Risk factors and effectiveness of preventive measures against influenza in the community
2012
Please cite this paper as: Castilla et al. (2013) Risk factors and effectiveness of preventive measures against influenza in the community. Influenza and Other Respiratory Viruses 7(2) 177–183. Background The role of different risk exposures and preventive measures against influenza has not been well established. Objective The aim of this study was to evaluate risk factors and measures to prevent influenza infection in the community. Methods We conducted a multicenter case–control study. Cases were 481 outpatients aged 18 years or older with laboratory-confirmed influenza A(H1N1)09 in the 2009–2010 season in Spain. A control was selected for each case from outpatients from the same area …
Third-hand smoke exposure and health hazards in children
2013
Smoking still represents a huge public health problem. Millions of children suffer the detrimental effects of passive smoking. An increasing number of countries have recently issued laws to regulate smoking in public places. Instead, homes remain a site where children are dangerously exposed to environmental tobacco smoke (ETS). The combination of tobacco smoke pollutants which remain in an indoor environment, the so-called ‘third-hand smoke’ (THS), represent a new concept in the field of tobacco control. THS consists of pollutants that remain on surfaces and in dust after tobacco has been smoked, are re-emitted into the gas-phase, or react with other compounds in the environment to form se…
Round-handle decomposition ofS2×S1
2007
A round-handle decomposition is associated with a non-singular Morse–Smale flow on 3-manifolds prime to S 2× S 1. This decomposition has been built only for the 3-sphere S 3. In this paper we obtain the round-handle decomposition of non-singular Morse–Smale flows on S 2× S 1, in order to get all the different fattened round handles in this manifold. Some of them include non-separating boundary components that induce the topology of the links of periodic orbits.
A 21st century technique for food control: electronic noses.
2008
This work examines the main features of modern electronic noses (e-noses) and their most important applications in food control in this new century. The three components of an electronic nose (sample handling system, detection system, and data processing system) are described. Special attention is devoted to the promising mass spectrometry based e-noses, due to their advantages over the more classical gas sensors. Applications described include process monitoring, shelf-life investigation, freshness evaluation, authenticity assessment, as well as other general aspects of the utilization of electronic noses in food control. Finally, some interesting remarks concerning the strengths and weakn…
Sarcopenia reduces quality of life in the long-term: Longitudinal analyses from the English Longitudinal Study of Ageing
2022
Abstract Purpose Mixed findings exist for sarcopenia/quality of life (QoL) relationship. Moreover, the majority of studies in this area have utilized a cross-sectional design or specific clinical populations. Therefore, the aim of the present study was to examine the association between sarcopenia at baseline and QoL at 10 years follow-up in a large representative sample of older English adults. Methods Sarcopenia was diagnosed as having low handgrip strength and low skeletal muscle mass index. QoL was measured using the CASP (control, autonomy, self-realisation and pleasure)-19, with higher values reflecting higher QoL. Multivariable logistic regression analysis was conducted to assess pro…
String dynamics and metastability of fully-heavy tetraquarks
2017
Multiquark states have been advocated to explain recent experimental data in the heavy-light sector, and there are already speculations about multiquarks containing only heavy quarks and antiquarks. With a rigorous treatment of the four-body problem in current quark models, full-charm $(cc\bar c\bar c)$ and full-beauty $(bb\bar b\bar b)$ tetraquarks are found to be unbound. Thus their stability should rely on more subtle effects that are not included in the simple picture of constituent quarks. The case of $(bc\bar b\bar c)$ might be more favorable if the naive color-additive model of confinement is replaced by a string-inspired interaction.
3D modul for syntetisk kalkulator
2006
Masteroppgave i informasjons- og kommunikasjonsteknologi 2006 - Høgskolen i Agder, Grimstad ActionScript er et språk som har blitt benyttet mer og mer de senere årene og er en del av verktøyet Flash. Dette er et design verktøy som har gode metoder for animasjoner i 2D og genererer små filer som gjør det svært egnet for internett. Denne rapporten ser på mulighetene for å generere, håndtere og visualisere tredimensjonale objekter i Flash ved bruk av ActionScript. Det blir diskutert roteringsmatriser opp mot Quaternion rotasjon og isometrisk projeksjon opp mot perspektivisk projeksjon i forhold til 3D objekter. Rapporten tar for seg ulike kurver og flater og hvilke begrensninger ActionScript h…
Use of selected autochthonous lactic acid bacteria for Spanish-style table olive fermentation
2012
The present work presents a successful attempt to achieve an enhanced and more predictable fermentation process in Spanish-style green olive technology by selection and use of autochthonous starter cultures. During the first phase of this work, two Spanish-like fermentations of green table olives of cultivar (cv) “Nocellara del Belice”, coming from irrigated and not irrigated fields, were monitored, in order to highlight the best agricultural conditions for drupe production and to isolate lactic acid bacteria strains with relevant technological properties. Among 88 identified isolates, one Lactobacillus pentosus strain showed remarkable biochemical features and high acidification rate in sy…

Conformational preferences and synthesis of isomers Z and E of oxazole-dehydrophenylalanine
2016
Dehydrophenylalanine, ΔPhe, is the most commonly studied α,β-dehydroamino acid. In nature, further modifications of the α,β-dehydroamino acids were found, for example, replacement of the C-terminal amide group by oxazole ring. The conformational properties of oxazole-dehydrophenylalanine residue (ΔPhe-Ozl), both isomers Z and E, were investigated. To determine all possible conformations, theoretical calculations were performed using Ac-(Z/E)-ΔPhe-Ozl(4-Me) model compounds at M06-2X/6-31++G(d,p) level of theory. Ac-(Z/E)-ΔPhe-Ozl-4-COOEt compounds were synthesized and the conformational preferences of each isomer, Z and E, were investigated using FTIR and NMR-NOE in solutions of increasing p…
