Path integral solution for non-linear system enforced by Poisson White Noise

2008

Abstract In this paper the response in terms of probability density function of non-linear systems under Poisson White Noise is considered. The problem is handled via path integral (PI) solution that may be considered as a step-by-step solution technique in terms of probability density function. First the extension of the PI to the case of Poisson White Noise is derived, then it is shown that at the limit when the time step becomes an infinitesimal quantity the Kolmogorov–Feller (K–F) equation is fully restored enforcing the validity of the approximations made in obtaining the conditional probability appearing in the Chapman Kolmogorov equation (starting point of the PI). Spectral counterpa…

Primary- and secondary-octahedral distortion factors in bis(1,4-H2-1,2,4-triazolium) pentabromidoantimonate(III) –1,4-H2-1,2,4-triazolium bromide

2015

Abstract The analysis of octahedral distortion in the structure of inorganic–organic (C2H4N3)2[SbBr5]·(C2H4N3)Br (BTPTB) bromidoantimonate(III) determined at 295 and 85 K, supported by the Hirshfeld surface analysis and the data retrieved from the Cambridge Structural Database, is presented. The anionic substructure of BTPTB is built from distorted [SbBr6]3− octahedra that are connected by the cis corners forming polymeric one-dimensional [{SbBr5}n]2n− zig-zag chains running parallel to the a axis and isolated Br− ions. The organic substructure consists of the fully ordered 1,4-H2-1,2,4-triazolium cations. The oppositely charged substructures are linked by the system of N(C)–H⋯Br hydrogen b…

Salbutamol Transport and Deposition in the Upper and Lower Airway with Different Devices in Cats: A Computational Fluid Dynamics Approach

2021

Simple Summary Administration of inhaled salbutamol via metered-dose inhalers can effectively treat bronchoconstriction. Different devices are used for the delivery of this drug in cats, either in the hospital or at home, for long-term treatment. Effective drug administration may depend on the drug delivery device as well as patient cooperation. By using non-invasive computational fluid dynamics techniques, the impact of these devices on the deposition and transport of salbutamol particles in the cat airways was simulated and assessed. The results confirm a variable drug distribution depending on the device used. The percentage of particles reaching the lung was reduced when using spacers a…

Changes in soil fauna 10 years after forest harvestings: Comparison between clear felling and green-tree retention methods

2009

Abstract We studied the responses of soil decomposer animals to clear felling and alternative, green-tree retention harvesting methods (GRT) in Norway spruce forests in Finland. The study plots which were sampled for immediate treatment effects (up to three years) were resampled after 10 years. We hypothesized that responses of decomposers still depends on the level of GTR. The treatments, in addition to untreated controls (100% retained), were: (1) selection felling (70% dispersed tree retention), (2) and (3) gap felling with and without site preparation, respectively (three small gaps were felled in a 1-ha area and 50% of the stand volume was retained), (4) retention felling (10% of the s…

Short-term responses of soil macroarthropod community to clear felling and alternative forest regeneration methods

2003

Abstract We studied the influence of clear felling and new alternative forest regeneration methods on soil macroarthropods during the first 3 years after the harvesting. We focused on changes in the abundances of functional groups, and community structure at the levels of species (Coleoptera) or higher taxa. The experiment was carried out in central Finland in spruce (Picea abies (L.) Karst.) stands on 1 ha study plots. The following five treatments were used in addition to the untreated controls: (1) selection felling (70% of the stand volume retained), (2) gap felling (0.1–0.2 ha gaps felled), (3) gap felling with site preparation, (4) retention felling (small groups of trees retained on …

Moriscos y curas: la denuncia profética del Dr. Frago (1560)

1992

La evangelización de los moriscos valencianos resultó prácticamente imposible por su propia resistencia cultural y por la falta de dedicación de los curas encargados de ella. Sin embargo, a principios del reinado de Felipe II se pensó que la empresa era viable. El Dr. Frago, responsable de una parroquia de moriscos, fue -a principio de los años 60- un importante activista en favor del esfuerzo evangelizador. Amenazo con graves males a Felipe II si no tomaba medidas contra los señores que explotaban a los moriscos y que encubrían su islamismo, creyendo que, eliminado este obstáculo, la evangelización progresaría.

Uniformidad y diversidad en la codificación civil

2009

En un coloquio sobre exclusión de minorías, me pareció de interés abordar problemas de la codificación del siglo XIX. Desde la Conquista se había extendido el derecho castellano de Partidas y Recopilaciones a las Indias, frente a los derechos propios y costumbres indígenas. En los dos últimos siglos un proceso de uniformidad profundo se extendió por Europa y América con las revoluciones y la aplicación del Code des français de 1804, más o menos retocado. El antiguo derecho admitía las costumbres o usos inveterados por más de diez o veinte años, demostradas en dos juicios, incluso contra leyes, pero ahora se impone el imperio de la ley. Además unifica unas leyes únicas aplicables a todos los…
