Eficacia de las marcas viales transversales tipo chevron en la reducción de velocidad de vehículos ligeros en intersección
2012
El objetivo de la tesis es comprobar la eficacia de las marcas viales transversales tipo chevron sobre la reducción de la velocidad de los vehículos ligeros en intersección de carretera convencional. Para alcanzar el objetivo se utilizó un diseño de tipo selectivo longitudinal de poblaciones con muestras independientes sucesivas. Se registró la velocidad de los vehículos en cuatro momentos temporales: i) antes de incluir los chevrons; ii) inmediatamente después de incorporar los chevrons; iii) a los tres meses y, iv) a los seis meses. La zona en la que se incluyeron los chevrons fue desde el pk 10+550 al pk 10+850 próxima a una intersección, en la CV-50 dirección Tavernes de la Valldigna-Al…
Marco Internacional de Acciones. VIH/SIDA, Tuberculosis, Malaria y Drogas
2002
El SIDA/VIH en el marco las enfermedades infecciosas, y en su relación con el consumo de drogas ha sido considerado por el Consejo Nacional de Seguridad de los EE.UU. como una cuestión de seguridad mundial y una amenaza para la democracia global. En este trabajo se expone de modo esquemático el estado actual a escala mundial de la investigación e intervención económica y social respecto a este problema fundamen¬talmente dentro del ámbito de proyección de la Unión Europea, Naciones Unidas y las respectivas Organizaciones Mundiales de la Salud, del Desarrollo Económico y del Comercio.

Dianthus superbus as a critically endangered species in Latvia: evaluation of its growth conditions and conservation possibilities
2021
Abstract Dianthus superbus is one of the most endangered species in Latvia and is on the verge of local extinction. Therefore, the aim of this study was to inventory previously identified populations of D. superbus in Latvia and to develop activities to conserve this species in accordance with the results obtained in situ. Expeditions on 18 previously documented locations, according to the data of Nature Conservation Agency, revealed only three existing D. superbus localities in Latvia with a significant number of specimens located in the Latgale region near Silenieki. In 2020, for the first time, two more new D. superbus localities were found in the vicinity of these three approved locatio…
Acute Promyelocytic Leukemia during Pregnancy: A Systematic Review of the Literature
2020
The management of pregnant women with acute promyelocytic leukemia (APL) is a challenging situation where limited evidence-based information is available. We performed a systematic literature review to analyze the outcomes reported for both mother and fetus when APL is diagnosed during pregnancy. PubMed, Scopus and Web of Science databases were systematically searched to identify studies reporting cases of APL during pregnancy. Sixty-six articles met the eligibility criteria (53 single case reports). Ninety-two patients were eligible for induction therapy, with most them being treated with all-trans retinoic acid alone (32%) or combined with chemotherapy (43%), while the remaining patients …
In vitroresponse toCandida albicansin cultures of whole human blood from young and aged donors
2007
Invasive infections with opportunistic fungi, such as Candida albicans, have become an increasing problem in aged adults in recent years. This work investigates the influence of human ageing on C. albicans recognition by toll-like receptors (TLRs), essential components of the innate immune system, using a cohort of 96 young (15-42 years) and aged (70 years) human volunteers. No significant differences between aged and young donors were observed on (1) cell surface TLR2, TLR6 and TLR4 expression on lymphocytes, monocytes and granulocytes, (2) production of cytokines [IL-8, IL-1beta, IL-6, IL-10, tumour necrosis factor (TNF)-alpha and IL-12p70] and prostaglandin E(2) (PGE(2)) by whole human b…
The influence of organizational factors on road transport safety
2018
Road transport safety is a major concern across Europe due to the human and socio-economic costs associated with work-related traffic accidents. Traditional approaches have adopted regulatory and technical measures to prevent road accidents leaving aside the organizational factors that might contribute to road transport safety. However, contemporary sociotechnical systems theory acknowledges the need to take into account organizational factors. This study adopts a sociotechnical approach and it examines the relationship between a number of organizational factors (organizational learning and training) and road traffic accidents in the organizations under study. Our sample was composed of 107…
Da Akrágas a Girgenti. Architettura e paesaggio nelle descrizioni e nell’iconografia della “città dei templi” fra Settecento e Ottocento
2016
Quando Gioacchino Di Marzo, intorno alla metà dell’Ottocento, intraprende l'opera di traduzione in italiano del Lexicon topograficum siculum di Vito Amico, dato alle stampe fra il 1757 e 1760, sente l'esigenza di dovere emendare incisivamente la voce dedicata alla città di Agrigento, in cui l'abate catanese aveva concesso alla città antica soltanto alcune brevi notazioni intorno ai templi antichi – fatta eccezione per il tempio di Giove Olimpico – soffermandosi invece sulla «novella Girgenti» e fornendo notizie dettagliate su tutti gli edifici degni di nota presenti nella città. Il tentativo di Di Marzo di colmare una simile lacuna – ingiustificabile a suo modo di vedere – scrivendo una lun…

National audience; La ville est un système très riche qui regroupe une multitude d’éléments en interactions les uns avec les autres. Elle peut être lue de diverses manières, et, selon le regard porté, révéler ses qualités politiques, culturelles, sociales... L’angle de vue que nous avons choisi pour ce travail est celui morphologique.
Development of a new indole derivative dry powder for inhalation for the treatment of biofilm-associated lung infections
2022
The aim of this work was to produce an inhalable dry powder formulation of a new anti-biofilm compound (SC38). For this purpose, chitosan was used as a polymeric carrier and l-leucine as a dispersibility enhancer. SC38 was entrapped by spray-drying into previously optimized chitosan microparticles. The final formulation was fully characterized in vitro in terms of particle morphology, particle size and distribution, flowability, aerodynamic properties, anti-biofilm activity and effects on lung cell viability. The SC38-loaded chitosan microparticles exhibited favorable aerodynamic properties with emitted and respirable fractions higher than 80 % and 45 % respectively. The optimized formulati…
