Grado de satisfacción y preferencias técnico-tácticas de jugadores de balonmano en etapas de formación según el sexo de los jugadores
Authors: García-Angulo A. , García-Angulo F. , Ortega Toro E. 
Published: May 2018

<p>Los objetivos del presente estudio son: a) analizar las preferencias técnico-tácticas de jugadores de balonmano, tanto en entrenamiento como en competición, diferenciando entre sexos; b) Saber cuáles son las acciones preferidas de los jugadores de balonmano diferenciando entre sexos; y c) diferenciar las situaciones de igualdad o desigualdad numérica de juego preferidas por los jugadores según el sexo del jugador. Se desarrolló un estudio de carácter selectivo sobre los jugadores de categoría infantil y cadete que participaron en el Campeonato de España de Balonmano por selecciones territoriales de 2012 (n=1015), diferenciando dos grupos: a) masculino y b) femenino. Se utilizó como instrumento el “Cuestionario de Satisfacción y Preferencias en Jugadores de Balonmano”. Los resultados más importantes mostraron que: a) La acción técnico-táctica favorita en ambos grupos es la de lanzar; b) La fase del juego favorita en ambos grupos es la de atacar; c) las chicas muestran una mayor preferencia por la defensa que los chicos; y d) Ciertas acciones defensivas ocasionan una gran satisfacción en ambos grupos, algo que se cree condicionado por lo que creen que les gusta y que piden sus entrenadores. Estos datos pueden servir para optimizar el proceso de enseñanza-aprendizaje del balonmano en chicos y chicas, entendiendo que sus preferencias no son las mismas.</p>

Published: May 2018

AbstractStructural design and modification are effective approaches to regulate the physicochemical properties of TiO2, which play an important role in achieving advanced materials. Herein, a plasma‐assisted method is reported to synthesize a surface‐defect‐rich and deep‐cation‐site‐rich S doped rutile TiO2 (R‐TiO2–x‐S) as an advanced anode for the Na ion battery. An amorphous shell (≈3 nm) is induced by the Ar/H2 plasma, which brings about the subsequent high S doping concentration (≈4.68 at%) and deep doping depth. Experimental results and density functional theory calculations demonstrate greatly facilitated ion diffusion, improved electronic conductivity, and an increased mobility rate of holes for R‐TiO2−x‐S, which result in superior rate capability (264.8 and 128.5 mAh g−1 at 50 and 10 000 mA g−1, respectively) and excellent cycling stability (almost 100% retention over 6500 cycles). Such improvements signify that plasma treatment offers an innovative and general approach toward designing advanced battery materials.
NIR‐Activated Polydopamine‐Coated Carrier‐Free “Nanobomb” for In Situ On‐Demand Drug Release

Published: May 2018

AbstractCarrier‐free nanoparticles with high drug loading have attracted increasing attention; however, in situ on‐demand drug release remains a challenge. Here, a novel near‐infrared (NIR) laser‐induced blasting carrier‐free nanodrug delivery system is designed and fabricated by coating doxorubicin (DOX) nanoparticles (DNPs) with a polydopamine film (PDA) that would prolong the blood circulation time of DNPs and avoid the preleakage of the DOX during blood circulation. Meanwhile, the NH4HCO3 is introduced to trigger in situ “bomb‐like” release of DOX for the production of carbon dioxide (CO2) and ammonia (NH3) gases driven by NIR irradiated photothermal effect of PDA. Both in vitro and in vivo studies demonstrate that the carrier‐free nanovectors with high drug loading efficiency (85.8%) prolong tumor accumulation, enhance chemotherapy, achieve the synergistic treatment of chemotherapy and photothermal treatment, and do not induce any foreign‐body reaction over a three‐week implantation. Hence, the delicate design opens a self‐assembly path to develop PDA‐based NIR‐responsive multifunctional carrier‐free nanoparticles for tumor therapy.

AbstractNicht iodierte Arene werden einfach und selektiv in einem Schritt unter milden Bedingungen in Diacetoxyiodarene überführt, wobei Iodtriacetate als Reagentien verwendet werden. Der oxidative Schritt ist von der Synthese hypervalenter Iod(III)‐Verbindungen entkoppelt, die nun ohne vorherige Reinigung bequem in einer Eintopfsynthese für Folgereaktionen hergestellt werden können. Die Chemie der Iodtriacetate wurde auch auf Heteroatomliganden ausgeweitet, um neuartige anorganische hypervalente Iodverbindungen herzustellen.
Thermal aging kinetic and effects on mechanical behavior of fully recycled composite based on polypropylene/polyethylene blend

Published: May 2018

ABSTRACTThe effect of thermal oxidation of a fully recycled carbon fibers reinforced stabilized polypropylene/polyethylene blend on the mechanical properties has been studied at 120, 130 and 140 °C. In a first step, several analyses by FTIR and UV spectrometry and differential scanning calorimetry were performed in order to detect and monitor the evolution of the antioxidants and oxidation products in the materials. This approach aims to well understand and identify the aging mechanisms that will be modeled in a second step in a kinetic model capable of predicting the evolution of carbonyl build‐up while taking into account the presence of the different antioxidants. Modeling results showed a good correlation between the kinetic behavior and the obtained experimental data. Furthermore, the effect of thermal aging on the mechanical behaviors of the composite and the matrix were studied at the macroscopic scale at different strain rates. It has been shown that the thermal oxidation affects only the elongation at break. The numerical values of the oxidation products generated by the kinetic model allowed linking the evolution of the mechanical behavior under aging with the physicochemical state of the material. © 2018 Wiley Periodicals, Inc.

Published: May 2018

Premise of the StudyTo enhance the understanding of the recent invasion process of the clonal waterweed Elodea nuttallii (Hydrocharitaceae), analyses of population structure and genotypic diversity need to be undertaken, for which genetic markers are needed.Methods and ResultsHigh‐throughput sequencing of DNA enriched for microsatellites was used to develop 24 loci that were characterized in E. nuttallii, 21 of which were polymorphic, with the number of alleles ranging from two to 10. In two populations, expected heterozygosity ranged among loci between zero and 0.796. In the congener E. canadensis, all markers yielded PCR products, 19 of which were polymorphic, with two to nine alleles and expected heterozygosity ranging from zero to 0.690 in two populations.ConclusionsThe markers described should be useful for future studies of population structure and clonal diversity of E. nuttallii as well as E. canadensis in their native and invasive range.

Published: May 2018

AbstractAn on‐line high‐performance liquid chromatography–biochemical detection (HPLC‐BCD) method, in which compounds separated by HPLC were on‐line reacted with enzyme and substrate solutions delivered by flow injection and the enzyme inhibition signal was collected by UV detection, was developed to rapidly screen α‐glucosidase inhibitors from green tea extracts in this study. The chromatographic fingerprints and enzyme inhibition profiles of the different brands of green tea could be simultaneously detected by the on‐line HPLC‐BCD method. Enzyme inhibition profiles were detected by the UV detector at 415 nm based on the reaction of α‐glucosidase and p‐nitrophenyl α‐d‐glucopyranoside (PNPG). PNPG (1.25 mm), α‐glucosidase (0.4 U/mL) and the flow rate 0.07 mL/min were applied as optimized parameters to detect α‐glucosidase inhibitors in green tea. Four components in green tea showed α‐glucosidase inhibition action and three of them were identified as HHDP‐galloyl glucose, (−)‐epigallocatechin‐3‐gallate and (−)‐epicatechin‐3‐gallate by HPLC–fourier‐transform mass spectrometry (HPLC‐FTMS). Two brands of green tea derived from Mengding and Enshi mountainous areas might be superior to the other samples in the prevention and treatment of diabetes owing to their stronger activities of enzyme inhibitors. The proposed on‐line HPLC‐BCD method could be used to rapidly identify the potential enzyme inhibitors in complex matrixes.

Published: May 2018

AbstractIn the last decade, 3D modeling techniques enjoyed a booming development in both hardware and software. High‐end hardware generates high fidelity results, but the cost is prohibitive, whereas consumer‐level devices generate plausible results for entertainment purposes but are not appropriate for medical uses. We present a cost‐effective and easy‐to‐use 3D body reconstruction system using consumer‐grade depth sensors, which provides reconstructed body shapes with a high degree of accuracy and reliability appropriate for medical applications. Our surface registration framework integrates the articulated motion assumption, global loop closure constraint, and a general as‐rigid‐as‐possible deformation model. To enhance the reconstruction quality, we propose a novel approach to accurately infer skeletal joints from anatomical data using multimodality registration. We further propose a supervised predictive model to infer the skeletal joints for arbitrary subjects independent from anatomical data reference. A rigorous validation test has been conducted on real subjects to evaluate the reconstruction accuracy and repeatability. Our system has the potential to make accurate body surface scanning systems readily available for medical professionals and the general public. The system can be used to obtain additional health data derived from 3D body shapes, such as the percentage of body fat.

Published: May 2018

AbstractObjectivesThe objective of this study was to review the characteristics of patients in cardiogenic shock treated with TandemHeart® percutaneous ventricular assist device (pVAD) to determine influential predictors of survival.BackgroundThe TandemHeart® pVAD is used in the management of patients with cardiogenic shock resulting from a variety of conditions. Several studies have documented the efficacy of this therapy and outlined its complications. Still, there is little data to guide the effective and appropriate use of this resource.MethodsPatients referred for TandemHeart® pVAD implant for refractory cardiogenic shock at the University of Virginia between September 2007 and October 2015 were retrospectively analyzed. Univariate analysis was used to identify predictors of mortality.ResultsFifty‐five patients underwent successful TandemHeart® implant. Hemodynamics significantly improved following TandemHeart® implant. Cardiac index increased from 1.8 ± 0.6 to 3.1 ± 1.0 L/min/m2 (P = 0.007) and pulmonary capillary wedge pressure decreased from 30. 5 ± 9.9 to 19.6 ± 7.4 mmHg (P =0.0007). Survival was significantly influenced by implant indication with 23.8% surviving in bridge to recovery vs. 51% in bridge to LVAD or surgery (P = 0.04). In patients who did not receive definitive therapy, only 4 (13.8%) were weaned from TandemHeart® support and survived to hospital discharge. Only younger age, 51.8 vs. 62.7 years, predicted survival to hospital discharge (P = 0.004).ConclusionMortality from refractory cardiogenic shock is high even with TandemHeart® support. Our study found that patients with an exit strategy with either cardiac surgery or durable LVAD implant significantly influenced survival to hospital discharge.

Published: May 2018

AbstractThe long noncoding RNAs MEG3 is involved in the pathogenesis and metastasis of cancer, which has been found to target the distal regulatory elements (DREs) of TGF‐β pathway genes TGFBR1, TGFB2, and SMAD2 by forming DNA‐RNA triplex. Here, the molecular mechanism of MEG3 binding to its cognate or noncognate DNA partners is investigated systematically via an integrative chemometric approach. Here, we apply a spatial information characterization technique to capture the structural and energetic features of DNA‐RNA triplex architecture and then to correlate the extracted features with binding potency of the triplex complexes. A genome‐wide statistical analysis strategy is used to quantitatively evaluate the intermolecular interaction between DNA with RNA in a high‐throughput manner. The strategy is then employed to examine the binding potency and recognition specificity of MEG3 with its interacting DRE partners TGFBR1, TGFB2, and SMAD2. As might be expected, the abundance of GA nucleotide residues in DNA core motif exhibits a positive correlation with the affinity of MEG3 binding to the DREs of TGF‐β pathway, while the MEG3 possesses a moderate specificity for its known cognate DNA partners on the background of numerous random decoys. Therefore, it is suggested that the MEG3 has a broad spectrum of potential targets in the human genome and may regulate diverse cell biological events.
Workforce Scheduling in Administrative Operations: A Case Study in Accounting
Authors: M. Miranda Douglas 
Published: May 2018

AbstractThis paper considers a case study of dynamic job scheduling applied to a real accounting operation. Tasks are assigned to agents over a time horizon minimizing the number of delays and overtime while maximizing the number of anticipated tasks. The solution respects a set of constraints such as agent skills, due time and precedence requirements. It also accounts for uncertainties by capturing changes in the environment such as new orders, changes in the agents' availability and unexpected problems while performing a task. The manager is given a chance to first simulate and then deploy corrective actions to mitigate the impact of changes in the environment. Two heuristics are developed and the results show a significant performance improvement in the operation. Copyright © 2018 ASAC. Published by John Wiley & Sons, Ltd.

Published: May 2018

AbstractRecently, diverse composites between carbon nanomaterials and conducting polymers have been intensively investigated for a variety of applications such as sensors and supercapacitors. These composites have been synthesized by either chemical or electrochemical methods, which have the drawbacks of using toxic oxidants or requiring complicated apparatus, respectively. The present study reports that the graphene oxide/polypyrrole (GO/PPy) composites can be easily synthesized in a single‐step catalyzed by horseradish peroxidase in an aqueous solution (pH 4.0). Scanning electron microscopy of the enzymatically synthesized GO/PPy composites shows that GO sheets are evenly coated with PPy without observable granular PPy particles. A symmetric two‐electrode coin cell capacitor (20 mm in diameter and 1.6 mm in thickness) was made to measure the electrical capacitance in an aqueous electrolyte (1 mol/L NaNO3) by the galvanostatic charge/discharge method. When the discharge current was 0.5 mA, the specific capacitance of the GO/PPy composites (46.6 F/g) was ∼390 times greater than graphene oxide (0.12 F/g) or ∼7 times greater than polypyrrole (6.7 F/g). Furthermore, the addition of a 0.2 L/L (20 vol%) water‐miscible ionic liquid, 1‐butyl‐3‐methylimidazolium tetrafluoroborate ([BMIM][BF4]), into the aqueous electrolyte enhanced the capacitance of the GO/PPy composites by 57 % at maximum.
Psychosocial roots of paranoid ideation: The role of childhood experiences, social comparison, submission, and shame

Published: May 2018

BackgroundSocial experiences have a significant impact on cognitive functioning and appraisals of social interactions. Specifically, recalls of antipathy from parents, submissiveness, and bullying during childhood can have a significant influence on paranoid ideation later in life.MethodMultiple hierarchical regression analysis was performed on a sample of 91 patients diagnosed with paranoid schizophrenia in remission and active phase, their first‐degree relatives (n = 32) and unaffected controls (n = 64).ObjectivesExploring the impact of distal (events from childhood) and proximal factors (current cognitive, emotional, and behavioural aspects of social functioning) in the frequency, degree of conviction, and distress resulting from paranoid ideation in the participants from 4 samples.ResultsProximal and distal factors (shame, submissive behaviour, negative social comparison, antipathy from father) predicted several aspects of paranoid ideation. Those variables had a differential impact in affected patients and healthy controls.DiscussionFinding suggests different variables being involved in paranoid ideation, and the specificities of patients with paranoid schizophrenia should be considered in the development of more effective psychotherapeutic interventions.
Irrigated areas grow faster than the population
Authors: Puy Arnald 
Published: May 2018

AbstractUnfolding regularities between population and irrigated agriculture might increase our capacity to predict their coevolution and better ensure food security and environmental welfare. Here I use three different data sets with detailed information at the national level for ~70% of the countries of Africa, Asia, the Americas, and Europe between 1950 and 2017 to show that irrigated areas might grow disproportionally for a given increase in population, e.g., with β > 1. The results are robust across continents, time series, population cut‐offs, and variations in the area accounted for irrigation by official institutions and independent scholars. This systematic pattern suggests the existence of an underlying law driving the growth rate of irrigated areas that transcends local particularities and can be well approximated by a power function of population, specially in the case of the Americas, Asia, and Europe. Nonlinearities derived from the open‐ended growth rate of irrigated areas should be taken into consideration when designing irrigation policies in order to avoid unexpected environmental costs.
Root functional change achieves water source separation under vegetation succession
Authors: Yamanaka Tsutomu 
Published: May 2018

AbstractWater source separation can be one of strategies for different plant species to coexist in a community. This study first demonstrates mechanisms of water source separation during vegetation succession. An isotope‐incorporated mechanistic model was employed to simulate the xylem water isotopic composition and the root water uptake profile for a Pinus densiflora–Quercus myrsinaefolia mixed stand undergoing secondary succession and a pure P. densiflora stand before succession. In the mixed stand, the model successfully simulated the xylem water isotopic composition on the assumption that the root surface resistance per unit length of root (rrs*) decreases with increasing depth for P. densiflora but is constant for Q. myrsinaefolia. Uptake fraction for P. densiflora was greater in deeper zones but in shallower for Q. myrsinaefolia. In contrast, in the pure stand, a constant rrs* for P. densiflora gave good reproducibility in isotope simulation and shallow water uptake dominated. These findings highlight root functional change as a mechanism of water source separation; pre‐existing P. densiflora trees decrease their deep‐root rrs* to compensate for an increase in shallow‐root rrs*. This mechanism was caused by competition against invading Q. myrsinaefolia trees.
