  1. 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.

  2. Municipal waste management in the urban areas; La gestione dei R.S.U. nei centri urbani

    Energy Technology Data Exchange (ETDEWEB)

    Andreoni, Piero [ENEA, Coordinamento Funzioni di Esercente, Rome (Italy); Capalbo, Anna [Gruppo ENI, Rome (Italy)

    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.

  3. Organismo territoriale e annodamenti urbani. Metodi di progetto per i centri minori del Lazio / Territorial organism and urban knottingt. Design methods for minor centers of Lazio

    Directory of Open Access Journals (Sweden)

    Giuseppe Strappa

    2013-07-01

    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

  7. Nesting biology of Centris (Centris aenea Lepeletier (Hymenoptera, Apidae, Centridini

    Directory of Open Access Journals (Sweden)

    Cândida Maria Lima Aguiar

    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.

    2014-01-01

    International audience; Centris flavifrons is a ground-nesting solitary bee species that has an important role in crop and native plant species pollination in the Neotropical region. However, the nesting biology and ecology of this species are little understood. We studied the nesting biology of C. flavifrons by observing 287 nests in an urban garden. Females built nests only during the dry season from September to March and exhibit notable flexibility in the amount of time each nest is activ...

  19. Crowdfunding per il Patrimonio Culturale nei Centri Storici Minori: la Chiesa di San Michele a Savoca

    Directory of Open Access Journals (Sweden)

    Antonino Cosentino

    2016-08-01

    Full Text Available Questo articolo illustra la campagna di crowdfunding “Save the Soul of Savoca” per finanziare il restauro di un ciclo di dipinti settecenteschi nel piccolo borgo di Savoca (ME. 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.

  15. Peracetic acid as disinfectant of municipal wastewaters; L'acido peracetico nella disinfezione dei reflui urbani

    Energy Technology Data Exchange (ETDEWEB)

    Funari, E. [Istituto Superiore di Sanita' , Laboratorio di Igiene Ambientale, Reparto di Medicina Ambientale, Rome (Italy); Lopez, A. [Consiglio Nazionale delle Ricerche, Istituto di Ricerca sulle Acque, Reparto di Chimica e Tecnologia delle Acque, Bari (Italy)

    2000-09-01

    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. [Italian] Il presente lavoro, basandosi sui dati disponibili in letteratura, si propone di fare il punto sull'impiego dell'acido peracetico (CH{sub 3}COOOH{identical_to} PAA) come disinfettante di reflui urbani depurati.

    International Nuclear Information System (INIS)

    2001-01-01

    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

  6. Nuclear Energy Institute (NEI) summary

    International Nuclear Information System (INIS)

    2001-01-01

    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

    Full Text Available Nests of Centris tarsata Smith, 1874 were obtained from trap-nests in areas of dry semi-deciduous forest (Baixa Grande and caatinga (Ipirá, in the State of Bahia. Nesting occurred in bamboo canes and in tubes of black cardboard with 5.8 cm (= small tube and 10.5 cm (= large tube in length and 0.6 and 0.8 cm in diameter, respectively. In both areas C. tarsata nested during the wet season producing four generations in Baixa Grande and three generations in Ipirá. The immatures of one generation underwent diapause at both sites. The bees constructed their nests with a mixture of sand and oil. In general, the cells were elongated and arranged in linear series with its opening pointing towards the nest entrance. Completed nests had two to three cells in small tubes, one to seven cells in large tubes, and two to 13 cells in bamboo canes. The nest plug resembled an uncompleted cell and was externally covered with oil. The cells were provisioned with pollen, oil, and nectar. Nests were parasitized by Mesocheira bicolor (Fabricius, 1804 (Hymenoptera: Apidae and other not identify bee species.Ninhos de Centris tarsata Smith, 1874 foram obtidos através da utilização de ninhos-armadilha, em áreas de floresta estacional semi-decídua (Baixa Grande e de caatinga (Ipirá, no Estado da Bahia.

    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.

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.

    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. (H. trigonoides apresentaram comportamentos defensivos para evitar parasitismo, tais como expulsar os parasitas e guardar os ninhos. Machos de C. (H. trigonoides usaram o local de nidificação como abrigo durante as horas mais quentes do dia, assim como para dormir. Eles deixavam as cavidades no dia seguinte entre 09:00 e 10:30 h. Isto sugere que machos e fêmeas têm padrões temporais de atividade distintos.The nesting behavior of Centris (Hemisiella trigonoides Lepeletier, 1841, and the behavior of their cleptoparasites were studied at Monte Santo, Bahia, Brazil.

    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.

    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.

    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.

    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

    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.

    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.

    The purpose of this work is to define the state of the art about the problem of the indicators and their capability in reading and foreseeing the urban complexity. Therefore, the theoretical elaborations and the suggestions developed in the report try to convert the different contributions in the Italian and international literature in a frame-work, focusing on those arguments which assume a key role in the study of the urban areas: (a) the problematic definition of the administrative, physics and functional boarders of the cities; (b) the selection of the indicators that describe the urban areas; (c) the description and quality of life and of environment quality in the cities; (d) the sustainability in urban areas. [Italian] Il lavoro si propone di delineare lo stato dell'arte sul problema degli indicatori e sulla loro capacita' di leggere e prevedere la complessita' urbana. Le elaborazioni teoriche e i suggerimenti metodologici sviluppati nel rapporto tentano dunque di tradurre in protocolli di lavoro i diversi contributi prodotti negli ultimi anni nella letteratura italiana e internazionale concentrando in particolare l'attenzione su quei temi che all'interno dello studio dei sistemi urbani assumono un ruolo chiave: (a) la problematica definizione dei confini amministrativi, fisici e funzionali delle citta'; (b) la selezione degli indicatori che descrivono con piu' efficacia il sistema urbano; (c) le dimensioni e la misura della qualita' della vita e dell'ambiente nelle citta'; (d) la sostenibilita' all'interno dei sistemi urbani.

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)

    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.

    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.

    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 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.

    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.

    Obiettivi: nell’ASLdi Brescia durante i mesi di gennaiomaggio 2003 si è verificato un consistente aumento di casi di meningite che ha allarmato oltre agli operatori sanitari anche l’opinione pubblica locale.

    Metodi: i dati riguardanti i casi di meningite verificatisi dal gennaio 1999 al maggio 2003 sono stati raccolti dal Servizio Igiene Pubblica dell’ASLdi Brescia.

    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

    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.

    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.

    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. Identification of the isolated proteins was performed by

    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.

    The purpose of this work is to define the state of the art about the problem of the indicators and their capability in reading and foreseeing the urban complexity. Therefore, the theoretical elaborations and the suggestions developed in the report try to convert the different contributions in the Italian and international literature in a frame-work, focusing on those arguments which assume a key role in the study of the urban areas: (a) the problematic definition of the administrative, physics and functional boarders of the cities; (b) the selection of the indicators that describe the urban areas; (c) the description and quality of life and of environment quality in the cities; (d) the sustainability in urban areas. [Italian] Il lavoro si propone di delineare lo stato dell'arte sul problema degli indicatori e sulla loro capacita' di leggere e prevedere la complessita' urbana. Le elaborazioni teoriche e i suggerimenti metodologici sviluppati nel rapporto tentano dunque di tradurre in protocolli di lavoro i diversi contributi prodotti negli ultimi anni nella letteratura italiana e internazionale concentrando in particolare l'attenzione su quei temi che all'interno dello studio dei sistemi urbani assumono un ruolo chiave: (a) la problematica definizione dei confini amministrativi, fisici e funzionali delle citta'; (b) la selezione degli indicatori che descrivono con piu' efficacia il sistema urbano; (c) le dimensioni e la misura della qualita' della vita e dell'ambiente nelle citta'; (d) la sostenibilita' all'interno dei sistemi urbani.

    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 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

    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.

    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

    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

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%.

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.

    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.

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.

    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

    Full Text Available L’articolo prende in esame la presenza di tematiche e strutture assimilabili all’estetica del tragico nelle opere di Marcel Proust e James Joyce,. Vengono in primo luogo confrontate le riflessioni sulla tragedia e sul concetto di tragico degli autori; successivamente viene considerato l’influsso esercitato da opere come la Phèdre di Racine e l’Hamlet shakespeariano, sia al livello di rimandi intertestuali nelle opere, che le loro effettive risonanze nei caratteri e trame della Recherche e di Ulysses. Si cerca infine di comprendere come il significato tragico degli eventi venga rielaborato al di là delle sue implicazioni estetiche.

Relative growth performance, thus, can be understood by looking to income elasticities of demand for exports and imports. This insight into the process of income determination in open economies, found in Harrod as well as in the literature on economic development, is developed through so-called centre-periphery models of growth and development. However, their essential conclusions were already contained in the early classic papers.

    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). Le finalita' del sistema: massimizzare i livelli di intercettazione e recupero delle frazioni riciclabili

    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.

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. CONCLUSÃO: A maior dependência social e na realização de atividades do dia-a-dia no grupo de uveítes de causa não infecciosas, se explica pelo modo crônico e recidivante dessas afecções, o que leva à qualidade de vida inferior se comparada ao outro grupo.PURPOSE: To evaluate the life quality of patients with infectious and non-infectious uveitis evaluated at the uveitis service of the Hospital Universitário Clementino Fraga Filho-UFRJ, using the NEI-VFQ-25 questionnaire in order to clarify the importance of uveitis diagnosis and treatment as well as its consequences to visual and social functions of the patients.

    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. 

  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.

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.

    ,8 anni sono stati valutati sia con TC che con ecografia. E' stato determinato il valore assoluto del grasso intra-addominale, sottocutaneo e totale, espresso in cm{sup 2,} sulla base delle elaborazioni TC. Con l'ecografia sono state valutate le distanze tra il muscolo retto e la colonna vertebrale e tra il muscolo retto e l'aorta, senza e con compressione dosata, quali parametri indicativi dello spessore del grasso viscerale nonche' la distanza tra cute e muscolo retto quale indicatore del grasso sottocutaneo. I risultati dell'ecografia e della TC sono stati inoltre correlati con altre variabili morfometriche (peso, peso corporeo ideale, plicometria cutanea). E' stata dimostrata correlazione statisticamente significativa tra la quota di grasso viscerale misurato con la TC e le distanze muscolo retto/aorta (r=0,80) e muscolo retto/colonna vertebrale (r=0,74). Anche l'area sottocutanea misurata con la TC si correlava (r=0,82) con la distanza cute/muscolo retto valutata ecograficamente. Non e' stata riscontrata alcuna correlazione tra l'indice di massa corporea e i dati ecografici e TC. I risultati ottenuti suggeriscono che l'ecografia puo' essere utilizzata in alternativa alla TC nella valutazione della distribuzione del grasso corporeo nei bambini obesi.

    cerebrale, retro-orbitaria e splancnica (splenoportale, mesenterica e renale) nei pazienti derodermici. Materiale e metodi. Il gruppo di studio (GS) e composto da 50 pazienti affetti da sclerodermia con anamnesi negativa per malattie cerebrovascolari, epatopatie, nefropatie e oftalmopatie. In tutti i pazienti e stata studiata la vasodilatazione endotelio-mediata dell'arteria brachiale tramite la misurazione del diametro trasverso con sonda ad alta risoluzione; sono stati anche misurati l'indice di resistenza (IR) delle arterie cerebrale media, centroretinica, epatica propria, mesenterica superiore e renali, in condizioni basali e dopo tre giorni di terapia. AI fine di valutare la variabilita intra-osservatore delle misurazioni, e stato reclutato un gruppo di controllo (GC) composto da 10 volontari sani che sono stati studiati con il medesimo protocollo Doppler e rivalutati a distanza di tre giorni senza ricevere alcuna terapia. Risultati. Il GS ha dimostrato un significativo incremento della dilatazione endotelio-mediata dell'arteria brachiale, del diametro e della velocita media di flusso portale, dell'IP dell'arteria splenica all'ilo (pre-Prostavasin vs post-Prostavasin, p < 0,001). AI contrario il GC non ha mostrato significative variazioni dei parametri considerati. Gli IR delle arterie cerebrale media, centroretinica, renale, epatica propria e mesenterica superiore si sono ridotti dopo terapia nella maggioranza dei pazienti del GS pur non risultando statisticamente significativi. Conclusioni. Nel campione esaminato il Prostavasin ha dimostrato una potente azione vasodilatatoria prevalentemente a livello periferico ed ha incrementato la velocita media di flusso portale ed il diametro della vena porta, ma anche l'IP dell'arteria splenica all'ilo, non supportando l'ipotesi formulata da altri autori di una sua azione mirata e specifica sulle resistenze intraepatiche.

    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 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

    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.

    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.

    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.

    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.

    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 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.

    La progettazione dei sistemi fognari e dei manufatti in essi presenti richiede un’attenta conoscenza delle leggi che regolano i fenomeni idraulici, con particolare riferimento alle correnti idriche a superficie libera. Partendo dalle nozioni fondamentali dell’Idraulica, il testo intende colmare alcune importanti lacune che ancora caratterizzano la letteratura italiana nel settore e che spesso sono alla base di errori progettuali, con ovvie conseguenze sulla sicurezza dei centri abitati (come testimoniato dai frequenti fenomeni di allagamento che sono stati registrati negli ultimi anni). Il libro è rivolto agli allievi dei corsi di studio nel settore dell’ingegneria Civile ed Ambientale. Particolare interesse è rivolto ai professionisti operanti nel settore della ingegneria idraulica e della pianificazione urbana, per i quali è forte l’esigenza di testi che contengano indicazioni di carattere sia teorico sia pratico, finalizzate alla progettazione di sistemi di drenaggio nei centri abitati.

    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.

    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 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.

    Full Text Available INTRODUZIONE: I rifugiati richiedenti protezione internazionale mostrano un'alta vulnerabilità e Disturbo Post-Traumatico da Stress (PTSD. OBIETTIVI: abbiamo utilizzato un approccio integrato multidisciplinare per valutare la loro vulnerabilità e psicopatologia. METODI: sono stati valutati 180 rifugiati politici secondo i criteri del DSM-IV-TR. RISULTATI: in un'alta percentuale di rifugiati politici la diagnosi principale è stata di PTSD associata con disturbi di personalità e/o altri disturbi psichici. CONCLUSIONI: i rifugiati politici hanno più difficoltà nel gestire le proprie emozioni, questo probabilmente è dovuto alla propria storia personale intrisa di vissuti traumatici, tuttavia attraverso un lavoro sia psicoterapico che farmacologico è stato possibile migliorare le proprie condizioni.

    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.

Going beyond the analysis of prejudice in narrow cognitive terms, as a form of stereotype, its conceptualization presents itself as a result of pathological defense mechanisms. With this in mind, prejudice towards disability is re-read in light of massive defenses against not only diversity, but also against those who carry mental pain. The articles concludes with a reflection on the ways in which prejudice against disability can be fought in our society in order to promote genuine social change.

    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.

    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 One of the main debate topics between citizens and people who manage public property is urban quality of life. The project aims to evaluate the spatial distribution of basic primary services (such as pharmacies, doctors' offices and shops that sell all the basic necessities concerning people with reduced mobility, in order to provide cognitive tools in support of a land-use planning (managed by local authorities, which meets the needs of the resident population. We decided to consider the village of Tivoli. The city shows some service management issues, mainly due to the presence of two portions with reduced intermobility. As regards the analysis of population, starting from the sections of ISTAT data, we evaluated the distribution of the population characterized by reduced mobility in the different parts, related to the onset of chronic diseases in age groups above 60 years. This study aims to suggest local authorities to optimize the redistribution of the above-written services and to improve the accessibility for people with reduced mobility.

    The application of Life Cycle Assessment (LCA) methodology as environmental balance tool is particularly suitable for the study of complex system such as municipal solid waste (MSW) collection, treatment and disposal systems. In this case a detailed analysis is carried out referring to an overall environmental balance based on two different waste treatments: land filling and incineration. The comparison carried out based on the LCA methodology and referring to specific process assumptions allowed to foreground that waste to energy treatments get a net overall balance lower than all the different land filling options, referring also to energy recovery from collected biogas.

    Full Text Available In the perspective of the participatory programming, nowadays main-stream in all spheres of urban planning, the analysis of the parametric costs has been affirmed as an important design tool; it’s requested, at all levels, to increase the transparency and flexibility of the plan, and play an important role in the knowledge process for decision makers as well as for users and stakeholders. The experimental context of this study is the old town of Ragusa Superiore, a large urban fabric consisting of 8600 architectural units, quite homogeneous from the constructive point of view, but not from the typological and morphological ones. The analysis supports a strategic planning process based on the design of several option of intervention strategies (more conservative or transformative, envisaging a certain degree of flexibility in sorting the involved Architectural Units between the different Intervention Categories; in this role, the proposed pattern allows us to associate in real time the parametric cost to each of the different Intervention Categories supposed in each simulation. The parametric cost analysis is based on the typing of the analysed fabric, consisting of 1788 architectural units and provides a wide range of unit costs to indicate feasibility and convenience of the real estate investments in order to define a possible incentive program aimed at internalizing the urban externalities resulting from the more general process of enhancement of the entire old town.

    Use of extracorporeal membrane oxygenation (ECMO) for severe cardiopulmonary failure has increased because of improved outcomes. A specially designed ECMO transport system allows for safe transport of patients over long distances. We report a 28-year-old pregnant woman (26 weeks gestation) with acute respiratory distress syndrome in whom ECMO support was necessary for survival, and she was transported to another facility 1,155 km away with the aid of the portable ECMO system. Transport was uneventful, and the patient's condition remained stable. Acute respiratory distress syndrome improved gradually until the patient was discharged from the hospital with excellent maternal and fetal outcome.

  1. New health and environmental risks in water for a new centry Nuevo siglo, nuevos riesgos sanitarios y ambientales en el agua

    Directory of Open Access Journals (Sweden)

    Rafael J. García-Villanova Ruiz

    2003-12-01

    Full Text Available In those where appropriate water management and control have been implanted, hazards that have endangered Humanity throughout time have been reduced. Today, however, new threats are emerging, threats previously unknown, inexistent or considered irrelevant in the past.The so-called chlorination by-products of water are the other face of this landmark of the employ of chlorine as a disinfectant. Its drawbacks are by no means comparable to its benefits, but in a population with higher life expectancy and health standards, epidemiological studies have determined a higher cancer risk, to a variable certainty though.Consecuently, European Directive 98/83/CE has established a limit of 100 μg/l for the group of trihalomethanes. Compliance with this limit it’s been difficult for Spain as surface water is a main resource and, on the other hand, its warm climate favours its formation.Extensive experiments on water fluoridation in United States and Central and Northen Europe showed, to a varying extent, a positive effect on dental caries. However, there is an increasing opinion on its side-effects with a result of both dentine and skeletal fluorosis. A number of authors state that even the current recomended dose in drinking water (1,0 to 1,5 g/l could be deletereous. Controversy has raised throughout the last decade and has led to a tendency for suppression.During the last quarter of the XXth century groundwater monitoring plans have revealed that arsenic is present more frecuently than it was thought. The best known episode is that of Taiwan, with a result of some 10.000 cases of melanodermic syndrome and skin cancer. Since animal studies had failed in demostrating a cancer induction or promotion with arsenic, the overwhelming records of that episode have permitted a risk estimation and, then, proposal for the new standard of 10 μg/l. A most tragic episode is that recent of Bangla-Desh, with more than 40 millions individuals affected of chronic intoxication, many of them with skin, lung and bladder cancers.Coastal and continental water eutrophycation is a broadly generalized phenomenon, which affects Spain too. There is a recent concern about it because toxigenic algal blooms are more and more frequent. There is an estimation that half of them have produced neuro or hepatotoxins in dams and backwaters. The surface accumulation of some species of blue-green algae with crusts or foams by the shore is been known as a cause for lethal intoxication of cattle. More frequently can be found human episodes with eyes irritation, rashes, vomiting, dyarrhea, fever and muscular and articulation pain in individuals after drinking or bathing in waters with foams from algae. The new spanish regulation stablishes a control for microcystine, with a limit of 1 μg/l.Waste waters may hold up to 100 especies of human pathogenic viruses. They usually cross through sewage treatment plants and survive in the water bodies for large periods, thus reaching the drinking water plants were they are not affected by the chlorine. However, only for a few there is evidence of transmission through water, as with the case of the Hepatitis A and E viruses. On the other hand, currently viral gastroenteritis is the second cause of infectious disease in developed countries. The agents are considered to be Rotavirus and Norovirus (Norwalk-like viruses with a hydric transmission.For years, Cryptosporidium has been considered an animal parasite, especially of cattle. In 1976 it was first recognized as a human pathogen, but not until 1983 it was documented the first epidemic transmitted by the water. In 1993 a big epidemic was declared at Milwaukee (Wisconsin with some 400.000 affected, after ingestion of water from a distribution system which showed to comply with all the legal standards. In inmunosuppressed patients, the infection is severe and with a high rate of death among those affected by SIDA. Conventional chlorination does not affect the oocyst, although much of them (but not always and not all are rettained by the filters. The risk and lack of safety is a fact, because the infective dose could be between 1 and 100 oocysts.Allá donde se ha impuesto una correcta gestión y control de las aguas han quedado minimizadas las amenazas que durante siglos pesaron sobre la humanidad. Sin embargo, nuevos riesgos emergen en la actualidad, unos inexistentes antes y otros desconocidos o considerados de escasa relevancia para las prioridades sanitarias del pasado.Los llamados subproductos de cloración de las aguas son la cara menos amable de este hito que ha supuesto el empleo del cloro como desinfectante. Sus inconvenientes no son desde luego comparables a sus beneficios, pero en una población que aspira y ya posee mayor esperanza de vida y mejores estándares sanitarios, los estudios epidemiológicos han establecido con desigual certeza un mayor riesgo de cáncer. Por ello la Directiva Europea 98/83/CE limitó el contenido en el grupo de los trihalometanos a 100 μg/l, con abastecimientos de agua en su mayoría de origen superficial y, está planteando un verdadero problema el cumplimiento de este límite.A pesar de las ingentes experiencias de fluoración de aguas en plantas potabilizadoras de Estados Unidos y Norte y Centroeuropa durante la segunda mitad del siglo XX, de resultados aparentemente positivos en la prevención de la caries dental, recientemente ha vuelto la controversia acerca de sus efectos nocivos no sólo sobre la dentadura y esqueleto (fluorosis sino sobre diversos mecanismos metabólicos. Ya se afirma que puede ser nocivo incluso a la concentración en que se recomienda (1,0-1,5 μg/l, lo que en los últimos años ha producido una corriente partidaria de su supresión.En las últimas décadas del pasado siglo, los planes de monitorización de aguas subterráneas han revelado que el arsénico está presente de forma más frecuente de lo que se pensó. El caso mejor estudiado es el de Taiwan, con unos diez mil casos de síndrome melanodérmico y cáncer cutáneo. La abundante documentación de este suceso y la aplicación de una metodología singular de estimación de riesgos (la toxicología del arsénico no ha encontrado un modelo experimental animal impulsó recientemente el nuevo estándar de 10 μg/l por OMS y EPA reflejado en nuestra nueva legislación. Pero el caso más reciente y trágico es el de Bangla-Desh, con más de 40 millones de afectados de intoxicación crónica.La eutrofización de las aguas continentales y costeras es un fenómeno muy generalizado, que alcanza también a nuestro país. Preocupa en la actualidad porque son cada vez más frecuentes las llamadas floraciones (“blooms” de algas cianofíceas toxigénicas. Se estima que más de la mitad de ellos han producido neuro o hepatoxinas en embalses y aguas remansadas. La acumulación superficial (“mantas” de algunas especies de cianofíceas o de costras y espumas en las orillas han sido causa de intoxicación letal del ganado. Más corriente es la irritación de ojos, erupciones cutáneas, vómitos, diarrea, fiebre y dolor en músculos y articulaciones en personas que han bebido o bañado en lugares con espumas procedentes de algas. Aunque no lo estipula la Directiva Europea, la nueva legislación española prescribe acertadamente el control de una de ellas: microcistina, 1ppb.En las aguas residuales urbanas pueden estar presentes hasta 100 especies de virus patógenos para el hombre. Suelen pasar las plantas depuradoras de residuales sin verse afectados y sobrevivir en el medio acuático durante largos períodos, y así llegan a las plantas de potabilización convencionales, donde generalmente resisten la cloración. Sin embargo, sólo de unos pocos se ha demostrado su transmisión por el agua. Es el caso del de la Hepatitis A y, más recientemente, el de la Hepatitis E, endémicos en la región mediterránea. De otra parte, en la actualidad la gastroenteritis viral es la segunda causa de enfermedad infecciosa, después de las respiratorias, en países desarrollados y se atribuye fundamentalmente a Rotavirus y Normovirus (virus Norwalk like, con la vía hídrica como forma de transmisión.Cryptosporidium siempre ha sido un parásito de animales, incluyendo los de compañía y granja. Sin embargo, en el año 1976 se reconoció como patógeno humano y la primera epidemia documentada que tuvo por origen el agua es aún más reciente, 1983. El brote epidémico más espectacular fue el de la primavera de 1993 en Milwaukee (Wisconsin, con 400.000 infectados por un agua municipal que cumplía todos los estándares legales.

La inseguridad es, pues, grande porque la dosis infectiva podría estar entre 1 y 100 ooquistes.

    Full Text Available Il dibattito sull’ambiente antico e sull’inesauribile varietà di approcci che ne qualificano gli interventi di tutela riabilitazione è un tema che si ripresenta ciclicamente e con profili sempre diversi. Attraverso lo studio delle politiche di tutela, delle esperienze amministrative e della prassi di governo del patrimonio storico, dal primo dopoguerra agli anni Settanta, si può cercare di comprendere quali sono i presupposti che hanno portato a collocare il tema della tutela entro quella nuova cultura della città, sorta in ambito al dibattito urbanistico nazionale e che ha assunto il tema specialistico della tutela come campo di sperimentazione per la ridefinizione delle più ampie strategie di amministrazione della città, con progetti finalizzati alla conservazione del tessuto urbano storico nella sua globalità. Con il Piano per il centro storico di Bologna del 1969 e il successivo Peep del 1973, nonché con le vicende amministrative che ne hanno accompagnato l’attuazione e la gestione per più di venti anni, il centro storico diventa al contempo un campo di sperimentazione di politiche urbanistiche, politiche sociali e politiche di tutela del patrimonio storico. Nel mirare ad una tutela multidimensionale dei tessuti storici, i programmi elaborati dalle pubbliche amministrazioni hanno comportato la necessità di spostare il fuoco del progetto urbanistico per i tessuti storici verso una difficile integrazione tra istanze di conservazione dell’ambiente costruito, dei suoi manufatti e dello spazio collettivo, ed esigenze di governo complessivo delle dinamiche di trasformazione ed uso della città. The debate on urban renewal of historical city centers continues to propose new arguments, connected to the difficulties carried on by new uses demands, that carry on an equal variety of technical instruments and political options. A long period reconstruction of significanti italian conservation policies for ancient cities - from the Second World War to the Seventies - sould be useful to understand how a new culture of the city arose in Italy, enabling the definition of cultural and technical tools better able to achieve a whole conservation of historical urban environment. With the plan for the historical center of Bologna in 1969, and the subsequent public-housing program of 1973, the city center becomes the symbol of a new way of managing urban and social transformations within the ancient settlements, paying attention both to the permanence of its natural population, through encouraging a participatory planning process and collective involvement in public decisions, and the survey of historic built environment and its features. This allowed the effective revitalization of historical urban tissues, taking into account at the same time the artifacts, the elements which constitute the exterior and interior of urban spaces and the behavioural processes of local subjects, in order to accomplish an harmonious and efficient development of the entire urban structure.

    Full Text Available In the last decades, we have seen a rapid growth in the culture of prevention, safety and care for people involved in dramatic events. These calamites, both natural and human made, can have a profound effect on the mental stability of individuals and communities. These effects can have consequences on people, which may go on for days, months and even years during the recovery, rebuilding and re-establishment of an ordinary situation. Each event due to these circumstances is an emergency from a technical-practical and also human point of view. And that is because people are forced to fight in order to survive physically and emotionally in a state of dangerousness and dramatic force. During an emergency it is necessary to help people recognize normality in their own reactions, which are consequences of a situation out of ordinary. A greater focus on the emotional and cognitive component of the person involved is needed. Actually, this component proves to be very important both for the successful management of the situation - being involved in the prevention and preparation phases - and for its contribution to a mitigation of the effects of a specific event. It is widely known that during an emergency, interventions by psychologists trained to face various contexts (e.g., incidents, natural disasters and so on and able to cooperate with other professionals are needed. The aim is to promote in the people involved, both rescuers and victims, the capacity to cope with the situation, in the short term and in the long term.

    2016-12-01

    Full Text Available The article focuses on the rise of third-worldism as a form of political solidarity with many decolonization conflicts spread in the 1950s and 1960s and its transformation in a one-sided idea of anti-imperialism that put the US foreign politics at the centre of the international stage. This kind of selective criticism – addressing the so-called yankee imperialism – grounded principally on the US military intervention in Vietnam since 1965 but eventually it evolved in a kind of ideological paradigm that made of the USA the unique cause of all problems affecting states emerged from decolonization. This ideological turn hindered a deep and wide understanding of the complex and manifold forms of entanglements that followed, replaced and in some cases occurred as new factors within the world order established in the second half of the 20th century.

    Full Text Available L’evoluzione storico-musicale nella prima metà del Quattrocento è caratterizzata dall’internazionalizzazione della cultura musicale europea ed si pone in continuità con il processo culturale del primo umanesimo. La categoria di ‘evoluzione’ e l’idea stessa di ‘rinascita’, ovvero quella “leggenda di un progresso” (Martin Le Franc, Johannes Tinctoris discussa da Reinhard Strohm, sono concetti che oggi devono essere letti non soltanto nel senso di una omologazione stilistica, ma anche come aspetto distintivo di una ricerca d’identità culturale. Anche dal punto di vista storico-musicale siamo di fronte alla costituzione di un nuovo gusto europeo nato dalla fusione di stili e di pratiche locali che si espanderà, grazie alla trasmissione delle compilazioni manoscritte, per tutto il continente e al quale aderiranno, in maniera disomogenea, anche compositori di regioni più remote.Il Concilio di Basilea non costituisce solo un dato storico circoscrivibile agli anni in cui si svolse il sinodo, così come non è da considerarsi solo un fatto empirico riguardante la sola città della Svizzera settentrionale. Esso deve piuttosto essere assunto come un evento paradigmatico per la storia della cultura del Quattrocento. Gli incontri fra intellettuali ed artisti, l’interazione fra musicisti di diverse regioni europee che si incontravano grazie ai frequentissimi spostamenti delle corti e delle cappelle, fanno del Concilio la piattaforma virtuale sia per la ricerca di una nuova identità culturale sia per la nascita di nuovi repertori e pratiche musicali. Il Concilio trascende quindi i confini contingenti della città di Basilea trasformandosi in una vera e propria “dinamica culturale” in cui i singoli individui contribuiscono alla continua trasmissione e fusione di esperienze musicali diventando vettori di una nuova mentalità musicale che raggiunse anche gli angoli più remoti dell’Europa.

    Full Text Available I paesaggi culturali rappresentano una risorsa fondamentale per lo sviluppo sostenibile. Tra questi, i paesaggi terrazzati sono classificati come paesaggi culturali “evolutivi viventi” (UNESCO, 2012, espressione della storica interrelazione tra uomo e territorio. Attualmente molti paesaggi terrazzati sono considerati a rischio a causa delle mutate condizioni socio-economiche. L’esigenza della conservazione e di una gestione efficace di questo eccezionale patrimonio pone la questione dell’identificazione di funzioni e valori complessi del paesaggio, tenendo conto di bisogni, visioni e preferenze delle comunità locali. Questo studio ha l’obiettivo di identificare valori e servizi del paesaggio terrazzato sulla base della teoria dei servizi ecosistemici. Viene affrontato il tema della valutazione e mappatura dei servizi culturali, con riferimento al paesaggio terrazzato della Costiera Amalfitana in Campania. Le categorie di servizi sono state valutate con il coinvolgimento della comunità locale attraverso un questionario semi-strutturato somministrato online ad un campione di 147 soggetti. L’integrazione tra valutazione multicriterio e analisi spaziale in ambito GIS (Geographic Information System ha condotto alla costruzione di mappe dei servizi culturali che permettono di visualizzare in maniera sintetica le relazioni complesse che legano l’uomo al paesaggio. Gli strumenti di mapping collaborativo (Volunteered Geographic Information – VGI sono stati utilizzati per la costruzione di alcune delle mappe dei servizi culturali, integrando i risultati del questionario con i dati relativi all’esperienza diretta degli utenti.

    Directory of Open Access Journals (Sweden)

    Giuseppe Langella

    2014-02-01

    Full Text Available In order to tell the story of the conversion of the Conte del Sagrato in Fermo e Lucia, Manzoni adheres to the Pauline model of a sudden shock, thus interpreting the event as a miraculous event in which the redeemed sinner’s role remains completely passive. In The Betrothed, however, the whole episode is being rewritten from the Augustinian model of the Confessions, which represents conversion as a slow and gradual process of crisis, full of anxiety, inner conflict, dejection and resistance, in which God calls for repentance, creates favourable opportunities, eliminates inner anguish and offers necessary help, while respecting human timing, nature and freedom. This essay reconstructs, step by step, all the stages of the conversion of the Unnamed, from his first appearance in the novel to his exit, highlighting the psychological as well as moral turning points of the process of conversion, not without repeated references to the other converts in the novel, starting with Fra Cristoforo, and Napoleon in the Fifth of May.

    Directory of Open Access Journals (Sweden)

    C. COSCIANI

    2014-07-01

    Full Text Available The arguments for progressive taxation in the nineteenth century were strongly countered by reference to their harmful effects on the incentives to produce, save and invest. This position is still fairly widespread in discussions on what makes a sound fiscal policy for the underdeveloped countries today. The present article argues that progressive taxation corrects the maldistribution of national income, producing additional positive effects in a depressed economy in the process of development, especially as regards investment and the balance of payments. The considerations set out by the author suggest that in underdeveloped countries, progressive taxation must therefore not be regarded only from the point of view of national finance, but from that of the redistribution of income.JEL: E24, E62, H21, O15, F32

The primary purpose of the study is to investigate the rhetorical structuring of the narrative in an ethnopoetic perspective (Hymes 2003, and to identify the presence (or, even more significantly, marked absence of dialogic signs of intercultural negotiation deployed in the process of conveying to a culturally diverse audience a highly culturally situated story embedded in a personal narrative of displacement. At the same time, the study also intends to contribute to the current debate on English as a Lingua Franca (ELF by addressing the issue of the inherently situated nature of ELF, and of the political and ideological implications of an ELF approach to intercultural communication in both asymmetric and (programmatically symmetric power situations. The video selected for the analysis was retrieved from the UNHCR Youtube channel and is part of a series called Storytelling: through the eyes of Refugees designed to make refugees’ stories known to the wide public and to legitimise refugees as a category of people endowed with agentivity and self-determination, and with the power of contributing to the discursive construction of their own role and status. Because of their global outreach, these videos qualify as instances of ELF usage in a broad international context and are eminently suited to the investigation and discussion of ELF approaches to conventionally asymmetric institutional communication.

  4. Rovesciamento e alterazione nei racconti Uranio, Vanadio e in Auschwitz, Città Tranquilla

    Directory of Open Access Journals (Sweden)

    Fausto Maria Greco

    2016-11-01

    Full Text Available Ne Il sistema periodico accade che i processi dell’alterazione e del rovesciamento investano le funzioni stesse della narrazione e della testimonianza. In Uranio il personaggio di Bonino, narratore inattendibile, è un doppio rovesciato di Primo Levi. Egli realizza uno degli incubi dello scrittore torinese, quello di raccontare l’esperienza vissuta nel lager e di non essere creduto, ma l’effetto di rovesciamento riguarda anche altri versanti della scrittura. Come Elie Wiesel nel racconto intitolato Barbara, incluso nella raccolta de L’ebreo errante del 1966, Levi prende le distanze, in Uranio, da una memoria che falsifica, che oltrepassa la barriera della verità per costruire un’immagine eroica dei sopravvissuti. Nell’opera di Levi le figure di doppi rovesciati segnalano rischi incombenti, ipotesi inquietanti; i processi di alterazione, invece, si adattano meglio allo sforzo di conoscenza che riguarda l’universo concentrazionario. In questo rapporto stanno il Bonino di Uranio e il Cerrato di Argento, il dottor Müller di Vanadio (ancora ne Il sistema periodico e l’ingegner Mertens del racconto di Auschwitz, città tranquilla (pubblicato nell’84 e aggiunto ai Racconti e saggi. Dietro i nomi di Müller e di Mertens si celano, però, figure in carne e ossa con le quali lo scrittore è entrato in contatto. Il capovolgimento rivela un’ipotesi provocatoria, una vertigine del pensiero, nel caso di Mertens; l’alterazione apre alla conoscenza etica nella vicenda di Müller.The study focuses on the methods of alteration and overturning that influence functions of narration and testimony in Primo Levi’s Il sistema periodico (1975. In the short story Uranio, the character of Bonino is an unreliable storyteller as well as an overturned double of the writer. Bonino represents one of Levi’s obsessions, i.e., not being believed when telling the experience of prison and extermination camps. The effect of overturning also regards other aspects of Levi’s writing: as in the case of Elie Wiesel in the novel Barbara, published in the collection Le chant des morts (1966, in Uranio Levi distances himself from the use of memory that distorts its contents and crosses the borders of truth in order to describe survivors as heroes. In Levi’s works, such overturned doubles as Bonino reveal menacing risks and disturbing events. Conversely, the processes of alteration and distortion which can be inscribed to the character of Cerrato, in the short story Argento, better conform to the writer’s struggle for knowledge of the universe of extermination camps. Beside Bonino and Cerrato, the same comparison can be established between Doktor Müller of Vanadio and the chemical engineer Mertens of Auschwitz, città tranquilla (published in 1984 and included in the collection Racconti e saggi. These characters are based on people Levi really met or dealt with. By analyzing Vanadio and Auschwitz, città tranquilla, the study aims to show how, as for Mertens, overturning reveals a provocative hypothesis, while alteration contributes to ethical knowledge in the case of Müller. PAROLE CHIAVEPrimo Levi; Elie Wiesel; rovesciamento; alterazione; narratore (attendibile/inattendibile; narrazione; testimonianza; doppio; lager; memoria.

    Directory of Open Access Journals (Sweden)

    Silvia Lelli

    2014-04-01

    Full Text Available After a short theoretical introduction that highlights how field research in public street markets provides a contribution to economic-anthropological theories, street markets turn out to be characterized by a dense social interaction, and by complex intersections of multidirectional policies: within them, the effects of economic and administrative macro-policies imposed 'from above' are visible and, at the same time, in reverse, we can detect here aspects of the local social construction that from grass root level influences the exterior, both in forms of organized resistance against disadvantageous imposed policies, and by spontaneously shaping the social interaction pattern and the identity of the urban neighbourhoods where markets are sited. As arenas in which the possibility and the ability 'to negotiate' symbolic as well as economic values is constantly reproduced, the cultural 'immaterial' component of 'material' life is evident in public markets. As contexts in which different economies – capitalist and non-monetary, formal and informal, where the gift is a social and commercial strategy – are simultaneously ongoing, as spaces of interaction between highly heterogeneous socio-economical classes, between solidarity and exploitation, consumerism, reuse and saving, street markets are aggregates of apparently contradictory, but complementary social qualities. Such ‘disorder’ often makes them target of gentrification, transformation or limitations attempts, but the complexity of their polyhedral configuration seems to guarantee their persistence in history, as resistant forms of socioeconomical exchange, and rare contexts of urban social construction.

    Full Text Available Stoccaggio e trasporto merci hanno assunto, già da alcuni anni, un ruolo rilevante nell’area orientale di Napoli, con impatti significativi sulla qualità urbana ed ambientale dell’area. In quest’area, anche grazie alla sua vicinanza ai principali nodi della mobilità (porto, aeroporto, stazione ferroviaria e alla significativa presenza di aree produttive dismesse o in dismissione, trovano oggi spazio numerose attività di stoccaggio e spedizione merci, in molti casi localizzate all’interno di ex aree industriali, in assenza di una reale ottica “sistemica”. Pertanto, a partire da una breve disamina dell’evoluzione dell’area orientale e di quanto previsto dagli strumenti urbanistici vigenti per la sua trasformazione, il contributo focalizza l’attenzione sul ruolo attuale dslle attività di stoccaggio e trasporto merci nell’area. Quindi, sulla base di alcune recenti esperienze di italiane e in riferimento ad ipotesi già avanzate per l’organizzazione di una piattaforma logistica nell’area orientale di Napoli -quale strumento per ottimizzare le necessità di stoccaggio e trasporto merci riducendone le esternalità negative- valuta la compatibilità di tali scelte con le prospettive di evoluzione/trasformazione dell’area e il potenziale ruolo che l’area potrebbe svolgere in una prospettiva di ri-organizzazione del trasporto merci in ambito urbano.

    2002-03-01

    Full Text Available Alprazolam is a triazolo analog of the 1,4 benzodiazepine class, widely used to treat patients with anxiety disorder, panic attacks and anxiety comorbidity with depressive disorder. Following oral administration, alprazolam is readily absorbed with peack plasma levels in 2 hours; extensive hepatic metabolism occurs and about 80% of the oral dose is excreted by kidney. The main metabolic route is hydroxylation catalyzed by cytochrome P450 3A: alpha-hydroxy alprazolam is partially active. Alprazolam possesses anxiolytic properties similar to other benzodiazepines; however, the triazolo ring confers to alprazolam a peculiar antidepressant and antipanic activity.

    Full Text Available In a wide-ranging theoretical framework, principally based upon discourse analysis and the studies on language and identity, this article explores the construction of identity in a corpus of oral narratives collected among the Spanish speaking communities in Milan, by means of sociolinguistic and biographic interviews, seen as a complex event in which both parties act as active participant-observers. The study focuses on the features of these life stories, taking into account the ways in which the immigrants compare the two worlds an collocates themselves between the two cultures, the function of code-switching, the linguistic expression of ‘agency’ (Giddens 1979 and the use of deictics.

    Full Text Available This essay analyses the literary, ethical and religious principles on the basis of which four eighteenth-century Dante commentators chose to extrapolate and mention excerpts from Orlando Furioso. Francesco Laino, Giovannantonio Volpi, Pompeo Venturi and Baldassarre Lombardi contributed to sanction the editorial and didactic fortune of the Ariostean poem, without excluding any extreme forms of preventative censorship. Their exercises in rewriting and textual/interpretative criticism had a profound and scarcely examined influence both on the construction of the nineteenth-century national canon and the revision of the traditional tools of linguistic/literary analysis, such as the Crusca vocabulary which Vincenzo Monti and Giacomo Leopardi discussed afresh.

    2008-03-01

    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.

  20. AV e attività di eccellenza. Nuove opportunità localizzative nel sistema Roma-Napoli

    , 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.

    policies refer to individuation of urban zones specifically dedicated to tourist bus parking also in tourist cities. This underlines a lack of integrated planning and policies aimed at optimizing urban supply to reduce the congestion caused by tourist flows. Parking facilities should be built in order to avoid urban congestion problem due to tourist charge. These specific parking areas should be located outside the inner city whose connection should be ensured though: –ecologic tourist shuttle also equipped to give information about visit modalities and tourist attractions; –bike sharing or other sustainable transport modality allowing flexibility in scheduling visit especially for some specific tourist users (i.e. young people, families, students, etc.; –taxi sharing allowing to reach rapidly central zones especially for business tourist; –design of equipped pedestrian and cycling routes to get information or other kind of support services aimed to optimize the visit. Special incentives could be provided for some specific tourist typologies (i.e. students, seniors, families, young people.L’attività turistica genera impatti diretti sulla mobilità urbana in termini di incremento sia dei livelli di inquinamento sia della congestione urbana. Le politiche orientate alla gestione della mobilità turistica in ambito urbano fanno riferimento soprattutto ad interventi restrittivi per ridurre l’accesso e il transito dei bus turistici nei centri storici. Più raramente tali interventi si ispirano ad un disegno maggiormente coordinato di gestione della mobilità turistica integrato a funzioni di accoglienza ed orientamento dei flussi di visitatori in transito nelle città. La proposta di realizzare una rete urbana per l’offerta di sosta turistica integrata costituisce l’obiettivo del lavoro presentato in questo articolo. In Italia le indicazioni relative alla mobilità urbana sono contenute all’interno di specifici piani che stabiliscono le regole per il

    The most important aspects of environmental geology, related to the urban syatems are analysed in this paper; the term urban system is here preferred to urban environment, since the second one refers to a part of a complex system, that comprises social, economic, etc. environments. All the possible environmental impacts have been described to evaluate how the urban system is affected by the environmental geological components. They are subdivided into urban impacts on the environment and environmental impacts on the cities. The environmental changes induced by: quarries, natural surfaces waterproofing, drained marshes, subways for transportation networks, bridges and gully-holes, topography changes, natural hollows filling up and ground piles, loss of the natural conditions for river beds, loss of soils, falls in piezometry and connected subsistence phenomena, are classified into the firdt type of impacts, also defined as anthropic risks. The pollution of soils, surface waters (marine and fluvial), groundwater and the impact of watse management and their restorage were also dealth with. The geological risks have also been analyzed as pressure factors from the environmenton the cities. They are generally interrelated and in some cases added up. The main instruments to help monitor and manage the environment are also described. They are monitoring networks that constitute a part of the Informative Environmental Systems. A great relevance is given to the indicators and indexes of the environmental quality, either for the measurement of the quality of life that for the measurement of environmental sustainability of cities. The scientific use of such indicators and indexes is presently a subject of debate world-wide. The authors consider is correct to delineate concise indexes, obtained from state indicators for the quality of life. They are represented by the umber of days/per year in which a service was suspended, or the environment didn`t present the characteristics requested by law. On the contrary it is possible to definite concise environmental indexes for environmental sustainable cities. This because just a few indicators cannot provide a satisfactorily scientific view of the complex environments in the cities. Furthermore the matter is regulated by law, which envisages several state indicators, according to the present environmental characteristics of a country. Finally the design of an Urban Informative System architecture is outlined.

The authors have analysed the considered by us elements V, Ti, Mn, Al and Si, using the instrumental neutron activation analysis. The vanadium because is presented in the oil in higher concentrations in comparison with the other elements and so as an element which characterizes the emissions, while Ti, Mn, Al and Si, due to their terrestrial origin, are useful to put in evidence the contribution due to the lithological component. From the obtained data and in agreement with the theoretical estimations according to the atmospheric fall out, the authors convinced that during the operating time of the oil power plants of Civitavecchia, one can not observe appreciable variations of vanadium in some soils of Tolfa mountains. The obtained data can be useful in the other future studies which will aim to evaluate the entity of the contribution of such elements coming from the oil power plants of Civitavecchia.

    The variety of biomaterials applications in medical devices for substitution or functional integration of organs and tissues has remarkably grown. This has allowed an increased survival of patients affected by traumatic or pathologic events. Biomaterials growing variety and improvement were remarkable and constant over the last twenty years; this fact yielded important clinical effects in every medical area, especially in orthopaedics, cardiovascular surgery and dentistry. Performances of medical materials are evaluated according to their bio functionality and biocompatibility. These concepts are strongly connected: bio functionality refers to devices physical and mechanical properties which allow to perform a specific function. Several transformation methods and different processing technologies allow to obtain products having different physico-chemical and mechanical properties. Among them, chemical and physical stability, biocompatibility, possibility to undergo sterilisation process, control of gases and moisture permeability, control of biodegradation products, wear and fatigue resistance and toughness are the most relevant. Most of research efforts are devoted to improve reliability and last of biomaterials already used thanks to their bio functionality and biocompatibility. Expected developments of medial devices are associated with the design of bio artificial organs, where biomaterials act as a scaffold for the three-dimensional cells growth. [Italian] Il numero delle applicazioni dei biomateriali in dispositivi medici che sostituiscono od integrino dal punto di vista funzionale organi o tessuti e' cresciuto notevolmente. Questo ha portato ad un aumento della sopravvivenza dei pazienti colpiti da eventi patologici o traumatici. La crescita ed il perfezionamento dei biomateriali e' stata, infatti, nell'ultimo ventennio considerevole e costante ed ha avuto importanti ricadute cliniche in tutte le discipline mediche ed in particolare in ortopedia, in chirurgia cardiovascolare ed in odontoiatria. Le prestazioni dei materiali utilizzati in campo medico sono valutate analizzandone le caratteristiche di biofunzionalita' e biocompatibilita'. Tali concetti sono strettamente collegati: la biofunzionalita' si riferice alle proprieta' che un dispositivo deve avere per realizzare una certa funzione dal punto di vista fisico e meccanico, mentre la biocompatibilita' alla capacita' del dispositivo di continuare a svolgere quella determinata funzione, nel o sul corpo, durante tutta la vita utile dell'impianto che puo' anche essere permanente. I numerosi metodi di trasformazione e le differenti tecniche di lavorazione dei materiali polimerici consentono di ottenere dei prodotti che soddisfano diverse proprieta' fisico-chimiche e meccaniche, come la stabilita' chimica e fisica, la biocompatibilita', la possibilita' di subire processi di sterilizzazione, il controllo della permeabilita' a gas e umidita', il controllo dei processi di biodegradazione, la resistenza all'usura ed ai carichi ciclici, la durezza. Gran parte della ricerca sara' mirata al miglioramento dell'affidabilita' e della durata dei biomateriali gia' impiegati attualmente grazie alle loro caratteristiche di biofunzionalita' e biocompatibilita'. Gli sviluppi piu' attesi nel campo dei dispositivi medici sono relativi alla produzione di organi bioartificiali, in cui i biomateriali facciano da supporto per la crescita cellulare tridimensionale, utilizzando le competenze dell'ingegneria tissutale.

    2009-01-01

    Full Text Available Spatial Metaphors for Self-knowledge in the dialogues of H.S Skovoroda. Patristic Sources In this paper the Author analyzes some spatial metaphors informing H.S. Skovoroda’s representation of self-knowledge as a dynamic process. Knowledge of the true self – which is one of the recurring themes in the Ukrainian philosopher’s oeuvre – is often portrayed as tension between open (e.g. streets, markets, the sky, the planets… and closed spaces (e.g. the house, the room, with the ‘home’ being a symbol for the soul. As man seeking communion with God has to abandon what lies outside his inner self, the authentic gnoseological process is represented as an introverted movement through symbolic space. Broadly speaking, this very opposition harks back to Philo of Alexandria and Patristic thought, whose anti-physicist stance shaped their rejection of the phenomenological world as an ‘interior vs. exterior’ contrast. Furthermore, the broader biblical context in which those spatial terms appear is also taken into account, while demonstrating Skovoroda’s partial dependence on Patristic models. The fi nal part of the paper argues that the scheme underlying Neo-platonic emanation – which is itself to be considered as an oscillation between unity and dispersion – appears to be a symbolic model for Skovoroda’s spatial representation of self-knowledge.

METHODS: Literature search was based on MEDLINE, on Iowa-IDIS and Drugdex databases (1966-Dec 2004. Analysis included 12 randomized controlled trials (3.778 patients, 8 for olanzapine (2.559 patients and 4 for aripiprazole (1.219 patients. RCT inclusion criteria were: a Patients affected by schizophrenia; b Randomized assignment to olanzapine or aripiprazole treatment group; c Number of patients included in the treatment group higher than 100; d Drop-out frequency evaluation between 4th and 26th weeks of follow-up. RESULTS: The rate of treatment discontinuation was greater for aripiprazole than for olanzapine (42,2% vs. 31,6% respectively. The comparison between drop-out percentages is statistically significant (p<0,001. CONCLUSIONS: The incidence of drop-outs was better controlled in the olanzapine group of studies than in the aripiprazole group of studies.

    It is commonly, although not universally, accepted that most intra and interspecific genome sequence variations are more or less neutral, whereas a large fraction of organism-level phenotypic variations are adaptive. Gene expression levels are molecular phenotypes that bridge the gap between genotypes and corresponding organism-level phenotypes. Yet, it is unknown whether natural variations in gene expression levels are mostly neutral or adaptive. Here we address this fundamental question by genome-wide profiling and comparison of gene expression levels in nine yeast strains belonging to three closely related Saccharomyces species and originating from five different ecological environments. We find that the transcriptome-based clustering of the nine strains approximates the genome sequence-based phylogeny irrespective of their ecological environments. Remarkably, only ∼0.5% of genes exhibit similar expression levels among strains from a common ecological environment, no greater than that among strains with comparable phylogenetic relationships but different environments. These and other observations strongly suggest that most intra and interspecific variations in yeast gene expression levels result from the accumulation of random mutations rather than environmental adaptations. This finding has profound implications for understanding the driving force of gene expression evolution, genetic basis of phenotypic adaptation, and general role of stochasticity in evolution. © The Author 2017.

    Full Text Available In the era of hand-press printing, variations among the copies of a single edition was the norm rather than the exception. Indeed, no single copy would ever be identical to another, but rather each one would be unique. These differences were due not only to the marks and features that each item acquired after leaving the printing shop, according to the hands through which it passed, but also to the features that accumulated during the printing process itself. These characteristics could be of two kinds: conscious variants, either when the printer made stop-press corrections to typesetting errors or other mistakes that had been missed during proof reading or to add later corrections by the editor or author; unconscious variants when they were the result of unnoticed mistakes made by the printer himself. In the preparation of her dissertation for a degree in Bibliography, the author made a census of the surviving examples of Italian-German lexicons recorded in Italian incunabula production and described them. The conscious and unconscious printing errors collated are analyzed in this paper.

    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

    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.

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

  5. Waterway e sviluppo del territorio: nuova mobilità e turismo sostenibile

    Directory of Open Access Journals (Sweden)

    2010-10-01

    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.

    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.

    The traditional systems of water depuration are often responsible of undesirable ecological problems. In fact, the oxidation of pollutants due to standard sewage treatments may induce the overproduction of nutrients. Therefore the wastewater effluents may cause the eutrofication of receiving water bodies. To avoid aftereffects on life conditions of aquatic organisms, nutrient retention based on microphytes and macrophytes abilities is often utilized after traditional sewage treatments. As a matter of fact, in many countries the phytodepuration basins or artificial wetlands have been designed to receive primary and/or secondary wastewater effluents or are used directly for depuration of wastewater of small towns and/or effluents of small industries. In this report they take into account the main biological features of the common techniques of natural water depuration.

The present article illustrates the principal results of the fourth survey that relates to 1962 and is now in course of publication. The analysis is confined to data regarding to labour cost shown as borne by the enterprises, and does not take account of studies made by ECSI of workers’ incomes in various countries. In particular, the author considers the data on the cost of labour in Italy. The data is brought up to date for 1963 and 1964 to show the changes that have taken place in Italy’s position with respect to previous years. While in the surveys tom 1959 and 1960 Italy was shown to have the lowest labour cost among Common Market countries, it now comes in first in the classification and has in almost every case registered a labour cost very near to the highest figure.JEL: E24, J30

    The variety of biomaterials applications in medical devices for substitution or functional integration of organs and tissues has remarkably grown. This has allowed an increased survival of patients affected by traumatic or pathologic events. Biomaterials growing variety and improvement were remarkable and constant over the last twenty years; this fact yielded important clinical effects in every medical area, especially in orthopaedics, cardiovascular surgery and dentistry. Performances of medical materials are evaluated according to their bio functionality and biocompatibility. These concepts are strongly connected: bio functionality refers to devices physical and mechanical properties which allow to perform a specific function. Several transformation methods and different processing technologies allow to obtain products having different physico-chemical and mechanical properties. Among them, chemical and physical stability, biocompatibility, possibility to undergo sterilisation process, control of gases and moisture permeability, control of biodegradation products, wear and fatigue resistance and toughness are the most relevant. Most of research efforts are devoted to improve reliability and last of biomaterials already used thanks to their bio functionality and biocompatibility. Expected developments of medial devices are associated with the design of bio artificial organs, where biomaterials act as a scaffold for the three-dimensional cells growth. [Italian] Il numero delle applicazioni dei biomateriali in dispositivi medici che sostituiscono od integrino dal punto di vista funzionale organi o tessuti e' cresciuto notevolmente. Questo ha portato ad un aumento della sopravvivenza dei pazienti colpiti da eventi patologici o traumatici. La crescita ed il perfezionamento dei biomateriali e' stata, infatti, nell'ultimo ventennio considerevole e costante ed ha avuto importanti ricadute cliniche in tutte le discipline mediche ed in particolare in ortopedia, in chirurgia cardiovascolare ed in odontoiatria. Le prestazioni dei materiali utilizzati in campo medico sono valutate analizzandone le caratteristiche di biofunzionalita' e biocompatibilita'. Tali concetti sono strettamente collegati: la biofunzionalita' si riferice alle proprieta' che un dispositivo deve avere per realizzare una certa funzione dal punto di vista fisico e meccanico, mentre la biocompatibilita' alla capacita' del dispositivo di continuare a svolgere quella determinata funzione, nel o sul corpo, durante tutta la vita utile dell'impianto che puo' anche essere permanente. I numerosi metodi di trasformazione e le differenti tecniche di lavorazione dei materiali polimerici consentono di ottenere dei prodotti che soddisfano diverse proprieta' fisico-chimiche e meccaniche, come la stabilita' chimica e fisica, la biocompatibilita', la possibilita' di subire processi di sterilizzazione, il controllo della permeabilita' a gas e umidita', il controllo dei processi di biodegradazione, la resistenza all'usura ed ai carichi ciclici, la durezza. Gran parte della ricerca sara' mirata al miglioramento dell'affidabilita' e della durata dei biomateriali gia' impiegati attualmente grazie alle loro caratteristiche di biofunzionalita' e biocompatibilita'. Gli sviluppi piu' attesi nel campo dei dispositivi medici sono relativi alla produzione di organi bioartificiali, in cui i biomateriali facciano da supporto per la crescita cellulare tridimensionale, utilizzando le competenze dell'ingegneria tissutale.

Rimane il grosso vantaggio rappresentato dalla comunicazione diretta, quasi in tempo reale, se le persone sono in quel momento collegate al programma, quindi sono in grado di replicare. Diventa quindi il possibile veicolo e motore di movimenti di opinione, di gruppi spontanei di persone, di emozioni che possono diventare “oceaniche”, come quando, in uno stadio gremito, tutti si muovono all’unisono sotto il segno della ola. Vengono così soddisfatte la partecipazione e la reciprocità nel bisogno di relazione, e viene soddisfatto il bisogno delle persone di narrazione, ovvero il bisogno di raccontare con leggerezza ad un possibile interlocutore, o ad una platea, la propria storia in frammenti, attraverso commenti puntuali, espressioni di intento, canzoni e immagini. La narrazione, oggi, è fenomeno sempre più raro, grazie al crollo del valore aggiunto rappresentato dall’esperienza, e si è trasformata in storytelling.

  2. Dalla contabilità finanziaria ai risultati economico-patrimoniali nei musei pubblici: una proposta metodologica / From financial accounting to financial results in pubblic museums: a methodological framework

    Full Text Available Secondo il New Public Management, tutti i settori della pubblica amministrazione devono essere in grado di misurare le loro performance secondo una visione multi-dimensionale. I musei pubblici – statali, civici, universitari, ecc. – sono spesso una parte di una pubblica amministrazione, perciò i loro dati contabili e di bilancio sono “confusi” con quelli dell’ente proprietario. Questo produce un doppio effetto negativo. Da un lato, è arduo quantificare esattamente le risorse pubbliche trasferite al museo e, dall’altro, è impossibile misurare direttamente le attività e le performance economiche, patrimoniali e finanziarie. La ricerca, di natura esplorativa, propone una metodologia per ovviare ad entrambi questi inconvenienti. Il metodo di ricerca è prevalentemente deduttivo. L’articolo, dopo un’analisi delle principali teorie e tecniche di misurazionedelle performance e la costruzione diun modello teorico, termina con un’analisi critica del modello.   According to New Public Management’s principles, all sectors of public administrationmust check their annual performance from multiple perspectives. Public museums – state, municipal, or university museums to give just a few examples – are often part of the administrative and accounting data and are therefore often mixed up with the museum’s owner. The result is doubly negative. On the one hand, it is extremely difficult to quantify the public resources transferred to the museum. On the other hand, it is impossible to keep track of its annual economic, financial and assets performance. The research is exploratory and suggests a methodology attempting to solve both problems. The research method is mainly deductive. The paper begins with an analysis of the mainstream theories and techniques for performance measurement, then it proposes a theoretical model and finally a critical analysis of that model.

    LIBS (Laser induced breakdown spectroscopy) is a new spectroscopic technique suitable to the use in the analysis of samples of environmental interest, such as soils and rocks, and of industrial interest, such as alloys. Results dealing with the application of the technique to heterogeneous soil samples certified by Ispra Joint Research Centre in the contest of heavy metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn) with an agronomical interest are presented in this report. In the LIBS technique, a high power laser beam is focused onto the sample in order to generate a small volume of plasma at its surface. Emissions from single atomic species are collected by a lens system coupled to an optical fiber bundle, dispersed on a monochromator and analyzed by an iCCD. the identification and the assignment of emission lines relevant to single atomic species allows to determine the sample elemental composition and, after calibration against reference samples, to perform quantitative analysis for a large number of species. This technique requires no sample pre-treatment, a part from eventually compacting powders by mechanical press. This is a considerable advantage with respect to traditional spectroscopic techniques, such as the ICP (Inductively Coupled Plasma) which needs sample mineralization by acid attack. Measurements performed on soil samples by means of the LIBS technique at ENEA Frascati were compared with the results obtained by ICP, which is considered a traditional technique for this kind of analysis. Results showed a general overestimation of the LIBS values with respect to the ICP ones, probably due to differences in lytologic matrix between the analyzed samples and the standard. The phenomenon is usually referred to the matrix effect, which is held responsible for the deviation from linearity between single element concentration and its row intensity. The effect is due to local plasma density variations and limit the correlation between the plasma elemental composition and the sample upon which the analytic use of LIBS technique relays. RSD % (Relative Standard Deviation) for LIBS and ICP data have been compared. LIBS values appeared systematically higher than the ICP ones. Also the correlation coefficients, calculated as the ratio between certified value and experimental one, both for LIBS and ICP, were considerably less close to one for LIBS than for ICP. In order to minimize the matrix effect, a model for correcting LIBS data by taking into account the plasma temperature experimentally determined both in the unknown and in the standard sample was introduced. Preliminary results showed a considerable improvement in the correlation coefficients for corrected LIBS data. Once the model validity is proven for different elements used in the plasma temperature determination, which is possible once known all the parameters of Boltzmann equation for experimental intensity spectral line, it is quite general and can be applied on all the samples and for all the elements. [Italian] Il LIBS (Laser induced breakdown spectroscopy) e' una tecnica spettroscopica sperimentale che trova applicazione nell'analisi di campioni di interesse ambientale, quali suoli e rocce, ed industriali, come leghe metalliche. In questo rapporto sono presentati i risultati dell'applicazione della tecnica a campioni eterogenei di suoli certificati dal Joint Research Centre di Ispra (Varese) per la valutazione delle concentrazioni di metalli pesanti di interesse agronomico (Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn). Nella tecnica LIBS, un impulso laser d'alta potenza e' focalizzato sul campione in modo da provocare sulla superficie dello stesso un piccolo volume di plasma. Le emissioni delle singole specie atomiche sono raccolte da fibra ottica e analizzate da un monocromatore e da un analizzatore ottico (iCCD). Il riconoscimento e l'assegnazione delle emissioni spettrali corrispondenti ai singoli elementi atomici permette di riconoscere la composizione elementale del campione e, mediante l'utilizzo di emissioni di campioni a concentrazione nota, di risalire alle concentrazioni delle singole specie del campione. Il grande vantaggio di questa tecnica e' che non e' richiesto alcun trattamento del campione (come invece e' il caso in tecniche spettroscopiche tradizionali quale l'ICP, Inductively Coupled Plasma, che richiede la mineralizzazione del campione tramite attacco acido con acqua regia), se non il semplice compattamento tramite pressa meccanica. I risultati ottenuti dall'applicazione della tecnica LIBS al centro ricerche ENEA di Frascati sui campioni di suolo sono stati analizzati per confronto con i risultati ottenuti con una tecnica tradizionale quale l'ICP. Si osserva una sistematica sovrastima del valore LIBS rispetto a quello ICP, probabilmente imputabile alle differenze di matrice litologiche tra i campioni analizzati e quelli usati come riferimento.

The exhibition lasts one year, and consequently becomes a new “event”, in connection with the contemporary dionysiac pompé: the works of art acquire a new meaning, connoting the Lagides as refined collectors, and are part of a cultural and political program, probably organized by the Museum scholars. The exhibition, indeed, is marked by an encyclopaedical purpose: on one hand it seems to be the ephemeral equivalent of the  Museum and of the zoo promoted  by Ptolemy I, on the other it takes part in the cultural construction of the Ptolemean family, being almost its dynastic monument.

    Full Text Available This essay deals with the birth of a practical documentation relating to the current managing of direct taxation in several communes of the principality of Savoy-Achaea, in Piedmont (particularly Moncalieri, Pinerolo and Turin, between the end of the 13th century and the first half of the 14th century. The increase in the tax burden of the prince on communities stimulated the development of the structure and contents of municipal accounting records. On the one hand there was a gradual tendency for writing the majority of the collection and audit operations carried out by municipal officers. On the other hand, the accounting records were organized as a coherent system of thematic registers, tied to one another by functional links and intertextuality. After 1330 a municipal finance crisis caused an increase of political functions attributed to accounting records, as an instrument of control over the fiscal behaviour of citizens; an effect of this situation was the production of registers dedicated to lists of tax evaders.

  9. Musica e metropoli. I flussi urbani del funk carioca tra i morro, l’asfalto e il largo di Rio de Janeiro - Music and metropolis. The urban flows of carioca funk among the morro, the asfalto and the largo in Rio de Janeiro

    Full Text Available Since the 70’s, American funk and Miami Bass music genres have been incorporated into the soundscape of Rio de Janeiro. They crossed national boundaries and reached marginal areas of the metropolis – which I call “morro” (hills hosting the favelas – where they turned funk carioca. Along the 80’s and 90’s, this new Brazilian music genre has been subject to conflicting processes of commercialization and discrimination. Funk carioca has spread all the way to the city and in the mass media, but at the same time it has been stigmatized as a violent and dangerous borderline culture: it was reaching and endangering the “asphalt” – the way Carioca people refer to the flat areas inhabited by middle and upper social classes. From 2000 on, some social movements claimed acknowledgement of the music genre as a positive carioca feature and cultural expression, organizing funk parties (bailes funk in emblematic public places, such as Largo da Carioca. Considering funk carioca as a fluid which crossed international and national boundaries, this paper’s aim is to analyze the “urban flows” it has been drawing in the social and urban texture of Rio. It puts at stake the historical trajectory funk carioca outlined through the milieus of morro, asfalto and largo. Hence, the ethnographic and comparative description of bailes funk suggests that funk carioca has not undergone a straightforward trajectory, but a synchronic, fluid and dispersive diffusion: it finally reached the largo, but it is still present both on morro and asfalto, where bailes funk differ but still coexist.

    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

    Full Text Available Il presente studio è parte di una ricerca promossa dal Centro Studi Faunistica dei Vertebrati della SISN. Il progetto è iniziato nel 1999 ed è ancora in corso. L'area di studio (161 Km² si trova nella zona collinare dell'Oltrepò ed è compresa, sul reticolato cartografico UTM, tra i Km 4972 e 4960 Nord, e i Km 1505 e 1520 Est. Lo scopo principale della ricerca era di valutare l'importanza delle caratteristiche ambientali nella scelta e selezione dell'habitat del tasso, relativamente al posizionamento delle tane. Nel periodo di studio sono stati rilevati i dati ambientali su 23 punti tana (pt e 28 punti casuali (pc, successivamente inseriti in un GIS dal quale, attraverso l'analisi di carte tematiche digitalizzate, sono state ricavate diverse altre informazioni (uso del suolo, geologia, litologia, sviluppo dei corsi d'acqua, delle strade e dei centri abitati considerando aree di raggio 300 e 600 m intorno ai pt e pc. I dati raccolti sono stati oggetto d'analisi statistiche con test di confronto fra pt e pc, indice di selezione di Manly e tecniche classificatorie multivariate (regressione logistica. Le tane di tasso sono prevalentemente scavate in luoghi protetti, caratterizzati da un'elevata copertura. La differenza tra gli ambienti nei quali sono situate le tane e quelli relativi ai punti casuali si è rivelata estremamente significativa (Χ²=18.20; d.f.=1; p<0.001.

    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.

    Conclusioni: l’identificazione di isolati ambientali si

    Full Text Available Il patrimonio cinematografi co dell’Istituto Nazionale Luce raccoglie alcune centinaia di ore di fi lmati che riguardano la storia delle mostre e dei musei del ‘900 in Italia e non solo. Sin dalla sua nascita, nel 1925, il LUCE (L’Unione Cinematografi ca Educativa inviò i suoi operatori a documentare musei, gallerie e mostre, specialmente in occasione di visite ufficiali dei sovrani e di esponenti del regime fascista. Cinegiornali e documentari didattici sono visibili on-line sul sito dell’Archivio, e parzialmente anche sul canale dedicato di YouTube. Il contributo traccia una prima ricognizione di un vasto panorama di materiali documentari e informativi, dando conto dell’uso del mezzo fi lmico per documentare le esposizioni temporanee e i musei. L’importanza del materiale del LUCE, che a partire dal 1931 diventa anche sonoro, offre uno spaccato ancora poco conosciuto di questa forma di documentazione in relazione al coevo dibattito sui musei, tra propaganda e uso pedagogico dell’immagine. Vengono esaminate modalità e strategie di presentazione visive e testuali distinguendo tra gli i musei di archeologia, arte antica, arte moderna e contemporanea, considerando alcuni casi specifi ci di esposizioni temporanee come la Biennale di Venezia e la Quadriennale di Roma. La conclusione è dedicata ad una rifl essione sui viaggi di Adolf Hitler in Italia in rapporto al patrimonio artistico e architettonico. The film heritage of the National Institute Luce collects several hundred hours of footage covering the history of the exhibitions and museums of the ‘900 in Italy and beyond. Since its inception in 1925, the LUCE (The Union Educational Film sent his workers to document museums, galleries and exhibitions, especially on the occasion of offi cial visits of kings and members of the fascist regime. Newsreels and educational documentaries and that for some years on-line are also visible on the Archive audiovisual database, and partly also on the dedicated YouTube channel. The paper draws a fi rst reconnaissance of a vast landscape of documentary materials and informative, giving regard to the use of the medium of fi lm to document the temporary exhibitions and museums. The importance of the LUCE’s material, which in 1931 also becomes sound, offers a glimpse still little known of this form of documentation in relation to the contemporary debate on museums, including propaganda and pedagogical use of the image. Ways visual and textual presentation strategies are examined distinguishing among the museums of archeology, ancient art, modern and contemporary art, considering some specifi c cases of temporary exhibitions like the Venice Biennale and the Rome Quadrenniale. The conclusion is dedicated to a refl ection on Adolf Hitler travels in Italy in relation to the artistic and architectural heritage.

  18. L’importanza della “fiducia” nei rapporti tra i membri della Soka Gakkai in Italia - The importance of “trust” in the relationships among the members of Soka Gakkai in Italy

    Directory of Open Access Journals (Sweden)

    Maria Giulia Pezzi

    2014-06-01

    Full Text Available This article considers the analysis of trust issues among Buddhist Sect Soka Gakkai members in the Italian town of Monza. Soka Gakkai is a religious organization which bases its doctrine on the teachings of the Buddhist monk Nichiren Daishonin, who lived in the thirteenth century in Japan, and which has rapidly grown in Italy since the late 1970s. The organization is constituted by official members and neophytes, who interact on a daily basis in a familiar environment, with a high degree of intimacy and informality. Although one cannot account the existence of a proper “clergy”, Soka Gakkai is constituted through a strict pyramidal organization, which influences the ways in which members interact. Trust among members can be considered as a core issue, and is seen as composed by three elements – instrumental, moral and emotive. Moreover, to analyze the attitudes of Soka Gakkai members toward themselves, but also towards fellow members, Soka Gakkai, its leaders and the religious doctrine, it is useful to use the concepts of “trust in trust” and “distrust in distrust”, starting from the assumption that Soka Gakkai provides the devotees with a definition of self to which the member is required to conform, but that can also be manipulated in circumstances affected by uncertainty, as the conversion to a new religion can be.

Diversity values exhibit no apparent correlation with a number of environmental and biocoenotic parameters of non-anthropic origin - i.e.: district age, height on sea level, latitude, biocoenotic (Renkonen's and faunistic (Faith's affinities. Conversely, a clearly significant, negative correlation with landscape anthropization was shown, revealing the importance of man's impact in shaping functional connections in the terrestrial communities of studied region.

Should Article 2(2(a of Council Directive 2000/78/EC of 27 November 2000 establishing a general framework for equal treatment in employment and occupation be interpreted as meaning that the prohibition on wearing, as a female Muslim, a headscarf at the workplace does not constitute direct discrimination where the employer’s rule prohibits all employees from wearing outward signs of political, philosophical and religious beliefs at the workplace? (case C-157/15. Must Article 4(1 of the same Council Directive be interpreted as meaning that the wish of a customer of an information technology consulting company no longer to have the information technology services of that company provided by an employee, a design engineer, wearing an Islamic headscarf, is a genuine and determining occupational requirement, by reason of the nature of the particular occupational activities concerned or of the context in which they are carried out?

    Full Text Available L’emigrazione italiana verso il continente americano ha rappresentato un fenomeno dell’età contemporanea di ingenti dimensioni: la grandissima comunità italiana negli Stati Uniti è stata oggetto di numerosi approfondimenti storiografici, letterari, cinematografici, oltre a costituire ormai parte integrante della storia, dell’economia e, in genere, della società americana. Tuttavia, una parte degli emigranti scelse differenti mete: l’America Latina, il Canada. Questo articolo si sofferma sulla nascita e l’integrazione nell’economia canadese della prima comunità italiana −a inizio ‘900− che avrebbe costituito la base per flussi migratori successivi più cospicui, nel secondo dopoguerra. La ricerca, di taglio storico-economico, mette in luce soprattutto l’aspetto finanziario della vicenda, e presenta un’analisi dettagliata –basata sulla documentazione del Servizio Emigrati dell’Archivio Storico del Banco di Napoli– del servizio di raccolta e spedizione in patria delle rimesse degli emigrati da parte delle banche canadesi incaricate: un fenomeno che andò incrementandosi con la crescita della comunità italo-canadese. The Italian emigration to America was a phenomenon of huge dimensions of the contemporary age: the large Italian community in the US has been the subject of numerous insights historiographical, literary, film, besides being now an integral part of the history, of the economy and, in general, of the American society. However, part of the emigrants chose different destinations: Latin America, Canada. This article focuses on the birth and the integration in the Canadian economy of the first Italian community −at the beginning of '900− which would have formed the basis for increased levels of migratory flows, after World War II. The research, historical-economic cutting, highlights especially the financial aspect of the story, and presents a detailed analysis −based on the documentation of the Migrant Service of the Historical Archive of the Banco di Napoli− about the collection and delivery at home of remittances from the Canadian banks responsible: a phenomenon that incremented with the growth of the Italian-Canadian community.

  7. The corbiculate bees arose from New World oil-collecting bees: implications for the origin of pollen baskets.

    Science.gov (United States)

    Martins, Aline C; Melo, Gabriel A R; Renner, Susanne S

    2014-11-01

    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.

    Directory of Open Access Journals (Sweden)

    Brogiolo, Gian Pietro

    2002-12-01

    Full Text Available The author makes a summary on the situation of Building Archaeology in Italy from the 1990s onwards, when the creation of the journal “Archeologia dell’architettura” and several Congresses made it possible for different groups of investigators to share their strategies and experience, both regarding stratigraphic readings and their relationship to restoration and the study of buildings techniques, dimensional chronology and archaeometry. A key argument in this debate has been the application of this set of methods to architectural restoration, and experimentation on the static equilibrium sequence, degradation and wall coating as crucial instruments in a correct restoration process. This debate has given lesser focus to the main goal of the archaeologist: to obtain historical information from stratigraphic reconstructions, for which becomes in turn necessary to prepare repertoires and undertake extensive studies, relate archaeology to agrarian structures and landscape transformations as well as with social and economic structures. Archaeologists must work on this issue on the following years, without leaving aside the intimate relationship established with architectural restoration, to preserve the building patrimony in a context which should promote cultural multicentralism, the exchange of ideas and a recovery of civil society.Il contributo delinea un bilancio dell'Archeologia dell'architettura in Italia a partire dalla metà degli anni '90 del XX secolo, quando alcuni convegni e la neonata rivista "Archeologia dell'Architettura", misero a confronto le esperienze maturate in più centri di ricerca, che riguardavano non solo l’analisi stratigrafica delle murature il suo rapporto con il Restauro, ma anche allo studio delle tecniche costruttive, della mensiocronologia e dell’archeometria.

    Full Text Available Chi all’interno dell’Offi ce International des Musées (OIM, all’indomani della prima guerra mondiale, lavorava alla ridefi nizione del ruolo dei musei, ripensandoli come luoghi di dialogo interculturale e di incontro della società presente con il proprio passato, considerava il ruolo sociale del museo e la sua funzione conservativa come parte della stessa riforma culturale. In questo scenario l’inchiesta condotta nel 1932 dall’OIM è stata occasione di confronto tra paesi membri della Società delle Nazioni sulla fi gura di ‘restauratore di opere d’arte’. Se ne considerano i percorsi formativi, fi no ad arrivare alla regolamentazione della concorrenza, valutando aspetti metodologici, critici, etici. Le posizioni che emergono dai documenti dell’Archivio dell’OIM mostrano le intersezioni tra scelte culturali e processi storico-politici, rivelano signifi cative differenze sul ruolo attribuito alla diagnostica e alla critica dalle diverse culture nazionali. L’analisi di quanto emerge da quei documenti offre l’occasione per rifl ettere su alcuni percorsi storici che hanno costituito le radici dell’attuale cultura italiana del restauro, permette di soffermarsi sul rapporto dell’Italia con gli specifi ci percorsi della cultura internazionale. Ne emergono elementi utili a considerare da un punto di vista storico i processi di trasformazione ora in atto proprio nell’ambito della formazione dei restauratori di beni culturali. In the aftermath of WW1, those working in the Offi ce International des Musées (OIM to redefi ne the role of museums – rethinking them as intercultural dialogue and meeting places of the society with its own past – considered the social role of the museum and its conservative mission as part of the same cultural reform. In this scenario the survey conducted in 1932 by the OIM was an opportunity for discussion between members OIM of the League of Nations countries on the fi gure of ‘restorer of works of art’. Aspects such as training courses, regulation of competition were analysed, taking into account theplaces methodological, historical, critical and ethical aspects. The positions that emerge from IOM Archive documents show the intersections between cultural choices and historical-political processes, reveal signifi cant differences in the role attributed to diagnostic and criticism by different national cultures. The analysis of what emerges from these documents provides an opportunity to refl ect on some historic trails that shaped the roots of the Italian culture of restoration, allowing one to dwell on Italy’s relationship with the specifi c routes of international culture. It also gives useful elements to consider, from a historical point of view, the transformation process now in place in the training of restorers of cultural heritage.

  2. Vittimizzazione e senso di insicurezza nei confronti del crimine: un'analisi empirica sul caso italiano / Criminal victimization and people's perception of safety: an Italian research / Victimisation criminelle et sentiment d'insécurité: une recherche empirique en Italie

    Full Text Available In this paper the relationship between criminal victimization and people’s perception of safety is explored. At first sight, the connection between these phenomena seems to be obvious: victims of a crime are probably more unsafe than non victimized people. However, many studies have found that the relationship between fear and crime is more complex than expected. In the first part of the paper the mixed research results are discussed and some reasons of this heterogeneity are identified. In the second part an analysis is conducted on data from the Italian Survey on Citizens’ Safety (Indagine sulla sicurezza dei cittadini. The main findings indicate that victimization affects both feelings of safety in the streets and in one’s own home, but with different intensity. Theft and snatch victimization is associated with safety in the streets, whereas burglary victimization with the perception of safety in one’s own home. Multivariate binomial regression models show that in Italy previous victimization contributes to increase the probability of feeling unsafe both in the streets and in one’s own home, all else being equal.Le but de cet article est d'analyser la relation entre l'expérience de victimisation et le sentiment d'insécurité collective. Au premier regard, la relation entre ces deux phénomènes peut sembler évidente: le sentiment d'insécurité est peut-être plus fort chez les victimes de crime que chez ceux qui n'ont jamais été frappés par le crime. Toutefois, beaucoup d'études ont montré que la relation entre l'insécurité et le crime est plus complexe qu'on ne l'avait prévu. Dans la première partie de cet article, nous discutons les résultats contradictoires des études mentionnées plus haut et identifions quelques-un des motifs de cette hétérogénéité. Dans la deuxième partie, nous effectuons une analyse sur les données de l'enquête italienne sur la sécurité des citoyens (Indagine sulla sicurezza dei cittadini. Les résultats montrent que la victimisation subie influence aussi bien le sentiment d'insécurité éprouvé dans les rues qu'au domicile, mais ces deux perceptions ont une intensité différente. Le sentiment d'insécurité dans les rues est plus fort chez les personnes victimes d'un vol ou d'un vol à l'arachée tandis que le sentiment d'insécurité au domicile est plus répandu chez ceux qui ont subis un cambriolage. Les modèles de régression multivariés indiquent qu'en Italie la victimisation subie contribue à augmenter la probabilité d'éprouver aussi bien le sentiment d'insécurité dans les rue qu'au domicile.

    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.

  11. NEIMiner: nanomaterial environmental impact data miner.

    Science.gov (United States)

    Tang, Kaizhi; Liu, Xiong; Harper, Stacey L; Steevens, Jeffery A; Xu, Roger

    2013-01-01

    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/.

  12. Description and evaluation of a net energy intake model as a function of dietary chewing index

    DEFF Research Database (Denmark)

    Jensen, Laura Mie; Markussen, Bo; Nielsen, N. I.

    2016-01-01

    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...

  18. Organization model and formalized description of nuclear enterprise information system

    International Nuclear Information System (INIS)

    Yuan Feng; Song Yafeng; Li Xudong

    2012-01-01

    Organization model is one of the most important models of Nuclear Enterprise Information System (NEIS). Scientific and reasonable organization model is the prerequisite that NEIS has robustness and extendibility, and is also the foundation of the integration of heterogeneous system. Firstly, the paper describes the conceptual model of the NEIS on ontology chart, which provides a consistent semantic framework of organization. Then it discusses the relations between the concepts in detail. Finally, it gives the formalized description of the organization model of NEIS based on six-tuple array. (authors)

  19. Pratiche dei migranti e processi di ri-significazione dello spazio pubblico

    Directory of Open Access Journals (Sweden)

    Daniela Panariello

    2014-11-01

    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.

  20. Marketing CANDU internationally

    International Nuclear Information System (INIS)

    Langstaff, J.H.

    1980-06-01

    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.

    Dasse, Kurt A; Gellman, Barry; Kameneva, Marina V; Woolley, Joshua R; Johnson, Carl A; Gempp, Thomas; Marks, John D; Kent, Stella; Koert, Andrew; Richardson, J Scott; Franklin, Steve; Snyder, Trevor A; Wearden, Peter; Wagner, William R; Gilbert, Richard J; Borovetz, Harvey S

    2007-01-01

    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.

  2. New host records of Aglaomelissa duckei and a compilation of host associations of Ericrocidini bees (Hymenoptera: Apidae)

    OpenAIRE

    2009-01-01

    For the first time, confirmed host records are reported for the monotypic Ericrocidini genus Aglaomelissa Snelling & Brooks, 1985. Aglaomelissa duckei (Friese, 1906) emerged from trap-nests of Centris (Heterocentris) analis (Fabricius, 1804) and C. (Heterocentris) terminata Smith, 1874 from two sites in the Brazilian Amazonian region. The parasitism ratio caused by A. duckei was high, varying from 80 to 100% of the brood cells in a single trap-nest. Also, a compilation of the known host r...

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

    Directory of Open Access Journals (Sweden)

    Kiran Lata

    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.
