Bifurcating Nodoids in Hyperbolic Space
Authors: Jleli Mohamed , López Rafael 
Published: March 2016

Abstract
Consider in hyperbolic space ℍ3 the one parameter family of immersed (non embedded) constant mean curvature surfaces of revolution Dπ with constant mean curvature H > 1. The parameter π ∈ (−∞, 0) is the analogue of the “necksize” of the Delaunay surfaces in Euclidean space. It is proved that when π → -∞, there exists a branch of surfaces with constant mean curvature H which bifurcate from Dπ. Furthermore, we prove that these new surfaces have only a discrete group of symmetries. The proof consists in a detailed study of the behaviour of the eigenvalues of the Jacobi operator when π tends to − ∞, together the bifurcation theorem of Crandall-Rabinowitz.

Authors: Marcos do Ó João , Macedo Abiel Costa 
Published: March 2016

Abstract
In this paper we give a new Adams type inequality for the Sobolev space Wm,2(ℝ2m). By using this inequality in combination with mini-max method we establish the existence of nontrivial solutions to the following class of polyharmonic equations
(−Δ)mu(x) + u(x) = f (|x|, u), in ℝ2m,
where the nonlinearity is “superlinear” and has critical exponential growth at infinite.
A Priori Bounds and Existence of Solutions for Slightly Superlinear Elliptic Problems
Authors: García-Melián J. , Iturriaga L. , Quoirin H. Ramos 
Published: March 2016

Abstract
We consider the semilinear elliptic problem

where a is a continuous function which may change sign and f is superlinear but does not satisfy the standard Ambrosetti-Rabinowitz condition. We show that if f is regularly varying of index one at infinity then the above problem has a positive solution, provided α satisfies some additional assumptions. Our proof uses an abstract theorem due to L. Jeanjean on critical points of functionals with mountain-pass structure, and it relies on the obtention of a priori bounds for positive solutions..
Two-Level Spline Approximations for Two-Dimensional Navier–Stokes Equations
Authors: Shao Xinping , Han Danfu , Hu Xianliang 
Published: March 2016

AbstractTheC1$C^{1}$spline spaces with degreed≥5$d\geq 5$over given triangulations are implemented in the framework of multi-variate spline theory. Based on this approach, two-level methods are proposed by using various order spline spaces for the steady state Navier–Stokes equations in the stream function formulation. The proposed method can be reduced to solving a linear equation in the high-order spline space and the nonlinear equations in the low-order spline space. The convergence analysis is given based on the Newton iteration. Besides, the matrix forms of the two-level scheme are also presented. We finally tabulate the numerical results to validate and show the efficiency of the proposed two-level spline methods.
Application of a multisurface discrete crack model for clear wood taking into account the inherent microstructural characteristics of wood cells
Authors: Lukacevic Markus , Füssl Josef 
Published: March 2016

Abstract
A more accurate prediction of the mechanical behavior of wood is needed to increase its ability to compete with other building materials. Especially, when it comes to estimate failure loads, the lack of appropriate prediction tools becomes obvious. The present work contributes to this goal in two different ways: First, a damage concept for wood is revisited, which allows for transferring information about failure processes through different scales of observation. In this concept, the failure behavior of clear wood is linked to the different characteristic of earlywood and latewood layers in softwoods. This reduces the number of empirically determined strength parameters, while the definition of multisurface failure criteria is still possible. Secondly, it will be demonstrated that the combination of these models with discrete crack modeling based on the extended finite element method provides a numerical simulation tool capable to describe failure mechanisms more realistically than existing approaches. The results obtained by numerical calculations and experiments by means of a micro wedge splitting test show very good agreement, especially, if the load capacity and failure mechanisms are in focus. The presented approach shows a much better performance compared to linear elastic or elastoplastic simulations.

Abstract
A large amount of monolignol glucosides (MLGs: p-glucocoumaryl alcohol, coniferin, syringin) are found in lignifying soft xylem near cambium and they disappear with the progress of lignification. Recently, it became a matter of debate whether those MLGs are real intermediates in lignin biosynthesis or only a storage form of monolignols outside of the main biosynthetic pathway. The latter is partly based on a misinterpretation of 14C-tracer experiments and partly on the simple generalization of the results of gene manipulation experiments concerning the flexible and complex lignification. In the present paper, it could be confirmed by the most reliable 13C-tracer method that MLGs are real intermediates in the pathway from l-phenylalanine to macromolecular lignin-polysaccharides complexes in the cell walls. This pathway via MLGs is essential for transport and programmed delivery of specific monolignols in a stable form from intracellular space to specific lignifying sites within the cell wall. The pool size of MLGs is large in most gymnosperm trees and some angiosperm species that emerged in an early stage of phylogeny, while the pool size is small in most angiosperms. This difference in pool size is reasonably understandable from the viewpoint of plant evolution, in the course of which the role of MLGs changed to meet variation in type of major cells, reaction wood formation, and postmortem lignification.
Experimental and Kinetic Study of Esterification of Acrylic Acid with Ethanol Using Homogeneous Catalyst
Authors: Jyoti Ghoshna , Keshav Amit , Anandkumar J. 
Published: March 2016

Abstract
Esterification of acrylic acid with ethanol, catalyzed by sulfuric acid has been carried out in stirred batch reactor under atmospheric pressure. Different parameters such as effect of initial molar ratios of the reactants, effect of catalyst concentration, initial water and effect of temperature has been studied in the batch reactor. Different catalyst loading system (1–3 vol%), reaction temperatures (50–70 °C), initial reactants molar ratio (1:1–1:3) and water concentration in feed (0–20 vol%) was used in the reaction system. The temperature dependence is exponential and expressed by Arrhenius type of relationship. Kinetics parameters such as equilibrium constant, rate constants, activation energy and reaction enthalpy and entropy were estimated by experimental data. The rate equation has a remarkable fit to the data and was able to describe the behavior of the system at various reaction temperatures. Hydrochloric acid (HCl) and hydro iodic acid (HI) were also compared with sulphuric acid as catalyst for esterification of acrylic acid with ethanol. Sulphuric acid was found to be more efficient catalyst for esterification as it induces the maximum conversion of acrylic acid.
Preparing Allicin Nanocapsules and Determining the Factors Controlling Their Particle Size through Artificial Intelligence

Published: March 2016

Abstract
Allicin nanocapsules were prepared via ionotropic pre-gelation. The wall materials were alginate-chitosan biopolymers. Nanocapsules were characterized using Fourier transform infrared spectroscopy (FT-IR) and field emission scanning electron microscopy (FE-SEM). We tried to simulate the effects of three different variables on particle size through artificial intelligence approaches. Feedforward neural networks (FFNN) and adaptive neuro-fuzzy inference system (ANFIS) were employed to model the size of allicin nanocapsules, and the latter was found to be relatively more successful in this regard. Finally, genetic algorithms were employed to determine the optimal values for the variables at which the smallest particles were formed.
Matching as a Stochastic Process
Authors: Bolle Friedel , Otto Philipp E. 
Published: March 2016

Abstract
Results of multi-party bargaining are usually described by concepts from cooperative game theory, in particular by the core. In one-on-one matching, core allocations are stable in the sense that no pair of unmatched or otherwise matched players can improve their incomes by forming a match. Because of incomplete information and bounded rationality, it is difficult to adopt a core allocation immediately. Theoretical investigations cope with the problem of whether core allocations can be adopted in a stochastic process with repeated re-matching. In this paper, we investigate sequences of matching with data from an experimental 2×2 labor market with wage negotiations. This market has seven possible matching structures (states) and is additionally characterized by the negotiated wages and profits. First, we describe the stochastic process of transitions from one state to another including the average transition times. Second, we identify different influences on the process parameters as, for example, the difference of incomes in a match. Third, allocations in the core should be completely durable or at least more durable than comparable out-of-core allocations, but they are not. Final bargaining results (induced by a time limit) appear as snapshots of a stochastic process without absorbing states and with only weak systematic influences.
New Chinglish and the Post-Multilingualism challenge: Translanguaging ELF in China
Authors: Wei Li 
Published: March 2016

Abstract
Building on the extensive ELF research that aims to reconceptualise English as a resource that can be appropriated and exploited without allegiance to its historically native speakers, this article explores the issue of English in China by examining New Chinglish that has been created and shared by a new generation of Chinese speakers of English in China and spread through the new media. This new form of English has distinctive Chinese characteristics and serves a variety of communicative, social and political purposes in response to the Post-Multilingualism challenges in China and beyond. I approach New Chinglish from a Translanguaging perspective, a theoretical perspective that is intended to raise fundamental questions about the validity of conventional views of language and communication and to contribute to the understanding of the Post-Multilingualism challenges that we face in the twenty-first century.
ELF in the making? simplification and hybridity in abstract writing
Authors: Lorés-Sanz Rosa 
Published: March 2016

AbstractThe fact that in the last few decades English has become the international language of scientific communication has brought with it an increasing pressure on non-Anglophone academics to disseminate their research internationally in English. Some disciplinary areas, such as Sociology, which have traditionally been dominated by Anglophone writers, are witness to an increasing number of non-native academics publishing in their most prestigious journals, hosted either in the United States or in Great Britain. This may have implications for the way academic texts are being written. This paper focuses on the evolution of the prestigious journalSocial Science Researchsince it was launched in 1972. My research hypothesis is that the fact that an increasing number of non-Anglophone writers are contributing to the journal may be modifying the rhetorical level of the research article abstracts. The analysis carried out in this study identifies processes of evolution in terms of simplification of the conventional rhetorical structure used for abstracts, and hybridization, which in fact involves a higher degree of textual complexity. The new, hybrid, patterns identified here may be the result of processes of contact and evolution, reshaping old forms into new forms that model English conventional patterns in innovative and creative ways. Further enquiry is needed to test the preliminary results yielded by the present study.

Palladium catalyzed oxidative aminations and oxylations: where are we?
Authors: Lorion Mélanie M. , Oble Julie , Poli Giovanni 
Published: March 2016

Abstract
Selective product formation in the Pd-catalyzed cyclization of unsaturated amide and carboxylic acid derivatives is an intriguing and challenging task. We recently discovered that the oxidative intramolecular Pd(II)-catalyzed amination or oxylation of unsaturated N-sulfonyl carbamates, N-sulfonyl carboxamides and carboxylic acids takes place through the involvement of cyclic (usually, 5- or 6-membered) aminopalladated (AmPIs) or oxypalladated (OxPI) intermediates. Such cyclic intermediates can undergo a variety of transformations such as distocyclic β-H elimination, oxidative acetoxylation or intramolecular carbopalladation, depending upon the substrate and/or the reaction conditions. In the absence of appropriate reaction pathways, the cyclic nucleopalladated intermediates (NuPIs) simply engage in an inconsequential equilibrium with the initial substrate and other transformations occur such as allylic C–H activation or, in the particular case of allyl carbamates, [3,3]-sigmatropic rearrangement.
Impact of Velocity Slip and Temperature Jump of Nanofluid in the Flow over a Stretching Sheet with Variable Thickness
Authors: Guo Chengjie , Zheng Liancun , Zhang Chaoli , Chen Xuehui , Zhang Xinxin 
Published: March 2016

Abstract
In this study, the generalised velocity slip and the generalised temperature jump of nanofluid in the flow over a stretching sheet with variable thickness are investigated. Because of the non-adherence of the fluid to a solid boundary, the velocity slip and the temperature jump between fluid and moving sheet may happen in industrial process, so taking velocity slip and temperature jump into account is indispensable. It is worth mentioning that the analysis of the velocity v, which has not been seen in the previous references related to the variable thickness sheet, is presented. The thermophoresis and the Brownian motion, which are the two very important physical parameters, are fully studied. The governing equations are simplified into ordinary differential equations by the proper transformations. The homotopy analysis method (HAM) is applied to solve the reduced equations for general conditions. In addition, the effects of involved parameters such as velocity slip parameter, temperature jump parameter, Prandtl number, magnetic field parameter, permeable parameter, Lewis number, thermophoresis parameter, and Brownian motion parameter are investigated and analysed graphically.

<p>Jambi region was constituted by plural society. The social relations formed within a long period had created a conducive environment for plural society. The citizens were used to deal with people from different social and cultural background, and the differences of social class, religion, group and culture did not trigger conflict. Furthermore, interactions among ethnics, i. e. Melayu, Jambi, Minangkabau, Banjar, Bugis, Java and Batak even gave birth to new identity; the Jambi society. Nonetheless, the infiltration of big capital owners and trans-migration in 1990s had shaken this stability. The climax took place during the reformasi when a huge number of unrests surfaced, where society demanded the return of the land to the hands of people. It was important to build and employ attempts to lessen the tense and conflicts in this plural society. The local wisdom of Jambi people which has been formed for decades needed to be returned as a foundation for this attempt. Before capitalism dominated the life of the society, the values of local wisdom were proven to keep the plural society in harmony.</p><p> </p><p>Wilayah Jambi dihuni oleh masyarakat yang plural.

<p>After Indonesia declared its independence, the management of the private companies became a big problem for a new government, Indonesia. Expropriation efforts for those western private plantation companies actually had been developed in the first year of the independence and it continued until the Dutch-Indonesian Round Table Conference. There were three processes passed through companies’ transformation of the western private plantation in Indonesia, namely decolonization, Indonesia-nization and nationalization. Nationalization was legally based on the Indonesian Ordinance number 86 1958, but the real process occured since a year ago. Therefore, Indonesia had to give financial compensation to the owner, but the reality was that this aspect was still unfinished until the end of Sukarno regime.
