Existen diversas clases de funciones que generan números primos, algunas ellas son capaces producir al enésimo número primo; como es el caso la fórmula Willans (1964) y Ruiz Sondow (2014). En presente trabajo se ofrece propuesta una función a(n) basada en 2 divisor d(n), cual genera primos. Para secuencia definida como: = n · 2/(n- d(n)) con > 1, demuestra produce solo ceros primos tal maner...

The physiopathological mechanism involves the interaction between T lymphocytes/NK cells and macrophages, at the origin of an uncontrolled activation of the macrophages. The consequence is a hemophagocytosis extending to numerous organs, preferentially bone marrow. Clinical sympt...

In this paper we consider by elementary methods the Robinson theory Q, subtheory of the firstorder Peano Arithmetic PA, and a model of Q given by a universe of polynomials, thati is non-isomorphic to the standard model of PA. Sommario Nel presente lavoro si considera elementarmente la teoria di Robinson Q, sottoteoria dell’Aritmetica di Peano del primo ordine PA, ed un modello di Q costituito d...

This paper aims to summarize the recent progress of researches on the primo vascular system (PVS) and to analyze characteristics between PVS and traditional Chinese meridians. With the distribution, position features, identification and origin of PVS, and its function related to meridians elaborated on, we propose that there is still a lack of enough evidence to support the correlation between ...

O artigo defende a hipótese de que talvez o impacto maior dos testemunhos livros Primo Levi venha seu tom sóbrio, preciso, quase neutro, típico uma descrição orientada pela racionalidade iluminista, Aufklärung, mas, ao mesmo tempo, desprovida do otimismo latente costumava acompanhar tal confiança na razão. Uma linguagem clara, sintaxe clássica, combinam sem problema com situações absurdas e cru...
