  2. HT_BIM: La modellazione parametrica per l’analisi del rischio nei centri storici

    Directory of Open Access Journals (Sweden)

    Assunta Pelliccio

    2017-06-01

    Full Text Available I centri storici minori sono dei monumenti d’ambiente da salvaguardare perché vulnerabili sia dal punto di vista sismico che ambientale. La gestione di queste realtà urbane è particolarmente complessa a causa dell’eterogeneità dei dati relativi alle singole unità edilizie, aggregati strutturali e intero ambito urbano. Negli ultimi anni i sistemi parametrici BIM hanno dato un enorme contributo alla progettazione, pianificazione, costruzione etc. di nuovi edifici e anche alla gestione del patrimonio culturale. L’obiettivo di questo lavoro è lo sviluppo del sistema Historical Town Building Information Modeling (HT_BIM, ovvero di un sistema BIM specifico per gli aggregati di edifici storici che, sulla base del rilievo, consente di individuare vulnerabilità legate sia ad aspetti strutturali sia a fenomeni di degrado da vento e soleggiamento.

    Full Text Available Systematics, phylogeny and geographical distribution of the South American species of Centris (Paracentris Cameron, 1903, and Centris (Penthemisia Moure, 1950, including a phylogenetic analysis of the "Centris group" sensu Ayala, 1998 (Hymenoptera, Apoidea, Centridini. A cladistic analysis with the objective of testing the hypothesis of monophily of Centris (Paracentris Cameron, 1903, and of studying its phylogenetic relationships with the other subgenera that belong to the Centris group, sensu Ayala, 1998, and the relationships among the species that occur in South America, is presented. Centris (Paracentris is a group of New World bees of amphitropical distribution, especially diversified in the Andes and in the xeric areas of South and North America. Thirty-one species were included in the analysis, four considered as outgroup, and 49 characters, all from external morphology and genitalia of adult specimens. Parsimony analyses with equal weights for the characters and successive weighting were performed with the programs NONA and PAUP, and analyses of implied weighting with the program PeeWee. The strict consensus among the trees obtained in all the analyses indicates that C. (Paracentris, as previously recognized, is a paraphyletic group. In order to eliminate that condition, the subgenera C. (Acritocentris, C. (Exallocentris and C. (Xerocentris, all described by SNELLING (1974 are synonymized under C. (Paracentris. The subgenus C. (Penthemisia Moure, 1950, previously considered a synonym of C. (Paracentris, is reinstated, but in a more restricted sense than originally proposed and with the following species: Centris brethesi Schrottky, 1902; C. buchholzi Herbst, 1918; C. chilensis (Spinola, 1851, C. mixta mixta Friese, 1904, and C. mixta tamarugalis Toro & Chiappa, 1989. Centris mixta, previously recognized as the only South American species of the subgenus C. (Xerocentris, a group supposedly amphitropical, came out as the sister-species of

    1997-03-01

    Nowadays one of the most important deterioration regarding the environment comes from the high production of solid waste and the way of approaching their management. In Italy (in this report the authors examine in particular the case of Rome) there is still a situation of low efficacy (very few instruments) and low efficiency (costs/benefits ratio) in household waste management. As it results from the analysis of more advanced European examples,, the waste management policy must be based on two key factors: quantity control and reduction, on the one side, and specific instruments for different type/quality of waste on the other side. In order to manage the waste quantity and quality it is necessary to modify consumer and producer behaviour. Only new behaviour models and technical innovation in all production sectors can reduce the problem upstream, because all downstream processes, however sophisticated, are expensive and have a negative environmental impact. There are three instruments to produce an efficient and integrated policy of waste management: a system of pricing (Tax and subsidy), prohibitions in some cases, but especially information and education.

    Based on the currently available literature, this paper is aimed at providing a sort of the <> on the use of peracetic acid (C{sub 3}COOOH{identical_to} Paa) as disinfectant of biologically treated municipal wastewater: the growing interest for this substance, used since many years in other sectors (e.g., food-industry, breweries, etc.) is mainly due to the claimed limited formation, if any, of harmful disinfecting by-products (Dbp) with consequent lack of toxicity in Paa treated wastewaters. Such features are just the opposite of those of chlorine, i.e. the most used disinfectant for municipal wastewater. During chlorine-disinfecting, in fact, numerous harmful organo-chlorinated Dbp are formed and, accordingly, the toxicity of chlorinated effluents results very high. In spite of the above reported <> properties of Paa, its use at large scale facilities is still restricted and this not only because of its costs but even for the limited knowledge concerning: the actual disinfecting effectiveness towards different pathogens, the nature and the toxicological properties of its potential Dbp, and the disinfecting performances at large scale facilities. The present paper, besides reporting an extensive and useful collection of references concerning Paa, provides a critical review on the current knowledge regarding specific Paa features such as: its disinfecting effectiveness towards different pathogenic micro-organisms, the nature and the toxicity of its disinfecting by-products, the environmental impact of Paa treated effluents, and the operative conditions used at large scale wastewater treatment plants.

    2003-12-01

    Full Text Available Nesting activity of Centris aenea Lepeletier, 1841 was studied in two Brazilian habitats, Caatinga (Monte Santo, Bahia and Cerrado (Palmeiras, Bahia and Luiz Antônio, São Paulo. Nests were excavated in the ground and did not tend to be aggregated together at the two sites, but at Palmeiras, nests were in a large aggregation. Nest architecture consists of a single unbranched tunnel, sloping to vertical, which leads to a linear series of four cells, placed from 8 to 26 cm in depth. Cells are urn-shaped with a rounded base, and their cell caps have a central hollow process, as in other Centridini. Nest architecture of C. aenea was compared to other species of Centris Fabricius, 1804. Provisions are composed of a pollen mass covered by a thin liquid layer on which the egg is placed. Females were observed gathering oil on Mcvaughia bahiana W.R. Anderson flowers from October to March in the Caatinga, and on Byrsonima intermedia A.Juss. as well as other Malpighiaceae species from August to December in the Cerrado. Pollen is gathered by buzzing flowers of Solanaceae, Caesalpiniaceae, Malpighiaceae, and Ochnaceae. Several nectar sources were recorded. There is indirect evidence that Mesoplia sp. parasitizes nests of C. aenea in the Cerrado.

    Full Text Available La ricerca del gruppo di studio della Facoltà di Architettura della “Sapienza” di Roma che coordino indaga, all’interno del tema più generale della “Città in estensione” , il problema di come i centri storici minori possano subire trasformazioni contemporanee “congruenti” con il processo formativo, nella convinzione che occorra accettare il dato incontrovertibile che un organismo urbano, come ogni organismo vivente, non possa che essere sede di continue modificazioni. La ricerca proposta dall'unità locale della Facoltà di Architettura di Valle Giulia, si inquadra nell'ambito più generale della ricerca nazionale condividendone i presupposti che partono dalla considerazione di come le connotazioni paesaggistiche del territorio italiano suggeriscano strumenti alternativi, rispetto agli attuali, del progetto di architettura e la possibilità di una sua originale collocazione, con caratteri specifici, negli scenari internazionali della disciplina. In particolare, fine della ricerca dell'unità locale è il carattere del paesaggio laziale dovuto alla diffusione nel territorio di centri abitati di rilevante interesse storico che vanno rapidamente perdendo la loro qualità insediativa e paesaggistica. Questi centri sono strutturalmente indeboliti, inoltre, dalla presenza dell'area metropolitana romana, con i relativi fenomeni di rapida trasformazione rilevabili nel territorio, il quale va assumendo una forma progressivamente disorganica. La ricerca propone, verificandone le potenzialità in alcuni casi di studio concreti, la lettura dei tessuti dei centri minori, il loro formarsi con caratteri tipici, le potenziali trasformazioni e “annodamenti” in luoghi nodali della città a formare anche nuovi organismi edilizi specializzati che innovano l’edilizia esistente in modo conforme e proporzionato permettendo di evitare uno sprawl specialistico (si veda il caso dello spostamento dei municipi al di fuori del centro che si aggiunge

    Full Text Available A study of four tree-hole nesting bee species of Centris Fabricius, 1804 was conducted between July, 1988 and June, 1990 in isolated and continuous "terra firme" forests at Manaus region. Nests were obtained from wood trap-nests of different diameters and consisted of a linear series of brood cells. Centris dichrootricha (Moure, 1945 and C. terminata Smith, 1874 were the most abundant species. Centris terminata nested principally in gaps and continuous forest and C. dichrootricha in cleared areas and small fragments of forest. More nests were obtained in trap-nests placed at 8 and 15 m height above ground. Nesting activity was more pronounced in the wet season between August and January. Natural enemies are the beetle Tetraonyx Latreille, 1805 and the bees Coelioxys Latreille, 1809, Mesocheira Lepeletier & Serville, 1825 and Mesoplia Lepeletier, 1841. Nest architecture of Centris spp. are described.

    2017-01-01

    Full Text Available Riassunto: Il lungo percorso della Civiltà Nuragica, compreso fra XVII e X-IX secolo a.C., si caratterizza come un’epoca di grandi trasformazioni che si susseguono nel tempo e lasciano visibili tracce in un paesaggio mutevole, come in un succedersi di macroscopiche unità stratigrafiche. Si trasformano profondamente così non solo i monumenti ed il paesaggio, ma anche le stesse strutture sociali e politiche delle comunità nuragiche fino alla trasfigurazione del ricordo in mito nei centri cerimoniali o santuari. Abstract: The long trajectory of the Nuragic civilisation (17th - 10th/9th centuries B.C. is characterised by a succession of dramatic changes leaving visible traces in a varying landscape, like stratigraphy on a regional scale. These changes affect not only the Nuragic monuments and landscape but also the social and political institutions of Nuragic communities, culminating in a transfiguration of memory and a new mythology apparent in ceremonial centres and sanctuaries.

  18. Searching for a manageable pollinator for Acerola orchards: the solitary oil-collecting bee Centris analis (Hymenoptera: Apidae: Centridini).

    Science.gov (United States)

    Oliveira, Reisla; Schlindwein, Clemens

    2009-02-01

    Acerola (Malpighia emarginata DC; Malpighiaceae) is an important fruit crop in Brazil. Among its pollinators, Centris (Heterocentris) analis (F.) stands out due to its abundance at flowers and prompt acceptance of trap-nests. For the first time, we propose the commercial use of Centris bees as orchard pollinators. To develop protocols for rearing and management of these bees, we analyzed trap-nest acceptance, brood-cell construction, and larval diet in Acerola orchards. Although Centris species, in general, use numerous pollen host plants, females of C. analis showed remarkable flower fidelity to Acerola for pollen supply when nesting in the orchard. Such fidelity was previously expected only for floral oil collection. The ease of acceptance of trap-nests by females of C. analis, their prolonged yearly activity period, multivoltine life history, and high pollinator efficiency characterize C. analis as an excellent potentially manageable pollinator in Acerola orchards.

    2006-06-01

    Full Text Available O comportamento de nidificação de Centris (Hemisiella trigonoides Lepeletier, 1841, e o comportamento de seus cleptoparasitas foram estudados em Monte Santo, Bahia, Brasil. As abelhas construíram seus ninhos com uma mistura de solo e óleo, dentro de cavidades preexistentes na madeira de uma construção abandonada, assim como em gomos de bambu de 8 e 9 mm de diâmetro. Os ninhos completados tinham de uma a cinco células alongadas, arranjadas em uma série linear e orientadas horizontalmente. O tempo gasto para construir uma célula foi altamente variável, sendo em geral de 4,5 a 5,5 h. Após finalizar a construção da célula, as fêmeas fizeram uma ou duas viagens para coletar um líquido incolor, provavelmente óleo floral, usado para revestir as paredes internas da célula. Para aprovisionar uma célula foram realizadas de cinco a oito viagens de coleta para obtenção de pólen e néctar, e de quatro a seis viagens para coleta de óleo. Imediatamente após a oviposição, as fêmeas fecharam as células usando o solo que elas tinham coletado previamente. Três espécies cleptoparasitas pertencentes ao gênero Coelioxys Latreille, 1809 atacaram os ninhos. Entradas de cleptoparasitas dentro dos ninhos occorreram, na maioria dos casos, enquanto a fêmea hospedeira estava ausente do ninho. As fêmeas de C.

    Neuropeptideglutamic acid-isoleucine (NEI) as well as melanin concentrating hormone (MCH) is cleaved from the 165 amino acid protein, prepro-melanin concentrating hormone (prepro-MCH). Among many physiological roles of MCH, we demonstrated that intracerebroventricular (icv) injection of MCH induced increases in REM sleep episodes as well as in non REM sleep episodes. However, there are no studies on the effect of NEI on the sleep-wake cycle. As for the sites of action of MCH for induction of REM sleep, the ventrolateral periaqueductal gray (vlPAG) has been reported to be one of its site of action. Although MCH neurons contain NEI, GABA, MCH, and other neuropeptides, we do not know which transmitter(s) might induce REM sleep by acting on the vlPAG. Thus, we first examined the effect of icv injection of NEI on the sleep-wake cycle, and investigated how microinjection of either NEI, MCH, or GABA into the vlPAG affected REM sleep in rats. Icv injection of NEI (0.61μg/5μl: n=7) significantly increased the time spent in REM episodes compared to control (saline: 5μl; n=6). Microinjection of either NEI (61ng/0.2μl: n=7), MCH (100ng/0.2μl: n=6) or GABA (250mM/0.2μl: n=7) into the vlPAG significantly increased the time spent in REM episodes and the AUC. Precise hourly analysis of REM sleep also revealed that after those microinjections, NEI and MCH increased REM episodes at the latter phase, compared to GABA which increased REM episodes at the earlier phase. This result suggests that NEI and MCH may induce sustained REM sleep, while GABA may initiate REM sleep. In conclusion, our findings demonstrate that NEI, a cleaved peptide from the same precursor, prepro-MCH, as MCH, induce REM sleep at least in part through acting on the vlPAG.

  18. The contribution of Nth and Nei DNA glycosylases to mutagenesis in Mycobacterium smegmatis.

    Science.gov (United States)

    The increased prevalence of drug resistant strains of Mycobacterium tuberculosis (Mtb) indicates that significant mutagenesis occurs during tuberculosis disease in humans. DNA damage by host-derived reactive oxygen/nitrogen species is hypothesized to be critical for the mutagenic process in Mtb thus, highlighting an important role for DNA repair enzymes in maintenance of genome fidelity. Formamidopyrimidine (Fpg/MutM/Fapy) and EndonucleaseVIII (Nei) constitute the Fpg/Nei family of DNA glycosylases and together with EndonucleaseIII (Nth) are central to the base excision repair pathway in bacteria. In this study we assess the contribution of Nei and Nth DNA repair enzymes in Mycobacterium smegmatis (Msm), which retains a single nth homologue and duplications of the Fpg (fpg1 and fpg2) and Nei (nei1 and nei2) homologues. Using an Escherichia coli nth deletion mutant, we confirm the functionality of the mycobacterial nth gene in the base excision repair pathway. Msm mutants lacking nei1, nei2 and nth individually or in combination did not display aberrant growth in broth culture. Deletion of nth individually results in increased UV-induced mutagenesis and combinatorial deletion with the nei homologues results in reduced survival under oxidative stress conditions and an increase in spontaneous mutagenesis to rifampicin. Deletion of nth together with the fpg homolgues did not result in any growth/survival defects or changes in mutation rate. Furthermore, no differential emergence of the common rifampicin resistance conferring genotypes were noted. Collectively, these data confirm a role for Nth in base excision repair in mycobacteria and further highlight a novel interplay between the Nth and Nei homologues in spontaneous mutagenesis.

    Dórea, Marcos da C; Dos Santos, Francisco de A R; Lima, Luciene C de L E; Figueroa, Luís E R

    2009-01-01

    A new treatment protocol was developed to analyze pollen residues found in nests of Centris tarsata Smith harvested from nest-traps. The study area was located in the Canudos Biological Station in the municipality of Canudos (09 masculine56'34'S; 38 masculine59'17'W), in the northeastern micro-region of Bahia State, Brazil. The local vegetation is an open caatinga (deciduous dryland vegetation), the regional climate is semi-arid, the average annual temperature is 24.1 masculineC, and the annual regional rainfall rate is 454 mm. Ten nests of C. tarsata were collected in trap-nests during the first semester of 2004. Pollen analysis from the nests required the development of a new methodology that combined techniques of palynological sediment analysis with the more common pollinic analysis by acetolysis. Microscopic analyses employed optical microscopy techniques. The pollinic spectrum of the samples from C. tarsata indicated the presence of 17 pollen types from seven plant families, which were present in assemblage of five to eleven pollen types, pointed to the plants used by bees to feed on their offspring. The most represented plant families were Leguminosae (49.3%) and Solanaceae (43.2%). The most frequent pollen types in the samples were from Solanum paniculatum (43.8%) and Senna rizzini (32.1%). The protocol developed provides a new tool for diet assessment of Centris and other groups of solitary bees.

    The new environmental regulations in Europe require higher standards for design and management of new landfills. Municipal solid wastes (MSW) have to be pretreated before land filling, in order to enable strong reduction of landfill emissions and environmental impact. The paper briefly describes the role of new landfills in solid waste management and the influence of some measures on the reduction of emissions and environmental impact. [Italian] In base alle nuove Direttive italiane e comunitarie, la discarica controllata e' destinata ad avere anche in futuro un ruolo di primo piano nella gestione dei rifiuti solidi urbani. In particolare, saranno destinati a smaltimento in discarica rifiuti pretrattati che garantiscano limitata putrescibilita' e minore impatto ambientale della discarica. Nell'articolo vengono esposte alcune considerazioni sul ruolo delle discariche nelle moderne strategie di smaltimento dei rifiuti solidi urbani, sugli effetti del pretrattamento dei rifiuti sulle emissioni di biogas e percolato dalle discariche e sulle caratteristiche idrauliche e meccaniche delle discariche per rifiuti pretrattati.

    Full Text Available Le finalità del presente saggio si possono sintetizzare in due differenti punti, ma strettamente legati tra di loro. Il primo è quello di illustrare, seppur brevemente, l’insieme delle teorie che hanno portato all’origine e alla affermazione della geografia dello sport, mentre il secondo cercherà di tracciare seppur a grandi linee, le emergenti linee di ricerca nell’ottica del complesso rapporto tra spazio e società. In tal modo si offriranno alcuni spunti di riflessione e nuove chiavi di lettura sul poliedrica relazione tra attività sportiva, intesa come fenomeno socio-culturale, e spazio/territorio, ormai sempre più centrale nelle più recenti politiche di pianificazione territoriale, considerando anche dell’attuale fase di deindustrializzazione che investe i nostri centri urbani.

    Full Text Available La ricerca proposta parte dal presupposto che il metodo di progettazione basato sullo studio della morfologia urbana possa costituire una guida per interventi urbani all’interno dei cosiddetti tessuti “informali”. Gli studi condotti dimostrano infatti che il tessuto urbano informale, il cui sviluppo prescinde da pianificazioni o da logiche normative, risulta però strettamente legato a dinamiche sociali ed economiche. Sotto questo punto di vista lo sviluppo della città informale contemporanea può essere messa a confronto con le dinamiche di formazione e trasformazione dei centri urbani pre-moderni, sottolineando la netta analogia che lega le trasformazioni urbane alle necessità e alle dinamiche sociali, proprie dell’intorno culturale in cui tali organismi urbani si identificano.Il riconoscimento di una logica di sviluppo di tali tessuti, diventa lo strumento in grado di guidarne la rigenerazione urbana, rispettandone la cultura abitativa. / This research start from the hypothesis that the design method, based on the study of urban morphology, can be a guide for urban interventions within the so-called 'informal' fabric. The studies demonstrate that the 'informal' city, the development of which is independent from urban design or legal rules, is closely related to social and economic dynamics. From this point of view the development of the contemporary informal city can be compared with the dynamics of formation and transformation of pre-modern urban fabric, emphasizing the analogy that links the urban transformation to the social needs, own of the surroundings cultural context in which these urban organisms are identified. The recognition of a logical development of these fabrics, becomes the tool that can guide the urban regeneration, respecting the living culture.

    The Nuclear Energy Institute (NEI) provided a brief discussion on the benefits of establishing a new regulatory framework. He suggested that a new paradigm in regulatory thinking is needed and stated that the reactor oversight process (ROP) serves as the appropriate basis for starting these discussions. He suggested that the ROP cornerstones of safety be used as the starting point for developing a new set of General Design Criteria (10 CFR Part 50, Appendix A). It is suggested that new operating criteria, generic risk- informed and performance-based regulations be developed with associated design-specific and regulation-specific regulatory guides

    Full Text Available Sui dati raccolti in otto parchi urbani, comprendenti alcuni parametri acustici e le valutazioni dei fruitori sulla qualità complessiva del parco percepita e di alcune sue caratteristiche, si è proceduto a diverse analisi statistiche. L’analisi delle componenti principali e quella cluster gerarchica sui dati acustici ha fornito una classificazione in tre gruppi risultata poco sovrapponibile a quella ottenuta con l’analisi cluster e delle corrispondenze multiple condotta sui responsi soggettivi. La discrepanza, confermata anche da alcuni modelli di regressione logistica multinomiale, evidenzia l’influenza di altri fattori non acustici sulla percezione dell’ambiente dei parchi urbani. ------ Different statistical analyses have been carried out on data collected in eight urban parks, including some acoustical parameters and the appraisals of park visitors on the perceived overall quality of the park and some of its features. Principal component analysis and hierarchical cluster one on the acoustic data have identified three groups. This classification poorly overlaps that obtained by hierarchical cluster analysis and multiple correspondence one performed on subjective appraisals data. The difference, confirmed also by models developed by multinomial logistic regression, points out the influence of other non-acoustic factors on the perception of the urban parks environment.

    Tenuto conto della omogeneità dei dati nel quadriennio 1999- 2002 e della stagionalità che le meningiti possono avere, sono stati calcolati i tassi di incidenza per i primi cinque mesi dell’anno per tutte le meningiti in generale e per agente eziologico, durante il quadriennio 1999-2002. Tali tassi sono stati confrontati con i tassi corrispondenti nei primi mesi del 2003.

    Risultati: nel primi 5 mesi del 2003 si sono registrati in tutto 48 casi, di cui 9 da meningocco, 13 da pneumococco, 14 virali, 3 da altri agenti batterici e 8 senza agente microbico identificato. Nei 4 anni precedenti erano stati notificati 66 casi di meningite nei primi 5 mesi dell’anno, con una media annua di 16.5. Il tasso di incidenza di meningite in gennaio-maggio è stato quindi il triplo nel 2003 (rischio relativo = 2.9 rispetto ai 4 anni precedenti (p=0.0001. L’eccesso di incidenza si è riscontrato per tutti i tipi di meningite considerati in base all’agente eziologico.

    L’analisi per diverse età ha mostrato un aumento di incidenza sia nei bambini che nei giovani adulti e negli anziani. Non si è riscontrata alcuna differenza statisticamente significativa tra l’incidenza nel comune di Brescia (area urbana rispetto all’intera ASL nel periodo in studio.

    Conclusioni: l’aumento di incidenza per meningiti
    osservato nel 2003 non sembra spiegabile in termini di variabilità casuale del fenomeno da un anno all’altro e riguarda tutti i tipi di meningite e tutte le categorie d

    2007-01-01

    Since USNRC (United State Nuclear Regulatory Committee) initially addressed post-accident sump performance under Unresolved Safety Issue USI A-43, sump blockage issue has gone through GSI-191, Regulation Guide 1.82, Rev. 3 (RG. 1.82 Rev.3), and generic Letter 2004-02 for PWRs (Pressurized Water Reactors). As a response of these USNRC's activities, NEI 04-07 was issued in order to evaluate the post-accident performance of a plant's recirculation sump. The baseline methodology of NEI 04-07 is composed of break selection, debris generation, latent debris, debris transport, and head loss. In analytical refinement of NEI 04-07, computational fluid dynamic (CFD) is suggested for the evaluation of debris transport in emergency core cooling (ECC) recirculation mode as guided by RG. 1.82 Rev.3. In Korea nuclear industry also keeps step with international activities of this safety issue, with Kori 1 plant as a pioneering edge. Korean nuclear industry has been also pursuing development of an advanced PWR of APR1400, which incorporates several improved safety features. One of the key features, considering sump blockage issue, is the adoption of IRWST (In-containment Refueling Water Storage Tank). This device, as the acronym implies, changes the emergency core cooling water injection pattern. This fact makes us to review the applicability of NEI 04-07's methodology. In this paper we discuss the applicability of NEI 04- 07's methodology, and more over, new methodology is proposed. And finally the preliminary debris transport is analyzed

    Full Text Available Abstract Background The use of self-report questionnaires to substitute for visual acuity measurement has been limited. We examined the association between visual impairment and self reported visual function in a population sample of older people in the UK. Methods Cross sectional study of people aged more than 75 years who initially participated in a trial of health screening. The association between 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ scores and visual impairment (defined as an acuity of less than 6/18 in the better eye was examined using logistic regression. Results Visual acuity and NEI-VFQ scores were obtained from 1807 participants (aged 77 to 101 years, 36% male, from 20 general practices throughout the UK. After adjustment for age, gender, practice and NEI-VFQ sub-scale scores, those complaining of poor vision in general were 4.77 times (95% CI 3.03 to 7.53 more likely to be visually impaired compared to those who did not report difficulty. Self-reported limitations with social functioning and dependency on others due to poor vision were also associated with visual impairment (odds ratios, 2.52, 95% CI 1.55 to 4.11; 1.73, 95% CI 1.05 to 2.86 respectively. Those reporting difficulties with near vision and colour vision were more likely to be visually impaired (odds ratios, 2.32, 95% CI 1.30 to 4.15; 2.25, 95% CI 1.35 to 3.73 respectively. Other NEI-VFQ sub-scale scores were unrelated to measures of acuity. Similar but weaker odds ratios were found with reduced visual acuity (defined as less than 6/12 in the better eye. Although differences in NEI-VFQ scores were small, scores were strongly associated with visual acuity, binocular status, and difference in acuity between eyes. Conclusion NEI-VFQ questions regarding the quality of general vision, social functioning, visual dependency, near vision and colour vision are strongly and independently associated with an objective measure of visual impairment in an

    We previously showed that short-term hypo- and hyperthyroidism induce changes in neuropeptide glutamic-acid-isoleucine-amide (NEI) concentrations in discrete brain areas in male rats. To investigate the possible effects of hypo- and hyperthyroidism on NEI concentrations mainly in hypothalamic areas related to reproduction and behavior, female rats were sacrificed at different days of the estrous cycle. Circulating luteinizing hormone (LH), estradiol and progesterone concentrations were measured in control, hypothyroid (hypoT, treated with PTU during 7-9 days) and hyperthyroid (hyperT, l-T4 during 4-7 days) animals. Both treatments blunted the LH surge. Hypo- and hyperthyroidism increased estradiol concentrations during proestrus afternoon (P-PM), although hypoT rats showed lower values compared to control during proestrus morning (P-AM). Progesterone levels were higher in all groups at P-PM and in the hyperT during diestrus morning (D2). NEI concentrations were lower in hypoT rats during the estrous cycle except in estrus (E) in the peduncular part of the lateral hypothalamus (PLH). They were also reduced by both treatments in the perifornical part of the lateral hypothalamus (PeFLH) during P-PM. Hypothyroidism led to higher NEI concentrations during P-PM in the organum vasculosum of the lamina terminalis and anteroventral periventricular nucleus (OVLT+AVPV). The present results indicate that NEI concentration is regulated in a complex manner by hypo- and hyperthyroidism in the different areas studied, suggesting a correlation between NEI values and the variations of gonadal steroid levels during estrous cycle. These changes could be, in part, responsible for the alterations observed in the hypothalamic-pituitary-gonadal axis in these pathologies. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Centris (Ptilotopus are large bees and important pollinators in the Neotropical region. Its biology and behavior is still poorly known and only a few observations have been published. In this paper, observations on the biology of C. (Ptilotopus scopipes Friese, 1899, a species that occurs in the "cerrados" of Brazil, are presented. The study was conducted in the Estação Ecológica de Jataí, in Luiz Antônio, São Paulo, during the active period of the adults (November through April. Females collected pollen from flowers of Solanaceae and Caesalpiniaceae, by vibration, and floral oils from Malpighiaceae belonging to the genera Byrsonima, Banisteriopsis, Stigmaphyllon and Peixotoa. Floral resources are carried in the hind leg scopae to the nests, which are excavated in the walls of epigeous nests of the termite Procornitermes araujoi Emerson, 1952 (Termitidae, Nasutitermitinae. The main tunnel entered the termite nest at an ascending angle ending in a vestibulum. Two parallel, vertical burrows forming linear series of cells descended from the vestibulum. The upper cell (the nearest to the nest entrance was filled with soil. This might represent a protection against parasites. During the study, one female of Acanthopus excellens Schrottky, 1902 (Apidae, Ericrocidini, a cleptoparasitic bee, was captured when leaving one of the nests. A male of C. scopipes emerged eleven months after cell closure, suggesting a univoltine cycle for this species.

    Obiettivi: l’ospedale dovrebbe rappresentare un modello per la promozione della salute, tuttavia, nonostante i divieti di legge, l’abitudine di fumare in ospedale è ancora diffusa. Obiettivo dello studio è rilevare l’abitudine al fumo di personale sanitario, pazienti e visitatori, nei locali dell’AOUS.

    Metodi: alcuni studenti universitari, durante le loro attività curricolari, hanno percorso i locali del policlinico in orari diversi, contando il numero di persone incontrate, operatori sanitari e pazienti/visitatori, e indicando il numero di coloro che stavano fumando, in entrambe le categorie. Questo studio è stato ripetuto negli anni 1998, 1999 e 2003.

    Risultati: la prevalenza di persone che stavano fumando è risultata del 6,4% nel 1998, del 3,8% nel 1999 e dell’1,1% nel 2003. La prevalenza di operatori sanitari che fumavano rispetto al totale dei fumatori è risultata rispettivamente del 25%, del 26% e del 23,8%. Nei due anni passati, nell’atrio, nel bar e nelle zone antistanti i reparti c’era una maggiore presenza di persone che fumavano; mentre nell’ultima indagine sono stati riscontrati più fumatori, oltre che nell’atrio, nei corridoi del piano didattico, zona non indagata in precedenza. Nell’ultima rilevazione, non sono stati individuati fumatori nei due bar del policlinico; mentre sono sempre stati rilevati, in numero esiguo, operatori sanitari che fumano all’interno delle corsie di degenza.

    Conclusioni: la diminuzione costante del numero di fumatori in ospedale, mostra come ci sia stato negli ultimi anni un rispetto sempre maggiore del divieto di fumo nei luoghi di cura. Il coinvolgimento di futuri medici permette di promuovere il problema fumo in ospedale.

    1993-06-01

    Huang Di Nei Jing, the first systematic Chinese medical book, was compiled from the observations of imperial herbal doctors in the Qin and Han periods (221 BC - 220 AD). From this classic traditional source may be derived the concept of a balanced and complete diet and probably the world's first dietary guidelines. Basic to the tradition are han, re, wen and bu foods, respectively 'cold', 'hot', 'neutral', 'strengthening'. Basic to Chinese cuisine are jan and tsai- 'cereal' (the rice staple and main meal) and 'dishes' to accompany the rice. Chinese traditional medicine, as in Huang Di Nei Jing, considers the nourishment of body and mind. It also emphasises that herbal medicine and food have the same origin. Diet was essential to the prevention of disease which a glossary of Chinese terms is given at the end of the paper in the Chinese tradition, was superior to treatment.

    The Nuclear Energy Institute (NEI) provided a brief presentation on the state of energy demand in the United States and discussed the improving economics for new nuclear power plants. He discussed the consolidation of companies under deregulation and the ability of these larger companies to undertake large capital projects such as nuclear power plant construction. He discussed efforts under way to support a new generation of plants but noted that there needs to be greater certainty in the licensing process. He discussed infrastructure challenges in terms of people, hardware, and services to support new and current plants. He stated that there needs to be fair and equitable licensing fees and decommissioning funding assurance for innovative modular designs such as the PBMR. He concluded that NRC challenges will include resolving 10 CFR Part 52 implementation issues, establishing an efficient and predictable process for siting, COL permits and inspection, and an increasing regulatory workload

    The more common lodger bee occurring in the dry forest of Costa Rica, Centris bicornuta Muscáry), has been observed nesting in new nest cavities drilled into wooden blocks placed next to cavities used by another female within 2-3 days. In contrast, new nest cavities placed in similar areas with no nesting Centris nearby were not used for weeks. These observations suggest that the presence of nesting bees may play a role in nest site selection. To confirm our observations, new nest cavities were placed in areas with or without nesting. We found nest initiation in newly placed nest cavities only in areas where bees were actively nesting. To examine the possibility that nesting locations are not unique, we placed new nest cavities in new locations either with (a) a number of completed nest cavities or (b) placed alone. Within three days we only found bees nesting in the newly placed nest cavities in situation "a". The results suggested that odor might be involved. We next compared nesting in new cavities placed alone with cavities contaminated with either (a) nest entrance plug material, (b) nest nectar, (c) nest pollen or (d) a combination of pollen and nectar. Nesting was significantly low in cavities placed next to cavities with nest entrance plug material (a), and high in cavities placed next to cavities "b, c, or d". The results suggest that pollen and /or nectar odor play a role in the location of potential nest sites.

    Full Text Available Introduction: Tuberculosis (TB is a human disease caused by Mycobacterium tuberculosis (Mtb. Treatment of TB requires long-term courses of multi-drug therapies to eliminate subpopulations of bacteria, which sometimes persist against antibiotics. Therefore, understanding of the mechanism of Mtb antibiotic-resistance is extremely important. During infection, Mtb overcomes a variety of body defense mechanisms, including treatment with the reactive species of oxygen and nitrogen. The bases in DNA molecule are susceptible to the damages caused by reactive forms of intermediate compounds of oxygen and nitrogen. Most of this damage is repaired by the base excision repair (BER pathway. In this study, we aimed to biochemically characterize three Mtb DNA repair enzymes of BER pathway. Methods: XthA, nfo, and nei genes were identified in mycobacteria by homology search of genomic sequences available in the GenBank database. We used standard methods of genetic engineering  to clone and sequence Mtb genes, which coded Nfo, XthA and Nei2 repair enzymes. The protein products of Mtb genes were expressed and purified in Escherichia coli using affinity tags. The enzymatic activity of purified Nfo, XthA, and Nei2 proteins were measured using radioactively labeled DNA substrates containing various modified residues. Results: The genes end (Rv0670, xthA (Rv0427c, and nei (Rv3297 were PCR amplified using genomic DNA of Mtb H37Rv with primers that contain specific restriction sites. The amplified products were inserted into pET28c(+ expression vector in such a way that the recombinant proteins contain C-terminal histidine tags. The plasmid constructs were verified by sequencing and then transformed into the Escherichia coli BL21 (DE3 strain. Purification of recombinant proteins was performed using Ni2+ ions immobilized affinity column, coupled with the fast performance liquid chromatography machine AKTA.

    2010-08-01

    The aim of this study was to evaluate different approaches to scoring the National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25) in patients with low vision including scoring by the standard method, by Rasch analysis, and by use of an algorithm created by Massof to approximate Rasch person measure. Subscale validity and use of a 7-item short form instrument proposed by Ryan et al. were also investigated. NEI VFQ-25 data from 50 patients with low vision were analyzed using the standard method of summing Likert-type scores and calculating an overall average, Rasch analysis using Winsteps software, and the Massof algorithm in Excel. Correlations between scores were calculated. Rasch person separation reliability and other indicators were calculated to determine the validity of the subscales and of the 7-item instrument. Scores calculated using all three methods were highly correlated, but evidence of floor and ceiling effects was found with the standard scoring method. None of the subscales investigated proved valid. The 7-item instrument showed acceptable person separation reliability and good targeting and item performance. Although standard scores and Rasch scores are highly correlated, Rasch analysis has the advantages of eliminating floor and ceiling effects and producing interval-scaled data. The Massof algorithm for approximation of the Rasch person measure performed well in this group of low-vision patients. The validity of the subscales VFQ-25 should be reconsidered.

    Obiettivi: valutare le frequenze dei principali geni metabolici in un campione di casi di GC (Carcinoma Gastrico e di controlli, per determinare se esiste un’associazione con il rischio di GC, e considerare le possibili associazioni tra i genotipi studiati ed alcuni parametri clinico-patologici.

    Metodi: è stato condotto uno studio caso-controllo ospedaliero, tra novembre 1999 e maggio 2003 reclutando 48 pazienti con diagnosi di adenocarcinoma gastrico sottoposti a gastrectomia, e 48 controlli appaiati per sesso ed età presso il Policlinico Universitario “A. Gemelli” in Roma. Per genotipizzare gli individui rispetto ai geni GSTM1, NAT2, SULT1A1, CYP1A1, CYP2E1 (5’ flanking e introne 6, è stata usata la tecnica della PCR con analisi del profilo dei frammenti di restrizione (PCR-RFLP. L’analisi statistica ha previsto l’impiego di test non parametrici e della regressione logistica.

    Risultati: le frequenze dei polimorfismi nei geni metabolici sono risultate in alcuni casi differenti nei casi rispetto ai controlli sebbene non si evidenzi una differenza statisticamente significativa. In particolare il genotipo GSMT1 null è più elevato nei pazienti rispetto ai controlli (63.8% vs. 51% e gli individui NAT2 acetilatori lenti risultano più frequenti nei casi rispetto ai controlli (69.6% vs. 57.45%. L’istotipo diffuso di GC è associato significativamente ai pazienti eterozigoti per l’allele SULT1A1 (c_= 8.216; p= 0.018, ed i pazienti NAT2 acetilatori lenti tendono ad avere un grading tumorale alto (c_= 7.425; p= 0.006.

    Conclusioni: i risultati preliminari di questo studio evidenziano associazioni tra alcuni genotipi metabolici e parametri clinico-patologici, che se confermati potrebbero permettere di identificare sottogruppi con prognosi più sfavorevole di GC da indirizzare preventivamente verso trattamenti specifici.

Si presenta questa iniziativa come un modello per la salvaguardia del patrimonio culturale del nostro Paese che è vastissimo, distribuito su numerose piccole realtà locali e spesso non adeguatamente tutelato. Il finanziamento erogato dallo Stato e dagli enti locali rappresenta, ancora oggi, la fonte di sostentamento principale per le iniziative che coinvolgono il settore dei beni culturali. Tuttavia, l’attuale congiuntura economica ha favorito la nascita e la diffusione di strumenti e modalità di finanziamento alternativi attraverso i quali poter supportare il restauro del nostro Patrimonio Culturale. Il crowdfunding è il metodo che più si sta diffondendo ed è una forma di microfinanziamento dal basso finalizzato alla creazione e al supporto di un processo collaborativo tra singoli soggetti che utilizzano il proprio denaro per sostenere iniziative di singoli individui o di organizzazioni più strutturate. Molteplici sono gli esempi attuali di impiego del crowdfunding, da parte di associazioni e comitati, per il restauro di monumenti di interesse nazionale.

    Recently, under the de-regulation environment, nuclear industry has attempted various approaches to improve the economics of Nuclear Power Plants (NPP). One of these efforts is the Risk Informed/Performance-Based Operation (RIPBO). This approach uses the risk and performance information to manage the resources effectively and efficiently that are used in the operation of NPP. In RIPBO, PSA quality is one of the most important things. The nuclear industry and regulatory body of U.S.A have developed a measure to evaluate the quality of PSA. NEI (Nuclear Energy Institute) has developed a guidance called 'NEI PRA Peer Review Guidance,' and NRC (Nuclear Regulatory Committee) and ASME have developed the 'PRA Standard.' In Korea, several projects are on going now, such as the extension of AOT/STI of RPS/ESFAS, Risk-Informed In-Service Inspection (RI-ISI). However, in Korea, there have been no attempts to evaluate the quality of PSA model itself. Therefore, we cannot be sure about the quality of PSA whether or not the present PSA model can be used for the risk-informed applications such as mentioned above. We can say that the evaluation of PSA model quality is the basis for the RIPBO. In this report, we have evaluated the quality of PSA model for Ulchin 3 and 4 units based on the NEI guidance. We, also, have derived what items are to be improved to upgrade the quality of PSA model and how it can be improved. This report can be used as the base of RIPBO work in Korea. The review result based on ASME Standard is published as the separated technical report of KAERI

The highest nest frequencies occurred from December to February (summer), with no nests foundations from August to October (winter - early spring). Two-hundred eight adults emerged from 347 brood cells, being 164 males and 116 females (1: 0.42). During the study period sex ratio was male biased ({chi}{sup 2} = 9.342; gl = 10; P < 0.05). C. terminata nested in holes with diameters 6, 8, 10 mm, but 84,2% were constructed in 8 and 10 mm. nests had one to seven cells arranged in a linear series with the cell's partitions built with a mixture of sand and resin or oil. Male is significantly smaller than female, which emerges from the first cells constructed. Immature mortality occurred in 14.1% of brood cells (n 49), of which 13.0% were due fail in development and 1.2% due to parasitism of Coelioxys sp. (Hymenoptera: Megachilidae) e Tetraonyx sp. (Coleoptera: Meloidae). In the study site, weather, mainly pluviosity, rather than natural enemies influenced seasonal population abundance. The long period of nesting activity, local abundance and usage of trap nests, suggest the potential of C. terminata for management aiming at pollination of native and cultivated plants. (author)

    The zone of the Latian Volcano extends in an area of about 1.500 km{sup 2} in the south-est of Rome. This area is thickly peopled, owing to the presence of many towns (Velletri, Frascati, Albano, etc.) in the central share of the volcanic edifice. Actually the volcanic edifice of Alban Hills shows in the central and higher area, a large caldera (Tuscolana-Artemisia). This caldera has a sub-circular form wide 10 km in diameter and 75 km{sup 2} in area. The excessive groundwater drawing by wells caused the depauperation of underground resources so to produce a real crisis since 1984. To restore of water balance of the aquifer of the Latian Volcano, an important contribution could be given by the artificial recharge of the higher aquifer. This recharge could be done by allowing to meteoric water to inflitrate as much as possible in the underground by realization of an artificial lake; otherwise by making a series of little infiltration-basins together with infiltration-wells. Besides the realization of the artificial lake could give back to the landscape a characteristic component present in the past centuries until very recent times. [Italian] L'area del Vulcano Laziale si estende su una superficie di circa 1500 km{sup 2} a sud-est di Roma in un'area densamente popolata per la presenza di numerosi centri urbani (Velletri, Frascati, Albano, ecc.), ubicati nella parte centrale dell'ufficio vulcanico. Attualmente l'edificio vulcanico dei Colli Albani presenta in posizione centrale un'ampia caldera sommitale con forma subcircolare, con diametro medio di circa 10 km ed estensione di circa 75 km{sup 2}. Gli eccessivi prelievi di acqua sotterranea hanno condotto ad un impoverimento della risorsa idrica fino a determinare una vera e propria crisi manifestatasi a partire dal 1984. Per riequilibrare il bilancio idrico dell'acquifero del Vulcano Laziale, un contributo significativo potrebbe provenire dalla ricarica artificiale dell

    Full Text Available The aim of this study was to identify, by sediment pollen analysis, the plant species used as floral resources for the provisioning of brood cells in Centris (Hemisiella tarsata, in an area of Caatinga, within the municipality of Nova Soure, Bahia State, Brazil. The analysis of pollen contents from three brood cells revealed 11 pollen types, corresponding to four botanical families. Malpighiaceae was represented most, followed by Leguminosae, Ochnaceae, and Solanaceae, the latter two represented by just a single pollen type each. On the basis of the percentages in the samples, it was possible to infer that C. tarsata visited distinct plants, but intensified its pollen collection in species related to Aeschynomene martii and Solanum paniculatumpollen types, which are considered the most important pollen sources in the larval diet of this bee. In addition to the pollen sources, we have also recorded seven pollen types regarded as oil ones, all related to the Malpighiaceae family. The information about the resources for C. tarsata can be of great relevance, in view of the importance of these bees in the pollination of native flora.

    The Neotropical bee Centris (Hemisiella) dichrootricha is a solitary bee that nests in pre-existing cavities that occur in the rain forest. This study describes the nesting biology of C. dichrootricha and its preference for nesting in Cerrado and gallery forest habitats. The study was conducted from January 2012 and December 2013, in Mirador State Park in the municipality of Formosa da Serra Negra, Maranhão State, Brazil. For this, wooden trap-nests of 6, 8, 10, 12, 14 and 16 mm in diameter were used; a total of 300 trap-nests were placed in the gallery forest and Cerrado areas, respectively. Traps were monitored monthly and all completed nests were collected and replaced with empty ones. The nests were then taken to the laboratory to analyze bee development and emergence, nests characteristics and parasites presence. The species used 29 of the trap-nests, which had diameters of 8, 10, 12 and 14 mm. A total of 87 C. dichrootricha specimens emerged. The nests were parasitized by two bee species, Mesocheira bicolor (Apinae) and Coelioxys sp. (Megachilinae), and one fly species, Antrax sp. (Diptera). The highest nesting incidence of 72.4 % was observed in the gallery forest, whereas only 27.6 % in the Cerrado; this difference in habitat use was significant (χ² = 5.56; p pollen types that belonged to six families. Pollen of the family Malpighiaceae was most frequently used, with four species represented (Byrsonima crassifolia, B. rotunda, B. spicata and Heteropterys sp.). C. dichrootricha showed a preference for nesting in cavities of various diameters in gallery forest sites. The present study provides a novel description of the nesting habits and biology of C. dichrootricha in habitats of Central/Southern Maranhão. C. dichrootricha primarily used resources from the Cerrado, including soil to build their nests, pollen and floral oils; we concluded that gallery forest and Cerrado areas are intrinsically related to the maintenance of local populations of this

    Abstract. The aim of this work was to identify behaviors of oil deposition by females of the solitary bee Centris analis (Fabricius parasitized by Physocephala spp. This study was conducted at the Campus of the University of São Paulo, Ribeirão Preto, using trap-nests in which the females built the brood-cells in nests made with black cardboard, introduced in wood blocks that were placed on two shelves at site of study. From the 26 females that nested in the area, 11 were found dead inside the empty trap-nests. Next, they were taken to the laboratory together with nine dead males, placed in glass tubes and were observed daily until the parasitoid Physocephala spp. (Diptera: Conopidae emerged. All nests built by the parasitized females had extra oil deposition on the last brood-cell occlusion. In addition, these females remained for 5.4 days at site of study after closing the nests, made extra oil depositions on the nest occlusions and closed 42 empty nests, without brood-cells. The data of this work suggest that the extra oil deposition by parasitized females, increase the difficulties to the success of the parasitoid Leucospis cayennensis Westwood, since there are 2 obstacles to be won: oil over the last partition and oil on the nest occlusion. It´s good to point out that defending the nests against parasitoids the females would be ensuring a new generation of conopids.

    Interoperability is a complex subject and often leads to different definitions in different environments. An interoperable framework of web services can improve the user experience by providing an interface for interaction with data regardless of it's format or physical location. This in itself improves accessibility to data, fosters data exploration and use, and provides a framework for new tools and applications. With an interoperable system you have: -- Data ready for action. Services model facilitates agile response to events. Services can be combined or reused quickly, upgraded or modified independently. -- Any data available through an interoperable framework can be operated on or combined with other data. Integrating standardized formats and access. -- New and existing systems have access to wide variety of data. Any new data added is easily incorporated with minimal changes required. The possibilities are limitless. The NOAA Earth Information System (NEIS) at the Earth System Research Laboratory (ESRL) is continuing research into an interoperable framework of layered services designed to facilitate the discovery, access, integration, visualization, and understanding of all NOAA (past, present, and future) data. An underlying philosophy of NEIS is to take advantage of existing off-the-shelf technologies and standards to minimize development of custom code allowing everyone to take advantage of the framework to meet these goals above. This framework, while built by NOAA are not limited to NOAA data or applications. Any other data available through similar services or applications that understand these standards can work interchangeably. Two major challenges are under active research at ESRL are data discoverability and fast access to big data. This presentation will provide an update on development of NEIS, including these challenges, the findings, and recommendations on what is needed for an interoperable system, as well as ongoing research activities

MÉTODOS: Estudo prospectivo composto de 30 pacientes com uveítes que foram divididos em dois grupos conforme a etiologia, infecciosa e não infecciosa, tendo sido aplicado duas vezes em cada paciente o questionário NEI-VFQ-25 que avalia a qualidade de vida relacionada à saúde geral e visual. RESULTADOS: A toxoplasmose foi a principal causa de uveíte infecciosa, enquanto a não infecciosa foi a síndrome de Vogt-Koyanagi-Harada. Quanto à qualidade de vida, a saúde geral é melhor no grupo de causa infecciosa, sendo que a saúde ocular é regular nos dois grupos. Apesar do déficit visual não provocar grandes distúrbios e restrições sociais, ambos os grupos apresentam comprometimento emocional importante, sendo que no grupo de causa não infecciosa, esse comprometimento gera grau maior de dependência para a realização de tarefas do cotidiano.

    In the frame of a co-operation agreement between Austrian Research Center Seibersdorf, Italian ENEA Institute for Radiation Protection and Hungarian KFKI Atomic Energy Research Centre, an intercomparison on WBC measurements using a modular bottle phantom was performed during 1995 in Hungary, on May-July 1996 in the Northern part of Italy. Results related to the relative bias for the three body masses are reported, together with indication of their compliance with ANSI report N13.30. It turned out that majority of the results were found to be within the performance criteria of the ANSI report, however there were also few outfalling results which were a good indication to check and improve the reliability of calibration and/or other methodological procedures. In the contrary of the expectance, the results related to 20 kg phantom resulted not significantly worse than those obtained for the adult phantom indicating the capacity for the participating WBC centres of measuring people from the general population. [Italiano] Nell`ambito di un accordo di collaborazione tra il Centro di Ricerca di Seibersdorf (Austria), l`Istituto per la Radioprotezione dell`ENEA (ENEA AMB PRO IRP) ed il Centro di Ricerca per l`Energia Atomica KFKI di Budapest (Ungheria), si e` svolto un interconfronto su misure WBC basato sull`utilizzo di un unico fantoccio modulare a bottiglie cui hanno partecipato centri WBC Ungheresi (1995) ed Italiani (Maggio-Giugno 1996). Nel presente rapporto tecnico vengono presentati i risultati ottenuti ed una loro analisi impostata sui criteri di valutazione recentemente proposti dall`ANSI nel rapporto N. 13.30. Sulla base di tale criterio la maggior parte dei risultati dell`interconfronto rientra nell`intervallo di accettabilita`; nei pochi casi di non accettabilita` si rende invece necessaria una revisione dei dati di calibrazione e delle metodologie. Contrariamente a quanto si poteva prevedere, i risultati relativi al fantoccio da 20 kg appaiono sostanzialmente

    The economically most important group of bees is the "corbiculates", or pollen basket bees, some 890 species of honeybees (Apis), bumblebees (Bombus), stingless bees (Meliponini), and orchid bees (Euglossini). Molecular studies have indicated that the corbiculates are closest to the New World genera Centris, with 230 species, and Epicharis, with 35, albeit without resolving the precise relationships. Instead of concave baskets, these bees have hairy hind legs on which they transport pollen mixed with floral oil, collected with setae on the anterior and middle legs. We sampled two-thirds of all Epicharis, a third of all Centris, and representatives of the four lineages of corbiculates for four nuclear gene regions, obtaining a well-supported phylogeny that has the corbiculate bees nested inside the Centris/Epicharis clade. Fossil-calibrated molecular clocks, combined with a biogeographic reconstruction incorporating insights from the fossil record, indicate that the corbiculate clade arose in the New World and diverged from Centris 84 (72-95)mya. The ancestral state preceding corbiculae thus was a hairy hind leg, perhaps adapted for oil transport as in Epicharis and Centris bees. Its replacement by glabrous, concave baskets represents a key innovation, allowing efficient transport of plant resins and large pollen/nectar loads and freeing the corbiculate clade from dependence on oil-offering flowers. The transformation could have involved a novel function of Ubx, the gene known to change hairy into smooth pollen baskets in Apis and Bombus. Copyright © 2014 Elsevier Inc. All rights reserved.

    Obiettivo: approfondire i rapporti tra carico lavorativo, personalità ed alcuni indicatori biochimici di risposta allo stress le cui modificazioni possono contribuire a spiegare la suscettibilità/resistenza al rischio di malattie.

     Materiali e metodi: l’indagine è stata effettuata su un gruppo di Vigili del Fuoco (n°61 confrontati con un gruppo di controllo (ricercatori universitari; entrambi hanno aderito tramite consenso informato e fornito un campione di saliva per la misura del cortisolo e delle IgA in condizioni di base. Un sottogruppo di vigili ha fornito anche un campione di saliva dopo un turno lavorativo notturno (condizione di stress. Parallelamente si è effettuato un assessment psicologico tramite la somministrazione di questionari quali: lo State-Trait Anxiety Inventory, il Big Five Observer, il Locus of Control ed il Sensation Seeking Scale. Risultati: in condizioni basali i Vigili del Fuoco mostrano un livello di cortisolo salivare più elevato dei controlli (24,9 ± 11,3 vs 20,0 ± 8,6 nmol/l, p=0,091, mentre il livello di IgA è simile nei due gruppi. Nei vigili, dopo lo stress lavorativo, si è evidenziato un calo significativo delle IgA (296,5 ± 160,5 vs 191,9 ± 95,3 Bg/ml, p=0,014 ed una correlazione positiva tra il cortisolo salivare e l’ansietà di stato e di tratto.

    Conclusioni: i Vigili del Fuoco sono risultati meno ansiosi, più predisposti al rischio e con un profilo di personalità di tipo realistico in linea con la scelta professionale. Lo stress lavorativo si associa ad una riduzione significativa dell’ escrezione salivare di IgA, assunta come indice di attività del sistema immunitario, mentre il cortisolo salivare, che rappresenta un indicatore sensibile di attività neuroendocrina sotto stress, pur non modificandosi in termini assoluti si associa con il livello di ansietà dei vigili allo studio.

    Full Text Available In generale, i grandi eventi sono considerati dalle città come la possibilità di realizzare nuove architetture e infrastrutture, per migliorare gli spazi pubblici e dare risonanza internazionale alla città stessa. In molte città contemporanee, la ristrutturazione economica e la riqualificazione urbana posto gli eventi al centro delle strategie di cambiamento.Spesso, tuttavia, questi interventi richiedono un tempo molto breve e investimenti elevati, che non sempre hanno un effetto duraturo nel tempo, con edifici e spazi che, dopo l'evento, si trasformano in spazi pubblici inutilizzati o edifici che devono essere riqualificati.Le città costiere rappresentano un campo privilegiato di analisi per approfondire le dinamiche dei processi di sviluppo e di rigenerazione connessi ad eventi.Alcune città hanno potenziato la propria identità marittima sviluppando attività legate alla vela, eventi sportivi velici e la nautica da diporto, promuovendo la crescita sociale ed economica, nonché la riqualificazione delle aree dismesse. Il recupero di questa identità è il punto di partenza per migliorare la qualità urbana e attrarre grandi eventi, sviluppando la competitività in un circolo virtuoso.L'immagine di queste città è migliorata, a livello locale, nazionale e internazionale, promuovendo processi di riqualificazione che hanno coinvolto i responsabili politici, gli utenti della città e gli stakeolders.Nei casi di successo, i grandi e i piccoli eventi rappresentano tessere di un mosaico più ampio, una visione della città fondata sulla identità marittima e il progetto di riqualificazione del waterfront è stato in grado di rafforzare le relazioni con le aree urbane esistenti.Il saggio propone due casi di studio europei, le città di Lorient e Valencia, mettendo in evidenza il ruolo della pianificazione a lungo termine nei processi di rigenerazione.La città di Lorient, in linea con la sua storia, ha iniziato un processo di rigenerazione

A first study, carried out in the 1996 by interviews, located a second group 3 km far, in Bogliasco locality. In this study, conducted in 2001-04, the population size of Genoa Nervi and the presence of the species in surrounding areas were investigated. In 2002 the population size was estimated in 115/286 individuals by distance sampling method, while, by direct observation, it varied from 80 individuals (2004 to 114 individuals (2003. The sampling by hair tubes in surrounding areas confirmed the presence of a group of grey squirrels in Bogliasco and excluded a further dispersal of the species. Riassunto In Liguria, la popolazione di Scoiattolo grigio Sciurus carolinensis ha avuto origine dall'introduzione di 5 coppie nei parchi urbani di Genova Nervi nel 1966. Un primo studio condotto nel 1996 ha localizzato, tramite interviste, un secondo nucleo a 3 km di distanza, in località Bogliasco. Il presente studio, condotto nel 2001-2004, è stato finalizzato alla valutazione della consistenza della popolazione nei parchi di Nervi, mediante il metodo distance sampling e osservazioni dirette, e all'accertamento della presenza della specie nelle aree circostanti mediante l'utilizzo di hair tube. La stima della popolazione con il metodo distance sampling è risultata di 115/286 individui nel 2002, mentre quella ottenuta mediante osservazioni dirette è variata da 80 individui nel 2004 a 114 individui nel 2003. Gli accertamenti compiuti nelle aree circostanti i parchi di Nervi hanno consentito di confermare la presenza di un nucleo di scoiattoli a Bogliasco e di escludere un'ulteriore espansione della specie.

    New cricetids (Eucricetodon wangae sp. nov., Eucricetodon sp. and Pappocricetodon siziwangqiensis sp. nov.) are reported from the lower and middle parts of the "Upper Red" beds of the Erden Obo section in Nei Mongol, China. Eucricetodon wangae is more primitive than other known species of the genus from lower Oligocene of Asia and Europe in having a single anterocone on M1, a single connection between the protocone and the paracone, the anterior metalophule connection in M1-2 and weaker anteroconid and ectomesolophid in lower molars. Pappocricetodon siziwangqiensis is more advanced than other species of the genus in permanently missing P4 and having posterior protolophule connection. These fossils suggest that the age of the "Upper Red" of the Erden Obo section is younger than the age of the Upper Eocene Houldjin and Caijiachong formations, but older than those containing the Shandgolian faunas; the "Upper Red" is most closely correlative to the Ergilian beds in age, and probably close to the Eocene/Oligocene boundary. Given the age estimate, Eucricetodon wangae provides the new evidence to support that cricetid dispersal from Asia to Europe occurred prior to the Eocene-Oligocene boundary.

    The treatment of children with life-threatening cardiac and cardiopulmonary failure is a large and underappreciated public health concern. We have previously shown that the CentriMag is a magnetically levitated centrifugal pump system, having the utility for treating adults and large children (1,500 utilized worldwide). We present here the PediVAS, a pump system whose design was modified from the CentriMag to meet the physiological requirements of young pediatric and neonatal patients. The PediVAS is comprised of a single-use centrifugal blood pump, reusable motor, and console, and is suitable for right ventricular assist device (RVAD), left ventricular assist device (LVAD), biventricular assist device (BVAD), or extracorporeal membrane oxygenator (ECMO) applications. It is designed to operate without bearings, seals and valves, and without regions of blood stasis, friction, or wear. The PediVAS pump is compatible with the CentriMag hardware, although the priming volume was reduced from 31 to 14 ml, and the port size reduced from 3/8 to (1/4) in. For the expected range of pediatric flow (0.3-3.0 L/min), the PediVAS exhibited superior hydraulic efficiency compared with the CentriMag. The PediVAS was evaluated in 14 pediatric animals for up to 30 days, demonstrating acceptable hydraulic function and hemocompatibility. The current results substantiate the performance and biocompatibility of the PediVAS cardiac assist system and are likely to support initiation of a US clinical trial in the future.

    Full Text Available Spesso origine dei primi insediamenti urbani, i corsi d’acqua sono stati nei secoli fonte di sostentamento per le popolazioni e strumento di scambio tra genti e culture. Proprio per il loro scorrere attraverso il territorio, essi sono per definizione luoghi di relazione, di intersezione tra diverse realtà urbane dove si incontrano ambiente, architettura, pianificazione, trasporti ma anche arte, cultura e turismo. Per questa loro caratteristica, le vie d’acqua rappresentano una grande potenzialità per lo sviluppo del territorio sia in termini di mobilità – di merci e di persone - che di turismo sostenibile. La loro riqualificazione permette di recuperare il ruolo di spazio pubblico e di paesaggio rurale, urbano e turistico di qualità; luoghi di fruizione turistica, culturale, gastronomica e sportiva, quindi di qualità della vita. Dopo decenni di oblio, sollecitata dal rinnovato interesse verso questi assi e anche dalle direttive dell’Unione Europee, l’Italia e, in particolare il Nord del paese, muove i primi passi verso la valorizzazione delle waterway a fini turistico-culturali, aprendo nuove possibilità di sviluppo del territorio. Sia pur con ritardo rispetto ad altri Paesi, che da anni e in diverse forme valorizzano e “sfruttano” le vie d’acqua, si avverte anche in Italia un cambio di mentalità che vede nell’uso e nel recupero di tale risorsa uno strumento importante per garantire la sostenibilità ambientale ed economica e il recupero di una identità culturale quasi dimenticata.

    , al fine di identificare le localizzazioni ottimali per disporre di un mercato di riferimento il più possibile esteso. Più specificamente, l’indicatore di accessibilità è stato definito in riferimento alla realizzazione della rete AV che collegherà Roma e Napoli in un tempo di 55 minuti. Pertanto, il sistema di aree per la localizzazione delle attività di eccellenza in ciascuna delle due polarità urbane considerate viene individuato ipotizzando un tempo massimo di percorrenza tra i due sistemi urbani pari a 90 minuti. Tale intervallo temporale si ritiene accettabile per il tipo di spostamenti connessi alle attività in esame: non si tratta, infatti, di spostamenti pendolari quanto, piuttosto, di una mobilità connessa alla fornitura di servizi altamente specializzati. Come ben evidenziato in una recente rassegna sul termine accessibilità, il tempo che si è disposti ad impiegare per raggiungere una data destinazione è, infatti, funzione del tipo di utenza e del tipo di attività o, più in generale, della convenienza per un dato individuo o per una data impresa (Litman, 2007. L’indicatore proposto tiene conto, oltre che del tempo di spostamento calcolato sulla rete su ferro sia nella tratta AV di connessione tra i due centri che nella tratta urbana della qualità del viaggio, considerando il numero e il tipo di scambi che è possibile effettuare sulla rete urbana, nell’arco temporale definito. L’applicazione dell’indicatore al sistema urbano integrato Roma-Napoli ha consentito l’individuazione, nelle due polarità urbane, di aree a diverso grado di “accessibilità” a partire dai due punti focali posti nelle stazioni AV e nell’arco temporale individuato e, conseguentemente, delle aree che, in ragione del solo parametro di accessibilità, risultano le più idonee per la localizzazione delle attività in esame.

Also, a compilation of the known host records for the species of Ericrocidini is presented and host-parasite associations are discussed. Host associations are known for seven of the 11 genera and about 17 of the 42 species of the tribe, involving a total of 34 confirmed or putative host species of Centridini bees. All species of the tribe are known to attack only nests of Centris Fabricius, 1804, except Mesoplia rufipes (Perty, 1833 that also parasitizes nests of Epicharis Klug, 1807. Although the phylogenetic relationships within Ericrocidini and among the subgenera of Centris are not well resolved, the current knowledge of the host-parasite associations points to a relatively high degree of specificity and possible coevolution between them.

  16. Transit Oriented Development: una soluzione per il governo delle aree di stazione

    Full Text Available I processi di diffusione e dispersione insediativa, la crescente crisi da congestione, la disponibilità di aree libere a seguito di dismissione di impianti industriali in aree strategiche della città, i consistenti investimenti in infrastrutture di trasporto su ferro in ambito urbano e regionale sono elementi chiave che hanno contribuito alla diffusione di teorie e pratiche per uno “sviluppo urbano orientato al sistema di trasporto pubblico su ferro”: il Transit Oriented Development- TOD. Questo termine, introdotto per la prima volta da Calthorpe nel 1993, sintetizza teorie e metodi volti a favorire uno sviluppo metropolitano policentrico i cui poli sono i Transit Villages ovvero comunità urbane ad alta densità e mixitè funzionale che si sviluppano intorno alle stazioni della rete su ferro. Nelle aree in espansione o in trasformazione il TOD propone la costruzione di nuovi centri urbani di elevata qualità urbana in aree della città consolidata il TOD prevede il riempimento dei vuoti esistenti ed interventi di riqualificazione urbana. Da molti anni si stanno mettendo in pratica questi principi prevalentemente negli Stati Uniti, dove la disponibilità di suoli e la necessità di limitare fenomeni di sprawl urbano hanno favorito la diffusione delle pratiche TOD in molte città. In Europa questo tipo di interventi non è ancora molto diffuso, a meno di alcuni casi specifici. L’articolo, partendo da queste premesse, vuole contribuire ad affrontare alcune questioni centrali: in quali modo è possibile “esportare” i metodi e le tecniche del TOD nelle città Europee e in particolare in Italia? Quali sono gli strumenti e le procedure per la definizione degli interventi? A partire da uno studio della letteratura scientifica e dall’analisi di casi di studio internazionali il paper propone alcune prime risposte attraverso una proposta di metodo per l’applicazione delle pratiche TOD nelle aree metropolitane italiane.

  17. Green economy: un'occasione per le aree montane

    Full Text Available È ormai opinione largamente condivisa che l’attuale “crisi” dell’organismo territoriale non sia soltanto economica ma anche ambientale. Quest’ultima tematica unita a quella della green economy potrebbero rappresentare l'occasione di intervenire sui sistemi territoriali non urbani, un tempo vitali per l’economia locale, ed oggi abbandonati a se stessi a favore delle aree urbanizzate, luoghi economicamente più vantaggiosi. Partendo dalle indicazioni del Programma per l’Ambiente delle Nazioni Unite (UNEP si potrebbero definire politiche di sviluppo al fine di migliorare la competitività e l'attrattività dei sistemi territoriali rurali attraverso la valorizzazione delle risorse endogene presenti su tali territori, con l’obiettivo di favorire lo sviluppo ecosostenibile delle diverse attività al fine di creare una rete integrata. La ricerca svolta presenta le diverse dinamiche legate alla creazione di una rete di Eco-Villaggi, con lo scopo di rifunzionalizzare il patrimonio edilizio e urbanistico esistente, migliorando, così, la qualità della vita dei centri montani. Questo modello può rappresentare concretamente una delle possibili soluzioni allo spopolamento, nel conservare e tutelare lo spazio naturale attraverso la promozione della green economy, basata sull’utilizzo di sistemi di produzione sostenibili, nel rispetto dei requisiti ambientali, nell’attivazione di sistemi energetici rinnovabili e nel richiamo turistico del patrimonio storico-culturale della montagna. Infatti queste risorse se gestite nel modo corretto, attraverso una attenta pianificazione territoriale, potrebbero rappresentare il volano per un modello di sviluppo sostenibile e allo stesso tempo potrebbero avviare una riqualificazione e valorizzazione dei borghi rurali, che spesso ospitano un patrimonio architettonico di notevole pregio. Risulta necessario, per i contesti rurali, porre in atto strumenti, modalità e forme innovative d’intervento capaci

    Full Text Available Nella città multiculturale le domande di città aumentano, i vari piani che caratterizzano e che intrecciandosi costruiscono e reinventano quotidianamente gli spazi urbani si moltiplicano e si fanno sempre più portatori di nuovi bisogni e domande di città che nascono dai cittadini che vivono gli spazi urbani. Nella letteratura sociologica si parla spesso della fine e della morte degli spazi pubblici nella città postmoderna, abbandonati, svuotati del loro significato e funzioni iniziali: quella dell’incontro e della socializzazione tra persone aventi status e biografie diverse. In realtà, gli spazi pubblici delle metropoli postmoderne non sono morti, si stanno trasformando e il loro significato e senso sono in continua evoluzione. Lo spazio della città è da sempre rappresentativo della società e del periodo storico che una popolazione sta attraversando e più che mai oggi ciò è vero con i vari flussi migratori che hanno abbattuto il vecchio concetto di confine, tipico dello Stato-Nazione, costruendone uno più ampio, fluido, aperto, poroso, simbolico e applicabile ad ogni visione in scala della città. Vediamo allora come gli spazi pubblici urbani sono tuttora molto frequentati, non più dagli autoctoni ma soprattutto dai migranti li riempiono con significati nuovi attraverso processi lunghi e densi di socialità.

    In order to research the infrared radiation characteristics of the skin covering Traditional Chinese acupuncture points, which are NeiGuan in the forearm and LaoGong in the center of the palm, we detected continuously the infrared radiation spectra of the human body surface by using Fourier Transform Infrared Spectroscopy. The experimental results showed that firstly, the differences of the infrared radiation spectra of the human body surface were obvious between individuals. Secondly, the infrared radiation intensity of the human body surface changed with time changing. The infrared radiation intensity in two special wavelength ranges (wavelengths from 6. 79 microm to 6. 85 microm and from 13. 6 microm to 14. 0 microm) changed much more than that in other ranges obviously. Thirdly, the proportions of the infrared radiation spectra changed, which were calculated from the spectra of two different aupuncture points, were same in these two special wavelength ranges, but their magnitude changes were different. These results suggested that the infrared radiation of acupuncture points have the same biological basis, and the mechanism of the infrared radiation in these two special wavelength ranges is different from other tissue heat radiation.

    indirizzare i pazienti alla biopsia ripetuta. Materiale e metodi. Abbiamo valutato i risultati di 72 biopsie ripetute in pazienti con una diagnosi di PIN ad una prima agobiopsia prostatica ecoguidata. A tutti e stato effettuato un numero minimo di 6 prelievi. Tutti avevano un PSA>4 ng/ml. Risultati. Sono stati rilevati alla biopsia ripetuta 15 adenocarcinomi su 50 pazienti (30%) con diagnosi iniziale di PIN a basso grado e 10 carcinomi su 22 (45,4%) con PIN ad alto grado. Sono stati diagnosticati 7 carcinomi in 18 pazienti (39%) nei quali il PSA era diminuito durante l'intervallo di osservazione, in 16 su 46 (35%) nei quali il PSA in aumento e 2 su 8 casi (25%) con PSA stabile. Conclusioni. I risultati sembrano confermare che il PIN puo essere considerato un precursore dell'adenocarcinoma prostatico o un'alterazione istologica frequentemente associata ad esso. I pazienti con diagnosi iniziale di PIN a basso grado e soprattutto quelli con PIN ad alto grado dovrebbero sistematicamente essere sottoposti a biopsia ripetuta a breve distanza per l'elevata frequenza di diagnosi finale di carcinoma. Non esistono ancora indicazioni condivise sull'intervallo temporale tra le due biopsie. Le variazioni del PSA che si possono riscontrare durante il periodo di osservazione non rappresentano un parametro statisticamente significativo per proporre o meno al paziente la ripetizione della biopsia prostatica.

    2012-02-01

    Full Text Available Quantification of the genetic distance between populations is essential in many genetic research programs. Several formulae were proposed for the estimation of genetic distance between populations using gene frequency data. But the selection of a suitable measure for estimating genetic distance between real-world human populations is a very difficult task despite the widely used measure Neis D. The present study was undertaken to estimate the genetic distance between Barak Valley Muslims (BVM and other twenty-four nations using seven different measures with ABO blood group gene frequency data for comparative analysis and to estimate the correlation coefficients between distance measures and to work out the linear regression equations. Seven genetic distance measures namely Neis D, Neis Nm, La, Neis Da, Dc, Re and Neis Ne were estimated between BVM and other 24 nations enroute the journey of mankind from Africa that commenced about 200,000 years ago (www.bradshawfoundation.com. Correlation coefficients between Neis D with other measures were estimated to find out which other genetic distance measures were closely related to Neis D. Neis D showed highly significant (p=0.01 positive correlation with Cavalli-Sforza and Edwards chord distance Dc (0.90, Reynolds Re (0.90, Neis Da (0.74 and Neis Ne (0.63 but negative correlation with Neis Nm and La. Linear regression equations of Neis D with other distance measures were estimated as Da = -0.80 + 1.34D, Dc = 1.91 + 4.44D, Re = -0.51 + 0.24D and Ne = -7.60 + 1.30D.

    In this work the stabilization of hazardous solid wastes containing heavy metals has been studied by means of novel matrices able to generate calcium trisulphoaluminate and silicate hydrates. The process is based on the hydration of two different mixtures containing blast furnace slag, coal ashes, chemical gypsum and Portland cement. The stabilization capacity of the two mixtures has been checked with regard to both a residue from an incinerator of municipal solid wastes and model systems obtained by adding 5 and 10% of soluble nitrates of Cd, Cr, Cu, Ni, Pb and Zn. The stabilized products have been validated from the point of view of mechanical properties by determining the unconfined compressive strength, and from the environmental point of view by means of static and dynamic leaching tests. Both matrices have proved to have great potentiality for the stabilization of hazardous solid wastes, the one based on blast furnace slag being better. Finally, evidence is given that different leaching tests are necessary to fully understand the immobilization mechanism responsible for stabilization. [Italiano] In questo lavoro e` stata studiata la atbilizzazione di residui tossici e nocivi contenenti metalli pesanti per mezzo di matrici leganti innovative capaci di generare trisolfoalluminato e silicato di calcio idrati.

Le capacita` stabilizzanti delle due miscele sono state verificate sia nei confronti di un residuo solido generato a seguito dell`incenerimento di RSU, che nei confronti di sistemi modello ottenuti aggiungendo singolarmente il 5 e 10% dei nitrati solubili di Cd, Cr, Cu, Ni, Pb e Zn. I prodotti solidi stabilizzati sono stati validati dal punto di vista delle prestazioni meccaniche mediante prove di resistenza a compressione, e dal punto di vista ambientale mediante test di rilascio sia statici che dinamici

    Because of the complexities associated with anticoagulation in temporary percutaneous ventricular assist device (pVAD) recipients, a lack of standardization exists in their management. This retrospective analysis evaluates current anticoagulation practices at a single center with the aim of identifying an optimal anticoagulation strategy and protocol. Patients were divided into two cohorts based on pVAD implanted (CentriMag (Thoratec; Pleasanton, CA) / TandemHeart (CardiacAssist; Pittsburgh, PA) or Impella (Abiomed, Danvers, MA)), with each group individually analyzed for bleeding and thrombotic complications. Patients in the CentriMag/TandemHeart cohort were subdivided based on the anticoagulation monitoring strategy (activated partial thromboplastin time (aPTT) or antifactor Xa unfractionated heparin (anti-Xa) values). In the CentriMag/TandemHeart cohort, there were five patients with anticoagulation titrated based on anti-Xa values; one patient developed a device thrombosis and a major bleed, whereas another patient experienced major bleeding. Eight patients received an Impella pVAD. Seven total major bleeds in three patients and no thrombotic events were detected. Based on distinct differences between the devices, anti-Xa values, and outcomes, two protocols were created to guide anticoagulation adjustments. However, anticoagulation in patients who require pVAD support is complex with constantly evolving anticoagulation goals. The ideal level of anticoagulation should be individually determined using several coagulation laboratory parameters in concert with hemodynamic changes in the patient's clinical status, the device, and the device cannulation.

    Full Text Available Nell’ambito del complesso e articolato quadro delle trasformazioni urbane, le città d’acqua – in molti casi, città portuali – hanno occupato, in questi ultimi decenni, un ruolo di assoluto protagonismo, dimostrando quanto la presenza dell’elemento acqua sia appetibile e funga da polo di attrazione per la qualità della vita di tutti i giorni. Il fenomeno della riqualificazione dei waterfront – ormai esteso ad una dimensione globale e che vede coinvolte le grandi città come quelle di medie e piccole dimensione in tutti i continenti – è in molti casi il vero punto di partenza e motore trainante dello sviluppo di intere porzioni di città – se non delle città stesse – riposizionandole in modo innovativo nel contesto internazionale. Il Centro Città d’Acqua di Venezia, alla luce dei suoi vent’anni di attività di monitoraggio e ricerca di ‘buone pratiche’ in questo ambito, intende porre l’accento sul tema della riqualificazione del waterfront, con particolare attenzione ad un’ottica internazionale, sviluppando al contempo un’analisi che tenga conto degli elementi di successo ma anche di alcuni punti di criticità di questo fenomeno. I casi-studio selezionati dimostrano, ciascuno con la propria specificità, come una convivenza sostenibile tra porto e città, sintetizzata nei 10 Principi per lo sviluppo sostenibile delle aree di waterfront urbano (Città d’Acqua, 2000, sia il cardine di una trasformazione allargata e condivisa da cui possano scaturire ricadute positive a scala urbana e territoriale.In the wide and complex panorama of urban transformation, waterfront revitalization is one of the most interesting phenomena of urban renewal of the last decades, bringing ‘cities on water’ around the world to a new leadership. After years of oblivion, the presence of the natural element –water – have shown to be of great appeal as an attractive pole for the quality of every day’s life. In particular, the

  11. NEIMiner: nanomaterial environmental impact data miner.

    As more engineered nanomaterials (eNM) are developed for a wide range of applications, it is crucial to minimize any unintended environmental impacts resulting from the application of eNM. To realize this vision, industry and policymakers must base risk management decisions on sound scientific information about the environmental fate of eNM, their availability to receptor organisms (eg, uptake), and any resultant biological effects (eg, toxicity). To address this critical need, we developed a model-driven, data mining system called NEIMiner, to study nanomaterial environmental impact (NEI). NEIMiner consists of four components: NEI modeling framework, data integration, data management and access, and model building. The NEI modeling framework defines the scope of NEI modeling and the strategy of integrating NEI models to form a layered, comprehensive predictability. The data integration layer brings together heterogeneous data sources related to NEI via automatic web services and web scraping technologies. The data management and access layer reuses and extends a popular content management system (CMS), Drupal, and consists of modules that model the complex data structure for NEI-related bibliography and characterization data. The model building layer provides an advanced analysis capability for NEI data. Together, these components provide significant value to the process of aggregating and analyzing large-scale distributed NEI data. A prototype of the NEIMiner system is available at http://neiminer.i-a-i.com/.

  20. Biochemical characterization and novel inhibitor identification of Mycobacterium tuberculosis Endonuclease VIII 2 (Rv3297

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Nei2 (Rv3297 is a DNA Base Excision Repair (BER glycosylase that is essential for survival of Mycobacterium tuberculosis in primates. We show that MtbNei2 is a bifunctional glycosylase that specifically acts on oxidized pyrimidine-containing single-stranded, double-stranded, 5’/3’ fork and bubble DNA substrates. MtbNei2 possesses Uracil DNA glycosylase activity unlike E. coli Nei. Mutational studies demonstrate that Pro2 and Glu3 located in the active site are essential for glycosylase activity of MtbNei2. Mutational analysis demonstrated that an unstructured C-terminal zinc finger domain that was important for activity in E. coli Nei and Fpg, was not required for the glycosylase activity of MtbNei2. Lastly, we screened the NCI natural product compound database and identified three natural product inhibitors with IC50 values ranging between 41.8 μM-92.7 μM against MtbNei2 in in vitro inhibition assays. Surface Plasmon Resonance (SPR experiments showed that the binding affinity of the best inhibitor, NSC31867, was 74 nM. The present results set the stage for exploiting this important target in developing new therapeutic strategies that target Mycobacterial BER.

  5. The oxidative DNA glycosylases of Mycobacterium tuberculosis exhibit different substrate preferences from their Escherichia coli counterparts.

    The DNA glycosylases that remove oxidized DNA bases fall into two general families: the Fpg/Nei family and the Nth superfamily. Based on protein sequence alignments, we identified four putative Fpg/Nei family members, as well as a putative Nth protein in Mycobacterium tuberculosis H37Rv. All four Fpg/Nei proteins were successfully overexpressed using a bicistronic vector created in our laboratory. The MtuNth protein was also overexpressed in soluble form. The substrate specificities of the purified enzymes were characterized in vitro with oligodeoxynucleotide substrates containing single lesions. Some were further characterized by gas chromatography/mass spectrometry (GC/MS) analysis of products released from gamma-irradiated DNA. MtuFpg1 has substrate specificity similar to that of EcoFpg. Both EcoFpg and MtuFpg1 are more efficient at removing spiroiminodihydantoin (Sp) than 7,8-dihydro-8-oxoguanine (8-oxoG). However, MtuFpg1 shows a substantially increased opposite base discrimination compared to EcoFpg. MtuFpg2 contains only the C-terminal domain of an Fpg protein and has no detectable DNA binding activity or DNA glycosylase/lyase activity and thus appears to be a pseudogene. MtuNei1 recognizes oxidized pyrimidines on both double-stranded and single-stranded DNA and exhibits uracil DNA glycosylase activity. MtuNth recognizes a variety of oxidized bases, including urea, 5,6-dihydrouracil (DHU), 5-hydroxyuracil (5-OHU), 5-hydroxycytosine (5-OHC) and methylhydantoin (MeHyd). Both MtuNei1 and MtuNth excise thymine glycol (Tg); however, MtuNei1 strongly prefers the (5R) isomers, whereas MtuNth recognizes only the (5S) isomers. MtuNei2 did not demonstrate activity in vitro as a recombinant protein, but like MtuNei1 when expressed in Escherichia coli, it decreased the spontaneous mutation frequency of both the fpg mutY nei triple and nei nth double mutants, suggesting that MtuNei2 is functionally active in vivo recognizing both guanine and cytosine oxidation products

  20. Cathalitic burners for residential gas appliances; Bruciatori catalitici di gas naturale per apparecchi domestici

    Energy Technology Data Exchange (ETDEWEB)

    2000-12-01

    The growing interest for the rational use of natural gas as a primary source of energy and for the reduction of pollutant emissions from combustion processes has kindled, in recent years, a widespread interest in studies and experimental investigations on the use of premix burners (either ceramic or metallic) for heat generators in domestic applications. The present paper deals with the R and D activities developed in this field by Italgas, Politecnico di Torino (Dipartimento di Scienza dei Materiali ed Ingegneria Chimica) and Merloni TermoSanitari, (an Italian gas boiler manufacturer). The technology hereby presented aims at reducing the pollutants emissions (CO, NO{sub x}, HC) in a wide range of working regimes of the burner, typical of residential heat appliances. The positive results in a lab scale experimental pilot plant have been in some cases confirmed in experimental runs performed on boiler prototypes suitable for large scale industrial production. Some projects, financially supported by the European Community and involving, beyond the above mentioned partners, also other gas distribution companies, universities, research institutes and burner manufacturers, are currently in progress to further analyse the performance of these burners. [Italian] Il crescente interesse per l'uso razionale del gas naturale quale fonte energetica primaria e quale combustibile a basso impatto ambientale, ha suscitato, nei tempi piu' recenti, un vasto interesse per gli studi e per le ricerche nel settore dei bruciatori di gas di tipo a premiscelazione, siano essi in materiale ceramico che metallico, allo scopo di rendere praticabile la loro applicazione nei generatori di calore di tipo domestico. L'articolo descrive l'attivita' di R e S sviluppata da Italgas, Politecnico di Torino - Dipartimento di Scienza dei Materiali ed Ingegneria Chimica - e da Merloni TermoSanitari.

    The genus Cyrtopodium comprises about 42 species distributed from southern Florida to northern Argentina. Cyrtopodium polyphyllum occurs on rocks or in sandy soils, in restinga vegetation along the Brazilian coast. It flowers during the wet season and its inflorescences produce a high number of resupinate yellow flowers. Cyrtopodium polyphyllum offers no rewards to its pollinators, but mimics the yellow, reward-producing flowers of nearby growing Stigmaphyllon arenicola (oil) and Crotalaria vitellina (nectar) individuals. Several species of bee visit flowers of C. polyphyllum, but only two species of Centris (Centris tarsata and Centris labrosa) act as pollinators. Visits to flowers of C. polyphyllum were scarce and, as a consequence, low-fruit set was recorded under natural conditions. Such low-fruit production contrasts with the number of fruits each plant bears after manual pollination, suggesting deficient pollen transfer among plants. C. polyphyllum is self-compatible and has a high-fruit set in both manual self- and cross-pollinated flowers. Furthermore, fruits (2%) are formed by self-pollination assisted by rain. This facultative self-pollination mechanism is an important strategy to provide reproductive assurance to C. polyphyllum as rainfall restricts the foraging activity of its pollinating bees. Fruits derived from treatments and under natural conditions had a similar high rate of potentially viable seed. Moreover, these seeds had a low polyembryony rate, which did not exceed 5%. C. polyphyllum acts by deceit involving optical signals and exploits other yellow-flowered species within its habitat by attracting their pollinators. The low capsule production under natural conditions was expected, but its reproductive success is assured through self-pollination by rain and high seed viability.

    Full Text Available The paper deals with the theme of design responsibilities. This paper starts from a description of the role played by architects, landscape architects and urban designers in landscape changes. This role assumes the character of specific responsibility that is different from that played by public officials, or single citizen. A designer, in order to face landscape changes, need to deal consciously with three responsibilities: the species responsibility, the generation responsibility and the competence responsibility. Specie and generation responsibilities force us, as human beings, to balance our actions with the heritages left by who lived before. The competence responsibility drives us, as architects, towards a forced choice and the design authority gives us the expertise to accomplish this duty.The paper is closed by a description of six strategies on urban edges, inspired by designs and project implemented al local level both in Europe an in North-America.

    Multiple Spurious Operation(MSO) scenarios should contain scenarios threatening Post-fire safe shutdown function by MSO of Safe Shutdown Equipments(SSEs) as well as Non-SSEs. The list of MSO generic scenarios(NEI 00-01, Appendix G) was developed by industrial survey. Although not all scenarios of the list of MSO generic scenarios(NEI 00-01, Appendix G) are considered applicable to every reactor type, this list provides an input about MSO identification and treatment process. If NEI 00-01 is applied to other reactor type, analyst should review applicability of the list of generic scenarios(NEI 00-01, Appendix G) and consider potential MSO scenarios undescribed in the list of MSO generic scenarios(NEI 00-01, Appendix G). Especially, in PHWR case, there is no list of MSO generic scenarios in Canada or internationally. There are substantial physical variations between NPPs. So some generic scenarios(NEI 00-01, Appendix G) would need validation. Nevertheless, industrial stakeholder have not did any MSO work until now. In this paper, results of first stage research that develop the list of MSO generic scenarios for pressurized heavy water reactor(PHWR) is introduced. According to the review results, specific review of the list of MSO generic scenarios(NEI 00-01, Appendix G) is required such as how it applies to PHWR. And criteria was established for review of availability of the list of generic scenarios(NEI 00-01, Appendix G). However there are still many tasks such as potential scenario review, risk model review and expert panel review.

    Previously, a linear relationship has been found between net energy intake (NEI) and dietary chewing index (CI) of the diet for different types of cattle. Therefore, we propose to generalize and calibrate this relationship into a new model for direct prediction of NEI by dairy cows from CI values...... a value of 2, implying a constant maximum daily chewing time. The intercept NEI0 in the regression of NEI on CINE may be interpreted as metabolic net energy intake capacity of the cows fed without physical constraints on intake. Based on experimental data, the maximum chewing time was estimated as 1...

    Full Text Available Nella nota vengono sintetizzate le principali conclusioni cui è pervenuta una ricerca finanziata dalla Camera di Commercio di Napoli e realizzata da Uniontrasporti e dal dipartimento di Ingegneria dei trasporti della Federico II. Il lavoro ha riguardato il settore prevalente della city logistics e cioè il rifornimento di quegli esercizi della rete commerciale al dettaglio che non dispongono di organizzazioni autonome già oggi sotto controllo come, ad esempio, hanno la Grande distribuzione, il trasporto dei giornali, dei prodotti farmaceutici, degli ortofrutticoli ecc. Il lavoro è stato caratterizzato da alcune specificità: • è basato su una conoscenza quantitativa diretta della domanda di rifornimento merci nell’area metropolitana di Napoli ottenuta da una rilevazione campionaria sul campo (2000 interviste • si riferisce ad un’area metropolitana e non ad una singola città, prevedendo che una diversa organizzazione del rifornimento deve riguardare tutti gli esercizi del territorio sul quale operano le aziende del settore, territorio che, per le grandi città, coincide con l’area metropolitana • prevede la realizzazione di due tipologie di “nodi” nei quali effettuare manipolazione delle merci: centri merci inseriti negli interporti dell’area per i flussi provenienti o destinati in zone molto distanti (Italia del centro, del nord e del sud e transit point “di quartiere” dai quali partire per raggiungere il destinatario finale con mezzi a mano o ad emissione zero o anche con ritiro a cura del destinatario stesso. Le principali dimensioni della domanda desunte dall’indagine eseguita possono essere sintetizzate nelle seguenti cifre: 27.000 consegne/giorno-medio (0,87 per esercizio per 260.000 colli (9,72 a consegna su tutto il territorio della provincia; il 44% destinate alla città di Napoli, il 45% destinato al resto dell’area metropolitana di Napoli e l’11% al resto della provincia; il 34% proviene invece da

    Since 1995 the European Commission, through the SAVE programme, and the Economic Commission for Europe of the United Nations, through the Energy Efficiency 2000 Project, jointly sponsored the so called SACHA projects in Central and Eastern European Countries regarding major household appliances. Consistently, the main objective of the projects was to analyse and interpret the situation of refrigerators, freezers and washing machines in seven CEEC, so as to increase the knowledge and understanding of the issues at stake in the area of energy efficiency and environmental friendliness, and therefore to identify possible scenarios of improvement. This paper describes the work accomplished and the results achieved in this context, focusing more on the data collection and market survey moments and illustrates, with an abundant series of exhibits, the quantitative picture resulting form the analyses carried out. Possibility exists for replication in Latin America, where ENEA and Italian experience could be fruitfully applied. Reliable and complete information is in fact one of the prerequisites to overcome potential barriers and facilitate a successful enforcement of any energy efficiency policy. Effective implementation and regional harmonisation are necessary, even if projects can facilitate the fulfilment of these goals as it provides a consolidated methodology and an integrated scheme for basic data collection and analysis. [Italian] A partire dal 1995 la Commissione Europea e la Commissione Economica per l'Europa delle Nazioni Unite hanno congiuntamente promosso lo studio dei piu' importanti apparecchi domestici nei paesi dell'Europa centrale ed orientale.

    Directory of Open Access Journals (Sweden)

    Luisa Bravo

    2008-12-01

    Full Text Available The concept of “historical centre”, intended as the extended urban area, is introduced, from a regulatory standpoint, immediately after the postwar period, when it is more strong the need to provide for the reconstruction and preservation of the city. The city planning tool, developed by national legislation, for the definition of plans aimed at recovering the historical values of the urban landscape goes through the evolution of the concept of historical center and lives on the contribution of critical studies and researches from Astengo and Cavallari Murat, who explored the theme of the story of planning and method of representation. At the regional level, the Emilia-Romagna, beginning from the Conservation plan for the historical center of Bologna, presented in 1969, develops a strong body of legal substance, the result of critical reprocessing of the national debate, and contributes significantly to enhance themes of urban landscape and its regeneration.

    The paper describes an Integrate Source Collection System applied to municipal solid waste, through: introduction of source collection methodologies of the organic fraction (FORSU), of the co-mingled recyclable fraction (RDM) and of the no-recyclable fraction (remaining part), realization of structures (transfer station) able to optimize the sorting and the transportation of the different fraction. The main principle followed interprets the differential collection no longer as an additional service (which would mean an increase in cost) but a substitutive service to the normal one (where the increase in cost is compensated by a reduction of cost referent to no-recyclable fraction). The objects of the studied system: increasing of the collection aimed to recover and recycling minimizing managing cost; have been carried out through an experimental application. Moreover the optimization of the collection routes, reached using numerical computing is presented. [Italian] Nel presente lavoro si descrive l'applicazione di un servizio di raccolta integrale dei RSU tramite: l'introduzione delle metodologie di raccolta Umido (Frazione Organica dei Rifiuti Solidi Urbani), Secco Riciclabile (Raccolta Differenziata Multimediale) e Secco Non Riciclabile (Indifferienziato), la realizzazione delle strutture necessarie al suo funzionamento ed alla sua razionalizzazione economica (Stazione di Trasferenza). La metodologia proposta presenta un carattere fortemente innovativo. Il principio generale seguito interpreta la raccolta indifferenziata non piu' come servizio aggiuntivo (quindi con incremento dei costi in funzione dell'incremento dei servizi relativi), ma come sistema sostitutivo al normale servizio (incremento dei costi compensato dalla riduzione dei costi relativi alla frazione indifferenziata sia in temini di smaltimento che di raccolta).

    Dose assessment in internal dosimetry needs computational and interpretative tools that allow carrying out, as a first step, an evaluation of intake on the base of bioassay measurements or WBC measurements, and as a second step, dose evaluation on the base of estimated intake. In the frame of the MIDIA Co-ordination (WBC operating in Italy), in the first months of 1997 a census on methodologies for dose evaluation in internal contamination has been proposed. A technical form has been sent to all the WBC Centres allowing an accurate description of modalities used in each centre. 9 out of 17 centres sent the answers to the technical form in time. In this paper all the forms filled in are reported. A careful comparative evaluation of the answers has been made both for routine monitoring and for special monitoring. The various radionuclides present in the Italian reality, calculation methodologies both for intake and dose, hypotheses adopted for date, path and modalities of contaminations are also presented. Proposals for conforming to the methodology in Italy after the introduction of the models following ICRP 60 publication that are the base of the Euratom 96/29 Directive are also discussed. [Italiano] La valutazione di dose in contaminazione interna necessita di strumenti interpretativi che permettano di effettuare in una prima la valutazione dell`intake sulla base delle misure dei campioni biologici o del corpo intero (WBC), ed in una seconda fase la valutazione della dose sulla base dell`intake.

Ai diversi centri e` stato inviato una scheda tecnica che, mediante un particolareggiato schema di domande, aiutava i diversi centri nella esposizione delle modalita` di valutazione di dose che ogni centro segue. 9 au 17 centri WBC operanti al momemnto in Italia hanno inviato la

  7. Not carbon neutral: Assessing the net emissions impact of residues burned for bioenergy

    Science.gov (United States)

    Booth, Mary S.

    2018-03-01

    Climate mitigation requires emissions to peak then decline within two decades, but many mitigation models include 100 EJ or more of bioenergy, ignoring emissions from biomass oxidation. Treatment of bioenergy as ‘low carbon’ or carbon neutral often assumes fuels are agricultural or forestry residues that will decompose and emit CO2 if not burned for energy. However, for ‘low carbon’ assumptions about residues to be reasonable, two conditions must be met: biomass must genuinely be material left over from some other process; and cumulative net emissions, the additional CO2 emitted by burning biomass compared to its alternative fate, must be low or negligible in a timeframe meaningful for climate mitigation. This study assesses biomass use and net emissions from the US bioenergy and wood pellet manufacturing sectors. It defines the ratio of cumulative net emissions to combustion, manufacturing and transport emissions as the net emissions impact (NEI), and evaluates the NEI at year 10 and beyond for a variety of scenarios. The analysis indicates the US industrial bioenergy sector mostly burns black liquor and has an NEI of 20% at year 10, while the NEI for plants burning forest residues ranges from 41%-95%. Wood pellets have a NEI of 55%-79% at year 10, with net CO2 emissions of 14-20 tonnes for every tonne of pellets; by year 40, the NEI is 26%-54%. Net emissions may be ten times higher at year 40 if whole trees are harvested for feedstock. Projected global pellet use would generate around 1% of world bioenergy with cumulative net emissions of 2 Gt of CO2 by 2050. Using the NEI to weight biogenic CO2 for inclusion in carbon trading programs and to qualify bioenergy for renewable energy subsidies would reduce emissions more effectively than the current assumption of carbon neutrality.

    2015-08-01

    To assess the vision-related quality of life (QOL) in a cohort of patients with ocular graft-versus-host disease (GVHD). Prospective study. Eighty-four patients diagnosed with chronic ocular GVHD. We assessed the vision-related QOL with the 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ-25). The symptoms of ocular GVHD were assessed using the Ocular Surface Disease Index (OSDI) and Symptom Assessment in Dry Eye (SANDE) questionnaires. We assessed vision-related QOL with the NEI-VFQ-25 and compared the scores obtained from patients with ocular GVHD with those from a healthy population. In the ocular GVHD population, we also evaluated the associations between the NEI-VFQ-25 and the dry eye symptoms measured by the OSDI and SANDE questionnaires, age, duration of disease, best-corrected visual acuity (BCVA), corneal fluorescein staining (CFS), tear break-up time, and Schirmer test. The mean composite NEI-VFQ-25 score in patients with ocular GVHD was 76.5±17. Compared with healthy subjects, patients with ocular GVHD reported reduced scores on all NEI-VFQ-25 subscales (each P vision (P = 0.11). The NEI-VFQ-25 composite scores significantly correlated with OSDI (R = -0.81, P vision-related QOL. This study highlights the impact of ocular GVHD on the vision-related QOL, and thus the importance of comprehensive diagnosis and treatment of this condition.

    Purpose of this work is to evaluate the relationship of systolic and diastolic function at rest to exercise capacity. Seventeen patients with ischemic heart failure were included in the study. Ambulatory left ventricular monitoring at rest and during upright exercise with combined analysis of pulmonary gas exchange was performed. Ejection fraction, end-diastolic volume, end-systolic volume, stroke volume, cardiac output, and peak filling rate were measured. Significant positive correlations were found between rest ejection fraction and peak oxygen consumption (r=.60, p<.01), peak cardiac output (r=.67, p<.005). On the other hand, peak filling rate at rest showed a significant inverse correlation with peak end-diastolic (r=.48, p<.05) and end-systolic (r=-.66, p<.005) volumes. The patients were then sub grouped into two groups according to their rest ejection fraction (lower or higher than 40%). In the group with ejection fraction less than 40% a significant correlation was observed between rest ejection fraction and both peak stroke volume (r=-.66, p<.05) and peak ejection fraction (r=.69, p<.05). In the same group of patients an inverse correlation was found between peak filling rate and both end-diastolic (r=.65, p<.05) and end-systolic (r=.82, p<.005) volumes. The results of the present study suggest that exercise capacity is related to left ventricular function at rest and that rest diastolic function might be a determinant of left ventricular function during exercise in patients with heart failure.

  11. Inovação, economia dos custos de transação e gestão da cadeia de suprimento: uma discussão teórica

    Directory of Open Access Journals (Sweden)

    Manoela Silveira dos Santos

    2014-07-01

    Full Text Available O artigo realiza uma discussão teórica acerca da inovação, sob a ótica da Nova Economia Institucional (NEI e da Gestão da Cadeia de Suprimento (GCS. Levantamos uma importante e atual discussão sobre o papel da inovação nas cadeias de suprimento e evidenciam-se alguns pontos frágeis da NEI. Questionamos como a inovação pode ser relacionada aos principais conceitos referentes à NEI e à GCS? Tomamos como base o conceito de inovação trabalhado pela Abordagem Evolucionista. A aproximação dos elementos dessa teoria vinculados à inovação, à SCM e aos elementos fundamentais da NEI possibilita sublinhar o importante papel das instituições não só para a NEI e para a GCS, mas também para a Abordagem Evolucionista. As instituições, além de contribuírem para a coordenação das ações dos membros da cadeia, impactando diretamente sua estrutura e seu desempenho nas transações que ocorrem entre eles, afetam a capacidade da cadeia ou da firma gerar inovações.

  16. TRAP-NESTING BEES AND WASPS (HYMENOPTERA, ACULEATA IN A SEMIDECIDUAL SEASONAL FOREST FRAGMENT, SOUTHERN BRAZIL

    Directory of Open Access Journals (Sweden)

    PRISCILA S. OLIVEIRA

    Full Text Available ABSTRACT Trap-nesting bee and wasp inventories are common in Brazil but many phytophysiognomies are still poorly studied. The main objective of this study is to survey trap-nesting bees and wasps in a Semidecidual Seasonal Forest fragment. Also, we test the differences on nesting between interior and edge transects. A sum of 1,500 trap nests was made with bamboo cane internodes and two consecutive years were monitored. In the first year 46 nests were occupied by Pachodynerus grandis (19 nests, Pachodynerus guadulpensis (19, Centris analis (two, and Centris tarsata, Megachile fiebrigi, Megachile guaranitica, Megachile susurrans, Trypoxylon sp and Zethus smithii with one nest each. No statistical differences were found between interior and edge transects for richness and occupation rate, but the species composition was different. In the second year 39 nests were occupied by four species, three previously recorded, C. analis (seven nests, P. guadulpensis and P. grandis (six nests each, plus Monobia angulosa with 15 nests. Parasitoids from four families and one cleptoparasite were recorded and the mortality rate was higher in bees than in wasps. These findings reinforce the notion that trap nests assemblages from different studies are not directly comparable for richness and composition.

  2. Etica ed estetica dell’abitare. Paesaggio globale e territori urbani

    Directory of Open Access Journals (Sweden)

    Raffaele Milani

    2015-12-01

    Full Text Available The city, which is the outcome of history, culture and civilization, at first sight reveals itself to us like an exaltation of the act of building in a game of forms and volumes, or like a glorification of architecture; subsequently it is perceived also as a sign of the community and of the belonging that the forms reflect. What we see, while rethinking its meaning, from ancient times to modernity, is a complex human making, the extraordinary design of collective and individual action, the effect of an art of the extended space. It interacts with what is called the art of landscape, because it proposes elements of care, of imagination and of planning, the signs of creativity and the creations of necessity. Like an activity where the man is the creator of plantations, we can say indeed that there is an art of the city as a product of communities and the individuals, of architects and artists, of planners and simple workers, of citizens and their political representatives: it is the outcome of an ideal and civil effort, but also of a concrete, multifaceted manifestation of the techniques in the space, something which is also shaped, time after time, by that given social group or by ideologies.

  3. Grandi Eventi: indicatori di classificazione e incidenza sui sistemi urbani

    Directory of Open Access Journals (Sweden)

    Giuseppe Mazzeo

    2008-08-01

    Full Text Available I grandi eventi sono ritenuti una opportunità per le città in quanto sono uno straordinario catalizzatore di investimenti mirati alla trasformazione della città. L’azione dei grandi eventi non è confinata solo nel periodo di svolgimento dell’evento stesso ma si estende ad un periodo molto più ampio, prima e, soprattutto, dopo il suo termine. Nell’organizzazione delle manifestazioni più recenti le trasformazioni urbane hanno interessato in modo sempre maggiore parti già in precedenza urbanizzate, al punto che l’evento diviene l’occasione per trasformare la città costruita e per modificarne il profilo. Il paper approfondisce l’argomento della classificazione degli eventi e del loro impatto sul sistema urbano sviluppandosi in tre parti. Nella prima si analizzano due tipologie di grandi eventi (le esposizioni internazionali e i giochi olimpici con l’obiettivo di pervenire ad una definizione condivisa. Nella seconda parte si identificano i più importanti fattori ed indicatori per l’analisi di questa specifica categoria di avvenimenti. Infine, nella terza parte, si approfondiscono i fattori connessi all’impatto sul sistema urbano e all’organizzazione della sua mobilità. In particolare, viene approfondito il concetto di “effetto pulsar”, ossia gli effetti moltiplicativi sulla evoluzione urbana dipendenti dalla organizzazione di eventi multipli in parallelo o in sequenza. Uno degli elementi più negativi connessi alla organizzazione di un grande evento è la dispersione nel tempo dei benefici acquisiti grazie ad esso; per evitare ciò è necessario che l’evento sia seguito da politiche strategiche continue in modo da preservare i vantaggi acquisiti.

Despite the differences between the geo-cultural contexts, it is a phenomenon that goes hand in hand with extremely significant growth rates experienced by emerging economies over the last decade. Dealing with the specific characteristics of the middle classes in BRIC(S countries means facing with a matter of the global future in terms of both economic prospects and international relationship. In this paper we are going to reconstruct firstly an operational definition of middle class concept in emerging economies, as well as defining criteria and drafting their future evolution. Secondly we are going to examine the articulation of the middle class in each BRIC(S countries (Asia, South America and the Caribbean, Africa, Russia. Finally, we are going to mention the social policies necessary to maintain and develop the standard of living achieved: public expenditures in health and education as well as infrastructural investment.

    Full Text Available Scopo del presente lavoro è stato quello di testare la sensibilità antibiotica di 60 ceppi di Salmonella (S. enteritidis, S. typhimurium, S. gallinarum isolati da galline ovaiole nel periodo compreso tra il 2000 e il 2003. S. gallinarum mostrava resistenza nei confronti di ciprofloxacina ed enrofloxacina (rispettivamente 15% e 23%, al contrario di S. enteritidis e S. typhimurium che manifestavano una completa sensibilità. Tutti i sierotipi valutati presentavano alte percentuali di resistenza nei confronti di neomicina, gentamicina e ossitetraciclina. Nei confronti dei sulfamidici i ceppi testati presentavano resistenza nulla. Tali risultati suggeriscono un uso più moderato e mirato degli antibiotici negli allevamenti in modo da ridurre la selezione e diffusione di ceppi multiresistenti.

    The market for CANDU reactor sales, both international and domestic, is reviewed. It is reasonable to expect that between five and ten reactors can be sold outside Canada before the end of the centry, and new domestic orders should be forthcoming as well. AECL International has been created to market CANDU, and is working together with the Canadian nuclear industry to promote the reactor and to assemble an attractive package that can be offered abroad.

    2012-01-01

    Full Text Available A study of genetic variation among 10 pairs of chromosomes extracted from 13 tropical sweet corn inbred lines, using 99 microsatellite markers, revealed a wide range of genetic diversity. Allelic richness and the number of effective alleles per chromosome ranged from 2.78 to 4.33 and 1.96 to 3.47, respectively, with respective mean values of 3.62 and 2.73. According to the Shannon's information index (I and Nei's gene diversity coefficient (Nei, Chromosome 10 was the most informative chromosome (I = 1.311 and Nei = 0.703, while Chromosome 2 possessed the least (I = 0.762 and Nei = 0.456. Based on linkage disequilibrium (LD measurements for loci less than 50 cM apart on the same chromosome, all loci on Chromosomes 1, 6 and 7 were in equilibrium. Even so, there was a high proportion of genetic variation in Chromosomes 4, 5, 8, 9 and 10, thereby revealing their appropriateness for use in the genetic diversity investigations among tropical sweet corn lines. Chromosome 4, with the highest number of loci in linkage disequilibrium, was considered the best for marker-phenotype association and QTL mapping, followed by Chromosomes 5, 8, 9 and 10.

    To evaluate longitudinal vision-related quality of life (VRQoL) in patients with noninfectious uveitis. Cohort study using randomized controlled trial data. Patients with active or recently active intermediate uveitis, posterior uveitis, or panuveitis enrolled in the Multicenter Steroid Treatment Trial and Follow-up Study. Data from the 25-item National Eye Institute Visual Functioning Questionnaire (NEI-VFQ-25) for the first 3 years after randomization were evaluated semiannually. Analyses were stratified by assigned treatment (129 implants vs. 126 systemic therapies) because of substantial differences in the trajectories of VRQoL. The impact of baseline measurements of visual function (visual acuity and visual field), demographics, and disease characteristics was assessed using generalized estimating equations. Primary outcome was the NEI-VFQ-25 composite score over 3 years after randomization. Individuals in both treatment groups showed similar improvement in NEI-VFQ-25 scores after 3 years of follow-up (implant: 11.9 points; 95% confidence interval [CI], 8.6-15.2; P treatment groups. In the systemic group, these differences were maintained throughout follow-up. In the implant group, individuals with initial visual acuity worse than 20/40 showed additional improvement in NEI-VFQ-25 score to come within -7 points (95% CI, -15.0 to 0.9) of those with visual acuity 20/40 or better initially, a clinically meaningful but not statistically significant difference (P = 0.081). Results based on sensitivity analyses showed similar patterns. Both treatment groups demonstrated significant improvements in NEI-VFQ-25 scores; however, the improvement was immediate for the implant group as opposed to gradual for the systemic group. Poorer visual function was associated significantly with initial differences in NEI-VFQ-25 scores. However, only individuals in the implant group with poor visual acuity were able to overcome their initial deficits by the end of 3 years

  7. PROGRAMMAZIONE STRATEGICA E VALUTAZIONE GENERATIVA NELLA RIQUALIFICAZIONE DEI TESSUTI URBANI STORICI

    Directory of Open Access Journals (Sweden)

    Vittoria Ventura

    2016-06-01

    Full Text Available The old town of Ragusa is undertaking a process of progressive urban enhancement in some different directions. Its differently valued parts should be covered by a general valorization strategy connecting the decision making process with functional and symbolic values that need to be adequately analyzed and represented. In such a multi-layered urban sub-system, the Architectural Unit can play the role of main information/value unit from which the valuation/decision making pattern starts. The proposed pattern includes, connects and systematizes the analysis, valuation and planning stages by coordinating quantitative appraisals and qualitative multi- criteria assessments based on a MAVT pattern. In particular, the planning stage is aimed at associating the fair Intervention Category to each Architectural Unit by generating a great number of overall intervention strategies in order to maximize different and conflicting objectives. Thus, the strategies are compared basing on their axiological profile, to lay down a trade-off scheme between them. The pattern endorses a semiotic interpretation of the urban fabric, sorting the single Architectural Units by signs, symbols and icons.

    Full Text Available The paper aims to reflect critically on some patterns due to the semantic concept of crisis, focusing on the centrality they have assumed in social sciences and on the various interpretations of social changes started by the modernization process, with reference to urban settings. It pays particular attention to the nature of the concept of crisis as a 'concept-process'. Time passing by, such definition has been affected by the intellectual speculation and the sequence of national and international events, from cultural, economic, political and social matrix.

  9. Un ponte metropolitano a Napoli - Capodichino

    Aldo di Chio

    2011-02-01

    Full Text Available Uno dei temi più dibattuti in riferimento al passaggio di una nuova infrastruttura in un paesaggio, più o meno antropizzato, riguarda i rischi della possibile di¬struzione di quest’ultimo. Alcune volte, però, questi interventi costituiscono una vera e propria occasione per riqualificare ambiti urbani degradati anche estesi. In questo spirito si è operato con il progetto del completamento di un ponte, rimasto incompiuto per quasi cinquanta anni a Napoli, in un quartiere che nel tempo ha perso identità e ruolo urbani, fino al completo degrado fisico e sociale. Il progetto di completamento dell’asse di collegamento tra lo svincolo Napoli-est della tangenziale, il quartiere 167 di Secondigliano e la Circumvallazione esterna prevede la costruzione del collegamento con Viale Comandante Umberto Maddalena a partire dall’attuale interruzione dell’opera in corrispondenza della spalla D esistente e la sistemazione delle aree esterne pertinenziali. Questo asse di primaria importanza per la viabilità cittadina insiste su un’area sensibile della città, per storia e morfologia, e può rappresentare una concreta occasione di recupero di essa, recupero urbano e recupero funzionale, con effetti indotti positivi che si irradiano all’intero quartiere e oltre. L’obiettivo del progetto proposto é far si che il completamento del ponte esistente rappresenti un elemento di qualità urbana, oltre che la tessera mancante di un importante mosaico di viabilità metropolitana. In questo senso il ponte può diventare un prezioso elemento del paesaggio urbano metropolitano.

    Full Text Available The emergence of severe acute respiratory syndrome (SARS in 2002 and 2003 affected global health and caused major economic disruption. Adequate animal models are required to study the underlying pathogenesis of SARS-associated coronavirus (SARS-CoV infection and to develop effective vaccines and therapeutics. We report the first findings of measurable clinical disease in nonhuman primates (NHPs infected with SARS-CoV.In order to characterize clinically relevant parameters of SARS-CoV infection in NHPs, we infected cynomolgus macaques with SARS-CoV in three groups: Group I was infected in the nares and bronchus, group II in the nares and conjunctiva, and group III intravenously. Nonhuman primates in groups I and II developed mild to moderate symptomatic illness. All NHPs demonstrated evidence of viral replication and developed neutralizing antibodies. Chest radiographs from several animals in groups I and II revealed unifocal or multifocal pneumonia that peaked between days 8 and 10 postinfection. Clinical laboratory tests were not significantly changed. Overall, inoculation by a mucosal route produced more prominent disease than did intravenous inoculation. Half of the group I animals were infected with a recombinant infectious clone SARS-CoV derived from the SARS-CoV Urbani strain. This infectious clone produced disease indistinguishable from wild-type Urbani strain.SARS-CoV infection of cynomolgus macaques did not reproduce the severe illness seen in the majority of adult human cases of SARS; however, our results suggest similarities to the milder syndrome of SARS-CoV infection characteristically seen in young children.

His theory flourished for a time, then drifted to the fringe of medical practice before re-emerging in the mid-1990s as a concept worthy of mainstream medical attention. Metchnikoff also predicted the existence of bacterial translocation and anticipated theories linking chronic inflammation with the pathogenesis of atherosclerosis and other disorders of the aged.

    2014-01-01

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

    Species richness and seasonal abundance of solitary bees were investigated in rocky, montane grassland (campo rupestre) (1180 m asl) and cerrado sensu stricto (680 m asl) in the Biribiri State Park, Diamantina, state of Minas Gerais, Brazil. Three hundred nineteen nest traps of bamboo canes and black cardboard tubes were monthly inspected at each site during 15 months. A total of eight species of bees built 97 nests. Four species were common to both sites. Tetrapedia aff. curvitarsis Friese and Tetrapedia aff. peckoltii Friese were the most abundant at campo rupestre and cerrado s.s., respectively, followed by Centris analis (Fabricius) in campo rupestre and Centris tarsata Smith in cerrado s.s. The nesting peaks occurred in May in campo rupestre and in February in cerrado s.s. Three cuckoo bees and one bee-fly were collected as natural enemies. The findings suggest that differences between the sites were related more to ecological factors (floral resources, natural nest sites) than to the altitudinal difference. The species richness was similar to that in other habitats with open vegetation. We demonstrate the need to use several types of trap-nest to increase the range of species sampled; some species used only one of the two types traps provided. We also comment on the limitations of trap-nests in cerrado vegetation. Most cerrado species of bees are very selective in their choice for a nesting site, but bees that use trap-nests are more generalists.

    Full Text Available A aceroleira é uma importante frutífera tropical que pode produzir frutos o ano todo na região semiárida do Nordeste do Brasil, caso seja utilizada a irrigação. Como a aceroleira depende da polinização por abelhas coletoras de óleos florais para apresentar uma produção satisfatória de frutos, este trabalho teve como objetivo avaliar a abundância de polinizadores e o sucesso reprodutivo da cultura no período seco, no semiárido paraibano. Foram registradas quatro espécies de abelhas nativas da tribo Centridini, todas consideradas polinizadoras efetivas da aceroleira, pela frequência nas flores e comportamento: Centris aenea Lepeletier, C. tarsata Smith, C. fuscata Lepeletier e C. trigonoides Lepeletier (Apidae, Centridini. A frequência de visitas às flores foi menor no período seco do que no período chuvoso. A polinização cruzada manual complementar resultou em incremento de 61 a 74% na produção de frutos durante o período seco, nos dois anos avaliados, indicando que há um grande déficit de polinização devido à baixa abundância de abelhas Centris. Esse resultado implica a necessidade de manejo dos polinizadores, especialmente em cultivos irrigados durante o período seco, na região semiárida do Nordeste do Brasil.

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

    Full Text Available Quest’articolo parte dallo studio delle città portuali storiche, siti UNESCO, che oggi affrontano la sfida della riqualificazione dei waterfront urbani attraverso la conservazione del patrimonio culturale e paesaggistico. Le raccomandazioni sull’ “Historic Urban Landscape”, e gli strumenti operativi promossi dall’ICOMOS “Guidance on Heritage Impact Assessments for Cultural World Heritage Properties” del 2011, si configurano come le più recenti disposizioni concernenti la conservazione, protezione e valorizzazione del patrimonio culturale (Fusco Girard, 2010. La Guida ICOMOS è stata considerata lo strumento più adatto per valutare gli impatti dei grandi progetti di riqualificazione dei waterfront urbani sul patrimonio culturale. Per comprendere al meglio tale strumento è stata fatta un’applicazione per valutare gli impatti del Grande Progetto Pompei sul waterfront di Torre Annunziata, città costiera nel Golfo di Napoli sito UNESCO. A questa fase di analisi segue una riflessione su come migliorare l’Heritage Impact Assessment, come strumento capace di valutare non soltanto gli impatti culturali ma anche quelli economici, per parlare di “economia del patrimonio culturale”. La proposta ultima è quella di affiancare al processo di “Heritage Impact Assessment” una valutazione degli impatti economici, attraverso un’analisi costi-benefici, per quantificare in termini monetari la convenienza degli investimenti nella conservazione del patrimonio storico urbano delle città costiere, proponendo una “Economic Heritage Impact Assessment” (EHIA. Tale metodo, elaborato dall’autrice all’interno della tesi di dottorato “Il paesaggio storico urbano delle città costiere: sfide e opportunità. Il caso Torre Annunziata”, offre la possibilità di superare la sola valutazione degli impatti culturali proposta dall’ICOMOS.

And 22 scenario of NEI's generic list were evaluated not applicable to SKN3. During the review of the scenario contained in NEI 00-01, no additional MSO scenarios specific to SKN3 were identified. For the further study, the final review will be determined and then detailed circuit analysis will be performed by fire zone and area based on the exact location contained the cable and raceway. With the enhancement of fire safety regulation requirements in nuclear power industry, multiple spurious operation (MSO) identification and treatments should be included in post fire safe shutdown analysis (PFSSA). In this study, the MSO scenario reviews are performed for Shin Kori Unit 3(SKN3) which is the first nuclear power plant of the Advanced Power Reactor 1400 constructed in Korea.

    Genetic variability of eight Colombian field populations and two laboratory colonies of a tropical forest sand fly, Lutzomyia shannoni Dyar, was assessed by comparing allozyme frequencies at 20 enzyme loci. Substantial genetic variability was noted in all strains, with mean heterozygosities of 13-21% and alleles per locus of 2.0-2.8. Four loci were monomorphic. Six populations in north and central Colombia showed close genetic similarity (Nei's distances, 0.01-0.09), despite mountainous environment, discontinuous forest habitat, and elevation differences from 125 to 1,220 m. Two samples representing the Orinoco (near Villavicencio) and Amazon (near Leticia) river basins were similar (Nei's distance, 0.08) but diverged substantially from the central six samples (Nei's distances, 0.26-0.40). Although the range of L. shannoni extends from the southeastern United States to northern Argentina, three genetically distinct, geographically discrete, groups were discerned by the current analysis: Orinoco-Amazon river basins, north-central Colombia, and eastern United States.

    Low energy electron irradiation of lithium fluoride (LiF), in the form of bulk crystals and films, gives rise to the stable formation of primary F defects and aggregated color centers in a thin layer located at the surface of the investigated material. For the first time a confocal light scanning microscope (CLSM) in fluorescence mode was used to reconstruct the depth distribution of efficiently emitting laser active color centers in a stripe-like region induced by 12 and 16 keV electrons on LiF films thermally evaporated on glass. The formation of the F{sub 3}{sup +} and F{sub 2} aggregated defects appears restricted to the electron penetration and proportional to their energy depth profile, as obtained from Monte Carlo simulations. [Italian] L'irraggiamento con elettroni di bassa energia del fluoruro di litio (LiF), in forma di cristalli e film, induce la formazione di difetti primari F e centri di colore aggregati stabili in un sottile strato localizzato alla superficie del materiale investigato. Per la prima volta un microscopio confocale a scansione (CLSM) in modalita' fluorescenza e' stato usato per ricostruire la distribuzione di centri di colore laser attivi ad alta efficienza di emissione nel visibile, in strisce colorate ottenute con elettroni da 12 e 16 keV su film di LiF evaporati termicamente su vetro. La formazione dei difetti aggregati F2 e F3+ risulta ristretta spazialmente nella regione di penetrazione degli elettroni e proporzionale al profilo della distribuzione dell'energia da essi depositata, ricavata tramite simulazioni Monte Carlo.

    In the framework of an ADS study (Accelerator Driven System, a reactor cooled by a lead bismuth alloy) the distribution of the deposited energy between the fuel, coolant and structural materials was evaluated by means of Monte Carlo calculations. The energy deposition in the coolant turned out to be about four percent of the total deposited energy. In order to study this effect, further calculations were performed on water and sodium cooled reactors. Such an analysis showed, for both coolant materials, a much lower heat deposition, about one percent. Based on such results, a thermohydraulic analysis was performed in order to verify the effect of this phenomenon on the fuel assembly temperature distribution. The main effect of a significant fraction of energy deposition in the coolant is concerned with the decrease of the fuel pellet temperature. As a consequence, taking into account this effect allows to increase the possibilities of optimization at the disposal of the designer. [Italian] Nell'ambito dello studio di un ADS (Accelerator Driven System, un reattore refrigerato per mezzo di una lega di piombo-bismuto) per mezzo di calcoli Monte Carlo sono stati valutati i contributi di deposizione di potenza nei materiali fissile, strutturale e refrigerante, ottenendo che il contributo della potenza depositata nel refrigerante e' pari al quattro per cento circa del totale. Allo scopo di meglio approfondire questo effetto, sono stati effettuati ulteriori calcoli in relazione a reattori refrigeranti ad acqua e sodio; i risultati mostrano come, in questi casi, la deposizione di potenza nel refrigerante sia decisamente inferiore dell'ordine di un per cento circa. Sulla base di tali risultati, e' stata avviata un'analisi di caratterre termoidraulico avente lo scopo di verificare l'effetto di questo fenomeno sulla distribuzione di temperatura negli elementi di combustibile.

    Obiettivi: la ricerca dei virus enterici in matrici ambientali, soprattutto nei reflui urbani, risulta di grande interesse sia per la valutazione del rischio di natura virale sia per compiere studi epidemiologici.

    Lo scopo di questo lavoro è stato l’applicazione parallela di diverse tecniche attualmente in uso in virologia clinica a isolati citopatogeni ambientali al fine di ottenere una precisa identificazione degli agenti rilevati.

    Metodi: sono stati analizzati 21 campioni di aerosol, provenienti da impianti di depurazione di reflui civili a fanghi attivi, e risultati citopatogeni in colture di cellule BGM.

    Dopo una nuova semina in “shell vials”, su tre linee cellulari continue per mettere in evidenza eventuali differenze nello spettro di citopatogenicità. Per l’identificazione degli isolati virali, sono state adottate in parallelo: microscopia elettronica, tecniche biomolecolari di amplificazione genica, elettroforesi su gel di poliacrilamide (PAGE, test immunoenzimatici, sieroneutralizzazione.

    Risultati: la semina in “shell vials” ha confermato la
    presenza di particelle virali infettive in tutti i campioni
    tranne uno; inoltre ha permesso di ridurre il
    tempo di comparsa dell’effetto citopatico a 3-4 giorni
    contro i 6-8 giorni necessari seminando in fiasche.
    La microscopia elettronica ha individuato la presenza
    di particelle enterovirus-simili in 18 dei 21
    campioni e di virioni della famiglia Reoviridae in 8.
    La positività dei campioni è stata ottenuta, inoltre,
    con la RT-PCR, per 2 campioni di enterovirus e 2 di
    reovirus e con la PAGE in 6 campioni. Il presente
    studio ha portato ad un’identificazione sufficientemente
    certa di reovirus in 2 campioni e di enterovirus
    in 1 campione.

    Hydroxyl radical (OH) among reactive oxygen species cause damage to nucleobases with thymine being the most susceptible, whilst in contrast, the singlet oxygen ((1)02) targets only guanine bases. The high GC content of mycobacterial genomes predisposes these organisms to oxidative damage of guanine. The exposure of cellular DNA to OH and one-electron oxidants results in the formation of two main degradation products, the pro-mutagenic 8-oxo-7,8-dihydroguanine (8-oxoGua) and the cytotoxic 2,6-diamino-4-hydroxy-5-formamidopyrimidine (FapyGua). These lesions are repaired through the base excision repair (BER) pathway and we previously, demonstrated a combinatorial role for the mycobacterial Endonuclease III (Nth) and the Nei family of DNA glycosylases in mutagenesis. In addition, the formamidopyrimidine (Fpg/MutM) and MutY DNA glycosylases have also been implicated in mutation avoidance and BER in mycobacteria. In this study, we further investigate the combined role of MutY and the Fpg/Nei DNA glycosylases in Mycobacterium smegmatis and demonstrate that deletion of mutY resulted in enhanced sensitivity to oxidative stress, an effect which was not exacerbated in Δfpg1 Δfpg2 or Δnei1 Δnei2 double mutant backgrounds. However, combinatorial loss of the mutY, fpg1 and fpg2 genes resulted in a significant increase in mutation rates suggesting interplay between these enzymes. Consistent with this, there was a significant increase in C → A mutations with a corresponding change in cell morphology of rifampicin resistant mutants in the Δfpg1 Δfpg2 ΔmutY deletion mutant. In contrast, deletion of mutY together with the nei homologues did not result in any growth/survival defects or changes in mutation rates. Taken together these data indicate that the mycobacterial mutY, in combination with the Fpg DNA N-glycosylases, plays an important role in controlling mutagenesis under oxidative stress.

    OBIETTIVI: valutare e quantificare l'esposizione umana al mercurio (Hg) ed esplorare i fattori chiave che influenzano la contaminazione nelle popolazioni residenti in prossimità della Rada di Augusta, un'area a elevato rischio ambientale a causa degli effetti degli sversamenti incontrollati di Hg da parte di uno dei più grandi impianti cloro-soda d'Europa. DISEGNO: un campione di residenti nei comuni di Augusta, Priolo e Melilli (Sicilia orientale) è stato selezionato per lo studio di biomonitoraggio umano. Un questionario dettagliato è stato somministrato a ogni partecipante per raccogliere informazioni anagrafiche sulle abitudini di vita e alimentari. I livelli di Hg in sangue e capelli, usati come traccianti di esposizione a metilmercurio, sono stati messi in relazione al consumo di pesce locale. Il contenuto di Hg nelle urine è stato utilizzato per esplorare eventuali esposizioni atmosferiche a Hg inorganico. Una regressione lineare multivariata è stata applicata con l'obiettivo di esplorare i fattori che influenzano l'esposizione umana al Hg. L'approccio tossicocinetico è stato impiegato al fine di calcolare la dose settimanale provvisoria tollerabile ( provisional tolerable weekly intake, PTWI) e di predire le concentrazioni di Hg attese nel sangue degli individui con una dieta alimentare basata esclusivamente su pesce locale. 224 individui residenti nei comuni di Augusta, Melilli e Priolo. RISULTATI: eccessi di Hg sono stati misurati nel sangue e nei capelli del campione considerato. I più alti livelli sono stati rilevati ad Augusta, dove anche il consumo di pesce locale risulta maggiore. I valori di dose settimanale tollerabile provvisoria (PTWI) calcolati eccedono, nella maggior parte dei casi, le raccomandazioni internazionali, specialmente nei residenti ad Augusta. CONCLUSIONI: gli elevati livelli di Hg registrati nei campioni di sangue e capelli derivano, con ogni probabilità, dal consumo di pesce locale. Rispetto ad Augusta, gli individui di

    Full Text Available L’influenza dei caratteri urbani sulla domanda di mobilità è un tema ampiamente dibattuto e studiato. Al di là delle assunzioni teoriche a riguardo, molti studiosi hanno tentato di individuare empiricamente nessi attestanti questo fenomeno. Gran parte della letteratura scientifica sul tema può essere ricondotta al dibattito sulla città compatta e sullo sprawl. Due principali obiettivi contraddistinguono questo dibattito: la comprensione delle complesse dinamiche che legano la domanda di mobilità ai caratteri urbani e l’individuazione di configurazioni sostenibili degli usi del suolo. Il fenomeno è dunque studiato al fine dello sviluppo di strategie fondate sull’integrazione tra i trasporti e gli usi del suolo, finalizzate a limitare l’uso dell’auto e ad ottenere una distribuzione modale degli spostamenti più equilibrata. Buona parte della ricerca scientifica, specialmente nell’ultimo decennio, è dunque focalizzata sull’identificazione di nessi causali tra gli usi del suolo e i trasporti, per supportare, o in alcuni casi mettere in discussione, esperienze e politiche integrate. Nonostante la quantità e varietà di studi dedicati al tema, il fenomeno è ancora lungi dall’essere compreso e dimostrato empiricamente. Il dibattito in proposito è ampio e l’impressione è che con l’aumentare degli studi in proposito e del livello di approfondimento delle analisi diminuisca la sensazione di chiarezza. Attraverso un’analisi della letteratura, l’articolo mette in evidenza i principali problemi emergenti dal dibattito. Senza negare l’importanza del riconoscimento di nessi causali tra i caratteri degli insediamenti e la domanda di mobilità, opinione di chi scrive è che l’individuazione di questi nessi non debba necessariamente costituire una condizione imprescindibile per la definizione e l’adozione di un approccio integrato.

  20. Un modello italiano per l’economia nel Brasile di Getúlio Vargas: la «Carta del Lavoro» del 1927

    Full Text Available Il corporativismo fu uno degli elementi caratterizzanti dello Stato fascista, che con esso intendeva ricollegarsi alla tradizione medievale italiana. Oscillando tra storia e «invented tradition», con esso il governo fascista proponeva una soluzione alla crisi economica degli anni Trenta e un’alternativa allo Stato tanto liberale quanto comunista, cioè una «terza via». Del corporativismo italiano vengono sinteticamente esaminate le origini, l’evoluzione e la struttura, dedicando particolare attenzione alla Carta del Carnaro del 1920, il documento che lo preparò durante l’avventura di Fiume di Gabriele d’Annunzio. Il corporativismo, come modello di gestione economica che negava la lotta di classe, si diffuse in Europa e fuori di essa nell’epoca delle dittature. L’attenzione si concentra sul Brasile, nella sua transizione dalla República Velha alla dittatura di Getúlio Vargas, iniziata nel 1930 e durata fino al 1954, anche se in modo istituzionalmente non unitario. All’interno del movimento che l’accompagnò, l’«Integralismo», il filosofo Miguel Reale (1910–2006 propugnò un corporativismo democratico. Il modello corporativo italiano si riflette in alcune parti della vasta «Consolidação das Leis do Trabalho», emanata da Vargas nel 1943. Essa costituisce un chiaro esempio della legislazione sociale che accompagnò molte dittature del XX secolo e che, nel caso del Brasile, ebbe effetti anche dopo la caduta del regime. La «Consolidação» riguardava però soltanto i lavoratori urbani, mentre il Brasile era una società prevalentemente agraria. Per questo vengono passare in rassegna le misure a favore dei diritti sociali dei lavoratori urbani e agrari prese dai governi di Juscelino Kubitschek (1902–1976 e di João Goulart (1919–1976, nonché, infine, la tutela accordata nel 1964 ai lavoratori agrari dallo Statuto della Terra.

    Full Text Available In Naven, studio classico dell’antropologia culturale e psichiatrica,Gregory Bateson (1936 propone di indicare con ethos “l’espressione di un sistema culturalmente standardizzato di organizzazione degli istinti e delle emozioni degli individui”. Prima di utilizzare il concetto così definito nell’interpretazione della società iatmul della Nuova Guinea, cui ha dedicato una ricerca etnografica, egli propone un sorprendente giro attraverso la cerchia degli intellettuali britannici al fine di mostrare l’estensione del concetto, di presentarlo in un contesto che sia familiare ai suoi lettori e, infine, di respingere preventivamente ogni prospettiva esotizzante. Nei comportamenti di questa élite, possibile reperire, spiega Bateson, dei codici che regolano ciò che, di contro, appare come perfettamente naturale: un certo modo di parlare, di fare dello spirito, di soppesare come ci si debba comportare o discutere. Questo “insieme definito di sentimenti nei confronti del resto del mondo” e questo “atteggiamento definito nei confronti della realtà” sono caratteristici di questo gruppo e ne “determinano i comportamenti”.

    To determine the test-retest repeatability of the National Eye Institute 25-item Visual Function Questionnaire (NEI VFQ-25) for use with older Vietnamese adults with bilateral cataract. The questionnaire was translated into Vietnamese and back-translated into English by two independent translators. Patients with bilateral cataract aged 50 and older completed the questionnaire on two separate occasions, one to two weeks after first administration of the questionnaire. Test-retest repeatability was assessed using the Cronbach's α and intraclass correlation coefficients. The average age of participants was 67 ± 8 years and most participants were female (73%). Internal consistency was acceptable with the α coefficient above 0.7 for all subscales and intraclass correlation coefficients were 0.6 or greater in all subscales. The Vietnamese NEI VFQ-25 is reliable for use in studies assessing vision-related quality of life in older adults with bilateral cataract in Vietnam. We propose some modifications to the NEI-VFQ questions to reflect activities of older people in Vietnam. © 2013 ACOTA.

    Full Text Available The essay deals with some aspects of the knotty question concerning the presence of Aion, Eros and Hades in the variegated universe of the Chaldean Oracles, traditionally attributed to a collaboration between two “Hellenized Magi” of the second c. AD: Julian “the Chaldean” and his son Julian “the Theurgist” (even if the theurgical expertise of the elder Julian, the repository of a more ancient Chaldean tradition, might not involve a direct eastern origin but only his knowledge of “Chaldean” sciences such as astrology and divination”. Aion, who is examined here in terms of his relationship with Chronos, as a more or less autonomous divinity, is mentioned only in the context of some fragments, but his name never appears in the oracular verses. Eros (beloging also to the triad of fr. 46, along with “Faith” and “Truth” stands for an independent cosmological principle whose task is to preserve the universe and the armony of the cosmos. The Chaldean Oracles never make any explicit mention of Hades, who anyway is cited by the Byzantine scholar Psellos as an autonomous divinity of the Chaldeans.

    Objective: To investigate the value of magnetic resonance (MR) perfusion weighted imaging (PWI) in evaluating the blood perfusion of tumor by analyzing the features and indexes of PWI on rabbit VX2 hepatic implantation tumor and normal liver tissue. Methods: Twenty-four New Zealand White rabbits with VX2 carcinoma were established under direct surgical vision embedding tumor tissue. MR examination was performed at 21 days after the tumor implantation. The signal intensity -time curve of hepatic tumor and normal liver tissue were obtained. Mean time to enhance (MTE), negative enhancement integral (NEI), time to minimum (TM), maximum slope of decrease (MSD) and maximum slope of increase (MSI) were measured. Results: MTE, NEI, TM, MSD, and MSI of the normal liver tissue were 208.341±2.226 ms, 78.334±8.152, 24.059±1.927 ms, 38.221±2.443, and 15.389±2.526, respectively. MTE, NEI, TM, MSD, and MSI of the tumor tissue were 175.437±4.182 ms, 123.203±19.455, 17.061±1.834 ms, 125.740±4.842, and 67.832±2.882, respectively. The MTE and TM of tumor were shorter than those of normal hepatic tissue (P<0.05). NEI, MSD, and MSI of tumor were higher than those of normal hepatic tissue (P<0.05). Conclusion: PWI can distinguish the normal liver tissue from the tumor tissue, which is helpful in evaluating blood perfusion of different hepatic tissues. (authors)

    Full Text Available Thanks to the scientist Paul Ekman we are now able to assess the type of influence that our non-verbal behaviour has on other people: we can now judge the ability of people to send non-verbal signals and know how to interpret them. We recognize that information provided by words in some cases is contradicted and refuted by the non-verbal expressions that accompany it, and that, when one cannot use words, information can be communicated through non-verbal signs. The emotions are states of mind associated with physiological and psychophysiological changes, with internal or external stimuli, or with natural or learned behaviour. They are associated with mood, temperament, personality and disposition, and motivation. In most cases, lies can be detected because of signs of hidden emotions; the more intense and varied the emotions are, the more likely it is that a lie is unintentionally betrayed. The facial expressions and body language can reveal deep emotions: the presence of a specific emotional state is indicated by a shaky voice, an alteration of tone, a sunny smile, or a furrowed brow. Unlike ordinary expressions and gestures, it is difficult to hide micro-expressions and micro-gestures. Micro-expressions express the seven universal emotions: disgust, anger, fear, sadness, happiness, surprise, and contempt. In 1990 Paul Ekman expanded this list of basic emotions, including a range of positive and negative emotions, not all encoded in facial muscles. These emotions are amusement, contempt, embarrassment, excitement, guilt, pride, relief, satisfaction, pleasure, and shame. Micro-gestures are hard to conceal too, because every little movement is like a word that has a different meaning according to the use made of it in a ‘sentence’. Therefore, in order to analyze a gesture correctly one should keep in mind the context in which it is expressed.

    Full Text Available A trial was conducted to: i evaluate the BW growth, energy intakes and energetic efficiency of pigs fed high and low density diets from 27 to 141 kg BW, ii evaluate sire line and sex differences when fed both diets, and iii to compare ME to NE as predictor of pig performance. The experiment had a replicated factorial arrangement of treatments including four sire lines, two sexes (2,192 barrows and 2,280 gilts, two dietary energy densities and a light or heavy target BW, 118 and 131.5 kg in replicates 1 to 6 and 127 and 140.6 kg in replicates 7 to 10. Pigs were allocated to a series of low energy (LE, 3.27 Mcal ME/kg corn-soybean meal based diets with 16% wheat midds or high energy diets (HE, 3.53 to 3.55 Mcal ME/kg with 4.5 to 4.95% choice white grease. All diets contained 6% DDGS. The HE and LE diets of each of the four phases were formulated to have equal lysine:Mcal ME ratios. Pigs were weighed and pen feed intake (11 or 12 pigs/pen recorded at 28-d intervals. The barrow and gilt daily feed (DFI, ME (MEI and NE (NEI intake data were fitted to a Bridges function of BW. The BW data of each sex were fitted to a generalized Michaelis-Menten function of days of age. ME and NE required for maintenance (Mcal/d were predicted using functions of BW (0.255 and 0.179 BW^0.60 respectively. Pigs fed LE diets had decreased ADG (915 vs. 945 g/d, p<0.001 than pigs fed HE diets. Overall, DFI was greater (p<0.001 for pigs fed the LE diets (2.62 vs. 2.45 kg/d. However, no diet differences were observed for MEI (8.76 vs. 8.78 Mcal/d, p = 0.49 or NEI (6.39 vs. 6.44 Mcal/d, p = 0.13, thereby indicating that the pigs compensated for the decreased energy content of the diet. Overall ADG:DFI (0.362 vs. 0.377 and ADG:Mcal MEI (0.109 vs. 0.113 was less (p<0.001 for pigs fed LE compared to HE diets.

    The objective of this study was to evaluate the effect of integrating dairy and bioenergy systems on land use, net energy intensity (NEI), and greenhouse gas (GHG) emissions. A reference dairy farm system representative of Wisconsin was compared with a system that produces dairy and bioenergy products. This integrated system investigates the effects at the farm level when the cow diet and manure management practices are varied. The diets evaluated were supplemented with varying amounts of dry distillers grains with solubles and soybean meal and were balanced with different types of forages. The manure-management scenarios included manure land application, which is the most common manure disposal method in Wisconsin, and manure anaerobic digestion (AD) to produce biogas. A partial life cycle assessment from cradle to farm gate was conducted, where the system boundaries were expanded to include the production of biofuels in the analysis and the environmental burdens between milk and bioenergy products were partitioned by system expansion. Milk was considered the primary product and the functional unit, with ethanol, biodiesel, and biogas considered co-products. The production of the co-products was scaled according to milk production to meet the dietary requirements of each selected dairy ration. Results indicated that land use was 1.6 m2, NEI was 3.86 MJ, and GHG emissions were 1.02 kg of CO2-equivalents per kilogram of fat- and protein-corrected milk (FPCM) for the reference system. Within the integrated dairy and bioenergy system, diet scenarios that maximize dry distillers grains with solubles and implement AD had the largest reduction of GHG emissions and NEI, but the greatest increase in land use compared with the reference system. Average land use ranged from 1.68 to 2.01 m2/kg of FPCM; NEI ranged from -5.62 to -0.73 MJ/kg of FPCM; and GHG emissions ranged from 0.63 to 0.77 kg of CO2-equivalents/kg of FPCM. The AD contributed 65% of the NEI and 77% of the GHG

    Highlights: • We studied the combined role of MutY and Fpg DNA glycosylases in M. smegmatis. • Loss of MutY showed increased sensitivity to oxidative damage. • Loss of MutY together with the Fpg glycosylases showed increased mutation rates. • Our data indicate interplay between these enzymes to control mutagenesis. - Abstract: Hydroxyl radical (·OH) among reactive oxygen species cause damage to nucleobases with thymine being the most susceptible, whilst in contrast, the singlet oxygen ( 1 0 2 ) targets only guanine bases. The high GC content of mycobacterial genomes predisposes these organisms to oxidative damage of guanine. The exposure of cellular DNA to ·OH and one-electron oxidants results in the formation of two main degradation products, the pro-mutagenic 8-oxo-7,8-dihydroguanine (8-oxoGua) and the cytotoxic 2,6-diamino-4-hydroxy-5-formamidopyrimidine (FapyGua). These lesions are repaired through the base excision repair (BER) pathway and we previously, demonstrated a combinatorial role for the mycobacterial Endonuclease III (Nth) and the Nei family of DNA glycosylases in mutagenesis. In addition, the formamidopyrimidine (Fpg/MutM) and MutY DNA glycosylases have also been implicated in mutation avoidance and BER in mycobacteria. In this study, we further investigate the combined role of MutY and the Fpg/Nei DNA glycosylases in Mycobacterium smegmatis and demonstrate that deletion of mutY resulted in enhanced sensitivity to oxidative stress, an effect which was not exacerbated in Δfpg1 Δfpg2 or Δnei1 Δnei2 double mutant backgrounds. However, combinatorial loss of the mutY, fpg1 and fpg2 genes resulted in a significant increase in mutation rates suggesting interplay between these enzymes. Consistent with this, there was a significant increase in C → A mutations with a corresponding change in cell morphology of rifampicin resistant mutants in the Δfpg1 Δfpg2 ΔmutY deletion mutant. In contrast, deletion of mutY together with the nei homologues

    Human albinism is a genetic condition associated with visual impairment that affects many aspects of daily life. Office measurements of visual acuity do not necessarily reflect daily visual function and health status. This study used the National Eye Institute Visual Function Questionnaire (NEI-VFQ) to determine the effect of albinism-associated ophthalmopathy on quality of life (QOL). We administered the NEI-VFQ, which consists of 25 questions about QOL (VFQ-25) and 14 questions about well-being (VFQ-39), to 44 consenting participants with albinism older than the age of 18 years. Nineteen male and 25 female subjects completed the study. Median age was 30.5 years (range, 18-79 years). Mean best-corrected visual acuity was 20/83 (range, 20/20 to 20/320). Forty-eight percent reported that they were currently able to drive with their condition. Participants perceived midscale problems with their general vision (median subscale score 60.0). Visual acuity correlated moderately with overall NEI-VFQ composite scores (r(s) = 0.40, p = 0.01 for VFQ-25 and r(s) = 0.36, p = 0.02 for VFQ-39). Most notable impairment was recorded for distance acuity, vision-specific mental health, and vision-specific role difficulties (VFQ-39 median subscale scores 66.7, 70.0, and 75.0, respectively). Differences by sex were insignificant. Greater ceiling effects were noted for the VFQ-25 than for the VFQ-39. The NEI-VFQ-39 is a method to evaluate self-reported effects of vision-related QOL in albinism and may be used as a baseline for evaluating outcomes in interventional studies in these patients.

    Cataracts are the leading cause of blindness worldwide and cause visual impairment for millions of adults in the United States. We compared the sensitivity of a vision-specific health-related quality of life (HRQOL) measure to that of multiple generic measures of HRQOL before and at 2 time points after cataract surgery. Participants completed 1 vision-specific and 5 generic quality of life measures before cataract surgery, and again 1 and 6 months after surgery. Random effects modeling was used to measure changes over the three assessment points. The NEI-VFQ25 total score and all 11 subscales showed significant improvements during the first interval (baseline and 1 month). During the second interval (1-6 months post-surgery), significant improvements were observed on the total score and 5 of 11 NEI-VFQ25 subscales. There were significant increases in HRQOL during the first interval on some preference-based generic HRQOL measures, though changes during the second interval were mostly non-significant. None of the SF-36v2™ or SF6D scales changed significantly between any of the assessment periods. The NEI-VFQ25 was sensitive to changes in vision-specific domains of QOL. Some preference-based generic HRQOL measures were also sensitive to change and showed convergence with the NEI-VFQ25, but the effects were small. The SF-36v2™ and SF-6D did not change in a similar manner, possibly reflecting a lack of vision-related content. Studies seeking to document both the vision-specific and generic HRQOL improvements of cataract surgery should consider these results when selecting measures.

    Recent increases in the Natural Gas (NG) production through hydraulic fracturing have questioned the climate benefit of switching from coal-fired to natural gas-fired power plants. Higher than expected levels of methane, VOCs, and NOx have been observed in areas close to oil and NG (OnG) operation facilities. High uncertainty in the OnG emission inventories and methane budget challenge the assessment of OnG impact on air quality and climate and consequently development of effective mitigation policies and control regulations. In this work, we focus on reducing the uncertainties around the OnG emissions by using high resolution (4x4 km2) WRF-Chem simulations coupled with detailed observation from the Front Range Air Pollution and Photochemistry Éxperiment (FRAPPÉ 2014) field campaign. First, we identified the optimal WRF-Chem configurations in the NFR area. We compared the performance of local and non-local Planetary Boundary Layer (PBL) schemes in predicting the PBL height and vertical mixing in the domain. We evaluated the impact of different meteorological and chemical initial and boundary conditions on the model performance. Next, simulations based on optimal configurations were used to assess the performance of the emission inventory (NEI-2011v2). To evaluate the impact of OnG emission on regional air quality and performance of NEI-2011 we tested the sensitivity of the model to the OnG emission. Comparison between simulated values and ground-based and airborne measurements shows a low bias of OnG emission in NEI-2011. Finally, inverse modeling techniques based on emission sensitivity simulations are being used to optimal scaling the OnG emission from the NEI-2011.

    Age-related macular degeneration (AMD) is a leading cause of blindness over the age of 50 in western countries. People with AMD are suffering from serious vision-related disability and their social life is compromised. The aim of our study was to assess quality of life (QoL) in patients with exudative AMD. The study group was 100 patients treated for AMD, the control group were 30 age and sex matched subjects without ophthalmic disorders. Patients were treated with anti-VEGF therapy, by means of National Eye Institute Visual Function Questionnaire (NEI VFQ-25). As well as visual function, the NEI-VFQ investigates social functioning, mental health and dependency. There was statistically significant difference in QoL overall score between study group and control group. Patients with AMD obtained 51.1 (+/- 20.5 ) overall score, control group reached 83.7 (+/- 11.7) overall score, p = 0.001. Detailed analysis of study group revealed low acceptance of the disease and strong dependency. QoL in patients with AMD assessed with NEI VFQ-25, is significantly impaired. Low quality of life and difficulties in performing daily activities point at the need of formal psychological and social care.

    Current IST requirements were developed mainly through deterministic-based methods. While this approach has resulted in an adequate level of safety and reliability for pumps and valves, insights from probabilistic safety assessments suggest a better safety focus can be achieved at lower costs. That is, some high safety impact pumps and valves are currently not tested under the IST program and should be added, while low safety impact valves could be tested at significantly greater intervals than allowed by the current IST program. The nuclear utility industry, through the Nuclear Energy Institute (NEI), has developed a draft guideline for applying risk-based techniques to focus testing on those pumps and valves with a high safety impact while reducing test frequencies on low safety impact pumps and valves. The guideline is being validated through an industry pilot application program that is being reviewed by the U.S. Nuclear Regulatory Commission. NEI and the ASME maintain a dialogue on the two groups` activities related to risk-based IST. The presenter will provide an overview of the NEI guideline, discuss the methodological approach for applying risk-based technology to IST and provide the status of the industry pilot plant effort.

    The Materials, Processes, and Environmental Engineering Network (MPEEN) was developed as a central holding facility for materials testing information generated by the Materials and Processes Laboratory. It contains information from other NASA centers and outside agencies, and also includes the NASA Environmental Information System (NEIS) and Failure Analysis Information System (FAIS) data. Environmental replacement materials information is a newly developed focus of MPEEN. This database is the NASA Environmental Information System, NEIS, which is accessible through MPEEN. Environmental concerns are addressed regarding materials identified by the NASA Operational Environment Team, NOET, to be hazardous to the environment. An environmental replacement technology database is contained within NEIS. Environmental concerns about materials are identified by NOET, and control or replacement strategies are formed. This database also contains the usage and performance characteristics of these hazardous materials. In addition to addressing environmental concerns, MPEEN contains one of the largest materials databases in the world. Over 600 users access this network on a daily basis. There is information available on failure analysis, metals and nonmetals testing, materials properties, standard and commercial parts, foreign alloy cross-reference, Long Duration Exposure Facility (LDEF) data, and Materials and Processes Selection List data.

    Metastable rare gas atoms play an important role in all types of plasmas and gas discharges, e.g. in fluorescent lamps and in laser discharges (helium-neon laser or excimer lasers). In this thesis, the metastable states of NeI are studied. First, the theory of excited neon atoms and diatomic molecules is introduced, as well as Penning ionisation. Next, some experimental facilities are described (e.g. the dye laser system). With these instruments, natural lifetime measurements of the 2p fine structure states of NeI are carried out. Results are reported. Finally, total Penning ionisation cross sections are calculated using the optical potential model. (Auth.)

    In 2000, the Nuclear Energy Institute (NEI), nuclear utilities, and the U.S. Nuclear Regulatory Commission (NRC) embarked on a series of working meetings designed to develop means to assess the post-accident performance of control room ventilation systems to ensure required control room habitability (CRH). Through monthly meeting interactions beginning in January 2000, teams from the industry and the NRC have been working to develop an industry approach for assessment of existing systems. New system evaluation techniques are being developed that will allow for evaluation and/or identification of potential performance improvement options. NRC review of the documentation of this approach, as well as broad industry comment, was performed in the first part of 2001. This session will examine technical development topics covering licensing, analysis, testing, and control room refurbishment. NRC, NEI, utility, vendor, and consultant presentations will be followed by a panel session that will explore both process and technical recommendations for improvements. Since the mid-1980's, the NRC has communicated concerns on the inadequacies of control room designs relating to CRH requirements. In the mid-1990's, testing of some control room envelopes indicated that key assumptions supporting the radiological dose analysis might be incorrect. In 1998, the NRC held a public workshop to address CRH concerns. In late 1999, the NRC and the industry agreed to work together on issues affecting CRH and develop the NEI 99-03 guidance document for resolving those issues. This NEI 99-03 industry document defines a process for licensees to assess a plant's design and licensing bases for CRH to ensure that they are established and maintained throughout the life of the plant. The assessment process describes a comparative approach to determine if the plant configuration and operation are consistent with the CRH licensing basis and analysis. The process includes evaluation, testing, and

    During the period November 1994 - May 1995 the coordinating group of WBC centres working in Italy organised the 2. national intercalibration and intercomparison campaign. A BOMAB phantom was used filled with four radionuclides gel solution with gamma energy emissions ranging between 100 keV and 2 MeV. 17 out of 21 Italian WBC centres took part in the campaign. Through the intercalibration, organised according to internationally accepted methodologies, each WBC centre could check its own calibration procedures. many intermediate data, collected for the methodologies and measurement procedures intercomparison, permitted analyses and comparison of uncertainly causes in a WBC measurement of the internal contamination. A proposal of MDA definition and assessment procedure resulted from the intercomparison campaign. [Italiano] Il Coordinamento dei Centri WBC operanti in Italia ha organizzato la seconda campagna di intercalibrazione ed interconfronto nazionale basata sulle misure di un fantoccio BOMAB riempito con una soluzione radioattiva gelificata contenente 4 radionuclidi con emissioni gamma nell`intervallo energetico compreso fra 100 keV e 2 MeV. Alla campagna, che si e` svolta fra novembre 1994 e maggio 1995, hanno partecipato 17 dei 21 Centri WBC censiti in Italia. L`intercalibrazione e` stata organizzata secondo criteri ormai consolidati in campo internazionale ed ha permesso ad ognuno dei partecipanti di verificare le proprie procedure di calibrazione. Per l`interconfronto delle procedure e dei metodi di misura impiegati e` stata raccolta una serie di dati intermedi che hanno consentito di analizzare e confrontare le fonti di incertezza insite nella misura di contaminazione interna nell`uomo tramite WBC. Cio` ha infine reso possibile una proposta di definizione e di procedura di determinazione del valore della minima attivita` rivelabile (MDA) in accordo con le piu` recenti tendenze in campo internazionale.

    Le encefalopatie spongiformi trasmissibili (EST sono malattie del sistema nervoso dell’uomo, ad esito infausto. L’agente eziologico, la proteina prionica (PrP, può trasformarsi e accumularsi nella cellula nervosa causandone la morte. La scoperta negli anni ‘90 di una variante (v. Cruetzfieldt Jakob Disease, correlata all’encefalopatia spongiforme bovina, che colpisce soggetti sotto i 30 anni, ha aumentato l’interesse per le EST.

    I paesi della comunità europea hanno adottano misure di controllo della carne bovina e si sono dotati di osservatori epidemiologici. Pertanto anche in Italia si è avuta l’esigenza di doverne disporre. Si è deciso quindi di istituire anche in Piemonte un centro per la sorveglianza e la notifica delle EST tramite sorveglianza epidemiologica e diagnosi, per mezzo di indagini molecolari e neuropatologiche con la successiva costituzione di una banca dati condivisa con altri centri di riferimento regionali, per la raccolta di dati clinici e strumentali dai reparti di neurologia piemontesi con ricovero in sede dei casi di EST giunti all’osservazione.

    In sede vengono effettuati anche il prelievo, la raccolta, la conservazione di tessuti e altri materiali biologici e si svolgono successive indagini neurobiologiche quali:

     1 la ricerca della proteina 14 3 3 su liquor;

     2 determinazione genotipo del codone 129;

     3 determinazione della sequenza del gene della PrP,

     4 ricerca della PrP proteasi resistente a livello tissutale;

     5 determinazione del sottotipo di PrP. Le indagini neuropatologiche vengono effettuate in collaborazione con dipartimento di Neuroscienze dell’Università di Torino. Si intende inoltre fare promozione attiva delle attività e condivisione delle informazioni raccolte con altri centri.

    To determine if cataract surgery on eyes with AMD confers as much functional visual improvement as surgery on eyes without retinal pathology. This is a retrospective analysis of 4924 cataract surgeries from the Veterans Healthcare Administration Ophthalmic Surgical Outcomes Data Project (OSOD). We included cases of eyes with AMD that had both preoperative and postoperative NEI-VFQ-25 questionnaires submitted and compared their outcomes with controls without retinal pathology. We excluded patients with other retinal pathologies (740 patients). The analyses compared changes in visual acuity and overall functional visual improvement and its subscales using t-tests, multivariate logistic regressions, and linear regression modeling. Preoperative and postoperative questionnaires were submitted by 58.3% of AMD and 63.8% of no retinal pathology cases (controls). Analysis of overall score showed that cataract surgery on eyes with AMD led to increased visual function (13.8 ± 2.4 NEI-VFQ units, P < 0.0001); however, increases were significantly less when compared with controls (-6.4 ± 2.9 NEI-VFQ units, P < 0.0001). Preoperative best-corrected visual acuity (preBCVA) in AMD was predictive of postoperative visual function (r = -0.38, P < 0.0001). In controls, postoperative visual function was only weakly associated with preBCVA (r = -0.075, P = 0.0002). Patients with AMD with vision of 20/40 or better had overall outcomes similar to controls (-2.2 ± 4.7 NEI-VFQ units, P = 0.37). Cataract surgery on eyes with AMD offers an increase in functional visual improvement; however, the amount of benefit is associated with the eye's preBCVA. For eyes with preBCVA of 20/40 or greater, the improvement is similar to that of patients without retinal pathology. However, if preBCVA is less than 20/40, the amount of improvement was shown to be significantly less and decreased with decreasing preBCVA.

  1. COMBINED EFFECTS OF GALAXY INTERACTIONS AND LARGE-SCALE ENVIRONMENT ON GALAXY PROPERTIES

    International Nuclear Information System (INIS)

    Park, Changbom; Choi, Yun-Young

    2009-01-01

    We inspect the coupled dependence of physical parameters of the Sloan Digital Sky Survey galaxies on the small-scale (distance to and morphology of the nearest neighbor galaxy) and the large-scale (background density smoothed over 20 nearby galaxies) environments. The impacts of interaction on galaxy properties are detected at least out to the neighbor separation corresponding to the virial radius of galaxies, which is typically between 200 and 400 h -1 kpc for the galaxies in our sample. To detect these long-range interaction effects, it is crucial to divide galaxy interactions into four cases dividing the morphology of target and neighbor galaxies into early and late types. We show that there are two characteristic neighbor-separation scales where the galaxy interactions cause abrupt changes in the properties of galaxies. The first scale is the virial radius of the nearest neighbor galaxy r vir,nei . Many physical parameters start to deviate from those of extremely isolated galaxies at the projected neighbor separation r p of about r vir,nei . The second scale is at r p ∼ 0.05r vir,nei = 10-20 h -1 kpc, and is the scale at which the galaxies in pairs start to merge. We find that late-type neighbors enhance the star formation activity of galaxies while early-type neighbors reduce it, and that these effects occur within r vir,nei . The hot halo gas and cold disk gas must be participating in the interactions at separations less than the virial radius of the galaxy plus dark halo system. Our results also show that the role of the large-scale density in determining galaxy properties is minimal once luminosity and morphology are fixed. We propose that the weak residual dependence of galaxy properties on the large-scale density is due to the dependence of the halo gas property on the large-scale density.

  2. Technical and regulatory challenges for digital instrumentation and control and control room systems in nuclear plants

    There are several unsettled technical and licensing issues in the areas of instrumentation and control (I and C), human factors, and updated control room designs that need coordinated, proactive industry attention. Some of these issues are already causing protracted regulatory reviews for existing plants, and left untreated, may cause substantial delays and increased costs for new plant combined construction and operating license approvals. Both industry and the NRC will have roles in resolving the key issues and addressing them in future design efforts and regulatory reviews. Where action is needed, the industry will want to minimize costs and risks by defining industry consensus solutions with corresponding technical bases. NEI has formed a working group to coordinate industry efforts and communications with NRC staff. The working group will also help determine priorities and coordinate both new and existing plant resources. EPRI will provide technical input and guidance for the working group. In order to be able to conduct reviews in a timely fashion, the NRC will likely need to enhance and expand staff resources as existing plants are upgraded and new plant reviews become more active. The industry initiative began with a workshop sponsored by EPRI and NEI on March 28-29, 2006, which led to the creation of the NEI working group. The working group has now identified and prioritized important generic issues, established resolution paths and schedules, and identified the roles of various stakeholders including utility companies, EPRI, NEI, vendors and the NRC. Through the course of this initiative I and C issues for both existing and new plants are being addressed. This paper describes the key I and C related technical and regulatory issues and their implications for new and operating plants, and provides a status report on the efforts to resolve them.

    The cantare, a genre which is difficult to define, spreads along a two centuries space of time (between the XIVth and the XVIth century and can be identified with a corpus of greatly varied texts. A broad series of performativity  traces and clues, able to give further evidence of the real recitative essence of the texts, will be anlysed, aiming to ivestigate the question on the performative tradition of the cantari and on the complex alternation between orality and writing, easily detectable in many canterini texts. In this study we will investigate all these components both from their outer and more explicit appearance, with all its formulas and recurrent themes, and through the anlysis of rhetorical and formal constructions, such as: the peculiar structure of the octave, the paratactic construction, references and repetitions, identical, desinantial and cobbled together rhymes, anisosyllabism, a common and general use of correspondence between metre and syntax, minimizing the cases of enjambement. The filing of some texts from the tradition, searching for traces of orality, identified earlier, and the comparison among the respective files, urges to a closer examination of the genre and the texts.

  8. Cibo e scrittura nei romanzi di Stefano Benni

    2015-07-01

     In his nearly forty-year-career, Stefano Benni published a large number of works, each of which is deeply different from one another: all of them are hardly analyzable for their complexity not so much from a quality as from a quantity point of view, because his whole framework is based on the rhetorical device of adiectio. Therefore, it is very useful to analyze the author's works with an intertextual perspective, whose peak is represented by the food theme. Starting from this assumption, it is possible to undertake a textual analysis of his novels, both focused on stylistic features and organized according to a functional standpoint which allows to understand the different uses of the food in the author’s novels: a hint for the author’s imagination, a social pointer, a metaphor, a frame to the characters’ qualities.

    Full Text Available Urban transport plan according to the Italian national Law n.340/ 2000 have the specific aim of improving the traffic situation in the cities. Mobility plans consider all modes of transport planned towards a sustainable urban development. The measures implemented are a mixture of material and immaterial interventions with the aim to reach a better traffic environment with reduced traffic volumes and emissions, increased accessibility and safety and an increased quality of life for all citizens. In Italy, according to the principle that the mobility strategies cannot be separated from the land use planning, many cities are developing innovative Mobility Plans that are integrated with urban planning actions. In order to underline these best practices, a comparative study is proposed between five different urban areas in the central and northern Italy. Most innovative plans have within their strategies the following points: – Promote integrated policies to deal with the complexity of urban transport systems, governance issues and the necessary coherence between different policies, for example between urban mobility and cohesion policy, environment policy or health policy. – Help to green urban transport by introducing new, clean vehicle technologies and alternative fuels and promoting smart charging to encourage transport users to change travel behavior. – Support sharing experience and knowledge to enable better access to this information and help stakeholders to capitalize on these experiences and on relevant data and statistics. – Optimize urban mobility to encourage effective integration, interoperability and interconnection between different transport networks. – Improve road safety to achieve a high level of road safety, especially for vulnerable road users such as young people and the elderly. However only some plans have specific actions towards a real urbanmobility integration. For example the Perugia Mobility Plan define the “urban and mobility planning areas” where the land use changes and the new transport infrastructures are planned and implemented at the same time. The Bolzano Mobility Plan defines specific actions for the open spaces and pedestrian networks, that are considered as an integrated part of the multi-modal transport system. Another example is the Reggio Emilia Mobility Plan, that defines specific actions for the Transit Oriented Development of the metropolitan area. These innovative plans are the first examples of a new approach for the integrated transport and land use planning and represent the first step towards an effective integration towards new mobility patterns in cities and sustainable development of urban areas.

    20 lactating ewes were allotted to two groups: 10 subjects received orally 100 mg/day of CdCl{sub 2} for 108 consecutive days, and the remaining 10 acted as control. Reproductive performance in ewes and cadmium tissue accumulation, both in ewes and their lambs, were investigated. The results showed that in ewes: 1) the regular cadmium intestinal intake negatively influences all reproductive parameters; 2) cadmium is particularly accumulated in kidney and liver, bur also in mammary gland, although at distinctly lower level; 3) chronic administration does not increase cadmium placental transfer in lactating pregnant subjects. [Italian] 20 pecore in lattazione sono state suddivise in 2 gruppi: 10 soggetti ricevettero per os 100 mg/giorno di CdCl{sub 2} per 108 giorni consecutivi, e i restanti 10 funsero da controllo. Sono stati studiati i parametri riproduttivi delle pecore e l'accumulo di cadmio nei tessuti, sia delle pecore che dei loro agnelli. I risultati hanno mostrato che negli ovini: 1) il regolare assorbimento intestinale di cadmio influenza negativamente tutti i parametri riproduttivi; 2) il cadmio viene accumulato principalmente nei reni e nel fegato, ma anche dalla ghiandola mammaria, sebbene in misura nettamente inferiore; 3) la somministrazione cronica di cadmio nei soggetti gravidi non incrementa il suo passaggio transplacentare.

    The banana weevil (BW), Cosmopolites sordidus (Coleoptera: Curculionidae), is one of the most important insect pests of bananas and plantains. The mobility and the origin of BW infestations at the Canary Islands (Tenerife, La Gomera and La Palma) have been analysed using Random Amplified Polymorphic DNA (RAPD) as molecular markers. Populations from Costa Rica, Colombia, Uganda and Madeira were also included for comparison. One hundred and fifteen reproducible bands from eight primers were obtained. The level of polymorphism in the populations from the Canary Islands (40-62%) was in the range of those found in other populations. Nei's genetic distances, pair-wise fixation index (FST) values indicate that the closest populations are Tenerife populations among themselves (Nei's genetic distance=0.054-0.100; FST=0.091-0.157) and Costa Rica and Colombia populations (Nei's genetic distance=0.049; FST=0.113). Our results indicate the existence of BW local biotypes with limited gene flow and affected by genetic drift. These results are compatible with a unique event of colonization at Tenerife; whereas, the outbreaks in La Gomera and La Palma may come from independent introductions. The Madeira population is phylogenetically and geographically closer to the Canary Islands populations, suggesting that it is the most likely source of the insects introduced in the Canary Islands.

    Sequence-related amplified polymorphism (SRAP) molecular markers were used to detect the genetic diversity of 32 wild accessions of Cynodon dactylon collected from Sichuan, Chongqing, Guizhou and Tibet, China. The following results were obtained. (1) Fourteen primer pairs produced 132 polymorphic bands, averaged 9.4 bands per primer pair. The percentage of polymorphic bands in average was 79.8%. The Nei's genetic similarity coefficient of the tested accessions ranged from 0.591 to 0.957, and the average Nei's coefficient was 0.759. These results suggested that there was rich genetic diversity among the wild resources of Cynodon dactylon tested. (2) Thirty two wild accessions were clustered into four groups. Moreover, the accessions from the same origin frequently clustered into one group. The findings implied that a correlation among the wild resources, geographical and ecological environment. (3) Genetic differentiation between and within six eco-geographical groups of C. dactylon was estimated by Shannon's diversity index, which showed that 65.56% genetic variance existed within group, and 34.44% genetic variance was among groups. (4) Based on Nei's unbiased measures of genetic identity, UPGMA cluster analysis measures of six eco-geographical groups of Cynodon dactylon, indicated that there was a correlation between genetic differentiation and eco-geographical habits among the groups.

    Full Text Available Purpose. The purpose of this study is to evaluate the vision related quality of life in patients with keratoconus by using the National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25. Methods. Thirty patients presented with keratoconus (keratoconus group and 30 healthy patients (control group were included in this study. Twenty patients were using rigid gas permeable and 10 patients were not using contact lenses in keratoconus group. High and low contrast visual acuity and mean K values of the patients were recorded. Each subject completed the 25-item NEI-VFQ-25. Results. All subscales of NEI-VFQ-25 were lower in the keratoconus patients. The difference was more evident in the subscales of general vision, ocular pain, near vision, vision-specific mental health, vision-specific role difficulties, and peripheral vision P 0.4 in the better eye had lower distance vision, social functioning, mental health, and role difficulties. Meanwhile, patients with low visual acuity (logMAR > 0.4 in the worse eye had lower general health scores P<0.05. Conclusions. Vision related quality of life was worse in keratoconus patients. Success in the contact lens usage and maintaining higher visual acuity may improve vision related quality of life.

    To compare the impact of first eye versus second eye cataract surgery on visual function and quality of life. Cohort study. A total of 328 patients undergoing separate first eye and second eye phacoemulsification cataract surgeries at 5 veterans affairs centers in the United States. Patients with previous ocular surgery, postoperative endophthalmitis, postoperative retinal detachment, reoperation within 30 days, dementia, anxiety disorder, hearing difficulty, or history of drug abuse were excluded. Patients received complete preoperative and postoperative ophthalmic examinations for first eye and second eye cataract surgeries. Best-corrected visual acuity (BCVA) was measured 30 to 90 days preoperatively and postoperatively. Patients completed the National Eye Institute Visual Functioning Questionnaire (NEI-VFQ) 30 to 90 days preoperatively and postoperatively. The NEI-VFQ scores were calculated using a traditional subscale scoring algorithm and a Rasch-refined approach producing visual function and socioemotional subscale scores. Postoperative NEI-VFQ scores and improvement in NEI-VFQ scores comparing first eye versus second eye cataract surgery. Mean age was 70.4 years (±9.6 standard deviation [SD]). Compared with second eyes, first eyes had worse mean preoperative BCVA (0.55 vs. 0.36 logarithm of the minimum angle of resolution (logMAR), P < 0.001), greater mean BCVA improvement after surgery (-0.50 vs. -0.32 logMAR, P < 0.001), and slightly worse postoperative BCVA (0.06 vs. 0.03 logMAR, P = 0.039). Compared with first eye surgery, second eye surgery resulted in higher postoperative NEI-VFQ scores for nearly all traditional subscales (P < 0.001), visual function subscale (-3.85 vs. -2.91 logits, P < 0.001), and socioemotional subscale (-2.63 vs. -2.10 logits, P < 0.001). First eye surgery improved visual function scores more than second eye surgery (-2.99 vs. -2.67 logits, P = 0.021), but both first and second eye surgeries resulted in similar

    Full Text Available L'élevage pastoral est menacé au Sénégal car les dynamiques écologiques, les défrichements et les politiques publiques compromettent l'accès aux ressources sur lequel repose sa mobilité essentielle. Loin des clichés qui le présentent comme une activité homogène et archaïque, l'élevage connaît pourtant des mutations importantes. Sous des formes variées, il se diversifie et se connecte aux marchés urbains nationaux du lait et de la viande, valorisant des marchés de niche. Les dynamiques observées dans le plus urbanisé des États du Sahel préfigurent ainsi celles qui s'amorcent ailleurs.
