Different parts of the same plants. Charcoals and seeds from Cova de les Cendres (Alicante, Spain)
2018
Abstract The analysis of archaeobotanical macroremains from Cova de les Cendres (Teulada-Moraira, Alicante, Spain) allows a better understanding of the dynamic of the vegetation during the Upper Palaeolithic in the region. The anthracological sequence shows that Pinus type nigra/sylvestris dominates in the area during the Upper Palaeolithic, while more open formations of Juniperus and Fabaceae spread in Upper Solutrean and Early-Middle Magdalenian. The carpological analysis that has been carried out in the Middle Magdalenian level has brought to light different species of Juniperus (J. sabina, J. communis and J. oxycedrus). This information indicates that during the period, Cova de les Cend…
Silica Materials Containing Cyclodextrin for Pollutant Removal
2018
This chapter reviews the use of cyclodextrin-silica hybrid systems and cyclodextrin-functionalized silica used as adsorbents or filters for the removal of inorganic and organic pollutants from aqueous solutions in solid-phase extraction and adsorption-oriented processes. Actually, there is a need to develop efficient processes for the synthesis and application of multifunctional silica-based materials for pollutant removal by adsorption or filtration, and for sample purification and concentration using solid-phase extraction.
Hybrid Engagement: Discourses and Scenarios of Entrepreneurial Journalism
2018
Although the challenge posed by social media and the participatory turn concerns culture and values at the very heart of journalism, journalists have been reluctant to adopt participatory values and practices. To encourage audience participation and to offer journalism that is both trustworthy and engaging, journalists of the future may embrace a hybrid practice of journalistic objectivity and audience-centred dialogue. As innovative and experimental actors, entrepreneurial journalism outlets can perform as forerunners of such a culture. By analysing discourses in the “About Us” pages of 41 entrepreneurial journalism outlets, the article examines the emerging journalistic ethos of entrepren…
Global Geriatric Assessment and In-Hospital Bleeding Risk in Elderly Patients with Acute Coronary Syndromes: Insights from the LONGEVO-SCA Registry.
2018
Background: Bleeding risk scores have shown a limited predictive ability in elderly patients with acute coronary syndromes (ACS). No study explored the role of a comprehensive geriatric assessment to predict in-hospital bleeding in this clinical setting. Methods: The prospective multicentre LONGEVO-SCA registry included 532 unselected patients with non-ST segment elevation ACS (NSTEACS) aged 80 years or older. Comorbidity (Charlson index), frailty (FRAIL scale), disability (Barthel index and Lawton-Brody index), cognitive status (Pfeiffer test) and nutritional risk (mini nutritional assessment-short form test) were assessed during hospitalization. CRUSADE score was prospectively calculated …

Perioperative and Periprocedural Management of Antithrombotic Therapy: Consensus Document of SEC, SEDAR, SEACV, SECTCV, AEC, SECPRE, SEPD, SEGO, SEHH…
2018
During the last few years, the number of patients receiving anticoagulant and antiplatelet therapy has increased worldwide. Since this is a chronic treatment, patients receiving it can be expected to need some kind of surgery or intervention during their lifetime that may require treatment discontinuation. The decision to withdraw antithrombotic therapy depends on the patient's thrombotic risk versus hemorrhagic risk. Assessment of both factors will show the precise management of anticoagulant and antiplatelet therapy in these scenarios. The aim of this consensus document, coordinated by the Cardiovascular Thrombosis Working Group of the Spanish Society of Cardiology, and endorsed by most o…
Measurement of hadron form factors at BESIII
2018
The BESIII experiment, operated at the BEPCII e+e- collider in Beijing, has acquired large data sets at center-of-mass energies between 2.0 GeV and 4.6 GeV. One of the key aspects of the physics program of the BESIII collaboration is to test the understanding of QCD at intermediate energies. Applying different experimental techniques, form factors of hadrons are measured. Among these are the pion form factor, as an important input to the (g - 2)μ puzzle, and the electro-magnetic form factors of nucleons and hyperons in the time-like regime. An overview of the recent results and some ongoing studies at BESIII is provided.
Radial Glial Fibers Promote Neuronal Migration and Functional Recovery after Neonatal Brain Injury.
2018
Radial glia (RG) are embryonic neural stem cells (NSCs) that produce neuroblasts and provide fibers that act as a scaffold for neuroblast migration during embryonic development. Although they normally disappear soon after birth, here we found that RG fibers can persist in injured neonatal mouse brains and act as a scaffold for postnatal ventricular-subventricular zone (V-SVZ)-derived neuroblasts that migrate to the lesion site. This injury-induced maintenance of RG fibers has a limited time window during post-natal development and promotes directional saltatory movement of neuroblasts via N-cadherin-mediated cell-cell contacts that promote RhoA activation. Transplanting an N-cadherin-contai…
Effects of particle clustering on the plastic deformation and damage initiation of particulate reinforced composite utilizing X-ray CT data and finit…
2018
In this paper, a new simulation technique which can include microstructural inhomogeneity of particulate reinforced composites is proposed to accurately study deformation pattern and damage mechanism in these composites. Three dimensional microstructures constructed from XCT images incorporated into finite element modeling codes with minimal approximation to capture the effects of cluster size, local volume fraction of particles in the cluster and the distance between clusters as relevant statistical quantities describing the microstructural inhomogeneity of particulate reinforced composites. A quantitative parameter as degree of clustering is defined to consider particle clustering effect.…
Dislocated Temporalities : Immigration, Identity, and Sexuality in Najat El Hachmi?s «L?últim patriarca»
2018
Recent Catalan criticism has focused on place and space, as well as immigration, but has overlooked temporality. Yet migrations are not only a matter of space (of demographic movements and geographical relocations), but also of time: immigration questions the idea of origins and the possibility of a shared future, and problematizes the rhythms of everyday life. Temporality, in fact, is a key axis in the formation of identities and in cultural conflicts, not just regarding the uses of the past and the projection of societies towards the future, but also in relation to the normative uses of the body. The coexistence of asynchronous temporalities provoked by immigration is a factor in both cul…

Se espera que los mapas de entorno radio sean una herramienta esencial para la optimización y gestión de recursos del 5G en vehículos. En este trabajo, consideramos el problema de la reconstrucción del mapa de entorno radio utilizando una red de sensores inalámbricos formada por nodos sensores en vehículos, nodos de acceso de una infraestructura de ciudad inteligente, etc. Debido a las limitaciones de recursos en las redes de sensores, es crucial seleccionar un pequeño número de mediciones de los sensores para reconstruir el campo. En este contexto, presentamos un novedoso algoritmo distribuido basado en el método de regresión Kriging para la reconstrucción del mapa de entorno radio en térm…
Spanish Society of Hypertension position statement on the 2017 ACC/AHA hypertension guidelines
2018
The American College of Cardiology (ACC) and the American Heart Association (AHA) have recently published their guidelines for the prevention, detection, evaluation, and management of hypertension in adults. The most controversial issue is the classification threshold at 130/80 mmHg, which will allow a large number of patients to be diagnosed as hypertensive who were previously considered normotensive. Blood pressure (BP) is considered normal (<120 mmHg systolic and <80 mmHg diastolic), elevated (120-129 and <80 mmHg), stage 1 (130-139 or 80-89 mmHg), and stage 2 (≥140 or ≥90 mmHg). Out-of-office BP measurements are recommended to confirm the diagnosis of hypertension and for titra…
Consequences of Discontinuing Knowledge Work Automation – Surfacing of Deskilling Effects and Methods of Recovery
2018
IS automation pervades business processes today. Thus, concerns have been raised about automation’s potential deskilling effects on knowledge workers. We conduct a revelatory case study about an IT service firm where a managerial decision was taken to discontinue a fixed assets management (FAM) software that provided seemingly effective automation of fixed assets accounting and reporting. We study how automation can result in latent deskilling that later becomes apparent when the system gets discontinued, causing disruptions in employees’ daily work and organizational processes. We also investigate how the employees and the company recover from this disruption by leveraging various coping s…

2018
Objective: The aim of this study was to illustrate the characteristics of patients with palliative care (PC) needs, early identified by general practitioners (GPS), and to analyze their care process in home PC services. Background: Early identification and service integration are key components to providing quality palliative care (PC) services ensuring the best possible service for patients and their families. However, in Italy, PC is often provided only in the last phase of life and for oncological patients, with a fragmented service. Methods: Multicenter prospective observational study, lasting in total 18 months, implemented in a sample of Italian Home Palliative Care Units (HPCUs), enr…
Clauser-Horne-Shimony-Holt Bell inequality test in an optomechanical device
2018
We propose here a scheme, based on the measurement of quadrature phase coherence, aimed at testing the Clauser-Horne-Shimony-Holt Bell inequality in an optomechanical setting. Our setup is constituted by two optical cavities dispersively coupled to a common mechanical resonator. We show that it is possible to generate EPR-like correlations between the quadratures of the output fields of the two cavities, and, depending on the system parameters, to observe the violation of the Clauser-Horne-Shimony-Holt inequality.
The effect of an extra piece of fruit or vegetables at school on weight status in two generations - 14 years follow-up of the Fruit and Vegetables Ma…
2018
Background: The obesity epidemic presents a major public health challenge, and a poor diet quality has been identified as one of the most important contributing factors. Whereas a sufficient fruit and vegetable consumption has been associated with several positive health outcomes, the long-term effect on overweight and obesity is unclear. Thus, the aims of this study were to investigate if one year with free school fruit had any effect on weight status 14 years later, and if it affected the birth weight of the participants’ children. Methods: In 2001, 10 -12-year old Norwegian children, received one year of free school fruit in the intervention study “Fruits and Vegetables Make the Marks” (…
Fate of endocrine disruptor compounds in an anaerobic membrane bioreactor (AnMBR) coupled to an activated sludge reactor
2018
[EN] The occurrence and fate of three groups of micropollutants - alkylphenols, pentachlorophenol and hormones - were studied in a pilot plant consisting of an anaerobic membrane bioreactor (AnMBR) coupled to an activated sludge reactor (University of Cape Town configuration - UCT). Under anaerobic conditions, the octylphenol and technical-nonylphenol soluble concentrations increased producing negative degradation ratios (i.e., -175 and -118%, respectively). However, high 4-n-nonylphenol and bisphenol-A degradation ratios (92 and 59% for 4-n-nonylphenol and bisphenol-A, respectively) as well as complete pentachlorophenol, estrone, 17 beta-estradiol and 17 alpha-ethinylestradiol removal were…
Enhancing the extraction of laser-ionized beams from an arc discharge ion source volume
2018
© 2018 The Author(s) The Versatile Arc Discharge and Laser Ion Source (VADLIS) is a recently established ion source for the CERN-ISOLDE radioactive ion beam facility. It offers either electron-impact ionization (VADIS-mode) or resonance laser ionization (RILIS-mode). The choice of operating mode depends on the element of interest or the required beam purity. Particle-in-cell simulations using the VSim software show that the ion extraction efficiency of the VADLIS in RILIS-mode can be improved if it is equipped with an insulated extractor plate, to which an optimal voltage can be applied. This enables optimization of the RILIS-mode ion extraction independently of the electron density. Experi…
Statistical modeling, simulation, and experimental verification of wideband indoor mobile radio channel
2018
This paper focuses on the modeling, simulation, and experimental verification of wideband single-input single-output (SISO) mobile fading channels for indoor propagation environments. The indoor reference channel model is derived from a geometrical rectangle scattering model, which consists of an infinite number of scatterers. It is assumed that the scatterers are exponentially distributed over the two-dimensional (2D) horizontal plane of a rectangular room. Analytical expressions are derived for the probability density function (PDF) of the angle of arrival (AOA), the PDF of the propagation path length, the power delay profile (PDP), and the frequency correlation function (FCF). An efficie…
Absence of spatial genetic structure in common dentex (Dentex dentex Linnaeus, 1758) in the Mediterranean Sea as evidenced by nuclear and mitochondri…
2018
International audience; The common dentex, Dentex dentex, is a fish species which inhabits marine environments in the Mediterranean and Northeast Atlantic regions. This is an important species from an ecological, economic and conservation perspective, however critical information on its population genetic structure is lacking. Most samples were obtained from the Mediterranean Sea (17 sites) with an emphasis around Corsica (5 sites), plus one Atlantic Ocean site. This provided an opportunity to examine genetic structuring at local and broader scales to provide science based data for the management of fishing stocks in the region. Two mitochondrial regions were examined (D-loop and COI) along…

Measurement of emission-angle anisotropy via long-range angular correlations with high-pT hadrons in d+Au and p+p collisions at √sNN = 200 GeV
2018
We present measurements of two-particle angular correlations between high-transverse-momentum (2 < pT < 11 GeV/c) π0 observed at midrapidity (|η| < 0.35) and particles produced either at forward (3.1 <η< 3.9) or backward (−3.7 <η< −3.1) rapidity in d + Au and p + p collisions at √sNN = 200 GeV. The azimuthal angle correlations for particle pairs with this large rapidity gap in the Au-going direction exhibit a characteristic structure that persists up to pT ≈ 6 GeV/c and which strongly depends on collision centrality, which is a similar characteristic to the hydrodynamical particle flow in A + A collisions. The structure is absent in the d-going direction as well as in p + p collisions, in t…

2018
Kandidaatintutkielmani käsittelee äänenhuollon ja terveen äänenkäytön opetuksen paikkaa alakoulun musiikinopetuksessa. Ääniongelmat lasten keskuudessa ovat yleistymään päin, joten päätin lähteä tarkastelemaan ongelmien nousun syitä ja mahdollisia ehkäisykeinoja. Tarkastelen työssä vanhoja opetussuunnitelmia sekä uutta vuonna 2014 ilmestynyttä opetussuunnitelmaa ja tutkin, miten niissä opettajaa ohjataan kertomaan lapsille äänenmuodostuksesta. Esittelen työssä ihmisen äänenmuodostuselimistön ja sen, miten ääni niissä syntyy. Kerron yleisimmistä ääniongelmista niin lasten kuin aikuistenkin keskuudessa painottaen ongelmien syntyä ja oireita. Paneudun myöskin äänenhuollon opetuksen kulmakiviin …
Drivers’ experiences during floods : investigating the psychological influences underpinning decisions to avoid driving through floodwater
2018
A major risk factor for many flood-related drownings is driving through floodwater. We aimed to understand Australian drivers’ experiences and beliefs with respect to avoid driving through floodwater using the theory of planned behaviour as a framework. Study 1 (N = 23) used a qualitative design to gain an in-depth understanding of individuals’ experiences with driving through floodwater. Study 2 (N = 157) used a survey-based design to identify the factors related to this behaviour including knowledge, beliefs, and social-cognitive factors. In Study 1, drivers identified a range of advantages (e.g., didn’t damage car), disadvantages (e.g., inconvenient, but not so terrible), barriers (e.g.,…

Analyse av en muntlig og en digital vurdering i matematikk
2018
Masteroppgave matematikkdidaktikk MA502 – Universitetet i Agder 2018 The aim of this study is to analyze two different forms of assessment; an oral test and an assessment using the web-based program “Multi Smart Øving”. This study is based on the research question: How do the students express their knowledge through an oral and digital assessment in mathematics? In order to answer this, it was considered appropriate to split the research question into two questions. The first focuses on how one can relate an oral and digital assessment in mathematics to principles of “good assessment”. To answer this, the six criteria described by Engh, Dobson and Høihilder (2007) is used. The next question…
