In this new edition of their classic work on Cellular Solids, the authors have brought the book completely up to date, including new work on processing of metallic and ceramic foams and on the mechanical, electrical and ...

Se estudian políticas macroeconómicas de segundo mejor en economías abiertas donde puede haber problemas de sostenibilidad intertemporal y algunos grupos enfrentan potencialmente restricciones de acceso al crédito. S...

A general inductive approach for analysis of qualitative evaluation data is described. The purposes for using an inductive approach are to (a) condense raw textual data into a brief, summary format; (b) establish clear l...

Augmented marked graphs possess a special structure for modelling common resources as well as some desirable properties pertaining to liveness, boundedness, reversibility and conservativeness. This paper investigates the...

Los hongos son fuente de alimento y medicina desde tiempos remotos. Por su valor nutracéutico y como fuente de nutricéuticos se han utilizado para mantener y mejorar la salud, preservar la juventud y promover la longev...

Fil: Medina, Edén. Indiana University. School of Informatics; Estados Unidos. Este artículo presenta una historia de 'Proyecto Cybersyn', una computadora temprana desarrollada en Chile durante la presidencia socialista...

En "Estructura y dinámica del dominio de Santo Toribio de Liébana (siglos XIII-XVI)" se trata de explicar las características diferenciales que presenta un dominio monástico del área septentrional de la Península I...

Exopolysaccharides (EPS) are high molecular weight biopolymers produced by a wide range of microorganisms, including lactic acid bacteria (LAB). These polymers can be secreted to the external environment (slime EPS) or a...

Traditional workflow models have obvious shortcomings in describing complex workflows. Such complexity is due not only to the hierarchical property of business process, but also to the complicated dependencies among task...

"Temporal property graph databases track the evolution over time of nodes, properties, and edges in graphs. Computing temporal paths in these graphs is hard. In this paper we focus on indexing Continuous Paths, defined a...

"Açaí es la berry de una palmera monoica multicaule de la Amazonia, de más de 30 metros de altura, y con sus concentraciones más significativas en los pantanos del estado de Pará en Brasil. Las baries de açaí son ...

En esta tesis investigamos la clase de los qM3 retículos y la de los mM3−retículos o M3−retículos monádicos, que son M3−retículos dotados de un cuantificador existencial, en el primer caso, y en el segundo d...

We present ab initio quantum-mechanical molecular-dynamics simulations of the liquid-metal--amorphous-semiconductor transition in Ge. Our simulations are based on (a) finite-temperature density-functional theory of the o...

It has been recognized for some time that the spontaneous emission by atoms is not necessarily a fixed and immutable property of the coupling between matter and space, but that it can be controlled by modification of the...

Medical educators attempt to create reliable and valid tests and questionnaires in order to enhance the accuracy of their assessment and evaluations. Validity and reliability are two fundamental elements in the evaluatio...

All our former experience with application of quantum theory seems to say that what is predicted by quantum formalism must occur in the laboratory. But the essence of quantum formalism---entanglement, recognized by Einst...
