Variación en el color de la carne de terneros pasteros
3 páginas, 3 tablas.-- Ponencia presentada a las VIII Jornadas sobre Producción animal (AIDA) (Zaragoza 11 a 13 de mayo de 1999). Publicada en un número especial de la revista ITEA.De los múltiples parámetros que pueden ser evaluados para definir la calidad de la carne es de destacar el color, por su influencia en las preferencias de los consumidores por uno u otro tipo de carne, al ser apreciado de forma directa en los puntos de venta.
Ha sido puesto de manifiesto por distintos autores, (Renerre, 1990; Mandel et al, 1998, Albertí, Sañudo, 1998) la influencia que sobre la intensidad de color de la carne de vacuno puede tener el genotipo, el ejercicio físico, la alimentación, la edad de los animales, los tratamientos post-mortem de la carne etc. Cuando se pretende producir carne a partir de terneros pasteros, el color de ésta puede ser una característica importante por la influencia de la actividad física de los animales y la ingestión de forrajes verdes. Sin embargo, el periodo de acabado, previo al sacrificio podría determinar variaciones en la intensidad del color de la carne producida.
Por todo ello, el objetivo de este trabajo ha sido el estudio de los parámetros definitorios del color de la carne (L*, a* y b*) y la concentración de pigmentos hemínicos en músculo, de terneros pasteros sometidos a distintas estrategias de alimentación durante el periodo de acabado.Este trabajo ha sido realizado como parte del contrato de investigación entre la empresa ‘Núcleo de Explotaciones Agropecuarias de León, NEAL. SA.” y el CSIC y gracias a la colaboración prestada por la Estación Tecnológica de la Carne de la Junta de Castilla y León.Peer reviewe
Влияние крупности кварцевого сырья на кинетику процесса образования карбида кремния
AbstractThe joint European research project ELVA brings in line technology options and customer expectations for third generation electric vehicles. The objective is to develop innovative vehicle architectures fully exploiting freedoms in design that result from the electric drivetrain. This paper summarises the results of the first phase of the project which comprised deep technology and market forecasting as well as an open design contest for future electric vehicles. In the end, an outlook is given for the next phase in which three detailed vehicle concepts will be virtually developed and assessed with regard to several key requirements such as energy efficiency, material application and safety
Future research directions in injury biomechanics and passive safety research
There has been an increasing trend within the safety environment for funding to be directed towards applied
research or towards research developing commercially-exploitable systems. Funding mechanisms such
as the EU’s 6th Framework Programme and many national programmes focus on research of likely immediate
social benefit, reflecting the use of public finances. These programmes will continue to play an important
role in funding safety research, but they typically do not have guidelines specifically directed towards
fundamental research questions. Additionally, impartial advice is not always available to help programme
managers identify research priorities.
This review of biomechanics and passive safety research is intended for use by researchers who may be contemplating
research in certain areas and wish independent guidance on specific research questions. It is also intended for
use by research funding groups and programme managers who would like impartial guidance on basic research to
be supported. It covers engineering research directed at improving vehicles and safety systems for all types of road
user. It includes the main research and development tools such as dummy development and humanoid modelling
and the important area of crash injury data
Identification of road safety risk factors in Africa
The paper presents the results of the analysis of road safety data, collected within the research project "SaferAfrica
- Innovating dialogue and problems appraisal for a safer Africa", aiming to support policy makers and stakeholders
with evidence on critical risk factors, related actions and good practices drawn from high quality data and
knowledge. The project is funded by the European Union’s Horizon 2020 research and innovation programme.
The overall objective is to identify key risk factors affecting road safety in African countries. More specifically, a
data organisation and analysis system was developed for the data gathered in order to produce indicators and define
critical areas and challenges per topic and region of Africa. The analysis of the data for identifying key risk factors
was performed on 5 different topics and priority areas for road safety actions and interventions were highlighted
