Sinopsis de las Thelypteridaceae de Brasil central y Paraguay [PDF]
Hoehnea, 2007 Aunque las Thelypteridaceae han sido tratadas en forma actualizada para Norteamérica, Mesoamérica, Guayanas, Ecuador, Perú, Argentina y sur y sudeste de Brasil, la región central de Sudamérica aún requería de una puesta al día. Con este motivo se estudiaron las especies de Thelypteridaceae de Paraguay y Brasil central, encontrándose 55 taxones, entre ...

Qualitative Inquiry in an Age of Educationalese [PDF]
, 2014 In this introduction we reflect on two key questions that initiated this special issue on qualitative inquiry: What can qualitative researchers do to regain their post-paradigm-wars cache? How do we avoid distracting “science wars” in the future?

Advanced Materials Technologies, EarlyView.This study formulated a 5Y‐PSZ zirconia paste for extrusion‐based additive manufacturing via direct ink writing, producing dense ceramic structures for dental applications. A colloidal approach with 47 vol% nanometric powder and tailored additives optimized rheology and printability.

The nature of the LINER in the galaxy NGC 404
, 2010 NGC 404, at a distance of 3.4 Mpc, is the nearest S0 galaxy. This galaxy harbors a LINER; however, since the spectrum does not show a broad H{\alpha} emission, it is not certain that this LINER is a low luminosity AGN and its nature is still an open ...

A simple model for inflation targeting in Brazil
Economia Aplicada, 2002 Based on a 6 equation model by Haldane and Battini (1999), we estimated a Phillips and an IS equations for Brazil after the Real Plan, in order to study the transmission mechanism of the monetary policy.

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems
Advanced Science, EarlyView.Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

On the Origins of Toughness in Corymbia calophylla (Marri Tree) Nuts
Advanced Science, EarlyView.We uncover the natural toughening mechanisms of the marri nut, including fiber pullout, crack deflection, and a viscoelastic matrix, which enable exceptional energy absorption and ductility comparable to Teflon, with an elastic modulus similar to acrylic.
