A qualitative understanding of the basic properties of complicated physical phenomena can often is obtained through the study of analytic solutions derived from simplified problems. Analytic solutions of shoreline change model for simple shoreline configurations are derived under idealized wave conditions. Both analytic and numerical methods are based on the one-line theory of shoreline change. In this paper some results of comparison of the numerical with analytic solutions are presented.

As a generalization of single value neutrosophic rough sets, the concept of multi-granulation neutrosophic rough sets was proposed by Bo et al., and some basic properties of the pessimistic (optimistic) multigranulation neutrosophic rough approximation operators were studied. However, they did not do a comprehensive study on the algebraic structure of the pessimistic (optimistic) multigranulation neutrosophic rough approximation operators. In the present paper, we will provide the lattice structure of the pessimistic multigranulation neutrosophic rough approximation operators. In particular, in the one-dimensional case, for special neutrosophic relations, the completely lattice isomorphic relationship between upper neutrosophic rough approximation operators and lower neutrosophic rough approximation operators is proved.

The simplest possible structural transition that an electronic system can undergo is Wigner crystallization. The aim of this short review is to discuss the main aspects of three recent experimets on the one dimensional Wigner molecule, starting from scratch. To achieve this task, the Luttinger liquid theory of weakly and strongly interacting fermions will be shortly addressed, together with the basic properties of carbon nanotubes that are require. Then, the most relevant properties of Wigner molecules will be addressed, and finally the experiments will be described.

O presente texto ocupa-se, portanto, da eucaristia enquanto ato instituinte do ser e busca pensar o referido rito a partir da perspectiva de Mikhail Bakhtin. Desta feita e a partir do enfoque da antropologia, se ancora em certas sínteses na medida em que, a validade daquilo que se pressupõe verdade, do ponto de vista da cognição, não depende do fato desta ser ou não ser conhecida por alguém. Pois, é o homem que une fé e rito, que une verdades da ciência e fenômenos físicos. Desta feita, tem-se então que, quando postulamos a existência de Deus a partir de certos escritos canônicos – e o reafirmamos no rito eucarístico – lhe conferimos existência e tangibilidade. Sobretudo, defende- se no decorrer do texto que a eucaristia, seja enquanto ato instituinte, seja enquanto rito, nada mais é do que uma enunciação de si sobre si que só tem significado, manifesto em seu conteúdo- sentido, se enunciado por aquele que experimenta e executa o ato.</p></div></div><div class="layoutArea"><div class="column"><p><span>P</span><span>ALAVRAS</span><span>-C</span><span>HAVE</span><span>: </span><span>Eucaristia.

This paper analyzes the Eucharist rite as instituted act of being and aims think that rite in the Mikhail Bakhtin ́s perspective. So, from an anthropology's approach, it is based in some perspectives that recognize validity in of what is assumed true, in a cognition point of view, depends on whether this is or is not known to anyone. That is because the man is the one who unites faith and rite, truths of science and physical phenomena. Therefore, when we postulate the existence of God from certain canonical writings - and reaffirm the Eucharistic rite, we give him existence and tangibility. Most of all, this text argued that the Eucharist is as instituted act or a rite, is nothing more than a statement of itself that only has meaning, manifest in their content-sense, if enunciated by one who experience and performs the act. </span></p><p><span>K</span><span>EYWORDS</span><span>: </span><span>Eucharist.

The contribution deals with the fractional heat conduction models and their use for determining thermal diffusivity. A brief historical overview of the authors who have dealt with the heat conduction equation is described in the introduction of the paper. The one-dimensional heat conduction models with using integer- and fractional-order derivatives are listed. Analytical and numerical methods of solution of the heat conduction models with using integer- and fractional-order derivatives are described. Individual methods have been implemented in MATLAB and the examples of simulations are listed. The proposal and experimental verification of the methods for determining thermal diffusivity using half-order derivative of temperature by time are listed at the conclusion of the paper.

In this paper, we consider the shallow water wave model in the (2+1)-dimensions. The Hirota simple method is applied to construct the new dynamics one-, two-, three-, [Formula: see text]-soliton solutions, complex multi-soliton, fusion, and breather solutions. By using the quadratic function, the one-lump, mixed kink-lump and periodic lump solutions to the model are obtained. The Hirota bilinear form variable of this model is derived at first via logarithmic variable transform. The physical phenomena to this model are explored. The obtained results verify the proposed model.
