Coverage, efficacy or dosing interval: which factor predominantly influences the impact of routine childhood vaccination for the prevention of varice…
2016
Background Varicella is a highly infectious disease with a significant public health and economic burden, which can be prevented with childhood routine varicella vaccination. Vaccination strategies differ by country. Some factors are known to play an important role (number of doses, coverage, dosing interval, efficacy and catch-up programmes), however, their relative impact on the reduction of varicella in the population remains unclear. This paper aims to help policy makers prioritise the critical factors to achieve the most successful vaccination programme with the available budget. Methods Scenarios assessed the impact of different vaccination strategies on reduction of varicella disease…
Vegetation growth parameters and leaf temperature: Experimental results from a six plots green roofs' system
2016
Abstract The paper provides a contribution for populating database of three physical parameters needed to model energy performance of buildings with green roofs: “coverage ratio” ( σ f ), leaf area index (LAI) and leaf temperature ( T f ). On purpose, six plant species were investigated experimentally: Phyla nordiflora, Aptenia lancifolia , Mesembryanthenum barbatus , Gazania nivea, Gazania uniflora , and Sedum . Proper ranges of the cited parameters have been found for each species. The here indicated ranges of σ f values refer to different growth levels of the species in the same lapse of time, that is four months. Single measured LAI values are also reported for the same plants. As for t…
Calcium Phosphate-Coated Titanium Implants in the Mandible: Limitations of the in vivo Minipig Model
2020
<b><i>Introduction:</i></b> We aimed to compare implant osseointegration with calcium phosphate (CaP) surfaces and rough subtractive-treated sandblasted/acid etched surfaces (SA) in an in vivo minipig mandible model. <b><i>Materials and Methods:</i></b> A total of 36 cylindrical press-fit implants with two different surfaces (CaP, <i>n</i> = 18; SA, <i>n</i> = 18) were inserted bilaterally into the mandible of 9 adult female minipigs. After 2, 4, and 8 weeks, we analyzed the cortical bone-to-implant contact (cBIC; %) and area coverage of bone-to-implant contact within representative bone chambers (aBIC; %). <b><…
Cement selection criteria for full coverage restorations: A comprehensive review of literature
2021
Background Proper cement selection in fixed prosthesis plays a determinative role in providing long-term serviceability, retention, caries prevention, and patient satisfaction. This study, reviews different luting agent characteristics and their application based on different clinical situations and different types of full coverage restorations. Material and methods An electronic search was conducted through PubMed, Medline, and Google scholar using following keywords or combinations: restoration, full coverage, PFM, porcelain fused to metal, all ceramic, zirconia, ceramic, casting, fixed partial denture, cement*, dental cement, cement selection, and retention.

Antibiotics and food in the American press
2021
AbstractThe emergence of antimicrobial resistant infections from food is well documented in the scientific literature but, in this kind of matter, the public opinion is an important policy driver and is vastly forged by traditional media. Here, we propose a text mining study through about 500 articles from two reference daily U.S. newspapers to assess the media coverage of this issue. Our results indicate that, since the middle of the 80s, the two journals considered here adopted a very different narrative around the issue, echoing civil society concerns in one case and the official discourse in the other.
La representación de la protesta contra Educación para la Ciudadanía en ABC y La Razón
2013
El objetivo de este trabajo es indagar en el tratamiento periodístico que recibió la protesta en contra de la asignatura Educación para la Ciudadanía por parte de los dos diarios ideológicamente más próximos a los impulsores de la controversia. El análisis se centra entre los años 2004 y 2008, periodo durante el que el conflicto en torno a esta materia fue más intenso. Para ello, realizamos un exhaustivo análisis de contenido de 650 piezas informativo-interpretativas. Los resultados señalan que la presentación negativa de la materia dominó en una cobertura cómplice con los críticos y escasamente explicativa. The aim of this work is to study the journalistic treatment that the protest agains…
La Crisis migratoria europea en El País e Izvestia: estudio ético y deontológico
2020
espanolEl objetivo de este estudio es analizar desde la perspectiva etica y deontologica la cobertura informativa de la crisis migratoria europea en las versiones digitales de los diarios El Pais (Espana) e Izvestia (Rusia). El estudio aborda textos informativos, se realiza en perspectiva sincronica, se basa en la revision de los principales documentos de referencia en el ambito a nivel nacional e internacional y combina las aproximaciones cuantitativa y cualitativa al analisis de contenido de la prensa. El analisis revela numerosos casos del incumplimiento de las normas eticas en ambos periodicos con significativas diferencias y similitudes a nivel cualitativo. EnglishThe objective of this…
Looking over the channel: The balance of media coverage about the “refugee crisis” in Germany and the UK
2022
Abstract This study compares the balance of newspaper and television news coverage about migration in two countries that were differently affected by the so-called “refugee crisis” in 2015 in terms of the geopolitical involvement and numbers of migrants being admitted. Based on a broad consensus among political elites, Germany left its borders open and received about one million migrants mainly from Syria during 2015. In contrast, the conservative British government was heavily attacked by oppositional parties for closing Britain’s borders and, thus, restricting immigration. These different initial situations led to remarkable differences between the news coverage in both countries. In line…
Cell Association With Load Balancing in Nonuniform Heterogeneous Cellular Networks: Coverage Probability and Rate Analysis
2017
To meet the ever-growing traffic demand and address the cell capacity shortage problem, associating end users to various tiers of cells in a multitier cellular network appears to be a promising approach. In this paper, we consider a nonuniform heterogeneous cellular network (NuHCN) and propose a cell association scheme that selectively mutes certain small-cell base stations (BSs) and covers end users by cell range extension (via cell biasing) for achieving load balancing. The envisaged NuHCN is comprised of two tiers of BSs, i.e., macro- and small-cell BSs, deployed according to three independent homogeneous Poisson point processes for BSs and end users, respectively. Accordingly, the avail…
Fault Injection into VHDL Models: Experimental Validation of a Fault-Tolerant Microcomputer System
1999
This work presents a campaign of fault injection to validate the dependability of a fault tolerant microcomputer system. The system is duplex with cold stand-by sparing, parity detection and a watchdog timer. The faults have been injected on a chip-level VHDL model, using an injection tool designed with this purpose. We have carried out a set of injection experiments (with 3000 injections each), injecting transient and permanent faults of types stuck-at, open-line and indetermination on both the signals and variables of the system, running a workload. We have analysed the pathology of the propagated errors, measured their latency, and calculated both detection and recovery coverage. We have…
