Nitrogen sources in the must are important for yeast metabolism, growth, and performance, and wine volatile compounds profile. Yeast assimilable nitrogen (YAN) deficiencies in grape must are one of the main causes of stuck and sluggish fermentation. The nitrogen requirement of Saccharomyces cerevisiae metabolism has been described in detail. However, the YAN preferences of non-Saccharomyces yeasts remain unknown despite their increasingly widespread use in winemaking. Furthermore, the impact of nitrogen consumption by non-Saccharomyces yeasts on YAN availability, alcoholic performance and volatile compounds production by S. cerevisiae in sequential fermentation has been little studied. With…
El 20-N o el azar en la Historia
2007
El azar, ese mismo vector que había hecho caer en la misma jornada a José Antonio Primo de Rivera y Durruti en nuestra guerra civil, tenía reservada una sarcástica mueca. Ocurrió el 20 de noviembre de 39 años más tarde, cuando aquéllos que tiraban los hilos de la escuálida vida de Francisco Franco decidieron (el los mismos sabrán, o quizá no, por qué) desconectar los débiles cables que lo ataban a la tierra . Barrieron así ritos y mitos. O tal vez no. Porque los mitos algo tienen de caprichoso: ora resisten las más briosas tempestades, ora se dejan llevar por suaves brisas. ¿Azar o necesidad? El texto compara los sepelios de los dos héroes de acuerdo con los códigos establecidos en el culto…
Horses Could Perceive Riding Differently Depending on the Way They Express Poor Welfare in the Stable
2020
International audience; This study investigated the relationships between four behavioral and postural indicators of a compromised welfare state in loose boxes (stereotypies, aggressive behaviors toward humans, withdrawn posture reflecting unresponsiveness to the environment, and alert posture indicating hypervigilance) and the way horses perceived riding. This perception was inferred using a survey completed by the usual riding instructor and during a standardized riding session (assessment of behaviors and postures, qualitative behavior assessment (QBA) and characterization of the horses' locomotion using an inertial measurement unit). In accordance with ear and tail positions and the QBA…
The Fight for the Self-Representation. Ainu Imaginary, Ethnicity and Assimilation
2017
Film representation of the Ainu people is as long as cinema but it has not remained stable over time. From the origins of cinema, Ainu people were an object of interest for Japanese and foreign explorers who portrayed them as an “other” savage and isolated from the modern world. The notion of “otherness” was slightly modified during wartime, as the Ainu were represented as other Japanese subjects within the “imperial family” and at the end of the fifties, during which entertainment cinema presented the Ainu according to the western Hollywood code on the one hand; and Mikio Naruse proposed a new portrayal Ainu focusing on the Ainu as a long discriminated social collective rather than as an e…
Analytical solution of kinematic wave time of concentration for overland flow under green-ampt infiltration
2015
In this paper the well-known kinematic wave equation for computing the time of concentration for impervious surfaces has been extended to the case of pervious hillslopes, accounting for infiltration. An analytical solution for the time of concentration for overland flow on a rectangular plane surface is derived using the kinematic wave equation under the Green-Ampt infiltration. The relative time of concentration is defined as the ratio between the time of concentration of an infiltrating plane and the soil sorptivity time scale, depending on the normalized rainfall intensity and a parameter synthesizing the soil and hillslope characteristics. It is shown that for a more complex case (corre…
Inverse Kinematics for a 7 DOF Robotic Arm Using the Redundancy Circle and ANFIS Models
2014
In this paper we have presented a method to solve the inverse kinematics problem of a redundant robotic arm with seven degrees of freedom and a human like workspace based on mathematical equations, ANFIS implementation and Simulink models. For better visualization of the kinematics simulation a CAD model that mimics the real robotic arm was created into SolidWorks® and then the CAD parts were converted into SimMechanics model.
Another Approach for Redundancy Resolution of a 7 DOF Robotic Arm
2015
In this paper we have presented a method to solve the inverse kinematics problem of a redundant robotic arm with seven degrees of freedom and a human like workspace based on mathematical equations, Fuzzy Logic implementation and Simulink models. For better visualization of the kinematics simulation a CAD model that mimics the real robotic arm was created into SolidWorks® and then the CAD parts were converted into SimMechanics model.
The inverse kinematics solutions of a 7 DOF robotic arm using Fuzzy Logic
2012
This paper focuses on modeling resolving and simulations of the inverse kinematics of an anthropomorphic redundant robotic structure with seven degrees of freedom and a workspace similar to human arm. Also the kinematical model and the kinematics equations of the robotic arm are presented. A method of resolving the redundancy of seven degrees of freedom robotic arm is presented using Fuzzy Logic toolbox from MATLAB®.

La resolución de casos prácticos de Derecho del Trabajo a través del cine
2016
La explicación, análisis y posterior resolución de supuestos prácticos constituye una de las formas más eficaces y óptimas para lograr que los estudiantes profundicen en la materia que se les explica, consoliden conocimientos teóricos y desarrollen su capacidad de argumentación jurídica y de espíritu crítico. Todos estos objetivos se potencian cuando la llamada “técnica del caso” va acompañada de la visualización de obras cinematográficas que logran reflejar la realidad del tiempo en que se vive. Pues bien, aprovechando la ventaja que supone que el Derecho del Trabajo sea una disciplina jurídica próxima y cercana a la sociedad, se aborda la posibilidad en este trabajo de complementar el apr…
