Positron production using a 9 MeV electron linac for the GBAR experiment
2020
For the GBAR (Gravitational Behaviour of Antihydrogen at Rest) experiment at CERN's Antiproton Decelerator (AD) facility we have constructed a source of slow positrons, which uses a low-energy electron linear accelerator (linac). The driver linac produces electrons of 9 MeV kinetic energy that create positrons from bremsstrahlung-induced pair production. Staying below 10 MeV ensures no persistent radioactive activation in the target zone and that the radiation level outside the biological shield is safe for public access. An annealed tungsten-mesh assembly placed directly behind the target acts as a positron moderator. The system produces $5\times10^7$ slow positrons per second, a performan…
A sustainable city environment through child safety and mobility:A challenge based on ITS?
2012
Our cities should be designed to accommodate everybody, including children. We will not move toward a more sustainable society unless we accept that children are people with transportation needs, and ‘bussing’ them around, or providing parental limousine services at all times, will not lead to sustainability. Rather, we will need to make our cities walkable for children, at least those above a certain age. Safety has two main aspects, traffic safety and personal safety (risk of assault). Besides being safe, children will also need an urban environment with reasonable mobility, where they themselves can reach destinations with reasonable effort; else they will still need to be driven. This p…
Safety and immunogenicity of the therapeutic vaccine TG1050 in chronic hepatitis B patients: a phase 1b placebo-controlled trial
2020
Funding: Transgène; International audience; Treatment of chronic hepatitis B (CHB) typically requires life-long administration of drugs. Cohort and pre-clinical studies have established the link between a functional T-cell-mounted immunity and resolution of infection. TG1050 is an adenovirus 5-based vaccine that expresses HBV polymerase and domains of core and surface antigen and has shown immunogenicity and antiviral effects in mice. We performed a phase 1 clinical trial to assess safety and explore immunogenicity and early efficacy of TG1050 in CHB patients. This randomized, double blind, placebo-controlled study included two sequential phases: one single dose cohort (SD, n = 12) and one …
Combined hexavalent diphtheria-tetanus-acellular pertussis-hepatitis B-inactivated poliovirus-Hemophilus influenzae type b vaccine; Infanrix™ hexa: T…
2014
Infant vaccination using 2-dose priming at 3 and 5 mo of age with a booster at 11–12 mo of age was pioneered in Italy. The 3-5-11 schedule is now used in a growing number of European countries. Infanrix™ hexa (DTPa-HBV-IPV/Hib, GlaxoSmithKline Vaccines) was first licensed for use in 2000 and has been the only pediatric hexavalent vaccine available since 2005. We reviewed available clinical trial data describing the immunogenicity of DTPa-HBV-IPV/Hib when administered at 3, 5, and 11 mo of age, and conducted an analysis of safety using global and Italian post-marketing surveillance data. In Italy, DTPa-HBV-IPV/Hib has a demonstrated safety record extending over a decade of use, it has been a…
Bezpieczeństwo komunikacyjne uczniów w drodze do/ze szkoły
2016
Bezpieczeństwo Komunikacyjne to zagadnienie, które dotyczy bezpośrednio wszystkich ludzi: kierowców, pieszych, rowerzystów, motocyklistów. Artykuł ma na celu przedstawienie podstawowych zagadnień dotyczących bezpieczeństwa komunikacyjnego oraz ukazanie poziomu bezpieczeństwa w drodze do szkoły uczniów w mieście Opole oraz poziomu wiedzy uczniów na temat bezpieczeństwa komunikacyjnego. Szczegółowo przeanalizowano i zwrócono uwagę na sposoby pokonywania przez uczniów drogi do/ze szkoły, poczucie bezpieczeństwa uczniów w ich opinii, oraz wiedzę uczniów na temat ruchu drogowego.
Environment and health in the Accra metropolitan area, Ghana
2004
Kwasi Boadi tutki väitöskirjassaan kotitalouksien ympäristöongelmia sekä niiden vaikutuksia eri sosiaaliluokkien terveyteen Accrassa, Ghanassa. Hän havaitsi, että köyhyys, puutteelliset tilat ja välineet, ympäristöterveystiedon puute sekä köyhien tarpeiden huomiotta jättäminen päätöksenteossa ovat suurimmat esteet hyvän ympäristöterveyden saavuttamiselle Accrassa. Ympäristöterveyden parantaminen vaatii vesihuollon parantamista, puhtaanapidon, jätteiden käsittelyn ja asuntojen ilmastoinnin kohentamista, huono-osaisten asuinalueiden terveyspalveluiden parantamista sekä ohjelmia, jotka lisäävät tietoisuutta ympäristöterveyteen liittyvissä asioissa. Inadequate provision of environmental health …
Homeostatic control of polyamine levels under long-term salt stress in Arabidopsis
2011
Salt stress has been frequently studied in its first osmotic phase. Very often, data regarding the second ionic phase is missing. It has also been suggested that Putrescine or/and Spermine could be responsible for salt resistance. In order to test this hypothesis under long-term salt stress, we obtained Arabidopsis thaliana transgenic plants harboring pRD29A::oatADC or pRD29A::GUS construction. Although Putrescine was the only polyamine significantly increased after salt acclimation in pRD29A::oatADC transgenic lines, this rendered in no advantage to this kind of stress. The higher Spermine levels found in WT and transgenic lines when compared to control conditions along with no increment o…
Assessing HYDRUS-2D model to simulate water content and salt accumulation in a soil irrigated with a subsurface drip system: Application in a semiari…
2015
In this paper, the suitability of HYDRUS-2D model to predict the average soil water content in the root zone of potato crop irrigated with subsurface drip irrigation plant, is initially assessed on the basis of a field study. Then, the model is tested to predict the salt distribution around a buried emitter, when two different water qualities (i.e. electrical conductivity of 1.0 dS m-1 and 4.0 dS m-1), are used during the growing season (treatments T1 and T2). Finally, the soil volume in which salts accumulates, as well as the effects on crop yield is recognized for both the considered treatments.The results evidenced that predicted values of average soil water content in the root zone were…
Il reliquiario a statua di San Nicasio
2016
Il saggio tratta del reliquiario argenteo di tipologia antropomorfa custodito nella chiesa della Santissima Annunziata di Caccamo, in provincia di Palermo. Lo studio è l'esito di una attenta analisi del manufatto realizzata in occasione dello smontaggio effettuato per procedere a specifici interventi di restauro. L'opera viene contestualizzata nell'ambito della attuazione in Sicilia delle istanze controriformate.
LA IMPORTANCIA DEL DINERO EN LA ELECCIÓN LABORAL
2014
Resumen: El objetivo fundamental del presente articulo es identificar los factores motivadores del trabajo entre los futuros directivos y trabajadores y reflexionar desde un punto de vista tanto academico como profesional sobre la importancia del dinero como factor motivador. Para ello, hemos tomado a estudiantes universitarios, en su faceta de futuros trabajadores; se concluye que el dinero por si solo no motiva y que es necesario encontrar aquel grupo de factores que motivan a los trabajadores con el objetivo de conseguir el maximo rendimiento. Los resultados nos permiten concluir que no debemos motivar tan solo con el dinero o admitiendolo como principal elemento motivacional. Palabras c…
