Published: February 2017

BACKGROUNDZika virus (ZIKV) has spread in the Americas, including parts of the southern United States, and infection can be associated with serious complications, including congenital brain abnormalities. Probable transfusion transmission of ZIKV has been documented in Brazil.STUDY DESIGN AND METHODSPreemptive testing of blood donations for ZIKV RNA was implemented in southern US states at risk of local transmission using a test approved under a Food and Drug Administration (FDA) investigational new drug application, cobas Zika. Screening was expanded after issuance of an updated FDA guidance. Donations reactive on initial screening were further tested by nucleic acid and antibody tests to determine the donor status.RESULTSOf 358,786 donations from US states screened by individual donation testing, 23 were initially reactive on cobas Zika. Fourteen of these represented probable ZIKV infection based on reactivity on additional nucleic acid testing or anti‐Zika immunoglobulin M. Ten of the 14 donors reported travel to an identified ZIKV‐active area within 90 days before donation (median time from end of travel to donation, 25 days; range, 6‐71 days). Three donors with travel history also had a potential sexual exposure. Only seven of the 14 donations with probable ZIKV infection were detectable upon 1:6 dilution to simulate minipool testing. The estimated specificity of the cobas Zika test was 99.997%.CONCLUSIONScreening of donations for ZIKV RNA can interdict ZIKV‐infected donors. Donor risk factors include travel more than 4 weeks before donation and sexual exposure. Minipool screening would have detected only 50% of the RNA‐positive donations.
Spontaneous Interfacial Tension Changes at the Interface of Metal Chloride Nitrobenzene Solution and Aqueous Stearyltrimethylammonium Chloride Solution: the Role of Metal Ions
Authors: Arai Yuka , Tsuruki Yuta , Isobe Toshihiro , Nakajima Akira , Matsushita Sachiko 
Published: February 2017

Abstract
The authors examine the roles of chemical compounds that can generate spontaneous interface motion, especially in the Nakache and Dupeyrat system, which normally uses a stearyltrimethylammonium chloride (STA-Cl) aqueous solution and a KI + I2 nitrobenzene solution. The authors observed spontaneous behavior at the interface of a system comprising the STA-Cl aqueous solution and a nitrobenzene solution of ZnCl2 or FeCl3. To investigate the role of metal ions, in-situ electrochemical measurements of systems of various metal halides, such as KCl, CaCl2, AlCl3, ZnCl2, and FeCl3, were conducted and discussed regarding the relationship of the spontaneous interface motion with the consideration of standard Gibbs energy of surfactant adsorption, solubility into the oil phase, and hydration enthalpy. The importance of electric potential dependence of surfactant adsorption–desorption at the oil/water interface is suggested and supported using an FeCl3 chlorobenzene solution. A material design with the consideration of a potential barrier of surfactant desorption would enable us to obtain a spontaneous motion system not utilizing toxic substances.

Published: February 2017

Abstract
An introduction of two arylborane charge transfer (CT) units to the periphery of 1,10-phenanthroline (B2phen) or 2,2′-bipyridine (B2bpy) in a tricarbonyl rhenium(I) diimine complex (fac-[Re(CO)3(B2phen)Br] = ReB2phen or fac-[Re(CO)3(B2bpy)Br] = ReB2bpy) resulted in unique redox, spectroscopic, and photophysical properties of the complex. In particular, the presence of the two arylborane units in the complex can enhance its metal-to-ligand CT absorption intensity in the visible region and the radiative rate constant, compared to those of the complexes without and with the single arylborane unit in the ligand. The single X-ray crystal structure of ReB2phen is also reported.
The Ferrements of poetry: The geopolitical vision of Aimé Césaire’s Cold War poems
Authors: Bonner Christopher T 
Published: February 2017

Abstract
This article examines the poems collected in Ferrements (1960) – the last collection of poems that Aimé Césaire would publish for another two decades – against the Cold War context of Césaire’s 1956 separation from Soviet communism. Critics tend to view this collection as either a reflection of Césaire’s disillusionment with radical politics or a turn away from avant-garde poetry. This article makes the case that the poems of Ferrements are in fact crucial to the development of Césaire’s political thought in this period of ideological rupture. As this article demonstrates, Césaire uses the conceptual tools of poetry towards a systematic analysis of the changed geopolitical situation of the global Cold War. The article focuses especially on Césaire’s extensive use of geographic imagery, his elegies for insurrectionary figures, and congruities between the poetics of Ferrements and the geopolitical stance of non-alignment.
Legends, memories and violence in North African cities: Urban space in Kateb Yacine’s Nedjma and Salim Bachi’s Le chien d’Ulysse
Authors: Panizzon Philippe 
Published: February 2017

Abstract
This article examines the role of urban space in two novels: Nedjma by Kateb Yacine and Le chien d’Ulysse by Salim Bachi. Drawing on Frantz Fanon’s observations about the colonial city in Les damnés de la terre and Michel de Certeau’s ideas on subversive practices of city dwellers in his L’invention du quotidien, this article explores the protagonists’ experiences in the colonial or postcolonial city and the way they remap the cities with their personal narratives. It demonstrates that in the face of urban transformation brought about by colonial or postcolonial violence the mythical dimension of the city – its legends, memories and myths harking back to a supposedly pristine Algerian past – is irretrievable. With particular reference to Jan Assmann’s theory of cultural memory and Max Silverman’s idea of palimpsestic memory, this article argues that violent nature of the cities’ past and present, along with their vanished cultural memory, prohibits the protagonists from creating a coherent historical narrative around the city, and in a wider sense from developing and sustaining the future character of Algerian cultural and national identity.

AbstractThe rare coumarins stenocarpin, stenocarpin isobutyrate, oficinalin, oficinalin isobutyrate, 8-methoxypeucedanin and the known xanthotoxin, isoimperatorin, bergapten, peucedanin and 8–methoxyisoimperatorin were isolated fromPeucedanum luxuriansTamamsch. (Apiaceae) and identified by means of spectral data (1D and 2D NMR). Their immunomodulating activity was evaluated by flow cytometry and their influence on HL60 cells as well as on PHA-stimulated PBLs was tested. All tested coumarins induce apoptosis (maximal in the 48 h culture) and decrease cell proliferation in a time- and dose-dependent manner, especially in HL60 cells. They also induce partial G1 block, but only in HL60 cells (at 100 µM concentrations). Dose-dependent reduction of RNA content was also found in G1 cells treated by the coumarins. All of the tested coumarins also possessed immunomodulatory activities. Bergapten and xanthotoxin were found to be the best candidates for further evaluation as anti-cancer drugs.

Enhancement of Gel Properties of Sardine Surimi using Squid Ink Tyrosinase in Combination with Coconut Husk Extract
Authors: Vate Naveen Kumar , Benjakul Soottawat 
Published: February 2017

Abstract
Squid ink tyrosinase (SIT) at levels of 300 and 500 KU kg−1 protein in combination with ethanolic extract of coconut husk (EEC) at concentrations of 1 and 1.25 g kg−1 protein was added into sardine surimi and the resulting gels were examined. The use of SIT (500 KU kg−1 protein) and EEC (1.25 g kg−1 protein) yielded the gel with the highest breaking force and deformation (p < 0.05). Nevertheless, the expressible moisture content and whiteness scores were markedly decreased. Protein cross-linking of surimi gels increased as evidenced by the decreased band intensity of myosin heavy chain (MHC). This coincided with the increased storage modulus (G'). Based on microstructure study, finer and more compact structure of surimi gels added with both SIT and EEC were obtained, compared to the control. Thus, SIT in conjunction with EEC could be used as the novel surimi gel strengthener.

Published: February 2017

Abstract
In this paper, we study the dynamics of a reaction-diffusion Cellular Nonlinear Network (RD-CNN) nodel in which the reaction term is represented by Brusselator cell. We investigate the RD-CNN dynamics by means of describing function method. Comparison with classical results for Brusselator equation is provided. Then we introduce a new RD-CNN model with memristor coupling, for which the edge of chaos regime in the parameter space is determined. Numerical simulations are presented for obtaining dynamic patterns in the RD-CNN model with memristor coupling.
The algebraic size of the family of injective operators
Authors: Bernal-González Luis 
Published: February 2017

Abstract
In this paper, a criterion for the existence of large linear algebras consisting, except for zero, of one-to-one operators on an infinite dimensional Banach space is provided. As a consequence, it is shown that every separable infinite dimensional Banach space supports a commutative infinitely generated free linear algebra of operators all of whose nonzero members are one-to-one. In certain cases, the assertion holds for nonseparable Banach spaces.

Nonlinear Responses and Stability of an Elastic Suspended Cable System Subjected to Parametrical External Excitations
Authors: Dai Liming , Xia Dandan , Chen Changping 
Published: February 2017

AbstractThis research investigates the nonlinear behavior and stability of an elastic suspended cable system under combined parametric and external excitations, with an approach of higher accuracy and reliability. Geometric nonlinearity of the cable and its in-plane and out-of-plane vibrations are considered. Multiple solutions of the system are found existing, corresponding to a single frequency of external excitation. The nonlinear stability of the cable system is investigated with focus on the influence of different system parameters. With the newly developed Periodicity-Ratio (P-R) method, the influences of different external excitations on the nonlinear vibrations of the cable system are examined, and a periodic-nonperiodic-chaotic region diagram is created for quantitatively and graphically identifying the stability and nonlinear behavior of the system.

Authors: Gómez Francisco , Escalante Enrique , Calderón Celia , Morales Luis , González Mario , Laguna Rodrigo 
Published: February 2017

Abstract
This paper presents the alternative construction of the diffusion-advection equation in the range (1; 2). The fractional derivative of the Liouville-Caputo type is applied. Analytical solutions are obtained in terms of Mittag-Leffler functions. In the range (1; 2) the concentration exhibits the superdiffusion phenomena and when the order of the derivative is equal to 2 ballistic diffusion can be observed, these behaviors occur in many physical systems such as semiconductors, quantum optics, or turbulent diffusion. This mathematical representation can be applied in the description of anomalous complex processes.

Authors: Amudhavalli A. , Manikandan M. , Jemmy Cinthia A. , Rajeswarapalanichamy R. , Iyakutti K. 
Published: February 2017

Abstract
The structural stabilities of cobalt mononitride (CoN) and nickel mono-nitride (NiN) were investigated among the crystal structures, namely, NaCl (B1), CsCl (B2), and zinc blende (B3). It was found that the zinc blende (B3) phase was the most stable phase for both nitrides. A pressure-induced structural phase transition from B3 to B1 phase was predicted in these nitrides. The computed lattice parameter values were in agreement with the experimental values and other theoretical values. The electronic structures reveal that these nitrides are metallic at zero pressure. The computed elastic constants indicate that CoN and NiN are mechanically stable in the B1 and B3 phases. The variations of the elastic constants, bulk modulus, shear modulus, Poisson’s ratio, and elastic anisotropy factor with pressure were investigated. The Debye temperature θ
D values are reported for both the nitrides in their B1 and B3 phases. The high-pressure NaCl phase of both CoN and NiN were found to be ferromagnetic.
Bonding Situation of Bis-gold Chloride Complexes with N-heterocyclic Carbene-Analogues [(AuCl)2-NHEMe] (E=C – Pb) based on DFT Calculations

Published: February 2017

Abstract
We computationally investigated the structure and bonding situation of bis-gold chloride complexes, (AuCl)2, containing N-heterocyclic carbenes and analogues, called tetrylenes [(AuCl)2-NHEMe] (Au2-NHE) with E=C to Pb, using density functional theory (DFT) at the BP86 level with the basis sets def2-SVP, def2-TZVPP, and TZ2P+. The nature of the (AuCl)2-NHEMe bond in the Au2-NHE complexes was analyzed using charge and energy decomposition methods. The calculated equilibrium structures of the Au2-NHE complexes showed that the tetrylene ligands, NHEMe (E=C to Ge), are bonded in a head-on fashion to the bis-gold chloride fragment, (AuCl)2, and that the structure of Au2-NHSn contains a distorted head-on NHSn ligand, and the NHPb ligand is bonded in a side-on mode to the bis-gold chloride fragment, (AuCl)2. The theoretical calculation of bond dissociation energy (BDE) suggests that the bis-gold chloride-NHEMe bond strength increases from Au2-NHC to Au2-NHSi and then significantly decreases from Au2-NHSi to Au2-NHSn, and the strongest bond is exhibited for Au2-NHPb. The EDA-NOCV results and NOCV pairs indicate that the NHEMe ligand in the Au2-NHE complexes is a strong σ-donor and a weak π-acceptor, as well as a very weak π-donor (AuCl)2←{NHEMe}. The trend in the Au-E bond strength resulted from the increase in (AuCl)2←NHEMe donation. The results of this study may establish an interesting class of compounds worthy of further study.
Synthesis of N-doped Carbon Xerogel (N-CX) and its Applications for Adsorption Removal of Microcystin-LR
Authors: Wu Laiyan , Lan Jirong , Wang Songbo , Zhu Junjiang 
Published: February 2017

Abstract
N-doped carbon xerogel (N-CX) is synthesized and used for adsorption removal of microcystin-LR (MC-LR) from aqueous solution. Characterizations including N2 physisorption, TEM and XPS indicate that N atoms are doped into the N-CX and the material has porous structure. Adsorption tests show that the N-CX is efficient for MC-LR adsorption, with adsorption capacity of 1916.2 μg g−1, which is higher than that of commercial activated carbon (1034.13 μg g−1) and graphene oxide (1700 μg g−1). The material is recyclable after desorption treatment by washing with NaOH solution, with no loss of uptake within five cycles. Effect of initial MC-LR concentration, temperature, and pH on the adsorption behavior is further investigated, to realize the adsorption process, showing that the adsorption process obeys the Langmuir isotherm and pseudo-second-order equation. Thermodynamical calculation indicates that the adsorption of MC-LR onto N-CX is a spontaneous and exothermic process, with the Gibbs free energy (ΔG) of −16.1 kJ mol−1 and enthalpy (ΔH) of −18.45 kJ mol−1.
Pilot‐Scale Evaluation of pH‐Based Control of Single Stage Deammonification Processes for Sidestream Treatment
Authors: Graham David M. , Jolis Domènec 
Published: February 2017

ABSTRACT: Pilot scale sidestream reactors, utilizing a pH‐based control strategy, were operated at the San Francisco Public Utilities Commission (SFPUC), Southeast Plant (SEP) for the biological treatment of anaerobically digested sludge centrate using combined partial nitritation/anaerobic ammonium oxidation (anammox) as the main nitrogen removal pathway. Reactors were setup to functionally simulate two full‐scale commercial processes common to the industry using nonproprietary, flexible, pH‐based process control strategy. Results demonstrated that comparable full‐scale loading rates and removal efficiencies can be reached for different reactor configurations while maintaining stable process performance using this relatively simple control strategy.
El concepto de conducta en psicología: un análisis socio-histórico-cultural
Authors: Polanco Fernando 
Published: February 2017

<p>El concepto de conducta o comportamiento, es de uso común en nuestro lenguaje. Sin embargo, durante el siglo XX alcanzó una relevancia inusitada convirtiéndose en el objeto de estudio de las ciencias sociales, particularmente de la psicología. Por ello, se realizó una revisión sociológica, histórica y cultural del concepto de conducta, bajo una metodología de estudio ex post facto, a través del análisis y descripción del mismo en fuentes primarias y secundarias. Como resultado se observó que dicho concepto tuvo dos usos: a) como sinónimo de carácter, con un significado moral y ético; b) un uso neutro y verbal, refiriéndose a todo lo que hace un organismo o cosa. Este último uso, fue el que tuvo mayor impacto en el campo de la psicología adquiriendo el lugar de objeto de estudio. Sus alcances y dimensiones fueron amplios, teniendo un núcleo central de ideas compartidas por todos, y una serie de hipótesis aledañas que se diferencian en aspectos variables. Es así que se concluye, que es importante definir de manera necesaria y objetiva dicho concepto, para no genera usos y alcances contradictorios o erróneos en el campo científico, sobre todo si el mismo forma parte de las categorías u objetos de estudio principal de la investigación, como en el caso de la psicología conductual.</p>
