Active monetary policy and instability in a phillips curve system
1998
The presence of nonlinearities in a Phillips curve system yields to complex dynamics, i.e., cyclical behavior that may (under some parametric set) become chaotic. This paper extends these conclusions by including an active monetary policy. We show how stabilization policy may lead to amplified instabilities and that agents' expectations tend to play a key role in the amount of these instabilities.
A Hooke's law-based approach to protein folding rate
2014
Kinetics is a key aspect of the renowned protein folding problem. Here, we propose a comprehensive approach to folding kinetics where a polypeptide chain is assumed to behave as an elastic material described by the Hooke[U+05F3]s law. A novel parameter called elastic-folding constant results from our model and is suggested to distinguish between protein with two-state and multi-state folding pathways. A contact-free descriptor, named folding degree, is introduced as a suitable structural feature to study protein-folding kinetics. This approach generalizes the observed correlations between varieties of structural descriptors with the folding rate constant. Additionally several comparisons am…

Contributions of statistical modelling for the understanding of the nivo-glaciological dynamics of a small arctic glacial basin (Austre Lovén glacier…
2021
Since the middle of the 19th century, the Earth has experienced a climate shift marked by a high rise in temperature (+ 0.85 °C over the period 1880-2012). The Arctic is the region of the world that is warming the most rapidly, at a rate of 2 to 3 times faster than the global average. In this context, all components of the Arctic cryosphere are experiencing a change in their dynamics. Because of their direct links with the atmosphere, glaciers are among the best indicators of these climate variations. Like other glaciers on the globe, the glaciers of Svalbard, which cover 60% of the archipelago’s surface, have been retreating since the end of the Little Ice Age. This retreat, which is refle…

Experimental and Numerical Simulations of Flow and Heat Transfer in Heat Exchanger Elements Using Liquid Crystal Thermography
2004
Experimental and numerical investigation of heat transfer and fluid flow were conducted for classic heat exchanger elements (flat plate with fin-tubes in-line, staggered and with vortex generators) and corrugated-undulated ducts under transitional and weakly turbulent conditions. The dependence of average heat transfer and pressure drop on Reynolds number and geometrical parameters was investigated. Distributions of local heat transfer coefficient were obtained by using liquid crystal thermography and surface-averaged values were computed. Three-dimensional numerical simulations were conducted by a finite-volume method using a low-Reynolds number k-e model under the assumption of fully deve…
Soil and organic carbon redistribution in a recently burned Mediterranean hillslope affected by water erosion processes
2022
Forest fires cause many changes in the physical, chemical and biological soil properties such as aggregation and soil organic carbon contents (SOC) as well as on soil hydrology and erosion processes. Most studies on post-fire soil erosion in Mediterranean environments have been plot-based and research at hillslope or broader scale is scarce. Understanding SOC nature, distribution and modifications, as produced by forest fires and erosion, has become crucial to model and define the role of soil erosion as source or sink of C, and to sustainably manage ecosystem services related to the soil resource. This research provides data about the loss and redistribution of soil and SOC in a Mediterran…
The influence of soil quality on life standard in Tutova Hills

Un Schiller para leer en voz alta [Ressenya]
2009
El profesor Martín Zubiría (Mendoza, Argentina, 1953), se propone en la edición que nos ocupa mantener viva la retórica enfática de Schiller ofreciendo al lector hispanohablante de los albores del siglo XXI una selección de versiones de su Gedankenlyrik en la que la fidelidad al sentido lo sea también a las palabras que lo expresan y a la estructura formal que lo sustenta.
Prefacio a la Enciclopedia filosófica para los últimos cursos de bachillerato de Hegel
2007
El presente volumen incluye el texto de Hegel Enciclopedia filosófica para los últimos cursos de bachillerato, seguido de un ensayo mío, «Sobre algunos conceptos básicos de la filosofía de Hegel». En 1840, Karl Rosenkranz, un discípulo de Hegel, autor de una Vida de Hegel, publicó bajo el título de Propedéutica filosófica un conjunto de textos destinados a la docencia que Hegel escribió entre 1808 y 1816, siendo director del Instituto de Enseñanza Media San Egidio de Nuremberg. La Philosophische Enziklopädie für die Oberklasse [Enciclopedia filosófica para los últimos cursos de bachillerato] (1808 ss.) es uno de los textos que Rosenkranz incluye en esa Propedéutica y que él destina a la ens…
