About the transitivity of the property of being Segal topological algebra

We show that if (A, f, B) and (B, g, C) are left (right or two-sided) Segal topological algebras for which g(f(A))⊆ g(B)g(f(A))  (g(f(A))⊆ g(f(A))g(B)  or  g(f(A))⊆ g(B)g(f(A))∩ g(f(A))g(B), respectively), then (A, g∘ f, C) is also a left (right or two-sided, respectively) Segal topological algebra

About the joint spectrum of vector-valued functions

We generalize the results of Abtahi and Farhangi about the joint spectrum and A-valued spectrum of a vector-valued map from the class of unital commutative semisimple Banach algebras to the case of unital topological algebras

Coincidence of topological Jacobson radicals in topological algebras

Several classes of topological algebras for which the left topological Jacobson radical coincides with the right topological Jacobson radical are described

Ford Lemma for topological ∗-algebras

Abstract. Several analogies of Ford lemma for topological algebras (in particular, for topological *-algebras) are proved (without using projective limits). Topological *-algebras, in which a self-adjoint element a with sp A (a) ⊂ (0, ∞) has a self-adjoint square root b with sp A (a) ⊂ (0, ∞) and sp Key words: advertive algebras, Ford lemma, Gelfand-Mazur algebras, locally pseudoconvex algebras, simplicial algebras, square root of an element, topological *-algebras. At several places in the development of the theory of topological *-algebras (especially, of the theory of Banach *-algebras and locally m-convex *-algebras) a self-adjoint square root for a self-adjoint element with a positive spectrum is needed.

The center of topologically primitive exponentially galbed algebras

Let A be a unital sequentially complete topologically primitive exponentially galbed Hausdorff algebra over ℂ, in which all elements are bounded. It is shown that the center of A is topologically isomorphic to ℂ

Exosomes in head and neck cancer. Updating and revisiting

Exosomes have gone from being considered simple containers of intracellular waste substances to be considered important carriers of cellular signals. Its broad capacity to promote tumour growth, both in situ and metastatic, has greatly intensified scientific research on them. In the same way and depending on its content, its tumour suppressive properties have opened a window of light and hope in the fight against cancer. In the present review we try to gather in a simple and understandable way the most relevant knowledge to date on the role of exosomes in oral squamous cell carcinoma, helping to understand their process of formation, release and activity on the tumour microenvironment

A Lambda Term Representation Inspired by Linear Ordered Logic

We introduce a new nameless representation of lambda terms inspired by ordered logic. At a lambda abstraction, number and relative position of all occurrences of the bound variable are stored, and application carries the additional information where to cut the variable context into function and argument part. This way, complete information about free variable occurrence is available at each subterm without requiring a traversal, and environments can be kept exact such that they only assign values to variables that actually occur in the associated term. Our approach avoids space leaks in interpreters that build function closures. In this article, we prove correctness of the new representation and present an experimental evaluation of its performance in a proof checker for the Edinburgh Logical Framework. Keywords: representation of binders, explicit substitutions, ordered contexts, space leaks, Logical Framework.Comment: In Proceedings LFMTP 2011, arXiv:1110.668

Propuesta de un sistema de gesti?n de recursos humanos para la industria cementera : el caso de Cementos Pacasmayo S.A.A.

La gerencia de recursos humanos de Cementos Pacasmayo busca que sus procesos est?n alineados con los objetivos, pol?ticas y estrategias de la empresa, siendo importante para ello el recurso humano. Sobre la base de los principales procesos de recursos humanos de la empresa, sumado los aspectos relevante tomados de los diferentes modelos de recursos humanos propuestos por autores, especialistas en la materia y, con informaci?n obtenida a trav?s de encuestas al personal y entrevistas a expertos se formula la siguiente propuesta de un sistema de gesti?n de recursos humanos, que considera: procesos integrados, interrelacionados y estandarizados; contingencias internas y externas; resultados organizacionales; la evaluaci?n organizacional a trav?s de auditor?as, y el an?lisis costo/beneficio de las actividades. Los procesos propuestos consideran los siguientes elementos: implementaci?n del proceso de planificaci?n; reclutamiento y selecci?n; an?lisis y dise?o de puestos; capacitaci?n; planeaci?n de carrera; remuneraciones; relaciones laborales; y bienestar del personal. Los resultados de esta propuesta tendr?n efectos tanto en la organizaci?n como en los recursos humanos propiamente dicho. Es importante considerar el aporte significativo del elemento de evaluaci?n de la gesti?n de recursos humanos, como un factor que brindar? informaci?n relevante para la organizaci?n en la toma de sus decisiones

Plan de negocio para determinar la viabilidad de constituir una empresa de dise?o y fabricaci?n de m?quinas trituradoras de Cizalla

Nuestra tesis, enfocada en la fabricaci?n de maquinaria industrial, aspira a ser una buena opci?n manufacturera que brinde: valor agregado a la materia prima, genere empleo y sobretodo que beneficie a la sociedad y al medio ambiente. Para ello, hemos identificado un problema de com?n denominador a nivel mundial, la excesiva generaci?n de residuos s?lidos, en contraparte hemos revisado soluciones para corregir y/o aliviar esta situaci?n, eligiendo la m?quina trituradora de cizalla como la opci?n m?s amigable y confiable para reducir el tama?o de los residuos s?lidos, cualquiera sea su origen. Para el Estudio de Mercado, ten?amos que estudiar el proceso de gesti?n de residuos s?lidos en Lima Metropolitana; y elegir certeramente nuestra posible cartera de clientes, en algunos casos ideando estrategias para crear la demanda la cual era nula. Estimada la demanda, ideamos el Plan de Marketing que haga atractivo y sostenible nuestro Plan de Negocio y en funci?n a ello creamos nuestro Plan de Operaciones, considerando proveedores, procesos, costos y legislaci?n vigente. Finalmente nuestro Plan Financiero reflej? que nuestra idea de negocio s? era rentable y atractiva. Esperamos que esta Tesis sea de gu?a para futuras ideas de negocios en nuestra incipiente industria manufacturera peruana
