Neuropeptide glutamic acid-isoleucine (NEI)-induced paradoxical sleep in rats.

Science.gov (United States)

Fujimoto, Moe; Fukuda, Satoru; Sakamoto, Hidetoshi; Takata, Junko; Sawamura, Shigehito

2017-01-01

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

Science.gov (United States)

Moolla, Nabiela; Goosens, Vivianne J; Kana, Bavesh D; Gordhan, Bhavna G

2014-01-01

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.

Audiovisivi per línsegnamento e nuove tecnologie nelle classi 2.0 della regione Emilia-Romagna

Directory of Open Access Journals (Sweden)

Laura Corazza

2015-01-01

Full Text Available I bambini e i ragazzi nel nuovo millennio sono forse più avvezzi alla visione di un film o di una trasmissione televisiva che non alla lettura di un libro. Quello che è certo, è che sono sottoposti a un bombardamento mediatico senza precedenti grazie a canali televisivi specializzati nella produzione di programmi per l’infanzia e l’adolescenza, alla Rete Internet e ai dispositivi mobili di ultima generazione. E a scuola? Come cambia la didattica? Al laboratorio Mela abbiamo documentato con un video l’avvio della prima esperienza delle Cl@ssi 2.0 in Emilia-Romagna nelle scuole secondarie inferiori. Alla fine dei 3 anni di sperimentazione, durante i quali gli insegnanti hanno utilizzato LIM, computer in classe e Moodle per l’insegnamento a distanza, abbiamo invece cercato di capire, con un questionario, come e quanto vengano utilizzati i video per la didattica. Ne sono seguite alcune riflessioni.

Il rumore elettrico Dalla fisica alla progettazione

CERN Document Server

Pallottino, Giovanni Vittorio

2011-01-01

L’opera fornisce una trattazione chiara, agile ed essenziale, ma completa, del rumore elettrico, argomento considerato generalmente oscuro e specialistico. Molto più breve (circa 275mila battute) dei testi attualmente disponibili. Il contenuto copre gli aspetti essenziali della matematica e della fisica del rumore (termico, shot. 1/f, …), e della sua rappresentazione nei circuiti. Discute quindi il rumore nei dispositivi passivi e attivi, e introduce i criteri di progettazione a basso rumore. Affronta infine brevemente questioni quali l’estrazione del segnale dal rumore e gli impieghi utili del rumore. L’attenzione è generalmente rivolta alla strumentazione fisica a bassa frequenza, in relazione alla pluridecennale esperienza specifica dell’autore. Si tratta di una estensione delle dispense, utilizzate per anni, di un corso universitario. Pertanto la trattazione è fortemente didattica, con particolare attenzione a rimuovere ambiguità e incertezze, discutendo il materiale in termini fisici intuit...

Małgorzata Berezowska

2017-07-01

Full Text Available L’uso dei prefissi e dei suffissi superlativi, oltre alla loro funzione di base in quanto indicatori delle dimensioni dell’oggetto descritto o dell’intensità delle sue proprietà, può servire a esprimere l’atteggiamento del parlante nei confronti della realtà extralinguistica. Questi elementi morfologici svolgono non solo la loro funzione di base, ma possono essere utilizzati nella loro funzione secondaria: quella di trasmettere le emozioni dell’autore dell’enunciato. Il materiale linguistico analizzato nell’articolo, tratto dai forum di discussione, riflette le tendenze tipiche dello stile femminile e del linguaggio giovanile.

Nuclear Energy Institute (NEI) summary

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

Learning Analytics: opportunities for schools

Directory of Open Access Journals (Sweden)

Giovanni Fulantelli

2014-12-01

Full Text Available La valutazione delle esperienze di apprendimento che avvengono in ambienti in cui le interazioni sono mediate dalle tecnologie è una sfida ardua che deve essere affrontata con approcci adeguati. Le tecniche di Learning Analytics si sono sviluppate recentemente con l’obiettivo di fornire gli strumenti necessari per ottimizzare le esperienze di apprendimento. Queste tecniche supportano i docenti nel prendere tempestivamente quelle decisioni che rendono il processo didattico più efficace, permettendo di intervenire sull’intero processo o sui singoli studenti in modo personalizzato. Sebbene le tecniche di Learning Analytics si siano sviluppate principalmente nei contesti di alta formazione online, questo articolo mette in evidenza come l’impiego di tali tecniche può portare benefici anche nei contesti scolastici. Di fatto, in questi contesti, le tecnologie sono sempre più utilizzate per supportare le esperienze di apprendimento formali e informali, come quelle basate su dispositivi mobili, serious game e social network, e i dati generati sono sempre più numerosi, richiedendo nuovi approcci di analisi che traggono vantaggio dall’impiego delle tecniche di Learning Analytics.

Grado di cheratinizzazione dell'epitelio ruminale e valutazione dello stato corporeo in ovini tenuti su pascoli di Brachypodium rupestre

Directory of Open Access Journals (Sweden)

Paola Scocco

2013-06-01

Full Text Available L'articolo valuta e mette in correlazione i cambiamenti del grado di cheratinizzazione della mucosa ruminale con lo stato corporeo di ovini tenuti a pascolare per 20 giorni in un'area ad elevata copertura di paléo rupestre (Brachypodium rupestre. Il pascolo degli ovini in queste aree riduce il rischio di incendi boschivi. Tuttavia, l'assunzione di Brachypodium rupestre protratta per lunghi periodi può compromettere la salute generale degli animali. Lo scopo di questo studio è di determinare il periodo massimo di permanenza degli animali in queste aree. Ovini mantenuti su un pascolo semi-mesofilo sono stati utilizzati come gruppo di controllo. Nei giorni 1, 10 e 20 della sperimentazione, 5 animali di ogni gruppo sono stati sacrificati per la valutazione delle modificazioni del grado di cheratinizzazione dell'epitelio dell'atrio e del sacco ventrale del rumine. La valutazione dello stato corporeo, o body condition score (BCS, e il peso vivo (PV sono stati monitorati su altri 10 soggetti per gruppo. Il gruppo di controllo ha mostrato piccole variazioni del grado di cheratinizzazione del rumine che non hanno inciso negativamente sul BCS o sul PV. Il gruppo sperimentale ha mostrato un significativo incremento del grado di cheratinizzazione, già entro i primi dieci giorni, che ha portato ad un graduale abbassamento del BCS e ad un calo di peso tra il decimo e il ventesimo giorno. I dati ottenuti suggeriscono che al fine della prevenzione degli incendi boschivi gli ovini dovrebbero essere utilizzati a turno con periodi di permanenza nei pascoli ad alta copertura di Brachypodium rupestre non superiori ai 10-12 giorni.

Incidenza di meningiti nell'ASL di Brescia nei primi mesi del 2003

Full Text Available

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�

Review on the NEI Methodology of Debris Transport Analysis in Sump Blockage Issue for APR1400

International Nuclear Information System (INIS)

Kim, Jong Uk; Lee, Jeong Ik; Hong, Soon Joon; Lee, Byung Chul; Bang, Young Seok

2007-01-01

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

Is the NEI-VFQ-25 a useful tool in identifying visual impairment in an elderly population?

Directory of Open Access Journals (Sweden)

Wormald Richard PL

2006-06-01

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

Effects of thyroid status on NEI concentration in specific brain areas related to reproduction during the estrous cycle.

2013-11-01

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

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.

Principles of diet therapy in ancient Chinese medicine: 'Huang Di Nei Jing'.

Science.gov (United States)

Ho, Z C

1993-06-01

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

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

In the Wu xing da yi (The Gist of Five Phases), written by Xiao Ji of the Sui Dynasty, there were 9 quotations cited from Huang di nei jing (Inner Canon of Huangdi). By comparison with current version of Huang di nei jing, most of the descriptions are similar, yet still with some differences, such as yin-yang nature of the five zang visceras, the liver being the root of "pi ji", the spleen being the root of "cang lin" etc. Wu xing da yi epitomizes the books about yin-yang and five phases before the Sui Dynasty, while Xiao Ji's quotations from Huang di nei jing interpreted from the views of yin-yang and five phases, are different from the annotations of later ages.

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

Comparison of scoring approaches for the NEI VFQ-25 in low vision.

Science.gov (United States)

Dougherty, Bradley E; Bullimore, Mark A

2010-08-01

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

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

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

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

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

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

Full Text Available Nel secolo scorso, e in special modo negli ultimi dieci anni, la questione dei media e, in particolare, il tema della media literacy ha attratto l’interesse delle autorità, degli studiosi e di altri responsabili nel settore educativo. Nel tempo sono entrati in uso molti concetti, ma sfortunatamente senza che ne venisse fornita una definizione, nella maggior parte dei casi. Questo articolo si focalizza sulla media literacy, su come può essere definita e sul significato di concetti affini utilizzati nel contesto finlandese. Inoltre viene discussa la relazione tra i concetti di media literacy e digital literacy e la collocazione della media literacy nei curricula scolastici in Finlandia. Il contributo affronta anche il problema della valutazione della media literacy nelle politiche istituzionali e chiude con un accenno alle prospettive future di ricerca nel campo dell’educazione ai media. Trattandosi di un lavoro di ampio respiro sulla media literacy, si riferisce sia a iniziative politiche che ai risultati della ricerca e alle pratiche educative.

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.

Full Text Available I due Neomys italiani sono ancora da chiarire dal punto di vista della loro caratterizzazione morfologica e ecologica. Il lavoro prende in considerazione un campione di entrambe le specie proveniente da habitat forestali dell?Appennino settentrionale per i quali sono stati identificati i principali parametri ambientali. Vengono quindi descritte la variabilità dei tratti morfologici delle due specie in aree localizzate nel Parco Nazionale Foreste Casentinesi, Monte Falterona e Campigna nell?Appennino tosco-romagnolo. Risultano di sicuro effetto discriminatorio la maschera facciale, il rapporto piede posteriore/coda e i caratteri cranici. Sulla base dei criteri identificativi si sono realizzate rilevazioni di misure corporee per le due specie e una comparazione degli habitat utilizzati. N. fodiens appare unica specie nelle faggete-abetine e dominante nei castagneti, mentre nell?Ontaneta e nelle zone aperte e termofile si registra la sola presenza di N. anomalus. Mancano entrambi nei prati cespugliati, nella pecceta e nella cerreta. I gradienti presenti sono quindi illustrati. Non appare una differenza altitudinale nel campione esaminato, posto in stazioni tra i 400 e i 1300 m, ma per entrambe vi sono maggiori riscontri nella fascia tra 700 e 850 m. Nell?analisi multivariata rispetto alle altre specie e alle variabili ambientali si riscontra sempre una discreta correlazione con la presenza di acqua di una certa ampiezza, che comunque è significativa solo per N. fodiens, mentre risulta di interesse la positiva correlazione di N. anomalus con Apodemus sylvaticus.

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

An experimental campaign on plate heat exchangers, used as evaporators and condenser in domestic refrigeration loops is presented in this paper. The research's purpose is to test the influence of some thermal-hydraulic parameters on the global overall heat transfer coefficient. R134a, R407C, R410A, and R22 are the fluids tested under reference thermal conditions. The experimental tests allows one to withdraw conclusions on the substitution effect on the thermal and global efficiency of the plant. Also, a new method for calculating the thermodynamical mixture parameters is applied to the condensation of mixtures R407C and R410A and its benefit evaluated. The refrigerant loop overall performance and the condenser global heat transfer coefficient are the parameters chosen to enlighten the characteristics of the alternative refrigerants (R134a, R407C, and R410A) with respect to the fluid that they are supposed to substitute (R22). [Italian] Scambiatori a piastre compatti impiegati come evaporatori e condensatori nei circuiti frigoriferi, sono l'oggetto della ricerca presentata in questo articolo. L'efficienza termica di tali componenti e' valutata in condizioni di riferimento commerciali. I refrigeranti utilizzati sono tre fluidi proposti per sostituire l'R22, un Hcfc, attualmente il refrigerante piu' utilizzato nel condizionamento ambientale. Una serie di prove condotte con quest'ultimo fluido consente di studiare gli effetti della sostituzione del fluido di progetto sulle prestazioni sia degli scambiatori, sia piu' in generale, dell'intero circuito frigorifero. In particolare sono state studiate le prestazioni di due coppie di evaporatori e condensatori in termini di coefficiente globale di scambio termico e di Cop dell'impianto. Nel presente lavoro e' inoltre presentato e utilizzato un metodo termodinamico per il calcolo della temperatura di saturazione per le miscele zeotropiche in bifase; uno dei refrigeranti

«Peripezia» ed «estasi della catastrofe»: figure della tragedia nei romanzi di Proust e Joyce

Directory of Open Access Journals (Sweden)

Raffaello Rossi

2017-12-01

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.

I sistemi biometrici lo sviluppo dei mercati negli Usa, UE e nel mondo. La normativa frena quello italiano

Directory of Open Access Journals (Sweden)

Franco Zucchetti

2007-04-01

Full Text Available Negli ultimi anni il settore biometrico sta compiendo, a livello mondiale, importanti passi in avanti soprattutto in termini di sviluppo e di diffusione. Questo trend positivo riguarda il mondo anglosassone e, in particolare, la realtà statunitense dove i sistemi biometrici vengono utilizzati, nelle più svariate situazioni, sia come controllo della sicurezza fisica delle persone, sia come terminali per l’autorizzazione all’accesso. La stessa diffusione non è riscontrabile nella maggior parte dei Paesi europei e in Italia dove raffrontiamo una realtà assai atipica nella quale la biometria fa un gran parlare di sé ma, in concreto, viene utilizzata con molta difficoltà. Tuttavia, un punto di contatto tra tutti gli attori europei ed extraeuropei può essere individuato nello sviluppo del settore relativo al riconoscimento biometrico applicato ai passaporti ed alle carte di identità. Il processo di globalizzazione ha generato, infatti, grandi masse di individui in continuo e costante movimento da un Paese all’altro e, contestualmente, ha prodotto una crescente domanda di sicurezza soprattutto nei confronti della minaccia terroristica. Appare chiaro, quindi, come l’identificazione certa delle persone diventi una necessità e debba presentare tecnologie simili per essere utilizzate ovunque.

EU proposal for a directive on incineration; Sull'incenerimento la proposta di direttiva del Consiglio UE

Energy Technology Data Exchange (ETDEWEB)

Salvia, L.

1999-04-01

New regulations on emission from waste incineration are under consideration of European Union. Besides hazardous waste - which is already the object of a 1994 directive - the new regulations will apply to all kinds of incinerated waste, with a net advantage of about 5000 milliard liras. As far as Italy is concerned, there shouldn't be a great change as regulations on the matter are, for many aspects, more advanced that those of other European countries. A specific regulation will deal with co-incineration, that is with waste used as fuel in plants producing electric energy. [Italian] L'Unione Europea ha allo studio una nuova normativa per disciplinare le emissioni legate all'incineramento dei rifiuti. Ad essere regolati saranno non solo quelli pericolosi, gia' oggetto di una direttiva del 1994, ma tutti i rifiuti smaltiti attraverso l'incenerimento. Le nuove regole dovrebbero portare un vantaggio netto di circa 5000 miliardi di lire. Per l'Italia non dovrebbe cambiare molto visto che la normativa in materia e' per molti aspetti piu' avanzata di quella di altri stati europei. Una disciplina a parte viene prevista per il coincenerimento, vale a dire per i rifiuti utilizzati come combustibile, sia nei cementifici che negli impianti per la produzione di energia elettrica.

Full Text Available

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

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

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

New Cricetid Rodents from Strata near the Eocene-Oligocene Boundary in Erden Obo Section (Nei Mongol, China).

Science.gov (United States)

Li, Qian; Meng, Jin; Wang, Yuanqing

2016-01-01

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.

Tempi che cambiano, luoghi che si trasformano: i mutamenti nei nuraghi fra l’età del Bronzo ed il Primo Ferro

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

Sono indagate le entità individuali: il loro isolamento all’interno della rete di soggetti e la relazione esemplificativa, il trattamento nelle classificazioni. Le profonde diversità rilevate fra concetti e entità denominate suggeriscono di dichiararle esplicitamente da un punto di vista teorico e di adottare dispositivi che diano risultati unitari ma chiaramente distinguibili nei sistemi di recupero dell’informazione.

Tuttavia , le loro conclusioni essenziali sono state già contenute nei primi articoli classici . L'autore si concentra su tre di essi ( Prebisch , Veggenti , Kaldor per sostenere che di un paese a tasso di crescita relativo  quella di un altro può essere approssimata dal rapporto tra la sua elasticità al reddito della domanda per le esportazioni verso la sua elasticità al reddito della domanda di importazioni.The Author looks at the difference in growth rates among countries and argues that they can be traced to the strength of the balance of payments position, determined largely by the propensity to export relative to the propensity to import. 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.

Donne attive in quanto militanti cattoliche. Tale scelta permette di considerare il modificarsi degli spazi d’azione femminile secondo il variare delle fasi storiche: dallo shock di fronte all’urto protestante alla rioganizzazione post-tridentina. L’analisi é condotta a partire da testi femminili (editi e inediti e dai loro contesti di produzione (dall’umanesimo erasmiano alla riconquista cattolica e iberica.

The article is devoted to secular and religious women’s agency in the framework of two different seasons of the confessional clash between Catholics and Protestants in the Early Modern Spanish Low-Countries. These women were catholic militants. The topic allow to follow changes in relation with female agency’s boundaries according to different periods: from the shocking time of Protestant first impact to the Catholic reset after the council of Trent. The analysis is based on printed and unprinted female texts, according to their context of production (the Erasmian humanism and the catholic and Spanish reconquest.The poetess and school teacher Anna Bijns as well as discalced Spanish Carmelites Ana de Jesús and Ana de San Bartolomé lived in Brussels and Antwerp.

2013-06-01

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

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

Comparative Study of Nei�s D with other Genetic Distance Measures between Barak Valley Muslims and other Nations for ABO Locus

Directory of Open Access Journals (Sweden)

Supriyo CHAKRABORTY

2012-02-01

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

In this work the stabilization of hazardous solid wastes containing heavy metals has been studied by means of novel matrices able to generate calcium trisulphoaluminate and silicate hydrates. The process is based on the hydration of two different mixtures containing blast furnace slag, coal ashes, chemical gypsum and Portland cement. The stabilization capacity of the two mixtures has been checked with regard to both a residue from an incinerator of municipal solid wastes and model systems obtained by adding 5 and 10% of soluble nitrates of Cd, Cr, Cu, Ni, Pb and Zn. The stabilized products have been validated from the point of view of mechanical properties by determining the unconfined compressive strength, and from the environmental point of view by means of static and dynamic leaching tests. Both matrices have proved to have great potentiality for the stabilization of hazardous solid wastes, the one based on blast furnace slag being better. Finally, evidence is given that different leaching tests are necessary to fully understand the immobilization mechanism responsible for stabilization. [Italiano] In questo lavoro e` stata studiata la atbilizzazione di residui tossici e nocivi contenenti metalli pesanti per mezzo di matrici leganti innovative capaci di generare trisolfoalluminato e silicato di calcio idrati. Il processo e` basato sull`idratazione di due diverse miscele contenenti scoria d`alto forno, ceneri di carbone, gessi chimici e cemento Portland. Le capacita` stabilizzanti delle due miscele sono state verificate sia nei confronti di un residuo solido generato a seguito dell`incenerimento di RSU, che nei confronti di sistemi modello ottenuti aggiungendo singolarmente il 5 e 10% dei nitrati solubili di Cd, Cr, Cu, Ni, Pb e Zn. I prodotti solidi stabilizzati sono stati validati dal punto di vista delle prestazioni meccaniche mediante prove di resistenza a compressione, e dal punto di vista ambientale mediante test di rilascio sia statici che dinamici

Full Text Available ItLa possibilità di accedere al Web mediante dispositivi mobili, ad esempio tablet o smartphone, ha comportato la creazione di ulteriori portali, semplificati, che consentono di diffondere contenuti ed informazione in maniera rapida ai propri utenti. Nel caso del servizio di Emeroteca Virtuale Mobile si è voluto ampliare la gamma dei servizi offerti all’utenza, includendo una piattaforma che fosse navigabile attraverso i browser disponibili nei moderni smart phone. L’analisi dei loro comportamenti ci ha permesso di verificare quanto gli utenti preferiscano i contesti mobili come ambienti di rapida verifica delle novità disponibili in Emeroteca, relativamente ai periodici di loro interesse (4 a 1 è infatti il rapporto tra la navigazione e la ricerca dei contenuti. Ciò chiarisce il ruolo che tale servizio sta assumendo nel contesto dell’Emeroteca, non alternativo a quello classico, ma, pur se ancora non privo di una sua connotazione sperimentale, certamente complementare a quest’ultimo.EnThe diffusion of the so called smart-phone and tablet among WEB users community caused a growth in the offering of specific portals, simplified comparing to the classic ones, but capable of a more direct and fast information flow towards their own users. Emeroteca Virtuale service too has been provided of a specific “mobile” portal dedicated to people having a smart-phone as a web access tool. Last two years usage data analysis on this service has revealed a peculiar behavior of Emeroteca Virtuale Mobile users: they tend to use the service as a rapid check of new entries in Emeroteca (issues or articles, specifically for those e-journals they are interested in (the ratio between browsing and search actions is 4 to 1. This clarifies better the role this “mobile” service is having versus the classical one: it is not an alternative to it, but a complementary way to get information from Emeroteca.

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/.

In the last 10 years several organic compounds have been used to realize efficient electro luminescent devices, which are being competitive with the well known and older semiconductor diodes LED. Among these new luminescent compounds, a special place is occupied by the metal-organic molecule Alq{sub 3}, which possesses an efficient band in the green region of the electromagnetic spectrum and is easily handled. However, the devices realised with Alq{sub 3} and other organic compounds, although several precautions have been implemented since the beginning, display a lifetime (defined as the time elapsed to get half emission intensity) of about 5000 h, which is considered a too short time for practical applications. The study of the chemical degradation of the molecule Alq{sub 3} and of the decrease of its photoluminescence has been the main concern of this work. The degradation has been attributed to the phenomenon of auto-oxidation, where the atmospheric oxygen plays a central role. Direct and simple experiments to verify whether the processes of auto-oxidation could be halted or retarded have been performed and, in the process, the organic compound BHT proved to be effective in attaining the desired effect. Indeed, this molecule belongs to the big family of Phenols which are well known in chemistry to be very strong antioxidant agents. In conclusion, the BHT compound and, by logical extension, other types of phenols and also appropriate organic compounds, are effective in increasing the lifetime of the photoluminescence of thin layers of Alq{sub 3} and, as a consequence, of OLED devices realized with molecules or polymers. This result is of great importance in the field of organic photo- and electro-luminescence both for practical and basic aspects.

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.

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

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

Obiettivi: misurare la direzione e l’entità delle disuguaglianze socio-economiche nell’abitudine al fumo in Italia durante gli ultimi due decenni, con attenzione sia al livello nazionale che macro-regionale.

Metodi: sono stati utilizzati dati provenienti da sei indagini ISTAT sullo stato di salute dal 1980 al 2000. Abbiamo usato il livello di istruzione come indicatore dello stato socio-economico. Per ogni indagine e livello di analisi (nazionale e macroregionale, è stata calcolata la prevalenza, standardizzata per età, del consumo di tabacco in diversi gruppi sociali.

Per ottenere una misura di sintesi delle disuguaglianze, abbiamo stimato l’Odds Ratio (OR ed il Relative Index of Inequality (con intervallo di confidenza al 95% attraverso un’analisi di regressione logistica.

Risultati: negli uomini di età compresa tra 25 e 49 anni, l’Odds Ratio del consumo di tabacco di una persona con un basso livello di istruzione confrontata con una di un alto livello è risultato pari a 1,26 (IC 95%: 1,16 - 1,37 nel 1980 ed a 1,71 (IC 95%: 1,62 - 1,80 nel 2000. Nelle donne della stessa fascia di età, l’associazione tra stato sociale ed abitudine al fumo si è trasformata da positiva (OR=0,43 in negativa (OR=1,12. Nelle donne più anziane, la prevalenza di fumatrici è risultata maggiore tra quelle più istruite, con un gap tra classi sociali che si restringe nel tempo. Nel periodo considerato le stime degli OR sono risultate costantemente inferiori nel Sud rispetto al Centro ed al Nord Italia, nonostante la somiglianza nei trend temporali nelle differenti macro-regioni.

Conclusioni: le disuguaglianze tra gruppi sociali sono aumentate, specialmente nelle giovani generazioni. Le regioni meridionali seguono quelle del centro e nord Italia nel diffondersi dell’epidemia dell’abitudine al fumo.

Introduction of developing a list of MSO generic scenarios for PHWR

Energy Technology Data Exchange (ETDEWEB)

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

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

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...

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...... (CINE; min/MJ of NE). Furthermore, we studied the forage-to-concentrate substitution rate in this new NEI model. To calibrate the model on a diverse set of situations, we built a database of mean intake from 14 production experiments with a total of 986 primi- and multiparous lactating dairy cows......, and disturbance, across and within experiments on independent data from 19 experiments including 812 primi- and multiparous lactating dairy cows of different breeds fed 80 different diets ad libitum. The NEI model predicted NEI with an MSPE of 8% of observed, and across the 19 experiments the error central...

Il particolare italiano da Guicciardini a Banfield. Tra l’autoriconoscimento e l’etero-riconoscimento

Directory of Open Access Journals (Sweden)

Pierluca Birindelli

2011-11-01

Full Text Available Nel 1958 la pubblicazione dell’indagine di Edward Banfield The Moral Basis of a Backward Society, suscitò un fervente dibattito nella comunità dei sociologi italiani e stranieri — la disputa sull’amoral familism, il concetto esplicativo centrale, è ancora aperta. Considerare primigenia l’interpretazione dello studioso statunitense è tuttavia un errore. Ampliando lo sguardo analitico si rintracciano spiegazioni analoghe e di gran lunga antecedenti dell’arretratezza sociale, economica e politica italiana: il “paese del tornaconto personale” di Leon Battista Alberti; il particulare di Guicciardini. L’idea di una mancanza strutturale (culturale? di senso civico da parte degli italiani affonda nei secoli e appartiene innanzitutto al momento dell’auto-riconoscimento identitario. Solo in un secondo tempo, con le note di viaggio del Grand Tour, questa rappresentazione entra a far parte dell’etero-riconoscimento nordeuropeo e molti anni dopo nordamericano. Quando un tratto identitario ottiene un “doppio riconoscimento” di così lunga durata, diviene un tòpos, un punto cardinale delle rappresentazioni individuali e collettive di un popolo. Chi sostiene tesi contrarie a Banfield si deve misurare con un altro ostacolo: la forza retorica dell’espressione “familismo amorale”. Tentare di costruire nuove e altrettanto efficaci locuzioni sintetiche, ovviamente frutto di buone interpretazioni teoriche, pare l’imprescindibile via ermeneutica da imboccare. A tal fine è necessario “dar battaglia” sullo stesso campo di indagine: un questionario difficilmente scalzerà i dispositivi narrativi costruiti attraverso le osservazioni etnografiche di un ricercatore che va sul campo — e che ci rimane per un anno. Se è chiaro che si può far meglio di Banfield, è pure chiaro che bisogna provarci. Esiste un’ulteriore barriera per chi intenda proporre diverse letture del processo di modernizzazione italiana: il peso della realt

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

Approcci innovativi alla mobilità urbana: il caso di Istanbul

Directory of Open Access Journals (Sweden)

Cecilia Scoppetta

2010-02-01

Full Text Available  L'attuale assetto dell'area metropolitana di Istanbul evidenzia con chiarezza il rapporto tra sistema della mobilità urbana ed espansione incontrollata del costruito. Gli strumenti di pianificazione utilizzati nel passato si sono rivelati inefficaci ed hanno prodotto una città in larga parte illegale che oggi appare ingovernabile. Tuttavia anche i nuovi strumenti del piano strategico e del progetto urbano sembrano mostrare i propri limiti. Una maggiore integrazione tra politiche urbane ancora troppo settoriali può contribuire alla definizione di approcci realmente innovativi.

Full Text Available The mechanisms of acupuncture are still unclear. In order to reveal the regulatory effect of manual acupuncture (MA on the neuroendocrine-immune (NEI network and identify the key signaling molecules during MA modulating NEI network, we used a rat complete Freund’s adjuvant (CFA model to observe the analgesic and anti-inflammatory effect of MA, and, what is more, we used statistical and complex network methods to analyze the data about the expression of 55 common signaling molecules of NEI network in ST36 (Zusanli acupoint, and serum and hind foot pad tissue. The results indicate that MA had significant analgesic, anti-inflammatory effects on CFA rats; the key signaling molecules may play a key role during MA regulating NEI network, but further research is needed.

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

Science.gov (United States)

Booth, Mary S.

2018-03-01

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

2015-08-01

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

Relationship between exercise capacity and left ventricular function at rest in patients with heart failure.

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. [Italian] Scopo di questo studio e' valutare se la capacita' di esercizio, determinata mediante il consumo di ossigeno e la funzione ventricolare sinistra, sia correlata alla funzione ventricolare sinistra a riposo nei pazienti con insufficienza cardiaca. Sono stati studiati 17 pazienti con insufficienza cardiaca di origine ischemica.

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

Directory of Open Access Journals (Sweden)

2014-07-01

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

Che relazione instaurare tra la didattica tradizionale e le novità telematiche? Come trasmettere agli alunni la continuità tra gli argomenti trattati a lezione e le chat “improvvisate” in laboratorio?

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

Full Text Available I bambini sono affascinati dai tablet e dai dispositivi mobili di ultima generazione. Allo stesso modo si trovano in una fase della vita in cui iniziano a formare preferenze e competenze così come ad esprimere le proprie emozioni e sensazioni attraverso la parola. Questo articolo descrive le strategie per la creazione di applicazioni (app per bambini che siano non solo divertenti ma anche efficaci per esperienze significative che li coinvolgano a livello cognitivo ed emotivo. Quando si disegnano app rivolte ai bambini occorre ricordare che i più piccoli non hanno ancora chiaro come dovrebbe funzionare una specifica tecnologia ma si stanno formando un’opinione a riguardo. Diventa dunque necessario considerare alcuni principi di interaction e visual design affinché l’esperienza vissuta con il tablet incontri bisogni e competenze.

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

Full Text Available La costruzione di schemi di classificazione dei record è un tema poco sviluppato a cui la disciplina archivistica ha finora dedicato poca attenzione. Non si tratta di un argomento di facile comprensione, dal momento che gli schemi di classificazione dei record sono gli strumenti principali utilizzati tradizionalmente per l'organizzazione e la gestione dei record. Questo articolo esamina gli elementi presi in considerazione nella costruzione di uno schema di classificazione, così come le modalità attraverso le quali questi elementi sono correlati. Vengono inoltre esaminate le relazioni gerarchiche e non gerearchiche, ed identificate le possibili future direzioni della ricerca su questi temi.

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

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

Of the possible routes to connect Caucasian and Central Asian oil to market, the `Iranian connection` is the most interesting. The economic attraction of the Iranian route is clear: large transport capacities exist in the various pieces of Iran`s existing network, large refining centers are located near the Caspian and there ate unutilized export terminals. [Italiano] Tra le vie possibili per assicurare uno sbocco ai mercati al petrolio caucasico e dell`Asia centrale, la `via iraniana` e` la piu` interessante. L`attrazione economica di questa via e` chiara: nel sistema di oleodotti dell`Iran sussistono ampie capacita` di trasporto, grandi centri de raffinazione sono localizzati vicino al Caspio e ci sono terminali di esportazione non utilizzati.

Meningococco B: controllo di due focolai epidemici mediante vaccinazione

Science.gov (United States)

2014-01-01

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

Use by small mammals of short-rotation plantations in relation to their structure and isolation

Directory of Open Access Journals (Sweden)

Marta Giordano

2010-06-01

Full Text Available Abstract Over the last decades, dramatic changes in agricultural practices have led to important modifications of land-use, as well as landscape structure, and to a general biodiversity loss in agro-ecosystems. During 2008 we investigated the small mammal communities of Short Rotation Forestry (SRF stands in Northern Italy. We live-trapped small mammals, during summer and autumn, in different types of SRF stands and surrounding habitats and compared capture rates. We evaluated the influence on small mammals abundance of the distance between the stands and other habitats offering woody or bushy cover. Our results showed that SRF plantations are widely exploited by small mammals, especially in autumn and that capture rate is the highest in “double-row” stands. The distance from woods or other arboriculture stands was negatively correlated to small mammals abundance. We conclude that SRF plantations can be considered a suitable habitat for small mammals and may work as a “corridor habitat” between fragmented patches of suitable habitats.
Riassunto Uso degli impianti a turno breve da parte dei micrommamiferi, in relazione alla loro struttura e isolamento Negli ultimi decenni profondi cambiamenti nelle pratiche agricole hanno causato modifiche nella tipologia di uso dei terreni, così come nella struttura del paesaggio, che hanno portato a una generale perdita di biodiversità negli agroecosistemi. Nel corso del 2008 abbiamo studiato le comunità di micromammiferi nelle piantagioni di pioppo per la produzione di biomassa (SRF nel Nord Italia. Con l’uso di live-traps abbiamo effettuato due sessioni di cattura, una estiva e una autunnale, nei diversi tipi di impianto delle SRF e negli ambienti circostanti, per comparare le frequenze di cattura. Abbiamo quindi analizzato l’influenza che la distanza tra i diversi ambienti con copertura arborea ha sull’abbondanza dei micromammiferi

Full Text Available Normal 0 14 false false false IT X-NONE X-NONE MicrosoftInternetExplorer4 Abstract English language teaching materials usually reflect both the explicit and the implicit attitudes and beliefs of their authors, of the society and the culture of the times they live in. Attitudes and beliefs are bound to change over time and are affected by socio-cultural changes, particularly in areas such as power relationships, the image of women and that of identity construction. The first coursebook analyses in terms of women’s representations and sexist attitudes date back to the 70s and the 80s (e.g. Hartman, Judd 1978; Stern 1976; Porreca 1984; Schmitz 1975, 1984 and have been greatly influenced by language and gender studies (e.g. Sunderland 1992, 1994, 2000; Sunderland, Litosseliti 2002; Cameron 2005. This paper is aimed at presenting the results of a study on how women and their voices have been portrayed in ELT coursebooks addressed to Italian students over time. The analysis carried out in a diachronic perspective, have specifically focussed upon textbooks published between the 1950s and the beginning of the 80s in order to represent different historical perspectives. The proposed stretch in time to the 80s is aimed at investigating the most relevant shifts occurring in ELT coursebooks in the 70s as a consequence of changes in society and the influence of gender studies. The categories used to analyse the ELT materials have been: the representation (as well as the omission of women and their roles in texts and illustrations; the language used to refer to women and its role in maintaining, diminishing or reinforcing sexist values. Despite a correspondence between gender representations and ongoing changes in society, the textbooks examined appear to represent more traditional than innovative views on women.

Full Text Available Aim of the present study is to analyze the international market of the ostomy devices in Italy, France, Germany, U.K. and Denmark. The ostomy systems are technologically mature devices, and the more interesting market developments are about innovative modality of distribution and patients technical support, like home distribution. For every country it has been applied a common pattern, based on four aspect of the ostomy devices market: 1. the legislative aspect; 2. the prescription procedure; 3. the different models of distribution; 4. the competitive systems of pharmaceutical industry. All the data in this study has been galthered through relevant literature and interviews with the area operators. The ostomy devices are repayable against medical prescription in all the studied countries; significant legislative differences are registered in the repayment prices determination. For all the studied countries, in the decisional process related to the choice of one or another device, the essential role is played by the ostomy hospital nurse, that advises the patient immediately after the surgery. Finally, the more significant examples to innovate purchase and distribution process of ostomy devices in Italy comes from Denmark and U.K., where the home distribution is already available and it is working.

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

Full Text Available Breaking Bad è una serie per molti aspetti indecidibile nel genere, che presenta un’intertestualità aperta e cangiante, tra serialità televisiva e cinema d’autore (ad esempio tra western e poliziesco, e si apre all’innovazione intermediale, data non solo dall’ibridazione dei generi e della fiction seriale con il cinema, ma dai modi metadiscorsivi (o 'metacinematografici' e da soluzioni che lavorano sui bordi dei media e sulla loro porosità grazie alle nuove tecnologie digitali. Passando attraverso esempi di modi traduttivi e reinterpretativi, intertestuali e intermediali, transmediali e crossmediali, cercherò di analizzare alcuni meccanismi di funzionamento degli attuali ecosistemi mediali seriali in Breaking Bad. Ad esempio nelle citazioni dirette e indirette, nelle aperture intertestuali e intermediali, ma anche nei teaser e nei recaps, nei webisode e nelle proliferazioni crossmediali delle pratiche dei remixer, distinguendo tra ripetizione e innovazione, tra modi centripeti e centrifughi dello storytelling e, per i remix, tra modi della selezione e modi della collezione.

It was preliminarily reviewed that 41 scenarios of 63 scenarios of NEI's generic list could be applicable to design of SKN3. And 22 scenario of NEI's generic list were evaluated not applicable to SKN3. During the review of the scenario contained in NEI 00-01, no additional MSO scenarios specific to SKN3 were identified. For the further study, the final review will be determined and then detailed circuit analysis will be performed by fire zone and area based on the exact location contained the cable and raceway. With the enhancement of fire safety regulation requirements in nuclear power industry, multiple spurious operation (MSO) identification and treatments should be included in post fire safe shutdown analysis (PFSSA). In this study, the MSO scenario reviews are performed for Shin Kori Unit 3(SKN3) which is the first nuclear power plant of the Advanced Power Reactor 1400 constructed in Korea.

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

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.

A combinatorial role for MutY and Fpg DNA glycosylases in mutation avoidance in Mycobacterium smegmatis.

Science.gov (United States)

Hassim, Farzanah; Papadopoulos, Andrea O; Kana, Bavesh D; Gordhan, Bhavna G

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

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

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

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

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

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

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

Questo libro, che nasce dall’esperienza didattica accumulata dall’autore nell’insegnamento dei metodi sperimentali, si propone di fornire un’introduzione al calcolo delle probabilità e alla teoria degli errori facendo uso di uno stile di presentazione volutamente informale e traendo spunto da concrete applicazioni sperimentali, spesso attraverso esempi di notevole importanza storica. Così, per esempio, argomenti quali il moto browniano, la diffusione di luce, il decadimento radioattivo, la fisiologia della visione, le statistiche quantistiche e di fotorivelazione, vengono utilizzati per delucidare concetti chiave dell’analisi statistica e probabilistica. Un'enfasi particolare è posta sull’origine e l...

Full Text Available A trial was conducted to: i evaluate the BW growth, energy intakes and energetic efficiency of pigs fed high and low density diets from 27 to 141 kg BW, ii evaluate sire line and sex differences when fed both diets, and iii to compare ME to NE as predictor of pig performance. The experiment had a replicated factorial arrangement of treatments including four sire lines, two sexes (2,192 barrows and 2,280 gilts, two dietary energy densities and a light or heavy target BW, 118 and 131.5 kg in replicates 1 to 6 and 127 and 140.6 kg in replicates 7 to 10. Pigs were allocated to a series of low energy (LE, 3.27 Mcal ME/kg corn-soybean meal based diets with 16% wheat midds or high energy diets (HE, 3.53 to 3.55 Mcal ME/kg with 4.5 to 4.95% choice white grease. All diets contained 6% DDGS. The HE and LE diets of each of the four phases were formulated to have equal lysine:Mcal ME ratios. Pigs were weighed and pen feed intake (11 or 12 pigs/pen recorded at 28-d intervals. The barrow and gilt daily feed (DFI, ME (MEI and NE (NEI intake data were fitted to a Bridges function of BW. The BW data of each sex were fitted to a generalized Michaelis-Menten function of days of age. ME and NE required for maintenance (Mcal/d were predicted using functions of BW (0.255 and 0.179 BW^0.60 respectively. Pigs fed LE diets had decreased ADG (915 vs. 945 g/d, p<0.001 than pigs fed HE diets. Overall, DFI was greater (p<0.001 for pigs fed the LE diets (2.62 vs. 2.45 kg/d. However, no diet differences were observed for MEI (8.76 vs. 8.78 Mcal/d, p = 0.49 or NEI (6.39 vs. 6.44 Mcal/d, p = 0.13, thereby indicating that the pigs compensated for the decreased energy content of the diet. Overall ADG:DFI (0.362 vs. 0.377 and ADG:Mcal MEI (0.109 vs. 0.113 was less (p<0.001 for pigs fed LE compared to HE diets. Pigs fed HE diets had 3.6% greater ADG:Mcal MEI above maintenance and only 1.3% greater ADG:Mcal NEI (0.152 versus 0.150, therefore NEI is a more accurate predictor of

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

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

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

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

Assessing the Impact of Oil and Natural Gas Activities on Regional Air Quality in the Colorado Northern Front Range using WRF-Chem

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

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

Enhancing the effectiveness of IST through risk-based techniques

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

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

Improving the security of a plant's Distributed Control System (DCS) is an important consideration for plant safety and profitability, as well as the necessity to comply with the regulation. The U.S. Nuclear Regulatory Commission has produced Regulatory Guide (RG) 5.71, and the Nuclear Energy Institute (NEI) has produced NEI 08-09 to assist plants in meeting 10 CFR 73.54, Protection of digital computer and communication systems and networks. These requirements, which address the establishment, implementation and maintenance of a cyber security program, present challenges to ensure that safety, security and emergency preparedness functions of nuclear facilities are not negatively impacted by the vulnerability scanning and testing process.

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

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

simpaticectomia lombare e un'opzione terapeutica complementare, destinata a quei pazienti con grave arteriopatia perierica degli srti inferiori, allo stadio terminale, che presentino dolore a riposo e gagrena e che non vengano riconosciuti idonei per un tentativo di rivascolarizzazione chirurgica. La simpatectomia lombare chirurgica, con tecnica tradizionale, e stata ampiamente utilizzata in passato, ma, in virtu dell'invasivita, e stata nel tempo accantonata a favore delle tecniche percutanee, anche se recentemente sono stati riportati casi di trattamento con tecnica laparoscopica. La simpaticectomia lombare percutanea e invece un'opzione terapeutica sicura, poco costosa e facilmente disponibile. Riportiamo la nostra esperienza su 19 casi, eseguiti sotto controllo TC. Materiale e metodi: Tra il 1998 e il 2002, la procedura di simpaticolisi percutanea sotto controllo TC e stata effettuata in 19 pazienti. Tutti i pazienti presentavano un'arteriopatia degli arti inferiori al IV stadio di Fontaine, con dolore a riposo e gangrena; non erano stati considerati idonei per un tentativo di rivascolarizzazione chirurgica. Due aghi da 22 G, lunghi 15 cm, sono stati utilizzati per iniettare fenolo a livello di L2 e L4. I segni dell'interruzione dell'attivita simpatica compaiono 2'-15' dopo la procedura e comprendono calore e arrossamento. Risultati: La procedura si e rivelata semplice, sicura, ben tollerata dai pazienti, con una bassa percentuale di complicanze. Dei 19 pazienti, 9 (47.3%) hanno mostrato un miglioramento del quadro clinico, mentre 5 hanno fatto registrare un peggioramento della loro condizione ischemica nei mesi successivi. Discussione: I risultati suggeriscono che la procedura di simpaticectomia lombare percutanea e in grado di causare un blocco del plesso simpatico nei pazienti con un'arteriopatia degli arti inferiori in fase avanzata. L'assistenza fornita dalla TC consente un'elevata precisione nella somministrazione

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

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

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

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

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

Improving the security of a plant's Distributed Control System (DCS) is an important consideration for plant safety and profitability, as well as the necessity to comply with the regulation. The U.S. Nuclear Regulatory Commission has produced Regulatory Guide (RG) 5.71, and the Nuclear Energy Institute (NEI) has produced NEI 08-09 to assist plants in meeting 10 CFR 73.54, Protection of digital computer and communication systems and networks. These requirements, which address the establishment, implementation and maintenance of a cyber security program, present challenges to ensure that safety, security and emergency preparedness functions of nuclear facilities are not negatively impacted by the vulnerability scanning and testing process.

Per l'analisi dell'oralità nei cantari

Anna Spiazzi

2016-12-01

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.

Cibo e scrittura nei romanzi di Stefano Benni

Directory of Open Access Journals (Sweden)

Francesca Nava

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.

Integrazione trasporti territorio nei PUM: esperienze a confronto

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

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

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

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

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

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

Steam Generators (SGs) are a key component of PWR nuclear power plants, maintaining their structural integrity throughout their life time is necessary to allow for long term operation (LTD) of PWR plants. NEI 97-06 provides the fundamental elements to be included in a SG Program. In addiction it describes performance criteria that SG tubes have to meet in order to provide reasonable assurance that the tubes are still able to maintain specific safety function. Hence, it is mandatory for plants with SGs to have defined a SG program consistent with NEI 97-06 and contains the elements which are described by it. This Program must contain some elements such as, Degradation Assessment, inspection and Integrity Assessment, among other. (Author)

The RiGOR study evaluated the association of treatment and patient-reported outcomes for open-angle glaucoma patients. The Glaucoma Symptom Scale (National Eye Institute-Visual Function Questionnaire (NEI-VFQ) and visual acuity (VA) were collected as quality of life measures. The proportion of patients with improvement of at least two lines of vision was highest in the incisional surgery group (14.2% compared with 9.9% for laser surgery and 10.9% for additional medication). No clinically relevant differences were seen in benefit for the laser surgery or incisional surgery groups compared with additional medications for the Glaucoma Symptom Scale or NEI-VFQ measures or subscales. Differences in quality of life by race need to be explored in further studies.

Observational evidence for the relationship between spring soil moisture and June rainfall over the Indian region

Science.gov (United States)

KanthaRao, B.; Rakesh, V.

2018-05-01

Understanding the relationship between gradually varying soil moisture (SM) conditions and monsoon rainfall anomalies is crucial for seasonal prediction. Though it is an important issue, very few studies in the past attempted to diagnose the linkages between the antecedent SM and Indian summer monsoon rainfall. This study examined the relationship between spring (April-May) SM and June rainfall using observed data during the period 1979-2010. The Empirical Orthogonal Function (EOF) analyses showed that the spring SM plays a significant role in June rainfall over the Central India (CI), South India (SI), and North East India (NEI) regions. The composite anomaly of the spring SM and June rainfall showed that excess (deficit) June rainfall over the CI was preceded by wet (dry) spring SM. The anomalies in surface-specific humidity, air temperature, and surface radiation fluxes also supported the existence of a positive SM-precipitation feedback over the CI. On the contrary, excess (deficit) June rainfall over the SI and NEI region were preceded by dry (wet) spring SM. The abnormal wet (dry) SM over the SI and NEI decreased (increased) the 2-m air temperature and increased (decreased) the surface pressure compared to the surrounding oceans which resulted in less (more) moisture transport from oceans to land (negative SM-precipitation feedback over the Indian monsoon region).

This study therefore aimed to assess the effect of strabismus on the vision-related QoL of Chinese teenagers.Methods: The Chinese version of the 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ-25 was self-administered by 1,040 teenagers with strabismus and 1,002 individuals with normal vision. All the participants were from the Chinese Han population. The independent samples t-test was used to compare QoL between teenagers with and without strabismus.Results: The majority of scores on the NEI-VFQ-25 domains were significantly different between the two groups. QoL was significantly lower in individuals with strabismus compared with teenagers with normal vision on all domains, with the exception of social functioning.Conclusion: Statistically significantly lower vision-related QoL scores were found in Chinese Han teenagers with strabismus compared with those without strabismus.

Full Text Available We conducted a questionnaire survey using a cross-sectional sample of early and middle adolescents aged 10–15 (n = 351 in order to investigate relationships between temperament, metacognition, and frames of reference in behaviors in public situations. The sample was divided into two groups by age (ear group: 10–12; middle-adolescence group: 13–15 and were analyzed by Multiple Group Structural Equation Modeling. Explanatory variables were four components of temperament [effortful control (EfC, affiliativeness (Afil, surgency (Sur, and negative affect (NgA] and metacognition. Objective variables were three components of frames of reference in behaviors in public situations [egocentrism (Ego, neighborhood evaluation (Nei, and public values (Pub]. In both age groups, EfC had a negative effect on Ego, and Sur had a negative effect on Nei. However, only in the middle-adolescence group did Afil and NgA have significant effects on Pub. Meanwhile, metacognition in the ear group had a positive effect on Ego and Nei, but these relations disappeared in the middle-adolescence group, and only in the middle-adolescence group did metacognition have a positive effect on Pub. We discuss frames of reference in behaviors in public situations from the viewpoint of the development of social cognition in early and middle adolescence in relation to temperament and metacognition.

Heat recovery with heat pumps in non-energy intensive industry: A detailed bottom-up model analysis in the French food and drink industry

International Nuclear Information System (INIS)

Seck, Gondia Sokhna; Guerassimoff, Gilles; Maïzi, Nadia

2013-01-01

Highlights: • First bottom-up energy model for NEI at 4-digit level of NACE for energy analysis. • Energy end-use modelling due to the unsuitability of end-product/process approach. • Analysis of heat recovery with HP on industrial processes up to 2020 in French F and D. • Energy consumption and emissions drop respectively by 10% compared to 2001 and 9% to 1990. • Results only achieved at heat temperature below 100 °C, concentrated in 1/3 of F and D sectors. - Abstract: Rising energy prices and environmental impacts inevitably encourage industrials to get involved in promoting energy efficiency and emissions reductions. To achieve this goal, we have developed the first detailed bottom-up energy model for Non-Energy Intensive industry (NEI) to study its global energy efficiency and the potential for CO 2 emissions reduction at a 4-digit level of NACE classification. The latter, which is generally neglected in energy analyses, is expected to play an important role in reducing industry energy intensity in the long term due to its economic and energy significance and relatively high growth rate. In this paper, the modelling of NEI is done by energy end-use owing to the unsuitability of the end-product/process approach used in the Energy Intensive industry modelling. As an example, we analysed the impact of heat recovery with heat pumps (HP) on industrial processes up to 2020 on energy savings and CO 2 emissions reductions in the French food and drink industry (F and D), the biggest NEI sector. The results showed HP could be an excellent and very promising energy recovery technology. For further detailed analysis, the depiction of HP investment cost payments is given per temperature range for each F and D subsector. This model constitutes a useful decision-making tool for assessing potential energy savings from investing in efficient technologies at the highest level of disaggregation, as well as a better subsectoral screening

2012-12-01

Full Text Available Obiettivo del presente contributo è analizzare la struttura di due noti romanzi sardi, Il figlio di Bakunìn di Sergio Atzeni e Gli arcipelaghi di Maria Giacobbe, caratterizzati da una narrazione in prima persona, e dimostrare come il materiale narrativo è riorganizzato e riplasmato nelle trasposizioni cinematografiche, dirette rispettivamente da Gianfranco Cabiddu (1997 e da Giovanni Columbu (2001. La locuzione impiegata per riferirsi ai film è quella di traduzione intersemiotica, che riprende la terminologia del linguista Roman Jakobson. In questo modo, si vogliono mettere in evidenza l’intento dei registi di ricreare i fili narrativi dei romanzi e la volontà di riproporre, reintepretandoli, i punti di vista di ciascun personaggio. In un secondo momento, l’attenzione sarà rivolta alle scelte linguistiche adottate nei romanzi e nei film.

Il «pulvis et umbra» oraziano in alcuni poeti latini tardoantichi

Directory of Open Access Journals (Sweden)

Elena Castelnuovo

2015-08-01

Full Text Available L’affermazione di Orazio pulvis et umbra sumus (Carm. 4.7.16 ha lasciato un’impronta nei poeti successivi? Scopo dell’articolo è analizzare l’influenza di un tale verso su tre autori tardoantichi: Ausonio, Paolino di Nola e Venanzio Fortunato. Essi si rifanno al modello in modi differenti: se Ausonio si limita a riprodurre il verso di Orazio, Paolino, invece, riprende i termini pulvis et umbra aggiungendovi sine Christo, per mettere in luce la diversità fra la visione pagana e la sua concezione di vita rinnovata dalla conversione. Inoltre, echi dalle Scritture nei due passi di Paolino e di Venanzio portano a una ricchezza di significato dovuta all’incontro fra la tradizione classica e quella biblica. Un’appendice tenta di rispondere alla domanda su quale testo del Salterio conoscesse Paolino.

,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.

The paper analyses some possible applications of Opf techniques to the new market scenario of electric systems. New control tools (the adoption of Facts devices, or the use of correct economical signals related to nodal prices) are introduced. As the technical and economic requirements of the market could give rise to mutual conflict, the use of Multi objective Optimisation (MO) is envisaged. MO allows the management of different objectives and makes it easier to take a decision, as it gives indications on the consequences of the choice with respect to all the objective functions considered. [Italian] A partire dai criteri di ottimizzazione applicati alla pianificazione e all'esercizio dei sistemi elettrici gestiti in maniera tradizionale, l'articolo illustra alcune proposte di Optimal Power Flow (Opf) per il nuovo regime di mercato. Sono presentate due possibili evoluzioni dei metodi tradizionali di Opf, che considerano la presenza di carichi elastici o di dispositivi per la gestione flessibile della rete di trasmissione (Facts). Si riportano anche alcuni risultati ottenuti applicando al problema di Opf metodi di multiobiettivo, utili per contemperare le necessita' dei diversi attori del mercato.

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.
