New records of interesting xenophytes in the Iberian Peninsula
New records of interesting xenophytes in the Iberian Peninsula. Botanical inventories in various parts of Spain mainly between 2005 and 2007 yielded numerous chorological novelties.Cyperus prolifer is probably reported for the first time in Europe. Chenopodium simplex, Dactyloctenium aegyptium, Digitaria violascens, Eragrostis frankii, Ipomoea x leucantha, Ludwigia peploides subsp. montevidensis, Malvastrum coromandelianum, Melinis repens subsp. repens, Oenothera indecora subsp. indecora, Panicum philadelphicum subsp. gattingeri and Solanum americanum are probably recorded for the first time from Spain. Crassula campestris is first cited from Portugal. New provincial records include: Abutilon grandifolium (Barcelona), Amaranthus palmeri (Lérida), Amelichloa caudata (Valencia), Anoda cristata (Huelva), Arctotheca calendula (Gerona), Asparagus setaceus (Huelva), Bidens subalternans (Huelva), Cardiospermum halicacabum (Alicante), Cenchrus incertus (Cádiz), Cestrum parqui (Barcelona), Cyperus esculentus (Huelva), Datura ferox (Huelva), Elymus elongatus subsp. ponticus (Lérida, Sevilla), Eragrostis mexicana subsp.virescens (Huelva), Eragrostis pectinacea (Huelva), Galinsoga quadriradiata (Huelva), Hydrocotyle bonariensis (Huelva), Leptochloa uninervia (Granada, Huesca), Oenothera oehlkersi (Gerona), Rumex cristatus (Gerona), Senna obtusifolia (Huelva), Setaria faberi (Huelva), S. parviflora (Huelva), Solanum elaegnifolium (Alicante), S. linnaeanum (Granada), S. physalifolium (Huelva) and Verbena litoralis var. brevibracteata (Huelva). Previous Andalusian records of Galenia secunda turned out to be in error for G. pubescens. A large majority of the cited taxa is of American origin.Nuevas citas de xenófitos interesantes en la PenÃnsula Ibérica.

Se actualiza la nomenclatura en AndalucÃa de las citas previas del taxón Galenia secunda, que se cambia por Galenia pubescens, su nombre correcto. Una gran mayorÃa de los taxones citados son de origen americano
Bilateral Asymmetries Assessment in Elite and Sub-Elite Male Futsal Players
This study aimed to investigate morphological, functional, and neuromuscular asymmetries on futsal players’ lower limbs at different competitive levels. Sixteen male elite futsal players from the Spanish National Futsal League and thirteen male sub-elite futsal players from the third division participated in this study. Morphological asymmetry was assessed through bioelectrical impedance (fat-mass (g and %) and lean-mass (g)). Functional asymmetry was assessed by means of a 20-s static unipedal balance test. Finally, neuromuscular asymmetry was assessed using tensiomiography tests on both the rectus femoris (RF) and biceps femoris (BF) of each participant. The three tests conducted did not reveal significant bilateral asymmetries in elite players. On the other hand, sub-elite players showed significant bilateral asymmetry in fat-mass percentage between dominant and non-dominant limbs (+6%; CI95%: 1 to 11; ES: 0.88; p = 0.019). They also showed higher bilateral asymmetry in the delay time of the RF (+13%; CI95%: 7 to 21; ES: 1.3; p 0.05) did not evidence asymmetries regardless of the level of the participants. Elite futsal players do not develop bilateral asymmetries in lower limbs in the studied parameters. On the contrary, sub-elite players are likely to develop morphological and neuromuscular asymmetries between their dominant leg and non-dominant leg.Sin financiación3.390 JCR (2020) Q1, 42/176 Public, Environmental & Occupational Health0.747 SJR (2020) Q2, 50/136 Health, Toxicology and MutagenesisNo data IDR 2020UE
Themed issue on selected papers SEG2015: part II
This themed issue of Geomechanics for Energy and the Environment ‘SEG-2015-Part II’, presents papers selected from extended abstracts submitted to the Symposium on Energy Geotechnics (SEG-2015) held in the Civil Engineering School of the Universitat Politècnica de Catalunya in Barcelona, Spain, between June 2nd and 4th, 2015. This symposium SEG-2015 was the first event organized by the Technical Committee TC308 of the International Society for Soil Mechanics and Geotechnical Engineering, which will have continuity in the next symposium SEG-2018 to be held in the École Polytechnique Fédérale de Lausanne (Lausanne, Switzerland). The first issue ‘SEG-2015-Part I’ appeared just before the 1st International Conference on Energy Geotechnics (ICEG-2016), which was held in Kiel (Germany) at the end of August 2016. The second volume ‘SEG-2015-Part II’ on December 2016 will thus close a first cycle of successful conferences and publications along this
initial stage of TC308.Peer ReviewedPostprint (author's final draft
Development of methologies to study the damage tolerance of aeronautical and aerospace composite structures
Mechanics of Advanced Materials research group (Department of Continuum Mechanics and Structural Analysis) of the University Carlos III of Madrid (Spain) offers their experience in the analysis and modelization of high and low velocity impact behaviour and damage tolerance of composite structures
A hydrated ion model of [UO2]2+ in water: Structure, dynamics, and spectroscopy from classical molecular dynamics
A new ab initio interaction potential based on the hydrated ion concept has been developed to obtain
the structure, energetics, and dynamics of the hydration of uranyl in aqueous solution. It is the first
force field that explicitly parameterizes the interaction of the uranyl hydrate with bulk water molecules
to accurately define the second-shell behavior. The [UO2(H2O)5
]
2+
presents a first hydration shell
U–O average distance of 2.46 Å and a second hydration shell peak at 4.61 Å corresponding to 22
molecules using a coordination number definition based on a multisite solute cavity. The second
shell solvent molecules have longer mean residence times than those corresponding to the divalent
monatomic cations. The axial regions are relatively de-populated, lacking direct hydrogen bonding to
apical oxygens. Angle-solved radial distribution functions as well as the spatial distribution functions
show a strong anisotropy in the ion hydration. The [UO2(H2O)5
]
2+
solvent structure may be regarded
as a combination of a conventional second hydration shell in the equatorial and bridge regions, and
a clathrate-like low density region in the axial region. Translational diffusion coefficient, hydration
enthalpy, power spectra of the main vibrational modes, and the EXAFS spectrum simulated from
molecular dynamics trajectories agree fairly well with the experiment.Junta de AndalucÃa de España, Proyecto de Excelencia-P11-FQM 760
