Influence of the structural components of artificial turf systems on impact attenuation in amateur football players
2019
AbstractThe purpose of this research was to evaluate the influence of the structural components of different 3rd generation artificial turf football field systems on the biomechanical response of impact attenuation in amateur football players. A total of 12 amateur football players (24.3 ± 3.7 years, 73.5 ± 5.5 kg, 178.3 ± 4.1 cm and 13.7 ± 4.3 years of sport experience) were evaluated on three third generation artificial turf systems (ATS) with different structural components. ATS were composed of asphalt sub-base and 45 mm of fibre height with (ATS1) and without (ATS2) elastic layer or compacted granular sub-base, 60 mm of fibre height without elastic layer (ATS3). Two triaxial accelerome…
Basal metabolic rate in narcoleptic patients.
2009
PATIENTS SUFFERING FROM NARCOLEPSY TEND TO BE OBESE.1,2 AMONG OTHER HYPOTHESES LOWER RESTING ENERGY EXPENDITURE HAS BEEN SUSPECTED to be the cause of the narcolepsy-associated obesity.3,4 The use of indirect calorimetry is a well-established noninvasive method to measure the energy expenditure (EE) and the resting (basal) metabolic rate (BMR). Chabas et al. recently published an evaluation of eating behavior and energy balance of 7 typical and 6 atypical narcoleptic patients and 9 controls using indirect calorimetry. Narcoleptic patients were found to have a lower energy expenditure (EE) than controls (n = 13, P = 0.07). Thus, it was concluded that narcolepsy associated obesity could be the…
COOLING OF COMMERCIAL BUILDINGS BY MEANS OF LARGE COLD RADIANT CEILINGS
1991
ABSTRACT The possibility of using different cooling tools working with lower radiant temperatures and higher air velocity is explored. Lower energy consumptions may be achieved in specific climates with reasonable levels of thermal comfort.
Microesferas de ácido poliláctico marcadas con 166Ho. Una alternativa frente a las de 90Y en el tratamiento del carcinoma hepático mediante radioembo…
2021
Los tumores hepáticos constituyen un importante problema de salud a nivel mundial que en multitud de ocasiones va asociado a patologías previas y factores de riesgo como las hepatitis víricas B y C, el consumo excesivo de alcohol y el aumento de casos de esteatohepatitis no alcohólica, cada vez más relevante en los países industrializados.En hepatocarcinomas no susceptibles de resección quirúrgica, la braquiterapia se está mostrando muy eficaz frente a la quimioterapia sistémica y transarterial, por lo que se desarrollan nuevos tratamientos locorregionales mínimamente invasivos y con menor toxicidad.La radioembolización hepática es una forma de braquiterapia consistente en la administración…
Innovative “Green” and Novel Strategies for the Extraction of Bioactive Added Value Compounds from Citrus Wastes—A Review
2017
Citrus is a major processed crop that results in large quantities of wastes and by-products rich in various bioactive compounds such as pectins, water soluble and insoluble antioxidants and essential oils. While some of those wastes are currently valorised by various technologies (yet most are discarded or used for feed), effective, non-toxic and profitable extraction strategies could further significantly promote the valorisation and provide both increased profits and high quality bioactives. The present review will describe and summarize the latest works concerning novel and greener methods for valorisation of citrus by-products. The outcomes and effectiveness of those technologies such a…
Life Cycle Assessment (LCA) of protected crops: an Italian case study
2012
Abstract In this paper a Life Cycle Assessment (LCA) of protected crops was carried out. In particular, energy and environmental performances of peppers, melons, tomatoes, cherry tomatoes, and zucchini in different typologies of greenhouses (tunnel and pavilion) were assessed. The study aimed at assessing the ecoprofile of each product and the share of each life-cycle step on the total environmental impacts. The related process flow chart, the relevant mass and energy flows and the key environmental issues were identified for each product. Collection of primary data was conducted by means of a detailed questionnaire distributed to a producer company in southern Italy. The analysis was devel…
Centrality, rapidity and transverse momentum dependence of J/ψ suppression in Pb–Pb collisions at sNN=2.76 TeV
2014
The inclusive J/.nuclear modification factor (R-AA) in Pb-Pb collisions at root(NN)-N-S = 2.76TeVhas been measured by ALICE as a function of centrality in the e+ e-decay channel at mid-rapidity (| y| < 0.8) and as a function of centrality, transverse momentum and rapidity in the + -decay channel at forward-rapidity (2.5 < y < 4). The J/.yields measured in Pb-Pb are suppressed compared to those in ppcollisions scaled by the number of binary collisions. The RAAintegrated over a centrality range corresponding to 90% of the inelastic Pb-Pb cross section is 0.72 - 0.06(stat.) - 0.10(syst.) at mid-rapidity and 0.58 - 0.01(stat.) - 0.09(syst.) at forward-rapidity. At low transverse momentum, signi…
On the photoelectron spectrum ofp-benzoquinone
2001
A high-resolution photoelectron spectrum of p-benzoquinone in the low energy (9.5–11.5 eV) region is reported and analyzed with the aid of simulations based on high-level ab initio calculations. The results generally support the notion that the two prominent spectral features in this region are each due to a pair of final ion states. The lower energy feature beginning near 10 eV is due to oxygen lone-pair ionizations, while that beginning near 11 eV comes from π electron removal. Contrary to previous interpretations of the spectrum, however, the results of this study indicate that the two π states are nearly degenerate, with the strongest peak in the photoelectron spectrum representing a co…
Quantum beats from dressed three-level atoms
1983
Abstract By extending a previously developed unitary transformation technique to dress three-level atoms by a strong driving radiation field, we show that quantum beats can be induced by the presence of the driving field also when the decay channels lead from a singlet to a doublet of lower energy. A qualitative explanation of this effect is presented, which is based on the quantum theory of measurement.
Υ(1S+2S+3S)production ind+Au andp+pcollisions atsNN=200GeV and cold-nuclear-matter effects
2013
The three gamma states, gamma (1S + 2S + 3S), are measured in d + Au and p + p collisions at root s(NN) = 200 GeV and rapidities 1.2 < vertical bar y vertical bar < 2.2 by the PHENIX experiment at the Relativistic Heavy Ion Collider. Cross sections for the inclusive gamma (1S + 2S + 3S) production are obtained. The inclusive yields per binary collision for d + Au collisions relative to those in p + p collisions (R-dAu) are found to be 0.62 +/- 0.26 (stat) +/- 0.13 (syst) in the gold-going direction and 0.91 +/- 0.33 (stat) +/- 0.16 (syst) in the deuteron-going direction. The measured results are compared to a nuclear-shadowing model, EPS09 [Eskola et al., J. High Energy Phys. 04 (2009) 065]…
