Total internal reflection microscopy (TIRM) measures the position of a Brownian particle above an interface by using its scattering of an evanescent wave. From the knowledge of the trajectory it is possible to reconstruct the interaction potential between the Brownian…

Concept maps are graphical representations of relationships among concepts that can be an effective tool for teaching, designing, and organizing information in a variety of library settings. Concept maps can be used wherever training or formal teaching occurs as a…

This essay illuminates the historical context of the contemporary language of globalization. It argues that the key concepts of the “global” began in ancient Greek thought about unseen space, before being reified through the Renaissance invention of the terrestrial globe.…

In June 2008, the Brazilian Interdisciplinary AIDS Association (ABIA) and the Indian NGO SAHARA submitted a joint pre-grant opposition to the patent application of Tenofovir Disoproxil Fumarate in India. This joint action provides a pertinent case model of the potential…

Interstellar dust was first identified through the extinction that it causes of optical starlight. Initially, observational and theoretical studies of extinction were made to identify simple ways of removing the effect of extinction. Over the last few decades it has…

In this study, we focus on the polarization angle of light scattered by terrestrial atmosphere-surface systems. The polarization angle describes the orientation of the plane in which the linearly polarized portion of light propagates. We show for skylight how this…

With the increasing demand for composite materials by the industry, the adhesive joints emer ge as an attractive alternative to traditional mechanical joints. The latter require as a preliminary step, the drilling of the laminates with consequent damage to the…

Potato is an important staple food and horticultural crop for Argentina and it is included in almost every meal prepared by households. The annual average per capita consumption of potatoes is 40 kg. Despite the rapid rise of supermarkets, small…

Torres-Saillant’s book contends, as its author explains, that as a region the Caribbean is a differentiated “civilizational” zone produced by the encounter of multiple cultures and by contending political and economic interests. This region, according to him, has produced an…
