonics and the eustatic sea-level changes. The main goals of this work are: i) to reconstruct the paleobathymetry of the Venetian foothill succession and, tentatively, ii) to relate the bathymetric evolution of the studied areas to the sea-level changes and to the history of the vertical motion ("geohistory") of the underlying substratum in response to tectonics and sedimentary load. The detected time-interval (Aquitanian to Langhian) is particularly important as it embraces the transition between the Dinaric and South-Alpine orogenetic phases. The main results can be summarised as follows: a paleobathymetric evolution has been observed for the studied succession from the Aquitanian to the Langhian. In particular a 40--60 m paleodepth has been determined for the Calcareniti di Castelcucco Fm. Moreover a peculiar depositional environment, such as an outer-shelf incised by submarine canyons and characterised by a relatively high water hydrodynamism, has been proposed for this formation on the basis of the rhodolith size (5--6 cm). An upper to lower neritic depth (from 0--100 to 100--200 m) has been obtained for the Siltiti dei Casoni and Arenarie di Libano Formations and for the Marne di Monte Bolago Fm., respectively. An upper bathyal depth (200--600 m) has been determined for the lower-middle part of the Marne di Monfumo Fm. Finally a gradually decreasing in depth has been observed, in particular a lower to upper neritic paleodepth (from 200--100 to 100--0 m

    Vito Graziano, Gian

    2013-04-01

    The development of a society in economic, cultural and ethical terms is always linked to the growth of the scientific and technical knowledge. It follows that the downsizing of the scientific research brings to a slower growth or even, as it is happening these days in Italy, a real cultural decay. The consequences of the economic crisis are evident to everyone, but it is precisely in times of crisis that the best strategies to restart the economy and give new cultural perspectives to society are studied. The crisis is also contrasted with ideas and ability to put them into practice. This, however, also presupposes a different cultural approach, which has to also include a review of values and beliefs, and a redefinition of the objectives to be pursued. This approach is modeled on the basis of several positive experiences that a country can boast. Among these experiences, there are those arising from the scientific culture: geology, for example, such as chemistry, biology or other sciences, can help to change vision. The research and practice of Earth sciences have important implications on the life and activities of the population and therefore the geoscientists, as active subjects in the society, should question their role and responsibilities. They should be at the service of society, especially in the fields of prevention from natural hazards and valorization of georesources. In this sense they can give important indications for economy and development of their country. The Italian Council of Geologists (Consiglio Nazionale dei Geologi - CNG) acts with the aim of highlighting the social role of geoscientists, hoping for a new cultural Renaissance, which leads to new researches, without obscurantism or prejudices. In an authoritative way, the CNG intends to put this social role before any demand from the professional category. Therefore, it has recently presented its political Manifesto, geared essentially to the good governance of the territory, to all the

    This work presents the GIIDA (Gestione Integrata e Interoperativa dei Dati Ambientali del CNR) inter-departimental project of the Italian National Research Council (CNR). The project is an initiative of the Earth and Environment Department (Dipartimento Terra e Ambiente) of the CNR. GIIDA mission is "To implement the Spatial Information Infrastructure (SII) of CNR for Environmental and Earth Observation data". The project aims to design and develop a multidisciplinary cyber-infrastructure for the management, processing and evaluation of Earth and environmental data. This infrastructure will contribute to the Italian presence in international projects and initiatives, such as: INSPIRE, GMES, GEOSS and SEIS. The main GIIDA goals are: • Networking: To create a network of CNR Institutes for implementing a common information space and sharing spatial resources. • Observation: Re-engineering the environmental observation system of CNR • Modeling: Re-engineering the environmental modeling system del CNR • Processing: Re-engineering the environmental processing system del CNR • Mediation: To define mediation methods and instruments for implementing the international interoperability standards. The project started in July 2008 releasing a specification document of the GIIDA architecture for interoperability and security. Based on these documents, a Call for Proposals was issued in September 2008. GIIDA received 23 proposed pilots from 16 different Institutes belonging to five CNR Departments and from 15 non-CNR Institutions (e.g. three Italian regional administrations, three national research centers, four universities, some SMEs). These pilot were divided into thematic areas. In fact, GIIDA considers seven main thematic areas/domains: • Biodiversity; • Climate Changes; • Air Quality; • Soil and Water Quality; • Risks; • Infrastructures for Research and Public Administrations; • Sea and Marine resources Each of these thematic areas is covered by a

Data l'influenza della fragilità sulla relazione tra pressione arteriosa e mortalità, il clinico dovrebbe avvalersi di adeguati strumenti per la definizione di performance fisica e cognitiva ed il monitoraggio nel tempo, mirando ad un target di pressione arteriosa sistolica compreso tra 130 e 150 mmHg. Rischi e benefici della terapia antiipertensiva dovrebbero essere attentamente valutati prima di intraprendere un trattamento, data la possibilità di eventi correlati sia all'ipertensione che all'ipotensione e la frequente coesistenza di ipotensione ortostatica, che incrementa il rischio di eventi sincopali e cadute. Nell'anziano iperteso con storia di sincope e cadute il trattamento dovrebbe quindi essere intrapreso una volta confermata la diagnosi, mirando ad un target pressorio più contenuto e con una scelta ponderata dei principi attivi.

    paradosso potrebbe essere spiegato dal fatto che spesso, in passato, per ottenere un miglioramento glicometabolico si sono utilizzati farmaci ipoglicemizzanti in grado di aumentare il rischio ipoglicemico, la variabilità glicemica ed il peso corporeo. In conclusione, il miglioramento del compenso glicemico, specie nel paziente anziano, dovrebbe essere ottenuto, quando possibile, con farmaci a basso rischio ipoglicemico e non inducenti aumenti di peso, per evitare gli effetti negativi di ipoglicemie e eccessive fluttuazioni della glicemia che di per sé costituiscono dei fattori di rischio cardiovascolari al pari dell'iperglicemia. In questo articolo, si esplorerà l'ipotesi che iperglicemia, ipoglicemia e variabilità glicemica costituiscano una triade fatale in grado di aumentare morbilità e mortalità nei pazienti affetti da diabete mellito.

    Canova, G. M.

    2011-06-01

    In the Middle Ages, the University of Padua was one of the most prominent centre for astrological studies in Europe. The Paduan doctor and philosopher, Pietro d'Abano, who lived in the first decades of the 14th century, was the main figure in this field. At the end of the 13th century, during a long stay in Paris, he got in contact with the new astrological doctrines flourished after the translation into Latin of Ptolemy's and Arab's works in Spain. Thus, when he went back to Padua, he published several studies on the influence of celestial bodies on human life and human physical characteristics and psychology. These ideas deeply affected the Paduan society of the 14th century and, consequently, the most important painters chose or were asked to evoke the images of stars, planets, and their properties. This adventure began with Giotto who shows a surprising interest in celestial bodies in the Scrovegni Chapel where he represented a comet, and soon after he produced a cycle of astrological paintings on the vault of the Palazzo della Ragione in the Public Palace of Padua. Unfortunately, in 1420, these paintings were destroyed in a fire, but the magnificent cycle of astrological frescoes realized soon after on the walls of the same room gives us some clues on Giotto's work and shows us the complexity of the Medieval astrological science. Other astrological paintings, still preserved, were realized by the painters of the Carrarese Court such as Guariento, who painted the planets and their influences on human ages in the church of the Eremitani, and Giusto dei Menabuoi who represented a superb zodiac around a realistic map of Earth in the Cathedral Baptistery. So Padua really became the capital of astrological painting in Europe. Other evidence of the astrological image in the Veneto Region, between the 14th and 15th centuries, can be found in the manuscripts illuminated in the milieu of the University of Padua and in the first books printed in Venice.

  13. A TRANSPORTATION RISK ASSESSMENT TOOL FOR ANALYZING THE TRANSPORT OF SPENT NUCLEAR FUEL AND HIGH-LEVEL RADIOACTIVE WASTE TO THE PROPOSED YUCCA MOUNTAIN REPOSITORY

    2001-02-15

    The Yucca Mountain Draft Environmental Impact Statement (DEIS) analysis addressed the potential for transporting spent nuclear fuel and high-level radioactive waste from 77 origins for 34 types of spent fuel and high-level radioactive waste, 49,914 legal weight truck shipments, and 10,911 rail shipments. The analysis evaluated transportation over 59,250 unique shipment links for travel outside Nevada (shipment segments in urban, suburban or rural zones by state), and 22,611 links in Nevada. In addition, the analysis modeled the behavior of 41 isotopes, 1091 source terms, and used 8850 food transfer factors (distinct factors by isotope for each state). The analysis also used mode-specific accident rates for legal weight truck, rail, and heavy haul truck by state, and barge by waterway. This complex mix of data and information required an innovative approach to assess the transportation impacts. The approach employed a Microsoft{reg_sign} Access database tool that incorporated data from many sources, including unit risk factors calculated using the RADTRAN IV transportation risk assessment computer program. Using Microsoft{reg_sign} Access, the analysts organized data (such as state-specific accident and fatality rates) into tables and developed queries to obtain the overall transportation impacts. Queries are instructions to the database describing how to use data contained in the database tables. While a query might be applied to thousands of table entries, there is only one sequence of queries that is used to calculate a particular transportation impact. For example, the incident-free dose to off-link populations in a state is calculated by a query that uses route segment lengths for each route in a state that could be used by shipments, populations for each segment, number of shipments on each segment, and an incident-free unit risk factor calculated using RADTRAN IV. In addition to providing a method for using large volumes of data in the calculations, the

    Ceres is the largest object in the asteroid belt between Mars and Jupiter, and it was discovered on January 1, 1801, by the Italian astronomer Giuseppe Piazzi. The study of Ceres is especially relevant to my students because this celestial body was discovered in Palermo, in the astronomic observatory located in the UNESCO world heritage site "Palazzo dei Normanni", around 500 meters away from the institute where I teach, and because Ceres was considered the patron goddess of Sicily. Moreover, it received scientists and media attention recently because it was explored by the NASA Dawn spacecraft in 2015. The categorization of Ceres has changed more than once and has been the subject of some disagreement. It was originally considered a planet, but was reclassified as an asteroid in the 1850s when many other objects in similar orbits were discovered. Its status changed again in 2006 when it was promoted to dwarf planet, a classification it shares with Pluto and other Kuiper belt objects. The study of this celestial body has a notable educational value, since the uncertain identity of Ceres constitutes an occasion to reflect on the criterions of classification of the natural objects. The history of its discovery allows the students to understand as the scientific method doesn't always consist in the verification of hypothesis through experiments but it sometimes asks for the forecast of facts through mathematical calculations, repeated and methodic observations, the collaboration between scientists of different sectors and nationality. Furthermore, it is a particularly suitable topic for interdisciplinary connections, as regards both scientific and humanistic matters. In order to promote the scientific competences of my first class students, I have developed a learning unit on Ceres, thanks to good cooperation with the Palermo Observatory scientists, particularly active in the astronomic dissemination towards the schools and the citizens.

    This paper, by means of a multidisciplinary approach, deals with changes of the urban and territorial setting in many localities of the epicentral area of the 23 November 1980 Irpinia earthquake. The 23 November 1980 earthquake, known as the "Irpinia-Basilicata earthquake" was the strongest seismic event of the last 80 years in the Southern Apennines of Italy (Mw 6.9, I0=X MCS). It was felt nearly everywhere in Italy, from Sicily in the South, to Emilia Romagna and Liguria in the North. This earthquake was characterized by a complex main rupture, composed of three major sub-events, interpreted as a succession of normal faulting events. Many localities in the Avellino, Salerno and Potenza provinces were nearly completely destroyed (I=IX-X MSK, Postpischl et al., 1985); among them Castelnuovo di Conza, Conza della Campania, Lioni, Santomenna, San Mango sul Calore, San Michele di Serino and Sant'Angelo dei Lombardi. About 800 localities suffered serious damage (Balvano, Bisaccia, Calitri, etc); 75,000 houses collapsed totally and 275,000 were badly damaged. Casualties were 3000, and 10,000 people were wounded. A large amount of information on primary and secondary environmental effects, over all slope movements, was available on the basis of several geological surveys of the area affected by this earthquake. The amount of surface faulting was about 40 km in length and the maximum displacement about 100 cm, while the total area interested by slope movements was estimated in 7400 km2 (Porfido et al., 2002, 2007; Serva et al.2009). In this study we aim to describe trends and specific effects that have taken place in the 35 years following the 1980 earthquake: how the urban and territorial setting have changed, especially in the villages located in the epicentral area; the consequences of the environmental effects on the choices of reconstruction, both in situ, and far from the original historical centre. Therefore, some case histories as San Mango sul Calore and Calitri

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).

    training dataset of occurrences and a test dataset, a cross validation is made. The valuation both for flows and slides was performed through Prediction Rate Curves (PRC). By utilising the occurrences of the test dataset, PRC derived from the relation between CF trend in the whole area (cumulative percentage), portion of total area and number of landslides. As result, engineering geology can be indicated as the dominant factor for PRC of flows; likewise engineering geology, land use and RBS combination is the more effective combination. On the other side, slope and aspect resulted less determinative in best PRC trend. Moreover, the combination of engineering geology and slope allowed the computation of best PRC for landslide.

    Italy is an earthquake-prone country with a long tradition in observational seismology. For many years, the country's unique historical earthquake record has revealed fundamental properties of Italian seismicity and has been used to determine earthquake rates. Paleoseismological studies conducted over the past 20 years have shown that the length of this record - 5 to 8 centuries, depending on areas - is just a fraction of the typical recurrence interval of Italian faults - consistently larger than a millennium. Hence, so far the earthquake potential may have been significantly over- or under-estimated. Based on a clear perception of these circumstances, over the past two decades large networks and datasets describing independent aspects of the seismic cycle have been developed. INGV, OGS, some universities and local administrations have built networks that globally include nearly 500 permanent GPS/GNSS sites, routinely used to compute accurate horizontal velocity gradients reflecting the accumulation of tectonic strain. INGV developed the Italian present-day stress map, which includes over 700 datapoints based on geophysical in-situ measurements and fault plane solutions, and the Database of Individual Seismogenic Sources (DISS), a unique compilation featuring nearly 300 three-dimensional seismogenic faults over the entire nation. INGV also updates and maintains the Catalogo Parametrico dei Terremoti Italiani (CPTI) and the instrumental earthquake database ISIDe, whereas OGS operates its own seismic catalogue for northeastern Italy. We present preliminary results on the use of this wealth of homogeneously collected and updated observations of stress and strain as a source of loading/unloading of the faults listed in the DISS database. We use the geodetic strain rate - after converting it to stress rate in conjunction with the geophysical stress data of the Stress Map - to compute the Coulomb Failure Function on all fault planes described by the DISS database.

These were covered in sessions devoted sequentially to viscous flow and microscopic relaxation, theoretical aspects, numerical simulation, rheology, glassy materials, confined materials, heterogeneities and energy landscape, polymers, and ageing. Three poster sessions further dealt with the above subjects. The structure of the workshop has been preserved in this publication, in which the set of papers from the plenary lectures is followed by topical contributions in the order in which they were presented. Five contributions to the proceedings come from a selection of the posters. The proceedings end with the round table contributions. We wish here to thank all participants in the workshop, who made it enjoyable and scientifically profitable, and all referees who worked in preparing this special issue of the Journal of Physics: Condensed Matter. We also wish to acknowledge the generous support that we have received from our institutions and the sponsorship and support given by the Istituto Nazionale di Fisica della Materia and by its section Fisica dei Liquidi e Sistemi Disordinati. The Cassa di Risparmio di Pisa hosted the workshop in the splendid location provided by the Convento delle Benedettine. On the behalf of the international scientific community we express our gratitude to all these institutions as well as to those individuals-we mention here in particular Dr Massimo Faetti, Dr Diego Palazzuoli, Dr Fabio Zulli, Ms Beatrice Pistoresi and Ms Patrizia Pucci-who have contributed to organizing and running the workshop.

    , especially for low canal discharge, because of the high instrumental error. A more rigorous method, based on the quantification of artificial tracers mass losses through exfiltration, was tested. This methodology is based on QUEST method (Rieckermann J. & Guier W., 2002; De Luca et alii, 2012). The used tracers were sodium chloride (NaCl), uranine and rhodamine WT. Uranine and rhodamine were detected by means of a fluorometer and NaCl thanks to a conductivimeter. In order to reduce the error of the NaCl detection, a multistage sampling in different parts of the cross section was applied, guaranteeing the contemporary water picking up. The results of these last tests were more accurate and in accordance with the aim of the research. References De Luca D.

    square kilometers. Its movement towards NW produced a typical coastline, with a strong progradation towards NW and W from Punta della Tonnara to Parghelia and up to Fiumara della Ruffa (WSW of Tropea). The DSGSD involves the granitic bedrock as well as the transgressive Tortonian deposits, made by sands with the presence of Clypeasters, which are topped by arenaceous banks, for a total depth of 150 m. DSGSDs involving granitic rocks were probably due to more deformable lithotypes, like biotite schists, which work as substratum of granitic rocks at a not very deep depth, like in other areas of Calabria. Finally, the slow sliding towards N and NW of the landslide shapes the coast like a bow, thus causing strong erosion phenomena of the coastline. Ietto A & Calcaterra D. (1988).

    2012-04-01

    The well-known genus Nummulites flourished in the stable, oligotrophic environments of Eocene. During this time, peculiar monospecific accumulations called nummulite banks (Arni, 1965) developed. The paleoenvironmental interpretation of these banks is still debated. So far, several studies deal with nummulite banks but their quantitative aspects were neglected. Here we present new quantitative observations useful to better define the nummulite bank concept. Samples were collected from Pederiva di Grancona (N. lyelli bank) and San Germano dei Berici (N. fabianii bank; both in the Berici Mts., northern Italy). According to the Shallow Benthic Zonation of Serra Kiel et al. (1998) the Pederiva bank is referred to the SBZ 17 (Early Bartonian), and the San Germano bank to the SBZ 19 (Early Priabonian). In both cases there is a bimodal grain size distribution of microspheres and megalospheres of Nummulites in a fine-grained matrix, giving rise to a packstone texture. In Pederiva, 1448 Nummulites isolated specimens (A-forms) were counted and identified at the species level. Among them 1082 individuals are Nummulites lyelli, so 74.7% of the identified assemblage. Nummulites striatus is the second most-abundant species with the 11.5%, and the rest are the three accessory species N. discorbinus, N. biarritzensis, N. beaumonti. In the San Germano bank, 2043 isolated A-forms of Nummulites were counted and identified at the species level. Among them, 1742 are Nummulites fabianii, which means 85.3% of the assemblage. The second most-abundant species is Nummulites stellatus, accounting for 10.6% of the assemblage. The rest of the assemblage is made by small, lenticular Nummulites (N. incrassatus, N. chavannesi, N. cunialensis and N. garnieri). On polished surfaces of two samples from San Germano and Pederiva, two areas (38 and 76 cm2 respectively) were observed to count all the visible specimens of Nummulites in order to calculate the A/B ratio. The "normal" A/B ratio usually

    The Bouvante meteorite, a single stone weighing 8.3 kg, was found on 30th July 1978 and has been classified as a mononict recrystallized eucrite by Michel Levy et al. (1987). Here are the results of measurements of cosmic ray track density and radioisotopes ^26Al, ^22Na, and ^44Ti in a 700-g fragment taken from the main mass. Track Density: Four samples for track density measurements were taken from the farthest corners of the 700-g fragment and feldspars were etched in boiling 1:2 NaOH for 60 minutes. Track density in different fragments ranged between 3.1 X 10^4 to 2.7 X 10^5 tracks/cm^2 showing some gradient within the fragment. The exposure age of Bouvante has been determined from ^21,22Ne and other rare gases that yield values between 5.6 and 6.7 Ma (Weber et al., 1983). Adopting a value of 6 Ma leads to track production rate of 5 X 10^3 to 4.5 X 10^4 tracks/cm^2 Ma corresponding to ablation ranging between about 18 and 9 cm. If the mean value of 13.5 cm is taken as representative ablation then Bouvante had a pre-atmospheric radius of ~21 cm. Cosmogenic Radionuclides: Gamma ray emitters were measured by whole-rock counting with a low background gamma-ray spectrometer. A high purity, 372 cm^3, coaxial Ge diode located within a 10-cm- thick active NaI(Tl) well scintillator in a 20-cm-thick lead shield, in the underground laboratory of Monte dei Cappuccini in Torino (Bonino et al., 1991) served as the gamma ray detector. The detector was used in two modes, in coincidence and in anticoincidence with the scintillator. The counting efficiency was determined by using the inherently present ^40K as an internal standard and by calibrating the detector at different energies. K in Bouvante is known to be 610 ppm (Michel Levy et al., 1987). The sensitivity and selectivity of the detector is high and the background extremely low so that, in addition to the long lived ^26Al, 48-yr ^44Ti which is produced at very low levels and 2.6-yr ^22Na could be measured even after lapse

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

    lower limit, sets respectively at 2590 m a.s.l. and 2200 m a.s.l. for intact and relict types. The majority of the inventoried landforms sits within the 2000-2500 m (53 %) and 2500-3000 m (39%) elevations belts. In order to explore potential lithologic controls on rock glacier abundance, we calculate surface ratios across major lithological categories. This attribute for a given lithology is the ratio between the combined surface of the inventoried landforms and the relevant terrain surface over the 1460 m a.s.l. (i.e. minimum elevation of the lowest relict rock glacier). Higher rock glacier densities are found in intrusive (0.032) and metamorphic (0.031) rocks, followed by extrusive (0.017) and sedimentary ones (0.012). This inventory represents a necessary preliminary step for modelling the spatial distribution of permafrost at the regional scale. We believe the inventory integrates well with prior and ongoing research on the cryosphere of the Alps. In particular, our research effort fills a strategic geographic gap in the context of the PermaNET initiative. - Cremonese, E., Gruber, S., Phillips, M., Pogliotti, P., Boeckli, L., Noetzli, J., Suter, C., Bodin, X., Crepaz, A., Kellerer-Pirklbauer, A., Lang, K., Letey, S., Mair, V., Morra di Cella, U., Ravanel, L., Scapozza, C., Seppi, R., and Zischg, A. 2011, Brief Communication: "An inventory of permafrost evidence for the European Alps", The Cryosphere Discuss., 5, 1201-1218. - Scapozza, C., Mari, S. 2010, Catasto, caratteristiche e dinamica dei rock glaciers delle Alpi Ticinesi.

    The GIIDA (Gestione Integrata e Interoperativa dei Dati Ambientali) project is an initiative of the Italian National Research Council (CNR) launched in 2008 as an inter-departmental project, aiming to design and develop a multidisciplinary e-infrastructure (cyber-infrastructure) for the management, processing, and evaluation of Earth and Environmental resources -i.e. data, services, models, sensors, best practices. GIIDA has been contributing to the implementation of the GEO (Group of Earth Observation) Science and Technology (S&T) roadmap by: (a) linking relevant S&T communities to GEOSS (GEO System of Systems); (b) ensuring that GEOSS is built based on state-of-the-art science and technology. GIIDA co-ordinates the CNR's digital infrastructure development for Earth Observation resources sharing and cooperates with other national agencies and existing projects pursuing the same objective. For the CNR, GIIDA provides an interface to European and international interoperability programmes (e.g. INSPIRE, and GMES). It builds a national network for dialogue and resolution of issues at varying scientific and technical levels. To achieve such goals, GIIDA introduced a set of guidance principles: • To shift from a "traditional" data centric approach to a more advanced service-based solution for Earth System Science and Environmental information. • To shift the focus from Data to Information Spatial Infrastructures in order to support decision-making. • To be interoperable with analogous National (e.g. SINAnet, and the INSPIRE National Infrastructure) and international initiatives (e.g. INSPIRE, GMES, SEIS, and GEOSS). • To reinforce the Italian presence in the European and international programmes concerning digital infrastructures, geospatial information, and the Mega-Science approach. • To apply the National and International Information Technology (IT) standards for achieving multi-disciplinary interoperability in the Earth and Space Sciences (e.g. ISO, OGC

  12. The importance of geoethics in the "Land of Fires"

    2014-05-01

    How was it possible that one of the most fertile soil worldwide called by Romans "Campania Felix", became one of the largest mass poisoning in a Western country? Answer is in the tons of toxic wastes illegally dumped into the fields all around area between Naples and Caserta, which now is known as "Terra dei Fuochi" (The Land of Fires - due to illegal wastes burning). In last 25 years two main emergencies affected Campania, one official started in 1994 due to local waste management system problems, another more hidden and older due to criminal gangs which earn money by illegal disposal of toxic wastes. Those two emergencies are interconnected and have grown in absence of respect for people's health and unknowledge of environmental themes. Apart from judging legal issues, the only evidence visible to public opinion is that during waste emergencies in Campania, decision makers, admitting also their good faith, didn't consider enough environmental risks and decided, in order to solve emergency, to dump wastes in not geological feasible sites, such as landfills at the feet of Vesuvio national park or in abandoned quarries such as Chiaiano tuff pit, exposing local inhabitant and economic activities to high risks. This work wants to underline that geoethics is fundamental as much as the need of geologists participation to whole remediation processes and to raising environmental awareness in the society. Maybe these themes seems to be trivial but geological competences are very important in understanding of pollution risks. This knowledge is practically obscure to decision makers and people, often media provides uncorrected informations which improve the fear of population. In example the idea that whole groundwater in the area is polluted is wrong and is strongly reducing the purchase of agricultural products of the area, and the only way to assess real contamination is site-specific characterization. Indeed Campania plain has a complex stratigraphic architecture with

    Protection, and also documents belonging to a research project (PS_119; Cotecchia et al. 2010). According to the landslide data collected, the landslide events resulted to be 175 in the study area. The trend analyses show that the landslide occurrence was increased with the time, despite of the rainfall and temperature data are not prone to landsliding. As a matter of fact, the trend of both the monthly rainfall and the rainfall intensity decreases, and the temperature and the wet days show a positive trend during the period of reference. The trend of the short-duration rainfall results generally to decrease. Not existing an evident relationship between climate variability and the increase of landslide occurrence, some other factors should be considered, as, for instance, the poor mechanical soil properties, the role of anthropogenic modifications and the mismanagement of risk-prone areas. In this regards, the preliminary results obtained from the data analyses of the land use and the populations could partly justify the increasing trend of landslide occurrence. More details on previous results of this research activity were recently published (Cotecchia et al., 2010; Polemio and Lonigro, 2011 and 2013; Santaloia et al., 2012).

    Bioreactor landfilling, with the acceptance of landfill Directive 1999/31/EC has lost its actuality in European Union; at the same time, this method can still be used for acceleration of biowaste degradation and biogas production. One of the possibilities to reduce the disposal of biowaste is to use biocells for its anaerobic pre-treatment before landfilling. The daily filling up of such a cell requires isolation of the main volume to limit gas emissions, reduce smells, etc. Bioprocesses that are of the utmost importance for biocell treatment are often not taken into account in selection of materials to be used as daily landfill covers. Based on physical, chemical and biological methods the investigations have been carried out into different covering materials offered in the market, with identification of parameters that are the most important for daily covering the biocells. It is found that the materials fitted best this purpose should be of biological origin and consist of small bio-particles with large surface, without the inhibitors of anaerobic processes such as sulphuric compounds. Bioreaktoru pielietošana atkritumu uzglabāšanas sfērā, sakarā ar Direktīvas 1999/31/EC pieņemšanu, ir zaudējusi savu aktualitāti, taču šī metode vēl joprojām var tikt izmantota bioatkritumu noārdīšanai un biogāzes ražošanai.

    The paper presents an integrated multidisciplinary approach to the morphometric and morphotectonic characterization of the Cannobino Basin (Piemonte Region, NW-Italy). The basin is drained by the Cannobino river; in its first 8 km, it flows SE to NW along a wide valley characterized by glacial landforms; thereafter it suddenly turns South assuming a W to E direction, by flowing in a deeply entrenched valley to the intermontane basin of the Maggiore Lake. This area belongs to the Lepontine Alps, which from the geological point of view belong to the Southern Alps. His Hercynian basement is divided in two units: Ivrea-Verbano Zone (IVZ) and Serie dei Laghi (SDL). The IVZ outcrops in the northern sector of the basin, while the SDL outcrops in the southern and central sector. They separated by the Cossato-Mergozzo-Brissago (CMB) and Pogallo lines (PL). These major discontinuities and the neoctonic activity of their shear zones possibly control Quaternary evolution of the alpine relief. Detailed studies of the area are needed for understanding possible interactions of neotectonic activity, fluvial/glacial erosional/depositional processes and slope dynamics. Our focus is on drainage basin characteristics and its evolutionary stages in response to local and regional base level changes and to differential rock uplift. GIS methodologies combined with DEMs analyses are among the most common geomatics approaches to geomorphology. Based on this framework, an evaluation of the geomorphometric characteristic of the Cannobino Basin has been carried out by using an aerial LIDAR DEM (5x5 meters, Regione Piemonte, 2009). The workflow followed for calculating the geomorphic indexes can be summarized in different steps: i) drainage network extraction and hierarchization; ii) lineament features digitalization and interpretation; iii) azimuthal distribution of drainage pattern; iv) DEM analysis and evaluation of linear, areal indexes and SWAT profile.

He isotope ratios are radiogenic with only minor mantle contributions, as it is typical for the Western Alps (Marty et al., 1992).

In order to test the system and the automatic processing routines needed in order to process a huge amount of data, several surveys have been preformed on few roads affected by landslides. The results of the GPR mobile system have been compared and integrated with the outcomes of surveys performed by a GSSI SIR 3000 System with a 400 MHz ground coupled antenna so to achieve information about the section of the road to depths significant for a reliable monitoring and in this work some acquisition examples are described and discussed.

    Ground-penetrating radar has been increasingly played an important role over the last 15 years in Italy due to its high reliability in assisting the assessment of the built environment for civil engineering purposes, and in being used for geophysical investigations within many other fields of application. In line with this, original works involving fundamental aspects of this technique and implementing its use more practically in a number of interesting projects have been developed over years, both under a research and an enterprise point of view. This paper will endeavour to review the current status of ground-penetrating radar activities in Italy. Efforts have been devoted to single out the most interesting national research projects, both recent and ongoing, involving ground-penetrating radar in Italy, such as the ARCHEO project in the 90s, funded by the Italian Ministry for Universities, wherein a stepped frequency ultra-wide band radar suited for archaeological surveys was manufactured. In this framework, it is worth citing another important and more recent project, European Community funded, namely, ORFEUS, which started in the late 2006 with the overall aim of providing the capability to locate buried infrastructure accurately and reliably by means of a bore-head ground-penetrating radar for horizontal directional drilling. A review on the main use of this non-destructive technique in management activities of national resources and infrastructures has been also performed, ranging from the applications made by Anas S.p.A., i.e., the main management authority for the Italian road and motorway network, up to private enterprises specialized in both services providing and ground-penetrating radar manufacturing such as, to cite a few, Sineco S.p.A. and IDS Ingegneria dei Sistemi S.p.A., respectively. Current national guidelines, rules or protocols to be followed during radar surveys have been also reviewed. Unlike well-established international standards such as

    The rheology of the Earth's crust is ultimately a function of the properties of its constituent minerals. Nowhere are the results of applied tectonic stresses within the Earth's crust more evident than along large scale fault zones and shear zones where strains become focussed producing localised deformation and displacement. These dynamic tectonic discontinuities are often dominated by fault rocks and mylonites that contain an abundance of phyllosilicates (such as micas) whose inherent weakness, relative to other silicate phases (Mariani et al. 2006), acts to concentrate deformation along these narrow regions. Experimental studies show that even in rocks where the concentration of weak phases, such as micas, is low, their effect on the strength and fabric of the rock is significant due to processes such as strain-induced interconnectivity (Holyoke & Tullis 2006). Once this interconnectivity has been established, very high strains can be accommodated within very narrow regions, termed shear bands or micro-shear zones. In this study, a combination of optical and scanning electron microscope (SEM) based techniques including electron backscatter diffraction (EBSD) have been used to observe and document features that are indicative of such processes within samples collected from the Cossato-Mergozzo-Brissago (CMB) shear zone in North Western Italy. This tectonic discontinuity is interpreted to be of Permian age and separates the metapelitic schists of the Kinzigite formation of the lower crustal Ivrea-Verbano zone from the mid-crustal schists and amphibolites of the Serie dei Laghi. Despite its present vertical attitude, the CMB line is believed to have formed as a gently inclined, mid-crustal shear zone during the early stages of post-Hercynian crustal stretching (Rutter et al. 2007). This has produced mylonites composed predominantly of quartz, feldspar and abundant phyllosilicates which serve as perfect natural examples on which to study the distribution of micas

    This work is part of a research on the use of terrestrial laser scanner, integrated with total station and GPS, for the documentation and comprehension of complex architectures in up-land sites. The research is performed in the framework of the project "Ambiente e Paesaggi dei siti di Altura Trentini" - APSAT (Environment and landscape of hill-top sites in Trentino), a multidisciplinary project focused on the evolution of hill-top anthropic system in the Trentino region, Italy. The study area is located in the Gresta Valley and this work concerns on the Nagià Grom site, fortified by the Austria-Hungarian Army during the World War I. The site has been interested by a significant restore operation of a large series of entrenches paths and fortifications in the last decade. The survey herein described has involved an area once interested by military barracks with Officers' Mess, water provision and by one of the biggest field kitchens discovered in the Trentino region. A second survey involved the tunnel connecting the ammunition depot to the artillery stations. The nature of such complex architectures, characterized by an irregular and composite 3D span leads, in general, to necessary simple surveys and representations and somehow to simplified studies too. The 3D point cloud, once filtered by the massive presence of dense vegetation, eventually constitutes a rich data set for further analyses on the spatial, geological, architectural and historical properties of the site. The analysis has been carried out on two different scales. At the architectural-scale, the comparison to historic photos has allowed to understand how the original structure of the barracks was made and to find building characters that now are lost. The on-site observation of the underground stratigraphic splices and their analysis in the 3D point cloud, e.g., spatial extension and slope, have permitted the understanding of the special excavation process guided by the practical advantage of

    The Sesia magmatic system from Ivrea-Verbano Zone (hereafter IVZ) comprises intrusive and volcanics rocks of Lower Carboniferous to Upper Permian age (Sinigoi et al., 2010), which are exposed in a virtually complete section across the pre-Mesozoic Adriatic continental crust. Intrusions are present at different stratigraphic levels. Gabbroic to dioritic rocks of the Sesia Mafic Complex intruded the granulite- to amphibolite-facies metasedimentary and metavolcanic rocks of the lower crust. Granitoid plutons are dominant in the adjacent intermediate to upper crustal sequence of the Serie dei Laghi, whose emplacement was accompanied by intermediate to acidic volcanism. Recent investigations have shown that the geodynamic evolution of the northernmost tip of the IVZ (Finero area) involved Triassic-Lower Jurassic magmatic episodes (Zanetti et al., 2013; Schaltegger et al., 2015), thereby suggesting the presence of important geological heterogeneities within IVZ. This presentation deals with the petrology and the geochemistry of the lower crust intrusions that are geographically intermediate between Sesia and Finero areas. We focus on the so-called Monte Capio sill, which is found near the deepest level of the exposed continental crust, close to the Insubric line. The sill is about 4 km long, spreading from Strona to Sesia valley, and has maximum thickness of 600 m. Peculiar characteristics of the Monte Capio sill are: (i) dominance of ultramafic rocks, and (ii) close association with garnet-bearing gabbros and granulite-facies SiO2-rich rocks ("stronalites"). U-Pb zircon geochronology returned ages spanning from 314.0 ± 5.2 to 283.2 ± 6.0 Ma, which were tentatively interpreted as crystallization and recrystallization ages, respectively (Klotzli et al., 2014). The Monte Capio sill mostly consists of amphibole-bearing peridotites to pyroxenites. The pyroxenites typically contain Fe-Ni-Cu mineralizations that were exploited in the past century through mine activity. In

    Protection, and also documents belonging to a research project (PS_119; Cotecchia et al. 2010). According to the landslide data collected, the landslide events resulted to be 175 in the study area. The trend analyses show that the landslide occurrence was increased with the time, despite of the rainfall and temperature data are not prone to landsliding. As a matter of fact, the trend of both the monthly rainfall and the rainfall intensity decreases, and the temperature and the wet days show a positive trend during the period of reference. The trend of the short-duration rainfall results generally to decrease. Not existing an evident relationship between climate variability and the increase of landslide occurrence, some other factors should be considered, as, for instance, the poor mechanical soil properties, the role of anthropogenic modifications and the mismanagement of risk-prone areas. In this regards, the preliminary results obtained from the data analyses of the land use and the populations could partly justify the increasing trend of landslide occurrence. More details on previous results of this research activity were recently published (Cotecchia et al., 2010; Polemio and Lonigro, 2011 and 2013; Santaloia et al., 2012).

As for case (ii), our ongoing analyses are aimed to analyze the tectonic "significance" of some closed depressions, up to 4 km long and to 0,5-1 km large, that occur along the south-western slope of the Gran Sasso Range. All these small depression are NW-SE trending. As already described by Bosi et al. (1989), Galadini and Giuliani (1993), D'Agostino et al. (1998), Falcucci et al. (2015), these closed depressions are bounded by scarps carved onto the carbonate bedrock and, subordinately, onto early Quaternary slope deposits, reaching height of up to 5 m. These scarps are preferentially NE dipping, even if in few cases some SW dipping scarp are also present . The field work has permitted to attest that these scarps are related to shear planes that that displaced two subsequent of Early Pleistocene breccias formations (the Valle Valiano Fm. and Fonte Vedice Fm.; Bosi e Bertini, 1993; D'agostino et al., 1997). A paleoseismological trench was also performed across one of these scarps, attesting the activity of these shear planes also in recent times, providing indications result about the deformation style.

    This work aims at presenting the ongoing research activities carried out in Working Group 1 'Novel GPR instrumentation' of the COST (European COoperation in Science and Technology) Action TU1208 'Civil Engineering Applications of Ground Penetrating Radar' (www.GPRadar.eu). The principal goal of the COST Action TU1208 is to exchange and increase scientific-technical knowledge and experience of GPR techniques in civil engineering, simultaneously promoting throughout Europe the effective use of this safe and non-destructive technique in the monitoring of infrastructures and structures. Working Group 1 (WG1) of the Action focuses on the development of innovative GPR equipment dedicated for civil engineering applications. It includes three Projects. Project 1.1 is focused on the 'Design, realisation and optimisation of innovative GPR equipment for the monitoring of critical transport infrastructures and buildings, and for the sensing of underground utilities and voids.' Project 1.2 is concerned with the 'Development and definition of advanced testing, calibration and stability procedures and protocols, for GPR equipment.' Project 1.3 deals with the 'Design, modelling and optimisation of GPR antennas.' During the first year of the Action, WG1 Members coordinated between themselves to address the state of the art and open problems in the scientific fields identified by the above-mentioned Projects [1, 2]. In carrying our this work, the WG1 strongly benefited from the participation of IDS Ingegneria dei Sistemi, one of the biggest GPR manufacturers, as well as from the contribution of external experts as David J. Daniels and Erica Utsi, sharing with the Action Members their wide experience on GPR technology and methodology (First General Meeting, July 2013). The synergy with WG2 and WG4 of the Action was useful for a deep understanding of the problems, merits and limits of available GPR equipment, as well as to discuss how to quantify the reliability of GPR results.

    monitoring stations. This has been carried out on the basis of: i) hydrogeologic and structural studies in order to assess the underground fluid circulation regime; ii) a detailed geochemical study of all the natural manifestations present in the selected territories, such as cold and hot springs and gas emission zones; iii) logistical aspects. Therefore, a detailed hydrogeochemical study was performed in 2002. A total of 150 water points were sampled in Garfagnana/Lunigiana area (N-W Tuscany) and analysed. Based on the results of this multidisciplinary study, five water points suitable for the installation of the monitoring stations, were selected. They are: Bagni di Lucca (Bernabò spring), Gallicano (Capriz spring) and Pieve Fosciana (Prà di Lama spring) in Garfagnana, Equi Terme (main spring feeding the swimming pool of the thermal resort) and Villafranca in Lunigiana (well feeding the public swimming pool). In the Amiata area, in the preliminary campaign, 69 water points were sampled and analyzed and five sites were selected. They are Piancastagnaio, Santa Fiora, Pian dei Renai and Bagnore, which are fed by the volcanic aquifer, and Bagno Vignoni borehole, which is fed by the evaporite carbonate aquifer. The installation and start-up process of the monitoring systems in the Garfagnana-Lunigiana area begun in November 2002; in the Monte Amiata region it begun in June 2003. From the day of installation, a periodic water sampling and manual measurement of the main physical and physicochemical parameters have been carried out on a monthly basis. Such activity has the double function of performing a cross-check of the monitoring instrumentation, and carrying out additional chemical and isotopic analysis. The continuous automatic monitoring stations operate with flowing water (about 5 litres per minute) and record the following parameters: temperature (T), pH, electrical conductivity (EC), redox potential (ORP) and the content of CO2 and CH4 dissolved in water.

    the first archaic settlement (late 6th cent. BC) was unearthed. The Graeco-Roman town expanded downhill, exploiting the growth of a coastal plain, where occasional phases of flooding coexisted with the life of the citizens [6]. The onset of the 3rd cent. AD was characterized by phases of extreme floods which also occurred during the 4th and 5th cent. AD leading to several meters of ground-level aggradation and the burial of buildings [6, 7]. Although the three investigated sites are located in rather different morphological context, they show the evidence of a disequilibrium in the morphodynamics which started in the 3rd-4th cent. AD. The vast amount of collected data strongly suggest that this disequilibrium is a clear sign of a socio-economic decline which affected the Roman Empire during this period rather than the consequence of a climatic deterioration towards dryer conditions, for which no detailed data are available in the Mediterranean area [8]. The abandonment of the towns and their surroundings triggered increased soil erosion on the slopes suffering deforestation and in the farmlands for reduced maintenance, enhancing accumulation rates at the foothills and along coastal areas.

    The construction of an astronomical time scale for the early Paleogene is hampered by ambiguities in the number, correlation and tuning of 405-kyr eccentricity related cycles in deep marine records from ODP cores and land-based sections. The two most competing age models result in astronomical ages for the K/Pg boundary that differ by ~750 kyr (~66.0 Ma of Vandenberghe et al. (2012) versus 65.25 Ma of Westerhold et al. (2012); these ages in turn are consistent with proposed ages for the Fish Canyon sanidine (FCs) that differ by ~300 kyr (28.201 Ma of Kuiper et al. (2008) versus 27.89 Ma of Westerhold et al. (2012)); an even older age of 28.294 Ma is proposed based on a statistical optimization model (Renne et al., 2011). The astronomically calibrated FCs age of 28.201 ± 0.046 Ma of Kuiper et al. (2008), which is consistent with the astronomical age of ~66.0 Ma for the K/Pg boundary, is currently adopted in the standard geological time scale (GTS2012). Here we combine new and published data in an attempt to solve the controversy and arrive at a stable nuemrical time scale for the early Paleogene. Supporting their younger age model, Westerhold et al. (2012) argue that the tuning of Miocene sections in the Mediterranean, which underlie the older FCs age of Kuiper et al. (2008) and, hence, the coupled older early Paleogene age model of Vandenberghe et al. (2012), might be too old by three precession cycles. We thoroughly rechecked this tuning; distinctive cycle patterns related to eccentricity and precession-obliquity interference make a younger tuning that would be consistent with the younger astronomical age of 27.89 Ma for the FCs of Westerhold et al. (2012) challenging. Next we compared youngest U/Pb zircon and astronomical ages for a number of ash beds in the tuned Miocene section of Monte dei Corvi. These ages are indistinguishable, indicating that the two independent dating methods yield the same age when the same event is dated. This is consistent with results

    The CO-ordinated Regional Downscaling Experiment (CORDEX) has to date seen the publication of at least ten journal papers that examine the African domain during 2012 and 2013. Five of these papers consider Africa generally (Nikulin et al. 2012, Kim et al. 2013, Hernandes-Dias et al. 2013, Laprise et al. 2013, Panitz et al. 2013) and five have regional foci: Tramblay et al. (2013) on Northern Africa, Mariotti et al. (2014) and Gbobaniyi el al. (2013) on West Africa, Endris et al. (2013) on East Africa and Kalagnoumou et al. (2013) on southern Africa. There also are a further three papers that the authors know about under review. These papers all use an observed rainfall and/or temperature data to evaluate/validate the regional model output and often proceed to assess projected changes in these variables due to climate change in the context of these observations. The most popular reference rainfall data used are the CRU, GPCP, GPCC, TRMM and UDEL datasets. However, as Kalagnoumou et al. (2013) point out there are many other rainfall datasets available for consideration, for example, CMORPH, FEWS, TAMSAT & RIANNAA, TAMORA and the WATCH & WATCH-DEI data. They, with others (Nikulin et al. 2012, Sylla et al. 2012) show that the observed datasets can have a very wide spread at a particular space-time coordinate. As more ground, space and reanalysis-based rainfall products become available, all which use different methods to produce precipitation data, the selection of reference data is becoming an important factor in model evaluation. A number of factors can contribute to a uncertainty in terms of the reliability and validity of the datasets such as radiance conversion algorithims, the quantity and quality of available station data, interpolation techniques and blending methods used to combine satellite and guage based products. However, to date no comprehensive study has been performed to evaluate the uncertainty in these observational datasets. We assess 18 gridded

    into the world of research by Sir Roger Penrose, who was his PhD supervisor. They worked on Twistor theory, which was one of the foremost runners in the race to quantize gravity at the time. Later in 1971, he joined Quaid-i-Azam University (then Islamabad University) and developed research collaborations with several well-known physicists and mathematicians including John Archibald Wheeler and Remo Ruffini. Of special mention are his efforts with Abdus Salam (NL) for encouraging Physics and Mathematics in the Third World and especially in Pakistan (by running the Salam Prize in Science). Asghar has since become one of the world's top relativists and a leading name in the study of symmetries. In 2004, he founded the Centre for Advanced Mathematics and Physics at NUST. Under his dynamic leadership, the centre has become as influential as any other institute of Pakistan in the development of Mathematics and Mathematical Physics within a very short time. One of his many talents is his amazing ability to detect potential for science among his students. As a result he has been able to successfully guide an astonishing number of PhDs - 14 to be exact and still counting, and no doubt this has been his greatest contribution to Relativity in Pakistan. Asghar has received several national and international awards and honours for his services to science in and outside Pakistan. 65th Birthday Celebrations of the 65th birthday of Asghar Qadir during the third Italian-Pakistani workshop on Relativistic Astrophysics These Proceedings contain revised versions of selected papers presented at the Workshop, which has been sponsored by the Salento University, the National University of Sciences and Technology, the Abdus Salam International Center for Theoretical Physics and the National Institute of Nuclear Physics (INFN, Section of Lecce). All these institutions are acknowledged here for their support together with the bank Monte dei Paschi di Siena. Participants Participants of the third

    neutron spin echo measurements, the effect of temperature on dynamic cluster formation of concentrated lysozyme solutions. Xin Li et al explore the use of the newly developed technique of spin echo small angle neutron scattering (SESANS) to investigate the structure of a colloid. They find the SESANS is able to resolve structural heterogeneity, at both intra- and inter-colloidal length scales. The choice of the topics and their elaboration reflects both the diversified current and past research interests of Professor Chen to whom this special section of Journal of Physics: Condensed Matter is dedicated. The issue contains papers from a substantial number of the invited speakers. The papers are arranged in the three categories of water, other glass-forming liquids, and colloids. It is our pleasure to thank all speakers, section chairs and participants who contributed to the great success of the workshop, and to all authors for their additional efforts in preparing their manuscripts. The scientific program of the workshop was organized by Professor Sow-Hsin Chen and Professor Piero Baglioni. The meeting was only possible with the generous financial support of the Consorzio per lo Sviluppo dei Sistemi a Grande Interfase (CSGI) and the University of Florence, Italy. Finally, we express our warmest gratitude to all the members of the local organizing committee and to the staff of the CSGI for all their assistance and great efforts in organizing this meeting.

    microcontroller platform, Arduino. The very limited cost of the system could represent a step towards a cheaper and more widespread application of accurate and automated infiltration rate measurement. However, automatic data collection increases measurement speed, permits measurement at short time intervals, improves measurement precision, allows for more efficient data handling and analysis, and reduces the amount of effort involved and the potential for errors that may occur when manual procedures are applied (Di Prima et al., 2016). The main objective of this study was to determine soil hydraulic properties by using the combination of the automated infiltrometer and the BEST algorithm in a natural Mediterranean oak forest. The forest is located in a typical Mediterranean area, within the public forest La Hunde, Valencia (NE Spain). Two contiguous plots established in previous studies conducted by González-Sanchis et al. (2015) were selected, one of them was thinned reducing the forest density from 861 to 414 tree per ha. Control plot was not thinned. These authors studied the water cycle during the period 2012-2013. In particular, they characterized and compared the plots in term of throughfall, stemflow, soil moisture and transpiration, concluding that the AFM results in an increasing water availability, and at the same time in a substantial maintenance of overland and surface flow, precluding therefore enhancement of erosion rate. In this paper, the focus was put on the impacts of thinning on soil hydraulic properties, such as infiltration capacity, hydraulic conductivity and soil water retention, determined by simplified and low-cost methods in connection with a hydrology-oriented silviculture.

This might be related to a differential sedimentary load between proximal and distal portions of the basin related to increased erosion, especially in the Alps in hinterland areas and corresponding sedimentation in the foreland, both triggered by climate change in the Mid-Pleistocene (e.g. Muttoni et al., 2002).
