El banco de semillas del suelo en Villarrobledo (Albacete) y su comarca

Se estudia por dos procedimientos distintos (extracción directa y siembra de tierra) el contenido de semillas del suelo de varias parcelas de la comarca de Villarrobledo (Albacete) pertenecientes a distintas etapas de sucesión y donde se habían realizado inventarios florísticos previos.

Análisis y distribución de la vegetacion macrófita en lagos de montaña de la provincia de León

Se ha realizado un estudio comparativo de la composición y zonación de la vegetación macrófita en tres lagos de montaña de la provincia de León: Truchillas, La Hafia e Isoba, basado en transectos y mapas de distribución. Se deduce que los factores primarios que controlan las diferencias esenciales entre los tres sistemas son la configuración de la orilla, ligada a las características fisiográficas de la zona de asentamiento, textura del sustrato, profundidad y composición química del agua. Se imponen cambios en la forma de crecimiento de las especies; y asi, mientras que los isoétidos dominan en Truchillas, en La Baña se desarrollan rizófitos de tallos largos y hojas flotantes, y en Isoba se introducen helófitos junto a una vegetación sumergida con y sin hojas flotantes.

Polycyclic aromatic hydrocarbons (PAHS) (I): Measures of prevention and control

Measures of prevention and control against polycyclic aromatic hydrocarbons (PAHs) focus on an official food control, a code of best practice to reduce PAHs levels by controlling industry and in the development of a chemopreventive strategy. Regulation (EU) 835/2011 establishes maximum levels of PAHs for each food group. In addition, Regulations (EU) 333/2007 and 836/2011 set up the methods of sampling and analysis for its official control. Scientific studies prove that the chemopreventive strategy is effective against these genotoxic compounds effects. Most chemopreventive compounds studied with proven protective effects against PAHs are found in fruit and vegetables.

La Inteligencia Competitiva en los procesos de internacionalización empresarial: Una guía de recursos de información para la empresa española y el periodismo económico

La información se ha convertido en un recurso imprescindible para el proceso de toma de decisiones en las empresas, y elemento fundamental en el proceso de Inteligencia Competitiva. La globalización económica y la libre circulación de mercancías, bien sea dentro de estructuras supranacionales o derivados de la firma de Tratados internacionales, han aumentado el número de competidores presentes en los mercados, pero también las oportunidades para acceder a otros mercados internacionales. Este trabajo describe los recursos de información más importantes que puede necesitar una empresa en su acceso a los mercados internacionales, y que proceden tanto de organismos públicos como privados.

La financiación por medio del crowdfunding del audiovisual: el caso del cortometraje "Juan y la nube"

En el artículo se analizan las posibilidades que tiene el crowfunding (CF) para financiar el audiovisual. Se explica el modelo de financiación del CF y se indican las distintas ventajas que reporta para el promotor este modelo de financiación alternativa. Además se exponen ampliamente las principales características del proceso de CF seguido para financiar el cortometraje Juan y la nube (que se alzó con el Goya al Mejor corto de animación en el año 2015). Se comentan también los principales motivos que llevan a los mecenas a financiar los proyectos

An Experimental Investigation into the Pressure Drop for Turbulent 90o Elbow Bends

The prediction of the pressure drop for turbulent single-phase fluid flow around sharp 90° bends is difficult owing to the complexity of the flow arising from frictional and separation effects. Several empirical equations exist, which accurately predict the pressure loss due to frictional effects. More recently, Crawford et al. [1] proposed an equation for the prediction of pressure loss due to separation of the flow. This work proposes a new composite equation for the prediction of pressure drop due to separation of the flow, which incorporates bends with ratio R/r <2. A new composite equation is proposed to predict pressure losses over the Reynolds number range 4 x 103-3 x 105. The predictions from the new equation are within a range of -4 to +6 per cent of existing experimental data.

Intercepting beats in predesignated target zones

Moving to a rhythm necessitates precise timing between the movement of the chosen limb and the timing imposed by the beats. However, the temporal information specifying the moment when a beat will sound (the moment onto which one must synchronise one's movement) is not continuously provided by the acoustic array. Because of this informational void, the actors need some form of prospective information that will allow them to act sufficiently ahead of time in order to get their hand in the right place at the right time. In this acoustic interception study, where participants were asked to move between two targets in such a way that they arrived and stopped in the target zone at the same time as a beat sounded, we tested a model derived from tau-coupling theory (Lee DN (1998) Ecol Psychol 10:221-250). This model attempts to explain the form of a potential timing guide that specifies the duration of the inter-beat intervals and also describes how this informational guide can be used in the timing and guidance of movements. The results of our first experiment show that, for inter-beat intervals of less than 3 s, a large proportion of the movement (over 70%) can be explained by the proposed model. However, a second experiment, which augments the time between beats so that it surpasses 3 s, shows a marked decline in the percentage of information/movement coupling. A close analysis of the movement kinematics indicates a lack of control and anticipation in the participants' movements. The implications of these findings, in light of other research studies, are discussed.

What Have We Learned in Five Decades of Neutralization Research?

Neutralization theory, though a popular framework for understanding deviant behavior, remains badly underdeveloped. Few attempts have been made to connect it to narrative and sociocognitive research in psychology and related fields. From this wider perspective, one reason neutralization theory has received only mixed empirical support is that it has been understood as a theory of criminal etiology. This makes little sense (how can one neutralize something before they have done it?) and makes the theory difficult to test. Neutralization should instead be seen as playing a role in persistence in or desistance from criminal behavior. The theory's central premises need to be substantially complicated. The notions that all excuses or justifications are "bad" and that reform involves "accepting complete responsibility" for one's actions are not tenable.
