Deíxis y contacto en la región del Gran Chaco: Los demostrativos en las lenguas guaycurúes y mataguayas
Authors: Messineo Cristina , Carol Javier , Klein Harriet E. Manelis 
Published: May 2016

ResumenLas lenguas guaycurúes y mataguayas (Gran Chaco) constituyen casos interesantes y tipológicamente inusuales por la complejidad de sus sistemas de demostrativos que combinan deíxis espacial con rasgos como visibilidad, tangibilidad, movimiento, postura y evidencia (visual). Sistemas similares han sido hallados en otras lenguas del mundo, aunque la combinación de estos con postura y/o movimiento es atípica.En la familia guaycurú los demostrativos, además de cumplir la función de determinantes, son clasificadores nominales. Esta característica, en cambio, no es del todo compartida por las lenguas mataguayas. En las lenguas de ambas familias los demostrativos contribuyen también al señalamiento pragmático del tiempo, el modo y la evidencialidad, no necesariamente codificados en el predicado.El trabajo muestra las semejanzas entre los sistemas de ambas familias y propone que ellas no pueden explicarse por causas universales o mera coincidencia, sino que el contacto juega allí un papel importante. Por otra parte, aun cuando la hipótesis de una relación genética entre ambas familias sea razonable, esta no parece suficiente para explicar las similitudes en los sistemas de demostrativos, que van más allá de las formas presumiblemente cognadas.

On the q-Bernstein polynomials of the logarithmic function in the case q > 1
Authors: Ostrovska Sofiya 
Published: May 2016

Abstract
The q-Bernstein basis used to construct the q-Bernstein polynomials is an extension of the Bernstein basis related to the q-binomial probability distribution. This distribution plays a profound role in the q-boson operator calculus. In the case q > 1, q-Bernstein basic polynomials on [0, 1] combine the fast increase in magnitude with sign oscillations. This seriously complicates the study of q-Bernstein polynomials in the case of q > 1.
The aim of this paper is to present new results related to the q-Bernstein polynomials Bn

q
of discontinuous functions in the case q > 1. The behavior of polynomials Bn

Solutions and constrained null-controllability for a differential-difference equation
Authors: Iakovleva Valentina , Manzanilla Raúl , Mármol Luis Gerardo , Vanegas Carmen J. 
Published: May 2016

Abstract
A formula for the solution of a differential-difference equation is given, and then the corresponding semigroup theory is developed, with a detailed description of the infinitesimal generator and some of its spectral properties.
Results in Sections 2 and 3 are used in particular to show how the equation can be rewritten as a classical Cauchy problem. This, in Section 4, allows to study its exact null-controllability, by using some techniques from Functional Analysis and Operator Theory. The control u is constrained to lie in a separable weakly compact subset Ω of an arbitrary Banach space U.
Non-linear dynamic response and vibration of an imperfect three-phase laminated nanocomposite cylindrical panel resting on elastic foundations in thermal environments
Authors: Thu Pham Van , Duc Nguyen Dinh 
Published: May 2016

Abstract
This paper presents an analytical approach to investigate the non-linear dynamic response and vibration of an imperfect three-phase laminated nanocomposite cylindrical panel resting on elastic foundations in thermal environments. Based on the classical laminated shell theory and stress function, taking into account geometrical non-linearity, initial geometrical imperfection, Pasternak-type elastic foundation, and temperature, the governing equations of the three-phase laminated nanocomposite cylindrical panel are derived. The numerical results for the dynamic response and vibration of the polymer nanocomposite cylindrical panel are obtained by using the Runge-Kutta method. The influences of fibres and nanoparticles, different fibre angles, material and geometrical properties, imperfection, elastic foundations, and temperature on the non-linear dynamic response of the polymer nanocomposite cylindrical panel are discussed in detail.
Crystal structures and vibrational spectra of biuret co-crystals with cyanuric and glutaric acids, discussion of hydrogen bonding involving carbonyl groups

Abstract
The title structures of biuret-cyanuric acid (2/2) monohydrate, C10H18N12O11, 1 [P1̅, Z=2, a=8.2598(4) Å, b=10.8795(5) Å, c=11.9138(6) Å, α=67.036(1)°, β= 79.842(2)°, γ=69.859(2)°, V=924.38(8) Å3], and of biuret-glutaric acid (1/1), C7H13N3O6, 2 [P1̅, Z=2, a=5.0044(3) Å, b=7.0832(3) Å, c=14.9803(10) Å, α=102.860(4)°, β= 91.899(3)°, γ=102.202(4)°, V=504.20(5) Å3], show usual features both in constitution and intermolecular contacts except for a slightly longer C=O bond length in one of the carbonyl groups in 2. The biuret molecules have conformations with anti-parallel arrangement of the carbonyl groups. In each structure O–H…O and N–H…O hydrogen bonds of the moderate strength are present. The new results are compared with other structures which contain biuret molecules. The influence of the hydrogen bonding on the bond length of the carbonyl group C=O in the fragment NH2-(C=O)-NH with amine and hydroxyl donors has also been investigated. It transpires that the C=O…H angle of about 120° favors a slight elongation of the C=O bond length. The elongation of the C=O bond is more susceptible to the relative orientation of the C=O group with regard to amine over hydroxyl groups. This is the likely explanation why one of the C=O bonds in 2 is slightly longer than usual because this carbonyl group is simultaneously involved in two hydrogen bonds where C=O…H–O and C=O…H–N satisfy the 120° condition. Vibrational spectra of the title structures were also recorded and assigned.
Reverse Atom Transfer Radical Polymerization of Styrene in the Presence of Functionalized Silica Aerogel Nanoparticles
Authors: Khezri Khezrollah , Mahdavi Hossein 
Published: May 2016

Abstract
Pristine silica aerogel nanoparticles surface was functionalized with 3-(trimethoxysilyl)propyl methacrylate
(MPS). Then, the resultant functionalized nanoparticles were used in grafting through polymerization of styrene by reverse
initiation technique for atom transfer radical polymerization. Nitrogen adsorption/desorption isotherm is applied to
examine surface area and structural characteristics of the synthesized nanoparticles. Evaluation of size distribution and
morphological studies were also performed by scanning and transmission electron microscopy. Conversion and molecular
weight determinations were carried out using gas and size exclusion chromatography respectively. Addition of
MPS-functionalized nanoparticles by 3 wt % results in a decrease of conversion from 98 to
81%. Molecular weight (M
n) of the free polystyrene chains decreases by adding 3 wt %
modified silica aerogel nanoparticles; however, polydispersity index (PDI) values increases from 1.31 to
1.92. Although PDI values of attached polystyrene chains are increased, M
n values reveal an increment by
adding silica aerogel nanoparticles. A peak around 4.1 ppm which originates from hydrogen atom of terminal
units of polystyrene chains in proton nuclear magnetic resonance spectra can demonstrate the living nature of the
polymerization. Increasing thermal stability of the nanocomposites is demonstrated by TGA. Differential scanning
calorimetry also shows a decrease in glass transition temperature by increasing modified silica aerogel nanoparticles.

mixture. Also the thermal stability factor of the different liquid crystal phases is discussed.
Pitting Corrosion of Zn Peculiarly Caused by Acetate Anions
Authors: Abdel-Samad Hesham S. , Hassan Hamdy H. 
Published: May 2016

Abstract
The corrosion behaviour of zinc metal was studied in acetate solutions. The potentiodynamic polarization curve in
0.1 M acetate solution displays an anodic peak (A1) owing to the anodic dissolution of zinc followed by
a passive layer formation region. Breakdown of the passive film and the initiation of pitting corrosion were observed
beyond the pitting potential (E
pit) and confirmed by SEM images. The reverse scan of the cyclic voltammogram shows
three cathodic peaks; CI, CII and CIII. CI was attributed to the reduction of the pitting corrosion product formed at
potentials more anodic than E
pit, while the overlapped CII and CIII peaks were attributed to the reduction of the
exterior and the interior passive layers, respectively. The potentiostatic current time transients at different applied
potentials (around the pitting potential) for different electrolyte concentrations involved three stages. The first stage
exhibited rapid current decrease with time till a minimum value (i
m) at the incubation time
(t
i). The second and the third stages, where the current increases again linearly with time through two
different slopes, are correlated to the pit nucleation and growth, respectively. An increase of the pit nucleation rate
and a decrease in its growth were observed with increasing the anodic potential limit (E
a). Electrochemical impedance
spectroscopy (EIS) measurements, at different potentials before and after E
pit were performed. The effect of the
acetate concentration was studied as well. A suggested equivalent circuit was used to fit the EIS data. The impedance
results confirmed that the thickness of the formed passive layer increases with proceeding of the anodic potential
reaching a maximum value at E
pit. The passive film thickness decreased again at more anodic potentials.
Functional Indicators of Glutamate Transport in Single Striatal Astrocytes and the Influence of Kir4.1 in Normal and Huntington Mice
Authors: Dvorzhak Anton , Vagner Tatyana , Kirmse Knut , Grantyn Rosemarie 
Published: May 2016

This study evaluates single-cell indicators of glutamate transport in sulforhodamine 101-positive astrocytes of Q175 mice, a knock-in model of Huntington's disease (HD). Transport-related fluorescent ratio signals obtained with sodium-binding benzofuran isophtalate (SBFI) AM from unperturbed or voltage-clamped astrocytes and respective glutamate transporter currents (GTCs) were induced by photolytic or synaptic glutamate release and isolated pharmacologically. The HD-induced deficit ranged from −27% (GTC maximum at −100 mV in Ba2+) to −41% (sodium transients in astrocytes after loading SBFI-AM). Our specific aim was to clarify the mechanism(s) by which Kir4.1 channels can influence glutamate transport, as determined by either Na+imaging or transport-associated electrical signals. A decrease of Kir4.1 conductance was mimicked with Ba2+(200 μm), and an increase of Kir4.1 expression was obtained by intravenous administration of AAV9–gfaABC1D–Kir4.1–EGFP. The decrease of Kir4.1 conductance reduced the sodium transients but increased the amplitudes of somatic GTCs. Accordingly, after genetic upregulation of Kir4.1, somatic GTCs were found to be decreased. In individual cells, there was a negative correlation between Kir4.1 currents and GTCs. The relative effect of the Kir4.1 conductance was higher in the astrocyte periphery. These and other results suggest that the Kir4.1 conductance affects glutamate transporter activity in a dual manner: (1) by providing the driving force (voltage dependency of the transport itself) and (2) by limiting the lateral charge transfer (thereby reducing the interference with other electrogenic transporter functions). This leads to the testable prediction that restoring the high conductance state of passive astrocytes will not only normalize glutamate uptake but also restore other astrocytic transporter activities afflicted with HD.SIGNIFICANCE STATEMENTInsufficiency of astrocytic glutamate uptake is a major element in the pathophysiology of neurodegenerative diseases. Considering the heterogeneity of astrocytes and their differential susceptibility to therapeutic interventions, it becomes necessary to evaluate the determinants of transport activity in individual astroglial cells. We have examined intracellular Na+transients and glutamate transporter currents as the most telling indicators of glutamate clearance after synaptic or photolytic release of glutamate in striatal slices. The results show that, in Huntington's disease, glutamate uptake activity critically depends on Kir4.1. These channels enable the high conductance state of the astrocytic plasma membrane, which ensures the driving force for glutamate transport and dumps the transport-associated depolarization along the astrocyte processes. This has significant implications for developing therapeutic targets.
Prolonged Type 1 Metabotropic Glutamate Receptor Dependent Synaptic Signaling Contributes to Spino-Cerebellar Ataxia Type 1
Authors: Power Emmet M. , Morales Adrienne , Empson Ruth M. 
Published: May 2016

Type 1 metabotropic glutamate receptor (mGluR1)-dependent signaling at parallel fiber to Purkinje neuron synapses is critical for cerebellar function. In a mouse model of human spino-cerebellar ataxia type 1 (early SCA1, 12 weeks) we find prolonged parallel fiber mGluR1-dependent synaptic currents and calcium signaling. Acute treatment with a low dose of the potent and specific activity-dependent mGluR1-negative allosteric modulator JNJ16259685 shortened the prolonged mGluR1 currents and rescued the moderate ataxia. Our results provide exciting new momentum for developing mGluR1-based pharmacology to treat ataxia.SIGNIFICANCE STATEMENTAtaxia is a progressive and devastating degenerative movement disorder commonly associated with loss of cerebellar function and with no known cure. In the early stages of a mouse model of human spinocerebellar ataxia type 1, SCA1, where mice exhibit only moderate motor impairment, we detect excess “gain of function” of metabotropic glutamate receptor signaling at an important cerebellar synapse. Because careful control of this type of signaling is critical for cerebellar function in mice and humans, we sought to remove the excess signaling with a powerful, readily available pharmacological modulator. Remarkably, this pharmacological treatment acutely restored normal motor function in the ataxic mice. Our results pave the way for exploring a new avenue for early treatment of human ataxias.

Published: May 2016

In the educational process it is necessary to use management paradigms and active participation of parents. The objective was to determine the use of management strategies by the director of basic education and participation of parents in the educational process. It is a descriptive, transversal and field study, whose instrument was a questionnaire of 26 closed-questions. The sample comprised 16 directors, 52 teachers and 62 parents. For most managers and faculty the technique of brainstorming, involvement in decision-making, continues knowledge management and radical change are crucial in the educational process of children. But mothers and fathers believe that managerial groups do not use strategies properly except for reengineering. The mother and fathers are mainly involved in education management but not in the learning process. It is recommended the deepening of policy management training teaching force, through continuous training provided by the government and the promotion of family participation in the teaching-learning process of children.
Repercusiones del consumismo en el proyecto de vida: Un análisis desde la educación ciudadana
Authors: Ramírez-Díaz Jose Laurian 
Published: May 2016

Nowadays, work is being considered a social fact through which people satisfy different types of needs. However, some lines of thought proposed consumption as sole mediator to achieve happiness, which promotes poor scenarios where some people jeopardize their health and integrity with excessive practices such as consumerism, causing effects of different nature such as environmental damage and alienation of the project of life. Civic education is facing major challenges regarding the inclusion of critical thinking in advertising messages, effective decision making, environmental conservation and protection, imitation of social models in a conscious way and appropriate stewardship. This essay aims to treat these lines based on different theoretical edges concerning the human being concept and development; so they constitute training process criteria for analysis in different contexts, especially educational, whereas one of the Ministry of Public Education action policies is, precisely, civic training.

Published: May 2016

This study establishes three objectives. The first, describe the main characteristics of a tutorial action program developed within an academic subject in a Faculty of teacher training. The second, determine the level of appraisement of the degree of importance given by students to a group of transversal skills and the kowledge level related to the research methodology during the tutorial action. The third, discuss the role of the tutorial action at the university in the new European Higher Education Area. The experience was developed in the academic year 2014-2015. Thirty six students participated and constructed two ad-hoc questionnaires. Four elements can be highlighted from the analysis of results: the interaction between participants, the perceived organization and the tutorial action methodology, the positive assessment to the development of skills related to research, and the development of critical attitude. As conclusion, it is considered that showing the process of construction and development of the tutorial action as an alternative experience in higher education and teacher training subjects, can help to clarify alternative pedagogical mechanisms to facilitate communication and participatory processes consistent with the new European Higher Education Area.

Published: May 2016

BACKGROUND:
Infants &lt;6 months old with influenza are at risk for adverse outcomes. Our objective was to compare influenza outcomes in infants &lt;6 months old born to women who did and did not report influenza vaccine during pregnancy.

METHODS:
The study included all women who delivered from 12/2005 to 3/2014 at Intermountain facilities and their infants. Influenza outcomes included infant influenza-like illness (ILI), laboratory-confirmed influenza, and influenza hospitalizations.

RESULTS:
The cohort included 245 386 women and 249 387 infants. Overall, 23 383 (10%) pregnant women reported influenza immunization. This number increased from 2.2% before the H1N1 pandemic to 21% postpandemic (P &lt; .001). A total of 866 infants &lt;6 months old had ≥1 ILI encounter: 32 (1.34/1000) infants born to women reporting immunization and 834 (3.70/1000) born to women who did not report immunization (relative risk [RR] 0.36; 95% confidence interval [CI], 0.26–0.52; P &lt; .001). A total of 658 infants had laboratory-confirmed influenza: 20 (0.84/1000) born to women reporting immunization and 638 (2.83/1000) born to unimmunized women (RR 0.30; 95% CI, 0.19–0.46; P &lt; .001). A total of 151 infants with laboratory-confirmed influenza were hospitalized: 3 (0.13/1000) born to women reporting immunization and 148 (0.66/1000) born to unimmunized women (RR 0.19; 95% CI, 0.06–0.60; P = .005).

CONCLUSIONS:
Self-reported influenza immunization during pregnancy was low but increased after the H1N1 pandemic. Infants born to women reporting influenza immunization during pregnancy had risk reductions of 64% for ILI, 70% for laboratory-confirmed influenza, and 81% for influenza hospitalizations in their first 6 months. Maternal influenza immunization during pregnancy is a public health priority.

OBJECTIVE:
To determine if multiple doses of erythropoietin (Epo) administered with hypothermia improve neuroradiographic and short-term outcomes of newborns with hypoxic-ischemic encephalopathy.

METHODS:
In a phase II double-blinded, placebo-controlled trial, we randomized newborns to receive Epo (1000 U/kg intravenously; n = 24) or placebo (n = 26) at 1, 2, 3, 5, and 7 days of age. All infants had moderate/severe encephalopathy; perinatal depression (10 minute Apgar &lt;5, pH &lt;7.00 or base deficit ≥15, or resuscitation at 10 minutes); and received hypothermia. Primary outcome was neurodevelopment at 12 months assessed by the Alberta Infant Motor Scale and Warner Initial Developmental Evaluation. Two independent observers rated MRI brain injury severity by using an established scoring system.

RESULTS:
The mean age at first study drug was 16.5 hours (SD, 5.9). Neonatal deaths did not significantly differ between Epo and placebo groups (8% vs 19%, P = .42). Brain MRI at mean 5.1 days (SD, 2.3) showed a lower global brain injury score in Epo-treated infants (median, 2 vs 11, P = .01). Moderate/severe brain injury (4% vs 44%, P = .002), subcortical (30% vs 68%, P = .02), and cerebellar injury (0% vs 20%, P = .05) were less frequent in the Epo than placebo group. At mean age 12.7 months (SD, 0.9), motor performance in Epo-treated (n = 21) versus placebo-treated (n = 20) infants were as follows: Alberta Infant Motor Scale (53.2 vs 42.8, P = .03); Warner Initial Developmental Evaluation (28.6 vs 23.8, P = .05).

CONCLUSIONS:
High doses of Epo given with hypothermia for hypoxic-ischemic encephalopathy may result in less MRI brain injury and improved 1-year motor function.
