Do Carbonate Precipitates Affect Dissolution Kinetics?

G.J. Stockmann
Experiments were performed in aqueous solutions 1) supersaturated with respect to calcite for up to 63 days, and 2) strongly undersaturated with respect to calcite and other secondary phases for up to 164 days. Inlet solutions were comprised of NaHCO3, CaCl2, NH4Cl, NaOH, and/or HCl with ionic strengths ranging from 0.01 to 0.09 mol/kg. In the experiments performed at 25 °C, calcite nucleated and grew extensively on both the diopside surfaces, and as b1000 μm...

Heat As A Proxy Tracer For Gas Exchange Measurements In The Field: Principles And Technical Realization

Horst Haußecker, Sebastian Reinelt & Bernd Jähne
An infrared technique to investigate the transfer processes across the aqueous
mass boundary layer is presented. This controlled flux technique (CFT)
uses heat as a proxy tracer for gases to allow for fast and local measurements
of the gas transfer rate. Three different ways of gas transfer velocity
measurements are investigated. The first one, the steady state method is a
straightforward way to probe the basic unknowns needed to directly compute
the gas transfer velocity...

Co2 Storage Potential Of Basaltic Rocks In Iceland And The Oceanic Ridges.

Wiese F Snæbjörnsdóttir SÓ
Iceland is the largest landmass found above sea level at the mid-ocean ridges, about 103,000 km2 mostly made of basaltic rocks (~90%). Theoretically much of Iceland could be used for injection of CO2, fully dissolved in water. Most of the pore space in the older rocks is filled with secondary minerals, thus the young and porous basaltic formations, found within the active rift zone and covering about one third of Iceland, are the most feasible...

¿Qué Hay Más Allá De La Conciencia? La Reelaboración Nietzscheana De Las Relaciones Cuerpo-Mente En Términos De Poder

Óscar Quejido Alonso
La crítica nietzscheana a la noción de alma se revelará inevitablemente asociada a su reivindicación más general del papel desempeñado por el cuerpo, en su relación con el pensamiento consciente. Esta alternativa puede ser considerada un nuevo marco interpretativo y conceptual, desde el que abordar el tema de las relaciones entre cuerpo y mente, a partir de la redefinición de la psicología en términos de relaciones de poder

Hacía Una Hermenéutica De Herencia Aristotélica

Héctor Sevilla Godínez
En el presente artículo se profundiza en la ineludible función de la conciencia como precursora de la noción primigenia que faculta el conocimiento a través del lenguaje. Del mismo modo, se aborda la posibilidad de la implicación del concepto de la Nada en la hermenéutica aristotélica, haciendo énfasis en su relación con las representaciones ante el mundo de lo cognoscible. Todo ello apunta al vislumbre de una filosofía de las interpretaciones o una hermenéutica de...

Implicancias Del Cruce Entre Conocimiento, Ideología Y Subjetividad En Althusser

Gabriel Martín Torres
El objetivo del presente trabajo consiste en reconstruir el concepto de autonomía política contemplada por Louis Althusser, a partir de la exploración de dos dominios básicos de su teoría: la gnoseología que él advierte en el materialismo dialéctico, y las implicancias que la imbricación de las nociones “ideología” y “subjetividad” guarda para el pensamiento de una práctica política materialista. En su lectura del materialismo dialéctico Althusser había enfatizado la exigencia de considerar a la ideología...

Realismo De Los Supuestos En Economía: Un Análisis Bajo La Lógica De Los Procesos Socioeconómicos

Leonardo Ivarola
El realismo de supuestos es una discusión permanente dentro de la filosofía de la economía. Uno de los trabajos más referidos en este marco es el de Milton Friedman. Este trabajo defiende el uso de supuestos irrealistas, no sólo por una cuestión pragmática, sino también por las dificultades intrínsecas de determinar el grado de realismo de los supuestos. Los realistas, por su parte, han criticado el uso de supuestos irrealistas – como el supuesto de...
