El dinosaurio de Alba.

Se expone una experiencia de investigación escolar en la Escuela Infantil Aire Libre, de Alicante. Se resalta la importancia del aprendizaje activo y en grupo y por ello se destaca la necesidad de crear un contexto afectivo, material y colaborativo en una primera fase. Los niños son los que eligen el tema que se va a trabajar: los dinosaurios. Se relatan las actividades que se llevan a cabo durante cuatro semanas en las que también se implica a las familias. Los niños aportan sus propios materiales y se realizan talleres, actividades teatrales y de dibujo, excursiones y debates, entre otros.

Resumen basado en el de la publicación

La niña en el cine Ecuador 2008 a 2015. En el nombre de la hija de Tania Hermida; En espera de Gabriela Calvache; Domingo Violeta, Ánima, Nuca y Alba de Ana Cristina Barragán

La niña ha sido representada en el cine ecuatoriano de 2008 a 2015, con carácter protagónico, en seis películas -dos largometrajes y cuatro cortometrajes-, todas en el género de la ficción cinematográfica y en todos los casos escritas y dirigidas por mujeres. Descubrir las huellas dejadas por estas obras en sus representaciones es el objetivo central de esta investigación que se limita a seis películas cuya protagonista es una niña. Huellas de la expresión artística contra-hegemónica y liberadora de la persona, sujeto de derechos y agente social que son las niñas, en relación a los imaginarios y construcciones sociales que los medios de comunicación así como el arte permiten reforzar o replantear. La investigación teórica, entrevistas a profundidad y el análisis de la imagen han sido los métodos, técnicas e instrumentos utilizados a fin de lograr los necesarios referentes, insumos y criterios para lograr una mirada integral a partir de las evidencias particulares que las autoras y sus obras nos dejan. Así se ha logrado una aproximación a la representación de la niña que las autoras han hecho en sus películas, respondiendo a sus propias experiencias de vida y a la necesidad de expresar libremente sus emociones y sentimientos.

A novel component of cannabis extract potentiates excitatory synaptic transmission in rat olfactory cortex in vitro

Cannabis is a potential treatment for epilepsy, although the few human studies supporting this use have proved inconclusive. Previously, we showed that a standardized cannabis extract (SCE), isolated Delta(9)-tetrahydrocannabinol (Delta(9)-THC), and even Delta(9)-THC-free SCE inhibited muscarinic agonist-induced epileptiform bursting in rat olfactory cortical brain slices, acting via CB1 receptors. The present work demonstrates that although Delta(9)-THC (1microM) significantly depressed evoked depolarizing postsynaptic potentials (PSPs) in rat olfactory cortex neurones, both SCE and Delta(9)-THC-free SCE significantly potentiated evoked PSPs (all results were fully reversed by the CB1 receptor antagonist SR141716A, 1microM); interestingly, the potentiation by Delta(9)-THC-free SCE was greater than that produced by SCE. On comparing the effects of Delta(9)-THC-free SCE upon evoked PSPs and artificial PSPs (aPSPs; evoked electrotonically following brief intracellular current injection), PSPs were enhanced, whereas aPSPs were unaffected, suggesting that the effect was not due to changes in background input resistance. Similar recordings made using CB1 receptor-deficient knockout mice (CB1(-/-)) and wild-type littermate controls revealed cannabinoid or extract-induced changes in membrane resistance, cell excitability and synaptic transmission in wild-type mice that were similar to those seen in rat neurones, but no effect on these properties were seen in CB1(-/-) cells. It appears that the unknown extract constituent(s) effects over-rode the suppressive effects of Delta(9)-THC on excitatory neurotransmitter release, which may explain some patients' preference for herbal cannabis rather than isolated Delta(9)-THC (due to attenuation of some of the central Delta(9)-THC side effects) and possibly account for the rare incidence of seizures in some individuals taking cannabis recreationally

Characterising errors in airborne laser altimetry data to extract soil roughness

Airborne laser altimetry has the potential to make frequent detailed observations that are important for many aspects of studying land surface processes. However, the uncertainties inherent in airborne laser altimetry data have rarely been well measured. Uncertainty is often specified as generally as 20cm in elevation, and 40cm planimetric. To better constrain these uncertainties, we present an analysis of several datasets acquired specifically to study the temporal consistency of laser altimetry data, and thus assess its operational value. The error budget has three main components, each with a time regime. For measurements acquired less than 50ms apart, elevations have a local standard deviation in height of 3.5cm, enabling the local measurement of surface roughness of the order of 5cm. Points acquired seconds apart acquire an additional random error due to Differential Geographic Positioning System (DGPS) fluctuation. Measurements made up to an hour apart show an elevation drift of 7cm over a half hour. Over months, this drift gives rise to a random elevation offset between swathes, with an average of 6.4cm. The RMS planimetric error in point location was derived as 37.4cm. We conclude by considering the consequences of these uncertainties on the principle application of laser altimetry in the UK, intertidal zone monitoring.

Seed storage of Avicennia alba B1

Seeds of Avicennia alba BI. matured at high moisture content and were sensitive to desiccation: no seeds survived desiccation below 35% moisture content. The effect on survival of a factorial combination of five moist storage treatments (fresh seeds in a polyethylene bag, open with water sprayed over regularly, mixed with sand at 10% moisture content, mixed with moist paddy hulls, or naked seeds mixed with sand at 10% moisture content) and three temperatures (28-30degreesC, 17degreesC and 8-10degreesC) was investigated. In addition, seeds were mixed with sand at 5% moisture content and stored at 17degreesC in order to determine the effect of sand moisture content on seed moisture content and viability during storage. Avicennia alba showed recalcitrant seed storage behaviour, but 75% of the seeds remained viable after four months' moist (45-47% moisture content) storage in 10% moisture content sand at 17degreesC.
