Changing shapes: adiabatic dynamics of composite solitary waves

We discuss the solitary wave solutions of a particular two-component scalar field model in two-dimensional Minkowski space. These solitary waves involve one, two or four lumps of energy. The adiabatic motion of these composite non-linear non-dispersive waves points to variations in shape.Comment: 21 pages, 15 figures. To appear in Physica D: Nonlinear Phenomen

This is a second part of a fl oristic checklist of the calcareous Western Rif (N. Morocco), which comprises all vascular plants native or naturalized of the calcareous mountains between rivers Oued Laou and Oued Bouhya, which partly covers the Talassemtane National Park. This second part includes Dicotyledons from Caesalpiniaceae to Compositae, the rest of Dicotyledons, Monocotyledons still remaining for a third note that presumably will be published shortly. For each taxon the following items are included: accepted name, selected synonyms, localities where plants material has been collected, including previous records, general distribution, frequency and habitat. Some short comments are added to several taxa. A new combination is stablished: Digitalis obscura subsp. riphaea (Pau & Font Quer) Valdés & Mateos.Esta es la segunda parte de un catálogo florístico del Rif Occidental calizo (N de Marruecos), que incluye las plantas vasculares nativas o naturalizadas de los terrenos montañosos del Rif Occidental comprendidos entre los ríos Oued Laou y Oued Bouhya, que cubren en parte al Parque Nacional de Talassemtane.

Generalized Zeta Functions and One-loop Corrections to Quantum Kink Masses

A method for describing the quantum kink states in the semi-classical limit of several (1+1)-dimensional field theoretical models is developed. We use the generalized zeta function regularization method to compute the one-loop quantum correction to the masses of the kink in the sine-Gordon and cubic sinh-Gordon models and another two ${\rm P}(\phi)_2$ systems with polynomial self-interactions.Comment: 29 pages, 4 figures; version to appear in Nucl.

Orographic Effects on Berry Morphology and Chemical Composition of Carignan and Grenache Noir Grapes

A variation in the climatic parameters of an orographic vineyard influences the growth and developmentof vines and grapes. Understanding the effects of this is highly beneficial in determining how viticulturepractices can be modified to enhance grape quality. The aim of this study was to assess the effects of in-rowgrape position, altitude and vigour on berry morphology and grape maturity. The effects of vigour, altitudeand in-row grape position on berry weight and diameter, titratable acidity, pH and sugar concentrationof Carignan and Grenache noir grapes grown in a vineyard located in Priorat were investigated in the2021 vintage. The results show that Carignan grapes with a lower vigour demonstrated a higher sugarconcentration, berry weight and diameter, as well as lower titratable acidity, while the Grenache noirgrapes with a lower vigour achieved only a higher sugar concentration. The grapes at high altitude had ahigher sugar concentration in Carignan and higher titratable acidity in Grenache noir. Outer-row grapesof Carignan were characterised by lower titratable acidity and a higher sugar concentration, berry weightand diameter, while the outer-row grapes of Grenache noir displayed lower berry diameter, and a higherpH and sugar concentration. Vigour and in-row grape position have stronger effects on berry morphologyand chemical composition than altitude. Sugar concentration is more susceptible than other parameters tobe influenced by variability in the vineyard conditions

FAME. Aplicación web de apoyo al seguimiento, localización e integración de la información sobre flora amenazada y de interés generada en Andalucía

FAME es un sistema de información geográfica, integrado en la Red de Información Ambiental de Andalucía (REDIAM), de apoyo a la localización y seguimiento de la Flora Amenazada y de Interés de Andalucía, el cual centraliza la información que generan los distintos proyectos de la temática en el repositorio único de la Consejería de Medio Ambiente (CMA). Utilizando nuevas tecnologías se ha creado una herramienta Web que gestiona el recorrido completo de la información de Flora Amenazada, desde el levantamiento de la información, con el apoyo de una aplicación PDA, y la incorporación y edición de datos temáticos y gráficos, por medio de un visor cartográfico, hasta el proceso de validación temático para evitar errores en la incorporación de la información. En este proyecto se utiliza una arquitectura basada en la tecnología del software libre, destacando el visor geográfico desarrollado sobre OpenLayers, la aplicación para PDA desarrollada sobre el núcleo de Enebro y el uso de estándares OGC, tanto para la utilización de cartografía base mediante WMS, como para el acceso y la edición vía web a través de WFS-T. Este proyecto es una apuesta de la CMA por el uso del software libre como elemento principal en desarrollos complejosFAME is a geographic information system, integrated in the Andalusian Environmental Information Net (REDIAM), to support the location and tracking of Threatened and Interesting Flora of Andalusia, which centralizes the information generated in the different projects related with the thematic in the Unique Data Reservoir of Andalusian Environmental Council (CMA). A Web tool has been created using new technology which manages the complete Threatened Flora information layout, from the information gathering,, with the support of a PDA application, the incorporation and thematic data and graphic edition, using a cartographic viewer, to the thematic validation process to avoid mistakes in the information incorporation. This project uses an architecture based on free software technology, in Tecnologías de la Información Geográfica: la Información Geográfica al Servicio de los Ciudadanos.

Influence of soy oil source and supplementation of the diet with vitamin E and vi tamin C on performance and egg quality of Single Comb White Leghourn lyaing hens from forty four to fity six weeks of age

Two experiments (Exp.) were conducted to determine the AME content of refined soybean oil (SO), recycled soybean oil (RSO), and acidulated soybean oil soapstocks (ASO) and the effects of inclusion of vitamin E and vitamin C in diets containing 3.5% of these soy oils on performance and egg quality of Hy-line hens from 44 to 56 wks of age

Determinación del contenido en energía metabolizable de distintas fuentes de lípidos procedentes de la industria del aceite de soja

Los aceites vegetales se utilizan en la alimentación de gallinas ponedoras para aumentar la concentración energética de los piensos y como fuente de ácido linoleico. Además, Mateos y Sell (1981) han demostrado que la inclusión de grasas ralentiza la velocidad de tránsito de la digesta lo que favorece el contacto entre los nutrientes de la dieta y las enzimas digestivas, mejorando su utilización digestiva. Como consecuencia, la inclusión de grasas es una práctica común en la formulación de piensos comerciales para aves de puesta. El aceite de soja (AS) debido a su alto contenido energético y en ácido linoleico es el aceite de elección en piensos para avicultura pero su alto coste limita su utilización en piensos comerciales. Dos co-productos de la industria del aceite de soja, las oleínas (OAS) y el aceite de freiduría (ASR) podrían sustituir al AS en piensos para avicultura. El objetivo de este trabajo es determinar el contenido en energía metabolizable aparente (EMA) de estos aceites y comparar los resultados obtenidos utilizando dos metodologías de cálculo

Two-Dimensional Supersymmetric Quantum Mechanics: Two Fixed Centers of Force

The problem of building supersymmetry in the quantum mechanics of two Coulombian centers of force is analyzed. It is shown that there are essentially two ways of proceeding. The spectral problems of the SUSY (scalar) Hamiltonians are quite similar and become tantamount to solving entangled families of Razavy and Whittaker-Hill equations in the first approach. When the two centers have the same strength, the Whittaker-Hill equations reduce to Mathieu equations. In the second approach, the spectral problems are much more difficult to solve but one can still find the zero-energy ground states
