From Las Casas to Che : An Introduction to Contemporary Latin America

Spanish America is a geographical area within which the power struggle between archaic and modern traits stands out very clearly. The reason for this might be found in the significant initial historical distance between the society of the Europeans and the society of the Indians. For this reason, it is very difficult to comprehend the history of ideas of this area, if one disregards the dialectics

Process Analytical Tools for the Monitoring and Characterization of Bacterial Toxins

In the era of proteomics, glycomics and ultimately metabolomics, with constantly increasing knowledge regarding the human biosystem, the number of specialized therapeutic agents which will be developed against different diseases is predicted to be on the upswing. An increasing portion of these new drugs will, according to recent predictions (Labrou, 2003), be of proteinaceous origin produced accor

Revisiting the PnP Problem: A Fast, General and Optimal Solution

In this paper, we revisit the classical perspective-n-point (PnP) problem, and propose the first non-iterative O(n) solution that is fast, generally applicable and globally optimal. Our basic idea is to formulate the PnP problem into a functional minimization problem and retrieve all its stationary points by using the Gr¨obner basis technique. The novelty lies in a non-unit quaternion representati

Modeling of two-phase flow in a cathode duct of PEM fuel cells

In this study, a fully three-dimensional model has been developed to simulate two-phase, multi-component gas and heat transport processes in a PEMFC cathode duct. The effects of the electrochemical reactions on the heat generation and mass transfer have been taken into account. Based on the calculated values of water vapor partial pressure and temperature, occurrence of liquid water has been predi
