It was realized the quantification of blood lead, benzene (phenol) and toluene (hipuric acid) metabolites in urine of 158 mechanic and lubricant center workers. Workers usually use fuel(gasoline, kerosene and diesel-2) and other solvents (thinner, aguarras, paints diluent, etc.) which have toxic components as lead, benzene and toluene. The blood lead quantification was perfoled with the Atornlc Absorption Spectrophotometry (AAS) method it showed that blood The data was analyzed using the statistical package SPSS versión 9,0. Conclusions: The older adult has more probability of being more susceptible to secondary effects or adverse reactions for the enalapril administration or of nifedipino.

This article presents the change from a non-determinist fnite automaton (AFN) into a determinist finite automaton (AFD), making use of a subset construction. The subset construction algorithm is based on the transitive closure or ? ?lock. Its implementation is done through a C++ language program, whose code and output are thoroughly presented.

This article presents a proposal for developing an Enterprise Information System's Architecture that could be useful in a Small and Micro-Enterprise (Pyme) Information Management, considering a case such of LICON S.A., a peruvian enterprise.

This article presents a program simulating the Cache Memory, by considering the system's success percentage and average access time.The program finds the Cache Memory's optimal size with regard to the RAM Memory size, which can be used as a valid criterion in designing both kinds of Memory within a computer.

This article presents the implementation of a data abstract type to represent the Set Theory Mathematical Concept, The program has been written in C++ Program Language applying the Object Oriented Programming Paradigm through a Dev C++ v.4.1 Compiler, a GNU compiler with GPL licence.

When calculations are performed on a computer is the problem of the accuracy or acuracidad of these. Paraanalizar this problem calculate the mean and standard desciación with a hypothetical set of test data are examined. The programming language C + + is used, using two different algorithms in the calculation; came forward, and others to conclude that acuracidad depends on the algorithm used and the ability to represent data from a computer.

This article presents a C++ Program implementing the Commutative or Abelian Group Algebraic Concept. The whole Program code that manages abelian class objects as a new data abstract type, TAD, using concepts such as operators overcharge is shown. Implementation has been carried out in a Dev C++ 4.1 compiler, a GNU compiler with GLP licence.

La contaminación se ha convertido en un problema visible y cotidiano. Las actividades industriales de distinto orden y las aguas servidas que se arrojan desde las ciudades sin ningún tratamiento, son las mayores fuentes de contaminación de los recursos hídricos. A esto se añade la convivencia con animales de pastoreo junto a las fuentes y a prácticas inadecuadas de uso, que provocan también contaminación a pequeña escala. Las actividades productivas de más fuerte impacto contaminante son la minera - petrolera, a industrial y la agroindustrial, por el excesivo uso de agrotóxicos

En este trabajo de investigación presentamos una breve introducción a los espacios riemannianos globalmente simétricos, siendo la conexión afín, denotada por r; un elemento importante para establecer definiciones, efectuar las pruebas de los teoremas y lemas más importantes que nos permiten identificar las características topologógicas de tales espacios. Iniciamos definiendo la simetría geodésica, como medio para definir los espacios localmente simétricos afines e introducir los espacios riemannianos globalmente simétricos por medio del grupo de isometrñias I(M) y del tensor curvatura R.

The article is an introduction to the study of the problem of the planning of the movement of a vehicle or robot. For it, first thinks about a solution to determine the difficulty of the terrestrial one and then to plan then movement lo continue inside him.

El objetivo del presente trabajo prospectivo-descriptivo-aplicativo es analizar la utilización de la técnica de Laminotomía Modificada en el tratamiento de 14 pacientes con lipoma extra intrarraquídeo hospitalizados consecutivamente desde enero 1993 a Julio de 1998 en la Unidad de Neurocirugía Pediátrica del Hospital Edgardo Rebagliati Martins - EsSalud. El seguimiento postoperatorio mediato fue de tres meses a cinco años. Dicha técnica facilitó I) la resección total de la lesión lipomatosa extra e intrarraquídea (epidural­subdural): 2) la liberación medular y radicular de la lesión que los comprometía y de sus anclajes: y 3) la permanencia de la estabilidad anatomofuncional de la columna. En el postoperatorio inmediato y mediato se encontró: 0% de deterioro neurológico: dehiscencia mínima de la herida operatoria, en tres pacientes, con mejoría notable en los ocho dí...

In this age of information, where people live around the internet; many business activities are carried unaINTRANET. The aim is to have the current state of a company operacines day after day. In the academic field; Today it is important to build institutional portals, so that the student or graduate ehresado, can count on the timely and effective information. the objective of acad emic {virtual project is to have an intranet at the Faculty of Industrial Engineering, to have timely information from diverdas operations performed in the university; especially in the academic aspect of the assessment and to have this information in cualquien time.
