[en] Public administrations have in recent years developed programs of public funding for innovation to boost the competitiveness of business. The study of how companies have used these funding sources generates knowledge to improve the design of support for private innovation and to provide advice for innovative companies. This paper investigates these issues in the agri-food sector which is of particular interest as it is comprised mainly of small and medium enterprises with a wide regional presence and interaction with their local environment. A survey on technological innovation was used to estimate panel logit models with random effects, taking as dependent variables three types of funding: regional, state and European Union. The results generally show a positive relationship between innovation efforts and access to public funding, but also significant differences between types of funding and between sectors. Food companies that obtain public funding tend to have a more innovative profile than Agriculture ones. Both types of firm present higher probabilities than others companies when it comes to gaining access to regional funding, though the opposite often occurs in the case of state funding. Firm size is not significant for regional funding and no overlap was detected between regional and state funding. The financial crisis has adversely affected regional and national aid, which experienced a significant decrease in the period from 2008 to 2013.
[en] There are currently some projects ongoing aimed at the construction of a commercial fusion reactor capable of operating in a controlled manner and generating clean energy, and one of the most important initiatives is the ITER Project in Cadarache (France). This reactor is based on the confinement of plasma through magnetic fields, being one of the most important technological challenges the cooling of complex components under extreme conditions of temperature and radiation. This article aims to briefly show some aspects related to the calculation of such components using computational fluid dynamics tools (CFD) noting that these studies have been focused on the vacuum vessel that contains the radiation emitted by the plasma and the evacuation of the generated heat
[es]A lo largo de los últimos años, la fusión nuclear ha cobrado cada vez más importancia dentro del panorama de la investigación de nuevas fuentes de energía. Actualmente existen varios conceptos mediante los que se pretende alcanzar la fusión nuclear con vistas a construir un reactor comercial capaz de generar energía limpia. Una de las iniciativas más importantes en el desarrollo de la fusión nuclear es el reactor experimental ITER en construcción en Cadarache, Francia. Este reactor, basado en el confinamiento por campos magnéticos del plasma que genera la reacción de fusión presenta un reto tecnológico en un amplio abanico de disciplinas, entre ellas la refrigeración de complejos componentes bajo condiciones extremas tanto térmicas como de radiación. IDOM ha participado desde hace años en el cálculo de dichos componentes mediante herramientas de dinámica de fluidos computacional (CFD) y ha desarrollado una metodología propia que permite la simulación de grandes estructuras y su análisis detallado desde el punto de vista de diseño, operativo y de seguridad. Estos estudios se han centrado en la refrigeración de la vasija de vacío que contiene la radiación emitida por el plasma y evacúa el calor que éste genera para la posterior generación de electricidad. La tecnología desarrollada por IDOM para la tecnología de fusión también se ha aplicado con éxito a otras disciplinas dentro de la industria nuclear. La propuesta es explicar, como introducción, ITER en el marco de los trabajos que se están realizando con CFD. Después una primera parte en la que se explicará en qué consisten los cálculos y para qué se aplican, y una segunda parte en la que extendemos esta tecnología a otros campos relacionados con la tecnología nuclear.
[en] Full text: Collecting scientific evidence on the human, social and ethical dimensions in energy systems is a fundamental tool for understanding (and intervening in) the acceptance of energy technologies, the siting of energy generation facilities, and the promotion of measures for risk mitigation and safety. Furthermore, this key role of social research in energy fully aligns with proposals for more open and responsive modes of research and science policy-making, as illustrated by contemporary EU-wide policy discourses on “Science with and for society” and “responsible research and innovation”. In the fusion domain, and since 1996, a specific research programme — currently known as Socio-economic Studies, or SES — has been dealing with the social and the socio-economic dimension of fusion. The SES social research has so far focussed on generating evidence regarding the conditions for social acceptance of fusion — currently as a research endeavour and in the future as an energy source — as well as the barriers and constraints for acceptance and suitable energy governance. Stakeholder engagement, lay attitudes and media analysis and media framing are our three main fields of research. This paper presents the key challenges and findings from social research on fusion together with its very practical implications for the fusion community, such as promoting the engagement of the fusion community with stakeholders and the public, enhancing the communication strategies of fusion research, including additional variables in the economic model of the global energy system or making fusion research more responsive to societal concerns.

[en] The European Space Agency (ESA) has a very active Science Programme, with many missions in operation in space, and others being studied, developed or being prepared for launch. The ESA Science missions are very diverse, ranging from astrophysics observatories to probes visiting other parts of our planetary system, studying other planets, comets and our sun. Their success would not be possible without the development and use of novel technologies. Future ESA Science missions are extensively studied before their adoption for flight, and associated technologies are developed in industrial activities funded by ESA. An elaborated technology development plan is being regularly updated, and offers opportunities for innovative companies and research institutions to contribute to the ESA Science Programme. (author)
[en] This book is a tribute to all with inquisitive minds, including fellow scientists, and those interested in the agarwood or karas trees (Aquilaria spp.), especially in relation to the highly prized gaharu oleoresin. When Malaysian Nuclear Agency (Nuclear Malaysia) was approached on the possibility of nuclear technology applications in providing scientific information on some issues, viz. detection and estimation of gaharu resin in Aquilaria stands, quality and grading of gaharu wood chip and gaharu oil, and possibility of generating new variants through radiation mutagenesis, this led to the involvement of our scientist from different disciplines, embarking on fusion of technologies - nuclear technology, agrotechnology, biotechnology, and IT, among others, on a new subject - the enigmatic tree with aromatic oleoresin. These became a challenge to all of us, being novices to Aquilaria and its related activities. While we treasure traditional knowledge passed from generation to generation, it is inherent upon scientists and knowledge workers to infusenew knowledge via science, technology and innovation, to invigorate and transform the indigenous, traditional technology-based industry into a modern and vibrant bioeconomy. We hope that our short treatise on Research and Development of agarwood and the outputs, featuring nuclear technology, will provide a glimpse to unraveiling, albeit a little, the mystery enshrouding the gaharu industry.

[en] Gaharu is a rare oleoresin-impregnated wood extracted from the karas or tengkeras trees known as Aquilaria spp., which are widely distributed in Malaysia. When burnt, gaharu produces a fragrance that is believed to have therapeutic properties and is often used to produce perfume and incense that fetches exceptionally high prices, particularly in the Middle Eas. Oil extracted from gaharu is also highly prized by European perfumery because of its ability to retain scent. The timber is used for making high quality furniture. The best gaharu yields are from trees of 20-30 years of age or more but the essential oil or oleoresin is produced by trees as young as 10-15 years. (author)
[en] Agarwood is a resin-impreganted wood produced from trees of the Aquilaria spp. Under natural conditions, gaharu resin can only be produced by natural wounding caused., for example, by lightning or by animals. However, the gaharu resin produced was very low in yield and only accumulated at certain spots where the injuries were located. Moreover, the natural process of gaharu resin accumulation is a time consuming process, usually taking 10 to 20 years before a good harvest possible. To overcome this problem, a gaharu resin inducement technology has been developed to enhance resin production, thus maximising gaharu resin accumulation throughout the stem abd shortening resin production time to only 1 to 2 years.
